Ladies and Gentlemen:

Section 1. Introductory.

Capital One Auto Receivables, LLC, a Delaware limited liability company (the “Seller”) and Capital One Auto Finance, Inc., a Texas corporation, (“COAF”), confirm their agreement with the Representatives and the other underwriters named in the applicable Terms Agreement (collectively, the “Underwriters”) as follows:

The Seller proposes to sell to the Underwriters the notes of the classes designated in the applicable Terms Agreement (as hereinafter defined) (the “Notes”). The Notes are to be issued by Capital One Auto Finance Trust 2006-B, a Delaware statutory trust (the “Issuer”) under the Indenture (the “Indenture”), dated as of the Closing Date, between the Issuer and JPMorgan Chase Bank, N.A., as indenture trustee (the “Indenture Trustee”).

The Notes will be collateralized by the Trust Estate (as defined below). The assets of the Issuer (the “Trust Estate”) consist of all money, accounts, chattel paper, general intangibles, goods, instruments, investment property and other property of the Issuer, including without limitation (i) the Receivables acquired by the Issuer under the Sale and Servicing Agreement, dated as of the Closing Date, by and among the Seller, the Issuer, COAF and the Indenture Trustee (the “Sale and Servicing Agreement”), (ii) the Receivable Files, (iii) the security interests in the Financed Vehicles and all Certificates of Title in the Financed Vehicles, (iv) any proceeds from claims on any Insurance Policy and refunds in connection with extended service agreements relating to Receivables which became Defaulted Receivables after the applicable Cut-Off Date, (v) any other property securing the Receivables, (vi) the rights of the Issuer to the funds on deposit from time to time in the Trust Accounts and any other account or accounts

established pursuant to the Indenture or Sale and Servicing Agreement and all cash, investment property and other property from time to time credited thereto and all proceeds thereof (including investment earnings, net of losses and investment expenses, on amounts on deposit therein), (vii) the rights of the Seller, as buyer, under the Purchase Agreement, (viii) rights under the Sale and Servicing Agreement, the Limited Guaranty and the Interest Rate Swap Agreement and (ix) all proceeds of the foregoing.

The Receivables and related property will be conveyed to the Seller by COAF pursuant to the Purchase Agreement, dated as of the Closing Date, between the Seller and COAF (the “Purchase Agreement”) and will be conveyed to the Issuer by the Seller pursuant to the Sale and Servicing Agreement.

On the Closing Date, the Issuer will enter into an interest rate swap agreement with the Initial Swap Counterparty to hedge the floating interest rate on the Class A-4 Notes (the “Swap Agreement”).

On the Closing Date the Note Insurer will issue a note guaranty insurance policy (the “Note Insurance Policy”) guaranteeing certain payments due in respect of the Notes.

The terms of the Notes are set forth in the Registration Statement (as defined below) and the related Prospectus (as defined below), as supplemented by a Prospectus Supplement (as defined below).

Capitalized terms used herein but not defined herein or in the Terms Agreement (as defined below) shall have the meanings given such terms in Appendix A to the Sale and Servicing Agreement.

The Seller has prepared and filed with the Securities and Exchange Commission (the “Commission”) in accordance with the provisions of the Securities Act of 1933, as amended, and the rules and regulations of the Commission thereunder (collectively, the “Act”), a shelf registration statement on Form S-3 (having the registration number 333-128722), including a form of prospectus, relating to the Notes. The registration statement as amended has been declared effective by the Commission not more than three years prior to the date hereof. If any post-effective amendment has been filed with respect thereto, prior to the execution and delivery of the applicable Terms Agreement, the most recent such amendment has been declared effective by the Commission. Such registration statement, as amended at the time of effectiveness, including all material incorporated by reference therein and including all information (if any) deemed to be part of the registration statement at the time of effectiveness pursuant to Rule 430B under the Act, is referred to in this Agreement as the “Registration Statement.” The Company proposes to file with the Commission pursuant to Rule 424(b) under the Act (“Rule 424(b)”) a supplement (the “Prospectus Supplement”) to the prospectus included in the Registration Statement (such prospectus, in the form it appears in the Registration Statement or in the form most recently revised and filed with the Commission pursuant to Rule 424(b) is hereinafter referred to as the “Basic Prospectus”) relating to the Notes and the method of distribution thereof. The Basic Prospectus and the Prospectus Supplement, together with any amendment thereof or supplement thereto, is hereinafter referred to as the “Prospectus.”

