                                 NETEGRITY, INC.

                            2000 STOCK INCENTIVE PLAN

                         AS AMENDED AS OF AUGUST 8, 2001

         1.       PURPOSE OF THE PLAN.

         This stock incentive plan (the "Plan") is intended to provide
incentives: (a) to the employees of Netegrity, Inc. (the "Company") and any
present or future subsidiaries of the Company by providing them with
opportunities to purchase stock in the Company pursuant to options granted
hereunder which qualify as "incentive stock options" under Section 422 of the
Internal Revenue Code of 1986, as amended (the "Code") ("ISO" or "ISOs"); (b) to
officers, employees, consultants and directors of the Company and any present or
future subsidiaries by providing them with opportunities to purchase stock in
the Company pursuant to options granted hereunder which do not qualify as ISOs
("Non-Qualified Option" or "Non-Qualified Options"); and (c) to officers,
employees and consultants of the Company and any present or future subsidiaries
of the Company pursuant to stock awards. As used herein, the terms "parent" and
"subsidiary" mean "parent corporation" and "subsidiary corporation,"
respectively, as those terms are defined in Section 424 of the Code and the
Treasury Regulations promulgated thereunder (the "Regulations").

         2.       STOCK SUBJECT TO THE PLAN.

         (a)      The total number of shares of common stock, par value $.01 per
share, of the Company ("Common Stock") available for stock options and stock
awards granted under the Plan shall be 5,300,000 shares of Common Stock. The
maximum number of shares of Common Stock available for grants or awards under
this Plan shall be subject to adjustment in accordance with Section 12 hereof.
Shares issued under the Plan may be authorized but unissued shares of Common
Stock or shares of Common Stock held in treasury.

         (b)      To the extent that any stock option shall lapse, terminate,
expire or otherwise be cancelled without the issuance of shares of Common Stock,
or any stock award is settled in cash, the shares of Common Stock covered by
such option(s) or award shall again be available for the granting of stock
options or awards.

         (c)      Common Stock issuable under the Plan may be subject to such
restrictions on transfer, repurchase rights or other restrictions as shall be
determined by the Committee (as defined in Section 4 below).

<PAGE>

         3.       STOCK AWARDS.

         (a)      The Committee may grant, subject to the limitation on the
number of shares of Common Stock available under Section 2 hereof, stock awards
to employees of and other key individuals engaged to provide services to the
Company and its subsidiaries. A stock award may be made in stock or denominated
in stock subject to final settlement in cash or stock. Each stock award granted
shall be subject to such terms and conditions as the Committee, in its sole
discretion, shall determine and establish. These may include, but are not
limited to, establishing a holding period during which stock issued pursuant to
an award may not be transferred, requiring forfeiture of the stock award because
of termination of employment or failure to achieve specific objectives such as
measures of individual, business unit or Company performance, including stock
price appreciation. In determining a person's eligibility to be granted an
award, as well as in determining the number of shares to be awarded to any
person, the Committee shall take into account the person's position and
responsibilities, the nature and value to the Company or its subsidiaries of
such person's service and accomplishments, such person's present and potential
contribution to the success of the Company or its subsidiaries, and such other
factors as the Committee may deem relevant.

         (b)      The Committee may provide that a stock award shall earn
dividends or dividend equivalents, which may be paid currently or may be
deferred in payment, including reinvestment in additional shares covered by the
applicable stock award, all on such terms and conditions as the Committee shall
deem appropriate.

         (c)      The Committee shall require that for any stock award to be
effective, the recipient of the award shall execute an award agreement at such
time and in such form as the Committee shall determine. Any award agreement may
require that for any or some of the shares issued, the awardee must pay a
minimum consideration, whether in cash, property or services, as may be required
by applicable law or the Committee, as the Committee shall determine.

         (d)      A stock award may be granted singly or in combination or in
tandem with another stock award or stock option. A stock award may also be
granted as the payment form in settlement of a grant or right under any other
Company employee benefit or compensation plan, including the plan of an acquired
entity.

         (e)      Directors who are not otherwise employees of the Company or a
subsidiary shall not be eligible to receive stock awards pursuant to the Plan.

         (f)      No stock award granted to any person under the Plan shall be
assignable or transferable otherwise than by will or the laws of descent and
distribution. Any stock award granted under the Plan shall be null and void and

<PAGE>

without effect upon any attempted assignment or transfer, except as herein
provided, including without limitation any purported assignment, whether
voluntary or by operation of law, pledge, hypothecation or other disposition,
attachment, trustee process or similar process, whether legal or equitable, upon
such award.

         4.       ADMINISTRATION OF THE PLAN.

         (a)      At the discretion of the Company's Board of Directors, the
Plan shall be administered either (i) by the full Board of Directors of the
Company or (ii) by a committee (the "Committee") consisting of two or more
members of the Company's Board of Directors. In the event the full Board of
Directors is the administrator of the Plan, references herein to the Committee
shall be deemed to include the full Board of Directors. The Board of Directors
may from time to time appoint a member or members of the Committee in
substitution for or in addition to the member or members then in office and may
fill vacancies on the Committee however caused. The Committee shall choose one
of its members as Chairman and shall hold meetings at such times and places as
it shall deem advisable. A majority of the members of the Committee shall
constitute a quorum and any action may be taken by a majority of those present
and voting at any meeting.

         (b)      Any action may also be taken without the necessity of a
meeting by a written instrument signed by a majority of the Committee. The
decision of the Committee as to all questions of interpretation and application
of the Plan shall be final, binding and conclusive on all persons. The Committee
shall have the authority to adopt, amend and rescind such rules and regulations
as, in its opinion, may be advisable in the administration of the Plan. The
Committee may correct any defect or supply any omission or reconcile any
inconsistency in the Plan or in any option agreement granted hereunder in the
manner and to the extent it shall deem expedient to carry the Plan into effect
and shall be the sole and final judge of such expediency. No Committee member
shall be liable for any action or determination made in good faith.

         (c)      Subject to the terms of the Plan, the Committee shall have the
authority to (i) determine the employees of the Company and its subsidiaries
(from among the class of employees eligible under Section 5 to receive ISOs) to
whom ISOs may be granted, and to determine (from the class of individuals
eligible under Section 5 to receive Non-Qualified Options) to whom Non-Qualified
Options may be granted; (ii) determine the time or times at which options may be
granted; (iii) determine the option price of shares subject to each option which
price shall not be less than the minimum price specified in Section 7; (iv)
determine whether each option granted shall be an ISO or a Non-Qualified Option;
(v) determine (subject to Section 10) the time or times when each option shall
become exercisable and the duration of the exercise period; (vi) determine
whether restrictions such as repurchase options are to be imposed on shares

<PAGE>

subject to options and the nature of such restrictions; and (vii) determine the
size of any Options under the Plan, taking into account the position or office
of the optionee with the Company, the job performance of the optionee and such
other factors as the Committee may deem relevant in the good faith exercise of
its independent business judgment. Subject to the provisions of Section 3 the
Committee shall also have the authority to grant stock awards under this Plan.

         5.       ELIGIBILITY FOR GRANT OF OPTIONS.

         Options designated as ISOs may be granted only to employees of the
Company or any subsidiary. Non-Qualified Options may be granted to any officer,
employee, consultant or director of the Company or of any of its subsidiaries.

         In determining the eligibility of an individual to be granted an
option, as well as in determining the number of shares to be optioned to any
individual, the Committee shall take into account the position and
responsibilities of the individual being considered, the nature and value to the
Company or its subsidiaries of his or her service and accomplishments, his or
her present and potential contribution to the success of the Company or its
subsidiaries, and such other factors as the Committee may deem relevant.

         No option designated as an ISO shall be granted to any employee of the
Company or any subsidiary if such employee owns, immediately prior to the grant
of an option, stock representing more than 10% of the combined voting power of
all classes of stock of the Company or a parent or a subsidiary, unless the
purchase price for the stock under such option shall be at least 110% of its
fair market value at the time such option is granted and the option, by its
terms, shall not be exercisable more than five years from the date it is
granted. In determining the stock ownership under this paragraph, the provisions
of Section 424(d) of the Code shall be controlling. In determining the fair
market value under this paragraph, the provisions of Section 7 hereof shall
apply.

         The maximum number of shares of the Company's Common Stock with respect
to which an option or options may be granted to any employee in any calendar
year shall not exceed 500,000 shares, taking into account shares subject to
options granted and terminated, or repriced, during such calendar year, subject
to adjustment in accordance with Section 12.

         6.       OPTION AGREEMENT.

         Each option shall be evidenced by an option agreement (the "Agreement")
duly executed on behalf of the Company and by the optionee to whom such option
is granted, which Agreement shall comply with and be subject to the terms and
conditions of the Plan. The Agreement may contain such other terms, provisions
and conditions which are not inconsistent with the Plan as may be determined by

<PAGE>

the Committee. The date of grant of an option shall be as determined by the
Committee. More than one option may be granted to an individual.

         7.       OPTION PRICE.

         The option exercise price or prices of shares of the Company's Common
Stock for options designated as non-qualified stock options shall be determined
by the Committee, but in no event shall the option exercise price of a
non-qualified stock option be less than the fair market value of such Common
Stock at the time the option is granted. The option exercise price or prices of
shares of the Company's Common Stock for incentive stock options shall be no
less than the fair market value of such Common Stock at the time the option is
granted as determined by the Committee in accordance with Section 422 of the
Code and the Regulations promulgated thereunder.

         8.       MANNER OF PAYMENT; MANNER OF EXERCISE.

         (a)      The Agreement may provide for the payment of the exercise
price by delivery of (i) cash or a check payable to the order of the Company in
an amount equal to the exercise price of such options, (ii) shares of Common
Stock of the Company owned by the optionee having a fair market value equal in
amount to the exercise price of the options being exercised, or (iii) any
combination of (i) and (ii), provided, however, that payment of the exercise
price by delivery of shares of Common Stock of the Company owned by such
optionee may be made only if such payment does not result in a charge to
earnings for financial accounting purposes as determined by the Committee. The
fair market value of any shares of the Company's Common Stock which may be
delivered upon exercise of an option shall be determined by the Committee in
accordance with Section 7 hereof. With the consent of the Committee, delivery of
shares used to exercise any option may be made through attestation rather than
physical delivery of stock certificates. With the consent of the Committee,
payment may also be made by delivery of a properly executed exercise notice to
the Company, together with a copy of irrevocable instruments to a broker to
deliver promptly to the Company the amount of sale or loan proceeds to pay the
exercise price. To facilitate the foregoing, the Company may enter into
agreements for coordinated procedures with one or more brokerage firms.

         (b)      To the extent that the right to purchase shares under an
option has accrued and is in effect, options may be exercised in full at one
time or in part from time to time, by giving written notice, signed by the
person or persons exercising the option, to the Company, stating the number of
shares with respect to which the option is being exercised, accompanied by
payment in full for such shares as provided in subparagraph (a) above. Upon such
exercise, delivery of a certificate for paid-up non-assessable shares shall be
made at the principal office of the Company to the person or persons exercising
the option at such time, during ordinary business hours, not earlier than ten
business days

<PAGE>

from the date of receipt of the notice by the Company, as shall be designated in
such notice, or at such time, place and manner as may be agreed upon by the
Company and the person or persons exercising the option.

         9.       EXERCISE OF OPTIONS.

         Each option granted under the Plan shall, subject to the other
provisions of this Plan, be exercisable at such time or times and during such
period as shall be set forth in the Agreement.

         To the extent that an option to purchase shares is not exercised by an
optionee when it becomes initially exercisable, it shall not expire but shall be
carried forward and shall be exercisable, on a cumulative basis, until the
expiration of the exercise period. No partial exercise may be made for less than
two hundred fifty (250) full shares of Common Stock.

         10.      TERM OF OPTIONS; EXERCISABILITY.

         (a)      Term.

                  (1)      Each incentive stock option shall expire not more
         than seven (7) years from the date of the granting thereof, but shall
         be subject to earlier termination as herein provided.

                  (2)      Except as otherwise provided in this Section 10 or in
         the Optionee's Agreement, an option granted to any employee optionee
         who ceases to be an employee of the Company or one of its subsidiaries
         shall terminate on the 90th business day after the date such optionee
         ceases to be an employee of the Company or one of its subsidiaries, or
         on the date on which the option expires by its terms, whichever occurs
         first.

                  (3)      If such termination of employment is because of
         dismissal for cause or because the employee is in breach of any
         employment agreement, such option will terminate immediately on the
         date the optionee ceases to be an employee of the Company or one of its
         subsidiaries.

                  (4)      If such termination of employment is because the
         optionee has become permanently disabled (within the meaning of Section
         22(e)(3) of the Code), such option shall terminate on the last day of
         the twelfth month from the date such optionee ceases to be an employee,
         or on the date on which the option expires by its terms, whichever
         occurs first.

                  (5)      In the event of the death of any optionee, any option
         granted to such optionee shall terminate on the last day of the twelfth
         month from the date of death, or on the date on which the option
         expires by its terms, whichever occurs first.

<PAGE>

                  (6)      Notwithstanding subparagraphs (2), (3), (4) and (5)
         above, the Committee shall have the authority to extend the expiration
         date of any outstanding option in circumstances in which it deems such
         action to be appropriate, provided that no such extension shall extend
         the term of an option beyond the date on which the option would have
         expired if no termination of the optionee's employment had occurred.

         (b)      Exercisability.

                  (1)      An option granted to an employee optionee who ceases
         to be an employee of the Company or one of its subsidiaries shall be
         exercisable only to the extent that the right to purchase shares under
         such option has accrued and is in effect on the date such optionee
         ceases to be an employee of the Company or one of its subsidiaries.

                  (2)      In the event of the death of any optionee, the option
         granted to such optionee may be exercised by the estate of such
         optionee, or by any person or persons who acquired the right to
         exercise such option by bequest or inheritance or by reason of the
         death of such optionee.

         11.      TRANSFERABILITY.

         The right of any optionee to exercise any option granted to him or her
shall not be assignable or transferable by such optionee otherwise than by will
or the laws of descent and distribution, except that an optionee may transfer
options that are not ISOs granted under Plan to the optionee's spouse or
children or to a trust or partnership for the benefit of the optionee or the
optionee's spouse or children. ISOs shall be exercisable during the lifetime of
such optionee only by the optionee. Any option granted under the Plan shall be
null and void and without effect upon the bankruptcy of the optionee to whom the
option is granted, or upon any attempted assignment or transfer, except as
herein provided, including without limitation any purported assignment, whether
voluntary or by operation of law, pledge, hypothecation or other disposition,
attachment, divorce, trustee process or similar process, whether legal or
equitable, upon such option.

         12.      ADJUSTMENT FOR RECAPITALIZATIONS, REORGANIZATIONS AND OTHER
EVENTS.

         (a)      In the event that the outstanding shares of the Common Stock

of the Company are changed into or exchanged for a different number or kind of
shares or other securities of the Company or of another corporation by reason of
any reorganization, merger, consolidation, recapitalization, reclassification,
stock split-up, combination of shares, or dividends payable in capital stock,
appropriate adjustment shall be made in the number and kind of shares as to
which options and stock awards may be granted under the Plan and as to which

<PAGE>

outstanding options or awards or portions thereof then unexercised shall be
exercisable, to the end that the proportionate interest of the optionee or award
recipient shall be maintained as before the occurrence of such event; such
adjustment in outstanding options shall be made without change in the total
price applicable to the unexercised portion of such options and with a
corresponding adjustment in the option price per share.

         (b)      In addition, unless otherwise determined by the Committee in
its sole discretion, in the case of any (i) sale or conveyance to another entity
of all or substantially all of the property and assets of the Company or (ii)
Change in Control (as hereinafter defined) of the Company, the purchaser(s) of
the Company's assets or stock may, in his, her or its discretion, deliver to the
optionee the same kind of consideration that is delivered to the shareholders of
the Company as a result of such sale, conveyance or Change in Control, or the
Committee may cancel all outstanding options in exchange for consideration in
cash or in kind, which consideration in both cases shall be equal in value to
the value of those shares of stock or other securities the optionee would have
received had the option been exercised (to the extent then exercisable) and no
disposition of the shares acquired upon such exercise been made prior to such
sale, conveyance or Change in Control, less the option price therefor. Upon
receipt of such consideration by the optionee, his or her option shall
immediately terminate and be of no further force and effect. The value of the
stock or other securities the optionee would have received if the option had
been exercised shall be determined in good faith by the Committee of the
Company, and in the case of shares of the Common Stock of the Company, in
accordance with the provisions of Section 7 hereof. The Committee shall also
have the power and right to accelerate the exercisability of any options,
notwithstanding any limitations in this Plan or in the Agreement upon such a
sale, conveyance or Change in Control. Upon such acceleration, any options or
portion thereof originally designated as incentive stock options that no longer
qualify as incentive stock options under Section 422 of the Code as a result of
such acceleration shall be redesignated as non-qualified stock options. To the
extent permitted by law, upon such a sale, conveyance or a Change of Control the
Committee may, in its sole discretion, amend any Award Agreement issued under
the Plan in such manner as it deems appropriate, including without limitation,
by amendments that advance the dates upon which any or all outstanding awards
shall become free of restrictions or shall become issued or payable, or that
advance the dates upon which any or all outstanding awards shall terminate. For
purposes of the Plan, a "Change of Control" shall be deemed to have occurred if
any of the following conditions have occurred: (1) the merger or consolidation
of the Company with another entity where the Company is not the surviving entity
and where after the merger or consolidation (i) its stockholders prior to the
merger or consolidation hold less than 50% of the voting stock of the surviving
entity and (ii) its Directors prior to the merger or consolidation are less than
a majority of the Board of the surviving entity; (2) the sale of all or
substantially all of the Company's assets to a third party and subsequent to the

<PAGE>

transaction (i) its stockholders hold less than 50% of the stock of said third
party and (ii) its Directors are less than a majority of the Board of said third
party; or (3) a transaction or series of related transactions, including a
merger of the Company with another entity where the Company is the surviving
entity, whereby (i) 50% or more of the voting stock of the Company after the
transaction(s) is owned actually or beneficially by parties who held less than
thirty percent (30%) of the voting stock, actually or beneficially, prior to the
transaction(s) and (ii) its Board of Directors after the transaction(s) or
within sixty (60) days thereof, is comprised of less than a majority of the
Directors serving prior to the transaction(s).

         (c)      Upon dissolution or liquidation of the Company, all options
granted under this Plan shall terminate, but each optionee (if at such time in
the employ of or otherwise associated with the Company or any of its
subsidiaries) shall have the right, immediately prior to such dissolution or
liquidation, to exercise his or her option to the extent then exercisable. The
Committee shall have the right to accelerate the vesting of any award or take
such other action with respect thereto as the Committee shall in its sole
discretion determine in the event of any contemplated dissolution or liquidation
of the Company.

         (d)      No fraction of a share shall be purchasable or deliverable
upon the exercise of any option or stock award, but in the event any adjustment
hereunder of the number of shares covered by the option or award shall cause
such number to include a fraction of a share, such fraction shall be adjusted to
the nearest smaller whole number of shares.

         13.      NO SPECIAL EMPLOYMENT RIGHTS.

         Nothing contained in the Plan or in any option granted under the Plan
shall confer upon any option holder any right with respect to the continuation
of his employment by the Company (or any subsidiary) or interfere in any way
with the right of the Company (or any subsidiary), subject to the terms of any
separate employment agreement to the contrary, at any time to terminate such
employment or to increase or decrease the compensation of the option holder from
the rate in existence at the time of the grant of an option. Whether an
authorized leave of absence, or absence in military or government service, shall
constitute termination of employment shall be determined by the Committee at the
time.

         14.      WITHHOLDING.

         The Company's obligation to deliver shares upon settlement of an award
or upon the exercise of any option granted under the Plan, or to make any cash
payment in connection with an award, and any payments or transfers under Section
12 hereof, shall be subject to the option or award holder's satisfaction of all
applicable Federal, state, local and foreign governmental tax withholding

<PAGE>

requirements. Whenever cash is to be paid pursuant to an award under the Plan,
the Company shall be entitled to deduct therefrom an amount sufficient in its
opinion to satisfy all applicable tax withholding requirements related to such
payment. Whenever shares of Common Stock are to be delivered pursuant to an
award or the exercise of an option under the Plan, the Company shall be entitled
to require as a condition of delivery that the option or award holder remit to
the Company an amount sufficient in the opinion of the Company to satisfy all
applicable tax withholding requirements related thereto. With the approval of
the Committee, which it shall have sole discretion to grant, and on such terms
and conditions as the Committee may impose, the option or award holder may
satisfy the foregoing condition by electing to have the Company withhold from
delivery shares having a value equal to the amount of tax to be withheld. The
Committee shall also have the right to require that shares be withheld from
delivery to satisfy such condition. In the event that shares are used to satisfy
a tax withholding obligation under this Plan, the repurchased or withheld shares
shall not represent an amount in excess of the Company's minimum statutory tax
withholding obligation (based on minimum statutory withholding rates for federal
and state tax purposes, including payroll taxes, that are applicable to such
supplemental income).

         15.      RESTRICTIONS ON ISSUE OF SHARES.

         (a)      Notwithstanding the provisions of Section 8, the Company may
delay the issuance of shares covered by the exercise of an option and the
delivery of a certificate for such shares until the delivery or distribution of
any shares issued under this Plan complies with all applicable laws (including
without limitation, the Securities Act of 1933, as amended), and with the
applicable rules of any stock exchange upon which the shares of the Company are
listed or traded.

         (b)      It is intended that all exercises of options shall be
effective, and the Company shall use its best efforts to bring about compliance
with all applicable legal and regulatory requirements within a reasonable time,
except that the Company shall be under no obligation to qualify shares or to
cause a registration statement or a post-effective amendment to any registration
statement to be prepared for the purpose of covering the issue of shares in
respect of which any option may be exercised, except as otherwise agreed to by
the Company in writing.

         16.      LOANS.

<PAGE>

         The Company may not make loans to optionees to permit them to exercise
options.

         17.      MODIFICATION OF OUTSTANDING OPTIONS.

         The Committee may authorize the amendment of any outstanding option
with the consent of the optionee when and subject to such conditions as are
deemed to be in the best interests of the Company and in accordance with the
purposes of this Plan.

         18.      APPROVAL OF SHAREHOLDERS.

         The Plan shall take effect as of the date of adoption by the Board of
Directors. The Plan shall be submitted for approval by the vote of shareholders
holding at least a majority of the voting stock of the Company voting in person
or by proxy at a duly held shareholders' meeting, or by written consent of
shareholders holding at least a majority of the voting stock of the Company,
within twelve (12) months after the adoption of the Plan by the Board of
Directors. No options or awards granted on or after the next annual meeting of
the shareholders of the Company which occurs after approval of this Plan by the
Board of Directors shall take effect or be exercisable unless shareholder
approval is obtained in accordance with the previous sentence.

         19.      TERMINATION AND AMENDMENT.

         Unless sooner terminated as herein provided, the Plan shall terminate
ten (10) years from the date upon which the Plan was duly adopted by the Board
of Directors of the Company. The Board of Directors may at any time terminate
the Plan or make such modification or amendment thereof as it deems advisable;
provided, however, that the Board of Directors may not terminate, modify, or
amend the Plan without shareholder approval if such shareholder approval is
expressly required by applicable law. The Committee may terminate, amend or
modify any outstanding option without the consent of the option holder,
provided, however, that, except as provided in Section 12, without the consent
of the optionee, the Committee shall not change the number of shares subject to
an option, nor the exercise price thereof, nor extend the term of such option.

         20.      RESERVATION OF STOCK.

         The Company shall at all times during the term of the Plan reserve and
keep available such number of shares of stock as will be sufficient to satisfy
the

grants of Options or as issuances of Shares of Common Stock under the Plan,
shall be made pursuant to either (a) Section 102(b)(2) of the ITO as 102 Capital
Gains Track Grants or (b) Section 102(b)(1) of the ITO as 102 Ordinary Income
Track Grants. The Company's Election regarding the type of 102 Trustee Grant it
chooses to make must be filed with the ITA. Once the Company has filed such
Election, it may change the type of 102 Trustee Grant that it chooses to make
only after the passage of at least 12 months from the end of the calendar year
in which the first grant was made in accordance with the previous Election, in
accordance with Section 102. For the avoidance of doubt, such Election shall not
prevent the Company from granting Non-Trustee Grants.

         3.2      Eligible 102 Optionees may receive only 102 Trustee Grants or
Non-Trustee Grants. Optionees who are not Eligible 102 Optionees may be granted
only 3(I) Options under this Appendix.

         3.3      No 102 Trustee Grants may be made effective pursuant to this
Appendix until 30 days after the requisite filings required by the ITO and the
Rules have been made with the ITA.

         3.4      The option agreement or documents evidencing the Options
granted or Shares issued pursuant to the Plan and this Appendix shall indicate
whether the grant is a 102 Trustee Grant, a Non-Trustee Grant or a 3(I) Grant;
and, if the grant is a 102 Trustee Grant, whether it is a 102 Capital Gains
Track Grant or a 102 Ordinary Income Track Grant.

4. TERMS AND CONDITIONS OF 102 TRUSTEE OPTIONS

         4.1      Each 102 Capital Gains Track Grant will be deemed granted on
the date stated in a written notice by the Company, provided that on or before
such date (i) the Company has provided such notice to the Trustee and (ii) the
Optionee has signed all documents required pursuant to this Section 4.

         4.2      102 Trustee Grant Options granted to an Optionee during the
Required Holding Period shall be held in trust for the benefit of the Optionee
for the Required Holding Period, and each certificate for Shares acquired
pursuant to the exercise thereof or issued directly as a Shares during the
Required Holding Period shall be issued to and registered in the name of a
Trustee. After termination of the Required Holding Period, the Trustee may
release such Options and any such Shares, provided that (i) the Trustee has
received an acknowledgment from the Israeli Income Tax Authority that the
Optionee has paid any applicable tax due pursuant to the ITO or (ii) the Trustee
and/or the Company or its Affiliate withholds any applicable tax due pursuant to
the ITO. The Trustee shall not release any Options granted as 102 Trustee Grants
or Shares issued upon exercise of such Option prior to the full payment of the
Optionee's tax liabilities.

         4.3      Each 102 Trustee Grant (whether a 102 Capital Gains Track
Grant or a 102 Ordinary Income Track Grant, as applicable) shall be subject to
the relevant terms of Section 102 and the ITO, which shall be deemed an integral
part of the 102 Trustee Grant and which shall prevail over any term contained in
the Plan, this Appendix or the Option Agreement that is not consistent
therewith. Any provision of the ITO and any approvals by the Income Tax
Commissioner not expressly specified in the Plan, this Appendix or the Option
Agreement which are necessary to receive or maintain any tax benefit pursuant to
the Section 102 shall be binding on the Optionee. The Trustee and the Optionee
granted a 102 Trustee Grant shall comply with the ITO,

<PAGE>

and the terms and conditions of the Trust Agreement. For avoidance of doubt, it
is reiterated that compliance with the ITO specifically includes compliance with
the Rules. Further, the Optionee agrees to execute any and all documents which
the Company or the Trustee may reasonably determine to be necessary in order to
comply with the ITO and, particularly, the Rules.

         4.4      During the Required Holding Period, the Optionee shall not
require the Trustee to release or sell the Options or Shares and other shares
received subsequently following any realization of rights derived from Shares or
Options (including stock dividends) to the Optionee or to a third party, unless
permitted to do so by applicable law. Notwithstanding the foregoing, the Trustee
may, pursuant to a written request, release and transfer such Shares to the
Optionee or to a designated third party, provided that both of the following
conditions have been fulfilled prior to such transfer: (i) payment has been
rendered to the tax authorities of all taxes required to be paid upon the
release and transfer of the shares, and confirmation of such payment has been
received by the Trustee and (ii) the Trustee has received written confirmation
from the Company that all requirements for such release and transfer have been
fulfilled according to the terms of the Company's corporate documents, the Plan,
this Appendix and the Option Agreement and any applicable law. To avoid doubt,
such sale or release during the Required Holding Period will result in adverse
tax ramifications under Section 102 of the ITO and the Rules and/or any other
regulations or orders or procedures promulgated thereunder, which shall apply to
and shall be borne solely by such Optionee.

         4.5      In the event a stock dividend is declared on Shares which
derive from Options granted as 102 Trustee Grants, such dividend shall also be
subject to the provisions of this Section 4 and the Required Holding Period for
such dividend shares shall be measured from the commencement of the Required
Holding Period for the Option or Shares with respect to which the dividend was
declared.

         4.6      If an Option granted as a 102 Trustee Grant is exercised
during the Required Holding Period, the Shares issued upon such exercise shall
be issued in the name of the Trustee for the benefit of the Optionee. If such an
Option is exercised after the Required Holding Period ends, the Shares issued
upon such exercise shall, at the election of the Optionee, either (i) be issued
in the name of the Trustee, or (ii) be transferred to the Optionee directly,
provided that the Optionee first complies with all applicable provisions of the
Plan.

5. ASSIGNABILITY

         As long as Options or Shares are held by the Trustee on behalf of the
Eligible 102 Optionee, all rights of the Eligible 102 Optionee over the shares
are personal, can not be transferred, assigned, pledged or mortgaged, other than
by will or laws of descent and distribution.

6. TAX CONSEQUENCES

         6.1      Any tax consequences arising from the grant or exercise of any
Option, from the payment for Shares covered thereby, or from any other event or
act (of the Company, and/or its Affiliates, and the Trustee or the Optionee),
hereunder, shall be borne solely by the Optionee, with the exception of taxes
imposed upon the Company or its Affiliate by law, such as the employer's
component of payments to the National Insurance Institute. The Company and/or
its Affiliates, and/or the Trustee shall withhold taxes according to the
requirements under the applicable laws, rules, and regulations, including
withholding taxes at source. Furthermore, the Optionee shall agree to indemnify
the Company and/or its affiliates and/or the Trustee and hold them harmless
against and from any and all liability for any such tax or interest or penalty
thereon, including without limitation, liabilities relating to the necessity to
withhold, or to have withheld, any such tax from any payment made to the
Optionee for which the Optionee is responsible, including specifically any
additional tax liability the Company may incur as a result of the exercise of
Options or any transfer effected prior to conclusion of the applicable Required
Holding Period. The Company or any of its Affiliates and the

<PAGE>

Trustee may make such provisions and take such steps as it/they may deem
necessary or appropriate for the withholding of all taxes required by law to be
withheld with respect to Options granted under the Plan and the exercise
thereof, including, but not limited to (i) deducting the amount so required to
be withheld from any other amount then or thereafter payable to a Optionee,
and/or (ii) requiring a Optionee to pay to the Company or any of its Affiliates
the amount so required to be withheld as a condition of the issuance, delivery,
distribution or release of any Shares. In addition, the Optionee will be
required to pay any amount that exceeds the tax to be withheld and transferred
to the tax authorities, pursuant to applicable Israeli tax laws and regulations.

         6.2      With respect to Non-Trustee Grants, if the Optionee ceases to
be employed by the Company or any Affiliate, the Optionee shall extend to the
Company and/or its Affiliate a security or guarantee for the payment of tax due
at the time of sale of Shares, all in accordance with the provisions of Section
102 of the ITO and the Rules.

7. GOVERNING LAW AND JURISDICTION

Notwithstanding any other provision of the Plan, with respect to Optionees
subject to this Appendix, the Plan and all instruments issued thereunder or in
connection therewith shall be governed by, and interpreted in accordance with,
the laws of the State of Israel applicable to contracts made and to be performed
therein.<PAGE>

         This Pooling and Servicing Agreement (this "Agreement") is dated and
effective as of January 12, 2004, among STRUCTURED ASSET SECURITIES CORPORATION
II, as Depositor, WACHOVIA BANK, NATIONAL ASSOCIATION, as Master Servicer,
LENNAR PARTNERS, INC., as Special Servicer, LASALLE BANK NATIONAL ASSOCIATION,
as Trustee, and ABN AMRO BANK N.V., as Fiscal Agent.

                             PRELIMINARY STATEMENT:

         The Depositor intends to sell the Certificates, which are to be issued
hereunder in multiple Classes and which in the aggregate will evidence the
entire beneficial ownership interest in the Trust Fund.

         As provided herein, the Trustee will elect to treat the segregated pool
of assets consisting of the Trust Mortgage Loans (exclusive of any collections
of Additional Interest on the ARD Trust Mortgage Loans after their respective
Anticipated Repayment Dates) and certain other related assets subject to this
Agreement as a REMIC for federal income tax purposes, and such segregated pool
of assets will be designated as "REMIC I". The Class R-I Certificates will
represent the sole class of "residual interests" in REMIC I for purposes of the
REMIC Provisions under federal income tax law. A separate REMIC I Regular
Interest will, on the Closing Date, be issued with respect to, and will
thereafter relate to, each Trust Mortgage Loan in REMIC I. Each REMIC I Regular
Interest issued with respect to, and relating to, a Trust Mortgage Loan, shall
also relate to any successor REO Trust Mortgage Loan with respect to such Trust
Mortgage Loan. Each REMIC I Regular Interest shall (i) bear a numeric
designation that is the same as the loan number for the related Trust Mortgage
Loan set forth on the Trust Mortgage Loan Schedule, (ii) accrue interest at a
per annum rate described in the definition of "REMIC I Remittance Rate" and
(iii) have an initial Uncertificated Principal Balance equal to the Cut-off Date
Balance of the related Trust Mortgage Loan. The Legal Final Distribution Date of
each of the REMIC I Regular Interests is the Distribution Date immediately
following the third anniversary of the end of the remaining amortization term
(as determined as of the Closing Date) of the related Trust Mortgage Loan. None
of the REMIC I Regular Interests will be certificated.

         As provided herein, the Trustee will elect to treat the segregated pool
of assets consisting of the REMIC I Regular Interests as a REMIC for federal
income tax purposes, and such segregated pool of assets will be designated as
"REMIC II". The Class R-II Certificates will represent the sole class of
"residual interests" in REMIC II for purposes of the REMIC Provisions under
federal income tax law. The following table sets forth the designation, the
REMIC II Remittance Rate and the initial Uncertificated Principal Balance for
each of the REMIC II Regular Interests. The Legal Final Distribution Date for
each REMIC II Regular Interest is the latest Rated Final Distribution Date. None
of the REMIC II Regular Interests will be certificated.

    (1)  The REMIC II Remittance Rate in effect for any REMIC II Regular
         Interest (other than REMIC II Regular Interest X-ST) during any
         Interest Accrual Period shall equal the Weighted Average REMIC I
         Remittance Rate for such Interest Accrual Period.

   (2)   REMIC II Regular Interest X-ST will not have an Uncertificated
         Principal Balance and will not entitle REMIC III as the holder thereof
         to any deemed distributions of principal. As more specifically provided
         herein, interest in respect of REMIC II Regular Interest X-ST will be
         calculated based on its fixed REMIC II Remittance Rate and an
         Uncertificated Notional Amount equal to the Uncertificated Principal
         Balance of the REMIC I Regular Interest issued in respect of the UBS
         Center Trust Mortgage Loan.

         As provided herein, the Trustee will elect to treat the segregated pool
of assets consisting of the REMIC II Regular Interests as a REMIC for federal
income tax purposes, and such segregated pool of assets will be designated as
"REMIC III". The Class R-III Certificates will evidence the sole class of
"residual interests" in REMIC III for purposes of the REMIC Provisions under
federal income tax law. The following table irrevocably sets forth the Class
designation, Pass-Through Rate and original Class Principal Balance for each
Class of the Regular Interest Certificates. For federal income tax purposes,
each Class of the Regular Interest Certificates (exclusive of the Class X-CL and
Class X-CP Certificates), each of the 29 REMIC III Components of the Class X-CL
Certificates and each of the

separate "regular interest" in REMIC III. The Legal Final Distribution Date for
each Class of Regular Interest Certificates (exclusive of the Class X-CL and
Class X-CP Certificates), for each of the 29 REMIC III Components of the Class
X-CL Certificates and for each of the 17 REMIC III Components of the Class X-CP
Certificates is the latest Rated Final Distribution Date.

         Class N, Class P, Class Q, Class S, Class T, Class X-CL and Class X-CP
         Certificates will, in the case of each of those Classes, be a variable
         rate per annum calculated in accordance with the definition of
         "Pass-Through Rate".

(2)      The Class X-CL Certificates will not have a Class Principal Balance and
         will not entitle their Holders to receive distributions of principal.
         The Class X-CL Certificates will have a Class Notional Amount which
         will be equal to the aggregate of the Component Notional Amounts of the
         Class X-CL REMIC III Components from time to time. As more specifically

         will not entitle their Holders to receive distributions of principal.
         As more specifically provided herein, interest in respect of the Class
         X-ST Certificates will be calculated based upon their fixed
         Pass-Through Rate (which will be the same as the REMIC II Remittance
         Rate for REMIC II Regular Interest X-ST) and their Class Notional
         Amount from time to time (which will be the same as the Uncertificated
         Notional Amount of REMIC II Regular Interest X-ST from time to time).

         As provided herein, the Trustee shall take all actions necessary to
ensure that the portion of the Trust Fund consisting of the Grantor Trust Assets

time to time with respect to any Class of Regular Interest Certificates, the
amount of which interest shall equal: (a) in the case of any Class of Principal

Interest Accrual Period, multiplied by (ii) the Class Principal Balance of such
Class of Certificates outstanding immediately prior to the related Distribution

with respect to REMIC II Regular Interest X-ST for such Interest Accrual Period

         "Accrued Component Interest" shall mean the interest accrued from time

be deferred until the entire outstanding principal balance thereof has been
paid). For purposes of this Agreement, Additional Interest on an ARD Mortgage
Loan or any successor REO Mortgage Loan with respect thereto shall be deemed not
to constitute principal or any portion thereof and shall not be added to the
unpaid principal balance or Stated Principal Balance of such ARD Mortgage Loan
or any successor REO Mortgage Loan with respect thereto, notwithstanding that
the terms of the related loan documents so permit. To the extent that any
Additional Interest is not paid on a current basis, it shall, for purposes of

may be, in the Holders of Regular Interest Certificates receiving less than the
full amount of principal and/or Distributable Certificate Interest to which they
are entitled on any Distribution Date.

         "Adjusted Actual/360 Accrued Interest Amount" shall mean, with respect
to any REMIC I Regular Interest that relates to an Interest Reserve Mortgage

Loan as of the Closing Date (without regard to any modifications, extensions,
waivers or amendments of the related Trust Mortgage Loan subsequent to the
Closing Date), multiplied by (b) a fraction, the numerator of which is the
number of days in such Interest Accrual Period, and the denominator of which is
360, multiplied by (c) the Uncertificated Principal Balance of such REMIC I
Regular Interest immediately prior to the Distribution Date that corresponds to
such Interest Accrual Period; provided that, if the subject Interest Accrual
Period ends during (x) January of 2005 or any year thereafter that is not a leap
year or (y) February of 2004 or any year thereafter, then the amount of interest

Amount(s), if any, with respect to the related Interest Reserve Mortgage Loan or
Interest Reserve REO Mortgage Loan, as the case may be, transferred (in
accordance with Section 3.05(c)) from the Interest Reserve Account to the
Collection Account in the calendar month in which such Interest Accrual Period
ends.

         "Adjusted Actual/Actual Accrued Interest Amount" shall mean, with
respect to any REMIC I Regular Interest that relates to an Interest Reserve
Mortgage Loan or an Interest Reserve REO Mortgage Loan that accrues interest on
an Actual/Actual Basis, for any Interest Accrual Period, an amount of interest
equal to the product of (a) the Mortgage Rate in effect for the related Trust
Mortgage Loan as of the Closing Date (without regard to any modifications,
extensions, waivers or amendments of the related Trust Mortgage Loan subsequent
to the Closing Date), multiplied by (b) a fraction, the numerator of which is

mean that the relevant decision regarding the release of collateral or the

         case of an MGM Tower Mortgage Loan), the GIC Office Controlling Party
         (in the case of a GIC Office Mortgage Loan) or the Controlling Class
         Representative (in the case of any other Mortgage Loan), as applicable,
         for such 30-day forbearance in deeming such Mortgage Loan a "Specially
         Serviced Mortgage Loan" under clause (A) above), or (C) if clause (B)
         above otherwise applies and, before the end of the 30-day period

         Loan, including a Balloon Payment, is likely to occur and is likely to
         remain unremedied (without regard to any grace period) by the related
         Mortgagor, any related guarantor or otherwise (including, in the case
         of a GIC Office Note A Mortgage Loan, by the GIC Office Subordinate

         Serviced Mortgage Loan" pursuant to this paragraph (b) if, with respect
         to such event, the Master Servicer has determined (subject to Section
         6.11, Section 6.12 and/or Section 6.13 in each case if and as
         applicable) that the Master Servicer's granting of a six-month
         extension of the maturity date of the subject Mortgage Loan (subject to
         a limit of two such six-month extensions for the subject Five-Year
         Mortgage Loan) is in accordance with the Servicing Standard, and at
         such time no other circumstance identified in clauses (a) through (g)
         of this definition exists that would cause such Mortgage Loan to be
         characterized as a Specially Serviced Mortgage Loan; or

                  (c) there shall have occurred a default (other than as
         described in clause (a) above and other than an Acceptable Insurance
         Default) that (i) materially impairs the value of the related Mortgaged
         Property as security for such Mortgage Loan or otherwise materially
         adversely affects the interests of Certificateholders (or, in the case
         of a Non-Trust Mortgage Loan, the related Non-Trust Mortgage Loan
         Noteholder), and (ii) continues unremedied by the related Mortgagor,
         any related guarantor or otherwise (including in the case of a GIC
         Office Note A Mortgage Loan, by the GIC Office Subordinate Non-Trust
         Mortgage Loan Noteholder exercising GIC Office Cure Rights or, in the
         case of the MGM Tower Trust Mortgage Loan, by the MGM Tower Non-Trust
         Mortgage Loan Noteholder exercising MGM Tower Cure Rights) for either
         (A) one Business Day (but only if, pursuant to the related loan
         documents, the subject default gives rise to immediate acceleration
         without application of a cure period under such Mortgage Loan) or (B)

         terms of such Mortgage Loan (plus, solely in the case of any GIC Office
         Mortgage Loan or MGM Tower Mortgage Loan, if applicable, the applicable
         cure period for exercising GIC Office Cure Rights or MGM Tower Cure
         Rights, as applicable, under the terms of the related Co-Lender
         Agreement) and (2) 30 days; and provided, further, that,
         notwithstanding the immediately preceding proviso, in the case of a
         default that relates to the failure by the related Mortgagor to
         maintain either all risk insurance that covers acts of terrorism or a
         separate insurance policy that covers acts of terrorism and, as to
         which the failure to maintain such insurance has been determined by the
         Special Servicer not to constitute an "Acceptable Insurance Default",
         such default must continue unremedied for a period of at least 30 days
         beyond such determination by the Special Servicer; or

                  (d) 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, marshaling of
         assets and liabilities or similar proceedings, or for the winding-up or
         liquidation of its affairs, shall have been entered against the related
         Mortgagor and such decree or order shall have remained in force and not
         dismissed for a period of 60 days; or

                  (e) the related Mortgagor shall consent to the appointment of
         a conservator or receiver or liquidator in any insolvency, readjustment
         of debt, marshaling of assets and liabilities or similar proceedings of
         or relating to such Mortgagor or of or relating to all or substantially
         all of its property; or

                  (f) the related Mortgagor 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; or

                  (g) the Master Servicer shall have received notice of the
         commencement of foreclosure or similar proceedings with respect to the
         related Mortgaged Property;

provided, however, that a Mortgage Loan will cease to be a Specially Serviced
Mortgage Loan when a Liquidation Event has occurred with respect to such
Mortgage Loan, when the related Mortgaged Property has become an REO Property
or, so long as at such time no circumstance identified in clauses (a) through
(g) above exists that would cause such Mortgage Loan to continue to be
characterized as a Specially Serviced Mortgage Loan, when:

          (w)     with respect to the circumstances described in clause (a) of
                  this definition, the related Mortgagor has made three
                  consecutive full and timely Monthly Payments under the terms
                  of such Mortgage Loan (as such terms may be changed or
                  modified in connection with a bankruptcy or similar proceeding
                  involving the related Mortgagor or by reason of a
                  modification, extension, waiver or amendment granted or agreed
                  to by the Master Servicer or the Special Servicer pursuant to
                  Section 3.20);

          (x)     with respect to the circumstances described in clauses (b),
                  (d), (e) and (f) of this definition, such circumstances cease
                  to exist in the good faith, reasonable judgment of the Special
                  Servicer, but, with respect to any bankruptcy or insolvency
                  proceedings described in clauses (d), (e) and (f), no later
                  than the entry of an order or decree dismissing such
                  proceeding;

          (y)     with respect to the circumstances described in clause (c) of
                  this definition, such default is cured as determined by the
                  Special Servicer in its reasonable, good faith judgment; and

          (z)     with respect to the circumstances described in clause (g) of
                  this definition, such proceedings are terminated.

         The Special Servicer may conclusively rely on the Master Servicer's
determination as to whether a Servicing Transfer Event has occurred giving rise
to a Mortgage Loan's becoming a Specially Serviced Mortgage Loan. If any
Mortgage Loan that is part of a Loan Combination becomes a Specially Serviced
Mortgage Loan, then the other Mortgage Loan or each of the other Mortgage Loans,
as the case may be, in such Loan Combination shall also become a Specially
Serviced Mortgage Loan; provided that if a GIC Office Subordinate Non-Trust
Mortgage Loan Noteholder prevents the occurrence of a Servicing Transfer Event
with respect to the GIC Office Note A Mortgage Loans through the exercise of GIC
Office Cure Rights with respect to such GIC Office Note A Mortgage Loans, then
the existence of such Servicing Transfer Event with respect to the GIC Office
Subordinate Non-Trust Mortgage Loan (because GIC Office Cure Rights do not
include the cure of defaults under the GIC Office Subordinate Non-Trust Mortgage
Loan) will not, in and of itself, result in any of the GIC Office Mortgage Loans
becoming a Specially Serviced Mortgage Loan unless a separate Servicing Transfer
Event has occurred with respect thereto; and provided, further, that if the MGM
Tower Non-

<PAGE>

Trust Mortgage Loan Noteholder prevents the occurrence of a Servicing Transfer
Event with respect to the MGM Tower Trust Mortgage Loan through the exercise of
MGM Tower Cure Rights with respect to the MGM Tower Trust Mortgage Loan, then
the existence of such Servicing Transfer Event with respect to the MGM Tower
Non-Trust Mortgage Loan (because MGM Tower Cure Rights do not include the cure
of defaults under the MGM Tower Non-Trust Mortgage Loan) will not, in and of
itself, result in either of the MGM Tower Mortgage Loans becoming a Specially
Serviced Mortgage Loan unless a separate Servicing Transfer Event has occurred
with respect thereto; and provided, further, that no defeased GIC Office
Mortgage Loan shall become a Specially Serviced Mortgage Loan solely by reason
of a non-defeased GIC Office Mortgage Loan's becoming a Specially Serviced
Mortgage Loan or solely by reason of the operation of the cross-default
provisions of such defeased GIC Office Mortgage Loan in connection with a
default under a non-defeased GIC Office Mortgage Loan.

similar proceeding involving the related Mortgagor or a modification, extension,

the Principal Distribution Amount for such Distribution Date allocable to such
Trust Mortgage Loan (or any such successor REO Trust Mortgage Loan with respect
thereto), without giving effect to any adjustments pursuant to Section 1.03 in
connection with the calculation of Adjusted Principal Distribution Amount, and
(ii) the principal portion of any Realized Loss incurred in respect of such
Trust Mortgage Loan (or any such successor REO Trust Mortgage Loan with respect
thereto) (without duplication of any previous reduction to the Stated Principal
Balance of such Trust Mortgage Loan under clause (i) above based on an Advance
of any amount that constitutes part of such principal portion of such Realized
Loss); and (b) with respect to any Non-Trust Mortgage Loan (and any successor
REO Mortgage Loan with respect thereto), the Cut-off Date Balance of such
Non-Trust Mortgage Loan, as permanently reduced on each related Master Servicer

respect thereto) distributed to the related Non-Trust Mortgage Loan Noteholder
on such Master Servicer Remittance Date, and (ii) the principal portion of any
Realized Loss incurred in respect of such Non-Trust Mortgage Loan (or any such
successor REO Mortgage Loan with respect thereto) in connection with a

of any Mortgage Loan or REO Property, then the "Stated Principal Balance" of
such Mortgage Loan or of the

                                      -82-

Remittance Date) in the applicable Collection Period next following the
applicable Collection Period in which such Liquidation Event occurred.

         "Subordinate Available Distribution Amount" shall mean, with respect to

         "Workout Fee" shall mean the fee designated as such in, and payable to
the Special Servicer with respect to certain collections on each Corrected
Mortgage Loan pursuant to, Section 3.11(c).

         "Workout Fee Rate" shall mean, with respect to each Corrected Mortgage
Loan as to which a Workout Fee is payable, 1.0%.

         "Yield Maintenance Charge" shall mean the payments paid or payable, as
the context requires, as the result of a Principal Prepayment on, or other early
collection of principal of, a Mortgage Loan, which payments are not otherwise
due thereon in respect of principal or interest and have been calculated (based
on scheduled payments of interest and/or principal on such Mortgage Loan) to
compensate the holder for reinvestment losses based on the value of an interest
rate index at or near the time of prepayment. Any other prepayment premiums,
penalties and fees not so calculated will not be considered "Yield Maintenance
Charges". In the event that a Yield Maintenance Charge shall become due for any
particular Mortgage Loan, the Master Servicer shall be required to follow the
terms and provisions contained in the applicable Mortgage Note, provided,
however, in the event the particular Mortgage Note shall not specify the U.S.
Treasuries which shall be used in determining the discount rate

                                      -88-
<PAGE>

or the reinvestment yield to be applied in such calculation, the Master Servicer
shall be required to use those U.S. Treasuries which shall generate the lowest
discount rate or reinvestment yield for the purposes thereof. Accordingly, if
either no U.S. Treasury issue, or more than one U.S. Treasury issue, shall
coincide with the term over which the Yield Maintenance Charge shall be
calculated (which depending on the applicable Mortgage Note is based on the
remaining average life of the Mortgage Loan or the actual term remaining through
the related Stated Maturity Date or Anticipated Repayment Date, as applicable),
the Master Servicer shall use the applicable U.S. Treasury whose reinvestment
yield is the lowest, with such yield being based on the bid price for such issue
as published in The Wall Street Journal on the date that is 14 days prior to the
date that the Yield Maintenance Charge shall become due and payable (or, if such
bid price is not published on that date, the next preceding date on which such
bid price is so published) and converted to a monthly compounded nominal yield.
The monthly compounded nominal yield ("MEY") is derived from the reinvestment
yield or discount rate and shall be defined as MEY = (12 X [{(1+ "BEY"/2)
^1/6}-1]) X 100, where BEY is defined as the U.S. Treasury Reinvestment Yield
which is in decimal form and not in percentage, and 1/6 is the exponential power
to which a portion of the equation is raised. For example, using a BEY of 5.50%,
the MEY = (12 X [{(1+ .055/2) ^ 0.16667}- 1]) X 100 where .055 is the decimal
version of the percentage 5.5% and 0.16667 is the decimal version of the
exponential power. The MEY in the above calculation is 5.44%.

         "Yield Maintenance Treasury Rate" shall mean, for purposes of
calculating a Discount Rate:

         (1)      with respect to any Mortgage Loan other than the Grogan's Mill
                  Office Trust Mortgage Loan and the Borough Park Portfolio
                  Trust Mortgage Loan, the yield calculated by the Master
                  Servicer by linear interpolation of the yields, as such yields
                  are reported in Federal Reserve Statistical Release
                  H.15-Selected Interest Rates (519), under the heading U.S.
                  Government Securities/Treasury Constant Maturities, with
                  respect to the maturity dates set forth thereunder, one longer
                  and one shorter, most nearly approximating the maturity date
                  (or, in the case of an ARD Trust Mortgage Loan or any
                  successor REO Trust Mortgage Loan with respect thereto, the
                  Anticipated Repayment Date) of the relevant prepaid Trust
                  Mortgage Loan or REO Trust Mortgage Loan; and

         (2)      with respect to the Grogan's Mill Office Trust Mortgage Loan
                  and the Borough Park Portfolio Trust Mortgage Loan,
                  respectively, the lesser of: (a) either (i) the yield on the
                  U.S. Treasury issue (primary issue) with the same maturity
                  date as the maturity date of the relevant prepaid Trust
                  Mortgage Loan or REO Trust Mortgage Loan, or (ii) if no such
                  U.S. Treasury issue is available, then the interpolated yield
                  on the two U.S. Treasury issues (primary issues) with maturity
                  dates (one longer and one shorter), most nearly approximating
                  the maturity date of the relevant prepaid Trust Mortgage Loan
                  or REO Trust Mortgage Loan, and (b) either (i) the yield on
                  the U.S. Treasury issue (primary issue) with a term equal to
                  the remaining average life of the relevant prepaid Trust
                  Mortgage Loan or REO Trust Mortgage Loan, or (ii) if no such
                  U.S. Treasury issue is available, then the interpolated yield
                  on the two U.S. Treasury issues (primary issues) with terms
                  (one longer and one shorter) that most nearly approximate the
                  remaining average life of the relevant prepaid Trust Mortgage
                  Loan or REO Trust Mortgage Loan, with each such yield being
                  based on the bid price for such issue as published in

                                      -89-
<PAGE>

                  The Wall Street Journal on the date that is 14 days prior to
                  the prepayment date set forth in the related Mortgagor's
                  prepayment notice (or, if such bid price is not published on
                  that date, the next preceding date on which such bid price is
                  so published).

In the event either the Federal Reserve Statistical Release H.15 (referred to in
clause (1) of this definition) or The Wall Street Journal (referred to in clause
(2) of this definition) is no longer published or does not indicate the related
information set forth above, the Master Servicer shall, in lieu of the
applicable publication or source, select a comparable publication or source for
the purposes of determining the Yield Maintenance Treasury Rate.

         "YM Principal Balance Certificates" shall mean, collectively, the Class
A-1, Class A-2, Class A-3, Class A-4, Class B, Class C, Class D, Class E, Class
F, Class G, Class H, Class J and Class K Certificates.

         SECTION 1.02. General Interpretive Principles.

         For purposes of this Agreement, except as otherwise expressly provided

         SECTION 1.03. Certain Adjustments to the Principal Distributions on
                       the Certificates.

         (a) If any party hereto is reimbursed out of general collections on the
Mortgage Pool on deposit in the Pool Custodial Account for any unreimbursed
Advances that have been or are determined to be Nonrecoverable Advances
(together with interest accrued and payable thereon pursuant to Section 3.11(g)
or Section 4.03(d), as applicable, to the extent such interest was paid
hereunder from a source other than related Default Charges), then (for purposes
of calculating distributions on the Certificates) each such reimbursement and
payment of interest shall be deemed to have been made:

                  first, out of any amounts then on deposit in the Pool
         Custodial Account that represent payments or other collections of
         principal received with respect to the Mortgage Pool that, but for
         their application to reimburse a Nonrecoverable Advance and/or to pay
         interest thereon, would be included in the Available Distribution
         Amount for the related Distribution Date;

                  second, out of any amounts then on deposit in the Pool
         Custodial Account that represent any other payments or other
         collections received with respect to the Mortgage Pool that, but for
         their application to reimburse a Nonrecoverable Advance and/or to pay
         interest thereon, would be included in the Available Distribution
         Amount for the related Distribution Date; and

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

         (b) If and to the extent that any payment or other collection of
principal of any Trust Mortgage Loan or REO Trust Mortgage Loan is deemed to be
applied in accordance with clause first of Section 1.03(a) to reimburse a
Nonrecoverable Advance or to pay interest thereon, and further if and to the
extent that such payment or other collection of principal constitutes part of
the Principal Distribution Amount for any Distribution Date, then: (i) the
Adjusted Principal Distribution Amount for such Distribution Date shall exclude
such payment or other collection of principal; and (ii) for purposes of
calculating the Adjusted Principal Distribution Amount for such Distribution
Date, the amount of such payment or other collection of principal shall be
subtracted from the Principal Distribution Amount for such Distribution Date.

         (c) If and to the extent that (1) any Advance is determined to be a
Nonrecoverable Advance, (2) such Advance is reimbursed or interest thereon is
paid out of general principal collections on the Mortgage Pool as contemplated
by Section 1.03(a) above and (3) the particular item for which such Advance was
originally made or such interest on such Advance, as the case may be, is
subsequently collected (in whole or in part) out of payments or other
collections in respect of the related Trust Mortgage Loan or REO Trust Mortgage
Loan (such item or such interest on such Advance, as the case may be, if and to
the extent so collected, a "Recovered Amount"), then: (i) without duplication of
any amounts already included therein, the Adjusted Principal Distribution Amount
for the Distribution Date that corresponds to the Collection Period in which
such item or such interest on such Advance, as the case may be, was recovered
shall include such Recovered Amount; (ii) for purposes of calculating the
Adjusted Principal Distribution Amount for the Distribution Date that
corresponds to the Collection Period in which such item was recovered, such
Recovered Amount (to the extent not already included therein) shall be added to
the Principal Distribution Amount for such Distribution Date; and (iii) such
Advance or such interest thereon, as the case may be, to the extent of such
Recovered Amount, will no longer be considered to have been reimbursed or paid,
as the case may be, out of general principal

                                      -91-
<PAGE>

collections on the Mortgage Pool. In addition, if and to the extent that any
Advance is determined to be a Nonrecoverable Advance, interest on such Advance
is paid out of general principal collections on the Mortgage Pool as
contemplated by Section 1.03(a) above and such interest on such Advance is
subsequently reimbursed to the Trust out of Default Charges collected on the
Trust Mortgage Loan or REO Trust Mortgage Loan as to which such Advance was
made, then: (i) the Adjusted Principal Distribution Amount for the Distribution
Date that corresponds to the Collection Period in which such Default Charges
were recovered shall include the portion of such Default Charges that was
applied to reimburse the Trust for such interest on such Advance; (ii) for
purposes of calculating the Adjusted Principal Distribution Amount for the
Distribution Date that corresponds to the Collection Period in which such
Default Charges were recovered, an amount equal to the portion of such Default
Charges that was applied to reimburse the Trust for such interest on such
Advance shall be added to the Principal Distribution Amount for such
Distribution Date; and (iii) such interest on such Advance, to the extent of
such Recovered Amount, will no longer be considered to have been paid out of
general principal collections on the Mortgage Pool

         (d) Nothing contained in this Section 1.03 is intended to limit the
ability of any party hereto that is entitled to reimbursement hereunder for any
unreimbursed Advances that have been or are determined to be Nonrecoverable
Advances (together with interest accrued and payable thereon pursuant to Section
3.11(g) or Section 4.03(d)) to collections of principal received with respect to
the Mortgage Pool; instead the order of priority set forth in Section 1.03(a) is
a deemed allocation only for purposes of calculating distributions on the
Certificates.

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

         SECTION 2.01. Creation of Trust; Conveyance of Trust Mortgage Loans.

         (a) It is the intention of the parties hereto that a common law trust
be established pursuant to this Agreement and that such trust be designated as
"LB-UBS Commercial Mortgage Trust 2004-C1". LaSalle is hereby appointed, and
does hereby agree, to act as Trustee hereunder and, in such capacity, to hold
the Trust Fund in trust for the exclusive use and benefit of all present and
future Certificateholders.

         The Depositor, concurrently with the execution and delivery hereof,
does hereby assign, sell, transfer, set over and otherwise convey to the Trustee
in trust, without recourse, for the benefit of the Certificateholders, all the
right, title and interest of the Depositor in, to and under (i) the Trust
Mortgage Loans, (ii) the UBS/Depositor Mortgage Loan Purchase Agreement, (iii)
the MGM Tower Co-Lender Agreement, (iv) the GIC Office Co-Lender Agreement, and
(v) all other assets included or to be included in the Trust Fund. Such
assignment includes all interest and principal received or receivable on or with
respect to the Trust Mortgage Loans and due after the Cut-off Date and, in the
case of each of the GIC Office Trust Mortgage Loan and the MGM Tower Trust
Mortgage Loan, is subject to the provisions of the related Co-Lender Agreement.
The Trustee, on behalf of the Trust, assumes the obligations of the "Note A
Lender" under the MGM Tower Co-Lender Agreement and the obligations of the
"Controlling Note A-1 Lender" (and any other obligations of the holder of the
GIC Office Trust Mortgage Loan) under the GIC Office Co-Lender Agreement.

         The parties hereto acknowledge and agree that, notwithstanding Section
11.07, the transfer of the Trust Mortgage Loans and the related rights and
property accomplished hereby is absolute and is intended by them to constitute a
sale.

         (b) In connection with the Depositor's assignment pursuant to Section
2.01(a) above, the Depositor shall, in the case of each UBS Trust Mortgage Loan,
direct the UBS Mortgage Loan Seller (pursuant to the UBS/Depositor Mortgage Loan
Purchase Agreement) to deliver to and deposit with the Trustee or a Custodian
appointed thereby, and shall, in the case of each Lehman Trust Mortgage Loan,
itself deliver to and deposit with the Trustee or a Custodian appointed thereby,
on or before the Closing Date, the Mortgage File for such Trust Mortgage Loan,
with copies of the related Mortgage Note, Mortgage(s) and reserve and cash
management agreements for such Trust Mortgage Loan to be delivered to the Master
Servicer and the Special Servicer. None of the Trustee, any Custodian, the
Master Servicer or the Special Servicer shall be liable for any failure by a
Mortgage Loan Seller or the Depositor to comply with the document delivery
requirements of the respective Mortgage Loan Purchase Agreements and this
Section 2.01(b).

         After the Depositor's transfer of the Trust Mortgage Loans to the
Trustee pursuant to Section 2.01(a), the Depositor shall not take any action
inconsistent with the Trust's ownership of the Trust Mortgage Loans.

                                      -93-

         (c) The Depositor hereby represents and warrants that it has retained
or caused to be retained, with respect to each Lehman Trust Mortgage Loan, and
the UBS Mortgage Loan Seller has covenanted in the UBS/Depositor Mortgage Loan
Purchase Agreement that it shall retain with respect to each UBS Trust Mortgage
Loan, an Independent Person (each such Person, a "Recording/Filing Agent") for
purposes of promptly (and in any event within 45 days following the later of the
Closing Date and the date on which all necessary recording or filing (as
applicable) information is available to such Recording/Filing Agent) recording
or filing, as the case may be, in the appropriate public office for real
property records or UCC Financing Statements, as appropriate, each related
assignment of Mortgage and assignment of Assignment of Leases in favor of the
Trustee referred to in clause (iv) of the definition of "Mortgage File" and each
related assignment of UCC Financing Statement in favor of the Trustee referred
to in clause (viii) of the definition of "Mortgage File".

         Notwithstanding the foregoing, the Depositor may, in the case of a
Lehman Trust Mortgage Loan, and the UBS Mortgage Loan Seller may, in the case of
a UBS Trust Mortgage Loan, request the Trustee to record or file, as applicable,
any of the assignments of Mortgage, assignments of Assignment of Leases or
assignments of UCC Financing Statements referred to above, and in such event,
the requesting party shall cause any such unrecorded or unfiled document to be
delivered to the Trustee. The Trustee shall promptly undertake to record or file
any such document upon its receipt thereof.

         The Depositor shall bear the costs of the recording and filing referred
to in the prior two paragraphs with respect to the Lehman Trust Mortgage Loans,
and the Depositor represents and warrants that the UBS/Depositor Mortgage Loan
Purchase Agreement provides that the UBS Mortgage Loan Seller shall bear the
costs of the recording and filing referred to in the prior two paragraphs with
respect to the UBS Trust Mortgage Loans. The Depositor hereby covenants as to
each Lehman Trust Mortgage Loan, and the UBS Mortgage Loan Seller has covenanted
in the UBS/Depositor Mortgage Loan Purchase Agreement as to each UBS Trust
Mortgage Loan, that it will cause the applicable Recording/Filing Agent to
forward to the Trustee each related assignment of Mortgage, assignment of
Assignment of Leases and each assignment of UCC Financing Statement in favor of
the Trustee following its return by the applicable public recording or filing
office, as the case may be; provided that, in those instances where the public
recording office retains the original assignment of Mortgage or assignment of
Assignment of Leases, a certified copy of the recorded original shall be
forwarded to the Trustee. Each assignment referred to in the prior two
paragraphs that is recorded by the Trustee shall reflect that it should be
returned by the public recording office to the Trustee or its agent or to the
applicable Recording/Filing Agent, following recording, and each assignment of
UCC Financing Statement referred to in the prior two paragraphs that is filed by
the Trustee shall reflect that the file copy thereof should be returned to the
Trustee or its agent following filing; provided that, in those instances where
the public recording office retains the original assignment of Mortgage or
assignment of Assignment of Leases, the Trustee shall obtain therefrom a
certified copy of the recorded original. At least every 90 days after the
Closing Date (or at additional times upon the request of the Master Servicer if
reasonably necessary for the ongoing administration and/or servicing of the
related Trust Mortgage Loan by the Master Servicer) and at the expense of the
Depositor (in the case of a Lehman Trust Mortgage Loan) or the UBS Mortgage Loan
Seller (in the case of a UBS Trust Mortgage Loan), the Trustee shall forward to
the Master Servicer a copy of any of the aforementioned assignments that have
been received by the Trustee.

                                      -94-
<PAGE>

         If any of the aforementioned assignments relating to a UBS Trust
Mortgage Loan is lost or returned unrecorded or unfiled, as the case may be,
because of a defect therein, then the Trustee shall direct the UBS Mortgage Loan
Seller (pursuant to the UBS/Depositor Mortgage Loan Purchase Agreement) promptly
to prepare or cause the preparation of a substitute therefor or to cure such
defect, as the case may be, and to deliver to the Trustee the substitute or
corrected document. If any of the aforementioned assignments relating to a
Lehman Trust Mortgage Loan is lost or returned unrecorded or unfiled, as the
case may be, because of a defect therein, then the Depositor shall promptly
prepare or cause the preparation of a substitute therefor or cure such defect,
as the case may be, and shall deliver to the Trustee the substitute or corrected
document. The Trustee shall upon receipt, whether from the UBS Mortgage Loan
Seller or the Depositor, cause the same to be duly recorded or filed, as
appropriate.

         (d) In connection with the Depositor's assignment pursuant to Section
2.01(a) above, the Depositor shall, in the case of each UBS Trust Mortgage Loan,
direct the UBS Mortgage Loan Seller (pursuant to the UBS/Depositor Mortgage Loan
Purchase Agreement) to deliver to and deposit with the Master Servicer, and
shall, in the case of each Lehman Trust Mortgage Loan, itself deliver to and
deposit with the Master Servicer, on or before the Closing Date, such other
relevant documents and records that: (A) relate to the administration or
servicing of such Trust Mortgage Loan, (B) are reasonably necessary for the
ongoing administration and/or servicing of such Trust Mortgage Loan by the
Master Servicer in connection with its duties under this Agreement, and (C) are
in the possession or under the control of the UBS Mortgage Loan Seller or the
Depositor, as applicable, together with (i) all unapplied Escrow Payments and
Reserve Funds in the possession of the UBS Mortgage Loan Seller or the
Depositor, as the case may be, that relate to such Trust Mortgage Loan and (ii)
a statement indicating which Escrow Payments and Reserve Funds are allocable to
such Trust Mortgage Loan; provided that neither the Depositor nor the UBS
Mortgage Loan Seller shall be required to deliver any draft documents,
privileged or other communications, credit underwriting or due diligence
analyses, credit committee briefs or memoranda or other internal approval
documents or data or internal worksheets, memoranda, communications or
evaluations. In addition, pursuant to the UBS/Depositor Mortgage Loan Purchase
Agreement, the UBS Mortgage Loan Seller will be required to deliver, on the
Closing Date, the Initial Deposit to the Master Servicer for deposit in the Pool
Custodial Account. The Master Servicer shall hold all such documents, records
and funds on behalf of the Trustee in trust for the benefit of the
Certificateholders (and, insofar as they also relate to any Non-Trust Mortgage
Loan, on behalf of and for the benefit of the related Non-Trust Mortgage Loan
Noteholder).

         (e) In connection with the obligations of the Master Servicer under
Sections 3.01(e) and 3.19(c), with regard to each Trust Mortgage Loan that is
secured by the interests of the related Mortgagor in a hospitality property and
each Trust Mortgage Loan that has a related letter of credit, the Depositor
(with respect to each such Lehman Trust Mortgage Loan) shall, and the UBS
Mortgage Loan Seller (with respect to each such UBS Trust Mortgage Loan) will be
obligated under the UBS/Depositor Mortgage Loan Purchase Agreement to, deliver
to and deposit with the Master Servicer, on or before the Closing Date, any
related franchise agreement and franchise comfort letter and the original of
such letter of credit.

         (f) It is not intended that this Agreement create a partnership or a
joint-stock association.

         SECTION 2.02. Acceptance of Trust Fund by Trustee.

         (a) The Trustee, by its execution and delivery of this Agreement,
hereby accepts receipt, directly or through a Custodian on its behalf, of (i)
the Trust Mortgage Loans and all documents delivered to it that constitute
portions of the related Mortgage Files and (ii) all other assets delivered to it
and included in the Trust Fund, in good faith and without notice of any adverse
claim, and declares that it or a Custodian on its behalf holds and will hold
such documents and any other documents subsequently received by it that
constitute portions of the Mortgage Files, and that it holds and will hold the
Trust Mortgage Loans and such other assets, together with any other assets
subsequently delivered to it that are to be included in the Trust Fund, in trust
for the exclusive use and benefit of all present and future Certificateholders.
To the extent that the Mortgage File for any Trust Mortgage Loan that is part of
a Loan Combination relates to a Non-Trust Mortgage Loan, the Trustee shall also
hold such Mortgage File in trust for the use and benefit of the related
Non-Trust Mortgage Loan Noteholder. In connection with the foregoing, the
Trustee hereby certifies to each of the other parties hereto, each Mortgage Loan
Seller and each Underwriter that, as to each Trust Mortgage Loan, (i) the
Specially Designated Mortgage Loan Documents are in its possession or the
possession of a Custodian on its behalf, and (ii) the original Mortgage Note
(or, if accompanied by a lost note affidavit, the copy of such Mortgage Note)
received by it or any Custodian with respect to such Trust Mortgage Loan has
been reviewed by it or by such Custodian on its behalf and (A) appears regular
on its face (handwritten additions, changes or corrections shall not constitute
irregularities if initialed by the Mortgagor), (B) appears to have been executed
(where appropriate) and (C) purports to relate to such Trust Mortgage Loan.

         (b) On or about the 45th day following the Closing Date (and, if any
exceptions are noted, again on or about the 90th day following the Closing Date
and monthly thereafter until the earliest of (i) the second anniversary of the
Closing Date, (ii) the day on which all material exceptions have been removed
and (iii) the day on which the Depositor has repurchased the last affected Trust
Mortgage Loan), the Trustee or a Custodian on its behalf shall review the
documents delivered to it or such Custodian with respect to each Mortgage Loan,
and the Trustee shall, subject to Sections 2.01, 2.02(c) and 2.02(d), certify in
writing (substantially in the form of Exhibit C hereto) to each of the other
parties hereto, each Mortgage Loan Seller and each Underwriter (and, in the case
of a Non-Trust Mortgage Loan, the related Non-Trust Mortgage Loan Noteholder)
that, as to each Mortgage Loan then subject to this Agreement (except as
specifically identified in any exception report annexed to such certification):
(i) all documents specified in clauses (i) through (v), (vii), (viii) and (ix)
of the definition of "Mortgage File" (without regard to the second parenthetical
in such clause (viii)), are in its possession or the possession of a Custodian
on its behalf; (ii) the recordation/filing contemplated by Section 2.01(c) has
been completed (based solely on receipt by the Trustee of the particular
recorded/filed documents); (iii) all documents received by it or any Custodian
with respect to such Mortgage Loan have been reviewed by it or by such Custodian
on its behalf and (A) appear regular on their face (handwritten additions,
changes or corrections shall not constitute irregularities if initialed by the
Mortgagor), (B) appear to have been executed (where appropriate) and (C) purport
to relate to such Mortgage Loan; and (iv) based on the examinations referred to
in Section 2.02(a) above and this Section 2.02(b) and only as to the foregoing
documents, the information set forth in the Trust Mortgage Loan Schedule with
respect to the items specified in clauses (v) and (vi)(B) of the definition of
"Trust Mortgage Loan Schedule" accurately reflects the information set forth in
the Mortgage File. If the Trustee's obligation to deliver the certifications
contemplated in this subsection terminates because two years have elapsed since
the Closing Date, the Trustee shall deliver a comparable certification, upon
request, to any party hereto, any Non-Trust Mortgage Loan Noteholder and/or any
Underwriter.

                                      -96-
<PAGE>

         (c) None of the Trustee, the Master Servicer, the Special Servicer or
any Custodian is under any duty or obligation to inspect, review or examine any
of the documents, instruments, certificates or other papers relating to the
Mortgage Loans delivered to it to determine that the same are valid, legal,
effective, genuine, binding, enforceable, sufficient or appropriate for the
represented purpose or that they are other than what they purport to be on their
face. Furthermore, none of the Trustee, the Master Servicer, the Special
Servicer or any Custodian shall have any responsibility for determining whether
the text of any assignment or endorsement is in proper or recordable form,
whether the requisite recording of any document is in accordance with the
requirements of any applicable jurisdiction, or whether a blanket assignment is
permitted in any applicable jurisdiction.

         (d) It is understood that the scope of the Trustee's review of the
Mortgage Files is limited solely to confirming that the documents specified in
clauses (i) through (v), (vii), (viii) and (ix) of the definition of "Mortgage
File" have been received and such additional information as will be necessary
for delivering the certifications required by Sections 2.02(a) and (b) above.

         (e) If, after the Closing Date, the Depositor comes into possession of
any documents or records that constitute part of the Mortgage File or Servicing
File for any Mortgage Loan, the Depositor shall promptly return such document to
the Trustee (if it constitutes part of the Mortgage File) or the Master Servicer
(if it constitutes part of the Servicing File), as applicable.

         SECTION 2.03. Repurchase of Trust Mortgage Loans for Document Defects
                       and Breaches of Representations and Warranties.

         (a) If any party hereto discovers that any document constituting a part
of a Mortgage File has not been properly executed, is missing, contains
information that does not conform in any material respect with the corresponding
information set forth in the Trust Mortgage Loan Schedule, or does not appear to
be regular on its face (each, a "Document Defect"), or discovers or receives
notice of a breach of any representation or warranty of the UBS Mortgage Loan
Seller made pursuant to Section 3(b) of the UBS/Depositor Mortgage Loan Purchase
Agreement with respect to any UBS Trust Mortgage Loan (a "Breach"), or discovers
or receives notice of a breach of any representation or warranty of the
Depositor set forth in Section 2.04(b) with respect to any Lehman Trust Mortgage
Loan (also, a "Breach"), such party shall give prompt written notice thereof to
each Rating Agency, the related Mortgage Loan Seller, the other parties hereto
and the Controlling Class Representative. If any such Document Defect or Breach
with respect to any Trust Mortgage Loan materially and adversely affects the
interests of the Certificateholders therein, then such Document Defect shall
constitute a "Material Document Defect" or such Breach shall constitute a
"Material Breach", as the case may be. Notwithstanding anything herein to the
contrary, the failure by the Depositor (in the case of a Lehman Trust Mortgage
Loan) and/or the UBS Mortgage Loan Seller (in the case of a UBS Trust Mortgage
Loan) to deliver, to the extent required, any item set forth under clause
(a)(viii) of the definition of "Mortgage File", with respect to a Trust Mortgage
Loan secured by any property other than a hospitality property, can never
constitute a Material Document Defect for any purpose under this Agreement or
under the UBS/Depositor Mortgage Loan Purchase Agreement.

         Promptly upon becoming aware of any such Material Document Defect or
Material Breach with respect to a UBS Trust Mortgage Loan, the Trustee shall
deliver a Seller/Depositor Notification to the UBS Mortgage Loan Seller, the
Master Servicer and the Special Servicer and shall require the UBS Mortgage Loan
Seller, within the time period and subject to the conditions provided for

                                      -97-
<PAGE>

in the UBS/Depositor Mortgage Loan Purchase Agreement, to cure such Material
Document Defect or Material Breach, as the case may be, or repurchase the
affected Trust Mortgage Loan or any related REO Property (or, in the case of an
REO Property related to a Loan Combination, the Trust's interest therein) at the
applicable Purchase Price by wire transfer of immediately available funds to the
Pool Custodial Account. Promptly upon becoming aware of any such Material
Document Defect or Material Breach with respect to a Lehman Trust Mortgage Loan,
the Trustee shall deliver a Seller/Depositor Notification to the Depositor, the
Master Servicer and the Special Servicer, and the Depositor shall, not later
than 90 days from the Depositor's receipt of such Seller/Depositor Notification
regarding such Material Document Defect or Material Breach, as the case may be
(or, in the case of a Material Document Defect or Material Breach relating to a
Lehman Trust Mortgage Loan not being a "qualified mortgage" within the meaning
of the REMIC Provisions, not later than 90 days following any party discovering
such Material Document Defect or Material Breach) (any such 90-day period (with
respect to a Lehman Trust Mortgage Loan), and any "Initial Resolution Period",
as defined in the UBS/Depositor Mortgage Loan Purchase Agreement (with respect
to a UBS Trust Mortgage Loan), as applicable, are each referred to herein as the
"Initial Resolution Period"), cure the same in all material respects (which cure
shall include payment of losses and any Additional Trust Fund Expenses
associated therewith) or, if such Material Document Defect or Material Breach,
as the case may be, cannot be cured within the Initial Resolution Period,
repurchase the affected Lehman Trust Mortgage Loan or any related REO Property
(or, in the case of an REO Property related to a Loan Combination, the Trust's
interest therein) at the applicable Purchase Price by wire transfer of
immediately available funds to the Pool Custodial Account; provided, however,
that if (i) such Material Document Defect or Material Breach is capable of being
cured but not within the Initial Resolution Period, (ii) such Material Document
Defect or Material Breach is not related to any Lehman Trust Mortgage Loan's not
being a "qualified mortgage" within the meaning of the REMIC Provisions and
(iii) the Depositor has commenced and is diligently proceeding with the cure of
such Material Document Defect or Material Breach within the Initial Resolution
Period, then the Depositor shall have an additional period equal to the
applicable Resolution Extension Period to complete such cure or, in the event of
a failure to so cure, to complete such repurchase (it being understood and
agreed that, in connection with the Depositor's receiving such extension of time
equal to the applicable Resolution Extension Period, the Depositor shall deliver
an Officer's Certificate to the Trustee setting forth the reasons such Material
Document Defect or Material Breach is not capable of being cured within the
Initial Resolution Period and what actions the Depositor is pursuing in
connection with the cure thereof and stating that the Depositor anticipates that
such Material Document Defect or Material Breach will be cured within the
applicable Resolution Extension Period); and provided, further, that, if any
such Material Document Defect is still not cured after the Initial Resolution
Period and any such Resolution Extension Period solely due to the failure of the
Depositor to have received a recorded document, then the Depositor shall be
entitled to continue to defer its cure and repurchase obligations in respect of
such Document Defect so long as the Depositor certifies to the Trustee every six
months thereafter that the Document Defect is still in effect solely because of
its failure to have received the recorded document and that the Depositor is
diligently pursuing the cure of such defect (specifying the actions being
taken).

         If, during the period of deferral by the Depositor of its cure and
repurchase obligations as contemplated by the last proviso of the preceding
paragraph, or during any comparable deferral by the UBS Mortgage Loan Seller of
its cure and repurchase obligations as provided in Section 5(a) of the
UBS/Depositor Mortgage Loan Purchase Agreement, as applicable, the Trust
Mortgage Loan that is the subject of the Material Document Defect either becomes
a Specially Serviced Trust Mortgage Loan or becomes the subject of a proposed or
actual assumption of the obligations of the related Mortgagor

                                      -98-
<PAGE>

under such Trust Mortgage Loan, then (i) any party to this Agreement that
becomes aware of such event shall deliver a Seller/Depositor Notification to
such effect (unless a Seller/Depositor Notification with respect to such event
has already been delivered by another party) to the Master Servicer, the Special
Servicer, the Trustee, the Depositor (in the case of a Lehman Trust Mortgage
Loan) and the UBS Mortgage Loan Seller (in the case of a UBS Trust Mortgage
Loan), and (ii) the Trustee, upon becoming aware of such event, shall deliver a
Seller/Depositor Notification to the Master Servicer, the Special Servicer, the
Depositor (in the case of a Lehman Trust Mortgage Loan) and the UBS Mortgage
Loan Seller (in the case of a UBS Trust Mortgage Loan), providing notice of such
event and directing the Depositor or the UBS Mortgage Loan Seller, as
applicable, to cure the subject Material Document Defect within 15 days of
receipt of such Seller/Depositor Notification. If, upon the expiration of such
15-day period, the Depositor or the UBS Mortgage Loan Seller, as applicable, has
failed to cure the subject Material Document Defect, the Master Servicer or the
Special Servicer, as applicable, shall be entitled (but not obligated) to
perform the obligations of the Depositor or the UBS Mortgage Loan Seller, as
applicable, with respect to curing the subject Material Document Defect; and,
upon electing to perform such obligations, the Master Servicer or the Special
Servicer, as applicable, shall promptly deliver a Seller/Depositor Notification
to such effect. In connection with the preceding sentence, the Depositor will,
and the UBS Mortgage Loan Seller will be obligated under the UBS/Depositor
Mortgage Loan Purchase Agreement to, pay all reasonable costs and expenses in
connection with the applicable servicer's effecting such cure.

         (b) In connection with the events in Section 2.03(a), the Trustee shall
prepare and deliver, in each case promptly upon becoming aware of such event, to
the Master Servicer, the Special Servicer and either the Depositor (with respect
to a Lehman Trust Mortgage Loan) or the UBS Mortgage Loan Seller (with respect
to a UBS Trust Mortgage Loan), as applicable, a Seller/Depositor Notification
identifying and describing the circumstances identified in the definition of
"Seller/Depositor Notification" (unless, in the case of an event described in
clauses (iii), (iv) and/or (vi), as applicable, of the definition of
"Seller/Depositor Notification", a Seller/Depositor Notification with respect to
such event has already been delivered by the Master Servicer or the Special
Servicer). Further, in connection with the events in Section 2.03(a), the Master
Servicer or the Special Servicer, as applicable, shall prepare and deliver, in
each case promptly upon becoming aware of such event, to the other such
servicer, the Trustee and either the Depositor (with respect to a Lehman Trust
Mortgage Loan) or the UBS Mortgage Loan Seller (with respect to a UBS Trust
Mortgage Loan), as applicable, a Seller/Depositor Notification identifying and
describing the circumstances identified in clauses (iii), (iv) and/or (vi), as
applicable, of the definition of "Seller/Depositor Notification" (unless such
notification has already been delivered). A copy of each such Seller/Depositor
Notification shall also be delivered to the Controlling Class Representative
and, in the case of an event described in clauses (v) and/or (vii) of the
definition of "Seller/Depositor Notification", to either internal counsel to the
Depositor (with respect to a Lehman Trust Mortgage Loan) or counsel to the UBS
Mortgage Loan Seller (with respect to a UBS Trust Mortgage Loan), as applicable,
to the extent the Trustee, Master Servicer or Special Servicer, as applicable,
knows the identity of such person.

         (c) If one or more (but not all) of the Trust Mortgage Loans
constituting a Cross-Collateralized Group are to be repurchased by the Depositor
or the UBS Mortgage Loan Seller as contemplated by this Section 2.03, then,
prior to the subject repurchase, the Depositor or the UBS Mortgage Loan Seller,
as the case may be, or its designee shall use its reasonable efforts, subject to
the terms of the related Trust Mortgage Loan(s), to prepare and, to the extent
necessary and appropriate, have executed by the related Mortgagor and record,
such documentation as may be necessary to

                                      -99-
<PAGE>

terminate the cross-collateralization between the Trust Mortgage Loan(s) in such
Cross-Collateralized Group that are to be repurchased, on the one hand, and the
remaining Trust Mortgage Loan(s) therein, on the other hand, such that those two
groups of Trust Mortgage Loans are each secured only by the Mortgaged Properties
identified in the Trust Mortgage Loan Schedule as directly corresponding
thereto; provided that no such termination shall be effected unless and until
(i) the Controlling Class Representative, if one is then acting, has consented
(which consent shall not be unreasonably withheld and shall be deemed to have
been given if no written objection is received by the Depositor or the UBS
Mortgage Loan Seller, as the case may be, within ten (10) Business Days of the
Controlling Class Representative's receipt of a written request for such
consent) and (ii) the Trustee has received from the Depositor or the UBS
Mortgage Loan Seller, as the case may be, (A) an Opinion of Counsel to the
effect that such termination would not cause an Adverse REMIC Event to occur
with respect to any REMIC Pool or an Adverse Grantor Trust Event to occur with
respect to the Grantor Trust and (B) written confirmation from each Rating
Agency that such termination would not cause an Adverse Rating Event to occur
with respect to any Class of Certificates; and provided, further, that the
Depositor, in the case of Lehman Trust Mortgage Loans, or the UBS Mortgage Loan
Seller, in the case of UBS Trust Mortgage Loans, may, at its option, purchase
the entire subject Cross-Collateralized Group in lieu of effecting a termination
of the cross-collateralization. All costs and expenses incurred by the Trustee
or any Person on its behalf pursuant to this paragraph shall be included in the
calculation of the Purchase Price for the Trust Mortgage Loan(s) to be
repurchased. If the cross-collateralization of any Cross-Collateralized Group is
not or cannot be terminated as contemplated by this paragraph, then, for
purposes of (i) determining the materiality of any Breach or Defect, as the case
may be, and (ii) the application of remedies, such Cross-Collateralized Group
shall be treated as a single Trust Mortgage Loan.

         (d) In the event the Depositor is obligated to repurchase any Lehman
Trust Mortgage Loan pursuant to this Section 2.03, and/or the UBS Mortgage Loan
Seller is obligated to repurchase any UBS Trust Mortgage Loan pursuant to the
UBS/Depositor Mortgage Loan Purchase Agreement, such obligation shall extend to
any REO Trust Mortgage Loan as to which (i) the subject Material Breach existed
as to the subject predecessor Trust Mortgage Loan prior to the date the related
Mortgaged Property became an REO Property or within 90 days thereafter, and (ii)
the party having the repurchase obligation had received, no later than 90 days
following the date on which the related Mortgaged Property became an REO
Property, a Seller/Depositor Notification from the Trustee regarding the
occurrence of the applicable Material Breach and directing such party to
repurchase the subject Trust Mortgage Loan.

         (e) Notwithstanding the foregoing, if there exists a Breach of that
portion of the representation or warranty on the part of the Depositor set forth
in, or made pursuant to, Section 2.04(b)(xxvi) or Section 2.04(b)(xlviii), or on
the part of the UBS Mortgage Loan Seller set forth in, or made pursuant to,
paragraph (xxvi) or paragraph (xlviii) of Exhibit B to the UBS/Depositor
Mortgage Loan Purchase Agreement, in each case specifically relating to whether
or not the Mortgage Loan documents or any particular Mortgage Loan document for
any Mortgage Loan requires the related Mortgagor to bear the reasonable costs
and expenses associated with the subject matter of such representation or
warranty, as set forth in such representation or warranty, then the Master
Servicer shall (and the Special Servicer may) direct the Depositor (in the case
of a Lehman Trust Mortgage Loan) or the UBS Mortgage Loan Seller (in the case of
a UBS Trust Mortgage Loan) in writing to wire transfer to the Pool Custodial
Account, within 90 days of such party's receipt of such direction, the amount of
any such reasonable costs and expenses incurred by the Trust that (i) are due
from the Mortgagor, (ii) otherwise would have been required to be paid by the
Mortgagor if such representation or warranty

                                     -100-
<PAGE>

with respect to such costs and expenses had in fact been true, as set forth in
the related representation or warranty, (iii) have not been paid by the
Mortgagor, (iv) are the basis of such Breach and (v) constitute "Covered Costs".
Upon payment of such costs, the Depositor (in the case of a Lehman Trust
Mortgage Loan) or the UBS Mortgage Loan Seller (in the case of a UBS Trust
Mortgage Loan) shall be deemed to have cured such Breach in all respects.
Provided that such payment is made, this paragraph describes the sole remedy
available to the Certificateholders and the Trustee on their behalf regarding
any such Breach, regardless of whether it constitutes a Material Breach, and
neither the Depositor (in the case of a Lehman Trust Mortgage Loan) nor the UBS
Mortgage Loan Seller (in the case of a UBS Trust Mortgage Loan) shall be
obligated to otherwise cure such Breach or repurchase the affected Trust
Mortgage Loan under any circumstances. Amounts deposited in the Pool Custodial
Account pursuant to this paragraph shall constitute "Liquidation Proceeds" for
all purposes of this Agreement (other than Section 3.11(c)).

