Corp., as purchaser (the "Purchaser"), and Natixis Real Estate Capital Inc.

("Natixis RE") and Natixis Commercial Mortgage Funding, LLC ("Natixis CMF"), as

sellers (each, a "Seller" and collectively, "Sellers").

Capitalized terms used in this Agreement not defined herein shall

have the meanings ascribed to them in the Pooling and Servicing Agreement dated

as of July 1, 2007 (the "Pooling and Servicing Agreement") among the Purchaser,

as depositor (the "Depositor"), Wachovia Bank, National Association, as master

servicer (the "Master Servicer"), CWCapital Asset Management LLC, as special

servicer (the "Special Servicer") and LaSalle Bank National Association, as

trustee (the "Trustee"), pursuant to which the Purchaser will sell the Mortgage

Loans (as defined herein) to a trust fund and certificates representing

ownership interests in the Mortgage Loans will be issued by the trust fund. For

purposes of this Agreement, the term "Natixis RE Mortgage Loans" refers to the

mortgage loans listed on Exhibit A-1, the term "Natixis CMF Mortgage Loans"

refers to the mortgage loans listed on Exhibit A-2, the term "Mortgage Loans"

refers to the Natixis RE Mortgage Loans and the Natixis CMF Mortgage Loans,

collectively, and the term "Mortgaged Properties" refers to the properties

securing such Mortgage Loans.

The Purchaser and the Sellers wish to prescribe the manner of sale

of the Natixis RE Mortgage Loans from Natixis RE to the Purchaser and the sale

of the Natixis CMF Mortgage Loans from Natixis CMF to the Purchaser and in

consideration of the premises and the mutual agreements hereinafter set forth,

agree as follows:

SECTION 1. Sale and Conveyance of Mortgages; Possession of Mortgage

File. Effective as of the Closing Date and upon receipt of the purchase price

set forth in the immediately succeeding paragraph, each of Natixis RE and

Natixis CMF does hereby sell, transfer, assign, set over and convey to the

Purchaser, without recourse (subject to certain agreements regarding servicing

as provided in the Pooling and Servicing Agreement, subservicing agreements

permitted thereunder and that certain Servicing Rights Purchase Agreement, dated

as of the Closing Date between the Master Servicer and the Sellers) all of its

right, title, and interest in and to the Natixis RE Mortgage Loans, in the case

of Natixis RE, and the Natixis CMF Mortgage Loans, in the case of Natixis CMF,

including all interest and principal received on or with respect to such

Mortgage Loans after the Cut-off Date (other than payments of principal and

interest first due on such Mortgage Loans on or before the Cut-off Date). Upon

the sale of the Mortgage Loans, the ownership of each related Mortgage Note, the

Mortgage and the other contents of the related Mortgage File will be vested in

the Purchaser and immediately thereafter the Trustee and the ownership of

records and documents with respect to the related Mortgage Loan prepared by or

which come into the possession of each Seller (other than the records and

documents described in the proviso to Section 3(a) hereof) shall immediately

vest in the Purchaser and immediately thereafter the Trustee. Each Seller's

records will accurately reflect the sale of each such Mortgage Loan to the

Purchaser. The Depositor will sell the Class A-1, Class A-2, Class A-2FL, Class

A-3, Class A-4, Class A-SB, Class A-1A, Class X, Class A-M, Class A-J, Class B,

Class C, Class D, Class E and Class F Certificates (the "Offered Certificates")

to the underwriters (the "Underwriters") specified in the underwriting agreement

dated June 28, 2007 (the "Underwriting Agreement") between the Depositor and

J.P. Morgan Securities Inc. ("JPMSI") for itself and as representative of the

several underwriters identified therein, and the Depositor will sell the Class

G, Class H, Class J, Class K, Class L, Class M, Class N, Class P, Class Q, Class

T and Class NR Certificates (the "Private Certificates") to JPMSI and UBS

Securities LLC, the initial purchasers (together with the Underwriters, the

"Dealers") specified in the certificate purchase agreement dated June 28, 2007

(the "Certificate Purchase Agreement"), between the Depositor and JPMSI for

itself and as representative of the initial purchasers identified therein.

The sale and conveyance of the Mortgage Loans is being conducted on

an arms length basis and upon commercially reasonable terms. As the purchase

price for the Natixis RE Mortgage Loans and the Natixis CMF Mortgage Loans, the

Purchaser shall pay to Natixis RE or at Natixis RE's direction in immediately

available funds the sum of $670,683,086.52 (which amount is inclusive of accrued

interest and exclusive of Natixis RE's and Natixis CMF's pro rata share of the

costs set forth in Section 9 hereof). The purchase and sale of the Mortgage

Loans shall take place on the Closing Date.

SECTION 2. Books and Records; Certain Funds Received After the

Cut-off Date. From and after the sale of the Mortgage Loans to the Purchaser,

record title to each Mortgage and the related Mortgage Note shall be transferred

to the Trustee in accordance with this Agreement. Any funds due after the

Cut-off Date in connection with a Mortgage Loan received by a Seller shall be

held in trust for the benefit of the Trustee as the owner of such Mortgage Loan

and shall be transferred promptly to the Master Servicer. All scheduled payments

of principal and interest due on or before the Cut-off Date but collected after

the Cut-off Date, and recoveries of principal and interest collected on or

before the Cut-off Date (only in respect of principal and interest on the

Mortgage Loans due on or before the Cut-off Date and principal prepayments

thereon), shall belong to, and shall be promptly remitted to, the applicable

Seller.

The transfer of each Mortgage Loan shall be reflected on the

applicable Seller's balance sheets and other financial statements as a sale of

such Mortgage Loan by the applicable Seller to the Purchaser. Each Seller

intends to treat the transfer of each Mortgage Loan to the Purchaser as a sale

for tax purposes.

The transfer of each Mortgage Loan shall be reflected on the

Purchaser's balance sheets and other financial statements as a purchase of such

Mortgage Loan by the Purchaser from the applicable Seller. The Purchaser intends

to treat the transfer of each Mortgage Loan from the applicable Seller as a

purchase for tax purposes.

SECTION 3. Delivery of Mortgage Loan Documents; Additional Costs and

Expenses. (a) The Purchaser hereby directs each Seller, and each Seller hereby

agrees, upon the transfer of the Mortgage Loans contemplated herein, to deliver

on the Closing Date to the Trustee or a Custodian appointed thereby, all

documents, instruments and agreements required to be delivered by the Purchaser

to the Trustee with respect to the applicable Mortgage Loans under Sections

2.01(b) and 2.01(c) of the Pooling and Servicing Agreement, and meeting all the

requirements of such Sections 2.01(b) and 2.01(c), and such other documents,

instruments and agreements as the Purchaser or the Trustee shall reasonably

request. In addition, each Seller agrees to deliver or cause to be delivered to

the Master Servicer, the Servicing File for each Mortgage Loan transferred

pursuant to this Agreement; provided that neither Seller shall be required to

deliver any draft documents, or any attorney client communications which are

privileged communications or constitute legal or other due diligence analyses,

or internal communications of such Seller or its affiliates, or credit

underwriting or other analyses or data.

(b) With respect to the transfer described in Section 1 hereof, if

the Mortgage Loan documents do not require the related Mortgagor to pay any

costs and expenses relating to any modifications to a related letter of credit

which modifications are required to effectuate such transfer (the "Transfer

Modification Costs"), then the applicable Seller shall pay the Transfer

Modification Costs required to transfer the letter of credit to the Trustee as

described in such Section 1; provided that if the Mortgage Loan documents

require the related Mortgagor to pay any Transfer Modification Costs, such

Transfer Modification Costs shall be an expense of the Mortgagor unless such

Mortgagor fails to pay such Transfer Modification Costs after the Master

Servicer has exercised all remedies available under the Mortgage Loan documents

to collect such Transfer Modification Costs from such Mortgagor, in which case

the Master Servicer shall give the applicable Seller notice of such failure and

the amount of such Transfer Modification costs and the applicable Seller shall

pay such Transfer Modification Costs.

