subject to the following: (i) if the aggregate distribution to the Class A

Certificates on any Distribution Date of the Class A Prepayment Percentage

provided above of Unscheduled Principal Receipts distributable on such

Distribution Date would reduce the Class A Principal Balance below zero, the

Class A Prepayment Percentage for such Distribution Date shall be the percentage

necessary to bring the Class A Principal Balance to zero and thereafter the

Class A Prepayment Percentage shall be zero and (ii) if the Class A Percentage

as of any Distribution Date is greater than the Original Class A Percentage, the

Class A Prepayment Percentage for such Distribution Date shall be 100%.

Notwithstanding the foregoing, with respect to any Distribution Date on which

the following criteria are not met, the reduction of the Class A Prepayment

Percentage described in the second through sixth sentences of this definition of

Class A Prepayment Percentage shall not be applicable with respect to such

Distribution Date. In such event, the Class A Prepayment Percentage for such

Distribution Date will be determined in accordance with the applicable

provision, as set forth in the first through fifth sentences above, which was

actually used to determine the Class A Prepayment Percentage for the

Distribution Date occurring in the March preceding such Distribution Date (it

being understood that for the purposes of the determination of the Class A

Prepayment Percentage for the current Distribution Date, the current Class A

Percentage and Subordinated Percentage shall be utilized). In addition, if on

any Distribution Date, prior to giving effect to any distributions on such

Distribution Date, (i) the Subordinated Percentage is equal to or greater than

twice the Subordinated Percentage as of the Cut-Off Date, (ii) the average

outstanding principal balance on such Distribution Date and for the preceding

five Distribution Dates of the Mortgage Loans that were delinquent 60 days or

more (including for this purpose any Mortgage Loans in foreclosure and Mortgage

Loans with respect to which the related Mortgaged Property has been acquired by

the Trust Estate) does not exceed 50% of the Class B Principal Balance and

(iii)(A) prior to the Distribution Date in April 2008, cumulative Realized

Losses on the Mortgage Loans do not exceed 20% of the Original Class B Principal

Balance, then the Class A Prepayment Percentage for such Distribution Date will

equal the Class A Percentage for such Distribution Date plus 50% of the

Subordinated Percentage for such Distribution Date or (B) on or after the

Distribution Date in April 2008, cumulative Realized Losses on the Mortgage

Loans do not exceed 30% of the Original Class B Principal Balance, then the

Class A Prepayment Percentage for such Distribution Date will equal the Class A

Percentage for such Distribution Date. No reduction in the Class A Prepayment

Percentage referred to in the second through sixth sentences hereof shall be

applicable, with respect to any Distribution Date if (a) the average outstanding

principal balance on such Distribution Date and for the preceding five

Distribution Dates on the Mortgage Loans that were delinquent 60 days or more

(including for this purpose any payments due with respect to Mortgage Loans in

foreclosure and REO Mortgage Loans) were greater than or equal to 50% of the

current Class B Principal Balance or (b) cumulative Realized Losses on the

Mortgage Loans exceed (1) 30% of the Original Class B Principal Balance if such

Distribution Date occurs between and including April 2010 and March 2011, (2)

35% of the Original Class B Principal Balance if such Distribution Date occurs

between and including April 2011 and March 2012, (3) 40% of the Original Class B

Principal Balance if such Distribution Date occurs between and including April

2012 and March 2013, (4) 45% of the Original Class B Principal Balance if such

Distribution Date occurs between and including April 2013 and March 2014, and

(5) 50% of the Original Class B Principal Balance, if such Distribution Date

occurs during or after April 2014. With respect to any Distribution Date on

which the Class A Prepayment Percentage is reduced below the Class A Prepayment

insurance policy in the jurisdiction in which the related mortgage

property is located.

(c) If any assignment of a Mortgage to the Trustee is in the process

of being recorded on the Closing Date, the Seller shall use its best efforts to

cause each such original recorded document or certified copy thereof to be

delivered to the Custodian promptly following its recordation, but in no event

later than one (1) year following the Closing Date. If any Mortgage has been

recorded in the name of MERS or its designee, no assignment of Mortgage in favor

of the Trustee will be required to be prepared or delivered and instead, the

Master Servicer shall take all actions as are necessary to cause the Trust

Estate to be shown as the owner of the related Mortgage Loan on the records of

MERS for the purpose of the system of recording transfers of beneficial

ownership of mortgages maintained by MERS. The Seller shall also cause to be

delivered to the Custodian any other original mortgage loan document included in

the Owner Mortgage Loan File if a copy thereof has been delivered. The Seller

shall pay from its own funds, without any right of reimbursement therefor, the

amount of any costs, liabilities and expenses incurred by the Trust Estate by

reason of the failure of the Seller to cause to be delivered to the Custodian

within one (1) year following the Closing Date any assignment of a Mortgage

(except with respect to any Mortgage recorded in the name of MERS) not delivered

to the Custodian on the Closing Date.

