            the Underwriting Guidelines;

      (10)  none of the following shall have occurred and/or be continuing:

                        (A) an event or events shall have occurred in the good
                  faith determination of Buyer resulting in the effective
                  absence of a "repo market" or comparable "lending market" for
                  financing debt obligations secured by mortgage loans or
                  securities or an event or events shall have occurred resulting
                  in Buyer not being able to finance Purchased Assets through
                  the "repo market" or "lending market" with traditional
                  counterparties at rates which would have been reasonable prior
                  to the occurrence of such event or events; or

                        (B) an event or events shall have occurred resulting in
                  the effective absence of a "securities market" for securities
                  backed by mortgage loans or an event or events shall have
                  occurred resulting in Buyer not being able to sell securities
                  backed by mortgage loans at prices which would have been
                  reasonable prior to such event or events; or

                        (C) there shall have occurred a material adverse change
                  in the financial condition of Buyer which affects (or can
                  reasonably be expected to affect) materially and adversely the
                  ability of Buyer to fund its obligations under this Agreement;

      (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
            an Asset Schedule and Exception Report, dated the Purchase Date,
            duly completed and with exceptions acceptable to Buyer in its sole
            discretion in respect of Eligible Assets to be purchased hereunder
            on such Business Day;

      (12)  Buyer shall have received from Seller a Warehouse Lender's Release
            Letter substantially in the form attached to the Custodial and
            Disbursement Agreement (or such other form acceptable to Buyer) or a
            Seller's Release Letter substantially in the form attached to the
            Custodial and Disbursement Agreement (or such other form acceptable
            to Buyer) covering each Eligible Asset to be sold to Buyer;

      (13)  prior to the purchase of any Mortgage Loan acquired (by purchase or
            otherwise) by Seller from any third party, including without
            limitation, any Affiliate of Seller, Buyer shall have received a
            True Sale Certification;

      (14)  Buyer shall not have determined that the introduction of, or a
            change in, any Requirement of Law or in the interpretation or
            administration of any Requirement of Law applicable to Buyer has
            made it unlawful, and no Governmental Authority shall have asserted
            that it is unlawful, for Buyer to enter into Transactions;

      (15)  the Repurchase Date for such Transaction is not later than the
            Termination Date;

      (16)  after giving effect to the requested Committed Transaction, the
            aggregate amount of outstanding Committed Transactions shall not
            have Purchase Prices in excess of the Maximum Committed Amount;

      (17)  after giving effect to the requested Uncommitted Transaction, the

      (18)  to the extent there are any MERS Designated Mortgage Loans, Buyer
            shall have received from Seller a copy of a fully executed
            Electronic Tracking Agreement;

      (19)  Buyer shall have received from Seller, with respect to MERS
            Designated Mortgage Loans, a MERS Report reflecting Seller as
            Investor and no Person named in the Interim Funder field for each
            such MERS Designated Mortgage Loan;

      (20)  immediately prior to the requested Transaction and also after giving
            effect thereto and to the intended use of the proceeds thereof, the
            Tangible Net Worth of AHMIC and its consolidated Subsidiaries shall
            be at least $500,000,000; provided, however, that in no event shall
            the Seller's failure to meet such Tangible Net Worth test result in
            any Non-Use Fee or Termination Fee to the Seller hereunder;

      (21)  immediately prior to the requested Transaction and also after giving
            effect thereto and to the intended use of the proceeds thereof,
            Seller shall not permit, for any period of three (3) consecutive
            calendar months, Net Income of AHMIC and its consolidated
            Subsidiaries for such period determined on a monthly basis, before
            income taxes for such period and distributions made during such
            period, to be less than $1.00; and

      (22)  immediately prior to the requested Transaction and also after giving
            effect thereto and to the intended use of the proceeds thereof,

            Net Worth of AHMIC and its consolidated Subsidiaries at any time to
            be greater than 18:1.

      With respect to any failure of condition precedent to any Transaction
      resulting from the failure of Buyer to approve any replacement facility to
      the Existing Facilities, in no event shall such failure result in any
      Non-Use Fee or Termination Fee to the Seller hereunder.

      Each Transaction Request delivered by Seller hereunder shall constitute a
      certification by Seller that all the conditions set forth in this Section
      3(b) have been satisfied (both as of the date of such notice or request
      and as of the date of such purchase) and shall be deemed to be a request
      for a Committed Transaction; provided that after giving effect to the
      requested Committed Transaction, the aggregate amount of outstanding
      Committed Transactions shall not have Purchase Prices in excess of the
      Maximum Committed Amount, in which case such request shall be deemed a
      request for an Uncommitted Transaction.

(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


                                      -27-
<PAGE>

      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 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.


                                      -28-
<PAGE>

(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 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.


