a national banking association, as trustee (the "Trustee").

      The Depositor is the owner of the Trust Fund that is hereby conveyed to the
Trustee in return for the Certificates. The Trust Fund for federal income tax
purposes will consist of (i) three real estate mortgage investment conduits,
(ii) the right to receive payments distributable to the Class P Certificates
pursuant to Section 4.04(b)(i) hereof, (iii) each Cap Contract and the Cap
Contract Account, (iv) the grantor trusts described in Section 2.07 hereof and
(v) the Supplemental Interest Trust, which in turn will hold the Swap Agreement.
The SWAP REMIC will consist of all of the assets constituting the Trust Fund
(other than the assets described in clauses (ii), (iii), (iv) and (v) above,
other than the SWAP REMIC Regular Interests and other than the Lower Tier REMIC
Regular Interests) and will be evidenced by the SWAP REMIC Regular Interests
(which will be uncertificated and will represent the "regular interests" in the
SWAP REMIC) and the Class SWR Interest as the single "residual interest" in the
SWAP REMIC. The Lower Tier REMIC will consist of SWAP REMIC Regular Interests
and will be evidenced by the Lower Tier REMIC Regular Interests (which will be
uncertificated and will represent the "regular interests" in the Lower Tier
REMIC) and the Class LTR Interest as the single "residual interest" in the Lower
Tier REMIC. The Trustee will hold the Lower Tier REMIC Regular Interests. The
Upper Tier REMIC will consist of the Lower Tier REMIC Regular Interests and will
be evidenced by the REMIC Regular Interests (which will represent the "regular
interests" in the Upper Tier REMIC) and the Residual Interest as the single
"residual interest" in the Upper Tier REMIC. The Class R Certificate will
represent beneficial ownership of the Class SWR Interest, the Class LTR Interest
and the Residual Interest. The "latest possible maturity date" for federal
income tax purposes of all interests created hereby will be the Latest Possible
Maturity Date.

     All covenants and agreements made by the Transferor in the Transfer

(1)   The initial principal balance of each of these Lower Tier REMIC Regular
     Interests shall equal 1/4 of the initial Certificate Principal Balance of
     its Corresponding Certificates.

(2)   The initial principal balance of the Class LTIX Interest shall equal the
     excess of (i) 50% of the aggregate Cut-off Date Principal Balance of the
     Mortgage Loans over (ii) the initial principal balance of the Lower Tier
     REMIC I Marker Interests.

(3)   The initial principal balance of the Class LTII1A Interest shall equal
     0.05% of the excess of (i) the aggregate Cut-off Date Principal Balance of
     the Group One Mortgage Loans over (ii) the aggregate of the initial
     Certificate Principal Balances of Certificate Group One.

(4)   The initial principal balance of the Class LTII1B Interest shall equal
     0.05% of the aggregate Cut-off Date Principal Balance of the Group One
     Mortgage Loans.

(5)   The initial principal balance of the Class LTII2A Interest shall equal
     0.05% of the excess of (i) the aggregate Cut-off Date Principal Balance of
     the Group Two Mortgage Loans over (ii) the aggregate of the initial
     Certificate Principal Balances of Certificate Group Two.

(6)   The initial principal balance of the Class LTII2B Interest shall equal
     0.05% of the aggregate Cut-off Date Principal Balance of the Group Two
     Mortgage Loans.

(8)   For each Distribution Date, the interest rate for each of the Lower Tier
     REMIC Regular Interests (other than the Class LTII1B, the Class LTII2B, the
     Class LTCE and the Class LT-IO Interests) shall be a per annum rate (but
     not less than zero) equal to the product of (i) the weighted average of the
     interest rates on the SWAP REMIC Regular Interests (other than the Class
     SWCE Interest) for such Distribution Date and (ii) a fraction the numerator
     of which is 30 and the denominator of which is the actual number of days in
      the Accrual Period for the LIBOR Certificates, provided however, that for
     any Distribution Date on which the Class LT-IO Interest is entitled to a
     portion of interest accruals on a SWAP REMIC Regular Interest ending with a
     designation "A" as described in footnote 11 below, such weighted average
     shall be computed by first subjecting the rate on such SWAP REMIC Regular
     Interest to a cap equal to Swap LIBOR for such Distribution Date.

(9)   For each Distribution Date, the interest rate for the Class LTII1B Interest
     shall be a per annum rate equal to the product of (i) the weighted average
     of the interest rates on the SWAP REMIC Regular Interests beginning with
     the designation "1" for such Distribution Date and (ii) a fraction the
     numerator of which is 30 and the denominator of which is the actual number
     of days in the Accrual Period for the LIBOR Certificates, provided,
     however, that for any Distribution Date on which the Class LT-IO Interest
     is entitled to a portion of interest accruals on a SWAP REMIC Regular
     Interest ending with a designation "A" as described in footnote 11 below,
     such weighted average shall be computed by first subjecting the rate on
     such SWAP REMIC Regular Interest to a cap equal to Swap LIBOR for such
     Distribution Date.

(10) For each Distribution Date, the interest rate for the Class LTII2B Interest
     shall be a per annum rate equal to the product of (i) the weighted average
     of the interest rates on the SWAP REMIC Regular Interests beginning with
     the designation "2" for such Distribution Date and (ii) a fraction the
     numerator of which is 30 and the denominator of which is the actual number
      of days in the Accrual Period for the LIBOR Certificates, provided,
     however, that for any Distribution Date on which the Class LT-IO Interest
     is entitled to a portion of interest accruals on a SWAP REMIC Regular
     Interest ending with a designation "A" as described in footnote 11 below,
     such weighted average shall be computed by first subjecting the rate on
     such SWAP REMIC Regular Interest to a cap equal to Swap LIBOR for such
     Distribution Date.

(11) The Class LT-IO Interest is an interest-only class that does not have a
     principal balance. For only those Distribution Dates listed in the first
     column of the table below, the Class LT-IO Interest shall be entitled to
     interest accrued on the SWAP REMIC Regular Interest listed in the second
     column below at a per annum rate equal to the excess, if any, of (i) the
     interest rate for such SWAP REMIC Regular Interest for such Distribution
     Date over (ii) Swap LIBOR for such Distribution Date.

effect such consent has been obtained; provided, however, that if any such
Person (including the Depositor) owns 100% of the Percentage Interests evidenced
by a Class of Certificates, such Certificates shall be deemed to be Outstanding
for purposes of any provision hereof that requires the consent of the Holders of
Certificates of a particular Class as a condition to the taking of any action
hereunder. The Trustee is entitled to rely conclusively on a certification of
the Depositor or any Affiliate of the Depositor in determining which
Certificates are registered in the name of an Affiliate of the Depositor.