         (f) In connection with any repurchase of a Trust Mortgage Loan pursuant
to or otherwise as contemplated by this Section 2.03, the Trustee, the
Custodian, the Master Servicer and the Special Servicer shall each tender to the
repurchasing entity, upon delivery to each of them of a receipt executed by the
repurchasing entity, all portions of the Mortgage File and other documents
pertaining to such Trust Mortgage Loan possessed by it, and each document that
constitutes a part of the Mortgage File shall be endorsed or assigned to the
extent necessary or appropriate to the repurchasing entity or its designee in
the same manner, but only if the respective documents have been previously
assigned or endorsed to the Trustee, and pursuant to appropriate forms of
assignment, substantially similar to the manner and forms pursuant to which such
documents were previously assigned to the Trustee; provided that such tender by
the Trustee shall be conditioned upon its receipt from the Master Servicer of a
Request for Release accompanied by a certification of a Servicing Officer to the
effect that all amounts received or to be received in connection with such
repurchase which are required to be deposited in the applicable Custodial
Account pursuant to Section 3.04(a), 3.04A(a) or 3.04B(a), as applicable, have
been deposited. The Master Servicer shall, and is hereby authorized and
empowered by the Trustee to, prepare, execute and deliver in its own name, on
behalf of the Certificateholders and the Trustee or any of them, the
endorsements and assignments contemplated by this Section 2.03(f), and such
other instruments as may be necessary or appropriate to transfer title to an REO
Property or any interest therein in connection with the repurchase of an REO
Trust Mortgage Loan and the Trustee shall execute and deliver any powers of
attorney necessary to permit the Master Servicer to do so; provided, however,
that the Trustee shall not be held liable for any misuse of any such power of
attorney by the Master Servicer.

         (g) The UBS/Depositor Mortgage Loan Purchase Agreement provides the
sole remedies available to the Certificateholders, or the Trustee on behalf of
the Certificateholders, respecting any Document Defect or Breach with respect to
any UBS Trust Mortgage Loan. This Section 2.03 provides the sole remedies
available to the Certificateholders, or the Trustee on behalf of the
Certificateholders, respecting any Document Defect or Breach with respect to any
Lehman Trust Mortgage Loan.

         SECTION 2.04. Representations, Warranties and Covenants of the
                       Depositor.

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

                  (i) The Depositor is a corporation duly organized, validly
         existing and in good standing under the laws of the State of Delaware.

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

                  (iii) The Depositor has the full power and authority to enter
         into and consummate all transactions contemplated by this Agreement,
         has duly 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 each of the other parties hereto, constitutes a valid,
         legal and binding obligation of the Depositor, enforceable against the
         Depositor in accordance with the terms hereof, subject to (A)
         applicable bankruptcy, insolvency, reorganization, moratorium and other
         laws affecting the enforcement of creditors' rights generally, and (B)
         general principles of equity, regardless of whether such enforcement is
         considered in a proceeding in equity or at law.

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

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

                  (vii) The Depositor is not transferring the Trust Mortgage
         Loans to the Trustee with any intent to hinder, delay or defraud its
         present or future creditors.

                  (viii) The Depositor has been solvent at all relevant times
         prior to, and will not be rendered insolvent by, its transfer of the
         Trust Mortgage Loans to the Trustee pursuant to Section 2.01(a).

                                     -102-

                  (ix) After giving effect to its transfer of the Trust Mortgage
         Loans to the Trustee pursuant to Section 2.01(a), the value of the
         Depositor's assets, either taken at their present fair saleable value
         or at fair valuation, will exceed the amount of the Depositor's debts
         and obligations, including contingent and unliquidated debts and
         obligations of the Depositor, and the Depositor will not be left with
         unreasonably small assets or capital with which to engage in and
         conduct its business.

                  (x) The Depositor does not intend to, and does not believe
         that it will, incur debts or obligations beyond its ability to pay such
         debts and obligations as they mature.

                  (xi) No proceedings looking toward merger, liquidation,
         dissolution or bankruptcy of the Depositor are pending or contemplated.

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

                  (xiii) Except for any actions that are the express
         responsibility of another party hereunder or under the Mortgage Loan
         Purchase Agreements, and further except for actions that the Depositor
         is expressly permitted to complete subsequent to the Closing Date, the
         Depositor has taken all actions required under applicable law to
         effectuate the transfer of the Trust Mortgage Loans by the Depositor to
         the Trustee.

                  (xiv) Immediately prior to the transfer of the UBS Trust
         Mortgage Loans to the Trust pursuant to this Agreement (and assuming
         that the UBS Mortgage Loan Seller transferred to the Depositor good and
         marketable title to each UBS Trust Mortgage Loan, free and clear of all
         liens, claims, encumbrances and other interests), (A) the Depositor had
         good and marketable title to, and was the sole owner and holder of,
         each UBS Trust Mortgage Loan; and (B) the Depositor has full right and
         authority to sell, assign and transfer the UBS Trust Mortgage Loans,
         exclusive of the servicing rights pertaining thereto.

         (b) The Depositor hereby represents and warrants to the Trustee, for
its own benefit and the benefit of the Certificateholders, with respect to each
Lehman Trust Mortgage Loan only, as of the Closing Date or such other date
specified in the particular representation and warranty, subject to the
exceptions set forth on Schedule II hereto, as follows (the headings set forth
in this Section 2.04(b) with respect to each representation and warranty being
for convenience of reference only and in no way limiting, expanding or otherwise
affecting the scope or subject matter thereof):

                  (i) Trust Mortgage Loan Schedule. The information pertaining
         to such Mortgage Loan set forth in the Trust Mortgage Loan Schedule was
         true and correct in all material respects as of its Due Date in January
         2004.

                  (ii) Legal Compliance. If such Mortgage Loan was originated by
         a Lehman Mortgage Loan Seller or another Affiliate of the Depositor,
         then, as of the date of its origination, such Mortgage Loan complied in
         all material respects with, or was exempt from, all

                                     -103-
<PAGE>

         requirements of federal, state or local law relating to the origination
         of such Mortgage Loan; and, if such Mortgage Loan was not originated by
         a Lehman Mortgage Loan Seller or another Affiliate of the Depositor,
         then, to the Depositor's actual knowledge, after having performed the
         type of due diligence customarily performed by prudent institutional
         commercial and multifamily mortgage lenders, as of the date of its
         origination, such Mortgage Loan complied in all material respects with,
         or was exempt from, all requirements of federal, state or local law
         relating to the origination of such Mortgage Loan.

                  (iii) Ownership of Lehman Trust Mortgage Loan. The Depositor
         owns such Mortgage Loan, has good title thereto, has full right, power
         and authority to sell, assign and transfer such Mortgage Loan and is
         transferring such Mortgage Loan free and clear of any and all liens,
         pledges, charges or security interests of any nature encumbering such
         Mortgage Loan, exclusive of the servicing rights pertaining thereto; no
         provision of the Mortgage Note, Mortgage(s) or other loan documents
         relating to such Mortgage Loan prohibits or restricts the Depositor's
         right to assign or transfer such Mortgage Loan to the Trustee (except
         in the case of a Loan Combination, which may, pursuant to the related
         Co-Lender Agreement, require notice to one or more rating agencies or
         another lender which, if required, has already been provided); no
         governmental or regulatory approval or consent is required for the sale
         of such Mortgage Loan by the Depositor; and the Depositor has validly
         conveyed to the Trustee a legal and beneficial interest in and to such
         Mortgage Loan free and clear of any lien, claim or encumbrance of any
         nature.

                  (iv) No Holdback. The proceeds of such Mortgage Loan have been
         fully disbursed (except in those cases where the full amount of such
         Mortgage Loan has been disbursed but a portion thereof is being held in
         escrow or reserve accounts to be released pending the satisfaction of
         certain conditions relating to leasing, repairs or other matters with
         respect to the related Mortgaged Property) and there is no requirement
         for future advances thereunder.

                  (v) Loan Document Status. Each of the related Mortgage Note,
         Mortgage(s), Assignment(s) of Leases, if separate from the related
         Mortgage, and other agreements executed in favor of the lender in
         connection therewith is the legal, valid and binding obligation of the
         maker thereof (subject to the non-recourse provisions therein and any
         state anti-deficiency legislation), enforceable in accordance with its
         terms, except that (A) such enforcement may be limited by (1)
         bankruptcy, insolvency, receivership, reorganization, liquidation,
         voidable preference, fraudulent conveyance and transfer, moratorium
         and/or other similar laws affecting the enforcement of creditors'
         rights generally, and (2) general principles of equity (regardless of
         whether such enforcement is considered in a proceeding in equity or at
         law), and (B) certain provisions in the subject agreement or instrument
         may be further limited or rendered unenforceable by applicable law, but
         subject to the limitations set forth in the foregoing clause (A), such
         limitations will not render that subject agreement or instrument
         invalid as a whole or substantially interfere with the mortgagee's
         realization of the principal benefits and/or security provided by the
         subject agreement or instrument. Such Mortgage Loan is non-recourse to
         the Mortgagor or any other Person except to the extent provided in
         certain nonrecourse carveouts and/or in any applicable guarantees. A
         natural person as individual guarantor has agreed, in effect, to be
         jointly and severally liable with the related Mortgagor, for all
         liabilities, costs, losses, damages or expenses suffered or incurred by
         the mortgagee under such Mortgage Loan by reason of or in connection
         with and to the extent of (A) any intentional fraud or material

                                     -104-
<PAGE>

         intentional misrepresentation by the related Mortgagor, (B) any breach
         on the part of the related Mortgagor of any environmental
         representations warranties, covenants or indemnity contained in the
         related Mortgage Loan documents, (C) misapplication or misappropriation
         of rents (received after an event of default), insurance proceeds or
         condemnation awards, and (D) the filing of a voluntary bankruptcy or
         insolvency proceeding by the related Mortgagor; provided that, in the
         case of any breach described in clause (B) of this paragraph, such
         entity (or individual) may instead cover through environmental
         insurance liabilities, costs, losses, damages, expenses and claims
         resulting from a breach of the obligations and indemnities of the
         related Mortgagor under the related Mortgage Loan documents relating to
         hazardous or toxic substances, radon or compliance with environmental
         laws.

                  (vi) No Right of Rescission. Subject to the limitations and
         exceptions as to enforceability set forth in paragraph (b)(v) above,
         there is no valid offset, defense, counterclaim or right to rescission,
         abatement or diminution with respect to any of the related Mortgage
         Note, Mortgage(s) or other agreements executed in connection with such
         Mortgage Loan; and, as of the Closing Date, to the actual knowledge of
         the Depositor, no such claim has been asserted.

                  (vii) Assignments. The assignment of the related Mortgage(s)
         and Assignment(s) of Leases to the Trustee constitutes the legal,
         valid, binding and, subject to the limitations and exceptions as to
         enforceability set forth in paragraph (b)(v) above, enforceable
         assignment of such documents (provided that the unenforceability of any
         such assignment based on bankruptcy, insolvency, receivership,
         reorganization, liquidation, moratorium and/or other similar laws
         affecting the enforcement of creditors' rights generally or based on
         general principles of equity (regardless of whether such enforcement is
         considered in a proceeding in equity or at law) shall be a breach of
         this representation and warranty only upon the declaration by a court
         with jurisdiction in the matter that such assignment is to be
         unenforceable on such basis).

                  (viii) First Lien. Each related Mortgage is a valid and,
         subject to the limitations and exceptions in paragraph (b)(v) above,
         enforceable first lien on the related Mortgaged Property including all
         improvements thereon and appurtenances and rights related thereto,
         which Mortgaged Property is free and clear of all encumbrances and
         liens having priority over or on a parity with the first lien of such
         Mortgage, except for the following (collectively, the "Permitted
         Encumbrances"): (A) the lien for real estate taxes, water charges,
         sewer rents and assessments not yet due and payable; (B) covenants,
         conditions and restrictions, rights of way, easements and other matters
         that are of public record or that are omitted as exceptions in the
         related lender's title insurance policy (or, if not yet issued, omitted
         as exceptions in a fully binding pro forma title policy or title policy
         commitment); (C) the rights of tenants (as tenants only) under leases
         (including subleases) pertaining to the related Mortgaged Property; (D)
         condominium declarations of record and identified in the related
         lender's title insurance policy (or, if not yet issued, identified in a
         pro forma title policy or title policy commitment); and (E) if such
         Mortgage Loan constitutes a Cross-Collateralized Mortgage Loan, the
         lien of the Mortgage for another Mortgage Loan contained in the same
         Cross-Collateralized Group; provided that, in the case of a Lehman
         Trust Mortgage Loan that is part of a Loan Combination, such Mortgage
         also secures the related Non-Trust Mortgage Loan(s). With respect to
         such Mortgage Loan, such Permitted Encumbrances do not, individually or
         in the aggregate, materially and adversely interfere with the benefits
         of the security intended to be provided by the

                                     -105-
<PAGE>

         related Mortgage, the current principal use or operation of the related
         Mortgaged Property or the ability of the related Mortgaged Property to
         generate sufficient cashflow to enable the related Mortgagor to timely
         pay in full the principal and interest on the related Mortgage Note
         (other than a Balloon Payment, which would require a refinancing). If
         the related Mortgaged Property is operated as a nursing facility or a
         hospitality property, the related Mortgage, together with any security
         agreement, chattel mortgage or similar agreement and UCC financing
         statement, if any, establishes and creates a first priority, perfected
         security interest (subject only to any prior purchase money security
         interest, revolving credit lines and any personal property leases), to
         the extent such security interest can be perfected by the recordation
         of a Mortgage or the filing of a UCC financing statement, in all
         material personal property owned by the Mortgagor that is used in, and
         is reasonably necessary to, the operation of the related Mortgaged
         Property as presently operated by the Mortgagor, and that is located on
         the related Mortgaged Property, which personal property includes, in
         the case of Mortgaged Properties operated by the related Mortgagor as a
         nursing facility or hospitality property, all furniture, fixtures,
         equipment and other personal property located at the subject Mortgaged
         Property that are owned by the related Mortgagor and reasonably
         necessary or material to the operation of the subject Mortgaged
         Property. In the case of any Lehman Trust Mortgage Loan secured by a
         hotel, the related loan documents contain such provisions as are
         necessary and UCC financing statements have been filed as necessary, in
         each case, to perfect a valid first priority security interest, to the
         extent such security interest can be perfected by the inclusion of such
         provisions and the filing of a UCC financing statement, in the
         Mortgagor's right to receive related hotel room revenues with respect
         to such Mortgaged Property.

                  (ix) Taxes and Assessments. All taxes, governmental
         assessments, water charges, sewer rents or similar governmental charges
         (which, in all such cases, were directly related to the related
         Mortgaged Property and could constitute liens on the related Mortgaged
         Property prior to the lien of the related Mortgage), together with all
         ground rents, that prior to the related Due Date in January 2004 became
         due and payable in respect of, and materially affect, any related
         Mortgaged Property have been paid or are not yet delinquent, and the
         Depositor knows of no unpaid tax, assessment, ground rent, water
         charges or sewer rent, which, in all such cases, were directly related
         to the subject Mortgaged Property and could constitute liens on the
         subject Mortgaged Property prior to the lien of the related Mortgage,
         that prior to the Closing Date became due and delinquent in respect of
         any related Mortgaged Property, or in any such case an escrow of funds
         in an amount sufficient to cover such payments has been established.

                  (x) No Material Damage. As of the date of origination of such
         Mortgage Loan and, to the actual knowledge of the Depositor, as of the
         Closing Date, there was no pending proceeding for the total or partial
         condemnation of any related Mortgaged Property that materially affects
         the value thereof and such Mortgaged Property is free of material
         damage. Except for certain amounts not greater than amounts which would
         be considered prudent by an institutional commercial mortgage lender
         with respect to a similar mortgage loan and which are set forth in the
         related Mortgage or other loan documents relating to such Mortgage
         Loan, the related Mortgage Loan documents provide that any condemnation
         awards will be applied (or, at the discretion of the mortgagee, will be
         applied) to either the repair or restoration of all or part of the
         related Mortgaged Property or the reduction of the outstanding
         principal balance of such Mortgage Loan.

                                     -106-
<PAGE>

                  (xi) Title Insurance. Each related Mortgaged Property is
         covered by an ALTA (or its equivalent) lender's title insurance policy
         issued by a nationally recognized title insurance company, insuring
         that each related Mortgage is a valid first lien on such Mortgaged
         Property in the original principal amount of such Mortgage Loan (or, if
         such Mortgage Loan is part of a Loan Combination, in the original
         principal amount of such Loan Combination) after all advances of
         principal, subject only to Permitted Encumbrances and, in the case of a
         Lehman Trust Mortgage Loan that is part of a Loan Combination, further
         subject to the fact that the related Mortgage also secures the related
         Non-Trust Mortgage Loan(s) (or, if such policy has not yet been issued,
         such insurance may be evidenced by a binding commitment or binding pro
         forma marked as binding and signed (either thereon or on a related
         escrow letter attached thereto) by the title insurer or its authorized
         agent) from a title insurer qualified and/or licensed in the applicable
         jurisdiction, as required, to issue such policy; such title insurance
         policy is in full force and effect, all premiums have been paid, is
         freely assignable and will inure to the benefit of the Trustee as sole
         insured as mortgagee of record, or any such commitment or binding pro
         forma is a legal, valid and binding obligation of such insurer; no
         claims have been made by the Depositor or any prior holder of such
         Mortgage Loan under such title insurance policy; and neither the
         Depositor nor the applicable Lehman Mortgage Loan Seller (or any of its
         Affiliates) has done, by act or omission, anything that would
         materially impair the coverage of any such title insurance policy; such
         policy or commitment or binding pro forma contains no exclusion for (or
         alternatively it insures over such exclusion, unless such coverage is
         unavailable in the relevant jurisdiction) (A) access to a public road,
         (B) that there is no material encroachment by any improvements on the
         related Mortgaged Property either to or from any adjoining property or
         across any easements on the related Mortgaged Property, and (C) that
         the land shown on the survey materially conforms to the legal
         description of the related Mortgaged Property.

                  (xii) Property Insurance. As of the date of its origination
         and, to the Depositor's actual knowledge, as of the Cut-off Date, all
         insurance required under each related Mortgage (except where a tenant,
         having an investment grade rating, is permitted to insure or
         self-insure under a lease) was in full force and effect with respect to
         each related Mortgaged Property; such insurance included (A) fire and
         extended perils insurance included within the classification "All Risk
         of Physical Loss" or the equivalent thereof in an amount (subject to a
         customary deductible) at least equal to the lesser of (1) 100% of the
         full insurable replacement cost of the improvements located on such
         Mortgaged Property without reduction for depreciation (except to the
         extent not permitted by applicable law) and (2) the initial principal
         balance of such Mortgage Loan (or the portion thereof allocable to such
         Mortgaged Property), and if applicable, the related hazard insurance
         policies contain appropriate endorsements to avoid application of
         co-insurance, (B) business interruption or rental loss insurance for a
         period of not less than 12 months, (C) comprehensive general liability
         insurance in an amount not less than $1 million per occurrence, (D)
         workers' compensation insurance (if the related Mortgagor has employees
         and if required by applicable law), and (E) if (1) such Mortgage Loan
         is secured by a Mortgaged Property located in the State of California
         or in "seismic zone" 3 or 4 and (2) a seismic assessment as described
         below revealed a maximum probable or bounded loss in excess of 20% of
         the amount of the estimated replacement cost of the improvements on
         such Mortgaged Property, seismic insurance; it is an event of default
         under such Mortgage Loan if the above-described insurance coverage is
         not maintained by the related Mortgagor (except where a tenant, having
         an investment grade rating, is permitted to insure or self-insure under
         a lease) and the related loan documents provide that any reasonable
         out-of-pocket costs and expenses incurred by

                                     -107-
<PAGE>

         the mortgagee in connection with such default in obtaining such
         insurance coverage may be recovered from the related Mortgagor; the
         related Evidence of Property Insurance and certificate of liability
         insurance (which may be in the form of an Acord 27 or an Acord 25,
         respectively), or forms substantially similar thereto, provide that the
         related insurance policy may not be terminated or reduced without at
         least 10 days prior notice to the mortgagee and (other than those
         limited to liability protection) name the mortgagee and its successors
         as loss payee; no notice of termination or cancellation with respect to
         any such insurance policy has been received by the Depositor or the
         applicable Lehman Mortgage Loan Seller or, to the actual knowledge of
         Depositor, by any prior mortgagee under the subject Lehman Trust
         Mortgage Loan; all premiums under any such insurance policy have been
         paid through the Cut-off Date; the insurance policies specified in
         clauses (A), (B) and (C) above are required to be maintained with
         insurance companies having "financial strength" or "claims paying
         ability" ratings of at least "A:V" from A.M. Best Company or at least
         "A-" (or equivalent) from a nationally recognized statistical rating
         agency (or, with respect to certain blanket insurance policies, such
         other ratings as are in compliance with S&P's applicable criteria for
         rating the Certificates); and, except for certain amounts not greater
         than amounts which would be considered prudent by an institutional
         commercial mortgage lender with respect to a similar mortgage loan and
         which are set forth in the related Mortgage or other loan documents
         relating to such Mortgage Loan, and subject to the related exception
         schedules, the related Mortgage Loan documents provide that any
         property insurance proceeds will be applied (or, at the discretion of
         the mortgagee, will be applied) either to the repair or restoration of
         all or part of the related Mortgaged Property or the reduction of the
         outstanding principal balance of such Mortgage Loan; provided that the
         related Mortgage Loan documents may entitle the related Mortgagor to
         any portion of such proceeds remaining after completion of the repair
         or restoration of the related Mortgaged Property or payment of amounts
         due under such Mortgage Loan. If the related Mortgaged Property is
         located in the State of California or in "seismic zone" 3 or 4, then:
         (A) either a seismic assessment was conducted with respect to the
         related Mortgaged Property in connection with the origination of such
         Mortgage Loan or earthquake insurance was obtained; and (B) the
         probable maximum loss for the related Mortgaged Property as reflected
         in such seismic assessment, if any, was determined based upon a return
         period of not less than 475 years, an exposure period of 50 years and a
         10% probability of incidence. Schedule II-(xii) attached hereto is true
         and correct in all material respects.

                  (xiii) No Material Defaults. Other than payments due but not
         yet 30 days or more delinquent, there is (A) no material default,
         breach, violation or event of acceleration existing under the related
         Mortgage Note, the related Mortgage or other loan documents relating to
         such Mortgage Loan, and (B), to the knowledge of the Depositor, no
         event which, with the passage of time or with notice and the expiration
         of any grace or cure period, would constitute a material default,
         breach, violation or event of acceleration under any of such documents;
         provided, however, that this representation and warranty does not cover
         any default, breach, violation or event of acceleration (A) that
         specifically pertains to or arises out of the subject matter otherwise
         covered by any other representation and warranty made by the Seller in
         this Section 2.04(b) or (B) with respect to which: (1) neither the
         Depositor nor the applicable Lehman Mortgage Loan Seller has any actual
         knowledge and (2) written notice of the discovery thereof is not
         delivered to the Depositor by the Trustee or the Master Servicer on or
         prior to the date occurring twelve months after the Closing Date.
         Neither the Depositor nor any prior holder of the subject Lehman Trust
         Mortgage Loan has waived, in writing or with knowledge, any material
         default, breach, violation or event of acceleration under any of such
         documents. Under the terms

                                     -108-
<PAGE>

         of such Mortgage Loan, no person or party other than the mortgagee or
         its servicing agent may declare an event of default or accelerate the
         related indebtedness under such Mortgage Loan.

                  (xiv) No Payment Delinquency. As of the Closing Date, such
         Mortgage Loan is not, and in the prior 12 months (or since the date of
         origination if such Mortgage Loan has been originated within the past
         12 months), has not been, 30 days or more past due in respect of any
         Monthly Payment.

                  (xv) Interest Accrual Basis. Such Mortgage Loan accrues
         interest on an Actual/360 Basis, an Actual/Actual Basis or a 30/360
         Basis; and such Mortgage Loan accrues interest (payable monthly in
         arrears) at a fixed rate of interest throughout the remaining term
         thereof (except if such Mortgage Loan is an ARD Mortgage Loan, in which
         case the accrual rate for interest will increase after its Anticipated
         Repayment Date, and except in connection with the occurrence of a
         default and the accrual of default interest).

                  (xvi) Subordinate Debt. Each related Mortgage or other loan
         document relating to such Mortgage Loan does not provide for or permit,
         without the prior written consent of the holder of the related Mortgage
         Note, any related Mortgaged Property or any direct controlling interest
         in the Mortgagor to secure any other promissory note or debt (other
         than another Mortgage Loan in the Trust Fund and, if such Mortgage Loan
         is part of a Loan Combination, the other Mortgage Loan(s) that are part
         of such Loan Combination, as applicable).

                  (xvii) Qualified Mortgage. Such Mortgage Loan is a "qualified
         mortgage" within the meaning of Section 860G(a)(3) of the Code.
         Accordingly, either as of the date of origination or the Closing Date,
         the fair market value of the real property securing such Mortgage Loan
         was not less than 80% of the "adjusted issue price" (within the meaning
         of the REMIC Provisions) of such Mortgage Loan. For purposes of the
         preceding sentence, the fair market value of the real property securing
         such Mortgage Loan was first reduced by the amount of any lien on such
         real property that is senior to the lien that secures such Mortgage
         Loan, and was further reduced by a proportionate amount of any lien
         that is on a parity with the lien that secures such Mortgage Loan. No
         action that occurs by operation of the terms of such Mortgage Loan
         would cause such Mortgage Loan to cease to be a "qualified mortgage",
         and such Mortgage Loan does not permit the release or substitution of
         collateral if such release or substitution (A) would constitute a
         "significant modification" of such Mortgage Loan within the meaning of
         Treasury regulations section 1.1001-3, (B) would cause such Mortgage
         Loan not to be a "qualified mortgage" within the meaning of Section
         860G(a)(3) of the Code (without regard to clauses (A)(i) or (A)(ii)
         thereof) or (C) would cause a "prohibited transaction" within the
         meaning of Section 860F(a)(2) of the Code. The related Mortgaged
         Property, if acquired in connection with the default or imminent
         default of such Mortgage Loan, would constitute "foreclosure property"
         within the meaning of Section 860G(a)(8) of the Code.

                  (xviii) Prepayment Consideration. Prepayment Premiums and
         Yield Maintenance Charges payable with respect to such Mortgage Loan,
         if any, constitute "customary prepayment penalties" within the meaning
         of Treasury regulations section 1.860G-1(b)(2).

                  (xix) Environmental Conditions. One or more environmental site
         assessments (or updates thereof) in each instance meeting American
         Society of Testing and Materials requirements were performed by an
         environmental consulting firm independent of the Depositor

                                     -109-
<PAGE>

         and the Depositor's Affiliates with respect to each related Mortgaged
         Property during the 12-month period preceding the Cut-off Date, and the
         Depositor, having made no independent inquiry other than to review the
         report(s) prepared in connection with the assessment(s) and/or
         update(s) referenced herein, has no knowledge of, and has not received
         actual notice of, any material and adverse environmental condition or
         circumstance affecting such Mortgaged Property that was not disclosed
         in such report(s); none of the environmental reports reveal any
         circumstances or conditions that are in violation of any applicable
         environmental laws, or if such report does reveal such circumstances,
         then (1) the same have been remediated in all material respects, (2)
         sufficient funds have been escrowed or a letter of credit, guaranty or
         other instrument has been delivered for purposes of covering the
         estimated costs of such remediation, (3) the responsible party set
         forth on Schedule II-(xix) (which responsible party has been reasonably
         determined by the applicable Lehman Mortgage Loan Seller to have the
         creditworthiness to do so) is currently taking remedial or other
         appropriate action to address the environmental issue consistent with
         the recommendations in such site assessment, (4) the cost of the
         environmental issue relative to the value of such Mortgaged Property
         was de minimis, or (5) environmental insurance has been obtained.

                  The Mortgagor with respect to such Mortgage Loan has
         represented, warranted and covenanted generally to the effect that, to
         its knowledge, except as set forth in the environmental reports
         described above, it has not used, caused or permitted to exist, and
         will not use, cause or permit to exist, on the related Mortgaged
         Property, any Hazardous Materials in any manner which violates
         applicable federal, state or local laws governing the use, storage,
         handling, production or disposal of Hazardous Materials at the related
         Mortgaged Property and (A) the related Mortgagor and a natural person
         have agreed to indemnify the mortgagee under such Mortgage Loan, and
         its successor and assigns, against any losses, liabilities, damages,
         penalties, fines, claims and reasonable out-of-pocket expenses
         (excluding lost profits, consequential damages and diminution of value
         of the related Mortgaged Property, provided that no Lehman Trust
         Mortgage Loan with an original principal balance equal to or greater
         than $15,000,000 contains an exclusion for "diminution in value" of the
         related Mortgaged Property) paid, suffered or incurred by such
         mortgagee resulting from such Mortgagor's material violation of any
         environmental law or a material breach of the environmental
         representations and warranties or covenants given by the related
         Mortgagor in connection with such Mortgage Loan or (B) environmental
         insurance has been obtained. If such Mortgage Loan is a Mortgage Loan
         as to which neither a natural person has provided the indemnity set
         forth above nor environmental insurance has been obtained, such
         Mortgage Loan is set forth on Schedule II-(xix).

                  The Depositor has not taken any action with respect to such
         Mortgage Loan or the related Mortgaged Property that could subject the
         Depositor or its successors and assigns in respect of such Mortgage
         Loan to liability under CERCLA or any other applicable federal, state
         or local environmental law. The related Mortgage or other loan
         documents require the related Mortgagor to comply with all applicable
         federal, state and local environmental laws and regulations.

                  (xx) Realization Against Real Estate Collateral. The related
         Mortgage Note, Mortgage(s), Assignment(s) of Leases and other loan
         documents securing such Mortgage Loan, if any, contain customary and,
         subject to the limitations and exceptions as to enforceability in

                                     -110-
<PAGE>

         paragraph (b)(v) above, enforceable provisions such as to render the
         rights and remedies of the holder thereof adequate for the practical
         realization against the related Mortgaged Property or Properties of the
         principal benefits of the security intended to be provided thereby,
         including realization by judicial or, if applicable, non-judicial
         foreclosure.

                  (xxi) Bankruptcy. The related Mortgagor is not a debtor in any
         bankruptcy, reorganization, insolvency or comparable proceeding;
         provided, however, that this representation and warranty does not cover
         any such bankruptcy, reorganization, insolvency or comparable
         proceeding with respect to which: (1) neither the Depositor nor the
         applicable Lehman Mortgage Loan Seller has any actual knowledge and (2)
         written notice of the discovery thereof is not delivered to the
         Depositor by the Trustee or the Master Servicer on or prior to the date
         occurring twelve months after the Closing Date.

                  (xxii) Loan Security. Such Mortgage Loan is secured by a
         Mortgage on either a fee simple interest or a leasehold estate in a
         commercial property or multifamily property, including the related
         Mortgagor's interest in the improvements on the related Mortgaged
         Property.

                  (xxiii) Amortization. Such Mortgage Loan does not provide for
         negative amortization unless such Mortgage Loan is an ARD Mortgage
         Loan, in which case it may occur only after the Anticipated Repayment
         Date.

                  (xxiv) Whole Loan. Such Mortgage Loan is a whole loan,
         contains no equity participation by the lender or shared appreciation
         feature and does not provide for any contingent interest in the form of
         participation in the cash flow of the related Mortgaged Property.

                  (xxv) Due-on-Encumbrance. Each Lehman Trust Mortgage Loan
         contains provisions for the acceleration of the payment of the unpaid
         principal balance of such Mortgage Loan if, without the prior written
         consent of the mortgagee or Rating Agency confirmation that an Adverse
         Rating Event with respect to any Class of Certificates would not occur,
         any related Mortgaged Property, any direct interest therein or any
         direct controlling interest in the Mortgagor is directly encumbered in
         connection with subordinate financing; and, except in the case of a
         Lehman Trust Mortgage Loan that is part of a Loan Combination (for
         which such consent has been granted with respect to the related
         Non-Trust Mortgage Loan(s)), and except for the respective Lehman Trust
         Mortgage Loans secured by the Mortgaged Properties listed on Schedule
         II-(xxv) (for which such consent has been granted with respect to
         mezzanine debt), no such consent has been granted by the applicable
         Lehman Mortgage Loan Seller. To the Depositor's knowledge, no related
         Mortgaged Property is encumbered in connection with subordinate
         financing (except that each Mortgaged Property securing a Lehman Trust
         Mortgage Loan that is part of a Loan Combination also secures the
         related Non-Trust Mortgage Loan(s)); however, if the related Mortgaged
         Property is listed on Schedule II-(xxv), then certain direct
         controlling equity holders in the related Mortgagor are known to the
         Depositor to have incurred debt secured by their ownership interest in
         the related Mortgagor.

                  (xxvi) Due-on-Sale. Except with respect to transfers of
         certain non-controlling and/or minority interests in the related
         Mortgagor as specified in the related Mortgage or with respect to
         transfers of interests in the related Mortgagor between immediate
         family members and with respect to transfers by devise, by descent or
         by operation of law or otherwise upon the death

                                     -111-
<PAGE>

         or incapacity of a person having an interest in the related Mortgagor,
         each Lehman Trust Mortgage Loan contains either (A) provisions for the
         acceleration of the payment of the unpaid principal balance of such
         Mortgage Loan if any related Mortgaged Property or interest therein is
         directly or indirectly transferred or sold without the prior written
         consent of the mortgagee or rating agency confirmation, or (B)
         provisions for the acceleration of the payment of the unpaid principal
         balance of such Mortgage Loan if any related Mortgaged Property or
         interest therein is directly or indirectly transferred or sold without
         the related Mortgagor having satisfied certain conditions specified in
         the related Mortgage with respect to permitted transfers (which
         conditions are consistent with the practices of prudent commercial
         mortgage lenders). The Mortgage (under either specific or general
         expense provisions) requires the Mortgagor to pay all reasonable fees
         and expenses associated with securing the consent or approval of the
         holder of the Mortgage for all actions involving the transfer of
         interests in such Mortgagor or the related Mortgaged Property requiring
         such consent or approval under the Mortgage including the cost of any
         required counsel opinions relating to REMIC or other securitization and
         tax issues.

                  (xxvii) Mortgagor Concentration. Such Mortgage Loan, together
         with any other Lehman Trust Mortgage Loan made to the same Mortgagor or
         to an Affiliate of such Mortgagor, does not represent more than 5% of
         the Initial Pool Balance.

                  (xxviii) Waivers; Modifications. Except as set forth in a
         written instrument included in the related Mortgage File, the (A)
         material terms of the related Mortgage Note, the related Mortgage(s)
         and any related loan agreement and/or lock-box agreement have not been
         waived, modified, altered, satisfied, impaired, canceled, subordinated
         or rescinded by the mortgagee in any manner, and (B) no portion of a
         related Mortgaged Property has been released from the lien of the
         related Mortgage, in the case of (A) and/or (B), to an extent or in a
         manner that in any such event materially interferes with the security
         intended to be provided by such document or instrument. Schedule
         II-(xxviii) identifies each Lehman Trust Mortgage Loan as to which,
         since the latest date the related due diligence materials were
         delivered to Allied Capital Corporation, there has been given, made or
         consented to an alteration, modification or assumption of the terms of
         the related Mortgage Note, Mortgage(s) or any related loan agreement
         and/or lock-box agreement and/or as to which, since such date, there
         has been a waiver other than as related to routine operational matters
         or minor covenants.

                  (xxix) Inspection. Each related Mortgaged Property was
         inspected by or on behalf of the related originator during the
         six-month period prior to the related origination date.

                  (xxx) Property Release. The terms of the related Mortgage
         Note, Mortgage(s) or other loan document securing such Mortgage Loan do
         not provide for the release from the lien of such Mortgage of any
         portion of the related Mortgaged Property that is necessary to the
         operation of such Mortgaged Property or was given material value in the
         underwriting of such Mortgage Loan at origination, without (A) payment
         in full of such Mortgage Loan, (B) delivery of Defeasance Collateral in
         the form of "government securities" within the meaning of Section
         2(a)(16) of the Investment Company Act of 1940, as amended (the
         "Investment Company Act"), (C) payment of a release price equal to at
         least 125% of the amount of such Mortgage Loan allocated to the related
         Mortgaged Property or (D) the satisfaction of certain underwriting and
         legal requirements which would be considered reasonable by a prudent
         institutional commercial mortgage lender.

                                     -112-
<PAGE>

                  (xxxi) Qualifications; Licensing; Zoning. The related
         Mortgagor has covenanted in the related Mortgage Loan documents to
         maintain the related Mortgaged Property in compliance in all material
         respects with, to the extent it is not grandfathered under, all
         applicable laws, zoning ordinances, rules, covenants and restrictions
         affecting the construction, occupancy, use and operation of such
         Mortgaged Property, and the related originator performed the type of
         due diligence in connection with the origination of such Mortgage Loan
         customarily performed by prudent institutional commercial and
         multifamily mortgage lenders with respect to the foregoing matters; the
         Depositor has received no notice of any material violation of, to the
         extent is has not been grandfathered under, any applicable laws, zoning
         ordinances, rules, covenants or restrictions affecting the
         construction, occupancy, use or operation of the related Mortgaged
         Property (unless affirmatively covered by the title insurance referred
         to in paragraph (b)(xi) above (or an endorsement thereto)); to the
         Depositor's knowledge (based on surveys, opinions, letters from
         municipalities and/or title insurance obtained in connection with the
         origination of such Mortgage Loan), no improvement that was included
         for the purpose of determining the appraised value of the related
         Mortgaged Property at the time of origination of such Mortgage Loan lay
         outside the boundaries and building restriction lines of such property,
         in effect at the time of origination of such Mortgage Loan, to an
         extent which would have a material adverse affect on the related
         Mortgagor's use and operation of such Mortgaged Property (unless
         grandfathered with respect thereto or affirmatively covered by the
         title insurance referred to in paragraph (b)(xi) above (or an
         endorsement thereto)), and no improvements on adjoining properties
         encroached upon such Mortgaged Property to any material extent. For
         purposes of this paragraph, a Mortgaged Property shall be deemed
         "grandfathered" with respect to any laws, zoning ordinances, rules,
         covenants or restrictions affecting the construction, occupancy, use or
         operation of the related Mortgaged Property, if and to the extent that
         any of the construction, occupancy, use and operation of such Mortgaged
         Property: (A) conformed in all material respects with such laws, zoning
         ordinances, rules, covenants and restrictions affecting the
         improvements on the related Mortgaged Property at the time the
         improvements on the related Mortgaged Property were initially
         constructed or put into operation; and/or (B) was not addressed or
         otherwise prohibited by any such laws, zoning ordinances, rules,
         covenants and restrictions affecting the related Mortgaged Property at
         the time the improvements on the related Mortgaged Property were
         initially constructed or put into operation.

                  (xxxii) Property Financial Statements. The related Mortgagor
         has covenanted in the related Mortgage Loan documents to deliver to the
         mortgagee annual operating statements, rent rolls and related
         information of each related Mortgaged Property and annual financial
         statements. If such Mortgage Loan had an original principal balance
         greater than $3 million, then the related Mortgagor has covenanted to
         provide such operating statements, rent rolls and related information
         on a quarterly basis. If such Mortgage Loan has an original principal
         balance equal to or greater than $20 million, the related Mortgagor, if
         it obtains an audited financial statement, is required to provide a
         copy thereof to the holder of such Mortgage Loan at the related
         mortgagee's request.

                  (xxxiii) Single Purpose Entity. If such Mortgage Loan has a
         Cut-off Date Balance in excess of $25 million, then the related
         Mortgagor is obligated by its organizational documents and the related
         Mortgage Loan documents to be a Single Purpose Entity for so long as
         such Mortgage Loan is outstanding; and, if such Mortgage Loan has a
         Cut-off Date Balance greater than $5 million and less than $25 million,
         then the related Mortgagor is obligated by its

                                     -113-
<PAGE>

         organizational documents and/or the related Mortgage Loan documents to
         own the related Mortgaged Property and no other material assets, except
         such as are incidental to the ownership of such Mortgaged Property for
         so long as such Mortgage Loan is outstanding. For purposes of this
         representation, "Single Purpose Entity" means an entity whose
         organizational documents or the related Mortgage Loan documents provide
         substantially to the effect that such entity: (A) is formed or
         organized solely for the purpose of owning and operating one or more of
         the Mortgaged Properties securing such Mortgage Loan, (B) may not
         engage in any business unrelated to the related Mortgaged Property or
         Mortgaged Properties, (C) does not have any material assets other than
         those related to its interest in and operation of such Mortgaged
         Property or Mortgaged Properties and (D) may not incur indebtedness
         other than as permitted by the related Mortgage or other Mortgage Loan
         documents. If such Mortgage Loan has an initial principal balance of
         $25 million and above and the related Mortgagor is a single member
         limited liability company, such Mortgagor's organizational documents
         provide that such Mortgagor shall not dissolve or liquidate upon the
         bankruptcy, dissolution, liquidation or death of its sole member and is
         organized in a jurisdiction that provides for such continued existence
         and there was obtained opinion of counsel confirming such continued
         existence. If such Mortgage Loan has, or is part of a group of Lehman
         Trust Mortgage Loans with affiliated Mortgagors having, a Cut-off Date
         Balance equal to or greater than 2% of the Initial Pool Balance, or if
         such Mortgage Loan has an original principal balance equal to or
         greater than $25 million, there was obtained an opinion of counsel
         regarding non-consolidation of such Mortgagor.

                  (xxxiv) Advancing of Funds. No advance of funds has been made,
         directly or indirectly, by the originator or the Depositor to the
         related Mortgagor other than pursuant to the related Mortgage Note;
         and, to the actual knowledge of the Depositor, no funds have been
         received from any Person other than such Mortgagor for or on account of
         payments due on the related Mortgage Note.

                  (xxxv) Legal Proceedings. To the Depositor's actual knowledge,
         there are no pending actions, suits or proceedings by or before any
         court or governmental authority against or affecting the related
         Mortgagor or any related Mortgaged Property that, if determined
         adversely to such Mortgagor or Mortgaged Property, would materially and
         adversely affect the value of such Mortgaged Property or the ability of
         such Mortgagor to pay principal, interest or any other amounts due
         under such Mortgage Loan.

                  (xxxvi) Originator Duly Authorized. To the extent required
         under applicable law as of the Closing Date, the originator of such
         Mortgage Loan was qualified and authorized to do business in each
         jurisdiction in which a related Mortgaged Property is located at all
         times when it held such Mortgage Loan to the extent necessary to ensure
         the enforceability of such Mortgage Loan.

                  (xxxvii) Trustee under Deed of Trust. If the related Mortgage
         is a deed of trust, a trustee, duly qualified under applicable law to
         serve as such, is properly designated and serving under such Mortgage,
         and no fees and expenses are payable to such trustee except in
         connection with a trustee sale of the related Mortgaged Property
         following a default or in connection with the release of liens securing
         such Mortgage Loan and any such fees and expenses are the obligation of
         the Mortgagor under the terms of the Mortgage.

                                     -114-

                  (xxxviii) Cross-Collateralization. The related Mortgaged
         Property is not, to the Depositor's knowledge, collateral or security
         for any mortgage loan that is not in the Trust Fund, and if such
         Mortgage Loan is cross-collateralized, it is cross-collateralized only
         with other Mortgage Loans in the Trust Fund, except that a Lehman Trust
         Mortgage Loan that is part of a Loan Combination is secured by one or
         more Mortgaged Properties that also secure the related Non-Trust
         Mortgage Loan(s). The security interest/lien on each material item of
         collateral for such Mortgage Loan has been assigned to the Trustee.

                  (xxxix) Flood Hazard Insurance. None of the improvements on
         any related Mortgaged Property are located in a flood hazard area as
         defined by the Federal Insurance Administration or, if any portion of
         the improvements on the related Mortgaged Property are in an area
         identified in the Federal Register by the Federal Emergency Management
         Agency as having special flood hazards falling within zones A or V in
         the national flood insurance program, the Mortgagor has obtained and is
         required to maintain flood insurance.

                  (xl) Engineering Assessments. One or more engineering
         assessments or updates of a previously conducted engineering assessment
         were performed by an Independent engineering consulting firm with
         respect to each related Mortgaged Property during the 12-month period
         preceding the Cut-off Date, and the Depositor, having made no
         independent inquiry other than to review the report(s) prepared in
         connection with such assessment(s) and or update(s), does not have any
         knowledge of any material and adverse engineering condition or
         circumstance affecting such Mortgaged Property that was not disclosed
         in such report(s); and, to the extent such assessments revealed
         deficiencies, deferred maintenance or similar conditions, either (A)
         the estimated cost has been escrowed or a letter of credit has been
         provided, (B) repairs have been made or (C) the scope of the deferred
         maintenance relative to the value of such Mortgaged Property was de
         minimis.

                  (xli) Escrows. All escrow deposits and payments relating to
         such Mortgage Loan are under control of the Depositor or the servicer
         of such Mortgage Loan and all amounts required as of the date hereof
         under the related Mortgage Loan documents to be deposited by the
         related Mortgagor have been deposited. The Depositor is transferring to
         the Trustee all of its right, title and interest in and to such
         amounts.

                  (xlii) Licenses, Permits and Authorizations. The related
         Mortgagor has represented in the related Mortgage Loan documents that,
         and to the actual knowledge of the Depositor, as of the date of
         origination of such Mortgage Loan, all material licenses, permits and
         authorizations then required for use of the related Mortgaged Property
         by such Mortgagor, the related lessee, franchisor or operator have been
         issued and were valid and in full force and effect.

                  (xliii) Origination, Servicing and Collection Practices. The
         origination, servicing and collection practices used by the Depositor
         or any prior holder of the related Mortgage Note with respect to such
         Mortgage Loan have been in all respects legal and have met customary
         industry standards.

                  (xliv) Fee Simple. Unless such Mortgage Loan is covered by the
         representation and warranty in the immediately following paragraph
         (xlv), such Mortgage Loan is secured in whole or in material part by a
         fee simple interest.

                                     -115-

                  (xlv) Leasehold Interest Only. If such Mortgage Loan is
         secured in whole or in material part by the interest of the related
         Mortgagor as a lessee under a Ground Lease but not by the related fee
         interest, then:

                           (A)      such Ground Lease or a memorandum thereof
                                    has been or will be duly recorded and such
                                    Ground Lease permits the interest of the
                                    lessee thereunder to be encumbered by the
                                    related Mortgage or, if consent of the
                                    lessor thereunder is required, it has been
                                    obtained prior to the Closing Date;

                           (B)      upon the foreclosure of such Mortgage Loan
                                    (or acceptance of a deed in lieu thereof),
                                    the Mortgagor's interest in such Ground
                                    Lease is assignable to the Trustee without
                                    the consent of the lessor thereunder (or, if
                                    any such consent is required, it has been
                                    obtained prior to the Closing Date) and, in
                                    the event that it is so assigned, is further
                                    assignable by the Trustee and its successors
                                    without a need to obtain the consent of such
                                    lessor (or, if any such consent is required,
                                    it has been obtained prior to the Closing
                                    Date or may not be unreasonably withheld);

                           (C)      such Ground Lease may not be amended or
                                    modified without the prior written consent
                                    of the mortgagee under such Mortgage Loan
                                    and any such action without such consent is
                                    not binding on such mortgagee, its
                                    successors or assigns;

                           (D)      unless otherwise set forth in such Ground
                                    Lease, such Ground Lease does not permit any
                                    increase in the amount of rent payable by
                                    the ground lessee thereunder during the term
                                    of such Mortgage Loan;

                           (E)      such Ground Lease was in full force and
                                    effect as of the date of origination of the
                                    related Mortgage Loan and, at the Closing
                                    Date, such Ground Lease is in full force and
                                    effect; to the actual knowledge of the
                                    Seller, except for payments due but not yet
                                    30 days or more delinquent, (1) there is no
                                    material default under such Ground Lease,
                                    and (2) there is no event which, with the
                                    passage of time or with notice and the
                                    expiration of any grace or cure period,
                                    would constitute a material default under
                                    such Ground Lease;

                           (F)      such Ground Lease, or an estoppel or consent
                                    letter received by the mortgagee under such
                                    Mortgage Loan from the lessor, requires the
                                    lessor thereunder to give notice of any
                                    default by the lessee to such mortgagee; and
                                    such Ground Lease, or an estoppel or consent
                                    letter received by the mortgagee under such
                                    Mortgage Loan from the lessor, further
                                    provides either (1) that no notice of
                                    termination given under such Ground Lease is
                                    effective against such mortgagee unless a
                                    copy has been delivered to the mortgagee in
                                    the manner described in such Ground Lease,
                                    estoppel or consent letter or (2) that upon
                                    any termination of such Ground Lease the
                                    lessor will enter into a new lease with such
                                    mortgagee upon such mortgagee's request;

                                     -116-
<PAGE>

                           (G)      based upon the related policy of title
                                    insurance, the ground lessee's interest in
                                    such Ground Lease is not subject to any
                                    liens or encumbrances superior to, or of
                                    equal priority with, the related Mortgage,
                                    other than the related ground lessor's
                                    related fee interest and any Permitted
                                    Encumbrances;

                           (H)      the mortgagee under such Mortgage Loan is
                                    permitted a reasonable opportunity to cure
                                    any curable default under such Ground Lease
                                    (not less than the time provided to the
                                    related lessee under such ground lease to
                                    cure such default) before the lessor
                                    thereunder may terminate or cancel such
                                    Ground Lease;

                           (I)      such Ground Lease has a currently effective
                                    term (including any options exercisable by
                                    the holder of the related Mortgage) that
                                    extends not less than 20 years beyond the
                                    Stated Maturity Date of the related Mortgage
                                    Loan;

                           (J)      under the terms of such Ground Lease, any
                                    estoppel or consent letter received by the
                                    mortgagee under such Mortgage Loan from the
                                    lessor and the related Mortgage Loan
                                    documents, taken together, any related
                                    insurance proceeds, other than de minimis
                                    amounts for minor casualties, with respect
                                    to the leasehold interest, or condemnation
                                    proceeds will be applied either to the
                                    repair or restoration of all or part of the
                                    related Mortgaged Property, with the
                                    mortgagee or a trustee appointed by it
                                    having the right to hold and disburse such
                                    proceeds as the repair or restoration
                                    progresses (except in such cases where a
                                    provision entitling another party to hold
                                    and disburse such proceeds would not be
                                    viewed as commercially unreasonable by a
                                    prudent commercial mortgage lender), or to
                                    the payment of the outstanding principal
                                    balance of the Mortgage Loan, together with
                                    any accrued interest thereon;

                           (K)      such Ground Lease does not impose any
                                    restrictions on use or subletting which
                                    would be viewed as commercially unreasonable
                                    by a prudent commercial mortgage lender;

                           (L)      upon the request of the mortgagee under such
                                    Mortgage Loan, the ground lessor under such
                                    Ground Lease is required to enter into a new
                                    lease upon termination of the Ground Lease

                                    Ground Lease following notice thereof from

                  (xlvi) Fee Simple and Leasehold Interest. If such Mortgage
         Loan is secured by the interest of the related Mortgagor under a Ground
         Lease and by the related fee interest, then (A) such fee interest is
         subject, and subordinated of record, to the related Mortgage, (B) the

         the related Mortgage by the related Mortgagor, the mortgagee under such
         Mortgage Loan has the right (subject to the limitations and exceptions

                  (xlviii) Defeasance. If such Mortgage Loan is a Defeasance
         Mortgage Loan, the related Mortgage Loan documents require the related
         Mortgagor to pay all reasonable costs associated with the defeasance
         thereof, and either: (A) require the prior written consent of, and
         compliance with the conditions set by, the holder of such Mortgage Loan
         for defeasance or (B) require that (1) defeasance may not occur prior

         all scheduled payments under the related Mortgage Note when due
         (assuming for each ARD Mortgage Loan that it matures on its Anticipated
         Repayment Date or on the date when any open prepayment period set forth
         in the related Mortgage Loan documents commences) or, in the case of a
         partial defeasance that effects the release of a material portion of
         the related Mortgaged Property, to make all scheduled payments under
         the related Mortgage Note on that part of such Mortgage Loan equal to
         at least 110% of the allocated loan amount of the portion of the
         Mortgaged Property being released, (3) an independent accounting firm

         of such Mortgage Loan (or by the Mortgagor with the approval of such
         lender), and (5) counsel provide an opinion letter to the effect that
         the Trustee has a perfected security interest in such Defeasance
         Collateral prior to any other claim or interest.

                  (xlix) Primary Servicing Rights. No Person has been granted or
         conveyed the right to primary service such Mortgage Loan or receive any
         consideration in connection therewith except (A) as contemplated in

         to the Depositor's knowledge, as of the Closing Date, (A) the related
         Mortgaged Property is free and clear of any and all mechanics' and
         materialmen's liens that are not bonded, insured against or escrowed
         for, and (B) no rights are outstanding that under law could give rise
         to any such lien that would be prior or equal to the lien of the
         related Mortgage (unless affirmatively covered by

                                     -118-
<PAGE>

         the title insurance referred to in paragraph (b)(xi) above (or an
         endorsement thereto)). The Depositor has not received actual notice

         Encumbrances, the related Assignment of Leases set forth in or separate
         from the related Mortgage and delivered in connection with such
         Mortgage Loan establishes and creates a valid and, subject only to the
         exceptions and limitations in paragraph (b)(v) above, enforceable first
         priority lien and first priority security interest in the related
         Mortgagor's right to receive payments due under any and all leases,
         subleases, licenses or other agreements pursuant to which any Person is
         entitled to occupy, use or possess all or any portion of the related
         Mortgaged Property subject to the related Mortgage, except that a
         license may have been granted to the related Mortgagor to exercise
         certain rights and perform certain obligations of the lessor under the
         relevant lease or leases; and each assignor thereunder has the full
         right to assign the same.

         Mortgagor other than as the holder of such Mortgage Loan being sold and

         satisfied in full, and except as expressly contemplated by the related
         loan agreement or other documents contained in the related Mortgage
         File, no material portion of the related Mortgaged Property has been
         released.

                  (lvii) Usury. Such Mortgage Loan complied with or was exempt

                                    expenses reasonably related to the operation
                                    of the related Mortgaged Property, amounts
                                    due for reserves established under such
                                    Mortgage Loan, and payments for any other
                                    expenses, including capital expenses,

                           (C)      no later than the related Anticipated
                                    Repayment Date, the related Mortgagor is
                                    required (if it has not previously done so)
                                    to enter into a "lockbox agreement" whereby
                                    all revenue from the related Mortgaged
                                    Property will be deposited directly into a

                                     -123-

be required to execute on behalf of the Trustee in connection with the
defeasance of a Mortgage Loan as contemplated in this Agreement. Subject to
Section 3.10, the Trustee shall, at the written request of the Master Servicer
or the Special Servicer, promptly execute any limited powers of attorney and
other documents furnished by the Master Servicer or the Special Servicer that
are necessary or appropriate to enable them to carry out their servicing and
administrative duties hereunder; provided, however, that the Trustee shall not
be held liable for any misuse of any such power of attorney by the Master
Servicer or the Special Servicer. Notwithstanding anything contained herein to
the contrary, neither the Master Servicer nor the Special Servicer shall,
without the Trustee's written consent: (i) initiate any action, suit or
proceeding solely under the Trustee's name without indicating the Master
Servicer's or Special Servicer's, as applicable, representative capacity; or
(ii) take any action with the intent to cause, and that actually causes, the
Trustee to be registered to do business in any state.

         (c) The parties hereto acknowledge that the MGM Tower Loan Pair is
subject to the terms and conditions of the MGM Tower Co-Lender Agreement. The
parties hereto further recognize the respective rights and obligations of the
MGM Tower Noteholders under the MGM Tower Co-Lender Agreement, including with
respect to (i) the allocation of collections on or in respect of the MGM Tower
Loan Pair, and the making of payments, to the MGM Tower Noteholders in
accordance with Section 4.01 of the MGM Tower Co-Lender Agreement, (ii) the
allocation of expenses and losses relating to the MGM Tower Loan Pair to the MGM
Tower Noteholders in accordance with Section 4.02 of the MGM Tower Co-Lender
Agreement, (iii) the purchase of the MGM Tower Trust Mortgage Loan by the MGM
Tower Non-Trust Mortgage Loan Noteholder or its designee in accordance with
Section 4.03 of the MGM Tower Co-Lender Agreement, and (iv) the right of the MGM
Tower Non-Trust Mortgage Loan Noteholder or its designee to cure certain events
of default occurring with respect to the MGM Tower Trust Mortgage Loan in
accordance with Sections 7.01 and 7.02 of the MGM Tower Co-Lender Agreement.

         In the event that neither the MGM Tower Trust Mortgage Loan nor any
related REO Property is an asset of the Trust Fund and the servicing and
administration of the MGM Tower Loan Pair and any related REO Property is to be
governed by a separate servicing agreement and not by this Agreement, as
contemplated by Section 3.01 of the MGM Tower Co-Lender Agreement, the Master
Servicer and, if the MGM Tower Loan Pair is then being specially serviced
hereunder or the MGM Tower Mortgaged Property has become an REO Property, the
Special Servicer, shall continue to act in such capacities under such separate
servicing agreement, which agreement shall be reasonably acceptable to the
Master Servicer and/or the Special Servicer, as the case may be, and shall
contain servicing and administration, limitation of liability, indemnification
and servicing compensation provisions substantially similar to the corresponding
provisions of this Agreement, except for the fact that the MGM Tower Loan Pair
and the MGM Tower Mortgaged Property shall be the sole assets serviced and
administered thereunder and the sole source of funds thereunder.

         If at any time, neither the MGM Tower Trust Mortgage Loan nor any
related REO Property is an asset of the Trust Fund, and if a separate servicing
agreement with respect to the MGM Tower Loan Pair or any REO Property, as
applicable, has not been entered into as contemplated by Section 3.01 of the MGM
Tower Co-Lender Agreement, and notwithstanding that neither the MGM Tower Trust
Mortgage Loan nor any related REO Property is an asset of the Trust Fund, then
the Master Servicer and, if applicable, the Special Servicer shall continue to
service and administer the MGM Tower Loan Pair and/or any related REO Property,
for the benefit of the respective holders of such Loan Combination, under this
Agreement as if the MGM Tower Loan Pair or any related REO Property were

                                     -124-
<PAGE>

the sole assets subject hereto, with certain references in this Agreement
applicable to the Trust, the Trustee, the Certificates, the Certificateholders
(or any subgroup thereof) or any representative of any such Certificates, all
being construed to refer to such similar terms as are applicable to the then
current holder of the Mortgage Note for the MGM Tower Trust Mortgage Loan.

         (d) The parties hereto acknowledge that the GIC Office Loan Group is
subject to the terms and conditions of the GIC Office Co-Lender Agreement. The
parties hereto further recognize the respective rights and obligations of the
GIC Office Noteholders under the GIC Office Co-Lender Agreement, including with
respect to: (i) the allocation of collections on or in respect of the GIC Office
Loan Group, and the making of payments, to the GIC Office Noteholders in
accordance with Section 4.01 of the GIC Office Co-Lender Agreement, (ii) the
allocation of expenses and losses relating to the GIC Office Loan Group to the
GIC Office Noteholders in accordance with Section 4.02 of the GIC Office
Co-Lender Agreement, (iii) the sharing of certain expenses in accordance with
Section 4.05 of the GIC Office Co-Lender Agreement, (iv) the purchase of the GIC
Office Trust Mortgage Loan (together with the GIC Office Pari Passu Non-Trust
Mortgage Loans) by the GIC Office Subordinate Non-Trust Mortgage Loan Noteholder
or its designee in accordance with Section 4.03 of the GIC Office Co-Lender
Agreement, and (v) the right of the GIC Office Subordinate Non-Trust Mortgage
Loan Noteholder or a designee thereof to cure certain events of default
occurring with respect to the GIC Office Note A Mortgage Loans in accordance
with Sections 7.01 and 7.02 of the GIC Office Co-Lender Agreement.

         In the event that neither the GIC Office Trust Mortgage Loan nor any
related REO Property is an asset of the Trust Fund and the servicing and
administration of the GIC Office Loan Group and any related REO Property is to
be governed by a separate servicing agreement and not by this Agreement, as
contemplated by Section 3.01 of the GIC Office Co-Lender Agreement, the Master
Servicer and, if the GIC Office Loan Group is then being specially serviced
hereunder or the GIC Office Mortgaged Property has become an REO Property, the
Special Servicer, shall continue to act in such capacities under such separate
servicing agreement, which agreement shall be reasonably acceptable to the
Master Servicer and/or the Special Servicer, as the case may be, and shall
contain servicing and administration, limitation of liability, indemnification
and servicing compensation provisions substantially similar to the corresponding
provisions of this Agreement, except for the fact that the GIC Office Loan Group
and the GIC Office Mortgaged Property shall be the sole assets serviced and
administered thereunder and the sole source of funds thereunder. Prior to
entering into a separate servicing agreement in accordance with the foregoing
sentence, the "Lead Lender" (as defined in the GIC Office Co-Lender Agreement)
is required to provide the GIC Office Pari Passu Non-Trust Mortgage Loan
Noteholders with written confirmation from each applicable nationally recognized
statistical rating organization then rating any GIC Office Pari Passu Non-Trust
Mortgage Loan Securities, that the servicing and administration of the GIC
Office Loan Group and/or any GIC Office REO Property under such new servicing
agreement will not result in an Adverse Rating Event.

         If at any time, neither the GIC Office Trust Mortgage Loan nor any
related REO Property is an asset of the Trust Fund, and if a separate servicing
agreement with respect to the GIC Office Loan Group or any REO Property, as
applicable, has not been entered into as contemplated by Section 3.01 of the GIC
Office Co-Lender Agreement (or the rating agency confirmation referred to in the
last sentence of the preceding paragraph has not been received), and
notwithstanding that neither the GIC Office Trust Mortgage Loan nor any related
REO Property is an asset of the Trust Fund, then the Master Servicer and, if
applicable, the Special Servicer shall continue to service and administer the
GIC Office Loan

                                     -125-
<PAGE>

Group and/or any related REO Property, for the benefit of the respective holders
of such Loan Combination, under this Agreement as if the GIC Office Loan Group
or any related REO Property were the sole assets subject hereto, with certain
references in this Agreement applicable to the Trust, the Trustee, the
Certificates, the Certificateholders (or any subgroup thereof) or any
representative of any such Certificateholders, all being construed to refer to
such similar terms as are applicable to the then current holder of the Mortgage
Note for the GIC Office Trust Mortgage Loan.

         (e) The Master Servicer shall use efforts consistent with the Servicing
Standard to have prepared, executed and delivered by the applicable party (and
included in the Servicing File), not later than the later of (i) 30 days
following the Master Servicer's receipt of the subject franchisor comfort
letter, guaranty of payment or letter of credit and (ii) the expiration of the
period that may be required for such transfer or assignment pursuant to the
terms of the applicable franchisor comfort letter, guaranty of payment or letter
of credit, if any, (A) with respect to any Mortgage Loan secured by a
hospitality property (and with respect to which a franchise agreement
constitutes part of the related Mortgage File on the Closing Date), any original
transfer or assignment documents necessary to transfer or assign to the Trustee
any rights under the related franchisor comfort letter; and (B) with respect to
any Mortgage Loan that has a related guaranty or letter of credit that
constitutes part of the related Mortgage File on the Closing Date, any original
transfer or assignment documents necessary to transfer or assign to the Trustee
any rights under the related guaranty of payment or letter of credit. In the
event, with respect to a Trust Mortgage Loan with a related letter of credit, it
is determined by the Master Servicer that a draw under such letter of credit has
become necessary under the terms thereof prior to the assignment under clause
(B) of the preceding sentence having been effected, the Master Servicer shall
direct (in writing) the Depositor (in the case of a Lehman Trust Mortgage Loan)
or the UBS Mortgage Loan Seller (in the case of a UBS Trust Mortgage Loan) to
make such draw or to cause such draw to be made on behalf of the Trustee, and,
the Depositor will, and the UBS Mortgage Loan Seller will be obligated under the
UBS/Depositor Mortgage Loan Purchase Agreement to, use its best efforts to cause
such draw to be made; provided that neither the Depositor nor the UBS Mortgage
Loan Seller shall have any liability in connection with the determination to
make, or the making of, such draw (other than to remit the proceeds of such draw
to the Master Servicer).

         (f) The relationship of each of the Master Servicer and the Special
Servicer to the Trustee, to the Non-Trust Mortgage Loan Noteholders and to each
other under this Agreement is intended by the parties to be that of an
independent contractor and not that of a joint venturer, partner or agent.

         SECTION 3.02. Collection of Mortgage Loan Payments.

         (a) Each of the Master Servicer and the Special Servicer shall
undertake reasonable efforts to collect all payments required under the terms
and provisions of the Mortgage Loans it is obligated to service hereunder and
shall follow such collection procedures as are consistent with the Servicing
Standard; provided, however, that neither the Master Servicer nor the Special
Servicer shall, with respect to any ARD Mortgage Loan after its Anticipated
Repayment Date, take any enforcement action with respect to the payment of
Additional Interest (other than the making of requests for its collection),
unless (i) the taking of an enforcement action with respect to the payment of
other amounts due under such ARD Mortgage Loan is, in the good faith and
reasonable judgment of the Special Servicer, necessary, appropriate and
consistent with the Servicing Standard or (ii) all other amounts due under such
ARD Mortgage Loan have been paid, the payment of such Additional Interest has
not been

                                     -126-
<PAGE>

forgiven in accordance with Section 3.20 and, in the good faith and reasonable
judgment of the Special Servicer, the Liquidation Proceeds expected to be
recovered in connection with such enforcement action will cover the anticipated
costs of such enforcement action and, if applicable, any associated interest
accrued on Advances. The Special Servicer shall ensure that, with respect to
Specially Serviced Mortgage Loans, the Mortgagors make payments directly to the
Master Servicer; provided that, in the event the Special Servicer receives a
payment that should have been made directly to the Master Servicer, the Special
Servicer shall promptly forward such payment to the Master Servicer. Upon
receipt of any such payment with respect to a Specially Serviced Mortgage Loan,
the Master Servicer shall promptly notify the Special Servicer, and the Special
Servicer shall direct the Master Servicer as to the proper posting of such
payment. Consistent with the foregoing, the Special Servicer, with regard to a
Specially Serviced Mortgage Loan, or the Master Servicer, with regard to a
Performing Mortgage Loan, may waive or defer any Default Charges in connection
with collecting any late payment on a Mortgage Loan; provided that without the
consent of the Special Servicer in the case of a proposed waiver by the Master
Servicer, no such waiver or deferral may be made by the Master Servicer pursuant
to this Section 3.02 if any Advance has been made as to such delinquent payment.

         (b) All amounts received with respect to any Cross-Collateralized Group
in the form of payments from Mortgagors, Insurance Proceeds, Condemnation
Proceeds and Liquidation Proceeds, shall be applied by the Master Servicer among
the Trust Mortgage Loans constituting such Cross-Collateralized Group in
accordance with the express provisions of the related loan documents and, in the
absence of such express provisions or to the extent that such payments and other
collections may be applied at the discretion of the lender, on a pro rata basis
in accordance with the respective amounts then "due and owing" as to each such
Mortgage Loan. Except in the case of the GIC Office Trust Mortgage Loan or the
MGM Tower Trust Mortgage Loan, amounts received in respect of or allocable to
any particular Trust Mortgage Loan (whether or not such Trust Mortgage Loan
constitutes part of a Cross-Collateralized Group) in the form of payments from
Mortgagors, Liquidation Proceeds, Condemnation Proceeds or Insurance Proceeds
shall be applied to amounts due and owing under the related Mortgage Note and
Mortgage (including for principal and accrued and unpaid interest) in accordance
with the express provisions of the related Mortgage Note and Mortgage and, in
the absence of such express provisions or to the extent that such payments and
other collections may be applied at the discretion of the lender, as follows:
first, as a recovery of any related unpaid servicing expenses and unreimbursed
Servicing Advances; second, as a recovery of accrued and unpaid interest on such
Trust Mortgage Loan at the related Mortgage Rate to, but not including, the date
of receipt (or, in the case of a full Monthly Payment from any Mortgagor,
through the related Due Date), exclusive, however, in the case of an ARD Trust
Mortgage Loan after its Anticipated Repayment Date, of any such accrued and
unpaid interest that constitutes Additional Interest; third, as a recovery of
principal of such Trust Mortgage Loan then due and owing, including by reason of
acceleration of such Trust Mortgage Loan following a default thereunder (or, if
a Liquidation Event has occurred in respect of such Trust Mortgage Loan, as a
recovery of principal to the extent of its entire remaining unpaid principal
balance); fourth, unless a Liquidation Event has occurred with respect to such
Trust Mortgage Loan, as a recovery of amounts to be currently applied to the
payment of, or escrowed for the future payment of, real estate taxes,
assessments, insurance premiums (including premiums on any Environmental
Insurance Policy), ground rents (if applicable) and similar items; fifth, unless
a Liquidation Event has occurred with respect to such Trust Mortgage Loan, as a
recovery of Reserve Funds to the extent then required to be held in escrow;
sixth, as a recovery of any Prepayment Premium or Yield Maintenance Charge then
due and owing under such Trust Mortgage Loan; seventh, as a recovery of any
Default Charges then due and owing under such Trust Mortgage Loan; eighth, as a
recovery of any assumption fees, modification fees

                                     -127-
<PAGE>

and extension fees then due and owing under such Trust Mortgage Loan; ninth, as
a recovery of any other amounts then due and owing under such Trust Mortgage
Loan (other than remaining unpaid principal and, in the case of an ARD Trust
Mortgage Loan after its Anticipated Repayment Date, other than Additional
Interest); tenth, as a recovery of any remaining principal of such Trust
Mortgage Loan to the extent of its entire remaining unpaid principal balance;
and, eleventh, in the case of an ARD Trust Mortgage Loan after its Anticipated
Repayment Date, as a recovery of accrued and unpaid Additional Interest on such
ARD Trust Mortgage Loan to but not including the date of receipt; provided that,
if one or more Advances previously made in respect of a Trust Mortgage Loan have
been reimbursed out of general collections of principal on the Mortgage Pool as
one or more Nonrecoverable Advances, then collections in respect of such Trust
Mortgage Loan available for application pursuant to clauses second through
eleventh of this sentence shall instead be applied in the following order--(i)
as a recovery of accrued and unpaid interest on, and principal of, such Trust
Mortgage Loan, to the extent of any outstanding P&I Advances and unpaid Master
Servicing Fees in respect of such Trust Mortgage Loan, (ii) as a recovery of the
item(s) for which such previously reimbursed Nonrecoverable Advance(s) were made
(together with, but only if a Liquidation Event has occurred with respect to
such Trust Mortgage Loan, any interest on such previously reimbursed
Nonrecoverable Advance(s) that was also paid out of general collections of
principal on the Mortgage Pool), and (iii) in accordance with clauses second
through eleventh of this sentence (taking into account the applications pursuant
to clauses (i) and (ii) of this proviso).

         All amounts received with respect to a Loan Combination shall be
applied to amounts due and owing under the Mortgage Loans comprising such Loan
Combination (including for principal and accrued and unpaid interest) in
accordance with the express provisions of the related Mortgage Notes, the
related Mortgage, the related loan agreement, if any, and the related Co-Lender
Agreement.

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

         (a) The Master Servicer shall, as to all of the Mortgage Loans,
establish and maintain one or more accounts (the "Servicing Accounts"), in which
all related Escrow Payments shall be deposited and retained; provided that, in
the case of a Loan Combination, if the related Servicing Account includes funds
with respect to any other Mortgage Loan, then the Master Servicer shall maintain
a separate sub-account of such Servicing Account that relates solely to such
Loan Combination. Subject to the terms of the related loan documents, each
Servicing Account shall be an Eligible Account. Withdrawals of amounts so
collected from a Servicing Account may be made (in each case, to the extent of
amounts on deposit therein in respect of the related Mortgage Loan or, in the
case of clauses (iv) and (v) below, to the extent of interest or other income
earned on such amounts) only for the following purposes: (i) consistent with the
related loan documents, to effect the payment of real estate taxes, assessments,
insurance premiums (including premiums on any Environmental Insurance Policy),
ground rents (if applicable) and comparable items in respect of the respective
Mortgaged Properties; (ii) insofar as the particular Escrow Payment represents a
late payment that was intended to cover an item described in the immediately
preceding clause (i) for which a Servicing Advance was made, to reimburse the
Master Servicer, the Special Servicer, the Trustee or the Fiscal Agent, as
applicable, for such Servicing Advance; (iii) to refund to Mortgagors any sums
as may be determined to be overages; (iv) following an event of default under
the related Mortgage Loan, for such other purposes as are consistent with the
related loan documents, applicable law and the Servicing Standard; (v) to pay
interest, if required and as described below, to Mortgagors on balances in such
Servicing Account; (vi)

                                     -128-
<PAGE>

to pay the Master Servicer interest and investment income on balances in such
Servicing Account as described in Section 3.06, if and to the extent not
required by law or the terms of the related loan documents to be paid to the
Mortgagor; or (vii) to clear and terminate such Servicing Account at the
termination of this Agreement in accordance with Section 9.01. To the extent
permitted by law or the applicable loan documents, funds in the Servicing
Accounts may be invested only in Permitted Investments in accordance with the
provisions of Section 3.06. The Master Servicer shall pay or cause to be paid to
the Mortgagors interest, if any, earned on the investment of funds in the
related Servicing Accounts, if required by law or the terms of the related
Mortgage Loan. If the Master Servicer shall deposit in a Servicing Account any
amount not required to be deposited therein, it may at any time withdraw such
amount from such Servicing Account, any provision herein to the contrary
notwithstanding.

         (b) The Master Servicer shall, as to each and every Mortgage Loan, (i)
maintain accurate records with respect to the related Mortgaged Property
reflecting the status of real estate taxes, assessments and other similar items
that are or may become a lien thereon and the status of insurance premiums and
any ground rents payable in respect thereof and (ii) use reasonable efforts to
obtain, from time to time, all bills for (or otherwise confirm) the payment of
such items (including renewal premiums) and, if the subject Mortgage Loan
requires the related Mortgagor to escrow for such items, shall effect payment
thereof prior to the applicable penalty or termination date. For purposes of
effecting any such payment for which it is responsible, the Master Servicer
shall apply Escrow Payments as allowed under the terms of the related Mortgage
Loan (or, if such Mortgage Loan does not require the related Mortgagor to escrow
for the payment of real estate taxes, assessments, insurance premiums, ground
rents (if applicable) and similar items, the Master Servicer shall use
reasonable efforts consistent with the Servicing Standard to cause the related
Mortgagor to comply with the requirement of the related Mortgage that the
Mortgagor make payments in respect of such items at the time they first become
due and, in any event, prior to the institution of foreclosure or similar
proceedings with respect to the related Mortgaged Property for nonpayment of
such items). Subject to Section 3.11(h), the Master Servicer shall timely make a
Servicing Advance to cover any such item which is not so paid, including any
penalties or other charges arising from the Mortgagor's failure to timely pay
such items.

         (c) The Master Servicer shall, as to each and every Mortgage Loan, make
a Servicing Advance with respect to the related Mortgaged Property in an amount
equal to all such funds as are necessary for the purpose of effecting the
payment of (i) real estate taxes, assessments and other similar items, (ii)
ground rents (if applicable), and (iii) premiums on Insurance Policies
(including Environmental Insurance Policies), in each instance if and to the
extent Escrow Payments (if any) collected from the related Mortgagor are
insufficient to pay such item when due and the related Mortgagor (or any related
guarantor or party entitled to exercise cure rights) has failed to pay such item
on a timely basis. All such Servicing Advances shall be reimbursable in the
first instance from related payments by or on behalf of the Mortgagors, and
further as provided in Section 3.05(a), Section 3.05A and/or Section 3.05B. No
costs incurred by the Master Servicer in effecting the payment of real estate
taxes, assessments and, if applicable, ground rents on or in respect of the
Mortgaged Properties shall, for purposes of this Agreement, including the
Trustee's calculation of monthly distributions to Certificateholders, be added
to the unpaid Stated Principal Balances of the related Mortgage Loans,
notwithstanding that the terms of such Mortgage Loans so permit. The foregoing
shall in no way limit the Master Servicer's ability to charge and collect from
the Mortgagor such costs together with interest thereon.

                                     -129-
<PAGE>

         (d) The Master Servicer shall, as to all Mortgage Loans, establish and
maintain, as applicable, one or more accounts (the "Reserve Accounts"), into
which all related Reserve Funds, if any, shall be deposited and retained;
provided that, in the case of a Loan Combination, if the related Reserve Account
includes funds with respect to any other Mortgage Loan, then the Master Servicer
shall maintain a separate sub-account of such Reserve Account that relates
solely to such Loan Combination. Withdrawals of amounts so deposited may be made
(i) for the specific purposes for which the particular Reserve Funds were
delivered, in accordance with the Servicing Standard and the terms of the
related Mortgage Note, Mortgage and any other agreement with the related
Mortgagor governing such Reserve Funds, (ii) to pay the Master Servicer interest
and investment income earned on amounts in the Reserve Accounts as described
below, and (iii) following an event of default under the related Mortgage Loan,
for such other purposes as are consistent with the related loan documents,
applicable law and the Servicing Standard. To the extent permitted in the
applicable loan documents, funds in the Reserve Accounts may be invested in
Permitted Investments in accordance with the provisions of Section 3.06. Subject
to the related loan documents, all Reserve Accounts shall be Eligible Accounts.
Consistent with the Servicing Standard, the Master Servicer may waive or extend
the date set forth in any agreement governing Reserve Funds by which any
required repairs, capital improvements and/or environmental remediation at the
related Mortgaged Property must be completed; provided that any waiver, any
extension for more than 120 days and any subsequent extension may only be
granted with the consent of the Special Servicer.

         SECTION 3.04. Pool Custodial Account, Defeasance Deposit Account,
                       Collection Account, Interest Reserve Account and Excess
                       Liquidation Proceeds Account.

         (a) The Master Servicer shall establish and maintain one or more
separate accounts (collectively, the "Pool Custodial Account"), in which the
amounts described in clauses (i) through (x) below (which shall not include any
amounts allocable to the Non-Trust Mortgage Loans) shall be deposited and held
on behalf of the Trustee in trust for the benefit of the Certificateholders. The
Pool Custodial Account shall be an Eligible Account. The Master Servicer shall
deposit or cause to be deposited in the Pool Custodial Account, within one (1)
Business Day of receipt (in the case of payments by Mortgagors or other
collections on the Trust Mortgage Loans) or as otherwise required hereunder, the
following payments and collections received or made by the Master Servicer or on
its behalf subsequent to the Cut-off Date (other than in respect of principal
and interest on the Trust Mortgage Loans due and payable on or before the
Cut-off Date, which amounts shall be delivered promptly to the Depositor or its
designee, with negotiable instruments endorsed as necessary and appropriate
without recourse, and other than amounts required to be deposited in the
Defeasance Deposit Account), or any of the following payments (other than
Principal Prepayments) received by it on or prior to the Cut-off Date but
allocable to a period subsequent thereto:

                  (i) all payments on account of principal of the Trust Mortgage
         Loans, including Principal Prepayments, and regardless of whether those
         payments are made by the related Mortgagor, any related guarantor or
         any party exercising cure rights under any related co-lender,
         intercreditor or similar agreement, out of any related Reserve Funds
         maintained for such purpose, out of collections on any related
         Defeasance Collateral or from any other source;

                  (ii) all payments on account of interest on the Trust Mortgage
         Loans, including Default Interest and Additional Interest, and
         regardless of whether those payments are

                                     -130-
<PAGE>

         made by the related Mortgagor, any related guarantor or any party
         exercising cure rights under any related co-lender, intercreditor or
         similar agreement, out of any related Reserve Funds maintained for such
         purpose, out of collections on any related Defeasance Collateral or
         from any other source;

                  (iii) all Prepayment Premiums, Yield Maintenance Charges and
         late payment charges received in respect of any Trust Mortgage Loan;

                  (iv) all Insurance Proceeds, Condemnation Proceeds and
         Liquidation Proceeds received in respect of any Trust Mortgage Loan or,
         except to the extent such proceeds are to first be deposited in an REO
         Account, any REO Property;

                  (v) any amounts representing a reimbursement, payment and/or
         contribution due and owing to the Trust from any Non-Trust Mortgage
         Loan Noteholder in accordance with the related Co-Lender Agreement;

                  (vi) any amounts required to be deposited by the Master

         with respect to Permitted Investments of funds held in the Pool
         Custodial Account;

                  (vii) any amounts required to be deposited by the Master
         Servicer or the Special Servicer pursuant to Section 3.07(b) in
         connection with losses on the Mortgage Pool resulting from a deductible
         clause in a blanket hazard policy;

                  (viii) any amounts required to be transferred from the GIC

         pursuant to Section 3.16(c);

                  (ix) insofar as they do not constitute Escrow Payments, any
         amounts paid by a Mortgagor with respect to a Trust Mortgage Loan

         made; and

                  (x) the Initial Deposit;

provided that any amounts described in clauses (i) through (iv), (vii) and (ix)

pursuant to the GIC Office Co-Lender Agreement, the sale of the MGM Tower Trust
Mortgage Loan to or through the MGM Tower Non-Trust Mortgage Loan Noteholder
pursuant to the MGM Tower Co-Lender Agreement, the purchase of the GIC Office
Trust Mortgage Loan, the MGM Tower Trust Mortgage Loan or the Trust's interest
in any related REO Property by the Depositor in connection with a Material
Breach or a Material Document Defect pursuant to Section 2.03 or the sale of the
GIC Office Trust Mortgage Loan or the MGM Tower Trust Mortgage Loan as a
Specially Serviced Trust Mortgage Loan pursuant to Section 3.18) shall be
deposited in the applicable Loan Combination Custodial Account, and, in any such
case, shall thereafter be transferred to the Pool Custodial Account as provided
in Section 3.05A or Section 3.05B, as applicable, together with any other
amounts required to be

                                     -131-
<PAGE>

transferred from such Loan Combination Custodial Account to the Pool Custodial
Account from time to time pursuant to Section 3.05A or Section 3.05B, as
applicable.

         The foregoing requirements for deposit in the Pool Custodial Account
shall be exclusive. Notwithstanding the foregoing, actual payments from
Mortgagors in the nature of Escrow Payments, Reserve Funds, assumption fees,
assumption application fees, funds representing a Mortgagor's payment of costs
and expenses associated with assumptions and defeasance, modification fees,
extension fees, charges for beneficiary statements or demands, amounts collected
for checks returned for insufficient funds and any similar fees (other than
Prepayment Consideration) not expressly referred to in the prior paragraph need
not be deposited by the Master Servicer in the Pool Custodial Account. If the
Master Servicer shall deposit in the Pool Custodial Account any amount not
required to be deposited therein, it may at any time withdraw such amount from
the Pool Custodial Account, any provision herein to the contrary
notwithstanding. The Master Servicer shall promptly deliver to the Special
Servicer, as additional special servicing compensation in accordance with
Section 3.11(d), all assumption fees and assumption application fees (or the
applicable portions thereof), and other transaction fees received by the Master
Servicer to which the Special Servicer is entitled pursuant to such section upon
receipt of a written statement (on which the Master Servicer is entitled to
rely) of a Servicing Officer of the Special Servicer describing the item and
amount (unless pursuant to this Agreement it is otherwise clear that the Special
Servicer is entitled to such amounts, in which case a written statement is not
required). The Pool Custodial Account shall be maintained as a segregated
account, separate and apart from trust funds created for mortgage-backed
securities of other series and the other accounts of the Master Servicer.

         Upon receipt of any of the amounts described in clauses (i) through (v)
and (ix) of the second preceding paragraph with respect to any Trust Mortgage
Loan (other than a Trust Mortgage Loan that is part of a Loan Combination), the
Special Servicer shall promptly, but in no event later than two (2) Business
Days after receipt, remit such amounts to the Master Servicer for deposit into
the Pool Custodial Account in accordance with the second preceding paragraph,
unless the Special Servicer determines, consistent with the Servicing Standard,
that a particular item should not be deposited because of a restrictive
endorsement or other appropriate reason. With respect to any such amounts paid
by check to the order of the Special Servicer, the Special Servicer shall
endorse such check to the order of the Master Servicer, unless the Special
Servicer determines, consistent with the Servicing Standard, that a particular
item cannot be so endorsed and delivered because of a restrictive endorsement or
other appropriate reason. Any such amounts received by the Special Servicer with
respect to an REO Property (other than an REO Property that relates to a Loan
Combination) shall be deposited by the Special Servicer into the Pool REO
Account and thereafter remitted to the Master Servicer for deposit into the Pool
Custodial Account as and to the extent provided in Section 3.16(c).

         If and when any Mortgagor under a Defeasance Mortgage Loan elects to
defease all or any part of its Mortgage Loan and, pursuant to the provisions of
the related loan documents, delivers cash to the Master Servicer to purchase the
required Defeasance Collateral, the Master Servicer shall establish and maintain
one or more separate segregated accounts (collectively, the "Defeasance Deposit
Account"), in which the Master Servicer shall deposit such cash within one (1)
Business Day of receipt by the Master Servicer. The Master Servicer shall retain
such cash in the Defeasance Deposit Account pending its prompt application to
purchase Defeasance Collateral. The Master Servicer shall hold such cash and
maintain the Defeasance Deposit Account on behalf of the Trustee and, in the
case of a Loan Combination, the related Non-Trust Mortgage Loan Noteholder(s),
to secure payment on the related Defeasance Mortgage Loan. The Defeasance
Deposit Account shall be an Eligible Account. To the

                                     -132-
<PAGE>

extent permitted by law or the applicable Defeasance Mortgage Loan, prior to the
purchase of Defeasance Collateral, funds in the Defeasance Deposit Account may
be invested only in Permitted Investments in accordance with the provisions of
Section 3.06. The Master Servicer shall pay or cause to be paid to the related
Mortgagor(s) interest, if any, earned on the investment of funds in the
Defeasance Deposit Account, if required by law or the terms of the related
Defeasance Mortgage Loan(s).

         (b) The Trustee shall establish and maintain one or more trust accounts
(collectively, the "Collection Account") to be held in trust for the benefit of
the Certificateholders. Each account that constitutes the Collection Account
shall be an Eligible Account. The Trustee shall establish and maintain, on a
book-entry basis, the Class V Sub-Account, which sub-account shall be deemed to
be held in trust for the benefit of the Holders of the Class V Certificates. The
Master Servicer shall deliver to the Trustee each month on or before the Trust
Master Servicer Remittance Date therein, for deposit in the Collection Account,
an aggregate amount of immediately available funds equal to the Master Servicer
Remittance Amount for such Trust Master Servicer Remittance Date, together with,
in the case of the Final Distribution Date, any additional amounts contemplated
by the second paragraph of Section 9.01. Immediately upon deposit of the Master
Servicer Remittance Amount for any Trust Master Servicer Remittance Date into
the Collection Account, any portion thereof that represents Additional Interest
shall be deemed to have been deposited into the Class V Sub-Account.

         In addition, the Master Servicer shall, as and when required hereunder,
deliver to the Trustee (without duplication) for deposit in the Collection
Account:

                  (i) any P&I Advances required to be made by the Master
         Servicer in accordance with Section 4.03(a); and

                  (ii) any amounts required to be deposited by the Master
         Servicer pursuant to Section 3.19(a) in connection with Prepayment
         Interest Shortfalls.

         The Trustee shall, upon receipt, deposit in the Collection Account any
and all amounts received by it that are required by the terms of this Agreement
to be deposited therein.

         In the event that the Master Servicer fails, on any Trust Master
Servicer Remittance Date, to remit to the Trustee any amount(s) required to be
so remitted to the Trustee hereunder by such date, the Master Servicer shall pay
the Trustee, for the account of the Trustee, interest, calculated at the Prime
Rate, on such amount(s) not timely remitted, from and including that Trust
Master Servicer Remittance Date, to but not including the related Distribution
Date.

         On the Trust Master Servicer Remittance Date in March of each year
(commencing in March 2004), the Trustee shall transfer from the Interest Reserve
Account to the Collection Account all Interest Reserve Amounts then on deposit
in the Interest Reserve Account with respect to the Interest Reserve Mortgage
Loans and any Interest Reserve REO Mortgage Loans.