                                      -29-
<PAGE>

(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 a non-use fee (the "Non-Use Fee") as set
      forth in the Side Letter.

(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".


                                      -30-
<PAGE>

      (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.

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.


                                      -31-
<PAGE>

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

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


                                      -32-
<PAGE>

(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 in good faith 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, upon Seller's receipt of
            the certificate described in, and in accordance with the terms of,
            Section 6(d) below, such additional 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 in
      good faith deemed by Buyer to


                                      -33-
<PAGE>

      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, subject to clause (d), 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 6, it shall promptly notify Seller in writing 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) containing the
      calculation thereof and explanation therefor in reasonable detail,
      submitted by Buyer to Seller shall be conclusive in the absence of
      manifest error. Should any event take place that subjects Buyer to any
      payments, expenses or other obligations described in this Section 6,
      Seller shall have the right in its sole discretion to terminate this
      Agreement upon 30 days' notice to Buyer, and termination of this Agreement
      by Seller under such circumstances shall in no event result in any
      Non-Use-Fee or Termination Fee to Seller hereunder.

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

      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

      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 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

      Check Disbursement Account, all "general intangibles", "accounts",
      "chattel paper", "deposit accounts" and "investment property" as defined

      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 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


                                      -35-
<PAGE>

      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.

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:


                                      -36-
<PAGE>

(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 American Home Mortgage Servicing, Inc., 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 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


                                      -37-
<PAGE>

      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 4 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, 2004, 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, 2005 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, 2005, 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 $2,000,000, or (iii) individually or in the aggregate, if
      adversely determined, could reasonably be likely to have a Material
      Adverse Effect.

(i)   No Breach. Neither (a) the execution and delivery of the Repurchase
      Documents nor (b) the consummation of the transactions therein
      contemplated to be entered into by Seller, in compliance with the terms
      and provisions thereof, will conflict with or result in a breach of the
      organizational documents of 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 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.


                                      -38-
<PAGE>

(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


                                      -39-
<PAGE>

            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 on Schedule 5 hereto as may be amended from time to time 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 each Seller Entity's Other Financial Covenants. Seller
      shall give Buyer prior notification if any amendment to any Other
      Financial Covenant in any Existing Financing Facility increases the
      obligations or requirements of Seller thereunder, and such changed Other
      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. AHMS 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 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.

      9-203(d) of the UCC by a Security Agreement previously entered into by
      another Person.

            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

            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;

            Plan or Multiemployer Plan has occurred or exists, a statement
            signed by a senior financial officer of AHMIC setting forth details

                  412(m) of the Code or Section 302(e) of ERISA or any successor
                  provision thereof, shall be a reportable event regardless of

                  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

                  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.

      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).

      notice to Buyer under this Section 11(b).

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

      (2)   comply with the requirements of all applicable laws, rules,
            regulations and orders of Governmental Authorities (including,

            individually or in the aggregate) to have a Material Adverse Effect;

      (3)   keep adequate records and books of account, in which complete
            entries will be made in accordance with GAAP consistently applied;

            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;

            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.

      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

            Material Adverse Effect; and

      (6)   promptly upon the occurrence of any default or event of default
            under the Existing Financing Facilities.

      Each notice pursuant to this Section shall be accompanied by a statement
      of a Responsible Officer of Seller setting forth details of the occurrence
      referred to therein and stating what action Seller has taken or proposes
      to take with respect thereto.

      quarter, Seller shall provide Buyer with a quarterly report, which report

      Underwriting Guidelines. Seller shall not make any material change in the
      Underwriting Guidelines without the prior written consent of Buyer and
      shall review the Underwriting Guidelines periodically to confirm that they
      are being complied with in all material respects and are adequate to meet
      Seller's business objectives. In the event Seller makes any amendment or
      modification to the Underwriting Guidelines, Seller shall promptly deliver
      to Buyer a complete copy of the amended or modified Underwriting
      Guidelines.

(i)   Transactions with Affiliates. No Seller Entity shall enter into any
      transaction with any Affiliate, including without limitation, any
      purchase, sale, lease or exchange of property or the rendering of any
      service unless such transaction is not otherwise expressly prohibited
      under this Agreement and is upon fair and reasonable terms no less
      favorable to such Seller Entity than it would obtain in a comparable arm's
      length transaction with a Person which is not an Affiliate except for (i)
      the acquisition of equity or stock or warrants of an Affiliate, (ii) the
      payment of dividends, in the ordinary course of business, (iii) the
      contribution of capital (not to exceed $5,000,000) to an entity in which
      any Seller Entity holds at least a majority equity interest unless such
      other entity is also a Seller Entity, (iv) the purchase or sale of loans
      in the ordinary course of business which is a true sale and does not
      constitute a fraudulent conveyance and (v) any transaction or series of
      transactions between two or more Seller Entities. No Seller Entity shall
      make a payment that is not otherwise permitted by this Section 11(i) to
      any Affiliate. In no event shall any Seller Entity transfer to Buyer
      hereunder any Mortgage Loan acquired by such Seller Entity from an
      Affiliate of such Seller Entity unless a True Sale Certification has been
      delivered to Buyer prior to such sale or such Affiliate is a Seller
      Entity.

