CUSTODIAL AGREEMENT (the “Agreement”), among AMERICAN HOME MORTGAGE CORP., a New York corporation, as a Seller (hereinafter, together with its successors and assigns, “AHMC”), AMERICAN HOME MORTGAGE SERVICING, INC., a Maryland corporation, as a Seller and as the Servicer (hereinafter, together with its successors and assigns, “AHMS”), AMERICAN HOME MORTGAGE ACCEPTANCE, INC., a Maryland corporation, as a Seller (hereinafter, together with its successors and assigns, “AHMA”), AMERICAN HOME MORTGAGE INVESTMENT CORP., a Maryland corporation, as a Seller (hereinafter, together with its successors and assigns, “AHMIC” and together with AHMC, AHMS and AHMA, collectively, the “Sellers”), CALYON NEW YORK BRANCH (“Calyon”), in its capacity as the administrative agent for the “Purchasers” under and as defined in the Repurchase Agreement referred to below (the “Administrative Agent”), and DEUTSCHE BANK NATIONAL TRUST COMPANY, in its capacity as custodian hereunder (the “Custodian”).

WHEREAS, the Sellers have entered into a Repurchase Agreement dated as of November 21, 2006 (as the same may be amended, restated, supplemented or modified from time to time, the “Repurchase Agreement”), among the Sellers, the Issuers, Calyon, as the Administrative Agent, the Banks, and American Home Mortgage Servicing, Inc. (the “Servicer”), in its capacity as servicer thereunder, pursuant to which the Purchasers may make Purchases on a revolving basis;

WHEREAS, the parties now desire to enter into this Custodial Agreement (the “Agreement”) to provide for the holding and monitoring of Mortgage Assets to be sold, subject to repurchase, pursuant to the Repurchase Agreement;

NOW, THEREFORE, the parties agree as follows:

ARTICLE I

GENERAL TERMS

1.1. Certain Definitions.

Unless otherwise defined herein or in the Repurchase Agreement, terms are used herein as defined in Exhibit D-1 hereto.

ARTICLE II

APPOINTMENT OF CUSTODIAN

2.1. Appointment.

(a) The Administrative Agent, on behalf of the Purchasers, hereby appoints Deutsche Bank National Trust Company, as “Custodian” under this Agreement and authorizes the Custodian to take such action on the Administrative Agent’s behalf and to

exercise such powers and perform such duties as are hereby expressly delegated to the Custodian by the terms of this Agreement, together with such powers as are reasonably incidental thereto.

(b) The Custodian hereby accepts such appointment and agrees to hold, maintain, and administer for the exclusive benefit of the Purchasers all Mortgage Assets at any time delivered to it by or on behalf of the Sellers as herein provided. The Custodian acknowledges and agrees that it is acting and will act with respect to the Mortgage Assets for the exclusive benefit of the Purchasers and shall not be subject with respect to the Mortgage Assets in any manner or to any extent to the direction or control of the Sellers except as expressly permitted hereunder. The Custodian (or its designee) for the benefit of the Administrative Agent and the Purchasers, agrees to act in accordance with this Agreement and in accordance with any written instructions of the Administrative Agent as provided in this Agreement. Under no circumstances shall the Custodian deliver possession of the Mortgage Assets to the Sellers except in accordance with the express terms of this Agreement or otherwise upon the written instruction of the Administrative Agent as provided in this Agreement. Upon a written request by the Servicer (who shall not request substitution of Eligible Mortgage Loans if, as reflected in the most recent Purchase Report, the Recognized Value of Purchased Mortgage Assets which are Eligible Mortgage Assets, immediately after giving effect to a requested transfer and any accompanying substitution of Mortgage Loan Collateral, is less than the total Invested Amount) and approval by the Sellers, Custodian is authorized to permit substitution of Eligible Mortgage Loans (as certified by the Servicer to be Eligible Mortgage Loans) unless the Custodian shall have received written notice from the Administrative Agent that a Default or Event of Default has occurred.

2.2. Custodial Fees.

The Servicer agrees to pay such fees and expenses of the Custodian as shall be agreed to in writing between the Custodian and Servicer. The obligation of the Servicer to pay the Custodian’s fees and expenses for its services under this Agreement shall survive the termination of this Agreement and the earlier resignation or removal of the Custodian.

ARTICLE III

(c) a Disbursement Account Control Agreement in favor of the Administrative Agent for the benefit of the Purchasers substantially in the form of Exhibit D-13 hereto; and

(d) the Assignments provided for in Section 3.2 hereof in the form of Exhibit D-4 hereto.

3.2. Delivery of Mortgage Assets to the Custodian.

(a) Periodically, the Sellers may deliver Mortgage Loan Collateral to the Custodian to hold as bailee for the Purchasers. The Sellers may deliver from time to time such other documents as shall be specified in a notice by the Administrative Agent to the Custodian as documents that are required to be delivered to the Custodian pursuant to this Agreement in order to meet requirements of the Repurchase Agreement or agreements required by the Repurchase Agreement. Each delivery shall be made in association with an assignment (the “Assignment”) to the Purchasers in all Mortgage Loans, Take-Out Commitments, Hedges and related Mortgage Assets delivered with or described in such Assignment or any schedules thereto. The Sellers shall use substantially the form illustrated in Exhibit D-4 hereto for each Assignment, or such other form as may be acceptable to, or required by, the Administrative Agent, from time to time.