         As and when required pursuant to Section 3.05(d), the Trustee shall
transfer monies from the Excess Liquidation Proceeds Account to the Collection
Account.

         (c) The Trustee shall establish and maintain one or more accounts
(collectively, the "Interest Reserve Account"), to be held in trust for the
benefit of the Certificateholders, for purposes of

                                     -133-
<PAGE>

holding the Interest Reserve Amounts in respect of the Interest Reserve Mortgage
Loans and any Interest Reserve REO Mortgage Loans. Each account that constitutes
the Interest Reserve Account shall be an Eligible Account. On each Distribution
Date in February and, during a year that is not a leap year, in January, prior
to any distributions being made in respect of the Certificates on such
Distribution Date, the Trustee shall withdraw from the Collection Account and
deposit in the Interest Reserve Account with respect to each Interest Reserve
Mortgage Loan and Interest Reserve REO Mortgage Loan, an amount equal to the
Interest Reserve Amount, if any, in respect of such Mortgage Loan or REO
Mortgage Loan, as the case may be, for such Distribution Date; provided that no
such transfer of funds shall occur if the subject Distribution Date is the Final
Distribution Date. Subject to the next paragraph, the Interest Reserve Account
may be a sub-account of the Collection Account.

         Notwithstanding that the Interest Reserve Account may be a sub-account
of the Collection Account for reasons of administrative convenience, the
Interest Reserve Account and the Collection Account shall, for all purposes of
this Agreement (including the obligations and responsibilities of the Trustee
hereunder), be considered to be and shall be required to be treated as, separate
and distinct accounts. The Trustee shall indemnify and hold harmless the Trust
Fund against any losses arising out of the failure by the Trustee to perform its
duties and obligations hereunder as if such accounts were separate accounts. The
provisions of this paragraph shall survive any resignation or removal of the
Trustee and appointment of a successor trustee.

         (d) If any Excess Liquidation Proceeds are received on the Mortgage
Pool, the Trustee shall establish and maintain one or more accounts
(collectively, the "Excess Liquidation Proceeds Account") to be held in trust
for the benefit of the Certificateholders, for purposes of holding such Excess
Liquidation Proceeds. Each account that constitutes the Excess Liquidation
Proceeds Account shall be an Eligible Account. On each Trust Master Servicer
Remittance Date, the Master Servicer shall withdraw from the Pool Custodial
Account and remit to the Trustee for deposit in the Excess Liquidation Proceeds
Account all Excess Liquidation Proceeds received with respect to the Mortgage
Pool during the Collection Period ending in the calendar month in which such
Trust Master Servicer Remittance Date occurs. Subject to the next paragraph, the
Excess Liquidation Proceeds Account may be a sub-account of the Collection
Account.

         Notwithstanding that the Excess Liquidation Proceeds Account may be a
sub-account of the Collection Account for reasons of administrative convenience,
the Excess Liquidation Proceeds Account and the Collection Account shall, for
all purposes of this Agreement (including the obligations and responsibilities
of the Trustee hereunder), be considered to be and shall be required to be
treated as, separate and distinct accounts. The Trustee shall indemnify and hold
harmless the Trust Fund against any losses arising out of the failure by the
Trustee to perform its duties and obligations hereunder as if such accounts were
separate accounts. The provisions of this paragraph shall survive any
resignation or removal of the Trustee and appointment of a successor trustee.

         (e) Funds in the Pool Custodial Account (exclusive of the Initial
Deposit) may be invested only in Permitted Investments in accordance with the
provisions of Section 3.06. The Initial Deposit and funds in the Collection
Account, the Interest Reserve Account and the Excess Liquidation Proceeds
Account shall remain uninvested. The Master Servicer shall give notice to the
Trustee, the Special Servicer and the Rating Agencies of the location of the
Pool Custodial Account as of the Closing Date and of the new location of the
Pool Custodial Account prior to any change thereof. As of the Closing Date, the
Collection Account, the Interest Reserve Account and the Excess Liquidation

                                     -134-
<PAGE>

Proceeds Account shall be located at the Trustee's offices in Chicago, Illinois.
The Trustee shall give notice to the Master Servicer, the Special Servicer and
the Rating Agencies of any change in the location of the Collection Account, the
Interest Reserve Account or the Excess Liquidation Proceeds Account prior to any
change thereof.

         (a) The Master Servicer shall establish and maintain, with respect to
the GIC Office Loan Group, one or more separate accounts (collectively, the "GIC
Office Custodial Account") in which the amounts described in clauses (i) through
(ix) below shall be deposited and held in trust for the benefit of the holders
of the Mortgage Notes for the GIC Office Loan Group, as their interests may
appear; provided that, subject to the last paragraph of this Section 3.04A(a), a
GIC Office Custodial Account may be a sub-account of the Pool Custodial Account.
The GIC Office Custodial Account shall be an Eligible Account or, subject to the
last paragraph of this Section 3.04A(a), a sub-account of an Eligible Account.
The Master Servicer shall deposit or cause to be deposited in the GIC Office
Custodial Account, within one (1) Business Day of receipt (in the case of
payments or other collections on the GIC Office Loan Group) or as otherwise
required hereunder, the following payments and collections received or made by
the Master Servicer or on its behalf with respect to the GIC Office Loan Group
subsequent to the Cut-off Date (other than in respect of principal and interest

Deposit Account):

                  (i) all payments on account of principal of the GIC Office
         Loan Group, including Principal Prepayments, and regardless of whether
         those payments are made by the related Mortgagor, any related
         guarantor, or any party exercising cure rights under the GIC Office
         Co-Lender Agreement or any related mezzanine intercreditor agreement,

         on any related Defeasance Collateral or from any other source;

                  (iii) all Prepayment Premiums, Yield Maintenance Charges

         Trust's interest in any related REO Property by the Depositor in
         connection with a Material Breach or a Material Document Defect
         pursuant to Section 2.03 or the sale of the GIC Office Trust Mortgage
         Loan as a Specially Serviced Trust Mortgage Loan pursuant to Section
         3.18);

<PAGE>

                  (v) any amounts required to be deposited by the Master
         Servicer pursuant to Section 3.06 in connection with losses incurred
         with respect to Permitted Investments of funds held in the GIC Office
         Custodial Account;

                  (vi) any amounts required to be deposited by the Master
         Servicer or the Special Servicer pursuant to Section 3.07(b) in
         connection with losses with respect to the GIC Office Loan Group
         resulting from a deductible clause in a blanket hazard policy;

                  (vii) any amounts required to be transferred from the GIC
         Office REO Account pursuant to Section 3.16(c);

         amounts paid by the related Mortgagor with respect to the GIC Office
         Loan Group specifically to cover items for which a Servicing Advance
         has been made; and

                  (ix) any amounts representing a reimbursement, payment and/or
         contribution due and owing to a party other than the Trust from any GIC
         Office Non-Trust Mortgage Loan Noteholder in accordance with the GIC
         Office Co-Lender Agreement.

         The foregoing requirements for deposit in the GIC Office Custodial
Account shall be exclusive. Notwithstanding the foregoing, actual payments from
the related Mortgagor in respect of the GIC Office Loan Group in the nature of
Escrow Payments, Reserve Funds, assumption fees, assumption application fees,
funds representing such Mortgagor's payment of costs and expenses associated
with assumptions and defeasance, modification fees, extension fees, charges for
beneficiary statements or demands, amounts collected for checks returned for
insufficient funds and any similar fees to which the Master Servicer or Special
Servicer is entitled as additional servicing compensation and that are not
expressly referred to in the prior paragraph, need not be deposited by the
Master Servicer in the GIC Office Custodial Account. If the Master Servicer
shall deposit into the GIC Office Custodial Account any amount not required to
be deposited therein, then it may at any time withdraw such amount from such
Custodial Account, any provision herein to the contrary notwithstanding. The
Master Servicer shall promptly deliver to the Special Servicer, as additional
special servicing compensation in accordance with Section 3.11(d), all
assumption fees and assumption application fees (or the applicable portions
thereof) and other transaction fees received by the Master Servicer with respect
to the GIC Office Loan Group, to which the Special Servicer is entitled pursuant
to such section, upon receipt of a written statement of a Servicing Officer of
the Special Servicer describing the item and amount (unless pursuant to this
Agreement it is otherwise clear that the Special Servicer is entitled to such
amounts, in which case a written statement is not required). The GIC Office
Custodial Account shall be maintained as a segregated account, separate and
apart from trust funds created for mortgage-backed securities of other series
and the other accounts of the Master Servicer.

         Upon receipt of any of the amounts described in clauses (i) through
(iv), (viii) and (ix) of the second preceding paragraph with respect to the GIC
Office Loan Group, the Special Servicer shall promptly, but in no event later
than two (2) Business Days after receipt, remit such amounts to the Master
Servicer for deposit into the GIC Office Custodial Account in accordance with
the second preceding paragraph, unless the Special Servicer determines,
consistent with the Servicing Standard, that a particular item should not be
deposited because of a restrictive endorsement or other appropriate reason. With
respect to any such amounts paid by check to the order of the Special Servicer,
the Special Servicer shall endorse such check to the order of the Master
Servicer, unless the Special Servicer

                                     -136-
<PAGE>

determines, consistent with the Servicing Standard, that a particular item
cannot be so endorsed and delivered because of a restrictive endorsement or
other appropriate reason. Any such amounts received by the Special Servicer with
respect to an REO Property that relates to the GIC Office Loan Group shall
initially be deposited by the Special Servicer into the GIC Office REO Account
and thereafter remitted to the Master Servicer for deposit into the GIC Office
Custodial Account, all in accordance with Section 3.16(c).

         Notwithstanding that the GIC Office Custodial Account may be a
sub-account of the Pool Custodial Account for reasons of administrative
convenience, the GIC Office Custodial Account and the Pool Custodial Account
shall, for all purposes of this Agreement (including the obligations and
responsibilities of the Master Servicer hereunder), be considered to be and
shall be required to be treated as, separate and distinct accounts. The Master
Servicer shall indemnify and hold harmless the Trust Fund and the GIC Office
Non-Trust Mortgage Loan Noteholders against any losses arising out of the
failure by the Master Servicer to perform its duties and obligations hereunder
as if such accounts were separate accounts. The provisions of this paragraph
shall survive any resignation or removal of the Master Servicer and appointment
of a successor master servicer.

         (b) If and when the related Mortgagor elects to defease the GIC Office
Loan Group or any portion thereof, the provisions of the last paragraph of
Section 3.04(a) relating to the Defeasance Deposit Account shall apply.

         (c) The Master Servicer shall give notice to the Trustee, the GIC
Office Non-Trust Mortgage Loan Noteholders and the Special Servicer of the
location of the GIC Office Custodial Account when first established and of the
new location of the GIC Office Custodial Account prior to any change thereof.

of the Mortgage Notes for the MGM Tower Loan Pair, as their interests may

         Mortgage Loan pursuant to Section 3.18);

                  (v) any amounts required to be deposited by the Master

         The foregoing requirements for deposit in the MGM Tower Custodial
Account shall be exclusive. Notwithstanding the foregoing, actual payments from
the related Mortgagor in respect of the MGM Tower Loan Pair in the nature of
Escrow Payments, Reserve Funds, assumption fees, assumption application fees,
funds representing such Mortgagor's payment of costs and expenses associated

Custodial Account any amount not required to be deposited therein, then it may
at any time withdraw such amount from such Custodial Account, any provision
herein to the contrary notwithstanding. The Master Servicer shall promptly
deliver to the Special Servicer, as additional special servicing compensation in

other appropriate reason. Any such amounts received by the Special Servicer with
respect to an REO Property that relates to the MGM Tower Loan Pair shall
initially be deposited by the Special Servicer into the MGM Tower REO Account
and thereafter remitted to the Master Servicer for deposit into the MGM Tower
Custodial Account, all in accordance with Section 3.16(c).

         Notwithstanding that the MGM Tower Custodial Account may be a
sub-account of the Pool Custodial Account for reasons of administrative
convenience, the MGM Tower Custodial Account and the Pool Custodial Account
shall, for all purposes of this Agreement (including the obligations and
responsibilities of the Master Servicer hereunder), be considered to be and
shall be required to be treated as, separate and distinct accounts. The Master
Servicer shall indemnify and hold harmless the Trust Fund and the MGM Tower
Non-Trust Mortgage Loan Noteholder against any losses arising out of the failure
by the Master Servicer to perform its duties and obligations hereunder as if
such accounts were separate accounts. The provisions of this paragraph shall
survive any resignation or removal of the Master Servicer and appointment of a
successor master servicer.

         (b) If and when the related Mortgagor elects to defease the MGM Tower
Loan Pair, the provisions of the last paragraph of Section 3.04(a) relating to
the Defeasance Deposit Account shall apply.

         (c) The Master Servicer shall give notice to the Trustee, the MGM Tower
Non-Trust Mortgage Loan Noteholder and the Special Servicer of the location of
the MGM Tower Custodial Account when first established and of the new location
of the MGM Tower Custodial Account prior to any change thereof.

Servicing Officer of the Special Servicer or of a Responsible Officer of the
Trustee or the Fiscal Agent describing the item and amount to which the Special
Servicer (or such third party contractor), the Trustee or the Fiscal Agent, as
applicable, is entitled (unless such payment to the Special Servicer, the
Trustee (for example, the Trustee Fee) or the Fiscal Agent, as the case may be,
is clearly required pursuant to this Agreement, in which case a written
statement is not required). The Master Servicer may rely conclusively on any

         In connection with any payments required to be made to a Non-Trust
Mortgage Loan Noteholder in accordance with Section 3.05(a)(xvii), the Master
Servicer may request a written statement from such Non-Trust Mortgage Loan

reasonably rely upon such statement as the nature and amount of the item for
which reimbursement is sought.

         The Special Servicer shall keep and maintain separate accounting for
each Specially Serviced Trust Mortgage Loan and REO Property, on a loan-by-loan
basis, for the purpose of justifying any request for withdrawal from the Pool
Custodial Account. With respect to each Trust Mortgage Loan for which it makes
an Advance, each of the Trustee and Fiscal Agent shall keep and maintain
separate accounting, on a loan-by-loan basis, for the purpose of justifying any
request for withdrawal from the Pool Custodial Account for reimbursements of
Advances or payments of interest thereon.

                  (iii) to pay, out of general collections on the Mortgage Pool

         to be made pursuant to this clause (xi) out of: first, amounts on

         principal of the MGM Tower Non-Trust Mortgage Loan or any successor REO
         Mortgage Loan with respect thereto, with such payment to be deducted in
         accordance with Section 4.02 of the MGM Tower Co-Lender Agreement from
         the amounts so distributable; and, second, any other amounts on deposit
         in the MGM Tower Custodial Account that would otherwise be payable
         under the MGM Tower Co-Lender Agreement to the MGM Tower Noteholders on

         or both of the MGM Tower Mortgage Loans or any successor REO Mortgage
         Loans with respect thereto, and a corresponding deduction from the
         amounts otherwise payable to either or both of the MGM Tower

         extent of the Net Investment Earnings with respect to the MGM Tower
         Custodial Account for any Trust Collection Period;

                  (xiii) to pay itself, the Special Servicer, or any of their
         respective members, managers, directors, officers, employees and

         pursuant to Section 6.03, to the extent such amounts relate to the MGM
         Tower Loan Pair, any such payment (in accordance with the MGM Tower
         Co-Lender Agreement) to be made pursuant to this clause (xiii) out of:
         first, amounts on deposit in the MGM Tower Custodial Account that would
         otherwise be distributable under the MGM Tower Co-Lender Agreement to

         with respect thereto, with such payment to be deducted in accordance
         with Section 4.02 of the MGM Tower Co-Lender Agreement from the amounts
         so distributable; and, second, any other amounts on deposit in the MGM
         Tower Custodial Account that would otherwise be payable under the MGM

         a corresponding allocation of such payment to either or both of the MGM
         Tower Mortgage Loans or any successor REO Mortgage Loans with respect
         thereto, and a corresponding deduction from the amounts otherwise
         payable to either or both of the MGM Tower Noteholders on the relevant

                  (xiv) to pay (out of amounts otherwise payable thereto under
         the MGM Tower Co-Lender Agreement on any MGM Tower Master Servicer
         Remittance Date) each MGM Tower Noteholder's share of the cost of
         recording the MGM Tower Co-Lender Agreement in accordance with Section
         6.02(a) of the MGM Tower Co-Lender Agreement;

                  (xv) to pay for the cost of recording this Agreement and the
         cost of any corresponding Opinion of Counsel, insofar as such
         recordation is for the benefit of the MGM Tower Noteholders, any such
         payment (in accordance with the MGM Tower Co-Lender Agreement) to be
         made pursuant to this clause (xv) out of: first, amounts on deposit in
         the MGM Tower Custodial Account that would otherwise be distributable

         the amounts so distributable; and, second, any other amounts on deposit
         in the MGM Tower Custodial Account that would otherwise be payable

         any MGM Tower Master Servicer Remittance Date (with, if and to the
         extent applicable, a corresponding allocation of such payment to either
         or both of the MGM Tower Mortgage Loans or any successor REO Mortgage
         Loans with respect thereto, and a corresponding deduction from the
         amounts otherwise payable to either or both of the MGM Tower
         Noteholders on the relevant MGM Tower Master Servicer Remittance Date,
         all in accordance with Section 4.02 of the MGM Tower Co-Lender
         Agreement);

                  (xvi) to the extent (A) consistent with the MGM Tower
         Co-Lender Agreement and (B) not otherwise included among the payments
         contemplated by clause (i) of this Section 3.05B, to transfer to the
         Pool Custodial Account the aggregate of all Additional Trust Fund
         Expenses and/or any other amounts relating to the MGM Tower Loan Pair,
         that have been previously paid out of the Pool Custodial Account
         pursuant to Section 3.05(a) and that, if not previously paid out of the
         Pool Custodial Account in accordance with Section 3.05(a), would have
         been otherwise payable from the MGM Tower Custodial Account under this
         Section 3.05B;

                  (xvii) to reimburse any amounts paid by the MGM Tower
         Non-Trust Mortgage Loan Noteholder to cure defaults under the MGM Tower
         Trust Mortgage Loan, the MGM Tower Non-Trust Mortgage Loan Noteholder's
         right to reimbursement under this clause (xviii) to be limited to
         amounts on deposit in the MGM Tower Custodial Account that represent
         collections on the MGM Tower Loan Pair that are in excess of all
         amounts (including Monthly Payments and

                                     -158-
<PAGE>

         Assumed Monthly Payments) otherwise then due and owing to the MGM Tower
         Noteholders, the Master Servicer, the Special Servicer, the Trustee
         and/or the Fiscal Agent with respect to the MGM Tower Loan Pair; and

                  (xviii) to clear and terminate the MGM Tower Custodial Account
         at the termination of this Agreement pursuant to Section 9.01.

         Any P&I Advance made with respect to the MGM Tower Trust Mortgage Loan
or the MGM Tower REO Trust Mortgage Loan pursuant to Section 4.03 will
constitute part of the "Available Remittance Amount" (within the meaning of the
MGM Tower Co-Lender Agreement) required to be applied with respect to the MGM
Tower Trust Mortgage Loan or any MGM Tower REO Trust Mortgage Loan with respect
thereto pursuant to Section 4.01 of the MGM Tower Co-Lender Agreement on the
subject MGM Tower Master Servicer Remittance Date. Any such P&I Advance shall be
deposited directly into the Collection Account in accordance with Section
4.03(a).

         The Master Servicer shall keep and maintain separate accounting records
in connection with any withdrawal from the MGM Tower Custodial Account pursuant
to clauses (ii) through (xvi) of the second preceding paragraph.

         The Master Servicer shall pay to each of the Special Servicer (or to
third party contractors at the direction of the Special Servicer), the Trustee
and the Fiscal Agent, as applicable, from the MGM Tower Custodial Account,
amounts permitted to be paid thereto from such account promptly upon receipt of
a written statement of a Servicing Officer of the Special Servicer or a
Responsible Officer of the Trustee or the Fiscal Agent, as the case may be,
describing the item and amount to which the Special Servicer (or such third
party contractor), the Trustee or the Fiscal Agent, as the case may be, is
entitled (unless such payment to the Special Servicer, the Trustee or the Fiscal
Agent, as the case may be, is clearly required pursuant to this Agreement, in
which case a written statement is not required). The Master Servicer may rely
conclusively on any such written statement and shall have no duty to
re-calculate the amounts stated therein. The parties seeking payment pursuant to
this section shall each keep and maintain separate accounting for the purpose of
justifying any request for withdrawal from the MGM Tower Custodial Account, on a
loan-by-loan basis.

         To the extent (i) consistent with the MGM Tower Co-Lender Agreement and
(ii) not otherwise included as part of the normal monthly remittances, the
Master Servicer shall transfer from the MGM Tower Custodial Account to the Pool
Custodial Account, promptly upon amounts for such purposes becoming available in
the MGM Tower Custodial Account, the aggregate of all Additional Trust Fund
Expenses and/or any other amounts relating to the MGM Tower Loan Pair that have
been previously paid out of the Pool Custodial Account pursuant to Section
3.05(a) and that, if not previously paid out of the Pool Custodial Account in
accordance with Section 3.05(a), would have been otherwise payable from the MGM
Tower Custodial Account under this Section 3.05B.

         In accordance with Article IV of the MGM Tower Co-Lender Agreement, the
Master Servicer shall, as and when required thereunder, withdraw from the MGM
Tower Custodial Account and (i) transfer to the Pool Custodial Account all
amounts to be remitted to the Trust as holder of the MGM Tower Trust Mortgage
Loan or any MGM Tower REO Trust Mortgage Loan and (ii) remit to the MGM Tower
Non-Trust Mortgage Loan Noteholder the amount due and owing to it. Monthly
remittances to the MGM Tower Non-Trust Mortgage Loan Noteholder shall be made on
the related MGM Tower Master Servicer Remittance Date in accordance with the
reasonable instructions thereof.

         SECTION 3.06. Investment of Funds in the Servicing Accounts, the
                       Reserve Accounts, the Defeasance Deposit Account, the
                       Custodial Account and the REO Accounts.

         (a) The Master Servicer may direct in writing any depository
institution maintaining a Servicing Account, a Reserve Account, the Defeasance
Deposit Account or a Custodial Account (each, for purposes of this Section 3.06,
an "Investment Account"), and the Special Servicer may direct in writing any
depository institution maintaining an REO Account (also, for purposes of this
Section 3.06, an "Investment Account"), to invest, or if it is such depository
institution, may itself invest, the funds held therein (other than, in the case
of the Pool Custodial Account, the Initial Deposit) in one or more Permitted
Investments bearing interest or sold at a discount, and maturing, unless payable
on demand, no later than the Business Day immediately preceding the next
succeeding date on which such funds are required to be withdrawn from such
account pursuant to this Agreement; provided that in the case of any Servicing
Account, any Reserve Account or the Defeasance Deposit Account, such investment
direction shall be subject to the related loan documents and applicable law.
Funds in the Collection Account, the Interest Reserve Account and the Excess
Liquidation Proceeds Account will remain uninvested. All such Permitted
Investments shall be held to maturity, unless payable on demand. Any investment
of funds in an Investment Account shall be made in the name of the Trustee (in
its capacity as such) and, in the case of a Permitted Investment in any
Investment Account solely related to a Loan Combination, the related Non-Trust
Mortgage Loan Noteholder(s). The Master Servicer (with respect to Permitted
Investments of amounts in the Servicing Accounts, the Reserve Accounts, the
Defeasance Deposit Account and the Custodial Accounts) and the Special Servicer
(with respect to Permitted Investments of amounts in the REO Accounts), on
behalf of the Trustee and, in the case of any Investment Account solely related
to a Loan Combination, the related Non-Trust Mortgage Loan Noteholder(s), shall
(and the Trustee hereby designates the Master Servicer and the Special Servicer,
as applicable, as the Person that shall) (i) be the "entitlement holder" of any
Permitted Investment that is a "security entitlement" and (ii) maintain
"control" of any Permitted Investment that is a "certificated security",
"uncertificated security" or "deposit account". For purposes of this Section
3.06(a), (i) the terms "entitlement holder", "security entitlement", "control"
(except with respect to deposit accounts), "certificated security" and
"uncertificated security" shall have the meanings given such terms in Revised
Article 8 (1994 Revision) of the UCC, and the terms "control" (with respect to
deposit accounts) and "deposit account" shall have the meanings given such terms
in Revised Article 9 (1998 Revision) of the UCC, and (ii) "control" of any
Permitted Investment in any Investment Account by the Master Servicer or the
Special Servicer shall constitute "control" by a Person designated by, and
acting on behalf of, the Trustee and, in the case of any Investment Account
solely related to a Loan Combination, the related Non-Trust Mortgage Loan
Noteholder(s), for purposes of Revised Article 8 (1994 Revision) of the UCC or
Revised Article 9 (1998 Revision) of the UCC, as applicable. If amounts on
deposit in an Investment Account are at any time invested in a Permitted
Investment payable on demand, the Master Servicer (in the case of the Custodial
Accounts, the Servicing Accounts, the Reserve Accounts and the Defeasance
Deposit Account) or the Special Servicer (in the case of the REO Accounts)
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 otherwise mature hereunder in an
                  amount equal to at least the lesser of (1) all amounts then
                  payable thereunder and (2) the amount required to be withdrawn
                  on such date; and

                                     -160-
<PAGE>

         (y)      demand payment of all amounts due thereunder promptly upon
                  determination by the Master Servicer or the Special Servicer,
                  as the case may be, that such Permitted Investment would not
                  constitute a Permitted Investment in respect of funds
                  thereafter on deposit in the Investment Account.

         (b) Whether or not the Master Servicer directs the investment of funds
in any of the Servicing Accounts, the Reserve Accounts, the Defeasance Deposit
Account or the Custodial Accounts, interest and investment income realized on
funds deposited therein, to the extent of the Net Investment Earnings, if any,
for each such Investment Account for each Trust Collection Period (or, in the
case of each such Investment Account that solely relates to the GIC Office Loan
Group, for each GIC Office Collection Period) (and, in the case of Servicing
Accounts, Reserve Accounts and the Defeasance Deposit Account, to the extent not
otherwise payable to Mortgagors under applicable law or the related loan
documents), shall be for the sole and exclusive benefit of the Master Servicer
and shall be subject to its withdrawal in accordance with Section 3.03(a),
3.03(d), 3.04(a), 3.04A(a), 3.04B(a), 3.05(a), 3.05A or 3.05B, as applicable.
Whether or not the Special Servicer directs the investment of funds in any of
the REO Accounts, interest and investment income realized on funds deposited
therein, to the extent of the Net Investment Earnings, if any, for such
Investment Account for each Trust Collection Period, in the case of the Pool REO
Account and the MGM Tower REO Account, and for each GIC Office Collection
Period, in the case of the GIC Office REO Account, shall be for the sole and
exclusive benefit of the Special Servicer and shall be subject to its withdrawal
in accordance with Section 3.16(b). If any loss shall be incurred in respect of
any Permitted Investment on deposit in any Investment Account, the Master
Servicer (in the case of (i) the Servicing Accounts, the Reserve Accounts and
the Defeasance Deposit Account (except to the extent that any investment of
funds with respect thereto is at the direction of a Mortgagor in accordance with
the related loan documents or applicable law) and (ii) the Custodial Accounts)
and the Special Servicer (in the case of the REO Accounts) shall promptly
deposit therein from its own funds, without right of reimbursement, no later
than the end of the Trust Collection Period (or, in the case of an Investment
Account that solely relates to the GIC Office Loan Group, the end of the GIC
Office Collection Period) during which such loss was incurred, the amount of the
Net Investment Loss, if any, for such Investment Account for such Collection
Period. Notwithstanding any of the foregoing provisions of this Section 3.06, no
party shall be required under this Agreement to deposit any loss on a deposit of
funds in an Investment Account if such loss is incurred solely as a result of
the insolvency of the federal or state chartered depository institution or trust
company with which such deposit was maintained so long as such depository
institution or trust company satisfied the conditions set forth in the
definition of "Eligible Account" at the time such deposit was made and also as
of a date no earlier than 30 days prior to the insolvency.

         (c) Except as expressly provided otherwise 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 8.02, upon the request of
Certificateholders entitled to a majority of the Voting Rights allocated to a
Class, shall take such action as may be appropriate to enforce such payment or
performance, including the institution and prosecution of appropriate
proceedings.

         (d) Notwithstanding the investment of funds held in any Investment
Account, for purposes of the calculations hereunder, including the calculation
of the Available Distribution Amount, the Master Servicer Remittance Amount, the
GIC Office Available Remittance Amount and the MGM

                                     -161-
<PAGE>

Tower Available Remittance Amount, the amounts so invested shall be deemed to
remain on deposit in such Investment Account.

         (e) Notwithstanding the foregoing, the Initial Deposit shall remain
uninvested.

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

         (a) The Master Servicer shall, consistent with the Servicing Standard,
cause to be maintained for each Mortgaged Property that is not an REO Property,
all insurance coverage as is required under the related Mortgage (except to the
extent that the failure to maintain such insurance coverage is an Acceptable
Insurance Default); provided that, if and to the extent that any such Mortgage
permits the holder thereof any discretion (by way of consent, approval or
otherwise) as to the insurance coverage that the related Mortgagor is required
to maintain, the Master Servicer or Special Servicer, as the case may be, shall
exercise such discretion in a manner consistent with the Servicing Standard; and
provided, further, that, if and to the extent that a Mortgage so permits, the
Master Servicer or Special Servicer, as the case may be, shall use reasonable
best efforts to require the related Mortgagor to obtain the required insurance
coverage from Qualified Insurers that shall have a "claims paying ability" or
"financial strength" rating, as applicable, of at least "A" from S&P and "A3"
from Moody's (if then rated by Moody's, and if not then rated by Moody's, then
an equivalent rating to a rating of "A3" by Moody's by at least one nationally
recognized statistical rating agency besides S&P) (or, in the case of any such
Rating Agency, such lower rating as will not result in an Adverse Rating Event
with respect to any Class of Certificates or any class of GIC Office Pari Passu
Non-Trust Mortgage Loan Securities rated by such Rating Agency, as evidenced in
writing by such Rating Agency); and provided, further, that the Master Servicer
shall cause to be maintained, from Qualified Insurers having a "claims paying
ability" or "financial strength" rating, as applicable, of at least "A" from S&P
and "A3" from Moody's (if then rated by Moody's, and if not then rated by
Moody's, then an equivalent rating to a rating of "A3" by Moody's by at least
one nationally recognized statistical rating agency besides S&P) (or, in the
case of any such Rating Agency, such lower rating as will not result in an
Adverse Rating Event with respect to any Class of Certificates or any class of
GIC Office Pari Passu Non-Trust Mortgage Loan Securities rated by such Rating
Agency, as evidenced in writing by such Rating Agency), for any such Mortgaged
Property any such insurance that the related Mortgagor is required but fails to
maintain, but only to the extent that (i) the Trustee (as mortgagee of record on
behalf of the Certificateholders or, in the case of a Mortgaged Property that
secures a Loan Combination, the Certificateholders and the related Non-Trust
Mortgage Loan Noteholder(s)) has an insurable interest, and (ii) either (A) such
insurance is available at a commercially reasonable rate, or (B) solely in the
case of all-risk insurance or other insurance that covers losses from acts of
terrorism, the failure by the Mortgagor to maintain such insurance coverage has
not been determined by the Special Servicer to constitute an Acceptable
Insurance Default. The GIC Office Controlling Party, in the case of the GIC
Office Mortgaged Property, the MGM Tower Controlling Party, in the case of the
MGM Tower Mortgaged Property, and the Controlling Class Representative, in the
case of any other Mortgaged Property, may request that earthquake insurance be
secured for a Mortgaged Property by the related Mortgagor, to the extent such
insurance may reasonably be obtained and provided the related loan documents and
applicable law give the mortgagee the right to request such insurance coverage
and such loan documents require the Mortgagor to obtain earthquake insurance at
the request of the mortgagee. Subject to Section 3.17(a), the Special Servicer,
in accordance with the Servicing Standard, shall also cause to be maintained for
each REO Property no less insurance coverage than was previously required of the
Mortgagor under the

                                     -162-
<PAGE>

related Mortgage; provided that such insurance is available at commercially
reasonable rates and the subject hazards are at the time commonly insured
against for properties similar to the subject REO Property located in or around
the region in which such REO Property is located (or, in the case of all-risk
insurance or other insurance that covers acts of terrorism, either such
insurance is available at a commercially reasonable rate or the subject hazards
are at the time commonly insured against for properties similar to the subject
REO Property located in or around the region in which such REO Property is
located); and provided, further, that all such insurance shall be obtained from
Qualified Insurers that shall have a "claims paying ability" or "financial
strength" rating, as applicable, of at least "A" from S&P and "A2" from Moody's
(or, in the case of either Rating Agency, such lower rating as will not result
in an Adverse Rating Event with respect to any Class of Certificates or any
class of GIC Office Pari Passu Non-Trust Mortgage Loan Securities rated by such
Rating Agency, as evidenced in writing by such Rating Agency). All such
insurance policies shall contain (if they insure against loss to property and do
not relate to an REO Property) a "standard" mortgagee clause, with loss payable
to the Master Servicer (in the case of insurance maintained in respect of
Mortgage Loans, including Specially Serviced Mortgage Loans), and shall be in
the name of the Special Servicer (in the case of insurance maintained in respect
of REO Properties), on behalf of the Trustee.

         Any amounts collected by the Master Servicer or the Special Servicer
under any such policies (other than amounts to be applied to the restoration or
repair of the related Mortgaged Property or REO Property or amounts to be
released to the related Mortgagor, in each case subject to the rights of any
tenants and ground lessors, as the case may be, and in each case in accordance
with the terms of the related Mortgage and the Servicing Standard) shall be
deposited in the applicable Custodial Account in accordance with Section
3.04(a), 3.04A(a) or 3.04B(a), as applicable, in the case of amounts received in
respect of a Mortgage Loan, or in the applicable REO Account in accordance with
Section 3.16(b), in the case of amounts received in respect of an REO Property.
Any cost incurred by the Master Servicer or the Special Servicer in maintaining
any such insurance (including any earthquake insurance maintained at the request
of the GIC Office Controlling Party, the MGM Tower Controlling Party or the
Controlling Class Representative, as applicable) shall not, for purposes hereof,
including calculating monthly distributions to Certificateholders, be added to
the unpaid principal balance or Stated Principal Balance of the related Mortgage
Loan(s) or REO Mortgage Loan(s), notwithstanding that the terms of such loan so
permit, but shall be recoverable by the Master Servicer or the Special Servicer,
as applicable, as a Servicing Advance.

         (b) If either the Master Servicer or the Special Servicer shall obtain
and maintain, or cause to be obtained and maintained, a blanket policy insuring
against hazard losses on all of the Mortgage Loans and/or REO Properties that it
is required to service and administer, then, to the extent such policy (i) is
obtained from a Qualified Insurer having (or whose obligations are guaranteed or
backed, in writing, by an entity having) a "claims paying ability" or "financial
strength" rating, as applicable, of at least "A" from S&P and "A3" from Moody's
(if then rated by Moody's, and if not then rated by Moody's, then a rating of
"A:IX" or better by A.M. Best's Key Rating Guide or an equivalent rating to a
rating of "A3" from Moody's by at least one nationally recognized statistical
rating agency besides S&P) (or, in the case of either Rating Agency, such lower
rating as will not result in an Adverse Rating Event with respect to any Class
of Certificates or any class of GIC Office Pari Passu Non-Trust Mortgage Loan
Securities rated by such Rating Agency, as evidenced in writing by such Rating
Agency), and (ii) provides protection equivalent to the individual policies
otherwise required, then the Master Servicer or the Special Servicer, as the
case may be, shall conclusively be deemed to have satisfied its obligation to
cause hazard insurance to be maintained on the related Mortgaged Properties

                                     -163-
<PAGE>

and/or subject REO Properties. Such blanket policy may contain a deductible
clause (not in excess of a customary amount), in which case the Master Servicer
or the Special Servicer, as appropriate, shall, if there shall not have been
maintained on the related Mortgaged Property or subject REO Property an
individual hazard insurance policy complying with the requirements of Section
3.07(a), and there shall have been one or more losses that would have been
covered by such individual policy, promptly deposit into the applicable
Custodial Account from its own funds the amount not otherwise payable under the
blanket policy because of the deductible clause therein, to the extent that any
such deductible exceeds the deductible limitation that pertained to the related
Mortgage Loan (or in the absence of any such deductible limitation, the
deductible limitation for an individual policy which is consistent with the
Servicing Standard). The Master Servicer or the Special Servicer, as
appropriate, shall prepare and present, on behalf of itself, the Trustee, the
Certificateholders and, in the case of a Mortgaged Property that secures a Loan
Combination, the related Non-Trust Mortgage Loan Noteholder(s), claims under any
such blanket policy in a timely fashion in accordance with the terms of such
policy.

         (c) Subject to the third paragraph of this Section 3.07(c), each of the
Master Servicer and the Special Servicer shall at all times during the term of
this Agreement (or, in the case of the Special Servicer, at all times during the
term of this Agreement in which Specially Serviced Mortgage Loans and/or REO
Properties are part of the Trust Fund) keep in force with Qualified Insurers
having (or whose obligations are guaranteed or backed, in writing, by entities
having) a "claims paying ability" or "financial strength" rating, as applicable,
of at least "A" from S&P and "Baa3" from Moody's (or, if not then rated by
Moody's, then at least "A:IX" by A.M. Best's Key Rating Guide) (or, in the case
of either Rating Agency, such lower rating as will not result in an Adverse
Rating Event with respect to any Class of Certificates or any class of GIC
Office Pari Passu Non-Trust Mortgage Loan Securities rated by such Rating
Agency, as evidenced in writing by such Rating Agency), a fidelity bond, which
fidelity bond shall be in such form and amount as would permit it to be a
qualified Fannie Mae seller-servicer of multifamily mortgage loans, or in such
other form and amount as would not cause an Adverse Rating Event with respect to
any Class of Certificates or any class of GIC Office Pari Passu Non-Trust
Mortgage Loan Securities rated by either Rating Agency (as evidenced in writing
from each Rating Agency). Each of the Master Servicer and the Special Servicer
shall be deemed to have complied with the foregoing provision if an Affiliate
thereof has such fidelity bond coverage and, by the terms of such fidelity bond,
the coverage afforded thereunder extends to the Master Servicer or the Special
Servicer, as the case may be.

         Subject to the third paragraph of this Section 3.07(c), each of the
Master Servicer and the Special Servicer shall at all times during the term of
this Agreement (or, in the case of the Special Servicer, at all times during the
term of this Agreement in which Specially Serviced Mortgage Loans and/or REO
Properties are part of the Trust Fund) also keep in force with Qualified
Insurers having (or whose obligations are guaranteed or backed, in writing, by
entities having) a "claims paying ability" or "financial strength" rating, as
applicable, of at least "A" from S&P and "Baa3" from Moody's (or, if not rated
by Moody's, then at least "A:IX" by A.M. Best's Key Rating Guide) (or, in the
case of either Rating Agency, such lower rating as will not result in an Adverse
Rating Event with respect to any Class of Certificates or any class of GIC
Office Pari Passu Non-Trust Mortgage Loan Securities rated by such Rating
Agency, as evidenced in writing by such Rating Agency), a policy or policies of
insurance covering loss occasioned by the errors and omissions of its officers,
employees and agents in connection with its servicing obligations hereunder,
which policy or policies shall be in such form and amount as would permit it to
be a qualified Fannie Mae seller-servicer of multifamily mortgage loans, or in
such other form and amount as would not cause an Adverse Rating Event with
respect to any Class of

                                     -164-
<PAGE>

Certificates or any class of GIC Office Pari Passu Non-Trust Mortgage Loan
Securities rated by either Rating Agency (as evidenced in writing from each
Rating Agency). Each of the Master Servicer and the Special Servicer shall be
deemed to have complied with the foregoing provisions if an Affiliate thereof
has such insurance and, by the terms of such policy or policies, the coverage
afforded thereunder extends to the Master Servicer or the Special Servicer, as
the case may be.

         Notwithstanding the foregoing, for so long as the long-term debt
obligations of the Master Servicer or Special Servicer, as the case may be, are
rated at least "A2" from Moody's (if then rated by Moody's, and if not then
rated by Moody's, then an equivalent rating by at least one additional
nationally recognized statistical rating agency besides S&P) and "A" from S&P
(or, in the case of either Rating Agency, such lower rating as will not result
in an Adverse Rating Event with respect to any Class of Certificates or any
class of GIC Office Pari Passu Non-Trust Mortgage Loan Securities rated by such
Rating Agency, as evidenced in writing by such Rating Agency), such Person may
self-insure with respect to the risks described in this Section 3.07(c).

         (d) In the event that either of the Master Servicer or the Special
Servicer has actual knowledge of any event (an "Insured Environmental Event")
giving rise to a claim under any Environmental Insurance Policy in respect of
any Environmentally Insured Mortgage Loan for which the Mortgagor has not filed
a claim or in respect of an REO Property, the Master Servicer shall notify the
Special Servicer if such Mortgage Loan is a Specially Serviced Mortgage Loan,
and the Special Servicer shall notify the Master Servicer in all cases. Upon
becoming aware of such Insured Environmental Event, the Master Servicer, in the
case of a Performing Mortgage Loan, and the Special Servicer, in the case of a
Specially Serviced Mortgage Loan or an REO Property, in accordance with the
terms of such Environmental Insurance Policy and the Servicing Standard, shall
timely make a claim thereunder with the appropriate insurer and shall take such
other actions necessary under such Environmental Insurance Policy in order to
realize the full value thereof for the benefit of the Certificateholders. With
respect to each Environmental Insurance Policy in respect of an Environmentally
Insured Mortgage Loan, the Master Servicer (in the case of any such Mortgage
Loan that is a Performing Mortgage Loan) and the Special Servicer (in the case
of any such Mortgage Loan that is a Specially Serviced Mortgage Loan or in the
case of an REO Property) shall each review and familiarize itself with the terms
and conditions relating to enforcement of claims and shall, in the event the
Master Servicer or the Special Servicer has actual knowledge of an Insured
Environmental Event giving rise to a claim under such policy, monitor the dates
by which any claim must be made or any action must be taken under such policy to
realize the full value thereof for the benefit of the Certificateholders.

         The Master Servicer (in the case of Performing Mortgage Loans) and the
Special Servicer (in the case of Specially Serviced Mortgage Loans and REO
Properties) shall each abide by the terms and conditions precedent to payment of
claims under the Environmental Insurance Policies with respect to the
Environmentally Insured Mortgage Loans and take all such actions as may be
required to comply with the terms and provisions of such policies in order to
maintain such policies in full force and effect and to make claims thereunder.

         In the event that either the Master Servicer or the Special Servicer
receives notice of a termination of any Environmental Insurance Policy with
respect to an Environmentally Insured Mortgage Loan, then the party receiving
such notice shall, within five (5) Business Days after receipt thereof, provide
written notice of such termination to the other such party and the Trustee. Upon
receipt

                                     -165-
<PAGE>

of such notice, the Master Servicer, with respect to a Performing Mortgage Loan,
or the Special Servicer, with respect to a Specially Serviced Mortgage Loan or
an REO Property, shall address such termination in accordance with Section
3.07(a). Any legal fees, premiums or other out-of-pocket costs incurred in
accordance with the Servicing Standard in connection with enforcing the
obligations of the Mortgagor under any Environmental Insurance Policy or a
resolution of such termination of an Environmental Insurance Policy shall be
paid by the Master Servicer and shall be reimbursable to it as a Servicing
Advance.

         The Master Servicer (with respect to Performing Mortgage Loans) and the
Special Servicer (with respect to Specially Serviced Mortgage Loans) shall
monitor the actions, and enforce the obligations, of the related Mortgagor under
each Environmentally Insured Mortgage Loan insofar as such actions/obligations
relate to (i) to the extent consistent with Section 3.07(a), the maintenance
(including, without limitation, any required renewal) of an Environmental
Insurance Policy with respect to the related Mortgaged Property or (ii)
environmental testing or remediation at the related Mortgaged Property.

         SECTION 3.08. Enforcement of Alienation Clauses.

         (a) If, with respect to any Performing Mortgage Loan, the Master
Servicer receives a request from a Mortgagor regarding the transfer of the
related Mortgaged Property to, and assumption of such Mortgage Loan by, another
Person or transfers of certain interests in such Mortgagor, then the Master
Servicer shall promptly obtain relevant information for purposes of evaluating
such request. If the Master Servicer determines, consistent with the Servicing
Standard, to approve such transfer and/or assumption, then the Master Servicer
shall promptly provide to the Special Servicer a copy of such recommendation
(which shall include the reason therefor) and the materials upon which such
recommendation is based. The Special Servicer shall have the right hereunder,
within 15 days of receipt of such recommendation and supporting materials and
any other materials reasonably requested by the Special Servicer, to reasonably
withhold or grant consent to any such request for such transfer and/or
assumption in accordance with the terms of the subject Mortgage Loan and this
Agreement, including, without limitation, the Servicing Standard; provided that
any grant of consent on the part of the Special Servicer shall be subject to
Section 3.08(d), Section 6.11, Section 6.12 and/or Section 6.13, in each case if
and as applicable. If the Special Servicer does not respond within such 15-day
period, the Special Servicer's consent shall be deemed granted. If the Special
Servicer consents or is deemed to have consented to such proposed transfer
and/or assumption, the Master Servicer shall process such request of the related
Mortgagor; and, in the case of a transfer of the related Mortgaged Property to,
and assumption of such Mortgage Loan by, another Person, the Master Servicer
(subject to Section 3.08(d)) shall be authorized to enter into an assumption or
substitution agreement with the Person, which shall be a Single Purpose Entity,
to whom the related Mortgaged Property has been or is proposed to be conveyed
and/or release the original Mortgagor from liability under such Mortgage Loan
and substitute as obligor thereunder the Person to whom the related Mortgaged
Property has been or is proposed to be conveyed; provided, however, that the
Master Servicer shall not enter into any such agreement to the extent that any
terms thereof would result in an Adverse REMIC Event or Adverse Grantor Trust
Event or create any lien on a Mortgaged Property that is senior to, or on parity
with, the lien of the related Mortgage. The Master Servicer shall notify the
Trustee, the Special Servicer, each Rating Agency, the Controlling Class
Representative and, in the case of a Loan Combination, the related Non-Trust
Mortgage Loan Noteholder(s), of any assumption or substitution agreement
executed pursuant to this Section 3.08(a) and shall forward thereto a copy of
such agreement together with a Review Package.

                                     -166-
<PAGE>

Subject to the terms of the related loan documents, no assumption of a
Cross-Collateralized Mortgage Loan shall be made without the assumption of all
other Trust Mortgage Loans making up the related Cross-Collateralized Group.
Further, subject to the terms of the related loan documents and applicable law,
no assumption of a Mortgage Loan shall be made or transfer of interest in a
Mortgagor approved, unless all costs in connection therewith, including any
arising from seeking Rating Agency confirmation, are paid by the related
Mortgagor.

         If any Performing Mortgage Loan contains express restrictions on
transfers of the related Mortgaged Property and/or transfers of interests in the
related Mortgagor, and if any such proposed transfer has not been approved
pursuant to the preceding paragraph, then the Master Servicer, on behalf of the
Trustee (as mortgagee of record on behalf of the Certificateholders and, in the
case a Mortgaged Property that secures a Loan Combination, the related Non-Trust
Mortgage Loan Noteholder(s)), shall, to the extent permitted by applicable law,
enforce such restrictions, unless the Master Servicer has determined, in its
reasonable, good faith judgment, that enforcement of such restrictions would be
a violation of the Servicing Standard (as evidenced by an Officer's Certificate
setting forth the basis for such determination delivered, together with a Review
Package in respect thereof, to the Trustee, each Rating Agency, the Controlling
Class Representative and, with respect to a Loan Combination, the related
Non-Trust Mortgage Loan Noteholder(s)); provided that any such waiver of such
restrictions shall be subject to Section 3.08(d), Section 6.11, Section 6.12
and/or Section 6.13, in each case if and as applicable.

         (b) If, with respect to a Specially Serviced Mortgage Loan, the Master
Servicer receives a request from a Mortgagor for consent to a transfer of the
related Mortgaged Property and assumption of such Specially Serviced Mortgage
Loan and/or consent to a transfer of interests in the related Mortgagor, the
Master Servicer shall immediately notify the Special Servicer of such request
and deliver to the Special Servicer any documents that the Master Servicer shall
have received regarding the proposed transfer and assumption. Subject to Section
3.08(d), Section 6.11, Section 6.12 and/or Section 6.13, in each case if and as
applicable, the Special Servicer shall determine whether to grant such consent
or to enforce any restrictions on such transfer and/or assumption contained in
the related loan documents, in accordance with the Servicing Standard.

         Upon consent by the Special Servicer to any proposed transfer of a
Mortgaged Property and assumption by the proposed transferee of the related
Mortgage Loan pursuant to this Section 3.08(b), the Special Servicer shall
process the request of the related Mortgagor for such transfer and assumption
and shall be authorized to enter into an assumption or substitution agreement
with the Person, which shall be a Single Purpose Entity, to whom the related
Mortgaged Property has been or is proposed to be conveyed and/or release the
original Mortgagor from liability under the related Mortgage Loan and substitute
as obligor thereunder the Person to whom the related Mortgaged Property has been
or is proposed to be conveyed; provided, however, that the Special Servicer
shall not enter into any such agreement to the extent that any terms thereof
would result in an Adverse REMIC Event or Adverse Grantor Trust Event or create
any lien on a Mortgaged Property that is senior to, or on parity with, the lien
of the related Mortgage. The Special Servicer shall notify the Trustee, the
Master Servicer, each Rating Agency, the Controlling Class Representative and,
with respect to a Loan Combination, the related Non-Trust Mortgage Loan
Noteholder(s), of any assumption or substitution agreement executed pursuant to
this Section 3.08(b) and shall forward thereto a copy of such agreement. Subject
to the terms of the related loan documents, no assumption of a
Cross-Collateralized Mortgage Loan shall be made without the assumption of all
other Trust Mortgage Loans making up the related Cross-

                                     -167-
<PAGE>

Collateralized Group. Further, subject to the terms of the related loan
documents and applicable law, no assumption of a Mortgage Loan shall be made
unless all costs in connection therewith, including any arising from seeking
Rating Agency confirmation, are paid by the related Mortgagor.

         (c) If, with respect to a Performing Mortgage Loan, the Master Servicer
receives a request from the related Mortgagor regarding a further encumbrance of
the related Mortgaged Property or of an interest in the related Mortgagor, then
the Master Servicer shall promptly obtain relevant information for purposes of
evaluating such request. If the Master Servicer determines, consistent with the
Servicing Standard, to approve such further encumbrance, then the Master
Servicer shall provide to the Special Servicer a written copy of such
recommendation (which shall include the reason therefor) and the materials upon
which such recommendation is based. The Special Servicer shall have the right
hereunder, within 15 days of receipt of such recommendation and supporting
materials and any other materials reasonably requested by the Special Servicer,
to reasonably withhold or, subject to Section 3.08(d) and, further, subject to
the Special Servicer obtaining any consent to the extent required pursuant to
Section 6.11, Section 6.12 and/or Section 6.13, in each case if and as
applicable, grant consent to any such request for such further encumbrance of
the related Mortgaged Property or of an interest in the related Mortgagor, as
applicable, in accordance with the terms of such Mortgage Loan and this
Agreement and subject to the Servicing Standard. If the Special Servicer does
not respond within such 15-day period, such party's consent shall be deemed
granted. If the Special Servicer consents or is deemed to have consented to such
further encumbrance of the related Mortgaged Property or of an interest in the
related Mortgagor, as applicable, the Master Servicer shall process such request
of the related Mortgagor. If the Special Servicer does not consent to, and is
not deemed to have consented to, such further encumbrance, then the Master
Servicer, on behalf of the Trustee (as mortgagee of record on behalf of the
Certificateholders and, with respect to a Loan Combination, the related
Non-Trust Mortgage Loan Noteholder(s)) shall, to the extent permitted by
applicable law, enforce the restrictions contained in the related loan documents
on further encumbrances of the related Mortgaged Property and/or of an interest
in the related Mortgagor, as applicable, unless the Master Servicer has
determined, in its reasonable, good faith judgment, that failure to waive such
restrictions would be a violation of the Servicing Standard (as evidenced by an
Officer's Certificate setting forth the basis for such determination delivered
to the Trustee and the Special Servicer, each Rating Agency and, with respect to
a Loan Combination, the related Non-Trust Mortgage Loan Noteholder(s)); provided
that any such waiver of such restrictions shall be subject to Section 3.08(d)
and Section 6.11, Section 6.12 and/or Section 6.13, in each case if and as
applicable. To the extent permitted by the applicable loan documents and
applicable law, the Master Servicer may charge the related Mortgagor (and retain
to the extent permitted under Section 3.11) a fee in connection with any
enforcement or waiver contemplated in this paragraph of subsection (c).

         With respect to any Specially Serviced Mortgage Loan, the Special
Servicer, on behalf of the Trustee (as mortgagee of record on behalf of the
Certificateholders and, in the case of a Mortgaged Property that secures a Loan
Combination, the related Non-Trust Mortgage Loan Noteholder(s)) shall, to the
extent permitted by applicable law, enforce the restrictions contained in the
related loan documents on further encumbrances of the related Mortgaged Property
and/or of interests in the related Mortgagor, as applicable, and shall process
all documentation in connection therewith, unless the Special Servicer has
determined, in its reasonable, good faith judgment, that waiver of such
restrictions would be in accordance with the Servicing Standard (as evidenced by
an Officer's Certificate setting forth the basis for such determination
delivered to the Trustee, the Master Servicer, each Rating Agency and, with
respect to a Loan Combination, the related Non-Trust Mortgage Loan
Noteholder(s)); provided that any

                                     -168-
<PAGE>

such waiver of such restrictions shall be subject to Section 3.08(d) and Section
6.11, Section 6.12 and/or Section 6.13, in each case if and as applicable. To
the extent permitted by the applicable loan documents and applicable law, the
Special Servicer may charge the related Mortgagor (and retain to the extent
permitted under Section 3.11) a fee in connection with any enforcement or waiver
contemplated in this paragraph of subsection (c).

         (d) Notwithstanding anything to the contrary contained in this Section
3.08, but subject to the related loan documents and applicable law, (A) (i) if
the then unpaid principal balance of the subject Trust Mortgage Loan is at least
equal to $20,000,000, then neither the Master Servicer nor the Special Servicer
shall waive any restrictions contained in the related Mortgage on transfers of
the related Mortgaged Property or on transfers of interests in the related
Mortgagor, and (ii) if (w) the then unpaid principal balance of the subject
Trust Mortgage Loan is at least equal to 2% of the then aggregate principal
balance of the Mortgage Pool or (x) the subject Trust Mortgage Loan is then one
of the ten largest Trust Mortgage Loans in the Mortgage Pool or (y) the
aggregate loan-to-value ratio of the subject Trust Mortgage Loan (together with
any additional loans that would further encumber the related Mortgaged Property
and/or interests in the related Mortgagor) would be equal to or greater than 85%
or (z) the aggregate debt service coverage ratio of the related Mortgaged
Property (taking into account any additional loans that would further encumber
the related Mortgaged Property and/or interests in the related Mortgagor) would
be less than 1.20x, then the Special Servicer shall not waive any restrictions
contained in the related Mortgage on further encumbrances of the related
Mortgaged Property or of interests in the related Mortgagor, unless, in the case
of either (i) or (ii) above, the Special Servicer or the Master Servicer, as the
case may be, shall have received prior written confirmation from S&P that such
action would not result in an Adverse Rating Event with respect to any Class of
Certificates or, if the GIC Office Loan Group is involved, any class of GIC
Office Pari Passu Non-Trust Mortgage Loan Securities rated by such Rating
Agency, and (B) if the subject Trust Mortgage Loan is then one of the ten
largest Trust Mortgage Loans in the Mortgage Pool, then neither the Master
Servicer nor the Special Servicer, as applicable, shall waive any restrictions
contained in the related Mortgage on transfers or further encumbrances of the
related Mortgaged Property or on transfers of interests in the related
Mortgagor, unless the Master Servicer or the Special Servicer, as the case may
be, shall have received prior written confirmation from Moody's that such action
would not result in an Adverse Rating Event with respect to any Class of
Certificates or, if the GIC Office Loan Group is involved, any class of GIC
Office Pari Passu Non-Trust Mortgage Loan Securities rated by such Rating
Agency. In connection with any request for rating confirmation from a Rating
Agency pursuant to this Section 3.08(d), the Master Servicer or the Special
Servicer, as the case may be, shall deliver a Review Package to such Rating
Agency. Further, subject to the terms of the related loan documents and
applicable law, no waiver of a restriction contained in the related Mortgage on
transfers of the related Mortgaged Property or interests in the related
Mortgagor or on further encumbrances thereof may be waived by the Master
Servicer or the Special Servicer, as applicable, unless all costs in connection
therewith, including any arising from seeking Rating Agency confirmation, are
paid by the related Mortgagor. To the extent not collected from the related
Mortgagor (or from the Depositor or the UBS Mortgage Loan Seller pursuant to
Section 2.03(e)), any rating agency charges in connection with the foregoing
shall be paid by the Master Servicer as a Servicing Advance.

         SECTION 3.09. Realization Upon Defaulted Mortgage Loans; Required
                       Appraisals; Appraisal Reduction Calculation.

         (a) The Special Servicer shall, subject to Sections 3.09(b), 3.09(c),
3.09(d), 6.11, 6.12 and 6.13, exercise reasonable efforts, consistent with the
Servicing Standard, to foreclose upon or otherwise comparably convert the
ownership of properties securing such of the Specially Serviced Mortgage Loans
as come into and continue in default and as to which no satisfactory
arrangements can be made for collection of delinquent payments, including
pursuant to Section 3.20; provided that neither the Master Servicer nor the
Special Servicer shall, with respect to any ARD Mortgage Loan after its
Anticipated Repayment Date, take any enforcement action with respect to the
payment of Additional Interest (other than the making of requests for its
collection) unless (i) the taking of an enforcement action with respect to the
payment of other amounts due under such ARD Mortgage Loan is, in the good faith
and reasonable judgment of the Special Servicer, necessary, appropriate and
consistent with the Servicing Standard or (ii) all other amounts due under such
ARD Mortgage Loan have been paid, the payment of such Additional Interest has
not been forgiven in accordance with Section 3.20 and, in the good faith and
reasonable judgment of the Special Servicer, the Liquidation Proceeds expected
to be recovered in connection with such enforcement action will cover the
anticipated costs of such enforcement action and, if applicable, any associated
interest accrued on Advances. Subject to Section 3.11(h), the Special Servicer
shall request that the Master Servicer advance all costs and expenses incurred
by it in any such proceedings, and the Master Servicer shall be entitled to
reimbursement therefor as provided in Section 3.05(a), Section 3.05A or Section
3.05B, as applicable. The Special Servicer shall be responsible, consistent with
the Servicing Standard, for determining whether to exercise any rights it may
have under the cross-collateralization and/or cross-default provisions of a
Cross-Collateralized Mortgage Loan. Nothing contained in this Section 3.09 shall
be construed so as to require the Special Servicer, on behalf of the
Certificateholders and, in the case of a Mortgaged Property that secures a Loan
Combination, on behalf of the affected Non-Trust Mortgage Loan Noteholder(s), to
make a bid on any Mortgaged Property at a foreclosure sale or similar proceeding
that is in excess of the fair market value of such property, as determined by
the Special Servicer in its reasonable and good faith judgment taking into
account the factors described in Section 3.18 and the results of any appraisal
obtained as provided below in this Section 3.09, all such bids to be made in a
manner consistent with the Servicing Standard.

         If and when the Master Servicer or the Special Servicer deems it
necessary and prudent for purposes of establishing the fair market value of any
Mortgaged Property securing a Specially Serviced Mortgage Loan, whether for
purposes of bidding at foreclosure or otherwise, it may have an appraisal
performed with respect to such property by an Independent Appraiser or other
expert in real estate matters, which appraisal shall take into account the
factors specified in Section 3.18, and the cost of which appraisal shall be
covered by, and be reimbursable as, a Servicing Advance; provided that if the
Master Servicer intends to obtain an appraisal in connection with the foregoing,
the Master Servicer shall so notify the Special Servicer and consult with the
Special Servicer regarding such appraisal.

         If any Mortgage Loan or Loan Combination becomes a Required Appraisal
Loan, then the Special Servicer shall (i) obtain or conduct, as applicable, a
Required Appraisal within 60 days of such occurrence (unless a Required
Appraisal was obtained or conducted, as applicable, with respect to such
Required Appraisal Loan within the prior 12 months and the Special Servicer
reasonably believes, in accordance with the Servicing Standard, that no material
change has subsequently occurred with respect to the related Mortgaged Property
that would draw into question the applicability of such

                                     -170-
<PAGE>

Required Appraisal) and (ii) obtain or conduct, as applicable, an update of the
most recent Required Appraisal approximately 12 months following the most recent
Required Appraisal or subsequent update thereof for so long as such Mortgage
Loan (or any successor REO Mortgage Loan with respect thereto) or such Loan
Combination, as the case may be, remains a Required Appraisal Loan. The Special
Servicer shall deliver copies of all such Required Appraisals and updated
Required Appraisals to the Trustee, the Master Servicer and, in the case of a
Mortgaged Property that secures a Loan Combination, the related Non-Trust
Mortgage Loan Noteholder(s), in each such case, promptly following the Special
Servicer's receipt of the subject appraisal, and, upon request, to the
Controlling Class Representative. Based on each such Required Appraisal and
updated Required Appraisal, the Special Servicer shall (monthly, on each
Determination Date, until the subject Required Appraisal Loan ceases to be such)
calculate and notify the Trustee, the Master Servicer, the Controlling Class
Representative, and, in the case of any Mortgaged Property that secures a Loan
Combination, the related Non-Trust Mortgage Loan Noteholder(s), of any resulting
Appraisal Reduction Amount in respect of the subject Required Appraisal Loan.
Such calculations by the Special Servicer shall be subject to review and
confirmation by the Master Servicer, provided that the Master Servicer may rely
on any information provided by the Special Servicer. The Master Servicer shall,
at the direction of the Special Servicer, advance the cost of each such Required
Appraisal and updated Required Appraisal; provided, however, that such expense
will be subject to reimbursement to the Master Servicer as a Servicing Advance
out of the related Custodial Account pursuant to Section 3.05(a), Section 3.05A
or Section 3.05B, as applicable. At any time that an Appraisal Reduction Amount
exists with respect to any Required Appraisal Loan, the GIC Office Controlling
Party (in the case of the GIC Office Loan Group), the MGM Tower Controlling
Party (in the case of the MGM Tower Loan Pair) or the Controlling Class
Representative (in all other cases), as applicable, may, at its own expense,
obtain and deliver to the Master Servicer, the Special Servicer and the Trustee
an appraisal that is reasonably satisfactory to the Special Servicer and
satisfies the requirements of a "Required Appraisal", and upon the written
request of the GIC Office Controlling Party, the MGM Tower Controlling Party or
the Controlling Class Representative, as applicable, the Special Servicer shall
recalculate the Appraisal Reduction Amount in respect of such Required Appraisal
Loan based on such appraisal delivered by such party and shall notify the
Trustee, the Master Servicer, the GIC Office Controlling Party (in the case of
the GIC Office Loan Group), the MGM Tower Controlling Party (in the case of the
MGM Tower Loan Pair) and the Controlling Class Representative of such
recalculated Appraisal Reduction Amount.

         (b) Notwithstanding any other provision of this Agreement, no Mortgaged
Property shall be acquired by the Special Servicer on behalf of the
Certificateholders (and, in the case of a Mortgaged Property that secures a Loan
Combination, the related Non-Trust Mortgage Loan Noteholder(s)) under such
circumstances, in such manner or pursuant to such terms as would, in the
reasonable, good faith judgment of the Special Servicer (exercised in accordance
with the Servicing Standard), (i) cause such Mortgaged Property to fail to
qualify as "foreclosure property" within the meaning of Section 860G(a)(8) of
the Code (unless the portion of such Mortgaged Property that is not treated as
"foreclosure property" and that is held by REMIC I at any given time constitutes
not more than a de minimis amount of the assets of REMIC I, within the meaning
of Treasury regulations section 1.860D-1(b)(3)(i) and (ii)), or (ii) except as
permitted by Section 3.17(a), subject the Trust Fund to the imposition of any
federal income taxes under the Code. Subject to the foregoing, however, a
Mortgaged Property may be acquired through a single member limited liability
company if the Special Servicer determines that such an action is appropriate to
protect the Trust (and, in the case of a Mortgaged Property that secures a Loan

         In addition, the Special Servicer shall not acquire any personal
property pursuant to this Section 3.09 unless either:

                  (i) such personal property is, in the reasonable, good faith
         judgment of the Special Servicer (exercised in accordance with the
         Servicing Standard), incident to real property (within the meaning of
         Section 856(e)(1) of the Code) so acquired by the Special Servicer; or

                  (ii) the Special Servicer shall have obtained an Opinion of
         Counsel (the cost of which shall be covered by, and be reimbursable as,
         a Servicing Advance) to the effect that the holding of such personal
         property as part of the Trust Fund will not cause the imposition of a
         tax on any REMIC Pool under the REMIC Provisions or cause any REMIC
         Pool to fail to qualify as a REMIC at any time that any Certificate is
         outstanding.

         (c) Notwithstanding the foregoing provisions of this Section 3.09,
neither the Master Servicer nor the Special Servicer shall, on behalf of the
Trustee (and, in the case of the GIC Office Mortgaged Property or the MGM Tower
Mortgaged Property, on behalf of the related Non-Trust Mortgage Loan
Noteholder(s)), obtain title to a Mortgaged Property by foreclosure, deed in
lieu of foreclosure or otherwise, or take any other action with respect to any
Mortgaged Property, if, as a result of any such action, the Trustee, on behalf
of the Certificateholders (and, in the case of the GIC Office Mortgaged Property
or the MGM Tower Mortgaged Property, on behalf of the related Non-Trust Mortgage
Loan Noteholder(s)), could, in the reasonable, good faith judgment of the
Special Servicer, exercised in accordance with the Servicing Standard, be
considered to hold title to, to be a "mortgagee-in-possession" of, or to be an
"owner" or "operator" of such Mortgaged Property within the meaning of CERCLA or
any comparable law (a "potentially responsible party"), unless such action is
consistent with Section 6.11, Section 6.12, and/or Section 6.13, in each case if
and as applicable, and the Special Servicer has previously determined (as
evidenced by an Officer's Certificate to such effect delivered to the Trustee
(and, in the case of the GIC Office Mortgaged Property or the MGM Tower
Mortgaged Property, to the related Non-Trust Mortgage Loan Noteholder(s)) that
shall specify all of the bases for such determination), in accordance with the
Servicing Standard and based on an Environmental Assessment of such Mortgaged
Property performed by an Independent Person, who regularly conducts
Environmental Assessments, within six months prior to any such acquisition of
title or other action (a copy of which Environmental Assessment shall be
delivered to the Trustee, the Master Servicer and, in the case of the GIC Office
Mortgaged Property or the MGM Tower Mortgaged Property, the related Non-Trust
Mortgage Loan Noteholder(s)), that:

                  (i) the Mortgaged Property is in compliance with applicable
         environmental laws and regulations or, if not, that it would (taking
         into account the coverage provided under any related Environmental
         Insurance Policy) maximize the recovery on the related Mortgage Loan to
         the Certificateholders (or, if a Loan Combination is involved, to the
         Certificateholders and the related Non-Trust Mortgage Loan
         Noteholder(s)), as a collective whole, on a present value basis (the
         relevant discounting of anticipated collections that will be
         distributable to Certificateholders (or, if a Loan Combination is
         involved, to the Certificateholders and the related Non-Trust Mortgage
         Loan Noteholder(s)), as a collective whole, to be performed at the
         related Mortgage Rate(s)) to acquire title to or possession of the
         Mortgaged Property and to take such actions as are necessary to bring
         the Mortgaged Property into compliance therewith in all material
         respects; and

                                     -172-

                  (ii) there are no circumstances or conditions present at the
         Mortgaged Property relating to the use, management or disposal of
         Hazardous Materials for which investigation, testing, monitoring,
         containment, clean-up or remediation could be required under any
         applicable environmental laws and regulations or, if such circumstances
         or conditions are present for which any such action could reasonably be
         expected to be required, that it would (taking into account the
         coverage provided under any related Environmental Insurance Policy)
         maximize the recovery on the related Mortgage Loan to the
         Certificateholders (or, if a Loan Combination is involved, to the
         Certificateholders and the related Non-Trust Mortgage Loan
         Noteholder(s)), as a collective whole, on a present value basis (the
         relevant discounting of anticipated collections that will be
         distributable to Certificateholders (or, if a Loan Combination is
         involved, to the Certificateholders and the related Non-Trust Mortgage
         Loan Noteholder(s)), as a collective whole, to be performed at the
         related Mortgage Rate(s)) to acquire title to or possession of the
         Mortgaged Property and to take such actions with respect to the
         affected Mortgaged Property.

         The Special Servicer shall, in good faith, undertake reasonable efforts
to make the determination referred to in the preceding paragraph and may
conclusively rely on the Environmental Assessment referred to above in making
such determination. The cost of any such Environmental Assessment shall be
covered by, and reimbursable as, a Servicing Advance; and if any such
Environmental Assessment so warrants, the Special Servicer shall perform or
cause to be performed such additional environmental testing as it deems
necessary and prudent to determine whether the conditions described in clauses
(i) and (ii) of the preceding paragraph have been satisfied (the cost of any
such additional testing also to be covered by, and reimbursable as, a Servicing
Advance). The cost of any remedial, corrective or other further action
contemplated by clause (i) and/or clause (ii) of the preceding paragraph, shall
be payable out of the related Custodial Account pursuant to Section 3.05(a),
Section 3.05A or Section 3.05B, as applicable (or, in the case of a Mortgaged
Property that secures a Loan Combination, to the extent the funds in the
applicable Loan Combination Custodial Account are insufficient, shall be
advanced by the Master Servicer, subject to Section 3.11(h)).

         (d) If the environmental testing contemplated by Section 3.09(c) above
establishes that any of the conditions set forth in clauses (i) and (ii) of the
first sentence thereof has not been satisfied with respect to any Mortgaged
Property securing a defaulted Mortgage Loan, the Special Servicer shall take
such action as is in accordance with the Servicing Standard (other than
proceeding against the Mortgaged Property). At such time as it deems
appropriate, the Special Servicer may, on behalf of the Trust (and, if a Loan
Combination is involved, the related Non-Trust Mortgage Loan Noteholder(s)),
subject to Section 6.11, Section 6.12 and/or Section 6.13, in each case if and
as applicable, release all or a portion of such Mortgaged Property from the lien
of the related Mortgage.

         (e) The Special Servicer shall report to the Master Servicer, the
Underwriters, the Trustee and, if a Loan Combination is involved, the related
Non-Trust Mortgage Loan Noteholder(s), monthly in writing as to any actions
taken by the Special Servicer with respect to any Mortgaged Property that
represents security for a Specially Serviced Mortgage Loan as to which the
environmental testing contemplated in Section 3.09(c) above has revealed that
any of the conditions set forth in clauses (i) and (ii) of the first sentence
thereof has not been satisfied, in each case until the earlier to occur of
satisfaction of all such conditions and release of the lien of the related
Mortgage on such Mortgaged Property.

         (f) The Special Servicer shall have the right to determine, in
accordance with the Servicing Standard, with respect to any Specially Serviced
Mortgage Loan, the advisability of seeking to obtain a deficiency judgment if
the state in which the related Mortgaged Property is located and the terms of
the affected Mortgage Loan permit such an action, and shall, in accordance with
the Servicing Standard, seek such deficiency judgment if it deems advisable (the
cost of which undertaking shall be covered by, and be reimbursable as, a
Servicing Advance).

         (g) The Master Servicer shall, with the reasonable cooperation of the
Special Servicer, prepare and file information returns with respect to the
receipt of mortgage interest received with respect to any Mortgaged Property
required by Section 6050H of the Code and the reports of foreclosures and
abandonments of any Mortgaged Property and the information returns relating to
cancellation of indebtedness income with respect to any Mortgaged Property
required by Sections 6050J and 6050P of the Code. Such reports shall be in form
and substance sufficient to meet the reporting requirements imposed by Sections
6050H, 6050J and 6050P of the Code.

         (h) As soon as the Special Servicer makes a Final Recovery
Determination with respect to any Specially Serviced Mortgage Loan or REO
Property, it shall promptly notify the Trustee, the Master Servicer and, if a
Loan Combination is involved, the related Non-Trust Mortgage Loan Noteholder(s).
The Special Servicer shall maintain accurate records, prepared by a Servicing
Officer, of each such Final Recovery Determination (if any) and the basis
thereof. Each such Final Recovery Determination (if any) shall be evidenced by
an Officer's Certificate delivered to the Trustee, the Master Servicer and, if a
Loan Combination is involved, the related Non-Trust Mortgage Loan Noteholder(s),
no later than the seventh Business Day following such Final Recovery
Determination.

         SECTION 3.10. Trustee and Custodian to Cooperate; Release of Mortgage
                       Files.

         (a) Upon the payment in full of any Mortgage Loan, or the receipt by
the Master Servicer or the Special Servicer of a notification that payment in
full shall be escrowed in a manner customary for such purposes, the Master
Servicer or the Special Servicer shall promptly notify the Trustee (and, in the
case of a Non-Trust Mortgage Loan, the related Mortgage Loan Noteholder) by a
certification (which certification shall be in the form of a Request for Release
in the form of Exhibit D-1 attached hereto and shall be accompanied by the form
of a release or discharge and shall include a statement to the effect that all
amounts received or to be received in connection with such payment which are

3.04(a), Section 3.04A(a) or Section 3.04B(a), as applicable, have been or will
be so deposited) of a Servicing Officer (a copy of which certification shall be
delivered to the Special Servicer) and shall request delivery to it of the
related Mortgage File and, in the case of a Non-Trust Mortgage Loan, the
original of the Mortgage Note for such Non-Trust Mortgage Loan. Upon receipt of
such certification and request, the Trustee shall release, or cause any related
Custodian to release, the related Mortgage File (and, in the case of a Non-Trust
Mortgage Loan, the Trustee shall cause the related Non-Trust Mortgage Loan
Noteholder to release the Mortgage Note for such Non-Trust Mortgage Loan) to the
Master Servicer or Special Servicer and shall deliver to the Master Servicer or
Special Servicer, as applicable, such release or discharge, duly executed. No
expenses incurred in connection with any instrument of satisfaction or deed of
reconveyance shall be chargeable to the Collection Account or any Custodial
Account.

         (b) If from time to time, and as appropriate for servicing or
foreclosure of any Mortgage Loan, the Master Servicer or the Special Servicer
shall otherwise require any Mortgage File

                                     -174-
<PAGE>

(or any portion thereof) (or the original of the Mortgage Note for a Non-Trust
Mortgage Loan), the Trustee, upon request of the Master Servicer and receipt
from the Master Servicer of a Request for Release in the form of Exhibit D-1
attached hereto signed by a Servicing Officer thereof, or upon request of the
Special Servicer and receipt from the Special Servicer of a Request for Release
in the form of Exhibit D-2 attached hereto, shall release, or cause any related
Custodian to release, such Mortgage File (or such portion thereof) (and, in the
case of a Non-Trust Mortgage Loan, the Trustee shall cause the related Non-Trust
Mortgage Loan Noteholder to release the original of the Mortgage Note for such
Non-Trust Mortgage Loan) to the Master Servicer or the Special Servicer, as the
case may be. Upon return of such Mortgage File (or such portion thereof) to the
Trustee or related Custodian (and, if applicable, such original Mortgage Note
for such Non-Trust Mortgage Loan to the related Non-Trust Mortgage Loan
Noteholder), or the delivery to the Trustee (and, if applicable, to the related
Non-Trust Mortgage Loan Noteholder) of a certificate of a Servicing Officer of
the Special Servicer stating that such Mortgage Loan was liquidated and that all
amounts received or to be received in connection with such liquidation that are
required to be deposited into the related Custodial Account pursuant to Section
3.04(a), Section 3.04A(a) or Section 3.04B(a), as applicable, have been or will
be so deposited, or that the related Mortgaged Property has become an REO
Property, the Request for Release shall be released by the Trustee or related
Custodian to the Master Servicer or the Special Servicer, as applicable.

         (c) Within seven (7) Business Days (or within such shorter period (but
no less than three (3) Business Days) as execution and delivery can reasonably
be accomplished if the Special Servicer notifies the Trustee (and, in the case
of a Loan Combination, the related Non-Trust Mortgage Loan Noteholder(s)) of an
exigency) of the Special Servicer's request therefor, the Trustee shall execute
and deliver to the Special Servicer (or the Special Servicer may execute and
deliver in the name of the Trustee (on behalf of the Certificateholders and, in
the case of the a Mortgaged Property that secures a Loan Combination, the
related Non-Trust Mortgage Loan Noteholder(s)) based on a limited power of

in the form supplied to the Trustee, with respect to any Mortgage Loan, any
court pleadings, requests for trustee's sale or other documents stated by the
Special Servicer to be reasonably necessary to the foreclosure or trustee's sale
in respect of the related Mortgaged Property or to any legal action brought to
obtain judgment against any Mortgagor on the related Mortgage Note or Mortgage
or to obtain a deficiency judgment, or to enforce any other remedies or rights
provided by the related Mortgage Note or Mortgage or otherwise available at law
or in equity or to defend any legal action or counterclaim filed against the

affected Non-Trust Mortgage Loan Noteholder) a certificate of a Servicing
Officer requesting that such pleadings or documents be executed by the Trustee
and certifying as to the reason such documents or pleadings are required and
that the execution and delivery thereof by the Trustee (on behalf of the
Certificateholders and, in the case of a Loan Combination, also on behalf of the
related Non-Trust Mortgage Loan Noteholder(s)) 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. Notwithstanding anything
contained herein to the contrary, neither the Master Servicer nor the Special
Servicer shall, without the Trustee's written consent: (i) initiate any action,
suit or proceeding solely under the Trustee's name without indicating the Master
Servicer's or Special Servicer's, as applicable, representative capacity, or

         SECTION 3.11. Servicing Compensation; Payment of Expenses; Certain
                       Matters Regarding Servicing Advances.

         (a) As compensation for its activities hereunder, the Master Servicer
shall be entitled to receive the Master Servicing Fee with respect to each Trust
Mortgage Loan, each REO Trust Mortgage Loan, each GIC Office Non-Trust Mortgage
Loan and each successor REO Mortgage Loan with respect to a GIC Office Non-Trust
Mortgage Loan. As to each such Mortgage Loan and REO Mortgage Loan, the Master
Servicing Fee shall: (i) accrue from time to time at the related Master
Servicing Fee Rate on the same principal amount as interest accrues from time to
time on such Mortgage Loan or is deemed to accrue from time to time on such REO
Mortgage Loan; and (ii) be calculated on a 30/360 Basis (or, in the event that a
Principal Prepayment in full or other Liquidation Event shall occur with respect
to any such Mortgage Loan or REO Mortgage Loan on a date that is not a Due Date,
on the basis of the actual number of days to elapse from and including the most
recently preceding related Due Date to but excluding the date of such Principal
Prepayment or Liquidation Event in a month consisting of 30 days). The Master
Servicing Fee with respect to any such Mortgage Loan or REO Mortgage Loan shall
cease to accrue if a Liquidation Event occurs in respect thereof. Earned but
unpaid Master Servicing Fees shall be payable monthly, on a loan-by-loan basis,
from payments of interest on each such Mortgage Loan and REO Revenues allocable
as interest on each such REO Mortgage Loan. The Master Servicer shall be
entitled to recover unpaid Master Servicing Fees in respect of any such Mortgage
Loan or REO Mortgage Loan out of that portion of related Insurance Proceeds,
Condemnation Proceeds or Liquidation Proceeds allocable as recoveries of
interest, to the extent permitted by Section 3.05(a), Section 3.05A or Section
3.05B, as applicable, and in the case of a Trust Mortgage Loan or an REO Trust
Mortgage Loan, out of such other amounts as may be permitted by Section 3.05(a).
The right to receive the Master Servicing Fee may not be transferred in whole or
in part except in connection with the transfer of all of the Master Servicer's
responsibilities and obligations under this Agreement. Notwithstanding anything
herein to the contrary, no Master Servicing Fee shall be calculated or payable
hereunder based upon or with respect to the MGM Tower Non-Trust Mortgage Loan or
any successor REO Mortgage Loan with respect thereto.

         (b) Additional master servicing compensation in the form of (i) Net
Default Charges, charges for beneficiary statements or demands, amounts
collected for checks returned for insufficient funds, and any similar fees
(excluding Prepayment Premiums and Yield Maintenance Charges), in each case to
the extent actually paid by a Mortgagor with respect to any Mortgage Loan (or,
in the case of Net Default Charges, any Trust Mortgage Loan) and accrued during
the time that such Mortgage Loan (or, in the case of Net Default Charges, such
Trust Mortgage Loan) was a Performing Mortgage Loan (or, in the case of Net
Default Charges, a Performing Trust Mortgage Loan), (ii) 100% of each
modification fee, extension fee or other similar fee actually paid by a
Mortgagor with respect to a modification, consent, extension, waiver or
amendment agreed to by the Master Servicer pursuant to Section 3.20(c) or
Section 3.08(c), and 100% of any fee actually paid by a Mortgagor in connection
with a defeasance of a Mortgage Loan as contemplated under Section 3.20, and
(iii) 50% of any and all assumption fees and 100% of any and all assumption
application fees and other applicable fees, actually paid by a Mortgagor in
accordance with the related loan documents, with respect to any assumption or
substitution agreement entered into by the Master Servicer on behalf of the
Trust (or, in the case of a Loan Combination, on behalf of the Trust and the
related Non-Trust Mortgage Loan Noteholder(s)) pursuant to Section 3.08(a) or
paid by a Mortgagor with respect to any transfer of an interest in a Mortgagor
pursuant to Section 3.08(a), shall be retained by the Master Servicer or
promptly paid to the Master Servicer by the Special Servicer and such additional
master servicing compensation is not required to be deposited in any

                                     -176-
<PAGE>

Custodial Account. The Master Servicer shall also be entitled to additional
master servicing compensation in the form of (i) Prepayment Interest Excesses
received with respect to the Trust Mortgage Loans; (ii) interest or other income
earned on deposits in the Custodial Accounts in accordance with Section 3.06(b)
(but only to the extent of the Net Investment Earnings, if any, with respect to
such account for each Trust Collection Period, in the case of the Pool Custodial
Account and the MGM Tower Custodial Account, or for each GIC Office Collection
Period, in the case of the GIC Office Custodial Account); and (iii) to the
extent not required to be paid to any Mortgagor under applicable law, any
interest or other income earned on deposits in the Servicing Accounts, the
Reserve Accounts and the Defeasance Deposit Account maintained thereby (but only
to the extent of the Net Investment Earnings, if any, with respect to each such
account for each Trust Collection Period (or, in the case of an Investment
Account that solely relates to the GIC Office Loan Group, for each GIC Office
Collection Period)).

         (c) As compensation for its activities hereunder, the Special Servicer
shall be entitled to receive the Special Servicing Fee with respect to each
Specially Serviced Mortgage Loan and each REO Mortgage Loan. With respect to
each Specially Serviced Mortgage Loan and each REO Mortgage Loan, for any
calendar month (or portion thereof), the Special Servicing Fee shall: (i) accrue
from time to time at the Special Servicing Fee Rate on the same principal amount
as interest accrues from time to time on such Mortgage Loan or is deemed to
accrue from time to time on such REO Mortgage Loan; and (ii) be calculated on a
30/360 Basis (or, in the event that a Principal Prepayment in full or other
Liquidation Event shall occur with respect to any Specially Serviced Mortgage
Loan or REO Mortgage Loan on a date that is not a Due Date, on the basis of the
actual number of days to elapse from and including the most recently preceding
related Due Date to but excluding the date of such Principal Prepayment or
Liquidation Event, in a month consisting of 30 days and, in the case of any
other partial period that does not run from one Due Date through and including
the day immediately preceding the next Due Date, on the basis of the actual
number of days in such period in a month consisting of 30 days). The Special
Servicing Fee with respect to any Specially Serviced Mortgage Loan or REO
Mortgage Loan shall cease to accrue as of the date a Liquidation Event occurs in
respect thereof or it becomes a Corrected Mortgage Loan. Earned but unpaid
Special Servicing Fees in respect of Specially Serviced Trust Mortgage Loans and
REO Trust Mortgage Loans shall be payable monthly out of general collections on
the Mortgage Loans on deposit in the Pool Custodial Account, to the extent
permitted by Section 3.05(a). In addition, earned but unpaid Special Servicing
Fees in respect of a Loan Combination consisting of Specially Serviced Mortgage
Loans or REO Mortgage Loans shall be payable out of collections on such Loan
Combination on deposit in the applicable Loan Combination Custodial Account, to
the extent permitted pursuant to Section 3.05A or Section 3.05B, as applicable.

         As further compensation for its services hereunder, the Special
Servicer shall be entitled to receive the Workout Fee with respect to each
Corrected Mortgage Loan. As to each Corrected Mortgage Loan, subject to the
second following paragraph, the Workout Fee shall be payable from, and shall be
calculated by application of the Workout Fee Rate to, all collections of
principal, interest (other than Default Interest and Additional Interest),
Prepayment Premiums and/or Yield Maintenance Charges received on the subject
Mortgage Loan for so long as it remains a Corrected Mortgage Loan; provided that
no Workout Fee shall be payable from, or based upon the receipt of, Liquidation
Proceeds collected in connection with the acquisition of any Mortgage Loan by
all the Certificateholders (acting together) in exchange for all the
Certificates pursuant to Section 9.01 or the purchase of any Mortgage Loan by a
Purchase Option Holder pursuant to Section 3.18, by the Depositor, Lehman
Brothers, the Special Servicer, a Controlling Class Certificateholder or the
Master Servicer pursuant to Section 9.01, by the

                                     -177-

Depositor pursuant to Section 2.03 or the UBS Mortgage Loan Seller pursuant to
the UBS/Depositor Mortgage Loan Purchase Agreement, by a Non-Trust Mortgage Loan
Noteholder or its designee pursuant to the related Co-Lender Agreement, or by
the holder of a related mezzanine loan pursuant to a purchase right in
connection with a Mortgage Loan default as set forth in the related
intercreditor agreement, or out of any Insurance Proceeds or Condemnation
Proceeds. The Workout Fee with respect to any Corrected Mortgage Loan will cease
to be payable if such Corrected Mortgage Loan again becomes a Specially Serviced
Mortgage Loan or if the related Mortgaged Property becomes an REO Property;
provided that a new Workout Fee will become payable if and when the particular
Mortgage Loan again becomes a Corrected Mortgage Loan. If the Special Servicer
is terminated or removed other than for cause (and other than as a result of an
Event of Default under Sections 7.01(a)(x) or 7.01(a)(xi)) or resigns in
accordance with the first sentence of the first paragraph of Section 6.04, it
shall retain the right to receive any and all Workout Fees payable in respect of
Mortgage Loans that became Corrected Mortgage Loans during the period that it
acted as Special Servicer and were still such at the time of such termination,
removal or resignation (and the successor Special Servicer shall not be entitled
to any portion of such Workout Fees), in each case until the Workout Fee for any
such Mortgage Loan ceases to be payable in accordance with the preceding
sentence.

