In accordance with Section 2.07, the Company shall deliver at its own expense, the Mortgage Files for the related Mortgage Loans to Purchaser or its designee. The possession of each Servicing File by the Company is at the will of the Purchaser, for the sole purpose of interim servicing the related Mortgage Loan prior to the related Servicing Transfer Date, and such retention and possession by the Company is in a custodial capacity only. From the related Closing Date, the ownership of each related Mortgage Loan, including the Mortgage Note, the Mortgage, the contents of the related Mortgage File and the related Servicing File and all rights, benefits, proceeds and obligations arising therefrom or in connection therewith, has been vested in the Purchaser.

If the Purchaser makes such examination prior to the related Closing Date and identifies any Mortgage Loans that do not conform to the terms of the related Purchase Price and Terms Letter or the Purchaser’s underwriting standards, such Mortgage Loans may, at the Purchaser’s option, be rejected for purchase by the Purchaser. If not purchased by the Purchaser, such Mortgage Loans shall be deleted from the related Mortgage Loan Schedule. The Purchaser may, at its option and without notice to the Company, purchase all or part of any Mortgage Loan Package without conducting any partial or complete examination. The fact that the Purchaser has conducted or has determined not to conduct any partial or complete examination of the Mortgage Files or Servicing Files shall not affect the Purchaser’s (or any of its successors’) rights to demand repurchase or other relief or remedy provided for in this Agreement.

With respect to UBS Website Mortgage Loans, the Purchaser or the Purchaser’s designee may perform due diligence reviews on the related credit file and legal file relating to such UBS Website Mortgage Loan.

The Purchaser may, at its option, purchase a UBS Website Mortgage Loan without conducting any partial or complete examination.

If the Company is required to repurchase any Mortgage Loan pursuant to this Section 3.03 as a result of a breach of any of the representations and warranties set forth in Section 3.02, the Company may, with the Purchaser’s prior consent, within two (2) years from the related Closing Date, remove such defective Mortgage Loan from the terms of this Agreement and substitute another mortgage loan for such defective Mortgage Loan, in lieu of repurchasing such defective Mortgage Loan. Any substitute Mortgage Loan shall (a) have a principal balance at the time of substitution not in excess of the principal balance of the defective Mortgage Loan (the amount of any difference, plus one month’s interest thereon at the Mortgage Interest Rate borne by the defective Mortgage Loan, being paid by the Company and deemed to be a Principal Prepayment to an account designated by the Purchaser), (b) have a Mortgage Interest Rate not less than, and not more than one percentage point greater than, the Mortgage Interest Rate of the removed Mortgage Loan, (c) have a remaining term to stated maturity not later than, and not more than one year less than, the remaining term to stated maturity of the removed Mortgage Loan, (d) be, in the reasonable determination of the Purchaser, of the same type, quality and character (including location of the Mortgaged Property) as the removed Mortgage Loan as if the breach had not occurred, (e) have a Loan-to-Value Ratio at origination no greater than that of the removed Mortgage Loan, (f) have the same lien priority as that of the removed Mortgage Loan and (g) be, in the reasonable determination of the Purchaser, in material compliance with the representations and warranties contained in this Agreement and described in Section 3.02 as of the date of substitution.

With respect to Mortgage Loans which are not UBS Website Mortgage Loans, the Company shall amend the related Mortgage Loan Schedule to reflect the withdrawal of the removed Mortgage Loan from this Agreement and the substitution of such substitute Mortgage Loan therefor. Upon such amendment, the Purchaser shall review the Mortgage File delivered to it relating to the substitute Mortgage Loan. The Monthly Payment on a substitute Mortgage Loan due on the Due Date in the month of substitution shall be the property of the Company and the Monthly Payment on the defective Mortgage Loan for which the substitution is made due on such date shall be the property of the Purchaser.

Notwithstanding the foregoing, within 90 days of the earlier of discovery by the Company or receipt of notice by the Company of a breach of any representation or warranty by the Company which materially and adversely affects the interests of the Purchaser in any Prepayment Penalty, the Company shall pay the amount of such Prepayment Penalty to the Purchaser.