In lieu of recording an assignment of any Mortgage the Seller may,

deliver or cause to be delivered to the Custodian the assignment of the Mortgage

Loan to the Trustee in a form suitable for recordation, if (i) with respect to a

particular state the Trustee has received an Opinion of Counsel acceptable to it

that such recording is not required to make the assignment effective against the

parties to the Mortgage or subsequent purchasers or encumbrances of the

Mortgaged Property or (ii) the Seller has been advised by each Rating Agency

that non-recordation in a state will not result in a reduction of the rating

assigned by that Rating Agency at the time of initial issuance of the

Certificates. Set forth on Exhibit K attached hereto is a list of all states

where recordation is required by either Rating Agency to obtain the initial

ratings of the Certificates. The Custodian may rely and shall be protected in

relying upon the information contained in such Exhibit K. In the event that the

Custodian receives notice that recording is required to protect the right, title

and interest of the Trustee in and to any such Mortgage Loan for which

recordation of an assignment has not previously been required, the Custodian

shall promptly notify the Trustee and the Custodian shall within five Business

Days (or such other reasonable period of time mutually agreed upon by the

Custodian and the Trustee) of its receipt of such notice deliver each previously

unrecorded assignment to the related Servicer for recordation.

(d) Except for Mortgage Notes endorsed in blank, endorsements shall

comply with the following:

WACHOVIA BANK, NATIONAL ASSOCIATION, AS

TRUSTEE

and its successors and assigns

Section 2.02 Acceptance by Custodian.

Subject to the provisions of the following paragraph, pursuant to

the Custodial Agreement, the Custodian, on behalf of the Trustee, will declare

that it holds and will hold the documents delivered to it pursuant to Section

2.01(a) above and the other documents constituting a part of the Owner Mortgage

Loan Files or Retained Mortgage Loan Files (after the occurrence of a Document

Transfer Event) delivered to it in trust, upon the trusts herein set forth, for

the use and benefit of all present and future Certificateholders. Upon execution

of this Agreement, the Custodian will deliver to the Seller and the Trustee an

initial certification in the form of Exhibit N hereto, to the effect that,

except as may be specified in a list of exceptions attached thereto, it has

received the original Mortgage Notes relating to each Mortgage Loan on the

Mortgage Loan Schedule.

The Custodian will review each Owner Mortgage Loan File within 45

days after execution of this Agreement. The Custodian will deliver no later than

30 days after completion of such review to the Seller and the Trustee a final

certification in the form of Exhibit O hereto to the effect that, except as may

be specified in a list of exceptions attached thereto, all required documents

set forth in Section 2.01(a) have been executed and received and appear regular

on their face, and that such documents relate to the Mortgage Loans identified

in the Mortgage Loan Schedule based on a comparison of the Mortgage Loan

identifying number, Mortgagor name and street address, and in so doing the

Custodian may rely on the purported due execution and genuineness of any such

document and on the purported genuineness of any signature thereon.

If within such 45 day period the Custodian finds any document

constituting a part of an Owner Mortgage Loan File not to have been executed or

received or to be unrelated to the Mortgage Loans identified in the Mortgage

Loan Schedule or not to appear regular on its face, the Custodian shall promptly

(and in no event more than 30 days after completion of the review) notify the

Trustee and the Trustee shall notify the Seller. The Seller shall have a period

of 60 days after the date of such notice within which to correct or cure any

such defect. The Seller hereby covenants and agrees that, if any material defect

is not so corrected or cured, the Seller will, not later than 60 days after the

Trustee's notice to it referred to above respecting such defect, either (i)

repurchase the related Mortgage Loan or any property acquired in respect thereof

from the Trust Estate at a price equal to (a) 100% of the unpaid principal

balance of such Mortgage Loan plus (b) accrued interest at the Mortgage Interest

Rate through the last day of the month in which such repurchase takes place or

(ii) if within two years of the Startup Day, or such other period permitted by

the REMIC Provisions, substitute for any Mortgage Loan to which such material

defect relates, a new mortgage loan (a "Substitute Mortgage Loan") having such

characteristics so that the representations and warranties of the Seller set

forth in Section 2.03(b) hereof (other than Section 2.03(b)(i)) would not have

been incorrect had such Substitute Mortgage Loan originally been a Mortgage

Loan. In no event shall any Substitute Mortgage Loan have an unpaid principal

balance, as of the date of substitution, greater than the Scheduled Principal

Balance (reduced by the scheduled payment of principal due on the Due Date in

the month of substitution) of the Mortgage Loan for which it is substituted. In

addition, such Substitute Mortgage Loan (i) shall have a Loan-to-Value Ratio

less than or equal to and a Net Mortgage Interest Rate equal to that of the

Mortgage Loan for which it is substituted, (ii) shall have the same Gross Margin

and Index as that of the Mortgage Loan for which it is substituted and (iii)

shall have the same frequency of mortgage rate adjustment as that of the

Mortgage Loan for which it is substituted.

In the case of a repurchased Mortgage Loan or property, the purchase

price shall be deposited by the Seller in the Certificate Account maintained by

the Master Servicer pursuant to Section 3.01. In the case of a Substitute

Mortgage Loan, the Owner Mortgage Loan File (and Retained Mortgage Loan File, if

required pursuant to Section 2.01(b) hereof) relating thereto shall be delivered

to the Custodian and the Substitution Principal Amount, together with (i)

