(h)   In no event shall a Transaction be entered into when any Default or Event
      of Default has occurred and is continuing or when the Repurchase Date for
      such Transaction would be later than the Termination Date.

(i)   With respect to each Eligible Asset that is not a Wet-Ink Mortgage Loan,
      Seller shall deliver to Custodian the Mortgage File pertaining to each
      Eligible Asset to be purchased by Buyer no later than the time set forth
      in the Custodial and Disbursement Agreement.

(j)   With respect to each Eligible Asset that is not a Wet-Ink Mortgage Loan,
      pursuant to the Custodial and Disbursement Agreement, Custodian shall
      deliver to Buyer and Seller an Asset Schedule and Exception Report with
      respect to the Eligible Assets which Seller has

                                      -23-
<PAGE>

      requested Buyer purchase on such Purchase Date, and no later than 5 p.m.,
      New York City time, on each Purchase Date, Custodian shall deliver to
      Buyer a Trust Receipt in respect of all such Eligible Assets purchased by
      Buyer on such Purchase Date. Subject to the provisions of this Section 3
      and Section 11 of the Custodial and Disbursement Agreement, the Purchase
      Price for each Eligible Asset that is not a Wet-Ink Mortgage Loan will be
      made available to Seller by Disbursement Agent transferring, the aggregate
      amount of such Purchase Price in accordance with the Custodial and
      Disbursement Agreement.

(k)   With respect to each Eligible Asset that is a Wet-Ink Mortgage Loan, at
      the request of Buyer, Seller shall cause the Settlement Agent to send the
      Custodian a facsimile of the associated Escrow Instruction Letter on each
      Purchase Date. Subject to the provisions of this Section 3 and Section 8
      of the Custodial and Disbursement Agreement, the Purchase Price for each
      Eligible Asset which is a Wet-Ink Mortgage Loan will then be made
      available to Seller by Disbursement Agent transferring the aggregate
      amount of such Purchase Price in accordance with the Custodial and
      Disbursement Agreement. Seller shall deliver the Mortgage File related
      thereto and, to the extent requested by Buyer, the original Escrow
      Instruction Letter to Custodian, for receipt by Custodian no later than
      eight (8) Business Days following the Purchase Date.

(l)   Seller may repurchase Purchased Assets without penalty or premium, but
      subject to the last sentence of this Section 3(l), on any date. The
      Repurchase Price payable for the repurchase of any such Purchased Asset
      shall be reduced as provided in Section 5(d). If Seller intends to make
      such a repurchase, Seller shall give one (1) Business Day's prior written
      notice thereof to Buyer, designating the Purchased Assets to be
      repurchased. If such notice is given, the amount specified in such notice
      shall be due and payable on the date specified therein, and, on receipt,
      such amount shall be applied to the Repurchase Price for the designated
      Purchased Assets. The amount of the original Purchase Price of the
      Purchased Assets thus repurchased shall be available for subsequent
      Transactions subject to the terms of this Agreement. If any Purchased
      Asset is repurchased on any date other than the Repurchase Date for such
      Transaction, Seller shall pay to Buyer any amount determined by Buyer, in
      its sole discretion, as necessary to compensate Buyer for any additional
      losses, costs or expenses which it may reasonably incur as a result of
      such repurchase, including, without limitation, any loss, cost or expense
      incurred by reason of the liquidation or reemployment of deposits or other
      funds acquired by Buyer to fund or maintain such Transaction.

(m)   At the request of Seller made at least 90 days, but in no event earlier
      than 120 days, prior to the then current Termination Date, Buyer may in
      its sole discretion extend the Termination Date for a period of 364
      additional days or such other period to be determined by Buyer in its sole
      discretion by giving written notice of such extension to Seller no later
      than sixty (60) days after Buyer's receipt of Seller's request. Any
      failure by Buyer to deliver such notice of extension shall be deemed to be
      Buyer's determination not to extend the then current Termination Date.

(n)   Seller agrees to pay to Buyer the Non-Use Fee, in each case payable
      quarterly in arrears on the first Business Day following each quarterly
      anniversary of the Effective Date and

                                      -24-
<PAGE>

      on the Termination Date, commencing on October 29, 2004, such payment to
      be made in Dollars, in immediately available funds, without deduction,
      set-off or counterclaim, to Buyer at the account set forth in Section 8(a)
      hereof.

(o)   On any day on which the Margin Base exceeds the aggregate outstanding
      Purchase Price of all Transactions, so long as no Default or Event of
      Default has occurred and is continuing:

      (1)   Seller may prepare a Request for Additional Transactions for Excess
            Margin in the form of Exhibit VIII attached hereto ("Request for
            Additional Transactions for Excess Margin"), (A) specifying (i) the
            increase in Purchase Price for all outstanding Transactions and the
            requested Purchase Date, (ii) the Excess Margin with respect to all
            outstanding Transactions before giving effect to the requested
            Transaction, (iii) the remaining Excess Margin after giving effect
            to the requested Transaction, and (iv) the aggregate outstanding
            Purchase Price of the Transactions after giving effect to the
            requested Transaction, and (B) including a certification that, upon
            the consummation of the additional Transactions, the Margin Base
            will be equal to or greater than the aggregate outstanding Purchase
            Price of all Transactions, and the excess of the Margin Base over
            the aggregate outstanding Purchase Price, after giving effect to the
            Transaction, shall be the "Excess Margin".

      (2)   Seller shall transmit via Electronic Transmission the Request for
            Additional Transactions for Excess Margin to Disbursement Agent and
            Buyer prior to 12:00 noon, New York City time, on the requested
            Purchase Date. Upon confirming that the Request for Additional
            Transactions for Excess Margin correctly reflects the information
            set forth in Section 3(o)(1) and that, after giving effect to the
            requested Transaction, the amount of the Margin Base would be equal
            to or greater than the aggregate outstanding Purchase Prices of all
            Transactions, Buyer shall remit or cause Disbursement Agent to remit
            the additional Purchase Price in the amount set forth in such
            Request for Additional Transactions for Excess Margin and send a
            revised Confirmation with respect to such Purchased Assets. In the
            event that Buyer's assessment of the Margin Base would alter the
            information set forth in any Request for Additional Transactions for
            Excess Margin, Buyer shall promptly notify Seller in writing of such
            assessment.

      (3)   Buyer shall not be obligated to remit or cause Disbursement Agent to
            remit the additional Purchase Price requested pursuant to a Request
            for Additional Transactions for Excess Margin which (i) Buyer
            reasonably determines is based on erroneous information or would
            result in a Transaction other than in accordance with the terms of
            this Agreement, or (ii) does not reflect Buyer's current
            determination of Market Value as provided in the definition thereof.

                                      -25-

4.    MARGIN AMOUNT MAINTENANCE

(a)   If at any time the Margin Base is less than the aggregate Purchase Price
      for all outstanding Transactions (a "Margin Deficit"), then Buyer may by
      notice to Seller (as such notice is more particularly set forth below, a
      "Margin Deficit Notice") require Seller to transfer to Buyer or its
      designee (including Custodian) cash to be applied to reduce the Purchase
      Price with respect to all outstanding Transactions such that the aggregate
      Asset Value of the Purchased Assets will thereupon equal or exceed the
      aggregate Purchase Price for all outstanding Transactions. If Buyer
      delivers a Margin Deficit Notice to Seller on or prior to 10 a.m., New
      York City time, on any Business Day, then Seller shall transfer such cash
      to Buyer no later than 4 p.m. New York City time, on such Business Day. In
      the event Buyer delivers a Margin Deficit Notice to Seller after 10 a.m.,
      New York City time, on any Business Day, Seller shall be required to
      transfer such cash no later than 4 p.m., New York City time, on the
      subsequent Business Day. All cash transferred to Buyer pursuant to this
      Section 4(a) shall be deposited in the account set forth in Section 8(a)
      hereof.

(b)   Buyer's election, in its sole discretion, not to deliver a Margin Deficit
      Notice at any time there is a Margin Deficit shall not in any way limit or
      impair its right to deliver a Margin Deficit Notice at any time a Margin
      Deficit exists.

5.    INCOME PAYMENTS

(a)   Where a particular Transaction's term extends over an Income payment date
      on the Purchased Assets subject to that Transaction such Income shall be
      the property of Buyer. Buyer agrees that until a Default or an Event of
      Default has occurred and Buyer otherwise directs as contemplated in each
      Servicer Notice, each Servicer that is not Seller shall be permitted to
      continue to remit Income in accordance with the respective Servicing
      Agreement. In the event that Seller is the Servicer of any Mortgage Loans,
      Buyer agrees that until a Default or an Event of Default has occurred,
      Seller shall be permitted to continue to remit or retain Income with
      respect to such Mortgage Loans in accordance with its current existing
      business practice. Upon notice of a Default or an Event of Default to
      Seller hereunder or to Servicer pursuant to a Servicer Notice, Seller
      shall, and pursuant to the Servicer Notice, Servicer shall be required to,
      deposit promptly all Income in a deposit account (the title of which shall
      indicate that the funds therein are being held in trust for Buyer) (the
      "Collection Account") with the Bank and which is subject to the Account
      Agreement. All funds in the Collection Account may be withdrawn by Buyer
      and applied as determined by Buyer. Seller may not give any instruction
      with respect to the Collection Account after a Default or an Event of
      Default.

(b)   Notwithstanding that Buyer and Seller intend that the Transactions
      hereunder be sales to Buyer of the Purchased Assets, Seller shall pay to
      Buyer the accreted value of the Price Differential (less any amount of
      such Price Differential previously paid by Seller to Buyer) of each
      Transaction through but not including the Payment Calculation Date (each
      such payment, a "Periodic Advance Repurchase Payment") on each Payment
      Date. Buyer shall deliver to Seller, via Electronic Transmission, notice
      of the required Periodic Advance Repurchase Payment on or prior to the
      second Business Day preceding each

                                      -26-
<PAGE>

      Payment Date. If Seller fails to make all or part of the Periodic Advance
      Repurchase Payment by 5:00 p.m., New York City time, on the Payment Date,
      Seller shall be obligated to pay to Buyer (in addition to, and together
      with, the Periodic Advance Repurchase Payment) interest on the unpaid
      amount of the Periodic Advance Repurchase Payment at a rate per annum
      equal to the Post-Default Rate (the "Late Payment Fee") until the overdue
      Periodic Advance Repurchase Payment is received in full by Buyer.

(c)   Seller shall hold or cause to be held for the benefit of, and in trust
      for, Buyer all Income received by or on behalf of Seller with respect to
      such Purchased Assets. All such Income shall be held in trust for Buyer,
      shall constitute the property of Buyer and shall not be commingled with
      other property of Seller, any affiliate of Seller or the applicable
      Servicer except as expressly permitted above in this Section 5. Funds
      deposited in the Collection Account during any month shall be held
      therein, in trust for Buyer.

(d)   Buyer shall offset against the Repurchase Price of each such Transaction
      all Income and Periodic Advance Repurchase Payments actually received by
      Buyer for such Transaction pursuant to Sections 5(a), 5(b) or 11(r) as of
      the applicable Repurchase Date, respectively, excluding any Late Payment
      Fees paid pursuant to Section 5(b); it being understood that the Late
      Payment Fees are properties of Buyer that are not subject to offset
      against the Repurchase Price.

6.    REQUIREMENTS OF LAW

(a)   If any Requirement of Law (other than with respect to any amendment made
      to Buyer's certificate of incorporation and by-laws or other
      organizational or governing documents) or any change in the interpretation
      or application thereof or compliance by Buyer with any request or
      directive (whether or not having the force of law) from any central bank
      or other Governmental Authority made subsequent to the date hereof:

            (1)   shall subject Buyer to any tax of any kind whatsoever with
                  respect to this Agreement or any Transaction (excluding net
                  income taxes) or change the basis of taxation of payments to
                  Buyer in respect thereof;

            (2)   shall impose, modify or hold applicable any reserve, special
                  deposit, compulsory loan or similar requirement against assets
                  held by, deposits or other liabilities in or for the account
                  of, advances, or other extensions of credit by, or any other
                  acquisition of funds by, any office of Buyer which is not
                  otherwise included in the determination of the Eurodollar Rate
                  hereunder;

            (3)   shall impose on Buyer any other condition;

         and the result of any of the foregoing is to increase the cost to
         Buyer, by an amount which Buyer deems to be material, of entering,
         continuing or maintaining any Transaction or to reduce any amount due
         or owing hereunder in respect thereof, then, in any such case, Seller
         shall promptly pay Buyer such additional

                                      -27-
<PAGE>

         amount or amounts as calculated by Buyer in good faith as will
         compensate Buyer for such increased cost or reduced amount receivable.