It is understood and agreed that the obligation of the Company set forth in this Section 3.03 to cure, repurchase or substitute for a defective Mortgage Loan, to pay the amount of certain Prepayment Penalties, and to indemnify Purchaser pursuant to Section 5.01, constitutes the sole remedies of the Purchaser respecting a breach of the foregoing representations and warranties. If the Company fails to repurchase or substitute for a defective Mortgage Loan or pay the amount of a Prepayment Penalty in accordance with this Section 3.03, or fails to cure a defective Mortgage Loan to Purchaser’s reasonable satisfaction in accordance with this Section 3.03, or to indemnify Purchaser pursuant to Section 5.01, that failure shall be an Event of Default and the Purchaser shall be entitled to pursue all available remedies. No provision of this paragraph shall affect the rights of the Purchaser to terminate this Agreement for cause, as set forth in Sections 6.01 and 7.01.

Any cause of action against the Company relating to or arising out of the breach of any representations and warranties made in Sections 3.01 and 3.02 shall accrue as to any Mortgage Loan upon (i) the earlier of discovery of such breach by the Company or notice thereof by the Purchaser to the Company, (ii) failure by the Company to cure such breach or repurchase such Mortgage Loan as specified above, and (iii) demand upon the Company by the Purchaser for compliance with this Agreement.

In the event that any Mortgage Loan is held by a REMIC, notwithstanding any contrary provision of this Agreement, with respect to any Mortgage Loan that is not in default or as to which no default is imminent, Purchaser may, in connection with any repurchase or substitution of a defective Mortgage Loan pursuant to this Section 3.03, require that the Company deliver, at the Company’s expense, an Opinion of Counsel to the effect that such repurchase or substitution will not (i) result in the imposition of taxes on “prohibited transactions” of such REMIC (as defined in Section 860F of the Code) or otherwise subject the REMIC to tax, or (ii) cause the REMIC to fail to qualify as a REMIC at any time.

Section 3.04

Repurchase of Convertible Mortgage Loans.

In the event the Mortgagor under any Convertible Mortgage Loan elects to convert said Mortgage Note to a fixed interest rate Mortgage Note, as provided in said Mortgage Note, then the Company shall, prior to the effective date of said conversion, repurchase such Convertible Mortgage Loan from the Purchaser in accordance with Section 3.03 hereof.

Section 3.05

Repurchase of Mortgage Loans With Early Payment Default.

If the first or second Monthly Payment due after the related Closing Date or any monthly payment due and unpaid as of the Closing Date is not made with thirty days of the date such payment was due, then the Company, at the Purchaser’s option, shall (a) promptly repurchase the related Mortgage Loan (and the Servicing Rights thereto) from the Purchaser in accordance with the procedures set forth in Section 3.03 hereof, however, any such repurchase shall be made at the Repurchase Price, (b) indemnify the Purchaser in accordance with Section 5.01 hereof, or (c) substitute a mortgage loan acceptable to the Purchaser in accordance with Section 3.03 hereof.

Section 3.06

Purchase Price Protection.

With respect to any Mortgage Loan that prepays in full on or prior to the last day of the third full month following the related Closing Date (or such other date set forth in the related Purchase Price and Terms Letter or the UBS Website), the Company shall reimburse the Purchaser an amount equal to the product of (a) the excess of the Purchase Price percentage paid by the Purchaser to the Company for such Mortgage Loan over 100%, times (b) the outstanding principal balance of the Mortgage Loan as of the date of such prepayment in full. Such payment shall be made within thirty (30) days of such payoff. Upon any assignment of a Mortgage Loan and/or this Agreement, the Purchaser may at its option retain its rights under this Section 3.06 notwithstanding such assignment.

Subject to Section 5.02, this Agreement shall inure to the benefit of and be binding upon the Company and the Purchaser and their respective successors and assigns.

