The Final Mortgage Loan Schedule shall be delivered to the Purchaser on the Closing Date, shall be attached to this Agreement as Schedule B. If there are no changes to the Preliminary Mortgage Loan Schedule, the Preliminary Mortgage Loan Schedule shall be the Final Mortgage Loan Schedule for all purposes hereof.

SECTION 4. Mortgage Loan Transfer.

(a) The Purchaser will be entitled to all scheduled payments of principal and interest on the Mortgage Loans due after the Cut-off Date (regardless of when actually collected) and all payments thereof other than scheduled payments of principal and interest received after the Cut-off Date. The Seller will be entitled to all scheduled payments of principal and interest on the Mortgage Loans due on or before the Cut-off Date (including payments collected after the Cut-off Date) and all payments thereof other than scheduled payments of principal and interest on the Mortgage Loans received on or before the Cut-off Date. Such principal amounts and any interest thereon belonging to the Seller as described above will not be included in the aggregate outstanding principal balance of the Mortgage Loans as of the Cut-off Date as set forth on the Mortgage Loan Schedule.

(b) Pursuant to various conveyancing documents to be executed on the Closing Date and pursuant to the Trust, Pooling and Servicing Agreement, the Purchaser will assign on the Closing Date all of its right, title and interest in and to the Mortgage Loans and the other assets set forth in Section 2(d) hereof, to the Trustee, on behalf of the Trust, for the benefit of the Certificateholders. In connection with the transfer and assignment of the Mortgage Loans, the Seller has delivered or will deliver or cause to be delivered to the Trustee by the Closing Date or such later date as is agreed to by the Purchaser and the Seller (each of the Closing Date and such later date is referred to as a "Mortgage File Delivery Date"), the items of each Mortgage File. The Seller shall take, or cause the applicable Servicer to take, all actions specified in Section 2.01(c) of the Trust, Pooling and Servicing Agreement in the manner specified therein.

(c) The Seller and the Purchaser acknowledge hereunder that all of the Mortgage Loans and the related servicing (including the rights of the Seller under the Servicing Agreements) will ultimately be assigned to the Trust or Trustee, on behalf of the Trust, for the benefit of the Certificateholders, on the date hereof.

SECTION 5. Examination of Mortgage Files.

(a) On or before the Mortgage File Delivery Date, the Seller will have made the Mortgage Files available to the Purchaser or its agent for examination which may be at the offices of the Trustee or the Seller and/or the Seller's custodian. The fact that the Purchaser or its agent has conducted or has failed to conduct any partial or complete examination of the Mortgage Files shall not affect the Purchaser's rights to demand cure, repurchase, substitution or other relief as provided in this Agreement. In furtherance of the foregoing, the Seller shall make the Mortgage Files available to the Purchaser or its agent from time to time so as to permit the Purchaser to confirm the Seller's compliance with the delivery and recordation requirements of this Agreement and the Trust, Pooling and Servicing Agreement. In addition, upon request of the Purchaser, the Seller agrees to provide to the Purchaser, the Underwriters and to any investors or prospective investors in the Certificates information regarding the Mortgage Loans and their servicing, to make the Mortgage Files available to the Purchaser and the Underwriters (which may be at the offices of the Seller and/or the Seller's custodian) and to make available personnel knowledgeable about the Mortgage Loans for discussions with the Purchaser and the Underwriters, upon reasonable request during regular business hours, sufficient to permit the Purchaser and the Underwriters to conduct such due diligence as any such party reasonably believes is appropriate.

(b) Pursuant to the Trust, Pooling and Servicing Agreement, on the Closing Date the Trustee, for the benefit of the Trust and the Certificateholders, will review certain items of the Mortgage Files and will deliver to the Seller a certification in the form attached as Exhibit C-1 to the Trust, Pooling and Servicing Agreement.

