      (11)  with respect to each Eligible Asset that is not a Wet-Ink Mortgage
            Loan, Buyer shall have received from Custodian on each Purchase Date

            Seller shall not permit, for any period of three (3) consecutive

(c)   This Agreement is not a commitment by Buyer to enter into Uncommitted
      Transactions with Seller but rather sets forth the procedures to be
      used in connection with periodic requests for Buyer to enter into
      Uncommitted Transactions with Seller. Seller hereby acknowledges that
      Buyer is under no obligation to agree to enter into, or to enter into,
      any Uncommitted Transaction pursuant to this Agreement. Seller shall
      request a Transaction by delivering to Custodian, Disbursement Agent
      and Buyer via Electronic Transmission a request in the form of
      Exhibit I attached hereto (a "Transaction Request") in accordance with
      the timeframe set forth in Section 3(a) of the Custodial and
      Disbursement Agreement. Such Transaction Request shall describe the
      Purchased Assets in a Seller Asset Schedule and set forth (i) the
      Purchase Date, (ii) the Purchase Price, (iii) the Repurchase Date,
      (iv) the Pricing Rate applicable to the Transaction, (v) the applicable
      Purchase Percentages, (vi) the applicable Class or Classes for each
      Mortgage Loan for which Seller is requesting the Transaction and
      (vii) additional terms or conditions not inconsistent with this
      Agreement.

      With respect to any request for an Uncommitted Transaction, unless
      otherwise agreed in writing, upon receipt of the Transaction Request,
      Buyer may, in its sole discretion, agree to enter into that portion of the
      requested Transaction representing a request for an Uncommitted
      Transaction, and such agreement shall be evidenced by a Confirmation to be
      delivered to Seller on the Purchase Date as described below.

      On each Purchase Date, Buyer shall forward to Seller a confirmation (a
      "Confirmation") by Electronic Transmission setting forth with respect to
      each Transaction funded on such date, (1) the mortgage loan number, (2)
      the Purchase Price for such Purchased Assets, (3) the Market Value of the
      related Mortgage Loans as of the date of such Confirmation, (4) the
      outstanding principal amount of the related Mortgage Loans, (5) the
      Repurchase Date, (6) the Pricing Rate and (7) the Class designations of
      such Purchased Assets. Buyer shall forward to Seller a revised
      Confirmation by Electronic Transmission notifying Seller as to any changes
      made by Buyer in the Pricing Spread, Purchase Percentage or Reduction
      Amount pursuant to the terms hereof.

      On each date that all the documents set forth in Section 2(a)(i) of the
      Custodial and Disbursement Agreement are received by the Custodian with
      respect to any Wet-Ink Mortgage Loan, and Custodian delivers to Buyer a
      Trust Receipt attaching an Asset Schedule and Exception Report with
      respect to such Eligible Assets, Buyer shall forward to Seller a new
      Confirmation by Electronic Transmission setting forth the following
      information, updated to reflect the revised Pricing Rate, and, if
      applicable, Market Value as a result of the conversion of such Mortgage
      Loan, (1) the mortgage loan number, (2) the Purchase Price for such
      Purchased Assets, (3) the Market Value of the related Mortgage Loans, (4)
      the outstanding principal amount of the related Mortgage Loans, (5) the
      Repurchase Date, (6) the Pricing Rate and (7) the Class designations of
      such Purchased Assets.

      In the event Seller disagrees with any terms of the Confirmation, Seller
      shall notify Buyer in writing of such disagreement within one (1) Business
      Day after receipt of such Confirmation unless a corrected Confirmation is
      sent by Buyer. An objection sent by Seller must state specifically that it
      is an objection, must specify the provision(s) being

                                      -28-
<PAGE>

      objected to by Seller, must set forth such provision(s) in the manner that
      Seller believes they should be stated, and must be received by Buyer no
      more than one (1) Business Day after the Confirmation was received by
      Seller.

(d)   Any Confirmation by Buyer shall be deemed to have been received by Seller
      on the date actually received by Seller.

(e)   Except as set forth in Section 3(c), each Confirmation, together with
      this Agreement, shall constitute conclusive evidence of the terms
      agreed between Buyer and Seller with respect to the Transaction to
      which the Confirmation relates, and Seller's acceptance of the related
      proceeds shall constitute Seller's agreement to the terms of such
      Confirmation. It is the intention of the parties that each Confirmation
      shall not be separate from this Agreement but shall be made a part of
      this Agreement.

(f)   On the Repurchase Date, termination of a Transaction will be effected
      by transfer to Seller or its designee of the Purchased Assets (and any
      Income in respect thereof received by Buyer not previously credited or
      transferred to, or applied to the obligations of, Seller pursuant to
      Section 5) which amount shall be netted against the simultaneous
      receipt of the Repurchase Price by Buyer. To the extent a net amount is
      owed to one party, the other party shall pay such amount to such party.
      Seller is obligated to obtain the Mortgage Files from Buyer or its
      designee (including Custodian) at Seller's expense on the Repurchase
      Date. Any payment made by Seller to repurchase Purchased Assets shall
      be first applied to repurchase Purchased Assets under Uncommitted
      Transactions until all outstanding Uncommitted Transactions have been
      terminated; it being understood that it is the intention of the parties
      hereto that at no time shall there be any outstanding Uncommitted
      Transactions when the aggregate amount of the Purchase Price with
      respect to all outstanding Committed Transactions is less than the
      Maximum Committed Amount.

(g)   Subject to the terms and conditions of this Agreement, during the term of
      this Agreement Seller may sell to Buyer, repurchase from Buyer Eligible
      Assets hereunder and resell to Buyer Repurchased Mortgage Loans that are
      Eligible Assets hereunder.

(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 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

                                      -29-
<PAGE>

      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,
      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 11 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 the original Escrow Instruction Letter to Custodian, for
      receipt by Custodian no later than ten (10) 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)   Seller agrees to pay to Buyer on the first Business Day following the
      6 month anniversary of the Effective Date and every 6 month anniversary
      thereafter, a non-use fee (the "Non-Use Fee"), equal to 10 basis points
      (0.10%) per annum on the average daily amount of the unutilized portion
      of the Maximum Committed Amount during the immediately ended 6-month
      period for which such payment is made, if the average daily amount of
      unutilized portion of the Maximum Committed Amount is in excess of 50%
      of the Maximum Committed Amount, 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.
      Notwithstanding the foregoing, Seller will not be obligated to pay a
      Non-Use Fee in connection with the failure to satisfy the condition set
      forth in Section 3(b)(20) or 3(b)(21).

                                      -30-

(n)   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(n)(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 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.

(o)   At the request of Seller made at least 90 days, but in no event earlier
      than 360 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.

                                      -31-

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 5 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 5 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 and shall be
      deemed to reduce the aggregate Purchase Price with respect to all
      outstanding Transactions.

(b)   Buyer's election, in its sole and absolute 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

                                      -32-
<PAGE>

      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 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, including without limitation 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) and 5(b) 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

                                      -33-
<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

                                      -34-
<PAGE>

      pursuant to any Servicing Agreement and all amounts on deposit therein,
      from time to time, all Purchase Agreements or other agreements or
      contracts relating to, constituting, or otherwise governing, any or all of
      the foregoing 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, the DDA Account and all monies from time to time on deposit in
      the DDA Account, the Check Disbursement Account and all monies from time
      to time on deposit in the Check Disbursement 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, each Seller Entity
      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 each Seller
      Entity hereby represents and warrants to Buyer that it is, a first
      priority perfected security interest. Each Seller Entity 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

                                      -35-
<PAGE>

      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.

(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.
      Nothing contained in this Agreement shall obligate Buyer to segregate any
      Purchased Assets and Purchased Items delivered to Buyer by Seller.

                                      -36-

10.   SELLER REPRESENTATIONS

      Each of the Seller Entities, jointly and severally, 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 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. None of the Seller
      Entities is 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 any Seller Entity to become insolvent,
      (ii) will not result in any Seller Entity 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 and Milestone Merchant Partners, 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 it cannot perform each and every covenant
      contained in the Repurchase Documents;

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

(f)   Legal Name; Existence; Organizational Identification Number. Each
      Seller Entity's exact legal name is, and for the immediately preceding
      four months has been, American Home Mortgage Corp., American Home
      Mortgage Investment Corp., American Home Mortgage Acceptance, Inc.,
      American Home Mortgage Holdings, Inc. or Columbia National,
      Incorporated, as applicable, or such other legal name with respect to a
      Seller Entity or Entities as may be provided to Buyer by such Seller
      Entity or Entities from time to time by not less than ten (10) days
      prior written notice to Buyer. Seller shall cooperate with Buyer in
      filing amendments to financing statements in connection with any such
      name changes. Each Seller Entity (i) is, and for the immediately
      preceding twelve months (or, if such Seller Entity was formed within
      the preceding twelve months, since the date of its formation) has been,
      a corporation duly organized, validly existing and in good standing
      under the laws of the jurisdiction of its incorporation; (ii) has all
      requisite

                                      -37-
<PAGE>

      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
      (iii) 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. The jurisdiction of incorporation and the
      corresponding organizational identification number for each Seller Entity
      are as set forth on Schedule 2 attached hereto.

(g)   Financial Condition. Seller has heretofore furnished to Buyer a copy of
      (a) AHMIC's consolidated balance sheet and the consolidated balance
      sheets of AHMIC's consolidated Subsidiaries for the fiscal year ended
      December 31, 2003, and the related AHMIC consolidated statements of
      income and retained earnings and of cash flows for AHMIC and AHMIC's
      consolidated Subsidiaries for such fiscal year, each audited by and
      with the unqualified opinion thereon of Deloitte and Touche LLP and
      (b) AHMIC's consolidated balance sheet and the consolidated balance
      sheets of AHMIC's consolidated Subsidiaries for the quarterly fiscal
      periods of AHMIC ended March 31, 2004 and the related consolidated
      statements of income and retained earnings and of cash flows for AHMIC
      and AHMIC's consolidated Subsidiaries for each 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 AHMIC and AHMIC's 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
      AHMIC and AHMIC's 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 any
      Seller Entity or any of its respective 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) makes a claim or claims in an
      aggregate amount greater than $1,500,000, 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 any Seller Entity 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 any Seller Entity or any of its
      respective Subsidiaries is a party or by which any of them or any of

                                      -38-
<PAGE>

      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 any
      Seller Entity or any of its respective Subsidiaries pursuant to the
      terms of any such agreement or instrument.

