	(i) The Company has filed with the Securities and Exchange Commission (the “Commission”) a registration statement (No. 333-120922) on Form S-3 for the registration of Commercial Mortgage Pass Through Certificates, issuable in series, including the Underwritten Certificates, under the Securities Act of 1933, as amended (the “1933 Act”), which registration statement has become effective and a copy of which, as amended to the date hereof, has heretofore been delivered to you. The Company meets the requirements for use of Form S-3 under the 1933 Act, and such registration statement, as amended at the date hereof, meets the requirements set forth in Rule 415(a)(1)(x) under the 1933 Act and complies in all other material respects with the 1933 Act and the rules and regulations thereunder. The Company proposes to file with the Commission, with your consent, pursuant to Rule 424 under the 1933 Act, a supplement dated March 18, 2005 (the “Prospectus Supplement”) to the prospectus dated March 18, 2005 (the “Base Prospectus”), relating to the Underwritten Certificates and the method of distribution thereof, and has previously advised you of all further information (financial and other) with respect to the Underwritten Certificates and the Mortgage Pool to be set forth therein. Such registration statement (No. 333-120922), including all exhibits thereto, is referred to herein as the “Registration Statement”; and the Base Prospectus and the Prospectus Supplement, together with any amendment thereof or supplement thereto authorized by the Company prior to the Closing Date for use in connection with the offering of the Underwritten Certificates, are hereinafter called the “Prospectus”. Any preliminary form of the Prospectus Supplement that has heretofore been filed pursuant to Rule 424 or, prior to the effective date of the Registration Statement, pursuant to Rule 402(a) or 424(a), is hereinafter called a “Preliminary Prospectus Supplement”. If so stated in the Prospectus Supplement, the Company will file with the Commission within fifteen days of the issuance of the Underwritten Certificates a report on Form 8-K (“8-K”) setting forth specific information concerning the Mortgage Pool and the Underwritten Certificates to the extent that such information is not set forth in the Prospectus Supplement. As used herein, “Pool Information” means the mortgage pool information reflected in the Master Tape and the Prospectus Supplement. The “Master Tape” shall mean the compilation of information and data regarding the Mortgage Loans covered by the letters rendered by KPMG LLP (a “hard copy” of which Master Tape was produced on behalf of the Mortgage Loan Sellers) described in Section 6(h)(ii) in this Agreement.

	(ii) As of the date hereof, as of the date on which the Prospectus Supplement is first filed pursuant to Rule 424 under the 1933 Act, as of the date on which, prior to the Closing Date, any amendment to the Registration Statement becomes effective, as of the date on which any supplement to the Prospectus Supplement is filed with the Commission, and as of the Closing Date, (i) the Registration Statement, as amended as of any such time, and the Prospectus, as amended or supplemented as of any such time, complies and will comply in all material respects with the applicable requirements of the 1933 Act and the rules and regulations thereunder, (ii) the Registration Statement, as amended as of any such time, does not include and will not include any untrue statement of a m aterial fact and does not omit and will not omit to

	(iii) The Company has been duly incorporated and is validly existing as a corporation in good standing under the laws of the State of North Carolina with corporate power and authority to own, lease or operate its properties and to conduct its business as now conducted by it and to enter into and perform its obligations under this Agreement and the Pooling and Servicing Agreement; and the Company is duly qualified as a foreign corporation to transact business and is in good standing in each jurisdiction in which such qualification is required, whether by reason of the ownership or leasing of property or the conduct of business.

	(iv) As of the date hereof, as of the date on which the Prospectus Supplement is first filed pursuant to Rule 424 under the 1933 Act, as of the date on which, prior to the Closing Date, any amendment to the Registration Statement becomes effective, as of the date on which any supplement to the Prospectus Supplement is filed with the Commission, and as of the Closing Date, there has not and will not have been (i) any request by the Commission for any further amendment to the Registration Statement or the Prospectus or for any additional information, (ii) any issuance by the Commission of any stop order suspending the effectiveness of the Registration Statement or the institution or threat of any proceeding for that purpose or (iii) any notification with respect to the suspension of the qualification of the Underwritten Certificates for sale in any jurisdiction or any initiation or threat of any proceeding for such purpose.

