                                    PURPOSE

     1.1  GENERAL.  The purpose of the Crescent Banking Company 2001 Long-Term
          -------
Incentive Plan (the "Plan") is to promote the success, and enhance the value, of
Crescent Banking Company (the "Corporation"), by linking the personal interests
of its employees, officers, directors, and consultants to those of Corporation
shareholders and by providing such persons with an incentive for outstanding
performance.  The Plan is further intended to provide flexibility to the
Corporation in its ability to motivate, attract, and retain the services of
employees, officers, directors, and consultants upon whose judgment, interest,
and special effort the successful conduct of the Corporation's operation is
largely dependent.  Accordingly, the Plan permits the grant of incentive awards
from time to time to selected employees and officers, directors and consultants.

                                EFFECTIVE DATE

     2.1  EFFECTIVE DATE.  The Plan shall be effective as of the date upon which
          --------------
it shall be approved by the Board (the "Effective Date").  However, the Plan
shall be submitted to the shareholders of the Corporation for approval within 12
months of the Board's approval thereof.  No Incentive Stock Options granted
under the Plan may be exercised prior to approval of the Plan by the
shareholders and if the shareholders fail to approve the Plan within 12 months
of the Board's approval thereof, any Incentive Stock Options previously granted
hereunder shall be automatically converted to Non-Qualified Stock Options
without any further act.  In the discretion of the Committee, Awards may be made
to Covered Employees which are intended to constitute qualified performance-
based compensation under Code Section 162(m).  Any such Awards shall be
contingent upon the shareholders having approved the Plan.

                                   ARTICLE 3

          -----------------------
granted under the Plan must comply with the following additional rules:

          (a) EXERCISE PRICE.  The exercise price per share of Stock shall be
              --------------
     set by the Committee, provided that the exercise price for any Incentive
     Stock Option shall not be less than the Fair Market Value as of the date of
     the grant.

                                      -9-
<PAGE>

          (b) EXERCISE.  In no event may any Incentive Stock Option be
              --------
     exercisable for more than ten years from the date of its grant.

          (c) LAPSE OF OPTION.  An Incentive Stock Option shall lapse under the
              ---------------
     earliest of the following circumstances; provided, however, that the
     Committee may, prior to the lapse of the Incentive Stock Option under the
     circumstances described in paragraphs (3), (4) and (5) below, provide in
     writing that the Option will extend until a later date, but if an Option is
     exercised after the dates specified in paragraphs (3), (4) and (5) below,
     it will automatically become a Non-Qualified Stock Option:

               (1) The Incentive Stock Option shall lapse as of the option
          expiration date set forth in the Award Agreement.

               (2) The Incentive Stock Option shall lapse ten years after it is
          granted, unless an earlier time is set in the Award Agreement.

               (3) If the Participant terminates employment for any reason other
          than as provided in paragraph (4) or (5) below, the Incentive Stock
          Option shall lapse, unless it is previously exercised, three months
          after the Participant's termination of employment; provided, however,
          that if the Participant's employment is terminated by the Corporation
          for cause (as determined by the Corporation), the Incentive Stock
          Option shall (to the extent not previously exercised) lapse
          immediately.

               (4) If the Participant terminates employment by reason of his
          Disability, the Incentive Stock Option shall lapse, unless it is
          previously exercised, one year after the Participant's termination of
          employment.

               (5) If the Participant dies while employed, or during the three-
          month period described in paragraph (3) or during the one-year period
          described in paragraph (4) and before the Option otherwise lapses, the
          Option shall lapse one year after the Participant's death.  Upon the
          Participant's death, any exercisable Incentive Stock Options may be
          exercised by the Participant's beneficiary, determined in accordance
          with Section 13.5.

          Unless the exercisability of the Incentive Stock Option is accelerated
     as provided in Article 13, if a Participant exercises an Option after
     termination of employment, the Option may be exercised only with respect to
     the shares that were otherwise vested on the Participant's termination of
     employment.

          (d) INDIVIDUAL DOLLAR LIMITATION.  The aggregate Fair Market Value
              ----------------------------
     (determined as of the time an Award is made) of all shares of Stock

                                      -10-
<PAGE>

     with respect to which Incentive Stock Options are first exercisable by a
     Participant in any calendar year may not exceed $100,000.

          (e) TEN PERCENT OWNERS.  No Incentive Stock Option shall be granted to
              ------------------
     any individual who, at the date of grant, owns stock possessing more than
     ten percent of the total combined voting power of all classes of stock of
     the Corporation or any Parent or Subsidiary unless the exercise price per
     share of such Option is at least 110% of the Fair Market Value per share of
     Stock at the date of grant and the Option expires no later than five years
     after the date of grant.

          (f) EXPIRATION OF INCENTIVE STOCK OPTIONS.  No Award of an Incentive
              -------------------------------------
     Stock Option may be made pursuant to the Plan after the day immediately
     prior to the tenth anniversary of the Effective Date.

          (g) RIGHT TO EXERCISE.  During a Participant's lifetime, an Incentive
              -----------------
     Stock Option may be exercised only by the Participant or, in the case of
     the Participant's Disability, by the Participant's guardian or legal
     representative.

          (h) DIRECTORS.  The Committee may not grant an Incentive Stock Option
              ---------
     to a non-employee director.  The Committee may grant an Incentive Stock
     Option to a director who is also an employee of the Corporation or Parent
     or Subsidiary but only in that individual's position as an employee and not
     as a director.

         exercise; over

              (2) The grant price of the Stock Appreciation Right as determined
         by the Committee, which shall not be less than the Fair Market Value of
         one share of Stock on the date of grant in the case of any Stock
         Appreciation Right related to an Incentive Stock Option.

          (b) OTHER TERMS.  All awards of Stock Appreciation Rights shall be

<PAGE>

     of settlement, form of consideration payable in settlement, and any other
     terms and conditions of any Stock Appreciation Right shall be determined by
     the Committee at the time of the grant of the Award and shall be reflected
     in the Award Agreement.

                              PERFORMANCE SHARES

     9.1. GRANT OF PERFORMANCE SHARES.  The Committee is authorized to grant
          ---------------------------
Performance Shares to Participants on such terms and conditions as may be
selected by the Committee.  The Committee shall have the complete discretion to
determine the number of Performance Shares granted to each Participant.  All
Awards of Performance Shares shall be evidenced by an Award Agreement.

     9.2. RIGHT TO PAYMENT.  A grant of Performance Shares gives the Participant
          ----------------
rights, valued as determined by the Committee, and payable to, or exercisable
by, the Participant to whom the Performance Shares are granted, in whole or in
part, as the Committee shall establish at grant or thereafter.  The Committee
shall set performance goals and other terms or conditions to payment of the
Performance Shares in its discretion which, depending on the extent to which
they are met, will determine the number and value of Performance Shares that
will be paid to the Participant.

     9.3. OTHER TERMS.  Performance Shares may be payable in cash, Stock, or
          -----------
other property, and have such other terms and conditions as determined by the

     10.2.  ISSUANCE AND RESTRICTIONS.  Restricted Stock shall be subject to
            -------------------------
such restrictions on transferability and other restrictions as the Committee may
impose (including, without limitation, limitations on the right to vote
Restricted Stock or the right to receive dividends on the Restricted Stock).
These restrictions may lapse separately or in combination at such times, under
such circumstances, in such installments, upon the satisfaction of performance
goals or otherwise, as the Committee determines at the time of the grant of the
Award or thereafter.

     10.3.  FORFEITURE.  Except as otherwise determined by the Committee at the
            ----------
time of the grant of the Award or thereafter, upon termination of employment
during the

                                      -12-
<PAGE>

applicable restriction period or upon failure to satisfy a performance goal
during the applicable restriction period, Restricted Stock that is at that time
subject to restrictions shall be forfeited and reacquired by the Corporation;
provided, however, that the Committee may provide in any Award Agreement that
restrictions or forfeiture conditions relating to Restricted Stock will be
waived in whole or in part in the event of terminations resulting from specified
causes, and the Committee may in other cases waive in whole or in part
restrictions or forfeiture conditions relating to Restricted Stock.

     10.4.  CERTIFICATES FOR RESTRICTED STOCK.  Restricted Stock granted under

     11.1 GRANT OF DIVIDEND EQUIVALENTS.  The Committee is authorized to grant
          -----------------------------
Dividend Equivalents to Participants subject to such terms and conditions as may
be selected by the Committee.  Dividend Equivalents shall entitle the
Participant to receive payments equal to dividends with respect to all or a
portion of the number of shares of Stock subject to an Award, as determined by
the Committee.  The Committee may provide that Dividend Equivalents be paid or
distributed when accrued or be deemed to have been reinvested in additional
shares of Stock, or otherwise reinvested.

                                  ARTICLE 12
                           OTHER STOCK-BASED AWARDS

     12.1.  GRANT OF OTHER STOCK-BASED AWARDS.  The Committee is authorized,
            ---------------------------------
subject to limitations under applicable law, to grant to Participants such other
Awards that are payable in, valued in whole or in part by reference to, or
otherwise based on or related to shares of Stock, as deemed by the Committee to
be consistent with the purposes of the Plan, including without limitation shares
of Stock awarded purely as a "bonus" and not subject to any restrictions or
conditions, convertible or exchangeable debt securities, other rights
convertible or exchangeable into shares of Stock, and Awards valued by reference
to book value of shares of Stock or the value of securities of or the
performance of specified Parents or Subsidiaries.  The Committee shall determine

                                  ARTICLE 13
                        PROVISIONS APPLICABLE TO AWARDS

     13.1.  STAND-ALONE, TANDEM, AND SUBSTITUTE AWARDS.  Awards granted under
            ------------------------------------------
the Plan may, in the discretion of the Committee, be granted either alone or in
addition to, in tandem with, or in substitution for, any other Award granted
under the Plan.  If an Award is granted in substitution for another Award, the
Committee may

                                      -13-
<PAGE>

require the surrender of such other Award in consideration of the grant of the
new Award. Awards granted in addition to or in tandem with other Awards may be
granted either at the same time as or at a different time from the grant of such
other Awards.

     13.2.  TERM OF AWARD.  The term of each Award shall be for the period as
            -------------
determined by the Committee, provided that in no event shall the term of any
Incentive Stock Option or a Stock Appreciation Right granted in tandem with the
Incentive Stock Option exceed a period of ten years from the date of its grant
(or, if Section 7.2(e) applies, five years from the date of its grant).

     13.3.  FORM OF PAYMENT FOR AWARDS.  Subject to the terms of the Plan and
            --------------------------
any applicable law or Award Agreement, payments or transfers to be made by the
Corporation or a Parent or Subsidiary on the grant or exercise of an Award may
be made in such form as the Committee determines at or after the time of grant,
including without limitation, cash, Stock, other Awards, or other property, or
any combination, and may be made in a single payment or transfer, in
installments, or on a deferred basis, in each case determined in accordance with
rules adopted by, and at the discretion of, the Committee.

     13.4.  LIMITS ON TRANSFER.  No right or interest of a Participant in any
            ------------------
unexercised or restricted Award may be pledged, encumbered, or hypothecated to
or in favor of any party other than the Corporation or a Parent or Subsidiary,
or shall be subject to any lien, obligation, or liability of such Participant to
any other party other than the Corporation or a Parent or Subsidiary.  No
unexercised or restricted Award shall be assignable or transferable by a
Participant other than by will or the laws of descent and distribution or,
except in the case of an Incentive Stock Option, pursuant to a domestic
relations order that would satisfy Section 414(p)(1)(A) of the Code if such
Section applied to an Award under the Plan; provided, however, that the
Committee may (but need not) permit other transfers where the Committee
concludes that such transferability (i) does not result in accelerated taxation,
(ii) does not cause any Option intended to be an Incentive Stock Option to fail
to be described in Code Section 422(b), and (iii) is otherwise appropriate and
desirable, taking into account any factors deemed relevant, including without
limitation, state or federal tax or securities laws applicable to transferable
Awards.

     13.5.  BENEFICIARIES.  Notwithstanding Section 13.4, a Participant may, in
            -------------
the manner determined by the Committee, designate a beneficiary to exercise the
rights of the Participant and to receive any distribution with respect to any
Award upon the Participant's death.  A beneficiary, legal guardian, legal
representative, or other person claiming any rights under the Plan is subject to
all terms and conditions of the Plan and any Award Agreement applicable to the
Participant, except to the extent the Plan and Award Agreement otherwise
provide, and to any additional restrictions deemed necessary or appropriate by
the Committee.  If no beneficiary has been designated or survives the
Participant, payment shall be made to the Participant's estate.  Subject to the
foregoing, a beneficiary designation may be changed or revoked by a Participant
at any time provided the change or revocation is filed with the Committee.

                                      -14-
<PAGE>

     13.6.  STOCK CERTIFICATES.  All Stock certificates delivered under the Plan
            ------------------
are subject to any stop-transfer orders and other restrictions as the Committee
deems necessary or advisable to comply with federal or state securities laws,
rules and regulations and the rules of any national securities exchange or
automated quotation system on which the Stock is listed, quoted, or traded.  The
Committee may place legends on any Stock certificate or issue instructions to
the transfer agent to reference restrictions applicable to the Stock.

     13.7.  ACCELERATION UPON DEATH OR DISABILITY.  Notwithstanding any other
            -------------------------------------
provision in the Plan or any Participant's Award Agreement to the contrary, upon
the Participant's death or Disability during his employment or service as a
consultant or director, all outstanding Options, Stock Appreciation Rights, and
other Awards in the nature of rights that may be exercised shall become fully
exercisable and all restrictions on outstanding Awards shall lapse.  Any Option
or Stock Appreciation Rights Awards shall thereafter continue or lapse in
accordance with the other provisions of the Plan and the Award Agreement.  To
the extent that this provision causes Incentive Stock Options to exceed the
dollar limitation set forth in Section 7.2(d), the excess Options shall be
deemed to be Non-Qualified Stock Options.

