(f) On or prior to 7:00 p.m. New York time, Custodian shall deliver to Purchaser a Cumulative Position Report reflecting all Mortgage Loans held by Custodian as of such time under this Agreement. Section 4. Certification by Custodian; Delivery of Documents. (a) With respect to each Mortgage Loan that Purchaser desires to purchase, Purchaser shall deliver to Custodian a Request for Certification. Upon receipt by Custodian of a Request for Certification, Custodian shall perform the following procedures with respect to each Mortgage Loan listed on such Request for Certification: (i) Custodian shall ascertain whether it is in possession of a Submission Package for each Mortgage Loan identified on a Request for Certification. If Custodian is not in possession of a Submission Package relating to a Mortgage Loan identified on a Request for Certification, Custodian shall annotate its Certification Report in the appropriate space provided with a Mortgage Loan Absentee Code. If Custodian is in possession of Submission Packages delivered by the related Seller which do not relate to any of the Mortgage Loans listed on a Request for Certification, Custodian shall generate an Unidentified Mortgage Loans List and shall deliver such List promptly to Purchaser. Purchaser shall deliver a copy of such Unidentified Mortgage Loans List to such Seller. No action shall be taken by Custodian, other than in accordance with a notice in the form of Exhibit I-2 or Exhibit O, with respect to Mortgage Loans appearing on an Unidentified Mortgage Loans List until any such Mortgage Loans are included in a Request for Certification. -12- (ii) With respect to each Request for Certification Custodian shall: (A) verify the Loan Identification Data appearing in (1) the "LAST NAME" column by comparing such Loan Identification Data to the information in the Mortgage Note and Assignment of Mortgage, (2) the "NOTE DATE" (indicating any Mortgage Note with a date which is greater than 30 days prior with the appropriate exception code), "FACE AMOUNT", "# OF MONTHS TO MATURITY" and "NOTE RATE" columns by comparing such Loan Identification Data to the information in the Mortgage Note and (3) the "MERS IDENTIFICATION NUMBER" column by comparing such Loan Identification Data to the information in the Mortgage Note; (B) if the Program Code indicates a Cash Window Transaction, verify the Loan Identification Data appearing in the "LOAN #" column by comparing the related information in any of the related Applicable Agency Documents; (C) if the Program Code indicates a Cash Window Transaction, Conduit Transaction or Conversion Transaction, verify the Loan Identification Data appearing in the "TAKEOUT INVESTOR", "SALE PRICE", "COMMITMENT #", and "COMMITMENT EXPIRATION DATE" columns by comparing such Loan Identification Data to the information appearing in the Commitment; and (D) if the Program Code indicates a Cash Window Transaction or a Conduit Transaction, verify the Loan Identification Data appearing in the "WAREHOUSE LENDER" column by comparing such Loan Identification Data to the information appearing in the Warehouse Lender's Release or such Seller's Release, as applicable. After applying the applicable procedures set forth in clauses (A), (B) and (C) above, any discrepancies between the Loan Identification Data and documents comprising the Submission Package shall be noted by Custodian on the Exception Report. (b) With respect to each Request for Certification, following completion by Custodian of the procedures set forth in Section (4)(a). (i) Custodian shall review each applicable set of documents comprising the Submission Package and shall ascertain whether (A) each such document is in Custodian's possession, (B) each such document accurately conforms with the Loan Identification Data set forth in Section 4(a)(ii), (C) each such document appears regular on its face, (D) each such document in the Submission Package appears on its face to conform to the requirements of Exhibit A, Exhibit B-l, Exhibit C-1 or Exhibit F, as applicable, (E) unless the Program Code indicates either a Dry Transaction or a Conversion Transaction, the Mortgage Loan is listed on a schedule attached to a Warehouse Lender's Release or a Seller's Release from the related Seller, as the case may be, (F) either (1) if the Release Payment is a dollar amount, the amount appearing in the "RELEASE PAYMENT" column on the Request for Certification is equal to or -13- exceeds the Release Payment, or (2) if the Program Code indicates either a Dry Transaction or a Conversion Transaction, or if the Release Payment is a formula, as indicated in Exhibit G-1, the Custodian need not verify the amount, if any, appearing in the "RELEASE PAYMENT" column and (G) (1) with respect to the wire transfer instructions as set forth in Freddie Mac Form 987 (Wire Transfer Authorization for a Cash Warehouse Delivery) such wire transfer instructions are identical to Purchaser's Wire Instructions to the related Seller or (2) the Payee Number set forth on Fannie Mae Form 1068 (Fixed-Rate, Graduated-Payment, or Growing-Equity Mortgage Loan Schedule) or Fannie Mae Form 