(j)   Limitation on Liens. Immediately upon notice of a Lien or any circumstance
      which could give rise to a Lien on the Purchased Items, Seller will defend
      the Purchased Items

      Lien, security interest or claim on or to the Purchased Items (other than
      any security interest created under this Agreement), and Seller will
      defend the right, title and interest of Buyer in and to any of the
      Purchased Items against the claims and demands of all persons whomsoever.

(k)   Limitation on Distributions. After the occurrence and during the
      continuation of any Default, no Seller Entity shall make any payment on
      account of, or set apart assets for, a sinking or other analogous fund for
      the purchase, redemption, defeasance, retirement or other acquisition of
      any equity or partnership interest of Seller, whether now or hereafter
      outstanding, or make any other distribution in respect thereof, either
      directly or indirectly, whether in cash or property or in obligations of
      Seller, except, with respect to AHMIC and AHMA, any distributions in cash
      or other property to the extent required to satisfy the REIT Distribution
      Requirement; provided, for the avoidance of doubt, that after the
      occurrence and during the continuation of any Default, no Seller Entity
      (other than AHMIC and AHMA) shall make any distributions as set forth in
      this Section 11(k).

      and distributions made during such Test Period, to be less than $1.00.

(m)   Maintenance of Tangible Net Worth; Liquidity. Seller shall not permit
      Tangible Net Worth of AHMIC and its consolidated Subsidiaries at any time

      collateral under each Existing Financing Facility.

(n)   Aggregate Collateral Value to the Adjusted Consolidated Funded Debt.
      Seller shall not permit the ratio of the Aggregate Collateral Value to the
      Adjusted Consolidated Funded Debt of AHMIC to be less than 1.00 to 1.00 at
      any time.

      month (the "Reporting Date") containing the following information, on a

                  number of days during the period from and including the date
                  of the exercise or deemed exercise of such option to but
                  excluding the date of payment of the Repurchase Price, (x) the
                  Post-Default Rate to (y) the Repurchase Price for such
                  Transaction as of the Repurchase Date (decreased as of any day
                  by (i) any amounts actually in the possession of Buyer
                  pursuant to clause (C) of this subsection, (ii) any proceeds
                  from the sale of Purchased Assets applied to the Repurchase
                  Price pursuant to subsection (a)(4) of this Section 13, and
                  (iii) any amounts applied to the Repurchase Price pursuant to
                  subsection (a)(4) of this Section 13); and

      (3)   Upon the occurrence of one or more Events of Default, Buyer shall
            have the right to obtain physical possession of the Servicing

            Agreement) and all other files of Seller relating to the Purchased
            Assets and all documents relating to the Purchased Assets which are
            then or may thereafter come in to the possession of Seller or any
            third party acting for Seller and Seller shall deliver to Buyer such
            assignments as Buyer shall request and Buyer shall have the right to
            appoint any Person to act as Servicer for the Purchased Assets.
            Buyer shall be entitled to specific performance of all agreements of
            Seller contained in the Repurchase Documents.

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


                                      -52-
<PAGE>

            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.

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

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

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

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

(c)   Buyer may enforce its rights and remedies hereunder without prior judicial
      process or hearing, and Seller hereby expressly waives any defenses Seller
      might otherwise have to require Buyer to enforce its rights by judicial
      process. Seller 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.

      thereunder or arising out of any other agreement, indebtedness 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,

      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

      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.

      recording. Buyer and Seller consent to the admissibility of such tape
      recordings in any court, arbitration, or other proceedings. The parties
      agree that a duly authenticated transcript of such a tape recording with a
      Responsible Officer of such party 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


                                      -55-
<PAGE>

      any other provision or agreement herein and shall be enforceable
      notwithstanding the unenforceability of any such other provision or
      agreement. No amendment, modification or release from any provision of
      this Agreement shall be effective unless in writing and executed by or on
      behalf of the party or parties to be charged therewith and shall be
      effective only in the specific instance and for the specific purpose for
      which given.

