                  The Depositor intends to sell pass-through certificates to be
issued hereunder in multiple classes, which in the aggregate will evidence the
entire beneficial ownership interest of the Trust Fund created hereunder. The
Trust Fund will consist of a segregated pool of assets comprised of the Mortgage
Loans and certain other related assets subject to this Agreement.

                                     REMIC I
                                     -------

                  As provided herein, the Trustee will elect to treat the
segregated pool of assets consisting of the Mortgage Loans and certain other
related assets subject to this Agreement (other than the Reserve Fund) as a
REMIC for federal income tax purposes, and such segregated pool of assets will
be designated as "REMIC I". The Class R-I Interest will be the sole class of
"residual interests" in REMIC I for purposes of the REMIC Provisions (as defined
herein). The following table irrevocably sets forth the designation, the REMIC I
Remittance Rate, the initial Uncertificated Balance and, solely for purposes of
satisfying Treasury regulation Section 1.860G-1(a)(4)(iii), the "latest possible

appears on Telerate Page 3750 as of 11:00 a.m. (London time) on such Interest
Determination Date; provided that if such rate does not appear on Telerate Page
3750, the rate for such date will be determined on the basis of the offered

a.m. (London time) on such Interest Determination Date. In such event, the
Securities Administrator will request the principal London office of each of the
Reference Banks to provide a quotation of its rate. If on such Interest
Determination Date, two or more Reference Banks provide such offered quotations,
One-Month LIBOR for the related Interest Accrual Period shall be the arithmetic
mean of such offered quotations (rounded upwards if necessary to the nearest

Reference Banks provide such offered quotations, One-Month LIBOR for the related
Interest Accrual Period shall be the higher of (i) LIBOR as determined on the
previous Interest Determination Date and (ii) the Reserve Interest Rate.

one-month Eurodollar lending rates that is calculated and published (or
otherwise made available) by an independent party. The establishment of

Administrator's subsequent calculation of the One-Month LIBOR Pass-Through Rates
for the relevant Interest Accrual Period, shall, in the absence of manifest
error, be final and binding.

                          CONVEYANCE OF MORTGAGE LOANS;
                        ORIGINAL ISSUANCE OF CERTIFICATES

                    SECTION 2.01. Conveyance of the Mortgage Loans.

                    The Depositor, concurrently with the execution and delivery
hereof, does hereby transfer, assign, set over and otherwise convey to the
Trustee, on behalf of the Trust, without recourse, for the benefit of the
Certificateholders, all the right, title and interest of the Depositor,
including any security interest therein for the benefit of the Depositor, in and
to the Mortgage Loans identified on the Mortgage Loan Schedule, the rights of
the Depositor under the Mortgage Loan Purchase Agreement (including, without

thereunder), and all other assets included or to be included in REMIC I. Such
assignment includes all interest and principal received by the Depositor or the
Servicer on or with respect to the Mortgage Loans (other than payments of
principal and interest due on such Mortgage Loans on or before the Cut-off
Date). The Depositor herewith delivers to the Trustee and the Servicer an
executed copy of the Mortgage Loan Purchase Agreement.

                    In connection with such transfer and assignment, the
Depositor does hereby deliver to, and deposit with the Custodian pursuant to the
Custodial Agreement the documents with respect to each Mortgage Loan as
described under Section 2 of the Custodial Agreement (the "Mortgage Loan
Documents"). In connection with such delivery and as further described in the
Custodial Agreement, the Custodian will be required to review such Mortgage Loan
Documents and deliver to the Trustee, the Depositor, the Servicer and the Seller
certifications (in the forms attached to the Custodial Agreement) with respect
to such review with exceptions noted thereon. In addition, under the Custodial
Agreement the Depositor will be required to cure certain defects with respect to
the Mortgage Loan Documents for the related Mortgage Loans after the delivery
thereof by the Depositor to the Custodian as more particularly set forth
therein.

                    Notwithstanding anything to the contrary contained herein,
the parties hereto acknowledge that the functions of the Trustee with respect to
the custody, acceptance, inspection and release of the Mortgage Files,
including, but not limited to certain insurance policies and documents
contemplated by Section 4.12, and preparation and delivery of the certifications
shall be performed by the Custodian pursuant to the terms and conditions of the
Custodial Agreement.

                    SECTION 2.02. Acceptance of REMIC I by Trustee.

                    The Trustee acknowledges receipt, subject to the provisions

behalf holds) and will hold such documents and the other documents delivered to

                    SECTION 2.03. Repurchase or Substitution of Mortgage Loans.

                    (a) Upon discovery or receipt of notice of any materially
defective document in, or that a document is missing from, a Mortgage File or of
a breach by the Seller of any representation, warranty or covenant under the
Mortgage Loan Purchase Agreement in respect of any Mortgage Loan that materially
and adversely affects the value of such Mortgage Loan or the interest therein of
the Certificateholders, the Trustee shall promptly notify the Seller and the
Servicer of such defect, missing document or breach and request that the Seller
deliver such missing document, cure such defect or breach within 60 days from
the date the Seller was notified of such missing document, defect or breach, and
if the Seller does not deliver such missing document or cure such defect or
breach in all material respects during such period, the Trustee shall enforce
the obligations of the Seller under the Mortgage Loan Purchase Agreement to
repurchase such Mortgage Loan from REMIC I at the Purchase Price within 90 days
after the date on which the Seller was notified of such missing document, defect
or breach, if and to the extent that the Seller is obligated to do so under the
Mortgage Loan Purchase Agreement. The Purchase Price for the repurchased
Mortgage Loan shall be remitted to the Servicer for deposit in the Collection
Account and the Trustee, upon receipt of written certification from the Servicer
of such deposit, shall release or cause the Custodian (upon receipt of a request
for release in the form attached to the Custodial Agreement) to release to the
Seller the related Mortgage File and the Trustee shall execute and deliver such
instruments of transfer or assignment, in each case without recourse,
representation or warranty, as the Seller shall furnish to it and as shall be
necessary to vest in the Seller any Mortgage Loan released pursuant hereto, and
the Trustee shall not have any further responsibility with regard to such
Mortgage File. In lieu of repurchasing any such Mortgage Loan as provided above,
if so provided in the Mortgage Loan Purchase Agreement, the Seller may cause
such Mortgage Loan to be removed from REMIC I (in which case it shall become a
Deleted Mortgage Loan) and substitute one or more Qualified Substitute Mortgage
Loans in the manner and subject to the limitations set forth in Section 2.03(b).
It is understood and agreed that the obligation of the Seller to cure or to
repurchase (or to substitute for) any Mortgage Loan as to which a document is
missing, a material defect in a constituent document exists or as to which such
a breach has occurred and is continuing shall constitute the sole remedy
respecting such omission, defect or breach available to the Trustee and the
Certificateholders.

                    In addition, promptly upon the earlier of discovery by the
Servicer or receipt of notice by the Servicer of the breach of the
representation or covenant of the Seller set forth in Section 5(xiv) of the
Mortgage Loan Purchase Agreement which materially and adversely affects the
interests of the Holders of the Class P Certificates in any Prepayment Charge,
the Servicer shall promptly notify the Seller and the Trustee of such breach.
The Trustee shall enforce the obligations of the Seller under the Mortgage Loan
Purchase Agreement to remedy such breach to the extent and in the manner set
forth in the Mortgage Loan Purchase Agreement.

                    (b) Any substitution of Qualified Substitute Mortgage Loans
for Deleted Mortgage Loans made pursuant to Section 2.03(a) must be effected
prior to the date which is two years after the Startup Day for REMIC I.

                    As to any Deleted Mortgage Loan for which the Seller,
substitutes a Qualified Substitute Mortgage Loan or Loans, such substitution
shall be effected by the Seller delivering to

                                      -59-
<PAGE>

the Trustee or the Custodian on behalf of the Trustee, for such Qualified
Substitute Mortgage Loan or Loans, the Mortgage Note, the Mortgage, the
Assignment to the Trustee, and such other documents and agreements, with all
necessary endorsements thereon, as are required by Section 2 of the Custodial
Agreement, as applicable, together with an Officers' Certificate providing that
each such Qualified Substitute Mortgage Loan satisfies the definition thereof
and specifying the Substitution Shortfall Amount (as described below), if any,
in connection with such substitution. The Custodian on behalf of the Trustee
shall acknowledge receipt of such Qualified Substitute Mortgage Loan or Loans
and, within ten Business Days thereafter, review such documents and deliver to
the Depositor, the Trustee and the Servicer, with respect to such Qualified
Substitute Mortgage Loan or Loans, an initial certification pursuant to the
Custodial Agreement, with any applicable exceptions noted thereon. Within one
year of the date of substitution, the Custodian on behalf of the Trustee shall
deliver to the Depositor, the Trustee and the Servicer a final certification
pursuant to the Custodial Agreement with respect to such Qualified Substitute
Mortgage Loan or Loans, with any applicable exceptions noted thereon. Monthly
Payments due with respect to Qualified Substitute Mortgage Loans in the month of
substitution are not part of REMIC I and will be retained by the Seller. For the
month of substitution, distributions to Certificateholders will reflect the
Monthly Payment due on such Deleted Mortgage Loan on or before the Due Date in
the month of substitution, and the Seller shall thereafter be entitled to retain
all amounts subsequently received in respect of such Deleted Mortgage Loan. The
Depositor shall give or cause to be given written notice to the
Certificateholders that such substitution has taken place, shall amend the
Mortgage Loan Schedule to reflect the removal of such Deleted Mortgage Loan from
the terms of this Agreement and the substitution of the Qualified Substitute
Mortgage Loan or Loans and shall deliver a copy of such amended Mortgage Loan
Schedule to the Trustee and the Servicer. Upon such substitution, such Qualified
Substitute Mortgage Loan or Loans shall constitute part of the Trust Fund and
shall be subject in all respects to the terms of this Agreement and the Mortgage
Loan Purchase Agreement including all applicable representations and warranties
thereof included herein or in the Mortgage Loan Purchase Agreement.

                    For any month in which the Seller substitutes one or more
Qualified Substitute Mortgage Loans for one or more Deleted Mortgage Loans, the
Servicer will determine the amount (the "Substitution Shortfall Amount"), if
any, by which the aggregate Purchase Price of all such Deleted Mortgage Loans
exceeds the aggregate of, as to each such Qualified Substitute Mortgage Loan,
the Scheduled Principal Balance thereof as of the date of substitution, together
with one month's interest on such Scheduled Principal Balance at the applicable
Net Mortgage Rate, plus all outstanding P&I Advances and Servicing Advances
(including Nonrecoverable P&I Advances and Nonrecoverable Servicing Advances)
related thereto. On the date of such substitution, the Seller will deliver or
cause to be delivered to the Servicer for deposit in the Collection Account an
amount equal to the Substitution Shortfall Amount, if any, and the Trustee or
the Custodian on behalf of the Trustee, upon receipt of the related Qualified
Substitute Mortgage Loan or Loans, upon receipt of a request for release in the
form attached to the Custodial Agreement and certification by the Servicer of
such deposit, shall release to the Seller the related Mortgage File or Files and
the Trustee shall execute and deliver such instruments of transfer or
assignment, in each case without recourse, representation or warranty, as the
Seller shall deliver to it and as shall be necessary to vest therein any Deleted
Mortgage Loan released pursuant hereto.

                                      -60-
<PAGE>

                    In addition, the Seller shall obtain at its own expense and
deliver to the Trustee an Opinion of Counsel to the effect that such
substitution will not cause (a) any federal tax to be imposed on any Trust
REMIC, including without limitation, any federal tax imposed on "prohibited
transactions" under Section 860F(a)(1) of the Code or on "contributions after
the startup date" under Section 860G(d)(1) of the Code, or (b) any Trust REMIC
to fail to qualify as a REMIC at any time that any Certificate is outstanding.

                    (c) Upon discovery by the Depositor, the Seller, the
Servicer or the Trustee that any Mortgage Loan does not constitute a "qualified
mortgage" within the meaning of Section 860G(a)(3) of the Code, the party
discovering such fact shall within two Business Days give written notice thereof
to the other parties. In connection therewith, the Seller shall repurchase or
substitute one or more Qualified Substitute Mortgage Loans for the affected
Mortgage Loan within 90 days of the earlier of discovery or receipt of such
notice with respect to such affected Mortgage Loan. Such repurchase or
substitution shall be made by (i) the Seller if the affected Mortgage Loan's
status as a non-qualified mortgage is or results from a breach of any
representation, warranty or covenant made by the Seller under the Mortgage Loan
Purchase Agreement or (ii) the Depositor, if the affected Mortgage Loan's status
as a non-qualified mortgage is a breach of no representation or warranty. Any
such repurchase or substitution shall be made in the same manner as set forth in
Section 2.03(a). The Trustee shall reconvey to the Seller the Mortgage Loan to
be released pursuant hereto in the same manner, and on the same terms and
conditions, as it would a Mortgage Loan repurchased for breach of a
representation or warranty.

                    (d) With respect to a breach of the representations made
pursuant to Section 5(xiv) of the Mortgage Loan Purchase Agreement that
materially and adversely affects the value of such Mortgage Loan or the interest
therein of the Certificateholders, the Seller shall be required to take the
actions set forth in this Section 2.03.

                    (e) Within 90 days of the earlier of discovery by the
Servicer or receipt of notice by the Servicer of the breach of any
representation, warranty or covenant of the Servicer set forth in Section 2.05
which materially and adversely affects the interests of the Certificateholders
in any Mortgage Loan or Prepayment Charge, the Servicer shall cure such breach
in all material respects.

                    SECTION 2.04. Representations and Warranties of the Master
                                  Servicer.

                    The Master Servicer hereby represents, warrants and
covenants to the Servicer, the Depositor and the Trustee, for the benefit of

                  required under applicable law to effect such qualification
                  and, in any event, is in compliance with the doing business

                  hereunder, the consummation by the Servicer of any other of
                  the transactions herein contemplated, and the fulfillment of
                  or compliance with the terms hereof are in the ordinary course

                  or subject to or in violation of any statute, order or
                  regulation of any court, regulatory body, administrative

                  Section 203 and Section 211 of the National Housing Act. No
                  event has occurred, including but not limited to a change in
                  insurance coverage, that would make the Servicer unable to
                  comply with HUD eligibility requirements or that would require
                  notification to HUD;

                    (v) The Servicer does not believe, nor does it have any
                  reason or cause to believe, that it cannot perform each and

                    (vi) No litigation is pending against the Servicer that
                  would materially and adversely affect the execution, delivery
                  or enforceability of this Agreement or the ability of the
                  Servicer to service the Mortgage Loans or to perform any of
                  its other obligations hereunder in accordance with the terms
                  hereof;

                    (vii) There are no actions or proceedings against, or
                  investigations known to it of, the Servicer before any court,
                  administrative or other tribunal (A) that might prohibit its
                  entering into this Agreement, (B) seeking to prevent the
                  consummation of the transactions contemplated by this
                  Agreement or (C) that might prohibit or materially and
                  adversely affect the performance by the Servicer of its
                  obligations under, or the validity or enforceability of, this
                  Agreement;

                    (viii) No consent, approval, authorization or order of any
                  court or governmental agency or body is required for the
                  execution, delivery and performance by the Servicer of, or
                  compliance by the Servicer with, this Agreement or the
                  consummation by it of the transactions contemplated by this
                  Agreement, except for such consents, approvals, authorizations
                  or orders, if any, that have been obtained prior to the
                  Closing Date;

                    (ix) The Servicer does and will continue to accurately
                  report its borrower credit files for each Mortgage Loan to the
                  three major credit bureaus in existence as of the Closing Date
                  in a timely manner; and

                    (x) The Servicer is a member of MERS in good standing, and
                  will comply in all material respects with the rules and
                  procedures of MERS in connection with the servicing of the
                  Mortgage Loans that are registered with MERS.

                    It is understood and agreed that the representations,
warranties and covenants set forth in this Section 2.05 shall survive the
resignation or termination of the parties hereto, the termination of this
Agreement and the delivery of the Mortgage Files to the Custodian and shall
inure to the benefit of the Trustee, the Master Servicer, the Securities
Administrator, the Depositor and the Certificateholders. Upon discovery by any
such Person or the Servicer of a breach of any of the foregoing representations,
warranties and covenants which materially and adversely affects the value of any
Mortgage Loan, Prepayment Charge or the interests therein of the
Certificateholders, the party discovering such breach shall give prompt written
notice (but in no event later than two Business Days following such discovery)
to the Trustee. Subject to Section 8.01, unless such breach shall not be
susceptible of cure within 90 days, the obligation of the Servicer set forth in
Section 2.03(c) to cure breaches shall constitute the sole remedy against the
Servicer available to the Certificateholders, the Depositor or the Trustee on
behalf of the Certificateholders respecting a breach of the representations,
warranties and covenants contained in this Section 2.05.

                    The Trustee acknowledges the assignment to it of the REMIC I
Regular Interests and the REMIC II Regular Interests and, concurrently therewith

in accordance with the provisions of this Agreement.

                                   ARTICLE III

                          ADMINISTRATION AND SERVICING
                         OF THE MORTGAGE LOANS; ACCOUNTS

                  SECTION 3.01. Servicer to Act as Servicer.

                  The Servicer shall service and administer the Mortgage Loans
on behalf of the Trust Fund and in the best interests of and for the benefit of
the Certificateholders (as determined by the Servicer in its reasonable
judgment) in accordance with the terms of this Agreement and the respective
Mortgage Loans and all applicable law and regulations and, to the extent
consistent with such terms, in the same manner in which it services and
administers similar mortgage loans for its own portfolio, giving due
consideration to customary and usual standards of practice of prudent mortgage
lenders and loan servicers administering similar mortgage loans but without
regard to:

                  (i) any relationship that the Servicer or any Affiliate of the
         Servicer may have with the related Mortgagor;

                  (ii) the ownership of any Certificate by the Servicer or any
         Affiliate of the Servicer;

                  (iii) the Servicer's obligation to make P&I Advances or
         Servicing Advances; or

                  (iv) the Servicer's right to receive compensation for its
         services hereunder.

                  To the extent consistent with the foregoing, the Servicer
shall also seek to maximize the timely and complete recovery of principal and
interest on the Mortgage Notes. Subject only to the above-described servicing
standards (the "Accepted Servicing Practices") and the terms of this Agreement
and of the respective Mortgage Loans, the Servicer shall have full power and
authority, to do or cause to be done any and all things in connection with such
servicing and administration

                                      -66-
<PAGE>

which it may deem necessary or desirable. Without limiting the generality of the
foregoing, the Servicer in its own name is hereby authorized and empowered by
the Trustee when the Servicer believes it appropriate in its best judgment, to
execute and deliver, on behalf of the Trust Fund, the Certificateholders and the
Trustee or any of them, and upon written notice to the Trustee, any and all
instruments of satisfaction or cancellation, or of partial or full release or
discharge, and all other comparable instruments, with respect to the Mortgage
Loans and the Mortgaged Properties and to institute foreclosure proceedings or
obtain a deed-in-lieu of foreclosure so as to convert the ownership of such
properties, and to hold or cause to be held title to such properties, on behalf
of the Trustee, for the benefit of the Trust Fund and the Certificateholders.
The Servicer shall service and administer the Mortgage Loans in accordance with
applicable state and federal law and shall provide to the Mortgagors any reports
required to be provided to them thereby. The Servicer shall also comply in the
performance of this Agreement with all reasonable rules and requirements of each
insurer under any standard hazard insurance policy. Subject to Section 3.14, the
Trustee shall execute, at the written request of the Servicer, and furnish to
the Servicer any special or limited powers of attorney and other documents
necessary or appropriate to enable the Servicer to carry out its servicing and
administrative duties hereunder and furnished to the Trustee by the Servicer,
and the Trustee shall not be liable for the actions of the Servicer under such
powers of attorney and shall be indemnified by the Servicer for any cost,
liability or expense incurred by the Trustee in connection with the Servicer's
use or misuse of any such power of attorney.

                  In accordance with Accepted Servicing Practices, the Servicer
shall make or cause to be made Servicing Advances as necessary for the purpose
of effecting the payment of taxes and assessments on the Mortgaged Properties,
which Servicing Advances shall be reimbursable in the first instance from
related collections from the Mortgagors pursuant to Section 3.07, and further as
provided in Section 3.09; provided, however, the Servicer shall only make such
Servicing Advance if the Mortgagor has not made such payment, if the failure to
make such Servicing Advance would result in the loss of the Mortgaged Property
due to a tax sale or foreclosure as result of a tax lien. Any cost incurred by
the Servicer in effecting the payment of taxes and assessments on a Mortgaged
Property shall not, for the purpose of calculating the Stated Principal Balance
of a Mortgage Loan or distributions to Certificateholders, be added to the
unpaid principal balance of the related Mortgage Loan, notwithstanding that the
terms of such Mortgage Loan so permit.

                  The Servicer further is authorized and empowered by the
Trustee, on behalf of the Certificateholders and the Trustee, in its own name or
in the name of the Sub-Servicer, when the Servicer or the Sub-Servicer, as the
case may be, believes it is appropriate in its best judgment to register any
Mortgage Loan on the MERS(R) System, or cause the removal from the registration
of any Mortgage Loan on the MERS(R) System, to execute and deliver, on behalf of
the Trustee and the Certificateholders or any of them, any and all instruments
of assignment and other comparable instruments with respect to such assignment
or re-recording of a Mortgage in the name of MERS, solely as nominee for the
Trustee and its successors and assigns. Any reasonable expenses incurred in
connection with the actions described in the preceding sentence or as a result
of MERS discontinuing or becoming unable to continue operations in connection
with the MERS(R) System, shall be subject to withdrawal by the Servicer from the
Collection Account.

                  Notwithstanding anything in this Agreement to the contrary,
the Servicer may not make any future advances with respect to a Mortgage Loan
and the Servicer shall not permit any

                                      -67-

modification with respect to any Mortgage Loan that would change the Mortgage
Rate, reduce or increase the principal balance (except for reductions resulting
from actual payments of principal) or change the final maturity date on such
Mortgage Loan (unless, as provided in Section 3.06, the Mortgagor is in default
with respect to the Mortgage Loan or such default is, in the judgment of the
Servicer, reasonably foreseeable) or any modification, waiver or amendment of
any term of any Mortgage Loan that would both (A) effect an exchange or
reissuance of such Mortgage Loan under Section 1001 of the Code (or final,
temporary or proposed Treasury regulations promulgated thereunder) and (B) cause
any Trust REMIC created hereunder to fail to qualify as a REMIC under the Code
or the imposition of any tax on "prohibited transactions" or "contributions
after the startup date" under the REMIC Provisions.

                  Notwithstanding anything in this Agreement to the contrary, in
the event of a Principal Prepayment in full of a Mortgage Loan, the Servicer may
not waive any Prepayment Charge or portion thereof required by the terms of the
related Mortgage Note unless (i) the Servicer determines that such waiver would
maximize recovery of Liquidation Proceeds for such Mortgage Loan, taking into
account the value of such Prepayment Charge, (ii)(A) the enforceability thereof
is limited (1) by bankruptcy, insolvency, moratorium, receivership, or other
similar law relating to creditors' rights generally or (2) due to acceleration
in connection with a foreclosure or other involuntary payment, or (B) the
enforceability is otherwise limited or prohibited by applicable law or (iii) the
Servicer has not been provided with information sufficient to enable it to
collect the Prepayment Charge. If a Prepayment Charge is waived as permitted by
meeting the standard described in clause (iii) above, then the Servicer shall
enforce the obligation of the Seller to pay the amount of such waived Prepayment
Charge to the Servicer for deposit in the Collection Account (to the extent paid
by the Seller) for the benefit of the Holders of the Class P Certificates.

                  Promptly upon the earlier of discovery by the Servicer or
receipt of notice by the Servicer of the breach of the covenant of the Servicer
set forth above which materially and adversely affects the interests of the
Holders of the Class P Certificates in any Prepayment Charge, the Servicer shall
promptly pay the amount of such waived Prepayment Charge (or such portion
thereof as had been waived), (the "Servicer Prepayment Charge Payment Amount")
for the benefit of the holders of the Class P Certificates by depositing such
amount into the Collection Account for distribution in accordance with the terms
of this Agreement. The foregoing shall not, however, limit any remedies
available to the Certificateholders, the Depositor or the Trustee on behalf of
the Trust Fund and for the benefit of the Certificateholders, pursuant to the
Mortgage Loan Purchase Agreement, respecting a breach of the representations,
warranties and covenants of the Seller contained in the Mortgage Loan Purchase
Agreement.

                  As part of its servicing activities hereunder, the Servicer,
for the benefit of the Trustee and the Certificateholders, shall enforce the
obligations of the Seller under the Mortgage Loan Purchase Agreement, including,
without limitation, any obligation of the Seller to purchase a Mortgage Loan on
account of missing or defective documentation or on account of a breach of a
representation, warranty or covenant, as described in Section 2.03(a).

                  SECTION 3.02. Sub-Servicing Agreements Between Servicer and
                                Sub-Servicers.

                                      -68-

                  The Servicer may arrange for the subservicing of any Mortgage
Loan by a Sub- Servicer pursuant to a Sub-Servicing Agreement; provided that
such sub-servicing arrangement and the terms of the related Sub-Servicing
Agreement must provide for the servicing of such Mortgage Loans in a manner
consistent with the servicing arrangements contemplated hereunder.
Notwithstanding the provisions of any Sub-Servicing Agreement, any of the
provisions of this Agreement relating to agreements or arrangements between the
Servicer or a Sub-Servicer or reference to actions taken through a Servicer or
otherwise, the Servicer shall remain obligated and liable to the Depositor, the
Trustee and the Certificateholders for the servicing and administration of the
Mortgage Loans in accordance with the provisions of this Agreement without
diminution of such obligation or liability by virtue of such Sub-Servicing
Agreements or arrangements or by virtue of indemnification from the Sub-Servicer
and to the same extent and under the same terms and conditions as if the
Servicer alone were servicing and administering the Mortgage Loans. Every Sub-
Servicing Agreement entered into by the Servicer shall contain a provision
giving the successor Servicer the option to terminate such agreement in the
event a successor Servicer is appointed. All actions of each Sub-Servicer
performed pursuant to the related Sub-Servicing Agreement shall be performed as
an agent of the Servicer with the same force and effect as if performed directly
by the Servicer.

                  For purposes of this Agreement, the Servicer shall be deemed
to have received any collections, recoveries or payments with respect to the
Mortgage Loans that are received by a Sub- Servicer regardless of whether such
payments are remitted by the Sub-Servicer to the Servicer.

                  SECTION 3.03. Successor Sub-Servicers.

                  Any Sub-Servicing Agreement shall provide that Servicer shall
be entitled to terminate any Sub-Servicing Agreement and to either itself
directly service the related Mortgage Loans or enter into a Sub-Servicing
Agreement with a successor Sub-Servicer which qualifies under Section 3.02. Any
Sub-Servicing Agreement shall include the provision that such agreement may be
immediately terminated by the successor Servicer (which may be the Trustee or
the Master Servicer) without fee, in accordance with the terms of this
Agreement, in the event that the Servicer (or any successor Servicer) shall, for
any reason, no longer be the Servicer (including termination due to a Servicer
Event of Default).

                  SECTION 3.04. No Contractual Relationship Between
                                Sub-Servicer, Trustee or the Certificateholders.

                  Any Sub-Servicing Agreement and any other transactions or
services relating to the Mortgage Loans involving a Sub-Servicer shall be deemed
to be between the Sub-Servicer and the Servicer alone and the Trustee and the
Certificateholders shall not be deemed parties thereto and shall have no claims,
rights, obligations, duties or liabilities with respect to any Sub-Servicer
except as set forth in Section 3.05.

                  SECTION 3.05. Assumption or Termination of Sub-Servicing
                                Agreement by Successor Servicer.

                                      -69-
<PAGE>

                  In connection with the assumption of the responsibilities,
duties and liabilities and of the authority, power and rights of the Servicer
hereunder by a successor Servicer (which may be the Trustee or the Master
Servicer) pursuant to Section 8.02, it is understood and agreed that the
Servicer's rights and obligations under any Sub-Servicing Agreement then in
force between the Servicer and a Sub-Servicer shall be assumed simultaneously by
such successor Servicer without act or deed on the part of such successor
Servicer; provided, however, that any successor Servicer may terminate the
Sub-Servicer.

                  The Servicer shall, upon the reasonable request of the Master
Servicer, but at the expense of the Servicer, deliver to the assuming party
documents and records relating to each Sub- Servicing Agreement and an
accounting of amounts collected and held by it and otherwise use its best
efforts to effect the orderly and efficient transfer of the Sub-Servicing
Agreements to the assuming party.

                  SECTION 3.06. Collection of Certain Mortgage Loan Payments.

                  The Servicer shall make reasonable efforts to collect all
payments called for under the terms and provisions of the Mortgage Loans, and
shall, to the extent such procedures shall be consistent with this Agreement and
Accepted Servicing Practices, follow such collection procedures as it would
follow with respect to mortgage loans comparable to the Mortgage Loans and held
for its own account. Consistent with the foregoing, the Servicer may in its
discretion (i) waive any late payment charge or, if applicable, penalty interest
or (ii) extend the due dates for the Monthly Payments due on a Mortgage Note for
a period of not greater than 180 days; provided that any extension pursuant to
this clause shall not affect the amortization schedule of any Mortgage Loan for
purposes of any computation hereunder. Notwithstanding the foregoing, in the
event that any Mortgage Loan is in default or, in the judgment of the Servicer,
such default is reasonably foreseeable, the Servicer, consistent with Accepted
Servicing Practices may waive, modify or vary any term of such Mortgage Loan
(including modifications that change the Mortgage Rate, forgive the payment of
principal or interest or extend the final maturity date of such Mortgage Loan),
accept payment from the related Mortgagor of an amount less than the Stated
Principal Balance in final satisfaction of such Mortgage Loan, or consent to the
postponement of strict compliance with any such term or otherwise grant
indulgence to any Mortgagor if in the Servicer's determination such waiver,
modification, postponement or indulgence is not materially adverse to the
interests of the Certificateholders (taking into account any estimated Realized
Loss that might result absent such action).

                  SECTION 3.07. Collection of Taxes, Assessments and Similar
                                Items; Servicing Accounts.

                  To the extent the terms of a Mortgage provide for Escrow
Payments, the Servicer shall establish and maintain one or more accounts (the
"Servicing Accounts"), into which all collections from the Mortgagors (or
related advances from Sub-Servicers) for the payment of taxes, assessments,
fire, flood, and hazard insurance premiums, and comparable items for the account
of the Mortgagors ("Escrow Payments") shall be deposited and retained. Servicing
Accounts shall be Eligible Accounts. The Servicer shall deposit in the Servicing
Accounts on a daily basis and in no event later than the second Business Day
after receipt, and retain therein, all Escrow Payments

                                      -70-
<PAGE>

collected on account of the Mortgage Loans, for the purpose of effecting the
timely payment of any such items as required under the terms of this Agreement.
Withdrawals of amounts from a Servicing Account may be made only to (i) effect
timely payment of taxes, assessments, fire, flood, and hazard insurance
premiums, and comparable items; (ii) reimburse the Servicer out of related
collections for any advances made pursuant to Section 3.01 (with respect to
taxes and assessments) and Section 3.11 (with respect to fire, flood and hazard
insurance); (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; or (v) clear and terminate the Servicing
Account at the termination of the Servicer's obligations and responsibilities in
respect of the Mortgage Loans under this Agreement in accordance with Article
IX. As part of its servicing duties, the Servicer shall pay to the Mortgagors
interest on funds in Servicing Accounts, to the extent required by law and, to
the extent that interest earned on funds in the Servicing Accounts is
insufficient, to pay such interest from its or their own funds, without any
reimbursement therefor. Notwithstanding the foregoing, the Servicer shall not be
obligated to collect Escrow Payments if the related Mortgage Loan does not
require such payments but the Servicer shall nevertheless be obligated to make
Servicing Advances as provided in Section 3.01 and Section 3.11. In the event
the Servicer shall deposit in the Servicing Accounts any amount not required to
be deposited therein, it may at any time withdraw such amount from the Servicing
Accounts, any provision to the contrary notwithstanding.

                  To the extent that a Mortgage does not provide for Escrow
Payments, the Servicer (i) shall determine whether any such payments are made by
the Mortgagor in a manner and at a time that is necessary to avoid the loss of
the Mortgaged Property due to a tax sale or the foreclosure as a result of a tax
lien and (ii) shall ensure that all insurance required to be maintained on the
Mortgaged Property pursuant to this Agreement is maintained. If any such payment
has not been made and the Servicer receives notice of a tax lien with respect to
the Mortgage Loan being imposed, the Servicer shall, promptly and to the extent
required to avoid loss of the Mortgaged Property, advance or cause to be
advanced funds necessary to discharge such lien on the Mortgaged Property. The
Servicer assumes full responsibility for the payment of all such bills and shall
effect payments of all such bills irrespective of the Mortgagor's faithful
performance in the payment of same or the making of the Escrow Payments and
shall make Servicing Advances to effect such payments subject to its
determination of recoverability.

                  SECTION 3.08. Collection Account and Distribution Account.

                  (a) On behalf of the Trust Fund, the Servicer shall establish
and maintain one or more accounts (such account or accounts, the "Collection
Account"), held in trust for the benefit of the Trustee and the
Certificateholders. On behalf of the Trust Fund, the Servicer shall deposit or
cause to be deposited in the Collection Account on a daily basis and in no event
later than two Business Days after receipt, as and when received or as otherwise
required hereunder, the following payments and collections received or made by
it on or subsequent to the Cut-off Date:

                           (i) all payments on account of principal, including
                  Principal Prepayments, on the Mortgage Loans;

                           (ii) all payments on account of interest (net of the
                  related Servicing Fee) on each Mortgage Loan;

                                      -71-
<PAGE>

                           (iii) all Insurance Proceeds and Liquidation Proceeds
                  (other than proceeds collected in respect of any particular
                  REO Property and amounts paid by the Servicer in connection
                  with a purchase of Mortgage Loans and REO Properties pursuant
                  to Section 9.01);

                           (iv) any amounts required to be deposited pursuant to
                  Section 3.10 in connection with any losses realized on
                  Permitted Investments with respect to funds held in the
                  Collection Account;

                           (v) any amounts required to be deposited by the
                  Servicer pursuant to the second paragraph of Section 3.11(a)
                  in respect of any blanket policy deductibles;

                           (vi) any Purchase Price or Substitution Shortfall
                  Amount delivered to the Servicer and all proceeds (net of
                  amounts payable or reimbursable to the Servicer, the Master
                  Servicer, the Trustee, the Custodian or the Securities
                  Administrator) of Mortgage Loans purchased in accordance with
                  Section 10.01 or pursuant to any other provision of this
                  Agreement; and

                           (vii) any Prepayment Charges or amounts required to
                  be deposited by the Servicer in connection with a breach of
                  its obligations under Section 3.01 with respect to the waiver
                  of Prepayment Charges or any amounts paid by the Seller in
                  respect of any waived Prepayment Charges as described in
                  Section 3.01.

                  The foregoing requirements for deposit in the Collection
Account shall be exclusive, it being understood and agreed that, without
limiting the generality of the foregoing, payments in the nature of late payment
charges, assumption fees or other similar fees need not be deposited by the
Servicer in the Collection Account. In the event the Servicer shall deposit in
the Collection Account any amount not required to be deposited therein, it may
at any time withdraw such amount from the Collection Account, any provision
herein to the contrary notwithstanding.

                  (b) On behalf of the Trust Fund, the Trustee shall establish
and maintain one or more accounts (such account or accounts, the "Distribution
Account"), held in trust for the benefit of the Trustee, the Trust Fund and the
Certificateholders. On behalf of the Trust Fund, the Servicer shall deliver to
the Trustee in immediately available funds for deposit in the Distribution
Account (i) on or before 3:00 p.m. New York time on the Servicer Remittance
Date, that portion of the Available Distribution Amount (calculated without
regard to the references in clause (2) of the definition thereof to amounts that
may be withdrawn from the Distribution Account) for the related Distribution
Date then on deposit in the Collection Account and the amount of all Prepayment
Charges collected by the Servicer in connection with the Principal Prepayment of
any of the Mortgage Loans (including any Servicer Prepayment Charge Payment
Amount) then on deposit in the Collection Account and the amount of any funds
reimbursable to an Advance Financing Person pursuant to Section 3.25, and (ii)
on each Business Day as of the commencement of which the balance on deposit in
the Collection Account exceeds $75,000 following any withdrawals pursuant to the
next succeeding sentence, the amount of such excess, but only if the Collection
Account constitutes an Eligible Account solely pursuant to clause (ii) of the
definition of "Eligible Account." If the balance on deposit in the Collection
Account exceeds $75,000 as of the commencement of

                                      -72-

business on any Business Day and the Collection Account constitutes an Eligible
Account solely pursuant to clause (ii) of the definition of "Eligible Account,"
the Servicer shall, on or before 5:00 p.m. New York time on such Business Day,
withdraw from the Collection Account any and all amounts payable or reimbursable
to the Depositor, the Servicer, the Trustee or the Seller pursuant to Section
3.09 and shall pay such amounts to the Persons entitled thereto.

                  (c) Funds in the Collection Account and the Distribution
Account may be invested in Permitted Investments in accordance with the
provisions set forth in Section 3.10. The Servicer shall give notice to the
Trustee and the Master Servicer of the location of the Collection Account
maintained by it when established and prior to any change thereof. The Trustee
shall give notice to the Servicer and the Depositor of the location of the
Distribution Account when established and prior to any change thereof.

                  (d) Funds held in the Collection Account at any time may be
delivered by the Servicer in immediately available funds to the Trustee for
deposit in the Distribution Account. In the event the Servicer shall deliver to
the Trustee for deposit in the Distribution Account any amount not required to
be deposited therein, it may at any time request that the Trustee withdraw such
amount from the Distribution Account and remit to it any such amount, any
provision herein to the contrary notwithstanding. In no event shall the Trustee
incur liability as a result of withdrawals from the Distribution Account at the
direction of the Servicer in accordance with the immediately preceding sentence.
In addition, the Servicer shall deliver to the Trustee no later than the
Servicer Remittance Date the amounts set forth in clauses (i) through (iv)
below:

                           (i) any P&I Advances, as required pursuant to Section
                  5.03;

                           (ii) any amounts required to be deposited pursuant to

                  Property;

                           (iii) any amounts to be paid in connection with a
                  purchase of Mortgage Loans and REO Properties pursuant to
                  Section 10.01; and

                           (iv) any amounts required to be deposited pursuant to
                  Section 3.22 in connection with any Prepayment Interest
                  Shortfalls.

                                Distribution Account.

                  pursuant to Section 3.08(b) or permitted to be so remitted
                  pursuant to the first sentence of Section 3.08(d);

                           (ii) subject to Section 3.13(d), to reimburse the

                  Servicing Fees) of Monthly Payments on Mortgage Loans with

                  Insurance Proceeds received with respect to such Mortgage
                  Loan;

                           (iv) to pay to the Servicer as servicing compensation
                  (in addition to the Servicing Fee) on the Servicer Remittance

                           (vi) to reimburse the Servicer (including any
                  successor Servicer) for any P&I Advance or Servicing Advance
                  previously made by it which the Servicer has determined to be

                           (viii) to reimburse the Servicer or the Trustee, as

                  SECTION 3.10. Investment of Funds in the Investment Accounts.

                           (a) The Servicer may direct, by means of written
directions (which may be standing directions), any depository institution
maintaining the Collection Account to invest the funds in the Collection Account
(for purposes of this Section 3.10, an "Investment Account") in one or more
Permitted Investments bearing interest or sold at a discount, and maturing,
unless payable on demand, (i) no later than the Business Day immediately
preceding the date on which such funds are required to be withdrawn from such
account pursuant to this Agreement, if a Person other than the Trustee is the
obligor thereon, and (ii) no later than the date on which such funds are
required to be withdrawn from such account pursuant to this Agreement, if the
Trustee is the obligor thereon. Amounts in the Distribution Account shall be
invested in Permitted Investments as directed in writing by the Master Servicer.
All such Permitted Investments shall be held to maturity, unless payable on
demand. Any investment of funds shall be made in the name of the Trustee (in its
capacity as such) or in the name of a nominee of the Trustee. The Trustee shall

subsection (b) below, the income thereon, and any certificate or other
instrument evidencing any such investment shall be delivered directly to the
Trustee or its agent, together with any document of transfer necessary to
transfer title to such investment to the Trustee or its nominee. In the event
amounts on deposit in the Collection Account are at any time invested in a
Permitted Investment payable on demand, the party with investment discretion
over such Investment Account shall:

                           (x) consistent with any notice required to be given
                  thereunder, demand that payment thereon be made on the last
                  day such Permitted Investment may

                                      -75-
<PAGE>

                  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

                           (y) demand payment of all amounts due thereunder
                  promptly upon determination by a Responsible Officer of the
                  Trustee that such Permitted Investment would not constitute a
                  Permitted Investment in respect of funds thereafter on deposit
                  in the Investment Account.

                           (b) All income and gain realized from the investment
of funds deposited in the Collection Account held by or on behalf of the
Servicer or the Trustee, shall be for the benefit of the Servicer and shall be
subject to its withdrawal in accordance with Section 3.09. The Servicer shall
deposit in the Collection Account the amount of any loss incurred in respect of
any such Permitted Investment made with funds in such account immediately upon
realization of such loss. All earnings and gain realized from the investment of
funds deposited in the Distribution Account shall be for the benefit of the
Master Servicer. The Master Servicer shall remit from its own funds for deposit
into the Distribution Account the amount of any loss incurred on Permitted
Investments in the Distribution Account.

                           (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, the Trustee may and, subject to Section 9.01 and
Section 9.02(v), shall, at the written direction of the Servicer, take such
action as may be appropriate to enforce such payment or performance, including
the institution and prosecution of appropriate proceedings.

                           (d) The Trustee, the Master Servicer or their
respective Affiliates are permitted to receive additional compensation that
could be deemed to be in the Trustee's or the Master Servicer's economic
self-interest for (i) serving as investment adviser, administrator, shareholder
servicing agent, custodian or sub-custodian with respect to certain of the
Permitted Investments, (ii) using Affiliates to effect transactions in certain
Permitted Investments and (iii) effecting transactions in certain Permitted
Investments. Such compensation shall not be considered an amount that is
reimbursable or payable to the Trustee or the Master Servicer pursuant to
Section 3.09 or 3.10 or otherwise payable in respect of Extraordinary Trust Fund
Expenses.

                  SECTION 3.11. Maintenance of Hazard Insurance and Errors and
                                Omissions and Fidelity Coverage.

                  (a) The terms of each Mortgage Note require the related
Mortgagor to maintain fire, flood and hazard insurance policies. To the extent
such policies are not maintained, the Servicer shall cause to be maintained for
each Mortgaged Property fire and hazard insurance with extended coverage as is
customary in the area where the Mortgaged Property is located in an amount which
is at least equal to the lesser of the current principal balance of such
Mortgage Loan and the amount necessary to compensate fully for any damage or
loss to the improvements which are a part of such property on a replacement cost
basis, in each case in an amount not less than such amount as is necessary to
avoid the application of any coinsurance clause contained in the related hazard
insurance policy. The Servicer shall also cause to be maintained fire and hazard
insurance on each

                                      -76-
<PAGE>

REO Property with extended coverage as is customary in the area where the
Mortgaged Property is located in an amount which is at least equal to the lesser
of (i) the maximum insurable value of the improvements which are a part of such
property and (ii) the outstanding principal balance of the related Mortgage Loan
at the time it became an REO Property. The Servicer will comply in the
performance of this Agreement with all reasonable rules and requirements of each
insurer under any such hazard policies. Any amounts to be collected by the
Servicer under any such policies (other than amounts to be applied to the
restoration or repair of the property subject to the related Mortgage or amounts
to be released to the Mortgagor in accordance with Accepted Servicing Practices,
subject to the terms and conditions of the related Mortgage and Mortgage Note)
shall be deposited in the Collection Account, subject to withdrawal pursuant to
Section 3.09, if received in respect of a Mortgage Loan, or in the REO Account,
subject to withdrawal pursuant to Section 3.21, if received in respect of an REO
Property. Any cost incurred by the Servicer in maintaining any such insurance
shall not, for the purpose of calculating distributions to Certificateholders,
be added to the unpaid principal balance of the related Mortgage Loan,
notwithstanding that the terms of such Mortgage Loan so permit. It is understood
and agreed that no earthquake or other additional insurance is to be required of
any Mortgagor other than pursuant to such applicable laws and regulations as
shall at any time be in force and as shall require such additional insurance. If
the Mortgaged Property or REO Property is at any time in an area identified in
the Federal Register by the Federal Emergency Management Agency as having
special flood hazards, the Servicer will cause to be maintained a flood
insurance policy in respect thereof. Such flood insurance shall be in an amount
equal to the lesser of (i) the unpaid principal balance of the related Mortgage
Loan and (ii) the maximum amount of such insurance available for the related
Mortgaged Property under the national flood insurance program (assuming that the
area in which such Mortgaged Property is located is participating in such
program).

                  In the event that the Servicer shall obtain and maintain a
blanket policy with an insurer having a General Policy Rating of B:VI or better
in Best's Key Rating Guide insuring against hazard losses on all of the Mortgage
Loans, it shall conclusively be deemed to have satisfied its obligations to
cause fire and hazard insurance to be maintained on the Mortgaged Properties, it
being understood and agreed that such policy may contain a deductible clause, in
which case the Servicer shall, in the event that there shall not have been
maintained on the related Mortgaged Property or REO Property a policy complying
with the first two sentences of this Section 3.11, and there shall have been one
or more losses which would have been covered by such policy, deposit to the
Collection Account from its own funds the amount not otherwise payable under the
blanket policy because of such deductible clause. In connection with its
activities as administrator and servicer of the Mortgage Loans, the Servicer
agrees to prepare and present, on behalf of itself, the Trustee, the Trust Fund
and the Certificateholders, claims under any such blanket policy in a timely
fashion in accordance with the terms of such policy.

                  (b) The Servicer shall keep in force during the term of this
Agreement a policy or policies of insurance covering errors and omissions for
failure in the performance of its respective obligations under this Agreement,
which policy or policies shall be in such form and amount that would meet the
requirements of Fannie Mae or Freddie Mac if it were the purchaser of the
Mortgage Loans, unless the Servicer, has obtained a waiver of such requirements
from Fannie Mae or Freddie Mac. The Servicer shall each also maintain a fidelity
bond in the form and amount that would meet the requirements of Fannie Mae or
Freddie Mac, unless the Servicer, has obtained a waiver of such

                                      -77-
<PAGE>

requirements from Fannie Mae or Freddie Mac. The Servicer shall be deemed to
have complied with this provision if an Affiliate of the Servicer, has such
errors and omissions and fidelity bond coverage and, by the terms of such
insurance policy or fidelity bond, the coverage afforded thereunder extends to
the Servicer. Any such errors and omissions policy and fidelity bond shall by
its terms not be cancelable without thirty days' prior written notice to the
Trustee.

                  SECTION 3.12. Enforcement of Due-on-Sale Clauses; Assumption
                                Agreements.