1069 (Adjustable-Rate Mortgage Loan Schedule), as applicable, is identical to the Payee Number that has been identified by Purchaser in the Request for Certification. (ii) If Custodian determines that the documents in the Submission Package and the Mortgage Loan to which they relate conform in all respects with Section 4(b)(i), Custodian shall so indicate in the space provided in its Certification Report with a Mortgage Loan Approval Code. If Custodian determines that the documents in a Submission Package and the Mortgage Loan to which they relate conform in all respects with Section 4(b)(i) except that the endorsement of the Mortgage Note is missing, Custodian may, but shall not be obligated to, prepare such endorsement pursuant to the Limited Power of Attorney. If documents in the Submission Package do not conform in all respects with Section 4(b)(i) or are missing and/or do not conform, Custodian shall indicate such on its Exception Report. (c) The Custodian shall have no obligation to provide a Certification Report with respect to (i) any Submission Package received after 11:00 a.m. (New York City time) or (ii) any Submission Packages delivered in excess of 100 Submission Packages without two (2) Business Days prior notice from the related Seller(s) (in any event not to exceed 175 Submission Packages) on any Expected Delivery Date. Provided that the Custodian has received the Submission Packages in accordance with clauses (i) and (ii) above, the Custodian shall prepare and deliver to Purchaser, by 3:00 p.m. (New York City time), the Certification Report. All applicable documents comprising a Submission Package relating to a Mortgage Loan with respect to which Custodian has assigned a Mortgage Loan Approval Code shall be delivered by Custodian in such reasonable order as Custodian may determine, via overnight courier in accordance with the Delivery Instructions on the applicable Delivery Date and under cover of a fully completed Bailee Letter prepared by Custodian. In those cases where a copy of any intervening mortgage assignment, or an unrecorded original of any intervening mortgage assignment are delivered to the Custodian, the related Seller shall cause the original of such instrument to be recorded. If Delivery Instructions direct Custodian to deliver a Submission Package to a location that is not a Takeout Investor's office as listed on Schedule A, which may be amended from time to time by Purchaser, Custodian must receive Purchaser's written consent to make deliveries to such location prior to complying with such Delivery Instructions. Upon receipt of one written approval from Purchaser, such written approval shall, unless Custodian receives a notice from Purchaser to the contrary, be deemed to apply to all Delivery Instructions delivered in the future by the related Seller that list such location. With respect to a Dry Transaction, Custodian must receive Purchaser's consent prior to making each and every delivery of a Dry Submission Package in accordance with the Delivery Instructions. Custodian shall deliver a Delivery Report to the related Seller and, upon request, to Purchaser by facsimile -14- or electronic transmission. Following delivery by Custodian of the applicable portion of a Submission Package to a Takeout Investor, and subsequent to Purchaser's communication to Custodian that the Mortgage Loan has been purchased by the Takeout Investor, all remaining documents comprising such Submission Package shall be held by Custodian for 120 (one hundred twenty) calendar days and then will be delivered by Custodian to the related Seller at such Seller's expense. If, on any Business Day, Custodian assigns a Mortgage Loan Suspension Code to any Submission Package, Custodian shall deliver to the related Seller, by facsimile or electronic transmission, a report detailing each such Suspension Package for which such Mortgage Loan Suspension Code was assigned. All applicable documents comprising a Submission Package relating to a Mortgage Loan with respect to which Custodian has assigned a Mortgage Loan Suspension Code shall be held by Custodian until receipt from the related Seller of instructions. On each Business Day during which a Mortgage Loan shall have a Mortgage Loan Suspension Code assigned to it, such Seller shall instruct Custodian as to the action, if any, Custodian should take with respect to such Mortgage Loan. (d) As outlined in Section 2(d), Custodian shall deliver to Purchaser or the Assignee, no later than 5:30 p.m. New York City time on the related Purchase Date, by facsimile transmission followed by overnight courier to Assignee, a Trust Receipt or Trust Receipts with respect to the Mortgage Loans listed on the Mortgage Loan Schedule(s) attached thereto. The Trust Receipt(s) will represent the Mortgage Loans for which the Custodian has issued a Mortgage Loan Approval Code on any Business Day less any Mortgage Loans as to which the Purchaser has notified Custodian that its interest has been released; provided, however, that the aggregate original principal balance of the Mortgage Loans listed on a Mortgage Loan Schedule shall not exceed an