THIS AMENDMENT to the Servicing Agreement dated as of March 1, 2002, between WELLS FARGO BANK MINNESOTA, NATIONAL ASSOCIATION, as Master Servicer, THORNBURG MORTGAGE HOME LOANS, INC. (“TMHL”), as Seller and as Servicer (the “Servicing Agreement”) is made as of the 1st day of December, 2002, by and between the MASTER SERVICER, the SERVICER and the SELLER (the “Amendment”).

WITNESSETH:

WHEREAS, TMHL and the Master Servicer are parties to the Servicing Agreement wherein the Servicer has agreed to service Securitized Loans pursuant to the terms of the Servicing Agreement;

WHEREAS, the Master Servicer has requested that certain additional servicing certifications be provided to the Master Servicer and that certain time periods for the provision of reports be modified, and the Servicer has agreed to such modifications; and

WHEREAS, the Master Servicer and TMHL desire to amend the Servicing Agreement to reflect those requirements;

NOW, THEREFORE, for and in consideration of good and valuable consideration, the receipt and sufficiency of which are hereby acknowledged, and of the mutual covenants herein contained, the parties hereto hereby agree as follows:

1. Capitalized terms used and not defined in this Amendment shall have the meanings given to such terms in the Servicing Agreement.

2. Article I entitled “Definitions” is amended as follows:

a. The definition of “Agreement” is modified to read as follows:

“This Servicing Agreement, as amended by that certain Amendment to Servicing Agreement dated as of December 1, 2002, and all other amendments hereof and supplements hereto.”

b. The definition of “Sub-Servicing Acknowledgment Agreement” is modified to read as follows:

“That certain Sub-Servicing Acknowledgment Agreement, dated as of March 1, 2002, by and between the Servicer and the Sub-Servicer, as amended by that certain Amendment to Sub-Servicing Acknowledgment Agreement, dated as of December 1, 2002 by and between the Servicer and the Sub-Servicer.”

3. Section 5.02 entitled “Annual Audit Report” is amended by:

a. deleting the phrase “Not more than ninety (90) days after the end of the Servicer’s fiscal year” in the first sentence; and after the phrase “own expense” add the following: “use its best efforts by March 20 of each year, but in no event later than March 30 of each year,”; and

b. deleting the phrase “commencing with the fiscal year ending December 31, 2002” in the first sentence. Therefore, Section 5.02 now reads in its entirety as follows:

The Servicer shall, at its own expense, use its best efforts by March 20 of each year, but in no event later than March 30 of each year, cause a firm of independent public accountants (who may also render other services to Servicer), which is a member of the American Institute of Certified Public Accountants, to furnish to the Seller and the Master Servicer (i) year-end audited (if available) financial statements of the Servicer and (ii) a statement to the effect that such firm has examined certain documents and records for the preceding fiscal year (or during the period from the date of commencement of such Servicer’s duties hereunder until the end of such preceding fiscal year in the case of the first such certificate) and that, on the basis of such examination conducted substantially in compliance with the Uniform Single Attestation Program for Mortgage Bankers, such firm is of the opinion that Servicer’s overall servicing operations have been conducted in compliance with the Uniform Single Attestation Program for Mortgage Bankers except for such exceptions that, in the opinion of such firm, the Uniform Single Attestation Program for Mortgage Bankers requires it to report, in which case such exceptions shall be set forth in such statement.

4. Section 5.03 entitled “Annual Officer’s Certificate” is amended by:

b. deleting the phrase “commencing with the fiscal year ending December 31, 2002” in the first sentence.

Therefore, Section 5.03 now reads in its entirety as follows:

The Servicer, at its own expense, will, using its best efforts by March 20 of each year, but in no event later than March 30 of each year, deliver to the Seller and the Master Servicer a Servicing Officer’s certificate stating, as to each signer thereof, that (i) a review of the activities of the Servicer during such preceding fiscal year and of performance under this Agreement has been made under such officers’ supervision, and (ii) to the best of such officers’ knowledge, based on such review, the Servicer has fulfilled all its obligations under this Agreement for such year, or, if there has been a default in the fulfillment of all such obligations, specifying each such default known to such officers and the nature and status thereof including the steps being taken by the Servicer to remedy such default.

(ii) The servicing information required to be provided to the Master Servicer by the Servicer under this Servicing Agreement has been provided to the Master Servicer;

(iii) I am responsible for reviewing the activities performed by the Servicer under the Servicing Agreement and based upon the review required by the Servicing Agreement, and except as disclosed in the annual statement of compliance, the annual independent public accountant’s servicing report and all servicing reports, officer’s certificates and other information relating to the servicing of the Securitized Loans submitted to the Master Servicer, the Servicer has, as of the date of this certification fulfilled its obligations under the Servicing Agreement; and

(iv) I have disclosed to the Master Servicer all significant deficiencies relating to the Servicer’s compliance with the minimum servicing standards in accordance with a review conducted in compliance with the Uniform Single Attestation Program for Mortgage Bankers or similar standard as set forth in the Servicing Agreement.

(iii) any breach by TMHL of a representation or warranty set forth in Section 4(a) or in a writing furnished pursuant to Section 4(b) and made as of a date prior to the closing date of the related Securitization Transaction, to the extent that such breach is not cured by such closing date, or any breach by TMHL of a representation or warranty in a writing furnished pursuant to Section 4(b) to the extent made as of a date subsequent to such closing date; or

This indemnification shall survive the termination of this Amendment or the termination of any party to this Amendment.

(ii) Any failure by TMHL, any Subservicer or any Subcontractor to deliver any information, report, certification or accountants’ letter when and as required under Section 6, including (except as provided below) any failure by TMHL to identify pursuant to Section 3 any Subcontractor “participating in the servicing function” within the meaning of Item 1122 of Regulation AB, which failure continues unremedied for a period of ten (10) calendar days after the date on which written notice of such failure, requiring the same to have been remedied, shall have been given to TMHL by the Master Servicer or Depositor, shall constitute an Event of Default with respect to TMHL under this Amendment, and shall entitle the Purchaser, Master Servicer or Depositor, as applicable, in its sole discretion to terminate the rights and obligations of TMHL as servicer pursuant to the terms of this Amendment; provided that to the extent that any provision of this Amendment expressly provides for the survival of certain rights or obligations following termination of TMHL as servicer, such provision shall be given effect.

-6-

Neither the Master Servicer nor any Depositor shall be entitled to terminate the rights and obligations of TMHL pursuant to this subparagraph (b)(ii) if a failure of TMHL to identify a Subcontractor “participating in the servicing function” within the meaning of Item 1122 of Regulation AB was attributable solely to the role or functions of such Subcontractor with respect to mortgage loans other than the Mortgage Loans.