(j)   Action. Each Seller Entity 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; the execution, delivery and performance by it of each of the
      Repurchase Documents to which it is a party has 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 it, and constitutes a legal, valid and
      binding obligation of it enforceable against it in accordance with its
      terms.

(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 any Seller
      Entity of the Repurchase Documents to which it is a party 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.

(m)   Taxes. Each Seller Entity and its respective Subsidiaries have timely
      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 each
      Seller Entity and its respective Subsidiaries in respect of taxes and
      other governmental charges are, in the opinion of Seller, adequate.

(n)   Real Estate Investment Trust. AHMIC has not engaged in any material
      "prohibited transactions" as defined in Section 857(b)(6)(B)(iii) and
      (C) of the Code. AHMIC for its current "tax year" (as defined in the
      Code) is and for all prior tax years subsequent to its election to be a
      real estate investment trust has been entitled to a dividends paid
      deduction in accordance with the provisions of Section 857 of the Code
      with respect to any dividends paid by it with respect to each such year
      for which it has claimed or will claim a deduction in its Form
      1120-REIT filed or to be filed with the United States Internal Revenue
      Service for such year.

(o)   Investment Company Act. None of the Seller Entities nor any of their
      respective 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.

(p)   Purchased Assets.

      (1)   No Seller Entity has 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, the respective
            Seller Entity was the sole 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 a Seller Entity from an
            Affiliate of such Seller Entity unless a True Sale Certification has
            been delivered to Buyer or such Affiliate is a Seller Entity.

      (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.

      (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 Entity'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 fully perfected security interests
            under the Uniform Commercial Code in all right, title and interest
            of each Seller Entity 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.

(q)   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.

(r)   [Reserved].

(s)   Existing Financing Facilities. All credit facilities of each Seller
      Entity listed under the definition of "Existing Financing Facilities"
      are presently in effect. No defaults or events of default exist under
      any of the Existing Financing Facilities. The financial covenants
      hereunder are at least equal to those the applicable Seller Entity
      makes under each of the

                                      -40-
<PAGE>

      Existing Financing Facilities. Seller shall give Buyer prior notification
      if any amendment to any financial covenant in any Existing Financing
      Facility increases the obligations or requirements of Seller thereunder,
      and such changed financial covenant shall, with no further action of
      Seller or Buyer, automatically become a part hereof and be incorporated
      herein upon the effectiveness of such amendment in the other Existing
      Financing Facility.

(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 each Seller Entity or any of its respective
      Subsidiaries makes 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)   Servicing. CNI is the servicer of each Mortgage Loan.

(w)   No Reliance. Each Seller Entity 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.

(x)   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 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

                                      -41-
<PAGE>

      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.

(y)   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, each
      of the Seller Entities, jointly and severally, covenants that it will:

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

      (1)   as soon as available and in any event within forty-five (45)
            calendar days after the end of each calendar month, the unaudited
            consolidated balance sheets of American Home Mortgage Investment
            Corp. ("AHMIC") 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 AHMIC 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 AHMIC, which certificate
            shall state that said consolidated financial statements fairly
            present in all material respects the consolidated financial
            condition and results of operations of AHMIC 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 AHMIC, the consolidated balance
            sheets of AHMIC 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 AHMIC 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 AHMIC 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

            any Plan or Multiemployer Plan to which AHMIC 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 AHMIC setting forth details
            respecting such event or condition and the action, if any, that
            AHMIC or its ERISA 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 AHMIC or an ERISA Affiliate with respect to such

                  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

                  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;

                  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;

                  Multiemployer Plan by AHMIC 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 AHMIC 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

                  any Multiemployer Plan against AHMIC 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 AHMIC 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.

      AHMIC will furnish to Buyer, at the time AHMIC furnishes each set of
      financial statements pursuant to paragraphs (a)(1) and (a)(2) above, a
      certificate of a Responsible Officer of AHMIC to the effect that, to the
      best of such Responsible Officer's knowledge, AHMIC 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
      has obtained no knowledge of any Default or Event of Default except as
      specified in such certificate (and, if any Default or Event of Default has
      occurred and is continuing, describing the same in reasonable detail and
      describing the action AHMIC has taken or proposes to take with respect
      thereto).

(b)   Litigation. Seller will promptly, and in any event within ten (10) days
      after service of process on any of the following, give to Buyer notice
      of all litigation, actions, suits, arbitrations, investigations
      (including, without limitation, any of the foregoing which are
      threatened or pending) or other legal or arbitrable proceedings
      affecting any Seller Entity or any of their respective Subsidiaries or
      affecting any of the Property of any of them before any Governmental
      Authority that (i) questions or challenges the validity or
      enforceability of any of the Repurchase Documents or any action to be
      taken in connection with the transactions contemplated hereby,
      (ii) makes a claim or claims in an aggregate amount greater than
      $1,500,000, or (iii) which, individually or in the aggregate, if
      adversely determined, could be reasonably likely to have a Material
      Adverse Effect. Seller shall set forth on its monthly compliance report
      (in the form of Exhibit IX attached hereto) any such event requiring
      notice to Buyer under this Section 11(b).

(c)   Existence, etc. Each Seller Entity will:

      (1)   preserve and maintain its legal existence and all of its material
            rights, privileges, licenses and franchises necessary for the
            operation of its business (provided that nothing in this Section
            11(c)(1) shall prohibit any transaction expressly permitted under
            Section 11(d));

      (2)   comply with the requirements of all applicable laws, rules,
            regulations and orders of Governmental Authorities (including,
            without limitation, all environmental laws) if failure to comply
            with such requirements could be reasonably likely (either
            individually or in the aggregate) to have a Material Adverse Effect;

                                      -44-

            structure, each as described in Section 10(f) or (ii) change its
            jurisdiction of organization, unless it shall have provided Buyer
            thirty (30) days' prior written notice of such change and shall have
            first taken all action required by Buyer for the purpose of
            perfecting or protecting the lien and security interest of Buyer
            established hereunder;

      (5)   pay and discharge all taxes, assessments and governmental charges or

            Property prior to the date on which penalties attach thereto, except
            for any such tax, assessment, charge or levy the payment of which is
            being contested in good faith and by proper proceedings and against
            which adequate reserves are being maintained; and

      (6)   permit representatives of Buyer, upon reasonable notice (unless a
            Default shall have occurred and is continuing, in which case, no
            prior notice shall be required), during normal business hours, to
            examine, copy and make extracts from its books and records, to
            inspect any of its Properties, and to discuss its business and
            affairs with its officers, all to the extent reasonably requested by
            Buyer.

(d)   Prohibition of Fundamental Changes. Except with respect to the Bank
      Charter Event, no Seller Entity shall enter into any transaction of
      merger or consolidation or amalgamation, or liquidate, wind up or

      or sell all or substantially all of its assets; provided, that each
      Seller Entity may purchase all or substantially all of the assets
      and/or merge or consolidate with (i) any Affiliate or wholly owned
      subsidiary of it, or (ii) any other Person if it is the surviving
      corporation; and provided, further, that if after giving effect
      thereto, no Default would exist hereunder.

            adversely the Asset Value of such Purchased Asset;

      (5)   promptly upon any material change in the market value of any or all

            Material Adverse Effect; and

      (6)   promptly upon the occurrence of any default or event of default

                  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

                  from the sale of Purchased Assets applied to the Repurchase

                  (iii) any amounts applied to the Repurchase Price pursuant to
                  subsection (a)(4) of this Section 13); and

            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 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 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 affect the
            commercial reasonableness of any such sale of Purchased Assets.

(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 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

                                      -53-
<PAGE>

      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 or 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 and all initial set-up costs
      with the Custodian and the Disbursement Agent. Seller agrees to pay as
      and when billed by Buyer all of the out-of-pocket costs and expenses
      (including legal fees) incurred by Buyer in connection with the
      development, preparation and execution of any amendment, supplement or
      modification to this Agreement, any other Repurchase Document or any
      other documents prepared in connection therewith. Subject to the
      limitations set forth in Section 27, 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, including, but
      not limited to, those out of pocket costs and expenses incurred by
      Buyer pursuant to Sections 24 and 27.

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

                                      -54-
<PAGE>

      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

      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 or the other
      Repurchase Documents. 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

                                      -55-
<PAGE>

      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 any Seller Entity without the
      prior written consent of Buyer, and any attempted assignment without such
      consent shall be null and void. 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

      This Agreement may be terminated by (i) Seller (a) upon 30 days' written
      notice to Buyer upon payment to Buyer of the Termination Fee and (b) upon
      Buyer's unreasonable failure to approve a replacement facility (in which
      case such termination shall not cause Seller to incur any Non-Use Fee or
      Termination Fee) and (ii) Buyer upon 30 days' notice from Buyer to Seller
      upon the occurrence of the event set forth in Section 3(b)(20) or 3(b)(21)
      (in which case such termination shall not cause Seller to incur any
      Non-Use Fee or Termination Fee), except that this Agreement shall,
      notwithstanding termination, 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 and under this Section 20 with
      respect to the payment of the Termination Fee shall survive the
      termination of this Agreement.

21.   GOVERNING LAW

      THIS AGREEMENT SHALL BE GOVERNED AND CONSTRUED IN ACCORDANCE WITH THE LAWS
      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
            RESPECT THEREOF, TO THE EXCLUSIVE GENERAL JURISDICTION OF THE COURTS
            OF THE STATE OF NEW YORK SITTING IN THE BOROUGH OF MANHATTAN, 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
            BE EFFECTED BY MAILING A COPY THEREOF BY REGISTERED OR CERTIFIED
            MAIL (OR ANY SUBSTANTIALLY SIMILAR FORM OF MAIL), POSTAGE PREPAID,
            TO ITS ADDRESS SET FORTH UNDER ITS SIGNATURE BELOW OR AT SUCH OTHER
            ADDRESS OF WHICH BUYER SHALL HAVE BEEN NOTIFIED;

      (D)   AGREES THAT NOTHING HEREIN SHALL AFFECT THE RIGHT TO EFFECT SERVICE
            OF PROCESS IN ANY OTHER MANNER PERMITTED BY LAW OR SHALL LIMIT THE
            RIGHT TO SUE IN ANY OTHER JURISDICTION; AND

      (E)   WAIVES, TO THE FULLEST EXTENT PERMITTED BY APPLICABLE LAW, ANY AND
            ALL RIGHT TO TRIAL BY JURY IN ANY LEGAL PROCEEDING ARISING OUT OF OR
            RELATING TO THIS AGREEMENT, ANY OTHER REPURCHASE DOCUMENT OR THE
            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

                                      -57-
<PAGE>

      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 the
      Buyer substantially in the form of Exhibit VII hereto, fully executed
      by such Seller Entity 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 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
      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 Buyer's
      designated Servicer, as well as any servicing fees and expenses payable
      to such Servicer.