     13.8.  ACCELERATION UPON A CHANGE IN CONTROL.  Except as otherwise provided
            -------------------------------------
in the Award Agreement, upon the occurrence of a Change in Control, all
outstanding Options, Stock Appreciation Rights, and other Awards in the nature
of rights that may be exercised shall become fully exercisable and all
restrictions on outstanding Awards shall lapse; provided, however that such
acceleration will not occur if, in the opinion of the Corporation's accountants,
such acceleration would preclude the use of "pooling of interest" accounting
treatment for a Change in Control transaction that (a) would otherwise qualify
for such accounting treatment, and (b) is contingent upon qualifying for such
accounting treatment.  To the extent that this provision causes Incentive Stock
Options to exceed the dollar limitation set forth in Section 7.2(d), the excess
Options shall be deemed to be Non-Qualified Stock Options.

     13.9.  ACCELERATION UPON CERTAIN EVENTS NOT CONSTITUTING A CHANGE IN
            -------------------------------------------------------------
CONTROL.  In the event of the occurrence of any circumstance, transaction or
-------
event not constituting a Change in Control (as defined in Section 3.1) but which
the Board deems to be, or to be reasonably likely to lead to, an effective
change in control of the Corporation of a nature that would be required to be
reported in response to Item 6(e) of Schedule 14A of the 1934 Act, the Committee
may in its sole discretion declare all outstanding Options, Stock Appreciation
Rights, and other Awards in the nature of rights that may be exercised to be
fully exercisable, and/or all restrictions on all outstanding Awards to have
lapsed, in each case, as of such date as the Committee may, in its sole
discretion, declare, which may be on or before the consummation of such
transaction or event.  To the extent that this provision causes Incentive Stock
Options to exceed the dollar limitation set forth in Section 7.2(d), the excess
Options shall be deemed to be Non-Qualified Stock Options.

                                      -15-
<PAGE>

     13.10.  ACCELERATION FOR ANY OTHER REASON.  Regardless of whether an event
             ---------------------------------
has occurred as described in Section 13.8 or 13.9 above, the Committee may in
its sole discretion at any time determine that all or a portion of a
Participant's Options, Stock Appreciation Rights, and other Awards in the nature
of rights that may be exercised shall become fully or partially exercisable,
and/or that all or a part of the restrictions on all or a portion of the
outstanding Awards shall lapse, in each case, as of such date as the Committee
may, in its sole discretion, declare.  The Committee may discriminate among
Participants and among Awards granted to a Participant in exercising its
discretion pursuant to this Section 13.10.

     13.11  EFFECT OF ACCELERATION.  If an Award is accelerated under Section
            ----------------------
13.8 or 13.9, the Committee may, in its sole discretion, provide (i) that the
Award will expire after a designated period of time after such acceleration to
the extent not then exercised, (ii) that the Award will be settled in cash
rather than Stock, (iii) that the Award will be assumed by another party to the
transaction giving rise to the acceleration or otherwise be equitably converted
in connection with such transaction, or (iv) any combination of the foregoing.
The Committee's determination need not be uniform and may be different for
different Participants whether or not such Participants are similarly situated.

     13.12.  PERFORMANCE GOALS.  The Committee may determine that any Award
             ----------- -----
granted pursuant to this Plan to a Participant (including, but not limited
to, Participants who are Covered Employees) shall be determined solely on the
basis of (a) the achievement by the Corporation or a Parent or Subsidiary of a
specified target return, or target growth in return, on equity or assets, (b)
the Corporation's stock price, (c) the Corporation's total shareholder return
(stock price appreciation plus reinvested dividends) relative to a defined
comparison group or target over a specific performance period, (d) the
achievement by the Corporation or a Parent or Subsidiary, or a business unit of
any such entity, of a specified target, or target growth in, revenue, net
income, or earnings per share, or (e) any combination of the goals set forth in
(a) through (d) above.  If an Award is made on such basis, the Committee shall
establish goals prior to the beginning of the period for which such performance
goal relates (or such later date as may be permitted under Code Section 162(m)
or the regulations thereunder), and the Committee has the right for any reason
to reduce (but not increase) the Award, notwithstanding the achievement of a
specified goal.  Any payment of an Award granted with performance goals shall be
conditioned on the written certification of the Committee in each case that the
performance goals and any other material conditions were satisfied.

     13.13.  TERMINATION OF EMPLOYMENT.  Whether military, government or other
             -------------------------
service or other leave of absence shall constitute a termination of employment
shall be determined in each case by the Committee at its discretion, and any
determination by the Committee shall be final and conclusive.  A termination of
employment shall not occur (i) in a circumstance in which a Participant
transfers from the Corporation to one of its Parents or Subsidiaries, transfers
from a Parent or Subsidiary to the Corporation, or

                                      -16-
<PAGE>

transfers from one Parent or Subsidiary to another Parent or Subsidiary, or (ii)
in the discretion of the Committee as specified at or prior to such occurrence,
in the case of a spin-off, sale or disposition of the Participant's employer
from the Corporation or any Parent or Subsidiary. To the extent that this
provision causes Incentive Stock Options to extend beyond three months from the
date a Participant is deemed to be an employee of the Corporation, a Parent or
Subsidiary for purposes of Section 424(f) of the Code, the Options held by such
Participant shall be deemed to be Non-Qualified Stock Options.

     13.14.  LOAN PROVISIONS.  With the consent of the Committee, the
             ---------------
Corporation may make, guarantee or arrange for a loan or loans to a Participant
with respect to the exercise of any Option granted under this Plan and/or with
respect to the payment of the purchase price, if any, of any Award granted
hereunder and/or with respect to the payment by the Participant of any or all
federal and/or state income taxes due on account of the granting or exercise of
any Award hereunder.  The Committee shall have full authority to decide whether
to make a loan or loans hereunder and to determine the amount, terms and
provisions of any such loan(s), including the interest rate to be charged in
respect of any such loan(s), whether the loan(s) are to be made with or without
recourse against the borrower, the collateral or other security, if any,
securing the repayment of the loan(s), the terms on which the loan(s) are to be
repaid and the conditions, if any, under which the loan(s) may be forgiven.

                                  ARTICLE 14
                         CHANGES IN CAPITAL STRUCTURE

     14.1.  GENERAL.  In the event of a corporate transaction involving the
            -------
Corporation (including, without limitation, any stock dividend, stock split,
extraordinary cash dividend, recapitalization, reorganization, merger,
consolidation, split-up, spin-off, combination or exchange of shares), the
authorization limits under Section 5.1 and 5.4 shall be adjusted
proportionately, and the Committee may adjust Awards to preserve the benefits or
potential benefits of the Awards.  Action by the Committee may include: (i)
adjustment of the number and kind of shares which may be delivered under the
Plan; (ii) adjustment of the number and kind of shares subject to outstanding
Awards; (iii) adjustment of the exercise price of outstanding Awards; and (iv)
any other adjustments that the Committee determines to be equitable.  Without
limiting the foregoing, in the event a stock dividend or stock split is declared
upon the Stock, the authorization limits under Section 5.1 and 5.4 shall be
increased proportionately, and the shares of Stock then subject to each Award
shall be increased proportionately without any change in the aggregate purchase
price therefor.

                    AMENDMENT, MODIFICATION AND TERMINATION

     15.1.  AMENDMENT, MODIFICATION AND TERMINATION.  The Board or the Committee
            ---------------------------------------
may, at any time and from time to time, amend, modify or terminate the Plan
without shareholder approval; provided, however, that the Board or Committee may

                                      -17-
<PAGE>

condition any amendment or modification on the approval of shareholders of the
Corporation if such approval is necessary or deemed advisable with respect to
tax, securities or other applicable laws, policies or regulations.

     15.2 AWARDS PREVIOUSLY GRANTED.  At any time and from time to time, the
          -------------------------
Committee may amend, modify or terminate any outstanding Award without approval
of the Participant; provided, however, that, subject to the terms of the
applicable Award Agreement, such amendment, modification or termination shall
not, without the Participant's consent, reduce or diminish the value of such
Award determined as if the Award had been exercised, vested, cashed in or
otherwise settled on the date of such amendment or termination.  No termination,
amendment, or modification of the Plan shall adversely affect any Award
previously granted under the Plan, without the written consent of the
Participant.

                                  ARTICLE 16
                              GENERAL PROVISIONS

     16.1.  NO RIGHTS TO AWARDS.  No Participant or any eligible participant
            -------------------
shall have any claim to be granted any Award under the Plan, and neither the
Corporation nor the Committee is obligated to treat Participants or eligible
participants uniformly.

     16.2.  NO SHAREHOLDER RIGHTS.  No Award gives the Participant any of the
            ---------------------
rights of a shareholder of the Corporation unless and until shares of Stock are
in fact issued to such person in connection with such Award.

     16.3.  WITHHOLDING.  The Corporation or any Parent or Subsidiary shall have
            -----------
the authority and the right to deduct or withhold, or require a Participant to

and defend the same before he undertakes to handle and defend it on his own
behalf.  The foregoing right of indemnification shall not be exclusive of any
other rights of indemnification to which such persons may be entitled under the

otherwise, or any power that the Corporation may have to indemnify them or hold
them harmless.

                      Loan pursuant to a Dry Funding structured as a
                      Rewarehousing Transaction, Purchaser shall have received
                      from Seller a Rewarehousing Loan Purchase Detail, either
                      electronically or via a facsimile transmission, an
                      original of a Warehouse Lender's or Seller's Release, and
                      the Cash Account Balance shall not be less than the sum of
                      the Supplemental Amount. Custodian shall have received all
                      applicable documents required by Section 2 of the
                      Custodial Agreement. The terms and conditions of each such
                      purchase shall be set forth in this Agreement and in the
                      applicable Funding Confirmation.

               (2)    If Purchaser elects to purchase any Mortgage Loan pursuant
                      to a Dry Funding structured as a Rewarehousing
                      Transaction, Purchaser shall (i) withdraw the Supplemental
                      Amount, if any, from the Cash Account and (ii) pay the
                      Disbursement Amount for such Mortgage Loans to the
                      Warehouse Lender or Seller by wire transfer of immediately
                      available funds in accordance with the Warehouse Lender's
                      Wire Instructions or Seller's Wire Instructions.

               (3)    With respect to each Dry Funding structured as a
                      Rewarehousing Transaction, simultaneously with the payment
                      by Purchaser of the Disbursement Amount for a Mortgage
                      Loan, in accordance with the Warehouse Lender's or
                      Seller's Wire Instructions, Seller hereby conveys to
                      Purchaser all of Seller's right, title and interest in, to
                      and under such Mortgage Loan, free and clear of all liens,
                      pledges, charges, encumbrances or security interests of
                      any nature.

               (4)    With respect to each Dry Funding structured as a
                      Rewarehousing Transaction, if a Repurchase has not
                      occurred by the Scheduled Repurchase Date and if Seller
                      has not repurchased the related Mortgage Loan(s),
                      Purchaser may elect a remedy pursuant to Section 7
                      including the application of an Incremental Pass-Through
                      Rate.

     Section 3.  Procedure for Repurchases of Mortgage Loans.
                 -------------------------------------------

     (a)  With respect to each Mortgage Loan, on either the Scheduled Collateral
Receipt Date or the Scheduled Repurchase Date, if Seller has not satisfied the
requirements of this Agreement or Purchaser has elected not to purchase such
Mortgage Loan:

          (i)    the Pass-Through Rate shall increase by the Incremental Pass-
                 Through Rate:

          (ii)   the Seller shall remit the Repurchase Price to Purchaser and
                 Purchaser shall assign, transfer and convey to Seller all of
                 Purchaser's right, title and interest in, to and under such
                 Mortgage Loan, free and clear of all liens, pledges, charges,
                 claims, encumbrances or security interests of any nature; and

          (iii)  upon receipt of the Repurchase Price and Seller's Delivery
                 Instructions from Seller, Purchaser shall direct Custodian to
                 deliver the Dry Submission Package related to such Mortgage
                 Loan pursuant to the Seller's Delivery Instructions.

     Section 4.  Terms of Each Transaction.
                 -------------------------

     (a)  The obligations of the parties hereto shall, with respect to each
Transaction, begin on a Purchase Date and terminate on the Repurchase Date or on
the satisfaction by Seller of its obligations pursuant to Section 7.

     (b)  The terms and conditions of each Transaction, including, without
limitation, the Purchase Date, the Scheduled Repurchase Date, the Mortgage Loan
subject thereto, the Purchase Price, the Pass-Through Rate, the Incremental
Pass-Through Rate, the Scheduled Collateral Receipt Date for Wet Fundings only,
the Custodial Fee and, if applicable, the Wire Fee, shall be set forth in the
related Funding Confirmation.  Each Funding Confirmation shall be deemed to be
controlling as to the related terms and provisions of the purchase of a Mortgage
Loan, absent manifest error, without regard to any other oral or written
communication between Purchaser and Seller with respect to the purchase of such
Mortgage Loan.  With respect to the purchase or repurchase of a Mortgage Loan,
in the event of any conflict between the terms and the provisions of this
Agreement and the terms and provisions of the related Funding Confirmation, the
terms and provisions of the related Funding Confirmation will prevail over the
terms and provisions of this Agreement.

     Section 5.  Cash Account.
                 ------------

     (a)  Seller hereby authorizes and directs Purchaser to create the Cash
Account.  The Cash Account shall be held in trust for Seller subject to the
terms and conditions of this Agreement.  Purchaser shall notify Seller, via
electronic or facsimile transmission, of the Cash Account Balance on each
Business Day when the Cash Account Balance is greater than zero and on each
Business Day on which a Transaction occurs hereunder.