(b) Each Assignment delivered to the Custodian shall be accompanied by a completed Schedule II and Schedule III, using the forms of such schedules as prescribed in Exhibit D-4 hereto, together with a current Purchase Report, and with respect to each Mortgage Loan described in Schedule II to each Assignment the following items (collectively, the “Principal Mortgage Documents”):

(i) the original of each Mortgage Note, endorsed by the Servicer in blank (without recourse) and all intervening endorsements thereto;

(ii) an original executed assignment in blank for each Mortgage securing such Mortgage Loan, in recordable form, executed by the Seller, in the case of each Mortgage Loan that is not a MERS Designated Mortgage Loan; and

(iii) a certified copy of the executed Mortgage related to such Mortgage Note, certified by the Servicer, escrow agent, title company, closing attorney or an Affiliate of the Servicer as a true and correct copy.

(c) The Servicer shall hold in trust for the Administrative Agent for the benefit of the Purchasers, with respect to each Mortgage Loan included in the Mortgage Assets (the following being referred to, collectively, as the “Other Mortgage Documents”):

(i) the original filed Mortgage relating to such Mortgage Loan; provided, however, that until an original Mortgage is received from the public official charged with its filing and recordation, a copy, certified by the closing agent to be a true and correct copy of the filed and recorded original, may be used by the Sellers to satisfy this requirement;

(ii) other than with respect to a HUD Repossessed Property that is sold to a consumer, a mortgagee’s policy of title insurance (or binding unexpired commitment to issue such insurance if the policy has not yet been delivered to the Servicer) insuring that the original mortgagee and its successors and assigns have a perfected, first-priority Lien created by the Mortgage securing such Mortgage Loan (subject to title exceptions that conform to the related Take-Out Commitment) in a policy amount not less than the principal amount of such Mortgage Loan;

(iii) the original hazard insurance policy, appropriately indicating that all insurance proceeds will be paid to the original mortgagee and its successors and assigns, referred to in Section 6.6(b) of the Repurchase Agreement which relate to such Mortgage Loan, or other evidence of insurance acceptable to the Administrative Agent;

(iv) the form of current appraisal of the Property described in the Mortgage, prepared by a state licensed appraiser, that complies with all applicable Governmental Requirements, provided, however, that no appraisal shall be required for Mortgage Loans (x) financing HUD repossessed Property that is sold to a consumer, financed with an FHA loan, fully insurable and in accordance with FHA guidelines, but for which an appraisal is not required, or (y) representing so called VA Rate Reduction or FHA streamline refinances, insurable in accordance with VA and FHA guidelines, but for which an appraisal is not required; and

(v) all other original documents.

Upon three Business Days’ prior written notice by the Administrative Agent to the Custodian, the Custodian will receive from the Servicer all such items, held in trust. The Custodian shall hold such items as bailee for the Administrative Agent or such other party as may be designated in such notice.

(d) The Servicer shall provide the Custodian and the Administrative Agent with full access to all Other Mortgage Documents held in trust for the Administrative Agent at all times.

(e) With respect to each Assignment, together with the related electronic transmission, that is received by the Custodian by 11:30 a.m. (eastern time) on a Business Day, the Custodian shall include the Mortgage Loans identified thereon on the Custodian Daily Report to be delivered electronically on the following Business Day, even if the Custodian has not completed its review of the related Principal Mortgage Documents. The Custodian shall prepare by 10:30 a.m. (eastern time) on such following Business Day, the Custodian Daily Report provided for in Section 3.8 hereof, and furnish it electronically to the Administrative Agent, the Managing Agents and the Sellers. The Custodian shall review the Principal Mortgage Documents for up to 500 Mortgage Loans delivered with any such Assignment no later than the opening of business of the Custodian on the Business Day following delivery of such Custodian Daily Report. The Custodian shall have one (1) additional Business Day to review each additional set of 500 Mortgage Loans in excess of the initial set of 500 Mortgage Loans; provided, that, if the Custodian does not complete its review of any such

Principal Mortgage Documents within one (1) Business Day after receiving such Principal Mortgage Documents and including the related Mortgage Loan on a Custodian Daily Report, the Custodian shall report the Recognized Value for any and all such Mortgage Loans as zero on the Custodian Daily Report for the next Business Day. The Custodian’s responsibility to review such Mortgage Assets is limited to the review steps described on Schedule I hereto.

(f) The Custodian shall, acting on behalf of the Purchasers, and as agent and bailee of, and as custodian for, the Purchasers, retain possession and custody of the documents delivered to the Custodian pursuant hereto, which documents shall, subject to Sections 4.2(k) and 4.4, remain in the state of California for all purposes until the Mortgage Assets are to be released pursuant to Section 3.4 hereof.

(g) Notwithstanding the foregoing provisions of Section 3.2, the Servicer on behalf of Sellers may ship Other Mortgage Documents to Approved Take-Out Investors under bailment for review by the Approved Take-Out Investor prior to purchase of a Mortgage Note under a Take-Out Commitment.

(h) The Servicer shall deliver to the Custodian within the first five (5) Business Day of each calendar month a report (the “Monthly Payment Status Report”), on a form mutually acceptable to the Servicer and the Custodian, describing the delinquency status of each Mortgage Loan as of the last day of the preceding calendar month.

3.3. Power of Attorney.

(a) Subject to subsection (b) below, the Sellers hereby irrevocably appoint the Administrative Agent, for the benefit of the Purchasers, its attorney in fact, with full power of substitution, for and on behalf and in the name of the Sellers, to: (i) endorse and deliver to any Person any check, instrument or other paper coming into the Custodian’s, the Administrative Agent’s or any Purchaser’s possession and representing payment made in respect of any Mortgage Note or Take-Out Commitment Document delivered hereunder or in respect of any other Mortgage Assets; (ii) prepare, complete, execute, deliver and record any Assignment to be delivered to the Custodian, the Administrative Agent or to any other Person of any Mortgage relating to any Mortgage Note delivered hereunder as Mortgage Loan Collateral; (iii) endorse and deliver any Mortgage Note as Mortgage Loan Collateral arising as proceeds thereof, and do every other thing necessary or desirable to effect transfer of all or any part of the Mortgage Loan Collateral to the Administrative Agent, for the benefit of the Purchasers, or to any other Person; (iv) take all necessary and appropriate action with respect to all Repurchase Obligations and the Mortgage Loan Collateral to be delivered to the Custodian or the Administrative Agent or held by the Sellers in trust for the Administrative Agent for the benefit of the Purchasers; (v) commence, prosecute, settle, discontinue, defend, or otherwise dispose of any claim relating to any Take-Out Commitment or any other part of the Mortgage Loan Collateral; and (vi) sign the related Seller’s name wherever appropriate to effect the performance of this Agreement.