                                      -58-
<PAGE>

(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
      delivered to it in connection with Transactions hereunder or to exercise
      any other remedies pursuant to Section 16 hereof is a contractual right to
      liquidate such Transaction as described in Sections 555 and 559 of Title
      11 of the United States Code, as amended.

(c)   The parties agree and acknowledge that if a party hereto is an "insured
      depository institution," as such term is defined in the Federal Deposit
      Insurance Act, as amended ("FDIA"), then each Transaction hereunder is a
      "qualified financial contract," as that term is defined in FDIA and any
      rules, orders or policy statements thereunder (except insofar as the type
      of Purchased Assets subject to such Transaction would render such
      definition inapplicable).

(d)   It is understood that this Agreement constitutes a "netting contract"
      as defined in and subject to Title IV of the Federal Deposit Insurance
      Corporation Improvement Act of 1991 ("FDICIA") and each payment
      entitlement and payment obligation under any Transaction hereunder
      shall constitute a "covered contractual payment entitlement" or
      "covered contractual payment obligation", respectively, as defined in
      and subject to FDICIA (except insofar as one or both of the parties is
      not a "financial institution" as that term is defined in FDICIA or
      regulations promulgated thereunder).

26.   PERIODIC DUE DILIGENCE REVIEW

      Seller acknowledges that Buyer has the right to perform continuing due
      diligence reviews with respect to the Mortgage Loans, for purposes of
      verifying compliance with the representations, warranties and
      specifications made hereunder, or otherwise, and Seller agrees that upon
      reasonable (but no less than one (1) Business Day's) prior notice unless
      an Event of Default shall have occurred, in which case no notice is
      required, to Seller, Buyer or its authorized representatives will be
      permitted during normal business hours to

                                      -59-
<PAGE>

      examine, inspect, and make copies and extracts of, the Mortgage Files and
      any and all documents, records, agreements, instruments or information
      relating to such Mortgage Loans in the possession or under the control of
      Seller and/or Custodian. Seller also shall make available to Buyer a
      knowledgeable financial or accounting officer for the purpose of answering
      questions respecting the Mortgage Files and the Mortgage Loans. Without
      limiting the generality of the foregoing, Seller acknowledges that Buyer
      may purchase Mortgage Loans from Seller based solely upon the information
      provided by Seller to Buyer in the Seller Asset Schedule and the
      representations, warranties and covenants contained herein, and that
      Buyer, at its option, has the right at any time to conduct a partial or
      complete due diligence review on some or all of the Mortgage Loans
      purchased in a Transaction, including without limitation ordering new
      credit reports and new appraisals on the related Mortgaged Properties and
      otherwise re-generating the information used to originate such Mortgage
      Loan. Buyer may underwrite such Mortgage Loans itself or engage a mutually
      agreed upon third party underwriter to perform such underwriting. Seller
      agrees to cooperate with Buyer and any third party underwriter in
      connection with such underwriting, including, but not limited to,
      providing Buyer and any third party underwriter with access to any and all
      documents, records, agreements, instruments or information relating to
      such Mortgage Loans in the possession, or under the control, of Seller.
      Buyer shall pay all out-of-pocket costs and expenses incurred by Buyer in
      connection with Buyer's activities pursuant to this Section 26 ("Due
      Diligence Costs"); provided that,(i) in the event that a Default or an
      Event of Default shall have occurred or (ii) in the event that Buyer shall
      determine the need to confirm compliance with local, state or federal laws
      concerning the regulation of predatory lending practices, Seller shall
      reimburse Buyer for all Due Diligence Costs for any and all reasonable
      out-of-pocket costs and expenses incurred by Buyer in connection with
      Buyer's activities pursuant to this Section 26.

27.   BUYER'S APPOINTMENT AS ATTORNEY-IN-FACT

(a)   Seller hereby irrevocably constitutes and appoints Buyer and any
      officer or agent thereof, with full power of substitution, as its true
      and lawful attorney-in-fact with full irrevocable power and authority
      in the place and stead of Seller and in the name of Seller or in its
      own name, from time to time in Buyer's discretion, for the purpose of
      carrying out the terms of this Agreement, to take any and all
      appropriate action and to execute any and all documents and instruments
      which may be reasonably necessary or desirable to accomplish the
      purposes of this Agreement, and, without limiting the generality of the
      foregoing, Seller hereby gives Buyer the power and right, on behalf of
      Seller, without assent by, but with notice to, Seller, to do the
      following:

      (1)   in the name of Seller, or in its own name, or otherwise, to take
            possession of and endorse and collect any checks, drafts, notes,
            acceptances or other instruments for the payment of moneys due under
            any mortgage insurance or with respect to any other Purchased Items
            and to file any claim or to take any other action or proceeding in
            any court of law or equity or otherwise deemed appropriate by Buyer
            for the purpose of collecting any and all such moneys due under any
            such mortgage insurance or with respect to any other Purchased Items
            whenever payable;

                                      -60-
<PAGE>

      (2)   to pay or discharge taxes and Liens levied or placed on or
            threatened against the Purchased Items;

      (3)   (A) to direct any party liable for any payment under any Purchased
            Items to make payment of any and all moneys due or to become due
            thereunder directly to Buyer or as Buyer shall direct; (B) to ask or
            demand for, collect, receive payment of and receipt for, any and all
            moneys, claims and other amounts due or to become due at any time in
            respect of or arising out of any Purchased Items; (C) to sign and
            endorse any invoices, assignments, verifications, notices and other
            documents in connection with any Purchased Items; (D) to commence
            and prosecute any suits, actions or proceedings at law or in equity
            in any court of competent jurisdiction to collect the Purchased
            Items or any proceeds thereof and to enforce any other right in
            respect of any Purchased Items; (E) to defend any suit, action or
            proceeding brought against Seller with respect to any Purchased
            Items; (F) to settle, compromise or adjust any suit, action or
            proceeding described in clause (E) above and, in connection

Exception Report.

            Upon receipt of a Transaction Request and the related Seller Asset

by Custodian of a Fatal Document Exception, Custodian shall immediately send to
Seller, Disbursement Agent and Buyer, by Electronic Transmission, a Fatal
Document Exception Report listing such Fatal Document Exceptions together with
an Asset Schedule with respect to each Mortgage Loan that has any Fatal Document
Exception. Custodian's Electronic Transmission to each of Seller, Disbursement
Agent and Buyer of a Fatal Document Exception, shall be sent "confirm receipt"

with respect to a Wet-Ink Mortgage Loan on or before the tenth (10th) Business

as may be reasonably required by Buyer (the "Daily Aged Report"). Custodian

Report is delivered. Disbursement Agent shall provide to Custodian all
information in its possession that Custodian requires in order to complete and
deliver each Daily Aged Report. In no event shall Custodian list any Mortgage
Loan on an Asset Schedule and Exception Report if Custodian has not yet reviewed

            (c) Each Asset Schedule and Exception Report shall list all
Exceptions using such exception codes as are set forth on Annex 11 hereto, as
may be amended from time to time. In no event shall Custodian list any Mortgage
Loan on the Asset Schedule and Exception Report if such Mortgage Loan is
required to be listed on the Fatal Document Exception Report and related Asset
Schedule; provided that, if a Wet-Ink Mortgage Loan has been previously listed
on the Asset Schedule and Exception Report, it shall remain on the Asset
Schedule and Exception Report and the Custodian shall indicate any Fatal
Document Exception. The delivery of each Asset Schedule and Exception Report to
Buyer and Disbursement Agent shall be Custodian's representation that, other
than the Exceptions listed as part of the Exception Report: (i) all documents
required to be delivered in respect of each Mortgage Loan pursuant to Section 2
of this have been delivered and are in the possession of Custodian as part of
the Mortgage File for such Mortgage Loan, (ii) Custodian is holding each
Mortgage Loan identified on the Asset Schedule and Exception Report (except with
respect to MERS Designated Mortgage Loans), pursuant to this Agreement, as the
bailee of and custodian for Buyer and/or its designees, (iii) all such documents
have been reviewed by Custodian and appear on their face to be regular and to
relate to such Mortgage Loan and satisfy the requirements set forth in Section 2
of this Agreement and the review procedures attached hereto as Annex 4 (the
"Review Procedures"), (iv) the interest rate on the Mortgage Note or Credit Line
Agreement, as applicable, is the same as the amount specified in the related
Mortgage File and (v) with respect to Closed End Loans, the original principal
amount of the Mortgage Note, and with respect to HELOCs, the Credit Limit, as
applicable, are each accurately reflected in the documents in the Mortgage File,
and based upon a review of the Mortgage Note and Credit Line Agreement, as
applicable, items 6, 8 through 12, 14, 21, 22, 118 and 119 of Annex 1 as set
forth in the Seller Asset Schedule delivered by Seller to Custodian are correct.

            (d) In connection with an Asset Schedule and Exception Report
delivered hereunder by Custodian, Custodian shall make no representations as to
and shall not be responsible to verify (A) the validity, legality,
enforceability, due authorization, recordability, sufficiency, or genuineness of
any of the documents contained in each Mortgage File or (B) the collectability,
insurability, effectiveness or suitability of any such Mortgage Loan. Subject to
the following sentence, Seller and Buyer hereby give Custodian notice that from
and after the Purchase Date, Buyer shall own each Mortgage Loan identified on an
Asset Schedule and Exception Report until such time that Custodian receives
notice from Buyer or Disbursement Agent that Buyer no longer owns such Mortgage
Loan. In the event that Buyer does not purchase the Eligible Assets proposed to
be purchased from Seller prior to 5:00 p.m. New York time on such Purchase Date,
upon written notice thereof from Seller, acknowledged by Buyer, or notice from
Disbursement Agent thereof, Custodian shall hold or release to Seller, pursuant
to Seller's written instructions, the Mortgage Loans in respect of the Asset
Schedule and Exception Report delivered by Custodian on such Purchase Date.