Prior to the date and time the first Contract of Sale (as defined below) for the Notes designated in the Terms Agreement (the “Time of Sale”), the Seller had prepared a preliminary prospectus, dated July 25, 2006 (subject to completion). As used herein, “Preliminary Prospectus” means, with respect to any date or time referred to herein, the most recent preliminary Prospectus (as amended or supplemented, if applicable), which has been prepared and delivered by the Seller to the Underwriters in accordance with the provisions hereof.

Pursuant to this Agreement and the Terms Agreement, among COAF, the Seller and the Representatives, a form of which is attached hereto as Exhibit A (the “Terms Agreement”), which incorporates by reference this Underwriting Agreement (the “Agreement,” which shall include the applicable Terms Agreement if the context so requires), and subject to the terms hereof and thereof, the Seller agrees to sell to the Underwriters named in such Terms Agreement, for whom you are acting as the Representatives the Notes identified in such Terms Agreement.

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.

Each Underwriter further agrees that if it delivers to an investor the Prospectus in .pdf format, upon such Underwriter’s receipt of a request from the investor within the period for which delivery of the Prospectus is required, such Underwriter will promptly deliver or cause to be delivered to the investor, without charge, a paper copy of the Prospectus.

(h) In relation to each Member State of the European Economic Area which has implemented the Prospectus Directive (each, a “Relevant Member State”), each Underwriter

represents and agrees with the Seller that with effect from and including the date on which the Prospectus Directive is implemented in that Relevant Member State (the “Relevant Implementation Date”) it has not made and will not make an offer of Notes to the public in that Relevant Member State prior to the publication of a prospectus in relation to the Notes which has been approved by the competent authority in that Relevant Member State or, where appropriate, approved in another Relevant Member State and notified to the competent authority in that Relevant Member State, all in accordance with the Prospectus Directive, except that it may, with effect from and including the Relevant Implementation Date, make an offer of Notes to the public in that Relevant Member State at any time:

(i) to legal entities which are authorised or regulated to operate in the financial markets or, if not so authorised or regulated, whose corporate purpose is solely to invest in securities;

(ii) to any legal entity which has two or more of (1) an average of at least 250 employees during the last financial year; (2) a total balance sheet of more than €43,000,000 and (3) an annual net turnover of more than €50,000,000, as shown in its last annual or consolidated accounts; or

(i) If the Seller, COAF or an Underwriter determines or becomes aware that any “written communication” (as defined in Rule 405 under the Act) (including without limitation the Preliminary Prospectus) or oral statement (when considered in conjunction with all information conveyed at the time of the “contract of sale” within the meaning of Rule 159 under the Act and all Commission guidance relating to such rule (the “Contract of Sale”)) made or prepared by the Seller or such Underwriter contains an untrue statement of material fact or omits to state a material fact necessary to make the statements, in light of the circumstances under which they were made, not misleading at the time that a Contract of Sale was entered into, either the Seller or such Underwriter may prepare corrective information, with notice to the other party and such Underwriter shall deliver such information in a manner reasonably acceptable to both parties, to any person with whom a Contract of Sale was entered into based on such written communication or oral statement, and such information shall provide any such person with the following:

(i) adequate disclosure of the contractual arrangement;

(ii) adequate disclosure of the person’s rights under the existing Contract of Sale at the time termination is sought;

(iii) adequate disclosure of the new information that is necessary to correct the misstatements or omissions in the information given at the time of the original Contract of Sale; and

(iv) a meaningful ability to elect to terminate or not terminate the prior Contract of Sale and to elect to enter into or not enter into a new Contract of Sale.

Any costs or losses incurred in connection with any such termination or reformation shall be subject to Section 8.