	(v) Each of this Agreement, the Pooling and Servicing Agreement and each Mortgage Loan Purchase Agreement has been duly authorized, executed and delivered by the Company and each of this Agreement, the Pooling and Servicing Agreement, and each Mortgage Loan Purchase Agreement constitutes legal, valid and binding agreements of the Company, enforceable against the Company in accordance with their respective terms, except as enforceability may be limited by (i) bankruptcy, insolvency, reorganization, receivership, moratorium or other similar laws affecting the enforcement of the rights of creditors generally, (ii) general principles of equity, whether enforcement is sought in a proceeding in equity or at law, and (iii) public policy considerations underlying the securities laws, to the extent that such public policy considerations limit the enforceability of the provisions of this Agreement, the Pooling and Servicing Agreement or any Mortgage Loan Purchase Agreement that purport to provide indemnification from securities law liabilities.

-4-

	(vi) As of the Closing Date, the Underwritten Certificates, the Pooling and Servicing Agreement and the Mortgage Loan Purchase Agreements will conform in all material respects to the respective descriptions thereof contained in the Prospectus. As of the Closing Date, the Underwritten Certificates will be duly and validly authorized and, when delivered in accordance with the Pooling and Servicing Agreement to you against payment therefor as provided herein, will be duly and validly issued and outstanding and entitled to the benefits of the Pooling and Servicing Agreement.

	(vii) The Company is not in violation of its certificate of incorporation or by laws or in default under any agreement, indenture or instrument the effect of which violation or default would be material to the Company or which violation or default would have a material adverse affect on the performance of its obligations under this Agreement, the Pooling and Servicing Agreement or any Mortgage Loan Purchase Agreement. Neither the issuance and sale of the Underwritten Certificates, nor the execution and delivery by the Company of this Agreement, any Mortgage Loan Purchase Agreement or the Pooling and Servicing Agreement nor the consummation by the Company of any of the transactions herein or therein contemplated, nor compliance by the Company with the provisions hereof or thereof, did, does or will conflict with or result in a breach of any term or provision of the certificate of incorporation or by laws of the Company or conflict with, result in a breach, violation or acceleration of, or constitute a default (or an event which, with the passing of time or notification, or both, would constitute a default) under, the terms of any indenture or other agreement or instrument to which the Company is a party or by which it or any material asset is bound, or any statute, order or regulation applicable to the Company of any court, regulatory body, administrative agency or governmental body having jurisdiction over the Company.

	(viii) There is no action, suit or proceeding against the Company pending, or, to the knowledge of the Company, threatened, before any court, arbitrator, administrative agency or other tribunal (i) asserting the invalidity of this Agreement, the Pooling and Servicing Agreement, any Mortgage Loan Purchase Agreement or the Underwritten Certificates, (ii) seeking to prevent the issuance of the Underwritten Certificates or the consummation of any of the transactions contemplated by this Agreement, (iii) that might materially and adversely affect the performance by the Company of its obligations under, or the validity or enforceability of, this Agreement, the Pooling and Servicing Agreement, any Mortgage Loan Purchase Agreement or the Underwritten Certificates or (iv) seeking to affect adversely the federal income tax attributes of the Underwritten Certificates as described in the Prospectus.

	(ix) There are no contracts, indentures or other documents of a character required by the 1933 Act or by the rules and regulations thereunder to be described or referred to in the Registration Statement or the Prospectus or to be filed as exhibits to the Registration Statement which have not been so described or referred to therein or so filed or incorporated by reference as exhibits thereto.

	(x) No authorization, approval or consent of any court or governmental authority or agency is necessary in connection with the offering or sale of the Underwritten Certificates pursuant to this Agreement, except such as have been, or as

-5-

	of the Closing Date will have been, obtained or such as may otherwise be required under applicable state securities laws in connection with the purchase and offer and sale of the Underwritten Certificates by the Underwriters and any recordation of the respective assignments of the Mortgage Loans to the Trustee pursuant to the Pooling and Servicing Agreement that have not been completed.

	(xi) The Company possesses all material licenses, certificates, authorities or permits issued by the appropriate state, federal or foreign regulatory agencies or bodies necessary to conduct the business now operated by it, and the Company has not received any notice of proceedings relating to the revocation or modification of any such license, certificate, authority or permit which, singly or in the aggregate, if the subject of any unfavorable decision, ruling or finding, would materially and adversely affect the condition, financial or otherwise, or the earnings, business affairs or business prospects of the Company.

	(xii) Any taxes, fees and other governmental charges in connection with the execution and delivery of this Agreement and the delivery and sale of the Underwritten Certificates (other than such federal, state and local taxes as may be payable on the income or gain recognized therefrom) have been or will be paid at or prior to the Closing Date.

