                         POOLING AND SERVICING AGREEMENT

     This Pooling and Servicing Agreement (this "Agreement") is dated and
effective as of November 1, 2003, among MERRILL LYNCH MORTGAGE INVESTORS, INC.,
as Depositor, KEYCORP REAL ESTATE CAPITAL MARKETS, INC., as Master Servicer,
ARCAP SERVICING, INC., as Special Servicer, LASALLE BANK NATIONAL ASSOCIATION,
as Trustee, and ABN AMRO BANK N.V., as Fiscal Agent.

                             PRELIMINARY STATEMENT:

     The Depositor intends to sell mortgage pass-through certificates
(collectively, the "Certificates"), to be issued hereunder in multiple classes
(each, a "Class"), which in the aggregate will evidence the entire beneficial
ownership interest in a trust fund (the "Trust Fund") to be created hereunder,
the primary assets of which will be the Mortgage Loans.

     As provided herein, the Trustee will elect to treat the segregated pool of
assets consisting of all of the Mortgage Loans (exclusive of that portion of the
interest payments thereon that constitute Additional Interest) and certain other
related assets subject to this Agreement as three separate REMICs ("77 West
Wacker Drive Loan REMIC," "REMIC I" and "REMIC II") for federal income tax
purposes.

     As provided herein, the Trustee will elect to treat the segregated pool of
assets consisting of the 77 West Wacker Drive Mortgage Loan as a REMIC for
federal income tax purposes, and such segregated pool of assets will be
designated as "77 West Wacker Drive Loan REMIC." The Class R-LR Residual
Interest will represent the sole class of "residual interests" in the 77 West
Wacker Drive Loan REMIC for purposes of the REMIC Provisions under federal
income tax law, and will be represented by the Class R-LR Certificates. For
federal income tax purposes, the 77 West Wacker Drive Loan REMIC Regular
Interests will be uncertificated and will be held by REMIC I.

     As provided herein, the Trustee will elect to treat the segregated pool of
assets consisting of all the Mortgage Loans (exclusive of the 77 West Wacker
Drive Mortgage Loan) and all the 77 West Wacker Drive Loan REMIC Regular
Interests as a REMIC for federal income tax purposes, and such segregated pool
of assets will be designated as "REMIC I." The Class R-I Residual Interest will
represent the sole class of "residual interests" in REMIC I for purposes of the
REMIC Provisions under federal income tax law, and will be represented by the
Class R-I Certificates.

     As provided herein, the Trustee will elect to treat the segregated pool of
assets consisting of all of the REMIC I Regular Interests as a REMIC for federal
income tax purposes, and such segregated pool of assets will be designated as
"REMIC II". The Class R-II Certificates will evidence the sole class of
"residual interests" in REMIC II for purposes of the REMIC Provisions under
federal income tax law. For federal income tax purposes, each Class of the
Regular Certificates will be designated as a separate "regular interest" in
REMIC II for purposes of the REMIC Provisions under federal income tax law.

     The following table sets forth the Class or Component designation, the
corresponding REMIC I Regular Interest (the "Corresponding REMIC I Regular
Interest"), the

REMIC I Principal Balance, the Corresponding Components of the Class X
Certificates (or, where applicable, the Class WW-X Certificates) and the
Original Class Principal Balance for each Class of Sequential Pay Certificates
and Class WW Principal Balance Certificates (the "Corresponding Certificates").

     (1) The REMIC I Regular Interest and the Component of the Class X
Certificates that corresponds to any particular Class of Sequential Pay
Certificates also correspond to each other and, accordingly, constitute the
"Corresponding REMIC I Regular Interest" and the "Corresponding Component",
respectively, with respect to each other and such particular Class of Sequential
Pay Certificates; provided that, if the table above reflects that multiple REMIC
I Regular Interests and multiple Components of the Class X Certificates
correspond to any particular Class of Sequential Pay Certificates, then each of
them shall constitute a "Corresponding REMIC I Regular Interest" or a
"Corresponding Component", as applicable, with respect to such Class of
Sequential Pay Certificates, but shall constitute the "Corresponding REMIC I
Regular Interest" or the "Corresponding Component" with respect to each other
only if the designation for such REMIC I Regular Interest ends in the same
number as the designation for such Component. The REMIC I Regular Interest and
the 77 West Wacker Drive Non-Pooled Component that correspond to any particular
Class of Class WW Principal Balance Certificates also correspond to each other
and, accordingly, constitute the "Corresponding REMIC I Regular Interest" and

     (2) For purposes of making distributions to the Class A-1, Class A-2, Class
A-3, Class A-4 and Class A-1A Certificates, the pool of Mortgage Loans will be
deemed to consist of two distinct Loan Groups, Loan Group 1 and Loan Group 2.

     Three mortgage loans in the aggregate original principal amount of $950,000
(the "Subordinate Companion Loans", as defined below) are not part of the Trust
Fund but are each secured by a Mortgage that is the same as the Mortgage that
secures a Mortgage Loan that is part of the Trust Fund. As and to the extent
provided herein, the Subordinate Companion Loans will be serviced and
administered in accordance with this Agreement. Amounts attributable to the
related Subordinate Companion Loans will not be assets of the Trust Fund, and
will be beneficially owned by the Companion Holders.

     The Fairfield Commons Total Loan is a pari passu split loan structure
comprised of the Fairfield Commons Pooled Mortgage Loan and the Fairfield
Commons Pari Passu Companion Loan. The Fairfield Commons Pari Passu Companion
Loan is intended to be, but is not yet, included in another securitization, the
Credit Suisse First Boston Mortgage Securities Corp., Commercial Mortgage
Pass-Through Certificates, Series 2003-C5 securitization (the "Series 2003-C5
Securitization"). The Fairfield Commons Intercreditor Agreement provides that

                                       4
<PAGE>

the Fairfield Commons Total Loan will be initially serviced and administered
under this Agreement by the Master Servicer, the Special Servicer, the Trustee
and the Fiscal Agent, and that, for so long as the Fairfield Commons Pari Passu
Companion Loan is included in the Series 2003-C5 Securitization, the Fairfield
Commons Total Loan will be serviced under the pooling and servicing agreement
relating to the Series 2003-C5 Securitization (the "Series 2003-C5 Pooling and
Servicing Agreement"), during which time the Special Servicer will have no
servicing responsibilities with respect to the Fairfield Commons Pooled Mortgage
Loan or the Fairfield Commons Pari Passu Companion Loan or the related Mortgaged
Property. For so long as the Fairfield Commons Pari Passu Companion Loan is
included in the Series 2003-C5 Securitization, the Master Servicer, the Trustee
and the Fiscal Agent will have limited servicing and administration
responsibilities under this Agreement (such as preparing CMSA servicing reports,
remitting collections, and making P&I Advances) with respect to the Fairfield
Commons Pooled Mortgage Loan, but will have no servicing and administration
responsibilities whatsoever with respect to the Fairfield Commons Pari Passu
Companion Loan. In that regard, when this Agreement references or provides for
amounts collected or received by or on behalf of the Master Servicer or the
Special Servicer with respect to the Fairfield Commons Pooled Mortgage Loan
these references or provisions are deemed to include all amounts collected or
received by the servicers or the trustee under the Series 2003-C5 Pooling and
Servicing Agreement on behalf of the Trust Fund as the holder of the Fairfield
Commons Pooled Mortgage Loan and, if applicable, remitted to the Master
Servicer, the Special Servicer, the Trustee, or the Fiscal Agent.

     The portion of the Trust Fund consisting of: (i) the Additional Interest
and the Additional Interest Account and (ii) amounts held from time to time in
the Additional Interest Account that represent Additional Interest shall be
treated as a grantor trust (the "Grantor Trust") for federal income tax
purposes. As provided herein, the Trustee shall take all actions necessary to
ensure that the portion of the Trust Fund consisting of the Grantor Trust Assets
maintains its status as a "grantor trust" under federal income tax law and not
be treated as part of 77 West Wacker Drive Loan REMIC, REMIC I or REMIC II.

     In consideration of the mutual agreements herein contained, the Depositor,
the Master Servicer, the Special Servicer, the Trustee and the Fiscal Agent
agree as follows:

the case may be, that, as determined by the Master Servicer, the Special
Servicer, the Trustee or the Fiscal Agent in accordance with the Servicing

determinations at any time and, consistent with the Servicing Standards, may
obtain from the Special Servicer any reasonably required analysis, Appraisals or
market value estimates or other information in the Special Servicer's possession

Servicer's, the Trustee's or the Fiscal Agent's determination (or that of the
applicable Person under the Series 2003-C5 Pooling and Servicing Agreement) as

     proceeding involving the related Mortgagor or by reason of a modification,
     waiver or amendment granted or agreed to by the Special Servicer pursuant
     to Section 3.20);

          (ii) with respect to the circumstances described in clauses (b), (d),
     (e) and (f) above, when such circumstances cease to exist in the good faith

above exists that would cause such Mortgage Loan (or, with respect to such
Companion Loan, the related AB Mortgage Loan, or, as the case may be, with

     "Workout Fee": With respect to each Corrected Mortgage Loan, the fee
designated as such and payable to the Special Servicer pursuant to the second
paragraph of Section 3.11(c).

     "Workout Fee Rate": With respect to each Corrected Mortgage Loan, 1.00%.

                                       82
<PAGE>

     "WW Controlling Holder": The majority holder of the most subordinate Class
of WW-1, WW-2 and WW-3 Certificates outstanding for which a Control Change Event
has not occurred with respect to such class.

     "Yield Maintenance Charge": Payments paid or payable, as the context
requires, on a Mortgage Loan as the result of a Principal Prepayment thereon,
not otherwise due thereon in respect of principal or interest, which have been
calculated (based on Scheduled Payments on such Mortgage Loan) to compensate the
holder for reinvestment losses based on the value of an interest rate index at
or near the time of prepayment. Any other prepayment premiums, penalties and
fees not so calculated will not be considered "Yield Maintenance Charges." In
the event that a Yield Maintenance Charge shall become due for any particular
Mortgage Loan, the Master Servicer or the Special Servicer, as applicable, shall
be required to follow the terms and provisions contained in the applicable
Mortgage Note, provided, however, in the event the particular Mortgage Note
shall not specify the U.S. Treasuries which shall be used in determining the
discount rate or the reinvestment yield to be applied in such calculation, the
Master Servicer or the Special Servicer, as applicable, shall be required to use
those U.S. Treasuries having maturity dates most closely approximating the
maturity of such Mortgage Loan. Accordingly if either no U.S. Treasury issue, or
more than one U.S. Treasury issue, shall coincide with the term over which the
Yield Maintenance Charge shall be calculated (which depending on the applicable
Mortgage Note is based on the remaining average life of the Mortgage Loan or the
actual term remaining through the Maturity Date), the Master Servicer or the
Special Servicer, as applicable, shall use the U.S. Treasury whose reinvestment
yield is the lowest, with such yield being based on the bid price for such issue
as published in The Wall Street Journal on the date that is fourteen (14) days
prior to the date that the Yield Maintenance Charge shall become due and payable
(or, if such bid price is not published on that date, the next preceding date on
which such bid price is so published) and converted to a monthly compounded
nominal yield. The monthly compounded nominal yield ("MEY") is derived from the
reinvestment yield or discount rate and shall be defined as MEY = 12X
({(1+"BEY"/2)^1/6}-1) where BEY is defined as the U.S. Treasury Reinvestment
Yield which is in decimal form and not in percentage, and 1/6 is the exponential
power to which a portion of the equation is raised. For example, using a BEY of
5.50%, the MEY = 12 X ({(1+ .055/2)^0.16667}-1) where .055 is the decimal
version of the percentage 5.5% and 0.16667 is the decimal version of the
exponential power. The MEY in the above calculation is 5.44%.

     SECTION 1.02   Certain Adjustments to the Principal Distributions on the
Certificates.

     (a) If any party hereto is reimbursed out of general collections on the
Mortgage Pool on deposit in the Certificate Account for (i) any unreimbursed
Advances that have been or are determined to be Nonrecoverable Advances
(together with interest accrued and payable thereon pursuant to Section 3.03(d),
Section 4.03(d) or Section 4.03(f), as applicable, to the extent such interest
was paid hereunder from a source other than related late payment charges and
Penalty Interest) or (ii) Workout-Delayed Reimbursement Amounts, then (for
purposes of calculating distributions on the Certificates) such reimbursement
and payment of interest shall be deemed to have been made:

                                       83
<PAGE>

          first, out of any amounts then on deposit in the Certificate Account
     that represent payments or other collections of principal received by the
     Trust with respect to the Mortgage Loans in the Loan Group that includes
     the Mortgage Loan or REO Loan in respect of which such Nonrecoverable
     Advance was made or in respect of which the Workout-Delayed Reimbursement
     Amounts are outstanding (exclusive of, unless the subject Nonrecoverable
     Advance or Workout-Delayed Reimbursement Amount relates to the 77 West
     Wacker Drive Mortgage Loan or any successor REO Loan with respect thereto,
     the 77 West Wacker Drive Non-Pooled Portion) that, but for their
     application to reimburse a Nonrecoverable Advance (and/or to pay interest
     thereon) or the Workout-Delayed Reimbursement Amounts, would be included in
     the Available Distribution Amount for the related Distribution Date;

          second, out of any amounts then on deposit in the Certificate Account
     that represent payments or other collections of principal received by the
     Trust with respect to the Mortgage Loans or REO Loans in the Loan Group
     that does not include the Mortgage Loan or REO Loan in respect of which
     such Nonrecoverable Advance was made or Advance in respect of which the
     Workout-Delayed Reimbursement Amounts are outstanding (exclusive of, unless
     the subject Nonrecoverable Advance or Workout-Delayed Reimbursement Amounts
     relate to the 77 West Wacker Drive Mortgage Loan or any successor REO Loan
     with respect thereto, the 77 West Wacker Drive Non-Pooled Portion) that,
     but for their application to reimburse a Nonrecoverable Advance (and/or to
     pay interest thereon) or the Workout-Delayed Reimbursement Amounts, would
     be included in the Available Distribution Amount for the related
     Distribution Date;

          third, out of any amounts then on deposit in the Certificate Account
     that represent payments or other collections of principal received by the
     Trust with respect to the 77 West Wacker Drive Non-Pooled Portion that, but
     for their application to reimburse a Nonrecoverable Advance (and/or to pay
     interest thereon) or the Workout-Delayed Reimbursement Amounts, would be
     included in the 77 West Wacker Drive Available Distribution Amount for the
     related Distribution Date;

          fourth, out of any amounts then on deposit in the Certificate Account
     that represent any other payments or other collections received by the
     Trust with respect to the Mortgage Loans or REO Loans in the Loan Group
     that includes the Mortgage Loan or REO Loan in respect of which such
     Nonrecoverable Advance was made (exclusive of, unless the subject
     Nonrecoverable Advance relates to the 77 West Wacker Drive Mortgage Loan or
     any successor REO Loan with respect thereto, the 77 West Wacker Drive
     Non-Pooled Portion) that, but for their application to reimburse a
     Nonrecoverable Advance and/or to pay interest thereon, would be included in
     the Available Distribution Amount for the related Distribution Date;

          fifth, out of any amounts then on deposit in the Certificate Account
     that represent any other payments or other collections received by the
     Trust with respect to the Mortgage Loans or REO Loans in the Loan Group
     that does not include the Mortgage Loan or REO Loan in respect of which
     such Nonrecoverable Advance was made (exclusive of, unless the subject
     Nonrecoverable Advance relates to the 77 West Wacker Drive Mortgage Loan or
     any successor REO Loan with respect thereto, the 77 West Wacker Drive Non-

     Pooled Portion) that, but for their application to reimburse a
     Nonrecoverable Advance and/or to pay interest thereon, would be included in
     the Available Distribution Amount for the related Distribution Date;

          sixth, out of any amounts then on deposit in the Certificate Account
     that represent any other payments or other collections received by the
     Trust with respect to the 77 West Wacker Drive Non-Pooled Portion that, but
     for their application to reimburse a Nonrecoverable Advance and/or to pay
     interest thereon, would be included in the 77 West Wacker Drive Available
     Distribution Amount for the related Distribution Date; and

          seventh, out of any other amounts then on deposit in the Certificate
     Account that may be available to reimburse the subject Nonrecoverable
     Advance and/or to pay interest thereon.

     (b) If and to the extent that any payment or other collection of principal
of any Mortgage Loan or REO Loan is deemed to be applied in accordance with
clause first, second or third of Section 1.02(a) to reimburse a Nonrecoverable
Advance (or to pay interest thereon) or the Workout-Delayed Reimbursement
Amounts, and further if and to the extent that such payment or other collection
of principal constitutes part of the Principal Distribution Amount for any
Distribution Date, then the Loan Group 1 Principal Distribution Amount and/or
the Loan Group 2 Principal Distribution Amount for such Distribution Date, as
applicable, shall be reduced by the portion, if any, of such payment or other
collection of principal that, but for the application of this clause (b), would
have been included as part of such Loan Group 1 Principal Distribution Amount
and/or the Loan Group 2 Principal Distribution Amount.

     (c) If and to the extent that any Advance is determined to be a
Nonrecoverable Advance or Workout-Delayed Reimbursement Amounts are outstanding,
such Advance or Workout-Delayed Reimbursement Amount is reimbursed out of
general principal collections on the Mortgage Loans as contemplated by Section
1.02(a) above and the particular item for which such Advance was originally made
or such Workout-Delayed Reimbursement Amount is outstanding is subsequently
collected out of payments or other collections in respect of the related
Mortgage Loan or REO Loan (such item, upon collection, a "Recovered Amount"),
then (without duplication of amounts already included therein) the Loan Group 1
Principal Distribution Amount and/or the Loan Group 2 Principal Distribution
Amount for the Distribution Date that corresponds to the Collection Period in
which such item was recovered shall be increased by an amount equal to the
lesser of (A) the amount of such item and (B) any previous reduction in the Loan
Group 1 Principal Distribution Amount and/or the Loan Group 2 Principal
Distribution Amount, as applicable, for a prior Distribution Date pursuant to
Section 1.02 (b) above resulting from the reimbursement of the subject Advance
(and/or the payment of interest thereon) or Workout-Delayed Reimbursement
Amounts.

     (d) If, and to the extent that, any payment or other collection of
principal of any Mortgage Loan or REO Loan is deemed to be applied in accordance
with clause third of Section 1.02(a) to reimburse a Nonrecoverable Advance (or
to pay interest thereon) or Workout-Delayed Reimbursement Amounts, then the 77
West Wacker Drive Principal Distribution Amount for such Distribution Date
distributable to the holders of the Class WW Principal Balance Certificates
shall be reduced by the portion, if any, of such payment or other collection of
principal that, but for the application of this clause (d), would have been
included as part of such portion of the 77 West Wacker Drive Principal
Distribution Amount.

                                       85
<PAGE>

     (e) For purposes of making the adjustments to the Loan Group 1 Principal
Distribution Amount, the Loan Group 2 Principal Distribution Amount and the 77
West Wacker Drive Principal Distribution Amount, respectively, for each
Distribution Date contemplated by this Section 1.02, each of those amounts shall
be calculated in accordance with the respective definitions thereof (without
regard to this Section 1.02) and shall thereafter be adjusted as provided in
this Section 1.02.

     (f) If and to the extent that any payments or other collections with
respect to the 77 West Wacker Drive Mortgage Loan or any successor REO Loan with
respect thereto that would otherwise have constituted part of the 77 West Wacker
Drive Available Distribution Amount for any Distribution Date and been
distributed on the Class WW Certificates are deemed applied to the reimbursement
(with interest) of a Nonrecoverable Advance or a Workout-Delayed Reimbursement
Amount that relates to any other Mortgage Loan or REO Loan, the Trustee shall,
on each subsequent Distribution Date, after the distributions contemplated by
Section 4.01(k) or 4.01(l), as applicable, and prior to the distributions
contemplated by Section 4.01(a), withdraw from the Distribution Account and
apply to make distributions on the Class WW Certificates in accordance with
clauses (iv) through (xii) of Section 4.01(k) or 4.01(l), as applicable, amounts
otherwise distributable on such subsequent Distribution Date with respect to the
Certificates (other than the Class WW Certificates) pursuant to Section 4.01(a),
until such payments and other collections diverted from the Class WW
Certificates have been fully offset; provided that, notwithstanding Section
1.02(d) or any other provision hereof, principal that would otherwise have been
payable to any Class of Class WW Principal Balance Certificates but for such
diversion of funds shall remain due and owing for purposes of the distributions
pursuant to this Section 1.02(f) until paid in full; and provided, further,
that, insofar as payments with respect to the Class WW Certificates pursuant to
this Section 1.02(f) are intended to make distributions of principal on the
Class WW Certificates that would have otherwise been distributable on a prior
Distribution Date, but for the diversion of payments and/or other collections of
principal with respect to the 77 West Wacker Drive Mortgage Loan or any
successor REO Loan with respect thereto from distributions on the Class WW
Principal Balance Certificates to the reimbursement (with interest) of
Nonrecoverable Advances in respect of other Mortgage Loans and/or REO Loans, the
amounts to be withdrawn from the Distribution Account and distributed on the
Class WW Certificates pursuant to this Section 1.02(f) shall be limited to
payments and other collections of principal on the Mortgage Loans and/or REO
Loans that would otherwise be part of the Principal Distribution Amount for

                                       86
<PAGE>

the subject Distribution Date (with a corresponding reduction in such Principal
Distribution Amount as if such payment or other collection of principal were
going to reimburse the Nonrecoverable Advance and/or Workout-Delayed
Reimbursement Amounts that originally gave rise to the diversion of funds from
the Class WW Certificates). Conversely, the portion of the 77 West Wacker Drive
Available Distribution Amount for any Distribution Date that is attributable to
the 77 West Wacker Drive Non-Pooled Portion or the non-pooled portion of any
successor REO Loan with respect thereto shall be deemed reduced to the extent
necessary to offset any payments or other collections with respect to other
Mortgage Loans or REO Loans that were previously deemed applied to the
reimbursement (with interest) of any Nonrecoverable Advance and/or
Workout-Delayed Reimbursement Amounts that relates to the 77 West Wacker Drive
Mortgage Loan or any successor REO Loan with respect thereto.

     (g) Nothing contained in this Section 1.02 is intended to limit the ability
of any party hereto that is entitled to reimbursement hereunder for any
unreimbursed Advances that have been or are determined to be Nonrecoverable
Advances (together with interest accrued and payable thereon pursuant to Section
3.03(d) or Section 4.03(d)) to collections of principal received by the Trust
with respect to the Mortgage Pool; instead the order of priority set forth in
Section 1.02(a) is a deemed allocation only for purposes of calculating
distributions on the Certificates.

     SECTION 1.03   Certain Calculations in Respect of the Mortgage Pool.

     All amounts collected by or on behalf of the Trust in respect of any Loan
Pair (including the Fairfield Commons Total Loan unless the Fairfield Commons
Pari Passu Companion Loan is being serviced under the Series 2003-C5 Pooling and
Servicing Agreement), including any payments from Mortgagors Insurance Proceeds,
condemnation proceeds and Liquidation Proceeds, shall be applied between the
related Pooled Mortgage Loan and Companion Loan in accordance with the express
provisions of the related Intercreditor Agreement.

                                   ARTICLE II

                CONVEYANCE OF MORTGAGE LOANS; REPRESENTATIONS AND
                 WARRANTIES; ORIGINAL ISSUANCE OF CERTIFICATES

     SECTION 2.01   Conveyance of Mortgage Loans.

     (a) The Depositor, concurrently with the execution and delivery hereof,
does hereby establish a common law trust under the laws of the State of New
York, designated as "MLMT Commercial Mortgage Trust 2003-KEY1" and consisting of
the Trust Fund, and does hereby assign, sell, transfer, set over and otherwise
convey to the Trustee, in trust, without recourse, for the benefit of the
Certificateholders (and for the benefit of the other parties to this Agreement
as their respective interests may appear) all the right, title and interest of
the Depositor, in, to and under (i) the Mortgage Loans and all documents
included in the related Mortgage Files and Servicing Files, (ii) the rights of
the Depositor under Sections 2, 3, 8, 9, 10, 11, 12, 13, 14, 16, 17, 18, 19 and
20 of each of the Merrill Mortgage Loan Purchase Agreement, KeyBank Mortgage
Loan Purchase Agreement and the JPMorgan Mortgage Loan Purchase Agreement and
(iii) all other assets included or to be included in the Trust Fund. Such
assignment includes all interest and principal received or receivable on or with
respect to the

                                       87
<PAGE>

Mortgage Loans and due after the Cut-off Date. The transfer of the Mortgage
Loans and the related rights and property accomplished hereby is absolute and,
notwithstanding Section 11.07, is intended by the parties to constitute a sale.

     (b) In connection with the Depositor's assignment pursuant to Section
2.01(a) above the Depositor shall direct, and hereby represents and warrants
that it has directed, the Mortgage Loan Sellers pursuant to the Merrill Mortgage
Loan Purchase Agreement, the KeyBank Mortgage Loan Purchase Agreement and the
JPMorgan Mortgage Loan Purchase Agreement, as applicable, to deliver to and
deposit with, or cause to be delivered to and deposited with, the Trustee or a
Custodian appointed thereby (with a copy to the Master Servicer and Special
Servicer), on or before the Closing Date, the Mortgage File for each Mortgage
Loan so assigned. The Special Servicer may request the Master Servicer to
deliver a copy of the Servicing File for any Mortgage Loan (other than a
Specially Serviced Mortgage Loan). None of the Trustee, the Fiscal Agent, any
Custodian, the Master Servicer or the Special Servicer shall be liable for any
failure by any Mortgage Loan Seller or the Depositor to comply with the document
delivery requirements of the Merrill Mortgage Loan Purchase Agreement, the
KeyBank Mortgage Loan Purchase Agreement, the JPMorgan Mortgage Loan Purchase
Agreement and this Section 2.01(b).

     (c) If any Mortgage Loan Seller cannot deliver, or cause to be delivered,
on the Closing Date, as to any Mortgage Loan, any of the documents and/or
instruments referred to in clauses (ii), (iii), (vi) (if recorded) and (viii) of
the definition of "Mortgage File", with evidence of recording thereon, solely
because of a delay caused by the public recording office where such document or
instrument has been delivered for recordation, the delivery requirements of the
Merrill Mortgage Loan Purchase Agreement, the KeyBank Mortgage Loan Purchase
Agreement or the JPMorgan Mortgage Loan Purchase Agreement, as applicable, and
Section 2.01(b) shall be deemed to have been satisfied as to such non-delivered
document or instrument, and such non-delivered document or instrument shall be
deemed to have been included in the Mortgage File, provided that a photocopy of
such non-delivered document or instrument (certified by the applicable Mortgage
Loan Seller to be a true and complete copy of the original thereof submitted for
recording) is delivered to the Trustee or a Custodian appointed thereby on or
before the Closing Date, and either the original of such non-delivered document
or instrument, or a photocopy thereof, with evidence of recording thereon, is
delivered to the Trustee or such Custodian within 120 days of the Closing Date
(or within such longer period after the Closing Date as the Trustee may consent
to, which consent shall not be unreasonably withheld so long as the applicable
Mortgage Loan Seller is, in good faith, attempting to obtain from the
appropriate county recorder's office such original or photocopy, as evidenced by
an officer's certificate). If the applicable Mortgage Loan Seller cannot
deliver, or cause to be delivered, as to any Mortgage Loan, any of the documents
and/or instruments referred to in clauses (ii), (iii), (vi) (if recorded) and
(viii) of the definition of "Mortgage File," with evidence of recording thereon,
for any other reason, including, without limitation, that such non-delivered
document or instrument has been lost, the delivery requirements of the Merrill
Mortgage Loan Purchase Agreement, the KeyBank Mortgage Loan Purchase Agreement
or the JPMorgan Mortgage Loan Purchase Agreement, as applicable, and Section
2.01(b) shall be deemed to have been satisfied as to such non-delivered document
or instrument and such non-delivered document or instrument shall be deemed to
have been included in the Mortgage File, provided that a photocopy of such
non-delivered document or instrument (with evidence of recording in the proper
office thereon and with respect to item

                                       88
<PAGE>

(ii), certified by the appropriate county recorder's office to be a true and
complete copy of the original submitted for recording) is delivered to the
Trustee or a Custodian appointed thereby on or before the Closing Date.

     If, on the Closing Date as to any Mortgage Loan, the applicable Mortgage
Loan Seller does not deliver in complete and recordable form any one of the
assignments in favor of the Trustee referred to in clause (iv) or (v) of the
definition of "Mortgage File" (in the case of clause (iv) solely because of a
delay caused by the recording office where such document or instrument has been
delivered for recordation), the applicable Mortgage Loan Seller may
provisionally satisfy the delivery requirements of the related Merrill Mortgage
Loan Purchase Agreement, KeyBank Mortgage Loan Purchase Agreement or JPMorgan
Mortgage Loan Purchase Agreement, as applicable, and Section 2.01(b) by
delivering with respect to such Mortgage Loan on the Closing Date an omnibus
assignment of such Mortgage Loan; provided that all required original
assignments with respect to such Mortgage Loan in fully complete and recordable
form shall be delivered to the Trustee or its Custodian within 120 days of the
Closing Date (or within such longer period, not to exceed 18 months, as the
Trustee in its reasonable discretion may permit so long as the applicable
Mortgage Loan Seller is, as certified in writing to the Trustee no less often
than every 90 days, attempting in good faith to obtain from the appropriate
county recorder's office such original or photocopy).

     (d) With respect to the Mortgage Loans the Trustee shall, for a fee paid to
the Trustee by the Depositor on the Closing Date as to each Mortgage Loan,
promptly (and in any event within 90 days following the later of the Closing
Date or the delivery of all assignments and UCC Financing Statements to the
Trustee) cause to be submitted for recording or filing, as the case may be, in
the appropriate public office for real property records or UCC Financing
Statements, as appropriate and to the extent timely delivered to the Trustee in
final, recordable form, each assignment of Mortgage, assignment of Assignment of
Leases and, to the extent the Trustee has actual knowledge that such documents
are to be recorded, any other recordable documents relating to each such
Mortgage Loan, in favor of the Trustee referred to in clause (iv) of the
definition of "Mortgage File" and each UCC-2 and UCC-3 assignment in favor of
the Trustee and so delivered to the Trustee and referred to in clause (viii) of
the definition of "Mortgage File." Each such assignment, UCC-2 and UCC-3 shall
reflect that the recorded original should be returned by the public recording
office to the Trustee or its designee following recording, and each such UCC-2
and UCC-3 assignment shall reflect that the file copy thereof should be returned
to the Trustee or its designee following filing; provided, that in those
instances where the public recording office retains the original assignment of
Mortgage or assignment of Assignment of Leases, the Trustee shall obtain
therefrom a certified copy of the recorded original, at the expense of the
Depositor. If any such document or instrument is lost or returned unrecorded or
unfiled, as the case may be, because of a defect therein, the Trustee shall
direct the related Mortgage Loan Seller pursuant to the Merrill Mortgage Loan
Purchase Agreement, the KeyBank Mortgage Loan Purchase Agreement or the JPMorgan
Mortgage Loan Purchase Agreement, as applicable, to promptly prepare or cause to
be prepared a substitute therefor or cure such defect, as the case may be, and
thereafter the Trustee shall upon receipt thereof cause the same to be duly
recorded or filed, as appropriate. Upon request, the Trustee shall forward to
the Master Servicer a copy of each of the aforementioned recorded assignments
following the Trustee's receipt thereof, to the extent not previously provided.

                                       89
<PAGE>

     (e) All documents and records in the Servicing File (except attorney-client
privileged communications, internal correspondence and credit analysis of the
Mortgage Loan Seller) in possession of the Depositor or the Mortgage Loan
Sellers that relate to the Mortgage Loans and that are not required to be a part
of a Mortgage File in accordance with the definition thereof (including any
original letters of credit), together with all Escrow Payments and Reserve
Accounts in the possession thereof, shall be delivered to the Master Servicer or
such other Person as may be directed by the Master Servicer (at the expense of
the applicable Mortgage Loan Seller) on or before the Closing Date and shall be
held by the Master Servicer on behalf of the Trustee in trust for the benefit of
the Certificateholders; provided, however, the Master Servicer shall have no
responsibility for holding documents created or maintained by the Special
Servicer hereunder and not delivered to the Master Servicer. The applicable
Mortgage Loan Seller shall pay any costs of assignment or amendment of any
letter of credit related to the Mortgage Loans such Mortgage Loan Seller sold to
the Depositor required in order for the Master Servicer to draw on such letter
of credit.

     (f) In connection with the Depositor's assignment pursuant to Section
2.01(a) above, the Depositor shall deliver to the Custodian, the Master Servicer
and the Special Servicer on or before the Closing Date and hereby represents and
warrants that it has delivered a copy of a fully executed counterpart of each of
the Merrill Mortgage Loan Purchase Agreement, the KeyBank Mortgage Loan Purchase
Agreement and the JPMorgan Mortgage Loan Purchase Agreement, as in full force
and effect on the Closing Date.

     (g) The Depositor hereby consents to the filing of any financial statements
contemplated by this Agreement without its consent.

     SECTION 2.02   Acceptance of the Trust Fund by Trustee.

     (a) The Trustee, by its execution and delivery of this Agreement,
acknowledges receipt of the Depositor's assignment to it of the Depositor's
right, title and interest in the assets that constitute the Trust Fund, and
further acknowledges receipt by it or a Custodian on its behalf, subject to the
provisos in the definition of "Mortgage File" and the provisions of Section 2.01
and subject to the further limitations on review provided for in Section 2.02(b)
and the exceptions noted on the schedule of exceptions of (i) the Mortgage File
delivered to it for each Mortgage Loan and (ii) a copy of a fully executed
counterpart of each of the Merrill Mortgage Loan Purchase Agreement, the KeyBank
Mortgage Loan Purchase Agreement and the JPMorgan Mortgage Loan Purchase
Agreement, all in good faith and without notice of any adverse claim, and
declares that it or a Custodian on its behalf holds and will hold such documents
and the other documents received by it that constitute portions of the Mortgage
Files, and that it holds and will hold the Mortgage Loans and other assets
included in the Trust Fund, in trust for the exclusive use and benefit of all
present and future Certificateholders and, with respect to any original document
in the Mortgage File for any Loan Pair, any present or future Companion Holder.
The Trustee hereby certifies to each of the Depositor, the Master Servicer, the
Special Servicer and each Mortgage Loan Seller that except as identified in the
schedule of exceptions, which is attached hereto as Exhibit C-1 without regard
to the proviso in the definition of "Mortgage File", each of the original
executed Mortgage Notes as described in clause (i) of the definition of Mortgage
File are in its possession. In addition, within ninety (90) days after the
Closing Date (and if any exceptions are noted, again every 90 days thereafter
until the second anniversary of

                                       90
<PAGE>

the Closing Date, and every 180 days thereafter until the fifth anniversary of
the Closing Date, and thereafter upon request by any party hereto, any Mortgage
Loan Seller or the Majority Subordinate Certificateholder), the Trustee or the
Custodian on its behalf will review the Mortgage Files and certify (in a
certificate substantially in the form of Exhibit C-2) to each of the Depositor,
the Master Servicer, the Special Servicer and each Mortgage Loan Seller (with
copies to the Majority Subordinate Certificateholder) that, with respect to each
Mortgage Loan (other than with respect to the Companion Loans) listed in the
Mortgage Loan Schedule, except as specifically identified in the schedule of
exceptions annexed thereto, (i) without regard to the proviso in the definition
of "Mortgage File," all documents specified in clauses (i), (ii), (iv)(a), (v)
and (vii), and to the extent provided in the related Mortgage File and actually
known by a Responsible Officer of the Trustee to be required or to the extent
listed on the Mortgage Loan checklist provided as part of the Mortgage File,
clauses (iii), (iv)(b), (iv)(c), (vi), (viii) and (xi) of the definition of
"Mortgage File" are in its possession, (ii) all documents delivered or caused to
be delivered by the applicable Mortgage Loan Seller constituting the related
Mortgage File have been reviewed by it and appear regular on their face, appear
to be executed and appear to relate to such Mortgage Loan, (iii) based on such
examination and only as to the foregoing documents, the information set forth in
the Mortgage Loan Schedule for such Mortgage Loan with respect to the items
specified in clauses (v) and (vi)(c) of the definition of "Mortgage Loan
Schedule" is correct and (iv) solely with respect to the Companion Loans, all
documents specified in clause (xii) of the definition of "Mortgage File" are in
its possession. Further, with respect to the documents described in clause
(viii) of the definition of Mortgage File, absent actual knowledge to the
contrary or copies of UCC Financing Statements delivered to the Trustee as part
of the Mortgage File indicating otherwise, the Trustee may assume, for purposes
of the certification delivered in this Section 2.02(a), that the related
Mortgage File should include one state level UCC Financing Statement filing and
one local UCC Financing Statement fixture filing for each Mortgaged Property (or
with respect to any Mortgage Loan that has two or more Mortgagors, for each
Mortgagor). Amendments with respect to the UCC Financing Statements to be
assigned to the Trust, assigning such UCC Financing Statements to the Trust,
will be delivered on the new national forms and in recordable form and will be
filed in the state of incorporation or organization of the related Mortgagor as
so indicated on the documents provided.

     (b) None of the Trustee, the Fiscal Agent, the Master Servicer, the Special
Servicer or any Custodian is under any duty or obligation to inspect, review or
examine any of the documents, instruments, certificates or other papers relating
to the Mortgage Loans delivered to it to determine that the same are valid,
legal, effective, genuine, enforceable, in recordable form, sufficient or
appropriate for the represented purpose or that they are other than what they
purport to be on their face.

(c) With respect to the Fairfield Commons Total Loan, upon receiving notice that
the Fairfield Commons Pari Passu Companion Loan is being included in the Series
2003-C5 Securitization, the Trustee shall deliver the related Mortgage File
exclusive of the original Mortgage Note for the Fairfield Commons Pooled
Mortgage Loan (and retain a copy thereof) to the Series 2003-C5 Trustee, as
directed by the Master Servicer in a timely fashion to allow KeyBank to meet any
deadlines for delivery of such documents in connection with the Series 2003-C5
Securitization. If after the Fairfield Commons Pari Passu Companion Loan has
been included in the Series 2003-C5 Securitization it is removed therefrom, the
Master Servicer shall obtain from the holder of the Fairfield Commons Pari Passu
Companion Loan the documents and

                                       91
<PAGE>

instruments necessary to perform servicing and administration of the Fairfield
Commons Total Loan and shall deliver to the Trustee any such documents or
instruments that are required to be included in the Mortgage File with respect
to the Fairfield Commons Pari Passu Companion Loan as a Companion Loan under
this Agreement.

     SECTION 2.03   Mortgage Loan Seller's Repurchase or Substitution of
Mortgage Loans for Document Defects and Breaches of Representations and
Warranties.

     (a) If any party hereto discovers (without implying any duty of such Person
to make any inquiry) or receives notice that any document or documents
constituting a part of a Mortgage File has not been properly executed, is
missing (beyond the time period required for its delivery hereunder), contains
information that does not conform in any material respect with the corresponding
information set forth in the Mortgage Loan Schedule, or does not appear to be
regular on its face (each, a "Document Defect"), or discovers (without implying
any duty of such Person to make any inquiry) or receives notice of a breach of
any representation or warranty relating to any Mortgage Loan set forth in the
Merrill Mortgage Loan Purchase Agreement, the KeyBank Mortgage Loan Purchase
Agreement or the JPMorgan Mortgage Loan Purchase Agreement (a "Breach"), the
party discovering such Document Defect or Breach shall give written notice
(which notice, in respect of any obligation of the Trustee to provide notice of
a Document Defect, shall be deemed given by the delivery of the certificate as
required by Section 2.02(a)) to the applicable Mortgage Loan Seller and the
other parties hereto. The Trustee shall then promptly deliver such notice to the
Majority Subordinate Certificateholder (and in the case of the 77 West Wacker
Drive Mortgage Loan, the WW Controlling Holder) and to the Rating Agencies of
such Document Defect or Breach. Promptly upon becoming aware of any Document
Defect or Breach (including through such written notice provided by any party
hereto or the Majority Subordinate Certificateholder as provided above), if any
party hereto determines that such Document Defect or Breach materially and
adversely affects the interests of the Certificateholders or the value of the
affected Mortgage Loan such party shall notify the Master Servicer and, if the
subject Mortgage Loan is a Specially Serviced Mortgage Loan, the Special
Servicer, of such determination and promptly after receipt of such notice, the
Master Servicer or the Special Servicer, as applicable, shall request in writing
that the applicable Mortgage Loan Seller, not later than ninety (90) days from
receipt of such written request (or, in the case of a Document Defect or Breach
relating to a Mortgage Loan not being a "qualified mortgage" within the meaning
of the REMIC Provisions, not later than ninety (90) days after any party to this
Agreement discovers such Document Defect or Breach) (i) cure such Document
Defect or Breach, as the case may be, in accordance with Section 3(c) of the
Merrill Mortgage Loan Purchase Agreement, the KeyBank Mortgage Loan Purchase
Agreement or the JPMorgan Mortgage Loan Purchase Agreement, as applicable, (ii)
repurchase the affected Mortgage Loan (which for purposes of this clause (ii)
shall include an REO Loan) in accordance with Section 3(c) of the Merrill
Mortgage Loan Purchase Agreement, the KeyBank Mortgage Loan Purchase Agreement
or the JPMorgan Mortgage Loan Purchase Agreement, or (iii) within two years of
the Closing Date, substitute a Qualified Substitute Mortgage Loan for such
affected Mortgage Loan (which for purposes of this clause (iii) shall include an
REO Loan) and pay the Master Servicer for deposit into the Certificate Account
any Substitution Shortfall Amount in connection therewith in accordance with
Sections 3(c) and 3(d) of the Merrill Mortgage Loan Purchase Agreement, the
KeyBank Mortgage Loan Purchase Agreement or the JPMorgan Mortgage Loan Purchase
Agreement; provided, however, that if such Document Defect or Breach is capable
of

                                       92
<PAGE>

being cured but not within such ninety (90) day period, such Document Defect or
Breach does not relate to the Mortgage Loan not being treated as a "qualified
mortgage" within the meaning of the REMIC Provisions, and the applicable
Mortgage Loan Seller has commenced and is diligently proceeding with the cure of
such Document Defect or Breach within such ninety (90) day period, the
applicable Mortgage Loan Seller shall have an additional ninety (90) days to
complete such cure (or, failing such cure, to repurchase the related Mortgage
Loan (which for purposes of such repurchase shall include an REO Loan); and
provided, further, with respect to such additional ninety (90) day period the
applicable Mortgage Loan Seller shall have delivered an Officer's Certificate to
the Trustee setting forth the reasons such Document Defect or Breach is not
capable of being cured within the initial ninety (90) day period and what
actions the applicable Mortgage Loan Seller is pursuing in connection with the
cure thereof and stating that the applicable Mortgage Loan Seller anticipates
such Document Defect or Breach will be cured within the additional ninety (90)
day period; and provided, further, that no Document Defect (other than with
respect to a Mortgage Note, Mortgage, title insurance policy, Ground Lease, any
intervening assignment required to create a complete assignment to the Trustee
or any letter of credit) shall be considered to materially and adversely affect
the interests of the Certificateholders or the value of the related Mortgage
Loan unless the document with respect to which the Document Defect exists is
required in connection with an imminent enforcement of the mortgagee's rights or
remedies under the related Mortgage Loan, defending any claim asserted by any
borrower or third party with respect to the Mortgage Loan, establishing the
validity or priority of any lien on any collateral securing the Mortgage Loan or
for any immediate servicing obligations. In the event of a Document Defect or
Breach as to a Mortgage Loan that is cross-collateralized and cross-defaulted
with one or more other Mortgage Loans (each a "Crossed Loan" and, collectively,
a "Crossed Group"), and such Document Defect or Breach does not constitute a
Document Defect or Breach, as the case may be, as to any other Crossed Loan in
such Crossed Group (without regard to this paragraph) and is not cured as
provided for above then the applicable Document Defect or Breach, as the case
may be, shall be deemed to constitute a Document Defect or Breach, as the case
may be, as to any other Crossed Loan in the Crossed Group for purposes of this
paragraph and the related Mortgage Loan Seller shall be required to repurchase
or substitute all such cross-collateralized and cross-defaulted Mortgage Loans
unless (1) the Debt Service Coverage Ratio for all the remaining related Crossed
Loans for the four calendar quarters immediately preceding such repurchase or
substitution is not less than the greater of the Debt Service Coverage Ratio for
all such related Crossed Loans including the affected Crossed Loan, for the four
calendar quarters immediately preceding such repurchase or substitution and
1.25x, (2) the weighted average Loan-to-Value Ratio for the remaining related
Crossed Loans determined at the time of repurchase or substitution based upon an
Appraisal obtained by the Special Servicer at the expense of the related
Mortgage Loan Seller shall not be greater than the lesser of (a) the weighted
average Loan-to-Value Ratio for all such related Crossed Loans, including the
affected Crossed Loan and (b) 75%; provided, that if such criteria is satisfied
and any Crossed Loan is not so repurchased or substituted, then such Crossed
Loan shall be released from its cross-collateralization and cross default
provision so long as such Crossed Loan is held in the Trust Fund, provided,
further, that the repurchase of less than all such Crossed Loans and the release
from cross-collateralization and cross-default provision shall be subject to the
delivery by the Mortgage Loan Seller to the Trustee, at the expense of the
Mortgage Loan Seller, of an Opinion of Counsel to the effect that such release
would not cause 77 West Wacker Drive Loan REMIC,

                                       93
<PAGE>

REMIC I or REMIC II to fail to qualify as a REMIC under the Code or result in
the imposition of any tax on "prohibited transactions" or "contributions" after
the Startup Day under the REMIC Provisions, and provided, further, that the
borrower under such Mortgage Loan is an intended third party beneficiary of this
provision, which shall not be modified without such borrower's consent; and
provided further, that the Majority Subordinate Certificateholder shall have
consented to the repurchase of the affected Crossed Loan, which consent shall
not be unreasonably withheld. In the event that one or more of such other
Crossed Loans satisfy the aforementioned criteria, the related Mortgage Loan
Seller may elect either to repurchase or substitute for only the affected
Crossed Loan as to which the related Document Defect or Breach exists or to
repurchase or substitute for all of the Crossed Loans in the related Crossed
Group. All documentation relating to the termination of the
cross-collateralization provisions of each Crossed Loan being repurchased is to
be prepared at the expense of the applicable Mortgage Loan Seller and, where
required, with the consent of the applicable Mortgagor. For a period of two
years from the Closing Date, so long as there remains any Mortgage File as to
which there is any uncured Document Defect and so long as the applicable
Mortgage Loan Seller shall provide the Officer's Certificate pursuant to Section
3(c) of the Merrill Mortgage Loan Purchase Agreement, the KeyBank Mortgage Loan
Purchase Agreement or the JPMorgan Mortgage Loan Purchase Agreement, the Trustee
shall on a quarterly basis prepare and deliver electronically to the other
parties a written report as to the status of such uncured Document Defects as
provided in Section 2.02(a). If the affected Mortgage Loan is to be repurchased
or substituted, the Master Servicer shall designate the Certificate Account as
the account to which funds in the amount of the Purchase Price or the
Substitution Shortfall Amount, as applicable, are to be wired. Any such
repurchase or substitution of a Mortgage Loan shall be on a whole loan,
servicing released basis.

     (b) In connection with any repurchase or substitution of one or more
Mortgage Loans contemplated by this Section 2.03, upon receipt of a Request for
Release (in the form of Exhibit D-1 attached hereto) of a Servicing Officer of
the Master Servicer certifying as to the receipt of the applicable Purchase
Price(s) in the Certificate Account (in the case of any such repurchase) or the
receipt of the applicable Substitution Shortfall Amount(s) in the Certificate
Account and upon the delivery of the Mortgage File(s) and the Servicing File(s)
for the related Qualified Substitute Mortgage Loan(s) to the Custodian and the
Master Servicer, respectively (in the case of any such substitution), (i) the
Trustee shall execute and deliver such endorsements and assignments as are
provided to it, in each case without recourse, representation or warranty, as
shall be necessary to vest in the applicable Mortgage Loan Seller the legal and
beneficial ownership of each repurchased Mortgage Loan or deleted Mortgage Loan,
as applicable, being released pursuant to this Section 2.03, and (ii) the
Trustee, the Custodian, the Master Servicer, and the Special Servicer shall each
tender to the applicable Mortgage Loan Seller, upon delivery to each of them of
a receipt executed by the applicable Mortgage Loan Seller, all portions of the
Mortgage File and other documents pertaining to each such Mortgage Loan
possessed by it and the Master Servicer and the Special Servicer shall release
to the applicable Mortgage Loan Seller any Escrow Payments and Reserve Funds
held by it in respect of such repurchased or deleted Mortgage Loan; provided,
that such tender by the Trustee or the Custodian shall be conditioned upon its
receipt from the Master Servicer or the Special Servicer of a Request for
Release. Thereafter, the Trustee, the Fiscal Agent, the Custodian, the Master
Servicer and the Special Servicer shall have no further responsibility with
regard to the related repurchased Mortgage Loan(s) or deleted Mortgage Loan(s),
as applicable, and the related Mortgage File(s) and

                                       94
<PAGE>

Servicing File(s). The Master Servicer shall, and is hereby authorized and
empowered by the Trustee to, prepare, execute and deliver in its own name, on
behalf of the Certificateholders and the Trustee or any of them, the
endorsements and assignments contemplated by this Section 2.03, and the Trustee
shall execute any powers of attorney that are prepared and delivered to the
Trustee by the Master Servicer to permit the Master Servicer to do so. The
Master Servicer shall indemnify the Trustee for any reasonable costs, fees,
liabilities and expenses incurred by the Trustee in connection with the
negligent or willful misuse by the Master Servicer of such powers of attorney.
At the time a substitution is made, the Merrill Mortgage Loan Purchase
Agreement, the KeyBank Mortgage Loan Purchase Agreement or the JPMorgan Mortgage
Loan Purchase Agreement, as applicable, will provide that the applicable
Mortgage Loan Seller shall deliver the related Mortgage File to the Trustee and
certify that the substitute Mortgage Loan is a Qualified Substitute Mortgage
Loan.

     (c) No substitution of a Qualified Substitute Mortgage Loan or Loans may be
made in any calendar month after the Determination Date for such month. Periodic
Payments due with respect to any Qualified Substitute Mortgage Loan after the
related date of substitution shall be part of 77 West Wacker Drive Loan REMIC or
REMIC I, as applicable. No substitution of a Qualified Substitute Mortgage Loan
for a deleted Mortgage Loan shall be permitted under this Agreement if after
such substitution, the aggregate of the Stated Principal Balances of all
Qualified Substitute Mortgage Loans which have been substituted for deleted
Mortgage Loans exceeds 10% of the aggregate Cut-off Date Balance of all the
Mortgage Loans. Periodic Payments due with respect to any Qualified Substitute
Mortgage Loan on or prior to the related date of substitution shall not be part
of the Trust Fund, 77 West Wacker Drive Loan REMIC, or REMIC I and will (to the
extent received by the Master Servicer) be remitted by the Master Servicer to
the applicable Mortgage Loan Seller promptly following receipt.

     (d) The Merrill Mortgage Loan Purchase Agreement, the KeyBank Mortgage Loan
Purchase Agreement, the JPMorgan Mortgage Loan Purchase Agreement and Section
2.03(a) of this Agreement provide the sole remedies available to the
Certificateholders, or the Trustee on behalf of the Certificateholders,
respecting any Document Defect or Breach with respect to the Mortgage Loans
purchased by the Depositor thereunder.

     (e) The Trustee with the cooperation of the Special Servicer (in the case
of Specially Serviced Mortgage Loans) shall, for the benefit of the
Certificateholders, enforce the obligations of the Mortgage Loan Sellers under
Section 3 of the Merrill Mortgage Loan Purchase Agreement, the KeyBank Mortgage
Loan Purchase Agreement and the JPMorgan Mortgage Loan Purchase Agreement.

     Notwithstanding anything contained herein or the related Mortgage Loan
Purchase Agreement, no delay in the discovery of a Defect or Breach or delay on
the part of any party to this Agreement in providing notice of such Defect or
Breach shall relieve the related Mortgage Loan Seller of its obligations to
repurchase or substitute if it is otherwise required to do so under the related
Mortgage Loan Purchase Agreement.

     If the applicable Mortgage Loan Seller incurs any expense in connection
with the curing of a Document Defect or a Breach which also constitutes a
default under the related Mortgage Loan and is reimbursable thereunder, such
Mortgage Loan Seller shall have a right,

                                       95
<PAGE>

and shall be subrogated to the rights of the Trustee and the Trust Fund, as
successor to the mortgagee, to recover the amount of such expenses from the
related Mortgagor; provided, however, that such Mortgage Loan Seller's rights
pursuant to this paragraph shall be junior, subject and subordinate to the
rights of the Master Servicer, the Special Servicer, the Trustee, the Fiscal
Agent and the Trust Fund to recover amounts owed by the related Mortgagor under
the terms of such Mortgage Loan, including the rights to recover unreimbursed
Advances, accrued and unpaid interest on Advances at the Reimbursement Rate and
unpaid or unreimbursed expenses of the Trustee, the Fiscal Agent, the Trust
Fund, the Master Servicer or the Special Servicer allocable to such Mortgage
Loan. The Master Servicer or, with respect to a Specially Serviced Mortgage
Loan, the Special Servicer, shall use reasonable efforts to recover such
expenses for such Mortgage Loan Seller to the extent consistent with the
Servicing Standard, but taking into account the subordinate nature of the
reimbursement to the Mortgage Loan Seller; provided, however, that the Master
Servicer or, with respect to a Specially Serviced Mortgage Loan, the Special
Servicer determines in the exercise of its sole discretion consistent with the
Servicing Standard that such actions by it will not impair the Master Servicer's
and/or the Special Servicer's collection or recovery of principal, interest and
other sums due with respect to the related Mortgage Loan which would otherwise
be payable to the Master Servicer, the Special Servicer, the Trustee, the Fiscal
Agent and the Certificateholders pursuant to the terms of this Agreement.

     SECTION 2.04   Representations and Warranties of Depositor.

     (a) The Depositor hereby represents and warrants to the Trustee, for its

     and the performance and compliance with the terms of this Agreement by the
     Depositor, will not violate the Depositor's certificate of incorporation or
     bylaws or constitute a default (or an event which, with notice or lapse of
     time, or both, would constitute a default) under, or result in the breach
     of, any material agreement or other instrument to which it is a party or
     which is applicable to it or any of its assets.

          (iii) The Depositor has the full power and authority to enter into and
     consummate all transactions contemplated by this Agreement, has duly

     delivery by each of the other parties hereto, constitutes a valid, legal
     and binding obligation of the Depositor, enforceable against the Depositor
     in accordance with the terms hereof, subject to (A) applicable bankruptcy,
     insolvency, reorganization, moratorium and other laws affecting the
     enforcement of creditors' rights generally, and

                                       96
<PAGE>

     (B) general principles of equity, regardless of whether such enforcement is
     considered in a proceeding in equity or at law.

          (v) The Depositor is not in violation of, and its execution and
     delivery of this Agreement and its performance and compliance with the
     terms of this Agreement will not constitute a violation of, any law, any
     order or decree of any court or arbiter, or any order, regulation or demand
     of any federal, state or local governmental or regulatory authority, which
     violation, in the Depositor's good faith and reasonable judgment, is likely
     to affect materially and adversely either the ability of the Depositor to
     perform its obligations under this Agreement or the financial condition of
     the Depositor.

          (vi) The transfer of the Mortgage Loans to the Trustee as contemplated
     herein requires no regulatory approval, other than any such approvals as
     have been obtained, and is not subject to any bulk transfer or similar law
     in effect in any applicable jurisdiction.

          (vii) No litigation is pending or, to the best of the Depositor's
     knowledge, threatened against the Depositor that, if determined adversely
     to the Depositor, would prohibit the Depositor from entering into this
     Agreement or that, in the Depositor's good faith and reasonable judgment,
     is likely to materially and adversely affect either the ability of the
     Depositor to perform its obligations under this Agreement or the financial
     condition of the Depositor.

          (viii) Immediately prior to the transfer of the Mortgage Loans to the
     Trust Fund pursuant to this Agreement, (A) the Depositor had good and
     marketable title to, and was the sole owner and holder of, each Mortgage

     and transfer the Mortgage Loans and all servicing rights pertaining
     thereto.

          (ix) The Depositor is transferring the Mortgage Loans to the Trust
     Fund free and clear of any liens, pledges, charges and security interests.

     (b) The representations and warranties of the Depositor set forth in
Section 2.04(a) shall survive the execution and delivery of this Agreement and
shall inure to the benefit of the Persons for whose benefit they were made for
so long as the Trust Fund remains in existence. Upon discovery by any party
hereto of any breach of any of the foregoing representations and warranties, the
party discovering such breach shall give prompt written notice thereof to the
other parties.

                 ADMINISTRATION AND SERVICING OF THE TRUST FUND

     SECTION 3.01   Administration of the Mortgage Loans.

     (a) Each of the Master Servicer and the Special Servicer shall service and
administer the Mortgage Loans and the Companion Loans (other than the Fairfield
Common Pari Passu Companion Loan, except as set forth below) that each is
obligated to service and administer pursuant to this Agreement on behalf of the
Trustee, for the benefit of the Certificateholders (and in the case of the
Companion Loans, the Companion Holders, the Certificateholders and the Trust
Fund, as a collective whole, taking into account that the Companion Loans are
subordinate to the related AB Mortgage Loans to the extent set forth in the
related Intercreditor Agreement) in accordance with any and all applicable laws,
the terms of this Agreement, the terms of the respective Mortgage Loans and, in
the case of the Companion Loans, the related Intercreditor Agreement, and, to
the extent consistent with the foregoing, in accordance with the Servicing
Standard. With respect to any Loan Pair, in the event of a conflict between this
Agreement and the related Intercreditor Agreement, the Intercreditor Agreement
will control; provided, in no event shall the Master Servicer or Special
Servicer take any action or omit to take any action in accordance with the terms
of any Intercreditor Agreement that would cause the Master Servicer or the
Special Servicer, as the case may be, to violate the Servicing Standard. Without
limiting the foregoing, and subject to Section 3.21, (i) the Master Servicer
shall service and administer all Mortgage Loans that are not Specially Serviced
Mortgage Loans, and (ii) the Special Servicer shall service and administer each
Specially Serviced Mortgage Loan and REO Property and shall render such services
with respect to all

                                       99
<PAGE>

Mortgage Loans and REO Properties as are specifically provided for herein;
provided, that the Master Servicer shall continue to receive payments, and
prepare, or cause to be prepared, all reports required hereunder with respect to
the Specially Serviced Mortgage Loans, except for the reports specified herein
as prepared by the Special Servicer, as if no Servicing Transfer Event had
occurred and with respect to the REO Properties (and the related REO Loans) as
if no REO Acquisition had occurred, and to render such incidental services with
respect to such Specially Serviced Mortgage Loans and REO Properties as are
specifically provided for herein; provided, further, however, that the Master
Servicer shall not be liable for its failure to comply with such duties insofar
as such failure results from a failure by the Special Servicer to provide
sufficient information to the Master Servicer to comply with such duties or
failure by the Special Servicer to otherwise comply with its obligations
hereunder. All references herein to the respective duties of the Master Servicer
and the Special Servicer, and to the areas in which they may exercise
discretion, shall be subject to Section 3.21.

     The parties hereto acknowledge that, pursuant to the Fairfield Commons
Intercreditor Agreement: (i) until the Fairfield Commons Pari Passu Companion
Loan is included in the Series 2003-C5 Securitization, the Fairfield Commons
Total Loan is to be serviced by the Master Servicer and the Special Servicer
under this Agreement, as generally contemplated in this Agreement; and (ii) as
soon as, and for so long as, the Fairfield Commons Pari Passu Companion Loan is
included in the Series 2003-C5 Securitization, the Fairfield Commons Total Loan
is to be serviced and administered by the Series 2003-C5 Master Servicer and the
Series 2003-C5 Special Servicer in accordance with the Series 2003-C5 Pooling
and Servicing Agreement (provided that the Master Servicer shall be responsible
for performing such services with respect to the Fairfield Commons Total Loan as
are set forth in this Agreement); and (iii) if, after being included in the
Series 2003-C5 Securitization, the Fairfield Commons Pari Passu Companion Loan
is removed from the Series 2003-C5 Securitization, by sale, repurchase, or
otherwise, the Fairfield Commons Total Loan will again be serviced and
administered by the Master Servicer and Special Servicer in accordance with this
Agreement.

     For so long as the Fairfield Commons Pooled Mortgage Loan or any related
REO Loan are part of the Mortgage Pool and are being serviced and administered
under the Series 2003-C5 Pooling and Servicing Agreement, the Master Servicer
shall use reasonable efforts to monitor the performance and, to the extent that
it has standing to do so, enforce the obligations of the Series 2003-C5 Master
Servicer and the Series 2003-C5 Special Servicer, respectively, under such
Series 2003-C5 Pooling and Servicing Agreement. Such enforcement, including the
legal prosecution of claims and the pursuit of other appropriate remedies, shall
be in such form and carried out to such an extent and at such time as the Master
Servicer, in its reasonable judgment, would require were it the owner of the
Fairfield Commons Total Loan. The reasonable costs and expenses incurred by the
Master Servicer in connection with such enforcement shall be paid by, and
reimbursable as, Servicing Advances.

     (b) Subject to Section 3.01(a) and Section 6.11, the Master Servicer and
the Special Servicer each shall have full power and authority, acting alone, to
do or cause to be done any and all things in connection with such servicing and
administration which it may deem necessary or desirable. Without limiting the
generality of the foregoing, each of the Master Servicer and the Special
Servicer, in its own name, with respect to each of the Mortgage Loans and
Companion Loans it is obligated to service hereunder, is hereby authorized and
empowered

                                      100
<PAGE>

by the Trustee and, pursuant to the Intercreditor Agreements, the Companion
Holders, to execute and deliver, on behalf of the Certificateholders, the
Trustee, the Companion Holders or any of them, (i) any and all financing
statements, continuation statements and other documents or instruments necessary
to maintain the lien created by any Mortgage or other security document in the
related Mortgage File on the related Mortgaged Property and related collateral;
(ii) in accordance with the Servicing Standard and subject to Section 3.20 and
Section 6.11, any and all modifications, waivers, amendments or consents to or
with respect to any documents contained in the related Mortgage File; (iii) any
and all instruments of satisfaction or cancellation, or of partial or full
release, discharge, or assignment, and all other comparable instruments; and
(iv) pledge agreements and other defeasance documents in connection with a
defeasance contemplated pursuant to Section 3.20(j). Subject to Section 3.10,
the Trustee shall, at the written request of the Master Servicer or the Special
Servicer, promptly execute any limited powers of attorney and other documents
furnished by the Master Servicer or the Special Servicer that are necessary or
appropriate to enable them to carry out their servicing and administrative
duties hereunder; provided, however, that the Trustee shall not be held liable
for any misuse of any such power of attorney by the Master Servicer or the
Special Servicer. Notwithstanding anything contained herein to the contrary,
neither the Master Servicer nor the Special Servicer shall without the Trustee's
written consent: (i) initiate any action, suit or proceeding solely under the
Trustee's name without indicating the Master Servicer's or Special Servicer's as
applicable, representative capacity or (ii) take any action with the intent to
cause, or which actually does cause, the Trustee to be registered to do business
in any state.

     (c) The relationship of each of the Master Servicer and the Special
Servicer to the Trustee under this Agreement is intended by the parties to be
that of an independent contractor and not that of a joint venture, partner or
agent. Unless the same Person acts as both Master Servicer and Special Servicer,
the Master Servicer shall not be responsible for the actions of or failure to
act by the Special Servicer and the Special Servicer shall not be responsible
for the actions of or the failure to act by the Master Servicer.

     (d) Notwithstanding anything herein to the contrary, in no event shall the
Master Servicer, the Trustee or the Fiscal Agent make a Servicing Advance with
respect to any Companion Loan to the extent the related Pooled Mortgage Loan has
been paid in full or is no longer included in the Trust Fund.

     (e) Servicing and administration of each Companion Loan shall continue
hereunder for so long as the corresponding Pooled Mortgage Loan or any related
REO Property is part of the Trust Fund or for such longer period as any amounts
remain outstanding that are payable by the related Companion Holder to or for
the benefit of the Trust or any party hereto in accordance with the related
Intercreditor Agreement.

     (f) Neither the Master Servicer nor the Special Servicer shall have any
liability for the failure of any Mortgage Loan Seller to perform its obligations
under the related Mortgage Loan Purchase Agreement.

                                      101

     SECTION 3.02   Collection of Mortgage Loan Payments.

     (a) Each of the Master Servicer or the Special Servicer shall undertake
reasonable efforts consistent with the Servicing Standard to collect all
payments required under the terms and provisions of the Mortgage Loans it is
obligated to service hereunder and shall, to the extent such procedures shall be
consistent with this Agreement, follow such collection procedures in accordance
with the Servicing Standard; provided, that with respect to the Mortgage Loans
that have Anticipated Repayment Dates, so long as the related Mortgagor is in
compliance with each provision of the related Mortgage Loan Documents, the
Master Servicer and Special Servicer (including the Special Servicer in its
capacity as a Certificateholder), shall not take any enforcement action with
respect to the failure of the related Mortgagor to make any payment of
Additional Interest or principal in excess of the principal component of the
constant Periodic Payment, other than requests for collection, until the
maturity date of the related Mortgage Loan; provided, that the Master Servicer
or Special Servicer, as the case may be, may take action to enforce the Trust
Fund's right to apply excess cash flow to principal in accordance with the terms
of the Mortgage Loan Documents. The Master Servicer may, in its discretion, with
respect to Mortgage Loans that have Anticipated Repayment Dates, waive any or
all of the Additional Interest accrued on any such Mortgage Loan if the
Mortgagor is ready and willing to pay all other amounts due under such Mortgage
Loan in full, including the Stated Principal Balance, provided that it acts in
accordance with the Servicing Standard and it has received the consent of the
Special Servicer (which consent will be deemed granted if not denied in writing
within 10 Business Days after the Special Servicer's receipt of the Master
Servicer's request for such consent), and neither the Master Servicer nor the
Special Servicer will have any liability to the Trust Fund, the
Certificateholders or any other person for any determination that is made in
accordance with the Servicing Standard. The Master Servicer, with regard to a
Mortgage Loan that is not a Specially Serviced Mortgage Loan, may waive any
Penalty Interest or late payment charge in connection with any payment on such
Mortgage Loan three times during any period of 24 consecutive months. No such
additional waivers shall be permitted without the consent of the Majority
Subordinate Certificateholder.

     (b) All amounts collected in respect of any Mortgage Loan or a Companion
Loan in the form of payments from Mortgagors, Liquidation Proceeds (insofar as
such Liquidation Proceeds are of the nature described in clauses (i) through
(iii) of the definition thereof) or Insurance Proceeds shall be applied to
either amounts due and owing under the related Mortgage Note and Mortgage
(including, without limitation, for principal and accrued and unpaid interest)
in accordance with the express provisions of the related Mortgage Note and
Mortgage (and, with respect to each Loan Pair, the related Intercreditor
Agreement and the documents evidencing and securing the Companion Loan) or, if
required pursuant to the express provisions of the related Mortgage, or as
determined by the Master Servicer or Special Servicer in accordance with the
Servicing Standard, to the repair or restoration of the related Mortgaged
Property, and, in the absence of such express provisions, shall be applied
(after reimbursement first to the Trustee and the Fiscal Agent and second to the
Master Servicer or Special Servicer, as applicable, for any unpaid Master
Servicing Fee, Special Servicing Fee, Principal Recovery Fee, liquidation
expenses and related Additional Trust Fund Expenses) for purposes of this
Agreement: first, in connection with Liquidation Proceeds or Insurance Proceeds
as a recovery of Nonrecoverable Advances and Workout-Delayed Reimbursement
Amounts that were paid from principal collections on the Mortgage Loan and
resulted in principal distributed to the

                                      102
<PAGE>

Certificateholders being reduced; second, as a recovery of any related and
unreimbursed Advances plus unreimbursed interest accrued thereon; third, as a
recovery of Unliquidated Advances; fourth, as a recovery of accrued and unpaid
interest at the related Mortgage Rate on such Mortgage Loan, to the extent such
amounts have not been previously advanced, and exclusive of any portion thereof
that constitutes Additional Interest; fifth, as a recovery of principal of such
Mortgage Loan then due and owing, to the extent such amounts have not been
previously advanced, including, without limitation, by reason of acceleration of
the Mortgage Loan following a default thereunder; sixth, Penalty Interest and
late fees; seventh, in accordance with the normal servicing practices of the
Master Servicer, as a recovery of any other amounts then due and owing under
such Mortgage Loan (other than Additional Interest), including, without
limitation, Prepayment Premiums and Yield Maintenance Charges; eighth, as a
recovery of any remaining principal of such Mortgage Loan to the extent of its
entire remaining unpaid principal balance; and ninth, with respect to any ARD
Loan after its Anticipated Repayment Date, as a recovery of any unpaid
Additional Interest. All amounts collected on any Mortgage Loan in the form of
Liquidation Proceeds of the nature described in clauses (iv) through (vi) of the
definition thereof shall be deemed to be applied: first, as a recovery of any
related and unreimbursed Advances plus interest accrued thereon; second, as a
recovery of accrued and unpaid interest at the related Mortgage Rate on such
Mortgage Loan to but not including the Due Date in the Collection Period of
receipt, to the extent such amounts have not been previously advanced, and
exclusive of any portion thereof that constitutes Additional Interest; third, as
a recovery of principal, to the extent such amounts have not been previously
advanced, of such Mortgage Loan to the extent of its entire unpaid principal
balance; and fourth, with respect to any ARD Loan after its Anticipated
Repayment Date, as a recovery of any unpaid Additional Interest. Amounts
collected on any REO Loan shall be deemed to be applied in accordance with the
definition thereof. The provisions of this paragraph with respect to the
application of amounts collected on any Mortgage Loan shall not alter in any way
the right of the Master Servicer, the Special Servicer or any other Person to
receive payments from the Certificate Account as set forth in clauses (ii)
through (xiv) of Section 3.05(a) from amounts so applied.

     (c) Reserved.

     (d) To the extent consistent with the terms of the Mortgage Loans (and,
with respect to each Loan Pair, the related Companion Loan and Intercreditor
Agreement) and applicable law, the Master Servicer shall apply all Insurance
Proceeds and condemnation proceeds it receives on a day other than the Due Date
to amounts due and owing under the related Mortgage Loan as if such Insurance
Proceeds and condemnation proceeds were received on the Due Date immediately
succeeding the month in which such Insurance Proceeds and condemnation proceeds
were received.

     (e) The Master Servicer shall, on the day of receipt thereof, deposit into
the Companion Loan Custodial Account with respect to the Fairfield Commons Total
Loan all amounts received by it from the Series 2003-C5 Master Servicer or any
other party under the Series 2003-C5 Pooling and Servicing Agreement with
respect to the Fairfield Commons Total Loan or the related Mortgaged Property or
REO Property. In the event the Master Servicer fails to so receive any amounts
due to the holder of the Fairfield Commons Total Loan during any calendar month
under the Fairfield Commons Intercreditor Agreement by 11:00 a.m. (New York City
time) on the P&I Advance Date in such calendar month, the Master Servicer shall
(i) notify

                                      103
<PAGE>

the Series 2003-C5 Master Servicer or other applicable party responsible for
making such remittances that such amounts due with respect to the Fairfield
Commons Total Loan have not been received (specifying the amount of such
deficiency) and (ii) if and to the extent that the amount in question is a
Monthly Payment or Assumed Monthly Payment with respect to the Fairfield Commons
Pooled Mortgage Loan or any related REO Loan, make a P&I Advance (to the extent
it has not been determined that such P&I Advance would be a Nonrecoverable
Advance) with respect to such amounts as required by the terms of this Agreement
in accordance with Section 4.03. Further, in accordance with Section 4.03, in
the event the Master Servicer fails to make such P&I Advance with respect to the
Fairfield Commons Pooled Mortgage Loan or a related REO Loan, then the Trustee
or the Fiscal Agent shall make such P&I Advance.

     (f) In the event that the Master Servicer or Special Servicer receives
Additional Interest in any Collection Period, or receives notice from the
related Mortgagor that the Master Servicer or Special Servicer will be receiving
Additional Interest in any Collection Period, the Master Servicer or Special
Servicer, as applicable, will promptly notify the Trustee. Subject to the
provisions of Section 3.02(a) hereof, none of the Master Servicer, the Trustee,
the Fiscal Agent or the Special Servicer shall be responsible for any such
Additional Interest not collected after notice from the related Mortgagor.

     (g) With respect to any Mortgage Loan in connection with which the
Mortgagor was required to escrow funds or to post a letter of credit related to
obtaining certain performance objectives described in the applicable Mortgage
Loan Documents, the Master Servicer (with the consent of the Special Servicer)
to the extent the Mortgage Loan Documents provide for any discretion, with
respect to non-Specially Serviced Mortgage Loans, or the Special Servicer, with
respect to Specially Serviced Mortgage Loans shall, to the extent consistent
with the Servicing Standard, hold such escrows, letters of credit and proceeds
thereof as additional collateral and not apply such items to reduce the
principal balance of such Mortgage Loan unless otherwise required to do so
pursuant to the applicable Mortgage Loan Documents, applicable law or the
Servicing Standard.

     SECTION 3.03   Collection of Taxes, Assessments and Similar Items;
Servicing Accounts; Reserve Accounts.

     (a) The Master Servicer shall, as to all Mortgage Loans establish and
maintain one or more accounts (the "Servicing Accounts"), into which all Escrow
Payments shall be deposited and retained, and shall administer such accounts in
accordance with the terms of the Mortgage Loan Documents. Each Servicing Account
shall be an Eligible Account unless not permitted by the terms of the Mortgage
Loan Documents. Withdrawals of amounts so collected from a Servicing Account may
be made (to the extent amounts have been escrowed for such purpose) only to: (i)
effect payment of items for which Escrow Payments were collected and comparable
items; (ii) reimburse the Master Servicer, the Trustee or the Fiscal Agent for
any unreimbursed Servicing Advances; (iii) refund to Mortgagors any sums as may
be determined to be overages; (iv) pay interest, if required and as described
below, to Mortgagors on balances in the Servicing Account; (v) pay itself
interest and investment income on balances in the Servicing Account as described
in Section 3.06(b), if and to the extent not required by law or the terms of the
applicable Mortgage Loan to be paid to the Mortgagor; (vi) withdraw amounts
deposited in error; (vii) clear and terminate the Servicing Account at the
termination of this Agreement in

                                      104
<PAGE>

accordance with Section 9.01; or (viii) only as, when and to the extent required
under the terms of the related Intercreditor Agreement with respect to each Loan
Pair, and for all other Mortgage Loans, to the extent permitted under the
Mortgage Loan Documents, to effect payment of accrued and unpaid late charges,
default interest and other reasonable fees. To the extent permitted by law or
the applicable Mortgage Loan, funds in the Servicing Accounts may be invested
only in Permitted Investments in accordance with the provisions of Section 3.06
and in accordance with the terms of the related Mortgage Loan Documents. The
Master Servicer shall pay or cause to be paid to the Mortgagors interest, if
any, earned on the investment of funds in Servicing Accounts maintained thereby,
if required by law or the terms of the related Mortgage Loan. If the Master
Servicer shall deposit in a Servicing Account any amount not required to be
deposited therein, it may at any time withdraw such amount from such Servicing
Account, any provision herein to the contrary notwithstanding. The Servicing
Accounts shall not be considered part of the segregated pool of assets
constituting 77 West Wacker Drive Loan REMIC, REMIC I, REMIC II or the Grantor
Trust.

     (b) The Master Servicer (or the Special Servicer for Specially Serviced
Mortgage Loans and REO Loans) shall (i) maintain accurate records with respect
to the related Mortgaged Property reflecting the status of real estate taxes,
assessments and other similar items that are or may become a lien thereon and
the status of insurance premiums and any ground rents payable in respect thereof
and (ii) use reasonable efforts to obtain, from time to time, all bills for the
payment of such items (including renewal premiums) and shall effect payment
thereof prior to the applicable penalty or termination date and, in any event,
prior to the institution of foreclosure or similar proceedings with respect to
the related Mortgaged Property for nonpayment of such items. For purposes of
effecting any such payment for which it is responsible, the Master Servicer
shall apply Escrow Payments (at the direction of the Special Servicer for
Specially Serviced Mortgage Loans and REO Loans) as allowed under the terms of
the related Mortgage Loan or, if such Mortgage Loan does not require the related
Mortgagor to escrow for the payment of real estate taxes, assessments, insurance
premiums, ground rents (if applicable) and similar items, the Master Servicer
shall, as to all Mortgage Loans, use reasonable efforts consistent with the
Servicing Standard to enforce the requirement of the related Mortgage that the
Mortgagor make payments in respect of such items at the time they first become
due, and, in any event, prior to the institution of foreclosure or similar
proceedings with respect to the related Mortgaged Property for nonpayment of
such items.

     (c) The Master Servicer shall, as to all Mortgage Loans (other than the
Fairfield Commons Total Loan and the related Mortgaged Property, so long as the
Fairfield Commons Pari Passu Companion Loan is included in the Series 2003-C5
Securitization), make a Servicing Advance with respect to the related Mortgaged
Property in an amount equal to all such funds as are necessary for the purpose
of effecting the payment of the costs and expenses described in the definition
of "Servicing Advances", provided that the Master Servicer shall not make any
Servicing Advance prior to the penalty date or cancellation date, as applicable,
if the Master Servicer reasonably anticipates in accordance with the Servicing
Standard that the Mortgagor will pay such amount on or before the penalty date
or cancellation date, and provided, further, that the Master Servicer shall not
be obligated to make any Servicing Advance that would, if made, constitute a
Nonrecoverable Servicing Advance. All such Servicing Advances shall be
reimbursable in the first instance from related collections from the Mortgagors,
and in the case of REO Properties, from the operating revenues related thereto,
and further as provided in Section

                                      105
<PAGE>

3.05(a). No costs incurred by the Master Servicer in effecting the payment of
real estate taxes, assessments and, if applicable, ground rents on or in respect
of such Mortgaged Properties shall, for purposes of this Agreement, including,
without limitation, the Trustee's calculation of monthly distributions to
Certificateholders, be added to the unpaid Stated Principal Balances of the
related Mortgage Loans, notwithstanding that the terms of such Mortgage Loans so
permit. The foregoing shall in no way limit the Master Servicer's ability to
charge and collect from the Mortgagor such costs together with interest thereon.

     The Special Servicer shall give the Master Servicer, the Trustee and the
Fiscal Agent not less than five Business Days' notice with respect to Servicing
Advances to be made on any Specially Serviced Mortgage Loan or REO Property,
before the date on which the Master Servicer is required to make any Servicing
Advance with respect to a given Mortgage Loan or REO Property; provided,
however, that the Special Servicer may make any Servicing Advance on a Specially
Serviced Mortgage Loan or REO Property only as may be required on an urgent or
emergency basis. In addition, the Special Servicer shall provide the Master
Servicer, the Trustee and the Fiscal Agent with such information in its
possession as the Master Servicer, the Trustee or the Fiscal Agent, as
applicable, may reasonably request to enable the Master Servicer, the Trustee or
the Fiscal Agent, as applicable, to determine whether a requested Servicing
Advance would constitute a Nonrecoverable Servicing Advance. The Special
Servicer shall not be entitled to deliver such a notice (other than for
emergency Servicing Advances) more frequently than once per calendar month
(although such notice may relate to more than one Servicing Advance). The Master
Servicer will have the obligation to make any such Servicing Advance (other than
a Nonrecoverable Servicing Advance) that it is so requested by a Special
Servicer to make, within five Business Days after the Master Servicer's receipt
of such request. If the request is timely and properly made, the Special
Servicer shall be relieved of any obligations with respect to a Servicing
Advance that it so requests the Master Servicer to make with respect to any
Mortgage Loan or REO Property (regardless of whether or not the Master Servicer
shall make such Servicing Advance). The Master Servicer shall be entitled to
reimbursement for any Servicing Advance made by it at the direction of a Special
Servicer, together with interest accrued thereon, at the same time, in the same
manner and to the same extent as the Master Servicer is entitled with respect to
any other Servicing Advances made thereby. Any request by the Special Servicer
that the Master Servicer make a Servicing Advance shall be deemed to be a
determination by the Special Servicer that such requested Servicing Advance is
not a Nonrecoverable Servicing Advance, and the Master Servicer shall be
entitled to conclusively rely on such determination. On the fourth Business Day
before each Distribution Date, the Special Servicer shall report to the Master
Servicer the Special Servicer's determination as to whether any Servicing
Advance previously made with respect to a Specially Serviced Mortgage Loan or
REO Loan is a Nonrecoverable Servicing Advance. The Master Servicer shall be
entitled to conclusively rely on such a determination.

     No later than 1:00 p.m. New York City time on the first Determination Date
that follows the date on which it makes any Servicing Advance, the Special
Servicer shall provide the Master Servicer an Officer's Certificate (via
facsimile) setting forth the details of the Servicing Advance, upon which the
Master Servicer may conclusively rely in reimbursing the Special Servicer. The
Master Servicer shall be obligated, out of its own funds, to reimburse the
Special Servicer for any unreimbursed Servicing Advances (other than
Nonrecoverable Servicing Advances) made by the Special Servicer together with
interest thereon at the Reimbursement

                                      106
<PAGE>

Rate from the date made to, but not including, the date of reimbursement. Any
such reimbursement, together with any accompanying payment of interest, shall be
made by the Master Servicer, by wire transfer of immediately available funds to
an account designated by the Special Servicer, no later than the first P&I
Advance Date that is at least three (3) Business Days after the date on which
the Master Servicer receives the corresponding Officer's Certificate
contemplated by the prior sentence; provided, that any such Officer's
Certificate received after 1:00 p.m., New York City time, on any particular date
shall, for purposes of any such reimbursement, be deemed received on the next
succeeding Business Day. Upon its reimbursement to the Special Servicer of any
Servicing Advance and payment to the Special Servicer of interest thereon, the
Master Servicer shall for all purposes of this Agreement be deemed to have made
such Servicing Advance at the same time as the Special Servicer actually made
such Servicing Advance, and accordingly, the Master Servicer shall be entitled
to reimbursement for such Servicing Advance, together with interest accrued
thereon, at the same time, in the same manner and to the same extent as the
Master Servicer would otherwise have been entitled if it had actually made such
Servicing Advance at the time the Special Servicer did.

     Notwithstanding the foregoing provisions of this Section 3.03(c), the
Master Servicer shall not be required to reimburse the Special Servicer for, or
to make at the direction of the Special Servicer, any Servicing Advance if the
Master Servicer determines in its reasonable judgment that such Servicing
Advance, although not characterized by the Special Servicer as a Nonrecoverable
Servicing Advance, is in fact a Nonrecoverable Servicing Advance. The Master
Servicer shall notify the Special Servicer in writing of such determination and,
if applicable, such Nonrecoverable Servicing Advance shall be reimbursed to the
Special Servicer pursuant to Section 3.05(a).

     If the Master Servicer is required under any provision of this Agreement
(including, but not limited to, this Section 3.03(c)) to make a Servicing
Advance, but does not do so within 15 days after such Advance is required to be
made, the Trustee shall, if a Responsible Officer of the Trustee has actual
knowledge of such failure on the part of the Master Servicer, give written
notice of such failure to the Master Servicer. If such Servicing Advance is not
made by the Master Servicer within three Business Days after such notice then
(subject to a determination that such Servicing Advance would not be a
Nonrecoverable Servicing Advance) the Trustee shall make such Servicing Advance.
If the Trustee does not make such Servicing Advance within such period, the
Fiscal Agent shall make such Servicing Advance within such period. Any failure
by the Master Servicer to make a Servicing Advance hereunder shall constitute an
Event of Default by the Master Servicer subject to and as provided in Section
7.01.

     (d) In connection with its recovery of any Servicing Advance from the
Certificate Account pursuant to Section 3.05(a), each of the Master Servicer,
the Trustee and the Fiscal Agent shall be entitled to receive, out of amounts
then on deposit in the Certificate Account as provided in Section 3.05(a), any
unpaid interest at the Reimbursement Rate (or, with respect to each Loan Pair,
the rate provided in the related Intercreditor Agreement) in effect from time to
time, accrued on the amount of such Servicing Advance (to the extent made with
its own funds) from the date made to but not including the date of reimbursement
such interest to be payable (it being acknowledged that interest shall not
accrue on Unliquidated Advances related to prior Servicing Advances), first,
subject to the terms of the related Intercreditor Agreement with respect to each
Loan Pair, out of late payment charges and Penalty Interest received on the

                                      107
<PAGE>

related Mortgage Loans, Companion Loans and REO Properties during the Collection
Period in which such reimbursement is made, and to the extent that such late
payment charges and Penalty Interest are insufficient, but only after or at the
same time the related Advance has been or is reimbursed pursuant to this
Agreement, then from general collections on the Mortgage Loans and Companion
Loans then on deposit in the Certificate Account. The Master Servicer shall
reimburse itself, the Trustee or the Fiscal Agent, as applicable, for any
outstanding Servicing Advance made thereby as soon as practicable after funds
available for such purpose have been received by the Master Servicer, and in no
event shall interest accrue in accordance with this Section 3.03(d) on any
Servicing Advance as to which the corresponding Escrow Payment or other similar
payment by the Mortgagor was received by the Master Servicer on or prior to the
date the related Servicing Advance was made. Notwithstanding anything herein to
the contrary, in no event shall the Master Servicer, the Trustee or the Fiscal
Agent be entitled to reimbursement from funds on deposit in the Certificate
Account for any Servicing Advance made solely with respect to any Companion Loan
to the extent that the related AB Mortgage Loan has been paid in full.

     (e) The determination by the Master Servicer or the Special Servicer that
either has made a Nonrecoverable Servicing Advance or that any proposed
Servicing Advance, if made, would constitute a Nonrecoverable Servicing Advance,
shall be made in accordance with the Servicing Standard and shall be evidenced
by an Officers' Certificate delivered promptly to the Trustee, the Fiscal Agent
and the Depositor, setting forth the basis for such determination, together with
a copy of any Appraisal (the cost of which may be paid out of the Certificate
Account pursuant to Section 3.05(a)) of the related Mortgaged Property or REO
Property, as the case may be; which Appraisal shall be obtained pursuant to
Section 3.09(a) by the Master Servicer, or by or on behalf of the Special
Servicer if the Mortgage Loan is a Defaulted Mortgage Loan (or, if no such
Appraisal has been performed, a copy of an Appraisal of the related Mortgaged
Property or REO Property, performed within the twelve months preceding such
determination and the party delivering such appraisal has no actual knowledge of
a material adverse change in the condition of the related Mortgaged Property
that would draw into question the applicability of such Appraisal) and further
accompanied by related Mortgagor operating statements and financial statements,
budgets and rent rolls of the related Mortgaged Property and any engineers'
reports, environmental surveys or similar reports that the Master Servicer or
the Special Servicer may have obtained and that support such determination. The
Trustee and the Fiscal Agent shall be entitled to rely, conclusively, on any
determination by the Master Servicer or the Special Servicer that a Servicing
Advance, if made, would be a Nonrecoverable Advance; provided, however, that if
the Master Servicer has failed to make a Servicing Advance for reasons other
than a determination by the Master Servicer that such Servicing Advance would be
a Nonrecoverable Advance, the Trustee or the Fiscal Agent shall make such
Servicing Advance within the time periods required by Section 3.03(c) unless the
Trustee or the Fiscal Agent in good faith, makes a determination that such
Servicing Advance would be a Nonrecoverable Advance. The applicable Person shall
consider Unliquidated Advances in respect of prior Servicing Advances as
outstanding Advances for purposes of recoverability determinations as if such
Unliquidated Advance were a Servicing Advance.

     (f) The Master Servicer shall, as to all Mortgage Loans (other than the
Fairfield Commons Total Loan so long as the Fairfield Commons Pari Passu
Companion Loan is included in the Series 2003-C5 Securitization), establish and
maintain, as applicable, one or more

                                      108
<PAGE>

accounts (the "Reserve Accounts"), into which all Reserve Funds, if any, shall
be deposited and retained. Withdrawals of amounts so deposited may be made (i)
to pay for, or to reimburse the related Mortgagor in connection with, the
related environmental remediation, repairs and/or capital improvements at the
related Mortgaged Property if the repairs and/or capital improvements have been
completed, and such withdrawals are made in accordance with the Servicing
Standard and the terms of the related Mortgage Note, Mortgage and any agreement
with the related Mortgagor governing such Reserve Funds and any other items for
which such Reserve Funds were intended pursuant to the loan documents and (ii)
to pay the Master Servicer interest and investment income earned on amounts in
the Reserve Accounts if permitted under the related Mortgage Loan Documents. To
the extent permitted in the applicable Mortgage, funds in the Reserve Accounts
to the extent invested may be only invested in Permitted Investments in
accordance with the provisions of Section 3.06. All Reserve Accounts shall be
Eligible Accounts. The Reserve Accounts shall not be considered part of the
segregated pool of assets comprising 77 West Wacker Drive Loan REMIC, REMIC I,
REMIC II or the Grantor Trust. Consistent with the Servicing Standard, the
Master Servicer may waive or extend the date set forth in any agreement
governing such Reserve Funds by which the required repairs and/or capital
improvements at the related Mortgaged Property must be completed.

     (g) Notwithstanding anything to the contrary in this Agreement, but subject
to the limitations on reimbursements in Section 4.03, the Master Servicer may
(and, at the direction of the Special Servicer if a Specially Serviced Mortgage
Loan or an REO Property is involved, shall) pay directly out of the Certificate
Account any servicing expense that, if paid by the Master Servicer or the
Special Servicer, would constitute a Nonrecoverable Servicing Advance for the
subject Mortgage Loan or REO Property; provided, that the Master Servicer (or
the Special Servicer, if a Specially Serviced Mortgage Loan or an REO Property
is involved) has determined in accordance with the Servicing Standard that
making such payment is in the best interests of the Certificateholders (as a
collective whole), as evidenced by an Officer's Certificate delivered promptly
to the Depositor, the Trustee and the Controlling Class Representative, setting
forth the basis for such determination and accompanied by any information that
such Person may have obtained that supports such determination. The Master
Servicer and the Special Servicer shall deliver a copy of any such Officer's
Certificate (and accompanying information) promptly to the other such Person.

     (h) To the extent an operations and maintenance plan is required to be
established and executed pursuant to the terms of a Mortgage Loan, the Master
Servicer shall request from the Mortgagor written confirmation thereof within a
reasonable time after the later of the Closing Date and the date as of which
such plan is required to be established or completed. To the extent any repairs,
capital improvements, actions or remediations are required to have been taken or
completed pursuant to the terms of the Mortgage Loan, the Master Servicer shall
request from the Mortgagor written confirmation of such actions and remediations
within a reasonable time after the later of the Closing Date and the date as of
which such action or remediations are required to be or to have been taken or
completed. To the extent a Mortgagor shall fail to promptly respond to any
inquiry described in this Section 3.03(h), the Master Servicer shall report any
such failure to the Special Servicer within a reasonable time after April 15,
2004.

     the definition thereof that are required to be deposited in the
     Distribution Account or the 77 West Wacker Drive Distribution Account
     pursuant to Section 9.01) received in respect of any Mortgage Loan and
     together with any amounts representing recoveries of Workout-Delayed
     Reimbursement Amounts or Nonrecoverable Advances in respect of the related
     Mortgage Loans and all condemnation proceeds or any award received in

Certificate Account, any provision herein to the contrary notwithstanding. The
Master Servicer shall promptly deliver to the Special Servicer as additional

but in no event later than one Business Day after receipt of available funds,
remit such amounts (net of any reimbursable expenses incurred by the Special

Certificate Account in accordance with the second preceding paragraph, unless
the Special Servicer determines, consistent with the Servicing Standard, that a
particular item should not be deposited because of a restrictive endorsement.
Any such amounts received by the Special Servicer with respect to an REO
Property shall be deposited by the Special Servicer into the REO Account and
remitted to the Master Servicer for deposit into the Certificate Account

amounts contemplated by the second paragraph of Section 9.01 (including that
portion of such amounts allocable to the 77 West Wacker Drive Pooled Portion).

     In addition, the Master Servicer shall, as and when required hereunder,

equal to the Interest Reserve Amount in respect of such Interest Reserve Loan
for such Distribution Date (such withdrawal from the Distribution Account to be
made out of general collections on the Mortgage Pool including any related P&I
Advance that was deposited in the Distribution Account).

     (1) above (provided that, in case of such reimbursement relating to an AB

     collected on the related Companion Loan and then from the related Mortgage
     Loan in accordance with the terms of the related Intercreditor Agreement)
     or to pay itself, with respect to any Mortgage Loan and the Companion

     the Fiscal Agent, the Trustee, the Special Servicer or itself, as the case
     may be, in that order, any interest accrued and payable thereon in

     Master Servicer's rights to payment pursuant to this clause (viii) with
     respect to interest on any Advance being permitted to be satisfied (A)
     subject to the terms of the related Intercreditor Agreement with respect to
     each Loan Pair, out of late payment charges and Penalty Interest collected
     on or in respect of the related Mortgage Loan (and if the Advance was made
     with respect to a Mortgage Loan with a Companion Loan, out of such amounts
     collected on or in respect of the related Companion Loan) and REO Loan,
     during the Collection Period in which such Advance is reimbursed (the use
     of such late payment charges and Penalty Interest to be allocated pursuant
     to Section 3.27), and (B) to the extent that the late payment charges and
     Penalty Interest described in the immediately preceding clause (A) are

     Companion Loan and then from the related Mortgage Loan in accordance with
     the terms of the related Intercreditor Agreement);

     with Section 3.11(b), (A) interest and investment income earned in respect
     of amounts held in the Certificate Account as provided in Section 3.06(b),

     Certificate Account for any Collection Period; (B) any Prepayment Interest
     Excesses (after deduction of the amounts required to be deposited by the
     Master Servicer in the Certificate Account for the related Distribution

     Servicer or the Special Servicer that protects or is in furtherance of the
     rights and interests of Certificateholders, and (D) the cost of recording
     this Agreement in accordance with Section 11.02(a);

          (xiv) to pay itself, the Special Servicer, any of the Mortgage Loan
     Sellers, the Majority Subordinate Certificateholder, any Companion Holder
     or any other Person, as the case may be, with respect to each Mortgage
     Loan, if any, previously purchased by such Person pursuant to this
     Agreement, all amounts received thereon subsequent to the date of purchase;

          (xv) to remit to the Trustee for deposit into the Additional Interest
     Account the amounts required to be deposited pursuant to Section 3.04(d);

          (xvi) to remit to the Trustee for deposit into the Distribution
     Account the amounts required to be deposited pursuant to Section 3.04(b);

          (xviii) to pay the cost of any Environmental Assessment or any
     remedial, corrective or other action pursuant to Section 3.09(c);

          (xix) to withdraw any amounts deposited in error;

          (xx) to withdraw any other amounts that this Agreement expressly
     provides may be withdrawn from the Certificate Account; and

          (xxi) to clear and terminate the Certificate Account at the
     termination of this Agreement pursuant to Section 9.01.

     The Master Servicer shall keep and maintain separate accounting records, on
a loan-by-loan basis when appropriate, in connection with any withdrawal from
the Certificate

                                      119
<PAGE>

Account pursuant to clauses (ii)-(xviii) above and such records shall be
sufficient to determine the amounts attributable to 77 West Wacker Drive Loan
REMIC and REMIC I. The Master Servicer shall, to the extent permitted by the
terms of the related Intercreditor Agreement, make claims for reimbursement from
the related Companion Holder in connection with related Servicing Advances and
interest thereon and other related expenses so as to minimize the total amount
of withdrawals on the Certificate Account for such items. Notwithstanding
anything in this Section 3.05(a) to the contrary, in no event shall the Master
Servicer withdraw from funds on deposit in the Certificate Account any amount to
be applied to, or to provide reimbursement for, any amounts referenced in this
Section 3.05(a) (other than amounts referenced in clause (xviii)) which relate
to any Companion Loan to the extent the related AB Mortgage Loan has been paid
in full in a prior Collection Period.

     The Master Servicer shall pay to the Special Servicer, the Trustee or the
Fiscal Agent on each P&I Advance Date from the Certificate Account amounts
permitted to be paid to the Special Servicer, the Trustee or the Fiscal Agent
therefrom based on a certificate of a Servicing Officer of the Special Servicer
or of a Responsible Officer of the Trustee or the Fiscal Agent, as the case may
be, received not later than 1:00 p.m. (New York City time) on the immediately
preceding Determination Date and describing the item and amount to which the
Special Servicer, the Trustee or the Fiscal Agent, as the case maybe, is
entitled. The Master Servicer may rely conclusively on any such certificate and
shall have no duty to re-calculate the amounts stated therein. The Special
Servicer shall keep and maintain separate accounting for each Specially Serviced
Mortgage Loan and REO Property, on a loan-by-loan and property-by-property
basis, for the purpose of justifying any request for withdrawal from the
Certificate Account. With respect to each Mortgage Loan for which it makes an
Advance, the Trustee and the Fiscal Agent shall similarly keep and maintain
separate accounting for each Mortgage Loan, on a loan-by-loan and
property-by-property basis, for the purpose of justifying any request for
withdrawal from the Certificate Account for reimbursements of Advances or
interest thereon.

     To the extent a Nonrecoverable Advance or Workout-Delayed Reimbursement
Amount with respect to a Mortgage Loan is required to be reimbursed from the
principal portion of the general collections on the Mortgage Loans pursuant to
clauses (ii), (vi) or (vii) of this Section 3.05(a), such reimbursement shall be
made first, from the principal collection available on the Mortgage Loans
included in the same Loan Group as such Mortgage Loan and if the principal
collections in such Loan Group are not sufficient to make such reimbursement in
full, then from the principal collections available in the other Loan Group
(after giving effect to any reimbursement of Nonrecoverable Advances and
Workout-Delayed Reimbursement Amounts related to such other Loan Group) and if
the principal collections in such other Loan Group are not sufficient to make
such reimbursement in full, then from the principal collections available for
distribution in respect of the 77 West Wacker Drive Non-Pooled Portion (after
giving effect to any reimbursement of Nonrecoverable Advances and
Workout-Delayed Reimbursement Amounts in respect thereof).

     (b) The Trustee may, from time to time, make withdrawals from the
Distribution Account for any of the following purposes (in no particular order
of priority):

                                      120

          (i) to make deemed distributions to itself as holder of the REMIC I

          (ii) to pay itself, the Fiscal Agent or any of their directors,

     contemplated by Section 11.01(a) or 11.01(c) in connection with any
     amendment to this Agreement requested by the Trustee which amendment is in
     furtherance of the rights and interests of Certificateholders;

          (v) to pay any and all federal, state and local taxes imposed on any
     of the REMICs created hereunder or on the assets or transactions of any
     such REMIC, together with all incidental costs and expenses, to the extent
     none of the Trustee, the REMIC Administrator, the Master Servicer or the
     Special Servicer is liable therefor pursuant to Section 10.01(i);

          (vi) to pay the REMIC Administrator any amounts reimbursable to it
     pursuant to Section 10.01(f);

          (vii) to pay to the Master Servicer any amounts deposited by the
     Master Servicer in the Distribution Account not required to be deposited
     therein;

          (viii) to withdraw any Interest Reserve Amount and deposit such
     Interest Reserve Amount into the Interest Reserve Account pursuant to
     Section 3.04(c); and

          (ix) to clear and terminate the Distribution Account at the
     termination of this Agreement pursuant to Section 9.01.

     (c) The Master Servicer may, from time to time, make withdrawals from the
Companion Loan Custodial Account as contemplated by Section 3.04(f) and 6.03(b).

     (d) The Trustee shall on each Distribution Date to occur in March of each
year, withdraw from the Interest Reserve Account and deposit into the
Distribution Account in respect of each Interest Reserve Loan (excluding the 77
West Wacker Drive Non-Pooled Portion, an amount equal to the aggregate of the
Interest Reserve Amounts deposited into the Interest Reserve Account pursuant to
Section 3.04(c) during the immediately preceding Collection Period and, if
applicable, the second preceding Collection Period.

                                      121

     (e) The Trustee shall, on any Distribution Date, make withdrawals from the
Additional Interest Account to the extent required to make the distributions of
Additional Interest required by Section 4.01(b).

     (f) The Trustee may, from time to time, make withdrawals from the 77 West
Wacker Drive Distribution Account for any of the following purposes (in no
particular order of priority):

          (i) to make deemed distributions to itself in respect of the 77 West
     Wacker Drive Mortgage Loan as holder of the 77 West Wacker Drive Loan REMIC
     Regular Interests and to make distributions to Certificateholders on each
     Distribution Date pursuant to Section 4.01(k) and (l) or 9.01, as
     applicable;

          (ii) to pay itself, the Fiscal Agent or any of their directors,
     officers, employees and agents, as the case may be, any amounts in respect
     of the 77 West Wacker Drive Non-Pooled Portion payable or reimbursable to
     any such Person pursuant to Section 8.05 to the extent not paid pursuant to
     Section 4.01(i);

     amendment to this Agreement requested by the Trustee which amendment is in

          (v) to the extent related to the 77 West Wacker Drive Non-Pooled
     Portion, pay any and all federal, state and local taxes imposed on any of
     the REMICs created hereunder or on the assets or transactions of any such
     REMIC, together with all incidental costs and expenses, to the extent none

     Servicer is liable therefor pursuant to Section 10.01(i);

          (vi) to pay the REMIC Administrator any amounts in respect of the 77

     SECTION 3.06   Investment of Funds in the Servicing Accounts, the Reserve
Accounts, the Certificate Account, the Distribution Account, the 77 West Wacker
Drive Distribution Account, the Additional Interest Account, the Companion Loan
Custodial Accounts, the Gain-on-Sale Reserve Account and the REO Account.

     (a) The Master Servicer may direct in writing any depository institution
maintaining a Servicing Account, a Reserve Account, a Companion Loan Custodial
Account or the Certificate Account (each, for purposes of this Section 3.06, an
"Investment Account"), and the Special Servicer may direct in writing any
depository institution maintaining the REO Account (also, for purposes of this
Section 3.06, an "Investment Account"), to invest, or if it is such depository
institution, may itself invest, the funds held therein only in one or more
Permitted Investments bearing interest or sold at a discount, and maturing,
unless payable on demand, no later than the Business Day immediately preceding
the next succeeding date on which such funds are required to be withdrawn from
such account pursuant to this Agreement. Funds held in the Distribution Account,
the 77 West Wacker Drive Distribution Account, the Gain-on-Sale Reserve Account,
the Additional Interest Account and the Interest Reserve Account shall remain
uninvested. In the event that the Master Servicer shall have failed to give
investment directions for any Servicing Account, any Reserve Account, the
Certificate Account, or the Special Servicer shall have failed to give
investment directions for the REO Account by 11:00 A.M. New York time on any
Business Day on which there may be uninvested cash, such funds held in the REO
Account shall be invested in securities described in clause (i) of the
definition of the term "Permitted Investments"; and such funds held in such
other accounts shall be invested in securities described in clause (v) of such
definition. All such Permitted Investments shall be held to maturity, unless
payable on demand. Any investment of funds in an Investment Account shall be
made in the name of the Trustee (in its capacity as such). The Master Servicer
(with respect to Permitted Investments of amounts in the Servicing Accounts, the
Reserve Accounts or the Certificate Account) and the Special Servicer (with
respect to Permitted Investments of amounts in the REO Account), on behalf of
the Trustee, shall (and the Trustee hereby designates the Master Servicer and
the Special Servicer, as applicable, as the person that shall) maintain
continuous possession of any Permitted Investment that is either (i) a
"certificated security", as such term is defined in the UCC, or (ii) other
property in which a secured party may perfect its security interest by
possession under the UCC or any other applicable law. Possession of any such
Permitted Investment by the Master Servicer or the Special Servicer shall
constitute possession by the Trustee, as secured party, for purposes of Section
9-313 of the UCC and any other applicable law. If amounts on deposit in an
Investment Account are at any time invested in a Permitted Investment payable on
demand, the Master Servicer (in the case of the Certificate Account, Servicing
Accounts and Reserve Accounts), or the Special Servicer (in the case of the REO
Account) shall:

          (i) consistent with any notice required to be given thereunder, demand
     that payment thereon be made on the last day such Permitted Investment may
     otherwise mature hereunder in an amount equal to the lesser of (1) all
     amounts then payable thereunder and (2) the amount required to be withdrawn
     on such date; and

          (ii) demand payment of all amounts due thereunder promptly upon
     determination by the Master Servicer or the Special Servicer, as the case
     may be, that

                                      123
<PAGE>

     such Permitted Investment would not constitute a Permitted Investment in
     respect of funds thereafter on deposit in the Investment Account.

     (b) Whether or not the Master Servicer directs the investment of funds in
any of the Servicing Accounts, the Reserve Accounts or the Certificate Account,
interest and investment income realized on funds deposited therein, to the
extent of the related Net Investment Earnings, if any, for each Collection
Period and, in the case of a Reserve Account or a Servicing Account, to the
extent not otherwise payable to the related Mortgagor in accordance with
applicable law or the related Mortgage Loan Documents, shall be for the sole and
exclusive benefit of the Master Servicer and shall be subject to its withdrawal
in accordance with Section 3.03(a), 3.03(f) or 3.05(a), as applicable. Whether
or not the Special Servicer directs the investment of funds in the REO Account,
interest and investment income realized on funds deposited therein, to the
extent of the Net Investment Earnings, if any, for each Collection Period, shall
be for the sole and exclusive benefit of the Special Servicer and shall be
subject to its withdrawal in accordance with Section 3.16(b). If any loss shall
be incurred in respect of any Permitted Investment on deposit in any Investment
Account, the Master Servicer (in the case of the Servicing Accounts, the Reserve
Accounts and the Certificate Account, excluding any accounts containing amounts
invested solely for the benefit of, and at the direction of, the Mortgagor under
the terms of the Mortgage Loan or applicable law) and the Special Servicer (in
the case of the REO Account) shall promptly deposit therein from its own funds,
without right of reimbursement, no later than the end of the Collection Period
during which such loss was incurred, the amount of the Net Investment Loss, if
any, for such Collection Period, provided, that neither the Master Servicer nor
the Special Servicer shall be required to deposit any loss on an investment of
funds in an Investment Account if such loss is incurred solely as a result of
the insolvency of the federal or state chartered depository institution or trust
company that holds such Investment Account, so long as such depository
institution or trust company satisfied the qualifications set forth in the
definition of Eligible Account immediately prior to such insolvency.

     (c) Except as otherwise expressly provided in this Agreement, if any
default occurs in the making of a payment due under any Permitted Investment, or
if a default occurs in any other performance required under any Permitted
Investment and the Special Servicer or the Master Servicer fails to deposit any
losses with respect to such Permitted Investment pursuant to Section 3.06(b),
the Trustee may and, subject to Section 8.02, upon the request of Holders of
Certificates entitled to not less than 25% of the Voting Rights allocated to any
Class, shall take such action as may be appropriate to enforce such payment or
performance, including the institution and prosecution of appropriate
proceedings.

     (d) Notwithstanding the investment of funds held in any Investment Account,
for purposes of the calculations hereunder, including, without limitation, the
calculation of the Available Distribution Amount, the amounts so invested shall
be deemed to remain on deposit in such Investment Account.

     SECTION 3.07   Maintenance of Insurance Policies; Errors and Omissions and
Fidelity Coverage.