                  The Servicer shall, to the extent it has knowledge of any
conveyance of any Mortgaged Property by any Mortgagor (whether by absolute
conveyance or by contract of sale, and whether or not the Mortgagor remains or
is to remain liable under the Mortgage Note and/or the Mortgage), exercise its
rights to accelerate the maturity of such Mortgage Loan under the "due-on- sale"
clause, if any, applicable thereto; provided, however, that the Servicer shall
not exercise any such rights if prohibited by law from doing so. If the Servicer
reasonably believes it is unable under applicable law to enforce such
"due-on-sale" clause, or if any of the other conditions set forth in the proviso
to the preceding sentence apply, the Servicer shall enter into an assumption and
modification agreement from or with the person to whom such property has been
conveyed or is proposed to be conveyed, pursuant to which such person becomes
liable under the Mortgage Note and, to the extent permitted by applicable state
law, the Mortgagor remains liable thereon. The Servicer is also authorized to
enter into a substitution of liability agreement with such person, pursuant to
which the original Mortgagor is released from liability and such person is
substituted as the Mortgagor and becomes liable under the Mortgage Note,
provided that no such substitution shall be effective unless such person
satisfies the then current underwriting criteria of the Servicer for mortgage
loans similar to the Mortgage Loans. In connection with any assumption or
substitution, the Servicer shall apply such underwriting standards and follow
such practices and procedures as shall be normal and usual in its general
mortgage servicing activities and as it applies to other mortgage loans owned
solely by it. The Servicer shall not take or enter into any assumption and
modification agreement, however, unless (to the extent practicable in the
circumstances) it shall have received confirmation, in writing, of the continued
effectiveness of any applicable hazard insurance policy. Any fee collected by
the Servicer in respect of an assumption or substitution of liability agreement
will be retained by the Servicer as additional servicing compensation. In
connection with any such assumption, no material term of the Mortgage Note
(including but not limited to the related Mortgage Rate and the amount of the
Monthly Payment) may be amended or modified, except as otherwise required
pursuant to the terms thereof. The Servicer shall notify the Trustee (or the
Custodian) that any such substitution or assumption agreement has been completed
by forwarding to the Trustee the executed original of such substitution or
assumption agreement, which document shall be added to the related Mortgage File
and shall, for all purposes, be considered a part of such Mortgage File to the
same extent as all other documents and instruments constituting a part thereof.

                  Notwithstanding the foregoing paragraph or any other provision
of this Agreement, the Servicer shall not be deemed to be in default, breach or
any other violation of its obligations hereunder by reason of any assumption of
a Mortgage Loan by operation of law or by the terms of the Mortgage Note or any
assumption which the Servicer may be restricted by law from preventing, for any
reason whatever. For purposes of this Section 3.12, the term "assumption" is
deemed to also

                                      -78-
<PAGE>

include a sale (of the Mortgaged Property) subject to the Mortgage that is not
accompanied by an assumption or substitution of liability agreement.

                  SECTION 3.13. Realization Upon Defaulted Mortgage Loans.

                  (a) The Servicer shall use its best efforts, consistent with
         Accepted Servicing Practices, to foreclose upon or otherwise comparably
         convert the ownership of properties securing 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 pursuant
         to Section 3.06. The Servicer shall be responsible for all costs and
         expenses incurred by it in any such proceedings; provided, however,
         that such costs and expenses will be recoverable as Servicing Advances
         by the Servicer as contemplated in Sections 3.09 and 3.21. The
         foregoing is subject to the provision that, in any case in which a
         Mortgaged Property shall have suffered damage from an Uninsured Cause,
         the Servicer shall not be required to expend its own funds toward the
         restoration of such property unless it shall determine in its
         discretion that such restoration will increase the proceeds of
         liquidation of the related Mortgage Loan after reimbursement to itself
         for such expenses.

                  (b) Notwithstanding the foregoing provisions of this Section
         3.13 or any other provision of this Agreement, with respect to any
         Mortgage Loan as to which the Servicer has received actual notice of,
         or has actual knowledge of, the presence of any toxic or hazardous
         substance on the related Mortgaged Property, the Servicer shall not, on
         behalf of the Trust Fund, either (i) obtain title to such Mortgaged
         Property as a result of or in lieu of foreclosure or otherwise, or (ii)
         otherwise acquire possession of, or take any other action with respect
         to, such Mortgaged Property, if, as a result of any such action, the
         Trust Fund, the Trustee or the Certificateholders would 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
         the Comprehensive Environmental Response, Compensation and Liability
         Act of 1980, as amended from time to time, or any comparable law,
         unless the Servicer has also previously determined, based on its
         reasonable judgment and a prudent report prepared by an Independent
         Person who regularly conducts environmental audits using customary
         industry standards, that:

                  (1) such Mortgaged Property is in compliance with applicable
         environmental laws or, if not, that it would be in the best economic
         interest of the Trust Fund to take such actions as are necessary to
         bring the Mortgaged Property into compliance therewith; and

                  (2) there are no circumstances present at such Mortgaged
         Property relating to the use, management or disposal of any hazardous
         substances, hazardous materials, hazardous wastes or petroleum-based
         materials for which investigation, testing, monitoring, containment,
         clean-up or remediation could be required under any federal, state or
         local law or regulation, or that if any such materials are present for
         which such action could be required, that it would be in the best
         economic interest of the Trust Fund to take such actions with respect
         to the affected Mortgaged Property.

                  The cost of the environmental audit report contemplated by
this Section 3.13 shall be advanced by the Servicer, subject to the Servicer's
right to be reimbursed therefor from the Collection Account as provided in
Section 3.09(a)(ix), such right of reimbursement being prior to

                                      -79-
<PAGE>

the rights of Certificateholders to receive any amount in the Collection Account
received in respect of the affected Mortgage Loan or other Mortgage Loans.

                  If the Servicer determines, as described above, that it is in
the best economic interest of the Trust Fund to take such actions as are
necessary to bring any such Mortgaged Property into compliance with applicable
environmental laws, or to take such action with respect to the containment,
clean-up or remediation of hazardous substances, hazardous materials, hazardous
wastes, or petroleum-based materials affecting any such Mortgaged Property, then
the Servicer shall take such action as it deems to be in the best economic
interest of the Trust Fund. The cost of any such compliance, containment,
cleanup or remediation shall be advanced by the Servicer, subject to the
Servicer's right to be reimbursed therefor from the Collection Account as
provided in Sections 3.09(a)(iii) or 3.09(a)(ix), such right of reimbursement
being prior to the rights of Certificateholders to receive any amount in the
Collection Account received in respect of the affected Mortgage Loan or other
Mortgage Loans.

                  (c) The Servicer shall have the right to purchase from REMIC I
any defaulted Mortgage Loan that is 90 days or more delinquent, which the
Servicer determines in good faith will otherwise become subject to foreclosure
proceedings (evidence of such determination to be delivered in writing to the
Trustee, in form and substance satisfactory to the Servicer and the Trustee
prior to purchase), at a price equal to the Purchase Price. The Purchase Price
for any Mortgage Loan purchased hereunder shall be deposited in the Collection
Account, and the Trustee, upon receipt of written certification from the
Servicer of such deposit, shall release or cause to be released to the Servicer
the related Mortgage File and the Trustee shall execute and deliver such
instruments of transfer or assignment, in each case without recourse,
representation or warranty, as the Servicer shall furnish and as shall be
necessary to vest in the Servicer title to any Mortgage Loan released pursuant
hereto.

                  (d) Proceeds received in connection with any Final Recovery
Determination, as well as any recovery resulting from a partial collection of
Insurance Proceeds or Liquidation Proceeds, in respect of any Mortgage Loan,
will be applied in the following order of priority: first, to reimburse the
Servicer for any related unreimbursed Servicing Advances and P&I Advances,
pursuant to Section 3.09(a)(ii) or (a)(iii); second, to accrued and unpaid
interest on the Mortgage Loan, to the date of the Final Recovery Determination,
or to the Due Date prior to the Distribution Date on which such amounts are to
be distributed if not in connection with a Final Recovery Determination; and
third, as a recovery of principal of the Mortgage Loan. If the amount of the
recovery so allocated to interest is less than the full amount of accrued and
unpaid interest due on such Mortgage Loan, the amount of such recovery will be
allocated by the Servicer as follows: first, to unpaid Servicing Fees; and
second, to the balance of the interest then due and owing. The portion of the
recovery so allocated to unpaid Servicing Fees shall be reimbursed to the
Servicer pursuant to Section 3.09(a)(iii). The portion of the recovery allocated
to interest (net of unpaid Servicing Fees) and the portion of the recovery
allocated to principal of the Mortgage Loan shall be applied as follows: first,
to reimburse the Servicer for any related unreimbursed Advances in accordance
with Section 3.09(a)(ii) and any other amounts reimbursable to the Servicer
pursuant to Section 3.09, and second, as part of the amounts to be transferred
to the Distribution Account in accordance with Section 3.08(b).

                                      -80-

                  SECTION 3.14. Trustee to Cooperate; Release of Mortgage Files.

                  (a) Upon becoming aware of the payment in full of any Mortgage
Loan, or the receipt by the Servicer of a notification that payment in full has
been escrowed in a manner customary for such purposes for payment to
Certificateholders on the next Distribution Date, the Servicer will promptly
furnish to the Custodian, on behalf of the Trustee, two copies of a request for
release substantially in the form attached to the Custodial Agreement signed by
a Servicing Officer or in a mutually agreeable electronic format which will, in
lieu of a signature on its face, originate from a Servicing Officer (which
certification shall include a statement to the effect that all amounts received
in connection with such payment that are required to be deposited in the
Collection Account have been or will be so deposited) and shall request that the
Custodian, on behalf of the Trustee, deliver to the Servicer the related
Mortgage File. Upon receipt of such certification and request, the Custodian, on
behalf of the Trustee, shall promptly release the related Mortgage File to the
Servicer and the Trustee and Custodian shall have no further responsibility with
regard to such Mortgage File. Upon any such payment in full, the Servicer is
authorized, to give, as agent for the Trustee, as the mortgagee under the
Mortgage that secured the Mortgage Loan, an instrument of satisfaction (or
assignment of mortgage without recourse) regarding the Mortgaged Property
subject to the Mortgage, which instrument of satisfaction or assignment, as the
case may be, shall be delivered to the Person or Persons entitled thereto
against receipt therefor of such payment, it being understood and agreed that no
expenses incurred in connection with such instrument of satisfaction or
assignment, as the case may be, shall be chargeable to the Collection Account.

                  (b) From time to time and as appropriate for the servicing or
foreclosure of any Mortgage Loan, the Trustee shall execute such documents as
shall be prepared and furnished to the Trustee by the Servicer (in form
reasonably acceptable to the Trustee) and as are necessary to the prosecution of
any such proceedings. The Custodian, on behalf of the Trustee, shall, upon the
request of the Servicer, and delivery to the Custodian, on behalf of the
Trustee, of two copies of a request for release signed by a Servicing Officer
substantially in the form attached to the Custodial Agreement (or in a mutually
agreeable electronic format which will, in lieu of a signature on its face,
originate from a Servicing Officer), release the related Mortgage File held in
its possession or control to the Servicer. Such trust receipt shall obligate the
Servicer to return the Mortgage File to the Custodian on behalf of the Trustee,
when the need therefor by the Servicer no longer exists unless the Mortgage Loan
shall be liquidated, in which case, upon receipt of a certificate of a Servicing
Officer similar to that hereinabove specified, the Mortgage File shall be
released by the Custodian, on behalf of the Trustee, to the Servicer.

                  Notwithstanding the foregoing, in connection with a Principal
Prepayment in full of any Mortgage Loan, the Master Servicer may request release
of the related Mortgage File from the Custodian, in accordance with the
provisions of the Custodial Agreement, in the event the Servicer fails to do so.

                  Upon written certification of a Servicing Officer, the Trustee
shall execute and deliver to the Servicer, any court pleadings, requests for
trustee's sale or other documents necessary to the foreclosure or trustee's sale
in respect of a Mortgaged Property or to any legal action brought to obtain
judgment against any Mortgagor on the Mortgage Note or Mortgage or to obtain a
deficiency judgment, or to enforce any other remedies or rights provided by the
Mortgage Note or Mortgage or

                                      -81-
<PAGE>

otherwise available at law or in equity. Each such certification shall include a
request that such pleadings or documents be executed by the Trustee and a
statement 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. So long as no Servicing
Termination Event shall have occurred and be continuing, the Servicer shall have
the right to execute any and all such court pleadings, requests and other
documents as attorney-in-fact for, and on behalf of the Trustee.

                  SECTION 3.15. Servicing Compensation.

                  As compensation for the activities of the Servicer, hereunder,
the Servicer shall be entitled to the Servicing Fee with respect to each
Mortgage Loan payable solely from payments of interest in respect of such
Mortgage Loan, subject to Section 3.22. In addition, the Servicer shall be
entitled to recover unpaid Servicing Fees out of Insurance Proceeds or
Liquidation Proceeds to the extent permitted by Section 3.09(a)(iii) and out of
amounts derived from the operation and sale of an REO Property to the extent
permitted by Section 3.21. The right to receive the Servicing Fee may not be
transferred in whole or in part except in connection with the transfer of all of
the Servicer's responsibilities and obligations under this Agreement to the
extent permitted herein.

                  Additional servicing compensation in the form of assumption
fees, late payment charges and other miscellaneous fees (other than Prepayment
Charges) shall be retained by the Servicer only to the extent such fees or
charges are received by the Servicer. The Servicer shall also be entitled
pursuant to Section 3.09(a)(iv) to withdraw from the Collection Account and
pursuant to Section 3.21(b) to withdraw from any REO Account, as additional
servicing compensation, interest or other income earned on deposits therein,
subject to Section 3.10. The Servicer shall be required to pay all expenses
incurred by it in connection with its servicing activities hereunder and shall
not be entitled to reimbursement therefor except as specifically provided
herein.

                  SECTION 3.16. Reports to the Trustee; Collection Account
                                Statements.

                  Not later than fifteen days after each Distribution Date, the
Servicer shall forward to the Master Servicer, the Trustee and the Depositor a
statement prepared by the institution at which the Collection Account is
maintained setting forth the status of the Collection Account as of the close of
business on such Distribution Date and showing, for the period covered by such
statement, the aggregate amount of deposits into and withdrawals from the
Collection Account of each category of deposit specified in Section 3.08(a) and
each category of withdrawal specified in Section 3.09. Copies of such statement
shall be provided by the Trustee to any Certificateholder and to any Person
identified to the Trustee as a prospective transferee of a Certificate, upon
request at the expense of the requesting party, provided such statement is
delivered by the Servicer to the Trustee.

                  SECTION 3.17. Statement as to Compliance.

                  Not later than March 15th of each calendar year commencing in
2004, the Servicer shall deliver to the Trustee, the Master Servicer and the
Depositor an Officers' Certificate (upon which the Master Servicer can
conclusively rely in connection with its obligations under Section 5.06)
stating, as to each signatory thereof, that (i) a review of the activities of
the Servicer during the

                                      -82-
<PAGE>

preceding year and of performance under this Agreement has been made under such
officers' supervision and (ii) to the best of such officer's knowledge, based on
such review, the Servicer has fulfilled all of its obligations under this
Agreement throughout such year, or, if there has been a default in the
fulfillment of any such obligation, specifying each such default known to such
officer and the nature and status thereof. Copies of any such statement shall be
provided by the Trustee to any Certificateholder, upon request at the expense of
the requesting party, provided such statement is delivered by the Servicer to
the Trustee.

                  SECTION 3.18. Independent Public Accountants' Servicing
                                Report.

                  Not later than March 15th of each calendar year commencing in
2004, the Servicer, at its expense, shall cause a nationally recognized firm of
independent certified public accountants to furnish to the Servicer a report
stating that (i) it has obtained a letter of representation regarding certain
matters from the management of the Servicer which includes an assertion that the
Servicer has complied with certain minimum residential mortgage loan servicing
standards, identified in the Uniform Single Attestation Program for Mortgage
Bankers established by the Mortgage Bankers Association of America, with respect
to the servicing of residential mortgage loans during the most recently
completed fiscal year and (ii) on the basis of an examination conducted by such
firm in accordance with standards established by the American Institute of
Certified Public Accountants, such representation is fairly stated in all
material respects, subject to such exceptions and other qualifications that may
be appropriate. Immediately upon receipt of such report, the Servicer shall
furnish a copy of such report to the Master Servicer, the Trustee and each
Rating Agency. Copies of such statement shall be provided by the Trustee to any
Certificateholder upon request at the Servicer's expense, provided that such
statement is delivered by the Servicer to the Trustee.

                  SECTION 3.19 Annual Certification.

                  (a) The Servicer shall deliver to the Master Servicer, on or
before March 15 of each calendar year beginning March 15, 2004 (or, if any such
day is not a Business Day, the immediately preceding Business Day), or on any
alternative date reasonably specified by the Master Servicer upon thirty (30)
days written request, a certification in the form attached hereto as Exhibit C.
Such certification shall be signed by the senior officer in charge of servicing
of the Servicer. In addition, the Servicer shall provide such other information
with respect to the Mortgage Loans and the servicing and administration thereof
within the control of the Servicer which shall be required to enable the Master
Servicer to comply with the reporting requirements of the Securities and
Exchange Act of 1934, as amended pursuant to Section 5.06 hereof.

                  (b) The Servicer shall indemnify and hold harmless the Master
Servicer, the Trustee, the Depositor and their respective officers, directors,
agents and affiliates from and against any losses, damages, penalties, fines,
forfeitures, reasonable legal fees and related costs, judgments and other costs
and expenses arising out of or based upon a breach by the Servicer or any of its
officers, directors, agents or affiliates of its obligations under this Section
3.19 or the Servicer's negligence, bad faith or willful misconduct in connection
therewith. Such indemnity shall survive the termination or resignation of the
parties hereto or the termination of this Agreement. If the indemnification
provided for herein is unavailable or insufficient to hold harmless the Master
Servicer, the Trustee and the Depositor, then the Servicer agrees that it shall
contribute to the amount

                                      -83-
<PAGE>

paid or payable by the Master Servicer, the Trustee and the Depositor as a
result of the losses, claims, damages or liabilities of the Master Servicer, the
Trustee and the Depositor in such proportion as is appropriate to reflect the
relative fault of the Master Servicer, the Trustee and the Depositor on the one
hand and the Servicer on the other in connection with a breach of the Servicer's
obligations under this Section 3.19.

                  SECTION 3.20. Access to Certain Documentation.

                  The Servicer shall provide to the Office of Thrift
Supervision, the FDIC, and any other federal or state banking or insurance
regulatory authority that may exercise authority over any Certificate Owner,
access to the documentation regarding the Mortgage Loans required by applicable
laws and regulations. Such access shall be afforded without charge, but only
upon reasonable request and during normal business hours at the offices of the
Servicer designated by it. In addition, access to the documentation regarding
the Mortgage Loans will be provided to any Certificate Owner, the Trustee and to
any Person identified to the Servicer, as a prospective transferee of a
Certificate, upon reasonable request during normal business hours at the offices
of the Servicer designated by it at the expense of the Person requesting such
access.

                  SECTION 3.21. Title, Management and Disposition of REO
                                Property.

                  (a) The deed or certificate of sale of any REO Property shall
be taken in the name of the Trustee, or its nominee, on behalf of the Trust Fund
and for the benefit of the Certificateholders. The Servicer, on behalf of REMIC
I, shall either sell any REO Property by the close of the third calendar year
following the calendar year in which REMIC I acquires ownership of such REO
Property for purposes of Section 860(a)(8) of the Code or request from the
Internal Revenue Service, no later than 60 days before the day on which the
three-year grace period would otherwise expire an extension of the three-year
grace period, unless the Servicer had delivered to the Trustee an Opinion of
Counsel, addressed to the Trustee and the Depositor, to the effect that the
holding by REMIC I of such REO Property subsequent to three years after its
acquisition will not result in the imposition on any Trust REMIC created
hereunder of taxes on "prohibited transactions" thereof, as defined in Section
860F of the Code, or cause any Trust REMIC hereunder to fail to qualify as a
REMIC under Federal law at any time that any Certificates are outstanding. The
Servicer shall manage, conserve, protect and operate each REO Property for the
Certificateholders solely for the purpose of its prompt disposition and sale in
a manner which does not cause such REO Property to fail to qualify as
"foreclosure property" within the meaning of Section 860G(a)(8) of the Code or
result in the receipt by any Trust REMIC created hereunder of any "income from
non-permitted assets" within the meaning of Section 860F(a)(2)(B) of the Code,
or any "net income from foreclosure property" which is subject to taxation under
the REMIC Provisions.

                  (b) The Servicer shall segregate and hold all funds collected
and received in connection with the operation of any REO Property separate and
apart from its own funds and general assets and shall establish and maintain
with respect to REO Properties an account held in trust for the Trustee, on
behalf of the Trust Fund and for the benefit of the Certificateholders (the "REO
Account"), which shall be an Eligible Account. The Servicer shall be permitted
to allow the Collection Account to serve as the REO Account, subject to separate
ledgers for each REO Property.

                                      -84-
<PAGE>

The Servicer shall be entitled to retain or withdraw any interest income paid on
funds deposited in the REO Account.

                  (c) The Servicer shall have full power and authority, subject
         only to the specific requirements and prohibitions of this Agreement,
         to do any and all things in connection with any REO Property as are
         consistent with the manner in which the Servicer manages and operates
         similar property owned by the Servicer or any of its Affiliates, all on
         such terms and for such period as the Servicer deems to be in the best
         interests of Certificateholders. In connection therewith, the Servicer
         shall deposit, or cause to be deposited, on a daily basis in the REO
         Account all revenues received by it with respect to an REO Property and
         shall withdraw therefrom funds necessary for the proper operation,
         management and maintenance 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; and

                  (iii) all costs and expenses necessary to maintain such REO
         Property.

                  To the extent that amounts on deposit in the REO Account with
respect to an REO Property are insufficient for the purposes set forth in
clauses (i) through (iii) above with respect to such REO Property, the Servicer
shall advance from its own funds such amount as is necessary for such purposes
if, but only if, the Servicer would make such advances if the Servicer owned the
REO Property and if in the Servicer's judgment, the payment of such amounts will
be recoverable from the rental or sale of the REO Property.

                  Subject to compliance with applicable laws and regulations as
shall at any time be in force, and notwithstanding the foregoing, the Servicer,
on behalf of the Trust Fund, shall not:

                  (i) enter into, renew or extend any New Lease with respect to
         any REO Property, if the New Lease by its terms will give rise to any
         income that does not constitute Rents from Real Property;

                  (ii) permit any amount to be received or accrued under any New
         Lease other than amounts that will constitute Rents from Real Property;

                  (iii) authorize or permit any construction on any REO
         Property, other than the completion of a building or other improvement
         thereon, and then only if more than ten percent of the construction of
         such building or other improvement was completed before default on the
         related Mortgage Loan became imminent, all within the meaning of
         Section 856(e)(4)(B) of the Code; or

                  (iv) allow any Person to Directly Operate any REO Property on
         any date more than 90 days after its date of acquisition by the Trust
         Fund;

                                      -85-
<PAGE>

unless, in any such case, the Servicer has obtained an Opinion of Counsel,
provided to the Servicer and the Trustee, to the effect that such action will
not cause such REO Property to fail to qualify as "foreclosure property" within
the meaning of Section 860G(a)(8) of the Code at any time that it is held by
REMIC I, in which case the Servicer may take such actions as are specified in
such Opinion of Counsel.

                  The Servicer may 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 shall not be
         inconsistent herewith;

                  (ii) any such contract shall require, or shall be administered
         to require, that the Independent Contractor pay all costs and expenses
         incurred in connection with the operation and management of such REO
         Property, including those listed above and remit all related revenues
         (net of such costs and expenses) to the Servicer as soon as
         practicable, but in no event later than thirty days following the
         receipt thereof by such Independent Contractor;

                  (iii) none of the provisions of this Section 3.21(c) relating
         to any such contract or to actions taken through any such Independent
         Contractor shall be deemed to relieve the Servicer of any of its duties
         and obligations to the Trustee on behalf of the Trust Fund and for the
         benefit of the Certificateholders with respect to the operation and
         management of any such REO Property; and

                  (iv) the 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 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 Servicer by such
Independent Contractor, and nothing in this Agreement shall be deemed to limit
or modify such indemnification. The Servicer shall be solely liable for all fees
owed by it to any such Independent Contractor, irrespective of whether the
Servicer's compensation pursuant to Section 3.15 is sufficient to pay such fees.
Any such agreement shall include a provision that such agreement may be
immediately terminated by the Trustee (as successor Servicer) or any other
successor Servicer (including the Master Servicer) without fee, in the event the
Servicer shall for any reason, no longer be the Servicer (including termination
due to a Servicer Event of Default).

                  (d) In addition to the withdrawals permitted under Section
3.21(c), the Servicer may from time to time make withdrawals from the REO
Account for any REO Property: (i) to pay itself unpaid Servicing Fees in respect
of the related Mortgage Loan; and (ii) to reimburse itself or any Sub-Servicer
for unreimbursed Servicing Advances and Advances made in respect of such REO
Property or the related Mortgage Loan. On the Servicer Remittance Date, the
Servicer shall withdraw from each REO Account maintained by it and deposit into
the Distribution Account in accordance with Section 3.08(d)(ii), for
distribution on the related Distribution Date in accordance with Section

                                      -86-
<PAGE>

4.01, the income from the related REO Property received during the prior
calendar month, net of any withdrawals made pursuant to Section 3.21(c) or this
Section 3.21(d).

                  (e) Subject to the time constraints set forth in Section
3.21(a), each REO Disposition shall be carried out by the Servicer at such price
and upon such terms and conditions as the Servicer shall deem necessary or
advisable, as shall be normal and usual in accordance with Accepted Servicing
Practices.

                  (f) The proceeds from the REO Disposition, net of any amount
required by law to be remitted to the Mortgagor under the related Mortgage Loan
and net of any payment or reimbursement to the Servicer as provided above, shall
be deposited in the Distribution Account in accordance with Section 3.08(d)(ii)
on the Servicer Remittance Date in the month following the receipt thereof for
distribution on the related Distribution Date in accordance with Section 4.01.
Any REO Disposition shall be for cash only (unless changes in the REMIC
Provisions made subsequent to the Startup Day allow a sale for other
consideration).

                  (g) The Servicer shall file information returns (and shall
provide a certification of a Servicing Officer to the Master Servicer that such
filings have been made) with respect to the receipt of mortgage interest
received in a trade or business, reports of foreclosures and abandonments of any
Mortgaged Property and cancellation of indebtedness income with respect to any
Mortgaged Property as required by Sections 6050H, 6050J and 6050P of the Code,
respectively. Such reports shall be in form and substance sufficient to meet the
reporting requirements imposed by such Sections 6050H, 6050J and 6050P of the
Code.

                  SECTION 3.22. Obligations of the Servicer in Respect of
                                Prepayment Interest Shortfalls; Relief Act
                                Interest Shortfalls.

                  The Servicer shall deliver to the Trustee for deposit into the
Distribution Account on or before 5:00 p.m. New York time on the Servicer
Remittance Date from its own funds an amount equal to the lesser of (i) the
aggregate of the Prepayment Interest Shortfalls attributable to prepayments in
full for the related Distribution Date resulting solely from voluntary Principal
Prepayments received by the Servicer during the related Prepayment Period and
(ii) 50% of its aggregate Servicing Fee for the most recently ended Prepayment
Period. The Servicer shall not have the right to reimbursement for any amounts
remitted to the Trustee in respect of this Section 3.22. The Servicer shall not
be obligated to pay the amounts set forth in this Section 3.22 with respect to
shortfalls resulting from the application of the Relief Act.

                  SECTION 3.23. Obligations of the Servicer in Respect of
                                Mortgage Rates and Monthly Payments.

                  In the event that a shortfall in any collection on or
liability with respect to any Mortgage Loan results from or is attributable to
adjustments to Mortgage Rates, Monthly Payments or Stated Principal Balances
that were made by the Servicer in a manner not consistent with the terms of the
related Mortgage Note and this Agreement, the Servicer, upon discovery or
receipt of notice thereof, immediately shall deliver to the Trustee for deposit
in the Distribution Account from its own funds the amount of any such shortfall
and shall indemnify and hold harmless the Trust

                                      -87-
<PAGE>

Fund, the Trustee, the Depositor and any successor Servicer in respect of any
such liability. Such indemnities shall survive the termination or discharge of
this Agreement.

                  SECTION 3.24. Reserve Fund.

                  (a) No later than the Closing Date, the Trustee shall
establish and maintain a separate, segregated trust account titled, "Reserve
Fund, JPMorgan Chase Bank, in trust for the registered holders of ACE Securities
Corp. Home Equity Loan Trust, Series 2003-FM1, Asset Backed Pass-Through
Certificates." On the Closing Date, the Depositor will deposit, or cause to be
deposited, into the Reserve Fund $1,000. In addition, the amount deposited in
the Reserve Fund shall be increased by any payments received by the Trustee
under the Cap Contracts and deposited into Reserve Fund the for the benefit of
the Class A-1 Certificates and Class A-2 Certificates.

                  (b) On each Distribution Date as to which there is a Net WAC
Rate Carryover Amount payable to the Class A Certificates or the Mezzanine
Certificates, the Trustee will deposit, based on the instructions received by it
from the Securities Administrator, into the Reserve Fund the amounts described
in Section 5.01(a)(7)(xv), rather than distributing such amounts to the Class CE
Certificateholders. On each such Distribution Date, the Trustee shall hold all
such amounts for the benefit of the Holders of the Class A Certificates and the
Mezzanine Certificates, and will distribute such amounts to the Holders of the
Class A Certificates and the Mezzanine Certificates in the amounts and
priorities set forth in Section 5.01(a). If no Net WAC Rate Carryover Amounts
are payable on a Distribution Date, the Trustee shall deposit, based on the
instructions received by it from the Securities Administrator, into the Reserve
Fund on behalf of the Class CE Certificateholders, from amounts otherwise
distributable to the Class CE Certificateholders, an amount such that when added
to other amounts already on deposit in the Reserve Fund, the aggregate amount on
deposit therein is equal to $1,000.

                  (c) For federal and state income tax purposes, the Class CE
Certificateholders will be deemed to be the owners of the Reserve Fund and all
amounts deposited into the Reserve Fund (other than the initial deposit therein
of $1,000) shall be treated as amounts distributed by REMIC III to the Holders
of the Class CE Certificates. Upon the termination of the Trust Fund, or the
payment in full of the Class A Certificates and the Mezzanine Certificates, all
amounts remaining on deposit in the Reserve Fund will be released by the Trust
Fund and distributed to the Class CE Certificateholders or their designees. The
Reserve Fund will be part of the Trust Fund but not part of any REMIC and any
payments to the Holders of the Class A Certificates or the Mezzanine
Certificates of Net WAC Rate Carryover Amounts will not be payments with respect
to a "regular interest" in a REMIC within the meaning of Code Section
860(G)(a)(1).

                  (d) By accepting a Class CE Certificate, each Class CE
Certificateholder hereby agrees that the Trustee will deposit into the Reserve
Fund the amounts described above on each Distribution Date rather than
distributing such amounts to the Class CE Certificateholders. By accepting a
Class CE Certificate, each Class CE Certificateholder further agrees that its
agreement to such action by the Trustee is given for good and valuable
consideration, the receipt and sufficiency of which is acknowledged by such
acceptance.

                                      -88-
<PAGE>

                  (e) At the direction of the Holders of a majority in
Percentage Interest in the Class CE Certificates, the Trustee shall direct any
depository institution maintaining the Reserve Fund to invest the funds in such
account in one or more Permitted Investments bearing interest or sold at a
discount, and maturing, unless payable on demand, (i) no later than the Business
Day immediately preceding the date on which such funds are required to be
withdrawn from such account pursuant to this Agreement, if a Person other than
the Trustee or an Affiliate manages or advises such investment, and (ii) no
later than the date on which such funds are required to be withdrawn from such
account pursuant to this Agreement, if the Trustee or an Affiliate manages or
advises such investment. The Trustee shall invest amounts on deposit in the
Reserve Fund in JPMorgan Prime Money Market Fund. All income and gain earned
upon such investment shall be deposited into the Reserve Fund. In no event shall
the Trustee be liable for any investments made pursuant to this clause (e).

                  (f) For federal tax return and information reporting, the
right of the Class A Certificateholders and the Mezzanine Certificateholders to
receive payments from the Reserve Fund in respect of any Net WAC Rate Carryover
Amount shall be assigned a value of zero.

                  SECTION 3.25. Advance Facility.

                  (a) The Servicer is hereby authorized to enter into a
financing or other facility (any such arrangement, an "Advance Facility"), the
documentation for which complies with Section 3.25(e) below, under which (1) the
Servicer assigns or pledges its rights under this Agreement to be reimbursed for
any or all P&I Advances and/or Servicing Advances to (i) a Person, which may be
a special-purpose bankruptcy-remote entity (an "SPV"), (ii) a Person, which may
simultaneously assign or pledge such rights to an SPV or (iii) a lender (a
"Lender"), which, in the case of any Person or SPV of the type described in
either of the preceding clauses (i) or (ii), may directly or through other
assignees and/or pledgees, assign or pledge such rights to a Person, which may
include a trustee acting on behalf of holders of debt instruments (any such
Person or any such Lender, an "Advance Financing Person"), and/or (2) an Advance
Financing Person agrees to fund all the P&I Advances and/or Servicing Advances
required to be made by the Servicer pursuant to this Agreement. No consent of
the Trustee, Certificateholders or any other party shall be required before the
Servicer may enter into an Advance Facility nor shall the Trustee or the
Certificateholders be a third party beneficiary of any obligation of an Advance
Financing Person to the Servicer. Notwithstanding the existence of any Advance
Facility under which an Advance Financing Person agrees to fund P&I Advances
and/or Servicing Advances, (A) the Servicer (i) shall remain obligated pursuant
to this Agreement to make P&I Advances and/or Servicing Advances pursuant to and
as required by this Agreement and (ii) shall not be relieved of such obligations
by virtue of such Advance Facility and (B) neither the Advance Financing Person
nor any Servicer's Assignee (as hereinafter defined) shall have any right to
proceed against or otherwise contact any Mortgagor for the purpose of collecting
any payment that may be due with respect to any related Mortgage Loan or
enforcing any covenant of such Mortgagor under the related Mortgage Loan
documents.

                  (b) If the Servicer enters into an Advance Facility, the
Servicer and the related Advance Financing Person shall deliver to the Trustee
at the address set forth in Section 12.05 a written notice (an "Advance Facility
Notice"), stating (a) the identity of the Advance Financing Person and (b) the
identity of the Person (the "Servicer's Assignee") that will, subject to Section

                                      -89-
<PAGE>

3.25(c), have the right to receive amounts available from the Collection Account
pursuant to Section 3.09(a) to reimburse previously unreimbursed P&I Advances
and/or Servicing Advances ("Advance Reimbursement Amounts"). Advance
Reimbursement Amounts (i) shall consist solely of amounts in respect of P&I
Advances and/or Servicing Advances for which the Servicer would be permitted to
reimburse itself in accordance with Section 3.09(a), assuming the Servicer had
made the related P&I Advance(s) and/or Servicing Advance(s) and (ii) shall not
consist of amounts payable to a successor Servicer in accordance with Section
3.09(a) to the extent permitted under Section 3.25(d).

                  (c) Notwithstanding the existence of an Advance Facility, the
Servicer, on behalf of the Advance Financing Person and the Servicer's Assignee,
shall be entitled to receive reimbursements of P&I Advances and/or Servicing
Advances in accordance with Section 3.09(a), which entitlement may be terminated
by the Advance Financing Person identified in the Advance Facility Notice
pursuant to a written notice to the Trustee, the Master Servicer and the
Servicer in the manner set forth in Section 12.05. Upon receipt of such written
notice, the Servicer shall no longer be entitled to receive reimbursement for
any Advance Reimbursement Amounts and the Servicer's Assignee shall immediately
have the right to receive from the Collection Account all Advance Reimbursement
Amounts. Notwithstanding the foregoing, a Servicer's Assignee shall only be
entitled to reimbursement of Advance Reimbursement Amounts from the Collection
Account pursuant to Section 3.09(a) to the extent of and from the funds that the
Servicer would have been entitled to reimbursement hereunder and shall not
otherwise be entitled to receive amounts designated for distribution to
Certificateholders. None of the Trustee or the Certificateholders shall have any
right to, or otherwise be entitled to, receive any amounts which constitute
Advance Reimbursement Amounts. An Advance Facility may be terminated by the
joint written direction of the Servicer and the related Advance Financing
Person. Written notice of such termination shall be delivered to the Trustee and
the Master Servicer in the manner set forth in Section 12.05 hereof. None of the
Depositor, the Master Servicer or the Trustee shall, as a result of the
existence of any Advance Facility, have any additional duty or liability with
respect to the calculation or payment of any Advance Reimbursement Amount, nor,
as a result of the existence of any Advance Facility, shall the Depositor, the
Master Servicer or the Trustee have any additional responsibility to track or
monitor the administration of the Advance Facility or the payment of Advance
Reimbursement Amounts to the Servicer's Assignee. The Servicer shall indemnify
the Depositor, the Trustee, the Master Servicer, any successor Servicer and the
Trust Fund for any claim, loss, liability or damage resulting from any claim by
the related Advance Financing Person or the Servicer's Assignee, except to the
extent that such claim, loss, liability or damage resulted from or arose out of
the gross negligence, recklessness or willful misconduct on the part of the
Depositor, the Trustee, the Master Servicer or any successor Servicer, as the
case may be, or the breach of any obligations under this Agreement by the
successor Servicer, the Master Servicer or the Trustee, as the case may be. The
Servicer shall maintain and provide to any successor Servicer and, upon request,
the Trustee and the Master Servicer a detailed accounting on a loan-by-loan
basis as to amounts advanced by, pledged or assigned to, and reimbursed to any
Advance Financing Person. The successor Servicer shall be entitled to rely on
any such information provided by the predecessor Servicer, and the successor
Servicer (including the Trustee or the Master Servicer) shall not be liable for
any errors in such information.

                  (d) As between a predecessor Servicer and its Advance
Financing Person, on the one hand, and a successor Servicer and its Advance
Financing Person, if any, on the other hand,

                                      -90-
<PAGE>

Advance Reimbursement Amounts on a loan-by-loan basis with respect to each
Mortgage Loan as to which an Advance and/or Servicing Advance shall have been
made and be outstanding shall be allocated on a "first-in, first out" basis. In
the event the Servicer's Assignee shall have received some or all of an Advance
Reimbursement Amount related to Advances and/or Servicing Advances that were
made by a Person other than such predecessor Servicer or its related Advance
Financing Person in error, then such Servicer's Assignee shall be required to
remit any portion of such Advance Reimbursement Amount to each Person entitled
to such portion of such Advance Reimbursement Amount. Without limiting the
generality of the foregoing, the Servicer shall remain entitled to be reimbursed
by the Advance Financing Person for all Advances and/or Servicing Advances
funded by the Servicer to the extent the related Advance Reimbursement Amounts
have not been assigned or pledged to such Advance Financing Person or Servicer's
Assignee.

                  (e) For purposes of any Officer's Certificate of the Servicer
made pursuant to Section 4.03(d), any Nonrecoverable P&I Advance or
Nonrecoverable Servicing Advance referred to therein may have been made by such
Servicer or any predecessor Servicer. In making its determination that any P&I
Advance or Servicing Advance theretofore made has become a Nonrecoverable P&I
Advance or Nonrecoverable Servicing Advance, as applicable, the Servicer shall
apply the same criteria in making such determination regardless of whether such
P&I Advance or Servicing Advance shall have been made by the Servicer or any
predecessor Servicer.

                  (f) Any amendment to this Section 3.25 or to any other
provision of this Agreement that may be necessary or appropriate to effect the
terms of an Advance Facility as described generally in this Section 3.25, may be
entered into by the Trustee, the Depositor and the Servicer without the consent
of any Certificateholder, provided such amendment complies with Section 12.01.
All reasonable costs and expenses (including attorneys' fees and disbursements)
of each party hereto of any such amendment shall be borne solely by the Servicer
without reimbursement from the Trust Fund. The parties hereto hereby acknowledge
and agree that: (a) the P&I Advances and/or Servicing Advances financed by
and/or pledged to an Advance Financing Person under any Advance Facility are
obligations owed to the Servicer payable only from the cash flows and proceeds

                       ADMINISTRATION AND MASTER SERVICING
                  OF THE MORTGAGE LOANS BY THE MASTER SERVICER

                  SECTION 4.01. Master Servicer.

                  The Master Servicer shall supervise, monitor and oversee the
obligation of the Servicer to service and administer the Mortgage Loans in
accordance with the terms of the Agreement and shall have full power and
authority to do any and all things which it may deem necessary or desirable in
connection with such master servicing and administration. In performing its
obligations hereunder, the Master Servicer shall act in a manner consistent with
Accepted Master Servicing Practices. Furthermore, the Master Servicer shall
oversee and consult with the Servicer as necessary from time-to-time to carry
out the Master Servicer's obligations hereunder, shall receive, review and
evaluate all reports, information and other data provided to the Master Servicer
by the Servicer and shall cause the Servicer to perform and observe the
covenants, obligations and conditions to be performed or observed by the
Servicer under this Agreement. The Master Servicer shall independently and
separately monitor the Servicer's servicing activities with respect to each
related Mortgage Loan, reconcile the results of such monitoring with such
information provided in the previous sentence on a monthly basis and coordinate
corrective adjustments to the Servicer's and Master Servicer's records, and
based on such reconciled and corrected information, prepare the statements
specified in Section 5.03 and any other information and statements required to
be provided by the Master Servicer hereunder. The Master Servicer shall
reconcile the results of its Mortgage Loan monitoring with the actual
remittances of the Servicer to the Distribution Account pursuant to the terms
hereof based on information provided to the Master Servicer by the Trustee
pursuant to the fourth paragraph of Section 9.01.

                  The Trustee shall furnish the Servicer and the Master Servicer
with any limited powers of attorney and other documents in form as provided to
it necessary or appropriate to enable the Servicer and the Master Servicer to
service and administer the related Mortgage Loans and REO Property. The Trustee
shall have no responsibility for any action of the Master Servicer or any
Servicer pursuant to any such limited power of attorney and shall be indemnified
by the Master Servicer or the Servicer, as applicable, for any cost, liability
or expense incurred by the Trustee in connection with such Person's use or
misuse of any such power of attorney.

                  The Trustee, the Custodian and the Securities Administrator
shall provide access to the records and documentation in possession of the
Trustee, the Custodian or the Securities Administrator regarding the related
Mortgage Loans and REO Property and the servicing thereof to the
Certificateholders, the FDIC, and the supervisory agents and examiners of the
FDIC, such access being afforded only upon reasonable prior written request and
during normal business hours at the office of the Trustee, the Custodian or the
Securities Administrator; provided, however, that, unless otherwise required by
law, none of the Trustee, the Custodian or the Securities Administrator shall be
required to provide access to such records and documentation if the provision
thereof would violate the legal right to privacy of any Mortgagor. The Trustee,
the Custodian and the Securities Administrator shall allow representatives of
the above entities to photocopy any of the records and

                                      -93-

covers the Trustee's, the Custodian's or the Securities Administrator's actual
costs.

Master Servicer upon request any court pleadings, requests for trustee's sale or
other documents necessary or desirable to (i) the foreclosure or trustee's sale
with respect to a Mortgaged Property; (ii) any legal action brought to obtain
judgment against any Mortgagor on the Mortgage Note or any other Mortgage Loan
Document; (iii) obtain a deficiency judgment against the Mortgagor; or (iv)

Mortgage Loan Document or otherwise available at law or equity.

                  SECTION 4.02. REMIC-Related Covenants.

                  For as long as each REMIC shall exist, the Trustee and the
Securities Administrator shall act in accordance herewith to treat such REMIC as
a REMIC, and the Trustee and the Securities Administrator shall comply with any
directions of the Seller, the Servicer or the Master Servicer to assure such
continuing treatment. In particular, the Trustee shall not (a) sell or permit
the sale of all or any portion of the Mortgage Loans or of any investment of
deposits in an Account unless such sale is as a result of a repurchase of the
Mortgage Loans pursuant to this Agreement or the Trustee has received a REMIC
Opinion prepared at the expense of the Trust Fund; and (b) other than with
respect to a substitution pursuant to the Mortgage Loan Purchase Agreements or
Section 2.03 of this Agreement, as applicable, accept any contribution to any
REMIC after the Startup Day without receipt of a Opinion of Counsel stating that
such contribution will not result in an Adverse REMIC Event as deferred in
Section 11.01(f).

                  SECTION 4.03. Monitoring of Servicer.

                  (a) The Master Servicer shall be responsible for monitoring
the compliance by the Servicer with its duties under this Agreement. In the
review of the Servicer's activities, the Master Servicer may rely upon an
officer's certificate of the Servicer with regard to the Servicer's compliance
with the terms of this Agreement. In the event that the Master Servicer, in its
judgment, determines that the Servicer should be terminated in accordance with
the terms hereof, or that a notice should be sent pursuant to the terms hereof
with respect to the occurrence of an event that, unless cured, would constitute
an Event of Default, the Master Servicer shall notify the Seller and the Trustee
thereof and the Master Servicer shall issue such notice or take such other
action as it deems appropriate.

                  (b) The Master Servicer, for the benefit of the Trustee and
the Certificateholders, shall enforce the obligations of the Servicer under this
Agreement, and shall, in the event that the Servicer fails to perform its
obligations in accordance with this Agreement, subject to the preceding
paragraph and Article VIII, cause the Trustee to terminate the rights and
obligations of the Servicer hereunder in accordance with the provisions of
Article VIII. Such enforcement, including, without limitation, 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 good faith business judgment, would require were it the owner
of the related Mortgage Loans. The Master Servicer shall pay the costs of such
enforcement at its own expense, provided that the Master

                                      -94-
<PAGE>

Servicer shall not be required to prosecute or defend any legal action except to
the extent that the Master Servicer shall have received reasonable indemnity for
its costs and expenses in pursuing such action.

                  (c) To the extent that the costs and expenses of the Master
Servicer related to the termination of the Servicer, appointment of a successor
Servicer or the transfer and assumption of the servicing by the Master Servicer
(including, without limitation, (i) all legal costs and expenses and all due
diligence costs and expenses associated with an evaluation of the potential
termination of the Servicer as a result of a Servicer Event of Default and (ii)
all costs and expenses associated with the complete transfer of servicing,
including all servicing files and all servicing data and the completion,
correction or manipulation of such servicing data as may be required by the
successor servicer to correct any errors or insufficiencies in the servicing
data or otherwise to enable the successor servicer to service the Mortgage Loans
in accordance with this Agreement) are not fully and timely reimbursed by the
terminated Servicer, the Master Servicer shall be entitled to reimbursement of
such costs and expenses from the Distribution Account.

                  (d) The Master Servicer shall require the Servicer to comply
with the remittance requirements and other obligations set forth in this
Agreement.

                  (e) If the Master Servicer acts as successor Servicer, it will
not assume liability for the representations and warranties of the terminated
Servicer.

                  SECTION 4.04. Fidelity Bond.

                  The Master Servicer, at its expense, shall maintain in effect
a blanket fidelity bond and an errors and omissions insurance policy, affording
coverage with respect to all directors, officers, employees and other Persons
acting on such Master Servicer's behalf, and covering errors and omissions in
the performance of the Master Servicer's obligations hereunder. The errors and
omissions insurance policy and the fidelity bond shall be in such form and
amount generally acceptable for entities serving as master servicers or
trustees.

                  SECTION 4.05. Power to Act; Procedures.