            (e) Notwithstanding anything to the contrary set forth herein, in
the event that the Asset Schedule and Exception Report or detailed listing of
Wet-Ink Mortgage Loans attached to the Trust Receipt is different from the most
recently delivered Asset Schedule and Exception Report or detailed listing of
Wet-Ink Mortgage Loans, then the most recently delivered Asset Schedule and
Exception Report or detailed listing of Wet-Ink Mortgage Loans shall control and
be binding upon the parties hereto.

written instructions shall control.

            (c) In the event that (i) Buyer, any Seller Entity or Custodian
shall be served by a third party with any type of levy, attachment, writ or
court order with respect to any Mortgage File or any document included within a
Mortgage File or (ii) a third party shall institute any court proceeding by

all the Mortgage Files that are the subject of such proceedings pending a final,
nonappealable order of a court of competent jurisdiction permitting or directing

            Section 5. Release of Mortgage Files.

            (a) From time to time until Custodian is otherwise notified by Buyer
in writing (unless such notice is given by the Disbursement Agent in accordance
with Section 11), which notice shall be given by Buyer (or Disbursement Agent in
accordance with Section 11) only following the occurrence of a Default or an
Event of Default, Custodian shall, upon receipt of written request of Seller,
release documentation relating to Mortgage Loans in the possession of Custodian
to Seller or its designee, for the purpose of correcting documentary
deficiencies relating thereto against a Request for Release and Receipt
delivered via Electronic Transmission by Seller in the form of Annex 5-A hereto.
The preceding sentence respecting release to Seller, or its designee, of

clause (a) or (b) of this Section 5, Mortgage Files pertaining to Mortgage Loans
at the time being held by Custodian on behalf of Buyer with an aggregate
outstanding principal balance greater than $500,000 (the "Release Limit"). In

having released Mortgage Files pertaining to Mortgage Loans at the time being
held by Custodian on behalf of Buyer with an aggregate outstanding principal
balance greater than the Release Limit, Custodian shall notify Buyer and obtain
written consent of Buyer prior to such requested release. Custodian shall
promptly notify Buyer in its Daily Report that it has released any Mortgage File
to Seller or its designee. Seller or its designee shall hold each Mortgage File
delivered to it pursuant to this Section 5(a) as bailee for Buyer. Seller or its
designee shall return to Custodian each document previously released from
Custodian's Mortgage File within ten (10) Business Days of receipt thereof.
Seller hereby further covenants to Buyer and Custodian that any such request by
Seller for release of Mortgage Loan Documents pursuant to this Section 5(a)
shall be solely for the purposes of correcting clerical or other non-substantial
documentation problems in preparation for returning such Mortgage Loan Documents
to Custodian for ultimate sale or exchange and that Seller has requested such
release in compliance with all terms and conditions of such release set forth
herein and in the Repurchase Agreement. Notwithstanding anything to the contrary
contained in the foregoing, Mortgage Notes and Credit Line Agreements, as
applicable, shall be released only for the purpose of (i) ultimate sale or
exchange or (ii) presentation, collection, renewal or registration of transfer.

            (b) From time to time until Custodian is otherwise notified by Buyer

Request for Release of Documents and Receipt delivered via Electronic
Transmission in the form of Annex 5-B hereto, release to Seller or its designee
the Mortgage File or the documents set forth in such request relating to

operative only to the extent that at any time Custodian shall not have released
to Seller or its designee pursuant to clause (a) or (b) of this Section 5,
Mortgage Files pertaining to Mortgage Loans at the time being held by Custodian
on behalf of Buyer with an aggregate outstanding principal balance greater than
the Release Limit. In the event Seller or its designee requests the release of a
Mortgage File to Seller or its designee with respect to a Mortgage Loan, which
release would result in Custodian having released Mortgage Files pertaining to

aggregate outstanding principal balance greater than the Release Limit,
Custodian shall notify Buyer in its Daily Report and obtain written consent of
Buyer prior to such requested release. Custodian shall promptly notify Buyer

such release in compliance with all terms and conditions of such release set
forth herein and in the Repurchase Agreement. Notwithstanding anything to the
contrary contained in the foregoing, Mortgage Notes and Credit Line Agreements,
as applicable, shall be released only for the purpose of (i) ultimate sale or
exchange or (ii) presentation, collection, renewal or registration of transfer.

            (c) (i) From time to time Custodian is hereby authorized, upon
      receipt of a Request for Release in the form of Annex 5-C hereto delivered
      by Seller via Electronic Transmission and receipt of Buyers written
      consent to such release to release Mortgage Files in the possession of
      Custodian to a third party purchaser for the purpose of resale thereof.
      Buyer shall have no obligation to consent to any such Request for Release
      after the occurrence of a Default or an Event of Default. On such Request
      for Release, Seller shall indicate the Mortgage Loans to be sold, the
      purchase price for such Mortgage Loan anticipated to be received, the name
      and address of the third party purchaser, the preferred method of
      delivery, and the date of desired delivery.

            (ii) Any transmittal of documentation for Mortgage Loans in the
      possession of Custodian in connection with the sale thereof to a
      third-party purchaser other than an Agency will be under cover of a
      transmittal letter substantially in the form attached as Annex 12 hereto,
      duly completed by Custodian and executed by Custodian. Any transmittal of
      documentation for Mortgage Loans in the possession of Custodian in
      connection with the shipment to a custodian or trustee other than an
      Agency in connection with the formation of a mortgage pool supporting a
      mortgage-backed security (an "MBS") will be under cover of a transmittal
      letter substantially in the form attached as Annex 13 hereto. Promptly
      upon (x) the remittance by such third-party purchaser of the full purchase
      price of the Mortgage Loan or (y) the issuance of such MBS, Buyer shall
      notify Custodian in writing thereof.

            (iii) Any transmittal of documentation for Mortgage Loans in the
      possession of Custodian in connection with the sale thereof to an Agency
      will be under cover of Bailee Letter, duly completed by Custodian and
      executed by Custodian. Promptly upon the remittance by such Agency or the
      Seller of the full purchase price of the Mortgage Loan. With respect to
      any transmittal of documentation for Mortgage Loans in the possession of
      Custodian in connection with the shipment to an Agency, the Custodian
      shall verify (A) that the related Mortgage File contains the Applicable
      Agency Documents, (B) (1) with respect to the wire transfer instructions
      as set forth in Freddie Mac Form 987 (Wire Transfer Authorization for a
      Cash Warehouse Delivery) such wire transfer instructions are identical to
      Buyer's wire instructions to Seller or (2) the Payee Number set forth on
      Fannie Mae Form 1068 (Fixed-Rate, Graduated-Payment, or Growing-Equity
      Mortgage Loan Schedule) or Fannie Mae Form 1069 (Adjustable-Rate Mortgage
      Loan Schedule), as applicable, is identical to the Payee Number that has
      been identified by Buyer in writing as Buyer's Payee Number and (C) the
      Applicable Agency Documents list Buyer as sole subscriber. Seller
      covenants that it will advise Buyer of any necessary amendments to such
      exhibits to reflect all current requirements of the applicable Agency.
      Custodian shall immediately notify Buyer and Seller via Electronic
      Transmission (which shall be sent "confirm receipt" or by some other means
      such that Custodian has a reasonable belief that such notice has been
      received by the addressee) of any exception with respect to any exceptions
      to the requirements of the preceding sentence and such exception shall be
      a Fatal Document Exception with respect to such Mortgage Loan.

            (d) So long as no Default or Event of Default has occurred and is
continuing, Custodian and Buyer shall take such steps as they may reasonably be
directed from time to time by Seller in writing, which Seller deems necessary
and appropriate, to transfer promptly and

                                      -19-
<PAGE>

deliver to Seller any Mortgage File in the possession of Custodian relating to
any Mortgage Loan which was previously a Purchased Asset but which Seller, with
the written consent of Buyer, has notified Custodian has ceased to be an
Eligible Asset or the release of which would not cause Seller to violate Section
4 of the Repurchase Agreement. In furtherance of the foregoing, upon receipt of
written request from Seller in the form of Annex 5-A hereto delivered via
Electronic Transmission, which must be consented to by Buyer, Custodian shall
release to Seller the requested Mortgage Files.

            (e) Following written notification by Buyer (or Disbursement Agent
in accordance with Section 11) (which may be by facsimile) to Custodian that a
Default or an Event of Default has occurred and is continuing, Custodian shall
not release, or incur any liability to any Seller Entity or any other Person for
refusing to release, any item relating to a Purchased Asset to any Seller Entity
or any other Person without the express prior written consent and at the
direction of Buyer.

            (f) Custodian shall at all times monitor any release of Purchased
Assets under this Section 5, and shall track the period of time which has
elapsed for any such release of Purchased Assets and shall report such
information to Buyer daily and in the same manner as Custodian provides an Asset
Schedule and Exception Report.

            (g) Prior to any shipment of Mortgage Files hereunder, Seller shall
deliver to Custodian written instructions as to the method of shipment and
shippers Custodian is to utilize in connection with the transmission of Mortgage
Files or other loan documents in the performance of Custodian's duties
hereunder. Seller shall arrange for the provision of such services at its sole
cost and expense (or, at Custodian's option, reimburse Custodian for all costs
and expenses incurred by Custodian consistent with the instructions) and will
maintain such insurance against loss or damage to Mortgage Files or other loan
documents as Buyer deems appropriate. Without limiting the generality of the
provisions of Section 13(a), it is expressly agreed that in no event shall
Custodian have any liability for any losses or damages to any Seller Entity
arising out of actions of Custodian consistent with the instructions of Seller
except to the extent such losses or damages arise due to the Custodian's gross
negligence or willful misconduct. In the event Custodian does not receive such
written instructions, Custodian shall be authorized to utilize any nationally
recognized courier service.

            Section 6. Fees and Expenses of Custodian.

            Custodian shall charge such fees for its services under this
Agreement as are set forth in a separate agreement between Custodian and AHMC,
the payment of which fees, together with Custodian's expenses in connection
herewith, shall be solely the obligation of Seller. The failure of Seller to pay
any such fees shall not excuse the performance by Custodian of any of its
obligations hereunder. The obligations of Seller o pay Custodian such fees and
reimburse Custodian for such expenses in connection with services provided by
Custodian prior to the termination of this Agreement and the earlier of the
resignation or removal of Custodian shall survive such termination, resignation
or removal.