     (a) The Master Servicer (with respect to Mortgage Loans and (to the extent
that the Trust Fund has an insurable interest) Companion Loans including
Specially Serviced

                                      124
<PAGE>

Mortgaged Loans) and the Special Servicer (with respect to REO Properties)
shall, consistent with the Servicing Standard, cause the Mortgagor to maintain,
to the extent required by the terms of the related Mortgage Loan Documents, or
if the Mortgagor does not maintain, shall itself maintain for each Mortgaged
Property all insurance coverage as is required under the related Mortgage;
provided that if and to the extent that any such Mortgage permits the holder
thereof any discretion (by way of consent, approval or otherwise) as to the
insurance coverage that the related Mortgagor is required to maintain, the
Master Servicer shall exercise such discretion in a manner consistent with the
Servicing Standard and subject to the terms of this Section 3.07; and provided
further that, if and to the extent that a Mortgage so permits, the related
Mortgagor shall be required to exercise its reasonable efforts to obtain the
required insurance coverage from Qualified Insurers and required insurance
coverage obtained by the Master Servicer shall be from Qualified Insurers. The
cost of any such insurance coverage obtained by either the Master Servicer or
the Special Servicer shall be a Servicing Advance to be paid by the Master
Servicer pursuant to Section 3.03. If not required under the terms of the
Mortgage or the Mortgage Loan Documents, the Special Servicer may require that
earthquake insurance be secured for one or more Mortgaged Properties at the
expense of the Trust Fund (including the Special Servicer's costs and expenses
incurred in obtaining such insurance). Subject to Section 3.17(a), the Special
Servicer shall also cause to be maintained for each REO Property no less
insurance coverage than was required of the Mortgagor under the related Mortgage
as of the Closing Date; provided that all such insurance shall be obtained from
Qualified Insurers. All such insurance policies maintained by the Master
Servicer or the Special Servicer (i) shall contain (if they insure against loss
to property and do not relate to an REO Property) a "standard" mortgagee clause,
with loss payable to the Trustee or the Master Servicer on behalf of the Trustee
(in the case of insurance maintained in respect of Mortgage Loans); (ii) shall
be in the name of the Special Servicer (in the case of insurance maintained in
respect of REO Properties), on behalf of the Trustee; (iii) shall be
non-cancelable without 30 days' prior written notice to the insured party; (iv)
shall include coverage in an amount not less than the lesser of (x) the full
replacement cost of the improvements securing a Mortgaged Property or REO
Property, as applicable, or (y) the outstanding principal balance owing on the
related Mortgage Loan or REO Loan, as applicable, and in any event, the amount
necessary to avoid the operation of any co-insurance provisions; (v) shall
include a replacement cost endorsement providing no deduction for depreciation
(unless such endorsement is not permitted under the related Mortgage Loan
Documents); (vi) shall include such other insurance, including, to the extent
available at commercially reasonable rates, earthquake insurance, where
applicable, as required under the applicable Mortgage or other Mortgage Loan
Documents; (vii) to the extent that the Mortgage or other Mortgage Loan
Documents specifically require terrorism coverage or the Mortgage requires the
related Mortgagor to carry "all risk" coverage, shall include terrorism
coverage, unless the failure to obtain such terrorism coverage constitutes an
Acceptable Insurance Default; and (viii) in each case such insurance shall be
issued by an insurer authorized under applicable law to issue such insurance.
Notwithstanding the foregoing, the Master Servicer or the Special Servicer shall
not be required to obtain, and shall not be in default hereunder for failing to
obtain, any insurance coverage that was previously required of the Mortgagor
under the related Mortgage if (a) such insurance is not available at any rate;
(b) such insurance is not available from a Qualified Insurer (provided that
Special Servicer shall obtain such insurance from the next highest rated insurer
offering such insurance at commercially reasonable rates); or (c) subject to the
prior approval of the Controlling Class Representative (which approval is deemed
granted if not denied within 10

                                      125
<PAGE>

Business Days after its receipt of the Master Servicer's or the Special
Servicer's request for such approval), such insurance is not available at
commercially reasonable rates and the subject hazards are not commonly insured
against by prudent owners of similar real properties in similar locales (but
only by reference to such insurance that has been obtained by such owners at
then current market rates). Any amounts collected by the Master Servicer or the
Special Servicer under any such policies (other than amounts to be applied to
the restoration or repair of the related Mortgaged Property or REO Property or
amounts to be released to the related Mortgagor, in each case subject to the
rights of any tenants and ground lessors, as the case may be, and in each case
in accordance with the terms of the related Mortgage and the Servicing Standard)
shall be deposited in the Certificate Account, subject to withdrawal pursuant to
Section 3.05(a), in the case of amounts received in respect of a Mortgage Loan
or a Companion Loan, or in the REO Account, subject to withdrawal pursuant to
Section 3.16(c), in the case of amounts received in respect of an REO Property.
Any cost incurred by the Master Servicer or the Special Servicer in maintaining
any such insurance shall not, for purposes hereof, including, without
limitation, calculating monthly distributions to Certificateholders, be added to
the unpaid principal balance of the related Mortgage Loan, notwithstanding that
the terms of such Mortgage Loan or Companion Loan, so permit.

     Notwithstanding the foregoing, with respect to the Mortgage Loans which
either (x) require the Mortgagor to maintain "all risk" property insurance (and
do not expressly permit an exclusion for terrorism) or (y) contain provisions
generally requiring the applicable Mortgagor to maintain insurance in types and
against such risks as the holder of such Mortgage Loan reasonably requires from
time to time in order to protect its interests, the Master Servicer will be
required to (A) use reasonable efforts to monitor whether the insurance policies
for the related Mortgaged Property contain Additional Exclusions, (B) request
the Mortgagor to either purchase insurance against the risks specified in the
Additional Exclusions or provide an explanation as to its reasons for failing to
purchase such insurance and (C) notify the Special Servicer if any insurance
policy contains Additional Exclusions or if any borrower fails to purchase the
insurance requested to be purchased by the Master Servicer pursuant to clause
(B) above. If the Special Servicer determines in accordance with the Servicing
Standard that such failure is not an Acceptable Insurance Default, the Special
Servicer shall notify the Master Servicer and the Master Servicer shall cause
such insurance to be maintained. Furthermore, the Special Servicer shall inform
the Rating Agencies as to such conclusions for those Mortgage Loans that (i)
have one of the ten (10) highest outstanding Stated Principal Balances of all of
the Mortgage Loans then included in the Trust Fund or (ii) comprise more than 5%
of the outstanding Stated Principal Balance of the Mortgage Loans then included
in the Trust Fund. During the period that the Special Servicer is evaluating the
availability of such insurance, the Master Servicer will not be liable for any
loss related to its failure to require the Mortgagor to maintain such insurance
and will not be in default of its obligations as a result of such failure and
the Master Servicer will not itself maintain such insurance or cause such
insurance to be maintained.

     (b) If the Master Servicer or the Special Servicer shall obtain and
maintain, or cause to be obtained and maintained, a blanket policy insuring
against hazard losses on all of the Mortgage Loans, the Companion Loans and/or
REO Properties that it is required to service and administer, then, to the
extent such policy (i) is obtained from a Qualified Insurer and (ii) provides
protection equivalent to the individual policies otherwise required, the Master
Servicer

                                      126
<PAGE>

or the Special Servicer, as the case may be, shall conclusively be deemed to
have satisfied its obligation to cause hazard insurance to be maintained on the
related Mortgaged Properties and/or REO Properties. In the event that the
Special Servicer causes any REO Property to be covered by such blanket policy,
the incremental cost of such insurance applicable to such REO Property (other
than any minimum or standby premium payable for such policy whether or not any
REO Property is covered thereby) shall be paid by the Master Servicer as a
Servicing Advance pursuant to Section 3.03. Such blanket policy may contain a
deductible clause (not in excess of a customary amount), in which case the
Master Servicer or the Special Servicer, as appropriate, shall, if there shall
not have been maintained on the related Mortgaged Property or REO Property a
hazard insurance policy complying with the requirements of Section 3.07(a), and
there shall have been one or more losses that would have been covered by such
policy, promptly deposit into the Certificate Account from its own funds the
amount not otherwise payable under the blanket policy because of such deductible
clause. The Master Servicer or the Special Servicer, as appropriate, shall
prepare and present, on behalf of itself, the Trustee, Certificateholders and if
applicable the Companion Loan Holders (except for the Fairfield Commons Pari
Passu Companion Loan as long as it is being serviced under the Series 2003-C5
Pooling and Servicing Agreement), claims under any such blanket policy in a
timely fashion in accordance with the terms of such policy.

     (c) Each of the Master Servicer and the Special Servicer shall at all times
during the term of this Agreement (or, in the case of the Special Servicer, at
all times during the term of this Agreement in which Specially Serviced Mortgage
Loans or REO Properties are part of the Trust Fund) keep in force a fidelity
bond with Qualified Insurers, such fidelity bond to be in such form and amount
as would permit it to be a qualified FNMA or FHLMC, whichever is greater,
seller-servicer of multifamily mortgage loans, or in such other form and amount
as would not cause the qualification, downgrading or withdrawal of any rating
assigned by any Rating Agency to the Certificates (as evidenced in writing from
each Rating Agency). Each of the Master Servicer and the Special Servicer shall
be deemed to have complied with the foregoing provision if an Affiliate thereof
has such fidelity bond coverage and, by the terms of such fidelity bond, the
coverage afforded thereunder extends to the Master Servicer or the Special
Servicer, as the case may be. Such fidelity bond shall provide for ten days'
written notice to the Trustee prior to any cancellation.

     Each of the Master Servicer and the Special Servicer shall at all times
during the term of this Agreement (or, in the case of the Special Servicer, at
all times during the term of this Agreement in which Specially Serviced Mortgage
Loans and/or REO Properties exist as part of the Trust Fund) also keep in force
with Qualified Insurers, a policy or policies of insurance covering loss
occasioned by the errors and omissions of its officers, employees and agents in
connection with its servicing obligations hereunder, which policy or policies
shall be in such form and amount as would permit it to be a qualified FNMA
seller-servicer of multifamily mortgage loans, or in such other form and amount
as would not cause the qualification, downgrade or withdrawal of any rating
assigned by any Rating Agency to the Certificates (as evidenced in writing from
each Rating Agency). Each of the Master Servicer and the Special Servicer shall
be deemed to have complied with the foregoing provisions if an Affiliate thereof
has such insurance and, by the terms of such policy or policies, the coverage
afforded thereunder extends to the Master Servicer or the Special Servicer, as
the case may be. Any such errors and omissions policy shall provide for ten
days' written notice to the Trustee prior to cancellation.

                                      127
<PAGE>

The Master Servicer and the Special Servicer shall each cause the Trustee to be
an additional loss payee on any policy currently in place or procured pursuant
to the requirements of this Section 3.07(c).

     For so long as the long-term debt obligations of the Master Servicer or
Special Servicer, as the case may be (or in the case of the initial Master
Servicer and Special Servicer, their respective direct parent), are rated at
least "A" or the equivalent by all of the Rating Agencies (or such lower rating
as will not result in qualification, downgrading or withdrawal of the ratings
then assigned to the Certificates, as evidenced in writing by the Rating
Agencies), such Person may self-insure with respect to the risks described in
this Section 3.07.

     (d) Within ninety (90) days of the Closing Date, with respect to each of
the Mortgage Loans identified on Exhibit J as being covered by an environmental
insurance policy, the Master Servicer (or the Special Servicer in the case of a
Specially Serviced Mortgage Loan) shall notify the insurer under such
environmental insurance policy and take all other action necessary for the
Trustee, on behalf of the Certificateholders, to be an insured (and for the
Master Servicer (or the Special Servicer in the case of a Specially Serviced
Mortgage Loan), on behalf of the Trust Fund, to make claims) under such
environmental insurance policy. In the event that the Master Servicer (or the
Special Servicer in the case of a Specially Serviced Mortgage Loan) has actual
knowledge of any event (an "Insured Environmental Event") giving rise to a claim
under any environmental insurance policy in respect of any Mortgage Loan covered
thereby, the Master Servicer (or the Special Servicer in the case of a Specially
Serviced Mortgage Loan) shall, in accordance with the terms of such
environmental insurance policy and the Servicing Standard, timely make a claim
thereunder with the appropriate insurer and shall take such other actions in
accordance with the Servicing Standard which are necessary under such
environmental insurance policy in order to realize the full value thereof for
the benefit of the Certificateholders (and to the extent consistent with the
Servicing Standard, the Companion Holders). Any legal fees, premiums or other
out-of-pocket costs incurred in connection with any such claim under an
environmental insurance policy shall be paid by the Master Servicer and shall be
reimbursable to it as a Servicing Advance. With respect to each environmental
insurance policy that relates to one or more Mortgage Loans, the Master Servicer
shall review and familiarize itself with the terms and conditions relating to
enforcement of claims and shall monitor the dates by which any claim must be
made or any action must be taken under such policy to realize the full value
thereof for the benefit of the Certificateholders (and to the extent consistent
with the Servicing Standard, the Companion Holders) in the event the Master
Servicer has actual knowledge of an Insured Environmental Event giving rise to a
claim under such policy.

     In the event that the Master Servicer (or the Special Servicer in the case
of a Specially Serviced Mortgage Loan) receives notice of any termination of any
environmental insurance policy that relates to one or more Mortgage Loans, the
Master Servicer (or the Special Servicer in the case of a Specially Serviced
Mortgage Loan) shall, within five Business Days after receipt of such notice,
notify the Special Servicer, the Controlling Class Representative, the Companion
Holders (in the case of an AB Mortgage Loan), the Rating Agencies and the
Trustee of such termination in writing. Upon receipt of such notice, the Master
Servicer with respect to non-Specially Serviced Mortgage Loans, and the Special
Servicer with respect to Specially Serviced Mortgage Loans, shall address such
termination in accordance with Section 3.07(a) in

                                      128
<PAGE>

the same manner as it would the termination of any other Insurance Policy
required under the related Mortgage Loan Documents. Any legal fees, premiums or
other out-of-pocket costs incurred in connection with a resolution of such
termination of an environmental insurance policy shall be paid by the Master
Servicer and shall be reimbursable to it as a Servicing Advance.

     SECTION 3.08    Enforcement of Alienation Clauses.

     (a) The Master Servicer (with respect to Mortgage Loans that are not
Specially Serviced Mortgage Loans) and the Special Servicer (with respect to
Specially Serviced Mortgage Loans), on behalf of the Trustee as the mortgagee of
record, shall enforce any "due-on-sale" or "due-on-encumbrance" clauses and any
other restrictions contained in the related Mortgage or other related loan
document on transfers or further encumbrances of the related Mortgaged Property
and on transfers of interests in the related Mortgagor, unless the Master
Servicer or the Special Servicer, as the case may be, has (i) determined, in its
reasonable judgment, that waiver of such restrictions would be in accordance
with the Servicing Standard and (ii) complied with the applicable requirements,
if any, of Section 6.11; provided that:

          (i) subject to the related Mortgage Loan Documents and applicable law,
     neither the Master Servicer nor the Special Servicer shall waive any right
     it has, or grant any consent it is otherwise entitled to withhold, in
     accordance with any related "due-on-encumbrance" clause under any Mortgage
     Loan that is a Significant Mortgage Loan, or if, taking into account
     existing debt on the subject Mortgaged Property and the proposed additional
     debt as if such total debt were a single Mortgage Loan, the Loan-to-Value
     Ratio is equal to or greater than 85% or the Debt Service Coverage Ratio is
     equal to or less than 1.2x, unless it receives prior written confirmation
     from each Rating Agency that such action would not result in an Adverse
     Rating Event with respect to any Class of rated Certificates (except that
     prior written confirmation from Fitch shall not be required unless the
     Mortgage Loan (A) is one of the ten largest Mortgage Loans in the Mortgage
     Pool or (B) when combined with any other Mortgage Loans made to Mortgagors
     that are affiliated to the related Mortgagor, constitutes one of the ten
     largest Mortgagor concentrations in the Mortgage Pool based on the
     then-current outstanding principal balance of all of the Mortgage Loans);

          (ii) if the affected Mortgage Loan is a Significant Mortgage Loan,
     then, subject to the related Mortgage Loan Documents and applicable law,
     neither the Master Servicer nor the Special Servicer shall waive any right
     it has, or grant any consent it is otherwise entitled to withhold, in
     accordance with any related "due-on-sale" clause under any Mortgage Loan
     until it has received written confirmation from each Rating Agency that
     such action would not result in an Adverse Rating Event with respect to any
     Class of rated Certificates (except that prior written confirmation from
     Fitch shall not be required unless the Mortgage Loan (A) is one of the ten
     largest Mortgage Loans in the Mortgage Pool or (B) when combined with any
     other Mortgage Loans made to Mortgagors that are affiliated to the related
     Mortgagor, constitutes one of the ten largest Mortgagor concentrations in
     the Mortgage Pool based on the then-current outstanding principal balance
     of all of the Mortgage Loans); provided, that, with respect to a waiver of
     a due-on-sale provision, in the event that such Mortgage Loan does not meet
     the

                                      129
<PAGE>

     criteria set forth in the prior sentence, and the Mortgage Loan Documents
     contain a requirement for Rating Agency approval, the Special Servicer may
     waive such requirement without Rating Agency approval in accordance with
     the Servicing Standard;

          (iii) subject to the related Mortgage Loan Documents and applicable
     law, the Master Servicer shall not waive any right it has, or grant any
     consent it is otherwise entitled to withhold, in accordance with any
     related "due-on-encumbrance" clause under any Mortgage Loan until it has
     delivered to the Special Servicer its recommendation and analysis of the
     request, together with a copy of the materials and information upon which
     such recommendation is based, and has received the consent of the Special
     Servicer (the giving of which consent shall be subject to the Servicing
     Standard and Section 6.11), which consent shall be deemed given if not
     denied in writing within 10 Business Days after receipt by the Special
     Servicer of the Master Servicer's written recommendation and analysis and
     any additional information requested by the Special Servicer or the
     Controlling Class Representative;

          (iv) subject to the related Mortgage Loan Documents and applicable
     law, the Master Servicer shall not waive any right it has, or grant any
     consent it is otherwise entitled to withhold, in accordance with any
     related "due-on-sale" clause under any Mortgage Loan until it has received
     the consent of the Special Servicer (the giving of which consent shall be
     subject to the Servicing Standard and Section 6.11), which consent shall be
     deemed given if not denied in writing within 10 Business Days of receipt by
     the Special Servicer of the Master Servicer's written recommendation and
     analysis and any additional information requested by the Special Servicer
     or the Controlling Class Representative;

          (v) subject to the related Mortgage Loan Documents and applicable law,
     neither the Master Servicer nor the Special Servicer shall waive any right
     it has, or grant any consent it is otherwise entitled to withhold, in
     accordance with any related "due-on-sale" or "due-on-encumbrance" clause
     under any Mortgage Loan, or approve the assumption of any Mortgage Loan,
     unless in any such case, all associated costs and expenses are covered
     without any expense to the Trust (it being understood and agreed that,
     except as expressly provided herein, neither the Master Servicer nor the
     Special Servicer shall be obligated to cover or assume any such costs or
     expenses); and

          (vi) neither the Master Servicer nor the Special Servicer shall (to
     the extent that it is within the control thereof to prohibit such event)
     consent to the transfer of any Mortgaged Property that secures a Crossed
     Group unless (i) all of the Mortgaged Properties securing such Crossed
     Group are transferred simultaneously by the respective Mortgagor or (ii) it
     obtains the consent of the Controlling Class Representative, which consent
     shall be deemed given if not denied in writing within 10 Business Days of
     receipt by the Controlling Class Representative of written notice of such
     action and all reasonably requested information related thereto (or, if no
     information is requested within ten (10) Business Days of receipt of
     written notice).

                                      130
<PAGE>

     In the case of any Mortgage Loan, the Master Servicer and the Special
Servicer shall each provide the other with all such information as each may
reasonably request in order to perform its duties under this section.

     In connection with any permitted assumption of any Mortgage Loan or waiver
of a "due-on-sale" or "due-on-encumbrance" clause thereunder, the Master
Servicer or the Special Servicer, as applicable, shall prepare all documents
necessary and appropriate for such purposes and shall coordinate with the
related Mortgagor for the due execution and delivery of such documents.

     (b) Notwithstanding any other provisions of this Section 3.08, the Master
Servicer with respect to Mortgage Loans which are not Specially Serviced
Mortgage Loans (without the Special Servicer's consent, but subject to
delivering notice to the Special Servicer and the Controlling Class
representative (and with respect to the 77 West Wacker Drive Mortgage Loan, the
WW Controlling Holder)) or the Special Servicer with respect to Specially
Serviced Mortgage Loans, as applicable, may grant, without any Rating Agency
confirmation as provided in paragraph (a) above, a Mortgagor's request for
consent to subject the related Mortgaged Property to an easement, right-of-way
or other similar agreement for utilities, access, parking, public improvements
or another purpose, and may consent to subordination of the related Mortgage
Loan to such easement, right-of-way or other similar agreement provided the
Master Servicer or the Special Servicer, as applicable, shall have determined in
accordance with the Servicing Standard that such easement, right-of-way or other
similar agreement shall not materially interfere with the then-current use of
the related Mortgaged Property, or the security intended to be provided by such
Mortgage, the related Mortgagor's ability to repay the Mortgage Loan, or
materially or adversely affect the value of such Mortgaged Property or cause the
Mortgage Loan to cease to be a qualified mortgage loan for REMIC purposes.

     SECTION 3.09    Realization Upon Defaulted Mortgage Loans; Required
Appraisals.

     (a) The Special Servicer shall, subject to Sections 3.09(b) through 3.09(d)
and Section 6.11, exercise reasonable efforts, consistent with the Servicing
Standard, to foreclose upon or exercise any power of sale contained in the
related Mortgage, obtain a deed-in-lieu of foreclosure, or otherwise acquire
title to the corresponding Mortgaged Property by operation of law or otherwise
in relation to such of the Mortgage Loans as come into and continue in default
and as to which no satisfactory arrangements can be made for collection of
delinquent payments, including, without limitation, pursuant to Section 3.20.
Subject to the second paragraph of Section 3.03(c), the Master Servicer shall
advance all costs and expenses (other than costs or expenses that would, if
incurred, constitute a Nonrecoverable Servicing Advance) incurred by the Special
Servicer in any such proceedings, and shall be entitled to reimbursement
therefor as provided in Section 3.05(a). Nothing contained in this Section 3.09
shall be construed so as to require the Special Servicer, on behalf of the Trust
Fund, to make a bid on any Mortgaged Property at a foreclosure sale or similar
proceeding that is in excess of the fair market value of such property, as
determined by the Special Servicer in accordance with the Servicing Standard and
in its reasonable and good faith judgment taking into account, as applicable,
among other factors, the period and amount of any delinquency on the affected
Mortgage Loan, the occupancy level and physical condition of the Mortgaged
Property or REO Property, the state of the local economy, the obligation to
dispose of any REO Property within the time period specified in

                                      131
<PAGE>

Section 3.16(a) and the results of any appraisal obtained pursuant to the
following sentence, all such bids to be made in a manner consistent with the
Servicing Standard. If and when the Master Servicer or the Special Servicer
deems it necessary and prudent for purposes of establishing the fair market
value of any Mortgaged Property securing a Defaulted Mortgage Loan, whether for
purposes of bidding at foreclosure or otherwise, it may, at the expense of the
Trust Fund, have an appraisal performed with respect to such property by an
Independent Appraiser or other expert in real estate matters; which appraisal
shall take into account, as applicable, among other factors, the period and
amount of any delinquency on the affected Mortgage Loan, the occupancy level and
physical condition of the Mortgaged Property or REO Property, the state of the
local economy and the obligation to dispose of any REO Property within the time
period specified in Section 3.16(a), including without limitation, any
environmental, engineering or other third party reports available, and other
factors that a prudent real estate appraiser would consider.

     With respect to each Required Appraisal Mortgage Loan, the Special Servicer
will be required to obtain a Required Appraisal (or with respect to any Mortgage
Loan with an outstanding principal balance, net of related unreimbursed advances
of principal, of less than $2,000,000, at the Special Servicer's option, an
internal valuation performed by the Special Servicer) within 60 days of a
Mortgage Loan becoming a Required Appraisal Mortgage Loan (unless an appraisal
meeting the requirements of a Required Appraisal was obtained for such Required
Appraisal Mortgage Loan within the prior 12 months and the Special Servicer has
no actual knowledge of a material adverse change in the condition of the related
Mortgaged Property in which case such appraisal may be a letter update of the
Required Appraisal) and thereafter shall obtain a Required Appraisal (or with
respect to any Mortgage Loan with an outstanding principal balance less than
$2,000,000, an internal valuation performed by the Special Servicer) once every
12 months (or sooner if the Special Servicer has actual knowledge of a material
adverse change in the condition of the related Mortgaged Property) if such
Mortgage Loan remains a Required Appraisal Mortgage Loan. The Special Servicer
shall deliver a copy of each Required Appraisal (or letter update or internal
valuation) to the Master Servicer, the Controlling Class Representative and the
Trustee within 10 Business Days of obtaining or performing such Required
Appraisal (or letter update or internal valuation). Subject to the second
paragraph of Section 3.03(c), the Master Servicer shall advance the cost of such
Required Appraisal; provided, however, that such expense will be subject to
reimbursement to the Master Servicer as a Servicing Advance out of the
Certificate Account pursuant to Section 3.05(a)(vi) and 3.05(a)(vii).

     Notwithstanding the foregoing, in no event shall the Master Servicer or the
Special Servicer obtain an appraisal of a Companion Loan pursuant to this
Section 3.09(a) to the extent the related AB Mortgage Loan has been paid in
full.

     (b) The Special Servicer shall not acquire any personal property pursuant
to this Section 3.09 unless either:

          (i) such personal property is incident to real property (within the
     meaning of Section 856(e)(1) of the Code) so acquired by the Special
     Servicer; or

                                      132
<PAGE>

          (ii) the Special Servicer shall have obtained an Opinion of Counsel
     (the cost of which may be withdrawn from the Certificate Account pursuant
     to Section 3.05(a)) to the effect that the holding of such personal
     property as part of the Trust Fund (to the extent not allocable to a
     Companion Loan) will not cause the imposition of a tax on any of 77 West
     Wacker Drive Loan REMIC, REMIC I or REMIC II under the REMIC Provisions or
     cause either of 77 West Wacker Drive Loan REMIC, REMIC I or REMIC II to
     fail to qualify as a REMIC at any time that any Certificate is outstanding.

     (c) Notwithstanding the foregoing provisions of this Section 3.09, neither
the Master Servicer nor the Special Servicer shall, on behalf of the Trustee,
obtain title to a Mortgaged Property by deed in lieu of foreclosure or
otherwise, or take any other action with respect to any Mortgaged Property, if,
as a result of any such action, the Trustee, on behalf of the Certificateholders
(or if applicable the holder of a related Companion Loan), could, in the
reasonable judgment of the Master Servicer or the Special Servicer, as the case
may be, made in accordance with the Servicing Standard, be considered to hold
title to, to be a "mortgagee-in-possession" of, or to be an "owner" or
"operator" of such Mortgaged Property within the meaning of CERCLA or any
comparable law (a "potentially responsible party"), unless (as evidenced by an
Officers' Certificate to such effect delivered to the Trustee that shall specify
all of the bases for such determination) the Special Servicer has previously
determined in accordance with the Servicing Standard, and based on an
Environmental Assessment of such Mortgaged Property performed by an Independent
Person who regularly conducts Environmental Assessments and performed within six
months prior to any such acquisition of title or other action (a copy of which
Environmental Assessment shall be delivered to the Trustee, the Controlling
Class Representative, the Master Servicer and, in the case of the Companion
Loans, each of the Companion Holders), that:

          (i) the Mortgaged Property is in compliance with applicable
     environmental laws and regulations or, if not, that it would maximize the
     recovery to the Certificateholders on a present value basis (the relevant
     discounting of anticipated collections that will be distributable to
     Certificateholders to be performed at the related Net Mortgage Rate) to
     acquire title to or possession of the Mortgaged Property and to take such
     actions as are necessary to bring the Mortgaged Property into compliance
     therewith in all material respects; and

          (ii) there are no circumstances or conditions present at the Mortgaged
     Property relating to the use, management or disposal of Hazardous Materials
     for which investigation, testing, monitoring, containment, clean-up or
     remediation could be required under any applicable environmental laws and
     regulations or, if such circumstances or conditions are present for which
     any such action could reasonably be expected to be required, that it would
     maximize the recovery to the Certificateholders on a present value basis
     (the relevant discounting of anticipated collections that will be
     distributable to Certificateholders to be performed at the related Net
     Mortgage Rate) to acquire title to or possession of the Mortgaged Property
     and to take such actions with respect to the affected Mortgaged Property.

     The Special Servicer shall undertake, in good faith, reasonable efforts to
make the determination referred to in the preceding paragraph and may
conclusively rely on the

                                      133
<PAGE>

Environmental Assessment referred to above in making such determination. The
cost of any such Environmental Assessment, as well as the cost of any remedial,
corrective or other further action contemplated by clause (i) and/or clause (ii)
of the preceding paragraph shall be at the expense of the Trust Fund (except to
the extent that such Additional Trust Fund Expense is payable out of the
proceeds of any Companion Loan pursuant to the related Intercreditor Agreement
and this Agreement and any Environmental Assessment ordered after the related AB
Mortgage Loan has been paid in full); and if any such Environmental Assessment
so warrants, the Special Servicer shall perform such additional environmental
testing as it deems necessary and prudent to determine whether the conditions
described in clauses (i) and (ii) of the preceding paragraph have been
satisfied, the cost of which shall be at the expense of the Trust Fund.

     (d) If the environmental testing contemplated by Section 3.09(c) above
establishes that any of the conditions set forth in clauses (i) and (ii) thereof
has not been satisfied with respect to any Mortgaged Property securing a
Defaulted Mortgage Loan and there is no breach of a representation or warranty
requiring repurchase under the Merrill Mortgage Loan Purchase Agreement, the
KeyBank Mortgage Loan Purchase Agreement or the JPMorgan Mortgage Loan Purchase
Agreement, as applicable, the Special Servicer shall take such action as is in
accordance with the Servicing Standard (other than proceeding against the
Mortgaged Property) and, at such time as it deems appropriate, may, on behalf of
the Trustee, release all or a portion of such Mortgaged Property from the lien
of the related Mortgage; provided that, if such Mortgage Loan has a then
outstanding principal balance of greater than $1 million, then prior to the
release of all or a portion of the related Mortgaged Property from the lien of
the related Mortgage, (i) the Special Servicer shall have notified the Rating
Agencies, the Trustee the Controlling Class Representative and the Master
Servicer in writing of its intention to so release all or a portion of such
Mortgaged Property and the bases for such intention, (ii) the Trustee shall have
notified the Certificateholders in writing of the Special Servicer's intention
to so release all or a portion of such Mortgaged Property and (iii) the Holders
of Certificates entitled to a majority of the Voting Rights shall have consented
to such release within 30 days of the Trustees's distributing such notice
(failure to respond by the end of such 30-day period being deemed consent).

     (e) The Special Servicer shall report to the Master Servicer, the
Controlling Class Representative and the Trustee and, in the case of the
Companion Loans, each of the Companion Holders, monthly in writing as to any
actions taken by the Special Servicer with respect to any Mortgaged Property
that represents security for a Defaulted Mortgage Loan as to which the
environmental testing contemplated in Section 3.09(c) above has revealed that
any of the conditions set forth in clauses (i) and (ii) thereof has not been
satisfied, in each case until the earlier to occur of satisfaction of all such
conditions and release of the lien of the related Mortgage on such Mortgaged
Property.

     (f) The Special Servicer shall have the right to determine, in accordance
with the Servicing Standard, the advisability of seeking to obtain a deficiency
judgment if the state in which the Mortgaged Property is located and the terms
of the Mortgage Loan permit such an action and shall, in accordance with the
Servicing Standard, seek such deficiency judgment if it deems advisable.

Files.

     (a) Upon the payment in full of any Mortgage Loan, or the receipt by the
Master Servicer of a notification that payment in full shall be escrowed in a
manner customary for such purposes, the Master Servicer shall promptly notify
the Trustee in writing, who shall release or cause the related Custodian to
release, by a certification (which certification shall be in the form of a
Request for Release in the form of Exhibit D-1 attached hereto and shall be
accompanied by the form of a release or discharge and shall include a statement
to the effect that all amounts received or to be received in connection with
such payment which are required to be deposited in the Certificate Account
pursuant to Section 3.04(a) have been or will be so deposited) of a Servicing
Officer (a copy of which certification shall be delivered to the Special
Servicer) and shall request delivery to it of the related Mortgage File. Upon
receipt of such certification and request, the Trustee shall release, or cause
any related Custodian to release, the related Mortgage File to the Master
Servicer and shall deliver to the Master Servicer such release or discharge,
duly executed. No expenses incurred in connection with any instrument of
satisfaction or deed of reconveyance shall be chargeable to the Certificate
Account or the Distribution Account.

     (b) If from time to time, and as appropriate for servicing or foreclosure
of any Mortgage Loan, the Master Servicer or the Special Servicer shall
otherwise require any Mortgage File (or any portion thereof), the Trustee, upon
request of the Master Servicer and receipt from the Master Servicer of a Request
for Release in the form of Exhibit D-1 attached

                                      135
<PAGE>

Servicer and receipt from the Special Servicer of a Request for Release in the
form of Exhibit D-2 attached hereto, shall release, or cause any related
Custodian to release, such Mortgage File (or portion thereof) to the Master
Servicer or the Special Servicer, as the case may be. Upon return of such

delivery to the Trustee of a certificate of a Servicing Officer of the Special
Servicer stating that such Mortgage Loan was liquidated and that all amounts
received or to be received in connection with such liquidation that are required
to be deposited into the Certificate Account pursuant to Section 3.04(a) have
been or will be so deposited, or that such Mortgage Loan has become an REO
Property, a copy of the Request for Release shall be released by the Trustee or
related Custodian to the Master Servicer or the Special Servicer, as applicable.

     (c) Within seven Business Days (or within such shorter period (but no less
than three Business Days) as execution and delivery can reasonably be
accomplished if the Special Servicer notifies the Trustee of an exigency) of the
Special Servicer's request therefor, the Trustee shall execute and deliver to
the Special Servicer (or the Special Servicer may execute and deliver in the
name of the Trustee based on a limited power of attorney issued in favor of the
Special Servicer pursuant to Section 3.01(b)), in the form supplied to the
Trustee, any court pleadings, requests for trustee's sale or other documents
stated by the Special Servicer to be reasonably necessary to the foreclosure or
trustee's sale in respect of a Mortgaged Property or REO Property or to any
legal action brought to obtain judgment against any Mortgagor on the Mortgage

remedies or rights provided by the Mortgage Note or Mortgage or otherwise
available at law or in equity or to defend any legal action or counterclaim
filed against the Trust Fund, the Master Servicer or the Special Servicer.
Together with such documents or pleadings, the Special Servicer shall deliver to
the Trustee a certificate of a Servicing Officer requesting that such pleadings
or documents be executed by the Trustee and certifying as to the reason such
documents or pleadings are required and that the execution and delivery thereof
by the Trustee will not invalidate or otherwise affect the lien of the Mortgage,
except for the termination of such a lien upon completion of the foreclosure or
trustee's sale.

     (d) From time to time, if the Fairfield Commons Total Loan is being
serviced pursuant to this Agreement, the Master Servicer or the Special
Servicer, as applicable, subject to the Fairfield Commons Intercreditor
Agreement and as is appropriate for servicing or foreclosure of the Fairfield
Commons Pari Passu Companion Loan, shall request the original of the related
Mortgage Note from the holder of the Fairfield Commons Pari Passu Companion
Loan.

     From time to time, if the Fairfield and Commons Total Loan is being
serviced pursuant to the Series 2003-C5 Pooling and Servicing Agreement,
pursuant to the terms of the Fairfield Commons Intercreditor Agreement, and the
Series 2003-C5 Master Servicer, the Series 2003-C5 Special Servicer or the
holder of the Fairfield Commons Pari Passu Companion Loan, as appropriate for
enforcing the terms of the Fairfield Commons Mortgage Loan, requests delivery to
it of the original Mortgage Note for the Fairfield Commons Mortgage Loan, then
the Trustee shall release or cause the release of such original Mortgage Note to
the requesting party or its designee. In connection with the release of the
original Mortgage Note for the Fairfield Commons Mortgage Loan in accordance
with the preceding sentence, the Trustee shall obtain such documentation as is
appropriate to evidence the holding by the Series 2003-C5 Master

                                      136
<PAGE>

Servicer, the Series 2003-C5 Special Servicer or the holder of the Fairfield
Commons Pari Passu Companion Loan of such original Mortgage Note as custodian on
behalf of and for the benefit of the Trustee.

     SECTION 3.11   Servicing Compensation.

     (a) As compensation for its activities hereunder, the Master Servicer shall
be entitled to receive the Master Servicing Fee with respect to each Mortgage
Loan (including each Specially Serviced Mortgage Loan (other than the Fairfield
Commons Pooled Mortgage Loan if it becomes a Specially Serviced Mortgage Loan)),
the Euless Square Subordinate Companion Loan, the Locust Grove Subordinate
Companion Loan, the Prindle Terrace Subordinate Companion Loan, and each REO
Loan (other than the Fairfield Commons Pooled Mortgage Loan if it becomes an REO
Loan). As to each such Mortgage Loan and REO Loan, the Master Servicing Fee
shall accrue at the related Master Servicing Fee Rate and on the same principal
amount respecting which the related interest payment due on such Mortgage Loan
or Companion Loan or deemed to be due on such REO Loan is computed and
calculated on the same interest accrual basis as that Mortgage Loan, which will
be either a 30/360 Basis or an Actual/360 Basis (or, in the event of a Principal
Prepayment in full or other Liquidation Event with respect to a Mortgage Loan,
such Companion Loan or an REO Loan, on the basis of the actual number of days to
elapse from and including the related Due Date to but excluding the date of such
Principal Prepayment or Liquidation Event in a month consisting of 30 days). The
Master Servicing Fee with respect to any Mortgage Loan, the Euless Square
Subordinate Companion Loan, the Locust Grove Subordinate Companion Loan, the
Prindle Terrace Companion Loan or any REO Loan shall cease to accrue if a
Liquidation Event occurs in respect thereof. Earned but unpaid Master Servicing
Fees shall be payable monthly on a loan-by-loan basis, from payments of interest
on each Mortgage Loan, the Euless Square Subordinate Companion Loan, the Locust
Grove Subordinate Companion Loan, the Prindle Terrace Companion Loan, as
applicable, and REO Revenues allocable as interest on each REO Loan. The Master
Servicer shall be entitled to recover unpaid Master Servicing Fees in respect of
any Mortgage Loan, the Euless Square Subordinate Companion Loan, the Locust
Grove Subordinate Companion Loan, the Prindle Terrace Companion Loan or any REO
Loan out of that portion of related Insurance Proceeds or Liquidation Proceeds
allocable as recoveries of interest, to the extent permitted by Section
3.05(a)(iii). The right to receive the Master Servicing Fee may not be
transferred in whole or in part except in connection with the transfer of all of
the Master Servicer's responsibilities and obligations under this Agreement or
the transfer of all or a portion of the Master Servicer's right to receive the
Excess Servicing Strip.

     Notwithstanding anything herein to the contrary, KRECM (and its successors
and assigns) may at its option assign or pledge to any third party or retain for
itself the Excess Servicing Strip (in whole but not in part); provided that any
assignee or pledgee of the Excess Servicing Strip must be a Qualified
Institutional Buyer or Institutional Accredited Investor (other than a Plan);
and provided, further, that no transfer, sale, pledge or other assignment of the
Excess Servicing Strip shall be made unless that transfer, sale, pledge or other
assignment is exempt from the registration and/or qualification requirements of
the Securities Act and any applicable state securities laws and is otherwise
made in accordance with the Securities Act and such state securities laws; and
provided, further, that in the event of any resignation or termination of KRECM
in its capacity as the Master Servicer, all or any portion of the Excess

                                      137
<PAGE>

Servicing Strip may be reduced by the Trustee to the extent reasonably necessary
(in the sole discretion of the Trustee) for the Trustee to obtain a qualified
successor Master Servicer (which successor may include the Trustee) that meets
the requirements of Section 6.04 and that requires market rate servicing
compensation that accrues at a per annum rate in excess of 0.01% per annum (one
basis point). KRECM and each holder of the Excess Servicing Strip desiring to
effect a transfer, sale, pledge or other assignment of the Excess Servicing
Strip shall, and KRECM hereby agrees, and each such holder of the Excess
Servicing Strip by its acceptance of the Excess Servicing Strip shall be deemed
to have agreed, in connection with any transfer of the Excess Servicing Strip
effected by such Person, to indemnify the Certificateholders, the Trust, the
Companion Holders, the Depositor, the Underwriters, the Trustee, the Fiscal
Agent, the Master Servicer, the Certificate Registrar and the Special Servicer
against any liability that may result if such transfer is not exempt from
registration and/or qualification under the Securities Act or other applicable
federal and state securities laws or is not made in accordance with such federal
and state laws or in accordance with the foregoing provisions of this paragraph.
By its acceptance of the Excess Servicing Strip, the holder thereof shall be
deemed to have agreed (i) to keep all information relating to the Trust and the
Trust Fund and made available to it by the Master Servicer confidential (except
as permitted pursuant to clause (iii) below or, in the case of the Master
Servicer, as contemplated hereby in the performance of its duties and
obligations hereunder), (ii) not to use or disclose such information in any
manner that could result in a violation of any provision of the Securities Act
or other applicable securities laws or that would require registration of the
Excess Servicing Strip or any Non-Registered Certificate pursuant to the
Securities Act, and (iii) not to disclose such information, and to cause its
officers, directors, partners, employees, agents or representatives not to
disclose such information, in any manner whatsoever, in whole or in part, to any
other Person other than such holder's auditors, legal counsel and regulators,
except to the extent such disclosure is required by law, court order or other
legal requirement or to the extent such information is of public knowledge at
the time of disclosure by such holder or has become generally available to the
public other than as a result of disclosure by such holder; provided, however,
that such holder may provide all or any part of such information to any other
Person who is contemplating an acquisition of the Excess Servicing Strip if, and
only if, such Person (x) confirms in writing such prospective acquisition and
(y) agrees in writing to keep such information confidential, not to use or
disclose such information in any manner that could result in a violation of any
provision of the Securities Act or other applicable securities laws or that
would require registration of the Excess Servicing Strip or any Non-Registered
Certificates pursuant to the Securities Act and not to disclose such
information, and to cause its officers, directors, partners, employees, agents
or representatives not to disclose such information, in any manner whatsoever,
in whole or in part, to any other Person other than such Persons' auditors,
legal counsel and regulators. From time to time following any transfer, sale,
pledge or assignment of the Excess Servicing Strip, the Person then acting as
the Master Servicer shall pay, out of each amount paid to such Master Servicer
as Master Servicing Fees with respect to any Mortgage Loan or REO Loan, as the
case may be, the portion of the Excess Servicing Strip attributable to such
Mortgage Loan or REO Loan to the holder of the Excess Servicing Strip within one
Business Day following the payment of such Master Servicing Fees to the Master
Servicer, in each case in accordance with payment instructions provided by such
holder in writing to the Master Servicer. The holder of the Excess Servicing
Strip shall not have any rights under this Agreement except as set forth in the
preceding sentences of this paragraph. The Master Servicer shall pay the Excess
Servicing Strip

                                      138
<PAGE>

to the holder of the Excess Servicing Strip (i.e., KRECM or any such third
party) at such time and to the extent the Master Servicer is entitled to receive
payment of its Master Servicing Fees hereunder, notwithstanding any resignation
or termination of KRECM hereunder (subject to reduction pursuant to the
preceding sentence).

     In the event that KRECM is terminated or resigns as Master Servicer, it
(and its successors and assigns) will be entitled to retain the Excess Servicing
Strip, except to the extent that any portion of such Excess Servicing Strip is
needed (as determined by the Trustee in its sole discretion) to compensate any
replacement Master Servicer for assuming the duties of KRECM under this
Agreement.

     (b) Additional master servicing compensation in the form of:

          (i) any and all late payment charges and Penalty Interest collected
     with respect to a performing Mortgage Loan;

          (ii) 50% of any and all assumption application fees, assumption fees,
     modification fees, extension fees, consent fees, release fees, waiver fees,
     fees paid in connection with defeasance and earn-out fees actually paid by
     a Mortgagor with respect to a performing Mortgage Loan (provided, however,
     that if the consent of the Special Servicer is not required pursuant to the
     terms of this Agreement in connection with the underlying servicing action,
     then the Master Servicer shall be entitled to receive 100% of such fees);

          (iii) any and all charges for beneficiary statements or demands,
     amounts collected for checks returned for insufficient funds and other loan
     processing fees actually paid by a Mortgagor with respect to a performing
     Mortgage Loan and, in the case of checks returned for insufficient funds,
     with respect to a Specially Serviced Mortgage Loan;

          (iv) any and all Prepayment Interest Excesses collected with respect
     to a Mortgage Loan, including a Specially Serviced Mortgage Loan (after
     deduction of the amounts required to be deposited by the Master Servicer in
     the Certificate Account for the related Distribution Date pursuant to
     Section 3.19(a) in connection with Prepayment Interest Shortfalls);

          (v) interest or other income earned on deposits in the Investment
     Accounts maintained by the Master Servicer (but only to the extent of the
     Net Investment Earnings, if any, with respect to any such Investment
     Account for each Collection Period and, further, in the case of a Servicing
     Account or Reserve Account, only to the extent such interest or other
     income is not required to be paid to any Mortgagor under applicable law or
     under the related Mortgage); and

          (vi) other customary charges;

may be retained by the Master Servicer and are not required to be deposited in
the Certificate Account; provided, that the Master Servicer's right to receive
late payment charges and Penalty Interest pursuant to clause (i) above shall be
limited to the portion of such items that have not

                                      139
<PAGE>

been applied to pay interest on Advances or Additional Trust Fund Expenses as
provided in Sections 3.03(d) and 4.03(d). The Master Servicer is entitled to the
above-described additional master servicing compensation with respect to the
Companion Loans to the extent not expressly prohibited under the related
Intercreditor Agreement; provided that, in no such case, shall the payment of
any such compensation reduce amounts otherwise payable to the Certificateholders
with respect to the related AB Mortgage Loan. Any of the amounts described in
clauses (i) through (v) that are collected by the Special Servicer shall be
promptly paid to the Master Servicer.

     Penalty Interest or late payment charges collected with respect to any
Mortgage Loan when the related Mortgage Loan is not a Specially Serviced
Mortgage Loan shall be additional compensation to the Master Servicer. The
Master Servicer shall be required to pay out of its own funds all expenses
incurred by it in connection with its servicing activities hereunder (including,
without limitation, payment of any amounts due and owing to any of its
Sub-Servicers and the premiums for any blanket policy insuring against hazard
losses pursuant to Section 3.07(b)), if and to the extent such expenses are not
payable directly out of the Certificate Account, and the Master Servicer shall
not be entitled to reimbursement therefor except as expressly provided in this
Agreement.

     As additional servicing compensation, the Master Servicer shall be entitled
to receive any Prepayment Interest Excesses collected with respect to the
Mortgage Loans, to the extent not required to offset any Prepayment Interest
Shortfalls pursuant to this Agreement.

     In respect of each Broker Strip Loan, the Master Servicer shall, on a
monthly basis, by the last day of the month following the month in which the
Master Servicer collected such Broker Strip, remit to the applicable broker set
forth on Exhibit Q hereto, the amount of the Broker Strip so collected.

     (c) As compensation for its activities hereunder, the Special Servicer
shall be entitled to receive the Special Servicing Fee with respect to each
Specially Serviced Mortgage Loan (except that no Special Servicing Fee shall
accrue on the Fairfield Pari Passu Companion Loan if it becomes a Specially
Serviced Mortgage Loan) and each REO Loan (other than the Fairfield Commons
Pooled Mortgage Loan if it becomes an REO Loan). As to each Specially Serviced
Mortgage Loan and REO Loan, the Special Servicing Fee shall accrue at the
Special Servicing Fee Rate and on the same principal amount respecting which the
related interest payment due on such Specially Serviced Mortgage Loan or deemed
to be due on such REO Loan is computed and calculated on an Actual/360 basis
(or, in the event of a Principal Prepayment in full or other Liquidation Event
with respect to a Mortgage Loan or REO Loan, on the basis of the actual number
of days to elapse from and including the related Due Date to but excluding the
date of such Principal Prepayment or Liquidation Event in a month consisting of
30 days). The Special Servicing Fee with respect to any Specially Serviced
Mortgage Loan or REO Loan shall cease to accrue as of the date a Liquidation
Event occurs in respect thereof or it becomes a Corrected Mortgage Loan. Earned
but unpaid Special Servicing Fees shall be payable monthly out of Liquidation
Proceeds, condemnation proceeds and then general collections on the Mortgage
Loans, Companion Loans and any REO Properties on deposit in the Certificate
Account pursuant to Section 3.05(a).

                                      140
<PAGE>

     As further compensation for its activities hereunder, the Special Servicer
shall be entitled to receive the Workout Fee with respect to each Corrected
Mortgage Loan (other than the Fairfield Commons Pooled Mortgage Loan), so long
as such loan remains a Corrected Mortgage Loan. As to each Corrected Mortgage
Loan, the Workout Fee shall be payable out of, and shall be calculated by
application of the Workout Fee Rate to, each collection of interest (other than
Additional Interest and Penalty Interest) and principal received on such
Mortgage Loan or Companion Loan for so long as it remains a Corrected Mortgage
Loan. The Workout Fee with respect to any Corrected Mortgage Loan will cease to
be payable if a Servicing Transfer Event occurs with respect thereto or if the
related Mortgaged Property becomes an REO Property; provided that a new Workout
Fee would become payable if and when such Mortgage Loan and, if applicable,
Companion Loan, again became a Corrected Mortgage Loan. If the Special Servicer
is terminated or resigns, it will retain the right to receive any and all
Workout Fees payable with respect to any Specially Serviced Mortgage Loan that
became a Corrected Mortgage Loan during the period that it acted as Special
Servicer and remained a Corrected Mortgage Loan at the time of its termination
or resignation or if the Special Servicer resolved the circumstances and/or
conditions (including by way of a modification of the related Mortgage Loan or
Companion Loan documents) causing the Mortgage Loan or Companion Loan to be a
Specially Serviced Loan, but the Mortgage Loan or Companion Loan had not as of
the time the Special Servicer is terminated or resigns become a Corrected
Mortgage Loan because the related borrower had not made three consecutive
monthly debt service payments (but had made the most recent monthly debt service
payment prior to the termination of the Special Servicer) and subsequently
becomes a Corrected Mortgage Loan as a result of making such three consecutive
payments. The successor Special Servicer will not be entitled to any portion of
those Workout Fees.

     In addition, with respect to each Specially Serviced Mortgage Loan and
Corrected Mortgage Loan (or Qualified Substitute Mortgage Loan substituted in
lieu thereof) (other than the Fairfield Commons Pooled Mortgage Loan) for which
it obtains a full or discounted payoff from the related Mortgagor, the Special
Servicer shall also be entitled to the Principal Recovery Fee (but in the case
of a Companion Loan, only to the extent expressly provided for in the related
Intercreditor Agreement) with respect to any Specially Serviced Mortgage Loan,
Corrected Mortgage Loan (other than the Fairfield Commons Pooled Mortgage Loan)
or REO Property (other than the Mortgaged Property relating to the Fairfield
Commons Pooled Mortgage Loan if it becomes an REO Property) as to which it
receives any Liquidation Proceeds or Insurance Proceeds or condemnation proceeds
and allocable as a recovery of principal, interest (other than Additional
Interest and Penalty Interest) and expenses in accordance with Section 3.02(b)
or the definition of "REO Loan", as applicable. The Principal Recovery Fee shall
be payable from Liquidation Proceeds, Insurance Proceeds or condemnation
proceeds. As to each Specially Serviced Mortgage Loan and REO Loan, the
Principal Recovery Fee shall be payable from, and will be calculated by
application of the Principal Recovery Fee Rate to the related payment or
proceeds. Notwithstanding the foregoing, no Principal Recovery Fee shall be
payable in connection with, or out of proceeds received in connection with the
purchase of any Mortgage Loan or REO Property by a Mortgage Loan Seller pursuant
to the Merrill Mortgage Loan Purchase Agreement, the KeyBank Mortgage Loan
Purchase Agreement or the JPMorgan Mortgage Loan Purchase Agreement due to a
Breach or a Document Defect, within the time period (or extension thereof)
provided for such repurchase or, if such repurchase occurs after such time
period, if the Mortgage Loan Seller was acting in good faith to resolve such
breach or

                                      141
<PAGE>

Document Defect, by the Majority Subordinate Certificateholder, the WW
Controlling Holder, the Companion Holder or the Special Servicer pursuant to
Section 3.18(c), Section 3.18(d), Section 3.18(e), Section 3.18(h), Section
3.18(m) or Section 3.26(d) or by the Master Servicer, the Special Servicer or
the Majority Subordinate Certificateholder pursuant to Section 9.01; and
provided further that no Principal Recovery Fee shall be payable (i) in
connection with a Periodic Payment received in connection with such Mortgage
Loan or (ii) to the extent a Workout Fee is payable concerning the Liquidation
Proceeds.

     The Special Servicer's right to receive the Special Servicing Fee, the
Workout Fee and the Principal Recovery Fee may not be transferred in whole or in
part except in connection with the transfer of all of the Special Servicer's
responsibilities and obligations under Sections 6.02, 6.04 and 6.09.

     (d) Additional servicing compensation in the form of: (i) all late payment
charges, Penalty Interest and (subject to Section 3.11(b)(ii)) assumption
application fees collected with respect to Specially Serviced Mortgage Loans
(other than the Fairfield Commons Total Loan), and (ii) one-hundred percent
(100%) of any assumption fee or modification fee to the extent actually paid by
a Mortgagor with respect to any Specially Serviced Mortgage Loan (other than the
Fairfield Commons Total Loan) and (subject to Section 3.11(b)(ii)) fifty percent
(50%) of any assumption fee to the extent actually paid by a Mortgagor with
respect to any non-Specially Serviced Mortgage Loan shall be retained by the
Special Servicer or promptly paid to the Special Servicer by the Master Servicer
and shall not be required to be deposited in the Certificate Account, provided
that the Special Servicer's right to receive late payment charges and Penalty
Interest pursuant to clause (i) above shall be limited to the portion of such
items that have not been applied to pay interest on Advances or Additional Trust
Fund Expenses and property inspection costs in respect of the related Mortgage
Loan as provided in Sections 3.03(d), 3.12(a) and 4.03(d) and shall be subject
to the allocations of such amounts in the related Intercreditor Agreement. The
Special Servicer shall also be entitled to additional servicing compensation in
the form of: (i) interest or other income earned on deposits in the REO Account,
if established, in accordance with Section 3.06(b) (but only to the extent of
the Net Investment Earnings, if any, with respect to the REO Account for each
Collection Period); and (ii) to the extent not required to be paid to any
Mortgagor under applicable law, any interest or other income earned on deposits
in the Servicing Accounts maintained by the Special Servicer. The Special
Servicer shall be required to pay out of its own funds all general and
administrative expenses incurred by it in connection with its servicing
activities hereunder, and the Special Servicer shall not be entitled to
reimbursement therefor except as expressly provided in Section 3.05(a) if and to
the extent such expenses are not payable directly out of the Certificate Account
or the REO Account.

     (e) If the Master Servicer or the Special Servicer collects an assumption
fee or an assumption application fee in connection with any transfer or proposed
transfer of any interest in a Mortgagor or a Mortgaged Property, then the Master
Servicer or the Special Servicer, as applicable, will apply that fee to cover
the costs and expenses associated with that transfer or proposed transfer that
are not otherwise paid by the related Mortgagor and that would otherwise be
payable or reimbursable out of the Trust Fund, including any Rating Agency fees
and expenses to the extent such fees and expenses are collectible under
applicable law and the Master Servicer or the Special Servicer, as appropriate,
fails to enforce such requirement in accordance

                                      142
<PAGE>

with the related Mortgage Loan Documents. Any remaining portion of such
assumption fee or of such assumption application fee will be applied as
additional compensation to the Master Servicer or the Special Servicer in
accordance with this Section 3.11. Neither the Master Servicer nor the Special
Servicer shall waive any assumption fee or assumption application fee, to the
extent it would constitute additional compensation for the other such party,
without the consent of such other party.

     SECTION 3.12   Property Inspections; Collection of Financial Statements;
Delivery of Certain Reports.

     (a) The Special Servicer shall perform or cause to be performed a physical
inspection of a Mortgaged Property as soon as practicable after a related
Mortgage Loan (other than the Fairfield Commons Total Loan so long as the
Fairfield Commons Pari Passu Companion Loan is included in the Series 2003-C5
Securitization) (i) becomes a Specially Serviced Mortgage Loan or (ii) the
related Debt Service Coverage Ratio set forth in the Comparative Financial
Status Report is below 1.0x, provided that such expense shall be reimbursable
first out of Penalty Interest and late payment charges otherwise payable to the
Special Servicer and the Master Servicer, then as an Additional Trust Fund
Expense (except to the extent that such Additional Trust Fund Expense is payable
out of the proceeds of any Companion Loan pursuant to the related Intercreditor
Agreement and this Agreement and any inspection occurring after the related AB
Mortgage Loan has been paid in full). In addition, after a Mortgage Loan becomes
a Specially Serviced Mortgage Loan, the Special Servicer shall perform or cause
to be performed a physical inspection of the related Mortgaged Property at least
once per calendar year, so long as such Mortgage Loan remains a Specially
Serviced Mortgage Loan. Beginning in 2004, the Master Servicer for each Mortgage
Loan other than a Specially Serviced Mortgage Loan or REO Loan, other than the
Fairfield Commons Pooled Mortgage Loan, so long as the Fairfield Commons Pari
Passu Companion Loan is included in the Series 2003-C5 Securitization, shall at
its expense perform or cause to be performed an inspection of all the Mortgaged
Properties at least once per calendar year, unless such Mortgaged Property has
been inspected in such calendar year by the Special Servicer or the Series
2003-C5 Special Servicer. The Special Servicer and the Master Servicer shall
each prepare (and, in the case of the Special Servicer, shall deliver to the
Master Servicer) a written report of each such inspection performed by it that
sets forth in detail the condition of the Mortgaged Property and that specifies
the existence of: (i) any sale, transfer or abandonment of the Mortgaged
Property of which it is aware, (ii) any change in the condition, occupancy or
value of the Mortgaged Property of which the Master Servicer or the Special
Servicer, as applicable, is aware and considers material, or (iii) any visible
waste committed on the Mortgaged Property of which the Master Servicer or the
Special Servicer, as applicable, is aware and considers material. The Master
Servicer shall within 45 days of the related inspection, deliver such reports
complete with any photographs taken thereof, to the Trustee, each other, and, in
an electronic format using the ARCap Naming Convention, to the Controlling Class
Representative and the related Companion Loan holder, if applicable (and in the
case of the 77 West Wacker Drive Mortgage Loan, the 77 West Wacker Drive
Operating Advisor) and the Trustee shall, subject to Section 3.15, make copies
of all such inspection reports available for review by Certificateholders and
Certificate Owners during normal business hours at the offices of the Trustee at
all times after Trustee's receipt thereof. Upon written request and at the
expense of the requesting party, the Trustee shall deliver copies of any such
inspection reports to Certificateholders and Certificate Owners and the related
Companion Loan holder, if

                                      143
<PAGE>

applicable. The Special Servicer shall have the right to inspect or cause to be
inspected (at its own expense) every calendar year any Mortgaged Property
related to a loan that is not a Specially Serviced Mortgage Loan, provided that
the Special Servicer obtains the approval of the Master Servicer prior to such
inspection, and provides a copy of such inspection to the Master Servicer; and
provided, further that the Master Servicer and the Special Servicer shall not
both inspect a Mortgaged Property that is not securing a Specially Serviced
Mortgage Loan in the same calendar year. If the Special Servicer or, in the case
of the Fairfield Commons Mortgage Loan, the Series 2003-C5 Master Servicer or
the Series 2003-C5 Special Servicer performs such inspection, such inspection
shall satisfy the Master Servicer's inspection obligations pursuant to this
paragraph (a).

     (b) The Special Servicer shall from time to time (and, in any event, upon
request) provide the Master Servicer with such information in its possession
regarding the Specially Serviced Mortgage Loans and REO Properties as may be
necessary for the Master Servicer to prepare each report and any supplemental
information to be provided by the Master Servicer to the Trustee. Without
limiting the generality of the foregoing, not later than 2:00 p.m. (New York
City time) on the Business Day following each Determination Date, beginning in
December 2003, the Special Servicer shall prepare and deliver or cause to be
delivered to the Master Servicer the CMSA Special Servicer Loan File that
contains the information called for in, or that will enable the Master Servicer
to produce, the CMSA files and reports required to be delivered by the Master
Servicer to the Trustee as described below, in each case with respect to all
Specially Serviced Mortgage Loans and the REO Properties.

     (c) The Master Servicer shall deliver to the Trustee (with a copy of all
pertinent information with respect to the Fairfield Commons Total Loan to the
holder of the Fairfield Commons Pari Passu Companion Loan unless it is included
in the Series 2003-C5 Securitization), no later than 4:00 p.m. New York City
time on the third Business Day prior to each Distribution Date beginning in
December 2003, the CMSA Loan Periodic Update File with respect to the subject
Distribution Date and notice of the Discount Rate applicable to each Principal
Prepayment received in the related Collection Period. Each Loan Periodic Update
File prepared by the Master Servicer shall be accompanied by a Monthly
Additional Report on Recoveries and Reimbursements. The preparation of each
Monthly Additional Report on Recoveries and Reimbursements shall constitute a
responsibility of the Master Servicer and shall not constitute a responsibility
of any other party. Notwithstanding anything in this Agreement that suggests
otherwise, the Master Servicer shall not be required to deliver a Monthly
Additional Report on Recoveries and Reimbursements (and no Loan Periodic Update
File need be accompanied by any such report) with respect to any Collection
Period for which all of the entries in the report would be "zero" or "not
applicable." The Master Servicer's responsibilities under this Section 3.12 with
respect to information to be provided by the Special Servicer with respect to
Specially Serviced Mortgage Loans and REO Properties shall be subject to the
satisfaction of the Special Servicer's obligations under Section 3.12(b), but
the failure of the Special Servicer to provide information required by it shall
not relieve the Master Servicer of its duties to provide the related reports,
absent such information. Notwithstanding the foregoing, because the Master
Servicer will not receive the Servicing Files until the Closing Date and will
not have sufficient time to review and analyze such Servicing Files before the
initial Distribution Date, the parties agree that the CMSA Loan Periodic Update
File required to be delivered by the Master Servicer in December 2003 will be
based solely upon information generated from actual

                                      144
<PAGE>

collections received by the Master Servicer and from information the Depositor
delivers or causes to be delivered to the Master Servicer (including but not
limited to information prepared by third party servicers of the subject Mortgage
Loans with respect to the period prior to the Closing Date). No later than 4:00
p.m. New York City time on each P&I Advance Date beginning in December 2003, the
Master Servicer shall deliver or cause to be delivered to the Trustee (with a
copy of all pertinent information with respect to the Fairfield Commons Total
Loan to the holder of the Fairfield Commons Pari Passu Companion Loan unless it
is included in the Series 2003-C5 Securitization) the following reports with
respect to the Mortgage Loans (and, if applicable, the related REO Properties,
providing the required information as of the related Determination Date): (i) a
CMSA Comparative Financial Status Report, (ii) a CMSA Delinquent Loan Status
Report; (iii) a CMSA Historical Loan Modification and Corrected Mortgage Loan
Report; (iv) a CMSA Historical Liquidation Report; (v) a CMSA REO Status Report;
(vi) a CMSA Servicer Watchlist; (vii) a CMSA Property File; (viii) a CMSA Loan
Set-up File, (ix) a CMSA Financial File, and (x) a CMSA Loan Level Reserve/LOC
Report. Such reports shall be in CMSA format (as in effect from time to time)
and shall be in an electronic format reasonably acceptable to both the Trustee
and the Master Servicer.

     (d) The Special Servicer will deliver to the Master Servicer the reports
set forth in Section 3.12(b) and this Section 3.12(d), and the Master Servicer
shall deliver to the Trustee the reports set forth in Section 3.12(c) in an
electronic format reasonably acceptable to the Special Servicer (c) the Master
Servicer and the Trustee. The Master Servicer may, absent manifest error,
conclusively rely on the reports to be provided by the Special Servicer pursuant
to Section 3.12(b) and this Section 3.12(d). The Trustee may, absent manifest
error, conclusively rely on the CMSA Loan Periodic Update File to be provided by
the Master Servicer pursuant to Section 3.12(c). In the case of information or
reports to be furnished by the Master Servicer to the Trustee pursuant to this
Section 3.12, to the extent that such information or reports are based on
information or reports to be provided by the Special Servicer pursuant to
Section 3.12(b) and this Section 3.12(d) and, to the extent that such reports
are to be prepared and delivered by the Special Servicer pursuant to Section
3.12(b) and this Section 3.12(d), the Master Servicer shall have no obligation
to provide such information to the Trustee until it has received such
information from the Special Servicer and the Master Servicer shall not be in
default hereunder due to a delay in providing information required by this
Section 3.12 to the extent caused by the Special Servicer's failure to timely
provide any information or report required under Section 3.12(b) and this
Section 3.12(d) of this Agreement, but the Master Servicer shall not be relieved
of its obligation to timely provide such reports absent the information not
provided by the Special Servicer as required by this Section 3.12.

     Commencing with respect to the calendar quarter ended December 31, 2003,
the Special Servicer, in the case of any Specially Serviced Mortgage Loan (other
than Fairfield Commons Pari Passu Companion Loan as long as the Fairfield
Commons Pari Passu Companion Loan is included in the Series 2003-C5
Securitization), and the Master Servicer, in the case of each performing
Mortgage Loan, shall make reasonable efforts to collect promptly from each
related Mortgagor quarterly and annual operating statements, budgets and rent
rolls of the related Mortgaged Property, and quarterly and annual financial
statements of such Mortgagor, whether or not delivery of such items is required
pursuant to the terms of the related Mortgage Loan Documents. In addition, the
Special Servicer shall cause quarterly and annual operating statements, budgets
and rent rolls to be regularly prepared in respect of each REO Property and

                                      145
<PAGE>

shall collect all such items promptly following their preparation. The Special
Servicer shall deliver images in suitable electronic media of all of the
foregoing items so collected or obtained by it to the Master Servicer within 30
days of its receipt thereof. The Master Servicer shall deliver at least
quarterly all items required to be delivered to it by the Special Servicer
pursuant to the second preceding sentence to the Controlling Class
Representative (and in the case of the 77 West Wacker Drive Mortgage Loan, the
77 West Wacker Drive Operating Advisor) and the Trustee in an imaged format in
accordance with the ARCap Naming Convention.

     The Master Servicer shall maintain a CMSA Operating Statement Analysis
Report with respect to each Mortgaged Property and REO Property related to each
Mortgage Loan. Within 60 days after receipt by the Master Servicer from the
related Mortgagor or otherwise, as to each performing Mortgage Loan and within
30 days after receipt by the Master Servicer from the Special Servicer, the
Series 2003-C5 Master Servicer or otherwise, as to the Fairfield Commons Pari
Passu Companion Loan, a Specially Serviced Mortgage Loan or an REO Property, of
any annual operating statements and rent rolls with respect to any Mortgaged
Property or REO Property, the Master Servicer shall, based upon such operating
statements or rent rolls, prepare (or, if previously prepared, update) the CMSA
Operating Statement Analysis Report for the subject Mortgaged Property or REO
Property. The Master Servicer shall remit in accordance with the ARCap Naming
Convention a copy of each CMSA Operating Statement Analysis Report prepared or
updated by it (promptly following initial preparation and each update thereof),
together with, if so requested and not already provided pursuant to this Section
3.12, the underlying operating statements and rent rolls, to the Controlling
Class Representative (and in the case of the 77 West Wacker Drive Mortgage Loan,
the 77 Wacker Drive Operating Advisor), the Trustee and the Special Servicer
(with a copy of all pertinent information with respect to the Fairfield Commons
Total Loan to the holder of the Fairfield Commons Pari Passu Companion Loan
unless it is included in the Series 2003-C5 Securitization). Within 60 days (or,
in the case of items received from the Special Servicer, the Series 2003-C5
Master Servicer, the Series 2003-C5 Special Servicer or otherwise with respect
to the Fairfield Commons Mortgage Loan, Specially Serviced Mortgage Loans and
REO Properties, 30 days) after receipt by the Master Servicer of any quarterly
or annual operating statements with respect to any Mortgaged Property or REO
Property, the Master Servicer shall prepare or update and forward to the
Trustee, the Special Servicer, the Controlling Class Representative (and in the
case of the 77 West Wacker Drive Mortgage Loan, the 77 Wacker Drive Operating
Advisor) a CMSA NOI Adjustment Worksheet using the same format and ARCap Naming
Convention as the CMSA Operating Statement Analysis Report for such Mortgaged
Property or REO Property, together with the related quarterly or annual
operating statements.

     (e) On or before the Closing Date, the Depositor shall provide to the
Master Servicer, the initial data (as of the respective Due Dates for the
Mortgage Loans in November 2003 or the most recent earlier date for which such
data is available) contemplated by the CMSA Loan Setup File, the CMSA Loan
Periodic Update File, the CMSA Operating Statement Analysis Report and the CMSA
Property File.

     (f) Notwithstanding any other provision in this Agreement, the Master
Servicer, and the Special Servicer shall deliver, and the Trustee shall make
available, to the Controlling Class Representative the reports (including the
Payments Received after Determination Date Report substantially in the form of

                                      146
<PAGE>

Exhibit N-2 and the Mortgage Loans Delinquent Report substantially in the form
of Exhibit N-4) and information set forth on Exhibit N-3 in the format and at
the times set forth therein.

     (g) Except with respect to delivery to the Special Servicer or the
Controlling Class Representative, which deliveries shall all be electronic, if
the Master Servicer or the Special Servicer is required to deliver any
statement, report or information under any provision of this Agreement, the
Master Servicer or Special Servicer, as the case may be, may satisfy such
obligation by (x) physically delivering a paper copy of such statement, report
or information, (y) delivering such statement, report or information in a
commonly used electronic format or (z) making such statement, report or
information available on such Master Servicer's Internet Website or the
Trustee's Internet Website, unless this Agreement expressly specifies a
particular method of delivery. Notwithstanding the foregoing, the Trustee may
request delivery in paper format of any statement, report or information
required to be delivered to the Trustee.

     (h) Notwithstanding any other provision in this Agreement, the failure of
the Master Servicer or Special Servicer to disclose any information otherwise
required to be disclosed by this Section 3.12, or that may otherwise be
disclosed pursuant to Sections 3.15 or Section 4.02, shall not constitute a
breach of this Agreement to the extent the Master Servicer or Special Servicer
so fails because such disclosure, in the reasonable belief of the Master
Servicer or Special Servicer, as the case may be, would violate any applicable
law or any provision of a Mortgage Loan Document prohibiting disclosure of
information with respect to the Mortgage Loans or Mortgaged Properties or would
constitute a waiver of the attorney-client privilege on behalf of the Trust. The
Master Servicer and Special Servicer may disclose any such information or any
additional information to any Person so long as such disclosure is consistent
with applicable law, the related Mortgage Loan Documents and the Servicing
Standard. The Master Servicer or the Special Servicer may affix to any
information provided by it under this Agreement any disclaimer it deems
appropriate in its discretion (without suggesting liability on the part of any
other party hereto).

     (i) The Master Servicer shall, contemporaneously with any related delivery
to the Trustee or the Special Servicer, as applicable, provide any reports that
contain information regarding the related Mortgaged Property or financial
information regarding the Mortgagor to the applicable Companion Holder (and with
respect to the 77 West Wacker Drive Mortgage Loan, the 77 West Wacker Drive
Operating Advisor). The Master Servicer shall, with the reasonable cooperation
of the other parties hereto, deliver to the applicable Companion Holder (and
with respect to the 77 West Wacker Drive Mortgage Loan, the 77 West Wacker Drive
Operating Advisor), to the extent not delivered pursuant to the prior sentence,
all documents, statements, reports and information with respect to the related
Companion Loan or the related Mortgaged Property as may be required under the
related Intercreditor Agreement.

     (j) Absent manifest error of which it has actual knowledge, none of the
Master Servicer or the Special Servicer shall be responsible for the accuracy or
completeness of any information supplied to it by a borrower or third party that
is included in any reports, statements, materials or information prepared or
provided by the Master Servicer or the Special Servicer, as applicable. The
Trustee shall not be responsible for the accuracy or completeness of any
information supplied to it for delivery pursuant to this Section. Neither the
Trustee, the Master Servicer nor the Special Servicer shall have any obligation
to verify the accuracy or

                                      147
<PAGE>

completeness of any information provided by a Mortgagor or third party. All
reports provided pursuant this Section 3.12 shall be in an electronic format
reasonable acceptable to both the Trustee and the Master Servicer.

     SECTION 3.13   Annual Statement as to Compliance.

     Each of the Master Servicer and the Special Servicer shall deliver to the
Trustee, the Controlling Class Representative (and in the case of the 77 West
Wacker Drive Mortgage Loan, the WW Controlling Holder), the Rating Agencies
(with a copy to the Depositor) and, if the Fairfield Commons Pari Passu
Companion Loan is included in the Series 2003-C5 Securitization, the holder of
the Fairfield Commons Pari Passu Companion Loan, and, in the case of the Special
Servicer, to the Master Servicer, on or before May 1 of each year, beginning May
1, 2004 (provided, that if the Trustee requires any such reports in connection
with any filing with the Securities and Exchange Commission, the Master Servicer
and the Special Servicer shall deliver such items on or before March 15 of each
year, beginning March 15, 2004), an Officers' Certificate stating, as to each
signer thereof, that (i) a review of the activities of the Master Servicer or
the Special Servicer, as the case may be, during the preceding calendar year and
of its performance under this Agreement has been made under such officer's
supervision, (ii) to the best of such officer's knowledge, based on such review,
the Master Servicer or the Special Servicer, as the case may be, has fulfilled
all of its obligations under this Agreement in all material respects throughout
such year, or, if there has been a material default in the fulfillment of any
such obligation, specifying each such material default known to such officer and
the nature and status thereof and (iii) the Master Servicer or the Special
Servicer, as the case may be, has received no notice regarding qualification, or
challenging the status, of 77 West Wacker Drive Loan REMIC, REMIC I or REMIC II
as a REMIC under the REMIC Provisions or of the Grantor Trust as a "Grantor
Trust" for income tax purposes under the Grantor Trust Provisions from the
Internal Revenue Service or any other governmental agency or body or, if it has
received any such notice, specifying the details thereof.

     SECTION 3.14   Reports by Independent Public Accountants.

     On or before May 1 of each year, beginning May 1, 2004 (provided, that if
the Trustee requires any such reports in connection with any filing with the
Securities and Exchange Commission, the Master Servicer and the Special Servicer
shall deliver such items on or before March 15 of each year, beginning March 15,
2004), each of the Master Servicer and the Special Servicer at its expense shall
cause a firm of Independent public accountants (which may also render other
services to the Master Servicer or the Special Servicer) that is a member of the
American Institute of Certified Public Accountants to furnish a statement to the
Trustee, Rating Agencies, Controlling Class Representative (and the WW
Controlling Holder), Depositor and, if the Fairfield Commons Pari Passu
Companion Loan is included in the Series 2003-C5 Securitization, the holder of
the Fairfield Commons Pari Passu Companion Loan and, in the case of the Special
Servicer, to the Master Servicer, to the effect that such firm has examined the
servicing operations of the Master Servicer or the Special Servicer, as the case
may be, for the previous calendar year (except that the first such report shall
cover the period from the Closing Date through December 31, 2003) and that, on
the basis of such examination, conducted substantially in compliance with USAP,
such firm confirms that the Master Servicer or the Special Servicer, as the case
may be, complied with the minimum servicing standards identified

                                      148
<PAGE>

in USAP, in all material respects, except for such significant exceptions or
errors in records that, in the opinion of such firm, the USAP requires it to
report. In rendering such statement, such firm may rely, as to matters relating
to direct servicing of mortgage loans by Sub-Servicers, upon comparable
statements for examinations conducted substantially in compliance with the
Uniform Single Audit Program for Mortgage Bankers (rendered within one year of
such statement) of independent public accountants with respect to the related
Sub-Servicer.

     SECTION 3.15   Access to Certain Information.

     (a) Upon ten days prior written notice, the Master Servicer (with respect
to the items in clauses (a), (b), (c), (d), (e), (f), (h) and (i) below, to the
extent such items are in its possession), the Special Servicer (with respect to
the items in clauses (d), (e), (f), (g), (h) and (i) below) and the Trustee
(with respect to the items in clause (b) and (i) below and to the extent any
other items are in its possession) shall make available at their respective

the case of the Trustee, at its Corporate Trust Office), during normal business
hours, or send to the requesting party, such party having been certified to the
Trustee or the Master Servicer, as applicable, in accordance with (a) and (b) in
the following paragraph, as appropriate, at the expense of such requesting party
(unless otherwise provided in this Agreement), for review by any Certificate
Owner or Certificateholder or any prospective transferee of any Certificate or

Loan and (i) any and all Officers' Certificates and other evidence delivered by
the Master Servicer or the Special Servicer, as the case may be, to support its
determination that any Advance was, or if made, would be, a Nonrecoverable
Advance including appraisals affixed thereto and any Required Appraisal prepared
pursuant to Section 3.09(a). Copies of any and all of the foregoing items will
be available from the Master Servicer, the Special Servicer or the Trustee, as
the case may be, upon request and shall be provided to any of the Rating
Agencies and the Controlling Class Representative (and with respect to the 77
West Wacker Drive Mortgage Loan, the WW Controlling Holder) at no cost pursuant
to their reasonable requests. The Master Servicer, Special Servicer and Trustee
may each satisfy its obligations under this Section 3.15(a) by making such items
available for review on its Internet Website with the use of a password.

                                      149
<PAGE>

     In connection with providing access to or copies of the items described in
the preceding paragraph pursuant to this Section 3.15, or with respect to the
Controlling Class Representative (and in the case of the 77 West Wacker Drive
Mortgage Loan, the WW Controlling Holder), in connection with providing access
to or copies of any items in accordance with this Agreement, the Trustee or the
Master Servicer, as applicable, shall require: (a) in the case of Certificate
Owners, Certificateholders and the Controlling Class Representative (and in the
case of the 77 West Wacker Drive Mortgage Loan, the WW Controlling Holder), a
confirmation executed by the requesting Person substantially in the form of
Exhibit I-1 hereto (or such other form as may be reasonably acceptable to the
Trustee or the Master Servicer, as applicable, and which may provide
indemnification for the Master Servicer or Trustee, as applicable) generally to
the effect that such Person is a beneficial holder of Book-Entry Certificates,
or a representative of a beneficial holder of Book-Entry Certificates, and,
subject to the last sentence of this paragraph, will keep such information
confidential (except that such Certificate Owner and the Controlling Class
Representative (and in the case of the 77 West Wacker Drive Mortgage Loan, the
WW Controlling Holder) may provide such information to any other Person that
holds or is contemplating the purchase of any Certificate or interest therein,
provided that such other Person confirms in writing such ownership interest or
prospective ownership interest and agrees to keep such information
confidential); and (b) in the case of a prospective purchaser of a Certificate
or an interest therein, confirmation executed by the requesting Person
substantially in the form of Exhibit I-2 hereto (or such other form as may be
reasonably acceptable to the Trustee or the Master Servicer, as applicable, and
which may provide indemnification for the Master Servicer or Trustee, as
applicable) generally to the effect that such Person is a prospective purchaser
of a Certificate or an interest therein, is requesting the information for use
in evaluating a possible investment in Certificates and, subject to the last
sentence of this paragraph, will otherwise keep such information confidential.
The Certificate Owners and Holders of the Certificates, by their acceptance
thereof, and the Controlling Class Representative (and in the case of the 77
West Wacker Drive Mortgage Loan, the WW Controlling Holder), by its acceptance
of its appointment, will be deemed to have agreed, subject to the last sentence
of this paragraph, to keep such information confidential (except that any Holder
may provide such information obtained by it to any other Person that holds or is
contemplating the purchase of any Certificate or interest therein, provided that
such other Person confirms in writing such ownership interest or prospective
ownership interest and agrees to keep such information confidential) and agrees
not to use such information in any manner that would violate federal, state or
local securities laws. Notwithstanding the foregoing, no Certificateholder,
Certificate Owner or prospective Certificateholder or Certificate Owner shall be
obligated to keep confidential any information received from the Trustee or the
Master Servicer, as applicable, pursuant to this Section 3.15 that has
previously been made available without a password via the Trustee's or the
Master Servicer's, as applicable, Internet Website or has previously been filed
with the Commission, and the Trustee or the Master Servicer, as applicable,
shall not require either of the certifications contemplated by the second
preceding sentence in connection with providing any information pursuant to this
Section 3.15 that has previously been made available without a password via the
Trustee's or the Master Servicer's, as applicable, Internet Website or has
previously been filed with the Commission.

     Each of the Master Servicer and the Special Servicer shall afford to the
Trustee, the Rating Agencies and the Depositor, and to the OTS, the FDIC, the
Federal Reserve Board and any other banking or insurance regulatory authority
that may exercise authority over any

                                      150
<PAGE>

Certificateholder, access to any records regarding the Mortgage Loans and the
servicing thereof within its control, except to the extent it is prohibited from
doing so by applicable law or contract or to the extent such information is
subject to a privilege under applicable law to be asserted on behalf of the
Certificateholders. Such access shall be afforded only upon reasonable prior
written request and during normal business hours at the offices of the Master
Servicer or the Special Servicer, as the case may be, designated by it.

     The Trustee, the Master Servicer, the Special Servicer and the Underwriters
may require payment from the Certificateholder or Certificate Owner of a sum
sufficient to cover the reasonable costs and expenses of providing any such
information or access pursuant to this Section 3.15 to, or at the request of,
the Certificateholders or Certificate Owners or prospective transferees,
including, without limitation, copy charges and, in the case of
Certificateholders or Certificate Owners requiring on site review in excess of
three Business Days, reasonable fees for employee time and for space.

     (b) The Trustee shall, and the Master Servicer may but is not required to,
make available each month to any interested party (i) the Distribution Date
Statement via their respective Internet Websites, and (ii) as a convenience for
interested parties this Agreement on their respective Internet Websites. In
addition, the Trustee shall make available each month, on each Distribution
Date, the Unrestricted Servicer Reports, the updated collection report, the CMSA
Delinquent Loan Status Report, the CMSA REO Status Report, the CMSA Loan
Periodic Update File, the CMSA Loan Setup File, the CMSA Bond File, and the CMSA
Collateral Summary File to any interested party on its Internet Website. The
Trustee shall, upon request, make available each month, on each Distribution
Date, (i) the Restricted Servicer Reports, (ii) the CMSA Servicer Watch List,
the CMSA Operating Statement Analysis Report, the CMSA NOI Adjustment Worksheet
and the CMSA Comparative Financial Status Report, and (iii) the CMSA Property

Internet Website with the use of a password (or other comparable restricted

month, on the Distribution Date, the interim Delinquent Loan Status Report to
any interested party on its Internet Website.

     The Master Servicer may, but is not required to, make available each month
via its Internet Website to any Privileged Person, with the use of a password
provided by the Master Servicer, the reports and files comprising the CMSA
Investor Reporting Package.

     (c) In connection with providing access to the Trustee's Internet Website
or the Master Servicer's Internet Website, the Trustee or the Master Servicer,
as applicable, may require registration and the acceptance of a disclaimer and
may otherwise adopt reasonable rules and procedures that may include, to the
extent the Master Servicer or Trustee, as applicable, deems necessary or
appropriate, conditioning access on the execution and delivery of an agreement
(which may be in the form of Exhibit I-1 or I-2) governing the availability, use
and disclosure of such information and providing indemnification to the Master
Servicer or Trustee, as applicable, for any liability or damage that may arise
therefrom.

     The Master Servicer and Trustee may, in accordance with such reasonable
rules and procedures as each may adopt (including conditioning access on the
execution and delivery of an agreement (which may be in the form of Exhibit I-1
or I-2) governing the availability, use

                                      151
<PAGE>

and disclosure of information and providing indemnification to the Master
Servicer or Trustee, as applicable, for any liability or damage that may arise
therefrom), also make available, through its Internet Website or otherwise, any
additional information relating to the Mortgage Loans, the Mortgaged Properties
or the Mortgagors for review by any Persons to whom the Master Servicer or
Trustee, as applicable, believes such disclosure is appropriate, in each case
except to the extent doing so is prohibited by applicable law or by the related
Mortgage Loan (in the case of Trustee, if it has actual knowledge of such
prohibition by the related Mortgage Loan).

     Notwithstanding anything in this Agreement to the contrary, the Master
Servicer and the Trustee may withhold (other than with respect to items required
to be delivered under this Agreement to the Controlling Class Representative
(and in the case of the 77 West Wacker Drive Mortgage Loan, the WW Controlling
Holder)) any information not yet included in a Form 8-K filed with the
Commission or otherwise made publicly available with respect to which the
Trustee or the Master Servicer has determined that such withholding is
appropriate.

     Any transmittal of information by the Master Servicers or the Trustee to
any Person other than the Rating Agencies or the Depositor may be accompanied by
a letter containing the following provision:

     "By receiving the information set forth herein, you hereby acknowledge and
     agree that the United States securities laws restrict any person who
     possesses material, non-public information regarding the Trust that issued
     Merrill Lynch Mortgage Trust 2003-KEY1, Commercial Mortgage Pass-Through
     Certificates, Series 2003-KEY1, from purchasing or selling such
     Certificates in circumstances where the other party to the transaction is
     not also in possession of such information. You also acknowledge and agree
     that such information is being provided to you for the purposes of, and
     such information may be used only in connection with, evaluation by you or
     another Certificateholder or prospective purchaser of such Certificates or
     beneficial interest therein."

     (d) If three or more Holders or the Controlling Class Representative
(hereinafter referred to as "Applicants" with a single Person which (together
with its Affiliates) is the Holder of more than one Class of Certificates being
viewed as a single Applicant for these purposes) apply in writing to the
Trustee, and such application states that the Applicants' desire to communicate
with other Holders with respect to their rights under this Agreement or under
the Certificates and is accompanied by a copy of the communication which such
Applicants propose to transmit, then the Trustee shall, within five Business
Days after the receipt of such application, send, at the Applicants' expense,
the written communication proffered by the Applicants to all Certificateholders
at their addresses as they appear in the Certificate Register.

     (e) The Master Servicer and the Special Servicer shall not be required to
confirm, represent or warrant the accuracy or completeness of any other Person's
information or report included in any communication from the Master Servicer or
the Special Servicer under this Agreement. None of the Master Servicer, the
Special Servicer or the Trustee shall be liable for the dissemination of
information in accordance with the terms of this Agreement. The

                                      152
<PAGE>

Trustee makes no representations or warranties as to the accuracy or
completeness of any report, document or other information made available on the
Trustee's Website and assumes no responsibility therefor. In addition, the
Trustee, the Master Servicer and the Special Servicer may disclaim
responsibility for any information distributed by the Trustee, the Master
Servicer or the Special Servicer, respectively, for which it is not the original
source.

     SECTION 3.16   Title to REO Property; REO Account.

     (a) If title to any REO Property is acquired, the deed or certificate of
sale shall be issued to the Trustee or its nominee on behalf of the
Certificateholders and if applicable, the Companion Holder, as their interests
shall appear. The Special Servicer, on behalf of the Trust Fund, shall sell any
REO Property as soon as practicable in accordance with the Servicing Standard,
but prior to the end of the third year following the calendar year in which
REMIC I or the 77 West Wacker Drive Loan REMIC, as applicable, acquires
ownership of such REO Property for purposes of Section 860G(a)(8) of the Code,
unless the Special Servicer either (i) applies for, more than sixty days prior
to the end of such third succeeding year, and is granted an extension of time
(an "REO Extension") by the Internal Revenue Service to sell such REO Property
or (ii) obtains for the Trustee an Opinion of Counsel, addressed to the Trustee,
the Special Servicer and the Master Servicer, to the effect that the holding by
REMIC I or the 77 West Wacker Drive Loan REMIC, as applicable, of such REO
Property subsequent to the end of such third succeeding year will not result in
the imposition of taxes on "prohibited transactions" (as defined in Section 860F
of the Code) on either of 77 West Wacker Drive Loan REMIC, REMIC I or REMIC II
or cause either of 77 West Wacker Drive Loan REMIC, REMIC I or REMIC II to fail
to qualify as a REMIC at any time that any Certificates are outstanding. If the
Special Servicer is granted the REO Extension contemplated by clause (i) of the
immediately preceding sentence or obtains the Opinion of Counsel contemplated by
clause (ii) of the immediately preceding sentence, the Special Servicer shall
sell such REO Property within such extended period as is permitted by such REO
Extension or such Opinion of Counsel, as the case may be. Any expense incurred
by the Special Servicer in connection with its obtaining the REO Extension
contemplated by clause (i) of the second preceding sentence or its obtaining the
Opinion of Counsel contemplated by clause (ii) of the second preceding sentence,
shall first be payable from the related REO Account to the extent of available
funds and then be a Servicing Advance by the Master Servicer pursuant to Section
3.03(c).

     (b) The Special Servicer shall segregate and hold all funds collected and
received in connection with any REO Property separate and apart from its own
funds and general assets. If an REO Acquisition shall occur, the Special
Servicer shall establish and maintain one or more accounts (collectively, the
"REO Account"), held on behalf of the Trustee in trust for the benefit of the
Certificateholders, and if applicable, the Companion Holders, as their interests
shall appear, for the retention of revenues and other proceeds derived from each
REO Property. The REO Account shall be an Eligible Account. The Special Servicer
shall deposit, or cause to be deposited, in the REO Account, upon receipt, all
REO Revenues, Insurance Proceeds and Liquidation Proceeds received in respect of
an REO Property within 2 Business Days of receipt. Funds in the REO Account may
be invested in Permitted Investments in accordance with Section 3.06. The
Special Servicer shall be entitled to make withdrawals from the REO Account to
pay itself, as additional servicing compensation in accordance with Section
3.11(d), interest and investment income earned in respect of amounts held in the
REO Account as provided in Section

                                      153
<PAGE>

3.06(b) (but only to the extent of the Net Investment Earnings with respect to
the REO Account for any Collection Period). The Special Servicer shall give
written notice to the Trustee and the Master Servicer of the location of the REO
Account when first established and of the new location of the REO Account prior
to any change thereof.

     (c) The Special Servicer shall withdraw from the REO Account funds
necessary for the proper operation, management, leasing, maintenance and
disposition of any REO Property, but only to the extent of amounts on deposit in
the REO Account relating to such REO Property (including any monthly reserve or
escrow amounts necessary to accumulate sufficient funds for taxes, insurance and
anticipated capital expenditures (the "Impound Reserve")). On each Determination
Date, the Special Servicer shall withdraw from the REO Account and deposit into
the Certificate Account or deliver to the Master Servicer or such other Person
as may be directed by the Master Servicer (which shall deposit such amounts into
the Certificate Account) the aggregate of all amounts received in respect of
each REO Property during the most recently ended Collection Period, net of any
withdrawals made out of such amounts pursuant to the preceding sentence;
provided that, in addition to the Impound Reserve, the Special Servicer may
retain in the REO Account such portion of proceeds and collections as may be
necessary to maintain a reserve of sufficient funds for the proper operation,
management, leasing, maintenance and disposition of the related REO Property
(including, without limitation, the creation of a reasonable reserve for
repairs, replacements, necessary capital improvements and other related
expenses).

     (d) The Special Servicer shall keep and maintain separate records, on a
property-by-property basis, for the purpose of accounting for all deposits to,
and withdrawals from, the REO Account pursuant to Section 3.16(b) or (c). The
Special Servicer shall provide the Master Servicer any information with respect
to the REO Account as is reasonably requested by the Master Servicer.

     SECTION 3.17   Management of REO Property.

     (a) Prior to the acquisition of title to a Mortgaged Property, the Special
Servicer shall review the operation of such Mortgaged Property and consult with
the Trustee, or any person appointed by the Trustee to act as tax administrator
to determine the nature of the income that would be derived from such property
if it were acquired by the Trust Fund. If the Special Servicer determines from
such review that:

          (i) None of the income from Directly Operating such Mortgaged Property
     would be subject to tax as "net income from foreclosure property" within
     the meaning of the REMIC Provisions and Section 857(b)(4)(B) of the Code
     (such tax referred to herein as an "REO Tax"), and the Special Servicer
     does not engage in any of the activities described in the definition of
     "Directly Operate" that would cause the REO Property to cease to qualify as
     "foreclosure property" within the meaning of Section 860G(a)(8) of the
     Code, then such Mortgaged Property may be Directly Operated by the Special
     Servicer as REO Property;

          (ii) Directly Operating such Mortgaged Property as an REO Property
     could result in income from such property that would be subject to an REO
     Tax, but that

                                      154
<PAGE>

     a lease of such property to another party to operate such property, or the
     performance of some services by an Independent Contractor with respect to
     such property, or another method of operating such property would not
     result in income subject to an REO Tax, then the Special Servicer may
     (provided, that in the good faith and reasonable judgment of the Special
     Servicer, such alternative is commercially feasible and would result in a
     greater net recovery on a present value basis than earning income subject
     to an REO Tax) acquire such Mortgaged Property as REO Property and so lease
     or manage such REO Property; or

          (iii) It is reasonable to believe that Directly Operating such
     property as REO Property could result in income subject to an REO Tax and
     that such method of operation is commercially feasible and would result in
     a greater net recovery on a present value basis than leasing or other
     method of operating the REO Property that would not incur an REO Tax, the
     Special Servicer shall deliver to the REMIC Administrator, in writing, a
     proposed plan (the "Proposed Plan") to manage such property as REO
     Property. Such plan shall include potential sources of income, and to the
     extent commercially feasible, estimates of the amount of income from each
     such source. Within a reasonable period of time after receipt of such plan,
     the REMIC Administrator shall consult with the Special Servicer and shall
     advise the Special Servicer of the REMIC Administrator's federal income tax
     reporting position with respect to the various sources of income that the
     Trust Fund would derive under the Proposed Plan. In addition, the REMIC
     Administrator shall (to the extent reasonably possible) advise the Special
     Servicer of the estimated amount of taxes that the Trust Fund would be
     required to pay with respect to each such source of income. After receiving
     the information described in the two preceding sentences from the REMIC
     Administrator, the Special Servicer shall either (A) implement the Proposed
     Plan (after acquiring the respective Mortgaged Property as REO Property) or
     (B) manage such property in a manner that would not result in the
     imposition of an REO Tax on the income derived from such property. All of
     the REMIC Administrator's expenses (including any fees and expenses of
     counsel or other experts reasonably retained by it) incurred pursuant to
     this section shall be reimbursed to it from the Trust Fund in accordance
     with Section 10.01(e).

     The Special Servicer's decision as to how each REO Property shall be
managed shall be based on the Servicing Standard and in any case on the good
faith and reasonable judgment of the Special Servicer as to which means would be
in the best interest of the Certificateholders by maximizing (to the extent
commercially feasible and consistent with Section 3.17(b)) the net after-tax REO
Revenues received by the Trust Fund with respect to such property and, to the
extent consistent with the foregoing, in the same manner as would prudent
mortgage loan servicers operating acquired mortgaged property comparable to the
respective Mortgaged Property. Both the Special Servicer and the REMIC
Administrator may, at the expense of the Trust Fund payable pursuant to Section
3.05(a)(xiii) consult with counsel.

     (b) If title to any REO Property is acquired, the Special Servicer shall
manage, conserve and protect such REO Property for the benefit of the
Certificateholders (and, if applicable, the related Companion Holder) solely for
the purpose of its prompt disposition and sale in a manner that does not and
will not cause such REO Property to fail to qualify as "foreclosure property"
within the meaning of Section 860G(a)(8) of the Code or either result in

                                      155
<PAGE>

the receipt by either the 77 West Wacker Drive Loan REMIC or REMIC I of any
"income from non-permitted assets" within the meaning of Section 860F(a)(2)(B)
of the Code or result in an Adverse REMIC Event. Subject to the foregoing,
however, the Special Servicer shall have full power and authority to do any and
all things in connection therewith as are consistent with the Servicing Standard
and, consistent therewith, shall withdraw from the REO Account, to the extent of
amounts on deposit therein with respect to any REO Property, funds necessary for
the proper operation and management, maintenance and disposition of such REO
Property, including without limitation:

          (i) all insurance premiums due and payable in respect of such REO
     Property;

          (ii) all real estate taxes and assessments in respect of such REO
     Property that may result in the imposition of a lien thereon;

          (iii) any ground rents in respect of such REO Property; and

          (iv) all costs and expenses necessary to maintain, lease, sell,
     protect, manage and restore such REO Property.

     To the extent that amounts on deposit in the REO Account in respect of any
REO Property are insufficient for the purposes set forth in the preceding
sentence with respect to such REO Property, the Master Servicer, subject to
Section 3.03(c), shall make Servicing Advances in such amounts as are necessary
for such purposes unless (as evidenced by an Officers' Certificate delivered to
the Trustee) the Master Servicer would not make such advances if the Master
Servicer owned such REO Property or the Master Servicer determines, in
accordance with the Servicing Standard, that such payment would be a
Nonrecoverable Advance; provided, however, that the Master Servicer may make any
such Servicing Advance without regard to recoverability if it is a necessary fee
or expense incurred in connection with the defense or prosecution of legal
proceedings.

     (c) Unless Section 3.17 (a)(i) applies, the Special Servicer shall contract
with any Independent Contractor for the operation and management of any REO
Property, provided that:

          (i) the terms and conditions of any such contract may not be
     inconsistent herewith and shall reflect an agreement reached at arm's
     length;

          (ii) the fees of such Independent Contractor (which shall be expenses
     of the Trust Fund) shall be reasonable and customary in consideration of
     the nature and locality of the REO Property;

          (iii) except as permitted under Section 3.17(a), any such contract
     shall require, or shall be administered to require, that the Independent
     Contractor, in a timely manner, (A) pay all costs and expenses incurred in
     connection with the operation and management of such REO Property,
     including, without limitation, those listed in Section 3.17(b) above, and
     (B) except to the extent that such revenues are derived from any services
     rendered by the Independent Contractor to tenants of the REO Property that
     are

                                      156
<PAGE>

     not customarily furnished or rendered in connection with the rental of real
     property (within the meaning of Section 1.856-4(b)(5) of the Treasury
     Regulations or any successor provision), remit all related revenues
     collected (net of its fees and such costs and expenses) to the Special
     Servicer upon receipt;

          (iv) none of the provisions of this Section 3.17(c) relating to any
     such contract or to actions taken through any such Independent Contractor
     shall be deemed to relieve the Special Servicer of any of its duties and
     obligations hereunder with respect to the operation and management of any
     such REO Property; and

          (v) the Special Servicer shall be obligated with respect thereto to
     the same extent as if it alone were performing all duties and obligations
     in connection with the operation and management of such REO Property.

The Special Servicer shall be entitled to enter into any agreement with any
Independent Contractor performing services for it related to its duties and
obligations hereunder for indemnification of the Special Servicer by such
Independent Contractor, and nothing in this Agreement shall be deemed to limit
or modify such indemnification. No agreement entered into pursuant to this
Section 3.17(c) shall be deemed a Sub-Servicing Agreement for purposes of
Section 3.22.

     SECTION 3.18   Resolution of Defaulted Mortgage Loans and REO Properties.

     (a) The Master Servicer, the Special Servicer or the Trustee may sell or
purchase, or permit the sale or purchase of, a Mortgage Loan or an REO Property
only on the terms and subject to the conditions set forth in this Section 3.18
or as otherwise expressly provided in or contemplated by Sections 2.03(a) and
9.01.

     (b) After a Mortgage Loan becomes a Defaulted Mortgage Loan, the Special
Servicer shall determine the fair value of the Mortgage Loan in accordance with
the Servicing Standard; provided, however, that such determination shall be made
without taking into account any effect the restrictions on the sale of such
Mortgage Loan contained herein may have on the value of such Defaulted Mortgage
Loan; provided, further, that the Special Servicer shall use reasonable efforts
promptly to obtain an Appraisal with respect to the related Mortgage Property
unless it has an Appraisal that is less than 12 months old and has no actual
knowledge of, or notice of, any event which in the Special Servicer's judgment
would materially affect the validity of such Appraisal. The Special Servicer
shall make its fair value determination as soon as reasonably practicable (but
in any event within thirty (30) days) after its receipt of such new Appraisal,
if applicable. The Special Servicer will be permitted, from time to time, to
adjust its fair value determination based upon changed circumstances, new
information and other relevant factors, in each instance in accordance with the
Servicing Standard; provided, however, that the Special Servicer shall update
its fair value determination at least once every 90 days; provided further that
absent the Special Servicer having actual knowledge of a material change in
circumstances affecting the value of the related Mortgaged Property, the Special
Servicer shall not be obligated to update such determination. The Special
Servicer shall notify the Trustee, the Master Servicer, each Rating Agency, the
Majority Subordinate Certificateholder (and, if

                                      157
<PAGE>

applicable, the related Companion Holder) promptly upon its fair value
determination and any adjustment thereto. The Special Servicer shall also
deliver to the Master Servicer and the Majority Subordinate Certificateholder
the most recent Appraisal of the related Mortgaged Property then in the Special
Servicer's possession, together with such other third-party reports and other
information then in the Special Servicer's possession that the Special Servicer
reasonably believes to be relevant to the fair value determination with respect
to such Mortgage Loan (such materials are, collectively, the "Determination
Information"). Notwithstanding the foregoing, the Special Servicer shall not be
required to deliver the Determination Information to the Master Servicer, and
shall instead deliver the Determination Information to the Trustee, if the
Master Servicer will not be determining whether the Option Price represents fair
value for the Defaulted Mortgage Loan, pursuant to this Section 3.18.

     In determining the fair value of any Defaulted Mortgage Loan, the Special
Servicer shall take into account, among other factors, the period and amount of
the delinquency on such Mortgage Loan, the occupancy level and physical
condition of the related Mortgaged Property, the state of the local economy in
the area where the Mortgaged Property is located, and the time and expense
associated with a purchaser's foreclosing on the related Mortgaged Property and
the expected recoveries from pursuing a work-out or foreclosure strategy instead
of selling the Defaulted Mortgage Loan to the Purchase Option holder. In
addition, the Special Servicer shall refer to all other relevant information
obtained by it or otherwise contained in the Mortgage Loan File; provided that
the Special Servicer shall take account of any change in circumstances regarding
the related Mortgaged Property known to the Special Servicer that has occurred
subsequent to, and that would, in the Special Servicer's reasonable judgment,
materially affect the value of the related Mortgaged Property reflected in the
most recent related Appraisal. Furthermore, the Special Servicer shall consider
all available objective third-party information obtained from generally
available sources, as well as information obtained from vendors providing real
estate services to the Special Servicer, concerning the market for distressed
real estate loans and the real estate market for the subject property type in
the area where the related Mortgaged Property is located.

     (c) Subject to the terms set forth in Section 2.03, in the event a Mortgage
Loan becomes a Defaulted Mortgage Loan, each of the Majority Subordinate
Certificateholder and the Special Servicer (each, together with their assignees,
an "Option Holder") shall have an assignable option (a "Purchase Option"),
subject to the right of the related Companion Holder to purchase the related
Pooled Mortgage Loan or the related REO Property as described in Section 3.26(d)
(with respect to the 77 West Wacker Drive Mortgage Loan, subject to Section
3.18(d)), to purchase such Defaulted Mortgage Loan from the Trust Fund at a
price (the "Option Price") equal to (i) the Purchase Price, if the Special
Servicer has not yet determined the fair value of the Defaulted Mortgage Loan,
or (ii) the fair value of the Defaulted Mortgage Loan as determined by the
Special Servicer in the manner described in Section 3.18(b) and in accordance
with the Servicing Standard, if the Special Servicer has made such fair value
determination. The Special Servicer shall, promptly after a Mortgage Loan
becomes a Defaulted Mortgage Loan, deliver to the Majority Subordinate
Certificateholder a notice substantially in the form of Exhibit M-1. Any holder
of a Purchase Option may sell, transfer, assign or otherwise convey its Purchase
Option with respect to any Defaulted Mortgage Loan to any party at any time
after the related Mortgage Loan becomes a Defaulted Mortgage Loan. The
transferor of any Purchase Option shall notify the Trustee and the Master
Servicer of such transfer and such notice shall include (i)

                                      158
<PAGE>

in the case of the Majority Subordinate Certificateholder, an assignment
substantially in the form of Exhibit M-3, or (ii) in the case of the Special
Servicer, an assignment substantially in the form of Exhibit M-2.
Notwithstanding the foregoing, the Majority Subordinate Certificateholder (or
its assignee) shall have the right to exercise its Purchase Option prior to any
exercise of the Purchase Option by the Special Servicer; provided, however, if
the Purchase Option is not exercised by the Majority Subordinate
Certificateholder or any assignee thereof within 60 days of a Mortgage Loan
becoming a Defaulted Mortgage Loan, then the Special Servicer (or its assignee)
shall have the right, but subject to the right of the related Companion Holder
to purchase the related Pooled Mortgage Loan or the related REO Property as
described in Section 3.26(d), to exercise its Purchase Option prior to any
exercise by the Majority Subordinate Certificateholder and the Special Servicer
or its assignee may exercise such Purchase Option at any time during the fifteen
day period immediately following the expiration of such 60-day period. Following
the expiration of such fifteen day period, the Majority Subordinate
Certificateholder (or its assignee) shall again have the right to exercise its
Purchase Option prior to any exercise of the Purchase Option by the Special
Servicer. If not exercised earlier, the Purchase Option with respect to any
Defaulted Mortgage Loan will automatically terminate (i) once the related
Defaulted Mortgage Loan is no longer a Defaulted Mortgage Loan; provided,
however, that if such Mortgage Loan subsequently becomes a Defaulted Mortgage
Loan, the related Purchase Option shall again be exercisable, (ii) upon the
acquisition, by or on behalf of the Trust Fund, of title to the related
Mortgaged Property through foreclosure or deed in lieu of foreclosure or (iii)
the modification or pay-off, in full or at a discount, of such Defaulted
Mortgage Loan in connection with a workout. In addition, the Purchase Option
with respect to a Defaulted Mortgage Loan held by any Person will terminate upon
the exercise of the Purchase Option and consummation of the purchase by any
other holder of a Purchase Option.

     (d) If the 77 West Wacker Drive Mortgage Loan becomes a Defaulted Mortgage
Loan, the Special Servicer shall promptly notify in writing the Servicer and the
Trustee, and the Trustee, following its receipt of such notice, shall promptly
notify the Holders of the Class WW Certificates. Upon receipt of such notice,
the WW Controlling Holder, on behalf of the Holders of the Class WW
Certificates, will have the first option, but not the obligation, to purchase
the 77 West Wacker Drive Mortgage Loan (including the 77 West Wacker Drive
Non-Pooled Portion) from the Trust Fund at a price equal to the Option Price. If
the WW Controlling Holder fails to exercise such option within 30 days after
receipt of such notice, then the 77 West Wacker Drive Mortgage Loan may be sold
in accordance with this Section 3.18.

     If, while the Fairfield Commons Total Loan is being serviced under this
Agreement prior to the Fairfield Commons Pari Passu Companion Loan being
included in the Series 2003-C5 Securitization, the Fairfield Commons Mortgage
Loan becomes a Defaulted Mortgage Loan, the Special Servicer shall deliver to
the holder of the Fairfield Commons Pari Passu Companion Loan copies of all
written and/or electronic information used by the Special Servicer to establish
the fair value of the Fairfield Commons Total Loan, together with, at the
expense of such holder, such other information as such holder may reasonably
request to perform a similar valuation of the Fairfield Commons Pari Passu
Companion Loan.