interest on such Substitution Principal Amount at the applicable Net Mortgage

Interest Rate to the following Due Date of such Mortgage Loan which is being

substituted for and (ii) an amount equal to the aggregate amount of unreimbursed

Periodic Advances in respect of interest previously made by the Servicer, the

Master Servicer or the Trustee with respect to such Mortgage Loan, shall be

deposited in the Certificate Account. The Monthly Payment on the Substitute

Mortgage Loan for the Due Date in the month of substitution shall not be part of

the Trust Estate. Upon receipt by the Custodian of a Request for Release signed

by an officer of the Seller, the Custodian shall release to the Seller the

related Owner Mortgage Loan File (and Retained Mortgage Loan File, if

applicable). The Trustee shall execute and deliver such instrument of transfer

or assignment (or, in the case of a Mortgage Loan registered in the name of MERS

or its designee, the Master Servicer shall cause the applicable Servicer to take

all necessary action to reflect such assignment on the records of MERS), in each

case without recourse, as shall be necessary to vest in the Seller legal and

beneficial ownership of such substituted or repurchased Mortgage Loan or

property. It is understood and agreed that the obligation of the Seller to

substitute a new Mortgage Loan for or repurchase any Mortgage Loan or property

as to which such a material defect in a constituent document exists shall

constitute the sole remedy respecting such defect available to the

Certificateholders or the Trustee on behalf of the Certificateholders. The

failure of the Custodian to give the final certification or the Trustee to give

any notice within the required time periods shall not affect or relieve the

Seller's obligation to repurchase any Mortgage Loan pursuant to this Section

2.02.

the Mortgage Loan or the use for which the premises were intended and to

the best of the Seller's knowledge, there is no proceeding pending or

lease, (1) the lessor under the lease holds a fee simple interest in the

land; (2) the terms of such lease expressly permit the mortgaging of the

the absence, presence or effect of hazardous wastes or hazardous substances on

any Mortgaged Property; any casualty resulting from the presence or effect of

hazardous wastes or hazardous substances on, near or emanating from any

Mortgaged Property; the impact on Certificateholders of any environmental

condition or presence of any hazardous substance on or near any Mortgaged

Property; or the compliance of any Mortgaged Property with any environmental

laws, nor is any agent, person or entity otherwise affiliated with the Seller

authorized or able to make any such representation, warranty or assumption of

liability relative to any Mortgaged Property. In addition, no representations or

warranties are made by the Seller with respect to the absence or effect of fraud

in the origination of any Mortgage Loan.

It is understood and agreed that the representations and warranties

set forth in this Section 2.03(b) shall survive delivery of the respective Owner

Mortgage Loan Files (and Retained Mortgage Loan Files, if applicable) to the

Custodian and shall inure to the benefit of the Trustee notwithstanding any

restrictive or qualified endorsement or assignment.

(c) Upon discovery by either the Seller, the Master Servicer, the

Trustee or the Custodian that any of the representations and warranties made in

subsection (b) above is not accurate (referred to herein as a "breach") and,

except for a breach of the representation and warranty set forth in subsection

(b)(i), where such breach is a result of the Cut-Off Date Principal Balance of a

Mortgage Loan being greater, by $5,000 or greater, than the Cut-Off Date

Principal Balance of such Mortgage Loan indicated on the Mortgage Loan Schedule,

that such breach materially and adversely affects the interests of the

Certificateholders in the related Mortgage Loan, the party discovering such

breach shall give prompt written notice to the other parties (any Custodian

being so obligated under a Custodial Agreement). Within 60 days of the earlier

of its discovery or its receipt of notice of any such breach the Seller shall

cure such breach in all material respects or shall either (i) repurchase the

Mortgage Loan or any property acquired in respect thereof from the Trust Estate

at a price equal to (A) 100% of the unpaid principal balance of such Mortgage

Loan plus (B) accrued interest at the Net Mortgage Interest Rate for such

Mortgage Loan through the last day of the month in which such repurchase took

place or (ii) if within two years of the Startup Day, or such other period

permitted by the REMIC Provisions, substitute for such Mortgage Loan in the

manner described in Section 2.02. In addition to the foregoing, if a breach of

the representation set forth in clause (b)(xiii) of this Section 2.03 occurs as

a result of a violation of an applicable predatory or abusive lending law, the

Seller shall reimburse the Trust for all costs and damages including, but not

limited to, reasonable attorneys' fees and costs, incurred by the Trust as a

result of the violation of such law (such amount, the "Reimbursement Amount").

The purchase price of any repurchase described in this paragraph, the

Substitution Principal Amount, if any, plus accrued interest thereon and the

other amounts referred to in Section 2.02, and any Reimbursement Amount shall be

deposited in the Certificate Account. It is understood and agreed, except with

respect to the second preceding sentence, that the obligation of the Seller to

repurchase or substitute for any Mortgage Loan or property as to which such a

breach has occurred and is continuing shall constitute the sole remedy

respecting such breach available to Certificateholders or the Trustee on behalf

of Certificateholders, and such obligation shall survive until termination of

the Trust Estate hereunder.

Section 2.04 Execution and Delivery of Certificates.

The Trustee acknowledges the assignment to it of the Mortgage Loans

and acknowledges the delivery of the Owner Mortgage Loan Files to the Custodian,

on behalf of the Trustee, and, concurrently with such delivery, has executed and

together with all other assets included in the definition of "Trust Estate,"

receipt of which is hereby acknowledged, Certificates in authorized

denominations which evidence ownership of the entire Trust Estate.

Section 2.05 Designation of Certificates; Designation of Startup Day

and Latest Possible Maturity Date.

(other than the Class A-R Certificate) and the Classes of Class B Certificates

as classes of "regular interests" and the Class A-R Certificate as the single

class of "residual interest" in the REMIC for the purposes of Code Sections

860G(a)(1) and 860G(a)(2), respectively. The Closing Date is hereby designated

as the "Startup Day" of the REMIC within the meaning of Code Section 860G(a)(9).

The "latest possible maturity date" of the regular interests in the REMIC is

April 25, 2035 for purposes of Code Section 860G(a)(1).

Section 2.06 Optional Substitution of Mortgage Loans.