	(xiii) Neither the Company nor the Trust Fund is, and neither the sale of the Underwritten Certificates in the manner contemplated by the Prospectus nor the activities of the Trust Fund pursuant to the Pooling and Servicing Agreement will cause the Company or the Trust Fund to be, an “investment company” or under the control of an “investment company” as such terms are defined in the Investment Company Act of 1940, as amended (the “Investment Company Act”).

	(xiv) Under generally accepted accounting principles (“GAAP”) and for federal income tax purposes, the Company reported the transfer of the Mortgage Loans to the Trustee in exchange for the Certificates and will report the sale of the Underwritten Certificates to the Underwriters pursuant to this Agreement as a sale of the interests in the Mortgage Loans evidenced by the Underwritten Certificates. The consideration received by the Company upon the sale of the Underwritten Certificates to the Underwriters will constitute reasonably equivalent value and fair consideration for the Underwritten Certificates. The Company will be solvent at all relevant times prior to, and will not be rendered insolvent by, the sale of the Underwritten Certificates to the Underwriters. In addition, the Company was solvent at all relevant times prior to, and was not rendered insolvent by, the transfer of the Mortgage Loans to the Trustee on behalf of the Trust Fund. The Company is not selling the Underwritten Certificates to the Underwriters and did not transfer the Mortgage Loans to the Trustee on behalf of the Trust Fund with any intent to hinder, delay or defraud any of the creditors of the Company.

	(xv) At the Closing Date, the respective classes of Underwritten Certificates shall continue to have maintained ratings no lower than those set forth in Schedule I hereto by the nationally recognized statistical rating organizations identified in Schedule I hereto (individually and collectively, the “Rating Agency”).

(b) Each Underwriter may prepare and provide to prospective investors certain Computational Materials, ABS Term Sheets, Structural Term Sheets or Collateral Term Sheets in connection with its offering of the Certificates, subject to the following conditions:

	(i) Such Underwriter shall comply with the requirements of the no action letter, dated May 20, 1994, issued by the Commission to ▇▇▇▇▇▇, ▇▇▇▇▇▇▇ Acceptance Corporation I, ▇▇▇▇▇▇, ▇▇▇▇▇▇▇ & Co.

	(ii) For purposes hereof, “Computational Materials” shall have the meaning given such term in the No Action Letters, but shall include only (x) the Computational Materials attached hereto as Exhibit A and (y) such other Computational Materials that have been delivered to prospective investors by or at the direction of such

-9-

	Underwriter. For purposes hereof, “ABS Term Sheets,” “Structural Term Sheets” and “Collateral Term Sheets” shall have the meanings given such terms in the PSA Letter but shall include only (x) the Term Sheets attached hereto as Exhibit B, and (y) those other ABS Term Sheets, Structural Term Sheets or Collateral Term Sheets that have been prepared for and delivered to prospective investors by or at the direction of such Underwriter.

	(iii) All Computational Materials and Term Sheets provided to prospective investors shall bear a legend in a form previously approved by the Company or its counsel.

	(iv) Such Underwriter shall not distribute any such Computational Materials or Term Sheets unless the forms and methodology thereof are in accordance with this Agreement. Such Underwriter shall provide to the Company, for filing on Form 8-K as provided in Section 5(g), copies (in such format as required by the Company) of all Computational Materials and Term Sheets delivered by such Underwriter. The Underwriter may provide copies of the foregoing in a consolidated or aggregated form including all information required to be filed. All Computational Materials and Term Sheets described in this subsection (iv) must be provided to the Company (a) in paper or electronic format suitable for filing with the Commission and (b) not later than 10:00 a.m. (New York City time) on a business day that is not less than one business day before filing thereof is required pursuant to the terms of the No Action Letters.

If any Computational Materials or Term Sheets were based on assumptions with respect to the Mortgage Pool that differ from the final Pool Information in any material respect or on Underwritten Certificate structuring assumptions (except in the case of Computational Materials when the different structuring terms were hypothesized and so described) that were revised in any material respect prior to the printing of the Prospectus, then to the extent that it has not already done so, such Underwriter shall immediately inform the Company and, upon the direction of the Company, and if not corrected by the Prospectus, shall prepare revised Computational Materials and Term Sheets, as the case may be, based on the final collateral information and structuring assumptions, circulate such revised Computational Materials and Term Sheets to all recipients of the preliminary versions thereof, and include such revised Computational Materials and Term Sheets (marked, “as revised”) in the materials delivered to the Company pursuant to subsection (iv) above.