     (e) The parties hereto acknowledge the purchase options of the holder of
the Fairfield Commons Pari Passu Companion Loan with respect to the Fairfield
Commons Pooled Mortgage Loan provided for in Section 3.26. The purchase price
paid by the holder of the

                                      159
<PAGE>

Fairfield Commons Pari Passu Companion Loan for the Fairfield Commons Total Loan
in accordance with either such purchase option shall be deposited into the
Companion Loan Custodial Account, and the Trustee, upon receipt of written
notice from the Master Servicer to the effect that such deposit and transfer has
been made, shall execute and deliver such instruments of transfer or assignment,
in each case without recourse, as shall be provided to it and are reasonably
necessary to vest ownership of the Fairfield Commons Pooled Mortgage Loan in the
holder of the Fairfield Commons Pari Passu Companion Loan.

     (f) Upon receipt of notice from the Special Servicer indicating that a
Mortgage Loan has become a Defaulted Mortgage Loan, the holder (whether the
original grantee of such option or any subsequent transferee) of the Purchase
Option may, subject to the right of the related Companion Holder to purchase the
related Pooled Mortgage Loan or the related REO Property as described in Section
3.26(d), exercise the Purchase Option by providing the Master Servicer and the
Trustee written notice thereof (the "Purchase Option Notice"), which notice
shall identify the Person that, on its own or through an Affiliate, will acquire
the related Mortgage Loan upon closing and shall specify a cash exercise price
at least equal to the Option Price. The Purchase Option Notice shall be
delivered in the manner specified in Section 11.05. The exercise of any Purchase
Option pursuant to this clause (e) shall be irrevocable; provided, that the
assignor of the Purchase Option shall have no liability to the Trust Fund or any
other party hereto for the failure of its third party assignee to close the sale
of the Defaulted Mortgage Loan after its exercise of the Purchase Option and
upon such failure, the Purchase Option shall revert to the Option Holder as
provided herein as if the Purchase Option had not been exercised, and the
Special Servicer shall pursue against such assignee whatever remedies it may
have against the assignee.

     (g) If the Special Servicer or the Majority Subordinate Certificateholder,
or any of their respective Affiliates, is identified in the Purchase Option
Notice as the Person expected to acquire the related Mortgage Loan, and the
Option Price is based upon the Special Servicer's fair value determination, then
the Master Servicer shall determine whether the Special Servicer's determination
of the Option Price represents fair value for the Defaulted Mortgage Loan, in
the manner set forth in Section 3.18(b). In such event, the Special Servicer
shall promptly deliver to the Master Servicer the Determination Information,
including information regarding any change in circumstance regarding the
Defaulted Mortgage Loan known to the Special Servicer that has occurred
subsequent to, and that would materially affect the value of the related
Mortgaged Property reflected in, the most recent related Appraisal.
Notwithstanding the foregoing, and if the Special Servicer has not already done
so, the Master Servicer may (at its option) designate an Independent Appraiser
or other Independent expert of recognized standing having experience in
evaluating the value of defaulted mortgage loans, selected with reasonable care
by the Master Servicer, to confirm that the Special Servicer's determination of
the Option Price represents fair value for the Defaulted Mortgage Loan (which
opinion shall be based on a review, analysis and evaluation of the Determination
Information, and to the extent such an Independent Appraiser or third party
deems any such Determination Information to be defective, incorrect,
insufficient or unreliable, such Person may base its opinion on such other
information it deems reasonable or appropriate). In that event, the Master
Servicer, absent manifest error, may conclusively rely on the opinion of any
such Person.

                                      160

     The costs of all appraisals, inspection reports and opinions of value
incurred by the Special Servicer or the Master Servicer or any such third party
pursuant to this paragraph shall be advanced by the Master Servicer and shall
constitute, and be reimbursable as, Servicing Advances. In addition, the Master
Servicer shall be entitled to receive out of the Certificate Account a fee in
the amount of $2,500, for the initial confirmation of the Special Servicer's
Option Price determination (but no fee for any subsequent confirmation) that is
made by it with respect to any Specially Designated Defaulted Mortgage Loan, in
accordance with this Section 3.18(f).

     Notwithstanding anything contained in this Section 3.18(f) to the contrary,
if the Special Servicer, the Majority Subordinate Certificateholder or any of
their respective Affiliates, is identified in the Purchase Option Notice as the
Person expected to acquire the related Mortgage Loan, and the Option Price is
based upon the Special Servicer's fair value determination, and the Master
Servicer and the Special Servicer are Affiliates, the Trustee shall determine
whether the Option Price represents fair value for the Defaulted Mortgage Loan,
in the manner set forth in Section 3.18(b) and as soon as reasonably practicable
but in any event within thirty (30) days (except as such period may be extended
as set forth in this paragraph) of its receipt of the Purchase Option Notice and
Determination Information from the Special Servicer. In determining whether the
Option Price represents the fair value of such Defaulted Mortgage Loan, the
Trustee may obtain an opinion as to the fair value of such Defaulted Mortgage
Loans, taking into account the factors set forth in Section 3.18(b), from an
Independent Appraiser or other Independent expert of recognized standing having
experience in evaluating the value of defaulted mortgage loans which opinion
shall be based on a review, analysis and evaluation of the Determination
Information, and to the extent such an Independent Appraiser or third party
deems any such Determination Information to be defective, incorrect,
insufficient or unreliable, such Person may base its opinion on such other
information it deems reasonable or appropriate, and absent manifest error, the
Trustee may conclusively rely on the opinion of any such Person which was chosen
by the Trustee with reasonable care. Notwithstanding the thirty (30) day time
period referenced above in this paragraph, the Trustee will have an additional
fifteen (15) days to make a fair value determination if the Person referenced in
the immediately preceding sentence has determined that the Determination
Information is defective, incorrect, insufficient or unreliable. The reasonable
costs of all appraisals, inspection reports and opinions of value, reasonably
incurred by the Trustee or any such third party pursuant to this paragraph shall
be advanced by the Master Servicer and shall constitute, and be reimbursable as,
Servicing Advances. In connection with the Trustee's determination of fair value
the Special Servicer shall deliver to the Trustee the Determination Information
for the use of the Trustee or any such third party.

     In the event a designated third party determines that the Option Price is
less than the fair value of the Defaulted Mortgage Loan, such party shall
provide its determination, together will all information and reports it relied
upon in making such determination, to the Special Servicer, the Master Servicer
or the Trustee, as the case may be, and the Special Servicer shall then adjust
its fair value determination and, consequently, the Option Price, pursuant to
Section 3.18(b). The Special Servicer shall promptly provide written notice of
any adjustment of the Option Price to the Option Holder whose Purchase Option
has been declared effective pursuant to Section 3.18(e) above. Upon receipt of
such notice, such Option Holder shall have three (3) Business Days to (i) accept
the Option Price as adjusted and proceed in accordance with

                                      161
<PAGE>

Section 3.18(g) below, or (ii) reject the Option Price as adjusted, in which
case such Option Holder shall not be obligated to close the purchase of the
Defaulted Mortgage Loan. Upon notice from such Option Holder, that it rejects
the Option Price as adjusted, the Special Servicer and the Trustee shall provide
the notices described in Section 3.18(h) below and thereafter any Option Holder
may exercise its purchase option in accordance with this Section 3.18, at the
Option Price as adjusted.

     (h) The Option Holder whose Purchase Option is declared effective pursuant
to Section 3.18(e) above shall be required to pay the purchase price specified
in its Purchase Option Notice to the Master Servicer within ten (10) Business
Days of its receipt of the Master Servicer's notice confirming that the exercise
of its Purchase Option is effective. Upon receipt of a Request for Release from
the Master Servicer specifying the date for closing the purchase of the related
Defaulted Mortgage Loan, and the purchase price to be paid therefor, the Trustee
shall deliver at such closing for release to or at the direction of such Option
Holder, the related Mortgage File, and shall execute and deliver such
instruments of transfer or assignment, in each case without recourse, as shall
be provided to it by such Option Holder and are reasonably necessary to vest in
the purchaser or any designee thereof the ownership of such Mortgage Loan. In
connection with any such purchase by any Person other than it, the Special
Servicer shall deliver the related Mortgage File to or at the direction of the
purchaser. In any case, the Master Servicer shall deposit the purchase price
(except that portion of any purchase price constituting Gain-on-Sale Proceeds
which shall be deposited in the Gain-on-Sale Reserve Account) into the
Certificate Account within one (1) Business Day following receipt.

     (i) The Special Servicer shall immediately notify the Trustee and the
Master Servicer upon the holder of the effective Purchase Option's failure to
remit the purchase price specified in its Purchase Option Notice pursuant to
this Section 3.18(h). Thereafter, the Trustee shall notify each Option Holder of
such failure and any Option Holder may then exercise its purchase option in
accordance with this Section 3.18.

     (j) Unless and until the Purchase Option with respect to a Defaulted
Mortgage Loan is exercised, the Special Servicer shall pursue such other
resolution strategies available hereunder with respect to such Defaulted
Mortgage Loan, including, without limitation, workout and foreclosure, as the
Special Servicer may deem appropriate consistent with the Servicing Standard;
provided, however, the Special Servicer will not be permitted to sell the
Defaulted Mortgage Loan other than in connection with the exercise of the
related Purchase Option.

     (k) In the event that title to any REO Property is acquired by the Trust in
respect of any Defaulted Mortgage Loan, the deed or certificate of sale shall be
issued to the Trust, the Trustee or to its nominees. The Special Servicer, after
notice to the Controlling Class Representative, shall use its reasonable best
efforts to sell any REO Property as soon as practicable in accordance with
Section 3.16(a). If the Special Servicer on behalf of the Trustee has not
received an REO Extension or an Opinion of Counsel described in Section 3.16(a)
and the Special Servicer is not able to sell such REO Property within the period
specified above, or if an REO Extension has been granted and the Special
Servicer is unable to sell such REO Property within the extended time period,
the Special Servicer shall, after consultation with the Controlling Class
Representative, before the end of such period or extended period, as the case
may be, auction the REO Property to the highest bidder (which may be the Special
Servicer) in

                                      162
<PAGE>

accordance with the Servicing Standard. The Special Servicer shall give the
Controlling Class Representative, the Master Servicer and the Trustee not less
than five days' prior written notice of its intention to sell any REO Property,
and in respect of such sale, the Special Servicer shall offer such REO Property
in a commercially reasonable manner. Where any Interested Person is among those
bidding with respect to an REO Property, the Special Servicer shall require that
all bids be submitted in writing and be accompanied by a refundable deposit of
cash in an amount equal to 5% of the bid amount. No Interested Person shall be
permitted to purchase the REO Property at a price less than the Purchase Price;
and provided, further that if the Special Servicer intends to bid on any REO
Property, (i) the Special Servicer shall notify the Trustee of such intent, (ii)
the Trustee shall promptly obtain, at the expense of the Trust Fund, an
Appraisal of such REO Property and (iii) the Special Servicer shall not bid less
than the greater of (a) the fair market value set forth in such Appraisal or (b)
the Purchase Price.

     (l) Subject to the REMIC Provisions, the Special Servicer shall act on
behalf of the Trust in negotiating and taking any other action necessary or
appropriate in connection with the sale of any REO Property or the exercise of a
Purchase Option, including the collection of all amounts payable in connection
therewith. Notwithstanding anything to the contrary herein, neither the Trustee,
in its individual capacity, nor any of its Affiliates may bid for or purchase
any REO Property or purchase any Defaulted Mortgage Loan. Any sale of a
Defaulted Mortgage Loan (pursuant to a Purchase Option) or an REO Property shall
be without recourse to, or representation or warranty by, the Trustee, the
Fiscal Agent, the Depositor, the Special Servicer, the Master Servicer, any
Mortgage Loan Seller or the Trust. None of the Special Servicer, the Master
Servicer, the Depositor, the Trustee or the Fiscal Agent shall have any
liability to the Trust or any Certificateholder with respect to the price at
which a Defaulted Mortgage Loan is sold if the sale is consummated in accordance
with the terms of this Agreement.

     (m) Upon exercise of a Purchase Option, the holder of such Purchase Option
shall be required to pay the purchase price specified in its Purchase Option
Notice to the Special Servicer within 10 Business Days of exercising its
Purchase Option. The proceeds of any sale of a Defaulted Mortgage Loan, after
deduction of the expenses of such sale incurred in connection therewith, shall
be deposited by the Special Servicer in the Certificate Account.

     (n) Reserved.

     (o) Notwithstanding anything herein to the contrary, the Special Servicer
shall not take or refrain from taking any action pursuant to instructions from
the Controlling Class Representative that would cause it to violate applicable
law or any term or provision of this Agreement, including the REMIC Provisions
and the Servicing Standard.

     (p) The amount paid for a Defaulted Mortgage Loan or related REO Property
purchased under this Agreement shall be deposited into the Certificate Account,
or if applicable, applied in accordance with the related Intercreditor
Agreement. Upon receipt of an Officers' Certificate from the Master Servicer to
the effect that such deposit has been made, the Trustee shall execute and
deliver such instruments of transfer or assignment, in each case without
recourse, as shall be provided to it and are reasonably necessary to vest in the
purchaser of such Defaulted Mortgage Loan or related REO Property ownership of
the Defaulted Mortgage Loan or REO Property. The Custodian, upon receipt of a
Request for Release, shall release or cause to

                                      163
<PAGE>

be released to the Master Servicer or Special Servicer the related Mortgage
File. In connection with any such purchase, the Special Servicer shall deliver
the related Servicing File to the purchaser of a Defaulted Mortgage Loan or
related REO Property.

     SECTION 3.19   Additional Obligations of Master Servicer.

     (a) The Master Servicer shall deposit in the Certificate Account on each
P&I Advance Date, without any right of reimbursement therefor with respect to
each Mortgage Loan that was subject to a Principal Prepayment during the most
recently ended Collection Period (other than Principal Prepayments made out of
Insurance Proceeds, condemnation proceeds or Liquidation Proceeds) creating a
Prepayment Interest Shortfall, an amount equal to the lesser of (i) the amount
of the related Prepayment Interest Shortfall and (ii) the sum of (A) the Master
Servicing Fee (excluding any primary servicing fees) received by the Master
Servicer during such Collection Period on such Mortgage Loan, (B) investment
income earned by the Master Servicer on the related Principal Prepayment during
the most recently ended Collection Period and (C) the total amount of Prepayment
Interest Excesses that were collected during the related Collection Period,
provided, however, that if a Prepayment Interest Shortfall occurs as a result of
the Master Servicer's allowing the related Mortgagor to deviate from the terms
of the related Mortgage Loan Documents regarding principal prepayments (other
than (a) subsequent to a material default under the related Mortgage Loan
Documents, (b) pursuant to applicable law or a court order, or (c) at the
request or with the consent of the Controlling Class Representative) then, for
purposes of determining the payment that the Master Servicer is required to make
to cover that Prepayment Interest Shortfall, the reference to "Master Servicing
Fee" in clause (A) above shall be construed to include a portion of the primary
servicing fees payable to Master Servicer but not any of those payable to a
third-party primary servicer.

     If any Prepayment Interest Shortfalls are incurred with respect to any
Mortgage Loans by reason of involuntary prepayments being made with Insurance
Proceeds and/or condemnation proceeds during any Collection Period, the Master
Servicer shall make a non-reimbursable payment with respect to the related
Distribution Date in an amount equal to the lesser of (A) the total amount of
those Prepayment Interest Shortfalls that were incurred by reason of involuntary
prepayments being made with Insurance Proceeds and/or condemnation proceeds and
(B) any investment income earned by the Master Servicer on the related Principal
Prepayment. The Master Servicer's obligation to make any particular deposit in
respect of any Collection Period as set forth in this Section 3.19(a) shall not
be cumulative as to any other Collection Period.

     (b) The Master Servicer shall, as to each Mortgage Loan which is secured by
the interest of the related Mortgagor under a Ground Lease, promptly (and in any
event within 60 days of the Closing Date) notify the related ground lessor in
writing of the transfer of such Mortgage Loan to the Trust Fund pursuant to this
Agreement and inform such ground lessor that any notices of default under the
related Ground Lease should thereafter be forwarded to the Master Servicer. The
costs and expenses of any modifications to Ground Leases shall be paid by the
related Mortgagor.

                                      164
<PAGE>

     (c) The Master Servicer shall provide to each Companion Holder any reports
or notices required to be delivered to such Companion Holder pursuant to the
related Intercreditor Agreement, if any.

     (d) The Master Servicer shall deliver to each Mortgage Loan Seller upon
request, without charge, no more than twice per calendar year a current list of
the Mortgagors relating to the Mortgage Loans where such Mortgage Loan Seller is
identified on the Mortgage Loan Schedule as the related Mortgage Loan Seller and
their respective billing addresses and telephone numbers; provided, however, the
Master Servicer shall be under no obligation to provide any such information not
in its possession.

     SECTION 3.20   Modifications, Waivers, Amendments and Consents.

     (a) The Master Servicer (with respect to any performing Mortgage Loan) and
the Special Servicer (with respect to any Specially Serviced Mortgage Loan) each
may (consistent with the Servicing Standard) agree to any modification, waiver
or amendment of any term of, extend the maturity of, defer or forgive interest
(including Penalty Interest and Additional Interest) on and principal of, defer
or forgive late payment charges, Prepayment Premiums and Yield Maintenance
Charges on, permit the release, addition or substitution of collateral securing,
and/or permit the release, addition or substitution of the Mortgagor on or any
guarantor of, any Mortgage Loan, and/or provide consents with respect to any
leasing activity at a Mortgaged Property securing any Mortgage Loan without the
consent of the Trustee or any Certificateholder; provided, that the Master
Servicers' and the Special Servicers' respective rights to do so shall be
subject to Sections 3.08 and 6.11 (and, in the case of any Loan Pair, subject to
the terms of the related Intercreditor Agreement); and provided further, that
other than as provided in Sections 3.02(a) (relating to waivers of Penalty
Interest and late payment charges), 3.08, 3.20(d) and 3.20(f), the Master
Servicer shall not agree to any modification, waiver, forbearance or amendment
of any term of, or take any of the other acts referenced in this Section 3.20(a)
with respect to, any Mortgage Loan, unless the Master Servicer has obtained the
consent of the Special Servicer (it being understood and agreed that (A) the
Master Servicer will promptly provide the Special Servicer with notice of any
Mortgagor request for such modification, waiver, forbearance or amendment, the
Master Servicer's recommendations and analysis, and all information reasonably
available to the Master Servicer that the Special Servicer may reasonably
request in order to withhold or grant any such consent, (B) the Special Servicer
shall decide whether to withhold or grant such consent in accordance with the
Servicing Standard and (C) if any such consent has not been expressly denied
within 10 Business Days (or, in the case of consents relating to leasing
activities at Mortgaged Properties, within 3 Business Days) after the Special
Servicer's receipt from the Master Servicer of the Master Servicer's
recommendations and analysis and all information reasonably requested thereby
and reasonably available to the Master Servicer in order to make an informed
decision (or, if the Special Servicer did not request any information, within 10
Business Days or three Business Days, as the case may be, after such notice),
such consent shall be deemed to have been granted).

     (b) All modifications, waivers or amendments of any Mortgage Loan shall be
in writing and shall be considered and effected in accordance with the Servicing
Standard; provided however, that neither the Master Servicer nor the Special
Servicer, as applicable, shall make or permit or consent to, as applicable, any
modification, waiver or amendment of any term of any

                                      165
<PAGE>

Mortgage Loan not otherwise permitted by this Section 3.20 that would constitute
a "significant modification" of such Mortgage Loan within the meaning of
Treasury Regulations Section 1.860G-2(b). The Master Servicer or Special
Servicer shall determine and may conclusively rely on an Opinion of Counsel
(which Opinion of Counsel shall be an expense of the Trust Fund to the extent
not paid by the related Mortgagor) to the effect that such modification, waiver
or amendment would not (1) effect an exchange or reissuance of the Mortgage Loan
under Treasury Regulations Section 1.860G-2(b) of the Code, (2) cause 77 West
Wacker Drive Loan REMIC, REMIC I or REMIC II to fail to qualify as a REMIC under
the Code or result in the imposition of any tax on "prohibited transactions" or
"contributions" after the Startup Day under the REMIC Provisions, or (3)
adversely affect the status of the Grantor Trust under the Code.

     (c) In addition to the provisions in Section 3.20(d), Section 3.20(e) and
the last two sentences of Section 3.02(a), the Special Servicer, on behalf of
the Trust Fund, may agree or consent to (or permit the Master Servicer to agree
or consent to) any modification, waiver or amendment of any term of any Mortgage
Loan that would:

          (i) affect the amount or timing of any related payment of principal,
     interest or other amount (including Prepayment Premiums or Yield
     Maintenance Charges, but excluding Penalty Interest and amounts payable as
     additional servicing compensation) payable thereunder; or

          (ii) affect the obligation of the related Mortgagor to pay a
     Prepayment Premium or Yield Maintenance Charge or permit a Principal
     Prepayment during any period in which the related Mortgage Note prohibits
     Principal Prepayments; or

          (iii) in the judgment of the Special Servicer, materially impair the
     security for such Mortgage Loan or reduce the likelihood of timely payment
     of amounts due thereon,

     provided, that a material default on the Mortgage Loan has occurred or, in
the Special Servicer's judgment, a material default on the Mortgage Loan is
reasonably foreseeable, and the modification, waiver, amendment or other action
is reasonably likely to produce a greater recovery to the Certificateholders, as
a collective whole (or with respect to any Loan Pair, the Certificateholders and
the Companion Holder, as a collective whole), on a present value basis, than
would liquidation.

     In addition, subject to the third paragraph of this Section 3.20(c), the
Special Servicer may (or may permit the Master Servicer to) extend the date on
which any Balloon Payment is scheduled to be due in respect of a Specially
Serviced Mortgage Loan if the conditions set forth in the proviso to the prior
paragraph are satisfied and the Special Servicer has obtained an appraisal in
accordance with the standards of the Appraisal Institute of the related
Mortgaged Property, performed by an Independent Appraiser, in connection with
such extension, which appraisal supports the determination of the Special
Servicer contemplated by clause (B) of the proviso to the immediately preceding
paragraph.

     In no event will the Master Servicer or Special Servicer (i) extend the
maturity date of a Mortgage Loan beyond a date that is two years prior to the
Rated Final Distribution

                                      166
<PAGE>

Date and (ii) if the Mortgage Loan is secured by a Ground Lease (and not by the
corresponding fee simple interest), extend the maturity date of such Mortgage
Loan beyond a date which is less than 20 years prior to the expiration of the
term of such Ground Lease including any unilateral options to extend such term.

     The determination of the Special Servicer contemplated by clause (B) of the
proviso to the first paragraph of this Section 3.20(c) shall be evidenced by an
Officer's Certificate to such effect delivered to the Trustee and the Master
Servicer and describing in reasonable detail the basis for the Special
Servicer's determination. The Special Servicer shall append to such Officer's
Certificate any information including but not limited to income and expense
statements, rent rolls, property inspection reports and appraisals that support
such determination.

     (d) Except as expressly contemplated by the related Mortgage Loan
Documents, the Special Servicer shall not release (and, in the case of a
performing Mortgage Loan, the Special Servicer shall not consent to the Master
Servicer's releasing, which consent shall be deemed given if not denied in
writing within 10 Business Days), any real property collateral securing an
outstanding Mortgage Loan, except as provided in Section 3.09 or 3.20(e), or
except in connection with a permitted defeasance, or except where a Mortgage
Loan (or, in the case of a Crossed Group, where such entire Crossed Group) is
satisfied, or except in the case of a release of real property collateral
provided (A) the Rating Agencies have been notified in writing, (B) either (1)
such release will not, in the reasonable judgment of the Special Servicer,
materially and adversely affect the net operating income being generated by or
the then-current use of the related Mortgaged Property, or (2) there is a
corresponding principal pay down of such Mortgage Loan in an amount at least
equal to the appraised value of the collateral to be released (or substitute
real property collateral with an appraised value at least equal to that of the
collateral to be released, is delivered), (C) the release does not materially
adversely affect the adequacy of the remaining Mortgaged Property (together with
any substitute real property collateral), in the reasonable judgment of the
Special Servicer, as security for the Mortgage Loan and (D) if the real property
collateral to be released has an appraised value in excess of $1,500,000, such
release would not, in and of itself, result in an Adverse Rating Event with
respect to any Class of rated Certificates (as confirmed in writing to the
Trustee by each Rating Agency).

     (e) Notwithstanding anything in this Section 3.20 or in Section 3.08 or
Section 6.11 to the contrary, the Master Servicer shall not be required to seek
the consent of, or provide prior notice to, the Special Servicer or any
Certificateholder (including the Controlling Class Representative) or obtain any
confirmation of the Certificate ratings from the Rating Agencies in order to
approve the following modifications, waivers or amendments of the Mortgage Loans
(but, in the case of the actions described in clauses (iii) and (iv) of this
sentence, shall notify the Controlling Class Representative thereof): (i)
waivers of non-material covenant defaults (other than financial covenants),
including late financial statements; (ii) waivers of Penalty Interest and late
payment charges, to the extent allowed under Section 3.02; (iii) releases of
parcels of a Mortgaged Property (provided that any such releases (A) are
releases as to which the related Mortgage Loan Documents expressly require the
Mortgagee thereunder to make such releases upon the satisfaction of certain
conditions and such releases shall be made as required by the Mortgage Loan
Documents, or (B) are related to any pending or threatened condemnation action);
(iv) grants of easements, rights-of-way or other similar agreements (and related
consents

                                      167
<PAGE>

to the subordination of the Mortgage Loan thereto) that do not materially affect
the use or value of a Mortgaged Property or the Mortgagor's ability to make any
payments with respect to the related Mortgage Loan; (v) with respect to a
Mortgage Loan (A) with an unpaid principal balance of greater than $3,000,000,
approval of routine leasing activities that affect less than the lesser of
30,000 square feet or 30% of the net rentable area of the related Mortgaged
Property, or (B) with an unpaid principal balance of $3,000,000 or less,
approval of any routine leasing activity; (vi) approval of annual budgets to
operate the Mortgaged Property; (vii) temporary waivers of any requirements in
the related Mortgage Loan Documents with respect to insurance deductible amounts
or claims-paying ability ratings of insurance providers; and (viii) consenting
to changing the property manager with respect to any Mortgage Loan with an
unpaid principal balance of less than $10,000,000; provided, that any such
modification, waiver or amendment, or agreeing to any such modification, waiver
or amendment, (w) would not in any way affect a payment term of the Certificates
or any Companion Loan, (x) would not constitute a "significant modification" of
such Mortgage Loan pursuant to Treasury Regulations Section 1.860G-2(b) and
would not otherwise constitute an Adverse REMIC Event with respect to any REMIC
or an Adverse Grantor Trust Event with respect to the Grantor Trust, (y) would
be consistent with the Servicing Standard, and (z) shall not violate the terms,
provisions or limitations of this Agreement or any other document contemplated
hereby.

     (f) Any payment of interest (other than Mortgage Deferred Interest) that is
deferred pursuant to any modification, waiver or amendment permitted hereunder,
shall not, for purposes hereof, including, without limitation, calculating
monthly distributions to Certificateholders, be added to the unpaid principal
balance or Stated Principal Balance of the related Mortgage Loan,
notwithstanding that the terms of such modification, waiver or amendment so
permit. The foregoing shall in no way limit the Special Servicer's ability to
charge and collect from the Mortgagor costs otherwise collectible under the
terms of the related Mortgage Note and this Agreement together with interest
thereon.

     (g) The Special Servicer or, the Master Servicer may, as a condition to
granting any request by a Mortgagor for consent, modification, waiver or
indulgence or any other matter or thing, the granting of which is within its
discretion pursuant to the terms of the instruments evidencing or securing the
related Mortgage Loan and is permitted by the terms of this Agreement, require
that such Mortgagor pay to it (i) as additional servicing compensation, a
reasonable or customary fee for the additional services performed in connection
with such request, provided such fee would not itself be a "significant
modification" pursuant to Treasury Regulations Section 1.1001-3(e)(2) and (ii)
any related costs and expenses incurred by it. In no event shall the Special
Servicer be entitled to payment for such fees or expenses unless such payment is
collected from the related Mortgagor.

     (h) The Master Servicer and Special Servicer shall notify each other, the
Trustee and the Controlling Class Representative and with respect to each Loan
Pair, the related Companion Holder, in writing, of any modification, waiver or
amendment of any term of any Mortgage Loan (including fees charged the
Mortgagor) and the date thereof, and shall deliver to the Custodian for deposit
in the related Mortgage File, (in the case of the Special Servicer, with a copy
to the Master Servicer), an original counterpart of the agreement relating to
such modification, waiver or amendment, promptly (and in any event within ten
Business Days) following the execution thereof. Copies of each agreement whereby
any such modification,

                                      168
<PAGE>

waiver or amendment of any term of any Mortgage Loan is effected shall be made
available for review upon prior request during normal business hours at the
offices of the Master Servicer pursuant to Section 3.15(a) hereof.

     (i) With respect to each Mortgage Loan that provides for defeasance, the
Master Servicer shall, to the extent permitted by the terms of such Mortgage
Loan, require the related Mortgagor (i) to provide replacement collateral
consisting of U.S. government securities within the meaning of Treasury
Regulations Section 1.860G-2(a)(8)(i) in an amount sufficient to make all
scheduled payments under the Mortgage Loan (or defeased portion thereof) when
due (and assuming, in the case of an ARD Loan, to the extent consistent with the
related Mortgage Loan Documents, that such Mortgage Loan matures on its
Anticipated Repayment Date), (ii) to deliver a certificate from an independent
certified public accounting firm certifying that the replacement collateral is
sufficient to make such payments, (iii) at the option of the Master Servicer, to
designate a single purpose entity (which may be a subsidiary of the Master
Servicer established for the purpose of assuming all defeased Mortgage Loans) to
assume the Mortgage Loan (or defeased portion thereof) and own the defeasance
collateral, (iv) to implement such defeasance only after the second anniversary
of the Closing Date, (v) to provide an Opinion of Counsel that the Trustee has a
perfected, first priority security interest in the new collateral (subject to
bankruptcy, insolvency and similar standard exceptions), and (vi) in the case of
a partial defeasance of the Mortgage Loan, to defease a principal amount equal
to at least 125% of the allocated loan amount for the Mortgaged Property or
Properties to be released. If the subject Mortgage Loan has a Cut-off Date
Principal Balance of less than $20,000,000 and an outstanding principal balance
less than 2% of the then aggregate Stated Principal Balance of the Mortgage Pool
and is not one of the 10 largest Mortgage Loans then in the Trust Fund, and if
either the terms of the subject Mortgage Loan permit the Master Servicer to
impose the foregoing requirements or the Master Servicer satisfies such
requirements on its own, then confirmation that such defeasance will not result
in an Adverse Rating Event is not required so long as the Master Servicer
delivers to S&P a certification in the form attached hereto as Exhibit K. In
such case, the Master Servicer shall provide the Rating Agencies and the
Controlling Class Representative with notice that the foregoing requirements
have been met with respect to the subject Mortgage Loan. However, if the subject
Mortgage Loan has a Cut-off Date Principal Balance greater than or equal to
$20,000,000 or an outstanding principal balance greater than or equal to 2% of
the aggregate Stated Principal Balance of the Mortgage Pool or is one of the 10
largest Mortgage Loans then in the Trust Fund, or if the terms of the subject
Mortgage Loan do not permit the Master Servicer to impose such requirements and
the Master Servicer does not satisfy such requirements on its own, then the
Master Servicer shall so notify the Rating Agencies and the Controlling Class
Representative and, so long as such a requirement would not violate applicable
law or the Servicing Standard, obtain a confirmation that such defeasance will
not result in an Adverse Rating Event. Subject to the related Mortgage Loan
Documents and applicable law, the Master Servicer shall not execute a defeasance
unless (i) the subject Mortgage Loan requires the Mortgagor to pay all Rating
Agency fees associated with defeasance (if Rating Agency confirmation of
no-downgrade is a specific condition precedent thereto) and all expenses
associated with defeasance or other arrangements for payment of such costs are
made at no expense to the Trust Fund or the Master Servicer (provided however,
that in no event shall such proposed "other arrangements" result in any
liability to the Trust Fund including any indemnification of the Master Servicer
or the Special Servicer which may result in legal expenses to the Trust Fund),
and (ii) the Mortgagor is required to provide all Opinions of

                                      169
<PAGE>

Counsel, including Opinions of Counsel that the defeasance will not cause an
Adverse REMIC Event or an Adverse Grantor Trust Event and that the Mortgage Loan
Documents are fully enforceable in accordance with their terms (subject to
bankruptcy, insolvency and similar standard exceptions), and any applicable
rating confirmations.

     Subsequent to the second anniversary of the Closing Date, to the extent
that the Master Servicer can, in accordance with the related Mortgage Loan
Documents, require defeasance of any Mortgage Loan in lieu of accepting a
prepayment of principal thereunder, including a prepayment of principal
accompanied by a Prepayment Premium or Yield Maintenance Charge, the Master
Servicer shall, to the extent it is consistent with the Servicing Standard,
require such defeasance, provided that the conditions set forth in clauses (i)
through (vi) of the first sentence of the immediately preceding paragraph have
been satisfied. Notwithstanding the foregoing, if at any time, a court with
jurisdiction in the matter shall hold that the related Mortgagor may obtain a
release of the subject Mortgaged Property but is not obligated to deliver the
full amount of the defeasance collateral contemplated by the related Mortgage
Loan Documents (or cash sufficient to purchase such defeasance collateral), then
the Master Servicer shall (i) if consistent with the related Mortgage Loan
Documents, refuse to allow the defeasance of the Mortgage Loan or (ii) if the
Master Servicer cannot so refuse and if the related Mortgagor has delivered cash
to purchase defeasance collateral, the Master Servicer shall either (A) to the
extent of the cash delivered by the Mortgagor, purchase defeasance collateral or
(B) prepay the Mortgage Loan, in either case, in accordance with the Servicing
Standard.

     For purposes of this paragraph, a "single purpose entity" shall mean a
Person, other than an individual, whose organization documents provide as
follows: it is formed solely for the purpose of owning and operating a single
property, assuming a Mortgage Loan and owning and pledging the Defeasance
Collateral; it may not engage in any business unrelated to such property and the
financing thereof; it does not have and may not own any assets other than those
related to its interest in the property or the financing thereof and may not
incur any indebtedness other than as permitted by the related Mortgage; it shall
maintain its own books, records and accounts, in each case which are separate
and apart from the books, records and accounts of any other person; it shall
hold regular meetings, as appropriate, to conduct its business, and shall
observe all entity-level formalities and record keeping; it shall conduct
business in its own name and use separate stationery, invoices and checks; it
may not guarantee or assume the debts or obligations of any other person; it
shall not commingle its assets or funds with those of any other person; it shall
pay its obligations and expenses from its own funds and allocate and charge
reasonably and fairly any common employees or overhead shared with affiliates;
it shall prepare separate tax returns and financial statements or, if part of a
consolidated group, shall be shown as a separate member of such group; it shall
transact business with affiliates on an arm's length basis pursuant to written
agreements; and it shall hold itself out as being a legal entity, separate and
apart from any other person. The single purpose entity organizational documents
shall provide that any dissolution and winding up or insolvency filing for such
entity requires the unanimous consent of all partners or members, as applicable,
and that such documents may not be amended with respect to the single purpose
entity requirements during the term of the Mortgage Loan.

     (j) To the extent that either the Master Servicer or Special Servicer
waives any Penalty Interest or late charge in respect of any Mortgage Loan,
whether pursuant to Section

                                      170
<PAGE>

3.02(a) or this Section 3.20, the respective amounts of additional servicing
compensation payable to the Master Servicer and the Special Servicer under
Section 3.11 out of such Penalty Interest or late payment charges shall be
reduced proportionately, based upon the respective amounts that had been payable
thereto out of such Penalty Interest or late payment charges immediately prior
to such waiver.

     (k) Notwithstanding anything to the contrary in this Agreement, neither the
Master Servicer nor the Special Servicer, as applicable, shall take the
following action unless it has received prior written confirmation (the cost of
which shall be paid by the related Mortgagor, if so allowed by the terms of the
related loan documents, and if not so allowed, paid as an Additional Trust Fund
Expense) from the Rating Agencies that such action will not result in a
qualification, downgrade or withdrawal of any of the ratings assigned by such
Rating Agency to the Certificates: with respect to any Mortgaged Property that
secures a Mortgage Loan with an unpaid principal balance that is at least equal
to five percent (5%) of the then aggregate principal balance of all Mortgage
Loans or $20,000,000, the giving of any consent, approval or direction regarding
the termination of the related property manager or the designation of any
replacement property manager (except that prior written confirmation from Fitch
shall not be required unless the Mortgage Loan (A) is one of the ten largest
Mortgage Loans in the Mortgage Pool or (B) when combined with any other Mortgage
Loans made to Mortgagors that are affiliated to the related Mortgagor,
constitutes one of the ten largest Mortgagor concentrations in the Mortgage Pool
based on the then-current outstanding principal balance of all of the Mortgage
Loans).

     (l) Reserved.

     (m) Notwithstanding anything in this Section 3.20 to the contrary:

          (i) the limitations, conditions and restrictions set forth in this
     Section 3.20 shall not apply to any act or event (including, without
     limitation, a release of collateral) in respect of any Mortgage Loan that
     is required under the Mortgage Loan Documents or that either occurs
     automatically or results from the exercise of a unilateral option by the
     related Mortgagor within the meaning of Treasury Regulations Section
     1.1001-3(c)(2)(iii), in any event under the terms of such Mortgage Loan in
     effect on the Closing Date (or, in the case of a Qualified Substitute
     Mortgage Loan, on the related date of substitution);

          (ii) neither the Master Servicer nor the Special Servicer shall be
     required to oppose the confirmation of a plan in any bankruptcy or similar
     proceeding involving a Mortgagor if, in its reasonable judgment, such
     opposition would not ultimately prevent the confirmation of such plan or
     one substantially similar; and

          (iii) neither the Master Servicer nor the Special Servicer shall be
     required to obtain any confirmation of the Certificate ratings from the
     Rating Agencies in order to grant easements, rights-of-way or other similar
     agreements (and related consents to subordinate the Mortgage Loan thereto)
     that do not materially affect the use or value of a Mortgaged Property or
     the Mortgagor's ability to make any payments with respect to the related
     Mortgage Loan.

                                      171
<PAGE>

     (n) Neither the Special Servicer nor the Master Servicer shall have any
liability to the Trust, the Certificateholders, any Companion Holder or any
other Person if its analysis and determination that the modification, waiver,
amendment or other action contemplated by this Section 3.20 is reasonably likely
to produce a greater recovery to Certificateholders (and, if applicable,
Companion Holders) on a present value basis than would liquidation should prove
to be wrong or incorrect, so long as the analysis and determination were made on
a reasonable basis by the Special Servicer and/or the Master Servicer, and
consistent with the Servicing Standard.

     (o) Any modification, waiver or amendment of a monetary term of the
Fairfield Commons Total Loan shall be structured so as to preserve the equal
priority of the Fairfield Commons Pooled Mortgage Loan and the Fairfield Commons
Pari Passu Companion Mortgage Loan. Notwithstanding anything herein to the
contrary, pursuant to the Fairfield Commons Intercreditor Agreement, for so long
as the Fairfield Commons Pari Passu Companion Loan is included in the Series
2003-C5 Securitization, any modifications, consents, waivers, amendments or
other actions contemplated by Section 3.08 or this Section 3.20 shall be
processed and administered by the Series 2003-C5 Master Servicer, and the Series
2003-C5 Special Servicer, subject to the Fairfield Commons Intercreditor
Agreement and the Series 2003-C5 Pooling and Servicing Agreement.

     SECTION 3.21   Transfer of Servicing Between Master Servicer and Special
Servicer; Record Keeping.

     (a) Upon determining that a Servicing Transfer Event has occurred with
respect to any Mortgage Loan, the Master Servicer shall promptly notify the
Trustee, the Special Servicer and the Controlling Class Representative (and with
respect to the 77 West Wacker Drive Mortgage Loan, the WW Controlling Holder)
(and with respect to any Loan Pair, the related Companion Holder) and if the
Master Servicer is not also the Special Servicer, the Master Servicer shall
promptly deliver or cause to be delivered a copy of the related Servicing File,
to the Special Servicer and shall use reasonable efforts to provide the Special
Servicer with all information, documents (or copies thereof) and records
(including records stored electronically on computer tapes, magnetic discs and
the like) relating to the Mortgage Loan and, if applicable, the related
Companion Loan, either in the Master Servicer's or any of its directors',
officers', employees', affiliates' or agents' possession or control or otherwise
available to the Master Servicer without undue burden or expense, and reasonably
requested by the Special Servicer to enable it to assume its functions hereunder
with respect thereto. The Master Servicer shall use reasonable efforts to comply
with the preceding sentence within five Business Days of the occurrence of each
related Servicing Transfer Event; provided, however, if the information,
documents and records requested by the Special Servicer are not contained in the
Servicing File, the Master Servicer shall have such period of time as reasonably
necessary to make such delivery. After the occurrence of a Servicing Transfer
Event, the Special Servicer shall collect payments on such Mortgage Loan and
make remittances to the Master Servicer in accordance with Section 3.04.

     Upon determining that a Specially Serviced Mortgage Loan has become a
Corrected Mortgage Loan and if the Master Servicer is not also the Special
Servicer, the Special Servicer shall immediately give notice thereof to the
Master Servicer and the Controlling Class Representative (and with respect to
the 77 West Wacker Drive Mortgage Loan, the WW

                                      172
<PAGE>

Controlling Holder), (and with respect to any Loan Pair, any related Companion
Holder) and shall return the related Servicing File and all other information,
documents and records that were not part of the Servicing File when it was
delivered to the Special Servicer within five Business Days of the occurrence,
to the Master Servicer (or such other Person as may be directed by the Master
Servicer) and upon giving such notice, and returning such Servicing File, to the
Master Servicer (or such other Person as may be directed by the Master
Servicer), the Special Servicer's obligation to service such Mortgage Loan and,
if applicable, the related Companion Loan, and the Special Servicer's right to
receive the Special Servicing Fee with respect to such Mortgage Loan and, if
applicable, the related Companion Loan, shall terminate, and the obligations of
the Master Servicer to service and administer such Mortgage Loan and, if
applicable, the related Companion Loan, shall resume.

     (b) In servicing any Specially Serviced Mortgage Loans, the Special
Servicer shall provide to the Custodian originals of documents included within
the definition of "Mortgage File" for inclusion in the related Mortgage File
(with a copy of each such original to the Master Servicer), and copies of any
additional related Mortgage Loan information, including correspondence with the
related Mortgagor.

     (c) Reserved.

     (d) No later than 45 days after a Mortgage Loan becomes a Specially
Serviced Mortgage Loan, the Special Servicer shall deliver to each Rating
Agency, the Trustee, the Master Servicer and the Controlling Class
Representative (and in the case of the 77 West Wacker Drive Mortgage Loan, the
WW Controlling Holder) (and with respect to any Loan Pair, any related Companion
Holder) a report (the "Asset Status Report") with respect to such Loan and the
related Mortgaged Property. Such Asset Status Report shall set forth the
following information to the extent reasonably determinable:

          (i) summary of the status of such Specially Serviced Mortgage Loan and
     negotiations with the related Mortgagor;

          (ii) a discussion of the legal and environmental considerations
     reasonably known to the Special Servicer, consistent with the Servicing
     Standard, that are applicable to the exercise of remedies as aforesaid and
     to the enforcement of any related guaranties or other collateral for the
     related Specially Serviced Mortgage Loan and whether outside legal counsel
     has been retained;

          (iii) the most current rent roll and income or operating statement
     available for the related Mortgaged Property;

          (iv) the Appraised Value of the Mortgaged Property together with the
     assumptions used in the calculation thereof;

          (v) summary of the Special Servicer's recommended action with respect
     to such Specially Serviced Mortgage Loan; and

          (vi) such other information as the Special Servicer deems relevant in
     light of the Servicing Standard.

                                      173
<PAGE>

     If, subject to Section 6.11 of this Agreement, within ten (10) Business
Days of receiving an Asset Status Report which relates to a recommended action
for which the Controlling Class Representative (or in the case of the 77 West
Wacker Drive Mortgage Loan, the WW Controlling Holder) is entitled to object
under Section 6.11, the Controlling Class Representative (or in the case of the
77 West Wacker Drive Mortgage Loan, the WW Controlling Holder) does not
disapprove such Asset Status Report in writing, the Special Servicer shall
implement the recommended action as outlined in such Asset Status Report;
provided, however, that the Special Servicer may not take any action that is
contrary to applicable law, the Servicing Standard, or the terms of the
applicable Mortgage Loan Documents. If, subject to Section 6.11 of this
Agreement, the Controlling Class Representative (or in the case of the 77 West
Wacker Drive Mortgage Loan, the WW Controlling Holder) disapproves such Asset
Status Report, the Special Servicer will revise such Asset Status Report and
deliver to the Controlling Class Representative, (and in the case of the 77 West
Wacker Drive Mortgage Loan, the WW Controlling Holder) the Rating Agencies, the
Trustee and the Master Servicer a new Asset Status Report as soon as
practicable, but in no event later than 30 days after such disapproval.

     To the extent any recommended action constitutes a Specially Designated
Servicing Action with respect to the Fairfield Commons Total Loan and the
Fairfield Commons Pari Passu Companion Loan is not included in the Series
2003-C5 Securitization, the Special Servicer shall consult with the holder of
the Fairfield Commons Pari Passu Companion Loan to the extent required by the
Fairfield Commons Intercreditor Agreement.

     The Special Servicer shall revise such Asset Status Report as described
above in this Section 3.21(d) until the Controlling Class Representative (and in
the case of the 77 West Wacker Drive Mortgage Loan, the WW Controlling Holder),
shall fail to disapprove such revised Asset Status Report in writing within ten
(10) Business Days of receiving such revised Asset Status Report or until the
Special Servicer makes one of the determinations described below. The Special
Servicer may, from time to time, modify any Asset Status Report it has
previously delivered and implement such report, provided such report shall have
been prepared, reviewed and not rejected pursuant to the terms of this Section.
Notwithstanding the foregoing, the Special Servicer (i) may, following the
occurrence of an extraordinary event with respect to the related Mortgaged
Property, take any action set forth in such Asset Status Report (and consistent
with the terms hereof) before the expiration of a ten (10) Business Day period
if the Special Servicer has reasonably determined that failure to take such
action would materially and adversely affect the interests of the
Certificateholders and it has made a reasonable effort to contact the
Controlling Class Representative (and in the case of the 77 West Wacker Drive
Mortgage Loan, the WW Controlling Holder), and (ii) in any case, shall determine
whether such affirmative disapproval is not in the best interest of all the
Certificateholders pursuant to the Servicing Standard.

     Upon making such determination in clause (ii) of the immediately preceding
paragraph, the Special Servicer shall notify the Trustee of such rejection and
deliver to the Trustee a proposed notice to Certificateholders which shall
include a copy of the Asset Status Report, and the Trustee shall send such
notice to all Certificateholders. If the majority of such Certificateholders, as
determined by Voting Rights, fail, within 5 days of the Trustee's sending such
notice, to reject such Asset Status Report, the Special Servicer shall implement
the same. If the Asset Status Report is rejected by a majority of the
Certificateholders, (other than for a

                                      174
<PAGE>

reason which violates the Servicing Standard, which shall control), the Special
Servicer shall revise such Asset Status Report as described above in this
Section 3.21(d) and provide a copy of such revised report to the Master
Servicer. The Trustee shall be entitled to reimbursement from the Trust Fund for
the reasonable expenses of providing such notices. Notwithstanding the
foregoing, in the event the Controlling Class Representative (and in the case of
the 77 West Wacker Drive Mortgage Loan, the WW Controlling Holder) and the
Special Servicer have been unable to agree upon an Asset Status Report with
respect to a Specially Serviced Mortgage Loan within 90 days of the Controlling
Class Representative's (and in the case of the 77 West Wacker Drive Mortgage
Loan, the WW Controlling Holder's) receipt of the initial Asset Status Report,
the Special Servicer, subject to the rights of the related Companion Holder
pursuant to the related Intercreditor Agreement, if applicable, shall implement
the actions described in the most recent Asset Status Report submitted to the
Controlling Class Representative (and in the case of the 77 West Wacker Drive
Mortgage Loan, the WW Controlling Holder) by the Special Servicer.

     The Special Servicer shall have the authority to meet with the Mortgagor
for any Specially Serviced Mortgage Loan and take such actions consistent with
the Servicing Standard, the terms hereof and the related Asset Status Report.
The Special Servicer shall not take any action inconsistent with the related
Asset Status Report, unless such action would be required in order to act in
accordance with the Servicing Standard.

     No direction of the Controlling Class Representative (or in the case of the
77 West Wacker Drive Mortgage Loan, the WW Controlling Holder) or the majority
of the Certificateholders shall (a) require or cause the Special Servicer to
violate the terms of a Specially Serviced Mortgage Loan, applicable law or any
provision of this Agreement, including the Special Servicer's obligation to act
in accordance with the Servicing Standard and to maintain the REMIC status of
each REMIC, (b) result in the imposition of a "prohibited transaction" or
"prohibited contribution" tax under the REMIC Provisions or (c) expose the
Master Servicer, the Special Servicer, the Depositor, any of the Mortgage Loan
Sellers, the Trust Fund, the Trustee or the Fiscal Agent or the officers and the
directors of each party to claim, suit or liability or (d) expand the scope of
the Master Servicer's, the Trustee's, the Fiscal Agent's or the Special
Servicer's responsibilities under this Agreement.

     SECTION 3.22   Sub-Servicing Agreements.

     (a) The Master Servicer and the Special Servicer may enter into
Sub-Servicing Agreements to provide for the performance by third parties of any
or all of their respective obligations hereunder, provided that, in each case,
the Sub-Servicing Agreement: (i) is consistent with this Agreement in all
material respects, requires the Sub-Servicer to comply with all of the
applicable conditions of this Agreement and includes events of default with
respect to the Sub-Servicer substantially similar to the Events of Default set
forth in Section 7.01(a) hereof (other than Section 7.01(a)(x) and (xi)) to the
extent applicable (modified to apply to the Sub-Servicer instead of the Master
Servicer); (ii) provides that if the Master Servicer or the Special Servicer, as
the case may be, shall for any reason no longer act in such capacity hereunder
(including, without limitation, by reason of an Event of Default), the Trustee
or its designee may thereupon assume all of the rights and, except to the extent
such obligations arose prior to the date of assumption, obligations of the
Master Servicer or the Special Servicer, as the case may be, under such
agreement or (except with respect only to the Sub-Servicing Agreements in effect
as of the

                                      175
<PAGE>

date of this Agreement) may terminate such subservicing agreement without cause
and without payment of any penalty or termination fee (other than the right of
reimbursement and indemnification); (iii) provides that the Trustee, for the
benefit of the Certificateholders, shall be a third party beneficiary under such
agreement, but that (except to the extent the Trustee or its designee assumes
the obligations of the Master Servicer or the Special Servicer, as the case may
be, thereunder as contemplated by the immediately preceding clause (ii)) none of
the Trustee, the Fiscal Agent, the Trust Fund, any successor Master Servicer or
Special Servicer, as the case may be, or any Certificateholder shall have any
duties under such agreement or any liabilities arising therefrom; (iv) permits
any purchaser of a Mortgage Loan pursuant to this Agreement to terminate such
agreement with respect to such purchased Mortgage Loan at its option and without
penalty, (v) with respect to any Sub-Servicing Agreement entered into by the
Special Servicer, does not permit the Sub-Servicer to enter into or consent to
any modification, waiver or amendment or otherwise take any action on behalf of
the Special Servicer contemplated by Section 3.20 hereof without the consent of
such Special Servicer or conduct any foreclosure action contemplated by Section
3.09 hereof or sale of a Mortgage Loan or REO Property contemplated by Section
3.18 hereof, and (vi) does not permit the Sub-Servicer any direct rights of
indemnification that may be satisfied out of assets of the Trust Fund. In
addition, each Sub-Servicing Agreement entered into by the Master Servicer shall
provide that such agreement shall be subject to Section 3.21 hereof with respect
to any Mortgage Loan that becomes a Specially Serviced Mortgage Loan. The Master
Servicer and the Special Servicer will each be solely liable for all fees owed
by it to any Sub-Servicer with which it has entered into a Sub-Servicing
Agreement, irrespective of whether its compensation under this Agreement is
sufficient to pay those fees. The Master Servicer and the Special Servicer each
shall deliver to the Trustee copies of all Sub-Servicing Agreements, and any
amendments thereto and modifications thereof, entered into by it promptly upon
its execution and delivery of such documents. References in this Agreement to
actions taken or to be taken by the Master Servicer or the Special Servicer
include actions taken or to be taken by a Sub-Servicer on behalf of the Master
Servicer or the Special Servicer, as the case may be; and, in connection
therewith, all amounts advanced by any Sub-Servicer to satisfy the obligations
of the Master Servicer hereunder to make P&I Advances or Servicing Advances
shall be deemed to have been advanced by the Master Servicer out of its own
funds and, accordingly, such P&I Advances or Servicing Advances shall be
recoverable by such Sub-Servicer in the same manner and out of the same funds as
if such Sub-Servicer were the Master Servicer. For so long as they are
outstanding, Advances shall accrue interest in accordance with Sections 3.03(d)
and 4.03(d), such interest to be allocable between the Master Servicer or the
Special Servicer, as the case may be, and such Sub-Servicer as they may agree.
For purposes of this Agreement, the Master Servicer and the Special Servicer
each shall be deemed to have received any payment when a Sub-Servicer retained
by it receives such payment. The Master Servicer and the Special Servicer each
shall notify the other, the Trustee and the Depositor in writing promptly of the
appointment by it of any Sub-Servicer.

     (b) Each Sub-Servicer shall be authorized to transact business in the state
or states in which the related Mortgaged Properties it is to service are
situated, if and to the extent required by applicable law, and shall be an
approved conventional seller/servicer of mortgage loans for FHLMC or FNMA or a
HUD-Approved Servicer.

     (c) The Master Servicer and the Special Servicer, for the benefit of the
Trustee and the Certificateholders, shall (at no expense to the Trustee, the
Certificateholders or the Trust

                                      176
<PAGE>

Fund) monitor the performance and enforce the obligations of their respective
Sub-Servicers under the related Sub-Servicing Agreements. Such enforcement,
including, without limitation, the legal prosecution of claims, termination of
Sub-Servicing Agreements in accordance with their respective terms and the
pursuit of other appropriate remedies, shall be in such form and carried out to
such an extent and at such time as the Master Servicer or the Special Servicer,
as applicable, in its good faith business judgment, would require were it the
owner of the Mortgage Loans. Subject to the terms of the related Sub-Servicing
Agreement, the Master Servicer and the Special Servicer may each have the right
to remove a Sub-Servicer at any time it considers such removal to be in the best
interests of Certificateholders.

     (d) In the event of the resignation, removal or other termination of
KeyCorp Real Estate Capital Markets, Inc. or any successor Master Servicer
hereunder for any reason, the Trustee or other Person succeeding such resigning,
removed or terminated party as Master Servicer, shall elect, with respect to any
Sub-Servicing Agreement in effect as of the date of this Agreement: (i) to
assume the rights and obligations of the Master Servicer under such
Sub-Servicing Agreement and continue the sub-servicing arrangements thereunder
on the same terms (including without limitation the obligation to pay the same
sub-servicing fee); (ii) to enter into a new Sub-Servicing Agreement with such
Sub-Servicer on such terms as the Trustee or other successor Master Servicer and
such Sub-Servicer shall mutually agree (it being understood that such
Sub-Servicer is under no obligation to accept any such new Sub-Servicing
Agreement or to enter into or continue negotiations with the Trustee or other
successor Master Servicer in which case the existing Sub-Servicing Agreement
shall remain in effect); or (iii) to terminate the Sub-Servicing Agreement if
(but only if) an Event of Default (as defined in such Sub-Servicing Agreement)
has occurred and is continuing, in each case without paying any sub-servicer
termination fee.

     Each Sub-Servicing Agreement will provide, among other things, that the
Master Servicer and its successors may at its sole option, terminate any rights
the Sub-Servicer may have thereunder with respect to any or all Mortgage Loans
if Moody's (i) reduces the rating assigned to one or more Classes of the
respective Certificates as a result of the sub-servicing of the Mortgage Loans
by the Sub-Servicer, or (ii) advises the Master Servicer or the Trustee in
writing that it will cause a qualification, downgrade or withdrawal of such
rating due to the continued servicing by the Sub-Servicer.

     (e) Notwithstanding any Sub-Servicing Agreement, the Master Servicer and
the Special Servicer shall remain obligated and liable to the Trustee and the
Certificateholders for the performance of their respective obligations and
duties under this Agreement in accordance with the provisions hereof to the same
extent and under the same terms and conditions as if each alone were servicing
and administering the Mortgage Loans or REO Properties for which it is
responsible.

     (f) The Special Servicer shall not enter into a Sub-Servicing Agreement
unless Moody's has confirmed in writing that the execution of such agreement
will not result in a qualification, downgrade, or withdrawal of the then-current
ratings on the outstanding Certificates or such Sub-Servicing Agreement relates
to a Mortgage Loan or Mortgage Loans (along with any Mortgage Loans previously
sub-serviced pursuant to this section) that represent less than 25% of the
outstanding principal balance of all Specially Serviced Mortgage Loans.

                                      177
<PAGE>

The Special Servicer shall comply with the terms of each such Sub-Servicing
Agreement to the extent the terms thereof are not inconsistent with the terms of
this Agreement and the Special Servicer's obligations hereunder.

     SECTION 3.23   Representations and Warranties of Master Servicer and
Special Servicer.

     (a) The Master Servicer, in such capacity, hereby represents and warrants
to the Trustee, for its own benefit and the benefit of the Certificateholders,
the Depositor and the Special Servicer, as of the Closing Date, that:

          (i) The Master Servicer is a corporation, duly organized, validly
     existing and in good standing under the laws of the State of Ohio, and the
     Master Servicer is in compliance with the laws of each State in which any
     Mortgaged Property is located to the extent necessary to perform its
     obligations under this Agreement, except where the failure to so qualify or
     comply would not have a material adverse effect on the ability of the
     Master Servicer to perform its obligations hereunder.

          (ii) The execution and delivery of this Agreement by the Master
     Servicer, and the performance and compliance with the terms of this
     Agreement by the Master Servicer, will not violate the Master Servicer's

     which, with notice or lapse of time, or both, would constitute a default)
     under, or result in the breach of, any material agreement or other material
     instrument to which it is a party or by which it is bound.

     applicable bankruptcy, liquidation, receivership, insolvency,
     reorganization, moratorium and other laws affecting the enforcement of
     creditors' rights generally and the rights of creditors of banks, and (B)
     general principles of equity, regardless of whether such enforcement is
     considered in a proceeding in equity or at law.

          (v) The Master Servicer is not in violation of, and its execution and
     delivery of this Agreement and its performance and compliance with the
     terms of this Agreement will not constitute a violation of, any law, any
     order or decree of any court or arbiter, or any order, regulation or demand
     of any federal, state or local governmental or regulatory authority, which
     violation, in the Master Servicer's good faith and reasonable judgment, is
     likely to affect materially and adversely either the ability of the Master
     Servicer to perform its obligations under this Agreement or the financial
     condition of the Master Servicer.

     knowledge, threatened, against the Master Servicer that would prohibit the

     approval, authorization or order has not been or cannot be obtained prior
     to the actual performance by the Master Servicer of its obligations under
     this Agreement, the lack of such item would not have a materially adverse
     effect on the ability of the Master Servicer to perform its obligations
     under this Agreement.

to the Trustee, for its own benefit and the benefit of the Certificateholders,

          (v) The Special Servicer is not in violation of, and its execution and

<PAGE>

requirements for such Sub-Servicing Agreements set forth in Sections 3.22(a) and
the second paragraph of 3.22(d) in all material respects.

     SECTION 3.25   Designation of Controlling Class Representative and WW
Controlling Holder.

     (a) The Holders (or, in the case of Book-Entry Certificates, the
Certificate Owners) of Certificates representing more than 50% of the Class
Principal Balance of the Controlling Class shall be entitled in accordance with
this Section 3.25 to select a representative (the "Controlling Class
Representative") having the rights and powers specified in this Agreement
(including those specified in Section 6.11) or to replace an existing
Controlling Class Representative. Upon (i) the receipt by the Trustee of written
requests for the selection of a Controlling Class Representative from the
Holders (or, in the case of Book-Entry Certificates, the Certificate Owners) of
Certificates representing more than 50% of the Class Principal Balance of the
Controlling Class, (ii) the resignation or removal of the Person acting as
Controlling Class Representative or (iii) a determination by the Trustee that
the Controlling Class has changed, the Trustee shall promptly notify the
Depositor and the Holders (and, in the case of Book-Entry Certificates, to the
extent actually known to a Responsible Officer of the Trustee or identified
thereto by the Depository or the Depository Participants, the Certificate
Owners) of the Controlling Class that they may select a Controlling Class
Representative. Such notice shall set forth the process for selecting a
Controlling Class Representative, which shall be the designation of the
Controlling Class Representative by the Holders (or Certificate Owners) of
Certificates representing more than 50% of the Class Principal Balance of the
Controlling Class by a writing delivered to the Trustee. No appointment of any
Person as a Controlling Class Representative shall be effective until such
Person provides the Trustee with written confirmation of its acceptance of such
appointment, an address and telecopy number for the delivery of notices and
other correspondence and a list of officers or employees of such Person with
whom the parties to this Agreement may deal (including their names, titles, work
addresses and telecopy numbers); provided, that the initial Controlling Class
Representative shall be ARCap CMBS Fund REIT, Inc. and no further notice shall
be required for such appointment to be effective.

     (b) Within ten (10) Business Days (or as soon thereafter as practicable if
the Controlling Class consists of Book-Entry Certificates) of receiving a
request therefor from the Master Servicer or Special Servicer, the Trustee shall
deliver to the requesting party the identity of the Controlling Class
Representative and a list of each Holder (or, in the case of Book-Entry
Certificates, to the extent actually known to a Responsible Officer of the
Trustee or identified thereto by the Depository or the Depository Participants,
each Certificate Owner) of the Controlling Class, including, in each case, names
and addresses. With respect to such information, the Trustee shall be entitled
to conclusively rely on information provided to it by the Depository, and the
Master Servicer and the Special Servicer shall be entitled to conclusively rely
on such information provided by the Trustee with respect to any obligation or
right hereunder that the Master Servicer and the Special Servicer may have to
deliver information or otherwise communicate with the Controlling Class
Representative or any of the Holders (or, if applicable, Certificate Owners) of
the Controlling Class. In addition to the foregoing, within two (2) Business
Days of the selection, resignation or removal of a Controlling Class
Representative, the Trustee shall notify the other parties to this Agreement of
such event. The expenses incurred

                                      181
<PAGE>

by the Trustee in connection with obtaining information from the Depository or
Depository Participants with respect to any Book-Entry Certificate shall be
expenses of the Trust Fund payable out of the Certificate Account pursuant to
Section 3.05(a).

     (c) The Controlling Class Representative may at any time resign as such by
giving written notice to the Trustee and to each Holder (or, in the case of
Book-Entry Certificates, Certificate Owner) of the Controlling Class. The
Holders (or, in the case of Book-Entry Certificates, the Certificate Owners) of
Certificates representing more than 50% of the Class Principal Balance of the
Controlling Class shall be entitled to remove any existing Controlling Class
Representative by giving written notice to the Trustee and to such existing
Controlling Class Representative.

     (d) Once a Controlling Class Representative has been selected pursuant to
this Section 3.25 each of the parties to this Agreement and each
Certificateholder (or Certificate Owner, if applicable) shall be entitled to
rely on such selection unless a majority of the Holders (or, in the case of
Book-Entry Certificates, the Certificate Owners) of the Controlling Class, by
aggregate Certificate Principal Balance, or such Controlling Class
Representative, as applicable, shall have notified the Trustee and each other
Holder (or, in the case of Book-Entry Certificates, Certificate Owner) of the
Controlling Class, in writing, of the resignation or removal of such Controlling
Class Representative.

     (e) Any and all expenses of the Controlling Class Representative shall be
borne by the Holders (or, if applicable, the Certificate Owners) of Certificates
of the Controlling Class, pro rata according to their respective Percentage
Interests in such Class, and not by the Trust. Notwithstanding the foregoing, if
a claim is made against the Controlling Class Representative by a Mortgagor with
respect to this Agreement or any particular Mortgage Loan, the Controlling Class
Representative shall immediately notify the Trustee, the Fiscal Agent, the
Master Servicer and the Special Servicer, whereupon (if the Special Servicer or
the Trust Fund are also named parties to the same action and, in the sole
judgment of the Special Servicer, (i) the Controlling Class Representative had
acted in good faith, without negligence or willful misfeasance with regard to
the particular matter, and (ii) there is no potential for the Special Servicer
or the Trust Fund to be an adverse party in such action as regards the
Controlling Class Representative) the Special Servicer on behalf of the Trust
Fund shall, subject to Section 6.03, assume the defense of any such claim
against the Controlling Class Representative. This provision shall survive the
termination of this Agreement and the termination or resignation of the
Controlling Class Representative.

     (f) All rights to, and requirements for, information (including the
delivery of information or access to information) provided to the Controlling
Class Representative contained herein shall also apply to each Companion Holder
with respect to information relating to the related AB Mortgage Loan (other than
with respect to information related to the calculation of the Option Price
related to the related AB Mortgage Loan except to the extent required to be
furnished under the related Intercreditor Agreement).

     (g) The WW Controlling Holder shall be entitled in accordance with this
Section 3.25 to select an advisor (the "77 West Wacker Drive Operating
Advisor"), having the rights and powers (so long as a Control Change Event with
respect to the Class WW Principal

those specified in Section 6.11), or to replace an existing 77 West Wacker Drive
Operating Advisor. Upon (i) the receipt by the Trustee of written requests for
the selection of a 77 West Wacker Drive Operating Advisor from the WW
Controlling Holder, (ii) the resignation or removal of the Person acting as the
77 West Wacker Drive Operating Advisor or (iii) a determination by the Trustee
that the WW Controlling Holder has changed, the Trustee shall promptly notify
the Depositor and the Holders (and, in the case of Book-Entry Certificates, to
the extent actually known to a Responsible Officer of the Trustee or identified
thereto by the Depository or the Depository Participants, the Certificate
Owners) of the Class that includes the WW Controlling Holder that they may
select a 77 West Wacker Drive Operating Advisor. Such notice shall set forth the
process for selecting a 77 West Wacker Drive Operating Advisor, which shall be
the designation of the 77 West Wacker Drive Operating Advisor by the WW
Controlling Holder in writing delivered to the Trustee. No appointment of any
Person as a 77 West Wacker Drive Operating Advisor shall be effective until such
Person provides the Trustee with written confirmation of its acceptance of such
appointment, an address and telecopy number for the delivery of notices and
other correspondence and a list of officers or employees of such Person with
whom the parties to this Agreement may deal (including their names, titles, work
addresses and telecopy numbers).

     (h) Within ten (10) Business Days (or as soon thereafter as practicable if
the Class that includes the WW Controlling Holder consists of Book-Entry
Certificates) of receiving a request therefor from the Master Servicer or
Special Servicer, the Trustee shall deliver to the requesting party the identity
of the 77 West Wacker Drive Operating Advisor and a list of each Holder (or, in
the case of Book-Entry Certificates, to the extent actually known to a
Responsible Officer of the Trustee or identified thereto by the Depository or
the Depository Participants, each Certificate Owner) of the class that includes
the WW Controlling Holder, including, in each case, names and addresses. With
respect to such information, the Trustee shall be entitled to conclusively rely
on information provided to it by the Depository, and the Master Servicer and the
Special Servicer shall be entitled to conclusively rely on such information
provided by the Trustee with respect to any obligation or right hereunder that
the Master Servicer and the Special Servicer may have to deliver information or
otherwise communicate with the 77 West Wacker Drive Operating Advisor or any of
the Holders (or, if applicable, Certificate Owners) of the Class that includes
the WW Controlling Holder. In addition to the foregoing, within two (2) Business
Days of the selection, resignation or removal of a 77 West Wacker Drive
Operating Advisor, the Trustee shall notify the other parties to this Agreement
of such event. The expenses incurred by the Trustee in connection with obtaining
information from the Depository or Depository Participants with respect to any
Book-Entry Certificate shall be expenses of the Trust Fund payable out of the
Certificate Account pursuant to Section 3.05(a).

     (i) A 77 West Wacker Drive Operating Advisor may at any time resign as such
by giving written notice to the Trustee and to each Holder (or, in the case of
Book-Entry Certificates, Certificate Owner) of the Class that includes the WW
Controlling Holder. The WW Controlling Holder shall be entitled to remove any
existing 77 West Wacker Drive Operating Advisor by giving written notice to the
Trustee and to such existing 77 West Wacker Drive Operating Advisor.

     (j) Once a 77 West Wacker Drive Operating Advisor has been selected
pursuant to this Section 3.25 each of the parties to this Agreement and each
Certificateholder (or

                                      183
<PAGE>

Certificate Owner, if applicable) shall be entitled to rely on such selection
unless the WW Controlling Holder shall have notified the Trustee and each other
Holder (or, in the case of Book-Entry Certificates, Certificate Owner) of the
Class that includes the WW Controlling Holder, in writing, of the resignation or
removal of such 77 West Wacker Drive Operating Advisor.

     (k) Any and all expenses of the 77 West Wacker Drive Operating Advisor
shall be borne by the WW Controlling Holder. Notwithstanding the foregoing, if a
claim is made against the 77 West Wacker Drive Operating Advisor by a Mortgagor
with respect to this Agreement or any particular Mortgage Loan, the 77 West
Wacker Drive Operating Advisor shall immediately notify the Trustee, the Fiscal
Agent, the Master Servicer and the Special Servicer, whereupon (if the Special
Servicer or the Trust Fund are also named parties to the same action and, in the
sole judgment of the Special Servicer, (i) the 77 West Wacker Drive Operating
Advisor had acted in good faith, without negligence or willful misfeasance with
regard to the particular matter, and (ii) there is no potential for the Special
Servicer or the Trust Fund to be an adverse party in such action as regards the
77 West Wacker Drive Operating Advisor) the Special Servicer on behalf of the
Trust Fund shall, subject to Section 6.03, assume the defense of any such claim
against the 77 West Wacker Drive Operating Advisor. This provision shall survive
the termination of this Agreement and the termination or resignation of the 77
West Wacker Drive Operating Advisor.

     SECTION 3.26   Servicing and Administration of the Pooled Mortgage Loans
and the Related Companion Loans.

     (a) Each Subordinate Companion Loan and, unless it is included in the
Series 2003-C5 Securitization, the Fairfield Commons Pari Passu Companion Loan,
shall be serviced and administered hereunder as if it was a Mortgage Loan for so
long as the related Pooled Mortgage Loan or REO Loan is an asset of the Trust
Fund, including for purposes of: (i) the application of the Servicing Standard,
as if the holder of such Companion Loan was the Holder of a separate Class of
Certificates backed solely by such Companion Loan; (ii) determining whether a
Companion Loan is a Specially Serviced Mortgaged Loan; and (iii) the payment of
the Special Servicing Fee and other forms of compensation to the Special
Servicer; provided, however, notwithstanding anything herein to the contrary:
(i) prior to certain defaults identified in the related Intercreditor Agreement,
all payments on each Subordinate Companion Loan will be paid directly to the
related Companion Holder, in accordance with the provisions of the related
Intercreditor Agreement, and will not be collected by the Master Servicer
hereunder and no party hereto shall make any P&I Advances with respect to such
Companion Loan or otherwise for the benefit of the holder thereof; (ii) if any
of the events which would result in a Companion Loan constituting a Specially
Serviced Mortgaged Loan were to occur, then the Companion Loan and related
Pooled Mortgage Loan shall be treated collectively as a single Specially
Serviced Mortgage Loan with the consent of the Controlling Class Representative
(so long as the Controlling Class Representative is not an affiliate of the
related Mortgage Loan Seller or the Companion Holder), which consent shall be
deemed to have been provided if the Controlling Class Representative does not
respond to a request therefore within five Business Days of its receipt of such
request, including for purposes of application of the Servicing Standard, until
all such events with respect to the Companion Loan have ceased to exist; (iii)
if any of the events which would result in a Pooled Mortgage Loan constituting a
Specially

                                      184
<PAGE>

Serviced Mortgaged Loan were to occur, then such Pooled Mortgage Loan and
related Companion Loan shall be treated collectively as a single Specially
Serviced Mortgage Loan, including for purposes of application of the Servicing
Standard, until both such loans have become Corrected Mortgage Loans; (iv) all
amounts received on or with respect to such Companion Loan and the corresponding
Pooled Mortgage Loan or on or with respect to any related REO Property shall be
allocable between the holder of such Companion Loan and the Trust Fund, as
holder of the corresponding Pooled Mortgage Loan, in accordance with the terms
of the related Intercreditor Agreement, with any amounts so allocable to the
corresponding Pooled Mortgage Loan to be deposited in the Companion Loan
Custodial Account for application as contemplated by Section 3.04 and 3.05 (or,
if received on any related REO Property, in the REO Account for application as
contemplated by Section 3.16) and any amounts allocable to such Companion Loan
to be distributed by the Master Servicer to the holder of such Companion Loan in
accordance with the related Intercreditor Agreement (except that any amounts
allocable under such Intercreditor Agreement for purposes of paying or
reimbursing any party hereto or the Trust Fund for any Advances, interest on
Advances, servicing or special servicing compensation or Additional Trust Fund
Expenses related to such Companion Loan (subject to the provisions of the
immediately following clause (v)), the corresponding Pooled Mortgage Loan and/or
any related REO Property, including any such items which were previously paid
out of amounts allocable to the corresponding Pooled Mortgage Loan, shall be
deemed to have been received and allocable to the corresponding Pooled Mortgage
Loan and shall be deposited into the Companion Loan Custodial Account for
application as contemplated by Section 3.04 and 3.05 (or, if received on any
related REO Property, in the REO Account for application as contemplated by
Section 3.16)); (v) no Trustee Fees will be payable with respect to matters
affecting such Companion Loan; (vi) except to the extent that the corresponding
Pooled Mortgage Loan is affected or is otherwise required by the related loan
documents, this Agreement or the related Intercreditor Agreement, no
confirmation will be required of the Rating Agencies with respect to such
Companion Loan; (vii) all statements, reports and written or electronic
information forwarded by any party hereto to the Controlling Class
Representative shall also be contemporaneously forwarded to the holder of such
Companion Loan (but only to the extent that such statements, reports and other
information directly relate to such Companion Loan and the exclusive of any
information, statements or reports related to the calculation of the Option
Price for the Pooled Mortgage Loan); (viii) the Master Servicer shall, to the
extent permitted by the related Intercreditor Agreement, make claims for
reimbursement from the holder of the related Companion Loan, in connection with
related Advances, interest on Advances and other related expenses so as to
minimize the total amount of the withdrawals on the Certificate Account for such
items; and (ix) in no event shall such Companion Loan be taken into account for
purposes of determining distributions on the actual Certificates. Servicing and
administration of each Companion Loan shall continue hereunder for so long as
the corresponding Pooled Mortgage Loan or any related REO Property is part of
the Trust Fund or provided that any amounts payable by the holder of such
Companion Loan to or for the benefit of the Trust Fund or any party hereto in
accordance with the related Intercreditor Agreement after such period remain due
and owing. Notwithstanding anything herein to the contrary, for so long as the
Fairfield Commons Pari Passu Companion Loan is included in the Series 2003-C5
Securitization, the Fairfield Commons Total Loan will be serviced under the
Series 2003-C5 Pooling and Servicing Agreement as contemplated in the Fairfield
Commons Intercreditor Agreement and Section 3.01 of this Agreement.

                                      185
<PAGE>

     (b) The servicing and administration of each Pooled Mortgage Loan and the
corresponding Companion Loan shall be subject to and shall be consistent with
the terms and conditions of the related Intercreditor Agreement and the
Servicing Standard so long as such terms and conditions do not conflict with the
REMIC Provisions. The Trustee, the Master Servicer and the Special Servicer each
acknowledge that each Pooled Mortgage Loan and its related Companion Loan shall
be serviced and administered pursuant to this Agreement and the related
Intercreditor Agreement, except that with respect to the Fairfield Commons Total
Loan, for so long as the Fairfield Commons Pari Passu Companion Loan is included
in the Series 2003-C5 Securitization, the Fairfield Commons Total Loan will be
serviced under the Series 2003-C5 Pooling and Servicing Agreement as
contemplated in the Fairfield Commons Intercreditor Agreement and Section 3.01
of this Agreement. Except with respect to the exclusion of information related
to the calculation of the Option Price of a Pooled Mortgage Loan (to the extent
not required to be furnished pursuant to the terms of the related Intercreditor
Agreement), in the event of conflict between the related Intercreditor Agreement
and this Agreement, the related Intercreditor Agreement shall control.

     (c) Payments of amounts allocable to a Companion Loan shall be payable to
the holder of such Companion Loan in accordance with the instructions of such
holder delivered pursuant to the terms of the related Intercreditor Agreement.

     (d) It is hereby acknowledged and agreed that, to the extent that the
holder of each Companion Loan may purchase the corresponding Pooled Mortgage
Loan or related REO Property out of the Trust Fund at the price and in
accordance with the terms and conditions specified in the related Intercreditor
Agreement, such right shall have priority over any provision of Section 3.18(c)
or Section 3.18(i). If a Pooled Mortgage Loan or REO Property is purchased by
the related Companion Holder, repurchased by the applicable Mortgage Loan Seller
or otherwise ceases to be subject to this Agreement, the related Companion Loan
will no longer be subject to this Agreement. The price paid in connection with
such purchase shall be deposited into the Certificate Account, and the Trustee,
upon receipt of a Request for Release and receipt of an Officer's Certificate
from the Master Servicer to the effect that such deposit has been made, shall
release or cause to be released to the holder of such Companion Loan the related
Mortgage File, and shall execute and deliver such instruments of transfer or
assignment, in each case without recourse (except as provided in the related
Intercreditor Agreement), as shall be provided to it and are reasonably
necessary to vest in the holder of such Companion Loan the ownership of the
corresponding Pooled Mortgage Loan. In connection with such purchase, the Master
Servicer and the Special Servicer shall each deliver to the holder of such
Companion Loan the respective portion of the related Servicing File held by it.

     (e) Transfers of each Companion Loan shall be governed by the related
Intercreditor Agreement. Neither the Trustee, the Master Servicer nor the Trust
Fund shall acquire a Companion Loan. If the Master Servicer has discretion
regarding the transfer of a Companion Loan under the related Intercreditor
Agreement, the Master Servicer may only consent to a transfer of such Companion
Loan with the consent of the Controlling Class Representative.

     (f) For the purposes of this Agreement, receipt by the Master Servicer or
the Special Servicer of any amounts relating to a Pooled Mortgage Loan or the
Trust Fund's share of

                                      186
<PAGE>

any amounts relating to the underlying Mortgaged Property shall be deemed to be
amounts received on behalf of the Trust Fund.

     (g) The Master Servicer shall provide to each Companion Holder any reports
or notices required to be delivered to such Companion Holder pursuant to the
related Intercreditor Agreement. Any report prepared by the Master Servicer
pursuant to the terms of any Intercreditor Agreement shall also be delivered to
the Controlling Class Representative insofar as such report relates to the
related Companion Loan.

     (h) If the Fairfield Commons Total Loan becomes specially serviced in
accordance with the terms of the Series 2003-C5 Pooling and Servicing Agreement
and, pursuant to the Fairfield Commons Intercreditor Agreement, the Series
2003-C5 Trustee or other holder of the Fairfield Commons Pari Passu Companion
Loan or its servicing agent notifies the Master Servicer that the Trust Fund, as
holder of the Fairfield Commons Pooled Mortgage Loan, or its designee, is
entitled to certain consultation rights with respect to the Fairfield Commons
Total Loan or any related REO Loan, then the Master Servicer, as applicable,
shall promptly within one Business Day so notify the Special Servicer and the
Controlling Class Representative. For so long as the Trust Fund or its designee
is entitled to such consultation rights under the terms of the Fairfield Commons
Intercreditor Agreement, the Special Servicer shall exercise such consultation
rights in consultation with the Controlling Class Representative.

     In addition, if pursuant to the terms of the Fairfield Commons
Intercreditor Agreement, upon the occurrence of an event of default under the
Fairfield Commons Total Loan, the Trustee on behalf of the Trust Fund, as holder
of the Fairfield Commons Pooled Mortgage Loan, has the right but not the
obligation to purchase the Fairfield Commons Pari Passu Companion Loan at the
price set forth in the Fairfield Commons Intercreditor Agreement then the
Trustee shall promptly so notify all of the Holders of the Controlling Class.
Any single Certificateholder or group of Certificateholders entitled to a
majority of the Voting Rights allocated to the Controlling Class may indicate to
the Trustee in writing its or their intent to purchase the Fairfield Commons
Pari Passu Companion Loan in accordance with the Fairfield Commons Intercreditor
Agreement and/or any corresponding provision of the Series 2003-C5 Pooling and
Servicing Agreement, whereupon the Trustee shall designate such
Certificateholder or group of Certificateholders as its designee to so purchase
the Fairfield Commons Pari Passu Companion Loan, in its or their individual
capacity and not on behalf of the Trust, in accordance with the Fairfield
Commons Intercreditor Agreement and/or any corresponding provision of the Series
2003-C5 Pooling and Servicing Agreement. Any such purchase will be subject to
all applicable provisions of, and at the price set forth in, the Fairfield
Commons Intercreditor Agreement (including those provisions that mandate who may
be a permitted transferee of the Fairfield Commons Pari Passu Companion Loan).
Upon any such purchase, such Certificateholder or group of Certificateholders
shall constitute the "A-1 Noteholder" under the Fairfield Commons Intercreditor
Agreement, and the Fairfield Commons Total Loan shall be serviced and
administered in accordance with this Agreement. The Trustee shall reasonably
cooperate with such Certificateholder or Certificateholders in effecting such
purchase.

     (a) Any and all Default Charges that are actually received by or on behalf
of the Trust with respect to any Mortgage Loan or REO Loan, shall be applied for
the following purposes and in the following order, in each case to the extent of
the remaining portion of such Default Charges:

          first, to pay to the Fiscal Agent, the Trustee, the Master Servicer or
     the Special Servicer, in that order, any interest due and owing to such
     party on outstanding Advances made thereby with respect to such Mortgage
     Loan or REO Loan, as the case may be;

          second, to reimburse the Trust for any interest on Advances paid to
     the Fiscal Agent, the Trustee, the Master Servicer or the Special Servicer
     since the Closing Date with respect to such Mortgage Loan or REO Loan, as
     the case may be, which interest was paid from a source other than Default
     Charges collected on such Mortgage Loan or REO Loan, as the case may be;

          third, to pay any outstanding expense incurred by the Special Servicer
     in connection with inspecting the related Mortgaged Property or REO
     Property, as applicable, pursuant to Section 3.12;

          fourth, to reimburse the Trust for any expenses reimbursed to the
     Special Servicer since the Closing Date in connection with inspecting the
     related Mortgaged Property or REO Property, as applicable, pursuant to
     Section 3.12, which expenses were previously paid from a source other than
     Default Charges collected on such Mortgage Loan or REO Loan, as the case
     may be;

          fifth, to pay the appropriate party for any other outstanding expense
     (exclusive of Special Servicing Fees, Workout Fees and Liquidation Fees)
     incurred thereby with respect to such Mortgage Loan or REO Loan, as the
     case may be, which expense, if not paid out of Default Charges collected on
     such Mortgage Loan or REO Mortgage Loan, as the case may be, will likely
     become an Additional Trust Fund Expense;

          sixth, to reimburse the Trust for any other Additional Trust Fund
     Expense (exclusive of Special Servicing Fees, Workout Fees and Liquidation
     Fees) paid to the appropriate party since the Closing Date with respect to
     such Mortgage Loan or REO Mortgage Loan, as the case may be, which
     Additional Trust Fund Expense was paid from a source other than Default
     Charges collected on such Mortgage Loan or REO Loan, as the case may be;
     and

          seventh, to pay any remaining portion of such Default Charges as
     Additional Master Servicing Compensation to the Master Servicer, if such
     Default Charges were collected when the loan was a performing Mortgage
     Loan, and otherwise to pay any remaining portion of such Default Charges as
     Additional Special Servicing Compensation to the Special Servicer.

     (b) Default Charges applied to reimburse the Trust pursuant to any of
clause second, clause fourth or clause sixth of Section 3.27(a) are intended to
be available for distribution on the Certificates pursuant to Section 4.01(a)
and Section 4.01(b), subject to

                                      188
<PAGE>

application pursuant to Section 3.05(a) or 3.05(b) for any items payable out of
general collections on the Mortgage Pool. Default Charges applied to reimburse
the Trust pursuant to any of clause second, clause fourth or clause sixth of
Section 3.27(a) shall be deemed to offset payments of interest on Advances,
costs of property inspections or, except for Special Servicing Fees, Workout
Fees and Liquidation Fees, other Additional Trust Fund Expenses (depending on
which clause is applicable) in the chronological order in which they were made
or incurred with respect to the subject Mortgage Loan or REO Loan (whereupon
such interest on Advances, costs of property inspections or, except for Special
Servicing Fees, Workout Fees and Liquidation Fees, other Additional Trust Fund
Expenses (depending on which clause is applicable) shall thereafter be deemed to
have been paid out of Default Charges).

     SECTION 3.28   Controlling Class Representative Contact with Servicer.

     No less often than on a monthly basis, each of the Master Servicer and the
Special Servicer shall, without charge, make a knowledgeable Servicing Officer
via telephone available to verbally answer questions from the Controlling Class
Representative regarding the performance and servicing of the Mortgage Loans
and/or REO Properties for which the Master Servicer or the Special Servicer, as
the case may be, is responsible. Any such telephone contact shall be conditioned
on the Controlling Class Representative's delivery to the Master Servicer of an
agreement substantially in the form of Exhibit I-1.

          (xliv) to distributions of interest to the Holders of the Class P

     the extent not previously paid, for all prior Distribution Dates;

          (xlv) after the Class Principal Balance of the Class N Certificates
     has been reduced to zero, to distributions of principal to the Holders of
     the Class P Certificates, in an amount (not to exceed the Class Principal
     Balance of the Class P Certificates outstanding immediately prior to such
     Distribution Date) equal to the entire Principal Distribution Amount for
     such Distribution Date (net of any portion thereof distributed on such
     Distribution Date to the Holders of any other Class of Certificates
     pursuant to any prior clause of this Section 4.01(a));

          (xlvi) to distributions to the Holders of the Class P Certificates, in

     in respect of the Class Q Certificates for such Distribution Date and, to
     the extent not previously paid, for all prior Distribution Dates;

          (xlviii) after the Class Principal Balance of the Class P Certificates

     Distribution Date to the Holders of any other Class of Certificates
     pursuant to any prior clause of this Section 4.01(a));

          (xlix) to distributions to the Holders of the Class Q Certificates, in

<PAGE>

          (l) to make distributions to the Holders of the Class R-II
     Certificates, in an amount equal to the excess, if any, of (A) the
     aggregate distributions deemed made in respect of the REMIC I Regular
     Interests on such Distribution Date pursuant to Section 4.01(h) and
     4.01(q), over (B) the aggregate distributions made in respect of the
     Regular Certificates on such Distribution Date pursuant to clauses (i)
     through (xlix) above;

provided that on each Distribution Date after the aggregate of Class Principal
Balances of each Class of Subordinated Certificates has been reduced to zero,
the payments of principal to be made as contemplated by clauses (ii), (iii),
(iv), (v) and (vi) above with respect to the Class A Certificates will be made
to the Holders of the respective Classes of such Class A Certificates up to an
amount equal to, and pro rata as among such Classes in accordance with, the
respective then outstanding Class Principal Balances of such Classes of
Certificates and without regard to Loan Group or the Principal Distribution
Amount for such Distribution Date. Distributions in reimbursement of Realized
Losses and Additional Trust Fund Expenses previously allocated to a Class of
Certificates shall not constitute distributions of principal and shall not
result in reduction of the related Class Principal Balance. All references to
"Available Distribution Amount", "Loan Group 1 Available Distribution Amount"
and "Loan Group 2 Available Distribution Amount" above in this Section 4.01(a)
mean the Available Distribution Amount, the Loan Group 1 Available Distribution
Amount and the Loan Group 2 Available Distribution Amount, respectively, net of
any portion thereof distributable on the Class WW Certificates pursuant to
Section 1.02, this Section 4.01 or Section 9.01.

     All distributions of interest made in respect of the Class XC and Class XP
Certificates on any Distribution Date pursuant to clause (i) above, shall be
deemed to have been made in respect of all the Components of such Class, pro
rata in accordance with the respective amounts of interest that would be payable
on such Components on such Distribution Date based on the Class XC and Class XP
Strip Rate, as applicable, of such Component multiplied by its Component
Notional Amount, less an allocable portion of any Prepayment Interest Shortfall,
together with any amounts thereof remaining unpaid from previous Distribution
Dates.

     On each Distribution Date, to the extent of the 77 West Wacker Drive
Available Distribution Amount remaining after the distributions in respect of
the 77 West Wacker Drive Pooled Portion pursuant to Section 4.01(k)(i)-(iii) or
Section 4.01(l)(i)-(iii), as applicable, the Trustee shall distribute to the
Holders of the Class WW-X, Class WW-1, Class WW-2 and Class WW-3 Certificates
the amounts distributed in respect of the 77 West Wacker Drive Mortgage Loan as
specified in Section 4.01(k)(iv)-(xii) or Section 4.01(l)(iv)-(xii), as
applicable.

     (b) On each Distribution Date, the Trustee shall withdraw from the
Distribution Account any amounts that represent Prepayment Premiums and/or Yield
Maintenance Charges actually collected on the Mortgage Loans and any REO Loans
(including, in either case, the 77 West Wacker Drive Mortgage Loan) during the
related Collection Period and shall be deemed to distribute such Prepayment
Premiums and/or Yield Maintenance Charges from REMIC I to REMIC II in respect of
REMIC I Regular Interest LA-1-1 (whether or not such Class has received all
distributions of interest and principal to which it is entitled), and then shall
distribute each such Prepayment Premium and/or Yield Maintenance Charge, as
additional yield, as follows:

                                      197
<PAGE>

          (i) First, to the Holders of the respective Classes of Sequential Pay
     Certificates (other than any Excluded Class thereof) entitled to
     distributions of principal pursuant to Section 4.01(a) on such Distribution
     Date, up to an amount equal to, and pro rata based on, the Additional Yield
     and Prepayment Amount for each such Class of Certificates for such
     Distribution Date with respect to the subject Prepayment Premium or Yield
     Maintenance Charge, as the case may be; and

          (ii) Second, to the Holders of the Class XC Certificates, to the
     extent of any remaining portion of the subject Yield Maintenance Charge or
     Prepayment Premium, as the case may be.

     On each Distribution Date, subject, in the case of AB Mortgage Loans, to
the terms of the related Intercreditor Agreement, the Trustee shall withdraw
from the Additional Interest Account any amounts that represent (A) Additional
Interest actually collected during the related Collection Period on the ARD
Loans and any related REO Loans that are Merrill Mortgage Loans and shall
distribute such amounts among the Holders of the Class Z-I Certificates pro rata
in accordance with their respective Percentage Interests of such Class, and (B)
Additional Interest actually collected during the related Collection Period on
the ARD Loans and any related REO Loans that are KeyBank Mortgage Loans and
shall distribute such amounts among the Holders of the Class Z-II Certificates
pro rata in accordance with their respective Percentage Interests of such Class.

     (c) All distributions made with respect to each Class on each Distribution
Date shall be allocated pro rata among the outstanding Certificates in such
Class based on their respective Percentage Interests. Except as otherwise
provided below, all such distributions with respect to each Class on each
Distribution Date shall be made to the Certificateholders of the respective
Class of record at the close of business on the related Record Date and shall be
made by wire transfer of immediately available funds to the account of any such
Certificateholder at a bank or other entity having appropriate facilities
therefor, if such Certificateholder shall have provided the Trustee with wiring
instructions no less than five Business Days prior to the related Record Date
(which wiring instructions may be in the form of a standing order applicable to
all subsequent Distribution Dates), or otherwise by check mailed to the address
of such Certificateholder as it appears in the Certificate Register. The final
distribution on each Certificate (determined, in the case of a Sequential Pay
Certificate or Class WW Principal Balance Certificate, without regard to any
possible future reimbursement of any Realized Loss or Additional Trust Fund
Expense previously allocated to such Certificate, but taking into account
possible future distributions of Additional Interest) will be made in a like
manner, but only upon presentation and surrender of such Certificate at the
offices of the Certificate Registrar or such other location specified in the
notice to Certificateholders of such final distribution. Prior to any
termination of the Trust Fund pursuant to Section 9.01, any distribution that is
to be made with respect to a Certificate in reimbursement of a Realized Loss or
Additional Trust Fund Expense previously allocated thereto, which reimbursement
is to occur after the date on which such Certificate is surrendered as
contemplated by the preceding sentence, will be made by check mailed to the
address of the Certificateholder that surrendered such Certificate as such
address last appeared in the Certificate Register or to any other address of
which the Trustee was subsequently notified in writing. If such check is
returned to the Trustee, the Trustee, directly or through an agent, shall take
such reasonable steps to contact the related Holder and deliver such

                                      198
<PAGE>

check as it shall deem appropriate. Any funds in respect of a check returned to
the Trustee shall be set aside by the Trustee and held uninvested in trust and
credited to the account of the appropriate Holder. The costs and expenses of
locating the appropriate Holder and holding such funds shall be paid out of such
funds. No interest shall accrue or be payable to any former Holder on any amount
held in trust hereunder. If the Trustee has not, after having taken such
reasonable steps, located the related Holder by the second anniversary of the
initial sending of a check, the Trustee shall, subject to applicable law,
distribute the unclaimed funds to the Holders of the Class R-II Certificates.

     (d) Each distribution with respect to a Book-Entry Certificate shall be
paid to the Depository, as Holder thereof, and the Depository shall be
responsible for crediting the amount of such distribution to the accounts of its
Depository Participants in accordance with its normal procedures. Each
Depository Participant shall be responsible for disbursing such distribution to
the related Certificate Owners that it represents and to each indirect
participating brokerage firm (a "brokerage firm" or "indirect participating
firm") for which it acts as agent. Each brokerage firm shall be responsible for
disbursing funds to the related Certificate Owners that it represents. None of
the Trustee, the Certificate Registrar, the Depositor or the Master Servicer
shall have any responsibility therefor except as otherwise provided by this
Agreement or applicable law. The Trustee and the Depositor shall perform their
respective obligations under a Letter of Representations among the Depositor,
the Trustee and the Initial Depository dated as of the Closing Date.

     (e) The rights of the Certificateholders to receive distributions from the
proceeds of the Trust Fund in respect of the Certificates, and all rights and
interests of the Certificateholders in and to such distributions, shall be as
set forth in this Agreement. Neither the Holders of any Class of Certificates
nor any party hereto shall in any way be responsible or liable to the Holders of
any other Class of Certificates in respect of amounts properly previously
distributed on the Certificates.

     (f) Except as otherwise provided in Section 9.01, whenever the Trustee
receives written notification of or expects that the final distribution with
respect to any Class of Certificates (determined without regard to any possible
future reimbursement of any Realized Loss or Additional Trust Fund Expense
previously allocated to such Class of Certificates) will be made on the next
Distribution Date, the Trustee shall, no later than five days after the related
Determination Date, mail to each Holder of record on such date of such Class of
Certificates a notice to the effect that:

          (i) the Trustee expects that the final distribution with respect to
     such Class of Certificates will be made on such Distribution Date but only
     upon presentation and surrender of such Certificates at the office of the
     Certificate Registrar or at such other location therein specified, and

          (ii) no interest shall accrue on such Certificates from and after such
     Distribution Date.

Any funds not distributed to any Holder or Holders of Certificates of such Class
on such Distribution Date because of the failure of such Holder or Holders to
tender their Certificates

                                      199
<PAGE>

shall, on such date, be set aside and held uninvested in trust and credited to
the account or accounts of the appropriate non-tendering Holder or Holders. If
any Certificates as to which notice has been given pursuant to this Section
4.01(f) shall not have been surrendered for cancellation within six months after
the time specified in such notice, the Trustee shall mail a second notice to the
remaining non-tendering Certificateholders to surrender their Certificates for
cancellation in order to receive the final distribution with respect thereto. If
within one year after the second notice all such Certificates shall not have
been surrendered for cancellation, the Trustee, directly or through an agent,
shall take such steps to contact the remaining non-tendering Certificateholders
concerning the surrender of their Certificates as it shall deem appropriate. The
costs and expenses of holding such funds in trust and of contacting such
Certificateholders following the first anniversary of the delivery of such
second notice to the non-tendering Certificateholders shall be paid out of such
funds. No interest shall accrue or be payable to any former Holder on any amount
held in trust pursuant to this paragraph. If all of the Certificates shall not
have been surrendered for cancellation by the second anniversary of the delivery
of the second notice, the Trustee shall, subject to applicable law, distribute
to the Holders of the Class R-II Certificates all unclaimed funds and other
assets which remain subject thereto.

     (g) Notwithstanding any other provision of this Agreement, the Trustee
shall comply with all federal income tax withholding requirements respecting
payments to Certificateholders of interest or original issue discount that the
Trustee reasonably believes are applicable under the Code. The Certificate
Registrar shall promptly provide the Paying Agent with any IRS Form W-8BEN or
W-ECI upon its receipt thereof. The consent of Certificateholders shall not be
required for such withholding. If the Trustee does withhold any amount from
interest or original issue discount payments or advances thereof to any
Certificateholder pursuant to federal income tax withholding requirements, the
Trustee shall indicate the amount withheld to such Certificateholders.

     (h) All distributions made in respect of any Class of Sequential Pay
Certificates on each Distribution Date pursuant to Section 4.01(a) or Section
9.01 shall be deemed to have first been distributed from REMIC I to REMIC II in
respect of its Corresponding REMIC I Regular Interest set forth in the
Preliminary Statement hereto; provided, however, that distributions of principal
with respect to the Class A-1 Certificates shall be deemed to have first been
distributed from REMIC I to REMIC II in respect of REMIC I Regular Interest
LA-1-1 until its REMIC I Principal Balance is reduced to zero, and then to REMIC
Regular Interest LA-1-2; provided further, that distributions of principal with
respect to the Class A-2 Certificates shall be deemed to have first been
distributed from REMIC I to REMIC II in respect of REMIC I Regular Interest
LA-2-1 until its REMIC I Principal Balance is reduced to zero and then to REMIC
I Regular Interest LA-2-2 until its REMIC I Principal Balance is reduced to zero
and then to REMIC I Regular Interest LA-2-3; provided further, that
distributions of principal with respect to the Class A-3 Certificates shall be
deemed to have first been distributed from REMIC I to REMIC II in respect of
REMIC I Regular Interest LA-3-1 until its REMIC I Principal Balance is reduced
to zero and then to REMIC I Regular Interest LA-3-2 until its REMIC I Principal
Balance is reduced to zero and then to REMIC I Regular Interest LA-3-3 until its
REMIC I Principal Balance is reduced to zero and then to REMIC I Regular
Interest LA-3-4; provided further, that distributions of principal with respect
to the Class A-4 Certificates shall be deemed to have first been distributed
from REMIC I to REMIC II in respect of REMIC I Regular Interest

                                      200

LA-4-1 until its REMIC I Principal Balance is reduced to zero and then to REMIC
I Regular Interest LA-4-2; provided further, that distributions of principal
with respect to the Class A-1A Certificates shall be deemed to have first been
distributed from REMIC I to REMIC II in respect of REMIC I Regular Interest
LA-1-A1-1 until its REMIC I Principal Balance is reduced to zero and then to
REMIC I Regular Interest LA-1A-2 until its REMIC I Principal Balance is reduced

Balance is reduced to zero and then to REMIC I Regular Interest LA-1A-4 until
its REMIC I Principal Balance is reduced to zero and then to REMIC I Regular

reduced to zero and then to REMIC I Regular Interest LA-1A-7 until its REMIC I
Principal Balance is reduced to zero and then to REMIC I Regular Interest
LA-1A-8; provided further, that distributions of principal with respect to the
Class D Certificates shall be deemed to have first been distributed from REMIC I
to REMIC II in respect of REMIC I Regular Interest LD-1 until its REMIC I
Principal Balance is reduced to zero and then to REMIC I Regular Interest LD-2
until its REMIC I Principal Balance is reduced to zero and then to REMIC I

Balance is reduced to zero and then to REMIC I Regular Interest LG-2 until its
REMIC I Principal Balance is reduced to zero; and provided further, that
distributions of principal with respect to the Class J Certificates shall be
deemed to have first been distributed from REMIC I to REMIC II in respect of
REMIC I Regular Interest LJ-1 until its REMIC I Principal Balance is reduced to
zero and then to REMIC I Regular Interest LJ-2 until its REMIC I Principal
Balance is reduced to zero. All distributions made in respect of the Class XC
and Class XP Certificates on each Distribution Date pursuant to Section 4.01(a)
or Section 9.01, and allocable to any particular Component of such Class of
Certificates in accordance with the next to last paragraph of Section 4.01(a),
shall be deemed to have first been distributed from REMIC I to REMIC II in
respect of such Component's Corresponding REMIC I Regular Interest. In each
case, if such distribution on any such Class of Regular Certificates was a
distribution of interest or principal or in reimbursement of previously
allocated Realized Losses and Additional Trust Fund Expenses in respect of such
Class of Regular Certificates, then the corresponding distribution deemed to be
made on a REMIC I Regular Interest pursuant to the preceding two sentences shall
be deemed to also be a distribution of interest or principal or in reimbursement
of previously allocated Realized Losses and Additional Trust Fund Expenses, as
the case may be, in respect of such REMIC I Regular Interest; provided, however,
with respect to Realized Losses and Additional Trust Fund Expenses allocated to
the Class A-1 Certificates, such corresponding distribution shall be deemed to
be a distribution with respect to REMIC I Regular Interest LA-1-1 and REMIC I
Regular Interest LA-1-2 allocated pro rata based on their respective REMIC I
Principal Balances; provided, further, with respect to Realized Losses and
Additional Trust Fund Expenses allocated to the Class A-2 Certificates, such

REMIC I Regular Interest L-A-2-1, REMIC I Regular Interest L-A-2-2 and REMIC
Regular Interest L-A-2-3 allocated pro rata based upon their respective REMIC I
Principal Balances; provided, further, with respect to Realized Losses and
Additional Trust Fund Expenses allocated to the Class A-3 Certificates, such

REMIC I Regular Interest LA-3-1, REMIC I Regular Interest LA-3-2, REMIC Regular
Interest LA-3-3

                                      201

corresponding distribution shall be deemed to be a distribution with respect to
REMIC I Regular Interest LA-4-1 and REMIC I Regular Interest LA-4-2 allocated

provided further, with respect to Realized Losses and Additional Trust Fund
Expenses allocated to the Class D Certificates, such corresponding distribution
shall be deemed to be a distribution with respect to REMIC I Regular Interest
LD-1, REMIC I Regular Interest LD-2 and REMIC I Regular Interest LD-3 allocated
pro rata based upon their respective REMIC I Principal Balances; provided,
further, with respect to Realized Losses and Additional Trust Fund Expenses
allocated to the Class G Certificates, such corresponding distribution shall be

Losses and Additional Trust Fund Expenses allocated to the Class J Certificates,
such corresponding distribution shall be deemed to be a distribution with
respect to REMIC I Regular Interest LJ-1 and REMIC I Regular Interest LJ-2
allocated pro rata based upon their respective REMIC I Principal Balances. Any
amounts remaining in the Distribution Account in respect of REMIC I after the
deemed distributions in respect of the REMIC I Regular Interests shall (except
as otherwise provided in Section 9.01) be distributed by the Trustee to the
Holders of the Class R-I Certificates.

     (i) Reserved.

     (j) On each Distribution Date, the Trustee shall withdraw amounts from the
Gain-on-Sale Reserve Account and shall distribute such amounts to reimburse the
Holders of the Regular Certificates (in order of alphabetical Class designation)
up to an amount equal to all Realized Losses, if any, previously deemed
allocated to them and unreimbursed after application of the Available
Distribution Amount for such Distribution Date. Amounts paid from the
Gain-on-Sale Reserve Account will not reduce the Certificate Principal Balances
of the Classes receiving such distributions. Any amounts in the Gain-on-Sale
Reserve Account with respect to the 77 West Wacker Drive Mortgage Loan shall be
applied to reimburse for previously allocated Realized Losses first, in respect
of the Certificates that represent the 77 West Wacker Drive Pooled Portion and
second, in respect of the 77 West Wacker Drive Non-Pooled Portion. Any amounts
remaining in the Gain-on-Sale Reserve Account after such distributions shall be
applied to offset future Realized Losses and upon termination of the Trust Fund,
any amounts remaining in the Gain-on-Sale Reserve Account shall be distributed
to the Class R-I Certificateholders.

     (k) For so long as (i) no monetary or material non-monetary event of
default has occurred and is continuing with respect to the 77 West Wacker Drive
Mortgage Loan and (ii) there are no unreimbursed Advances with respect to the 77
West Wacker Drive Mortgage Loan outstanding as of the subject Distribution Date,
on each Distribution Date, the Trustee shall

the Master Servicer and the Special Servicer, withdraw (1) amounts on deposit in
the 77 West Wacker Drive Distribution Account, after payment of amounts payable
from the 77 West Wacker Drive Distribution Account in accordance with Section
3.05(f)(ii) through (viii) and (2) amounts on deposit in the Distribution
Account, to the extent of the 77 West Wacker Drive Available Distribution

     zero) by any payments or other collections of principal of the 77 West
     Wacker Drive Mortgage Loan applied to reimburse Nonrecoverable Advances and
     Workout-Delayed Reimbursement Amounts with respect to other Mortgage Loans
     and REO Loans) equal to the product of (x) the 77 West Wacker Drive

Expenses in respect of or allocable to the 77 West Wacker Drive Mortgage Loan or

on such Distribution Date pursuant to either clauses (v), (viii) and (xi) of the
77 West Wacker Drive Non-Default Distribution Priority or clauses (v), (viii)
and (xi) of the 77WestWacker Drive Default Distribution Priority, as applicable,

with respect to any Mortgagor and the failure of the Trustee, Master Servicer or
the Special Servicer to disseminate information for such reason shall not be a
breach hereof.

     (b) In the performance of its obligations set forth in Section 4.05 and its
other duties hereunder, the Trustee may conclusively rely on reports provided to
it by the Master Servicer, and the Trustee shall not be responsible to
recompute, recalculate or verify the information provided to it by the Master
Servicer.

     Section 4.03   P&I Advances; Reimbursement of P&I Advances and Servicing
Advances.

     (a) On or before 2:00 p.m., New York City time, on each P&I Advance Date,
the Master Servicer shall (i) apply amounts in the Certificate Account received
after the end of the related Collection Period or otherwise held for future
distribution to Certificateholders in subsequent months in discharge of its
obligation to make P&I Advances or (ii) subject to Section 4.03(c) below, remit
from its own funds to the Trustee for deposit into the Distribution Account (or
the 77 West Wacker Drive Distribution Account in the case of the 77 West Wacker
Drive Non-Pooled Portion) an amount equal to the aggregate amount of P&I
Advances, if any, to be made in respect of the related Distribution Date. The
Master Servicer may also make P&I Advances in the form of any combination of
clauses (i) and (ii) above aggregating the total amount of P&I Advances to be
made. Any amounts held in the Certificate Account for future distribution and so
used to make P&I Advances shall be appropriately reflected in the Master
Servicer's records and replaced by the Master Servicer by deposit in the
Certificate Account on or before the next succeeding Determination Date (to the
extent not previously replaced through the deposit of Late Collections of the
delinquent principal and interest in respect of which such P&I Advances were
made). If, as of 3:00 p.m., New York City time, on any P&I Advance Date, the
Master Servicer shall not have made any P&I Advance required to be made on such
date pursuant to this Section 4.03(a) (and shall not have delivered to the
Trustee the requisite Officer's Certificate and documentation related to a
determination of nonrecoverability of a P&I Advance), then the Trustee shall
provide notice of such failure to a Servicing Officer of the

                                      213
<PAGE>

Master Servicer by facsimile transmission sent to the facsimile number set forth
in Section 11.05 (or such alternative number provided by the Master Servicer to
the Trustee in writing) as soon as possible, but in any event before 4:00 p.m.,
New York City time, on such P&I Advance Date. If the Trustee does not receive
the full amount of such P&I Advances by 10:00 a.m., New York City time, on the
related Distribution Date, then, subject to Section 4.03(c), (i) the Trustee
shall, no later than 11:00 a.m., or the Fiscal Agent no later than 1:00 p.m.,
New York City time, on such related Distribution Date make the portion of such
P&I Advances that was required to be, but was not, made by the Master Servicer
on such P&I Advance Date, and (ii) the provisions of Sections 7.01 and 7.02
shall apply.