<PAGE>

If in connection with any Mortgage Loan that is not a Co-op Loan, the Depositor
cannot deliver the Mortgage, Assignments of Mortgage or assumption,
consolidation or modification, as the case may be, with evidence of recording
thereon, if applicable, concurrently with the execution and delivery of this
Agreement solely because of a delay caused by the public recording office where
such Mortgage, Assignments of Mortgage or assumption, consolidation or
modification, as the case may be, has been delivered for recordation, the
Depositor shall deliver or cause to be delivered to the Trustee or the Custodian
written notice stating that such Mortgage or assumption, consolidation or
modification, as the case may be, has been delivered to the appropriate public
recording office for recordation. Thereafter, the Depositor shall deliver or
cause to be delivered to the Trustee or the Custodian such Mortgage, Assignments
of Mortgage or assumption, consolidation or modification, as the case may be,
with evidence of recording indicated thereon, if applicable, upon receipt
thereof from the public recording office. To the extent any required endorsement
is not contained on a Mortgage Note or an Assignment of Mortgage, the Depositor
shall make or cause such endorsement to be made.

     With respect to any Mortgage Loan that is not a Co-op Loan, none of the
Depositor, the Servicer or the Trustee shall be obligated to cause to be
recorded the Assignment of Mortgage referred to in this Section 2.01. With
respect to any Co-op Loan, none of the Depositor, the Servicer or the Trustee
shall be obligated to cause to be filed the Form UCC-3 referred to in this
Section 2.01. In the event that any Assignment of Mortgage referred to in this
Section 2.01 is not recorded or is improperly recorded, the Servicer and the
Trustee shall have no liability for any failure to receive or act on notices
related to such Assignment of Mortgage.

     The ownership of each Mortgage Note, the Mortgage and the contents of the
related Mortgage File is vested in the Trustee on behalf of the
Certificateholders. None of the Depositor, the Servicer or the Trustee shall
take any action inconsistent with such ownership and shall not claim any
ownership interest therein. The Depositor, the Servicer and the Trustee shall
respond to any third party inquiries with respect to ownership of the Mortgage
Loans by stating that such ownership is held by the Trustee on behalf of the
Certificateholders. Mortgage documents relating to the Mortgage Loans not
delivered to the Trustee or the Custodian are and shall be held in trust by the
Servicer, for the benefit of the Trustee as the owner thereof, and the
Servicer's possession of the contents of each Mortgage File so retained is for
the sole purpose of servicing the related Mortgage Loan, and such retention and
possession by the Servicer is in a custodial capacity only. The Depositor agrees
to take no action inconsistent with the Trustee's ownership of the Mortgage
Loans, to indicate promptly to all inquiring parties that the Mortgage Loans
have been sold and to claim no ownership interest in the Mortgage Loans.

     It is the intention of this Agreement that the conveyance of the
Depositor's right, title and interest in and to the Trust Fund pursuant to this
Agreement shall constitute a purchase and sale and not a loan. If a conveyance
of Mortgage Loans from the Sponsor to the Depositor is characterized as a pledge
and not a sale, then the Depositor shall be deemed to have transferred to the
Trustee all of the Depositor's right, title and interest in, to and under the
obligations of the Sponsor deemed to be secured by said pledge; and it is the
intention of this Agreement that the Depositor shall also be deemed to have
granted to the Trustee a first priority security interest in all of the
Depositor's right, title, and interest in, to and under the obligations of the
Sponsor to the Depositor deemed to be secured by said pledge and that the
Trustee shall be deemed to be an independent custodian for purposes of
perfection of the security interest granted to the Depositor. If the conveyance
of the Mortgage Loans from the Depositor to the Trustee is characterized as a
pledge, it is the intention of this Agreement that this Agreement shall
constitute a security agreement under applicable law, and that the Depositor
shall be deemed to have granted to the Trustee a first priority security
interest in all of the Depositor's right, title and interest in, to and under
the Mortgage Loans, all payments of principal of or interest on such Mortgage
Loans, all other rights relating to and payments made in respect of the Trust
Fund, and all proceeds of any thereof. If the trust created by this Agreement
terminates prior to the satisfaction of the claims of any Person in any
Certificates, the security interest


                                       63

<PAGE>

created hereby shall continue in full force and effect and the Trustee shall be
deemed to be the collateral agent for the benefit of such Person.

     In addition to the conveyance made in the first paragraph of this Section
2.01, the Depositor does hereby convey, assign and set over to the Trustee for
the benefit of the Certificateholders its rights and interests under the Sale
Agreement, including the Depositor's right, title and interest in the
representations and warranties contained in the Sale Agreement, the rights in
the Transfer Agreement described therein and the benefit of the repurchase
obligations and the obligation of the Sponsor contained in the Sale Agreement to
take, at the request of the Depositor or the Trustee, all action on its part
which is reasonably necessary to ensure the enforceability of a Mortgage Loan.
The Trustee hereby accepts such assignment, and shall be entitled to exercise
all rights of the Depositor under the Sale Agreement as if, for such purpose, it
were the Depositor. The foregoing sale, transfer, assignment, set-over, deposit
and conveyance does not and is not intended to result in creation or assumption
by the Trustee of any obligation of the Depositor, the Sponsor, or any other
Person in connection with the Mortgage Loans or any other agreement or
instrument relating thereto except as specifically set forth herein.

     SECTION 2.02. Acceptance by the Trustee of the Mortgage Loans.

     Except as set forth in the exception report delivered contemporaneously
herewith (the "Exception Report"), the Trustee acknowledges receipt of the
Mortgage Note for each Mortgage Loan and delivery of a Mortgage File (but does
not acknowledge receipt of all documents required to be included in such
Mortgage File) with respect to each Mortgage Loan and declares that it (or the
Custodian) holds and will hold such documents and any other documents
constituting a part of the Mortgage' Files delivered to it in trust for the use
and benefit of all present and future Certificateholders. The Depositor will
cause the Sponsor to repurchase any Mortgage Loan to which a material exception
was taken in the Exception Report unless such exception is cured to the
satisfaction of the Trustee within 45 Business Days of the Closing Date.