	(vi) If, within the period during which the Prospectus relating to the Underwritten Certificates is required to be delivered under the 1933 Act, any Computational Materials or Term Sheets are determined, in the reasonable judgment of the Company or such Underwriter, to contain a material error or, when read together with

-10-

	the Prospectus, a material omission, then (unless the material error or omission was corrected in the Prospectus) the Underwriter shall prepare a corrected version of such Computational Materials or Term Sheets, shall circulate such corrected Computational Materials or Term Sheets to all recipients of the prior versions thereof, and shall deliver copies of such corrected Computational Materials or Term Sheets (marked, “as corrected”) to the Company for filing with the Commission in a subsequent Form 8-K submission (subject to the Company’s obtaining an accountant’s comfort letter in respect of such corrected Computational Materials and Term Sheets, which shall be at the expense of such Underwriter).

	(viii) In the event of any delay in the delivery by such Underwriter to the Company of all Computational Materials and Term Sheets required to be delivered in accordance with subsection (iv) above, the Company shall have the right to delay the release of the Prospectus to investors or to the Underwriter, to delay the Closing Date and to take other appropriate actions in each case as necessary in order to allow the Company to comply with its agreement set forth in Section 5(g) to file the Computational Materials and Term Sheets by the time specified therein.

	(ix) Computational Materials and Term Sheets may be distributed by the Underwriter through electronic means in accordance with SEC Release No. 33-7233 or other applicable laws or regulations.

(c) Each Underwriter further agrees that it shall promptly provide the Company with such pricing information as the Company may reasonably request to enable it to comply with its reporting requirements with respect to each class of Underwritten Certificates to the extent such information can in the good faith judgment of the Underwriter be reasonably determined by it.

5. Covenants of the Company. The Company covenants and agrees with the Underwriters that:

(a) The Company will not file any amendment to the Registration Statement (other than by reason of Rule 429 under the 1933 Act) or any supplement to the Base Prospectus relating to or affecting the Underwritten Certificates, unless the Company has furnished a copy to you for your review a reasonable time prior to filing, and will not file any such proposed amendment or supplement to which you reasonably object. Subject to the foregoing sentence, the Company will cause the Prospectus Supplement to be transmitted to the Commission for filing pursuant to Rule 424 under the 1933 Act or will cause the Prospectus Supplement to be filed with the Commission pursuant to said Rule 424. The Company promptly will advise you or counsel for the Underwriters (i) when the Prospectus Supplement shall have been filed or

-11-

(i) against any and all loss, liability, claim, damage and expense whatsoever, as incurred, arising out of any untrue statement or alleged untrue statement of a material fact contained in the Registration Statement (or any amendment thereto), or the omission or alleged omission therefrom of a material fact required to be stated therein or necessary to make the statements therein not misleading or arising out of any untrue statement or alleged untrue statement of a material fact contained in the Base Prospectus, any Preliminary Prospectus Supplement or the Prospectus Supplement (or any amendment or supplement thereto), or the omission or alleged omission therefrom of a material fact necessary in order to make the statements therein, in the light of the circumstances under which they were made, not misleading; provided the foregoing indemnity shall not inure to the benefit of any Underwriter (or to the benefit of any person controlling such Underwriter) from whom the person asserting claims giving rise to any such losses, claims, damages, expenses or liabilities purchased Underwritten Certificates if such untrue statement or omission or alleged untrue statement or omission made in any Preliminary Prospectus Supplement or Prospectus is eliminated or remedied in the Prospectus or a corrected and amended Prospectus as applicable, and, if required by law, a copy of the Prospectus (as corrected or amended, if applicable) shall not have been sent to such person at or prior to the written confirmation of the sale of such Underwritten Certificates to such person unless such failure to deliver the Prospectus (as corrected or amended, if applicable) was a result of the Company’s failure to furnish copies thereof in sufficient quantity or the Company’s failure to deliver copies thereof in such reasonable time period that would have allowed the Underwriter to provide the Prospectus (as corrected or amended, if applicable) to such person at or prior to the written confirmation of the sale of such Certificates to such person; provided, however,