     (b) The aggregate amount of P&I Advances to be made by the Master Servicer,
the Trustee or the Fiscal Agent in respect of any Distribution Date shall,
subject to Section 4.03(c) below, equal the aggregate of all Periodic Payments
(other than Balloon Payments) and any Assumed Scheduled Payments, net of related
Servicing Fees, in respect of the Mortgage Loans (including, without limitation,
Balloon Mortgage Loans delinquent as to their respective Balloon Payments) and
any REO Loans on their respective Due Dates during the related Collection
Period, in each case to the extent such amount was not paid by or on behalf of
the related Mortgagor or otherwise collected (including as net income from REO
Properties) as of the close of business on the related Determination Date;
provided, that, (x) if the Periodic Payment on any Mortgage Loan has been
reduced in connection with a bankruptcy or similar proceeding involving the
related Mortgagor or a modification, waiver or amendment granted or agreed to by
the Special Servicer pursuant to Section 3.20, or if the final maturity on any
Mortgage Loan shall be extended in connection with a bankruptcy or similar
proceeding involving the related Mortgagor or a modification, waiver or
amendment granted or agreed to by the Special Servicer pursuant to Section 3.20,
and the Periodic Payment due and owing during the extension period is less than
the related Assumed Scheduled Payment, then the Master Servicer, the Trustee or
the Fiscal Agent shall, as to such Mortgage Loan only, advance only the amount
of the Periodic Payment due and owing after taking into account such reduction
(net of related Servicing Fees) in the event of subsequent delinquencies
thereon; and (y) if it is determined that an Appraisal Reduction Amount exists
with respect to any Required Appraisal Loan, then, with respect to the
Distribution Date immediately following the date of such determination and with
respect to each subsequent Distribution Date for so long as such Appraisal
Reduction Amount exists with respect to such Required Appraisal Loan, the Master
Servicer, the Trustee or the Fiscal Agent will be required in the event of
subsequent delinquencies to advance in respect of such Mortgage Loan only an
amount equal to the sum of (A) the interest portion of the P&I Advance required
to be made equal to the product of (x) the amount of the interest portion of the
P&I Advance for that Mortgage Loan for the related Distribution Date without
regard to this sentence, and (y) a fraction, expressed as a percentage, the
numerator of which is equal to the Stated Principal Balance of that Mortgage
Loan immediately prior to the related Distribution Date, net of the related
Appraisal Reduction Amount, if any, and the denominator of which is equal to the
Stated Principal Balance of that Mortgage Loan immediately prior to the related
Distribution Date and (B) the amount of the principal portion of the P&I Advance
that would otherwise be required without regard to this clause (y).

     (c) Notwithstanding anything herein to the contrary, no P&I Advance shall
be required to be made hereunder if such P&I Advance would, if made, constitute
a Nonrecoverable

                                      214
<PAGE>

P&I Advance. The determination by the Master Servicer that a prior P&I Advance
(or Unliquidated Advance in respect thereof) that it has made constitutes a
Nonrecoverable P&I Advance or that any proposed P&I Advance, if made, would
constitute a Nonrecoverable P&I Advance, shall be evidenced by an Officers'
Certificate delivered to the Trustee, the Fiscal Agent and the Depositor on or
before the related P&I Advance Date, setting forth the basis for such
determination, together with any other information, including Appraisals (the
cost of which may be paid out of the Certificate Account pursuant to Section
3.05(a)) (or, if no such Appraisal has been performed pursuant to this Section
4.03(c), a copy of an Appraisal of the related Mortgaged Property performed
within the twelve months preceding such determination), related Mortgagor
operating statements and financial statements, budgets and rent rolls of the
related Mortgaged Properties, engineers' reports, environmental surveys and any
similar reports that the Master Servicer may have obtained consistent with the
Servicing Standard and at the expense of the Trust Fund, that support such
determination by the Master Servicer. On the fourth Business Day before each
Distribution Date, the Special Servicer shall report to the Master Servicer the
Special Servicer's determination as to whether each P&I Advance made with
respect to any previous Distribution Date or required to be made with respect to
such Distribution Date with respect to any Specially Serviced Mortgage Loan or
REO Loan is a Nonrecoverable P&I Advance. The Master Servicer shall be entitled
to conclusively rely on such determination. The Trustee and the Fiscal Agent
shall be entitled to rely, conclusively, on any determination by the Master
Servicer that a P&I Advance, if made, would be a Nonrecoverable Advance (and
with respect to a P&I Advance, the Trustee and the Fiscal Agent, as applicable,
shall rely on the Master Servicer's determination that the P&I Advance would be
a Nonrecoverable Advance if the Trustee or the Fiscal Agent determines that it
does not have sufficient time to make such determination); provided, however,
that if the Master Servicer has failed to make a P&I Advance for reasons other
than a determination by the Master Servicer that such P&I Advance would be a
Nonrecoverable Advance, the Trustee or the Fiscal Agent shall make such Advance
within the time periods required by Section 4.03(a) unless the Trustee or the
Fiscal Agent, as the case may be, in good faith, makes a determination prior to
the times specified in Section 4.03(a) that such P&I Advance would be a
Nonrecoverable Advance. The Trustee in determining whether or not a P&I Advance
previously made is, or a proposed P&I Advance, if made, would be, a
Nonrecoverable Advance shall be subject to the standards applicable to the
Master Servicer hereunder.

     From and after the date, if any, on which the Master Servicer has received
notice to the effect that the Fairfield Commons Pari Passu Companion Loan has
been securitized as part of a rated commercial mortgage securitization similar
to the commercial mortgage securitization effected by this Agreement, (i) if the
Master Servicer receives written notice (upon which the Master Servicer may
conclusively rely) (which notice is accompanied by the supporting evidence for
such determination) that the primary party responsible for making debt service
advances similar to P&I Advances with respect to such other commercial mortgage
securitization has determined, pursuant to the related securitization agreement,
that any such debt service advance made or to be made with respect to the
Fairfield Commons Pari Passu Companion Loan (or any successor REO Loan with
respect thereto) would not ultimately be recoverable out of collections on such
mortgage loan (or the related REO Loan), then the Master Servicer shall deliver
an Officer's Certificate to such effect to the Trustee, the Fiscal Agent, the
Special Servicer and the Depositor, and any P&I Advance made or proposed to be
made with respect to the Fairfield Commons Pooled Mortgage Loan shall thereafter
be deemed to be a Nonrecoverable P&I

                                      215
<PAGE>

Advance; (ii) if the Master Servicer thereafter receives notice (which notice is
accompanied by the supporting evidence for such determination) that such
determination has been withdrawn or rescinded by such primary party, and P&I
Advances in respect of the Fairfield Commons Pooled Mortgage Loan to which are
thereupon no longer deemed to constitute Nonrecoverable P&I Advances by
operation of the definition of "Nonrecoverable P&I Advance" herein, then the
Master Servicer shall provide notice to such effect to the Trustee, the Fiscal
Agent, the Special Servicer and the Depositor; (iii) if the Master Servicer
determines that any P&I Advance made or to be made with respect to the Fairfield
Commons Pooled Mortgage Loan (or any successor REO Loan with respect thereto) is
or, if made, would be a Nonrecoverable P&I Advance, then the Master Servicer
shall notify in writing such primary party under such other commercial mortgage
securitization of such determination (which notice shall be accompanied by the
supporting evidence for such determination as contemplated by the preceding
paragraph); and (iv) following any determination described in the preceding
clause (iii), if the Master Servicer subsequently determines (other than by
operation of clause (ii) above) that P&I Advances made or to be made with
respect to the Fairfield Commons Pooled Mortgage Loan (or any successor REO Loan
with respect thereto) are no longer Nonrecoverable P&I Advances, then the Master
Servicer shall notify in writing such primary party under such other commercial
mortgage securitization of such determination (which notice shall be accompanied
by the supporting evidence for such determination as contemplated by the
preceding paragraph). The holder of the Fairfield Commons Pari Passu Companion
Loan (and its respective primary party responsible for making debt service
advances similar to P&I Advances under such other commercial mortgage
securitization) shall be a third party beneficiary of the preceding clause (iii)
to the extent that such clause relates to the Fairfield Commons Pari Passu
Companion Loan and the Trust Fund or the Master Servicer is a third party
beneficiary of a provision in the Fairfield Commons Intercreditor Agreement or
in the pooling and servicing or trust and servicing agreement governing the
other commercial mortgage securitization that imposes (in connection with the
Fairfield Commons Pari Passu Companion Loan) on the primary party thereunder
responsible for making debt service advances similar to P&I Advances duties
(among others) that are substantially the same as the duties that are imposed
(in connection with the Fairfield Commons Pooled Mortgage Loan) on the Master
Servicer.

     (d) In connection with the recovery by the Master Servicer, the Trustee or
the Fiscal Agent of any P&I Advance out of the Certificate Account pursuant to
Section 3.05(a), subject to the next sentence, the Master Servicer shall be
entitled to pay itself, the Trustee or the Fiscal Agent, as the case may be, out
of any amounts then on deposit in the Certificate Account, interest at the
Reimbursement Rate (or, with respect to the AB Mortgage Loans and related
Companion Loans, the rate provided in the related Intercreditor Agreement if a
rate is provided therein) in effect from time to time, accrued on the amount of
such P&I Advance (to the extent made with its own funds) from the date made to
but not including the date of reimbursement, such interest to be payable first,
subject to the terms of the related Intercreditor Agreement with respect to any
Loan Pair, out of late payment charges and Penalty Interest received on the
related Mortgage Loan or REO Property during the Collection Period in which such
reimbursement is made and subject to the terms of the related Intercreditor
Agreement with respect to any Loan Pair, then from general collections on the
Mortgage Loans then on deposit in the Certificate Account; provided, however,
that no interest shall accrue on any P&I Advance made with respect to a Mortgage
Loan if the related Periodic Payment is received on or prior to the Due Date of
such Mortgage Loan, prior to the expiration of any applicable grace period or
prior to the

                                      216
<PAGE>

related P&I Advance Date. To the extent the Master Servicer receives late
payment charges or Penalty Interest on a Mortgage Loan for which interest on
Advances related to such Mortgage Loan has been paid from general collections on
deposit in the Certificate Account and not previously reimbursed, the Master
Servicer shall deposit in the Certificate Account, on or prior to the P&I
Advance Date following the collection of such late payment charges or Penalty
Interest, an amount equal to the lesser of (i) the amount of late payment
charges or Penalty Interest received on such Mortgage Loan or (ii) the amount of
interest paid to the Master Servicer on the related P&I Advance for such
Mortgage Loan for which the Trust Fund has not been previously reimbursed. The
Master Servicer shall reimburse itself, the Trustee or the Fiscal Agent, as
applicable, for any outstanding P&I Advance made thereby as soon as practicable
after funds available for such purpose have been received by the Master
Servicer, and in no event shall interest accrue in accordance with this Section
4.03(d) on any P&I Advance as to which the corresponding Late Collection, or as
to which any Periodic Payment in respect of any Mortgage Loan, the Due Date of
which is on the tenth day of a calendar month, was received by the Master
Servicer on or prior to the related P&I Advance Date.

     (e) In no event shall the Master Servicer, the Trustee or the Fiscal Agent
make a P&I Advance with respect to any Companion Loan.

     (f) Upon the determination that a previously made Advance is a
Nonrecoverable Advance, to the extent that the reimbursement thereof would
exceed the full amount of the principal portion of general collections deposited
in the Certificate Account, the Master Servicer, the Trustee or the Fiscal
Agent, as applicable, at its own option, instead of obtaining reimbursement for
the remaining amount of such Nonrecoverable Advance pursuant to Section
3.05(a)(vii) immediately, may elect to refrain from obtaining such reimbursement
for such portion of the Nonrecoverable Advance during the one-month collection
period ending on the then-current Determination Date. If the Master Servicer (or
the Trustee or the Fiscal Agent) makes such an election at its sole option to
defer reimbursement with respect to all or a portion of a Nonrecoverable Advance
(together with interest thereon), then such Nonrecoverable Advance (together
with interest thereon) or portion thereof shall continue to be fully
reimbursable in the subsequent Collection Period (subject, again, to the same
sole option to defer; it is acknowledged that, in such a subsequent period, such
Nonrecoverable Advance shall again be payable first from principal collections
as described above prior to payment from other collections). In connection with
a potential election by the Master Servicer (or the Trustee or the Fiscal Agent)
to refrain from the reimbursement of a particular Nonrecoverable Advance or
portion thereof during the one-month Collection Period ending on the related
Determination Date for any Distribution Date, the Master Servicer (or the
Trustee or the Fiscal Agent) shall further be authorized to wait for principal
collections to be received before making its determination of whether to refrain
from the reimbursement of a particular Nonrecoverable Advance or portion
thereof) until the end of such Collection Period. The foregoing shall not,
however, be construed to limit any liability that may otherwise be imposed on
such Person for any failure by such Person to comply with the conditions to
making such an election under this subsection or to comply with the terms of
this subsection and the other provisions of this Agreement that apply once such
an election, if any, has been made. Any election by the Master Servicer (or the
Trustee or the Fiscal Agent) to refrain from reimbursing itself for any
Nonrecoverable Advance (together with interest thereon) or portion thereof with
respect to any Collection Period shall not be construed to impose on the Master
Servicer (or the Trustee or the Fiscal Agent) any obligation

                                      217
<PAGE>

to make such an election (or any entitlement in favor of any Certificateholder
or any other Person to such an election) with respect to any subsequent
Collection Period or to constitute a waiver or limitation on the right of the
Master Servicer (or the Trustee or the Fiscal Agent) to otherwise be reimbursed
for such Nonrecoverable Advance (together with interest thereon). Any such
election by the Master Servicer, the Trustee or the Fiscal Agent shall not be
construed to impose any duty on the other such party to make such an election
(or any entitlement in favor of any Certificateholder or any other Person to
such an election). Any such election by any such party to refrain from
reimbursing itself or obtaining reimbursement for any Nonrecoverable Advance or
portion thereof with respect to any one or more Collection Periods shall not
limit the accrual of interest on such Nonrecoverable Advance for the period
prior to the actual reimbursement of such Nonrecoverable Advance. None of the
Master Servicer, the Trustee, the Fiscal Agent or the other parties to this
Agreement shall have any liability to one another or to any of the
Certificateholders or any of the Companion Holders for any such election that
such party makes as contemplated by this subsection or for any losses, damages
or other adverse economic or other effects that may arise from such an election,
and shall not constitute a violation of the Servicing Standard and/or with
respect to the Trustee or the Fiscal Agent, constitute a violation of any
fiduciary duty to the Certificateholders or contractual duty under this
Agreement. Nothing herein shall give the Master Servicer, the Trustee or the
Fiscal Agent the right to defer reimbursement of a Nonrecoverable Advance to the
extent that principal collections then available in the Certificate Account are
sufficient to reimburse such Nonrecoverable Advances pursuant to Section
3.05(a)(vii).

     SECTION 4.04   Allocation of Realized Losses and Additional Trust Fund
Expenses; Allocation of Certificate Deferred Interest; Allocation of Appraisal
Reduction Amounts.

     (a) On each Distribution Date, following all distributions to be made on
such date pursuant to Section 4.01, subject to Section 4.04(e), the Trustee
shall allocate to the respective Classes of Sequential Pay Certificates as
follows the aggregate of all Realized Losses and Additional Trust Fund Expenses
that were incurred at any time following the Cut-off Date through the end of the
related Collection Period and in any event that were not previously allocated
pursuant to this Section 4.04(a) on any prior Distribution Date, but only to the
extent that (i) the aggregate Certificate Principal Balance of the Sequential
Pay Certificates as of such Distribution Date (after taking into account all of
the distributions made on such Distribution Date pursuant to Section 4.01),
exceeds (ii) the aggregate Stated Principal Balance (for purposes of this
calculation only, not giving effect to any reductions of the Stated Principal
Balance for payments of principal collected on the Mortgage Loans that were used
to reimburse any Workout-Delayed Reimbursement Amounts pursuant to Section
3.05(a)(vii) to the extent such Workout-Delayed Reimbursement Amounts are not
otherwise determined to be Nonrecoverable Advances, are not paid by the related
Mortgagor and do not constitute an Unliquidated Advance related to a liquidated
Mortgage Loan) of the Mortgage Pool that will be outstanding immediately
following such Distribution Date: first, to the Class Q Certificates, until the
remaining Class Principal Balance thereof has been reduced to zero; second, to
the Class P Certificates, until the remaining Class Principal Balance thereof
has been reduced to zero; third, to the Class N Certificates, until the
remaining Class Principal Balance thereof has been reduced to zero; fourth, to
the Class M Certificates, until the remaining Class Principal Balance thereof
has been reduced to zero; fifth to the Class L Certificates, until the remaining
Class Principal

                                      218
<PAGE>

Balance thereof has been reduced to zero; sixth, to the Class K Certificates,
until the remaining Class Principal Balance thereof has been reduced to zero;
seventh, to the Class J Certificates, until the remaining Class Principal
Balance thereof has been reduced to zero; eighth, to the Class H Certificates,
until the remaining Class Principal Balance thereof has been reduced to zero;
ninth, to the Class G Certificates, until the remaining Class Principal Balance
thereof has been reduced to zero; tenth, to the Class F Certificates, until the
remaining Class Principal Balance thereof has been reduced to zero; eleventh, to
the Class E Certificates, until the remaining Class Principal Balance thereof
has been reduced to zero; twelfth, to the Class D Certificates, until the
remaining Class Principal Balance thereof has been reduced to zero; thirteenth,
to the Class C Certificates, until the remaining Class Principal Balance thereof
has been reduced to zero; fourteenth, to the Class B Certificates, until the
remaining Class Principal Balance thereof has been reduced to zero; and
fifteenth, pro rata (based on remaining Class Principal Balances) to the Class
A-1 Certificates, Class A-2 Certificates, Class A-3 Certificates, Class A-4
Certificates and Class A-1A Certificates until the Class Principal Balances
thereof are reduced to zero. Any allocation of Realized Losses and Additional
Trust Fund Expenses to a Class of Sequential Pay Certificates shall be made by
reducing the Class Principal Balance thereof by the amount so allocated. All
Realized Losses and Additional Trust Fund Expenses, if any, allocated to a Class
of Sequential Pay Certificates shall be allocated among the respective
Certificates of such Class in proportion to the Percentage Interests evidenced
thereby. All Realized Losses and Additional Trust Fund Expenses, if any, that
have not been allocated to the Regular Certificates as of the Distribution Date
on which the aggregate Certificate Principal Balance of such Regular
Certificates has been reduced to zero, shall be deemed allocated to the Residual
Certificates.

     If and to the extent any Nonrecoverable Advances (plus interest thereon)
that were reimbursed from principal collections on the Mortgage Loans and
previously resulted in a reduction of the Principal Distribution Amount are
subsequently recovered on the related Mortgage Loan, then, on the Distribution
Date immediately following the Collection Period in which such recovery occurs,
the amount of such recovery shall be added to the Class Principal Balance of the
Class or Classes of Sequential Pay Certificates that previously were allocated
Realized Losses and/or Additional Trust Fund Expenses, in sequential order
(commencing with the most senior Class of Sequential Pay Certificates that
experienced such an allocation of Realized Losses and/or Additional Trust Fund
Expenses), in each case up to the amount of the unreimbursed Realized Losses
and/or Additional Trust Fund Expenses allocated to such Class. If the Class
Principal Balance of any Class is so increased, the amount of unreimbursed
Realized Losses and/or Additional Trust Fund Expenses of such Class shall be
decreased by such amount.

     To the extent the Class Principal Balance of a Class of Sequential Pay
Certificates is increased pursuant to the second paragraph of this Section
4.04(a), the REMIC I Principal Balances of the Corresponding REMIC I Regular
Interest(s) shall also be so increased; provided that with respect to the
application of such additions to the REMIC I Principal Balances of REMIC I
Regular Interests LA-1-1 and LA-1-2, such additions shall be allocated first, to
REMIC I Regular Interest LA-1-2 up to the amount of the unreimbursed Realized
Losses and/or Additional Trust Fund Expenses previously allocated to it and then
to REMIC Regular Interest LA-1-1; provided, further, that with respect to the
application of any such additions to the REMIC I Principal Balances of REMIC I
Regular Interests LA-2-1, LA-2-2 and LA-2-3, such additions shall be allocated,
first, to REMIC I Regular Interest LA-2-3 up to the amount of the unreimbursed
Realized Losses and/or Additional Trust Fund Expenses previously allocated to it
and then to REMIC I Regular Interest LA-2-2 up to the amount of the unreimbursed
Realized Losses and/or Additional Trust Fund Expenses previously allocated to it
and then to REMIC I Regular Interest LA-2-1; provided, further, that with
respect to the application of such additions to the REMIC I Principal Balances
of REMIC I Regular Interests LA-3-1, LA-3-2, LA-3-3 and LA-3-4, such additions
shall be allocated first, to REMIC I Regular Interest LA-3-4 up to the amount of
the unreimbursed Realized Losses and/or Additional Trust Fund Expenses
previously allocated to it and then to REMIC I Regular Interest LA-3-3 up to the
amount of the unreimbursed Realized Losses and/or Additional Trust Fund Expenses
previously allocated to it and then to REMIC I Regular Interest

                                      219
<PAGE>

LA-3-2 up to the amount of the unreimbursed Realized Losses and/or Additional
Trust Fund Expenses previously allocated to it and then to REMIC I Regular
Interest LA-3-1; provided, further, that with respect to the application of any
such additions to the REMIC I Principal Balances of REMIC I Regular Interests
LA-4-1 and LA-4-2, such additions shall be allocated first, to REMIC I Regular
Interest LA-4-2 up to the amount of the unreimbursed Realized Losses and/or
Additional Trust Fund Expenses previously allocated to it and then to REMIC I
Regular Interest LA-4-1; provided, further, that with respect to the application
of any such additions to the REMIC I Principal Balances of REMIC I Regular
Interests LA-1A-1, LA-1A-2, LA-1A-3, LA-1A-4, LA-1A-5, LA-1A-6, LA-1A-7 and
LA-1A-8, such additions shall be allocated first, to REMIC I Regular Interest
LA-1A-8 up to the amount of the unreimbursed Realized Losses and/or Additional
Trust Fund Expenses previously allocated to it and then to REMIC I Regular
Interest LA-1A-7 up to the amount of the unreimbursed Realized Losses and/or
Additional Trust Fund Expenses previously allocated to it and then to REMIC I

to REMIC I Regular Interest LA-1A-4 up to the amount of the unreimbursed
Realized Losses and/or Additional Trust Fund Expenses previously allocated to it
and then to REMIC I Regular Interest LA-1A-3 up to the amount of the
unreimbursed Realized Losses and/or Additional Trust Fund Expenses previously
allocated to it and then to REMIC I Regular Interest LA-1A-2 up to the amount of
the unreimbursed Realized Losses and/or Additional Trust Fund Expenses
previously allocated to it and then to REMIC I Regular Interest LA-1A-1;
provided, further, that with respect to the application of such additions to the
REMIC I Principal Balances of REMIC I Regular Interests LD-1, LD-2 and LD-3,
such additions shall be allocated first, to REMIC I Regular Interest LD-3 up to
the amount of the unreimbursed Realized Losses and/or Additional Trust Fund
Expenses previously allocated to it and then to REMIC I Regular Interest LD-2 up
to the amount of the unreimbursed Realized Losses and/or Additional Trust Fund
Expenses previously allocated to it and then to REMIC I Regular Interest LD-1;
provided, further, that with respect to the application of any such additions to
the REMIC I Principal Balances of REMIC I Regular Interests LG-1 and LG-2, such
additions shall be allocated first, to REMIC I Regular Interest LG-2 up to the
amount of the unreimbursed Realized Losses and/or Additional Trust Fund Expenses
previously allocated to it and then to REMIC I Regular Interest LG-1; provided,
further, that with respect to the application of such additions to the REMIC I
Principal Balances of REMIC I

                                      220
<PAGE>

Regular Interests LJ-1 and LJ-2 any such additions shall be allocated first, to
REMIC I Regular Interest LJ-2 up to the amount of the unreimbursed Realized
Losses and/or Additional Trust Fund Expenses previously allocated to it and then
to Regular Interest REMIC I Regular Interest LJ-1. If the REMIC I Principal
Balance of any REMIC I Regular Interest is so increased, the amount of
unreimbursed Realized Losses and/or Additional Trust Fund Expenses of such REMIC
I Regular Interest shall be decreased by such amount.

     (b) On each Distribution Date, following the deemed distributions to be
made in respect of the REMIC I Regular Interests pursuant to Section 4.01(h) and
subject to Section 4.04(e), the REMIC I Principal Balance(s) of the
Corresponding REMIC I Regular Interest(s) for each Class of Sequential Pay
Certificates (after taking account of such deemed distributions) shall be
reduced as a result of Realized Losses and Additional Trust Fund Expenses to
equal the Class Principal Balance of such Class of Sequential Pay Certificates
that will be outstanding immediately following such Distribution Date; provided,
that with respect to the application of reductions of the REMIC I Principal
Balances of REMIC I Regular Interests LA-1-1 and LA-1-2 to the Class Principal
Balance of the Class A-1 Certificates that will be outstanding immediately
following such Distribution Date, each such reduction shall be allocated to
REMIC I Regular Interest LA-1-1 until its REMIC I Principal Balance is reduced
to zero, and then to REMIC Regular Interest LA-1-2; provided, further, that with
respect to the application of reductions of the REMIC I Principal Balances of
REMIC I Regular Interests LA-2-1, LA-2-2 and LA-2-3 to the Class Principal
Balance of the Class A-2 Certificates that will be outstanding immediately
following such Distribution Date, each such reduction shall be allocated to
REMIC I Regular Interest LA-2-1 until its REMIC I Principal Balance is reduced
to zero and then to REMIC I Regular Interest LA-2-2 until its REMIC I Principal

reduction shall be allocated to REMIC I Regular Interest LA-3-1 until its REMIC
I Principal Balance is reduced to zero and then to REMIC I Regular Interest
LA-3-2 until its REMIC I Principal Balance is reduced to zero and then to REMIC
I Regular Interest LA-3-3 until its REMIC I Principal Balance is reduced to zero
and then to REMIC I Regular Interest LA-3-4; provided, further, that with
respect to the application of reductions of the REMIC I Principal Balances of
REMIC I Regular Interests LA-4-1 and LA-4-2 to the Class Principal Balance of
the Class A-4 Certificates that will be outstanding immediately following such
Distribution Date, each such reduction shall be allocated to REMIC I Regular
Interest LA-4-1 until its REMIC I Principal Balance is reduced to zero and then
to REMIC I Regular Interest LA-4-2; provided, further, that with respect to the
application of reductions of the REMIC I Principal Balances of REMIC I Regular
Interests LA-1A-1, LA-1A-2, LA-1A-3, LA-1A-4, LA-1A-5, LA-1A-6, LA-1A-7 and
LA-1A-8 to the Class Principal Balance of the Class A-1A Certificates that will
be outstanding immediately following such Distribution Date, each such reduction
shall be allocated to REMIC I Regular Interest LA-1A-1 until its REMIC I
Principal Balance is reduced to zero and then to REMIC I Regular Interest
LA-1A-2 until its REMIC I Principal Balance is reduced to zero and then to REMIC
I Regular Interest LA-1A-3 until its REMIC I Principal Balance is reduced to
zero and then to REMIC I Regular Interest LA-1A-4 until its REMIC I Principal
Balance is reduced to zero and then to REMIC I Regular Interest LA-1A-5 until

Interest LA-1A-6 until its REMIC I Principal Balance is reduced to zero and then
to REMIC I Regular Interest LA-1A-7 until its REMIC I Principal Balance is
reduced to zero and then to REMIC I Regular Interest LA-1A-8; provided, further,
that with respect to the application of reductions of the aggregate REMIC I
Principal Balances of REMIC I Regular Interests LD-1, LD-2 and LD-3 to the Class
Principal Balance of the Class D Certificates that will be outstanding
immediately following such Distribution Date, each such reduction shall be
allocated to REMIC I Regular Interest LD-1 until its REMIC I Principal Balance
is reduced to zero and then to REMIC I Regular Interest LD-2 until its REMIC I
Principal Balance is reduced to zero and then to REMIC I Regular Interest LD-3;
provided, further, that with respect to the application of reductions of the
aggregate REMIC I Principal Balances of REMIC I Regular Interests LG-1 and LG-2
to the Class Principal Balance of the Class G Certificates that will be
outstanding immediately following such Distribution Date, each such reduction
shall be allocated to REMIC I Regular Interest LG-1 until its REMIC I Principal
Balance is reduced to zero and then to REMIC I Regular Interest LG-2; provided,
further, that with respect to the application of reductions of the aggregate
REMIC I Principal Balances of REMIC I Regular Interests LJ-1 and LJ-2 to the
Class Principal Balance of the Class J Certificates that will be outstanding
immediately following such Distribution Date, each such reduction shall be
allocated to REMIC I Regular Interest LJ-1 until its REMIC I Principal Balance
is reduced to zero and then to REMIC I Regular Interest LJ-2.

     (c) On any Distribution Date, subject to Section 4.04(e), the amount of any
Mortgage Deferred Interest not otherwise allocated to the Class WW Principal
Balance Certificates will be allocated as Certificate Deferred Interest to each
outstanding Class of Sequential Pay Certificates in reverse alphabetical order
(except with respect to the Class A-1, Class A-2, Class A-3, Class A-4
Certificates and Class A-1A Certificates, which amounts shall be applied pro
rata (based on remaining Class Principal Balances) to such Certificates), in
each case up to the respective Accrued Certificate Interest for each such Class
of Certificates for such Distribution Date. On each such Distribution Date, the
Class Principal Balance of each Class of Certificates to which Certificate
Deferred Interest has been allocated will be increased by the amount of
Certificate Deferred Interest allocated to such Class. The amount of Certificate
Deferred Interest allocated to any Class of Sequential Pay Certificates will be
allocated to, and will increase the REMIC I Principal Balances of the
Corresponding REMIC I Regular Interests; provided, however, allocations to REMIC
I Regular Interests LA-1-1 and LA-1-2 shall be applied pro rata based upon their
respective REMIC I Principal Balances, provided, further, that allocations to
REMIC I Regular Interests LA-2-1, LA-2-2 and LA-2-3 shall be applied pro rata
based upon their respective REMIC I Principal Balances, provided, further, that
allocations to REMIC I Regular Interests LA-3-1, LA-3-2, LA-3-3 and LA-3-4 shall
be applied pro rata based upon their respective REMIC I Principal Balances,
provided, further, that allocations to REMIC I Regular Interests LA-4-1 and
LA-4-2 shall be applied pro rata based upon their respective REMIC I Principal
Balances, provided, further, that allocations to REMIC I Regular Interests
LA-1A-1, LA-1A-2, LA-1A-3, LA-1A-4, LA-1A-5, LA-1A-6, LA-1A-7 and LA-1A-8, shall
be applied pro rata based upon their respective REMIC I Principal Balances
provided, further, that allocations to REMIC I Regular Interests LD- 1, LD-2 and
LD-3 shall be applied pro rata based upon their respective REMIC I Principal
Balances, provided, further, that allocations to REMIC I Regular Interests LG-1
and LG-2 shall be applied pro rata based upon their respective REMIC I Principal
Balances, and provided, further, that allocations to REMIC I Regular Interests
LJ-1 and

                                      222
<PAGE>

LJ-2 shall be applied pro rata based upon their respective REMIC I Principal
Balances, in each case up to the Pass-Through Rate of the Corresponding
Certificates.

     (d) The Master Servicer shall report to the Trustee on or before each
Determination Date all Appraisal Reduction Amounts and the Trustee shall report
to the Master Servicer no later than 10:00 a.m. on the related P&I Advance Date
the Pass-Through Rates necessary to calculate the allocation required by this
Section 4.04(d).

     (e) On each Distribution Date, following all distributions to be made on
such date pursuant to Section 4.01, the Trustee shall, prior to their allocation
to any Class of Sequential Pay Certificates, allocate to the respective Classes
of Class WW Principal Balance Certificates as follows the aggregate of all
Realized Losses and Additional Trust Fund Expenses with respect to the 77 West
Wacker Drive Mortgage Loan and its pro rata share of Additional Trust Fund
Expenses not attributable to any particular Mortgage Loan that were incurred at
any time following the Cut-off Date through the end of the related Collection
Period and in any event that were not previously allocated pursuant to this
Section 4.04(e) on any prior Distribution Date, but only to the extent that (i)
the aggregate Certificate Principal Balance of the such Class WW Principal
Balance Certificates as of such Distribution Date (after taking into account all
of the distributions made on such Distribution Date pursuant to Section 4.01),
exceeds (ii) the aggregate Stated Principal Balance of the 77 West Wacker Drive
Non-Pooled Portion that will be outstanding immediately following such
Distribution Date: first, to the Class WW-3 Certificates, until the remaining
Class Principal Balance thereof has been reduced to zero; second, to the Class
WW-2 Certificates, until the remaining Class Principal Balance thereof has been
reduced to zero; and third, to the Class WW-1 Certificates, until the remaining
Class Principal Balance thereof has been reduced to zero. Any allocation of
Realized Losses and Additional Trust Fund Expenses to a Class of Class WW
Principal Balance Certificates shall be made by reducing the Class Principal
Balance thereof by the amount so allocated. All Realized Losses and Additional
Trust Fund Expenses, if any, allocated to a Class of Class WW Principal Balance
Certificates shall be allocated among the respective Certificates of such Class
in proportion to the Percentage Interests evidenced thereby.

     On each Distribution Date, following the deemed distributions to be made in
respect of the REMIC I Regular Interests pursuant to Section 4.01(q), the REMIC
I Principal Balance of the Corresponding REMIC I Regular Interest (after taking
account of such deemed distributions) for each Class of Class WW Principal
Balance Certificates shall be reduced as a result of Realized Losses and
Additional Trust Fund Expenses to equal the Class Principal Balance of such
Class of Class WW Principal Balance Certificates that will be outstanding
immediately following such Distribution Date.

     On any Distribution Date, the amount of any Mortgage Deferred Interest in
respect of the 77 West Wacker Drive Mortgage Loan will be allocated as
Certificate Deferred Interest to each outstanding Class of Class WW Principal
Balance Certificates in reverse numerical order, in each case up to the
respective Accrued Certificate Interest for each such Class of Certificates for
such Distribution Date, and then as Certificate Deferred Interest on the
Sequential Pay Certificates as provided in this Agreement. On each such
Distribution Date, the Class Principal Balance of each such Class of
Certificates to which Certificate Deferred Interest has been allocated will be
increased by the amount of Certificate Deferred Interest allocated to

                                      223
<PAGE>

such Class. The amount of Certificate Deferred Interest allocated to any such
Class of Certificates will be allocated to, and will increase the REMIC I
Principal Balances of, the Corresponding REMIC I Regular Interest.

     SECTION 4.05   Calculations.

     The Trustee shall, provided it receives the necessary information from the
Master Servicer and the Special Servicer, be responsible for performing all
calculations necessary in connection with the actual and deemed distributions
and allocations to be made pursuant to Section 4.01, Section 5.02(d) and Article
IX and the actual and deemed allocations of Realized Losses and Additional Trust
Fund Expenses to be made pursuant to Section 4.04. The Trustee shall calculate
the Available Distribution Amount for each Distribution Date and shall allocate
such amount among Certificateholders in accordance with this Agreement, and the
Trustee shall have no obligation to recompute, recalculate or verify any
information provided to it by the Special Servicer or Master Servicer. The
calculations by the Trustee of such amounts shall, in the absence of manifest
error, be presumptively deemed to be correct for all purposes hereunder.

     SECTION 4.06   Use of Agents.

     The Master Servicer, the Trustee or the Fiscal Agent may at its own expense
utilize agents or attorneys-in-fact in performing any of its obligations under
this Article IV (except the obligation to make P&I Advances), but no such
utilization shall relieve the Master Servicer, the Trustee or the Fiscal Agent
from any of such obligations or liabilities, and the Master Servicer, the
Trustee or the Fiscal Agent, as applicable, shall remain responsible for all
acts and omissions of any such agent or attorney-in-fact (other than with
respect to limited powers-of-attorney delivered by the Trustee to the Master
Servicer or Special Servicer pursuant to Section 2.03(b) and 3.01(b), as
applicable, in which case the Trustee shall have no such responsibility).

                                    ARTICLE V

                                THE CERTIFICATES

     SECTION 5.01   The Certificates.

     (a) The Certificates will be substantially in the respective forms attached
hereto as Exhibit A; provided that any of the Certificates may be issued with
appropriate insertions, omissions, substitutions and variations, and may have
imprinted or otherwise reproduced thereon such legend or legends, not
inconsistent with the provisions of this Agreement, as may be required to comply
with any law or with rules or regulations pursuant thereto, or with the rules of
any securities market in which the Certificates are admitted to trading, or to
conform to general usage. The Certificates will be issuable in registered form
only; provided, however, that in accordance with Section 5.03 beneficial
ownership interests in the Regular Certificates shall initially be held and
transferred through the book-entry facilities of the Depository. The Regular
Certificates will be issuable only in denominations corresponding to initial
Certificate Principal Balances or initial Certificate Notional Amounts, as the
case may be, as of the Closing Date of not less than $25,000 in the case of the
Registered Certificates and not less than $100,000 in the

                                      224
<PAGE>

case of Non-Registered Certificates (other than the Residual Certificates and
the Class Z-I and Class Z-II Certificates), and in each such case in integral
multiples of $1 in excess thereof. The Residual Certificates, Class Z-I
Certificates and Class Z-II Certificates shall have no minimum denomination and
shall each be represented by a single definitive certificate.

     (b) The Certificates shall be executed by manual or facsimile signature on
behalf of the Trustee by the Certificate Registrar hereunder by an authorized
signatory. Certificates bearing the manual or facsimile signatures of
individuals who were at any time the authorized officers of the Certificate
Registrar shall be entitled to all benefits under this Agreement, subject to the
following sentence, notwithstanding that such individuals or any of them have
ceased to hold such offices prior to the authentication and delivery of such
Certificates or did not hold such offices at the date of such Certificates. No
Certificate shall be entitled to any benefit under this Agreement, or be valid
for any purpose, however, unless there appears on such Certificate a certificate
of authentication substantially in the form provided for herein executed by the
Authenticating Agent by manual signature, and such certificate of authentication
upon any Certificate shall be conclusive evidence, and the only evidence, that
such Certificate has been duly authenticated and delivered hereunder. All
Certificates shall be dated the date of their authentication.

     SECTION 5.02   Registration of Transfer and Exchange of Certificates.

     (a) At all times during the term of this Agreement, there shall be
maintained at the office of the Certificate Registrar a Certificate Register in
which, subject to such reasonable regulations as the Certificate Registrar may
prescribe, the Certificate Registrar (located as of the Closing Date at LaSalle
Bank National Association, 135 S. LaSalle Street, Suite 1625, Chicago, IL 60603,
shall provide for the registration of Certificates and of transfers and
exchanges of Certificates as herein provided. The Trustee is hereby initially
appointed (and hereby agrees to act in accordance with the terms hereof) as
Certificate Registrar for the purpose of registering Certificates and transfers
and exchanges of Certificates as herein provided. The Certificate Registrar may
appoint, by a written instrument delivered to the Depositor, the Trustee, the
Special Servicer and the Master Servicer, any other bank or trust company to act
as Certificate Registrar under such conditions as the predecessor Certificate
Registrar may prescribe, provided that the predecessor Certificate Registrar
shall not be relieved of any of its duties or responsibilities hereunder by
reason of such appointment. If the Trustee resigns or is removed in accordance
with the terms hereof, the successor trustee shall immediately succeed to its
duties as Certificate Registrar. The Depositor, the Trustee (if it is no longer
the Certificate Registrar), the Master Servicer and the Special Servicer shall
have the right to inspect the Certificate Register or to obtain a copy thereof
at all reasonable times, and to rely conclusively upon a certificate of the
Certificate Registrar as to the information set forth in the Certificate
Register. Upon written request of any Certificateholder made for purposes of
communicating with other Certificateholders with respect to their rights under
this Agreement, the Certificate Registrar shall promptly furnish such
Certificateholder with a list of the other Certificateholders of record
identified in the Certificate Register at the time of the request.

     (b) With respect to any offer, sale, pledge or other transfer, no such
transfer of any Non-Registered Certificate shall be made unless that transfer is
made pursuant to an effective registration statement under the Securities Act,
and effective registration or

                                      225
<PAGE>

qualification under applicable state securities laws, or is made in a
transaction that does not require such registration or qualification. If such a
transfer is to be made without registration under the Securities Act (other than
in connection with the initial issuance thereof or a transfer thereof by the
Depositor, Merrill Lynch, Pierce, Fenner and Smith Incorporated, J.P. Morgan
Securities Inc. or their respective Affiliates), then the Certificate Registrar
shall refuse to register such transfer unless it receives (and upon receipt, may
conclusively rely upon) either: (i) a certificate from the Certificateholder
desiring to effect such transfer substantially in the form attached as Exhibit
E-1 hereto, and a certificate from such Certificateholder's prospective
transferee substantially in the form attached as either Exhibit E-2 hereto or as
Exhibit E-3 hereto; or (ii) an Opinion of Counsel reasonably satisfactory to the
Certificate Registrar to the effect that such transfer may be made without
registration under the Securities Act (which Opinion of Counsel shall not be an
expense of the Trust Fund or of the Depositor, the Master Servicer, the Special
Servicer, the Trustee or the Certificate Registrar in their respective
capacities as such), together with the written certification(s) as to the facts
surrounding such transfer from the Certificateholder desiring to effect such
transfer and/or such Certificateholder's prospective transferee on which such
Opinion of Counsel is based. None of the Depositor, the Trustee or the
Certificate Registrar is obligated to register or qualify any Class of
Non-Registered Certificates under the Securities Act or any other securities law
or to take any action not otherwise required under this Agreement to permit the
transfer of any Non-Registered Certificate without registration or
qualification. Any Holder of a Non-Registered Certificate desiring to effect
such a transfer shall, and upon acquisition of such a Certificate shall be
deemed to have agreed to, indemnify the Trustee, the Certificate Registrar and
the Depositor against any liability that may result if the transfer is not so
exempt or is not made in accordance with such federal and state laws.

     In connection with transfer of the Non-Registered Certificates, the
Depositor shall furnish upon request of a Certificateholder or Certificate Owner
to such Holder or Certificate Owner and any prospective purchaser designated by
such Certificateholder or Certificate Owner the information required to be
delivered under paragraph (d)(4) of Rule 144A of the Securities Act.

     With respect to any offer, sale, pledge or other transfer of any Class of
Non-Registered Certificates that constitutes a Class of Book-Entry Certificates,
if such a transfer is to be made without registration under the Securities Act
(other than in connection with the initial issuance thereof or a transfer
thereof by the Depositor, Merrill Lynch, Pierce, Fenner and Smith Incorporated,
J.P. Morgan Securities Inc. or their respective Affiliates), such transfer will
not be made unless the prospective transferee delivers to the transferor (i) a
certificate substantially in the form of Exhibit E-2 hereto and addressed to the
transferor, upon or prior to such transfer, or (ii) an opinion of counsel to the
effect that such transferee is a QIB and that such transfer may be made without
registration under the Securities Act, together with the written
certification(s) as to the facts surrounding such transfer, from the prospective
transferor desiring to effect such transfer and/or the prospective transferee,
on which such opinion of counsel is based. In any event, (a) each prospective
transferor of such Certificate will be deemed to have represented to the
Trustee, the Depositor and the transferee of such Certificate the information
set forth on Exhibit E-1 upon or prior to such transfer and (b) each prospective
transferee of such Certificate will be deemed to have represented to the
Trustee, the Depositor and the transferor of such Certificate the information
set forth on Exhibit E-2 hereto.

                                      226
<PAGE>

     An Institutional Accredited Investor (other than a QIB) may not hold an
interest in a Class of Non-Registered Certificates in book-entry form and must
hold such Non-Registered Certificates in definitive form. Any transfer of such
Certificates will require, among other things described in this Agreement,
delivery of the certifications and/or opinions required in connection with the
transfer of a Non-Registered Certificate held in a physical certificated form,
as set forth above.

     (c) No transfer of a Certificate or any interest therein  shall be made to
any "employee benefit plan" subject to Title I of ERISA, any "plan" described by
Section 4975(e)(1) of the Code that is subject to Section 4975 of the Code or
any other retirement plan or other employee benefit plan or arrangement subject
to applicable federal, state or local law ("Similar Law") materially similar to
the foregoing provisions of ERISA and the Code, or any entity deemed to hold
plan assets of the foregoing by reason of such a plan's investment in such
entity (each, a "Plan") unless (A) in the case of a Certificate other than a
Residual Certificate, a Class Z-I Certificate or a Class Z-II Certificate, the
transferee is an insurance company general account and (1) it is eligible for,
and satisfies all the requirements of, exemptive relief under Sections I and III
of Department of Labor Prohibited Transaction Class Exemption 95-60 ("PTCE
95-60"), including the requirement that there is no "plan" (as defined in PTCE
95-60) with respect to which the amount of such general account's reserves and
liabilities for contracts held by or on behalf of such plan and all other plans
maintained by the same employer (or any "affiliate" thereof as defined in PTCE
95-60) or by the same employee organization exceeds 10% of the total of all
reserves and liabilities of such general account (as determined under PTCE
95-60), and will continue to satisfy such requirements thereafter, (2) each Plan
invested in such general account qualifies as an accredited investor as defined
in Rule 501(a)(1) of Regulation D under the Securities Act and (3) it will
obtain from each of its transferees that is an insurance company general account
a written representation that such transferee satisfies the requirements
described in the preceding clauses (1) and (2) and a written agreement of the
type described in this clause (3), or (B) in the case of a Certificate other
than an ERISA Restricted Certificate, a Residual Certificate, a Class Z-I
Certificate or a Class Z-II Certificate, the transferee (1) qualifies as an
accredited investor as defined in Rule 501(a)(1) of Regulation D under the
Securities Act and (2) satisfies all the requirements of the Exemption as in
effect at the time of such transfer. Except in connection with the initial
issuance thereof or a transfer thereof by the Depositor, Merrill Lynch, Pierce,
Fenner and Smith Incorporated, J.P. Morgan Securities Inc. or their respective
Affiliates, each person who acquires a Certificate in Definitive Certificate
form shall be required to certify in writing in the form attached as Exhibit F
hereto that it meets the foregoing conditions and that it will not transfer such
Certificate in violation of the foregoing. Each Person who acquires a
Certificate in Book-Entry Certificate form shall be deemed to have represented
that the foregoing conditions are satisfied and that it will not transfer such
Certificate in violation of the foregoing.

     (d) (i) Each Person who has or who acquires any Ownership Interest in a
Residual Certificate shall be deemed by the acceptance or acquisition of such
Ownership Interest to have agreed to be bound by the following provisions and to
have irrevocably authorized the Trustee under clause (ii)(A) below to deliver
payments to a Person other than such Person and to have irrevocably authorized
the Certificate Registrar under clause (ii)(B) below to negotiate the terms of
any mandatory disposition and to execute all instruments of Transfer and to do
all other things necessary in connection with any such sale. The rights of each
Person acquiring any Ownership Interest in a Residual Certificate are expressly
subject to the following provisions:

                                      227
<PAGE>

               (1) Each Person holding or acquiring any Ownership Interest in a
          Residual Certificate shall be a Permitted Transferee and shall
          promptly notify the Master Servicer, the Trustee and the Certificate
          Registrar of any change or impending change in its status as a
          Permitted Transferee.

               (2) In connection with any proposed Transfer of any Ownership
          Interest in a Residual Certificate, the Certificate Registrar shall
          require delivery to it, and shall not register the Transfer of any
          Residual Certificate until its receipt of an affidavit and agreement
          substantially in the form attached hereto as Exhibit G-1 (a "Transfer
          Affidavit and Agreement"), from the proposed Transferee, in form and
          substance satisfactory to the Certificate Registrar, and upon which
          the Certificate Registrar may, in the absence of actual knowledge by a
          Responsible Officer of either the Trustee or the Certificate Registrar
          to the contrary, conclusively rely, representing and warranting, among
          other things, that such Transferee is a Permitted Transferee, that it
          is not acquiring its Ownership Interest in the Residual Certificate
          that is the subject of the proposed Transfer as a nominee, trustee or
          agent for any Person that is not a Permitted Transferee, that for so
          long as it retains its Ownership Interest in a Residual Certificate,
          it will endeavor to remain a Permitted Transferee, that it has
          historically paid its debts as they have come due, intends to pay its
          debts as they come due in the future and intends to pay all taxes
          associated with the Residual Certificate as they come due and that it
          has reviewed the provisions of this Section 5.02(d) and agrees to be
          bound by them.

               (3) Notwithstanding the delivery of a Transfer Affidavit and
          Agreement by a proposed Transferee under clause (B) above, if a
          Responsible Officer of the Certificate Registrar has actual knowledge
          that the proposed Transferee is not a Permitted Transferee, no
          Transfer of an Ownership Interest in a Residual Certificate to such
          proposed Transferee shall be effected.

               (4) Each Person holding or acquiring any Ownership Interest in a
          Residual Certificate shall agree (1) to require a Transfer Affidavit
          and Agreement from any prospective Transferee to whom such Person
          attempts to transfer its Ownership Interest in such Residual
          Certificate and (2) not to transfer its Ownership Interest in such
          Residual Certificate unless it provides to the Certificate Registrar a
          certificate substantially in the form attached hereto as Exhibit G-2
          stating that, among other things, it has no actual knowledge that such
          prospective Transferee is not a Permitted Transferee.

               (5) Each Person holding or acquiring an Ownership Interest in a
          Residual Certificate, by purchasing an Ownership Interest in such
          Certificate, agrees to give the Master Servicer and the Trustee
          written notice that it is a "pass-through interest holder" within the
          meaning of

                                      228
<PAGE>

          temporary Treasury regulation Section 1.67-3T(a)(2)(i)(A) immediately
          upon acquiring an Ownership Interest in a Residual Certificate, if it
          is, or is holding an Ownership Interest in a Residual Certificate on
          behalf of, a "pass-through interest holder".

          (ii) (A) If any purported Transferee shall become a Holder of a
     Residual Certificate in violation of the provisions of this Section
     5.02(d), then the last preceding Holder of such Residual Certificate that
     was in compliance with the provisions of this Section 5.02(d) shall be
     restored, to the extent permitted by law, to all rights as Holder thereof
     retroactive to the date of registration of such Transfer of such Residual
     Certificate. None of the Trustee, the Master Servicer or the Certificate
     Registrar shall be under any liability to any Person for any registration
     of Transfer of a Residual Certificate that is in fact not permitted by this
     Section 5.02(d) or for making any payments due on such Certificate to the
     Holder thereof or for taking any other action with respect to such Holder
     under the provisions of this Agreement.

          (B) If any purported Transferee shall become a Holder of a Residual
     Certificate in violation of the restrictions in this Section 5.02(d), then,
     to the extent that the retroactive restoration of the rights of the
     preceding Holder of such Residual Certificate as described in clause
     (ii)(A) above shall be invalid, illegal or unenforceable, the Certificate
     Registrar shall have the right, without notice to the Holder or any prior
     Holder of such Residual Certificate, to cause the transfer of such Residual
     Certificate to a Permitted Transferee on such terms as the Certificate
     Registrar may choose. Such purported Transferee shall promptly endorse and
     deliver such Residual Certificate in accordance with the instructions of
     the Certificate Registrar. Such Permitted Transferee may be the Certificate
     Registrar itself or any Affiliate of the Certificate Registrar. Any
     proceeds of such sale, net of the commissions (which may include
     commissions payable to the Certificate Registrar or its Affiliates),
     expenses and taxes due, if any, will be remitted by the Trustee to such
     purported Transferee. The terms and conditions of any sale under this
     clause (ii)(B) shall be determined in the sole discretion of the
     Certificate Registrar, and the Certificate Registrar shall not be liable to
     any Person having an Ownership Interest in a Residual Certificate as a
     result of its exercise of such discretion.

          (iii) The Certificate Registrar shall make available to the Internal
     Revenue Service and to those Persons specified by the REMIC Provisions any
     information available to it which is necessary to compute any tax imposed
     as a result of the Transfer of an Ownership Interest in a Residual
     Certificate to any Person who is a Disqualified Organization or agent
     thereof, including the information described in Treasury Regulations
     Sections 1.860D-1(b)(5) and 1.860E-2(a)(5) with respect to the "excess
     inclusions" of such Residual Certificate, and the Master Servicer and the
     Special Servicer shall furnish to the Certificate Registrar all information
     in its possession necessary for the Certificate Registrar to discharge such
     obligation. The transferor of such Ownership Interest

                                      229
<PAGE>

     shall be responsible for the reasonable compensation of the Certificate
     Registrar, the Master Servicer and the Special Servicer for providing such
     information.

          (iv) The provisions of this Section 5.02(d) set forth prior to this
     clause (iv) may be modified, added to or eliminated, provided that there
     shall have been delivered to the Certificate Registrar and the Master
     Servicer the following:

          (1) written confirmation from each Rating Agency to the effect that
     the modification of, addition to or elimination of such provisions will not
     cause such Rating Agency to qualify, downgrade or withdraw its then-current
     rating of any Class of Certificates; and

          (2) an Opinion of Counsel, in form and substance satisfactory to the
     Certificate Registrar and the Master Servicer, obtained at the expense of
     the party seeking such modification of, addition to or elimination of such
     provisions (but in no event at the expense of the Trust Fund), to the
     effect that doing so will not cause the 77 West Wacker Drive Loan REMIC,
     REMIC I or REMIC II to (x) cease to qualify as a REMIC or (y) be subject to
     an entity-level tax caused by the Transfer of any Residual Certificate to a
     Person which is not a Permitted Transferee, or cause a Person other than
     the prospective Transferee to be subject to a REMIC-related tax caused by
     the Transfer of a Residual Certificate to a Person that is not a Permitted
     Transferee.

     (e) Subject to the preceding provisions of this Section 5.02, upon
surrender for registration of transfer of any Certificate at the offices of the
Certificate Registrar maintained for such purpose, the Certificate Registrar
shall execute and the Authenticating Agent shall authenticate and deliver, in
the name of the designated transferee or transferees, one or more new
Certificates of the same Class of a like aggregate Percentage Interest.

     (f) At the option of any Holder, its Certificates may be exchanged for
other Certificates of authorized denominations of the same Class of a like
aggregate Percentage Interest, upon surrender of the Certificates to be
exchanged at the offices of the Certificate Registrar maintained for such
purpose. Whenever any Certificates are so surrendered for exchange, the
Certificate Registrar shall execute and the Authenticating Agent shall
authenticate and deliver the Certificates which the Certificateholder making the
exchange is entitled to receive.

     (g) Every Certificate presented or surrendered for transfer or exchange
shall (if so required by the Certificate Registrar) be duly endorsed by, or be
accompanied by a written instrument of transfer in the form satisfactory to the
Certificate Registrar duly executed by, the Holder thereof or his attorney duly
authorized in writing.

     (h) No service charge shall be imposed for any transfer or exchange of
Certificates, but the Certificate Registrar may require payment of a sum
sufficient to cover any tax or other governmental charge that may be imposed in
connection with any transfer or exchange of Certificates.

                                      230
<PAGE>

     (i) All Certificates surrendered for transfer and exchange shall be
physically canceled by the Certificate Registrar, and the Certificate Registrar
shall dispose of such canceled Certificates in accordance with its standard
procedures.

     (j) Upon request, the Certificate Registrar shall provide to the Master
Servicer, the Special Servicer and the Depositor notice of each transfer of a
Certificate and shall provide to each such Person with an updated copy of the
Certificate Register.

     SECTION 5.03   Book-Entry Certificates.

     (a) Each Class of Regular Certificates shall initially be issued as one or
more Certificates registered in the name of the Depository or its nominee and,
except as provided in Section 5.03(c) below, transfer of such Certificates may
not be registered by the Certificate Registrar unless such transfer is to a
successor Depository that agrees to hold such Certificates for the respective
Certificate Owners with Ownership Interests therein. Such Certificate Owners
shall hold and transfer their respective Ownership Interests in and to such
Certificates through the book-entry facilities of the Depository and, except as
provided in Section 5.03(c) below, shall not be entitled to definitive, fully
registered Certificates ("Definitive Certificates") in respect of such Ownership
Interests. All transfers by Certificate Owners of their respective Ownership
Interests in the Book-Entry Certificates shall be made in accordance with the
procedures established by the Depository Participant or brokerage firm
representing each such Certificate Owner. Each Depository Participant shall only
transfer the Ownership Interests in the Book-Entry Certificates of Certificate
Owners it represents or of brokerage firms for which it acts as agent in
accordance with the Depository's normal procedures.

     (b) The Trustee, the Master Servicer, the Special Servicer, the Depositor
and the Certificate Registrar may for all purposes, including the making of
payments due on the Book-Entry Certificates, deal with the Depository as the
authorized representative of the Certificate Owners with respect to such
Certificates for the purposes of exercising the rights of Certificateholders
hereunder. The rights of Certificate Owners with respect to the Book-Entry
Certificates shall be limited to those established by law and agreements between
such Certificate Owners and the Depository Participants and brokerage firms
representing such Certificate Owners. Multiple requests and directions from, and
votes of, the Depository as Holder of the Book-Entry Certificates with respect
to any particular matter shall not be deemed inconsistent if they are made with
respect to different Certificate Owners. The Trustee may establish a reasonable
record date in connection with solicitations of consents from or voting by
Certificateholders and shall give notice to the Depository of such record date.

     (c) If (i)(A) the Depositor advises the Trustee and the Certificate
Registrar in writing that the Depository is no longer willing or able to
properly discharge its responsibilities with respect to a Class of the
Book-Entry Certificates, and (B) the Depositor is unable to locate a qualified
successor, or (ii) the Depositor at its option advises the Trustee and the
Certificate Registrar in writing that it elects to terminate the book-entry
system through the Depository with respect to a Class of Book-Entry
Certificates, the Certificate Registrar shall notify all affected Certificate
Owners, through the Depository, of the occurrence of any such event and of the
availability of Definitive Certificates to such Certificate Owners requesting
the same. Upon surrender to the Certificate Registrar of the Book-Entry
Certificates of any Class thereof by the

                                      231
<PAGE>

Depository, accompanied by registration instructions from the Depository for
registration of transfer, the Certificate Registrar shall execute, at the
Depositor's expense, and the Authenticating Agent shall authenticate and
deliver, the Definitive Certificates in respect of such Class to the Certificate
Owners identified in such instructions. The Depositor shall provide the
Certificate Registrar with an adequate inventory of Definitive Certificates.
None of the Depositor, the Master Servicer, the Special Servicer, the Trustee or
the Certificate Registrar shall be liable for any delay in delivery of such
instructions and may conclusively rely on, and shall be protected in relying on,
such instructions. Upon the issuance of Definitive Certificates for purposes of
evidencing ownership of any Class of Registered Certificates, the registered
holders of such Definitive Certificates shall be recognized as
Certificateholders hereunder and, accordingly, shall be entitled directly to
receive payments on, to exercise Voting Rights with respect to, and to transfer
and exchange such Definitive Certificates.

     (d) Notwithstanding any other provisions contained herein, neither the
Trustee nor the Certificate Registrar shall have any responsibility whatsoever
to monitor or restrict the transfer of ownership interests in any Certificate
(including but not limited to any Non-Registered Certificate or any Subordinated
Certificate) which interests are transferable through the book-entry facilities
of the Depository.

     SECTION 5.04   Mutilated, Destroyed, Lost or Stolen Certificates.

     If (i) any mutilated Certificate is surrendered to the Certificate
Registrar, or the Certificate Registrar receives evidence to its satisfaction of
the destruction, loss or theft of any Certificate, and (ii) there is delivered
to the Trustee and the Certificate Registrar such security or indemnity as may
be required by them to save each of them harmless, then, in the absence of
actual notice to the Trustee and the Certificate Registrar that such Certificate
has been acquired by a bona fide purchaser, the Certificate Registrar shall
execute and the Authenticating Agent shall authenticate and deliver, in exchange
for or in lieu of any such mutilated, destroyed, lost or stolen Certificate, a
new Certificate of the same Class and like Percentage Interest. Upon the
issuance of any new Certificate under this Section, the Trustee and the
Certificate Registrar may require the payment of a sum sufficient to cover any
tax or other governmental charge that may be imposed in relation thereto and any
other expenses (including the fees and expenses of the Trustee and the
Certificate Registrar) connected therewith. Any replacement Certificate issued
pursuant to this Section shall constitute complete and indefeasible evidence of
ownership in the applicable REMIC created hereunder, as if originally issued,
whether or not the lost, stolen or destroyed Certificate shall be found at any
time.

     SECTION 5.05   Persons Deemed Owners.

     Prior to due presentment for registration of transfer, the Depositor, the
Master Servicer, the Special Servicer, the Trustee, the Certificate Registrar
and any agent of any of them may treat the Person in whose name any Certificate
is registered as of the related Record Date as the owner of such Certificate for
the purpose of receiving distributions pursuant to Section 4.01 and may treat
the person whose name each Certificate is registered as of the date of
determination as the owner of such Certificate for all other purposes whatsoever
and none of the Depositor, the Master Servicer, the Special Servicer, the
Trustee, the Certificate Registrar or any agent of any of them shall be affected
by notice to the contrary.

                                   ARTICLE VI

          THE DEPOSITOR, THE MASTER SERVICER, THE SPECIAL SERVICER, THE
           CONTROLLING CLASS REPRESENTATIVE, AND THE COMPANION PAYING
                                      AGENT

     SECTION 6.01   Liability of Depositor, Master Servicer and Special
Servicer.

     The Depositor, the Master Servicer and the Special Servicer shall be liable
in accordance herewith only to the extent of the respective obligations
specifically imposed upon and undertaken by the Depositor, the Master Servicer
and the Special Servicer herein.

     SECTION 6.02   Merger, Consolidation or Conversion of Depositor or Master
Servicer or Special Servicer.

     Subject to the following paragraph, the Depositor, the Master Servicer and
the Special Servicer shall each keep in full effect its existence, rights and
franchises as a corporation under the laws of the jurisdiction of its
incorporation or organization, and each will obtain and preserve its
qualification to do business as a foreign corporation in each jurisdiction in
which such qualification is or shall be necessary to protect the validity and
enforceability of this Agreement, the Certificates or any of the Mortgage Loans
and to perform its respective duties under this Agreement.

     The Depositor, the Master Servicer or the Special Servicer may be merged or
consolidated with or into any Person (other than the Trustee), or transfer all
or substantially all of its assets (which may be limited to all or substantially
all of its assets related to commercial mortgage loan servicing) to any Person,
in which case any Person resulting from any merger or consolidation to which the
Depositor, the Master Servicer or the Special Servicer shall be a party, or any
Person succeeding to the business (which may be limited to the commercial loan
servicing business) of the Depositor, the Master Servicer or the Special
Servicer, shall be the successor of the Depositor, the Master Servicer or the
Special Servicer, as the case may be, hereunder, without the execution or filing
of any paper or any further act on the part of any of the parties hereto,
anything herein to the contrary notwithstanding; provided, however, that no
successor or surviving Person shall succeed to the rights of the Master Servicer
or the Special Servicer unless (i) as evidenced in writing by the Rating
Agencies, such succession will not result in qualification, downgrading or
withdrawal of the ratings then assigned by the Rating Agencies to any Class of
Certificates and (ii) such successor or surviving Person makes the applicable
representations and warranties set forth in Section 3.23.

     SECTION 6.03   Limitation on Liability of the Depositor, the Master
Servicer, the Special Servicer and Others.

     (a) None of the Depositor, the Master Servicer, the Special Servicer nor
any of the Affiliates, directors, partners, members, managers, shareholders,
officers, employees or agents of any of them shall be under any liability to the
Trust Fund, the Underwriters, the parties hereto, the Certificateholders, any
Companion Holder or any other Person for any action taken or

                                      233
<PAGE>

for refraining from the taking of any action in good faith pursuant to this
Agreement, or for errors in judgment; provided, however, that this provision
shall not protect the Depositor, the Master Servicer, the Special Servicer nor
any of the Affiliates, directors, partners, members, managers, shareholders,
officers, employees or agents of any of them against any liability to the Trust
Fund, the Trustee, the Certificateholders, any Companion Holder or any other
Person for the breach of warranties or representations made herein by such
party, or against any liability which would otherwise be imposed by reason of
willful misfeasance, bad faith or negligence in the performance of obligations
or duties hereunder. The Depositor, the Master Servicer, the Special Servicer
and any director, officer, employee or agent of the Depositor, the Master
Servicer or the Special Servicer may rely in good faith on any document of any
kind which, prima facie, is properly executed and submitted by any Person
respecting any matters arising hereunder.

     The Depositor, the Master Servicer, the Special Servicer, and any
Affiliate, director, shareholder, member, partner, manager, officer, employee or
agent of any of the foregoing shall be indemnified and held harmless by the
Trust Fund out of the Certificate Account or the Distribution Account, as
applicable in accordance with Section 3.05 (or, insofar as a Loan Pair is
involved, and to the extent permitted by the related Intercreditor Agreement,
out of amounts attributable to such Loan Pair on deposit in the related
Companion Loan Custodial Account as provided in Section 3.04), against any loss,
liability or expense (including reasonable legal fees and expenses) incurred in
connection with any legal action or claim relating to this Agreement, the
Mortgage Loans or the Certificates (including, without limitation, the
distribution or posting of reports or other information as contemplated by this
Agreement), other than any loss, liability or expense: (i) specifically required
to be borne thereby pursuant to the terms hereof or that would otherwise
constitute a Servicing Advance; (ii) incurred in connection with any breach of a
representation or warranty made by it herein; (iii) incurred by reason of bad
faith, willful misconduct or negligence in the performance of its obligations or
duties hereunder or (iv) incurred in connection with any violation by any of
them of any state or federal securities law.

     (b) None of the Depositor, the Master Servicer or the Special Servicer
shall be under any obligation to appear in, prosecute or defend any legal or
administrative action, proceeding, hearing or examination that is not incidental
to its respective duties under this Agreement and which in its opinion may
involve it in any expense or liability which it is not reasonably assured of
reimbursement thereof by the Trust; provided, however, that the Depositor, the
Master Servicer or the Special Servicer may in its discretion undertake any such
action, proceeding, hearing or examination that it may deem necessary or
desirable in respect to this Agreement and the rights and duties of the parties
hereto and the interests of the Certificateholders hereunder. In such event, the
reasonable legal fees, expenses and costs of such action, proceeding, hearing or
examination and any liability resulting therefrom shall be expenses, costs and
liabilities of the Trust Fund, and the Depositor, the Master Servicer and the
Special Servicer shall be entitled to be reimbursed therefor out of amounts
attributable to the Mortgage Loans on deposit in the Certificate Account as
provided by Section 3.05(a) (or, insofar as a Loan Pair is involved, and to the
extent permitted by the related Intercreditor Agreement, out of amounts
attributable to such Loan Pair on deposit in the related Companion Loan
Custodial Account as provided in Section 3.04).

                                      234
<PAGE>

     In no event shall the Master Servicer or the Special Servicer be liable or
responsible for any action taken or omitted to be taken by the other of them or
by the Depositor, the Trustee or any Certificateholder, subject to the
provisions of Section 8.05(b).

     (c) Each of the Master Servicer and the Special Servicer agrees to
indemnify the Depositor, the Trust Fund and the Trustee and any Affiliate,
director, officer, employee or agent thereof, and hold it harmless, from and
against any and all claims, losses, penalties, fines, forfeitures, reasonable
legal fees and related out-of-pocket costs, judgments, and any other
out-of-pocket costs, liabilities, fees and expenses that any of them may sustain
arising from or as a result of any willful misfeasance, bad faith or negligence
of the Master Servicer or the Special Servicer, as the case may be, in the
performance of its obligations and duties under this Agreement or by reason of
negligent disregard by the Master Servicer or the Special Servicer, as the case
may be, of its duties and obligations hereunder or by reason of breach of any
representations or warranties made by it herein. The Master Servicer and the
Special Servicer may consult with counsel, and any written advice or Opinion of
Counsel shall be full and complete authorization and protection with respect to
any action taken or suffered or omitted by it hereunder in good faith in
accordance with the Servicing Standard and in accordance with such advice or
Opinion of Counsel relating to (i) tax matters, (ii) any amendment of this
Agreement under Article XI, (iii) the defeasance of any Defeasance Mortgage Loan
or (iv) any matter involving legal proceedings with a Mortgagor.

     The Trustee shall immediately notify the Master Servicer or the Special
Servicer, as applicable, if a claim is made by a third party with respect to
this Agreement or the Mortgage Loans entitling the Trust Fund or the Trustee to
indemnification hereunder, whereupon the Master Servicer or Special Servicer, as
the case may be, shall assume the defense of such claim and pay all expenses in
connection therewith, including counsel fees, and promptly pay, discharge and
satisfy any judgment or decree which may be entered against it or them in
respect of such claim. Any failure to so notify the Master Servicer or Special
Servicer, as the case may be, shall not affect any rights that the Trust Fund or
the Trustee, as the case may be, may have to indemnification under this
Agreement or otherwise, unless the Master Servicer's or Special Servicer's, as
the case may be, defense of such claim is materially prejudiced thereby. The
indemnification provided herein shall survive the termination of this Agreement
and the termination or resignation of the indemnifying party.

     The Depositor shall immediately notify the Master Servicer or the Special
Servicer, as applicable, if a claim is made by a third party with respect to
this Agreement or the Mortgage Loans entitling the Depositor to indemnification
hereunder, whereupon the Master Servicer or Special Servicer, as the case may
be, shall assume the defense of such claim and pay all expenses in connection
therewith, including counsel fees, and promptly pay, discharge and satisfy any
judgment or decree which may be entered against it or them in respect of such
claim. Any failure to so notify the Master Servicer or Special Servicer, as the
case may be, shall not affect any rights that the Depositor may have to
indemnification under this Agreement or otherwise, unless the Master Servicer's
or Special Servicer's, as the case may be, defense of such claim is materially
prejudiced thereby. The indemnification provided herein shall survive the
termination of this Agreement and the termination or resignation of the

that any of them may sustain arising from or as a result of any breach of
representations and warranties or the willful misfeasance, bad faith or
negligence of the Depositor in the performance of the Depositor's obligations
and duties under this Agreement. The Master Servicer, the Special Servicer or
the Trustee, as applicable, shall immediately notify the Depositor if a claim is
made by a third party with respect to this Agreement or the Mortgage Loans
entitling it to indemnification hereunder, whereupon the Depositor shall assume
the defense of such claim and pay all expenses in connection therewith,

The indemnification provided herein shall survive the termination of this
Agreement.

     The Trustee agrees to indemnify the Master Servicer, the Special Servicer

costs, judgments, and any other out-of-pocket costs, liabilities, fees and
expenses that any of them may sustain arising from or as a result of any breach
of representations and warranties made by it herein or as a result of any
willful misfeasance, bad faith or negligence of the Trustee in the performance
of its obligations and duties under this Agreement or the negligent disregard by
the Trustee of its duties and obligations hereunder. The Depositor, Master
Servicer or the Special Servicer, as applicable, shall immediately notify the
Trustee if a claim is made by a third party with respect to this Agreement or
the Mortgage Loans entitling it to indemnification hereunder, whereupon the

termination of this Agreement and the termination or resignation of the
indemnifying party.

     SECTION 6.04   Resignation of Master Servicer and the Special Servicer.

     The Master Servicer and, subject to Section 6.09, the Special Servicer may
resign from the obligations and duties hereby imposed on it, upon a
determination that its duties hereunder are no longer permissible under
applicable law or are in material conflict by reason of applicable law with any
other activities carried on by it (the other activities of the Master Servicer
or the Special Servicer, as the case may be, so causing such a conflict being of
a type and nature carried on by the Master Servicer or the Special Servicer, as
the case may be, at the date of this Agreement). Any such determination
requiring the resignation of the Master Servicer or the Special Servicer, as
applicable, shall be evidenced by an Opinion of Counsel to such effect which
shall be delivered to the Trustee. Unless applicable law requires the Master

                                      236
<PAGE>

Servicer's or Special Servicer's resignation to be effective immediately, and
the Opinion of Counsel delivered pursuant to the prior sentence so states, no
such resignation shall become effective until the Trustee or other successor
shall have assumed the responsibilities and obligations of the resigning party
in accordance with Section 7.02 hereof. The Master Servicer and the Special
Servicer shall have the right to resign at any other time provided that (i) a
willing successor thereto has been found by the Master Servicer or Special
Servicer, as applicable, (ii) each of the Rating Agencies confirms in writing
that the successor's appointment will not result in a withdrawal, qualification
or downgrade of any rating or ratings assigned to any Class of Certificates,
(iii) the resigning party pays all costs and expenses in connection with such
transfer, and (iv) the successor accepts appointment prior to the effectiveness
of such resignation. Neither the Master Servicer nor the Special Servicer shall
be permitted to resign except as contemplated above in this Section 6.04.

     Consistent with the foregoing, neither the Master Servicer nor the Special
Servicer shall, except as expressly provided herein, assign or transfer any of
its rights, benefits or privileges hereunder (except for the assignment or other
transfer of the right to receive the Excess Servicing Strip) to any other
Person, or, except as provided in Sections 3.22 and 4.06, delegate to or
subcontract with, or authorize or appoint any other Person to perform any of the
duties, covenants or obligations to be performed by it hereunder. If, pursuant
to any provision hereof, the duties of the Master Servicer or the Special
Servicer are transferred to a successor thereto, the Master Servicing Fee or the
Special Servicing Fee, as the case may be, that accrues pursuant hereto from and
after the date of such transfer shall be payable to such successor.

     SECTION 6.05   Rights of Depositor and Trustee in Respect of Master
Servicer and the Special Servicer.

     The Master Servicer and the Special Servicer shall each afford the
Depositor, the Underwriters and the Trustee, upon reasonable notice, during
normal business hours access to all records maintained thereby in respect of its
rights and obligations hereunder and access to officers thereof responsible for
such obligations. Upon reasonable request, the Master Servicer and the Special
Servicer shall each furnish the Depositor, the Underwriters and the Trustee with
its most recent publicly available financial statements and such other
information as it possesses, and which it is not prohibited by applicable law or
contract from disclosing, regarding its business, affairs, property and
condition, financial or otherwise, except to the extent such information
constitutes proprietary information or is subject to a privilege under
applicable law. The Depositor may, but is not obligated to, enforce the
obligations of the Master Servicer and the Special Servicer hereunder and may,
but is not obligated to, perform, or cause a designee to perform, any defaulted
obligation of the Master Servicer or Special Servicer hereunder or exercise the
rights of the Master Servicer and the Special Servicer hereunder; provided,
however, that neither the Master Servicer nor the Special Servicer shall be
relieved of any of its obligations hereunder by virtue of such performance by
the Depositor or its designee and, further provided, that the Depositor may not
exercise any right pursuant to Section 7.01 to terminate the Master Servicer or
the Special Servicer as a party to this Agreement. The Depositor shall not have
any responsibility or liability for any action or failure to act by the Master
Servicer or the Special Servicer and is not obligated to supervise the
performance of the Master Servicer or the Special Servicer under this Agreement
or otherwise.

     SECTION 6.06   Depositor, Master Servicer and Special Servicer to Cooperate
with Trustee.

     The Depositor, the Master Servicer and the Special Servicer shall each (to
the extent not already furnished under this Agreement) furnish such reports,
certifications and information as are reasonably requested by the Trustee in
order to enable it to perform its duties hereunder.

     SECTION 6.07   Depositor, Special Servicer and Trustee to Cooperate with
Master Servicer.

     The Depositor, the Special Servicer and the Trustee shall each (to the

Servicer in order to enable it to perform its duties hereunder.

     SECTION 6.08   Depositor, Master Servicer and Trustee to Cooperate with

     SECTION 6.09   Designation of Special Servicer by the Controlling Class.

     (a) The Holder or Holders (or, in the case of Book-Entry Certificates, the
Certificate Owner or Certificate Owners) of the Certificates evidencing a
majority of the Voting Rights allocated to the Controlling Class may at any time
and from time to time designate a Person meeting the requirements set forth in
Section 6.04 (including, without limitation, Rating Agency confirmation) to
serve as Special Servicer hereunder and to replace any existing Special Servicer
or any Special Servicer that has resigned or otherwise ceased to serve as
Special Servicer; provided that such Holder or Holders (or such Certificate
Owner or Certificate Owners, as the case may be) shall pay all costs related to
the transfer of servicing if the Special Servicer is replaced other than due to
an Event of Default. Such Holder or Holders (or such Certificate Owner or
Certificate Owners, as the case may be) may also select a Controlling Class
Representative that may advise and direct the Special Servicer and whose
approval is required for certain actions, as described herein. Such Holder or
Holders (or such Certificate Owner or Certificate Owners, as the case may be)
shall so designate a Person to serve as replacement Special Servicer by the
delivery to the Trustee, the Master Servicer and the existing Special Servicer
of a written notice stating such designation. The Trustee shall, promptly after
receiving any such notice, deliver to the Rating Agencies an executed Notice and
Acknowledgment in the form attached hereto as Exhibit H-1. If such Holder or
Holders (or such Certificate Owner or Certificate Owners, as the case may be)
have not replaced the Special Servicer within 30 days of such Special Servicer's
resignation or the date such Special Servicer has ceased to serve in such
capacity, the Trustee shall designate a successor Special Servicer meeting the
requirements set forth in Section 6.04. Any designated Person shall become the
Special Servicer, subject to

                                      238
<PAGE>

satisfaction of the other conditions set forth below, on the date that the
Trustee shall have received written confirmation from all of the Rating Agencies
that the appointment of such Person will not result in the qualification,
downgrading or withdrawal of the rating or ratings assigned to one or more
Classes of the Certificates. The appointment of such designated Person as
Special Servicer shall also be subject to receipt by the Trustee of (1) an
Acknowledgment of Proposed Special Servicer in the form attached hereto as
Exhibit H-2, executed by the designated Person, and (2) an Opinion of Counsel
(at the expense of the Person designated to become the Special Servicer) to the
effect that the designation of such Person to serve as Special Servicer is in
compliance with this Section 6.09 and all other applicable provisions of this
Agreement, that upon the execution and delivery of the Acknowledgment of
Proposed Special Servicer the designated Person shall be bound by the terms of
this Agreement and that this Agreement shall be enforceable against the
designated Person in accordance with its terms. Any existing Special Servicer
shall be deemed to have resigned simultaneously with such designated Person's
becoming the Special Servicer hereunder; provided, however, that the resigning
Special Servicer shall continue to be entitled to receive all amounts accrued or
owing to it under this Agreement on or prior to the effective date of such
resignation, and it shall continue to be entitled to the benefits of Section
6.03 notwithstanding any such resignation. Such resigning Special Servicer shall
cooperate with the Trustee and the replacement Special Servicer in effecting the
termination of the resigning Special Servicer's responsibilities and rights
hereunder, including, without limitation, the transfer within two Business Days
to the replacement Special Servicer for administration by it of all cash amounts
that shall at the time be or should have been credited by the Special Servicer
to the Certificate Account or the REO Account or delivered to the Master
Servicer or that are thereafter received with respect to Specially Serviced
Mortgage Loans and REO Properties.

     (b) For so long as the Fairfield Commons Total Loan is serviced under this
Agreement and not the Series 2003-C5 Pooling and Servicing Agreement, the holder
of the Fairfield Commons Pari Passu Companion Loan shall have the right to
terminate and replace the Special Servicer (in respect of the Fairfield Commons
Total Loan only) upon an Event of Default by the Special Servicer under this
Agreement provided that such termination and replacement must comply with the
provisions of Section 6.09(a).

     SECTION 6.10   Master Servicer or Special Servicer as Owner of a
Certificate.

     The Master Servicer or an Affiliate of the Master Servicer or the Special
Servicer or an Affiliate of the Special Servicer may become the Holder of (or,
in the case of a Book-Entry Certificate, Certificate Owner with respect to) any
Certificate with (except as set forth in the definition of "Certificateholder")
the same rights it would have if it were not the Master Servicer or the Special
Servicer or an Affiliate thereof. If, at any time during which the Master
Servicer or the Special Servicer or an Affiliate of the Master Servicer or the
Special Servicer is the Holder of (or, in the case of a Book-Entry Certificate,
Certificate Owner with respect to) any Certificate, the Master Servicer or the
Special Servicer proposes to take action (including for this purpose, omitting
to take action) that (i) is not expressly prohibited by the terms hereof and
would not, in the Master Servicer's or the Special Servicer's good faith
judgment, violate the Servicing Standard, and (ii) if taken, might nonetheless,
in the Master Servicer's or the Special Servicer's reasonable, good faith
judgment, be considered by other Persons to violate the Servicing

                                      239
<PAGE>

Standard, then the Master Servicer or the Special Servicer may (but need not)
seek the approval of the Certificateholders to such action by delivering to the
Trustee a written notice that (a) states that it is delivered pursuant to this
Section 6.10, (b) identifies the Percentage Interest in each Class of
Certificates beneficially owned by the Master Servicer or the Special Servicer
or an Affiliate of the Master Servicer or the Special Servicer, and (c)
describes in reasonable detail the action that the Master Servicer or the
Special Servicer proposes to take. The Trustee, upon receipt of such notice,
shall forward it to the Certificateholders (other than the Master Servicer and
its Affiliates or the Special Servicer and its Affiliates, as appropriate),
together with such instructions for response as the Trustee shall reasonably
determine. If at any time Certificateholders holding greater than 50% of the
Voting Rights of all Certificateholders (calculated without regard to the
Certificates beneficially owned by the Master Servicer or its Affiliates or the
Special Servicer or its Affiliates) shall have failed to object in writing to
the proposal described in the written notice, and if the Master Servicer or the
Special Servicer shall act as proposed in the written notice within thirty (30)
days, such action shall be deemed to comply with, but not modify, the Servicing
Standard. The Trustee shall be entitled to reimbursement from the Master
Servicer or the Special Servicer, as applicable, for the reasonable expenses of
the Trustee incurred pursuant to this paragraph. It is not the intent of the
foregoing provision that the Master Servicer or the Special Servicer be
permitted to invoke the procedure set forth herein with respect to routine
servicing matters arising hereunder, but rather in the case of unusual
circumstances.

     SECTION 6.11   The Controlling Class Representative and the 77 West Wacker
Drive Operating Advisor.

     The Controlling Class Representative (and with respect to the 77 West
Wacker Drive Mortgage Loan, so long as a Control Change Event with respect to
the Class WW Principal Balance Certificates has not occurred, the 77 West Wacker
Drive Operating Advisor) will be entitled to advise the Special Servicer with
respect to the following actions of the Special Servicer, and notwithstanding
anything herein to the contrary except as necessary or advisable to avoid an
Adverse REMIC Event and except as set forth in, and in any event subject to, the
second paragraph of this Section 6.11, the Special Servicer will not be
permitted to take (or, with respect to Mortgage Loans with a Stated Principal
Balance equal to or greater than $2.5 million, permit the Master Servicer to
take) any of the following actions as to which the Controlling Class
Representative (or with respect to the 77 West Wacker Drive Mortgage Loan, the
77 West Wacker Drive Operating Advisor) has objected in writing within ten
Business Days of being notified thereof, which notification with respect to the
action described in clauses (vi) and (viii) below shall be copied by the Special
Servicer to the Master Servicer (provided that if such written objection has not
been received by the Special Servicer within such ten Business Day period, then
the Controlling Class Representative's approval will be deemed to have been
given):

          (i) any foreclosure upon or comparable conversion (which may include
     acquisitions of an REO Property) of the ownership of properties securing
     such of the Specially Serviced Mortgage Loans as come into and continue in

                                      240
<PAGE>

     payments or a modification consisting of the extension of the maturity date
     of a Mortgage Loan;

          (iii) any proposed sale of any Defaulted Mortgage Loan or any REO

     or pursuant to Section 3.18) for less than the outstanding principal
     balance of the related Defaulted Mortgage Loan or REO Loan, plus accrued
     interest (exclusive of Penalty Interest and Additional Interest), expenses
     and fees;

          (iv) any determination to bring an REO Property into compliance with

          (v) any release of material real property collateral for any Specially
     Serviced Mortgage Loan in the Trust Fund or for any non-Specially Serviced
     Mortgage Loan in the Trust Fund with a principal balance of $2.5 million or
     more, in either case, other than where the release is not conditioned on
     obtaining the consent of the lender or upon satisfaction of that Mortgage
     Loan;

          (vi) any acceptance of substitute or additional real property
     collateral for any Mortgage Loan in the Trust Fund (other than in
     circumstances involving a non- Specially Serviced Mortgage Loan with a
     principal balance of less than $2.5 million or where the acceptance of the
     substitute or additional collateral is not conditioned on obtaining the
     consent of the lender, in which event notice to the Controlling Class
     Representative (or in the case of the 77 West Wacker Drive Mortgage Loan,
     the 77 West Wacker Drive Operating Advisor) will be required);

          (vii) any waiver of a due-on-sale or due-on-encumbrance clause in any
     Specially Serviced Mortgage Loan in the Trust Fund or in any non-Specially
     Serviced Mortgage Loan in the Trust Fund with a principal balance of $2.5
     million or more;

          (viii) any releases of certain reserve funds or related letters of
     credit with respect to a Mortgaged Property securing a Mortgage Loan in the
     Trust Fund (other than in circumstances involving a non-Specially Serviced
     Mortgage Loan with a principal balance of less than $2.5 million or where
     the release is not conditioned on obtaining the consent of the lender, in
     which event, notice to the Controlling Class Representative (or in the case
     of the 77 West Wacker Drive Mortgage Loan, the 77 West Wacker Drive
     Operating Advisor) will be required);

          (ix) any termination or replacement, or consent to the termination or
     replacement, of a property manager with respect to any Mortgaged Property
     or any termination or change, or consent to the termination or change, of
     the franchise for any Mortgaged Property operated as a hospitality property
     (other than in circumstances involving a non-Specially Serviced Mortgage
     Loan with a principal balance of less than $2.5 million or where the action
     is not conditioned on obtaining the consent of the lender, in which case
     only prior notice to the Controlling Class Representative (or in the case
     of

                                      241
<PAGE>

     the 77 West Wacker Drive Mortgage Loan, the 77 West Wacker Drive Operating
     Advisor) will be required);

          (x) any determination that an insurance-related default is an
     Acceptable Insurance Default or that earthquake or terrorism insurance is
     not available at commercially reasonable rates; and

          (xi) with respect to any Mortgage Loan with a principal balance of
     $2.5 million or more, any waiver of insurance required under the related
     Mortgage Loan Documents (except as contemplated in clause (x) above);

provided, that with respect to performing Mortgage Loans, the ten Business Days
within which the Controlling Class Representative (or the 77 West Wacker Drive
Operating Advisor) must object to any such action shall not exceed the ten
Business Day period the Special Servicer has to object to the Master Servicer
taking such action as set forth in Sections 3.02, 3.08 and 3.20.

     In addition, the Controlling Class Representative (or with respect to the
77 West Wacker Drive Mortgage Loan, the 77 West Wacker Drive Operating Advisor)
may direct the Special Servicer to take, or to refrain from taking, any such
actions as the Controlling Class Representative (or with respect to the 77 West
Wacker Drive Mortgage Loan, the 77 West Wacker Drive Operating Advisor) may deem
advisable or as to which provision is otherwise made herein; provided that
notwithstanding anything herein to the contrary no advice, direction or
objection given or made by the Controlling Class Representative, (or with
respect to the 77 West Wacker Drive Mortgage Loan, the 77 West Wacker Drive
Operating Advisor) contemplated by the preceding paragraph, may require or cause
the Special Servicer to violate any applicable law, the terms of any Mortgage
Loan, any provision of this Agreement or the REMIC Provisions (and the Special
Servicer shall disregard any such direction or objection), including without
limitation the Special Servicer's obligation to act in accordance with the
Servicing Standard and the Mortgage Loan Documents, or expose the Depositor, the
Master Servicer, the Special Servicer, the Trust Fund, the Trustee, the Fiscal
Agent or any of their respective Affiliates, directors, officers, employees or
agents, to any material claim, suit or liability, or materially expand the scope
of the Master Servicer's or the Special Servicer's responsibilities hereunder or
cause the Master Servicer or the Special Servicer to act, or fail to act, in a
manner which violates the Servicing Standard.

     The Special Servicer shall not be obligated to seek approval from the
Controlling Class Representative (or, if applicable, the 77 West Wacker Drive
Operating Advisor) for any actions to be taken by the Special Servicer with
respect to any particular Specially Serviced Mortgage Loan if (i) the Special
Servicer has, as set forth in the first paragraph of this Section 6.11, notified
the Controlling Class Representative (or, if applicable, the 77 West Wacker
Drive Operating Advisor) in writing of various actions that the Special Servicer
proposes to take with respect to the work-out or liquidation of that Mortgage
Loan and (ii) for 60 days following the first such notice, the Controlling Class
Representative (or, if applicable, the 77 West Wacker Drive Operating Advisor)
has objected to all of the proposed actions and has failed to suggest any
alternative actions that the Special Servicer considers to be consistent with
the Servicing Standard.

                                      242
<PAGE>

     The Controlling Class Representative (and the 77 West Wacker Drive
Operating Advisor) will have no liability to the Certificateholders for any
action taken, or for refraining from the taking of any action, in good faith
pursuant to this Agreement, or for errors in judgment; provided, however, that
the Controlling Class Representative (and the 77 West Wacker Drive Operating
Advisor) will not be protected against any liability which would otherwise be
imposed by reason of willful misfeasance, bad faith or negligence in the
performance of duties or by reason of reckless disregard of obligations or
duties. By its acceptance of a Certificate, each Certificateholder confirms its
understanding that the Controlling Class Representative (and the 77 West Wacker
Drive Operating Advisor) may take actions that favor the interests of one or
more Classes of the Certificates over other Classes of the Certificates, and
that the Controlling Class Representative (and the 77 West Wacker Drive
Operating Advisor) may have special relationships and interests that conflict
with those of Holders of some Classes of the Certificates, that the Controlling
Class Representative may act solely in the interests of the Holders of the
Controlling Class (and that the 77 West Wacker Drive Operating Advisor may act
solely in the interests of the WW Controlling Holder), that the Controlling
Class Representative does not have any duties to the Holders of any Class of
Certificates other than the Controlling Class (and that the 77 West Wacker Drive
Operating Advisor does not have any duties to the Holders of any Class of
Certificates other than the Class that includes the WW Controlling Holder), that
the Controlling Class Representative (and the 77 West Wacker Drive Operating
Advisor) shall not be deemed to have been negligent or reckless, or to have
acted in bad faith or engaged in willful misfeasance, by reason of its having
acted solely in the interests of the Holders of the Controlling Class (or the WW
Controlling Holder, as applicable), and that the Controlling Class
Representative (and the 77 West Wacker Drive Operating Advisor) shall have no
liability whatsoever for having so acted, and no Certificateholder may take any
action whatsoever against the Controlling Class Representative (or the 77 West
Wacker Drive Operating Advisor) or any director, officer, employee, agent or
principal thereof for having so acted.

     If the Special Servicer intends to take any action that constitutes a
Specially Designated Servicing Action with respect to the Fairfield Commons
Total Loan, then it shall consult with the holder of the Fairfield Commons Pari
Passu Companion Loan as required under the related Fairfield Commons
Intercreditor Agreement.

     Section 6.12   Servicing of the Fairfield Commons Total Loan.

     (a) While the Fairfield Commons Total Loan is serviced under this Agreement
and the Fairfield Commons Pari Passu Companion Loan is not included in the
Series 2003-C5 Securitization, prior to taking or permitting any Specially
Designated Servicing Action with respect to the Fairfield Commons Total Loan,
the Special Servicer shall notify the holder of the Fairfield Commons Pari Passu
Companion Loan.

     The Special Servicer shall provide all information which the Special
Servicer considers to be material in connection with evaluating any such
Specially Designated Servicing Action to the holder of the Fairfield Commons
Pari Passu Companion Loan and the holder may contact the Special Servicer
regarding the proposed action. The Special Servicer shall have no obligation to
follow any advice of, or take any direction from, the holder of the Fairfield
Commons Pari Passu Companion Loan.

                                      243
<PAGE>

     While the Fairfield Commons Total Loan is serviced under this Agreement and
the Fairfield Commons Pari Passu Companion Loan is not included in the Series
2003-C5 Securitization, the Master Servicer or the Special Servicer, as
applicable, shall deliver to the holder of the Fairfield Commons Pari Passu
Companion Loan notice of any monetary or material non-monetary default with
respect to the Fairfield Commons Total Loan promptly after a servicing officer
of the Master Servicer or the Special Servicer, as applicable, becomes aware of
such default. Upon receipt of such notice, the holder of the Fairfield Commons
Pari Passu Companion Loan shall have the right to cure defaults, which (in the
case of monetary defaults) shall include the obligation to reimburse any related
Advances and interest thereon (each such cure, a "Cure Event") with respect to
the Fairfield Commons Total Loan within five Business Days of receipt of notice
with respect to a monetary default and within 30 days of receipt of notice with
respect to a material non-monetary default following the date of such notice
(such period, a "Cure Period" and, any payments made to effect any such cure,
"Cure Payments"); provided, however, that no single such Cure Event shall
continue for a period of more than 90 consecutive days (i.e., the related
Mortgagor must itself have cured the subject default, including through the
reimbursement of any related Cure Payment, within 90 days after the related Cure
Event) or, in the case of monetary defaults, three consecutive monthly payment
dates under the related Mortgage Loan Documents nor continue for 120 days or, in
the case of monetary defaults, four monthly payment dates under the related
Mortgage Loan Documents, in aggregate, in any 365-day period.

     (b) While the Fairfield Commons Total Loan is serviced under this Agreement
and the Fairfield Commons Pari Passu Companion Loan is not included in the
Series 2003-C5 Securitization, prior to entering into any modification of the
Fairfield Commons Total Loan that would materially affect the monetary terms of
the Fairfield Commons Total Loan, the Master Servicer or Special Servicer, as
applicable, shall provide the holder of the Fairfield Commons Pari Passu
Companion Loan with notice thereof and with all information that the Master
Servicer or Special Servicer, as applicable, considers material, but in any case
including a draft of the agreement, if any, that sets forth such proposed
modification. The holder of the Fairfield Commons Pari Passu Companion Loan
shall have the right to purchase the Fairfield Commons Pooled Mortgage Loan at a
price equal to the Purchase Price therefor by delivering notice to the Master
Servicer or Special Servicer, within five (5) Business Days of receipt of the
materials described in the preceding sentence, that it intends to exercise such
purchase option (such purchase option to terminate at the end of such 5-Business
Day period or upon receipt of notice by the Master Servicer or the Special
Servicer, as the case may be, that the Fairfield Commons Pooled Mortgage Loan
will be sold pursuant to Section 3.27(b)). In the event that it elects to
exercise such purchase option, the holder of the Fairfield Commons Pari Passu
Companion Loan shall deliver such Purchase Price (in respect of the Fairfield
Commons Pooled Mortgage Loan) to the Master Servicer within three (3) Business
Days of its exercise of such purchase option; and, upon its receipt of such
Purchase Price, the Master Servicer shall deposit the same in the Certificate
Account and shall notify the Trustee of such purchase. The purchase option set
forth in this paragraph shall be in addition to the purchase option set forth in
Section 6.12(c) hereof.

     (c) At any time that the Fairfield Commons Total Loan is serviced under
this Agreement and the Fairfield Commons Pari Passu Companion Loan is not
included in the Series 2003-C5 Securitization and the Fairfield Commons Pooled
Mortgage Loan is a Specially Serviced Loan (provided that the Fairfield Commons
Pooled Mortgage Loan is then in default or

                                      244
<PAGE>

default with respect thereto is reasonably foreseeable) and after expiration of
the applicable Cure Period without the occurrence of a Cure Event, the holder of
the Fairfield Commons Pari Passu Companion Loan shall have the right, by written
notice to the Master Servicer and the Special Servicer (a "Fairfield Commons
Pari Passu Companion Loan Purchase Notice") delivered at any time during the
45-day period commencing at the end of the applicable Cure Period, to purchase
the Fairfield Commons Pooled Mortgage Loan, in whole but not in part, at the
applicable Purchase Price. Upon the delivery of the Fairfield Commons Pari Passu
Companion Loan Purchase Notice to the Master Servicer and the Special Servicer,
the Special Servicer shall, on behalf of the Trust Fund, sell (and the holder of
the Fairfield Commons Pari Passu Companion Loan shall purchase) the Fairfield
Commons Pooled Mortgage Loan at the related Purchase Price, on a date (the
"Fairfield Commons Pari Passu Companion Loan Purchase Date") not less than five
(5) Business Days nor more than ten (10) Business Days after the date of the
related Fairfield Commons Pari Passu Companion Loan Purchase Notice, as shall be
established by the Special Servicer. The Purchase Price shall be calculated by
the Special Servicer, three (3) Business Days prior to the Fairfield Commons
Pari Passu Companion Loan Purchase Date and shall, absent manifest error, be
binding upon the holder of the Fairfield Commons Pari Passu Companion Loan.
Concurrently with the payment to the Trust of the related Purchase Price, the
Special Servicer shall direct the Trustee to execute at the sole cost and
expense of the holder of the Fairfield Commons Pari Passu Companion Loan in
favor of the holder of the Fairfield Commons Pari Passu Companion Loan
assignment documentation which will assign the Fairfield Commons Pooled Mortgage
Loan (and the related Mortgage Loan Documents) without recourse, representations
or warranties. The right of the holder of the Fairfield Commons Pari Passu
Companion Loan to purchase the Fairfield Commons Pooled Mortgage Loan shall
automatically terminate upon (a) the expiration of the 45-day period commencing
at the end of the applicable Cure Period, (b) 10 Business Days after delivery of
notification by the Special Servicer to the holder of the Fairfield Commons Pari
Passu Companion Loan of the Special Servicer's intention to sell the Fairfield
Commons Pooled Mortgage Loan pursuant to Section 3.18 (if it is a Defaulted
Mortgage Loan), (c) a foreclosure sale, sale by power of sale or delivery of a
deed in lieu of foreclosure with respect to the related Mortgaged Property or
(d) the Fairfield Commons Pooled Mortgage Loan ceasing to be a Specially
Serviced Mortgage Loan. Notwithstanding the foregoing, the right of the holder
of the Fairfield Commons Pari Passu Companion Loan to purchase the Fairfield
Commons Pooled Mortgage Loan shall automatically terminate upon any purchase of
such Mortgage Loan pursuant to Section 3.18.

     (d) The Master Servicer and the Special Servicer each shall provide to the
holder of the Fairfield Commons Pari Passu Companion Loan, with respect to such
Mortgage Loan or any related REO Property, the same reports, documents and other
information that the Master Servicer or the Special Servicer, as the case may
be, provides to the Trustee with respect to the Fairfield Commons Pooled
Mortgage Loan or any related REO Property, and on a concurrent basis. In
addition, the Trustee, the Master Servicer or the Special Servicer, as
applicable, shall, upon receipt of a written request, provide to the holder of
the Fairfield Commons Pari Passu Companion Loan (at such holder's cost) all
other reports, documents and information that such holder may reasonably request
with respect to the Fairfield Commons Pari Passu Companion Loan or any related
REO Property.

     (e) The rights of the holder of the Fairfield Commons Pari Passu Companion
Loan under this Section 6.12 shall be assignable to a designee thereof pursuant
to the Fairfield

                                      245

Commons Intercreditor Agreement; provided that the parties hereto are provided
with written notice by the assignor of such assignment and the contact details
(in a form substantially similar to that set out in Section 11.05) of the
assignee.

                                   ARTICLE VII

                                     DEFAULT

     SECTION 7.01   Events of Default.

     (a) "Event of Default", wherever used herein, means any one of the
following events:

          (i) any failure by the Master Servicer to deposit into the Certificate
     Account any amount required to be so deposited or remitted by it under this
     Agreement, which failure continues unremedied for two Business Days
     following the date on which the deposit or remittance was required to be
     made; or

          (ii) any failure by the Master Servicer to remit to the Trustee for
     deposit into the Distribution Account or the 77 West Wacker Drive
     Distribution Account, any amount required to be so deposited or remitted by
     it under this Agreement, which failure continues unremedied until 11:00
     a.m. New York City time on the Business Day following the date on which the
     remittance was required to be made, provided further, however, that to the
     extent the Master Servicer does not timely make such remittances, the
     Master Servicer shall pay the Trustee for the account of the Trustee
     interest on any amount not timely remitted at the Prime Rate from and
     including the applicable required remittance date to but not including the
     date such remittance is actually made; or

          (iii) any failure by the Special Servicer to deposit into the REO
     Account or to deposit into, or to remit to the Master Servicer for deposit
     into, the Certificate Account, any amount required to be so deposited or
     remitted under this Agreement provided, however, that the failure to
     deposit or remit such amount shall not be an Event of Default if such
     failure is remedied within one Business Day and in any event on or prior to
     the related Distribution Date; or

          (iv) any failure by the Master Servicer to timely make any Servicing
     Advance required to be made by it hereunder, which Servicing Advance
     remains unmade for a period of five Business Days following the date on
     which notice shall have been given to the Master Servicer, as the case may
     be, by the Trustee as provided in Section 3.03(c); or

          (v) any failure on the part of the Master Servicer or the Special
     Servicer duly to observe or perform in any material respect any other of
     the covenants or agreements on the part of the Master Servicer or the
     Special Servicer, as the case may be, contained in this Agreement which
     continues unremedied for a period of 30 days after the date on which
     written notice of such failure, requiring the same to be remedied, shall
     have been given to the Master Servicer or the Special Servicer, as the case
     may be, by any other party hereto or the Master Servicer or the Special
     Servicer, as the case may be

                                      246
<PAGE>

     (with a copy to each other party hereto), or by the Holders of Certificates
     entitled to at least 25% of the Voting Rights; or

          (vi) any breach on the part of the Master Servicer or the Special
     Servicer of any representation or warranty contained in this Agreement that
     materially and adversely affects the interests of any Class of
     Certificateholders and which continues unremedied for a period of 30 days
     after the date on which notice of such breach, requiring the same to be
     remedied, shall have been given to the Master Servicer or the Special
     Servicer, as the case may be, by any other party hereto or the Master
     Servicer or the Special Servicer, as the case may be (with a copy to each
     other party hereto), or by the Holders of Certificates entitled to at least
     25% of the Voting Rights, provided, however, that with respect to any
     failure which is not curable within such 30-day period, the Master Servicer
     or the Special Servicer, as the case may be, shall have an additional cure
     period of thirty (30) days so long as the Master Servicer or the Special
     Servicer, as the case may be, has commenced to cure within the initial
     30-day period and provided the Trustee with an Officer's Certificate
     certifying that it has diligently pursued, and is continuing to pursue, a
     full cure; or

          (vii) a decree or order of a court or agency or supervisory authority
     having jurisdiction in the premises in an involuntary case under any
     present or future federal or state bankruptcy, insolvency or similar law
     for the appointment of a conservator, receiver, liquidator, trustee or
     similar official in any bankruptcy, insolvency, readjustment of debt,
     marshaling of assets and liabilities or similar proceedings, or for the
     winding-up or liquidation of its affairs, shall have been entered against
     the Master Servicer or the Special Servicer and such decree or order shall
     have remained in force undischarged or unstayed for a period of 60 days,
     provided however, that, with respect to any such decree or order that
     cannot be discharged, dismissed or stayed within such 60-day period, the
     Master Servicer or the Special Servicer, as appropriate, will have an
     additional period of 30 days to effect such discharge, dismissal or stay so
     long as the Master Servicer or the Special Servicer, as appropriate, has
     commenced the appropriate proceedings to have such decree or order
     dismissed, discharged or stayed within the initial 60-day period and has
     diligently pursued, and is continuing to pursue, such discharge, dismissal
     or stay; or

          (viii) the Master Servicer or the Special Servicer shall consent to
     the appointment of a conservator, receiver, liquidator, trustee or similar
     official in any bankruptcy, insolvency, readjustment of debt, marshaling of
     assets and liabilities or similar proceedings of or relating to it or of or
     relating to all or substantially all of its property; or

          (ix) the Master Servicer or the Special Servicer shall admit in
     writing its inability to pay its debts generally as they become due, file a
     petition to take advantage of any applicable bankruptcy, insolvency or
     reorganization statute, make an assignment for the benefit of its
     creditors, voluntarily suspend payment of its obligations, or take any
     corporate action in furtherance of the foregoing; or

                                      247
<PAGE>

          (x) the Master Servicer is removed from S&P's approved Master Servicer
     list, or the Special Servicer is removed from S&P's approved Special
     Servicer list, and the Master Servicer or the Special Servicer, as the case
     may be, is not reinstated to that list within 60 days after its removal
     therefrom; or

          (xi) the Master Servicer ceases to be rated at least CMS3 by Fitch or
     the Special Servicer ceases to be rated at least CSS3 by Fitch, and such
     rating is not restored within 60 days after the subject downgrade or
     withdrawal.

     (b) If any Event of Default shall occur with respect to the Master Servicer
or the Special Servicer (in either case, for purposes of this Section 7.01(b),
the "Defaulting Party") and shall be continuing, then, and in each and every
such case, so long as such Event of Default shall not have been remedied, the
Trustee may, and at the written direction of the Controlling Class
Representative or the Holders of Certificates entitled to at least 25% of the
Voting Rights (and in the event of disagreement among such parties, the Holders
of the Certificates entitled to at least 25% of the Voting Rights shall
control), the Trustee shall, by notice in writing to the Defaulting Party (with
a copy of such notice to each other party hereto and the Rating Agencies),
terminate all of the rights and obligations (but not the liabilities for actions
and omissions occurring prior thereto) of the Defaulting Party under this
Agreement and in and to the Trust Fund, other than its rights as a
Certificateholder hereunder. From and after the receipt by the Defaulting Party
of such written notice of termination, all authority and power of the Defaulting
Party under this Agreement, whether with respect to the Certificates (other than
as a holder of any Certificate) or the Mortgage Loans or otherwise, shall pass
to and be vested in the Trustee pursuant to and under this Section, and, without
limitation, the Trustee is hereby authorized and empowered to execute and
deliver, on behalf of and at the expense of the Defaulting Party, as
attorney-in-fact or otherwise, any and all documents and other instruments, and
to do or accomplish all other acts or things necessary or appropriate to effect
the purposes of such notice of termination, whether to complete the transfer and
endorsement or assignment of the Mortgage Loans and related documents, or
otherwise. The Master Servicer and the Special Servicer each agree that, if it
is terminated pursuant to this Section 7.01(b), it shall promptly (and in any
event no later than 20 Business Days subsequent to its receipt of the notice of
termination) provide the Trustee with all documents and records, including those
in electronic form, requested thereby to enable the Trustee or a successor
Master Servicer or Special Servicer to assume the Master Servicer's or Special
Servicer's, as the case may be, functions hereunder, and shall cooperate with
the Trustee in effecting the termination of the Master Servicer's or Special
Servicer's, as the case may be, responsibilities and rights hereunder,
including, without limitation, (i) the transfer within 5 Business Days to the
Trustee or a successor Master or Special Servicer for administration by it of
all cash amounts that shall at the time be or should have been credited by the
Master Servicer to the Certificate Account, the Distribution Account, a
Servicing Account or a Reserve Account (if the Master Servicer is the Defaulting
Party) or that are thereafter received by or on behalf of it with respect to any
Mortgage Loan or (ii) the transfer within two Business Days to the Trustee or a
successor Special Servicer for administration by it of all cash amounts that
shall at the time be or should have been credited by the Special Servicer to the
REO Account, the Certificate Account, a Servicing Account or a Reserve Account
or delivered to the Master Servicer (if the Special Servicer is the Defaulting
Party) or that are thereafter received by or on behalf of it with respect to any
Mortgage Loan or REO Property (provided, however, that the Master Servicer and
the Special Servicer each shall, if terminated pursuant to this Section 7.01(b),
continue to be

                                      248
<PAGE>

entitled to receive all amounts accrued or owing to it under this Agreement on
or prior to the date of such termination, whether in respect of Advances or
otherwise, and it (and each of its shareholders, partners, members, managers,
directors, officers, employees, and agents) shall continue to be entitled to the
benefits of Section 6.03 notwithstanding any such termination). Any cost or
expenses in connection with any actions to be taken by the Master Servicer, the
Special Servicer or the Trustee pursuant to this paragraph shall be borne by the
Defaulting Party and if not paid by the Defaulting Party within 90 days after
the presentation of reasonable documentation of such costs and expenses, such
expense shall be reimbursed by the Trust Fund; provided, however, that the
Defaulting Party shall not thereby be relieved of its liability for such
expenses. If and to the extent that the Defaulting Party has not reimbursed such
costs and expenses, the Trustee shall have an affirmative obligation to take all
reasonable actions to collect such expenses on behalf of and at the expense of
the Trust Fund. For purposes of this Section 7.01 and of Section 7.03(b), the
Trustee shall not be deemed to have knowledge of an event which constitutes, or
which with the passage of time or notice, or both, would constitute an Event of
Default described in clauses (i)-(viii) of subsection (a) above unless a
Responsible Officer of the Trustee has actual knowledge thereof or unless notice
of any event which is in fact such an Event of Default is received by the
Trustee and such notice references the Certificates, the Trust Fund or this
Agreement.

