                  MORTGAGE LOAN PURCHASE AGREEMENT ("Agreement") dated as of
December 1, 1999 between GreenPoint Mortgage Funding, Inc., a New York
corporation ("Seller"), and GreenPoint Mortgage Securities Inc., a Delaware
corporation ("Purchaser").

                  WHEREAS, Seller desires to sell from time to time to Purchaser
the Initial Mortgage Loans and Subsequent Mortgage Loans (each as hereinafter
defined), and Purchaser desires to purchase such Initial Mortgage Loans and
Subsequent Mortgage Loans in accordance with the terms and conditions set forth
in this Agreement.

                  NOW, THEREFORE, the parties, in consideration of good and
valuable consideration, the receipt and sufficiency of which is hereby
acknowledged, and intending to be legally bound, hereby agree as follows:


                                    ARTICLE I

                                   Definitions

                  All capitalized terms used in this Agreement and not otherwise
defined herein, shall have the meanings assigned thereto in Annex A to the
Indenture dated as of December 1, 1999, between the Issuer and the Indenture
Trustee, as the same may be amended and supplemented from time to time.


                                   ARTICLE II

                  Procedures for Purchases of Mortgage Loans; Conditions
Precedent; Settlements

                  Section 2.01. Purchase and Sale. (a) On the Closing Date in
consideration for the Purchase Price the Seller hereby sells, transfers,
assigns, sets over and otherwise conveys to the Purchaser, without recourse, all
of its right, title and interest in, to and under, whether now existing or
hereafter created, (i) each Initial Mortgage Loan, including its Principal
Balance (and any Additional Balances) and all collections in respect thereof
received on or after the Initial Cut-Off Date; (ii) property that secured a
Mortgage Loan that is acquired by foreclosure or deed in lieu of foreclosure;
(iii) the Seller's rights under the hazard insurance policies; (iv) any and all
Subsequent Mortgage Loans (including any Additional Balances related thereto)
and (v) all proceeds with respect to the foregoing.

                  (b) Each such purchase with respect to the Subsequent Mortgage
Loans shall be initiated by the Seller pursuant to the delivery to the Purchaser
of a Purchase Request in the manner set forth in Section 2.04.

                  (c) To the extent that the fair market value of any Additional
Balance or Subsequent Mortgage Loan sold by the Seller to the Purchaser is
greater than the cash consideration paid by the Purchaser for such Additional
Balance or Subsequent Mortgage Loan, the difference between such fair market
value and the amount of such cash consideration shall be deemed to be a capital
contribution made to the Seller by the Purchaser.


<PAGE>

                  Section 2.02. Delivery of Documents; Purchase of Initial
Mortgage Loans. Prior to the purchase of the Initial Mortgage Loans:

                  (a) Seller shall have delivered to the Purchaser or any agent
appointed by the Purchaser the Mortgage File for each of the Mortgage Loans.

                  (b) Purchaser shall have received a Mortgage Loan Schedule
pertaining to the related Mortgage Loans.

                  (c) Purchaser shall have received copies of the resolutions of
the Board of Directors of Seller, certified by its respective Secretary,
approving this Agreement.

                  (d) Purchaser shall have received the Certificate of
Incorporation of Seller certified by the Secretary of State of the State of New
York.

                  (e) Purchaser shall have received a certificate of the
Secretary or Assistant Secretary of Seller certifying (i) the names and
signatures of the officers authorized on its behalf to execute this Agreement,
and any other documents to be delivered by it hereunder and (ii) a copy of
Seller's By-laws.

                  (f) Purchaser shall have received an opinion of counsel to
Seller as to the due authorization, execution and delivery by the Seller of this
Agreement and as to the validity and enforceability of the transfers
contemplated hereunder and addressing such other matters as the Purchaser may
reasonably request.

                  (g) Seller shall have instructed the applicable debtor,
trustee, paying agent, authenticating agent, transfer agent, registrar,
predecessor in interest, owner (if the Mortgage Loans are in the form of a
security agreement), or servicer, if any, in respect of the related Mortgage
Loans to reflect on their books and records the transfer of such Mortgage Loans
to Purchaser, as owner or secured party (if the Mortgage Loans are in the form
of a security agreement).

                  (h) Purchaser shall have received the most recent available
standard servicing or lien reports in summary form, if any, with respect to all
of the mortgages in Seller's portfolio similar to the Mortgage Loans.

                  (i) The Purchaser shall be permitted to perform its standard
loan review of each Mortgage Loan to be purchased.

                  (j) UCC-1 financing statements duly executed by Seller as
debtor shall have been filed in California naming the Purchaser as secured party
and the Indenture Trustee on behalf of the Trust as assignee.

                  Section 2.03. Delivery of Documents; Purchases of Subsequent
Mortgage Loans. Prior to any purchase of Subsequent Mortgage Loans after the
purchase of Initial Mortgage Loans, the actions, conditions and deliveries
specified in Section 2.02 shall have been taken or made, as the case may be with
respect to the Subsequent Mortgage Loans.