Section 9.15

Each of the parties to this Agreement acknowledges that no representations, agreements or promises were made to any of the other parties to this Agreement or any of its employees other than those representations, agreements or promises specifically contained herein, in the related Purchase Price and Terms Letter and the related Assignment and Conveyance, or the UBS Website, as applicable. This Agreement and the related Purchase Price and Terms Letter or the terms of the UBS Website Program set forth the entire understanding between the parties hereto and shall be binding upon all successors of all of the parties. In the event of any inconsistency between the related Purchase Price and Terms Letter or the UBS Website Program and this Agreement, this Agreement shall control.

Section 9.16

No Solicitation.

From and after the related Closing Date, the Company agrees that it will not take any action or permit or cause any action to be taken by any of its agents or affiliates, or by any independent contractors on the Company’s behalf, to personally, by telephone, by mail, or electronically by e-mail or through the internet or otherwise, solicit the borrower or obligor under any Mortgage Loan to refinance the Mortgage Loan, in whole or in part, without the prior written consent of the Purchaser. It is understood and agreed that all rights and benefits relating to the solicitation of any Mortgagors to refinance any Mortgage Loans and the attendant rights, title and interest in and to the list of such Mortgagors and data relating to their Mortgages (including insurance renewal dates) shall be transferred to the Purchaser pursuant hereto on the related Closing Date and the Company shall take no action to undermine these rights and benefits. Notwithstanding the foregoing, it is understood and agreed that promotions undertaken by the Company or any affiliate of the Company which are directed to the general public at large, including, without limitation, mass mailing based on commercially acquired mailing lists, newspaper, radio and television advertisements shall not constitute solicitation under this Section 9.16.

The Company shall use its best efforts to prevent the sale of the name of any Mortgagor to any Person who is not an affiliate of the Company.

Section 9.17

Financial Statements.

The Company understands that in connection with the Purchaser’s marketing of the Mortgage Loans, the Purchaser shall make available to prospective purchasers the Company’s financial statements for the most recently completed three fiscal years respecting which such statements are available. The Company also shall make available any comparable interim statements to the extent any such statements have been prepared by the Company (and are available upon request to members or stockholders of the Company or the public at large). The Company, if it has not already done so, agrees to furnish promptly to the Purchaser copies of the statements specified above. The Company also shall make available information on its servicing performance with respect to loans serviced for others, including delinquency ratios.

The Company also agrees to allow access to knowledgeable financial, accounting, origination and servicing officers of the Company for the purpose of answering questions asked by any prospective purchaser regarding recent developments affecting the Company, its loan origination or servicing practices or the financial statements of the Company.

Section 9.18

Mandatory Delivery; Grant of Security Interest.

The sale and delivery of each Mortgage Loan on or before the related Closing Date is mandatory from and after the date of the execution of the related Purchase Price and Terms Letter or Assignment, Assumption and Recognition Agreement, it being specifically understood and agreed that each Mortgage Loan is unique and identifiable on the date of the related Purchase Price and Terms Letter or UBS Website and that an award of money damages would be insufficient to compensate the Purchaser for the losses and damages incurred by the Purchaser (including damages to prospective purchasers of the Mortgage Loans) in the event of the Company’s failure to deliver each of the related Mortgage Loans or one or more Mortgage Loans otherwise acceptable to the Purchaser on or before the related Closing Date. The Company hereby grants to the Purchaser a lien on and a continuing security interest in each Mortgage Loan and each document and instrument evidencing each such Mortgage Loan to secure the performance by the Company of its obligations hereunder, and the Company agrees that it holds such Mortgage Loans in custody for the Purchaser subject to the Purchaser’s (i) right to reject any Mortgage Loan under the terms of this Agreement and the related Purchase Price and Terms Letter or the UBS Website Program, and (ii) obligation to pay the related Purchase Price for the Mortgage Loans. All rights and remedies of the Purchaser under this Agreement are distinct from, and cumulative with, any other rights or remedies under this Agreement or afforded by law or equity and all such rights and remedies may be exercised concurrently, independently or successively.

Section 9.19

Counterparts.