     (c) If the Master Servicer is terminated solely due to an Event of Default
under Section 7.01(a)(ix) or (x) and if the terminated Master Servicer provides
the Trustee with the appropriate "request for proposal" materials within the ten
Business Days after such termination, then the Trustee shall promptly thereafter
(using such "request for proposal" materials provided by the terminated Master
Servicer) solicit good faith bids for the rights to master service the Mortgage
Loans under this Agreement from at least three (3) Persons qualified to act as
Master Servicer hereunder in accordance with Sections 6.02 and 7.02 (any such
Person so qualified, a "Qualified Bidder") or, if three (3) Qualified Bidders
cannot be located, then from as many Persons as the Trustee can determine are
Qualified Bidders; provided that, at the Trustee's request, the terminated
Master Servicer shall supply the Trustee with the names of Persons from whom to
solicit such bids; and provided, further, that the Trustee shall not be
responsible if less than three (3) or no Qualified Bidders submit bids for the
right to master service the Mortgage Loans under this Agreement. The bid
proposal shall require any Successful Bidder (as defined below), as a condition
of such bid, to enter into this Agreement as successor Master Servicer, and to
agree to be bound by the terms hereof, within 60 days after the termination of
Master Servicer. The Trustee shall solicit bids (i) on the basis of such
successor Master Servicer retaining all Sub-Servicers to continue the primary
servicing of the Mortgage Loans pursuant to the terms of the respective
Sub-Servicing Agreements and to enter into a Sub-Servicing Agreement with the
terminated Master Servicer to service each of the Mortgage Loans not subject to
a Sub-Servicing Agreement at a servicing fee rate per annum equal to the Master
Servicing Fee Rate minus 2.5 basis points per Mortgage Loan serviced (each, a
"Servicing-Retained Bid") and (ii) on the basis of terminating each
Sub-Servicing Agreement and Sub-Servicer that it is permitted to terminate in
accordance with Section 3.22 (each, a "Servicing-Released Bid"). The Trustee
shall select the Qualified Bidder with the highest cash Servicing-Retained Bid
(or, if none, the highest cash Servicing-Released Bid) (the "Successful Bidder")
to act as successor Master Servicer hereunder. The Trustee shall direct the
Successful Bidder to enter into this Agreement as successor Master Servicer
pursuant to the terms hereof (and, if the successful bid was a
Servicing-Retained Bid, to enter into a Sub-Servicing Agreement with the
terminated Master

                                      249
<PAGE>

Servicer as contemplated above and, at its option, to purchase the primary
servicing rights from any Sub-Servicer willing to sell such rights), no later
than 60 days after the termination of the Master Servicer.

     Upon the assignment and acceptance of the master servicing rights hereunder
to and by the Successful Bidder, the Trustee shall remit or cause to be remitted
(i) if the successful bid was a Servicing-Retained Bid, to the terminated Master
Servicer the amount of such cash bid received from the Successful Bidder (net of
"out-of-pocket" expenses incurred in connection with obtaining such bid and
transferring servicing) and (ii) if the successful bid was a Servicing-Released
Bid, to the Master Servicer and each terminated Sub-Servicer its respective Bid
Allocation.

     If the Successful Bidder has not entered into this Agreement as successor
Master Servicer within 60 days after the Trustee was appointed as successor
Master Servicer or no Successful Bidder was identified within such 60-day
period, the terminated Master Servicer shall reimburse the Trustee for all
reasonable "out-of-pocket" expenses incurred by the Trustee in connection with
such bid process and the Trustee shall have no further obligations under this
Section 7.01(c). The Trustee thereafter may act or may select a successor to act
as Master Servicer hereunder in accordance with Section 7.02.

     SECTION 7.02   Trustee to Act; Appointment of Successor.

     On and after the time the Master Servicer or the Special Servicer resigns
pursuant to Section 6.04 or receives a notice of termination pursuant to Section
7.01, the Trustee shall, unless a successor is appointed pursuant to Section
6.04, be the successor in all respects to the Master Servicer or the Special
Servicer, as the case may be, in its capacity as such under this Agreement and
the transactions set forth or provided for herein and shall have all (and the
former Master Servicer or the Special Servicer, as the case may be, shall cease
to have any) of the responsibilities, duties and liabilities (except as provided
in the next sentence) of the Master Servicer or the Special Servicer, as the
case may be, arising thereafter, including, without limitation, if the Master
Servicer is the resigning or terminated party, the Master Servicer's obligation
to make P&I Advances, the unmade P&I Advances that gave rise to such Event of
Default; provided, that if the Master Servicer is the resigning or terminated
party, and if after the Closing Date the Trustee is prohibited by law or
regulation from obligating itself to make P&I Advances (as evidenced by an
Opinion of Counsel delivered to the Depositor and the Rating Agencies) the
Trustee shall not be obligated to make such P&I Advances and provided, further,
that any failure to perform such duties or responsibilities caused by the Master
Servicer's or the Special Servicer's, as the case may be, failure to provide
information or monies required by Section 7.01 shall not be considered a default
by the Trustee hereunder. Notwithstanding anything contrary in this Agreement,
the Trustee shall in no event be held responsible or liable with respect to any
of the representations and warranties of the resigning or terminated party
(other than the Trustee) or for any losses incurred by such resigning or
terminated party pursuant to Section 3.06 hereunder nor shall the Trustee be
required to purchase any Mortgage Loan hereunder. As compensation therefor, the
Trustee shall be entitled to all fees and other compensation which the resigning
or terminated party would have been entitled to if the resigning or terminated
party had continued to act hereunder. Notwithstanding the above and subject to
its obligations under Section 3.22(d) and 7.01(b), the Trustee may, if it shall
be

                                      250
<PAGE>

unwilling in its sole discretion to so act as either Master Servicer or Special
Servicer, as the case may be, or shall, if it is unable to so act as either
Master Servicer or Special Servicer, as the case may be, or shall, if the
Trustee is not approved as a master servicer or a special servicer, as the case
may be, by any of the Rating Agencies or if either the Controlling Class
Representative or the Holders of Certificates entitled to at least 51% of the
Voting Rights so request in writing to the Trustee, promptly appoint, subject to
the approval of each of the Rating Agencies (as evidenced by written
confirmation therefrom to the effect that the appointment of such institution
would not cause the qualification, downgrading or withdrawal of the then current
rating on any Class of Certificates) or petition a court of competent
jurisdiction to appoint, any established mortgage loan servicing institution
that meets the requirements of Section 6.02 (including, without limitation,
rating agency confirmation), which institution shall, in the case of an
appointment by the Trustee, be reasonably acceptable to the Controlling Class
Representative; provided, however, that in the case of a resigning or terminated
Special Servicer, such appointment shall be subject to the rights of the Holders
of Certificates evidencing a majority of the Voting Rights allocated to the
Controlling Class to designate a successor pursuant to Section 6.09. Except with
respect to an appointment provided below, no appointment of a successor to the
Master Servicer or the Special Servicer hereunder shall be effective until the
assumption of the successor to such party of all its responsibilities, duties
and liabilities under this Agreement. Pending appointment of a successor to the
Master Servicer or the Special Servicer hereunder, the Trustee shall act in such
capacity as hereinabove provided. Notwithstanding the above, the Trustee shall,
if the Master Servicer is the resigning or terminated party and the Trustee is
prohibited by law or regulation from making P&I Advances, promptly appoint any
established mortgage loan servicing institution that has a net worth of not less
than $15,000,000 and is otherwise acceptable to each Rating Agency (as evidenced
by written confirmation therefrom to the effect that the appointment of such
institution would not cause the qualification, downgrading or withdrawal of the
then current rating on any Class of Certificates), as the successor to the
Master Servicer hereunder in the assumption of all or any part of the
responsibilities, duties or liabilities of the Master Servicer hereunder
(including, without limitation, the obligation to make P&I Advances), which
appointment will become effective immediately. In connection with any such
appointment and assumption described herein, the Trustee may make such
arrangements for the compensation of such successor out of payments on the
Mortgage Loans as it and such successor shall agree; provided, however, that no
such compensation shall be in excess of that permitted the resigning or
terminated party hereunder. Such successor and the other parties hereto shall
take such action, consistent with this Agreement, as shall be necessary to
effectuate any such succession.

     SECTION 7.03   Notification to Certificateholders.

     (a) Upon any resignation of the Master Servicer or the Special Servicer
pursuant to Section 6.04, any termination of the Master Servicer or the Special
Servicer pursuant to Section 7.01, any appointment of a successor to the Master
Servicer or the Special Servicer pursuant to Section 7.02 or the effectiveness
of any designation of a new Special Servicer pursuant to Section 6.09, the
Trustee shall give prompt written notice thereof to Certificateholders at their
respective addresses appearing in the Certificate Register.

     (b) Not later than the later of (i) 60 days after the occurrence of any
event which constitutes or, with notice or lapse of time or both, would
constitute an Event of Default and (ii)

                                      251
<PAGE>

five days after a Responsible Officer of the Trustee has notice of the
occurrence of such an event, the Trustee shall notify the Depositor and all
Certificateholders and the Rating Agencies of such occurrence, unless such
default shall have been cured.

     SECTION 7.04   Waiver of Events of Default.

     The Holders representing at least 66-2/3% of the Voting Rights allocated to
the Classes of Certificates affected by any Event of Default hereunder may waive
such Event of Default; provided, however, that an Event of Default under clauses
(i), (ii), (iii), (x), or (xi) of Section 7.01(a) may be waived only by all of
the Certificateholders of the affected Classes. Upon any such waiver of an Event
of Default, such Event of Default shall cease to exist and shall be deemed to
have been remedied for every purpose hereunder. No such waiver shall extend to
any subsequent or other Event of Default or impair any right consequent thereon
except to the extent expressly so waived. Notwithstanding any other provisions
of this Agreement, for purposes of waiving any Event of Default pursuant to this
Section 7.04, Certificates registered in the name of the Depositor or any
Affiliate of the Depositor shall be entitled to Voting Rights with respect to
the matters described above.

     SECTION 7.05   Additional Remedies of Trustee Upon Event of Default.

     During the continuance of any Event of Default, so long as such Event of
Default shall not have been remedied, the Trustee, in addition to the rights
specified in Section 7.01, shall have the right, in its own name and as trustee
of an express trust, to take all actions now or hereafter existing at law, in
equity or by statute to enforce its rights and remedies and to protect the
interests, and enforce the rights and remedies, of the Certificateholders
(including the institution and prosecution of all judicial, administrative and
other proceedings and the filings of proofs of claim and debt in connection
therewith). No remedy provided for by this Agreement shall be exclusive of any
other remedy, and each and every remedy shall be cumulative and in addition to
any other remedy, and no delay or omission to exercise any right or remedy shall
impair any such right or remedy or shall be deemed to be a waiver of any Event
of Default. Under no circumstances shall the rights provided to the Trustee
under this Section 7.05 be construed as a duty or obligation of the Trustee.

     SECTION 7.06   Replacement of Fairfield Commons Special Servicer.

     The Trustee may (and, at the direction of the Controlling Class
Representative or of Certificateholders representing at least 25% of the Voting
Rights, shall) upon an "Event of Default" by the Series 2003-C5 Special Servicer
under the Series 2003-C5 Pooling and Servicing Agreement consent to the
termination and replacement of, or exercise such rights as may be granted to it
under the Fairfield Commons Intercreditor Agreement and/or the Series 2003-C5
Pooling and Servicing Agreement to terminate and replace, the Series 2003-C5
Special Servicer; provided that the Trustee shall first obtain written
confirmation from each Rating Agency that its granting such consent or
exercising such rights shall not result in an Adverse Rating Event with respect
to any Class of rated Certificates. The Master Servicer shall notify the
Trustee, the Certificateholders, the Controlling Class Representative and the
Rating Agencies of any such "Event of Default" known to a Servicing Officer of
the Master Servicer in the same manner as it would notify such parties of an
Event of Default hereunder.

                                  ARTICLE VIII

                   CONCERNING THE TRUSTEE AND THE FISCAL AGENT

     SECTION 8.01   Duties of Trustee

     (a) The Trustee, prior to the occurrence of an Event of Default and after
the curing or waiver of all Events of Default which may have occurred,
undertakes to perform such duties and only such duties as are specifically set
forth in this Agreement. If an Event of Default occurs and is continuing, the
Trustee shall exercise such of the rights and powers vested in it by this
Agreement, and use the same degree of care and skill in their exercise as a
prudent man would exercise or use under the circumstances in the conduct of his
own affairs. Any permissive right of the Trustee contained in this Agreement
shall not be construed as a duty.

     (b) The Trustee, upon receipt of all resolutions, certificates, statements,
opinions, reports, documents, orders or other instruments furnished to the
Trustee which are specifically required to be furnished pursuant to any
provision of this Agreement (other than the Mortgage Files, the review of which
is specifically governed by the terms of Article II), shall examine them to
determine whether they conform to the requirements of this Agreement to the
extent specifically set forth herein. If any such instrument is found not to
conform to the requirements of this Agreement in a material manner, the Trustee
shall take such action as it deems appropriate to have the instrument corrected.
The Trustee shall not be responsible for the accuracy or content of any
resolution, certificate, statement, opinion, report, document, order or other
instrument furnished by the Depositor or the Master Servicer or the Special
Servicer, and accepted by the Trustee, in good faith, pursuant to this
Agreement.

     (c) No provision of this Agreement shall be construed to relieve the
Trustee from liability for its own negligent action, its own negligent failure
to act or its own misconduct; provided, however, that:

          (i) Prior to the occurrence of an Event of Default, and after the
     curing of all such Events of Default which may have occurred, the duties
     and obligations of the Trustee shall be determined solely by the express
     provisions of this Agreement, the Trustee shall not be liable except for
     the performance of such duties and obligations as are specifically set
     forth in this Agreement, no implied covenants or obligations shall be read
     into this Agreement against the Trustee and, in the absence of bad faith on
     the part of the Trustee, the Trustee may conclusively rely, as to the truth
     of the statements and the correctness of the opinions expressed therein,
     upon any certificates or opinions furnished to the Trustee and conforming
     to the requirements of this Agreement;

          (ii) The Trustee shall not be personally liable for an error of
     judgment made in good faith by a Responsible Officer or Responsible
     Officers of the Trustee, unless it shall be proved that the Trustee was
     negligent in ascertaining the pertinent facts if it was required to do so;

          (iii) The Trustee shall not be personally liable with respect to any
     action taken, suffered or omitted to be taken by it in good faith in
     accordance with the

                                      253
<PAGE>

     direction of Holders of Certificates entitled to at least 25% of the Voting
     Rights relating to the time, method and place of conducting any proceeding
     for any remedy available to the Trustee or exercising any trust or power
     conferred upon the Trustee, under this Agreement; and

          (iv) The protections, immunities and indemnities afforded to the
     Trustee hereunder shall also be available to it in its capacity as
     Authenticating Agent, Certificate Registrar, REMIC Administrator and
     Custodian.

     SECTION 8.02   Certain Matters Affecting Trustee.

     Except as otherwise provided in Section 8.01 and Article X:

     (a) the Trustee may rely upon and shall be protected in acting or
refraining from acting upon any resolution, Officers' Certificate, certificate
of auditors or any other certificate, statement, instrument, opinion, report,
notice, request, consent, order, appraisal, bond or other paper or document
reasonably believed by it to be genuine and to have been signed or presented by
the proper party or parties;

     (b) the Trustee may consult with counsel and the written advice of such
counsel or any Opinion of Counsel shall be full and complete authorization and
protection in respect of any action taken or suffered or omitted by it hereunder
in good faith and in accordance therewith;

     (c) The Trustee shall be under no obligation to exercise any of the trusts
or powers vested in it by this Agreement or to make any investigation of matters
arising hereunder or, except as provided in Section 10.01 or 10.02, to
institute, conduct or defend any litigation hereunder or in relation hereto at
the request, order or direction of any of the Certificateholders, pursuant to
the provisions of this Agreement, unless such Certificateholders shall have
offered to the Trustee reasonable security or indemnity against the costs,
expenses and liabilities which may be incurred therein or thereby; the Trustee,
shall not be required to expend or risk its own funds or otherwise incur any
financial liability in the performance of any of its duties hereunder, or in the
exercise of any of its rights or powers, if it shall have reasonable grounds for
believing that repayment of such funds or adequate indemnity against such risk
or liability is not reasonably assured to it; provided, however, that nothing
contained herein shall, relieve the Trustee of the obligation, upon the
occurrence of an Event of Default which has not been cured, to exercise such of
the rights and powers vested in it by this Agreement, and to use the same degree
of care and skill in their exercise as a prudent man would exercise or use under
the circumstances in the conduct of his own affairs;

     (d) The Trustee shall not be personally liable for any action reasonably
taken, suffered or omitted by it in good faith and believed by it to be
authorized or within the discretion or rights or powers conferred upon it by
this Agreement;

     (e) prior to the occurrence of an Event of Default hereunder and after the
curing of all Events of Default which may have occurred, the Trustee shall not
be bound to make any investigation into the facts or matters stated in any
resolution, certificate, statement, instrument, opinion, report, notice,
request, consent, order, approval, bond or other paper or document, unless
requested in writing to do so by Holders of Certificates entitled to at least
25% of the

                                      254
<PAGE>

Voting Rights; provided, however, that if the payment within a reasonable time
to the Trustee, of the costs, expenses or liabilities likely to be incurred by
it in the making of such investigation is, in the opinion of the Trustee, not
reasonably assured to the Trustee by the security afforded to it by the terms of
this Agreement, the Trustee, may require reasonable indemnity against such
expense or liability as a condition to taking any such action;

     (f) the Trustee may execute any of the trusts or powers hereunder or
perform any duties hereunder either directly or by or through agents or
attorneys; provided, however, that the Trustee, shall remain responsible for all
acts and omissions of such agents or attorneys within the scope of their
employment to the same extent as it is responsible for its own actions and
omissions hereunder;

     (g) The Trustee shall not be responsible for any act or omission of the
Master Servicer or the Special Servicer (unless the Trustee is acting as Master
Servicer or the Special Servicer) or the Depositor; and

     (h) neither the Trustee nor the Certificate Registrar shall have any
obligation or duty to monitor, determine or inquire as to compliance with any
restriction on transfer imposed under Article V under this Agreement or under
applicable law with respect to any transfer of any Certificate or any interest
therein, other than to require delivery of the certification(s) and/or Opinions
of Counsel described in said Article applicable with respect to changes in
registration of record ownership of Certificates in the Certificate Register and
to examine the same to determine substantial compliance with the express
requirements of this Agreement. The Trustee and Certificate Registrar shall have
no liability for transfers, including transfers made through the book entry
facilities of the Depository or between or among Depository Participants or
beneficial owners of the Certificates, made in violation of applicable
restrictions except for its failure to perform its express duties in connection
with changes in registration of record ownership in the Certificate Register.

     SECTION 8.03   Trustee and Fiscal Agent Not Liable for Validity or
Sufficiency of Certificates or Mortgage Loans.

     The recitals contained herein and in the Certificates, other than the
statements attributed to the Trustee in Article II and Section 8.15 and the
signature of the Certificate Registrar and the Authenticating Agent set forth on
each outstanding Certificate, shall be taken as the statements of the Depositor
or the Master Servicer or the Special Servicer, as the case may be, and neither
the Trustee nor the Fiscal Agent assumes any responsibility for their
correctness. Except as set forth in Section 8.15, the Trustee makes no
representations as to the validity or sufficiency of this Agreement or of any
Certificate (other than as to the signature of the Trustee set forth thereon) or
of any Mortgage Loan or related document. The Trustee and the Fiscal Agent shall
not be accountable for the use or application by the Depositor of any of the
Certificates issued to it or of the proceeds of such Certificates, or for the
use or application of any funds paid to the Depositor in respect of the
assignment of the Mortgage Loans to the Trust Fund, or any funds deposited in or
withdrawn from the Certificate Account or any other account by or on behalf of
the Depositor, the Master Servicer or the Special Servicer. The Trustee and the
Fiscal Agent shall not be responsible for the accuracy or content of any
resolution, certificate, statement, opinion, report, document, order or other
instrument furnished by the Depositor, the

                                      255
<PAGE>

Master Servicer or the Special Servicer, and accepted by the Trustee in good
faith, pursuant to this Agreement.

     SECTION 8.04   Trustee and Fiscal Agent May Own Certificates.

     The Trustee, the Fiscal Agent or any agent of the Trustee or the Fiscal
Agent, in its individual or any other capacity, may become the owner or pledgee
of Certificates with the same rights (except as otherwise provided in the
definition of "Certificateholder") it would have if it were not the Trustee or
such agent.

     SECTION 8.05   Fees and Expenses of Trustee; Indemnification of Trustee.

     (a) On each Distribution Date, the Trustee shall withdraw from the general
funds on deposit in the Distribution Account as provided in Section 3.05(b),
prior to any distributions to be made therefrom on such date, and pay to itself
all earned but unpaid Trustee Fees, as compensation for all services rendered by
the Trustee in the execution of the trusts hereby created and in the exercise
and performance of any of the powers and duties of the Trustee hereunder. The
Trustee Fee (which shall not be limited by any provision of law in regard to the
compensation of a trustee of an express trust) shall constitute the Trustee's
sole compensation for such services to be rendered by it.

     (b) The Trustee and any director, officer, employee, affiliate, agent or
"control" person within the meaning of the Securities Act of 1933, as amended,
of the Trustee shall be entitled to be indemnified for and held harmless by the
Trust Fund against any loss, liability or reasonable "out-of-pocket" expense
(including, without limitation, costs and expenses of litigation, and of
investigation, counsel fees, damages, judgments and amounts paid in settlement)
arising out of, or incurred in connection with this Agreement, the Mortgage
Loans or the Certificates or any act of the Master Servicer or the Special
Servicer taken on behalf of the Trustee as provided for herein, provided, that
such expense constitutes an "unanticipated expense" within the meaning of
Treasury Regulations Section 1.860G-1(b)(3)(ii); provided, further, that neither
the Trustee, nor any of the other above specified Persons shall be entitled to
indemnification pursuant to this Section 8.05(b) for (1) any liability
specifically required to be borne thereby pursuant to the terms hereof, or (2)
any loss, liability or expense incurred by reason of willful misfeasance, bad
faith or negligence in the performance of the Trustee's obligations and duties
hereunder, or by reason of its negligent disregard of such obligations and
duties, or as may arise from a breach of any representation, warranty or
covenant of the Trustee made herein. The provisions of this Section 8.05(b)
shall survive any resignation or removal of the Trustee and appointment of a
successor trustee.

     SECTION 8.06   Eligibility Requirements for Trustee.

     The Trustee hereunder shall at all times be an association, a bank, a trust
company or a corporation organized and doing business under the laws of the
United States of America or any State thereof or the District of Columbia,
authorized under such laws to exercise trust powers, having a combined capital
and surplus of at least $100,000,000 and subject to supervision or examination
by a federal or state banking authority. If such association, bank, trust
company or corporation publishes reports of condition at least annually,
pursuant to law or

                                      256
<PAGE>

to the requirements of the aforesaid supervising or examining authority, then
for the purposes of this Section the combined capital and surplus of such
association, bank, trust company or corporation shall be deemed to be its
combined capital and surplus as set forth in its most recent report of condition
so published. Subject to Section 8.18, the Trustee shall also be an entity with
a long term unsecured debt rating of at least "AA" by Fitch and S&P (determined
without regard to pluses or minuses) or has a fiscal agent with such ratings or
such other rating that shall not result in the qualification, downgrading or
withdrawal of the rating or ratings assigned to one or more Classes of the
Certificates by any Rating Agency as confirmed in writing. In case at any time
the Trustee shall cease to be eligible in accordance with the provisions of this
Section, the Trustee shall resign immediately in the manner and with the effect
specified in Section 8.07; provided, that if the Trustee shall cease to be so
eligible because its combined capital and surplus is no longer at least
$100,000,000 or its long-term unsecured debt rating no longer conforms to the
requirements of the immediately preceding sentence, and if the Trustee proposes
to the other parties hereto to enter into an agreement with (and reasonably
acceptable to) each of them, and if in light of such agreement the Trustee's
continuing to act in such capacity would not (as evidenced in writing by each
Rating Agency) cause any Rating Agency to qualify, downgrade or withdraw any
rating assigned thereby to any Class of Certificates, then upon the execution
and delivery of such agreement the Trustee shall not be required to resign, and
may continue in such capacity, for so long as none of the ratings assigned by
the Rating Agencies to the Certificates is qualified, downgraded or withdrawn
thereby. The corporation or association serving as Trustee may have normal
banking and trust relationships with the Depositor, the Master Servicer, the
Special Servicer and their respective Affiliates but, except to the extent
permitted or required by Section 7.02, shall not be an "Affiliate" (as such term
is defined in Section III of PTE 2000-58) of the Master Servicer, the Special
Servicer, any sub-servicer, the Depositor, or any obligor with respect to
Mortgage Loans constituting more than 5.0% of the aggregate authorized principal
balance of the Mortgage Loans as of the date of the initial issuances of the
Certificates or any "Affiliate" (as such term is defined in Section III of PTE
2000-58) of any such person.

     SECTION 8.07   Resignation and Removal of Trustee.

     (a) The Trustee may at any time resign and be discharged from the trusts
hereby created by giving written notice thereof to the Depositor, the Master
Servicer, the Special Servicer and to all Certificateholders at their respective
addresses set forth in the Certificate Register. Upon receiving such notice of
resignation, the Depositor shall promptly appoint a successor trustee meeting
the requirements in Section 8.06 and acceptable to the Rating Agencies by
written instrument, in duplicate, which instrument shall be delivered to the
resigning Trustee, and to the successor trustee. A copy of such instrument shall
be delivered to the Master Servicer, the Special Servicer and the
Certificateholders. If no successor trustee shall have been so appointed and
have accepted appointment within 30 days after the giving of such notice of
resignation, the resigning Trustee may petition any court of competent
jurisdiction for the appointment of a successor trustee.

     (b) If at any time the Trustee shall cease to be eligible in accordance
with the provisions of Section 8.06 and shall fail to resign after written
request therefor by the Depositor or the Master Servicer, or if at any time the
Trustee shall become incapable of acting, or shall be adjudged bankrupt or
insolvent, or a receiver of the Trustee of its property shall be appointed, or
any public officer shall take charge or control of the Trustee of its property
or affairs for the

                                      257
<PAGE>

purpose of rehabilitation, conservation or liquidation, or if the Trustee shall
fail (other than by reason of the failure of either the Master Servicer or the
Special Servicer to timely perform its obligations hereunder or as a result of
other circumstances beyond the Trustee's reasonable control), to timely deliver
any report to be delivered by the Trustee pursuant to Section 4.02 and such
failure shall continue unremedied for a period of five days, or if the Trustee
fails to make distributions required pursuant to Section 3.05(b), 4.01 or 9.01,
then the Depositor may remove the Trustee and appoint a successor trustee, if
necessary, acceptable to the Master Servicer and the Rating Agencies (as
evidenced by written confirmation therefrom to the effect that the appointment
of such institution would not cause the qualification, downgrading or withdrawal
of the then current rating on any Class of Certificates) by written instrument,
in duplicate, which instrument shall be delivered to the Trustee so removed and
to the successor Trustee. A copy of such instrument shall be delivered to the
Master Servicer, the Special Servicer and the Certificateholders by the
Depositor.

     (c) The Holders of Certificates entitled to at least 51% of the Voting
Rights may at any time remove the Trustee and appoint a successor trustee, if
necessary, by written instrument or instruments, in triplicate, signed by such
Holders or their attorneys-in-fact duly authorized, one complete set of which
instruments shall be delivered to the Master Servicer, one complete set to the
Trustee so removed and one complete set to the successor trustee so appointed. A
copy of such instrument shall be delivered to the Depositor, the Special
Servicer and the remaining Certificateholders by the successor so appointed. In
the event that the Trustee is terminated or removed pursuant to this Section
8.07, all of its rights and obligations under this Agreement and in and to the
Mortgage Loans shall be terminated, other than any rights or obligations that
accrued prior to the date of such termination or removal (including the right to
receive all fees, expenses and other amounts (including, without limitation, P&I
Advances and accrued interest thereon) accrued or owing to it under this
Agreement, with respect to periods prior to the date of such termination or
removal and no termination without cause shall be effective until the payment of
such amounts to the Trustee).

     (d) Any resignation or removal of the Trustee and appointment of a
successor trustee, pursuant to any of the provisions of this Section 8.07 shall
not become effective until acceptance of appointment by the successor trustee,
as provided in Section 8.08.

     SECTION 8.08   Successor Trustee.

     (a) Any successor trustee appointed as provided in Section 8.07 shall
execute, acknowledge and deliver to the Depositor, the Master Servicer, the
Special Servicer and to its predecessor trustee, an instrument accepting such
appointment hereunder, and thereupon the resignation or removal of the
predecessor trustee shall become effective and such successor trustee, without
any further act, deed or conveyance, shall become fully vested with all the
rights, powers, duties and obligations of its predecessor hereunder, with the
like effect as if originally named as trustee herein. The predecessor trustee
shall deliver to the successor trustee all Mortgage Files and related documents
and statements held by it hereunder (other than any Mortgage Files at the time
held on its behalf by a third-party Custodian, which Custodian shall become the
agent of the successor trustee), and the Depositor, the Master Servicer, the
Special Servicer and the predecessor trustee shall execute and deliver such
instruments and do such other things as may reasonably be required to more fully
and certainly vest and confirm in the

                                      258
<PAGE>

successor trustee all such rights, powers, duties and obligations, and to enable
the successor trustee to perform its obligations hereunder.

     (b) No successor trustee shall accept appointment as provided in this
Section 8.08, unless at the time of such acceptance such successor trustee shall
be eligible under the provisions of Section 8.06 and the Rating Agencies have
provided confirmation pursuant to such Section.

     (c) Upon acceptance of appointment by a successor trustee as provided in
this Section 8.08, such successor trustee shall mail notice of the succession of
such trustee hereunder to the Depositor and the Certificateholders.

     SECTION 8.09   Merger or Consolidation of Trustee.

     Any entity into which the Trustee may be merged or converted or with which
it may be consolidated or any entity resulting from any merger, conversion or
consolidation to which the Trustee shall be a party, or any entity succeeding to
the corporate trust business of the Trustee, shall be the successor of the
Trustee hereunder, provided such entity shall be eligible under the provisions
of Section 8.06 and the Rating Agencies have provided confirmation pursuant to
such Section, without the execution or filing of any paper or any further act on
the part of any of the parties hereto, anything herein to the contrary
notwithstanding.

     SECTION 8.10   Appointment of Co-Trustee or Separate Trustee.

     (a) Notwithstanding any other provisions hereof, at any time, for the
purpose of meeting any legal requirements of any jurisdiction in which any part
of the Trust Fund or property securing the same may at the time be located, the
Master Servicer and the Trustee acting jointly shall have the power and shall
execute and deliver all instruments to appoint one or more Persons approved by
the Trustee to act as co-trustee or co-trustees, jointly with the Trustee, or
separate trustee or separate trustees, of all or any part of the Trust Fund, and
to vest in such Person or Persons, in such capacity, such title to the Trust
Fund, or any part thereof, and, subject to the other provisions of this Section
8.10, such powers, duties, obligations, rights and trusts as the Master Servicer
and the Trustee may consider necessary or desirable. If the Master Servicer
shall not have joined in such appointment within 15 days after the receipt by it
of a request to do so, or in case an Event of Default in respect of the Master
Servicer shall have occurred and be continuing, the Trustee alone shall have the
power to make such appointment. No co-trustee or separate trustee hereunder
shall be required to meet the terms of eligibility as a successor trustee under
Section 8.06 hereunder and no notice to Holders of Certificates of the
appointment of co-trustee(s) or separate trustee(s) shall be required under
Section 8.08 hereof.

     (b) In the case of any appointment of a co-trustee or separate trustee
pursuant to this Section 8.10, all rights, powers, duties and obligations
conferred or imposed upon the Trustee shall be conferred or imposed upon and
exercised or performed by the Trustee and such separate trustee or co-trustee
jointly, except to the extent that under any law of any jurisdiction in which
any particular act or acts are to be performed (whether as Trustee hereunder or
as successor to the Master Servicer or the Special Servicer hereunder), the
Trustee shall be incompetent or unqualified to perform such act or acts, in
which event such rights, powers, duties

                                      259
<PAGE>

and obligations (including the holding of title to the Trust Fund or any portion
thereof in any such jurisdiction) shall be exercised and performed by such
separate trustee or co-trustee at the direction of the Trustee.

     (c) Any notice, request or other writing given to the Trustee shall be
deemed to have been given to each of the then separate trustees and co-trustees,
as effectively as if given to each of them. Every instrument appointing any
separate trustee or co-trustee shall refer to this Agreement and the conditions
of this Article VIII. Each separate trustee and co-trustee, upon its acceptance
of the trusts conferred, shall be vested with the estates or property specified
in its instrument of appointment, either jointly with the Trustee or separately,
as may be provided therein, subject to all the provisions of this Agreement,
specifically including every provision of this Agreement relating to the conduct
of, affecting the liability of, or affording protection to, the Trustee. Every
such instrument shall be filed with the Trustee.

     (d) Any separate trustee or co-trustee may, at any time, constitute the
Trustee, its agent or attorney-in-fact, with full power and authority, to the
extent not prohibited by law, to do any lawful act under or in respect of this
Agreement on its behalf and in its name. If any separate trustee or co-trustee
shall cease to exist, become incapable of acting, resign or be removed, all of
its estates, properties, rights, remedies and trusts shall vest in and be
exercised by the Trustee, to the extent permitted by law, without the
appointment of a new or successor trustee.

     (e) The appointment of a co-trustee or separate trustee under this Section
8.10 shall not relieve the Trustee of its duties and responsibilities hereunder.

     SECTION 8.11   Appointment of Custodians.

     The Trustee may appoint at the Trustee's expense one or more Custodians to
hold all or a portion of the Mortgage Files as agent for the Trustee. Each
Custodian shall be a depository institution supervised and regulated by a
federal or state banking authority, shall have combined capital and surplus of
at least $10,000,000, shall be qualified to do business in the jurisdiction in
which it holds any Mortgage File and shall not be the Depositor, any Mortgage
Loan Seller or any Affiliate of the Depositor or any Mortgage Loan Seller.
Neither the Master Servicer nor the Special Servicer shall have any duty to
verify that any such Custodian is qualified to act as such in accordance with
the preceding sentence. Any such appointment of a third party Custodian and the
acceptance thereof shall be pursuant to a written agreement, which written
agreement shall (i) be consistent with this Agreement in all material respects
and requires the Custodian to comply with this Agreement in all material
respects and requires the Custodian to comply with all of the applicable
conditions of this Agreement; (ii) provide that if the Trustee shall for any
reason no longer act in the capacity of Trustee hereunder (including, without
limitation, by reason of an Event of Default), the successor trustee or its
designee may thereupon assume all of the rights and, except to the extent such
obligations arose prior to the date of assumption, obligations of the Custodian
under such agreement or alternatively, may terminate such agreement without
cause and without payment of any penalty or termination fee; and (iii) not
permit the Custodian any rights of indemnification that may be satisfied out of
assets of the Trust Fund. The appointment of one or more Custodians shall not
relieve the Trustee from any of its obligations hereunder, and the Trustee shall
remain responsible and liable for all acts and

                                      260
<PAGE>

omissions of any Custodian. The initial Custodian shall be the Trustee.
Notwithstanding anything herein to the contrary, if the Trustee is no longer the
Custodian, any provision or requirement herein requiring notice or any
information or documentation to be provided to the Custodian shall be construed
to require that such notice, information or documents also be provided to the
Trustee. Any Custodian hereunder (other than the Trustee) shall at all times
maintain a fidelity bond and errors and omissions policy in amounts customary
for custodians performing duties similar to those set forth in this Agreement.

     SECTION 8.12   Appointment of Authenticating Agents.

     (a) The Trustee may at the Trustee's expense appoint one or more
Authenticating Agents, which shall be authorized to act on behalf of the Trustee
in authenticating Certificates. The Trustee shall cause any such Authenticating
Agent to execute and deliver to the Trustee an instrument in which such
Authenticating Agent shall agree to act in such capacity, in accordance with the
obligations and responsibilities herein. Each Authenticating Agent must be
organized and doing business under the laws of the United States of America or
of any State, authorized under such laws to do a trust business, have a combined
capital and surplus of at least $15,000,000, and be subject to supervision or
examination by federal or state authorities. Each Authenticating Agent shall be
subject to the same obligations, standard of care, protection and indemnities as
would be imposed on, or would protect, the Trustee hereunder. The appointment of
an Authenticating Agent shall not relieve the Trustee from any of its
obligations hereunder, and the Trustee shall remain responsible and liable for
all acts and omissions of the Authenticating Agent. If LaSalle Bank National
Association is removed as Trustee, then it shall be terminated as Authenticating
Agent. If the Authenticating Agent (other than LaSalle Bank National
Association) resigns or is terminated, the Trustee shall appoint a successor
Authenticating Agent which may be the Trustee or an Affiliate thereof. In the
absence of any other Person appointed in accordance herewith acting as
Authenticating Agent, the Trustee hereby agrees to act in such capacity in
accordance with the terms hereof. Notwithstanding anything herein to the
contrary, if the Trustee is no longer the Authenticating Agent, any provision or
requirement herein requiring notice or any information or documentation to be
provided to the Authenticating Agent shall be construed to require that such
notice, information or documentation also be provided to the Trustee.

     (b) Any Person into which any Authenticating Agent may be merged or
converted or with which it may be consolidated, or any Person resulting from any
merger, conversion, or consolidation to which any Authenticating Agent shall be
a party, or any Person succeeding to the corporate agency business of any
Authenticating Agent, shall continue to be the Authenticating Agent without the
execution or filing of any paper or any further act on the part of the Trustee
or the Authenticating Agent.

     (c) Any Authenticating Agent may at any time resign by giving at least 30
days' advance written notice of resignation to the Trustee, the Certificate
Registrar, the Master Servicer, the Special Servicer and the Depositor. The
Trustee may at any time terminate the agency of any Authenticating Agent by
giving written notice of termination to such Authenticating Agent, the Master
Servicer, the Certificate Registrar and the Depositor. Upon receiving a notice
of resignation or upon such a termination, or in case at any time any
Authenticating Agent shall cease to be eligible in accordance with the
provisions of this Section

                                      261
<PAGE>

8.12, the Trustee may appoint a successor Authenticating Agent, in which case
the Trustee shall given written notice of such appointment to the Master
Servicer, the Certificate Registrar and the Depositor and shall mail notice of
such appointment to all Holders of Certificates; provided, however, that no
successor Authenticating Agent shall be appointed unless eligible under the
provisions of this Section 8.12. Any successor Authenticating Agent upon
acceptance of its appointment hereunder shall become vested with all the rights,
powers, duties and responsibilities of its predecessor hereunder, with like
effect as if originally named as Authenticating Agent. No Authenticating Agent
shall have responsibility or liability for any action taken by it as such at the
direction of the Trustee.

     SECTION 8.13   Access to Certain Information.

     The Trustee shall afford to the Master Servicer, the Special Servicer, each
Rating Agency and the Depositor, any Certificateholder and to the OTS, the FDIC
and any other banking or insurance regulatory authority that may exercise
authority over any Certificateholder, access to any documentation regarding the
Mortgage Loans within its control that may be required to be provided by this
Agreement or by applicable law. Such access shall be afforded without charge but
only upon reasonable prior written request and during normal business hours at
the offices of the Trustee designated by it. Upon request and with the consent
of the Depositor and at the cost of the requesting Party, the Trustee shall
provide copies of such documentation to the Depositor, any Certificateholder and
to the OTS, the FDIC and any other bank or insurance regulatory authority that
may exercise authority over any Certificateholder.

     SECTION 8.14   Appointment of REMIC Administrators.

     (a) The Trustee may appoint at the Trustee's expense, one or more REMIC
Administrators, which shall be authorized to act on behalf of the Trustee in
performing the functions set forth in Sections 3.17, 10.01 and 10.02 herein. The
Trustee shall cause any such REMIC Administrator to execute and deliver to the
Trustee an instrument in which such REMIC Administrator shall agree to act in
such capacity, with the obligations and responsibilities herein. The appointment
of a REMIC Administrator shall not relieve the Trustee from any of its
obligations hereunder, and the Trustee shall remain responsible and liable for
all acts and omissions of the REMIC Administrator. Each REMIC Administrator must
be acceptable to the Trustee and must be organized and doing business under the
laws of the United States of America or of any State and be subject to
supervision or examination by federal or state authorities. In the absence of
any other Person appointed in accordance herewith acting as REMIC Administrator,
the Trustee hereby agrees to act in such capacity in accordance with the terms
hereof. If LaSalle Bank National Association is removed as Trustee, then LaSalle
Bank National Association shall be terminated as REMIC Administrator.

     (b) Any Person into which any REMIC Administrator may be merged or
converted or with which it may be consolidated, or any Person resulting from any
merger, conversion, or consolidation to which any REMIC Administrator shall be a
party, or any Person succeeding to the corporate agency business of any REMIC
Administrator, shall continue to be the REMIC Administrator without the
execution or filing of any paper or any further act on the part of the Trustee
or the REMIC Administrator.

                                      262
<PAGE>

     (c) Any REMIC Administrator may at any time resign by giving at least 30
days' advance written notice of resignation to the Trustee, the Certificate
Registrar, the Master Servicer, the Special Servicer and the Depositor. The
Trustee may at any time terminate the agency of any REMIC Administrator by
giving written notice of termination to such REMIC Administrator, the Master
Servicer, the Certificate Registrar and the Depositor. Upon receiving a notice
of resignation or upon such a termination, or in case at any time any REMIC
Administrator shall cease to be eligible in accordance with the provisions of
this Section 8.14, the Trustee may appoint a successor REMIC Administrator, in
which case the Trustee shall given written notice of such appointment to the
Master Servicer and the Depositor and shall mail notice of such appointment to
all Holders of Certificates; provided, however, that no successor REMIC
Administrator shall be appointed unless eligible under the provisions of this
Section 8.14. Any successor REMIC Administrator upon acceptance of its
appointment hereunder shall become vested with all the rights, powers, duties
and responsibilities of its predecessor hereunder, with like effect as if
originally named as REMIC Administrator. No REMIC Administrator shall have
responsibility or liability for any action taken by it as such at the direction
of the Trustee.

     SECTION 8.15   Representations, Warranties and Covenants of Trustee.

     The Trustee hereby represents and warrants to the Master Servicer, the
Special Servicer and the Depositor and for the benefit of the
Certificateholders, as of the Closing Date, that:

     (a) The Trustee is a national banking association duly organized, validly
existing and in good standing under the laws of the United States.

     (b) The execution and delivery of this Agreement by the Trustee, and the
performance and compliance with the terms of this Agreement by the Trustee, will
not violate the Trustee's organizational documents or constitute a default (or
an event which, with notice or lapse of time, or both, would constitute a
default) under, or result in a material breach of, any material agreement or
other material instrument to which it is a party or by which it is bound.

     (c) Except to the extent that the laws of certain jurisdictions in which
any part of the Trust Fund may be located require that a co-trustee or separate
trustee be appointed to act with respect to such property as contemplated by
Section 8.10, the Trustee has the full power and authority to carry on its
business as now being conducted and to enter into and consummate all
transactions contemplated by this Agreement, has duly authorized the execution,
delivery and performance of this Agreement, and has duly executed and delivered
this Agreement.

     (d) This Agreement, assuming due authorization, execution and delivery by
the other parties hereto, constitutes a valid, legal and binding obligation of
the Trustee, enforceable against the Trustee in accordance with the terms hereof
(including with respect to any advancing obligations hereunder), subject to (A)
applicable bankruptcy, insolvency, reorganization, moratorium and other laws
affecting the enforcement of creditors' rights generally and the rights of
creditors of banks, and (B) general principles of equity, regardless of whether
such enforcement is considered in a proceeding in equity or at law.

                                      263
<PAGE>

     (e) The Trustee is not in violation of, and its execution and delivery of
this Agreement and its performance and compliance with the terms of this
Agreement will not constitute a violation of, any law, any order or decree of
any court or arbiter, or any order, regulation or demand of any federal, state
or local governmental or regulatory authority, which violation, in the Trustee's
good faith and reasonable judgment, is likely to affect materially and adversely
the ability of the Trustee to perform its obligations under this Agreement.

     (f) No litigation is pending or, to the best of the Trustee's knowledge,
threatened against the Trustee that, if determined adversely to the Trustee,
would prohibit the Trustee from entering into this Agreement or, in the
Trustee's good faith and reasonable judgment, is likely to materially and
adversely affect the ability of the Trustee to perform its obligations under
this Agreement.

     (g) Any consent, approval, authorization or order of any court or
governmental agency or body required for the execution, delivery and performance
by the Trustee of or compliance by the Trustee with this Agreement or the
consummation of the transactions contemplated by this Agreement has been
obtained and is effective.

          (iv) within 90 days following the end of such fiscal year, prepare and
     properly file with the Securities and Exchange Commission, with respect to
     the Trust, an Annual Report on Form 10-K, which complies in all material
     respects with the requirements of the Exchange Act, the rules and
     regulations promulgated thereunder and applicable "no-action letters"
     issued by the Securities and Exchange Commission, which shall include as
     exhibits the Officer's Certificates and Accountant's Statements delivered
     pursuant to Section 3.13 and Section 3.14, respectively, with respect to
     the Master Servicer and the Special Servicer for such fiscal year, and
     which shall further include a certification in the form attached hereto as
     Exhibit O (a "Sarbanes-Oxley Certification") (or in such other form as
     required by the Sarbanes-Oxley Act of 2002, and the rules and regulations
     of the Commission promulgated thereunder (including any interpretations
     thereof by the commission's staff)), which Sarbanes-Oxley Certification
     shall be signed by an officer of the Depositor as contemplated by this
     Section 8.16;

provided that (x) the Trustee shall not have any responsibility to file any
items (other than those generated by it) that have not been received in a format
suitable for (or readily convertible to a format suitable for) electronic filing
via the EDGAR system (including "ASCII", "Microsoft Excel" (solely in the case
of reports from the Master Servicer or the Special Servicer pursuant to Section
3.12), "Microsoft Word" or another format reasonably acceptable to the Trustee)
and shall not have any responsibility to convert any such items to such format
(other than those items generated by it or readily convertible to such format)
and (y) the Depositor shall be responsible for preparing, executing and filing
(via the EDGAR system within 15 days following the Closing Date) a Current
Report on Form 8-K reporting the establishment of the Trust and whereby this
Agreement is filed as an exhibit. Each of the other parties to this Agreement
shall deliver to the Trustee in the format required for (or readily convertible
to a format suitable for) electronic filing via the EDGAR system (including
"ASCII", "Microsoft Excel" (solely in the case of reports from the Master
Servicer or the Special Servicer pursuant to Section 3.12), "Microsoft Word" or
another format reasonably acceptable to the Trustee) any and all items
contemplated to be filed with the Securities and Exchange Commission pursuant to
this Section 8.16(a).

     The Trustee shall have no liability to Certificateholders or the Trust with
respect to any failure to properly prepare or file with the Securities and
Exchange Commission any of the reports under the Exchange Act contemplated by
this Section 8.16(a) to the extent that such failure did not result from any
negligence, bad faith or willful misconduct on the part of the Trustee.

     (b) All Annual Reports on Form 10-K with respect to the Trust shall include
a Sarbanes-Oxley certification, in so far as it is required to be part of any
particular Annual Report on Form 10-K. An officer of the Depositor shall sign
the Sarbanes-Oxley Certification. The Depositor hereby grants to the Trustee a
limited power of attorney to execute and file such Annual Report on Form 10-K on
behalf of the Depositor, which power of attorney shall continue

                                      265
<PAGE>

until the earlier of (i) receipt by the Trustee from the Depositor of written
notice terminating such power of attorney or (ii) the termination of the Trust.
The Master Servicer, the Special Servicer and the Trustee (each, a "Performing
Party") shall provide to the Person who signs the Sarbanes-Oxley Certification
(the "Certifying Person"), and the Special Servicer shall also provide to the
Master Servicer, a certification (each, a "Performance Certification"), in the
form set forth on Exhibit P-1 hereto (with respect to the Master Servicer), in
the form set forth on Exhibit P-2 hereto (with respect to the Trustee), or in
the form set forth on Exhibit P-3 hereto (with respect to the Special Servicer's
certification to the Certifying Person of the Depositor) as applicable, on which
the Certifying Person, the Depositor (if the Certifying Person is an
individual), and the Depositor's partner, representative, Affiliate, member,
manager, director, officer, employee or agent (collectively with the Certifying
Person, "Certification Parties") can rely. Notwithstanding the foregoing,
nothing in this paragraph shall require any Performing Party to (i) certify or
verify the accurateness or completeness of any information provided to such
Performing Party by third parties, (ii) to certify information other than to
such Performing Party's knowledge and in accordance with such Performing Party's
responsibilities hereunder or under any other applicable servicing agreement or
(iii) with respect to completeness of information and reports, to certify
anything other than that all fields of information called for in written reports
prepared by such Performing Party have been completed except as they have been
left blank on their face. In addition, if directed by the Depositor, such
Performing Party (other than the Trustee) shall provide an identical
certification to Depositor's certified public accountants that such Performing
Party provided to its own certified public accountants to the extent such
certification relates to the performance of such Performing Party's duties
pursuant to this Agreement or a modified certificate limiting the certification
therein to the performance of such Performing Party's duties pursuant to this
Agreement. In the event any Performing Party is terminated or resigns pursuant
to the terms of this Agreement, such Performing Party shall provide a
Performance Certification to the Depositor pursuant to this Section 8.16 with
respect to the period of time such Performing Party was subject to this
Agreement.

     (c) At all times during the Trust's fiscal year 2003 (and, if as of the
beginning of any other fiscal year for the Trust, the Registered Certificates
are held (directly or, in the case of Registered Certificates held in book-entry
form, through the Depository) by at least 300 Holders and/or Depository
Participants having accounts with the Depository, or if reporting under the
Exchange Act is required during or for, as applicable, any other fiscal year
because the Trustee failed to make the requisite filing suspending such
reporting, at all times during such other fiscal year), the Trustee shall
monitor for and promptly notify the Depositor of the occurrence or existence of
any of the following matters of which a Responsible Officer of the Trustee has
actual knowledge:

          (i) any failure of the Trustee to make any monthly distributions to
     the Holders of any Class of Certificates, which failure is not otherwise
     reflected in the Certificateholder Reports filed with the Securities and
     Exchange Commission or has not otherwise been reported to the Depositor
     pursuant to any other Section of this Agreement;

          (ii) any acquisition or disposition by the Trust of a Mortgage Loan or
     an REO Property, which acquisition or disposition has not otherwise been
     reflected in the

                                      266
<PAGE>

     Certificateholder Reports filed with the Securities and Exchange Commission
     or has not otherwise been reported to the Depositor pursuant to any other
     section of this Agreement;

          (iii) any other acquisition or disposition by the Trust of a
     significant amount of assets (other than Permitted Investments, Mortgage
     Loans and REO Properties), other than in the normal course of business;

          (iv) any change in the fiscal year of the Trust;

          (v) any material legal proceedings, other than ordinary routine
     litigation incidental to the business of the Trust, to which the Trust (or
     any party to this Agreement on behalf of the Trust) is a party or of which
     any property included in the Trust Fund is subject, or any threat by a
     governmental authority to bring any such legal proceedings;

          (vi) any event of bankruptcy, insolvency, readjustment of debt,
     marshalling of assets and liabilities, or similar proceedings in respect of
     or pertaining to the Trust or any party to this Agreement, or any actions
     by or on behalf of the Trust or any party to this Agreement indicating its
     bankruptcy, insolvency or inability to pay its obligations; and

          (vii) any change in the rating or ratings assigned to any Class of
     Certificates not otherwise reflected in the Certificateholder Reports filed
     with the Securities and Exchange Commission;

provided that (x) the actual knowledge of a Responsible Officer of the Trustee
of any material legal proceedings of which property included in the Trust Fund
is subject or of any material legal proceedings threatened by a governmental
authority is limited to circumstances where it would be reasonable for the
Trustee to identify such property as an asset of, or as securing an asset of,
the Trust or such threatened proceedings as concerning the Trust and (y) no
Responsible Officer of the Trustee shall be deemed to have actual knowledge of
the matters described in clauses (vi) and (vii) of this Section 8.16(b) unless
such Responsible Officer was notified in writing.

     (d) If as of the beginning of any fiscal year for the Trust (other than
fiscal year 2003), the Registered Certificates are held (directly or, in the
case of Registered Certificates held in book-entry form, through the Depository)
by less than 300 Holders and/or Depository Participants having accounts with the
Depository, the Trustee shall, in accordance with the Exchange Act and the rules
and regulations promulgated thereunder, timely file a Form 15 with respect to
the Trust notifying the Securities and Exchange Commission of the suspension of
the reporting requirements under the Exchange Act.

     (e) Nothing contained in this Section 8.16 shall be construed to require
any party to this Agreement (other than the Depositor), or any of such party's
officers, to execute any Form 10-K or any Sarbanes-Oxley Certification. The
failure of any party to this Agreement, or any of such party's officers, to
execute any Form 10-K or any Sarbanes-Oxley Certification shall not be regarded
as a breach by such party of any of its obligations under this Agreement. The
Depositor, each Performing Party and the Trustee hereby agree to negotiate in
good faith with respect to compliance with any further guidance from the
Securities and Exchange Commission

                                      267
<PAGE>

or its staff relating to the execution of any Form 10-K and any Sarbanes-Oxley
Certification. In the event such parties agree on such matters, this Agreement
shall be amended to reflect such agreement pursuant to Section 11.01.

     (f) Each Performing Party shall indemnify and hold harmless each
Certification Party from and against any losses, damages, penalties, fines,
forfeitures, reasonable and necessary legal fees and related costs, judgments
and other costs and expenses incurred by such Certification Party arising out of
(i) an actual breach by the applicable Performing Party of its obligations under
this Section 8.16 or (ii) negligence, bad faith or willful misconduct on the
part of such Performing Party in the performance of its obligations otherwise
hereunder. A Performing Party shall have no obligation to indemnify any
Certification Party for an inaccuracy in the Performance Certification of any
other Performing Party.

     (g) If the Fairfield Commons Pari Passu Companion Loan is included in a
securitization trust and backs publicly offered securities, then each Performing
Party agrees that any Performance Certification delivered by it hereunder may be
delivered to, and relied upon by, any Person performing substantially the same
function with respect to such securitization trust as a Certification Party
hereunder, and such Performing Party shall indemnify and hold harmless any such
Person in respect of such securitization trust to whom any such Performance
Certification is delivered to the same extent that such Performing Party would
indemnify a Certification Party hereunder.

     (h) The respective parties hereto agree to cooperate with all reasonable
requests made by any Certifying Person in connection with such Person's attempt
to conduct any due diligence that such Person reasonably believes to be
appropriate in order to allow it to deliver any Sarbanes-Oxley Certification or
portion thereof with respect to the Trust.

     (i) Unless the other parties hereto receive written notice from the Trustee
to the contrary, the Trustee hereby certifies that it intends to file any Annual
Report on Form 10-K with respect to the Trust for any particular fiscal year on
the last Business Day that is not more than 90 days following the end of such
fiscal year. Unless an alternative time period is provided for in this
Agreement, the respective parties hereto shall deliver to the Trustee, at least
10 Business Days prior to the date on which the Trustee intends to file any
Annual Report on Form 10-K as contemplated by Section 8.16(a), any items
required to be delivered by such party that are to be an exhibit to such Annual
Report on Form 10-K. The Trustee hereby notifies the Master Servicer and the
Special Servicer that an Annual Report on Form 10-K shall be required to be
filed with respect to the Trust for 2003.

     SECTION 8.17   Maintenance of Mortgage File.

     Except for the release of items in the Mortgage File contemplated by this
Agreement, including, without limitation, as necessary for the enforcement of
the holder's rights and remedies under the related Mortgage Loan, the Trustee
covenants and agrees that it shall maintain each Mortgage File in the State of
Illinois, and that it shall not move any Mortgage File outside the State of
Illinois, other than as specifically provided for in this Agreement, unless it
shall first obtain and provide, at the expense of the Trustee, an Opinion of
Counsel to the Depositor and the Rating Agencies to the effect that the
Trustee's first priority interest in the

                                      268
<PAGE>

Mortgage Notes has been duly and fully perfected under the applicable laws and
regulations of such other jurisdiction.

     SECTION 8.18   Appointment of Fiscal Agent.

     (a) Insofar as the Trustee would not otherwise satisfy the rating
requirements of Section 8.06, the Trustee may appoint, at the Trustee's own
expense, a Fiscal Agent for purposes of making Advances hereunder that are
otherwise required to be made by the Trustee. The Fiscal Agent shall at all
times maintain a long-term unsecured debt rating of no less than "Aa3" from
Moody's and "AA-" from S&P and Fitch (or, in the case of any Rating Agency, such
lower rating as will not result in an Adverse Rating Event with respect to any
Class of Regular Certificates (as confirmed in writing to the Trustee and the
Depositor by such Rating Agency)).

     (b) To the extent that the Trustee is required, pursuant to the terms of
this Agreement, to make any Advance, whether as successor Master Servicer or
otherwise, and has failed to do so in accordance with the terms hereof, the
Fiscal Agent shall make such Advance when and as required by the terms of this
Agreement on behalf of the Trustee as if such Fiscal Agent were the Trustee
hereunder. To the extent that the Fiscal Agent makes an Advance pursuant to this
Section 8.18 or otherwise pursuant to this Agreement, the obligations of the
Trustee under this Agreement in respect of such Advance shall be satisfied.

     (c) Notwithstanding anything contained in this Agreement to the contrary,
the Fiscal Agent shall be entitled to all limitations on liability, rights of
reimbursement and indemnities to which the Trustee is entitled hereunder
(including, without limitation, pursuant to Sections 8.05(b)) as if it were the
Trustee, except that all fees of the Fiscal Agent shall be borne by the Trustee,
and neither the Trustee nor such Fiscal Agent shall be entitled to reimbursement
therefor from any of the Trust, the Depositor, the Master Servicer or the
Special Servicer.

     (d) The obligations of the Fiscal Agent set forth in this Section 8.18 or
otherwise pursuant to this Agreement shall exist only for so long as the Trustee
that appointed it shall act as Trustee hereunder and the Fiscal Agent shall
automatically be removed in the event of the resignation or removal of the
Trustee. The Fiscal Agent may resign or be removed by the Trustee only if and
when the existence of the Fiscal Agent is no longer necessary for such Trustee
to satisfy the eligibility requirements of Section 8.06; provided that the
Fiscal Agent shall be deemed to have resigned at such time as the Trustee that
appointed it resigns or is removed as Trustee hereunder (in which case the
responsibility for appointing a successor Fiscal Agent in accordance with this
Section 8.18(d) shall belong to the successor Trustee insofar as such
appointment is necessary for such successor Trustee to satisfy the eligibility
requirements of Section 8.06).

     (e) The Trustee shall promptly notify the other parties hereto and the
Certificateholders in writing of the appointment resignation or removal of the
Fiscal Agent.

     (f) The parties hereto hereby agree that ABN AMRO Bank N.V. shall be the
initial Fiscal Agent hereunder for the purposes of exercising and performing the
obligations and duties imposed upon the Fiscal Agent in this Agreement. The
Fiscal Agent undertakes to perform such duties and only such duties as are
specifically set forth in this Agreement.

                                   TERMINATION

     SECTION 9.01    Termination Upon Repurchase or Liquidation of All Mortgage
Loans.

     Subject to Section 9.02, the Trust Fund and the respective obligations and
responsibilities under this Agreement of the Depositor, the Master Servicer, the
Special Servicer and the Trustee (other than the obligations of the Trustee to
provide for and make payments to Certificateholders as hereafter set forth)
shall terminate upon payment (or provision for payment) (i) to the
Certificateholders of all amounts held by or on behalf of the Trustee and
required hereunder to be so paid on the Distribution Date following the earlier
to occur of (A) the purchase by the Master Servicer, the Special Servicer or the
Majority Subordinate Certificateholder of all Mortgage Loans and each REO
Property remaining in the Trust Fund at a price equal to (1) the aggregate
Purchase Price of all the Mortgage Loans included in both the Trust Fund, plus
(2) the appraised value of each REO Property, if any, included in 77 West Wacker
Drive Loan REMIC and REMIC I, such appraisal to be conducted by an Independent
Appraiser mutually agreed upon by the Master Servicer, the Special Servicer and
the Trustee, minus (3) if the purchaser is the Master Servicer, the aggregate
amount of unreimbursed Advances made by the Master Servicer, together with any
interest accrued and payable to the Master Servicer in respect of unreimbursed
Advances in accordance with Sections 3.03(d) and 4.03(d) and any unpaid Master
Servicing Fees remaining outstanding (which items shall be deemed to have been
paid or reimbursed to the Master Servicer in connection with such purchase), and
(B) the final payment or other liquidation (or any advance with respect thereto)
of the last Mortgage Loan or REO Property remaining in the Trust Fund, and (ii)
to the Trustee, the Master Servicer, the Special Servicer and the officers,
directors, employees and agents of each of them of all amounts which may have
become due and owing to any of them hereunder; provided, however, that in no
event shall the Trust Fund created hereby continue beyond the expiration of 21
years from the death of the last survivor of the descendants of Joseph P.
Kennedy, the late ambassador of the United States to the Court of St. James,
living on the date hereof.

     The obligations and responsibilities under this Agreement of the Depositor,
the Master Servicer, the Special Servicer, the Trustee, the Fiscal Agent and the
Companion Paying Agent shall terminate with respect to any Companion Loan to the
extent (i) its related AB Mortgage Loan has been paid in full or is no longer
part of the Trust Fund and (ii) no amounts payable by the related Companion
Holder to or for the benefit of the Trust Fund or any party hereto in accordance
with the related Intercreditor Agreement remain due and owing.

     The Master Servicer, the Special Servicer or the Majority Subordinate
Certificateholder may at its option elect to purchase all of the Mortgage Loans
and each REO Property remaining in the Trust Fund as contemplated by clause (i)
(A) of the second preceding paragraph by giving written notice to the other
parties hereto no later than 60 days prior to the anticipated date of purchase;
provided, however, that (i) the aggregate Stated Principal Balance of the
Mortgage Pool (including the 77 West Wacker Drive Non-Pooled Portion) at the
time of such election is less than 1.00% of the aggregate Cut-off Date Balances
of the Mortgage Loans (including the 77 West Wacker Drive Non-Pooled Portion) as
of the Closing Date, and (ii) the

                                      270
<PAGE>

Majority Subordinate Certificateholder shall not have the right to effect such a
purchase if, within 30 days following the Majority Subordinate
Certificateholder's delivery of a notice of election pursuant to this paragraph,
the Master Servicer or the Special Servicer shall give notice of its election to
purchase all of the Mortgage Loans and each REO Property remaining in the Trust
Fund and shall thereafter effect such purchase in accordance with the terms
hereof. The Special Servicer shall not have the right to effect such a purchase
if, within 30 days following the Special Servicer's delivery of a notice of
election pursuant to this paragraph, the Master Servicer shall give notice of
its election to purchase all of the Mortgage Loans and each REO Property
remaining in the Trust Fund and shall thereafter effect such purchase in
accordance with the terms hereof. If the Trust Fund is to be terminated in
connection with the Master Servicer's, the Special Servicer's or the Majority
Subordinate Certificateholder's purchase of all of the Mortgage Loans and each
REO Property remaining the Trust Fund, the Master Servicer, the Special Servicer
or the Majority Subordinate Certificateholder, as applicable, shall deliver to
the Trustee for deposit in the Distribution Account (or in the 77 West Wacker
Drive Distribution Account to the extent allocable to the 77 West Wacker Drive
Mortgage Loan) not later than the P&I Advance Date relating to the Distribution
Date on which the final distribution on the Certificates is to occur an amount
in immediately available funds equal to the above-described purchase price. In
addition, the Master Servicer shall transfer to the Distribution Account all
amounts required to be transferred thereto on such P&I Advance Date from the
Certificate Account pursuant to the first paragraph of Section 3.04(b) and to
the 77 West Wacker Drive Distribution Account all amounts required to be
transferred thereto on such P&I Advance date from the Certificate Account
pursuant to the first paragraph of Section 3.04(h), together with any other
amounts on deposit in the Certificate Account that would otherwise be held for
future distribution. Upon confirmation that such final deposit has been made,
the Trustee shall release or cause to be released to the Master Servicer, the
Special Servicer or the Majority Subordinate Certificateholder, as applicable,
the Mortgage Files for the remaining Mortgage Loans and shall execute all
assignments, endorsements and other instruments furnished to it by the Master
Servicer, the Special Servicer or the Majority Subordinate Certificateholder, as
applicable, as shall be necessary to effectuate transfer of the Mortgage Loans
and REO Properties to the Master Servicer, the Special Servicer or the Majority
Subordinate Certificateholder (or their respective designees), as applicable.

     Notice of any termination shall be given promptly by the Trustee by letter
to Certificateholders mailed (a) if such notice is given in connection with the
Master Servicer's, the Special Servicer's or the Majority Subordinate
Certificateholder's purchase of the Mortgage Loans and each REO Property
remaining the Trust Fund, not earlier than the 15th day and not later than the
25th day of the month next preceding the month of the final distribution on the
Certificates or (b) otherwise during the month of such final distribution on or
before the Determination Date in such month, in each case specifying (i) the
Distribution Date upon which the Trust Fund will terminate and final payment of
the Certificates will be made, (ii) the amount of any such final payment and
(iii) that the Record Date otherwise applicable to such Distribution Date is not
applicable, payments being made only upon presentation and surrender of the
Certificates at the offices of the Certificate Registrar or such other location
therein designated. The Trustee shall give such notice to the Master Servicer,
the Special Servicer and the Depositor at the time such notice is given to
Certificateholders.

                                      271
<PAGE>

     Upon presentation and surrender of the Certificates by the
Certificateholders on the final Distribution Date, the Trustee shall distribute
to each Certificateholder so presenting and surrendering its Certificates such
Certificateholder's Percentage Interest of that portion of the amounts then on
deposit in the Distribution Account or the 77 West Wacker Drive Distribution
Account, as applicable, that are allocable to payments on the Class of
Certificates so presented and surrendered. Amounts on deposit in the
Distribution Account as of the final Distribution Date, exclusive of any portion
thereof that would be payable to any Person in accordance with clauses (ii)
through (vi) of Section 3.05(b), including any portion thereof that represents
Prepayment Premiums and Yield Maintenance Charges, shall be (i) deemed
distributed in respect of the REMIC I Regular Interests and distributed to the
Class R-I Certificates in respect of the REMIC I Residual Interest in accordance
with Section 4.01(b) and Section 4.01(h) and (ii) distributed to the REMIC II
Certificates (other than the Class WW-1, Class WW-2, Class WW-3 and Class WW-X
Certificates) in the order of priority set forth in Section 4.01(a) and Section
4.01(b), in each case, to the extent of remaining available funds; provided that
any such amounts on deposit in the Distribution Account that relate to the 77
West Wacker Drive Pooled Portion shall be first applied in the same manner as
amounts on deposit in the 77 West Wacker Drive Distribution Account. Amounts on
deposit in the 77 West Wacker Drive Distribution Account as of the final
Distribution Date, exclusive of any portion thereof that would be payable to any
Person in accordance with clauses (ii) through (vi) of Section 3.05(f),
including any portion thereof that represents Prepayment Premiums and Yield
Maintenance Charges, shall be (i) deemed to have first been distributed from 77
West Wacker Drive Loan REMIC to REMIC I and then to REMIC II as of the Final
Distribution Date and (ii) distributed to the 77 West Wacker Drive Pooled
Portion or the Class WW Certificates in the order of priority set forth in
Section 4.01(k) or (l), as applicable, and Section 4.01(b), in each case, to the
extent of remaining available funds.

     On or after the Final Distribution Date, upon presentation and surrender of
the Class Z-I Certificates, the Trustee shall distribute to the Class Z-I
Certificateholders any amount then on deposit in the Additional Interest Account
that was paid on a Merrill Mortgage Loan. On or after the Final Distribution
Date, upon presentation and surrender of the Class Z-II Certificates, the
Trustee shall distribute to the Class Z-II Certificateholders any amount then on
deposit in the Additional Interest Account that was paid on a KeyBank Mortgage
Loan.

     Any funds not distributed to any Holder or Holders of Certificates of such
Class on such Distribution Date because of the failure of such Holder or Holders
to tender their Certificates shall, on such date, be set aside and held
uninvested in trust and credited to the account or accounts of the appropriate
non-tendering Holder or Holders. If any Certificates as to which notice has been
given pursuant to this Section 9.01 shall not have been surrendered for
cancellation within six months after the time specified in such notice, the
Trustee shall mail a second notice to the remaining non-tendering
Certificateholders to surrender their Certificates for cancellation in order to
receive the final distribution with respect thereto. If within one year after
the second notice all such Certificates shall not have been surrendered for
cancellation, the Trustee, directly or through an agent, shall take such
reasonable steps to contact the remaining non-tendering Certificateholders
concerning the surrender of their Certificates as it shall deem appropriate, and
shall deal with all such unclaimed amounts in accordance with applicable law.
The costs and expenses of holding such funds in trust and of contacting such
Certificateholders following the first anniversary of the delivery of such
second notice to the non-tendering Certificateholders shall be paid out of such
funds. No interest shall accrue or be payable to any former Holder on any amount
held in trust hereunder.

     SECTION 9.02   Additional Termination Requirements.

     (a) If the Master Servicer, the Special Servicer or the Majority
Subordinate Certificateholder purchase all of the Mortgage Loans and each REO
Property remaining in the Trust Fund as provided in Section 9.01, the Trust Fund
(and, accordingly, 77 West Wacker Drive Loan REMIC, REMIC I and REMIC II) shall
be terminated in accordance with the following additional requirements, unless
the Person effecting the purchase obtains at its own expense and delivers to the
Trustee, an Opinion of Counsel, addressed to the Trustee, to the effect that the
failure of the Trust Fund to comply with the requirements of this Section 9.02
will not result in the imposition of taxes on "prohibited transactions" of 77
West Wacker Drive Loan REMIC,

                                      272

     period in a statement attached to the final Tax Return for each of 77 West
     Wacker Drive Loan REMIC, REMIC I and REMIC II pursuant to Treasury
     Regulations Section 1.860F-1;

          (ii) during such 90-day liquidation period and at or prior to the time
     of making of the final payment on the Certificates, the Trustee shall sell
     all of the assets of 77 West Wacker Drive Loan REMIC and REMIC I to the
     Master Servicer, the Special Servicer or the Majority Subordinate
     Certificateholder, as applicable, for cash; and

          (iii) at the time of the making of the final payment on the

     Section 9.01 all cash on hand (other than cash retained to meet claims),
     and each of 77 West Wacker Drive Loan REMIC, REMIC I and REMIC II shall
     terminate at that time.

     (b) By their acceptance of Certificates, the Holders thereof hereby agree
to authorize the Trustee to specify the 90-day liquidation period for each of
REMIC I and REMIC II, which authorization shall be binding upon all successor

Code or the tax on contributions to a REMIC set forth in Section 860G(d) of the

Administrator has obtained or received an Opinion of Counsel (at the expense of
the party requesting such action or at the expense of the Trust Fund if the
REMIC Administrator seeks to take such action or to refrain from acting for the
benefit of the Certificateholders) to the effect that the contemplated action

writing that either the Master Servicer or the Special Servicer has received or

Adverse REMIC Event to occur. Neither the Master Servicer nor the Special
Servicer shall take any such action or cause either 77 West Wacker Drive Loan
REMIC, REMIC I or REMIC II to take any such action as to which the REMIC
Administrator has advised it in writing that an Adverse REMIC Event could occur,

accordance with the written instructions of the REMIC Administrator. The REMIC
Administrator may consult with counsel to make such written advice, and the cost
of same shall be borne by the party seeking to take the action not expressly
permitted by this Agreement, but in no event at the cost or expense of the Trust
Fund, the Trustee or the REMIC Administrator. At all times as may be required by
the Code, the REMIC Administrator shall make reasonable efforts to ensure that
substantially all of the assets of each of 77 West Wacker Drive Loan REMIC,
REMIC I and REMIC II will consist of "qualified mortgages" as defined in Section
860G(a)(3) of the Code and "permitted investments" as defined in Section

     (i) If any tax is imposed on any of 77 West Wacker Drive Loan REMIC, REMIC

3.17(a)), such tax, together with all incidental costs and expenses (including,
without limitation, penalties and reasonable attorneys' fees), shall be charged
to and paid by: (i) the REMIC Administrator, if such tax arises out of or
results from a breach by the REMIC Administrator of any of its obligations under
this Article X provided that no liability shall be imposed upon the REMIC
Administrator under this Clause if another party has responsibility for payment
of such tax under Clauses (iii) or (v) of this Section; (ii) the Special
Servicer, if such tax arises out of or results from a breach by the Special
Servicer of any of its obligations under Article III or this Article X; (iii)
the Master Servicer, if such tax arises out of or results from a breach by the
Master Servicer of any of its obligations under Article III or this Article X;
(iv) the Trustee, if such tax arises out of or results from a breach by the
Trustee, of any of its respective obligations under Article IV, Article VIII or
this Article X; (v) the applicable Mortgage Loan Seller, if such tax was imposed
due to the fact that any of the Mortgage Loans did not, at the time of their
transfer to 77 West Wacker Drive Loan REMIC or REMIC I, as applicable,
constitute a "qualified mortgage" as defined in Section 860G(a)(3) of the Code;
or (vi) the Trust Fund, excluding the portion thereof constituting the Grantor
Trust, in all other instances. Any tax permitted to be incurred by the Special
Servicer pursuant to Section 3.17(a) shall be charged to and paid by the Trust
Fund. Any such amounts payable by the Trust Fund shall be paid by the Trustee
upon the written direction of the REMIC Administrator out of amounts on deposit

the Special Servicer shall accept any contributions of assets to 77 West Wacker
Drive Loan REMIC, REMIC I or REMIC II unless it shall have received an Opinion
of Counsel (at the expense of the party seeking to cause such contribution and
in no event at the expense of the Trust Fund, the Trustee) to the effect that
the inclusion of such assets in such REMIC will not cause: (i) such REMIC to
fail to qualify as a REMIC at any time that any Certificates are outstanding; or
(ii) the

                                      276
<PAGE>

imposition of any tax on such REMIC under the REMIC Provisions or other
applicable provisions of federal, state and local law or ordinances.

     (l) None of the Trustee, the Master Servicer, the Special Servicer shall
consent to or, to the extent it is within the control of such Person, permit:

REMIC, REMIC I or REMIC II, (C) the termination of 77 West Wacker Drive Loan
REMIC, REMIC I and REMIC II pursuant to Article IX of this Agreement, or (D) a

Mortgage Loan, (2) a Qualified Substitute Mortgage Loan pursuant to Article II
hereof and (3) Permitted Investments acquired in connection with the investment
of funds in the Certificate Account, the Distribution Account or the REO
Account); in any event unless it has received an Opinion of Counsel (at the
expense of the party seeking to cause such sale, disposition, or acquisition but
in no event at the expense of the Trust Fund, the Trustee) to the effect that
such sale, disposition, or acquisition will not cause: (x) 77 West Wacker Drive
Loan REMIC, REMIC I or REMIC II to fail to qualify as a REMIC at any time that
any Certificates are outstanding; or (y) the imposition of any tax on 77 West
Wacker Drive Loan REMIC, REMIC I or REMIC II under the REMIC Provisions or other
applicable provisions of federal, state and local law or ordinances.

     (m) Except as permitted by Section 3.17(a), none of the Trustee, the Master
Servicer and the Special Servicer shall enter into any arrangement by which 77
West Wacker Drive Loan REMIC, REMIC I or REMIC II will receive a fee or other
compensation for services nor permit 77 West Wacker Drive Loan REMIC, REMIC I or
REMIC II to receive any income from assets other than "qualified mortgages" as
defined in Section 860G(a)(3) of the Code or "permitted investments" as defined
in Section 860G(a)(5) of the Code.

     SECTION 10.02  Grantor Trust Administration.

     (a) The REMIC Administrator shall treat the Grantor Trust, for tax return
preparation purposes, as a grantor trust under the Code and shall treat the
Additional Interest, the Additional Interest Account and amounts held from time
to time in the Additional Interest Account that represent Additional Interest as
separate assets of the Grantor Trust, and not of 77 West Wacker Drive Loan
REMIC, REMIC I or REMIC II, as permitted by Treasury Regulations Section
1.860G-2(i)(1). The Class Z-I Certificates are hereby designated as representing
an undivided beneficial interest in Additional Interest payable on Merrill
Mortgage Loans and proceeds thereof. The Class Z-II Certificates are hereby
designated as representing an undivided beneficial interest in Additional
Interest payable on KeyBank Mortgage Loans and proceeds thereof.

     (b) The REMIC Administrator shall pay out of its own funds any and all
routine tax administration expenses of the Trust Fund incurred with respect to
the Grantor Trust (but not

                                      277
<PAGE>

including any professional fees or expenses related to audits or any
administrative or judicial proceedings with respect to the Trust Fund that
involve the Internal Revenue Service or state tax authorities which

Administrator from the Trust Fund unless otherwise provided in Section 10.02(e)
or 10.02(f)).

     (c) The REMIC Administrator shall prepare, cause the Trustee to sign and
file when due all of the Tax Returns in respect of the Grantor Trust. The
expenses of preparing and filing such returns shall be borne by the REMIC

hereto shall provide on a timely basis to the REMIC Administrator or its
designee such information with respect to the Grantor Trust as is in its
possession and reasonably requested by the REMIC Administrator to enable it to
perform its obligations under this Section 10.02. Without limiting the
generality of the foregoing, the Depositor, within ten days following the REMIC
Administrator's request therefor, shall provide in writing to the REMIC
Administrator such information as is reasonably requested by the REMIC
Administrator for tax purposes, and the REMIC Administrator's duty to perform
its reporting and other tax compliance obligations under this Section 10.02
shall be subject to the condition that it receives from the Depositor such
information possessed by the Depositor that is necessary to permit the REMIC
Administrator to perform such obligations.

     (d) The REMIC Administrator shall furnish or cause to be furnished to the
Class Z-I and Class Z-II Certificateholders on the cash or accrual method of
accounting, as applicable, such information as to their respective portions of
the income and expenses of the Grantor Trust as may be required under the Code,

compliance duties that are required in respect thereof under the Code, the
Grantor Trust Provisions or other compliance guidance issued by the Internal

     (e) The REMIC Administrator shall perform its duties hereunder so as to
maintain the status of the Grantor Trust as a grantor trust under the Grantor
Trust Provisions (and the Trustee, the Master Servicer and the Special Servicer
shall assist the REMIC Administrator to the extent reasonably requested by the
REMIC Administrator and to the extent of information within the Trustee's, the
Master Servicer's or the Special Servicer's possession or control). None of the
REMIC Administrator, Master Servicer, the Special Servicer or the Trustee shall
knowingly take (or cause the Grantor Trust to take) any action or fail to take
(or fail to cause to be taken) any action that, under the Grantor Trust
Provisions, if taken or not taken, as the case may be, could endanger the status
of the Grantor Trust as a grantor trust under the Grantor Trust Provisions (any
such endangerment of grantor trust status, an "Adverse Grantor Trust Event"),
unless the REMIC Administrator has obtained or received an Opinion of Counsel
(at the expense of the party requesting such action or at the expense of the
Trust Fund if the REMIC Administrator seeks to take such action or to refrain
from taking any action for the benefit of the Certificateholders) to the effect
that the contemplated action will not result in an Adverse Grantor Trust Event.
None of the other parties hereto shall take any action or fail to take any
action (whether or not authorized hereunder) as to which the REMIC Administrator
has advised it in writing that the REMIC Administrator has received or obtained
an Opinion of Counsel to the effect that an Adverse Grantor Trust Event could
result from such action or failure to act. In addition, prior to taking any
action with respect to the Grantor Trust, or causing the Trust Fund to take any
action, that is not expressly permitted under the terms of this Agreement, the
Master

                                      278
<PAGE>

Servicer and the Special Servicer shall consult with the REMIC Administrator or
its designee, in writing, with respect to whether such action could cause an
Adverse Grantor Trust Event to occur. Neither the Master Servicer nor the
Special Servicer shall have any liability hereunder for any action taken by it
in accordance with the written instructions of the REMIC Administrator. The
REMIC Administrator may consult with counsel to make such written advice, and
the cost of same shall be borne by the party seeking to take the action not
expressly permitted by this Agreement, but in no event at the cost or expense of
the Trust Fund, the REMIC Administrator or the Trustee. Under no circumstances
may the REMIC Administrator vary the assets of the Grantor Trust so as to take
advantage of variations in the market so as to improve the rate of return of
Holders of the Class Z-I and Class Z-II Certificates.

     (f) If any tax is imposed on the Grantor Trust, such tax, together with all
incidental costs and expenses (including, without limitation, penalties and
reasonable attorneys' fees), shall be charged to and paid by: (i) the REMIC
Administrator, if such tax arises out of or results from a breach by the REMIC
Administrator of any of its obligations under this Section 10.02; (ii) the
Special Servicer, if such tax arises out of or results from a breach by the
Special Servicer of any of its obligations under Article III or this Section
10.02; (iii) the Master Servicer, if such tax arises out of or results from a
breach by the Master Servicer of any of its obligations under Article III or
this Section 10.02; (iv) the Trustee, if such tax arises out of or results from
a breach by the Trustee, of any of its obligations under Article IV, Article
VIII or this Section 10.02; or (v) the portion of the Trust Fund constituting
the Grantor Trust in all other instances.

Transferor) to be subject to a federal tax caused by a Transfer to a Person that
is not a Permitted Transferee, (vi) to relax or eliminate any requirement
hereunder imposed by the Securities Act or the rules thereunder if the

this Agreement shall be for any reason whatsoever held invalid, then such
covenants, agreements, provisions or terms shall be deemed severable from the
remaining covenants, agreements, provisions or terms of this Agreement and shall
in no way affect the validity or enforceability of the other provisions of this

     SECTION 11.07   Grant of a Security Interest.

     The Depositor intends that the conveyance of the Depositor's right, title

deemed to be a pledge of security for a loan, however, the Depositor intends
that the rights and obligations of the parties to such loan shall be established
pursuant to the terms of this Agreement. The Depositor also intends and agrees

have any effect, and if said Section 126 should at any time be repealed or cease
to apply to this Agreement or be construed by judicial decision to be
inapplicable, said Section 126 shall cease to have any further effect upon the
provisions of this Agreement. In case of a conflict between the provisions of
this Agreement and any mandatory provisions of Article 4-A of the New York Real
Property Law, such mandatory provisions of said Article 4-A shall prevail,
provided that if said Article 4-A shall not apply to this Agreement, should at
any time be repealed, or cease to apply to this Agreement or be construed by
judicial decision to be inapplicable, such mandatory provisions of such Article
4-A shall cease to have any further effect upon the provisions of this
Agreement.

respect to each Distribution Date, the Determination Date is the 4th Business
Day prior to the Distribution Date (each, a "Determination Date"). Distributions
will be made commencing on the first Distribution Date specified above, to the
Person in whose name this Certificate is registered at the close of business on
the last Business Day of the month immediately preceding the month of such
distribution (the "Record Date"), in an amount equal to the product of the
Percentage Interest evidenced by this Certificate and the amount required to be
distributed to the Holders of the Class A-1 Certificates on the applicable
Distribution Date pursuant to the Agreement. All distributions made under the
Agreement on the Class A-1 Certificates will be made by the Trustee, by wire
transfer of immediately available funds to the account of the Person entitled
thereto at a bank or other entity having appropriate facilities therefor, if
such Certificateholder shall have provided the Trustee with wiring instructions
no less than five Business Days prior to the related Record Date (which wiring
instructions may be in the form of a standing order applicable to all subsequent
distributions), or otherwise by check mailed to the address of such
Certificateholder as it appears in the Certificate Register. Notwithstanding the
foregoing, the final distribution on this Certificate (determined without regard
to any possible future reimbursement of any Realized Loss or Additional Trust
Fund Expense previously allocated to this Certificate) will be made in like
manner, but only upon presentation and surrender of this Certificate at the
offices of the Certificate Registrar or such other location specified in the
notice to the Holder hereof of such final distribution. Also notwithstanding the
foregoing, any distribution that may be made with respect to this Certificate in
reimbursement of any Realized Loss or Additional Trust Fund Expense previously
allocated to this Certificate, which reimbursement is to occur after the date on
which this Certificate is surrendered as contemplated by the preceding sentence,
will be made by check mailed to the address of the Holder that surrenders this
Certificate as such address last appears in the Certificate Register or to any
such other address of which the Trustee is subsequently notified in writing.

                  The Certificates are limited in right of distribution to
certain collections and recoveries respecting the Mortgage Loans, all as more
specifically set forth herein and in the Agreement. As provided in the
Agreement, withdrawals from the Certificate Account, the Distribution Account
and, if established, the REO Account may be made from time to time for purposes
other than, and, in certain cases, prior to, distributions to
Certificateholders, such purposes including the reimbursement of advances made,
or certain expenses incurred, with respect to the Mortgage Loans and the payment
of interest on such advances and expenses.

                  Interest accrued on this Certificate during an Interest
Accrual Period, plus any unpaid interest shortfall with respect to this
Certificate for any prior Distribution Date, if any, will be payable on the
related Distribution Date to the extent provided in the Agreement. The "Interest
Accrual Period" with respect to any Distribution Date and with respect to the
Class A-1 Certificates is the calendar month preceding the month in which such
Distribution Date occurs and is assumed to consist of 30 days.

                  Any distribution to the Holder of this Certificate in
reduction of the Certificate Principal Balance hereof is binding on such Holder
and all future Holders of this Certificate and

<PAGE>

any Certificate issued upon the transfer hereof or in exchange herefor or in
lieu hereof whether or not notation of such distribution is made upon this
Certificate.

                  The Class A-1 Certificates are issuable in fully registered
form only without coupons in minimum denominations specified in the Agreement.
As provided in the Agreement and subject to certain limitations therein set
forth, Class A-1 Certificates are exchangeable for new Class A-1 Certificates in
authorized denominations evidencing the same aggregate Percentage Interest, as
requested by the Holder surrendering the same.

                  As provided in the Agreement and subject to certain
limitations therein set forth, the transfer of this Certificate is registrable
in the Certificate Register upon surrender of this Certificate for registration
of transfer at the offices of the Certificate Registrar, duly endorsed by, or
accompanied by a written instrument of transfer in the form satisfactory to the
Certificate Registrar duly executed by, the Holder hereof or his attorney duly
authorized in writing, and thereupon one or more new Class A-1 Certificates in
authorized denominations evidencing the same aggregate Percentage Interest will
be issued to the designated transferee or transferees.

                  No service charge will be imposed for any registration of
transfer or exchange of Class A-1 Certificates, but the Certificate Registrar
may require payment of a sum sufficient to cover any tax or other governmental
charge that may be imposed in connection with any transfer or exchange of Class
A-1 Certificates.

                  Notwithstanding the foregoing, for so long as this Certificate
is registered in the name of Cede & Co. or in such other name as is requested by
an authorized representative of DTC, transfers of interests in this Certificate
shall be made through the book-entry facilities of DTC.

                  The Depositor, the Master Servicer, the Special Servicer, the
Trustee, and the Certificate Registrar and any agent of the Depositor, the
Master Servicer, the Special Servicer, the Trustee, or the Certificate Registrar
may treat the Person in whose name this Certificate is registered as the owner
hereof for all purposes whatsoever and none of the Depositor, the Master
Servicer, the Special Servicer, the Trustee, the Certificate Registrar or any
such agent shall be affected by notice to the contrary.

                  The Trust Fund and the obligations created by the Agreement
shall terminate upon distribution (or provision for distribution) to the
Certificateholders of all amounts held by or on behalf of the Trustee and
required to be distributed to them pursuant to the Agreement following the
earlier to occur of (i) the final payment (or any advance with respect thereto)
or other liquidation of the last Mortgage Loan or REO Property remaining in the
Trust Fund, and (ii) the purchase by the Master Servicer, the Special Servicer
or the Majority Subordinate Certificateholder at a price determined as provided
in the Agreement of all Mortgage Loans and each REO Property remaining in the
Trust Fund. The Agreement permits, but does not require, the Master Servicer,
the Special Servicer or the Majority Subordinate Certificateholder to purchase
from the Trust Fund all Mortgage Loans and each REO Property remaining therein.
The exercise of such right will effect early retirement of the Class A-1
Certificates; however, such right to purchase is subject to the aggregate Stated
Principal Balance of the Mortgage Pool

<PAGE>

at the time of purchase being less than 1% of the aggregate Stated Principal
Balance of the Mortgage Loans as of the Closing Date specified on the face
hereof.

                  The Agreement permits, with certain exceptions therein
provided, the amendment thereof and the modification of the rights and
obligations of the Depositor, the Master Servicer, the Special Servicer and the
Trustee and the rights of the Certificateholders under the Agreement at any time
by the Depositor, the Master Servicer, the Special Servicer and the Trustee with
the consent of the Holders of Certificates entitled to at least 51% of the
Voting Rights allocated to the affected Classes. Any such consent by the Holder
of this Certificate shall be conclusive and binding on such Holder and upon all
future Holders of this Certificate and of any Certificate issued upon the
transfer hereof or in exchange herefor or in lieu hereof whether or not notation
of such consent is made upon this Certificate. The Agreement also permits the
amendment thereof, in certain limited circumstances, including any amendment
necessary to maintain the status of the Trust Fund (or designated portions
thereof) as consisting of three separate REMICs and a grantor trust, without the
consent of the Holders of any of the Certificates.

                  Unless the certificate of authentication hereon has been
executed by the Certificate Registrar, by manual signature, this Certificate
shall not be entitled to any benefit under the Agreement or be valid for any
purpose.

                  The registered Holder hereof, by its acceptance hereof, agrees
that it will look solely to the Trust Fund (to the extent of its rights therein)
for distributions hereunder.

                  This Certificate shall be construed in accordance with the
internal laws of the State of New York applicable to agreements made and to be
performed in said State, and the obligations, rights and remedies of the Holder
hereof shall be determined in accordance with such laws.

                  IN WITNESS WHEREOF, the Certificate Registrar has caused this
Certificate to be duly executed.

                  This certifies that Cede & Co. is the registered owner of the
Percentage Interest evidenced by this Class A-2 Certificate (obtained by

requested by the Holder surrendering the same.

                  As provided in the Agreement and subject to certain

of transfer at the offices of the Certificate Registrar, duly endorsed by, or
accompanied by a written instrument of transfer in the form satisfactory to the
Certificate Registrar duly executed by, the Holder hereof or his attorney duly
authorized in writing, and thereupon one or more new Class A-2 Certificates in
authorized denominations evidencing the same aggregate Percentage Interest will
be issued to the designated transferee or transferees.

                  No service charge will be imposed for any registration of
transfer or exchange of Class A-2 Certificates, but the Certificate Registrar
may require payment of a sum sufficient to cover any tax or other governmental
charge that may be imposed in connection with any transfer or exchange of Class
A-2 Certificates.

                  Notwithstanding the foregoing, for so long as this Certificate
is registered in the name of Cede & Co. or in such other name as is requested by
an authorized representative of DTC, transfers of interests in this Certificate
shall be made through the book-entry facilities of DTC.

Servicer, the Special Servicer, the Trustee, the Certificate Registrar or any
such agent shall be affected by notice to the contrary.

shall terminate upon distribution (or provision for distribution) to the
Certificateholders of all amounts held by or on behalf of the Trustee and
required to be distributed to them pursuant to the Agreement following the
earlier to occur of (i) the final payment (or any advance with respect thereto)
or other liquidation of the last Mortgage Loan or REO Property remaining in the
Trust Fund, and (ii) the purchase by the Master Servicer, the Special Servicer
or the Majority Subordinate Certificateholder at a price determined as provided
in the Agreement of all Mortgage Loans and each REO Property remaining in the
Trust Fund. The Agreement permits, but does not require, the Master Servicer,
the Special Servicer or the Majority Subordinate Certificateholder to purchase
from the Trust Fund all Mortgage Loans and each REO Property remaining therein.
The exercise of such right will effect early retirement of the Class A-2
Certificates; however, such right to purchase is subject to the aggregate Stated
Principal Balance of the Mortgage Pool at the time of purchase being less than
1% of the aggregate Stated Principal Balance of the Mortgage Loans as of the
Closing Date specified on the face hereof.

<PAGE>

                  The Agreement permits, with certain exceptions therein
provided, the amendment thereof and the modification of the rights and
obligations of the Depositor, the Master Servicer, the Special Servicer and the
Trustee and the rights of the Certificateholders under the Agreement at any time
by the Depositor, the Master Servicer, the Special Servicer, and the Trustee
with the consent of the Holders of Certificates entitled to at least 51% of the
Voting Rights allocated to the affected Classes. Any such consent by the Holder
of this Certificate shall be conclusive and binding on such Holder and upon all
future Holders of this Certificate and of any Certificate issued upon the
transfer hereof or in exchange herefor or in lieu hereof whether or not notation
of such consent is made upon this Certificate. The Agreement also permits the
amendment thereof, in certain limited circumstances, including any amendment
necessary to maintain the status of the Trust Fund (or designated portions
thereof) as consisting of three separate REMICs and a grantor trust, without the
consent of the Holders of any of the Certificates.

                  Unless the certificate of authentication hereon has been
executed by the Certificate Registrar, by manual signature, this Certificate
shall not be entitled to any benefit under the Agreement or be valid for any
purpose.

                  The registered Holder hereof, by its acceptance hereof, agrees
that it will look solely to the Trust Fund (to the extent of its rights therein)
for distributions hereunder.

                  This Certificate shall be construed in accordance with the
internal laws of the State of New York applicable to agreements made and to be
performed in said State, and the obligations, rights and remedies of the Holder
hereof shall be determined in accordance with such laws.

                  This certifies that Cede & Co. is the registered owner of the
Percentage Interest evidenced by this Class A-3 Certificate (obtained by
dividing the principal amount of this Class A-3 Certificate (its "Certificate

Certificate is issued under and is subject to the terms, provisions and
conditions of the Agreement, to which

<PAGE>

Agreement the Holder of this Certificate by virtue of the acceptance hereof
assents and by which such Holder is bound.

                  Pursuant to the terms of the Agreement, distributions will be
made on the 12th day of any given month, or if the 12th day is not a Business
Day, on the next succeeding Business Day (each, a "Distribution Date"). With
respect to each Distribution Date, the Determination Date is the 4th Business

will be made commencing on the first Distribution Date specified above, to the
Person in whose name this Certificate is registered at the close of business on
the last Business Day of the month immediately preceding the month of such
distribution (the "Record Date"), in an amount equal to the product of the
Percentage Interest evidenced by this Certificate and the amount required to be
distributed to the Holders of the Class A-3 Certificates on the applicable
Distribution Date pursuant to the Agreement. All distributions made under the
Agreement on the Class A-3 Certificates will be made by the Trustee, by wire
transfer of immediately available funds to the account of the Person entitled
thereto at a bank or other entity having appropriate facilities therefor, if
such Certificateholder shall have provided the Trustee with wiring instructions

foregoing, the final distribution on this Certificate (determined without regard
to any possible future reimbursement of any Realized Loss or Additional Trust
Fund Expense previously allocated to this Certificate) will be made in like
manner, but only upon presentation and surrender of this Certificate at the
offices of the Certificate Registrar or such other location specified in the

which this Certificate is surrendered as contemplated by the preceding sentence,
will be made by check mailed to the address of the Holder that surrenders this
Certificate as such address last appears in the Certificate Register or to any
such other address of which the Trustee is subsequently notified in writing.

                  The Certificates are limited in right of distribution to
certain collections and recoveries respecting the Mortgage Loans, all as more
specifically set forth herein and in the Agreement. As provided in the
Agreement, withdrawals from the Certificate Account, the Distribution Account
and, if established, the REO Account may be made from time to time for purposes
other than, and, in certain cases, prior to, distributions to
Certificateholders, such purposes including the reimbursement of advances made,
or certain expenses incurred, with respect to the Mortgage Loans and the payment

Accrual Period, plus any unpaid interest shortfall with respect to this
Certificate for any prior Distribution Date, if any, will be payable on the
related Distribution Date to the extent provided in the Agreement. The "Interest
Accrual Period" with respect to any Distribution Date and with respect to the
Class A-3

<PAGE>

Certificates is the calendar month preceding the month in which such
Distribution Date occurs and is assumed to consist of 30 days.

                  Any distribution to the Holder of this Certificate in
reduction of the Certificate Principal Balance hereof is binding on such Holder
and all future Holders of this Certificate and any Certificate issued upon the
transfer hereof or in exchange herefor or in lieu hereof whether or not notation
of such distribution is made upon this Certificate.

                  The Class A-3 Certificates are issuable in fully registered
form only without coupons in minimum denominations specified in the Agreement.
As provided in the Agreement and subject to certain limitations therein set
forth, Class A-3 Certificates are exchangeable for new Class A-3 Certificates in
authorized denominations evidencing the same aggregate Percentage Interest, as
requested by the Holder surrendering the same.

                  As provided in the Agreement and subject to certain
limitations therein set forth, the transfer of this Certificate is registrable
in the Certificate Register upon surrender of this Certificate for registration
of transfer at the offices of the Certificate Registrar, duly endorsed by, or
accompanied by a written instrument of transfer in the form satisfactory to the
Certificate Registrar duly executed by, the Holder hereof or his attorney duly
authorized in writing, and thereupon one or more new Class A-3 Certificates in
authorized denominations evidencing the same aggregate Percentage Interest will
be issued to the designated transferee or transferees.

                  No service charge will be imposed for any registration of
transfer or exchange of Class A-3 Certificates, but the Certificate Registrar
may require payment of a sum sufficient to cover any tax or other governmental
charge that may be imposed in connection with any transfer or exchange of Class
A-3 Certificates.

                  Notwithstanding the foregoing, for so long as this Certificate
is registered in the name of Cede & Co. or in such other name as is requested by
an authorized representative of DTC, transfers of interests in this Certificate
shall be made through the book-entry facilities of DTC.

                  The Depositor, the Master Servicer, the Special Servicer, the
Trustee, and the Certificate Registrar and any agent of the Depositor, the
Master Servicer, the Special Servicer, the Trustee, or the Certificate Registrar
may treat the Person in whose name this Certificate is registered as the owner
hereof for all purposes whatsoever and none of the Depositor, the Master
Servicer, the Special Servicer, the Trustee, the Certificate Registrar or any
such agent shall be affected by notice to the contrary.

                  The Trust Fund and the obligations created by the Agreement
shall terminate upon distribution (or provision for distribution) to the
Certificateholders of all amounts held by or on behalf of the Trustee and
required to be distributed to them pursuant to the Agreement following the
earlier to occur of (i) the final payment (or any advance with respect thereto)
or other liquidation of the last Mortgage Loan or REO Property remaining in the
Trust Fund, and (ii) the purchase by the Master Servicer, the Special Servicer
or the Majority Subordinate Certificateholder at a price determined as provided
in the Agreement of all Mortgage Loans and

<PAGE>

each REO Property remaining in the Trust Fund. The Agreement permits, but does
not require, the Master Servicer, the Special Servicer or the Majority
Subordinate Certificateholder to purchase from the Trust Fund all Mortgage Loans
and each REO Property remaining therein. The exercise of such right will effect
early retirement of the Class A-3 Certificates; however, such right to purchase
is subject to the aggregate Stated Principal Balance of the Mortgage Pool at the
time of purchase being less than 1% of the aggregate Stated Principal Balance of
the Mortgage Loans as of the Closing Date specified on the face hereof.

                  The Agreement permits, with certain exceptions therein
provided, the amendment thereof and the modification of the rights and
obligations of the Depositor, the Master Servicer, the Special Servicer and the
Trustee and the rights of the Certificateholders under the Agreement at any time
by the Depositor, the Master Servicer, the Special Servicer and the Trustee with
the consent of the Holders of Certificates entitled to at least 51% of the
Voting Rights allocated to the affected Classes. Any such consent by the Holder
of this Certificate shall be conclusive and binding on such Holder and upon all
future Holders of this Certificate and of any Certificate issued upon the
transfer hereof or in exchange herefor or in lieu hereof whether or not notation
of such consent is made upon this Certificate. The Agreement also permits the
amendment thereof, in certain limited circumstances, including any amendment
necessary to maintain the status of the Trust Fund (or designated portions
thereof) as consisting of three separate REMICs and a grantor trust, without the
consent of the Holders of any of the Certificates.

                  Unless the certificate of authentication hereon has been
executed by the Certificate Registrar, by manual signature, this Certificate
shall not be entitled to any benefit under the Agreement or be valid for any
purpose.

                  The registered Holder hereof, by its acceptance hereof, agrees
that it will look solely to the Trust Fund (to the extent of its rights therein)
for distributions hereunder.

                  This Certificate shall be construed in accordance with the
internal laws of the State of New York applicable to agreements made and to be
performed in said State, and the obligations, rights and remedies of the Holder
hereof shall be determined in accordance with such laws.

                  IN WITNESS WHEREOF, the Certificate Registrar has caused this
Certificate to be duly executed.

certain collections and recoveries respecting the Mortgage Loans, all as more
specifically set forth herein and in the Agreement. As provided in the
Agreement, withdrawals from the Certificate Account, the Distribution Account
and, if established, the REO Account may be made from time to time for purposes
other than, and, in certain cases, prior to, distributions to
Certificateholders, such purposes including the reimbursement of advances made,
or certain expenses incurred, with respect to the Mortgage Loans and the payment

                  Interest accrued on this Certificate during an Interest
Accrual Period, plus any unpaid interest shortfall with respect to this
Certificate for any prior Distribution Date, if any, will be payable on the
related Distribution Date to the extent provided in the Agreement. The "Interest
Accrual Period" with respect to any Distribution Date and with respect to the
Class A-4

<PAGE>

Certificates is the calendar month preceding the month in which such
Distribution Date occurs and is assumed to consist of 30 days.

                  Any distribution to the Holder of this Certificate in
reduction of the Certificate Principal Balance hereof is binding on such Holder
and all future Holders of this Certificate and any Certificate issued upon the
transfer hereof or in exchange herefor or in lieu hereof whether or not notation
of such distribution is made upon this Certificate.

                  The Class A-4 Certificates are issuable in fully registered
form only without coupons in minimum denominations specified in the Agreement.
As provided in the Agreement and subject to certain limitations therein set
forth, Class A-4 Certificates are exchangeable for new Class A-4 Certificates in
authorized denominations evidencing the same aggregate Percentage Interest, as
requested by the Holder surrendering the same.

                  As provided in the Agreement and subject to certain
limitations therein set forth, the transfer of this Certificate is registrable
in the Certificate Register upon surrender of this Certificate for registration
of transfer at the offices of the Certificate Registrar, duly endorsed by, or
accompanied by a written instrument of transfer in the form satisfactory to the
Certificate Registrar duly executed by, the Holder hereof or his attorney duly
authorized in writing, and thereupon one or more new Class A-4 Certificates in
authorized denominations evidencing the same aggregate Percentage Interest will
be issued to the designated transferee or transferees.

                  No service charge will be imposed for any registration of
transfer or exchange of Class A-4 Certificates, but the Certificate Registrar
may require payment of a sum sufficient to cover any tax or other governmental
charge that may be imposed in connection with any transfer or exchange of Class
A-4 Certificates.

                  Notwithstanding the foregoing, for so long as this Certificate
is registered in the name of Cede & Co. or in such other name as is requested by
an authorized representative of DTC, transfers of interests in this Certificate
shall be made through the book-entry facilities of DTC.

                  The Depositor, the Master Servicer, the Special Servicer, the
Trustee, and the Certificate Registrar and any agent of the Depositor, the
Master Servicer, the Special Servicer, the Trustee, or the Certificate Registrar
may treat the Person in whose name this Certificate is registered as the owner
hereof for all purposes whatsoever and none of the Depositor, the Master
Servicer, the Special Servicer, the Trustee, the Certificate Registrar or any
such agent shall be affected by notice to the contrary.

                  The Trust Fund and the obligations created by the Agreement
shall terminate upon distribution (or provision for distribution) to the
Certificateholders of all amounts held by or on behalf of the Trustee and
required to be distributed to them pursuant to the Agreement following the
earlier to occur of (i) the final payment (or any advance with respect thereto)
or other liquidation of the last Mortgage Loan or REO Property remaining in the
Trust Fund, and (ii) the purchase by the Master Servicer, the Special Servicer
or the Majority Subordinate Certificateholder at a price determined as provided
in the Agreement of all Mortgage Loans and

<PAGE>

each REO Property remaining in the Trust Fund. The Agreement permits, but does
not require, the Master Servicer, the Special Servicer or the Majority
Subordinate Certificateholder to purchase from the Trust Fund all Mortgage Loans
and each REO Property remaining therein. The exercise of such right will effect
early retirement of the Class A-4 Certificates; however, such right to purchase
is subject to the aggregate Stated Principal Balance of the Mortgage Pool at the
time of purchase being less than 1% of the aggregate Stated Principal Balance of
the Mortgage Loans as of the Closing Date specified on the face hereof.

                  The Agreement permits, with certain exceptions therein
provided, the amendment thereof and the modification of the rights and
obligations of the Depositor, the Master Servicer, the Special Servicer and the
Trustee and the rights of the Certificateholders under the Agreement at any time
by the Depositor, the Master Servicer, the Special Servicer and the Trustee with
the consent of the Holders of Certificates entitled to at least 51% of the
Voting Rights allocated to the affected Classes. Any such consent by the Holder
of this Certificate shall be conclusive and binding on such Holder and upon all
future Holders of this Certificate and of any Certificate issued upon the
transfer hereof or in exchange herefor or in lieu hereof whether or not notation
of such consent is made upon this Certificate. The Agreement also permits the
amendment thereof, in certain limited circumstances, including any amendment
necessary to maintain the status of the Trust Fund (or designated portions
thereof) as consisting of three separate REMICs and a grantor trust, without the
consent of the Holders of any of the Certificates.