amount determined by Purchaser and agreed to by Custodian, which agreement will not be unreasonably withheld. Each Trust Receipt of a series, as identified by an alphanumeric number thereon, that is delivered by Custodian to Purchaser shall, upon such delivery, supercede and cancel any prior Trust Receipt of the same series. (e) At any time following the delivery of a Trust Receipt, in the event Custodian becomes aware of any defect with respect to such Submission Package or the related forms, including the return of documents to the Custodian from Takeout Investor due to a defect in such documents, the Custodian shall give prompt oral notice of such defect to the Purchaser, followed by a written specification thereof. Section 5. [Reserved]. Section 6. Default. If the related Seller fails to fulfill any of its obligations under the Purchase Agreement, the Electronic Tracking Agreement, if any, or hereunder or in connection with the exercise by Purchaser of any remedy pursuant to Section 3 of the Purchase Agreement then, subject to the provisions of Section 3(c) hereof, Purchaser may, by notice to Custodian and with its prior consent, (a) appoint Custodian as its delegee to complete the endorsements on the Mortgage Notes held by Custodian and to complete and record at Purchaser's expense the related blank Assignments of Mortgages relating to the affected Mortgage Loan in accordance with Purchaser's instructions, when applicable, (b) require Custodian to deliver to Purchaser, Takeout Investor or Successor Servicer the Submission -15- Packages (or any portion thereof specified by Purchaser) in Custodian's possession or under Custodian's control to which the failure relates, and (c) take such actions under the Electronic Tracking Agreement, if any, on behalf of the Purchaser as are necessary to effectuate the foregoing. Section 7. Access to Documents. Upon reasonable prior written notice to Custodian, Purchaser (and if the Mortgage Loans have been assigned, Assignee) and its agents, accountants, attorneys and auditors will be permitted during normal business hours at the Custodian's offices to examine and copy at their expense the Submission Packages, documents, records and other papers in possession of or under the control of Custodian relating to any or all of the Mortgage Loans in which Purchaser has an interest. Upon the request of Purchaser (or, if applicable, Assignee) and at the cost and expense of Purchaser (or, if applicable, Assignee), Custodian shall provide such Purchaser (or, if applicable, Assignee) with copies of the Mortgage Notes, Assignments of Mortgage and other documents in Custodian's possession relating to any of the Mortgage Loans in which Purchaser (or, if applicable, Assignee) has an interest. Section 8. Custodian's Fees and Expenses; Successor Custodian; Standard of Care. (a) It is understood that the Sellers will be charged for Custodian's fees for its services and shall reimburse Custodian for any expense it has incurred under this Agreement in such amounts and in the manner set forth in a separate letter agreement among Sellers and Custodian. Notwithstanding the foregoing, Custodian has no lien on, and shall not attempt to place a lien on, any of the Mortgage Loans or proceeds thereof to secure the payment of its fees. The obligations of each Seller under this Section 8(a) shall survive the resignation or removal of the Custodian hereunder and the termination of this Agreement. (b) Custodian may resign at any time and be discharged of the duties and obligations created by this Agreement by giving not less than sixty (60) days' written notice to Sellers and Purchaser. (c) Such resignation shall take effect upon the earlier of (i) the appointment of a successor Custodian by Purchaser and delivery of all the Submission Packages and any portion of the related documents in Custodian's possession to the successor Custodian, and (ii) the delivery of all the Submission Packages and any portion of the related documents in Custodian's possession to the Purchaser or its designee pursuant to (c) below. (d) In the event of any such resignation, Custodian shall promptly transfer to the successor Custodian all Submission Packages and related documents in Custodian's possession and the successor Custodian shall hold Submission Packages and related documents in accordance with this Agreement. Purchaser shall be responsible for all expenses associated with the transfer of the Submission Packages and any related documents in Custodian's possession and for any fee of the successor Custodian in excess of the fees of the initial Custodian hereunder. The Purchaser shall have 60 days in which to appoint and designate an acceptable successor Custodian. If the Purchaser fails to appoint a successor Custodian within such 60-day period, then Custodian shall deliver possession and custody of the Submission Packages and any related Submission Packages in Custodian's possession to Purchaser at the address specified on the cover page hereof, or if a timely written designation is received by Custodian, to any designee of Purchaser. -16- (e) Custodian shall have responsibility