                  The Master Servicer shall master service the Mortgage Loans
and shall have full power and authority, subject to the REMIC Provisions and the
provisions of Article XI, to do any and all things that it may deem necessary or
desirable in connection with the master servicing and administration of the
Mortgage Loans, including but not limited to the power and authority (i) to
execute and deliver, on behalf of the Certificateholders and the Trustee,
customary consents or waivers and other instruments and documents, (ii) to
consent to transfers of any Mortgaged Property and assumptions of the Mortgage
Notes and related Mortgages, (iii) to collect any Insurance Proceeds and
Liquidation Proceeds, and (iv) to effectuate foreclosure or other conversion of
the ownership of the Mortgaged Property securing any Mortgage Loan, in each
case, in accordance with the provisions of this Agreement; provided, however,
that the Master Servicer shall not (and, consistent with its responsibilities
under Section 4.03, shall not permit the Servicer to) knowingly or intentionally
take any action, or fail to take (or fail to cause to be taken) any action
reasonably within its control and the scope of duties more specifically set
forth herein, that, under the REMIC

                                      -95-
<PAGE>

Provisions, if taken or not taken, as the case may be, would cause REMIC I,
REMIC II or REMIC III to fail to qualify as a REMIC or result in the imposition
of a tax upon the Trust Fund (including but not limited to the tax on prohibited
transactions as defined in Section 860F(a)(2) of the Code and the tax on
contributions to a REMIC set forth in Section 860G(d) of the Code) unless the
Master Servicer has received an Opinion of Counsel (but not at the expense of
the Master Servicer) to the effect that the contemplated action will not would
cause REMIC I, REMIC II or REMIC III to fail to qualify as a REMIC or result in
the imposition of a tax upon REMIC I, REMIC II or REMIC III, as the case may be.
The Trustee shall furnish the Master Servicer, upon written request from a
Servicing Officer, with any powers of attorney empowering the Master Servicer or
the Servicer to execute and deliver instruments of satisfaction or cancellation,
or of partial or full release or discharge, and to foreclose upon or otherwise
liquidate Mortgaged Property, and to appeal, prosecute or defend in any court
action relating to the Mortgage Loans or the Mortgaged Property, in accordance
with this Agreement, and the Trustee shall execute and deliver such other
documents, as the Master Servicer or the Servicer may request, to enable the
Master Servicer to master service and administer the Mortgage Loans and carry
out its duties hereunder, in each case in accordance with Accepted Master
Servicing Practices (and the Trustee shall have no liability for misuse of any
such powers of attorney by the Master Servicer or the Servicer and shall be
indemnified by the Master Servicer or the Servicer, as applicable, for any cost,
liability or expense incurred by the Trustee in connection with such Person's
use or misuse of any such power of attorney). If the Master Servicer or the
Trustee has been advised that it is likely that the laws of the state in which
action is to be taken prohibit such action if taken in the name of the Trustee
or that the Trustee would be adversely affected under the "doing business" or
tax laws of such state if such action is taken in its name, the Master Servicer
shall join with the Trustee in the appointment of a co-trustee pursuant to
Section 9.10. In the performance of its duties hereunder, the Master Servicer
shall be an independent contractor and shall not, except in those instances
where it is taking action in the name of the Trustee, be deemed to be the agent
of the Trustee.

                  SECTION 4.06. Due-on-Sale Clauses; Assumption Agreements.

                  To the extent Mortgage Loans contain enforceable due-on-sale
clauses, the Master Servicer shall cause the Servicer to enforce such clauses in
accordance with this Agreement. If applicable law prohibits the enforcement of a
due-on-sale clause or such clause is otherwise not enforced in accordance with
this Agreement, and, as a consequence, a Mortgage Loan is assumed, the original
Mortgagor may be released from liability in accordance with this Agreement.

                  SECTION 4.07. Reserved.

                  SECTION 4.08. Documents, Records and Funds in Possession of

in respect of any Mortgage Loan or which otherwise are collected by the Master
Servicer as Liquidation Proceeds or Insurance Proceeds in respect of any
Mortgage Loan shall be remitted to the Trustee for deposit in the Distribution
Account. The Master Servicer shall, and shall

                                      -96-

cause the Servicer to, provide access to information and documentation regarding
the Mortgage Loans to the Trustee, its agents and accountants at any time upon
reasonable request and during normal business hours, and to Certificateholders
that are savings and loan associations, banks or insurance companies, the Office
of Thrift Supervision, the FDIC and the supervisory agents and examiners of such
Office and Corporation or examiners of any other federal or state banking or
insurance regulatory authority if so required by applicable regulations of the
Office of Thrift Supervision or other regulatory authority, such access to be
afforded without charge but only upon reasonable request in writing and during
normal business hours at the offices of the Master Servicer designated by it. In
fulfilling such a request the Master Servicer shall not be responsible for
determining the sufficiency of such information.

                  (b) All Mortgage Files and funds collected or held by, or
under the control of, the Master Servicer, in respect of any Mortgage Loans,
whether from the collection of principal and interest payments or from
Liquidation Proceeds or Insurance Proceeds, shall be remitted to the Trustee for
deposit in the Distribution Account.

                  SECTION 4.09. Standard Hazard Insurance and Flood Insurance
                                Policies.

understood and agreed that such insurance shall be with insurers meeting the
eligibility requirements set forth in Section 3.11 and that no earthquake or
other additional insurance is to be required of any Mortgagor or to be
maintained on property acquired in respect of a defaulted loan, other than
pursuant to such applicable laws and regulations as shall at any time be in
force and as shall require such additional insurance.

                  SECTION 4.10. Presentment of Claims and Collection of
                                Proceeds.

                  The Master Servicer shall enforce the Servicer's obligations
under this Agreement to, prepare and present on behalf of the Trustee and the

insured's claim) as shall be necessary to realize recovery under such policies.
Any proceeds disbursed to the Master Servicer in respect of such policies, bonds
or contracts shall be promptly remitted to the Trustee for deposit in the
Distribution Account upon receipt, except that any amounts realized that are to
be applied to the repair or restoration of the related Mortgaged Property as a
condition precedent to the presentation of claims on the related Mortgage Loan
to the insurer under any applicable insurance policy need not be so or remitted.

                  SECTION 4.11. Maintenance of the Primary Mortgage Insurance
                                Policies.

                  (a) The Master Servicer shall not take, or permit the Servicer
to take (to the extent such action is prohibited by this Agreement), any action
that would result in noncoverage under any primary mortgage insurance policy of
any loss which, but for the actions of the Master Servicer or the Servicer,
would have been covered thereunder. The Master Servicer shall use its best
reasonable efforts to cause the Servicer to keep in force and effect (to the
extent that the Mortgage Loan requires

                                      -97-
<PAGE>

the Mortgagor to maintain such insurance), primary mortgage insurance applicable
to each Mortgage Loan in accordance with the provisions of this Agreement. The
Master Servicer shall not, and shall not permit the Servicer to, cancel or
refuse to renew any primary mortgage insurance policy that is in effect at the
date of the initial issuance of the Mortgage Note and is required to be kept in
force hereunder except in accordance with the provisions of this Agreement.

possession and custody of the originals (to the extent available) of any primary
mortgage insurance policies, or certificate of insurance if applicable, and any
certificates of renewal as to the foregoing as may be issued from time to time
as contemplated by this Agreement. Until all amounts distributable in respect of
the Certificates has been distributed in full and the Master Servicer and the
Servicer have otherwise fulfilled their respective obligations under this
Agreement, the Trustee or the Custodian shall also retain possession and custody
of each Mortgage File in accordance with and subject to the terms and conditions
of this Agreement and the Custodial Agreement. The Master Servicer shall
promptly deliver or cause to be delivered to the Trustee or the Custodian, upon
the execution or receipt thereof the originals of any primary mortgage insurance
policies, any certificates of renewal, and such other documents or instruments

Certificateholders. The Master Servicer shall cause the Servicer to sell, any
REO Property as expeditiously as possible and in accordance with the provisions
of this Agreement. Further, the Master Servicer shall cause the Servicer to sell
any REO Property prior to three years after the end of the calendar year of its

Fund of such REO Property subsequent to such three-year period will not result
in the imposition of taxes on "prohibited transactions" of any REMIC hereunder
as defined in section 860F of the Code or cause any REMIC hereunder to fail to
qualify as a REMIC at any time that any Certificates are outstanding, in which
case the Trust Fund may continue to hold such Mortgaged Property (subject to any
conditions contained in such Opinion of Counsel) or (ii) the Servicer shall have
applied for, prior to the expiration of such three-year period, an extension of

conserve, such REO Property in the manner and to the extent required by this
Agreement, in accordance with the REMIC Provisions and in a manner that does not
result in a tax on "net income from foreclosure property" or cause such REO
Property to fail to qualify as "foreclosure property" within the meaning of
Section 860G(a)(8) of the Code.

                  (b) The Master Servicer shall cause the Servicer to deposit
all funds collected and received in connection with the operation of any REO
Property in the Collection Account.

                  SECTION 4.19. Obligation of the Master Servicer in Respect of
                                Prepayment Interest Shortfalls.

                  In the event of a Prepayment Interest Shortfall, the Master
Servicer shall remit to the Trustee not later than the Distribution Date an
amount equal to the lesser of (i) the aggregate amounts required to be paid by
the Servicer with respect to Prepayment Interest Shortfalls attributable to
Principal Prepayments on the related Mortgage Loans for the related Distribution
Date, and not so paid by the Servicer and (ii) the Master Servicing Fee for such

                  SECTION 4.20. Collection Account.

                  The Master Servicer shall enforce the obligation of the
Servicer to establish and maintain a Collection Account in accordance with this

Insurance Proceeds, Liquidation Proceeds, and advances made from the Servicer's
own funds (less servicing compensation as permitted by Section 3.15) and all
other amounts to be deposited in the Collection Account.

                  SECTION 4.21. Prepayment Penalty Verification.

                  On or prior to each Servicer Remittance Date, the Servicer
shall provide in an electronic format acceptable to the Master Servicer the data
necessary for the Master Servicer to perform its verification duties set forth
in this Section 4.21. The Master Servicer or a third party reasonably acceptable
to the Master Servicer and the Depositor (the "Verification Agent") will perform
such verification duties and will use its best efforts to issue its findings in
a report (the "Verification Report") delivered to the Master Servicer and the
Depositor within ten (10) Business Days following the related Distribution Date;
provided, however, that if the Verification Agent is unable to issue the
Verification Report within ten (10) Business Days following the Distribution
Date, the Verification Agent may issue and deliver to the Master Servicer and
the Depositor the Verification Report upon the completion of its verification
duties. The Master Servicer shall forward the Verification Report to the
Servicer and shall notify the Servicer if the Master Servicer has determined
that such Servicer did not deliver the appropriate Prepayment Charge to the
Trustee or the appropriate Servicer Prepayment Charge Payment Amount in
accordance with this Agreement. Such written notification from the Master
Servicer shall include the loan number, prepayment penalty code and prepayment
penalty amount as calculated by the Master Servicer or the Verification Agent,
as applicable, of each Mortgage Loan for which there is a discrepancy. If the
Servicer agrees with the verified amounts, the Servicer shall adjust the
immediately succeeding Servicer Report and the amount remitted to the Trustee
with respect to prepayments accordingly. If the Servicer disagrees with the
determination of the Master Servicer, the Servicer shall, within five (5)
Business Days of its receipt of the Verification Report, notify the Master
Servicer of such disagreement and provide the Master Servicer with detailed
information to support such Servicer's position. The Servicer and the Master
Servicer shall cooperate to resolve any discrepancy on or prior to the
immediately succeeding Servicer Remittance Date, and the Servicer will indicate
the effect of such resolution on the related Servicer Report and shall adjust
the amount remitted with respect to prepayments on such Servicer Remittance Date
accordingly.

                  During such time as the Servicer and the Master Servicer are
resolving discrepancies with respect to the Prepayment Charges, no payments in
respect of any disputed Prepayment Charges will be remitted to the Trustee for
deposit in the Distribution Account and the Master Servicer shall not be
obligated to remit such payments, unless otherwise required pursuant to Section
8.01 hereof. In connection with such duties, the Master Servicer shall be able
to rely solely on the information provided to it by the Servicer in accordance
with this Section. The Master Servicer shall not be responsible for verifying
the accuracy of any of the information provided to it by the Servicer.

                  In the event of a Principal Prepayment in full with respect to
any Mortgage Loan, the Servicer shall deliver to the Master Servicer a
certification of a Servicing Officer substantially in the form of Exhibit D no
later than the third Business Day following the immediately succeeding
Determination Date with a copy to the Class CE Certificateholder.

                  (d) All distributions made with respect to each Class of
Certificates on each Distribution Date shall be allocated PRO RATA among the
outstanding Certificates in such Class based on their respective Percentage
Interests. Payments in respect of each Class of Certificates on each
Distribution Date will be made to the Holders of the respective Class of record
on the related Record Date (except as otherwise provided in Section 5.01(e) or
Section 10.01 respecting the final distribution on such Class), based on the
aggregate Percentage Interest represented by their respective Certificates, and
shall be made by wire transfer of immediately available funds to the account of
any such Holder at a bank or other entity having appropriate facilities
therefor, if such Holder shall have so notified the Trustee in writing at least
five Business Days prior to the Record Date immediately prior to such
Distribution Date and is the registered owner of Certificates having an initial
aggregate Certificate Principal Balance that is in excess of the lesser of (i)
$5,000,000 or (ii) two-thirds of the initial Certificate Principal Balance of
such Class of Certificates, or otherwise by check mailed by first class mail to
the address of such Holder appearing in the Certificate Register. The final
distribution on each Certificate will be made in like manner, but only upon
presentment and surrender of such Certificate at the Corporate Trust Office of
the Trustee or such other location specified in the notice to Certifcateholders
of such final distribution.

                  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 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 Certificate Owners that it represents. None of the Trustee, the
Depositor, the Servicer, the Securities Administrator or the Master Servicer
shall have any responsibility therefor except as otherwise provided by this
Agreement or applicable law.

                  (e) The rights of the Certificateholders to receive
         distributions in respect of the Certificates, and all interests of the
         Certificateholders in such distributions, shall be as set forth in this
         Agreement. None of the Holders of any Class of Certificates, the
         Trustee, the Servicer, the Securities Administrator or the Master
         Servicer 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 10.01, whenever
         the Trustee expects that the final distribution with respect to any
         Class of Certificates will be made on the next Distribution Date, the
         Trustee shall, no later than three (3) days before the related
         Distribution Date, mail to each Holder 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 Trustee therein specified, and

                  (ii) no interest shall accrue on such Certificates from and
         after the end of the related Interest Accrual Period.

                  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 in trust by the Trustee and credited to the account of the
appropriate non-tendering Holder or Holders. If any Certificates as to which
notice has been given pursuant to this Section 5.01(e) 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 shall, directly or through an agent, mail a final
notice to the remaining non-tendering Certificateholders concerning surrender of
their Certificates but shall continue to hold any remaining funds for the
benefit of non-tendering Certificateholders. The costs and expenses of
maintaining the funds in trust and of contacting such Certificateholders shall
be paid out of the assets remaining in such trust fund. If within one year after
the final notice any such Certificates shall not have been surrendered for
cancellation, the Trustee shall pay to the Depositor all such amounts, and all
rights of non-tendering Certificateholders in or to such amounts shall thereupon
cease. No interest shall accrue or be payable to any Certificateholder on any
amount held in trust by the Trustee as a result of such Certificateholder's
failure to surrender its Certificate(s) on the final Distribution Date for final
payment thereof in accordance with this Section 5.01(e). Any such amounts held
in trust by the Trustee shall be held uninvested in an Eligible Account.

                  (g) Notwithstanding anything to the contrary herein, (i) in no
event shall the Certificate Principal Balance of a Class A Certificate or a
Mezzanine Certificate be reduced more than once in respect of any particular
amount both (a) allocated to such Certificate in respect of Realized Losses
pursuant to Section 5.04 and (b) distributed to the Holder of such Certificate
in reduction of the Certificate Principal Balance thereof pursuant to this
Section 5.01 from Net Monthly Excess Cashflow and (ii) in no event shall the
Uncertificated Balance of a REMIC Regular Interest be reduced more than once in
respect of any particular amount both (a) allocated to such REMIC Regular
Interest in respect of Realized Losses pursuant to Section 5.04 and (b)
distributed on such REMIC Regular Interest in reduction of the Uncertificated
Balance thereof pursuant to this Section 5.01.

                  SECTION 5.02. Statements to Certificateholders.

                  On each Distribution Date, the Securities Administrator (based
on the information set forth in the Servicer Report for such Distribution Date)
shall make available to each Holder of the Certificates, a statement as to the
distributions made on such Distribution Date setting forth:

                  SECTION 5.03. Servicer Reports; P&I Advances.

                  (a) On the Business Day following each Determination Date, the
Servicer shall deliver to the Master Servicer and the Securities Administrator
by telecopy (or by such other means as the Servicer, the Master Servicer and the
Securities Administrator may agree from time to time) a Servicer Report with
respect to the related Distribution Date, in a form mutually acceptable to the
Servicer, the Master Servicer and the Securities Administrator. On the same
date, the Servicer shall electronically transmit to the Master Servicer and the
Securities Administrator, a data file containing the information set forth in
such Servicer Report with respect to the related Distribution Date. Such
Servicer Report shall include (i) the amount of P&I Advances to be made by the
Servicer in respect of the related Distribution Date, the aggregate amount of
P&I Advances outstanding after giving effect to such P&I Advances, and the
aggregate amount of Nonrecoverable P&I Advances in respect of such Distribution
Date and (ii) such other information with respect to the Mortgage Loans as the
Securities Administrator may reasonably require to perform the calculations
necessary to make the distributions contemplated by Section 5.01 and to prepare
the statements to Certificateholders contemplated by Section 5.02. The
Securities Administrator shall not be responsible to recompute, recalculate or
verify any information provided to it by the Servicer.

                  (b) The amount of P&I Advances to be made by the Servicer on
any Distribution Date shall equal, subject to Section 5.03(d), (i) the aggregate
amount of Monthly Payments (net of the related Servicing Fee), due during the
related Due Period in respect of the Mortgage Loans, which Monthly Payments were
delinquent as of the close of business on the related Determination Date and
(ii) with respect to each REO Property, which REO Property was acquired during
or prior to the related Prepayment Period and as to which such REO Property an
REO Disposition did not occur during the related Prepayment Period, an amount
equal to the excess, if any, of only the interest portion of the Monthly
Payments (net of the related Servicing Fee) that would have been due on the
related Due Date in respect of the related Mortgage Loans, over the net income
from such REO Property deposited in the Collection Account pursuant to Section
3.21 for distribution on such Distribution Date. For purposes of the preceding
sentence, the Monthly Payment on each Balloon Mortgage Loan with a delinquent
Balloon Payment is equal to the assumed monthly payment that would have been due
on the related Due Date based on the original principal amortization schedule
for such Balloon Mortgage Loan.

                  By 3:00 p.m. New York time on the Servicer Remittance Date,
the Servicer shall remit in immediately available funds to the Trustee for
deposit in the Distribution Account an amount equal to the aggregate amount of
P&I Advances, if any, to be made in respect of the Mortgage Loans for the
related Distribution Date either (i) from its own funds or (ii) from the
Collection Account, to the extent of any Amounts Held For Future Distribution on
deposit therein (in which case it will cause to be made an appropriate entry in
the records of the Collection Account that Amounts Held For Future Distribution
have been, as permitted by this Section 4.03, used by the Servicer in discharge
of any such P&I Advance) or (iii) in the form of any combination of (i) and (ii)

                                     -119-
<PAGE>

aggregating the total amount of P&I Advances to be made by the Servicer with
respect to the Mortgage Loans. In addition, the Servicer shall have the right to
reimburse itself for any outstanding P&I Advance made by it from its own funds
from Amounts Held for Future Distribution. Any Amounts Held For Future
Distribution used by the Servicer to make P&I Advances or to reimburse itself
for outstanding P&I Advances shall be appropriately reflected in the Servicer's
records and replaced by the Servicer by deposit in the Collection Account no
later than the close of business on the Servicer Remittance Date immediately
following the Due Period or Prepayment Period for which such amounts relate. The
Trustee will notify the Servicer and the Master Servicer by the close of
business on the Business Day prior to the Distribution Date in the event that
the amount remitted by the Servicer to the Trustee on such date is less than the
P&I Advances required to be made by the Servicer for the related Distribution
Date.

                  (c) The obligation of the Servicer to make such P&I Advances
is mandatory, notwithstanding any other provision of this Agreement but subject
to (d) below, and, with respect to any Mortgage Loan or REO Property, shall
continue until a Final Recovery Determination in connection therewith or the
removal thereof from the Trust Fund pursuant to any applicable provision of this
Agreement, except as otherwise provided in this Section.

                  (d) Notwithstanding anything herein to the contrary, no P&I
Advance or Servicing Advance shall be required to be made hereunder by the
Servicer if such P&I Advance or Servicing Advance would, if made, constitute a
Nonrecoverable P&I Advance or Nonrecoverable Servicing Advance, respectively.
The determination by the Servicer that it has made a Nonrecoverable P&I Advance
or a Nonrecoverable Servicing Advance or that any proposed P&I Advance or
Servicing Advance, if made, would constitute a Nonrecoverable P&I Advance or
Nonrecoverable Servicing Advance, respectively, shall be evidenced by a
certification of a Servicing Officer delivered to the Depositor, the Master
Servicer and the Trustee.

                  (e) Subject to and in accordance with the provisions of
Article VIII, in the event the Servicer fails to make any such P&I Advance, then
the Trustee (in its capacity as successor servicer) or any other successor
Servicer (including the Master Servicer) shall be required to make such P&I
Advance on the Distribution Date on which the Servicer was required to make such
Advance, subject to its determination of recoverability.

                  (f) Two Business Days prior to each Distribution Date, the
Securities Administrator shall deliver to the Trustee by telecopy (or by such
other means as the Securities Administrator and the Trustee may agree from time
to time) a Remittance Report with respect to the related Distribution Date in
form and substance acceptable to the Trustee which shall contain the
instructions of the Securities Administrator with respect to all distributions,
allocations, deposits, withdrawals and other actions to be taken by the Trustee
on such Distribution Date as set forth in this Article V. The Trustee shall not
be obligated to recompute, recalculate or verify any information provided to it
by the Securities Administrator.

                  SECTION 5.04. Allocation of Realized Losses.

                  (a) Prior to the Determination Date, the Servicer shall
determine as to each Mortgage Loan and REO Property: (i) the total amount of
Realized Losses, if any, incurred in

                                     -120-
<PAGE>

connection with any Final Recovery Determinations made during the related
Prepayment Period; and (ii) the respective portions of such Realized Losses
allocable to interest and allocable to principal. Prior to each Determination
Date, the Servicer shall also determine as to each Mortgage Loan: (i) the total
amount of Realized Losses, if any, incurred in connection with any Deficient
Valuations made during the related Prepayment Period; and (ii) the total amount
of Realized Losses, if any, incurred in connection with Debt Service Reductions
in respect of Monthly Payments due during the related Due Period. The
information described in the two preceding sentences that is to be supplied by
the Servicer shall be evidenced by an Officers' Certificate delivered to the
Trustee by the Servicer prior to the Determination Date immediately following
the end of the Prepayment Period during which any such Realized Loss was
incurred.

                  (b) All Realized Losses on the Mortgage Loans allocated to any
REMIC I Regular Interest pursuant to Section 4.04(c) on the Mortgage Loans shall
be allocated by the Trustee, based solely on the instructions of the Securities
Administrator on each Distribution Date as follows: first, to Net Monthly Excess
Cashflow; second, to the Class CE Certificates, until the Certificate Principal
Balance thereof has been reduced to zero; third, to the Class M-6 Certificates,
until the Certificate Principal Balance thereof has been reduced to zero;
fourth, to the Class M-5 Certificates, until the Certificate Principal Balance
thereof has been reduced to zero; fifth, to the Class M-4 Certificates, until
the Certificate Principal Balance thereof has been reduced to zero sixth, to the
Class M-3 Certificates, until the Certificate Principal Balance thereof has been
reduced to zero; seventh, to the Class M-2 Certificates, until the Certificate
Principal Balance thereof has been reduced to zero; and eighth, to the Class M-1
Certificates, until the Certificate Principal Balance thereof has been reduced
to zero. All Realized Losses to be allocated to the Certificate Principal
Balances of all Classes on any Distribution Date shall be so allocated after the
actual distributions to be made on such date as provided above. All references
above to the Certificate Principal Balance of any Class of Certificates shall be
to the Certificate Principal Balance of such Class immediately prior to the
relevant Distribution Date, before reduction thereof by any Realized Losses, in
each case to be allocated to such Class of Certificates, on such Distribution
Date.

                  Any allocation of Realized Losses to a Mezzanine Certificate
on any Distribution Date shall be made by reducing the Certificate Principal
Balance thereof by the amount so allocated; any allocation of Realized Losses to
a Class CE Certificates shall be made by reducing the amount otherwise payable
in respect thereof pursuant to Section 5.01(a)(7)(xvii). No allocations of any
Realized Losses shall be made to the Certificate Principal Balances of the Class
A Certificates or the Class P Certificates.

                  As used herein, an allocation of a Realized Loss on a "pro
rata basis" among two or more specified Classes of Certificates means an
allocation on a pro rata basis, among the various Classes so specified, to each
such Class of Certificates on the basis of their then outstanding Certificate
Principal Balances prior to giving effect to distributions to be made on such
Distribution Date. All Realized Losses and all other losses allocated to a Class
of Certificates hereunder will be allocated among the, Certificates of such
Class in proportion to the Percentage Interests evidenced thereby.

                  (c) All Realized Losses on the Mortgage Loans shall be
allocated by the Trustee, based solely on the instructions of the Securities
Administrator on each Distribution Date to REMIC

                                     -121-

I Regular Interest I-LT1 and REMIC I Regular Interest I-LT2 until the
Uncertificated Balances thereof have been reduced to zero.

                  (d)(i) The REMIC II Marker Percentage of all Realized Losses
on the Mortgage Loans shall be allocated by the Trustee, based solely on the
instructions of the Securities Administrator, on each Distribution Date to the
following REMIC II Regular Interests in the specified percentages, as follows:
first, to Uncertificated Interest payable to the REMIC II Regular Interest
II-LTAA and REMIC II Regular Interest II-LTZZ up to an aggregate amount equal to
the REMIC II Interest Loss Allocation Amount, 98% and 2%, respectively; second,
to the Uncertificated Balances of the REMIC II Regular Interest II-LTAA and
REMIC II Regular Interest II-LTZZ up to an aggregate amount equal to the REMIC
II Principal Loss Allocation Amount, 98% and 2%, respectively; third, to the
Uncertificated Balances of REMIC II Regular Interest II-LTAA, REMIC II Regular
Interest II-LTM6 and REMIC II Regular Interest II-LTZZ, 98%, 1.00% and 1%,
respectively, until the Uncertificated Balances of REMIC II Regular Interest
II-LTM6 has been reduced to zero; fourth to the Uncertificated Balances of REMIC
II Regular Interest II-LTAA, REMIC II Regular Interest II-LTM5 and REMIC II
Regular Interest II-LTZZ, 98%, 1.00%, and 1%, respectively, until the
Uncertificated Balance of REMIC II Regular Interest II-LTM5 has been reduced to
zero; fifth to the Uncertificated Balances of REMIC II Regular Interest II-LTAA,
REMIC II Regular Interest II-LTM4 and REMIC II Regular Interest II-LTZZ, 98%, 1%
and 1%, respectively, until the Uncertificated Balance of REMIC II Regular
Interest II-LTM4 has been reduced to zero; sixth to the Uncertificated Balances
of REMIC II Regular Interest II-LTAA, REMIC II Regular Interest II-LTM3 and
REMIC II Regular Interest II-LTZZ, 98%, 1% and 1%, respectively, until the
Uncertificated Balance of REMIC II Regular Interest II-LTM3 has been reduced to
zero; seventh to the Uncertificated Balances of REMIC II Regular Interest
II-LTAA, REMIC II Regular Interest II-LTM2 and REMIC II Regular Interest
II-LTZZ, 98%, 1% and 1%, respectively, until the Uncertificated Balance of REMIC
II Regular Interest II-LTM2 has been reduced to zero; and eighth, to the
Uncertificated Balances of REMIC II Regular Interest II-LTAA, REMIC II Regular
Interest II-LTM1 and REMIC II Regular Interest II-LTZZ, 98%, 1% and 1%,
respectively, until the Uncertificated Balance of REMIC II Regular Interest
II-LTM1 has been reduced to zero.

                  (ii) The REMIC II Sub WAC Allocation Percentage of all
Realized Losses shall be applied after all distributions have been made on each
Distribution Date first, so as to keep the Uncertificated Balance of each REMIC
II Regular Interest ending with the designation "GRP" equal to 0.01% of the
aggregate Stated Principal Balance of the Mortgage Loans in the related Loan
Group; second, to each REMIC II Regular Interest ending with the designation
"SUB," so that the Uncertificated Balance of each such REMIC II Regular Interest
is equal to 0.01% of the excess of (x) the aggregate Stated Principal Balance of
the Mortgage Loans in the related Loan Group over (y) the current Certificate
Principal Balance of the Class A Certificate in the related Loan Group (except
that if any such excess is a larger number than in the preceding distribution
period, the least amount of Realized Losses shall be applied to such REMIC II
Regular Interests such that the REMIC II Subordinated Balance Ratio is
maintained); and third, any remaining Realized Losses shall be allocated to
REMIC II Regular Interest II-LTXX.

Trustee reasonably believes are applicable under the Code. The consent of
Certificateholders shall not be required for such withholding. In the event the
Trustee does withhold any amount from interest or original issue discount
payments or advances thereof to any Certificateholder pursuant to federal
withholding requirements, the Trustee shall indicate the amount withheld to such
Certificateholders.

                  (a) The Certificates in the aggregate will represent the
entire beneficial ownership interest in the Mortgage Loans and all other assets
included in REMIC I.

                  The Certificates will be substantially in the forms annexed
hereto as Exhibits A-1 through A-6. The Certificates of each Class will be
issuable in registered form only, in denominations of authorized Percentage
Interests as described in the definition thereof. Each Certificate will share
ratably in all rights of the related Class.

                  Upon original issue, the Certificates shall be executed,
authenticated and delivered by the Trustee to and upon the order of the
Depositor. The Certificates shall be executed by manual or facsimile signature
on behalf of the Trust by the Trustee by an authorized signatory. Certificates
bearing the manual or facsimile signatures of individuals who were at any time
the proper officers of the Trustee shall bind the Trust, 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, unless there appears on such
Certificate a certificate of authentication substantially in the form provided
herein executed by the Trustee by manual signature, and such certificate of
authentication 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.

                  (b) The Class A Certificates, the Class A-IO Certificates and
the Mezzanine Certificates shall initially be issued as one or more Certificates
held by the Book-Entry Custodian or, if appointed to hold such Certificates as
provided below, the Depository and registered in the name of the Depository or
its nominee and, except as provided below, registration of such Certificates may
not be transferred by the Trustee except to another Depository that agrees to
hold such Certificates for the respective Certificate Owners with Ownership
Interests therein. The Certificate Owners shall hold their respective Ownership
Interests in and to such Certificates through the book-entry facilities of the
Depository and, except as provided 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 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. The Trustee is hereby
initially appointed as the Book-Entry Custodian and hereby agrees to act as such
in accordance herewith and in accordance with the agreement that it has with the
Depository authorizing it to act as such. The Book-Entry Custodian may, and, if
it is no longer qualified to act as such, the Book-Entry Custodian shall,
appoint, by a written instrument delivered to the Depositor, the Servicer and,
if the Trustee is not the Book-Entry

                                     -124-

Custodian, the Trustee, any other transfer agent (including the Depository or
any successor Depository) to act as Book-Entry Custodian under such conditions
as the predecessor Book-Entry Custodian and the Depository or any successor
Depository may prescribe, provided that the predecessor Book-Entry Custodian
shall not be relieved of any of its duties or responsibilities by reason of any
such appointment of other than the Depository. If the Trustee resigns or is
removed in accordance with the terms hereof, the successor Trustee or, if it so
elects, the Depository shall immediately succeed to its predecessor's duties as
Book-Entry Custodian. The Depositor shall have the right to inspect, and to
obtain copies of, any Certificates held as Book-Entry Certificates by the
Book-Entry Custodian.

                  The Trustee, the Servicer, the Securities Administrator, the
Master Servicer and the Depositor 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 the
Book-Entry 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.

                  If (i)(A) the Depositor advises the Trustee in writing that
the Depository is no longer willing or able to properly discharge its
responsibilities as Depository, and (B) the Depositor is unable to locate a
qualified successor, (ii) the Depositor at its option advises the Trustee in
writing that it elects to terminate the book-entry system through the Depository
or (iii) after the occurrence of a Servicer Event of Default, Certificate Owners
representing in the aggregate not less than 51% of the Ownership Interests of
the Book-Entry Certificates advise the Trustee through the Depository, in
writing, that the continuation of a book-entry system through the Depository is
no longer in the best interests of the Certificate Owners, the Trustee shall
notify all Certificate Owners, through the Depository, of the occurrence of any
such event and of the availability of Definitive Certificates to Certificate
Owners requesting the same. Upon surrender to the Trustee of the Book-Entry
Certificates by the Book-Entry Custodian or the Depository, as applicable,
accompanied by registration instructions from the Depository for registration of
transfer, the Trustee shall cause the Definitive Certificates to be issued. Such
Definitive Certificates will be issued in minimum denominations of $10,000
except that any beneficial ownership that was represented by a Book-Entry
Certificate in an amount less than $10,000 immediately prior to the issuance of
a Definitive Certificate shall be issued in a minimum denomination equal to the
amount represented by such Book-Entry Certificate. None of the Depositor, the
Servicer, the Master Servicer or the Trustee shall be liable for any delay in
the delivery of such instructions and may conclusively rely on, and shall be
protected in relying on, such instructions. Upon the issuance of Definitive
Certificates all references herein to obligations imposed upon or to be
performed by the Depository shall be deemed to be imposed upon and performed by
the Trustee, to the extent applicable with respect to such Definitive
Certificates, and the Trustee shall recognize the Holders of the Definitive
Certificates as Certificateholders hereunder.

                  SECTION 6.02. Registration of Transfer and Exchange of
                                Certificates.

                  (a) The Trustee shall cause to be kept at one of the offices
or agencies to be appointed by the Trustee in accordance with the provisions of
Section 9.11, a Certificate Register for the Certificates in which, subject to
such reasonable regulations as it may prescribe, the Trustee shall provide for
the registration of Certificates and of transfers and exchanges of Certificates
as herein provided.

                  (b) No transfer of any Class CE Certificate, Class P
Certificate or Residual Certificate shall be made unless that transfer is made
pursuant to an effective registration statement under the Securities Act of
1933, as amended (the "1933 Act"), and effective registration or qualification
under applicable state securities laws, or is made in a transaction that does
not require such registration or qualification. In the event that such a
transfer of a Class CE Certificate, Class P Certificate or Residual Certificate
is to be made without registration or qualification (other than in connection
with the initial transfer of any such Certificate by the Depositor), the Trustee
shall require receipt of: (i) if such transfer is purportedly being made in
reliance upon Rule 144A under the 1933 Act, written certifications from the
Certificateholder desiring to effect the transfer and from such
Certificateholder's prospective transferee, substantially in the form attached
hereto as Exhibit B-1; (ii) if such transfer is purportedly being made in
reliance upon Rule 501(a) under the 1933 Act, written certifications from the
Certificateholder desiring to effect the transfer and from such
Certificateholder's prospective transferee, substantially in the form attached
hereto as Exhibit B-2 and (iii) in all other cases, an Opinion of Counsel
satisfactory to the Trustee that such transfer may be made without such
registration or qualification (which Opinion of Counsel shall not be an expense
of the Trust Fund or of the Depositor, the Trustee, the Master Servicer, the
Securities Administrator or the Servicer), together with copies of the written
certification(s) of the Certificateholder desiring to effect the transfer and/or
such Certificateholder's prospective transferee upon which such Opinion of
Counsel is based, if any. Neither of the Depositor nor the Trustee is obligated
to register or qualify any such Certificates under the 1933 Act or any other
securities laws or to take any action not otherwise required under this
Agreement to permit the transfer of such Certificates without registration or
qualification. Any Certificateholder desiring to effect the transfer of any such
Certificate shall, and does hereby agree to, indemnify the Trustee, the
Depositor, the Master Servicer, the Securities Administrator and the Servicer
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.

                  (c) No transfer of a Class CE Certificate, Class P Certificate
or a Residual Certificate or any interest therein shall be made to any Plan
subject to ERISA or Section 4975 of the Code, any Person acting, directly or
indirectly, on behalf of any such Plan or any Person acquiring such Certificates
with "Plan Assets" of a Plan within the meaning of the Department of Labor
regulation promulgated at 29 C.F.R. ss. 2510.3-101 ("Plan Assets") unless the
Depositor, the Trustee, and the Servicer are provided with an Opinion of Counsel
which establishes to the satisfaction of the Depositor, the Trustee, the Master
Servicer, the Securities Administrator and the Servicer that the purchase of
such Certificates is permissible under applicable law, will not constitute or
result in any prohibited transaction under ERISA or Section 4975 of the Code and
will not subject the Depositor, the Servicer, the Trustee, the Master Servicer,
the Securities Administrator or the Trust Fund to any obligation or liability
(including obligations or liabilities under ERISA or Section 4975 of the Code)

                                     -126-
<PAGE>

in addition to those undertaken in this Agreement, which Opinion of Counsel
shall not be an expense of the Depositor, the Servicer, the Trustee, the Master
Servicer, the Securities Administrator or the Trust Fund. An Opinion of Counsel
will not be required in connection with the initial transfer of any such
Certificate by the Depositor to an affiliate of the Depositor (in which case,
the Depositor or any affiliate thereof shall have deemed to have represented
that such affiliate is not a Plan or a Person investing Plan Assets) and the
Trustee shall be entitled to conclusively rely upon a representation (which,
upon the request of the Trustee, shall be a written representation) from the
Depositor of the status of such transferee as an affiliate of the Depositor.

                  Each Transferee of a Mezzanine Certificate will be deemed to
have represented by virtue of its purchase or holding of such Certificate (or
interest therein) that either (a) such Transferee is not a Plan or purchasing
such Certificate with Plan Assets, (b) it has acquired and is holding such
Certificate in reliance on Prohibited Transaction Exemption ("PTE") 94-84 or FAN
97-03E, as amended by PTE 97-34, 62 Fed. Reg. 39021 (July 21, 1997), PTE
2000-58, 65 Fed. Reg. 67765 (November 13, 2000) and PTE 2002-41, 67 Fed. Reg.
54487 (August 22, 2002) (the "Exemption"), and that it understands that there
are certain conditions to the availability of the Exemption including that such
Certificate must be rated, at the time of purchase, not lower than "BBB-" (or
its equivalent) by a Rating Agency or (c) the following conditions are
satisfied: (i) such Transferee is an insurance company, (ii) the source of funds
used to purchase or hold such Certificate (or interest therein) is an "insurance
company general account" (as defined in U.S. Department of Labor Prohibited
Transaction Class Exemption ("PTCE") 95-60, and (iii) the conditions set forth
in Sections I and III of PTCE 95-60 have been satisfied. If any Mezzanine
Certificate or any interest therein is acquired or held in violation of the
conditions described in this paragraph, the next preceding permitted beneficial
owner will be treated as the beneficial owner of that Mezzanine Certificate,
retroactive to the date of transfer to the purported beneficial owner. Any
purported beneficial owner whose acquisition or holding of any such certificate
or interest therein was effected in violation of the conditions described in
this paragraph shall indemnify and hold harmless the Depositor, the Trustee, the
Servicer, the Master Servicer, the Securities Administrator and the Trust Fund
from and against any and all liabilities, claims, costs or expenses incurred by
those parties as a result of that acquisition or holding.

                  (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 or its
designee under clause (iii)(A) below to deliver payments to a Person other than
such Person and to negotiate the terms of any mandatory sale under clause
(iii)(B) below 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:

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

                                    (B) In connection with any proposed Transfer
                           of any Ownership Interest in a Residual Certificate,
                           the Trustee shall require delivery to it, and shall
                           not register the Transfer of any Residual Certificate
                           until its receipt of, an affidavit and agreement (a
                           "Transfer Affidavit and Agreement," in the form
                           attached hereto as Exhibit B-3) from the proposed
                           Transferee, in form and substance satisfactory to the
                           Trustee, 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, and
                           that it has reviewed the provisions of this Section
                           6.02(d) and agrees to be bound by them.

                                    (C) Notwithstanding the delivery of a
                           Transfer Affidavit and Agreement by a proposed
                           Transferee under clause (B) above, if a Responsible
                           Officer of the Trustee who is assigned to this
                           transaction 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.

                                    (D) Each Person holding or acquiring any
                           Ownership Interest in a Residual 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 in a
                           Residual Certificate and (Y) not to transfer its
                           Ownership Interest unless it provides a Transferor
                           Affidavit (in the form attached hereto as Exhibit
                           B-2) to the Trustee stating that, among other things,
                           it has no actual knowledge that such other Person is
                           not a Permitted Transferee.

                                    (E) Each Person holding or acquiring an
                           Ownership Interest in a Residual Certificate, by
                           purchasing an Ownership Interest in such Certificate,
                           agrees to give 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 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) The Trustee will register the Transfer of any
                  Residual Certificate only if it shall have received the
                  Transfer Affidavit and Agreement and all of such other
                  documents as shall have been reasonably required by the
                  Trustee as a condition to such registration. In addition, no
                  Transfer of a Residual Certificate shall be made unless the
                  Trustee shall have received a representation letter from the
                  Transferee of such Certificate to the effect that such
                  Transferee is a Permitted Transferee.

                           (iii) (A) If any purported Transferee shall become a
                  Holder of a Residual Certificate in violation of the
                  provisions of this Section 6.02(d), then the last preceding
                  Permitted Transferee 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. The Trustee shall be under no liability to any
                  Person for any registration of Transfer of a Residual
                  Certificate that is in fact not permitted by this Section
                  6.02(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 6.02(d) and to the
                           extent that the retroactive restoration of the rights
                           of the holder of such Residual Certificate as
                           described in clause (iii)(A) above shall be invalid,
                           illegal or unenforceable, then the Trustee shall have
                           the right, without notice to the holder or any prior
                           holder of such Residual Certificate, to sell such
                           Residual Certificate to a purchaser selected by the
                           Trustee on such terms as the Trustee may choose. Such
                           purported Trustee shall promptly endorse and deliver
                           each Residual Certificate in accordance with the
                           instructions of the Trustee. Such purchaser may be
                           the Trustee itself or any Affiliate of the Trustee.
                           The proceeds of such sale, net of the commissions
                           (which may include commissions payable to the Trustee
                           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 (iii)(B) shall be determined in the
                           sole discretion of the Trustee, and the Trustee shall
                           not be liable to any Person having an Ownership
                           Interest in a Residual Certificate as a result of its
                           exercise of such discretion.

                           (iv) The Trustee shall make available to the Internal
                  Revenue Service and those Persons specified by the REMIC
                  Provisions all information necessary to compute any tax
                  imposed (A) as a result of the Transfer of an Ownership
                  Interest in a Residual Certificate to any Person who is a
                  Disqualified Organization, 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 (B) as a result of any regulated
                  investment company, real estate investment trust, common trust
                  fund, partnership, trust, estate or organization described in
                  Section 1381 of the Code that holds an Ownership Interest in a
                  Residual Certificate having as among its record holders at any
                  time any Person which is a Disqualified Organization.
                  Reasonable compensation for providing such information may be
                  charged or collected by the Trustee.

                           (v) The provisions of this Section 6.02(d) set forth
                  prior to this subsection (v) may be modified, added to or
                  eliminated, provided that there shall have been delivered to
                  the Trustee at the expense of the party seeking to modify, add
                  to or eliminate any such provision the following:

                                     -129-
<PAGE>

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

                                    (B) an Opinion of Counsel, in form and
                           substance satisfactory to the Trustee, to the effect
                           that such modification of, addition to or elimination
                           of such provisions will not cause any Trust REMIC to
                           cease to qualify as a REMIC and will not cause any
                           Trust REMIC, as the case may be, to be subject to an
                           entity-level tax caused by the Transfer of any
                           Residual Certificate to a Person that is not a
                           Permitted Transferee or a Person other than the
                           prospective transferee to be subject to a REMIC-tax
                           caused by the Transfer of a Residual Certificate to a
                           Person that is not a Permitted Transferee.

                  (e) Subject to the preceding subsections, upon surrender for
registration of transfer of any Certificate at any office or agency of the
Trustee maintained for such purpose pursuant to Section 9.11, the Trustee shall
execute, 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 the Holder thereof, any Certificate may
be exchanged for other Certificates of the same Class with authorized
denominations and a like aggregate Percentage Interest, upon surrender of such
Certificate to be exchanged at any office or agency of the Trustee maintained
for such purpose pursuant to Section 9.11. Whenever any Certificates are so
surrendered for exchange, the Trustee shall execute, authenticate and deliver,
the Certificates which the Certificateholder making the exchange is entitled to
receive. Every Certificate presented or surrendered for transfer or exchange
shall (if so required by the Trustee) be duly endorsed by, or be accompanied by
a written instrument of transfer in the form satisfactory to the Trustee duly
executed by, the Holder thereof or his attorney duly authorized in writing.

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

                  (h) All Certificates surrendered for transfer and exchange
shall be canceled and destroyed by the Trustee in accordance with its customary
procedures.

                  SECTION 6.03. Mutilated, Destroyed, Lost or Stolen
                                Certificates.

                  If (i) any mutilated Certificate is surrendered to the
Trustee, or the Trustee receives evidence to its satisfaction of the
destruction, loss or theft of any Certificate and of the ownership thereof, and
(ii) there is delivered to Trustee such security or indemnity as may be required
by it to save it harmless, then, in the absence of actual knowledge by the
Trustee that such Certificate has been acquired by a bona fide purchaser, the
Trustee, shall execute, authenticate and deliver, in

                                     -130-
<PAGE>

exchange for or in lieu of any such mutilated, destroyed, lost or stolen
Certificate, a new Certificate of the same Class and of like denomination and
Percentage Interest. Upon the issuance of any new Certificate under this
Section, the Trustee 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) 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 6.04. Persons Deemed Owners.

                  The Depositor, the Servicer, the Trustee, the Master Servicer,
the Securities Administrator and any agent of any of them may treat the Person
in whose name any Certificate is registered as the owner of such Certificate for
the purpose of receiving distributions pursuant to Section 4.01 and for all
other purposes whatsoever, and none of the Depositor, the Servicer, the Trustee,
the Master Servicer, the Securities Administrator or any agent of any of them
shall be affected by notice to the contrary.

                  SECTION 6.05. Certain Available Information.

                  On or prior to the date of the first sale of any Class CE
Certificate, Class P Certificate or Residual Certificate to an Independent third
party, the Depositor shall provide to the Securities Administrator ten copies of
any private placement memorandum or other disclosure document used by the
Depositor in connection with the offer and sale of such Certificate. In
addition, if any such private placement memorandum or disclosure document is
revised, amended or supplemented at any time following the delivery thereof to
the Securities Administrator, the Depositor promptly shall inform the Securities
Administrator of such event and shall deliver to the Securities Administrator
ten copies of the private placement memorandum or disclosure document, as
revised, amended or supplemented. The Securities Administrator shall maintain at
its office as set forth in Section 12.05 hereof and shall make available free of
charge during normal business hours for review by any Holder of a Certificate or
any Person identified to the Securities Administrator as a prospective
transferee of a Certificate, originals or copies of the following items: (i) in
the case of a Holder or prospective transferee of a Class CE Certificate, Class
P Certificate or Residual Certificate, the related private placement memorandum
or other disclosure document relating to such Class of Certificates, in the form
most recently provided to the Securities Administrator; and (ii) in all cases,
(A) this Agreement and any amendments hereof entered into pursuant to Section
11.01, (B) all monthly statements required to be delivered to Certificateholders
of the relevant Class pursuant to Section 4.02 since the Closing Date, and all
other notices, reports, statements and written communications delivered to the
Certificateholders of the relevant Class pursuant to this Agreement since the
Closing Date and (C) any copies of all officers' certificates of the Servicer
since the Closing Date delivered to the Master Servicer to evidence such
Person's determination that any P&I Advance or Servicing Advance was, or if
made, would be a Nonrecoverable P&I Advance or Nonrecoverable Servicing Advance.
Copies and mailing of any and all of the foregoing items will be available from
the Securities Administrator upon request at the expense of the Person
requesting the same.

               THE DEPOSITOR, THE SERVICER AND THE MASTER SERVICER

                  SECTION 7.01. Liability of the Depositor, the Servicer and the
                                Master Servicer.

                  The Depositor, the Servicer and the Master Servicer each shall
be liable in accordance herewith only to the extent of the obligations
specifically imposed by this Agreement upon them in their respective capacities
as Depositor, Servicer and Master Servicer and undertaken hereunder by the
Depositor, the Servicer and the Master Servicer herein.

