(iii) On the effective date of the Registration Statement, the Registration Statement conformed in all material respects with the applicable requirements of the Act and the Rules and Regulations, and did not include any untrue statement of a material fact or omit to state any material fact required to be stated therein or necessary to make the statements therein not misleading and, on the Closing Date, the Registration Statement and on the date hereof and on the Closing Date the Prospectus will conform in all material respects with the applicable requirements of the Act and the Rules and Regulations, and (x) the Registration Statement will not include any untrue statement of a material fact or omit to state any material fact required to be stated therein or necessary to make the statements therein not misleading and (y) the Prospectus will not contain any untrue statement of a material fact or omit to state a material fact required to be stated therein or necessary to make the statements therein, in light of the circumstances under which they were made, not misleading; provided, however, that the foregoing does not apply to (I) that part of the Registration Statement which constitutes the

The Seller or COAF, as applicable, has, in all material respects, full power and authority to execute, deliver and perform its obligations under this Underwriting Agreement and each Transaction Document to which it is a party, own its properties and conduct its business as described in the Prospectus, is duly qualified to do business and is in good standing (or is exempt from such requirements), and has obtained all necessary material licenses and approvals (except with respect to the state securities or Blue Sky laws of various jurisdictions), in each jurisdiction in which failure to so qualify or obtain such licenses and approvals would have a material adverse effect on the interests of holders of the Notes. The Seller has full power and authority to cause the Issuer to issue the Notes.

(c) The execution, delivery and performance by the Seller or COAF, as applicable, of this Underwriting Agreement and each Transaction Document to which it is a party, and the issuance and sale of the Notes, and the consummation of the transactions contemplated hereby and thereby, have been duly authorized by all necessary limited liability company or corporate action on the part of the Seller or COAF, respectively. Neither the execution and delivery by the Seller or COAF, as applicable, of such instruments, nor the performance by the Seller or COAF, respectively, of the transactions herein or therein contemplated, nor the compliance by the Seller or COAF, as applicable, with the provisions hereof or thereof, will (i) conflict with or result in a breach of any of the terms and provisions of, or constitute a default under, any of the provisions of the limited liability company agreement, certificate of formation, Articles of Incorporation or By-laws, as applicable, of such entity, (ii) result in a material conflict with any of the provisions of any judgment, decree or order binding on the Seller or COAF, as applicable, or its properties, (iii) conflict with any of the provisions of any material indenture, mortgage, agreement, contract or other instrument to which the Seller or COAF, as applicable, is a party or by which it is bound, (iv) conflict with, contravene or constitute a violation of any law, statute, ordinance, rule or regulation to which it is subject, or (v) result in the creation or imposition of any lien, charge or encumbrance upon any of the Seller’s or COAF’s, as applicable, property pursuant to the terms of any such indenture, mortgage, contract or other instrument.

(g) Any taxes, fees and other governmental charges in connection with the execution, delivery and performance by the Seller or COAF of this Underwriting Agreement and each Transaction Document to which it is a party shall have been paid or will be paid by the Seller or COAF, as applicable, at or before the Closing Date to the extent then due.

(h) The Notes, when validly issued pursuant to the Indenture and sold to the Underwriters pursuant to this Underwriting Agreement will conform in all material respects to the descriptions thereof contained in the Prospectus and will be validly issued and entitled to the benefits and security afforded by the Indenture.

Upon the authorization by the Representatives of the release of the Notes, each Underwriter proposes to offer the Notes for sale upon the terms and conditions set forth in the Prospectus. If the Prospectus specifies an initial public offering price or a method by which the price at which such Notes are to be sold, then after the Notes are released for sale to the public, the Underwriters may vary from time to time the public offering price, selling concessions and reallowances to dealers that are members of the National Association of Securities Dealers, Inc. (“NASD”) and other terms of sale hereunder and under such selling arrangements.

(b) Notwithstanding the foregoing, each Underwriter agrees that it will not offer or sell any Notes within the United States, its territories or possession or to persons who are citizens thereof or residents therein, except in transactions that are not prohibited by any applicable securities, bank regulatory or other applicable law.