(c) Pursuant to the Trust, Pooling and Servicing Agreement, the Trustee will review the Mortgage Files within 90 and again within 180 days of the Closing Date and will deliver to the Seller and the Master Servicer an interim and a final certification, respectively, substantially in the forms of Exhibits C-2 and C-3, as applicable, to the Trust, Pooling, and Servicing Agreement. If the Trustee is unable to deliver a certification with respect to the items required by Section 2.01(b) of the Trust, Pooling and Servicing Agreement because any document is missing, has not been executed or appears to be unrelated, determined on the basis of the Mortgagor name, original principal balance and loan number, to the Mortgage Loans identified in Exhibit B of the Trust, Pooling and Servicing Agreement or appears to be defective on its face, upon notification by the Trustee or the Custodian as its agent, the Seller shall correct or cure any such defect within 90 days from the date of notice from the Trustee (or the Custodian) of the defect or, in the case of a defect in connection with a final certification of the Trustee, shall deliver to the Trustee an Opinion of Counsel to the effect that such defect does not materially or adversely affect the interests of the Trust or the Certificateholders in such Mortgage Loan. If the Seller is unable to cure such defect within such period, and if such defect materially and adversely affects the interests of the Trust or the Certificateholders in the related Mortgage Loan, the Seller will, in accordance with the terms of the Trust, Pooling and Servicing Agreement, within 90 days of notice, purchase the related Mortgage Loan at the Repurchase Price and in accordance with Section 2.02(c) of the Trust, Pooling and Servicing Agreement. The foregoing repurchase obligation shall not apply in the event that the Seller cannot deliver such original or copy of any document submitted for recording to the appropriate recording office in the applicable jurisdiction because such document has not been returned by such office; provided that the Seller shall instead deliver a recording receipt of such recording office or, if such receipt is not available, an Officer's Certificate confirming that such documents have been accepted for recording, and delivery to the Trustee (or the Custodian, as its agent) shall be effected by the Seller within thirty days of its receipt of the original recorded document.

(d) In lieu of purchasing a Mortgage Loan pursuant to Section 5(c) hereof, the Seller may deliver a Substitute Mortgage Loan in accordance with Section 2.04 of the Trust, Pooling and Servicing Agreement, including delivery of the cash specified therein; provided, however, that delivery of a Substitute Mortgage Loan in lieu of a purchase pursuant to Section 5(c) hereof and Section 2.02 of the Trust, Pooling and Servicing Agreement, shall not be permitted after the two-year period beginning with the Start-up Day, or to the extent otherwise prohibited pursuant to Section 2.04 of the Trust, Pooling and Servicing Agreement. At the time of any substitution, the Seller shall, in accordance with the provisions of Section 2.04 of the Trust, Pooling and Servicing Agreement, deliver or cause to be delivered the Substitute Mortgage Loan, the related Mortgage File and any other documents and payments required to be delivered in connection with a substitution pursuant to the Trust, Pooling and Servicing Agreement. At the time of any purchase or substitution, the Trustee shall, in accordance with the provisions of Section 2.04 of the Trust, Pooling and Servicing Agreement, (i) assign to the Seller and cause the Trustee to release the documents (including, but not limited to, the Mortgage, Mortgage Note and other contents of the Mortgage File) in the possession of the Trustee relating to the repurchased or substituted Mortgage Loan and (ii) execute and deliver such instruments of transfer or assignment, in each case without recourse, as shall be necessary to vest in the Seller title to such repurchased or substituted Mortgage Loan.

SECTION 6. Recordation of Assignments of Mortgage, Etc.

(a) The Seller will, with respect to each Non-MERS Mortgage Loan (other than a Cooperative Loan), promptly after the Closing Date at its expense, cause each Mortgage and each assignment of Mortgage from the Seller to the Trustee, and all unrecorded intervening assignments, if any, delivered on or prior to the Closing Date, to be recorded in all recording offices in the jurisdictions where the related Mortgaged Properties are located; provided, however, the Seller need not cause to be recorded any assignment which relates to a Mortgage Loan in any jurisdiction under the laws of which, as evidenced by an Opinion of Counsel delivered by the Seller to the Trustee and the Rating Agencies, the recordation of such assignment is not necessary to protect the Trustee's interest in the related Mortgage Loan; provided, however, notwithstanding the delivery of any Opinion of Counsel, each assignment of Mortgage with respect to a NON-MERS Mortgage Loan (other than a Cooperative Loan) shall be submitted for recording by the Seller in the manner described above, at no expense to the Trust or Trustee, upon the earliest to occur of (i) reasonable direction by the Holders of Certificates evidencing Fractional Undivided Interests aggregating not less than 51% of the Trust, (ii) the occurrence of a bankruptcy or insolvency relating to the Seller or the Purchaser, or (iii) with respect to any one assignment of Mortgage, the occurrence of a bankruptcy, insolvency or foreclosure relating to the Mortgagor under the related Mortgage.