SECTION 4. Treatment as a Security Agreement. Each Seller,

concurrently with the execution and delivery hereof, has conveyed to the

Purchaser, all of its right, title and interest in and to the applicable

Mortgage Loans. The parties intend that such conveyance of each Seller's right,

title and interest in and to the applicable Mortgage Loans pursuant to this

Agreement shall constitute a purchase and sale and not a loan. If such

conveyance is deemed to be a pledge and not a sale, then the parties also intend

and agree that the applicable Seller shall be deemed to have granted, and in

such event does hereby grant, to the Purchaser, a first priority security

interest in all of its right, title and interest in, to and under the applicable

Mortgage Loans, all payments of principal or interest on such Mortgage Loans due

after the Cut-off Date, all other payments made in respect of such Mortgage

Loans after the Cut-off Date (except to the extent such payments were due on or

before the Cut-off Date) and all proceeds thereof and that this Agreement shall

constitute a security agreement under applicable law. If such conveyance is

deemed to be a pledge and not a sale, the applicable Seller consents to the

Purchaser hypothecating and transferring such security interest in favor of the

Trustee and transferring the obligation secured thereby to the Trustee.

SECTION 5. Covenants of the Sellers. Each Seller covenants with the

Purchaser as follows:

(a) it shall record or cause a third party to record in the

appropriate public recording office for real property the intermediate

assignments of the applicable Mortgage Loans and the Assignments of Mortgage

from such Seller to the Trustee in connection with the Pooling and Servicing

Agreement; provided, if the related Mortgage has been recorded in the name of

Mortgage Electronic Registration Systems, Inc. ("MERS") or its designee, no

assignment of Mortgage Loans, Assignment of Mortgage or other recorded document

in favor of the Trustee will be required to be prepared or delivered and

instead, such Seller shall take all actions as are necessary to cause the

Trustee to be shown as, and shall deliver evidence of any such transfers to the

Master Servicer and the Special Servicer, and the Trustee shall take all actions

necessary to confirm that it is shown as, the owner of the related Mortgage on

the records of MERS for purposes of the system of recording transfers of

beneficial ownership of mortgages maintained by MERS. All recording fees

relating to the initial recordation of such intermediate assignments and

Assignments of Mortgage shall be paid by such Seller;

(b) it shall take any action reasonably required by the Purchaser,

the Trustee or the Master Servicer, in order to assist and facilitate in the

transfer of the servicing of the applicable Mortgage Loans to the Master

Servicer, including effectuating the transfer of any letters of credit with

respect to any applicable Mortgage Loan to the Trustee (in care of the Master

Servicer) for the benefit of Certificateholders. Prior to the date that a letter

of credit, if any, with respect to any applicable Mortgage Loan is transferred

to the Trustee (in care of the Master Servicer), such Seller will cooperate with

the reasonable requests of the Master Servicer or Special Servicer, as

applicable, in connection with effectuating a draw under such letter of credit

as required under the terms of the related Mortgage Loan documents;