This Agreement may be executed simultaneously in any number of counterparts. Each counterpart shall be deemed to be an original, and all such counterparts shall constitute one and the same instrument.

Section 9.20

Intention of the Parties.

It is the intention of the parties that the Purchaser is purchasing, and the Company is selling, the Mortgage Loans and not a debt instrument of the Company or another security. Accordingly, the parties hereto each intend to treat the transaction for Federal income tax purposes as a sale by the Company, and a purchase by the Purchaser, of the Mortgage Loans. The Purchaser shall have the right to review the Mortgage Loans and the related Mortgage Files to determine the characteristics of the Mortgage Loans which shall affect the Federal income tax consequences of owning the Mortgage Loans and the Company shall cooperate with all reasonable requests made by the Purchaser in the course of such review.

Section 9.21

Waivers.

No term or provision of this Agreement may be waived or modified unless such waiver or modification is in writing and signed by the party against whom such waiver or modification is sought to be enforced.

Section 9.22

Further Agreements.

The Company and the Purchaser each agree to execute and deliver to the other such reasonable and appropriate additional documents, instruments or agreements as may be necessary or appropriate to effectuate the purposes of this Agreement.

Section 9.23

Costs.

Company shall pay any fees and disbursements of its attorneys and the costs and expenses incurred in connection with the recording of the Assignments of Mortgage (and any other intervening Assignments of Mortgage), and any taxes, governmental assessments, insurance premiums, water, sewer and municipal charges and similar expenses, which became due in respect of the Mortgaged Property on or prior to the related Closing Date. Additionally, all costs and expenses incurred in connection with the transfer and delivery of the Mortgage Loans and related Servicing Rights including, without limitation, any termination fees owed to Company’s document custodian or subservicer, any costs relating to transfer of the Mortgage File or Servicing File and other Mortgage Loan records to Purchaser, the costs of delivering complete master file tape information and other electronically stored information to the Purchaser, the costs of notifying the Mortgagors, hazard, flood and mortgage insurance companies and other third parties as required, Purchaser’s costs for setting up “lifetime” tax service contracts, the costs of transferring “lifetime” flood certification contracts to the Purchaser, and the legal fees and expenses of its attorneys shall be paid by the Company. In the event that the “lifetime” flood certification contracts are not transferable to, or acceptable to, Purchaser, Company will also reimburse Purchaser for any costs related to setting up such flood contracts. Purchaser shall pay any of its expenses, including any fees and disbursements of its attorneys.

Section 9.24

Electronic Execution.

With respect to the UBS Website Mortgage Loans, the Company and the Purchaser hereto agree that each document required to be executed under this Agreement including, without limitation, the Assignment, Assumption and Recognition Agreement, the form of which is set forth on the UBS Website, and it required to be delivered on the Closing Dates shall be executed by the Company and the Purchaser Electronically. The Company and the Purchaser hereby agree that any such electronic executions shall be conclusive evidence of such party’s intent to execute such document, shall be binding on such party and that the other party hereto (in addition to each other third party thereto, if any) is relying on the enforceability of such execution.

IN WITNESS WHEREOF, the Company and the Purchaser have caused their names to be signed hereto by their respective officers thereunto duly authorized as of the day and year first above written.

Re:

Master Seller’s Purchase, Warranties and Interim Servicing Agreement, dated as of May 1, 2005

Gentlemen:

I have acted as counsel to American Home Mortgage Corp., a New York corporation (the “Company”), in connection with the sale of certain loans by the Company to UBS Real Estate Securities Inc. (the “Purchaser”) pursuant to (i) a Master Seller’s Purchase, Warranties and Interim Servicing Agreement, dated as of May 1, 2005 , between the Company and the Purchaser (the “Sale Agreement”) [and the related Purchase Price and Terms Letter, dated ______________, 200_, between the Company and the Purchaser (the “related Purchase Price and Terms Letter”)] and (ii) the UBS Website Program. Capitalized terms not otherwise defined herein have the meanings set forth in the Sale Agreement.