(i) it has not offered or sold, and prior to the date which is six months after the Closing Date, will not offer or sell any Notes to persons in the United Kingdom except to persons whose ordinary activities involve them in acquiring, holding, managing, or disposing of investments (as principal or agent) for the purposes of their businesses or otherwise in circumstances which have not resulted and will not result in an offer to the public in the United Kingdom within the meaning of the Public Offers of Securities Regulations 1995, as amended (the “Regulations”) and the Financial Services and Markets Xxx 0000, as amended (the “FSMA”);

(ii) it has only communicated or caused to be communicated and will only communicate or cause to be communicated any invitation or inducement to

engage in investment activity (within the meaning of Section 21 of the FSMA received by it in connection with the issue or sale of any Notes in circumstances in which Section 21(1) of the FSMA does not apply to the Issuer and shall procure that the Notes are not offered or sold in the United Kingdom other than to persons authorised under the FSMA or to persons otherwise having professional experience in matters relating to investments and qualifying as investment professionals under Article 19 of the Financial Services and Markets Xxx 0000 (Financial Promotion) Order 2001, as amended or to persons qualifying as high net worth persons under Article 49 of that Order or, if distributed in the United Kingdom by authorised persons, only to persons qualifying as investment professionals under Article 14 of the Financial Services and Markets Xxx 0000 (Promotion of Collective Investment Schemes) (Exemptions) Order 2001 (“CIS Order”) or to persons qualifying as high net worth persons under Article 22 of the CIS Order or to any other person to whom the Notes may otherwise lawfully be offered or to whom such invitation or inducement to engage in investment activity in connection with the issue or sale of the Notes may otherwise lawfully be communicated or caused to be communicated; and

(iii) it has complied and will comply with all applicable provisions of the Regulations and the FSMA with respect to anything done by it in relation to the Notes in, from or otherwise involving the United Kingdom.

Section 5. Covenants.

The Seller or COAF, as the case may be, covenants and agrees with each Underwriter that:

(a) The Seller will prepare a prospectus supplement (the “Prospectus Supplement”) setting forth the amount of Notes covered thereby and the terms thereof not otherwise specified in the Prospectus, the price at which the Notes are to be purchased by the Underwriters from the Seller, the initial public offering price at which the Notes are to be sold, the selling concessions and allowances, if any, and such other information as the Seller deems appropriate in connection with the offering of the Notes, but the Seller will not file any amendments to the Registration Statement as in effect with respect to the Notes, or any amendments or supplements to the Prospectus, without the Representatives’ prior consent (which consent shall not be unreasonably withheld or delayed); the Seller will immediately advise the Representatives and their counsel: (i) when notice is received from the Commission that any post-effective amendment to the Registration Statement has become or will become effective and (ii) of any order or communication suspending or preventing, or threatening to suspend or prevent, the offer and sale of the Notes or of any proceedings or examinations that may lead to such an order or communication, whether by or of the Commission or any authority administering any state securities or Blue Sky law, as soon as practicable after the Seller is advised thereof, and will use its reasonable efforts to prevent the issuance of any such order or communication and to obtain as soon as possible its lifting, if issued.

(b) Within the time period during which a prospectus relating to the Notes is required to be delivered under the Act, the Seller will comply with all requirements imposed upon it by the Act and by the Rules and Regulations, as from time to time in force, so far as necessary to permit the continuance of sales of or dealings in the Notes, as contemplated by the provisions hereof and the Prospectus. If, at any time when a Prospectus relating to the Notes is required to be delivered under the Act, any event occurs as a result of which the Prospectus as then amended or supplemented would include any untrue statement of a material fact or omit to state any material fact necessary to make the statements therein, in light of the circumstances under which they were made, not misleading, or if it is necessary at any time to amend or supplement the Prospectus to comply with the Act or the Rules and Regulations, the Seller will promptly prepare and (subject to review and consent by the Representatives as described in Section 5(a)) file with the Commission, an amendment or supplement that will correct such statement or omission or an amendment that will effect such compliance; provided, however, that the Representatives’ consent to any amendment shall not constitute a waiver of any of the conditions of Section 6.