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 Preliminary Prospectus, or 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, (ii) when any supplement or amendment to the Preliminary Prospectus or Prospectus has been filed and (iii) of any order or communication suspending or preventing, or threatening to suspend or prevent, the offer and sale of the Notes, or any prevention or suspension of the use of the Preliminary Prospectus or the Prospectus 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 Preliminary Prospectus or Prospectus relating to the Notes is required to be delivered under the Act (or required to be delivered but for Rule 172 under the Act), any event occurs as a result of which the Preliminary

Prospectus or 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) of this Agreement) 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 of this Agreement.

(c) The Seller will make (or will cause the Issuer to make) generally available to the Noteholders (the sole Noteholders being the applicable clearing agency in the case of Book-Entry Notes (as defined in Appendix A to the Sale and Servicing Agreement)), 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.

(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 Preliminary Prospectus or Prospectus or any portion thereof is required under Rule 424(b) of the Commission, the Seller will file the Preliminary Prospectus or 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.

(i) At the time of the execution and delivery of each subsequent transfer, the related 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 related Subsequent Receivables will meet the eligibility criteria described in the Prospectus.

Section 6. Conditions to the Obligations of the Underwriters.

The obligations of the Underwriters to purchase and pay for the Notes will be subject to the accuracy of the representations and warranties made by 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:

(a) The Representatives shall have received, with respect to each of the Seller and COAF, a certificate, dated the Closing Date, of an authorized officer of each of the Seller and COAF, as applicable, in which such officer, to the best of his or her knowledge after reasonable investigation, shall state that: (i) the representations and warranties of the Seller or COAF, as applicable, in this Underwriting Agreement are true and correct in all material respects on and as of the Closing Date, (ii) the Seller or COAF, as applicable, has complied in all material respects with all agreements and satisfied all conditions on its part to be performed or satisfied hereunder at or before the Closing Date, (iii) the Registration Statement has been declared effective, no stop order suspending the effectiveness of the Registration Statement has been issued and no proceedings for that purpose have been instituted or are threatened by the Commission, and (iv) since the Time of Sale, there has been no material adverse change in the condition (financial or otherwise) of the Seller’s or COAF’s, as applicable, automobile finance business, except as set forth in or contemplated in the Preliminary Prospectus (references to the Preliminary Prospectus in this clause include any amendments or supplements thereto).

(b) The Representatives shall have received an opinion of Mayer, Brown, Rowe & Maw LLP, special counsel to COAF and the Seller, dated the Closing Date, in form and substance satisfactory to the Representatives and their counsel, with respect to: certain corporate matters, perfection matters, matters related to the creation of a security interest, securities law matters, 1940 Act matters, tax matters and enforceability matters (including with respect to the Limited Guaranty).

Such counsel shall also state that they have participated in conferences with representatives of the Seller and COAF and their accountants, and representatives of the Underwriters and their counsel concerning the Registration Statement, the Preliminary Prospectus and the Prospectus and have considered the matters required to be stated therein and the matters stated therein, although they are not independently verifying the factual matters of such statements. Based upon and subject to the foregoing, nothing has come to such counsel’s attention to cause such counsel to believe that the Registration Statement (excluding any exhibits

filed therewith), at the earlier of the date the Prospectus was first used or the date on which the Time of Sale occurred, contained an untrue statement of a material fact or omitted to state a material fact required to be stated therein or necessary to make the statements therein not misleading, or that the Preliminary Prospectus, as of the Time of Sale, considered as a whole and together with the statements in the Prospectus with respect to items appearing in the Preliminary Prospectus as blanks, included an untrue statement of a material fact or omitted to state a material fact necessary in order to make the statements therein, in light of the circumstances under which they were made, not misleading, or that the Prospectus, as of its date or as of the date of such opinion, included or includes an untrue statement of a material fact or omitted or omits to state 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, however, that we do not assume any responsibility for the accuracy, completeness or fairness of the statements contained in the Registration Statement, the Preliminary Prospectus or the Prospectus, and we do not express any belief with respect to (i) the financial statements or other financial, statistical or accounting data contained in or omitted from the Registration Statement, the Preliminary Prospectus or the Prospectus or (ii) the following information contained in the Preliminary Prospectus or the Prospectus: the Underwriter Information (as defined in Section 8(b)), the Note Insurer Information (as defined in Section 2(a)(iv)) and the Swap Counterparty Information (as defined in Section 2(a)(iv) or (v)).