                                      13

     (b)  Purchaser shall credit the Cash Account for (i) any deposits therein
by Seller upon Seller's written direction pursuant to a Withdrawal/Deposit
Notice, (ii) any Supplemental Amount for any Mortgage Loan upon the refunding to
Purchaser of the Disbursement Amount for such Mortgage Loan by the Escrow Agent
upon any failure to apply the Disbursement Amount in connection with the
proposed funding of a Mortgage Loan, (iii) any credit pursuant to a Cash Account
Adjustment and (iv) any Cash Account Interest Accruals.

     (c)  Purchaser shall debit the Cash Account for (i) any withdrawals

upon payment of the Disbursement Amount for such Mortgage Loan to the Escrow
Agent in accordance with Section 2(c)(1), (iii) any debit pursuant to a Cash
Account Adjustment and (iv) any Wire Fees.

     (d)  Upon termination of this Agreement and payment in full of all
obligations owing by Seller hereunder and under the Custodial Agreement,
Purchaser shall remit to Seller the Cash Account Balance.

     Section 6.  Servicing of the Mortgage Loans.
                 -------------------------------

     (a)  Seller shall service and administer each Mortgage Loan on behalf of
Purchaser in accordance with prudent mortgage loan servicing standards and
procedures generally accepted in the mortgage banking industry, provided that
Seller shall at all times comply with applicable law and the requirements of any
applicable insurer or guarantor so that the insurance in respect of any Mortgage
Loan is not voided or reduced. Seller shall at all times maintain accurate and
complete records of its servicing of each Mortgage Loan, and Purchaser may, at
any time during Seller's business hours, on reasonable notice, examine and make
copies of such records. Upon Purchaser's request, Seller shall deliver to
Purchaser reports regarding the status of each Mortgage Loan, which reports
shall include, without limitation, circumstances that could materially adversely
affect any such Mortgage Loan, Purchaser's ownership of any such Mortgage Loan
or the collateral securing any such Mortgage Loan.

     (b)  Within five Business Days of notice from Purchaser, or immediately
upon notice if an Event of Default has occurred, Seller shall establish and
maintain a Custodial Account entitled "[name of Seller], in trust for Paine
Webber Real Estate Securities Inc. and its assignees under the Mortgage Loan
Repurchase Agreement dated [the date of this Agreement]" and shall promptly
deposit into such Custodial Account, in the form received with any necessary
endorsements, all collections received in respect of each Mortgage Loan that are
payable to Purchaser as the owner of each such Mortgage Loan.

     (c)  Amounts deposited in the Custodial Account with respect to any
Mortgage Loan shall be held in trust for Purchaser as the owner of such Mortgage
Loan and shall be released only as follows:

          (1)  All amounts deposited in the Custodial Account shall be paid to
               Seller upon the repurchase by Seller of the related Mortgage
               Loans

                                      14
<PAGE>

               from Purchaser if, and to the extent that, the Repurchase Prices
               and all other amounts due and payable to Purchaser hereunder with
               respect to such Mortgage Loans have been paid. The amounts paid
               to Seller (if any) pursuant to this Section 6(c)(1) shall
               constitute Seller's sole compensation for servicing the Mortgage
               Loans as provided in this Section 6.

          (2)  If a Successor Servicer is appointed by Purchaser (either under
               the circumstances set forth in Section 7 or otherwise), or if an
               Event of Default has occurred, all amounts deposited in the
               Custodial Account shall be paid to Purchaser promptly upon such
               delivery.

          (3)  During the period that Seller acts as servicer, all amounts
               deposited in the Custodial Account shall be released only in
               accordance with Purchaser's written instructions.

    Section 7. Remedies.
               --------

    (a)   Upon the occurrence of an Event of Default, at the option of Purchaser
exercised by written notice to Seller (which option shall be deemed to have been
exercised even if no notice is given, immediately upon the occurrence of an Act
of Insolvency with respect to Seller or Parent Company), the Scheduled
Repurchase Date for each Transaction hereunder shall be deemed immediately to
occur and, upon exercise of such option, (i) Seller's obligations hereunder to
repurchase all Mortgage Loans shall thereupon become immediately due and
payable, (ii) the Pass-Through Rate applicable to each Mortgage Loan shall
increase by the Incremental Pass-Through Rate, (iii) all amounts then or
thereafter held in any Custodial Accounts and the Cash Account shall be retained
by Purchaser and applied to the aggregate unpaid Repurchase Prices owed by
Seller and to any other amounts owing by Seller hereunder or under the Custodial
Agreement and (iv) Purchaser may, with concurrent notice to Seller (A)
immediately sell in a recognized market or in any other commercially reasonable
manner at such price or prices as Purchaser may reasonably deem satisfactory,
any or all the Mortgage Loans and apply the proceeds thereof (net of any
expenses of sale) to the aggregate unpaid Repurchase Prices and any other
amounts owing by Seller hereunder or under the Custodial Agreement or (B) in its
sole discretion elect, in lieu of selling all or a portion of such Mortgage
Loans, to give Seller credit for such Mortgage Loans in an amount equal to the
price therefore on such date, obtained from a generally recognized source or the
most recent closing bid quotation from such a source, against the aggregate
unpaid Repurchase Prices and any other amounts owing by Seller hereunder or
under the Custodial Agreement, and in either case upon the determination and
receipt by Purchaser of all such amounts owing by Seller (including, without
limitation, any unpaid fees, expenses, legal fees and expenses of Purchaser's
counsel or other amounts owing to Purchaser under this Agreement or the
Custodial Agreement), Purchaser shall transfer any remaining portion of the
Mortgage Loans and proceeds thereof to either (1) Seller, if in Purchaser's
reasonable judgment Seller is legally entitled thereto, (2) such other entity as
is in Purchaser's reasonable judgment legally entitled thereto or (3) if
Purchaser cannot determine in its judgment the entity entitled thereto, a court
of competent jurisdiction;

                                      15
<PAGE>

provided that Seller shall be liable for any deficiency if the proceeds of any
sale or other disposition of the Mortgage Loans and any amounts applied from the
Custodial Account and the Cash Account are insufficient to pay all amounts to
which Purchaser is entitled hereunder.

     (b)  If any Mortgage Loan becomes a Defective Mortgage Loan prior to the
Repurchase Date, the Pass-Through Rate applicable to such Defective Mortgage
Loan shall increase by the Incremental Pass-Through Rate, and Purchaser, at its
election, may immediately accelerate the Scheduled Repurchase Date and require
that Seller, upon receipt of such election, immediately repurchase such
Defective Mortgage Loan by remitting to Purchaser (in immediately available
funds in accordance with Purchaser's Wire Instructions) the Repurchase Price for
such Defective Mortgage Loan.

     (c)  If Seller fails to comply with its obligations in the manner described
in Section 7(b), Seller's rights and obligations to service Mortgage Loans, as
provided in this Agreement, shall terminate. If an Event of Default occurs,
Seller's rights and obligations to service the Mortgage Loans, as provided in
this Agreement, shall terminate immediately, without any notice or action by
Purchaser. Upon any such termination, Purchaser is hereby authorized and
empowered as the exclusive agent for Seller to sell and transfer such rights to
service the Mortgage Loans for such price and on such terms and conditions as
Purchaser shall reasonably determine, and Seller shall not otherwise attempt to
sell or transfer such rights to service without the prior consent of Purchaser.
Seller shall perform all acts and take all action so that the Mortgage Loans and
all files and documents relating to such Mortgage Loans held by Seller, together
with all escrow amounts relating to such Mortgage Loans, are delivered to a
Successor Servicer. To the extent that the approval of any other insurer or
guarantor is required for any such sale or transfer, Seller shall fully
cooperate with Purchaser to obtain such approval. Upon exercise by Purchaser of
its remedies under this Section 7(b), Seller hereby authorizes Purchaser to
receive all amounts paid by any purchaser of such rights to service the Mortgage
Loans and to remit such amounts to Seller subject to Purchaser's rights of set-
off under this Agreement. Purchaser is hereby appointed the attorney-in-fact of
Seller for the purpose of carrying out the provisions of this Agreement and
taking any action and executing or endorsing any instruments that Purchaser may
deem necessary or advisable to accomplish the purposes hereof, including,
without limitation, completing or correcting any endorsement of a Mortgage Note
or Assignment of Mortgage, which appointment as attorney-in-fact is irrevocable
and coupled with an interest. Without limiting the generality of the foregoing,
Purchaser shall have the right and power when exercising its remedies
contemplated by this Section 7(b) to receive, endorse and collect all checks
made payable to the order of Seller representing any payment on account of the
principal of or interest on any of the Mortgage Notes and to give full discharge
for the same.

     (d)  Each Mortgage Loan required to be delivered to a Successor Servicer by
Section 7(b) shall be delivered free of any servicing rights in favor of Seller
and free of any title, interest, lien, encumbrance or claim of any kind of
Seller, and Seller shall deliver or cause to be delivered all files and
documents relating to each Mortgage Loan held by Seller to a Successor Servicer.
Seller shall promptly take such actions and

                                      16
<PAGE>

furnish to Purchaser such documents that Purchaser deems necessary or
appropriate to enable Purchaser to cure any defect in each such Mortgage Loan or
to enforce such Mortgage Loans, as appropriate.

     (e)  Seller agrees to indemnify and hold Purchaser and its assigns harmless
from and against all Losses resulting from or relating to any Event of Default.

     (f)  No election by Purchaser pursuant to this Section 7 shall relieve
Seller of responsibility or liability for any breach of or under this Agreement.

     (g)  Seller hereby grants Purchaser a right of set-off, to secure the
payment of any amounts that may be due and payable to Purchaser from Seller,
such right to be upon any and all monies or other property of Seller held or
received by Purchaser, or due and owing from Purchaser to Seller.

     Section 8.  Transfers of Mortgage Loan by Purchaser.  Purchaser may, in its
                 ---------------------------------------
sole discretion, assign all of its right, title and interest in or grant a
security interest in any Mortgage Loan sold by Seller hereunder and all rights
of Purchaser under this Agreement and the Custodial Agreement, in respect of
such Mortgage Loan to Assignee, subject only to an obligation on the part of
Assignee to deliver each such Mortgage Loan to Purchaser to permit Purchaser or
its designee to make delivery thereof to Seller on the Repurchase Date. It is
anticipated that such assignment to Assignee will be made by Purchaser, and,
Seller hereby irrevocably consents to such assignment. No notice of such
assignment shall be given by Purchaser to Seller. Assignment by Purchaser of the
Mortgage Loans as provided in this Section 8 shall not release Purchaser from
its obligations otherwise under this Agreement.

     Without limitation of the foregoing, an assignment of a Mortgage Loan to
Assignee, as described in this Section 8, shall be effective upon delivery to
Assignee of a Dry Submission Package.

     Section 9.  Record Title to Mortgage Loans, Intent of Parties, Security
                 -----------------------------------------------------------
                 Interest.
                 --------

     (a)  From and after the delivery of the related Dry Submission Package, and
subject to the remedies of Purchaser in Section 7, Seller shall remain the last
named payee or endorsee of each Mortgage Note and the mortgagee or assignee of
record of each Mortgage in trust for the benefit of Purchaser, for the sole
purpose of facilitating the servicing of such Mortgage Loan.

     (b)  Seller shall maintain a complete set of books and records for each
Mortgage Loan which shall be clearly marked to reflect the ownership interest in
each Mortgage Loan of Purchaser.

     (c)   Purchaser and Seller confirm that the Transactions contemplated
herein are intended to be sales of the Mortgage Loans by Seller to Purchaser
rather than borrowings secured by the Mortgage Loans. In the event, for any
reason, any Transaction is construed by any court or regulatory authority as a
borrowing rather than

                                      17
<PAGE>

as a sale, Seller and Purchaser intend that Purchaser or Assignee, as the case
may be, shall have a perfected first priority security interest in the
Collateral, free and clear of adverse claims. In such case, Seller shall be
deemed to have hereby granted to Purchaser or Assignee, as the case may be, a
first priority security interest in and lien upon the Collateral, free and clear
of adverse claims. In such event, this Agreement shall constitute a security
agreement, the Custodian shall be deemed to be an independent custodian for
purposes of perfection of the security interest granted to Purchaser or
Assignee, as the case may be, and Purchaser or Assignee, as the case may be,
shall have all of the rights of a secured party under applicable law. Seller
shall, not later than the date of the first purchase of a Mortgage Loan by
Purchaser under this Agreement, deliver to Purchaser a UCC-1 Financing
Statement, executed by Seller, containing a description of collateral in the
form attached hereto in Exhibit I.