         As further compensation for its activities hereunder, the Special
Servicer shall also be entitled to receive the Liquidation Fee with respect to
each Specially Serviced Mortgage Loan as to which it receives a full, partial or
discounted payoff and, subject to the provisos to the next sentence, each
Specially Serviced Mortgage Loan and REO Property as to which it receives Net
Liquidation Proceeds. As to each such Specially Serviced Mortgage Loan or REO
Property, subject to the following paragraph, the Liquidation Fee shall be
payable from, and shall be calculated by application of the Liquidation Fee Rate
to, such full, partial or discounted payoff and/or Net Liquidation Proceeds
(exclusive of any portion of such payoff or proceeds that represents Default
Interest and/or Additional Interest); provided that no Liquidation Fee shall be
payable (i) with respect to any Specially Serviced Mortgage Loan that becomes a
Corrected Mortgage Loan or (ii) from, or based upon the receipt of, Liquidation
Proceeds collected in connection with the acquisition of any Specially Serviced
Mortgage Loan or REO Property by all the Certificateholders (acting together) in
exchange for all the Certificates pursuant to Section 9.01 or the purchase of
any Specially Serviced Mortgage Loan or REO Property by a Purchase Option Holder
pursuant to Section 3.18, by the Depositor, Lehman Brothers, the Special
Servicer, a Controlling Class Certificateholder or the Master Servicer pursuant
to Section 9.01, by a Non-Trust Mortgage Loan Noteholder or its designee
pursuant to the related Co-Lender Agreement, by the Depositor pursuant to
Section 2.03 or the UBS Mortgage Loan Seller pursuant to the UBS/Depositor
Mortgage Loan Purchase Agreement in connection with a Material Document Defect
or a Material Breach (in either such case, prior to the expiration of the
Initial Resolution Period plus the applicable Resolution Extension Period for
the subject Material Document Defect or Material Breach, as applicable, that
gave rise to the particular repurchase obligation) or by the holder of a related
mezzanine loan pursuant to a purchase right in connection with a Mortgage Loan
default as set forth in the related intercreditor agreement; and provided,
further, that, in connection with any purchase by the Depositor pursuant to
Section 2.03 or the UBS Mortgage Loan Seller pursuant to the UBS/Depositor
Mortgage Loan Purchase Agreement in connection with a Material Document Defect
or a Material Breach (in either case, subsequent to the expiration of the
Initial Resolution Period plus the Resolution Extension Period for the subject
Material Document Defect or Material Breach, as applicable, that gave rise to
the particular repurchase obligation), the Liquidation Fee shall equal 1% of the
Stated Principal Balance of the repurchased Trust Mortgage Loan (or, if an REO
Property is being repurchased, 1% of the Stated Principal Balance of the related
REO Trust Mortgage Loan).

                                     -178-
<PAGE>

         Notwithstanding the foregoing, any Workout Fee and/or Liquidation Fee
payable in accordance with the two preceding paragraphs with respect to Mortgage
Loans or REO Mortgage Loans that comprise a Loan Combination shall be paid from
collections received on such Loan Combination on deposit in the related Loan
Combination Custodial Account, to the extent permitted under Section 3.05A or
Section 3.05B, as applicable.

         Notwithstanding anything to the contrary herein, a Liquidation Fee and
a Workout Fee relating to the same Mortgage Loan shall not be paid from the same
proceeds with respect to such Mortgage Loan.

         The Special Servicer's right to receive the Special Servicing Fee, the
Workout Fee and the Liquidation Fee may not be transferred in whole or in part
except in connection with the transfer of all of the Special Servicer's
responsibilities and obligations under this Agreement.

         (d) Additional special servicing compensation in the form of (i) Net
Default Charges actually collected with respect to any Trust Mortgage Loan or
REO Trust Mortgage Loan that accrued while the subject loan was a Specially
Serviced Trust Mortgage Loan or an REO Trust Mortgage Loan, (ii) with respect to
any Specially Serviced Mortgage Loan, 100% of any and all assumption fees,
assumption application fees and other applicable fees, actually paid by a
Mortgagor in accordance with the related loan documents, with respect to any
assumption or substitution agreement entered into by the Special Servicer on
behalf of the Trust (or, in the case of a Loan Combination, on behalf of the
Trust and the related Non-Trust Mortgage Loan Noteholder(s)) pursuant to Section
3.08(b) or paid by a Mortgagor with respect to any transfer of an interest in a
Mortgagor pursuant to Section 3.08(b), (iii) with respect to any Performing
Mortgage Loan, 50% of any and all assumption fees actually paid by a Mortgagor
in accordance with the related loan documents, with respect to any assumption or
substitution agreement entered into by the Master Servicer on behalf of the
Trust (or, in the case of a Loan Combination, on behalf of the Trust and the
related Non-Trust Mortgage Loan Noteholder(s)) pursuant to Section 3.08(a) or
paid by a Mortgagor with respect to any transfer of an interest in a Mortgagor
pursuant to Section 3.08(a), and (iv) any and all modification fees, consent
fees, extension fees and similar fees actually collected on the Mortgage Loans
that are not otherwise payable to the Master Servicer as additional master
servicing compensation pursuant to Section 3.11(b), shall be retained by the
Special Servicer or promptly paid to the Special Servicer by the Master
Servicer, as the case may be, and shall not be required to be deposited in any
Custodial Account pursuant to Section 3.04(a), Section 3.04A(a) or Section
3.04B(a), as applicable. The Special Servicer shall also be entitled to
additional special servicing compensation in the form of interest or other
income earned on deposits in any REO Account, if established, in accordance with
Section 3.06(b) (but only to the extent of the Net Investment Earnings, if any,
with respect to such account for each Trust Collection Period, in the case of
the Pool REO Account and the MGM Tower REO Account, or for each GIC Office
Collection Period, in the case of the GIC Office REO Account).

         (e) The Master Servicer and the Special Servicer shall each be required
to pay out of its own funds all expenses incurred by it in connection with its
servicing activities hereunder (including payment of any amounts due and owing
to any of its Sub-Servicers and the premiums for any blanket policy obtained by
it insuring against hazard losses pursuant to Section 3.07(b)), if and to the
extent such expenses are not payable directly out of any of the Custodial
Accounts or, in the case of the Special Servicer, any of the REO Accounts, and
neither the Master Servicer nor the Special Servicer shall be entitled to
reimbursement for such expenses except as expressly provided in this Agreement.

         (f) If the Master Servicer or Special Servicer is required under any
provision of this Agreement to make a Servicing Advance, but it does not do so
within 15 days after such Advance is required to be made, the Trustee shall, if
it has actual knowledge of such failure on the part of the Master Servicer or
Special Servicer, as the case may be,, give written notice of such failure to,
as applicable, the Master Servicer or the Special Servicer. If such Servicing
Advance is not made by the Master Servicer or the Special Servicer, as
applicable, within three (3) Business Days after such notice is given to the
Master Servicer or the Special Servicer, as the case may be, then (subject to
Section 3.11(h)) the Trustee shall make such Servicing Advance. If the Trustee
fails to make any Servicing Advance required to be made under this Agreement,
then (subject to Section 3.11(h)) the Fiscal Agent shall make such Servicing
Advance within one (1) Business Day of such failure by the Trustee and, if so
made, the Trustee shall be deemed not to be in default under this Agreement.

         (g) The Master Servicer, the Special Servicer, the Trustee and the
Fiscal Agent shall each be entitled to receive interest at the Reimbursement
Rate in effect from time to time, compounded annually, accrued on the amount of
each Servicing Advance made thereby (with its own funds) for so long as such
Servicing Advance is outstanding, such interest to be payable: (i) first, in
accordance with Sections 3.05(a) and 3.26, out of any Default Charges on deposit
in the Pool Custodial Account that were collected on or in respect of the
particular Trust Mortgage Loan or REO Trust Mortgage Loan as to which such
Servicing Advance relates (provided that such Default Charges will only be
applied to pay interest accrued on such Servicing Advance through the date that
such Default Charges were received); and (ii) then, if and to the extent that
such Default Charges are insufficient to cover such interest, but not before the
related Advance has been reimbursed pursuant to this Agreement, out of general
collections on the Trust Mortgage Loans and REO Trust Mortgage Loans on deposit
in the Pool Custodial Account; provided that, if such Servicing Advance was made
with respect to a Loan Combination or any related Mortgaged Property, then such
interest shall first be payable out of amounts on deposit in the related Loan
Combination Custodial Account in accordance with Section 3.05A or Section 3.05B,
as applicable. The Master Servicer shall reimburse itself, the Special Servicer,
the Trustee or the Fiscal Agent, as appropriate, in accordance with Section
3.03, Section 3.05(a), Section 3.05A or Section 3.05B, as applicable, for any
Servicing Advance as soon as practicable after funds available for such purpose
are deposited in the applicable Custodial Account. Notwithstanding the
foregoing, upon a determination that a previously made Servicing Advance is a
Nonrecoverable Servicing Advance, instead of obtaining reimbursement out of
general collections on the Mortgage Pool immediately, any of the Master
Servicer, the Special Servicer, the Trustee or the Fiscal Agent, as applicable,
may, in its sole discretion, elect to obtain reimbursement for such
Nonrecoverable Servicing Advance over a period of time (not to exceed 12 months
or such longer period of time as is approved in writing by the Controlling Class
Representative) and the unreimbursed portion of such Servicing Advance will
accrue interest at the Reimbursement Rate in effect from time to time. At any
time after such a determination to obtain reimbursement over time in accordance
with the preceding sentence, the Master Servicer, the Special Servicer, the
Trustee or the Fiscal Agent, as applicable, may, in its sole discretion, decide
to obtain reimbursement immediately. The fact that a decision to recover such
Nonrecoverable Servicing Advance over time, or not to do so, benefits some
Classes of Certificateholders to the detriment of other Classes shall not
constitute a violation of the Servicing Standard by the Master Servicer, or a
breach of any fiduciary duty owed to the Certificateholders by the Trustee or
the Fiscal Agent, or a breach of any other contractual obligation owed to the
Certificateholders by any party to this Agreement.

         (h) Notwithstanding anything herein to the contrary, none of the Master
Servicer, the Special Servicer, the Trustee or the Fiscal Agent shall be
required to make out of its own funds any

                                     -180-
<PAGE>

Servicing Advance that would, if made, constitute a Nonrecoverable Servicing
Advance. The determination by the Master Servicer or the Special Servicer that
it has made (or, in the case of the Special Servicer, that the Master Servicer
has made) a Nonrecoverable Servicing Advance or that any proposed Servicing
Advance, if made, would constitute a Nonrecoverable Servicing Advance, shall be
made in accordance with the Servicing Standard and shall be evidenced by an
Officer's Certificate delivered promptly to the Trustee and the Depositor (and,
in the case of a Servicing Advance with respect to a Loan Combination, the
related Non-Trust Mortgage Loan Noteholder(s)), setting forth the basis for such
determination, together with a copy of any appraisal of the related Mortgaged
Property or REO Property, as the case may be (which appraisal shall be an
expense of the Trust, shall take into account the factors specified in Section
3.18) and shall have been conducted by an Independent Appraiser in accordance
with the standards of the Appraisal Institute within the twelve months preceding
such determination of nonrecoverability), and further accompanied by related
Mortgagor operating statements and financial statements, budgets and rent rolls
of the related Mortgaged Property (to the extent available and/or in the Master
Servicer's or the Special Servicer's possession) and any engineers' reports,
environmental surveys or similar reports that the Master Servicer or the Special
Servicer may have obtained and that support such determination. If the Master
Servicer intends to obtain an appraisal in connection with the foregoing, the
Master Servicer shall so notify the Special Servicer and consult with the
Special Servicer regarding such appraisal. The Trustee and the Fiscal Agent
shall be entitled to rely, conclusively, on any determination by the Master
Servicer or the Special Servicer that a Servicing Advance, if made, would be a
Nonrecoverable Servicing Advance; provided, however, that if the Master Servicer
or the Special Servicer has failed to make a Servicing Advance for reasons other
than a determination by the Master Servicer or the Special Servicer, as
applicable, that such Servicing Advance would be a Nonrecoverable Advance, the
Trustee or the Fiscal Agent, as applicable, shall make such Servicing Advance
within the time periods required by Section 3.11(f) unless the Trustee or the
Fiscal Agent, in good faith, makes a determination that such Servicing Advance
would be a Nonrecoverable Advance.

         (i) Notwithstanding anything set forth herein to the contrary, the
Master Servicer shall (at the direction of the Special Servicer if a Specially
Serviced Mortgage Loan or an REO Property is involved) pay directly out of the
Pool Custodial Account, the GIC Office Custodial Account or the MGM Tower
Custodial Account, as applicable, in accordance with Sections 3.05(a), 3.05A and
3.05B, any servicing expense that, if advanced by the Master Servicer or the
Special Servicer, would constitute a Nonrecoverable Servicing Advance; provided
that the Master Servicer (or the Special Servicer, if a Specially Serviced
Mortgage Loan or an REO Property is involved) has determined in accordance with
the Servicing Standard that making such payment, in the case of withdrawals from
a Loan Combination Custodial Account, is in the best interests of the
Certificateholders and the related Non-Trust Mortgage Loan Noteholder(s) (as a
collective whole), or, in the case of withdrawals from the Pool Custodial
Account, is in the best interests of the Certificateholders (as a collective
whole), as evidenced in each case by an Officer's Certificate delivered promptly
to the Trustee, the Depositor, the Controlling Class Representative and any
affected Non-Trust Mortgage Loan Noteholder(s), setting forth the basis for such
determination and accompanied by any information that such Person may have
obtained that supports such determination. A copy of any such Officer's
Certificate (and accompanying information) of the Master Servicer shall also be
promptly delivered to the Special Servicer, and a copy of any such Officer's
Certificate (and accompanying information) of the Special Servicer shall also be
promptly delivered to the Master Servicer. The Master Servicer may conclusively
rely on any information in this regard provided by the Special Servicer (if
other than the Master Servicer or an Affiliate thereof).

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

         (a) The Special Servicer shall perform or cause to be performed a
physical inspection of a Mortgaged Property as soon as practicable after the
related Mortgage Loan becomes a Specially Serviced Mortgage Loan and annually
thereafter for so long as the related Mortgage Loan remains a Specially Serviced
Mortgage Loan, the cost of which shall be paid by the Master Servicer, at the
direction of the Special Servicer, and shall be reimbursable as a Servicing
Advance. In addition, the Special Servicer shall perform or cause to be
performed a physical inspection of each of the REO Properties at least once per
calendar year, the cost of which shall be paid by the Master Servicer, at the
direction of the Special Servicer, and shall be reimbursable as a Servicing
Advance. Beginning in 2004, the Master Servicer shall at its expense perform or
cause to be performed a physical inspection of each Mortgaged Property securing
a Performing Mortgage Loan: (i) at least once every two calendar years in the
case of Mortgaged Properties securing Performing Mortgage Loans that have
outstanding principal balances of (or Mortgaged Properties having allocated loan
amounts of) $2,000,000 or less; and (ii) at least once every calendar year in
the case of all other such Mortgaged Properties; provided, that the Master
Servicer will not be required to perform or cause to be performed an inspection
on a Mortgaged Property if such Mortgaged Property has been inspected by the
Master Servicer or the Special Servicer in the preceding six months. The Master
Servicer and the Special Servicer shall each promptly prepare or cause to be
prepared and deliver to the Trustee, the related Non-Trust Mortgage Loan
Noteholder(s) (if the subject Mortgaged Property secures a Loan Combination) and
each other a written report of each such inspection performed by it that sets
forth in detail the condition of the Mortgaged Property and that specifies the
existence of: (i) any sale, transfer or abandonment of the Mortgaged Property of
which the Master Servicer or the Special Servicer, as applicable, is aware, (ii)
any change in the condition or value of the Mortgaged Property that the Master
Servicer or the Special Servicer, as applicable, in its reasonable, good faith
judgment, considers material, or (iii) any waste committed on the Mortgaged
Property. The Master Servicer and Special Servicer shall each forward copies of
any such inspection reports prepared by it to the Underwriters and the
Controlling Class Representative upon request, subject to payment of a
reasonable fee.

         The Special Servicer, in the case of each Specially Serviced Mortgage
Loan and each REO Mortgage Loan, and the Master Servicer, in the case of each
Performing Mortgage Loan, shall each, consistent with the Servicing Standard,
use reasonable efforts to obtain quarterly, annual and other periodic operating
statements and rent rolls with respect to each of the related Mortgaged
Properties and REO Properties. The Special Servicer shall, promptly following
receipt, deliver copies of the operating statements and rent rolls received or
obtained by it to the Master Servicer, and the Master Servicer shall promptly
deliver copies of the operating statements and rent rolls received or obtained
by it to the Trustee, the Special Servicer, the related Non-Trust Mortgage Loan
Noteholder(s) (if the subject Mortgaged Property secures a Loan Combination) or
any Controlling Class Certificateholder, in each case upon request. The Special
Servicer shall, promptly following receipt, deliver copies of the materials
received or obtained by it pursuant to the foregoing sentence to the Master
Servicer, and the Master Servicer shall promptly deliver copies of all such
materials received or obtained by it pursuant to the foregoing sentence and this
sentence to the Trustee, the Special Servicer, any Controlling Class
Certificateholder and any Non-Trust Mortgage Loan Noteholder, in each case upon
request.

         Within 30 days after receipt by the Master Servicer of any annual
operating statements with respect to any Mortgaged Property or REO Property, the
Master Servicer with respect to a

                                     -182-

Performing Mortgage Loan and the Special Servicer with respect to a Specially
Serviced Mortgage Loan or an REO Mortgage Loan shall prepare or update and
forward to the Trustee a CMSA NOI Adjustment Worksheet for such Mortgaged
Property or REO Property (with, upon request, the annual operating statements
attached thereto as an exhibit).

         The Master Servicer with respect to a Performing Mortgage Loan and the
Special Servicer with respect to a Specially Serviced Mortgage Loan or an REO
Mortgage Loan shall prepare and maintain one CMSA Operating Statement Analysis
Report for each Mortgaged Property and REO Property. The CMSA Operating
Statement Analysis Report for each such Mortgaged Property and REO Property is
to be updated by the Master Servicer or Special Servicer, as applicable, within
30 days after its receipt of updated operating statements for a Mortgaged
Property or REO Property, as the case may be. The Master Servicer or Special
Servicer, as applicable, shall use the "Normalized" column from the CMSA NOI
Adjustment Worksheet for any Mortgaged Property or REO Property, as the case may
be, to update and normalize the corresponding annual year-end information in the
CMSA Operating Statement Analysis Report and shall use any annual operating
statements and related data fields received with respect to any Mortgaged
Property or REO Property, as the case may be, to prepare the CMSA NOI Adjustment
Worksheet for such property. Copies of CMSA Operating Statement Analysis Reports
and CMSA NOI Adjustment Worksheets are to be forwarded to the Trustee
automatically (on a monthly basis) during any period in respect of which
Exchange Act Reports are being filed as to the Trust with the Commission, and
are otherwise to be made available by the Master Servicer to the Trustee, the
Special Servicer and any Controlling Class Certificateholder, in each case upon
request.

         (b) Not later than 2:00 p.m. (New York City time) on the second
Business Day prior to each Trust Determination Date, the Special Servicer shall
deliver or cause to be delivered to the Master Servicer the following reports

Specially Serviced Trust Mortgage Loans, any Corrected Trust Mortgage Loans: (i)
a CMSA Delinquent Loan Status Report; (ii) a Loan Payoff Notification Report;
(iii) a CMSA Historical Liquidation Report; (iv) a CMSA Historical Loan
Modification and Corrected Mortgage Loan Report; and (v) a CMSA REO Status
Report.

         (c) Not later than 2:00 p.m. (New York City time) on the first Business
Day prior to each Distribution Date, the Master Servicer shall deliver or cause
to be delivered to the Trustee, the Rating Agencies, the Special Servicer and,
upon request, any Controlling Class Certificateholder: (i) the most recent CMSA

on Advances in accordance with Section 3.11(g) and/or 4.03(d), such information
to be presented on a loan-by-loan basis.

         If the Master Servicer determines, in its reasonable judgment, that
information regarding the Trust Mortgage Loans and REO Properties (in addition
to the information otherwise required to be contained in the CMSA Investor
Reporting Package) should be disclosed to Certificateholders and Certificate
Owners, then it shall forward such information in the form of a Supplemental
Report to the Trustee in accordance with Section 4.02(a).

         (d) The Special Servicer shall deliver to the Master Servicer the
reports set forth in Section 3.12(b) in an electronic format reasonably
acceptable to the Special Servicer and the Master Servicer, and the Master
Servicer shall deliver to the Trustee, the Special Servicer and, upon request,
any Controlling Class Certificateholder the reports set forth in Section 3.12(c)
in an electronic format reasonably acceptable to the Master Servicer and the
Trustee. The Master Servicer may, absent manifest error, conclusively rely on
the reports to be provided by the Special Servicer pursuant to Section 3.12(b).
The Trustee may, absent manifest error, conclusively rely on the reports to be
provided by the Master Servicer pursuant to Section 3.12(c) to the extent that
the underlying information is solely within the control of the Master Servicer
or the Special Servicer. In the case of information or reports to be furnished

that such information is based on reports to be provided by the Special Servicer
pursuant to Section 3.12(b) and/or that such reports are to be prepared and
delivered by the Special Servicer pursuant to Section 3.12(b), so long as the
Master Servicer and the Special Servicer are not the same Person or Affiliates,
the Master Servicer shall have no obligation to provide such information or
reports to the Trustee until it has received such information or reports from
the Special Servicer, and the Master Servicer shall not be in default hereunder
due to a delay in providing the reports required by Section 3.12(c) caused by
the Special Servicer's failure to timely provide any report required under
Section 3.12(b) of this Agreement.

         (e) The preparation and maintenance by the Master Servicer and the
Special Servicer of all the reports specified in this Section 3.12, including
the calculations made therein, shall be done in accordance with CMSA standards
to the extent applicable thereto.

         SECTION 3.12A. Delivery of Certain Reports to the Non-Trust Mortgage
                        Loan Noteholders.

         (a) The Master Servicer shall promptly deliver to each Non-Trust

2:00 p.m. (New York City time) on the second Business Day prior to each
applicable Determination Date, the Special Servicer shall deliver or cause to be

the Special Servicer pursuant to Section 3.12A(b). In the case of information or
reports to be furnished by the Master Servicer to a Non-Trust Mortgage Loan
Noteholder pursuant to Section 3.12B(a), to the extent that such information is
based on reports to be provided by the Special Servicer pursuant to Section
3.12A(b) and/or that such reports are to be prepared and delivered by the

and the Special Servicer are not the same Person or Affiliates, the Master
Servicer shall have no obligation to provide such information or reports until
it has received such information or reports from the Special Servicer, and the

Agreement.

         (e) The preparation and maintenance by the Master Servicer and the
Special Servicer of all the reports specified in this Section 3.12A, including

         (b) The Master Servicer shall only be obligated to deliver the
statements, reports and information contemplated by Section 3.12B(a) to the
extent it receives the necessary underlying information from the Special
Servicer and shall not be liable for its failure to deliver such statements,
reports and information on the prescribed due dates, to the extent caused by the
failure of the Special Servicer to deliver timely such underlying information.
Nothing herein shall obligate the Master Servicer or the Special Servicer to
violate any applicable law prohibiting disclosure of information with respect to
the related Mortgagor, and the failure of the Master Servicer or the Special
Servicer to disseminate information for such reason shall not be a breach
hereunder.

         Absent manifest error of which it has actual knowledge, neither the
Master Servicer nor the Special Servicer shall be responsible for the accuracy
or completeness of any information supplied to it by a Mortgagor, a Mortgage
Loan Seller or third party that is included in any reports, statements,
materials or information prepared or provided by the Master Servicer or the
Special Servicer, as applicable, pursuant to this Agreement. Neither the Master
Servicer nor the Special Servicer shall have any obligation to verify the
accuracy or completeness of any information provided by a Mortgagor, a Mortgage
Loan Seller, a third party or each other.

         SECTION 3.13. Annual Statement as to Compliance.

         Each of the Master Servicer and the Special Servicer shall deliver to
the Trustee, the Rating Agencies, the Depositor, the Underwriters, each
Non-Trust Mortgage Loan Noteholder and each other, on or before April 30 of each

contemplated by the last sentence of this Section 3.13), an Officer's
Certificate (the "Annual Performance Certification") stating, as to the signer
thereof, that (i) a review of the activities of the Master Servicer or the
Special Servicer, as the case may be, during the preceding calendar year (or, in
the case of the first such certification, during the period from the Closing
Date to December 31, 2004, inclusive) and, in particular, of its performance
under this Agreement, has been made under such officer's supervision, (ii) to
the best of such officer's knowledge, based on such review, the Master Servicer
or the Special Servicer, as the case may be, has fulfilled all of its material
obligations under this Agreement in all material respects throughout such
preceding calendar year or portion thereof (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), and (iii) the Master Servicer
or the Special Servicer, as- the case may be, has received no notice regarding
the qualification, or challenging the status, of any REMIC Pool as a REMIC or
the Grantor Trust as a grantor trust, from the IRS or any other governmental
agency or body (or, if it has received any such notice, specifying the details
thereof). Notwithstanding the timing provided for in the first sentence of this
paragraph, if (as confirmed in writing by the Depositor) the Depositor is
required to file a Form 10-K with the Commission in respect of the Trust
covering any particular calendar year, then the Annual Performance Certification
to be delivered by each of the Master Servicer and the Special Servicer during
the following year, shall be delivered on or before March 15 of such following
year; and the Master Servicer and the Special Servicer are hereby notified that
the Depositor is required to file a Form 10-K with the Commission in respect of
the Trust covering calendar year 2004.

         SECTION 3.14. Reports by Independent Public Accountants.

         On or before April 30 of each year, beginning in 2005 (or, as to any
such year, such earlier date as is contemplated by the last sentence of this
paragraph), each of the Master Servicer and

                                     -186-
<PAGE>

the Special Servicer at its expense shall cause a firm of independent public
accountants (which may also render other services to the Master Servicer or the
Special Servicer) that is a member of the American Institute of Certified Public
Accountants to furnish a statement (the "Annual Accountants' Report") to the
Trustee, the Rating Agencies, the Depositor, the Underwriters, each Non-Trust
Mortgage Loan Noteholder and each other, to the effect that (i) such firm has
obtained a letter of representation regarding certain matters from the
management of the Master Servicer or the Special Servicer, as applicable, which
includes an assertion that the Master Servicer or the Special Servicer, as
applicable, has complied with certain minimum mortgage loan servicing standards
(to the extent applicable to commercial and multifamily mortgage loans),
identified in the Uniform Single Attestation Program for Mortgage Bankers
established by the Mortgage Bankers Association of America, with respect to the
servicing of commercial and multifamily mortgage loans during the most recently
completed calendar 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. In rendering its report such firm may rely, as to matters
relating to the direct servicing of commercial and multifamily mortgage loans by
sub-servicers, upon comparable reports of firms of independent certified public
accountants rendered (within one year of such report) on the basis of
examinations conducted in accordance with the same standards with respect to
those sub-servicers. Notwithstanding the timing provided for in the first
sentence of this paragraph, if (as confirmed in writing by the Depositor) the
Depositor is required to file a Form 10-K with the Commission in respect of the
Trust covering any particular calendar year, then the Annual Accountants' Report
to be delivered on behalf of each of the Master Servicer and the Special
Servicer during the following year, shall be delivered on or before March 15 of
such following year; and the Master Servicer and the Special Servicer are hereby
notified that the Depositor is required to file a Form 10-K with the Commission
in respect of the Trust covering calendar year 2004.

         The Master Servicer and the Special Servicer, to the extent applicable,
will reasonably cooperate with the Depositor in conforming any reports delivered
pursuant to this Section 3.14 to requirements imposed by the Commission on the
Depositor in connection with the Depositor's reporting requirements in respect
of the Trust Fund pursuant to the Exchange Act, provided that the Master
Servicer and Special Servicer shall each be entitled to charge the Depositor for
any reasonable additional costs and expenses incurred in affording the Depositor
such cooperation.

         SECTION 3.15. Access to Certain Information.

         (a) Each of the Master Servicer and the Special Servicer shall afford
to the Trustee, the Underwriters, the Rating Agencies, the Depositor, any
Certificateholder, any Non-Trust Mortgage Loan Noteholder and any Certificate
Owner (identified as such to the reasonable satisfaction of the Master Servicer
or the Special Servicer, as the case may be), and to the OTS, the FDIC and any
other banking or insurance regulatory authority that may exercise authority over
any Certificateholder, any Certificate Owner (identified as such to the
reasonable satisfaction of the Master Servicer or the Special Servicer, as the
case may be) or any Non-Trust Mortgage Loan Noteholder, access to any records
regarding the Mortgage Loans and the servicing thereof within its control (which
access shall be limited, in the case of any Non-Trust Mortgage Loan Noteholder
or any regulatory authority seeking such access in respect of a Non-Trust
Mortgage Loan Noteholder, to records relating to the related Non-Trust Mortgage
Loan), except to the extent it is prohibited from doing so by applicable law or
contract or to the extent such information is subject to a privilege under
applicable law to be asserted on behalf of the

                                     -187-
<PAGE>

Certificateholders or the Non-Trust Mortgage Loan Noteholders. Such access shall
be afforded only upon reasonable prior written request and during normal
business hours at the offices of the Master Servicer or the Special Servicer, as
the case may be, designated by it.

         In connection with providing or granting any information or access
pursuant to the prior paragraph to a Certificateholder, a Certificate Owner, a
Non-Trust Mortgage Loan Noteholder or any regulatory authority that may exercise
authority over a Certificateholder, a Certificate Owner or a Non-Trust Mortgage
Loan Noteholder, the Master Servicer and the Special Servicer each may require
payment from such Certificateholder, a Certificate Owner or a Non-Trust Mortgage
Loan Noteholder of a sum sufficient to cover the reasonable costs and expenses
of providing such information or access, including copy charges and reasonable
fees for employee time and for space; provided that no charge may be made if
such information or access was required to be given or made available under
applicable law. In connection with providing Certificateholders and Certificate
Owners access to the information described in the preceding paragraph, the
Master Servicer and the Special Servicer shall require (prior to affording such
access) a written confirmation executed by the requesting Person substantially
in such form as may be reasonably acceptable to the Master Servicer or the
Special Servicer, as the case may be, generally to the effect that such Person
is a Holder of Certificates or a beneficial holder of Book-Entry Certificates
and will keep such information confidential.

         Upon the reasonable request of any Certificateholder, or any
Certificate Owner identified to the Master Servicer to the Master Servicer's
reasonable satisfaction, the Master Servicer may provide (or forward
electronically) (at the expense of such Certificateholder or Certificate Owner)
copies of any operating statements, rent rolls and financial statements obtained
by the Master Servicer or the Special Servicer; provided that, in connection
therewith, the Master Servicer shall require a written confirmation executed by
the requesting Person substantially in such form as may be reasonably acceptable
to the Master Servicer, generally to the effect that such Person is a Holder of
Certificates or a beneficial holder of Book-Entry Certificates and will keep
such information confidential.

         (b) No less often than on a monthly basis, upon reasonable prior notice
and during normal business hours, each of the Master Servicer and the Special
Servicer shall, without charge, make a knowledgeable Servicing Officer available
to answer questions from (i) the Controlling Class Representative regarding the
performance and servicing of the Mortgage Loans and/or the REO Properties for
which the Master Servicer or the Special Servicer, as the case may be, is
responsible and (ii) from the GIC Office Subordinate Non-Trust Mortgage Loan
Noteholder, if and for so long as it constitutes the GIC Office Controlling
Noteholder, regarding the performance and servicing of the GIC Office Loan Group
and/or the GIC Office REO Properties, if the Master Servicer or the Special
Servicer, as the case may be, is responsible for the servicing thereof. Except
as provided in the following sentence, in connection with providing the
Controlling Class Representative with the information described in the preceding
sentence, the Master Servicer and the Special Servicer shall require (prior to
providing such information for the first time to such Controlling Class
Representative) a written confirmation executed by the Controlling Class
Representative, in the form of Exhibit O attached hereto, generally to the
effect that such Person will keep any information received by it from time to
time pursuant to this Agreement confidential (other than with respect to
communications with the Controlling Class). In the case of the initial
Controlling Class Representative, upon its or an Affiliate's acquisition of the
Class T Certificates, such entity shall be deemed to have agreed to keep all
non-public information received by it in such capacity from time to time
pursuant to this Agreement confidential, subject to applicable law.

         SECTION 3.16. Title to REO Property; REO Accounts.

         (a) If title to any Mortgaged Property is acquired, the deed or
certificate of sale shall be issued to the Trustee or its nominee on behalf of
the Certificateholders and, in the case of the GIC Office Mortgaged Property or
the MGM Tower Mortgaged Property, on behalf of the related Non-Trust Mortgage
Loan Noteholder(s). If, pursuant to Section 3.09(b), the Special Servicer formed
or caused to be formed, at the expense of the Trust, a single member limited
liability company (of which the Trust is the sole member) for the purpose of
taking title to one or more REO Properties pursuant to this Agreement, then
(subject to the interests of any affected Non-Trust Mortgage Loan Noteholder),
the deed or certificate of sale with respect to any such REO Property shall be
issued to such single member limited liability company. The limited liability
company shall be a manager-managed limited liability company, with the Special
Servicer to serve as the initial manager to manage the property of the limited
liability company, including any applicable REO Property, in accordance with the
terms of this Agreement as if such property was held directly in the name of the
Trust or Trustee under this Agreement.

         The Special Servicer, on behalf of the Trust Fund and, in the case of
any GIC Office REO Property or MGM Tower REO Property, the related Non-Trust
Mortgage Loan Noteholder(s), shall sell any REO Property by the end of the third
calendar year following the calendar year in which REMIC I acquires ownership of
such REO Property for purposes of Section 860G(a)(8) of the Code, unless the
Special Servicer either (i) applies, more than 60 days prior to the end of such
third succeeding year, for and is granted an extension of time (an "REO
Extension") by the IRS to sell such REO Property or (ii) obtains for the Trustee
an Opinion of Counsel, addressed to the Trustee, the Special Servicer and the
Master Servicer, to the effect that the holding by REMIC I of such REO Property
subsequent to the end of such third succeeding year will not result in the
imposition of taxes on "prohibited transactions" (as defined in Section 860F of
the Code) of any REMIC Pool or cause any REMIC Pool to fail to qualify as a
REMIC at any time that any Certificates are outstanding. If the Special Servicer
is granted the REO Extension contemplated by clause (i) of the immediately
preceding sentence or obtains the Opinion of Counsel contemplated by clause (ii)
of the immediately preceding sentence, the Special Servicer shall sell the
subject REO Property within such extended period as is permitted by such REO
Extension or such Opinion of Counsel, as the case may be. Any expense incurred
by the Special Servicer in connection with its obtaining the REO Extension
contemplated by clause (i) of the second preceding sentence or its obtaining the
Opinion of Counsel contemplated by clause (ii) of the second preceding sentence,
or for the creation of and the operating of a single member limited liability
company, shall be covered by, and reimbursable as, a Servicing Advance.

         (b) The Special Servicer shall segregate and hold all funds collected
and received in connection with any REO Property separate and apart from its own
funds and general assets. If an REO Acquisition shall occur in respect of any
Mortgaged Property (other than the GIC Office Mortgaged Property or the MGM
Tower Mortgaged Property), the Special Servicer shall establish and maintain one
or more accounts (collectively, the "Pool REO Account"), to be held on behalf of
the Trustee in trust for the benefit of the Certificateholders, for the
retention of revenues and other proceeds derived from each REO Property (other
than any GIC Office REO Property or MGM Tower REO Property). If such REO
Acquisition occurs with respect to the GIC Office Mortgaged Property or the MGM
Tower Mortgaged Property, then the Special Servicer shall establish an REO
Account solely with respect to such property (the "GIC Office REO Account", in
the case of the GIC Office Mortgaged Property, and the "MGM Tower REO Account,"
in the case of the MGM Tower Mortgaged Property), to be held for the benefit of

                                     -189-
<PAGE>

the Certificateholders and the related Non-Trust Mortgage Loan Noteholder(s).
The Pool REO Account and each Loan Combination REO Account shall each be an
Eligible Account. The Special Servicer shall deposit, or cause to be deposited,
in the applicable REO Account, upon receipt, all REO Revenues, Insurance
Proceeds, Condemnation Proceeds and Liquidation Proceeds received in respect of
any REO Property. Funds in an REO Account (other than any such funds
representing Additional Interest) may be invested in Permitted Investments in
accordance with Section 3.06. The Special Servicer shall be entitled to make
withdrawals from an REO Account to pay itself, as additional special servicing
compensation in accordance with Section 3.11(d), interest and investment income
earned in respect of amounts held in such REO Account as provided in Section
3.06(b) (but only to the extent of the Net Investment Earnings with respect to
such REO Account for any Trust Collection Period, in the case of the Pool REO
Account and the MGM Tower REO Account, or for any GIC Office Collection Period,
in the case of the GIC Office REO Account). The Special Servicer shall give
notice to the Trustee and the Master Servicer of the location of each REO
Account, and shall give notice to the related Non-Trust Mortgage Loan
Noteholder(s) of the location of any Loan Combination REO Account, in each case
when first established and of the new location of any such REO Account prior to
any change thereof.

         (c) The Special Servicer shall withdraw from the related REO Account
funds necessary for the proper operation, management, leasing, maintenance and
disposition of any REO Property, but only to the extent of amounts on deposit in
such REO Account relating to such REO Property. On the Business Day following
each Trust Determination Date, the Special Servicer shall withdraw from any Pool
REO Account and deposit into the Pool Custodial Account (or deliver to the
Master Servicer or such other Person as may be designated by the Master Servicer
for deposit into the Pool Custodial Account) the aggregate of all amounts
received in respect of each REO Property (other than any REO Property relating
to a Loan Combination) during the Trust Collection Period ending on such Trust
Determination Date, net of any withdrawals made out of such amounts pursuant to
the preceding sentence and, further, net of any reserves to be maintained in the
Pool REO Account in accordance with the last sentence of this Section 3.16(c).
On the Business Day following each GIC Office Determination Date, the Special
Servicer shall withdraw from any GIC Office REO Account and deposit into the GIC
Office Custodial Account (or deliver to the Master Servicer or such other Person
as may be designated by the Master Servicer for deposit into the GIC Office
Custodial Account) the aggregate of all amounts received in respect of any GIC
Office REO Property during the GIC Office Collection Period ending on such GIC
Office Determination Date, net of any withdrawals made out of such amounts
pursuant to the second preceding sentence and, further, net of any reserves to
be maintained in the GIC Office REO Account in accordance with the last sentence
of this Section 3.16(c). On the Business Day following each Trust Determination
Date, the Special Servicer shall withdraw from any MGM Tower REO Account and
deposit into the MGM Tower Custodial Account (or deliver to the Master Servicer
or such other Person as may be designated by the Master Servicer for deposit
into the MGM Tower Custodial Account) the aggregate of all amounts received in
respect of any MGM Tower REO Property during the Trust Collection Period ending
on such Trust Determination Date, net of any withdrawals made out of such
amounts pursuant to the third preceding sentence and, further, net of any
reserves to be maintained in the MGM Tower REO Account in accordance with the
last sentence of this Section 3.16(c). Notwithstanding the foregoing, the
Special Servicer may retain in the related REO Account such portion of proceeds
and collections in respect of any REO Property as may be necessary to maintain a
reserve of sufficient funds for the proper operation, management, leasing,
maintenance and disposition of such REO Property (including the creation of a
reasonable reserve for repairs, replacements, necessary capital replacements and
other related expenses), such reserve not to

                                     -190-
<PAGE>

exceed an amount sufficient to cover such items to be incurred during the
following twelve-month period.

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

         SECTION 3.17. Management of REO Property.

         (a) Prior to the acquisition by it of title to a Mortgaged Property,
the Special Servicer shall review the operation of such Mortgaged Property and
determine the nature of the income that would be derived from such property if
it were acquired by the Trust Fund. If the Special Servicer determines from such
review that:

                  (i) None of the income from Directly Operating such Mortgaged
         Property would be subject to tax as "net income from foreclosure
         property" within the meaning of the REMIC Provisions or would be
         subject to the tax imposed on "prohibited transactions" under Section
         860F of the Code (either such tax referred to herein as an "REO Tax"),
         then such Mortgaged Property may be Directly Operated by the Special
         Servicer as REO Property;

                  (ii) Directly Operating such Mortgaged Property as REO
         Property could result in income from such property that would be
         subject to an REO Tax, but that a lease of such property to another
         party to operate such property, or the performance of some services by
         an Independent Contractor with respect to such property, or another
         method of operating such property would not result in income subject to
         an REO Tax, then the Special Servicer may (provided that in the good
         faith and reasonable judgment of the Special Servicer, it is
         commercially reasonable) acquire such Mortgaged Property as REO
         Property and so lease or operate such REO Property; or

                  (iii) It is reasonable to believe that Directly Operating such
         property as REO Property could result in income subject to an REO Tax
         and that no commercially reasonable means exists to operate such
         property as REO Property without the Trust Fund incurring or possibly
         incurring an REO Tax on income from such property, the Special Servicer
         shall deliver to the Tax Administrator, in writing, a proposed plan
         (the "Proposed Plan") to manage such property as REO Property. Such
         plan shall include potential sources of income, and, to the extent
         reasonably possible, estimates of the amount of income from each such
         source. Upon request of the Special Servicer, the Tax Administrator
         shall advise the Special Servicer of the Tax Administrator's federal
         income tax reporting position with respect to the various sources of
         income that the Trust Fund would derive under the Proposed Plan. After
         receiving the information described in the preceding sentence from the
         Tax Administrator, the Special Servicer shall implement the Proposed
         Plan (after acquiring the respective Mortgaged Property as REO
         Property), with any amendments required to be made thereto as a result
         of the Tax Administrator's tax reporting position.

         The Special Servicer's decision as to how each REO Property shall be
managed and operated shall be based on the Servicing Standard and, further,
based on the good faith and reasonable judgment of the Special Servicer as to
which means would be in the best interest of the

                                     -191-
<PAGE>

Certificateholders (and, in the case of any GIC Office REO Property or MGM Tower
REO Property, the related Non-Trust Mortgage Loan Noteholder(s)) by maximizing
(to the extent commercially reasonable and consistent with Section 3.17(b)) the
net after-tax REO Revenues received with respect to such property without
materially impairing the Special Servicer's ability to promptly sell such
property for a fair price. In connection with performing their respective duties
under this Section 3.17(a), both the Special Servicer and the Tax Administrator
may consult with counsel and tax accountants, the reasonable cost of which
consultation shall be covered by, and be reimbursable as, a Servicing Advance to
be made by the Special Servicer.

         (b) If title to any REO Property is acquired, the Special Servicer
shall manage, conserve, protect and operate such REO Property for the benefit of
the Certificateholders (and, in the case of any GIC Office REO Property or MGM
Tower REO Property, the related Non-Trust Mortgage Loan Noteholder(s)) solely
for the purpose of its prompt disposition and sale in a manner that does not and
will not: (i) cause such REO Property to fail to qualify as "foreclosure
property" within the meaning of Section 860G(a)(8) of the Code for purposes of
Section 860D(a) of the Code; or (ii) except as contemplated by Section 3.17(a),
either result in the receipt by any REMIC Pool of any "income from non-permitted
assets" within the meaning of Section 860F(a)(2)(B) of the Code or result in an
Adverse REMIC Event or an Adverse Grantor Trust Event. Subject to the foregoing,
however, the Special Servicer shall have full power and authority to do any and
all things in connection therewith as are consistent with the Servicing Standard
and, consistent therewith, shall withdraw from the related REO Account, to the
extent of amounts on deposit therein with respect to any REO Property, funds
necessary for the proper operation, management, maintenance and disposition of
such REO Property, including:

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

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

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

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

         To the extent that amounts on deposit in the related REO Account in
respect of any REO Property are insufficient for the purposes set forth in the
preceding sentence with respect to such REO Property, the Master Servicer shall,
at the direction of the Special Servicer, make Servicing Advances in such
amounts as are necessary for such purposes unless the Master Servicer
determines, in accordance with the Servicing Standard, that such payment would
be a Nonrecoverable Advance; provided, however, that the Master Servicer may
make any such Servicing Advance without regard to recoverability if it is a
necessary fee or expense incurred in connection with the defense or prosecution
of legal proceedings.

         (c) Without limiting the generality of the foregoing, the Special
Servicer shall not, with respect to any REO Property:

                                     -192-
<PAGE>

                  (i) enter into, renew or extend any New Lease with respect to
         such REO Property, if the New Lease, by its terms would 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 such REO
         Property, other than the completion of a building or other improvement
         thereon, and then only if more than 10% 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) Directly Operate, or allow any other Person, other than
         an Independent Contractor, to Directly Operate such REO Property on any
         date more than 90 days after the related REO Acquisition;

unless, in any such case, the Special Servicer has obtained an Opinion of
Counsel (the cost of which shall be paid by the Master Servicer, at the
direction of the Special Servicer, and shall be reimbursable as a Servicing
Advance) to the effect that such action would not cause such REO Property to
fail to qualify as "foreclosure property" within the meaning of Section
860G(a)(8) of the Code for purposes of Section 860D(a) of the Code at any time
that it is held by REMIC I, in which case the Special Servicer may take such
actions as are specified in such Opinion of Counsel.

         (d) The Special 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 and shall reflect an agreement reached at arm's
         length;

                  (ii) the fees of such Independent Contractor (which shall be
         expenses of the Trust Fund and, in the case of any GIC Office REO
         Property or MGM Tower REO Property, the related Non-Trust Mortgage Loan
         Noteholder(s)) shall be reasonable and customary in consideration of
         the nature and locality of such REO Property;

                  (iii) except as permitted under Section 3.17(a), any such
         contract shall require, or shall be administered to require, that the
         Independent Contractor, in a timely manner, (A) pay out of related REO
         Revenues all costs and expenses incurred in connection with the
         operation and management of such REO Property, including those listed
         in Section 3.17(b) above, and (B) except to the extent that such
         revenues are derived from any services rendered by the Independent
         Contractor to tenants of such REO Property that are not customarily
         furnished or rendered in connection with the rental of real property
         (within the meaning of Section 1.856-4(b)(5) of the Treasury
         regulations or any successor provision), remit all related revenues
         collected (net of its fees and such costs and expenses) to the Special
         Servicer upon receipt;

                  (iv) none of the provisions of this Section 3.17(d) relating
         to any such contract or to actions taken through any such Independent
         Contractor shall be deemed to relieve

                                     -193-
<PAGE>

         the Special Servicer of any of its duties and obligations hereunder
         with respect to the operation and management of such REO Property; and

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

         The Special Servicer shall be entitled to enter into any agreement with
any Independent Contractor performing services for it related to its duties and
obligations under Section 3.16 and this Section 3.17 for indemnification of the
Special Servicer by any such Independent Contractor, and nothing in this
Agreement shall be deemed to limit or modify such indemnification. No agreement
entered into pursuant to this Section 3.17(d) shall be deemed a Sub-Servicing
Agreement for purposes of Section 3.22.

         SECTION 3.18. Sale of Trust Mortgage Loans and REO Properties.

         (a) The Master Servicer, the Special Servicer or the Trustee may sell
or purchase, or permit the sale or purchase of, a Trust Mortgage Loan or REO
Property only (i) on the terms and subject to the conditions set forth in this
Section 3.18, (ii) as otherwise expressly provided in or contemplated by
Sections 2.03 and 9.01 of this Agreement and/or the UBS/Depositor Mortgage Loan
Purchase Agreement, (iii) in the case of the MGM Tower Trust Mortgage Loan, as
set forth in the MGM Tower Co-Lender Agreement, (iv) in the case of the GIC
Office Trust Mortgage Loan, as set forth in the GIC Office Co-Lender Agreement,
and (v) in the case of a Trust Mortgage Loan with a related mezzanine loan, in
connection with a Mortgage Loan default as set forth in the related
intercreditor agreement.

         (b) Within five (5) Business Days after any Trust Mortgage Loan has
become a Specially Serviced Trust Mortgage Loan, the Special Servicer shall give
notice of such event to the related Non-Trust Mortgage Loan Noteholder(s) (if
such Trust Mortgage Loan is part of a Loan Combination), each holder of a
Certificate of the Controlling Class and the Trustee. The Special Servicer, any
single Holder or any group of Certificateholders evidencing a majority of the
Voting Rights allocated to the Controlling Class and any assignees of the
foregoing parties (collectively, the "Purchase Option Holders") shall each have
the option to purchase such Specially Serviced Trust Mortgage Loan at a cash
price that is at least equal to the Purchase Price; provided that a material
default exists with respect to such Specially Serviced Trust Mortgage Loan; and
provided further, that any such purchase by a Purchase Option Holder of the GIC
Office Trust Mortgage Loan shall be subject to the simultaneous cash purchase by
such Purchase Option Holder of each GIC Office Pari Passu Non-Trust Mortgage
Loan at the related GIC Office Pari Passu Non-Trust Mortgage Loan Purchase
Price, which simultaneous purchase shall be on the same terms and conditions as
are set forth herein for any such purchase of the GIC Office Trust Mortgage
Loan. The Special Servicer shall accept the first offer by a Purchase Option
Holder that is at least equal to the Purchase Price (plus, if the GIC Office
Pari Passu Non-Trust Mortgage Loans are to be purchased, the respective GIC
Office Pari Passu Non-Trust Mortgage Loan Purchase Prices).

         (c) If none of the Purchase Option Holders exercises its option to
purchase any Specially Serviced Trust Mortgage Loan as described in subsection
(b) above, then each Purchase Option Holder will also have the option to
purchase that Specially Serviced Trust Mortgage Loan at a price equal to the
fair value (the "FV Price") of such Specially Serviced Trust Mortgage Loan;
provided that a material default exists with respect to such Specially Serviced
Trust Mortgage Loan; and provided

                                     -194-
<PAGE>

further, that any purchase by a Purchase Option Holder of the GIC Office Trust
Mortgage Loan at the FV Price shall be subject to the simultaneous cash purchase
by such Purchase Option Holder of each GIC Office Pari Passu Non-Mortgage Trust
Loan at a FV Price to be determined by the Special Servicer in the same manner
that the FV Price is determined by the Special Servicer with respect to the GIC
Office Trust Mortgage Loan, which simultaneous purchase shall be on the terms
and conditions as are set forth herein for any such purchase of the GIC Office
Trust Mortgage Loan. Upon receipt of a request from any Purchase Option Holder
to determine the FV Price in contemplation of its intention to exercise its
option to purchase a Specially Serviced Trust Mortgage Loan at a price that is
below the Purchase Price, the Special Servicer shall promptly obtain an MAI
appraisal of the related Mortgaged Property by an Independent Appraiser (unless
such an appraisal was obtained within one year of such date and the Special
Servicer has no knowledge of any circumstances that would materially affect the
validity of such appraisal). Promptly after obtaining such appraisal, the
Special Servicer shall determine the FV Price for the subject Specially Serviced
Trust Mortgage Loan (and, if applicable, for each GIC Office Pari Passu
Non-Trust Mortgage Loan) in accordance with the Servicing Standard and the
provisions of subsection (i) below. Promptly after determining such FV Price(s),
the Special Servicer shall report such FV Price(s) to the Trustee and each
Purchase Option Holder.

         (d) In the event that the Special Servicer determines that it is
willing, or another Purchase Option Holder notifies the Special Servicer that it
is willing, to purchase any Specially Serviced Trust Mortgage Loan (the party
submitting such bid, the "Initial Bidder") at a price equal to or above the FV
Price (a "FV Bid"), the Special Servicer shall notify all other Purchase Option
Holders that it has made or received, as the case may be, such FV Bid (without
disclosing the amount of such FV Bid). All other Purchase Option Holders may
submit competing bids within the ten (10) Business Day period following such
notice. At the conclusion of the above-described ten (10) Business Day period,
the Special Servicer shall accept the highest bid received from any Purchase
Option Holder that is at least equal to the FV Price for the subject Specially
Serviced Mortgage Loan. If the GIC Office Trust Mortgage Loan is to be purchased
in accordance with the foregoing process at a price above its FV Price, then the
price at which each of the GIC Office Pari Passu Non-Trust Mortgage Loans is to
be purchased will be increased in the same proportion.

         (e) If the Special Servicer accepts the bid of any Purchase Option
Holder, such Purchase Option Holder shall be required to purchase the subject
Specially Serviced Trust Mortgage Loan (together with, in the case of the GIC
Office Trust Mortgage Loan, the five GIC Office Pari Passu Non-Trust Mortgage
Loans) within ten (10) Business Days of receipt of notice of such acceptance.

         (f) If the Special Servicer has not accepted a FV Bid prior to the
expiration of 120 days from its determination of the FV Price and thereafter
receives a FV Bid or a request from a Purchase Option Holder for an updated FV
Price, the Special Servicer shall within 45 days recalculate the FV Price (with
no presumption that such FV Price should be reduced on account of the lack of an
FV Bid) and repeat the notice and bidding procedure provided in subsection (d)
above until the purchase option terminates under subsection (j) below.

         (g) If the party exercising the purchase option at the FV Price for any
Specially Serviced Trust Mortgage Loan is the Special Servicer or an Affiliate
thereof, the Trustee shall verify that the FV Price of such Trust Mortgage Loan
(and, in the case of the GIC Office Trust Mortgage Loan, the FV Price of each
GIC Office Pari Passu Non-Trust Mortgage Loan) is at least equal to the fair
value of such Trust Mortgage Loan. In determining whether the FV Price of any
Specially Serviced Trust

                                     -195-
<PAGE>

Mortgage Loan (and, in the case of the GIC Office Trust Mortgage Loan, the FV
Price of each GIC Office Pari Passu Non-Trust Mortgage Loan) is at least equal
to the fair value of such Mortgage Loan, the Trustee will be permitted to
conclusively rely on an appraisal obtained by the Trustee from an Independent
Appraiser at the time it is required to verify such FV Price(s) and/or the
opinion of an Independent expert in real estate matters (including the Master
Servicer) with at least five years' experience in valuing or investing in loans,
similar to the subject Specially Serviced Trust Mortgage Loan, that has been
selected by the Trustee with reasonable care at the expense of the Trust Fund.

         (h) Any Purchase Option Holder may, once such option is exercisable,
assign its purchase option with respect to any Specially Serviced Trust Mortgage
Loan (and, in the case of the GIC Office Trust Mortgage Loan, each GIC Office
Pari Passu Non-Trust Mortgage Loan) to a third party other than another Purchase
Option Holder; and, upon such assignment such third party shall have all of the
rights that had been granted to the Purchase Option Holder hereunder in respect
of the purchase option. Such assignment shall only be effective upon written
notice (together with a copy of the executed assignment and assumption
agreement) being delivered to the Trustee, the Master Servicer and the Special
Servicer.

         (i) In determining the FV Price for any Specially Serviced Mortgage
Loan under this Section 3.18, the Special Servicer may take into account, among
other factors, the results of any appraisal or updated appraisal that it or the
Master Servicer may have obtained in accordance with this Agreement within the
prior twelve months; the opinions on fair value expressed by Independent
investors in mortgage loans comparable to the subject Specially Serviced
Mortgage Loan; the period and amount of any delinquency on the subject Specially
Serviced Mortgage Loan; the physical condition of the related Mortgaged
Property; the state of the local economy; and the expected recoveries from the
subject Specially Serviced Mortgage Loan if the Special Servicer were to pursue
a workout or foreclosure strategy instead of selling such Mortgage Loan to a
Purchase Option Holder.

         (j) The purchase option for any Specially Serviced Mortgage Loan
pursuant to this Section 3.18 shall terminate, and shall not be exercisable as
set forth in subsections (b) and (c) above (or if exercised, but the purchase of
such Specially Serviced Mortgage Loan has not yet occurred, shall terminate and
be of no further force or effect) if and when (i) the Special Servicer has
accepted a FV Bid, (ii) such Specially Serviced Mortgage Loan has become a
Corrected Mortgage Loan, (iii) the related Mortgaged Property has become an REO
Property, (iv) a Final Recovery Determination has been made with respect to such
Specially Serviced Mortgage Loan or (v) the subject Specially Serviced Trust
Mortgage Loan has been removed from the Trust Fund.

         (k) Until such time as a FV Bid is accepted with respect to any
Specially Serviced Trust Mortgage Loan, the Special Servicer shall continue to
pursue all of the other resolution options available to it with respect to such
Specially Serviced Trust Mortgage Loan (and, in the case of the GIC Office Trust
Mortgage Loan, each GIC Office Pari Passu Non-Trust Mortgage Loan in accordance
with the Servicing Standard.

         (l) Notwithstanding anything to the contrary herein, in accordance with
the GIC Office Co-Lender Agreement, the GIC Office Subordinate Non-Trust
Mortgage Loan Noteholder will be entitled to purchase the GIC Office Trust
Mortgage Loan in accordance with the terms and conditions set forth in the GIC
Office Co-Lender Agreement, even after it has been purchased out of the Trust
Fund pursuant to the purchase option provided for in this Section 3.18. In
connection with any such purchase,

                                     -196-
<PAGE>

the Master Servicer or the Special Servicer, as applicable, shall determine the
price to be paid therefor and shall provide such notices to the GIC Office
Subordinate Non-Trust Mortgage Loan Noteholder as are required by the GIC Office
Co-Lender Agreement with respect to such holder's purchase rights.

         (m) Notwithstanding anything to the contrary herein, the MGM Tower
Non-Trust Mortgage Loan Noteholder shall be entitled to purchase the MGM Tower
Trust Mortgage Loan in accordance with the terms and conditions set forth in the
MGM Tower Co-Lender Agreement, even after it has been purchased out of the Trust
Fund pursuant to the purchase option provided for in this Section 3.18. The
Master Servicer or the Special Servicer, as applicable, shall determine the
price to be paid in accordance with the terms of the MGM Tower Co-Lender
Agreement in connection with any such purchase and shall provide such notices to
the MGM Tower Non-Trust Mortgage Loan Noteholder as are required by the MGM
Tower Co-Lender Agreement in connection with such holder's purchase rights.

         (n) Any purchase of a Specially Serviced Mortgage Loan that is
purchased pursuant to the purchase option provided for in this Section 3.18 will
remain subject to the cure and purchase rights, in each case if applicable, of
any holder of a related mezzanine loan in connection with a Mortgage Loan
default as set forth in the related intercreditor agreement.

         (o) The Special Servicer shall use its best efforts to solicit bids for
each REO Property in such manner as will be reasonably likely to realize a fair
price within the time period provided for by Section 3.16(a). Subject to
Sections 6.11, 6.12, and/or 6.13, if and as applicable, the Special Servicer
shall accept the first (and, if multiple bids are received contemporaneously or
subsequently, the highest) cash bid received from any Person that constitutes a
fair price for such REO Property. If the Special Servicer reasonably believes
that it will be unable to realize a fair price for any REO Property within the
time constraints imposed by Section 3.16(a), then (subject to Sections 6.11,
6.12, and/or 6.13, if and as applicable) the Special Servicer shall dispose of
such REO Property upon such terms and conditions as the Special Servicer shall
deem necessary and desirable to maximize the recovery thereon under the
circumstances and, in connection therewith, shall accept the highest outstanding
cash bid, regardless of from whom received.

         (p) The Special Servicer shall give the Trustee and the Depositor prior
written notice of its intention to sell any REO Property pursuant to this
Section 3.18.

         (q) No Interested Person shall be obligated to submit a bid to purchase
any REO Property, and notwithstanding anything to the contrary herein, neither
the Trustee, in its individual capacity, nor any of its Affiliates may bid for
or purchase any REO Property pursuant hereto.

         (r) Whether any cash bid constitutes a fair price for any REO Property
for purposes of this Section 3.18, shall be determined by the Special Servicer
or, if such cash bid is from the Special Servicer or an Affiliate of the Special
Servicer, by the Trustee. In determining whether any bid received from the
Special Servicer or an Affiliate of the Special Servicer represents a fair price
for any REO Property, the Trustee shall be supplied with and shall be entitled
to rely on the most recent appraisal in the related Servicing File conducted in
accordance with this Agreement within the preceding 12-month period (or, in the
absence of any such appraisal or if there has been a material change at the
subject REO Property since any such appraisal, on a new appraisal to be obtained
by the Special Servicer (the cost of which shall be covered by, and be
reimbursable as, a Servicing Advance)). The appraiser conducting any such new
appraisal shall be an Independent Appraiser selected by the Special Servicer if
neither the

                                     -197-
<PAGE>

Special Servicer nor any Affiliate thereof is bidding with respect to an REO
Property and selected by the Trustee if either the Special Servicer or any
Affiliate thereof is so bidding. Where any Interested Person is among those
bidding with respect to an REO Property, the Special Servicer shall require that
all bids be submitted to it (and, if the Special Servicer or any Affiliate
thereof is bidding, to the Trustee) in writing and be accompanied by a
refundable deposit of cash in an amount equal to 5% of the bid amount. In
determining whether any bid from a Person other than itself or one of its
Affiliates constitutes a fair price for any REO Property, the Special Servicer
shall take into account the results of any appraisal or updated appraisal that
it or the Master Servicer may have obtained in accordance with this Agreement
within the prior twelve months, and any Independent Appraiser shall be
instructed to take into account, as applicable, among other factors, the
occupancy level and physical condition of the subject REO Property, the state of
the local economy and the obligation to dispose of the subject REO Property
within the time period specified in Section 3.16(a). The Purchase Price for any
REO Property shall in all cases be deemed a fair price. Notwithstanding the
other provisions of this Section 3.18, no cash bid from the Special Servicer or
any Affiliate thereof shall constitute a fair price for any REO Property unless
such bid is the highest cash bid received and at least two independent bids (not
including the bid of the Special Servicer or any Affiliate) have been received.
In the event the bid of the Special Servicer or any Affiliate thereof is the
only bid received or is the higher of only two bids received, then additional
bids shall be solicited. If an additional bid or bids, as the case may be, are
received and the original bid of the Special Servicer or any Affiliate thereof
is the highest of all cash bids received, then the bid of the Special Servicer
or such Affiliate shall be accepted, provided that the Trustee has otherwise
determined, as provided above in this Section 3.18(s), that such bid constitutes
a fair price for any REO Property. Any bid by the Special Servicer shall be
unconditional; and, if accepted, the subject REO Property shall be transferred
to the Special Servicer without recourse, representation or warranty other than
customary representations as to title given in connection with the sale of a
real property.

         (s) Subject to Sections 3.18(a) through 3.18(r) above, and further
subject to Section 6.11, Section 6.12, and/or Section 6.13, in each case if and
as applicable, the Special Servicer shall act on behalf of the Trustee in
negotiating with independent third parties seeking to purchase an REO Property
and taking any other action necessary or appropriate in connection with the sale
of any Specially Serviced Trust Mortgage Loan or REO Property pursuant to this
Section 3.18, and the collection of all amounts payable in connection therewith.
In connection therewith, the Special Servicer may charge prospective bidders for
any REO Property, and may retain, fees that approximate the Special Servicer's
actual costs in the preparation and delivery of information pertaining to, or
evaluating bids for, such REO Property without obligation to deposit such
amounts into any Custodial Account. Any sale of a Specially Serviced Trust
Mortgage Loan or an REO Property pursuant to this Section 3.18 shall be final
and without recourse to the Trustee or the Trust, and if such sale is
consummated in accordance with the terms of this Agreement, neither the Special
Servicer nor the Trustee shall have any liability to any Certificateholder with
respect to the purchase price therefor accepted by the Special Servicer or the
Trustee.

         (t) Any sale of a Specially Serviced Trust Mortgage Loan or an REO
Property pursuant to this Section 3.18 shall be for cash only and shall be on a
servicing released basis.

         SECTION 3.19. Additional Obligations of the Master Servicer;
                       Obligations to Notify Ground Lessors and Hospitality
                       Franchisors; the Special Servicer's Right to Request
                       the Master Servicer to Make Servicing Advances.

         (a) The Master Servicer shall deliver to the Trustee for deposit in the
Collection Account on each Trust Master Servicer Remittance Date, without any
right of reimbursement therefor, an amount equal to the lesser of (i) the
aggregate amount of all Prepayment Interest Shortfalls, if any, incurred in
connection with Principal Prepayments received during the most recently ended
applicable Collection Period, with respect to Performing Trust Mortgage Loans
and (ii) the sum of (1) the aggregate of all Master Servicing Fees received by
the Master Servicer during such Collection Period with respect to the entire
Mortgage Pool (but only to the extent of that portion thereof calculated at a
rate of 0.015% per annum with respect to each and every Trust Mortgage Loan and
REO Trust Mortgage Loan) and (2) the aggregate amount of Prepayment Interest
Excesses received in respect of the entire Mortgage Pool during such Collection
Period; provided, however, that if any Prepayment Interest Shortfall occurs with
respect to any Trust Mortgage Loan as a result of the Master Servicer's allowing
the Mortgagor to deviate from the terms of the related loan documents regarding
principal prepayments, the Master Servicer shall be obligated to pay an amount
equal to the entire Prepayment Interest Shortfall with respect to the subject
Trust Mortgage Loan without any limitation of the kind set forth in clauses (1)
and (2) above.

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

         (c) The Master Servicer shall, as to each Trust Mortgage Loan which is
secured by the interest of the related Mortgagor in a hospitality property, not
later than the later of (i) 30 days following the Master Servicer's receipt of
the subject franchise agreement and (ii) the expiration of the period that may
be required for such notice pursuant to the terms of the applicable franchise
documents, if any, notify the related hospitality franchisor of the transfer of
such Trust Mortgage Loan to the Trust Fund pursuant to this Agreement and inform
such hospitality franchisor that any notices of default under the related
franchise agreement should thereafter be forwarded to the Master Servicer.

         (d) Notwithstanding anything to the contrary contained in this
Agreement, if the Special Servicer is required under this Agreement to make any
Servicing Advance but does not desire to do so, the Special Servicer may, in its
sole discretion, request that the Master Servicer make such Servicing Advance,
such request to be made, in writing, at least five (5) Business Days (or, in an
emergency situation or on an urgent basis, two (2) Business Days, provided that
the written request sets forth the nature of the emergency or the basis of the
urgency) in advance of the date on which such Servicing Advance is required to
be made hereunder and to be accompanied by such information and documentation
regarding the subject Servicing Advance as the Master Servicer may reasonably
request. The Master Servicer shall have the obligation to make any such
Servicing Advance that it is so requested by the Special Servicer to make,
within five (5) Business Days (or, in an emergency situation or on an urgent
basis, two (2) Business Days) of the Master Servicer's receipt of such request.
If the

                                     -199-
<PAGE>

request is timely and properly made, the Special Servicer shall be relieved of
any obligations with respect to a Servicing Advance that it so requests the
Master Servicer to make (regardless of whether or not the Master Servicer shall
make such Servicing Advance). The Master Servicer shall be entitled to
reimbursement for any Servicing Advance made by it at the direction of the
Special Servicer, together with interest thereon in accordance with Sections
3.05(a), 3.05A, 3.05B and/or 3.11(g), as applicable, at the same time, in the
same manner and to the same extent as the Master Servicer is entitled with
respect to any other Servicing Advances made thereby.

         Notwithstanding the foregoing provisions of this Section 3.19(d), the
Master Servicer shall not be required to make at the direction of the Special
Servicer, any Servicing Advance if the Master Servicer determines in its
reasonable, good faith judgment that such Servicing Advance, although not
characterized by the Special Servicer as a Nonrecoverable Servicing Advance, is
in fact a Nonrecoverable Servicing Advance. The Master Servicer shall notify the
Special Servicer in writing of such determination, which shall be made pursuant
to Section 3.11(h). Any request by the Special Servicer that the Master Servicer
make a Servicing Advance shall be deemed to be a determination by the Special
Servicer that such requested Servicing Advance is not a Nonrecoverable Servicing
Advance, and the Master Servicer, the Trustee and the Fiscal Agent shall be
entitled to conclusively rely on such determination. Upon making a
determination, pursuant to Section 3.11(h), that any Servicing Advance
previously made or proposed to be made with respect to a Specially Serviced
Mortgage Loan or an REO Property is a Nonrecoverable Servicing Advance, the
Special Servicer shall report to the Master Servicer and the Trustee the Special
Servicer's determination. The Master Servicer shall be entitled to conclusively
rely on such a determination by the Special Servicer.

         (e) The Master Servicer and the Special Servicer shall each be
responsible for providing: (i) to the MGM Tower Non-Trust Mortgage Loan
Noteholder such notices regarding defaults and events of default under the MGM
Tower Loan Pair as are required from the Trust, as holder of the MGM Tower Trust
Mortgage Loan, by the second paragraph of Section 7.01 of the MGM Tower
Co-Lender Agreement; (ii) to the GIC Office Subordinate Non-Trust Mortgage Loan
Noteholder such notices regarding defaults and events of default under the GIC
Office Loan Group as are required from the Trust, as holder of the GIC Office
Trust Mortgage Loan, by the second paragraph of Section 7.01 of the GIC Office
Co-Lender Agreement; (iii) to the GIC Office Subordinate Non-Trust Mortgage Loan
Noteholder copies of any notices received from the "Mezzanine Lender" (within
the meaning of the GIC Office Co-Lender Agreement) that such lender intends to
exercise its cure rights with respect to the GIC Office Loan Group, as required
from the "Lead Lender" (within the meaning of the GIC Office Co-Lender
Agreement) by Section 6.13(c) of the GIC Office Co-Lender Agreement; and (iv) to
any lender of related mezzanine debt as may be required from the Trust, as
holder of a Trust Mortgage Loan, under any related co-lender, intercreditor or
similar agreement.

         SECTION 3.20. Modifications, Waivers, Amendments and Consents;
                       Defeasance.

         (a) Subject to Sections 3.20(b) through 3.20(f) and 3.20(l) below, and
further subject to Section 6.11, Section 6.12, and/or Section 6.13, in each case
if and as applicable, and any related intercreditor, co-lender or similar
agreement (including, in the case of a Mortgage Loan in Loan Combination, the
related Co-Lender Agreement), the Special Servicer (or, under the limited
circumstances set forth in Section 3.20(c), the Master Servicer) may, on behalf
of the Trustee and, in the case of a Non-Trust Mortgage Loan, the related
Non-Trust Mortgage Loan Noteholder, agree to any modification, extension, waiver
or amendment of any term of any Mortgage Loan and respond to

                                     -200-
<PAGE>

various Mortgagor requests for consent on the part of the mortgagee (including
the lease reviews and lease consents related thereto), without the consent of
the Trustee, any Certificateholder, any Non-Trust Mortgage Loan Noteholder, the
Master Servicer (in the case of any such action taken by the Special Servicer)
or, except as expressly set forth below, the Special Servicer (in the case of
any such action taken by the Master Servicer).

         (b) All modifications, extensions, waivers or amendments of any
Mortgage Loan, including the lease reviews and lease consents related thereto,
shall be in writing and shall be considered and effected in a manner consistent
with the Servicing Standard.

         (c) In the case of any Performing Mortgage Loan, and subject to the
rights of the Special Servicer set forth below, the Master Servicer shall be
responsible for responding to any request by a Mortgagor for the consent or
approval of the mortgagee with respect to a modification, extension, waiver or
amendment of any term thereof, provided that such consent or approval or such
modification, extension, waiver or amendment would not (except as permitted by
Sections 3.02(a), 3.03(d), 3.07, 3.08(a) and 3.20(l) and the next paragraph of
this Section 3.20(c)) affect the amount or timing of any of the payment terms of
such Mortgage Loan (including payment terms related to late payment charges),
result in the release of the related Mortgagor from any material term
thereunder, waive any rights thereunder with respect to any guarantor thereof,
relate to the release, addition or substitution of any material collateral for
such Mortgage Loan or relate to any waiver of or granting of consent under a
"due-on-sale" or "due-on-encumbrance" clause. With respect to any action
proposed to be taken by the Master Servicer under this Section 3.20(c) where the
thresholds in clauses (i) through (vi) of the next sentence are exceeded, or
which involves the situations set forth in the proviso to the previous sentence,
the Special Servicer only may take such action. To the extent consistent with
the foregoing, but subject to Section 3.20(f), the Master Servicer shall also be
responsible for the following with respect to each Performing Mortgage Loan:

                  (i) Approving any waiver affecting the timing of receipt of
         financial statements from any Mortgagor, provided that such financial
         statements are delivered no less than quarterly and within 60 days of
         the end of the calendar quarter to which such financial statements
         relate;

                  (ii) Approving routine leasing activity with respect to leases
         for less than the lesser of (A) 50,000 square feet and (B) 20% of the

                  (iii) Approving a transfer of equity in a Mortgagor from one
         current equity holder to another, provided that such transfer of equity
         does not (A) affect (if applicable) the status of such Mortgagor or
         such equity holder as a special purpose, bankruptcy-remote entity, (B)
         result in a change of control of such Mortgagor, (C) cause the
         transferee to hold more than 49% of the equity in such Mortgagor, (D)
         relate to a Trust Mortgage Loan that represents 2% or more of the then
         aggregate principal balance of the Mortgage Pool or (E) relate to a
         Loan Combination;

                  (iv) Approving annual budgets for the related Mortgaged
         Property, provided that no such budget (A) relates to a fiscal year in
         which an Anticipated Repayment Date occurs, (B) provides for the
         payment of operating expenses in an amount equal to more than 110% of
         the amounts budgeted therefor for the prior year or (C) provides for
         the payment of any material expenses to any affiliate of the Mortgagor
         (other than with respect to the payment of the

                                     -201-
<PAGE>

         management fee to any property manager if such management fee is no
         more than the management fee in effect on the Cut-off Date);

                  (v) Approving easements or rights of way that do not
         materially affect the use or value of a Mortgaged Property or the
         Mortgagor's ability to make any payments with respect to the subject
         Performing Mortgage Loan; and

                  (vi) Approving a change of the property manager at the request
         of the related Mortgagor, provided that (A) the successor property
         manager is not affiliated with the Mortgagor and is a nationally or
         regionally recognized manager of similar properties, (B) the related
         Trust Mortgage Loan does not represent 2% or more of the then aggregate
         principal balance of the Mortgage Pool and (C) the subject Mortgaged
         Property does not secure a Loan Combination.

         Subject to Section 6.11, Section 6.12 or Section 6.13, as applicable,
and the Servicing Standard, and further subject to the second sentence of the
next paragraph and the second paragraph of Section 3.20(e), the Master Servicer
may, upon the occurrence of a potential default in the making of a Balloon
Payment on a Performing Five-Year Mortgage Loan, extend the maturity date of
such Performing Five-Year Mortgage Loan for up to six months; provided that the
Master Servicer may only approve two such six-month extensions of the maturity
date of any Performing Five-Year Mortgage Loan.

         Except as permitted by Section 3.02(a), Section 3.03(d), Section 3.07,
Section 3.08(a), this Section 3.20(c) and Section 3.20(l), the Master Servicer
may not agree to waive, modify or amend any term of any Mortgage Loan or respond
to any Mortgagor requests for mortgagee consent. Furthermore, the Master
Servicer may not agree to any modification, extension, waiver or amendment of
any term of any Mortgage Loan that would cause an Adverse REMIC Event with
respect to any REMIC Pool or an Adverse Grantor Trust Event with respect to the
Grantor Trust.

         (d) Except as provided in Section 3.02(a), Section 3.07, Section 3.08,
Section 3.20(e) or Section 3.20(l), the Special Servicer, on behalf of the
Trustee or, in the case of a Non-Trust Mortgage Loan, the related Non-Trust
Mortgage Loan Noteholder, shall not agree or consent to any modification,
extension, waiver or amendment of any term of any Mortgage Loan that would:

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

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

                  (iii) except as expressly contemplated by the related Mortgage
         or pursuant to Section 3.09(d), result in a release of the lien of the
         Mortgage on any material portion of the related Mortgaged Property
         without a corresponding Principal Prepayment in an amount not less than
         the fair market value (as determined by an appraisal by an Independent
         Appraiser delivered

                                     -202-
<PAGE>

         to the Special Servicer at the expense of the related Mortgagor and
         upon which the Special Servicer may conclusively rely) of the property
         to be released; or

                  (iv) in the reasonable, good faith judgment of the Special
         Servicer, otherwise materially impair the security for such Mortgage
         Loan or reduce the likelihood of timely payment of amounts due thereon.

         (e) Notwithstanding Section 3.20(d), but subject to Section 6.11,
Section 6.12 and/or Section 6.13, in each case if and as applicable, and the
second and third paragraphs of this Section 3.20(e), the Special Servicer may
(i) reduce the amounts owing under any Specially Serviced Mortgage Loan by
forgiving principal, accrued interest (including Additional Interest) or any
Prepayment Premium or Yield Maintenance Charge, (ii) reduce the amount of the
Monthly Payment on any Specially Serviced Mortgage Loan, including by way of a
reduction in the related Mortgage Rate, (iii) forbear in the enforcement of any
right granted under any Mortgage Note, Mortgage or other loan document relating
to a Specially Serviced Mortgage Loan, (iv) accept a Principal Prepayment on any
Specially Serviced Mortgage Loan during any Lockout Period, or (v) extend the
maturity of any Specially Serviced Mortgage Loan; provided that (A) the related
Mortgagor is in monetary default or material non-monetary default with respect
to such Specially Serviced Mortgage Loan or, in the reasonable, good faith
judgment of the Special Servicer, such default is reasonably foreseeable, (B) in
the reasonable, good faith judgment of the Special Servicer, such modification,
extension, waiver or amendment would increase the recovery on such Specially
Serviced Mortgage Loan to Certificateholders (as a collective whole) or, if a
Loan Combination is involved, would increase the recovery on such Loan
Combination to Certificateholders and the related Non-Trust Mortgage Loan
Noteholder(s) (as a collective whole), on a present value basis (the relevant
discounting of anticipated collections that will be distributable to the
Certificateholders (or, in the case of a Loan Combination, to Certificateholders
and the related Non-Trust Mortgage Loan Noteholder(s)), to be performed at the
related Mortgage Rate(s)), and (C) such modification, extension, waiver or
amendment would not cause an Adverse REMIC Event in respect of any REMIC Pool or
an Adverse Grantor Trust Event with respect to the Grantor Trust; and provided,
further, that (S) any modification, extension, waiver or amendment of the
payment terms of the MGM Tower Loan Pair shall be structured so as to be
consistent with the allocation and payment priorities set forth in the related
loan documents and the MGM Tower Co-Lender Agreement, such that neither the
Trust as holder of the MGM Tower Trust Mortgage Loan nor the MGM Tower Non-Trust
Mortgage Loan Noteholder shall gain a priority over the other such holder with
respect to any payment, which priority is not, as of the date of the MGM Tower
Co-Lender Agreement, reflected in the related loan documents and such co-lender
agreement, and (T) to the extent consistent with the Servicing Standard (taking
into account the extent to which the MGM Tower Non-Trust Mortgage Loan is junior
to the MGM Tower Trust Mortgage Loan), (1) no waiver, reduction or deferral of
any particular amounts due on the MGM Tower Trust Mortgage Loan shall be
effected prior to the waiver, reduction or deferral of the entire corresponding
item in respect of the MGM Tower Non-Trust Mortgage Loan, and (2) no reduction
of the Mortgage Rate of the MGM Tower Trust Mortgage Loan shall be effected
prior to the reduction of the Mortgage Rate of the MGM Tower Non-Trust Mortgage
Loan, to the fullest extent possible; and provided, further, that (X) any
modification, extension, waiver or amendment of the payment terms of the GIC
Office Loan Group shall be structured so as to be consistent with the allocation
and payment priorities set forth in the related loan documents and the GIC
Office Co-Lender Agreement, such that neither the Trust as holder of the GIC
Office Trust Mortgage Loan nor any of the GIC Office Non-Trust Mortgage Loan
Noteholders shall gain a priority over any other such holder with respect to any
payment, which priority is not, as of the date of the GIC

                                     -203-
<PAGE>

Office Co-Lender Agreement, reflected in the related loan documents and the GIC
Office Co-Lender Agreement, and (Y) to the extent consistent with the Servicing
Standard (taking into account the extent to which the GIC Office Subordinate
Non-Trust Mortgage Loan is junior to the GIC Office Note A Mortgage Loans), (1)
no waiver, reduction or deferral of any particular amounts due on any of the GIC
Office Note A Mortgage Loans shall be effected prior to the waiver, reduction or
deferral of the entire corresponding item in respect of the GIC Office
Subordinate Non-Trust Mortgage Loan, and (2) no reduction of the Mortgage Rate
of any of the GIC Office Note A Mortgage Loans shall be effected prior to the
reduction of the Mortgage Rate of the GIC Office Subordinate Non-Trust Mortgage
Loan, to the fullest extent possible; and provided, further, that any of the
actions referred to in subclauses (1) and (2) of the foregoing proviso shall be
effected, as among the GIC Office Note A Mortgage Loans, without regard to or
any effect on the defeased portions thereof, on a pro rata and pari passu basis
(in accordance with the GIC Office Co-Lender Agreement).

         In no event shall the Special Servicer or the Master Servicer: (i)
extend the maturity date of a Mortgage Loan beyond the date that is two years
prior to the last Rated Final Distribution Date; (ii) extend the maturity date
of any Mortgage Loan for more than five years beyond its Stated Maturity Date;
or (iii) if the subject Mortgage Loan is secured solely or primarily by a
Mortgage on the leasehold interest under a Ground Lease (but not the related fee
interest), extend the maturity date of such Mortgage Loan beyond the date which
is 20 years (or, to the extent consistent with the Servicing Standard, giving
due consideration to the remaining term of the Ground Lease, 10 years) prior to
the expiration of the term of such Ground Lease.

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

         (f) Notwithstanding anything to the contrary in this Agreement, none of
the Trustee, the Master Servicer or the Special Servicer, as applicable, shall
give any consent, approval or direction regarding the termination of the related
property manager or the designation of any replacement property manager or, if
such Mortgaged Property is hospitality property, give any consent, approval or
direction regarding the termination of the franchise or the designation of a new
franchise, with respect to any Mortgaged Property that secures either the GIC
Office Loan Group or a Trust Mortgage Loan that has an unpaid principal balance
that is at least equal to the lesser of $20,000,000 and 2% of the then aggregate
principal balance of the Mortgage Pool, unless: (1) the mortgagee is not given
discretion under the terms of the related Mortgage Loan to withhold its consent;
or (2) it has received prior written confirmation from each Rating Agency that
such action will not result in an Adverse Rating Event with respect to any Class
of Certificates or any class of GIC Office Pari Passu Non-Trust Mortgage Loan
Securities rated by such Rating Agency.

         Any party hereto seeking Rating Agency confirmation with respect to the
matters described above shall deliver a Review Package to such Rating Agency.

                                     -204-
<PAGE>

         (g) Any payment of interest that is deferred pursuant to any
modification, extension, waiver or amendment permitted hereunder, shall not, for
purposes hereof, including calculating monthly distributions to
Certificateholders, be added to the unpaid principal balance or Stated Principal
Balance of the related Mortgage Loan, notwithstanding that the terms of such
modification, extension, waiver or amendment so permit. The foregoing shall in
no way limit the Special Servicer's ability to charge and collect from the
Mortgagor costs otherwise collectible under the terms of the related Mortgage
Note.

         (h) The Special Servicer or Master Servicer may, as a condition to
granting any request by a Mortgagor for consent, modification, extension, waiver
or indulgence or any other matter or thing, the granting of which is within its
discretion pursuant to the terms of the instruments evidencing or securing the
related Mortgage Loan and, further, by the terms of this Agreement and
applicable law, require that such Mortgagor pay to it (i) as additional
servicing compensation, a reasonable or customary fee for the additional
services performed in connection with such request, and (ii) any related costs
and expenses incurred by it. Any such fee that is to be shared by the Master
Servicer and the Special Servicer may not be waived or reduced by either such
party without the consent of the other party. In no event shall the Special
Servicer or Master Servicer be entitled to payment for such fees or expenses
unless such payment is collected from the related Mortgagor.

         (i) The Special Servicer and Master Servicer shall each notify the
other, any related Sub-Servicers, the Trustee and, if a Non-Trust Mortgage Loan
is affected, the related Non-Trust Mortgage Loan Noteholder, in writing, of any
modification, extension, waiver or amendment of any term of any Mortgage Loan
(including fees charged the Mortgagor) agreed to by it and the date thereof, and
shall deliver to the Trustee or any related Custodian for deposit in the related
Mortgage File (with a copy to be delivered to or retained by, as applicable, the
Master Servicer) and, if a Non-Trust Mortgage Loan is affected, the related
Non-Trust Mortgage Loan Noteholder)), an executed counterpart of the agreement
relating to such modification, extension, waiver or amendment promptly following
execution and delivery thereof, to be followed by an original recorded
counterpart promptly following the recordation (and receipt) thereof.

         (j) To the extent that either the Master Servicer or Special Servicer
waives any Default Charge in respect of any Mortgage Loan, whether pursuant to
Section 3.02(a) or this Section 3.20, the respective amounts of additional
servicing compensation payable to the Master Servicer and the Special Servicer
as Net Default Charges out of such Default Charges shall be reduced
proportionately based upon the respective amounts that would have been payable
thereto as Net Default Charges out of such Default Charges if such waiver had
not been granted.

         (k) If, with respect to any Mortgage Loan (1) under which the lender
can require defeasance in lieu of prepayment, or (2) that permits defeasance,
the Master Servicer shall receive a notice from the related Mortgagor that it
intends to prepay or defease, as applicable, such Mortgage Loan in accordance
with the terms thereof, then the Master Servicer shall, subject to the next
paragraph and the related loan documents, (i) only in the case of a Mortgage
Loan under clause (1) above, promptly respond to such notice in a manner which
would require that the Mortgagor pledge Defeasance Collateral in lieu of such
prepayment pursuant to the terms of the related Mortgage Note, and (ii) notify
each Rating Agency, the Trustee, the Underwriters and the Special Servicer of
the intent to defease such Mortgage Loan, and (iii) upon the written
confirmation from each Rating Agency that the acceptance of a pledge of the
Defeasance Collateral (or, in the case of a Mortgage Loan under clause (1)
above, that the acceptance of a pledge of the Defeasance Collateral in lieu of a
full prepayment) will not result in an

                                     -205-
<PAGE>

Adverse Rating Event with respect to any Class of Certificates or, if the GIC
Office Loan Group is involved, any class of GIC Office Pari Passu Non-Trust
Mortgage Loan Securities rated by such Rating Agency, take such further action
as provided in such Mortgage Note to effectuate such defeasance, including the
purchase and perfection of the Defeasance Collateral on behalf of the Trustee
(as mortgagee of record on behalf of the Certificateholders and, in the case of
a Loan Combination, the affected Non-Trust Mortgage Loan Noteholder(s));
provided that the written confirmation contemplated by clause (iii) above shall
not be required (A) from S&P in the case of a Trust Mortgage Loan (1) with an
unpaid principal balance less than or equal to $20,000,000, (2) that constitutes
less than 5% of the aggregate unpaid principal balance of the Mortgage Pool and
(3) that does not then constitute one of the ten largest (measured by unpaid
principal balance) Trust Mortgage Loans in the Mortgage Pool, provided that, in
lieu of obtaining such written confirmation from S&P, the Master Servicer
delivers to S&P a certification in the form attached hereto as Exhibit M (a
"Defeasance Certificate"), or (B) from Moody's in the case of any Trust Mortgage
Loan that does not then constitute one of the ten largest (measured by unpaid
principal balance) Trust Mortgage Loans in the Mortgage Pool or that does not
then constitute one of the ten largest groups (measured by aggregate unpaid
principal balance) of Trust Mortgage Loans with related Mortgagors, provided
that, in lieu of obtaining such written confirmation from Moody's, the Master
Servicer delivers to Moody's a Defeasance Certificate; and provided, further,
that, the written confirmation contemplated by clause (iii) above shall not be
required from S&P and/or Moody's (provided the Master Servicer delivers a
Defeasance Certificate to the applicable Rating Agency), as applicable, in the
event the subject Trust Mortgage Loan complies with the then current applicable
guidelines set forth by such Rating Agency, or the unpaid principal balance of
the subject Trust Mortgage Loan, the percentage the subject Trust Mortgage Loan
constitutes of the Mortgage Pool or the relative size of the subject Trust
Mortgage Loan with respect to the Mortgage Pool, as applicable, does not exceed
the then current applicable threshold for review as set forth by such Rating
Agency.

         Notwithstanding the foregoing, but subject to the related loan
documents, the Master Servicer shall not permit a pledge of Defeasance
Collateral under a Defeasance Mortgage Loan if (i) such defeasance would occur
within two years of the Startup Day, (ii) the defeasance collateral shall not be
Government Securities; (iii) all costs to be incurred in connection with such
defeasance (including Rating Agency fees, accountants' fees and costs incurred
in connection with any required opinions of counsel) would not be paid by the
related Mortgagor, or (iv) unless such confirmation is not required pursuant to
the first paragraph of this Section 3.20(k), either Rating Agency does not
confirm in writing to the Master Servicer that the acceptance of a pledge of the
Defeasance Collateral (in lieu of a full prepayment, if applicable) will not
result in an Adverse Rating Event with respect to any Class of Certificates or,
if the GIC Office Loan Group is involved, any class of GIC Office Pari Passu
Non-Trust Mortgage Loan Securities rated by such Rating Agency.

         All expenses related to the defeasance of a Defeasance Mortgage Loan
shall be charged to the related Mortgagor or other responsible party.