                  Section 2.04. Purchase Requests. Seller shall deliver to
Purchaser a Purchase Request at least three Business Days prior to the proposed
Purchase Date for any Purchase of Subsequent Mortgage Loans (unless otherwise
agreed by the parties). Purchaser shall indicate its acceptance or declination
of each Purchase Request by completing the appropriate section of the Purchase
Request and returning the copy thereof to Seller; provided, however, that
Purchaser hereby agrees to accept each Purchase Request if all of the conditions
to such Purchase provided for in this Agreement (including, without limitation,
Section 2.02 hereof and the conditions with respect to the purchase of
Subsequent Mortgage Loans) have been satisfied.

                  With respect to all Purchase Requests, if Purchaser does not
send a copy of a completed Purchase Request to Seller within at least three
Business Days prior to the proposed Purchase Date (five Business Days, if the
related Purchase Request was received by Purchaser at least two calendar weeks
prior to the proposed Purchase Date), Purchaser shall be deemed to have accepted
such Purchase Request. Each Purchase Request accepted by Purchaser shall be
irrevocable and binding on Purchaser and Seller. Seller shall indemnify
Purchaser and hold it harmless against any Losses incurred by Purchaser as a
result of any failure by Seller to timely deliver the Subsequent Mortgage Loans
subject to such Purchase. On the applicable Purchase Date, the Purchaser shall
pay Seller the Purchase Price for the related Subsequent Mortgage Loans against
receipt of the documents required to be delivered by Seller pursuant to Section
2.03.

                  Section 2.05. Survival of Representations. The terms and
conditions of the purchase of each Mortgage Loan shall be as set forth in this
Agreement. Seller will be deemed on the Closing Date and on each Purchase Date
to have made to Purchaser the representations and warranties set forth in
Article IV hereof and such representations and warranties of Seller shall be
true and correct on and as of the Closing Date and on and as of such Purchase
Date. Each Purchase Request made by Seller shall be deemed to be a restatement
of each of the covenants of Seller made pursuant to Article V of this Agreement.
In addition, Seller shall reaffirm the representations and warranties contained
in Article IV on the date of disposition of the Mortgage Loans by the Purchaser
pursuant to the Sale and Servicing Agreement.

                  Section 2.06. Proceeds of Mortgage Loans. The transfer and
sale hereby of all of the Seller's right, title and interest in and to each
Mortgage Loan shall include all proceeds, products and profits derived
therefrom, including, without limitation, all scheduled payments of principal of
and interest on such Mortgage Loans and other amounts due or payable or to
become due or payable in respect thereof and proceeds thereof, including,
without limitation, all moneys, goods and other tangible or intangible property
received upon the liquidation or sale thereof.

                  Section 2.07. Defective Mortgage Loans. If any Mortgage Loan
is re-transferred to the Purchaser pursuant to Section 2.03 of the Sale and
Servicing Agreement, the Seller shall, at the Purchaser's option, either (a)
repurchase such Mortgage Loan at the Repurchase Price, or (b) provide an
Eligible Substitute Mortgage Loan if the Seller has any such loans available for
sale at the time, subject to the terms and conditions of the Sale and Servicing
Agreement.

                                  ARTICLE III

                      Intent of Parties; Security Interest

                  Section 3.01. Intent of Parties; Security Interest. Purchaser
and Seller confirm that the transactions contemplated herein are intended as
purchases and sales rather than as loan transactions. In the event, for any
reason, and solely in such event, any transaction hereunder is construed by any
court or regulatory authority as a loan or other purchase and sale of the
related Mortgage Loans, Seller shall be deemed to have hereby pledged to
Purchaser as security for the performance by Seller of all of its obligations
from time to time arising hereunder and under any and all Purchases effected
pursuant thereto, and shall be deemed to have granted to Purchaser a security
interest in, the related Mortgage Loans and all distributions in respect
thereof, and the proceeds of any and all of the foregoing (collectively, the
"Collateral"). In furtherance of the foregoing, (i) this Agreement shall
constitute a security agreement, (ii) Purchaser shall have all of the rights of
a secured party with respect to the Collateral pursuant to applicable law and
(iii) Seller shall execute all documents, including, but not limited to,
financing statements under the Uniform Commercial Code as in effect in any
applicable jurisdictions, as the Purchaser may reasonably require to effectively
perfect and evidence Purchaser's first priority security interest in the
Collateral. Seller also covenants not to pledge, assign or grant any security
interest to any other party in any Mortgage Loan sold to Purchaser.