While each such Mortgage or assignment is being recorded, if necessary, the Seller shall leave or cause to be left with the Trustee a certified copy of such Mortgage or assignment. In the event that, within 180 days of the Closing Date, the Trustee has not received an Opinion of Counsel as described above or received evidence of recording with respect to each Mortgage Loan delivered to the Purchaser pursuant to the terms hereof or as set forth above, the failure to provide evidence of recording or such Opinion of Counsel shall be considered a material defect, and the provisions of Section 5(c) and (d) shall apply. All customary recording fees and reasonable expenses relating to the recordation of the assignments of mortgage to the Trustee or the Opinion of Counsel, as the case may be, shall be borne by the Seller.

With respect to each Cooperative Loan, the Seller will take, or cause the applicable Servicer to take, at the expense of the Seller and with the cooperation of the Seller, the Trustee and the Master Servicer, such actions as are necessary under applicable law in order to perfect the interest of the Trust in the related Mortgaged Property.

With respect to each MERS Mortgage Loan, the Seller will take, or cause the applicable Servicer to take, at the expense of the Seller and at the direction and with the cooperation of the Seller, the Trustee and the Master Servicer, such actions as are necessary to cause the Trust to be clearly identified as the owner of each such Mortgage Loan on the records of MERS for purposes of the system of recording transfers of beneficial ownership of mortgages maintained by MERS.

In addition, in instances where a title insurance policy is required to be delivered to the Trustee, as specified in Section 2.01(b) of the Trust, Pooling and Servicing Agreement, and is not so delivered, the Seller will provide a copy of such title insurance policy to the Trustee, or to the Custodian on behalf of the Trustee, as promptly as practicable after the execution and delivery hereof, but in any case within 180 days of the Closing Date.

For Mortgage Loans (if any) that have been prepaid in full after the Cut-Off Date and prior to the Closing Date, the Seller, in lieu of delivering the above documents, shall comply with Section 2.01(e) of the Trust, Pooling and Servicing Agreement.

(b) It is the express intent of the parties hereto that the conveyance of the Mortgage Loans by the Seller to the Purchaser, as contemplated by this Agreement be, and be treated as, a sale. It is, further, not the intention of the parties that such conveyance be deemed a pledge of the Mortgage Loans by the Seller to the Purchaser to secure a debt or other obligation of the Seller. However, in the event that, notwithstanding the intent of the parties, the Mortgage Loans are held by a court to continue to be property of the Seller, then (a) this Agreement shall also be deemed to be a security agreement within the meaning of Articles 8 and 9 of the applicable Uniform Commercial Code; (b) the transfer of the Mortgage Loans provided for herein shall be deemed to be a grant by the Seller to the Purchaser of a security interest in all of the Seller's right, title and interest in and to the Mortgage Loans and all amounts payable to the holders of the Mortgage Loans in accordance with the terms thereof and all proceeds of the conversion, voluntary or involuntary, of the foregoing into cash, instruments, securities or other property, to the extent the Purchaser would otherwise be entitled to own such Mortgage Loans and proceeds pursuant to Section 4 hereof, including all amounts, other than investment earnings, from time to time held or invested in any accounts created pursuant to the Trust, Pooling and Servicing Agreement, whether in the form of cash, instruments, securities or other property; (c) the possession by the Purchaser or the Trustee of Mortgage Notes and such other items of property as constitute instruments, money, negotiable documents or chattel paper shall be deemed to be "possession by the secured party" for purposes of perfecting the security interest pursuant to Section 9-313 (or comparable provision) of the applicable Uniform Commercial Code; and (d) notifications to persons holding such property, and acknowledgments, receipts or confirmations from persons holding such property, shall be deemed notifications to, or acknowledgments, receipts or confirmations from, financial intermediaries, bailees or agents (as applicable) of the Purchaser for the purpose of perfecting such security interest under applicable law. Any assignment of the interest of the Purchaser pursuant to any provision hereof or pursuant to the Trust, Pooling and Servicing Agreement shall also be deemed to be an assignment of any security interest created hereby. The Seller and the Purchaser shall, to the extent consistent with this Agreement, take such actions as may be reasonably necessary to ensure that, if this Agreement were deemed to create a security interest in the Mortgage Loans, such security interest would be deemed to be a perfected security interest of first priority under applicable law and will be maintained as such throughout the term of the Trust, Pooling and Servicing Agreement.

SECTION 7. Representations and Warranties of the Seller Concerning the Mortgage Loans. The Seller hereby makes the representations and warranties set forth in Exhibit 3 hereto applicable to the Mortgage Loans, as of the Cut-off Date or, if applicable, such other date as may be specified therein.