         (l) With respect to any ARD Mortgage Loan after its Anticipated
Repayment Date, the Master Servicer shall be permitted, subject to obtaining the
Special Servicer's consent, to waive (such waiver to be in writing addressed to
the related Mortgagor, with a copy to the Trustee) all or any portion of the
accrued Additional Interest on such ARD Mortgage Loan if (i) such ARD Mortgage
Loan is a Performing Mortgage Loan, (ii) prior to the related maturity date, the
related Mortgagor has requested the right to prepay such ARD Mortgage Loan in
full together with all payments required under such ARD Mortgage Loan in
connection with such prepayment (except for all or a portion of such

                                     -206-
<PAGE>

accrued Additional Interest), and (iii) the Master Servicer reasonably believes
that it is waiving an amount of Additional Interest in excess of the amount of
such interest that the related Mortgagor is likely to pay and has determined, in
its reasonable, good faith judgment, that the waiver of the Trust's right to
receive such accrued Additional Interest is reasonably likely to produce a
greater payment to Certificateholders (as a collective whole) on a present value
basis (the relevant discounting of anticipated collections that will be
distributable to Certificateholders to be performed at the related Mortgage
Rate) than a refusal to waive the right to such Additional Interest. Neither the
Master Servicer nor the Special Servicer shall have any liability to the Trust,
the Certificateholders or any other Person so long as such determination is
exercised in accordance with the Servicing Standard.

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

         (a) Upon determining that a Servicing Transfer Event has occurred with
respect to any Mortgage Loan that had otherwise been a Performing Mortgage Loan,
and if the Master Servicer is not also the Special Servicer, the Master Servicer
shall immediately give notice thereof (or, if applicable, the Special Servicer
shall immediately give notice thereof to the Master Servicer), and the Master
Servicer shall deliver a copy of the related Servicing File, to the Special
Servicer and shall use reasonable efforts to provide the Special Servicer with
all information, documents (or copies thereof) and records (including records
stored electronically on computer tapes, magnetic discs and the like) relating
to such Mortgage Loan, either in the Master Servicer's or any of its directors',
officers', employees', affiliates' or agents' possession or control or otherwise
available to the Master Servicer without undue burden or expense, and reasonably
requested by the Special Servicer to enable it to assume its functions hereunder
with respect thereto without acting through a Sub-Servicer. The Master Servicer
shall use reasonable efforts to comply with the preceding sentence within five
(5) Business Days of the occurrence of each related Servicing Transfer Event (or
of notice of the occurrence of such Servicing Transfer Event, if applicable);
provided, however, that if the information, documents and records requested by
the Special Servicer are not contained in the Servicing File, the Master
Servicer shall have such period of time as reasonably necessary to make such
delivery. The Special Servicer may conclusively rely on the Master Servicer's
determination (and the Master Servicer may conclusively rely on the Special
Servicer's determination, as applicable) that a Servicing Transfer Event has
occurred giving rise to a Mortgage Loan's becoming a Specially Serviced Mortgage
Loan. The Special Servicer shall not be liable or in default hereunder for any
reasonable act or failure to act because of or arising out of the Master
Servicer's failure to deliver information, documents or records with respect to
any Specially Serviced Mortgage Loan in accordance with the requirements hereof.

         Upon determining that a Specially Serviced Mortgage Loan has become a
Corrected Mortgage Loan, and if the Master Servicer is not also the Special
Servicer, the Special Servicer shall immediately give notice thereof, and shall
within five (5) Business Days of such occurrence return the related Servicing
File, together with any and all new information, documents and records relating
to the subject Mortgage Loan that were not part of the Servicing File when it
was delivered to the Special Servicer, to the Master Servicer (or such other
Person as may be directed by the Master Servicer) and upon giving such notice,
and returning such Servicing File, to the Master Servicer (or such other Person
as may be directed by the Master Servicer), the Special Servicer's obligation to
service such Mortgage Loan, and the Special Servicer's right to receive the
Special Servicing Fee with respect to such Mortgage Loan shall terminate, and
the obligations of the Master Servicer to service and administer such Mortgage
Loan shall resume.

                                     -207-
<PAGE>

         Notwithstanding anything herein to the contrary, in connection with the
transfer to the Special Servicer of the servicing of a Cross-Collateralized
Mortgage Loan as a result of a Servicing Transfer Event or the re-assumption of
servicing responsibilities by the Master Servicer with respect to any such
Mortgage Loan upon its becoming a Corrected Mortgage Loan, the Master Servicer
and the Special Servicer shall each transfer to the other, as and when
applicable, the servicing of all other Cross-Collateralized Mortgage Loans
constituting part of the same Cross-Collateralized Group; provided that no
Cross-Collateralized Mortgage Loan may become a Corrected Mortgage Loan at
anytime that a continuing Servicing Transfer Event exists with respect to
another Cross-Collateralized Mortgage Loan in the same Cross-Collateralized
Group.

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

         (c) Upon request (and to the extent not otherwise already provided by
the Special Servicer pursuant to its reporting obligations hereunder), the
Special Servicer shall deliver to the Master Servicer, the Trustee and each
Rating Agency (or such other Person as may be directed by the Master Servicer) a
statement in writing and in computer readable format (the form of such statement
to be agreed upon by the Master Servicer and the Special Servicer) describing,
on a loan-by-loan and property-by-property basis, (1) insofar as it relates to
Specially Serviced Mortgage Loans and REO Properties, the information described
in clauses (viii) through (xv) of Section 4.02(a) (with respect to information
set forth in such clauses related to prior Distribution Dates and/or periods,
the Special Servicer may conclusively rely on information furnished to it by the
Master Servicer or the Trustee) and, insofar as it relates to the Special
Servicer, the information described in clauses (xxiv) and (xxx) of Section
4.02(a), (2) the amount of all payments, Insurance Proceeds, Condemnation
Proceeds and Liquidation Proceeds received, and the amount of any Realized Loss
incurred, with respect to each Specially Serviced Mortgage Loan during the
related Collection Period, and the amount of Insurance Proceeds, Condemnation
Proceeds and Liquidation Proceeds received, and the amount of any Realized Loss
incurred, with respect to each REO Property during the related Collection
Period, (3) the amount, purpose and date of all Servicing Advances made by the
Special Servicer with respect to each Specially Serviced Mortgage Loan and REO
Property during the related Collection Period, (4) in writing, a brief narrative
summary of the status of each Specially Serviced Mortgage Loan and (5) such
additional information relating to the Specially Serviced Mortgage Loans and REO
Properties as the Master Servicer reasonably requests to enable it to perform
its responsibilities under this Agreement. Notwithstanding the foregoing
provisions of this subsection (c), the Master Servicer shall maintain ongoing
payment records with respect to each of the Specially Serviced Mortgage Loans
and REO Properties and shall provide the Special Servicer with any information
reasonably available to the Master Servicer required by the Special Servicer to
perform its duties under this Agreement.

         SECTION 3.22. Sub-Servicing Agreements.

         (a) Subject to Section 3.22(b) and Section 3.22(f), the Master Servicer
and, subject to Section 3.22(f), the Special Servicer may enter into
Sub-Servicing Agreements to provide for the performance by third parties of any
or all of their respective obligations hereunder, provided that in each case,
the Sub-Servicing Agreement: (i) is consistent with this Agreement in all
material respects,

                                     -208-
<PAGE>

requires the Sub-Servicer to comply with all of the applicable conditions of
this Agreement and, with the exception of Sections 7.01(a)(x) and (xi), provides
for events of default with respect to the Sub-Servicer substantially the same as
those set forth in Section 7.01 (modified as necessary to apply to the
Sub-Servicer's obligations under the Sub-Servicing Agreement); (ii) provides
that if the Master Servicer or the Special Servicer, as the case may be, shall
for any reason no longer act in such capacity hereunder (including by reason of
an Event of Default), the Trustee or its designee may thereupon assume all of
the rights and, except to the extent they arose prior to the date of assumption,
obligations of the Master Servicer or the Special Servicer, as the case may be,
under such agreement or may terminate such sub-servicing agreement without cause
and without payment of any penalty or termination fee (provided, however, that
those Sub-Servicing Agreements in effect as of the Closing Date (or, if being
negotiated as of the Closing Date, in effect within 90 days thereafter) may only
be terminated by the Trustee or its designee as contemplated by Section 3.22(d)
hereof and in such additional manner as is provided in such Sub-Servicing
Agreement); (iii) provides that the Trustee, for the benefit of the
Certificateholders and, in the case of a Sub-Servicing Agreement relating to a
Loan Combination, the related Non-Trust Mortgage Loan Noteholder(s), shall each
be a third party beneficiary under such agreement, but that (except to the
extent the Trustee or its designee assumes the obligations of the Master
Servicer or the Special Servicer, as the case may be, thereunder as contemplated
by the immediately preceding clause (ii)) none of the Trustee, the Trust, any
successor Master Servicer or the Special Servicer, as the case may be, any
Non-Trust Mortgage Loan Noteholder or any Certificateholder shall have any
duties under such agreement or any liabilities arising therefrom; (iv) permits
any purchaser of a Trust Mortgage Loan pursuant to this Agreement to terminate
such agreement with respect to such purchased Trust Mortgage Loan at its option
and without penalty; (v) does not permit the Sub-Servicer to enter into or
consent to any modification, extension, waiver or amendment or otherwise take
any action on behalf of the Master Servicer or the Special Servicer contemplated
by Section 3.08, Section 3.09 and Section 3.20 hereof without the consent of the
Master Servicer or Special Servicer, as the case may be; and (vi) does not
permit the Sub-Servicer any direct rights of indemnification that may be
satisfied out of assets of the Trust Fund. In addition, each Sub-Servicing
Agreement entered into by the Master Servicer (including any with an effective
date on or before the Closing Date) shall provide that such agreement shall,
with respect to any Mortgage Loan serviced thereunder, terminate at the time
such Mortgage Loan becomes a Specially Serviced Mortgage Loan (or,
alternatively, be subject to the Special Servicer's rights to service such
Mortgage Loan for so long as such Mortgage Loan continues to be a Specially
Serviced Mortgage Loan), and each Sub-Servicing Agreement entered into by the
Special Servicer shall relate only to Specially Serviced Mortgage Loans and
shall terminate with respect to any such Mortgage Loan which ceases to be a
Specially Serviced Mortgage Loan. The Master Servicer and the Special Servicer
each shall deliver to the Trustee and each other copies of all Sub-Servicing
Agreements (and, to the related Non-Trust Mortgage Loan Noteholder, a copy of
any Sub-Servicing Agreement in respect of a Non-Trust Mortgage Loan), as well as
any amendments thereto and modifications thereof, entered into by it promptly
upon its execution and delivery of such documents. References in this Agreement
to actions taken or to be taken by the Master Servicer or the Special Servicer
include actions taken or to be taken by a Sub-Servicer on behalf of the Master
Servicer or the Special Servicer, as the case may be; and, in connection
therewith, all amounts advanced by any Sub-Servicer to satisfy the obligations
of the Master Servicer or the Special Servicer hereunder to make P&I Advances or
Servicing Advances shall be deemed to have been advanced by the Master Servicer
or the Special Servicer, as the case may be, out of its own funds and,
accordingly, such P&I Advances or Servicing Advances shall be recoverable by
such Sub-Servicer in the same manner and out of the same funds as if such
Sub-Servicer were the Master Servicer or the Special Servicer, as the case may
be. For so long as they are outstanding, Advances shall accrue interest in
accordance with Sections 3.11(g) or 4.03(d), as applicable, such interest to be
allocable

between the Master Servicer or the Special Servicer, as the case may be, and
such Sub-Servicer as they may agree. For purposes of this Agreement, the Master
Servicer and the Special Servicer each shall be deemed to have received any
payment when a Sub-Servicer retained by it receives such payment. The Master
Servicer and the Special Servicer each shall notify the other, the Trustee, the
Depositor, the Controlling Class Certificateholders and, if a Loan Combination
is involved, the related Non-Trust Mortgage Loan Noteholder(s) in writing
promptly of the appointment by it of any Sub-Servicer.

         (b) Each Sub-Servicer (i) shall be authorized to transact business in
the state or states in which the related Mortgaged Properties it is to service
are situated, if and to the extent required by applicable law, and (ii) except
for any Sub-Servicer that is servicing any of the Mortgage Loans on the Closing
Date, shall be an approved conventional seller/servicer of mortgage loans for
FHLMC or Fannie Mae or a HUD-Approved Servicer.

         (c) The Master Servicer and the Special Servicer, for the benefit of
the Trustee, the Certificateholders and, in the case of a Loan Combination, also
for the benefit of the related Non-Trust Mortgage Loan Noteholder(s), shall (at
no expense to the Trustee, any Certificateholder, any Non-Trust Mortgage Loan
Noteholder or the Trust Fund) monitor the performance and enforce the
obligations of their respective Sub-Servicers under the related Sub-Servicing
Agreements. Such enforcement, including the legal prosecution of claims,
termination of Sub-Servicing Agreements in accordance with their respective
terms and the pursuit of other appropriate remedies, shall be in such form and
carried out to such an extent and at such time as the Master Servicer or the
Special Servicer, as applicable, in its good faith business judgment, would
require were it the owner of the subject Mortgage Loans.

         (d) In the event of the resignation, removal or other termination of
the Master Servicer or any successor Master Servicer hereunder for any reason,
the Trustee or other Person succeeding such resigning, removed or terminated
party as Master Servicer, shall elect, with respect to any Sub-Servicing
Agreement in effect as of the Closing Date (or, if being negotiated as of the
Closing Date, in effect within 90 days thereafter) that still exists at the time
of such termination: (i) to assume the rights and obligations of the Master
Servicer under such Sub-Servicing Agreement and continue the sub-servicing
arrangements thereunder on the same terms (including the obligation to pay the
same sub-servicing fee); (ii) to enter into a new Sub-Servicing Agreement with
such Sub-Servicer on such terms as the Trustee or other successor Master
Servicer and such Sub-Servicer shall mutually agree (it being understood that
such Sub-Servicer is under no obligation to accept any such new Sub-Servicing
Agreement or to enter into or continue negotiations with the Trustee or other
successor Master Servicer), provided that neither the Trustee nor any successor
Master Servicer shall enter into a new Sub-Servicing Agreement with a
Sub-Servicer that was a party to a Sub-Servicing Agreement as of the Closing
Date, if such new Sub-Servicing Agreement amends, alters or fails to restate any
rights of any Underwriter or Mortgage Loan Seller under the existing
Sub-Servicing Agreement with respect to the termination of the Sub-Servicer and
the appointment of a successor thereto or any rights of any Underwriter or
Mortgage Loan Seller as a third party beneficiary under such Sub-Servicing
Agreement, unless the successor Master Servicer has obtained the prior written
consent to the terms of such new Sub-Servicing Agreement from such Underwriter
or Mortgage Loan Seller, as the case may be; or (iii) to terminate the
Sub-Servicing Agreement if (but only if) an Event of Default (as defined in such
Sub-Servicing Agreement) has occurred and is continuing, without paying any
sub-servicer termination fee, and in any additional manner provided for in such
Sub-Servicing Agreement.

and the Special Servicer shall remain obligated and liable to the Trustee, the
Certificateholders and the Non-Trust Mortgage Loan Noteholder(s) for the
performance of their respective obligations and duties under this Agreement in
accordance with the provisions hereof to the same extent and under the same
terms and conditions as if each alone were servicing and administering the

any Sub-Servicing Agreement without the approval of the Controlling Class

and the Special Servicer to appoint a Sub-Servicer with respect to the MGM Tower
Loan Pair will be subject to Section 3.02(d) of the MGM Tower Co-Lender
Agreement.

         Master Servicer, and the performance and compliance with the terms of

         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 material instrument to which it is a party or which is applicable
         to it or any of its assets.

                  (iii) The Master Servicer has the full power and authority to

         any order, regulation or demand of any federal, state or local

         perform its obligations under this Agreement or the financial condition
         of the Master Servicer.

                  (vi) No litigation is pending or, to the best of the Master
         Servicer's knowledge, threatened, against the Master Servicer, the
         outcome of which, in the Master Servicer's good faith and reasonable
         judgment, could reasonably be expected to prohibit the Master Servicer
         from entering into this Agreement or materially and adversely affect
         the ability of the Master Servicer to perform its obligations under
         this Agreement.

                  (vii) Any consent, approval, authorization or order of any
         court or governmental agency or body required under federal or state
         law for the execution, delivery and performance by the Master Servicer
         of or compliance by the Master Servicer with this Agreement or the
         consummation of the transactions contemplated by this Agreement has
         been obtained and is effective except where the lack of consent,
         approval, authorization or order would not have a material adverse
         effect on the performance by the Master Servicer under this Agreement.

in Section 3.23(a) shall survive the execution and delivery of this Agreement
and shall inure to the benefit of the Persons for whose benefit they were made

         execution and delivery of this Agreement and its performance and
         compliance with the terms of this Agreement will not constitute a

         any order, regulation or demand of any federal, state or local
         governmental or regulatory authority, which violation, in the Special
         Servicer's good faith and reasonable judgment, is likely to affect

         SECTION 3.25. Certain Matters Regarding the Purchase of the MGM Tower
                       Trust Mortgage Loan and the GIC Office Trust Mortgage
                       Loan.

         (a) If, pursuant to or as contemplated by Section 2.03, Section 3.18 or
Section 9.01, the MGM Tower Trust Mortgage Loan is purchased or repurchased from
the Trust Fund, the purchaser thereof shall be bound by the terms of the MGM
Tower Co-Lender Agreement and shall assume the rights and obligations of the
"Note A Lender" under the MGM Tower Co-Lender Agreement. All portions of the
related Mortgage File and other documents pertaining to such Trust Mortgage Loan
shall be endorsed or assigned, to the extent necessary or appropriate, to the
purchaser of such Trust Mortgage Loan in its capacity as "Note A Lender" (as a
result of such purchase or repurchase) under the MGM Tower Co-Lender Agreement
in the manner contemplated under such agreement, which such purchaser shall be
deemed to acknowledge. Thereafter such Mortgage File shall be held by the Note A
Lender or a custodian appointed thereby for the benefit of the "Note A Lender"
and the "Note B Lender" as their interests appear under such Co-Lender
Agreement. If the related Servicing File is not already in the possession of
such party, it shall be delivered to the successor master servicer or special
servicer, as the case may be, with respect to the MGM Tower Loan Pair, under, or
otherwise in accordance with, any applicable separate servicing agreement for

from the Trust Fund, the purchaser thereof shall be bound by the terms of the
GIC Office Co-Lender Agreement and shall assume the rights and obligations of
the "Controlling Note A-1 Lender" under the GIC Office Co-Lender Agreement. All

capacity as "Controlling Note A-1 Lender" (as a result of such purchase or
repurchase) under the GIC Office Co-Lender Agreement in the manner contemplated

or a custodian appointed thereby for the benefit of each of the "Note A Lenders"
and the "Note B Lender" each as defined under, and as their interests appear
under, the GIC Office Co-Lender Agreement. If the related Servicing File is not
already in the possession of such party, it shall be delivered to the successor
master servicer or special servicer, as the case may be, with respect to the GIC
Office Loan Group under, or otherwise in accordance with, any applicable
separate servicing agreement for the GIC Office Loan Group or as otherwise
contemplated by the GIC Office Co-Lender Agreement.

         owing to such party on any outstanding Advances made thereby with
         respect to such Trust Mortgage Loan or REO Trust Mortgage Loan, as the
         case may be, which interest on such outstanding Advance accrued on or
         prior to the date on which the subject Default Charges were received;

                  second, to pay any other outstanding expenses (exclusive of
         Special Servicing Fees, Liquidation Fees and Workout Fees) incurred
         with respect to such Trust Mortgage Loan or REO Trust Mortgage Loan, as
         the case may be, that, if paid from collections on the Mortgage Pool
         other than such Default Charges, would constitute an Additional Trust
         Fund Expense;

                  third, to reimburse the Trust for any interest on Advances
         paid to the Fiscal Agent, the Trustee, the Master Servicer or the
         Special Servicer since the Closing Date with respect to such Trust

         interest payment was made from collections on the Mortgage Pool other
         than Default Charges on such Trust Mortgage Loan or REO Trust Mortgage
         Loan and was not previously reimbursed under this clause third;

                  fourth, to reimburse the Trust for any other Additional Trust

         and Workout Fees) paid since the Closing Date with respect to such
         Trust Mortgage Loan or REO Trust Mortgage Loan, as the case may be,
         which payment was made from collections on the Mortgage Pool other than
         Default Charges on such Trust Mortgage Loan or REO Trust Mortgage Loan
         and was not previously reimbursed under this clause fourth; and

                  fifth, to pay any remaining portion of such Default Charges
         (such remaining portion, "Net Default Charges") as additional master
         servicing compensation to the Master Servicer, to the extent received,
         if they were accrued in respect of a Performing Trust Mortgage Loan, or
         as additional special servicing compensation to the Special Servicer,
         to the extent received, if they were accrued in respect of a Specially
         Serviced Trust Mortgage Loan or an REO Trust Mortgage Loan, in each
         case pursuant to Section 3.11;

provided that any and all Default Charges that are actually collected with
respect to the GIC Office Trust Mortgage Loan or any successor REO Trust
Mortgage Loan with respect thereto shall first be applied pursuant to Section
3.05A, Section 3.26(d) and the GIC Office Co-Lender Agreement; and provided,
further, that any and all Default Charges that are actually collected with
respect to the MGM Tower Trust Mortgage Loan or any successor REO Trust Mortgage
Loan with respect thereto shall first be applied pursuant to Section 3.05B and
the MGM Tower Co-Lender Agreement; and provided, further, that the total
interest on Advances payable pursuant to clause first above shall take into
account the application of funds on deposit in the respective Loan Combination
Custodial Accounts to pay interest on Advances.

         (b) Default Charges applied to reimburse the Trust pursuant to clauses
third and fourth of subsection (a), are intended to be part of the amounts to be
delivered by the Master Servicer to the Trustee pursuant to the first paragraph
of Section 3.04(b) on or before the Trust Master Servicer Remittance Date next
following the applicable Collection Period during which they were received, for
deposit in the Collection Account, subject to application pursuant to Section
3.05(a) for any items payable out of general collections on the Mortgage Pool.
Default Charges applied to pay outstanding interest on Advances in respect of
the related Trust Mortgage Loan or REO Trust Mortgage Loan, as applicable, to
any particular party, pursuant to clause first of subsection (a), shall be
applied to pay such party such interest on Advances in such manner that the
interest that accrued first and has been outstanding the longest shall be paid
first. Default Charges applied to pay outstanding expenses in respect of the
related Trust Mortgage Loan or REO Trust Mortgage Loan, as applicable, pursuant
to clause second of subsection (a), shall be applied to pay such expenses in the
chronological order in which they were incurred. Default Charges applied to
reimburse the Trust pursuant to clauses third and fourth of subsection (a) shall
be deemed to offset either interest paid on Advances or other Additional Trust
Fund Expenses, depending on which clause is applicable, in respect of the
related Trust Mortgage Loan or REO Trust Mortgage Loan, as applicable, in the
chronological order in which such interest accrued or such expenses were
incurred, as applicable (whereupon such interest paid on Advances or such other

Mortgage Loan with respect thereto on any GIC Office Master Servicer Remittance
Date, in accordance with the GIC Office Co-Lender Agreement, shall be applied
for the following purposes and in the following order, in each case to the
extent of the remaining portion of such amounts, prior to being so distributed
to the GIC Office Subordinate Non-Trust Mortgage Loan Noteholder:

                  first, to pay to the Fiscal Agent, the Trustee, the Master
         Servicer and the Special Servicer any and all interest on any Servicing
         Advances made thereby with respect to the GIC Office Loan Group or any
         related REO Property, which interest accrued on or prior to the date on
         which such amounts otherwise so distributable as Default Charges were
         received (such amounts to be applied in accordance with this clause
         first with respect to any such particular party in such manner that the
         earliest accrued interest shall be paid first); and

                  second, to pay the Fiscal Agent, the Trustee, any fiscal agent
         and/or trustee for a GIC Office Pari Passu Securitization Trust, the

         Non-Trust Mortgage Loan Securitization Agreement made by such party
         with respect to the GIC Office Trust Mortgage Loan, a GIC Office Pari
         Passu Non-Trust Mortgage Loan or any successor REO Mortgage Loan with
         respect to the foregoing, which interest accrued on or prior to the
         date on which such amounts otherwise so distributable as Default
         Charges were received (such amounts to be applied in accordance with
         this clause second with respect to any such particular party in such
         manner that the earliest accrued interest shall be paid first).

         Any amounts otherwise distributable to the GIC Office Subordinate
Non-Trust Mortgage Loan Noteholder as Default Charges with respect to the GIC
Office Subordinate Non-Trust Mortgage Loan or any successor REO Mortgage Loan
with respect thereto that are applied pursuant to clause first of the preceding
paragraph shall be paid to the Fiscal Agent, the Trustee, the Master Servicer
and the Special Servicer, in that order, in each case up to the total amount of
interest on any Servicing Advances payable to such party in accordance with such
clause first. Any amounts otherwise distributable to the GIC Office Subordinate
Non-Trust Mortgage Loan Noteholder as Default Charges with respect to the GIC
Office Subordinate Non-Trust Mortgage Loan or any successor REO Mortgage Loan
with respect thereto that are applied pursuant to clause second of the preceding
paragraph shall be allocated among the GIC Office Trust Mortgage Loan and the
GIC Office Pari Passu Non-Trust Mortgage Loans (or, if applicable, among any

         R-III and Class R-II Certificates on such Distribution Date pursuant to
         clauses (i) through (l) of this Section 4.01(b).

         (c) On each Distribution Date, the Trustee shall withdraw from the
Collection Account any amount received with respect to any Trust Mortgage Loan
or REO Trust Mortgage Loan during the related Collection Period that represents
Net Prepayment Consideration and shall distribute such Net Prepayment
Consideration: first, to the Holders of the respective Classes of YM Principal
Balance Certificates that are entitled to distributions of principal on such
Distribution Date, pursuant to Section 4.01(a) or Section 4.01(b), up to an
amount equal to, and pro rata based on, the respective Prepayment Consideration
Entitlements for such Classes of Certificates for such Distribution Date in
connection with such Net Prepayment Consideration; and second, to either (i) the
Holders of the Class X-ST Certificates, if such Net Prepayment Consideration
relates to the UBS Center Trust Mortgage Loan or any successor REO Trust
Mortgage Loan with respect thereto, or (ii) to the Holders of the Class X-CL
Certificates, in all other cases, up to any remaining amount of such Net
Prepayment Consideration.

         Any Net Prepayment Consideration or portion thereof distributed in
respect of the Class X-CL Certificates on any Distribution Date shall be deemed
to have been distributed in respect of the

                                     -227-
<PAGE>

respective REMIC III Components of the Class X-CL Certificates, on a pro rata
basis in accordance with the respective amounts by which the Component Notional
Amounts of such REMIC III Components were reduced on such Distribution Date by
deemed distributions of principal pursuant to Section 4.01(j).

         (d) On each Distribution Date, the Trustee shall withdraw from the
Collection Account any amounts that represent Additional Interest received
during the related Collection Period with respect to the ARD Trust Mortgage
Loans (and any successor REO Trust Mortgage Loans with respect thereto) and
shall distribute such amounts to the Holders of the Class V Certificates.

         (e) 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.
Except as otherwise provided below, all such distributions with respect to each
Class on each Distribution Date shall be made to the Certificateholders of the
respective Class of record at the close of business on the related Record Date
and shall be made by wire transfer of immediately available funds to the account
of any such Certificateholder at a bank or other entity having appropriate
facilities therefor, if such Certificateholder shall have provided the Trustee
with wiring instructions no less than five (5) Business Days prior to (or, in
the case of the initial Distribution Date, no later than) the related Record
Date (which wiring instructions may be in the form of a standing order
applicable to all subsequent Distribution Dates), or otherwise by check mailed
to the address of such Certificateholder as it appears in the Certificate
Register. The final distribution on each Certificate (determined, in the case of
a Principal Balance Certificate, without regard to any possible future
reimbursement of any related Loss Reimbursement Amount) will be made in a like
manner, but only upon presentation and surrender of such Certificate at the
offices of the Certificate Registrar or such other location specified in the
notice to Certificateholders of such final distribution. Prior to any
termination of the Trust Fund pursuant to Section 9.01, any distribution that is
to be made with respect to a Certificate in reimbursement of a Realized Loss or
Additional Trust Fund Expense previously allocated thereto, which reimbursement
is to occur after the date on which such Certificate is surrendered as
contemplated by the preceding sentence, will be made by check mailed to the
address of the Certificateholder that surrendered such Certificate as such
address last appeared in the Certificate Register or to any other address of
which the Trustee was subsequently notified in writing. If such check is
returned to the Trustee, then the Trustee, directly or through an agent, shall
take such reasonable steps to contact the related Holder and deliver such check
as it shall deem appropriate. Any funds in respect of a check returned to the
Trustee shall be set aside by the Trustee and held uninvested in trust and
credited to the account of the appropriate Holder. The costs and expenses of
locating the appropriate Holder and holding such funds shall be paid out of such
funds. No interest shall accrue or be payable to any former Holder on any amount
held in trust hereunder. If the Trustee has not, after having taken such
reasonable steps, located the related Holder by the second anniversary of the
initial sending of a check, the Trustee shall, subject to applicable law,
distribute the unclaimed funds to the Class R-III Certificateholders.

         (f) Each distribution with respect to a Book-Entry Certificate shall be
paid to the Depository, as Holder thereof, and the Depository shall be
responsible for crediting the amount of such distribution to the accounts of its
Depository Participants in accordance with its normal procedures. Each
Depository Participant shall be responsible for disbursing such distribution to
the related Certificate Owners that it represents and to each indirect
participating brokerage firm for which it acts as agent. Each indirect
participating brokerage firm shall be responsible for disbursing funds to the
related

                                     -228-
<PAGE>

Certificate Owners that it represents. None of the Trustee, the Certificate
Registrar, the Depositor or the Master Servicer shall have any responsibility
therefor except as otherwise provided by this Agreement or applicable law. The
Trustee and the Depositor shall perform their respective obligations under each
Letter of Representations among the Depositor, the Trustee and the initial
Depository dated as of the Closing Date and pertaining to the Book-Entry
Certificates.

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

         (h) Except as otherwise provided in Section 9.01, whenever the Trustee
receives written notification of or expects that the final distribution with
respect to any Class of Certificates (determined, in the case of a Class of
Principal Balance Certificates, without regard to any possible future
reimbursement of any Realized Loss or Additional Trust Fund Expense previously
allocated to such Class of Certificates pursuant to Section 4.04(a)) will be
made on the next Distribution Date, the Trustee shall, no later than the second
Business Day prior to such Distribution Date, mail to each Holder of record of
such Class of Certificates on such date a notice to the effect that:

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

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

Any funds not distributed to any Holder or Holders of Certificates of such Class
on such Distribution Date because of the failure of such Holder or Holders to
tender their Certificates shall, on such date, be set aside and held uninvested
in trust and credited to the account or accounts of the appropriate
non-tendering Holder or Holders. If any Certificates as to which notice has been
given pursuant to this Section 4.01(h) 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, then the Trustee, directly or through an agent, shall take such
steps to contact the remaining non-tendering Certificateholders concerning the
surrender of their Certificates as it shall deem appropriate. The costs and
expenses of holding such funds in trust and of contacting such non-tendering
Certificateholders following the first anniversary of the delivery of such
second notice thereto shall be paid out of such funds. No interest shall accrue
or be payable to any former Holder on any amount held in trust pursuant to this
paragraph. If all of the Certificates as to which notice has been given pursuant
to this Section 4.01(h) shall not have been surrendered for cancellation by the
second anniversary of the delivery of the second notice, the Trustee shall,
subject to applicable law, distribute to the Class R-III Certificateholders all
unclaimed funds and other assets which remain subject thereto.

         (i) Notwithstanding any other provision of this Agreement, the Trustee
shall comply with all federal withholding requirements respecting payments to
Certificateholders of interest or

                                     -229-
<PAGE>

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

         (j) All distributions made in respect of each Class of Principal
Balance Certificates on each Distribution Date (including the Final Distribution
Date) pursuant to Section 4.01(a), Section 4.01(b), Section 4.01(c) or Section
9.01 shall be deemed to have first been distributed from REMIC II to REMIC III
with respect to the Corresponding REMIC II Regular Interest(s) for such Class of
Certificates; all distributions made with respect to the Class X-ST Certificates
on each Distribution Date pursuant to Section 4.01(a), Section 4.01(c) or
Section 9.01 shall be deemed to have been first distributed from REMIC II to
REMIC III in respect of REMIC II Regular Interest X-ST; and all distributions
made with respect to each Class of Interest-Only Certificates (other than the
Class X-ST Certificates) on each Distribution Date pursuant to Section 4.01(a),
Section 4.01(c) or Section 9.01 and allocable to any particular REMIC III
Component of such Class of Certificates, shall be deemed to have first been
distributed from REMIC II to REMIC III in respect of the Corresponding REMIC II
Regular Interest for such REMIC III Component. In each case, if such
distribution on any such Class of Certificates was a distribution of accrued
interest, of principal, of additional interest (in the form of Net Prepayment
Consideration or any portion thereof) or in reimbursement of any Loss
Reimbursement Amount with respect to such Class of Certificates, then the
corresponding distribution deemed to be made on a REMIC II Regular Interest
pursuant to the preceding sentence (and, if applicable, the second following
paragraph of this Section 4.01(j)) shall be deemed to also be, respectively, a
distribution of accrued interest, of principal, of additional interest (in the
form of Net Prepayment Consideration or any portion thereof) or in reimbursement
of any Loss Reimbursement Amount with respect to such REMIC II Regular Interest.

         If a Class of Principal Balance Certificates has two or more
Corresponding REMIC II Regular Interests, then:

                  (i) deemed distributions of accrued interest made on such
         Corresponding REMIC II Regular Interests on any Distribution Date shall
         be allocated between or among them, as applicable, on a pro rata basis
         in accordance with the respective amounts of Uncertificated
         Distributable Interest in respect of such Corresponding REMIC II
         Regular Interests for such Distribution Date and, to the extent not
         previously deemed distributed, for all prior Distribution Dates, if
         any;

                  (ii) deemed distributions of principal made on such
         Corresponding REMIC II Regular Interests on any Distribution Date shall
         be allocated to them in numeric order (i.e., from lowest number to
         highest number) of the respective ending numbers of the respective
         alphanumeric designations for such Corresponding REMIC II Regular
         Interests, in each case up to an amount equal to the Uncertificated
         Principal Balance of the subject Corresponding REMIC II Regular
         Interest outstanding immediately prior to such Distribution Date (such
         that no deemed distributions of principal will be made on any such
         Corresponding REMIC II Regular Interest until the Uncertificated
         Principal Balance of each other such Corresponding REMIC II Regular
         Interest, if any, with an alphanumeric designation that ends in a lower
         number, has been paid in full);

                                     -230-
<PAGE>

                  (iii) deemed distributions of additional interest (in the form
         of Net Prepayment Consideration or any portion thereof) made on such
         Corresponding REMIC II Regular Interests on any Distribution Date shall
         be allocated between or among them, as applicable, on a pro rata basis
         in accordance with the respective amounts of principal deemed
         distributed in respect of such Corresponding REMIC II Regular Interests
         on such Distribution Date; and

                  (iv) deemed distributions made on such Corresponding REMIC II
         Regular Interests on any Distribution Date in reimbursement of the Loss
         Reimbursement Amounts with respect thereto shall be allocated to them
         in reverse order that deemed distributions of principal made on such
         Corresponding REMIC II Regular Interests are allocated to them pursuant
         to subclause (ii) of Section 4.01(j), in each case, up to the amount of
         the Loss Reimbursement Amount with respect to the subject REMIC II
         Regular Interest for such Distribution Date.

         The actual distributions made by the Trustee on each Distribution Date
in respect of the REMIC III Certificates pursuant to Section 4.01(a), Section
4.01(b), Section 4.01(c) or Section 9.01, as applicable, shall be deemed to have
been so made from the amounts deemed distributed with respect to the REMIC II
Regular Interests on such Distribution Date pursuant to this Section 4.01(j).
Notwithstanding the deemed distributions on the REMIC II Regular Interests
described in this Section 4.01(j), actual distributions of funds from the
Collection Account shall be made only in accordance with Section 4.01(a),
Section 4.01(b), Section 4.01(c), Section 4.01(d) or Section 9.01, as
applicable.

         (k) On each Distribution Date, including the Final Distribution Date,
the Available Distribution Amount for such Distribution Date shall be deemed to
have been distributed from REMIC I to REMIC II for the following purposes and in
the following order of priority, in each case to the extent of the remainder of
such funds:

                  (i) as deemed distributions of interest with respect to all
         the REMIC I Regular Interests, up to an amount equal to, and pro rata
         in accordance with, all Uncertificated Distributable Interest with
         respect to each REMIC I Regular Interest for such Distribution Date
         and, to the extent not previously deemed distributed, for all prior
         Distribution Dates, if any;

                  (ii) as deemed distributions of principal with respect to all
         the REMIC I Regular Interests, up to an amount equal to, and pro rata
         in accordance with, as to each REMIC I Regular Interest, the portion of
         the Principal Distribution Amount for such Distribution Date
         attributable to the related Trust Mortgage Loan or any successor REO
         Trust Mortgage Loan with respect thereto; and

                  (iii) as deemed distributions of reimbursement with respect to
         all the REMIC I Regular Interests, up to an amount equal to, and pro
         rata in accordance with, any Loss Reimbursement Amount with respect to
         each REMIC I Regular Interest for such Distribution Date (with
         compounded interest at the related REMIC I Remittance Rate in effect
         from time to time on the aggregate amount of unreimbursed reductions
         made from time to time in the Uncertificated Principal Balance of such
         REMIC I Regular Interest pursuant to Section 4.04(c)).

         Any Net Prepayment Consideration distributed to any Class of Regular
Interest Certificates on any Distribution Date shall, in each case, be deemed to

Notwithstanding the foregoing, upon the Depositor's notifying the Master
Servicer that the Non-Registered Certificates have been sold by the Underwriters
to unaffiliated third parties, the Master Servicer may make the Servicer Reports
available on its internet website without a password, provided that for so long
as reports are required to be filed with the Commission in respect of the Trust
pursuant

                                     -236-

to Section 15(d) of the Exchange Act, the subject reports shall have
been previously filed with the Commission (which shall be confirmed by the
Master Servicer by request made to the Trustee).

         If the Master Servicer determines, in its reasonable judgment, that
information regarding the Trust Mortgage Loans and REO Properties (in addition
to the information otherwise required to be contained in the CMSA Investor
Reporting Package) should be disclosed to Certificateholders and Certificate
Owners, then (A) the Master Servicer shall so notify the Trustee, set forth such
information in an additional report, in a format reasonably acceptable to the
Trustee and the Master Servicer (the "Supplemental Report"), and deliver such
report to the Trustee upon preparation thereof or simultaneously with the
delivery of its reports described in Section 3.12(c); and (B) the Trustee shall

Commission with respect to the Trust pursuant to Section 15(d) of the Exchange
Act, each recipient of a Certificateholder Report, a CMSA NOI Adjustment

agreed to keep confidential the information therein until such statement or
report is filed with the Commission, and each Certificateholder Report, CMSA NOI
Adjustment Worksheet and CMSA Operating Statement Analysis Report shall bear a
legend to the effect that: "Until this statement/report is filed with the
Commission with respect to the Trust pursuant to Section 15(d) of the Securities
Exchange Act of 1934, as amended, the recipient hereof shall be deemed to keep
the information contained herein confidential and such information will not,
without the prior consent of the Master Servicer or the Trustee, be disclosed by
such recipient or by its officers, directors, partners, employees, agents or
representatives in any manner whatsoever, in whole or in part."

         Absent manifest error of which it has actual knowledge, none of the
Master Servicer, the Special Servicer or the Trustee shall be responsible for

materials or information prepared or provided by the Master Servicer, the
Special Servicer or the Trustee, as applicable, pursuant to this Agreement. None
of the Trustee, the Master Servicer or the Special Servicer shall have any
obligation to verify the accuracy or completeness of any information provided by
a Mortgagor, a Mortgage Loan Seller, a third party or each other.

         Within a reasonable period of time after the end of each calendar year,

the applicable portion of such calendar year during which such Person was a
Certificateholder) set forth in the Distribution Date Statements and such other
information as may be required to enable such Certificateholder to prepare its
federal income tax returns. Such information shall include the amount of
original issue discount accrued on each Class of Certificates and information
regarding the expenses of the Trust Fund. Such requirement shall be deemed to be
satisfied to the extent such information is provided pursuant to applicable
requirements of the Code from time to time in force.

         If any Certificate Owner does not receive through the Depository or any

written information described above in this Section 4.02(a) that it would
otherwise be entitled to receive if it were the Holder of a Definitive

request of such Certificate Owner made in writing to the Corporate Trust Office
(accompanied by current verification of such Certificate Owner's ownership
interest). Such portion of such information as may be agreed upon by the
Depositor and the Trustee shall be furnished to any such Person via overnight
courier delivery or telecopy from the Trustee; provided that the cost of such
overnight courier delivery or telecopy shall be an expense of the party
requesting such information.

         The Trustee shall only be obligated to deliver the statements, reports
and information contemplated by this Section 4.02(a) to the extent it receives,
in the format required by this Agreement, the necessary underlying information
from the Master Servicer or the Special Servicer, as applicable, and shall not
be liable for any failure to deliver any thereof on the prescribed due dates, to
the extent caused by failure to receive timely such underlying information.
Nothing herein shall obligate the Trustee, the Master Servicer or the Special
Servicer to violate any applicable law prohibiting disclosure of information
with respect to any Mortgagor and the failure of the Trustee, Master Servicer or
the Special Servicer to disseminate information for such reason shall not be a
breach hereof.

         The information to be furnished by the Trustee to the
Certificateholders pursuant to this Section 4.02 shall not limit the Trustee in
furnishing any such information to other Persons to whom it determines such
disclosure to be appropriate and shall not limit the Trustee in furnishing to
Certificateholders or to any Person any other information with respect to the
Trust Mortgage Loans, the Mortgaged Properties or the Trust Fund as may be
provided to it by the Depositor, the Master Servicer or the Special Servicer or
gathered by it in any investigation or other manner from time to time (such
information, other than as described in this Section 4.02, is referred to herein
as "Additional Information") as it may reasonably deem necessary or appropriate
from time to time, provided that

deems appropriate in its reasonable discretion, (D) the Trustee shall notify
Certificateholders of the availability of any such information in any manner as
it, in its sole discretion, may determine, and (E) this provision shall not
prevent the Trustee, whether with or without the consent of the Depositor, from
furnishing information with respect to the Trust Fund and its administration
thereof to any Person, if it reasonably determines that the furnishing of such
information is required by applicable law. The Trustee shall forward to the
Depositor any requests for Additional Information which, for their fulfillment,
require the consent of the Depositor. Nothing herein shall be construed to
impose upon the Trustee any obligation or duty to furnish or distribute any
Additional Information to any Person in any instance.

Loans as of the related Determination Date.

         In the performance of its obligations set forth in Section 4.06 and its
other duties hereunder, the Trustee may conclusively rely on the CMSA Loan
Periodic Update File provided to it by the Master Servicer, and the Trustee
shall not be responsible to recompute, recalculate or verify the information
provided to it by the Master Servicer. In the case of information to be
furnished by the Master Servicer to the Trustee pursuant to this Section
4.02(b), insofar as such information is solely within the control of the Special
Servicer, the Master Servicer (if other than the Special Servicer or an
Affiliate thereof) shall have no obligation to provide such information until it
has received such information from the Special Servicer, shall not be in default
hereunder due to a delay in providing the CMSA Loan Periodic Update File caused
by the Special Servicer's failure to timely provide any report required under
this Agreement and may, absent actual knowledge of an error therein,
conclusively rely on the reports to be provided by the Special Servicer. The
Master Servicer may conclusively rely on any information provided by the
respective Mortgage Loan Sellers or any Mortgagor with respect to the CMSA Loan
Periodic Update File, CMSA Loan Setup File, CMSA Property File and CMSA
Financial File.

         SECTION 4.03. P&I Advances With Respect to the Mortgage Pool.

         (a) On or before 2:00 p.m., New York City time, on each Trust Master
Servicer Remittance Date, the Master Servicer shall, subject to Section 4.03(c)
below, satisfy its obligations to make any required P&I Advances with respect to
the related Distribution Date in respect of the Mortgage Pool, first, by
transferring to the Trustee for deposit in the Collection Account amounts then
held in the Pool Custodial Account for future distribution to Certificateholders
in subsequent months in discharge of such obligations, and second, by remitting
its own funds to the Trustee for deposit in the Collection Account in an amount
equal to the remaining portion of such required P&I Advances. Any amounts held
in the Pool Custodial Account for future distribution and so used to make P&I
Advances shall be appropriately reflected in the Master Servicer's records and
replaced by the Master Servicer by deposit in the Pool Custodial Account on or
before the next succeeding applicable Determination Date

                                     -239-
<PAGE>

(to the extent not previously replaced through the deposit of Late Collections
of the delinquent principal and interest in respect of which such P&I Advances
were made). If, as of 4:00 p.m., New York City time, on any Trust Master
Servicer Remittance Date, the Master Servicer shall not have made any P&I
Advance required to be made on such date pursuant to this Section 4.03(a) (and
shall not have delivered to the Trustee the requisite Officer's Certificate and
any required supporting documentation related to a determination of
nonrecoverability of a P&I Advance), then the Trustee shall provide notice of
such failure to a Servicing Officer of the Master Servicer by facsimile
transmission sent to telecopy no. (704) 715-0036 (or such alternative number
provided by the Master Servicer to the Trustee in writing) and by telephone at
telephone no. (704) 593-7682 or (704) 593-7867 (or such alternative number
provided by the Master Servicer to the Trustee in writing) as soon as possible,
but in any event before 5:00 p.m., New York City time, on such Trust Master
Servicer Remittance Date. If after such notice by facsimile, the Trustee does
not receive the full amount of such P&I Advances by 10:00 a.m., New York City
time, on the related Distribution Date, then the Trustee (or the Fiscal Agent on
its behalf) shall make the portion of such P&I Advances that was required to be,
but was not, made by the Master Servicer on such Trust Master Servicer
Remittance Date. If the Trustee fails to make any such P&I Advance on the
related Distribution Date, but the Fiscal Agent makes such P&I Advance on such
date, then the Trustee shall be deemed not to be in default hereunder.

         No party hereto shall be required to make a P&I Advance with respect to
any Non-Trust Mortgage Loan or any successor REO Mortgage Loan with respect
thereto.

         (b) The aggregate amount of P&I Advances to be made by the Master
Servicer, the Trustee or the Fiscal Agent, as the case may be, pursuant to this
Section 4.03 in respect of any Distribution Date shall, subject to Section
4.03(c) below, equal the aggregate of all Monthly Payments (other than Balloon
Payments) and any Assumed Monthly Payments, in each case net of related Master
Servicing Fees and any related Workout Fees due or deemed due, as the case may
be, in respect of the Trust Mortgage Loans (including Balloon Trust Mortgage
Loans delinquent as to their respective Balloon Payments) and any REO Trust
Mortgage Loans in the Mortgage Pool on their respective Due Dates during the
related Collection Period, in each case to the extent such amount was not paid
by or on behalf of the related Mortgagor or otherwise collected (including as
net income from any related REO Property) as of the end of the related
Collection Period; provided that if it is determined that an Appraisal Reduction
Amount exists with respect to any Loan Combination and, further, that a portion
of such Appraisal Reduction Amount is allocable to the Trust Mortgage Loan or
REO Trust Mortgage Loan, as applicable, that is part of such Loan Combination,
then the interest portion of each P&I Advance, if any, required to be made
pursuant to this Section 4.03 with respect to such Trust Mortgage Loan or REO
Trust Mortgage Loan, as the case may be, during the period that such Appraisal
Reduction Amount continues to exist, shall be reduced to equal the product of
(i) the amount of the interest portion of the subject P&I Advance that would
otherwise be required to be made under this Section 4.03 in respect of such
Trust Mortgage Loan or REO Trust Mortgage Loan, as the case may be, without
regard to this proviso, multiplied by (ii) a fraction, the numerator of which is
equal to the then Stated Principal Balance of such Trust Mortgage Loan or REO
Trust Mortgage Loan, as the case may be, net of the portion of such Appraisal
Reduction Amount that is allocable to such Trust Mortgage Loan or REO Trust
Mortgage Loan, as the case may be, and the denominator of which is equal to the
then Stated Principal Balance of such Trust Mortgage Loan or REO Trust Mortgage
Loan, as the case may be; and provided, further, that if it is determined that
an Appraisal Reduction Amount exists with respect to any Trust Mortgage Loan or
REO Trust Mortgage Loan that is not part of a Loan Combination, then the
interest portion of each P&I Advance, if any, required to be made pursuant to
this Section 4.03 with

                                     -240-
<PAGE>

respect to such Trust Mortgage Loan or REO Trust Mortgage Loan, as the case may
be, during the period that such Appraisal Reduction Amount continues to exist,
shall be reduced to equal the product of (i) the amount of the interest portion
of the subject P&I Advance that would otherwise be required to be made under
this Section 4.03 in respect of such Trust Mortgage Loan or REO Trust Mortgage
Loan, as the case may be, without regard to this proviso, multiplied by (ii) a
fraction, the numerator of which is equal to the then Stated Principal Balance
of such Trust Mortgage Loan or REO Trust Mortgage Loan, as the case may be, net
of such Appraisal Reduction Amount, and the denominator of which is equal to the
then Stated Principal Balance of such Trust Mortgage Loan or REO Trust Mortgage
Loan, as the case may be. The existence of an Appraisal Reduction Amount with
respect to, or that is allocable to, any Trust Mortgage Loan or REO Trust
Mortgage Loan shall not affect the principal portion of any required P&I Advance
with respect thereto.

         For purposes of determining the amount of P&I Advances to be made with
respect to any Distribution Date, if an Appraisal Reduction Amount exists with
respect to the MGM Tower Loan Pair, then it shall be allocated: first, to the
MGM Tower Non-Trust Mortgage Loan (or any successor REO Mortgage Loan with
respect thereto), up to the amount of the then unpaid principal balance of such
Non-Trust Mortgage Loan (or any successor REO Mortgage Loan with respect
thereto), together with all accrued and unpaid interest thereon (exclusive of
any portion of such interest that constitutes Default Interest) to but not
including the most recent prior Due Date; and second, to the MGM Tower Trust
Mortgage Loan (or any successor REO Trust Mortgage Loan with respect thereto).
Also for purposes of determining the amount of P&I Advances to be made with
respect to any Distribution Date, if an Appraisal Reduction Amount exists with
respect to the GIC Office Loan Group, then it shall be allocated: first, to the
GIC Office Subordinate Non-Trust Mortgage Loan (or any successor REO Mortgage
Loan with respect thereto), up to the amount of the then unpaid principal
balance of such Non-Trust Mortgage Loan (or any successor REO Mortgage Loan with
respect thereto), together with all accrued and unpaid interest thereon
(exclusive of any portion of such interest that constitutes Default Interest) to
but not including the most recent prior Due Date; and second, to the GIC Office
Trust Mortgage Loan and the five GIC Office Pari Passu Non-Trust Mortgage Loans
(or any successor REO Trust Mortgage Loans with respect to the foregoing six
Mortgage Loans), on a pro rata basis in accordance with the respective then
unpaid principal balances of such six Mortgage Loans (or any successor REO
Mortgage Loans with respect thereto).

         (c) Notwithstanding anything herein to the contrary, no P&I Advance
shall be required to be made under this Section 4.03 if such P&I Advance would,
if made, constitute a Nonrecoverable P&I Advance. The Trustee and the Fiscal
Agent shall be entitled to rely, conclusively, on any determination by the
Master Servicer that a P&I Advance, if made pursuant to this Section 4.03, would
be a Nonrecoverable P&I Advance; provided, however, that if the Master Servicer
has failed to make a P&I Advance pursuant to this Section 4.03 for reasons other
than a determination by the Master Servicer that such P&I Advance would be a
Nonrecoverable P&I Advance or for the reasons contemplated by the following
paragraphs of this Section 4.03(c), the Trustee or Fiscal Agent shall make such
Advance within the time periods required by Section 4.03(a) unless the Trustee
or the Fiscal Agent, in its good faith, reasonable discretion, makes a
determination prior to the times specified in Section 4.03(a) that such P&I
Advance would be a Nonrecoverable P&I Advance. Upon determining that any P&I
Advance previously made or proposed to be made pursuant to this Section 4.03
with respect to a Specially Serviced Trust Mortgage Loan or any successor REO
Trust Mortgage Loan with respect thereto is or would, if made, constitute a
Nonrecoverable P&I Advance, the Special Servicer shall report to the Master
Servicer and the Trustee the Special Servicer's determination. Any determination
by the

                                     -241-
<PAGE>

Master Servicer or the Special Servicer that the Master Servicer has made a
Nonrecoverable P&I Advance pursuant to this Section 4.03, or that any proposed
P&I Advance, if made pursuant to this Section 4.03, would constitute a
Nonrecoverable P&I Advance, shall be evidenced by an Officer's Certificate
delivered to the Trustee, the Fiscal Agent and the Depositor on or before the
related Master Servicer Remittance Date, setting forth the basis for such
determination, together with any other information that supports such
determination, including an appraisal (which appraisal shall have been conducted
by an Independent Appraiser within the 12-month period preceding such
determination in accordance with the standards of the Appraisal Institute taking
into account the factors specified in Section 3.18), related Mortgagor operating
statements and financial statements, budgets and rent rolls of the related
Mortgaged Properties (to the extent available and/or in the Master Servicer's or
the Special Servicer's possession), engineers' reports, environmental surveys
and any similar reports that the Master Servicer may have obtained consistent
with the Servicing Standard and at the expense of the Trust Fund, that support
such determination by the Master Servicer or the Special Servicer, as
applicable. If, in connection with the foregoing, it is necessary for the Master
Servicer to obtain an appraisal, the Master Servicer shall so notify the Special
Servicer and consult with the Special Servicer regarding such appraisal. The
Master Servicer and the Trustee shall be entitled to conclusively rely on any
determination by the Special Servicer that an advance made or proposed to be
made pursuant to this Section 4.03 would be a Nonrecoverable Advance.

         If any of the GIC Office Pari Passu Non-Trust Mortgage Loans is
securitized as part of a rated commercial mortgage securitization similar to the
commercial mortgage securitization contemplated by this Agreement, and if the
Master Servicer receives written notice that the primary party responsible for
making delinquency advances similar to P&I Advances hereunder with respect to
such other commercial mortgage securitization has determined, in accordance with
the requirements of the related securitization agreement, that any such
delinquency advance made or to be made with respect to such securitized GIC
Office Pari Passu Non-Trust Mortgage Loan (or any successor REO Mortgage Loan
with respect thereto) would not ultimately be recoverable out of collections on
such GIC Office Pari Passu Non-Trust Mortgage Loan (or such REO Mortgage Loan),
then the Master Servicer shall deliver written notice to such effect to the
Trustee, the Fiscal Agent and the Depositor. In addition, it shall provide
notice to the Trustee, the Fiscal Agent and the Depositor if P&I Advances in
respect of the GIC Office Trust Mortgage Loan (or any successor REO Trust
Mortgage Loan with respect thereto) are no longer deemed Nonrecoverable P&I
Advances by virtue of the proviso to the definition of "Nonrecoverable P&I
Advance".

         In addition, if the Master Servicer has actual knowledge that any of
the GIC Office Pari Passu Non-Trust Mortgage Loans is securitized as part of a
rated commercial mortgage securitization similar to the commercial mortgage
securitization contemplated by this Agreement, and if the Master Servicer
determines that any P&I Advance made or to be made with respect to the GIC
Office Trust Mortgage Loan (or any successor REO Trust Mortgage Loan with
respect thereto) is or, if made, would be a Nonrecoverable P&I Advance, then the
Master Servicer shall, consistent with the GIC Office Co-Lender Agreement,
notify its counterpart under each such other commercial mortgage securitization
within one (1) Business Day of such determination. It will, consistent with the
GIC Office Co-Lender Agreement, also notify its counterpart under each such
other commercial mortgage securitization (within one (1) Business Day of such
determination) if it subsequently determines that P&I Advances made or to be
made with respect to the GIC Office Trust Mortgage Loan (or any successor REO
Trust Mortgage Loan with respect thereto) are no longer Nonrecoverable P&I
Advances. Following a determination of nonrecoverability by the Master Servicer
in accordance with this paragraph or by another party

                                     -242-
<PAGE>

responsible for making delinquency advances similar to P&I Advances with respect
to a GIC Office Pari Passu Non-Trust Mortgage Loan (or any successor REO
Mortgage Loan with respect thereto) in accordance with the preceding paragraph,
prior to the Master Servicer resuming P&I Advances with respect to the GIC
Office Trust Mortgage Loan (or any successor REO Trust Mortgage Loan with
respect thereto), the Master Servicer shall consult with its counterparts under
the securitizations of the GIC Office Pari Passu Non-Trust Mortgage Loans
regarding whether circumstances with respect to the subject mortgage loans have
changed such that a proposed future P&I Advance would not be a Nonrecoverable
P&I Advance.

         (d) The Master Servicer, the Trustee and the Fiscal Agent shall each be
entitled to receive interest at the Reimbursement Rate in effect from time to
time, compounded annually, accrued on the amount of each P&I Advance made
thereby under this Section 4.03 (with its own funds) for so long as such P&I
Advance is outstanding; provided that if the grace period for the delinquent
Monthly Payment as to which a P&I Advance was made under this Section 4.03 has
not elapsed as of the time such P&I Advance was made, then the total interest so
accrued on such P&I Advance prior to the expiration of such grace period, shall
not exceed the amount of Default Charges, if any, collected in connection with
the late payment of such delinquent Monthly Payment; and provided, further,
that, in no event shall interest so accrue on any P&I Advance as to which the
corresponding Late Collection was received by the Master Servicer or a
Sub-Servicer on its behalf as of the related Trust Master Servicer Remittance
Date. Interest so accrued on any P&I Advance made under this Section 4.03 shall
be payable: (i) first, in accordance with Sections 3.05(a) and 3.26, out of any
Default Charges on deposit in the Pool Custodial Account that were collected on
or in respect of the particular Trust Mortgage Loan or REO Trust Mortgage Loan
as to which the P&I Advance relates (provided that such Default Charges will
only be applied to pay interest accrued on such P&I Advance through the date
that such Default Charges were received); and (ii) then, if and to the extent
that such Default Charges are insufficient to cover such interest, but not
before the related Advance is being reimbursed or has been reimbursed pursuant
to this Agreement, out of general collections on the Mortgage Pool on deposit in
the Pool Custodial Account; provided that, if such P&I Advance was made with
respect to a Trust Mortgage Loan or REO Trust Mortgage Loan that is part of a
Loan Combination, then such interest on such P&I Advance shall first be payable
out of amounts on deposit in the related Loan Combination Custodial Account in
accordance with Section 3.05A or Section 3.05B, as applicable. The Master
Servicer shall, in accordance with Section 3.05(a), Section 3.05A and/or Section
3.05B, reimburse itself, the Trustee or the Fiscal Agent, as applicable, for any
outstanding P&I Advance made thereby under this Section 4.03 as soon as
practicable after funds available for such purpose are deposited in the
applicable Custodial Account. Notwithstanding the foregoing, upon a
determination that a previously made P&I Advance is a Nonrecoverable P&I
Advance, instead of obtaining reimbursement out of general collections on the
Mortgage Pool immediately, any of the Master Servicer, the Trustee or the Fiscal
Agent, as applicable, may, in its sole discretion, elect to obtain reimbursement
for such Nonrecoverable P&I Advance over a period of time (not to exceed 12
months or such longer period of time as is approved in writing by the
Controlling Class Representative) and the unreimbursed portion of such P&I
Advance will accrue interest at the Reimbursement Rate in effect from time to
time. At any time after such a determination to obtain reimbursement over time
in accordance with the preceding sentence, the Master Servicer, the Trustee or
the Fiscal Agent, as applicable, may, in its sole discretion, decide to obtain
reimbursement immediately. The fact that a decision to recover such
Nonrecoverable P&I Advance over time, or not to do so, benefits some Classes of
Certificateholders to the detriment of other Classes shall not constitute a
violation of the Servicing Standard by the Master Servicer or a breach of any
fiduciary duty owed to the

                                     -243-
<PAGE>

Certificateholders by the Trustee or the Fiscal Agent, or a breach of any other
contractual obligation owed to the Certificateholders by any party to this
Agreement.

         SECTION 4.04. Allocations of Realized Losses and Additional Trust Fund
                       Expenses

         (a) On each Distribution Date, following the distributions to
Certificateholders to be made on such date pursuant to Section 4.01 or 9.01, as
applicable, the Trustee shall determine the amount, if any, by which (i) the
then aggregate of the Class Principal Balances of all the Classes of Principal
Balance Certificates, exceeds (ii) the aggregate Stated Principal Balance of the
Mortgage Pool that will be outstanding immediately following such Distribution
Date. If such excess does exist, then the Class Principal Balances of the Class
T, Class S, Class Q, Class P, Class N, Class M, Class L, Class K, Class J, Class
H, Class G, Class F, Class E, Class D, Class C and Class B Certificates shall be
reduced sequentially, in that order, in each case, until such excess or the
related Class Principal Balance is reduced to zero (whichever occurs first). If,
after the foregoing reductions, the amount described in clause (i) of the second
preceding sentence still exceeds the amount described in clause (ii) of such
sentence, then the respective Class Principal Balances of all the outstanding
Classes of the Class A Certificates shall be reduced on a pro rata basis in
accordance with the relative sizes of such Class Principal Balances, until any
such remaining excess is reduced to zero. Any and all such reductions in the
Class Principal Balances of the respective Classes of the Principal Balance
Certificates pursuant to this Section 4.04(a) shall be deemed to constitute
allocations of Realized Losses and Additional Trust Fund Expenses.

         (b) If the Class Principal Balance of any Class of Principal Balance
Certificates is reduced on any Distribution Date pursuant to Section 4.04(a),
then the Uncertificated Principal Balance of such Class' Corresponding REMIC II
Regular Interest (or, if applicable, the aggregate Uncertificated Principal
Balance of such Class' Corresponding REMIC II Regular Interests) shall be deemed
to have first been reduced by the exact same amount. If a Class of Principal
Balance Certificates has two or more Corresponding REMIC II Regular Interests,
then the respective Uncertificated Principal Balances of such Corresponding
REMIC II Regular Interests shall be reduced as contemplated by the preceding
sentence in the same sequential order that principal distributions are deemed
made on such Corresponding REMIC II Regular Interests pursuant to Section
4.01(j), such that no reduction shall be made in the Uncertificated Principal
Balance of any such Corresponding REMIC II Regular Interest pursuant to this
Section 4.04(b) until the Uncertificated Principal Balance of each other such
Corresponding REMIC II Regular Interest, if any, with an alphanumeric
designation that ends in a lower number, has been reduced to zero. Any and all
such reductions in the Uncertificated Principal Balances of the respective REMIC
II Regular Interests (other than REMIC II Regular Interest X-ST) shall be deemed
to constitute allocations of Realized Losses and Additional Trust Fund Expenses.

         (c) On each Distribution Date, following the deemed distributions to be
made in respect of the REMIC I Regular Interests pursuant to Section 4.01(k),
the Uncertificated Principal Balance of each REMIC I Regular Interest (after
taking account of such deemed distributions) shall be reduced, if and to the
extent necessary, to equal the Stated Principal Balance of the related Trust
Mortgage Loan or REO Trust Mortgage Loan, as the case may be, that will be
outstanding immediately following such Distribution Date. Any and all such
reductions in the Uncertificated Principal Balances of the respective REMIC I
Regular Interests shall be deemed to constitute allocations of Realized Losses
and Additional Trust Fund Expenses.

         SECTION 4.05. Various Reinstatement Amounts.

         (a) On each Distribution Date, following the distributions to
Certificateholders to be made on such date pursuant to Section 4.01 or 9.01, as
applicable, the Trustee shall determine the amount, if any, by which (i) the
aggregate Stated Principal Balance of the Mortgage Pool that will be outstanding
immediately following such Distribution Date, exceeds (ii) the then aggregate of
the Class Principal Balances of all the Classes of Principal Balance
Certificates. If such an excess does exist, then the Trustee shall allocate the
Total Principal Reinstatement Amount, if any, for the subject Distribution Date
as follows until it is allocated in full: first, to all of the Classes of Class
A Certificates, up to, and on a pro rata basis in accordance with, the
respective Loss Reimbursement Amounts, if any, for such Classes of Class A
Certificates with respect to such Distribution Date (minus any amounts
reimbursed in respect of such respective Loss Reimbursement Amounts on the
subject Distribution Date pursuant to Section 4.01(a)); and then to the
remaining Classes of Principal Balance Certificates, sequentially in
alphabetical order based on the respective Class designations thereof, in each
case up to any Loss Reimbursement Amount for such Class of Principal Balance
Certificates with respect to such Distribution Date (minus any amount reimbursed
in respect of such Loss Reimbursement Amount on the subject Distribution Date
pursuant to Section 4.01(b)). Any portion of the Total Principal Reinstatement
Amount for any Distribution Date that is allocated to a particular Class of
Principal Balance Certificates shall be: (i) referred to herein as the "Class
Principal Reinstatement Amount" in respect of such Class of Principal Balance
Certificates for such Distribution Date; and (ii) added to the Class Principal
Balance of such Class of Principal Balance Certificates on such Distribution
Date. Notwithstanding anything to the contrary contained herein, the parties
hereby acknowledge that the reinstatement of all or any portion of the Class
Principal Balance of any Class of Principal Balance Certificates on any
Distribution Date shall be a result of the collection of Recovered Amounts
during the related Collection Period and the addition of such Recovered Amounts
to the Principal Distribution Amount for purposes of calculating the Adjusted
Principal Distribution Amount for such Distribution Date.

         (b) In connection with the reinstatement of all or any portion of the
Class Principal Balance of any one or more Classes of Principal Balance
Certificates on any Distribution Date, pursuant to Section 4.05(a), the Trustee
shall calculate the amount of lost Distributable Certificate Interest that would
have accrued on the respective Classes of Regular Interest Certificates through
and including the end of the Interest Accrual Period for such Distribution Date
if no reduction to the Class Principal Balance of any Class of Principal Balance
Certificates, pursuant to Section 4.04(a), had resulted on a prior Distribution
Date from the reimbursement out of general collections of principal on the
Mortgage Pool of the particular Advances (with interest thereon) that relate to
the Recovered Amounts associated with such reinstatement of outstanding
principal on the subject Distribution Date. Once determined, such lost
Distributable Certificate Interest in respect of any particular Class of Regular
Interest Certificates shall be reinstated and become due and payable on future
Distribution Dates as part of the unpaid Distributable Certificate Interest for
such Class of Regular Interest Certificates from prior Distribution Dates. All
such reinstated Distributable Certificate Interest in respect of any particular
Class of Regular Interest Certificates shall be treated the same as any other
unpaid Distributable Certificate Interest in respect of such Class of Regular
Interest Certificates.

         (c) If the Class Principal Balance of any Class of Principal Balance
Certificates is increased on any Distribution Date pursuant to Section 4.05(a),
then the Uncertificated Principal Balance of such Class' Corresponding REMIC II
Regular Interest (or, if applicable, the aggregate

                                     -245-
<PAGE>

Uncertificated Principal Balance of such Class' Corresponding REMIC II Regular
Interests) shall be deemed to have first been increased by the exact same
amount. In circumstances where there are multiple Corresponding REMIC II Regular
Interests with respect to a Class of Principal Balance Certificates, the
increases in the respective Uncertificated Principal Balances of such
Corresponding REMIC II Regular Interests as contemplated by the prior sentence
shall be made in the reverse order that reductions are made to such
Uncertificated Principal Balances pursuant to Section 4.04(b), in each case up
to the amount of the Loss Reimbursement Amount with respect to the subject REMIC
II Regular Interest for such Distribution Date (minus any amount reimbursed in
respect of such Loss Reimbursement Amount on the subject Distribution Date
pursuant to Section 4.01(j)).

         (d) If any lost Distributable Certificate Interest is reinstated with
respect to any Class of Regular Interest Certificates on any Distribution Date
pursuant to Section 4.05(b), then a corresponding amount of Uncertificated
Distributable Interest shall be reinstated with respect to such Class'
Corresponding REMIC II Regular Interest(s) (or, in the case of the Class X-CL or
Class X-CP Certificates, insofar as such lost Distributable Certificate Interest
corresponds to a particular REMIC III Component of such Class, a corresponding
amount of Uncertificated Distributable Interest shall be reinstated with respect
to such REMIC III Component's Corresponding REMIC II Regular Interest). In
circumstances where there are multiple Corresponding REMIC II Regular Interests
with respect to a Class of Principal Balance Certificates, the reinstatement of
such lost Uncertificated Distributable Interest with respect to such
Corresponding REMIC II Regular Interests as contemplated by the prior sentence
shall be effected taking into account the respective portions of such lost
Uncertificated Distributable Interest attributable to such Corresponding REMIC
II Regular Interests. Once reinstated, such lost Uncertificated Distributable
Interest in respect of any particular REMIC II Regular Interest shall become due
and payable on future Distribution Dates as part of the unpaid Uncertificated
Distributable Interest for such REMIC II Regular Interest from prior
Distribution Dates. All such reinstated Uncertificated Distributable Interest in
respect of any particular REMIC II Regular Interest shall be treated the same as
any other unpaid Uncertificated Distributable Interest in respect of such REMIC
II Regular Interest.

         SECTION 4.06. Calculations.

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

         SECTION 4.07. Use of Agents.

                  The Master Servicer, the Special Servicer or the Trustee may
at its own expense utilize agents or attorneys-in-fact in performing any of its
obligations under this Article IV (except the obligation to make P&I Advances),
but no such utilization shall relieve the Master Servicer, the Special

                                     -246-
<PAGE>

Servicer or the Trustee, as applicable, from any of such obligations, and the
Master Servicer, the Special Servicer or the Trustee, as applicable, shall
remain responsible for all acts and omissions of any such agent or
attorney-in-fact.

                                THE CERTIFICATES

         SECTION 5.01.   The Certificates.

         (a) The Certificates will be substantially in the respective forms
attached hereto as Exhibits A-1, A-2, A-3, A-4, A-5 and A-6; provided that any
of the Certificates may be issued with appropriate insertions, omissions,
substitutions and variations, and may have imprinted or otherwise reproduced
thereon such legend or legends, not inconsistent with the provisions of this
Agreement, as may be required to comply with any law or with rules or
regulations pursuant thereto, or with the rules of any securities market in
which the Certificates are admitted to trading, or to conform to general usage.
The Certificates will be issuable in registered form only; provided, however,
that in accordance with Section 5.03, beneficial ownership interests in the
Regular Interest Certificates shall initially be held and transferred through
the book-entry facilities of the Depository. The Regular Interest Certificates
will be issuable only in denominations corresponding to initial Certificate
Principal Balances or initial Certificate Notional Amounts, as the case may be,
as of the Closing Date of $10,000 in the case of the Class A-1, Class A-2, Class
A-3, Class A-4, Class B, Class C, Class D, Class E and Class F Certificates,
$250,000 in the case of the Interest-Only Certificates, and $250,000 in the case
of the remaining Regular Interest Certificates, and in each such case in
integral multiples of $1 in excess thereof. The Class R-I, Class R-II, Class
R-III and Class V Certificates will be issuable in denominations representing
Percentage Interests in the related Class of not less than 10%.

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

         SECTION 5.02. Registration of Transfer and Exchange of Certificates.

         (a) At all times during the term of this Agreement, there shall be
maintained at the office of the Certificate Registrar a Certificate Register in
which, subject to such reasonable regulations as the Certificate Registrar may
prescribe, the Certificate Registrar shall provide for the registration of
Certificates and of transfers and exchanges of Certificates as herein provided.
The Trustee is hereby initially appointed (and hereby agrees to act in
accordance with the terms hereof) as Certificate Registrar for the purpose of
registering Certificates and transfers and exchanges of Certificates as herein
provided. The offices of the Trustee responsible for its duties as initial
Certificate Register shall be located, as of the Closing Date, at 135 South
LaSalle, Suite 1625, Chicago, Illinois 60603, Attention: Asset-Backed Securities
Trust Services Group--LB-UBS Commercial Mortgage Trust, Series 2004-C1. The

Certificate Registrar may appoint, by a written instrument delivered to the
Depositor, the Master Servicer, the Special Servicer and (if the Trustee is not
the Certificate Registrar) the Trustee, any other bank or trust company to act
as Certificate Registrar under such conditions as the predecessor Certificate
Registrar may prescribe, provided that the predecessor Certificate Registrar
shall not be relieved of any of its duties or responsibilities hereunder by
reason of such appointment. If the Trustee resigns or is removed in accordance
with the terms hereof, the successor trustee shall immediately succeed to its
duties as Certificate Registrar. The Depositor, the Trustee (if it is no longer
the Certificate Registrar), the Master Servicer and the Special Servicer shall
have the right to inspect the Certificate Register or to obtain a copy thereof
at all reasonable times, and to rely conclusively upon a certificate of the
Certificate Registrar as to the information set forth in the Certificate
Register.

         If three or more Holders make written request to the Trustee, and such
request states that such Holders desire to communicate with other Holders with
respect to their rights under this Agreement or under the Certificates and is
accompanied by a copy of the communication which such Holders propose to
transmit, then the Trustee shall, within 30 days after the receipt of such
request, afford (or cause any other Certificate Registrar to afford) the
requesting Holders access during normal business hours to the most recent list
of Certificateholders held by the Certificate Registrar.

         (b) No Transfer of any Non-Registered Certificate or interest therein
shall be made unless that Transfer is exempt from the registration and/or
qualification requirements of the Securities Act and any applicable state
securities laws, or is otherwise made in accordance with the Securities Act and
such state securities laws.

         If a Transfer of any Definitive Non-Registered Certificate is to be
made without registration under the Securities Act (other than in connection
with the initial issuance of the Non-Registered Certificates or a Transfer of
such Certificate by the Depositor, Lehman Brothers or any of their respective
Affiliates or, in the case of a Global Certificate for any Class of Book-Entry
Non-Registered Certificates, a Transfer thereof to a successor Depository or to
the applicable Certificate Owner(s) in accordance with Section 5.03), then the
Certificate Registrar shall refuse to register such Transfer unless it receives
(and, upon receipt, may conclusively rely upon) either: (i) a certificate from
the Certificateholder desiring to effect such Transfer substantially in the form
attached hereto as Exhibit F-1 and a certificate from such Certificateholder's
prospective Transferee substantially in the form attached hereto either as
Exhibit F-2A or as Exhibit F-2B; or (ii) an Opinion of Counsel satisfactory to
the Trustee to the effect that the prospective Transferee is an Institutional
Accredited Investor or a Qualified Institutional Buyer and such Transfer may be
made without registration under the Securities Act (which Opinion of Counsel
shall not be an expense of the Trust Fund or of the Depositor, the Master
Servicer, the Special Servicer, the Tax Administrator, the Trustee, the Fiscal
Agent or the Certificate Registrar in their respective capacities as such),
together with the written certification(s) as to the facts surrounding such
Transfer from the Certificateholder desiring to effect such Transfer and/or such
Certificateholder's prospective Transferee on which such Opinion of Counsel is
based.

         If a Transfer of any interest in the Rule 144A Global Certificate for
any Class of Book-Entry Non-Registered Certificates is to be made without
registration under the Securities Act (other than in connection with the initial
issuance of the Book-Entry Non-Registered Certificates or a Transfer of any
interest therein by the Depositor, Lehman Brothers or any of their respective
Affiliates), then the Certificate Owner desiring to effect such Transfer shall
be required to obtain either (i) a certificate from such Certificate Owner's
prospective Transferee substantially in the form attached hereto as Exhibit
F-

                                     -249-
<PAGE>

2C, or (ii) an Opinion of Counsel to the effect that the prospective Transferee
is a Qualified Institutional Buyer and such Transfer may be made without
registration under the Securities Act. Except as provided in the following two
paragraphs, no interest in the Rule 144A Global Certificate for any Class of
Book-Entry Non-Registered Certificates shall be transferred to any Person who
takes delivery other than in the form of an interest in such Rule 144A Global
Certificate. If any Transferee of an interest in the Rule 144A Global
Certificate for any Class of Book-Entry Non-Registered Certificates does not, in
connection with the subject Transfer, deliver to the Transferor the Opinion of
Counsel or one of the certifications described in the preceding sentence, then
such Transferee shall be deemed to have represented and warranted that all the
certifications set forth in Exhibit F-2C hereto are, with respect to the subject
Transfer, true and correct. Further, as long as the Class T Certificates are
Book-Entry Certificates, any Certificate Owner desiring to effect a transfer of
a Class T Certificate or any interest therein may not sell or otherwise transfer
that Certificate or any interest therein unless it has provided the Depositor
with prior written notice of such transfer (together with a copy of the
certificate required pursuant to clause (i) above, executed by the proposed
transferee).

         Notwithstanding the preceding paragraph, any interest in the Rule 144A
Global Certificate for a Class of Book-Entry Non-Registered Certificates may be
transferred (without delivery of any certificate or Opinion of Counsel described
in clauses (i) and (ii) of the first sentence of the preceding paragraph) by the
Depositor or any Affiliate of the Depositor to any Person who takes delivery in
the form of a beneficial interest in the Regulation S Global Certificate for
such Class of Certificates upon delivery to the Certificate Registrar of (x) a
certificate to the effect that the Certificate Owner desiring to effect such
Transfer is the Depositor or an Affiliate of the Depositor and (y) such written
orders and instructions as are required under the applicable procedures of the
Depository, Clearstream and Euroclear to direct the Trustee, as transfer agent
for the Depository, to approve the debit of the account of a Depository
Participant by a denomination of interests in such Rule 144A Global Certificate,
and approve the credit of the account of a Depository Participant by a
denomination of interests in such Regulation S Global Certificate, that is equal
to the denomination of beneficial interests in the subject Class of Book-Entry
Non-Registered Certificates to be transferred. Upon delivery to the Certificate
Registrar of such certification and orders and instructions, the Trustee,
subject to and in accordance with the applicable procedures of the Depository,
shall reduce the denomination of the Rule 144A Global Certificate in respect of
the subject Class of Book-Entry Non-Registered Certificates, and increase the
denomination of the Regulation S Global Certificate for such Class of
Certificates, by the denomination of the beneficial interest in such Class of
Certificates specified in such orders and instructions.

         Also notwithstanding the foregoing, any interest in a Rule 144A Global
Certificate with respect to any Class of Book-Entry Non-Registered Certificates
may be transferred by any Certificate Owner holding such interest to any
Institutional Accredited Investor (other than a Qualified Institutional Buyer)
that takes delivery in the form of a Definitive Certificate of the same Class as
such Rule 144A Global Certificate upon delivery to the Certificate Registrar and
the Trustee of (i) such certifications and/or opinions as are contemplated by
the second paragraph of this Section 5.02(b) and (ii) such written orders and
instructions as are required under the applicable procedures of the Depository
to direct the Trustee to debit the account of a Depository Participant by the
denomination of the transferred interests in such Rule 144A Global Certificate.
Upon delivery to the Certificate Registrar of the certifications and/or opinions
contemplated by the second paragraph of this Section 5.02(b), the Trustee,
subject to and in accordance with the applicable procedures of the Depository,
shall reduce the denomination of the subject Rule 144A Global Certificate by the
denomination of the transferred interests in such Rule

                                     -250-
<PAGE>

144A Global Certificate, and shall cause a Definitive Certificate of the same
Class as such Rule 144A Global Certificate, and in a denomination equal to the
reduction in the denomination of such Rule 144A Global Certificate, to be
executed, authenticated and delivered in accordance with this Agreement to the
applicable Transferee.

         Except as provided in the next paragraph, no beneficial interest in the
Regulation S Global Certificate for any Class of Book-Entry Non-Registered
Certificates shall be transferred to any Person who takes delivery other than in
the form of a beneficial interest in such Regulation S Global Certificate. On
and prior to the Regulation S Release Date, the Certificate Owner desiring to
effect any such Transfer shall be required to obtain from such Certificate
Owner's prospective Transferee a written certification substantially in the form
set forth in Exhibit F-2D hereto certifying that such Transferee is not a United
States Securities Person. On or prior to the Regulation S Release Date,
beneficial interests in the Regulation S Global Certificate for each Class of
Book-Entry Non-Registered Certificates may be held only through Euroclear or
Clearstream. The Regulation S Global Certificate for each Class of Book-Entry
Non-Registered Certificates shall be deposited with the Trustee as custodian for
the Depository and registered in the name of Cede & Co. as nominee of the
Depository.

         Notwithstanding the preceding paragraph, after the Regulation S Release
Date, any interest in the Regulation S Global Certificate for a Class of
Book-Entry Non-Registered Certificates may be transferred by the Depositor or
any Affiliate of the Depositor to any Person who takes delivery in the form of a
beneficial interest in the Rule 144A Global Certificate for such Class of
Certificates upon delivery to the Certificate Registrar of (x) a certificate to
the effect that the Certificate Owner desiring to effect such Transfer is the
Depositor or an Affiliate of the Depositor and (y) such written orders and
instructions as are required under the applicable procedures of the Depository,
Clearstream and Euroclear to direct the Trustee to debit the account of a
Depository Participant by a denomination of interests in such Regulation S
Global Certificate, and credit the account of a Depository Participant by a
denomination of interests in such Rule 144A Global Certificate, that is equal to
the denomination of beneficial interests in the subject Class of Book-Entry
Non-Registered Certificates to be transferred. Upon delivery to the Certificate
Registrar of such certification and orders and instructions, the Trustee,
subject to and in accordance with the applicable procedures of the Depository,
shall reduce the denomination of the Regulation S Global Certificate in respect
of the subject Class of Book-Entry Non-Registered Certificates, and increase the
denomination of the Rule 144A Global Certificate for such Class of Certificates,
by the denomination of the beneficial interest in such Class of Certificates
specified in such orders and instructions.

         None of the Depositor, the Trustee or the Certificate Registrar is
obligated to register or qualify any Class of Non-Registered Certificates under
the Securities Act or any other securities law or to take any action not
otherwise required under this Agreement to permit the Transfer of any
Non-Registered Certificate or interest therein without registration or
qualification. Any Certificateholder or Certificate Owner desiring to effect a
Transfer of any Non-Registered Certificate or interest therein shall, and does
hereby agree to, indemnify the Depositor, the Underwriters, the Trustee, the
Fiscal Agent, the Master Servicer, the Special Servicer, the Tax Administrator
and the Certificate Registrar against any liability that may result if such
Transfer is not exempt from the registration and/or qualification requirements
of the Securities Act and any applicable state securities laws or is not made in
accordance with such federal and state laws.

investment funds and separate accounts in which such plans, accounts or
arrangements are invested, including insurance company general accounts, that is
subject to ERISA or the Code (each, a "Plan"), or (ii) to any Person who is
directly or indirectly purchasing such Certificate or interest therein on behalf
of, as named fiduciary of, as trustee of, or with assets of a Plan, if the
purchase and holding of such Certificate or interest therein by the prospective
Transferee would result in a violation of Section 406 or 407 of ERISA or Section
4975 of the Code or would result in the imposition of an excise tax under
Section 4975 of the Code. Furthermore, no Transfer of a Certificate or any
interest therein shall be made to any of the following (each, an "Ineligible
Purchaser"): (i) Howard L. Melamed or any other fiduciary with respect to the
Howard L. Melamed Profit Sharing Plan (the "Melamed Plan") ; (ii) a person
providing services to the Melamed Plan; (iii) employers who have any employees

the Non-Registered Certificates or any Transfer of a Non-Registered Certificate
or any interest therein by the Depositor, Lehman Brothers or any of their
respective Affiliates or, in the case of a Global Certificate for any Class of
Book-Entry Non-Registered Certificates, any Transfer thereof to a successor
Depository or to the applicable Certificate Owner(s) in accordance with Section
5.03, the Certificate Registrar shall refuse to register the Transfer of a
Definitive Non-Registered Certificate unless it has received from the
prospective Transferee, and any Certificate Owner transferring an interest in a
Global Certificate for any Class of Book-Entry Non-Registered Certificates shall
be required to obtain from its prospective Transferee, (x) a certification to
the effect that such prospective Transferee is not an Ineligible Purchaser and
is not directly or indirectly purchasing such Certificate or interest therein on
behalf of an Ineligible Purchaser and (y) one of the following: (i) a
certification to the effect that such prospective Transferee is not a Plan and
is not directly or indirectly purchasing such Certificate or interest therein on
behalf of, as named fiduciary of, as trustee of, or with assets of a Plan; or
(ii) alternatively, except in the case of a Residual Interest Certificate or a
Class V Certificate, a certification to the effect that the purchase and holding
of such Certificate or interest therein by such prospective Transferee is exempt
from the prohibited transaction provisions of Sections 406(a) and (b) and 407 of
ERISA and the excise taxes imposed on such prohibited transactions by Sections
4975(a) and (b) of the Code, by reason of Sections I and III of Prohibited
Transaction Class Exemption 95-60; or (iii) alternatively, but only in the case

agrees that it will obtain from each of its Transferees that are Plans a written
representation that such

<PAGE>

Transferee, if a Plan, satisfied the requirements of the immediately preceding
clauses (iii)(X) and (iii)(Y), together with a written agreement that such
Transferee will obtain from each of its Transferees that are Plans a similar
written representation regarding satisfaction of the requirements of the
immediately preceding clauses (iii)(X) and (iii)(Y); or (iv) alternatively, a
certification of facts and an Opinion of Counsel which otherwise establish to
the reasonable satisfaction of the Trustee or such Certificate Owner, as the
case may be, that such Transfer will not result in a violation of Section 406 or
407 of ERISA or Section 4975 of the Code or result in the imposition of an
excise tax under Section 4975 of the Code. It is hereby acknowledged that the
forms of certification attached hereto as Exhibit G-1 (in the case of Definitive
Non-Registered Certificates) and Exhibit G-2 (in the case of ownership interests
in Book-Entry Non-Registered Certificates) are acceptable for purposes of the
preceding sentence. If any Transferee of a Certificate (including a Registered

Transfer, deliver to the Certificate Registrar (in the case of a Definitive
Certificate) or the Transferor (in the case of ownership interests in a
Book-Entry Certificate) any certification and/or Opinion of Counsel contemplated
by the second preceding sentence, then such Transferee shall be deemed to have

Purchaser and (B) either: (i) such Transferee is not a Plan and is not directly
or indirectly purchasing such Certificate or interest therein on behalf of, as
named fiduciary of, as trustee of, or with assets of a Plan; or (ii) the
purchase and holding of such Certificate or interest therein by such Transferee
is exempt from the prohibited transaction provisions of Sections 406(a) and (b)
and 407 of ERISA and the excise taxes imposed on such prohibited transactions by
Sections 4975(a) and (b) of the Code. Any acquisition or holding of a
Certificate by an Ineligible Purchaser shall be void ab initio and of no force
and effect.

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

                           (A)      Each Person holding or acquiring any
                                    Ownership Interest in a Residual Interest
                                    Certificate shall be a Permitted Transferee
                                    and shall promptly notify the Tax

                                    or impending change in its status as a
                                    Permitted Transferee.

                           (B)      In connection with any proposed Transfer of
                                    any Ownership Interest in a Residual
                                    Interest Certificate, the Certificate
                                    Registrar shall require delivery to it, and
                                    shall not register the Transfer of any
                                    Residual Interest Certificate until its

                                    Transferee, that it is not acquiring its

                                    has reviewed the provisions of this Section
                                    5.02(d) and agrees to be bound by them.

                           (C)      Notwithstanding the delivery of a Transfer
                                    Affidavit and Agreement by a proposed

                                    the Certificate Registrar has actual
                                    knowledge that the proposed Transferee is
                                    not a Permitted Transferee, no Transfer of

                                    shall be effected.

                           (D)      Each Person holding or acquiring any
                                    Ownership Interest in a Residual Interest
                                    Certificate shall agree (1) to require a

                                    it provides to the Certificate Registrar a
                                    certificate substantially in the form
                                    attached hereto as Exhibit H-2 stating that,
                                    among other things, it has no actual
                                    knowledge that such prospective Transferee
                                    is not a Permitted Transferee.