            Section 7. Removal or Resignation of Custodian and Disbursement
                       Agent.

            (a) Custodian or Disbursement Agent may at any time resign and
terminate their obligations under this Agreement upon at least (180) days' prior
written notice to Seller and Buyer. Promptly after receipt of notice of
Custodian's or Disbursement Agent's resignation, as applicable, Buyer shall
appoint, by written instrument, a successor custodian or a successor
disbursement agent, as applicable, subject to written approval by Seller (which
approval shall not be unreasonably withheld). One original counterpart of such
instrument of appointment shall be delivered to each of Seller, Custodian and
the successor custodian. In the event that no successor custodian or
disbursement agent shall have been appointed within such 180 day notice period,
Custodian or Disbursement Agent, as applicable, may petition any court of
competent jurisdiction to appoint a successor custodian or disbursement agent,
as the case may be.

            (b) Buyer, with the consent of Seller (which consent shall not be
unreasonably withheld), upon at least (30) days' prior written notice to
Custodian, Disbursement Agent and Seller, may remove and discharge Custodian (or
any successor custodian thereafter appointed) from the performance of its
obligations under this Agreement. Buyer, without the consent of Seller, upon at
least (30) days' prior written notice to Custodian, Disbursement Agent and
Seller, may remove and discharge Disbursement Agent (or any successor
disbursement agent thereafter appointed) from the performance of its obligations
under this Agreement. Promptly after the giving of notice of removal of
Custodian and Disbursement Agent, Buyer shall appoint, by written instrument, a
successor custodian, with the consent of Seller (which consent shall not be
unreasonably withheld), and a disbursement agent, which appointment shall
require no other approval. One original counterpart of such instrument of
appointment shall be delivered to each of Buyer, Seller, Custodian, Disbursement
Agent and the successor custodian and disbursement agent.

            (c) In the event of any such resignation or removal, Custodian shall
promptly transfer to the successor custodian, as directed in writing, all the
Mortgage Files being administered under this Agreement and, if the endorsements
on the Mortgage Notes or Credit Line Agreements, as applicable, and the
Assignments of Mortgage have been completed in the name of Custodian, assign the
Mortgages and endorse without recourse the Mortgage Notes Credit Line
Agreements, as applicable, to the successor Custodian or as otherwise directed
by Buyer. The cost of the shipment of Mortgage Files arising out of the
resignation of Custodian shall be at the expense of Custodian; provided,
however, that if the sole reason for Custodian's resignation is due to the
non-payment of the fees and expenses due to it hereunder by Seller, then the
shipment cost of such shipment of Mortgage Files shall not be an expense of
Custodian, but shall be at the expense of Seller. Any cost of shipment arising
out of the removal of Custodian shall be at the expense of Seller. Seller shall
be responsible for the fees and expenses of the successor custodian and the fees
and expenses for endorsing the Mortgage Notes and Credit Line Agreements, as
applicable, and assigning the Mortgages to the successor custodian if required
pursuant to this paragraph.

Custodian and at Seller's expense, Buyer, Seller and each of their respective
agents, accountants, attorneys and

                                      -21-

times during the existence of this Agreement and keep in full force and effect a
fidelity bond. All such insurance shall be in amounts, with standard coverage
and subject to standard deductibles, all as is customary for insurance typically
maintained by institutions which act as Disbursement Agents with duties similar
to those of Disbursement Agent herein. The minimum coverage under any such bond
and insurance policies shall be at least equal to the corresponding amounts
required by Fannie Mae or Freddie Mac in the Applicable Guide. A certificate of
an Authorized Representative of Disbursement Agent shall be furnished to Seller
and Buyer, upon written request, stating that such insurance is in full force
and effect.

      withdraw any funds from, the Wire-out Account. Funds retained in the
      Wire-out Account shall remain uninvested. Disbursement Agent shall
      reconcile the Wire-out Account on a daily basis. Upon written request of
      Buyer, Disbursement Agent shall verify the information contained on each
      wire instruction to the extent of confirming that the wire instructions on

      instructions set forth in the related Escrow Instruction Letter, Seller's

      Disbursement Agent shall be entitled to net any amounts due and owing
      under this Agreement to it or Custodian from Seller from amounts that,
      after application of amounts in the Settlement Account due and owing to
      Buyer, would otherwise be disbursed to Seller pursuant to this Section
      11(a)(iii). Unless Disbursement Agent shall receive notice in writing from
      Buyer to the contrary by 5:00 p.m. New York time on any applicable
      Business Day, Disbursement Agent is hereby authorized by Buyer to disburse
      funds deposited in the Settlement Account on such Business Day in

form and substance as determined by the Buyer and as is reasonably acceptable to
the Disbursement Agent. Each Customer Profile delivered by Buyer shall supersede
the previous Customer Profile and Disbursement Agent shall utilize the most
recently delivered Customer Profile on each day with respect to all transactions
hereunder. Promptly upon receipt of a Customer Profile, Disbursement Agent shall
verbally confirm with Buyer all changes to each field since the most recently
delivered Customer Profile.

            (c) Disbursement Agent Calculations and Verifications.

            (i) Initial Purchase of an Eligible Asset. With respect to each
      Eligible Asset, Disbursement Agent shall perform the procedures set forth
      below, in such order, with respect to each Eligible Asset in the order
      that the related Transaction Requests are received:

                  (A) On each date on which Disbursement Agent receives a
            Transaction Request from Seller, together with the related Seller
            Asset Schedule, Disbursement Agent shall verbally confirm the
            receipt of such Transaction Request with Buyer. With respect to each
            Transaction Request, Disbursement

                                      -25-

            Agent shall perform an Edit Check with respect to each Eligible
            Asset that Seller has requested Buyer purchase. If any Mortgage Loan
            fails the Edit Check Procedures, Disbursement Agent shall notify
            each of Seller and Buyer via Electronic Transmission (which shall be
            sent "confirm receipt" or by some other means such that Disbursement
            Agent has a reasonable belief that such notice has been received by
            the addressee) of such Fatal Information Exception, and such
            Transaction Request shall be deemed to be null and void.

                  (B) Upon a determination that each Eligible Asset that Seller
            has requested Buyer purchase does not fail the Edit Check,
            Disbursement Agent shall compare the information set forth in the
            related Seller Asset Schedule with the applicable information
            required pursuant to Annex 1 hereof with respect to the particular
            Class and shall notify each of Seller and Buyer via Electronic
            Transmission (which shall be sent "confirm receipt" or by some other
            means such that Disbursement Agent has a reasonable belief that such
            notice has been received by the addressee) of any Fatal Information
            Exception, and such Transaction Request shall be deemed to be null
            and void.

                  (C) Upon a determination that there is no Fatal Information
            Exception as set forth in clause (i) of the definition thereof,
            Disbursement Agent shall calculate the Purchase Price and Pricing
            Rate for each Eligible Asset to be purchased by Buyer pursuant to
            the Transaction Request using the information set forth in the
            Customer Profile. If the values calculated by Disbursement Agent do
            not match the values set forth in the related Transaction Request by
            Seller, Disbursement Agent shall notify each of Seller and Buyer via
            Electronic Transmission (which shall be sent "confirm receipt" or by
            some other means such that Disbursement Agent has a reasonable
            belief that such notice has been received by the addressee) of such
            Fatal Information Exception, and such Transaction Request shall be
            deemed to be null and void.

                  (D) Upon Disbursement Agent's determination that the
            Transaction Request sets forth the correct calculations of the
            related Purchase Price and Pricing Rate with respect to the
            Transaction, Disbursement Agent shall verify that, (i) after taking
            into account all purchase requests on the related Transaction
            Request, together with all other outstanding Transactions, that the
            aggregate Purchase Prices for each Class is equal to or less than
            the related Sub-Limits set forth in the Customer Profile and (ii)
            after giving effect to the requested Transaction that there would
            not be a Margin Deficit. If after giving effect to the purchases
            contemplated in the Transaction Request, the aggregate Purchase
            Prices of all such Transactions is greater than the Sub-Limits or
            the Margin Base, Disbursement Agent shall notify each of Seller and
            Buyer via Electronic Transmission (which shall be sent "confirm
            receipt" or by some other means such that Disbursement Agent has a
            reasonable belief that such notice has been received by the
            addressee) of such Fatal Information Exception, and such Transaction
            Request shall be deemed to be null and void.

                  (E) At the request of Buyer, Disbursement Agent shall verify
            the Wire Instructions set forth in the Seller Asset Schedule only to
            the extent of confirming that the Wire Instructions on the Asset
            Schedule delivered by Seller are to the DDA Account or are identical
            to the Wire Instructions set forth in the related Escrow Instruction
            Letter, Seller's Release or Warehouse Lender's Release, as
            applicable. Disbursement Agent shall be under no obligation to
            verify such wire instructions unless requested by Buyer.

                  (F) With respect to each Mortgage Loan other than a Check
            Funded Loan, upon a determination that giving effect to a
            Transaction Request would not cause a violation of any Sub-Limit or
            cause a Margin Deficit and receipt of an Asset Schedule and
            Exception Report from Custodian in accordance with Section 3 and
            receipt of the Fatal Document Exception Report, if any, from
            Custodian in accordance with Section 3, Disbursement Agent shall
            disburse funds in accordance with Section 11(d)(i). The disbursing
            of funds by Disbursement Agent shall constitute Disbursement Agent's
            certification that no Fatal Exception exists with respect to any
            Eligible Asset (or, with respect to a Wet-Ink Mortgage Loan, no
            Fatal Information Exception exists) funded pursuant to this Section
            11(c)(i)(F).