(c) The Seller will make (or will cause the Issuer to make) generally available to the holders of the Notes (the “Noteholders”) (the sole Noteholders being the applicable clearing agency in the case of Book-Entry Notes), in each case as soon as practicable, a statement which will satisfy the provisions of Section 11 (a) of the Act and Rule 158 of the Commission with respect to the Notes.

(d) The Seller will furnish to the Representatives copies of the Registration Statement (at least one copy to be delivered to the Representatives will be conformed and will include all documents and exhibits thereto or incorporated by reference therein), the Prospectus, and all amendments and supplements to such documents, in each case as soon as available and in such quantities as the Representatives may reasonably request.

(e) The Seller will assist the Underwriters in arranging for the qualification of the Notes for sale and the determination of their eligibility for investment under the laws of such jurisdictions as the Representatives may designate and will continue to assist the Underwriters in maintaining such qualifications in effect so long as required for the distribution; provided, however, that neither the Seller nor the Issuer shall be required to qualify to do business in any jurisdiction where it is now not qualified or to take any action which would subject it to general or unlimited service of process in any jurisdiction in which it is now not subject to service of process or to file a general consent to service of process in any jurisdiction in which it is now not subject to service of process.

(f) If filing of the Prospectus or any portion thereof is required under Rule 424(b) of the Commission, the Seller will file the Prospectus, properly completed, and any supplement thereto, pursuant to Rule 424(b) within the prescribed time period and will provide evidence satisfactory to the Representatives of such timely filing.

(g) So long as any of the Notes are outstanding, the Seller or COAF, as applicable, will furnish to the Underwriters, by first-class mail, as soon as practicable: (i) all documents required to be distributed to the Noteholders; and (ii) from time to time, such other information concerning the Seller, COAF or the Issuer as the Underwriters may reasonably request.

(h) The Seller and COAF will apply the net proceeds from the sale of the Notes as set forth in the Prospectus.

(i) On or before the final transfer of Subsequent Receivables to the Issuer and the expiration of the Pre-Funding Period, if COAF is required by the Note Insurer to obtain a letter from Ernst & Young LLP, as independent auditors for COAF, to the effect that such accountants have performed certain specified procedures, all of which have been agreed to by COAF, as a result of which they have determined, having examined in accordance with such agreed-upon procedures, that the Subsequent Receivables conform to the related requirements described in the Prospectus, COAF shall deliver a copy of such letter, addressed to the Representatives. The foregoing letter shall be at the expense of COAF.

(j) At the time of the execution and delivery of each subsequent transfer, the Subsequent Receivables will have been duly and validly assigned to the Indenture Trustee in accordance with the Indenture; and when such assignment is effected, a duly and validly perfected transfer of all such Subsequent Receivables subject to no prior lien, mortgage, security interest, pledge charge or other encumbrance created by COAF or the Seller will have occurred. As of the related Funding Date, each of the Subsequent Receivables will meet the eligibility criteria described in the Prospectus.

The obligations of the Underwriters to purchase and pay for the Notes will be subject to the accuracy of the representations and warranties on the part of the Seller and COAF herein as of the date hereof and the Closing Date, to the accuracy of the representations and warranties of the Issuer contained in each Transaction Document to which it is a party as of the Closing Date, to the accuracy of the statements of the Seller and COAF made pursuant to the provisions thereof, to the performance by the Seller and COAF in all material respects of their respective obligations hereunder and to the following additional conditions precedent:

all its obligations hereunder may be canceled at, or at any time before, the Closing Date by the Representatives. Notice of such cancellation shall be given to the Issuer, the Seller and COAF in writing or by telephone or facsimile confirmed in writing.

Section 7. Expenses.