(b) This Section 3.3 shall be liberally, not restrictively, construed so as to give the greatest latitude to the Administrative Agent’s powers, as the Sellers’ attorney-in-fact, to collect, sell, and deliver any of the Mortgage Loan Collateral and all other documents relating thereto. The powers and authorities herein conferred on the Administrative Agent may be exercised by the

Administrative Agent through any Person who, at the time of the execution of a particular instrument, is an authorized officer or agent of the Administrative Agent. The power of attorney conferred by this Section 3.3 shall become effective upon the occurrence, and remain effective during the continuance, of a Default or an Event of Default and is granted for a valuable consideration and is coupled with an interest and irrevocable so long as the Repurchase Obligations, or any part thereof, shall remain unpaid or any Bank Commitment is outstanding. All Persons dealing with the Administrative Agent, any officer thereof, or any substitute attorney, acting pursuant hereto shall be fully protected in treating the powers and authorities conferred by this Section 3.3 as existing and continuing in full force and effect until advised by the Administrative Agent that the Repurchase Obligations have been fully and finally paid and satisfied and all Bank Commitments have been terminated.

3.4. Transfer and Shipping of Mortgage Assets.

(a) Generally. Subject to the limitations contained in this Section 3.4, in connection with a sale or other transfer contemplated by clause (a) or (b), and so long as no Default or Event of Default is continuing, the Sellers or the Servicer (on behalf of the Sellers) may request transfers of the Administrative Agent’s interest in all or any part of the Mortgage Assets (including transfers from the Collection Account and release of funds owned by the Sellers and held in the Collection Account) at any time, and from time to time; provided that no such request shall be granted unless, in addition to the satisfaction of the other conditions contained in this Section 3.4,

(i)(immediately after giving effect to any requested transfer) the total Recognized Value of all Purchased Mortgage Assets that are Eligible Mortgage Assets shall equal or exceed the Invested Amount, or

(ii)(A) the Sellers pay a Repurchase Price in an amount, or (B) the Sellers deliver to the Custodian as bailee for the Administrative Agent substitute Eligible Mortgage Assets with a Recognized Value, such that after giving effect to such payment or delivery, the total Recognized Value of all Purchased Mortgage Assets that are Eligible Mortgage Assets will equal or exceed the Invested Amount (the satisfaction of such conditions, a “Margin Sufficiency”). Each request for a partial transfer of Mortgage Assets from the Collection Account shall be addressed to the Custodian and the Administrative Agent and shall be substantially in the form of Exhibit D-11 attached hereto (a “Collection Account Release Notice”).

So long as no Default or Event of Default is continuing, and there is a Margin Sufficiency, the Purchasers will be deemed to consent if the Servicer (on behalf of the Sellers) transfers funds from the Collection Account to the Disbursement Account; provided, that the Servicer shall not request and the Custodian shall not permit funds to be released from the Disbursement Account unless the total Recognized Value of all Purchased Mortgage Assets which are Eligible Mortgage Assets (immediately after giving effect to the requested release) equals or exceeds the Invested Amount, as shown on the most recent Purchase Report. Each request for a partial release of Mortgage Assets (a “Transfer Request”) shall be addressed to the Custodian and shall be substantially in the form provided

as Exhibit D-5 attached hereto (or such other form as may be reasonably acceptable to or required by the Administrative Agent, from time to time).

(b) Shipping Pursuant to Sale. So long as no Default or Event of Default is continuing and there is a Margin Sufficiency, the Sellers or the Servicer (on behalf of the Sellers) may (and, while a Default or Event of Default is continuing, upon direction of the Administrative Agent, the Sellers shall) from time to time submit a Shipping Request that would permit the repurchase by the Sellers of Purchased Mortgage Loans from the respective Purchasers and a simultaneous sale of such Mortgage Loans to, or the pooling of Mortgage Loans for, an Approved Take-Out Investor, pursuant to a Take-Out Commitment. Upon the receipt by the Custodian of a Shipping Request from the Sellers identifying Mortgage Assets to be delivered to an Approved Take-Out Investor, and so long as (x) (i) there is a Margin Sufficiency, and (ii) no Default or Event of Default shall be in existence or would be caused thereby or, (y) if a Default or Event of Default is in existence or would be caused thereby, or there is not a Margin Sufficiency, the Administrative Agent has approved the Shipping Request:

(i) The Custodian shall deliver to the Approved Take-Out Investors, or its loan servicing provider or custodian, under the Custodian’s “Bailee and Security Agreement Letter,” substantially in the form of Exhibit D-6(a), or D-6(b) hereto or such other form as may be approved by the Administrative Agent as appropriate, the items of Mortgage Loan Collateral being sold which are held by the Custodian as bailee for the Administrative Agent pursuant to Section 3.2 hereof, with the transfer of the interest of the Administrative Agent on behalf of the Purchasers in such items being conditioned upon timely payment to the Collection Account of the amount described in Section 3.4(b)(iii);