     Section 10. Representations and Warranties.
                 ------------------------------

     (a)  Seller hereby represents and warrants to Purchaser as of the date
hereof and as of the date of each delivery of a Submission Package that:

                 conducted by Seller. Seller has all requisite power and
                 authority (including, if applicable, corporate power) to
                 execute and deliver this Agreement and to perform in accordance
                 herewith; the execution, delivery and performance of this
                 Agreement (including all instruments of transfer to be
                 delivered pursuant to this Agreement) by Seller and the
                 consummation of the transactions contemplated hereby have been
                 duly and validly authorized; this Agreement evidences the
                 valid, binding and enforceable obligation of Seller; and all
                 requisite action (including, if applicable, corporate action)
                 has been taken by Seller to make this Agreement valid and

                 state regulatory authority having jurisdiction over Seller is
                 required, or if required, such approval has been obtained. The
                 transfers, assignments and conveyances provided for herein are
                 not subject to the bulk transfer or any similar statutory
                 provisions in effect in any applicable jurisdiction;

          (iii)  The consummation of the transactions contemplated by this
                 Agreement are in the ordinary course of business of Seller and

                 under or result in the acceleration of any obligation under,
                 any agreement, indenture or loan or credit agreement or other
                 instrument to which Seller or its property is subject, or
                 result in the violation of any law, rule, regulation, order,

          (iv)   This Agreement, the Custodial Agreement and every document to
                 be executed by Seller pursuant to this Agreement is and will be
                 valid, binding and subsisting obligations of Seller,
                 enforceable in accordance with their respective terms. No
                 consents or approvals are required to be obtained by Seller or
                 its Parent Company for the execution, delivery and performance
                 of this Agreement or the Custodial' Agreement by Seller;

          (v)    All information relating to Seller that Seller has delivered or
                 caused to be delivered to Purchaser, including, but not limited
                 to, all documents related to this Agreement, the Custodial
                 Agreement or Seller's financial statements, and all such
                 information hereafter furnished by Seller, does not and will
                 not contain any untrue statement of a material fact or omit to
                 state a material fact necessary to make the statements made
                 therein or herein in light of the circumstances under which
                 they were made, not misleading. Seller has disclosed in writing
                 any and all facts relating to Seller that materially and
                 adversely affect or may affect the business operations or
                 financial condition of Seller or the ability of Seller to
                 perform its obligations under this Agreement;

          (vi)   There are no actions, suits or proceedings pending, or to the
                 knowledge of Seller threatened, including any claims for which
                 an action, suit or proceeding has not been commenced, against

                 any arbitrator or before any governmental commission, board,
                 bureau or other administrative agency that, in any such case,
                 if adversely determined, would have a material adverse effect
                 on the financial condition or business of Seller or the ability
                 of Seller to perform under this Agreement, each Funding
                 Confirmation and the Custodial Agreement; and

respect to each Mortgage Loan as of the related Purchase Date that:

                                      19
<PAGE>

          (i)    The Mortgage Loan conforms in all respects to the requirements
                 of this Agreement and the related Funding Confirmation;

          (ii)   Seller is the sole owner and holder of the Mortgage Loan, free
                 and clear of any and all liens, pledges, charges, claims,
                 encumbrances or security interests of any nature and has full
                 right and authority, subject to no interest or participation
                 of, or agreement with, any other party, to sell and assign the
                 same pursuant to this Agreement;

          (iii)  Seller shall have entered into a sub-servicing agreement with
                 respect to the Mortgage Loan, which agreement shall be
                 satisfactory to Purchaser in its reasonable business judgment;

          (iv)   The Mortgage is a valid and subsisting first lien on the
                 property therein described and the Mortgaged Property is free
                 and clear of all encumbrances and liens having priority over
                 the first lien of the Mortgage except for liens for real estate
                 taxes and special assessments not yet due and payable. Any
                 pledge account, security agreement, chattel mortgage or
                 equivalent document related to, and delivered to Purchaser with
                 the Mortgage, establishes in Seller a valid and subsisting
                 first lien on the property described therein, and Seller has
                 full right to sell and assign the same to Purchaser;

           (v)   Neither Seller nor any prior holder of the Mortgage has
                 modified the Mortgage in any material respect; satisfied,
                 canceled or subordinated the Mortgage in whole or in part;
                 released the Mortgaged Property in whole or in part from the
                 lien of the Mortgage; or executed any instrument of release,
                 cancellation, modification or satisfaction unless such release,
                 cancellation, modification or satisfaction does not adversely
                 affect the value of the Mortgage Loan and is contained in the
                 related Document File;

          (vi)   The Mortgage Loan is not in default, and all Monthly Payments
                 due prior to the Purchase Date and all taxes, governmental
                 assessments, insurance premiums, water, sewer and municipal
                 charges but only to the extent that such water, sewer and
                 municipal charges constitute a lien on the Mortgage Property,
                 leasehold payments and ground rents have been paid. Seller has
                 not advanced funds, or induced or solicited any advance of
                 funds by a party other than the Mortgagor directly or
                 indirectly, for the payment of any amount required by the
                 Mortgage Loan. The collection practices used by each entity
                 which has serviced the Mortgage Loan have been in all respects
                 legal, proper, prudent, and customary in the mortgage servicing
                 business. With respect to escrow deposits and payments in those
                 instances where such were

                                      20
<PAGE>

                 required, there exist no deficiencies in connection therewith
                 for which customary arrangements for repayment thereof have not
                 been made and no escrow deposits or payments or other charges
                 or payments have been capitalized under any Mortgage or the
                 related Mortgage Note;

          (vii)  There is no default, breach, violation or event of acceleration
                 existing under the Mortgage or the related Mortgage Note and no
                 event which, with the passage of time or with notice and the
                 expiration of any grace of cure period, would constitute a
                 default, breach, violation or event of acceleration; and Seller
                 has not waived any default, breach, violation or event of
                 acceleration;

          (viii) The Mortgage Loan is not subject to any right of rescission,
                 set-off, counterclaim or defense, including the defense of
                 usury, nor will the operation of any of the terms of the
                 Mortgage Note or the Mortgage, or the exercise of any right
                 thereunder, render either the Mortgage Note or the Mortgage
                 unenforceable, in whole or in part, or subject to any right of
                 rescission, set-off, counterclaim or defense, including the
                 defense of usury, and no such right of rescission, set-off,
                 counterclaim or defense has been asserted with respect thereto;

          (ix)   The Mortgage Note and the related Mortgage are genuine and each
                 is the legal, valid and binding obligation of the maker
                 thereof, enforceable in accordance with its terms. All parties
                 to the Mortgage Note and the Mortgage had legal capacity to
                 execute the Mortgage Note and the Mortgage and each Mortgage
                 Note and Mortgage have been duly and property executed by the
                 Mortgagor;

          (x)    The Mortgage Loan meets, or is exempt from, applicable state or
                 federal laws, regulations and other requirements pertaining to
                 usury, and the Mortgage Loan is not usurious;

          (xi)   Any and all requirements of any federal, state or local law
                 including, without limitation, truth-in-lending, real estate
                 settlement procedures, consumer credit protection, equal credit
                 opportunity or disclosure laws applicable to the Mortgage Loan
                 have been complied with, and Seller shall deliver to Purchaser
                 upon demand, evidence of compliance with all such requirements;

          (xii)  Either: (i) Seller and every other holder of the Mortgage, if
                 any, were authorized to transact and do business in the
                 jurisdiction in which the Mortgaged Property is located at all
                 times when such party held the Mortgage; or (ii) the loan of
                 mortgage funds, the acquisition of the Mortgage (if Seller was
                 not the original lender), the holding of the Mortgage and the
                 transfer of the Mortgage did

                                      21

<PAGE>

                   not constitute the transaction of business or the doing of
                   business in such jurisdiction;

          (xiii)   The Mortgage Loan has closed and the proceeds of the Mortgage
                   Loan have been fully disbursed; provided that, with respect
                   to Mortgage Loans originated within the previous 120 days,
                   alterations and repairs with respect to the Mortgaged
                   Property or any part thereof may have required an escrow of
                   funds in an amount sufficient to pay for all outstanding work
                   within 120 of the origination of the Mortgage Loan, and if
                   so, such funds are held in escrow by Seller, a title company
                   or other escrow agent;

          (xiv)    The related Mortgage contains customary and enforceable
                   provisions such as to render the rights and remedies of the
                   holder thereof adequate for the realization against the
                   Mortgaged Property of the benefits of the security,
                   including, (i) in the case of a Mortgage designated as a deed
                   of trust, by trustee's sale, (ii) in the case of a Mortgage
                   designated as a security deed, by non judicial sale, (iii) in
                   the case of a Mortgage designated as any other instrument
                   which provides for enforcement by a non judicial sale, by
                   nonjudicial sale, and (iv) otherwise by judicial foreclosure;

          (xv)     The Mortgage Loan was originated free of any "original issue
                   discount" with respect to which the owner of the Mortgage
                   Loan could be deemed to have income pursuant to Sections 1271
                   et sect., of the Internal Revenue Code;

          (xvi)    At origination, the Mortgaged Property was free and clear of
                   all mechanics' and materialmen's liens or liens in the nature
                   thereof which are or could be prior to the Mortgage lien, and
                   no rights are outstanding that under law could give rise to
                   any such lien;

          (xvii)   Either (i) all improvements which were considered in
                   determining the appraised value of the Mortgaged Property lay
                   wholly within the boundaries and building restriction lines
                   of the Mortgaged Property, and no improvements on adjoining
                   properties encroach upon the Mortgaged Property or (ii) the
                   short form title insurance policy insures against loss or
                   damage resulting from any encroachments of boundary lines
                   affecting the Mortgage Property;

          (xviii)  As of the closing date of origination the Mortgaged Property
                   is lawfully occupied under applicable law. All inspections,
                   licenses and certificates required to be made or issued with
                   respect to all occupied portions of the Mortgaged Property
                   and, with respect to the use and occupancy of the same,
                   including but not limited to certificates of occupancy and
                   fire underwriting certificates, have been made or obtained
                   from the appropriate authorities. The

                                      22
<PAGE>

                    Mortgagor represented at the time of origination of the
                    Mortgage Loan that the Mortgagor would occupy the Mortgaged
                    Property as the Mortgagor's primary residence (except as may
                    be otherwise permitted by the terms hereof);

          (xix)     There is no proceeding pending for the total or partial
                    condemnation of the Mortgaged Property and said property is
                    undamaged by waste, fire, earthquake or earth movement,
                    windstorm, flood, tornado or other casualty;

          (xx)      All buildings upon the Mortgaged Property are insured
                    against loss by fire, hazards of extended coverage and such
                    other hazards as are customary in the area where the
                    Mortgaged Property is located, pursuant to fire and hazard
                    insurance policies with extended coverage or other insurance
                    required by Purchaser, in an amount at least equal to the
                    greater of (i) the outstanding principal balance of the
                    Mortgage Loan or (ii) the maximum insurable value
                    (replacement cost without deduction for depreciation) of the
                    improvements constituting the Mortgaged Property. If
                    applicable laws limit the amount of such insurance to the
                    replacement cost of the improvements constituting the
                    Mortgaged Property or to some other amount, then such
                    insurance is in an amount equal to the maximum allowed by
                    such laws. Such insurance amount is sufficient to prevent
                    the Mortgagor or the loss payee under the policy from
                    becoming a co-insurer. The insurer issuing such insurance is
                    acceptable pursuant to a Program. All individual insurance
                    policies contain a standard mortgagee clause naming Seller,
                    its successors and assigns, as mortgagee and all premiums
                    thereon have been paid. Each Mortgage obligates the
                    Mortgagor thereunder to maintain all such insurance at
                    Mortgagor's cost and expense, and upon the Mortgagor's
                    failure to do so, authorizes the holder of the Mortgage to
                    obtain and maintain such insurance at Mortgagor's cost and
                    expense and to seek reimbursement therefore from the
                    Mortgagor. Any flood insurance required by applicable law
                    has been obtained;

          (xxi)     The related Mortgage Note is payable on the Due Date of each
                    month in self-amortizing monthly installments of principal
                    and interest, with interest payable in arrears, providing
                    for full amortization by maturity, over an original term of
                    not more than thirty years;

          (xxii)    The Mortgaged Property consists of a single parcel of real
                    property;

          (xxiii)   There are no circumstances or conditions with respect to the
                    Mortgage, the Mortgaged Property, the Mortgagor or the

                                      23
<PAGE>

                    Mortgagor's credit standing that can be reasonably expected
                    to cause private institutional investors to regard, the
                    Mortgage Loan as an unacceptable investment, cause the
                    Mortgage Loan to become delinquent or adversely affect the
                    value or marketability of the Mortgage Loan. As used herein,
                    "knowledge" shall be deemed to include (A) knowledge of
                    facts or conditions of which Seller (including without
                    limitation, any of its directors, officers, agents or
                    employees) either is actually aware or should have been
                    aware under the circumstances with the exercise of
                    reasonable care, due diligence and competence in discharging
                    Seller's duties, (B) all matters of public record, and (C)
                    the making of any representation or warranty that is
                    inaccurate or incomplete, unless Seller can demonstrate
                    otherwise. The term "due diligence" means the care which
                    Seller would exercise in obtaining and verifying information
                    for a loan in which Seller would be entirely dependent on
                    the property securing such loan and on the borrower's
                    creditworthiness as security to protect its investment; and

          (xxiv)    Seller originated each such Conforming Mortgage Loan in
                    accordance with FHLMC underwriting standards in effect at
                    the time the Conforming Mortgage Loan was originated and
                    each such Non-Conforming Mortgage Loan in accordance with
                    the Residential Funding Corporation underwriting standards
                    in effect at the time the Non-Conforming Mortgage Loan was
                    originated.

     The representations and warranties of Seller in this Section 9 are
unaffected by and supersede any provision in any endorsement of any Mortgage
Loan or in any assignment with respect to such Mortgage Loan to the effect that
such endorsement or assignment is without recourse or without representation or
warranty.

     Section 11.    Covenants of Seller. Seller hereby covenants and agrees with
                    -------------------
                    Purchaser as follows:

                    accountant of national standing acceptable to Purchaser;

               (ii)   Within 60 days after the end of each of the first three

                      for the then elapsed portion of the fiscal year, setting

                      in accordance with generally accepted accounting
                      principles consistently applied, in each case, subject to

                      Seller;

               (iv)   Promptly upon becoming aware thereof, notice of (1) the
                      commencement of, or any determination in, any legal,
                      judicial or regulatory proceedings, (2) any dispute

                      any case of (1) or (2), if adversely determined, would

                     MORTGAGE LOAN PARTICIPATION AGREEMENT
                     -------------------------------------

     Mortgage Loan Participation Agreement ("Agreement"), dated as of the date
set forth on the cover page hereof, between PAINE WEBBER REAL ESTATE SECURITIES
INC. ("Participant") and the Seller whose name is set forth on the cover page
hereof ("Seller").