                           (E)      Each Person holding or acquiring an
                                    Ownership Interest in a Residual Interest
                                    Certificate, by purchasing such Ownership
                                    Interest, agrees to give the Tax
                                    Administrator and the Trustee written notice
                                    that it is a "pass-through interest holder"
                                    within the meaning of temporary Treasury
                                    regulations section 1.67-3T(a)(2)(i)(A)
                                    immediately upon acquiring an Ownership
                                    Interest in a Residual Interest Certificate,
                                    if it is, or is holding an Ownership
                                    Interest in a Residual Interest Certificate
                                    on behalf of, a "pass-through interest
                                    holder".

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

                  (B)      If any purported Transferee shall become a Holder of
                           a Residual Interest Certificate in violation of the
                           restrictions in this Section 5.02(d), then, to the
                           extent that retroactive restoration of the rights of
                           the preceding Holder of such Residual Interest
                           Certificate as described in clause (ii)(A) above
                           shall be invalid, illegal or unenforceable, the
                           Trustee shall have the right but not the obligation,
                           to

                                     -254-

                           cause the Transfer of such Residual Interest
                           Certificate to a Permitted Transferee selected by the
                           Trustee on such terms as the Trustee may choose, and
                           the Trustee shall not be liable to any Person having
                           an Ownership Interest in such Residual Interest
                           Certificate as a result of the Trustee's exercise of
                           such discretion. Such purported Transferee shall
                           promptly endorse and deliver such Residual Interest
                           Certificate in accordance with the instructions of
                           the Trustee. Such Permitted Transferee may be the
                           Trustee itself or any Affiliate of the Trustee.

                  (iii) The Tax Administrator shall make available to the IRS
         and to those Persons specified by the REMIC Provisions all information
         furnished to it by the other parties hereto necessary to compute any
         tax imposed (A) as a result of the Transfer of an Ownership Interest in
         a Residual Interest 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 Interest 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 Interest Certificate having as among its record holders
         at any time any Person which is a Disqualified Organization, and each
         of the other parties hereto shall furnish to the Tax Administrator all
         information in its possession necessary for the Tax Administrator to
         discharge such obligation. The Person holding such Ownership Interest
         shall be responsible for the reasonable compensation of the Tax
         Administrator for providing information thereto pursuant to this
         subsection (d)(iii) and Section 10.01(h)(i).

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

                           (A)      written confirmation from each Rating Agency
                                    to the effect that the modification of,
                                    addition to or elimination of such
                                    provisions will not cause an Adverse Rating
                                    Event with respect to any Class of
                                    Certificates; and

                           (B)      an Opinion of Counsel, in form and substance
                                    satisfactory to the Trustee and the Tax
                                    Administrator, obtained at the expense of
                                    the party seeking such modification of,
                                    addition to or elimination of such
                                    provisions (but in no event at the expense
                                    of the Trustee, the Tax Administrator or the
                                    Trust), to the effect that doing so will not
                                    (1) cause any REMIC Pool to cease to qualify
                                    as a REMIC or be subject to an entity-level
                                    tax caused by the Transfer of any Residual
                                    Interest Certificate to a Person which is
                                    not a Permitted Transferee or (2) cause a
                                    Person other than the prospective Transferee
                                    to be subject to a REMIC-related tax caused
                                    by the Transfer of a Residual Interest
                                    Certificate to a Person that is not a
                                    Permitted Transferee.

         (e) If a Person is acquiring any Non-Registered Certificate or interest
therein as a fiduciary or agent for one or more accounts, such Person shall be
required to deliver to the Certificate Registrar (or, in the case of an interest
in a Book-Entry Non-Registered Certificate, to the Certificate

                                     -255-
<PAGE>

Owner that is transferring such interest) a certification to the effect that,
and such other evidence as may be reasonably required by the Trustee (or such
Certificate Owner) to confirm that, it has (i) sole investment discretion with
respect to each such account and (ii) full power to make the applicable
foregoing acknowledgments, representations, warranties, certifications and
agreements with respect to each such account as set forth in subsections (b),
(c) and/or (d), as appropriate, of this Section 5.02.

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

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

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

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

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

         SECTION 5.03. Book-Entry Certificates.

         (a) Each Class of Regular Interest Certificates shall initially be
issued as one or more Certificates registered in the name of the Depository or
its nominee and, except as provided in Section 5.03(c) and in the fifth
paragraph of Section 5.02(b), a Transfer of such Certificates may not be
registered by the Certificate Registrar unless such Transfer is to a successor
Depository that agrees to hold such Certificates for the respective Certificate
Owners with Ownership Interests therein. Such Certificate Owners shall hold and
Transfer their respective Ownership Interests in and to such Certificates
through the book-entry facilities of the Depository and, except as provided in
Section 5.03(c) and in the fifth paragraph of Section 5.02(b), shall not be
entitled to definitive, fully registered Certificates ("Definitive
Certificates") in respect of such Ownership Interests. The Class X-CL, Class
X-CP, Class X-ST, Class G, Class H, Class J, Class K, Class L, Class M, Class N,
Class P, Class Q, Class S and Class T Certificates initially sold to Qualified
Institutional Buyers in reliance on Rule 144A or in reliance on another
exemption from the registration requirements of the Securities Act shall, in the
case of each such Class, be represented by the Rule 144A Global Certificate for
such Class, which shall be deposited with the Trustee as custodian for the
Depository and registered in the name of

                                     -256-
<PAGE>

Cede & Co. as nominee of the Depository. The Class X-CL, Class X-CP, Class X-ST,
Class G, Class H, Class J, Class K, Class L, Class M, Class N, Class P, Class Q,
Class S and Class T Certificates initially sold in offshore transactions in
reliance on Regulation S shall, in the case of each such Class, be represented
by the Regulation S Global Certificate for such Class, which shall be deposited
with the Trustee as custodian for the Depository and registered in the name of
Cede & Co. as nominee of the Depository. All Transfers by Certificate Owners of
their respective Ownership Interests in the Book-Entry Certificates shall be
made in accordance with the procedures established by the Depository Participant
or brokerage firm representing each such Certificate Owner. Each Depository
Participant shall only transfer the Ownership Interests in the Book-Entry
Certificates of Certificate Owners it represents or of brokerage firms for which
it acts as agent in accordance with the Depository's normal procedures.

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

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

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

         (d) Notwithstanding any other provisions contained herein, neither the
Trustee nor the Certificate Registrar shall have any responsibility whatsoever
to monitor or restrict the Transfer of

                                     -257-
<PAGE>

ownership interests in any Certificate (including but not limited to any
Non-Registered Certificate or any Subordinate Certificate) which interests are
transferable through the book-entry facilities of the Depository.

         SECTION 5.04. Mutilated, Destroyed, Lost or Stolen Certificates.

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

         SECTION 5.05. Persons Deemed Owners.

         Prior to due presentment for registration of transfer, the Depositor,
the Master Servicer, the Special Servicer, the Trustee, the Certificate
Registrar and any agent of any of them may treat the Person in whose name any
Certificate is registered as 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 Master Servicer, the Special Servicer,
the Trustee, the Certificate Registrar or any agent of any of them shall be
affected by notice to the contrary.

                                   ARTICLE VI

            THE DEPOSITOR, THE MASTER SERVICER, THE SPECIAL SERVICER
                    AND THE CONTROLLING CLASS REPRESENTATIVE

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

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

         SECTION 6.02. Continued Qualification and Compliance of Master
                       Servicer; Merger, Consolidation or Conversion of
                       Depositor, Master Servicer or Special Servicer.

         Subject to the following paragraph, the Depositor, the Master Servicer
and the Special Servicer shall each keep in full effect its existence, rights
and franchises as a legal entity under the laws of the jurisdiction of its
organization, and each will obtain and preserve its qualification to do business
as a foreign entity in, and will otherwise remain in compliance with the laws
of, each jurisdiction in which such qualification and compliance 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.

         Each of the Depositor, the Master Servicer and the Special Servicer may
be merged or consolidated with or into any Person, or transfer all or
substantially all of its assets (which, in the case of the Master Servicer or
the Special Servicer, may be limited to all or substantially all of its assets
related to commercial mortgage loan servicing) to any Person, in which case any
Person resulting from any merger or consolidation to which the Depositor, the
Master Servicer or the Special Servicer shall be a party, or any Person
succeeding to the business (which, in the case of the Master Servicer or the
Special Servicer, may be limited to the commercial mortgage loan servicing
business) of the Depositor, the Master Servicer or the Special Servicer, shall
be the successor of the Depositor, the Master Servicer or the Special Servicer,
as the case may be, hereunder, without the execution or filing of any paper or
any further act on the part of any of the parties hereto, anything herein to the
contrary notwithstanding; provided, however, that no successor or surviving
Person shall succeed to the rights of the Master Servicer or the Special
Servicer unless (i) as confirmed in writing by each of the Rating Agencies, such
succession will not result in an Adverse Rating Event with respect to any Class
of Certificates or any class of GIC Office Pari Passu Non-Trust Mortgage
Securities rated by such Rating Agency, and (ii) such successor or surviving
Person makes the applicable representations and warranties set forth in Section
3.23 (in the case of a successor or surviving Person to the Master Servicer) or
Section 3.24 (in the case of a successor or surviving Person to the Special
Servicer), as applicable.

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

         None of the Depositor, the Master Servicer or the Special Servicer
shall be under any liability to the Trust Fund, the Trustee, the
Certificateholders or the Non-Trust Mortgage Loan Noteholders for any action
taken, or not taken, in good faith pursuant to this Agreement, or for errors in

                                     -259-
<PAGE>

judgment; provided, however, that this provision shall not protect the
Depositor, the Master Servicer or the Special Servicer against any liability to
the Trust Fund, the Trustee, the Certificateholders or the Non-Trust Mortgage
Loan Noteholders for the breach of a representation or warranty made herein by
such party, or against any expense or liability specifically required to be
borne by such party without right of reimbursement pursuant to the terms hereof,
or against any liability which would otherwise be imposed by reason of willful
misfeasance, bad faith or negligence in the performance of its obligations or
duties hereunder or negligent disregard of such obligations or duties. The
Depositor, the Master Servicer, the Special Servicer and any director, manager,
member, officer, employee or agent of the Depositor, the Master Servicer or the
Special Servicer may rely in good faith on any document of any kind which, prima
facie, is properly executed and submitted by any Person respecting any matters
arising hereunder. The Depositor, the Master Servicer, the Special Servicer and
any director, manager, member, officer, employee or agent of the Depositor, the
Master Servicer or the Special Servicer shall be indemnified and held harmless
by the Trust Fund out of the Pool Custodial Account against any loss, liability
or reasonable expense (including reasonable legal fees and expenses) incurred in
connection with any legal action or claim relating to this Agreement or the
Certificates (including in connection with the dissemination of information and
reports as contemplated by this Agreement), other than any such loss, liability
or expense: (i) specifically required to be borne by the party seeking
indemnification, without right of reimbursement pursuant to the terms hereof;
(ii) which constitutes a Servicing Advance that is otherwise reimbursable
hereunder; (iii) incurred in connection with any legal action or claim against
the party seeking indemnification, resulting from any breach on the part of that
party of a representation or warranty made herein; or (iv) incurred in
connection with any legal action or claim against the party seeking
indemnification, resulting from any willful misfeasance, bad faith or negligence
on the part of that party in the performance of its obligations or duties
hereunder or negligent disregard of such obligations or duties; provided that if
a Loan Combination is involved, such indemnity shall be payable out of the
related Loan Combination Custodial Account pursuant to Section 3.05A or Section
3.05B, as applicable, and, if and to the extent not solely attributable to one
or more Non-Trust Mortgage Loans (or any successor REO Mortgage Loan(s) with
respect thereto), shall also be payable out of the Pool Custodial Account if
amounts on deposit in the related Loan Combination Custodial Account(s) are
insufficient therefor. None of the Depositor, the Master Servicer or the Special
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 either (i) it is specifically required hereunder to bear the costs
of such action or (ii) such action will not, in its reasonable and good faith
judgment, involve it in any ultimate expense or liability for which it would not
be reimbursed hereunder. Notwithstanding the foregoing, the Depositor, the
Master Servicer or the Special Servicer may in its discretion undertake any such
action which it may deem necessary or desirable with respect to the enforcement
and/or protection of the rights and duties of the parties hereto and the
interests of the Certificateholders (or, if a Loan Combination is affected, the
rights of the Certificateholders and the related Non-Trust Mortgage Loan
Noteholder(s) (as a collective whole)). In such event, the legal expenses and
costs of such action, and any liability resulting therefrom, shall be expenses,
costs and liabilities of the Trust Fund, and the Depositor, the Master Servicer
and the Special Servicer shall be entitled to be reimbursed therefor from the
Pool Custodial Account as provided in Section 3.05(a); provided, however, that
if and to the extent a Loan Combination and/or a Non-Trust Mortgage Loan
Noteholder is involved, such expenses, costs and liabilities shall be payable
out of the related Loan Combination Custodial Account pursuant to Section 3.05A
or Section 3.05B, as applicable, and, if and to the extent attributable to one
or more Trust Mortgage Loans and/or REO Trust Mortgage Loans, shall also be
payable out of the Pool Custodial Account if amounts on deposit in the related
Loan Combination Custodial Account(s) are insufficient therefor. In no event
shall the Master Servicer or the

                                     -260-
<PAGE>

Special Servicer be liable or responsible for any action taken or omitted to be
taken by the other of them (unless they are the same Person or Affiliates) or
for any action taken or omitted to be taken by the Depositor, the Trustee, any
Certificateholder or any Non-Trust Mortgage Loan Noteholder (unless they are the
same Person or Affiliates).

         SECTION 6.04. Resignation of Master Servicer and the Special Servicer.

         (a) The Master Servicer and, subject to Section 6.09, the Special
Servicer may each resign from the obligations and duties hereby imposed on it,
upon a determination that its duties hereunder are no longer permissible under
applicable law or are in material conflict by reason of applicable law with any
other activities carried on by it (the other activities of the Master Servicer
or the Special Servicer, as the case may be, so causing such a conflict being of
a type and nature carried on by the Master Servicer or the Special Servicer, as
the case may be, at the date of this Agreement). Any such determination
requiring the resignation of the Master Servicer or the Special Servicer, as
applicable, shall be evidenced by an Opinion of Counsel to such effect which
shall be delivered to the Trustee. Unless applicable law requires the Master
Servicer's or Special Servicer's resignation to be effective immediately, and
the Opinion of Counsel delivered pursuant to the prior sentence so states, no
such resignation shall become effective until the Trustee or other successor
shall have assumed the responsibilities and obligations of the resigning party
in accordance with Section 6.09 or Section 7.02 hereof. The Master Servicer and,
subject to the rights of the Controlling Class under Section 6.09 to appoint a
successor special servicer, the Special Servicer shall each have the right to
resign at any other time, provided that (i) a willing successor thereto
reasonably acceptable to the Depositor has been found (provided that if the
Depositor has not responded to a request for consent to a successor within 15
days, such successor shall be deemed approved thereby), (ii) each Rating Agency
confirms in writing that the successor's appointment will not result in an
Adverse Rating Event with respect to any Class of Certificates or any class of
GIC Office Pari Passu Non-Trust Mortgage Securities rated by such Rating Agency,
(iii) the resigning party pays all costs and expenses in connection with such
resignation and the resulting transfer of servicing, and (iv) the successor
accepts appointment prior to the effectiveness of such resignation and agrees in
writing to be bound by the terms and conditions of this Agreement. Neither the
Master Servicer nor the Special Servicer shall be permitted to resign except as
contemplated above in this Section 6.04(a).

         (b) Consistent with Section 6.04(a), neither the Master Servicer nor
the Special Servicer shall, except as expressly provided herein, assign or
transfer any of its rights, benefits or privileges hereunder to any other Person
or, except as provided in Sections 3.22, 4.06, 7.01(c) and 7.01(d), delegate to
or subcontract with, or authorize or appoint any other Person to perform any of
the duties, covenants or obligations to be performed by it hereunder. If,
pursuant to any provision hereof, the duties of the Master Servicer or the
Special Servicer are transferred to a successor thereto, the Master Servicing
Fee, the Special Servicing Fee, any Workout Fee (except as expressly
contemplated by Section 3.11(c)) and/or any Liquidation Fee, as applicable, that
accrues or otherwise becomes payable pursuant hereto from and after the date of
such transfer shall be payable to such successor.

         SECTION 6.05. Rights of Depositor, Trustee and Non-Trust Mortgage Loan
                       Noteholders in Respect of the Master Servicer and the
                       Special Servicer.

         The Master Servicer and the Special Servicer shall each afford the
Depositor, each Underwriter, the Trustee and each Non-Trust Mortgage Loan
Noteholder, upon reasonable notice, during normal business hours access to all
records maintained thereby in respect of its rights and obligations hereunder.
Upon reasonable request, the Master Servicer and the Special Servicer shall each
furnish the Depositor, each Underwriter, the Trustee and each Non-Trust Mortgage
Loan Noteholder with its most recent publicly available financial statements and
such other non-proprietary information as the Master Servicer or the Special
Servicer, as the case may be, shall determine in its sole and absolute
discretion as it possesses, which is relevant to the performance of its duties
hereunder and which it is not prohibited by applicable law or contract from
disclosing. The Depositor may, but is not obligated to, enforce the obligations
of the Master Servicer and the Special Servicer hereunder and may, but is not
obligated to, perform, or cause a designee to perform, any defaulted obligation
of the Master Servicer or Special Servicer hereunder or exercise the rights of
the Master Servicer and the Special Servicer hereunder; provided, however, that
neither the Master Servicer nor the Special Servicer shall be relieved of any of
its obligations hereunder by virtue of such performance by the Depositor or its
designee and, provided, further, that the Depositor may not exercise any right
pursuant to Section 7.01 to terminate the Master Servicer or the Special
Servicer as a party to this Agreement. The Depositor shall not have any
responsibility or liability for any action or failure to act by the Master
Servicer or the Special Servicer and is not obligated to supervise the
performance of the Master Servicer or the Special Servicer under this Agreement
or otherwise.

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

         The Depositor, the Master Servicer and the Special Servicer shall each
furnish such reports, certifications and information as are reasonably requested
by the Trustee in order to enable it to perform its duties hereunder.

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

         The Depositor, the Special Servicer and the Trustee shall each furnish
such reports, certifications and information as are reasonably requested by the
Master Servicer in order to enable it to perform its duties hereunder.

         SECTION 6.08. Depositor, Master Servicer and Trustee to Cooperate with
                       Special Servicer.

         The Depositor, the Master Servicer and the Trustee shall each furnish
such reports, certifications and information as are reasonably requested by the
Special Servicer in order to enable it to perform its duties hereunder.

         SECTION 6.09. Designation of Special Servicer and Controlling Class
                       Representative by the Controlling Class.

         (a) The Holder or Holders of the Certificates evidencing a majority of
the Voting Rights allocated to the Controlling Class may at any time and from
time to time designate a Person to serve as Special Servicer hereunder and to
replace any existing Special Servicer or any Special Servicer that has resigned
or otherwise ceased to serve (including in connection with a termination
pursuant to Section 7.01) as Special Servicer. Such Holder or Holders shall so
designate a Person to serve as replacement Special Servicer by the delivery to
the Trustee, the Master Servicer, each Non-Trust Mortgage Loan Noteholder and
the existing Special Servicer of a written notice stating such designation. The
Trustee shall, promptly after receiving any such notice, deliver to the Rating
Agencies an executed Notice and Acknowledgment in the form attached hereto as
Exhibit I-1. If such Holders have not replaced the Special Servicer within 30
days of such Special Servicer's resignation or the date such Special Servicer
has ceased to serve in such capacity, the Trustee shall designate a successor
Special Servicer, subject to removal by the Controlling Class and appointment of
a successor thereto pursuant to the terms of this Section 6.09. Any designated
Person (whether designated by Holders of the Controlling Class or by the
Trustee) shall become the Special Servicer on the date as of which the Trustee
shall have received all of the following: (1) written confirmation from each
Rating Agency that the appointment of such Person will not result in an Adverse
Rating Event with respect to any Class of Certificates or any class of GIC
Office Pari Passu Non-Trust Mortgage Securities rated by such Rating Agency; (2)
an Acknowledgment of Proposed Special Servicer in the form attached hereto as
Exhibit I-2, executed by the designated Person; and (3) an Opinion of Counsel
(at the expense of the Person designated to become the Special Servicer) to the
effect that, upon the execution and delivery of the Acknowledgment of Proposed
Special Servicer, the designated Person shall be bound by the terms of this
Agreement and, subject to customary limitations, that this Agreement shall be
enforceable against the designated Person in accordance with its terms. Any
existing Special Servicer shall be deemed to have resigned simultaneously with
such designated Person's becoming the Special Servicer hereunder; provided,
however, that (i) the outgoing Special Servicer shall continue to be entitled to
receive all amounts accrued or owing to it under this Agreement on or prior to
the effective date of such resignation, whether in respect of Servicing Advances
or otherwise, (ii) if the outgoing Special Servicer was terminated without
cause, it shall be entitled to a portion of certain Workout Fees thereafter
payable with respect to the Corrected Mortgage Loans (but only if and to the
extent permitted by Section 3.11(c)) and (iii) the outgoing Special Servicer
shall continue to be entitled to the benefits of Section 6.03 notwithstanding
any such resignation. The outgoing Special Servicer shall cooperate with the
Trustee and the replacement Special Servicer in effecting the termination of the
outgoing Special Servicer's responsibilities and rights hereunder, including the
transfer within two (2) Business Days to the replacement Special Servicer for
administration by it of all cash amounts that shall at the time be or should
have been credited by the Special Servicer to a Custodial Account, a Servicing
Account, a Reserve Account or an REO Account or should have been delivered to
the Master Servicer or that are thereafter received with respect to Specially
Serviced Mortgage Loans and REO Properties. The Trustee shall notify the other
parties hereto, the Certificateholders and the Non-Trust Mortgage Loan
Noteholders of any termination of the Special Servicer and appointment of a new
Special Servicer in accordance with this Section 6.09.

         Any out-of-pocket costs and expenses incurred in connection with the
removal (without cause) of a Special Servicer pursuant to this Section 6.09 and
its replacement by a Person designated by the Holder or Holders of Certificates
evidencing a majority of the Voting Rights allocated to the

                                     -263-
<PAGE>

Controlling Class, that are not paid by the replacement Special Servicer shall
be paid by such Holder or Holders. The rights of the Controlling Class
Certificateholders are subject to the consultation rights of the GIC Office
Subordinate Non-Trust Mortgage Loan Noteholder and the MGM Tower Non-Trust
Mortgage Loan Noteholder, in each case set forth in Section 3.02 of the related
Co-Lender Agreement, regarding successor special servicers with respect to the
GIC Office Loan Group and the MGM Tower Loan Pair, respectively.

         (b) The Holder or Holders of the Certificates evidencing a majority of
the Voting Rights allocated to the Controlling Class may also select a
representative (the "Controlling Class Representative") from whom the Special
Servicer will seek advice and approval and take direction under certain
circumstances, as described herein, and shall promptly notify the Trustee, the
Master Servicer and the Special Servicer of that selection. Notwithstanding the
foregoing, until a Controlling Class Representative is so selected in accordance
with the preceding sentence, or after receipt of a notice from the Holder or
Holders evidencing a majority of the Voting Rights allocated to the Controlling
Class that a Controlling Class Representative is no longer designated, the
Certificateholder, if any, that beneficially owns more than 50% of the aggregate
principal balance of the Controlling Class Certificates will be deemed to be the
Controlling Class Representative; provided that, if the Certificates of the
Controlling Class consist of Book-Entry Certificates, then any costs or expenses
incurred in connection with determining the identity of the Controlling Class
Representative shall be paid by the Trust or, if paid by the Trustee, reimbursed
to the Trustee out of the Trust Fund (in any event, out of amounts otherwise
payable with respect to the Controlling Class of Certificates). The Controlling
Class Representative shall be required to keep all non-public information
received by it in such capacity pursuant to this Agreement confidential and,
upon its designation as such, the Controlling Class Representative (except with
respect to the initial Controlling Class Representative as provided in the
following sentence) shall deliver to the Trustee, the Master Servicer and the
Special Servicer a written confirmation to such effect, in the form of Exhibit O
attached hereto. Upon its acquisition of all the Class T Certificates, Allied
Capital Corporation shall be the initial Controlling Class Representative, and
by its acceptance of such designation, shall be deemed to have agreed to keep
all non-public information received by it in such capacity from time to time
pursuant to this Agreement confidential, subject to applicable law.

         (c) Notwithstanding the foregoing, if the Certificates of the
Controlling Class consist of Book-Entry Certificates, then the rights of the
Holders of the Certificates of the Controlling Class set forth above in this
Section 6.09 may be exercised directly by the relevant Certificate Owner(s),
provided that the identity of such Certificate Owner(s) has been confirmed to
the Trustee to its reasonable satisfaction. If the Certificates of the
Controlling Class consist of Book-Entry Certificates, then any costs or expenses
incurred in connection with determining the identity of the Controlling Class
Representative shall be paid by the Trust or, if paid by the Trustee, reimbursed
to the Trustee out of the Trust Fund (in any event, out of amounts otherwise
payable with respect to the Controlling Class of Certificates).

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

         The Master Servicer, the Special Servicer or any Affiliate of either of
them may become the Holder of (or, in the case of a Book-Entry Certificate,
Certificate Owner with respect to) any Certificate with (except as otherwise set
forth in the definition of "Certificateholder") the same rights it would have if
it were not the Master Servicer or the Special Servicer or an Affiliate thereof.
If, at any time during which the Master Servicer or the Special Servicer or an
Affiliate of the Master Servicer or

                                     -264-
<PAGE>

the Special Servicer is the Holder of (or, in the case of a Book-Entry
Certificate, Certificate Owner with respect to) any Certificate, the Master
Servicer or the Special Servicer proposes to take action (including for this
purpose, omitting to take action) that is not expressly prohibited by the terms
hereof and would not, in the Master Servicer's or the Special Servicer's
reasonable, good faith judgment, violate the Servicing Standard, but that, if
taken, might nonetheless, in the Master Servicer's or the Special Servicer's
good faith judgment, be considered by other Persons to violate the Servicing
Standard, then the Master Servicer or the Special Servicer may (but need not)
seek the approval of the Certificateholders to such action by delivering to the
Trustee a written notice that (a) states that it is delivered pursuant to this
Section 6.10, (b) identifies the Percentage Interest in each Class of
Certificates beneficially owned by the Master Servicer or an Affiliate thereof
or the Special Servicer or an Affiliate thereof, as appropriate, and (c)
describes in reasonable detail the action that the Master Servicer or the
Special Servicer proposes to take. The Trustee, upon receipt of such notice,
shall forward it to the Certificateholders (other than the Master Servicer and
its Affiliates or the Special Servicer and its Affiliates, as appropriate),
together with such instructions for response as the Trustee shall reasonably
determine. If at any time Certificateholders holding greater than 50% of the
Voting Rights of all Certificateholders (calculated without regard to the
Certificates beneficially owned by the Master Servicer or its Affiliates or the
Special Servicer or its Affiliates, as appropriate) shall have failed to object
in writing (with a copy to the related Non-Trust Mortgage Loan Noteholder(s), if
a Loan Combination is involved) to the proposal described in the written notice,
and if the Master Servicer or the Special Servicer shall act as proposed in the
written notice within 30 days, such action shall be deemed to comply with, but
not modify, the Servicing Standard. The Trustee shall be entitled to
reimbursement from the Master Servicer or the Special Servicer, as applicable,
for the reasonable expenses of the Trustee incurred pursuant to this paragraph.
It is not the intent of the foregoing provision that the Master Servicer or the
Special Servicer be permitted to invoke the procedure set forth herein with
respect to routine servicing matters arising hereunder, but rather only in the
case of unusual circumstances.

         SECTION 6.11. Certain Powers of the Controlling Class Representative.

         (a) Subject to Section 6.11(b), the Controlling Class Representative
will be entitled to advise the Master Servicer (in the event the Master Servicer
is authorized under this Agreement to take the subject action) or the Special
Servicer (in the event the Special Servicer is authorized under this Agreement
to take the subject action) with respect to any and all Specially Designated
Servicing Actions of such servicer with respect to the Mortgage Loans and any
REO Properties; and, further subject to Section 6.11(b), neither the Special
Servicer nor the Master Servicer, as applicable, will be permitted to take any
Specially Designated Servicing Action with respect to any Mortgage Loan or REO
Property unless and until it has notified the Controlling Class Representative
in writing and the Controlling Class Representative has not objected in writing
within ten (10) Business Days of having been notified thereof and having been
provided with all information that the Controlling Class Representative has
reasonably requested with respect thereto promptly following its receipt of the
subject notice (it being understood and agreed that if such written objection
has not been received by the Special Servicer or the Master Servicer, as
applicable, within such ten (10) Business Day period, then the Controlling Class
Representative will be deemed to have approved the taking of the subject
action); provided that, in the event that the Special Servicer or the Master
Servicer, as applicable, determines that failure to take such action would
violate the Servicing Standard, then the Special Servicer and the Master
Servicer, as applicable, may take any such action (other than an action
contemplated by clause (ix) of the definition of "Specially Designated Servicing
Action") without waiting for the Controlling Class Representative's

                                     -265-
<PAGE>

response; and provided, further, that the foregoing rights of the Controlling
Class Representative shall not relate to any Mortgage Loan that is part of, or
any REO Property that relates to, a Loan Combination, regarding which the rights
and powers set forth under Section 6.12 are instead applicable to the Mortgage
Loans comprising the GIC Office Loan Combination and the rights and powers set
forth under Section 6.13 are instead applicable to the Mortgage Loans comprising
the MGM Tower Loan Combination.

         In addition, subject to Section 6.11(b), the Controlling Class
Representative may direct the Special Servicer to take, or to refrain from
taking, any actions with respect to the servicing and/or administration of a
Specially Serviced Mortgage Loan or REO Property as the Controlling Class
Representative may deem advisable or as to which provision is otherwise made
herein; provided that the foregoing rights of the Controlling Class
Representative shall not relate to any Specially Serviced Mortgage Loan that is
part of, or any REO Property that relates to, a Loan Combination. Upon
reasonable request, the Special Servicer shall provide the Controlling Class
Representative with any information in such servicer's possession with respect
to such matters, including its reasons for determining to take a proposed
action; provided that such information shall also be provided, in a written
format, to the Trustee, who shall make it available for review pursuant to
Section 8.14(b).

         Each of the Master Servicer (with respect to Performing Serviced
Mortgage Loans) and the Special Servicer (with respect to Specially Serviced
Mortgage Loans), as applicable, shall notify the Controlling Class
Representative of any release or substitution of collateral for a Mortgage Loan
even if such release or substitution is required by the terms of such Mortgage
Loan.

         (b) Notwithstanding anything herein to the contrary, no advice,
direction or objection from or by the Controlling Class Representative, as
contemplated by Section 6.11(a), may (and the Special Servicer and the Master
Servicer shall each ignore and act without regard to any such advice, direction
or objection that such servicer has determined, in its reasonable, good faith
judgment, would) require or cause such servicer to violate any provision of this
Agreement (exclusive of Section 6.11(a)) (including such servicer's obligation
to act in accordance with the Servicing Standard), the related loan documents
(including any applicable co-lender and/or intercreditor agreements) or
applicable law (including the REMIC Provisions). Furthermore, the Special
Servicer shall not be obligated to seek approval from the Controlling Class
Representative for any actions to be taken by the Special Servicer with respect
to the workout or liquidation of any particular Specially Serviced Mortgage Loan
if:

                  (i) the Special Servicer has, as provided in Section 6.11(a),
         notified the Controlling Class Representative in writing of various
         actions that the Special Servicer proposes to take with respect to the
         workout or liquidation of such Mortgage Loan; and

                  (ii) for 60 days following the first such notice, the
         Controlling Class Representative has objected to all of those proposed
         actions and has failed to suggest any alternative actions that the
         Special Servicer considers to be consistent with the Servicing
         Standard.

         Also notwithstanding anything herein to the contrary, the provisions of
Section 6.11(a), and the rights and powers of the Controlling Class
Representative provided for in Section 6.11(a), shall not apply to any Loan
Combination or any related REO Property; provided that this paragraph is not
intended to limit any rights or powers that the Controlling Class Representative
may have under Section 6.12 or Section 6.l3.

                                     -266-
<PAGE>

         (c) The Controlling Class Representative will have no liability to the
Certificateholders for any action taken, or for refraining from the taking of
any action, in good faith pursuant to this Agreement, or for errors in judgment;
provided, however, that the Controlling Class Representative will not be
protected against any liability to any Controlling Class Certificateholder which
would otherwise be imposed by reason of willful misfeasance, bad faith or
negligence in the performance of duties or by reason of negligent disregard of
obligations or duties. Each Certificateholder acknowledges and agrees, by its
acceptance of its Certificates, that: (i) the Controlling Class Representative
may, and is permitted hereunder to, have special relationships and interests
that conflict with those of Holders of one or more Classes of Certificates; (ii)
the Controlling Class Representative may, and is permitted hereunder to, act
solely in the interests of the Holders of the Controlling Class; (iii) the
Controlling Class Representative does not have any duties or liability to the
Holders of any Class of Certificates other than the Controlling Class; (iv) the
Controlling Class Representative may, and is permitted hereunder to, take
actions that favor interests of the Holders of the Controlling Class over the
interests of the Holders of one or more other Classes of Certificates; (v) the
Controlling Class Representative shall not be deemed to have been negligent or
reckless, or to have acted in bad faith or engaged in willful misconduct, by
reason of its having acted solely in the interests of the Holders of the
Controlling Class; and (vi) the Controlling Class Representative shall have no
liability whatsoever for having acted solely in the interests of the Holders of
the Controlling Class, and no Certificateholder may take any action whatsoever
against the Controlling Class Representative, any Holder of the Controlling
Class or any director, officer, employee, agent or principal thereof for having
so acted.

         SECTION 6.12. Certain Matters Regarding the GIC Office Loan
                       Combination.

         (a) Subject to Section 6.12(b), and further subject to Section 3.01(b)
and Section 3.01(c) of the GIC Office Co-Lender Agreement, the GIC Office
Controlling Party will be entitled to advise the Special Servicer (in the event
the Special Servicer is authorized under this Agreement to take the subject
action) or the Master Servicer (in the event the Master Servicer is authorized
under this Agreement to take the subject action), as applicable, with respect to
any and all GIC Office Specially Designated Servicing Actions with respect to
the GIC Office Loan Group or any related REO Property; and, further subject to
Section 6.12(b), neither the Special Servicer nor the Master Servicer, as
applicable, will be permitted to take any of the GIC Office Specially Designated
Servicing Actions with respect to the GIC Office Loan Group or any related REO
Property unless and until it (i) has notified the GIC Office Non-Trust Mortgage
Loan Noteholders and the Controlling Class Representative in writing and (ii)
has obtained the prior written consent of the GIC Office Controlling Party
within ten (10) Business Days of the GIC Office Controlling Party having been
notified thereof and having been provided with all reasonably requested
information with respect thereto (it being understood and agreed that if no
affirmative objection to the subject action on the part of the GIC Office
Controlling Party has been received by the Special Servicer or the Master
Servicer, as applicable, within such ten (10) Business Day period, then the GIC
Office Controlling Party will be deemed to have approved of the subject action);
provided that, in the event that the Special Servicer or the Master Servicer, as
applicable, determines that immediate action is necessary to protect the
interests of the Certificateholders and the GIC Office Non-Trust Mortgage Loan
Noteholders (as a collective whole), the Special Servicer or the Master
Servicer, as the case may be, may take any such action without waiting for the
GIC Office Controlling Party's response; and provided, further, that, under
circumstances where the Controlling Class Representative is not the GIC Office
Controlling Party, nothing herein shall be intended to limit the right of the
Controlling Class Representative to consult with the Special Servicer or the
Master

                                     -267-
<PAGE>

Servicer, as applicable, regarding the GIC Office Trust Mortgage Loan, and
during the ten (10) Business Day period referred to above, the Special Servicer
or the Master Servicer, as applicable, shall consult with the Controlling Class
Representative regarding its views as to the proposed action (but may, in its
sole discretion, reject any advice, objection or direction from the Controlling
Class Representative) and, upon reasonable request, the Special Servicer or the
Master Servicer, as applicable, shall provide the Controlling Class
Representative with any information in such servicer's possession with respect
to such matters, including its reasons for determining to take a proposed
action.

         In addition, subject to Section 6.12(b), and Section 3.01(b) and
3.01(c) of the GIC Office Co-Lender Agreement, the GIC Office Controlling Party
may direct the Special Servicer or the Master Servicer, as appropriate based on
their respective duties hereunder, to take, or to refrain from taking, such
actions with respect to the GIC Office Loan Group or any related REO Property as
the GIC Office Controlling Party may deem consistent with the GIC Office
Co-Lender Agreement or as to which provision is otherwise made in the GIC Office
Co-Lender Agreement. Upon reasonable request, the Special Servicer or the Master
Servicer, as appropriate based on their respective duties hereunder, shall, with
respect to the GIC Office Loan Group, provide the GIC Office Controlling Party
with any information in such servicer's possession with respect to such matters,
including its reasons for determining to take a proposed action; provided that
such information shall also be provided, in a written format, to the Trustee,
who shall make it available for review pursuant to Section 8.14(b). Promptly
following the Special Servicer or the Master Servicer receiving any direction
from the GIC Office Controlling Party as contemplated by this paragraph, such
servicer shall notify the Trustee, the Controlling Class Representative (if it
is not the GIC Office Controlling Party) and each GIC Office Non-Trust Mortgage
Loan Noteholder (other than, if applicable, the GIC Office Controlling
Noteholder).

         The GIC Office Subordinate Non-Trust Mortgage Loan Noteholder will also
be entitled to advise the Master Servicer and the Special Servicer with respect
to any determination to be made by the lender with respect to the definition of
"Permitted Investments" contained in the loan agreement for the GIC Office Loan
Group, to the extent such determination is within the lender's discretion;
provided that no such determination and consequent selection of any investment
pursuant thereto shall result in an Adverse Rating Event with respect to any
Class of Certificates or any class of GIC Office Pari Passu Non-Trust Mortgage
Loan Securities. Subject to Section 6.12(b), neither the Master Servicer nor the
Special Servicer may take the foregoing action unless and until (i) it has
notified the Controlling Class Representative and each GIC Office Non-Trust
Mortgage Loan Noteholder in writing and (ii) the GIC Office Subordinate
Non-Trust Mortgage Loan Noteholder has not objected in writing within ten (10)
Business Days of having been notified thereof and having been provided with all
reasonably requested information with respect thereto (it being understood and
agreed that if such written objection has not been received by the Master
Servicer or the Special Servicer, as applicable, within such ten (10) Business
Day period, then the GIC Office Subordinate Non-Trust Mortgage Loan Noteholder's
approval will be deemed to have been given).

         Each of the Master Servicer (with respect to Performing Mortgage Loans)
and the Special Servicer (with respect to Specially Serviced Mortgage Loans), as
applicable, shall notify the GIC Office Non-Trust Mortgage Loan Noteholders, the
Controlling Class Representative and any other Person that may be the GIC Office
Controlling Party of any release or substitution of collateral for the GIC
Office Loan Group even if such release or substitution is required by the terms
of the GIC Office Loan Group.

         (b) Notwithstanding anything herein to the contrary, no advice,
direction or objection from or by the GIC Office Controlling Party, as
contemplated by Section 6.12(a), may (and the Special Servicer and the Master
Servicer shall each ignore and act without regard to any such advice, direction
or objection that the Special Servicer or the Master Servicer, as applicable,
has determined, in its reasonable, good faith judgment, would) require, cause or
permit such servicer to violate any provision of the GIC Office Co-Lender
Agreement or this Agreement (exclusive of Section 6.12(a)) (including such
servicer's obligation to act in accordance with the Servicing Standard), the
related loan documents or applicable law or result in an Adverse REMIC Event or
an Adverse Grantor Trust Event. Furthermore, neither the Special Servicer nor
the Master Servicer shall be obligated to seek approval from the GIC Office
Controlling Party for any actions to be taken by such servicer with respect to
the GIC Office Loan Group or any related REO Property if: (i) such servicer has,
as provided in Section 6.12(a), notified the GIC Office Controlling Party in
writing of various actions that such servicer proposes to take with respect to
the workout or liquidation of the GIC Office Loan Group; and (ii) for 60 days
following the first such notice, the GIC Office Controlling Party has objected
to all of those proposed actions and has failed to suggest any alternative
actions that such servicer considers to be consistent with the Servicing
Standard.

         Also notwithstanding the foregoing, each of the Master Servicer and the
Special Servicer, prior to such servicer's taking (or, in the case of the
Special Servicer, if and when appropriate under this Agreement, consenting to
the Master Servicer's taking) any of the GIC Office Specially Designated
Servicing Actions, and the Special Servicer, prior to such servicer's taking any
action at the direction of the GIC Office Controlling Party pursuant to the
second paragraph of Section 6.12(a), shall in each such case notify the
respective GIC Office Pari Passu Non-Trust Mortgage Loan Noteholders. Such GIC
Office Pari Passu Non-Trust Mortgage Loan Noteholders shall, upon receipt of
such notice, have ten (10) Business Days to advise and consult with the Master
Servicer or the Special Servicer, as applicable, with respect to such actions;
provided that the Master Servicer or the Special Servicer, as applicable, shall
not be obligated to take any advice from, or follow any direction given by, any
such GIC Office Pari Passu Non-Trust Mortgage Loan Noteholder; and provided,
further, that any such GIC Office Pari Passu Non-Trust Mortgage Loan
Noteholder's request to communicate with the Master Servicer or the Special
Servicer, as applicable, in accordance with this Section 6.12(b) must be made
within eight (8) Business Days of its receipt of notice in accordance with the
preceding sentence; and provided, further, that, in the event that the Master
Servicer or the Special Servicer, as applicable, determines that immediate
action is necessary to protect the interests of the Certificateholders and the
GIC Office Non-Trust Mortgage Loan Noteholders (as a collective whole), such
servicer may take (or, in the case of the Special Servicer, if and when
appropriate under this Agreement, may consent to the Master Servicer's taking)
the subject action without consulting with any GIC Office Pari Passu Non-Trust
Mortgage Loan Noteholder in accordance with this Section 6.12(b). The Master
Servicer or the Special Servicer, as applicable, within two (2) Business Days of
receiving any request from any GIC Office Pari Passu Non-Trust Mortgage Loan
Noteholder desiring to exercise its consultation rights under this Section
6.12(b), to make available to such requesting GIC Office Pari Passu Non-Trust
Mortgage Loan Noteholder, in person at the Primary Servicing Offices of such
servicer or by telephone conference, for a reasonable time period, one or more
of such servicer's officers responsible for the servicing and administration of
the GIC Office Loan Group or any related REO Property and, further, to
communicate with the GIC Office Controlling Party regarding any advice or other
views expressed by such requesting GIC Office Pari Passu Non-Trust Mortgage Loan
Noteholder regarding the subject servicing actions. Nothing contained in this
paragraph shall, or is intended to, limit or alter the GIC Office Controlling
Party's rights under Section 6.12(a).

                                     -269-
<PAGE>

         Any GIC Office Pari Passu Non-Trust Mortgage Loan Noteholder may
designate, in writing, a representative to exercise its rights under the prior
paragraph (copies of such writing to be delivered to the Trustee, to each of the
other GIC Office Pari Passu Non-Trust Mortgage Loan Noteholders and to the
Master Servicer and the Special Servicer). Such designation shall remain in
effect until it is revoked by the subject GIC Office Pari Passu Non-Trust
Mortgage Loan Noteholder by a writing delivered to the Trustee, the other GIC
Office Pari Passu Non-Trust Mortgage Loan Noteholders and the Special Servicer.

         (c) The GIC Office Controlling Party will not have any liability to the
Trust or the Certificateholders or any of the other GIC Office Non-Trust
Mortgage Loan Noteholders, in the case of a GIC Office Non-Trust Mortgage Loan
Noteholder or its designee acting in such capacity, or to any of the GIC Office
Non-Trust Mortgage Loan Noteholders, in the case of the Controlling Class
Representative acting in such capacity, for any action taken, or for refraining
from the taking of any action, in good faith pursuant to this Agreement or the
GIC Office Co-Lender Agreement, or for errors in judgment; provided, however,
that the GIC Office Controlling Party will not be protected against any
liability which would otherwise be imposed by reason of willful misfeasance, bad
faith or negligence in the performance of duties or by reason of negligent
disregard of obligations or duties.

         (d) The GIC Office Controlling Lender may, in accordance with Section
3.02(d) of the GIC Office Co-Lender Agreement, designate a representative to
exercise its rights and powers under Section 3.02 of the GIC Office Co-Lender
Agreement and this Section 6.12. In that regard, if and for so long as (but only
if and for so long as) a GIC Office Change of Control Event has occurred and is
continuing and the GIC Office Note A-1B Non-Trust Mortgage Loan Noteholder has
not been designated as the GIC Office Controlling Noteholder in accordance with
the next paragraph, the Controlling Class Representative (i) is hereby
designated as the representative of the Trust for purposes of exercising the
rights and powers of the "Lead Lender" under Sections 3.02(a) and 3.02(b) (and
to the extent they relate to the foregoing, Sections 3.02(c) and 3.02(e)) of the
GIC Office Co-Lender Agreement and (ii) shall be the GIC Office Controlling
Party. The Trustee shall take such actions as are necessary or appropriate to
make such designation effective in accordance with Section 3.02(d) of the GIC
Office Co-Lender Agreement. The Master Servicer shall provide the parties to
this Agreement with notice of the occurrence of a GIC Office Change of Control
Event, promptly upon becoming aware of thereof.

         The Trustee, on behalf of the Trust, as holder of the GIC Office Trust
Mortgage Loan or any successor REO Trust Mortgage Loan with respect thereto,
shall, if required pursuant to the following sentence, in accordance with the
definition of "Lead Lender" in the GIC Office Co-Lender Agreement, designate the
GIC Office Note A-1B Non-Trust Mortgage Loan Noteholder to be the GIC Office
Controlling Lender while a GIC Office Change of Control Event has occurred and
is continuing. In that regard, if and for so long as (but only if and for so
long as) a GIC Office Change of Control Event has occurred and is continuing,
the aggregate of the Class Principal Balances of the Class M, Class N, Class P,
Class Q, Class S and Class T Certificates has been reduced to zero, the Class
Principal Balance of the Class L Certificates is less than 25% of the original
Class Principal Balance of the Class L Certificates and the GIC Office Note A-1B
Non-Trust Mortgage Loan or any successor REO Mortgage Loan with respect thereto
is part of a commercial mortgage securitization trust established by the
Depositor, the GIC Office Note A-1B Non-Trust Mortgage Loan Noteholder is hereby
designated as, and shall be, the GIC Office Controlling Lender. The Trustee
shall take such actions as are necessary or

                                     -270-
<PAGE>

appropriate to make such designation effective in accordance with Section
3.02(d) of, and the definition of "Lead Lender" in, the GIC Office Co-Lender
Agreement.

         (e) Each GIC Office Non-Trust Mortgage Loan Noteholder shall be
entitled to receive, upon request, a copy of any notice or report required to be
delivered (upon request or otherwise) to the Trustee with respect to the GIC
Office Loan Group or any related REO Property by any other party hereto. Any
such other party shall be permitted to require payment of a sum sufficient to
cover the reasonable costs and expenses of providing such copies in accordance
with this Section 6.12(e).

         (f) Notwithstanding anything herein to the contrary, any appointment of
a successor Special Servicer hereunder, insofar as it affects the GIC Office
Loan Group or any related REO Property, will be subject to the consultation
rights of the GIC Office Subordinate Non-Trust Mortgage Loan Noteholder under
Section 3.02 of the GIC Office Co-Lender Agreement. The parties hereto further
recognize such other rights of the GIC Office Non-Trust Mortgage Loan
Noteholders as are set forth in Section 3.02 of the GIC Office Co-Lender
Agreement and are not otherwise addressed herein.

         SECTION 6.13. Certain Matters Regarding the MGM Tower Loan Combination.

         (a) Subject to Section 6.13(b), and further subject to Section 3.01(b)
and Section 3.01(c) of the MGM Tower Co-Lender Agreement, the MGM Tower
Controlling Party will be entitled to advise the Special Servicer (in the event
the Special Servicer is authorized under this Agreement to take the subject
action) or the Master Servicer (in the event the Master Servicer is authorized
under this Agreement to take the subject action), as applicable, with respect to
any and all MGM Tower Specially Designated Servicing Actions with respect to the
MGM Tower Loan Pair or any related REO Property; and, further subject to Section
6.13(b), neither the Special Servicer nor the Master Servicer will be permitted
to take any of the MGM Tower Specially Designated Servicing Actions with respect
to the MGM Tower Loan Pair or any related REO Property unless and until (i) it
has notified the MGM Tower Non-Trust Mortgage Loan Noteholder and the
Controlling Class Representative in writing and (ii) the MGM Tower Controlling
Party has not objected in writing within ten (10) Business Days of having been
notified thereof and having been provided with all reasonably requested
information with respect thereto (it being understood and agreed that if such
written objection has not been received by the Special Servicer or the Master
Servicer, as applicable, within such ten (10) Business Day period, then the MGM
Tower Controlling Party will be deemed to have approved of the subject action);
provided that, in the event that the Special Servicer or the Master Servicer, as
applicable, determines that immediate action is necessary to protect the
interests of the Certificateholders and the MGM Tower Non-Trust Mortgage Loan
Noteholder (as a collective whole), the Special Servicer or the Master Servicer,
as the case may be, may take any such action without waiting for the MGM Tower
Controlling Party's response; and provided, further, that, under circumstances
where the Controlling Class Representative is not the MGM Tower Controlling
Party, nothing herein shall be intended to limit the right of the Controlling
Class Representative to consult with the Special Servicer or the Master
Servicer, as applicable, regarding the MGM Tower Trust Mortgage Loan, and during
the ten (10) Business Day period referred to above, the Special Servicer or the
Master Servicer, as applicable, shall consult with the Controlling Class
Representative regarding its views as to the proposed action (but may, in its
sole discretion, reject any advice, objection or direction from the Controlling
Class Representative) and, upon reasonable request, the Special Servicer or the
Master Servicer, as applicable, shall provide the Controlling Class
Representative with any information in such servicer's possession with respect
to such matters, including its reasons for determining to take a proposed
action.

                                     -271-
<PAGE>

         In addition, subject to Section 6.13(b), and further subject to Section
3.01(b) and Section 3.01(c) of the MGM Tower Co-Lender Agreement, the MGM Tower
Controlling Party may direct the Special Servicer or the Master Servicer, as
appropriate based on their respective duties hereunder, to take, or to refrain
from taking, such actions with respect to the MGM Tower Loan Pair or any related
REO Property as the MGM Tower Controlling Party may deem consistent with the MGM
Tower Co-Lender Agreement or as to which provision is otherwise made in the MGM
Tower Co-Lender Agreement. Upon reasonable request, the Special Servicer or the
Master Servicer, as appropriate based on their respective duties hereunder,
shall, with respect to the MGM Tower Loan Pair, provide the MGM Tower
Controlling Party with any information in such servicer's possession with
respect to such matters, including its reasons for determining to take a
proposed action; provided that such information shall also be provided, in a
written format, to the Trustee who shall make it available for review pursuant
to Section 8.14(b). Promptly following the Special Servicer or the Master
Servicer receiving any direction from the MGM Tower Controlling Party as
contemplated by this paragraph, such servicer shall notify the Trustee, the
Controlling Class Representative (if it is not the MGM Tower Controlling Party)
and the MGM Tower Non-Trust Mortgage Loan Noteholder (if neither it nor its
designee is the MGM Tower Controlling Party).

         Each of the Master Servicer (with respect to Performing Mortgage Loans)
and the Special Servicer (with respect to Specially Serviced Mortgage Loans), as
applicable, shall notify the MGM Tower Non-Trust Mortgage Loan Noteholder, the
Controlling Class Representative and any other Person that may be the MGM Tower
Controlling Party of any release or substitution of collateral for the MGM Tower
Loan Pair even if such release or substitution is required by the terms of the
MGM Tower Loan Pair.

         The MGM Tower Non-Trust Mortgage Loan Noteholder will also be entitled
to advise the Master Servicer and the Special Servicer with respect to any
determination to be made by the lender with respect to the definition of
"Permitted Investments" contained in the loan agreement for the MGM Tower Loan
Pair, to the extent such determination is within the lender's discretion;
provided that no such determination and consequent selection of any investment
pursuant thereto shall result in an Adverse Rating Event with respect to any
Class of Certificates. Subject to Section 6.13(b), neither the Master Servicer
nor the Special Servicer may take the foregoing action unless and until (i) it
has notified the MGM Tower Non-Trust Mortgage Loan Noteholder and the
Controlling Class Representative in writing and (ii) the MGM Tower Non-Trust
Mortgage Loan Noteholder has not objected in writing within ten (10) Business
Days of having been notified thereof and having been provided with all
reasonably requested information with respect thereto (it being understood and
agreed that if such written objection has not been received by the Master
Servicer or the Special Servicer, as applicable, within such ten (10) Business
Day period, then the MGM Tower Non-Trust Mortgage Loan Noteholder's approval
will be deemed to have been given).

         (b) Notwithstanding anything herein to the contrary, no advice,
direction or objection from or by the MGM Tower Controlling Party, as
contemplated by Section 6.13(a), may (and the Special Servicer and the Master
Servicer shall each ignore and act without regard to any such advice, direction
or objection that such servicer has determined, in its reasonable, good faith
judgment, would) require, cause or permit such servicer to violate any provision
of the MGM Tower Co-Lender Agreement or this Agreement (exclusive of Section
6.13(a)) (including such servicer's obligation to act in accordance with the
Servicing Standard), the related loan documents or applicable law or result in
an Adverse REMIC Event or an Adverse Grantor Trust Event. Furthermore, neither
the Master Servicer

                                     -272-
<PAGE>

nor the Special Servicer shall be obligated to seek approval from the MGM Tower
Controlling Party for any actions to be taken by such servicer with respect to
the MGM Tower Loan Pair or any related REO Property if: (i) such servicer has,
as provided in Section 6.13(a), notified the MGM Tower Controlling Party in
writing of various actions that such servicer proposes to take with respect to
the workout or liquidation of the MGM Tower Loan Pair; and (ii) for 60 days
following the first such notice, the MGM Tower Controlling Party has objected to
all of those proposed actions and has failed to suggest any alternative actions
that such servicer considers to be consistent with the Servicing Standard.

         (c) The MGM Tower Controlling Party will not have any liability to the
Trust or the Certificateholders, in the case of the MGM Tower Non-Trust Mortgage
Loan Noteholder or its designee acting in such capacity, or to the MGM Tower
Non-Trust Mortgage Loan Noteholder, in the case of the Controlling Class
Representative acting in such capacity, for any action taken, or for refraining
from the taking of any action, in good faith pursuant to this Agreement or the
MGM Tower Co-Lender Agreement, or for errors in judgment; provided, however,
that the MGM Tower Controlling Party will not be protected against any liability
which would otherwise be imposed by reason of willful misfeasance, bad faith or
negligence in the performance of duties or by reason of negligent disregard of
obligations or duties.

         (d) The MGM Tower Controlling Lender may, in accordance with Section
3.02(d) of the MGM Tower Co-Lender Agreement, designate a representative to
exercise its rights and powers under Section 3.02 of the MGM Tower Co-Lender
Agreement and this Section 6.13. In that regard, if and for so long as (but only
if and for so long as) an MGM Tower Change of Control Event has occurred and is
continuing, the Controlling Class Representative (i) is hereby designated as the
representative of the Trust for purposes of exercising the rights and powers of
the "Lead Lender" under Sections 3.02(a) and 3.02(b) (and to the extent they
relate to the foregoing, Section 3.02(c)) of the MGM Tower Co-Lender Agreement
and (ii) shall be the MGM Tower Controlling Party. The Trustee shall take such
actions as are necessary or appropriate to make such designation effective in
accordance with Section 3.02(d) of the MGM Tower Co-Lender Agreement. The Master
Servicer shall provide the parties to this Agreement with notice of the
occurrence of a MGM Tower Change of Control Event, promptly upon becoming aware
of thereof.

         (e) The MGM Tower Non-Trust Mortgage Loan Noteholder shall be entitled
to receive, upon request, a copy of any notice or report required to be
delivered (upon request or otherwise) to the Trustee with respect to the MGM
Tower Loan Pair or any related REO Property by any other party hereto. Any such
other party shall be permitted to require payment of a sum sufficient to cover
the reasonable costs and expenses of providing such copies in accordance with
this Section 6.13(e).

         (f) Notwithstanding anything herein to the contrary, any appointment of
a successor Special Servicer hereunder, insofar as it affects the MGM Tower Loan
Pair or any related REO Property, will be subject to the consultation rights of
the MGM Tower Non-Trust Mortgage Loan Noteholder under Section 3.02 of the MGM
Tower Co-Lender Agreement. The parties hereto further recognize such other
rights of the MGM Tower Non-Trust Mortgage Loan Noteholder and, if different,
the MGM Tower Controlling Party as are set forth in Section 3.02 of the MGM
Tower Co-Lender Agreement and are not otherwise addressed herein.

         Servicer, as the case may be, obtains actual knowledge that Moody's has
         (1) qualified, downgraded or withdrawn its rating or ratings of one or
         more Classes of the Certificates or one or more classes of any GIC
         Office Pari Passu Non-Trust Mortgage Loan Securities or (2) placed one
         or more

                                     -275-

         Classes of the Certificates or one or more classes of any GIC Office
         Pari Passu Non-Trust Mortgage Loan Securities on "watch status" (and
         such "watch status" placement shall not have been withdrawn by Moody's
         within 60 days of the date when the Servicing Officer of the Master
         Servicer or the Special Servicer, as the case may be, obtained such
         actual knowledge) and, in the case of either clause (1) or (2), cited
         servicing concerns with the Master Servicer or the Special Servicer, as
         the case may be, as the sole or material factor in such rating action;
         or

                  (xi) the Master Servicer or the Special Servicer is removed
         from S&P's approved master servicer list or special servicer list, as
         the case may be, and the ratings of one or more Classes of the
         Certificates or one or more classes of any GIC Office Pari Passu
         Non-Trust Mortgage Loan Securities by S&P are qualified, downgraded or
         withdrawn in connection with the removal.

         When a single entity acts as the Master Servicer and the Special
Servicer, an Event of Default in one capacity shall constitute an Event of
Default in the other capacity.

         (b) If any Event of Default described in any of clauses (i) - (ix) and
(xi) of subsection (a) above shall occur with respect to the Master Servicer or
the Special Servicer (in either case, for purposes of this Section 7.01(b), the
"Defaulting Party") and shall be continuing, then, and in each and every such
case, so long as such Event of Default shall not have been remedied, the Trustee
may, and at the written direction of the Holders of Certificates entitled to at
least 25% of the Voting Rights, the Trustee shall, by notice in writing to the
Defaulting Party (with a copy of such notice to each other party hereto and the
Rating Agencies) terminate all of the rights and obligations (but not the
liabilities for actions and omissions occurring prior thereto) of the Defaulting
Party under this Agreement and in and to the Trust Fund and the Non-Trust
Mortgage Loans, other than its rights, if any, as a Certificateholder hereunder
or as the holder of any Non-Trust Mortgage Loan or any interest therein;
provided that the Master Servicer may not be terminated solely for an Event of
Default that affects only a Non-Trust Mortgage Loan Noteholder or any class of
GIC Office Pari Passu Non-Trust Mortgage Loan Securities (except that a
Sub-Servicer may be appointed in accordance with Section 7.01(d)); and provided,
further, that, except as provided in Section 7.01(d), the Special Servicer may
not be terminated solely for an Event of Default that affects only a Non-Trust
Mortgage Loan Noteholder or any class of GIC Office Pari Passu Non-Trust
Mortgage Loan Securities. If any Event of Default described in clause (x) of
subsection (a) above shall occur with respect to the Master Servicer or the
Special Servicer (in either case, under such circumstances, for purposes of this
Section 7.01(b), the "Defaulting Party"), then the Trustee shall, by notice in
writing (to be sent immediately by facsimile transmission) to the Defaulting
Party (with a copy of such notice to each other party hereto and the Rating
Agencies), terminate all of the rights and obligations (but not the liabilities
for actions and omissions occurring prior thereto) of the Defaulting Party under
this Agreement and in and to the Trust Fund and the Non-Trust Mortgage Loans,
other than its rights, if any, as a Certificateholder hereunder or as the holder
of any Non-Trust Mortgage Loan or any interest therein, within 30 days following
the occurrence of such Event of Default; provided that the Master Servicer may
not be terminated solely for an Event of Default that affects only a Non-Trust
Mortgage Loan Noteholder or any class of GIC Office Pari Passu Non-Trust
Mortgage Loan Securities (except that a Sub-Servicer may be appointed in
accordance with Section 7.01(d)); and provided, further, that, except as
provided in Section 7.01(d), the Special Servicer may not be terminated solely
for an Event of Default that affects only a Non-Trust Mortgage Loan Noteholder
or any class of GIC Office Pari Passu Non-Trust Mortgage Loan Securities. From
and after the receipt by the Defaulting Party of such written notice of
termination, subject to Section 7.01(c), all authority and

                                     -276-
<PAGE>

power of the Defaulting Party under this Agreement, whether with respect to the
Certificates (other than as a holder of any Certificate), the Trust Fund, the
Non-Trust Mortgage Loans (other than as a holder thereof or any interest
therein) or otherwise, shall pass to and be vested in the Trustee pursuant to
and under this section, and, without limitation, the Trustee is hereby
authorized and empowered to execute and deliver, on behalf of and at the expense
of the Defaulting Party, as attorney-in-fact or otherwise, any and all documents
and other instruments, and to do or accomplish all other acts or things
necessary or appropriate to effect the purposes of such notice of termination,
whether to complete the transfer and endorsement or assignment of the Mortgage
Loans and related documents, or otherwise. The Master Servicer and the Special
Servicer each agree that, if it is terminated pursuant to this Section 7.01(b),
it shall promptly (and in any event no later than ten (10) Business Days
subsequent to its receipt of the notice of termination) provide the Trustee with
all documents and records, including those in electronic form, requested thereby
to enable the Trustee to assume the Master Servicer's or Special Servicer's, as
the case may be, functions hereunder, and shall cooperate with the Trustee in
effecting the termination of the Master Servicer's or Special Servicer's, as the
case may be, responsibilities and rights hereunder, including (i) if the Master
Servicer is the Defaulting Party, the immediate transfer to the Trustee or a
successor Master Servicer for administration by it of all cash amounts that
shall at the time be or should have been credited by the Master Servicer to a
Custodial Account, the Collection Account, the Defeasance Deposit Account, a
Servicing Account or a Reserve Account or that are thereafter received by or on
behalf of it with respect to any Mortgage Loan or (ii) if the Special Servicer
is the Defaulting Party, the transfer within two (2) Business Days to the
Trustee or a successor Special Servicer for administration by it of all cash
amounts that shall at the time be or should have been credited by the Special
Servicer to an REO Account, a Custodial Account, a Servicing Account or a
Reserve Account or should have been delivered to the Master Servicer or that are
thereafter received by or on behalf of it with respect to any Mortgage Loan or
REO Property; provided, however, that the Master Servicer and the Special
Servicer each shall, if terminated pursuant to this Section 7.01(b), continue to
be entitled to receive all amounts accrued or owing to it under this Agreement
on or prior to the date of such termination, whether in respect of Advances or
otherwise, and it shall continue to be entitled to the benefits of Section 6.03
notwithstanding any such termination. Any cost or expenses in connection with
any actions to be taken by any party hereto pursuant to this paragraph shall be
borne by the Defaulting Party and if not paid by the Defaulting Party within 90
days after the presentation of reasonable documentation of such costs and
expenses, such expense shall be reimbursed by the Trust Fund; provided, however,
that the Defaulting Party shall not thereby be relieved of its liability for
such expenses. For purposes of this Section 7.01 and also for purposes of
Section 7.03(b), the Trustee shall not be deemed to have knowledge of an event
which constitutes, or which with the passage of time or notice, or both, would
constitute an Event of Default unless a Responsible Officer of the Trustee
assigned to and working in the Trustee's Corporate Trust Office has actual
knowledge thereof or unless notice of any event which is in fact such an Event
of Default is received by the Trustee and such notice references the
Certificates, the Trust Fund or this Agreement.

         (c) In the case of an Event of Default under Section 7.01(a)(x) or (xi)
of which the Trustee has notice, the Trustee shall provide written notice
thereof to the Master Servicer promptly upon receipt of such notice.
Notwithstanding Section 7.01(b), if the Master Servicer receives a notice of
termination under Section 7.01(b) solely due to an Event of Default under
Section 7.01(a)(x) or (xi), and if the terminated Master Servicer provides the
Trustee with the appropriate "request for proposal" materials within five (5)
Business Days following such termination, then the Master Servicer shall
continue to serve in such capacity hereunder until a successor thereto is
selected in accordance with this Section 7.01(c) or the expiration of 45 days
from the Master Servicer's receipt of the notice of

                                     -277-
<PAGE>

termination, whichever occurs first. Upon receipt of such "request for proposal"
materials from the terminated Master Servicer, the Trustee shall promptly
thereafter (using such "request for proposal" materials) solicit good faith bids
for the rights to master service the Mortgage Loans under this Agreement from at
least three (3) Persons qualified to act as a successor Master Servicer
hereunder in accordance with Section 6.02 and Section 7.02 (any such Person so
qualified, a "Qualified Bidder") or, if three (3) Qualified Bidders cannot be
located, then from as many Persons as the Trustee can determine are Qualified
Bidders; provided that at the Trustee's request, the terminated Master Servicer
shall supply the Trustee with the names of Persons from whom to solicit such
bids; and provided, further, that the Trustee shall not be responsible if less
than three (3) or no Qualified Bidders submit bids for the right to master
service the Mortgage Loans under this Agreement. The bid proposal shall require
any Successful Bidder (as defined below), as a condition of such bid, to enter
into this Agreement as successor Master Servicer, and to agree to be bound by
the terms hereof, within 45 days after the receipt of notice of termination by
the terminated Master Servicer. The Trustee shall solicit bids: (i) on the basis
of such successor Master Servicer retaining all Sub-Servicers to continue the
primary servicing of the Mortgage Loans pursuant to the terms of the respective
Sub-Servicing Agreements and to enter into a Sub-Servicing Agreement with the
terminated Master Servicer to sub-service each of the Mortgage Loans not subject
to a Sub-Servicing Agreement at a sub-servicing fee rate per annum equal to the
related Master Servicing Fee Rate minus, in the case of each Trust Mortgage Loan
serviced, one and one-half (1.5) basis points (each, a "Servicing-Retained
Bid"); and (ii) on the basis of terminating each Sub-Servicing Agreement and
Sub-Servicer that it is permitted to terminate in accordance with Section 3.22
(each, a "Servicing-Released Bid"). The Trustee shall select the Qualified
Bidder with the highest cash Servicing-Retained Bid (or, if none, the highest
cash Servicing Released Bid) (the "Successful Bidder") to act as successor
Master Servicer hereunder. The Trustee shall direct the Successful Bidder to
enter into this Agreement as successor Master Servicer pursuant to the terms
hereof (and, if the successful bid was a Servicing-Retained Bid, to enter into a
Sub-Servicing Agreement with the terminated Master Servicer as contemplated
above) no later than 45 days after the receipt of notice of termination by the
terminated Master Servicer.

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

         The terminated Master Servicer shall be responsible for all
out-of-pocket expenses incurred in connection with the attempt to sell its
rights to master service the Mortgage Loans, which expenses are not reimbursed
to the party that incurred such expenses pursuant to the preceding paragraph.

         If the Successful Bidder has not entered into this Agreement as
successor Master Servicer within 45 days after the terminated Master Servicer
received written notice of termination or no Successful Bidder was identified
within such 45-day period, then the terminated Master Servicer shall reimburse
the Trustee for all reasonable "out-of-pocket" expenses incurred by the Trustee
in connection with such bid process and the Trustee shall have no further
obligations under this Section 7.01(c). The Trustee thereafter may act or may
select a successor to act as Master Servicer hereunder in accordance with
Section 7.02.

                                     -278-
<PAGE>

         (d) Notwithstanding Section 7.01(b) and Section 7.04, if any Event of
Default on the part of the Master Servicer occurs that: (1) affects a Non-Trust
Mortgage Loan Noteholder or any Class of GIC Office Pari Passu Non-Trust
Mortgage Loan Securities, and the Master Servicer is not otherwise terminated in
accordance with Section 7.01(b), then the Master Servicer may not be terminated
by or at the direction of the related Non-Trust Mortgage Loan Noteholder, or (2)
affects solely a Non-Trust Noteholder or any Class of GIC Office Pari Passu
Non-Trust Mortgage Loan Securities, then the Master Servicer may not be
terminated by the Trustee; provided, however, in the case of (1) or (2), at the
request of such affected Non-Trust Mortgage Loan Noteholder, the Trustee shall
require the Master Servicer to appoint, within 30 days of the Trustee's request,
a Sub-Servicer (or, if the related Loan Combination is currently being
sub-serviced, to replace, within 30 days of the Trustee's request, the
then-current Sub-Servicer with a new Sub-Servicer) with respect to the related
Loan Combination. In connection with the Master Servicer's appointment of a
Sub-Servicer at the request of the Trustee in accordance with this Section
7.01(d), the Master Servicer shall obtain written confirmation from each Rating
Agency that such appointment will not result in an Adverse Rating Event with
respect to any Class of Certificates or, if the GIC Office Loan Group is
involved, any class of GIC Office Pari Passu Non-Trust Mortgage Loan Securities
rated by such Rating Agency. The related Sub-Servicing Agreement shall provide
that any Sub-Servicer appointed by the Master Servicer at the request of the
Trustee in accordance with this Section 7.01(d) shall be responsible for all
duties, and shall be entitled to all compensation, of the Master Servicer under
this Agreement with respect to the subject Loan Combination, except that the
Master Servicer shall be entitled to retain a portion of the Master Servicing
Fee for the Trust Mortgage Loan or REO Trust Mortgage Loan included in the
subject Loan Combination calculated at 0.015% per annum. Such Sub-Servicing
Agreement shall also provide that such Sub-Servicer shall agree to become the
master servicer under a separate servicing agreement (as contemplated by the
related Co-Lender Agreement) in the event that the subject Loan Combination is
no longer to be serviced and administered hereunder, which separate servicing
agreement shall contain servicing and administration, limitation of liability,
indemnification and servicing compensation provisions substantially similar to
the corresponding provisions of this Agreement, except for the fact that the
subject Loan Combination and the related Mortgaged Property shall be the sole
assets serviced and administered thereunder and the sole source of funds
thereunder. If any Sub-Servicer appointed by the Master Servicer at the request
of the Trustee in accordance with this Section 7.01(d) shall at any time resign
or be terminated, the Master Servicer shall be required to promptly appoint a
substitute Sub-Servicer, which appointment shall not result in an Adverse Rating
Event with respect to any Class of Certificates or, if the GIC Office Loan Group
is involved, any class of GIC Office Pari Passu Non-Trust Mortgage Loan
Securities rated by either Rating Agency (as evidenced in writing by each Rating
Agency). In the event that a successor Master Servicer is acting hereunder and
that successor Master Servicer desires to terminate the Sub-Servicer appointed
under this Section 7.01(d), the terminated Master Servicer that was responsible
for the Event of Default that led to the appointment of such Sub-Servicer shall
be responsible for all costs incurred in connection with such termination,
including the payment of any termination fee.

         Further notwithstanding Section 7.01(b) and Section 7.04, if any Event
of Default on the part of the Special Servicer occurs that affects a Non-Trust
Mortgage Loan Noteholder, and the Special Servicer is not otherwise terminated
in accordance with Section 7.01(b), then such Non-Trust Mortgage Loan Noteholder
may require the Trustee to terminate the duties and obligations of the Special
Servicer with respect to the related Loan Combination only, but as to no other
Mortgage Loan; and, in such event, subject to the applicable consultation rights
of any particular related Non-Trust Mortgage Loan Noteholder under Section 3.02
of the related Co-Lender Agreement, the Controlling Class

                                     -279-
<PAGE>

Representative shall appoint in accordance with Section 6.09 (or, in the event
of the failure of the Controlling Class Representative to so appoint, the
Trustee shall appoint in accordance with Section 7.02), within 30 days of such
Non-Trust Mortgage Loan Noteholder's request, a replacement special servicer
with respect to any Loan Combination. In connection with the appointment of a
replacement special servicer with respect to a Loan Combination at the request
of a related Non-Trust Mortgage Loan Noteholder in accordance with this Section
7.01(d), the Trustee shall obtain written confirmation from each Rating Agency
that such appointment will not result in an Adverse Rating Event with respect to
any Class of Certificates or, if the GIC Office Loan Group is involved, any
class of GIC Office Pari Passu Non-Trust Mortgage Loan Securities rated by such
Rating Agency (such Rating Agency confirmation to be an expense of the
requesting Non-Trust Mortgage Loan Noteholder). Any replacement special servicer
appointed at the request of a Non-Trust Mortgage Loan Noteholder in accordance
with this Section 7.01(d) shall be responsible for all duties, and shall be
entitled to all compensation, of the Special Servicer under this Agreement with
respect to the subject Loan Combination. Any replacement special servicer
appointed at the request of a Non-Trust Mortgage Loan Noteholder in accordance
with this Section 7.01(d) hereby agrees to become the special servicer under a
separate servicing agreement (as contemplated by the related Co-Lender
Agreement) in the event that the subject Loan Combination is no longer to be
serviced and administered hereunder, which separate servicing agreement shall
contain servicing and administration, limitation of liability, indemnification
and servicing compensation provisions substantially similar to the corresponding
provisions of this Agreement, except for the fact that the subject Loan
Combination and the related Mortgaged Property shall be the sole assets serviced
and administered thereunder and the sole source of funds thereunder. If any
replacement special servicer appointed at the request of a Non-Trust Mortgage
Loan Noteholder in accordance with this Section 7.01(d) shall at any time resign
or be terminated, then (subject to the applicable consultation rights of any
particular related Non-Trust Mortgage Loan Noteholder under Section 3.02 of the
related Co-Lender Agreement) the Controlling Class Representative in accordance
with Section 6.09 (or the Trustee in accordance with Section 7.02, if the
Controlling Class Representative fails to do so) shall be required to promptly
appoint a substitute replacement special servicer, which appointment shall not
result in an Adverse Rating Event (as evidenced in writing by each Rating
Agency) with respect to any Class of Certificates or, if the GIC Office Loan
Group is involved, any class of GIC Office Pari Passu Non-Trust Mortgage Loan
Securities rated by such Rating Agency.

         If a replacement special servicer is appointed with respect to a Loan
Combination at the request of a related Non-Trust Mortgage Loan Noteholder in
accordance with this Section 7.01(d) (any such replacement special servicer, a
"Loan Combination-Specific Special Servicer"), such that there are multiple
parties acting as Special Servicer hereunder, then, unless the context clearly
requires otherwise: (i) when used in the context of imposing duties and
obligations on the Special Servicer hereunder or the performance of such duties
and obligations, the term "Special Servicer" shall mean the related Loan
Combination-Specific Special Servicer, insofar as such duties and obligations
relate to a Loan Combination as to which a Loan Combination-Specific Special
Servicer has been appointed, and shall mean the General Special Servicer (as
defined below), in all other cases (provided that, in Section 3.13, Section 3.14
and Section 3.15, the term "Special Servicer" shall mean each of the Loan
Pair-Specific Special Servicer(s) and the General Special Servicer); (ii) when
used in the context of identifying the recipient of any information, funds,
documents, instruments and/or other items, the term "Special Servicer" shall
mean the related Loan Combination-Specific Special Servicer, insofar as such
information, funds, documents, instruments and/or other items relate to a Loan
Combination as to which a Loan Combination-Specific Special Servicer has been
appointed, and shall mean the General Special

                                     -280-
<PAGE>

Servicer, in all other cases; (iii) when used in the context of granting the
Special Servicer the right to purchase Specially Serviced Trust Mortgage Loans
pursuant to Section 3.18, the term "Special Servicer" shall mean the related
Loan Combination-Specific Special Servicer, if such Specially Serviced Trust
Mortgage Loan is part of a Loan Combination as to which a Loan
Combination-Specific Special Servicer has been appointed, and shall mean the
General Special Servicer, in all other cases; (iv) when used in the context of
granting the Special Servicer the right to purchase all of the Trust Mortgage
Loans and any REO Properties remaining in the Trust Fund pursuant to Section
9.01, the term "Special Servicer" shall mean the General Special Servicer only;
(v) when used in the context of granting the Special Servicer any protections,
limitations on liability, immunities and/or indemnities hereunder, the term
"Special Servicer" shall mean each of the Loan Combination-Specific Special
Servicer(s) and the General Special Servicer; and (vi) when used in the context
of requiring indemnification from, imposing liability on, or exercising any
remedies against, the Special Servicer for any breach of a representation,
warranty or covenant hereunder or for any negligence, bad faith or willful
misconduct in the performance of duties and obligations hereunder or any
negligent disregard of such duties and obligations or otherwise holding the
Special Servicer responsible for any of the foregoing, the term "Special
Servicer" shall mean the related Loan Combination-Specific Special Servicer or
the General Special Servicer, as applicable. References in this Section 7.01(d)
to "General Special Servicer" means the Person performing the duties and
obligations of special servicer with respect to the Mortgage Pool (exclusive of
each Loan Combination as to which a Loan Combination-Specific Special Servicer
has been appointed).

         In no event shall any waiver of an Event of Default pursuant to Section
7.04 affect the rights of any Non-Trust Mortgage Loan Noteholder under this
Section 7.01(d).

         SECTION 7.02. Trustee to Act; Appointment of Successor.

         On and after the time the Master Servicer or the Special Servicer
resigns pursuant to Section 6.04 or receives a notice of termination pursuant to
Section 7.01, the Trustee shall, unless and until a successor is appointed
pursuant to Section 6.04, Section 6.09 or Section 7.01(c), be the successor in
all respects to the Master Servicer or the Special Servicer, as the case may be,
in its capacity as such under this Agreement and the transactions set forth or
provided for herein and shall have all (and the former Master Servicer or the
Special Servicer, as the case may be, shall cease to have any) of the
responsibilities, duties and liabilities of the Master Servicer or the Special
Servicer, as the case may be, arising thereafter, including, if the Master
Servicer is the resigning or terminated party, the Master Servicer's obligation
to make P&I Advances, including in connection with any termination of the Master
Servicer for an Event of Default described in clause 7.01(a)(iii), the unmade
P&I Advances that gave rise to such Event of Default; provided that any failure
to perform such duties or responsibilities caused by the Master Servicer's or
the Special Servicer's, as the case may be, failure to provide information or
monies required by Section 7.01 shall not be considered a default by the Trustee
hereunder. The Trustee shall not be liable for any of the representations and
warranties of the resigning or terminated party or for any losses incurred by
the resigning or terminated party pursuant to Section 3.06 hereunder nor shall
the Trustee be required to purchase any Mortgage Loan hereunder. As compensation
therefor, the Trustee shall be entitled to all fees and other compensation which
the resigning or terminated party would have been entitled to if the resigning
or terminated party had continued to act hereunder. Notwithstanding the above,
the Trustee may, if it shall be unwilling to so act as either Master Servicer or
Special Servicer, as the case may be, or shall, if it is unable to so act as
either Master Servicer or Special Servicer, as the case may be, or if the
Trustee is not approved as a

                                     -281-
<PAGE>

master servicer or a special servicer, as the case may be, by any of the Rating
Agencies, or if the Holders of Certificates entitled to a majority of the Voting
Rights so request in writing to the Trustee, promptly appoint (subject, in the
case of a resigning or terminated Special Servicer, to the applicable
non-binding consultation rights of particular Non-Trust Mortgage Loan
Noteholders under Section 3.02 of each Co-Lender Agreement), or petition a court
of competent jurisdiction to appoint, any established mortgage loan servicing
institution as the successor to the resigning or terminated Master Servicer or
the Special Servicer, as the case may be, hereunder in the assumption of all or
any part of the responsibilities, duties or liabilities of the resigning or
terminated Master Servicer or the Special Servicer, as the case may be,
hereunder; provided, however, that no such appointee shall succeed to the rights
and obligations of the Master Servicer or Special Servicer hereunder unless (i)
as confirmed in writing by each Rating Agency, such succession will not result
in an Adverse Rating Event with respect to any Class of Certificates or any
class of GIC Office Pari Passu Non-Trust Mortgage Loan Securities rated by such
Rating Agency, and (ii) such appointee makes the applicable representations and
warranties set forth in Section 3.23; and provided, further, that in the case of
a resigning or terminated Special Servicer, such appointment shall be subject to
the rights of the Holders of Certificates evidencing a majority of the Voting
Rights allocated to the Controlling Class to designate a successor pursuant to
Section 6.09. No appointment of a successor to the Master Servicer or the
Special Servicer hereunder shall be effective until the assumption by the
successor to such party of all its responsibilities, duties and liabilities
under this Agreement. Pending appointment of a successor to the Master Servicer
or the Special Servicer hereunder, the Trustee shall act in such capacity as
hereinabove provided. In connection with any such appointment and assumption
described herein, the Trustee may make such arrangements for the compensation of
such successor out of payments on the Mortgage Loans and the REO Properties as
it and such successor shall agree, subject to the terms of this Agreement and/or
the related Co-Lender Agreement limiting the use of funds received in respect of
a Loan Combination to matters related to such Loan Combination; provided,
however, that no such compensation shall be in excess of that permitted the
resigning or terminated party hereunder. Such successor and the other parties
hereto shall take such action, consistent with this Agreement, as shall be
necessary to effectuate any such succession.

         SECTION 7.03. Notification to Certificateholders.

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

         (b) Not later than 10 days after a Responsible Officer of the Trustee
has notice of the occurrence of any event which constitutes or, with notice or
lapse of time or both, would constitute an Event of Default, the Trustee shall
transmit by mail to the Depositor, all the Certificateholders and the Rating
Agencies notice of such occurrence, unless such default shall have been cured.

         SECTION 7.04. Waiver of Events of Default.

         The Holders representing at least 66-2/3% of the Voting Rights
allocated to each Class of Certificates affected by any Event of Default
hereunder may waive such Event of Default; provided, however, that an Event of
Default under any of clauses (i), (ii), (iii), (x) and (xi) of Section 7.01(a)
may

                                     -282-
<PAGE>

be waived only by all of the Certificateholders of the affected Classes. Upon
any such waiver of an Event of Default, such Event of Default shall cease to
exist and shall be deemed to have been remedied for every purpose hereunder
(except as otherwise provided in Section 7.01(d)). No such waiver shall extend
to any subsequent or other Event of Default or impair any right consequent
thereon except to the extent expressly so waived. Notwithstanding any other
provisions of this Agreement, for purposes of waiving any Event of Default
pursuant to this Section 7.04, Certificates registered in the name of the
Depositor or any Affiliate of the Depositor shall be entitled to Voting Rights
with respect to the matters described above.

         SECTION 7.05. Additional Remedies of Trustee Upon Event of Default.

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

                                  ARTICLE VIII

                             CONCERNING THE TRUSTEE

         SECTION 8.01.   Duties of Trustee.

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

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

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

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

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

                  (iii) The Trustee shall not be personally liable with respect
         to any action taken, suffered or omitted to be taken by it in good
         faith in accordance with the terms of this Agreement and the direction
         of the Controlling Class or Holders of Certificates entitled to at

                                     -284-
<PAGE>

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

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

         SECTION 8.02. Certain Matters Affecting Trustee.

         Except as otherwise provided in Section 8.01 and Article X:

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

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

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

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

                  (v) prior to the occurrence of an Event of Default hereunder
         and after the curing of all Events of Default which may have occurred,
         and except as may be provided in Section 10.01 or 10.02, the Trustee
         shall not be bound to make any investigation into the facts or matters
         stated in any resolution, certificate, statement, instrument, opinion,
         report, notice, request, consent, order, approval, bond or other paper
         or document, unless requested in writing to

                                     -285-
<PAGE>

         do so by Holders of Certificates entitled to at least 25% of the Voting
         Rights; provided, however, that if the payment within a reasonable time
         to the Trustee of the costs, expenses or liabilities likely to be
         incurred by it in the making of such investigation is, in the opinion
         of the Trustee, not reasonably assured to the Trustee by the security
         afforded to it by the terms of this Agreement, the Trustee may require
         reasonable indemnity against such expense or liability as a condition
         to taking any such action;

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

                  (vii) the Trustee shall not be responsible for any act or
         omission of the Master Servicer or the Special Servicer (unless the
         Trustee is acting as Master Servicer or the Special Servicer) or the
         Depositor.

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

         The recitals contained herein and in the Certificates, other than the
statements attributed to the Trustee and the Fiscal Agent in Article II and
Section 8.16 and Section 8.18 and the signature of the Certificate Registrar and
the Authenticating Agent set forth on each outstanding Certificate, shall not be
taken as the statements of the Trustee or the Fiscal Agent, and neither the
Trustee nor the Fiscal Agent shall assume any responsibility for their
correctness. Except as expressly set forth in Section 8.16 and 8.18, the Trustee
and the Fiscal Agent make no representations as to the validity or sufficiency
of this Agreement or of any Certificate (other than as to the signature of the
Trustee set forth thereon) or of any Mortgage Loan or related document. The
Trustee and the Fiscal Agent shall not be accountable for the use or application
by the Depositor of any of the Certificates issued to it or of the proceeds of
such Certificates, or for the use or application of any funds paid to the
Depositor in respect of the assignment of the Trust Mortgage Loans to the Trust
Fund, or any funds deposited in or withdrawn from a Custodial Account or any
other account by or on behalf of the Depositor, the Master Servicer or the
Special Servicer. The Trustee and the Fiscal Agent shall not be responsible for
the accuracy or content of any resolution, certificate, statement, opinion,
report, document, order or other instrument furnished by the Depositor, the
Master Servicer or the Special Servicer, and accepted by the Trustee in good
faith, pursuant to this Agreement.

         SECTION 8.04. Trustee and Fiscal Agent May Own Certificates.

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

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

         (a) On each Distribution Date, the Trustee shall withdraw from the
general funds on deposit in the Collection Account, prior to any distributions
to be made therefrom on such date, and pay

                                     -286-
<PAGE>

to itself the Trustee Fee for such Distribution Date and, to the extent not
previously paid, for all prior Distribution Dates, as compensation for all
services rendered by the Trustee in the execution of the trusts hereby created
and in the exercise and performance of any of the powers and duties of the
Trustee hereunder. The Trustee Fees (which shall not be limited by any provision
of law in regard to the compensation of a trustee of an express trust) shall
constitute the Trustee's sole compensation for such services to be rendered by
it.

         (b) The Trustee and any director, officer, employee or agent of the
Trustee shall be entitled to be indemnified for and held harmless by the Trust
Fund out of the Pool Custodial Account and the Collection Account (and, to the
extent that a Loan Combination or any related REO Property is affected, by the
Trust Fund and/or the related Non-Trust Mortgage Loan Noteholder(s) out of the
related Loan Combination Custodial Account) against any loss, liability or
reasonable "out-of-pocket" expense (including costs and expenses incurred in
connection with removal of the Special Servicer and Master Servicer pursuant to
Sections 7.01 and 7.02, costs and expenses of litigation, and of investigation,
counsel fees, damages, judgments and amounts paid in settlement) arising out of,
or incurred in connection with, this Agreement or the Certificates ("Trustee
Liability"); provided that such loss, liability or expense constitutes an
"unanticipated expense" within the meaning of Treasury regulations section
1.860G-1(b)(3)(ii); and provided, further, that neither the Trustee nor any of
the other above specified Persons shall be entitled to indemnification pursuant
to this Section 8.05(b) for (1) any liability specifically required to be borne
thereby pursuant to the terms of this Agreement, or (2) any loss, liability or
expense incurred by reason of willful misfeasance, bad faith or negligence in
the performance of, or the negligent disregard of, the Trustee's obligations and
duties hereunder, or as may arise from a breach of any representation, warranty
or covenant of the Trustee made herein, or (3) any loss, liability or expense
that constitutes allocable overhead. The provisions of this Section 8.05(b) and
of Section 8.05(c) shall survive any resignation or removal of the Trustee and
appointment of a successor trustee.

         (c) If the Trustee Liability arises from the issuance or sale of the
Certificates and the indemnification provided for in Section 8.05(b) is invalid
or unenforceable, then the Trust Fund shall contribute to the amount paid or
payable by the Trustee as a result of such Trustee Liability in such proportion
as is appropriate to reflect the relative fault of any of the other parties on
the one hand and the Trustee on the other in connection with the actions or
omissions which resulted in such Trustee Liability, as well as any other
relevant equitable considerations.