(ii) The Servicer shall, as agent for the Administrative Agent, deliver to such Approved Take-Out Investor, or such Approved Take-Out Investor’s loan servicing provider or custodian, under a letter agreement or other arrangement approved by the Administrative Agent the items held by the Servicer pursuant to Section 3.2(c) that are related to the Mortgage Loan Collateral to be transferred on the condition that such Approved Take-Out Investor or its loan servicing provider or custodian shall hold or control such Other Mortgage Documents as bailee for the Administrative Agent for the benefit of the Purchasers until the Approved Take-Out Investor has paid the full purchase price for such Mortgage Loan Collateral to the Collection Account pursuant to the terms of the related Take-Out Commitment or Hedge;

(iii) Within forty-five (45) days after the delivery by the Custodian to such Approved Take-Out Investor or its loan servicing provider or custodian of the items of Mortgage Loan Collateral described in Section 3.4(b) or (ii), the Sellers shall make a payment, or shall cause a payment to be made, to the Collection Account, for distribution to the Administrative Agent for the account of the Purchasers in an amount at least equal to the Repurchase Price for such Mortgage Loan Assets or shall substitute Eligible Mortgage Assets as permitted by this Section 3.4 it being understood that the Custodian shall have no responsibility to verify the purchase price; and

(iv) With respect to each Shipping Request that is received by the Custodian by 11:30 a.m. (eastern time) on a Business Day, the Custodian shall use due diligence and best efforts to review such Shipping Request and prepare the Mortgage Loan files identified in each Shipping Request, for shipment prior to the close of business on the day the Shipping Request is received by the Custodian, and, in any event shall review such Shipping Request and prepare the Mortgage Loan files identified in such Shipping Request no later than 24 hours after such Shipping Request is received by the Custodian.

(c) Transfers. So long as no Default or Event of Default is continuing of which a Responsible Officer of the Custodian has received written notice, subject to Section 3.4(a) and (b), and there is a Margin Sufficiency, the Purchasers consent to permit the Sellers or Servicer on behalf of the Sellers to cause the Custodian to reflect the transfer of Mortgage Loans to any Permitted Transferees (as defined below) by means of its daily electronic transmissions to the Custodian, together with delivery of a Transfer Request delivered to the Custodian, on or before 11:30 a.m. (eastern time), identifying each Mortgage Loan being transferred. The Custodian’s sole responsibility with respect to any such transfers shall be to correctly reflect such transfers on its computer system and books and records and to indicate, on its Custodian’s Daily Report to be delivered on such Business Day, that such transfers have been effected. “Permitted Transferees” means any of the Sellers, in connection with any sale and transfer thereto effected pursuant to the terms of the Repurchase Agreement and any Approved Take-Out Investor. However, requested transfers will not be made if (A) as reflected in the most recent Purchase Report, the Invested Amount will equal or exceed Recognized Value of Purchased Mortgage Assets which are Eligible Mortgage Assets immediately after giving effect to a requested transfer and any accompanying substitution of Mortgage Assets, or (B) the Custodian shall have received written notice from the Administrative Agent that a Default or Event of Default has occurred.

(d) Continuation of Purchasers’ Interest in Mortgage Loans. Unless released in writing by the Administrative Agent as herein provided, the Purchasers’ interest in all Mortgage Loan Collateral transmitted pursuant to Section 3.4(b) shall continue in effect until such time as the Administrative Agent shall have received payment in full of the amount described in Section 3.4(b)(iii).

(e) Application of Proceeds; No Duty. Neither the Administrative Agent, nor the Custodian, nor any Purchaser shall be under any duty at any time to credit the Sellers for any amounts due from any Approved Take-Out Investor in respect of any purchase of any Mortgage Assets contemplated under Section 3.4(b) above, until the Administrative Agent has actually received such amount in the form of immediately available funds, for deposit to the Collection Account. Neither the Administrative Agent, nor the Custodian, nor any Purchaser shall be under any duty at any time to collect any amounts or otherwise enforce any obligations due from any Approved Take-Out Investor in respect of any such purchase.

(f) Mandatory Redemption of Mortgage Assets. Notwithstanding any provision hereof to the contrary, if at any time a Margin Deficit exists, the Sellers shall, immediately upon receipt of notice (which may be by telephone, promptly confirmed in

writing) from the Administrative Agent or the Custodian, make a deposit to the Collection Account or pledge, assign and deliver additional or substitute Purchased Mortgage Assets which are Eligible Mortgage Assets to the Administrative Agent for the benefit of the Purchasers, so that, immediately after giving effect to such payment or pledge and assignment, the total Recognized Value of Eligible Mortgage Assets shall be equal to or greater than the Invested Amount.

(g) Representation in Connection with Releases, Sales and Transfers. The Sellers and the Servicer each represents and warrants that each request for any release or transfer pursuant to Section 3.4(a), Section 3.4(b) or Section 3.4(c) shall automatically constitute a representation and warranty to the Purchasers, the Administrative Agent, and the Custodian to the effect that immediately before and after giving effect to such release or Transfer Request, the Recognized Value of Purchased Mortgage Assets which are Eligible Mortgage Assets shall equal or exceed the Invested Amount. In connection with any request for a release or a Transfer Request, the Custodian may assume, in the absence of written notice to the contrary received from the Administrative Agent, that immediately before and after giving effect to such release of Mortgage Assets or Transfer Request, no Default or Event of Default exists.

(h) Limitation on Releases. Notwithstanding any provision to the contrary, the Custodian shall not release any Mortgage Assets unless (i) payment of what purports to be the purchase price by the Approved Take-Out Investor has been made in immediately available funds to the Collection Account; or (ii) immediately before and after giving effect thereto, the total Recognized Value of Purchased Mortgage Assets which are Eligible Mortgage Assets (including any Eligible Mortgage Loans substituted for those Eligible Mortgage Loans being released) shall equal or exceed the Invested Amount, as reflected in the most recent Purchase Report.