only for the Submission Packages and the contents thereof which have been actually delivered to it and which have not been released to the related Seller, Purchaser, the Agency or Assignee or their respective agent or designee in accordance with this Agreement. The standard of care to be exercised by Custodian in the performance of its duties under this Agreement shall be to exercise the same degree of care as Custodian exercises when it holds mortgage loan documents as security for similar mortgage warehouse loan customers. Custodian is an agent, bailee and custodian only and is not intended to be, nor shall it be construed to be (except only as agent, bailee and custodian), a representative, trustee or fiduciary of or for the related Seller, the Agency, Purchaser or Assignee. (f) Custodian shall incur no liability to any Entity for Custodian's acts or omissions hereunder, except for liabilities which (i) arise from Custodian's gross negligence or willful misconduct or (ii) solely with respect to the Purchaser, which arise from Custodian negligently or intentionally failing to (A) issue an accurate Certification Report; provided, however, any such liability shall not be incurred with respect to the issuance of an inaccurate Certification Report if the defect causing such inaccuracy would not have been ascertainable by the Custodian applying the procedures expressly set forth in this Agreement, (B) timely deliver the Submission Package in accordance with the Delivery Instructions or Purchaser's written instructions, as applicable, (C) prevent the loss, damage or destruction of any document included in a Submission Package when held by Custodian, (D) issue a Trust Receipt which applies to a Mortgage Loan with respect to which the procedures set forth in Section 4 hereof have not been completed by the Custodian in accordance with this Agreement, (E) include a Bailee Letter, including Purchaser's Wire Instructions, in the form of Exhibit I-1, in each Submission Package delivered to a Takeout Investor or a Dry Transaction Takeout Investor, as applicable or (F) include a Notice of Bailment, in the form of Schedule A to Exhibit B-4, including Purchaser's Wire Instructions, in each Submission Package delivered to Fannie Mae; provided, however, Custodian shall have no liability hereunder if Custodian's failure to perform resulted from the inaction or action of any other Entity, other than Entities that are affiliated with Custodian or are acting under the direct control of Custodian. Custodian's liability under this Agreement shall be limited to direct damages resulting from aforesaid. In addition Custodian shall not be liable, directly or indirectly, for (1) any losses, claims, damages, liabilities or expenses which would have been avoided had any Entity making a claim taken reasonable action to mitigate such losses, claims, damages, liabilities or expenses or (2) special, punitive or consequential damages, even if Custodian has been advised of the possibility of such damages; provided, however, that if Custodian's actions or inactions as set forth above result in a decline in the market value of a Mortgage Loan thereby causing direct damages to the Purchaser, such damages shall not be deemed special or consequential damages. (g) Custodian may consult with counsel and shall be entitled to conclusively rely upon the advice of its legal counsel from time to time and shall not be liable for any action or inaction by it in reliance upon such advice. Custodian also shall be entitled to conclusively rely upon any notice, document, correspondence, request or directive received by it from any Seller, Takeout Investor, Purchaser or Assignee, as the case may be, that Custodian believes to be genuine and to have been signed or presented by the proper and duly authorized officer or representative thereof, and shall not be obligated to inquire as to the authority or power of any -17- person so executing or presenting such documents or as to the truthfulness or correctness of any statements set forth therein. (h) Each Seller hereby jointly and severally indemnifies, defends and holds Custodian and its officers, directors, employees, representatives and agents harmless from and against any claim, legal action, liability, obligation, damages, penalty, judgment, suit or loss that is initiated against or incurred by Custodian, including court costs and reasonable attorneys' fees and disbursements, in connection with Custodian's performance of its duties under this Agreement, including those involving ordinary negligence, but excluding those involving gross negligence or willful misconduct of Custodian; such indemnification shall survive the resignation or removal of the Custodian hereunder and the termination of this Agreement. (i) Custodian undertakes to perform such duties and only such duties as are specifically set forth in this Agreement, it being expressly understood that there are no implied duties or obligations hereunder. (j) Custodian shall not be required by any provision of this Agreement to expend or risk its own funds in the performance of its duties under this Agreement