-20-

	that the indemnity provided by this Section 8(a) shall not apply to any loss, liability, claim, damage or expense to the extent any such untrue statement or alleged untrue statement or omission or alleged omission arises out of or is based upon an untrue statement or omission with respect to information with respect to which a Mortgage Loan Seller provides indemnification pursuant to Section 7 of each of the related Mortgage Loan Purchase Agreements (the “Mortgage Loan Seller Covered Information”); provided, further, that, the indemnification provided by this Section 8 shall not apply to the extent that such untrue statement or omission of a material fact was made as a result of an error in the manipulation of, or in any calculations based upon, or in any aggregation of the information regarding the Mortgage Loans, the related Mortgagors and/or the related Mortgaged Properties set forth in the Master Tape or Annex A to the Prospectus Supplement or Preliminary Prospectus Supplement, to the extent (i) such information was materially incorrect in the Master Tape or such Annex A, as applicable, including without limitation the aggregation of such information relating to the Mortgage Loans in the Trust Fund or the information provided by the related Mortgage Loan Sellers, and (ii) such loss, liability, claim, damage or expense would be subject to the provisions of Section 7 of the related Mortgage Loan Purchase Agreements;

	(ii) against any and all loss, liability, claim, damage and expense whatsoever, as incurred, to the extent of the aggregate amount paid in settlement of any litigation, or any investigation or proceeding by any governmental agency or body, commenced or threatened, or of any claim whatsoever based upon any such untrue statement or omission, or any such alleged untrue statement or omission, if such settlement is effected with the written consent of the Company or as otherwise contemplated by Section 8(c); and

	(iii) against any and all expense whatsoever, as incurred (including the fees and disbursements of counsel chosen by such Underwriter), reasonably incurred in investigating, preparing or defending against any litigation, or any investigation or proceeding by any governmental agency or body, commenced or threatened, or any claim whatsoever based upon any such untrue statement or omission, or any such alleged untrue statement or omission, to the extent that any such expense is not paid under (i) or (ii) above; provided, however, that the indemnity provided by this Section 8(a) shall not apply to any loss, liability, claim, damage or expense to the extent arising out of any untrue statement or omission or alleged untrue statement or omission made in reliance upon and in conformity with written information (as specified in Section 8(b) below) furnished to the Company by any Underwriter expressly for use in the Registration Statement (or any amendment thereto) or in the Base Prospectus, any Preliminary Prospectus Supplement or the Prospectus Supplement (or any amendment or supplement thereto).

(b) Each Underwriter, severally but not jointly, agrees to indemnify and hold harmless the Company, its directors, each of its officers who signed the Registration Statement, and each person, if any, who controls the Company within the meaning of Section 15 of the 1933 Act or Section 20 of the 1934 Act, against any and all loss, liability, claim, damage and expense described in the indemnity contained in subsection (a) of this Section, as incurred, but only with respect to untrue statements or omissions, or alleged untrue statements or omissions, made in the

-21-

Registration Statement (or any amendment thereto) or in the Base Prospectus, any Preliminary Prospectus Supplement or the Prospectus Supplement (or any amendment or supplement thereto) in reliance upon and in conformity with written information furnished to the Company by such Underwriter expressly for use in the Registration Statement (or any amendment thereto) or in the Base Prospectus, such Preliminary Prospectus Supplement or the Prospectus Supplement (or any amendment or supplement thereto); provided, that no such material misstatement or omission arises from an error or omission in information relating to the underlying data regarding the Mortgage Loans or the related Mortgagors or Mortgaged Properties provided by the Company or any Mortgage Loan Seller to such Underwriter. In addition, each Underwriter, severally but not jointly, shall indemnify and hold harmless the Company, its directors, each of its officers who signed the Registration Statement and each person, if any, who controls the Company within the meaning of either Section 15 of the 1933 Act or Section 20 of the 1934 Act, against any and all losses, liabilities, claims and damages as incurred arising out of any untrue statement or alleged untrue statement of a material fact or omission or alleged omission of a material fact contained in any Term Sheets or Computational Materials which, when read together with any Preliminary Prospectus Supplement and the Prospectus Supplement (or any amendment or supplement thereto), was required to be stated therein or necessary to make the statements therein not misleading; provided, that no such material misstatement or omission arises from an error or omission in information relating to the underlying data regarding the Mortgage Loans or the related Mortgagors or Mortgaged Properties provided by the Company or any Mortgage Loan Seller to such Underwriter; and provided, further, that any such Term Sheets or Computational Materials were prepared and distributed by such Underwriter. Notwithstanding the foregoing, the indemnity in the immediately preceding sentence will apply only if such misstatement or omission was not also a misstatement or omission in the Prospectus. It is hereby acknowledged that (i) the statements set forth in the first, second, third, fourth and fifth sentences of the penultimate paragraph on the cover of the Prospectus Supplement, (ii) the statements in the second paragraph and the first sentence of the sixth paragraph under the caption “Method of Distribution” in the Prospectus Supplement, and (iii) the statements in any Computational Materials and Term Sheets prepared and delivered by the Underwriters to the Company for filing (subject to the other provisions of this Section (b)) with the Commission pursuant to this Agreement and the No Action Letters, constitute the only written information furnished to the Company by the Underwriters expressly for use in the Registration Statement (or any amendment thereto) or in the Base Prospectus, the Preliminary Prospectus Supplement or the Prospectus Supplement (or any amendment or supplement thereto).