(b)   If Buyer shall have determined that the adoption of or any change in any
      Requirement of Law (other than with respect to any amendment made to
      Buyer's certificate of incorporation and by-laws or other organizational
      or governing documents) regarding capital adequacy or in the
      interpretation or application thereof or compliance by Buyer or any
      corporation controlling Buyer with any request or directive regarding
      capital adequacy (whether or not having the force of law) from any
      Governmental Authority made subsequent to the date hereof shall have the
      effect of reducing the rate of return on Buyer's or such corporation's
      capital as a consequence of its obligations hereunder to a level below
      that which Buyer or such corporation could have achieved but for such
      adoption, change or compliance (taking into consideration Buyer's or such
      corporation's policies with respect to capital adequacy) by an amount
      deemed by Buyer to be material, then from time to time, Seller shall
      promptly pay to Buyer such additional amount or amounts as will compensate
      Buyer for such reduction.

(c)   Any payments made by Seller to Buyer shall be free and clear of, and
      without deduction or withholding for, any taxes; provided, however, that
      if Seller shall be required by law to deduct or withhold any taxes from
      any sums payable to Buyer, then Seller shall (A) make such deductions or
      withholdings and pay such amounts to the relevant authority in accordance
      with applicable law, (B) pay to Buyer the sum that would have been payable
      had such deduction or withholding not been made, and (C) at the time the
      Price Differential is paid, pay to Buyer all additional amounts as
      specified by Buyer to preserve the after-tax yield Buyer would have been
      received had such tax not been imposed.

(d)   If Buyer becomes entitled to claim any additional amounts pursuant to this
      Section, it shall promptly notify Seller of the event by reason of which
      it has become so entitled. A certificate as to any additional amounts
      payable pursuant to this Section 6(d) submitted by Buyer to Seller shall
      be conclusive in the absence of manifest error.

7.    SECURITY INTEREST

(a)   Each of the following items or types of property, whether now owned or
      hereafter acquired, now existing or hereafter created and wherever
      located, is hereinafter referred to as the "Purchased Items": all Mortgage
      Loans, all rights under each Purchase Agreement (but not the obligations
      thereunder), all Interest Rate Protection Agreements, all Mortgage Files,
      including without limitation all promissory notes, all Servicing Records
      relating to the Mortgage Loans, all Servicing Agreements relating to the
      Mortgage Loans and any other collateral pledged hereunder or otherwise
      relating to such Mortgage Loans, together with all files, documents,
      instruments, surveys, certificates, correspondence, appraisals, computer
      programs, computer storage media, accounting records and other books and
      records relating thereto, all mortgage guaranties and insurance (issued by
      governmental agencies or otherwise) and any mortgage insurance certificate
      or other document evidencing such mortgage guaranties or insurance
      relating to any Mortgage Loan, all servicing fees to which such Seller is
      entitled and servicing and other rights relating to the Mortgage Loans,
      all Servicer Accounts established

                                      -28-
<PAGE>

      pursuant to any Servicing Agreement and all amounts on deposit therein,
      from time to time, other agreements or contracts relating to,
      constituting, or otherwise governing, any or all of the foregoing, in each
      case, only to the extent they relate to the Purchased Assets including the
      right to receive principal and interest payments with respect to the
      Purchased Assets and the right to enforce such payments, the Collection
      Account and all monies from time to time on deposit in the Collection
      Account, all "general intangibles", "accounts", "chattel paper", "deposit
      accounts" and "investment property" as defined in the Uniform Commercial
      Code as in effect from time to time relating to or constituting any and
      all of the foregoing, and any and all replacements, substitutions,
      distributions on or proceeds of any and all of the foregoing.

(b)   Buyer and Seller intend that the Transactions hereunder be sales to Buyer
      of the Purchased Assets and not loans from Buyer to Seller secured by the
      Purchased Assets. However, in order to preserve Buyer's rights under this
      Agreement in the event that a court or other forum recharacterizes the
      Transactions hereunder as loans and as security for the performance by
      Seller of all of Seller's obligations to Buyer hereunder and the
      Transactions entered into hereunder ("Repurchase Obligations") and the
      Seller-Related Obligations, Seller hereby assigns, pledges and grants a
      security interest in all of its right, title and interest in, to and under
      the Purchased Items and the Purchased Assets to Buyer to secure the
      Repurchase Obligations and the Seller-Related Obligations, including
      without limitation the repayment of all amounts owing to Buyer hereunder.
      The assignment, pledge and grant of security interest contained herein
      shall be, and Seller hereby represents and warrants to Buyer that it is, a
      first priority perfected security interest. Seller agrees to mark its
      computer records and tapes to evidence the interests granted to Buyer
      hereunder. All Purchased Items shall secure the payment of all obligations
      of Seller now or hereafter existing under this Agreement, including,
      without limitation, Seller's obligation to repurchase Purchased Assets, or
      if such obligation is so recharacterized as a loan, to repay such loan,
      for the Repurchase Price and to pay any and all other amounts owing to
      Buyer hereunder.

(c)   Pursuant to the Custodial and Disbursement Agreement, Custodian shall hold
      the Mortgage Files as exclusive bailee and agent for Buyer pursuant to the
      terms of the Custodial and Disbursement Agreement and shall deliver to
      Buyer Trust Receipts each to the effect that Custodian has reviewed such
      Mortgage Files in the manner and to the extent required by the Custodial
      and Disbursement Agreement and identifying any deficiencies in such
      Mortgage Files as so reviewed.

8.    PAYMENT, TRANSFER AND CUSTODY

(a)   Unless otherwise mutually agreed in writing, all transfers of funds to be
      made by Seller hereunder shall be made in Dollars, in immediately
      available funds, without deduction, set-off or counterclaim, to Buyer at
      the following account maintained by Buyer; Account No. GLA 111569, account
      name SER, Bank of New York, ABA No. 021000018, Attn: Eric Seyffer, not
      later than 3 p.m., New York City time, on the date on which such payment
      shall become due (and each such payment made after such time shall be
      deemed to have been made on the next succeeding Business Day). Seller
      acknowledges that it has no rights of withdrawal from the foregoing
      account.

                                      -29-
<PAGE>

(b)   On the Purchase Date for each Transaction, ownership of the Purchased
      Assets shall be transferred to Buyer or its designee (including Custodian)
      against the simultaneous transfer of the Purchase Price as set forth in
      Section 11 of the Custodial and Disbursement Agreement not later than 6
      p.m., New York City time, simultaneously with the delivery to Custodian of
      the Purchased Assets relating to each Transaction. Seller hereby sells,
      transfers, conveys and assigns to Buyer or its designee (including
      Custodian) without recourse, but subject to the terms of this Agreement,
      all the right, title and interest of Seller in and to the Purchased Assets
      together with all right, title and interest in and to the proceeds of any
      related Purchased Items.

(c)   In connection with such sale, transfer, conveyance and assignment, on or
      prior to each Purchase Date, Seller shall deliver or cause to be delivered
      and released to Buyer or its designee (including Custodian) (i) the
      Custodial Identification Certificate and (ii) the documents identified in
      the Custodial and Disbursement Agreement.

(d)   Any Mortgage Files not delivered to Buyer or its designee (including
      Custodian) are and shall be held in trust by Seller or its designee for
      the benefit of Buyer as the owner thereof. Seller or its designee shall
      maintain a copy of the Mortgage File and the originals of the Mortgage
      File not delivered to Buyer or its designee (including Custodian). The
      possession of the Mortgage File by Seller or its designee is at the will
      of Buyer for the sole purpose of servicing the related Purchased Asset,
      and such retention and possession by Seller or its designee is in a
      custodial capacity only. Each Mortgage File retained or held by Seller or
      its designee shall be segregated on Seller's books and records from the
      other assets of Seller or its designee and the books and records of Seller
      or its designee shall be marked appropriately to reflect clearly the sale
      of the related Purchased Asset to Buyer. Seller or its designee shall
      release its custody of the Mortgage File only in accordance with written
      instructions from Buyer, unless such release is required as incidental to
      the servicing of the Purchased Assets or is in connection with a
      repurchase of any Purchased Asset by Seller.

9.    HYPOTHECATION OR PLEDGE OF PURCHASED ASSETS

Title to all Purchased Assets and Purchased Items shall pass to Buyer and Buyer
shall have free and unrestricted use of all Purchased Assets and Purchased
Items. Nothing in this Agreement shall preclude Buyer from engaging in
repurchase transactions with the Purchased Assets and Purchased Items or
otherwise pledging, repledging, transferring, hypothecating, or rehypothecating
the Purchased Assets and Purchased Items, all on terms that Buyer may determine
in its sole discretion; provided, that Buyer shall remain obligated to resell
the Purchased Assets to Seller as provided herein. Nothing contained in this
Agreement shall obligate Buyer to segregate any Purchased Assets and Purchased
Items delivered to Buyer by Seller.

10.   SELLER REPRESENTATIONS

Seller represents and warrants to Buyer that as of the Purchase Date for the
purchase of any Purchased Assets by Buyer from Seller and as of the date of this
Agreement and any Transaction

                                      -30-
<PAGE>

hereunder and at all times while the Repurchase Documents and any Transaction
hereunder is in full force and effect:

(a)   Acting as Principal. Seller will engage in such Transactions as principal
      (or, if agreed in writing in advance of any Transaction by the other party
      hereto, as agent for a disclosed principal);

(b)   Solvency. Neither the Repurchase Documents nor any Transaction thereunder
      are entered into in contemplation of insolvency or with intent to hinder,
      delay or defraud any of Seller's creditors. The transfer of the Mortgage
      Loans subject hereto and the obligation to repurchase such Mortgage Loans
      is not undertaken with the intent to hinder, delay or defraud any of
      Seller's creditors. Seller is not insolvent within the meaning of 11
      U.S.C. Section 101(32) or any successor provision thereof and the transfer
      and sale of the Mortgage Loans pursuant hereto and the obligation to
      repurchase such Mortgage Loan (i) will not cause Seller to become
      insolvent, (ii) will not result in Seller having unreasonably small
      capital, and (iii) will not result in debts that would be beyond Seller's
      ability to pay as the same mature. Seller received reasonably equivalent
      value in exchange for the transfer and sale of the Purchased Assets and
      Purchased Items subject hereto;

(c)   No Broker. Seller has not dealt with any broker, investment banker, agent,
      or other person, except for Buyer, who may be entitled to any commission
      or compensation in connection with the sale of Purchased Assets pursuant
      to this Agreement;

(d)   Ability to Perform. Seller does not believe, nor does it have any reason
      or cause to believe, that either it or FBR cannot perform each and every
      covenant contained in the Repurchase Documents applicable to such Person;

(e)   No Defaults. No Default or Event of Default has occurred and is continuing
      hereunder;

(f)   Legal Name; Existence; Organizational Identification Number. Seller's
      exact legal name is, and for the immediately preceding four months has
      been, Oak Street Mortgage LLC. Seller (a) is, and for the immediately
      preceding twelve months has been, a limited liability company duly and
      exclusively organized, validly existing and in good standing under the
      laws of Delaware; (b) has all requisite corporate or other power, and has
      all governmental licenses, authorizations, consents and approvals
      necessary to own its assets and carry on its business as now being or as
      proposed to be conducted, except where the lack of such licenses,
      authorizations, consents and approvals would not be reasonably likely to
      have a Material Adverse Effect; and (c) is qualified to do business and is
      in good standing in all other jurisdictions in which the nature of the
      business conducted by it makes such qualification necessary, except where
      failure so to qualify could not be reasonably likely (either individually
      or in the aggregate) to have a Material Adverse Effect. Seller's
      organizational identification number assigned by the state of Delaware is
      3104536.

(g)   Financial Condition. Seller has heretofore furnished to Buyer a copy of
      (a) its consolidated balance sheet and the consolidating balance sheets of
      its consolidated

                                      -31-
<PAGE>

      Subsidiaries for the fiscal year ended December 31, 2003, and the related
      consolidated statements of income and retained earnings and of cash flows
      for Seller and its consolidated Subsidiaries for such fiscal year, each
      audited by and with the unqualified opinion thereon of Deloitte & Touche
      LLP and (b) its consolidated balance sheet and the consolidating balance
      sheets of its consolidated Subsidiaries for the quarterly fiscal period of
      Seller ended March 31, 2004 and the related consolidated statements of
      income and retained earnings and of cash flows for Seller and its
      consolidated Subsidiaries for such quarterly fiscal period, setting forth
      in each case in comparative form the figures for the previous year. All
      such financial statements are complete and correct and fairly present, in
      all material respects, the consolidated financial position of Seller and
      its Subsidiaries and the consolidated results of their operations as at
      such dates and for such fiscal periods, all in accordance with GAAP
      applied on a consistent basis. Since March 31, 2004, there has been no
      material adverse change in the consolidated business, operations or
      financial condition of Seller and its consolidated Subsidiaries taken as a
      whole from that set forth in said financial statements.