(a) Except as expressly set forth in this Underwriting Agreement, COAF and the Seller, jointly and severally, will pay all expenses incidental to the performance of its obligations hereunder and will reimburse each Underwriter for any expense reasonably incurred by it in connection with (i) the qualification of the Notes and determination of their eligibility for investment under the laws of such jurisdictions as the Representatives may designate (including the reasonable fees and disbursements of their counsel), (ii) the printing of memoranda relating thereto, (iii) any fees charged by credit rating agencies for the rating of the Notes, and (iv) expenses incurred in distributing the Prospectus (including any amendments and supplements thereto) to the Underwriters. Except as specifically provided in this Section 7 and in Section 8 of this Underwriting Agreement, each Underwriter will pay all of its own costs and expenses (including the fees and disbursements of counsel), transfer taxes on resales of Notes by it and any advertising expenses connected with any offers it may make.

(b) If the sale of the Notes provided for herein is not consummated because any condition to the obligations of the Underwriters set forth in Section 6 is not satisfied or because of any refusal, inability or failure on the part of the Seller or COAF to perform any agreement herein or to comply with any provision hereof other than by reason of a default by any Underwriter, the Seller and COAF will reimburse the Underwriters upon demand for all out-of-pocket expenses (including reasonable fees and disbursements of counsel) that shall have been incurred by the Underwriters in connection with the proposed purchase, sale and offering of the Notes. Neither the Seller nor COAF shall be liable to the Underwriters for loss of anticipated profits from the transactions covered by this Underwriting Agreement.

Section 8. Indemnification and Contribution.

(a) The Seller and COAF, jointly and severally, will indemnify and hold harmless each Underwriter and each person, if any, who controls any Underwriter within the meaning of the Act or the Exchange Act and the respective officers, directors and employees of each such person, against any losses, claims, damages or liabilities, joint or several, to which such Underwriter or such controlling person may become subject, under the Act, the Exchange Act or otherwise, insofar as such losses, claims, damages or liabilities (or actions in respect thereof) arise out of or are based upon any untrue statement or alleged untrue statement of any material fact contained in the Registration Statement, the Prospectus or any amendment or supplement thereto, or any related preliminary prospectus, or arise out of or are based upon the omission or alleged omission to state therein a material fact required to be stated therein or necessary to make the statements therein not misleading; and will reimburse each Underwriter and each such officer, director, employee or controlling person for any legal or other expenses reasonably incurred by each Underwriter through the Representatives and each such officer, director, employee or controlling person in connection with investigating or defending any such loss, claim, damage, liability or action; provided, however, that (i) neither the Seller nor COAF

will be liable in any such case to the extent that any such loss, claim, damage or liability arises out of or is based upon any such untrue statement or alleged untrue statement in or omission or alleged omission made in any such documents in reliance upon and in conformity with written information furnished to the Seller by any Underwriter specifically for use therein, it being understood and agreed that the only such information is that described as such in Section 8(b) hereof, and (ii) neither the Seller nor COAF shall be liable to any Underwriter to the extent that any such loss, claim, damage or liability of such Underwriter arises as a result of a misstatement or omission or alleged misstatement or omission in the Preliminary Prospectus that was corrected in the Prospectus (and copies of which Prospectus were furnished to such Underwriter) and such Underwriter, if required by law, failed to give or send to the purchaser, at or before the written confirmation of sale, a copy of the Prospectus. This indemnity agreement will be in addition to any liability which the Seller or COAF may otherwise have.

(b) Each Underwriter, severally and not jointly, will indemnify and hold harmless the Seller and COAF, and each person, if any, who controls the Seller or COAF within the meaning of the Act or the Exchange Act and the respective officers, directors, and employees of each such person, against any losses, claims, damages or liabilities to which the Seller or COAF may become subject, under the Act, the Exchange Act or otherwise, insofar as such losses, claims, damages or liabilities (or actions in respect thereof) arise out of or are based upon any untrue statement or alleged untrue statement of any material fact contained in the Registration Statement, the Prospectus, or any amendment or supplement thereto, or any related preliminary prospectus, or arise out of or are based upon the omission or the alleged omission to state therein a material fact required to be stated therein or necessary to make the statements therein not misleading, in each case to the extent, but only to the extent, that such untrue statement or alleged untrue statement or omission or alleged omission was made in reliance upon and in conformity with written information furnished to the Seller or COAF by such Underwriter through the Representatives specifically for use therein, and will reimburse any legal or other expenses reasonably incurred by the Seller or COAF, and each such officer, director, employee or controlling person, as the case may be, in connection with investigating or defending any such loss, claim, damage, liability or action. Each of the Seller and COAF agrees with each Underwriter that the only information furnished to the Seller and COAF by the Underwriters specifically for use in the Registration Statement, the Prospectus, or any amendment or supplement thereto, or any related preliminary prospectus, is the information set forth in the second paragraph (regarding concessions and discounts) and the second sentence of the ninth paragraph (regarding market making) under the caption “Underwriting” in the Prospectus Supplement. This indemnity agreement will be in addition to any liability that each Underwriter may otherwise have.