                                   ARTICLE IV

                         Representations and Warranties

                  Section 4.01. Representations and Warranties of Seller. The
Seller represents, warrants and covenants to the Purchaser as of the Closing
Date and, with respect to the Subsequent Mortgage Loans, as of each related
Subsequent Transfer Date, that:

                  (i) the Seller is duly organized, validly existing and in good
     standing under the laws of the State of New York and is duly authorized and
     qualified to transact any and all business contemplated by this Agreement
     to be conducted by the Seller in any state in which a Mortgaged Property is
     located to the extent necessary to ensure the enforceability of each
     Mortgage Loan and the servicing of the Mortgage Loan in accordance with the
     terms of this Agreement;

                  (ii) the Seller has the full corporate power and authority to
     service each Mortgage Loan, and to execute, deliver and perform, and to
     enter into and consummate the transactions contemplated by this Agreement
     and the execution, delivery and performance of this Agreement by the Seller
     has been duly authorized by all necessary corporate action on the part of
     the Seller; and this Agreement, assuming the due authorization, execution
     and delivery thereof by the Purchaser, constitutes a legal, valid and
     binding obligation of the Seller, enforceable against the Seller in
     accordance with its respective terms, except to the extent that (a) the
     enforceability thereof may be limited by federal or state bankruptcy,
     insolvency, moratorium, receivership and other similar laws relating to
     creditors' rights generally and (b) the remedy of specific performance and
     injunctive and other forms of


                                       4
<PAGE>

     equitable relief may be subject to the equitable defenses and to the
     discretion of the court before which any proceeding therefor may be
     brought;

                  (iii) the execution and delivery of this Agreement by the
     Seller, the servicing of the Mortgage Loans by the Seller hereunder, the
     consummation by the Seller of the transactions herein contemplated, and the
     fulfillment by the Seller of or compliance by the Seller with the terms
     hereof will not (A) result in a breach of any term or provision of the
     charter or by-laws of the Seller or (B) conflict with, result in a breach,
     violation or acceleration of, or result in a default under, the terms of
     any other material agreement or instrument to which the Seller is a party
     or by which it may be bound, or any statute, order or regulation applicable
     to the Seller of any court, regulatory body, administrative agency or
     governmental body having jurisdiction over the Seller, which breach,
     violation, default or non-compliance would have a material adverse effect
     on (a) the business, operations, financial condition, properties or assets
     of the Seller taken as a whole or (b) the ability of the Seller to perform
     its obligations under this Agreement; and the Seller is not a party to,
     bound by, or in breach or violation of any material indenture or other
     material agreement or instrument, or subject to or in violation of any
     statute, order or regulation of any court, regulatory body, administrative
     agency or governmental body having jurisdiction over it, which materially
     and adversely affects or, to the Seller's knowledge, would in the future
     reasonably be expected to materially and adversely affect, (x) the ability
     of the Seller to perform its obligations under this Agreement or (y) the
     business, operations, financial condition, properties or assets of the
     Seller taken as a whole;

                  (iv) the Seller is, and currently intends to remain, in good
     standing and qualified to do business in each jurisdiction where failure to
     be so qualified or licensed would have a material adverse effect on (a) the
     business, operations, financial condition, properties or assets of the
     Seller taken as a whole or (b) the enforceability of any Mortgage Loan or
     the servicing of the Mortgage Loans in accordance with the terms of this
     Agreement;

                  (v) there is no litigation pending or, to the Seller's actual
     knowledge, overtly threatened against the Seller that would materially and
     adversely affect the execution, delivery or enforceability of this
     Agreement or the ability of the Seller to service the Mortgage Loans or for
     the Seller to perform any of its other obligations hereunder 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 Seller of, or compliance by the Seller with, this
     Agreement or the consummation of the transactions contemplated hereby
     (except for such consents, approvals, authorizations, or orders to be
     obtained in connection with each Purchase Date with respect to future
     transactions to be consummated hereunder), or if any such consent,
     approval, authorization or order not relating to a future transaction is
     required, the Seller has obtained the same; and

                  (vii) the Seller has caused to be performed any and all acts
     required to preserve the rights and remedies of the Purchaser in any
     insurance policies of the Seller or a mortgagee applicable to the Mortgage
     Loans sold by the Seller.

                  (iv) As of the Closing Date with respect to the Initial

                  Section 4.04. Remedies for Breach of Representations and
Warranties; Repurchase Obligation. It is understood and agreed that the
representations and warranties set forth in Section 4.01 and 4.02 shall survive
each sale of Mortgage Loans to the Purchaser and shall inure to the benefit of
the Purchaser and subsequent transferees notwithstanding any restrictive or
qualified endorsement on any Mortgage Note or Assignment of Mortgage or the
examination or failure to examine any Mortgage File. With respect to the
representations and warranties contained in Sections 4.01 and 4.02 which are
made to the best of the Seller's knowledge or to the actual knowledge of the
Seller, if it is discovered by either the Seller or the Purchaser that the
substance of such representation and warranty is inaccurate and such inaccuracy
materially and adversely affects the value of the related Mortgage Loan or the
Purchaser's interest therein, then notwithstanding the Seller's lack of
knowledge with respect to the inaccuracy at the time the representation or
warranty was made, the Seller shall repurchase the related Mortgage Loan in
accordance with this Section 4.04 as if the applicable representation or
warranty was breached, subject to the terms and conditions of the Sale and
Servicing Agreement. Upon discovery by either the Seller or the Purchaser of a
breach of any of the foregoing representations and warranties which materially
and adversely affects the value of the Mortgage Loans or the interest of the
Purchaser (or which materially and adversely affects the interests of the
Purchaser in the related Mortgage Loan in the case of a representation and
warranty relating to a particular Mortgage Loan), the party discovering such
breach shall give prompt written notice to the others.