                             PRELIMINARY STATEMENT
                             ---------------------

     Seller desires to sell to Participant from time to time Participating
Certificates evidencing a 100% undivided ownership in certain Mortgage Loans
eligible in the aggregate to back Securities with the terms described in related
Take-Out Commitments.

     Participant desires and may in its sole discretion purchase such
Participation Certificates from Seller in accordance with the terms and
conditions set forth in this Agreement.  Seller, subject to the terms hereof,
will cause (a) Mortgage Loans evidenced by a Participation Certificate to back a
GNMA Security issued and guaranteed by GNMA, a FNMA Security issued and
guaranteed by FNMA or a FHLMC Security issued and guaranteed by FHLMC and (b)
Delivery of such GNMA Security, FNMA Security or FHLMC Security by GNMA, FNMA or
FHLMC to Participant or its designee, which GNMA Security, FNMA Security of
FHLMC Security will be purchased by a Takeout Investor.

     Participant's willingness to purchase an Participation Certificate
evidencing particular Mortgage Loans is based on Participant's expectation, in
reliance upon Seller's representation and warranties herein, that such Mortgage
Loans in the aggregate, constitute a pool or pools of mortgage loans that are
eligible to back a Security and that Security, in the amount and with the terms
described in the related Take-Out Commitment, will be issued and Participant
will receive Delivery thereof within the time period agreed upon between
Participant and Seller and reflected in the terms of such Participation
Certificate.

     The amount of the Purchase Price and the Performance fee to be paid by
Participant to Seller with respect to each Participation Certificate will be
calculated on the expectation of Participant, based upon the representations and
warranties of the Seller herein, that Participant will receive Delivery of the
Security to be backed by the Mortgage Loans evidenced by the Participation
Certificate purchased by Participant on the specified Anticipated Delivery Date
and that failure to receive such Delivery will result in a material decrease in
the market value of the Participation Certificate and the underlying Mortgage
Loans considered as a whole.  During the period from the purchase of a
Participation Certificate to Delivery of the related Security, Participant
expects to rely entirely upon Seller to service Mortgage Loans evidenced by the
applicable Participation Certificate, it being acknowledged that the continued
effectiveness of Seller's Approvals during such period constitutes an essential
factor in the calculation by Participant of the Purchase Price and the
Performance Fee paid to Seller for the related Participation Certificate and
that loss of such Approvals by Seller would result in a material decrease in the
market value of the Participation Certificate and the underlying Mortgage Loans
considered as a whole.

     The parties hereto hereby agree as follows:

     Section 1.  Definitions.

purchase of such Participation Certificate to the date of such repurchase, or
(ii) deliver to Custodian a Mortgage Loan eligible to back such Security in
exchange for such Defective Mortgage Loan, which newly delivered Mortgage Loan

discretion, and such newly delivered Mortgage Loan will thereupon become one of
the Mortgage Loans evidenced by the Participation Certificate. If the aggregate
principal balance of any Mortgage Loans that are accepted by Participant
pursuant to clause (ii) of the immediately preceding sentence is less than the
aggregate principal balance of any Defective Mortgage Loan that is being
replaced by such Mortgage Loan, Seller shall remit with such Mortgage Loan to
Participant an amount equal to the difference between the aggregate principal
balance of the new Mortgage Loan accepted by Participant and the aggregate
principal balance of the Defective Mortgage Loan being replaced thereby.

     (c)(2) If Seller fails to comply with its obligations in the manner
described in Section 3(c)(1), or Seller is in breach of Section 8(a)(viii) or
8(b)(vii), not later than the third calendar day after receipt by Seller of
notice from Participant (or if such day is not a business day; the next business
day thereafter), Seller's rights and obligations to service the Mortgage Loans
evidenced by such Participation Certificate, as provided in this Agreement,

obligations to service the Mortgage Loans, as provided in this Agreement, shall
terminate immediately, without any notice or action by Participant. Upon any
such termination, Participant is hereby authorized and empowered as the
exclusive agent for Seller to sell and transfer such rights to service the
Mortgage Loans for such price and on such terms and conditions as Participant
shall reasonably determine. Seller shall not otherwise attempt to sell or
transfer such rights to service without the prior consent of Participant. Seller

files and documents relating to such Mortgage Loans held by Seller, together
with all escrow amounts relating to such Mortgage Loans, are delivered to
Successor Servicer. To the extent that the approval of the Applicable Agency is
required for any such sale or transfer, Seller shall fully cooperate with
Participant to obtain such approval. Upon exercise by Participant of its
remedies under this Section 3(c)(2), Seller hereby authorizes Participant to
receive all amounts paid by any purchaser of such rights to service the Mortgage
Loans and to remit such amounts to Seller subject to Participant's rights of
set-off under this Agreement. Upon exercise by Participant of its remedies under
this Section 3(c)(2), Participant's obligation to pay and Seller's right to
receive any portion of the Performance Fee relating to such Mortgage Loans shall
automatically be canceled and become null and void, provided that such
cancellation shall in no way relieve Seller or otherwise affect the obligation
of Seller to indemnify and hold Participant harmless as specified in Section
3(e).

relating to such Mortgage Loans held by Seller to Successor Servicer. Seller
shall promptly take such actions and furnish to Participant such documents that
Participant deems necessary or appropriate to enable Participant to obtain a
Security backed by such Mortgage Loans or to enforce such Mortgage Loans, as
appropriate.

harmless from and against all Losses (including, without limitation, Losses
incurred by Participant on account of fees paid by Participant to the Applicable
Agency to cause the Securities to be issued or any Losses in connection with any
indemnification by Participant of the Applicable Agency) resulting from or
relating to any breach or failure to perform by Seller of any representation,
warranty, covenant, term or condition made or to be performed by Seller under
this Agreement.

     (f) No exercise by Participant of its rights under this Section 3 shall
relieve Seller of responsibility or liability for any breach of this Agreement.

and each Trade Assignment, Participant will succeed to the rights and
obligations of Seller with respect to each Takeout Commitment subject to a Trade
Assignment, and that in satisfying each such Takeout Commitment, Participant
will stand in the shoes of Seller and, consequently, will be acting as a non-
dealer in exercising its rights and fulfilling its obligations assigned pursuant

pursuant to Section 5 or to Participant to permit Participant or its designee to
make delivery thereof to a Takeout Investor pursuant to Section 5. Assignment by
Participant of a Participation Certificate as provided in this Section 6 will
not release Participant from its obligations otherwise under this Agreement.

     Without limitation of the foregoing, an assignment of the Participation
Certificate to an Assignee, as described in this Section 6, shall be effective
upon delivery of the Participation Certificate to the Assignee or its designee,

Mortgage Loan which shall be clearly marked to reflect the ownership interest in
each Mortgage Loan of the holder of the related Participation Certificate.

     (c) Participant and Seller confirm that the transactions contemplated
herein are intended to be sales of the Mortgage Loans by Seller to Participant
rather than borrowings secured by the Mortgage Loans. In the event, for any
reason, any transaction is construed by any court or regulatory authority as a
borrowing rather than as a sale, the Seller and Participant intend that
Participant or its Assignee, as the case may be, shall have a perfected first
priority

                                      13

evidencing the Mortgage Loans, the Securities to be issued as contemplated
hereunder and all proceeds thereof, the Takeout Commitments and the proceeds of
any and all of the foregoing (collectively, the "Collateral"), free and clear of
adverse claims. In such case, Seller shall be deemed to have hereby granted to
Participant or its Assignee, as the case may be, a first priority security
interest in and lien upon the Collateral, free and clear of adverse claims. In
such event, this Agreement shall constitute a security agreement, the Custodian
shall be deemed to be an independent custodian for purposes of perfection of the
security interest granted to Participant, and Participant or each such Assignee
shall have all of the rights of a secured party under applicable law.

     generate an Unidentified Mortgage Loans List and shall deliver such List
     promptly to Purchaser. Purchaser shall deliver a copy of such Unidentified
     Mortgage Loans List to Seller. No action shall be taken by Custodian, other
     than in accordance with Unidentified/ Suspension Mortgage Loan Directive or
     a notice in the form of Exhibit I-3, with respect to Mortgage Loans
     appearing on an Unidentified Mortgage Loans List until any such Mortgage
     Loans are included in a Request for Certification. On each Business Day
     during which a Mortgage Loan shall appear on an Unidentified Mortgage Loans
     List, Purchaser shall send to Custodian an Unidentified/Suspension Mortgage
     Loan Directive or a notice in the form of Exhibit I-3, with respect to the
     related Submission Package.

          (ii) With respect to each Request for Certification Custodian shall:

          in the Mortgage Note and Assignment of Mortgage and (2) the "FACE
          AMOUNT", "# OF MONTHS TO MATURITY" and "NOTE RATE" columns by
          comparing such Loan Identification Data to the information in the
          Mortgage Note;

               (B) if the Program Code indicates a Cash Window Transaction,
          verify the Loan Identification Data appearing in the "LOAN #" column
          by comparing the related information in any of the related Applicable
          Agency Documents;

               (C) if the Program Code indicates a Cash Window Transaction,
          Conduit Transaction or Conversion Transaction, verify the Loan
          Identification Data appearing in the "TAKEOUT INVESTOR", "SALE PRICE",
          "COMMITMENT #", and "COMMITMENT EXPIRATION DATE" columns by comparing
          such Loan Identification Data to the information appearing in the
          Commitment; and

               (D) if the Program Code indicates a Cash Window Transaction or a
          Conduit Transaction, verify the Loan Identification Data appearing in
          the "WAREHOUSE LENDER" column by comparing such Loan Identification
          Data to the information appearing in the Warehouse Lender's Release or
          Seller's Release, as applicable.

After applying the applicable procedures set forth in clauses (A), (B) and (C)
above, any discrepancies between the Loan Identification Data and documents
comprising the Submission Package shall be noted by Custodian in the appropriate
column immediately below each item of Loan Identification Data.

     (b)  With respect to each Request for Certification, following completion
by Custodian of the procedures set forth in Section (4)(a).

          (i)  Custodian shall review each applicable set of documents
     comprising the Submission Package and shall ascertain whether (A) each such
     document is in Custodian's possession, (B) each such document accurately
     conforms with the Loan Identification Data set forth in the Request for
     Certification or as modified by any notations supplied by Custodian
     pursuant to Section 4(a)(ii), (C) each such document appears regular on its
     face, (D) each such document in the Submission Package appears on its face
     to conform to the requirements of Exhibit A, Exhibit B-1, Exhibit C-1 or
     Exhibit F, as applicable, (E) unless the Program Code indicates either a
     Dry Transaction or a Conversion Transaction, the Mortgage Loan is listed on
     a schedule attached to a Warehouse Lender's Release or a Seller's Release,
     as the case may be, (F) either (1) if the Release Payment is a dollar
     amount, the amount appearing in the "RELEASE PAYMENT" column on the Request
     for Certification is equal to or exceeds the Release Payment, or (2) if the
     Program Code indicates either a Dry Transaction or a Conversion
     Transaction, or if the Release Payment is a formula, as indicated in
     Exhibit G-1, the Custodian need not verify the amount, if any, appearing in
     the "RELEASE PAYMENT" column and (G) (1) with respect to the wire transfer
     instructions as set forth in FHLMC

                                      11
<PAGE>

     Form 987 (Wire Transfer Authorization for a Cash Warehouse Delivery) such
     wire transfer instructions are identical to Purchaser's Wire Instructions
     to Seller or (2) the Payee Number set forth on Fannie Mae Form 1068 (Fixed-
     Rate, Graduated-Payment, or Growing-Equity Mortgage Loan Schedule) or
     Fannie Mae Form 1069 (Adjustable-Rate Mortgage Loan Schedule), as
     applicable, is identical to the Payee Number that has been identified by
     Purchaser in the Request for Certification.

          (ii) If Custodian determines that the documents in the Submission
     Package and the Mortgage Loan to which they relate conform in all respects
     with Section 4(b)(i), Custodian shall so indicate in the space provided in
     its Certification Report with a Mortgage Loan Approval Code.  If Custodian
     determines that the documents in a Submission Package and the Mortgage Loan
     to which they relate conform in all respects with Section 4(b)(i) except
     that the endorsement of the Mortgage Note is missing, Custodian may, but
     shall not be obligated to, prepare such endorsement pursuant to the Limited
     Power of Attorney.  If documents in the Submission Package do not conform
     in all respects with Section 4(b)(i) or are missing and/or do not conform,
     Custodian shall annotate its Certification Report with a Mortgage Loan
     Suspension Code followed by each applicable Exception Code such that
     Purchaser is informed of each and every missing document and/or non-
     conformity in the space provided in its Certification Report.  With respect
     to each Mortgage Loan that has been given a Mortgage Loan Suspension Code,
     Purchaser shall, on each Business Day during which such Mortgage Loan
     Suspension Code is in effect, send to Custodian an Unidentified/Suspension
     Mortgage Loan Directive or a notice in the form of Exhibit 1-3, with
     respect to the related Submission Package.