In connection with rendering this opinion letter, I, or attorneys working under my direction have examined, among other things, originals, certified copies or copies otherwise identified to my satisfaction as being true copies of the following:

The Sale Agreement;

[The related Purchase Price and Terms Letter; the Assignment, Assumption and Recognition Agreement;]

The Company’s [Certificate of Incorporation and by-laws] [certificate of limited partnership and limited partnership agreement], as amended to date; and

Resolutions adopted by the Board of Directors of the Company with specific reference to actions relating to the transactions covered by this opinion (the “Board Resolutions”).

For the purpose of rendering this opinion, I have made such documentary, factual and legal examinations as I deemed necessary under the circumstances. As to factual matters, I have relied upon statements, certificates and other assurances of public officials and of officers and other representatives of the Company, and upon such other certificates as I deemed appropriate, which factual matters have not been independently established or verified by me. I have also assumed, among other things, the genuineness of all signatures, the legal capacity of all natural persons, the authenticity of all documents submitted to me as originals, and the conformity to original documents of all documents submitted to me as copies and the authenticity of the originals of such copied documents.

On the basis of and subject to the foregoing examination, and in reliance thereon, and subject to the assumptions, qualifications, exceptions and limitations expressed herein, I am of the opinion that:

The Company has been duly [incorporated] [formed] and is validly existing and in good standing under the laws of the State of __________ with corporate power and authority to own its properties and conduct its business as presently conducted by it. The Company has the corporate power and authority to service the Mortgage Loans, and to execute, deliver, and perform its obligations under the Sale Agreement [and the related Purchase Price and Terms Letter] [and the UBS Website Program] (sometimes collectively, the “Agreements”).

The Sale Agreement [and the related Purchase Price and Terms Letter] [and the Assignment, Assumption and Recognition Agreement] have been duly and validly authorized, executed and delivered by the Company.

The Sale Agreement [and the related Purchase Price and Terms Letter] [and the terms of the UBS Website Program] constitute valid, legal and binding obligations of the Company, enforceable against the Company in accordance with their respective terms.

No consent, approval, authorization or order of any state or federal court or government agency or body is required for the execution, delivery and performance by the Company of the Sale Agreement [and the related Purchase Price and Terms Letter] [and the terms of the UBS Website Program], or the consummation of the transactions contemplated by the Sale Agreement [and the related Purchase Price and Terms Letter], [and the UBS Website Program], except for those consents, approvals, authorizations or orders which previously have been obtained.

Neither the servicing of the Mortgage Loans by the Company as provided in the Sale Agreement [and the related Purchase Price and Terms Letter,] [and the UBS Website Program] nor the fulfillment of the terms of or the consummation of any other transactions contemplated in the Sale Agreement [and the related Purchase Price and Terms Letter] [and the UBS Website Program] will result in a breach of any term or provision of the [certificate of incorporation or by-laws] [certificate of limited partnership or limited partnership agreement] of the Company, or, to the best of my knowledge, will conflict with, result in a breach or violation of, or constitute a default under, (i) the terms of any indenture or other agreement or instrument known to me to which the Company is a party or by which it is bound, (ii) any State of __________ or federal statute or regulation applicable to the Company, or (iii) any order of any State of ________________ or federal court, regulatory body, administrative agency or governmental body having jurisdiction over the Company, except in any such case where the default, breach or violation would not have a material adverse effect on the Company or its ability to perform its obligations under the Sale Agreement.

There is no action, suit, proceeding or investigation pending or, to the best of my knowledge, threatened against the Company which, in my judgment, either in any one instance or in the aggregate, would draw into question the validity of the Sale Agreement or which would be likely to impair materially the ability of the Company to perform under the terms of the Sale Agreement.

The sale of each Note and Mortgage or Pledge Agreement, as applicable, as and in the manner contemplated by the Sale Agreement is sufficient fully to transfer to the Purchaser all right, title and interest of the Company thereto as noteholder and mortgagee.