(h)   Litigation. There are no actions, suits, arbitrations, investigations
      (including, without limitation, any of the foregoing which are pending or
      threatened) or other legal or arbitrable proceedings affecting Seller or
      any of its Subsidiaries or affecting any of the Property of any of them
      before any Governmental Authority which (i) questions or challenges the
      validity or enforceability of the Repurchase Documents or any action to be
      taken in connection with the transactions contemplated hereby, (ii) other
      than with respect FBR, makes a claim or claims in an aggregate amount
      greater than $1,000,000, or (iii) individually or in the aggregate, if
      adversely determined, could reasonably be likely to have a Material
      Adverse Effect.

(i)   No Breach. Neither (a) the execution and delivery of the Repurchase
      Documents nor (b) the consummation of the transactions therein
      contemplated to be entered into by Seller in compliance with the terms and
      provisions thereof will conflict with or result in a breach of the
      organizational documents of Seller or any applicable law, rule or
      regulation, or any order, writ, injunction or decree of any Governmental
      Authority, or any Servicing Agreement or other material agreement or
      instrument to which Seller or any of its Subsidiaries is a party or by
      which any of them or any of their Property is bound or to which any of
      them is subject, or constitute a default under any such material agreement
      or instrument or result in the creation or imposition of any Lien (except
      for the Liens created pursuant to the Repurchase Documents) upon any
      Property of Seller or any of its Subsidiaries pursuant to the terms of any
      such agreement or instrument.

(j)   Action. Seller has all necessary corporate or other power, authority and
      legal right to execute, deliver and perform its obligations under each of
      the Repurchase Documents to which it is a party, as applicable; the
      execution, delivery and performance by Seller of each of the Repurchase
      Documents to which it is a party have been duly authorized by all
      necessary corporate or other action on its part; and each Repurchase
      Document to which it is a party has been duly and validly executed and
      delivered by Seller and constitutes a legal, valid and binding obligation
      of Seller enforceable against Seller in accordance with its terms.

                                      -32-
<PAGE>

(k)   Approvals. No authorizations, approvals or consents of, and no filings or
      registrations with, any Governmental Authority or any securities exchange
      are necessary for the execution, delivery or performance by Seller of the
      Repurchase Documents or for the legality, validity or enforceability
      thereof, except for filings and recordings in respect of the Liens created
      pursuant to the Repurchase Documents.

(l)   Margin Regulations. Neither any Transaction hereunder, nor the use of the
      proceeds thereof, will violate or be inconsistent with the provisions of
      Regulation T, U or X. In addition, Seller agrees that it will not use any
      proceeds obtained from or through Transactions for the purpose of buying,
      carrying or trading in securities or buying or carrying any part of an
      investment contract security within the meaning of Section 220.2 of
      Regulation T promulgated by the Board of Governors of the Federal Reserve
      System pursuant to Section 7 of the Securities Exchange Act of 1934.

(m)   Taxes. Seller and its respective Subsidiaries have filed all federal
      income tax returns and all other material tax returns that are required to
      be filed by them and have paid all taxes due pursuant to such returns or
      pursuant to any assessment received by it or any of its Subsidiaries,
      except for any such taxes as are being appropriately contested in good
      faith by appropriate proceedings diligently conducted and with respect to
      which adequate reserves have been provided. The charges, accruals and
      reserves on the books of Seller and its respective Subsidiaries in respect
      of taxes and other governmental charges are, in the opinion of Seller,
      adequate.

(n)   Investment Company Act. Neither Seller nor any of its Subsidiaries is an
      "investment company", or a company "controlled" by an "investment
      company," within the meaning of the Investment Company Act of 1940, as
      amended.

(o)   Purchased Assets.

      (1)   Seller has not assigned, pledged, or otherwise conveyed or
            encumbered any Mortgage Loan to any other Person, and immediately
            prior to the sale of such Mortgage Loan to Buyer, Seller was the
            sole legal and beneficial owner of such Mortgage Loan and had good
            and marketable title thereto, free and clear of all Liens, in each
            case except for Liens to be released simultaneously with the sale to
            Buyer hereunder. No Mortgage Loan sold to Buyer hereunder was
            acquired (by purchase or otherwise) by Seller from an Affiliate of
            Seller unless a True Sale Certification has been delivered to Buyer
            and unless such transaction (1) is not otherwise expressly
            prohibited under this Agreement, (2) was upon fair and reasonable
            terms no less favorable to Seller than it would obtain in a
            comparable arm's length transaction with a Person which is not an
            Affiliate and (3) was a sale that would not be recharacterized as a
            financing in the event of a bankruptcy, insolvency or other similar
            proceeding.

      (2)   The provisions of this Agreement are effective to either constitute
            a sale of Purchased Items to Buyer or to create in favor of Buyer a
            valid and fully perfected first priority security interest in all
            right, title and interest of Seller in, to and under the Purchased
            Items.

                                      -33-
<PAGE>

      (3)   Upon receipt by Custodian of each Mortgage Note, endorsed in blank
            by a duly authorized officer of Seller, either a purchase shall have
            been completed by Buyer of each Mortgage Note or Buyer shall have a
            valid and fully perfected first priority security interest in the
            applicable Mortgage Note and in such Seller's interest in the
            related Mortgaged Property.

      (4)   Upon the filing of financing statements on Form UCC-1 naming Buyer
            as "Secured Party", Seller as "Debtor" and describing the Purchased
            Items, in the jurisdictions and recording offices listed on Exhibit
            IV attached hereto, the security interests granted hereunder in the
            Purchased Items will constitute valid and fully perfected security
            interests under the Uniform Commercial Code in all right, title and
            interest of Seller in, to and under such Purchased Items, which can
            be perfected by filing under the Uniform Commercial Code.

      (5)   Upon execution and delivery of the Account Agreement, Buyer shall
            either be the owner of, or have a valid and fully perfected first
            priority security interest in, the investment property and all
            deposit accounts comprising Purchased Items.

      (6)   With respect to each Purchased Asset, each of the representations
            and warranties on Schedule 1 is true and correct.

(p)   Location of Books and Records. The location where Seller keeps its books
      and records, including all computer tapes and records related to the
      Purchased Items is its chief executive office.

(q)   Hedging Policies. (1) Seller shall hedge all Purchased Assets in
      accordance with the Hedging Policies. Seller shall not make any material
      change to its Hedging Policies without the prior written consent of Buyer,
      which shall be deemed given if written notice to the contrary, including
      the reason(s) therefor, is not received by Seller within five (5) Business
      Days following Seller's written notice to Buyer, confirmed via telephone,
      of any such change, and Seller shall review the Hedging Policies
      periodically to confirm that they are being complied with in all material
      respects and are adequate to meet Seller's business objectives. (2) In the
      event Seller makes any amendment or modification to the Hedging Policies,
      Seller shall within 30 days of such amendment or modification deliver to
      Buyer a complete copy of the amended or modified Hedging Policies.
      Additionally, Buyer may in its reasonable discretion request a current
      copy of its Hedging Policies at any time.

(r)   Servicing Agreements. Seller has delivered to Buyer all Servicing
      Agreements with respect to the Purchased Assets and no default or event of
      default exists thereunder.

(s)   Existing Financing Facilities. All credit facilities, repurchase
      facilities or substantially similar facilities of Seller which are
      presently in effect are listed under the definition of "Existing Financing
      Facilities" and no defaults or events of default exist thereunder. The
      financial covenants hereunder are at least equal to those Seller makes
      under each of the Existing Financing Facilities. Seller shall give Buyer
      10 Business Days prior notification of any amendment to any financial
      covenant in any Existing Financing Facility that

                                      -34-
<PAGE>

      increases the obligations or requirements of Seller thereunder, and Buyer
      shall have the option, at Buyer's sole discretion, to amend this Agreement
      to incorporate a substantially similar financial covenant.

(t)   True and Complete Disclosure. The information, reports, financial
      statements, exhibits and schedules furnished in writing by or on behalf of
      Seller to Buyer in connection with the negotiation, preparation or
      delivery of this Agreement and the other Repurchase Documents or included
      herein or therein or delivered pursuant hereto or thereto (other than with
      respect to the Mortgage Loans), when taken as a whole, do not contain any
      untrue statement of material fact or omit to state any material fact
      necessary to make the statements herein or therein, in light of the
      circumstances under which they were made, not misleading. All written
      information furnished after the date hereof by or on behalf of Seller to
      Buyer in connection with this Agreement and the other Repurchase Documents
      and the transactions contemplated hereby (other than with respect to the
      Mortgage Loans) and thereby will be true, complete and accurate in every
      material respect, or (in the case of projections) based on reasonable
      estimates, on the date as of which such information is stated or
      certified. There is no fact known to a Responsible Officer of Seller,
      after due inquiry, that could reasonably be expected to have a Material
      Adverse Effect that has not been disclosed herein, in the other Repurchase
      Documents or in a report, financial statement, exhibit, schedule,
      disclosure letter or other writing furnished to Buyer for use in
      connection with the transactions contemplated hereby or thereby.

(u)   ERISA. Each Plan to which Seller or any of its Subsidiaries make direct
      contributions, and, to the knowledge of Seller, each other Plan and each
      Multiemployer Plan, is in compliance in all material respects with, and
      has been administered in all material respects in compliance with, the
      applicable provisions of ERISA, the Code and any other Federal or State
      law. No event or condition has occurred and is continuing as to which
      Seller would be under an obligation to furnish a report to Buyer under
      Section 11(a)(4).

(v)   No Reliance. Seller has made its own independent decisions to enter into
      the Repurchase Documents and each Transaction and as to whether such
      Transaction is appropriate and proper for it based upon its own judgment
      and upon advice from such advisors (including without limitation, legal
      counsel and accountants) as it has deemed necessary. Seller is not relying
      upon any advice from Buyer as to any aspect of the Transactions, including
      without limitation, the legal, accounting or tax treatment of such
      Transactions.

(w)   Compliance with Anti-Money Laundering Laws. Seller has complied with all
      applicable anti-money laundering laws and regulations, including without
      limitation the USA Patriot Act of 2001 (collectively, the "Anti-Money
      Laundering Laws"); Seller has established an adequate anti-money
      laundering compliance program as required by the Anti-Money Laundering
      Laws, has conducted the requisite due diligence in connection with the
      origination of each Mortgage Loan for purposes of the Anti-Money
      Laundering Laws, including with respect to the legitimacy of the
      applicable Mortgagor and the origin of the assets used by the said
      Mortgagor to purchase the property in question, and maintains, and will
      maintain, sufficient information to identify the applicable Mortgagor for
      purposes of the Anti-Money Laundering Laws.

                                      -35-

(x)   Other Security Agreements. Seller has not become bound under Section
      9-203(d) of the UCC by a Security Agreement previously entered into by
      another Person.