                  Within 60 days of the earlier of either discovery by or notice
to the Seller of any breach of a representation or warranty which materially and
adversely affects the value of any Mortgage Loan or the Purchaser's interest
therein, the Seller shall use its best efforts promptly to cure such breach in
all material respects and, if such breach cannot be cured or is not cured or is
not being diligently pursued as evidenced by a notice acceptable to the
Purchaser, as evidenced by the Purchaser's agreement thereto, at the end of such
60-day period, the Seller shall, at the Purchaser's option, either (a)
repurchase such Mortgage Loan at the Repurchase Price, or (b) provide an
Eligible Substitute Mortgage Loan, if the Seller has any such loans available
for sale at the time subject to the terms and conditions of the Sale and
Servicing Agreement.

                  At the time of repurchase or substitution, the Purchaser and
the Seller shall arrange for the assignment of such Mortgage Loan to the Seller
and the delivery by the Purchaser to the Seller of the related Mortgage Files.

                  In addition to such cure and repurchase obligation, the Seller
shall indemnify the Purchaser and hold it harmless against any losses, damages,
penalties, fines, forfeitures, reasonable and necessary legal fees and related
costs, judgments, and other costs and expenses resulting from any claim, demand,
defense or assertion based on or grounded upon, or resulting from, a breach of
the representations and warranties contained in this Article IV (notwithstanding
any limitation in such representation and warranty as to the Seller's
knowledge). It is understood and agreed that the obligations of the Seller set
forth in this Section 4.04 to cure or repurchase a defective Mortgage Loan and

                  Any cause of action against the Seller relating to or arising

the Purchaser or notice thereof by the Seller to the Purchaser, (ii) failure by
the Seller to cure such breach or repurchase such Mortgage Loan as specified

Seller provides Purchaser with a notice specifying the reason for the delay and
a date, within a reasonable time period (as determined by Purchaser), on which

failure to deliver such financial statements within the above-specified 90 days,
as the case may be, shall not be deemed to be an Event of Termination of this
Agreement.

lawful, promptly upon filing, deliver to Purchaser copies of all material public
filings made by Seller with any governmental or quasi-governmental body.

delinquencies with respect to each Mortgage Loan acquired by Purchaser and (ii)
prepare and deliver reports each month, detailing, with respect to all
Purchases, such information as the Purchaser may from time to time reasonably
request.

incorporated, validly existing and in good standing as a domestic corporation in

its obligations under this Agreement.

sufficient net capital and liquid assets (or ability to access the same) to

responsible for any obligations of any other person, entity or affiliate,
including, without limitation, whether directly or indirectly by agreement to

                                   ARTICLE VI

             Sale of Mortgage Loans from the Purchaser to the Trust

                  Section 6.01. Sale and Servicing Agreement. It is the intent
of the Seller and the Purchaser that with respect to the Mortgage Loans, the
Purchaser shall concurrently sell all of its right, title and interest to the
Mortgage Loans and all other property conveyed to it hereunder to the Trust
pursuant to the Sale and Servicing Agreement.

                  With respect to such sale, the Seller agrees:

                  (i) to cooperate fully with the Purchaser and the Trust with
     respect to all reasonable requests and due diligence procedures including
     participating in meetings with Rating Agencies, the Insurer and such other
     parties as the Purchaser shall designate and participating in meetings with
     the Trust and providing information reasonably requested by the Trust;

                  (ii) to execute the Sale and Servicing Agreement and all other
     necessary documents to effect the transactions contemplated therein;

                  (iii) the Seller shall make the representations and warranties
     set forth herein regarding the Seller and the Mortgage Loans as of the date
     of the transfer to the Trust;

                  (iv) to deliver to the Purchaser for inclusion in any
     prospectus or other offering material such publicly available information
     regarding the Seller, its financial condition and the mortgage loan
     delinquency, foreclosure and loss experience of its portfolio as is


                                       16
<PAGE>

     customarily set forth in a prospectus supplement with respect to a
     comparable mortgage pool, the underwriting of mortgage loans, the servicer,
     the servicing and collection of mortgage loans, lending activities and loan
     sales of the servicer, regulatory matters and delinquency and loss
     experience and any additional information reasonably requested by the
     Purchaser, and to deliver to the Purchaser unaudited consolidated financial
     statements of the Seller, in which case the Purchaser shall bear the cost
     of having such statements audited by certified public accountants if the
     Purchaser desires such an audit, or as is otherwise reasonably requested by
     the Purchaser and which the Seller is capable of providing without
     unreasonable effort or expense, and to indemnify the Purchaser and its
     affiliates for material misstatements or omissions contained in such
     information;