Upon discovery or receipt of notice by the Seller, the Purchaser or the Trustee of a breach of any representation or warranty of the Seller set forth in Exhibit 3 hereto which materially and adversely affects the value of the interests of the Purchaser, the Trust, the Certificateholders or the Trustee in any of the Mortgage Loans delivered to the Purchaser pursuant to this Agreement, the party discovering or receiving notice of such breach shall give prompt written notice to the others. In the case of any such breach of a representation or warranty set forth in Exhibit 3 hereto, within 90 days from the earliest of the date of receipt of notice or discovery by the Seller of such breach, the Seller will (i) cure such breach in all material respects, (ii) purchase the affected Mortgage Loan at the applicable Repurchase Price or (iii) if within two years of the Closing Date, substitute a qualifying Substitute Mortgage Loan in exchange for such Mortgage Loan in the case of clauses (ii) and (iii), in accordance with Section 5(c) or 5(d) hereof, as applicable.

Any cause of action against the Seller or relating to or arising out of a breach by the Seller of any representations and warranties made in this Section 7 shall accrue as to any Mortgage Loan upon (i) discovery of such breach by the Seller or notice thereof by the party discovering such breach and (ii) failure by the Seller to cure such breach, purchase such Mortgage Loan or substitute a qualifying Substitute Mortgage Loan pursuant to the terms hereof.

Notwithstanding whether any representation or warranty made by the Seller in Exhibit 3 hereof is made only to the best of the Seller’s knowledge, the Seller shall be obligated under this Section 7 to repurchase any Mortgage Loan with respect to which such representation or warranty was untrue as of the Cut-off Date, the Closing Date, or otherwise, as applicable, irrespective of the Seller’s lack of knowledge thereof.

(e) this Agreement has been duly executed and delivered by the Seller and, assuming due authorization, execution and delivery by the Purchaser, constitutes a valid and binding obligation of the Seller enforceable against it in accordance with its terms (subject to applicable bankruptcy and insolvency laws and other similar laws affecting the enforcement of the rights of creditors generally); and

(f) there are no actions, suits or proceedings pending or, to the knowledge of the Seller, threatened against the Seller, before or by any court, administrative agency, arbitrator or governmental body (i) with respect to any of the transactions contemplated by this Agreement or (ii) with respect to any other matter which in the judgment of the Seller will be determined adversely to the Seller and will if determined adversely to the Seller materially and adversely affect the Seller's ability to perform its obligations under this Agreement; and the Seller is not in default with respect to any order of any court, administrative agency, arbitrator or governmental body so as to materially and adversely affect the transactions contemplated by this Agreement.

SELLER'S REPRESENTATIONS AND
WARRANTIES RELATING TO
THE MORTGAGE LOANS

Mortgage Loan, as of the Cut-off Date or such other date specifically set forth herein, and with respect to representations (i) and (xxi) listed below, as of the Closing Date:

(i)

(a) The information set forth in the Final Mortgage Loan Schedule is complete, true and correct in all material respects and (b) the Mortgage File with respect to each Mortgage Loan has been delivered to the Trustee or its designee and each Mortgage File contains the documents required to be contained therein.

(ii)

Approximately 0.10% and 0.04% of the Group 1 Mortgage Loans and the Group 4 Mortgage Loans, respectively, by Scheduled Principal Balance are 30 or more days delinquent. None of the Group 2 Mortgage Loans, the Group 3 Mortgage Loans or the Group 5 Mortgage Loans by Scheduled Principal Balance are 30 or more days delinquent. The Seller has not advanced funds to, or induced, solicited or knowingly received any advance of funds from a party other than the owner of the Mortgaged Property subject to the Mortgage, directly or indirectly, for the payment of any amount required by the Mortgage Loan.

(iii)

To the best of the Seller's knowledge, there are no delinquent taxes, ground rents, water charges, sewer rents, assessments, insurance premiums, leasehold payments, including assessments payable in future installments or other outstanding charges affecting the related Mortgaged Property.