11.   COVENANTS OF SELLER

      On and as of the date of this Agreement and each Purchase Date and until
      this Agreement is no longer in force with respect to any Transaction,
      Seller covenants that:

(a)   Financial Statements. Seller shall deliver to Buyer:

      (1)   as soon as available and in any event within thirty (30) calendar
            days after the end of each calendar month, the unaudited
            consolidated balance sheets of Seller and its consolidated
            Subsidiaries as at the end of such period and the related unaudited
            consolidated statements of income and retained earnings and of cash
            flows for Seller and its consolidated Subsidiaries for such period
            and the portion of the fiscal year through the end of such period,
            accompanied by a certificate of a Responsible Officer of Seller,
            which certificate shall state that said consolidated financial
            statements fairly present in all material respects the consolidated
            financial condition and results of operations of Seller and its
            consolidated Subsidiaries in accordance with GAAP, consistently
            applied, as at the end of, and for, such period (subject to normal
            year-end adjustments);

      (2)   as soon as available and in any event within ninety (90) days after
            the end of each fiscal year of Seller, the consolidated balance
            sheets of Seller and its consolidated Subsidiaries as at the end of
            such fiscal year and the related consolidated statements of income
            and retained earnings and of cash flows for Seller and its
            consolidated Subsidiaries for such year, setting forth in each case
            in comparative form the figures for the previous year, accompanied
            by an opinion thereon of independent certified public accountants of
            recognized national standing, which opinion shall not be qualified
            as to scope of audit or going concern and shall state that said
            consolidated financial statements fairly present the consolidated
            financial condition and results of operations of Seller and its
            respective consolidated Subsidiaries as at the end of, and for, such
            fiscal year in accordance with GAAP, and a certificate of such
            accountants stating that, in making the examination necessary for
            their opinion, they obtained no knowledge, except as specifically
            stated, of any Default or Event of Default;

      (3)   from time to time such other information regarding the financial
            condition, operations, or business of Seller as Buyer may reasonably
            request; and

      (4)   as soon as reasonably possible, and in any event within thirty (30)
            days after a Responsible Officer of Seller knows, or with respect to
            any Plan or Multiemployer Plan to which Seller or any of its
            Subsidiaries makes direct contributions, has reason to believe, that
            any of the events or conditions specified below with respect to any
            Plan or Multiemployer Plan has occurred or exists, a statement
            signed by a senior financial officer of Seller setting forth details
            respecting such event or condition and the action, if any, that
            Seller or its ERISA

                                      -36-

            Affiliate proposes to take with respect thereto (and a copy of any
            report or notice required to be filed with or given to PBGC by
            Seller or an ERISA Affiliate with respect to such event or
            condition):

                        (A) any reportable event, as defined in Section 4043(c)
                  of ERISA or any successor provision thereof and the
                  regulations issued thereunder, with respect to a Plan, as to
                  which PBGC has not by regulation waived the requirement of
                  Section 4043(a) of ERISA that it be notified within thirty
                  (30) days of the occurrence of such event (provided that a
                  failure to meet the minimum funding standard of Section 412 of
                  the Code or Section 302 of ERISA or any successor provision
                  thereof, including without limitation the failure to make on
                  or before its due date a required installment under Section
                  412(m) of the Code or Section 302(e) of ERISA or any successor
                  provision thereof, shall be a reportable event regardless of
                  the issuance of any waivers in accordance with Section 412(d)
                  of the Code or any successor provision thereof); and any
                  request for a waiver under Section 412(d) of the Code or any
                  successor provision thereof for any Plan;

                        (B) the distribution under Section 4041(c) of ERISA or
                  any successor provision thereof of a notice of intent to
                  terminate any Plan or any action taken by Seller or an ERISA
                  Affiliate to terminate any Plan;

                        (C) the institution by PBGC of proceedings under Section
                  4042 of ERISA or any successor provision thereof for the
                  termination of, or the appointment of a trustee to administer,
                  any Plan, or the receipt by Seller or any ERISA Affiliate of a
                  notice from a Multiemployer Plan that such action has been
                  taken by PBGC with respect to such Multiemployer Plan;

                        (D) the complete or partial withdrawal from a
                  Multiemployer Plan by Seller or any ERISA Affiliate that
                  results in liability under Section 4201 or 4204 of ERISA or
                  any successor provision thereof (including the obligation to
                  satisfy secondary liability as a result of a purchaser
                  default) that would have a Material Adverse Effect or the
                  receipt by Seller or any ERISA Affiliate of notice from a
                  Multiemployer Plan that it is in reorganization or insolvency
                  pursuant to Section 4241 or 4245 of ERISA or any successor
                  provision thereof or that it intends to terminate or has
                  terminated under Section 4041A of ERISA or any successor
                  provision thereof;

                        (E) the institution of a proceeding by a fiduciary of
                  any Multiemployer Plan against Seller or any ERISA Affiliate
                  to enforce Section 515 of ERISA or any successor provision
                  thereof, which proceeding is not dismissed within thirty (30)
                  days; and

                        (F) the adoption of an amendment to any Plan that would
                  result in the loss of tax-exempt status of the trust of which
                  such Plan is a part if

                                      -37-
<PAGE>

                  Seller or an ERISA Affiliate fails to provide timely security
                  to such Plan in accordance with the provisions of Section
                  401(a)(29) of the Code or Section 307 of ERISA or any
                  successor provision thereof.

      Seller will furnish to Buyer, at the time Seller furnishes each set of
      financial statements pursuant to paragraphs (a)(1) and (a)(2) above, a
      certificate of a Responsible Officer of Seller to the effect that, to the
      best of such Responsible Officer's knowledge, Seller during such fiscal
      period or year has observed or performed in all material respects all of
      its covenants and other agreements, and satisfied every condition,
      contained in this Agreement and the other Repurchase Documents to be
      observed, performed or satisfied by it, and that such Responsible Officer

                  Income paid after such exercise or deemed exercise shall be
                  retained by Buyer and applied to the aggregate unpaid
                  Repurchase Prices and any other amounts owed by Seller
                  hereunder, and (iii) Seller shall immediately deliver to Buyer
                  any Purchased Assets subject to such Transactions then in
                  Seller's possession or control;

                        (B) to the extent permitted by applicable law, the
                  Repurchase Price with respect to each such Transaction shall
                  be increased by the aggregate amount obtained by daily
                  application of, on a 360-day per year basis for the actual
                  number of days during the period from and including the date
                  of the exercise or deemed exercise of such option to but
                  excluding the date of payment of the Repurchase Price, (x) the
                  Post-Default Rate to (y) the Repurchase Price for such
                  Transaction as of the Repurchase Date (decreased as of any day
                  by (i) any amounts actually in the possession of Buyer
                  pursuant to clause (C) of this subsection, (ii) any proceeds
                  from the sale of Purchased Assets applied to the Repurchase
                  Price pursuant to subsection (a)(4) of this Section 13, and
                  (iii) any amounts applied to the Repurchase Price pursuant to
                  subsection (a)(4) of this Section 13); and

                        (C) all Income actually received by Buyer pursuant to
                  Section 5 (excluding any Late Payment Fees paid pursuant to
                  Section 5(b)) shall be applied to the aggregate unpaid
                  Repurchase Price owed by Seller.

      (3)   Upon the occurrence of one or more Events of Default, Buyer shall
            have the right to obtain physical possession of the Servicing
            Records (subject to the provisions of the Custodial and Disbursement
            Agreement) and all other files of Seller relating to the Purchased
            Assets and all documents relating to the Purchased Assets which are
            then or may thereafter come in to the possession of Seller or any
            third party acting for Seller and Seller shall deliver to Buyer such
            assignments as Buyer shall request and Buyer shall have the right to
            appoint any Person to act as Servicer for the Purchased Assets.
            Buyer shall be entitled to specific performance of all agreements of
            Seller contained in the Repurchase Documents.

      (4)   At any time on the Business Day following notice to Seller (which
            notice may be the notice given under subsection (a)(1) of this
            Section 13), in the event Seller has not repurchased all Purchased
            Assets, Buyer may (A) immediately sell, without demand or further
            notice of any kind, at a public or private sale and at such price or
            prices as Buyer may deem satisfactory any or all Purchased Assets
            subject to such Transactions hereunder and apply the proceeds
            thereof to the aggregate unpaid Repurchase Price and any other
            amounts owing by Seller hereunder or (B) in its sole discretion
            elect, in lieu of selling all or a portion of such Purchased Assets,
            to give Seller credit for such Purchased Assets in an amount equal
            to the Market Value of the Purchased Assets against the aggregate
            unpaid Repurchase Price and any other amounts owing by Seller
            hereunder. The proceeds of any disposition of Purchased Assets shall
            be applied first to the costs and expenses

                                      -46-
<PAGE>

            incurred by Buyer in connection with Seller's default; second to
            costs of related covering and/or related hedging transactions; third
            to the Repurchase Price; and fourth to any other outstanding
            obligation of Seller to Buyer or its Affiliates. In connection with
            any sale pursuant to clause (A) of this subsection (a)(4), Buyer may
            (i) sell any such Purchased Assets without giving any warranties and
            (ii) specifically disclaim or modify any warranties of title or the
            like, and this procedure shall not be considered to adversely effect
            the commercial reasonableness of any such sale of Purchased Assets.

      (5)   Seller agrees that Buyer may obtain an injunction or an order of
            specific performance to compel Seller to fulfill its obligations as
            set forth in Section 24, if Seller fails or refuses to perform its
            obligations as set forth therein.

      (6)   Seller shall be liable to Buyer, payable as and when incurred by
            Buyer, for (A) the amount of all actual out-of-pocket expenses,
            including legal or other expenses incurred by Buyer in connection
            with or as a consequence of an Event of Default, and (B) all costs
            incurred in connection with hedging or covering transactions.

      (7)   Buyer shall have, in addition to its rights hereunder, any rights
            otherwise available to it under any other agreement or applicable
            law.

(b)   Buyer may exercise one or more of the remedies available to Buyer
      immediately upon the occurrence of an Event of Default and, except to the
      extent provided in subsections (a)(1) and (4) of this Section 13, at any
      time thereafter without notice to Seller. All rights and remedies arising
      under this Agreement as amended from time to time hereunder are cumulative
      and not exclusive of any other rights or remedies which Buyer may have.

(c)   Buyer may enforce its rights and remedies hereunder without prior judicial
      process or hearing, and Seller hereby expressly waives any defenses Seller
      might otherwise have to require Buyer to enforce its rights by judicial
      process. Seller also waives any defense (other than a defense of payment
      or performance) Seller might otherwise have arising from the use of
      nonjudicial process, enforcement and sale of all or any portion of the
      Purchased Items, or from any other election of remedies. Seller recognizes
      that nonjudicial remedies are consistent with the usages of the trade, are
      responsive to commercial necessity and are the result of a bargain at
      arm's-length.

(d)   To the extent permitted by applicable law, Seller shall be liable to Buyer
      for interest on any amounts owing by Seller hereunder, from the date
      Seller becomes liable for such amounts hereunder until such amounts are
      (i) paid in full by Seller or (ii) satisfied in full by the exercise of
      Buyer's rights hereunder. Interest on any sum payable by Seller to Buyer
      under this paragraph 13(d) shall be at a rate equal to the Post-Default
      Rate.

14.   INDEMNIFICATION AND EXPENSES

(a)   Seller agrees to hold Buyer and its Affiliates and their present and
      former respective officers, directors, employees, agents, advisors and
      other representatives (each, an "Indemnified Party") harmless from and
      indemnify any Indemnified Party against all liabilities, losses, damages,
      judgments, costs and expenses of any kind which may be

                                      -47-
<PAGE>

      imposed on, incurred by or asserted against such Indemnified Party
      (including counsel's fees and disbursements) (collectively, "Costs"),
      relating to or arising out of this Agreement, any other Repurchase
      Document or any transaction contemplated hereby or thereby, or any
      amendment, supplement or modification of, or any waiver or consent under
      or in respect of, this Agreement, any other Repurchase Document or any
      transaction contemplated hereby or thereby, that, in each case, results
      from anything other than the Indemnified Party's gross negligence or
      willful misconduct. Without limiting the generality of the foregoing,
      Seller agrees to hold any Indemnified Party harmless from and indemnify
      such Indemnified Party against all Costs with respect to all Mortgage
      Loans relating to or arising out of any violation or alleged violation of
      any environmental law, rule or regulation or any consumer credit laws,
      including without limitation the federal Truth in Lending Act and/or the
      federal Real Estate Settlement Procedures Act, that, in each case, results
      from anything other than the Indemnified Party's gross negligence or
      willful misconduct. In any suit, proceeding or action brought by an
      Indemnified Party in connection with any Mortgage Loan for any sum owing
      thereunder, or to enforce any provisions of any Mortgage Loan, Seller will
      save, indemnify and hold such Indemnified Party harmless from and against
      all expense, loss or damage suffered by reason of any defense, set-off,
      counterclaim, recoupment or reduction or liability whatsoever of the
      account debtor or obligor thereunder, arising out of a breach by Seller of
      any obligation thereunder or arising out of any other agreement,
      indebtedness or liability at any time owing to or in favor of such account
      debtor or obligor or its successors from Seller. Seller also agrees to
      reimburse an Indemnified Party as and when billed by such Indemnified
      Party for all the Indemnified Party's costs and expenses incurred in
      connection with the enforcement or the preservation of Buyer's rights
      under this Agreement, any other Repurchase Document or any transaction
      contemplated hereby or thereby, including without limitation the fees and
      disbursements of its counsel.

