                             PRELIMINARY STATEMENT:

 

                  The Depositor intends to sell pass-through certificates to be

Agreement.

 

                                      REMIC I

                                     -------

 

                  As provided herein, the Trustee will elect to treat the

segregated pool of assets consisting of the Mortgage Loans and certain other

related assets (other than the Net WAC Rate Carryover Reserve Account and the

Cap Contracts) subject to this Agreement as a REMIC for federal income tax

purposes, and such segregated pool of assets will be designated as "REMIC I."

The Class R-I Interest will be the sole class of "residual interests" in REMIC I

for purposes of the REMIC Provisions (as defined herein). The following table

irrevocably sets forth the designation, the REMIC I Remittance Rate, the initial

Uncertificated Balance and, for purposes of satisfying Treasury regulation

I-LTM8, REMIC I Regular Interest I-LTM9, REMIC I Regular Interest I-LTM10 and

REMIC I Regular Interest I-LTM11 and any Accrual Period therefor, the rate

determined by the Trust Administrator on the related Interest Determination Date

on the basis of the offered rate for one-month U.S. dollar deposits, as such

rate appears on Telerate Page 3750 as of 11:00 a.m. (London time) on such

Interest Determination Date; provided that if such rate does not appear on

Telerate Page 3750, the rate for such date will be determined on the basis of

the offered rates of the Reference Banks for one-month U.S. dollar deposits, as

of 11:00 a.m. (London time) on such Interest Determination Date. In such event,

the Trust Administrator will request the principal London office of each of the

Reference Banks to provide a quotation of its rate. If on such Interest

Determination Date, two or more Reference Banks provide such offered quotations,

One-Month LIBOR for the related Accrual Period shall be the arithmetic mean of

such offered quotations (rounded upwards if necessary to the nearest whole

Interest Determination Date and (ii) the Reserve Interest Rate. Notwithstanding

the foregoing, if, under the priorities described above, LIBOR for an Interest

Determination Date would be based on LIBOR for the previous Interest

Determination Date for the third consecutive Interest Determination Date, the

Trustee or the Custodian, as applicable, within three Business Days.

 

                   Except with respect to any Mortgage Loan for which MERS is

Custodian, as applicable, shall promptly (within sixty Business Days following

the later of the Closing Date and the date of receipt by the such party of the

recording information for a Mortgage, but in no event later than ninety days

is lost or returned unrecorded because of a defect therein, the Trustee shall

enforce the obligation of the related Originator or the Seller pursuant to the

Master Agreement or the Mortgage Loan Purchase Agreement to promptly prepare or

cause to be prepared a substitute Assignment or cure or cause to be cured such

defect, as the case may be, and thereafter cause each such Assignment to be duly

recorded.

 

                  In connection with the assignment of any Mortgage Loan

registered on the MERS(R) System, the Depositor further agrees that it will

cause, within 30 Business Days after the Closing Date, the MERS(R) System to

indicate that such Mortgage Loans have been assigned by the Depositor to the

which are repurchased in accordance with this Agreement) in such computer files

(a) the code in the field which identifies the specific Trustee and (b) the code

in the field "Pool Field" which identifies the series of the Certificates issued

in connection with such Mortgage Loans. The Depositor further agrees that it

will not, and will not permit the Master Servicer to, and the Master Servicer

agrees that it will not, alter the codes referenced in this paragraph with

                  If any of the documents referred to in Sections 2.01(ii),

(iii) or (iv) has, as of the Closing Date, been submitted for recording but

either (x) has not been returned from the applicable public recording office or

(y) has been lost or such public recording office has retained the original of

such document, the obligations of the Depositor to deliver such documents shall

be deemed to be satisfied upon (1) delivery to the Trust Administrator, the

Trustee or the Custodian, as applicable, of a copy of each such document

certified by the related Originator or the Seller in the case of (x) above or

copy is certified by the applicable Originator or the Seller, delivery to the

Trust Administrator, the Trustee or the Custodian, as applicable, promptly upon

                  If the original lender's title insurance policy was not

Loan.