During the three-month period beginning on the Startup Date, the

Seller shall have the right, but not the obligation, in its sole discretion for

any reason, to substitute for any Mortgage Loan a Substitute Mortgage Loan

meeting the requirements of Section 2.02. Any such substitution shall be carried

out in the manner described in Section 2.02. The Substitution Principal Amount,

if any, plus accrued interest thereon and the other amounts referred to in

Section 2.02, shall be deposited in the Certificate Account.

Agreements. Such account shall be maintained as an Eligible Account. The Master

Servicer shall give notice to each Servicer and the Seller of the location of

the Certificate Account and of any change in the location thereof.

(b) The Master Servicer shall deposit into the Certificate Account

on the day of receipt thereof all amounts received by it from any Servicer

pursuant to any of the Servicing Agreements and shall, in addition, deposit into

the Certificate Account the following amounts, in the case of amounts specified

in clause (i), not later than the Business Day preceding the Distribution Date

on which such amounts are required to be distributed to Certificateholders and,

in the case of the amounts specified in clause (ii), not later than the Business

Day next following the day of receipt and posting by the Master Servicer:

(i) Periodic Advances pursuant to Section 3.03(a) made by the Master

therefor or, where applicable, any Substitution Principal Amount and any

amounts received in respect of the interest portion of unreimbursed

Periodic Advances.

(c) The Master Servicer shall cause the funds in the Certificate

Account to be invested in Eligible Investments. No such Eligible Investments

will be sold or disposed of at a gain prior to maturity unless the Master

Servicer has received an Opinion of Counsel or other evidence satisfactory to it

that such sale or disposition will not cause the Trust Estate to be subject to

Prohibited Transactions Tax, otherwise subject the Trust Estate to tax, or cause

the Trust Estate to fail to qualify as a REMIC while any Certificates are

outstanding. Any amounts deposited in the Certificate Account prior to the

Distribution Date shall be invested for the account of the Master Servicer and

any investment income thereon shall be additional compensation to the Master

Servicer for services rendered under this Agreement. The amount of any losses

incurred in respect of any such investments shall be deposited in the

Certificate Account by the Master Servicer out of its own funds immediately as

realized, without any right of reimbursement therefor from the Trust Estate.

(d) For purposes of this Agreement, the Master Servicer will be

deemed to have received from a Servicer on the applicable Remittance Date for

such funds all amounts deposited by such Servicer into the Custodial P&I Account

maintained in accordance with the applicable Servicing Agreement, if such

Custodial P&I Account is not an Eligible Account as defined in this Agreement,

to the extent such amounts are not actually received by the Master Servicer on

such Remittance Date as a result of the bankruptcy, insolvency, receivership or

other financial distress of the depository institution in which such Custodial

P&I Account is being held. To the extent that amounts so deemed to have been

received by the Master Servicer are subsequently remitted to the Master

Servicer, the Master Servicer shall be entitled to retain such amounts.

Section 3.02 Permitted Withdrawals from the Certificate Account.

(a) The Master Servicer may, from time to time, make withdrawals

from the Certificate Account for the following purposes (limited, in the case of

Servicer reimbursements, to cases where funds in the respective Custodial P&I

Account are not sufficient therefor):

(i) to reimburse the Master Servicer, the Trustee or any Servicer

for Periodic Advances made by the Master Servicer or the Trustee pursuant

to Section 3.03(a) or any Servicer pursuant to any Servicing Agreement

with respect to previous Distribution Dates, such right to reimbursement

pursuant to this subclause (i) being limited to amounts received on or in

respect of particular Mortgage Loans (including, for this purpose,

Liquidation Proceeds, REO Proceeds and proceeds from the purchase, sale,

repurchase or substitution of Mortgage Loans pursuant to Section 2.02,

2.03, 2.06, 3.08 or 9.01) respecting which any such Periodic Advance was

made;

(ii) to reimburse any Servicer, the Master Servicer or the Trustee

for any Periodic Advances determined in good faith to have become

Nonrecoverable Advances;

(iii) to reimburse the Master Servicer or any Servicer from

Liquidation Proceeds for Liquidation Expenses and for amounts expended by

the Master Servicer or any Servicer pursuant hereto or to any Servicing

Agreement, respectively, in good faith in connection with the restoration

of damaged property or for foreclosure expenses;

(iv) from any Mortgagor payment on account of interest or other

recovery (including Net REO Proceeds) with respect to a particular

Mortgage Loan, to pay the Master Servicing Fee with respect to such

Mortgage Loan to the Master Servicer;

(v) to reimburse the Master Servicer, any Servicer or the Trustee

(or, in certain cases, the Seller) for expenses incurred by it (including

taxes paid on behalf of the Trust Estate) and recoverable by or

reimbursable to it pursuant to Section 3.03(c), 3.03(d), 3.09 or 6.03 or

the second sentence of Section 8.13(a) or pursuant to such Servicer's

Servicing Agreement, provided such expenses are "unanticipated" within the

meaning of the REMIC Provisions;

(vi) to pay to the Seller or other purchaser with respect to each

Mortgage Loan or property acquired in respect thereof that has been

repurchased or replaced pursuant to Section 2.02, 2.03, 2.06, 3.08 or 9.01

or auctioned pursuant to Section 3.08, all amounts received thereon and

not required to be distributed as of the date on which the related

repurchase or purchase price or Scheduled Principal Balance was

determined;

(vii) to remit funds to the Paying Agent in the amounts and in the

manner provided for herein;

(viii) to pay to the Master Servicer any interest earned on or

investment income with respect to funds in the Certificate Account;

(ix) to pay to the Master Servicer or any Servicer out of

Liquidation Proceeds allocable to interest the amount of any unpaid Master

Servicing Fee or Servicing Fee (as adjusted pursuant to the related

Servicing Agreement) and any unpaid assumption fees, late payment charges

or other Mortgagor charges on the related Mortgage Loan;

(x) to pay to the Master Servicer as additional master servicing

compensation any Liquidation Profits which a Servicer is not entitled to

pursuant to the applicable Servicing Agreement;

(xi) to withdraw from the Certificate Account any amount deposited

in the Certificate Account that was not required to be deposited therein;

and

(xii) to clear and terminate the Certificate Account pursuant to

Section 9.01.