(b)   Seller agrees to pay as and when billed by Buyer all of the out-of-pocket
      costs and expenses (including legal fees and any costs associated with any
      upfront due diligence costs, including appraisals) incurred by Buyer in
      connection with the development, preparation and execution of, this
      Agreement, any other Repurchase Document or any other documents prepared
      in connection herewith (the "Initial Costs"). Seller agrees to pay as and
      when billed by Buyer, as part of the Initial Costs, all of the
      out-of-pocket costs and expenses incurred in connection with any
      amendment, supplement or modification to this Agreement or any other
      Repurchase Document or any other document prepared in connection
      therewith. Seller agrees to pay as and when billed by Buyer all of the
      out-of-pocket costs and expenses incurred in connection with the
      consummation and administration of the transactions contemplated hereby
      and thereby including without limitation all fees, disbursements and
      expenses of counsel to Buyer which amount shall be deducted from the
      Purchase Price paid for the first Transaction hereunder; provided that the
      Initial Costs shall not exceed $65,000 without the prior written consent
      of Seller, which such consent shall not be unreasonably withheld. Subject
      to the limitations set forth in Section 26, Seller agrees to pay Buyer all
      the out-of-pocket due diligence, inspection, appraisals, testing and
      review costs and expenses incurred by Buyer with respect to Mortgage Loans
      submitted by Seller for purchase under this Agreement,

                                      -48-
<PAGE>

      including, but not limited to, those out-of-pocket costs and expenses
      incurred by Buyer pursuant to Sections 24 and 26.

15.   RECORDING OF COMMUNICATIONS

      Buyer and Seller shall have the right (but not the obligation) from time
      to time to make or cause to be made tape recordings of communications
      between its employees and those of the other party with respect to
      Transactions upon notice to the other party of such recording. Buyer and
      Seller consent to the admissibility of such tape recordings in any court,
      arbitration, or other proceedings. The parties agree that a duly
      authenticated transcript of such a tape recording shall be deemed to be a
      writing conclusively evidencing the parties' agreement.

16.   SINGLE AGREEMENT

      Buyer and Seller acknowledge that, and have entered hereinto and will
      enter into each Transaction hereunder in consideration of and in reliance
      upon the fact that, all Transactions hereunder constitute a single
      business and contractual relationship and that each has been entered into
      in consideration of the other Transactions. Accordingly, each of Buyer and
      Seller agrees (i) to perform all of its obligations in respect of each
      Transaction hereunder, and that a default in the performance of any such
      obligations shall constitute a default by it in respect of all
      Transactions hereunder, (ii) that each of them shall be entitled to set
      off claims and apply property held by them in respect of any Transaction
      against obligations owing to them in respect of any other Transaction
      hereunder; (iii) that payments, deliveries, and other transfers made by
      either of them in respect of any Transaction shall be deemed to have been
      made in consideration of payments, deliveries, and other transfers in
      respect of any other Transactions hereunder, and the obligations to make
      any such payments, deliveries, and other transfers may be applied against
      each other and netted and (iv) to promptly provide notice to the other
      after any such set off or application.

17.   NOTICES AND OTHER COMMUNICATIONS

      Except as otherwise expressly permitted by this Agreement, all notices,
      requests and other communications provided for herein and under the
      Custodial and Disbursement Agreement (including without limitation any
      modifications of, or waivers, requests or consents under, this Agreement)
      shall be given or made in writing (including without limitation by email,
      telex or telecopy) delivered to the intended recipient at the "Address for
      Notices" specified below its name on the signature pages hereof or
      thereof); or, as to any party, at such other address as shall be
      designated by such party in a written notice to each other party. Except
      as otherwise provided in this Agreement and except for notices given under
      Section 3 (which shall be effective only on receipt), all such
      communications shall be deemed to have been duly given when transmitted by
      telecopy or personally delivered or, in the case of a mailed notice, upon
      receipt.

18.   ENTIRE AGREEMENT; SEVERABILITY; MODIFICATIONS

      This Agreement together with the other Repurchase Documents and the
      Account Agreement constitute the entire understanding between Buyer and
      Seller with respect to the subject matter it covers and shall supersede
      any existing agreements between the parties containing general terms and
      conditions for repurchase transactions involving Purchased Assets. By
      acceptance of this Agreement, Buyer and Seller acknowledge that they have
      not made, and are not relying upon, any statements, representations,
      promises or undertakings not contained in this Agreement. Each provision
      and agreement herein shall be treated as separate and independent from any
      other provision or agreement herein and shall be enforceable
      notwithstanding the unenforceability of any such other provision or
      agreement. No amendment, modification or release from any provision of
      this Agreement shall be effective unless in writing and executed by or on
      behalf of the party or parties to be charged therewith and shall be
      effective only in the specific instance and for the specific purpose for
      which given.

19.   NON-ASSIGNABILITY

      The rights and obligations of the parties under this Agreement and under
      any Transaction shall not be assigned by Seller without the prior written
      consent of Buyer, and any attempted assignment without such consent shall
      be null and void. It is understood and agreed the Buyer at any time may
      assign this Agreement and each other Repurchase Document to FBR in its
      sole discretion. Subject to the foregoing, this Agreement and any
      Transactions shall be binding upon and shall inure to the benefit of the
      parties and their respective successors and assigns. Nothing in this
      Agreement express or implied, shall give to any person, other than the
      parties to this Agreement and their successors hereunder, any benefit of
      any legal or equitable right, power, remedy or claim under this Agreement.

20.   TERMINABILITY

      Except as set forth below, this Agreement may not be terminated. This
      Agreement may be terminated by Seller upon 30 days' written notice to
      Buyer; provided Seller shall pay to Buyer the Termination Fee, except that
      this Agreement shall, notwithstanding such notice, remain applicable to
      any Transaction then outstanding. Each representation and warranty made or
      deemed to be made by entering into a Transaction, herein or pursuant
      hereto shall survive the making of such representation and warranty, and
      Buyer shall not be deemed to have waived any Default that may arise
      because any such representation or warranty shall have proved to be false
      or misleading, notwithstanding that Buyer may have had notice or knowledge
      or reason to believe that such representation or warranty was false or
      misleading at the time the Transaction was made. Notwithstanding any such
      termination or the occurrence of an Event of Default, all of the
      representations and warranties and covenants hereunder shall continue and
      survive. The obligations of Seller under Section 14 shall survive the
      termination of this Agreement.

      OF THE STATE OF NEW YORK WITHOUT REGARD TO THE CONFLICTS OF LAW
      PRINCIPLES.

22.   SUBMISSION TO JURISDICTION; WAIVERS

      EACH OF BUYER AND SELLER HEREBY IRREVOCABLY AND UNCONDITIONALLY:

      (A)   SUBMITS FOR ITSELF AND ITS PROPERTY IN ANY LEGAL ACTION OR
            PROCEEDING RELATING TO THIS AGREEMENT AND THE OTHER REPURCHASE
            DOCUMENTS, OR FOR RECOGNITION AND ENFORCEMENT OF ANY JUDGMENT IN

            THE FEDERAL COURTS OF THE UNITED STATES OF AMERICA FOR THE SOUTHERN
            DISTRICT OF NEW YORK, AND APPELLATE COURTS FROM ANY THEREOF;

      (B)   CONSENTS THAT ANY SUCH ACTION OR PROCEEDING MAY BE BROUGHT IN SUCH
            COURTS AND, TO THE EXTENT PERMITTED BY LAW, WAIVES ANY OBJECTION
            THAT IT MAY NOW OR HEREAFTER HAVE TO THE VENUE OF ANY SUCH ACTION OR
            PROCEEDING IN ANY SUCH COURT OR THAT SUCH ACTION OR PROCEEDING WAS
            BROUGHT IN AN INCONVENIENT COURT AND AGREES NOT TO PLEAD OR CLAIM
            THE SAME;

      (C)   AGREES THAT SERVICE OF PROCESS IN ANY SUCH ACTION OR PROCEEDING MAY

            TRANSACTIONS CONTEMPLATED HEREBY OR THEREBY.

23.   NO WAIVERS, ETC.

      No failure on the part of Buyer to exercise and no delay in exercising,
      and no course of dealing with respect to, any right, power or privilege
      under any Repurchase Document shall operate as a waiver thereof, nor shall
      any single or partial exercise of any right, power or privilege under any
      Repurchase Document preclude any other or further exercise thereof or the
      exercise of any other right, power or privilege. The remedies provided
      herein are cumulative and not exclusive of any remedies provided by law.
      An Event of Default shall be deemed to be continuing unless expressly
      waived by Buyer in writing.

24.   SERVICING

(a)   Seller covenants to maintain or cause the servicing of the Mortgage Loans
      to be maintained in conformity with accepted and prudent servicing
      practices in the industry for the same type of mortgage loans as the
      Mortgage Loans and in a manner at least equal in quality to the servicing
      Seller provides for mortgage loans which it owns. In the event that the
      preceding language is interpreted as constituting one or more servicing
      contracts, each such servicing contract shall terminate automatically upon
      the earliest of (i) an Event of Default, (ii) the date on which this
      Agreement terminates or (iii) the transfer of servicing approved by Buyer.

(b)   If the Mortgage Loans are serviced by Seller, Seller agrees that Buyer is
      the owner of all servicing records, including but not limited to any and
      all servicing agreements, files, documents, records, data bases, computer
      tapes, copies of computer tapes, proof of insurance coverage, insurance
      policies, appraisals, other closing documentation, payment history
      records, and any other records relating to or evidencing the servicing of
      the Mortgage Loans (the "Servicing Records"). Seller covenants to
      safeguard such Servicing Records and to deliver them promptly to Buyer or
      its designee (including Custodian) at Buyer's request.

(c)   If the Mortgage Loans are serviced by a person other than Seller (such
      third party the "Servicer"), Seller (i) shall, in accordance with Section
      (3)(b)(7), provide a copy of the servicing agreement to Buyer, which shall
      be in form and substance acceptable to Buyer (the "Servicing Agreement"),
      and shall provide a Servicer Notice to Buyer substantially in the form of
      Exhibit VII hereto, fully executed by Seller and the Servicer; and (ii)
      hereby irrevocably assigns to Buyer and Buyer's successors and assigns all
      right, title and interest of Seller in, to and under, and the benefits of,
      any Servicing Agreement with respect to the Mortgage Loans. Seller agrees
      that no Person shall assume the servicing obligations with respect to the
      Mortgage Loans as successor to the Servicer unless such successor is
      approved in writing by Buyer prior to such assumption of servicing
      obligations.

(d)   If the servicer of the Mortgage Loans is Seller, upon the occurrence of an
      Event of Default, Buyer shall have the right to terminate the Seller as
      servicer of the Mortgage Loans and transfer servicing to Buyer's
      designated Servicer, at no cost or expense to Buyer, at any time
      thereafter. If the Servicer of the Mortgage Loans is not Seller, Buyer

                                      -52-
<PAGE>

      shall have the right, as contemplated in the applicable Servicer Notice,
      upon the occurrence of an Event of Default, to terminate any applicable
      Servicing Agreement and transfer servicing to Buyer's designated Servicer,
      at no cost or expense to Buyer, it being agreed that Seller will pay any
      and all fees required to terminate such Servicing Agreement and to
      effectuate the transfer of servicing to Buyer's designated Servicer, as
      well as any servicing fees and expenses payable to such Servicer.

(e)   After the Purchase Date, until the repurchase of any Mortgage Loan, Seller
      will have no right to modify or alter the terms of such Mortgage Loan and
      Seller will have no obligation or right to repossess such Mortgage Loan or
      substitute another Mortgage Loan, in each case except as provided in the
      Custodial and Disbursement Agreement.

(f)   In the event Seller or its Affiliate is servicing the Mortgage Loans,
      Seller shall permit Buyer to inspect Seller's or its Affiliate's servicing
      facilities, as the case may be, for the purpose of satisfying Buyer that
      Seller or its Affiliate, as the case may be, has the ability to service
      the Mortgage Loans as provided in this Agreement.

25.   INTENT

(a)   The parties recognize that each Transaction is a "repurchase agreement" as
      that term is defined in Section 101 of Title 11 of the United States Code,
      as amended (except insofar as the type of Purchased Assets subject to such
      Transaction or the term of such Transaction would render such definition
      inapplicable), and a "securities contract" as that term is defined in
      Section 741 of Title 11 of the United States Code, as amended (except
      insofar as the type of Purchased Assets subject to such Transaction would
      render such definition inapplicable).

(b)   It is understood that either party's right to liquidate Purchased Assets

                REPRESENTATIONS AND WARRANTIES RE: MORTGAGE LOANS

                       PART I: RESIDENTIAL MORTGAGE LOANS

Seller represents and warrants to Buyer, with respect to each Mortgage Loan,
that the following representations are true as of the Purchase Date for the
purchase of any Purchased Assets by Buyer from Seller and as of the date of this
Agreement and any Transaction hereunder and at all times while the Repurchase
Documents and any Transaction hereunder is in full force and effect that the
following representations are true. For purposes of this Schedule 1 and the
representations and warranties set forth herein, a breach of a representation or
warranty shall be deemed to have been cured with respect to a Mortgage Loan if
and when Seller has taken or caused to be taken action such that the event,
circumstance or condition that gave rise to such breach no longer adversely
affects such Mortgage Loan.