3.5. Releases of Mortgage Notes for Servicing.

The Servicer may from time to time request, in writing in the form of Exhibit D-7 hereto, that the Custodian deliver a Mortgage Note that constitutes Mortgage Loan Collateral so that (a) such Mortgage Note may be replaced by a corrected Mortgage Note, or (b) any servicing action may take place with respect to such Mortgage Note. Upon receipt by the Custodian of such a request from the Servicer, and so long as the Custodian has not received written notice that a Default or Event of Default shall be in existence, the Custodian shall deliver to the Servicer, under the “Trust Receipt and Security Agreement Letter,” substantially in the form of Exhibit D-7, hereto, or such other form as may be approved by the Administrative Agent, the Mortgage Note to be corrected or serviced, such delivery to be conditioned upon the receipt by the Custodian within fourteen (14) calendar days of either a corrected Mortgage Note, in the case of Mortgage Notes delivered for correction, or the Mortgage Note originally delivered to the Servicer by the Custodian, in the case of a Mortgage Note delivered for a servicing action; provided, that (as certified to the Custodian by the Servicer):

(i) at no time shall Mortgage Notes having an aggregate Recognized Value in excess of 2.5% of the Maximum Facility Amount be so delivered to the Servicer pursuant to this Section 3.5 (the Recognized Value assigned to each such Mortgage Notes delivered for correction shall be determined utilizing as the principal amount of such Mortgage Note the

lesser of the uncorrected face value of such Mortgage Note and the correct face value of such Mortgage Note known to the Sellers or the Servicer; provided, however, that if the correct face value of such Mortgage Note is not known to the Custodian, the Custodian may use the uncorrected face value of such Mortgage Note in determining the Recognized Value);

(ii) with respect to Mortgage Notes delivered for correction, until such time as a corrected Mortgage Note shall have been delivered to the Custodian, the Recognized Value attributed to each Mortgage Note delivered to the Servicer to be corrected in accordance with this Section 3.5 shall be the lesser of the uncorrected face value of such Mortgage Note and the corrected face value of such Mortgage Note known to the Sellers and communicated in writing by the Sellers to the Custodian; provided, however, that if the correct face value of such Mortgage Note is not known to the Custodian, the Custodian may use the uncorrected face value of such Mortgage Note in determining the Recognized Value; and

(iii) notwithstanding the preceding clause (ii), unless, (A) in the case of Mortgage Notes delivered for correction, the corrected Mortgage Note is endorsed in blank (without recourse) and re-delivered to the Custodian within 14 calendar days of the date of delivery by the Custodian of the Mortgage Note to be corrected, or (B) in the case of Mortgage Notes delivered for servicing actions, the original Mortgage Note is re-delivered to the Custodian within 14 calendar days of the date of delivery by the Custodian of the Mortgage Note to be serviced, the Recognized Value attributed to either the Mortgage Note to be delivered and the corrected Mortgage Note, or the Mortgage Note delivered for servicing, shall be zero beginning on the 15^th calendar day; provided, however, that the Recognized Value attributable to the corrected Mortgage Note or the Mortgage Note delivered for correction or servicing will be reinstated promptly upon the subsequent delivery thereof to the Custodian.

3.6. [RESERVED].

3.7. Wet Purchases.

(a) Pursuant to the Repurchase Agreement, the Sellers may from time to time request that certain Purchases be funded after delivery to the Custodian of the related Assignment, but prior to the delivery to the Custodian of the corresponding Principal Mortgage Documents (individually a “Wet Purchase”; collectively “Wet Purchases”). The Sellers and the Administrative Agent acknowledge that Purchases in respect of Wet Purchases are subject to various terms and conditions of the Repurchase Agreement, including those set forth in Section 2.3(c) to the Repurchase Agreement.

(b) Delivery of Principal Mortgage Documents. Within nine (9) Business Days after the date that each Assignment is delivered (and inclusion of the related Wet Loans within the computation of Recognized Value as reported on the Custodian Daily Report) to the Custodian, the Sellers shall deliver to the Custodian all of the Principal Mortgage Documents pertaining to such Wet

Loans, or make a mandatory payment so that after giving effect thereto, the Recognized Value of Eligible Mortgage Assets (excluding such Wet Loans) shall equal or exceed the Invested Amount.

3.8. Mortgage Asset Reporting.

(a) At the commencement of each Business Day, and in no event later than 10:30 a.m. (eastern time), the Custodian shall furnish to the Sellers, Servicer, each Managing Agent and the Administrative Agent electronically a duly completed report in the form of Exhibit D-8 hereto, (the “Custodian Daily Report”) specifying and certifying the then Recognized Value of the Purchased Mortgage Assets which are Eligible Mortgage Assets and other information, all as more fully provided for therein and as set forth on Schedule I hereto, noting, except for any Wet Loans and other Mortgage Loans with respect to which the Custodian has not completed its review of the Principal Mortgage Documents, any applicable Exceptions on Schedule I thereto.

(i) The Custodian may assume the accuracy of all information supplied by the Sellers to the Custodian in any Assignment, or related electronic transmission, received by the Custodian, including but not limited to the acquisition price paid for any Mortgage Loan, the unpaid principal balance of any Mortgage Loan as of its closing and funding date and the weighted average Market Value used in the related Recognized Value calculation and whether the Mortgage Loan is a Conforming Loan, and Alt-A Loan, a Jumbo Loan, a Super Jumbo Loan, a Second-Lien Loan or an Uncovered Mortgage Loan; and

(ii) The Custodian may assume the accuracy of the information supplied by the Sellers to the Custodian, whether written or in any other form acceptable to the Custodian, with respect to a determination as to whether amounts received in the Collection Account represent the Repurchase Price paid for a specific Mortgage Loan and, consequently, whether the Recognized Value of such Mortgage Loan should be removed from such calculation.