                  (G) With respect to each Check Funded Loan, upon (i) a
            determination that giving effect to a Transaction Request would not
            cause a violation of any Sub-Limit or cause a Margin Deficit, (ii)
            receipt of an Asset Schedule and Exception Report from Custodian in
            accordance with Section 3, (iii) receipt of the Fatal Document
            Exception Report, if any, from Custodian in accordance with Section
            3, and (iv) receipt from Seller of a Check Funding Schedule,
            Disbursement Agent shall on each Check Presentation Date (1) verify
            that checks in excess of the original principal balance with respect
            to any Check Funded Loan were not presented for payment and (2)
            determine the related Buyer Funded Amount. On the Check Presentation
            Date, in accordance with the Check Disbursement Agreement, on or
            prior to 12:00 noon, New York time, the Check Disbursement Bank
            shall deliver electronically to Disbursement Agent, Buyer and Seller
            the Check Presentment Report. Upon receipt of each Check Presentment
            Report, with respect to all checks listed on such Check Funding
            Schedule, Seller shall determine (i) the aggregate difference
            ("Seller Funded Amount") between the Purchase Price for the related
            Check Funded Loans and the amounts necessary to clear all such
            checks and (ii) the difference between the aggregate Buyer Funded
            Amount for such Check Funded Loan and the aggregate amount needed to
            fund all checks on such Check Presentation Date (the "Total Required
            Funds"). Upon receipt of the Seller Funded Amount and the Additional
            Seller Funded Amount, the Disbursement Agent shall disburse funds in
            accordance with Section 11(d)(ii). The disbursing of funds by
            Disbursement Agent shall constitute Disbursement Agent's
            certification that no Fatal Information Exception exists with
            respect to any Check Funded Loan funded pursuant to this Section
            11(c)(i)(G). No later than 11:00 a.m. New York time on the Check
            Reconciliation Date, pursuant to the Check Disbursement Agreement,
            Check Disbursement Bank shall make available to Disbursement Agent
            any Check

                                      -27-

            Funding Exceptions with respect to a check or a Check Funded Loan.
            Disbursement Agent shall review all Check Funding Exceptions
            received as of 11:00 a.m. New York time and notify Buyer via
            Electronic Transmission of any Check Funding Exceptions prior to
            1:00 p.m. New York time. Unless Buyer shall have notified
            Disbursement Agent in writing on or prior to 2:00 p.m. New York time
            that Disbursement Agent shall not issue a "no pay" instruction on
            any related check, Disbursement Agent shall issue a "no pay"
            instruction on any check with a Check Funding Exception except in
            the case of "Stop Suspect" Check Funding Exceptions, which
            Disbursement Agent shall not stop payment on unless notified by
            Seller or Buyer. At the request of Buyer, Disbursement Agent shall
            view the image of a check and verify that the payee set forth on the
            Check Funding Schedule matches the payee on such imaged check.
            Disbursement Agent shall track each check funded on respect of a
            Check Funded Loan and notify Buyer, pursuant to the Daily Report,
            when each check with respect to a Check Funded Mortgage Loan has
            been paid.

            (ii) Conversion of a Wet-Ink Mortgage Loan. On the date that
      Custodian receives a Seller Asset Schedule containing the information set
      forth on Annex 1 and all the documents set forth in Section 2(b) with
      respect to each Wet-Ink Mortgage Loan, pursuant to Section 3(a), Custodian
      shall deliver an Asset Schedule and Exception Report to each of Buyer and
      Disbursement Agent in accordance with Section 3(a). Upon Disbursement
      Agent's receipt of such Asset Schedule and Exception Report, Disbursement
      Agent shall perform the procedures set forth in Section 11(c)(i)(A)-(E) as
      if such conversion were a purchase of an Eligible Asset and if there are
      no Fatal Exceptions with respect to such Wet-Ink Mortgage Loan, the
      related Mortgage Loan shall no longer be a Wet-Ink Mortgage Loan.

            (iii) Request for Additional Transactions for Excess Margin. Upon
      Disbursement Agent's receipt of any Request for Additional Transactions
      for Excess Margin, Disbursement Agent shall perform the procedures set
      forth in Section 11(c)(i)(C) and (D) as if such request were a Transaction
      Request. Pursuant to Section 11(b) herein, Disbursement Agent shall
      utilize the most recently delivered Customer Profile in connection with
      such Request for Additional Transactions for Excess Margin. If, after
      performing such procedures, Disbursement Agent determines that giving
      effect to any such Request for Additional Transactions for Excess Margin
      would not cause a violation of any Sub-Limits or cause a Margin Deficit,
      Disbursement Agent shall fund any amounts required pursuant to Section
      11(d)(iv). The disbursing of funds by Disbursement Agent shall constitute
      Disbursement Agent's certification that no Fatal Exception exists with
      respect to any Eligible Asset (or, with respect to a Wet-Ink Mortgage
      Loan, no Fatal Information Exception exists).

            (d) Disbursements. If at any time Disbursement Agent is unable to
calculate the Purchase Prices in respect of disbursements to be made pursuant to
this Section 11(d) as a result of technical difficulties or otherwise, upon
written notice from Disbursement Agent to Buyer and Seller, Disbursement Agent
may request such information from Buyer. Additionally, if at any time Buyer
disputes Disbursement Agent's or Seller's calculation of the Purchase Prices in
respect of disbursements to be made pursuant to this Section 11(d), upon written
notice from

                                      -28-
<PAGE>

Buyer to Disbursement Agent and Seller, Disbursement Agent shall not disburse
funds as provided in this Section 11(d) until such dispute is resolved.

            (i) Disbursement in Respect of Purchases of Eligible Assets. On each
      proposed Purchase Date, Disbursement Agent will disburse funds in the
      Disbursement Account in accordance with the Wire Instructions in the
      Seller Asset Schedule within 2 hours of a final Transaction Request but in
      no event later than 5:15 p.m. New York time, provided that (A)
      Disbursement Agent shall have performed the procedures set forth in
      Section 11(c) and all conditions to disbursement set forth therein shall
      have been satisfied; (B) sufficient funds exist in the Disbursement
      Account (taking into account amounts required to be transferred from the
      related Wire-out Account pursuant to Section 11 (a)(ii)); (C) such
      instructions do not include any Seller Entity or any Affiliate of a Seller
      Entity as payee, unless otherwise authorized by Buyer in writing to
      Disbursement Agent; and (D) if a conflict exists between the instructions
      of Buyer and the instructions of Seller, Disbursement Agent shall follow
      Buyer's instructions. In the event that the funds maintained in the
      related Wire-out Account are not sufficient to permit the funding of the
      full Wire Amount for any Eligible Asset, no funds shall be disbursed from
      the Disbursement Account to fund or acquire such Eligible Asset. For each
      disbursement pursuant to this Section 11(d)(i), Disbursement Agent shall
      promptly notify Seller by Electronic Transmission of the related federal
      wire reference number when it becomes available.

            (ii) Disbursements in Respect of Check Funded Loans. On each Check
      Presentation Date, Disbursement Agent will disburse funds in the
      Disbursement Account to the DDA Account by 5:15 p.m. New York time,
      provided that (A) Disbursement Agent shall have performed the procedures
      set forth in Section 11(c) and all conditions to disbursement set forth
      therein shall have been satisfied; and (B) sufficient funds exist in the
      Disbursement Account (taking into account amounts required to be
      transferred from the related Wire-out Account pursuant to Section 11
      (a)(ii)). In the event that the funds maintained in the related Wire-out
      Account are not equal to the Total Required Funds for such Check
      Presentation Date, Disbursement Agent should disburse funds in accordance
      herewith and notify each of the Buyer and Seller of such shortfall via
      Electronic Transmission (which shall be sent "confirm receipt" or by some
      other means such that Disbursement Agent has a reasonable belief that such
      notice has been received by the addressee).

            (iii) [Reserved]

            (iv) Disbursements in Respect of Requests for Additional
      Transactions for Excess Margin. On the Business Day that Disbursement
      Agent determines that the provisions of Section 11(c)(iii) have been
      satisfied with respect to any Request for Additional Transactions for
      Excess Margin, Disbursement Agent shall withdraw from the Disbursement
      Account and credit to the Wire-out Account an amount equal to the
      requested amount of the Excess Margin.

            (e) [Reserved]

                                      -29-

            (f) Settlement. On the Business Day prior to the date on which
Seller intends to or is required to repurchase an Eligible Asset ("Intended
Repurchase Date") pursuant to the terms of the Repurchase Agreement (or a third
party purchases such Eligible Asset), Seller shall provide Disbursement Agent
and Buyer with written notice of all funds anticipated to be received by
Disbursement Agent from Seller (or such third party) for the credit of the
Settlement Account, together with a settlement report containing all information
set forth on Annex 17 hereto (the "Settlement Report") by 4:00 p.m. New York
time. Upon Disbursement Agent's verification that (x) all information required
pursuant to Annex 17 hereto is set forth in the Settlement Report, and (y) Buyer
has confirmed the accuracy of such Settlement Report in writing, which
confirmation may be delivered via Electronic Transmission, Disbursement Agent
shall immediately disburse such funds in the Settlement Account as directed in
the Settlement Report, provided (i) sufficient funds exist in the Settlement
Account, (ii) after giving effect to such repurchase, a Margin Deficit would not
exist and there would be no violation of any Sub-Limits and (iii) Buyer has not
disputed such disbursement prior to such disbursement. Disbursement Agent's
verification and Buyer's confirmation or disputation referenced in the preceding
sentence shall be completed, and written notice of any disputation shall be
given to Seller by Electronic Transmission, no later than 11:00 a.m. New York
time on the Intended Repurchase Date. If all amounts required to be disbursed to
Buyer pursuant to the Settlement Report are not deposited in the Settlement
Account by 4:00 p.m. New York time on the date indicated as the "Settlement
Date" in the Settlement Report, Disbursement Agent shall notify each of
Custodian, Seller and Buyer and it shall be deemed to constitute an Event of
Default under the Repurchase Agreement and satisfy all notice requirements of
Buyer with respect to an Event of Default and Custodian and Seller shall treat
such notice as a notice of an Event of Default from Buyer. Notwithstanding the
foregoing sentence, if sufficient funds are not deposited in the Settlement
Account in accordance with the preceding sentence on any "Settlement Date" and
there are funds on deposit in the Wire-out Account, Seller hereby agrees that,
and Disbursement Agent shall, transfer from the Wire-out Account to the
Settlement Account no later than 5:30 p.m. New York time on such date an amount
equal to the lesser of (x) all amounts on deposit in the Wire-out Account and
(y) such shortfall. If such transferred funds are sufficient to pay all amounts
required to be paid to Buyer pursuant to the Settlement Report, no Event of
Default shall be deemed to have occurred. Notwithstanding the foregoing, if a
conflict exists between the instructions of Buyer and the Settlement Report,
Disbursement Agent shall follow Buyer's instructions.

            (g) Reports; Monitoring.