      (1)   Mortgage Loans as Described. The information set forth in the Seller
            Asset Schedule is complete, true and correct;

      (2)   Payments Current. All payments required to be made up to the related
            Purchase Date for the Mortgage Loan under the terms of the Mortgage
            Note have been made and credited. No payment required under the
            Mortgage Loan is delinquent nor has any payment under the Mortgage
            Loan been delinquent for 30 days or more. The first and second
            Monthly Payments shall be made, or shall have been made, with
            respect to the Mortgage Loan on its Due Date or within the grace
            period, all in accordance with the terms of the related Mortgage
            Note;

      (3)   No Outstanding Charges. There are no defaults in complying with the
            terms of the Mortgage securing the Mortgage Loan, and all taxes,
            governmental assessments, insurance premiums, water, sewer and
            municipal charges, leasehold payments or ground rents which
            previously became due and owing have been paid, or an escrow of
            funds has been established in an amount sufficient to pay for every
            such item which remains unpaid and which has been assessed but is
            not yet due and payable. Except for (A) payments in the nature of
            escrow payments and (B) interest accruing from the date of the
            Mortgage Note or date of disbursement of the Mortgage proceeds,
            whichever is greater, to the day which precedes by one month the Due
            Date of the first installment of principal and interest, including,
            without limitation, taxes and insurance payments, Seller has not
            advanced funds, or induced, solicited or knowingly received any
            advance of funds by a party other than the Mortgagor, directly or
            indirectly, for the payment of any amount required under the
            Mortgage Loan;

      (4)   Original Terms Unmodified. The terms of the Mortgage Note and
            Mortgage have not been impaired, waived, altered or modified in any
            respect, except by a written instrument which has been recorded, if
            necessary to protect the interests of Buyer and which has been
            delivered to Custodian and the terms of which are reflected in the
            Seller Asset Schedule. The substance of any such waiver, alteration
            or

                                    Sch. 1-1
<PAGE>

            modification has been approved by the title insurer, to the extent
            required by the policy. No Mortgagor has been released, in whole or
            in part, except in connection with an assumption agreement approved
            by the title insurer, to the extent required by the policy, and
            which assumption agreement is part of the Mortgage File delivered to
            Custodian and the terms of which are reflected in the Seller Asset
            Schedule;

      (5)   No Defenses. The Mortgage Loan is not subject to any right of
            rescission, set-off, counterclaim or defense, including without
            limitation 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 without
            limitation the defense of usury, and no such right of rescission,
            set-off, counterclaim or defense has been asserted with respect
            thereto, and no Mortgagor was a debtor in any state or federal
            bankruptcy or insolvency proceeding at, or subsequent to, the time
            the Mortgage Loan was originated;

      (6)   Hazard Insurance. Pursuant to the terms of the Mortgage, all
            buildings or other improvements upon the Mortgaged Property are
            insured by a generally acceptable insurer 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
            insurance policies conforming to the requirements of Fannie Mae and
            Freddie Mac in an amount not less than the greater of (i) 100% of
            the replacement cost of all improvements to the Mortgaged Property
            or (ii) the outstanding principal balance of the Mortgage Loan, but
            in any event at least equal to the amount necessary to avoid the
            operation of any co-insurance provisions with respect to the
            Mortgaged Property, and consistent with the amount that would have
            been required as of the date of origination in accordance with that
            required by Fannie Mae and Freddie Mac. If upon origination of the
            Mortgage Loan, the Mortgaged Property was in an area identified in
            the Federal Register by the Federal Emergency Management Agency as
            having special flood hazards (and such flood insurance has been made
            available) a flood insurance policy meeting the requirements of the
            current guidelines of the Federal Flood Insurance Administration is
            in effect which policy conforms to the requirements of Fannie Mae
            and Freddie Mac. All individual insurance policies contain a
            standard mortgagee clause naming Seller and its successors and
            assigns as mortgagee, and all premiums thereon have been paid and
            such policies may not be reduced, terminated or cancelled without 30
            days' prior written notice to the mortgagee. The Mortgage obligates
            the Mortgagor thereunder to maintain the hazard insurance policy at
            the Mortgagor's cost and expense, and on the Mortgagor's failure to
            do so, authorizes the holder of the Mortgage to obtain and maintain
            such insurance at such Mortgagor's cost and expense, and to seek
            reimbursement therefor from the Mortgagor. Where required by state
            law or regulation, the Mortgagor has been given an opportunity to
            choose the carrier of the required hazard insurance, provided the
            policy is not a "master" or "blanket" hazard insurance policy
            covering the common facilities of a planned unit development.

            The hazard insurance policy is the valid and binding obligation of
            the insurer, is in full force and effect, and will be in full force
            and effect and inure to the benefit of Buyer upon the consummation
            of the transactions contemplated by this Agreement. Seller has not
            engaged in, and has no knowledge of the Mortgagor's or any
            subservicer's having engaged in, any act or omission which would
            impair the coverage of any such policy, the benefits of the
            endorsement provided for therein, or the validity and binding effect
            of either, including, without limitation, no unlawful fee,
            commission, kickback or other unlawful compensation or value of any
            kind has been or will be received, retained or realized by any
            attorney, firm or other person or entity, and no such unlawful items
            have been received, retained or realized by Seller;

      (7)   Compliance with Applicable Laws. Any and all requirements of any
            federal, state or local law including, without limitation, usury,
            truth-in-lending, real estate settlement procedures, consumer credit
            protection, equal credit opportunity or disclosure laws applicable
            to the Mortgage Loan including, without limitation, any provisions
            relating to prepayment fees, have been complied with, the
            consummation of the transactions contemplated hereby will not
            involve the violation of any such laws or regulations and Seller
            shall maintain in its possession, available for Buyer's inspection,
            and shall deliver to Buyer, upon demand, evidence of compliance with
            all such requirements;

      (8)   No Satisfaction of Mortgage. The Mortgage has not been satisfied,
            canceled, subordinated or rescinded, in whole or in part, and the
            Mortgaged Property has not been released from the lien of the
            Mortgage, in whole or in part, nor has any instrument been executed
            that would effect any such release, cancellation, subordination or
            rescission. Seller has not waived the performance by the Mortgagor
            of any action, if the Mortgagor's failure to perform such action
            would cause the Mortgage Loan to be in default, nor has Seller
            waived any default resulting from any action or inaction by the
            Mortgagor;

      (9)   Location and Type of Mortgaged Property. The Mortgaged Property is a
            fee simple property located in the state identified in the Seller
            Asset Schedule except with respect to real property located in
            jurisdictions in which the use of leasehold estates for residential
            properties is a widely-accepted practice, the mortgaged property
            consists of a single parcel of real property with a detached single
            family residence erected thereon, or a two- to four-family dwelling,
            an individual unit in a planned unit development, a unit in a
            condominium project or a dwelling situated on a leasehold estate
            (with respect to real property located in jurisdictions in which the
            use of leasehold estates for residential properties is a widely
            accepted practice) and no residence or dwelling thereon is (a)
            co-operative units, (b) log homes, (c) earthen homes, (d)
            underground homes, (e) mobile homes or manufactured housing units or
            (f) any dwelling situated on more than ten acres of property
            provided, however, that any planned unit development shall not fall
            within any of the "Ineligible Projects" of part XII, Section 102 of
            the Fannie Mae Selling Guide and shall conform with the Underwriting
            Guidelines. No portion of the Mortgaged Property is used for
            commercial purposes;

                                    Sch. 1-3

      (10)  Valid First or Second Lien. The Mortgage is a valid, subsisting,
            enforceable and perfected first or second lien and first or second
            priority security interest on the Mortgaged Property, including all
            buildings on the Mortgaged Property and all installations and
            mechanical, electrical, plumbing, heating and air conditioning
            systems located in or annexed to such buildings, and all additions,
            alterations and replacements made at any time with respect to the
            foregoing. The lien of the Mortgage is subject only to:

                        (A) the lien of current real property taxes and
                  assessments not yet due and payable;

                        (B) covenants, conditions and restrictions, rights of
                  way, easements and other matters of the public record as of
                  the date of recording acceptable to prudent mortgage lending
                  institutions generally and specifically referred to in the
                  lender's title insurance policy delivered to the originator of
                  the Mortgage Loan and (i) referred to or otherwise considered
                  in the appraisal made for the originator of the Mortgage Loan
                  or (ii) which do not adversely affect the appraised value of
                  the Mortgaged Property set forth in such appraisal;

                        (C) other matters to which like properties are commonly
                  subject which do not materially interfere with the benefits of
                  the security intended to be provided by the Mortgage or the
                  use, enjoyment, value or marketability of the related
                  Mortgaged Property; and

                        (D) with respect to each Second Lien Mortgage Loan a
                  prior mortgage lien on the Mortgaged Property.

            Any Security Agreement, chattel mortgage or equivalent document
            related to and delivered in connection with the Mortgage Loan
            establishes and creates a valid, subsisting and enforceable (A)
            first lien and first priority perfected security interest with
            respect to each First Lien Mortgage Loan, or (B) second lien and
            second priority perfected security interest with respect to each
            Second Lien Mortgage Loan, in either case, on the property described
            therein and Seller has full right to sell and assign the same to
            Buyer. The Mortgaged Property was not, as of the date of origination
            of the Mortgage Loan, subject to a mortgage, deed of trust, deed to
            secure debt or other security instrument creating a lien subordinate
            to the lien of the Mortgage;

      (11)  Validity of Mortgage Loan Documents. The Mortgage Note, the Mortgage
            and any other agreement executed and delivered by a Mortgagor or
            guarantor, if applicable, in connection with the Mortgage Loan are
            genuine, and each is the legal, valid and binding obligation of the
            maker thereof enforceable in accordance with its terms (including,
            without limitation, any provisions therein relating to prepayment
            fees). All parties to the Mortgage Note, the Mortgage and any other
            related agreement had legal capacity to enter into the Mortgage Loan
            and to execute and deliver the Mortgage Note, the Mortgage and any
            other related

                                    Sch. 1-4
<PAGE>

            agreement, and the Mortgage Note, the Mortgage and any other related
            agreement have been duly and properly executed by such parties. The
            documents, instruments and agreements submitted for loan
            underwriting were not falsified and contain no untrue statement of
            material fact or omit to state a material fact required to be stated
            therein or necessary to make the information and statements therein
            not misleading. No fraud, error, negligence, misrepresentation or
            omission of fact with respect to a Mortgage Loan has taken place on
            the part of Seller or the Mortgagor or any other party involved in
            the origination or servicing of the Mortgage Loan. Seller or its
            agent has reviewed all of the documents constituting the Servicing
            File and has made such inquiries as it deems necessary to make and
            confirm the accuracy of the representations set forth herein;

      (12)  Full Disbursement of Proceeds. The Mortgage Loan has been closed and
            the proceeds of the Mortgage Loan have been fully disbursed and
            there is no requirement for future advances thereunder, and any and
            all requirements as to completion of any on-site or off-site
            improvement and as to disbursements of any escrow funds therefor
            have been complied with. All costs, fees and expenses incurred in
            making or closing the Mortgage Loan and the recording of the
            Mortgage were paid, and the Mortgagor is not entitled to any refund
            of any amounts paid or due under the Mortgage Note or Mortgage;

      (13)  Ownership. Seller is the sole owner of record and holder of the
            Mortgage Loan. The Mortgage Loan is not assigned or pledged, and
            Seller has good, indefeasible and marketable title thereto, and has
            full right to transfer and sell the Mortgage Loan therein to Buyer
            free and clear of any encumbrance, equity, participation interest,
            lien, pledge, charge, claim or security interest, and has full right
            and authority subject to no interest or participation of, or
            agreement with, any other party, to sell and assign each Mortgage
            Loan pursuant to this Agreement and following the sale of each
            Mortgage Loan, Buyer will own such Mortgage Loan free and clear of
            any encumbrance, equity, participation interest, lien, pledge,
            charge, claim or security interest;

      (14)  Doing Business. All parties which have had any interest in the
            Mortgage Loan, whether as mortgagee, assignee, pledgee or otherwise,
            are (or, during the period in which they held and disposed of such
            interest, were) (1) in compliance with any and all applicable
            licensing requirements of the laws of the state wherein the
            Mortgaged Property is located, and (2) organized under the laws of
            such state, or (3) qualified to do business in such state, or (4)
            federal savings and loan associations or national banks having
            principal offices in such state, or (5) not doing business in such
            state;

      (15)  LTV; FICO. The Mortgage Loan does not have an LTV greater than 100%.
            At origination of the Mortgage Loan, the Mortgagor did not have a
            FICO score of less than 500.