                  (v) to deliver to the Purchaser and to any person designated
     by the Purchaser, at the Purchaser's expense, such statements and audit
     letters issued by reputable, certified public accountants pertaining to
     information provided by the Seller pursuant to clause (iv) above as shall
     be reasonably requested by the Purchaser (it being acknowledged by
     Purchaser that the delivery of such statements and letters is subject to
     the consent of such accountants);

                  (vi) to deliver to the Purchaser, and to any Person designated
     by the Purchaser, such legal documents and in-house opinions of counsel as
     are customarily delivered by originators or servicers, as the case may be,
     and reasonably determined by the Purchaser to be necessary in connection
     with the transactions contemplated by the Sale and Servicing Agreement, it
     being understood that the cost of any opinions of outside special counsel
     that may be required shall be the responsibility of the Seller;

                  (vii) to cooperate fully with the Purchaser and any
     prospective Purchaser with respect to the preparation of Mortgage Loan
     documents and other documents and with respect to servicing requirements
     reasonably requested by the Rating Agencies and the Insurer; and

                  (viii) to negotiate and execute one or more custodial and
     servicing agreements among the Purchaser, the Seller and a third party
     custodian/trustee which is generally considered to be a prudent
     custodian/trustee in the secondary mortgage market designated by the
     Purchaser in its sole discretion after consultation with the Seller, in
     either case for the purpose of securitizing the Mortgage Loans.


                                  ARTICLE VII

                  Upon the occurrence of a Rapid Amortization Event due to an
act or omission of the Seller (an "Event of Termination"), the Purchaser and its
assignees shall have, in addition to all other rights and remedies under this
Agreement or otherwise, all other rights and remedies provided under the UCC of
each applicable jurisdiction and other applicable laws, which rights shall be
cumulative. Without limiting the foregoing, the occurrence of an Event of
Termination shall not deny to the Purchaser or its assignees any remedy in
addition to termination of its obligations to make purchases hereunder to which
the Purchaser or its assignee may be otherwise appropriately entitled, whether
by statute or applicable law, at law or in equity.


                                   ARTICLE X

                            Payment of Purchase Price

                  Section 10.01. Purchase Price Payments. On the Closing Date,

Additional Balances relating to Mortgage


                                       18

Loans are funded by the Seller, on the terms and subject to the conditions of
this Agreement, the Purchaser shall pay to the Seller the applicable Purchase
Price by (i) making or causing to be made a cash payment to the Seller or its
designee in such amount determined by the Purchaser, (ii) crediting the Seller
with an additional capital contribution to the Purchaser, (iii) automatically
increasing the principal amount outstanding under the Purchaser Note by the
amount of the excess of the Purchase Price to be paid to the Seller for such
purchased assets over the amount of any cash payment made on such day to the
Seller and/or any capital contribution made by the Seller to the Purchaser,
subject to a cap on such note at any time equal to $10 million or (iv) any
combination of the foregoing. Such $10 million cap may be increased upon the
occurrence of and in the amount of any cash capital contributions made by the
Seller to the Purchaser.

                  Section 10.02. The Purchaser Note.

                  (a) On the Closing Date, the Purchaser shall deliver to the
Seller a promissory note, substantially in the form of Exhibit A, payable to the
order of the Seller (such promissory note, as the same has been or hereafter may
be amended, supplemented, endorsed or otherwise modified from time to time,
together with any promissory note issued from time to time in substitution
therefor or renewal thereof in accordance with this Agreement, being herein
called the "Purchaser Note"), which Purchaser Note shall, in accordance with its
terms, be subordinated to all interests of the Trust, all claims to the cash
flows from Trust assets and all obligations of the Purchaser, of any nature, now
or hereafter arising under or in connection with the Sale and Servicing
Agreement. The Purchaser Note shall evidence all amounts outstanding thereunder
as of the Closing Date in addition to amounts subsequently incurred thereunder
as provided in this Agreement. Subject to the foregoing, the Purchaser Note
shall be payable in full on the date which is one year and one day after the
Termination Date. The Purchaser Note shall bear interest at the "prime rate" as
determined by the Indenture Trustee from time to time in effect. The Purchaser
may prepay all or part of the outstanding balance of the Purchaser Note and
interest accrued thereon from time to time without any premium or penalty,
unless an Event of Default has occurred and is continuing or would result from
such prepayment or payment.

                  (b) The Servicer shall hold the Purchaser Note for the benefit
of the Seller, and shall make all appropriate recordkeeping entries with respect
to the Purchaser Note or otherwise to reflect the payments on and adjustments of
the Purchaser Note. The Servicer's books and records shall constitute rebuttable
presumptive evidence of the principal amount of and accrued interest on the
Purchaser Note at any time. The Seller hereby irrevocably authorizes the
Servicer to mark the Purchaser Note "CANCELLED" and to return the Purchaser Note
to the Purchaser upon the full and final payment thereof after the Termination
Date.

