Dear Sirs:

Capital One Financial Corporation, a Delaware corporation (the “Company”), proposes to issue and sell 56,000,000 shares (the “Firm Shares”) of its common stock, par value $0.01 per share (the “Common Stock”) to you (the “Underwriter”). In addition, the Company proposes to grant to the Underwriter the option to purchase from the Company up to an additional 8,400,000 shares of Common Stock (the “Option Shares”). The Firm Shares and the Option Shares are hereinafter collectively sometimes referred to as the “Shares.” The Shares are described in the Prospectus which is referred to below.

1. Registration Statement and Prospectus. The Company has prepared and filed with the Securities and Exchange Commission (the “Commission”) a registration statement on Form S-3 (File No. 333-159085) under the Securities Act of 1933, as amended (the “Securities Act”) in respect of its debt securities, its junior subordinated debt securities, shares of its preferred stock, $0.01 par value, depositary shares, shares of its Common Stock, its purchase contracts, units, trust preferred securities that may be issued by a related trust, and warrants (as amended through the date of this Agreement, being herein referred to as the “Registration Statement”). Such Registration Statement has become effective. The Registration Statement contains a base prospectus in the form in which it has most recently been filed with the Commission on or prior to the date of this Agreement (the “Base Prospectus”), to be used in connection with the public offering and sale of the Shares. Any preliminary prospectus supplement to the Base Prospectus that describes the Shares and the offering thereof and is used prior to filing of the Prospectus is called, together with the Base Prospectus, a “preliminary prospectus.” The term “Prospectus” shall mean the final prospectus supplement relating to the Shares, together with the Base Prospectus, that is first filed pursuant to Rule 424(b) under the Securities Act after the date and time that this Agreement is executed and delivered by the parties hereto but shall not include any free writing prospectus (as such term is used in Rule 405 under the Securities Act). Any Prospectus shall be deemed to refer to and

include the documents incorporated by reference therein pursuant to Item 12 of Form S-3 under the Securities Act; any reference to any amendment or supplement to any preliminary prospectus or the Prospectus shall be deemed to refer to and include any documents filed after the date of such preliminary prospectus or Prospectus, as the case may be, under the Securities Exchange Act of 1934, as amended, and the rules and regulations promulgated thereunder (collectively, the “Exchange Act”), and incorporated by reference in such preliminary prospectus or Prospectus, as the case may be. The Company also has prepared and filed (or will file) with the Commission the Issuer Free Writing Prospectuses (as defined below) set forth on Schedule I hereto. All references in this Agreement to the Registration Statement, a preliminary prospectus, the Prospectus, or any amendments or supplements to any of the foregoing, shall include any copy thereof filed with the Commission pursuant to its Electronic Data Gathering, Analysis and Retrieval System (“XXXXX”).

2. Agreements to Sell and Purchase. On the basis of the representations and warranties contained in this Agreement, and subject to its terms and conditions, the Company agrees to issue and sell, and the Underwriter agrees to purchase from the Company the Firm Shares at a purchase price of $26.95 per Share (the “Purchase Price”).

In addition, the Company agrees to issue and sell the Option Shares to the Underwriter as provided in this Agreement, and the Underwriter, on the basis of the representations and warranties contained in this Agreement, and subject to its terms and conditions, shall have the option to purchase from the Company the Option Shares at the Purchase Price.

The Underwriter may exercise the option to purchase the Option Shares at any time in whole, or from time to time in part, on or before the thirtieth day following the date of this Agreement, by written notice from the Underwriter to the Company. Such notice shall set forth the aggregate number of Option Shares as to which the option is being exercised and the date and time when the Option Shares are to be delivered and paid for which may be the same date and time as the Closing Date (as hereinafter defined) but shall not be earlier than the Closing Date nor later than the tenth full business day after the date of such notice. Any such notice shall be given at least two business days prior to the date and time of delivery specified therein.

3. Terms of Public Offering. The Company is advised by you that you propose (i) to make a public offering of their respective portions of the Shares as soon after the execution hereof as practicable and (ii) initially to offer the Shares upon the terms set forth in the Prospectus.