(b) The Master Servicer shall keep and maintain separate accounting,

on a Mortgage Loan by Mortgage Loan basis, for the purpose of justifying any

payment to and withdrawal from the Certificate Account.

Section 3.03 Advances by Master Servicer and Trustee.

(a) In the event an Other Servicer fails to make any required

Periodic Advances of principal and interest on a Mortgage Loan as required by

the related Other Servicing Agreement prior to the Business Day preceding the

Distribution Date occurring in the month during which such Periodic Advance is

due, the Master Servicer shall make Periodic Advances to the extent provided

hereby. In the event Wells Fargo Bank in its capacity as Servicer fails to make

any required Periodic Advances of principal and interest on a Mortgage Loan as

required by the Wells Fargo Bank Servicing Agreement prior to the Business Day

preceding the Distribution Date occurring in the month during which such

Periodic Advance is due, the Trustee shall, to the extent required by Section

8.14, make such Periodic Advance to the extent provided hereby, provided that

the Trustee has previously received the certificate of the Master Servicer

described in the following sentence. The Master Servicer shall certify to the

Trustee with respect to any such Distribution Date (i) the amount of Periodic

Advances required of Wells Fargo Bank in its capacity as Servicer or such Other

Servicer, as the case may be, (ii) the amount actually advanced by Wells Fargo

Bank in its capacity as Servicer or such Other Servicer, (iii) the amount that

the Trustee or Master Servicer is required to advance hereunder and (iv) whether

the Master Servicer has determined that it reasonably believes that such

Periodic Advance is a Nonrecoverable Advance. Amounts advanced by the Trustee or

Master Servicer shall be deposited in the Certificate Account on the Business

Day preceding the related Distribution Date. Notwithstanding the foregoing,

neither the Master Servicer nor the Trustee will be obligated to make a Periodic

Advance that it reasonably believes to be a Nonrecoverable Advance. The Trustee

may conclusively rely for any determination to be made by it hereunder upon the

determination of the Master Servicer as set forth in its certificate.

(b) To the extent an Other Servicer fails to make an advance on

account of the taxes or insurance premiums with respect to a Mortgage Loan

required pursuant to the related Other Servicing Agreement, the Master Servicer

shall, if the Master Servicer has actual knowledge of such failure of the

Servicer, advance such funds and take such steps as are necessary to pay such

taxes or insurance premiums. To the extent Wells Fargo Bank in its capacity as

Servicer fails to make an advance on account of the taxes or insurance premiums

with respect to a Mortgage Loan required pursuant to the Wells Fargo Bank

Servicing Agreement, the Master Servicer shall, if the Master Servicer knows of

such failure of Wells Fargo Bank in its capacity as Servicer, certify to the

Trustee that such failure has occurred. Upon receipt of such certification, the

Trustee shall advance such funds and take such steps as are necessary to pay

such taxes or insurance premiums.

(c) The Master Servicer and the Trustee shall each be entitled to be

reimbursed from the Certificate Account for any Periodic Advance made by it

under Section 3.03(a) to the extent described in Section 3.02(a)(i). The Master

Servicer and the Trustee shall be entitled to be reimbursed pursuant to Section

3.02(a)(v) for any advance by it pursuant to Section 3.03(b). The Master

Servicer shall diligently pursue restoration of such amount to the Certificate

Account from the related Servicer. The Master Servicer shall, to the extent it

has not already done so, upon the request of the Trustee, withdraw from the

Certificate Account and remit to the Trustee any amounts to which the Trustee is

entitled as reimbursement pursuant to Section 3.02 (a)(i) and (v).

(d) Except as provided in Section 3.03(a) and (b), neither the

Master Servicer nor the Trustee shall be required to pay or advance any amount

which any Servicer was required, but failed, to deposit in the Certificate

Account.

Section 3.04 Custodian to Cooperate; Release of Owner Mortgage Loan

Files and Retained Mortgage Loan Files.

In connection with the deposit by a Servicer into the Certificate

Account of the proceeds from a Liquidated Loan or of a Prepayment in Full, the

Master Servicer or applicable Servicer shall confirm to the Trustee that all

amounts required to be remitted to the Certificate Account in connection with

such Mortgage Loan have been so deposited, and the Master Servicer or applicable

Servicer shall deliver two copies of such Request for Release to the Custodian.

The Custodian shall, within five Business Days of its receipt of such a Request

for Release, release the related Owner Mortgage Loan File (and Retained Mortgage

Loan File, if applicable) to the Master Servicer or such Servicer, as requested

by the Master Servicer or such Servicer. No expenses incurred in connection with

any instrument of satisfaction or deed of reconveyance shall be chargeable to

the Certificate Account.