(c) Each indemnified party shall give notice as promptly as reasonably practicable to each indemnifying party of any action commenced against it in respect of which indemnity may be sought hereunder, but failure to so notify an indemnifying party shall not relieve such indemnifying party from any liability under Section 8(a) or Section 8(b) hereof (unless the indemnifying party is materially prejudiced by such failure) or any liability that it may have, otherwise than on account of the indemnity provided by this Section 8. An indemnifying party may participate at its own expense in the defense of any such action and, to the extent that it may elect by written notice delivered to the indemnified party promptly after receiving the aforesaid notice from the indemnified party, to assume the defense thereof, with counsel satisfactory to such indemnified party. In any such proceeding, any indemnified party shall have the right to retain its own counsel, but the fees and expenses of such counsel shall be at the expense of such indemnified party unless (i) the indemnifying party and the indemnified

-22-

party shall have agreed to the retention of such counsel, or (ii) the indemnifying party shall not have assumed the defense of such action, with counsel satisfactory to the indemnified party, within a reasonable period following the indemnifying party’s receiving notice of such action, or (iii) the named parties to any such proceeding (including any impleaded parties) include both the indemnifying party and the indemnified party and representation of both parties by the same counsel would be inappropriate due to actual or potential differing interests between them. In no event shall the indemnifying party or parties be liable for fees and expenses of more than one counsel (or, in the event the Company or Wachovia is the indemnifying party, one counsel for each Underwriter) (in addition to any local counsel) separate from its or their own counsel for all indemnified parties in connection with any one action or separate but similar or related actions in the same jurisdiction arising out of the same general allegations or circumstances. Unless it shall assume the defense of any proceeding, an indemnifying party shall not be liable for any settlement of any proceeding effected without its written consent (which consent shall not be unreasonably withheld) but, if settled with such consent or if there be a final judgment for the plaintiff, the indemnifying party shall indemnify the indemnified party from and against any loss or liability by reason of such settlement or judgment. Notwithstanding the foregoing sentence, if at any time an indemnified party shall have requested an indemnifying party to reimburse the indemnified party for fees and expenses of counsel or any other expenses for which the indemnifying party is obligated under this subsection, the indemnifying party agrees that it shall be liable for any settlement of any proceeding effected without its written consent if (i) such settlement is entered into more than 45 days after receipt by such indemnifying party of the aforesaid request and (ii) such indemnifying party shall not have reimbursed the indemnified party in accordance with such request prior to the date of such settlement. If an indemnifying party assumes the defense of any proceeding, it shall be entitled to settle such proceeding with the consent of the indemnified party or, if such settlement provides for an unconditional release of the indemnified party in connection with all matters relating to the proceeding that have been asserted against the indemnified party in such proceeding by the other parties to such settlement, which release does not include a statement as to or an admission of fault, culpability or a failure to act by or on behalf of any indemnified party without the consent of the indemnified party.

(d) The indemnity provided by this Section 8 shall remain operative and in full force and effect regardless of (i) any termination of this Agreement, (ii) any investigation made by the Company, the Underwriters, any of their respective directors or officers, or any person controlling the Company or the Underwriters, and (iii) acceptance of and payment for any of the Underwritten Certificates.

(e) Each Underwriter, severally but not jointly, will indemnify and hold harmless any other Underwriter and each person, if any, who controls such Underwriter within the meaning of either the 1933 Act or the 1934 Act (collectively, the “Non Indemnifying Underwriter”) from and against any and all loss, liability, claim, damage and expense whatsoever, as incurred, that arise out of or are based upon (i) any untrue statement or alleged untrue statement of a material fact or omission or alleged omission of a material fact contained in Computational Materials or Term Sheets (other than the Computational Materials and Term Sheets attached hereto as Exhibit A and Exhibit B) which, when read together with any Preliminary Prospectus Supplement and the Prospectus Supplement, was required to be stated therein or necessary to make the statements therein not misleading prepared by such indemnifying Underwriter or any member of its selling group, in connection with the

-23-

Underwritten Certificates (or in any revision or amendment thereof or supplement thereto) or (ii) the failure of such indemnifying Underwriter, or any member of its selling group, to comply with any provision of Section 4(b) hereof, and agrees to reimburse each such Non Indemnifying Underwriter, as incurred, for any legal or other expenses reasonably incurred by them in connection with investigating or defending any such loss, liability, claim, damage or expense; provided, that the indemnity provided by this Section 8(e) shall not apply to the extent that such indemnified Underwriter is entitled under any Mortgage Loan Purchase Agreement to seek indemnity for such loss, liability, claim, damage or expense from a Mortgage Loan Seller affiliated with the Underwriter seeking indemnification.