            (i) On each Business Day, Disbursement Agent shall provide to Buyer
      a reconciliation report with respect to all cash activity in each
      Transaction Account. Additionally, upon request Disbursement Agent shall
      provide to Seller a reconciliation report with respect to all cash
      activity on the Wire-out Account and the Settlement Account.

            (ii) No later than 5:00 p.m. New York time on each Business Day,
      Disbursement Agent shall provide to Buyer a daily report setting forth
      such information as may reasonably be required by Buyer (a "Daily
      Report").

                                      -30-
<PAGE>

            (iii) Upon request of Buyer, Disbursement Agent shall provide to
      Seller a Daily Report reflecting the information set forth thereon as of
      the time of the transmission of such report.

            (iv) Disbursement Agent shall provide to Buyer any reports with
      respect to any aspect of the transactions contemplated by this Agreement,
      to the extent the requested information is, or should be, in the
      possession of Disbursement Agent, as Buyer may request.

            (v) Disbursement Agent shall track and monitor all information
      required to be provided to any party hereunder pursuant to any report
      required to be delivered hereunder, including but not limited to, (A) all
      amounts funded in respect of any Mortgage Loan, including, without
      limitation, the Purchase Price, (B) the date such funds were disbursed,
      (C) all amounts due to Buyer in respect of the Periodic Advance Repurchase
      Payment, (D) the amount of any distribution in connection with any Request
      for Additional Transactions for Excess Margin, (E) all Purchased Assets
      and the aggregate outstanding Repurchase Prices in respect thereof and (F)
      the amount of any Margin Deficit or Excess Margin.

            (vi) Disbursement Agent shall provide all information in its
      possession to Custodian, to the extent Custodian requests, in order to
      permit Custodian to comply with its requirements under this Agreement,
      including, but not limited to, the preparation and delivery of each
      updated Asset Schedule, Exception Report and Fatal Exception Report.

            (h) Income Payment Dates. Notwithstanding that Buyer and Seller
intend that the Transactions under the Repurchase Agreement and hereunder to be
sales to Buyer of the Purchased Assets, Seller shall deposit into the Settlement
Account the Periodic Advance Repurchase Payment on each Payment Date. On each
Payment Date, Buyer shall forward to Disbursement Agent a payment date report in
the form set forth on Annex 19 hereto (a "Payment Date Report"). Disbursement
Agent shall verify that all amounts required to be paid to Buyer pursuant to the
Payment Date Report are deposited into the Settlement Account on each Payment
Date. If such amounts are not deposited into the Settlement Account on or prior
to 5:00 p.m. New York time on such Payment Date, Disbursement Agent shall notify
each of Custodian, Seller and Buyer and it shall be deemed to constitute an
Event of Default under the Repurchase Agreement and satisfy all notice
requirements of Buyer with respect to an Event of Default and Custodian and
Seller shall treat such notice as a notice of an Event of Default from Buyer.

            (i) Set-off. Custodian and Disbursement Agent agree that they shall
not exercise any right of set-off, banker's lien or any similar right in
connection with funds on deposit in any Transaction Account.

            (j) Fees and Expenses of Disbursement Agent.

            (i) Disbursement Agent shall charge such fees for its services under
      this Agreement as are set forth in a separate agreement between
      Disbursement Agent and AHMC, the payment of which fees, together with
      Disbursement Agent's expenses in connection herewith, shall be solely the
      obligation of Seller. The failure of Seller to pay

                                      -31-
<PAGE>

      any such fees shall not excuse the performance by Disbursement Agent of
      any of its obligations hereunder. The obligations of the Seller to pay
      Disbursement Agent such fees and reimburse Disbursement Agent for such
      expenses in connection with services provided by Disbursement Agent prior
      to the termination of this Agreement and the earlier of the resignation or
      removal of Disbursement Agent shall survive such termination, resignation
      or removal.

            (ii) Seller shall be responsible for the standard fees and charges
      of Disbursement Agent applicable to each Transaction Account. To the
      extent that Seller has not paid such fees within a reasonable amount of
      time from Seller's receipt of notice of such fees and charges,
      Disbursement Agent shall provide written notice to Buyer of Seller's
      failure to pay such fees and Buyer shall have the option, in its sole
      discretion, to cure such failure.

            (k) In performing its obligations under this Section 11, except as
specifically provided in this Agreement, Disbursement Agent will not follow
instructions from any party other than Buyer.

            Section 12. No Adverse Interest.

            By execution of this Agreement, each of Disbursement Agent and
Custodian represent and warrant that it currently holds, and during the
existence of this Agreement shall hold, no adverse interest, by way of security
or otherwise, in any Mortgage Loan, and hereby waives and releases any such
interest which it may have in any Mortgage Loan as of the date hereof. The
Mortgage Loans shall not be subject to any security interest, lien or right to
set-off by Custodian, Disbursement Agent or any third party claiming through
Custodian or Disbursement Agent, and neither Custodian nor Disbursement Agent
shall pledge, encumber, hypothecate, transfer, dispose of, or otherwise grant
any third party interest in, the Mortgage Loans.

            Section 13. Indemnification.

            (a) Each Seller Entity, jointly and severally, agrees to indemnify
and hold Custodian, Disbursement Agent and their affiliates, directors,
officers, agents and employees harmless against any and all liabilities,
obligations, losses, damages, penalties, actions, judgments, suits, costs, of
any kind or nature whatsoever, including reasonable attorney's fees, that may be
imposed on, incurred by, or asserted against it or them in any way relating to
or arising out of this Agreement or any action taken or not taken by it or them
hereunder unless such liabilities, obligations, losses, damages, penalties,
actions, judgements, suits, cost, expenses or disbursements were imposed on,
incurred by or asserted against Custodian or Disbursement Agent because of the
breach by Custodian or Disbursement Agent, as applicable, of its obligations
hereunder, which breach was caused by negligence, lack of good faith or willful
misconduct on the part of Custodian or Disbursement Agent, as applicable or any
of its respective directors, officers, agents or employees. Each of Disbursement
Agent and Custodian agree that it will promptly notify Seller of any such claim,
action or suit asserted or commenced against it and that Seller may assume the
defense thereof with counsel reasonably satisfactory to Disbursement Agent or
Custodian, as applicable, at Seller's sole expense, that Custodian or

Disbursement Agent, as applicable, will cooperate with Seller on such defense,
and that Custodian or Disbursement Agent, as applicable, will not settle any
such claim, action or suit without the consent of Seller. The foregoing
indemnification shall survive any resignation or removal of Custodian or
Disbursement Agent, as applicable, or the termination or assignment of this
Agreement.

            (b) In the event that Custodian fails to produce a Mortgage Note, a
Credit Line Agreement, an Assignment of Mortgage or any other document related
to a Mortgage Loan that was in its possession pursuant to Section 2 within two
(2) Business Days after required or requested by Seller or Buyer, and provided
that (i) Custodian previously delivered to Buyer an Asset Schedule and Exception
Report which did not list such document as an Exception on the related Purchase
Date; (ii) such document is not outstanding pursuant to a Request for Release
and Receipt in the form annexed hereto as either Annex 5-A or Annex 5-B; and
(iii) such document was held by Custodian on behalf of Seller or Buyer, as
applicable (a "Custodial Delivery Failure"), then Custodian shall (a) with
respect to any missing Mortgage Note or Credit Line Agreement, as applicable,
promptly deliver to Buyer or Seller upon request, a Lost Note Affidavit in the
form of Annex 16 hereto and (b) with respect to any missing document related to
such Mortgage Loan, including but not limited to a missing Mortgage Note or
Credit Line Agreement, as applicable, (1) indemnify Seller and Buyer, as
applicable, in accordance with Section 13(c) below and (2) at Buyer's option, at
any time the long term obligations of Custodian are rated below the second
highest rating category of Moody's Investors Service, Inc. or Standard and
Poor's Ratings Group, a division of McGraw-Hill, Inc., obtain and maintain, at
Custodian's expense, an insurance bond in the name of Buyer, and its successors
in interest and assigns, insuring against any losses associated with the loss of
such document, in an amount equal to the then outstanding principal balance of
the related Mortgage Loan or such lesser amount requested by Buyer in Buyer's
sole discretion.

            (c) Custodian agrees to indemnify and hold Buyer and each Seller
Entity, and each of their respective present or former affiliates, directors,
officers, employees, agents and representatives harmless against any and all
liabilities, obligations, losses, damages, penalties, actions, judgments, suits,
costs, expenses or disbursements of any kind or nature whatsoever, including
reasonable attorney's fees, that may be imposed on, incurred by, or asserted
against it or them in any way relating to or arising out of a Custodial Delivery
Failure or Custodian's breach of this Agreement, negligence, lack of good faith
or willful misconduct. The foregoing indemnification shall survive the
resignation or removal of Custodian and any termination or assignment of this
Agreement.

            (d) Disbursement Agent agrees to indemnify and hold Buyer and each
Seller Entity, and each of their respective present or former affiliates,
directors, officers, employees, agents and representatives harmless against any
and all liabilities, obligations, losses, damages, penalties, actions,
judgments, suits, costs, expenses or disbursements of any kind or nature
whatsoever, including reasonable attorney's fees, that may be imposed on,
incurred by, or asserted against it or them in any way relating to or arising
out of Disbursement Agent's breach of this Agreement, negligence, lack of good
faith or willful misconduct. The foregoing indemnification shall survive the
resignation or removal of Disbursement Agent or any termination or assignment of
this Agreement.

            Section 14. Reliance of Custodian.

            (a) In the absence of bad faith on the part of Custodian or
Disbursement Agent, Custodian and Disbursement Agent may each conclusively rely,
as to the truth of the statements and the correctness of the opinions expressed
therein, upon any request, instruction, certificate, opinion or other document
furnished to Custodian or Disbursement Agent (including such items received via
Electronic Transmission), reasonably believed by Custodian or Disbursement Agent
, as applicable, to be genuine and to have been signed or presented by the
proper party or parties and conforming to the requirements of this Agreement;
provided, however, that in the case of any Mortgage Loan Document or other
request, instruction, document or certificate which by any provision hereof is
specifically required to be furnished to Custodian or Disbursement Agent,
Custodian or Disbursement Agent , as applicable, shall be under a duty to
examine the same in accordance with the requirements of this Agreement.