(c) if, during such period of time after the first date of the

public offering of the Offered Certificates as in the opinion of counsel for the

Underwriters, a prospectus relating to the Offered Certificates is required by

applicable law to be delivered in connection with sales thereof by an

Underwriter or a Dealer, any event shall occur as a result of which it is

necessary to amend or supplement the Prospectus Supplement, including Annexes

A-1, A-2, A-3 and B thereto and the Diskette included therewith, with respect to

any information relating to the Mortgage Loans or such Seller, in order to make

the statements therein, in the light of the circumstances when the Prospectus

Supplement is delivered to a purchaser, not misleading, or if it is necessary to

amend or supplement the Prospectus Supplement, including Annexes A-1, A-2, A-3

and B thereto and the Diskette included therewith, with respect to any

information relating to the applicable Mortgage Loans or such Seller, to comply

with applicable law, such Seller (or in the case of Natixis CMF, Natixis RE on

behalf of such Seller) shall do all things necessary to assist the Depositor to

prepare and furnish, at the expense of such Seller (to the extent that such

amendment or supplement relates to such Seller, the Mortgage Loans listed on

Exhibit A-1, or Exhibit A-2, as applicable, and/or any information relating to

the same, as provided by such Seller), to the Underwriters such amendments or

supplements to the Prospectus Supplement as may be necessary, so that the

statements in the Prospectus Supplement as so amended or supplemented, including

Annexes A-1, A-2, A-3 and B thereto and the Diskette included therewith, with

respect to any information relating to the applicable Mortgage Loans or such

Seller, will not, in the light of the circumstances when the Prospectus is so

amended or supplemented, be misleading or so that the Prospectus Supplement,

including Annexes A-1, A-2, A-3 and B thereto and the Diskette included

therewith, with respect to any information relating to the applicable Mortgage

Loans or such Seller, will comply with applicable law. All terms used in this

clause (c) and not otherwise defined herein shall have the meaning set forth in

the Indemnification Agreement, dated as of June 28, 2007 between the Purchaser

and Natixis RE (the "Indemnification Agreement"); and

(d) for so long as the Trust is subject to the reporting

requirements of the Exchange Act, such Seller (or in the case of Natixis CMF,

Natixis RE on behalf of such Seller) shall provide the Purchaser (or with

respect to any Companion Loan related to a Serviced Whole Loan or any Serviced

Securitized Companion Loan that is deposited into an Other Securitization or a

Regulation AB Companion Loan Securitization, the depositor in such Other

Securitization or Regulation AB Companion Loan Securitization) and the Trustee

with any Additional Form 10-D Disclosure and any Additional Form 10-K Disclosure

set forth next to the Purchaser's name on Schedule X and Schedule Y of the

Pooling and Servicing Agreement within the time periods set forth in the Pooling

and Servicing Agreement.

(c) Natixis RE further makes the representations and warranties as

to the Natixis RE Mortgage Loans and the Natixis CMF Mortgage Loans set forth in

Exhibit B as of the Closing Date (or as of such other date if specifically

provided in the particular representation or warranty), which representations

and warranties are subject to the exceptions thereto set forth in Exhibit C.

Neither the delivery by the Sellers of the Mortgage Files, Servicing Files, or

any other documents required to be delivered under Section 2.01 of the Pooling

and Servicing Agreement, nor the review thereof or any other due diligence by

the Trustee, any Master Servicer, the Special Servicer, a Certificate Owner or

any other Person shall relieve a Seller of any liability or obligation with

respect to any representation or warranty or otherwise under this Agreement or

constitute notice to any Person of a Breach or Defect (it being understood that

only Natixis RE shall be liable with respect to any representation or warranty

set forth on Exhibit B with respect to the Mortgage Loans (including the Natixis

CMF Mortgage Loans)).

(d) Pursuant to this Agreement or Section 2.03(b) of the Pooling and

Servicing Agreement, the Sellers and the Purchaser shall be given notice of any

Breach or Defect that materially and adversely affects the value of any Mortgage

Loan, the value of the related Mortgaged Property or the interests of the

Trustee or any Certificateholder therein.

(e) Upon notice pursuant to Section 6(d) above, Natixis RE shall,

not later than 90 days from the earlier of a Seller's receipt of the notice or,

in the case of a Defect or Breach relating to a Mortgage Loan not being a

"qualified mortgage" within the meaning of Section 860G(a)(3) of the Code, but

without regard to the rule of Treasury Regulation Section 1.860G-2(f)(2) that

causes a defective mortgage loan to be treated as a qualified mortgage, a

Seller's discovery of such Breach or Defect (the "Initial Resolution Period"),

(i) cure such Defect or Breach, as the case may be, in all material respects,

(ii) repurchase the affected Mortgage Loan at the applicable Repurchase Price

(as defined below) or (iii) substitute a Qualified Substitute Mortgage Loan (as

defined below) for such affected Mortgage Loan (provided that in no event shall

any such substitution occur later than the second anniversary of the Closing

Date) and pay the Master Servicer for deposit into the Certificate Account, any

Substitution Shortfall Amount (as defined below) in connection therewith;