     The Trustee acknowledges receipt of the three Cap Contracts (forms of which
are attached hereto as Exhibits N-1, N-2 and N-3), the Transfer Agreement, the
Bring Down Letter and the Sale Agreement.

     The Trustee acknowledges receipt of the Swap Agreement (a form of which is
attached hereto as Exhibit S) that will be held in the Supplemental Interest
Trust and is hereby instructed to enter into the Swap Agreement, not in its
individual capacity, but solely as Trustee for the Supplemental Interest Trust.

     The Trustee agrees, for the benefit of Certificateholders and the NIMs
Insurer, to review or cause its Custodian to review each Mortgage File delivered
to it within 60 days after the Closing Date to ascertain and to certify, within
70 days of the Closing Date, to the NIMs Insurer, the Depositor and the Servicer
that all documents required by Section 2.01 (provided that with respect to the
items listed in Sections 2.01(i)(F) and 2.01(ii)(E)-(K), to the extent
identified on the Mortgage Loan Schedule) have been executed and received, and
that such documents relate to the Mortgage Loans identified in Exhibit B-1 that
have been conveyed to it. It is herein acknowledged that, in conducting such
review, the Trustee shall not be under any duty or obligation to inspect, review
or examine any such documents, instruments, certificates or other papers to
determine that they are genuine, enforceable or appropriate for the represented
purpose, that they have actually been recorded or that they are other than what
they purport to be on their face. If the Trustee or the Custodian finds any
document or documents constituting a part of a Mortgage File to be missing or
defective (that is, mutilated, damaged, defaced or unexecuted) in any material
respect, the Trustee or the Custodian shall promptly (and in any event within no
more than five Business Days) after such finding so notify the NIMs Insurer, the
Servicer, the Sponsor and the Depositor. In addition, the Trustee or the
Custodian shall also notify the NIMs Insurer, the Servicer, the Sponsor and the
Depositor if the original Mortgage with evidence of recording thereon with
respect to a


                                        64

<PAGE>

Mortgage Loan is not received within 70 days of the Closing Date; if it has not
been received because of a delay caused by the public recording office where
such Mortgage has been delivered for recordation, the Depositor shall deliver or
cause to be delivered to the Trustee written notice stating that such Mortgage
has been delivered to the appropriate public recording office for recordation
and thereafter the Depositor shall deliver or cause to be delivered such
Mortgage with evidence of recording thereon upon receipt thereof from the public
recording office. The Trustee shall request that the Sponsor correct or cure
such omission, defect or other irregularity, or substitute a Mortgage Loan
pursuant to the provisions of Section 2.03, within 90 days from the date the
Sponsor was notified of such omission or defect and, if the Sponsor does not
correct or cure such omission or defect within such period, that the Sponsor
purchase such Mortgage Loan from the Trust Fund within 90 days from the date the
Trustee notified the Sponsor of such omission, defect or other irregularity at
the Purchase Price of such Mortgage Loan.

     The Purchase Price for any Mortgage Loan purchased pursuant to this Section
2.02 shall be paid to the Servicer and deposited by the Servicer in the
Certificate Account or Collection Account, as appropriate, promptly upon
receipt, and, upon receipt by the Trustee of written notification of such
deposit signed by a Servicing Officer, the Trustee, upon receipt of a Request
for Release, shall promptly release to the Sponsor the related Mortgage File and
the Trustee shall execute and deliver such instruments of transfer or
assignment, without recourse, as shall be requested by the Sponsor and necessary
to vest in the Sponsor or its designee, as the case may be, any Mortgage Loan
released pursuant hereto, and the Trustee shall have no further responsibility
with regard to such Mortgage Loan. It is understood and agreed that the
obligation of the Sponsor to purchase, cure or substitute any Mortgage Loan as
to which a material defect in or omission of a constituent document exists shall
constitute the sole remedy respecting such defect or omission available to the
Trustee on behalf of Certificateholders and the NIMs Insurer. The preceding
sentence shall not, however, limit any remedies available to the
Certificateholders, the NIMs Insurer, the Depositor or the Trustee pursuant to
the Sale Agreement, the Transfer Agreement and the Bring Down Letter.

     The Trustee shall be under no duty or obligation to inspect, review and
examine such documents, instruments, certificates or other papers to determine
that they are genuine, enforceable, recordable, duly authorized, sufficient,
legal, valid or appropriate to the represented purpose, or that they have
actually been recorded, or that they are other than what they purport to be on
their face. The Servicer and the Trustee shall keep confidential the name of
each Mortgagor except as required by this Agreement and the Trustee shall not
solicit any such Mortgagor for the purpose of refinancing the related Mortgage
Loan; notwithstanding anything herein to the contrary, the foregoing shall not
be construed to prohibit (i) disclosure of any and all information that is or
becomes publicly known, or information obtained by the Trustee or the Servicer
from sources other than the other parties hereto, (ii) disclosure of any and all
information (A) if required by any applicable law, rule or regulation, (B) to
any government agency or regulatory body having or claiming authority to
regulate or oversee any aspects of the Trustee's business or that of its
affiliates, (C) pursuant to any subpoena, civil investigation demand or similar
demand or request of any court, regulatory authority, arbitrator or arbitration
to which Trustee or any affiliate or an officer, director, employer or
shareholder thereof is a party or (D) to any affiliate, independent or internal
auditor, agent, employee or attorney of the Trustee or the Servicer having a
need to know the same, provided that the Trustee or the Servicer, as applicable,
advises such recipient of the confidential nature of the information being
disclosed, or (iii) any other disclosure authorized by the Depositor. It is
understood and agreed that all rights and benefits relating to the solicitation
of any Mortgagors and the attendant rights, title and interest in and to the
list of Mortgagors and data relating to the Mortgages shall be retained by the
Servicer.

     Within 70 days of the Closing Date, the Trustee or the Custodian shall
deliver to the NIMs Insurer, the Depositor and the Servicer, the Trustee's
Certification, substantially in the form of Exhibit D attached hereto,
evidencing the completeness of the Mortgage Files, with any exceptions noted
thereto.

     SECTION 2.03. Representations, Warranties and Covenants of the Depositor.

     (a) The Depositor hereby represents and warrants to the Servicer, the NIMs
Insurer and the Trustee as follows, as of the date hereof:

          (i) The Depositor is duly organized and is validly existing as a
     corporation in good standing under the laws of the State of Delaware and
     has full power and authority (corporate and other) necessary to own or hold
     its properties and to conduct its business as now conducted by it and to
     enter into and perform its obligations under this Agreement and the Sale
     Agreement.