                  (c) The Seller hereby agrees not to transfer, assign, exchange
or otherwise convey or pledge, hypothecate or otherwise grant a security
interest in the Purchaser Note or any interest represented thereby, and any
attempt to transfer, assign, exchange, convey, pledge, hypothecate or grant a
security interest in the Purchaser Note or any interest represented thereby
shall be void and of no effect.

issuance of the Class A-1 Notes and Class A-2 Notes; provided, however, that
copies of this Agreement may be included as part of any filing made pursuant to
the Securities Act of 1933 and the Securities Exchange Act of 1934 and any

                  This Agreement may be amended from time to time only by
written agreement of Seller and Purchaser with the prior written consent of the
Insurer, which consent shall not be


                                       20

unreasonably withheld. Any forbearance, failure, or delay by a party in
exercising any right, power, or remedy hereunder shall not be deemed to be a
waiver thereof, and any single or partial exercise by a party of any right,
power or remedy hereunder shall not preclude the further exercise thereof. Every
right, power and remedy of a party shall continue in full force and effect until
specifically waived by it in writing. No right, power or remedy shall be

                                Entire Agreement

                  This Agreement, including the Exhibits and Schedules hereto,
contains the entire agreement of the parties hereto with respect to the subject
matter hereof, and supersedes all prior and contemporaneous agreements between
them, whether oral or written, of any nature whatsoever with respect to the

                                   ARTICLE XX

                                   Indemnities

                  Without limiting any other rights which Purchaser or Seller
may have hereunder or under applicable law, and in addition to any other
indemnity provided hereunder, Seller hereby agrees to indemnify Purchaser and
its respective officers, directors, agents and employees (each, an "Indemnified
Party") from and against any and all Losses incurred by any of them relating to
or resulting from:

                  (1) any representation or warranty made by Seller (or any
      officers, employees or agents of Seller) under or in connection with this
      Agreement, any periodic report required to be furnished thereunder or any
      other information or document delivered by Seller pursuant hereto, which
      shall have been false or incorrect in any material respect when made or
      deemed made;

                  (2) the failure by Seller to (a) comply with any applicable
      law, rule or regulation with respect to any Purchase or (b) perform or
      observe any material obligation or covenant hereunder; or

                  (3) the failure by Seller (if so requested by Purchaser) to
      execute and properly file, or any delay in executing and properly filing,
      financing statements or other similar instruments or documents under the
      Uniform Commercial Code of any applicable jurisdiction or other applicable
      laws with respect to the Mortgage Loans.

                  Promptly after receipt by an Indemnified Party under this
Article XX of notice of the commencement of any action, such Indemnified Party
will, if a claim in respect thereof is to be made against the indemnifying party
under this Article XX, notify the indemnifying party in writing of the
commencement thereof; but the omission so to notify the indemnifying party will
not relieve it from any liability that it may have to any Indemnified Party
otherwise than under this Article XX. In case any such action is brought against
any Indemnified Party and it notifies the indemnifying party of the commencement
thereof, the indemnifying party will be entitled to participate therein, and to
the extent that it may elect by written notice delivered to the Indemnified
Party promptly after receiving the aforesaid notice from such Indemnified Party,
to assume the defense thereof, with counsel satisfactory to such Indemnified
Party; provided, however, that if the defendants in any such action include both
the Indemnified Party and the indemnifying party and the Indemnified Party or
parties shall have reasonably concluded that there may be legal defenses
available to it or them and/or other Indemnified Parties that are different from
or additional to those available to the indemnifying party, the Indemnified
Party or


                                       22
<PAGE>

parties shall have the right to elect separate counsel to assert such legal
defenses and to otherwise participate in the defense of such action on behalf of
such Indemnified Party or parties. Upon receipt of notice from the indemnifying
party to such Indemnified Party of its election so to assume the defense of such
action and approval by the Indemnified Party of counsel, the indemnifying party
will not be liable for any legal or other expenses subsequently incurred by such
Indemnified Party in connection with the defense thereof, unless (i) the
Indemnified Party shall have employed separate counsel in connection with the
assertion of legal defenses in accordance with the proviso to the next preceding
sentence (it being understood, however, that the indemnifying party shall not be
liable for the expenses of more than one separate counsel, approved by you in
the case of Article XX, representing the Indemnified Parties under this Article
XX, who are parties to such action), (ii) the indemnifying party shall not have
employed counsel satisfactory to the Indemnified Party to represent the
Indemnified Party within a reasonable time after notice of commencement of the
action or (iii) the indemnifying party has authorized the employment of counsel
for the Indemnified Party at the expense of the indemnifying party; and except
that, if clause (i) or (iii) is applicable, such liability shall only be in
respect of the counsel referred to in such clause (i) or (iii).

                                RESPA Obligations

                  Seller agrees to discharge on Purchaser's behalf all
obligations, including, without limitation, all disclosure obligations, which
Purchaser may have under the Real Estate Settlement Procedures Act of 1974, as
amended, in connection with Purchaser's purchases of Mortgage Loans hereunder.
Purchaser agrees to provide Seller with such information as is reasonably
necessary for Seller to discharge such obligations and hereby appoints Seller as
its agent in its name for the purposes of, and only for the purposes of,
performing such obligations. Seller hereby agrees to indemnify Purchaser and its
respective officers, directors, agents and employees from any losses suffered by
any such party in connection with Seller's obligations under this Article XXI.