if it shall have reasonable grounds for believing that repayment of such funds is not assured to it or indemnity satisfactory to it against such risk or liability. (k) Custodian may rely on the validity of documents and, to the extent permitted hereby, oral communications delivered to it, without investigation as to their authenticity or legal effectiveness and Sellers and Purchaser will jointly and severally hold the Custodian harmless from any claim which may arise or be asserted against the Custodian because of the invalidity of any such documents or oral communications or their failure to fulfill their intended purpose. (l) If the Custodian shall have at any time received conflicting instructions from the Purchaser or a Seller with respect to any of the Custodian's Submission Packages, and the conflict between such instructions cannot be resolved by reference to the terms of this Agreement, the Custodian shall be entitled to rely exclusively on the instructions of the Purchaser. (m) If Custodian requests written instructions from any Seller or Purchaser, as the case may be, with respect to any act, action or failure to act in connection with this Agreement, Custodian shall be entitled to refrain from taking such action unless and until Custodian receives written instructions from such Seller or Purchaser, as the case may be. Section 9. Assignment by Purchaser. Purchaser hereby notifies Custodian that Purchaser may assign, as of the date of the purchase of all of its right, title and interest in and to all Mortgage Loans purchased by Purchaser pursuant to the Purchase Agreement and all rights of Purchaser under the Purchase Agreement, this Agreement and the Electronic Tracking Agreement, if any, in respect of such Mortgage Loans represented thereby to Assignee, subject only to an obligation on the part of Assignee to deliver each such Mortgage Loan to Custodian or to Purchaser to permit Custodian, Purchaser or its designee to make delivery thereof to Takeout Investor, but not otherwise. Each Seller hereby irrevocably consents to such assignment. -18- Assignment by Purchaser of the Mortgage Loans as provided in this Section 9 shall not release Purchaser from its obligations otherwise under this Agreement. Subject to any limitations in any agreement between Assignee and Purchaser, Assignee may, upon notice of Purchaser's default as provided in Section 3(b) hereof, directly enforce and exercise such rights under this Agreement that have been assigned or pledged to it and, until otherwise notified by Assignee, Purchaser shall no longer have any of such rights. Custodian shall assume that any assignment from Purchaser to Assignee is subject to no limitations that are not expressly set forth in this Agreement. Section 10. Insurance. Custodian shall, at its own expense, maintain at all times during the existence of this Agreement such (a) fidelity insurance, (b) theft of documents insurance, (c) forgery insurance and (d) errors and omissions insurance as Custodian deems, from time to time appropriate. Section 11. Delivery of Submission Packages. Prior to any shipment of a Mortgage Loan hereunder, Custodian shall have received from the related Seller written instructions as to the method of shipment and shipper(s) the Custodian is directed to utilize in connection with the delivery of Submission Packages related to Mortgage Loans in the performance of the Custodian's duties hereunder. The applicable Seller shall select shipper(s) from a list of shippers, approved by both Custodian and Purchaser, provided by Purchaser to such Seller. Furthermore, the related Seller shall provide Custodian Delivery Instructions by 11:00 a.m. New York City time on the Delivery Date for same day shipment together with an electronic transmission of such delivery instructions. The applicable Seller will arrange for the provision of such services at its sole cost and expense (or, at the Custodian's option, reimburse the Custodian for all costs and expenses incurred by the Custodian consistent with such instructions) and will maintain such insurance against loss or damage to Submission Packages as the applicable Seller deems appropriate. It is expressly agreed that in no event shall the Custodian have any liability for any losses or damages to any person, including without limitation, the Sellers, arising out of actions of the Custodian consistent with instructions of the Seller (including, without limitation, losses or damages arising out of non-performance or faulty performance by a shipper). Any delivery of Submission Packages under this Agreement shall be by personal delivery, recognized courier delivery service, or registered or certified first class mail, postage prepaid, return receipt requested, as designated by the related Seller. In the event Custodian does not receive such written instructions, Custodian shall be authorized to use any nationally recognized courier service. In no event shall Custodian, without the prior consent of Purchaser, permit delivery to be made to any Seller or an agent of any Seller. Section 12. Representations, Warranties and Covenants. (a) By Custodian.