The opinions above are subject to the following additional assumptions, exceptions, qualifications and limitations:

I have assumed that all parties to the Agreements other than the Company have all requisite power and authority to execute, deliver and perform their respective obligations under each of the Agreements, and that the Agreements have been duly authorized by all necessary corporate action on the part of such parties, have been executed and delivered by such parties and constitute the legal, valid and binding obligations of such parties.

My opinion expressed in paragraphs 3 and 7 above is subject to the qualifications that (i) the enforceability of the Agreements may be limited by the effect of laws relating to (1) bankruptcy, reorganization, insolvency, moratorium or other similar laws now or hereafter in effect relating to creditors’ rights generally, including, without limitation, the effect of statutory or ether laws regarding fraudulent conveyances or preferential transfers, and (2) general principles of equity upon the specific enforceability of any of the remedies, covenants or other provisions of the Agreements and upon the availability of injunctive relief or other equitable remedies and the application of principles of equity (regardless of whether such enforceability is considered in a proceeding in equity or at law) as such principles relate to, limit or affect the enforcement of creditors’ rights generally and the discretion of the court before which any proceeding for such enforcement may be brought; and (ii) I express no opinion herein with respect to the validity, legality, binding effect or enforceability of provisions for indemnification in the Agreements to the extent such provisions may be held to be unenforceable as contrary to public policy.

I have assumed, without independent check or certification, that there are no agreements or understandings among the Company, the Purchaser and any other party which would expand, modify or otherwise affect the terms of the documents described herein or the respective rights or obligations of the parties thereunder.

I am admitted to practice in the State of ________________ and I render no opinion herein as to matters involving the laws of any jurisdiction other than the State of ____________ and the Federal laws of the United States of America.

Very truly yours,

RE: ABC Bank:

Dear Valued Member:

At ABC Bank we are committed to providing premier customer service and are always looking for ways to serve you better. We are happy to announce that your mortgage with ABC Bank which is currently being serviced by ABC Bank, will now be serviced by our state-of-the-art facility in Ewing, New Jersey effective June 1, 2004. We are confident that you will be pleased with this upgrade in service. Enclosed in this letter is all of the pertinent information with regards to the changes in the servicing of your loan.

You will receive a separate mortgage statement each month with a coupon attached. It will also include recent activity, current escrow and loan balances. Additionally, you will have online access to your mortgage information at ▇▇▇.▇▇▇▇▇▇▇.▇▇▇ as well as enhanced call center operations.

We ask that you note two changes that will directly affect your mortgage loan:

1) You will have a new loan number; and

2) We will have a new mailing address for mortgage transactions.

Your new loan number is above, and our new mailing address for your payments will be printed on the coupon attached to each monthly statement. For your records, please note this new address is for your mortgage payment only:

ABC Bank

▇▇ ▇▇▇ ▇▇▇

▇▇▇▇▇▇, ▇▇▇ ▇▇▇▇▇▇ ▇▇▇▇▇-▇▇▇▇

Please address all other mortgage related correspondence to:

ABC Bank

▇▇ ▇▇▇ ▇▇▇▇▇

▇▇▇▇▇, ▇▇▇ ▇▇▇▇▇▇ ▇▇▇▇▇

Enclosed herewith please find a temporary ▇▇▇▇ for mailing your June payment. If you are currently using a coupon book with your payments, you may discard it after your May payment has been sent.

If your monthly payment is automatically deducted from your checking/savings account, this service will continue without interruption. However, for the month of June, if your normal drafting date is between June 1^st and June 15^th, your payment will be deducted on or about June 15^th. You will not be penalized in any way by this timing difference. All future drafting dates will be unaffected by this change. If sufficient funds are not available in your checking/savings account at the time of your scheduled draft date no second attempt to draft will occur. You also may be charged a fee for non-sufficient funds. Your payment will need to be mailed to the address previously provided and no additional drafts will occur until your account is made current.

If you would like to begin using our automatic deduction service, please complete the enclosed authorization form and return it with a voided check or encoded deposit slip to the address indicated on the form. Because of the required lead time to set up automatic deduction, it will be necessary for you to continue mailing your payments until you are notified when your drafting will begin.