         (d) The Trustee shall indemnify and hold harmless the Trust Fund
against any losses arising out of any errors made solely by the Trustee in
calculating distributions to be made hereunder and any other calculation or
reporting hereunder (in each case not attributable to information provided to
the Trustee by the Master Servicer or the Special Servicer); provided that such
loss arose by reason of willful misfeasance, bad faith or negligence on the part
of the Trustee. The provisions of this Section 8.05(d) shall survive any
resignation or removal of the Trustee and appointment of a successor trustee.

         SECTION 8.06. Eligibility Requirements for Trustee.

         (a) The Trustee hereunder shall at all times be a bank, a trust
company, an association or a corporation organized and doing business under the
laws of the United States of America or any state thereof or the District of
Columbia, authorized under such laws to exercise trust powers, having a combined
capital and surplus of at least $50,000,000 and subject to supervision or
examination by federal or state banking authority. If such bank, trust company,
association or corporation publishes

                                     -287-
<PAGE>

reports of condition at least annually, pursuant to law or to the requirements
of the aforesaid supervising or examining authority, then for the purposes of
this section the combined capital and surplus of such bank, trust company,
association or corporation shall be deemed to be its combined capital and
surplus as set forth in its most recent report of condition so published. The
Trustee shall at all times maintain a long-term unsecured debt rating of at
least (a) "AA-" from S&P (or "A+" from S&P, if the Trustee's short-term
unsecured debt rating is at least "A-1" by S&P) and "Aa3" from Moody's, or (b)
in the case of either Rating Agency, (i) "A-" from S&P and "A3" from Moody's, if
a Fiscal Agent meeting the requirements of Section 8.17(a) is then currently
acting in such capacity, or (ii) such other rating as shall not result in an
Adverse Rating Event with respect to any Class of Certificates, as confirmed in
writing by such Rating Agency. The Trustee's acting in such capacity shall not
adversely affect the application of the Prohibited Transaction Exemption to the
Investment Grade Certificates. If at any time the Trustee shall cease to be
eligible in accordance with the provisions of this section, the Trustee shall
resign immediately in the manner and with the effect specified in Section 8.07;
provided that if the Trustee shall cease to be so eligible because its combined
capital and surplus is no longer at least $50,000,000 or its long-term unsecured
debt rating no longer conforms to the requirements of the immediately preceding
sentence, and if the Trustee proposes to the other parties hereto to enter into
an agreement with (and reasonably acceptable to) each of them, and if in light
of such agreement the Trustee's continuing to act in such capacity would not (as
evidenced in writing by each Rating Agency) cause an Adverse Rating Event with
respect to any Class of Certificates, then upon the execution and delivery of
such agreement the Trustee shall not be required to resign, and may continue in
such capacity, for so long as none of the ratings assigned by the Rating
Agencies to the Certificates is adversely affected thereby. The bank, trust
company, corporation or association serving as Trustee may have normal banking
and trust relationships with the Depositor, the Master Servicer, the Special
Servicer and their respective Affiliates.

         SECTION 8.07. Resignation and Removal of Trustee.

         (a) The Trustee may at any time resign and be discharged from the
trusts hereby created by giving written notice thereof to the Depositor, the
Master Servicer, the Special Servicer, all Certificateholders and all Non-Trust
Mortgage Loan Noteholders. Upon receiving such notice of resignation, the
Depositor shall promptly appoint a successor trustee acceptable to the Depositor
by written instrument, in duplicate, which instrument shall be delivered to the
resigning Trustee and to the successor trustee. A copy of such instrument shall
be delivered to the Master Servicer, the Special Servicer, the
Certificateholders and the Non-Trust Mortgage Loan Noteholders by the Depositor.
If no successor trustee shall have been so appointed and have accepted
appointment within 30 days after the giving of such notice of resignation, the
resigning Trustee may petition any court of competent jurisdiction for the
appointment of a successor trustee.

         (b) If at any time the Trustee shall cease to be eligible in accordance
with the provisions of Section 8.06 and shall fail to resign after written
request therefor by the Depositor, or if at any time the Trustee shall become
incapable of acting, or shall be adjudged bankrupt or insolvent, or a receiver
of the Trustee or of its property 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, or if the Trustee
shall fail (other than by reason of the failure of either the Master Servicer or
the Special Servicer to timely perform its obligations hereunder or as a result
of other circumstances beyond the Trustee's reasonable control) to timely
deliver or otherwise make available in accordance with this Agreement any
current or revised Distribution Date Statement, CMSA Loan Periodic Update

                                     -288-
<PAGE>

File, CMSA Property File, CMSA Financial File or other report or statement
required by Section 4.02 and such failure shall continue unremedied for a period
of five days after receipt of written notice by the Trustee of such failure, or
if a tax is imposed or threatened with respect to the Trust Fund by any state in
which the Trustee is located or in which it holds any portion of the Trust Fund,
then the Depositor may remove the Trustee and appoint a successor trustee
acceptable to the Depositor and the Master Servicer by written instrument, in
duplicate, which instrument shall be delivered to the Trustee so removed and to
the successor trustee. A copy of such instrument shall be delivered to the
Master Servicer, the Special Servicer, the Certificateholders and the Non-Trust
Mortgage Loan Noteholders by the successor trustee so appointed.

         (c) The Holders of Certificates entitled to 51% of the Voting Rights
may at any time remove the Trustee and appoint a successor trustee by written
instrument or instruments, signed by such Holders or their attorneys-in-fact
duly authorized, one complete set of which instruments shall be delivered to the
Master Servicer, one complete set to the Trustee so removed and one complete set
to the successor trustee so appointed. A copy of such instrument shall be
delivered to the Depositor, the Special Servicer, the remaining
Certificateholders and the Non-Trust Mortgage Loan Noteholders by the successor
trustee so appointed.

         (d) In the event that the Trustee is terminated or removed pursuant to
this Section 8.07, all of its and any corresponding Fiscal Agent's rights and
obligations under this Agreement and in and to the Mortgage Loans shall be
terminated, other than any rights or obligations that accrued prior to the date
of such termination or removal (including the right to receive all fees,
expenses and other amounts (including P&I Advances and any accrued interest
thereon) accrued or owing to it under this Agreement, with respect to periods
prior to the date of such termination or removal, and no termination without
cause shall be effective until the payment of such amounts to the Trustee and
such Fiscal Agent).

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

         SECTION 8.08. Successor Trustee.

         (a) Any successor trustee appointed as provided in Section 8.07 shall
execute, acknowledge and deliver to the Depositor, the Master Servicer, the
Special Servicer and to the predecessor trustee an instrument accepting such
appointment hereunder and thereupon the resignation or removal of the
predecessor trustee shall become effective and such successor trustee, without
any further act, deed or conveyance, shall become fully vested with all the
rights, powers, duties and obligations of its predecessor hereunder, with the
like effect as if originally named as trustee herein. The predecessor trustee
shall deliver to the successor trustee (at the expense of the Certificateholders
that effected the removal, if the Trustee has been removed in accordance with
Section 8.07(c) without cause or if such expenses are not paid by such
Certificateholders within ninety (90) days after they are incurred, at the
expense of the Trust, provided that such Certificateholders shall remain liable
to the Trust for such expenses) all Mortgage Files and related documents and
statements held by it hereunder (other than any Mortgage Files at the time held
on its behalf by a third-party Custodian, which Custodian shall become the agent
of the successor trustee), and the Depositor, the Master Servicer, the Special
Servicer and the predecessor trustee shall execute and deliver such instruments
and do such

                                     -289-
<PAGE>

other things as may reasonably be required to more fully and certainly vest and
confirm in the successor trustee all such rights, powers, duties and
obligations, and to enable the successor trustee to perform its obligations
hereunder.

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

         (c) Upon acceptance of appointment by a successor trustee as provided
in this Section 8.08, such successor trustee shall mail notice of the succession
of such trustee hereunder to the Depositor, the Master Servicer, the Special
Servicer, the Certificateholders and the Non-Trust Mortgage Loan Noteholders.

         SECTION 8.09. Merger or Consolidation of Trustee and Fiscal Agent.

         Any entity into which the Trustee or the Fiscal Agent may be merged or
converted, or with which the Trustee or the Fiscal Agent may be consolidated, or
any entity resulting from any merger, conversion or consolidation to which the
Trustee or the Fiscal Agent shall be a party, or any entity succeeding to the
corporate trust business of the Trustee, shall be the successor of the Trustee
or the Fiscal Agent, as the case may be, hereunder, provided such entity shall
be eligible under the provisions of Section 8.06 or Section 8.17, as applicable,
without the execution or filing of any paper or any further act on the part of
any of the parties hereto, anything herein to the contrary notwithstanding.

         SECTION 8.10. Appointment of Co-Trustee or Separate Trustee.

         (a) Notwithstanding any other provisions hereof, at any time, for the
purpose of meeting any legal requirements of any jurisdiction in which any part
of the Trust Fund or property securing the same may at the time be located, the
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 the Trust Fund, and to vest in such Person or Persons, in
such capacity, such title to the Trust Fund, or any part thereof, and, subject
to the other provisions of this Section 8.10, such powers, duties, obligations,
rights and trusts as the Master Servicer and the Trustee may consider necessary
or desirable. No co-trustee or separate trustee hereunder shall be required to
meet the terms of eligibility as a successor trustee under Section 8.06
hereunder and no notice to Holders of Certificates of the appointment of
co-trustee(s) or separate trustee(s) shall be required under Section 8.08
hereof.

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

                                     -290-
<PAGE>

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

         (d) Any separate trustee or co-trustee may, at any time, constitute the
Trustee, its agent or attorney-in-fact, with full power and authority, to the
extent not prohibited by law, to do any lawful act under or in respect of this
Agreement on its behalf and in its name. If any separate trustee or co-trustee
shall die, become incapable of acting, resign or be removed, all of its estates,
properties, rights, remedies and trusts vested therein pursuant to the
applicable instrument of appointment and this Section 8.10, shall vest in and be
exercised by the Trustee, to the extent permitted by law, without the
appointment of a new or successor trustee.

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

         SECTION 8.11. Appointment of Custodians.

         The Trustee may appoint at the Trustee's expense one or more Custodians
to hold all or a portion of the Mortgage Files as agent for the Trustee. Each
Custodian shall be a depository institution supervised and regulated by a
federal or state banking authority, shall have combined capital and surplus of
at least $10,000,000, shall be qualified to do business in the jurisdiction in
which it holds any Mortgage File and shall not be the Depositor, any Mortgage
Loan Seller or any Affiliate of any of them. Neither the Master Servicer nor the
Special Servicer shall have any duty to verify that any such Custodian is
qualified to act as such in accordance with the preceding sentence. The Trustee
may enter into agreements to appoint a Custodian which is not the Trustee,
provided that such agreement: (i) is consistent with this Agreement in all
material respects and requires the Custodian to comply with all of the
applicable conditions of this Agreement; (ii) provides that if the Trustee shall
for any reason no longer act in the capacity of Trustee hereunder, the successor
Trustee or its designee may thereupon assume all of the rights and, except to
the extent they arose prior to the date of assumption, obligations of the
Custodian under such agreement or, alternatively, may terminate such agreement
without cause and without payment of any penalty or termination fee; and (iii)
does not permit the Custodian any rights of indemnification that may be
satisfied out of assets of the Trust Fund. The appointment of one or more
Custodians shall not relieve the Trustee from any of its obligations hereunder,
and the Trustee shall remain responsible for all acts and omissions of any
Custodian. In the absence of any other Person appointed in accordance herewith
acting as Custodian, the Trustee agrees to act in such capacity in accordance
with the terms hereof. Notwithstanding anything herein to the contrary, if the
Trustee is no longer the Custodian, any provision or requirement herein
requiring notice or any information or documentation to be provided to the
Custodian shall be construed to require that such notice, information or
documents also be provided to the Trustee. Any Custodian hereunder shall at all
times maintain a fidelity bond and errors and omissions policy in amounts
customary for custodians performing duties similar to those set forth in this
Agreement and, in any event, satisfying the same

                                     -291-
<PAGE>

requirements (including as to the insurer) as are applicable to any such bond or
policy required to be maintained by the Master Servicer pursuant to Section
3.07. Any engagement of a third party to act as Custodian with respect to the
Mortgage File or any portion thereof with respect to a Loan Combination shall be
subject to Section 2.02(b) of the related Co-Lender Agreement.

         SECTION 8.12. Appointment of Authenticating Agents.

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

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

         (c) Any Authenticating Agent appointed in accordance with this Section
8.12 may at any time resign by giving at least 30 days' advance written notice
of resignation to the Trustee, the Master Servicer, the Special Servicer and the
Depositor. The Trustee may at any time terminate the agency of any
Authenticating Agent appointed in accordance with this Section 8.12 by giving
written notice of termination to such Authenticating Agent, the Master Servicer
and the Depositor. Upon receiving a notice of such a resignation or upon such a
termination, or in case at any time any Authenticating Agent shall cease to be
eligible in accordance with the provisions of this Section 8.12, the Trustee may
appoint a successor Authenticating Agent, in which case the Trustee shall give
written notice of such appointment to the Master Servicer, the Certificate
Registrar and the Depositor and shall mail notice of such appointment to all
Holders of Certificates; provided, however, that no successor Authenticating
Agent shall be appointed unless eligible under the provisions of this Section
8.12. Any successor Authenticating Agent upon acceptance of its appointment
hereunder shall become vested with all the rights, powers, duties and
responsibilities of its predecessor hereunder, with like effect as if originally
named as Authenticating Agent.

         SECTION 8.13. Appointment of Tax Administrators.

         (a) The Trustee may appoint at the Trustee's expense any Person with
appropriate tax-related experience to act as Tax Administrator hereunder;
provided that, in the absence of any other Person appointed in accordance
herewith acting as Tax Administrator, the Trustee agrees to act in such capacity
in accordance with the terms hereof. The appointment of a Tax Administrator
shall not relieve the Trustee from any of its obligations hereunder, and the
Trustee shall remain responsible for all acts and omissions of the Tax
Administrator. The Trustee shall cause any such Tax Administrator appointed by
it to execute and deliver to the Trustee an instrument in which such Tax
Administrator shall agree to act in such capacity, with the obligations and
responsibilities herein.

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

         (c) Any Tax Administrator appointed in accordance with this Section
8.13 may at any time resign by giving at least 30 days' advance written notice
of resignation to the Trustee, the Master Servicer, the Special Servicer and the
Depositor. The Trustee may at any time terminate the agency of any Tax
Administrator appointed in accordance with this Section 8.13 by giving written
notice of termination to such Tax Administrator, the Master Servicer, and the
Depositor. Upon receiving a notice of such a resignation or upon such a
termination, or in case at any time any Tax Administrator shall cease to be
eligible in accordance with the provisions of this Section 8.13, the Trustee may
appoint a successor Tax Administrator, in which case the Trustee shall give
written notice of such appointment to the Master Servicer, the Special Servicer
and the Depositor and shall mail notice of such appointment to all Holders of
Certificates; provided, however, that no successor Tax Administrator shall be
appointed unless eligible under the provisions of this Section 8.13. Any
successor Tax Administrator upon acceptance of its appointment hereunder shall
become vested with all the rights, powers, duties and responsibilities of its
predecessor hereunder, with like effect as if originally named as Tax
Administrator.

         SECTION 8.14. Access to Certain Information.

         (a) The Trustee shall afford to the Master Servicer, the Special
Servicer and the Depositor, and to the OTS, the FDIC and any other banking or
insurance regulatory authority that may exercise authority over any
Certificateholder or Certificate Owner, access to any documentation regarding
the Trust Mortgage Loans within its control that may be required to be provided

provided that (x) the Trustee shall not have any responsibility to file any
items (other than those generated by it) that have not been received in a format

referred to as the "Subsequent Exchange Act Reports". The Trustee shall have no
liability to the Certificateholders or the Trust with respect to any failure to
properly prepare or file any of the Subsequent Exchange Act Reports to the
extent that such failure is not the result of any negligence, bad faith or
willful misconduct on its part.

         (b) At all times during the Trust's fiscal year 2004 (and, if as of the
beginning of any other fiscal year for the Trust, the Registered Certificates

         Mortgage Loan or an REO Property, which acquisition or disposition has
         not otherwise been reflected in the Distribution Date Statements filed
         with the Commission or has not otherwise been reported to the Depositor
         pursuant to any other section of this Agreement;

         significant amount of assets (other than Permitted Investments, Trust
         Mortgage Loans and REO Properties), other than in the normal course of
         business, which acquisition or disposition has not otherwise been
         reflected in the Distribution Date Statements filed with the Commission
         or has not otherwise been reported to the Depositor pursuant to any
         other section of this Agreement;

         included in the Trust Fund is subject, or any threat by a governmental
         authority to bring any such legal proceedings;

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

                  (vii) any change in the rating or ratings assigned to any
         Class of Certificates not otherwise reflected in the Distribution Date
         Statements filed with the Commission;

provided that (1) the actual knowledge of a Responsible Officer of the Trustee
of any material legal proceedings of which property included in the Trust Fund
is subject or of any material legal proceedings threatened by a governmental
authority is limited (except where the Trustee received information regarding
such proceeding from the Master Servicer or the Special Servicer pursuant to the
next paragraph) to circumstances where it would be reasonable for the Trustee to
identify such property as an asset of, or as securing an asset of, the Trust or
such threatened proceedings as concerning the Trust and (2) no Responsible
Officer of the Trustee shall be deemed to have actual knowledge of the matters
described in clauses (vi) and (vii) of this Section 8.15(b) unless (x) any such
matter contemplated in clause (vi) occurred or related specifically to the Trust
or (y) such Responsible Officer was notified in a written instrument addressed
to it.

         Further, each other party to this agreement shall promptly notify the
Trustee of the occurrence or existence of any of the forgoing matters in this
Section 8.15(b) of which a Servicing Officer (in the case of the Master Servicer
or the Special Servicer), a Responsible Officer (in the case of the Fiscal
Agent) or a senior officer (in the case of the Depositor) thereof has actual
knowledge.

         (c) If as of the beginning of any fiscal year for the Trust (other than
fiscal year 2004), the Registered Certificates are held (directly or, in the
case of Registered Certificates held in book-entry form, through the Depository)
by less than 300 Holders and/or Depository Participants having accounts with the
Depository, the Trustee shall, in accordance with the Exchange Act and the rules
and regulations promulgated thereunder, timely file a Form 15 with respect to
the Trust suspending all reporting requirements under the Exchange Act.

         (d) As and to the extent required by the Sarbanes-Oxley Act of 2002
(the "Sarbanes-Oxley Act") and the rules adopted by the Commission with respect
thereto, all Annual Reports on Form 10-K filed with the Commission shall include
such certification as complies in form and substance with the Sarbanes-Oxley Act
and the rules and regulations promulgated thereunder (such certification, the
"Sarbanes-Oxley Certification"; any party hereto whose officer is to sign, in
accordance with the Sarbanes-Oxley Act and the rules and regulations promulgated
thereunder, any Sarbanes-Oxley Certification with respect to the Trust, a
"Certifying Party"; and any officer who is to sign, in accordance with the
Sarbanes-Oxley Act and the rules and regulations promulgated thereunder, any
Sarbanes-Oxley Certification, a "Certifying Officer"). Upon request of any
Rating Agency, the Trustee shall deliver a copy of such Sarbanes-Oxley
Certification to such Rating Agency.

         (e) Any of the Depositor, the Trustee or the Master Servicer may be the
Certifying Party with respect to a Sarbanes-Oxley Certification filed as part of
an Annual Report on Form 10-K relating to the Trust; provided that no officer of
either the Trustee or the Master Servicer shall be responsible for being the
sole signatory of any Sarbanes-Oxley Certification to be filed in connection
with the Trust. In connection with the filing of any Annual Report on Form 10-K
with respect to the Trust as contemplated by Section 8.15(a), the Certifying
Party shall, no later than 10 days prior to the date on which the Trustee has
indicated its intention to file such report, cause its Certifying Officer to
execute and deliver to the Trustee, with respect to the Trust, for filing with
such Annual Report on Form 10-K, the Sarbanes-Oxley Certification that is to be
included as part of such Annual Report on Form 10-K.

         (f) No later than five (5) Business Days (or, in the case of an Annual
Report on Form 10-K, 20 days) prior to any filing of a Subsequent Exchange Act
Report that is to be made with respect to the Trust as contemplated by Section
8.15(a), the Trustee shall deliver a copy of such report, together with all
exhibits thereto, for review by the Depositor and the Special Servicer. Promptly
upon receipt of any such report and the accompanying exhibits, the Depositor and
the Special Servicer shall promptly (and in any event within two (2) Business
Days) review such report and the accompanying exhibits and notify the Trustee of
any material misstatements or omissions relating thereto that come to its
attention, which material misstatements or omissions the Trustee shall correct

Master Servicer and the Special Servicer) prior to the filing of such report and
the accompanying exhibits.

         (g) No later than 10 days prior to the date on which the Trustee has
indicated its intention to file any Annual Report on Form 10-K with respect to
the Trust (but no earlier than March 20 of the year in which such Annual Report

the Trustee shall cause the appropriate officer of the Trustee (i.e., the
officer thereof that would have qualified as a Certifying Officer) to execute
and deliver to each Certifying Party and Certifying Officer a certification (a
"Trustee Backup Certification"), which Trustee Backup Certification shall be in
the form of Exhibit P attached hereto. The Trustee shall indemnify and hold
harmless each Certifying Party and Certifying Officer to whom it delivers any
Trustee Backup Certification for all losses, liabilities, claims, damages, costs
and expenses (including reasonable attorneys' fees and expenses) resulting from
a breach of any certification made in such Trustee Backup Certification, as well
as any other losses, claims, damages, costs and expenses (including reasonable
attorneys' fees and expenses) incurred by such Certifying Party or Certifying
Officer, as the case may be, in connection with the execution and delivery of
the subject Sarbanes-Oxley Certification resulting from the negligence, bad
faith or willful misfeasance of the Trustee in connection with the performance
by the Trustee of its duties hereunder.

         (h) No later than 10 days prior to the date on which the Trustee has
indicated its intention to file any Annual Report on Form 10-K with respect to
the Trust (but no earlier than March 20 of the year in which such Annual Report
on Form 10-K is to be filed), unless the Master Servicer is to be the Certifying
Party, the Master Servicer shall cause the appropriate officer of the Master
Servicer (i.e., the officer thereof that would have qualified as a Certifying
Party) to execute and deliver to each Certifying Party and Certifying Officer a
certification (a "Master Servicer Backup Certification"), which Master Servicer
Backup Certification shall be in the form of Exhibit Q attached hereto. The
Master Servicer shall indemnify and hold harmless each Certifying Party and
Certifying Officer to whom it delivers any Master Servicer Backup Certification
for all losses, liabilities, claims, damages, costs and

                                     -298-

expenses (including reasonable attorneys' fees and expenses) resulting from a
breach of any certification made in such Master Servicer Backup Certification,
as well as any other losses, claims, damages, costs and expenses (including
reasonable attorneys' fees and expenses) incurred by such Certifying Party or
Certifying Officer, as the case may be, in connection with the execution and
delivery of the subject Sarbanes-Oxley Certification, in each case, resulting
from the negligence, bad faith or willful misfeasance of the Master Servicer in
connection with the performance by the Master Servicer of its duties hereunder.

         (i) No later than 10 days prior to the date on which the Trustee has

appropriate officer of the Special Servicer (i.e., the officer thereof that
would have qualified as a Certifying Party) to execute and deliver to each
Certifying Party and Certifying Officer a certification (a "Special Servicer
Backup Certification"), which Special Servicer Backup Certification shall be in
the form of Exhibit R attached hereto. The Special Servicer shall indemnify and
hold harmless each Certifying Party and Certifying Officer to whom it delivers

damages, costs and expenses (including reasonable attorneys' fees and expenses)
resulting from a breach of any certification made in such Special Servicer
Backup Certification, as well as any other losses, claims, damages, costs and
expenses (including reasonable attorneys' fees and expenses) incurred by such

the execution and delivery of the subject Sarbanes-Oxley Certification resulting
from the negligence, bad faith or willful misfeasance of the Special Servicer in
connection with the performance by the Special Servicer of its duties hereunder.

         (j) No later than 10 days prior to the date on which the Trustee has
indicated its intention to file the Annual Report on Form 10-K with respect to
the Trust for fiscal year 2004, unless the Depositor is to be the Certifying
Party, the Depositor shall cause an officer of the Depositor to execute and
deliver to each Certifying Party and Certifying Officer a certification (a
"Depositor Backup Certification"), which Depositor Backup Certification shall be
in a form mutually acceptable to the Certifying Party and the Depositor. The

Person reasonably believes to be appropriate in order to allow it to deliver any
Sarbanes-Oxley Certification or portion thereof with respect to the Trust.

         (l) Unless the other parties hereto receive written notice from the
Trustee to the contrary, the Trustee hereby certifies that it intends to file
any Annual Report on Form 10-K with respect to the Trust for any particular
fiscal year on the last Business Day that is not more than 90 days following the

clarify or amend any provision of this Section 8.15, this Agreement shall be
amended to reflect the new agreement between the parties covering matters in

         (a) The Trustee hereby represents and warrants to the Master Servicer,

         Trustee, and the performance and compliance with the terms of this
         Agreement by the Trustee, will not violate the Trustee's organizational
         documents or constitute a default (or an event which, with notice or
         lapse of time, or both, would constitute a default) under, or result in
         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) Except to the extent that the laws of certain
         jurisdictions in which any part of the Trust Fund may be located

         of equity, regardless of whether such enforcement is considered in a
         proceeding in equity or at law.

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

                  (vi) No litigation is pending or, to the best of the Trustee's
         knowledge, threatened against the Trustee that, if determined adversely
         to the Trustee, would prohibit the Trustee from entering into this

         likely to materially and adversely affect either the ability of the
         Trustee to perform its obligations under this Agreement or the
         financial condition of the Trustee.

                  (vii) Any consent, approval, authorization or order of any
         court or governmental agency or body required for the execution,
         delivery and performance by the Trustee of or compliance by the Trustee
         with this Agreement, or the consummation of the transactions
         contemplated by this Agreement, has been obtained and is effective,
         except where the lack of consent, approval, authorization or order
         would not have a material adverse effect on the performance by the
         Trustee under this Agreement.

                  (viii) The Trustee is eligible to act as trustee hereunder in
         accordance with Section 8.06.

shall inure to the benefit of the Persons for whose benefit they were made for
so long as the Trust Fund remains in existence. Upon discovery by any party
hereto of any breach of any of the foregoing representations, warranties and
covenants, the party discovering such breach shall give prompt written notice
thereof to the other parties hereto.

         (c) Any successor Trustee shall be deemed to have made, as of the date
of its succession, each of the representations and warranties set forth in
Section 8.16(a), subject to such appropriate modifications to the representation

successor's jurisdiction of organization and whether it is a corporation,
partnership, bank, association or other type of organization.

         SECTION 8.17. The Fiscal Agent.

         (a) The Fiscal Agent shall at all times maintain a long-term unsecured
debt rating of no less than "AA-" from S&P (or "A+" from S&P, if the Fiscal
Agent's short-term unsecured debt rating is at least "A-1" by S&P) and "Aa3"
from Moody's, or, in the case of either Rating Agency, such other rating as
shall not result in an Adverse Rating Event with respect to any Class of
Certificates, as confirmed in writing by such Rating Agency.

         (b) To the extent that the Trustee is required, pursuant to the terms
of this Agreement, to make any Advance, whether as successor master servicer or
otherwise, and has failed to do so in accordance with the terms hereof, the
Fiscal Agent shall make such Advance when and as required by the terms of this
Agreement on behalf the Trustee as if the Fiscal Agent were the Trustee
hereunder. To the extent that the Fiscal Agent makes an Advance pursuant to this
Section 8.17(b) or otherwise pursuant to this Agreement, the obligations of the
Trustee under this Agreement in respect of such Advance shall be satisfied.
Notwithstanding anything contained in this Agreement to the contrary, the Fiscal
Agent shall be entitled to all limitations on liability, rights of reimbursement
and indemnities that the Trustee is entitled to hereunder as if it were the
Trustee.

owed to the Fiscal Agent in respect of unreimbursed Advances) incurred by the
Fiscal Agent in connection with the transactions contemplated by this Agreement
shall be borne by the Trustee, and neither the Trustee nor the Fiscal Agent
shall be entitled to reimbursement therefor from any of the Trust Fund, the
Depositor, the Master Servicer or the Special Servicer.

         (d) The obligations of the Fiscal Agent set forth in this Section 8.17
or otherwise pursuant to this Agreement shall exist only for so long as the
Trustee that appointed it (or, in the case of the initial Fiscal Agent, so long
as the initial Trustee) shall act as Trustee hereunder. The Fiscal Agent may
resign or be removed by the Trustee only if and when the existence of such
Fiscal Agent is no longer necessary for such Trustee to satisfy the eligibility
requirements of Section 8.06; provided that the Fiscal Agent shall be deemed to
have resigned at such time as the Trustee that appointed it (or, in the case of
the initial Fiscal Agent, at such time as the initial Trustee) resigns or is
removed as Trustee hereunder (in which case the responsibility for appointing a
successor Fiscal Agent shall belong to the successor Trustee, and which
appointment the successor Trustee shall use its best efforts to make, insofar as
such appointment is necessary for such successor Trustee to satisfy the
eligibility requirements of Section 8.06). Any successor fiscal agent so
appointed shall be required to execute and deliver to the other parties hereto a
written agreement to assume and perform the duties of the Fiscal Agent set forth
in this Agreement; provided that no such successor shall become Fiscal Agent
hereunder unless either (i) it satisfies the rating requirements of Section
8.17(a) or (ii) the Trustee shall have received written confirmation from each
Rating Agency that the succession of such proposed successor fiscal agent would
not, in and of itself, result in an Adverse Rating Event with respect to any
Class of Certificates.

         (e) The Trustee shall promptly notify the other parties hereto, the
Certificateholders and the Non-Trust Mortgage Loan Noteholders in writing of the
appointment, resignation or removal of any Fiscal Agent.

         SECTION 8.18. Representations and Warranties of Fiscal Agent.

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

                  (iii) The Fiscal Agent 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

         bankruptcy, insolvency, reorganization, moratorium and other laws

         regulation or demand of any federal, state or local governmental or
         regulatory authority, which violation, in the Fiscal Agent's good faith
         and reasonable judgment, is likely to affect materially and adversely
         either the ability of the Fiscal Agent to perform its obligations under
         this Agreement or the financial condition of the Fiscal Agent.

                  (vi) No litigation is pending or, to the best of the Fiscal
         Agent's knowledge, threatened against the Fiscal Agent that, if

         transactions contemplated by this Agreement, has been obtained and is
         effective, except where the lack of consent, approval, authorization or

provided that, if any Trust Mortgage Loan purchased pursuant to this Section
9.01 is part of a Loan Combination, then the release, endorsement or assignment
of the documents constituting the related Mortgage File and Servicing File shall

Loans pursuant to this paragraph, except in the case of the GIC Office Trust
Mortgage Loan or the MGM Tower Trust Mortgage Loan, shall be on a

copy of which writing shall be delivered to the Trustee), shall have the right,
with the consent of the Master Servicer, to exchange all of the Certificates for
all of the Trust Mortgage Loans and each REO Property remaining in the Trust
Fund as contemplated by clause (i)(B) of the first paragraph of this Section
9.01(a), by giving written notice to all the parties hereto and the Non-Trust
Mortgage Loan Noteholders no later than 60 days prior to the anticipated date of

Properties relates to a Loan Combination. In the event that all the
Certificateholders elect (as evidenced by a writing signed by each
Certificateholder and delivered to the Trustee) to exchange all of the
Certificates for all of the Trust Mortgage Loans and, subject to the proviso to
the preceding sentence, each REO Property remaining in the Trust Fund, the
Certificateholders, not later than the fifth Business Day preceding the

already on deposit in such Custodial Account and (ii) pay to the Trustee an
amount, in immediately available funds, equal to $5,000.00. In addition, on the
Trust Master Servicer Remittance Date immediately preceding the Final

Remittance Date from the Pool Custodial Account pursuant to the first paragraph
of Section 3.04(b), together with any other amounts on deposit in the Pool
Custodial Account that would otherwise be held for future distribution. Upon
confirmation that such final deposits have been made and following the surrender

(each Certificateholder having agreed to such designation in a writing delivered
to the Trustee), the Mortgage Files for the remaining Trust Mortgage Loans and
REO Properties and shall execute all assignments, endorsements and other
instruments furnished to it by the Certificateholders as shall be necessary to
effectuate transfer of the Trust Mortgage Loans and REO Properties remaining in
the Trust Fund; provided that, if any Trust Mortgage Loan exchanged pursuant to
this Section 9.01 is part of a Loan Combination, then the release, endorsement
or assignment of the documents constituting the related Mortgage File and
Servicing File shall be in the manner contemplated by Section 3.25. Any transfer
of Trust Mortgage Loans pursuant to this paragraph, except in the case of the
GIC Office Trust Mortgage Loan or the MGM Tower Trust Mortgage Loan, shall be on
a servicing-released basis.

         Notice of any termination shall be given promptly by the Trustee by
letter to Certificateholders and the Non-Trust Mortgage Loan Noteholders mailed

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

         Upon presentation and surrender of the Certificates by the
Certificateholders on the Final Distribution Date, the Trustee shall distribute
to each Certificateholder so presenting and surrendering its Certificates such
Certificateholder's Percentage Interest of that portion of the amounts then on
deposit in the Collection Account that are allocable to payments on the Class of
Certificates so presented and surrendered. Amounts on deposit in the Collection
Account as of the Final Distribution Date, up to the Available Distribution
Amount for the Final Distribution Date, shall be allocated for the following

         (g) Within 30 days after the Closing Date, the Tax Administrator shall
prepare and file with the IRS Form 8811, "Information Return for Real Estate
Mortgage Investment Conduits (REMIC) and Issuers of Collateralized Debt
Obligations" for the Trust Fund. In addition, the Tax Administrator shall
prepare, sign and file all of the other Tax Returns in respect of each REMIC
Pool. The expenses of preparing and filing such returns shall be borne by the
Tax Administrator without any right of reimbursement therefor. The other parties
hereto shall provide on a timely basis to the Tax Administrator or its designee
such information with respect to each REMIC Pool as is in its possession and
reasonably requested by the Tax Administrator to enable it to perform its
obligations under this Section 10.01. Without limiting the generality of the
foregoing, the Depositor, within ten days following the Tax Administrator's
request therefor, shall provide in writing to the Tax Administrator such
information as is reasonably requested by the Tax Administrator for tax
purposes, as to the valuations and issue prices of the Certificates, and the Tax
Administrator's duty to perform its reporting and other tax compliance
obligations under this Section 10.01 shall be subject to the condition that it
receives from the Depositor such information possessed by the Depositor that is
necessary to permit the Tax Administrator to perform such obligations.

         (h) The Tax Administrator shall perform on behalf of each REMIC Pool
all reporting and other tax compliance duties that are the responsibility of
each such REMIC Pool under the Code, the REMIC Provisions or other compliance
guidance issued by the IRS or any state or local taxing authority. Included
among such duties, the Tax Administrator shall provide to: (i) any Transferor of
a Residual Interest Certificate, such information as is necessary for the
application of any tax relating to the transfer of a Residual Interest
Certificate to any Person who is not a Permitted Transferee; (ii) the
Certificateholders, such information or reports as are required by the Code or
the REMIC Provisions, including reports relating to interest, original issue
discount and market discount or premium (using the Prepayment Assumption as
required hereunder); and (iii) the IRS, the name, title, address and telephone
number of the Person who will serve as the representative of each REMIC Pool.

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

                                     -315-
<PAGE>

written advice, and the cost of same shall be borne by the party seeking to take
the action not permitted by this Agreement, but in no event at the cost or
expense of the Trust Fund or the Trustee. At all times as may be required by the
Code, the Tax Administrator shall make reasonable efforts to ensure that
substantially all of the assets of each REMIC Pool will consist of "qualified
mortgages" as defined in Section 860G(a)(3) of the Code and "permitted
investments" as defined in Section 860G(a)(5) of the Code.

         (j) If any tax is imposed on any REMIC Pool, including "prohibited
transactions" taxes as defined in Section 860F(a)(2) of the Code, any tax on
"net income from foreclosure property" as defined in Section 860G(c) of the
Code, any taxes on contributions to any REMIC Pool after the Startup Day
pursuant to Section 860G(d) of the Code, and any other tax imposed by the Code
or any applicable provisions of State or Local Tax laws (other than any tax
permitted to be incurred by the Special Servicer pursuant to Section 3.17(a)),
such tax, together with all incidental costs and expenses (including penalties
and reasonable attorneys' fees), shall be charged to and paid by: (i) the Tax
Administrator, if such tax arises out of or results from a breach by the Tax
Administrator of any of its obligations under this Section 10.01; (ii) the
Special Servicer, if such tax arises out of or results from a breach by the
Special Servicer of any of its obligations under Article III or this Section
10.01; (iii) the Master Servicer, if such tax arises out of or results from a
breach by the Master Servicer of any of its obligations under Article III or
this Section 10.01; (iv) the Trustee, if such tax arises out of or results from
a breach by the Trustee of any of its obligations under Article IV, Article VIII
or this Section 10.01; (v) the Depositor, if such tax was imposed due to the
fact that any of the Lehman Trust Mortgage Loans did not, at the time of their
transfer to REMIC I, constitute a "qualified mortgage" as defined in Section
860G(a)(3) of the Code; or (vi) the Trust Fund, excluding the portion thereof
constituting the Grantor Trust, in all other instances. Any tax permitted to be
incurred by the Special Servicer pursuant to Section 3.17(a) shall be charged to
and paid by the Trust Fund (exclusive of the Grantor Trust Assets). Any such
amounts payable by the Trust Fund shall be paid by the Trustee upon the written
direction of the Tax Administrator out of amounts on deposit in the Collection
Account in reduction of the Available Distribution Amount pursuant to Section
3.05(b).

         (k) The Tax Administrator shall, for federal income tax purposes,
maintain books and records with respect to each REMIC Pool on a calendar year
and on an accrual basis.

         (l) Following the Startup Day, none of the Trustee, the Master Servicer
and the Special Servicer shall accept any contributions of assets to any REMIC
Pool unless it shall have received an Opinion of Counsel (at the expense of the
party seeking to cause such contribution and in no event at the expense of the
Trust Fund or the Trustee) to the effect that the inclusion of such assets in
such REMIC Pool will not cause: (i) such REMIC Pool to fail to qualify as a
REMIC at any time that any Certificates are outstanding; or (ii) the imposition
of any tax on such REMIC Pool under the REMIC Provisions or other applicable
provisions of federal, state and local law or ordinances.

         (m) None of the Trustee, the Master Servicer and the Special Servicer
shall consent to or, to the extent it is within the control of such Person,
permit: (i) the sale or disposition of any of the Trust Mortgage Loans (except
in connection with (A) the default or reasonably foreseeable material default of
a Trust Mortgage Loan, including, but not limited to, the sale or other
disposition of a Mortgaged Property acquired by deed in lieu of foreclosure, (B)
the bankruptcy of any REMIC Pool, (C) the termination of any REMIC Pool pursuant
to Article IX of this Agreement, or (D) a purchase of Trust Mortgage Loans
pursuant to or as contemplated by Article II or III of this Agreement); (ii) the
sale or

                                     -316-
<PAGE>

disposition of any investments in any Custodial Account or REO Account for gain;
or (iii) the acquisition of any assets for any REMIC Pool (other than a
Mortgaged Property acquired through foreclosure, deed in lieu of foreclosure or
otherwise in respect of a defaulted Trust Mortgage Loan and other than Permitted
Investments acquired in accordance with Section 3.06 in connection with the
investment of funds in a Custodial Account or an REO Account); in any event
unless it has received an Opinion of Counsel (at the expense of the party
seeking to cause such sale, disposition, or acquisition but in no event at the
expense of the Trust Fund or the Trustee) to the effect that such sale,
disposition, or acquisition will not cause: (x) any REMIC Pool to fail to
qualify as a REMIC at any time that any Certificates are outstanding; or (y) the
imposition of any tax on any REMIC Pool under the REMIC Provisions or other
applicable provisions of federal, state and local law or ordinances.

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

         SECTION 10.02. Grantor Trust Administration.

         (a) The Tax Administrator shall treat the Grantor Trust, for tax return
preparation purposes, as a grantor trust under the Code and, if necessary, under
applicable state law and will file appropriate federal or state Tax Returns for
each taxable year ending on or after the last day of the calendar year in which
the Certificates are issued.

         (b) The Tax Administrator shall pay out of its own funds any and all
routine tax administration expenses of the Trust Fund incurred with respect to
the Grantor Trust (but not including any professional fees or expenses related
to audits or any administrative or judicial proceedings with respect to the
Trust Fund that involve the IRS or state tax authorities which extraordinary
expenses shall be payable or reimbursable to the Tax Administrator from the
Grantor Trust Assets in the Trust Fund unless otherwise provided in Section
10.02(e) or 10.02(f)).

         (c) The Tax Administrator shall prepare, sign and file all of the Tax
Returns in respect of the Grantor Trust. The expenses of preparing and filing
such returns shall be borne by the Tax Administrator without any right of
reimbursement therefor. The Tax Administrator shall comply with such requirement
by filing Form 1041, indicating the name and address of the Trust and signed by
the Tax Administrator but otherwise left blank. There shall be appended to each
such form a schedule for each Certificateholder indicating such
Certificateholder's share of income and expenses of the Trust for the portion of
the preceding calendar year in which such Certificateholder possessed an
Ownership Interest in a Certificate. Such form shall be prepared in sufficient
detail to enable reporting on the cash or accrual method of accounting, as
applicable, and to report on such Certificateholder's fiscal year if other than
the calendar year. The other parties hereto shall provide on a timely basis to
the Tax Administrator or its designee such information with respect to the
Grantor Trust as is in its possession and reasonably requested by the Tax
Administrator to enable it to perform its obligations under this Section 10.02.
Without limiting the generality of the foregoing, the Depositor, within ten days
following the Tax Administrator's request therefor, shall provide in writing to
the Tax Administrator such information as is reasonably requested by the Tax
Administrator for tax purposes, and the Tax Administrator's duty to perform its
reporting and other tax compliance obligations under this Section

                                     -317-
<PAGE>

10.02 shall be subject to the condition that it receives from the Depositor such
information possessed by the Depositor that is necessary to permit the Tax
Administrator to perform such obligations.

         (d) The Tax Administrator shall perform on behalf of the Grantor Trust
all reporting and other tax compliance duties that are required in respect
thereof under the Code, the Grantor Trust Provisions or other compliance
guidance issued by the IRS or any state or local taxing authority, including the
furnishing to Certificateholders of the schedules described in Section 10.01(c).

         (e) The Tax Administrator shall perform its duties hereunder so as to
maintain the status of the Grantor Trust as a grantor trust under the Grantor
Trust Provisions (and the Trustee, the Master Servicer and the Special Servicer
shall assist the Tax Administrator to the extent reasonably requested by the Tax
Administrator and to the extent of information within the Trustee's, the Master
Servicer's or the Special Servicer's possession or control). None of the Tax
Administrator, Master Servicer, the Special Servicer or the Trustee shall
knowingly take (or cause the Grantor Trust to take) any action or fail to take
(or fail to cause to be taken) any action that, under the Grantor Trust
Provisions, if taken or not taken, as the case may be, could result in an
Adverse Grantor Trust Event, unless the Tax Administrator has obtained or
received an Opinion of Counsel (at the expense of the party requesting such
action or at the expense of the Trust Fund if the Tax Administrator seeks to
take such action or to refrain from taking any action for the benefit of the
Certificateholders) to the effect that the contemplated action will not result
in an Adverse Grantor Trust Event. None of the other parties hereto shall take
any action or fail to take any action (whether or not authorized hereunder) as
to which the Tax Administrator has advised it in writing that the Tax
Administrator has received or obtained an Opinion of Counsel to the effect that
an Adverse Grantor Trust Event could result from such action or failure to act.
In addition, prior to taking any action with respect to the Grantor Trust, or
causing the Trust Fund to take any action, that is not expressly permitted under
the terms of this Agreement, the Master Servicer and the Special Servicer shall
consult with the Tax Administrator or its designee, in writing, with respect to
whether such action could cause an Adverse Grantor Trust Event to occur. The Tax
Administrator may consult with counsel to make such written advice, and the cost
of same shall be borne by the party seeking to take the action not permitted by
this Agreement, but in no event at the cost or expense of the Trust Fund, the
Tax Administrator or the Trustee.

         (f) If any tax is imposed on the Grantor Trust, such tax, together with
all incidental costs and expenses (including penalties and reasonable attorneys'
fees), shall be charged to and paid by: (i) the Tax Administrator, if such tax
arises out of or results from a breach by the Tax Administrator of any of its
obligations under this Section 10.02; (ii) the Special Servicer, if such tax
arises out of or results from a breach by the Special Servicer of any of its
obligations under Article III or this Section 10.02; (iii) the Master Servicer,
if such tax arises out of or results from a breach by the Master Servicer of any
of its obligations under Article III or this Section 10.02; (iv) the Trustee, if
such tax arises out of or results from a breach by the Trustee of any of its
obligations under Article IV, Article VIII or this Section 10.02; or (v) the
portion of the Trust Fund constituting the Grantor Trust in all other instances.

                            MISCELLANEOUS PROVISIONS

         SECTION 11.01. Amendment.

         (a) This Agreement may be amended from time to time by the mutual
agreement of the parties hereto, without the consent of any of the
Certificateholders or any of the Non-Trust Mortgage Loan Noteholders, (i) to
cure any ambiguity, (ii) to correct, modify or supplement any provision herein
which may be inconsistent with any other provision herein or with the
description thereof in the Prospectus or the Prospectus Supplement, (iii) to add
any other provisions with respect to matters or questions arising hereunder
which shall not be inconsistent with the existing provisions hereof, (iv) to
relax or eliminate any requirement hereunder imposed by the REMIC Provisions if
the REMIC Provisions are amended or clarified such that any such requirement may
be relaxed or eliminated, (v) to relax or eliminate any requirement imposed by
the Securities Act or the rules promulgated thereunder if the Securities Act or
those rules are amended or clarified so as to allow for the relaxation or
elimination of that requirement; (vi) as evidenced by an Opinion of Counsel
delivered to the Master Servicer, the Special Servicer and the Trustee, either
(A) to comply with any requirements imposed by the Code or any successor or
amendatory statute or any temporary or final regulation, revenue ruling, revenue
procedure or other written official announcement or interpretation relating to
federal income tax laws or any such proposed action which, if made effective,
would apply retroactively to any of the REMIC Pools or the Grantor Trust at
least from the effective date of such amendment, or (B) to avoid the occurrence
of a prohibited transaction or to reduce the incidence of any tax that would
arise from any actions taken with respect to the operation of any REMIC Pool or
the Grantor Trust; (vii) as provided in Section 5.02(d)(iv), to modify, add to
or eliminate any of the provisions of Section 5.02(d)(i), (ii) or (iii); (viii)
to amend any provision of Section 8.15 as contemplated by Section 8.15(m); or
(ix) to otherwise modify or delete existing provisions of this Agreement;
provided that such amendment (other than any amendment for any of the specific
purposes described in clauses (i), (ii), (iv), (v), (vi), (vii) and (viii)
above) shall not adversely affect in any material respect the interests of any
Certificateholder or Non-Trust Mortgage Loan Noteholder, as evidenced by either
an Opinion of Counsel delivered to the Trustee and each other party hereto to
such effect or, in the case of a Class of Certificates to which a rating has
been assigned by one or more Rating Agencies, written confirmation from each
applicable Rating Agency to the effect that such amendment shall not result in
an Adverse Rating Event with respect to any Class of Certificates or any class
of GIC Office Pari Passu Non-Trust Mortgage Loan Securities rated by such Rating
Agency; and provided, further, that such amendment shall not significantly
change the activities of the Trust (insofar as such change would adversely
affect the status of the Trust as a "qualifying special-purpose entity" under
FASB 140).

         (b) This Agreement may also be amended from time to time by the
agreement of the parties hereto with the consent of the Holders of Certificates
entitled to at least 66-2/3% of the Voting Rights allocated to the affected
Classes for the purpose of adding any provisions to or changing in any manner or
eliminating any of the provisions of this Agreement or of modifying in any
manner the rights of the Holders of Certificates; provided, however, that no
such amendment shall (i) reduce in any manner the amount of, or delay the timing
of, payments received or advanced on Mortgage Loans which are required to be
distributed on any Certificate, without the consent of the Holder of such
Certificate, or which are required to be distributed to any Non-Trust Mortgage
Loan Noteholder, without the consent of

                                     -319-
<PAGE>

such Non-Trust Mortgage Loan Noteholder, (ii) adversely affect in any material
respect the interests of the Holders of any Class of Certificates or the
interests of any Non-Trust Mortgage Loan Noteholder in a manner other than as
described in the immediately preceding clause (i), without the consent of the
Holders of all Certificates of such Class or the consent of such Non-Trust
Mortgage Loan Noteholder, as the case may be, (iii) significantly change the
activities of the Trust (insofar as such change would adversely affect the
status of the Trust as a "qualifying special-purpose entity" under FASB 140)
without the consent of the Holders of Certificates entitled to 51% of all the
Voting Rights (without regard to Certificates held by the Depositor or any of
the Depositor's Affiliates and/or agents), (iv) modify the provisions of this
Section 11.01, without the consent of the Holders of all Certificates then
outstanding and the consent of all of the Non-Trust Mortgage Loan Noteholders,
(v) modify the provisions of Section 3.20 or the Servicing Standard, without the
consent of the Holders of all Regular Interest Certificates then outstanding and
the consent of all of the Non-Trust Mortgage Loan Noteholders, or (vi) modify
the specified percentage of Voting Rights which are required to be held by
Certificateholders to consent, approve or object to any particular action
pursuant to any provision of this Agreement without the consent of the Holders
of all Certificates then outstanding. Notwithstanding any other provision of
this Agreement, for purposes of the giving or withholding of consents pursuant
to this Section 11.01(b), Certificates registered in the name of any party
hereto or any Affiliate thereof shall be entitled to the same Voting Rights with
respect to matters described above as they would if any other Person held such
Certificates, so long as the subject amendment does not relate to increasing its
rights or reducing or limiting its obligations hereunder as a party to this
Agreement.

         (c) Notwithstanding any contrary provision of this Agreement, the
Trustee shall not consent to any amendment to this Agreement unless it shall
first have obtained or been furnished with an Opinion of Counsel (at the expense
of the party seeking such amendment) addressed to the Trustee and each other
party hereto, to the effect that (i) such amendment or the exercise of any power
granted to the Trustee, the Master Servicer or the Special Servicer in
accordance with such amendment will not result in the imposition of a tax on any
REMIC Pool pursuant to the REMIC Provisions, cause any REMIC Pool to fail to
qualify as a REMIC or cause the Grantor Trust to fail to qualify as a grantor
trust within the meaning of the Grantor Trust Provisions at any time that any
Certificates are outstanding and (ii) such amendment complies in all material
respects with the provisions of this Section 11.01.

         (d) Promptly after the execution of any such amendment, the Trustee
shall send a copy thereof to each Certificateholder and each Non-Trust Mortgage
Loan Noteholder.

         (e) It shall not be necessary for the consent of Certificateholders
under this Section 11.01 to approve the particular form of any proposed
amendment, but it shall be sufficient if such consent shall approve the
substance thereof. The manner of obtaining such consents and of evidencing the
authorization of the execution thereof by Certificateholders shall be subject to
such reasonable regulations as the Trustee may prescribe.

         (f) Each of the Master Servicer, the Special Servicer and the Trustee
may but shall not be obligated to enter into any amendment pursuant to this
section that affects its rights, duties and immunities under this Agreement or
otherwise.

         (g) The cost of any Opinion of Counsel to be delivered pursuant to
Section 11.01(a) or (c) shall be borne by the Person seeking the related
amendment, except that if the Master Servicer, the Special Servicer or the
Trustee requests any amendment of this Agreement that protects or is in

                                     -320-
<PAGE>

furtherance of the rights and interests of Certificateholders, the cost of any
Opinion of Counsel required in connection therewith pursuant to Section 11.01(a)
or (c) shall be payable out of the Pool Custodial Account, in the case of the
Master Servicer and the Special Servicer, pursuant to Section 3.05(a), or out of
the Collection Account, in the case of the Trustee, pursuant to Section 3.05(b).

         SECTION 11.02. Recordation of Agreement; Counterparts.

         (a) To the extent permitted by applicable law, this Agreement is
subject to recordation in all appropriate public offices for real property
records in all the counties or other comparable jurisdictions in which any or
all of the properties subject to the Mortgages are situated, and in any other
appropriate public recording office or elsewhere, such recordation to be
effected by the Master Servicer at the expense of the Trust Fund or, to the
extent that it benefits them, the Non-Trust Mortgage Loan Noteholders, but only
upon direction accompanied by an Opinion of Counsel (the cost of which may be
paid out of the Pool Custodial Account pursuant to Section 3.05(a) or, to the
extent that it benefits the Non-Trust Mortgage Loan Noteholders, out of the Loan
Combination Custodial Accounts pursuant to Section 3.05A and Section 3.05B), to
the effect that such recordation materially and beneficially affects the
interests of the Certificateholders and/or the Non-Trust Mortgage Loan
Noteholders; provided, however, that the Trustee shall have no obligation or
responsibility to determine whether any such recordation of this Agreement is
required.

         (b) For the purpose of facilitating the recordation of this Agreement
as herein provided and for other purposes, this Agreement may be executed
simultaneously in any number of counterparts, each of which counterparts shall
be deemed to be an original, and such counterparts shall constitute but one and
the same instrument.

         SECTION 11.03. Limitation on Rights of Certificateholders and the
                        Non-Trust Mortgage Loan Noteholders.

         (a) The death or incapacity of any Certificateholder or Non-Trust
Mortgage Loan Noteholder shall not operate to terminate this Agreement or the
Trust Fund, nor entitle such Certificateholder's or Non-Trust Mortgage Loan
Noteholder's legal representatives or heirs to claim an accounting or to take
any action or proceeding in any court for a partition or winding up of the Trust
Fund, nor otherwise affect the rights, obligations and liabilities of the
parties hereto or any of them.

         (b) No Certificateholder or Non-Trust Mortgage Loan Noteholder (except
as expressly provided for herein) shall have any right to vote or in any manner
otherwise control the operation and management of the Trust Fund, or the
obligations of the parties hereto, nor shall anything herein set forth, or
contained in the terms of the Certificates, be construed so as to constitute the
Certificateholders and/or the Non-Trust Mortgage Loan Noteholders from time to
time as partners or members of an association; nor shall any Certificateholder
or Non-Trust Mortgage Loan Noteholder be under any liability to any third party
by reason of any action taken by the parties to this Agreement pursuant to any
provision hereof.

         (c) No Certificateholder or Non-Trust Mortgage Loan Noteholder shall
have any right by virtue of any provision of this Agreement to institute any
suit, action or proceeding in equity or at law upon or under or with respect to
this Agreement or any Mortgage Loan, unless, with respect to any suit, action or
proceeding upon or under or with respect to this Agreement, such Person
previously shall have given to the Trustee a written notice of default
hereunder, and of the continuance thereof, as

                                     -321-
<PAGE>

hereinbefore provided, and unless also (except in the case of a default by the
Trustee) the Holders of Certificates entitled to at least 25% of the Voting
Rights or a Non-Trust Mortgage Loan Noteholder shall have made written request
upon the Trustee to institute such action, suit or proceeding in its own name as
Trustee hereunder and shall have offered to the Trustee such reasonable
indemnity as it may require against the costs, expenses and liabilities to be
incurred therein or thereby, and the Trustee, for 60 days after its receipt of
such notice, request and offer of indemnity, shall have neglected or refused to
institute any such action, suit or proceeding. It is understood and intended,
and expressly covenanted by each Certificateholder with every other
Certificateholder and the Trustee, that no one or more Holders of Certificates
shall have any right in any manner whatsoever by virtue of any provision of this
Agreement to affect, disturb or prejudice the rights of the Holders of any other
of such Certificates, or to obtain or seek to obtain priority over or preference
to any other such Holder, which priority or preference is not otherwise provided
for herein, or to enforce any right under this Agreement, except in the manner
herein provided and for the equal, ratable and common benefit of all
Certificateholders. For the protection and enforcement of the provisions of this
section, each and every Certificateholder and the Trustee shall be entitled to
such relief as can be given either at law or in equity.

         SECTION 11.04. Governing Law; Consent to Jurisdiction.

         This Agreement will be governed by and construed in accordance with the

         SECTION 11.06. Severability of Provisions.

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

         SECTION 11.07. Grant of a Security Interest.

         The Depositor and the Trustee agree that it is their intent that the
conveyance of the Depositor's right, title and interest in and to the Trust
Mortgage Loans pursuant to this Agreement shall constitute a sale and not a
pledge of security for a loan. If such conveyance is deemed to be a pledge of
security for a loan, however, the Depositor and the Trustee agree that it is
their intent that the rights and obligations of the parties to such loan shall
be established pursuant to the terms of this Agreement. The Depositor and the
Trustee also intend and agree that, in such event, (i) in order to secure
performance of the Depositor's obligations hereunder and payment of the
Certificates, the Depositor shall be deemed to have granted, and does hereby
grant, to the Trustee (in such capacity) a first priority security interest in
the Depositor's entire right, title and interest in and to the assets
constituting the Trust Fund, including the Trust Mortgage Loans, all principal,
interest and other amounts received or receivable with respect to the Trust
Mortgage Loans after the Closing Date (other than principal and interest
payments due and payable prior to the Cut-off Date, and other than any Principal
Prepayments received on or prior to the Cut-off Date), all amounts (other than
those allocable to the Non-Trust Mortgage Loans and/or any successor REO
Mortgage Loans with respect thereto) held from time to time in the Custodial
Accounts, the Collection Account, the Interest Reserve Account, the Excess
Liquidation Proceeds Account and, if established, the REO Account(s) and the
Defeasance Deposit Account and any and all reinvestment earnings on such
amounts, and all of the Depositor's right, title and interest in and to the
proceeds of any title, hazard or other Insurance Policies related to the Trust
Mortgage Loans, and (ii) this Agreement shall constitute a security agreement
under applicable law. The Depositor shall file or cause to be filed, as a
precautionary filing, a Form UCC-1, which shall include a Schedule I
substantially in the form attached as Exhibit J hereto in the State of Delaware
promptly following the initial issuance of the Certificates, and the Trustee
shall prepare, execute and file at each such office, with the consent of the
Depositor hereby given, continuation statements with respect thereto, in each
case within six months prior to the fifth anniversary

                                     -323-
<PAGE>

of the immediately preceding filing. The Depositor shall cooperate in a
reasonable manner with the Trustee and the Master Servicer in preparing and
filing such continuation statements. This Section 11.07 shall constitute notice
to the Trustee pursuant to any of the requirements of the UCC.

         SECTION 11.08. Streit Act.

         Any provisions required to be contained in this Agreement by Section
126 of Article 4-A of the New York Real Property Law are hereby incorporated
herein, and such provisions shall be in addition to those conferred or imposed
by this Agreement; provided, however, that to the extent that such Section 126
shall not have any effect, and if said Section 126 should at any time be
repealed or cease to apply to this Agreement or be construed by judicial
decision to be inapplicable, said Section 126 shall cease to have any further
effect upon the provisions of this Agreement. In case of a conflict between the
provisions of this Agreement and any mandatory provisions of Article 4-A of the
New York Real Property Law, such mandatory provisions of said Article 4-A shall
prevail, provided that if said Article 4-A shall not apply to this Agreement,
should at any time be repealed, or cease to apply to this Agreement or be
construed by judicial decision to be inapplicable, such mandatory provisions of
such Article 4-A shall cease to have any further effect upon the provisions of
this Agreement.

         SECTION 11.09. Successors and Assigns; Beneficiaries.

         The provisions of this Agreement shall be binding upon and inure to the
benefit of the respective successors and assigns of the parties hereto, and all
such provisions shall inure to the benefit of the Certificateholders. Each
Underwriter shall be a third party beneficiary to this Agreement solely with
respect to its right to receive the reports, statements and other information to
which it is entitled hereunder, to preserve such Underwriter's rights under
Sub-Servicing Agreements as contemplated by Section 3.22(d) and, in the case of
Lehman Brothers, to terminate the Trust Fund pursuant to Section 9.01. Each of
the Sub-Servicers that is a party to a Sub-Servicing Agreement in effect on the
Closing Date (or being negotiated as of the Closing Date and in effect within 90
days thereafter) shall be a third party beneficiary to the obligations of a
successor Master Servicer under Section 3.22, provided that the sole remedy for
any claim by a Sub-Servicer as a third party beneficiary pursuant to this
Section 11.09 shall be against a successor Master Servicer solely in its
corporate capacity and no Sub-Servicer shall have any rights or claims against
the Trust Fund or any party hereto (other than a successor Master Servicer in
its corporate capacity as set forth in this Section 11.09) as a result of any
rights conferred on such Sub-Servicer as a third party beneficiary pursuant to
this Section 11.09. The Non-Trust Mortgage Loan Noteholders and any designees
thereof acting on behalf of or exercising the rights of the Non-Trust Mortgage
Loan Noteholders shall be third-party beneficiaries to this Agreement with
respect to their rights as specifically provided for herein. This Agreement may
not be amended in any manner that would adversely affect the rights of any such
third party beneficiary without its consent. This Agreement may not be amended
in any manner that would materially and adversely affect the rights of any such
third-party beneficiary without its consent. No other Person, including any
Mortgagor, shall be entitled to any benefit or equitable right, remedy or claim
under this Agreement.

         SECTION 11.10. Article and Section Headings.

         The article and section headings herein are for convenience of
reference only, and shall not limit or otherwise affect the meaning hereof.

         (g) The Master Servicer shall give Moody's at least 15 days notice
prior to any reimbursement to it of Nonrecoverable Advances from amounts in the
Pool Custodial Account allocable to interest on the Trust Mortgage Loans unless
(1) the Master Servicer determines in its sole discretion that waiting 15 days
after such a notice could jeopardize the Master Servicer's ability to recover
Nonrecoverable Advances, (2) changed circumstances or new or different
information becomes known to the Master Servicer that could affect or cause a
determination of whether any Advance is a Nonrecoverable Advance, whether to
defer reimbursement of a Nonrecoverable Advance or the determination in clause

as reasonably practicable in such circumstances. The Master Servicer shall have
no liability for any loss, liability or expense resulting from any notice
provided to Moody's contemplated by the immediately preceding sentence.

         (h) Each of the Trustee, the Master Servicer and the Special Servicer
shall provide to each Rating Agency such other information with respect to the
Mortgage Loans and the Certificates, to the extent such party possesses such
information, as such Rating Agency shall reasonably request.

                                       interest in approximately 3.75 acres of real property and a fee simple interest
                                       in approximately .4 acres of real property. Upon expiration or termination of the
                                       related ground lease due to borrower default, the ground lessor is entitled to
                                       purchase the portion of the related property owned in fee by the related borrower
                                       free of liens for the "Fair Market Value" of such property (determined in
                                       accordance with the ground lease and the document entitled Easement and
                                       Declaration of Protective Covenants between ground lessor and the borrower). In
                                       the event the purchase option becomes effective due to borrower default under the
                                       ground lease, the ground lessor may elect to pay the purchase price at the
                                       purchase closing, or to pay 10% of the price at closing and deliver to the
                                       related borrower a note for the remainder of the purchase price. Such note shall
                                       contain terms and conditions further described in the ground lease, bear an
                                       interest rate equal to the lesser of the prime interest rate or 10% per annum,
                                       and be secured by a deed of trust against the subject property. In the event the
                                       ground lease is terminated due to a borrower default thereunder, the granting of
                                       a new lease to mortgagee or mortgagee's nominee, pursuant to the terms of the
                                       ground lease and ground lease estoppel, shall not be considered a termination of
                                       the ground lease triggering this purchase option.

                                       Arbor Plaza. There is a purchase option pertaining to approximately 12,180 square

                                       center. The property subject to the purchase option comprises approximately 3.5%
                                       of the total mortgaged property, and is presently used for parking. The Option
                                       Property is subject to a non-exclusive easement for ingress, egress and parking
                                       in favor of the Option Holder. The purchase option may be exercised in the event
                                       that the parking stalls located on Option Property are unavailable for use by the
                                       owner, employees or customers of the Option Holder's property, to an extent that
                                       the Option Holder believes in good faith is adversely impacting the business
                                       conducted on the Option Holder's property. The Option Property shall be conveyed
                                       free of liens. No purchase price is specified; however, in connection with the
                                       purchase the Option Holder is obligated to reimburse the borrower for any Special
                                       Improvement District Number 88 Arbor Plaza P.U.D. payments made subsequent to
                                       February 5, 1990, together with interest thereon at the per annum rate of .6887%.
                                       The purchase option expires at the earlier of June 14, 2040, or 21 years after
                                       the death of the last of Option Holder or Option Holder's children to die. See
                                       also the entry with respect to this loan on Schedule (xxx) "Property Release".

                                       GIC Office Portfolio. The related mortgages secure both the GIC Office Portfolio

                                       ("MGM") entered into a lease for space in the MGM Tower ("MGM Lease"), which

                                       property and restricts the right of the related borrower to change the name of
                                       the related mortgaged property.

                                             The MGM Lease grants to MGM and its "affiliates" (as such term is defined in

                                       related mortgaged property. At any time during the term of the MGM Lease that the
                                       landlord shall elect to market the same for sale to third parties and MGM is then
                                       leasing and occupying over 50% of the rentable square footage of the MGM Tower.

                                       are to agree upon the allocation of any proceeds, failing which the allocation shall
                                       be determined by appraisers in accordance with the terms of the ground lease.  In the
                                       event of a taking for a public or quasi-public use, the ground lessor is entitled to

                                       provides that after the physical loss to the applicable mortgaged property has
                                       been repaired, the continued loss of income will be insured until such income
                                       either returns to the same level it was at prior to the loss, or the expiration
                                       of 180 days from the date that the applicable mortgaged property is repaired,
                                       whichever first occurs.

                                             The related loan documents require earthquake insurance in an amount equal to

                                       nonconforming uses. The related loan documents require law and ordinance
                                       insurance if the mortgaged property is a legal non-conforming use, but the
                                       related originator did not obtain such insurance at origination. As of the
                                       Cut-Off Date, the related originator has requested each related borrower to
                                       obtain law and ordinance insurance covering the related mortgaged property.

                                       entity rather than an individual is the environmental indemnitor.

                                       Bark River. Failure to comply with the related environmental indemnity agreement
                                       is not a recourse carve-out event for the environmental indemnitor.

                                       Centre at River Oaks. The Phase I environmental assessment reported that a prior
                                       assessment identified solvents in shallow groundwater and soil believed to be
                                       associated with an off-site source.

                                       Corporation, are performing initial investigations under the supervision of the
                                       state regulatory agency to determine the extent and scope of the contamination.

                                       Fullerton University. Active remediation is ongoing due to impact on the property
                                       from an historic gasoline station. Tesoro Corporation has been identified as the

                                       representations are to the borrower's current actual knowledge, after or in
                                       connection with due inquiry of the kind a sophisticated and prudent prospective
                                       purchaser of a property similar to the mortgaged property would perform in the
                                       course of performing its due diligence and as consistent with other projects that
                                       the borrower or its affiliates have purchased.

                                             The environmental indemnitor is not liable for the related borrower's failure
                                       to comply with the environmental indemnity agreement, but the environmental
                                       indemnitor executed a separate environmental indemnity agreement. The
                                       environmental indemnitor is not liable for matters arising as a result of the
                                       actions of any indemnified party or for hazardous materials introduced to the
                                       mortgaged property by anyone other than the environmental indemnitor following
                                       termination or satisfaction of the mortgage, foreclosure of the mortgage or the

                                       individual indemnitors under the environmental indemnity agreement shall
                                       terminate on the 5th anniversary of (A) payment in full of the Note or (B) the

                                       Lufkin Mall; Green River. Failure to comply with the related environmental
                                       indemnity agreement is not a recourse carve-out event for the borrower or the
                                       environmental indemnitor.

                                       MGM Tower. Diminution in value is expressly excluded from indemnified losses.

                                       The Fountains. The environmental indemnitor is not liable for the related

                                       indemnitors under the environmental indemnity agreement shall terminate on the

                                       agreement, but the environmental indemnitor has signed the environmental

                                       (B) The assignment to the Trustee upon foreclosure may be accomplished without
                                       the consent of the ground lessor so long as the Trustee is the purchaser at the
                                       foreclosure sale or Lender's the nominee for an assignment-in-lieu of
                                       foreclosure. Otherwise the transfer to the Trustee is, as with other assignments,
                                       subject to the ground lessor's approval which shall not be unreasonably withheld.

                                       (J) With respect to insurance proceeds, Lender or a successor to Lender's

                                       due to a default of the borrower or rejection of the ground lease by the borrower
                                       in a bankruptcy proceeding, provided that Lender pays all amounts then owed to

                                       (J) Lender may serve as trustee, but if Lender wishes to appoint a separate
                                       trustee (other than a successor to Lender's interest in the mortgage) with
                                       respect to insurance proceeds in excess of $250,000, such trustee must be one of

THEIR RESPECTIVE AFFILIATES. NEITHER THIS CERTIFICATE NOR THE MORTGAGE LOANS ARE

SOLELY FOR U.S. FEDERAL INCOME TAX PURPOSES, THIS CERTIFICATE IS A "REGULAR
INTEREST" IN A "REAL ESTATE MORTGAGE INVESTMENT CONDUIT" (A "REMIC") AS THOSE
TERMS ARE DEFINED, RESPECTIVELY, IN SECTIONS 860G AND 860D OF THE CODE.

THE OUTSTANDING CERTIFICATE PRINCIPAL BALANCE HEREOF AT ANY TIME MAY BE LESS
THAN THE AMOUNT SHOWN ABOVE.

         This certifies that Cede & Co. is the registered owner of the
Percentage Interest evidenced by this Certificate (obtained by dividing the
principal balance of this Certificate (its "Certificate Principal Balance") as
of the Closing Date by the aggregate principal balance of all the Certificates
of the same Class as this Certificate (their "Class Principal Balance") as of
the Closing Date) in that certain beneficial ownership interest in the Trust
evidenced by all the Certificates of the same Class as this Certificate. The
Trust was created and the Certificates were issued pursuant to a Pooling and
Servicing Agreement, dated as specified above (the "Agreement"), between
Structured Asset Securities Corporation II, as depositor (the "Depositor", which
term includes any successor entity under the Agreement), Wachovia Bank, National
Association, as master servicer (the "Master Servicer", which term includes any
successor entity under the Agreement), Lennar Partners, Inc., as special
servicer (the "Special Servicer", which term includes any successor entity under
the Agreement), LaSalle Bank National Association, as trustee (the "Trustee",
which term includes any successor entity under the Agreement), and ABN AMRO Bank
N.V., as fiscal agent (the "Fiscal Agent", which term includes any successor
entity under the Agreement), a summary of certain of the pertinent provisions of
which is set forth hereafter. To the extent not defined herein, the capitalized
terms used herein have the respective meanings assigned in the Agreement. This
Certificate is issued under and is subject to the terms, provisions and
conditions of the Agreement, to which Agreement the Holder of this Certificate
by virtue of the acceptance hereof assents and by which such Holder is bound. In
the event of any conflict between any provision of this Certificate and any
provision of the Agreement, such provision of this Certificate shall be
superseded to the extent of such inconsistency.

         Pursuant to the terms of the Agreement, distributions will be made on
the 4th Business Day following the 11th calendar day of each month (or, if such
11th calendar day is not a Business Day, then the 5th Business Day following
such 11th calendar day) (each, a "Distribution Date"), commencing on the first
Distribution Date specified above, to the Person in whose name this Certificate
is registered at the close of business on the last Business Day of the month
immediately preceding the month of such distribution (the "Record Date"), in an

Certificate will be made by the Trustee by wire transfer in immediately
available funds to the account of the Person entitled thereto at a bank or other
entity having appropriate facilities therefor, if

                                     A-1-3

mailed to the address of such Certificateholder appearing in the Certificate
Register. Notwithstanding the above, the final distribution in respect of this
Certificate (determined without regard to any possible future reimbursement of
any Realized Loss or Additional Trust Fund Expense previously allocated to this
Certificate) will be made after due notice by the Trustee of the pendency of
such distribution and only upon presentation and surrender of this Certificate
at the offices of the Certificate Registrar appointed as provided in the
Agreement or such other location as may be specified in such notice. Also
notwithstanding the foregoing, any distribution that may be made with respect to
this Certificate in reimbursement of any Realized Loss or Additional Trust Fund
Expense previously allocated to this Certificate, which reimbursement is to
occur after the date on which this Certificate is surrendered as contemplated by
the preceding sentence, will be made by check mailed to the address of the
Holder that surrenders this Certificate as such address last appeared in the
Certificate Register or to any such other address of which the Trustee is
subsequently notified in writing.

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

Agreement, withdrawals from the Custodial Accounts, the Collection Account and,
if established, the REO Accounts may be made from time to time for purposes
other than, and, in certain cases, prior to, distributions to
Certificateholders, such purposes including the reimbursement of advances made,
or certain expenses incurred, with respect to the Mortgage Loans and the payment
of interest on such advances and expenses.

         The Certificates are issuable in fully registered form only without
coupons in minimum denominations specified in the Agreement. As provided in the
Agreement and subject to certain limitations therein set forth, 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.

         As provided in the Agreement and subject to certain limitations therein
set forth, the transfer of this Certificate is registrable in the Certificate
Register upon surrender of this Certificate for registration of transfer at the
offices of the Certificate Registrar, duly endorsed by, or accompanied by a

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

         [FOR BOOK ENTRY CERTIFICATES:] Notwithstanding the foregoing, for so
long as this Certificate is registered in the name of Cede & Co. or in such
other name as is requested by an authorized representative of DTC, transfers of
interests in this Certificate shall be made through the book-entry facilities of
DTC.

         The Holder of this Certificate, by its acceptance hereof, shall be
deemed to have agreed to keep confidential any information it obtains from the
Trustee (except that such Holder may provide any such information obtained by it
to any other Person that holds or is contemplating the purchase of this
Certificate or an interest herein, provided that such other Person confirms in
writing such ownership interest or prospective ownership interest and agrees to
keep such information confidential). Notwithstanding the foregoing, each offeree
and/or holder of this Certificate (and each employee, representative, or other
agent of such offeree or holder) may disclose to any and all persons, without
limitation of any kind, the tax treatment and tax structure of the transactions
(as defined in section 1.6011-4 of the Treasury Department regulations)
associated herewith and all materials of any kind (including opinions or other
tax analyses) that are provided to the taxpayer relating to such tax treatment
and tax structure.

         Prior to due presentment of this Certificate for registration of
transfer, the Depositor, the Master Servicer, the Special Servicer, the Trustee,
the Fiscal Agent, the Certificate Registrar and any agents of any of them may
treat the Person in whose name this Certificate is registered as the owner
hereof for all purposes, and none of the Depositor, the Master Servicer, the
Special Servicer, the Trustee, the Fiscal Agent, the Certificate Registrar or
any such agent shall be affected by notice to the contrary.

         Subject to certain terms and conditions set forth in the Agreement, the
Trust and the obligations created by the Agreement shall terminate upon
distribution (or provision for distribution) to the Certificateholders of all
amounts held by or on behalf of the Trustee and required to be distributed to
them pursuant to the Agreement following the earlier of (i) the final payment
(or any advance with respect thereto) on or other liquidation of the last
Mortgage Loan or REO Property remaining in the Trust, and (ii) the purchase by
the Depositor, Lehman Brothers Inc., the Master Servicer, the Special Servicer
or any Controlling Class Certificateholder at a price determined as provided in
the Agreement of all Mortgage Loans and any REO Properties remaining in the
Trust. The Agreement permits, but

                                     A-1-5
<PAGE>

does not require, the Depositor, Lehman Brothers Inc., the Master Servicer, the
Special Servicer or any Controlling Class Certificateholder to purchase from the
Trust all Mortgage Loans and any REO Properties remaining therein. The exercise
of such right will effect early retirement of the Certificates; however, such
right to purchase is subject to the aggregate Stated Principal Balance of the
Mortgage Pool at the time of purchase being less than approximately 1.0% of the
aggregate Certificate Principal Balance of all the Principal Balance
Certificates as of the Closing Date. In addition, following the date on which
the total principal balance of the Class A-1, A-2, A-3, A-4, B, C, D, E, F and G
Certificates is reduced to zero, any single Holder or group of Holders of all of
the remaining Certificates may, with the consent of the Master Servicer and
subject to such other conditions as may be set forth in the Agreement, exchange
those Certificates for all Mortgage Loans and REO Properties remaining in the
Trust Fund at the time of the exchange.

         The Agreement permits, with certain exceptions therein provided, the
amendment thereof, and the modification of the rights and obligations of the
Depositor, the Master Servicer, the Special Servicer, the Trustee and the Fiscal
Agent thereunder and the rights of the Certificateholders thereunder, at any
time by the Depositor, the Master Servicer, the Special Servicer, the Trustee
and the Fiscal Agent with the consent of the Holders of Certificates entitled to
at least 66-2/3% of the Voting Rights allocated to the affected Classes. Any
such consent by the Holder of this Certificate shall be conclusive and binding
on such Holder and upon all future Holders of this Certificate and of any
Certificate issued upon the transfer hereof or in exchange herefor or in lieu
hereof whether or not notation of such consent is made upon this Certificate.
The Agreement also permits the amendment thereof, in certain circumstances,
including any amendment necessary to maintain the status of any REMIC Pool as a
REMIC, without the consent of the Holders of any of the Certificates.

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

         The registered Holder hereof, by its acceptance hereof, agrees that it
will look solely to the Trust (to the extent of its rights therein) for
distributions hereunder.

         This Certificate shall be construed in accordance with the internal
laws of the State of New York applicable to agreements made and to be performed
in said State, without applying any conflicts of law principles of such state
(other than the provisions of Section 5-1401 of the New York General Obligations
Law), and the obligations, rights and remedies of the Holder hereof shall be
determined in accordance with such laws.

hereof is to be made without registration under the Securities Act (other than

this Certificate by the Depositor, Lehman Brothers Inc. or any of their
respective Affiliates or, if this Certificate is a Global Certificate, a

Certificate Owner in accordance with Section 5.03 of the Agreement), then the
Certificate Registrar shall refuse to register such Transfer unless it receives
(and, upon receipt, may conclusively rely upon) either: (i) a certificate from
the Certificateholder desiring to effect such Transfer substantially in the form
attached as Exhibit F-1 to the Agreement and a certificate from such
Certificateholder's prospective Transferee substantially in the form attached

is based. If any Transferee of this Certificate does not, in connection with the
subject Transfer, deliver to the Certificate Registrar one of the certifications
described in clause (i) of the preceding sentence or the Opinion of Counsel

respect to the subject Transfer, true and correct.

         If this Certificate constitutes a Rule 144A Global Certificate and a
Transfer of any interest herein is to be made without registration under the
Securities Act (other than in connection with the initial issuance of the
Certificates or a Transfer of any interest herein by the Depositor, Lehman
Brothers Inc. or any of their respective Affiliates), then the Certificate Owner
desiring to effect such Transfer shall be required to obtain either (i) a
certificate from such Certificate Owner's prospective Transferee substantially
in the form attached as Exhibit F-2C to the Agreement, or (ii) an Opinion of
Counsel to the effect that such Transferee is a Qualified Institutional Buyer
and such Transfer may be made without registration under the Securities Act.

constitutes a Rule 144A Global Certificate and any Transferee of an interest
herein does not, in connection with the subject Transfer, deliver to the
Transferor the Opinion of Counsel or the certification described in the second
preceding sentence, then such Transferee shall be deemed to have represented and
warranted that all the certifications set forth in Exhibit F-2C attached to the
Agreement are, with respect to the subject Transfer, true and correct.

         Notwithstanding the preceding paragraph, any interest in a Rule 144A
Global Certificate for a Class of Book-Entry Non-Registered Certificates may be
transferred (without delivery of any certificate or Opinion of Counsel described
in clauses (i) and (ii) of the first sentence of the preceding paragraph) by the
Depositor or any Affiliate of the Depositor to any Person who takes delivery in
the form of a beneficial interest in the Regulation S Global Certificate for
such Class of Certificates upon delivery to the Certificate Registrar of (x) a
certificate to the effect that the Certificate Owner desiring to effect such
Transfer is the Depositor or an Affiliate of the Depositor and (y) such written
orders and instructions as are required under the applicable procedures of the
Depository, Clearstream and Euroclear to direct the Trustee to debit the account
of a Depository Participant by a denomination of interests in such Rule 144A
Global Certificate, and credit the account of a Depository Participant by a
denomination of interests in such Regulation S Global Certificate, that is equal
to the denomination of beneficial interests in the subject Class of Certificates
to be transferred. Upon delivery to the Certificate Registrar of such
certification and such orders and instructions, the Trustee, subject to and in
accordance with the applicable procedures of the Depository, shall reduce the
denomination of the Rule 144A Global Certificate in respect of the subject Class
of Certificates and increase the denomination of the Regulation S Global
Certificate for such Class, by the denomination of the beneficial interest in
such Class specified in such orders and instructions.

         Also notwithstanding the second preceding paragraph, any interest in a
Rule 144A Global Certificate with respect to any Class of Book-Entry
Non-Registered Certificates may be transferred by any Certificate Owner holding
such interest to any Institutional Accredited Investor (other than a Qualified
Institutional Buyer) that takes delivery in the form of a Definitive Certificate
of the same Class as such Rule 144A Global Certificate upon delivery to the
Certificate Registrar and the Trustee of (i) such certifications and/or opinions
as are contemplated by the third preceding paragraph, (ii) a certification from
such Certificate Owner to the effect that it is the lawful owner of the
beneficial interest being transferred and (iii) such written orders and
instructions as are required under the applicable procedures of the Depository
to direct the Trustee to debit the account of a Depository Participant by the
denomination of the transferred interests in such Rule 144A Global Certificate.
Upon delivery to the Certificate Registrar of such certifications and/or
opinions and such orders and instructions, the Trustee, subject to and in
accordance with the applicable procedures of the Depository, shall reduce the
denomination of the subject Rule 144A Global Certificate by the denomination of
the transferred interests in such Rule 144A Global Certificate, and shall cause
a Definitive Certificate of the same Class as such Rule 144A Global Certificate,
and in a denomination equal to the reduction in the denomination of such Rule
144A Global Certificate, to be executed, authenticated and delivered in
accordance with the Agreement to the applicable Transferee.

         Except as provided in the next paragraph no beneficial interest in a
Regulation S Global Certificate for any Class of Book-Entry Non-Registered
Certificates shall be transferred to any Person who takes delivery other than in
the form of a beneficial interest in such Regulation S Global Certificate.

such Transfer shall be required to obtain from such Certificate Owner's
prospective Transferee a written certification substantially in the form set

United States Securities Person. On or prior to the Release Date, beneficial

Non-Registered Certificates may be held only through Euroclear or Clearstream.

         Notwithstanding the preceding paragraph, any interest in a Regulation S
Global Certificate for a Class of Book-Entry Non-Registered Certificates may be

takes delivery in the form of a beneficial interest in the Rule 144A Global
Certificate for such Class of Certificates upon delivery to the Certificate
Registrar of (x) a certificate to the effect that the Certificate Owner desiring
to effect such Transfer is the Depositor or an Affiliate of the Depositor and
(y) such written orders and instructions as are required under the applicable
procedures of the Depository, Clearstream and Euroclear to direct the Trustee to
debit the account of a Depository Participant by a denomination of interests in
such Regulation S Global Certificate, and credit the account of a Depository
Participant by a denomination of interests in such Rule 144A Global Certificate,
that is equal to the denomination of beneficial interests in the subject Class
of Certificates to be transferred. Upon delivery to the Certificate Registrar of
such certification and such orders and instructions, the Trustee, subject to and
in accordance with the applicable procedures of the Depository, shall reduce the
denomination of the Regulation S Global Certificate in respect of the subject
Class of Certificates and increase the denomination of the Rule 144A Global
Certificate for such Class, by the denomination of the beneficial interest in
such Class specified in such orders and instructions.

         None of the Depositor, the Trustee or the Certificate Registrar is
obligated to register or qualify the Class of Certificates to which this
Certificate belongs, under the Securities Act or any other securities law or to
take any action not otherwise required under the Agreement to permit the
Transfer of this Certificate or any interest herein without such registration or

this Certificate constitutes a Definitive Certificate) or the Transferor (if
this Certificate constitutes a Global Certificate) a certification and/or
Opinion of Counsel as required by the preceding sentence, then such Transferee
shall be deemed to have represented and warranted that (a) such Transferee is
not an Ineligible Purchaser and (b) either: (i) such Transferee is not a Plan
and is not directly or indirectly purchasing this Certificate or any interest
herein on behalf of, as named fiduciary of, as trustee of, or with assets of a

Certificate or such interest herein by such Transferee is exempt from the
prohibited transaction provisions of Sections 406(a) and (b) and 407 of ERISA
and the excise taxes imposed on such prohibited transactions by Sections 4975(a)
and (b) of the Code. Any acquisition or holding of a Certificate by an
Ineligible Purchaser shall be void ab initio and of no force and effect.

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

         [FOR BOOK ENTRY CERTIFICATES:] Notwithstanding the foregoing, for so
long as this Certificate is registered in the name of Cede & Co. or in such
other name as is requested by an authorized representative of DTC, transfers of
interests in this Certificate shall be made through the book-entry facilities of
DTC.

         The Holder of this Certificate, by its acceptance hereof, shall be
deemed to have agreed to keep confidential any information it obtains from the
Trustee (except that such Holder may provide any such information obtained by it
to any other Person that holds or is contemplating the purchase of this
Certificate or an interest herein, provided that such other Person confirms in
writing such ownership interest or prospective ownership interest and agrees to
keep such information confidential). Notwithstanding the foregoing, each offeree
and/or holder of this Certificate (and each employee, representative, or other
agent of such offeree or holder) may disclose to any and all persons, without
limitation of any kind, the tax treatment and tax structure of the transactions
(as defined in section 1.6011-4 of the Treasury Department regulations)
associated herewith and all materials of any kind (including opinions or other
tax analyses) that are provided to the taxpayer relating to such tax treatment
and tax structure.

         Prior to due presentment of this Certificate for registration of
transfer, the Depositor, the Master Servicer, the Special Servicer, the Trustee,
the Fiscal Agent, the Certificate Registrar and any agents of any of them may
treat the Person in whose name this Certificate is registered as the owner
hereof for all purposes, and none of the Depositor, the Master Servicer, the
Special Servicer, the Trustee, the Fiscal Agent, the Certificate Registrar or
any such agent shall be affected by notice to the contrary.

         Subject to certain terms and conditions set forth in the Agreement, the
Trust and the obligations created by the Agreement shall terminate upon
distribution (or provision for distribution) to the Certificateholders of all
amounts held by or on behalf of the Trustee and required to be distributed to
them pursuant to the Agreement following the earlier of (i) the final payment
(or any advance with respect thereto) on or other liquidation of the last
Mortgage Loan or REO Property remaining in the Trust, and (ii) the purchase by
the Depositor, Lehman Brothers Inc., the Master Servicer, the Special Servicer
or any Controlling Class Certificateholder at a price determined as provided in
the Agreement of all Mortgage Loans and any REO Properties remaining in the
Trust. The Agreement permits, but does not require, the Depositor, Lehman
Brothers Inc., the Master Servicer, the Special Servicer or any Controlling
Class Certificateholder to purchase from the Trust all Mortgage Loans and any
REO Properties remaining therein. The exercise of such right will effect early
retirement of the Certificates; however, such right to purchase is subject to
the aggregate Stated Principal Balance of the Mortgage Pool at the time of
purchase being less than approximately 1.0% of the aggregate Certificate
Principal Balance of all the Principal Balance Certificates as of the Closing
Date. In addition, following the date

                                     A-2-9
<PAGE>

on which the total principal balance of the Class A-1, A-2, A-3, A-4, B, C, D,
E, F and G Certificates is reduced to zero, any single Holder or group of
Holders of all of the remaining Certificates may, with the consent of the Master
Servicer and subject to such other conditions as may be set forth in the
Agreement, exchange those Certificates for all Mortgage Loans and REO Properties
remaining in the Trust Fund at the time of the exchange.