                  Unless the certificate of authentication hereon has been
executed by the Certificate Registrar, by manual signature, this Certificate
shall not be entitled to any benefit under the Agreement or be valid for any
purpose.

                  The registered Holder hereof, by its acceptance hereof, agrees
that it will look solely to the Trust Fund (to the extent of its rights therein)
for distributions hereunder.

                  This Certificate shall be construed in accordance with the
internal laws of the State of New York applicable to agreements made and to be
performed in said State, and the obligations, rights and remedies of the Holder
hereof shall be determined in accordance with such laws.

TRUST FUND AS SET FORTH IN THE POOLING AND SERVICING AGREEMENT REFERRED TO

                  This certifies that Cede & Co. is the registered owner of the
Percentage Interest evidenced by this Class A-1A Certificate (obtained by
dividing the principal amount of this Class A-1A Certificate (its "Certificate

used herein have the respective meanings assigned in the Agreement. This
Certificate is issued under and is subject to the terms, provisions and
conditions of the Agreement, to which Agreement the Holder of this Certificate
by virtue of the acceptance hereof assents and by which such Holder is bound.

                  Pursuant to the terms of the Agreement, distributions will be
made on the 12th day of any given month, or if the 12th day is not a Business
Day, on the next succeeding Business Day (each, a "Distribution Date"). With
respect to each Distribution Date, the Determination Date is the 4th Business
Day prior to the Distribution Date (each, a "Determination Date"). Distributions
will be made commencing on the first Distribution Date specified above, to the
Person in whose name this Certificate is registered at the close of business on
the last Business Day of the month immediately preceding the month of such

notice to the Holder hereof of such final distribution. Also notwithstanding the
foregoing, any distribution that may be made with respect to this Certificate in
reimbursement of any Realized Loss or Additional Trust Fund Expense previously
allocated to this Certificate, which reimbursement is to occur after the date on
which this Certificate is surrendered as contemplated by the preceding sentence,
will be made by check mailed to the address of the Holder that surrenders this
Certificate as such address last appears in the Certificate Register or to any
such other address of which the Trustee is subsequently notified in writing.

                  The Certificates are limited in right of distribution to
certain collections and recoveries respecting the Mortgage Loans, all as more
specifically set forth herein and in the Agreement. As provided in the
Agreement, withdrawals from the Certificate Account, the Distribution Account
and, if established, the REO Account may be made from time to time for purposes
other than, and, in certain cases, prior to, distributions to
Certificateholders, such

<PAGE>

purposes including the reimbursement of advances made, or certain expenses
incurred, with respect to the Mortgage Loans and the payment of interest on such
advances and expenses.

                  Interest accrued on this Certificate during an Interest
Accrual Period, plus any unpaid interest shortfall with respect to this
Certificate for any prior Distribution Date, if any, will be payable on the
related Distribution Date to the extent provided in the Agreement. The "Interest
Accrual Period" with respect to any Distribution Date and with respect to the
Class A-1A Certificates is the calendar month preceding the month in which such
Distribution Date occurs and is assumed to consist of 30 days.

                  Any distribution to the Holder of this Certificate in
reduction of the Certificate Principal Balance hereof is binding on such Holder
and all future Holders of this Certificate and any Certificate issued upon the
transfer hereof or in exchange herefor or in lieu hereof whether or not notation
of such distribution is made upon this Certificate.

                  The Class A-1A Certificates are issuable in fully registered
form only without coupons in minimum denominations specified in the Agreement.
As provided in the Agreement and subject to certain limitations therein set
forth, Class A-1A Certificates are exchangeable for new Class A-1A Certificates
in authorized denominations evidencing the same aggregate Percentage Interest,
as requested by the Holder surrendering the same.

                  As provided in the Agreement and subject to certain
limitations therein set forth, the transfer of this Certificate is registrable
in the Certificate Register upon surrender of this Certificate for registration
of transfer at the offices of the Certificate Registrar, duly endorsed by, or
accompanied by a written instrument of transfer in the form satisfactory to the
Certificate Registrar duly executed by, the Holder hereof or his attorney duly
authorized in writing, and thereupon one or more new Class A-1A Certificates in
authorized denominations evidencing the same aggregate Percentage Interest will
be issued to the designated transferee or transferees.

                  With respect to any offer, sale, pledge or other transfer of
any Class A-1A Certificate, no such transfer of a Class A-1A Certificate shall
be made unless that transfer is made pursuant to an effective registration
statement under the Securities Act, and effective registration or qualification
under applicable state securities laws, or is made in a transaction which does
not require such registration or qualification. If such a transfer is to be made
without registration under the Securities Act (other than in connection with the
initial issuance thereof or the initial transfer thereof by the Depositor, the
Underwriters or their respective affiliates), then the Certificate Registrar
shall refuse to register such transfer unless it receives either: (i) a
certificate from the Certificateholder desiring to effect such transfer
substantially in the form attached as Exhibit E-1 to the Agreement, and a
certificate from such Certificateholder's prospective transferee substantially
in the form attached as either Exhibit E-2 (which relates to sales to QIBs in
reliance on Rule 144A) or Exhibit E-3 (which relates to sales to Institutional
Accredited Investors) to the Agreement; or (ii) an Opinion of Counsel
satisfactory to the Certificate Registrar to the effect that such transfer may
be made without registration under the Securities Act (which Opinion of Counsel
shall not be an expense of the Trust Fund or of the Depositor, the Master
Servicer, the Special Servicer, the Trustee or the Certificate Registrar in
their respective capacities as such), together with the written certification(s)
as to the facts

<PAGE>

surrounding such transfer from the Certificateholder desiring to effect such
transfer and/or such Certificateholder's prospective transferee on which such
Opinion of Counsel is based. None of the Depositor, the Trustee or the
Certificate Registrar is obligated to register or qualify the Class A-1A
Certificates under the Securities Act or any other securities law or to take any
action not otherwise required under the Agreement to permit the transfer of any
Class A-1A Certificate without registration or qualification. Any Class A-1A
Certificateholder desiring to effect such a transfer shall, and by the
acceptance of its Class A-1A Certificate agrees to, indemnify the Trustee, the
Certificate Registrar and the Depositor against any liability that may result if
the transfer is not so exempt or is not made in accordance with such federal and
state laws.

                  With respect to any offer, sale, pledge or other transfer of
any Class A-1A Certificate that constitutes a Class of Book-Entry Certificates,
if such a transfer is to be made without registration under the Securities Act,
such transfer will not be made unless the prospective transferee delivers to the
transferor (i) a certificate substantially in the form of Exhibit E-2 hereto and
addressed to the transferor, upon or prior to such transfer, or (ii) an opinion
of counsel to the effect that such transferee is a QIB and that such transfer
may be made without registration under the Securities Act, together with the
written certification(s) as to the facts surrounding such transfer, from the
prospective transferor desiring to effect such transfer and/or the prospective
transferee, on which such opinion of counsel is based. In any event, (a) each
prospective transferor of such Class A-1A Certificate will be deemed to have
represented to the Trustee, the Depositor and the transferee of such Certificate
the information set forth on Exhibit E-1 upon or prior to such transfer and (b)
each prospective transferee of such Certificate will be deemed to have
represented to the Trustee, the Depositor and the transferor of such Certificate
the information set forth on Exhibit E-2 hereto.

                  An Institutional Accredited Investor (other than a QIB) may
not hold an interest in a Class A-1A Certificate in book-entry form and must
hold such interest in a Class A-1A Certificate in definitive form. Any transfer
of such Certificates will require, among other things described herein and in
the Agreement, delivery of the certificates and/or opinions required in
connection with the transfer of a Class A-1A Certificate held in a physical
certificated form, as set forth above.

                  No service charge will be imposed for any registration of
transfer or exchange of Class A-1A Certificates, but the Certificate Registrar
may require payment of a sum sufficient to cover any tax or other governmental
charge that may be imposed in connection with any transfer or exchange of Class
A-1A Certificates.

                  Notwithstanding the foregoing, for so long as this Certificate
is registered in the name of Cede & Co. or in such other name as is requested by
an authorized representative of DTC, transfers of interests in this Certificate
shall be made through the book-entry facilities of DTC.

                  The Depositor, the Master Servicer, the Special Servicer, the
Trustee, and the Certificate Registrar and any agent of the Depositor, the
Master Servicer, the Special Servicer, the Trustee, or the Certificate Registrar
may treat the Person in whose name this Certificate is

<PAGE>

registered as the owner hereof for all purposes whatsoever and none of the
Depositor, the Master Servicer, the Special Servicer, the Trustee, the
Certificate Registrar or any such agent shall be affected by notice to the
contrary.

                  The Trust Fund and the obligations created by the Agreement
shall terminate upon distribution (or provision for distribution) to the
Certificateholders of all amounts held by or on behalf of the Trustee and
required to be distributed to them pursuant to the Agreement following the
earlier to occur of (i) the final payment (or any advance with respect thereto)
or other liquidation of the last Mortgage Loan or REO Property remaining in the
Trust Fund, and (ii) the purchase by the Master Servicer, the Special Servicer
or the Majority Subordinate Certificateholder at a price determined as provided
in the Agreement of all Mortgage Loans and each REO Property remaining in the
Trust Fund. The Agreement permits, but does not require, the Master Servicer,
the Special Servicer or the Majority Subordinate Certificateholder to purchase
from the Trust Fund all Mortgage Loans and each REO Property remaining therein.
The exercise of such right will effect early retirement of the Class A-1A
Certificates; however, such right to purchase is subject to the aggregate Stated
Principal Balance of the Mortgage Pool at the time of purchase being less than
1% of the aggregate Stated Principal Balance of the Mortgage Loans as of the
Closing Date specified on the face hereof.

                  The Agreement permits, with certain exceptions therein
provided, the amendment thereof and the modification of the rights and
obligations of the Depositor, the Master Servicer, the Special Servicer and the
Trustee and the rights of the Certificateholders under the Agreement at any time
by the Depositor, the Master Servicer, the Special Servicer, and the Trustee
with the consent of the Holders of Certificates entitled to at least 51% of the
Voting Rights allocated to the affected Classes. Any such consent by the Holder
of this Certificate shall be conclusive and binding on such Holder and upon all
future Holders of this Certificate and of any Certificate issued upon the
transfer hereof or in exchange herefor or in lieu hereof whether or not notation
of such consent is made upon this Certificate. The Agreement also permits the
amendment thereof, in certain limited circumstances, including any amendment
necessary to maintain the status of the Trust Fund (or designated portions
thereof) as consisting of three separate REMICs and a grantor trust, without the
consent of the Holders of any of the Certificates.

                  Unless the certificate of authentication hereon has been
executed by the Certificate Registrar, by manual signature, this Certificate
shall not be entitled to any benefit under the Agreement or be valid for any
purpose.

                  The registered Holder hereof, by its acceptance hereof, agrees
that it will look solely to the Trust Fund (to the extent of its rights therein)
for distributions hereunder.

                  This Certificate shall be construed in accordance with the
internal laws of the State of New York applicable to agreements made and to be
performed in said State, and the obligations, rights and remedies of the Holder
hereof shall be determined in accordance with such laws.

THIS CERTIFICATE DOES NOT HAVE A CERTIFICATE PRINCIPAL BALANCE AND WILL NOT

THE MASTER SERVICER, THE TRUSTEE, THE CERTIFICATE REGISTRAR OR ANY AGENT THEREOF
FOR REGISTRATION OF TRANSFER, EXCHANGE, OR PAYMENT, AND ANY CERTIFICATE ISSUED
IS REGISTERED IN THE NAME OF CEDE & CO. OR IN SUCH OTHER NAME AS IS REQUESTED BY
AN AUTHORIZED REPRESENTATIVE OF DTC (AND ANY PAYMENT IS MADE TO CEDE & CO. OR TO
SUCH OTHER ENTITY AS IS REQUESTED BY AN AUTHORIZED REPRESENTATIVE OF DTC),

<PAGE>

ANY TRANSFER, PLEDGE OR OTHER USE HEREOF FOR VALUE OR OTHERWISE BY OR TO ANY
PERSON IS WRONGFUL INASMUCH AS THE REGISTERED OWNER HEREOF, CEDE & CO., HAS AN
INTEREST HEREIN.

THIS CERTIFICATE DOES NOT REPRESENT AN OBLIGATION OF OR INTEREST IN MERRILL

N.V., KEYCORP REAL ESTATE CAPITAL MARKETS, INC. OR ANY OF THEIR RESPECTIVE
AFFILIATES. NEITHER THIS CERTIFICATE NOR THE UNDERLYING MORTGAGE LOANS ARE
GUARANTEED BY ANY AGENCY OR INSTRUMENTALITY OF THE UNITED STATES OR ANY OTHER
PERSON.

THIS CERTIFICATE HAS NOT BEEN REGISTERED OR QUALIFIED UNDER THE SECURITIES ACT
OF 1933 (THE "SECURITIES ACT") OR THE SECURITIES LAWS OF ANY STATE. ANY RESALE,
TRANSFER OR OTHER DISPOSITION OF THIS CERTIFICATE WITHOUT SUCH REGISTRATION OR
QUALIFICATION MAY BE MADE ONLY IN A TRANSACTION WHICH DOES NOT REQUIRE SUCH
REGISTRATION OR QUALIFICATION AND IN ACCORDANCE WITH THE PROVISIONS OF SECTION
5.02 OF THE POOLING AND SERVICING AGREEMENT REFERRED TO HEREIN.

SOLELY FOR U.S. FEDERAL INCOME TAX PURPOSES, THIS CERTIFICATE IS A "REGULAR
INTEREST" IN A "REAL ESTATE MORTGAGE INVESTMENT CONDUIT" (A "REMIC") AS THOSE
TERMS ARE DEFINED, RESPECTIVELY, IN SECTIONS 860G AND 860D OF THE INTERNAL
REVENUE CODE OF 1986 (THE "CODE").

BECAUSE THE COMPONENTS COMPRISING THE NOTIONAL AMOUNT OF THE CLASS XC
CERTIFICATES WILL BE REDUCED BY ANY DISTRIBUTIONS IN REDUCTION OF THE
CERTIFICATE PRINCIPAL BALANCE OF THE CERTIFICATES RELATING TO SUCH COMPONENTS
AND BY CERTAIN LOSSES AND EXPENSES EXPERIENCED BY THE TRUST FUND WHICH ARE
ALLOCATED TO SUCH CERTIFICATES AS SET FORTH IN THE AGREEMENT, THE OUTSTANDING
NOTIONAL AMOUNT HEREOF AT ANY TIME MAY BE LESS THAN THE AMOUNT SHOWN ABOVE.

                  This certifies that Cede & Co. is the registered owner of the
Percentage Interest evidenced by this Class XC Certificate in that certain
beneficial ownership interest evidenced by all the Class XC Certificates in the
Trust Fund created pursuant to a Pooling and Servicing Agreement, dated as
specified above (the "Agreement"), among Merrill Lynch Mortgage Investors, Inc.
(herein called the "Depositor", which term includes any successor entity under
the Agreement), KeyCorp Real Estate Capital Markets, Inc. (herein called the
"Master Servicer", which term includes any successor entity under the
Agreement), ARCap Servicing, Inc. (herein called the "Special Servicer", which
term includes any successor entity under the Agreement), and LaSalle Bank
National Association (herein called the "Trustee", which term includes any
successor entity under the Agreement), and ABN AMRO Bank N.V. (herein called the
"Fiscal

<PAGE>

Agent", which term includes any successor entity under the Agreement), a summary
of certain of the pertinent provisions of which is set forth hereafter. To the
extent not defined herein, the capitalized terms used herein have the respective
meanings assigned in the Agreement. This Certificate is issued under and is
subject to the terms, provisions and conditions of the Agreement, to which
Agreement the Holder of this Certificate by virtue of the acceptance hereof
assents and by which such Holder is bound.

                  Pursuant to the terms of the Agreement, distributions will be
made on the 12th day of any given month, or if the 12th day is not a Business
Day, on the next succeeding Business Day (each, a "Distribution Date"). With
respect to each Distribution Date, the Determination Date is the 4th Business
Day prior to the Distribution Date (each, a "Determination Date"). Distributions
will be made commencing on the first Distribution Date specified above, to the
Person in whose name this Certificate is registered at the close of business on
the last Business Day of the month immediately preceding the month of such
distribution (the "Record Date"), in an amount equal to the product of the
Percentage Interest evidenced by this Certificate and the amount required to be
distributed to the Holders of the Class XC Certificates on the applicable
Distribution Date pursuant to the Agreement. The Pass-Through Rate applicable to
each Component of the Class XC Certificates for each Distribution Date is as
provided in the Agreement. All distributions made under the Agreement on the
Class XC Certificates will be made by the Trustee, by wire transfer of
immediately available funds to the account of the Person entitled thereto at a
bank or other entity having appropriate facilities therefor, if such
Certificateholder shall have provided the Trustee with wiring instructions no
less than five Business Days prior to the related Record Date (which wiring
instructions may be in the form of a standing order applicable to all subsequent
distributions), or otherwise by check mailed to the address of such
Certificateholder as it appears in the Certificate Register. Notwithstanding the
foregoing, the final distribution on this Certificate will be made in like
manner, but only upon presentation and surrender of this Certificate at the
offices of the Certificate Registrar or such other location specified in the
notice to the Holder hereof of such final distribution.

                  The Certificates are limited in right of distribution to
certain collections and recoveries respecting the Mortgage Loans, all as more
specifically set forth herein and in the Agreement. As provided in the
Agreement, withdrawals from the Certificate Account, the Distribution Account
and, if established, the REO Account may be made from time to time for purposes
other than, and, in certain cases, prior to, distributions to
Certificateholders, such purposes including the reimbursement of advances made,
or certain expenses incurred, with respect to the Mortgage Loans and the payment
of interest on such advances and expenses.

                  Interest accrued on this Certificate during an Interest
Accrual Period, plus any unpaid interest shortfall with respect to this
Certificate for any prior Distribution Date, if any, will be payable on the
related Distribution Date to the extent provided in the Agreement. The "Interest
Accrual Period" with respect to any Distribution Date and with respect to the
Class XC Certificates is the calendar month preceding the month in which such
Distribution Date occurs and is assumed to consist of 30 days.

                  The Class XC Certificates are issuable in fully registered
form only without coupons in minimum denominations specified in the Agreement.
As provided in the Agreement

<PAGE>

and subject to certain limitations therein set forth, Class XC Certificates are
exchangeable for new Class XC Certificates in authorized denominations
evidencing the same aggregate Percentage Interest, as requested by the Holder
surrendering the same.

                  As provided in the Agreement and subject to certain
limitations therein set forth, the transfer of this Certificate is registrable
in the Certificate Register upon surrender of this Certificate for registration
of transfer at the offices of the Certificate Registrar, duly endorsed by, or
accompanied by a written instrument of transfer in the form satisfactory to the
Certificate Registrar duly executed by, the Holder hereof or his attorney duly
authorized in writing, and thereupon one or more new Class XC Certificates in
authorized denominations evidencing the same aggregate Percentage Interest will
be issued to the designated transferee or transferees.

                  With respect to any offer, sale, pledge or other transfer of
any Class XC Certificate, no such transfer of a Class XC Certificate shall be
made unless that transfer is made pursuant to an effective registration
statement under the Securities Act, and effective registration or qualification
under applicable state securities laws, or is made in a transaction which does
not require such registration or qualification. If such a transfer is to be made
without registration under the Securities Act (other than in connection with the
initial issuance thereof or the initial transfer thereof by the Depositor, the
Underwriters or their respective affiliates), then the Certificate Registrar
shall refuse to register such transfer unless it receives either: (i) a
certificate from the Certificateholder desiring to effect such transfer
substantially in the form attached as Exhibit E-1 to the Agreement, and a
certificate from such Certificateholder's prospective transferee substantially
in the form attached as either Exhibit E-2 (which relates to sales to QIBs in
reliance on Rule 144A) or Exhibit E-3 (which relates to sales to Institutional
Accredited Investors) to the Agreement; or (ii) an Opinion of Counsel
satisfactory to the Certificate Registrar to the effect that such transfer may
be made without registration under the Securities Act (which Opinion of Counsel
shall not be an expense of the Trust Fund or of the Depositor, the Master
Servicer, the Special Servicer, the Trustee or the Certificate Registrar in
their respective capacities as such), together with the written certification(s)
as to the facts surrounding such transfer from the Certificateholder desiring to
effect such transfer and/or such Certificateholder's prospective transferee on
which such Opinion of Counsel is based. None of the Depositor, the Trustee or
the Certificate Registrar is obligated to register or qualify the Class XC
Certificates under the Securities Act or any other securities law or to take any
action not otherwise required under the Agreement to permit the transfer of any
Class XC Certificate without registration or qualification. Any Class XC
Certificateholder desiring to effect such a transfer shall, and by the
acceptance of its Class XC Certificate agrees to, indemnify the Trustee, the
Certificate Registrar and the Depositor against any liability that may result if
the transfer is not so exempt or is not made in accordance with such federal and
state laws.

                  With respect to any offer, sale, pledge or other transfer of
any Class XC Certificate that constitutes a Class of Book-Entry Certificates, if
such a transfer is to be made without registration under the Securities Act,
such transfer will not be made unless the prospective transferee delivers to the
transferor (i) a certificate substantially in the form of Exhibit E-2 hereto and
addressed to the transferor, upon or prior to such transfer, or (ii) an opinion
of counsel to the effect that such transferee is a QIB and that such transfer
may be made

<PAGE>

without registration under the Securities Act, together with the written
certification(s) as to the facts surrounding such transfer, from the prospective
transferor desiring to effect such transfer and/or the prospective transferee,
on which such opinion of counsel is based. In any event, (a) each prospective
transferor of such Class XC Certificate will be deemed to have represented to
the Trustee, the Depositor and the transferee of such Certificate the
information set forth on Exhibit E-1 upon or prior to such transfer and (b) each
prospective transferee of such Certificate will be deemed to have represented to
the Trustee, the Depositor and the transferor of such Certificate the
information set forth on Exhibit E-2 hereto.

                  An Institutional Accredited Investor (other than a QIB) may
not hold an interest in a Class XC Certificate in book-entry form and must hold
such interest in a Class XC Certificate in definitive form. Any transfer of such
Certificates will require, among other things described herein and in the
Agreement, delivery of the certificates and/or opinions required in connection
with the transfer of a Class XC Certificate held in a physical certificated
form, as set forth above.

                  No service charge will be imposed for any registration of
transfer or exchange of Class XC Certificates, but the Certificate Registrar may
require payment of a sum sufficient to cover any tax or other governmental
charge that may be imposed in connection with any transfer or exchange of Class
XC Certificates.

                  Notwithstanding the foregoing, for so long as this Certificate
is registered in the name of Cede & Co. or in such other name as is requested by
an authorized representative of DTC, transfers of interests in this Certificate
shall be made through the book-entry facilities of DTC.

                  The Depositor, the Master Servicer, the Special Servicer, the
Trustee, and the Certificate Registrar and any agent of the Depositor, the
Master Servicer, the Special Servicer, the Trustee, or the Certificate Registrar
may treat the Person in whose name this Certificate is registered as the owner
hereof for all purposes whatsoever and none of the Depositor, the Master
Servicer, the Special Servicer, the Trustee, the Certificate Registrar or any
such agent shall be affected by notice to the contrary.

                  The Trust Fund and the obligations created by the Agreement
shall terminate upon distribution (or provision for distribution) to the
Certificateholders of all amounts held by or on behalf of the Trustee and
required to be distributed to them pursuant to the Agreement following the
earlier to occur of (i) the final payment (or any advance with respect thereto)
or other liquidation of the last Mortgage Loan or REO Property remaining in the
Trust Fund, and (ii) the purchase by the Master Servicer, the Special Servicer
or the Majority Subordinate Certificateholder at a price determined as provided
in the Agreement of all Mortgage Loans and each REO Property remaining in the
Trust Fund. The Agreement permits, but does not require, the Master Servicer,
the Special Servicer or the Majority Subordinate Certificateholder to purchase
from the Trust Fund all Mortgage Loans and each REO Property remaining therein.
The exercise of such right will effect early retirement of the Class XC
Certificates; however, such right to purchase is subject to the aggregate Stated
Principal Balance of the Mortgage Pool

<PAGE>

at the time of purchase being less than 1% of the aggregate Stated Principal
Balance of the Mortgage Loans as of the Closing Date specified on the face
hereof.

                  The Agreement permits, with certain exceptions therein
provided, the amendment thereof and the modification of the rights and
obligations of the Depositor, the Master Servicer, the Special Servicer and the
Trustee and the rights of the Certificateholders under the Agreement at any time
by the Depositor, the Master Servicer, the Special Servicer and the Trustee with
the consent of the Holders of Certificates entitled to at least 51% of the
Voting Rights allocated to the affected Classes. Any such consent by the Holder
of this Certificate shall be conclusive and binding on such Holder and upon all
future Holders of this Certificate and of any Certificate issued upon the
transfer hereof or in exchange herefor or in lieu hereof whether or not notation
of such consent is made upon this Certificate. The Agreement also permits the
amendment thereof, in certain limited circumstances, including any amendment
necessary to maintain the status of the Trust Fund (or designated portions
thereof) as consisting of three separate REMICs and a grantor trust, without the
consent of the Holders of any of the Certificates.

                  Unless the certificate of authentication hereon has been
executed by the Certificate Registrar, by manual signature, this Certificate
shall not be entitled to any benefit under the Agreement or be valid for any
purpose.

                  The registered Holder hereof, by its acceptance hereof, agrees
that it will look solely to the Trust Fund (to the extent of its rights therein)
for distributions hereunder.

                  This Certificate shall be construed in accordance with the
internal laws of the State of New York applicable to agreements made and to be
performed in said State, and the obligations, rights and remedies of the Holder
hereof shall be determined in accordance with such laws.

<PAGE>

                  IN WITNESS WHEREOF, the Certificate Registrar has caused this
Certificate to be duly executed.

N.V., KEYCORP REAL ESTATE CAPITAL MARKETS, INC. OR ANY OF THEIR RESPECTIVE
AFFILIATES. NEITHER THIS CERTIFICATE NOR THE UNDERLYING MORTGAGE LOANS ARE

SOLELY FOR U.S. FEDERAL INCOME TAX PURPOSES, THIS CERTIFICATE IS A "REGULAR
INTEREST" IN A "REAL ESTATE MORTGAGE INVESTMENT CONDUIT" (A "REMIC") AS THOSE
TERMS ARE DEFINED, RESPECTIVELY, IN SECTIONS 860G AND 860D OF THE INTERNAL
REVENUE CODE OF 1986 (THE "CODE").

CERTIFICATE PRINCIPAL BALANCE OF THE CERTIFICATES RELATING TO SUCH COMPONENTS
AND BY CERTAIN LOSSES AND EXPENSES EXPERIENCED BY THE TRUST FUND WHICH ARE
ALLOCATED TO SUCH CERTIFICATES RELATING TO SUCH COMPONENTS AS SET FORTH IN THE
AGREEMENT, THE OUTSTANDING NOTIONAL AMOUNT HEREOF AT ANY TIME MAY BE LESS THAN
THE AMOUNT SHOWN ABOVE.

                  This certifies that Cede & Co. is the registered owner of the
Percentage Interest evidenced by this Class XP Certificate in that certain
beneficial ownership interest evidenced by all the Class XP Certificates in the
Trust Fund created pursuant to a Pooling and Servicing Agreement, dated as
specified above (the "Agreement"), among Merrill Lynch Mortgage Investors, Inc.
(herein called the "Depositor", which term includes any successor entity under
the Agreement), KeyCorp Real Estate Capital Markets, Inc. (herein called the
"Master Servicer", which term includes any successor entity under the
Agreement), ARCap Servicing, Inc. (herein called the "Special Servicer", which
term includes any

<PAGE>

successor entity under the Agreement), LaSalle Bank National Association (herein
called the "Trustee", which term includes any successor entity under the
Agreement), and ABN AMRO Bank N.V. (herein called the "Fiscal Agent", which term
includes any successor entity under the Agreement), a summary of certain of the
pertinent provisions of which is set forth hereafter. To the extent not defined
herein, the capitalized terms used herein have the respective meanings assigned
in the Agreement. This Certificate is issued under and is subject to the terms,
provisions and conditions of the Agreement, to which Agreement the Holder of
this Certificate by virtue of the acceptance hereof assents and by which such
Holder is bound.

                  Pursuant to the terms of the Agreement, distributions will be
made on the 12th day of any given month, or if the 12th day is not a Business
Day, on the next succeeding Business Day (each, a "Distribution Date"). With
respect to each Distribution Date, the Determination Date is the 4th Business
Day prior to the Distribution Date (each, a "Determination Date"). Distributions
will be made commencing on the first Distribution Date specified above, to the
Person in whose name this Certificate is registered at the close of business on
the last Business Day of the month immediately preceding the month of such
distribution (the "Record Date"), in an amount equal to the product of the
Percentage Interest evidenced by this Certificate and the amount required to be
distributed to the Holders of the Class XP Certificates on the applicable
Distribution Date pursuant to the Agreement. The Pass-Through Rate applicable to
each Component of the Class XP Certificates for each Distribution Date will be
as provided in the Agreement. All distributions made under the Agreement on the
Class XP Certificates will be made by the Trustee, by wire transfer of
immediately available funds to the account of the Person entitled thereto at a
bank or other entity having appropriate facilities therefor, if such
Certificateholder shall have provided the Trustee with wiring instructions no
less than five Business Days prior to the related Record Date (which wiring
instructions may be in the form of a standing order applicable to all subsequent
distributions), or otherwise by check mailed to the address of such
Certificateholder as it appears in the Certificate Register. Notwithstanding the
foregoing, the final distribution on this Certificate will be made in like
manner, but only upon presentation and surrender of this Certificate at the
offices of the Certificate Registrar or such other location specified in the
notice to the Holder hereof of such final distribution.

                  The Certificates are limited in right of distribution to
certain collections and recoveries respecting the Mortgage Loans, all as more
specifically set forth herein and in the Agreement. As provided in the
Agreement, withdrawals from the Certificate Account, the Distribution Account
and, if established, the REO Account may be made from time to time for purposes
other than, and, in certain cases, prior to, distributions to
Certificateholders, such purposes including the reimbursement of advances made,
or certain expenses incurred, with respect to the Mortgage Loans and the payment
of interest on such advances and expenses.

                  Interest accrued on this Certificate during an Interest
Accrual Period, plus any unpaid interest shortfall with respect to this
Certificate for any prior Distribution Date, if any, will be payable on the
related Distribution Date to the extent provided in the Agreement. The "Interest
Accrual Period" with respect to any Distribution Date and with respect to the
Class XP Certificates is the calendar month preceding the month in which such
Distribution Date occurs and is assumed to consist of 30 days.

<PAGE>

                  The Class XP Certificates are issuable in fully registered
form only without coupons in minimum denominations specified in the Agreement.
As provided in the Agreement and subject to certain limitations therein set
forth, Class XP Certificates are exchangeable for new Class XP Certificates in
authorized denominations evidencing the same aggregate Percentage Interest, as
requested by the Holder surrendering the same.

                  As provided in the Agreement and subject to certain
limitations therein set forth, the transfer of this Certificate is registrable
in the Certificate Register upon surrender of this Certificate for registration
of transfer at the offices of the Certificate Registrar, duly endorsed by, or
accompanied by a written instrument of transfer in the form satisfactory to the
Certificate Registrar duly executed by, the Holder hereof or his attorney duly
authorized in writing, and thereupon one or more new Class XP Certificates in
authorized denominations evidencing the same aggregate Percentage Interest will
be issued to the designated transferee or transferees.

                  With respect to any offer, sale, pledge or other transfer of
any Class XP Certificate, no such transfer of a Class XP Certificate shall be
made unless that transfer is made pursuant to an effective registration
statement under the Securities Act, and effective registration or qualification
under applicable state securities laws, or is made in a transaction which does
not require such registration or qualification. If such a transfer is to be made
without registration under the Securities Act (other than in connection with the
initial issuance thereof or the initial transfer thereof by the Depositor, the
Underwriters or their respective affiliates), then the Certificate Registrar
shall refuse to register such transfer unless it receives either: (i) a
certificate from the Certificateholder desiring to effect such transfer
substantially in the form attached as Exhibit E-1 to the Agreement, and a
certificate from such Certificateholder's prospective transferee substantially
in the form attached as either Exhibit E-2 (which relates to sales to QIBs in
reliance on Rule 144A) or Exhibit E-3 (which relates to sales to Institutional
Accredited Investors) to the Agreement; or (ii) an Opinion of Counsel
satisfactory to the Certificate Registrar to the effect that such transfer may
be made without registration under the Securities Act (which Opinion of Counsel
shall not be an expense of the Trust Fund or of the Depositor, the Master
Servicer, the Special Servicer, the Trustee or the Certificate Registrar in
their respective capacities as such), together with the written certification(s)
as to the facts surrounding such transfer from the Certificateholder desiring to
effect such transfer and/or such Certificateholder's prospective transferee on
which such Opinion of Counsel is based. None of the Depositor, the Trustee or
the Certificate Registrar is obligated to register or qualify the Class XP
Certificates under the Securities Act or any other securities law or to take any
action not otherwise required under the Agreement to permit the transfer of any
Class XP Certificate without registration or qualification. Any Class XP
Certificateholder desiring to effect such a transfer shall, and by the
acceptance of its Class XP Certificate agrees to, indemnify the Trustee, the
Certificate Registrar and the Depositor against any liability that may result if
the transfer is not so exempt or is not made in accordance with such federal and
state laws.

                  With respect to any offer, sale, pledge or other transfer of
any Class XP Certificate that constitutes a Class of Book-Entry Certificates, if
such a transfer is to be made without registration under the Securities Act,
such transfer will not be made unless the prospective transferee delivers to the
transferor (i) a certificate substantially in the form of

<PAGE>

Exhibit E-2 hereto and addressed to the transferor, upon or prior to such
transfer, or (ii) an opinion of counsel to the effect that such transferee is a
QIB and that such transfer may be made without registration under the Securities
Act, together with the written certification(s) as to the facts surrounding such
transfer, from the prospective transferor desiring to effect such transfer
and/or the prospective transferee, on which such opinion of counsel is based. In
any event, (a) each prospective transferor of such Class XP Certificate will be
deemed to have represented to the Trustee, the Depositor and the transferee of
such Certificate the information set forth on Exhibit E-1 upon or prior to such
transfer and (b) each prospective transferee of such Certificate will be deemed
to have represented to the Trustee, the Depositor and the transferor of such
Certificate the information set forth on Exhibit E-2 hereto.

                  An Institutional Accredited Investor (other than a QIB) may
not hold an interest in a Class XP Certificate in book-entry form and must hold
such interest in a Class XP Certificate in definitive form. Any transfer of such
Certificates will require, among other things described herein and in the
Agreement, delivery of the certificates and/or opinions required in connection
with the transfer of a Class XP Certificate held in a physical certificated
form, as set forth above.

                  No service charge will be imposed for any registration of
transfer or exchange of Class XP Certificates, but the Certificate Registrar may
require payment of a sum sufficient to cover any tax or other governmental
charge that may be imposed in connection with any transfer or exchange of Class
XP Certificates.

                  Notwithstanding the foregoing, for so long as this Certificate
is registered in the name of Cede & Co. or in such other name as is requested by
an authorized representative of DTC, transfers of interests in this Certificate
shall be made through the book-entry facilities of DTC.

                  The Depositor, the Master Servicer, the Special Servicer, the
Trustee, and the Certificate Registrar and any agent of the Depositor, the
Master Servicer, the Special Servicer, the Trustee, or the Certificate Registrar
may treat the Person in whose name this Certificate is registered as the owner
hereof for all purposes whatsoever and none of the Depositor, the Master
Servicer, the Special Servicer, the Trustee, the Certificate Registrar or any
such agent shall be affected by notice to the contrary.

                  The Trust Fund and the obligations created by the Agreement
shall terminate upon distribution (or provision for distribution) to the
Certificateholders of all amounts held by or on behalf of the Trustee and
required to be distributed to them pursuant to the Agreement following the
earlier to occur of (i) the final payment (or any advance with respect thereto)
or other liquidation of the last Mortgage Loan or REO Property remaining in the
Trust Fund, and (ii) the purchase by the Master Servicer, the Special Servicer
or the Majority Subordinate Certificateholder at a price determined as provided
in the Agreement of all Mortgage Loans and each REO Property remaining in the
Trust Fund. The Agreement permits, but does not require, the Master Servicer,
the Special Servicer or the Majority Subordinate Certificateholder to

<PAGE>

purchase from the Trust Fund all Mortgage Loans and each REO Property remaining
therein. The exercise of such right will effect early retirement of the Class XP
Certificates; however, such right to purchase is subject to the aggregate Stated
Principal Balance of the Mortgage Pool at the time of purchase being less than
1% of the aggregate Stated Principal Balance of the Mortgage Loans as of the
Closing Date specified on the face hereof.

                  The Agreement permits, with certain exceptions therein
provided, the amendment thereof and the modification of the rights and
obligations of the Depositor, the Master Servicer, the Special Servicer and the
Trustee and the rights of the Certificateholders under the Agreement at any time
by the Depositor, the Master Servicer, the Special Servicer, and the Trustee
with the consent of the Holders of Certificates entitled to at least 51% of the
Voting Rights allocated to the affected Classes. Any such consent by the Holder
of this Certificate shall be conclusive and binding on such Holder and upon all
future Holders of this Certificate and of any Certificate issued upon the
transfer hereof or in exchange herefor or in lieu hereof whether or not notation
of such consent is made upon this Certificate. The Agreement also permits the
amendment thereof, in certain limited circumstances, including any amendment
necessary to maintain the status of the Trust Fund (or designated portions
thereof) as consisting of three separate REMICs and a grantor trust, without the
consent of the Holders of any of the Certificates.

                  Unless the certificate of authentication hereon has been
executed by the Certificate Registrar, by manual signature, this Certificate
shall not be entitled to any benefit under the Agreement or be valid for any
purpose.

                  The registered Holder hereof, by its acceptance hereof, agrees
that it will look solely to the Trust Fund (to the extent of its rights therein)
for distributions hereunder.

                  This Certificate shall be construed in accordance with the
internal laws of the State of New York applicable to agreements made and to be
performed in said State, and the obligations, rights and remedies of the Holder
hereof shall be determined in accordance with such laws.

                  IN WITNESS WHEREOF, the Certificate Registrar has caused this
Certificate to be duly executed.

                  The Depositor, the Master Servicer, the Special Servicer, the
Trustee, and the Certificate Registrar and any agent of the Depositor, the
Master Servicer, the Special Servicer, the Trustee, or the Certificate Registrar
may treat the Person in whose name this Certificate is registered as the owner
hereof for all purposes whatsoever and none of the Depositor, the Master
Servicer, the Special Servicer, the Trustee, the Certificate Registrar or any
such agent shall be affected by notice to the contrary.

                  The Trust Fund and the obligations created by the Agreement
shall terminate upon distribution (or provision for distribution) to the

Trust Fund. The Agreement permits, but does not require, the Master Servicer,
the Special Servicer or the Majority Subordinate Certificateholder to purchase
from the Trust Fund all Mortgage Loans and each REO Property remaining therein.

1% of the aggregate Stated Principal Balance of the Mortgage Loans as of the
Closing Date specified on the face hereof.

                  The Agreement permits, with certain exceptions therein
provided, the amendment thereof and the modification of the rights and

Trustee and the rights of the Certificateholders under the Agreement at any time
by the Depositor, the Master Servicer, the Special Servicer and the Trustee with
the consent of the Holders of Certificates entitled to at least 51% of the
Voting Rights allocated to the affected Classes. Any such consent by the Holder
of this Certificate shall be conclusive and binding on such Holder and upon all
future Holders of this Certificate and of any Certificate issued upon the
transfer hereof or in exchange herefor or in lieu hereof whether or not notation
of such consent is made upon this Certificate. The Agreement also permits the
amendment thereof, in certain limited circumstances, including any amendment
necessary to maintain the status of the Trust Fund (or designated portions
thereof) as consisting of three separate REMICs and a grantor trust, without the
consent of the Holders of any of the Certificates.

                  Unless the certificate of authentication hereon has been
executed by the Certificate Registrar, by manual signature, this Certificate
shall not be entitled to any benefit under the Agreement or be valid for any
purpose.

performed in said State, and the obligations, rights and remedies of the Holder
hereof shall be determined in accordance with such laws.

Holder is bound.

                  Pursuant to the terms of the Agreement, distributions will be

Servicer", which term includes any successor entity under the Agreement), ARCap

successor entity under the Agreement), LaSalle Bank National Association (herein

pertinent provisions of which is set forth hereafter. To the extent not defined
herein, the capitalized terms used herein have the respective meanings assigned
in the Agreement. This Certificate is issued under and is subject to the terms,
provisions and conditions of the Agreement, to which Agreement the Holder of
this Certificate by virtue of the acceptance hereof assents and by which such
Holder is bound.

                  Pursuant to the terms of the Agreement, distributions will be
made on the 12th day of any given month, or if the 12th day is not a Business
Day, on the next succeeding Business Day (each, a "Distribution Date"). With
respect to each Distribution Date, the Determination Date is the 4th Business
Day prior to the Distribution Date (each, a "Determination Date"). Distributions
will be made commencing on the first Distribution Date specified above, to the
Person in whose name this Certificate is registered at the close of business on
the last Business Day of the month immediately preceding the month of such
distribution (the "Record Date"), in an amount equal to the product of the
Percentage Interest evidenced by this Certificate and the amount required to be
distributed to the Holders of the Class D Certificates on the applicable
Distribution Date pursuant to the Agreement. All distributions made under the
Agreement on the Class D Certificates will be made by the Trustee, by wire
transfer of immediately available funds to the account of the Person entitled
thereto at a bank or other entity having appropriate facilities therefor, if
such Certificateholder shall have provided the Trustee with wiring instructions
no less than five Business Days prior to the related Record Date (which wiring
instructions may be in the form of a standing order applicable to all subsequent
distributions), or otherwise by check mailed to the address of such
Certificateholder as it appears in the Certificate Register. Notwithstanding the

Fund Expense previously allocated to this Certificate) will be made in like

allocated to this Certificate, which reimbursement is to occur after the date on
which this Certificate is surrendered as contemplated by the preceding sentence,
will be made by check mailed to the address of the Holder that surrenders this
Certificate as such address last appears in the Certificate Register or to any
such other address of which the Trustee is subsequently notified in writing.

<PAGE>

                  The Certificates are limited in right of distribution to
certain collections and recoveries respecting the Mortgage Loans, all as more
specifically set forth herein and in the Agreement. As provided in the
Agreement, withdrawals from the Certificate Account, the Distribution Account
and, if established, the REO Account may be made from time to time for purposes
other than, and, in certain cases, prior to, distributions to
Certificateholders, such purposes including the reimbursement of advances made,
or certain expenses incurred, with respect to the Mortgage Loans and the payment
of interest on such advances and expenses.

                  Interest accrued on this Certificate during an Interest
Accrual Period, plus any unpaid interest shortfall with respect to this
Certificate for any prior Distribution Date, if any, will be payable on the
related Distribution Date to the extent provided in the Agreement. The "Interest
Accrual Period" with respect to any Distribution Date and with respect to the
Class D Certificates is the calendar month preceding the month in which such
Distribution Date occurs and is assumed to consist of 30 days.

                  Any distribution to the Holder of this Certificate in
reduction of the Certificate Principal Balance hereof is binding on such Holder
and all future Holders of this Certificate and any Certificate issued upon the
transfer hereof or in exchange herefor or in lieu hereof whether or not notation
of such distribution is made upon this Certificate.

                  The Class D Certificates are issuable in fully registered form
only without coupons in minimum denominations specified in the Agreement. As
provided in the Agreement and subject to certain limitations therein set forth,
Class D Certificates are exchangeable for new Class D Certificates in authorized
denominations evidencing the same aggregate Percentage Interest, as requested by
the Holder surrendering the same.

                  As provided in the Agreement and subject to certain
limitations therein set forth, the transfer of this Certificate is registrable
in the Certificate Register upon surrender of this Certificate for registration
of transfer at the offices of the Certificate Registrar, duly endorsed by, or
accompanied by a written instrument of transfer in the form satisfactory to the
Certificate Registrar duly executed by, the Holder hereof or his attorney duly
authorized in writing, and thereupon one or more new Class D Certificates in
authorized denominations evidencing the same aggregate Percentage Interest will
be issued to the designated transferee or transferees.

                  No service charge will be imposed for any registration of
transfer or exchange of Class D Certificates, but the Certificate Registrar may
require payment of a sum sufficient to cover any tax or other governmental
charge that may be imposed in connection with any transfer or exchange of Class
D Certificates.

                  Notwithstanding the foregoing, for so long as this Certificate
is registered in the name of Cede & Co. or in such other name as is requested by
an authorized representative of DTC, transfers of interests in this Certificate
shall be made through the book-entry facilities of DTC.

                  The Depositor, the Master Servicer, the Special Servicer, the
Trustee, and the Certificate Registrar and any agent of the Depositor, the
Master Servicer, the Special Servicer, the Trustee, or the Certificate Registrar
may treat the Person in whose name this Certificate is registered as the owner
hereof for all purposes whatsoever and none of the Depositor, the Master
Servicer, the Special Servicer, the Trustee, the Certificate Registrar or any
such agent shall be affected by notice to the contrary.

                  The Trust Fund and the obligations created by the Agreement
shall terminate upon distribution (or provision for distribution) to the
Certificateholders of all amounts held by or on behalf of the Trustee and
required to be distributed to them pursuant to the Agreement following the
earlier to occur of (i) the final payment (or any advance with respect thereto)
or other liquidation of the last Mortgage Loan or REO Property remaining in the
Trust Fund, and (ii) the purchase by the Special Servicer or the Majority
Subordinate Certificateholder at a price determined as provided in the Agreement
of all Mortgage Loans and each REO Property remaining in the Trust Fund. The
Agreement permits, but does not require, the Master Servicer, the Special
Servicer or the Majority Subordinate Certificateholder to purchase from the
Trust Fund all Mortgage Loans and each REO Property remaining therein. The
exercise of such right will effect early retirement of the Class D Certificates;
however, such right to purchase is subject to the aggregate Stated Principal
Balance of the Mortgage Pool at the time of purchase being less than 1% of the
aggregate Stated Principal Balance of the Mortgage Loans as of the Closing Date
specified on the face hereof.

                  The Agreement permits, with certain exceptions therein
provided, the amendment thereof and the modification of the rights and
obligations of the Depositor, the Master Servicer, the Special Servicer, and the
Trustee and the rights of the Certificateholders under the Agreement at any time
by the Depositor, the Master Servicer, the Special Servicer, and the Trustee
with the consent of the Holders of Certificates entitled to at least 51% of the
Voting Rights allocated to the affected Classes. Any such consent by the Holder
of this Certificate shall be conclusive and binding on such Holder and upon all
future Holders of this Certificate and of any Certificate issued upon the
transfer hereof or in exchange herefor or in lieu hereof whether or not notation
of such consent is made upon this Certificate. The Agreement also permits the
amendment thereof, in certain limited circumstances, including any amendment
necessary to maintain the status of the Trust Fund (or designated portions
thereof) as consisting of three separate REMICs and a grantor trust, without the
consent of the Holders of any of the Certificates.

                  Unless the certificate of authentication hereon has been
executed by the Certificate Registrar, by manual signature, this Certificate
shall not be entitled to any benefit under the Agreement or be valid for any
purpose.

                  The registered Holder hereof, by its acceptance hereof, agrees
that it will look solely to the Trust Fund (to the extent of its rights therein)
for distributions hereunder.

                  This Certificate shall be construed in accordance with the
internal laws of the State of New York applicable to agreements made and to be
performed in said State, and the

<PAGE>

obligations, rights and remedies of the Holder hereof shall be determined in
accordance with such laws.

                  IN WITNESS WHEREOF, the Certificate Registrar has caused this
Certificate to be duly executed.

require payment of a sum sufficient to cover any tax or other governmental
charge that may be imposed in connection with any transfer or exchange of Class
E Certificates.

                  Notwithstanding the foregoing, for so long as this Certificate
is registered in the name of Cede & Co. or in such other name as is requested by
an authorized representative of DTC, transfers of interests in this Certificate
shall be made through the book-entry facilities of DTC.

                  The Depositor, the Master Servicer, the Special Servicer, the
Trustee, and the Certificate Registrar and any agent of the Depositor, the
Master Servicer, the Special Servicer, the Trustee, or the Certificate Registrar
may treat the Person in whose name this Certificate is

<PAGE>

registered as the owner hereof for all purposes whatsoever and none of the
Depositor, the Master Servicer, the Special Servicer, the Trustee, the
Certificate Registrar or any such agent shall be affected by notice to the
contrary.

                  The Trust Fund and the obligations created by the Agreement
shall terminate upon distribution (or provision for distribution) to the
Certificateholders of all amounts held by or on behalf of the Trustee and
required to be distributed to them pursuant to the Agreement following the
earlier to occur of (i) the final payment (or any advance with respect thereto)
or other liquidation of the last Mortgage Loan or REO Property remaining in the
Trust Fund, and (ii) the purchase by the Master Servicer, the Special Servicer
or the Majority Subordinate Certificateholder at a price determined as provided
in the Agreement of all Mortgage Loans and each REO Property remaining in the
Trust Fund. The Agreement permits, but does not require, the Master Servicer,
the Special Servicer or the Majority Subordinate Certificateholder to purchase
from the Trust Fund all Mortgage Loans and each REO Property remaining therein.
The exercise of such right will effect early retirement of the Class E
Certificates; however, such right to purchase is subject to the aggregate Stated
Principal Balance of the Mortgage Pool at the time of purchase being less than
1% of the aggregate Stated Principal Balance of the Mortgage Loans as of the
Closing Date specified on the face hereof.

                  The Agreement permits, with certain exceptions therein
provided, the amendment thereof and the modification of the rights and
obligations of the Depositor, the Master Servicer, the Special Servicer, and the
Trustee and the rights of the Certificateholders under the Agreement at any time
by the Depositor, the Master Servicer, the Special Servicer, and the Trustee
with the consent of the Holders of Certificates entitled to at least 51% of the
Voting Rights allocated to the affected Classes. Any such consent by the Holder
of this Certificate shall be conclusive and binding on such Holder and upon all
future Holders of this Certificate and of any Certificate issued upon the
transfer hereof or in exchange herefor or in lieu hereof whether or not notation
of such consent is made upon this Certificate. The Agreement also permits the
amendment thereof, in certain limited circumstances, including any amendment
necessary to maintain the status of the Trust Fund (or designated portions
thereof) as consisting of three separate REMICs and a grantor trust, without the
consent of the Holders of any of the Certificates.

                  Unless the certificate of authentication hereon has been
executed by the Certificate Registrar, by manual signature, this Certificate
shall not be entitled to any benefit under the Agreement or be valid for any
purpose.

                  The registered Holder hereof, by its acceptance hereof, agrees
that it will look solely to the Trust Fund (to the extent of its rights therein)
for distributions hereunder.

                  This Certificate shall be construed in accordance with the
internal laws of the State of New York applicable to agreements made and to be
performed in said State, and the obligations, rights and remedies of the Holder
hereof shall be determined in accordance with such laws.

Certificate to be duly executed.

<PAGE>

REFERRED TO HEREIN. ACCORDINGLY, THE OUTSTANDING CERTIFICATE PRINCIPAL BALANCE

                  This certifies that Cede & Co. is the registered owner of the
Percentage Interest evidenced by this Class F Certificate (obtained by dividing
the principal amount of this Class F Certificate (its "Certificate Principal
Balance") as of the Closing Date by the aggregate principal amount of all the
Class F Certificates (their "Class Principal Balance") as of the Closing Date)
in that certain beneficial ownership interest evidenced by all the Class F

Agreement, dated as specified above (the "Agreement"), among Merrill Lynch

successor entity under the Agreement), KeyCorp Real Estate Capital Markets, Inc.
(herein called the "Master Servicer", which term includes any successor entity
under the Agreement), ARCap Servicing, Inc. (herein called the "Special
Servicer", which term includes any successor entity under the Agreement),
LaSalle Bank National Association (herein called the "Trustee", which term

is set forth hereafter. To the extent not defined herein, the capitalized terms
used herein have the respective meanings assigned in the Agreement. This
Certificate is issued under and is subject to the terms, provisions and
conditions of the Agreement, to which Agreement the Holder of this Certificate
by virtue of the acceptance hereof assents and by which such Holder is bound.

                  Pursuant to the terms of the Agreement, distributions will be
made on the 12th day of any given month, or if the 12th day is not a Business
Day, on the next succeeding Business Day (each, a "Distribution Date"). With
respect to each Distribution Date, the Determination Date is the 4th Business
Day prior to the Distribution Date (each, a "Determination Date"). Distributions
will be made commencing on the first Distribution Date specified above, to the
Person in whose name this Certificate is registered at the close of business on
the last Business Day of the month immediately preceding the month of such
distribution (the "Record Date"), in an amount equal to the product of the
Percentage Interest evidenced by this Certificate and the amount required to be
distributed to the Holders of the Class F Certificates on the applicable
Distribution Date pursuant to the Agreement. All distributions made under the
Agreement on the Class F Certificates will be made by the Trustee, by wire
transfer of immediately available funds to the account of the Person entitled
thereto at a bank or other entity having appropriate facilities therefor, if
such Certificateholder shall have provided the Trustee with wiring instructions
no less than five Business Days prior to the related Record Date (which wiring
instructions may be in the form of a standing order applicable to all subsequent
distributions), or otherwise by check mailed to the address of such
Certificateholder as it appears in the Certificate Register. Notwithstanding the
foregoing, the final distribution on this Certificate (determined without regard
to any possible future reimbursement of any Realized Loss or Additional Trust
Fund Expense previously allocated to this Certificate) will be made in like
manner, but only upon presentation and surrender of this Certificate at the
offices of the Certificate Registrar or such other location specified in the
notice to the Holder hereof of such final distribution. Also notwithstanding the
foregoing, any distribution that may be made with respect to this Certificate

<PAGE>

in reimbursement of any Realized Loss or Additional Trust Fund Expense
previously allocated to this Certificate, which reimbursement is to occur after
the date on which this Certificate is surrendered as contemplated by the
preceding sentence, will be made by check mailed to the address of the Holder
that surrenders this Certificate as such address last appears in the Certificate
Register or to any such other address of which the Trustee is subsequently
notified in writing.

                  The Certificates are limited in right of distribution to
certain collections and recoveries respecting the Mortgage Loans, all as more
specifically set forth herein and in the Agreement. As provided in the
Agreement, withdrawals from the Certificate Account, the Distribution Account
and, if established, the REO Account may be made from time to time for purposes
other than, and, in certain cases, prior to, distributions to
Certificateholders, such purposes including the reimbursement of advances made,
or certain expenses incurred, with respect to the Mortgage Loans and the payment
of interest on such advances and expenses.

                  Interest accrued on this Certificate during an Interest
Accrual Period, plus any unpaid interest shortfall with respect to this
Certificate for any prior Distribution Date, if any, will be payable on the
related Distribution Date to the extent provided in the Agreement. The "Interest
Accrual Period" with respect to any Distribution Date and with respect to the
Class F Certificates is the calendar month preceding the month in which such
Distribution Date occurs and is assumed to consist of 30 days.

                  Any distribution to the Holder of this Certificate in
reduction of the Certificate Principal Balance hereof is binding on such Holder
and all future Holders of this Certificate and any Certificate issued upon the
transfer hereof or in exchange herefor or in lieu hereof whether or not notation
of such distribution is made upon this Certificate.

                  The Class F Certificates are issuable in fully registered form
only without coupons in minimum denominations specified in the Agreement. As
provided in the Agreement and subject to certain limitations therein set forth,
Class F Certificates are exchangeable for new Class F Certificates in authorized
denominations evidencing the same aggregate Percentage Interest, as requested by
the Holder surrendering the same.

                  As provided in the Agreement and subject to certain
limitations therein set forth, the transfer of this Certificate is registrable
in the Certificate Register upon surrender of this Certificate for registration
of transfer at the offices of the Certificate Registrar, duly endorsed by, or
accompanied by a written instrument of transfer in the form satisfactory to the
Certificate Registrar duly executed by, the Holder hereof or his attorney duly
authorized in writing, and thereupon one or more new Class F Certificates in
authorized denominations evidencing the same aggregate Percentage Interest will
be issued to the designated transferee or transferees.

                  With respect to any offer, sale, pledge or other transfer of
any Class F Certificate, no such transfer of a Class F Certificate shall be made
unless that transfer is made pursuant to an effective registration statement
under the Securities Act, and effective registration or qualification under
applicable state securities laws, or is made in a transaction which does not

<PAGE>

require such registration or qualification. If such a transfer is to be made
without registration under the Securities Act (other than in connection with the
initial issuance thereof or the initial transfer thereof by the Depositor, the
Underwriters or their respective affiliates), then the Certificate Registrar
shall refuse to register such transfer unless it receives either: (i) a
certificate from the Certificateholder desiring to effect such transfer
substantially in the form attached as Exhibit E-1 to the Agreement, and a
certificate from such Certificateholder's prospective transferee substantially
in the form attached as either Exhibit E-2 (which relates to sales to QIBs in
reliance on Rule 144A) or Exhibit E-3 (which relates to sales to Institutional
Accredited Investors) to the Agreement; or (ii) an Opinion of Counsel
satisfactory to the Certificate Registrar to the effect that such transfer may
be made without registration under the Securities Act (which Opinion of Counsel
shall not be an expense of the Trust Fund or of the Depositor, the Master
Servicer, the Special Servicer, the Trustee or the Certificate Registrar in
their respective capacities as such), together with the written certification(s)
as to the facts surrounding such transfer from the Certificateholder desiring to
effect such transfer and/or such Certificateholder's prospective transferee on
which such Opinion of Counsel is based. None of the Depositor, the Trustee or
the Certificate Registrar is obligated to register or qualify the Class F
Certificates under the Securities Act or any other securities law or to take any
action not otherwise required under the Agreement to permit the transfer of any
Class F Certificate without registration or qualification. Any Class F
Certificateholder desiring to effect such a transfer shall, and by the
acceptance of its Class F Certificate agrees to, indemnify the Trustee, the
Certificate Registrar and the Depositor against any liability that may result if
the transfer is not so exempt or is not made in accordance with such federal and
state laws.

                  With respect to any offer, sale, pledge or other transfer of
any Class F Certificate that constitutes a Class of Book-Entry Certificates, if
such a transfer is to be made without registration under the Securities Act,
such transfer will not be made unless the prospective transferee delivers to the
transferor (i) a certificate substantially in the form of Exhibit E-2 hereto and
addressed to the transferor, upon or prior to such transfer, or (ii) an opinion
of counsel to the effect that such transferee is a QIB and that such transfer
may be made without registration under the Securities Act, together with the
written certification(s) as to the facts surrounding such transfer, from the
prospective transferor desiring to effect such transfer and/or the prospective
transferee, on which such opinion of counsel is based. In any event, (a) each
prospective transferor of such Class F Certificate will be deemed to have
represented to the Trustee, the Depositor and the transferee of such Certificate
the information set forth on Exhibit E-1 upon or prior to such transfer and (b)
each prospective transferee of such Certificate will be deemed to have
represented to the Trustee, the Depositor and the transferor of such Certificate
the information set forth on Exhibit E-2 hereto.

                  An Institutional Accredited Investor (other than a QIB) may
not hold an interest in a Class F Certificate in book-entry form and must hold
such interest in a Class F Certificate in definitive form. Any transfer of such
Certificates will require, among other things described herein and in the
Agreement, delivery of the certificates and/or opinions required in connection
with the transfer of a Class F Certificate held in a physical certificated form,
as set forth above.

<PAGE>

                  No service charge will be imposed for any registration of
transfer or exchange of Class F Certificates, but the Certificate Registrar may
require payment of a sum sufficient to cover any tax or other governmental
charge that may be imposed in connection with any transfer or exchange of Class
F Certificates.

                  Notwithstanding the foregoing, for so long as this Certificate
is registered in the name of Cede & co. or in such other name as is requested by
an authorized representative of DTC, transfers of interests in this Certificate
shall be made through the book-entry facilities of DTC.

                  The Depositor, the Master Servicer, the Special Servicer, the
Trustee, and the Certificate Registrar and any agent of the Depositor, the
Master Servicer, the Special Servicer, the Trustee, or the Certificate Registrar
may treat the Person in whose name this Certificate is registered as the owner
hereof for all purposes whatsoever and none of the Depositor, the Master
Servicer, the Special Servicer, the Trustee, the Certificate Registrar or any
such agent shall be affected by notice to the contrary.

                  The Trust Fund and the obligations created by the Agreement
shall terminate upon distribution (or provision for distribution) to the
Certificateholders of all amounts held by or on behalf of the Trustee and
required to be distributed to them pursuant to the Agreement following the
earlier to occur of (i) the final payment (or any advance with respect thereto)
or other liquidation of the last Mortgage Loan or REO Property remaining in the
Trust Fund, and (ii) the purchase by the Master Servicer, the Special Servicer
or the Majority Subordinate Certificateholder at a price determined as provided
in the Agreement of all Mortgage Loans and each REO Property remaining in the
Trust Fund. The Agreement permits, but does not require, the Master Servicer,
the Special Servicer or the Majority Subordinate Certificateholder to purchase
from the Trust Fund all Mortgage Loans and each REO Property remaining therein.
The exercise of such right will effect early retirement of the Class F
Certificates; however, such right to purchase is subject to the aggregate Stated
Principal Balance of the Mortgage Pool at the time of purchase being less than
1% of the aggregate Stated Principal Balance of the Mortgage Loans as of the
Closing Date specified on the face hereof.

                  The Agreement permits, with certain exceptions therein
provided, the amendment thereof and the modification of the rights and
obligations of the Depositor, the Master Servicer, the Special Servicer, and the
Trustee and the rights of the Certificateholders under the Agreement at any time
by the Depositor, the Master Servicer, the Special Servicer, and the Trustee
with the consent of the Holders of Certificates entitled to at least 51% of the
Voting Rights allocated to the affected Classes. Any such consent by the Holder
of this Certificate shall be conclusive and binding on such Holder and upon all
future Holders of this Certificate and of any Certificate issued upon the
transfer hereof or in exchange herefor or in lieu hereof whether or not notation
of such consent is made upon this Certificate. The Agreement also permits the
amendment thereof, in certain limited circumstances, including any amendment
necessary to maintain the status of the Trust Fund (or designated portions
thereof) as consisting of three separate REMICs and a grantor trust, without the
consent of the Holders of any of the Certificates.

                  This certifies that Cede & Co. is the registered owner of the
Percentage Interest evidenced by this Class G Certificate (obtained by dividing
the principal amount of this Class G Certificate (its "Certificate Principal
Balance") as of the Closing Date by the aggregate principal amount of all the
Class G Certificates (their "Class Principal Balance") as of the Closing Date)
in that certain beneficial ownership interest evidenced by all the Class G
Certificates in the Trust Fund created pursuant to a Pooling and Servicing
Agreement, dated as specified above (the "Agreement"), among Merrill Lynch
Mortgage Investors, Inc. (herein called the "Depositor", which term includes any
successor entity under the Agreement), KeyCorp Real Estate Capital Markets, Inc.
(herein called the "Master Servicer", which term includes any successor entity
under the Agreement), ARCap Servicing, Inc. (herein called the "Special
Servicer", which term includes any successor entity under the Agreement),
LaSalle Bank National Association (herein called the "Trustee", which term

(herein called the "Fiscal Agent", which term includes any successor entity
under the Agreement), a summary of certain of the pertinent provisions of which
is set forth hereafter. To the extent not defined herein, the capitalized terms
used herein have the respective meanings assigned in the Agreement. This
Certificate is issued under and is subject to the terms, provisions and
conditions of the Agreement, to which Agreement the Holder of this Certificate
by virtue of the acceptance hereof assents and by which such Holder is bound.

                  Pursuant to the terms of the Agreement, distributions will be
made on the 12th day of any given month, or if the 12th day is not a Business
Day, on the next succeeding Business Day (each, a "Distribution Date"). With
respect to each Distribution Date, the Determination Date is the 4th Business
Day prior to the Distribution Date (each, a "Determination Date"). Distributions
will be made commencing on the first Distribution Date specified above, to the
Person in whose name this Certificate is registered at the close of business on
the last Business Day of the month immediately preceding the month of such
distribution (the "Record Date"), in an amount equal to the product of the
Percentage Interest evidenced by this Certificate and the amount required to be
distributed to the Holders of the Class G Certificates on the applicable
Distribution Date pursuant to the Agreement. All distributions made under the
Agreement on the Class G Certificates will be made by the Trustee, by wire
transfer of immediately available funds to the account of the Person entitled
thereto at a bank or other entity having appropriate facilities therefor, if
such Certificateholder shall have provided the Trustee with wiring instructions
no less than five Business Days prior to the related Record Date (which wiring
instructions may be in the form of a standing order applicable to all subsequent
distributions), or otherwise by check mailed to the address of such
Certificateholder as it appears in the Certificate Register. Notwithstanding the
foregoing, the final distribution on this Certificate (determined without regard
to any possible future reimbursement of any Realized Loss or Additional Trust
Fund Expense previously allocated to this Certificate) will be made in like
manner, but only upon presentation and surrender of this Certificate at the
offices of the Certificate Registrar or such

<PAGE>

other location specified in the notice to the Holder hereof of such final
distribution. Also notwithstanding the foregoing, any distribution that may be
made with respect to this Certificate in reimbursement of any Realized Loss or
Additional Trust Fund Expense previously allocated to this Certificate, which
reimbursement is to occur after the date on which this Certificate is
surrendered as contemplated by the preceding sentence, will be made by check
mailed to the address of the Holder that surrenders this Certificate as such
address last appears in the Certificate Register or to any such other address of
which the Trustee is subsequently notified in writing.

                  The Certificates are limited in right of distribution to
certain collections and recoveries respecting the Mortgage Loans, all as more
specifically set forth herein and in the Agreement. As provided in the
Agreement, withdrawals from the Certificate Account, the Distribution Account
and, if established, the REO Account may be made from time to time for purposes
other than, and, in certain cases, prior to, distributions to
Certificateholders, such purposes including the reimbursement of advances made,
or certain expenses incurred, with respect to the Mortgage Loans and the payment
of interest on such advances and expenses.

                  Interest accrued on this Certificate during an Interest
Accrual Period, plus any unpaid interest shortfall with respect to this
Certificate for any prior Distribution Date, if any, will be payable on the
related Distribution Date to the extent provided in the Agreement. The "Interest
Accrual Period" with respect to any Distribution Date and with respect to the
Class G Certificates is the calendar month preceding the month in which such
Distribution Date occurs and is assumed to consist of 30 days.

                  Any distribution to the Holder of this Certificate in
reduction of the Certificate Principal Balance hereof is binding on such Holder
and all future Holders of this Certificate and any Certificate issued upon the
transfer hereof or in exchange herefor or in lieu hereof whether or not notation
of such distribution is made upon this Certificate.

                  The Class G Certificates are issuable in fully registered form
only without coupons in minimum denominations specified in the Agreement. As
provided in the Agreement and subject to certain limitations therein set forth,
Class G Certificates are exchangeable for new Class G Certificates in authorized
denominations evidencing the same aggregate Percentage Interest, as requested by
the Holder surrendering the same.

                  As provided in the Agreement and subject to certain
limitations therein set forth, the transfer of this Certificate is registrable
in the Certificate Register upon surrender of this Certificate for registration
of transfer at the offices of the Certificate Registrar, duly endorsed by, or
accompanied by a written instrument of transfer in the form satisfactory to the
Certificate Registrar duly executed by, the Holder hereof or his attorney duly
authorized in writing, and thereupon one or more new Class G Certificates in
authorized denominations evidencing the same aggregate Percentage Interest will
be issued to the designated transferee or transferees.

                  With respect to any offer, sale, pledge or other transfer of
any Class G Certificate, no such transfer of a Class G Certificate shall be made
unless that transfer is made pursuant to an

<PAGE>

effective registration statement under the Securities Act, and effective
registration or qualification under applicable state securities laws, or is made
in a transaction which does not require such registration or qualification. If
such a transfer is to be made without registration under the Securities Act
(other than in connection with the initial issuance thereof or the initial
transfer thereof by the Depositor, the Underwriters or their respective
affiliates), then the Certificate Registrar shall refuse to register such
transfer unless it receives either: (i) a certificate from the Certificateholder
desiring to effect such transfer substantially in the form attached as Exhibit
E-1 to the Agreement, and a certificate from such Certificateholder's
prospective transferee substantially in the form attached as either Exhibit E-2
(which relates to sales to QIBs in reliance on Rule 144A) or Exhibit E-3 (which
relates to sales to Institutional Accredited Investors) to the Agreement; or
(ii) an Opinion of Counsel satisfactory to the Certificate Registrar to the
effect that such transfer may be made without registration under the Securities
Act (which Opinion of Counsel shall not be an expense of the Trust Fund or of
the Depositor, the Master Servicer, the Special Servicer, the Trustee or the
Certificate Registrar in their respective capacities as such), together with the
written certification(s) as to the facts surrounding such transfer from the
Certificateholder desiring to effect such transfer and/or such
Certificateholder's prospective transferee on which such Opinion of Counsel is
based. None of the Depositor, the Trustee or the Certificate Registrar is
obligated to register or qualify the Class G Certificates under the Securities
Act or any other securities law or to take any action not otherwise required
under the Agreement to permit the transfer of any Class G Certificate without
registration or qualification. Any Class G Certificateholder desiring to effect
such a transfer shall, and by the acceptance of its Class G Certificate agrees
to, indemnify the Trustee, the Certificate Registrar and the Depositor against
any liability that may result if the transfer is not so exempt or is not made in
accordance with such federal and state laws.

                  With respect to any offer, sale, pledge or other transfer of
any Class G Certificate that constitutes a Class of Book-Entry Certificates, if
such a transfer is to be made without registration under the Securities Act,
such transfer will not be made unless the prospective transferee delivers to the
transferor (i) a certificate substantially in the form of Exhibit E-2 hereto and
addressed to the transferor, upon or prior to such transfer, or (ii) an opinion
of counsel to the effect that such transferee is a QIB and that such transfer
may be made without registration under the Securities Act, together with the
written certification(s) as to the facts surrounding such transfer, from the
prospective transferor desiring to effect such transfer and/or the prospective
transferee, on which such opinion of counsel is based. In any event, (a) each
prospective transferor of such Class G Certificate will be deemed to have
represented to the Trustee, the Depositor and the transferee of such Certificate
the information set forth on Exhibit E-1 upon or prior to such transfer and (b)
each prospective transferee of such Certificate will be deemed to have
represented to the Trustee, the Depositor and the transferor of such Certificate
the information set forth on Exhibit E-2 hereto.

                  An Institutional Accredited Investor (other than a QIB) may
not hold an interest in a Class G Certificate in book-entry form and must hold
such interest in a Class G Certificate in definitive form. Any transfer of such
Certificates will require, among other things described herein and in the
Agreement, delivery of the certificates and/or opinions required in connection
with the transfer of a Class G Certificate held in a physical certificated form,
as set forth above.

<PAGE>

                  No service charge will be imposed for any registration of
transfer or exchange of Class G Certificates, but the Certificate Registrar may
require payment of a sum sufficient to cover any tax or other governmental
charge that may be imposed in connection with any transfer or exchange of Class
G Certificates.

                  Notwithstanding the foregoing, for so long as this Certificate
is registered in the name of Cede & Co. or in such other name as is requested by
an authorized representative of DTC, transfers of interests in this Certificate
shall be made through the book-entry facilities of DTC.

                  The Depositor, the Master Servicer, the Special Servicer, the
Trustee, and the Certificate Registrar and any agent of the Depositor, the
Master Servicer, the Special Servicer, the Trustee, or the Certificate Registrar
may treat the Person in whose name this Certificate is registered as the owner
hereof for all purposes whatsoever and none of the Depositor, the Master
Servicer, the Special Servicer, the Trustee, the Certificate Registrar or any
such agent shall be affected by notice to the contrary.

                  The Trust Fund and the obligations created by the Agreement
shall terminate upon distribution (or provision for distribution) to the
Certificateholders of all amounts held by or on behalf of the Trustee and
required to be distributed to them pursuant to the Agreement following the
earlier to occur of (i) the final payment (or any advance with respect thereto)
or other liquidation of the last Mortgage Loan or REO Property remaining in the
Trust Fund, and (ii) the purchase by the Master Servicer, the Special Servicer
or the Majority Subordinate Certificateholder at a price determined as provided
in the Agreement of all Mortgage Loans and each REO Property remaining in the
Trust Fund. The Agreement permits, but does not require, the Master Servicer,
the Special Servicer or the Majority Subordinate Certificateholder to purchase
from the Trust Fund all Mortgage Loans and each REO Property remaining therein.
The exercise of such right will effect early retirement of the Class G
Certificates; however, such right to purchase is subject to the aggregate Stated
Principal Balance of the Mortgage Pool at the time of purchase being less than
1% of the aggregate Stated Principal Balance of the Mortgage Loans as of the
Closing Date specified on the face hereof.

                  The Agreement permits, with certain exceptions therein
provided, the amendment thereof and the modification of the rights and
obligations of the Depositor, the Master Servicer, the Special Servicer, and the
Trustee and the rights of the Certificateholders under the Agreement at any time
by the Depositor, the Master Servicer, the Special Servicer and the Trustee with
the consent of the Holders of Certificates entitled to at least 51% of the
Voting Rights allocated to the affected Classes. Any such consent by the Holder
of this Certificate shall be conclusive and binding on such Holder and upon all
future Holders of this Certificate and of any Certificate issued upon the
transfer hereof or in exchange herefor or in lieu hereof whether or not notation
of such consent is made upon this Certificate. The Agreement also permits the
amendment thereof, in certain limited circumstances, including any amendment
necessary to maintain the status of the Trust Fund (or designated portions
thereof) as consisting of three

<PAGE>

separate REMICs and a grantor trust, without the consent of the Holders of any
of the Certificates.

                  Unless the certificate of authentication hereon has been
executed by the Certificate Registrar, by manual signature, this Certificate
shall not be entitled to any benefit under the Agreement or be valid for any
purpose.

                  The registered Holder hereof, by its acceptance hereof, agrees
that it will look solely to the Trust Fund (to the extent of its rights therein)
for distributions hereunder.

                  This Certificate shall be construed in accordance with the
internal laws of the State of New York applicable to agreements made and to be
performed in said State, and the obligations, rights and remedies of the Holder
hereof shall be determined in accordance with such laws.

                  IN WITNESS WHEREOF, the Certificate Registrar has caused this
Certificate to be duly executed.

                  This certifies that Cede & Co. is the registered owner of the
Percentage Interest evidenced by this Class H Certificate (obtained by dividing
the principal amount of this Class H Certificate (its "Certificate Principal
Balance") as of the Closing Date by the aggregate principal amount of all the
Class H Certificates (their "Class Principal Balance") as of the Closing Date)
in that certain beneficial ownership interest evidenced by all the Class H
Certificates in the Trust Fund created pursuant to a Pooling and Servicing
Agreement, dated as specified above (the "Agreement"), among Merrill Lynch
Mortgage Investors, Inc. (herein called the "Depositor", which term includes any
successor entity under the Agreement), KeyCorp Real Estate Capital Markets, Inc.
(herein called the "Master Servicer", which term includes any successor entity
under the Agreement), ARCap Servicing, Inc. (herein called the "Special
Servicer", which term includes any successor entity under the Agreement),
LaSalle Bank National Association (herein called the "Trustee", which term
includes any successor entity under the Agreement), and ABN AMRO Bank N.V.
(herein called the "Fiscal Agent", which term includes any successor entity
under the Agreement), a summary of certain of the pertinent provisions of which
is set forth hereafter. To the extent not defined herein, the capitalized terms
used herein have the respective meanings assigned in the Agreement. This
Certificate is issued under and is subject to the terms, provisions and
conditions of the Agreement, to which Agreement the Holder of this Certificate
by virtue of the acceptance hereof assents and by which such Holder is bound.

                  Pursuant to the terms of the Agreement, distributions will be
made on the 12th day of any given month, or if the 12th day is not a Business
Day, on the next succeeding Business Day (each, a "Distribution Date"). With
respect to each Distribution Date, the Determination Date is the 4th Business
Day prior to the Distribution Date (each, a "Determination Date"). Distributions
will be made commencing on the first Distribution Date specified above, to the
Person in whose name this Certificate is registered at the close of business on
the last Business Day of the month immediately preceding the month of such
distribution (the "Record Date"), in an amount equal to the product of the
Percentage Interest evidenced by this Certificate and the amount required to be
distributed to the Holders of the Class H Certificates on the applicable
Distribution Date pursuant to the Agreement. All distributions made under the
Agreement on the Class H Certificates will be made by the Trustee, by wire
transfer of immediately available funds to the account of the Person entitled
thereto at a bank or other entity having appropriate facilities therefor, if
such Certificateholder shall have provided the Trustee with wiring instructions
no less than five Business Days prior to the related Record Date (which wiring
instructions may be in the form of a standing order applicable to all subsequent
distributions), or otherwise by check mailed to the address of such
Certificateholder as it appears in the Certificate Register. Notwithstanding the
foregoing, the final distribution on this Certificate (determined without regard
to any possible future reimbursement of any Realized Loss or Additional Trust
Fund Expense previously allocated to this Certificate) will be made in like
manner, but only upon presentation and surrender of this Certificate at the
offices of the Certificate Registrar or such

<PAGE>

other location specified in the notice to the Holder hereof of such final
distribution. Also notwithstanding the foregoing, any distribution that may be
made with respect to this Certificate in reimbursement of any Realized Loss or
Additional Trust Fund Expense previously allocated to this Certificate, which
reimbursement is to occur after the date on which this Certificate is
surrendered as contemplated by the preceding sentence, will be made by check
mailed to the address of the Holder that surrenders this Certificate as such
address last appears in the Certificate Register or to any such other address of
which the Trustee is subsequently notified in writing.

                  The Certificates are limited in right of distribution to
certain collections and recoveries respecting the Mortgage Loans, all as more
specifically set forth herein and in the Agreement. As provided in the
Agreement, withdrawals from the Certificate Account, the Distribution Account
and, if established, the REO Account may be made from time to time for purposes
other than, and, in certain cases, prior to, distributions to
Certificateholders, such purposes including the reimbursement of advances made,
or certain expenses incurred, with respect to the Mortgage Loans and the payment
of interest on such advances and expenses.

                  Interest accrued on this Certificate during an Interest
Accrual Period, plus any unpaid interest shortfall with respect to this
Certificate for any prior Distribution Date, if any, will be payable on the
related Distribution Date to the extent provided in the Agreement. The "Interest
Accrual Period" with respect to any Distribution Date and with respect to the
Class H Certificates is the calendar month preceding the month in which such
Distribution Date occurs and is assumed to consist of 30 days.

                  Any distribution to the Holder of this Certificate in
reduction of the Certificate Principal Balance hereof is binding on such Holder
and all future Holders of this Certificate and any Certificate issued upon the
transfer hereof or in exchange herefor or in lieu hereof whether or not notation
of such distribution is made upon this Certificate.

                  The Class H Certificates are issuable in fully registered form
only without coupons in minimum denominations specified in the Agreement. As
provided in the Agreement and subject to certain limitations therein set forth,
Class H Certificates are exchangeable for new Class H Certificates in authorized
denominations evidencing the same aggregate Percentage Interest, as requested by
the Holder surrendering the same.

                  As provided in the Agreement and subject to certain
limitations therein set forth, the transfer of this Certificate is registrable
in the Certificate Register upon surrender of this Certificate for registration
of transfer at the offices of the Certificate Registrar, duly endorsed by, or
accompanied by a written instrument of transfer in the form satisfactory to the
Certificate Registrar duly executed by, the Holder hereof or his attorney duly
authorized in writing, and thereupon one or more new Class H Certificates in
authorized denominations evidencing the same aggregate Percentage Interest will
be issued to the designated transferee or transferees.

                  With respect to any offer, sale, pledge or other transfer of
any Class H Certificate, no such transfer of a Class H Certificate shall be made
unless that transfer is made pursuant to an

<PAGE>

effective registration statement under the Securities Act, and effective
registration or qualification under applicable state securities laws, or is made
in a transaction which does not require such registration or qualification. If
such a transfer is to be made without registration under the Securities Act
(other than in connection with the initial issuance thereof or the initial
transfer thereof by the Depositor, the Underwriters or their respective
affiliates), then the Certificate Registrar shall refuse to register such
transfer unless it receives either: (i) a certificate from the Certificateholder
desiring to effect such transfer substantially in the form attached as Exhibit
E-1 to the Agreement, and a certificate from such Certificateholder's
prospective transferee substantially in the form attached as either Exhibit E-2
(which relates to sales to QIBs in reliance on Rule 144A) or Exhibit E-3 (which
relates to sale to Institutional Accredited Investors) to the Agreement; or (ii)
an Opinion of Counsel satisfactory to the Certificate Registrar to the effect
that such transfer may be made without registration under the Securities Act
(which Opinion of Counsel shall not be an expense of the Trust Fund or of the
Depositor, the Master Servicer, the Special Servicer, the Trustee or the
Certificate Registrar in their respective capacities as such), together with the
written certification(s) as to the facts surrounding such transfer from the
Certificateholder desiring to effect such transfer and/or such
Certificateholder's prospective transferee on which such Opinion of Counsel is
based. None of the Depositor, the Trustee or the Certificate Registrar is
obligated to register or qualify the Class H Certificates under the Securities
Act or any other securities law or to take any action not otherwise required
under the Agreement to permit the transfer of any Class H Certificate without
registration or qualification. Any Class H Certificateholder desiring to effect
such a transfer shall, and by the acceptance of its Class H Certificate agrees
to, indemnify the Trustee, the Certificate Registrar and the Depositor against
any liability that may result if the transfer is not so exempt or is not made in
accordance with such federal and state laws.

                  With respect to any offer, sale, pledge or other transfer of
any Class H Certificate that constitutes a Class of Book-Entry Certificates, if
such a transfer is to be made without registration under the Securities Act,
such transfer will not be made unless the prospective transferee delivers to the
transferor (i) a certificate substantially in the form of Exhibit E-2 hereto and
addressed to the transferor, upon or prior to such transfer, or (ii) an opinion
of counsel to the effect that such transferee is a QIB and that such transfer
may be made without registration under the Securities Act, together with the
written certification(s) as to the facts surrounding such transfer, from the
prospective transferor desiring to effect such transfer and/or the prospective
transferee, on which such opinion of counsel is based. In any event, (a) each
prospective transferor of such Class H Certificate will be deemed to have
represented to the Trustee, the Depositor and the transferee of such Certificate
the information set forth on Exhibit E-1 upon or prior to such transfer and (b)
each prospective transferee of such Certificate will be deemed to have
represented to the Trustee, the Depositor and the transferor of such Certificate
the information set forth on Exhibit E-2 hereto.

                  An Institutional Accredited Investor (other than a QIB) may
not hold an interest in a Class H Certificate in book-entry form and must hold
such interest in a Class H Certificate in definitive form. Any transfer of such
Certificates will require, among other things described herein and in the
Agreement, delivery of the certificates and/or opinions required in connection
with the transfer of a Class H Certificate held in a physical certificated form,
as set forth above.

<PAGE>

                  No service charge will be imposed for any registration of
transfer or exchange of Class H Certificates, but the Certificate Registrar may
require payment of a sum sufficient to cover any tax or other governmental
charge that may be imposed in connection with any transfer or exchange of Class
H Certificates.

                  Notwithstanding the foregoing, for so long as this Certificate
is registered in the name of Cede & Co. or in such other name as is requested by
an authorized representative of DTC, transfers of interests in this Certificate
shall be made through the book-entry facilities of DTC.

                  The Depositor, the Master Servicer, the Special Servicer, the
Trustee, and the Certificate Registrar and any agent of the Depositor, the
Master Servicer, the Special Servicer, the Trustee, or the Certificate Registrar
may treat the Person in whose name this Certificate is registered as the owner
hereof for all purposes whatsoever and none of the Depositor, the Master
Servicer, the Special Servicer, the Trustee, the Certificate Registrar or any
such agent shall be affected by notice to the contrary.

                  The Trust Fund and the obligations created by the Agreement
shall terminate upon distribution (or provision for distribution) to the
Certificateholders of all amounts held by or on behalf of the Trustee and
required to be distributed to them pursuant to the Agreement following the
earlier to occur of (i) the final payment (or any advance with respect thereto)
or other liquidation of the last Mortgage Loan or REO Property remaining in the
Trust Fund, and (ii) the purchase by the Master Servicer, the Special Servicer
or the Majority Subordinate Certificateholder at a price determined as provided
in the Agreement of all Mortgage Loans and each REO Property remaining in the
Trust Fund. The Agreement permits, but does not require, the Master Servicer,
the Special Servicer or the Majority Subordinate Certificateholder to purchase
from the Trust Fund all Mortgage Loans and each REO Property remaining therein.
The exercise of such right will effect early retirement of the Class H
Certificates; however, such right to purchase is subject to the aggregate Stated
Principal Balance of the Mortgage Pool at the time of purchase being less than
1% of the aggregate Stated Principal Balance of the Mortgage Loans as of the
Closing Date specified on the face hereof.

                  The Agreement permits, with certain exceptions therein
provided, the amendment thereof and the modification of the rights and
obligations of the Depositor, the Master Servicer, the Special Servicer and the
Trustee and the rights of the Certificateholders under the Agreement at any time
by the Depositor, the Master Servicer, the Special Servicer and the Trustee with
the consent of the Holders of Certificates entitled to at least 51% of the
Voting Rights allocated to the affected Classes. Any such consent by the Holder
of this Certificate shall be conclusive and binding on such Holder and upon all
future Holders of this Certificate and of any Certificate issued upon the
transfer hereof or in exchange herefor or in lieu hereof whether or not notation
of such consent is made upon this Certificate. The Agreement also permits the
amendment thereof, in certain limited circumstances, including any amendment
necessary to maintain the status of

<PAGE>

the Trust Fund (or designated portions thereof) as consisting of three separate
REMICs and a grantor trust, without the consent of the Holders of any of the
Certificates.

                  Unless the certificate of authentication hereon has been
executed by the Certificate Registrar, by manual signature, this Certificate
shall not be entitled to any benefit under the Agreement or be valid for any
purpose.

                  The registered Holder hereof, by its acceptance hereof, agrees
that it will look solely to the Trust Fund (to the extent of its rights therein)
for distributions hereunder.

                  This Certificate shall be construed in accordance with the
internal laws of the State of New York applicable to agreements made and to be
performed in said State, and the obligations, rights and remedies of the Holder
hereof shall be determined in accordance with such laws.

                  IN WITNESS WHEREOF, the Certificate Registrar has caused this
Certificate to be duly executed.

Days prior to the related Record Date (which wiring instructions may be in the
form of a standing order applicable to all subsequent distributions), or
otherwise by check mailed to the address of such Certificateholder as it appears
in the Certificate Register. Notwithstanding the foregoing, the final
distribution on this Certificate (determined without regard to any possible
future reimbursement of any Realized Loss or Additional Trust Fund Expense
previously allocated to this Certificate) will be made in like manner, but only
upon presentation and surrender of this Certificate at the offices of the
Certificate Registrar or such other location specified in the notice to the
Holder hereof of such final distribution. Also notwithstanding the foregoing,
any distribution that may be made with respect to this Certificate in
reimbursement of any Realized Loss or Additional Trust Fund Expense previously
allocated to this Certificate, which reimbursement is to occur after the date on
which this Certificate is surrendered as contemplated by the preceding sentence,
will be made by check mailed to the address of the Holder that surrenders this
Certificate as such address last appears in the Certificate Register or to any
such other address of which the Trustee is subsequently notified in writing.

                  The Certificates are limited in right of distribution to
certain collections and recoveries respecting the Mortgage Loans, all as more
specifically set forth herein and in the Agreement. As provided in the
Agreement, withdrawals from the Certificate Account, the Distribution Account
and, if established, the REO Account may be made from time to time for purposes
other than, and, in certain cases, prior to, distributions to
Certificateholders, such purposes including the reimbursement of advances made,
or certain expenses incurred, with respect to the Mortgage Loans and the payment
of interest on such advances and expenses.

                  Interest accrued on this Certificate during an Interest
Accrual Period, plus any unpaid interest shortfall with respect to this
Certificate for any prior Distribution Date, if any, will be payable on the
related Distribution Date to the extent provided in the Agreement. The "Interest
Accrual Period" with respect to any Distribution Date and with respect to the
Class J Certificates is the calendar month preceding the month in which such
Distribution Date occurs and is assumed to consist of 30 days.

                  Any distribution to the Holder of this Certificate in
reduction of the Certificate Principal Balance hereof is binding on such Holder
and all future Holders of this Certificate and

<PAGE>

any Certificate issued upon the transfer hereof or in exchange herefor or in
lieu hereof whether or not notation of such distribution is made upon this
Certificate.

                  The Class J Certificates are issuable in fully registered form
only without coupons in minimum denominations specified in the Agreement. As
provided in the Agreement and subject to certain limitations therein set forth,
Class J Certificates are exchangeable for new Class J Certificates in authorized
denominations evidencing the same aggregate Percentage Interest, as requested by
the Holder surrendering the same.

                  As provided in the Agreement and subject to certain
limitations therein set forth, the transfer of this Certificate is registrable
in the Certificate Register upon surrender of this Certificate for registration
of transfer at the offices of the Certificate Registrar, duly endorsed by, or
accompanied by a written instrument of transfer in the form satisfactory to the
Certificate Registrar duly executed by, the Holder hereof or his attorney duly
authorized in writing, and thereupon one or more new Class J Certificates in
authorized denominations evidencing the same aggregate Percentage Interest will
be issued to the designated transferee or transferees.

                  With respect to any offer, sale, pledge or other transfer of
any Class J Certificate, no such transfer of a Class J Certificate shall be made
unless that transfer is made pursuant to an effective registration statement
under the Securities Act, and effective registration or qualification under
applicable state securities laws, or is made in a transaction which does not
require such registration or qualification. If such a transfer is to be made
without registration under the Securities Act (other than in connection with the
initial issuance thereof or the initial transfer thereof by the Depositor, the
Underwriters or their respective affiliates), then the Certificate Registrar
shall refuse to register such transfer unless it receives either: (i) a
certificate from the Certificateholder desiring to effect such transfer
substantially in the form attached as Exhibit E-1 to the Agreement, and a
certificate from such Certificateholder's prospective transferee substantially
in the form attached as either Exhibit E-2 (which relates to sales to QIBs in
reliance on Rule 144A) or Exhibit E-3 (which relates to sales to Institutional
Accredited Investors) to the Agreement; or (ii) an Opinion of Counsel
satisfactory to the Certificate Registrar to the effect that such transfer may
be made without registration under the Securities Act (which Opinion of Counsel
shall not be an expense of the Trust Fund or of the Depositor, the Master
Servicer, the Special Servicer, the Trustee or the Certificate Registrar in
their respective capacities as such), together with the written certification(s)
as to the facts surrounding such transfer from the Certificateholder desiring to
effect such transfer and/or such Certificateholder's prospective transferee on
which such Opinion of Counsel is based. None of the Depositor, the Trustee or
the Certificate Registrar is obligated to register or qualify the Class J
Certificates under the Securities Act or any other securities law or to take any
action not otherwise required under the Agreement to permit the transfer of any
Class J Certificate without registration or qualification. Any Class J
Certificateholder desiring to effect such a transfer shall, and by the
acceptance of its Class J Certificate agrees to, indemnify the Trustee, the
Certificate Registrar and the Depositor against any liability that may result if
the transfer is not so exempt or is not made in accordance with such federal and
state laws.

                  With respect to any offer, sale, pledge or other transfer of
any Class J Certificate that constitutes a Class of Book-Entry Certificates, if
such a transfer is to be made without

<PAGE>

registration under the Securities Act, such transfer will not be made unless the
prospective transferee delivers to the transferor (i) a certificate
substantially in the form of Exhibit E-2 hereto and addressed to the transferor,
upon or prior to such transfer, or (ii) an opinion of counsel to the effect that
such transferee is a QIB and that such transfer may be made without registration
under the Securities Act, together with the written certification(s) as to the
facts surrounding such transfer, from the prospective transferor desiring to
effect such transfer and/or the prospective transferee, on which such opinion of
counsel is based. In any event, (a) each prospective transferor of such Class J
Certificate will be deemed to have represented to the Trustee, the Depositor and
the transferee of such Certificate the information set forth on Exhibit E-1 upon
or prior to such transfer and (b) each prospective transferee of such
Certificate will be deemed to have represented to the Trustee, the Depositor and
the transferor of such Certificate the information set forth on Exhibit E-2
hereto.

                  An Institutional Accredited Investor (other than a QIB) may
not hold an interest in a Class J Certificate in book-entry form and must hold
such interest in a Class J Certificate in definitive form. Any transfer of such
Certificates will require, among other things described herein and in the
Agreement, delivery of the certificates and/or opinions required in connection
with the transfer of a Class J Certificate held in a physical certificated form,
as set forth above.

                  No service charge will be imposed for any registration of
transfer or exchange of Class J Certificates, but the Certificate Registrar may
require payment of a sum sufficient to cover any tax or other governmental
charge that may be imposed in connection with any transfer or exchange of Class
J Certificates.

                  Notwithstanding the foregoing, for so long as this Certificate
is registered in the name of Cede & Co. or in such other name as is requested by
an authorized representative of DTC, transfers of interests in this Certificate
shall be made through the book-entry facilities of DTC.

                  The Depositor, the Master Servicer, the Special Servicer, the
Trustee, and the Certificate Registrar and any agent of the Depositor, the
Master Servicer, the Special Servicer, the Trustee, or the Certificate Registrar
may treat the Person in whose name this Certificate is registered as the owner
hereof for all purposes whatsoever and none of the Depositor, the Master
Servicer, the Special Servicer, the Trustee, the Certificate Registrar or any
such agent shall be affected by notice to the contrary.

                  The Trust Fund and the obligations created by the Agreement
shall terminate upon distribution (or provision for distribution) to the
Certificateholders of all amounts held by or on behalf of the Trustee and
required to be distributed to them pursuant to the Agreement following the
earlier to occur of (i) the final payment (or any advance with respect thereto)
or other liquidation of the last Mortgage Loan or REO Property remaining in the
Trust Fund, and (ii) the purchase by the Master Servicer, the Special Servicer
or the Majority Subordinate Certificateholder at a price determined as provided
in the Agreement of all Mortgage Loans and each REO Property remaining in the
Trust Fund. The Agreement permits, but does not require, the Master Servicer,
the Special Servicer or the Majority Subordinate Certificateholder to

<PAGE>

purchase from the Trust Fund all Mortgage Loans and each REO Property remaining
therein. The exercise of such right will effect early retirement of the Class J
Certificates; however, such right to purchase is subject to the aggregate Stated
Principal Balance of the Mortgage Pool at the time of purchase being less than
1% of the aggregate Stated Principal Balance of the Mortgage Loans as of the
Closing Date specified on the face hereof.

                  The Agreement permits, with certain exceptions therein
provided, the amendment thereof and the modification of the rights and
obligations of the Depositor, the Master Servicer, the Special Servicer and the
Trustee and the rights of the Certificateholders under the Agreement at any time
by the Depositor, the Master Servicer, the Special Servicer and the Trustee with
the consent of the Holders of Certificates entitled to at least 51% of the
Voting Rights allocated to the affected Classes. Any such consent by the Holder
of this Certificate shall be conclusive and binding on such Holder and upon all
future Holders of this Certificate and of any Certificate issued upon the
transfer hereof or in exchange herefor or in lieu hereof whether or not notation
of such consent is made upon this Certificate. The Agreement also permits the
amendment thereof, in certain limited circumstances, including any amendment
necessary to maintain the status of the Trust Fund (or designated portions
thereof) as consisting of three separate REMICs and a grantor trust, without the
consent of the Holders of any of the Certificates.

                  Unless the certificate of authentication hereon has been
executed by the Certificate Registrar, by manual signature, this Certificate
shall not be entitled to any benefit under the Agreement or be valid for any
purpose.

                  The registered Holder hereof, by its acceptance hereof, agrees
that it will look solely to the Trust Fund (to the extent of its rights therein)
for distributions hereunder.

                  This Certificate shall be construed in accordance with the
internal laws of the State of New York applicable to agreements made and to be
performed in said State, and the obligations, rights and remedies of the Holder
hereof shall be determined in accordance with such laws.

                  IN WITNESS WHEREOF, the Certificate Registrar has caused this
Certificate to be duly executed.

<PAGE>

                  Pursuant to the terms of the Agreement, distributions will be
made on the 12th day of any given month, or if the 12th day is not a Business
Day, on the next succeeding Business Day (each, a "Distribution Date"). With
respect to each Distribution Date, the Determination Date is the 4th Business
Day prior to the Distribution Date (each, a "Determination Date"). Distributions
will be made commencing on the first Distribution Date specified above, to the
Person in whose name this Certificate is registered at the close of business on
the last Business Day of the month immediately preceding the month of such
distribution (the "Record Date"), in an amount equal to the product of the
Percentage Interest evidenced by this Certificate and the amount required to be
distributed to the Holders of the Class K Certificates on the applicable
Distribution Date pursuant to the Agreement. All distributions made under the
Agreement on the Class K Certificates will be made by the Trustee, by wire
transfer of immediately available funds to the account of the Person entitled
thereto at a bank or other entity having appropriate facilities therefor, if
such Certificateholder shall have provided the Trustee with wiring instructions
no less than five Business Days prior to the related Record Date (which wiring
instructions may be in the form of a standing order applicable to all subsequent
distributions), or otherwise by check mailed to the address of such
Certificateholder as it appears in the Certificate Register. Notwithstanding the
foregoing, the final distribution on this Certificate (determined without regard
to any possible future reimbursement of any Realized Loss or Additional Trust
Fund Expense previously allocated to this Certificate) will be made in like
manner, but only upon presentation and surrender of this Certificate at the
offices of the Certificate Registrar or such other location specified in the
notice to the Holder hereof of such final distribution. Also notwithstanding the
foregoing, any distribution that may be made with respect to this Certificate in
reimbursement of any Realized Loss or Additional Trust Fund Expense previously
allocated to this Certificate, which reimbursement is to occur after the date on
which this Certificate is surrendered as contemplated by the preceding sentence,
will be made by check mailed to the address of the Holder that surrenders this
Certificate as such address last appears in the Certificate Register or to any
such other address of which the Trustee is subsequently notified in writing.

                  The Certificates are limited in right of distribution to
certain collections and recoveries respecting the Mortgage Loans, all as more
specifically set forth herein and in the Agreement. As provided in the
Agreement, withdrawals from the Certificate Account, the Distribution Account
and, if established, the REO Account may be made from time to time for purposes
other than, and, in certain cases, prior to, distributions to
Certificateholders, such purposes including the reimbursement of advances made,
or certain expenses incurred, with respect to the Mortgage Loans and the payment
of interest on such advances and expenses.

                  Interest accrued on this Certificate during an Interest
Accrual Period, plus any unpaid interest shortfall with respect to this
Certificate for any prior Distribution Date, if any, will be payable on the
related Distribution Date to the extent provided in the Agreement. The "Interest
Accrual Period" with respect to any Distribution Date and with respect to the
Class K Certificates is the calendar month preceding the month in which such
Distribution Date occurs and is assumed to consist of 30 days.

<PAGE>

                  Any distribution to the Holder of this Certificate in
reduction of the Certificate Principal Balance hereof is binding on such Holder
and all future Holders of this Certificate and any Certificate issued upon the
transfer hereof or in exchange herefor or in lieu hereof whether or not notation
of such distribution is made upon this Certificate.

                  The Class K Certificates are issuable in fully registered form
only without coupons in minimum denominations specified in the Agreement. As
provided in the Agreement and subject to certain limitations therein set forth,
Class K Certificates are exchangeable for new Class K Certificates in authorized
denominations evidencing the same aggregate Percentage Interest, as requested by
the Holder surrendering the same.

                  As provided in the Agreement and subject to certain
limitations therein set forth, the transfer of this Certificate is registrable
in the Certificate Register upon surrender of this Certificate for registration
of transfer at the offices of the Certificate Registrar, duly endorsed by, or
accompanied by a written instrument of transfer in the form satisfactory to the
Certificate Registrar duly executed by, the Holder hereof or his attorney duly
authorized in writing, and thereupon one or more new Class K Certificates in
authorized denominations evidencing the same aggregate Percentage Interest will
be issued to the designated transferee or transferees.

                  With respect to any offer, sale, pledge or other transfer of
any Class K Certificate, no such transfer of a Class K Certificate shall be made
unless that transfer is made pursuant to an effective registration statement
under the Securities Act, and effective registration or qualification under
applicable state securities laws, or is made in a transaction which does not
require such registration or qualification. If such a transfer is to be made
without registration under the Securities Act (other than in connection with the
initial issuance thereof or the initial transfer thereof by the Depositor, the
Underwriters or their respective affiliates), then the Certificate Registrar
shall refuse to register such transfer unless it receives either: (i) a
certificate from the Certificateholder desiring to effect such transfer
substantially in the form attached as Exhibit E-1 to the Agreement, and a
certificate from such Certificateholder's prospective transferee substantially
in the form attached as either Exhibit E-2 (which relates to sales to QIBs in
reliance on Rule 144A) or Exhibit E-3 (which relates to sales to Institutional
Accredited Investors) to the Agreement; or (ii) an Opinion of Counsel
satisfactory to the Certificate Registrar to the effect that such transfer may
be made without registration under the Securities Act (which Opinion of Counsel
shall not be an expense of the Trust Fund or of the Depositor, the Master
Servicer, the Special Servicer, the Trustee or the Certificate Registrar in
their respective capacities as such), together with the written certification(s)
as to the facts surrounding such transfer from the Certificateholder desiring to
effect such transfer and/or such Certificateholder's prospective transferee on
which such Opinion of Counsel is based. None of the Depositor, the Trustee or
the Certificate Registrar is obligated to register or qualify the Class K
Certificates under the Securities Act or any other securities law or to take any
action not otherwise required under the Agreement to permit the transfer of any
Class K Certificate without registration or qualification. Any Class K
Certificateholder desiring to effect such a transfer shall, and by the
acceptance of its Class K Certificate agrees to, indemnify the Trustee, the
Certificate Registrar and the Depositor against any liability that may result if
the transfer is not so exempt or is not made in accordance with such federal and
state laws.

<PAGE>

                  With respect to any offer, sale, pledge or other transfer of
any Class K Certificate that constitutes a Class of Book-Entry Certificates, if
such a transfer is to be made without registration under the Securities Act,
such transfer will not be made unless the prospective transferee delivers to the
transferor (i) a certificate substantially in the form of Exhibit E-2 hereto and
addressed to the transferor, upon or prior to such transfer, or (ii) an opinion
of counsel to the effect that such transferee is a QIB and that such transfer
may be made without registration under the Securities Act, together with the
written certification(s) as to the facts surrounding such transfer, from the
prospective transferor desiring to effect such transfer and/or the prospective
transferee, on which such opinion of counsel is based. In any event, (a) each
prospective transferor of such Class K Certificate will be deemed to have
represented to the Trustee, the Depositor and the transferee of such Certificate
the information set forth on Exhibit E-1 upon or prior to such transfer and (b)
each prospective transferee of such Certificate will be deemed to have
represented to the Trustee, the Depositor and the transferor of such Certificate
the information set forth on Exhibit E-2 hereto.

                  An Institutional Accredited Investor (other than a QIB) may
not hold an interest in a Class K Certificate in book-entry form and must hold
such interest in a Class K Certificate in definitive form. Any transfer of such
Certificates will require, among other things described herein and in the
Agreement, delivery of the certificates and/or opinions required in connection
with the transfer of a Class K Certificate held in a physical certificated form,
as set forth above.

                  No service charge will be imposed for any registration of
transfer or exchange of Class K Certificates, but the Certificate Registrar may
require payment of a sum sufficient to cover any tax or other governmental
charge that may be imposed in connection with any transfer or exchange of Class
K Certificates.

                  Notwithstanding the foregoing, for so long as this Certificate
is registered in the name of Cede & Co. or in such other name as is requested by
an authorized representative of DTC, transfers of interests in this Certificate
shall be made through the book-entry facilities of DTC.

                  The Depositor, the Master Servicer, the Special Servicer, the
Trustee, and the Certificate Registrar and any agent of the Depositor, the
Master Servicer, the Special Servicer, the Trustee, or the Certificate Registrar
may treat the Person in whose name this Certificate is registered as the owner
hereof for all purposes whatsoever and none of the Depositor, the Master
Servicer, the Special Servicer, the Trustee, the Certificate Registrar or any
such agent shall be affected by notice to the contrary.

                  The Trust Fund and the obligations created by the Agreement
shall terminate upon distribution (or provision for distribution) to the
Certificateholders of all amounts held by or on behalf of the Trustee and
required to be distributed to them pursuant to the Agreement following the
earlier to occur of (i) the final payment (or any advance with respect thereto)
or other liquidation of the last Mortgage Loan or REO Property remaining in the
Trust Fund, and (ii) the purchase by the Master Servicer, the Special Servicer
or the Majority Subordinate

<PAGE>

Certificateholder at a price determined as provided in the Agreement of all
Mortgage Loans and each REO Property remaining in the Trust Fund. The Agreement
permits, but does not require, the Master Servicer, the Special Servicer or the
Majority Subordinate Certificateholder to purchase from the Trust Fund all
Mortgage Loans and each REO Property remaining therein. The exercise of such
right will effect early retirement of the Class K Certificates; however, such
right to purchase is subject to the aggregate Stated Principal Balance of the
Mortgage Pool at the time of purchase being less than 1% of the aggregate Stated
Principal Balance of the Mortgage Loans as of the Closing Date specified on the
face hereof.

                  The Agreement permits, with certain exceptions therein
provided, the amendment thereof and the modification of the rights and
obligations of the Depositor, the Master Servicer, the Special Servicer and the
Trustee and the rights of the Certificateholders under the Agreement at any time
by the Depositor, the Master Servicer, the Special Servicer and the Trustee with
the consent of the Holders of Certificates entitled to at least 51% of the
Voting Rights allocated to the affected Classes. Any such consent by the Holder
of this Certificate shall be conclusive and binding on such Holder and upon all
future Holders of this Certificate and of any Certificate issued upon the
transfer hereof or in exchange herefor or in lieu hereof whether or not notation
of such consent is made upon this Certificate. The Agreement also permits the
amendment thereof, in certain limited circumstances, including any amendment
necessary to maintain the status of the Trust Fund (or designated portions
thereof) as consisting of three separate REMICs and a grantor trust, without the
consent of the Holders of any of the Certificates.

                  Unless the certificate of authentication hereon has been
executed by the Certificate Registrar, by manual signature, this Certificate
shall not be entitled to any benefit under the Agreement or be valid for any
purpose.

                  The registered Holder hereof, by its acceptance hereof, agrees
that it will look solely to the Trust Fund (to the extent of its rights therein)
for distributions hereunder.

                  This Certificate shall be construed in accordance with the
internal laws of the State of New York applicable to agreements made and to be
performed in said State, and the obligations, rights and remedies of the Holder
hereof shall be determined in accordance with such laws.

                  IN WITNESS WHEREOF, the Certificate Registrar has caused this
Certificate to be duly executed.

used herein have the respective meanings assigned in the Agreement. This
Certificate is issued under and is subject to the terms, provisions and
conditions of the Agreement, to which Agreement the Holder of this Certificate
by virtue of the acceptance hereof assents and by which such Holder is bound.