      (16)  Title Insurance. The Mortgage Loan is covered by an ALTA lender's
            title insurance policy or other generally acceptable form of policy
            of insurance

                                    Sch. 1-5
<PAGE>

            acceptable to Fannie Mae or Freddie Mac, issued by a title insurer
            acceptable to Fannie Mae or Freddie Mac and qualified to do business
            in the jurisdiction where the Mortgaged Property is located,
            insuring Seller, its successors and assigns, as to the first or
            second priority lien of the Mortgage in the original principal
            amount of the Mortgage Loan, and against any loss by reason of the
            invalidity or unenforceability of the lien resulting from the
            provisions of the Mortgage providing for adjustment in the Mortgage
            Interest Rate and Monthly Payment, subject only to the exceptions
            contained in clauses (A), (B), and (C), and with respect to each
            Second Lien Mortgage Loan clause (D) of Paragraph (10) of this
            Schedule I. Where required by state law or regulation, the Mortgagor
            has been given the opportunity to choose the carrier of the required
            mortgage title insurance. Additionally, such lender's title
            insurance policy affirmatively insures ingress and egress, and
            against encroachments by or upon the Mortgaged Property or any
            interest therein. The title policy does not contain any special
            exceptions (other than the standard exclusions) for zoning and uses
            and has been marked to delete the standard survey exception or to
            replace the standard survey exception with a specific survey
            reading. Seller its successors and assigns is the sole insured of
            such lender's title insurance policy, and such lender's title
            insurance policy is in full force and effect and will be in force
            and effect upon the consummation of the transactions contemplated by
            this Agreement. No claims have been made under such lender's title
            insurance policy, and no prior holder or servicer of the Mortgage,
            including Seller, has done, by act or omission, anything which would
            impair the coverage of such lender's title insurance policy,
            including, without limitation, no unlawful fee, commission, kickback
            or other unlawful compensation or value of any kind has been or will
            be received, retained or realized by any attorney, firm or other
            Person, and no such unlawful items have been received, retained or
            realized by Seller;

      (17)  No Defaults. There is no default, breach, violation or event of
            acceleration existing under the Mortgage or the Mortgage Note and no
            event which, with the passage of time or with notice and the
            expiration of any grace or cure period, would constitute a default,
            breach, violation or event of acceleration, and neither Seller nor
            its predecessors have waived any default, breach, violation or event
            of acceleration. With respect to each Second Lien Mortgage Loan, (i)
            the prior mortgage is in full force and effect, (ii) there is no
            default, breach, violation or event of acceleration existing under
            such prior mortgage or the related mortgage note, (iii) no event
            which, with the passage of time or with notice and the expiration of
            any grace or cure period, would constitute a default, breach,
            violation or event of acceleration thereunder, and either (A) the
            prior mortgage contains a provision which allows or (B) applicable
            law requires, the mortgagee under the Second Lien Mortgage Loan to
            receive notice of, and affords such mortgagee an opportunity to cure
            any default by payment in full or otherwise under the prior
            mortgage;

      (18)  No Mechanics' Liens. There are no mechanics' or similar liens or
            claims which have been filed for work, labor or material (and no
            rights are outstanding that under the law could give rise to such
            liens) affecting the related Mortgaged

                                    Sch. 1-6
<PAGE>

            Property which are or may be liens prior to, or equal or coordinate
            with, the lien of the related Mortgage;

      (19)  Location of Improvements; No Encroachments. 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. No improvement
            located on or being part of the Mortgaged Property is in violation
            of any applicable zoning and building law, ordinance or regulation;

      (20)  Origination: Payment Terms. At the time the Mortgage Loan was
            originated, the originator was a mortgagee approved by the Secretary
            of Housing and Urban Development pursuant to Sections 203 and 211 of
            the National Housing Act or a savings and loan association, a
            savings bank, a commercial bank or similar banking institution which
            is supervised and examined by a Federal or State authority. No
            Mortgage Loan contains terms or provisions which would result in
            negative amortization. Principal payments on the Mortgage Loan
            commenced no more than 60 days after funds were disbursed in
            connection with the Mortgage Loan other than with respect to
            Interest-Only Loans. The Mortgage Interest Rate is adjusted, with
            respect to adjustable rate Mortgage Loans, on each Interest Rate
            Adjustment Date to equal the applicable index plus the Gross Margin
            (rounded up or down to the nearest 0.125%), subject to the Maximum
            Mortgage Interest Rate. The Mortgage Note is payable on the first
            day of each month in equal monthly installments of principal (other
            than with respect to Interest-Only Loans) and interest, which
            installments of interest, with respect to adjustable rate Mortgage
            Loans, are subject to change due to the adjustments to the Mortgage
            Interest Rate on each Interest Rate Adjustment Date, with interest
            calculated and payable in arrears, sufficient to amortize the
            Mortgage Loan fully by the stated maturity date (other than with
            respect to Interest-Only Loans), over an original term of not more
            than 30 years from commencement of amortization. The due date of the
            first payment under the Mortgage Note is no more than 60 days from
            the date of the Mortgage Note;

      (21)  Customary Provisions. The 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 provided thereby,
            including, (i) in the case of a Mortgage designated as a deed of
            trust, by trustee's sale, and (ii) otherwise by judicial
            foreclosure. Upon default by a Mortgagor on a Mortgage Loan and
            foreclosure on, or trustee's sale of, the Mortgaged Property
            pursuant to the proper procedures, the holder of the Mortgage Loan
            will be able to deliver good and merchantable title to the Mortgaged
            Property. There is no homestead or other exemption available to the
            Mortgagor which would interfere with the right to sell the Mortgaged
            Property at a trustee's sale or the right to foreclose the Mortgage
            subject to applicable federal and state laws and judicial precedent
            with respect to bankruptcy and right of redemption;

                                    Sch. 1-7
<PAGE>

      (22)  Conformance with Underwriting Guidelines and Agency Standards. The
            Mortgage Loan was underwritten in accordance with Seller's
            underwriting guidelines in effect at the time the Mortgage Loan was
            originated, a copy of which underwriting guidelines are attached as
            Exhibit II hereto. The Mortgage Note and Mortgage are on forms
            acceptable to Fannie Mae or Freddie Mac and Seller has not made any
            representations to a Mortgagor that are inconsistent with the
            mortgage instruments used;

      (23)  Occupancy of the Mortgaged Property. As of the related Purchase Date
            the Mortgaged Property is lawfully occupied under applicable law by
            the Mortgagor as its primary residence. 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. Seller has
            not received notification from any Governmental Authority that the
            Mortgaged Property is in material non-compliance with such laws or
            regulations, is being used, operated or occupied unlawfully or has
            failed to have or obtain such inspection, licenses or certificates,
            as the case may be. Seller has not received notice of any violation
            or failure to conform with any such law, ordinance, regulation,
            standard, license or certificate;

      (24)  No Additional Collateral. The Mortgage Note is not and has not been
            secured by any collateral except the lien of the corresponding
            Mortgage and the security interest of any applicable Security
            Agreement or chattel mortgage referred to in Paragraph (10) above;

      (25)  Deeds of Trust. In the event the Mortgage constitutes a deed of
            trust, a trustee, authorized and duly qualified under applicable law
            to serve as such, has been properly designated and currently so
            serves and is named in the Mortgage, and no fees or expenses are or
            will become payable by Custodian or Buyer to the trustee under the
            deed of trust, except in connection with a trustee's sale after
            default by the Mortgagor;

      (26)  Acceptable Investment. The Mortgagor is not in bankruptcy or
            insolvent and Seller has no knowledge of any circumstances or
            conditions with respect to the Mortgage, the Mortgaged Property, the
            Mortgagor or the Mortgagor's credit standing that can reasonably be
            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. No Mortgaged Property is located in a state,
            city, county or other local jurisdiction which the Buyer has
            determined in its sole good faith discretion (and so certified by
            notice to Seller prior to the applicable Purchase Date) would cause
            the related Mortgage Loan to be ineligible for whole loan sale or
            securitization in a transaction consistent with the prevailing sale
            and securitization industry (including, without limitation, the
            practice of the rating agencies) with respect to substantially
            similar mortgage loans;

            Buyer or its Custodian. Seller is in possession of a complete, true
            and accurate Mortgage File in compliance with Section 2 of the
            Custodial and Disbursement Agreement, except for such documents the
            originals of which have been delivered to Buyer or its Custodian;

            thereunder;

      (29)  Transfer of Mortgage Loans. The Assignment of Mortgage is in
            recordable form and is acceptable for recording under the laws of

      (30)  No Buydown Provisions; No Graduated Payments or Contingent
            Interests. The Mortgage Loan does not contain provisions pursuant to
            which Monthly Payments are paid or partially paid with funds
            deposited in any separate account established by Seller, the
            Mortgagor or anyone on behalf of the Mortgagor, or paid by any
            source other than the Mortgagor nor does it contain any other
            similar provisions currently in effect which may constitute a
            "buydown" provision. The Mortgage Loan is not a graduated payment
            mortgage loan and the Mortgage Loan does not have a shared
            appreciation or other contingent interest feature;

      (31)  Consolidation of Future Advances. Any future advances made prior to
            the related Purchase Date have been consolidated with the
            outstanding principal amount secured by the Mortgage, and the
            secured principal amount, as consolidated, bears a single interest
            rate and single repayment term. The lien of the Mortgage securing
            the consolidated principal amount is expressly insured as having
            first or second lien priority by a title insurance policy, an
            endorsement to the policy insuring the mortgagee's consolidated
            interest or by other title evidence acceptable to Fannie Mae and

      (32)  Mortgaged Property Undamaged. There is no proceeding pending or
            threatened for the total or partial condemnation of the Mortgaged

            earthquake or earth movement, windstorm, flood, tornado or other
            casualty so as to affect adversely the value of the Mortgaged
            Property as security for the Mortgage Loan or the use for which the
            premises were intended;

      (33)  Collection Practices; Escrow Deposits; Adjustable Rate Mortgage Loan

            Second Lien Mortgage Loans for which the mortgagee under the prior
            mortgage lien is collecting Escrow Payments), all such payments are
            in the possession of Seller and there exist no deficiencies in
            connection therewith for which customary arrangements for repayment
            thereof have not been made. Each Mortgage Loan is covered by a life

            remains unpaid and which has been assessed but is not yet due and
            payable. No escrow deposits or Escrow Payments or other charges or
            payments due Seller have been capitalized under the Mortgage or the
            Mortgage Note. All Mortgage Interest Rate adjustments have been made
            in strict compliance with state and federal laws and the terms of

            located, (ii) has no interest, direct or indirect, in the Mortgaged

            any environmental law, rule or regulation is an issue; and to the
            best of Seller's knowledge, nothing further remains to be done to

            fee, or other compensation has been or will be received by Seller or
            any designee of Seller or any corporation in which Seller or any

New York, NY 10019

Dear Sirs and Mesdames:

You have requested our opinion as counsel to [ ], a [ ] organized and existing
under the laws of [________________] (the "Seller"), with respect to certain
matters in connection with that certain Master Repurchase Agreement governing
purchases and sales of certain Mortgage Loans, dated as of August 25, 2004 (the
"Repurchase Agreement"), by and between Seller and CDC Mortgage Capital Inc.
(the "Buyer"), the Custodial and Disbursement Agreement, dated as of August 25,
2004 (the "Custodial and Disbursement Agreement"), among Seller, Buyer and
[___________]as custodian and disbursement agent Capitalized terms not otherwise
defined herein have the meanings set forth in the Repurchase Agreement.

            1.    the Repurchase Agreement;

            2.    the Custodial and Disbursement Agreement;

            4.    Letter Agreement, dated as of August 25, 2004 between Seller
                  and Buyer (the "Letter Agreement");

            3.    the Account Agreement;

            4.    unfiled copies of the financing statements listed on Schedule
                  1 (collectively, the "Financing Statements") naming Seller as
                  Debtor and Buyer as Secured Party and describing the Purchased
                  Items (as defined in the Master Repurchase Agreement) as to
                  which security interests may be perfected by filing under the
                  Uniform Commercial Code of the States listed on Schedule 1
                  attached hereto (the "Filing Collateral"), which I understand
                  will be filed in the filing offices listed on Schedule 1 (the
                  "Filing Offices");

            5.    the reports listed on Schedule 2 attached hereto as to UCC
                  financing statements (collectively, the "UCC Search Report");
                  and

            6.    such other documents, records and papers as we have deemed
                  necessary and relevant as a basis for this opinion.