4. Delivery and Payment. The Company will deliver, or cause to be delivered, the Shares to the Underwriter for its account against payment by or on behalf of the Underwriter of the Purchase Price by wire transfer of Federal (same-day) funds to the account specified by the Company to the Underwriter at least twenty-four hours in advance, by causing Computershare Investor Services, LLC, as registrar, to register the Shares in the name of Cede & Co., or such other nominee as DTC may designate, and shall cause DTC to credit the Shares to the account of the Underwriter at DTC. The time

Any such free writing prospectus consented to by the Underwriter is hereinafter referred to as a “Permitted Free Writing Prospectus.” The Company agrees that (i) it has treated and will treat, as the case may be, each Permitted Free Writing Prospectus as an Issuer Free Writing Prospectus, and (ii) has complied or will comply, as the case may be, with the requirements of Rules 164 and 433 of the Securities Act applicable to any Permitted Free Writing Prospectus, including in respect of timely filing with the Commission, legending and record keeping.

(bb) The charges, accruals and reserves on the books of the Company in respect of any income and corporation tax liability for any years not finally determined are adequate to meet any assessments or re-assessments for additional income tax for any years not finally determined, except to the extent of any inadequacy that would not have a material adverse affect on the Company and its subsidiaries, taken as a whole.

7. Representations and Warranties of the Underwriter. The Underwriter hereby represents and agrees that it has not and will not make any offer relating to the Shares that would constitute a “free writing prospectus” as defined in Rule 405 under the Securities Act without the prior consent of the Company or as permitted in Section 5(e) above and that Schedule I hereto is a complete list of any free writing prospectus for which the Underwriter has received such consent.

8. Indemnification. (a) The Company agrees to indemnify and hold harmless the Underwriter and each person, if any, who controls the Underwriter within the meaning of Section 15 of the Securities Act or Section 20 of the Exchange Act, from and against any and all losses, claims, damages, liabilities and judgments arising out of or based upon any untrue statement or alleged untrue statement of a material fact contained in the Registration Statement, the Prospectus, the Disclosure Package or any Issuer Free Writing Prospectus (each as amended or supplemented if the Company shall have furnished any amendments or supplements thereto) or any preliminary prospectus, or arising out of or based upon any omission or alleged omission to state therein a material fact required to be stated therein or necessary to make the statements therein not misleading, except insofar as such losses, claims, damages, liabilities or judgments are caused by any such untrue statement or omission or alleged untrue statement or omission based upon information relating to the Underwriter furnished in writing to the Company by or on behalf of the Underwriter through you expressly for use therein, it being understood and agreed that the only such information furnished by or on behalf of the Underwriter consists of the information described as such in this Section 8.

(b) In case any action shall be brought against the Underwriter or any person controlling the Underwriter, based upon any preliminary prospectus, the Registration Statement, the Prospectus or the Disclosure Package or any amendment or supplement thereto and with respect to which indemnity may be sought against the Company, the Underwriter shall promptly notify the Company in writing and the Company shall assume the defense thereof, including the employment of counsel reasonably satisfactory to such indemnified party and payment of all fees and expenses. The Underwriter or any such controlling person shall have the right to employ separate counsel in any such action and participate in the defense thereof, but the fees and expenses of such counsel shall be at the expense of the Underwriter or such controlling person unless (i) the employment of such counsel shall have been specifically authorized in writing by the Company, (ii) the Company shall have failed to assume the defense and employ counsel or (iii) the named parties to any such action (including any impleaded parties) include both the Underwriter or such controlling person and the Company and the Underwriter or such controlling person shall have been advised by such counsel that there may be one or more legal defenses available to it which are different from or additional to those available to the

Company (in which case the Company shall not have the right to assume the defense of such action on behalf of the Underwriter or such controlling person, it being understood, however, that the Company shall not, in connection with any one such action or separate but substantially similar or related actions in the same jurisdiction arising out of the same general allegations or circumstances, be liable for the reasonable fees and expenses of more than one separate firm of attorneys (in addition to any local counsel) for the Underwriter and controlling persons, which firm shall be designated in writing by the Underwriter, and that all such reasonable fees and expenses shall be reimbursed as they are incurred). The Company shall not be liable for any settlement of any such action effected without its written consent but if settled with the written consent of the Company, the Company agrees to indemnify and hold harmless the Underwriter and any such controlling person from and against any loss or liability by reason of such settlement. No indemnifying party shall, without the prior written consent of the indemnified party, effect any settlement of any pending or threatened proceeding 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 (i) an unconditional release of such indemnified party from all liability on claims that are the subject matter of such proceeding and (ii) does not include any statement as to, or an admission of, fault, culpability or failure to act by or on behalf of any indemnified party.