         The Agreement permits, with certain exceptions therein provided, the
amendment thereof, and the modification of the rights and obligations of the
Depositor, the Master Servicer, the Special Servicer, the Trustee and the Fiscal
Agent thereunder and the rights of the Certificateholders thereunder, at any
time by the Depositor, the Master Servicer, the Special Servicer, the Trustee
and the Fiscal Agent with the consent of the Holders of Certificates entitled to
at least 66-2/3% of the Voting Rights allocated to the affected Classes. Any
such consent by the Holder of this Certificate shall be conclusive and binding
on such Holder and upon all future Holders of this Certificate and of any
Certificate issued upon the transfer hereof or in exchange herefor or in lieu
hereof whether or not notation of such consent is made upon this Certificate.
The Agreement also permits the amendment thereof, in certain circumstances,
including any amendment necessary to maintain the status of any REMIC Pool as a
REMIC, without the consent of the Holders of any of the Certificates.

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

         The registered Holder hereof, by its acceptance hereof, agrees that it
will look solely to the Trust (to the extent of its rights therein) for
distributions hereunder.

         This Certificate shall be construed in accordance with the internal
laws of the State of New York applicable to agreements made and to be performed
in said State, without applying any conflicts of law principles of such state
(other than the provisions of Section 5-1401 of the New York General Obligations
Law), and the obligations, rights and remedies of the Holder hereof shall be
determined in accordance with such laws.

THE CLASS OF CERTIFICATES TO WHICH THIS CERTIFICATE BELONGS IS SUBORDINATE TO
ONE OR MORE OTHER CLASSES OF CERTIFICATES OF THE SAME SERIES, AS AND TO THE
EXTENT PROVIDED IN THE POOLING AND SERVICING AGREEMENT REFERRED TO HEREIN.

SOLELY FOR U.S. FEDERAL INCOME TAX PURPOSES, THIS CERTIFICATE IS A "REGULAR
INTEREST" IN A "REAL ESTATE MORTGAGE INVESTMENT CONDUIT" (A "REMIC") AS THOSE
TERMS ARE DEFINED, RESPECTIVELY, IN SECTIONS 860G AND 860D OF THE CODE.

THE OUTSTANDING CERTIFICATE PRINCIPAL BALANCE HEREOF AT ANY TIME MAY BE LESS
THAN THE AMOUNT SHOWN ABOVE.

         This certifies that Cede & Co. is the registered owner of the
Percentage Interest evidenced by this Certificate (obtained by dividing the
principal balance of this Certificate (its "Certificate Principal Balance") as
of the Closing Date by the aggregate principal balance of all the Certificates
of the same Class as this Certificate (their "Class Principal Balance") as of
the Closing Date) in that certain beneficial ownership interest in the Trust
evidenced by all the Certificates of the same Class as this Certificate. The
Trust was created and the Certificates were issued pursuant to a Pooling and
Servicing Agreement, dated as specified above (the "Agreement"), between
Structured Asset Securities Corporation II, as depositor (the "Depositor", which
term includes any successor entity under the Agreement), Wachovia Bank, National
Association, as master servicer (the "Master Servicer", which term includes any
successor entity under the Agreement), Lennar Partners, Inc., as special
servicer (the "Special Servicer", which term includes any successor entity under
the Agreement), LaSalle Bank National Association, as trustee (the "Trustee",
which term includes any successor entity under the Agreement) and ABN AMRO Bank
N.V., as fiscal agent (the "Fiscal Agent", which term includes any successor
entity under the Agreement), a summary of certain of the pertinent provisions of
which is set forth hereafter. To the extent not defined herein, the capitalized
terms used herein have the respective meanings assigned in the Agreement. This
Certificate is issued under and is subject to the terms, provisions and
conditions of the Agreement, to which Agreement the Holder of this Certificate
by virtue of the acceptance hereof assents and by which such Holder is bound. In
the event of any conflict between any provision of this Certificate and any
provision of the Agreement, such provision of this Certificate shall be
superseded to the extent of such inconsistency.

         Pursuant to the terms of the Agreement, distributions will be made on
the 4th Business Day following the 11th calendar day of each month (or, if such
11th calendar day is not a Business Day, then the 5th Business Day following
such 11th calendar day) (each, a "Distribution Date"), commencing on the first
Distribution Date specified above, to the Person in whose name this Certificate
is registered at the close of business on the last Business Day of the month
immediately preceding the month of such distribution (the "Record Date"), in an
amount equal to the product of the Percentage Interest evidenced

                                     A-3-3
<PAGE>

by this Certificate and the amount required to be distributed pursuant to the
Agreement on the applicable Distribution Date in respect of the Class of
Certificates to which this Certificate belongs; provided that the initial Record
Date will be the Closing Date. All distributions made under the Agreement in
respect of this Certificate will be made by the Trustee by wire transfer in
immediately available funds to the account of the Person entitled thereto at a
bank or other entity having appropriate facilities therefor, if such
Certificateholder shall have provided the Trustee with written wiring
instructions no less than five (5) Business Days prior to (or, in the case of
the first such distribution, no later than) the Record Date for such
distribution (which wiring instructions may be in the form of a standing order
applicable to all subsequent distributions as well), or otherwise by check
mailed to the address of such Certificateholder appearing in the Certificate
Register. Notwithstanding the above, the final distribution in respect of this
Certificate (determined without regard to any possible future reimbursement of
any Realized Loss or Additional Trust Fund Expense previously allocated to this
Certificate) will be made after due notice by the Trustee of the pendency of
such distribution and only upon presentation and surrender of this Certificate
at the offices of the Certificate Registrar appointed as provided in the
Agreement or such other location as may be specified in such notice. Also
notwithstanding the foregoing, any distribution that may be made with respect to
this Certificate in reimbursement of any Realized Loss or Additional Trust Fund
Expense previously allocated to this Certificate, which reimbursement is to
occur after the date on which this Certificate is surrendered as contemplated by
the preceding sentence, will be made by check mailed to the address of the
Holder that surrenders this Certificate as such address last appeared in the
Certificate Register or to any such other address of which the Trustee is
subsequently notified in writing.

         Any distribution to the Holder of this Certificate in reduction of the
Certificate Principal Balance hereof is binding on such Holder and all future
Holders of this Certificate and any Certificate issued upon the transfer hereof
or in exchange herefor or in lieu hereof whether or not notation of such
distribution is made upon this Certificate.

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

         The Certificates are issuable in fully registered form only without
coupons in minimum denominations specified in the Agreement. As provided in the
Agreement and subject to certain limitations therein set forth, 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.

         As provided in the Agreement and subject to certain limitations therein
set forth, the transfer of this Certificate is registrable in the Certificate
Register upon surrender of this Certificate for registration of transfer at the
offices of the Certificate Registrar, duly endorsed by, or accompanied by a
written instrument of transfer in the form satisfactory to the Certificate
Registrar duly executed by, the Holder hereof or his attorney duly authorized in
writing, and thereupon one or more new Certificates of

                                     A-3-4
<PAGE>

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 or any interest herein shall be made to
any of the following: (i) Howard L. Melamed or any other fiduciary with respect
to the Howard L. Melamed Profit Sharing Plan; (ii) a person providing services
to the Howard L. Melamed Profit Sharing Plan; (iii) employers who have any
employees covered by the Howard L. Melamed Profit Sharing Plan; (iv) any

or more shareholders of any of the persons mentioned above, except persons who
are fiduciaries or relatives; or (ix) 10% or more partners or joint venturers of
any person listed above, except persons who are fiduciaries or relatives. Any
acquisition or holding of a Certificate by an Ineligible Purchaser shall be void
ab initio and of no force and effect.

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

         [FOR BOOK ENTRY CERTIFICATES:] Notwithstanding the foregoing, for so
long as this Certificate is registered in the name of Cede & Co. or in such
other name as is requested by an authorized representative of DTC, transfers of
interests in this Certificate shall be made through the book-entry facilities of
DTC.

         The Holder of this Certificate, by its acceptance hereof, shall be
deemed to have agreed to keep confidential any information it obtains from the
Trustee (except that such Holder may provide any such information obtained by it
to any other Person that holds or is contemplating the purchase of this
Certificate or an interest herein, provided that such other Person confirms in
writing such ownership interest or prospective ownership interest and agrees to
keep such information confidential). Notwithstanding the foregoing, each offeree
and/or holder of this Certificate (and each employee, representative, or other
agent of such offeree or holder) may disclose to any and all persons, without
limitation of any kind, the tax treatment and tax structure of the transactions
(as defined in section 1.6011-4 of the Treasury Department regulations)
associated herewith and all materials of any kind (including opinions or other
tax analyses) that are provided to the taxpayer relating to such tax treatment
and tax structure.

         Prior to due presentment of this Certificate for registration of
transfer, the Depositor, the Master Servicer, the Special Servicer, the Trustee,
the Fiscal Agent, the Certificate Registrar and any agents of any of them may
treat the Person in whose name this Certificate is registered as the owner
hereof for all purposes, and none of the Depositor, the Master Servicer, the
Special Servicer, the Trustee, the Fiscal Agent, the Certificate Registrar or
any such agent shall be affected by notice to the contrary.

         Subject to certain terms and conditions set forth in the Agreement, the
Trust and the obligations created by the Agreement shall terminate upon
distribution (or provision for distribution) to the Certificateholders of all
amounts held by or on behalf of the Trustee and required to be distributed to

                                     A-3-5
<PAGE>

them pursuant to the Agreement following the earlier of (i) the final payment
(or any advance with respect thereto) on or other liquidation of the last
Mortgage Loan or REO Property remaining in the Trust, and (ii) the purchase by
the Depositor, Lehman Brothers Inc., the Master Servicer, the Special Servicer
or any Controlling Class Certificateholder at a price determined as provided in
the Agreement of all Mortgage Loans and any REO Properties remaining in the
Trust. The Agreement permits, but does not require, the Depositor, Lehman
Brothers Inc., the Master Servicer, the Special Servicer or any Controlling
Class Certificateholder to purchase from the Trust all Mortgage Loans and any
REO Properties remaining therein. The exercise of such right will effect early
retirement of the Certificates; however, such right to purchase is subject to
the aggregate Stated Principal Balance of the Mortgage Pool at the time of
purchase being less than approximately 1.0% of the aggregate Certificate
Principal Balance of all the Principal Balance Certificates as of the Closing
Date. In addition, following the date on which the total principal balance of
the Class A-1, A-2, A-3, A-4, B, C, D, E, F and G Certificates is reduced to
zero, any single Holder or group of Holders of all of the remaining Certificates
may, with the consent of the Master Servicer and subject to such other
conditions as may be set forth in the Agreement, exchange those Certificates for
all Mortgage Loans and REO Properties remaining in the Trust Fund at the time of
the exchange.

         The Agreement permits, with certain exceptions therein provided, the

set forth, the transfer of this Certificate is registrable in the Certificate
Register upon surrender of this Certificate for registration of transfer at the
offices of the Certificate Registrar, duly endorsed by, or accompanied by a

be issued to the designated transferee or transferees.

         No direct or indirect transfer, sale, pledge, hypothecation or other
disposition (each, a "Transfer") of this Certificate or any interest herein
shall be made unless that Transfer is exempt from the registration and/or
qualification requirements of the Securities Act and any applicable state
securities laws, or is otherwise made in accordance with the Securities Act and
such state securities laws.

         If this Certificate constitutes a Definitive Certificate and a Transfer
hereof is to be made without registration under the Securities Act (other than
in connection with the initial issuance of the Certificates or a Transfer of
this Certificate by the Depositor, Lehman Brothers Inc. or any of their
respective Affiliates or, if this Certificate is a Global Certificate, a
Transfer of this Certificate to a successor Depository or to the applicable
Certificate Owner in accordance with Section 5.03 of the Agreement), then the
Certificate Registrar shall refuse to register such Transfer unless it receives
(and, upon receipt, may conclusively rely upon) either: (i) a certificate from
the Certificateholder desiring to effect such Transfer substantially in the form
attached as Exhibit F-1 to the Agreement and a certificate from such
Certificateholder's prospective Transferee substantially in the form attached
either as Exhibit F-2A to the Agreement or as Exhibit F-2B to the Agreement; or
(ii) an Opinion of Counsel satisfactory to the Trustee to the effect that such
Transferee is an Institutional Accredited Investor or a Qualified Institutional
Buyer and such Transfer may be made without registration under the Securities
Act (which Opinion of Counsel shall not be an expense of the Trust Fund or of
the Depositor, the Master Servicer, the Special Servicer, the Trustee, the
Fiscal Agent or the Certificate Registrar in their respective capacities as
such), together with the written certification(s) as to the facts surrounding
such Transfer from the Certificateholder desiring to effect such Transfer and/or
such Certificateholder's prospective Transferee on which such Opinion of Counsel
is based. If any Transferee of this Certificate does not, in connection with the
subject Transfer, deliver to the Certificate Registrar one of the certifications
described in clause (i) of the preceding sentence or the Opinion of Counsel
described in clause (ii) of the preceding sentence, then such Transferee shall
be deemed to have represented and warranted that all the

                                     A-4-5
<PAGE>

certifications set forth in either Exhibit F-2A or Exhibit F-2B attached to the
Agreement are, with respect to the subject Transfer, true and correct.

         If this Certificate constitutes a Rule 144A Global Certificate and a
Transfer of any interest herein is to be made without registration under the
Securities Act (other than in connection with the initial issuance of the
Certificates or a Transfer of any interest herein by the Depositor, Lehman
Brothers Inc. or any of their respective Affiliates), then the Certificate Owner
desiring to effect such Transfer shall be required to obtain either (i) a
certificate from such Certificate Owner's prospective Transferee substantially
in the form attached as Exhibit F-2C to the Agreement, or (ii) an Opinion of
Counsel to the effect that such Transferee is a Qualified Institutional Buyer
and such Transfer may be made without registration under the Securities Act.
Except as discussed below, an interest in a Rule 144A Global Certificate for any
Class of Book-Entry Non-Registered Certificates may not be transferred to any
Person who takes delivery other than in the form of an interest in such Rule
144A Global Certificate. If this Certificate constitutes a Rule 144A Global
Certificate and any Transferee of an interest herein does not, in connection
with the subject Transfer, deliver to the Transferor the Opinion of Counsel or
the certification described in the second preceding sentence, then such
Transferee shall be deemed to have represented and warranted that all the
certifications set forth in Exhibit F-2C attached to the Agreement are, with
respect to the subject Transfer, true and correct.

         Notwithstanding the preceding paragraph, any interest in a Rule 144A
Global Certificate for a Class of Book-Entry Non-Registered Certificates may be
transferred (without delivery of any certificate or Opinion of Counsel described
in clauses (i) and (ii) of the first sentence of the preceding paragraph) by the
Depositor or any Affiliate of the Depositor to any Person who takes delivery in
the form of a beneficial interest in the Regulation S Global Certificate for
such Class of Certificates upon delivery to the Certificate Registrar of (x) a
certificate to the effect that the Certificate Owner desiring to effect such
Transfer is the Depositor or an Affiliate of the Depositor and (y) such written
orders and instructions as are required under the applicable procedures of the
Depository, Clearstream and Euroclear to direct the Trustee to debit the account
of a Depository Participant by a denomination of interests in such Rule 144A
Global Certificate, and credit the account of a Depository Participant by a
denomination of interests in such Regulation S Global Certificate, that is equal
to the denomination of beneficial interests in the subject Class of Certificates
to be transferred. Upon delivery to the Certificate Registrar of such
certification and such orders and instructions, the Trustee, subject to and in
accordance with the applicable procedures of the Depository, shall reduce the
denomination of the Rule 144A Global Certificate in respect of the subject Class
of Certificates and increase the denomination of the Regulation S Global
Certificate for such Class, by the denomination of the beneficial interest in
such Class specified in such orders and instructions.

         Also notwithstanding the second preceding paragraph, any interest in a
Rule 144A Global Certificate with respect to any Class of Book-Entry
Non-Registered Certificates may be transferred by any Certificate Owner holding
such interest to any Institutional Accredited Investor (other than a Qualified
Institutional Buyer) that takes delivery in the form of a Definitive Certificate
of the same Class as such Rule 144A Global Certificate upon delivery to the
Certificate Registrar and the Trustee of (i) such certifications and/or opinions
as are contemplated by the third preceding paragraph, (ii) a certification from
such Certificate Owner to the effect that it is the lawful owner of the
beneficial interest being transferred and (iii) such written orders and
instructions as are required under the applicable procedures of the Depository
to direct the Trustee to debit the account of a Depository Participant by the
denomination of the transferred interests in such Rule 144A Global Certificate.
Upon

                                     A-4-6
<PAGE>

delivery to the Certificate Registrar of such certifications and/or opinions and
such orders and instructions, the Trustee, subject to and in accordance with the
applicable procedures of the Depository, shall reduce the denomination of the
subject Rule 144A Global Certificate by the denomination of the transferred
interests in such Rule 144A Global Certificate, and shall cause a Definitive
Certificate of the same Class as such Rule 144A Global Certificate, and in a
denomination equal to the reduction in the denomination of such Rule 144A Global
Certificate, to be executed, authenticated and delivered in accordance with the
Agreement to the applicable Transferee.

         Except as provided in the next paragraph no beneficial interest in a
Regulation S Global Certificate for any Class of Book-Entry Non-Registered
Certificates shall be transferred to any Person who takes delivery other than in
the form of a beneficial interest in such Regulation S Global Certificate. On
and prior to the Release Date, the Certificate Owner desiring to effect any such
Transfer shall be required to obtain from such Certificate Owner's prospective
Transferee a written certification substantially in the form set forth in
Exhibit F-2D to the Agreement certifying that such Transferee is not a United
States Securities Person. On or prior to the Release Date, beneficial interests
in the Regulation S Global Certificate for each Class of Book-Entry
Non-Registered Certificates may be held only through Euroclear or Clearstream.

         Notwithstanding the preceding paragraph, any interest in a Regulation S
Global Certificate for a Class of Book-Entry Non-Registered Certificates may be
transferred by the Depositor or any Affiliate of the Depositor to any Person who
takes delivery in the form of a beneficial interest in the Rule 144A Global
Certificate for such Class of Certificates upon delivery to the Certificate
Registrar of (x) a certificate to the effect that the Certificate Owner desiring
to effect such Transfer is the Depositor or an Affiliate of the Depositor and
(y) such written orders and instructions as are required under the applicable
procedures of the Depository, Clearstream and Euroclear to direct the Trustee to
debit the account of a Depository Participant by a denomination of interests in
such Regulation S Global Certificate, and credit the account of a Depository
Participant by a denomination of interests in such Rule 144A Global Certificate,
that is equal to the denomination of beneficial interests in the subject Class

exchange of Certificates, but the Trustee or the Certificate Registrar may
require payment of a sum sufficient to cover any tax or other governmental
charge that may be imposed in connection with any transfer or exchange of
Certificates.

         [FOR BOOK ENTRY CERTIFICATES:] Notwithstanding the foregoing, for so
long as this Certificate is registered in the name of Cede & Co. or in such
other name as is requested by an authorized representative of DTC, transfers of
interests in this Certificate shall be made through the book-entry facilities of
DTC.

         The Holder of this Certificate, by its acceptance hereof, shall be
deemed to have agreed to keep confidential any information it obtains from the
Trustee (except that such Holder may provide any such information obtained by it
to any other Person that holds or is contemplating the purchase of this
Certificate or an interest herein, provided that such other Person confirms in
writing such ownership interest or prospective ownership interest and agrees to
keep such information confidential). Notwithstanding the foregoing, each offeree
and/or holder of this Certificate (and each employee, representative, or other
agent of such offeree or holder) may disclose to any and all persons, without
limitation of any kind, the tax treatment and tax structure of the transactions
(as defined in section 1.6011-4 of the Treasury Department regulations)
associated herewith and all materials of any kind (including opinions or other
tax analyses) that are provided to the taxpayer relating to such tax treatment
and tax structure.

         Prior to due presentment of this Certificate for registration of
transfer, the Depositor, the Master Servicer, the Special Servicer, the Trustee,
the Fiscal Agent, the Certificate Registrar and any agents of any of them may
treat the Person in whose name this Certificate is registered as the owner
hereof for all purposes, and none of the Depositor, the Master Servicer, the
Special Servicer, the Trustee, the Fiscal Agent, the Certificate Registrar or
any such agent shall be affected by notice to the contrary.

         Subject to certain terms and conditions set forth in the Agreement, the
Trust and the obligations created by the Agreement shall terminate upon
distribution (or provision for distribution) to

                                     A-4-9
<PAGE>

the Certificateholders of all amounts held by or on behalf of the Trustee and
required to be distributed to them pursuant to the Agreement following the
earlier of (i) the final payment (or any advance with respect thereto) on or
other liquidation of the last Mortgage Loan or REO Property remaining in the
Trust, and (ii) the purchase by the Depositor, Lehman Brothers Inc., the Master
Servicer, the Special Servicer or any Controlling Class Certificateholder at a
price determined as provided in the Agreement of all Mortgage Loans and any REO
Properties remaining in the Trust. The Agreement permits, but does not require,
the Depositor, Lehman Brothers Inc., the Master Servicer, the Special Servicer
or any Controlling Class Certificateholder to purchase from the Trust all
Mortgage Loans and any REO Properties remaining therein. The exercise of such
right will effect early retirement of the Certificates; however, such right to
purchase is subject to the aggregate Stated Principal Balance of the Mortgage
Pool at the time of purchase being less than approximately 1.0% of the aggregate
Certificate Principal Balance of all the Principal Balance Certificates as of
the Closing Date. In addition, following the date on which the total principal
balance of the Class A-1, A-2, A-3, A-4, B, C, D, E, F and G Certificates is
reduced to zero, any single Holder or group of Holders of all of the remaining
Certificates may, with the consent of the Master Servicer and subject to such
other conditions as may be set forth in the Agreement, exchange those
Certificates for all Mortgage Loans and REO Properties remaining in the Trust
Fund at the time of the exchange.

         The Agreement permits, with certain exceptions therein provided, the
amendment thereof, and the modification of the rights and obligations of the
Depositor, the Master Servicer, the Special Servicer, the Trustee and the Fiscal
Agent thereunder and the rights of the Certificateholders thereunder, at any
time by the Depositor, the Master Servicer, the Special Servicer, the Trustee
and the Fiscal Agent with the consent of the Holders of Certificates entitled to
at least 66-2/3% of the Voting Rights allocated to the affected Classes. Any
such consent by the Holder of this Certificate shall be conclusive and binding
on such Holder and upon all future Holders of this Certificate and of any
Certificate issued upon the transfer hereof or in exchange herefor or in lieu
hereof whether or not notation of such consent is made upon this Certificate.
The Agreement also permits the amendment thereof, in certain circumstances,
including any amendment necessary to maintain the status of any REMIC Pool as a
REMIC, without the consent of the Holders of any of the Certificates.

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

         The registered Holder hereof, by its acceptance hereof, agrees that it
will look solely to the Trust (to the extent of its rights therein) for
distributions hereunder.

         This Certificate shall be construed in accordance with the internal
laws of the State of New York applicable to agreements made and to be performed
in said State, without applying any conflicts of law principles of such state
(other than the provisions of Section 5-1401 of the New York General Obligations
Law), and the obligations, rights and remedies of the Holder hereof shall be
determined in accordance with such laws.

Certificateholder's prospective Transferee substantially in the form attached

                                     A-5-4
<PAGE>

be an expense of the Trust Fund or of the Depositor, the Master Servicer, the
Special Servicer, the Trustee, the Fiscal Agent or the Certificate Registrar in
their respective capacities as such), together with the written certification(s)
as to the facts surrounding such Transfer from the Certificateholder desiring to

does not, in connection with the subject Transfer, deliver to the Certificate
Registrar one of the certifications described in clause (i) of the preceding
sentence or the Opinion of Counsel described in clause (ii) of the preceding
sentence, then such Transferee shall be deemed to have represented and warranted
that all the certifications set forth in either Exhibit F-2A or Exhibit F-2B
attached to the Agreement are, with respect to the subject Transfer, true and
correct.

         None of the Depositor, the Trustee or the Certificate Registrar is
obligated to register or qualify the Class of Certificates to which this
Certificate belongs, under the Securities Act or any other securities law or to
take any action not otherwise required under the Agreement to permit the
Transfer of this Certificate or any interest herein without such registration or
qualification. Any Certificateholder desiring to effect a Transfer of this
Certificate or any interest herein shall, and does hereby agree to, indemnify
the Depositor, Lehman Brothers Inc., UBS Securities LLC, the Trustee, the Master
Servicer, the Special Servicer, the Fiscal Agent, the Certificate Registrar and
their respective Affiliates against any liability that may result if such
Transfer is not exempt from the registration and/or qualification requirements
of the Securities Act and any applicable state securities laws or is not made in
accordance with such federal and state laws.

individual retirement accounts and annuities, Keogh plans and collective
investment funds and separate accounts in which such plans, accounts or

subject to ERISA or the Code (each, a "Plan"), or (B) any Person who is directly
or indirectly purchasing this Certificate or such interest herein on behalf of,
as named fiduciary of, as trustee of, or with assets of a Plan, if the purchase

4975 of the Code or would result in the imposition of an excise tax under
Section 4975 of the Code. Furthermore, no transfer of this Certificate or any
interest herein shall be made to any of the following Ineligible Purchasers: (i)

Certificate or such interest herein

                                     A-5-5
<PAGE>

on behalf of an Ineligible Purchaser and (y) one of the following: (i) a
certification to the effect that such prospective Transferee is not a Plan and
is not directly or indirectly purchasing this Certificate on behalf of, as named
fiduciary of, as trustee of, or with assets of a Plan; or (ii) a certification
of facts and an Opinion of Counsel which otherwise establish to the reasonable
satisfaction of the Trustee that such Transfer will not result in a violation of
Section 406 or 407 of ERISA or Section 4975 of the Code or result in the
imposition of an excise tax under Section 4975 of the Code. If any Transferee of
this Certificate or any interest herein does not, in connection with the subject
Transfer, deliver to the Certificate Registrar a certification and/or Opinion of
Counsel as required by the preceding sentence, then such Transferee shall be
deemed to have represented and warranted that (a) such Transferee is not an
Ineligible Purchaser and (b) either (i) such Transferee is not a Plan and is not
directly or indirectly purchasing this Certificate or such interest herein on
behalf of, as named fiduciary of, as trustee of, or with assets of a Plan; or
(ii) the purchase and holding of this Certificate or such interest herein by
such Transferee is exempt from the prohibited transaction provisions of Sections
406(a) and (b) and 407 of ERISA and the excise taxes imposed on such prohibited
transactions by Sections 4975(a) and (b) of the Code. Any acquisition or holding
of a Certificate by an Ineligible Purchaser shall be void ab initio and of no
force and effect.

         Each Person who has or who acquires any Ownership Interest in this
Certificate shall be deemed by the acceptance or acquisition of such Ownership
Interest to have agreed to be bound by the provisions of Section 5.02(d) of the
Agreement and, if any purported Transferee shall become a Holder of this
Certificate in violation of the provisions of such Section 5.02(d), to have
irrevocably authorized the Trustee under clause (ii)(A) of such Section 5.02(d)
to deliver payments to a Person other than such Person and to have irrevocably
authorized the Trustee under clause (ii)(B) of such Section 5.02(d) to negotiate
the terms of any mandatory disposition and to execute all instruments of
transfer and to do all other things necessary in connection with any such
disposition. Each Person holding or acquiring any Ownership Interest in this
Certificate must be a Permitted Transferee and shall promptly notify the Trustee
and the Tax Administrator of any change or impending change in its status as a
Permitted Transferee. In connection with any proposed Transfer of any Ownership
Interest in this Certificate, the Certificate Registrar shall require delivery
to it, and shall not register the transfer of this Certificate until its receipt
of, an affidavit and agreement substantially in the form attached as Exhibit H-1
to the Agreement (a "Transfer Affidavit and Agreement") from the proposed
Transferee, representing and warranting, among other things, that such
Transferee is a Permitted Transferee, that it is not acquiring its Ownership
Interest in this Certificate as a nominee, trustee or agent for any Person that
is not a Permitted Transferee, that for so long as it retains its Ownership
Interest in this Certificate, it will endeavor to remain a Permitted Transferee,
and that it has reviewed the provisions of Section 5.02(d) of the Agreement and
agrees to be bound by them. Notwithstanding the delivery of a Transfer Affidavit
and Agreement by a proposed Transferee, if the Certificate Registrar has actual
knowledge that the proposed Transferee is not a Permitted Transferee, the
Certificate Registrar shall not register the Transfer of an Ownership Interest
in this Certificate to such proposed Transferee. In addition, the Certificate
Registrar shall not register the transfer of an Ownership Interest in this
Certificate to any entity classified as a partnership under the Code unless at
the time of transfer, all of its beneficial owners are United States Tax
Persons.

         Each Person holding or acquiring any Ownership Interest in this
Certificate shall agree (x) to require a Transfer Affidavit and Agreement from
any other Person to whom such Person attempts to Transfer its Ownership Interest
herein and (y) not to Transfer its Ownership Interest herein unless it provides
to the Certificate Registrar a certificate substantially in the form attached as
Exhibit H-2 to the

                                     A-5-6
<PAGE>

Agreement stating that, among other things, it has no actual knowledge that such
other Person is not a Permitted Transferee. Each Person holding or acquiring an
Ownership Interest in this Certificate, by purchasing such Ownership Interest
herein, agrees to give the Trustee and the Tax Administrator written notice that
it is a "pass-through interest holder" within the meaning of temporary Treasury
regulations section 1.67-3T(a)(2)(i)(A) immediately upon acquiring such
Ownership Interest, if it is, or is holding such Ownership Interest on behalf
of, a "pass-through interest holder".

         The provisions of Section 5.02(d) of the Agreement may be modified,
added to or eliminated, provided that there shall have been delivered to the
Trustee and the Tax Administrator the following: (a) written notification from
each Rating Agency to the effect that the modification of, addition to or
elimination of such provisions will not cause such Rating Agency to withdraw,
qualify or downgrade its then-current rating of any Class of Certificates; and
(b) an opinion of counsel, in form and substance satisfactory to the Trustee and
the Tax Administrator, to the effect that such modification of, addition to or
elimination of such provisions will not (i) cause any REMIC Pool to (A) cease to
qualify as a REMIC or (B) be subject to an entity-level tax caused by the
Transfer of a Residual Interest Certificate to a Person which is not a Permitted
Transferee, or (ii) cause a Person other than the prospective Transferee to be
subject to a REMIC-related tax caused by the Transfer of a Residual Interest
Certificate to a Person that is not a Permitted Transferee.

         A "Permitted Transferee" is any Transferee that is not (i) a
Disqualified Organization, (ii) any Person as to whom the transfer of this
Certificate may cause any REMIC Pool to fail to qualify as a REMIC, (iii) a
Disqualified Non-United States Tax Person, (iv) a Disqualified Partnership or
(v) a foreign permanent establishment or fixed base (within the meaning of any
applicable income tax treaty between the United States and any foreign
jurisdiction) of a United States Tax Person.

         A "Disqualified Organization" is (i) the United States, any State or
political subdivision thereof, a foreign government, an international
organization, or any agency or instrumentality of any of the foregoing, (ii) any
organization (other than certain farmers' cooperatives described in Section 521
of the Code) that is exempt from the tax imposed by Chapter 1 of the Code
(including the tax imposed by Section 511 of the Code on unrelated business
taxable income), (iii) rural electric and telephone cooperatives described in
Section 1381 of the Code and (iv) any other Person so designated by the Trustee
or the Tax Administrator based upon an opinion of counsel that the holding of an
Ownership Interest in a Residual Interest Certificate by such Person may cause
the Trust or any Person having an Ownership Interest in any Class of
Certificates (other than such Person) to incur a liability for any federal tax
imposed under the Code that would not otherwise be imposed but for the Transfer
of an Ownership Interest in a Residual Interest Certificate to such Person. The
terms "United States", "State" and "international organization" shall have the
meanings set forth in Section 7701 of the Code or successor provisions.

         A "Disqualified Non-United States Tax Person" is, with respect to any
Residual Interest Certificate, any Non-United States Tax Person or agent thereof
other than: (1) a Non-United States Tax Person that (a) holds such Residual
Interest Certificate and, for purposes of Treasury regulations section
1.860G-3(a)(3), is subject to tax under Section 882 of the Code, (b) certifies
that it understands that, for purposes of Treasury regulations section
1.860E-1(c)(4)(ii), as a holder of such Residual Interest Certificate for United
States federal income tax purposes, it may incur tax liabilities in excess of
any cash flows generated by such Residual Interest Certificate and intends to
pay taxes associated with holding such Residual Interest Certificate, and (c)
has furnished the Transferor and the Trustee with an

                                     A-5-7
<PAGE>

effective IRS Form W-8ECI or successor form and has agreed to update such form
as required under the applicable Treasury regulations; or (2) a Non-United
States Tax Person that has delivered to the Transferor, the Trustee and the
Certificate Registrar an opinion of nationally recognized tax counsel to the
effect that (x) the Transfer of such Residual Interest Certificate to it is in
accordance with the requirements of the Code and the regulations promulgated
thereunder and (y) such Transfer of such Residual Interest Certificate will not
be disregarded for United States federal income tax purposes.

         A "Disqualified Partnership" is any domestic entity classified as a
partnership under the Code, if any of its beneficial owners are Disqualified
Non-United States Tax Persons.

         A "Non-United States Tax Person" is any Person other than a United
States Tax Person. A "United States Tax Person" 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 whose income from sources without the United States is
includable 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, or a trust if a court within the United States is able to
exercise supervision over the administration of the trust and one or more United
States persons have the authority to control all substantial decisions of the
trust (or to the extent provided in the Treasury regulations, if the trust was
in existence on August 20, 1996 and elected to be treated as a United States
person), all within the meaning of Section 7701(a)(30) of the Code.

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

         The Holder of this Certificate, by its acceptance hereof, shall be
deemed to have agreed to keep confidential any information it obtains from the
Trustee (except that such Holder may provide any such information obtained by it
to any other Person that holds or is contemplating the purchase of this
Certificate or an interest herein, provided that such other Person confirms in
writing such ownership interest or prospective ownership interest and agrees to
keep such information confidential). Notwithstanding the foregoing, each offeree
and/or holder of this Certificate (and each employee, representative, or other
agent of such offeree or holder) may disclose to any and all persons, without
limitation of any kind, the tax treatment and tax structure of the transactions
(as defined in section 1.6011-4 of the Treasury Department regulations)
associated herewith and all materials of any kind (including opinions or other
tax analyses) that are provided to the taxpayer relating to such tax treatment
and tax structure.

         Prior to due presentment of this Certificate for registration of
transfer, the Depositor, the Master Servicer, the Special Servicer, the Trustee,
the Fiscal Agent, the Certificate Registrar and any agents of any of them may
treat the Person in whose name this Certificate is registered as the owner
hereof for all purposes, and none of the Depositor, the Master Servicer, the
Special Servicer, the Trustee, the Fiscal Agent, the Certificate Registrar or
any such agent shall be affected by notice to the contrary.

         Subject to certain terms and conditions set forth in the Agreement, the
Trust and the obligations created by the Agreement shall terminate upon
distribution (or provision for distribution) to the Certificateholders of all
amounts held by or on behalf of the Trustee and required to be distributed to
them pursuant to the Agreement following the earlier of (i) the final payment
(or any advance with

                                     A-5-8
<PAGE>

respect thereto) on or other liquidation of the last Mortgage Loan or REO
Property remaining in the Trust, and (ii) the purchase by the Depositor, Lehman
Brothers Inc., the Master Servicer, the Special Servicer or any Controlling
Class Certificateholder at a price determined as provided in the Agreement of
all Mortgage Loans and any REO Properties remaining in the Trust. The Agreement
permits, but does not require, the Depositor, Lehman Brothers Inc., the Master
Servicer, the Special Servicer or any Controlling Class Certificateholder to
purchase from the Trust all Mortgage Loans and any REO Properties remaining
therein. The exercise of such right will effect early retirement of the
Certificates; however, such right to purchase is subject to the aggregate Stated
Principal Balance of the Mortgage Pool at the time of purchase being less than
approximately 1.0% of the aggregate Certificate Principal Balance of all the
Principal Balance Certificates as of the Closing Date. In addition, following
the date on which the total principal balance of the Class A-1, A-2, A-3, A-4,
B, C, D, E, F and G Certificates is reduced to zero, any single Holder or group
of Holders of all of the remaining Certificates may, with the consent of the
Master Servicer and subject to such other conditions as may be set forth in the
Agreement, exchange those Certificates for all Mortgage Loans and REO Properties
remaining in the Trust Fund at the time of the exchange.

         The Agreement permits, with certain exceptions therein provided, the
amendment thereof, and the modification of the rights and obligations of the
Depositor, the Master Servicer, the Special Servicer, the Trustee and the Fiscal
Agent thereunder and the rights of the Certificateholders thereunder, at any
time by the Depositor, the Master Servicer, the Special Servicer, the Trustee
and the Fiscal Agent with the consent of the Holders of Certificates entitled to
at least 66-2/3% of the Voting Rights allocated to the affected Classes. Any
such consent by the Holder of this Certificate shall be conclusive and binding
on such Holder and upon all future Holders of this Certificate and of any
Certificate issued upon the transfer hereof or in exchange herefor or in lieu
hereof whether or not notation of such consent is made upon this Certificate.
The Agreement also permits the amendment thereof, in certain circumstances,
including any amendment necessary to maintain the status of any REMIC Pool as a
REMIC, without the consent of the Holders of any of the Certificates.

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

         The registered Holder hereof, by its acceptance hereof, agrees that it
will look solely to the Trust (to the extent of its rights therein) for
distributions hereunder.

         This Certificate shall be construed in accordance with the internal
laws of the State of New York applicable to agreements made and to be performed
in said State, without applying any conflicts of law principles of such state
(other than the provisions of Section 5-1401 of the New York General Obligations
Law), and the obligations, rights and remedies of the Holder hereof shall be
determined in accordance with such laws.

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

THIS CERTIFICATE IS ENTITLED ONLY TO CERTAIN ADDITIONAL INTEREST (IF ANY)
RECEIVED IN RESPECT OF THE ARD TRUST MORTGAGE LOANS SUBJECT TO THE POOLING AND
SERVICING AGREEMENT REFERRED TO HEREIN.

         This certifies that ________________________________ is the registered
owner of the Percentage Interest evidenced by this Certificate (as specified
above) in that certain beneficial ownership interest in the Trust evidenced by
all the Class V Certificates. The Trust was created and the Certificates were
issued pursuant to a Pooling and Servicing Agreement, dated as specified above
(the "Agreement"), between Structured Asset Securities Corporation II, as
depositor (the "Depositor", which term includes any successor entity under the
Agreement), Wachovia Bank, National Association, as master servicer (the "Master
Servicer", which term includes any successor entity under the Agreement), Lennar
Partners, Inc., as special servicer (the "Special Servicer", which term includes
any successor entity under the Agreement), LaSalle Bank National Association, as
trustee (the "Trustee", which term includes any successor entity under the
Agreement) and ABN AMRO Bank N.V., as fiscal agent (the "Fiscal Agent", which
term includes any successor entity under the Agreement), a summary of certain of
the pertinent provisions of which is set forth hereafter. To the extent not
defined herein, the capitalized terms used herein have the respective meanings
assigned in the Agreement. This Certificate is issued under and is subject to
the terms, provisions and conditions of the Agreement, to which Agreement the
Holder of this Certificate by virtue of the acceptance hereof assents and by
which such Holder is bound. In the event of any conflict between any provision
of this Certificate and any provision of the Agreement, such provision of this
Certificate shall be superseded to the extent of such inconsistency.

         Pursuant to the terms of the Agreement, distributions will be made on
the 4th Business Day following the 11th calendar day of each month (or, if such
11th calendar day is not a Business Day, then the 5th Business Day following
such 11th calendar day) (each, a "Distribution Date"), commencing on the first
Distribution Date specified above, to the Person in whose name this Certificate
is registered at the close of business on the last Business Day of the month
immediately preceding the month of such distribution (the "Record Date"), in an
amount equal to the product of the Percentage Interest evidenced by this
Certificate and the amount required to be distributed pursuant to the Agreement
on the applicable Distribution Date in respect of the Class of Certificates to
which this Certificate belongs; provided that the initial Record Date will be
the Closing Date. All distributions made under the Agreement in respect of this
Certificate will be made by the Trustee by wire transfer in immediately
available funds to the account of the Person entitled thereto at a bank or other
entity having appropriate facilities therefor, if such Certificateholder shall
have provided the Trustee with written wiring instructions no less than five (5)
Business Days prior to (or, in the case of the first such distribution, no later
than) the Record Date for such distribution (which wiring instructions may be in
the form of a standing order applicable to all subsequent distributions as
well), or otherwise by check mailed to the address of such Certificateholder
appearing in the Certificate Register. Notwithstanding the above, the final
distribution in respect of this Certificate will be made after due notice by the
Trustee of the pendency of such distribution and only upon presentation and
surrender of this Certificate at the offices of the Certificate Registrar
appointed as provided in the Agreement or such other location as may be
specified in such notice.

         The Certificates are limited in right of distribution to certain
collections and recoveries respecting the Mortgage Loans, all as more
specifically set forth herein and in the Agreement. As provided in the
Agreement, withdrawals from the Custodial Accounts, the Collection Account and,
if established, the REO Accounts may be made from time to time for purposes
other than, and, in certain cases, prior to, distributions to
Certificateholders, such purposes including the reimbursement of

                                     A-6-3
<PAGE>

advances made, or certain expenses incurred, with respect to the Mortgage Loans
and the payment of interest on such advances and expenses.

         The Certificates are issuable in fully registered form only without
coupons in minimum denominations specified in the Agreement. As provided in the
Agreement and subject to certain limitations therein set forth, 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.

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

         No direct or indirect transfer, sale, pledge, hypothecation or other
disposition (each, a "Transfer") of this Certificate or any interest herein
shall be made unless that Transfer is exempt from the registration and/or
qualification requirements of the Securities Act and any applicable state
securities laws, or is otherwise made in accordance with the Securities Act and
such state securities laws.

         If a Transfer of this Certificate is to be made without registration
under the Securities Act (other than in connection with the initial issuance of
the Certificates or a Transfer of this Certificate by the Depositor, Lehman
Brothers Inc. or any of their respective Affiliates), then the Certificate
Registrar shall refuse to register such Transfer unless it receives (and, upon
receipt, may conclusively rely upon) either: (i) a certificate from the
Certificateholder desiring to effect such Transfer substantially in the form
attached as Exhibit F-1 to the Agreement and a certificate from such
Certificateholder's prospective Transferee substantially in the form attached
either as Exhibit F-2A to the Agreement or as Exhibit F-2B to the Agreement; or
(ii) an Opinion of Counsel satisfactory to the Trustee to the effect that such
Transferee is an Institutional Accredited Investor or a Qualified Institutional
Buyer and such Transfer may be made without registration under the Securities
Act (which Opinion of Counsel shall not be an expense of the Trust Fund or of
the Depositor, the Master Servicer, the Special Servicer, the Trustee, the
Fiscal Agent or the Certificate Registrar in their respective capacities as
such), together with the written certification(s) as to the facts surrounding
such Transfer from the Certificateholder desiring to effect such Transfer and/or
such Certificateholder's prospective Transferee on which such Opinion of Counsel
is based. If any Transferee of this Certificate does not, in connection with the
subject Transfer, deliver to the Certificate Registrar one of the certifications
described in clause (i) of the preceding sentence or the Opinion of Counsel
described in clause (ii) of the preceding sentence, then such Transferee shall
be deemed to have represented and warranted that all the certifications set
forth in either Exhibit F-2A or Exhibit F-2B attached to the Agreement are, with
respect to the subject Transfer, true and correct.

         None of the Depositor, the Trustee or the Certificate Registrar is
obligated to register or qualify the Class of Certificates to which this
Certificate belongs, under the Securities Act or any other securities law or to
take any action not otherwise required under the Agreement to permit the
Transfer of this Certificate or any interest herein without such registration or
qualification. Any Certificateholder

                                     A-6-4
<PAGE>

desiring to effect a Transfer of this Certificate or any interest herein shall,
and does hereby agree to, indemnify the Depositor, Lehman Brothers Inc., UBS
Securities LLC, the Trustee, the Master Servicer, the Special Servicer, the
Fiscal Agent, the Certificate Registrar and their respective Affiliates against
any liability that may result if such Transfer is not exempt from the
registration and/or qualification requirements of the Securities Act and any
applicable state securities laws or is not made in accordance with such federal
and state laws.

         No Transfer of this Certificate or any interest herein shall be made to
(A) any employee benefit plan or other retirement arrangement, including
individual retirement accounts and annuities, Keogh plans and collective
investment funds and separate accounts in which such plans, accounts or
arrangements are invested, including insurance company general accounts, that is
subject to ERISA or the Code (each, a "Plan"), or (B) any Person who is directly
or indirectly purchasing this Certificate or such interest herein on behalf of,
as named fiduciary of, as trustee of, or with assets of a Plan, if the purchase
and holding of this Certificate or such interest herein by the prospective
Transferee would result in a violation of Section 406 or 407 of ERISA or Section
4975 of the Code or would result in the imposition of an excise tax under
Section 4975 of the Code. Furthermore, no transfer of this Certificate or any
interest herein shall be made to any of the following Ineligible Purchasers: (i)
Howard L. Melamed or any other fiduciary with respect to the Howard L. Melamed
Profit Sharing Plan; (ii) a person providing services to the Howard L. Melamed
Profit Sharing Plan; (iii) employers who have any employees covered by the
Howard L. Melamed Profit Sharing Plan; (iv) any employee organization who has
members covered by the Howard L. Melamed Profit Sharing Plan; (v) an owner of
50% or more of an employer listed in (iii) or an organization listed in (iv);
(vi) spouses, ancestors, lineal descendants, or spouses of lineal descendants of
any of the persons listed above, except persons who are employee organizations;
(vii) corporations, partnerships, trusts or estates of which 50% is owned
directly or indirectly by persons listed above, except persons who are
relatives; (viii) employees, officers, directors or 10% or more shareholders of
any of the persons mentioned above, except persons who are fiduciaries or
relatives; or (ix) 10% or more partners or joint venturers of any person listed
above, except persons who are fiduciaries or relatives. Except in connection
with the initial issuance of the Certificates or any Transfer of this
Certificate by the Depositor, Lehman Brothers Inc. or any of their respective
Affiliates, the Certificate Registrar shall refuse to register the Transfer of
this Certificate unless it has received from the prospective Transferee, (x) a
certification to the effect that such prospective Transferee is not an
Ineligible Purchaser and is not directly or indirectly purchasing this
Certificate or such interest herein on behalf of an Ineligible Purchaser and (y)
one of the following: (i) a certification to the effect that such prospective
Transferee is not a Plan and is not directly or indirectly purchasing this
Certificate or such interest herein on behalf of, as named fiduciary of, as
trustee of, or with assets of a Plan; or (ii) a certification of facts and an
Opinion of Counsel which otherwise establish to the reasonable satisfaction of
the Trustee that such Transfer will not result in a violation of Section 406 or
407 of ERISA or Section 4975 of the Code or result in the imposition of an
excise tax under Section 4975 of the Code. If any Transferee of this Certificate
or any interest herein does not, in connection with the subject Transfer,
deliver to the Certificate Registrar a certification and/or Opinion of Counsel
as required by the preceding sentence, then such Transferee shall be deemed to
have represented and warranted that (a) such Transferee is not an Ineligible
Purchaser and (b) either: (i) such Transferee is not a Plan and is not directly
or indirectly purchasing this Certificate or such interest herein on behalf of,
as named fiduciary of, as trustee of, or with assets of a Plan; or (ii) the
purchase and holding of this Certificate or such interest herein by such
Transferee is exempt from the prohibited transaction provisions of Sections
406(a) and (b) and 407 of ERISA and the excise taxes imposed on such prohibited
transactions by

                                     A-6-5
<PAGE>

Sections 4975(a) and (b) of the Code. Any acquisition or holding of a
Certificate by an Ineligible Purchaser shall be void ab initio and of no force
and effect.

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

         The Holder of this Certificate, by its acceptance hereof, shall be
deemed to have agreed to keep confidential any information it obtains from the
Trustee (except that such Holder may provide any such information obtained by it
to any other Person that holds or is contemplating the purchase of this
Certificate or an interest herein, provided that such other Person confirms in
writing such ownership interest or prospective ownership interest and agrees to
keep such information confidential). Notwithstanding the foregoing, each offeree
and/or holder of this Certificate (and each employee, representative, or other
agent of such offeree or holder) may disclose to any and all persons, without
limitation of any kind, the tax treatment and tax structure of the transactions
(as defined in section 1.6011-4 of the Treasury Department regulations)
associated herewith and all materials of any kind (including opinions or other
tax analyses) that are provided to the taxpayer relating to such tax treatment
and tax structure.

         Prior to due presentment of this Certificate for registration of
transfer, the Depositor, the Master Servicer, the Special Servicer, the Trustee,
the Fiscal Agent, the Certificate Registrar and any agents of any of them may
treat the Person in whose name this Certificate is registered as the owner
hereof for all purposes, and none of the Depositor, the Master Servicer, the
Special Servicer, the Trustee, the Fiscal Agent, the Certificate Registrar or
any such agent shall be affected by notice to the contrary.

         Subject to certain terms and conditions set forth in the Agreement, the
Trust and the obligations created by the Agreement shall terminate upon
distribution (or provision for distribution) to the Certificateholders of all
amounts held by or on behalf of the Trustee and required to be distributed to
them pursuant to the Agreement following the earlier of (i) the final payment
(or any advance with respect thereto) on or other liquidation of the last
Mortgage Loan or REO Property remaining in the Trust, and (ii) the purchase by
the Depositor, Lehman Brothers Inc., the Master Servicer, the Special Servicer
or any Controlling Class Certificateholder at a price determined as provided in
the Agreement of all Mortgage Loans and any REO Properties remaining in the
Trust. The Agreement permits, but does not require, the Depositor, Lehman
Brothers Inc., the Master Servicer, the Special Servicer or any Controlling
Class Certificateholder to purchase from the Trust all Mortgage Loans and any
REO Properties remaining therein. The exercise of such right will effect early
retirement of the Certificates; however, such right to purchase is subject to
the aggregate Stated Principal Balance of the Mortgage Pool at the time of
purchase being less than approximately 1.0% of the aggregate Certificate
Principal Balance of all the Principal Balance Certificates as of the Closing
Date. In addition, following the date on which the total principal balance of
the Class A-1, A-2, A-3, A-4, B, C, D, E, F and G Certificates is reduced to
zero, any single Holder or group of Holders of all of the remaining Certificates
may, with the consent of the Master Servicer and subject to such other
conditions as may be set forth in the Agreement, exchange those Certificates for
all Mortgage Loans and REO Properties remaining in the Trust Fund at the time of
the exchange.

                                     A-6-6
<PAGE>

         The Agreement permits, with certain exceptions therein provided, the
amendment thereof, and the modification of the rights and obligations of the
Depositor, the Master Servicer, the Special Servicer, the Trustee and the Fiscal
Agent thereunder and the rights of the Certificateholders thereunder, at any
time by the Depositor, the Master Servicer, the Special Servicer, the Trustee
and the Fiscal Agent with the consent of the Holders of Certificates entitled to
at least 66-2/3% of the Voting Rights allocated to the affected Classes. Any
such consent by the Holder of this Certificate shall be conclusive and binding
on such Holder and upon all future Holders of this Certificate and of any
Certificate issued upon the transfer hereof or in exchange herefor or in lieu
hereof whether or not notation of such consent is made upon this Certificate.
The Agreement also permits the amendment thereof, in certain circumstances,
including any amendment necessary to maintain the status of any REMIC Pool as a
REMIC, without the consent of the Holders of any of the Certificates.

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

         The registered Holder hereof, by its acceptance hereof, agrees that it
will look solely to the Trust (to the extent of its rights therein) for
distributions hereunder.

         This Certificate shall be construed in accordance with the internal
laws of the State of New York applicable to agreements made and to be performed
in said State, without applying any conflicts of law principles of such state
(other than the provisions of Section 5-1401 of the New York General Obligations
Law), and the obligations, rights and remedies of the Holder hereof shall be
determined in accordance with such laws.

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

Ladies and Gentlemen:

         Pursuant to Section 2.02(b) of the Pooling and Servicing Agreement
dated as of January 12, 2004, relating to the above-referenced Certificates (the
"Agreement"), LaSalle Bank National Association, in its capacity as trustee (the
"Trustee"), hereby certifies as to each Mortgage Loan subject as of the date
hereof to the Agreement (except as identified in the exception report attached
hereto) that: (i) all documents specified in clauses (a)(i) through (a)(v),
(a)(vii), (a)(viii) and (a)(ix) of the definition of "Mortgage File" (without
regard to the second parenthetical in such clause (a)(viii)), are in its
possession or the possession of a Custodian on its behalf; (ii) the
recordation/filing contemplated by Section 2.01(c) of the Agreement has been
completed (based solely on receipt by the Trustee of the particular
recorded/filed documents); (iii) all documents received by it or any Custodian
with respect to such Mortgage Loan have been reviewed by it or by such Custodian
on its behalf and (A) appear regular on their face (handwritten additions,
changes or corrections shall not constitute irregularities if initialed by the
Mortgagor), (B) appear to have been executed (where appropriate) and (C) purport
to relate to such Mortgage Loan; and (iv) based on the examinations referred to
in Section 2.02(a) of the Agreement and in this Certification and only as to the
foregoing documents, the information set forth in the Trust Mortgage Loan
Schedule with respect to the items specified in clauses (v) and (vi)(B) of the
definition of "Trust Mortgage Loan Schedule" accurately reflects the information
set forth in the Mortgage File.

         Neither the Trustee nor any Custodian is under any duty or obligation
to inspect, review or examine any of the documents, instruments, certificates or
other papers relating to the Mortgage Loans delivered to it to determine that
the same are valid, legal, effective, genuine, binding, enforceable, sufficient
or appropriate for the represented purpose or that they are other than what they
purport to be on their face. Furthermore, neither the Trustee nor any Custodian
shall have any responsibility for determining whether the text of any assignment
or endorsement is in proper or recordable form, whether the requisite recording
of any document is in accordance with the requirements of any applicable
jurisdiction, or whether a blanket assignment is permitted in any applicable
jurisdiction. In performing the review contemplated herein, the Trustee or any
Custodian may rely on the Depositor as to the purported genuineness of any such
document and any signature thereon.

The Transferor hereby certifies, represents and warrants to you, as Certificate

           _____________________________________________________________________
           _____________________________________________________________________

        3. For purposes of determining the aggregate amount of securities
    owned and/or invested on a discretionary basis by any Person, the Transferee
    did not include (i) securities of issuers that are affiliated with such

    subscription by such Person, if such Person is a dealer, (iii) bank deposit
    notes and certificates of deposit, (iv) loan participations, (v) repurchase

        4. For purposes of determining the aggregate amount of securities owned

    securities holdings in its financial statements on the basis of their market
    value, and no current information with respect to the cost of those
    securities has been published, in which case the securities were valued at
    market. Further, in determining

                                     F-2A-4
<PAGE>

    such aggregate amount, the Transferee may have included securities owned by
    subsidiaries of such Person, but only if such subsidiaries are consolidated
    with such Person in its financial statements prepared in accordance with
    generally accepted accounting principles and if the investments of such
    subsidiaries are managed under such Person's direction. However, such
    securities were not included if such Person is a majority-owned,
    consolidated subsidiary of another enterprise and such Person is not itself
    a reporting company under the Securities Exchange Act of 1934, as amended.

        5. The Transferee is familiar with Rule 144A and understands that the
    Transferor and other parties related to the Transferred Certificates are
    relying and will continue to rely on the statements made herein because one
    or more sales to the Transferee may be in reliance on Rule 144A.

        ___     ___    Will the Transferee be purchasing the Transferred
        Yes     No     Certificates only for the Transferee's own account?

        6. If the answer to the foregoing question is "no", then in each case
    where the Transferee is purchasing for an account other than its own, such
    account belongs to a third party that is itself a "qualified institutional
    buyer" within the meaning of Rule 144A, and the "qualified institutional
    buyer" status of such third party has been established by the Transferee
    through one or more of the appropriate methods contemplated by Rule 144A.

        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
    Transferred Certificates will constitute a reaffirmation of this
    certification as of the date of such purchase. In addition, if the
    Transferee is a bank or savings and loan as provided above, the Transferee
    agrees that it will furnish to such parties any updated annual financial
    statements that become available on or before the date of such purchase,
    promptly after they become available.

        8. Capitalized terms used but not defined herein have the respective
    meanings ascribed thereto in the Pooling and Servicing Agreement pursuant to

            QUALIFIED INSTITUTIONAL BUYER STATUS UNDER SEC RULE 144A
           [FOR TRANSFEREES THAT ARE REGISTERED INVESTMENT COMPANIES]

             The undersigned hereby certifies as follows to [name of Transferor]
(the "Transferor") and [name of Certificate Registrar], as Certificate
Registrar, with respect to the mortgage pass-through certificates (the
"Transferred Certificates") described in the Transferee Certificate to which
this certification relates and to which this certification is an Annex:

             1. As indicated below, the undersigned is the chief financial
    officer, a person fulfilling an equivalent function, or other executive
    officer of the entity purchasing the Transferred Certificates (the
    "Transferee") or, if the Transferee is a "qualified institutional buyer" as
    that term is defined in Rule 144A ("Rule 144A") under the Securities Act of
    1933, as amended, because the Transferee is part of a Family of Investment
    Companies (as defined below), is an executive officer of the investment
    adviser (the "Adviser").

             2. The Transferee is a "qualified institutional buyer" as defined
    in Rule 144A because (i) the Transferee is an investment company registered
    under the Investment Company Act of 1940, and (ii) as marked below, the
    Transferee alone owned and/or invested on a discretionary basis, or the
    Transferee's Family of Investment Companies owned, at least $100,000,000 in
    securities (other than the excluded securities referred to below) as of the
    end of the Transferee's most recent fiscal year. For purposes of determining
    the amount of securities owned by the Transferee or the Transferee's Family
    of Investment Companies, the cost of such securities was used, unless the
    Transferee or any member of the Transferee's Family of Investment Companies,
    as the case may be, reports its securities holdings in its financial
    statements on the basis of their market value, and no current information
    with respect to the cost of those securities has been published, in which
    case the securities of such entity were valued at market.

    ______     The Transferee owned and/or invested on a discretionary basis
               $___________________ in securities (other than the excluded
               securities referred to below) as of the end of the Transferee's
               most recent fiscal year (such amount being calculated in
               accordance with Rule 144A).

    ______     The Transferee is part of a Family of Investment Companies which
               owned in the aggregate $______________ in securities (other than
               the excluded securities referred to below) as of the end of the
               Transferee's most recent fiscal year (such amount being
               calculated in accordance with Rule 144A).

             3. The term "Family of Investment Companies" as used herein means
    two or more registered investment companies (or series thereof) that have
    the same investment adviser or investment advisers that are affiliated (by
    virtue of being majority owned subsidiaries of the same parent or because
    one investment adviser is a majority owned subsidiary of the other).

             4. The term "securities" as used herein does not include (i)
    securities of issuers that are affiliated with the Transferee or are part of
    the Transferee's Family of Investment Companies,

                                     F-2A-6
<PAGE>

    (ii) bank deposit notes and certificates of deposit, (iii) loan
    participations, (iv) repurchase agreements, (v) securities owned but subject
    to a repurchase agreement and (vi) currency, interest rate and commodity
    swaps. For purposes of determining the aggregate amount of securities owned
    and/or invested on a discretionary basis by the Transferee, or owned by the
    Transferee's Family of Investment Companies, the securities referred to in
    this paragraph were excluded.

             5. The Transferee is familiar with Rule 144A and understands that
    the Transferor and other parties related to the Transferred Certificates are
    relying and will continue to rely on the statements made herein because one
    or more sales to the Transferee will be in reliance on Rule 144A.

             _____   _____   Will the Transferee be purchasing the Transferred
              Yes     No     Certificates only for the Transferee's own account?

             6. If the answer to the foregoing question is "no", then in each
    case where the Transferee is purchasing for an account other than its own,
    such account belongs to a third party that is itself a "qualified
    institutional buyer" within the meaning of Rule 144A, and the "qualified
    institutional buyer" status of such third party has been established by the
    Transferee through one or more of the appropriate methods contemplated by
    Rule 144A.

             7. The undersigned will notify the parties to which this
    certification is made of any changes in the information and conclusions
    herein. Until such notice, the Transferee's purchase of the Transferred
    Certificates will constitute a reaffirmation of this certification by the
    undersigned as of the date of such purchase.

    respective meanings ascribed thereto in the Pooling and Servicing Agreement
    pursuant to which the Transferred Certificates were issued.

Ladies and Gentlemen:

             This letter is delivered to you in connection with the transfer by
_________________________ (the "Transferor") to __________________________ (the
"Transferee") of the captioned Certificates (the "Transferred Certificates"),
pursuant to Section 5.02 of the Pooling and Servicing Agreement (the "Pooling

Asset Securities Corporation II, as Depositor, Wachovia Bank, National
Association, as Master Servicer, Lennar Partners, Inc., as Special Servicer,
LaSalle Bank National Association, as Trustee, and ABN AMRO Bank N.V., as Fiscal
Agent. All capitalized terms used herein and not otherwise defined shall have
the respective meanings set forth in the Pooling and Servicing Agreement. The
Transferee hereby certifies, represents and warrants to you, as Certificate
Registrar, and for the benefit of the Trustee and the Depositor, that:

             1. The Transferee is acquiring the Transferred Certificates for its
      own account for investment and not with a view to or for sale or transfer
      in connection with any distribution thereof, in whole or in part, in any
      manner which would violate the Securities Act of 1933, as amended (the
      "Securities Act"), or any applicable state securities laws.

             2. The Transferee understands that (a) the Transferred Certificates
      have not been and will not be registered under the Securities Act or
      registered or qualified under any applicable state securities laws, (b)
      none of the Depositor, the Trustee or the Certificate Registrar is
      obligated so to register or qualify the Class of Certificates to which the
      Transferred Certificates belong, and (c) neither a Transferred Certificate
      nor any security issued in exchange therefor or in lieu thereof may be
      resold or transferred unless it is (i) registered pursuant to the
      Securities Act and registered or qualified pursuant to any applicable
      state securities laws or (ii) sold or transferred in transactions which
      are exempt from such registration and qualification and the Certificate
      Registrar has received: (A) a certification from the Certificateholder
      desiring to effect such transfer substantially in the form attached as
      Exhibit F-1 to the Pooling and Servicing

                                     F-2B-1
<PAGE>

      Agreement and a certification from such Certificateholder's prospective
      transferee substantially in the form attached either as Exhibit F-2A to
      the Pooling and Servicing Agreement or as Exhibit F-2B to the Pooling and
      Servicing Agreement; or (B) an opinion of counsel satisfactory to the
      Trustee with respect to, among other things, the availability of such
      exemption from registration under the Securities Act, together with copies
      of the written certification(s) from the transferor and/or transferee
      setting forth the facts surrounding the transfer upon which such opinion
      is based.

             3. The Transferee understands that it may not sell or otherwise
      transfer any Transferred Certificate or interest therein, except in
      compliance with the provisions of Section 5.02 of the Pooling and
      Servicing Agreement, which provisions it has carefully reviewed, and that
      each Transferred Certificate will bear the following legends:

             THIS CERTIFICATE HAS NOT BEEN REGISTERED OR QUALIFIED UNDER THE
             SECURITIES ACT OF 1933, AS AMENDED (THE "SECURITIES ACT") OR THE
             SECURITIES LAWS OF ANY STATE. ANY RESALE, PLEDGE, TRANSFER OR OTHER
             DISPOSITION OF THIS CERTIFICATE OR ANY INTEREST HEREIN WITHOUT SUCH
             REGISTRATION OR QUALIFICATION MAY BE MADE ONLY IN A TRANSACTION
             WHICH DOES NOT REQUIRE SUCH REGISTRATION OR QUALIFICATION AND WHICH
             IS IN ACCORDANCE WITH THE PROVISIONS OF SECTION 5.02 OF THE POOLING
             AND SERVICING AGREEMENT REFERRED TO HEREIN.

             NO TRANSFER OF THIS CERTIFICATE OR ANY INTEREST HEREIN MAY BE MADE
             TO (A) ANY RETIREMENT PLAN OR OTHER EMPLOYEE BENEFIT PLAN OR
             ARRANGEMENT THAT IS SUBJECT TO THE EMPLOYEE RETIREMENT INCOME
             SECURITY ACT OF 1974, AS AMENDED ("ERISA"), OR SECTION 4975 OF THE
             INTERNAL REVENUE CODE OF 1986, AS AMENDED (THE "CODE"), OR (B) ANY
             PERSON WHO IS DIRECTLY OR INDIRECTLY PURCHASING THIS CERTIFICATE OR
             SUCH INTEREST HEREIN ON BEHALF OF, AS NAMED FIDUCIARY OF, AS
             TRUSTEE OF, OR WITH ASSETS OF ANY SUCH RETIREMENT PLAN OR OTHER
             EMPLOYEE BENEFIT PLAN OR ARRANGEMENT, EXCEPT IN ACCORDANCE WITH THE
             PROVISIONS OF SECTION 5.02 OF THE POOLING AND SERVICING AGREEMENT
             REFERRED TO HEREIN.

             4. Neither the Transferee nor anyone acting on its behalf has (a)
      offered, pledged, sold, disposed of or otherwise transferred any
      Transferred Certificate, any interest in any Transferred Certificate or
      any other similar security to any person in any manner, (b) solicited any
      offer to buy or accept a pledge, disposition or other transfer of any
      Transferred Certificate, any interest in any Transferred Certificate or
      any other similar security from any person in any manner, (c) otherwise
      approached or negotiated with respect to any Transferred Certificate, any
      interest in any Transferred Certificate or any other similar security with
      any person in any manner, (d) made any general solicitation with respect
      to any Transferred Certificate, any

                                     F-2B-2
<PAGE>

      interest in any Transferred Certificate or any other similar security by
      means of general advertising or in any other manner, or (e) taken any
      other action with respect to any Transferred Certificate, any interest in
      any Transferred Certificate or any other similar security, which (in the
      case of any of the acts described in clauses (a) through (e) above) would
      constitute a distribution of the Transferred Certificates under the
      Securities Act, would render the disposition of the Transferred
      Certificates a violation of Section 5 of the Securities Act or any state
      securities law or would require registration or qualification of the
      Transferred Certificates pursuant thereto. The Transferee 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 Transferred
      Certificate, any interest in any Transferred Certificate or any other
      similar security.

             5. The Transferee has been furnished with all information regarding
      (a) the Depositor, (b) the Transferred Certificates and distributions
      thereon, (c) the Pooling and Servicing Agreement and the Trust Fund
      created pursuant thereto, (d) the nature, performance and servicing of the
      Mortgage Loans, and (e) all related matters, that it has requested.

             6. The Transferee is an "accredited investor" as defined in any of
      paragraphs (1), (2), (3) and (7) of Rule 501(a) under the Securities Act
      or an entity in which all of the equity owners come within such
      paragraphs. The Transferee has such knowledge and experience in financial
      and business matters as to be capable of evaluating the merits and risks
      of an investment in the Transferred Certificates; the Transferee has
      sought such accounting, legal and tax advice as it has considered
      necessary to make an informed investment decision; and the Transferee is
      able to bear the economic risks of such investment and can afford a
      complete loss of such investment.

      registered in the name of a nominee, such nominee has completed the
      Nominee Acknowledgement below.

for the benefit of the Depositor, that:

             1. The Transferee is a "qualified institutional buyer" (a
      "Qualified Institutional Buyer") as that term is defined in Rule 144A
      ("Rule 144A") under the Securities Act of 1933, as amended (the

      aware that the Transfer to it of the Transferor's interest in the

      Transferee is acquiring such interest in the Transferred Certificates for
      its own account or for the account of another Qualified Institutional
      Buyer.

             2. The Transferee understands that (a) the Transferred Certificates

      registered or qualified under any applicable state securities laws, (b)
      none of the Depositor, the Trustee or the Certificate Registrar is
      obligated so to register or qualify the Transferred Certificates and (c)
      no interest in the Transferred Certificates may be resold or transferred
      unless (i) such Certificates are registered pursuant to the Securities Act
      and registered or qualified pursuant to any applicable state securities
      laws, or (ii) such interest is sold or transferred in a transaction which
      is exempt from such registration and qualification and the Transferor
      desiring to effect such transfer has received (A) a certificate from such
      Certificate Owner's prospective transferee substantially in the form

      opinion of counsel to the effect that, among other things, such
      prospective transferee is a Qualified Institutional Buyer and such
      transfer may be made without registration under the Securities Act.

             3. The Transferee understands that it may not sell or otherwise
      transfer the Transferred Certificates or any interest therein except in
      compliance with the provisions of Section 5.02 of the Pooling and
      Servicing Agreement, which provisions it has carefully reviewed, and that
      the Transferred Certificates will bear the following legends:

      ___    ERISA Plan. The Transferee is an employee benefit plan within the

             cross-reference to the paragraph and subparagraph under subsection
             (a)(1) of Rule 144A pursuant to which it qualifies. Note that
             registered investment companies should complete Annex 2 rather than
             this Annex 1.)

             3. For purposes of determining the aggregate amount of securities
owned and/or invested on a discretionary basis by any Person, the Transferee did
not include (i) securities of issuers that are affiliated with such Person, (ii)
securities that are part of an unsold allotment to or subscription by such
Person, if such Person is a dealer, (iii) bank deposit notes and certificates of
deposit, (iv) loan participations, (v) repurchase agreements, (vi) securities
owned but subject to a repurchase agreement and (vii) currency, interest rate
and commodity swaps.

             4. For purposes of determining the aggregate amount of securities
owned and/or invested on a discretionary basis by any Person, the Transferee
used the cost of such securities to such Person, unless such Person reports its
securities holdings in its financial statements on the basis of their market
value, and no current information with respect to the cost of those securities
has been published, in which case the securities were valued at market. Further,
in determining such aggregate amount, the Transferee may have included
securities owned by subsidiaries of such Person, but only if such subsidiaries
are consolidated with such Person in its financial

                                     F-2C-5
<PAGE>

statements prepared in accordance with generally accepted accounting principles
and if the investments of such subsidiaries are managed under such Person's
direction. However, such securities were not included if such Person is a
majority-owned, consolidated subsidiary of another enterprise and such Person is
not itself a reporting company under the Securities Exchange Act of 1934, as
amended.

             5. The Transferee acknowledges that it is familiar with Rule 144A
and understands that the Transferor and other parties related to the Transferred
Certificates are relying and will continue to rely on the statements made herein
because one or more Transfers to the Transferee may be in reliance on Rule 144A.

             _____   ____    Will the Transferee be purchasing the Transferred
              Yes     No     Certificates only for the Transferee's own account?

             6. If the answer to the foregoing question is "no," then in each
case where the Transferee is acquiring any interest in the Transferred
Certificates for an account other than its own, such account belongs to a third
party that is itself a "qualified institutional buyer" within the meaning of
Rule 144A, and the "qualified institutional buyer" status of such third party
has been established by the Transferee through one or more of the appropriate
methods contemplated by Rule 144A.

             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 acquisition of any interest in any
of the Transferred Certificates will constitute a reaffirmation of this
certification as of the date of such acquisition. In addition, if the Transferee
is a bank or savings and loan as provided above, the Transferee agrees that it
will furnish to such parties any updated annual financial statements that become
available on or before the date of such acquisition, promptly after they become
available.

             8. Capitalized terms used but not defined herein have the meanings
ascribed thereto in the Pooling and Servicing Agreement pursuant to which the
Transferred Certificates were issued.

            QUALIFIED INSTITUTIONAL BUYER STATUS UNDER SEC RULE 144A
           [FOR TRANSFEREES THAT ARE REGISTERED INVESTMENT COMPANIES]

             The undersigned hereby certifies as follows to [name of Transferor]
(the "Transferor") and for the benefit of Structured Asset Securities
Corporation II with respect to the mortgage pass-through certificates being
transferred in book-entry form (the "Transferred Certificates") as described in
the Transferee certificate to which this certification relates and to which this
certification is an Annex:

             1. As indicated below, the undersigned is the chief financial
      officer, a person fulfilling an equivalent function, or other executive
      officer of the entity acquired interests the Transferred Certificates (the
      "Transferee") or, if the Transferee is a "qualified institutional buyer"
      as that term is defined in Rule 144A under the Securities Act of 1933, as
      amended ("Rule 144A"), because the Transferee is part of a Family of
      Investment Companies (as defined below), is an executive officer of the
      investment adviser (the "Adviser").

             2. The Transferee is a "qualified institutional buyer" as defined
      in Rule 144A because (i) the Transferee is an investment company
      registered under the Investment Company Act of 1940, as amended, and (ii)
      as marked below, the Transferee alone owned and/or invested on a
      discretionary basis, or the Transferee's Family of Investment Companies
      owned, at least [$100,000,000] in securities (other than the excluded
      securities referred to below) as of the end of the Transferee's most
      recent fiscal year. For purposes of determining the amount of securities
      owned by the Transferee or the Transferee's Family of Investment
      Companies, the cost of such securities was used, unless the Transferee or
      any member of the Transferee's Family of Investment Companies, as the case
      may be, reports its securities holdings in its financial statements on the
      basis of their market value, and no current information with respect to
      the cost of those securities has been published, in which case the
      securities of such entity were valued at market.

             ____  The Transferee owned and/or invested on a discretionary basis
                   $___________________ in securities (other than the excluded
                   securities referred to below) as of the end of the
                   Transferee's most recent fiscal year (such amount being
                   calculated in accordance with Rule 144A).

             ____  The Transferee is part of a Family of Investment Companies
                   which owned in the aggregate $______________ in securities
                   (other than the excluded securities referred to below) as of
                   the end of the Transferee's most recent fiscal year (such
                   amount being calculated in accordance with Rule 144A).

             3. The term "Family of Investment Companies" as used herein means
      two or more registered investment companies (or series thereof) that have
      the same investment adviser or investment advisers that are affiliated (by
      virtue of being majority owned subsidiaries of the same parent or because
      one investment adviser is a majority owned subsidiary of the other).

                                     F-2C-7

             4. The term "securities" as used herein does not include (i)
      securities of issuers that are affiliated with the Transferee or are part
      of the Transferee's Family of Investment Companies, (ii) bank deposit
      notes and certificates of deposit, (iii) loan participations, (iv)
      repurchase agreements, (v) securities owned but subject to a repurchase
      agreement and (vi) currency, interest rate and commodity swaps. For
      purposes of determining the aggregate amount of securities owned and/or
      invested on a discretionary basis by the Transferee, or owned by the
      Transferee's Family of Investment Companies, the securities referred to in
      this paragraph were excluded.

             5. The Transferee is familiar with Rule 144A and understands that
      the Transferor and other parties related to the Transferred Certificates
      are relying and will continue to rely on the statements made herein
      because one or more Transfers to the Transferee will be in reliance on
      Rule 144A.

             _____   ____   Will the Transferee be purchasing the Transferred
              Yes     No    Certificates only for the Transferee's own account?

             6. If the answer to the foregoing question is "no," then in each
      case where the Transferee is acquiring any interest in the Transferred
      Certificates for an account other than its own, such account belongs to a
      third party that is itself a "qualified institutional buyer" within the
      meaning of Rule 144A, and the "qualified institutional buyer" status of
      such third party has been established by the Transferee through one or
      more of the appropriate methods contemplated by Rule 144A.

             7. The undersigned will notify the parties to which this
      certification is made of any changes in the information and conclusions
      herein. Until such notice, the Transferee's acquisition of any interest in
      the Transferred Certificates will constitute a reaffirmation of this
      certification by the undersigned as of the date of such acquisition.

             5. The Purchaser acknowledges that Section 860E(e) of the Code
would impose a substantial tax on the transferor or, in certain circumstances,
on an agent for the transferee, with respect to any transfer of any interest in
any [Class R-I] [Class R-II] [Class R-III] Certificates to a Disqualified
Organization.

             6. No purpose of the acquisition of the [Class R-I] [Class R-II]

             7. [Check the statement that applies]

     o       If the Transferor requires the safe harbor under Treasury
             regulations section 1.860E-1 to apply:

             a) In accordance with Treasury regulations section 1.860E-1, the
     Purchaser (i) is an "eligible corporation" as defined in Section
     1.860E-1(c)(6)(i) of the Treasury regulations, as to which the income of
     [Class R-I] [Class R-II] [Class R-III] Certificates will only be subject to
     taxation in the United States, (ii) has, and has had in each of its two
     preceding fiscal years, gross assets for financial reporting purposes

     another corporation meeting the criteria set forth in Treasury regulations
     section 1.860E-1; |_|

             or

             b) The Purchaser is a United States Tax Person and the
     consideration paid to the Purchaser for accepting the [Class R-I] [Class
     R-II] [Class R-III] Certificates is greater than the present value of the
     anticipated net federal income taxes and tax benefits ("Tax Liability
     Present Value") associated with owning such Certificates, with such present
     value computed using a discount rate equal to the "Federal short-term rate"
     prescribed by Section 1274 of the Code as of the date hereof or, to the
     extent it is not, if the Transferee has asserted that it regularly borrows,
     in the ordinary course of its trade or business, substantial funds from
     unrelated third parties at a lower interest rate than such applicable
     federal rate and the consideration paid to the Purchaser is greater than
     the Tax Liability Present Value using such lower interest rate as the
     discount rate, the transactions with the unrelated third party lenders, the
     interest rate or rates, the date or dates

                                     H-1-2
<PAGE>

     of such transactions, and the maturity dates or, in the case of adjustable
     rate debt instruments, the relevant adjustment dates or periods, with
     respect to such borrowings, are accurately stated in Exhibit A to this
     letter|_|

     o       If the Transferor does not require the safe harbor under Treasury
             regulations section 1.860E-1 to apply:

             a) The Purchaser is a "United States person" as defined in Section
     7701(a) of the Code and the regulations promulgated thereunder (the
     Purchaser's U.S. taxpayer identification number is __________). The
     Purchaser is not classified as a partnership under the Code (or, if so
     classified, all of its beneficial owners are United States persons); |_|

             or

             b) The Purchaser is not a United States person. However, the
     Purchaser:

                (a) conducts a trade or business within the United States and,
             for purposes of Treasury regulations section 1.860G-3(a)(3), is
             subject to tax under Section 882 of the Code;

                (b) understands that, for purposes of Treasury regulations
             section 1.860E-1(c)(4)(ii), as a holder of a [Class R-I] [Class
             R-II] [Class R-III] Certificate for United States federal income
             tax purposes, it may incur tax liabilities in excess of any cash
             flows generated by such [Class R-I] [Class R-II] [Class R-III]
             Certificate;

                (c) intends to pay the taxes associated with holding a [Class
             R-I] [Class R-II] [Class R-III] Certificate;

                (d) is not classified as a partnership under the Code (or, if so
             classified, all of its beneficial owners either satisfy clauses
             (a), (b) and (c) of this sentence or are United States persons);
             and

                (e) has furnished the Transferor and the Trustee with an
             effective IRS Form W-8ECI or successor form and will update such
             form as may be required under the applicable Treasury regulations
             |_|

                8. The Purchaser historically has paid its debts as they have
     come due and intends to pay its debts as they come due in the future and
     the Purchaser intends to pay taxes associated with holding the [Class R-I]
     [Class R-II] [Class R-III] Certificates as they become due.

                9. The Purchaser understands that it may incur tax liabilities
     with respect to the [Class R-I] [Class R-II] [Class R-III] Certificates in
     excess of any cash flows generated by such Certificates.

                10. The Purchaser will not transfer the [Class R-I] [Class R-II]
     [Class R-III] Certificates to any person or entity as to which the
     Purchaser has not received an affidavit substantially in the form of this
     affidavit or to any person or entity as to which the Purchaser has

                                     H-1-3
<PAGE>

     actual knowledge that the requirements set forth in paragraphs 2, 3, 4, 6
     or 8 hereof are not satisfied, or to any person or entity with respect to
     which the Purchaser has not (at the time of such transfer) satisfied the
     requirements under the Code to conduct a reasonable investigation of the
     financial condition of such person or entity (or its current beneficial
     owners if such person or entity is classified as a partnership under the
     Code).

                11. The Purchaser agrees to such amendments of the Pooling and
     Servicing Agreement as may be required to further effectuate the
     prohibition against transferring the [Class R-I] [Class R-II] [Class R-III]
     Certificates to a Disqualified Organization, an agent thereof or a person
     that does not satisfy the requirements of paragraphs 6 and 8.

                12. The Purchaser consents to the designation of the Trustee as
     the agent of the Tax Matters Person of [REMIC I] [REMIC II] [REMIC III]
     pursuant to Section 10.01(d) of the Pooling and Servicing Agreement.

             Capitalized terms used but not defined herein have the meanings
assigned thereto in the Pooling and Servicing Agreement.

             IN WITNESS WHEREOF, the Purchaser has caused this instrument to be
duly executed on its behalf by its duly authorized officer this ___ day of
__________________.

Ladies and Gentlemen:

             This letter is delivered to you in connection with the transfer by
_________________ (the "Transferor") to _________________ (the "Transferee") of
[Class R-I] [Class R-II] [Class R-III] Certificates evidencing a ____%
Percentage Interest in such Class (the "Residual Interest Certificates"). The
Certificates, including the Residual Interest Certificates, were issued pursuant
to the Pooling and Servicing Agreement, dated as of January 12, 2004 (the
"Pooling and Servicing Agreement"), between Structured Asset Securities
Corporation II, as depositor, Wachovia Bank, National Association, as master
servicer, Lennar Partners, Inc., as special servicer, LaSalle Bank National
Association, as trustee, and ABN AMRO Bank N.V., as fiscal agent. All
capitalized terms used but not otherwise defined herein shall have the
respective meanings set forth in the Pooling and Servicing Agreement. The
Transferor hereby certifies, represents and warrants to you, as Certificate
Registrar, that:

                 1. No purpose of the Transferor relating to the transfer of the
     Residual Interest Certificates by the Transferor to the Transferee is or
     will be to impede the assessment or collection of any tax.

                 2. The Transferor understands that the Transferee has delivered
     to you a Transfer Affidavit and Agreement in the form attached to the
     Pooling and Servicing Agreement as Exhibit H-1. The Transferor does not
     know or believe that any representation contained therein is false.

                 3. The Transferor has at the time of this transfer conducted a
     reasonable investigation of the financial condition of the Transferee (or
     the beneficial owners of the Transferee if it is classified as a
     partnership under the Internal Revenue Code of 1986, as amended) as
     contemplated by Treasury regulations section 1.860E-1(c)(4)(i) and, as a
     result of that investigation, the Transferor has determined that the
     Transferee has historically paid its debts as they became due and has found
     no significant evidence to indicate that the Transferee will not continue
     to pay its debts as they become due in the future. The Transferor
     understands that the transfer of the Residual Interest Certificates may not
     be respected for United States

                                     H-2-1

     income tax purposes (and the Transferor may continue to be liable for
     United States income taxes associated therewith) unless the Transferor has
     conducted such an investigation.

heretofore secured by the Mortgaged [Property] [Properties] identified on the
Trust Mortgage Loan Schedule by the following name[s]:

Reference is made to the Pooling and Servicing Agreement described above.
Capitalized terms used but not defined herein have the meanings assigned to such
terms in the Pooling and Servicing Agreement.

As Master Servicer under the Pooling and Servicing Agreement, we hereby:

             1. Notify you that the Mortgagor has consummated a defeasance of
the Mortgage Loan pursuant to the terms of the Mortgage Loan, of the type
checked below:

             ____  a full defeasance of the payments scheduled to be due in
                   respect of the entire unpaid principal balance of the
                   Mortgage Loan; or

             ____  a partial defeasance of the payments scheduled to be due in
                   respect of a portion of the unpaid principal balance of the
                   Mortgage Loan that represents ___% of

                                      M-2
<PAGE>

                   the entire unpaid principal balance of the Mortgage Loan and,
                   under the Mortgage, has an allocated loan amount of
                   $____________ or _______% of the entire unpaid principal
                   balance;

             2. Certify as to each of the following, and any additional
explanatory notes set forth on Exhibit A hereto:

                a. The Mortgage Loan documents permit the defeasance, and the
     terms and conditions for defeasance specified therein were satisfied in all
     material respects in completing the defeasance.

                b. The defeasance was consummated on __________, 20__.

                c. The defeasance collateral consists of securities that (i)
     constitute "government securities" as defined in Section 2(a)(16) of the
     Investment Company Act of 1940 as amended (15 U.S.C. 80a-1), (ii) are
     listed as "Qualified Investments for `AAA' Financings" under Paragraphs 1,
     2 or 3 of "Cash Flow Approach" in Standard & Poor's Public Finance Criteria
     2000, as amended to the date of the defeasance, (iii) are rated `AAA' by
     Standard & Poor's, (iv) if they include a principal obligation, provide for
     a predetermined fixed dollar amount of principal due at maturity that
     cannot vary or change, and (v) are not subject to prepayment, call or early
     redemption. Such securities have the characteristics set forth below:

         CUSIP         RATE         MAT        PAY DATES         ISSUED
         -----         ----         ---        ---------         ------

                d. The Master Servicer received an opinion of counsel (from
     counsel approved by Master Servicer in accordance with the Servicing
     Standard) that the defeasance will not result in an Adverse REMIC Event.

                e. The Master Servicer determined that the defeasance collateral
     will be owned by an entity (the "Defeasance Obligor") as to which one of
     the statements checked below is true:

             ____  the related Mortgagor was a Single-Purpose Entity (as defined
                   in Standard & Poor's Structured Finance Ratings Real Estate
                   Finance Criteria, as amended to the date of the defeasance
                   (the "S&P Criteria")) as of the date of the defeasance, and
                   after the defeasance owns no assets other than the defeasance
                   collateral and real property securing Mortgage Loan included
                   in the pool.

             ____  the related Mortgagor designated a Single-Purpose Entity (as
                   defined in the S&P Criteria) to own the defeasance
                   collateral; or

             ____  the Master Servicer designated a Single-Purpose Entity (as
                   defined in the S&P Criteria) established for the benefit of
                   the Trust to own the defeasance collateral.

                f. The Master Servicer received a broker or similar confirmation
      of the credit, or the accountant's letter described below contained
      statements that it reviewed a broker or similar confirmation of the
      credit, of the defeasance collateral to an Eligible Account (as

                                      M-3
<PAGE>

      defined in the S&P Criteria) in the name of the Defeasance Obligor, which
      account is maintained as a securities account by the Trustee acting as a
      securities intermediary.

                g. As securities intermediary, the Trustee is obligated to make
      the scheduled payments on the Mortgage Loan from the proceeds of the
      defeasance collateral directly to the Master Servicer's collection account
      in the amounts and on the dates specified in the Mortgage Loan documents
      or, in a partial defeasance, the portion of such scheduled payments
      attributed to the allocated loan amount for the real property defeased,
      increased by any defeasance premium specified in the Mortgage Loan
      documents (the "Scheduled Payments").

                h. The Master Servicer received from the Mortgagor written
      confirmation from a firm of independent certified public accountants, who
      were approved by the Master Servicer in accordance with the Servicing
      Standard, stating that (i) revenues from principal and interest payments
      made on the defeasance collateral (without taking into account any
      earnings on reinvestment of such revenues) will be sufficient to timely
      pay each of the Scheduled Payments after the defeasance including the
      payment in full of the Mortgage Loan (or the allocated portion thereof in
      connection with a partial defeasance) on its Maturity Date (or, in the
      case of an ARD Mortgage Loan, on its Anticipated Repayment Date or on the
      date when any open prepayment period set forth in the related Mortgage
      Loan documents commences), (ii) the revenues received in any month from
      the defeasance collateral will be applied to make Scheduled Payments

      upon the review required under the Pooling and Servicing Agreement, and
      except as disclosed in the Annual Performance Certification delivered by

      obligations under the Pooling and Servicing Agreement; and

                 5. I have disclosed to the accountants that are to deliver the

      Program for Mortgage Bankers or similar standard as set forth in the
      Pooling and Servicing Agreement.

             The foregoing certifications under clauses 2. and 3. above assume
that the following sections and parts of the Prospectus Supplement did not, as
of the date thereof or as of the Closing Date, contain any untrue statement of a
material fact regarding the Mortgage Loan Seller Matters (as defined below) or
omit to state any material fact regarding the Mortgage Loan Seller Matters

Master Servicer entered into in connection with the issuance of the
Certificates, or upon the performance by any such Sub-Servicer of its