            The Repurchase Agreement, the Account Agreement, the Letter
Agreement and the Custodial and Disbursement Agreement are hereinafter
collectively referred to as the "Governing Agreements." To the extent [we] [I]
have deemed necessary and proper, [we] [I] have relied upon the representations
and warranties of Seller contained in the Repurchase Agreement. [We] [I] have
assumed the authenticity of all documents submitted to me [us] as originals, the
genuineness of all signatures, the legal capacity of natural persons and the
conformity to the originals of all documents.

                                   Exh. III-1
<PAGE>

            Based upon the foregoing, it is [our] [my] opinion that:

            1. Seller is a limited liability company duly organized, validly
existing and in good standing under the laws of the [State of_____________] and
is qualified to transact business in, and is in good standing under, the laws of
the [State of ______________].

            2. The execution, delivery and performance by Seller of the
Governing Agreements to which it is a party, and the sales by Seller and the
pledge of the Purchased Items under the Repurchase Agreement have been duly
authorized by all necessary corporate action on the part of Seller. Seller has
all necessary corporate or other power, authority and legal right to enter into,
execute, deliver and perform its obligations under each of the Governing
Agreements. Each of the Governing Agreements have been duly executed and
delivered by Seller and are legal, valid and binding agreements enforceable in
accordance with their respective terms against Seller, subject to bankruptcy
laws and other similar laws of general application affecting rights of creditors
and subject to the application of the rules of equity, including those
respecting the availability of specific performance, none of which will
materially interfere with the realization of the benefits provided thereunder or
with Buyer's purchase of the Purchased Assets and/or security interest in the
Purchased Assets.

            3. No consent, approval, authorization or order of, and no filing or
registration with, any court or governmental agency or regulatory body is
required on the part of Seller for the execution, delivery or performance by
Seller of the Governing Agreements to which it is a party or for the sales by
Seller under the Repurchase Agreement or the sale of the Purchased Items to
Buyer and/or granting of a security interest to Buyer in the Purchased Items,
pursuant to the Repurchase Agreement.

            4. The execution, delivery and performance by Seller of, and the
consummation of the transactions contemplated by the Governing Agreements to
which it is a party do not and will not (a) violate any provision of Seller's
charter or by-laws, (b) violate any applicable law, rule or regulation, (c)
violate any order, writ, injunction or decree of any court or governmental
authority or agency or any arbitral award applicable to Seller or (d) result in
a breach of, constitute a default under, require any consent under, or result in
the acceleration or required prepayment of any indebtedness pursuant to the
terms of, any agreement or instrument to which Seller is a party or by which it
is bound or to which it is subject, or (except for the Liens created pursuant to
the Repurchase Agreement) result in the creation or imposition of any Lien upon
any Property of Seller pursuant to the terms of any such agreement or
instrument.

            5. There is no action, suit, proceeding or investigation pending or,
to the best of [our] [my] knowledge, threatened against Seller which, in [our]
[my] judgment, either in any one instance or in the aggregate, could be
reasonably likely to result in any material adverse change in the properties,
business or financial condition, or prospects of Seller or in any material
impairment of the right or ability of Seller to carry on its business
substantially as now conducted or in any material liability on the part of
Seller or which would draw into question the validity of the Governing
Agreements to which it is a party or the Mortgage Loans or of any action taken
or to be taken in connection with the transactions contemplated thereby, or
which could be reasonably likely to impair materially the ability of Seller to
perform under the terms of the Governing Agreements to which it is a party or
the Mortgage Loans.

                                   Exh. III-2
<PAGE>

            6. The Repurchase Agreement is effective to create, in favor of
Buyer, either a valid sale of the Purchased Items to Buyer or a valid security
interest under the Uniform Commercial Code in all of the right, title and
interest of Seller in, to and under the Purchased Items as collateral security
for the payment of Seller's obligations under the Repurchase Agreement, except
that (a) such security interests will continue in Purchased Items after its
sale, exchange or other disposition only to the extent provided in Section 9-315
of the Uniform Commercial Code, (b) the security interests in Purchased Items in
which Seller acquires rights after the commencement of a case under the
Bankruptcy Code in respect of Seller may be limited by Section 552 of the
Bankruptcy Code.

            7. When the Mortgage Notes are delivered to Custodian, endorsed in
blank by a duly authorized officer of Seller, the security interest referred to
in Section 6 above in the Mortgage Notes will constitute a fully perfected first
priority security interest in all right, title and interest of Seller therein.

            8. Assuming the Bank has (i) opened the Collection Account for the
benefit of Buyer and (ii) agreed to collect items therefor, Buyer, as the
customer with respect to the related Collection Account, will have a perfected
security interest therein under the Uniform Commercial Code.

            9. (a) Upon the filing of financing statements on Form UCC-1 naming
Buyer as "Secured Party" and Seller as "Debtor", and describing the Purchased
Items, in the jurisdictions and recording offices listed on Schedule 1 attached
hereto, the security interests referred to in Section 6 above will constitute
fully perfected security interests under the Uniform Commercial Code in all
right, title and interest of Seller in, to and under such Purchased Items, which
can be perfected by filing under the Uniform Commercial Code, or, will
demonstrate a completion of the sale of the Mortgage Loans to Buyer.

            (b) The UCC Search Report sets forth the proper filing offices and
the proper debtors necessary to identify those Persons who have on file in the
jurisdictions listed on Schedule 1 financing statements covering the Purchased
Items as of the dates and times specified on Schedule 2. The UCC Search Report
identifies no Person who has filed in any Filing Office a financing statement
describing the Purchased Items prior to the effective dates of the UCC Search
Report.

            10. Seller is not an "investment company", or a company "controlled"
by an "investment company," within the meaning of the Investment Company Act of
1940, as amended.

                                          Very truly yours,

      Re:   Collection Account established by Oak Street Mortgage LLC (the
            "Seller") at Deutsche Bank National Trust Company, a national
            banking association (the "Bank") pursuant to that certain Master
            Repurchase Agreement (as amended, supplemented or otherwise modified
            from time to time, the "Repurchase Agreement"), dated as of August
            25, 2004, between CDC Mortgage Capital Inc. (the "Buyer") and
            Seller.

Ladies and Gentlemen:

            Seller has entered into a Repurchase Agreement pursuant to which
Buyer may from time to time purchase mortgage loans (the "Purchased Assets")
secured by, among other things, the payments made by mortgagors on account of
Purchased Assets sold to Buyer under the Repurchase Agreement. As a requirement
of such transactions, upon a default or an event of default under the Repurchase
Agreement, all such payments are required to be forwarded daily to Buyer at the
Collection Account identified below within one (1) Business Day of receipt.

            Seller has established a collection account, Account No. [___], for
the account of Buyer, with the Bank, ABA# [_______________] (the "Collection
Account") which the Bank maintains in the name of, and in trust for, Buyer as
the Bank's customer. Seller has granted to Buyer a security interest in all
payments deposited in the Collection Account with respect to the Purchased
Assets sold to Buyer under the Repurchase Agreement.

            In the event the Bank receives notice from Buyer that a default or
an event of default has occurred and is continuing under the Repurchase
Agreement (a "Notice of Event of Default") from Buyer, the Bank shall in no
event (a) transfer funds from the Collection Account to Seller or any other
person other than pursuant to Buyer's direction, (b) act on the instruction of
Seller or any person other than Buyer or (c) cause or permit withdrawals from
the Collection Account in any manner not approved by Buyer in writing. Until
receipt of a Notice of an Event of Default, Seller shall be permitted to
withdraw funds or cause funds to be transferred from the Collection Account
without Buyer's approval.

                                    Exh. V-1
<PAGE>

            The Bank hereby waives any right that the Bank may now or hereafter
have to security interest, bank's or other possessory liens, rights to offset or
other claims against the funds in the Collection Account.

            In addition, the Bank acknowledges that (a) Seller has granted to
Buyer a security interest in all of Seller's right, title and interest in and to
any funds from time to time on deposit in the Collection Account with respect to
the Purchased Assets sold to Buyer under the Repurchase Agreement, (b) that such
funds are received by the Bank in trust for the benefit of Buyer and, except as
provided herein, are for application against Seller's obligations to Buyer, and
(c) that the Bank shall comply with Buyer's instructions regarding the
disposition of funds in the Collection Account without the consent of Seller
until the Bank receives notice from Buyer that it has released its lien on the
Collection Account and all funds deposited therein. The Bank shall be afforded
the same rights, protections, immunities and indemnities as the Custodian set
forth in [Section 13(a) and Section 14] of the Custodial and Disbursement
Agreement, dated as of August 25, 2004, among Seller, Buyer, Deutsche Bank
National Trust Company as custodian, and Deutsche Bank National Trust Company as
disbursement agent, as if specifically set forth herein.

            All bank statements in respect to the Collection Account shall be

                         FORM OF TRUE SALE CERTIFICATION

                           CERTIFICATE OF [PURCHASER]

            In connection with the transaction pursuant to the Master Repurchase
Agreement, dated as of August 25, 2004 between CDC Mortgage Capital Inc. and
[______] (the "Purchaser"), the undersigned certifies, on behalf of Purchaser
that:

            1. I personally participated as the __________ of the Purchaser in
the transaction (the "Transaction"), pursuant to which [NAME OF SELLING ENTITY]
(the "Seller") sold [DESCRIBE ASSETS] (the "Assets") to the Purchaser. In such
capacity, I reviewed the purchase and sale agreement relating to the Transaction
dated as of __________ __, 200_ (the "Purchase and Sale Agreement").

            2. Due to my close involvement in the Transaction, I can accurately
and diligently certify the facts listed herein on behalf of the Purchaser.

            3. Seller has shifted all of the risks and burdens which are
associated with the ownership of the Assets to the Purchaser.

            4. Seller has shifted all of the benefits and rewards which are
associated with the Assets to the Purchaser. Subsequent to the consummation of
the Transaction, Seller had no control rights with respect to the Assets, and
all legal rights and title with respect to the Assets vested in the Purchaser.

            5. There has been no recourse to Seller with respect to the
performance of the Assets.

            6. As of the date of the consummation of the Transaction, Seller
received from the Purchaser reasonably equivalent value for the transferred
Assets, in the form of [DESCRIBE CONSIDERATION].

            7. The Purchase and Sale Agreement represented the intention of
Seller and the Purchaser to accomplish a complete and irrevocable sale of the
Assets.

            8. Seller neither was obligated to repurchase, nor had any "call"
rights with respect to, the Assets.

            9. The Purchaser neither was obligated to sell the Assets back to
Seller, nor had any "put" rights with respect to the Assets.

            10. The Purchaser's books and records reflect that the Transaction
was a sale of the Assets, rather than a secured financing or a loan.

            11. The Purchaser treated the Transaction as a sale for accounting
and tax purposes.

            12. The Transaction was duly authorized by the Purchaser's officers
and directors, as required by the Purchaser's organizational documents and

Ladies and Gentlemen:

[SERVICER] (the "Servicer") is servicing certain mortgage loans for Seller
pursuant to certain [name servicing agreements] (the "Servicing Agreement")
between the Servicer and Seller. Pursuant to the Agreement between Buyer and
Seller, the Servicer is hereby notified that Seller has sold to Buyer certain
mortgage loans which are serviced by Servicer.

Upon receipt of a notice (a "Default Notice") from Buyer in which Buyer shall
(a) represent that a default or an event of default has occurred with respect to
Seller's obligations to Buyer and (b) identify the mortgage loans which are then
owned by Buyer under the Agreement (the "Mortgage Loans"), the Servicer shall
segregate all amounts collected on account of such Mortgage Loans, hold them in
trust for the sole and exclusive benefit of Buyer, and remit such collections in
accordance with Buyer's written instructions. Following receipt of such Default
Notice, Servicer shall follow the instructions of Buyer with respect to the
Mortgage Loans, and shall deliver to Buyer any information with respect to the
Mortgage Loans reasonably requested by Buyer.

Upon a receipt of a Default Notice, Buyer shall have the right to terminate the
Servicing Agreement and transfer servicing to its designee, at no cost or
expense to Buyer, and Seller shall pay any and all fees required to terminate
the Servicing Agreement and to effectuate the transfer of servicing to the
designee of Buyer.

Notwithstanding any contrary information which may be delivered to the Servicer
by Seller, the Servicer may conclusively rely on any information or Default
Notice delivered by Buyer, and Seller shall indemnify and hold the Servicer
harmless for any and all claims asserted against it for any actions taken in
good faith by the Servicer in connection with the delivery of such information
or Default Notice.