(iv)

The terms of the Mortgage Note and the Mortgage (including with respect to provisions relating to any Additional Collateral (if applicable)) have not been impaired, waived, altered or modified in any respect, except by written instruments which have been recorded, if necessary to protect the interests of the Trust, and which are included in the Mortgage File, the substance of which waiver, alteration or modification has been approved by the primary mortgage guaranty insurer, if any, and by the title insurer, to the extent required by the related policy and is reflected on the Mortgage Loan Schedule. Except for any modification agreement or similar document contained in the Mortgage File permitting a borrower to modify his loan, no instrument of waiver, alteration or modification has been executed, and no Mortgagor has been released, in whole or in part, except in connection with an assumption agreement approved by the primary mortgage insurer, if any, and title insurer, to the extent required by the policy, and which assumption agreement is part of the Mortgage File.

(v)

The Mortgage Note and the Mortgage (including with respect to provisions relating to any Additional Collateral (if applicable)) are not subject to any right of rescission, set-off, counterclaim or defense, including the defense of usury, nor will the operation of any of the terms of the Mortgage Note and Mortgage, or the exercise of any right thereunder, render the Mortgage unenforceable, in whole or in part, or subject to any right of rescission, set-off, counterclaim or defense, including the defense of usury, and to the Seller's knowledge no such right of rescission, set-off, counterclaim or defense has been asserted with respect thereto.

(vi)

All buildings upon the Mortgaged Property are insured by a generally acceptable insurer against loss by fire, hazards of extended coverage and such other hazards as are customary in the area where the Mortgaged Property is located. All such insurance policies contain a standard mortgagee clause naming the Master Servicer or the applicable Servicer, their successors and assigns as mortgagee and to the Seller's knowledge all premiums thereon have been paid. If upon origination of the Mortgage Loan, the Mortgaged Property was in an area identified in the Federal Register by the Federal Emergency Management Agency as having special flood hazards (and such flood insurance has been made available) a flood insurance policy meeting the requirements of the current guidelines of the Federal Insurance Administration is in effect which policy conforms to the requirements of ▇▇▇▇▇▇ ▇▇▇ or ▇▇▇▇▇▇▇ Mac. The Mortgage obligates the Mortgagor thereunder to maintain all such insurance at Mortgagor's cost and expense, and on the Mortgagor's failure to do so, authorizes the holder of the Mortgage to maintain such insurance at Mortgagor's cost and expense and to seek reimbursement therefor from the Mortgagor.

(vii)

The Mortgage Loan is not a loan (A) subject to 12 CFR Part 226.31, 12 CFR Part 226.32 or 12 CFR Part 226.34 of Regulation Z, the regulation implementing TILA, which implements the Home Ownership and Equity Protection Act of 1994, as amended, (B)(w) a "High-Cost Home Loan" as defined in the New Jersey Home Ownership Act effective November 27, 2003, (x) a "High-Cost Home Loan" as defined in the New Mexico Home Loan Protection Act effective January 1, 2004, (y) a "High Cost Loan" or "Covered Loan" (as such terms are defined in the current S&P's LEVELS(R)Glossary), or (z) governed by the Georgia Fair Lending Act, if such Mortgage Loan was originated on or after October 1, 2002 through May 6, 2003 or (C) classified and/or defined as a "high cost" loan or "predatory," "high cost," "threshold" or "covered" lending under any other state, federal or local law. The Mortgage Loan at the time it was made otherwise complied in all material respects with any and all requirements of any federal, state or local law including, but not limited to, all predatory lending laws, usury, truth in lending, real estate settlement procedures (including the Real Estate Settlement Procedures Act of 1974, as amended), consumer credit protection, equal credit opportunity or disclosure laws applicable to such Mortgage Loan.

(viii)

The Mortgage has not been satisfied, canceled or subordinated, or rescinded, in whole or in part, and the Mortgaged Property has not been released from the lien of the Mortgage except for a release that does not materially impair the security of the Mortgage Loan or is reflected in the loan-to-value ratio, in whole or in part, nor has any instrument been executed that would effect any such release, cancellation, subordination or rescission unless payoff funds have been deposited in the custodial account at closing.

(ix)

The Mortgage is a valid, existing and enforceable first lien on the Mortgaged Property, including all improvements on the Mortgaged Property subject only to (A) the lien of current real property taxes and assessments not yet due and payable, (B) covenants, conditions and restrictions, rights of way, easements and other matters of the public record as of the date of recording being acceptable to mortgage lending institutions generally and specifically referred to in a lender's title insurance policy delivered to the originator of the Mortgage Loan and which do not adversely affect the Appraised Value of the Mortgaged Property, and (C) other matters to which like properties are commonly subject which do not materially interfere with the benefits of the security intended to be provided by the Mortgage or the use, enjoyment, value or marketability of the related Mortgaged Property. Any security agreement, chattel mortgage or equivalent document related to and delivered in connection with the Mortgage establishes and creates a valid, existing and enforceable first lien and first priority security interest on the property described therein and the Seller has full right to sell and assign the same to the Purchaser.