If you are currently making your mortgage payment through a third-party entity like ▇▇▇▇-pay or government allotment, you will need to advise them of your new loan number and change the payee information to ABC Bank ▇.▇. ▇▇▇ ▇▇▇, ▇▇▇▇▇▇, ▇▇▇ ▇▇▇▇▇▇ ▇▇▇▇▇-▇▇▇▇.

Please contact your last known homeowners’ insurance company and ask that your “mortgagee” clause be updated to read:

ABC Bank

Its successors and/or assigns

c/o Central Loan Administration & Reporting

(i)

P. O. ▇▇▇ ▇▇▇▇ ▇▇▇▇▇▇▇▇▇▇▇▇, ▇▇ ▇▇▇▇▇-▇▇▇▇

If ABC Bank holds your escrow account, please send any future real estate tax bills to: ABC Bank ▇.▇. ▇▇▇ ▇▇▇▇▇▇, ▇▇▇▇▇▇, ▇▇ ▇▇▇▇▇ and property insurance bills to: ABC Bank ▇.▇. ▇▇▇ ▇▇▇▇, ▇▇▇▇▇▇▇▇▇▇▇▇, ▇▇ ▇▇▇▇▇-▇▇▇▇. Please include your new mortgage loan account number on all correspondence.

You will receive two (2) Year-End Statements for 2004. One (1) will reflect payment and disbursement activity for the period of time ABC Bank serviced your loan and the other will be from ABCD Bank and it will reflect payment and disbursement activity from the transfer date through the end of the year.

Prior to June 1, 2004 if you have any questions about the changes we are making, please contact ABC Bank Customer Service Representatives at:

XXX-XXX-XXXX

After June 1, 2004, the new toll free number you will use to access a mortgage representative or for automated mortgage information our 24-hours/7 days/week automated telephone access service is:

XXX-XXX-XXXX

This change does not affect any other terms or conditions of your mortgage document.

We would like to thank you for choosing ABC Bank for your mortgage financing. We are confident that you will continue to receive the same high quality service that you have been accustomed to receiving. If you have any questions during this transition, please do not hesitate to contact us.

Sincerely,

ABC Bank

RE: ABC Bank Loan Number:

ABCD Bank Loan Number:

Dear Valued Customer:

We would like to thank you for your mortgage loan business and notify you that ABC Bank will be changing some aspects of how we service your mortgage loan. The most notable change is that previously you knew our mortgage servicing operation as ABC Bank, a division of ABC Bank. Beginning May 1, 2001, all services will be provided under the name of ABCD Bank.

The other processing changes that become effective May 1, 2001 are as follows:

1. If you choose to mail in your mortgage payment please use the attached coupon when making your payment on or after May 1, 2001. Since your mortgage loan number has changed it is important that you use the new coupon when making your May 2001 payment. Please destroy your old ABC Bank coupons. You will receive your new coupon book in about 30 to 45 days after receiving this letter. Your check should be made payable and mailed to:

Section 9.27

ABC Bank

▇▇ ▇▇▇ ▇▇▇

▇▇▇▇▇▇▇ ▇.▇▇

▇▇▇▇▇▇, ▇▇▇ ▇▇▇▇▇▇ ▇▇▇▇▇-▇▇▇▇

2. If your monthly payment is automatically deducted from your checking account, this service will continue without interruption. However, for the month of May, if your normal drafting date is between May 1^st and May 9^th, your payment will be deducted on or about May 10. All future drafting dates will be unaffected by this change.

3. If you currently make your mortgage payment at a ABC Bank branch or through ABC Bank telephone banking, those payment options will not be available to you after April 30, 2001. However, there are other convenient options for making your mortgage loan payments.

4. If you would like to begin using our automatic deduction service, please complete the enclosed authorization form and return it with a voided check or pre-coded deposit slip to the address indicated on the previous page. When you select this option you have the added convenience of picking your payment date (any day between the 1^st and the 10^th of each month). Because of the required lead time to set up automatic deduction it will be necessary for you to make your May, 2001 payment using the attached coupon and mailing it to the address in #1 on the previous page. If sufficient funds are not available in your checking account you may be charged a $30.00 fee for non-sufficient funds.