            (b) Custodian shall have no duties or responsibilities except those
that are specifically set forth in this Agreement. Custodian shall have no
responsibility nor duty with respect to any Mortgage File while not in its
possession. If Custodian requests instructions from Buyer with respect to any
act, action or failure to act in connection with this Agreement, Custodian shall
be entitled to refrain from taking such action and continue to refrain from
acting unless and until Custodian shall have received written instructions from
Buyer with respect to a Mortgage File without incurring any liability therefor
to Buyer or any other Person.

            (c) Other than as provided herein, neither Custodian nor any of its
directors, officers, agents or employees shall be liable for any action or
omission to act hereunder except for its or their own negligence or lack of good
faith or willful misconduct. In no event shall Custodian or any of its
directors, officers, agents or employees have any responsibility to ascertain or
take action except as expressly provided herein.

            (d) Neither Custodian nor any of its directors, officers, agents or
employees shall be liable to the Purchaser or any other Person with respect to
any action taken or not taken by it in good faith in the performance of its
obligations under this Agreement. The obligations of Custodian or any of its
directors, officers, agents or employees shall be determined solely by the
express provisions of this Agreement.

            (e) Custodian may consult with counsel selected by Custodian with
regard to legal questions arising out of or in connection with this Agreement,
and the advice or opinion of such counsel shall be full and complete
authorization and protection in respect of any action reasonably taken, omitted
or suffered by Custodian in good faith and in accordance therewith; provided
such action shall be in compliance with all the terms expressly provided herein.

            (f) No provision of this Agreement shall require Custodian to expend
or risk its own funds or otherwise incur financial liability (other than
expenses or liabilities otherwise required to be incurred by the express terms
of this Agreement) in the performance of its duties under this Agreement if it
shall have reasonable grounds for believing that repayment of such funds or
adequate indemnity is not reasonably assured to it.

                                      -34-

            (g) Any corporation into which Custodian may be merged or converted
or with which it may be consolidated, or any corporation resulting from any
merger, conversion or consolidation to which Custodian shall be a party, or any
corporation succeeding to the business of Custodian shall be the successor of
Custodian hereunder without the execution or filing of any paper with any party
hereto or any further act on the part of any of the parties hereto except where
an instrument of transfer or assignment is required by law to effect such
succession, anything herein to the contrary notwithstanding.

            Section 15. Term of Agreement.

            Promptly after written notice from Buyer of the termination of the
Repurchase Agreement and payment in full of all amounts owing to Buyer
thereunder, Custodian shall deliver all documents remaining in the Mortgage
Files to Seller, and, except as otherwise set forth herein, this Agreement shall
thereupon terminate.

            Section 16. Notices.

            All demands, notices and communications hereunder shall be in
writing and shall be deemed to have been duly given when received by the
recipient party at the address shown on its signature page hereto, or at such
other addresses as may hereafter be furnished to each of the other parties by
like notice. Any such demand, notice or communication hereunder shall be deemed
to have been received on the date delivered to or received at the premises of
the addressee. Each party hereto hereby represents and warrants that its office
is located at the respective address set forth on its signature page hereto, and
each such party shall notify each other party hereto if such address should

OF NEW YORK WITHOUT GIVING EFFECT TO THE CONFLICT OF LAW PRINCIPLES THEREOF.

            Section 18. Authorized Representatives.

            Each individual designated as an authorized representative of Buyer
or its successors or assigns, any Seller Entity, Disbursement Agent and
Custodian, respectively (an "Authorized Representative"), is authorized to give
and receive notices, requests and instructions and to deliver certificates and
documents in connection with this Agreement on behalf of Buyer, Seller,
Disbursement Agent and Custodian, as the case may be, and the specimen signature
for each such Authorized Representative, initially authorized hereunder, is set
forth on Annexes 6, 7, 8 and 9 hereof, respectively. From time to time, Buyer,
each Seller Entity, Disbursement Agent and Custodian or their respective
successors or permitted assigns may, by delivering to the others a revised
annex, change the information previously given pursuant to this Section 18, but
each of the parties hereto shall be entitled to rely conclusively on the then
current annex until receipt of a superseding annex.

            Section 20. Cumulative Rights.

            The rights, powers and remedies of Custodian, Disbursement Agent and
Buyer under this Agreement shall be in addition to all rights, powers and
remedies given to Custodian, Disbursement Agent and Buyer by virtue of any
statute or rule of law, the Repurchase Agreement or any other agreement, all of
which rights, powers and remedies shall be cumulative and may be exercised
successively or concurrently without impairing Buyer's interest in the Purchased
Assets.

            Section 21. Assignment; Binding upon Successors.

            This Agreement may not be assigned in whole or in part by Seller,
Custodian or Disbursement Agent without the prior written consent of Buyer. This
Agreement may be assigned by Buyer in whole or in part without the prior written
consent of any other party hereto. Buyer shall provide Custodian with notice of
such assignment together with written acknowledgment that the assignee is
assuming all of the obligations of Buyer under this Agreement to the extent
applicable. All rights of Custodian, Disbursement Agent and Buyer under this
Agreement shall inure to the benefit of Custodian, Disbursement Agent and Buyer
and their successors and permitted assigns, and all obligations of Seller and
each Seller Entity shall bind its respective successors and assigns.

            Section 22. Entire Agreement; Severability.

            This Agreement, the Edit Check Agreement and the Repurchase
Agreement contain the entire agreement with respect to the rights and
obligations of Custodian and Disbursement Agent relating to the Purchased Assets
among Custodian, Disbursement Agent, Buyer and Seller. If any of the provisions
of this Agreement shall be held invalid or unenforceable, this Agreement shall
be construed as if not containing such provisions, and the rights and
obligations of the parties hereto shall be construed and enforced accordingly.

            Section 23. Execution in Counterparts.

            This Agreement may be executed in counterparts, each of which when
so executed shall be deemed to be an original and all of which when taken
together shall constitute one and the same agreement.

            Section 24. Tax Reports.

            Custodian shall not be responsible for the preparation or filing of
any reports or returns relating to federal, state or local income taxes with
respect to this Agreement, other than in respect of Custodian's compensation or
for reimbursement of expenses.

            Section 25. Assignment by Buyer.

            Buyer hereby notifies Custodian that Buyer may assign, as of the
applicable Purchase Date, all of its right, title and interest in and to some or
all of the Purchased Assets to a third party assignee (an "Assignee"), subject
only to an obligation on the part of the Assignee to release its interest in
each such Purchased Asset to Buyer to permit Custodian, Buyer or its designee to
make delivery thereof in accordance with the terms of this Agreement. Seller
hereby irrevocably consents to any such assignment. Subject to any limitations
in any agreement between the Assignee and Buyer, the Assignee may, upon notice
of Buyer's default, directly enforce and exercise such rights under this
Agreement that have been assigned or pledged to it and, until otherwise notified
by the Assignee, Buyer shall no longer have any of such rights. Custodian shall
assume that any assignment from Buyer to the Assignee is subject to no
limitations that are not expressly set forth in this Agreement.

            Section 26. Submission to Jurisdiction; Waivers.

            EACH OF BUYER, EACH SELLER ENTITY, CUSTODIAN AND DISBURSEMENT AGENT
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 RESPECT THEREOF, TO THE EXCLUSIVE
GENERAL JURISDICTION OF THE COURTS OF THE STATE OF NEW YORK SITTING IN THE
BOROUGH OF MANHATTAN, 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 BE EFFECTED BY MAILING A COPY THEREOF BY REGISTERED OR CERTIFIED MAIL (OR
ANY SUBSTANTIALLY SIMILAR FORM OF MAIL), POSTAGE PREPAID, TO ITS ADDRESS SET
FORTH UNDER ITS SIGNATURE BELOW OR AT SUCH OTHER ADDRESS OF WHICH EACH OTHER
PARTY HERETO SHALL HAVE BEEN NOTIFIED;

            (d) AGREES THAT NOTHING HEREIN SHALL AFFECT THE RIGHT TO EFFECT
SERVICE OF PROCESS IN ANY OTHER MANNER PERMITTED BY LAW OR SHALL LIMIT THE RIGHT
TO SUE IN ANY OTHER JURISDICTION; AND

                                      -37-

            (e) WAIVES, TO THE FULLEST EXTENT PERMITTED BY APPLICABLE LAW, ANY
AND ALL RIGHT TO TRIAL BY JURY IN ANY LEGAL PROCEEDING ARISING OUT OF OR
RELATING TO THIS AGREEMENT, ANY OTHER REPURCHASE DOCUMENT OR THE TRANSACTIONS

            Section 27. Confidentiality.

            Each of Custodian and Disbursement Agent hereby acknowledges and
agrees that (i) all written or computer-readable information provided by Buyer
or Seller regarding Buyer or Seller and (ii) the terms of this Agreement and the
Repurchase Agreement (the "Confidential Information"), shall be kept
confidential and shall not be divulged to any Person other than the parties
hereto without Buyer's and Seller's prior written consent except to the extent
that (i) Custodian or Disbursement Agent reasonably deems necessary to do so in
working with legal counsel, auditors, taxing authorities or other governmental
agencies or regulatory bodies or in order to comply with any applicable federal
or state laws, (ii) any portion of the Confidential Information is in the public
domain other than due to a breach of this covenant by the Custodian or the
Disbursement Agent, as the case may be, or by the disclosing party or (iii) to
the extent that Custodian or Disbursement Agent, as applicable, is required to
disclose Confidential Information pursuant to the requirements of any legal
proceeding, Custodian or Disbursement Agent, as applicable, shall notify Buyer
and Seller within one Business Day of its knowledge of such legally required
disclosure so that Buyer or Seller may seek an appropriate protective order
and/or waive Custodian's or Disbursement Agent's compliance, as applicable, with
this Agreement. Notice shall be both by telephone and in writing. In the absence
of a protective order or waiver, Custodian or Disbursement Agent, as applicable,
may disclose the relevant Confidential Information if, in the written opinion of
its counsel, failure to disclose such Confidential Information would subject
Custodian or Disbursement Agent, as applicable, to liability for contempt,
censure or other legal penalty or liability.

            Section 28. Obligations Joint and Several.

            Each of the Seller Entities hereby acknowledges and agrees that it
shall be jointly and severally liable to Buyer, Custodian and Disbursement
Agent, as applicable, for all representations, warranties, covenants,
obligations and indemnities of Seller hereunder.