(x)

The Mortgage Note and the related Mortgage are genuine and each is the legal, valid and binding obligation of the maker thereof, enforceable in accordance with its terms, except as the enforceability thereof may be limited by bankruptcy, insolvency, or reorganization or other laws relating to the rights of creditors.

(xi)	All parties to the Mortgage Note and the Mortgage had legal capacity to enter into the Mortgage Loan and to execute and deliver the Mortgage Note and the Mortgage, and the Mortgage Note and the Mortgage have been duly and properly executed by such parties.

(xii)

The proceeds of the Mortgage Loan have been fully disbursed, there is no requirement for future advances thereunder and any and all requirements as to completion of any on-site or off-site improvements and as to disbursements of any escrow funds therefor have been complied with (except for escrow funds for exterior items which could not be completed due to weather and escrow funds for the completion of swimming pools); and all costs, fees and expenses incurred in making, closing or recording the Mortgage Loan have been paid, except recording fees with respect to Mortgages not recorded as of the Closing Date.

(xiii)

The Seller has acquired its ownership of each Mortgage Loan in good faith without notice of any adverse claim, and as of the Closing Date, the Mortgage Note and the Mortgage are not assigned or pledged, and immediately prior to the sale of the Mortgage Loan to the Purchaser, the Seller was the sole owner thereof and with full right to transfer and sell the Mortgage Loan to the Purchaser free and clear of any encumbrance, equity, lien, pledge, charge, claim or security interest and with full right and authority subject to no interest or participation of, or agreement with, any other party, to sell and assign each Mortgage Loan pursuant to this Agreement.

(xiv)

To the Seller's best knowledge, the Seller or, if the Mortgage Loan was not originated by the Seller, the originator is or was (or, during the period in which they held and disposed of such interest, were) (A) in compliance with any and all applicable licensing requirements of the laws of the state wherein the Mortgaged Property is located, and (B) either (i) organized under the laws of such state, or (ii) qualified to do business in such state, or (iii) federal savings and loan associations or national banks or subsidiaries having preemptive authority under federal law or under applicable state law to engage in business in such state without qualification, or (iv) not doing business in such state.

(xv)

The Mortgage Loan is covered by an ALTA lender's title insurance policy acceptable to ▇▇▇▇▇▇ ▇▇▇ or ▇▇▇▇▇▇▇ Mac, issued by a title insurer acceptable to ▇▇▇▇▇▇ Mae or ▇▇▇▇▇▇▇ Mac and qualified to do business in the jurisdiction where the Mortgaged Property is located, insuring (subject to the exceptions contained in (ix)(A) through (C) above) the originator or the Seller, their respective successors and assigns as to the first priority lien of the Mortgage in the original principal amount of the Mortgage Loan. Additionally, such lender's title insurance policy affirmatively insures ingress and egress, and against encroachments by or upon the Mortgaged Property or any interest therein. The Seller is the sole insured of such lender's title insurance policy, and such lender's title insurance policy is in full force and effect and will be in full force and effect upon the consummation of the transactions contemplated by this Agreement. No claims have been made under such lender's title insurance policy, and no prior holder of the related Mortgage, including the Seller, has done, by act or omission, anything which would impair the coverage of such lender's title insurance policy.

(xvi)

There is no default, breach, violation or event of acceleration existing under the Mortgage or the Mortgage Note and no event which, with the passage of time or with notice and the expiration of any grace or cure period, would constitute a default, breach, violation or event of acceleration, and the Seller has not waived any default, breach, violation or event of acceleration.

(xvii)

To the best of the Seller's knowledge, there are no mechanics' or similar liens or claims which have been filed for work, labor or material (and no rights are outstanding that under law could give rise to such lien) affecting the related Mortgaged Property which are or may be liens prior to, or equal or on parity with, the lien of the related Mortgage.

(xviii)

To the Seller's best knowledge, all improvements which were considered in determining the Appraised Value of the related Mortgaged Property lay wholly within the boundaries and building restriction lines of the Mortgaged Property, and no improvements on adjoining properties encroach upon the Mortgaged Property.