          (ii) The Depositor has the full corporate power and authority to
     execute, deliver and perform, and to enter into and consummate the
     transactions contemplated by, this Agreement and the Sale Agreement and has
     duly authorized, by all necessary corporate action on its part, the
     execution, delivery and performance of this Agreement and the Sale
     Agreement; and this Agreement and the Sale Agreement, assuming the due
     authorization, execution and delivery hereof by the other parties hereto,
     constitutes a legal, valid and binding obligation of the Depositor,
      enforceable against the Depositor in accordance with its terms, subject, as
     to enforceability, to (i) bankruptcy, insolvency, reorganization,
     moratorium and other similar laws affecting creditors' rights generally and
     (ii) general principles of equity, regardless of whether enforcement is
     sought in a proceeding in equity or at law.

          (iii) The execution and delivery of this Agreement and the Sale
     Agreement by the Depositor, the consummation of the transactions
     contemplated by this Agreement and the Sale Agreement, and the fulfillment
     of or compliance with the terms hereof are in the ordinary course of
     business of the Depositor and will not (A) result in a material breach of
     any term or provision of the charter or by-laws of the Depositor or (B)
     materially conflict with, result in a violation or acceleration of, or
     result in a material default under, the terms of any other material
     agreement or instrument to which the Depositor is a party or by which it
     may be bound or (C) constitute a material violation of any statute, order
     or regulation applicable to the Depositor of any court, regulatory body,
     administrative agency or governmental body having jurisdiction over the
     Depositor; and the Depositor is not in breach or violation of any material
     indenture or other material agreement or instrument, or in violation of any
     statute, order or regulation of any court, regulatory body, administrative
     agency or governmental body having jurisdiction over it which breach or
     violation may materially impair the Depositor's ability to perform or meet
     any of its obligations under this Agreement.

          (iv) No litigation is pending, or, to the best of the Depositor's
     knowledge, threatened, against the Depositor that would materially and
     adversely affect the execution, delivery or enforceability of this
     Agreement and the Sale Agreement or the ability of the Depositor to perform
     its obligations under this Agreement and the Sale Agreement in accordance
     with the terms hereof.

          (v) No consent, approval, authorization or order of any court or
     governmental agency or body is required for the execution, delivery and
     performance by the Depositor of, or compliance by the Depositor with, this
     Agreement and the Sale Agreement or the consummation of the transactions
     contemplated hereby, or if any such consent, approval, authorization or
     order is required, the Depositor has obtained the same. The Depositor
     hereby represents and warrants to the Trustee with respect to each Mortgage
     Loan as of the Closing Date and following the transfer of the Mortgage
     Loans to it by the Sponsor, the Depositor had good title to the Mortgage
     Loans and the Mortgage Notes were subject to no offsets, claims, liens,
     mortgage, pledge, charge, security interest, defenses or counterclaims.


                                       66

<PAGE>

     (b) The representations and warranties of the Transferor with respect to
the Mortgage Loans contained in the Transfer Agreement were made as of the date
of the Transfer Agreement and brought forward to the Closing Date pursuant to
the Bring Down Letter. The representations and warranties of the Transferor with
respect to the Mortgage Loans contained in the Bring Down Letter were made as of
the Closing Date. The representations and warranties of the Sponsor with respect
to the Mortgage Loans contained in the Sale Agreement were made as of the
Closing Date.

     To the extent that any fact, condition or event with respect to a Mortgage
Loan constitutes a breach of a representation or warranty of the Transferor
under the Transfer Agreement (whether or not such fact, condition or event would
also constitute a breach of a representation or warranty of the Sponsor under
the Sale Agreement), the only rights or remedies of the Trustee, the NIMs
Insurer or of any Certificateholder shall be first, the Trustee's right to
enforce the obligations of the Transferor under such applicable representation
or warranty made by it and, second, only if the Transferor is unable or
unwilling to fulfill its obligations to cure or repurchase such Mortgage Loan,
the Trustee shall exercise its right to enforce any rights it may have against
the Sponsor under the Sale Agreement with respect to such representation or
warranty; provided, that in the event the Trustee shall have received a copy of
any Transferor Affirmation Notice, the Trustee shall only be entitled to enforce
any rights it has against the Transferor under the Transfer Agreement and shall
not have any rights against the Sponsor under the Sale Agreement with respect to
such representation or warranty. To the extent that any fact, condition or event
with respect to a Mortgage Loan constitutes a breach of a representation or
warranty made by the Sponsor in the Sale Agreement that does not also constitute
a breach of a representation or warranty of the Transferor under the Transfer
Agreement, the Trustee shall use reasonable efforts to enforce any rights it may
have against the Sponsor under the Sale Agreement. In furtherance of the above,
the Sponsor expressly acknowledges that prior to the issuance of a Transferor
Affirmation Notice, it shall be obligated and liable to the Trustee, the NIMs
Insurer and the Certificateholders for any breach of a representation or
warranty made under the Transfer Agreement, but only after the Transferor
evidences that it is unwilling or unable to fulfill its contractual obligations
under the Transfer Agreement. The Trustee acknowledges that the Depositor shall
have no obligation or liability with respect to any breach of any representation
or warranty with respect to the Mortgage Loans (except as set forth in Section
2.03(a)(v)) under any circumstances.

     In addition to the representations and warranties of the Transferor in the
Transfer Agreement that were brought forward to the Closing Date pursuant to the
Bring Down Letter, with respect to each Mortgage Loan, the Transferor made
certain additional covenants regarding such Mortgage Loan, as set forth in the
Transfer Agreement. With respect to any breach of such additional covenants that
materially and adversely affects the interests of the Certificateholders in such
Mortgage Loan, the Sponsor shall (1) use reasonable efforts to enforce such
covenant against the Transferor and (2) if the Sponsor successfully enforces any
obligation of the Transferor to repurchase such Mortgage Loan, the Sponsor shall
repurchase such Mortgage Loan in accordance with this Section 2.03. If the
Sponsor does not successfully enforce the obligation, if any, of the Transferor
to repurchase a Mortgage Loan with respect to any breach of any such additional
covenants, the Sponsor shall have no obligation or right to repurchase or cure
such Mortgage Loan.

     (c) Upon discovery by any of the Depositor, the Servicer, the NIMs Insurer
or the Trustee of a breach of any of such representations and warranties that
adversely and materially affects the value of the related Mortgage Loan,
Prepayment Charges or the interests of the Certificateholders, the party
discovering such breach shall give prompt written notice to the other parties.
Within 90 days of the discovery of such breach of any representation or
warranty, the Transferor or the Sponsor, as applicable, shall either (a) cure
such breach in all material respects, (b) repurchase such Mortgage Loan or any
property acquired in respect thereof from the Trustee at the Purchase Price or
(c) within the two year period following the Closing Date, substitute a
Replacement Mortgage Loan for the affected Mortgage


                                       67

<PAGE>

Loan. In the event of discovery of a breach of any representation and warranty
of the Transferor or the Sponsor, the Trustee shall use reasonable efforts to
enforce its rights under the Transfer Agreement or the Sale Agreement for the
benefit of Certificateholders and the NIMs Insurer. If a breach of the
representations and warranties set forth in the Transfer Agreement exists solely
due to the unenforceability of a Prepayment Charge, the Trustee shall notify the
NIMs Insurer thereof and not seek to enforce the repurchase remedy provided for
herein unless directed in writing to do so by the NIMs Insurer. In the event of
a breach of the representations and warranties with respect to the Mortgage
Loans set forth in the Transfer Agreement, the Trustee shall, at the request of
the NIMs Insurer, use reasonable efforts to enforce the right of the Trust Fund
and the NIMs Insurer to be indemnified for such breach of representation and
warranty. In the event that such breach relates solely to the unenforceability
of a Prepayment Charge, amounts received in respect of such indemnity up to the
amount of such Prepayment Charge shall be distributed pursuant to Section
4.04(b)(i). As provided in the Sale Agreement, if the Transferor substitutes for
a Mortgage Loan for which there is a breach of any representations and
warranties in the Transfer Agreement which adversely and materially affects the
value of such Mortgage Loan and such substitute mortgage loan is not a
Replacement Mortgage Loan, under the terms of the Sale Agreement, the Sponsor
will, in exchange for such substitute Mortgage Loan, (i) provide the applicable
Purchase Price for the affected Mortgage Loan or (ii) within two years of the
Closing Date, substitute such affected Mortgage Loan with a Replacement Mortgage
Loan. Any such substitution shall not be effected prior to the additional
delivery to the Trustee of a Request for Release substantially in the form of
Exhibit I and shall not be effected unless it is within two years of the Startup
Day. As provided in the Sale Agreement, the Sponsor indemnifies and holds the
Trust Fund, the Trustee, the Custodian, the Depositor, the NIMs Insurer, the
Servicer and each Certificateholder harmless against any and all taxes, claims,
losses, penalties, fines, forfeitures, reasonable legal fees and related costs,
judgments, and any other costs, fees and expenses that the Trust Fund, the
Trustee, the Custodian, the Depositor, the NIMs Insurer, the Servicer and any
Certificateholder may sustain in connection with any actions of the Sponsor
relating to a repurchase of a Mortgage Loan other than in compliance with the
terms of this Section 2.03 and the Sale Agreement, to the extent that any such
action causes (i) any federal or state tax to be imposed on the Trust Fund or
any REMIC provided for herein, including without limitation, any federal tax
imposed on "prohibited transactions" under Section 860F(a)(1) of the Code or on
"contributions after the startup day" under Section 860G(d)(1) of the Code, or
(ii) any REMIC created hereunder to fail to qualify as a REMIC at any time that
any Certificate is outstanding. In furtherance of the foregoing, if the Sponsor
is not a member of MERS and repurchases a Mortgage Loan which is registered on
the MERS System, the Sponsor, at its own expense and without any right of
reimbursement, shall cause MERS to execute and deliver an assignment of the
Mortgage in recordable form to transfer the Mortgage from MERS to the Sponsor
and shall cause such Mortgage to be removed from registration on the MERS System
in accordance with MERS' rules and regulations.

     With respect to any Mortgage Loan repurchased by the Depositor pursuant to
this Agreement, by the Sponsor pursuant to the Sale Agreement or by the
Transferor pursuant to the Transfer Agreement, the principal portion of the
funds received by the Servicer in respect of such repurchase of a Mortgage Loan
will be considered a Principal Prepayment and shall be deposited by the Servicer
in the Collection Account pursuant to Section 3.05 and the Servicer shall notify
the Trustee of its receipt of the same. The Trustee, upon receipt of notice from
the Servicer of its receipt of the full amount of the Purchase Price for a
Deleted Mortgage Loan, or upon receipt of the Mortgage File for a Replacement
Mortgage Loan substituted for a Deleted Mortgage Loan, shall release or cause to
be released and reassign to the Depositor, the Sponsor or the Transferor, as
applicable, the related Mortgage File for the Deleted Mortgage Loan and shall
execute and deliver such instruments of transfer or assignment, in each case
without recourse, representation or warranty, as shall be necessary to vest in
such party or its designee or assignee title to any Deleted Mortgage Loan
released pursuant hereto, free and clear of all security interests, liens and
other encumbrances created by this Agreement, which instruments shall be
prepared


                                       68

<PAGE>

by the Depositor or the Sponsor, and the Trustee shall not have any further
responsibility with respect to the Mortgage File relating to such Deleted
Mortgage Loan.

     With respect to each Replacement Mortgage Loan to be delivered to the
Trustee or the Custodian pursuant to the terms of this Article II in exchange
for a Deleted Mortgage Loan: (i) the Depositor, the Transferor or the Sponsor,
as applicable, must deliver to the Trustee or the Custodian the Mortgage File
for the Replacement Mortgage Loan containing the documents set forth in Section
2.01 along with a written certification certifying as to the delivery of such
Mortgage File and containing the granting language set forth in Section 2.01;
and (ii) the Depositor will be deemed to have made, with respect to such
Replacement Mortgage Loan, each of the representations and warranties made by it
with respect to the related Deleted Mortgage Loan. The Trustee or the Custodian
shall review the Mortgage File with respect to each Replacement Mortgage Loan
and certify to the NIMs Insurer and the Depositor that all documents required by
Section 2.01 have been executed and received.

     For any month in which the Sponsor substitutes one or more Replacement
Mortgage Loans for one or more Deleted Mortgage Loans, the Sponsor will
determine the amount (if any) by which the aggregate principal balance of all
such Replacement Mortgage Loans as of the date of substitution and the aggregate
Prepayment Charges with respect to such Replacement Mortgage Loans is less than
the aggregate Stated Principal Balance (after application of the principal
portion of the Scheduled Payment due in the month of substitution) and aggregate
Prepayment Charges of all such Deleted Mortgage Loans. An amount equal to the
aggregate of the deficiencies described in the preceding sentence (such amount,
the "Substitution Adjustment Amount") plus an amount equal to any unreimbursed
costs, penalties and/or damages incurred by the Trust Fund in connection with
any violation relating to such Deleted Mortgage Loan of any predatory or abusive
lending law shall be remitted by the Sponsor to the Servicer for deposit into
the Collection Account on the Determination Date for the Distribution Date
relating to the Prepayment Period during which the related Mortgage Loan became
required to be purchased or replaced hereunder.

     Notwithstanding any other provision of this Agreement, the right to
substitute Mortgage Loans pursuant to this Article II shall be subject to the
additional limitations that no substitution of a Replacement Mortgage Loan for a
Deleted Mortgage Loan shall be made unless the Trustee and the NIMs Insurer
shall each have received an Opinion of Counsel (at the expense of the party
seeking to make the substitution) that, under current law, such substitution
will not (A) affect adversely the status of any REMIC established hereunder as a
REMIC, or of the related "regular interests" as "regular interests" in any such
REMIC, or (B) cause any such REMIC to engage in a "prohibited transaction" or
prohibited contribution pursuant to the REMIC Provisions.

     The Sponsor shall cause the Mortgage Loan Schedule to be amended in
accordance with the terms of this Agreement.

     The Sponsor shall give or cause to be given written notice to the
Certificateholders and the NIMs Insurer that such substitution has taken place,

Mortgage Loan from the terms of this Agreement and the substitution of the
Replacement Mortgage Loan or Replacement Mortgage Loans and shall deliver a copy
of such amended Mortgage Loan Schedule to the NIMs Insurer, the Servicer, and
the Trustee. Upon such substitution by the Sponsor, such Replacement Mortgage
Loan or Replacement Mortgage Loans shall constitute part of the Mortgage Pool
and shall be subject in all respects to the terms of this Agreement and the Sale
Agreement, including all applicable representations and warranties thereof
included in the Sale Agreement as of the date of substitution.

     to perform any of its other obligations under this Agreement in accordance
     with the terms hereof.

          (vi) No consent, approval, authorization or order of any court or
     governmental agency or body is required for the execution, delivery and
     performance by the Servicer of, or compliance by the Servicer with, this
     Agreement or the consummation of the transactions contemplated hereby, or
     if any such consent, approval, authorization or order is required, the
     Servicer has obtained the same.

          (vii) The Servicer has fully furnished and will fully furnish (for the

     to Equifax, Experian and Trans Union Credit Information Company on a
     monthly basis.

          (viii) Notwithstanding any state or federal law to the contrary, the
     Servicer shall not impose or collect a Prepayment Charge in any instance
     when the mortgage debt is accelerated as the result of the Mortgagor's
     default in making the Mortgage Loan payments.

     SECTION 2.05. Substitutions and Repurchases of Mortgage Loans that are not
          "Qualified Mortgages."

     Upon discovery by the Depositor, the Servicer or the Trustee that any
Mortgage Loan does not constitute a "qualified mortgage" within the meaning of
section 860G(a)(3) of the Code, the party discovering such fact shall promptly
(and in any event within 5 Business Days of discovery) give written notice
thereof to the other parties. In connection therewith, the Depositor shall, at
the Depositor's option, either (i) substitute, if the conditions in Section
2.03(c) with respect to substitutions are satisfied, a Replacement Mortgage Loan
for the affected Mortgage Loan, or (ii) repurchase the affected Mortgage Loan
within 90 days of such discovery in the same manner as it would a Mortgage Loan
for a breach of representation or warranty contained in Section 2.03. The
Trustee, upon the written request of the Depositor, shall reconvey to the
Depositor the Mortgage Loan to be released pursuant hereto in the same manner,
and on the same terms and conditions, as it would a Mortgage Loan repurchased
for breach of a representation or warranty contained in Section 2.03.

     SECTION 2.06. Authentication and Delivery of Certificates.

     The Trustee acknowledges the transfer and assignment to it of the Trust
Fund and, concurrently with such transfer and assignment, the Trustee has caused
to be authenticated and delivered to or upon the order of the Depositor, in
exchange for the Mortgage Loans, Certificates duly authenticated by the
Authenticating Agent in authorized denominations evidencing ownership of the
entire Trust Fund. The Trustee agrees to hold the Trust Fund and exercise the
rights referred to above for the benefit of all


                                       71

<PAGE>

present and future Holders of the Certificates and to perform its duties set
forth in this Agreement in accordance with the provisions hereof.

     SECTION 2.07. REMIC Elections.

     (a) The Depositor hereby instructs and authorizes the Trustee to make an
appropriate election to treat each of the Upper Tier REMIC, the Lower Tier REMIC
and the SWAP REMIC as a REMIC. The Trustee shall sign the returns providing for
such elections and such other tax or information returns that are required to be
signed by the Trustee under applicable law. This Agreement shall be construed so
as to carry out the intention of the parties that each of the Upper Tier REMIC,
the Lower Tier REMIC and the SWAP REMIC be treated as a REMIC at all times prior
to the date on which the Trust Fund is terminated.

     (b) The Preliminary Statement sets forth the designations and "latest
possible maturity date" for federal income tax purposes of all interests created
hereby. The "Startup Day" for purposes of the REMIC Provisions shall be the
Closing Date. Each REMIC's fiscal year shall be the calendar year.

     The SWAP REMIC shall consist of all of the assets of the Trust Fund, other
than (i) amounts distributable to the Class P Certificates pursuant to Section
4.04(b)(i) hereof, (ii) the interests issued by the SWAP REMIC and the interests
issued by the Lower Tier REMIC, (iii) the grantor trusts described in Section
2.07 hereof, (iv) each Cap Contract and the Cap Contract Account and (v) the
Swap Agreement and the Supplemental Interest Trust. The SWAP REMIC shall issue
the SWAP REMIC Regular Interests, which shall be designated as regular interests
of such REMIC, and shall issue the Class SWR Interest, which shall be designated
as the sole class of residual interest in the SWAP REMIC. Each of the SWAP REMIC
Regular Interests shall have the characteristics set forth in the Preliminary
Statement and this Section 2.07.