(b) Two Business Days prior to the date on which the Maximum Facility Amount has changed, the Servicer shall notify the Custodian and the Sellers (by facsimile) of the new Maximum Facility Amount under the Repurchase Agreement. For purposes of the Custodian Daily Report, the Custodian shall assume that the Maximum Facility Amount is $1,500,000,000 unless it receives written notice to the contrary from the Administrative Agent.

(c) The Custodian shall monitor and report on the Custodian Daily Report the amount of Wet Loans and the portion thereof for which the related Principal Mortgage Documents have been delivered to the Custodian within the time period permitted under Section 3.7.

3.9. Further Obligations of the Custodian.

The Custodian shall promptly notify the Administrative Agent if the Custodian receives written notice (i) that any Lien (other than for the Administrative Agent for the benefit of the Purchasers) has been placed, or attempted to be placed, on any Mortgage

Assets for the Repurchase Obligations or that the Administrative Agent’s interest shall have been challenged or (ii) that any Approved Take-Out Investor has rejected any Mortgage Assets that is related to a Mortgage Loan that has been delivered to the Custodian as Purchased Mortgage Assets for the Repurchase Obligations.

3.10. Segregation of Mortgage Assets.

The Custodian shall keep and maintain the Mortgage Assets on its documents, books and records separate and apart from its other Property and from any Property securing any liabilities of the Sellers to any other Person. Without limitation of the foregoing, the Custodian shall keep and maintain the Mortgage Assets on its documents, books and records separate and apart from any collateral provided by the Sellers in favor of any other lender providing financing to the Sellers. This provision does not require physical separation of the Principal Mortgage Documents or Other Mortgage Documents from collateral held for other loans, but each Mortgage Loan must be maintained in a separate file folder from the documents related to any other mortgage loan.

3.11. Delivery of Required Documents to the Administrative Agent.

Upon written request of the Administrative Agent, after the occurrence of and during the continuation of an Event of Default under the Repurchase Agreement of which a Responsible Officer of the Custodian has received written notice, the Custodian shall deliver within two (2) Business Days (or in contemplation of removing the Custodian as custodian hereunder, the Custodian shall deliver within five (5) Business Days,) to the Administrative Agent or its designee any or all documents and other Mortgage Assets which are then in the possession or control of the Custodian. The Administrative Agent shall provide the Sellers with a copy of any such notice delivered to the Custodian. All special handling and delivery costs shall be paid by the Sellers.

ARTICLE IV

THE CUSTODIAN

4.1. Instructions to the Custodian.

As to any matter not expressly provided for by this Agreement, the Custodian shall not be required to exercise any discretion or take any action, but shall be required to act or to refrain from acting (and shall be fully protected in so acting or refraining from acting) upon the instructions of the Administrative Agent acting on behalf of the Purchasers; provided, however, that the Custodian shall not be required to take any action which may expose the Custodian to any liability that such Custodian determines to be unreasonable in light of the circumstances or that is contrary to this Agreement or any Governmental Requirement.

4.2. Reliance by the Custodian; Responsibility of the Custodian.

(a) The Custodian shall perform its duties hereunder in accordance with the standards followed by the Custodian in dealing with similar property for its own account. Notwithstanding anything to the contrary in this Agreement or any other Transaction Document, neither the Custodian nor any of its respective directors, officers, agents, representatives, employees, attorneys-in-fact or Affiliates shall be liable for any action taken or omitted to be taken by it or them (in their capacity as or on behalf of the Custodian) under or in connection with this Agreement or the other Transaction Documents, except for its or their own gross negligence or willful misconduct, for which the Custodian shall be liable. In no event shall the Custodian, its directors, officers, agents or employees be liable, directly or indirectly, for any special, indirect, punitive or consequential damages.

(b) All Mortgage Assets at any time delivered to the Custodian hereunder shall be held by the Custodian in a fire resistant vault, drawer or other suitable depositary maintained and controlled solely by the Custodian, conspicuously marked to show the interest therein of the Custodian as bailee for the Administrative Agent on behalf of the Purchasers and not commingled with any other assets or property of, or held by, the Custodian for any person other than the Sellers or any of the Sellers. The Custodian shall have responsibility only for documents which have been actually delivered to the Custodian in connection herewith and which have not been released to the Administrative Agent, the Sellers, the Servicer, a transferee or their respective agent or designee in accordance with this Agreement. In the event that a Mortgage Note has been delivered to the Custodian and, subsequently, the Custodian cannot locate such Mortgage Note, then the Custodian shall prepare and execute a lost note affidavit with appropriate indemnification and shall deliver such lost note affidavit to the party that otherwise would have been entitled to delivery of the related Mortgage Note in accordance with this Agreement at the time such Mortgage Note would have been delivered.

(c) Under no circumstances shall the Custodian be obligated to verify the authenticity of any signature on any of the documents received or examined by it in connection with this Agreement or the authority or capacity of any person to execute or issue any such document nor shall the Custodian be responsible for the value, form, substance, validity, perfection (other than by taking and continuing possession of the Mortgage Assets), priority, effectiveness or enforceability of any of such documents nor shall the Custodian be under a duty to inspect, review or examine the documents to determine whether they are appropriate for the represented purpose or that they have been actually recorded or that they are other than what they purport to be on their face.

(d) The Custodian may accept but shall not be responsible for examining, determining the meaning or effect of, or notifying or advising the Sellers or the Administrative Agent in any way concerning, any item or document in any file regarding a Mortgage Loan that is not one of the items or documents listed in Section 3.2(b). The Sellers shall be solely responsible for providing to the Custodian each and every document listed in Section 3.2(b) and for completing or correcting any omission, or incomplete or inconsistent document.