 

                  All original documents relating to the Mortgage Loans that are

not delivered to the Trust Administrator, the Trustee or the Custodian, as

applicable, are and shall be held by or on behalf of the related Originator, the

Seller, the Depositor, the related Servicer or the Master Servicer, as the case

may be, in trust for the benefit of the Trustee on behalf of the

Certificateholders. In the event that any such original document is required

pursuant to the terms of this Section 2.01 to be a part of a Mortgage File, such

document shall be delivered promptly to the Trust Administrator, the Trustee or

the Custodian, as applicable. Any such original document delivered to or held by

the Depositor that is not required pursuant to the terms of this Section to be a

part of a Mortgage File, shall be delivered promptly to the related Servicer.

acknowledge receipt, subject to the provisions of Section 2.01 and subject to

any exceptions noted on the exception report described in the next paragraph

below, the documents referred to in Section 2.01 with respect to the related

Mortgage Loans (other than such documents described in Section 2.01(v)) above

and all other assets included in the definition of "REMIC I" under clauses (i),

(iii), (iv) and (v) (to the extent of amounts deposited into the Distribution

Account) and declares that it holds and will hold such documents and the other

documents delivered to it constituting a Mortgage File, and that it holds or

will hold all such assets and such other assets included in the definition of

"REMIC I" in trust for the exclusive use and benefit of all present and future

Certificateholders.

 

                  The Trust Administrator and the Trustee each agree to execute

and deliver with respect to the related Mortgage Files, and the Trustee agrees

to cause the Custodian to execute and deliver (in the form attached to the

Custodial Agreement), to the Depositor and the NIMS Insurer on or prior to the

Closing Date, an acknowledgment of receipt of the original Mortgage Note (with

any exceptions noted), substantially in the form attached as Exhibit C-3 hereto.

 

                  The Trust Administrator, the Trustee and the Custodian each

agree, for the benefit of the Certificateholders and the NIMS Insurer, to review

the Mortgage Files held by such party and, within 45 days of the Closing Date

and to certify in substantially the form attached hereto as Exhibit C-1 (or

cause the Custodian with respect to the Deutsche Bank Files to certify in the

form of the Initial Certification attached to the Custodial Agreement) that, as

to each Mortgage Loan listed in the Mortgage Loan Schedule (other than any

Mortgage Loan paid in full or any Mortgage Loan specifically identified in the

exception report annexed thereto as not being covered by such certification),

(i) all documents constituting part of such Mortgage File (other than such

documents described in Section 2.01(v)) required to be delivered to it pursuant

to this Agreement are in its possession, (ii) such documents have been reviewed

by it and appear regular on their face and relate to such Mortgage Loan and

(iii) based on its examination and only as to the foregoing, the information set

forth in the Mortgage Loan Schedule that corresponds to items (i), (iii), (x),

(xi), (xii), (xv) and (xviii) of the definition of "Mortgage Loan Schedule"

accurately reflects information set forth in the Mortgage File. It is herein

acknowledged that, in conducting such review, the Trust Administrator, the

Trustee or the Custodian, as applicable, is under no duty or obligation (i) to

inspect, review or examine any such documents, instruments, certificates or

other papers to determine whether they are genuine, enforceable, or appropriate

for the represented purpose or whether they have actually been recorded or that

they are other than what they purport to be on their face or (ii) to determine

whether any Mortgage File should include any of the documents specified in

clause (v) of Section 2.01.

 

                  Prior to the first anniversary date of this Agreement the

Trust Administrator, the Trustee and the Custodian shall deliver to the

Depositor, the NIMS Insurer, the Trustee, the Servicers and the Master Servicer

a final certification with respect to the related Mortgage Files, in the form

annexed hereto as Exhibit C-2 (or, with respect to the Custodian, in the form

attached to the Custodial Agreement) evidencing the completeness of such

Mortgage Files, with any applicable exceptions noted thereon.

 

                  If in the process of reviewing the Mortgage Files and making

or preparing, as the case may be, the certifications referred to above, the

Trust Administrator, the Trustee or the Custodian finds any document or

documents constituting a part of a Mortgage File to be missing or defective in

any material respect, at the conclusion of its review, such party shall so

notify the Depositor, the NIMS Insurer, the Trustee, the Servicers and the

Master Servicer. In addition, upon the discovery by the Depositor, the NIMS

Insurer, the Servicers, the Master Servicer or the Trustee of a breach of any of

the representations and warranties made by an Originator or the Seller in the

Master Agreements or the Mortgage Loan Purchase Agreement, as applicable, in

respect of any Mortgage Loan which materially adversely affects such Mortgage

Loan or the interests of the related Certificateholders in such Mortgage Loan,

the party discovering such breach shall give prompt written notice to the other

parties.

 

                  The Trust Administrator, the Trustee or the Custodian, as

applicable shall, at the written request and expense of any Certificateholder,

provide a written report to such Certificateholder of all related Mortgage Files

released to the Servicers for servicing purposes.

 

                  The Depositor and the Trustee intend that the assignment and

transfer herein contemplated constitute a sale of the Mortgage Loans, the

related Mortgage Notes and the related documents, conveying good title thereto

free and clear of any liens and encumbrances, from the Depositor to the Trustee

in trust for the benefit of the Certificateholders and that such property not be

part of the Depositor's estate or property of the Depositor in the event of any

insolvency by the Depositor. In the event that such conveyance is deemed to be,

or to be made as security for, a loan, the parties intend that the Depositor

shall be deemed to have granted and does hereby grant to the Trustee a first

                  SECTION 2.03. Repurchase or Substitution of Mortgage Loans by

                                an Originator or the Seller.

 

                  (a) Upon discovery or receipt of notice of any materially

defective document in, or that a document is missing from, a Mortgage File or of

the breach by an Originator or the Seller of any representation, warranty or

covenant under the Master Agreements, the Originator Assignment Agreements or

the Mortgage Loan Purchase Agreement, as applicable, (including any

representation, warranty or covenant regarding the Prepayment Charge Schedule)