     (c)  Custodian shall use its reasonable efforts to perform a Certification
with respect to any Submission Package delivered after 12:00 Noon New York City
time on a related Delivery Date for which it has received a Request for
Certification. Upon completion of its Certification, Custodian shall deliver a
Certification Report to Purchaser. All applicable documents comprising a
Submission Package relating to Mortgage Loans with respect to which Custodian
has assigned a Mortgage Loan Approval Code shall be delivered by Custodian in
the form and specific order required by Seller, via overnight courier in
accordance with the Delivery Instructions on the applicable Delivery Date and,
except with respect to Mortgage Loans for which FHLMC is the Takeout Investor,
under cover of a fully completed Notice of Bailment prepared by Custodian in
accordance with the terms of the Bailee Letter.  If Seller fails to instruct
Custodian regarding the order and specific form for a delivery to Takeout
Investor of such applicable documents, the Custodian shall deliver such
applicable documents in the original form and specific order received from
Seller. In those cases where a copy of any intervening mortgage assignment, or
an unrecorded original of any intervening mortgage assignment are delivered to
the Custodian, Seller shall cause the original of such instrument to be
recorded.  If Delivery Instructions direct Custodian to deliver any portion of a
Submission Package to a location that is not Takeout Investor's office,
Custodian must receive Purchaser's written consent to make deliveries to such
location prior to complying with such Delivery Instructions.  Upon receipt of
one written approval from Purchaser, such written approval shall, unless
Custodian receives a notice from Purchaser to the contrary, be deemed to apply
to all Delivery Instructions delivered in the future by Seller that list such
location. Following delivery by Custodian of the applicable portion of a

the form of Exhibit O, informing Custodian of all files that Purchaser has
authorized Custodian to destroy.

     All applicable documents comprising a Submission Package relating to
Mortgage Loans with respect to which Custodian has assigned a Mortgage Loan
Suspension Code shall be held by Custodian until receipt from Purchaser of
instructions. On each Business Day during which a Mortgage Loan shall have a
Mortgage Loan Suspension Code assigned to it, Purchaser shall send to Custodian
an Unidentified/Suspension Mortgage Loan Directive with respect to such Mortgage
Loan.

     (d) At any time following the delivery of a Certification, in the event
Custodian becomes aware of any defect with respect to such Submission Package or
the related forms, including the return of documents to the Custodian from
Takeout Investor due to a defect in such documents, the Custodian shall give
prompt oral notice of such defect to the Purchaser, followed by a written
specification thereof.

                 -------
under the Purchase Agreement or hereunder or in connection with the exercise by
Purchaser of any remedy pursuant to Section 3 of the Purchase Agreement then,
subject to the provisions of Section 3(c) hereof, Purchaser may, by notice to
Custodian, (a) appoint Custodian as its delegee to complete the endorsements on
the Mortgage Notes held by Custodian and to complete and record at Purchaser's
expense the related blank Assignments of Mortgages relating to the affected
Mortgage Loan in accordance with Purchaser's instructions and, when applicable,
and (b) require Custodian to deliver to Purchaser, Takeout Investor or Successor
Servicer the Submission Packages (or any portion thereof specified by Purchaser)
in Custodian's possession or under Custodian's control to which the failure
relates.

     Section 7.  Access to Documents.  Upon reasonable prior written notice to
                 -------------------
Custodian, Purchaser (and if the Mortgage Loans have been assigned, Assignee)
and its agents, accountants, attorneys and auditors will be permitted during
normal business hours to examine and copy at their expense the Submission
Packages, documents, records and other papers in possession of or under the
control of Custodian relating to any or all of the Mortgage Loans in which
Purchaser has an interest.  Upon the request of Purchaser (or, if applicable,
Assignee) and at the cost and expense of Purchaser (or, if applicable,
Assignee), Custodian shall provide such Purchaser (or, if applicable, Assignee)
with copies of the Mortgage Notes, Assignments

                                      13

                 ---------------------------------------------------------------
Care.  (a) It is understood that Seller will be charged for Custodian's fees for
----
its services under this Agreement in such amounts and in the manner set forth in
the related Purchase Agreement. Notwithstanding the foregoing, Custodian has no
lien on, and shall not attempt to place a lien on, any of the Mortgage Loans or
proceeds thereof to secure the payment of its fees.

     (b) Subject to the provisions of any other agreement between Custodian and
Purchaser, Custodian may only resign for cause. Such resignation shall take
effect upon the earlier of (i) the appointment of a successor Custodian by
Purchaser and delivery of all the Submission Packages and any portion of, the
related documents in Custodian's possession to the successor Custodian, and (ii)
the delivery of all the Submission Packages and any portion of the related
documents in Custodian's possession to the Purchaser or its designee pursuant to
(c) below.

     (c) In the event of any such resignation, Custodian shall promptly transfer
to the successor Custodian all Submission Packages and related documents in
Custodian's possession and the successor Custodian shall hold Submission
Packages and related documents in accordance with this Agreement.  If Purchaser
directs the removal of Custodian, Purchaser shall be responsible for all
expenses associated with the transfer of the Submission Packages and any related
documents in Custodian's possession and for any fee of the successor Custodian
in excess of the fees of the initial Custodian hereunder.  The Purchaser shall
have 90 days in which to appoint and designate an acceptable successor
Custodian.  If the Purchaser fails to appoint a successor Custodian within such
90-day period, then Custodian shall deliver possession and custody of the
Submission Packages and any related Submission Packages in Custodian's
possession to Purchaser at the address specified on the cover page hereof, or if
a timely written designation is received by Custodian, to any designee of
Purchaser.

     (d) Custodian shall have responsibility only for the Submission Packages
and the contents thereof which have been actually delivered to it and which have
not been released to Seller, Purchaser, the Agency or Assignee or their
respective agent or designee in accordance with this Agreement.  The standard of
care to be exercised by Custodian in the performance of its duties under this
Agreement shall be to exercise the same degree of care as Custodian exercises
when it holds mortgage loan documents as security for its own loans or its own
mortgage warehouse loan customers.  Custodian is an agent, bailee and custodian
only and is not intended to be, nor shall it be construed to be (except only as
agent, bailee and custodian), a representative, trustee or fiduciary of or for
either Seller, the Agency, Purchaser or Assignee.

     (e) Custodian shall incur no liability to any Entity for Custodian's acts
or omissions hereunder, except for liabilities which (i) arise from Custodian's
gross negligence or willful misconduct or (ii) solely with respect to the
Purchaser, which arise from Custodian negligently or intentionally failing to
(A) issue an accurate Certification Report, provided, however, any such
liability shall not be incurred with respect to the issuance of an inaccurate
Certification Report if the defect causing such inaccuracy would not have been
ascertainable by the Custodian applying

the procedures expressly set forth in this Agreement, (B) timely deliver the
Submission Package in accordance with the Delivery Instructions or Purchaser's
written instructions, as applicable, (C) prevent the loss, damage or destruction
of any document included in a Submission Package when held by Custodian, (D)
perform its obligations under Section 5 or (E) comply with an
Unidentified/Suspension Mortgage Loan Directive; provided, however, Custodian
shall have no liability hereunder if Custodian's failure to perform resulted
from the inaction or action of any other Entity, other than Entities that are
affiliated with Custodian or are acting under the direct control of Custodian.
Custodian's liability under this Agreement shall be limited to direct damages
resulting from aforesaid. In addition Custodian shall not be liable, directly or
indirectly, for any losses, claims, damages, liabilities or expenses which would
have been avoided had any Entity making a claim taken reasonable action to
mitigate such losses, claims, damages, liabilities or expenses or (2) special or
consequential damages, even if Custodian has been advised of the possibility of
such damages; provided, however, that Purchaser's direct damages resulting from
a decline in the market value of a Mortgage Loan shall not be deemed special or
consequential damages.

     (f) Custodian shall be entitled to rely upon the advice of its legal
counsel from time to time and shall not be liable for any action or inaction by
it in reliance upon such advice. Custodian also shall be entitled to rely upon
any notice, document, correspondence, request or directive received by it from
Seller, Takeout Investor, Purchaser or Assignee, as the case may be, that
Custodian believes to be genuine and to have been signed or presented by the
proper and duly authorized officer or representative thereof, and shall not be
obligated to inquire as to the authority or power of any person so executing or
presenting such documents or as to. the truthfulness of any statements set forth
therein.

     (g) Seller hereby indemnifies, defends and holds Custodian harmless from
and against any claim, legal action, liability or loss that is initiated against
or incurred by Custodian, including court costs and reasonable attorney's fees
and disbursements, in connection with Custodian's performance of its duties
under this Agreement, including those involving ordinary negligence, but
excluding those involving gross negligence or willful misconduct of Custodian.

     (h) Custodian undertakes to perform such duties and only such duties as are
specifically set forth in this Agreement, it being expressly understood that
there are no implied duties hereunder.

                 -----------------------
that Purchaser shall assign, as of the date of the purchase of all of its right,
title and interest in and to all Mortgage Loans purchased by Purchaser pursuant
to the Purchase Agreement and all rights of Purchaser under the Purchase
Agreement (and this Agreement) in respect of such Mortgage Loans represented
thereby to Assignee, subject only to an obligation on the part of Assignee to
deliver each such Mortgage Loan to Custodian or to Purchaser to permit
Custodian, Purchaser or its designee to make delivery thereof to Takeout
Investor, but not otherwise. Seller hereby irrevocably consents to such
assignment.  Assignment by Purchaser of the Mortgage Loans as provided in this
Section 9 shall not release Purchaser from its obligations otherwise under this
Agreement.  Subject to any limitations in any agreement between Assignee and
Purchaser, Assignee may, upon notice of Purchaser's default as provided in
Section 3(b) hereof, directly

                                      15
<PAGE>

enforce and exercise such rights under this Agreement that have been assigned or
pledged to it and, until otherwise notified by Assignee, Purchaser shall no
longer have any of such rights. Custodian shall assume that any assignment from
Purchaser to Assignee is subject to no limitations that are not expressly set
forth in this Agreement.

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

     (a)(1) Purchaser may, in its sole discretion, from time to time, purchase
one or more Mortgage Loans from Seller.  Seller shall be deemed to make for the
benefit of Purchaser, as of the applicable dates specified in Section 8, the
representations and warranties set forth in Section 8 in respect of each such
Mortgage Loan.

     (a)(2) Prior to Purchaser's election to purchase any Mortgage Loan,
Purchaser shall have received from Seller a Loan Purchase Detail, either
electronically or via a facsimile transmission, and Custodian shall have
received all applicable documents required by Section 2 of the Custodial
Agreement. The terms and conditions of such purchase shall be set forth in this
Agreement and in each Funding Confirmation.

     (b)(1) If Purchaser elects to purchase any Mortgage Loan, Purchaser shall
pay the amount of the Purchase Price for such Mortgage Loan by wire transfer of
immediately available funds (i) if a Warehouse Lender's Release has been
included in the related Conduit Submission Package, in accordance with the
Warehouse Lender's Wire Instructions or (ii) if there is no Warehouse Lender's
Release included in the related Conduit Submission Package, in accordance with
the Seller's Wire Instructions.  If Purchaser is the Warehouse Lender with
respect to a Mortgage Loan, the amount transferred shall be reduced to account
for amounts previously advanced by Purchaser with respect to such Mortgage Loan.
With respect to each Mortgage Loan which Purchaser has elected to purchase,
Custodian shall deliver to Takeout Investor the applicable portion of the
Conduit Submission Package, in the manner and at the time set forth in the
Custodial Agreement. Seller shall thereafter promptly deliver to Takeout
Investor any and all additional documents requested by Takeout Investor to
enable Takeout Investor to make payment to Purchaser of the Takeout Proceeds.

     (b)(2) Simultaneously with the payment by Purchaser of the Purchase Price
of a Mortgage Loan, in accordance with the Warehouse Lender's Wire Instructions
or the Seller's Wire Instructions, as applicable, with respect to a Mortgage
Loan, Seller hereby conveys to Purchaser all of Seller's right, title and
interest in and to, such Mortgage Loan, free and clear of any lien, claim or
encumbrance.

     (c)    With respect to each Mortgage Loan that Purchaser elects to purchase
hereunder, Purchaser shall owe to Seller a Performance Fee.  The Yield
Compensation Adjustment component of the Performance Fee shall include an
accrued interest calculation. Purchaser's

                                       6
<PAGE>

accrued interest calculation shall be identical to that of Takeout Investor,
therefore the amount of accrued interest included in a settlement calculation
will represent accrued interest paid to Purchaser and paid by Purchaser.

     (d)    Notwithstanding the satisfaction by Seller of the conditions
specified in Section 2(a), Purchaser is not obligated to purchase any Mortgage
Loan offered to it hereunder. In the event that Purchaser rejects a Mortgage
Loan for purchase for any reason and/or does not transmit the Purchase Price,
any Conduit Submission Package delivered to Custodian in anticipation of such
purchase shall be returned by Custodian in accordance with the terms of the
bailee letter under which it was received.

     Section 3.  Sale of Mortgage Loans to Takeout Investor.
                 ------------------------------------------

     (a)(1) Upon the sale to Takeout Investor of a Mortgage Loan previously
purchased by Purchaser hereunder, Seller shall cause Takeout Proceeds relating
to such Mortgage Loan to be paid to Purchaser in accordance with Purchaser's
Wire Instructions to Seller.

     (a)(2) All Takeout Proceeds received by Purchaser from Takeout Investor
after 3:00 P.M. New York City time on a Business Day (or at any time on a day
which is not a Business Day) shall be deemed, with regard to determining the
Settlement Date, received by Purchaser on the next succeeding Business Day.