The indemnity provided by this Section 8 will be in addition to any liability that any Underwriter, the Company or Wachovia may otherwise have.

9. Contribution.

(a) In order to provide for just and equitable contribution in circumstances in which the indemnity provided by Section 8 hereof is for any reason held to be unenforceable by the indemnified parties although applicable in accordance with its terms, or if such indemnification provided for in Section 8 hereof is insufficient in respect of any losses, liabilities, claims or damages referred to therein, the Company and Wachovia, jointly and severally, and the Underwriters, severally, shall contribute to the aggregate losses, liabilities, claims, damages and expenses of the nature contemplated by the indemnity provided by Section 8 incurred by the Company and the Underwriters, as incurred, (i) in such proportion as is appropriate to reflect the relative benefits received by the Company and Wachovia on the one hand and each Underwriter on the other from the offering of the Underwritten Certificates or (ii) if the allocation provided by clause (i) above is not permitted by applicable law, in such proportion as is appropriate to reflect not only the relative benefits referred to in clause (i) above but also the relative fault of the Company and Wachovia on the one hand and of each Underwriter on the other in connection with the statements or omissions which resulted in such losses, claims, damages, expenses or liabilities, as well as any other relevant equitable considerations (taking into account the parties’ relative knowledge and access to information concerning the matter with respect to which the claim was asserted, the opportunity to correct and prevent any statement or omission or failure to comply, and any other equitable considerations appropriate under the circumstances). The relative benefits received by the Company and Wachovia on the one hand and the Underwriters on the other shall be deemed to be in the same respective portions as the net proceeds (before deducting expenses) received by the Company from the sale of the Underwritten Certificates and the total underwriting discounts and commissions and other fees received by the Underwriters in connection therewith bear to the aggregate offering price of the Underwritten Certificates. The relative fault of the Company and Wachovia on the one hand and of each Underwriter on the other shall be determined by reference to, among other things, whether the untrue or alleged untrue statement of a material fact or the omission or alleged omission to state a material fact relates to information supplied by the Company and Wachovia or by the Underwriters, and the parties’ relative intent, knowledge, access to information and opportunity to correct or prevent such statement or omission. Notwithstanding the foregoing, no person guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the 1933 Act) shall be entitled to contribution from any person who was not guilty of such fraudulent misrepresentation; and no Underwriter shall be obligated to

-24-

contribute more than its share of underwriting discounts and commissions and other fees pertaining to the Underwritten Certificates less any damages otherwise paid by such Underwriter with respect to such loss, liability, claim, damage or expense. It is hereby acknowledged that the respective Underwriters’ obligations under this Section 9 shall be several and not joint. For purposes of this Section, each person, if any, who controls an Underwriter within the meaning of Section 15 of the 1933 Act or Section 20 of the 1934 Act, and such Underwriter’s officers and directors, shall have the same rights to contribution as such Underwriter, and each director of the Company, each officer of the Company who signed the Registration Statement, and each person, if any, who controls the Company within the meaning of Section 15 of the 1933 Act or Section 20 of the 1934 Act shall have the same rights to contribution as the Company.

(b) The parties hereto agree that it would not be just and equitable if contribution were determined by pro rata or per capita allocation or by any other method of allocation that does not take account of the considerations referred to in subsection (a) above. The amount paid or payable by an indemnified party as a result of the losses, liabilities, claims or damages referred to in Section 8 or this Section 9 shall be deemed to include any legal fees and disbursements or other expenses reasonably incurred by such indemnified party in connection with investigating or defending any such claim except where the indemnified party is required to bear such expenses, which expenses the indemnifying party shall pay as and when incurred, at the request of the indemnified party, to the extent that it is reasonable to believe that the indemnifying party will be ultimately obligated to pay such expenses. In the event that any expenses so paid by the indemnifying party are subsequently determined to not be required to be borne by the indemnifying party hereunder, the party which received such payment shall promptly refund the amount so paid to the party which made such payment. The remedies provided for in Section 8 and this Section 9 are not exclusive and shall not limit any rights or remedies that may otherwise be available to any indemnified party at law or in equity.