in respect of any Mortgage Loan that materially adversely affects the value of

such Mortgage Loan or the interest therein of the Certificateholders, the Trust

Administrator or the Trustee (who shall have received notice from the

Custodian), as applicable, shall promptly notify the related Originator, the

NIMS Insurer, the Seller, the Servicers and the Master Servicer of such defect,

missing document or breach and request that the related Originator or the

Seller, as applicable, deliver such missing document or cure such defect or

breach within 90 days from the date such Originator or the Seller, as

applicable, was notified of such missing document, defect or breach, and if the

related Originator or the Seller, as applicable, does not deliver such missing

document or cure such defect or breach in all material respects during such

period, the Trustee shall enforce the obligations of the related Originator or

the Seller, as applicable, under the related Maser Agreement, the related

Originator Assignment Agreement or the Mortgage Loan Purchase Agreement, as

applicable, to repurchase such Mortgage Loan from REMIC I at the Purchase Price

within 90 days after the date on which the related Originator or the Seller, as

applicable, was notified (subject to Section 2.03(c)) of such missing document,

defect or breach, if and to the extent that the related Originator or the

Seller, as applicable, is obligated to do so under the related Master Agreement,

the related Originator Assignment Agreement or the Mortgage Loan Purchase

Agreement, as applicable. The Purchase Price for the repurchased Mortgage Loan

shall be remitted to the Master Servicer for deposit into the Distribution

Account and the Trust Administrator, the Trustee or the Custodian, as

applicable, upon receipt of written notice from the Master Servicer of such

deposit, shall release to the related Originator or the Seller, as applicable,

the related Mortgage File and such party shall execute and deliver such

instruments of transfer or assignment, in each case without recourse, as the

related Originator or the Seller, as applicable, shall furnish to it and as

shall be necessary to vest in the related Originator or the Seller, as

applicable, any Mortgage Loan released pursuant hereto. In furtherance of the

foregoing, if the related Originator or the Seller, as applicable, is not a

member of MERS and repurchases a Mortgage Loan which is registered on the

MERS(R) System, the related Originator or the Seller, as applicable, at its own

expense and without any right of reimbursement, shall cause MERS to execute and

deliver an assignment of the Mortgage in recordable form to transfer the

Mortgage from MERS to the related Originator or the Seller, as applicable, and

shall cause such Mortgage to be removed from registration on the MERS(R) System

in accordance with MERS' rules and regulations. The Trust Administrator, the

Trustee or the Custodian, as applicable, shall not have any further

responsibility with regard to such Mortgage File. In lieu of repurchasing any

such Mortgage Loan as provided above, if so provided in the related Master

Agreement or the Mortgage Loan Purchase Agreement, the related Originator or the

Seller, as applicable, may cause such Mortgage Loan to be removed from REMIC I

(in which case it shall become a Deleted Mortgage Loan) and substitute one or

more Qualified Substitute Mortgage Loans in the manner and subject to the

limitations set forth in Section 2.03(b); provided, however, the related

Originator or the Seller, as applicable, may not substitute a Qualified

Substitute Mortgage Loan for any Deleted Mortgage Loan that violates any

predatory or abusive lending law. It is understood and agreed that the

obligation of an Originator or the Seller, as applicable, to cure or to

repurchase (or to substitute for) any Mortgage Loan as to which a document is

missing, a material defect in a constituent document exists or as to which such

a breach has occurred and is continuing shall constitute the sole remedy

respecting such omission, defect or breach available to the Trustee and the

Certificateholders.

 

                  (b) Any substitution of Qualified Substitute Mortgage Loans

for Deleted Mortgage Loans made pursuant to Section 2.03(a) must be effected

prior to the date which is two years after the Startup Day for REMIC I.

 

                  As to any Deleted Mortgage Loan for which an Originator or the

Seller, as applicable, substitutes a Qualified Substitute Mortgage Loan or

Loans, such substitution shall be effected by the related Originator or the

Seller, as applicable, delivering to the Trust Administrator, the Trustee or the

Custodian, as applicable, for such Qualified Substitute Mortgage Loan or Loans,

the Mortgage Note, the Mortgage, the Assignment in blank or to the Trustee, and

such other documents and agreements, with all necessary endorsements thereon, as

are required by Section 2.01, together with an Officers' Certificate providing

that each such Qualified Substitute Mortgage Loan satisfies the definition

thereof and specifying the Substitution Adjustment Amount (as described below),

if any, in connection with such substitution. The Trust Administrator, the

Trustee or the Custodian, as applicable, shall acknowledge receipt for such

Qualified Substitute Mortgage Loan or Loans and, within ten Business Days

thereafter, review such documents as specified in Section 2.02 and deliver to

the Depositor, the NIMS Insurer, the Servicers and the Master Servicer, with

respect to such Qualified Substitute Mortgage Loan or Loans, a certification

substantially in the form attached hereto as Exhibit C-1, with any applicable

exceptions noted thereon. Within one year of the date of substitution, the Trust

Administrator, the Trustee or the Custodian, as applicable, shall deliver to the

Depositor, the NIMS Insurer, the Servicers and the Master Servicer a

certification substantially in the form of Exhibit C-2 hereto with respect to

such Qualified Substitute Mortgage Loan or Loans, with any applicable exceptions

noted thereon. Monthly Payments due with respect to Qualified Substitute

Mortgage Loans in the month of substitution are not part of REMIC I and will be

retained by the related Originator or the Seller, as applicable. For the month

of substitution, distributions to Certificateholders will reflect the Monthly

Payment due on such Deleted Mortgage Loan on or before the Due Date in the month

of substitution, and the related Originator or the Seller, as applicable, shall

thereafter be entitled to retain all amounts subsequently received in respect of

such Deleted Mortgage Loan. The Depositor shall give or cause to be given

written notice to the Certificateholders and the NIMS Insurer that such

substitution has taken place, shall amend the Mortgage Loan Schedule to reflect

the removal of such Deleted Mortgage Loan from the terms of this Agreement and

the substitution of the Qualified Substitute Mortgage Loan or Loans and shall

deliver a copy of such amended Mortgage Loan Schedule to the Master Servicer,

the Trust Administrator, the Custodian, the related Servicer and the NIMS

Insurer. Upon such substitution, such Qualified Substitute Mortgage Loan or

Loans shall constitute part of the Mortgage Pool and shall be subject in all

respects to the terms of this Agreement and the related Master Agreement, the

related Originator Assignment Agreement or the Mortgage Loan Purchase Agreement,

as applicable, including, all applicable representations and warranties thereof

included in the related Master Agreement, the related Originator Assignment

Agreement or Mortgage Loan Purchase Agreement, as applicable.