(c) Promptly after receipt by an indemnified party under this Section of notice of the commencement of any action, such indemnified party will, if a claim in respect thereof is to be made against the indemnifying party under clause (a) or (b) of this Section 8, notify the indemnifying party of the commencement thereof, but the omission and/or delay so to notify the indemnifying party shall not relieve it from any liability which it may have to any indemnified party other than under clause (a) or (b) of this Section 8. In case any such action is brought against any indemnified party, and it notifies the indemnifying party of the commencement thereof, the indemnifying party will be entitled to participate therein and, to the extent that it may

elect by written notice, jointly with any other indemnifying party similarly notified, to assume the defense thereof, with counsel reasonably satisfactory to such indemnified party (who shall not, except with the consent of the indemnified party be counsel to the indemnifying party), and after notice from the indemnifying party to such indemnified party of its election so to assume the defense thereof, the indemnifying party will not be liable to such indemnified party under this Section for any legal or other expenses (including fees and expenses of counsel) subsequently incurred by such indemnified party in connection with defense thereof other than reasonable costs of investigation. If the defendants in any action include both the indemnified party and the indemnifying party and the indemnified party shall have reasonably concluded that there may be legal defenses available to it and/or other indemnified parties that are different from or additional to those available to the indemnifying party, the indemnified party or parties shall have the right to select separate counsel reasonably satisfactory to the indemnifying party to assert such legal defenses and to otherwise participate in the defense of such action on behalf of such indemnified party or parties. No indemnifying party shall, without the prior written consent of the indemnified party, effect any settlement of any pending or threatened action in respect of which any indemnified party is or could have been a party and indemnity could have been sought hereunder by such indemnified party unless such settlement includes an unconditional release of such indemnified party from all liability on any claims that are the subject matter of such action. The indemnifying party shall not be liable for any settlement of any proceeding effected without its written consent, but if settled with such consent or if there be a final judgment for the plaintiff, the indemnifying party agrees to indemnify any indemnified party from and against any loss or liability by reason of such settlement or judgment.

(d) If the indemnification provided for in this Section 8 is unavailable or insufficient to hold harmless an indemnified party under subsection (a) or (b) of this Section 8, then such indemnifying party shall contribute to the amount paid or payable by such indemnified party as a result of the losses, claims, damages or liabilities referred to in this Section, (i) in such proportion as is appropriate to reflect the relative benefits received by the Seller and COAF on the one hand and relevant Underwriter on the other from the offering of the Notes or (ii) if the allocation provided by clause (i) is not permitted by applicable law, in such proportion as is appropriate to reflect not only the relative benefits referred to in clause (i) but also the relative fault of the Seller and COAF on the one hand and the relevant Underwriter on the other in connection with the statements or omissions which resulted in such losses, claims, damages or liabilities as well as any other relevant equitable considerations. The relative benefits received by the Seller and COAF on the one hand and the relevant Underwriter on the other shall be deemed to be in the same proportion as the total net proceeds from the offering (before deducting expenses) collectively received by the Seller and COAF bear to the total underwriting discounts and commissions received by the relevant Underwriter. The relative fault 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 Seller, COAF or by any Underwriter and the parties’ relative intent, knowledge, access to information and opportunity to correct or prevent such untrue statement or omission. The amount paid by an indemnified party as a result of the losses, claims, damages or liabilities referred to in the first sentence of this clause (d) shall be deemed to include any legal or other expenses reasonably incurred by such indemnified party in connection with investigating or defending any action or claim (which shall be limited as provided in subsection (c) above if the indemnifying