<PAGE>

                  Pursuant to the terms of the Agreement, distributions will be
made on the 12th day of any given month, or if the 12th day is not a Business
Day, on the next succeeding Business Day (each, a "Distribution Date"). With
respect to each Distribution Date, the Determination Date is the 4th Business
Day prior to the Distribution Date (each, a "Determination Date"). Distributions
will be made commencing on the first Distribution Date specified above, to the
Person in whose name this Certificate is registered at the close of business on
the last Business Day of the month immediately preceding the month of such
distribution (the "Record Date"), in an amount equal to the product of the
Percentage Interest evidenced by this Certificate and the amount required to be
distributed to the Holders of the Class L Certificates on the applicable
Distribution Date pursuant to the Agreement. All distributions made under the
Agreement on the Class L Certificates will be made by the Trustee, by wire
transfer of immediately available funds to the account of the Person entitled
thereto at a bank or other entity having appropriate facilities therefor, if
such Certificateholder shall have provided the Trustee with wiring instructions
no less than five Business Days prior to the related Record Date (which wiring
instructions may be in the form of a standing order applicable to all subsequent
distributions), or otherwise by check mailed to the address of such
Certificateholder as it appears in the Certificate Register. Notwithstanding the
foregoing, the final distribution on this Certificate (determined without regard
to any possible future reimbursement of any Realized Loss or Additional Trust
Fund Expense previously allocated to this Certificate) will be made in like
manner, but only upon presentation and surrender of this Certificate at the
offices of the Certificate Registrar or such other location specified in the
notice to the Holder hereof of such final distribution. Also notwithstanding the
foregoing, any distribution that may be made with respect to this Certificate in
reimbursement of any Realized Loss or Additional Trust Fund Expense previously
allocated to this Certificate, which reimbursement is to occur after the date on
which this Certificate is surrendered as contemplated by the preceding sentence,
will be made by check mailed to the address of the Holder that surrenders this
Certificate as such address last appears in the Certificate Register or to any
such other address of which the Trustee is subsequently notified in writing.

                  The Certificates are limited in right of distribution to
certain collections and recoveries respecting the Mortgage Loans, all as more
specifically set forth herein and in the Agreement. As provided in the
Agreement, withdrawals from the Certificate Account, the Distribution Account
and, if established, the REO Account may be made from time to time for purposes
other than, and, in certain cases, prior to, distributions to
Certificateholders, such purposes including the reimbursement of advances made,
or certain expenses incurred, with respect to the Mortgage Loans and the payment
of interest on such advances and expenses.

                  Interest accrued on this Certificate during an Interest
Accrual Period, plus any unpaid interest shortfall with respect to this
Certificate for any prior Distribution Date, if any, will be payable on the
related Distribution Date to the extent provided in the Agreement. The "Interest
Accrual Period" with respect to any Distribution Date and with respect to the
Class L Certificates is the calendar month preceding the month in which such
Distribution Date occurs and is assumed to consist of 30 days.

<PAGE>

                  Any distribution to the Holder of this Certificate in
reduction of the Certificate Principal Balance hereof is binding on such Holder
and all future Holders of this Certificate and any Certificate issued upon the
transfer hereof or in exchange herefor or in lieu hereof whether or not notation
of such distribution is made upon this Certificate.

                  The Class L Certificates are issuable in fully registered form
only without coupons in minimum denominations specified in the Agreement. As
provided in the Agreement and subject to certain limitations therein set forth,
Class L Certificates are exchangeable for new Class L Certificates in authorized
denominations evidencing the same aggregate Percentage Interest, as requested by
the Holder surrendering the same.

                  As provided in the Agreement and subject to certain
limitations therein set forth, the transfer of this Certificate is registrable
in the Certificate Register upon surrender of this Certificate for registration
of transfer at the offices of the Certificate Registrar, duly endorsed by, or
accompanied by a written instrument of transfer in the form satisfactory to the
Certificate Registrar duly executed by, the Holder hereof or his attorney duly
authorized in writing, and thereupon one or more new Class L Certificates in
authorized denominations evidencing the same aggregate Percentage Interest will
be issued to the designated transferee or transferees.

                  With respect to any offer, sale, pledge or other transfer of
any Class L Certificate, no such transfer of a Class L Certificate shall be made
unless that transfer is made pursuant to an effective registration statement
under the Securities Act, and effective registration or qualification under
applicable state securities laws, or is made in a transaction which does not
require such registration or qualification. If such a transfer is to be made
without registration under the Securities Act (other than in connection with the
initial issuance thereof or the initial transfer thereof by the Depositor, the
Underwriters or their respective affiliates), then the Certificate Registrar
shall refuse to register such transfer unless it receives either: (i) a
certificate from the Certificateholder desiring to effect such transfer
substantially in the form attached as Exhibit E-1 to the Agreement, and a
certificate from such Certificateholder's prospective transferee substantially
in the form attached as either Exhibit E-2 (which relates to sales to QIBs in
reliance on Rule 144A) or Exhibit E-3 (which relates to sales to Institutional
Accredited Investors) to the Agreement; or (ii) an Opinion of Counsel
satisfactory to the Certificate Registrar to the effect that such transfer may
be made without registration under the Securities Act (which Opinion of Counsel
shall not be an expense of the Trust Fund or of the Depositor, the Master
Servicer, the Special Servicer, the Trustee or the Certificate Registrar in
their respective capacities as such), together with the written certification(s)
as to the facts surrounding such transfer from the Certificateholder desiring to
effect such transfer and/or such Certificateholder's prospective transferee on
which such Opinion of Counsel is based. None of the Depositor, the Trustee or
the Certificate Registrar is obligated to register or qualify the Class L
Certificates under the Securities Act or any other securities law or to take any
action not otherwise required under the Agreement to permit the transfer of any
Class L Certificate without registration or qualification. Any Class L
Certificateholder desiring to effect such a transfer shall, and by the
acceptance of its Class L Certificate agrees to, indemnify the Trustee, the
Certificate Registrar and the Depositor against any liability that may result if
the transfer is not so exempt or is not made in accordance with such federal and
state laws.

<PAGE>

                  With respect to any offer, sale, pledge or other transfer of
any Class L Certificate that constitutes a Class of Book-Entry Certificates, if
such a transfer is to be made without registration under the Securities Act,
such transfer will not be made unless the prospective transferee delivers to the
transferor (i) a certificate substantially in the form of Exhibit E-2 hereto and
addressed to the transferor, upon or prior to such transfer, or (ii) an opinion
of counsel to the effect that such transferee is a QIB and that such transfer
may be made without registration under the Securities Act, together with the
written certification(s) as to the facts surrounding such transfer, from the
prospective transferor desiring to effect such transfer and/or the prospective
transferee, on which such opinion of counsel is based. In any event, (a) each
prospective transferor of such Class L Certificate will be deemed to have
represented to the Trustee, the Depositor and the transferee of such Certificate
the information set forth on Exhibit E-1 upon or prior to such transfer and (b)
each prospective transferee of such Certificate will be deemed to have
represented to the Trustee, the Depositor and the transferor of such Certificate
the information set forth on Exhibit E-2 hereto.

                  An Institutional Accredited Investor (other than a QIB) may
not hold an interest in a Class L Certificate in book-entry form and must hold
such interest in a Class L Certificate in definitive form. Any transfer of such
Certificates will require, among other things described herein and in the
Agreement, delivery of the certificates and/or opinions required in connection
with the transfer of a Class L Certificate held in a physical certificated form,
as set forth above.

                  No service charge will be imposed for any registration of
transfer or exchange of Class L Certificates, but the Certificate Registrar may
require payment of a sum sufficient to cover any tax or other governmental
charge that may be imposed in connection with any transfer or exchange of Class
L Certificates.

                  Notwithstanding the foregoing, for so long as this Certificate
is registered in the name of Cede & Co. or in such other name as is requested by
an authorized representative of DTC, transfers of interests in this Certificate
shall be made through the book-entry facilities of DTC.

                  The Depositor, the Master Servicer, the Special Servicer, the
Trustee, and the Certificate Registrar and any agent of the Depositor, the
Master Servicer, the Special Servicer, the Trustee, or the Certificate Registrar
may treat the Person in whose name this Certificate is registered as the owner
hereof for all purposes whatsoever and none of the Depositor, the Master
Servicer, the Special Servicer, the Trustee, the Certificate Registrar or any
such agent shall be affected by notice to the contrary.

                  The Trust Fund and the obligations created by the Agreement
shall terminate upon distribution (or provision for distribution) to the
Certificateholders of all amounts held by or on behalf of the Trustee and
required to be distributed to them pursuant to the Agreement following the
earlier to occur of (i) the final payment (or any advance with respect thereto)
or other liquidation of the last Mortgage Loan or REO Property remaining in the
Trust Fund, and (ii) the purchase by the Master Servicer, the Special Servicer
or the Majority Subordinate

<PAGE>

Certificateholder at a price determined as provided in the Agreement of all
Mortgage Loans and each REO Property remaining in the Trust Fund. The Agreement
permits, but does not require, the Master Servicer, the Special Servicer or the
Majority Subordinate Certificateholder to purchase from the Trust Fund all
Mortgage Loans and each REO Property remaining therein. The exercise of such
right will effect early retirement of the Class L Certificates; however, such
right to purchase is subject to the aggregate Stated Principal Balance of the
Mortgage Pool at the time of purchase being less than 1% of the aggregate Stated
Principal Balance of the Mortgage Loans as of the Closing Date specified on the
face hereof.

                  The Agreement permits, with certain exceptions therein
provided, the amendment thereof and the modification of the rights and
obligations of the Depositor, the Master Servicer, the Special Servicer and the
Trustee and the rights of the Certificateholders under the Agreement at any time
by the Depositor, the Master Servicer, the Special Servicer and the Trustee with
the consent of the Holders of Certificates entitled to at least 51% of the
Voting Rights allocated to the affected Classes. Any such consent by the Holder
of this Certificate shall be conclusive and binding on such Holder and upon all
future Holders of this Certificate and of any Certificate issued upon the
transfer hereof or in exchange herefor or in lieu hereof whether or not notation
of such consent is made upon this Certificate. The Agreement also permits the
amendment thereof, in certain limited circumstances, including any amendment
necessary to maintain the status of the Trust Fund (or designated portions
thereof) as consisting of three separate REMICs and a grantor trust, without the

<PAGE>

                  Pursuant to the terms of the Agreement, distributions will be
made on the 12th day of any given month, or if the 12th day is not a Business
Day, on the next succeeding Business Day (each, a "Distribution Date"). With
respect to each Distribution Date, the Determination Date is the 4th Business

will be made commencing on the first Distribution Date specified above, to the
Person in whose name this Certificate is registered at the close of business on
the last Business Day of the month immediately preceding the month of such
distribution (the "Record Date"), in an amount equal to the product of the
Percentage Interest evidenced by this Certificate and the amount required to be
distributed to the Holders of the Class M Certificates on the applicable
Distribution Date pursuant to the Agreement. All distributions made under the
Agreement on the Class M Certificates will be made by the Trustee, by wire

Certificateholder as it appears in the Certificate Register. Notwithstanding the
foregoing, the final distribution on this Certificate (determined without regard
to any possible future reimbursement of any Realized Loss or Additional Trust
Fund Expense previously allocated to this Certificate) will be made in like
manner, but only upon presentation and surrender of this Certificate at the
offices of the Certificate Registrar or such other location specified in the
notice to the Holder hereof of such final distribution. Also notwithstanding the
foregoing, any distribution that may be made with respect to this Certificate in
reimbursement of any Realized Loss or Additional Trust Fund Expense previously
allocated to this Certificate, which reimbursement is to occur after the date on
which this Certificate is surrendered as contemplated by the preceding sentence,
will be made by check mailed to the address of the Holder that surrenders this
Certificate as such address last appears in the Certificate Register or to any
such other address of which the Trustee is subsequently notified in writing.

                  The Certificates are limited in right of distribution to
certain collections and recoveries respecting the Mortgage Loans, all as more
specifically set forth herein and in the Agreement. As provided in the
Agreement, withdrawals from the Certificate Account, the Distribution Account
and, if established, the REO Account may be made from time to time for purposes
other than, and, in certain cases, prior to, distributions to
Certificateholders, such purposes including the reimbursement of advances made,
or certain expenses incurred, with respect to the Mortgage Loans and the payment
of interest on such advances and expenses.

                  Interest accrued on this Certificate during an Interest
Accrual Period, plus any unpaid interest shortfall with respect to this
Certificate for any prior Distribution Date, if any, will be payable on the
related Distribution Date to the extent provided in the Agreement. The "Interest
Accrual Period" with respect to any Distribution Date and with respect to the
Class M Certificates is the calendar month preceding the month in which such
Distribution Date occurs and is assumed to consist of 30 days.

<PAGE>

                  Any distribution to the Holder of this Certificate in
reduction of the Certificate Principal Balance hereof is binding on such Holder
and all future Holders of this Certificate and any Certificate issued upon the
transfer hereof or in exchange herefor or in lieu hereof whether or not notation
of such distribution is made upon this Certificate.

                  The Class M Certificates are issuable in fully registered form
only without coupons in minimum denominations specified in the Agreement. As
provided in the Agreement and subject to certain limitations therein set forth,
Class M Certificates are exchangeable for new Class M Certificates in authorized
denominations evidencing the same aggregate Percentage Interest, as requested by
the Holder surrendering the same.

                  As provided in the Agreement and subject to certain
limitations therein set forth, the transfer of this Certificate is registrable
in the Certificate Register upon surrender of this Certificate for registration
of transfer at the offices of the Certificate Registrar, duly endorsed by, or
accompanied by a written instrument of transfer in the form satisfactory to the
Certificate Registrar duly executed by, the Holder hereof or his attorney duly
authorized in writing, and thereupon one or more new Class M Certificates in
authorized denominations evidencing the same aggregate Percentage Interest will
be issued to the designated transferee or transferees.

                  With respect to any offer, sale, pledge or other transfer of
any Class M Certificate, no such transfer of a Class M Certificate shall be made
unless that transfer is made pursuant to an effective registration statement
under the Securities Act, and effective registration or qualification under
applicable state securities laws, or is made in a transaction which does not
require such registration or qualification. If such a transfer is to be made
without registration under the Securities Act (other than in connection with the
initial issuance thereof or the initial transfer thereof by the Depositor, the
Underwriters or their respective affiliates), then the Certificate Registrar
shall refuse to register such transfer unless it receives either: (i) a
certificate from the Certificateholder desiring to effect such transfer
substantially in the form attached as Exhibit E-1 to the Agreement, and a
certificate from such Certificateholder's prospective transferee substantially
in the form attached as either Exhibit E-2 (which relates to sales to QIBs in
reliance on Rule 144A) or Exhibit E-3 (which relates to sales to Institutional
Accredited Investors) to the Agreement; or (ii) an Opinion of Counsel
satisfactory to the Certificate Registrar to the effect that such transfer may
be made without registration under the Securities Act (which Opinion of Counsel
shall not be an expense of the Trust Fund or of the Depositor, the Master
Servicer, the Special Servicer, the Trustee or the Certificate Registrar in
their respective capacities as such), together with the written certification(s)
as to the facts surrounding such transfer from the Certificateholder desiring to
effect such transfer and/or such Certificateholder's prospective transferee on
which such Opinion of Counsel is based. None of the Depositor, the Trustee or
the Certificate Registrar is obligated to register or qualify the Class M
Certificates under the Securities Act or any other securities law or to take any
action not otherwise required under the Agreement to permit the transfer of any
Class M Certificate without registration or qualification. Any Class M
Certificateholder desiring to effect such a transfer shall, and by the
acceptance of its Class M Certificate agrees to, indemnify the Trustee, the
Certificate Registrar and the Depositor against any liability that may result if
the transfer is not so exempt or is not made in accordance with such federal and
state laws.

<PAGE>

                  With respect to any offer, sale, pledge or other transfer of
any Class M Certificate that constitutes a Class of Book-Entry Certificates, if
such a transfer is to be made without registration under the Securities Act,
such transfer will not be made unless the prospective transferee delivers to the
transferor (i) a certificate substantially in the form of Exhibit E-2 hereto and
addressed to the transferor, upon or prior to such transfer, or (ii) an opinion
of counsel to the effect that such transferee is a QIB and that such transfer
may be made without registration under the Securities Act, together with the
written certification(s) as to the facts surrounding such transfer, from the
prospective transferor desiring to effect such transfer and/or the prospective
transferee, on which such opinion of counsel is based. In any event, (a) each
prospective transferor of such Class M Certificate will be deemed to have
represented to the Trustee, the Depositor and the transferee of such Certificate
the information set forth on Exhibit E-1 upon or prior to such transfer and (b)
each prospective transferee of such Certificate will be deemed to have
represented to the Trustee, the Depositor and the transferor of such Certificate
the information set forth on Exhibit E-2 hereto.

                  An Institutional Accredited Investor (other than a QIB) may
not hold an interest in a Class M Certificate in book-entry form and must hold
such interest in a Class M Certificate in definitive form. Any transfer of such
Certificates will require, among other things described herein and in the
Agreement, delivery of the certificates and/or opinions required in connection
with the transfer of a Class M Certificate held in a physical certificated form,
as set forth above.

                  No service charge will be imposed for any registration of
transfer or exchange of Class M Certificates, but the Certificate Registrar may
require payment of a sum sufficient to cover any tax or other governmental
charge that may be imposed in connection with any transfer or exchange of Class
M Certificates.

                  Notwithstanding the foregoing, for so long as this Certificate
is registered in the name of Cede & Co. or in such other name as is requested by
an authorized representative of DTC, transfers of interests in this Certificate
shall be made through the book-entry facilities of DTC.

                  The Depositor, the Master Servicer, the Special Servicer, the
Trustee, and the Certificate Registrar and any agent of the Depositor, the
Master Servicer, the Special Servicer, the Trustee, or the Certificate Registrar
may treat the Person in whose name this Certificate is registered as the owner
hereof for all purposes whatsoever and none of the Depositor, the Master
Servicer, the Special Servicer, the Trustee, the Certificate Registrar or any
such agent shall be affected by notice to the contrary.

                  The Trust Fund and the obligations created by the Agreement
shall terminate upon distribution (or provision for distribution) to the
Certificateholders of all amounts held by or on behalf of the Trustee and
required to be distributed to them pursuant to the Agreement following the
earlier to occur of (i) the final payment (or any advance with respect thereto)
or other liquidation of the last Mortgage Loan or REO Property remaining in the
Trust Fund, and (ii) the purchase by the Master Servicer, the Special Servicer
or the Majority Subordinate Certificateholder at a price determined as provided
in the Agreement of all Mortgage Loans and

<PAGE>

each REO Property remaining in the Trust Fund. The Agreement permits, but does
not require, the Master Servicer, the Special Servicer or the Majority
Subordinate Certificateholder to purchase from the Trust Fund all Mortgage Loans
and each REO Property remaining therein. The exercise of such right will effect
early retirement of the Class M Certificates; however, such right to purchase is
subject to the aggregate Stated Principal Balance of the Mortgage Pool at the
time of purchase being less than 1% of the aggregate Stated Principal Balance of
the Mortgage Loans as of the Closing Date specified on the face hereof.

                  The Agreement permits, with certain exceptions therein
provided, the amendment thereof and the modification of the rights and
obligations of the Depositor, the Master Servicer, the Special Servicer and the
Trustee and the rights of the Certificateholders under the Agreement at any time
by the Depositor, the Master Servicer, the Special Servicer and the Trustee with
the consent of the Holders of Certificates entitled to at least 51% of the
Voting Rights allocated to the affected Classes. Any such consent by the Holder
of this Certificate shall be conclusive and binding on such Holder and upon all
future Holders of this Certificate and of any Certificate issued upon the
transfer hereof or in exchange herefor or in lieu hereof whether or not notation
of such consent is made upon this Certificate. The Agreement also permits the
amendment thereof, in certain limited circumstances, including any amendment
necessary to maintain the status of the Trust Fund (or designated portions
thereof) as consisting of three separate REMICs and a grantor trust, without the
consent of the Holders of any of the Certificates.

                  Unless the certificate of authentication hereon has been
executed by the Certificate Registrar, by manual signature, this Certificate
shall not be entitled to any benefit under the Agreement or be valid for any
purpose.

                  The registered Holder hereof, by its acceptance hereof, agrees
that it will look solely to the Trust Fund (to the extent of its rights therein)
for distributions hereunder.

                  This Certificate shall be construed in accordance with the
internal laws of the State of New York applicable to agreements made and to be
performed in said State, and the obligations, rights and remedies of the Holder
hereof shall be determined in accordance with such laws.

Certificate to be duly executed.

used herein have the respective meanings assigned in the Agreement. This
Certificate is issued under and is subject to the terms, provisions and
conditions of the Agreement, to which Agreement the Holder of this Certificate
by virtue of the acceptance hereof assents and by which such Holder is bound.

<PAGE>

                  Pursuant to the terms of the Agreement, distributions will be
made on the 12th day of any given month, or if the 12th day is not a Business
Day, on the next succeeding Business Day (each, a "Distribution Date"). With
respect to each Distribution Date, the Determination Date is the 4th Business
Day prior to the Distribution Date (each, a "Determination Date"). Distributions
will be made commencing on the first Distribution Date specified above, to the
Person in whose name this Certificate is registered at the close of business on
the last Business Day of the month immediately preceding the month of such
distribution (the "Record Date"), in an amount equal to the product of the
Percentage Interest evidenced by this Certificate and the amount required to be
distributed to the Holders of the Class N Certificates on the applicable
Distribution Date pursuant to the Agreement. All distributions made under the
Agreement on the Class N Certificates will be made by the Trustee, by wire
transfer of immediately available funds to the account of the Person entitled
thereto at a bank or other entity having appropriate facilities therefor, if
such Certificateholder shall have provided the Trustee with wiring instructions
no less than five Business Days prior to the related Record Date (which wiring
instructions may be in the form of a standing order applicable to all subsequent
distributions), or otherwise by check mailed to the address of such
Certificateholder as it appears in the Certificate Register. Notwithstanding the
foregoing, the final distribution on this Certificate (determined without regard
to any possible future reimbursement of any Realized Loss or Additional Trust
Fund Expense previously allocated to this Certificate) will be made in like
manner, but only upon presentation and surrender of this Certificate at the
offices of the Certificate Registrar or such other location specified in the
notice to the Holder hereof of such final distribution. Also notwithstanding the
foregoing, any distribution that may be made with respect to this Certificate in
reimbursement of any Realized Loss or Additional Trust Fund Expense previously
allocated to this Certificate, which reimbursement is to occur after the date on
which this Certificate is surrendered as contemplated by the preceding sentence,
will be made by check mailed to the address of the Holder that surrenders this
Certificate as such address last appears in the Certificate Register or to any
such other address of which the Trustee is subsequently notified in writing.

                  The Certificates are limited in right of distribution to
certain collections and recoveries respecting the Mortgage Loans, all as more
specifically set forth herein and in the Agreement. As provided in the
Agreement, withdrawals from the Certificate Account, the Distribution Account
and, if established, the REO Account may be made from time to time for purposes
other than, and, in certain cases, prior to, distributions to
Certificateholders, such purposes including the reimbursement of advances made,
or certain expenses incurred, with respect to the Mortgage Loans and the payment
of interest on such advances and expenses.

                  Interest accrued on this Certificate during an Interest
Accrual Period, plus any unpaid interest shortfall with respect to this
Certificate for any prior Distribution Date, if any, will be payable on the
related Distribution Date to the extent provided in the Agreement. The "Interest
Accrual Period" with respect to any Distribution Date and with respect to the
Class N Certificates is the calendar month preceding the month in which such
Distribution Date occurs and is assumed to consist of 30 days.

<PAGE>

                  Any distribution to the Holder of this Certificate in
reduction of the Certificate Principal Balance hereof is binding on such Holder
and all future Holders of this Certificate and any Certificate issued upon the
transfer hereof or in exchange herefor or in lieu hereof whether or not notation
of such distribution is made upon this Certificate.

                  The Class N Certificates are issuable in fully registered form
only without coupons in minimum denominations specified in the Agreement. As
provided in the Agreement and subject to certain limitations therein set forth,
Class N Certificates are exchangeable for new Class N Certificates in authorized
denominations evidencing the same aggregate Percentage Interest, as requested by
the Holder surrendering the same.

                  As provided in the Agreement and subject to certain
limitations therein set forth, the transfer of this Certificate is registrable
in the Certificate Register upon surrender of this Certificate for registration
of transfer at the offices of the Certificate Registrar, duly endorsed by, or
accompanied by a written instrument of transfer in the form satisfactory to the
Certificate Registrar duly executed by, the Holder hereof or his attorney duly
authorized in writing, and thereupon one or more new Class N Certificates in
authorized denominations evidencing the same aggregate Percentage Interest will
be issued to the designated transferee or transferees.

                  With respect to any offer, sale, pledge or other transfer of
any Class N Certificate, no such transfer of a Class N Certificate shall be made
unless that transfer is made pursuant to an effective registration statement
under the Securities Act, and effective registration or qualification under
applicable state securities laws, or is made in a transaction which does not
require such registration or qualification. If such a transfer is to be made
without registration under the Securities Act (other than in connection with the
initial issuance thereof or the initial transfer thereof by the Depositor, the
Underwriters or their respective affiliates), then the Certificate Registrar
shall refuse to register such transfer unless it receives either: (i) a
certificate from the Certificateholder desiring to effect such transfer
substantially in the form attached as Exhibit E-1 to the Agreement, and a
certificate from such Certificateholder's prospective transferee substantially
in the form attached as either Exhibit E-2 (which relates to sales to QIBs in
reliance on Rule 144A) or Exhibit E-3 (which relates to sales to Institutional
Accredited Investors) to the Agreement; or (ii) an Opinion of Counsel
satisfactory to the Certificate Registrar to the effect that such transfer may
be made without registration under the Securities Act (which Opinion of Counsel
shall not be an expense of the Trust Fund or of the Depositor, the Master
Servicer, the Special Servicer, the Trustee or the Certificate Registrar in
their respective capacities as such), together with the written certification(s)
as to the facts surrounding such transfer from the Certificateholder desiring to
effect such transfer and/or such Certificateholder's prospective transferee on
which such Opinion of Counsel is based. None of the Depositor, the Trustee or
the Certificate Registrar is obligated to register or qualify the Class N
Certificates under the Securities Act or any other securities law or to take any
action not otherwise required under the Agreement to permit the transfer of any
Class N Certificate without registration or qualification. Any Class N
Certificateholder desiring to effect such a transfer shall, and by the
acceptance of its Class N Certificate agrees to, indemnify the Trustee, the
Certificate Registrar and the Depositor against any liability that may result if
the transfer is not so exempt or is not made in accordance with such federal and
state laws.

<PAGE>

                  With respect to any offer, sale, pledge or other transfer of
any Class N Certificate that constitutes a Class of Book-Entry Certificates, if
such a transfer is to be made without registration under the Securities Act,
such transfer will not be made unless the prospective transferee delivers to the
transferor (i) a certificate substantially in the form of Exhibit E-2 hereto and
addressed to the transferor, upon or prior to such transfer, or (ii) an opinion
of counsel to the effect that such transferee is a QIB and that such transfer
may be made without registration under the Securities Act, together with the
written certification(s) as to the facts surrounding such transfer, from the
prospective transferor desiring to effect such transfer and/or the prospective
transferee, on which such opinion of counsel is based. In any event, (a) each
prospective transferor of such Class N Certificate will be deemed to have
represented to the Trustee, the Depositor and the transferee of such Certificate
the information set forth on Exhibit E-1 upon or prior to such transfer and (b)
each prospective transferee of such Certificate will be deemed to have
represented to the Trustee, the Depositor and the transferor of such Certificate
the information set forth on Exhibit E-2 hereto.

                  An Institutional Accredited Investor (other than a QIB) may
not hold an interest in a Class N Certificate in book-entry form and must hold
such interest in a Class N Certificate in definitive form. Any transfer of such
Certificates will require, among other things described herein and in the
Agreement, delivery of the certificates and/or opinions required in connection
with the transfer of a Class N Certificate held in a physical certificated form,
as set forth above.

                  No service charge will be imposed for any registration of
transfer or exchange of Class N Certificates, but the Certificate Registrar may
require payment of a sum sufficient to cover any tax or other governmental
charge that may be imposed in connection with any transfer or exchange of Class
N Certificates.

                  Notwithstanding the foregoing, for so long as this Certificate
is registered in the name of Cede & Co. or in such other name as is requested by
an authorized representative of DTC, transfers of interests in this Certificate
shall be made through the book-entry facilities of DTC.

                  The Depositor, the Master Servicer, the Special Servicer, the
Trustee, and the Certificate Registrar and any agent of the Depositor, the
Master Servicer, the Special Servicer, the Trustee or the Certificate Registrar
may treat the Person in whose name this Certificate is registered as the owner
hereof for all purposes whatsoever and none of the Depositor, the Master
Servicer, the Special Servicer, the Trustee, the Certificate Registrar or any
such agent shall be affected by notice to the contrary.

                  The Trust Fund and the obligations created by the Agreement
shall terminate upon distribution (or provision for distribution) to the
Certificateholders of all amounts held by or on behalf of the Trustee and
required to be distributed to them pursuant to the Agreement following the
earlier to occur of (i) the final payment (or any advance with respect thereto)
or other liquidation of the last Mortgage Loan or REO Property remaining in the
Trust Fund, and (ii) the purchase by the Master Servicer, the Special Servicer
or the Majority Subordinate

<PAGE>

Certificateholder at a price determined as provided in the Agreement of all
Mortgage Loans and each REO Property remaining in the Trust Fund. The Agreement
permits, but does not require, the Master Servicer, the Special Servicer or the
Majority Subordinate Certificateholder to purchase from the Trust Fund all
Mortgage Loans and each REO Property remaining therein. The exercise of such
right will effect early retirement of the Class N Certificates; however, such
right to purchase is subject to the aggregate Stated Principal Balance of the
Mortgage Pool at the time of purchase being less than 1% of the aggregate Stated
Principal Balance of the Mortgage Loans as of the Closing Date specified on the
face hereof.

                  The Agreement permits, with certain exceptions therein
provided, the amendment thereof and the modification of the rights and
obligations of the Depositor, the Master Servicer, the Special Servicer and the
Trustee and the rights of the Certificateholders under the Agreement at any time
by the Depositor, the Master Servicer, the Special Servicer and the Trustee with
the consent of the Holders of Certificates entitled to at least 51% of the
Voting Rights allocated to the affected Classes. Any such consent by the Holder
of this Certificate shall be conclusive and binding on such Holder and upon all
future Holders of this Certificate and of any Certificate issued upon the
transfer hereof or in exchange herefor or in lieu hereof whether or not notation
of such consent is made upon this Certificate. The Agreement also permits the
amendment thereof, in certain limited circumstances, including any amendment
necessary to maintain the status of the Trust Fund (or designated portions
thereof) as consisting of three separate REMICs and a grantor trust, without the
consent of the Holders of any of the Certificates.

                  Unless the certificate of authentication hereon has been
executed by the Certificate Registrar, by manual signature, this Certificate
shall not be entitled to any benefit under the Agreement or be valid for any
purpose.

                  The registered Holder hereof, by its acceptance hereof, agrees
that it will look solely to the Trust Fund (to the extent of its rights therein)
for distributions hereunder.

                  This Certificate shall be construed in accordance with the
internal laws of the State of New York applicable to agreements made and to be
performed in said State, and the obligations, rights and remedies of the Holder
hereof shall be determined in accordance with such laws.

                  IN WITNESS WHEREOF, the Certificate Registrar has caused this
Certificate to be duly executed.

                  This certifies that Cede & Co. is the registered owner of the
Percentage Interest evidenced by this Class P Certificate (obtained by dividing
the principal amount of this Class P Certificate (its "Certificate Principal
Balance") as of the Closing Date by the aggregate principal amount of all the

in that certain beneficial ownership interest evidenced by all the Class P

Agreement, dated as specified above (the "Agreement"), among Merrill Lynch

(herein called the "Master Servicer", which term includes any successor entity
under the Agreement), ARCap Servicing, Inc. (herein called the "Special
Servicer", which term includes any successor entity under the Agreement),
LaSalle Bank National Association (herein called the "Trustee", which term

is set forth hereafter. To the extent not defined herein, the capitalized terms
used herein have the respective meanings assigned in the Agreement. This
Certificate is issued under and is subject to the terms, provisions and
conditions of the Agreement, to which Agreement the Holder of this Certificate
by virtue of the acceptance hereof assents and by which such Holder is bound.

<PAGE>

                  Pursuant to the terms of the Agreement, distributions will be
made on the 12th day of any given month, or if the 12th day is not a Business
Day, on the next succeeding Business Day (each, a "Distribution Date"). With
respect to each Distribution Date, the Determination Date is the 4th Business
Day prior to the Distribution Date (each, a "Determination Date"). Distributions
will be made commencing on the first Distribution Date specified above, to the
Person in whose name this Certificate is registered at the close of business on
the last Business Day of the month immediately preceding the month of such
distribution (the "Record Date"), in an amount equal to the product of the
Percentage Interest evidenced by this Certificate and the amount required to be
distributed to the Holders of the Class P Certificates on the applicable
Distribution Date pursuant to the Agreement. All distributions made under the
Agreement on the Class P Certificates will be made by the Trustee, by wire
transfer of immediately available funds to the account of the Person entitled
thereto at a bank or other entity having appropriate facilities therefor, if
such Certificateholder shall have provided the Trustee with wiring instructions
no less than five Business Days prior to the related Record Date (which wiring
instructions may be in the form of a standing order applicable to all subsequent
distributions), or otherwise by check mailed to the address of such
Certificateholder as it appears in the Certificate Register. Notwithstanding the
foregoing, the final distribution on this Certificate (determined without regard
to any possible future reimbursement of any Realized Loss or Additional Trust
Fund Expense previously allocated to this Certificate) will be made in like
manner, but only upon presentation and surrender of this Certificate at the
offices of the Certificate Registrar or such other location specified in the
notice to the Holder hereof of such final distribution. Also notwithstanding the
foregoing, any distribution that may be made with respect to this Certificate in
reimbursement of any Realized Loss or Additional Trust Fund Expense previously
allocated to this Certificate, which reimbursement is to occur after the date on
which this Certificate is surrendered as contemplated by the preceding sentence,
will be made by check mailed to the address of the Holder that surrenders this
Certificate as such address last appears in the Certificate Register or to any
such other address of which the Trustee is subsequently notified in writing.

                  The Certificates are limited in right of distribution to
certain collections and recoveries respecting the Mortgage Loans, all as more
specifically set forth herein and in the Agreement. As provided in the
Agreement, withdrawals from the Certificate Account, the Distribution Account
and, if established, the REO Account may be made from time to time for purposes
other than, and, in certain cases, prior to, distributions to
Certificateholders, such purposes including the reimbursement of advances made,
or certain expenses incurred, with respect to the Mortgage Loans and the payment
of interest on such advances and expenses.

                  Interest accrued on this Certificate during an Interest
Accrual Period, plus any unpaid interest shortfall with respect to this
Certificate for any prior Distribution Date, if any, will be payable on the
related Distribution Date to the extent provided in the Agreement. The "Interest
Accrual Period" with respect to any Distribution Date and with respect to the
Class P Certificates is the calendar month preceding the month in which such
Distribution Date occurs and is assumed to consist of 30 days.

<PAGE>

                  Any distribution to the Holder of this Certificate in
reduction of the Certificate Principal Balance hereof is binding on such Holder
and all future Holders of this Certificate and any Certificate issued upon the
transfer hereof or in exchange herefor or in lieu hereof whether or not notation
of such distribution is made upon this Certificate.

                  The Class P Certificates are issuable in fully registered form
only without coupons in minimum denominations specified in the Agreement. As
provided in the Agreement and subject to certain limitations therein set forth,
Class P Certificates are exchangeable for new Class P Certificates in authorized
denominations evidencing the same aggregate Percentage Interest, as requested by
the Holder surrendering the same.

                  As provided in the Agreement and subject to certain
limitations therein set forth, the transfer of this Certificate is registrable
in the Certificate Register upon surrender of this Certificate for registration
of transfer at the offices of the Certificate Registrar, duly endorsed by, or
accompanied by a written instrument of transfer in the form satisfactory to the
Certificate Registrar duly executed by, the Holder hereof or his attorney duly
authorized in writing, and thereupon one or more new Class P Certificates in
authorized denominations evidencing the same aggregate Percentage Interest will
be issued to the designated transferee or transferees.

                  With respect to any offer, sale, pledge or other transfer of
any Class P Certificate, no such transfer of a Class P Certificate shall be made
unless that transfer is made pursuant to an effective registration statement
under the Securities Act, and effective registration or qualification under
applicable state securities laws, or is made in a transaction which does not
require such registration or qualification. If such a transfer is to be made
without registration under the Securities Act (other than in connection with the
initial issuance thereof or the initial transfer thereof by the Depositor, the
Underwriters or their respective affiliates), then the Certificate Registrar
shall refuse to register such transfer unless it receives either: (i) a
certificate from the Certificateholder desiring to effect such transfer
substantially in the form attached as Exhibit E-1 to the Agreement, and a
certificate from such Certificateholder's prospective transferee substantially
in the form attached as either Exhibit E-2 (which relates to sales to QIBs in
reliance on Rule 144A) or Exhibit E-3 (which relates to sales to Institutional
Accredited Investors) to the Agreement; or (ii) an Opinion of Counsel
satisfactory to the Certificate Registrar to the effect that such transfer may
be made without registration under the Securities Act (which Opinion of Counsel
shall not be an expense of the Trust Fund or of the Depositor, the Master
Servicer, the Special Servicer, the Trustee or the Certificate Registrar in
their respective capacities as such), together with the written certification(s)
as to the facts surrounding such transfer from the Certificateholder desiring to
effect such transfer and/or such Certificateholder's prospective transferee on
which such Opinion of Counsel is based. None of the Depositor, the Trustee or
the Certificate Registrar is obligated to register or qualify the Class P
Certificates under the Securities Act or any other securities law or to take any
action not otherwise required under the Agreement to permit the transfer of any
Class P Certificate without registration or qualification. Any Class P
Certificateholder desiring to effect such a transfer shall, and by the
acceptance of its Class P Certificate agrees to, indemnify the Trustee, the
Certificate Registrar and the Depositor against any liability that may result if
the transfer is not so exempt or is not made in accordance with such federal and
state laws.

<PAGE>

                  With respect to any offer, sale, pledge or other transfer of
any Class P Certificate that constitutes a Class of Book-Entry Certificates, if
such a transfer is to be made without registration under the Securities Act,
such transfer will not be made unless the prospective transferee delivers to the
transferor (i) a certificate substantially in the form of Exhibit E-2 hereto and
addressed to the transferor, upon or prior to such transfer, or (ii) an opinion
of counsel to the effect that such transferee is a QIB and that such transfer
may be made without registration under the Securities Act, together with the
written certification(s) as to the facts surrounding such transfer, from the
prospective transferor desiring to effect such transfer and/or the prospective
transferee, on which such opinion of counsel is based. In any event, (a) each
prospective transferor of such Class P Certificate will be deemed to have
represented to the Trustee, the Depositor and the transferee of such Certificate
the information set forth on Exhibit E-1 upon or prior to such transfer and (b)
each prospective transferee of such Certificate will be deemed to have
represented to the Trustee, the Depositor and the transferor of such Certificate
the information set forth on Exhibit E-2 hereto.

                  An Institutional Accredited Investor (other than a QIB) may
not hold an interest in a Class P Certificate in book-entry form and must hold
such interest in a Class P Certificate in definitive form. Any transfer of such
Certificates will require, among other things described herein and in the
Agreement, delivery of the certificates and/or opinions required in connection
with the transfer of a Class P Certificate held in a physical certificated form,
as set forth above.

                  No service charge will be imposed for any registration of
transfer or exchange of Class P Certificates, but the Certificate Registrar may
require payment of a sum sufficient to cover any tax or other governmental
charge that may be imposed in connection with any transfer or exchange of Class
P Certificates.

                  Notwithstanding the foregoing, for so long as this Certificate
is registered in the name of Cede & Co. or in such other name as is requested by
an authorized representative of DTC, transfers of interests in this Certificate
shall be made through the book-entry facilities of DTC.

                  The Depositor, the Master Servicer, the Special Servicer, the
Trustee, and the Certificate Registrar and any agent of the Depositor, the
Master Servicer, the Special Servicer, the Trustee or the Certificate Registrar
may treat the Person in whose name this Certificate is registered as the owner
hereof for all purposes whatsoever and none of the Depositor, the Master
Servicer, the Special Servicer, the Trustee, the Certificate Registrar or any
such agent shall be affected by notice to the contrary.

                  The Trust Fund and the obligations created by the Agreement
shall terminate upon distribution (or provision for distribution) to the
Certificateholders of all amounts held by or on behalf of the Trustee and
required to be distributed to them pursuant to the Agreement following the
earlier to occur of (i) the final payment (or any advance with respect thereto)
or other liquidation of the last Mortgage Loan or REO Property remaining in the
Trust Fund, and (ii) the purchase by the Master Servicer, the Special Servicer
or the Majority Subordinate Certificateholder at a price determined as provided
in the Agreement of all Mortgage Loans and

<PAGE>

each REO Property remaining in the Trust Fund. The Agreement permits, but does
not require, the Master Servicer, the Special Servicer or the Majority
Subordinate Certificateholder to purchase from the Trust Fund all Mortgage Loans
and each REO Property remaining therein. The exercise of such right will effect
early retirement of the Class P Certificates; however, such right to purchase is
subject to the aggregate Stated Principal Balance of the Mortgage Pool at the
time of purchase being less than 1% of the aggregate Stated Principal Balance of
the Mortgage Loans as of the Closing Date specified on the face hereof.

                  The Agreement permits, with certain exceptions therein
provided, the amendment thereof and the modification of the rights and
obligations of the Depositor, the Master Servicer, the Special Servicer and the
Trustee and the rights of the Certificateholders under the Agreement at any time
by the Depositor, the Master Servicer, the Special Servicer and the Trustee with
the consent of the Holders of Certificates entitled to at least 51% of the
Voting Rights allocated to the affected Classes. Any such consent by the Holder
of this Certificate shall be conclusive and binding on such Holder and upon all
future Holders of this Certificate and of any Certificate issued upon the
transfer hereof or in exchange herefor or in lieu hereof whether or not notation
of such consent is made upon this Certificate. The Agreement also permits the
amendment thereof, in certain limited circumstances, including any amendment
necessary to maintain the status of the Trust Fund (or designated portions
thereof) as consisting of three separate REMICs and a grantor trust, without the
consent of the Holders of any of the Certificates.

                  Unless the certificate of authentication hereon has been
executed by the Certificate Registrar, by manual signature, this Certificate
shall not be entitled to any benefit under the Agreement or be valid for any
purpose.

                  The registered Holder hereof, by its acceptance hereof, agrees
that it will look solely to the Trust Fund (to the extent of its rights therein)
for distributions hereunder.

                  This Certificate shall be construed in accordance with the
internal laws of the State of New York applicable to agreements made and to be
performed in said State, and the obligations, rights and remedies of the Holder
hereof shall be determined in accordance with such laws.

                  IN WITNESS WHEREOF, the Certificate Registrar has caused this
Certificate to be duly executed.

made on the 12th day of any given month, or if the 12th day is not a Business
Day, on the next succeeding Business Day (each, a "Distribution Date"). With
respect to each Distribution Date, the Determination Date is the 4th Business
Day prior to the Distribution Date (each, a "Determination Date"). Distributions
will be made commencing on the first Distribution Date specified above, to the
Person in whose name this Certificate is registered at the close of business on
the last Business Day of the month immediately preceding the month of such
distribution (the "Record Date"), in an amount equal to the product of the
Percentage Interest evidenced by this Certificate and the amount required to be
distributed to the Holders of the Class Q Certificates on the applicable
Distribution Date pursuant to the Agreement. All distributions made under the
Agreement on the Class Q Certificates will be made by the Trustee, by wire
transfer of immediately available funds to the account of the Person entitled
thereto at a bank or other entity having appropriate facilities therefor, if
such Certificateholder shall have provided the Trustee with wiring instructions
no less than five Business Days prior to the related Record Date (which wiring
instructions may be in the form of a standing order applicable to all subsequent
distributions), or otherwise by check mailed to the address of such
Certificateholder as it appears in the Certificate Register. Notwithstanding the
foregoing, the final distribution on this Certificate (determined without regard
to any possible future reimbursement of any Realized Loss or Additional Trust
Fund Expense previously allocated to this Certificate) will be made in like
manner, but only upon presentation and surrender of this Certificate at the
offices of the Certificate Registrar or such other location specified in the
notice to the Holder hereof of such final distribution. Also notwithstanding the
foregoing, any distribution that may be made with respect to this Certificate in
reimbursement of any Realized Loss or Additional Trust Fund Expense previously
allocated to this Certificate, which reimbursement is to occur after the date on
which this Certificate is surrendered as contemplated by the preceding sentence,
will be made by check mailed to the address of the Holder that surrenders this
Certificate as such address last appears in the Certificate Register or to any
such other address of which the Trustee is subsequently notified in writing.

                  The Certificates are limited in right of distribution to
certain collections and recoveries respecting the Mortgage Loans, all as more
specifically set forth herein and in the Agreement. As provided in the
Agreement, withdrawals from the Certificate Account, the Distribution Account
and, if established, the REO Account may be made from time to time for purposes
other than, and, in certain cases, prior to, distributions to
Certificateholders, such purposes including the reimbursement of advances made,
or certain expenses incurred, with respect to the Mortgage Loans and the payment
of interest on such advances and expenses.

                  Interest accrued on this Certificate during an Interest
Accrual Period, plus any unpaid interest shortfall with respect to this
Certificate for any prior Distribution Date, if any, will be payable on the
related Distribution Date to the extent provided in the Agreement. The "Interest
Accrual Period" with respect to any Distribution Date and with respect to the
Class Q Certificates is the calendar month preceding the month in which such
Distribution Date occurs and is assumed to consist of 30 days.

<PAGE>

                  Any distribution to the Holder of this Certificate in
reduction of the Certificate Principal Balance hereof is binding on such Holder
and all future Holders of this Certificate and any Certificate issued upon the
transfer hereof or in exchange herefor or in lieu hereof whether or not notation
of such distribution is made upon this Certificate.

                  The Class Q Certificates are issuable in fully registered form
only without coupons in minimum denominations specified in the Agreement. As
provided in the Agreement and subject to certain limitations therein set forth,
Class Q Certificates are exchangeable for new Class Q Certificates in authorized
denominations evidencing the same aggregate Percentage Interest, as requested by
the Holder surrendering the same.

                  As provided in the Agreement and subject to certain
limitations therein set forth, the transfer of this Certificate is registrable
in the Certificate Register upon surrender of this Certificate for registration
of transfer at the offices of the Certificate Registrar, duly endorsed by, or
accompanied by a written instrument of transfer in the form satisfactory to the
Certificate Registrar duly executed by, the Holder hereof or his attorney duly
authorized in writing, and thereupon one or more new Class Q Certificates in
authorized denominations evidencing the same aggregate Percentage Interest will
be issued to the designated transferee or transferees.

                  With respect to any offer, sale, pledge or other transfer of
any Class Q Certificate, no such transfer of a Class Q Certificate shall be made
unless that transfer is made pursuant to an effective registration statement
under the Securities Act, and effective registration or qualification under
applicable state securities laws, or is made in a transaction which does not
require such registration or qualification. If such a transfer is to be made
without registration under the Securities Act (other than in connection with the
initial issuance thereof or the initial transfer thereof by the Depositor, the
Underwriters or their respective affiliates), then the Certificate Registrar
shall refuse to register such transfer unless it receives either: (i) a
certificate from the Certificateholder desiring to effect such transfer
substantially in the form attached as Exhibit E-1 to the Agreement, and a
certificate from such Certificateholder's prospective transferee substantially
in the form attached as either Exhibit E-2 (which relates to sales to QIBs in
reliance on Rule 144A) or Exhibit E-3 (which relates to sales to Institutional
Accredited Investors) to the Agreement; or (ii) an Opinion of Counsel
satisfactory to the Certificate Registrar to the effect that such transfer may
be made without registration under the Securities Act (which Opinion of Counsel
shall not be an expense of the Trust Fund or of the Depositor, the Master
Servicer, the Special Servicer, the Trustee or the Certificate Registrar in
their respective capacities as such), together with the written certification(s)
as to the facts surrounding such transfer from the Certificateholder desiring to
effect such transfer and/or such Certificateholder's prospective transferee on
which such Opinion of Counsel is based. None of the Depositor, the Trustee or
the Certificate Registrar is obligated to register or qualify the Class Q
Certificates under the Securities Act or any other securities law or to take any
action not otherwise required under the Agreement to permit the transfer of any
Class Q Certificate without registration or qualification. Any Class Q
Certificateholder desiring to effect such a transfer shall, and by the
acceptance of its Class Q Certificate agrees to, indemnify the Trustee, the
Certificate Registrar and the Depositor against any liability that may result if
the transfer is not so exempt or is not made in accordance with such federal and
state laws.

<PAGE>

                  With respect to any offer, sale, pledge or other transfer of
any Class Q Certificate that constitutes a Class of Book-Entry Certificates, if
such a transfer is to be made without registration under the Securities Act,
such transfer will not be made unless the prospective transferee delivers to the
transferor (i) a certificate substantially in the form of Exhibit E-2 hereto and
addressed to the transferor, upon or prior to such transfer, or (ii) an opinion
of counsel to the effect that such transferee is a QIB and that such transfer
may be made without registration under the Securities Act, together with the
written certification(s) as to the facts surrounding such transfer, from the
prospective transferor desiring to effect such transfer and/or the prospective
transferee, on which such opinion of counsel is based. In any event, (a) each
prospective transferor of such Class Q Certificate will be deemed to have
represented to the Trustee, the Depositor and the transferee of such Certificate
the information set forth on Exhibit E-1 upon or prior to such transfer and (b)
each prospective transferee of such Certificate will be deemed to have
represented to the Trustee, the Depositor and the transferor of such Certificate
the information set forth on Exhibit E-2 hereto.

                  An Institutional Accredited Investor (other than a QIB) may
not hold an interest in a Class Q Certificate in book-entry form and must hold
such interest in a Class Q Certificate in definitive form. Any transfer of such
Certificates will require, among other things described herein and in the
Agreement, delivery of the certificates and/or opinions required in connection
with the transfer of a Class Q Certificate held in a physical certificated form,
as set forth above.

                  No service charge will be imposed for any registration of
transfer or exchange of Class Q Certificates, but the Certificate Registrar may
require payment of a sum sufficient to cover any tax or other governmental
charge that may be imposed in connection with any transfer or exchange of Class
Q Certificates.

                  Notwithstanding the foregoing, for so long as this Certificate
is registered in the name of Cede & Co. or in such other name as is requested by
an authorized representative of DTC, transfers of interests in this Certificate
shall be made through the book-entry facilities of DTC.

                  The Depositor, the Master Servicer, the Special Servicer, the
Trustee, and the Certificate Registrar and any agent of the Depositor, the
Master Servicer, the Special Servicer, the Trustee or the Certificate Registrar
may treat the Person in whose name this Certificate is registered as the owner
hereof for all purposes whatsoever and none of the Depositor, the Master
Servicer, the Special Servicer, the Trustee, the Certificate Registrar or any
such agent shall be affected by notice to the contrary.

                  The Trust Fund and the obligations created by the Agreement
shall terminate upon distribution (or provision for distribution) to the
Certificateholders of all amounts held by or on behalf of the Trustee and
required to be distributed to them pursuant to the Agreement following the
earlier to occur of (i) the final payment (or any advance with respect thereto)
or other liquidation of the last Mortgage Loan or REO Property remaining in the
Trust Fund, and (ii) the purchase by the Master Servicer, the Special Servicer
or the Majority Subordinate

<PAGE>

Certificateholder at a price determined as provided in the Agreement of all
Mortgage Loans and each REO Property remaining in the Trust Fund. The Agreement
permits, but does not require, the Master Servicer, the Special Servicer or the
Majority Subordinate Certificateholder to purchase from the Trust Fund all
Mortgage Loans and each REO Property remaining therein. The exercise of such
right will effect early retirement of the Class Q Certificates; however, such
right to purchase is subject to the aggregate Stated Principal Balance of the
Mortgage Pool at the time of purchase being less than 1% of the aggregate Stated
Principal Balance of the Mortgage Loans as of the Closing Date specified on the
face hereof.

                  The Agreement permits, with certain exceptions therein
provided, the amendment thereof and the modification of the rights and
obligations of the Depositor, the Master Servicer, the Special Servicer and the
Trustee and the rights of the Certificateholders under the Agreement at any time
by the Depositor, the Master Servicer, the Special Servicer and the Trustee with
the consent of the Holders of Certificates entitled to at least 51% of the
Voting Rights allocated to the affected Classes. Any such consent by the Holder
of this Certificate shall be conclusive and binding on such Holder and upon all
future Holders of this Certificate and of any Certificate issued upon the
transfer hereof or in exchange herefor or in lieu hereof whether or not notation
of such consent is made upon this Certificate. The Agreement also permits the
amendment thereof, in certain limited circumstances, including any amendment
necessary to maintain the status of the Trust Fund (or designated portions
thereof) as consisting of three separate REMICs and a grantor trust, without the
consent of the Holders of any of the Certificates.

                  Unless the certificate of authentication hereon has been
executed by the Certificate Registrar, by manual signature, this Certificate
shall not be entitled to any benefit under the Agreement or be valid for any
purpose.

                  The registered Holder hereof, by its acceptance hereof, agrees
that it will look solely to the Trust Fund (to the extent of its rights therein)
for distributions hereunder.

                  This Certificate shall be construed in accordance with the
internal laws of the State of New York applicable to agreements made and to be
performed in said State, and the obligations, rights and remedies of the Holder
hereof shall be determined in accordance with such laws.

                  IN WITNESS WHEREOF, the Certificate Registrar has caused this
Certificate to be duly executed.

                  An Institutional Accredited Investor (other than a QIB) may
not hold an interest in a Class WW-X Certificate in book-entry form and must
hold such interest in a Class WW-X Certificate in definitive form. Any transfer
of such Certificates will require, among other things described herein and in
the Agreement, delivery of the certificates and/or opinions required in
connection with the transfer of a Class WW-X Certificate held in a physical
certificated form, as set forth above.

                  No service charge will be imposed for any registration of
transfer or exchange of Class WW-X Certificates, but the Certificate Registrar
may require payment of a sum sufficient to cover any tax or other governmental
charge that may be imposed in connection with any transfer or exchange of Class
WW-X Certificates.

                  Notwithstanding the foregoing, for so long as this Certificate
is registered in the name of Cede & Co. or in such other name as is requested by
an authorized representative of DTC, transfers of interests in this Certificate
shall be made through the book-entry facilities of DTC.

                  The Depositor, the Master Servicer, the Special Servicer, the
Trustee, and the Certificate Registrar and any agent of the Depositor, the
Master Servicer, the Special Servicer, the Trustee, or the Certificate Registrar
may treat the Person in whose name this Certificate is registered as the owner
hereof for all purposes whatsoever and none of the Depositor, the Master

<PAGE>

Servicer, the Special Servicer, the Trustee, the Certificate Registrar or any
such agent shall be affected by notice to the contrary.

                  The Trust Fund and the obligations created by the Agreement
shall terminate upon distribution (or provision for distribution) to the
Certificateholders of all amounts held by or on behalf of the Trustee and
required to be distributed to them pursuant to the Agreement following the
earlier to occur of (i) the final payment (or any advance with respect thereto)
or other liquidation of the last Mortgage Loan or REO Property remaining in the
Trust Fund, including the 77 West Wacker Drive Non-Pooled Component, and (ii)
the purchase by the Master Servicer, the Special Servicer or the Majority
Subordinate Certificateholder at a price determined as provided in the Agreement
of all Mortgage Loans and each REO Property remaining in the Trust Fund. The
Agreement permits, but does not require, the Master Servicer, the Special
Servicer or the Majority Subordinate Certificateholder to purchase from the
Trust Fund all Mortgage Loans and each REO Property remaining therein. The
exercise of such right will effect early retirement of the Class WW-X
Certificates; however, such right to purchase is subject to the aggregate Stated
Principal Balance of the Mortgage Pool at the time of purchase being less than
1% of the aggregate Stated Principal Balance of the Mortgage Loans as of the
Closing Date specified on the face hereof.

                  The Agreement permits, with certain exceptions therein
provided, the amendment thereof and the modification of the rights and
obligations of the Depositor, the Master Servicer, the Special Servicer and the
Trustee and the rights of the Certificateholders under the Agreement at any time
by the Depositor, the Master Servicer, the Special Servicer, and the Trustee
with the consent of the Holders of Certificates entitled to at least 51% of the
Voting Rights allocated to the affected Classes. The Holder of this Certificate
is not entitled to any Voting Rights. The Agreement also permits the amendment
thereof, in certain limited circumstances, including any amendment necessary to
maintain the status of the Trust Fund (or designated portions thereof) as
consisting of three separate REMICs and a grantor trust, without the consent of
the Holders of any of the Certificates.

                  Unless the certificate of authentication hereon has been
executed by the Certificate Registrar, by manual signature, this Certificate
shall not be entitled to any benefit under the Agreement or be valid for any
purpose.

                  The registered Holder hereof, by its acceptance hereof, agrees
that it will look solely to the Trust Fund (to the extent of its rights therein)
for distributions hereunder.

                  This Certificate shall be construed in accordance with the
internal laws of the State of New York applicable to agreements made and to be
performed in said State, and the obligations, rights and remedies of the Holder
hereof shall be determined in accordance with such laws.

Certificate to be duly executed.

EXTENT PROVIDED IN THE POOLING AND SERVICING AGREEMENT.

CERTIFICATES AS PROVIDED IN THE POOLING AND SERVICING AGREEMENT. ACCORDINGLY,
THE CERTIFICATE PRINCIPAL BALANCE OF THIS CERTIFICATE MAY BE LESS THAN THAT SET

dividing the principal amount of this

<PAGE>

Class WW-1 Certificate (its "Certificate Principal Balance") as of the Closing
Date by the aggregate principal amount of all the Class WW-1 Certificates (their
"Class Principal Balance") as of the Closing Date) in that certain beneficial
ownership interest evidenced by all the Class WW-1 Certificates in the Trust
Fund created pursuant to a Pooling and Servicing Agreement, dated as specified
above (the "Agreement"), among Merrill Lynch Mortgage Investors, Inc. (herein
called the "Depositor", which term includes any successor entity under the
Agreement), KeyCorp Real Estate Capital Markets, Inc. (herein called the "Master
Servicer", which term includes any successor entity under the Agreement), ARCap
Servicing, Inc. (herein called the "Special Servicer", which term includes any
successor entity under the Agreement), LaSalle Bank National Association (herein
called the "Trustee", which term includes any successor entity under the
Agreement), and ABN AMRO Bank N.V. (herein called the "Fiscal Agent", which term
includes any successor entity under the Agreement), a summary of certain of the
pertinent provisions of which is set forth hereafter. To the extent not defined
herein, the capitalized terms used herein have the respective meanings assigned
in the Agreement. This Certificate is issued under and is subject to the terms,
provisions and conditions of the Agreement, to which Agreement the Holder of
this Certificate by virtue of the acceptance hereof assents and by which such
Holder is bound.

                  Pursuant to the terms of the Agreement, distributions will be
made on the 12th day of any given month, or if the 12th day is not a Business
Day, on the next succeeding Business Day (each, a "Distribution Date"). With
respect to each Distribution Date, the Determination Date is the 4th Business
Day prior to the Distribution Date (each, a "Determination Date"). Distributions
will be made commencing on the first Distribution Date specified above, to the
Person in whose name this Certificate is registered at the close of business on
the last Business Day of the month immediately preceding the month of such
distribution (the "Record Date"), in an amount equal to the product of the
Percentage Interest evidenced by this Certificate and the amount required to be
distributed to the Holders of the Class WW-1 Certificates on the applicable
Distribution Date pursuant to the Agreement. The aggregate amount available for
distribution on each Distribution Date to the Class WW Certificates is generally
limited to certain collections and recoveries respecting the 77 West Wacker
Drive Non-Pooled Component, as provided in the Agreement. All distributions made
under the Agreement on the Class WW-1 Certificates will be made by the Trustee,
by wire transfer of immediately available funds to the account of the Person
entitled thereto at a bank or other entity having appropriate facilities
therefor, if such Certificateholder shall have provided the Trustee with wiring
instructions no less than five Business Days prior to the related Record Date
(which wiring instructions may be in the form of a standing order applicable to
all subsequent distributions), or otherwise by check mailed to the address of
such Certificateholder as it appears in the Certificate Register.
Notwithstanding the foregoing, the final distribution on this Certificate
(determined without regard to any possible future reimbursement of any Realized
Loss or Additional Trust Fund Expense previously allocated to this Certificate)
will be made in like manner, but only upon presentation and surrender of this
Certificate at the offices of the Certificate Registrar or such other location
specified in the notice to the Holder hereof of such final distribution. All
Realized Losses and Additional Trust Fund Expenses relating to the 77 West
Wacker Drive Mortgage Loan and its pro rata share of certain Additional Trust
Fund Expenses not attributable to any particular Mortgage Loan, as provided in,
and subject to the terms of, the Agreement, will be

<PAGE>

allocated separately to the Class WW Principal Balance Certificates, as
described in the Agreement. Also notwithstanding the foregoing, any distribution
that may be made with respect to this Certificate in reimbursement of any
Realized Loss or Additional Trust Fund Expense previously allocated to this
Certificate, which reimbursement is to occur after the date on which this
Certificate is surrendered as contemplated by the preceding sentence, will be
made by check mailed to the address of the Holder that surrenders this
Certificate as such address last appears in the Certificate Register or to any
such other address of which the Trustee is subsequently notified in writing.

                  The Class WW Certificates, to which this Certificate belongs,
are limited in right of distribution to certain collections and recoveries
respecting the 77 West Wacker Drive Non-Pooled Component, all as more
specifically set forth herein and in the Agreement. As provided in the
Agreement, withdrawals from the Certificate Account, Interest Reserve Account,
the Gain on Sale Reserve Account, the 77 West Wacker Drive Distribution Account
and, if established, the REO Account may be made from time to time for purposes
other than, and, in certain cases, prior to, distributions to
Certificateholders, such purposes including the reimbursement of advances made,
or certain expenses incurred, with respect to the Mortgage Loans and the payment
of interest on such advances and expenses.

                  Interest accrued on this Certificate during an Interest
Accrual Period, plus any unpaid interest shortfall with respect to this
Certificate for any prior Distribution Date, if any, will be payable on the
related Distribution Date to the extent provided in the Agreement. The "Interest
Accrual Period" with respect to any Distribution Date and with respect to the
Class WW-1 Certificates is the calendar month preceding the month in which such
Distribution Date occurs and is assumed to consist of 30 days.

                  Any distribution to the Holder of this Certificate in
reduction of the Certificate Principal Balance hereof is binding on such Holder
and all future Holders of this Certificate and any Certificate issued upon the
transfer hereof or in exchange herefor or in lieu hereof whether or not notation
of such distribution is made upon this Certificate.

                  The Class WW-1 Certificates are issuable in fully registered
form only without coupons in minimum denominations specified in the Agreement.
As provided in the Agreement and subject to certain limitations therein set
forth, Class WW-1 Certificates are exchangeable for new Class WW-1 Certificates
in authorized denominations evidencing the same aggregate Percentage Interest,
as requested by the Holder surrendering the same.

                  As provided in the Agreement and subject to certain
limitations therein set forth, the transfer of this Certificate is registrable
in the Certificate Register upon surrender of this Certificate for registration
of transfer at the offices of the Certificate Registrar, duly endorsed by, or
accompanied by a written instrument of transfer in the form satisfactory to the
Certificate Registrar duly executed by, the Holder hereof or his attorney duly
authorized in writing, and thereupon one or more new Class WW-1 Certificates in
authorized denominations evidencing the same aggregate Percentage Interest will
be issued to the designated transferee or transferees.

<PAGE>

                  With respect to any offer, sale, pledge or other transfer of
any Class WW-1 Certificate, no such transfer of a Class WW-1 Certificate shall
be made unless that transfer is made pursuant to an effective registration
statement under the Securities Act, and effective registration or qualification
under applicable state securities laws, or is made in a transaction which does
not require such registration or qualification. If such a transfer is to be made
without registration under the Securities Act (other than in connection with the
initial issuance thereof or the initial transfer thereof by the Depositor, the
Underwriters or their respective affiliates), then the Certificate Registrar
shall refuse to register such transfer unless it receives either: (i) a
certificate from the Certificateholder desiring to effect such transfer
substantially in the form attached as Exhibit E-1 to the Agreement, and a
certificate from such Certificateholder's prospective transferee substantially
in the form attached as either Exhibit E-2 (which relates to sales to QIBs in
reliance on Rule 144A) or Exhibit E-3 (which relates to sales to Institutional
Accredited Investors) to the Agreement; or (ii) an Opinion of Counsel
satisfactory to the Certificate Registrar to the effect that such transfer may
be made without registration under the Securities Act (which Opinion of Counsel
shall not be an expense of the Trust Fund or of the Depositor, the Master
Servicer, the Special Servicer, the Trustee or the Certificate Registrar in
their respective capacities as such), together with the written certification(s)
as to the facts surrounding such transfer from the Certificateholder desiring to
effect such transfer and/or such Certificateholder's prospective transferee on
which such Opinion of Counsel is based. None of the Depositor, the Trustee or
the Certificate Registrar is obligated to register or qualify the Class WW-1
Certificates under the Securities Act or any other securities law or to take any
action not otherwise required under the Agreement to permit the transfer of any
Class WW-1 Certificate without registration or qualification. Any Class WW-1
Certificateholder desiring to effect such a transfer shall, and by the
acceptance of its Class WW-1 Certificate agrees to, indemnify the Trustee, the
Certificate Registrar and the Depositor against any liability that may result if
the transfer is not so exempt or is not made in accordance with such federal and
state laws.

                  With respect to any offer, sale, pledge or other transfer of
any Class WW-1 Certificate that constitutes a Class of Book-Entry Certificates,
if such a transfer is to be made without registration under the Securities Act,
such transfer will not be made unless the prospective transferee delivers to the
transferor (i) a certificate substantially in the form of Exhibit E-2 hereto and
addressed to the transferor, upon or prior to such transfer, or (ii) an opinion
of counsel to the effect that such transferee is a QIB and that such transfer
may be made without registration under the Securities Act, together with the
written certification(s) as to the facts surrounding such transfer, from the
prospective transferor desiring to effect such transfer and/or the prospective
transferee, on which such opinion of counsel is based. In any event, (a) each
prospective transferor of such Class WW-1 Certificate will be deemed to have
represented to the Trustee, the Depositor and the transferee of such Certificate
the information set forth on Exhibit E-1 upon or prior to such transfer and (b)
each prospective transferee of such Certificate will be deemed to have
represented to the Trustee, the Depositor and the transferor of such Certificate
the information set forth on Exhibit E-2 hereto.

                  An Institutional Accredited Investor (other than a QIB) may
not hold an interest in a Class WW-1 Certificate in book-entry form and must
hold such interest in a Class WW-1 Certificate in definitive form. Any transfer
of such Certificates will require, among other things

<PAGE>

described herein and in the Agreement, delivery of the certificates and/or
opinions required in connection with the transfer of a Class WW-1 Certificate
held in a physical certificated form, as set forth above.

                  No service charge will be imposed for any registration of
transfer or exchange of Class WW-1 Certificates, but the Certificate Registrar
may require payment of a sum sufficient to cover any tax or other governmental
charge that may be imposed in connection with any transfer or exchange of Class
WW-1 Certificates.

                  Notwithstanding the foregoing, for so long as this Certificate
is registered in the name of Cede & Co. or in such other name as is requested by
an authorized representative of DTC, transfers of interests in this Certificate
shall be made through the book-entry facilities of DTC.

                  The Depositor, the Master Servicer, the Special Servicer, the
Trustee, and the Certificate Registrar and any agent of the Depositor, the
Master Servicer, the Special Servicer, the Trustee or the Certificate Registrar
may treat the Person in whose name this Certificate is registered as the owner
hereof for all purposes whatsoever and none of the Depositor, the Master
Servicer, the Special Servicer, the Trustee, the Certificate Registrar or any
such agent shall be affected by notice to the contrary.

                  The Trust Fund and the obligations created by the Agreement
shall terminate upon distribution (or provision for distribution) to the
Certificateholders of all amounts held by or on behalf of the Trustee and
required to be distributed to them pursuant to the Agreement following the
earlier to occur of (i) the final payment (or any advance with respect thereto)
or other liquidation of the last Mortgage Loan or REO Property remaining in the
Trust Fund, including the 77 West Wacker Drive Non-Pooled Component, and (ii)
the purchase by the Master Servicer, the Special Servicer or the Majority
Subordinate Certificateholder at a price determined as provided in the Agreement
of all Mortgage Loans and each REO Property remaining in the Trust Fund. The
Agreement permits, but does not require, the Master Servicer, the Special
Servicer or the Majority Subordinate Certificateholder to purchase from the
Trust Fund all Mortgage Loans and each REO Property remaining therein. The
exercise of such right will effect early retirement of the Class WW-1
Certificates; however, such right to purchase is subject to the aggregate Stated
Principal Balance of the Mortgage Pool at the time of purchase being less than
1% of the aggregate Stated Principal Balance of the Mortgage Loans as of the
Closing Date specified on the face hereof.

                  The Agreement permits, with certain exceptions therein
provided, the amendment thereof and the modification of the rights and
obligations of the Depositor, the Master Servicer, the Special Servicer and the
Trustee and the rights of the Certificateholders under the Agreement at any time
by the Depositor, the Master Servicer, the Special Servicer and the Trustee with
the consent of the Holders of Certificates entitled to at least 51% of the
Voting Rights allocated to the affected Classes. The Holder of this Certificate
is not entitled to any Voting Rights. The Agreement also permits the amendment
thereof, in certain limited circumstances, including any

<PAGE>

amendment necessary to maintain the status of the Trust Fund (or designated
portions thereof) as consisting of three separate REMICs and a grantor trust,
without the consent of the Holders of any of the Certificates.

                  Unless the certificate of authentication hereon has been
executed by the Certificate Registrar, by manual signature, this Certificate
shall not be entitled to any benefit under the Agreement or be valid for any
purpose.

                  The registered Holder hereof, by its acceptance hereof, agrees
that it will look solely to the Trust Fund (to the extent of its rights therein)
for distributions hereunder.

                  This Certificate shall be construed in accordance with the
internal laws of the State of New York applicable to agreements made and to be
performed in said State, and the obligations, rights and remedies of the Holder
hereof shall be determined in accordance with such laws.

Class WW-2 Certificate (its "Certificate Principal Balance") as of the Closing

pertinent provisions of which is set forth hereafter. To the extent not defined
herein, the capitalized terms used herein have the respective meanings assigned
in the Agreement. This Certificate is issued under and is subject to the terms,
provisions and conditions of the Agreement, to which Agreement the Holder of
this Certificate by virtue of the acceptance hereof assents and by which such
Holder is bound.

                  Pursuant to the terms of the Agreement, distributions will be
made on the 12th day of any given month, or if the 12th day is not a Business
Day, on the next succeeding Business Day (each, a "Distribution Date"). With
respect to each Distribution Date, the Determination Date is the 4th Business
Day prior to the Distribution Date (each, a "Determination Date"). Distributions
will be made commencing on the first Distribution Date specified above, to the
Person in whose name this Certificate is registered at the close of business on
the last Business Day of the month immediately preceding the month of such
distribution (the "Record Date"), in an amount equal to the product of the
Percentage Interest evidenced by this Certificate and the amount required to be
distributed to the Holders of the Class WW-2 Certificates on the applicable
Distribution Date pursuant to the Agreement. The aggregate amount available for
distribution on each Distribution Date to the Class WW Certificates is generally
limited to certain collections and recoveries respecting the 77 West Wacker
Drive Non-Pooled Component, as provided in the Agreement. All distributions made
under the Agreement on the Class WW-2 Certificates will be made by the Trustee,
by wire transfer of immediately available funds to the account of the Person
entitled thereto at a bank or other entity having appropriate facilities
therefor, if such Certificateholder shall have provided the Trustee with wiring
instructions no less than five Business Days prior to the related Record Date
(which wiring instructions may be in the form of a standing order applicable to
all subsequent distributions), or otherwise by check mailed to the address of
such Certificateholder as it appears in the Certificate Register.
Notwithstanding the foregoing, the final distribution on this Certificate
(determined without regard to any possible future reimbursement of any Realized
Loss or Additional Trust Fund Expense previously allocated to this Certificate)
will be made in like manner, but only upon presentation and surrender of this
Certificate at the offices of the Certificate Registrar or such other location
specified in the notice to the Holder hereof of such final distribution. All
Realized Losses and Additional Trust Fund Expenses relating to the 77 West
Wacker Drive Mortgage Loan and its pro rata share of certain Additional Trust
Fund Expenses not attributable to any particular Mortgage Loan, as provided in,
and subject to the terms of, the Agreement, will be

<PAGE>

allocated separately to the Class WW Principal Balance Certificates, as
described in the Agreement. Also notwithstanding the foregoing, any distribution
that may be made with respect to this Certificate in reimbursement of any
Realized Loss or Additional Trust Fund Expense previously allocated to this
Certificate, which reimbursement is to occur after the date on which this
Certificate is surrendered as contemplated by the preceding sentence, will be
made by check mailed to the address of the Holder that surrenders this
Certificate as such address last appears in the Certificate Register or to any
such other address of which the Trustee is subsequently notified in writing.

                  The Class WW Certificates, to which this Certificate belongs,
are limited in right of distribution to certain collections and recoveries
respecting the 77 West Wacker Drive Non-Pooled Component, all as more
specifically set forth herein and in the Agreement. As provided in the
Agreement, withdrawals from the Certificate Account, Interest Reserve Account,
the Gain on Sale Reserve Account, the 77 West Wacker Drive Distribution Account
and, if established, the REO Account may be made from time to time for purposes
other than, and, in certain cases, prior to, distributions to
Certificateholders, such purposes including the reimbursement of advances made,
or certain expenses incurred, with respect to the Mortgage Loans and the payment
of interest on such advances and expenses.

                  Interest accrued on this Certificate during an Interest
Accrual Period, plus any unpaid interest shortfall with respect to this
Certificate for any prior Distribution Date, if any, will be payable on the
related Distribution Date to the extent provided in the Agreement. The "Interest
Accrual Period" with respect to any Distribution Date and with respect to the
Class WW-2 Certificates is the calendar month preceding the month in which such
Distribution Date occurs and is assumed to consist of 30 days.

                  Any distribution to the Holder of this Certificate in
reduction of the Certificate Principal Balance hereof is binding on such Holder
and all future Holders of this Certificate and any Certificate issued upon the
transfer hereof or in exchange herefor or in lieu hereof whether or not notation
of such distribution is made upon this Certificate.

                  The Class WW-2 Certificates are issuable in fully registered
form only without coupons in minimum denominations specified in the Agreement.
As provided in the Agreement and subject to certain limitations therein set
forth, Class WW-2 Certificates are exchangeable for new Class WW-2 Certificates
in authorized denominations evidencing the same aggregate Percentage Interest,
as requested by the Holder surrendering the same.

                  As provided in the Agreement and subject to certain
limitations therein set forth, the transfer of this Certificate is registrable
in the Certificate Register upon surrender of this Certificate for registration
of transfer at the offices of the Certificate Registrar, duly endorsed by, or
accompanied by a written instrument of transfer in the form satisfactory to the
Certificate Registrar duly executed by, the Holder hereof or his attorney duly
authorized in writing, and thereupon one or more new Class WW-2 Certificates in
authorized denominations evidencing the same aggregate Percentage Interest will
be issued to the designated transferee or transferees.

<PAGE>

                  With respect to any offer, sale, pledge or other transfer of
any Class WW-2 Certificate, no such transfer of a Class WW-2 Certificate shall
be made unless that transfer is made pursuant to an effective registration
statement under the Securities Act, and effective registration or qualification
under applicable state securities laws, or is made in a transaction which does
not require such registration or qualification. If such a transfer is to be made
without registration under the Securities Act (other than in connection with the
initial issuance thereof or the initial transfer thereof by the Depositor, the
Underwriters or their respective affiliates), then the Certificate Registrar
shall refuse to register such transfer unless it receives either: (i) a
certificate from the Certificateholder desiring to effect such transfer
substantially in the form attached as Exhibit E-1 to the Agreement, and a
certificate from such Certificateholder's prospective transferee substantially
in the form attached as either Exhibit E-2 (which relates to sales to QIBs in
reliance on Rule 144A) or Exhibit E-3 (which relates to sales to Institutional
Accredited Investors) to the Agreement; or (ii) an Opinion of Counsel
satisfactory to the Certificate Registrar to the effect that such transfer may
be made without registration under the Securities Act (which Opinion of Counsel
shall not be an expense of the Trust Fund or of the Depositor, the Master
Servicer, the Special Servicer, the Trustee or the Certificate Registrar in
their respective capacities as such), together with the written certification(s)
as to the facts surrounding such transfer from the Certificateholder desiring to
effect such transfer and/or such Certificateholder's prospective transferee on
which such Opinion of Counsel is based. None of the Depositor, the Trustee or
the Certificate Registrar is obligated to register or qualify the Class WW-2
Certificates under the Securities Act or any other securities law or to take any
action not otherwise required under the Agreement to permit the transfer of any
Class WW-2 Certificate without registration or qualification. Any Class WW-2
Certificateholder desiring to effect such a transfer shall, and by the
acceptance of its Class WW-2 Certificate agrees to, indemnify the Trustee, the
Certificate Registrar and the Depositor against any liability that may result if
the transfer is not so exempt or is not made in accordance with such federal and
state laws.

                  With respect to any offer, sale, pledge or other transfer of
any Class WW-2 Certificate that constitutes a Class of Book-Entry Certificates,
if such a transfer is to be made without registration under the Securities Act,
such transfer will not be made unless the prospective transferee delivers to the
transferor (i) a certificate substantially in the form of Exhibit E-2 hereto and
addressed to the transferor, upon or prior to such transfer, or (ii) an opinion
of counsel to the effect that such transferee is a QIB and that such transfer
may be made without registration under the Securities Act, together with the
written certification(s) as to the facts surrounding such transfer, from the
prospective transferor desiring to effect such transfer and/or the prospective
transferee, on which such opinion of counsel is based. In any event, (a) each
prospective transferor of such Class WW-2 Certificate will be deemed to have
represented to the Trustee, the Depositor and the transferee of such Certificate
the information set forth on Exhibit E-1 upon or prior to such transfer and (b)
each prospective transferee of such Certificate will be deemed to have
represented to the Trustee, the Depositor and the transferor of such Certificate
the information set forth on Exhibit E-2 hereto.

                  An Institutional Accredited Investor (other than a QIB) may
not hold an interest in a Class WW-2 Certificate in book-entry form and must
hold such interest in a Class WW-2 Certificate in definitive form. Any transfer
of such Certificates will require, among other things

<PAGE>

described herein and in the Agreement, delivery of the certificates and/or
opinions required in connection with the transfer of a Class WW-2 Certificate
held in a physical certificated form, as set forth above.

                  No service charge will be imposed for any registration of
transfer or exchange of Class WW-2 Certificates, but the Certificate Registrar
may require payment of a sum sufficient to cover any tax or other governmental
charge that may be imposed in connection with any transfer or exchange of Class
WW-2 Certificates.

                  Notwithstanding the foregoing, for so long as this Certificate
is registered in the name of Cede & Co. or in such other name as is requested by
an authorized representative of DTC, transfers of interests in this Certificate
shall be made through the book-entry facilities of DTC.

                  The Depositor, the Master Servicer, the Special Servicer, the
Trustee, and the Certificate Registrar and any agent of the Depositor, the
Master Servicer, the Special Servicer, the Trustee or the Certificate Registrar
may treat the Person in whose name this Certificate is registered as the owner
hereof for all purposes whatsoever and none of the Depositor, the Master
Servicer, the Special Servicer, the Trustee, the Certificate Registrar or any
such agent shall be affected by notice to the contrary.

                  The Trust Fund and the obligations created by the Agreement
shall terminate upon distribution (or provision for distribution) to the
Certificateholders of all amounts held by or on behalf of the Trustee and
required to be distributed to them pursuant to the Agreement following the
earlier to occur of (i) the final payment (or any advance with respect thereto)
or other liquidation of the last Mortgage Loan or REO Property remaining in the
Trust Fund, including the 77 West Wacker Drive Non-Pooled Component, and (ii)
the purchase by the Master Servicer, the Special Servicer or the Majority
Subordinate Certificateholder at a price determined as provided in the Agreement
of all Mortgage Loans and each REO Property remaining in the Trust Fund. The
Agreement permits, but does not require, the Master Servicer, the Special
Servicer or the Majority Subordinate Certificateholder to purchase from the
Trust Fund all Mortgage Loans and each REO Property remaining therein. The
exercise of such right will effect early retirement of the Class WW-2
Certificates; however, such right to purchase is subject to the aggregate Stated
Principal Balance of the Mortgage Pool at the time of purchase being less than
1% of the aggregate Stated Principal Balance of the Mortgage Loans as of the
Closing Date specified on the face hereof.

                  The Agreement permits, with certain exceptions therein
provided, the amendment thereof and the modification of the rights and
obligations of the Depositor, the Master Servicer, the Special Servicer and the
Trustee and the rights of the Certificateholders under the Agreement at any time
by the Depositor, the Master Servicer, the Special Servicer and the Trustee with
the consent of the Holders of Certificates entitled to at least 51% of the
Voting Rights allocated to the affected Classes. The Holder of this Certificate
is not entitled to any Voting Rights. The Agreement also permits the amendment
thereof, in certain limited circumstances, including any

<PAGE>

amendment necessary to maintain the status of the Trust Fund (or designated
portions thereof) as consisting of three separate REMICs and a grantor trust,
without the consent of the Holders of any of the Certificates.

                  Unless the certificate of authentication hereon has been
executed by the Certificate Registrar, by manual signature, this Certificate
shall not be entitled to any benefit under the Agreement or be valid for any
purpose.

                  The registered Holder hereof, by its acceptance hereof, agrees
that it will look solely to the Trust Fund (to the extent of its rights therein)
for distributions hereunder.

                  This Certificate shall be construed in accordance with the
internal laws of the State of New York applicable to agreements made and to be
performed in said State, and the obligations, rights and remedies of the Holder
hereof shall be determined in accordance with such laws.

                  IN WITNESS WHEREOF, the Certificate Registrar has caused this
Certificate to be duly executed.

Class WW-3 Certificate (its "Certificate Principal Balance") as of the Closing

"Class Principal Balance") as of the Closing Date) in that certain beneficial
ownership interest evidenced by all the Class WW-3 Certificates in the Trust

Servicer", which term includes any successor entity under the Agreement), ARCap
Servicing, Inc. (herein called the "Special Servicer", which term includes any
successor entity under the Agreement), LaSalle Bank National Association (herein
called the "Trustee", which term includes any successor entity under the
Agreement), and ABN AMRO Bank N.V. (herein called the "Fiscal Agent", which term

pertinent provisions of which is set forth hereafter. To the extent not defined
herein, the capitalized terms used herein have the respective meanings assigned
in the Agreement. This Certificate is issued under and is subject to the terms,
provisions and conditions of the Agreement, to which Agreement the Holder of
this Certificate by virtue of the acceptance hereof assents and by which such
Holder is bound.

                  Pursuant to the terms of the Agreement, distributions will be
made on the 12th day of any given month, or if the 12th day is not a Business
Day, on the next succeeding Business Day (each, a "Distribution Date"). With
respect to each Distribution Date, the Determination Date is the 4th Business
Day prior to the Distribution Date (each, a "Determination Date"). Distributions
will be made commencing on the first Distribution Date specified above, to the
Person in whose name this Certificate is registered at the close of business on

Distribution Date pursuant to the Agreement. The aggregate amount available for
distribution on each Distribution Date to the Class WW Certificates is generally

Drive Non-Pooled Component, as provided in the Agreement. All distributions made
under the Agreement on the Class WW-3 Certificates will be made by the Trustee,
by wire transfer of immediately available funds to the account of the Person
entitled thereto at a bank or other entity having appropriate facilities
therefor, if such Certificateholder shall have provided the Trustee with wiring
instructions no less than five Business Days prior to the related Record Date
(which wiring instructions may be in the form of a standing order applicable to
all subsequent distributions), or otherwise by check mailed to the address of
such Certificateholder as it appears in the Certificate Register.
Notwithstanding the foregoing, the final distribution on this Certificate
(determined without regard to any possible future reimbursement of any Realized
Loss or Additional Trust Fund Expense previously allocated to this Certificate)
will be made in like manner, but only upon presentation and surrender of this
Certificate at the offices of the Certificate Registrar or such other location
specified in the notice to the Holder hereof of such final distribution. All
Realized Losses and Additional Trust Fund Expenses relating to the 77 West
Wacker Drive Mortgage Loan and its pro rata share of certain Additional Trust
Fund Expenses not attributable to any particular Mortgage Loan, as provided in,
and subject to the terms of, the Agreement, will be

<PAGE>

allocated separately to the Class WW Principal Balance Certificates, as
described in the Agreement. Also notwithstanding the foregoing, any distribution
that may be made with respect to this Certificate in reimbursement of any
Realized Loss or Additional Trust Fund Expense previously allocated to this
Certificate, which reimbursement is to occur after the date on which this
Certificate is surrendered as contemplated by the preceding sentence, will be
made by check mailed to the address of the Holder that surrenders this
Certificate as such address last appears in the Certificate Register or to any
such other address of which the Trustee is subsequently notified in writing.

                  The Class WW Certificates, to which this Certificate belongs,
are limited in right of distribution to certain collections and recoveries
respecting the 77 West Wacker Drive Non-Pooled Component, all as more
specifically set forth herein and in the Agreement. As provided in the
Agreement, withdrawals from the Certificate Account, Interest Reserve Account,
the Gain on Sale Reserve Account, the 77 West Wacker Drive Distribution Account
and, if established, the REO Account may be made from time to time for purposes
other than, and, in certain cases, prior to, distributions to
Certificateholders, such purposes including the reimbursement of advances made,
or certain expenses incurred, with respect to the Mortgage Loans and the payment
of interest on such advances and expenses.

                  Interest accrued on this Certificate during an Interest
Accrual Period, plus any unpaid interest shortfall with respect to this
Certificate for any prior Distribution Date, if any, will be payable on the
related Distribution Date to the extent provided in the Agreement. The "Interest
Accrual Period" with respect to any Distribution Date and with respect to the
Class WW-3 Certificates is the calendar month preceding the month in which such
Distribution Date occurs and is assumed to consist of 30 days.

                  Any distribution to the Holder of this Certificate in
reduction of the Certificate Principal Balance hereof is binding on such Holder
and all future Holders of this Certificate and any Certificate issued upon the
transfer hereof or in exchange herefor or in lieu hereof whether or not notation
of such distribution is made upon this Certificate.

                  The Class WW-3 Certificates are issuable in fully registered
form only without coupons in minimum denominations specified in the Agreement.
As provided in the Agreement and subject to certain limitations therein set
forth, Class WW-3 Certificates are exchangeable for new Class WW-3 Certificates
in authorized denominations evidencing the same aggregate Percentage Interest,
as requested by the Holder surrendering the same.

                  As provided in the Agreement and subject to certain
limitations therein set forth, the transfer of this Certificate is registrable
in the Certificate Register upon surrender of this Certificate for registration
of transfer at the offices of the Certificate Registrar, duly endorsed by, or
accompanied by a written instrument of transfer in the form satisfactory to the
Certificate Registrar duly executed by, the Holder hereof or his attorney duly
authorized in writing, and thereupon one or more new Class WW-3 Certificates in
authorized denominations evidencing the same aggregate Percentage Interest will
be issued to the designated transferee or transferees.

<PAGE>

                  With respect to any offer, sale, pledge or other transfer of
any Class WW-3 Certificate, no such transfer of a Class WW-3 Certificate shall
be made unless that transfer is made pursuant to an effective registration
statement under the Securities Act, and effective registration or qualification
under applicable state securities laws, or is made in a transaction which does
not require such registration or qualification. If such a transfer is to be made
without registration under the Securities Act (other than in connection with the
initial issuance thereof or the initial transfer thereof by the Depositor, the
Underwriters or their respective affiliates), then the Certificate Registrar
shall refuse to register such transfer unless it receives either: (i) a
certificate from the Certificateholder desiring to effect such transfer
substantially in the form attached as Exhibit E-1 to the Agreement, and a
certificate from such Certificateholder's prospective transferee substantially
in the form attached as either Exhibit E-2 (which relates to sales to QIBs in
reliance on Rule 144A) or Exhibit E-3 (which relates to sales to Institutional
Accredited Investors) to the Agreement; or (ii) an Opinion of Counsel
satisfactory to the Certificate Registrar to the effect that such transfer may
be made without registration under the Securities Act (which Opinion of Counsel
shall not be an expense of the Trust Fund or of the Depositor, the Master
Servicer, the Special Servicer, the Trustee or the Certificate Registrar in
their respective capacities as such), together with the written certification(s)
as to the facts surrounding such transfer from the Certificateholder desiring to
effect such transfer and/or such Certificateholder's prospective transferee on
which such Opinion of Counsel is based. None of the Depositor, the Trustee or
the Certificate Registrar is obligated to register or qualify the Class WW-3
Certificates under the Securities Act or any other securities law or to take any
action not otherwise required under the Agreement to permit the transfer of any
Class WW-3 Certificate without registration or qualification. Any Class WW-3
Certificateholder desiring to effect such a transfer shall, and by the
acceptance of its Class WW-3 Certificate agrees to, indemnify the Trustee, the
Certificate Registrar and the Depositor against any liability that may result if
the transfer is not so exempt or is not made in accordance with such federal and
state laws.

                  With respect to any offer, sale, pledge or other transfer of
any Class WW-3 Certificate that constitutes a Class of Book-Entry Certificates,
if such a transfer is to be made without registration under the Securities Act,
such transfer will not be made unless the prospective transferee delivers to the
transferor (i) a certificate substantially in the form of Exhibit E-2 hereto and
addressed to the transferor, upon or prior to such transfer, or (ii) an opinion
of counsel to the effect that such transferee is a QIB and that such transfer
may be made without registration under the Securities Act, together with the
written certification(s) as to the facts surrounding such transfer, from the
prospective transferor desiring to effect such transfer and/or the prospective
transferee, on which such opinion of counsel is based. In any event, (a) each
prospective transferor of such Class WW-3 Certificate will be deemed to have
represented to the Trustee, the Depositor and the transferee of such Certificate
the information set forth on Exhibit E-1 upon or prior to such transfer and (b)
each prospective transferee of such Certificate will be deemed to have
represented to the Trustee, the Depositor and the transferor of such Certificate
the information set forth on Exhibit E-2 hereto.

                  An Institutional Accredited Investor (other than a QIB) may
not hold an interest in a Class WW-3 Certificate in book-entry form and must
hold such interest in a Class WW-3 Certificate in definitive form. Any transfer
of such Certificates will require, among other things

<PAGE>

described herein and in the Agreement, delivery of the certificates and/or
opinions required in connection with the transfer of a Class WW-3 Certificate
held in a physical certificated form, as set forth above.

                  No service charge will be imposed for any registration of
transfer or exchange of Class WW-3 Certificates, but the Certificate Registrar
may require payment of a sum sufficient to cover any tax or other governmental
charge that may be imposed in connection with any transfer or exchange of Class
WW-3 Certificates.

                  Notwithstanding the foregoing, for so long as this Certificate
is registered in the name of Cede & Co. or in such other name as is requested by
an authorized representative of DTC, transfers of interests in this Certificate
shall be made through the book-entry facilities of DTC.

                  The Depositor, the Master Servicer, the Special Servicer, the
Trustee, and the Certificate Registrar and any agent of the Depositor, the
Master Servicer, the Special Servicer, the Trustee or the Certificate Registrar
may treat the Person in whose name this Certificate is registered as the owner
hereof for all purposes whatsoever and none of the Depositor, the Master
Servicer, the Special Servicer, the Trustee, the Certificate Registrar or any
such agent shall be affected by notice to the contrary.

                  The Trust Fund and the obligations created by the Agreement
shall terminate upon distribution (or provision for distribution) to the
Certificateholders of all amounts held by or on behalf of the Trustee and
required to be distributed to them pursuant to the Agreement following the
earlier to occur of (i) the final payment (or any advance with respect thereto)
or other liquidation of the last Mortgage Loan or REO Property remaining in the
Trust Fund, including the 77 West Wacker Drive Non-Pooled Component, and (ii)
the purchase by the Master Servicer, the Special Servicer or the Majority
Subordinate Certificateholder at a price determined as provided in the Agreement
of all Mortgage Loans and each REO Property remaining in the Trust Fund. The
Agreement permits, but does not require, the Master Servicer, the Special
Servicer or the Majority Subordinate Certificateholder to purchase from the
Trust Fund all Mortgage Loans and each REO Property remaining therein. The
exercise of such right will effect early retirement of the Class WW-3
Certificates; however, such right to purchase is subject to the aggregate Stated
Principal Balance of the Mortgage Pool at the time of purchase being less than
1% of the aggregate Stated Principal Balance of the Mortgage Loans as of the
Closing Date specified on the face hereof.

                  The Agreement permits, with certain exceptions therein
provided, the amendment thereof and the modification of the rights and
obligations of the Depositor, the Master Servicer, the Special Servicer and the
Trustee and the rights of the Certificateholders under the Agreement at any time
by the Depositor, the Master Servicer, the Special Servicer and the Trustee with
the consent of the Holders of Certificates entitled to at least 51% of the
Voting Rights allocated to the affected Classes. The Holder of this Certificate
is not entitled to any Voting Rights. The Agreement also permits the amendment
thereof, in certain limited circumstances, including any

<PAGE>

amendment necessary to maintain the status of the Trust Fund (or designated
portions thereof) as consisting of three separate REMICs and a grantor trust,
without the consent of the Holders of any of the Certificates.

                  Unless the certificate of authentication hereon has been
executed by the Certificate Registrar, by manual signature, this Certificate
shall not be entitled to any benefit under the Agreement or be valid for any
purpose.

                  The registered Holder hereof, by its acceptance hereof, agrees
that it will look solely to the Trust Fund (to the extent of its rights therein)
for distributions hereunder.

                  This Certificate shall be construed in accordance with the
internal laws of the State of New York applicable to agreements made and to be
performed in said State, and the obligations, rights and remedies of the Holder
hereof shall be determined in accordance with such laws.

<PAGE>

                  IN WITNESS WHEREOF, the Certificate Registrar has caused this
Certificate to be duly executed.

respect to each Distribution Date, the Determination Date is the 4th Business
Day prior to the Distribution Date (each, a "Determination Date"). Distributions
will be made commencing on the first Distribution Date specified above, to the
Person in whose name this Certificate is registered at the close of business on
the last Business Day of the month immediately preceding the month of such
distribution (the "Record Date"), in an amount equal to the product of the
Percentage Interest evidenced by this Certificate and the amount, if any,
required to be distributed to the Holders of the Class R-LR Certificates on the
applicable Distribution Date pursuant to the Agreement. All distributions made
under the Agreement on this Class R-LR Certificate will be made by check mailed
to the address of the

<PAGE>

Person entitled thereto, as such name and address appear in the Certificate
Register. Notwithstanding the foregoing, the final distribution on this
Certificate will be made in like manner, but only upon presentation and
surrender of this Certificate at the offices of the Certificate Registrar or
such other location specified in the notice to Certificateholders of such final
distribution.

                  The Certificates are limited in right of distribution to
certain collections and recoveries respecting the Mortgage Loans, all as more
specifically set forth herein and in the Agreement. As provided in the
Agreement, withdrawals from the Certificate Account, the Distribution Account
and, if established, the REO Account may be made from time to time for purposes
other than, and, in certain cases, prior to, distributions to
Certificateholders, such purposes including the reimbursement of advances made,
or certain expenses incurred, with respect to the Mortgage Loans and the payment
of interest on such advances and expenses.

                  The Class R-LR Certificates are issuable in fully registered
form only without coupons in minimum denominations representing Percentage
Interests specified in the Agreement. As provided in the Agreement and subject
to certain limitations therein set forth, Class R-LR Certificates are
exchangeable for new Class R-LR Certificates in authorized denominations
evidencing the same aggregate Percentage Interest, as requested by the Holder
surrendering the same.

                  As provided in the Agreement and subject to certain
limitations therein set forth, the transfer of this Certificate is registrable
in the Certificate Register upon surrender of this Certificate for registration
of transfer at the offices of the Certificate Registrar, duly endorsed by, or
accompanied by a written instrument of transfer in the form satisfactory to the
Certificate Registrar duly executed by, the Holder hereof or his attorney duly
authorized in writing, and thereupon one or more new Class R-LR Certificates in
authorized denominations evidencing the same aggregate Percentage Interest will
be issued to the designated transferee or transferees.

                  With respect to any offer, sale, pledge or other transfer of
any Class R-LR Certificate, no such transfer of a Class R-LR Certificate shall
be made unless that transfer is made pursuant to an effective registration
statement under the Securities Act, and effective registration or qualification
under applicable state securities laws, or is made in a transaction which does
not require such registration or qualification. If a transfer of any R-LR
Certificate is to be made without registration under the Securities Act (other
than in connection with the initial issuance thereof or the initial transfer
thereof by the Depositor, the Underwriters or their affiliates), then the
Certificate Registrar shall refuse to register such transfer unless it receives
either: (i) a certificate from the Certificateholder desiring to effect such
transfer substantially in the form attached as Exhibit E-1 to the Agreement, and
a certificate from such Certificateholder's prospective transferee substantially
in the form attached as either Exhibit E-2 (which relates to sales to QIBs in
reliance on Rule 144A) or Exhibit E-3 (which relates to sales to Institutional
Accredited Investors) to the Agreement; or (ii) an Opinion of Counsel
satisfactory to the Certificate Registrar to the effect that such transfer may
be made without registration under the Securities Act (which Opinion of Counsel
shall not be an expense of the Trust Fund or of the Depositor, the Master
Servicer, the Special Servicer, the Trustee or the Certificate Registrar in

<PAGE>

their respective capacities as such), together with the written certification(s)
as to the facts surrounding such transfer from the Certificateholder desiring to
effect such transfer and/or such Certificateholder's prospective transferee on
which such Opinion of Counsel is based. None of the Depositor, the Trustee or
the Certificate Registrar is obligated to register or qualify the Class R-LR
Certificates under the Securities Act or any other securities law or to take any
action not otherwise required under the Agreement to permit the transfer of any
Class R-LR Certificate without registration or qualification. Any Class R-LR
Certificateholder desiring to effect such a transfer shall, and by the
acceptance of its Class R-LR Certificate agrees to, indemnify the Trustee, the
Certificate Registrar and the Depositor against any liability that may result if
the transfer is not so exempt or is not made in accordance with such federal and
state laws.

                  No transfer of this Class R-LR Certificate or any interest
therein shall be made to (A) a Plan or (B) any Person who is directly or
indirectly purchasing the Class R-LR Certificate or interest therein on behalf
of, as named fiduciary of, as trustee of, or with assets of a Plan (including,
without limitation, any insurance company using assets in its general or
separate account that may constitute assets of a Plan). As a condition to its
registration of transfer of this Class R-LR Certificate, the Certificate
Registrar shall have the right to require the prospective transferee of such
Certificate, if it is not a Plan or Person described in clause (B) of the
preceding sentence, to execute a certification to that effect substantially in
the form of Exhibit G-1 to the Agreement.

                  This Certificate represents an interest in the "residual
interest" in REMIC as defined in the Agreement. Each Person who has or who
acquires any Ownership Interest in this Certificate shall be deemed by the
acceptance or acquisition of such Ownership Interest to have agreed to be bound
by the provisions of Section 5.02(d) of the Agreement and, if any purported
Transferee shall become a Holder of this Certificate in violation of the
provisions of such Section 5.02(d), to have irrevocably authorized the Trustee,
under clause (ii)(A) of such Section 5.02(d) to deliver payments to a Person
other than such Person and to have irrevocably authorized the Certificate
Registrar under clause (ii)(B) of such Section 5.02(d) to negotiate the terms of
any mandatory sale and to execute all instruments of Transfer and to do all
other things necessary in connection with any such sale. Each Person holding or
acquiring any Ownership Interest in this Certificate must be a Permitted
Transferee and shall promptly notify the Master Servicer and the Certificate
Registrar of any change or impending change in its status as a Permitted
Transferee. In connection with any proposed Transfer of any Ownership Interest
in this Certificate, the Certificate Registrar shall require delivery to it, and
shall not register the Transfer of this Certificate until its receipt of, an
affidavit and agreement substantially in the form attached as Exhibit G-1 to the
Agreement (a "Transfer Affidavit and Agreement") from the proposed Transferee,
in form and substance satisfactory to the Certificate Registrar, representing
and warranting, among other things, that such Transferee is a Permitted
Transferee, that it is not acquiring its Ownership Interest in this Certificate
as a nominee, trustee or agent for any Person that is not a Permitted
Transferee, that for so long as it retains its Ownership Interest in this
Certificate, it will endeavor to remain a Permitted Transferee, and that it has
reviewed the provisions of Section 5.02(d) of the Agreement and agrees to be
bound by them. Notwithstanding the delivery of a Transfer Affidavit and
Agreement by a proposed Transferee, if a Responsible Officer of the Certificate
Registrar has actual knowledge that the proposed

<PAGE>

Transferee is not a Permitted Transferee, no Transfer of an Ownership Interest
in this Certificate to such proposed Transferee shall be effected. The proposed
Transferor must also state in the Transfer Affidavit and Agreement that (A) it
has historically paid its debts as they have come due and intends to continue to
pay its debts as they come due in the future, (B) it understands that it may
incur tax liabilities with respect to this certificate in excess of cash flows
generated thereby, (C)it intends to pay any taxes associated with holding this
certificate as they become due, and (D) it will not transfer this certificate to
any person or entity that does not provide a similar affidavit. Any purported
transfer to a disqualified organization or other person that is not a permitted
transferee or otherwise in violation of these restrictions shall be absolutely
null and void and shall vest no rights in any purported transferee. If this
certificate represents a "non-economic residual interest", as defined in
Treasury Regulations Section 1.860E-1(c), transfers of this certificate may be
disregarded for federal income tax purposes. In order to satisfy a regulatory
safe harbor under which such transfers will not be disregarded, the transferor
may be required, among other things, to satisfy itself as to the financial
condition of the proposed transferee and either to transfer at a minimum price
or to an eligible transferee as specified in regulations.

                  Each Person holding or acquiring any Ownership Interest in
this Certificate shall agree (x) to require a Transfer Affidavit and Agreement
from any other Person to whom such Person attempts to transfer its Ownership
Interest herein and (y) not to transfer its Ownership Interest unless it
provides to the Certificate Registrar a certificate substantially in the form
attached as Exhibit G-2 to the Agreement stating that, among other things, it
has no actual knowledge that such other Person is not a Permitted Transferee.
Each Person holding or acquiring an Ownership Interest in this Certificate, by
purchasing such Ownership Interest herein, agrees to give the Master Servicer
and the Trustee written notice that it is a "pass-through interest holder"
within the meaning of temporary Treasury Regulation Section 1.67-3T(a)(2)(i)(A)
immediately upon acquiring such Ownership Interest, if it is, or is holding such
Ownership Interest on behalf of, a "pass-through interest holder".

                  The provisions of Section 5.02(d) of the Agreement may be
modified, added to or eliminated, provided that there shall have been delivered
to the Certificate Registrar and the Master Servicer the following: (a) written
confirmation from each Rating Agency to the effect that the modification of,
addition to or elimination of such provisions will not cause such Rating Agency
to qualify, downgrade or withdraw its then-current ratings of any Class of
Certificates; and (b) an Opinion of Counsel, in form and substance satisfactory
to the Certificate Registrar and the Master Servicer, obtained at the expense of
the party seeking such modification of, addition to or elimination of such
provisions (but in no event at the expense of the Trust Fund), to the effect
that such modification of, addition to or elimination of such provisions will
not cause the Trust Fund to (x) cease to qualify as two REMICs or (y) be subject
to an entity-level tax caused by the transfer of this Class R-LR Certificate to
a Person which is not a Permitted Transferee, or cause a Person other than the
prospective Transferee to be subject to a REMIC-related tax caused by the
transfer of this Class R-LR Certificate to a Person which is not a Permitted
Transferee.

                  A "Permitted Transferee" is any Transferee other than a
"Disqualified Organization", a "Plan" or a "Non-United States Person". A
"Disqualified Organization" is any

<PAGE>

of (i) the United States or a possession thereof, any State or any political
subdivision thereof, or any agency or instrumentality of any of the foregoing
(other than an instrumentality which is a corporation if all of its activities
are subject to tax and, except for the FHLMC, a majority of its board of
directors is not selected by any such governmental unit), (ii) a foreign
government, international organization, or any agency or instrumentality of
either of the foregoing, (iii) any organization (except certain farmers'
cooperatives described in Section 521 of the Code) which is exempt from the tax
imposed by Chapter I of the Code (unless such organization is subject to the tax
imposed by Section 511 of the Code on unrelated business taxable income), (iv)
rural electric and telephone cooperatives described in Section 1381 of the Code
and (v) any other Person so designated by the Trustee or Certificate Registrar
based upon an Opinion of Counsel that the holding of an Ownership Interest in a
Class R-LR Certificate by such Person may cause the Trust Fund or any Person
having an Ownership Interest in any Class of Certificates (other than such
Person) to incur a liability for any federal tax imposed under the Code that
would not otherwise be imposed but for the Transfer of an Ownership Interest in
a Class R-LR Certificate to such Person. The terms "United States", "State" and
"international organization" shall have the meanings set forth in Section 7701
of the Code or successor provisions.

                  A "Non-United States Person" is any Person other than a United
States Person. A "United States Person" is a citizen or resident of the United
States, a corporation or partnership, including any entity treated as a
corporation or a partnership for United States federal income tax purposes,
created or organized in, or under the laws of, the United States, any state or
the District of Columbia (unless, in the case of a partnership, Treasury
regulations are enacted that provide otherwise), an estate whose income is
includable in gross income for United States federal income tax purposes
regardless of its source, or a trust if a court within the United States is able
to exercise primary supervision over the administration of the trust and one or
more United States Persons have the authority to control all substantial
decisions of the trust, all within the meaning of Section 7701(a)(30) of the
Code.

                  No service charge will be imposed for any registration of
transfer or exchange of Class R-LR Certificates, but the Certificate Registrar
may require payment of a sum sufficient to cover any tax or other governmental
charge that may be imposed in connection with any transfer or exchange of Class
R-LR Certificates.

                  The Depositor, the Master Servicer, the Special Servicer, the
Trustee and the Certificate Registrar and any agent of the Depositor, the Master
Servicer, the Special Servicer, the Trustee or the Certificate Registrar may
treat the Person in whose name this Certificate is registered as the owner
hereof for all purposes, and none of the Depositor, the Master Servicer, the
Special Servicer, the Trustee, the Certificate Registrar or any such agent shall
be affected by notice to the contrary.

                  The Trust Fund and the obligations created by the Agreement
shall terminate upon distribution (or provision for distribution) to the
Certificateholders of all amounts held by or on behalf of the Trustee and
required to be distributed to them pursuant to the Agreement following the
earlier to occur of (i) the final payment (or any advance with respect thereto)
or other liquidation of the last Mortgage Loan or REO Property remaining in the
Trust Fund, and

<PAGE>

(ii) the purchase by the Master Servicer, the Special Servicer or the Majority
Subordinate Certificateholder at a price determined as provided in the Agreement
of all Mortgage Loans and each REO Property remaining in the Trust Fund. The
Agreement permits, but does not require, the Master Servicer, the Special
Servicer or the Majority Subordinate Certificateholder to purchase from the
Trust Fund all Mortgage Loans and each REO Property remaining therein. The
exercise of such right will effect early retirement of the Certificates;
however, such right to purchase is subject to the aggregate Stated Principal
Balance of the Mortgage Pool at the time of purchase being less than 1% of the
aggregate Stated Principal Balance of the Mortgage Loans as of the Closing Date
specified on the face hereof.