(xix)

The Mortgage Loan was originated by the Seller or a subsidiary of the Seller or was purchased by the Seller from a third party, each of which was, at the time of origination, (A) a ▇▇▇▇▇▇ ▇▇▇-approved or ▇▇▇▇▇▇▇ Mac-approved seller/servicer and (B) a U.S. Department of Housing and Urban Development approved mortgage banker, or a savings and loan association, a savings bank, a commercial bank or similar banking institution which is supervised and examined by a federal or state authority. Each Mortgage Note has a Mortgage Rate that adjusts periodically (not always in correlation to the index calculation term), based on the One-Month LIBOR, Six-Month LIBOR, One-Year LIBOR or One-Year U.S. Treasury Index (as each is defined in the Prospectus Supplement) index, except that some Mortgage Loans first adjust after an initial period of three, five, seven or ten years following origination.

(xx)

The origination practices used by the Seller or the originator of the Mortgage Loan and the collection practices used by the Master Servicer or the applicable Servicer with respect to each Mortgage Note and Mortgage have been in all respects legal, proper, prudent and customary in the mortgage origination and servicing business. With respect to escrow deposits and escrow payments, if any, all such payments are in the possession of, or under the control of, the applicable Servicer and there exist no deficiencies in connection therewith for which customary arrangements for repayment thereof have not been made.

(xxi)

The Mortgaged Property is undamaged by waste, fire, earthquake or earth movement, windstorm, flood, tornado or other casualty, so as to have a material adverse effect on the value of the related Mortgaged Property as security for the related Mortgage Loan or the use for which the premises were intended and there is no proceeding pending for the total or partial condemnation thereof.

(xxii)

The Mortgage contains customary and enforceable provisions such as to render the rights and remedies of the holder thereof adequate for the realization against the Mortgaged Property of the benefits of the security provided thereby, including, (A) in the case of a Mortgage designated as a deed of trust, by trustee's sale, and (B) otherwise by judicial foreclosure. There is no other exemption available to the Mortgagor which would interfere with the right to sell the Mortgaged Property at a trustee's sale or the right to foreclose the Mortgage.

(xxiii)

The Mortgage Loan was underwritten generally in accordance with either (i) the Seller's underwriting standards, (ii) in the case of a Mortgage Loan acquired from First Republic Bank, First Republic Bank's underwriting standards or (iii) in the case of a Mortgage Loan acquired from a bulk seller, the related bulk seller's underwriting standards, in each case as in effect at the time the Mortgage Loan was originated.

(xxiv)

The mortgage file in possession of the related Servicer contains an appraisal of the related Mortgaged Property signed prior to the approval of the Mortgage Loan application by a qualified appraiser, duly appointed by the originator of the Mortgage Loan, who had no interest, direct or indirect in the Mortgaged Property or in any loan made on the security thereof, and whose compensation is not affected by the approval or disapproval of the Mortgage Loan.

(xxv)

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

(xxvi)

No Mortgage Loan contains provisions (A) pursuant to which Scheduled Payments are paid or partially paid with funds deposited in any separate account established by the Seller, the Mortgagor, or anyone on behalf of the Mortgagor or paid by any source other than the Mortgagor or (B) permitting a temporary "buydown" of the related Mortgage Rate. No Mortgage Loan was a graduated payment mortgage loan as of the date of its origination. No Mortgage Loan has a shared appreciation or other contingent interest feature.

(xxvii)

No Mortgage Loan had a Loan-To-Value Ratio in excess of 100%. The portion of the unpaid principal balance of the Mortgage Loan which is in excess of 80% of the Loan-to-Value Ratio either (a) has Additional Collateral or (b) is and will be insured as to payment defaults under a Primary Mortgage Insurance Policy issued by primary mortgage insurer licensed to do business in the state in which the Mortgaged Property is located and acceptable to ▇▇▇▇▇▇ ▇▇▇ or ▇▇▇▇▇▇▇ Mac as of the Closing Date, so as to reduce the Mortgagee's exposure in accordance with the standards of ▇▇▇▇▇▇ Mae or ▇▇▇▇▇▇▇ Mac and applicable law. All provisions of such Primary Mortgage Insurance Policy have been and are being complied with; such policy is valid and in full force and effect and all premiums due thereunder have been paid.

(xxviii)

Except for any Additional Collateral Mortgage Loans, the Mortgage Note is not and has not been secured by any collateral, pledged account, or other security except the lien of the Mortgage, and the security interest of any applicable security agreement or chattel mortgage referred to above.