provided, however, except with respect to a Defect resulting solely from the

failure by a Seller to deliver to the Trustee or Custodian the actual policy of

lender's title insurance required pursuant to clause (ix) of the definition of

Mortgage File by a date not later than 18 months following the Closing Date, if

such Breach or Defect is capable of being cured but is not cured within the

Initial Resolution Period, and Natixis RE has commenced and is diligently

proceeding with the cure of such Breach or Defect within the Initial Resolution

Period, Natixis RE shall have an additional 90 days commencing immediately upon

the expiration of the Initial Resolution Period (the "Extended Resolution

Period") to complete such cure (or, failing such cure, to repurchase the related

Mortgage Loan or substitute a Qualified Substitute Mortgage Loan as described

above); and provided, further, with respect to the Extended Resolution Period

Natixis RE shall have delivered an officer's certificate to the Rating Agencies,

the Master Servicer, the Special Servicer, the Trustee and the Directing

Certificateholder setting forth the reason such Breach or Defect is not capable

of being cured within the Initial Resolution Period and what actions Natixis RE

is pursuing in connection with the cure thereof and stating that Natixis RE

anticipates that such Breach or Defect will be cured within the Extended

Resolution Period. Notwithstanding the foregoing, any Defect or Breach which

causes any Mortgage Loan not to be a "qualified mortgage" (within the meaning of

Section 860G(a)(3) of the Code, without regard to the rule of Treasury

Regulations Section 1.860G-2(f)(2) which causes a defective mortgage loan to be

treated as a qualified mortgage) shall be deemed to materially and adversely

affect the interests of the holders of the Certificates therein, and such

Mortgage Loan shall be repurchased or a Qualified Substitute Mortgage Loan

substituted in lieu thereof without regard to the extended cure period described

in the preceding sentence. If the affected Mortgage Loan is to be repurchased,

Natixis RE shall remit the Repurchase Price (defined below) in immediately

available funds to the Trustee.

If any Breach pertains to a representation or warranty that the

related Mortgage Loan documents or any particular Mortgage Loan document

requires the related Mortgagor to bear the costs and expenses associated with

any particular action or matter under such Mortgage Loan document(s), then

Natixis RE shall cure such Breach within the applicable cure period (as the same

may be extended) by reimbursing the Trust Fund (by wire transfer of immediately

available funds) the reasonable amount of any such costs and expenses incurred

by the Master Servicer, the Special Servicer, the Trustee or the Trust Fund that

are the basis of such Breach and have not been reimbursed by the related

Mortgagor; provided, however, in the event any such costs and expenses exceed

$10,000, Natixis RE shall have the option to either repurchase or substitute for

the related Mortgage Loan as provided above or pay such costs and expenses.

Except as provided in the proviso to the immediately preceding sentence, Natixis

RE shall remit the amount of such costs and expenses and upon its making such

remittance, Natixis RE shall be deemed to have cured such Breach in all

respects. To the extent any fees or expenses that are the subject of a cure by

Natixis RE are subsequently obtained from the related Mortgagor, the portion of

the cure payment equal to such fees or expenses obtained from the Mortgagor

shall be returned to Natixis RE pursuant to Section 2.03(f) of the Pooling and

Servicing Agreement. Notwithstanding the foregoing, the sole remedy with respect

to any breach of the representation set forth in the second to last sentence of

clause (32) of Exhibit B hereto shall be payment by Natixis RE of such costs and

expenses without respect to the materiality of such breach.