(d) The Representatives shall have received from Dechert LLP, a favorable opinion dated the Closing Date, with respect to such matters as the Representatives may reasonably require; and the Seller and COAF shall have furnished to such counsel such documents as they reasonably request for the purpose of enabling them to pass on all such matters.

file a voluntary bankruptcy petition, (ii) certain corporate matters with respect to the Seller, (iii) certain matters with respect to the security interest of the Issuer and the Indenture Trustee, respectively, in the Receivables and related property.

(g) At the Closing Date, Ernst & Young, LLP shall have furnished to the Representatives a letter or letters, dated as of the Closing Date, in form and substance satisfactory to the Representatives and their counsel, confirming that they are certified independent public accountants and stating in effect that they have performed certain specified procedures as a result of which they determined that certain information of an accounting, financial or statistical nature (which is limited to accounting, financial or statistical information derived from the general accounting records of the Issuer, COAF and the Seller) set forth in the Prospectus Supplement and the related preliminary Prospectus Supplement, agrees with the accounting records of the Issuer, COAF and the Seller, excluding any questions of legal interpretation.

(h) The Representatives shall have received evidence satisfactory to the Representatives and their counsel that, on or before the Closing Date, UCC-1 financing statements have been filed (or have been sent for filing on the Closing Date) with the appropriate UCC filing offices in the State of Delaware and the State of Texas, reflecting the transfer of Receivables and other related property from COAF to the Seller, the transfer of Receivables and other related property from the Seller to the Issuer and the pledge of the Receivables and other related property by the Issuer in favor of the Indenture Trustee.

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.

(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 of this Agreement 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.

(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 Preliminary Prospectus (it being understood that such indemnification with respect to the Preliminary Prospectus does not include the omission of pricing and price-dependent information, which information shall of necessity appear only in the final Prospectus), the Prospectus or any amendment or supplement thereto, any related preliminary prospectus, or the Designated Static Pool Information 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 neither the Seller nor COAF shall 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. 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 (i) any untrue statement or alleged untrue statement of any material fact contained in the Registration Statement, Preliminary Prospectus, the Prospectus, or any amendment or supplement thereto, 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 the Underwriter Information (as defined below), and (ii) the failure upon the part of any Underwriter to deliver the Preliminary Prospectus prior to the Time of Sale to any investor with whom such Underwriter entered into a Contract of Sale at such Time of Sale 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. As used herein, the term “Underwriter Information” means 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 Preliminary Prospectus or Prospectus. This indemnity agreement will be in addition to any liability that each Underwriter may otherwise have.

(c) 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, (i) any untrue statement or alleged untrue statement of any material fact contained in any Underwriter Free Writing Prospectus (as defined in Section 17(a)), 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 (ii) any statement contained in any Underwriter Free Writing Prospectus that conflicts with the information then contained in the Registration Statement or any prospectus or prospectus supplement that is a part thereof, and will reimburse any legal or other expenses reasonably incurred by the Seller or COAF in connection with investigating or defending any such loss, claim, damage, liability or action; provided, however, that with respect to clauses (i) and (ii) above, no Underwriter will be liable to the extent that any such loss, claim, damage or liability arises out of or is based upon any statement in or omission from any Underwriter Free Writing Prospectus in reliance upon and in

conformity with (A) any written information furnished to the related Underwriter by the Seller or COAF expressly for use therein, (B) information accurately extracted from the Preliminary Prospectus or Prospectus, which information was not corrected by information subsequently provided by the Seller or COAF to the related Underwriter prior to the time of use of such Underwriter Free Writing Prospectus or (C) Issuer Information (as defined in Section 17(a)) (except for information regarding the status of the subscriptions for the Notes). This indemnity agreement will be in addition to any liability that each Underwriter may otherwise have.

(d) 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), (b) or (c) 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), (b) or (c) 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 8 for any legal or other expenses (including fees and expenses of counsel) subsequently incurred by such indemnified party in connection with the 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 (i) includes an unconditional release of such indemnified party from all liability on any claims that are the subject matter of such action and (ii) does not include a statement as to an admission of fault, culpability or a failure to act on behalf of any indemnified party. 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.