party has assumed the defense of any such action in accordance with the provisions thereof) which is the subject of this clause (d). Notwithstanding the provisions of this clause (d), no Underwriter shall be required to contribute any amount in excess of the amount by which the total price at which such Notes underwritten by such Underwriter and distributed to the public were offered to the public exceeds the amount of any damages which such Underwriter has otherwise been required to pay by reason of such untrue or alleged untrue statement or omission or alleged omission. No person guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the Act) shall be entitled to contribution from any person who was not guilty of such fraudulent misrepresentation. The obligation of the Underwriters under this Section 8(d) shall be several in proportion to their respective underwriting obligations and not joint.

(e) The obligations of the indemnifying party under this Section shall be in addition to any liability which the indemnifying party may otherwise have and shall extend, upon the same terms and conditions, to each person, if any, who controls the indemnifying party within the meaning of the Act.

Section 9. Survival of Representations and Obligations.

The respective agreements, representations, warranties and other statements made by the Seller and COAF or their officers, including any such agreements, representations, warranties and other statements relating to the Issuer, and of the Underwriters set forth in or made pursuant to this Underwriting Agreement will remain in full force and effect, regardless of any investigation, or statement as to the results thereof, made by or on behalf of the Underwriters, the Seller, COAF or any of their respective officers or directors or any controlling person, and will survive delivery of and payment of the Notes. The provisions of Section 7 and Section 8 shall survive the termination or cancellation of this Underwriting Agreement.

Section 10. Notices.

All communications hereunder shall be in writing and effective only on receipt, and, if to the Representatives or the Underwriters, will be mailed, delivered or faxed and confirmed to: Credit Suisse First Boston LLC, 00 Xxxxxxx Xxxxxx, 0^xx Xxxxx, Xxx Xxxx, Xxx Xxxx 00000, facsimile: (000) 000-0000, Attention: Xxxx Xxxxxxxxx; if sent to the Seller, will be mailed, delivered or faxed and confirmed to Capital One Auto Receivables, LLC, 0000 Xxxxxxx Xxx Xxxxx, XxXxxx, Xxxxxxxx 00000, Attention: Director of Capital Markets, with a copy to the General Counsel, and if sent to COAF, will be mailed, delivered or faxed and confirmed to: Capital One Auto Finance, Inc., 0000 Xxxxxxx Xxx Xxxxx, XxXxxx, Xxxxxxxx 00000, Attention: Director of Capital Markets, with a copy to the General Counsel.

Section 11. Applicable Law, Entire Agreement.

This Underwriting Agreement will be governed by and construed in accordance with the law of the State of New York. This Underwriting Agreement supersedes all prior agreements and understandings relating to the subject matter hereof.

Section 12. Successors.

This Underwriting Agreement will inure to the benefit of and be binding upon the parties hereto and their respective successors and the officers, directors and controlling persons referred to in Section 8 hereof, and their successors and assigns, and no other person will have any right or obligation hereunder.

Section 13. Waivers; Headings.

Neither this Underwriting Agreement nor any term hereof may be changed, waived, discharged or terminated orally, but only by an instrument in writing signed by the party against whom enforcement of the change, waiver, discharge or termination is sought. The headings in this Underwriting Agreement are for purposes of reference only and shall not limit or otherwise affect the meaning hereof.

Section 14. Termination of the Obligations of the Underwriters.