                  SECTION 7.02. Merger or Consolidation of the Depositor, the
                                Servicer or the Master Servicer.

                  Subject to the following paragraph, the Depositor will keep in
full effect its existence, rights and franchises as a corporation under the laws
of the jurisdiction of its incorporation. Subject to the following paragraph,
the Servicer will keep in full effect its existence, rights and franchises as a
limited partnership under the laws of the jurisdiction of its formation. Subject
to the following paragraph, the Master Servicer will keep in full effect its
existence, rights and franchises as a corporation under the laws of the
jurisdiction of its formation. The Depositor, the Servicer and the Master
Servicer 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 Servicer or the Master Servicer may be
merged or consolidated with or into any Person, or transfer all or substantially
all of its assets to any Person, in which case any Person resulting from any
merger or consolidation to which the Depositor, the Servicer or the Master
Servicer shall be a party, or any Person succeeding to the business of the
Depositor, the Servicer or the Master Servicer, shall be the successor of the
Depositor, the Servicer or the Master 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, the Rating Agencies' ratings of the Class A Certificates, the
Class A-IO Certificates and the Mezzanine Certificates in effect immediately
prior to such merger or consolidation will not be qualified, reduced or
withdrawn as a result thereof (as evidenced by a letter to such effect from the
Rating Agencies) and any successor of the Servicer or the Master Servicer shall
meet the eligibility requirements set forth in Section 8.02 or Section 7.06, as
applicable.

                  SECTION 7.03. Limitation on Liability of the Depositor, the
                                Servicer, the Master Servicer and Others.

                  None of the Depositor, the Servicer, the Master Servicer or
any of the directors, officers, employees or agents of the Depositor, the
Servicer or the Master Servicer shall be under any liability to the Trust Fund
or 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 this provision shall not protect the
Depositor, the Servicer, the Master Servicer or any

                                     -132-
<PAGE>

such person against any breach of warranties, representations or covenants made
herein or against any specific liability imposed on any such Person pursuant
hereto or against any liability which would otherwise be imposed by reason of
willful misfeasance, bad faith or gross negligence in the performance of duties
or by reason of reckless disregard of obligations and duties hereunder. The
Depositor, the Servicer, the Master Servicer and any director, officer, employee
or agent of the Depositor, the Servicer and the Master 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 Servicer, the Master Servicer and any director, officer, employee or agent
of the Depositor, the Servicer or the Master Servicer shall be indemnified and
held harmless by the Trust Fund against any loss, liability or expense incurred
in connection with any legal action relating to this Agreement or the
Certificates or any loss, liability or expense incurred other than by reason of
willful misfeasance, bad faith or gross negligence in the performance of duties
hereunder or by reason of reckless disregard of obligations and duties
hereunder. None of the Depositor, the Servicer or the Master Servicer shall be
under any obligation to appear in, prosecute or defend any legal action unless
such action is related to its respective duties under this Agreement and, in its
opinion, does not involve it in any expense or liability; provided, however,
that each of the Depositor, the Servicer and the Master Servicer may in its
discretion undertake any such action which it may deem necessary or desirable
with respect to this Agreement and the rights and duties of the parties hereto
and the interests of the Certificateholders hereunder. In such event, the legal
expenses and costs of such action and any liability resulting therefrom (except
any loss, liability or expense incurred by reason of willful misfeasance, bad
faith or gross negligence in the performance of duties hereunder or by reason of
reckless disregard of obligations and duties hereunder) shall be expenses, costs
and liabilities of the Trust Fund, and the Depositor, the Servicer and the
Master Servicer shall be entitled to be reimbursed therefor from the Collection
Account or the Distribution Account as and to the extent provided in Article III
and Article IV, any such right of reimbursement being prior to the rights of the
Certificateholders to receive any amount in the Collection Account and the
Distribution Account.

                  Notwithstanding anything to the contrary contained herein, the
Servicer shall not be liable for any actions or inactions of any prior servicer
of the Mortgage Loans.

                  SECTION 7.04. Limitation on Resignation of the Servicer.

                  (a) The Servicer shall not resign from the obligations and
duties hereby imposed on it except upon determination that its duties hereunder
are no longer permissible under applicable law or as provided in Section
7.04(c). Any such determination pursuant to the preceding sentence permitting
the resignation of the Servicer shall be evidenced by an Opinion of Counsel to
such effect obtained at the expense of the Servicer and delivered to the Trustee
and the Rating Agencies. No resignation of the Servicer shall become effective
until the Trustee or a successor Servicer shall have assumed the Servicer's
responsibilities, duties, liabilities (other than those liabilities arising
prior to the appointment of such successor) and obligations under this
Agreement.

                  (b) Except as expressly provided herein, the Servicer shall
not assign or transfer any of its rights, benefits or privileges hereunder to
any other Person, or 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 the Servicer hereunder. The foregoing prohibition on assignment
shall not

                                     -133-
<PAGE>

prohibit the Servicer from designating a Sub-Servicer as payee of any
indemnification amount payable to the Servicer hereunder; provided, however,
that as provided in Section 3.02, no Sub- Servicer shall be a third-party
beneficiary hereunder and the parties hereto shall not be required to recognize
any Subservicer as an indemnitee under this Agreement.

                  (c) The Trustee and the Depositor hereby specifically (i)
consent to the pledge and assignment by the Servicer of all of the Servicer's
right, title and interest in, to and under this Agreement to the Servicing
Rights Pledgee, for the benefit of certain lenders and (ii) provided that no
Servicer Event of Default exists, agree that upon delivery to the Trustee by the
Servicing Rights Pledgee of a letter signed by the Servicer whereunder the
Servicer shall resign as Servicer under this Agreement, the Trustee shall
appoint the Servicing Rights Pledgee or its designee as successor Servicer,
provided that at the time of such appointment, the Servicing Rights Pledgee or
such designee meets the requirements of a successor Servicer pursuant to Section
8.02(c)(2) hereof and agrees to be subject to the terms of this Agreement. If,
pursuant to any provision hereof, the duties of the Servicer are transferred to
a successor servicer, the entire amount of the Servicing Fee and other
compensation payable to the Servicer pursuant hereto shall thereafter be payable
to such successor servicer.

                  SECTION 7.05. Limitation on Resignation of the Master
                                Servicer.

                  The Master Servicer shall not resign from the obligations and
duties hereby imposed on it except upon determination that its duties hereunder
are no longer permissible under applicable law. Any such determination pursuant
to the preceding sentence permitting the resignation of the Master Servicer
shall be evidenced by an Opinion of Counsel to such effect obtained at the
expense of the Master Servicer and delivered to the Trustee and the Rating
Agencies. No resignation of the Master Servicer shall become effective until the
Trustee or a successor Master Servicer shall have assumed the Master Servicer's
responsibilities, duties, liabilities (other than those liabilities arising
prior to the appointment of such successor) and obligations under this
Agreement.

                  SECTION 7.06. Assignment of Master Servicing.

                  The Master Servicer may sell and assign its rights and
delegate its duties and obligations in its entirety as Master Servicer under
this Agreement; provided, however, that: (i) the purchaser or transferee accept
in writing such assignment and delegation and assume the obligations of the
Master Servicer hereunder (a) shall be a Person which shall be qualified to
service mortgage loans for Fannie Mae or Freddie Mac; (b) shall have a net worth
of not less than $15,000,000 (unless otherwise approved by each Rating Agency
pursuant to clause (ii) below); (c) shall be reasonably satisfactory to the
Trustee (as evidenced in a writing signed by the Trustee); and (d) shall execute
and deliver to the Trustee an agreement, in form and substance reasonably
satisfactory to the Trustee, which contains an assumption by such Person of the
due and punctual performance and observance of each covenant and condition to be
performed or observed by it as master servicer under this Agreement, any
custodial agreement from and after the effective date of such agreement; (ii)
each Rating Agency shall be given prior written notice of the identity of the
proposed successor to the Master Servicer and each Rating Agency's rating of the
Certificates in effect immediately prior to such assignment, sale and delegation
will not be downgraded, qualified or withdrawn as a result of such assignment,
sale and delegation, as evidenced by a letter to such effect delivered to the
Master

                                     -134-
<PAGE>

Servicer and the Trustee; and (iii) the Master Servicer assigning and selling
the master servicing shall deliver to the Trustee an officer's certificate and
an Opinion of Independent counsel, each stating that all conditions precedent to
such action under this Agreement have been completed and such action is
permitted by and complies with the terms of this Agreement. No such assignment
or delegation shall affect any liability of the Master Servicer arising out of
acts or omissions prior to the effective date thereof.

                  SECTION 7.07. Rights of the Depositor in Respect of the
                                Servicer.

                  Each of the Master Servicer and the Servicer shall afford (and
any Sub-Servicing Agreement shall provide that each Sub-Servicer shall afford)
the Depositor and the Trustee, upon reasonable notice, during normal business
hours, access to all records maintained by the Master Servicer or the Servicer
(and any such Sub-Servicer) in respect of the Servicer's rights and obligations
hereunder and access to officers of the Master Servicer or the Servicer (and
those of any such Sub-Servicer) responsible for such obligations. Upon request,
each of the Master Servicer and the Servicer shall furnish to the Depositor and
the Trustee its (and any such Sub-Servicer's) most recent financial statements
and such other information relating to the Master Servicer's or Servicer's
capacity to perform its obligations under this Agreement as it possesses (and
that any such Sub- Servicer possesses). To the extent such information is not
otherwise available to the public, the Depositor and the Trustee shall not
disseminate any information obtained pursuant to the preceding two sentences
without the Master Servicer's or the Servicer's written consent, except as
required pursuant to this Agreement or to the extent that it is appropriate to
do so (i) to its legal counsel, auditors, taxing authorities or other
governmental agencies and the Certificateholders, (ii) pursuant to any law,
rule, regulation, order, judgment, writ, injunction or decree of any court or
governmental authority having jurisdiction over the Depositor and the Trustee or
the Trust Fund, and in any case, the Depositor or the Trustee, (iii) disclosure
of any and all information that is or becomes publicly known, or information
obtained by the Trustee from sources other than the Depositor, the Servicer or
the Master Servicer, (iv) disclosure as required pursuant to this Agreement or
(v) disclosure of any and all information (A) in any preliminary or final
offering circular, registration statement or contract or other document
pertaining to the transactions contemplated by the Agreement approved in advance
by the Depositor, the Servicer or the Master Servicer or (B) to any affiliate,
independent or internal auditor, agent, employee or attorney of the Trustee
having a need to know the same, provided that the Trustee advises such recipient
of the confidential nature of the information being disclosed, shall use its
best efforts to assure the confidentiality of any such disseminated non-public
information. The Depositor may, but is not obligated to, enforce the obligations
of the Master Servicer and the Servicer under this Agreement and may, but is not
obligated to, perform, or cause a designee to perform, any defaulted obligation
of the Master Servicer or the Servicer under this Agreement or exercise the
rights of the Master Servicer or the Servicer under this Agreement; provided
that neither the Master Servicer nor the Servicer shall be relieved of any of
its obligations under this Agreement by virtue of such performance by the
Depositor or its designee. The Depositor shall not have any responsibility or
liability for any action or failure to act by the Master Servicer or the
Servicer and is not obligated to supervise the performance of the Master
Servicer or the Servicer under this Agreement or otherwise.

         under the terms of the Certificates and this Agreement which continues
         unremedied for a period of one Business Day after the date upon which
         written notice of such failure, requiring the same to be remedied,
         shall have been given to the Servicer by the Depositor or the Trustee

         remained in force undischarged or unstayed for a period of 90 days; or

                           (iv) the Servicer shall consent to the appointment of

         the required time period, its obligations under Section 3.17, 3.18 or
         3.19 which failure continues unremedied for a period of thirty (30)
         days after the date on which written notice of such failure, requiring
         the same to be remedied, shall have been given to the Servicer by any
         party to this Agreement; or

                           (vii) any failure of the Servicer to make any P&I
         Advance on any Servicer Remittance Date required to be made from its
         own funds pursuant to Section 5.03 which continues unremedied until

If a Servicer Event of Default described in clauses (i) through (vi) of this
Section shall occur, then, and in each and every such case, so long as such
Servicer Event of Default shall not have been remedied, the Depositor or the
Trustee may, and at the written direction of the Holders of Certificates
entitled to at least 51% of Voting Rights, the Trustee shall, by notice in
writing to the Servicer (and to the Depositor if given by the Trustee or to the

all of the rights and obligations of the Servicer in its capacity as Servicer
under this Agreement, to the extent permitted by law, and in and to the Mortgage
Loans and the proceeds thereof. If a Servicer Event of Default described in
clause (vii) hereof shall occur, the Trustee shall, by notice in writing to the
Servicer and the Depositor, terminate all of the rights and obligations of the
Servicer in its capacity as Servicer under this Agreement and in and to the
Mortgage Loans and the proceeds thereof. Subject to Section 8.02(b), on or after
the receipt by the Servicer of such written notice, all authority and power of
the Servicer 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, as
attorney-in-fact or otherwise, to execute and deliver, on behalf of and at the
expense of the Servicer, 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 Servicer agrees promptly (and in any event no later than ten
Business Days subsequent to such notice) to provide the Trustee with all
documents and records requested by it to enable it to assume the Servicer's
functions under this Agreement, and to cooperate with the Trustee in effecting
the termination of the Servicer's responsibilities and rights under this
Agreement, including, without limitation, the transfer within one Business Day
to the Trustee for administration by it of all cash amounts which at the time
shall be or should have been credited by the Servicer to the Collection Account
held by or on behalf of the Servicer or thereafter be received with respect to
the Mortgage Loans or any REO Property (provided, however, that the Servicer
shall continue to be 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 P&I Advances or otherwise, and shall continue to be entitled to the
benefits of Section 6.03, notwithstanding any such termination, with respect to
events occurring prior to such termination). For purposes of this Section
8.01(a), the Trustee shall not be deemed to have knowledge of a Servicer Event
of Default unless a Responsible Officer of the Trustee assigned to and working
in the Trustee's Corporate Trust Office has actual knowledge thereof or unless
written notice of any event which is in fact such a Servicer Event of Default is
received by the Trustee and such notice references the Certificates, the Trust
or this Agreement. The Trustee shall promptly notify the Rating

knowledge as provided above.

                  To the extent that the costs and expenses of the Trustee
related to the termination of the Servicer, appointment of a successor Servicer
or the transfer and assumption of the servicing by the Trustee (including,
without limitation, (i) all legal costs and expenses and all due diligence costs
and expenses associated with an evaluation of the potential termination of the
Servicer as a result of a Servicer Event of Default and (ii) all costs and
expenses associated with the complete transfer of servicing, including all
servicing files and all servicing data and the completion, correction or
manipulation of such servicing data as may be required by the successor servicer
to correct any errors or insufficiencies in the servicing data or otherwise to
enable the successor servicer to service the Mortgage Loans in accordance with
this Agreement) are not fully and timely reimbursed by the terminated Servicer,
the Trustee shall be entitled to reimbursement of such costs and expenses from
the Distribution Account.

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

                           (i) any failure on the part of the Master Servicer
         duly to observe or perform in any material respect any other of the
         covenants or agreements on the part of the Master Servicer contained in
         this Agreement, or the breach by the Master Servicer of any
         representation and warranty contained in Section 2.04, 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 by the Depositor or the Trustee or to
         the Master Servicer, the Depositor and the Trustee by the Holders of
         Certificates entitled to at least 25% of the Voting Rights; or

                           (ii) 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 or the appointment of a
         conservator or receiver or liquidator in any insolvency, readjustment
         of debt, marshalling of assets and liabilities or similar proceeding,
         or for the winding-up or liquidation of its affairs, shall have been
         entered against the Master Servicer and such decree or order shall have
         remained in force undischarged or unstayed for a period of 90 days; or

                           (iii) the Master Servicer shall consent to the
         appointment of a conservator or receiver or liquidator in any
         insolvency, readjustment of debt, marshalling 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

                           (iv) the Master 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 insolvency or
         reorganization statute, make an assignment for the benefit of its
         creditors, or voluntarily suspend payment of its obligations.

If a Master Servicer Event of Default shall occur, then, and in each and every
such case, so long as such Master Servicer Event of Default shall not have been
remedied, the Depositor or the Trustee may, and at the written direction of the
Holders of Certificates entitled to at least 51% of Voting Rights, the Trustee
shall, by notice in writing to the Master Servicer (and to the Depositor if
given by the Trustee or to the Trustee if given by the Depositor) with a copy to
each Rating Agency, terminate all of the rights and obligations of the Master
Servicer in its capacity as Master Servicer under this Agreement, to the extent
permitted by law, and in and to the Mortgage Loans and the proceeds thereof. On
or after the receipt by the Master Servicer of such written notice, all
authority and power of the Master Servicer under this Agreement, whether with
respect to the Certificates (other than as a Holder of any Certificate) or the
Mortgage Loans or otherwise including, without limitation, the compensation
payable to the Master Servicer under this Agreement, 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, as attorney-in-fact or otherwise, to
execute and deliver, on behalf of and at the expense of the Master Servicer, 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
agrees promptly (and in any event no later than ten Business Days subsequent to
such notice) to provide the Trustee with all documents and records requested by
it to enable it to assume the Master Servicer's functions under this Agreement,
and to cooperate with the Trustee in effecting the termination of the Master
Servicer's responsibilities and rights under this Agreement (provided, however,
that the Master Servicer shall continue to be entitled to receive all amounts
accrued or owing to it under this Agreement on or prior to the date of such
termination and shall continue to be entitled to the benefits of Section 7.03,
notwithstanding any such termination, with respect to events occurring prior to
such termination). For purposes of this Section 8.01(b), the Trustee shall not
be deemed to have knowledge of a Master Servicer Event of Default unless a
Responsible Officer of the Trustee assigned to and working in the Trustee's
Corporate Trust Office has actual knowledge thereof or unless written notice of
any event which is in fact such a Master Servicer Event of Default is received
by the Trustee and such notice references the Certificates, the Trust or this
Agreement. The Trustee shall promptly notify the Rating Agencies of the
occurrence of a Master Servicer Event of Default of which it has knowledge as
provided above.

                  To the extent that the costs and expenses of the Trustee
related to the termination of the Master Servicer, appointment of a successor
Master Servicer or the transfer and assumption of the master servicing by the
Trustee (including, without limitation, (i) all legal costs and expenses and all
due diligence costs and expenses associated with an evaluation of the potential
termination of the Master Servicer as a result of a Master Servicer Event of
Default and (ii) all costs and expenses associated with the complete transfer of
the master servicing, including all servicing files and all servicing data and
the completion, correction or manipulation of such servicing data as may be
required by the successor Master Servicer to correct any errors or
insufficiencies in the servicing data or otherwise to enable the successor
Master Servicer to master service the Mortgage Loans in accordance with this
Agreement) are not fully and timely reimbursed by the terminated Master
Servicer, the Trustee shall be entitled to reimbursement of such costs and
expenses from the Distribution Account.

<PAGE>

                  (a) On and after the time the Servicer receives a notice of
termination, the Trustee shall be the successor in all respects to the Servicer
in its capacity as Servicer under this Agreement and the transactions set forth
or provided for herein, and all the responsibilities, duties and liabilities
relating thereto and arising thereafter shall be assumed by the Trustee (except
for any representations or warranties of the Servicer under this Agreement, the
responsibilities, duties and liabilities contained in Section 2.03 and the
obligation to deposit amounts in respect of losses pursuant to Section 3.23(c))
by the terms and provisions hereof including, without limitation, the Servicer's
obligations to make P&I Advances pursuant to Section 5.03; provided, however,
that if the Trustee is prohibited by law or regulation from obligating itself to
make advances regarding delinquent mortgage loans, then the Trustee shall not be
obligated to make P&I Advances pursuant to Section 5.03; and provided further,
that any failure to perform such duties or responsibilities caused by the
Servicer's failure to provide information required by Section 7.01 shall not be
considered a default by the Trustee as successor to the Servicer hereunder. As
compensation therefor, the Trustee shall be entitled to the Servicing Fee and
all other compensation to which the Servicer would have been entitled if it had
continued to act hereunder.

                  (b)(1) All servicing transfer costs (including, without
limitation, servicing transfer costs of the type described in Section 8.02(a)
and incurred by the Trustee, the Master Servicer and any successor Servicer
under paragraph (b)(2) below) shall be paid by the terminated Servicer upon
presentation of reasonable documentation of such costs, and if such predecessor
or initial Servicer, as applicable, defaults in its obligation to pay such
costs, the successor Servicer, the Master Servicer and the Trustee shall be
entitled to reimbursement therefor from the assets of the Trust Fund.

                  (2) No appointment of a successor to the Servicer under this
Agreement shall be effective until the assumption by the successor of all of the
Servicer's responsibilities, duties and liabilities hereunder. In connection
with such appointment and assumption described herein, the Trustee may make such
arrangements for the compensation of such successor out of payments on Mortgage
Loans as it and such successor shall agree; provided, however, that no such
compensation shall be in excess of that permitted the Servicer as such
hereunder. The Depositor, the Trustee and such successor shall take such action,
consistent with this Agreement, as shall be necessary to effectuate any such
succession. Pending appointment of a successor to the Servicer under this
Agreement, the Trustee shall act in such capacity as hereinabove provided.

                  (c) (1) In the event of a Servicer Event of Default,
notwithstanding anything to the contrary above, the Trustee and the Depositor
hereby agree that upon delivery to the Trustee by the Servicing Rights Pledgee
of a letter signed by the Servicer within ten Business Days of when notification
of such event shall have been provided to the Trustee, whereunder the Servicer
shall resign as Servicer under this Agreement, the Trustee shall appoint the
Servicing Rights Pledgee or its designee as successor Servicer, provided that at
the time of such appointment, the Servicing Rights Pledgee or such designee
meets the requirements of a successor Servicer set forth in paragraph (c)(2)
below and the Servicing Rights Pledgee or such designee agrees to be subject to
the terms of this Agreement.

                  (2) In the event that the Servicing Rights Pledgee does not
deliver to the Trustee the letter described in preceding paragraph within the
time period specified therein, the Trustee shall

                                     -140-
<PAGE>

give notice thereof in writing to the Master Servicer and upon receipt of such
notice, the Master Servicer shall be the successor in all respects to the
Servicer in its capacity as Servicer under this Agreement and the transactions
set forth or provided for herein, and all the responsibilities, duties and
liabilities relating thereto and arising thereafter shall be assumed by the
Master Servicer (except for any representations or warranties of the Servicer
under this Agreement, the responsibilities, duties and liabilities contained in
Section 2.03 and the obligation to deposit amounts in respect of losses pursuant
to Section 3.23(c)) by the terms and provisions hereof including, without
limitation, the Servicer's obligations to make P&I Advances pursuant to Section
5.03; provided, however, that (1) it is understood and acknowledged by the
parties hereto that there will be a period of transition (not to exceed 90 days)
before the actual servicing functions can be fully transferred to the Master
Servicer or any successor Servicer appointed in accordance with the following
provisions and (2) any failure to perform such duties or responsibilities caused
by the Servicer's failure to provide information required by Section 8.01 shall
not be considered a default by the Master Servicer as successor to the Servicer
hereunder. As compensation therefor, the Master Servicer shall be entitled to
the Servicing Fee and all funds relating to the Mortgage Loans to which the
Servicer would have been entitled if it had continued to act hereunder.
Notwithstanding the above and subject to the immediately following paragraph,
the Master Servicer may, if it shall be unwilling to so act, or shall, if it is
unable to so act promptly appoint or petition a court of competent jurisdiction
to appoint, an established mortgage loan servicing institution acceptable to
each Rating Agency and having a net worth of not less than $15,000,000, as the
successor to the Servicer under this Agreement in the assumption of all or any
part of the responsibilities, duties or liabilities of the Servicer under this
Agreement.

                  (d) In connection with the termination or resignation of the
Servicer hereunder, (i) the successor Servicer, including the Trustee or the
Master Servicer, if the Trustee or the Master Servicer is acting as successor
Servicer, shall represent and warrant that it is a member of MERS in good
standing and shall agree to comply in all material respects with the rules and
procedures of MERS in connection with the servicing of the Mortgage Loans that
are registered with MERS, in which case the predecessor Servicer shall cooperate
with the successor Servicer in causing MERS to revise its records to reflect the
transfer of servicing to the successor Servicer as necessary under MERS' rules
and regulations, and (ii) the predecessor Servicer shall cooperate with the
successor Servicer in causing MERS to transfer the servicing of such Mortgage
Loan on the MERS(R) System to the successor Servicer. The predecessor Servicer
shall file or cause to be filed any such assignment in the appropriate recording
office. The predecessor Servicer shall bear any and all fees of MERS, costs of
preparing any assignments of Mortgage, and fees and costs of filing any
assignments of Mortgage that may be required under this Section 8.02(d).

                  SECTION 8.03. Notification to Certificateholders.

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

                  (b) Not later than the later of 60 days after the occurrence
of any event, which constitutes or which, with notice or lapse of time or both,
would constitute a Servicer Event of

                                     -141-
<PAGE>

Default or a Master Servicer Event of Default or five days after a Responsible
Officer of the Trustee becomes aware of the occurrence of such an event, the
Trustee shall transmit by mail to all Holders of Certificates notice of each
such occurrence, unless such default or Servicer Event of Default or Master
Servicer Event of Default shall have been cured or waived.

                  SECTION 8.04. Waiver of Servicer Events of Default.

                  The Holders representing at least 66% of the Voting Rights
evidenced by all Classes of Certificates affected by any default, Servicer Event
of Default or Master Servicer Event of Default hereunder may waive such default,
Servicer Event of Default or Master Servicer Event of Default; provided,
however, that a default, Servicer Event of Default under clause (i) or (vi) of
Section 7.01 may be waived only by all of the Holders of the Regular
Certificates. Upon any such waiver of a default, Servicer Event of Default or
Master Servicer Event of Default, such default, Servicer Event of Default or
Master Servicer 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 default, Servicer Event of Default or Master Servicer
Event of Default or impair any right consequent thereon except to the extent
expressly so waived.

                                   ARTICLE IX

             CONCERNING THE TRUSTEE AND THE SECURITIES ADMINISTRATOR

                  SECTION 9.01. Duties of Trustee and Securities Administrator.

                  The Trustee, prior to the occurrence of a Master Servicer
Event of Default and after the curing or waiver of all Master Servicer Events of
Default which may have occurred, and the Securities Administrator each undertake
to perform such duties and only such duties as are specifically set forth in
this Agreement as duties of the Trustee and the Securities Administrator,
respectively. During the continuance of a Master Servicer Event of Default, 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 its exercise as a
prudent person would exercise or use under the circumstances in the conduct of
such person's own affairs. Any permissive right of the Trustee enumerated in
this Agreement shall not be construed as a duty.

                  Each of the Trustee and the Securities Administrator, upon
receipt of all resolutions, certificates, statements, opinions, reports,
documents, orders or other instruments furnished to it, which are specifically
required to be furnished pursuant to any provision of this Agreement, shall
examine them to determine whether they conform to the requirements of this
Agreement. If any such instrument is found not to conform to the requirements of
this Agreement in a material manner, the Trustee or the Securities
Administrator, as the case may be, shall take such action as it deems
appropriate to have the instrument corrected, and if the instrument is not
corrected to its satisfaction, the Securities Administrator will provide notice
to the Trustee thereof and the Trustee will provide notice to the
Certificateholders.

                  The Trustee shall promptly remit to the Servicer any
complaint, claim, demand, notice or other document (collectively, the "Notices")
delivered to the Trustee as a consequence of the assignment of any Mortgage Loan
hereunder and relating to the servicing of the Mortgage Loans; provided than any
such notice (i) is delivered to the Trustee at is Corporate Trust Office, (ii)
contains information sufficient to permit the Trustee to make a determination
that the real property to which such document relates is a Mortgaged Property.
The Trustee shall have no duty hereunder with respect to any Notice it may
receive or which may be alleged to have been delivered to or served upon it
unless such Notice is delivered to it or served upon it at its Corporate Trust
Office and such Notice contains the information required pursuant to clause (ii)
of the preceding sentence.

                  The Trustee agrees to notify the Master Servicer in writing no
later than 5:00 pm (Eastern Time) on each Servicer Remittance Date of the
aggregate dollar amount of the funds received by the Trustee from the Servicer
on such Servicer Remittance Date and any other information reasonably requested
by the Master Servicer, so as to enable the Master Servicer to make the
reconciliations and verifications required to be made by it pursuant to Sections
4.01 and 4.21.

                  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 a Master Servicer
                  Event of Default, and after the curing or waiver of all such
                  Master Servicer Events of Default which may have occurred with
                  respect to the Trustee and at all times with respect to the
                  Securities Administrator, the duties and obligations of the
                  Trustee shall be determined solely by the express provisions
                  of this Agreement, neither the Trustee nor the Securities
                  Administrator shall 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 or the Securities
                  Administrator and, in the absence of bad faith on the part of
                  the Trustee or the Securities Administrator, respectively, the
                  Trustee or the Securities Administrator, respectively, 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 or the
                  Securities Administrator, respectively, that conform to the
                  requirements of this Agreement;

                           (ii) Neither the Trustee nor the Securities
                  Administrator shall be liable for an error of judgment made in
                  good faith by a Responsible Officer or Responsible Officers of
                  the Trustee or an officer or officers of the Securities
                  Administrator, respectively, unless it shall be proved that
                  the Trustee or the Securities Administrator, respectively, was
                  negligent in ascertaining the pertinent facts; and

                           (iii) Neither the Trustee nor the Securities
                  Administrator shall be liable with respect to any action
                  taken, suffered or omitted to be taken by it in good faith in
                  accordance with the direction of the 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 the Securities
                  Administrator or exercising any trust or power conferred upon
                  the Trustee or the Securities Administrator under this
                  Agreement.

                                Administrator.

                  (a) Except as otherwise provided in Section 8.01:

                           (i) The Trustee and the Securities Administrator may
                  request and rely upon and shall be protected in acting or
                  refraining from acting upon any resolution, Officers'
                  Certificate, certificate of auditors or any other certificate,

                  reasonably believed by it to be genuine and to have been
                  signed or presented by the proper party or parties;

                           (ii) The Trustee and the Securities Administrator may
                  consult with counsel of its selection and any 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 with such advice or Opinion of Counsel;

                           (iii) Neither the Trustee nor the Securities
                  Administrator shall be under any obligation to exercise any of
                  the trusts or powers vested in it by this Agreement or to
                  institute, conduct or defend any litigation hereunder or in

                  the Certificateholders, pursuant to the provisions of this
                  Agreement, unless such Certificateholders shall have offered
                  to the Trustee or the Securities Administrator, as the case
                  may be, reasonable security or indemnity satisfactory to it
                  against the costs, expenses and liabilities which may be
                  incurred therein or thereby; nothing contained herein shall,

                  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 the Holders of Certificates entitled to at least 25% of the

                  powers hereunder or perform any duties hereunder either
                  directly or by or through agents or attorneys and the Trustee

                  the part of any agent or attorney appointed with due care by
                  it hereunder;

                           (vii) The Trustee shall not be liable for any loss

                  references the Certificates and this Agreement; and

                           (ix) the rights, privileges, protections, immunities
                  and benefits given to the Trustee, including, without
                  limitation, its right to be indemnified, are extended to, and
                  shall be enforceable by, each agent, custodian and other
                  Person employed to act hereunder.

                  (b) All rights of action under this Agreement or under any of
the Certificates, enforceable by the Trustee, may be enforced by it without the

                                for Certificates or Mortgage Loans.

than the signature of the Trustee, the authentication of the Trustee on the
Certificates, the acknowledgments of the Trustee contained in Article II and the
representations and warranties of the Trustee in Section 9.12) shall be taken as
the statements of the Depositor and neither the Trustee nor the Securities
Administrator assumes any responsibility for their correctness. Neither the
Trustee nor the Securities Administrator makes any representations or warranties
as to the validity or sufficiency of this Agreement (other than as specifically
set forth in Section 9.12) or of the Certificates (other than the signature of
the Trustee and authentication of the Trustee on the Certificates) or of any
Mortgage Loan or related document. The Trustee shall not be accountable for the
use or application by the Depositor of any of the Certificates or of the
proceeds of such Certificates, or for the use or application of any funds paid

                  Each of the Trustee and the Securities Administrator in its
individual capacity or any other capacity may become the owner or pledgee of
Certificates and may transact business with other interested parties and their
Affiliates with the same rights it would have if it were not Trustee or the
Securities Administrator.

                  SECTION 9.05. Fees and Expenses of Trustee and Securities
                                Administrator.

                  The fees of the Trustee and the Securities Administrator
hereunder and of Wells Fargo under the Custodial Agreement shall be paid in
accordance with a side letter agreement with the Master Servicer and at the sole
expense of the Master Servicer. In addition, the Trustee, the Securities
Administrator, the Custodian and any director, officer, employee or agent of the
Trustee, the Securities Administrator and the Custodian shall be indemnified by
the Trust and held harmless against any loss, liability or expense (including
reasonable attorney's fees and expenses) incurred by the Trustee, the Custodian
or the Securities Administrator in connection with any claim or legal action or
any pending or threatened claim or legal action arising out of or in connection
with the acceptance or administration of its respective obligations and duties
under this Agreement, including the Cap Contracts and any and all other
agreements related hereto, other than any loss, liability or expense (i) for
which the Trustee is indemnified by the Master Servicer or the Servicer, (ii)
that constitutes a specific liability of the Trustee or the Securities
Administrator pursuant to Section 11.01(g) or (iii) any loss, liability or
expense incurred by reason of willful misfeasance, bad faith or negligence in
the performance of duties hereunder by the Trustee or the Securities
Administrator reason of reckless disregard of obligations and duties hereunder.
In no event shall the Trustee or the Securities Administrator be liable for
special, indirect or consequential loss or damage of any kind whatsoever
(including but not limited to lost profits), even if it has been advised of the
likelihood of such loss or damage and regardless of the form of action. The
Master Servicer agrees to indemnify the Trustee, from, and hold the Trustee
harmless against, any loss, liability or expense (including reasonable
attorney's fees and expenses) incurred by the Trustee by reason of the Master
Servicer's willful misfeasance, bad faith or gross negligence in the performance
of its duties under this Agreement or by reason of the Master Servicer's
reckless disregard of its obligations and duties under this Agreement. Such
indemnity shall survive the termination or discharge of this Agreement and the
resignation or removal of the Trustee. Any payment hereunder made by the Master
Servicer to the Trustee shall be from the Master Servicer's own funds, without
reimbursement from REMIC I therefor.

                  SECTION 9.06. Eligibility Requirements for Trustee and
                                Securities Administrator.

business under the laws of any state or the United States of America, authorized
under such laws to exercise corporate trust powers, having a combined capital
and surplus of at least $50,000,000 (or a member of a bank holding company whose
capital and surplus is at least $50,000,000) and subject to supervision or
examination by federal or state authority. If such corporation or association
publishes reports of conditions at least annually, pursuant to law or to the
requirements of the aforesaid supervising or examining authority, then for the
purposes of this

Administrator, as applicable, shall resign immediately in the manner and with
the effect specified in Section 9.07.

                                Securities Administrator.

                  The Trustee and the Securities Administrator may at any time
resign and be discharged from the trust hereby created by giving written notice
thereof to the Depositor, to the Master Servicer, to the Securities
Administrator (or the Trustee, if the Securities Administrator resigns) and to
the Certificateholders. Upon receiving such notice of resignation, the Depositor
shall promptly appoint a successor trustee or successor securities administrator
by written instrument, in duplicate, which instrument shall be delivered to the
resigning Trustee or Securities Administrator, as applicable, and to the
successor trustee or successor securities administrator, as applicable. A copy
of such instrument shall be delivered to the Certificateholders, the Trustee,
the Securities Administrator and the Master Servicer by the Depositor. If no
successor trustee or successor securities administrator shall have been so
appointed and have accepted appointment within 30 days after the giving of such
notice of resignation, the resigning Trustee or Securities Administrator, as the
case may be, may, at the expense of the Trust Fund, petition any court of
competent jurisdiction for the appointment of a successor trustee, successor
securities administrator, Trustee or Securities Administrator, as applicable.

                  If at any time the Trustee or the Securities Administrator
shall cease to be eligible in accordance with the provisions of Section 9.06 and
shall fail to resign after written request therefor by the Depositor, or if at
any time the Trustee or the Securities Administrator shall become incapable of
acting, or shall be adjudged bankrupt or insolvent, or a receiver of the Trustee
or the Securities Administrator or of its property shall be appointed, or any
public officer shall take charge or control of the Trustee or the Securities
Administrator or of its property or affairs for the purpose of rehabilitation,
conservation or liquidation, then the Depositor may remove the Trustee or the
Securities Administrator, as applicable and appoint a successor trustee or
successor securities administrator, as applicable, by written instrument, in
duplicate, which instrument shall be delivered to the Trustee or the Securities
Administrator so removed and to the successor trustee or successor securities
administrator. A copy of such instrument shall be delivered to the
Certificateholders, the Trustee, the Securities Administrator and the Master
Servicer by the Depositor.

                  The Holders of Certificates entitled to at least 51% of the
Voting Rights may at any time remove the Trustee or the Securities Administrator
and appoint a successor trustee or successor securities administrator 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 Depositor, one complete set to the Trustee or the Securities
Administrator so removed and one complete set to the successor so appointed. A
copy of such instrument shall be delivered to the Certificateholders, the
Trustee (in the case of the removal of the Securities Administrator), the
Securities Administrator (in the case of the removal of the Trustee) and the
Master Servicer by the Depositor.

                  Any resignation or removal of the Trustee or the Securities
Administrator and appointment of a successor trustee or successor securities
administrator pursuant to any of the provisions of this Section shall not become
effective until acceptance of appointment by the successor trustee or successor
securities administrator, as applicable, as provided in Section 8.08.

                  Notwithstanding anything to the contrary contained herein, the
Master Servicer and the Securities Administrator shall at all times be the same
Person.

                  SECTION 9.08. Successor Trustee or Securities Administrator.

                  Any successor trustee or successor securities administrator
appointed as provided in Section 9.07 shall execute, acknowledge and deliver to
the Depositor and its predecessor trustee or predecessor securities
administrator an instrument accepting such appointment hereunder, and thereupon
the resignation or removal of the predecessor trustee or predecessor securities
administrator shall become effective and such successor trustee or successor
securities administrator 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 or
securities administrator herein. The predecessor trustee or predecessor
securities administrator shall deliver to the successor trustee or successor
securities administrator all Mortgage Loan Documents and related documents and
statements to the extent held by it hereunder, as well as all moneys, held by it
hereunder, and the Depositor and the predecessor trustee or predecessor
securities administrator shall execute and deliver such instruments and do such
other things as may reasonably be required for more fully and certainly vesting
and confirming in the successor trustee or successor securities administrator
all such rights, powers, duties and obligations.

                  No successor trustee or successor securities administrator
shall accept appointment as provided in this Section unless at the time of such
acceptance such successor trustee or successor securities administrator shall be
eligible under the provisions of Section 8.06 and the appointment of such
successor trustee or successor securities administrator shall not result in a
downgrading of any Class of Certificates by any Rating Agency, as evidenced by a
letter from each Rating Agency.

                  Upon acceptance of appointment by a successor trustee or
successor securities administrator as provided in this Section, the Depositor
shall mail notice of the succession of such trustee hereunder to all Holders of
Certificates at their addresses as shown in the Certificate Register. If the
Depositor fails to mail such notice within 10 days after acceptance of
appointment by the successor trustee or successor securities administrator, the
successor trustee or successor securities administrator shall cause such notice

                  SECTION 9.09. Merger or Consolidation of Trustee or Securities
                                Administrator.

                  Any corporation or association into which the Trustee or the
Securities Administrator may be merged or converted or with which it may be
consolidated or any corporation or association resulting from any merger,
conversion or consolidation to which the Trustee or the Securities Administrator
shall be a party, or any corporation or association succeeding to the business
of the Trustee or the Securities Administrator shall be the successor of the
Trustee or the Securities

Administrator hereunder, provided such corporation or association shall be
eligible under the provisions of Section 8.06, 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 9.10. Appointment of Co-Trustee or Separate Trustee.

                  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 REMIC I or property securing the same may at the time be located,
the Trustee 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 REMIC I, and to vest in such Person or Persons, in such
capacity, and for the benefit of the Holders of the Certificates, such title to
REMIC I, or any part thereof, and, subject to the other provisions of this
Section 9.10, such powers, duties, obligations, rights and trusts as the Trustee
may consider necessary or desirable. No co-trustee or separate trustee hereunder
shall be required to meet the terms of eligibility as a successor trustee under
Section 9.06 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.

                  In the case of any appointment of a co-trustee or separate
trustee pursuant to this Section 9.10 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 by the Trustee (whether as
Trustee hereunder or as successor to a defaulting Master Servicer hereunder),
the Trustee shall be incompetent or unqualified to perform such act or acts, in
which event such rights, powers, duties and obligations (including the holding
of title to REMIC I 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.

                  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 IX. Each separate trustee and co-trustee, upon
its acceptance of the trust 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.

                  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 die, 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 or co-trustee.

Servicer, the Securities Administrator and the Depositor as applicable, as of
the Closing Date, that:

                  (i) It is a banking corporation duly organized, validly
         existing and in good standing under the laws of the State of New York.

                  (ii) The execution and delivery of this Agreement by it, and
         the performance and compliance with the terms of this Agreement by it,
         will not violate its articles of association 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) It has the full power and authority 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.

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

                  (v) It 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 its good faith and reasonable judgment, is likely
         to affect materially and adversely either the ability of it to perform
         its obligations under this Agreement or its financial condition.

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

under this Agreement or the Trustee and the Securities Administrator have
received an Opinion of Counsel, addressed to the them (at the expense of the
party seeking to take such action but in no event at the expense of the Trustee
or the Securities Administrator) to the effect that the contemplated action will
not, with respect to any Trust REMIC, endanger such status or result in the
imposition of such a tax, nor (iii) shall the Securities Administrator take or
fail to take any action (whether or not authorized hereunder) as to which the
Trustee has advised it in writing that it has received an Opinion of Counsel to
the effect that an Adverse REMIC Event could occur with respect to such action;

any such action as to which the Trustee has advised it in writing that an
Adverse REMIC Event could occur. The Trustee may consult with counsel to make

Fund will not cause the related REMIC to fail to qualify as a REMIC at any time
that any Certificates are outstanding or subject such REMIC to any tax under the
REMIC Provisions or other applicable provisions of federal, state and local law
or ordinances.

                  SECTION 12.09.            Grant of Security Interest.

                  It is the express intent of the parties hereto that the
conveyance of the Mortgage Loans by the Depositor to the Trustee, on behalf of
the Trust and for the benefit of the Certificateholders, be, and be construed
as, a sale of the Mortgage Loans by the Depositor and not a pledge of the
Mortgage Loans to secure a debt or other obligation of the Depositor. However,
in the event that, notwithstanding the aforementioned intent of the parties, the
Mortgage Loans are held to be property of the Depositor, then, (a) it is the
express intent of the parties that such conveyance be deemed a pledge of the
Mortgage Loans by the Depositor to the Trustee, on behalf of the Trust and for
the benefit of the Certificateholders, to secure a debt or other obligation of
the Depositor and (b)(1) this Agreement shall also be deemed to be a security
agreement within the meaning of Articles 8 and 9 of the Uniform Commercial Code
as in effect from time to time in the State of New York; (2) the conveyance
provided for in Section 2.01 shall be deemed to be a grant by the Depositor to
the Trustee, on behalf of the Trust and for the benefit of the
Certificateholders, of a security interest in all of the Depositor's right,
title and interest in and to the Mortgage Loans and all amounts payable to the
holders of the Mortgage Loans in accordance with the terms thereof and all
proceeds of the conversion, voluntary or involuntary, of the foregoing into
cash, instruments, securities or other property, including without limitation
all amounts, other than investment earnings, from time to time

                                     -163-
<PAGE>

held or invested in the Collection Account and the Distribution Account, whether
in the form of cash, instruments, securities or other property; (3) the
obligations secured by such security agreement shall be deemed to be all of the
Depositor's obligations under this Agreement, including the obligation to
provide to the Certificateholders the benefits of this Agreement relating to the
Mortgage Loans and the Trust Fund; and (4) notifications to persons holding such
property, and acknowledgments, receipts or confirmations from persons holding
such property, shall be deemed notifications to, or acknowledgments, receipts or
confirmations from, financial intermediaries, bailees or agents (as applicable)
of the Trustee for the purpose of perfecting such security interest under
applicable law. Accordingly, the Depositor hereby grants to the Trustee, on
behalf of the Trust and for the benefit of the Certificateholders, a security
interest in the Mortgage Loans and all other property described in clause (2) of
the preceding sentence, for the purpose of securing to the Trustee the
performance by the Depositor of the obligations described in clause (3) of the
preceding sentence. Notwithstanding the foregoing, the parties hereto intend the
conveyance pursuant to Section 2.01 to be a true, absolute and unconditional
sale of the Mortgage Loans and assets constituting the Trust Fund by the
Depositor to the Trustee, on behalf of the Trust and for the benefit of the
Certificateholders.

                  SECTION 12.10.            Survival of Indemnification.

                  Any and all indemnities to be provided by any party to this
Agreement shall survive the termination and resignation of any party hereto and

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

notation of such consent is made upon this Certificate. The Agreement also
permits the amendment thereof, in certain limited circumstances, without the
consent of the Holders of any of the Certificates.

                  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 or agencies appointed by the Trustee as provided in
the Agreement, duly endorsed by, or accompanied by an assignment in the form
below or other written instrument of transfer in form satisfactory to the
Trustee duly executed by, the Holder hereof or such Holders attorney duly
authorized in writing, and thereupon one or more new Certificates of the same

                                      A-1-3

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

                  No service charge will be made for any such registration of
transfer or exchange of Certificates, but the Trustee 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.

                  The Depositor, the Master Servicer, the Trustee, the
Securities Administrator, the Servicer and any agent of the Depositor, the
Master Servicer, the Trustee, the Securities Administrator or the Servicer 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
Trustee, the Securities Administrator, the Servicer nor any such agent shall be
affected by notice to the contrary.

                  The obligations created by the Agreement and the Trust Fund
created thereby shall terminate upon payment to the Certificateholders of all
amounts held by the Trustee and required to be paid to them pursuant to the
Agreement following the earlier of (i) the final payment or other liquidation
(or any advance with respect thereto) of the last Mortgage Loan remaining in
REMIC I and (ii) the purchase by the party designated in the Agreement at a
price determined as provided in the Agreement from REMIC I of all the Mortgage
Loans and all property acquired in respect of such Mortgage Loans. The Agreement
permits, but does not require, the party designated in the Agreement to purchase
from REMIC I all the Mortgage Loans and all property acquired in respect of any
Mortgage Loan at a price determined as provided in the Agreement. 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 Loans at the time of purchase being less than 10% of the aggregate
principal balance of the Mortgage Loans as of the Cut-off Date.

                  The recitals contained herein shall be taken as statements of
the Depositor and the Trustee does not assume responsibility for their
correctness.

                  Unless the certificate of authentication hereon has been
executed by the Trustee, by manual signature, this Certificate shall not be
entitled to any benefit under the Agreement or be valid for any purpose.

provided, the amendment thereof and the modification of the rights and
obligations of the Depositor, the Master Servicer, the Trustee, the Securities
Administrator, the Servicer and the rights of the Certificateholders under the

same Class in authorized denominations evidencing the same aggregate Percentage
Interest will be issued to the designated transferee or transferees.

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

                  Any transferee of this Certificate shall be deemed to make the
representations set forth in Section 6.02(c) of the Agreement.

                  No service charge will be made for any such registration of
transfer or exchange of Certificates, but the Trustee 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.

                  The Depositor, the Master Servicer, the Trustee, the
Securities Administrator, the Servicer and any agent of the Depositor, the
Master Servicer, the Trustee, the Securities Administrator or the Servicer 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
Trustee, the Securities Administrator, the Servicer nor any such agent shall be
affected by notice to the contrary.