     The Lower Tier REMIC shall consist of the SWAP REMIC Regular Interests. The
Lower Tier REMIC shall issue the Lower Tier REMIC Regular Interests, which shall
be designated as regular interests of such REMIC and shall issue the Class LTR
Interest, which shall be designated as the sole class of residual interest in
the Lower Tier REMIC. Each of the Lower Tier REMIC Regular Interests shall have
the characteristics set forth in its definition and the Preliminary Statement.

     The assets of the Upper Tier REMIC shall be the Lower Tier REMIC Regular
Interests. The REMIC Regular Interests shall be designated as the regular
interests in the Upper Tier REMIC and the Residual Interest shall be designated
as the sole class of residual interest in the Upper Tier REMIC. For federal
income tax purposes, the pass-through rate on each REMIC Regular Interest (other
than the Class CE Certificates, the Uncertificated Class C Interest and the
Class UT-IO Interest) and on the sole class of residual interest in the Upper
Tier REMIC shall be subject to a cap equal to the Upper Tier REMIC Net WAC Cap.

     The beneficial ownership of the Class SWR Interest, Class LTR Interest and
the Residual Interest shall be represented by the Class R Certificate. The Class
SWR Interest and Class LTR Interest shall not have a principal balance or bear
interest.

     (c) The "tax matters person" with respect to each REMIC for purposes of the
REMIC Provisions shall be the beneficial owner of the Class R Certificate;
provided, however, that the Holder of the Class R Certificate, by its acceptance
thereof, irrevocably appoints the Trustee as its agent and attorney-in-fact to
act as "tax matters person" with respect to each such REMIC for purposes of the
REMIC Provisions. If there is more than one beneficial owner of the Class R
Certificate, the "tax matters person" shall be the Person with the greatest
percentage interest in the Class R Certificate and, if there is


                                       72

<PAGE>

more than one such Person, shall be determined under Treasury regulation Section
1.860F-4(d) and Treasury regulation Section 301.6231(a)(7)-1.

     (d) (i) It is intended that the rights of each Class of the Class A, Class
M and Class B Certificates to receive payments in respect of Excess Interest
shall be treated as a right in interest rate cap contracts written by the Class
C Certificateholders in favor of the holders of each Class of the Class A, Class
M and Class B Certificates and such shall be accounted for as property held
separate and apart from the regular interests in the Upper Tier REMIC held by
the holders of the Class A (other than the Class R Certificate), Class M and
Class B Certificates, and the residual interest in the Upper Tier REMIC held by
the holder of the Class R Certificate. For information reporting requirements,
the rights of the Class A, Class M and Class B Certificates to receive payments
in respect of Excess Interest shall be assumed to have zero or a de minimis
value. This provision is intended to satisfy the requirements of Treasury
Regulations Section 1.860G-2(i) for the treatment of property rights coupled
with REMIC interests to be separately respected and shall be interpreted
consistently with such regulation. On each Distribution Date, to the extent that
any of the Class A, Class M and Class B Certificates receive payments in respect
of Excess Interest, such amounts, to the extent not derived from payments on the
Cap Contracts or the Swap Agreement, will be treated as distributed by the Upper
Tier REMIC to the Class C Certificates pro rata in payment of the amounts
specified in Section 4.04(g) and then paid to the relevant Class of Certificates
pursuant to the related interest rate cap agreement.

          (ii) It is intended that the beneficial owners of the Certificates
     (other than the Class P, Class C and Class CE Certificates) shall be
     treated as having entered into a notional principal contract with respect
     to the beneficial owners of the Class C Certificates. Pursuant to each such
     notional principal contract, all beneficial owners of each Class of
     Certificates (other than the Class P, Class C and Class CE Certificates)
     shall be treated as having agreed to pay, on each Distribution Date, to the
     beneficial owners of the Class C Certificates an aggregate amount equal to
     the excess, if any, of (i) the amount payable on such Distribution Date on
     the Corresponding REMIC Regular Interest of such Class of Certificates over
     (ii) the amount payable on such Class of Certificates on such Distribution
     Date (such excess, a "Class Payment Shortfall"). A Class Payment Shortfall
     shall be allocated to each Class of Certificates to the extent that
     interest accrued on such Class for the related Accrual Period at the
     Pass-Through Rate for a Class, computed by substituting "Upper Tier REMIC
     Net WAC Cap" for the Available Funds Cap set forth in the definition
     thereof, exceeds the amount of interest accrued on such Certificate at the
     Pass-Through Rate (without such substitution) for the related Accrual
     Period, and a Class Payment Shortfall payable from principal collections
     shall be allocated to the most subordinate Class of Certificates with an
     outstanding principal balance to the extent of such balance.

     (e) The parties intend that the portion of the Trust Fund consisting of the
Uncertificated Class C Interest, the uncertificated Class UT-IO Interest, the
rights to receive payments deemed made by the Class A, Class M and Class B
Certificates in respect of notional principal contracts described in Section
2.07(d)(ii), the Supplemental Interest Trust which holds the Swap Agreement, the
Cap Contracts, the Cap Contract Account and the obligation of the holders of the
Class C Certificates to pay amounts in respect of Excess Interest to the holders
of the Class A, Class M and Class B Certificates shall be treated as a "grantor
trust" under the Code, for the benefit of the holders of the Class C
Certificates, and the provisions hereof shall be interpreted consistently with
this intention. In furtherance of such intention, the Trustee shall (i) furnish
or cause to be furnished to the holders of the Class C Certificates information
regarding their allocable share, if any, of the income with respect to such
grantor trust, (ii) file or cause to be filed with the Internal Revenue Service
Form 1041 (together with any necessary attachments) and such other forms as may
be applicable and (iii) comply with such information reporting obligations with
respect to payments from such grantor trust to the holders of Class A, Class M,
Class B and Class C Certificates as may be applicable under the Code.


                                       73

<PAGE>

     (f) The parties intend that the portion of the Trust Fund consisting of the
right to receive amounts distributable to the Class P Certificates pursuant to
Section 4.04(b)(i) hereof shall be treated as a "grantor trust" under the Code,
for the benefit of the holders of the Class P Certificates, and the provisions
hereof shall be interpreted consistently with this intention. In furtherance of
such intention, the Trustee shall (i) furnish or cause to be furnished to the
holders of the Class P Certificates information regarding their allocable share
of the income with respect to such grantor trust and (ii) file or cause to be
filed with the Internal Revenue Service Form 1041 (together with any necessary
attachments) and such other forms as may be applicable.