 

                  For any month in which an Originator or the Seller, as

applicable, substitutes one or more Qualified Substitute Mortgage Loans for one

or more Deleted Mortgage Loans, the Master Servicer will monitor the obligation

of the related Servicer, to the extent provided in the related Servicing

Agreement, to determine the amount (the "Substitution Adjustment Amount"), if

any, by which the aggregate Purchase Price of all such Deleted Mortgage Loans

exceeds the aggregate of, as to each such Qualified Substitute Mortgage Loan,

the Stated Principal Balance thereof as of the date of substitution, together

with one month's interest on such Stated Principal Balance at the applicable Net

Mortgage Rate, plus all outstanding Advances and Servicing Advances (including

Nonrecoverable Advances and Nonrecoverable Servicing Advances) related thereto.

If the related Servicing Agreement does not require the related Servicer to

determine the Substitution Adjustment Amount, the Master Servicer, based on

information provided to it by the related Servicer, shall determine the

Substitution Adjustment Amount. Upon receipt of the related Servicer's

determination of the Substitution Adjustment Amount or upon determination by the

Master Servicer of the Substitution Adjustment Amount, the Master Servicer shall

give prompt written notice thereof to the Trust Administrator. On the date of

such substitution, the related Originator or the Seller, as applicable, will

deliver or cause to be delivered to the Master Servicer for deposit in the

Distribution Account an amount equal to the Substitution Adjustment Amount, if

any, and the Trust Administrator, the Trustee or the Custodian, as applicable,

upon receipt of the related Qualified Substitute Mortgage Loan or Loans and

written notice by the Master Servicer of such deposit, shall release to the

related Originator or the Seller, as applicable, the related Mortgage File or

Files and such party shall execute and deliver such instruments of transfer or

assignment, in each case without recourse, the related Originator or the Seller,

as applicable, shall deliver to it and as shall be necessary to vest therein any

Deleted Mortgage Loan released pursuant hereto.

 

                  In addition, the related Originator or the Seller, as

applicable, shall obtain at its own expense and deliver to the Trustee, the

Trust Administrator and the NIMS Insurer an Opinion of Counsel to the effect

that such substitution will not cause (a) any federal tax to be imposed on any

Trust REMIC, including without limitation, any federal tax imposed on

"prohibited transactions" under Section 860F(a)(1) of the Code or on

"contributions after the startup date" under Section 860G(d)(1) of the Code, or

(b) any Trust REMIC to fail to qualify as a REMIC at any time that any

Certificate is outstanding.

 

                  (c) Upon discovery by the Depositor, the NIMS Insurer, an

Originator, the Seller, the Master Servicer, the Trust Administrator or the

Trustee that any Mortgage Loan does not constitute a "qualified mortgage" within

the meaning of Section 860G(a)(3) of the Code, the party discovering such fact

shall within two Business Days give written notice thereof to the other parties

hereto and the Trustee shall give written notice to the related Originator and

the Seller. In connection therewith, the related Originator, the Seller or the

Depositor shall repurchase or, subject to the limitations set forth in Section

2.03(b), substitute one or more Qualified Substitute Mortgage Loans for the

affected Mortgage Loan within 90 days of the earlier of discovery or receipt of

such notice with respect to such affected Mortgage Loan. Such repurchase or

substitution shall be made by (i) the related Originator or the Seller, as the

case may be, if the affected Mortgage Loan's status as a non-qualified mortgage

is or results from a breach of any representation, warranty or covenant made by

such Originator or the Seller, as the case may be, under the related Master

Agreement or the Mortgage Loan Purchase Agreement, as applicable, or (ii) the

Depositor, if the affected Mortgage Loan's status as a non-qualified mortgage is

a breach of no representation or warranty. Any such repurchase or substitution

shall be made in the same manner as set forth in Section 2.03(a). The Trust

Administrator, the Trustee or the Custodian, as applicable, shall reconvey to

the Depositor, the related Originator or the Seller, as the case may be, the

Mortgage Loan to be released pursuant hereto in the same manner, and on the same

terms and conditions, as it would a Mortgage Loan repurchased for breach of a

representation or warranty.