                  The obligations created by the Agreement and the Trust Fund
created thereby shall terminate upon payment to the Certificateholders of all
amounts held by the Trustee and required to be paid to them pursuant to the
Agreement following the earlier of (i) the final payment or other liquidation
(or any advance with respect thereto) of the last Mortgage Loan remaining in
REMIC I and (ii) the purchase by the party designated in the Agreement at a
price determined as provided in the Agreement from REMIC I of all the Mortgage
Loans and all property acquired in respect of such Mortgage Loans. The Agreement
permits, but does not require, the party designated in the Agreement to purchase
from REMIC I all the Mortgage Loans and all property acquired in respect of any
Mortgage Loan at a price determined as provided in the Agreement. 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 Loans at the time of purchase being less than 10% of the aggregate
principal balance of the Mortgage Loans as of the Cut-off Date.

                  The recitals contained herein shall be taken as statements of
the Depositor and the Trustee does no assume responsibility for their
correctness.

                  Unless the certificate of authentication hereon has been
executed by the Trustee by manual signature, this Certificate shall not be
entitled to any benefit under the Agreement or be valid for any purpose.

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 Collection Account and the Distribution Account
may be made from time to time for purposes other than distributions to
Certificateholders, such purposes including reimbursement of advances made, or
certain expenses incurred, with respect to the Mortgage Loans.

                  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 Trustee, the Securities
Administrator, the Servicer and the rights of the Certificateholders under the
Agreement at any time by the Depositor, the Master Servicer, the Trustee, the
Securities Administrator and the Servicer with the consent of the Holders of
Certificates entitled to at least 66% of the Voting Rights. 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, without the
consent of the Holders of any of the Certificates.

                  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 or agencies appointed by the Trustee as provided in
the Agreement, duly endorsed by, or accompanied by an assignment in the form
below or other written instrument of transfer in form satisfactory to the
Trustee duly executed by, the Holder hereof or such Holder's attorney duly
authorized in writing, and thereupon one or more new Certificates of the same
Class in authorized denominations evidencing the same aggregate Percentage
Interest will be issued to the designated transferee or transferees.

                  No transfer of this Certificate shall be made unless the
transfer is made pursuant to an effective registration statement under the
Securities Act of 1933, as amended (the "1933 Act"), and an effective
registration or qualification under applicable state securities laws, or is made
in a transaction that does not require such registration or qualification. In
the event that such a transfer of this Certificate is to be made without
registration or qualification, the Trustee shall require receipt

                                      A-4-4

<PAGE>

of (i) if such transfer is purportedly being made in reliance upon Rule 144A
under the 1933 Act, written certifications from the Holder of the Certificate
desiring to effect the transfer, and from such Holder's prospective transferee,
substantially in the forms attached to the Agreement as Exhibit B-1, and (ii) in
all other cases, an Opinion of Counsel satisfactory to it that such transfer may
be made without such registration or qualification (which Opinion of Counsel
shall not be an expense of the Trust Fund or of the Depositor, the Trustee, the
Master Servicer or the Securities Administrator in their respective capacities
as such), together with copies of the written certification(s) of the Holder of
the Certificate desiring to effect the transfer and/or such Holder's prospective
transferee upon which such Opinion of Counsel is based. Neither the Depositor
nor the Trustee is obligated to register or qualify the Class of Certificates
specified on the face hereof under the 1933 Act or any other securities law or
to take any action not otherwise required under the Agreement to permit the
transfer of such Certificates without registration or qualification. Any Holder
desiring to effect a transfer of this Certificate shall be required to indemnify
the Trustee, the Depositor, the Master Servicer and the Securities Administrator
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 Certificate to a Plan subject to ERISA or
Section 4975 of the Code, any Person acting, directly or indirectly, on behalf
of any such Plan or any Person using "Plan Assets" to acquire this Certificate
shall be made except in accordance with Section 6.02(c) of the Agreement.

                  The Certificates are issuable in fully registered form only
without coupons in Classes and denominations representing Percentage Interests
specified in the Agreement. As provided in the Agreement and subject to certain
limitations therein set forth, the Certificates are exchangeable for new
Certificates of the same Class in authorized denominations evidencing the same
aggregate Percentage Interest, as requested by the Holder surrendering the same.
No service charge will be made for any such registration of transfer or exchange
of Certificates, but the Trustee 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.

                  The Depositor, the Master Servicer, the Trustee, the
Securities Administrator, the Servicer and any agent of the Depositor, the
Master Servicer, the Trustee, the Securities Administrator or the Servicer 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
Trustee, the Securities Administrator, the Servicer nor any such agent shall be
affected by notice to the contrary.

                  The obligations created by the Agreement and the Trust Fund
created thereby shall terminate upon payment to the Certificateholders of all
amounts held by the Trustee and required to be paid to them pursuant to the
Agreement following the earlier of (i) the final payment or other liquidation
(or any advance with respect thereto) of the last Mortgage Loan remaining in
REMIC I and (ii) the purchase by the party designated in the Agreement at a
price determined as provided in the Agreement from REMIC I of all the Mortgage
Loans and all property acquired in respect of such Mortgage Loans. The Agreement
permits, but does not require, the party designated in the Agreement to purchase
from REMIC I all the Mortgage Loans and all property acquired in respect of any
Mortgage Loan at a price determined as provided in the Agreement. The exercise
of such right will effect early retirement of the Certificates; however, such
right to purchase is subject to the

                                      A-4-5

aggregate Stated Principal Balance of the Mortgage Loans at the time of purchase
being less than 10% of the aggregate principal balance of the Mortgage Loans as
of the Cut-off Date.

                  The recitals contained herein shall be taken as statements of
the Depositor and the Trustee assumes no responsibility for their correctness.

                  Unless the certificate of authentication hereon has been
executed by the Trustee, by manual signature, this Certificate shall not be
entitled to any benefit under the Agreement or be valid for any purpose.

                  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 or agencies appointed by the Trustee as provided in
the Agreement, duly endorsed by, or accompanied by an assignment in the form
below or other written instrument of transfer in form satisfactory to the
Trustee duly executed by, the Holder hereof or such Holder's attorney duly
authorized in writing, and thereupon one or more new Certificates of the same
Class in authorized denominations evidencing the same aggregate Percentage
Interest will be issued to the designated transferee or transferees.

                  No transfer of this Certificate shall be made unless the
transfer is made pursuant to an effective registration statement under the
Securities Act of 1933, as amended (the "1933 Act"), and an effective
registration or qualification under applicable state securities laws, or is made
in a transaction that does not require such registration or qualification. In
the event that such a transfer of this Certificate is to be made without
registration or qualification, the Trustee shall require receipt

                                      A-5-4

<PAGE>

of (i) if such transfer is purportedly being made in reliance upon Rule 144A
under the 1933 Act, written certifications from the Holder of the Certificate
desiring to effect the transfer, and from such Holder's prospective transferee,
substantially in the forms attached to the Agreement as Exhibit B-1, and (ii) in
all other cases, an Opinion of Counsel satisfactory to it that such transfer may
be made without such registration or qualification (which Opinion of Counsel
shall not be an expense of the Trust Fund or of the Depositor, the Trustee, the
Master Servicer or the Securities Administrator in their respective capacities
as such), together with copies of the written certification(s) of the Holder of
the Certificate desiring to effect the transfer and/or such Holder's prospective
transferee upon which such Opinion of Counsel is based. Neither the Depositor
nor the Trustee is obligated to register or qualify the Class of Certificates
specified on the face hereof under the 1933 Act or any other securities law or
to take any action not otherwise required under the Agreement to permit the
transfer of such Certificates without registration or qualification. Any Holder
desiring to effect a transfer of this Certificate shall be required to indemnify
the Trustee, the Depositor, the Master Servicer and the Securities Administrator
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 Certificate to a Plan subject to ERISA or
Section 4975 of the Code, any Person acting, directly or indirectly, on behalf
of any such Plan or any Person using "Plan Assets" to acquire this Certificate
shall be made except in accordance with Section 6.02(c) of the Agreement.

                  The Certificates are issuable in fully registered form only
without coupons in Classes and denominations representing Percentage Interests
specified in the Agreement. As provided in the Agreement and subject to certain
limitations therein set forth, the Certificates are exchangeable for new
Certificates of the same Class in authorized denominations evidencing the same
aggregate Percentage Interest, as requested by the Holder surrendering the same.
No service charge will be made for any such registration of transfer or exchange
of Certificates, but the Trustee 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.

                  The Depositor, the Master Servicer, the Trustee, the
Securities Administrator, the Servicer and any agent of the Depositor, the
Master Servicer, the Trustee, the Securities Administrator or the Servicer 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
Trustee, the Securities Administrator, the Servicer nor any such agent shall be
affected by notice to the contrary.

                  The obligations created by the Agreement and the Trust Fund
created thereby shall terminate upon payment to the Certificateholders of all
amounts held by the Trustee and required to be paid to them pursuant to the
Agreement following the earlier of (i) the final payment or other liquidation
(or any advance with respect thereto) of the last Mortgage Loan remaining in
REMIC I and (ii) the purchase by the party designated in the Agreement at a
price determined as provided in the Agreement from REMIC I of all the Mortgage
Loans and all property acquired in respect of such Mortgage Loans. The Agreement
permits, but does not require, the party designated in the Agreement to purchase
from REMIC I all the Mortgage Loans and all property acquired in respect of any
Mortgage Loan at a price determined as provided in the Agreement. The exercise
of such right will effect early retirement of the Certificates; however, such
right to purchase is subject to the

                                      A-5-5

aggregate Stated Principal Balance of the Mortgage Loans at the time of purchase
being less than 10% of the aggregate principal balance of the Mortgage Loans as
of the Cut-off Date.

                  The recitals contained herein shall be taken as statements of
the Depositor and the Trustee assumes no responsibility for their correctness.

                  Unless the certificate of authentication hereon has been
executed by the Trustee, by manual signature, this Certificate shall not be
entitled to any benefit under the Agreement or be valid for any purpose.

                  IN WITNESS WHEREOF, the Trustee has caused this Certificate to
be duly executed.

Trustee of the pendency of such distribution and only upon presentation and
surrender of this Certificate at the office or agency appointed by the Trustee
for that purpose as provided in the Agreement.

                  This Certificate is one of a duly authorized issue of
Certificates designated as Asset Backed Pass-Through Certificates of the Series
specified on the face hereof (herein called the "Certificates") and representing
a Percentage Interest in the Class of Certificates specified on the face hereof
equal to the denomination specified on the face hereof divided by the aggregate
Certificate Principal Balance of the Class of Certificates specified on the face
hereof.

                  The Certificates are limited in right of payment 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 Collection Account and the Distribution Account
may be made from time to time for purposes other than distributions to
Certificateholders, such purposes including reimbursement of advances made, or
certain expenses incurred, with respect to the Mortgage Loans.

                  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 Trustee, the Securities
Administrator, the Servicer and the rights of the Certificateholders under the
Agreement at any time by the Depositor, the Master Servicer, the Trustee, the
Securities Administrator and the Servicer with the consent of the Holders of
Certificates entitled to at least 66% of the Voting Rights. 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, without the
consent of the Holders of any of the Certificates.

                  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 or agencies appointed by the Trustee as provided in
the Agreement, duly endorsed by, or accompanied by an assignment in the form
below or other written instrument of transfer in form satisfactory to the
Trustee duly executed by, the Holder hereof or such Holders attorney duly
authorized in writing, and thereupon one or more new Certificates of the same
Class in authorized denominations evidencing the same aggregate Percentage
Interest will be issued to the designated transferee or transferees.

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

                  No transfer of this Certificate shall be made unless the
transfer is made pursuant to an effective registration statement under the
Securities Act of 1933, as amended (the "1933 Act"), and an effective
registration or qualification under applicable state securities laws, or is made
in a transaction that does not require such registration or qualification. In
the event that such a transfer of this Certificate is to be made without
registration or qualification, the Trustee shall require receipt of (i) if such
transfer is purportedly being made in reliance upon Rule 144A under the 1933
Act, written certifications from the Holder of the Certificate desiring to
effect the transfer, and from such Holder's prospective transferee,
substantially in the forms attached to the Agreement as Exhibit B-1, and (ii) in
all other cases, an Opinion of Counsel satisfactory to it that such transfer may
be made without such registration or qualification (which Opinion of Counsel
shall not be an expense of the Trust Fund or of the Depositor, the Trustee, the
Master Servicer or the Securities Administrator in their respective capacities
as such), together with copies of the written certification(s) of the Holder of
the Certificate desiring to effect the transfer and/or such Holder's prospective
transferee upon which such Opinion of Counsel is based. Neither the Depositor
nor the Trustee is obligated to register or qualify the Class of Certificates
specified on the face hereof under the 1933 Act or any other securities law or
to take any action not otherwise required under the Agreement to permit the
transfer of such Certificates without registration or qualification. Any Holder
desiring to effect a transfer of this Certificate shall be required to indemnify
the Trustee, the Depositor, the Master Servicer and the Securities Administrator
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 Certificate to a Plan subject to ERISA or
Section 4975 of the Code, any Person acting, directly or indirectly, on behalf
of any such Plan or any Person using "Plan Assets" to acquire this Certificate
shall be made except in accordance with Section 6.02 of the Agreement.

                  Prior to registration of any transfer, sale or other
disposition of this Certificate, the proposed transferee shall provide to the
Trustee (i) an affidavit to the effect that such transferee is any Person other
than a Disqualified Organization or the agent (including a broker, nominee or
middleman) of a Disqualified Organization, and (ii) a certificate that
acknowledges that (A) the Class R Certificates have been designated as
representing the beneficial ownership of the residual interests in each of REMIC
I, REMIC II and REMIC III, (B) it will include in its income a PRO RATA share of
the net income of the Trust Fund and that such income may be an "excess
inclusion," as defined in the Code, that, with certain exceptions, cannot be
offset by other losses or benefits from any tax exemption, and (C) it expects to
have the financial means to satisfy all of its tax obligations including those
relating to holding the Class R Certificates. Notwithstanding the registration
in the Certificate Register of any transfer, sale or other disposition of this
Certificate to a Disqualified Organization or an agent (including a broker,
nominee or middleman) of a Disqualified Organization, such registration shall be
deemed to be of no legal force or effect whatsoever and such Person shall not be
deemed to be a Certificateholder for any purpose, including, but not limited to,
the receipt of distributions in respect of this Certificate.

                  The Holder of this Certificate, by its acceptance hereof,
shall be deemed to have consented to the provisions of Section 6.02 of the
Agreement and to any amendment of the Agreement deemed necessary by counsel of
the Depositor to ensure that the transfer of this Certificate to any Person
other than a Permitted Transferee or any other Person will not cause any portion
of the Trust Fund to cease to qualify as a REMIC or cause the imposition of a
tax upon any REMIC.

                  No service charge will be made for any such registration of
transfer or exchange of Certificates, but the Trustee 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.

                  The Depositor, the Master Servicer, the Trustee, the
Securities Administrator, the Servicer and any agent of the Depositor, the
Master Servicer, the Trustee, the Securities Administrator or the Servicer 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
Trustee, the Securities Administrator, the Servicer nor any such agent shall be
affected by notice to the contrary.

                  The obligations created by the Agreement and the Trust Fund
created thereby shall terminate upon payment to the Certificateholders of all
amounts held by the Trustee and required to be paid to them pursuant to the
Agreement following the earlier of (i) the final payment or other liquidation
(or any advance with respect thereto) of the last Mortgage Loan remaining in
REMIC I and (ii) the purchase by the party designated in the Agreement at a
price determined as provided in the Agreement from REMIC I of all the Mortgage
Loans and all property acquired in respect of such Mortgage Loans. The Agreement
permits, but does not require, the party designated in the

                                      A-6-6

<PAGE>

Agreement to purchase from REMIC I all the Mortgage Loans and all property
acquired in respect of any Mortgage Loan at a price determined as provided in
the Agreement. 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 Loans at the time of purchase being less than
10% of the aggregate principal balance of the Mortgage Loans as of the Cut-off
Date.

                  The recitals contained herein shall be taken as statements of
the Depositor and the Trustee does not assume responsibility for their
correctness.

                  Unless the certificate of authentication hereon has been
executed by the Trustee, by manual signature, this Certificate shall not be
entitled to any benefit under the Agreement or be valid for any purpose.

Ladies and Gentlemen:

                  In connection with the transfer by ______________________ (the
"Transferor") to ___________________ (the "Transferee") of the captioned
mortgage pass-through certificates (the "Certificates"), the Transferor hereby
certifies as follows:

                  Neither the Transferor nor anyone acting on its behalf has (a)
offered, pledged, sold, disposed of or otherwise transferred any Certificate,
any interest in any Certificate or any other similar security to any person in
any manner, (b) has solicited any offer to buy or to accept a pledge,
disposition or other transfer of any Certificate, any interest in any
Certificate or any other similar security from any person in any manner, (c) has
otherwise approached or negotiated with respect to any Certificate, any interest
in any Certificate or any other similar security with any person in any manner,
(d) has made any general solicitation by means of general advertising or in any
other manner, (e) has taken any other action, that (in the case of each of
subclauses (a) through (e) above) would constitute a distribution of the
Certificates under the Securities Act of 1933, as amended (the "1933 Act"), or
would render the disposition of any Certificate a violation of Section 5 of the
1933 Act or any state securities law or would require registration or
qualification pursuant thereto. The Transferor will not act, nor has it
authorized or will it authorize any person to act, in any manner set forth in
the foregoing sentence with respect to any Certificate. The Transferor will not
sell or otherwise transfer any of the Certificates, except in compliance with
the provisions of that certain Pooling and Servicing Agreement, dated as of May

                       -------------------------------------------------------

Ladies and Gentlemen:

                  In connection with the purchase from ________________________
(the "Transferor") on the date hereof of the captioned trust certificates (the
"Certificates"), (the "Transferee") hereby certifies as follows:

                  1. The Transferee is a "qualified institutional buyer" as that
             term is defined in Rule 144A ("Rule 144A") under the Securities Act
             of 1933 (the "1933 Act") and has completed either of the forms of
             certification to that effect attached hereto as Annex 1 or Annex 2.
             The Transferee is aware that the sale to it is being made in
             reliance on Rule 144A. The Transferee is acquiring the Certificates
             for its own account or for the account of a qualified institutional
             buyer, and understands that such Certificate may be resold, pledged
             or transferred only (i) to a person reasonably believed to be a
             qualified institutional buyer that purchases for its own account or
             for the account of a qualified institutional buyer to whom notice
             is given that the resale, pledge or transfer is being made in
             reliance on Rule 144A, or (ii) pursuant to another exemption from
             registration under the 1933 Act.

                  2. The Transferee has been furnished with all information
             regarding (a) the Certificates and distributions thereon, (b) the
             nature, performance and servicing of the Mortgage Loans, (c) the
             Pooling and Servicing Agreement referred to below, and (d) any
             credit enhancement mechanism associated with the Certificates, that
             it has requested.

                  3. The Transferee: (a) is not an employee benefit or other
             plan subject to the prohibited transaction provisions of the
             Employee Retirement Income Security Act of 1974, as amended
             ("ERISA), or Section 4975 of the Internal Revenue Code of 1986, as
             amended ("Plan"), or any other person (including an investment
             manager, a named fiduciary or a trustee of any Plan) acting,
             directly or indirectly, on behalf of or purchasing any Certificate
             with "plan assets" of any Plan within the meaning of the Department
             of Labor ("DOL") regulation at 29 C.F.R. ss.2510.3-101 or (b) has
             provided the Trustee, the Depositor and the Servicer with an
             opinion of counsel acceptable to and in form and

<PAGE>

             substance satisfactory to such parties to the effect that the
             purchase of Certificates is permissible under applicable law, will
             not constitute or result in any non-exempt prohibited transaction
             under ERISA or Section 4975 of the Code and will not subject the
             Trustee, the Depositor or the Servicer to any obligation or
             liability (including obligations or liabilities under ERISA or
             Section 4975 of the Code) in addition to those undertaken in the
             Pooling and Servicing Agreement.

             In addition, the Transferee hereby certifies, represents and
warrants to, and covenants with, the Depositor, the Trustee and the Servicer
that the Transferee will not transfer such Certificates to any Plan or person
unless such Plan or person meets the requirements set forth in either 3(a) or
(b) above.

             All capitalized terms used but not otherwise defined herein have
the respective meanings assigned thereto in the Pooling and Servicing Agreement,

Transferee used the cost of such securities to the Transferee and did not

<PAGE>

                  6. If the answer to the foregoing question is "no", the
Transferee agrees that, in connection with any purchase of securities sold to
the Transferee for the account of a third party (including any separate account)
in reliance on Rule 144A, the Transferee will only purchase for the account of a
third party that at the time is a "qualified institutional buyer" within the
meaning of Rule 144A. In addition, the Transferee agrees that the Transferee
will not purchase securities for a third party unless the Transferee has
obtained a current representation letter from such third party or taken other
appropriate steps contemplated by Rule 144A to conclude that such third party
independently meets the definition of "qualified institutional buyer" set forth
in Rule 144A.

                  7. 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

parties updated annual financial statements promptly after they become

certifies as follows:

                  1. The Transferee understands that (a) the Certificates have
             not been and will not be registered or qualified under the

                  2. The Transferee is acquiring the Certificates for its own
             account for investment only and not with a view to or for sale in
             connection with any distribution thereof in any manner that would

             institutional investor having such knowledge and experience in
             financial and business matters, and, in particular, in such matters

             investment and (c) an "accredited investor" within the meaning of

             opportunity to review (a) a copy of the Pooling and Servicing
             Agreement and (b) such other information concerning the
             Certificates, the Mortgage Loans and the Depositor as has been
             requested by the Transferee from the Depositor or the Transferor
             and is relevant to the Transferee's decision to purchase the
             Certificates. The Transferee has had any questions arising from

                                      B-2-2

             Certificate or any other similar security to any person in any
             manner, (b) solicit any offer to buy or to accept a pledge,
             disposition of other transfer of any Certificate, any interest in
             any Certificate or any other similar security from any person in
             any manner, (c) otherwise approach or negotiate with respect to any
             Certificate, any interest in any Certificate or any other similar
             security with any person in any manner, (d) make any general
             solicitation by means of general advertising or in any other manner
             or (e) take any other action, that (as to any of (a) through (e)
             above) would constitute a distribution of any Certificate under the
             Act, that would render the disposition of any Certificate a
             violation of Section 5 of the 1933 Act or any state securities law,
             or that would require registration or qualification pursuant
             thereto. The Transferee will not sell or otherwise transfer any of
             the Certificates, except in compliance with the provisions of the
             Pooling and Servicing Agreement.

                  6. The Transferee: (a) is not an employee benefit or other
             plan subject to the prohibited transaction provisions of the

                        TRANSFER AFFIDAVIT AND AGREEMENT

STATE OF NEW YORK               )
                                ss.:
COUNTY OF NEW YORK              )

             ___________________________ being duly sworn, deposes, represents
and warrants as follows:

             1.   I am a _____________________ of
                  _______________________________ (the "Owner") a corporation
                  duly organized and existing under the laws of
                  _________________________, the record owner of ACE Securities
                  Corp. Home Equity Loan Trust, Series 2003-FM1, Asset Backed
                  Pass-Through Certificates, Series 2003-FM1, Class R
                  Certificates (the "Class R Certificates"), on behalf of whom I
                  make this affidavit and agreement. Capitalized terms used but
                  not defined herein have the respective meanings assigned
                  thereto in the Pooling and Servicing Agreement pursuant to
                  which the Class R Certificates were issued.

             2.   The Owner (i) is and will be a "Permitted Transferee" as of
                  ____________________. ____ and (ii) is acquiring the Class R
                  Certificates for its own account or for the account of another
                  Owner from which it has received an affidavit in substantially
                  the same form as this affidavit. A "Permitted Transferee" is
                  any person other than a "disqualified organization" or a
                  possession of the United States. For this purpose, a
                  "disqualified organization" means the United States, any state
                  or political subdivision thereof, any agency or
                  instrumentality of any of the foregoing (other than an
                  instrumentality all of the activities of which are subject to
                  tax and, except for the Federal Home Loan Mortgage
                  Corporation, a majority of whose board of directors is not
                  selected by any such governmental entity) or any foreign
                  government, international organization or any agency or
                  instrumentality of such foreign government or organization,
                  any real electric or telephone cooperative, or any
                  organization (other than certain farmers' cooperatives) that
                  is generally exempt from federal income tax unless such
                  organization is subject to the tax on unrelated business
                  taxable income.

             3.   The Owner is aware (i) of the tax that would be imposed on
                  transfers of the Class R Certificates to disqualified
                  organizations under the Internal Revenue Code of 1986 that
                  applies to all transfers of the Class R 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 non-Permitted
                  Transferee, on the agent; (iii) that the person otherwise
                  liable for the tax shall be relieved of liability

<PAGE>

                  for the tax if the transferee furnishes to such person an
                  affidavit that the transferee is a Permitted Transferee and,
                  at the time of transfer, such person does not have actual
                  knowledge that the affidavit is false; and (iv) that each of
                  the Class R Certificates may be a "noneconomic residual
                  interest" within the meaning of proposed Treasury regulations
                  promulgated under the Code 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
                  impede the assessment or collection of tax.

             4.   The Owner is aware of the tax imposed on a "pass-through
                  entity" holding the Class R 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.   The Owner is aware that the Trustee will not register the
                  transfer of any Class R 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 Owner 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.

             6.   The Owner 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 Certificates will only be owned, directly or
                  indirectly, by an Owner that is a Permitted Transferee.

             7.   The Owner's taxpayer identification number is
                  ________________.

             8.   The Owner has reviewed the restrictions set forth on the face
                  of the Class R Certificates and the provisions of Section
                  6.02(d) of the Pooling and Servicing Agreement under which the
                  Class R Certificates were issued (in particular, clauses
                  (iii)(A) and (iii)(B) of Section 6.02(d) which authorize the
                  Trustee to deliver payments to a person other than the Owner
                  and negotiate a mandatory sale by the Trustee in the event
                  that the Owner holds such Certificate in violation of Section
                  6.02(d)); and that the Owner expressly agrees to be bound by
                  and to comply with such restrictions and provisions.

             9.   The Owner is not acquiring and will not transfer the Class R
                  Certificates in order to impede the assessment or collection
                  of any tax.

             10.  The Owner anticipates that it will, so long as it holds the
                  Class R Certificates, have sufficient assets to pay any taxes
                  owed by the holder of such Class R Certificates, and hereby
                  represents to and for the benefit of the person from whom it
                  acquired the Class R Certificates that the Owner intends to
                  pay taxes associated with holding such

                                      B-3-2

<PAGE>

                  Class R Certificates as they become due, fully understanding
                  that it may incur tax liabilities in excess of any cash flows
                  generated by the Class R Certificates.

             11.  The Owner has no present knowledge that it may become
                  insolvent or subject to a bankruptcy proceeding for so long as
                  it holds the Class R Certificates.

             12.  The Owner 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.

             13.  The Owner is not acquiring the Class R Certificates with the
                  intent to transfer the Class R Certificates to any person or
                  entity that will not have sufficient assets to pay any taxes
                  owed by the holder of such Class R Certificates, or that may
                  become insolvent or subject to a bankruptcy proceeding, for so
                  long as the Class R Certificates remain outstanding.

             14.  The Owner will, in connection with any transfer that it makes
                  of the Class R Certificates, obtain from its transferee the
                  representations required by Section 6.02(d) of the Pooling and
                  Servicing Agreement under which the Class R Certificate were
                  issued and will not consummate any such transfer if it knows,
                  or knows facts that should lead it to believe, that any such
                  representations are false.

             15.  The Owner will, in connection with any transfer that it makes
                  of the Class R Certificates, deliver to the Trustee an
                  affidavit, which represents and warrants that it is not
                  transferring the Class R Certificates 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 the Class R
                  Certificates; (ii) may become insolvent or subject to a
                  bankruptcy proceeding for so long as the Class R Certificates
                  remains outstanding; and (iii) is not a "Permitted
                  Transferee".

             16.  The Owner is a citizen or resident of the United States, a
                  corporation, partnership or other entity created or organized
                  in, or under the laws of, the United States or any political
                  subdivision thereof, or an estate or trust whose income from
                  sources without the United States may be included in gross
                  income for United States federal income tax purposes
                  regardless of its connection with the conduct of a trade or
                  business within the United States.

             17.  The Owner of the Class R Certificate, hereby agrees that in
                  the event that the Trust Fund created by the Pooling and
                  Servicing Agreement is terminated pursuant to Section 10.01
                  thereof, the undersigned shall assign and transfer to the
                  Holders of the Class CE and the Class P Certificates any
                  amounts in excess of par received in connection with such
                  termination. Accordingly, in the event of such termination,
                  the Trustee is hereby authorized to withhold any such amounts
                  in excess of par and to pay such amounts directly to the
                  Holders of the Class CE and the Class P Certificates. This
                  agreement shall bind and be enforceable against any successor,
                  transferee or assigned of the undersigned in the Class R
                  Certificate. In connection

                                      B-3-3

<PAGE>

                  with any transfer of the Class R Certificate, the Owner shall
                  obtain an agreement substantially similar to this clause from
                  any subsequent owner.

COUNTY OF NEW YORK              )

                  _________________________, being duly sworn, deposes,
represents and warrants as follows:

                  1. I am a ____________________ of _________________________
(the "Owner"), a corporation duly organized and existing under the laws of
_____________, on behalf of whole I make this affidavit.

                  2. The Owner is not transferring the Class R Certificates (the
"Residual Certificates") to impede the assessment or collection of any tax.

                  3. The Owner has no actual knowledge that the Person that is
the proposed transferee (the "Purchaser") of the Residual Certificates: (i) has
insufficient assets to pay any taxes owed by such proposed transferee as holder
of the Residual Certificates; (ii) may become insolvent or subject to a
bankruptcy proceeding for so long as the Residual Certificates remain
outstanding and (iii) is not a Permitted Transferee.

                  4. The Owner understands that the Purchaser has delivered to
the Trustee or a transfer affidavit and agreement in the form attached to the
Pooling and Servicing Agreement as Exhibit B-2. The Owner does not know or
believe that any representation contained therein is false.

                  5. At the time of transfer, the Owner has conducted a
reasonable investigation of the financial condition of the Purchaser as
contemplated by Treasury Regulations Section 1.860E-1(c)(4)(i) and, as a result
of that investigation, the Owner has determined that the Purchaser has
historically paid its debts as they became due and has found no significant
evidence to indicate that the Purchaser will not continue to pay its debts as
they become due in the future. The Owner understands that the transfer of a
Residual Certificate may not be respected for United States income tax purposes
(and the Owner may continue to be liable for United States income taxes
associated therewith) unless the Owner has conducted such an investigation.

                  6. Capitalized terms not otherwise defined herein shall have
the meanings ascribed to them in the Pooling and Servicing Agreement.

Re:          ACE Securities Corp. Home Equity Loan Trust, Series 2003-FM1
             Asset Backed Pass-Through Certificates

             I, [identify the certifying individual], certify to ACE Securities
Corp. (the "Depositor"), JPMorgan Chase Bank (the "Trustee") and Wells Fargo
Bank Minnesota, National Association (the "Master Servicer"), and their
respective officers, directors and affiliates, and with the knowledge and intent
that they will rely upon this certification, that:

             1. Based on my knowledge, the information in the Annual Statement
of Compliance, the Annual Independent Public Accountant's Servicing Report and
all servicing reports, officer's certificates and other information relating to
the servicing of the Mortgage Loans submitted to the Master Servicer taken as a
whole, does not contain any untrue statement of a material fact or omit to state

<PAGE>
such Holders in person or by an agent or proxy duly appointed in writing by such
Holders or (B) the record of Holders of Securities voting in favor thereof,
either in person or by proxies duly appointed in writing, at any meeting of
Holders of Securities duly called and held in accordance with the provisions of
Article IX. Such action shall become effective when such instrument or
instruments or record is delivered to the Trustee and, where it is hereby
expressly required, to the Company. The Trustee shall promptly deliver to the
Company copies of all such instruments and records delivered to the Trustee.
Such instrument or instruments and records (and the action embodied therein and
evidenced thereby) are herein sometimes referred to as the "Act" of the Holders
of Securities signing such instrument or instruments and so voting at such
meeting. Proof of execution of any such instrument or of a writing appointing
any such agent or proxy, or of the holding by any Person of a Security, shall be
sufficient for any purpose of this Indenture and (subject to Section 6.1)
conclusive in favor of the Trustee and the Company if made in the manner
provided in this Section. The record of any meeting of Holders of Securities
shall be proved in the manner provided in Section 9.6.

         (2) The fact and date of the execution by any Person of any such
instrument or writing may be proved by the affidavit of a witness of such
execution or by a certificate of a notary public or other officer authorized by
law to take acknowledgments of deeds, certifying that the individual signing
such instrument or writing acknowledged to him the execution thereof. Where such
execution is by a signer acting in a capacity other than his individual
capacity, such certificate or affidavit shall also constitute sufficient proof
of his authority.

         (3) The principal amount and serial number of any Security held by any
Person, and the date of his holding the same, shall be proved by the Security
Register.

         (4) The fact and date of execution of any such instrument or writing
and the authority of the Person executing the same may also be proved in any
other manner which the Trustee deems sufficient; and the Trustee may in any
instance require further proof with respect to any of the matters referred to in
this Section 1.4.

         (5) The Company may set any day as the record date for the purpose of
determining the Holders entitled to give or take any request, demand,
authorization, direction, notice, consent, waiver or other action, or to vote on
any action, authorized or permitted by this Indenture to be given or taken by
Holders. Promptly and in any case not later than ten days after setting a record
date, the Company shall notify the Trustee and the Holders of such record date.
If not set by the Company prior to the first solicitation of a Holder made by
any Person in respect of any such action, or, in the case of any such vote,
prior to such vote, the record date for any such action or vote shall be the
30th day (or, if later, the date of the most recent list of Holders required to
be provided pursuant to Section 15.1) prior to such first solicitation or vote,
as the case may be. With regard to any record date, the Holders on such date (or
their duly appointed agents or proxies), and only such Persons, shall be
entitled to give or take, or vote on, the relevant action, whether or not such
Holders remain Holders after such record date. Notwithstanding the foregoing,
the Company shall not set a record date for, and the provisions of this
paragraph shall not apply with respect to, any notice, declaration or direction
referred to in the next paragraph.

                                                                            -12-
<PAGE>
         Upon receipt by the Trustee from any Holder of (i) any notice of
default or breach referred to in Section 5.1(4), if such default or breach has
occurred and is continuing and the Trustee shall not have given such a notice to
the Company, (ii) any declaration of acceleration referred to in Section 5.2, if
an Event of Default has occurred and is continuing and the Trustee shall not
have given such a declaration to the Company, or (iii) any direction referred to
in Section 5.12, if the Trustee shall not have taken the action specified in
such direction, then, with respect to clauses (ii) and (iii), a record date
shall automatically and without any action by the Company or the Trustee be set
for determining the Holders entitled to join in such declaration or direction,
which record date shall be the close of business on the tenth day (or, if such
day is not a Business Day, the first Business Day thereafter) following the day
on which the Trustee receives such declaration or direction, and, with respect
to clause (i), the Trustee may set any day as a record date for the purpose of
determining the Holders entitled to join in such notice of default. Promptly
after such receipt by the Trustee of any such declaration or direction referred
to in clause (ii) or (iii), and promptly after setting any record date with
respect to clause (i), and as soon as practicable thereafter, the Trustee shall
notify the Company and the Holders of any such record date so fixed. The Holders
on such record date (or their duly appointed agents or proxies), and only such
Persons, shall be entitled to join in such notice, declaration or direction,
whether or not such Holders remain Holders after such record date; provided
that, unless such notice, declaration or direction shall have become effective
by virtue of Holders of the requisite principal amount of Securities on such
record date (or their duly appointed agents or proxies) having joined therein on
or prior to the 90th day after such record date, such notice, declaration or
direction shall automatically and without any action by any Person be canceled
and of no further effect. Nothing in this paragraph shall be construed to
prevent a Holder (or a duly appointed agent or proxy thereof) from giving,
before or after the expiration of such 90-day period, a notice, declaration or
direction contrary to or different from, or, after the expiration of such
period, identical to, the notice, declaration or direction to which such record
date relates, in which event a new record date in respect thereof shall be set
pursuant to this paragraph. In addition, nothing in this paragraph shall be
construed to render ineffective any notice, declaration or direction of the type
referred to in this paragraph given at any time to the Trustee and the Company
by Holders (or their duly appointed agents or proxies) of the requisite
principal amount of Securities on the date such notice, declaration or direction
is so given.

         (6) Except as provided in Sections 5.12 and 5.13, any request, demand,
authorization, direction, notice, consent, election, waiver or other Act of the
Holder of any Security shall bind every future Holder of the same Security and
the Holder of every Security issued upon the registration of transfer thereof or
in exchange therefor or in lieu thereof in respect of anything done, omitted or
suffered to be done by the Trustee or the Company in reliance thereon, whether
or not notation of such action is made upon such Security.

         (7) The provisions of this Section 1.4 are subject to the provisions of
Section 9.5.

                                                                            -13-

         Any request, demand, authorization, direction, notice, consent,
election, waiver or other Act of Holders of Securities or other document
provided or permitted by this Indenture to be made upon, given or furnished to,
or filed with,

         (1) the Trustee by any Holder of Securities or by the Company shall be
sufficient for every purpose hereunder if made, given, furnished or filed in
writing to or with a Responsible Officer of the Trustee and received at its
Corporate Trust Office, Attention: Corporate Trust Administration (Corixa
Corporation, 4.25% Convertible Subordinated Notes due July 1, 2008).

sufficient for every purpose hereunder (unless otherwise herein expressly
provided) if in writing, mailed, first-class postage prepaid, or telecopied and

overnight courier, addressed to the Company at 1124 Columbia St., Suite 200,

SECTION 1.6       Notice to Holders of Securities; Waiver.

         Except as otherwise expressly provided herein, where this Indenture
provides for notice to Holders of Securities of any event, such notice shall be
sufficiently given to Holders if in writing and mailed, first-class postage
prepaid or delivered by an overnight delivery service, to each Holder of a
Security affected by such event, at the address of such Holder as it appears in
the Security Register, not earlier than the earliest date and not later than the
latest date prescribed for the giving of such notice.

         Neither the failure to mail such notice, nor any defect in any notice
so mailed, to any particular Holder of a Security shall affect the sufficiency
of such notice with respect to other Holders of Securities. In case by reason of
the suspension of regular mail service or by reason of any other cause it shall
be impracticable to give such notice by mail, then such notification to Holders
of Securities as shall be made with the approval of the Trustee, which approval
shall not be unreasonably withheld, shall constitute a sufficient notification
to such Holders for every purpose hereunder.

         Such notice shall be deemed to have been given when such notice is
mailed.

         Where this Indenture provides for notice in any manner, such notice may
be waived in writing by the Person entitled to receive such notice, either
before or after the event, and such waiver shall be the equivalent of such
notice. Waivers of notice by Holders of Securities shall be filed with the
Trustee, but such filing shall not be a condition precedent to the validity of
any action taken in reliance upon such waiver.

                                                                            -14-

Redemption Price or Repurchase Price (whether the same is payable in cash or in
shares of Common Stock in the case of the Repurchase Price) with respect to, or
delivery for conversion of, such Security need not be made at such Place of
Payment or Place of Conversion, as the case may be, on or by such day, but may

Place of Conversion, as the case may be, with the same force and effect as if

      CORIXA CORPORATION, a corporation duly organized and existing under the
laws of the State of Delaware (herein called the "Company", which term includes
any successor Person under the Indenture referred to on the reverse hereof), for
value received, hereby promises to pay to _________________, or registered
assigns, the principal sum of ________ United States Dollars (U.S.$______ )
(which principal amount may from time to time be increased or decreased to such
other principal amounts (which, taken together with the principal amounts of all
other Outstanding Securities, shall not exceed $[__________]) by adjustments
made on the records of the Trustee hereinafter referred to in accordance with
the Indenture) on July 1, 2008 and to pay interest thereon, from June 13, 2003,
or from the most recent Interest Payment Date (as defined below) to which
interest has been paid or duly provided for, semi-annually in arrears on January
1 and July 1 in each year (each, an "Interest Payment Date"), commencing January
1, 2004, at the rate of 4.25% per annum, until the principal hereof is due, and
at the rate of 4.25% per annum on any overdue principal and premium, if any,
and, to the extent permitted by law, on any overdue interest. The interest so
payable, and punctually paid or duly provided for, on any Interest Payment Date
will, as provided in the Indenture, be paid to the Person in whose name this
Security (or one or more Predecessor Securities) is registered at the close of
business on the Regular Record Date for such interest, which shall be the
December 15 or June 15 (whether or not a Business Day), as the case may be, next
preceding such Interest Payment Date. Except as otherwise provided in the
Indenture, any such interest not so punctually paid or duly provided for will
forthwith cease to be payable to the Holder on such Regular Record Date and may
either be paid to the Person in whose name this Security (or one or more
Predecessor Securities) is registered at the close of business on a Special
Record Date for the payment of such Defaulted Interest to be fixed by the
Company, notice whereof shall be given to Holders of Securities not less than 10
days prior to the Special Record Date, or be paid at any time in any other
lawful manner not inconsistent with the requirements of any automated quotation
system or securities exchange on which the Securities may be quoted or listed,
and upon such notice as may be required by such exchange, all as more fully
provided in the Indenture. Payments of principal shall be made upon the
surrender of this Security at the option of the Holder at the Corporate Trust
Office of the Trustee, or at such other office or agency of the Company as may
be designated by it for such purpose in the Borough of Manhattan, The City of
New York, in such lawful monies of the United States of America as at the time
of payment shall be legal tender for the payment of public and private debts, or
at such other offices or agencies as the Company may designate, by United States
Dollar check drawn on, or wire transfer to, a United States Dollar account (such

the Security Registrar setting forth wire instructions not later than the
relevant Record Date, by transfer to a United States Dollar account (such a
transfer to be made only to a Holder of an aggregate principal amount of
Securities in excess of U.S.$2,000,000 and only if such Holder shall have
furnished wire instructions in writing to the Trustee no later than 15 days
prior to the relevant payment date).

      Except as specifically provided herein and in the Indenture, the Company
shall not be required to make any payment with respect to any tax, assessment or
other governmental charge imposed by any government or any political subdivision
or taxing authority thereof or therein.

      Reference is hereby made to the further provisions of this Security set
forth on the reverse hereof, which further provisions shall for all purposes
have the same effect as if set forth at this place.

as Trustee

By:  _______________________________________
         Authorized Signatory

                                                                            -22-

                                [FORM OF REVERSE]

      This Security is one of a duly authorized issue of securities of the
Company designated as its "4.25% Convertible Subordinated Notes due July 1,
2008" (herein called the "Securities"), limited in aggregate principal amount to
U.S. $[__________], issued and to be issued under an Indenture, dated as of June
13, 2003 (herein called the "Indenture"), between the Company and Wells Fargo
Bank, National Association, as Trustee (herein called the "Trustee," which term
includes any successor trustee under the Indenture), to which Indenture and all
indentures supplemental thereto reference is hereby made for a statement of the
respective rights, limitations of rights, duties and immunities thereunder of
the Company, the Trustee, the holders of Senior Debt and the Holders of the
Securities and of the terms upon which the Securities are, and are to be,
authenticated and delivered. As provided in the Indenture and subject to certain
limitations therein set forth, Securities are exchangeable for a like aggregate
principal amount of Securities of any authorized denominations as requested by
the Holder surrendering the same upon surrender of the Security or Securities to
be exchanged, at the Corporate Trust Office of the Trustee. The Trustee upon
such surrender by the Holder will issue the new Securities in the requested
denominations.

      No sinking fund is provided for the Securities.

      The Company may not redeem the Securities prior to July 5, 2005. The
Securities are subject to redemption at the option of the Company at any time on
or after July 5, 2005, in whole or in part, at a Redemption Price equal to 100%
of the principal amount (provided, however, that if the Redemption Date is
before July 1, 2007, the Company may redeem the Securities only if the Closing
Price Per Share of the Company's Common Stock exceeds 140% of the Conversion
Price for at least 20 Trading Days in any consecutive 30 day trading period upon
not less than 30 nor more than 60 days' notice to the Holders prior to the
Redemption Date) at a Redemption Price equal to 100% of the principal amount,
together with accrued interest to, but excluding, the Redemption Date; provided,
however, that interest installments on Securities whose Stated Maturity is on or
prior to such Redemption Date will be payable to the Holders of such Securities,
or one or more Predecessor Securities, of record at the close of business on the
relevant Record Dates referred to on the face hereof, all as provided in the
Indenture.

      In the event of a redemption of the Securities, the Company will not be
required (a) to register the transfer or exchange of Securities for a period of
15 days immediately preceding the date notice is given identifying the serial
numbers of the Securities called for such redemption or (b) to register the
transfer or exchange of any Security, or portion thereof, called for redemption.

      In any case where the due date for the payment of the principal of,
premium, if any, interest, or Liquidated Damages on any Security or the last day
on which a Holder of a Security has a right to convert his Security shall be, at
any Place of Payment or Place of Conversion as the case may be, a day on which
banking institutions at such Place of Payment or Place of Conversion are
authorized or obligated by law or executive order to close, then payment of
principal, premium, if any, interest, or Liquidated Damages, or delivery for
conversion of such Security need not be made on or by such date at such place
but may be made on or by the next succeeding day at such place which is not a
day on which banking institutions are authorized or obligated by law or
executive order to close,

                                                                            -23-
<PAGE>
with the same force and effect as if made on the date for such payment or the
date fixed for redemption or repurchase, or by such last day for conversion, and
no interest shall accrue on the amount so payable for the period after such
date.

      Subject to and upon compliance with the provisions of the Indenture, the
Holder of this Security is entitled, at his option, at any time on or before the
close of business on the date of Maturity, or in case this Security or a portion
hereof is called for redemption or the Holder hereof has exercised his right to
require the Company to repurchase this Security or such portion hereof, then in
respect of this Security until the Business Day immediately preceding, but
(unless the Company defaults in making the payment due upon redemption or
repurchase, as the case may be) not after, the close of business on the Business
Day immediately preceding the Redemption Date or the Repurchase Date, as the
case may be, to convert this Security (or any portion of the principal amount
hereof that is an integral multiple of U.S.$1,000, provided that the unconverted
portion of such principal amount is U.S.$1,000 or any integral multiple of
U.S.$1,000 in excess thereof) into fully paid and nonassessable shares of Common
Stock of the Company at an initial Conversion Rate equal to the quotient
obtained by dividing 1000 by $9.175 for each U.S.$1,000 principal amount of
Securities (or at the current adjusted Conversion Rate if an adjustment has been
made as provided in the Indenture) by surrender of this Security, duly endorsed
or assigned to the Company or in blank and, in case such surrender shall be made
during the period from the close of business on any Regular Record Date next
preceding any Interest Payment Date to the opening of business on such
succeeding Interest Payment Date (except if this Security or portion thereof has
been called for redemption or if a Change in Control has occurred and an offer
to repurchase the Securities is pending), also accompanied by payment in New
York Clearing House or other funds acceptable to the Company of an amount equal
to the interest payable on such Interest Payment Date on the principal amount of
this Security then being converted, and also the conversion notice hereon duly
executed, to the Company at the Corporate Trust Office of the Trustee, or at
such other office or agency of the Company, subject to any laws or regulations
applicable thereto and subject to the right of the Company to terminate the
appointment of any Conversion Agent (as defined below) as may be designated by
it for such purpose in the Borough of Manhattan, The City of New York, or at
such other offices or agencies as the Company may designate (each a "Conversion
Agent"). The interest that is payable on such Interest Payment Date with respect
to any Security (or portion thereof, if applicable) that is surrendered for
conversion during the Record Date Period shall be paid to the Holder of such
Security as of such Regular Record Date in an amount equal to the interest that
would have been payable on such Security if such Security had been converted as
of the close of business on such Interest Payment Date. Subject to the
provisions of the preceding sentence and, in the case of a conversion after the
close of business on the Regular Record Date next preceding any Interest Payment
Date and on or before the close of business on such Interest Payment Date, to
the right of the Holder of this Security (or any Predecessor Security of record
as of such Regular Record Date) to receive the related installment of interest
to the extent and under the circumstances provided in the Indenture, no cash
payment or adjustment is to be made on conversion for interest accrued hereon
from the Interest Payment Date next preceding the day of conversion, or for
dividends on the Common Stock issued on conversion hereof. The Company shall
thereafter deliver to the Holder the fixed number of shares of Common Stock
(together with any cash adjustment, as provided in the Indenture) into which
this Security is convertible and such delivery will be deemed to satisfy the

                                                                            -24-
<PAGE>
Company's obligation to pay the principal amount of this Security. No fractions
of shares or scrip representing fractions of shares will be issued on
conversion, but instead of any fractional interest (calculated to the nearest
1/100th of a share) the Company shall pay a cash adjustment as provided in the
Indenture. The Conversion Rate is subject to adjustment as provided in the
Indenture. In addition, the Indenture provides that in case of certain
consolidations or mergers to which the Company is a party (other than a
consolidation or merger that does not result in any reclassification,
conversion, exchange or cancellation of the Common Stock) or the conveyance,
transfer, sale or lease of all or substantially all of the property and assets
of the Company, the Indenture shall be amended, without the consent of any
Holders of Securities, so that this Security, if then Outstanding, will be
convertible thereafter, during the period this Security shall be convertible as
specified above, only into the kind and amount of securities, cash and other
property receivable upon such consolidation, merger, conveyance, transfer, sale
or lease by a holder of the number of shares of Common Stock of the Company into
which this Security could have been converted immediately prior to such
consolidation, merger, conveyance, transfer, sale or lease (assuming such holder
of Common Stock is not a Constituent Person or an Affiliate of a Constituent
Person, failed to exercise any rights of election and received per share the
kind and amount received per share by a plurality of Non-electing Shares). No
adjustment in the Conversion Rate will be made until such adjustment would
require an increase or decrease of at least one percent of such rate, provided
that any adjustment that would otherwise be made will be carried forward and
taken into account in the computation of any subsequent adjustment.