(c) The contribution agreements contained in this Section 9 shall remain operative and in full force and effect regardless of (i) any termination of this Agreement, (ii) any investigation made by the Company, the Underwriters, any of their respective directors or officers, or any person controlling the Company or the Underwriters, and (iii) acceptance of and payment for any of the Underwritten Certificates.

10. Default by an Underwriter. If any one or more Underwriters shall fail to purchase and pay for any of the Underwritten Certificates agreed to be purchased by such Underwriter or Underwriters hereunder and such failure to purchase shall constitute a default in the performance of its or their obligations under this Agreement, the remaining Underwriters shall be obligated severally (in the respective proportions which the portion of the Underwritten Certificates set forth opposite their names in Schedule II hereto bears to the aggregate amount of Underwritten Certificates set forth opposite the names of all the remaining Underwriters) to purchase the Underwritten Certificates that the defaulting Underwriter or Underwriters agreed but failed to purchase; provided, that no Underwriter shall be obligated under this Section 10 to purchase Certificates of a Class that it is not otherwise obligated to purchase under this Agreement, and provided, however, that in the event that the amount of Underwritten Certificates that the defaulting Underwriter or Underwriters agreed but failed to purchase shall exceed 10% of the aggregate principal amount of Underwritten Certificates set forth in Schedule II hereto, the remaining Underwriters shall have the right to purchase all, but shall not be under

-25-

any obligation to purchase any, of the Underwritten Certificates, and if such nondefaulting Underwriters do not purchase all of the Underwritten Certificates, this Agreement will terminate without liability to any nondefaulting Underwriter or the Company, except as provided in Section 11 or Section 12. In the event of a default by any Underwriter as set forth in this Section 10, the Closing Date for the Underwritten Certificates shall be postponed for such period, not exceeding ten business days, as you shall determine in order that the required changes in the Registration Statement and the Prospectus Supplement or in any other documents or arrangements may be effected. Nothing contained in this Agreement shall relieve any defaulting Underwriter of its liability, if any, to the Company and any nondefaulting Underwriter for damages occasioned by its default hereunder.

11. Representations, Warranties and Agreements to Survive Delivery. All representations, warranties and agreements contained in this Agreement, or contained in certificates of officers of the Company and Wachovia submitted pursuant hereto, shall remain operative and in full force and effect, regardless of any investigation made by or on behalf of any Underwriter, or by or on behalf of the Company and Wachovia, or by or on behalf of any of the controlling persons and officers and directors referred to in Sections 8 and 9, and shall survive delivery of the Underwritten Certificates to the Underwriters.

12. Termination of Agreement; Survival.

(a) The Underwriters may terminate this Agreement, by notice to the Company, at any time at or prior to the Closing Date (i) if there has been, since the date of this Agreement or since the respective dates as of which information is given in the Registration Statement and the Prospectus, any material adverse change in the condition, financial or otherwise, or in the earnings, business affairs or business prospects of the Company or of Wachovia whether or not arising in the ordinary course of business, or (ii) if there has occurred any outbreak of hostilities or escalation thereof or other calamity or crisis the effect of which is such as to make it, in the reasonable judgment of any Underwriter, impracticable or inadvisable to market the Underwritten Certificates or to enforce contracts for the sale of the Underwritten Certificates, or (iii) if trading in any securities of the Company or of Wachovia has been suspended or limited by the Commission or the New York Stock Exchange, or if trading generally on the American Stock Exchange or the New York Stock Exchange or on the Nasdaq National Market has been suspended or limited, or minimum or maximum prices for trading have been fixed, or maximum ranges for prices have been required, by any of said exchanges or by such system or by order of the Commission, the National Association of Securities Dealers, Inc. or any other governmental authority, or (iv) if a banking moratorium has been declared by either federal or New York authorities, or (v) a material disruption in securities, settlement, payments or clearance services in the United States or other relevant jurisdiction shall have occurred.

(b) If this Agreement is terminated pursuant to this Section, such termination shall be without liability of any party to any other party, except as provided in Section 11 or Section 12(c).

-26-

(c) The provisions of Section 5(e) regarding the payment of costs and expenses and the provisions of Sections 8 and 9 hereof shall survive the termination of this Agreement, whether such termination is pursuant to this Section 12 or otherwise.