Any of the following will cause a document in the Mortgage File to

be deemed to have a Defect and to be conclusively presumed to materially and

adversely affect the interests of Certificateholders in a Mortgage Loan and to

be deemed to materially and adversely affect the interests of the

Certificateholders in and the value of a Mortgage Loan: (a) the absence from the

Mortgage File of the original signed Mortgage Note, unless the Mortgage File

contains a signed lost note affidavit and indemnity with a copy of the Mortgage

Note that appears to be regular on its face; (b) the absence from the Mortgage

File of the original signed Mortgage that appears to be regular on its face,

unless there is included in the Mortgage File a certified copy of the Mortgage

and a certificate stating that the original signed Mortgage was sent for

recordation; (c) the absence from the Mortgage File of the lender's title

insurance policy (or if the policy has not yet been issued, an original or copy

of a "marked up" written commitment or the pro-forma or specimen title insurance

policy or a commitment to issue the same pursuant to written escrow instructions

signed by the title insurance company) called for by clause (ix) of the

definition of "Mortgage File" in the Pooling and Servicing Agreement; (d) the

absence from the Mortgage File of any required letter of credit; (e) with

respect to any leasehold mortgage loan, the absence from the related Mortgage

File of a copy (or an original, if available) of the related Ground Lease; or

(f) the absence from the Mortgage File of any intervening assignments required

to create a complete chain of assignments to the Trustee on behalf of the Trust,

unless there is included in the Mortgage File a certified copy of the

intervening assignment and a certificate stating that the original intervening

assignments were sent for recordation; provided, however, no Defect (except the

Defects previously described in clauses (a) through (f)) shall be considered to

materially and adversely affect the value of any Mortgage Loan, the value of the

related Mortgaged Property, or the interests of the Trustee therein or the

interests of any Certificateholder therein unless the document with respect to

which the Defect exists is required in connection with an imminent enforcement

of the Mortgagee's rights or remedies under the related Mortgage Loan, defending

any claim asserted by any borrower or third party with respect to the Mortgage

Loan, establishing the validity or priority of any lien on any collateral

securing the Mortgage Loan or for any immediate significant servicing

obligation. Notwithstanding the foregoing, the delivery of executed escrow

instructions or a commitment to issue a lender's title insurance policy, as

provided in clause (ix) of the definition of "Mortgage File" in the Pooling and

Servicing Agreement, in lieu of the delivery of the actual policy of lender's

title insurance, shall not be considered a Defect or Breach with respect to any

Mortgage File if such actual policy is delivered to the Trustee or its Custodian

within 18 months after the Closing Date.

If (i) any Mortgage Loan is required to be repurchased or

substituted for in the manner described in the first paragraph of this Section

6(e), (ii) such Mortgage Loan is a Crossed Loan, and (iii) the applicable Defect

or Breach does not constitute a Defect or Breach, as the case may be, as to any

other Crossed Loan in such Crossed Group (without regard to this paragraph),

then the applicable Defect or Breach, as the case may be, will be deemed to

constitute a Defect or Breach, as the case may be, as to each other Crossed Loan

in the Crossed Group for purposes of this paragraph, and Natixis RE will be

required to repurchase or substitute for all of the remaining Crossed Loans in

the related Crossed Group as provided in the first paragraph of this Section

6(e) unless such other Crossed Loans in such Crossed Group satisfy the Crossed

Loan Repurchase Criteria, and the Mortgage Loan affected by the applicable

Defect or Breach and the Qualified Substitute Mortgage Loan, if any, satisfy all

other criteria for repurchase or substitution, as applicable, of Mortgage Loans

set forth herein. In the event that the remaining Crossed Loans satisfy the

aforementioned criteria, Natixis RE may elect either to repurchase or substitute

for only the affected Crossed Loan as to which the related Breach or Defect

exists or to repurchase or substitute for all of the Crossed Loans in the

related Crossed Group. Natixis RE shall be responsible for the cost of any

Appraisal required to be obtained by the Master Servicer to determine if the

Crossed Loan Repurchase Criteria have been satisfied, so long as the scope and

cost of such Appraisal has been approved by Natixis RE (such approval not to be

unreasonably withheld).