From time to time and as appropriate for the servicing or

foreclosure of any Mortgage Loan, including but not limited to, collection under

any insurance policies, or to effect a partial release of any Mortgaged Property

from the lien of the Mortgage, the Servicer of such Mortgage Loan shall deliver

to the Master Servicer or Custodian two copies of a Request for Release. Upon

the Master Servicer's receipt of any such Request for Release, the Master

Servicer shall promptly forward such request in hard copy or in electronic

format acceptable to the Custodian. The Custodian shall, within five Business

Days, release the related Owner Mortgage Loan File (and Retained Mortgage Loan

File, if applicable) to the Master Servicer or such Servicer. Any such Request

for Release shall obligate the Master Servicer or such Servicer, as the case may

be, to return the Owner Mortgage Loan File (and Retained Mortgage Loan File, if

applicable) to the Custodian by the twenty-first day following the release

thereof, unless (i) the Mortgage Loan has been liquidated and the Liquidation

Proceeds relating to the Mortgage Loan have been deposited in the Certificate

Account or (ii) the Owner Mortgage Loan File, Retained Mortgage Loan File, if

applicable, or such document has been delivered to an attorney, or to a public

trustee or other public official as required by law, for purposes of initiating

or pursuing legal action or other proceedings for the foreclosure of the

Mortgaged Property either judicially or non-judicially. Upon receipt of two

copies of a Request for Release stating that such Mortgage Loan was liquidated

and that all amounts received or to be received in connection with such

liquidation which are required to be deposited into the Certificate Account have

been so deposited, or that such Mortgage Loan has become an REO Mortgage Loan,

the Custodian shall amend its records.

Upon written certification of the Master Servicer or the Servicer

pursuant to clause (ii) of the preceding paragraph, the Trustee shall execute

and deliver to the Master Servicer or such Servicer, as directed by the Master

Servicer, court pleadings, requests for trustee's sale or other documents

necessary to the foreclosure or trustee's sale in respect of a Mortgaged

Property or to any legal action brought to obtain judgment against any Mortgagor

on the Mortgage Note or Mortgage or to obtain a deficiency judgment, or to

enforce any other remedies or rights provided by the Mortgage Note or Mortgage

or otherwise available at law or in equity. Each such certification shall

include a request that such pleadings or documents be executed by the Trustee

and a statement as to the reason such documents or pleadings are required and

that the execution and delivery thereof by the Trustee will not invalidate or

otherwise affect the lien of the Mortgage, except for the termination of such a

lien upon completion of the foreclosure proceeding or trustee's sale.

Section 3.05 Reports to the Trustee; Annual Compliance Statements.

(a) Not later than 15 days after each Distribution Date, the Master

Servicer shall deliver to the Trustee a statement setting forth the status of

the Certificate Account as of the close of business on such Distribution Date

stating that all distributions required to be made by the Master Servicer under

this Agreement have been made (or, if any required distribution has not been

made by the Master Servicer, specifying the nature and status thereof) and

showing, for the period covered by such statement, the aggregate amount of

deposits into and withdrawals from such account for each category of deposit and

withdrawal specified in Sections 3.01 and 3.02. Such statement may be in the

form of the then current Fannie Mae monthly accounting report for its Guaranteed

Mortgage Pass-Through Program with appropriate additions and changes, and shall

also include information as to the aggregate unpaid principal balance of all of

the Mortgage Loans as of the close of business as of the last day of the

calendar month immediately preceding such Distribution Date. Copies of such

statement shall be provided by the Trustee to any Certificateholder upon written

request, provided such statement is delivered, or caused to be delivered, by the

Master Servicer to the Trustee.

(b) The Master Servicer shall deliver to the Trustee on or before

March 30 of each year, a certificate signed by an officer of the Master

Servicer, certifying that (i) such officer has reviewed the activities of the

Master Servicer during the preceding calendar year or portion thereof and its

performance under this agreement, (ii) to the best of such officer's knowledge,

based on such review, the Master Servicer has performed and fulfilled its

duties, responsibilities and obligations under this agreement in all material

respects throughout such year, or, if there has been a default in the

fulfillment of any such duties, responsibilities or obligations, specifying each

such default known to such officer and the nature and status thereof, and (iii)

(A) the Master Servicer has received from each Servicer any financial

statements, officer's certificates, accountant's statements or other information

required to be provided to the Master Servicer pursuant to the related Servicing

Agreement and (B) to the best of such officer's knowledge, based on a review of

the information provided to the Master Servicer by each Servicer as described in

(iii)(A) above, each Servicer has performed and fulfilled its duties,

responsibilities and obligations under the related Servicing Agreement in all

material respects throughout such year, or, if there has been a default in the

fulfillment of any such duties, responsibilities or obligations, specifying each

such default known to such officer and the nature and status thereof. Copies of

such officers' certificate shall be provided by the Trustee to any

Certificateholder upon written request provided such certificate is delivered,

or caused to be delivered, by the Master Servicer to the Trustee.

Section 3.06 Title, Management and Disposition of Any REO Mortgage

Loan.