(e) With respect to the calculations in connection with Custodian Daily Reports, the Custodian shall be entitled to rely upon the information contained in any Assignment. The Custodian shall (i) except for Wet Loans for which it has not yet received the Principal Mortgage Documents, hold all Principal Mortgage Documents relating to each Mortgage Loan exclusively for the benefit of the Purchasers under the terms of this Agreement (i.e., is not held by the Custodian for the benefit of any other Person), and (ii) in the case of Wet Loans, monitor and report the amount of such Wet Loans and the portion thereof for which the related Principal Mortgage Documents have been delivered to the Custodian within the time period permitted under Section 3.7. Except as otherwise expressly provided in this Agreement, the Custodian shall have no duty to investigate or conduct any due diligence with respect to such information.

(f) With respect to the determination of whether a Mortgage Loan constitutes an Eligible Mortgage Loan, the Custodian shall be responsible for determining that: (i) such Mortgage Loan meets the requirements of clauses (a)(ii), (d) (with respect to (d), it being understood and agreed that the Custodian is not responsible to determine whether the related Mortgage Note is a legal, valid and binding obligation of the Obligor), (e), (i(iv-vi)), (j) and (m) of the definition of Eligible Mortgage Loan, (ii) that no more than 45 days have lapsed since the date on which the original Mortgage Note evidencing such Mortgage was shipped to the related Approved Take-Out Investor, and (iii) pursuant to Sections 3.9(i), 3.10 and 4.2(e), to the Custodian’s best knowledge such Mortgage Loan is owned by or subject to a perfected first-priority Lien in favor of the Administrative Agent for the benefit of the Purchasers, and, to the Custodian’s best knowledge, is not subject to any other Lien; but the Custodian may assume that all of the other requirements of the definition of Eligible Mortgage Loan have been satisfied.

(g) The Custodian is an agent and bailee only and is not intended to be, nor shall it be construed to be a trustee or fiduciary under this Agreement of or for either or both of the Sellers or the Administrative Agent.

(h) The Custodian shall retain possession and custody of the Principal Mortgage Documents received from the Sellers and pertaining to each Mortgage Loan file as agent and bailee of, and as custodian for, the Administrative Agent for all purposes until the Mortgage Assets are released pursuant to Section 3.4 or 3.5 hereof.

(i) Without limitation of the generality of the foregoing, the Custodian: (i) may consult with legal counsel (including counsel for the Sellers), independent public accountants and other experts selected by the Custodian or the Sellers and shall not be liable for any action taken or omitted to be taken in good faith by it in accordance with the advice of such counsel, accountants or experts; (ii) except as provided in this Agreement, makes no warranty or representation to the Administrative Agent or the holders of any Repurchase Obligations and shall not be responsible to the Administrative Agent or the holders of any Repurchase Obligations for any statements, warranties or representations made in or in connection with this Agreement or the other Transaction Documents; (iii) except as provided in Sections 3.2(e), 3.4(a), (b), (c), (h), 3.8, 3.9 and this Section 4.2, shall not have any duty to ascertain or to inquire as to the performance or observance of any of the terms, covenants or conditions of this Agreement on the part of the Sellers or to inspect the property (including the books and records) of the Sellers; (iv) shall not be responsible to the Administrative Agent or the holders of any Repurchase Obligations for the due execution, legality, validity, enforceability of this Agreement or any other

instrument or document furnished pursuant hereto as it relates to any party other than the Custodian, or for the genuineness, effectiveness, sufficiency, value, perfection or priority of any Mortgage Assets; (v) shall incur no liability under or in respect of this Agreement by acting upon any notice, consent, certificate or other instrument or writing (which may be by telegram, telecopy, cable or telex) believed in good faith by the Custodian, to be genuine and signed or sent by the proper Person; (vi) shall be entitled to rely on the terms of this Agreement and shall be under no obligation to review the terms of the other Transaction Documents, and in the event of any conflict between this Agreement and the Transaction Documents, the terms of this Agreement shall control with respect to the rights and obligations of the Custodian; and (vii) in the event of any amendment, revision, restatement, waiver or other change to the Transaction Documents which could have the effect of increasing the level of effort or changing the scope of work of the Custodian under this Agreement and which was not consented to in writing by the Custodian, shall not be given effect so as to modify in quantity or otherwise the obligations of the Custodian under this Agreement; (as an example only of the foregoing, and to avoid doubt in interpretation of this subsection (vii), an increase in the aggregate commitments under the Purchasers of the Repurchase Agreement shall not, unless the Custodian receives two weeks’ advance written notice of any such amendment, revision, restatement, waiver or other change to the Transaction Documents, require the Custodian to review Mortgage Loan Collateral that would relate to such increased commitment).

(j) The Custodian may execute any of its duties under this Agreement by or through agents, attorneys, custodians, nominees or attorneys-in-fact (which agents, attorneys, custodians, nominees or attorneys-in-fact shall be accorded the same rights and obligations applicable to the Custodian) and shall be entitled to advice of counsel concerning all matters pertaining to such duties. The Custodian shall be responsible for the actions or non-actions of any agent, attorneys, custodians, nominees or attorneys-in-fact selected by it to the extent it would have been liable had it taken such action itself; provided, however, that nothing contained herein shall affect in any manner or any extent the rights of the Sellers or the Administrative Agent against such agents or attorneys-in-fact.