     (b)(1) If any Mortgage Loan is rejected by Takeout Investor because it is a
Defective Mortgage Loan, Seller shall promptly notify Purchaser. If any Mortgage
Loan is a Defective Mortgage Loan on the Purchase Date and in Purchaser's sole
judgement the defects in such Mortgage Loan will not be cured (or in fact are
not cured) by Seller prior to the Commitment Expiration Date, the Pass-Through
Rate applicable to such Defective Mortgage Loan shall, on such Commitment
Expiration Date, increase by the Incremental Pass-Through Rate and Purchaser, at
its election, may require that Seller, upon receipt of notice from Purchaser,
immediately repurchase Purchaser's ownership interest in such Defective Mortgage
Loan by remitting to Purchaser (in immediately available funds in accordance
with Purchaser's instructions) the amount paid by Purchaser for such Defective
Mortgage Loan plus interest at the Pass-Through Rate on the principal amount
thereof from the Purchase Date of such Mortgage Loan to the date of such
repurchase.  If at any time prior to the repurchase of a Defective Mortgage Loan
by Seller or the purchase of a Mortgage Loan by Takeout Investor, Seller
receives the Mortgage Note or any other portion of the Conduit Submission
Package, Seller shall promptly forward such Mortgage Note and/or other portion
of the Conduit Submission Package to Purchaser.

     (b)(2) If Seller fails to comply with its obligations in the manner
described in Section 3(b)(1), upon receipt by Seller of notice from Purchaser,
Seller's rights and obligations to service Mortgage Loans, as provided in this
Agreement, shall terminate.  If an Act of Insolvency occurs at any time,
Seller's rights and obligations to service the Mortgage Loans, as provided in
this Agreement, shall terminate immediately, without any notice or action by
Purchaser. Upon any such termination, Purchaser is hereby authorized and
empowered as the exclusive agent for Seller to sell and transfer such rights to
service the Mortgage Loans for such price and on such terms and conditions as
Purchaser shall reasonably determine, and Seller shall not otherwise

                                       7
<PAGE>

attempt to sell or transfer such rights to service without the prior consent of
Purchaser. Seller shall perform all acts and take all action so that all files
and documents relating to the Mortgage Loans held by Seller, together with all
escrow amounts relating to such Mortgage Loans, are delivered to Successor
Servicer. To the extent that the approval of a Third Party Underwriter or any
other person is required for any such sale or transfer, Seller shall fully
cooperate with Purchaser to obtain such approval. Upon exercise by Purchaser of
its remedies under this Section 3(b)(2), Seller hereby authorizes Purchaser to
receive all amounts paid by any purchaser of such rights to service the Mortgage
Loans and to remit such amounts to Seller subject to Purchaser's rights of set-
off under this Agreement. Upon exercise by Purchaser of its remedies under this
Section 3(b)(2), Purchaser's obligation to pay and Seller's right to receive any
portion of the Performance Fee relating to such Mortgage Loans shall
automatically be canceled and become null and void, provided that such
cancellation shall in no way relieve Seller or otherwise affect the obligation
of Seller to indemnify and hold Purchaser harmless as specified in Section 3(c).

     (b)(3) Each Mortgage Loan required to be delivered to Successor Servicer by
Section 3(b)(2) shall be delivered free of any servicing rights in favor of
Seller and free of any title, interest, lien, encumbrance or claim of any kind
of Seller.  Seller shall deliver or cause to be delivered all files and
documents relating to each Mortgage Loan held by Seller to Successor Servicer.
Seller shall promptly take such actions and furnish to Purchaser such documents
that Purchaser deems necessary or appropriate to enable Purchaser to cure any
defect in each such Mortgage Loan or to enforce such Mortgage Loans, as
appropriate.

     (c)    Seller agrees to indemnify and hold Purchaser and its assignees
harmless from and against all Losses resulting from or relating to any breach or
failure to perform by Seller of any representation, warranty, covenant, term or
condition made or to be performed by Seller under this Agreement.

     (d)    No exercise by Purchaser of its rights under this Section 3 shall
relieve Seller of responsibility or liability for any breach of this Agreement.

     (e)    Seller hereby grants Purchaser a right of set-off against the
payment of any amounts that may be due and payable to Purchaser from Seller,
such right to be upon any and all monies or other property of Seller held or
received by Purchaser, or due and owing from Purchaser to Seller.

     Section 4.  Servicing of the Mortgage Loans.
                 -------------------------------

     (a)    Seller shall service and administer each Mortgage Loan on behalf of
Purchaser in accordance with prudent mortgage loan servicing standards and
procedures generally accepted in the mortgage banking industry and in accordance
with the requirements of Takeout Investor as though Takeout Investor's
requirement were set forth in independent contract between Seller and Purchaser,
provided that Seller shall at all times comply with applicable law, and the
requirements of any applicable insurer or guarantor so that the insurance in
respect of any Mortgage Loan is not voided or reduced. Seller shall at all times
maintain accurate and complete records of its servicing of each Mortgage Loan,
and Purchaser may, at any time during Seller's business hours on reasonable
notice, examine and make copies of such records.  In addition, if a Mortgage
Loan is not purchased by Takeout Investor on or before the Commitment Expiration

                                       8
<PAGE>

Date, Seller shall at Purchaser's request deliver to Purchaser monthly reports
regarding the status of such Mortgage Loan, which reports shall include, but
shall not be limited to, a description of each Mortgage Loan in default for more
than thirty days, and such other circumstances with respect to any Mortgage Loan
(whether or not such Mortgage Loan is included in the foregoing list) that could
materially adversely affect any such Mortgage Loan, Purchaser's ownership of any
such Mortgage Loan or the collateral securing any such Mortgage Loan. Seller
shall deliver such a report to Purchaser every thirty days until (i) the
purchase by Takeout Investor of such Mortgage Loan pursuant to the related
Takeout Commitment or (ii) the exercise by Purchaser of any remedial election
pursuant to Section 3.

     (b)    Within five Business Days of notice from Purchaser or, with respect
to any Mortgage Loan, on the Commitment Expiration Date, Seller shall establish
and maintain a Custodial Account entitled "[name of Seller], in trust for Paine
Webber Real Estate Securities Inc. and its assignees under the Mortgage Loan
Purchase Agreement dated [the date of this Agreement]" and shall promptly
deposit into such Custodial Account, in the form received with any necessary
endorsements, all collections received in respect of each Mortgage Loan that are
payable to Purchaser as the owner of each such Mortgage Loan.

     (c)    Amounts deposited in the Custodial Account with respect to any
Mortgage Loan shall be held in trust for Purchaser as the owner of such Mortgage
Loan and shall be released only as follows:

            (1)  Except as otherwise provided in this Section 4(c), following
     receipt by Purchaser or its designee of the Takeout Proceeds for such
     Mortgage Loan from Takeout Investor or Seller amounts deposited in the
     Custodial Account shall be paid in accordance with Section 2(c).
     Notwithstanding the foregoing, all amounts deposited in the Custodial
     Account shall be paid to Seller upon the purchase by Takeout Investor of
     the related Mortgage Loan(s) from Purchaser if, and to the extent that, the
     amounts due and payable to Purchaser hereunder have been set off against
     the Purchase Price for the Mortgage Loan or the Performance Fee relating to
     the Mortgage Loan. The amounts paid to Seller (if any) pursuant to this
     Section 4(c)(1) shall constitute Seller's sole compensation for servicing
     the Mortgage Loans as provided in this Section 4.

            (2)  If Successor Servicer is appointed by Purchaser (either under
     the circumstances set forth in Section 3 or otherwise), all amounts
     deposited in the Custodial Account shall be paid to Purchaser promptly upon
     such delivery.

            (3)  If a Mortgage Loan is not purchased by Takeout Investor on or
     before the Commitment Expiration Date, during the period thereafter that
     Seller remains as servicer, all amounts deposited in the Custodial Account
     shall be released only in accordance with a Purchaser's written
     instructions.

     Section 5.  Trade Assignments.  Seller hereby assigns to Purchaser, free of
                 -----------------
any security interest, lien, claim or ,encumbrance of any kind, Seller's rights,
under each Takeout Commitment to the full extent permitted by Takeout Investor,
to deliver the Mortgage Loan(s) specified therein to Takeout Investor and to

not be deemed to have accepted such rights of Seller which relate to a

                                       9

particular Mortgage Loan unless and until it purchases the Mortgage Loan, and
nothing set forth herein shall be deemed to impair Purchaser's right to reject
any Mortgage Loan for any reason, in its sole discretion.

     Section 6.  Transfers of Mortgage Loans by Purchaser.  Purchaser may, in
                 ----------------------------------------
its sole discretion, assign all of its right, title and interest in or grant a
security interest in any Mortgage Loan sold by Seller hereunder and all rights
of Purchaser under this Agreement and the Custodial Agreement, in respect of
such Mortgage Loan to Assignee, subject only to an obligation on the part of
Assignee to deliver each such Mortgage Loan to Takeout Investor pursuant to
Section 5 or to Purchaser to permit Purchaser or its designee to make delivery
thereof to Takeout Investor pursuant to Section 5.  It is anticipated that such
assignment to Assignee will be made by Purchaser, and Seller hereby irrevocably
consents to such assignment.  No notice of such assignment shall be given by
Purchaser to Seller or Takeout Investor.  Assignment by Purchaser of the
Mortgage Loans as provided in this Section 6 shall not release Purchaser from
its obligations otherwise under this Agreement.

     Without limitation of the foregoing, an assignment of a Mortgage Loan to
Assignee, as described in this Section 6, shall be effective upon delivery to
Assignee of a Conduit Submission Package.

     Section 7.  Record Title to Mortgage Loans; Intent of Parties; Security

Interest.
--------

     (a)   From and after the delivery of the related Conduit Submission
Package, and subject to the remedies of Purchaser in Section 3, Seller shall
remain the last named payee or endorsee of each Mortgage Note and the mortgagee
or assignee of record of each Mortgage in trust for the benefit of Purchaser,
for the sole purpose of facilitating the servicing of such Mortgage Loan.

     (b)   Seller shall maintain a complete set of books and records for each
Mortgage Loan which shall be clearly marked to reflect the ownership interest in
each Mortgage Loan of Purchaser.

     (c)   Purchaser and Seller confirm that the transactions contemplated
herein are intended to be sales of the Mortgage Loans by Seller to Purchaser
rather than borrowings secured by the Mortgage Loans. In the event, for any
reason, any transaction is construed by any court or regulatory authority as a
borrowing rather than as a sale, the Seller and Purchaser intend that Purchaser
or Assignee, as the case may be, shall have a perfected first priority security
interest in the Collateral, free and clear of adverse claims. In such case,
Seller shall be deemed to have hereby granted to Purchaser or Assignee, as the
case may be, a first priority security interest in and lien upon the Collateral,
free and clear of adverse claims. In such event, this Agreement shall constitute
a security agreement, the Custodian shall be deemed to be an independent
custodian for purposes of perfection of the security interest granted to
Purchaser or Assignee, as the case may be, and Purchaser or Assignee, as the
case may be, shall have all of the rights of a secured party under applicable
law. Seller shall, not later than the date of the first purchase of a Mortgage
Loan by Purchaser under this Agreement, deliver to Purchaser a UCC-1 Financing
Statement, executed by Seller, containing a description of collateral in the
form attached hereto in Exhibit E.

     Section 8.  Representations and Warranties.
                 ------------------------------

     (a)  Seller hereby represents and warrants to Purchaser as of the date
hereof and as of the date of each delivery of a Conduit Submission Package that:

          (i)    Seller is duly organized, validly existing and in good standing
     under the laws of the state of its organization or of the United States of
     America and has all licenses necessary to carry on its business as now
     being conducted and is licensed, qualified and in good standing in the
     state where the Mortgaged Property is located if the laws of such state
     require licensing or qualification in order to conduct business of the type
     conducted by Seller.  Seller has all requisite power and authority
     (including, if applicable, corporate power) to execute and deliver this
     Agreement and to perform in accordance herewith; the execution, delivery
     and performance of this Agreement (including all instruments of transfer to
     be delivered pursuant to this Agreement) by Seller and the consummation of
     the transactions contemplated hereby have been duly and validly authorized;
     this Agreement evidences the valid, binding and enforceable obligation of
     Seller; and all requisite action (including, if applicable, corporate
     action) has been taken by Seller to make this Agreement valid and binding
     upon Seller in accordance with its terms;

          (ii)   No approval of the transactions contemplated by this Agreement
     from the OTS, the NCUA, the FDIC or any similar federal or state regulatory
     authority having jurisdiction over Seller is required, or if required, such
     approval has been obtained.  There are no actions or proceedings pending or
     affecting Seller which would adversely affect its ability to perform
     hereunder.  The transfers, assignments and conveyances provided for herein
     are not subject to the bulk transfer or any similar statutory provisions in
     effect in any applicable jurisdiction;

          (iii)  The consummation of the transactions contemplated by this
     Agreement are in the ordinary course of business of Seller and will not
     result in the breach of any term or provision of the charter or by-laws of
     Seller or result in the breach of any term or provision of, or conflict
     with or constitute a default under or result in the acceleration of any
     obligation under, any agreement, indenture or loan or credit agreement or
     other instrument to which Seller or its property is subject, or result in
     the violation of any law, rule, regulation, order, judgment or decree to
     which Seller or its property is subject;

          (iv)   This Agreement, the Custodial Agreement and every document to
     be executed by Seller pursuant to this Agreement is and will be valid,
     binding and subsisting obligations of Seller, enforceable in accordance
     with their respective terms. No consents or approvals are required to be
     obtained by Seller or its Parent Company for the execution, delivery and
     performance of this Agreement or the Custodial Agreement by Seller;

          (v)    Purchaser will be the sole owner of the related Mortgage Loan,
     free and clear of any lien, claim or encumbrance; and

          (vi)   All information relating to Seller that Seller has delivered or
     caused to be delivered to Purchaser, including, but not limited to, all
     documents related to this

                                      11
<PAGE>

     Agreement, the Custodial Agreement or Seller's financial statements, does
     not contain any untrue statement of a material fact or omit to state a
     material fact necessary to make the statements made therein or herein in
     light of the circumstances under which they were made, not misleading; and

          (vii)  There is no action, suit, proceeding, inquiry or investigation,
     at law or in equity, or before, or by any court, public board or body
     pending or, to Seller's knowledge, threatened against or affecting Seller
     (or, to Seller's knowledge, any basis therefor) wherein an unfavorable
     decision, ruling or finding would adversely affect the validity of
     enforceability of this Agreement, the Custodial Agreement or any agreement
     or instrument to which Seller is a party and which is used or contemplated
     for use in the consummation of the transactions contemplated hereby, would
     adversely affect the proceedings of Seller in connection herewith or would
     or could materially and adversely affect Seller's ability to carry out its
     obligations hereunder.