To the extent that Natixis RE is required to repurchase or

substitute for a Crossed Loan hereunder in the manner prescribed above while the

Trustee continues to hold any other Crossed Loans in such Crossed Group, neither

Natixis RE nor the Trustee shall enforce any remedies against the other's

Primary Collateral, but each is permitted to exercise remedies against the

Primary Collateral securing its respective Crossed Loans, including with respect

to the Trustee, the Primary Collateral securing Crossed Loans still held by the

Trustee.

If the exercise of remedies by one party would materially impair the

ability of the other party to exercise its remedies with respect to the Primary

Collateral securing the Crossed Loans held by such party, then Natixis RE and

the Trustee shall forbear from exercising such remedies until the Mortgage Loan

documents evidencing and securing the relevant Crossed Loans can be modified in

a manner that removes the threat of material impairment as a result of the

exercise of remedies or some other accommodation can be reached. Any reserve or

other cash collateral or letters of credit securing the Crossed Loans shall be

allocated between such Crossed Loans in accordance with the Mortgage Loan

documents, or otherwise on a pro rata basis based upon their outstanding Stated

Principal Balances. Notwithstanding the foregoing, if a Crossed Loan that

remains in the Trust Fund is modified to terminate the related cross

collateralization and/or cross default provisions, as a condition to such

modification, Natixis RE shall furnish to the Trustee an Opinion of Counsel that

any modification shall not cause an Adverse REMIC Event. Any expenses incurred

by the Purchaser in connection with such modification or accommodation

(including but not limited to recoverable attorney fees) shall be paid by

Natixis RE.

The "Repurchase Price" with respect to any Mortgage Loan or REO Loan

to be repurchased pursuant to this Agreement and Section 2.03 of the Pooling and

Servicing Agreement, shall have the meaning given to the term "Purchase Price"

in the Pooling and Servicing Agreement.

A "Qualified Substitute Mortgage Loan" with respect to any Mortgage

Loan or REO Loan to be substituted pursuant to this Agreement and Section 2.03

of the Pooling and Servicing Agreement, shall have the meaning given to such

term in the Pooling and Servicing Agreement.

A "Substitution Shortfall Amount" with respect to any Mortgage Loan

or REO Loan to be substituted pursuant to this Agreement and Section 2.03 of the

Pooling and Servicing Agreement, shall have the meaning given to such term in

the Pooling and Servicing Agreement.

In connection with any repurchase or substitution of one or more

Mortgage Loans contemplated hereby, (i) the Purchaser shall execute and deliver,

or cause the execution and delivery of, such endorsements and assignments,

without recourse, as shall be necessary to vest in Natixis RE the legal and

beneficial ownership of each repurchased Mortgage Loan or replaced Mortgage

Loan, as applicable, (ii) the Purchaser shall deliver, or cause the delivery, to

Natixis RE of all portions of the Mortgage File and other documents (including

the Servicing File) pertaining to such Mortgage Loan possessed by the Trustee,

or on the Trustee's behalf, and (iii) the Purchaser shall release, or cause to

be released, to Natixis RE any escrow payments and reserve funds held by the

Trustee, or on the Trustee's behalf, in respect of such repurchased or replaced

Mortgage Loans.

(f) The representations and warranties of the parties hereto shall

survive the execution and delivery and any termination of this Agreement and

shall inure to the benefit of the respective parties, notwithstanding any

restrictive or qualified endorsement on the Mortgage Notes or Assignment of

Mortgage or the examination of the Mortgage Files.

(g) Each party hereby agrees to promptly notify the other party of

any Breach of a representation or warranty contained in this Section 6. Natixis

RE's obligation to cure any Breach or Defect or repurchase or substitute for the

affected Mortgage Loan pursuant to Section 6(e) herein shall constitute the sole

remedy available to the Purchaser in connection with a Breach or Defect (subject

to the last sentence of the second paragraph of Section 6(e)). It is

acknowledged and agreed that the representations and warranties are being made

for risk allocation purposes only; provided, however, no limitation of remedy is

implied with respect to Natixis RE's breach of its obligation to cure,

repurchase or substitute in accordance with the terms and conditions of this

Agreement.