(k) Merger of Custodian. Any entity into which the Custodian may be merged or converted or with which may be consolidated, or any entity resulting from any merger, conversion or consolidation to which the Custodian shall be a party, or any entity succeeding to the business of the Custodian, shall be the successor of the Custodian hereunder, without the execution or filing of any paper or any further act on the part of any of the parties hereto, anything herein to the contrary notwithstanding.

(l) Except as set forth in Section 4.2(a) hereof, none of the provisions of this Agreement shall require the Custodian to expend or risk its own funds or otherwise to incur any liability, financial or otherwise, in the performance of any of its duties hereunder, or in the exercise of any of its rights or powers if it shall have reasonable grounds for believing that repayment of such funds or indemnity satisfaction to it against such risk or liability is not assured to it.

(m) The Custodian may conclusively rely and shall be fully protected in acting or refraining from acting upon any resolution, certificate, statement, instrument, opinion, report, notice, request, consent, order, approval or other paper or document reasonably believed by it to be genuine and to have been signed or presented by the proper party or parties.

4.3. Agents and Affiliates.

The Custodian and its respective Affiliates may accept deposits from, lend money to, act as trustee under indentures of, and generally engage in any kind of business with, any of the Sellers, any of the Sellers’ Affiliates and any Person who may do business with or own securities of the Sellers or any such Affiliate, all as if the Custodian were not the Custodian and without any duty to account therefor to the Administrative Agent or the holders of any Repurchase Obligations.

4.4. Successor Custodian.

The Custodian may resign at any time by giving written notice thereof to the Sellers and the Administrative Agent. The Custodian may be removed at any time with cause, and upon thirty (30) days written notice without cause, by the Administrative Agent on behalf of the Purchasers. Upon request of the Sellers, so long as no Default or Event of Default exists, the Custodian shall be removed by the Administrative Agent, provided that any such removal without cause at the request of the Seller shall be preceded by thirty (30) days written notice to the Custodian and the Sellers shall pay immediately upon demand all costs and expenses incurred by any Purchaser, the Administrative Agent or the Custodian in connection therewith. Upon any such resignation or removal, the Administrative Agent, at the direction of the Majority Banks, shall have the right to appoint a successor Custodian. Any successor Custodian appointed by the Administrative Agent, provided that no Default or Event of Default exists, shall be satisfactory to the Sellers at the time of appointment. In the case of a retirement or resignation, if no successor Custodian shall have been so appointed by the Administrative Agent (and approved by the Sellers, if applicable), and shall have accepted such appointment, within 60 days after the retiring Custodian’s giving of notice of resignation, then the retiring Custodian shall deliver all Mortgage Assets in its possession to the Administrative Agent and the Custodian shall be discharged from its duties and obligations under this Agreement. After a notice of retirement or resignation has been given by the Custodian and until a successor Custodian shall have been appointed, the Administrative Agent shall pay all reasonable fees and out of pocket expenses owed to the Custodian by the Servicer pursuant to any written agreement between the Custodian and the Servicer, provided, however, that the Sellers shall reimburse the Administrative Agent for all such payments. No such resignation or removal shall be effective until the earlier of (1) the date on which a successor Custodian shall have been appointed, and accepted such appointment, in accordance with this Section 4.4 or (2) the day upon which a period of 60 days has passed after notice of such resignation or removal. Upon the acceptance of any appointment of the Custodian hereunder by a successor Custodian, such successor Custodian shall thereupon succeed to and become vested with all the rights, powers, privileges and duties of the retiring Custodian, and the retiring Custodian shall be discharged from its duties and obligations under this Agreement. The retiring or removed Custodian shall take all steps reasonably necessary to provide for an orderly transfer of the Mortgage Assets and all related documentation to the successor Custodian at the Servicer’s expense. After any retiring Custodian’s resignation or removal hereunder as the Custodian, the provisions of this Article IV shall inure to its benefit as to any actions taken or omitted to be taken by it while it was a Custodian under this Agreement.

4.5. Right of Inspection.

The Custodian shall permit any officer, employee or agent of the Sellers, the Servicer or the Administrative Agent that may so request to visit and inspect the premises on which the custodial duties of the Custodian hereunder are performed, examine the books and records of the Custodian which pertain to such custodial duties, take copies and extracts therefrom, and discuss the performance of such custodial duties with the officers of the Custodian that are responsible therefor, at such time, after reasonable prior written notice to the Custodian, as may be mutually acceptable to the Custodian and such Sellers, Servicer or Administrative Agent during the Custodian’s normal business hours.

4.6. Accounting in Certain Circumstances.

Subject to the provisions of Section 4.2 hereof, in the event that the Custodian, acting in its capacity as custodian for the Administrative Agent, shall receive any money in respect of Mortgage Assets, whether pursuant to Section 3.4 hereof or otherwise, the Custodian shall provide an accounting therefor to the Administrative Agent and the Sellers by the end of the Business Day following the date of receipt thereof, such accounting to include the amount received and shall promptly (but in no event later than the next Business Day) deposit such amounts into the Collection Account and prior to such deposit to be held as Mortgage Assets in favor of the Administrative Agent as provided in Section 3.1; provided, however, that all expenses of the Custodian reasonably allocable to such accounting shall be added to the Repurchase Obligations as expenses of the Custodian. All such funds received after 4:00 p.m. (eastern time) shall be considered to have been received on the following Business Day. All such funds received shall be held uninvested (and the Custodian shall not be liable for interest thereon), unless permitted by the applicable Transaction Document and otherwise instructed by the Servicer, and in such case, funds shall be invested in Eligible Investments specified by the Servicer in such instructions; provided, however, that if the Servicer directs that funds be invested in Eligible Investments, the Servicer shall be required to ensure that all investments must mature on each Settlement Date (as defined in the Repurchase Agreement). The Custodian shall provide such other information in such detail and at such time or times as the Sellers or the Administrative Agent may reasonably request.