                  The Agreement permits, with certain exceptions therein
provided, the amendment thereof and the modification of the rights and
obligations of the Depositor, the Master Servicer, the Special Servicer and the
Trustee and the rights of the Certificateholders under the Agreement at any time
by the Depositor, the Master Servicer, the Special Servicer and the Trustee with
the consent of the Holders of Certificates entitled to at least 51% of the
Voting Rights allocated to the affected Classes. The Holder of this Certificate
is not entitled to any Voting Rights.

                  The Agreement also permits the amendment thereof, in certain
limited circumstances, including any amendment necessary to maintain the status
of the Trust Fund (or designated portions thereof) as consisting of three
separate REMICs and a grantor trust, without the consent of the Holders of any
of the Certificates.

                  Unless the certificate of authentication hereon has been
executed by the Certificate Registrar, by manual signature, this Certificate
shall not be entitled to any benefit under the Agreement or be valid for any
purpose.

                  The registered Holder hereof, by its acceptance hereof, agrees
that it will look solely to the Trust Fund (to the extent of its rights therein)
for distributions hereunder.

                  This Certificate shall be construed in accordance with the
internal laws of the State of New York applicable to agreements made and to be
performed in said State, and the obligations, rights and remedies of the Holder
hereof shall be determined in accordance with such laws.

                  IN WITNESS WHEREOF, the Certificate Registrar has caused this
Certificate to be duly executed.

to the address of the Person entitled thereto, as such name and address appear
in the Certificate Register. Notwithstanding the foregoing, the final
distribution on this Certificate will be made in like manner, but only upon
presentation and surrender of this Certificate at the offices of the Certificate
Registrar or such other location specified in the notice to Certificateholders
of such final distribution.

                  The Certificates are limited in right of distribution to
certain collections and recoveries respecting the Mortgage Loans, all as more
specifically set forth herein and in the Agreement. As provided in the
Agreement, withdrawals from the Certificate Account, the Distribution Account
and, if established, the REO Account may be made from time to time for purposes
other than, and, in certain cases, prior to, distributions to
Certificateholders, such purposes including the reimbursement of advances made,
or certain expenses incurred, with respect to the Mortgage Loans and the payment
of interest on such advances and expenses.

                  The Class R-I Certificates are issuable in fully registered
form only without coupons in minimum denominations representing Percentage
Interests specified in the Agreement. As provided in the Agreement and subject
to certain limitations therein set forth, Class R-I Certificates are
exchangeable for new Class R-I Certificates in authorized denominations
evidencing the same aggregate Percentage Interest, as requested by the Holder
surrendering the same.

                  As provided in the Agreement and subject to certain
limitations therein set forth, the transfer of this Certificate is registrable
in the Certificate Register upon surrender of this Certificate for registration
of transfer at the offices of the Certificate Registrar, duly endorsed by, or
accompanied by a written instrument of transfer in the form satisfactory to the
Certificate Registrar duly executed by, the Holder hereof or his attorney duly
authorized in writing, and thereupon one or more new Class R-I Certificates in
authorized denominations evidencing the same aggregate Percentage Interest will
be issued to the designated transferee or transferees.

                  With respect to any offer, sale, pledge or other transfer of
any Class R-I Certificate, no such transfer of a Class R-I Certificate shall be
made unless that transfer is made pursuant to an effective registration
statement under the Securities Act, and effective registration or qualification
under applicable state securities laws, or is made in a transaction which does
not require such registration or qualification. If a transfer of any R-I
Certificate is to be made without registration under the Securities Act (other
than in connection with the initial issuance thereof or the initial transfer
thereof by the Depositor, the Underwriters or their affiliates), then the
Certificate Registrar shall refuse to register such transfer unless it receives
either: (i) a certificate from the Certificateholder desiring to effect such
transfer substantially in the form attached as Exhibit E-1 to the Agreement, and
a certificate from such Certificateholder's prospective transferee substantially
in the form attached as either Exhibit E-2 (which relates to sales to QIBs in
reliance on Rule 144A) or Exhibit E-3 (which relates to sales to Institutional
Accredited Investors) to the Agreement; or (ii) an Opinion of Counsel
satisfactory to the Certificate Registrar to the effect that such transfer may
be made without registration under the

<PAGE>

Securities Act (which Opinion of Counsel shall not be an expense of the Trust
Fund or of the Depositor, the Master Servicer, the Special Servicer, the Trustee
or the Certificate Registrar in their respective capacities as such), together
with the written certification(s) as to the facts surrounding such transfer from
the Certificateholder desiring to effect such transfer and/or such
Certificateholder's prospective transferee on which such Opinion of Counsel is
based. None of the Depositor, the Trustee or the Certificate Registrar is
obligated to register or qualify the Class R-I Certificates under the Securities
Act or any other securities law or to take any action not otherwise required
under the Agreement to permit the transfer of any Class R-I Certificate without
registration or qualification. Any Class R-I Certificateholder desiring to
effect such a transfer shall, and by the acceptance of its Class R-I Certificate
agrees to, indemnify the Trustee, the Certificate Registrar and the Depositor
against any liability that may result if the transfer is not so exempt or is not
made in accordance with such federal and state laws.

                  No transfer of this Class R-I Certificate or any interest
therein shall be made to (A) a Plan or (B) any Person who is directly or
indirectly purchasing the Class R-I Certificate or interest therein on behalf
of, as named fiduciary of, as trustee of, or with assets of a Plan (including,
without limitation, any insurance company using assets in its general or
separate account that may constitute assets of a Plan). As a condition to its
registration of transfer of this Class R-I Certificate, the Certificate
Registrar shall have the right to require the prospective transferee of such
Certificate, if it is not a Plan or Person described in clause (B) of the
preceding sentence, to execute a certification to that effect substantially in
the form of Exhibit G-1 to the Agreement.

                  This Certificate represents an interest in the "residual
interest" in REMIC as defined in the Agreement. Each Person who has or who
acquires any Ownership Interest in this Certificate shall be deemed by the
acceptance or acquisition of such Ownership Interest to have agreed to be bound
by the provisions of Section 5.02(d) of the Agreement and, if any purported
Transferee shall become a Holder of this Certificate in violation of the
provisions of such Section 5.02(d), to have irrevocably authorized the Trustee,
under clause (ii)(A) of such Section 5.02(d) to deliver payments to a Person
other than such Person and to have irrevocably authorized the Certificate
Registrar under clause (ii)(B) of such Section 5.02(d) to negotiate the terms of
any mandatory sale and to execute all instruments of Transfer and to do all
other things necessary in connection with any such sale. Each Person holding or
acquiring any Ownership Interest in this Certificate must be a Permitted
Transferee and shall promptly notify the Master Servicer and the Certificate
Registrar of any change or impending change in its status as a Permitted
Transferee. In connection with any proposed Transfer of any Ownership Interest
in this Certificate, the Certificate Registrar shall require delivery to it, and
shall not register the Transfer of this Certificate until its receipt of, an
affidavit and agreement substantially in the form attached as Exhibit G-1 to the
Agreement (a "Transfer Affidavit and Agreement") from the proposed Transferee,
in form and substance satisfactory to the Certificate Registrar, representing
and warranting, among other things, that such Transferee is a Permitted
Transferee, that it is not acquiring its Ownership Interest in this Certificate
as a nominee, trustee or agent for any Person that is not a Permitted
Transferee, that for so long as it retains its Ownership Interest in this
Certificate, it will endeavor to remain a Permitted Transferee, and that it has
reviewed the provisions of Section 5.02(d) of the Agreement and agrees to be
bound by them.

<PAGE>

Notwithstanding the delivery of a Transfer Affidavit and Agreement by a proposed
Transferee, if a Responsible Officer of the Certificate Registrar has actual
knowledge that the proposed Transferee is not a Permitted Transferee, no
Transfer of an Ownership Interest in this Certificate to such proposed
Transferee shall be effected. The proposed Transferor must also state in the
Transfer Affidavit and Agreement that (A) it has historically paid its debts as
they have come due and intends to continue to pay its debts as they come due in
the future, (B) it understands that it may incur tax liabilities with respect to
this certificate in excess of cash flows generated thereby, (C)it intends to pay
any taxes associated with holding this certificate as they become due, and (D)
it will not transfer this certificate to any person or entity that does not
provide a similar affidavit. Any purported transfer to a disqualified
organization or other person that is not a permitted transferee or otherwise in
violation of these restrictions shall be absolutely null and void and shall vest
no rights in any purported transferee. If this certificate represents a
"non-economic residual interest", as defined in Treasury Regulations Section
1.860E-1(c), transfers of this certificate may be disregarded for federal income
tax purposes. In order to satisfy a regulatory safe harbor under which such
transfers will not be disregarded, the transferor may be required, among other
things, to satisfy itself as to the financial condition of the proposed
transferee and either to transfer at a minimum price or to an eligible
transferee as specified in regulations.

                  Each Person holding or acquiring any Ownership Interest in
this Certificate shall agree (x) to require a Transfer Affidavit and Agreement
from any other Person to whom such Person attempts to transfer its Ownership
Interest herein and (y) not to transfer its Ownership Interest unless it
provides to the Certificate Registrar a certificate substantially in the form
attached as Exhibit G-2 to the Agreement stating that, among other things, it
has no actual knowledge that such other Person is not a Permitted Transferee.
Each Person holding or acquiring an Ownership Interest in this Certificate, by
purchasing such Ownership Interest herein, agrees to give the Master Servicer
and the Trustee written notice that it is a "pass-through interest holder"
within the meaning of temporary Treasury Regulation Section 1.67-3T(a)(2)(i)(A)
immediately upon acquiring such Ownership Interest, if it is, or is holding such
Ownership Interest on behalf of, a "pass-through interest holder".

                  The provisions of Section 5.02(d) of the Agreement may be
modified, added to or eliminated, provided that there shall have been delivered
to the Certificate Registrar and the Master Servicer the following: (a) written
confirmation from each Rating Agency to the effect that the modification of,
addition to or elimination of such provisions will not cause such Rating Agency
to qualify, downgrade or withdraw its then-current ratings of any Class of
Certificates; and (b) an Opinion of Counsel, in form and substance satisfactory
to the Certificate Registrar and the Master Servicer, obtained at the expense of
the party seeking such modification of, addition to or elimination of such
provisions (but in no event at the expense of the Trust Fund), to the effect
that such modification of, addition to or elimination of such provisions will
not cause the Trust Fund to (x) cease to qualify as two REMICs or (y) be subject
to an entity-level tax caused by the transfer of this Class R-I Certificate to a
Person which is not a Permitted Transferee, or cause a Person other than the
prospective Transferee to be subject to a REMIC-related tax caused by the
transfer of this Class R-I Certificate to a Person which is not a Permitted
Transferee.

<PAGE>

                  A "Permitted Transferee" is any Transferee other than a
"Disqualified Organization", a "Plan" or a "Non-United States Person". A
"Disqualified Organization" is any of (i) the United States or a possession
thereof, any State or any political subdivision thereof, or any agency or
instrumentality of any of the foregoing (other than an instrumentality which is
a corporation if all of its activities are subject to tax and, except for the
FHLMC, a majority of its board of directors is not selected by any such
governmental unit), (ii) a foreign government, international organization, or
any agency or instrumentality of either of the foregoing, (iii) any organization
(except certain farmers' cooperatives described in Section 521 of the Code)
which is exempt from the tax imposed by Chapter I of the Code (unless such
organization is subject to the tax imposed by Section 511 of the Code on
unrelated business taxable income), (iv) rural electric and telephone
cooperatives described in Section 1381 of the Code and (v) any other Person so
designated by the Trustee or Certificate Registrar based upon an Opinion of
Counsel that the holding of an Ownership Interest in a Class R-I Certificate by
such Person may cause the Trust Fund or any Person having an Ownership Interest
in any Class of Certificates (other than such Person) to incur a liability for
any federal tax imposed under the Code that would not otherwise be imposed but
for the Transfer of an Ownership Interest in a Class R-I Certificate to such
Person. The terms "United States", "State" and "international organization"
shall have the meanings set forth in Section 7701 of the Code or successor
provisions.

                  A "Non-United States Person" is any Person other than a United
States Person. A "United States Person" is a citizen or resident of the United
States, a corporation or partnership, including any entity treated as a
corporation or a partnership for United States federal income tax purposes,
created or organized in, or under the laws of, the United States, any state or
the District of Columbia (unless, in the case of a partnership, Treasury
regulations are enacted that provide otherwise), an estate whose income is
includable in gross income for United States federal income tax purposes
regardless of its source, or a trust if a court within the United States is able
to exercise primary supervision over the administration of the trust and one or
more United States Persons have the authority to control all substantial
decisions of the trust, all within the meaning of Section 7701(a)(30) of the
Code.

                  No service charge will be imposed for any registration of
transfer or exchange of Class R-I Certificates, but the Certificate Registrar
may require payment of a sum sufficient to cover any tax or other governmental
charge that may be imposed in connection with any transfer or exchange of Class
R-I Certificates.

                  The Depositor, the Master Servicer, the Special Servicer, the
Trustee and the Certificate Registrar and any agent of the Depositor, the Master
Servicer, the Special Servicer, the Trustee or the Certificate Registrar may
treat the Person in whose name this Certificate is registered as the owner
hereof for all purposes, and none of the Depositor, the Master Servicer, the
Special Servicer, the Trustee, the Certificate Registrar or any such agent shall
be affected by notice to the contrary.

                  The Trust Fund and the obligations created by the Agreement
shall terminate upon distribution (or provision for distribution) to the
Certificateholders of all amounts held by or on behalf of the Trustee and
required to be distributed to them pursuant to the Agreement

<PAGE>

following the earlier to occur of (i) the final payment (or any advance with
respect thereto) or other liquidation of the last Mortgage Loan or REO Property
remaining in the Trust Fund, and (ii) the purchase by the Master Servicer, the
Special Servicer or the Majority Subordinate Certificateholder at a price
determined as provided in the Agreement of all Mortgage Loans and each REO
Property remaining in the Trust Fund. The Agreement permits, but does not
require, the Master Servicer, the Special Servicer or the Majority Subordinate
Certificateholder to purchase from the Trust Fund all Mortgage Loans and each
REO Property remaining therein. The exercise of such right will effect early
retirement of the Certificates; however, such right to purchase is subject to
the aggregate Stated Principal Balance of the Mortgage Pool at the time of
purchase being less than 1% of the aggregate Stated Principal Balance of the
Mortgage Loans as of the Closing Date specified on the face hereof.

                  The Agreement permits, with certain exceptions therein
provided, the amendment thereof and the modification of the rights and
obligations of the Depositor, the Master Servicer, the Special Servicer and the
Trustee and the rights of the Certificateholders under the Agreement at any time
by the Depositor, the Master Servicer, the Special Servicer and the Trustee with
the consent of the Holders of Certificates entitled to at least 51% of the
Voting Rights allocated to the affected Classes. The Holder of this Certificate
is not entitled to any Voting Rights.

                  The Agreement also permits the amendment thereof, in certain
limited circumstances, including any amendment necessary to maintain the status
of the Trust Fund (or designated portions thereof) as consisting of three
separate REMICs and a grantor trust, without the consent of the Holders of any
of the Certificates.

                  Unless the certificate of authentication hereon has been
executed by the Certificate Registrar, by manual signature, this Certificate
shall not be entitled to any benefit under the Agreement or be valid for any
purpose.

                  The registered Holder hereof, by its acceptance hereof, agrees
that it will look solely to the Trust Fund (to the extent of its rights therein)
for distributions hereunder.

                  This Certificate shall be construed in accordance with the
internal laws of the State of New York applicable to agreements made and to be
performed in said State, and the obligations, rights and remedies of the Holder
hereof shall be determined in accordance with such laws.

                  IN WITNESS WHEREOF, the Certificate Registrar has caused this
Certificate to be duly executed.

other than, and, in certain cases, prior to, distributions to
Certificateholders, such purposes including the reimbursement of advances made,
or certain expenses incurred, with respect to the Mortgage Loans and the payment
of interest on such advances and expenses.

                  The Class R-II Certificates are issuable in fully registered
form only without coupons in minimum denominations representing Percentage
Interests specified in the Agreement. As provided in the Agreement and subject
to certain limitations therein set forth, Class R-II Certificates are
exchangeable for new Class R-II Certificates in authorized denominations
evidencing the same aggregate Percentage Interest, as requested by the Holder
surrendering the same.

                  As provided in the Agreement and subject to certain
limitations therein set forth, the transfer of this Certificate is registrable
in the Certificate Register upon surrender of this Certificate for registration
of transfer at the offices of the Certificate Registrar, duly endorsed by, or
accompanied by a written instrument of transfer in the form satisfactory to the
Certificate Registrar duly executed by, the Holder hereof or his attorney duly
authorized in writing, and thereupon one or more new Class R-II Certificates in
authorized denominations evidencing the same aggregate Percentage Interest will
be issued to the designated transferee or transferees.

                  With respect to any offer, sale, pledge or other transfer of
any Class R-II Certificate, no such transfer of any Class R-II Certificate shall
be made unless that transfer is made pursuant to an effective registration
statement under the Securities Act, and effective registration or qualification
under applicable state securities laws, or is made in a transaction which does
not require such registration or qualification. If a transfer of any R-II
Certificate is to be made without registration under the Securities Act (other
than in connection with the initial issuance thereof or the initial transfer
thereof by the Depositor, the Underwriters or their affiliates), then the
Certificate Registrar shall refuse to register such transfer unless it receives
either: (i) a certificate from the Certificateholder desiring to effect such
transfer substantially in the form attached as Exhibit E-1 to the Agreement, and
a certificate from such Certificateholder's prospective transferee substantially
in the form attached as either Exhibit E-2 (which relates to sales to QIBs in
reliance on Rule 144A) or Exhibit E-3 (which relates to sales to Institutional
Accredited Investors) to the Agreement; or (ii) an Opinion of Counsel
satisfactory to the Certificate Registrar to the effect that such transfer may
be made without registration under the Securities Act (which Opinion of Counsel
shall not be an expense of the Trust Fund or of the Depositor, the Master
Servicer, the Special Servicer, the Trustee or the Certificate Registrar in

<PAGE>

their respective capacities as such), together with the written certification(s)
as to the facts surrounding such transfer from the Certificateholder desiring to
effect such transfer and/or such Certificateholder's prospective transferee on
which such Opinion of Counsel is based. None of the Depositor, the Trustee or
the Certificate Registrar is obligated to register or qualify the Class R-II
Certificates under the Securities Act or any other securities law or to take any
action not otherwise required under the Agreement to permit the transfer of any
Class R-II Certificate without registration or qualification. Any Class R-II
Certificateholder desiring to effect such a transfer shall, and by the
acceptance of its Class R-II Certificate agrees to, indemnify the Trustee, the
Certificate Registrar and the Depositor against any liability that may result if
the transfer is not so exempt or is not made in accordance with such federal and
state laws.

                  No transfer of this Class R-II Certificate or any interest
therein shall be made to (A) a Plan or (B) any Person who is directly or
indirectly purchasing the Class R-II Certificate or interest therein on behalf
of, as named fiduciary of, as trustee of, or with assets of a Plan (including,
without limitation, any insurance company using assets in its general or
separate account that may constitute assets of a Plan). As a condition to its
registration of transfer of this Class R-II Certificate, the Certificate
Registrar shall have the right to require the prospective transferee of such
Certificate, if it is not a Plan or Person described in clause (B) of the
preceding sentence, to execute a certification to that effect substantially in
the form of Exhibit G-1 to the Agreement.

                  This Certificate represents an interest in the "residual
interest" in REMIC II, as defined in the Agreement. Each Person who has or who
acquires any Ownership Interest in this Certificate shall be deemed by the
acceptance or acquisition of such Ownership Interest to have agreed to be bound
by the provisions of Section 5.02(d) of the Agreement and, if any purported
Transferee shall become a Holder of this Certificate in violation of the
provisions of such Section 5.02(d), to have irrevocably authorized the Trustee,
under clause (ii)(A) of such Section 5.02(d) to deliver payments to a Person
other than such Person and to have irrevocably authorized the Certificate
Registrar under clause (ii)(B) of such Section 5.02(d) to negotiate the terms of
any mandatory sale and to execute all instruments of Transfer and to do all
other things necessary in connection with any such sale. Each Person holding or
acquiring any Ownership Interest in this Certificate must be a Permitted
Transferee and shall promptly notify the Master Servicer and the Certificate
Registrar of any change or impending change in its status as a Permitted
Transferee. In connection with any proposed Transfer of any Ownership Interest
in this Certificate, the Certificate Registrar shall require delivery to it, and
shall not register the Transfer of this Certificate until its receipt of, an
affidavit and agreement substantially in the form attached as Exhibit G-1 to the
Agreement (a "Transfer Affidavit and Agreement") from the proposed Transferee,
in form and substance satisfactory to the Certificate Registrar, representing
and warranting, among other things, that such Transferee is a Permitted
Transferee, that it is not acquiring its Ownership Interest in this Certificate
as a nominee, trustee or agent for any Person that is not a Permitted
Transferee, that for so long as it retains its Ownership Interest in this
Certificate, it will endeavor to remain a Permitted Transferee, and that it has
reviewed the provisions of Section 5.02(d) of the Agreement and agrees to be
bound by them. Notwithstanding the delivery of a Transfer Affidavit and
Agreement by a proposed Transferee, if a Responsible Officer of the Certificate
Registrar has actual knowledge that the proposed

<PAGE>

Transferee is not a Permitted Transferee, no Transfer of an Ownership Interest
in this Certificate to such proposed Transferee shall be effected. The proposed
Transferor must also state in the Transfer Affidavit and Agreement that (A) it
has historically paid its debts as they have come due and intends to continue to
pay its debts as they come due in the future, (B) it understands that it may
incur tax liabilities with respect to this certificate in excess of cash flows
generated thereby, (C)it intends to pay any taxes associated with holding this
certificate as they become due, and (D) it will not transfer this certificate to
any person or entity that does not provide a similar affidavit. Any purported
transfer to a disqualified organization or other person that is not a permitted
transferee or otherwise in violation of these restrictions shall be absolutely
null and void and shall vest no rights in any purported transferee. If this
certificate represents a "non-economic residual interest", as defined in
Treasury Regulations Section 1.860E-1(c), transfers of this certificate may be
disregarded for federal income tax purposes. In order to satisfy a regulatory
safe harbor under which such transfers will not be disregarded, the transferor
may be required, among other things, to satisfy itself as to the financial
condition of the proposed transferee and either to transfer at a minimum price
or to an eligible transferee as specified in regulations.

                  Each Person holding or acquiring any Ownership Interest in
this Certificate shall agree (x) to require a Transfer Affidavit and Agreement
from any other Person to whom such Person attempts to transfer its Ownership
Interest herein and (y) not to transfer its Ownership Interest unless it
provides to the Certificate Registrar a certificate substantially in the form
attached as Exhibit G-2 to the Agreement stating that, among other things, it
has no actual knowledge that such other Person is not a Permitted Transferee.
Each Person holding or acquiring an Ownership Interest in this Certificate, by
purchasing such Ownership Interest herein, agrees to give the Master Servicer
and the Trustee written notice that it is a "pass-through interest holder"
within the meaning of temporary Treasury Regulation Section 1.67-3T(a)(2)(i)(A)
immediately upon acquiring such Ownership Interest, if it is, or is holding such
Ownership Interest on behalf of, a "pass-through interest holder".

                  The provisions of Section 5.02(d) of the Agreement may be
modified, added to or eliminated, provided that there shall have been delivered
to the Certificate Registrar and the Master Servicer the following: (a) written
confirmation from each Rating Agency to the effect that the modification of,
addition to or elimination of such provisions will not cause such Rating Agency
to qualify, downgrade or withdraw its then-current ratings of any Class of
Certificates; and (b) an Opinion of Counsel, in form and substance satisfactory
to the Certificate Registrar and the Master Servicer, obtained at the expense of
the party seeking such modification of, addition to or elimination of such
provisions (but in no event at the expense of the Trust Fund), to the effect
that such modification of, addition to or elimination of such provisions will
not cause the Trust Fund to (x) cease to qualify as two REMICs or (y) be subject
to an entity-level tax caused by the Transfer of any Class R-II Certificate to a
Person which is not a Permitted Transferee, or cause a Person other than the
prospective Transferee to be subject to a REMIC-related tax caused by the
transfer of this Class R-II Certificate to a Person which is not a Permitted
Transferee.

                  A "Permitted Transferee" is any Transferee other than a
"Disqualified Organization", a "Plan" or a "Non-United States Person". A
"Disqualified Organization" is any

<PAGE>

of (i) the United States or a possession thereof, any State or any political
subdivision thereof, or any agency or instrumentality of any of the foregoing
(other than an instrumentality which is a corporation if all of its activities
are subject to tax and, except for the FHLMC, a majority of its board of
directors is not selected by any such governmental unit), (ii) a foreign
government, international organization, or any agency or instrumentality of
either of the foregoing, (iii) any organization (except certain farmers'
cooperatives described in Section 521 of the Code) which is exempt from the tax
imposed by Chapter I of the Code (unless such organization is subject to the tax
imposed by Section 511 of the Code on unrelated business taxable income), (iv)
rural electric and telephone cooperatives described in Section 1381 of the Code
and (v) any other Person so designated by the Trustee or Certificate Registrar
based upon an Opinion of Counsel that the holding of an Ownership Interest in a
Class R-II Certificate by such Person may cause the Trust Fund or any Person
having an Ownership Interest in any Class of Certificates (other than such
Person) to incur a liability for any federal tax imposed under the Code that
would not otherwise be imposed but for the Transfer of an Ownership Interest in
a Class R-II Certificate to such Person. The terms "United States", "State" and
"international organization" shall have the meanings set forth in Section 7701
of the Code or successor provisions.

                  A "Non-United States Person" is any Person other than a United
States Person. A "United States Person" is a citizen or resident of the United
States, a corporation or partnership, including any entity treated as a
corporation or a partnership for United States federal income tax purposes,
created or organized in, or under the laws of, the United States, any state or
the District of Columbia (unless, in the case of a partnership, Treasury
regulations are enacted that provide otherwise), an estate whose income from is
includable in gross income for United States federal income tax purposes
regardless of its source, or a trust if a court within the United States is able
to exercise primary supervision over the administration of the trust and one or
more United States persons have the authority to control all substantial
decisions of the trust, all within the meaning of Section 7701(a)(30) of the
Code.

                  No service charge will be imposed for any registration of
transfer or exchange of Class R-II Certificates, but the Certificate Registrar
may require payment of a sum sufficient to cover any tax or other governmental
charge that may be imposed in connection with any transfer or exchange of Class
R-II Certificates.

                  The Depositor, the Master Servicer, the Special Servicer, the
Trustee and the Certificate Registrar and any agent of the Depositor, the Master
Servicer, the Special Servicer, the Trustee or the Certificate Registrar may
treat the Person in whose name this Certificate is registered as the owner
hereof for all purposes, and none of the Depositor, the Master Servicer, the
Special Servicer, the Trustee, the Certificate Registrar or any such agent shall
be affected by notice to the contrary.

                  The Trust Fund and the obligations created by the Agreement
shall terminate upon distribution (or provision for distribution) to the
Certificateholders of all amounts held by or on behalf of the Trustee and
required to be distributed to them pursuant to the Agreement following the
earlier to occur of (i) the final payment (or any advance with respect thereto)
or other liquidation of the last Mortgage Loan or REO Property remaining in the
Trust Fund, and

<PAGE>

(ii) the purchase by the Master Servicer, the Special Servicer or the Majority
Subordinate Certificateholder at a price determined as provided in the Agreement
of all Mortgage Loans and each REO Property remaining in the Trust Fund. The
Agreement permits, but does not require, the Master Servicer, the Special
Servicer or the Majority Subordinate Certificateholder to purchase from the
Trust Fund all Mortgage Loans and each REO Property remaining therein. The
exercise of such right will effect early retirement of the Certificates;
however, such right to purchase is subject to the aggregate Stated Principal
Balance of the Mortgage Pool at the time of purchase being less than 1% of the
aggregate Stated Principal Balance of the Mortgage Loans as of the Closing Date
specified on the face hereof.

                  The Agreement permits, with certain exceptions therein
provided, the amendment thereof and the modification of the rights and
obligations of the Depositor, the Master Servicer, the Special Servicer and the
Trustee and the rights of the Certificateholders under the Agreement at any time
by the Depositor, the Master Servicer, the Special Servicer and the Trustee with
the consent of the Holders of Certificates entitled to at least 51% of the
Voting Rights allocated to the affected Classes. The Holder of this Certificate
is not entitled to any Voting Rights. The Agreement also permits the amendment
thereof, in certain limited circumstances, including any amendment necessary to
maintain the status of the Trust Fund (or designated portions thereof) as
consisting of three separate REMICs and a grantor trust, without the consent of
the Holders of any of the Certificates.

                  Unless the certificate of authentication hereon has been
executed by the Certificate Registrar, by manual signature, this Certificate
shall not be entitled to any benefit under the Agreement or be valid for any
purpose.

                  The registered Holder hereof, by its acceptance hereof, agrees
that it will look solely to the Trust Fund (to the extent of its rights therein)
for distributions hereunder.

                  This Certificate shall be construed in accordance with the
internal laws of the State of New York applicable to agreements made and to be
performed in said State, and the obligations, rights and remedies of the Holder
hereof shall be determined in accordance with such laws.

                  IN WITNESS WHEREOF, the Certificate Registrar has caused this
Certificate to be duly executed.

N.V., KEYCORP REAL ESTATE CAPITAL MARKETS, INC. OR ANY OF THEIR RESPECTIVE
AFFILIATES. NEITHER THIS CERTIFICATE NOR THE UNDERLYING MORTGAGE LOANS ARE

<PAGE>

5.02 OF THE POOLING AND SERVICING AGREEMENT REFERRED TO HEREIN.

NO SALE OR TRANSFER OF THIS CERTIFICATE OR ANY INTEREST THEREIN SHALL BE MADE TO
ANY "EMPLOYEE BENEFIT PLAN" SUBJECT TO TITLE I OF THE EMPLOYEE RETIREMENT INCOME
SECURITY ACT OF 1974, AS AMENDED ("ERISA"), OR A "PLAN" DESCRIBED BY SECTION
4975(E)(1) OF THE CODE, THAT IS SUBJECT TO SECTION 4975 OF THE CODE, OR ANY

Certificate (as specified above) in that certain beneficial ownership interest
evidenced by all the Class Z-I Certificates in the Trust Fund created pursuant

which term includes any successor entity under the Agreement), ARCap Servicing,
Inc. (herein called the "Special Servicer", which term includes any successor
entity under the Agreement), LaSalle Bank National Association (herein called
the "Trustee", which term includes any successor entity under the Agreement),

provisions of which is set forth hereafter. To the extent not defined herein,
the capitalized terms used herein have the respective meanings assigned in the
Agreement. This Certificate is issued under and is subject to the terms,
provisions and conditions of the Agreement, to which Agreement the Holder of
this Certificate by virtue of the acceptance hereof assents and by which such
Holder is bound.

                  Pursuant to the terms of the Agreement, distributions will be
made on the 12th day of any given month, or if the 12th day is not a Business
Day, on the next succeeding Business Day (each, a "Distribution Date"). With
respect to each Distribution Date, the Determination Date is the 4th Business
Day prior to the Distribution Date (each, a "Determination Date"). Distributions
will be made commencing on the first Distribution Date specified above, to the
Person in whose name this Certificate is registered at the close of business on
the last Business Day of the month immediately preceding the month of such
distribution (the "Record Date"), in an amount equal to the product of the
Percentage Interest evidenced by this Certificate and the amount required to be

<PAGE>

Distribution Date pursuant to the Agreement. All distributions made under the
Agreement on the Class Z-I Certificates will be made by the Trustee, by wire
transfer of immediately available funds to the account of the Person entitled
thereto at a bank or other entity having appropriate facilities therefor, if
such Certificateholder shall have provided the Trustee with wiring instructions
no less than five Business Days prior to the related Record Date (which wiring
instructions may be in the form of a standing order applicable to all subsequent
distributions), or otherwise by check mailed to the address of such
Certificateholder as it appears in the Certificate Register. Notwithstanding the
foregoing, the final distribution on this Certificate will be made in like
manner, but only upon presentation and surrender of this Certificate at the
offices of the Certificate Registrar or such other location specified in the
notice to the Holder hereof of such final distribution.

                  The Certificates are limited in right of distribution to
certain collections and recoveries of Additional Interest payable on Merrill
Mortgage Loans, all as more specifically set forth herein and in the Agreement.

                  The Class Z-I Certificates are issuable in fully registered
form only without coupons in minimum denominations representing Percentage
Interests specified in the Agreement. As provided in the Agreement and subject
to certain limitations therein set forth, Class Z-I Certificates are
exchangeable for new Class Z-I Certificates in authorized denominations
evidencing the same aggregate Percentage Interest, as requested by the Holder
surrendering the same.

                  Any distribution to the Holder of this Certificate is binding
on such Holder and all future Holders of this Certificate and any Certificate
issued upon the transfer hereof or in exchange herefor or in lieu hereof whether
or not notation of such distribution is made upon this Certificate.

                  As provided in the Agreement and subject to certain
limitations therein set forth, the transfer of this Certificate is registrable
in the Certificate Register upon surrender of this Certificate for registration
of transfer at the offices of the Certificate Registrar, duly endorsed by, or
accompanied by a written instrument of transfer in the form satisfactory to the
Certificate Registrar duly executed by, the Holder hereof or his attorney duly
authorized in writing, and thereupon one or more new Class Z-I Certificates in
authorized denominations evidencing the same aggregate Percentage Interest will
be issued to the designated transferee or transferees.

                  With respect to any offer, sale, pledge or other transfer of
any Class Z-I Certificate, no such transfer of a Class Z-I Certificate shall be
made unless that transfer is made pursuant to an effective registration
statement under the Securities Act, and effective registration or qualification
under applicable state securities laws, or is made in a transaction which does
not require such registration or qualification. If such a transfer is to be made
without registration under the Securities Act (other than in connection with the
initial issuance thereof or the initial transfer thereof by the Depositor, the
Underwriters or their respective affiliates), then the Certificate Registrar
shall refuse to register such transfer unless it receives either: (i) a
certificate from the Certificateholder desiring to effect such transfer
substantially in the form attached as

<PAGE>

Exhibit E-1 to the Agreement, and a certificate from such Certificateholder's
prospective transferee substantially in the form attached as either Exhibit E-2
(which relates to sales to QIBs in reliance on Rule 144A) or Exhibit E-3 (which
relates to sales to Institutional Accredited Investors) to the Agreement; or
(ii) an Opinion of Counsel satisfactory to the Certificate Registrar to the
effect that such transfer may be made without registration under the Securities
Act (which Opinion of Counsel shall not be an expense of the Trust Fund or of
the Depositor, the Master Servicer, the Special Servicer, the Trustee or the
Certificate Registrar in their respective capacities as such), together with the
written certification(s) as to the facts surrounding such transfer from the
Certificateholder desiring to effect such transfer and/or such
Certificateholder's prospective transferee on which such Opinion of Counsel is
based. None of the Depositor, the Trustee or the Certificate Registrar is
obligated to register or qualify the Class Z-I Certificates under the Securities
Act or any other securities law or to take any action not otherwise required
under the Agreement to permit the transfer of any Class Z-I Certificate without
registration or qualification. Any Class Z-I Certificateholder desiring to
effect such a transfer shall, and by the acceptance of its Class Z-I Certificate
agrees to, indemnify the Trustee, the Certificate Registrar and the Depositor
against any liability that may result if the transfer is not so exempt or is not
made in accordance with such federal and state laws.

                  No service charge will be imposed for any registration of
transfer or exchange of Class Z-I Certificates, but the Certificate Registrar
may require payment of a sum sufficient to cover any tax or other governmental
charge that may be imposed in connection with any transfer or exchange of Class
Z-I Certificates.

                  The Depositor, the Master Servicer, the Special Servicer, the
Trustee and the Certificate Registrar and any agent of the Depositor, the Master
Servicer, the Special Servicer, the Trustee or the Certificate Registrar may
treat the Person in whose name this Certificate is registered as the owner
hereof for all purposes whatsoever and none of the Depositor, the Master
Servicer, the Special Servicer, the Trustee, the Certificate Registrar or any
such agent shall be affected by notice to the contrary.

                  The Trust Fund and the obligations created by the Agreement
shall terminate upon distribution (or provision for distribution) to the
Certificateholders of all amounts held by or on behalf of the Trustee and
required to be distributed to them pursuant to the Agreement following the
earlier to occur of (i) the final payment (or any advance with respect thereto)
or other liquidation of the last Mortgage Loan or REO Property remaining in the
Trust Fund, and (ii) the purchase by the Master Servicer, the Special Servicer
or the Majority Subordinate Certificateholder at a price determined as provided
in the Agreement of all Mortgage Loans and each REO Property remaining in the
Trust Fund. The Agreement permits, but does not require, the Master Servicer,
the Special Servicer or the Majority Subordinate Certificateholder to purchase
from the Trust Fund all Mortgage Loans and each REO Property remaining therein.
The exercise of such right will effect early retirement of the Class Z-I
Certificates; however, such right to purchase is subject to the aggregate Stated
Principal Balance of the Mortgage Pool at the time of purchase being less than
1% of the aggregate Stated Principal Balance of the Mortgage Loans as of the
Closing Date specified on the face hereof.

                  The Agreement permits, with certain exceptions therein
provided, the amendment thereof and the modification of the rights and
obligations of the Depositor, the Master Servicer, the Special Servicer and the
Trustee and the rights of the Certificateholders under the Agreement at any time
by the Depositor, the Master Servicer, the Special Servicer and the Trustee with
the consent of the Holders of Certificates entitled to at least 51% of the
Voting Rights allocated to the affected Classes. The Holder of this Certificate
is not entitled to any Voting Rights. The Agreement also permits the amendment
thereof, in certain limited circumstances, including any amendment necessary to
maintain the status of the Trust Fund (or designated portions thereof) as
consisting of three separate REMICs and a grantor trust, without the consent of
the Holders of any of the Certificates.

                  Unless the certificate of authentication hereon has been
executed by the Certificate Registrar, by manual signature, this Certificate
shall not be entitled to any benefit under the Agreement or be valid for any
purpose.

                  The registered Holder hereof, by its acceptance hereof, agrees
that it will look solely to the Trust Fund (to the extent of its rights therein)
for distributions hereunder.

                  This Certificate shall be construed in accordance with the
internal laws of the State of New York applicable to agreements made and to be
performed in said State, and the obligations, rights and remedies of the Holder
hereof shall be determined in accordance with such laws.

                  IN WITNESS WHEREOF, the Certificate Registrar has caused this
Certificate to be duly executed.

which term includes any successor entity under the Agreement), ARCap Servicing,
Inc. (herein called the "Special Servicer", which term includes any successor
entity under the Agreement), LaSalle Bank National Association (herein called

Agreement. This Certificate is issued under and is subject to the terms,
provisions and conditions of the Agreement, to which Agreement the Holder of
this Certificate by virtue of the acceptance hereof assents and by which such
Holder is bound.

                  Pursuant to the terms of the Agreement, distributions will be
made on the 12th day of any given month, or if the 12th day is not a Business
Day, on the next succeeding Business Day (each, a "Distribution Date"). With

thereto at a bank or other entity having appropriate facilities therefor, if
such Certificateholder shall have provided the Trustee with wiring instructions
no less than five Business Days prior to the related Record Date (which wiring
instructions may be in the form of a standing order applicable to all subsequent
distributions), or otherwise by check mailed to the address of such
Certificateholder as it appears in the Certificate Register. Notwithstanding the
foregoing, the final distribution on this Certificate will be made in like
manner, but only upon presentation and surrender of this Certificate at the
offices of the Certificate Registrar or such other location specified in the
notice to the Holder hereof of such final distribution.

                  The Certificates are limited in right of distribution to
certain collections and recoveries of Additional Interest payable on Merrill
Mortgage Loans, all as more specifically set forth herein and in the Agreement.

                  The Class Z-II Certificates are issuable in fully registered
form only without coupons in minimum denominations representing Percentage
Interests specified in the Agreement. As provided in the Agreement and subject
to certain limitations therein set forth, Class Z-II Certificates are
exchangeable for new Class Z-II Certificates in authorized denominations
evidencing the same aggregate Percentage Interest, as requested by the Holder
surrendering the same.

                  Any distribution to the Holder of this Certificate is binding
on such Holder and all future Holders of this Certificate and any Certificate
issued upon the transfer hereof or in exchange herefor or in lieu hereof whether
or not notation of such distribution is made upon this Certificate.

                  As provided in the Agreement and subject to certain
limitations therein set forth, the transfer of this Certificate is registrable
in the Certificate Register upon surrender of this Certificate for registration
of transfer at the offices of the Certificate Registrar, duly endorsed by, or
accompanied by a written instrument of transfer in the form satisfactory to the
Certificate Registrar duly executed by, the Holder hereof or his attorney duly
authorized in writing, and thereupon one or more new Class Z-II Certificates in
authorized denominations evidencing the same aggregate Percentage Interest will
be issued to the designated transferee or transferees.

                  With respect to any offer, sale, pledge or other transfer of
any Class Z-II Certificate, no such transfer of a Class Z-II Certificate shall
be made unless that transfer is made pursuant to an effective registration
statement under the Securities Act, and effective registration or qualification
under applicable state securities laws, or is made in a transaction which does
not require such registration or qualification. If such a transfer is to be made
without registration under the Securities Act (other than in connection with the
initial issuance thereof or the initial transfer thereof by the Depositor, the
Underwriters or their respective affiliates), then the Certificate Registrar
shall refuse to register such transfer unless it receives either: (i) a
certificate from the Certificateholder desiring to effect such transfer
substantially in the form attached as

<PAGE>

Exhibit E-1 to the Agreement, and a certificate from such Certificateholder's
prospective transferee substantially in the form attached as either Exhibit E-2
(which relates to sales to QIBs in reliance on Rule 144A) or Exhibit E-3 (which
relates to sales to Institutional Accredited Investors) to the Agreement; or
(ii) an Opinion of Counsel satisfactory to the Certificate Registrar to the
effect that such transfer may be made without registration under the Securities
Act (which Opinion of Counsel shall not be an expense of the Trust Fund or of
the Depositor, the Master Servicer, the Special Servicer, the Trustee or the
Certificate Registrar in their respective capacities as such), together with the
written certification(s) as to the facts surrounding such transfer from the
Certificateholder desiring to effect such transfer and/or such
Certificateholder's prospective transferee on which such Opinion of Counsel is
based. None of the Depositor, the Trustee or the Certificate Registrar is
obligated to register or qualify the Class Z-II Certificates under the
Securities Act or any other securities law or to take any action not otherwise
required under the Agreement to permit the transfer of any Class Z-II
Certificate without registration or qualification. Any Class Z-II
Certificateholder desiring to effect such a transfer shall, and by the
acceptance of its Class Z-II Certificate agrees to, indemnify the Trustee, the
Certificate Registrar and the Depositor against any liability that may result if
the transfer is not so exempt or is not made in accordance with such federal and
state laws.

                  No service charge will be imposed for any registration of
transfer or exchange of Class Z-II Certificates, but the Certificate Registrar
may require payment of a sum sufficient to cover any tax or other governmental
charge that may be imposed in connection with any transfer or exchange of Class
Z-II Certificates.

                  The Depositor, the Master Servicer, the Special Servicer, the
Trustee and the Certificate Registrar and any agent of the Depositor, the Master
Servicer, the Special Servicer, the Trustee or the Certificate Registrar may
treat the Person in whose name this Certificate is registered as the owner
hereof for all purposes whatsoever and none of the Depositor, the Master
Servicer, the Special Servicer, the Trustee, the Certificate Registrar or any
such agent shall be affected by notice to the contrary.

                  The Trust Fund and the obligations created by the Agreement
shall terminate upon distribution (or provision for distribution) to the
Certificateholders of all amounts held by or on behalf of the Trustee and
required to be distributed to them pursuant to the Agreement following the
earlier to occur of (i) the final payment (or any advance with respect thereto)
or other liquidation of the last Mortgage Loan or REO Property remaining in the
Trust Fund, and (ii) the purchase by the Master Servicer, the Special Servicer
or the Majority Subordinate Certificateholder at a price determined as provided
in the Agreement of all Mortgage Loans and each REO Property remaining in the
Trust Fund. The Agreement permits, but does not require, the Master Servicer,
the Special Servicer or the Majority Subordinate Certificateholder to purchase
from the Trust Fund all Mortgage Loans and each REO Property remaining therein.
The exercise of such right will effect early retirement of the Class Z-II
Certificates; however, such right to purchase is subject to the aggregate Stated
Principal Balance of the Mortgage Pool at the time of purchase being less than
1% of the aggregate Stated Principal Balance of the Mortgage Loans as of the
Closing Date specified on the face hereof.

<PAGE>

                  The Agreement permits, with certain exceptions therein
provided, the amendment thereof and the modification of the rights and
obligations of the Depositor, the Master Servicer, the Special Servicer and the
Trustee and the rights of the Certificateholders under the Agreement at any time
by the Depositor, the Master Servicer, the Special Servicer and the Trustee with
the consent of the Holders of Certificates entitled to at least 51% of the
Voting Rights allocated to the affected Classes. The Holder of this Certificate
is not entitled to any Voting Rights. The Agreement also permits the amendment
thereof, in certain limited circumstances, including any amendment necessary to
maintain the status of the Trust Fund (or designated portions thereof) as
consisting of three separate REMICs and a grantor trust, without the consent of
the Holders of any of the Certificates.

                  Unless the certificate of authentication hereon has been
executed by the Certificate Registrar, by manual signature, this Certificate
shall not be entitled to any benefit under the Agreement or be valid for any
purpose.

                  The registered Holder hereof, by its acceptance hereof, agrees
that it will look solely to the Trust Fund (to the extent of its rights therein)
for distributions hereunder.

                  This Certificate shall be construed in accordance with the
internal laws of the State of New York applicable to agreements made and to be
performed in said State, and the obligations, rights and remedies of the Holder
hereof shall be determined in accordance with such laws.

                  IN WITNESS WHEREOF, the Certificate Registrar has caused this
Certificate to be duly executed.

                           The term "securities" as used herein does not include

                           basis by the Transferee, the Transferee used the cost
                           of such securities to the Transferee, unless the
                           Transferee reports its securities holdings in its
                           financial statements on the basis of their market
                           value, and no current information with respect to the

                           those securities has been published, in which case
                           the securities were valued at market.

                           Further, in determining such aggregate amount, the
                           Transferee may have included securities owned by
                           subsidiaries of the Transferee, but only if such
                           subsidiaries are consolidated with the Transferee in
                           its financial statements prepared in accordance with
                           generally accepted accounting principles and if the
                           investments of such subsidiaries are managed under
                           the Transferee's direction. However, such securities
                           were not included if the Transferee is a
                           majority-owned, consolidated subsidiary of another
                           enterprise and the Transferee is not itself a
                           reporting company under the Securities Exchange Act
                           of 1934.

     3. The Transferee acknowledges that it is familiar with Rule 144A and
understands that the parties to which this certification is being made are
relying and will continue to rely on the statements made herein because one or
more sales to the Transferee may be in reliance on Rule 144A.

                                      Will the Transferee be purchasing the
                                      Transferred Certificate only for the
           ---------      ----------  Transferee's own account?
              Yes            No

     4. If the answer to the foregoing question is "no", then in each case where
the Transferee is purchasing for an account other than its own, such account
belongs to a third party that is itself a "qualified institutional buyer" within
the meaning of Rule 144A, and the "qualified institutional buyer" status of such
third party has been established by the Transferee through one or more of the
appropriate methods contemplated by Rule 144A.

     5. The Transferee will notify each of the parties to which this
certification is made of any changes in the information and conclusions herein.
Until such notice is given, the Transferee's purchase of the Transferred
Certificate will constitute a reaffirmation of this certification as of the date
of such purchase. In addition, if the Transferee is a bank or savings and loan
as provided above, the Transferee agrees that it will furnish to such parties
any updated annual financial statements that become available on or before the
date of such purchase, promptly after they become available.

buyer" within the meaning of Rule 144A, and the "qualified institutional buyer"
status of such third party has been established by the Transferee through one or
more of the appropriate methods contemplated by Rule 144A.

Re:      Merrill Lynch Mortgage Trust 2003-KEY1,
         Commercial Mortgage Pass-Through Certificates,
         Series 2003-KEY1 (the "Certificates")

Ladies and Gentlemen:

                  This letter is delivered to you in connection with the
transfer by      (the "Transferor") to      (the "Transferee") of a Certificate
(the "Transferred Certificate") having an initial [principal balance] [notional
amount] as of November 20, 2003 (the "Closing Date") of $      evidencing a ___%
percentage interest in the Class to which it belongs. The Certificates were
issued pursuant to the Pooling and Servicing Agreement (the "Pooling and
Servicing Agreement"), dated as of November 1, 2003, among Merrill Lynch
Mortgage Investors, Inc., as depositor (the "Depositor"), KeyCorp Real Estate
Capital Markets, Inc., as master servicer, ARCap Servicing, Inc., as special
servicer, LaSalle Bank National Association, as trustee, and ABN AMRO Bank N.V.,
as fiscal agent. All terms used herein and not otherwise defined shall have the
meanings set forth in the Pooling and Servicing Agreement. The Transferee hereby
certifies, represents and warrants to you, as Certificate Registrar, that:

     1. The Transferee is not purchasing a Class R-LR, Class R-I or Class R-II
Certificate.

     2. The Transferee is acquiring the Transferred Certificate for its own
account for investment and not with a view to or for sale or transfer in
connection with any distribution thereof, in whole or in part, in any manner
which would violate the Securities Act of 1933, as amended (the "Securities
Act"), or any applicable state securities laws.

     3. The Transferee understands that (a) the Certificates have not been and
will not be registered under the Securities Act or registered or qualified under
any applicable state securities laws, (b) neither the Depositor nor the Trustee
or the Certificate Registrar is obligated so to register or qualify the
Certificates and (c) the Certificates may not be resold or transferred unless
they are (i) registered pursuant to the Securities Act and registered or
qualified pursuant to any applicable state securities laws or (ii) sold or
transferred in transactions which are exempt from

                                     E-3-1

<PAGE>

such registration and qualification and the Certificate Registrar has received
either (A) certifications from both the transferor and the transferee
(substantially in the forms attached to the Pooling and Servicing Agreement)
setting forth the facts surrounding the transfer or (B) an opinion of counsel
satisfactory to the Certificate Registrar with respect to the availability of
such exemption (which Opinion of Counsel shall not be an expense of the Trust
Fund or of the Depositor, the Master Servicer, the Special Servicer, the Trustee
or the Certificate Registrar in their respective capacities as such), together
with copies of the certification(s) from the Transferor and/or Transferee
setting forth the facts surrounding the transfer upon which such opinion is
based. Any holder of a Certificate desiring to effect such a transfer shall, and
upon acquisition of such Certificate shall be deemed to have agreed to,
indemnify the Trustee, the Certificate Registrar and the Depositor against any
liability that may result if the transfer is not so exempt or is not made in
accordance with such federal and state laws.

     4. The Transferee understands that it may not sell or otherwise transfer
any portion of its interest in the Transferred Certificate except in compliance
with the provisions of Section 5.02 of the Pooling and Servicing Agreement,

          1. That [he] [she] is a [Title of Officer] of [Name of Transferee]

     [REMIC II], to fail to qualify as a REMIC, or any Person having an
     Ownership Interest in any Class of Certificates, other than such Person,

     The terms "United States", "State" and "international organization" shall
     have the meanings set forth in Section 7701 of the Code or successor
     provisions.

     A "Non-United States Person" is any Person other than a United States
     Person. A "United States Person" is a citizen or resident of the United

     corporation or partnership for federal income tax purposes) created or
     organized in, or under the laws of the United States, any State or the

     Regulations are adopted that provide otherwise, an estate whose income is
     includable in gross income for United States federal tax income purposes
     regardless of its source, or a trust if a court within the United States is
     able to exercise primary supervision over the administration of the trust
     and one or more United States Persons have the authority to control all
     substantial decisions of the trust, all within the meaning of Section
     7701(a)(30) of the Code.

          3. That the Transferee is aware (i) of the tax that would be imposed
     on transfers of the Class [R-LR] [R-I] [R-II] Certificates to disqualified
     organizations under the Code that applies to all transfers of the Class
     [R-LR] [R-I] [R-II] Certificates after March 31, 1988; (ii) that such tax
     would be on the transferor, or, if such transfer is through an agent (which
     person includes a broker, nominee or middleman) for a disqualified
     organization Transferee, on the agent; (iii) that the person otherwise
     liable for the tax shall be relieved of liability for the tax if the
     transferee furnishes to such person an affidavit that the transferee is not
     a disqualified organization and, at the time of transfer, such person does
     not have actual knowledge that the affidavit is false; and (iv) that the
     Class [R-LR] [R-I] [R-II] Certificates may be "noneconomic residual
     interests" within the meaning of Treasury regulation section 1.860E-l(c)(2)
     and that the transferor of a "noneconomic residual interest" will remain
     liable for any taxes due with respect to the income on such residual
     interest, unless no significant purpose of the transfer is to enable the
     transferor to impede the assessment or collection of tax.

          4. That the Transferee is aware of the tax imposed on a "pass-through
     entity" holding the Class [R-LR] [R-I] [R-II] Certificates if at any time
     during the taxable year of the pass-through entity a non-Permitted
     Transferee is the record holder of an interest in such entity. For this
     purpose, a "pass through entity" includes a regulated investment company, a
     real estate investment trust or common trust fund, a partnership, trust or
     estate, and certain cooperatives.

          5. That the Transferee is aware that the Certificate Registrar will
     not register the transfer of any Class [R-LR] [R-I] [R-II] Certificate
     unless the transferee, or the transferee's agent, delivers to the Trustee,
     among other things, an affidavit in substantially the same form as this
     affidavit. The Transferee expressly agrees that it will not consummate any
     such transfer if it knows or believes that any of the representations
     contained in such affidavit and agreement are false.

                                     G-1-2

<PAGE>

          6. That the Transferee consents to any additional restrictions or
     arrangements that shall be deemed necessary upon advice of counsel to
     constitute a reasonable arrangement to ensure that the Class [R-LR] [R-I]
     [R-II] Certificates will only be owned, directly or indirectly, by
     Permitted Transferees.

          7. That the Transferee's taxpayer identification number is _________.

          8. That the Transferee has reviewed the restrictions set forth on the
     face of the Class [R-LR] [R-I] [R-II] Certificates and the provisions of
     Section 5.02 of the Pooling and Servicing Agreement under which the Class
     [R-LR] [R-I] [R-II] Certificates were issued (and, in particular, the
     Transferee is aware that such Section authorizes the Trustee to deliver
     payments to a person other than the Transferee and negotiate a mandatory
     sale by the Trustee in the event that the Transferee holds such Certificate
     in violation of Section 5.02); and that the Transferee expressly agrees to
     be bound by and to comply with such restrictions and provisions.

          9. That the Transferee is not acquiring and will not transfer the
     Class [R-LR] [R-I] [R-II] Certificates in order to impede the assessment or
     collection of any tax.

          10. That the Transferee has historically paid its debts as they have
     come due, intends to continue to pay its debts as they come due in the
     future, and anticipates that it will, so long as it holds any of the Class
     [R-LR] [R-I] [R-II] Certificates, have sufficient assets to pay any taxes
     owed by the holder of such Class [R-LR] [R-I] [R-II] Certificates.

          11. That the Transferee has no present knowledge that it may become
     insolvent or subject to a bankruptcy proceeding for so long as it holds any
     of the Class [R-LR] [R-I] [R-II] Certificates.

          12. That the Transferee has no present knowledge or expectation that
     it will be unable to pay any United States taxes owed by it so long as any
     of the Certificates remain outstanding. In this regard, the Transferee
     hereby represents to and for the benefit of the Person from whom it
     acquired the Class [R-LR] [R-I] [R-II] Certificates that the Transferee
     intends to pay taxes associated with holding the Class [R-LR] [R-I] [R-II]
     Certificates as they become due, fully understanding that it may incur tax
     liabilities in excess of any cash flows generated by the Class [R-LR] [R-I]
     [R-II] Certificates.

          13. That the Transferee is not acquiring the Class [R-LR] [R-I]
     [R-II] Certificates with the intent to transfer any of the Class [R-LR]
     [R-I] [R-II] Certificates to any person or entity that will not have
     sufficient assets to pay any taxes owed by the holder of such Class [R-LR]
     [R-I] [R-II] Certificates, or that may become insolvent or subject to a
     bankruptcy proceeding, for so long as the Class [R-LR] [R-I] [R-II]
     Certificates remain outstanding.

          14. That the Transferee will, in connection with any transfer that it
     makes of the Class [R-LR] [R-I] [R-II] Certificates, obtain from its
     transferee the representations required by Section 5.02(d) of the Pooling
     and Servicing Agreement under which the Class [R-LR] [R-I] [R-II]
     Certificates were issued and will not consummate any such

                                     G-1-3

<PAGE>

     transfer if it knows, or knows facts that should lead it to believe, that
     any such representations are false.

          15. That the Transferee will, in connection with any transfer that it
     makes of any Class [R-LR] [R-I] [R-II] Certificate, deliver to the
     Certificate Registrar an affidavit, which represents and warrants that it
     is not transferring such Class [R-LR] [R-I] [R-II] Certificate to impede
     the assessment or collection of any tax and that it has no actual knowledge
     that the proposed transferee: (i) has insufficient assets to pay any taxes
     owed by such transferee as holder of such Class [R-LR] [R-I] [R-II]
     Certificate; (ii) may become insolvent or subject to a bankruptcy
     proceeding, for so long as the Class [R-LR] [R-I] [R-II] Certificates
     remain outstanding; and (iii) is not a "Permitted Transferee".

          16. That, if a "tax matters person" is required to be designated with
     respect to [the 77 West Wacker Drive Loan REMIC] [REMIC I] [REMIC II], the
     Transferee agrees to act as "tax matters person" and to perform the
     functions of "tax matters person" of [the 77 West Wacker Drive Loan REMIC]
     [REMIC I] [REMIC II] pursuant to Section [ ] of the Pooling and Servicing
     Agreement, and, in such event, agrees to the irrevocable designation of the
     Trustee as the Transferee's agent in performing the function of "tax
     matters person."

          17. That the Transferee will not cause income from the Class [R-LR]
     [R-I] [R-II] Certificate to be attributable to a foreign permanent
     establishment or fixed base, within the meaning of an applicable income tax
     treaty, of the Transferee or any other U.S. Person.

          18. Check one of the following:

          ___ That the present value of the anticipated tax liabilities
     associated with holding the Class [R-LR] [R-I] [R-II] Certificate does not
     exceed the sum of:

          (i)  the present value of any consideration given to the Transferee to
               acquire such Class [R-LR] [R-I] [R-II] Certificate;

          (ii) the present value of the expected future distributions on such
               Class [R-LR] [R-I] [R-II] Certificate; and

          (iii) the present value of the anticipated tax savings associated with
               holding such Class [R-LR] [R-I] [R-II] Certificate as the related
               REMIC generates losses.

                  For purposes of this calculation, (i) the Transferee is
assumed to pay tax at the highest rate currently specified in Section 11(b) of
the Code (but the tax rate in Section 55(b)(1)(B) of the Code may be used in
lieu of the highest rate specified in Section 11(b) of the Code if the
Transferee has been subject to the alternative minimum tax under Section 55 of
the Code in the preceding two years and will compute its taxable income in the
current taxable year using the alternative minimum tax rate) and (ii) present
values are computed using a discount

                                     G-1-4

<PAGE>

rate equal to the short-term Federal rate prescribed by Section 1274(d) of the
Code for the month of the transfer and the compounding period used by the
Transferee.

                  ___ That the transfer of the Class [R-LR] [R-I] [R-II]
Certificate complies with U.S. Treasury Regulations Sections 1.860E-1(c)(5) and
(6) and, accordingly,

                  (i)  the Transferee is an "eligible corporation", as defined
                       in U.S. Treasury Regulations Sections
                       1.860E-1(c)(6)(i), as to which income from Class [R-LR]
                       [R-I] [R-II] Certificate will only be taxed in the
                       United States;

                  (ii) at the time of the transfer, and at the close of the
                       Transferee's two fiscal years preceding the year of the
                       transfer, the Transferee had gross assets for financial
                       reporting purposes (excluding any obligation of a
                       person related to the Transferee within the meaning of
                       U.S. Treasury Regulation Section 1.860E-1(c)(6)(ii)) in
                       excess of $100 million and net assets in excess of $ 10
                       million; and

                  (iii)the Transferee will transfer the Class [R-LR] [R-I]
                       [R-II] Certificate only to another "eligible
                       corporation", as defined in U.S. Treasury Regulations
                       Section 1.860E-1(c)(6)(i), in a transaction that
                       satisfies the requirements of U.S. Treasury Regulations
                       Sections 1.860G-1(c)(4)(i), (ii) and (iii) and
                       1.860E-1(c)(5).

                  __     None of the above.

             Commercial Mortgage Pass-Through Certificates,
             Series 2003-KEY1, Class [R-LR], [R-I] [R-II], evidencing a _____%

Dear Sirs:

                  This letter is delivered to you in connection with the
transfer by      (the "Transferor") to      (the "Transferee") of the captioned
Class [R-LR] [R-I] [R-II] Certificates (the "Class [R-LR] [R-I] [R-II]
Certificates"), pursuant to Section 5.02 of the Pooling and Servicing Agreement
(the "Pooling and Servicing Agreement"), dated as of November 1, 2003, among
Merrill Lynch Mortgage Investors, Inc., as depositor, KeyCorp Real Estate
Capital Markets, Inc., as master servicer, ARCap Servicing, Inc., as special
servicer, LaSalle Bank National Association, as trustee, and ABN AMRO Bank N.V.,
as fiscal agent. All terms used herein and not otherwise defined shall have the
meanings set forth in the Pooling and Servicing Agreement. The Transferor hereby
represents and warrants to you, as Certificate Registrar, that:

               1. No purpose of the Transferor relating to the transfer of the
          Class [R-LR] [R-I] [R-II] Certificates by the Transferor to the
          Transferee is or will be to impede the assessment or collection of any
          tax.

               2. The Transferor understands that the Transferee has delivered
          to you a Transfer Affidavit and Agreement in the form attached to the
          Pooling and Servicing Agreement as Exhibit G-1. The Transferor does
          not know or believe that any representation contained therein is
          false.

               3. The Transferor at the time of this transfer either (i) has
          conducted a reasonable investigation of the financial condition of the
          Transferee as contemplated by Treasury regulation section
          1.860E-1(c)(4)(i) and, as a result of that investigation, the
          Transferor has determined that the Transferee has historically paid
          its debts as they

                                     G-2-1

<PAGE>

          became due and has found no significant evidence to indicate that the
          Transferee will not continue to pay its debts as they become due in
          the future.

               4. The Transferor understands that the transfer of the Class
          [R-LR] [R-I] [R-II] Certificates may not be respected for United
          States income tax purposes (and the Transferor may continue to be
          liable for United States income taxes associated therewith) unless the
          tests described above in Paragraph 3(i) or 3(ii) have been met as to
          any transfer.

                                      Very truly yours,

                  Loan (the "Mortgage Loan") heretofore secured by real property
                  known as _______.

         Capitalized terms used but not defined herein have the meanings
assigned to such terms in the Pooling and Servicing Agreement.

         THE STATEMENTS SET FORTH BELOW ARE MADE (A) TO THE BEST KNOWLEDGE OF
THE UNDERSIGNED BASED UPON DUE DILIGENCE CONSISTENT WITH THE SERVICING STANDARD
SPECIFIED IN THE POOLING AND SERVICING AGREEMENT (THE "SERVICING STANDARD"), AND
(B) WITHOUT INTENDING TO WARRANT THE ACCURACY THEREOF OR UNDERTAKE ANY DUTY OR
STANDARD OF CARE GREATER THAN THE DUTIES OF THE MASTER SERVICER UNDER THE
POOLING AND SERVICING AGREEMENT AND THE SERVICING STANDARD.

         We hereby notify you and confirm that each of the following is true,
subject to those exceptions, if any, set forth on EXHIBIT A hereto, which
exceptions the Master Servicer has determined, consistent with the Servicing
Standard, will have no material adverse effect on the Mortgage Loan or the
defeasance transaction:

          1.   The Mortgagor has consummated a defeasance of the Mortgage Loan
               of the type checked below:

               ____  a full defeasance of the entire outstanding principal
                     balance ($___________) of the Mortgage Loan; or

               ____  a partial defeasance of a portion ($__________) of the
                     Mortgage Loan that represents ___% of the entire principal
                     balance of the Mortgage Loan ($________);

          2.   The defeasance was consummated on __________, 20__.

                                     K-1-1

<PAGE>

          3.   The defeasance was completed in all material respects in
               accordance with the conditions for defeasance specified in the
               Mortgage Loan Documents and in accordance with the Servicing
               Standard.

          4.   The defeasance collateral consists only of one or more of the
               following: (i) direct debt obligations of the U.S. Treasury, (ii)
               direct debt obligations of the Federal National Mortgage
               Association, (iii) direct debt obligations of the Federal Home
               Loan Mortgage Corporation, or (iv) interest-only direct debt
               obligations of the Resolution Funding Corporation. Such
               defeasance collateral consists of securities that (i) if they
               include a principal obligation, the principal due at maturity
               cannot vary or change, (ii) provide for interest at a fixed rate
               and (iii) are not subject to prepayment, call or early
               redemption.

          5.   After the defeasance, the defeasance collateral will be owned by
               an entity (the "Defeasance Obligor") that: (i) is the original
               Borrower, (ii) is a Single-Purpose Entity (as defined in the S&P
               Criteria), (iii) is subject to restrictions in its organizational
               documents substantially similar to those contained in the
               organizational documents of the original Borrower with respect to
               bankruptcy remoteness and single purpose, (iv) has been
               designated as the Defeasance Obligor by the originator of the
               Mortgage Loan pursuant to the terms of the Mortgage Loan
               Documents, or (v) has delivered a letter from Standard & Poor's
               confirming that the organizational documents of such Defeasance
               Obligor were previously approved by Standard & Poor's. The
               Defeasance Obligor owns no assets other than defeasance
               collateral and (only in the case of the original Borrower) real
               property securing one or more Mortgage Loans included in the pool
               under the Pooling and Servicing Agreement (the "Pool").

          6.   If such Defeasance Obligor (together with its affiliates) holds
               more than one defeased loan, it does not (together with its
               affiliates) hold defeased loans aggregating more than $20 Million
               or more than five percent (5%) of the aggregate certificate
               balance of the Certificates as of the date of the most recent
               Paying Agent's Monthly Certificateholder Report received by
               Servicer (the "Current Report").

          7.   The defeasance documents require that the defeasance collateral
               be credited to an eligible account (as defined in the S&P
               Criteria) that must be maintained as a securities account by a
               securities intermediary that is at all times an Eligible
               Institution (as defined in the S&P Criteria). The securities
               intermediary may reinvest proceeds of the defeasance collateral
               only in Permitted Investments (as defined in the Pooling and
               Servicing Agreement).

          8.   The securities intermediary is obligated to pay from the proceeds
               of the defeasance collateral, directly to the Servicer's
               collection account, all scheduled payments on the Mortgage Loan
               or, in a partial defeasance, not less than 125% of the portion of
               such scheduled payments attributed to the allocated loan amount
               for the real property defeased (the "Scheduled Payments").

          9.   The Servicer received written confirmation from an independent
               certified public accountant stating that (i) revenues from the
               defeasance collateral (without taking into account any earnings
               on reinvestment of such revenues) will be sufficient to timely
               pay each of the Scheduled Payments including the payment in full
               of the Mortgage Loan (or the allocated portion thereof in
               connection with a partial defeasance) on its Maturity Date (or,
               in the case of an ARD Loan, on its Anticipated Repayment Date),
               (ii) the revenues received in any month from the defeasance
               collateral will be applied to make Scheduled

                                     K-1-2

<PAGE>

               Payments within four (4) months after the date of receipt, (iii)
               the defeasance collateral is not subject to prepayment, call or
               early redemption, and (iv) interest income from the defeasance
               collateral to the Defeasance Obligor in any tax year will not
               exceed such Defeasance Obligor's interest expense for the
               Mortgage Loan (or the allocated portion thereof in a partial
               defeasance) for such year, other than in the year in which the
               Maturity Date or Anticipated Repayment Date will occur, when
               interest income will exceed interest expense.

          10.  The Servicer received opinions of counsel that, subject to
               customary qualifications and exceptions, (i) the defeasance will
               not cause the Trust to fail to qualify as a REMIC for purpose of
               the Internal Revenue Code, (ii) the agreements executed by the
               Mortgagor and the Defeasance Obligor in connection with the
               defeasance are enforceable against them in accordance with their
               terms, and (iii) the Trustee will have a perfected, first
               priority security interest in the defeasance collateral.

          11.  The agreements executed in connection with the defeasance (i)
               prohibit subordinate liens against the defeasance collateral,
               (ii) provide for payment from sources other than the defeasance
               collateral of all fees and expenses of the securities
               intermediary for administering the defeasance and the securities
               account and all fees and expenses of maintaining the existence of
               the Defeasance Obligor, (iii) permit release of surplus
               defeasance collateral and earnings on reinvestment to the
               Defeasance Obligor only after the Mortgage Loan has been paid in
               full, (iv) include representations and/or covenants of the
               Mortgagor and/or securities intermediary substantially as set
               forth on EXHIBIT B hereto, (v) provide for survival of such
               representations; and (vi) do not permit waiver of such
               representations and covenants.

          12.  The outstanding principal balance of the Mortgage Loan
               immediately before the defeasance was less than $20,000,000 and
               less than 5% of the aggregate certificate balance of the
               Certificates as of the date of the current Report. The Mortgage
               Loan is not one of the ten (10) largest loans in the pool.

          13.  Copies of all material agreements, instruments, organizational
               documents, opinions of counsel, accountant's report and other
               items delivered in connection with the defeasance will be
               provided to you upon request.

          14.  The individual executing this notice is an authorized officer or
               a servicing officer of the Servicer.

         IN WITNESS WHEREOF, the Master Servicer has caused this notice to be
executed as of the date captioned above.

         GENERAL:

         1. [The defeasance agreements] create a valid and continuing security
interest (as defined in the applicable UCC) in the [Collateral, Securities
Account and Deposit Account] in favor of the [Secured Party], which security
interest is prior to all other [Liens], and is enforceable as such as against
creditors of and purchasers from [Debtor].

                  Note that "Collateral" means securities, permitted investments
                  and other assets credited to securities accounts.

         2. The [Deposit Account], constitutes a "deposit account" within the
meaning of the applicable UCC.

         3. All of the [Collateral] has been and will have been credited to a
[Securities Account]. The securities intermediary for the [Securities Account]
has agreed to treat all assets credited to the [Securities Account] as
"financial assets" within the meaning of the UCC.

         CREATION:

         4. [Debtor] owns and has good and marketable title to the [Collateral,
Securities Account and Deposit Account] free and clear of any [Lien], claim or

[Securities Account] or directing disposition of the funds in the [Deposit
Account] without further consent by the [Debtor].

         8. [Debtor] has taken all steps necessary to cause the securities
intermediary to identify in its records the [Secured Party] as the person having

pursuant to this Agreement, [Debtor] has not pledged, assigned, sold, granted a
security interest in, or otherwise conveyed any of the [Collateral, Securities
Account and Deposit Account]. [Debtor] has not authorized the filing of and is

consented to the securities intermediary of any [Securities Account] or the
account bank of any [Deposit Account] to comply with entitlement orders or
instructions of any person other than the [Secured Party].

year [___] (the "Annual Report"), and all reports on Form 8-K containing
distribution or servicing reports under the pooling and servicing agreement
dated as of November 1, 2003 and related to the captioned commercial mortgage
pass-through certificates (the "Pooling and Servicing Agreement") filed in
respect of periods included in the year covered by the Annual Report
(collectively with the Annual Report, the "Reports"), of the Trust;

         2.       Based on my knowledge, the information in the Reports, taken
as a whole, does not contain any untrue statement of a material fact or omit to
state a material fact necessary to make the statements made, in light of the
circumstances under which such statements were made, not misleading as of the
last day of the period covered by the Annual Report;

         3.       Based on my knowledge, the distribution or servicing
information required to be provided to the Trustee by the Master Servicer under
the Pooling and Servicing Agreement for inclusion in these reports is included
in the Reports;

         4.       Based on my knowledge and upon the annual compliance statement
included in the Annual Report and required to be delivered to the Trustee in
accordance with the terms of the Pooling and Servicing Agreement, and except as
disclosed in the Reports, the Master Servicer has fulfilled its obligations
under the Pooling and Servicing Agreement; and

         5.       The Reports disclose all significant deficiencies relating to
the compliance of the Master Servicer with the minimum servicing standards based
upon the report provided by an independent public accountant, after conducting a
review in compliance with the Uniform Single Attestation Program for Mortgage
Bankers or similar procedure, as set forth in the Pooling and Servicing
Agreement, that is included in the Reports.

         In giving the certifications set forth above, I have reasonably relied
on information provided to me by the following unaffiliated parties: KeyCorp
Real Estate Capital Markets, Inc., as Master Servicer, ARCap Servicing, Inc., as
Special Servicer, and LaSalle Bank National Association, as Trustee.

                         UNITED FINANCIAL MORTGAGE CORP.

                                     WARRANT

                  116,690 SHARES OF COMMON STOCK, NO PAR VALUE

                               DECEMBER ____, 2003

         This WARRANT (this "WARRANT") of United Financial Mortgage Corp., a
corporation duly organized and validly existing under the laws of the State of
Illinois (the "COMPANY"), is being issued pursuant to that certain Underwriting
Agreement, dated as of December ___, 2003, by and between the Company and Maxim
Group LLC relating to a firm commitment public offering (the "OFFERING") of
1,667,000 shares of common stock, no par value, of the Company (the "COMMON
STOCK"), underwritten by Maxim Group LLC.

         FOR VALUE RECEIVED, the Company hereby grants to Maxim Partners LLC and
its permitted successors and assigns (collectively the "HOLDER") the right to
purchase from the Company up to ONE HUNDRED SIXTEEN THOUSAND SIX HUNDRED NINETY
(116,690) shares of Common Stock (such shares underlying this Warrant, the
"WARRANT SHARES"), at a purchase price per share equal to $____ (the "EXERCISE
PRICE"), subject to the terms, conditions and adjustments set forth below in
this Warrant.

         1. Vesting of Warrant. This Warrant shall vest and become exercisable
on the first anniversary of the Base Date (the "VESTING DATE"). For purposes of
this Warrant, the "Base Date" shall mean December ____, 2003.

         2. Expiration of Warrant. This Warrant shall expire on the three (3)
year anniversary of the Vesting Date (the "EXPIRATION DATE").

         3. Exercise of Warrant. This Warrant shall be exercisable pursuant to
the terms of this Section 3.
<PAGE>
                  3.1 Manner of Exercise.

                  (a) This Warrant may only be exercised by the Holder hereof on
or after the Vesting Date and on or prior to the Expiration Date, in accordance
with the terms and conditions hereof, in whole or in part (but not as to
fractional shares) with respect to any portion of this Warrant, in minimum
increments of 10,000 shares (or, if smaller, the total number of shares
underlying this Warrant), during the Company's normal business hours on any day
other than a Saturday or a Sunday or a day on which commercial banking
institutions in Chicago, Illinois or New York, New York are authorized by law to
be closed (a "BUSINESS DAY"), by surrender of this Warrant to the Company at its
office maintained pursuant to Section 10.2(a) hereof, accompanied by a written
exercise notice in the form attached as Exhibit A to this Warrant (or a
reasonable facsimile thereof) duly executed by the Holder, together with the
payment of the Exercise Price. Upon surrender of this Warrant, the Company shall
cancel this Warrant document and shall, in the event of partial exercise,
replace it with a new Warrant document in accordance with Section 3.3

                  (b) Except as provided for below, the Warrant must be
accompanied by payment in full of the aggregate Exercise Price in cash by wire
transfer in immediately available funds for the number of Warrant Shares being
purchased. The aggregate Exercise Price may, however, also be paid in full or in
part at the election of the Holder: (i) in the form of Common Stock owned by the
Holder (based on the Fair Market Value (as defined below) of such Common Stock
on the date of exercise), (ii) in the form of Warrant Shares withheld by the
Company from the Warrant Shares otherwise to be received upon exercise of this
Warrant having an aggregate Fair Market Value on the date of exercise equal to
the aggregate Exercise Price of the Warrant, or (iii) by a combination of the
foregoing, provided that the combined value of all cash and the Fair Market
Value of any shares surrendered to the Company is at least equal to such
aggregate Exercise Price.

                  (c) For purposes of this Warrant, the term "FAIR MARKET VALUE"
means the average closing price for the ten (10) trading days immediately
preceding the applicable date of publicly-traded shares of the Common Stock on
the principal securities exchange or market on which shares of Common Stock are
listed or quoted, if the shares of Common Stock are so listed or quoted or, if
not so listed or quoted, as determined by the Company in good faith and in a
reasonable manner, based on the information available to it.

                  3.2 When Exercise Effective. Each exercise of this Warrant
shall be deemed to have been effected immediately prior to the close of business
on the Business Day on which this Warrant shall have been duly surrendered to
the Company as provided in Sections 3.1 and 12 hereof, and, at such time, the
Holder in whose name any certificate or certificates for Warrant Shares shall be
issuable upon exercise as provided in Section 3.3 hereof shall be deemed to have
become the holder or holders of record thereof.

                  3.3 Delivery of Common Stock Certificates and New Warrant. As
soon as reasonably practicable after each exercise of this Warrant, in whole or
in part, and in any event within five (5) Business Days thereafter, the Company,
at its expense (including the payment by it of any applicable issue taxes), will
cause to be issued in the name of and delivered to the

                                       2
<PAGE>
Holder hereof or, subject to Sections 9 and 10 hereof, as the Holder (upon
payment by the Holder of any applicable transfer taxes) may direct:

                  (a) a certificate or certificates (with appropriate
restrictive legends, as applicable) for the number of duly authorized, validly
issued, fully paid and nonassessable Warrant Shares to which the Holder shall be
entitled upon exercise; and

                  (b) in case exercise is in part only, a new Warrant document
of like tenor, dated the date hereof and calling in the aggregate on the face
thereof for the number of Warrant Shares on the face of this Warrant minus the
number of Warrant Shares designated by the Holder upon exercise as provided in
Section 3.1 hereof (without giving effect to any adjustment thereof).

         4. Certain Adjustments. For so long as this Warrant is outstanding:

                  4.1 Mergers or Consolidations. If at any time after the date
hereof there shall be a capital reorganization (other than a combination or
subdivision of Warrant Shares otherwise provided for herein) resulting in a
reclassification to or change in the terms of securities issuable upon exercise
of this Warrant (a "REORGANIZATION"), or a merger or consolidation of the
Company with another corporation, association, partnership, organization,
business, individual, government or political subdivision thereof or a
governmental agency (a "PERSON" or the "PERSONS") (other than a merger with
another Person in which the Company is a continuing corporation and which does
not result in any reclassification or change in the terms of securities issuable
upon exercise of this Warrant or a merger effected exclusively for the purpose
of changing the domicile of the Company) (a "MERGER"), then, as a part of such
Reorganization or Merger, lawful provision and adjustment shall be made so that
the Holder shall thereafter be entitled to receive, upon exercise of this
Warrant, the number of shares of stock or any other equity or debt securities or
property that may be issued by the Company in addition thereto or in
substitution for the Warrant Shares issuable upon the exercise hereof ("OTHER
SECURITIES") resulting from such Reorganization or Merger, to which a holder of
the Common Stock deliverable upon exercise of this Warrant would have been
entitled under the provisions of the agreement in such Reorganization or Merger
if this Warrant had been exercised immediately before that Reorganization or
Merger. In any such case, appropriate adjustment shall be made in the
application of the provisions of this Warrant with respect to the rights and
interests of the Holder after the Reorganization or Merger to the end that the
provisions of this Warrant (including adjustment of the Exercise Price then in
effect and the number of Warrant Shares) shall be applicable after that event,
as near as reasonably may be, in relation to any Other Securities deliverable
after that event upon exercise of this Warrant.

                  4.2 Splits and Subdivisions; Dividends. In the event the
Company should at any time or from time to time effectuate a split or
subdivision of the outstanding shares of Common Stock or pay a dividend in or
make a distribution, payable in additional shares of Common Stock or other
securities or rights convertible into, or entitling the holder thereof to
receive directly or indirectly, additional shares of Common Stock (hereinafter
referred to as the "COMMON STOCK EQUIVALENTS") without payment of any
consideration by such holder for the additional shares of Common Stock or Common
Stock Equivalents (including the additional shares of Common Stock issuable upon
conversion or exercise thereof) except as otherwise

                                       3
<PAGE>
provided for in this Section 4 (and excluding, for the avoidance of doubt, cash
dividends or distributions to the holders of Common Stock, paid out of current
or retained earnings and declared by the Company's board of directors), then, as
of the applicable record date (or the date of such distribution, split or
subdivision if no record date is fixed), the per share Exercise Price shall be
appropriately decreased and the number of Warrant Shares shall be appropriately
increased in proportion to such increase (or potential increase) of outstanding
shares; provided, however, that no adjustment shall be made in the event the
spilt, subdivision, dividend or distribution is not effectuated.

                  4.3 Combination of Shares. If the number of shares of Common
Stock outstanding at any time after the date hereof is decreased by a
combination of the outstanding shares of Common Stock except as otherwise
provided for in this Section 4, the per share Exercise Price shall be
appropriately increased and the number of shares of Warrant Shares shall be
appropriately decreased in proportion to such decrease in outstanding shares.

                  4.4 Adjustments for Other Distributions. In the event the
Company shall declare a distribution payable in securities of other persons,
evidences of indebtedness issued by the Company or other persons, assets
(excluding cash dividends or distributions to the holders of Common Stock, paid
out of current or retained earnings and declared by the Company's board of
directors) or options or rights not referred to in Sections 4.1, 4.2 or 4.3,
then, in each such case for the purpose of this Section 4.4, upon exercise of
this Warrant, the Holder shall be entitled to a proportionate share of any such
distribution as though the Holder was the actual record holder of the number of
Warrant Shares as of the record date fixed for the determination of the holders
of Common Stock of the Company entitled to receive such distribution.

         5. No Impairment.

                  5.1 The Company will not, by amendment of its articles of
incorporation or by-laws or through any consolidation, merger, reorganization,
transfer of assets, dissolution, issue or sale of securities or any other
voluntary action, avoid or seek to avoid the observance or performance of any of
the terms of this Warrant, but will at all times in good faith assist in the
carrying out of all of the terms and in the taking of all actions necessary or
appropriate in order to protect the rights of the Holder. Without limiting the
generality of the foregoing, the Company: (a) will not permit the par value of
any shares of Common Stock receivable upon the exercise of this Warrant (or the
shares of Common Stock thereunder) to exceed the amount payable therefor upon
exercise, (b) will take all actions necessary or appropriate in order that the
Company may validly and legally issue fully paid and nonassessable shares of
Common Stock (or the shares of Common Stock thereunder) on the exercise of the
Warrant and (c) will not take any action which results in any adjustment of the
Exercise Price if the total number of shares of Common Stock (or the shares of
Common Stock thereunder) issuable after the action upon the exercise of the
Warrant would exceed the total number of shares of Common Stock then authorized
by the Company's articles of incorporation and available for the purpose of
issuance upon exercise.

                  5.2 The number of shares of Common Stock issuable upon
exercise of the Warrant may increase substantially in certain circumstances. The
Company acknowledges that

                                       4

<PAGE>
its obligation to issue shares of Common Stock issuable upon exercise of this
Warrant is binding upon it and enforceable regardless of the dilution that such
issuance may have on the ownership interests of other stockholders.

         6. Chief Financial Officer's Report as to Adjustments. In the case of
any adjustment or re-adjustment in the shares of Common Stock or Other
Securities issuable upon the exercise of this Warrant in an amount greater than
1% of such shares of Common Stock or Other Securities, the Company, at its
expense, will promptly compute the adjustment or re-adjustment in accordance
with the terms of this Warrant and cause its Chief Financial Officer to certify
the computation (other than any computation of the fair value of property of the
Company, as the case may be) and prepare a report setting forth the adjustment
or re-adjustment and showing in reasonable detail the method of calculation
thereof and the facts upon which the adjustment or re-adjustment is based,
including a statement of: (a) the number of shares of Common Stock outstanding
or deemed to be outstanding and (b) the Exercise Price in effect immediately
prior to the deemed issuance or sale and as adjusted and re-adjusted (if
required by Section 4 hereof) on account thereof and the number of shares
issuable upon exercise of the Warrant. The Company will forthwith mail a copy of
each report to the Holder and will, upon the reasonable written request at any
time of the Holder, furnish to the Holder a like report setting forth the
Exercise Price at the time in effect and the number of shares issuable upon
exercise of the Warrant and showing in reasonable detail how it was calculated.
The Company will also keep copies of all reports at its office maintained
pursuant to Section 10.2(a) hereof and will cause them to be available for
inspection at the office during normal business hours upon reasonable notice by
the Holder or any prospective purchaser of the Warrant designated by the Holder
thereof.

         7. Reservation of Shares. The Company shall, solely for the purpose of
effecting the exercise of this Warrant, at all times during the term of this
Warrant reserve and keep available out of its authorized shares of Common Stock,
free from all taxes, liens and charges with respect to the issue thereof and not
be subject to preemptive rights or other similar rights of shareholders of the
Company, such number of its shares of Common Stock as shall from time to time be
sufficient to effect the exercise of this Warrant. If at any time the number of
authorized but unissued shares of Common Stock shall not be sufficient to effect
the exercise of this Warrant, in addition to such other remedies as shall be
available to Holder, the Company will take such corporate action as may, in the
opinion of its counsel, be necessary to increase the number of authorized but
unissued shares of Common Stock to such number of shares as shall be sufficient
for such purposes, including without limitation, using its Best Efforts to
obtain the requisite shareholder approval necessary to increase the number of
authorized shares of the Company's Common Stock. The Company hereby represents
and warrants that all shares of Common Stock issuable upon exercise of this
Warrant shall be duly authorized and, when issued and paid for upon exercise,
shall be validly issued and, in the case of shares, fully paid and
nonassessable.

         8. Registration and Listing.

                  8.1 Definition of Registrable Securities; Majority. As used
herein, the term "REGISTRABLE SECURITIES" means any shares of Common Stock
issuable upon the exercise of this Warrant, until three (3) years from the Base
Date or, if earlier, the date (if any) on which such

                                       5
<PAGE>
shares shall have been transferred or exchanged and new certificates for them
not bearing a legend restricting further transfer shall have been delivered by
the Company and subsequent disposition of them shall not require registration or
qualification of them under the Securities Act of 1933, as amended (together
with the rules and regulations promulgated thereunder from time to time, the
"SECURITIES ACT") or any similar state law then in force. For purposes of this
Agreement, the term "Majority" in reference to the holders of Registrable
Securities, shall mean in excess of fifty percent (50%) of the then outstanding
Warrant Shares (assuming the exercise of the entire Warrant) that (i) are not
held by the Company, an affiliate, officer, creditor, employee or agent thereof
or any of their respective affiliates, members of their family, persons acting
as nominees or in conjunction therewith and (ii) have not be resold to the
public pursuant to a registration statement filed under the Securities Act.

                  8.2 Required Registration.

                  (a) At any time on or after the nine (9) month anniversary of
the Base Date and on or before the five (5) year anniversary of the Base Date,
but on not more than one (1) occasion, upon the written request of the holders
of the Registrable Securities representing a "Majority" of such securities, the
Company will use its Best Efforts to effect the registration of the respective
shares of such holders under the Securities Act to the extent requisite to
permit the disposition thereof as expeditiously as reasonably possible, but in
no event later than 120 days from the date of such request.

                  (b) Registrations under this Section 8.2 shall be on such
appropriate registration form: (i) as shall be selected by the Company, and (ii)
as shall permit the disposition of such Registrable Securities in accordance
with this Section 8.2. The Company agrees to include in any such registration
statement all information which the requesting holders shall reasonably request,
which is required to be contained therein.

                  (c) A registration requested pursuant to this Section 8.2
shall not be deemed to have been effected: (i) unless a registration statement
with respect thereto has become effective or (ii) if, after it has become
effective, such registration is interfered with by any stop order, injunction or
other order or requirement of the Securities and Exchange Commission (the "SEC")
or other governmental agency or court of competent jurisdiction for any reason,
other than by reason of some act or omission by a holder of Registrable
Securities.

                  8.3 Company Redemption Right. In connection with a request by
a Majority of the holders of Registrable Securities for registration of
Registrable Securities pursuant to Section 8.2 or 8.4, the Company may, at its
option, in lieu of effecting such registration, redeem for cash all, but not
less than all, of the Warrant Shares then outstanding and held by the requesting
holders of Registrable Securities, out of funds legally available therefor by
paying the Redemption Price. As used herein, the term "REDEMPTION PRICE" shall
mean an amount equal to the sum of (A) an amount derived by multiplying: (i) the
number of Warrant Shares or Other Securities subject to this Warrant at such
time by (ii) the difference of (a) the Fair Market Value on the date such
registration was requested, less (b) the Exercise Price then in effect on the
date such registration was requested. The Company may validly exercise its
redemption right set forth in this Section 8.3 only by providing written notice
thereof to such holders within five (5)

                                       6
<PAGE>

business days of the Company's receipt of holders' written request for
registration and, if such right is validly exercised, the Company shall pay the
aggregate Redemption Price by check or wire transfer of immediately available
funds within fifteen (15) days of the exercise of its redemption right.

                  8.4 Incidental Registration Rights.

                  (a) If the Company, at any time on or after the nine (9) month
anniversary of the Base Date and on or before the five (5) year anniversary of
the Base Date, proposes to register any of its securities under the Securities
Act (other than in connection with the Offering or by a registration on Form S-4
or S-8 or any successor forms) whether for its own account or for the account of
the holder or holders of all shares other than Registrable Securities (any
shares of such holder (but not those of the Company) with respect to any
registration, "OTHER SHARES"), the Company shall each such time give prompt (but
not less than thirty (30) days prior to the anticipated effectiveness thereof)
written notice to the holders of Registrable Securities of its intention to do
so; provided, however, that in no event shall the Company have the obligation to
send any such notice, and the holders will not have any registration rights
under this Section 8.4, if registration rights have been exercised two (2) times
pursuant to this Section 8.4 (except if the Company elected not to proceed with
any such registrations, withdrew such registrations or otherwise failed to
effect the offerings covered by such registrations). Upon the written request of
any such holder made within twenty (20) days after the receipt of any such
notice (which request shall specify the Registrable Securities intended to be
disposed of by such holder), except as set forth in Section 8.4(b), the Company
will use its Best Efforts to effect the registration under the Securities Act of
all of the Registrable Securities which the Company has been so requested to
register by such holder, to the extent requisite to permit the disposition of
the Registrable Securities so to be registered, by inclusion of such Registrable
Securities in the registration statement which covers the securities which the
Company proposes to register; provided, however, that if, at any time after
giving written notice of its intention to register any securities and prior to
the effective date of the registration statement filed in connection with such
registration, the Company shall determine for any reason in its sole discretion
either to not register, to delay or to withdraw registration of such securities,
the Company may, at its election, give written notice of such determination to
such holder and, thereupon, (i) in the case of a determination not to register,
shall be relieved of its obligation to register any Registrable Securities in
connection with such registration (but not from its obligation to pay the
Registration Expenses in connection therewith), without prejudice, however, to
the rights of the holders entitled to do so to request that such registration be
effected as a registration under Section 8.2, (ii) in the case of a
determination to delay registering, shall be permitted to delay registering any
Registrable Securities, for the same period as the delay in registering such
other securities, without prejudice, however, to the rights of the holders
entitled to do so to request that such registration be effected as a
registration under Section 8.2 and (iii) in the case of a determination to
withdraw registration, shall be permitted to withdraw registration, without
prejudice, however, to the rights of the holders entitled to do so to request
that such registration be effected as a registration under Section 8.2. No
registration effected under this Section 8.4 shall relieve the Company of its
obligation to effect any registration upon request under Section 8.2, nor shall
any such registration hereunder be deemed to have been effected pursuant to
Section 8.2. The

                                       7
<PAGE>
Company will pay all Registration Expenses in connection with each registration
of Registrable Securities pursuant to this Section 8.4.

                  (b) If the Company at any time proposes to register any of its
securities under the Securities Act as contemplated by this Section 8.4 and such
securities are to be distributed by or through one or more underwriters, the
Company will, if requested by a holder of Registrable Securities, use its Best
Efforts to arrange for such underwriters to include all the Registrable
Securities to be offered and sold by such holder among the securities to be
distributed by such underwriters, provided that if the managing underwriter of
such underwritten offering shall inform the Company by letter of its belief that
inclusion in such distribution of all or a specified number of such securities
proposed to be distributed by such underwriters would interfere with the
successful marketing of the securities being distributed by such underwriters
(such letter to state the basis of such belief and the approximate number of
such Registrable Securities, such Other Shares and shares held by the Company
proposed so to be registered which may be distributed without such effect), then
the Company may, upon written notice to such holder and holders of such Other
Shares, reduce pro rata in accordance with the number of shares of Common Stock
desired to be included in such registration (if and to the extent stated by such
managing underwriter to be necessary to eliminate such effect) the number of
such Registrable Securities and Other Shares the registration of which shall
have been requested by each holder thereof so that the resulting aggregate
number of such Registrable Securities and Other Shares so included in such
registration, together with the number of securities to be included in such
registration for the account of the Company, shall be equal to the number of
shares stated in such managing underwriter's letter.

                  8.5 Registration Procedures. Whenever the holders of
Registrable Securities have properly requested that any Registrable Securities
be registered pursuant to the terms of this Warrant, the Company shall use its
Best Efforts to effect the registration and the sale of such Registrable
Securities in accordance with the intended method of disposition thereof, and
pursuant thereto the Company shall as expeditiously as possible:

                  (a) prepare and file with the SEC a registration statement

registration statement filed hereunder and prepare and file with the SEC such
amendments and supplements to such registration statement and the prospectus
used in connection therewith as may be necessary to keep such registration
statement effective and the prospectus included therein usable for a period
commencing on the date that such registration statement is initially declared
effective by the SEC and ending on the date when all Registrable Securities
covered by such registration statement have been sold pursuant to the
registration statement or cease to be Registrable Securities, and comply with
the provisions of the Securities Act with respect to the disposition of all
securities covered by such registration statement during such period in
accordance with the intended methods of disposition by the sellers thereof set
forth in such registration statement;

                  (c) furnish to such holders such number of copies of such
registration statement, each amendment and supplement thereto, the prospectus
included in such registration

                                       8
<PAGE>
statement (including each preliminary prospectus) and such other documents as
such seller may reasonably request in order to facilitate the disposition of the
Registrable Securities owned by such holders;

                  (d) use its Best Efforts to register or qualify such
Registrable Securities under such other securities or blue sky laws of such
jurisdictions as the such holders reasonably requests and do any and all other
acts and things which may be reasonably necessary or advisable to enable such
holders to consummate the disposition in such jurisdictions of the Registrable
Securities owned by such holders; provided, however, that the Company shall not
be required to: (i) qualify generally to do business in any jurisdiction where
it would not otherwise be required to qualify but for this subparagraph; (ii)
subject itself to taxation in any such jurisdiction; or (iii) consent to general
service of process in any such jurisdiction;

                  (e) notify such holders, at any time when a prospectus
relating thereto is required to be delivered under the Securities Act, of the
happening of any event as a result of which the prospectus included in such
registration statement contains an untrue statement of a material fact or omits
any material fact necessary to make the statements therein, in light of the
circumstances in which they are made, not materially misleading, and, at the
reasonable request of such holders, the Company shall prepare a supplement or
amendment to such prospectus so that, as thereafter delivered to the purchasers
of such Registrable Securities, such prospectus shall not contain an untrue
statement of a material fact or omit to state any material fact necessary to
make the statements therein, in light of the circumstances in which they are
made, not materially misleading;

                  (f) provide a transfer agent and registrar for all such
Registrable Securities not later than the effective date of such registration
statement;

                  (g) make available for inspection by any underwriter
participating in any disposition pursuant to such registration statement, and
any attorney, accountant or other agent retained by any such underwriter, all
financial and other records, pertinent corporate documents and properties of the
Company, and cause the Company's officers, directors, managers, employees and
independent accountants to supply all information reasonably requested by any
such underwriter, attorney, accountant or agent in connection with such
registration statement;

                  (h) otherwise use its Best Efforts to comply with all
applicable rules and regulations of the SEC, and make available to its security
holders, as soon as reasonably practicable, an earnings statement of the
Company, which earnings statement shall satisfy the provisions of Section 11(a)
of the Securities Act and, at the option of the Company, Rule 158 thereunder;

                  (i) in the event of the issuance of any stop order suspending
the effectiveness of a registration statement, or of any order suspending or
preventing the use of any related prospectus or suspending the qualification of
any Registrable Securities included in such registration statement for sale in
any jurisdiction, the Company shall use its Best Efforts promptly to obtain the
withdrawal of such order;

                                       9
<PAGE>
                  (j) use its Best Efforts to cause any Registrable Securities
covered by such registration statement to be registered with or approved by such
other governmental agencies or authorities as may be necessary to enable the
sellers thereof to consummate the disposition of such Registrable Securities;
and

                  (k) if the offering is underwritten, use its Best Efforts to
furnish on the date that Registrable Securities are delivered to the
underwriters for sale pursuant to such registration, an opinion dated such date
of counsel representing the Company for the purposes of such registration,
addressed to the underwriters covering such issues as are reasonably required by

                  8.6 Listing. The Company shall secure the listing of the

automated quotation system upon which shares of Common Stock are then listed
(subject to official notice of issuance) and shall maintain such listing of

respects with the Company's reporting, filing and other obligations under the
by-laws or rules of the American Stock Exchange (or such other national

                  8.7 Expenses. The Company shall pay all Registration Expenses
relating to the registration and listing obligations set forth in this Section

complying with securities or blue sky laws, (c) all word processing, duplicating
and printing expenses, (d) the fees and disbursements of counsel for the Company
and of its independent public accountants, including the expenses of any special

Securities being registered if the Company desires such insurance, if any;
provided however, that, in any case where Registration Expenses are not to be
borne by the Company, such expenses shall not include: (i) salaries of Company
personnel or general overhead expenses of the Company, (ii) auditing fees, (iii)
premiums or other expenses relating to liability insurance required by
underwriters of the Company, or (iv) other expenses for the preparation of

place. Registration Expenses shall not include any underwriting discounts and
commissions which may be incurred in the sale of any Registrable Securities,

sixty (60) days prior to the Company's good faith estimate of the date of filing
of, and ending on a date one hundred twenty (120) days after the effective date
of, a Company-initiated registration (other than a registration pursuant to Form
S-8), provided that: (i) if the holder of Registrable Securities elects to have
all or some of its Registrable Securities included in the registration pursuant
to Section 8.4 hereof, such Registrable Securities are included in the
Company-initiated registration statement only to

                                       10
<PAGE>
the extent required hereunder and (ii) the Company is actively employing in Best
Efforts to cause such registration to become effective.

                  8.9 Information Provided by Holders. Any holder of Registrable
Securities included in any registration shall furnish to the Company such
information as the Company may reasonably request in writing to enable the
Company to comply with the provisions hereof in connection with any registration
referred to in this Agreement. In the event that a holder of Registrable
Securities fails to provide such information on a timely basis, and in any event
within seven (7) business days of the Company's written request, then the
Company shall be entitled to exclude the Registrable Securities of such holder
from such registration and the Company shall nevertheless be deemed to have
satisfied its obligations hereunder with respect to such registration.

                  8.10 Indemnification. Any holder of Registrable Securities to
be sold pursuant to a registration statement under this Section 8, and its

whatsoever) to which they may become subject under the Securities Act, the
Exchange Act or otherwise, arising from: (i) information furnished in writing by
or on behalf of such holder, or its successors or assigns, for specific
inclusion in such registration statement or (ii) any action taken, or failure to
take action, by such holder, or its successors or assigns, which would be
considered unlawful under Section 12 of the Securities Act or Rule 10b-5 of the
Exchange Act.

         9. Restrictions on Transfer.

                  9.1 Restrictive Legends. This Warrant and each Warrant issued
upon transfer or in substitution for this Warrant pursuant to Section 10 hereof,
each certificate for Common Stock issued upon the exercise of the Warrant and
each certificate issued upon the transfer of any such Common Stock shall be
transferable only upon satisfaction of the conditions specified in this Section
9. Each of the foregoing securities shall be stamped or otherwise imprinted with
a legend reflecting the restrictions on transfer set forth herein and any
restrictions required under the Securities Act or other applicable securities
laws.

                  9.2 Notice of Proposed Transfer. Prior to any transfer of any
securities which are not registered under an effective registration statement
under the Securities Act ("RESTRICTED SECURITIES"), which transfer may only
occur if there is an exemption from the registration provisions of the
Securities Act and all other applicable securities laws, the Holder will give
written notice to the Company of the Holder's intention to affect a transfer and
to comply in all other respects with this Section 9.2. Each notice: (a) shall
describe the manner and circumstances of the proposed transfer, and (b) shall
designate special counsel for the Holder giving the notice. The Holder giving
notice will submit a copy thereof to the counsel designated in the notice. The
following provisions shall then apply:

                                       11
<PAGE>
                           (i) If in the opinion of counsel for the Holder
satisfactory to the Company the proposed transfer may be effected without
registration of the Restricted Securities under the Securities Act (which
opinion shall state in detail the basis of the legal conclusions reached
therein) and with satisfaction of all other applicable securities laws, the
Holder shall thereupon be entitled to transfer the Restricted Securities in
accordance with the terms of the notice delivered by the Holder to the Company.
Each certificate representing the Restricted Securities issued upon or in
connection with any transfer shall bear the restrictive legends required by
Section 9.1 hereof.

                           (ii) If the opinion called for in (i) above is not
delivered, the Holder shall not be entitled to transfer the Restricted
Securities until either (x) receipt by the Company of a further notice from such
Holder pursuant to the foregoing provisions of this Section 9.2 and fulfillment
of the provisions of clause (i) above, or (y) such Restricted Securities have
been effectively registered under the Securities Act.

                  Notwithstanding any other provision of this Section 9, no
opinion of counsel shall be necessary for a transfer of Restricted Securities by
the holder thereof to any Person employed by or owning equity in the Holder, if
the transferee agrees in writing to be subject to the terms hereof to the same
extent as if the transferee were the original purchaser hereof and such transfer
is permitted under applicable securities laws.

                  9.3 Termination of Restrictions. The restrictions imposed by
this Section 10 upon the transferability of Restricted Securities shall cease
and terminate as to any particular Restricted Securities: (a) which Restricted
Securities shall have been effectively registered under the Securities Act, or
(b) when, in the opinions of both counsel for the holder thereof and counsel for
the Company, such restrictions are no longer required in order to insure
compliance with the Securities Act or Section 10 hereof. Whenever such
restrictions shall cease and terminate as to any Restricted Securities, the
Holder thereof shall be entitled to receive from the Company, without expense
(other than applicable transfer taxes, if any), new securities of like tenor not
bearing the applicable legends required by Section 9.1 hereof.

         10. Ownership, Transfer and Substitution of Warrant.

                  10.1 Ownership of Warrant. The Company may treat the person in
whose name this Warrant is registered in the Warrant Register maintained
pursuant to Section 10.2(a) hereof as the owner and holder thereof for all
purposes, notwithstanding any notice to the contrary, except that, if and when
any Warrant is properly assigned in blank, the Company may (but shall not be
obligated to) treat the bearer thereof as the owner of such Warrant for all
purposes, notwithstanding any notice to the contrary. Subject to Sections 9 and
10 hereof, this Warrant, if properly assigned, may be exercised by a new holder
without a new Warrant first having been issued.

                  10.2 Office; Exchange of Warrant.

                  (a) The Company will maintain its principal office at the
location identified in the prospectus relating to the Offering or at such other
offices as set forth in the Company's most

                                       12
<PAGE>
current filing (as of the date notice is to be given) under the Exchange Act or
as the Company notifies the Holders.

                  (b) The Company shall cause to be kept at its office
maintained pursuant to Section 10.2(a) hereof a Warrant Register for the
registration and transfer of the Warrant. The name and address of the holder of
the Warrant, the transfers thereof and the name and address of the transferee of
the Warrant shall be registered in such Warrant Register. The Person in whose
name the Warrant shall be so registered shall be deemed and treated as the owner
and holder thereof for all purposes of this Warrant, and the Company shall not
be affected by any notice or knowledge to the contrary.

                  (c) Upon the surrender of this Warrant, properly endorsed, for
registration of transfer or for exchange at the office of the Company maintained
pursuant to Section 10.2(a) hereof, the Company at its expense will (subject to
compliance with Section 9 hereof, if applicable) execute and deliver to or upon
the order of the Holder thereof a new Warrant of like tenor, in the name of such
holder or as such holder (upon payment by such holder of any applicable transfer
taxes) may direct, calling in the aggregate on the face thereof for the number
of shares of Common Stock called for on the face of the Warrant so surrendered.

                  10.3 Replacement of Warrant. Upon receipt of evidence
reasonably satisfactory to the Company of the loss, theft, destruction or
mutilation of this Warrant and, in the case of any such loss, theft or
destruction of this Warrant, upon delivery of indemnity reasonably satisfactory
to the Company in form and amount or, in the case of any mutilation, upon
surrender of this Warrant for cancellation at the office of the Company
maintained pursuant to Section 10.2(a) hereof, the Company, at its expense, will
execute and deliver, in lieu thereof, a new Warrant of like tenor and dated the
date hereof.

         11. No Rights or Liabilities as Stockholder. No Holder shall be
entitled to vote or receive dividends or be deemed the holder of any shares of
Common Stock, Other Securities or any other securities of the Company which may
at any time be issuable on the exercise hereof for any purpose, nor shall
anything contained herein be construed to confer upon the Holder, as such, any
of the rights of a stockholder of the Company or any right to vote for the
election of directors or upon any matter submitted to stockholders at any
meeting thereof, or to give or withhold consent to any corporate action (whether
upon any recapitalization, issuance of stock, reclassification of stock, change
of par value, consolidation, merger, conveyance, or otherwise) or to receive
notice of meetings, or to receive dividends or subscription rights or otherwise
until the Warrant shall have been exercised and the shares of Common Stock
purchasable upon the exercise hereof shall have become deliverable, as provided
herein. The Holder will not be entitled to share in the assets of the Company in
the event of a liquidation, dissolution or the winding up of the Company.

         12. Notices. Any notice or other communication in connection with this
Warrant shall be given in writing and directed to the parties hereto as follows:

Warrant shall also be effected in the manner provided in Section 3 hereof.

transmission thereof generated by the sending telecopy machine, (iii) if sent by
a commercial overnight courier for delivery on the next Business Day, on the
first Business Day after deposit with such courier service, or (iv) if sent by
registered or certified mail, five (5) Business Days after deposit thereof in
the U.S. mail.

         13. Payment of Taxes. The Company will pay all documentary stamp taxes
attributable to the issuance of shares of Common Stock underlying this Warrant
upon exercise of this Warrant; provided, however, that the Company shall not be
required to pay any tax which may be payable in respect of any transfer involved
in the transfer or registration of this Warrant or any certificate for shares of
Common Stock underlying this Warrant in a name other that of the Holder. The
Holder is responsible for all other tax liability that may arise as a result of
holding or transferring this Warrant or receiving shares of Common Stock
underlying this Warrant upon exercise hereof.

         14. Miscellaneous. This Warrant and any term hereof may be changed,
waived, discharged or terminated only by an instrument in writing signed by the
party against which enforcement of the change, waiver, discharge or termination
is sought. This Warrant shall be construed and enforced in accordance with and
governed by the laws of the State of Illinois. The section headings in this
Warrant are for purposes of convenience only and shall not constitute a part
hereof. When used herein, the term "Best Efforts" means, with respect to the