                                  ARTICLE XXII

                                    Survival

                  All indemnities and undertakings of Seller and Purchaser
hereunder shall survive the termination of this Agreement.


                                 ARTICLE XXIII

                                Right of Set-off

                  Upon the occurrence of any event or circumstance which
requires Seller to make a payment hereunder, Purchaser is hereby authorized then
or at any time or times thereafter, without notice to Seller (any such notice
being expressly waived by Seller), to set-off and apply any and all deposits
(general or special, time or demand, provisional or final), at any time held


                                       23
<PAGE>

and other indebtedness at any time owing by Purchaser to or for the credit or
the account of Seller against any and all of the obligations of Seller now or
hereafter existing hereunder, irrespective of whether or not Purchaser shall
have made any demand hereunder. Purchaser agrees promptly to notify Seller after
any such set-off and application made by Purchaser; provided that the failure to
give such notice shall not affect the validity of such set-off and application.
The rights of Purchaser under this Article XXIII are in addition to other rights
and remedies which Purchaser may have.


                                  ARTICLE XXIV

                               Consent to Service

                  Each party irrevocably consents to the service of process by

                     "Subordination Provisions" means, collectively, clauses (a)

                  7. Subordination Provisions. The Purchaser covenants and

agrees, that the payment of all Junior Liabilities is hereby expressly
subordinated in right of payment to the payment and performance of the Senior
Liabilities to the extent and in the manner set forth in the following clauses
of this paragraph 7:

                  (a) (i) In the event of any dissolution, winding up,
liquidation, readjustment, reorganization or other similar event relating to the
Purchaser, whether voluntary or involuntary, partial or complete, and whether in
bankruptcy, insolvency, receivership or other similar proceedings, or upon an
assignment for the benefit of creditors, or any other marshalling of the assets
and liabilities of the Purchaser or any sale of all or substantially all of the
assets of the Purchaser except pursuant to the Sale and Servicing Agreement
(such proceedings being herein collectively called "Bankruptcy Proceedings"),
and (ii) on and after the occurrence of an Event of Default, the Senior
Liabilities shall first be paid and performed in full and in cash before the
Seller shall be entitled to receive and to retain any payment or distribution in
respect of the Junior Liabilities. In order to implement the foregoing: (x) all
payments and distributions of any kind or character in respect of the Junior
Liabilities to which the Seller would be entitled except for this clause (a)
shall be made directly to the Indenture Trustee (for the benefit of the


                                       A-2
<PAGE>

Noteholders); and (y) the Seller hereby irrevocably agrees that the Indenture
Trustee (on behalf of the Noteholders), in the name of the Seller or otherwise,
may demand, sue for, collect, receive and receipt for any and all such payments
or distributions, and file, prove and vote or consent in any such Bankruptcy
Proceedings with respect to any and all claims of the Seller relating to the
Junior Liabilities, in each case until the Senior Liabilities shall have been
paid and performed in full and in cash.

                  (b) following the occurrence of any of the events described in
clause (a)(i) or (ii), in the event that the Seller receives any payment or
other distribution of any kind or character from the Purchaser or from any other
source whatsoever, in respect of the Junior Liabilities, such payment or other
distribution shall be received in trust for the Indenture Trustee and shall be
turned over by the Seller to the Indenture Trustee (for the benefit of the
Noteholders) forthwith. All payments and distributions received by the Indenture
Trustee in respect of this Note, to the extent received in or converted into
cash, may be applied by the Indenture Trustee (for the benefit of the
Noteholders) first to the payment of any and all reasonable expenses (including
reasonable attorneys' fees and legal expenses) paid or incurred by the Indenture
Trustee or the Noteholders in enforcing these Subordination Provisions, or in
endeavoring to collect or realize upon the Junior Liabilities, and any balance
thereof shall, solely as between the Seller and the Noteholders, be applied by
the Indenture Trustee toward the payment of the Senior Liabilities in a manner
determined by the Indenture Trustee to be in accordance with the Indenture; but
as between the Purchaser and its creditors, no such payments or distributions of
any kind or character shall be deemed to be payments or distributions in respect
of the Senior Liabilities.

                  (c) Upon the final payment in full and in cash of all Senior
Liabilities, the Seller shall be subrogated to the rights of the Indenture
Trustee to receive payments or distributions from the Purchaser that are
applicable to the Senior Liabilities until the Junior Liabilities are paid in
full.

                  (d) These Subordination Provisions are intended solely for the
purpose of defining the relative rights of the Seller, on the one hand, and the
Indenture Trustee (on behalf of Noteholders), on the other hand. Nothing
contained in these Subordination Provisions or elsewhere in this Note (subject
to paragraph 10 hereof) is intended to or shall impair, as between the
Purchaser, its creditors (other than the Noteholders) and the Seller, the
Purchaser's obligation, which is unconditional and absolute, to pay the Junior
Liabilities as and when the same shall become due and payable in accordance with
the terms hereof (subject to paragraph 10 hereof) and of the Purchase Agreement
or to affect the relative rights of the Seller and creditors of the Purchaser
(other than the Noteholders).