      If this Security is a Registrable Security (as defined in the Indenture),
then the Holder of this Security (including any Person that has a beneficial
interest in this Security) and the Common Stock of the Company issuable upon
conversion hereof is entitled to the benefits of a Registration Rights
Agreement, dated as of June 13, 2003, executed by the Company (the "Registration
Rights Agreement"). Pursuant to the Registration Rights Agreement, the Company
has agreed for the benefit of the Holders from time to time of the Registrable
Securities that it will, at its expense, (a) within 90 days after the Issue Date
file a shelf registration statement (the "Shelf Registration Statement") with
the Commission with respect to resales of the Registrable Securities, (b) use
its reasonable efforts to cause such Shelf Registration Statement to be declared
effective by the Commission within 180 days after the Issue Date, provided,
however, that the Company may, upon written notice to all the Holders, postpone
having the Shelf Registration Statement declared effective for a reasonable
period not to exceed 90 days if the Company possesses material non-public
information, the disclosure of which would have a material adverse effect on the
Company and its subsidiaries taken as a whole, and (c) use its reasonable
efforts to maintain such Shelf Registration Statement effective under the
Securities Act of 1933, as amended, until the second annual anniversary of the
Issue Date or, if earlier, until there are no outstanding Registrable Securities
(the "Effectiveness Period"). The Company will be permitted to suspend the use
of the prospectus which is part of the Shelf Registration Statement during
certain periods of time as provided in the Registration Rights Agreement.

      If (i) on or prior to 90 days following the Issue Date, a Shelf
Registration Statement has not been filed with the Commission, or (ii) on or
prior to the 180th day following the Issue Date, such Shelf Registration
Statement is not declared effective (each, a "Registration Default"), additional

                                                                            -25-
<PAGE>
interest ("Liquidated Damages") will accrue on the Registrable Securities from
and including the day following such Registration Default to but excluding the
day on which such Registration Default has been cured. Liquidated Damages will
be paid semi-annually in arrears, with the first semi-annual payment due on the
first Interest Payment Date, as applicable, in respect of the Registrable
Securities following the date on which such Liquidated Damages begin to accrue,
and will accrue at a rate per annum equal to one-quarter of one percent (0.25%)
of the principal amount of the Registrable Securities to and including the 90th
day following such Registration Default and at a rate per annum equal to
one-half of one percent (0.50%) thereof from and after the 91st day following
such Registration Default. Pursuant to the Registration Rights Agreement, in the
event that the Shelf Registration Statement ceases to be effective (or the
Holders of Registrable Securities are otherwise prevented or restricted by the
Company from effecting sales pursuant thereto) (an "Effective Failure") during
the Effectiveness Period for more than 45 days, whether or not consecutive,
during any 90-day period or for more than 90 days, whether or not consecutive,
during any 365-day period, then the interest rate borne by the Registrable
Securities shall increase by an additional one-quarter of one percent (0.25%)
per annum from the 46th day of the applicable 90-day period or shall increase by
an additional one-half of one percent (0.50%) per annum from the 91st day of the
applicable 365-day period until the earlier of (A) such time as the Effective
Failure is cured or (B) the Effectiveness Period expires. Liquidated Damages
will accrue (1) with respect to a Restricted Security at the rates set forth
above, as applicable, on the principal amount of the Restricted Securities and
(2) in respect of the Common Sock issued upon conversion of the Restricted
Securities, at the rates set forth above, as applicable, applied to the
Conversion Price at that time. In no event shall the Company be required to pay
Liquidated Damages in excess of the applicable maximum amount of one-half of one
percent (0.50%) set forth above regardless of whether one or multiple
Registration Defaults exist.

      Whenever in this Security there is a reference, in any context, to the
payment of the principal of, premium, if any, or interest on, or in respect of,
any Security, such mention shall be deemed to include mention of the payment of
Liquidated Damages payable as described in the preceding paragraph to the extent
that, in such context, Liquidated Damages are, were or would be payable in
respect of such Security and express mention of the payment of Liquidated
Damages (if applicable) in any provisions of this Security shall not be
construed as excluding Liquidated Damages in those provisions of this Security
where such express mention is not made.

      If this Security is a Registrable Security and the Holder of this Security
(including any Person that has a beneficial interest in this Security) elects to
sell this Security pursuant to the Shelf Registration Statement then, by its
acceptance hereof, such Holder of this Security agrees to be bound by the terms
of the Registration Rights Agreement relating to the Registrable Securities
which are the subject of such election.

      If a Change in Control occurs, the Holder of this Security, at the
Holder's option, shall have the right, in accordance with the provisions of the
Indenture, to require the Company to repurchase this Security (or any portion of
the principal amount hereof that is at least $1,000 or an integral multiple of
$1,000 in excess thereof, provided that the portion of the principal amount of
this Security to be Outstanding after such repurchase is at least equal to
U.S.$1,000) for cash at a

                                                                            -26-
<PAGE>
Repurchase Price equal to 100% of the principal amount thereof plus interest
accrued to the Repurchase Date. Whenever in this Security there is a reference,
in any context, to the principal of any Security as of any time, such reference
shall be deemed to include reference to the Repurchase Price payable in respect
of such Security to the extent that such Repurchase Price is, was or would be so
payable at such time, and express mention of the Repurchase Price in any
provision of this Security shall not be construed as excluding the Repurchase
Price so payable in those provisions of this Security when such express mention
is not made.

      In the event of a deposit or withdrawal of an interest in this Security,
including an exchange, transfer, redemption, repurchase or conversion of this
Security in part only, the Trustee, as custodian of the Depositary, shall make
an adjustment on its records to reflect such deposit or withdrawal in accordance
with the Applicable Procedures.

      The indebtedness evidenced by this Security is, to the extent and in the
manner provided in the Indenture, subordinate and subject in right of payment to
the prior payment in full of all Senior Debt of the Company, and this Security
is issued subject to such provisions of the Indenture with respect thereto. Each
Holder of this Security, by accepting the same, (a) agrees to and shall be bound
by such provisions, (b) authorizes and directs the Trustee on his behalf to take
such action as may be necessary or appropriate to effectuate the subordination
so provided and (c) appoints the Trustee his attorney-in-fact for any and all
such purposes.

      If an Event of Default shall occur and be continuing, the principal of all
the Securities, together with accrued interest to the date of declaration, may
be declared due and payable in the manner and with the effect provided in the
Indenture. Upon payment (i) of the amount of principal so declared due and
payable, together with accrued interest to the date of declaration, and (ii) of
interest on any overdue principal and, to the extent permitted by applicable
law, overdue interest, all of the Company's obligations in respect of the
payment of the principal of and interest on the Securities shall terminate.

      The Indenture permits, with certain exceptions as therein provided, the
amendment thereof and the modification of the rights and obligations of the
Company and the rights of the Holders of the Securities under the Indenture at
any time by the Company and the Trustee with either (a) the written consent of
the Holders of not less than a majority in principal amount of the Securities at
the time Outstanding, or (b) by the adoption of a resolution, at a meeting of
Holders of the Outstanding Securities at which a quorum is present, by the
Holders of at least 66 2/3% in aggregate principal amount of the Outstanding
Securities represented and entitled to vote at such meeting. The Indenture also
contains provisions permitting the Holders of specified percentages in principal
amount of the Securities at the time Outstanding, on behalf of the Holders of
all the Securities, to waive compliance by the Company with certain provisions
of the Indenture and certain past defaults under the Indenture and their
consequences. Any such consent or waiver by the Holder of this Security shall be
conclusive and binding upon such Holder and upon all future Holders of this
Security and of any Security issued in exchange therefore or in lieu hereof
whether or not notation of such consent or waiver is made upon this Security or
such other Security. Certain modifications or amendments to the Indenture
require the consent of the Holder of each Outstanding Security affected.

                                                                            -27-

Trustee written notice of a continuing Event of Default, the Holders of not less
than 25% in principal amount of the Outstanding Securities shall have made
written request to the Trustee to institute proceedings in respect of such Event
of Default as Trustee and offered the Trustee reasonable indemnity and the
Trustee shall not have received from the Holders of a majority in principal
amount of the Securities Outstanding a direction inconsistent with such request,
and shall have failed to institute any such proceeding, for 60 days after
receipt of such notice, request and offer of indemnity. The foregoing shall not
apply to any suit instituted by the Holder of this Security for the enforcement
of any payment of principal hereof, premiums if any, or interest (including
Liquidated Damages) hereon on or after the respective due dates expressed herein
or for the enforcement of the right to convert this Security as provided in the
Indenture.

set forth, the transfer of this Security is registrable on the Security Register

such other offices or agencies as the Company may designate, duly endorsed by,
or accompanied by a written instrument of transfer in form satisfactory to the
Company and the Security Registrar duly executed by, the Holder thereof or his
attorney duly authorized in writing, and thereupon one or more new Securities,
of authorized denominations and for the same aggregate principal amount, will be
issued to the designated transferee or transferees by the Registrar. No service
charge shall be made for any such registration of transfer or exchange, but the
Company may require payment of a sum sufficient to recover any tax or other
governmental charge payable in connection therewith.

      Prior to due presentation of this Security for registration of transfer,
the Company, the Trustee and any agent of the Company or the Trustee may treat
the Person in whose name such Security is registered, as the owner thereof for
all purposes, whether or not such Security be overdue, and neither the Company,
the Trustee nor any such agent shall be affected by notice to the contrary.

interest on this Security and no recourse under or upon any obligation, covenant
or agreement of the Company in the Indenture or any indenture supplemental
thereto or in any Security, or because of the creation of any indebtedness
represented thereby, shall be had against any incorporator, stockholder,
employee, agent, officer or director or subsidiary, as such, past, present or
future, of the Company or of any successor corporation, either directly or
through the Company or any successor corporation, whether

SECTION 3.1 Title and Terms.

      The aggregate principal amount of Securities which may be authenticated

up to an additional $15,000,000 such that the total aggregate principal amount
of Securities which may be authenticated and delivered under this Indenture
shall not exceed U.S. $100,000,000 of Securities from the Company, except for
Securities authenticated and delivered pursuant to Section 3.4, 3.5, 3.6, 8.5,
12.2 or 14.2(5) in exchange for, or in lieu of, other Securities previously
authenticated and delivered under this Indenture.

      (1) The Securities shall be known and designated as the "4.25% Convertible
Subordinated Notes due July 1, 2008" of the Company. Their Stated Maturity shall
be July 1, 2008 and they shall bear interest on their principal amount from July
1, 2003, payable semi-annually in arrears on January 1 and July 1 in each year,
commencing January 1, 2004, at the rate of 4.25% per annum until the principal
thereof is due and at the rate of 4.25% per annum on any overdue principal and,
to the extent permitted by law, on any overdue interest; provided, however, that

      The Securities shall be redeemable at the option of the Company at any
time on or after July 1, 2005, in whole or in part, subject to the conditions
and as otherwise provided in Article XI and in the form of Security set forth in

<PAGE>
SECTION 3.2 Denominations.

      The Securities shall be issuable only in registered form, without coupons,
in denominations of U.S.$1,000 and integral multiples of U.S.$1,000 in excess
thereof.

SECTION 3.3 Execution, Authentication, Delivery and Dating.

      The Securities shall be executed on behalf of the Company by its Chairman
of the Board, its Vice Chairman of the Board, its Chief Executive Officer, its
President, one of its Executive Vice Presidents, one of its Senior Vice
Presidents or one of its Vice Presidents, and attested by its Chief Financial
Officer, Secretary or one of its Assistant Secretaries. Any such signature may
be manual or facsimile.

      Securities bearing the manual or facsimile signature of individuals who
were at any time the proper officers of the Company shall bind the Company,
notwithstanding that such individuals or any of them have ceased to hold such
offices prior to the authentication and delivery of such Securities or did not
hold such offices at the date of such Securities.

      At any time and from time to time after the execution and delivery of this
Indenture, the Company may deliver Securities executed by the Company to the
Trustee or to its order for authentication, together with a Company Order for
the authentication and delivery of such Securities, and the Trustee in
accordance with such Company Order shall authenticate and make available for
delivery such Securities as in this Indenture provided.

      Each Security shall be dated the date of its authentication.

      No Security shall be entitled to any benefit under this Indenture or be
valid or obligatory for any purpose unless there appears on such Security a
certificate of authentication substantially in the form provided for herein
executed by the Trustee by manual signature of an authorized signatory, and such
certificate upon any Security shall be conclusive evidence, and the only
evidence, that such Security has been duly authenticated and delivered
hereunder.

SECTION 3.4 Global Securities; Non-global Securities; Book-entry Provisions.

      (1) Global Securities

            (i) Each Global Security authenticated under this Indenture shall be
registered in the name of the Depositary designated by the Company for such
Global Security or a nominee thereof and delivered to such Depositary or a
nominee thereof or custodian therefor, and each such Global Security shall
constitute a single Security for all purposes of this Indenture.

            (ii) Except for exchanges of Global Securities for definitive,
Non-global Securities at the sole discretion of the Company, no Global Security
may be exchanged in whole or in part for Securities registered, and no transfer
of a Global Security in whole or in part may be registered, in the name of any
Person other than the Depositary for such Global Security or a

                                                                            -35-
<PAGE>
nominee thereof unless (A) such Depositary (i) has notified the Company that it
is unwilling or unable to continue as Depositary for such Global Security or
(ii) has ceased to be a clearing agency registered as such under the Exchange
Act or announces an intention permanently to cease business or does in fact do
so or (B) there shall have occurred and be continuing an Event of Default with
respect to such Global Security. In such event, if a successor Depositary for
such Global Security is not appointed by the Company within 90 days after the
Company receives such notice or becomes aware of such ineligibility, the Company
will execute, and the Trustee, upon receipt of an Officers' Certificate
directing the authentication and delivery of Securities, will authenticate and
deliver, Securities, in any authorized denominations in an aggregate principal
amount equal to the principal amount of such Global Security in exchange for
such Global Security.

            (iii) If any Global Security is to be exchanged for other Securities
or canceled in whole, it shall be surrendered by or on behalf of the Depositary
or its nominee to the Trustee, as Security Registrar, for exchange or
cancellation, as provided in this Article III. If any Global Security is to be
exchanged for other Securities or canceled in part, or if another Security is to
be exchanged in whole or in part for a beneficial interest in any Global
Security, in each case, as provided in Section 3.5, then either (A) such Global
Security shall be so surrendered for exchange or cancellation, as provided in
this Article III, or (B) the principal amount thereof shall be reduced or
increased by an amount equal to the portion thereof to be so exchanged or
canceled, or equal to the principal amount of such other Security to be so
exchanged for a beneficial interest therein, as the case may be, by means of an
appropriate adjustment made on the records of the Trustee, as Security
Registrar, whereupon the Trustee, in accordance with the Applicable Procedures,
shall instruct the Depositary or its authorized representative to make a
corresponding adjustment to its records. Upon any such surrender or adjustment
of a Global Security, the Trustee shall, subject to Section 3.5(3) and as
otherwise provided in this Article III, authenticate and deliver any Securities
issuable in exchange for such Global Security (or any portion thereof) to or
upon the order of, and registered in such names as may be directed by, the
Depositary or its authorized representative. Upon the request of the Trustee in
connection with the occurrence of any of the events specified in the preceding
paragraph, the Company shall promptly make available to the Trustee a reasonable
supply of Securities that are not in the form of Global Securities. The Trustee
shall be entitled to rely upon any order, direction or request of the Depositary
or its authorized representative which is given or made pursuant to this Article
III if such order, direction or request is given or made in accordance with the
Applicable Procedures.

            (iv) Every Security authenticated and delivered upon registration of
transfer of, or in exchange for or in lieu of, a Global Security or any portion
thereof, whether pursuant to this Article III or otherwise, shall be
authenticated and delivered in the form of, and shall be, a registered Global
Security, unless such Security is registered in the name of a Person other than
the Depositary for such Global Security or a nominee thereof, in which case such
Security shall be authenticated and delivered in definitive, fully registered
form, without interest coupons.

            (v) The Depositary or its nominee, as registered owner of a Global
Security, shall be the Holder of such Global Security for all purposes under the
Indenture and the Securities, and owners of beneficial interests in a Global
Security shall hold such interests pursuant to the

                                                                            -36-
<PAGE>
Applicable Procedures. Accordingly, any such owner's beneficial interest in a
Global Security will be shown only on, and the transfer of such interest shall
be effected only through, records maintained by the Depositary or its nominee or
its Agent Members and such owners of beneficial interests in a Global Security
will not be considered the owners or holders thereof.

      (2) Non-global Securities. Securities issued upon the events described in
Section 3.4(l)(ii) shall be in definitive, fully registered form, without
interest coupons, and shall bear the Restricted Securities Legend if and as
required by this Indenture.

SECTION 3.5 Registration; Registration of Transfer and Exchange; Restrictions on
            Transfer.

      (1) The Company shall cause to be kept at the Corporate Trust Office of
the Trustee a register (the register maintained in such office referred to as
the "Security Register") in which, subject to such reasonable regulations as it
may prescribe, the Company shall provide for the registration of Securities and
of transfers of Securities. The Trustee is hereby appointed "Security Registrar"
for the purpose of registering Securities and transfers and exchanges of
Securities as herein provided.

      Upon surrender for registration of transfer of any Security at an office
or agency of the Company designated pursuant to Section 10.2 for such purpose,
the Company shall execute, and the Trustee shall authenticate and deliver, in
the name of the designated transferee or transferees, one or more new Securities
of any authorized denominations and of a like aggregate principal amount and
bearing such restrictive legends as may be required by this Indenture.

      At the option of the Holder, and subject to the other provisions of this
Section 3.5, Securities may be exchanged for other Securities of any authorized
denomination and of a like aggregate principal amount, upon surrender of the
Securities to be exchanged at any such office or agency. Whenever any Securities
are so surrendered for exchange, and subject to the other provisions of this
Section 3.5, the Company shall execute, and the Trustee shall authenticate and
deliver, the Securities that the Holder making the exchange is entitled to
receive. Every Security presented or surrendered for registration of transfer or
for exchange shall (if so required by the Company or the Security Registrar) be
duly endorsed, or be accompanied by a written instrument of transfer in form
satisfactory to the Company, the Trustee and the Security Registrar, duly
executed by the Holder thereof or his attorney duly authorized in writing.

      All Securities issued upon any registration of transfer or exchange of
Securities shall be the valid obligations of the Company, evidencing the same
debt and entitled to the same benefits under this Indenture as the Securities
surrendered upon such registration of transfer or exchange.

      No service charge shall be made to a Holder for any registration of
transfer or exchange of Securities except as provided in Section 3.6, but the
Company may require payment of a sum sufficient to cover any tax or other
governmental charge that may be imposed in connection with any registration of
transfer or exchange of Securities, other than exchanges pursuant to Section
3.4, 8.5, 12.2 or 14.2 (other than where the shares of Common Stock are to be
issued or delivered in a name

                                                                            -37-

other than that of the Holder of the Security) not involving any transfer and
other than any stamp and other duties, if any, which may be imposed in
connection with any such transfer or exchange by the United States or any
political subdivision thereof or therein, which shall be paid by the Company.

      In the event of a redemption of the Securities, neither the Company nor
the Securities Registrar will be required (a) to register the transfer of or
exchange Securities for a period of 15 days immediately preceding the date
notice is given identifying the serial numbers of the Securities called for such
redemption or (b) to register the transfer of or exchange any Security, or

      (2) Certain Transfers and Exchanges. Notwithstanding any other provision
of this Indenture or the Securities, transfers and exchanges of Securities and
beneficial interests in a Global Security of the kinds specified in this Section
3.5(2) shall be made only in accordance with this Section 3.5(2).

            (i) Restricted Global Security to Restricted Non-global Security. In
the event that Non-global Securities are to be issued pursuant to Section
3.4(1)(ii) in connection with any transfer of Securities, such transfer may be
effected only in accordance with the provisions of this Clause (2)(i) and
subject to the Applicable Procedures. Upon receipt by the Trustee, as Security
Registrar, of (A) a Company Order from the Company directing the Trustee, as
Security Registrar, to (x) authenticate and deliver one or more Securities of
the same aggregate principal amount as the beneficial interest in the Restricted
Global Security to be transferred, such instructions to contain the name or
names of the designated transferee or transferees, the authorized denomination
or denominations of the Securities to be so issued and appropriate delivery
instructions and (y) decrease the beneficial interest of a specified Agent
Member's account in a Restricted Global Security by a specified principal amount
not greater than the principal amount of such Restricted Global Security, and
(B) such other certifications, legal opinions or other information as the
Company or the Trustee may reasonably require to confirm that such transfer is
being made pursuant to an exemption from, or in a transaction not subject to,
the registration requirements of the Securities Act, then the Trustee, as
Security Registrar, shall decrease the principal amount of the Restricted Global
Security by the specified amount and authenticate and deliver Securities in
accordance with such instructions from the Company as provided in Section
3.4(1)(iii).

            (ii) Restricted Non-global Security to Restricted Global Security.
If the Holder of a Restricted Security (other than a Global Security) wishes at
any time to transfer all or any portion of such Restricted Security to a Person
who wishes to take delivery thereof in the form of a beneficial interest in the
Restricted Global Security, such transfer may be effected only in accordance
with the provisions of this Clause (2)(ii) and subject to the Applicable
Procedures. Upon receipt by the Trustee, as Security Registrar, of such
Restricted Security as provided in Section 3.5(1) and instructions from the
Company directing that a beneficial interest in the Restricted Global Security
in a specified principal amount not greater than the principal amount of such
Security be credited to a specified Agent Member's account, then the Trustee, as
Security Registrar, shall cancel such Restricted Security (and issue a new
Restricted Security in respect of any

                                                                            -38-

untransferred portion thereof) as provided in Section 3.5(1) and increase the
principal amount of the Restricted Global Security by the specified principal
amount as provided in Section 3.4(1)(iii).

            (iii) Exchanges Between Global Security and Non-global Security. A
beneficial interest in a Global Security may be exchanged for a Security that is
not a Global Security only as provided in Section 3.4 or only if such exchange
occurs in connection with a transfer effected in accordance with Clause 2(i)
above, provided that, if such interest is a beneficial interest in the
Restricted Global Security, then such interest shall be exchanged for a
Restricted Security (subject in each case to Section 3.5(3)). A Security that is
not a Global Security may be exchanged for a beneficial interest in a Global
Security only if such exchange occurs in connection with a transfer effected in
accordance with Clause (2)(ii) above.

            (iv) Upon the initial distribution of the Securities as contemplated
by the Purchase Agreement to Sprout Group and its affiliates such Securities
will be issued in the form of one or more Restricted non-Global Securities (the
"Sprout Certificated Securities") in definitive, fully registered form without
interest coupons and bearing the Restricted Securities Legend. Transfers and
exchanges of any Sprout Certificated Securities or Sprout Restricted Non-Global
Securities shall be made only in accordance with this Section 3.5(2)(iv).

                  (a) Sprout Certificated Security to Global Security. In the
event that Global Securities are to be issued pursuant to Section 3.4(1)(iii) in
connection with any transfer of Sprout Certificated Securities, such transfer
may be effected only in accordance with the provisions of this Clause (2)(iv)(a)
and subject to the Applicable Procedures. Upon receipt by the Trustee, as
Security Registrar, of (A) a Company Order from the Company directing that a
beneficial interest in the Global Security in a specified principal amount not
greater than the principal amount (or portion thereof) of such Sprout
Certificated Security to be transferred be credited to a specified Agent
Member's account, such instructions to contain the name or names of the
designated transferee or transferees, the authorized denomination or
denominations of the Securities to be so issued and appropriate delivery
instructions, and (B) such other certifications, legal opinions or other
information as the Company or the Trustee may reasonably require to confirm that
such transfer is being made pursuant to Rule 144 of the Securities Act or the
registration requirements of the Securities Act, then the Trustee, as Security
Registrar, shall cancel such Sprout Certificated Security (and issue a new
Sprout Certificated Security in respect of any untransferred portion thereof) as
provided in Section 3.5(1) and increase the principal amount of the Global
Security by the specified principal amount as provided in Section 3.4(1)(iii).

                  (b) Sprout Certificated Security or Sprout Restricted
Non-Global Security to Sprout Restricted Non-Global Security. If the Holder of a
Sprout Certificated Security or Sprout Restricted Non-Global Security wishes at
any time to transfer all or any portion of such Sprout Certificated Security or
Sprout Restricted Non-Global Security to a Person who wishes to take delivery
thereof in the form of a Sprout Restricted Non-Global Security, such transfer
may be effected only in accordance with the provisions of this Clause (2)(iv)(b)
and subject to the Applicable Procedures. Upon receipt by the Trustee, as
Security Registrar, of (A) a Company Order from the Company directing the
Trustee, as Security Registrar, to authenticate and deliver one or

                                                                            -39-

more Sprout Restricted Non-Global Securities of the same aggregate principal
amount (or portion thereof) as the Sprout Certificated Security or Sprout
Restricted Non-Global Security to be transferred, such instructions to contain
the name or names of the designated transferee or transferees, the authorized
denomination or denominations of the Sprout Restricted Non-Global Securities to
be so issued and appropriate delivery instructions, and (B) such other
certifications, legal opinions or other information as the Company or the
Trustee may reasonably require to confirm that such transfer is being made
pursuant to an exemption from Securities Act, then the Trustee shall cancel such
Sprout Certificated Security or Sprout Restricted Non-Global Security (and issue
a new Sprout Certificated Security or Sprout Restricted Non-Global Security in
respect of any untransferred portion thereof) as provided in Section 3.5(1) and
deliver Sprout Restricted Non-Global Securities in accordance with such
instructions from the Company as provided in Section 3.4(1)(iii).

                  (c) Sprout Restricted Non-Global Securities to Global
Security. In the event that Global Securities are to be issued pursuant to
Section 3.4(1)(iii) in connection with any transfer or exchange of Sprout
Restricted Non-Global Securities, such transfer may be effected only in
accordance with the provisions of this Clause (2)(iv)(c) and subject to the
Applicable Procedures. Upon receipt by the Trustee, as Security Registrar, of
(A) a Company Order from the Company directing that a beneficial interest in the
Global Security in a specified principal amount not greater than the principal
amount (or portion thereof) of such Sprout Restricted Non-Global Securities to
be transferred or exchanged be credited to a specified Agent Member's account,
such instructions to contain the name or names of the designated transferee or
transferees, the authorized denomination or denominations of the Securities to
be so issued and appropriate delivery instructions, and (B) such other
certifications, legal opinions or other information as the Company or the
Trustee may reasonably require to confirm that such transfer is being made
pursuant to Rule 144 of the Securities Act or the registration requirements of
the Securities Act, then the Trustee, as Security Registrar, shall cancel such
Sprout Restricted Non-Global Securities (and issue a new Sprout Restricted
Non-Global Securities in respect of any untransferred or unexchanged portion
thereof) as provided in Section 3.5(1) and increase the principal amount of the
Global Security by the specified principal amount as provided in Section
3.4(1)(iii).

      (3) Securities Act Legends. All Securities issued pursuant to this
Indenture, and all Successor Securities, shall bear the Restricted Securities
Legend, subject to the following:

            (i) subject to the following Clauses of this Section 3.5(3), a
Security or any portion thereof which is exchanged, upon transfer or otherwise,
for a Global Security or any portion thereof shall bear the Restricted
Securities Legend borne by such Global Security for which the Security was
exchanged;

            (ii) subject to the following Clauses of this Section 3.5(3), a new
Security that is not a Global Security and is issued in exchange for another
Security (including a Global Security) or any portion thereof, upon transfer or
otherwise, shall bear the Restricted Securities Legend borne by the Security for
which the new Security was exchanged;

                                                                            -40-

<PAGE>

            (iii) any Securities that are sold or otherwise disposed of pursuant
to an effective registration statement under the Securities Act (including the
Shelf Registration Statement), together with their Successor Securities shall
not bear a Restricted Securities Legend; the Company shall inform the Trustee in
writing of the effective date of any such registration statement registering the
Securities under the Securities Act and shall notify the Trustee at any time
when prospectuses must be delivered with respect to Securities to be sold
pursuant to such registration statement. The Trustee shall not be liable for any
action taken or omitted to be taken by it in good faith in accordance with the
aforementioned registration statement;

            (iv) at any time after the Securities may be freely transferred
without registration under the Securities Act or without being subject to
transfer restrictions pursuant to the Securities Act, a new Security that does
not bear a Restricted Securities Legend may be issued in exchange for or in lieu
of a Security (other than a Global Security) or any portion thereof that bears
such a legend if the Trustee has received an Unrestricted Securities
Certificate, satisfactory to the Trustee and duly executed by the Holder of such
Security bearing a Restricted Securities Legend or his attorney duly authorized
in writing, and after such date and receipt of such certificate, the Trustee
shall authenticate and deliver such new Security in exchange for or in lieu of
such other Security as provided in this Article III;

            (v) a new Security that does not bear a Restricted Securities Legend
may be issued in exchange for or in lieu of a Security or any portion thereof
that bears such a legend if, in the Company's judgment, placing such a legend
upon such new Security is not necessary to ensure compliance with the
registration requirements of the Securities Act, and the Trustee, at the
direction of the Company, shall authenticate and deliver such a new Security as
provided in this Article III; and

            (vi) notwithstanding the foregoing provisions of this Section
3.5(3), a Successor Security of a Security that does not bear a Restricted
Securities Legend shall not bear such legend unless the Company has reasonable
cause to believe that such Successor Security is a "restricted security" within
the meaning of Rule 144, in which case the Trustee, at the direction of the
Company, shall authenticate and deliver a new Security bearing a Restricted
Securities Legend in exchange for such Successor Security as provided in this
Article III.

      (4) Any stock certificate representing shares of Common Stock issued upon
conversion of the Securities shall bear the Restricted Securities Legend borne
by such Securities, to the extent required by this Indenture, unless such shares
of Common Stock have been sold pursuant to a registration statement that has
been declared effective under the Securities Act (including the Shelf
Registration Statement) (and that continues to be effective at the time of such
transfer) or sold pursuant to Rule 144(k) of the Securities Act, or unless
otherwise agreed by the Company in writing with written notice thereof to the
transfer agent for the Common Stock. With respect to the transfer of shares of
Common Stock issued upon conversion of the Securities that are restricted
hereunder, any deliveries of certificates, legal opinions or other instruments
that would be required to be made to the Security Registrar in the case of a
transfer of Securities, as described above, shall instead be made to the
transfer agent for the Common Stock.

                                                                            -41-

      (5) Neither the Trustee, the Paying Agent nor any of their agents shall
(i) have any duty to monitor compliance with or with respect to any federal or
state or other securities or tax laws or (ii) have any duty to obtain
documentation on any transfers or exchanges other than as specifically required
hereunder.

SECTION 3.6 Mutilated, Destroyed, Lost or Stolen Securities.

      If any mutilated Security is surrendered to the Trustee, the Company shall
execute and the Trustee shall authenticate and deliver in exchange therefor a
new Security of like tenor and principal amount and bearing a number not
contemporaneously outstanding.

      If there be delivered to the Company and to the Trustee:

      (1) evidence to their satisfaction of the destruction, loss or theft of
any Security, and

      (2) such security or indemnity as may be satisfactory to the Company and
the Trustee to save each of them and any agent of either of them harmless,

then, in the absence of actual notice to the Company or the Trustee that such
Security has been acquired by a bona fide purchaser, the Company shall execute
and the Trustee shall authenticate and deliver, in lieu of any such destroyed,
lost or stolen Security, a new Security of like tenor and principal amount and
bearing a number not contemporaneously outstanding.

      In case any such mutilated, destroyed, lost or stolen Security has become
or is about to become due and payable, the Company in its discretion, but
subject to any conversion rights, may, instead of issuing a new Security, pay
such Security, upon satisfaction of the conditions set forth in the preceding
paragraph.

      Upon the issuance of any new Security under this Section 3.6, the Company
may require the payment of a sum sufficient to cover any tax or other
governmental charge that may be imposed in relation thereto (other than any
stamp and other duties, if any, which may be imposed in connection therewith by
the United States or any political subdivision thereof or therein, which shall
be paid by the Company) and any other expenses (including the fees and expenses
of the Trustee) connected therewith.

      Every new Security issued pursuant to this Section 3.6 in lieu of any
mutilated, destroyed, lost or stolen Security shall constitute an original
additional contractual obligation of the Company, whether or not the mutilated,
destroyed, lost or stolen Security shall be at any time enforceable by anyone,
and such new Security shall be entitled to all the benefits of this Indenture
equally and proportionately with any and all other Securities duly issued
hereunder.

      The provisions of this Section 3.6 are exclusive and shall preclude (to
the extent lawful) all other rights and remedies of any Holder with respect to
the replacement or payment of mutilated, destroyed, lost or stolen Securities.

                                                                            -42-

SECTION 3.7 Payment of Interest; Interest Rights Preserved.

      Subject to the last paragraph of this Section, interest or Liquidated
Damages on any Security that is payable, and is punctually paid or duly provided
for, on any Interest Payment Date shall be paid to the Person in whose name that
Security (or one or more Predecessor Securities) is registered at the close of
business on the Regular Record Date for such interest.

      Any interest or Liquidated Damages on any Security that is payable, but is
not punctually paid or duly provided for, on any Interest Payment Date (herein
called "Defaulted Interest") shall forthwith cease to be payable to the Holder
on the relevant Regular Record Date by virtue of having been such Holder, and
such Defaulted Interest may be paid by the Company, at its election in each
case, as provided in Clause (1) or (2) below:

      (1) The Company may elect to make payment of any Defaulted Interest to the
Persons in whose names the Securities (or their respective Predecessor
Securities) are registered at the close of business on a "Special Record Date"
for the payment of such Defaulted Interest, which shall be fixed in the
following manner. The Company shall notify the Trustee in writing of the amount
of Defaulted Interest proposed to be paid on each Security, the date of the
proposed payment and the Special Record Date, and at the same time the Company
shall deposit with the Trustee an amount of money equal to the aggregate amount
proposed to be paid in respect of such Defaulted Interest or shall make
arrangements satisfactory to the Trustee for such deposit prior to the date of
the proposed payment, such money when deposited to be held in trust for the
benefit of the Persons entitled to such Defaulted Interest as in this Clause
provided. The Special Record Date for the payment of such Defaulted Interest
shall be not more than 15 days and not less than 10 days prior to the date of
the proposed payment and not less than 10 days after the receipt by the Trustee
of the notice of the proposed payment. The Trustee, in the name and at the
expense of the Company, shall cause notice of the proposed payment of such
Defaulted Interest and the Special Record Date therefor to be mailed,
first-class postage prepaid, to each Holder at such Holder's address as it
appears in the Security Register, not less than 10 days prior to such Special
Record Date. Notice of the proposed payment of such Defaulted Interest and the
Special Record Date therefor having been so mailed, such Defaulted Interest
shall be paid to the Persons in whose names the Securities (or their respective
Predecessor Securities) are registered at the close of business on such Special
Record Date and shall no longer be payable pursuant to the following Clause (2).

      (2) The Company may make payment of any Defaulted Interest in any other
lawful manner not inconsistent with the requirements of any securities exchange
on which the Securities may be listed, and upon such notice as may be required
by such exchange, if, after notice given by the Company to the Trustee of the
proposed payment pursuant to this Clause, such manner of payment shall be deemed
practicable by the Trustee.

      Subject to the provisions of this Section 3.7 and Section 3.5, each
Security delivered under this Indenture upon registration of transfer of or in
exchange for or in lieu of any other Security shall carry the rights to interest
accrued and unpaid, and to accrue, which were carried by such other Security.

                                                                            -43-

      Interest on any Security that is converted in accordance with Section 12.2
during a Record Date Period shall be payable in accordance with the provisions
of Section 12.2.

SECTION 3.8 Persons Deemed Owners.

      Prior to due presentment of a Security for registration of transfer, the
Company, the Trustee, any Paying Agent and any agent of the Company, the Trustee
or any Paying Agent may treat the Person in whose name such Security is
registered as the owner of such Security for the purpose of receiving payment of
principal of, premium, if any, and (subject to Section 3.7) interest or
Liquidated Damages on such Security and for all other purposes whatsoever,
whether or not such Security be overdue, and neither the Company, the Trustee,
any Paying Agent nor any agent of the Company, the Trustee or any Paying Agent
shall be affected by notice to the contrary.

SECTION 3.9 Cancellation.

      All Securities surrendered for payment, redemption, repurchase,
registration of transfer or exchange or conversion shall, if surrendered to any
Person other than the Trustee, be delivered to the Trustee. All Securities so
delivered to the Trustee shall be canceled promptly by the Trustee (or its
agent). No Securities shall be authenticated in lieu of or in exchange for any
Securities canceled as provided in this Section 3.9. The Trustee shall dispose
of all canceled Securities in accordance with applicable law and its customary
practices in effect from time to time.

SECTION 3.10 Computation of Interest.

      Interest on the Securities (including any Liquidated Damages) shall be
computed on the basis of a 360-day year of twelve 30-day months.

SECTION 3.11 CUSIP Numbers.

      The Company in issuing Securities may use "CUSIP" numbers (if then
generally in use) in addition to serial numbers; if so, the Trustee shall use
such CUSIP numbers in addition to serial numbers in notices of redemption and
repurchase as a convenience to Holders; provided that any such notice may state
that no representation is made as to the correctness of such CUSIP numbers
either as printed on the Securities or as contained in any notice of a
redemption or repurchase and that reliance may be placed only on the serial or
other identification numbers printed on the Securities, and any such redemption
or repurchase shall not be affected by any defect in or omission of such CUSIP
numbers.

debts generally as they become due, or the taking of corporate action by the
Company or any Subsidiary in furtherance of any such action.

SECTION 5.2 Acceleration of Maturity; Rescission and Annulment.

      If an Event of Default (other than an Event of Default specified in
Section 5.1(6) or 5.1(7) with respect to the Company) occurs and is continuing,
then in every such case the Trustee or the Holders of not less than 25% in
principal amount of the Outstanding Securities may, subject to the provisions of
Article XIII, declare the principal of all the Securities to be due and payable
immediately, by a notice in writing to the Company (and to the Trustee if given
by the Holders), and upon any such declaration such principal and all accrued
interest thereon shall become immediately due and payable. If an Event of
Default specified in Section 5.1(6) or 5.1(7) with respect to the Company
occurs, the principal of, and accrued interest on, all the Securities shall,
subject to the provisions of Article XIII, ipso facto become immediately due and
payable without any declaration or other Act of the Holders or any act on the
part of the Trustee.

      At any time after such declaration of acceleration has been made and
before a judgment or decree for payment of the money due has been obtained by
the Trustee as hereinafter in this Article V provided, the Holders of a majority
in principal amount of the Outstanding Securities, by written notice to the
Company and the Trustee, may, on behalf of all Holders, rescind and annul such
declaration and its consequences if:

      (1) the Company has paid or deposited with the Trustee a sum sufficient to
pay

            (i) all overdue interest on all Securities,

            (ii) the principal of and premium, if any, on any Securities that
have become due otherwise than by such declaration of acceleration and any
interest thereon at the rate borne by the Securities,

            (iii) to the extent permitted by applicable law, interest upon
overdue interest at a rate of 4.25% per annum, and

            (iv) all sums paid or advanced by the Trustee hereunder and the
reasonable compensation, expenses, disbursements and advances of the Trustee,
its agents and counsel;

      (2) all Events of Default, other than the nonpayment of the principal of
and any premium and interest on, Securities which have become due solely by such
declaration of acceleration, have been cured or waived as provided in Section
5.13; and

      (3) such rescission and annulment would not conflict with any judgment or
decree issued in appropriate judicial proceedings regarding the payment by the
Trustee to the Holders of the amounts referred to in 5.2(1).

                                                                            -48-
<PAGE>
      No rescission or annulment referred to above shall affect any subsequent
default or impair any right consequent thereon.

SECTION 5.3 Collection of Indebtedness and Suits for Enforcement by Trustee.

      The Company covenants that if:

      (1) default is made in the payment of any interest (including any
Liquidated Damages) on any Security when it becomes due and payable and such
default continues for a period of 45 days, or

      (2) default is made in the payment of the principal of or premium, if any,
on any Security at the Maturity thereof, the Company will, upon demand of the
Trustee but subject to the provisions of Article XIII, pay to it, for the
benefit of the Holders of such Securities the whole amount then due and payable
on such Securities for principal and interest (including any Liquidated Damages)
and interest on any overdue principal and premium, if any, and, to the extent
permitted by applicable law, on any overdue interest (including any Liquidated
Damages), at a rate of 4.25% per annum, and in addition thereto, such further
amount as shall be sufficient to cover the reasonable costs and expenses of
collection, including the reasonable compensation, expenses, disbursements and
advances of the Trustee, its agents and counsel.

      If the Company fails to pay such amounts forthwith upon such demand, the
Trustee, in its own name and as trustee of an express trust, may institute a
judicial proceeding for the collection of the sums so due and unpaid, may
prosecute such proceeding to judgment or final decree and may enforce the same
against the Company or any other obligor upon the Securities and collect the
moneys adjudged or decreed to be payable in the manner provided by law out of
the property of the Company or any other obligor upon the Securities, wherever
situated.

      If an Event of Default occurs and is continuing, the Trustee may in its
discretion proceed to protect and enforce its rights and the rights of the
Holders of Securities by such appropriate judicial proceedings as the Trustee
shall deem most effectual to protect and enforce any such rights, whether for
the specific enforcement of any covenant or agreement in this Indenture or in
aid of the exercise of any power granted herein, or to enforce any other proper
remedy.

SECTION 5.4 Trustee May File Proofs of Claim.

      In case of the pendency of any receivership, insolvency, liquidation,
bankruptcy, reorganization, arrangement, adjustment, composition or other
judicial proceeding relative to the Company or any other obligor upon the
Securities or the property of the Company or of such other obligor or the
creditors of either, the Trustee (irrespective of whether the principal of, and
any interest on, the Securities shall then be due and payable as therein
expressed or by declaration or otherwise and irrespective of whether the Trustee
shall have made any demand on the Company for the payment of overdue principal
or interest) shall be entitled and empowered, by intervention in such proceeding
or otherwise,

                                                                            -49-
<PAGE>
      (1) to file a proof of claim for the whole amount of principal, premium,
if any, and interest owing and unpaid in respect of the Securities and take such
other actions, including participating as a member, voting or otherwise, of any
official committee of creditors appointed in such matter, and to file such other
papers or documents, in each of the foregoing cases, as may be necessary or
advisable in order to have the claims of the Trustee (including any claim for
the reasonable compensation, expenses, disbursements and advances of the
Trustee, its agents and counsel) and of the Holders of Securities allowed in
such judicial proceeding, and

      (2) to collect and receive any moneys or other property payable or
deliverable on any such claim and to distribute the same; and any custodian,
receiver, assignee, trustee, liquidator, sequestrator or other similar official
in any such judicial proceeding is hereby authorized by each Holder of
Securities to make such payments to the Trustee and, in the event that the
Trustee shall consent to the making of such payments directly to the Holders of
Securities to pay to the Trustee any amount due to it for the reasonable
compensation, expenses, disbursements and advances of the Trustee, its agents
and counsel and any other amounts due the Trustee under Section 6.7.

      Nothing herein contained shall be deemed to authorize the Trustee to
authorize or consent to or accept or adopt on behalf of any Holder of a Security
any plan of reorganization, arrangement, adjustment or composition affecting the
Securities or the rights of any Holder thereof or to authorize the Trustee to
vote in respect of the claim of any Holder of a Security in any such proceeding;
provided, however, that the Trustee may, on behalf of such Holders, vote for the
election of a trustee in bankruptcy or similar official.

SECTION 5.5 Trustee May Enforce Claims Without Possession of Securities.

      All rights of action and claims under this Indenture or the Securities may
be prosecuted and enforced by the Trustee without the possession of any of the
Securities or the production thereof in any proceeding relating thereto, and any
such proceeding instituted by the Trustee shall be brought in its own name as
trustee of an express trust, and any recovery of judgment shall, after provision
for the payment of the reasonable compensation, expenses, disbursements and
advances of the Trustee, its agents and counsel, be for the ratable benefit of
the Holders of the Securities in respect of which judgment has been recovered.

SECTION 5.6 Application of Money Collected.

      Subject to Article XIII, any money collected by the Trustee pursuant to
this Article V shall be applied in the following order, at the date or dates
fixed by the Trustee and, in case of the distribution of such money on account
of principal, premium, if any, or interest, upon presentation of the Securities
and the notation thereon of the payment if only partially paid and upon
surrender thereof if fully paid:

      FIRST: To the payment of all amounts due the Trustee under Section 6.7;

      SECOND: To the payment of the amounts then due and unpaid for principal
of, premium, if any, or interest (including Liquidated Damages, if any) on, the
Securities in respect of which or for

                                                                            -50-
<PAGE>
the benefit of which such money has been collected, ratably, without preference
or priority of any kind, according to the amounts due and payable on such
Securities for principal, premium, if any, and interest (including Liquidated
Damages, if any), respectively;

      THIRD: To such other Person or Persons, if any, to the extent entitled
thereto; and

      FOURTH: Any remaining amounts shall be repaid to the Company.

SECTION 5.7 Limitation on Suits.

      No Holder of any Security shall have any right to institute any
proceeding, judicial or otherwise, with respect to this Indenture, or for the
appointment of a receiver or trustee, or for any other remedy hereunder, unless:

      (1) such Holder has previously given written notice to the Trustee of an
Event of Default and such Event of Default is continuing at the time of such
institution;

      (2) the Holders of not less than 25% in principal amount of the
Outstanding Securities shall have made written request to the Trustee to
institute proceedings in respect of such Event of Default in its own name as
Trustee hereunder;

      (3) such Holder or Holders have offered to the Trustee, and if requested,
shall have provided, reasonable indemnity against the costs, expenses and
liabilities to be incurred in compliance with such request;

      (4) the Trustee for 60 days after its receipt of such notice under Section
5.7(1), request under 5.7(2) and offer of indemnity (or if requested, receipt of
indemnity) under Section 5.7(3) has failed to institute any such proceeding; and

      (5) no direction inconsistent with such written request has been given to
the Trustee during such 60 day period by the Holders of a majority in principal
amount of the Outstanding Securities, it being understood and intended that no
one or more of such Holders shall have any right in any manner whatever by
virtue of, or by availing of, any provision of this Indenture to affect, disturb
or prejudice the rights of any other of such Holders, or to obtain or seek to
obtain priority or preference over any other of such Holders or to enforce any
right under this Indenture, except in the manner herein provided and for the
equal and ratable benefit of all such Holders.