(e) If the indemnification provided for in this Section 8 is unavailable or insufficient to hold harmless an indemnified party under subsection (a), (b) or (c) 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 (e) 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 (d) 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 (e). Notwithstanding the provisions of this clause (e), 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(e) shall be several in proportion to their respective underwriting obligations and not joint.

(f) The obligations of the indemnifying party under this Section 8 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 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.

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 of this Agreement and Section 8 of this Agreement 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 in the Terms Agreement 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 in the Terms Agreement, 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. Offering Communications.

(a) Other than the Preliminary Prospectus, the Prospectus and any Free Writing Prospectus identified in the Terms Agreement, each Underwriter severally represents, warrants and agrees with COAF and the Seller that it has not made, used, prepared, authorized,

approved or referred to and will not prepare, make, use, authorize, approve or refer to any “written communication” (as defined in Rule 405 under the Act) that constitutes an offer to sell or solicitation of an offer to buy the Notes, including, but not limited to any “ABS informational and computational materials” as defined in Item 1101(a) of Regulation AB under the Act unless such Underwriter has obtained the prior written approval of COAF, the Issuer and the Seller; provided, however, each Underwriter may prepare and convey to one or more of its potential investors without the consent of COAF, the Seller or any of their respective affiliates one or more “written communications” (as defined in Rule 405 under the Act) in the form of (i) an Intex CDI file that does not contain any Issuer Information (as defined below) other than Issuer Information included in the Preliminary Prospectus previously filed with the Commission or (ii) other written communication containing no more than the following: information contemplated by Rule 134 under the Act and included or to be included in the Preliminary Prospectus or the Prospectus, as well as a column or other entry showing the status of the subscriptions for the Notes and/or expected pricing parameters of the Notes (each such written communication, an “Underwriter Free Writing Prospectus”).

(i) each Underwriter Free Writing Prospectus prepared by it will not, as of the date such Underwriter Free Writing Prospectus was conveyed or delivered to any prospective purchaser of Notes, include any untrue statement of a material fact or omit any material fact necessary to make the statements contained therein, in light of the circumstances under which they were made, not misleading; provided, however, that no Underwriter makes such representation, warranty or agreement to the extent such untrue statements or omissions were made in reliance upon and in conformity with information contained in the Preliminary Prospectus or the Prospectus or any written information furnished to the related Underwriter by COAF or the Seller specifically for use therein which information was not corrected by information subsequently provided by COAF or the Seller to the related Underwriter prior to the time of use of such Underwriter Free Writing Prospectus;

(ii) each Underwriter Free Writing Prospectus prepared by it shall contain a legend substantially in the form of and in compliance with Rule 433(c)(2)(i) of the Act, and shall otherwise conform to any requirements for “free writing prospectuses” under the Act;

(iv) none of the information in any Underwriter Free Writing Prospectus will conflict with the information then contained in the Registration Statement or any prospectus or prospectus supplement that is a part thereof;

In addition, such Underwriter shall, for a period of at least three years after the date hereof, maintain written and/or electronic records of the following:

(i) any Underwriter Free Writing Prospectus used by such Underwriter to solicit offers to purchase Notes to the extent not filed with the Commission;

(ii) regarding each Underwriter Free Writing Prospectus delivered by such Underwriter to an investor, the date of such delivery and identity of such investor; and

(vi) such Underwriter shall file any Underwriter Free Writing Prospectus that has been distributed by such Underwriter in a manner reasonably designed to lead to its broad, unrestricted dissemination within the later of two business days after such Underwriter first provides this information to investors and the date upon which the Company is required to file the Prospectus Supplement with the Commission pursuant to Rule 424(b)(3) of the Act or otherwise as required under Rule 433 of the Act; provided, however, that such Underwriter shall not be required to file any Underwriter Free Writing Prospectus to the extent such Underwriter Free Writing Prospectus includes information in a Free Writing Prospectus, Preliminary Prospectus or Prospectus previously filed with the Commission or that does not contain substantive changes from or additions to a Free Writing Prospectus previously filed with the Commission.

Each of the Seller and COAF waives to the full extent permitted by applicable law any claims it may have against the Underwriters arising from an alleged breach of fiduciary duty in connection with the offering of the Notes.

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.