The obligations of the Underwriters to purchase the Notes on the Closing Date shall be terminable by the Representatives by written notice delivered to the Seller and COAF if at any time on or before the Closing Date: (a) trading in securities generally on the New York Stock Exchange shall have been suspended or materially limited, or there shall have been any setting of minimum prices for trading on such exchange, (b) a general moratorium on commercial banking activities in New York, Texas or Virginia shall have been declared by any of Federal, New York state, Texas state or Virginia state authorities, (c) there shall have occurred an outbreak or escalation of hostilities or a declaration by the United States of a national emergency or war or any other major act of terrorism involving the United States, or any other substantial national or international calamity, emergency or crisis, the effect of which on the financial markets of the United States is such as to make it, in the reasonable judgment of the Representatives, impracticable or inadvisable to market the Notes on the terms and in the manner contemplated in the Prospectus, or (d) any change or any development involving a prospective change, materially and adversely affecting (i) the Trust Estate taken as a whole or (ii) the business or properties of the Seller or COAF occurs, which, in the reasonable judgment of the Representatives, in the case of either clause (i) or (ii), makes it impracticable or inadvisable to market the Notes on the terms and in the manner contemplated in the Prospectus. Upon such notice being given, the parties to this Underwriting Agreement shall (except for the liability of the Seller and COAF under Section 7 and Section 8 and the liability of each Underwriter under Section 16) be released and discharged from their respective obligations under this Underwriting Agreement.

Section 15. Representation of Underwriters.

The Representatives will act for the several Underwriters in connection with this Underwriting Agreement, and any action by the Representatives under this Underwriting Agreement will be binding upon all of the Underwriters.

Section 16. Default by an Underwriter.

If any one or more Underwriters shall fail to purchase and pay for any of the Notes 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 Underwriting Agreement, the remaining Underwriters shall be obligated severally to take up and pay for (in the respective proportions which the amount of Notes set forth opposite their names on Annex I hereto bears to the aggregate amount of Notes set forth opposite the names of all the remaining Underwriters) the Notes which the defaulting Underwriter or Underwriters agreed but failed to purchase; provided, however, that if the aggregate amount of Notes which the defaulting Underwriter or Underwriters agreed but failed to purchase shall exceed 25% of the aggregate principal amount of Notes set forth on Annex I hereto, the remaining Underwriters shall have the right to purchase all, but shall not be under any obligation to purchase any, of the Notes, and if such nondefaulting Underwriters do not purchase all the Notes, this Underwriting Agreement will terminate without liability to any nondefaulting Underwriter, the Seller or COAF. In the event of a default by any Underwriter as set forth in this Section 16, the Closing Date shall be postponed for such period as is mutually agreeable to COAF, the Seller and the Representatives (with all parties hereto agreeing that time is of the essence) in order that the required changes in the Registration Statement and the Prospectus (and any supplements thereto) or in any other documents or arrangements may be effected. Nothing contained in this Underwriting Agreement shall relieve any defaulting Underwriter of its liability, if any, to the Seller, COAF and any nondefaulting Underwriter for damages occasioned by its default hereunder.

Section 17. Computational Materials, ABS Term Sheets and Electronic Copy of Preliminary Prospectus.

(a) Each Underwriter represents and warrants to the Issuer, COAF and the Seller that it has not and will not use any information that constitutes “Computational Materials,” as defined in the Commission’s No-Action Letter, dated May 20, 1994, addressed to Xxxxxx, Xxxxxxx Acceptance Corporation I, Xxxxxx, Peabody & Co. Incorporated and Xxxxxx Structured Asset Corporation (as made generally applicable to registrants, issuers and underwriters by the Commission’s response to the request of the Public Securities Association dated May 27, 1994), with respect to the offering of the Notes.

(b) Each Underwriter represents and warrants to the Issuer, COAF and the Seller that it has not and will not use any information that constitutes “ABS Term Sheets,” as defined in the Commission’s No-Action Letter, dated February 13, 1995, addressed to the Public Securities Association, with respect to the offering of the Notes.

(c) Each Underwriter agrees that if it furnished an electronic copy of the Preliminary Prospectus used in connection with the Notes to any person, such Underwriter will furnish a printed copy of the Preliminary Prospectus to all persons to whom it previously sent an electronic copy and to whom it will send a written confirmation of sale.

If you are in agreement with this Underwriting Agreement, please sign a counterpart hereof and return it to the Seller and COAF, whereupon this Underwriting Agreement and your acceptance shall become a binding agreement among the Seller, COAF and the Underwriters.