     (b)  Seller hereby represents, warrants and covenants to Purchaser with
respect to each Mortgage Loan as of the related Purchase Date that:

          (i)    The Mortgage Loan conforms in all respects to the requirements
     of this Agreement, the Commitment Requirements and all other requirements
     of Takeout Investor;

          (ii)   Seller is the sole owner and holder of the Mortgage Loan free
     and clear of any and all liens, claims, defenses, offsets, pledges,
     encumbrances, charges or security interests of any nature and has full
     right and authority, subject to no interest or participation of, or
     agreement with, any other party, to sell and assign the same pursuant to
     this Agreement;

          (iii)  Except for sub-servicing agreements with Dovenmuehle Mortgage,
     Inc. affecting said Mortgage Loans relating to sub-servicing for Seller,
     Purchaser and Takeout Investor, no servicing agreement has been entered
     into with respect to the Mortgage Loan, or any such servicing agreement has
     been terminated and there are no restrictions, contractual or governmental,
     which would impair the ability of Purchaser or Purchaser's designees from
     servicing the Mortgage Loan;

          (iv)   The Mortgage is a valid and subsisting first lien on the
     property therein described and the Mortgaged Property is free and clear of
     all encumbrances and liens having priority over the first lien of the
     Mortgage except for liens for real estate taxes and special assessments not
     yet due and payable. Any pledge account, security agreement, chattel
     mortgage or equivalent document related to, and delivered to Purchaser with
     the Mortgage, establishes in Seller a valid and subsisting first lien on
     the property described therein, and Seller has full right to sell and
     assign the same to Purchaser;

          (v)    Neither Seller nor any prior holder of the Mortgage has
     modified the Mortgage in any material respect; satisfied, canceled or
     subordinated the Mortgage in whole or in part; released the Mortgaged
     Property in whole or in part from the lien of the Mortgage; or executed any
     instrument of release, cancellation, modification or

                                      12
<PAGE>

     satisfaction unless such release, cancellation, modification or
     satisfaction does not adversely affect the value of the Mortgage Loan and
     is contained in the related Document File;

          (vi)   The Mortgage Loan is not in default, and all Monthly Payments
     due prior to the Purchase Date and all taxes, governmental assessments,
     insurance premiums, water, sewer and municipal charges (but only to the
     extent that such water, sewer and municipal charges constitute a lien on
     the Mortgaged Property), leasehold payments or ground rents have been paid.
     Seller has not advanced funds, or induced or solicited any advance of funds
     by a party other than the Mortgagor directly or indirectly, for the payment
     of any amount required by the Mortgage Loan. The collection practices used
     by each entity which has serviced the Mortgage Loan have been in all
     respects legal, proper, prudent, and customary in the mortgage servicing
     business. With respect to escrow deposits and payments in those instances
     where such were required, there exist no deficiencies in connection
     therewith for which customary arrangements for repayment thereof have not
     been made and no escrow deposits or payments or other charges or payments
     have been capitalized under any Mortgage or the related Mortgage Note;

          (vii)  There is no default, breach, violation or event of acceleration
     existing under the Mortgage or the related Mortgage Note and no event
     which, with the passage of time or with notice and the expiration of any
     grace of cure period, would constitute a default, breach, violation or
     event of acceleration; and Seller has not waived any default, breach,
     violation or event of acceleration;

          (viii) The Mortgage Loan is not subject to any right of rescission,
     set-off, counterclaim or defense, including the defense of usury, nor will
     the operation of any of the terms of the Mortgage Note or the Mortgage, or
     the exercise of any right thereunder, render either the Mortgage Note or
     the Mortgage unenforceable, in whole or in part, or subject to any right of
     rescission, set-off, counterclaim or defense, including the defense of
     usury, and no such right of rescission, set-off, counterclaim or defense
     has been asserted with respect thereto;

          (ix)   The Mortgage Note and the related Mortgage are genuine and each
     is the legal, valid and binding obligation of the maker thereof,
     enforceable in accordance with its terms.  All parties to the Mortgage Note
     and the Mortgage had legal capacity to execute the Mortgage Note and the
     Mortgage and each Mortgage Note and Mortgage have been duly and property
     executed by the Mortgagor.  No Mortgagor is a partnership, trust or
     corporation;

          (x)    The Mortgage Loan meets, or is exempt from, applicable state or
     federal laws, regulations and other requirements pertaining to usury, and
     the Mortgage Loan is not usurious;

          (xi)   Any and all requirements of any federal, state or local law
     including, without limitation, truth-in-lending, real estate settlement
     procedures, consumer credit protection, equal credit opportunity or
     disclosure laws applicable to the Mortgage Loan

                                      13
<PAGE>

     have been complied with, and Seller shall deliver to Purchaser upon demand,
     evidence of compliance with all such requirements;

          (xii)    Either: (i) Seller and every other holder of the Mortgage, if
     any, were authorized to transact and do business in the jurisdiction in
     which the Mortgaged Property is located at all times when such party held
     the Mortgage; or (ii) the loan of mortgage funds, the acquisition of the
     Mortgage (if Seller was not the original lender), the holding of the
     Mortgage and the transfer of the Mortgage did not constitute the
     transaction of business or the doing of business in such jurisdiction;

          (xiii)   The Mortgage Loan has closed and the proceeds of the Mortgage
     Loan have been fully disbursed; provided that, with respect to Mortgage
     Loans originated within the previous 120 days, alterations and repairs with
     respect to the Mortgaged Property or any part thereof may have required an
     escrow of funds in an amount sufficient to pay for all outstanding work
     within 120 of the origination of the Mortgage Loan, and if so, such funds
     are held in escrow by Seller, a title company or other escrow agent;

          (xiv)    The related Mortgage contains customary and enforceable
     provisions such as to render the rights and remedies of the holder thereof
     adequate for the realization against the Mortgaged Property of the benefits
     of the security, including, (i) in the case of a Mortgage designated as a
     deed of trust, by trustee's sale, (ii) in the case of a Mortgage designated
     as a security deed, by non-judicial sale, (iii) in the case of a Mortgage
     designated as any other instrument which provides for enforcement by a non
     judicial sale, by non-judicial sale, and (iv) otherwise by judicial
     foreclosure;

          (xv)     The Mortgage Loan was originated free of any "original issue
     discount" with respect to which the owner of the Mortgage Loan could be
     deemed to have income pursuant to Sections 1271 et seq. the Internal
                                                     -- ---
     Revenue Code;

          (xvi)    Each Mortgage Loan was originated by an institution that is
     eligible to issue Mortgage Loans under the Applicable Guide;

          (xvii)   At origination, the Mortgaged Property was free and clear of
     all mechanics' and materialmen's liens or liens in the nature thereof which
     are or could be prior to the Mortgage lien, and no rights are outstanding
     that under law could give rise to any such lien;

          (xviii)  Either (i) all improvements which were considered in
     determining the Appraised Value of the Mortgaged Property lay wholly within
     the boundaries and building restriction lines of the Mortgaged Property,
     and no improvements on adjoining properties encroach upon the Mortgaged
     Property or (ii) the short form title insurance policy insures against loss
     or damage resulting from any encroachments of boundary lines affecting the
     Mortgaged Property;

          (xix)    As of the Closing Date the Mortgaged Property is lawfully
     occupied under applicable law. All inspections, licenses and certificates
     required to be made or issued

                                      14

<PAGE>

     with respect to all occupied portions of the Mortgaged Property and, with
     respect to the use and occupancy of the same, including but not limited to
     certificates of occupancy and fire underwriting certificates, have been
     made or obtained from the appropriate authorities. The Mortgagor
     represented at the time of origination of the Mortgage Loan that the
     Mortgagor would occupy the Mortgaged Property as the Mortgagor's primary
     residence (except as may be otherwise permitted by the terms hereof);

          (xx)     There is no proceeding pending for the total or partial
     condemnation of the Mortgaged Property and said property is undamaged by
     waste, fire, earthquake or earth movement, windstorm, flood, tornado or
     other casualty;

          (xxi)    All buildings upon the Mortgaged Property are insured against
     loss by fire, hazards of extended coverage and such other hazards as are
     customary in the area where the Mortgaged Property is located, pursuant to
     fire and hazard insurance policies with extended coverage or other
     insurance required by the Applicable Purchase Agreement, in an amount at
     least equal to the greater of (i) the outstanding principal balance of the
     Mortgage Loan or (ii) the maximum insurable value (replacement cost without
     deduction for depreciation) of the improvements constituting the Mortgaged
     Property. If applicable laws limit the amount of such insurance to the
     replacement cost of the improvements constituting the Mortgaged Property or
     to some other amount, then such insurance is in an amount equal to the
     maximum allowed by such laws. Such insurance amount is sufficient to
     prevent the Mortgagor or the loss payee under the policy from becoming
     a co-insurer. The insurer issuing such insurance is acceptable pursuant to
     the Applicable Purchase Agreement. All individual insurance policies
     contain a standard mortgagee clause naming Seller, its successors and
     assigns, as mortgagee and all premiums thereon have been paid. Each
     Mortgage obligates the Mortgagor thereunder to maintain all such insurance
     at Mortgagor's cost and expense, and upon the Mortgagor's failure to do so,
     authorizes the holder of the Mortgage to obtain and maintain such insurance
     at Mortgagor's cost and expense and to seek reimbursement therefor from the
     Mortgagor. Any flood insurance required by applicable law has been
     obtained;

          (xxii)   The related Mortgage Note is payable on the Due Date of each
     month in self-amortizing monthly installments of principal and interest,
     with interest payable in arrears, providing for full amortization by
     maturity, over an original term of not more than thirty years;

          (xxiii)  At the time that the related Mortgage Loan was made the
     Mortgagor represented that the Mortgagor would occupy such Mortgaged
     Property as Mortgagor's primary residence;

          (xxiv)   The Mortgaged Property consists of a single parcel of real
     property;

          (xxv)    There are no circumstances or conditions with respect to the
     Mortgage, the Mortgaged Property, the Mortgagor or the Mortgagor's credit
     standing that can be reasonably expected to cause Takeout Investor or
     private institutional investors to regard the Mortgage Loan as an
     unacceptable investment, cause the Mortgage Loan to become delinquent or
     adversely affect the value or marketability of the Mortgage Loan;

                                      15

<PAGE>

          (xxvi)   The Document File contains or shall contain prior to the
     Commitment Expiration Date each of the documents and instruments specified
     to be included therein duly executed and in due and proper form and each
     such document or instrument is in form acceptable to Takeout Investor. Each
     Mortgage Note and Mortgage are on forms approved by Takeout Investor; and

          (xxvii)  Each Mortgage Loan is covered by a mortgage title insurance
     policy acceptable to Takeout Investor, issued by, and the valid and binding
     obligation of, a title insurer acceptable to Takeout Investor, and
     qualified to do business in the jurisdiction where the property subject to
     the Mortgage is located; insuring Seller, its successors and assigns, as to
     the first priority lien of the Mortgage in the original principal amount of
     the Mortgage Loan. The originating lender is the named insured and the sale
     insured of such mortgage title insurance policy, the assignment to
     Purchaser of Seller's interest in such mortgage title insurance policy does
     not require the consent of or notification to the insurer, such mortgage
     title insurance policy is in full force and effect and will be in full
     force and effect and inure to the benefit of Purchaser upon the
     consummation of the transactions contemplated by this Agreement and no
     claims have been made under such mortgage title insurance policy and no
     prior holder of the related Mortgage, including Seller, has done, by act or
     omission, anything which would impair the coverage of such mortgage title
     insurance policy.

          (xxviii) The loan-to-value ratio of each Mortgage Loan does not exceed
     the maximum loan-to-value ratio permitted by the Applicable Guide. All
     provisions of each related primary mortgage insurance policy have been and
     are being complied with, and such policy is written with a private mortgage
     insurance company acceptable to the Takeout Investor, is the binding
     obligation of such insurer, is in full force and effect, and all premiums
     due thereunder have been paid. Seller has not engaged in any act or
     omission, and Seller has no knowledge of any act or omission by or on
     behalf of the related Mortgagor or any other person, which act or omission
     would impair the coverage or validity of any such primary mortgage
     insurance policy, the benefit of the endorsement provided for in the
     Applicable Guide, or the validity or binding effect of either. Any Mortgage
     Loan subject to a primary mortgage insurance policy obligates the Mortgagor
     thereunder to maintain such primary mortgage insurance policy and to pay
     all premiums and charges in connection therewith. The interest rate for the
     Mortgage Loan is net of any such insurance premiums.

     The representations and warranties of Seller in this Section 8 are
unaffected by and supersede any provision in any endorsement of any Mortgage
Loan or in any assignment with respect to such Mortgage Loan to the effect that
such endorsement or assignment is without recourse or without representation or
warranty. With respect to each Mortgage Loan purchased by Purchaser hereunder,
to the extent that any representation or warranty made by Seller is either not
required by Takeout Investor or is waived by Takeout Investor, Purchaser hereby
agrees to waive such representation or warranty if such Mortgage Loan is
purchased by Takeout Investor from Purchaser, in accordance with the terms of
the related Takeout Commitment.

     Section 9.  Covenants of Seller.  Seller hereby covenants and agrees with
                 -------------------