SECTION 5.8 Unconditional Right of Holders to Receive Principal, Premium and
            Interest and to Convert.

      Notwithstanding any other provision in this Indenture, but subject to the
provisions of Article XIII, the Holder of any Security shall have the right,
which is absolute and unconditional, to receive payment of the principal of,
premium, if any, and (subject to Section 3.7) interest (including Liquidated
Damages, if any) on such Security on the respective Stated Maturities expressed
in such Security (or, in the case of redemption or repurchase, on the Redemption
Date or Repurchase Date,

                                                                            -51-
<PAGE>
as the case may be), and to convert such Security in accordance with Article
XII, and to institute suit for the enforcement of any such payment and right to
convert, and such rights shall not be impaired without the consent of such
Holder.

SECTION 5.9 Restoration of Rights and Remedies.

      If the Trustee or any Holder of a Security has instituted any proceeding
to enforce any right or remedy under this Indenture and such proceeding has been
discontinued or abandoned for any reason, or has been determined adversely to
the Trustee or to such Holder, then and in every such case, subject to any
determination in such proceeding, the Company, the Trustee and the Holders of
Securities shall be restored severally and respectively to their former
positions hereunder and thereafter all rights and remedies of the Trustee and
such Holders shall continue as though no such proceeding had been instituted.

SECTION 5.10 Rights and Remedies Cumulative.

      Except as otherwise provided with respect to the replacement or payment of
mutilated, destroyed, lost or stolen Securities in the last paragraph of Section
3.6, no right or remedy herein conferred upon or reserved to the Trustee or to
the Holders of Securities is intended to be exclusive of any other right or
remedy, and every right and remedy shall, to the extent permitted by law, be
cumulative and in addition to every other right and remedy given hereunder or
now or hereafter existing at law or in equity or otherwise. The assertion or
employment of any right or remedy hereunder, or otherwise, shall not prevent the
concurrent assertion or employment of any other appropriate right or remedy.

SECTION 5.11 Delay or Omission Not Waiver.

      No delay or omission of the Trustee or of any Holder of any Security to
exercise any right or remedy accruing upon any Event of Default shall impair any
such right or remedy or constitute a waiver of any such Event of Default or any
acquiescence therein. Every right and remedy given by this Article V or by law
to the Trustee or to the Holders of Securities may be exercised from time to
time, and as often as may be deemed expedient, by the Trustee or (subject to the
limitations contained in this Indenture) by the Holders of Securities as the
case may be.

SECTION 5.12 Control by Holders of Securities.

      Subject to Section 6.3, the Holders of a majority in principal amount of
the Outstanding Securities shall have the right to direct the time, method and
place of conducting any proceeding for any remedy available to the Trustee or
exercising any trust or power conferred on the Trustee, provided that

      (1) such direction shall not be in conflict with any rule of law or with
this Indenture, and

      (2) the Trustee may take any other action deemed proper by the Trustee
which is not inconsistent with such direction, and

                                                                            -52-
<PAGE>
      (3) the Trustee need not take any action that might involve it in personal
liability or be unjustly prejudicial to the Holders of Securities not
consenting.

SECTION 5.13 Waiver of Past Defaults.

      The Holders, either (i) through the written consent of not less than a
majority in principal amount of the Outstanding Securities or (ii) by the
adoption of a resolution, at a meeting of Holders of the Outstanding Securities
at which a quorum is present, by the Holders of at least 66-2/3% in principal
amount of the Outstanding Securities represented at such meeting, may on behalf
of the Holders of all the Securities waive any past default hereunder and its
consequences, except a default (A) in the payment of the principal of, premium,
if any, or interest (including Liquidated Damages) on any Security, or (B) in
respect of a covenant or provision hereof which under Article VIII cannot be
modified or amended without the consent of the Holder of each Outstanding
Security affected.

      Upon any such waiver, such default shall cease to exist, and any Event of
Default arising therefrom shall be deemed to have been cured, for every purpose
of this Indenture; but no such waiver shall extend to any subsequent or other
default or impair any right consequent thereon.

SECTION 5.14 Undertaking for Costs.

      All parties to this Indenture agree, and each Holder of any Security by
his acceptance thereof shall be deemed to have agreed, that any court may in its
discretion require, in any suit for the enforcement of any right or remedy under
this Indenture, or any suit against the Trustee for any action taken, suffered
or omitted by it as Trustee, the filing by any party litigant in such suit of an
undertaking to pay the costs of such suit, and that such court may in its
discretion assess reasonable costs, including reasonable attorneys' fees,
against any party litigant in such suit, having due regard to the merits and
good faith of the claims or defenses made by such party litigant; but the
provisions of this Section 5.14 shall not apply to any suit instituted by the
Company, to any suit instituted by the Trustee, to any suit instituted by any
Holder, or group of Holders, holding in the aggregate more than 10% in principal
amount of the Outstanding Securities, or to any suit instituted by any Holder of
any Security for the enforcement of the payment of the principal of, premium, if
any, or interest on any Security on or after the respective Stated Maturity or
Maturities expressed in such Security (or, in the case of redemption or
repurchase, on or after the Redemption Date or Repurchase Date, as the case may
be) or for the enforcement of the right to convert any Security in accordance
with Article XII.

SECTION 5.15 Waiver of Stay, Usury or Extension Laws.

      The Company covenants (to the extent that it may lawfully do so) that it
will not at any time insist upon, or plead, or in any manner whatsoever claim or
take the benefit or advantage of, any stay, usury or extension law wherever
enacted, now or at any time hereafter in force, that may affect the covenants or
the performance of this Indenture; and the Company (to the extent that it may
lawfully do so) hereby expressly waives all benefit or advantage of any such law
and covenants that it will not hinder, delay or impede by reason of such law the
execution of any power herein granted

                                                                            -53-
<PAGE>
to the Trustee, but will suffer and permit the execution of every such power as
though no such law had been enacted.

                                   THE TRUSTEE

SECTION 6.1 Certain Duties and Responsibilities.

      (1) Except during the continuance of an Event of Default,

            (i) the Trustee undertakes to perform such duties and only such
duties as are specifically set forth in this Indenture, and no implied covenants
or obligations shall be read into this Indenture against the Trustee; and

            (ii) in the absence of bad faith on its part, the Trustee may
conclusively rely, as to the truth of the statements and the correctness of the
opinions expressed therein, upon certificates or opinions furnished to the
Trustee and conforming to the requirements of this Indenture, but in the case of
any such certificates or opinions which by any provision hereof are specifically
required to be furnished to the Trustee, the Trustee shall be under a duty to
examine the same to determine whether or not they conform to the requirements of
this Indenture, but not to verify the contents thereof.

      (2) In case an Event of Default has occurred and is continuing, the
Trustee shall exercise such of the rights and powers vested in it by this
Indenture, 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.

      (3) No provision of this Indenture shall be construed to relieve the
Trustee from liability for its own negligent action, its own negligent failure
to act, or its own willful misconduct, except that (i) this paragraph (3) shall
not be construed to limit the effect of paragraph

            (i) of this Section;

            (ii) the Trustee shall not be liable for any error of judgment made
in good faith by a Responsible Officer, unless it shall be proved that the
Trustee was negligent in ascertaining the pertinent facts;

            (iii) the Trustee shall not be liable with respect to any action
taken or omitted to be taken by it in good faith in accordance with the
direction of the Holders of a majority in principal amount of the Outstanding
Securities 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 Indenture; and

                                                                            -54-
<PAGE>
            (iv) no provision of this Indenture shall require the Trustee 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.

      (4) Whether or not therein expressly so provided, every provision of this
Indenture relating to the conduct or affecting the liability of or affording
protection to the Trustee shall be subject to the provisions of this Section.

SECTION 6.2 Notice of Defaults.

      Within 90 days after the occurrence of any default hereunder as to which
the Trustee has received written notice, the Trustee shall give to all Holders
of Securities, in the manner provided in Section 1.6, notice of such default,
unless such default shall have been cured or waived; provided, however, that,
except in the case of a default in the payment of the principal of, premium, if
any, or interest on any Security the Trustee shall be protected in withholding
such notice if and so long as the board of directors, the executive committee or
a trust committee of directors or Responsible Officers of the Trustee in good
faith determines that the withholding of such notice is in the interest of the
Holders; and provided, further, that in the case of any default of the character
specified in Section 5.1(4), no such notice to Holders of Securities shall be
given until at least 60 days after the occurrence thereof or, if applicable, the
cure period specified therein. For the purpose of this Section, the term
"default" means any event which is, or after notice or lapse of time or both
would become, an Event of Default.

SECTION 6.3 Certain Rights of Trustee.

      Subject to the provisions of Section 6.1:

      (1) the Trustee may rely, and shall be protected in acting or refraining
from acting, upon any resolution, Officers' Certificate, other certificate,
statement, instrument, opinion, report, notice, request, direction, consent,
order, bond, debenture, note, coupon, other evidence of indebtedness or other
paper or document (collectively, the "Documents") believed by it to be genuine
and to have been signed or presented by the proper party or parties, and the
Trustee need not investigate any fact or matter stated in such Documents;

sufficiently evidenced by a Company Request or Company Order and any resolution

deem it desirable that a matter be proved or established prior to taking,

be the one specifically prescribed) may, in the absence of bad faith on its
part, request and rely upon an Officers' Certificate or Opinion of Counsel;

                                                                            -55-
<PAGE>
      (4) the Trustee may consult with counsel of its selection and the advice
of such counsel or any Opinion of Counsel shall be full and complete
authorization and protection in respect of any action taken, suffered or omitted
by it hereunder in good faith and in reliance thereon;

      (5) the Trustee shall be under no obligation to exercise any of the rights
or powers vested in it by this Indenture at the request or direction of any of
the Holders of Securities pursuant to this Indenture, unless such Holders shall
have offered, and, if requested by the Trustee, delivered to the Trustee
reasonable security or indemnity against the costs, expenses and liabilities
which might be incurred by it in compliance with such request or direction;

      (6) 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, direction, consent, order, bond, debenture,
note, coupon, other evidence of indebtedness or other paper or document, but the
Trustee may make such further inquiry or investigation into such facts or
matters as it may see fit, and, if the Trustee shall determine to make such
further inquiry or investigation, it shall be entitled to examine the books,
records and premises of the Company, personally or by agent or attorney; and

negligence on the part of any agent or attorney appointed with due care by it
hereunder.

SECTION 6.4 Not Responsible for Recitals or Issuance of Securities.

      The recitals contained herein and in the Securities (except the Trustee's
certificates of authentication) shall be taken as the statements of the Company,
and the Trustee assumes no responsibility for their correctness. The Trustee
makes no representations as to the validity or sufficiency of this Indenture, of
the Securities or of the Common Stock issuable upon the conversion of the
Securities. The Trustee shall not be accountable for the use or application by
the Company of Securities or the proceeds thereof.

      The Trustee, any Authenticating Agent, any Paying Agent, any Conversion
Agent or any other agent of the Company or the Trustee, in its individual or any
other capacity, may become the owner or pledgee of Securities and may otherwise
deal with the Company with the same rights it would have if it were not Trustee,
Authenticating Agent, Paying Agent, Conversion Agent or such other agent.

      The Trustee may become and act as trustee under other indentures under
which other securities, or certificates of interest or participation in other
securities, of the Company are outstanding in the same manner as if it were not
Trustee hereunder.

                                                                            -56-

SECTION 6.6 Money Held in Trust.

      Money held by the Trustee in trust hereunder need not be segregated from
other funds except to the extent required by law. The Trustee shall be under no
liability for interest on any money received by it hereunder except as otherwise
agreed in writing with the Company.

SECTION 6.7 Compensation and Reimbursement.

      The Company agrees:

      (1) to pay to the Trustee from time to time such reasonable compensation
as the Company and the Trustee shall from time to time agree in writing for its
acceptance of this Indenture and for all services rendered by it hereunder

the compensation of a trustee of an express trust);

      (2) except as otherwise expressly provided herein, to reimburse the
Trustee upon its request for all reasonable expenses, disbursements and advances
incurred or made by the Trustee (including costs and expenses of enforcing this
Indenture and defending itself against any claim (whether asserted by the
Company, any Holder of Securities or any other Person) or liability in
connection with the exercise of any of its powers or duties hereunder) in

except any such expense, disbursement or advance as may be attributable to its
negligence or bad faith; and

      (3) to indemnify the Trustee (and its directors, officers, employees and
agents) for, and to hold it harmless against, any loss, liability or expense
incurred without negligence or bad faith on its part, arising out of or in

SECTION 6.9 Resignation and Removal; Appointment of Successor.

      (1) No resignation or removal of the Trustee and no appointment of a
successor Trustee pursuant to this Article shall become effective until the
acceptance of appointment by the successor Trustee in accordance with the
applicable requirements of Section 6.10.

      (2) The Trustee may resign at any time by giving written notice thereof to
the Company. If the instrument of acceptance by a successor Trustee required by

court of competent jurisdiction for the appointment of a successor Trustee.

      (3) The Trustee may be removed at any time by an Act of the Holders of a

shall be appointed or any public officer shall take charge or control of the
Trustee or of its property or affairs for the purpose of rehabilitation,
conservation or liquidation,

Trustee, or (ii) subject to Section 5.14, any Holder of a Security who has been

or if a vacancy shall occur in the office of Trustee for any cause, the Company,
by a Board Resolution, shall promptly appoint a successor Trustee and shall

within one year after such resignation, removal or incapability, or the
occurrence of such vacancy, a successor Trustee shall be appointed by Act of the
Holders of a majority in principal amount of the Outstanding Securities
delivered to the Company and the retiring Trustee, the successor Trustee so
appointed shall, forthwith upon its acceptance of such appointment in accordance
with the applicable requirements of Section 6.10, become the successor Trustee
and supersede the successor Trustee appointed by the Company. If no successor
Trustee shall have been so appointed by the Company or the Holders of Securities
and accepted appointment in the manner required by this Section and Section

or conveyance, shall become vested with all the rights, powers, trusts and
duties of the retiring Trustee; but, on the request of the Company or the
successor Trustee, such retiring Trustee shall, upon payment of its charges,
execute and deliver an instrument transferring to such successor Trustee all the
rights, powers and trusts of the retiring Trustee and shall duly assign,
transfer and deliver to such successor Trustee all property and money held by
such retiring Trustee hereunder. Upon request of any such successor Trustee, the
Company shall execute any and all instruments to more fully and with more
certainty vest in and confirm to such successor Trustee all such rights, powers
and trusts.

      No successor Trustee shall accept its appointment unless at the time of
such acceptance such successor Trustee shall be eligible under this Article.

business of the Trustee (including the trust created by this Indenture), shall

<PAGE>
Trustee hereunder, provided such corporation shall be otherwise eligible under
this Article, without the execution or filing of any paper or any further act on
the part of any of the parties hereto. In case any Securities shall have been
authenticated, but not delivered, by the Trustee then in office, any successor
by merger, conversion or consolidation to such authenticating Trustee may adopt
such authentication and deliver the Securities so authenticated with the same
effect as if such successor Trustee had itself authenticated such Securities.

SECTION 6.12 Authenticating Agents.

      The Trustee may, with the consent of the Company, appoint an
"Authenticating Agent" or Agents acceptable to the Company with respect to the
Securities, which Authenticating Agent shall be authorized to act on behalf of
the Trustee to authenticate Securities issued upon exchange or substitution
pursuant to this Indenture.

      Securities authenticated by an Authenticating Agent shall be entitled to
the benefits of this Indenture and shall be valid and obligatory for all
purposes as if authenticated by the Trustee hereunder, and every reference in
this Indenture to the authentication and delivery of Securities by the Trustee
or the Trustee's certificate of authentication shall be deemed to include
authentication and delivery on behalf of the Trustee by an Authenticating Agent
and a certificate of authentication executed on behalf of the Trustee by an
Authenticating Agent. Each Authenticating Agent shall be subject to acceptance
by the Company and shall at all times be a corporation organized and doing
business under the laws of the United States of America, any State thereof or
the District of Columbia, authorized under such laws to act as Authenticating
Agent and subject to supervision or examination by government or other fiscal
authority. If at any time an Authenticating Agent shall cease to be eligible in
accordance with the provisions of this Section 6.12, such Authenticating Agent
shall resign immediately in the manner and with the effect specified in this
Section 6.12.

      Any corporation into which an Authenticating Agent may be merged or
converted or with which it may be consolidated, or any corporation resulting
from any merger, conversion or consolidation to which such Authenticating Agent
shall be a party, or any corporation succeeding to all or substantially all the
corporate agency or corporate trust business of an Authenticating Agent
(including the authenticating agency contemplated by this Indenture), shall
continue to be an Authenticating Agent, provided such corporation shall be
otherwise eligible under this Section 6.12, without the execution or filing of
any paper or any further act on the part of the Trustee or the Authenticating
Agent.

      An Authenticating Agent may resign at any time by giving written notice
thereof to the Trustee and to the Company. The Trustee may at any time terminate
the agency of an Authenticating Agent by giving written notice thereof to such
Authenticating Agent and to the Company. Upon receiving such a notice of
resignation or upon such a termination, or in case at any time such
Authenticating Agent shall cease to be eligible in accordance with the
provisions of this Section 6.12, the Trustee may appoint a successor
Authenticating Agent which shall be subject to acceptance by the Company. Any
successor Authenticating Agent upon acceptance of its appointment hereunder
shall become vested with all the rights, powers and duties of its predecessor

                                                                            -60-

hereunder, with like effect as if originally named as an Authenticating Agent.
No successor Authenticating Agent shall be appointed unless eligible under the
provisions of this Section 6.12.

         The Company agrees to pay to each Authenticating Agent from time to
time reasonable compensation for its services under this Section 6.12.

         If an Authenticating Agent is appointed with respect to the Securities
pursuant to this Section 6.12, the Securities may have endorsed thereon, in
addition to or in lieu of the Trustee's certification of authentication, an
alternative certificate of authentication in the following form:

         This is one of the Securities referred to in the within-mentioned
Indenture.

original reports of the inspectors of votes on any vote by ballot taken thereat
and affidavits by one or more Persons having knowledge of the facts setting

the meeting and one such copy shall be delivered to the Company and another to
the Trustee to be preserved by the Trustee, the latter to have attached thereto
the ballots voted at the meeting. Any record so signed and verified shall be
conclusive evidence of the matters therein stated.

         The Company will cause each Paying Agent other than the Trustee to
execute and deliver to the Trustee an instrument in which such Paying Agent
shall agree with the Trustee, subject to the provisions of this Section, that
such Paying Agent will:

         (1) hold all sums held by it for the payment of the principal of,
premium, if any, or interest on Securities for the benefit of the Persons

satisfaction and discharge of this Indenture or for any other purpose, pay, or
by Company Order direct any Paying Agent to pay, to the Trustee all sums held in
trust by the Company or such Paying Agent, such sums to be held by the Trustee
upon the same trusts as those upon which such sums were held by the Company or
such Paying Agent; and, upon such payment by any Paying Agent to the Trustee,

principal, premium, if any, or interest has become due and payable shall be paid
to the Company on Company Request, or (if then held by the Company) shall be
discharged from such trust; and the Holder of such Security shall thereafter, as
an unsecured general creditor, look only to the Company for payment thereof, and
all liability of the Trustee or such Paying Agent with respect to such trust
money, and all liability of the Company as trustee thereof, shall thereupon

things necessary to preserve and keep in full force and effect its existence,
rights (charter and statutory) and franchises; provided, however, that the
Company shall not be required to preserve any such right or franchise if the

disadvantageous in any material respect to the Holders.

SECTION 10.5      Maintenance of Properties.

be necessary so that the business carried on in connection therewith may be
properly and advantageously conducted at all times; provided, however, that
nothing in this Section shall prevent the Company from discontinuing the

business of any Subsidiary and not disadvantageous in any material respect to
the Holders.

case of clauses (i) and (ii), the Company shall not be required to pay or
discharge or cause to be paid or discharged any such tax, assessment, charge or
claim (A) if the failure to do so will not, in the aggregate, have a material
adverse impact on the Company, or (B) if the amount, applicability or validity
is being contested in good faith by appropriate proceedings.

SECTION 10.7      Registration and Listing.

         The Company (i) will effect all registrations with, and obtain all

<PAGE>
shares of Common Stock issued upon conversion of Restricted Securities, or to a
prospective purchaser of any such security designated by any such Holder or
holder, as the case may be, to the extent required to permit compliance by such
Holder or holder with Rule 144A under the Securities Act (or any successor
provision thereto) in connection with the resale of any such security; provided,
however, that the Company shall not be required to furnish such information in
connection with any request made on or after the date which is two years from
the later of (i) the Issue Date, (ii) the date such a security (or any such
predecessor security) was last acquired from the Company or (iii) the date such
a security (or any such predecessor security) was last acquired from an
"affiliate" of the Company within the meaning of Rule 144 under the Securities
Act (or any successor provision thereto). "Rule 144A Information" shall be such
information as is specified pursuant to Rule 144A(d)(4) under the Securities Act

SECTION 10.10     Resale of Certain Securities.

         During the period beginning on the last date of original issuance of
the Securities and ending on the date that is two years from such date (or such
shortened period under Rule 144(k) under the Securities Act or any successor
rule), the Company will not, and will not permit any of its subsidiaries or
other "affiliates" (as defined under Rule 144 under the Securities Act or any
successor provision thereto) to, resell (i) any Securities which constitute
"restricted securities" under Rule 144 or (ii) any securities into which the
Securities have been converted under this Indenture which constitute "restricted
securities" under Rule 144, that in either case have been reacquired by any of
them. The Trustee shall have no responsibility in respect of the Company's
performance of its agreement in the preceding sentence.

SECTION 10.11     Registration Rights.

      (1) The Company agrees that the Holders from time to time of Registrable
Securities (as defined below) are entitled to the benefits of a Registration
Rights Agreement, dated as of June 13, 2003 (the "Registration Rights
Agreement"), executed by the Company. Pursuant to the Registration Rights
Agreement, the Company has agreed for the benefit of the holders from time to
time of the Registrable Securities that it will, at its expense, (i) within 90
days after the Issue Date, file a shelf registration statement (the "Shelf
Registration Statement") with the Commission with respect to resales of the
Registrable Securities, (ii) use its reasonable efforts to cause such Shelf
Registration Statement to be declared effective by the Commission within 180
days after the Issue Date, provided, however that the Company may, upon written
notice to all the Holders, postpone having the Shelf Registration Statement
declared effective if the Company possesses material non-public information, the
disclosure of which would have a material adverse effect on the Company and its
subsidiaries taken as a whole and (iii) use its reasonable efforts to maintain
such Shelf Registration Statement effective under the Securities Act until the
second annual anniversary of the Issue Date or, if earlier, until there are no
outstanding Registrable Securities (the "Effectiveness Period"). The Company
will be permitted to suspend the use of the prospectus which is a part of the
Shelf Registration Statement during certain periods of time as provided in the
Registration Rights Agreement.

                                                                            -72-
<PAGE>
         (2) If (i) on or prior to 90 days following the Issue Date, a Shelf
Registration Statement has not been filed with the Commission, or (ii) on or
prior to the 180th day following the Issue Date, such Shelf Registration
Statement is not declared effective (each, a "Registration Default"), additional
interest ("Liquidated Damages") will accrue on the Registrable Securities from
and including the day following such Registration Default to but excluding the
day on which such Registration Default has been cured. Liquidated Damages will
be paid semi-annually in arrears, with the first semi-annual payment due on the
first Interest Payment Date in respect of the Registrable Securities following
the date on which such Liquidated Damages begin to accrue, and will accrue at a
rate per annum equal to an additional one-quarter of one percent (0.25%) of the
principal amount of the Registrable Securities to and including the 90th day
following such Registration Default and at a rate per annum equal to one-half of
one percent (0.50%) thereof from and after the 91st day following such
Registration Default. Pursuant to the Registration Rights Agreement, in the
event that the Shelf Registration Statement ceases to be effective (or the
Holders of Registrable Securities are otherwise prevented or restricted by the
Company from effecting sales pursuant thereto) (an "Effective Failure") during
the Effectiveness Period for more than 45 days, whether or not consecutive,
during any 90-day period or for more than 90 days, whether or not consecutive,
during any 365-day period, then the interest rate borne by the Registrable
Securities shall increase by an additional one-quarter of one percent (0.25%)
per annum from and including the 46th day of the applicable 90-day period and
shall increase by an additional one-half of one percent (0.50%) per annum from
the 91st day of the applicable 365-day period until the earlier of (A) such time
as the Effective Failure is cured or (B) the Effectiveness Period expires.
Liquidated Damages will accrue (1) with respect to a Restricted Security at the
rates set forth above, as applicable, on the principal amount of the Restricted
Securities and (2) in respect of the Common Sock issued upon conversion of the
Restricted Securities, at the rates set forth above, as applicable, applied to
the Conversion Price at that time. In no event shall the Company be required to
pay Liquidated Damages in excess of the applicable maximum amount of one-half of
one percent (0.5%) set forth above.

         (3) Whenever in this Indenture there is mentioned, in any context, the
payment of interest on, or in respect of, any Security, such mention shall be
deemed to include mention of the payment of Liquidated Damages provided for in
this Section to the extent that, in such context, Liquidated Damages are, were
or would be payable in respect thereof pursuant to the provisions of this
Section and express mention of the payment of Liquidated Damages (if applicable)
in any provisions hereof shall not be construed as excluding Liquidated Damages
in those provisions hereof where such express mention is not made.

         (4) "Registrable Securities" means all or any portion of the Restricted
Securities issued from time to time under this Indenture and the shares of
Common Stock issuable upon conversion or repurchase of such Restricted
Securities, except any such Restricted Security or share of Common Stock
issuable upon conversion or repurchase thereof that (i) has been effectively
registered under the Securities Act and sold in a manner contemplated by the
Shelf Registration Statement, (ii) has been transferred in compliance with Rule
144 under the Securities Act (or any successor provision thereto) or is
transferable pursuant to paragraph (k) of such Rule 144 (or any successor
provision thereto) or (iii) otherwise has been transferred and a new Security or
share of Common Stock not

                                      -73-
<PAGE>
subject to transfer restrictions under the Securities Act has been delivered by
or on behalf of the Company in accordance with Section 3.5 of this Indenture.

         (5) If a Security, or the shares of Common Stock issuable upon
conversion of a Security, is a Registrable Security, and the Holder thereof
elects to sell such Registrable Security pursuant to the Shelf Registration
Statement then, by its acceptance thereof, the Holder of such Registrable
Security will have agreed to be bound by the terms of the Registration Rights
Agreement relating to the Registrable Securities which are the subject of such
election.

         (6) For the purposes of the Registration Rights Agreement, the term
"Holder" includes any Person that has a beneficial interest in any Restricted
Global Security or any beneficial interest in a global security representing
shares of Common Stock issuable upon conversion of a Security.

         (7) If Liquidated Damages are payable under the Registration Rights
Agreement, the Company shall deliver to the Trustee a certificate to that effect
stating (i) the amount of Liquidated Damages that is payable and (ii) the date
on which Liquidated Damages are payable. Unless and until a Responsible Officer
of the Trustee receives at the Corporate Trust Office such a certificate, the
Trustee may assume without inquiry that no Liquidated Damages are payable. If
Liquidated Damages have been paid by the Company directly to the persons
entitled to them, the Company shall deliver to the Trustee a certificate setting
forth the particulars of such payment.

SECTION 10.12      Waiver of Certain Covenants.

         The Company may omit in any particular instance to comply with any
covenant or condition set forth in Sections 10.4 (other than with respect to the
existence of the Company (subject to Article VII)), 10.5 and 10.6, inclusive
(other than a covenant or condition which under Article VIII cannot be modified
or amended without the consent of the Holder of each Outstanding Security
affected), if before the time for such compliance the Holders shall, through (i)
the written consent of not less than a majority in principal amount of the
Outstanding Securities or (ii) the adoption of a resolution at a meeting of
Holders of the Outstanding Securities at which a quorum is present by the
Holders of not less than 66-2/3% in principal amount of the Outstanding
Securities represented at such meeting, either waive such compliance in such
instance or generally waive compliance with such covenant or condition, but no
such waiver shall extend to or affect such covenant or condition except to the
extent so expressly waived, and, until such waiver shall become effective, the
obligations of the Company and the duties of the Trustee or any Paying or
Conversion Agent in respect of any such covenant or condition shall remain in
full force and effect.

                                   ARTICLE XI
                            REDEMPTION OF SECURITIES

SECTION 11.1      Right of Redemption.

         The Securities may be redeemed in accordance with the provisions of the
form of Securities set forth in Section 2.2.

                                                                            -74-
<PAGE>
SECTION 11.2      Applicability of Article.

         Redemption of Securities at the election of the Company or otherwise,
as permitted or required by any provision of the Securities or this Indenture,
shall be made in accordance with such provision and this Article XI.

SECTION 11.3      Election to Redeem; Notice to Trustee.

         The election of the Company to redeem any Securities shall be evidenced
by a Board Resolution. Subject to Section 11.5, in case of any redemption at the
election of the Company of any of the Securities, the Company shall, at least 45
days prior to the Redemption Date fixed by the Company (unless a shorter notice
shall be satisfactory to the Trustee), notify the Trustee in writing of such
Redemption Date.

SECTION 11.4      Selection by Trustee of Securities to Be Redeemed.

         If less than all the Securities are to be redeemed, the particular
Securities to be redeemed shall be selected by the Trustee within five Business
Days after it receives the notice described in 11.3, from the Outstanding
Securities not previously called for redemption, by lot or by such other method
as the Trustee may deem fair and appropriate.

         If any Security selected for partial redemption is converted in part
before termination of the conversion right with respect to the portion of the
Security so selected, the converted portion of such Security shall be deemed (so
far as may be) to be the portion selected for redemption. Securities which have
been converted during a selection of Securities to be redeemed may be treated by
the Trustee as Outstanding for the purpose of such selection. The Trustee shall
promptly notify the Company and each Security Registrar in writing of the
securities selected for redemption and, in the case of any Securities selected
for partial redemption, the principal amount thereof to be redeemed.

         For all purposes of this Indenture, unless the context otherwise
requires, all provisions relating to the redemption of Securities shall relate,
in the case of any Securities redeemed or to be redeemed only in part, to the
portion of the principal amount of such Securities which has been or is to be
redeemed.

SECTION 11.5      Notice of Redemption.

         Notice of redemption shall be given in the manner provided in Section
1.6 to the Holders of Securities to be redeemed not less than 30 nor more than
60 days prior to the Redemption Date, and such notice shall be irrevocable. The
Company shall, concurrently with the giving of such notice, publish a Press
Release including the information required to be included in such notice of
redemption hereunder.

         All notices of redemption shall state:

         (1) the Redemption Date,

                                                                            -75-
<PAGE>
         (2) the Redemption Price, and accrued interest (including Liquidated
Damages, if any), if any, to, but excluding, the Redemption Date,

         (3) if less than all Outstanding Securities are to be redeemed, the
aggregate principal amount of Securities to be redeemed and the aggregate
principal amount of Securities which will be outstanding after such partial
redemption,

         (4) that on the Redemption Date the Redemption Price, and accrued but
unpaid interest (including Liquidated Damages, if any), if any, to, but
excluding, the Redemption Date, will become due and payable upon each such
Security to be redeemed, and that interest thereon shall cease to accrue on and
after said date,

         (5) the Conversion Rate, the date on which the right to convert the
Securities to be redeemed will terminate and the places where such Securities
may be surrendered for conversion, and

         (6) the place or places where such Securities are to be surrendered for
payment of the Redemption Price and accrued interest (including Liquidated
Damages, if any), if any, to, but excluding, the Redemption Date.

         In case of a partial redemption, the notice shall specify the serial
and CUSIP numbers (if any) and the portions thereof called for redemption and
that transfers and exchanges may occur on or prior to the Redemption Date.

         Notice of redemption of Securities to be redeemed at the election of
the Company shall be given by the Company or, at the Company's written request,
by the Trustee in the name of and at the expense of the Company. Notice of
redemption of Securities to be redeemed at the election of the Company received
by the Trustee shall be given by the Trustee to each Paying Agent in the name of
and at the expense of the Company.

SECTION 11.6      Deposit of Redemption Price.

         On or prior to the Redemption Date, the Company shall deposit with the
Trustee (or, if the Company is acting as its own Paying Agent, segregate and
hold in trust as provided in Section 10.3) an amount of money (which shall be in
immediately available funds on such Redemption Date) sufficient to pay the
Redemption Price of, and (except if the Redemption Date shall be an Interest
Payment Date) accrued interest (including Liquidated Damages, if any) to the
Redemption Date on, all the Securities which are to be redeemed on that date
other than any Securities called for redemption on that date which have been
converted prior to the date of such deposit.

         If any Security called for redemption is converted, any money deposited
with the Trustee or so segregated and held in trust for the redemption of such
Security shall (subject to any right of the Holder of such Security or any
Predecessor Security to receive interest as provided in the last paragraph of
Section 3.7) be paid to the Company on Company Request or, if then held by the
Company, shall be discharged from such trust.

                                                                            -76-
<PAGE>
SECTION 11.7      Securities Payable on Redemption Date.

         Notice of redemption having been given as aforesaid, the Securities so
to be redeemed shall, on the Redemption Date, become due and payable at the
Redemption Price therein specified and from and after such date (unless the
Company shall default in the payment of the Redemption Price, including accrued
interest) such Securities shall cease to bear interest. Upon surrender of any
Security for redemption in accordance with said notice such Security shall be
paid by the Company at the Redemption Price together with accrued and unpaid
interest (including Liquidated Damages, if any) to the Redemption Date;
provided, however, that installments of interest on Securities whose Stated
Maturity is on or prior to the Redemption Date shall be payable to the Holders
of such Securities, or one or more Predecessor Securities, registered as such on
the relevant Record Date according to their terms and the provisions of Section
3.7.

         If any Security called for redemption shall not be so paid upon
surrender thereof for redemption, the principal amount of, premium, if any, and,
to the extent permitted by applicable law, accrued interest on such Security
shall, until paid, bear interest from the Redemption Date at a rate of 4.25% per
annum and such Security shall remain convertible until the Redemption Price of
such Security (or portion thereof, as the case may be) shall have been paid or
duly provided for.

         Any Security that is to be redeemed only in part shall be surrendered
at the Corporate Trust Office or an office or agency of the Company designated
for that purpose pursuant to Section 10.2 (with, if the Company or the Trustee
so requires, due endorsement by, or a written instrument of transfer in form
satisfactory to the Company and the Trustee duly executed by, the Holder thereof
or his attorney duly authorized in writing), and the Company shall execute, and
the Trustee shall authenticate and make available for delivery to the Holder of
such Security without service charge, a new Security or Securities, of any
authorized denomination as requested by such Holder, in aggregate principal
amount equal to and in exchange for the unredeemed portion of the principal of
the Security so surrendered.

SECTION 11.8      Conversion Arrangement on Call for Redemption.

         In connection with any redemption of Securities, the Company may
arrange for the purchase and conversion of any Securities by an agreement with
one or more investment bankers or other purchasers (the "Purchasers") to
purchase such securities by paying to the Trustee in trust for the Holders, on
or before the Redemption Date, an amount not less than the applicable Redemption
Price, together with interest accrued to the Redemption Date, of such
Securities. Notwithstanding anything to the contrary contained in this Article
XI, the obligation of the Company to pay the Redemption Price, together with
interest accrued to the Redemption Date, shall be deemed to be satisfied and
discharged to the extent such amount is so paid by such Purchasers. If such an
agreement is entered into (a copy of which shall be filed with the Trustee prior
to the close of business on the Business Day immediately prior to the Redemption
Date), any Securities called for redemption that are not duly surrendered for
conversion by the Holders thereof may, at the option of the Company, be deemed,
to the fullest extent permitted by law, and consistent with any agreement or
agreements with such Purchasers, to be acquired by such Purchasers from such
Holders and (notwithstanding anything to the contrary contained in Article XII)
surrendered by such Purchasers

                                                                            -77-
<PAGE>
for conversion, all as of immediately prior to the close of business on the
Redemption Date (and the right to convert any such Securities shall be extended
through such time), subject to payment of the above amount as aforesaid. At the
direction of the Company, the Trustee shall hold and dispose of any such amount
paid to it by the Purchasers to the Holders in the same manner as it would
monies deposited with it by the Company for the redemption of Securities.
Without the Trustee's prior written consent, no arrangement between the Company
and such Purchasers for the purchase and conversion of any Securities shall
increase or otherwise affect any of the powers, duties, responsibilities or
obligations of the Trustee as set forth in this Indenture, and the Company
agrees to indemnify the Trustee from, and hold it harmless against, any loss,
liability or expense arising out of or in connection with any such arrangement
for the purchase and conversion of any Securities between the Company and such
Purchasers, including the costs and expenses, including reasonable legal fees,
incurred by the Trustee in the defense of any claim or liability arising out of
or in connection with the exercise or performance of any of its powers, duties,
responsibilities or obligations under this Indenture.

                                  ARTICLE XII
                            CONVERSION OF SECURITIES

SECTION 12.1      Conversion Privilege and Conversion Rate.

         Subject to and upon compliance with the provisions of this Article, at
the option of the Holder thereof, any Security may be converted into fully paid
and nonassessable shares (calculated as to each conversion to the nearest
1/100th of a share) of Common Stock of the Company at the Conversion Rate,
determined as hereinafter provided, in effect at the time of conversion. Such
conversion right shall commence on the Issue Date and expire at the close of
business on the date of Maturity, subject, in the case of conversion of any
Global Security, to any Applicable Procedures. In case a Security or portion
thereof is called for redemption at the election of the Company or the Holder
thereof exercises his right to require the Company to repurchase the Security,
such conversion right in respect of the Security, or portion thereof so called,
shall expire at the close of business on the Business Day immediately preceding
the Redemption Date or the Repurchase Date, as the case may be, unless the
Company defaults in making the payment due upon redemption or repurchase, as the
case may be, in which case the conversion right will terminate at the close of
business on the date such default is cured (in each case subject as aforesaid to
any Applicable Procedures with respect to any Global Security).

         The rate at which shares of Common Stock shall be delivered upon
conversion (herein called the "Conversion Rate") shall be initially equal to the
quotient obtained by dividing 1000 by the Initial Conversion Price for each
U.S.$1,000 principal amount of Securities. The Conversion Rate shall be adjusted
in certain instances as provided in this Article XII.

SECTION 12.2      Exercise of Conversion Privilege.

         In order to exercise the conversion privilege, the Holder of any
Security to be converted shall surrender such Security, duly endorsed in blank,
at any office or agency of the Company maintained for that purpose pursuant to
Section 10.2, accompanied by a duly signed conversion notice

                                                                            -78-
<PAGE>
substantially in the form set forth in Section 2.4 stating that the Holder
elects to convert such Security or, if less than the entire principal amount
thereof is to be converted, the portion thereof to be converted. Each Security
surrendered for conversion (in whole or in part) during the Record Date Period
shall (except in the case of any Security or portion thereof which has been
called for redemption or if a Change in Control has occurred and an offer to
repurchase the Securities is pending) be accompanied by payment in New York
Clearing House funds or other funds acceptable to the Company of an amount equal
to the interest payable on such Interest Payment Date on the principal amount of
such Security (or part thereof, as the case may be) being surrendered for
conversion. The interest so payable on such Interest Payment Date with respect
to any Security (or portion thereof, if applicable) that is surrendered for
conversion during the Record Date Period shall be paid to the Holder of such
Security as of such Regular Record Date in an amount equal to the interest that
would have been payable on such Security if such Security had been converted as
of the close of business on such Interest Payment Date. Interest payable on any
Interest Payment Date in respect of any Security surrendered for conversion on
or after such Interest Payment Date shall be paid to the Holder of such Security
as of the Regular Record Date next preceding such Interest Payment Date,
notwithstanding the exercise of the right of conversion. Except as provided in
this paragraph and subject to the last paragraph of Section 3.7, no cash payment
or adjustment shall be made upon any conversion on account of any interest
accrued from the Interest Payment Date next preceding the conversion date, in
respect of any Security (or part thereof, as the case may be) surrendered for
conversion, or on account of any dividends on the Common Stock issued upon
conversion. The Company's delivery to the Holder of the number of shares of
Common Stock (and cash in lieu of fractions thereof, as provided in this
Indenture) into which a Security is convertible will be deemed to satisfy the
Company's obligation to pay the principal amount of the Security.

         Securities shall be deemed to have been converted immediately prior to
the close of business on the day of surrender of such Securities for conversion
in accordance with the foregoing provisions, and at such time the rights of the
Holders of such Securities as Holders shall cease, and the Person or Persons
entitled to receive the Common Stock issuable upon conversion shall be treated
for all purposes as the record holder or holders of such Common Stock at such
time. As promptly as practicable on or after the conversion date, the Company
shall issue and deliver to the Trustee, for delivery to the Holder, a
certificate or certificates for the number of full shares of Common Stock
issuable upon conversion, together with payment in lieu of any fraction of a
share, as provided in Section 12.3.

         All shares of Common Stock delivered upon such conversion of Restricted
Securities shall bear restrictive legends substantially in the form of the
legends required to be set forth on the Restricted Securities pursuant to
Section 3.5 and shall be subject to the restrictions on transfer provided in
such legends. Neither the Trustee nor any agent maintained for the purpose of
such conversion shall have any responsibility for the inclusion or content of
any such restrictive legends on such Common Stock; provided, however, that the
Trustee or any agent maintained for the purpose of such conversion shall have
provided, to the Company or to the Company's transfer agent for such Common
Stock, prior to or concurrently with a request to the Company to deliver such
Common Stock, written notice that the Securities delivered for conversion are
Restricted Securities.

                                                                            -79-
<PAGE>
         In the case of any Security which is converted in part only, upon such
conversion the Company shall execute and the Trustee shall authenticate and
deliver to the Holder thereof, at the expense of the Company, a new Security or
Securities of authorized denominations in an aggregate principal amount equal to
the unconverted portion of the principal amount of such Security. A Security may
be converted in part, but only if the principal amount of such Security to be
converted is any integral multiple of U.S.$1,000 and the principal amount of
such security to remain Outstanding after such conversion is equal to U.S.$1,000
or any integral multiple of $1,000 in excess thereof.

         If shares of Common Stock to be issued upon conversion of a Restricted
Security, or Securities to be issued upon conversion of a Restricted Security in
part only, are to be registered in a name other than that of the beneficial
owner of such Restricted Security, then such Holder must deliver to the
Conversion Agent a Surrender Certificate, dated the date of surrender of such
Restricted Security and signed by such beneficial owner, as to compliance with
the restrictions on transfer applicable to such Restricted Security. Neither the
Trustee nor any Conversion Agent, Registrar or Transfer Agent shall be required
to register in a name other than that of the beneficial owner, shares of Common
Stock or Securities issued upon conversion of any such Restricted Security not
so accompanied by a properly completed Surrender Certificate.

SECTION 12.3      Fractions of Shares.

         No fractional shares of Common Stock shall be issued upon conversion of
any Security or Securities. If more than one Security shall be surrendered for
conversion at one time by the same Holder, the number of full shares which shall
be issuable upon conversion thereof shall be computed on the basis of the
aggregate principal amount of the Securities (or specified portions thereof) so
surrendered. Instead of any fractional share of Common Stock that would
otherwise be issuable upon conversion of any Security or Securities (or
specified portions thereof), the Company shall calculate and pay a cash
adjustment in respect of such fraction (calculated to the nearest 1/100th of a
share) in an amount equal to the same fraction of the Closing Price Per Share on
the last Trading Day prior to the day of conversion.

SECTION 12.4      Adjustment of Conversion Rate.

         The Conversion Rate shall be subject to adjustments from time to time
as follows:

         (1) In case the Company shall pay or make a dividend or other
distribution on shares of Common Stock payable in shares of Common Stock, the
Conversion Rate in effect at the opening of business on the day following the
date fixed for the determination of shareholders entitled to receive such
dividend or other distribution shall be increased by dividing such Conversion
Rate by a fraction of which the numerator shall be the number of shares of
Common Stock outstanding at the close of business on the date fixed for such
determination and the denominator shall be the sum of such number of shares and
the total number of shares constituting such dividend or other distribution,
such increase to become effective immediately after the opening of business on
the day following the date fixed for such determination. If, after any such date
fixed for determination, any dividend or distribution is not in fact paid, the
Conversion Rate shall be immediately readjusted, effective as of

                                                                            -80-
<PAGE>
the date the Board of Directors determines not to pay such dividend or
distribution, to the Conversion Rate that would have been in effect if such
determination date had not been fixed. For the purposes of this paragraph (1),
the number of shares of Common Stock at any time outstanding shall not include
shares held in the treasury of the Company but shall include shares issuable in
respect of scrip certificates issued in lieu of fractions of shares of Common
Stock. The Company will not pay any dividend or make any distribution on shares
of Common Stock held in the treasury of the Company.

         (2) In case the Company shall issue rights, options or warrants to all
holders of its Common Stock (other than rights issued pursuant to the Rights
Plan (as defined in paragraph (13) of this Section 12.4)) entitling them to
subscribe for or purchase shares of Common Stock at a price per share less than
the current market price per share (determined as provided in paragraph (8) of
this Section 12.4) of the Common Stock on the date fixed for the determination
of stockholders entitled to receive such rights, options or warrants (other than
any rights, options or warrants that by their terms will also be issued to any
Holder upon conversion of a Security into shares of Common Stock without any
action required by the Company or any other Person), the Conversion Rate in
effect at the opening of business on the day following the date fixed for such
determination shall be increased by dividing such Conversion Rate by a fraction
of which the numerator shall be the number of shares of Common Stock outstanding
at the close of business on the date fixed for such determination plus the
number of shares of Common Stock that the aggregate of the offering price of the
total number of shares of Common Stock so offered for subscription or purchase
would purchase at such current market price and the denominator shall be the
number of shares of Common Stock outstanding at the close of business on the
date fixed for such determination plus the number of shares of Common Stock so
offered for subscription or purchase, such increase to become effective
immediately after the opening of business on the day following the date fixed
for such determination. If, after any such date fixed for determination, any
such rights, options or warrants are not in fact issued, or are not exercised
prior to the expiration thereof, the Conversion Rate shall be immediately
readjusted, effective as of the date such rights, options or warrants expire, or
the date the Board of Directors determines not to issue such rights, options or
warrants, to the Conversion Rate that would have been in effect if the
unexercised rights, options or warrants had never been granted or such
determination date had not been fixed, as the case may be. For the purposes of
this paragraph (2), the number of shares of Common Stock at any time outstanding
shall not include shares held in the treasury of the Company but shall include
shares issuable in respect of scrip certificates issued in lieu of fractions of
shares of Common Stock. The Company will not issue any rights, options or
warrants in respect of shares of Common Stock held in the treasury of the
Company.

         (3) In case outstanding shares of Common Stock shall be subdivided into
a greater number of shares of Common Stock, the Conversion Rate in effect at the
opening of business on the day following the day upon which such subdivision
becomes effective shall be proportionately increased, and, conversely, in case
outstanding shares of Common Stock shall be combined into a smaller number of
shares of Common Stock, the Conversion Rate in effect at the opening of business
on the day following the day upon which such subdivision or combination becomes
effective shall be proportionately reduced, such increase or reduction, as the
case may be, to become

                                                                            -81-
<PAGE>
effective immediately after the opening of business on the day following the day
upon which such subdivision or combination becomes effective.