     (g) The parties intend that amounts paid to the Swap Counterparty under the
Swap Agreement shall be deemed for federal income tax purposes to be paid by the
Class C Certificates first, out of funds deemed received in respect of the Class
UT-IO Interest, second, out of funds deemed received in respect of the
Uncertificated Class C Interest and third, out of funds deemed received in
respect of notional principal contracts described in Section 2.07(d)(ii), and
the provisions hereof shall be interpreted consistently with this intention. On
each Distribution Date, to the extent that amounts paid to the Swap Counterparty
are deemed paid out of funds received in respect of the Uncertificated Class C
Interest, such amounts will be treated as distributed by the Upper Tier REMIC to
the Class C Certificates pro rata in payment of the amounts specified in Section
4.04(g) and then paid to the Swap Counterparty pursuant to the Swap Agreement.

     The Supplemental Interest Trust shall be an "outside reserve fund" for
federal income tax purposes and not an asset of any REMIC. Furthermore, the
Holders of the Class C Certificates shall be the beneficial owners of the
Supplemental Interest Trust for all federal income tax purposes, and shall be
taxable on all income earned thereon.

     (h) The Class SWCE Interest shall be entitled to distributions from the
SWAP REMIC in the same amounts as all distributions on the Class CE
Certificates. All payments of principal and interest at the Net Mortgage Rate on
each of the Mortgage Loans (other than amounts distributable to the Class P
Certificates pursuant to Section 4.04(b)(i) hereof) received by the SWAP REMIC
with respect to the Mortgage Loans shall be paid to the SWAP REMIC Regular
Interests until the principal balance of all such interests have been reduced to
zero and any losses allocated to such interests have been reimbursed. Any
available funds remaining in the SWAP REMIC on a Distribution Date after
distributions to the SWAP REMIC Regular Interests shall be distributed to the
Class R Certificates on account of the Class SWR Interest. On each Distribution
Date, the Trustee shall distribute the aggregate Interest Funds (net of expenses
and payments to the Class P Certificates) with respect to each of the SWAP REMIC
Regular Interests (other than the Class SWCE Interest) based on the interest
rates for each such SWAP REMIC Regular Interest. On each Distribution Date, the
Trustee shall distribute the aggregate Principal Funds with respect to the Group
One Mortgage Loans first to the Class 1-SW1 Interest until its principal balance
is reduced to zero and then sequentially to each of the other SWAP REMIC Regular
Interests beginning with designation "1" in ascending order of their numerical
class designation, in equal amounts to each such class in such numerical
designation, until the principal balance of each such class is reduced to zero.
All losses with respect to the Group One Mortgage Loans shall be allocated among
the SWAP REMIC Regular Interests beginning with the designation "1" in the same
manner that principal distributions are allocated. On each Distribution Date,
the Trustee shall distribute the aggregate Principal Funds with respect to the
Group Two Mortgage Loans first to the Class 2-SW2 Interest until its principal
balance is reduced to zero and then sequentially to each of the other SWAP REMIC
Regular Interests beginning with designation "2" in ascending order of their
numerical class designation, in equal amounts to each such class in such
numerical designation, until the principal balance of each such class is reduced
to zero. All losses with respect to the Group Two Mortgage Loans shall be
allocated among the SWAP REMIC Regular Interests beginning with the designation
"2" in the same manner that principal distributions are


                                       74

<PAGE>

allocated. Subsequent Recoveries with respect to the Group One and Group Two
Mortgage Loans shall be allocated in the reverse fashion from the manner in
which losses are allocated.

     The Class LTCE Interest shall be entitled to distributions from the Lower
Tier REMIC in the same amounts as all distributions on the Class CE
Certificates. All payments received by the Lower Tier REMIC with respect to the
SWAP REMIC Regular Interests (other than the Class SWCE Interest) shall be paid
to the Lower Tier REMIC Regular Interests until the principal balance of all
such interests have been reduced to zero and any losses allocated to such
interests have been reimbursed. Any excess amounts shall be distributed to the
Class LTR Interest. On each Distribution Date, payments and losses shall be
allocated among the Lower Tier REMIC Regular Interests so that (i) each of the
Lower Tier REMIC I Marker Interests shall have a principal balance equal to 25%
of the principal balance of the Corresponding Certificates, (ii) the Class LTIX
Interest has a principal balance equal to the excess of (x) 50% of the remaining
principal balance of the Mortgage Loans over (y) the aggregate principal balance
of the Lower Tier REMIC I Marker Interests (if necessary to reflect an increase
in overcollateralization, accrued and unpaid interest on the Class LTIX interest
may be added to its principal amount to achieve this result) and (iii) the
aggregate principal amount of the Class LTII1A Interest, Class LTII1B Interest,
Class LTII2A Interest, Class LTII2B Interest and the Class LTIIX Interest shall
equal 50% of the remaining principal balance of the Mortgage Loans.
Distributions and losses allocated to the Lower Tier REMIC Regular Interests
described in clause (iii) of the preceding sentence will be allocated among such
Lower Tier REMIC Regular Interests in the following manner: (x) such
distributions shall be deemed made to such Lower Tier REMIC Regular Interests
first, so as to keep the principal balance of the each such Lower Tier REMIC
Regular Interest with "B" at the end of its designation equal to 0.05% of the
aggregate scheduled principal balance of the Mortgage Loans in the related
Mortgage Group and second, to such Lower Tier REMIC Regular Interests with "A"
at the end of its designation so that the uncertificated principal balance of
each such Lower Tier REMIC Regular Interest is equal to 0.05% of the excess of
(I) the aggregate scheduled principal balance of the Mortgage Loans in the
related Mortgage Group over (II) the aggregate principal balance of Certificate
Group One, in the case of the Class LTII1A Interest, or Certificate Group Two,
in the case of the Class LTII2A Interest (except that if 0.05% of any such
excess is greater than the principal amount of the related Lower Tier REMIC II
Marker Interest with "A" at the end of its designation, the least amount of
principal shall be distributed to each Lower Tier REMIC II Marker Interest with
"A" at the end of its designation such that the Lower Tier REMIC Subordinated
Balance Ratio is maintained) and finally, any remaining distributions of
principal to the Cla