The Master Servicer shall enforce the obligations of the applicable

Servicer to administer each REO Mortgage Loan at all times so that each REO

Mortgage Loan qualifies as "foreclosure property" under the REMIC Provisions and

that it does not earn any "net income from foreclosure property" which is

subject to tax under the REMIC Provisions. In the event that a Servicer is

unable to dispose of any REO Mortgage Loan within the period mandated by each of

the Servicing Agreements, the Master Servicer shall monitor such Servicer to

verify that such REO Mortgage Loan is auctioned to the highest bidder within the

period so specified. In the event of any such sale of a REO Mortgage Loan, the

Custodian shall, at the written request of the Master Servicer and upon being

supported with appropriate forms therefor, within five Business Days of the

deposit by the Master Servicer of the proceeds of such sale or auction into the

Certificate Account, release or cause to be released to the entity identified by

the Master Servicer the related Owner Mortgage Loan File, Retained Mortgage Loan

File, if applicable, and Servicer Mortgage Loan File and shall execute and

deliver such instruments of transfer or assignment, in each case without

recourse, as shall be necessary to vest in the auction purchaser title to the

REO Mortgage Loan and the Custodian shall have no further responsibility with

regard to such Owner Mortgage Loan File, Retained Mortgage Loan File, if

applicable, or Servicer Mortgage Loan File. Neither the Trustee, the Master

Servicer nor any Servicer, acting on behalf of the Trust Estate, shall provide

financing from the Trust Estate to any purchaser of an REO Mortgage Loan.

Section 3.07 Amendments to Servicing Agreements, Modification of

Standard Provisions.

(a) Subject to the prior written consent of the Trustee pursuant to

Section 3.07(b), the Master Servicer from time to time may, to the extent

permitted by the applicable Servicing Agreement, make such modifications and

amendments to such Servicing Agreement as the Master Servicer deems necessary or

appropriate to confirm or carry out more fully the intent and purpose of such

Servicing Agreement and the duties, responsibilities and obligations to be

performed by the Servicer thereunder. Such modifications may only be made if

they are consistent with the REMIC Provisions, as evidenced by an Opinion of

Counsel. Prior to the issuance of any modification or amendment, the Master

Servicer shall deliver to the Trustee such Opinion of Counsel and an Officer's

Certificate setting forth (i) the provision that is to be modified or amended,

(ii) the modification or amendment that the Master Servicer desires to issue and

(iii) the reason or reasons for such proposed amendment or modification.

(b) The Trustee shall consent to any amendment or supplement to a

Servicing Agreement proposed by the Master Servicer pursuant to Section 3.07(a),

which consent and amendment shall not require the consent of any

Certificateholder if it is (i) for the purpose of curing any mistake or

ambiguity or to further effect or protect the rights of the Certificateholders

or (ii) for any other purpose, provided such amendment or supplement for such

other purpose cannot reasonably be expected to adversely affect

Certificateholders. The lack of reasonable expectation of an adverse effect on

Certificateholders may be established through the delivery to the Trustee of (i)

an Opinion of Counsel to such effect or (ii) written notification from each

Rating Agency to the effect that such amendment or supplement will not result in

reduction of the current rating assigned by that Rating Agency to the

Certificates. Notwithstanding the two immediately preceding sentences, the

Trustee may, in its discretion, decline to enter into or consent to any such

supplement or amendment if its own rights, duties or immunities shall be

adversely affected.

(c)(i) Notwithstanding anything to the contrary in this Section

3.07, the Master Servicer from time to time may, without the consent of any

Certificateholder or the Trustee, enter into an amendment (A) to an Other

Servicing Agreement for the purpose of (i) eliminating or reducing Month End

Interest and (ii) providing for the remittance of Full Unscheduled Principal

Receipts by the applicable Servicer to the Master Servicer not later than the

24th day of each month (or if such day is not a Business Day, on the previous

Business Day) or (B) to the Wells Fargo Bank Servicing Agreement for the purpose

of changing the applicable Remittance Date to the 18th day of each month (or if

such day is not a Business Day, on the previous Business Day).

(ii) The Master Servicer may direct Wells Fargo Bank in its capacity

as Servicer to enter into an amendment to the Wells Fargo Bank Servicing

Agreement for the purposes described in Section 3.07(c)(i)(B).

Section 3.08 Oversight of Servicing.

The Master Servicer shall supervise, monitor and oversee the

servicing of the Mortgage Loans by each Servicer and the performance by each

Servicer of all services, duties, responsibilities and obligations (including

the obligation to maintain an Errors and Omissions Policy and Fidelity Bond)

that are to be observed or performed by the Servicer under its respective

Servicing Agreement. In performing its obligations hereunder, the Master

Servicer shall act in a manner consistent with Accepted Master Servicing

Practices and in a manner consistent with the terms and provisions of any

insurance policy required to be maintained by the Master Servicer or any

Servicer pursuant to this Agreement or any Servicing Agreement. The Master

Servicer acknowledges that prior to taking certain actions required to service

the Mortgage Loans, each Servicing Agreement provides that the Servicer

thereunder must notify, consult with, obtain the consent of or otherwise follow

the instructions of the Master Servicer. The Master Servicer is also given

authority to waive compliance by a Servicer with certain provisions of its

Servicing Agreement. In each such instance, the Master Servicer shall promptly

instruct such Servicer or otherwise respond to such Servicer's request. In no

event will the Master Servicer instruct such Servicer to take any action, give

any consent to action by such Servicer or waive compliance by such Servicer with

any provision of such Servicer's Servicing Agreement if any resulting action or

failure to act would be inconsistent with the requirements of the Rating

Agencies that rated the Certificates or would otherwise have an adverse effect

on the Certificateholders. Any such action or failure to act shall be deemed to

have an adverse effect on the Certificateholders if such action or failure to

act either results in (i) the downgrading of the rating assigned by either

Rating Agency to the Certificates, (ii) the loss by the Trust Estate of REMIC

status for federal income tax purposes or (iii) the imposition of any Prohibited

Transaction Tax or any federal taxes on either the REMIC or the Trust Estate.