         (4) In case the Company shall, by dividend or otherwise, distribute to
all holders of its Common Stock evidences of its indebtedness, shares of any
class of capital stock or other property (including cash or assets or
securities, but excluding (i) any rights, options or warrants referred to in
paragraph (2) of this Section, (ii) any dividend or distribution paid
exclusively in cash, (iii) any dividend or distribution referred to in paragraph
(1) of this Section, and (iv) any rights issued pursuant to the Rights Plan (as
defined in paragraph (13) of this Section 12.4) except as specified in paragraph
(13) of this Section 12.4, the Conversion Rate shall be adjusted so that the
same shall equal the rate determined by dividing the Conversion Rate in effect
immediately prior to the close of business on the date fixed for the
determination of stockholders entitled to receive such distribution by a
fraction of which the numerator shall be the current market price per share
(determined as provided in paragraph (8) of this Section 12.4) of the Common
Stock on the date fixed for such determination less the then fair market value
(as determined by the Board of directors, whose determination shall be
conclusive and described in a Board Resolution filed with the Trustee) of the
portion of the assets, shares or evidences of indebtedness so distributed
applicable to one share of Common Stock and the denominator shall be such
current market price per share of the Common Stock, such adjustment to become
effective immediately prior to the opening of business on the day following the
date fixed for the determination of stockholders entitled to receive such
distribution. If after any such date fixed for determination, any such
distribution is not in fact made, the Conversion Rate shall be immediately
readjusted, effective as of the date of the Board of Directors determines not to
make such distribution, to the Conversion Rate that would have been in effect if
such determination date had not been fixed.

         (5) In case the Company shall, by dividend or otherwise, distribute to
all holders of its Common Stock, cash (excluding any cash that is distributed as
part of a distribution referred to in paragraph (4) of this Section or cash
distributed upon a merger or consolidation to which Section 12.11 applies) in an
aggregate amount that, combined together with (I) the aggregate amount of any
other all-cash distributions to all holders of its Common Stock made exclusively
in cash within the 365-day period preceding the date of payment of such
distribution and in respect of which no adjustment pursuant to this paragraph
(5) has been made and (II) the aggregate of any cash plus the fair market value
(as determined by the Board of Directors, whose determination shall be
conclusive and described in a Board Resolution) of consideration payable in
respect of any tender offer by the Company or any of its Subsidiaries for all or
any portion of the Common Stock concluded within the 365-day period preceding
the date of payment of such distribution and in respect of which no adjustment
pursuant to paragraph (6) of this Section 12.4 has been made (the "combined cash
and tender amount") exceeds 10% of the product of the current market price per
share (determined as provided in paragraph (8) of this Section 12.4) of the
Common Stock on the date for the determination of holders of shares of Common
Stock entitled to receive such distribution times the number of shares of Common
Stock outstanding on such date (the "aggregate current market price"), then, and
in each such case, immediately after the close of business on such date for
determination, the Conversion Rate shall be adjusted so that the same shall
equal the rate determined by dividing the Conversion Rate in effect immediately
prior to the close of business on the date fixed

                                      -82-
<PAGE>
for determination of the stockholders entitled to receive such distribution by a
fraction (i) the numerator of which shall be equal to the current market price
per share (determined as provided in paragraph (8) of this Section) of the
Common Stock on the date fixed for such determination less an amount equal to
the quotient of (x) the excess of such combined cash and tender amount over 10%
of such aggregate current market price divided by (y) the number of shares of
Common Stock outstanding on such date for determination and (ii) the denominator
of which shall be equal to the current market price per share (determined as
provided in paragraph (8) of this Section 12.4) of the Common Stock on such date
fixed for determination.

         (6) In case a tender offer made by the Company or any Subsidiary for
all or any portion of the Common Stock shall expire and such tender offer (as
amended upon the expiration thereof) shall require the payment to stockholders
(based on the acceptance (up to any maximum specified in the terms of the tender
offer) of Purchased Shares (as defined below)) of an aggregate consideration
having a fair market value (as determined by the Board of Directors, whose
determination shall be conclusive and described in a Board Resolution) that
combined together with (I) the aggregate of the cash plus the fair market value
(as determined by the Board of Directors, whose determination shall be
conclusive and described in a Board Resolution), as of the expiration of such
tender offer, of consideration payable in respect of any other tender offer by
the Company or any Subsidiary for all or any portion of the Common Stock
expiring within the 365-day period preceding the expiration of such tender offer
and in respect of which no adjustment pursuant to this paragraph (6) has been
made and (II) the aggregate amount of any cash distributions to all holders of
the Common Stock within 365-day period preceding the expiration of such tender
offer and in respect of which no adjustment pursuant to paragraph (5) of this
Section has been made (the "combined tender and cash amount") exceeds 10% of the
product of the current market price per share of the Common Stock (determined as
provided in paragraph (8) of this Section 12.4) as of the last time (the
"Expiration Time") tenders could have been made pursuant to such tender offer
(as it may be amended) times the number of shares of Common Stock outstanding
(including any tendered shares) as of the Expiration Time, then, and in each
such case immediately prior to the opening of business on the day after the date
of the Expiration Time, the Conversion Rate shall be adjusted so that the same
shall equal the rate determined by dividing the Conversion Rate immediately
prior to close of business on the date of the Expiration Time by a fraction (i)
the numerator of which shall be equal to (A) the product of (I) the current
market price per share of the Common Stock (determined as provided in paragraph
(8) of this Section 12.4) on the date of the Expiration Time multiplied by (II)
the number of shares of Common Stock outstanding (including any tendered shares)
on the Expiration Time less (B) the combined tender and cash amount, and (ii)
the denominator of which shall be equal to the product of (A) the current market
price per share of the Common Stock (determined as provided in paragraph (8) of
this Section 12.4) as of the Expiration Time multiplied by (B) the number of
shares of Common Stock outstanding (including any tendered shares) as of the
Expiration Time less the number of all shares validly tendered and not withdrawn
as of the Expiration Time (the shares deemed so accepted up to any such maximum,
being referred to as the "Purchased Shares").

         (7) The reclassification of Common Stock into securities other than
Common Stock (other than any reclassification upon a consolidation or merger to
which Section 12.11 applies) shall be deemed to involve (a) a distribution of
such securities other than Common Stock to all holders of

                                      -83-
<PAGE>
Common Stock (and the effective date of such reclassification shall be deemed to
be "the date fixed for the determination of stockholders entitled to receive
such distribution" and "the date fixed for such determination" within the
meaning of paragraph (4) of this Section), and (b) a subdivision or combination,
as the case may be, of the number of shares of Common Stock outstanding
immediately prior to such reclassification into the number of shares of Common
Stock outstanding immediately thereafter (and the effective date of such
reclassification shall be deemed to be "the day upon which such subdivision
becomes effective" or "the day upon which such combination becomes effective",
as the case may be, and "the day upon which such subdivision or combination
becomes effective" within the meaning of paragraph (3) of this Section 12.4).

         (8) For the purpose of any computation under paragraphs (2), (4),
(5) or (6) of this Section 12.4, the current market price per share of Common
Stock on any date shall be calculated by the Company and be the average of the
daily Closing Prices Per Share for the five consecutive Trading Days selected by
the Company commencing not more than 10 Trading Days before, and ending not
later than the earlier of the day in question and the day before the "ex date"
with respect to the issuance or distribution requiring such computation. For
purposes of this paragraph, the term "ex date," when used with respect to any
issuance or distribution, means the first date on which the Common Stock trades
regular way in the applicable securities market or on the applicable securities
exchange without the right to receive such issuance or distribution.

         (9) No adjustment in the Conversion Rate shall be required unless such
adjustment (plus any adjustments not previously made by reason of this paragraph
(9)) would require an increase or decrease of at least one percent in such rate;
provided, however, that any adjustments which by reason of this paragraph (9)
are not required to be made shall be carried forward and taken into account in
any subsequent adjustment. All calculations under this Article shall be made to
the nearest cent or to the nearest one-hundredth of a share, as the case may be.

         (10) The Company may make such increases in the Conversion Rate, for
the remaining term of the Securities or any shorter term, in addition to those
required by paragraphs (1), (2), (3), (4), (5) and (6) of this Section 12.4, as
it considers to be advisable in order to avoid or diminish any income tax to any
holders of shares of Common Stock resulting from any dividend or distribution of
stock or issuance of rights or warrants to purchase or subscribe for stock or
from any event treated as such for income tax purposes. The Company shall have
the power to resolve any ambiguity or correct any error in this paragraph (10)
and its actions in so doing shall, absent manifest error, be final and
conclusive.

         (11) Notwithstanding the foregoing provisions of this Section, no
adjustment of the Conversion Rate shall be required to be made (a) upon the
issuance of shares of Common Stock pursuant to any present or future plan for
the reinvestment of dividends or (b) because of a tender or exchange offer of
the character described in Rule 13e-4(h)(5) under the Exchange Act or any
successor rule thereto.

         (12) To the extent permitted by applicable law, the Company from time
to time may increase the Conversion Rate by any amount for any period of time if
the period is at least twenty (20) days, the increase is irrevocable during such
period, and the Board of Directors shall have made

                                                                            -84-
<PAGE>
a determination that such increase would be in the best interests of the
Company, which determination shall be conclusive; provided, however, that no
such increase shall be taken into account for purposes of determining whether
the Closing Price Per Share of the Common Stock equals or exceeds 105% of the
Conversion Price in connection with an event which would otherwise be a Change
in Control pursuant to Section 14.3. Whenever the Conversion Rate is increased
pursuant to the preceding sentence, the Company shall give notice of the
increase to the Holders in the manner provided in Section 1.6 at least fifteen
(15) days prior to the date the increased Conversion Rate takes effect, and such
notice shall state the increased Conversion Rate and the period during which it
will be in effect.

         (13) Pursuant to rights issued under any rights Plan of the Company's
(the "Rights Plan"), to the extent the Rights Plan is still in effect, upon
conversion of any Security by the holder thereof, such holders will receive, in
addition to the Common Stock issuable upon such conversion, the rights described
in the Rights Plan, whether or not the rights have separated from the underlying
Common Stock at the time of conversion, unless the distribution of such rights
would cause certain tax implications as specified in the Rights Plan, in which
case the holder shall not receive such rights upon conversion, and in lieu
thereof, the Conversion Rate will be adjusted effective immediately prior to
conversion pursuant paragraph (4) of this Section 12.4, as though such rights
had been distributed to holders of Common Stock on the day immediately preceding
the conversion date.

SECTION 12.5      Notice of Adjustments of Conversion Rate.

         Whenever the Conversion Rate is adjusted as herein provided:

         (1) the Company shall compute the adjusted Conversion Rate in
accordance with Section 12.4 and shall prepare a certificate signed by the Chief
Financial Officer of the Company setting forth the adjusted Conversion Rate and
showing in reasonable detail the facts upon which such adjustment is based, and
such certificate shall promptly be filed with the Trustee and with each
Conversion Agent; and

         (2) upon each such adjustment, a notice stating that the Conversion
Rate has been adjusted and setting forth the adjusted Conversion Rate shall be
required, and as soon as practicable after it is required, such notice shall be
provided by the Company to all Holders in accordance with Section 1.6.

         Neither the Trustee nor any Conversion Agent shall be under any duty or
responsibility with respect to any such certificate or the information and
calculations contained therein, except to exhibit the same to any Holder of
Securities desiring inspection thereof at its office during normal business
hours, and shall not be deemed to have knowledge of any adjustment in the
Conversion Rate unless and until a Responsible Officer of the Trustee shall have
received such a certificate. Until a Responsible Officer of the Trustee receives
such a certificate, the Trustee and each Conversion Agent may assume without
inquiry that the last Conversion Rate of which the Trustee has knowledge of
remains in effect.

                                                                            -85-

SECTION 12.6      Notice of Certain Corporate Action.

         In case:

         (1) the Company shall declare a dividend (or any other distribution) on
its Common Stock payable (i) otherwise than exclusively in cash or (ii)
exclusively in cash in an amount that would require any adjustment pursuant to
Section 12.4; or

         (2) the Company shall authorize the granting to all or substantially
all of the holders of its Common Stock of rights, options or warrants to
subscribe for or purchase any shares of capital stock of any class or of any
other rights; or

         (3) of any reclassification of the Common Stock, or of any
consolidation, merger or share exchange to which the Company is a party and for
which approval of any stockholders of the Company is required, or of the
conveyance, sale, transfer or lease of all or substantially all of the assets of
the Company; or

         (4) of the voluntary or involuntary dissolution, liquidation or winding
up of the Company;

then the Company shall cause to be filed at each office or agency maintained for
the purpose of conversion of Securities pursuant to Section 10.2, and shall
cause to be provided to all Holders in accordance with Section 1.6, at least 20
days (or 10 days in any case specified in clause (1) or (2) above) prior to the
applicable record or effective date hereinafter specified, a notice stating (x)
the date on which a record is to be taken for the purpose of such dividend,
distribution, rights, options or warrants, or, if a record is not to be taken,
the date as of which the holders of Common Stock of record to be entitled to
such dividend, distribution, rights, options or warrants are to be determined or
(y) the date on which such reclassification, consolidation, merger, conveyance,
transfer, sale, lease, dissolution, liquidation or winding up is expected to
become effective, and the date as of which it is expected that holders of Common
Stock of record shall be entitled to exchange their shares of Common Stock for
securities, cash or other property deliverable upon such reclassification,
consolidation, merger, conveyance, transfer, sale, lease, dissolution,
liquidation or winding up. Neither the failure to give such notice or the notice
referred to in the following paragraph nor any defect therein shall affect the
legality or validity of the proceedings described in clauses (1) through (4) of
this Section 12.6. If at the time the Trustee shall not be the conversion agent,
a copy of such notice shall also forthwith be filed by the Company with the
Trustee.

         The Company shall cause to be filed at the Corporate Trust Office and
each office or agency maintained for the purpose of conversion of Securities
pursuant to Section 10.2, and shall cause to be provided to all Holders in
accordance with Section 1.6, notice of any tender offer by the Company or any
Subsidiary for all or any portion of the Common Stock at or about the time that
such notice of tender offer is provided to the public generally.

                                                                            -86-

SECTION 12.7 Company to Reserve Common Stock.

         The Company shall at all times reserve and keep available, free from
preemptive rights, out of its authorized but unissued Common Stock, for the
purpose of effecting the conversion of Securities, the full number of shares of
Common Stock then issuable upon the conversion of all Outstanding Securities.

SECTION 12.8 Taxes on Conversions.

         Except as provided in the next sentence, the Company will pay any and
all taxes and duties that may be payable in respect of the issue or delivery of
shares of Common Stock on conversion of Securities pursuant hereto. The Company
shall not, however, be required to pay any tax or duty that may be payable in
respect of (i) income of the Holder, or (ii) any transfer involved in the issue
and delivery of shares of Common Stock in a name other than that of the Holder
of the Security or Securities to be converted, and no such issue or delivery
shall be made unless and until the Person requesting such issue has paid to the
Company the amount of any such tax or duty, or has established to the
satisfaction of the Company that such tax or duty has been paid.

SECTION 12.9 Covenant as to Common Stock.

         The Company agrees that all shares of Common Stock that may be
delivered upon conversion of Securities, upon such delivery, will have been duly
authorized and validly issued and will be fully paid and nonassessable and,
except as provided in Section 12.8, the Company will pay all taxes, liens and
charges with respect to the issue thereof.

SECTION 12.10     Cancellation of Converted Securities.

         All Securities delivered for conversion shall be delivered to the
Trustee or its agent to be canceled by or at the direction of the Trustee, which
shall dispose of the same as provided in Section 3.9.

SECTION 12.11 Provision in Case of Reclassification, Consolidation, Merger or
              Sale of Assets.

         In case of (i) any reclassification or change of the outstanding shares
of Common Stock (other than a change in par value, or from par value to no par
value, or from no par value to par value, or as a result of a subdivision or
combination), (ii) any consolidation or merger of the Company with or into any
other Person, any merger of another Person with or into the Company (other than
a merger that does not result in any reclassification, conversion, exchange or
cancellation of outstanding shares of Common Stock of the Company) or (iii) any
conveyance, sale, transfer or lease of all or substantially all of the assets of
the Company (other than a sale of all or substantially all of the assets of the
Company that does not result in any reclassification, conversion, exchange or
cancellation of outstanding shares of Common Stock of the Company), the Person
formed by such consolidation or resulting from such merger or which acquires
such assets, as the case may be, shall execute and deliver to the Trustee a
supplemental indenture providing that the Holder of each

                                                                            -87-
<PAGE>
Security then Outstanding shall have the right thereafter, during the period
such Security shall be convertible as specified in Section 12.1, to convert such
Security only into the kind and amount of securities, cash and other property
receivable upon such consolidation, merger, conveyance, sale, transfer or lease
by a holder of the number of shares of Common Stock of the Company into which
such Security might have been converted immediately prior to such consolidation,
merger, conveyance, sale, transfer or lease, assuming such holder of Common
Stock of the Company (i) is not (A) a Person with which the Company consolidated
or merged with or into or which merged into or with the Company or to which such
conveyance, sale, transfer or lease was made, as the case may be (a "Constituent
Person"), or (B) an Affiliate of a Constituent Person and (ii) failed to
exercise his rights of election, if any, as to the kind or amount of securities,
cash and other property receivable upon such consolidation, merger, conveyance,
sale, transfer or lease (provided that if the kind or amount of securities, cash
and other property receivable upon such consolidation, merger, conveyance, sale,
transfer, or lease is not the same for each share of Common Stock of the Company
held immediately prior to such consolidation, merger, conveyance, sale, transfer
or lease by others than a Constituent Person or an Affiliate thereof and in
respect of which such rights of election shall not have been exercised
("Non-electing Share"), then for the purpose of this Section 12.11 the kind and
amount of securities, cash and other property receivable upon such
consolidation, merger, conveyance, sale, transfer or lease by the holders of
each Non-electing Share shall be deemed to be the kind and amount so receivable
per share by a plurality of the Non-electing Shares). Such supplemental
indenture shall provide for adjustments that, for events subsequent to the
effective date of such supplemental indenture, shall be as nearly equivalent as
may be practicable to the adjustments provided for in this Article. The above
provisions of this Section 12.11 shall similarly apply to successive
consolidations, mergers, conveyances, sales, transfers or leases. Notice of the
execution of such a supplemental indenture shall be given by the Company to the
Holder of each Security as provided in Section 1.6 promptly upon such execution.

         Neither the Trustee nor any Conversion Agent shall be under any
responsibility to determine the correctness of any provisions contained in any
such supplemental indenture relating either to the kind or amount of shares of
stock or other securities or property or cash receivable by Holders of
Securities upon the conversion of their Securities after any such consolidation,
merger, conveyance, transfer, sale or lease or to any such adjustment, but may
accept as conclusive evidence of the correctness of any such provisions, and
shall be protected in relying upon, an Opinion of Counsel with respect thereto,
which the Company shall cause to be furnished to the Trustee upon request.

SECTION 12.12 Rights Issued in Respect of Common Stock.

         Rights or warrants distributed by the Company to all holders of Common
Stock entitling the holders thereof to subscribe for or purchase shares of the
Company's capital stock (either initially or under certain circumstances), which
rights or warrants, until the occurrence of a specified event or events
("Trigger Event"):

            (i) are deemed to be transferred with such shares of Common Stock,

            (ii) are not exercisable, and

                                                                            -88-
<PAGE>
            (iii) are also issued in respect of future issuances of Common Stock

shall not be deemed distributed for purposes of Section 12.4(2) until the
occurrence of the earliest Trigger Event. In addition, in the event of any
distribution of rights or warrants, or any Trigger Event with respect thereto,
that shall have resulted in an adjustment to the Conversion Rate under Section
12.4(2), (1) in the case of any such rights or warrants that shall all have been
redeemed or repurchased without exercise by any holders thereof, the Conversion
Rate shall be readjusted upon such final redemption or repurchase to give effect
to such distribution or Trigger Event, as the case may be, as though it were a
cash distribution, equal to the per share redemption or repurchase price
received by a holder of Common Stock with respect to such rights or warrants
(assuming such holder had retained such rights or warrants), made to all holders
of Common Stock as of the date of such redemption or repurchase, and (2) in the
case of any such rights or warrants all of which shall have expired without
exercise by any holder thereof, the Conversion Price shall be readjusted as if
such issuance had not occurred.

SECTION 12.13 Responsibility of Trustee for Conversion Provisions.

         The Trustee, subject to the provisions of Section 6.1, and any
Conversion Agent shall not at any time be under any duty or responsibility to
any Holder of Securities to determine whether any facts exist which may require
any adjustment of the Conversion Rate, or with respect to the nature or extent
of any such adjustment when made, or with respect to the method employed, herein
or in any supplemental indenture provided to be employed, in making the same, or
whether a supplemental indenture need be entered into. Neither the Trustee,
subject to the provisions of Section 6.1, nor any Conversion Agent shall be
accountable with respect to the validity or value (or the kind or amount) of any
Common Stock, or of any other securities or property or cash, which may at any
time be issued or delivered upon the conversion of any Security; and it or they
do not make any representation with respect thereto. Neither the Trustee,
subject to the provisions of Section 6.1, nor any Conversion Agent shall be
responsible for any failure of the Company to make or calculate any cash payment
or to issue, transfer or deliver any shares of Common Stock or share
certificates or other securities or property or cash upon the surrender of any
Security for the purpose of conversion; and the Trustee, subject to the
provisions of Section 6.1, and any Conversion Agent shall not be responsible for
any failure of the Company to comply with any of the covenants of the Company
contained in this Article.

                                  ARTICLE XIII
                           SUBORDINATION OF SECURITIES

SECTION 13.1 Securities Subordinate to Senior Debt.

         The Company covenants and agrees, and each Holder of a Security, by its
acceptance thereof, likewise covenants and agrees, that, to the extent and in
the manner hereinafter set forth in this Article (subject to the provisions of
Article IV), the indebtedness represented by the Securities and the payment of
the principal of, or premium, if any, or interest (including Liquidated Damages,
if any) on, each and all of the Securities (including, but not limited to, the
Redemption Price with respect to the Securities to be called for redemption in
accordance with Article XI or the Repurchase

                                                                            -89-
<PAGE>
Price with respect to Securities submitted for repurchase in accordance with
Article XIV), are hereby expressly made subordinate and subject in right of
payment to the prior payment in full of all Senior Debt.

SECTION 13.2 No Payment in Certain Circumstances, Payment over of Proceeds upon
             Dissolution, Etc.

         No payment shall be made with respect to the principal of, or premium,
if any, or interest (including Liquidated Damages, if any) on the Securities
(including, but not limited to, the Redemption Price with respect to the
Securities to be called for redemption in accordance with Article XI or the
Repurchase Price with respect to Securities submitted for repurchase in
accordance with Article XIV), except payments and distributions made by the
Trustee as permitted by Section 13.9, if:

            (i) a default in the payment of principal, premium, if any, or
interest (including a default under any repurchase or redemption obligation) or
other amounts with respect to any Designated Senior Debt occurs and is
continuing (or, in the case of Designated Senior Debt for which there is a
period of grace, in the event of such a default that continues beyond the period
of grace, if any, specified in the instrument or lease evidencing such
Designated Senior Debt) unless and until such default shall have been cured or
waived or shall have ceased to exist; or

            (ii) any other event of default occurs and is continuing with
respect to Designated Senior Debt that then permits holders of such Designated
Senior Debt to accelerate its maturity and the Trustee has received a notice of
the default (a "Payment Blockage Notice") from a Representative or holder of
Designated Senior Debt or the Company.

         If the Trustee receives any Payment Blockage Notice pursuant to clause
(ii) above, no subsequent Payment Blockage Notice shall be effective for
purposes of this Section unless and until (A) at least 365 days shall have
elapsed since the initial effectiveness of the immediately prior Payment
Blockage Notice, and (B) all scheduled payments of principal, premium, if any,
and interest on the Securities that have come due have been paid in full in
cash. No nonpayment default that existed or was continuing on the date of
delivery of any Payment Blockage Notice to the Trustee shall be, or be made, the
basis for a subsequent Payment Blockage Notice.

         The Company may and shall resume payments on and distributions in
respect of the Securities upon the earlier of:

         (1) in the case of a default referred to in clause (i) above, the date
upon which the default is cured or waived or ceases to exist, or

         (2) in the case of a default referred to in clause (ii) above, the date
upon which the default is cured or waived or ceases to exist or 179 days pass
after notice is received if the maturity of such Designated Senior Debt has not
been accelerated, unless this Article XIII otherwise prohibits the payment or
distribution at the time of such payment or distribution.

                                                                            -90-
<PAGE>
         In the event of (a) any insolvency or bankruptcy case or proceeding, or
any receivership, liquidation, reorganization or other similar case or
proceeding in connection therewith, relative to the Company or to its creditors,
as such, or to its assets, or (b) any liquidation, dissolution or other winding
up of the Company, whether voluntary or involuntary and whether or not involving
insolvency or bankruptcy, or (c) any assignment for the benefit of creditors or
any other marshaling of assets and liabilities of the Company, then and in any
such event the holders of Senior Debt shall be entitled to receive payment in
full of all amounts due or to become due on or in respect of all Senior Debt in
cash before the Holders of the Securities are entitled to receive any payment on
account of principal of (or premium, if any) or interest (including any
Liquidated Damages) on the Securities or on account of the purchase, redemption
or other acquisition of Securities, and to that end the holders of Senior Debt
shall be entitled to receive, for application to the payment thereof, any
payment or distribution of any kind or character, whether in cash, property or
securities, which may be payable or deliverable in respect of the Securities in
any such case, proceeding, dissolution, liquidation or other winding up or
event.

         In the event that, notwithstanding the foregoing provisions of this
Section, the Trustee or the Holder of any Security shall have received any
payment or distribution of assets of the Company of any kind or character,
whether in cash, securities or other property, before all Senior Debt is paid in
full, and if such fact shall, at or prior to the time of such payment or
distribution, have been made known to the Trustee or, as the case may be, such
Holder, then and in such event such payment or distribution shall be paid over
or delivered forthwith to the trustee in bankruptcy, receiver, liquidating
trustee, custodian, assignee, agent or other Person making payment or
distribution of assets of the Company for application to the payment of all
Senior Debt remaining unpaid, to the extent necessary to pay all Senior Debt in
full, after giving effect to any concurrent payment or distribution to or for
the holders of Senior Debt.

         For purposes of this Article only, the words "cash, securities or other
property" shall not be deemed to include shares of capital stock of the Company
as reorganized or readjusted, or securities of the Company or any other
corporation provided for by a plan of reorganization or readjustment, which
shares of capital stock or securities are subordinated in right of payment to
all then outstanding Senior Debt to substantially the same extent as, or to a
greater extent than, the Securities are so subordinated as provided in this
Article. The consolidation of the Company with, or the merger of the Company
into, another Person or the liquidation or dissolution of the Company following
the conveyance or transfer of its properties and assets substantially as an
entirety to another Person upon the terms and conditions set forth in Article
VII shall not be deemed a dissolution, winding up, liquidation, reorganization,
assignment for the benefit of creditors or marshaling of assets and liabilities
of the Company for the purposes of this Section if the Person formed by such
consolidation or into which the Company is merged or which acquires by
conveyance or transfer such properties and assets substantially as an entirety,
as the case may be, shall, as a part of such consolidation, merger, conveyance
or transfer, comply with the conditions set forth in Article VII.

         In the event that, notwithstanding the foregoing, the Company shall
make any payment to the Trustee or the Holder of any Security prohibited by the
foregoing provisions of this Section, and if

                                                                            -91-
<PAGE>
such fact shall, at or prior to the time of such payment, have been made known
to the Trustee or, as the case may be, such Holder, then and in such event such
payment shall be paid over and delivered forthwith to the Company, in the case
of the Trustee, or the Trustee, in the case of such Holder.

SECTION 13.3 Prior Payment to Senior Debt upon Acceleration of Securities.

         In the event of the acceleration of the Securities because of an Event
of Default, no payment or distribution shall be made to the Trustee or any
holder of Securities in respect of the principal of, premium, if any, or
interest (including Liquidated Damages, if any) on the Securities (including,
but not limited to, the Redemption Price with respect to the Securities called
for redemption in accordance with Article XI or the Repurchase Price with
respect to the Securities submitted for repurchase in accordance with Article
XIV), except payments and distributions made by the Trustee as permitted by
Section 13.9, until all Senior Debt has been paid in full in cash or other
payment satisfactory to the holders of Senior Debt or such acceleration is
rescinded in accordance with the terms of this Indenture. If payment of the
Securities is accelerated because of an Event of Default, the Company shall
promptly notify holders of Senior Debt of the acceleration.

SECTION 13.4 Payment Permitted If No Default.

         Nothing contained in this Article or elsewhere in this Indenture or in
any of the Securities shall prevent (a) the Company, at any time except during
the pendency of any case, proceeding, dissolution, liquidation or other winding
up, assignment for the benefit of creditors or other marshaling of assets and
liabilities of the Company referred to in Section 13.2, or during the
circumstances referred to in the first paragraph of Section 13.2, or under the
conditions described in Section 13.3, from making payments at any time of
principal of (and premium, if any) or interest on the Securities, or (b) the
application by the Trustee of any money deposited with it hereunder to the
payment of or on account of the principal of (and premium, if any) or interest
on the Securities or the retention of such payment by the Holders, if, at the
time of such application by the Trustee, it did not have knowledge that such
payment would have been prohibited by the provisions of this Article.

SECTION 13.5 Subrogation to Rights of Holders of Senior Debt.

         Subject to the payment in full of all Senior Debt, the Holders of the
Securities shall be subrogated to the extent of the payments or distributions
made to the holders of such Senior Debt pursuant to the provisions of this
Article to the rights of the holders of such Senior Debt to receive payments and
distributions of cash, property and securities applicable to the Senior Debt
until the principal of (and premium, if any) and interest on the Securities
shall be paid in full. For purposes of such subrogation, no payments or
distributions to the holders of the Senior Debt of any cash, property or
securities to which the Holders of the Securities or the Trustee would be
entitled except for the provisions of this Article, and no payments over
pursuant to the provisions of this Article to the holders of Senior Debt by
Holders of the Securities or the Trustee, shall, as among the Company, its
creditors other than holders of Senior Debt and the Holders of the Securities,
be deemed to be a payment or distribution by the Company to or on account of the
Senior Debt.

                                                                            -92-

SECTION 13.6 Provisions Solely to Define Relative Rights.

         The provisions of this Article are and are intended solely for the
purpose of defining the relative rights of the Holders of the Securities on the
one hand and the holders of Senior Debt on the other hand. Nothing contained in
this Article or elsewhere in this Indenture or in the Securities is intended to
or shall (i) impair, as among the Company, its creditors other than holders of
Senior Debt and the Holders of the Securities, the obligation of the Company,
which is absolute and unconditional, to pay to the Holders of the Securities the
principal of (and premium, if any) and interest (including Liquidated Damages,
if any) on the Securities as and when the same shall become due and payable in
accordance with their terms; or (ii) affect the relative rights against the
Company of the Holders of the Securities and creditors of the Company other than
the holders of Senior Debt; or (iii) prevent the Trustee or the Holder of any
Security from exercising all remedies otherwise permitted by applicable law upon
default under this Indenture, subject to the rights, if any, under this Article
of the holders of Senior Debt to receive cash, property and securities otherwise
payable or deliverable to the Trustee or such Holder.

SECTION 13.7 Trustee to Effectuate Subordination.

         Each Holder of a Security by its acceptance thereof authorizes and
directs the Trustee on its behalf to take such action as may be necessary or
appropriate to effectuate the subordination provided in this Article and
appoints the Trustee its attorney-in-fact for any and all such purposes.

SECTION 13.8 No Waiver of Subordination Provisions.

         No right of any present or future holder of any Senior Debt to enforce
subordination as herein provided shall at any time in any way be prejudiced or
impaired by any act or failure to act on the part of the Company, or by any
non-compliance by the Company with the terms, provisions and covenants of this
Indenture, regardless of any knowledge thereof any such holder may have or be
otherwise charged with.

         Without in any way limiting the generality of the foregoing paragraph,
the holders of Senior Debt may, at any time and from time to time, without the
consent of or notice to the Trustee or the Holders of the Securities, without
incurring responsibility to the Holders of the Securities and without impairing
or releasing the subordination provided in this Article or the obligations
hereunder of the Holders of the Securities to the holders of Senior Debt, do any
one or more of the following: (i) change the manner, place or terms of payment
or extend the time of payment of, or renew or alter, Senior Debt, or otherwise
amend or supplement in any manner Senior Debt or any instrument evidencing the
same or any agreement under which Senior Debt is outstanding; (ii) sell,
exchange, release or otherwise deal with any property pledged, mortgaged or
otherwise securing Senior Debt; (iii) release any Person liable in any manner
for the collection of Senior Debt; and (iv) exercise or refrain from exercising
any rights against the Company and any other Person.

                                                                            -93-

SECTION 13.9 Notice to Trustee.

         The Company shall give prompt written notice to the Trustee of any fact
known to the Company that would prohibit the making of any payment to or by the
Trustee in respect of the Securities. Notwithstanding the provisions of this
Article or any other provision of this Indenture, the Trustee shall not be
charged with knowledge of the existence of any facts which would prohibit the
making of any payment to or by the Trustee in respect of the Securities, unless
and until a Responsible Officer of the Trustee shall have received written
notice thereof from the Company or a Representative or a holder of Senior Debt
(including, without limitation, a holder of Designated Senior Debt) and, prior
to the receipt of any such written notice, the Trustee, subject to the
provisions of Section 6.1, shall be entitled in all respects to assume that no
such facts exist; provided, however, that if the Trustee shall not have received
the notice provided for in this Section 13.9 at least two Business Days prior to
the date upon which by the terms hereof any money may become payable for any
purpose (including, without limitation, the payment of the principal of (and
premium, if any) or interest (including Liquidated Damages, if any) on any
Security), then, anything herein contained to the contrary notwithstanding, the
Trustee shall have full power and authority to receive such money and to apply
the same to the purpose for which such money was received and shall not be
affected by any notice to the contrary which may be received by it within one
Business Day prior to such date.

         Notwithstanding anything in this Article XIII to the contrary, nothing
shall prevent any payment by the Trustee to the Holders of monies deposited with
it pursuant to Section 4.1, and any such payment shall not be subject to the
provisions of Section 13.2 or 13.3.

         Subject to the provisions of Section 6.1, the Trustee shall be entitled
to rely on the delivery to it of a written notice by a Person representing
himself to be a Representative or a holder of Senior Debt (including, without
limitation, a holder of Designated Senior Debt) to establish that such notice
has been given by a Representative or a holder of Senior Debt (including,
without limitation, a holder of Designated Senior Debt). In the event that the
Trustee determines in good faith that further evidence is required with respect
to the right of any Person as a holder of Senior Debt to participate in any
payment or distribution pursuant to this Article, the Trustee may request such
Person to furnish evidence to the reasonable satisfaction of the Trustee as to
the amount of Senior Debt held by such Person, the extent to which such Person
is entitled to participate in such payment or distribution and any other facts
pertinent to the rights of such Person under this Article, and if such evidence
is not furnished, the Trustee may defer any payment to such Person pending
judicial determination as to the right of such Person to receive such payment.

SECTION 13.10 Reliance on Judicial Order or Certificate of Liquidating Agent.

         Upon any payment or distribution of assets of the Company referred to
in this Article, the Trustee, subject to the provisions of Section 6.1, and the
Holders of the Securities shall be entitled to rely upon any order or decree
entered by any court of competent jurisdiction in which such insolvency,
bankruptcy, receivership, liquidation, reorganization, dissolution, winding up
or similar case or proceeding is pending, or a certificate of the trustee in
bankruptcy, receiver, liquidating trustee, custodian, assignee for the benefit
of creditors, agent or other Person making such payment

                                                                            -94-
<PAGE>
or distribution, delivered to the Trustee or to the Holders of Securities, for
the purpose of ascertaining the Persons entitled to participate in such payment
or distribution, the holders of the Senior Debt and other indebtedness of the
Company, the amount thereof or payable thereon, the amount or amounts paid or
distributed thereon and all other facts pertinent thereto or to this Article.

SECTION 13.11 Trustee Not Fiduciary for Holders of Senior Debt.

         The Trustee shall not be deemed to owe any fiduciary duty to the
holders of Senior Debt and shall not be liable to any such holders if it shall
in good faith mistakenly pay over or distribute to Holders of Securities or to
the Company or to any other Person cash, property or securities to which any
holders of Senior Debt shall be entitled by virtue of this Article or otherwise.

SECTION 13.12 Reliance by Holders of Senior Debt on Subordination Provisions.

         Each Holder by accepting a Security acknowledges and agrees that the
foregoing subordination provisions are, and are intended to be, an inducement
and a consideration to each holder of any Senior Debt, whether such Senior Debt
was created or acquired before or after the issuance of the Securities, to
acquire and continue to hold, or to continue to hold, such Senior Debt and such
holder of Senior Debt shall be deemed conclusively to have relied on such
subordination provisions in acquiring and continuing to hold, or in continuing
to hold, such Senior Debt, and no amendment or modification of the provisions
contained herein shall diminish the rights of such holders of Senior Debt unless
such holders shall have agreed in writing thereto.

SECTION 13.13 Rights of Trustee as Holder of Senior Debt; Preservation of
              Trustee's Rights.

         The Trustee in its individual capacity shall be entitled to all the
rights set forth in this Article with respect to any Senior Debt which may at
any time be held by it, to the same extent as any other holder of Senior Debt,
and nothing in this Indenture shall deprive the Trustee of any of its rights as
such holder.

         Nothing in this Article shall apply to claims of, or payments to, the
Trustee under or pursuant to Section 6.7.

SECTION 13.14 Article Applicable to Paying Agents.

         In case at any time any Paying Agent other than the Trustee shall have
been appointed by the Company and be then acting hereunder, the term "Trustee"
as used in this Article shall in such case (unless the context otherwise
requires) be construed as extending to and including such Paying Agent within
its meaning as fully for all intents and purposes as if such Paying Agent were
named in this Article in addition to or in place of the Trustee; provided,
however, that Section 13.13 shall not apply to the Company or any Affiliate of
the Company if it or such Affiliate acts as Paying Agent.

                                                                            -95-

SECTION 13.15 Certain Conversions and Repurchases Deemed Payment.

         For the purposes of this Article only, (i) the issuance and delivery of
junior securities upon conversion of Securities in accordance with Article XII
or upon the repurchase of Securities in accordance with Article XIV shall not be
deemed to constitute a payment or distribution on account of the principal of or
premium or interest (including Liquidated Damages, if any) on Securities or on
account of the purchase or other acquisition of Securities, and (ii) the
payment, issuance or delivery of cash (except in satisfaction of fractional
shares pursuant to Section 12.3), property or securities (other than junior
securities) upon conversion of a Security shall be deemed to constitute payment
on account of the principal of such Security. For the purposes of this Section,
the term "junior securities" means (a) shares of any stock of any class of the
Company and securities into which the Securities are convertible pursuant to
Article XII and (b) securities of the Company which are subordinated in right of
payment to all Senior Debt that may be outstanding at the time of issuance or
delivery of such securities to substantially the same extent as, or to a greater
extent than, the Securities are so subordinated as provided in this Article.
Nothing contained in this Article or elsewhere in this Indenture or in the
Securities is intended to or shall impair, as among the Company, its creditors
other than holders of Senior Debt and the Holders of the Securities, the right,
which is absolute and unconditional, of the Holder of any Security to convert
such Security in accordance with Article XII or to exchange such Security for
Common Stock in accordance with Article XIV if the Company elects to satisfy the
obligations under Article XIV by the delivery of Common Stock.

                                  ARTICLE XIV
                  REPURCHASE OF SECURITIES AT THE OPTION OF THE
                         HOLDER UPON A CHANGE IN CONTROL

SECTION 14.1 Right to Require Repurchase.

         In the event that a Change in Control (as hereinafter defined) shall
occur, then each Holder shall have the right, at the Holder's option, to require
the Company to repurchase, and upon the exercise of such right the Company shall
repurchase, all of such Holder's Securities not theretofore called for
redemption, or any portion of the principal amount thereof that is equal to
U.S.$1,000 or any integral multiple of U.S.$1,000 in excess thereof (provided
that no single Security may be repurchased in part unless the portion of the
principal amount of such Security to be Outstanding after such repurchase is
equal to U.S.$1,000 or integral multiples of U.S.$1,000 in excess thereof), on
the date (the "Repurchase Date") that is 30 Business Days after the date of the
Company Notice (as defined in Section 14.2) at a purchase price equal to 100% of
the principal amount of the Securities to be repurchased plus interest accrued
but unpaid to, but excluding, the Repurchase Date (the "Repurchase Price");
provided, however, that installments of interest on Securities whose Stated
Maturity is on or prior to the Repurchase Date shall be payable to the Holders
of such Securities, or one or more Predecessor Securities, registered as such on
the relevant Record Date according to their terms and the provisions of Section
3.7. Such right to require the repurchase of the Securities shall not continue
after a discharge of the Company from its obligations with respect to the
Securities in accordance with Article IV, unless a Change in Control shall have
occurred prior to such discharge. Whenever in this Indenture (including Sections
2.2, 3.1, 5.1(1) and 5.8) there is a reference, in any

                                                                            -96-
<PAGE>
context, to the principal of any Security as of any time, such reference shall
be deemed to include reference to the Repurchase Price payable in respect of
such Security to the extent that such Repurchase Price is, was or would be so
payable at such time, and express mention of the Repurchase Price in any
provision of this Indenture shall not be construed as excluding the Repurchase
Price in those provisions of this Indenture when such express mention is not
made; provided, however, that for the purposes of Article XIII such reference
shall be deemed to include reference to the Repurchase Price only to the extent
the Repurchase Price is payable in cash.

SECTION 14.2 Notices; Method of Exercising Repurchase Right, Etc.

         (1) Unless the Company shall have theretofore called for redemption all
of the Outstanding Securities, on or before the 30th day after the occurrence of
a Change in Control, the Company or, at the request and expense of the Company
on or before the 15th day after such occurrence, the Trustee, shall give to all
Holders of Securities, in the manner provided in Section 1.6, notice (the
"Company Notice") of the occurrence of the Change in Control and of the
repurchase right set forth herein arising as a result thereof and the Company
shall issue a Press Release including the information required to be included in
such Company Notice hereunder. The Company shall also deliver a copy of such
Company Notice to the Trustee.

         Each Company Notice shall state:

            (i) the Repurchase Date,

            (ii) the date by which the repurchase right must be exercised,

            (iii) the Repurchase Price,

            (iv) a description of the procedure that a Holder must follow to
exercise a repurchase right, and the place or places where such Securities are
to be surrendered for payment of the Repurchase Price and accrued interest
(including Liquidated Damages, if any), if any to the Repurchase Date,

            (v) that on the Repurchase Date the Repurchase Price, and accrued
interest (including Liquidated Damages, if any), if any to the Repurchase Date,
will become due and payable upon each such Security designated by the Holder to
be repurchased, and that interest thereon shall cease to accrue on and after
said date,

            (vi) the Conversion Rate then in effect, the date on which the right
to convert the principal amount of the Securities to be repurchased will
terminate and the place or places where such Securities may be surrendered for
conversion, and

            (vii) the place or places that the Security certificate with the
Election of Holder to Require Repurchase as specified in Section 2.2 shall be
delivered.

                                                                            -97-
<PAGE>
         No failure of the Company to give the foregoing notices or defect
therein shall limit any Holder' s right to exercise a repurchase right or affect
the validity of the proceedings for the repurchase of Securities.

         If any of the foregoing provisions or other provisions of this Article
XIV are inconsistent with applicable law, such law shall govern.

         (2) To exercise a repurchase right, a Holder shall deliver to the
Trustee on or before the close of business on the Business Day prior to the
Repurchase Date (i) irrevocable written notice of the Holder's exercise of such
right, which notice shall set forth the name of the Holder, the principal amount
of the Securities to be repurchased (and, if any Security is to repurchased in
part, the serial number thereof, the portion of the principal amount thereof to
be repurchased and the name of the Person in which the portion thereof to remain
Outstanding after such repurchase is to be registered) and a statement that an
election to exercise the repurchase right is being made thereby, and, in the
event that the Repurchase Price shall be paid in shares of Common Stock, the
name or names (with addresses) in which the certificate or certificates for
shares of Common Stock shall be issued, and (ii) the Securities with respect to
which the repurchase right is being exercised. Such written notice shall be
irrevocable, except that the right of the Holder to convert the Securities with
respect to which the repurchase right is being exercised shall continue until
the close of business on the Business Day immediately preceding the Repurchase
Date.

         (3) In the event a repurchase right shall be exercised in accordance
with the terms hereof, the Company shall pay or cause to be paid to the Trustee
the Repurchase Price in cash, as provided above, for payment to the Holder on
the Repurchase Date, together with accrued and unpaid interest to the Repurchase
Date payable with respect to the Securities as to which the repurchase right has
been exercised; provided, however, that installments of interest that mature on
or prior to the Repurchase Date shall be payable in cash to the Holders of such
Securities, or one or more Predecessor Securities, registered as such at the
close of business on the relevant Regular Record Date.

         (4) If any Security (or portion thereof) surrendered for repurchase
shall not be so paid on the Repurchase Date, the principal amount of such
Security (or portion thereof, as the case may be) shall, until paid, bear
interest to the extent permitted by applicable law from the Repurchase Date at
the rate of 4.5% per annum, and each Security shall remain convertible into
Common Stock until the principal of such Security (or portion thereof, as the
case may be) shall have been paid or duly provided for.

         (5) Any Security that is to be repurchased only in part shall be
surrendered to the Trustee (with, if the Company or the Trustee so requires, due
endorsement by, or a written instrument of transfer in form satisfactory to the
Company and the Trustee duly executed by, the Holder thereof or his attorney
duly authorized in writing), and the Company shall execute, and the Trustee
shall authenticate and make available for delivery to the Holder of such
Security without service charge, a new Security or Securities, containing
identical terms and conditions, each in an authorized denomination in aggregate
principal amount equal to and in exchange for the unrepurchased portion of the
principal of the Security so surrendered.

                                                                            -98-

         (6) All Securities delivered for repurchase shall be delivered to the
Trustee to be canceled at the direction of the Trustee, which shall dispose of
the same as provided in Section 3.9.

SECTION 14.3 Certain Definitions.

         For purposes of this Article XIV,

outstanding shares of capital stock of the Company and (y) pursuant to which the
holders of 50% or more of the total voting power of all shares of the Company's
capital stock entitled to vote generally in the election of directors
immediately prior to such transaction have the entitlement to exercise, directly
or indirectly, 50% or more of the total voting power of all shares of capital
stock entitled to vote generally in the election of directors of the continuing

such transaction or (b) any transaction which is effected solely to change the
jurisdiction of incorporation of the Company and results in a reclassification,
conversion or exchange of outstanding shares of Common Stock into solely shares
of common stock); or

            (iii) during any period of two consecutive years, individuals who at
the beginning of such period constituted the Board of Directors (together with
any new directors whose election to the Board of Directors, or whose nomination
for election by the stockholders of the Company, was approved by a vote of a
majority of the directors then still in office who were either directors at the

previously approved) cease for any reason to constitute a majority of the Board
of Directors then in office (for the purposes of this paragraph, the term Board
of Directors shall not include any committee thereof).

            Provided, however, that a Change in Control shall not be deemed to
have occurred if the Closing Price Per Share of the Common Stock for any five
Trading Days within the period of 10

                                                                            -99-

and such shares constitute at the time such change or exchange becomes effective
in excess of 50% of the aggregate fair market value of such shares of stock and
other securities, property and assets (including cash) (as determined by the
Company, which determination shall be conclusive and binding), then the Person
formed by such consolidation or resulting from such merger or combination or
which acquires the properties or assets (including cash) of the Company, as the
case may be, shall execute and deliver to the Trustee a supplemental indenture
(which shall comply with the Trust Indenture Act as in force at the date of