5. If you currently make your payments using ABC Bank Online ▇▇▇▇ ▇▇▇▇▇ service you can continue to do so; however, you will need to add ABC Bank to your merchant list and pay your mortgage loan using the ▇▇▇▇ payment function rather than the account transfer function. If you choose this option the required merchant name and new account number information can be found on the attached payment coupons.

Future real estate tax bills should be mailed to: ABC Bank, ▇.▇. ▇▇▇ ▇▇▇▇▇, ▇▇▇▇▇, ▇▇ ▇▇▇▇▇, and property insurance bills should be mailed to: ABC Bank, ▇.▇. ▇▇▇ ▇▇▇▇, ▇▇▇▇▇▇▇▇▇▇▇▇, ▇▇ ▇▇▇▇▇-▇▇▇▇. Please remember to include your new mortgage loan account number on all correspondence.

After May 1, 2001 you will have 24 hours/7 days/week on-line access to more information about your mortgage than ever before. For information about on-line access please visit our web site at (insert URL for website) for complete details.

EXHIBIT E - RESPA TEXT

You should also be aware of the following information, which is set out in more detail in Section 6 of the Real Estate Settlement Procedures Act (RESPA) (12 U.S.C. 2605):

During the 60-day period following the effective date of the transfer of the loan servicing, a loan payment received by your old servicer before its due date may not be treated by the new loan servicer as late, and a late fee may not be imposed on you.

Section 6 of RESPA (12 U.S.C. 2605) gives you certain consumer rights. If you send a “qualified written request” to your loan servicer concerning the servicing of your loan, your servicer must provide you with a written acknowledgment within 20 Business Days of receipt of your request. A “qualified written request” is written correspondence other than notice on a coupon or other payment medium supplied by the servicer, which includes your name and account number, and your reason for the request. If you want to send a “qualified written request” regarding the servicing of your loan, it must be sent to the corresponding address referenced previously.

Not later than 60 Business Days after receiving your request, your loan servicer must make any appropriate corrections to your account, and must provide you with a written clarification regarding any dispute. During the 60 Business Day period, your servicer may not provide information to a consumer reporting agency concerning any overdue payment related to such period or qualified written request. However, this does not prevent the servicer from initiating foreclosure if proper grounds exist under the mortgage documents.

A Business Day is any day on which the offices of the business entity are open to the public for carrying on substantially all of its business functions. Section 6 of RESPA also provides for damages and costs for individuals or classes of individuals in circumstances where servicers are shown to have violated the requirements of that Section. You should seek advice if you believe your rights have been violated.

*Never apply barcode stickers to box lids, tops or sides. If you are unsure about label or sticker placement call (▇▇▇) ▇▇▇-▇▇▇▇ and ask for Customer Service.

ASI containers will accommodate letter or legal size files and should be packed accordingly.

Creating and Submitting an Index of the Box Content

The employee who packed the box then completes an online Electronic Archiving Form (See Attached.)

Required fields Preparer’s Name (your name), Barcode number, SELLER LOAN NUMBER, UBS Loan Number and the date sent.

Once the QC check is completed, if everything is correct then the employee e-mails the completed EAF to a dedicated e-mail box at ASI (▇▇▇▇▇▇▇▇▇▇▇▇▇▇▇@▇▇▇▇▇▇▇▇▇▇▇▇▇▇.▇▇▇). This informs ASI which boxes will arrive at ASI offsite storage facility.

The Seller needs to identify themselves as a Seller of mortgage loans for a Cenlar-UBS relationship as well as when the boxes should be expected to arrive (tracking information pertaining the boxes is also encouraged).

Each box and its corresponding EAF must have a barcode sticker/number before the EAF is e-mailed to ASI and the Record Coordinator before the box is shipped.

A hard copy of the EAF should be placed within the box so ASI can conduct a secondary QC upon arrival.

Employees should also e-mail their completed EAFs to their contact at UBS.