19.   NON-ASSIGNABILITY

      The rights and obligations of the parties under this Agreement and under
      any Transaction shall not be assigned by 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 (a) 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) and (b) upon any material adverse
      change in the terms of, or any material reduction in amounts available to
      Seller or its Affiliates, under any of the Existing Financing Facilities
      (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

            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

            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

            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, during normal business hours, 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,


                                      -59-
<PAGE>

      Buyer or its authorized representatives will be permitted during normal
      business hours to 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 in good faith 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


                                      -60-

            mortgage insurance or with respect to any other Purchased Items

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

            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

            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
            therewith, to give such discharges or releases as Buyer may deem
            appropriate; and (G) generally, to sell, transfer, pledge and make
            any agreement with respect to or otherwise deal with any Purchased
            Items as fully and completely as though Buyer were the absolute
            owner thereof for all purposes, and to do, at Buyer's option and
            Seller's expense, at any time, and from time to time, all acts and
            things which Buyer deems necessary to protect, preserve or realize
            upon the Purchased Items and Buyer's Liens thereon and to effect the
            intent of this Agreement, all as fully and effectively as such
            Seller might do;

      Seller hereby ratifies all that said attorneys shall lawfully do or cause
      to be done by virtue hereof. This power of attorney is a power coupled
      with an interest and shall be irrevocable.

(b)   The powers conferred on Buyer hereunder are solely to protect Buyer's
      interests in the Purchased Items and Purchase Assets and shall not impose
      any duty upon it to exercise any such powers. Buyer shall be accountable
      only for amounts that it actually receives as a result of the exercise of
      such powers, and neither it nor any of its officers, directors, employees
      or agents shall be responsible to Seller for any act or failure to act
      hereunder, except for its or their own gross negligence or willful
      misconduct.

30.   CONFLICTS

      In the event of any conflict between the terms of this Agreement, any
      other Repurchase Document and any Confirmation, the documents shall
      control in the following order of priority: first, the terms of the
      Confirmation shall prevail, then terms of this Agreement shall prevail,
      and then terms of the other Repurchase Documents shall prevail.

31.   SET-OFF

      In addition to any rights and remedies of Buyer provided by this Agreement
      and by law, Buyer shall have the right, without prior notice to Seller,
      any such notice being expressly waived by Seller to the extent permitted
      by applicable law, upon any amount becoming due and payable by Seller to
      Buyer hereunder or otherwise (whether at the stated maturity, by
      acceleration or otherwise) to set-off and appropriate and apply against
      such amount any and all monies and other property of Seller, any and all
      deposits (general or special, time or demand, provisional or final), in
      any currency, and any and all other credits, indebtedness or claims, in
      any currency, in each case whether direct or indirect, absolute or
      contingent, matured or unmatured, and in each case at any time held or
      owing by Buyer or any Affiliate thereof to or for the credit or the
      account of Seller. Buyer agrees promptly to notify Seller after any such
      set-off and application made by Buyer; provided that the failure to give
      such notice shall not affect the validity of such set-off and application.

32.   OBLIGATIONS JOINT AND SEVERAL

(a)   Each of the Seller Entities hereby acknowledges and agrees that it shall
      be jointly and severally liable to Buyer for all representations,
      warranties, covenants, obligations and indemnities of Seller hereunder.

(b)   Each of the Seller Entities waives any and all notice of the creation,
      renewal, extension or accrual of any of the Repurchase Obligations and
      notice of or proof of reliance by the Buyer upon the obligations of such
      Seller Entity set forth herein or acceptance of such obligations by such
      Seller Entity hereunder. Each Seller Entity waives diligence, presentment,
      protest, demand for payment and notice of default or nonpayment to or upon
      each other Seller Entity with respect to the Repurchase Obligations. Each
      Seller Entity's obligations shall be construed as continuing, absolute and
      unconditional obligations without regard to (i) any defense, set-off or
      counterclaim (other than a defense of payment or performance) which may at
      any time be available to or be asserted by any Seller Entity against the
      Buyer, or (ii) any other circumstance whatsoever (with or without notice
      to or knowledge of any Seller Entity) which constitutes, or might be
      construed to constitute, an equitable or legal discharge of such Seller
      Entity for the Repurchase Obligations. Each Seller Entity hereby waives
      any defense arising by reason


                                      -63-
<PAGE>

      of, and any and all right to assert against the Buyer any claim or defense
      based upon, an election of remedies by the Buyer which in any manner
      impairs, affects, reduces, releases, destroys and/or extinguishes such
      Seller Entity's subrogation rights, rights to proceed against such Seller
      Entity or any other party for reimbursement or contribution, and/or any
      other rights of such Seller Entity to proceed against any other Seller
      Entity, against any other guarantor, or against any other person or
      security.

(c)   The parties intend that the each Seller Entity's Repurchase Obligations
      are primary obligations and not in the nature of a guaranty or suretyship.

                            [SIGNATURE PAGE FOLLOWS]