                  (e) The Seller shall not, until the Senior Liabilities have
been finally paid and performed in full and in cash, (i) cancel, waive, forgive,
transfer or assign, or commence legal proceedings to enforce or collect, or
subordinate to any obligation of the Purchaser, howsoever created, arising or
evidenced, whether direct or indirect, absolute or contingent, or now or
thereafter existing, or due or to become due (other than the Senior
Liabilities), the Junior Liabilities or any rights in respect hereof or (ii)
convert the Junior Liabilities into an equity interest in the Purchaser, unless,
in the case of each of clauses (i) and (ii) above, the Seller shall have
received the prior written consent of the Indenture Trustee and the Insurer in
each case.


                                       A-3
<PAGE>

                  (f) The Seller shall not, except without the advance written
consent of the Indenture Trustee and the Insurer, commence, or join with any
other Person in commencing, any Bankruptcy Proceedings with respect to the
Purchaser until at least one year and one day have passed since the Termination
Date.

                  (g) If, at any time, any of the payment (in whole or in part)
made with respect to any Senior Liabilities is rescinded or must be restored or
returned by the Indenture Trustee or Noteholders (whether in connection with any
Bankruptcy Proceedings or otherwise), these Subordination Provisions shall
continue to be effective or shall be reinstated, as the case may be, as though
such payment had not been made.

                  (h) The Indenture Trustee (on behalf of Noteholders) may, from
time to time, with the consent of the Insurer without notice to the Seller, and
without waiving any of its rights under these Subordination Provisions, take any
or all of the following actions: retain or obtain an interest in any property to
secure any of the Senior Liabilities; (ii) retain or obtain the primary or
secondary obligations of any other obligor or obligors with respect to any of
the Senior Liabilities; (iii) extend or renew for one or more periods (whether
or not longer than the original period), alter or exchange any of the Senior
Liabilities, or release or compromise any obligation of any nature with respect
to any of the Senior Liabilities; (iv) amend, supplement, amend and restate, or
otherwise modify the Sale and Servicing Agreement or any related document; and
(v) release its security interest in or surrender, release or permit any
substitution or exchange for all or any part of any rights or property securing
any of the Senior Liabilities, or extend or renew for one or more periods
(whether or not longer than the original period) or release, compromise, alter
or exchange any obligations of any nature of any obligor with respect to any
such rights or property.

                  (i) The Seller hereby waives: (i) notice of acceptance of
these Subordination Provisions by any of the Noteholders, (ii) notice of the
existence, creation, non-payment or non-performance of all or any of the Senior
Liabilities; and (iii) all diligence in enforcement, collection or protection
of, or realization upon, the Senior Liabilities, or any thereof, or any security
therefor.

                  (j) These Subordination Provisions constitute a continuing
offer from the Purchaser to all Persons who become the holders of, or who
continue to hold, Senior Liabilities; and these Subordination Provisions are
made for the benefit of the Noteholders, and the Indenture Trustee may proceed
to enforce such provisions on behalf of each of such Persons.

                  8. General. No failure or delay on the part of the Seller in
exercising any power or right hereunder shall operate as a waiver thereof, nor
shall any single or partial exercise of any such power or right preclude any
other or further exercise thereof or the exercise of any other power or right.
No amendment, modification or waiver of, or consent with respect to, any
provision of this Note shall in any event be effective unless (a) the same shall
be in writing and signed and delivered by the Purchaser and the Seller, and (b)
all consents required for such actions under the Purchase Agreement and the Sale
and Servicing Agreement shall have been received by the appropriate Persons. The
rights and remedies granted hereunder to the Indenture Trustee and the
Noteholders are subject to exercise as provided in the Purchase Agreement and
the Sale and Servicing Agreement.

                  9. Limitation on Interest. Notwithstanding anything in this
Note to the contrary, the Purchaser shall never be required to pay unearned
interest on any amount outstanding hereunder, and shall never be required to pay
interest on the principal amount outstanding hereunder at a rate in excess of
the maximum interest rate that may be contracted for, charged or received
without violation of applicable federal or state law.

                  10. Acknowledgment. The Seller acknowledges and agrees that it
has no rights to payment under this Note, and will not make any claim for
payment hereunder, unless funds are available for payment by the Purchaser in
excess of amounts due and payable by it at the time under the Sale and Servicing
Agreement and under all similar notes issued by the Purchaser to the Seller in
connection with any previous or future securitizations.

                  11. No Negotiation. This Note is not negotiable.

                  12. Governing Law. THIS NOTE SHALL BE DEEMED TO BE A CONTRACT
MADE UNDER AND GOVERNED BY THE INTERNAL LAWS OF THE STATE OF NEW YORK WITHOUT
REGARD TO CONFLICT OF LAWS PRINCIPLES.