The Master Servicer shall have full power and authority in its sole discretion

to take any action with respect to the Trust Estate as may be necessary or

advisable to avoid the circumstances specified including clause (ii) or (iii) of

the preceding sentence.

For the purposes of determining whether any modification of a

Mortgage Loan shall be permitted by the Master Servicer, such modification shall

be construed as a substitution of the modified Mortgage Loan for the Mortgage

Loan originally deposited in the Trust Estate if it would be a "significant

modification" within the meaning of Section 1.860G-2(b) of the regulations of

the U.S. Department of the Treasury. No modification shall be approved unless

(i) the modified Mortgage Loan would qualify as a Substitute Mortgage Loan under

Section 2.02 and (ii) with respect to any modification that occurs more than

three months after the Closing Date and is not the result of a default or a

reasonably foreseeable default under the Mortgage Loan, there is delivered to

the Trustee an Opinion of Counsel (at the expense of the party seeking to modify

the Mortgage Loan) to the effect that such modification would not be treated as

giving rise to a new debt instrument for federal income tax purposes as

described in the preceding sentence; provided, however, that no such Opinion of

Counsel need be delivered if the sole purpose of the modification is to reduce

the Monthly Payment on a Mortgage Loan as a result of a Curtailment such that

the Mortgage Loan is fully amortized by its original maturity date.

During the term of this Agreement, the Master Servicer shall consult

fully with each Servicer as may be necessary from time to time to perform and

carry out the Master Servicer's obligations hereunder and otherwise exercise

reasonable efforts to cause such Servicer to perform and observe the covenants,

obligations and conditions to be performed or observed by it under its Servicing

Agreement.

The relationship of the Master Servicer to the Trustee under this

Agreement is intended by the parties to be that of an independent contractor and

not that of a joint venturer, partner or agent.

The Master Servicer shall administer the Trust Estate on behalf of

the Trustee and shall have full power and authority, acting alone or (subject to

Section 6.06) through one or more subcontractors, to do any and all things in

connection with such administration which it may deem necessary or desirable.

Upon the execution and delivery of this Agreement, and from time to time as may

be required thereafter, the Trustee shall furnish the Master Servicer or its

subcontractors with any powers of attorney and such other documents as may be

necessary or appropriate to enable the Master Servicer to carry out its

administrative duties hereunder.

The Seller shall have a limited option to repurchase any defaulted

Mortgage Loan or REO Mortgage Loan during the following time periods: (i)

beginning on the first day of the second month following the month in which the

Master Servicer has reported that a Servicer has initiated foreclosure

proceedings with respect to such a defaulted Mortgage Loan, with such repurchase

option expiring on the last day of such second following month; (ii) beginning

on the first day of the second month following the month in which the Master

Servicer has reported that such defaulted Mortgage Loan has become an REO

Mortgage Loan, with such repurchase option expiring on the last day of such

second following month; and (iii) beginning on the day on which a Servicer

accepts a contractual commitment by a third party to purchase the Mortgaged

Property related to the defaulted Mortgage Loan or REO Mortgage Loan, with such

repurchase option expiring on the earlier of the last day of the month in which

such contractual commitment was accepted by the Servicer or the day immediately

prior to the day on which the closing occurs with respect to such third party

purchase of the Mortgaged Property related to the defaulted Mortgage Loan or REO

Mortgage Loan. The Seller shall be entitled to repurchase at its option any

Mortgage Loan in the Trust Estate which, pursuant to paragraph 5(b) of the

Mortgage Loan Purchase Agreement, Wells Fargo Bank requests the Seller to

repurchase and to sell to Wells Fargo Bank to facilitate the exercise of Wells

Fargo Bank's rights against the originator or a prior holder of such Mortgage

Loan. The purchase price for any Mortgage Loan repurchased pursuant to this

paragraph shall be 100% of the unpaid principal balance of such Mortgage Loan

plus accrued interest thereon at the Mortgage Interest Rate for such Mortgage

Loan, through the last day of the month in which such repurchase occurs. Upon

the receipt of such purchase price, the Master Servicer shall provide to the

Trustee the certification required by Section 3.04 and the Trustee and the

Custodian, if any, shall promptly release to the Seller the Owner Mortgage Loan

File and Retained Mortgage Loan File, if applicable, relating to the Mortgage

Loan being repurchased.

In the event that (i) the Master Servicer determines at any time

that, notwithstanding the representations and warranties set forth in Section

2.03(b), any Mortgage Loan is not a "qualified mortgage" within the meaning of

Section 860G of the Code and (ii) the Trustee is unable to enforce the

obligation of the Seller to purchase such Mortgage Loan pursuant to Section 2.02

within two months of such determination, the Master Servicer shall cause such

Mortgage Loan to be auctioned to the highest bidder and sold out of the Trust

Estate no later than the date 90 days after such determination. In the event of

any such sale of a Mortgage Loan, the Custodian shall, at the written request of

the Master Servicer and upon being supported with appropriate forms therefor,

within five Business Days of the deposit by the Master Servicer of the proceeds

of such auction into the Certificate Account, release or cause to be released to

the entity identified by the Master Servicer the related Owner Mortgage Loan

File, Retained Mortgage Loan File, if applicable, and Servicer Mortgage Loan

File and shall execute and deliver such instruments of transfer or assignment,

in each case without recourse, as shall be necessary to vest in the auction

purchaser title to the Mortgage Loan and the Custodian shall have no further

responsibility with regard to such Owner Mortgage Loan File, Retained Mortgage

Loan File, if applicable, or Servicer Mortgage Loan File. None of the Trustee,

the Cust