(xxix)

[Reserved].

(xxx)

The Mortgaged Property is lawfully occupied under applicable law. All inspections, licenses and certificates required to be made or issued with respect to all occupied portions of the related Mortgaged Property and, with respect to the use and occupancy of the same, including but not limited to certificates of occupancy, had been made or obtained from the appropriate authorities.

(xxxi)

No defense against coverage under any Primary Mortgage Insurance Policy (including, without limitation, any exclusions, denials or defenses which would limit or reduce the availability of the timely payment of the full amount of the loss otherwise due thereunder to the insured) exists arising out of actions, representations, errors, omissions, negligence, or fraud of the Seller, and the Seller is not aware of any fact that could reasonably lead the Seller to believe that any such defense exists arising out of the actions, representations, errors, omissions, negligence or fraud of the related Mortgagor or any party involved in the application for such coverage.

(xxxii)

Each assignment of Mortgage is in recordable form, is acceptable for recording under the laws of the jurisdiction in which the Mortgaged Property is located and includes all applicable recording information, except where the related original Mortgage has been delivered for recording to the appropriate public recording office but has not yet been returned to the Seller.

(xxxiii)

If the Mortgaged Property is a condominium unit or a planned unit development (other than a de minimis planned unit development) such condominium or planned unit development project meets ▇▇▇▇▇▇ Mae or ▇▇▇▇▇▇▇ Mac eligibility requirements.

(xxxiv)

Each Mortgage is a "qualified mortgage" for purposes of the REMIC provisions of the Code.

(xxxv)

To the Seller's best knowledge, no fraud was committed by the originator of the Mortgage Loan and the Seller is not aware of any fact that would reasonably lead the Seller to believe that any Mortgagor had committed fraud in connection with the origination of such Mortgage Loan.

(xxxvi)

The Mortgagor has not notified the Seller, and the Seller has no knowledge of any relief requested or allowed to the Mortgagor under the Relief Act.

(xxxvii)

The Seller has no knowledge of any toxic or hazardous substances affecting the Mortgaged Property or any violation of any local, state, or federal environmental law, rule, or regulation. The Seller has no knowledge of any pending action or proceeding directly involving any Mortgaged Property in which compliance with any environmental law, rule, or regulation is an issue.

(xxxviii)

As to any Additional Collateral Mortgage Loan, such Mortgage Loan is secured by a perfected first priority security interest in the related Additional Collateral.

(xxxix)

As to any Additional Collateral Mortgage Loan, the applicable pledge agreement is in place, is genuine and is the legal, valid and binding obligation of the maker thereof, enforceable in accordance with its terms subject to bankruptcy, insolvency and other laws of general application affecting the rights of creditors.

(xl)

With respect to each Cooperative Loan (i) there is no provision in the related proprietary lease which requires the related Mortgagor to offer for sale the shares owned by such Mortgagor first to the Cooperative Corporation for a price less than the outstanding amount of the Cooperative Loan, (ii) there is no prohibition in the related proprietary lease against pledging such shares or assigning the proprietary lease that has been violated in connection with the origination of the Cooperative Loan.

(xli)

With respect to each Cooperative Loan, as of the closing of such Cooperative Loan, the originator of the Cooperative Loan obtained evidence that, if the Cooperative Property is in a federally designated flood area, a flood insurance policy has been obtained in an amount equal to at least that required by applicable law, which insurance the Cooperative Corporation is obligated to maintain at the Cooperative Corporation's cost and expense.

(xlii)

With respect to each Cooperative Loan, as of the Closing Date, such Cooperative Loan is secured by shares held by a "tenant-stockholder" of a corporation that qualifies as a "cooperative housing corporation" as such terms are defined in Section 216(b)(1) of the Code and to the best of the Seller's knowledge, no Cooperative Corporation is subject to proceedings which would, if adversely determined, result in such Cooperative Corporation losing its status as a "cooperative housing corporation" under Section 216(b)(1) of the Code.

(xliii)

With respect to each Cooperative Loan, the related Mortgage and related UCC financing statement creates a first-priority security interest in the stock in the Cooperative Corporation and the related proprietary lease of the related Cooperative Unit which were pledged to secure such Cooperative Loan, and the Cooperative Corporation owns the Cooperative Corporation as an estate in fee simple in real property or pursuant to a leasehold acceptable to ▇▇▇▇▇▇ Mae.