(c) The Underwriter agrees to indemnify and hold harmless the Company, each of its directors and each of its officers who signs the Registration Statement and each person controlling the Company within the meaning of Section 15 of the Securities Act or Section 20 of the Exchange Act, to the same extent as the foregoing indemnity from the Company to the Underwriter but only to the extent of losses, claims, damages, liabilities and judgments arising out of or based upon information relating to the Underwriter furnished in writing by or on behalf of the Underwriter expressly for use in the Registration Statement, the Base Prospectus, the Disclosure Package or the Prospectus. You confirm that the Underwriter’s name on the cover page of the preliminary prospectus supplement and the Prospectus and the Underwriter’s name in the first paragraph and the statements set forth in the eleventh, twelfth and thirteenth paragraphs under the heading “Underwriting” in the preliminary prospectus supplement and the Prospectus were furnished in writing to the Company by or on behalf of the Underwriter expressly for use therein. In case any action shall be brought against the Company, any of its directors, any such officer or any person controlling the Company based on the Registration Statement, the Base Prospectus, any preliminary prospectus or the Prospectus and in respect of which indemnity may be sought against the Underwriter, the Underwriter shall have the rights and duties given to the Company (except that if the Company shall have assumed the defense thereof, the Underwriter shall not be required to do so, but may employ separate counsel therein and participate in the defense thereof, but the fees and expenses of such counsel shall be at the expense of the Underwriter), and the Company, its directors, any such officers and any person controlling the Company shall have the rights and duties given to the Underwriter, by Section 8(b) hereof.

(d) If the indemnification provided for in paragraphs (a), (b) and (c) of this Section 8 is unavailable to an indemnified party in respect of any losses, claims, damages, liabilities or judgments referred to therein, then each indemnifying party, in lieu

of indemnifying such indemnified party, shall contribute to the amount paid or payable by such indemnified party as a result of such losses, claims, damages, liabilities and judgments (i) in such proportion as is appropriate to reflect the relative benefits received by the Company on the one hand and the Underwriter on the other hand from the offering of the Shares 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 the Underwriter in connection with the statements or omissions which resulted in such losses, claims, damages, liabilities or judgments, as well as any other relevant equitable considerations. The relative benefits received by the Company and the Underwriter shall be deemed to be in the same proportion as the total net proceeds from the offering (before deducting expenses) received by the Company, and the total underwriting discounts and commissions received by the Underwriter, bear to the total price to the public of the Shares, in each case as set forth in the table on the cover page of the Prospectus. The relative fault of the Company and the Underwriter shall be determined by reference to, among other things, whether the untrue or alleged untrue statement of a material fact or the omission to state a material fact relates to information supplied by the Company or the Underwriter and the parties’ relative intent, knowledge, access to information and opportunity to correct or prevent such statement or omission.

The Company and the Underwriter agree that it would not be just and equitable if contribution pursuant to this Section 8(d) were determined by pro rata allocation or by any other method of allocation which does not take account of the equitable considerations referred to in the immediately preceding paragraph. The amount paid or payable by an indemnified party as a result of the losses, claims, damages, liabilities or judgments referred to in the immediately preceding paragraph shall be deemed to include, subject to the limitations set forth above, any legal or other expenses reasonably incurred by such indemnified party in connection with investigating or defending any such action or claim. Notwithstanding the provisions of this Section 8, the Underwriter shall not be required to contribute any amount in excess of the amount by which the total price at which the Shares underwritten by it and distributed to the public were offered to the public exceeds the amount of any damages which the 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 Securities Act) shall be entitled to contribution from any person who was not guilty of such fraudulent misrepresentation.

9. Conditions of Underwriter’s Obligations. The obligation of the Underwriter to purchase the Shares under this Agreement are subject to the satisfaction of each of the following conditions:
