Subject to the terms and conditions of this Agreement, the closing of the Merger (the “Closing”) will take place by electronic exchange of documents at 10:00 a.m., New York City time, on a date which shall be no later than three (3) business days after the satisfaction or waiver (subject to applicable law) of all of the conditions set forth in Article VII hereof (other than those conditions that by their nature can only be satisfied at the Closing, but subject to the satisfaction or waiver thereof), unless another date, time or place is agreed to in writing by Discover and Capital One.

2.1 Capital One to Make Consideration Available. At or prior to the Effective Time, Capital One shall deposit, or shall cause to be deposited, with a bank or trust company designated by Capital One and reasonably acceptable to Discover (the “Exchange Agent”), for exchange in accordance with this Article II for the benefit of the holders of Old Certificates (which for purposes of this Article II shall be deemed to include certificates or book-entry account statements representing shares of Discover Preferred Stock), certificates or, at Capital One’s option, evidence in book-entry form, representing shares of Capital One Common Stock or New Capital One Preferred Stock to be issued pursuant to Section 1.5 and Section 1.8, respectively (collectively, referred to herein as “New Certificates”), and cash in lieu of any fractional shares to be paid pursuant to Section 2.2(e) (such cash and New Certificates, together with any dividends or distributions with respect to shares of Capital One Common Stock or New Capital One Preferred Stock payable in accordance with Section 2.2(b), being hereinafter referred to as the “Exchange Fund”).

2.2 Exchange of Shares.

(a) As promptly as practicable after the Effective Time, but in no event later than five (5) days thereafter, Capital One shall cause the Exchange Agent to mail to each holder of record of one or more Old Certificates representing shares of Discover Common Stock or Discover Preferred Stock immediately prior to the Effective Time that have been converted at the Effective Time or the Second Effective Time, as applicable, into the right to receive Capital One Common Stock or New Capital One Preferred Stock, as applicable, pursuant to Article I, a letter of transmittal (which shall specify that delivery shall be effected, and risk of loss and title to the Old Certificates shall pass, only upon proper delivery of the Old Certificates to the Exchange Agent) and instructions for use in effecting the surrender of the Old Certificates in exchange for New Certificates representing the number of whole shares of Capital One Common Stock and

-7-

any cash in lieu of fractional shares or shares of New Capital One Preferred Stock, as applicable, which the shares of Discover Common Stock or Discover Preferred Stock represented by such Old Certificate or Old Certificates shall have been converted into the right to receive pursuant to this Agreement as well as any dividends or distributions to be paid pursuant to Section 2.2(b). Upon proper surrender of an Old Certificate or Old Certificates for exchange and cancellation to the Exchange Agent, together with such properly completed letter of transmittal, duly executed, the holder of such Old Certificate or Old Certificates shall be entitled to receive in exchange therefor, as applicable, (i) (A) a New Certificate representing that number of whole shares of Capital One Common Stock to which such holder of Discover Common Stock shall have become entitled pursuant to the provisions of Article I and (B) a check representing the amount of (x) any cash in lieu of fractional shares which such holder has the right to receive in respect of the Old Certificate or Old Certificates surrendered pursuant to the provisions of this Article II and (y) any dividends or distributions which the holder thereof has the right to receive pursuant to Section 2.2(b) or (ii) (A) a New Certificate representing that number of shares of New Capital One Preferred Stock to which such holder of Discover Preferred Stock shall have become entitled pursuant to the provisions of Article I, and (B) a check representing the amount of any dividends or distributions which the holder thereof has the right to receive pursuant to Section 2.2(b), and the Old Certificate or Old Certificates so surrendered shall forthwith be cancelled. No interest will be paid or accrued on any cash in lieu of fractional shares or dividends or distributions payable to holders of Old Certificates. Until surrendered as contemplated by this Section 2.2, each Old Certificate shall be deemed at any time after the Effective Time or the Second Effective Time, as applicable, to represent only the right to receive, upon surrender, the number of whole shares of Capital One Common Stock or shares of New Capital One Preferred Stock which the shares of Discover Common Stock or Discover Preferred Stock, as applicable, represented by such Old Certificate have been converted into the right to receive and any cash in lieu of fractional shares or in respect of dividends or distributions as contemplated by this Section 2.2.

(b) No dividends or other distributions declared with respect to Capital One Common Stock or New Capital One Preferred Stock shall be paid to the holder of any unsurrendered Old Certificate until the holder thereof shall surrender such Old Certificate in accordance with this Article II. After the surrender of an Old Certificate in accordance with this Article II, the record holder thereof shall be entitled to receive any such dividends or other distributions, without any interest thereon, which theretofore had become payable with respect to the whole shares of Capital One Common Stock or shares of New Capital One Preferred Stock that the shares of Discover Common Stock or Discover Preferred Stock, as applicable, represented by such Old Certificate have been converted into the right to receive.

(c) If any New Certificate representing shares of Capital One Common Stock or New Capital One Preferred Stock is to be issued in a name other than that in which the Old Certificate or Old Certificates surrendered in exchange therefor is or are registered, it shall be a condition of the issuance thereof that the Old Certificate or Old Certificates so surrendered shall be properly endorsed (or accompanied by an appropriate instrument of transfer) and otherwise in proper form for transfer, and that the person requesting such exchange shall pay to the Exchange Agent in advance any transfer or other similar Taxes required by reason of the issuance of a New Certificate representing shares of Capital One Common Stock or New Capital One Preferred Stock in any name other than that of the registered holder of the Old Certificate or Old Certificates surrendered, or required for any other reason, or shall establish to the satisfaction of the Exchange Agent that such Tax has been paid or is not payable.

-8-

(d) After the Effective Time or the Second Effective Time, as applicable, there shall be no transfers on the stock transfer books of Discover of the shares of Discover Common Stock or Discover Preferred Stock that were issued and outstanding immediately prior thereto. If, after the Effective Time or Second Effective Time, as applicable, Old Certificates representing such shares are presented for transfer to the Exchange Agent, they shall be cancelled and exchanged for New Certificates representing shares of Capital One Common Stock or New Capital One Preferred Stock, as applicable, as provided in this Article II.

(e) Notwithstanding anything to the contrary contained herein, no New Certificates or scrip representing fractional shares of Capital One Common Stock shall be issued upon the surrender for exchange of Old Certificates, no dividend or distribution with respect to Capital One Common Stock shall be payable on or with respect to any fractional share, and such fractional share interests shall not entitle the owner thereof to vote or to any other rights of a stockholder of Capital One. In lieu of the issuance of any such fractional share, Capital One shall pay to each former holder of Discover Common Stock who otherwise would be entitled to receive such fractional share an amount in cash (rounded to the nearest cent) determined by multiplying (i) the average of the closing sale prices of Capital One Common Stock on the New York Stock Exchange (the “NYSE”) as reported by The Wall Street Journal for the consecutive period of five (5) full trading days ending on the day preceding the Closing Date by (ii) the fraction of a share (after taking into account all shares of Discover Common Stock held by such holder immediately prior to the Effective Time and rounded to the nearest one-thousandth when expressed in decimal form) of Capital One Common Stock which such holder would otherwise be entitled to receive pursuant to Section 1.5. The parties acknowledge that payment of such cash consideration in lieu of issuing fractional shares is not separately bargained-for consideration, but merely represents a mechanical rounding off for purposes of avoiding the expense and inconvenience that would otherwise be caused by the issuance of fractional shares.

(f) Any portion of the Exchange Fund that remains unclaimed by the stockholders of Discover for twelve (12) months after the Effective Time shall be paid to the Surviving Entity. Any former holders of Discover Common Stock or Discover Preferred Stock who have not theretofore complied with this Article II shall thereafter look only to the Surviving Entity for payment of the shares of Capital One Common Stock, cash in lieu of any fractional shares and any unpaid dividends and distributions on the Capital One Common Stock deliverable in respect of each former share of Discover Common Stock such holder holds as determined pursuant to this Agreement, or the shares of New Capital One Preferred Stock and any unpaid dividends and distributions on the New Capital One Preferred Stock deliverable in respect of each former share of Discover Preferred Stock such holder holds as determined pursuant to this Agreement, in each case, without any interest thereon. Notwithstanding the foregoing, none of Capital One, Discover, the Surviving Entity, the Exchange Agent or any other person shall be liable to any former holder of shares of Discover Common Stock or Discover Preferred Stock for any amount delivered in good faith to a public official pursuant to applicable abandoned property, escheat or similar laws.

-9-

(g) Capital One shall be entitled to deduct and withhold, or cause the Exchange Agent to deduct and withhold, from any cash in lieu of fractional shares of Capital One Common Stock, cash dividends or distributions payable pursuant to this Section 2.2 or any other amounts otherwise payable pursuant to this Agreement to any holder of Discover Common Stock, Discover Preferred Stock or Discover Equity Awards, such amounts as it is required to deduct and withhold with respect to the making of such payment under the Code or any provision of state, local or foreign Tax law. To the extent that amounts are so withheld by Capital One or the Exchange Agent, as the case may be, and paid over to the appropriate governmental authority, the withheld amounts shall be treated for all purposes of this Agreement as having been paid to the holder of Discover Common Stock, Discover Preferred Stock or Discover Equity Awards in respect of which the deduction and withholding was made by Capital One or the Exchange Agent, as the case may be.

(h) In the event any Old Certificate shall have been lost, stolen or destroyed, upon the making of an affidavit of that fact by the person claiming such Old Certificate to be lost, stolen or destroyed and, if required by Capital One or the Exchange Agent, the posting by such person of a bond in such amount as Capital One or the Exchange Agent may determine is reasonably necessary as indemnity against any claim that may be made against it with respect to such Old Certificate, the Exchange Agent will issue in exchange for such lost, stolen or destroyed Old Certificate the shares of Capital One Common Stock and any cash in lieu of fractional shares, or the shares of New Capital One Preferred Stock, as applicable, deliverable in respect thereof pursuant to this Agreement.

Each of Capital One and Merger Sub is duly licensed or qualified to do business and in good standing in each jurisdiction in which the nature of the business conducted by it or the character or location of the properties and assets owned, leased or operated by it makes such licensing, qualification or standing necessary, except where the failure to be so licensed or qualified or to be in good standing would not, either individually or in the aggregate, reasonably be expected to have a Material Adverse Effect on Capital One. True and complete copies of the Restated Certificate of Incorporation of Capital One (the “Capital One Charter”) and the Amended and Restated Bylaws of Capital One (the “Capital One Bylaws”) and the certificate of incorporation of Merger Sub (the “Merger Sub Charter”) and the bylaws of Merger Sub (the “Merger Sub Bylaws”), in each case as in effect as of the date of this Agreement, have previously been made available by Capital One to Discover.

(b) Each Subsidiary of Capital One (a “Capital One Subsidiary”) (i) is duly organized and validly existing under the laws of its jurisdiction of organization, (ii) is duly licensed or qualified to do business and, where such concept is recognized under applicable law, in good standing in all jurisdictions (whether federal, state, local or foreign) where its ownership, leasing or operation of property or the conduct of its business requires it to be so licensed or

Section 4.1(b) of the Capital One Disclosure Schedule sets forth a true and complete list of all Subsidiaries of Capital One that would constitute significant Subsidiaries.

Discover, after receiving the advice of its outside counsel and, with respect to financial matters, its financial advisors, determines in good faith that it would more likely than not result in a violation of its fiduciary duties under applicable law to make or continue to make the Capital One Board Recommendation or the Discover Board Recommendation, as applicable, such Board of Directors may, in the case of Capital One, prior to the receipt of the Requisite Capital One Vote, and in the case of Discover, prior to the receipt of the Requisite Discover Vote, submit this Agreement to its stockholders without recommendation (although the resolutions approving this Agreement as of the date hereof may not be rescinded or amended), in which event such Board of Directors may communicate the basis for its lack of a recommendation to its stockholders in the Joint Proxy Statement or an appropriate amendment or supplement thereto to the extent required by law; provided that such Board of Directors may not take any actions under this sentence unless it (A) gives the other party at least three (3) business days’ prior written notice of its intention to take such action and a reasonable description of the event or circumstances giving rise to its determination to take such action (including, in the event such action is taken in response to an Acquisition Proposal, the latest material terms and conditions of, and the identity of the third party making, any such Acquisition Proposal, or any amendment or modification thereof, or describe in reasonable detail such other event or circumstances) and (B) at the end of such notice period, takes into account any amendment or modification to this Agreement proposed by the other party and, after receiving the advice of its outside counsel and, with respect to financial matters, its financial advisors, determines in good faith that it would nevertheless more likely than not result in a violation of its fiduciary duties under applicable law to make or continue to make the Capital One Board Recommendation or Discover Board Recommendation, as the case may be. Any material amendment to any Acquisition Proposal will be deemed to be a new Acquisition Proposal for purposes of this Section 6.3 and will require a new notice period as referred to in this Section 6.3. Capital One or Discover shall adjourn or postpone the Capital One Meeting or the Discover Meeting, as the case may be, if, as of the time for which such meeting is originally scheduled there are insufficient shares of Capital One Common Stock or Discover Common Stock, as the case may be, represented (either in person or by proxy) to constitute a quorum necessary to conduct the business of such meeting, or if on the date of such meeting Discover or Capital One, as applicable, has not received proxies representing a sufficient number of shares necessary to obtain the Requisite Discover Vote or the Requisite Capital One Vote; provided that the date of the Capital One Meeting or the Discover Meeting, as applicable, is not postponed or adjourned more than twice and in each case for more than an aggregate of 15 days in connection with any one postponement or adjournment or more than an aggregate of 30 days from the original date of the applicable meeting in reliance on the preceding sentence (excluding any adjournments or postponements required by applicable law). Notwithstanding anything to the contrary herein, unless this Agreement has been terminated in accordance with its terms, (x) the Capital One Meeting shall be convened and the Capital One Share Issuance shall be submitted to the stockholders of Capital One at the Capital One Meeting and (y) the Discover Meeting shall be convened and this Agreement shall be submitted to the stockholders of Discover at the Discover Meeting, and nothing contained herein shall be deemed to relieve either Capital One or Discover of such obligation. As used in this Agreement, “Acquisition Proposal” shall mean, with respect to Capital One or Discover, as applicable, other than the transactions contemplated by this Agreement, any offer, inquiry or proposal relating to, or any third party indication of interest in, (i) any acquisition or purchase, direct or indirect, of twenty-five percent (25%) or more of the consolidated assets of a party and its Subsidiaries or

-63-

twenty-five percent (25%) or more of any class of equity or voting securities of a party or its Subsidiaries whose assets, individually or in the aggregate, constitute twenty-five percent (25%) or more of the consolidated assets of the party, (ii) any tender offer (including a self-tender offer) or exchange offer that, if consummated, would result in such third party beneficially owning twenty-five percent (25%) or more of any class of equity or voting securities of a party or its Subsidiaries whose assets, individually or in the aggregate, constitute twenty-five percent (25%) or more of the consolidated assets of the party, or (iii) a merger, consolidation, share exchange, business combination, reorganization, recapitalization, liquidation, dissolution or other similar transaction involving a party or its Subsidiaries whose assets, individually or in the aggregate, constitute twenty-five percent (25%) or more of the consolidated assets of the party.

6.4 Legal Conditions to Merger. Subject in all respects to Section 6.1 of this Agreement, each of Capital One and Discover shall, and shall cause its Subsidiaries to, use their reasonable best efforts (a) to take, or cause to be taken, all actions necessary, proper or advisable to comply promptly with all legal requirements that may be imposed on such party or its Subsidiaries with respect to the Mergers and the Bank Merger and, subject to the conditions set forth in Article VII hereof, to consummate the transactions contemplated by this Agreement, and (b) to obtain (and to cooperate with the other party to obtain) any material consent, authorization, order or approval of, or any exemption by, any Governmental Entity and any other third party that is required to be obtained by Discover or Capital One or any of their respective Subsidiaries in connection with the Mergers, the Bank Merger and the other transactions contemplated by this Agreement.

6.5 Stock Exchange Listing. Capital One shall cause the shares of Capital One Common Stock to be issued in the Merger to be approved for listing on the NYSE, subject to official notice of issuance, prior to the Effective Time.

6.6 Employee Matters.

(a) Capital One shall, and shall cause each of its Subsidiaries to, for the one-year period following the Effective Time, maintain for the each employee of Discover and any of its Subsidiaries as of the Effective Time who remains so employed immediately following the Effective Time (the “Continuing Employees”), for so long as they are employed by the Surviving Entity following the Effective Time (i) base salary or wages (as applicable) that is no less favorable than that provided to the Continuing Employee as of immediately prior to the Effective Time, (ii) target annual cash incentive compensation and target long-term incentive compensation opportunities that are no less favorable in the aggregate to the aggregate target annual cash incentive compensation and target long-term incentive compensation opportunities provided to the Continuing Employee as of immediately prior to the Effective Time, (iii) employee benefits (other than severance) that are substantially comparable in the aggregate to the employee benefits (other than severance) provided by Discover to the Continuing Employees as of immediately prior to the Effective Time, and (iv) severance benefits no less favorable than the severance benefits provided to the Continuing Employees under the plans listed in Section 6.6(a) of the Discover Disclosure Schedule.

-64-

(b) With respect to any Capital One Benefit Plans in which any Continuing Employees become eligible to participate on or after the Effective Time, Capital One shall, and shall cause each of its Subsidiaries to: (i) waive all pre-existing conditions, exclusions and waiting periods with respect to participation and coverage requirements applicable to such employees and their eligible dependents under any such Capital One Benefit Plans that provide health care benefits, except to the extent such pre-existing conditions, exclusions or waiting periods would apply under the analogous Discover Benefit Plan, (ii) use commercially reasonable efforts to provide each such employee and their eligible dependents with credit for any co-payments or coinsurance and deductibles paid prior to the Effective Time under a Capital One Benefit Plan that provides health care benefits, to the same extent that such credit was given under the analogous Discover Benefit Plan prior to the Effective Time, in satisfying any applicable deductible, co-payment, coinsurance or maximum out-of-pocket requirements under any such Capital One Benefit Plan, and (iii) use commercially reasonable efforts to recognize all service of such employees with Discover and its Subsidiaries for purposes of eligibility to participate, vesting and levels of benefits in any such Capital One Benefit Plan to the same extent that such service was taken into account under the analogous Discover Benefit Plan prior to the Effective Time; provided, that the foregoing service recognition shall not apply (A) to the extent it would result in a duplication of benefits for the same period of service, (B) for purposes of any pension plan or (C) for purposes of any benefit plan that is a frozen plan or provides grandfathered benefits.

(c) If requested by Capital One in writing delivered to Discover not less than twenty (20) business days before the Closing Date, the Board of Directors of Discover (or the appropriate committee thereof) shall adopt resolutions and take such corporate action as is necessary or appropriate to terminate the Discover 401(k) Plan (the “Discover 401(k) Plan”), effective as of the day prior to the Closing Date and contingent upon the occurrence of the Effective Time. If Capital One requests that the Discover 401(k) Plan be terminated, (i) Discover shall provide Capital One with evidence that such plan has been terminated (the form and substance of which shall be subject to reasonable review and comment by Capital One)not later than five (5) days immediately preceding the Closing Date and (ii) the Continuing Employees shall be eligible to participate, effective as of the Effective Time, in a 401(k) plan sponsored or maintained by Capital One or one of its Subsidiaries (the “Capital One 401(k) Plan”). Capital One and Discover shall take all actions as may be required, including amendments to the Discover 401(k) Plan and/or the Capital One 401(k) Plan, to permit the Continuing Employees to make rollover contributions to the Capital One 401(k) Plan of “eligible rollover distributions” (within the meaning of Section 401(a)(31) of the Code) in the form of cash, notes (in the case of loans) or a combination thereof.

(d) Effective as of the Effective Time, Capital One shall, or shall cause one of its Subsidiaries to, assume and honor the Discover Benefit Plans in accordance with their terms, it being understood that this sentence shall not be construed to limit the ability of Capital One or any of its Subsidiaries or Affiliates to amend or terminate any Discover Benefit Plan in accordance with its terms.

(e) Following the date hereof, Discover and Capital One shall, and shall cause their respective Affiliates to, cooperate and use good faith efforts in all matters reasonably necessary for employee, compensation and benefits integration, including exchanging information and data relating to employees, organizational structure, compensation and employee benefits, and distributing communications to the employees of Discover and its

-65-

Affiliates. Prior to the Closing, Capital One shall be provided the opportunity to review and comment on any broad-based or otherwise material employee notices or communication materials (including website postings) regarding the transactions contemplated by this Agreement from Discover or its Affiliates to the employees of Discover and its Affiliates, including broad-based or otherwise material notices or communication materials with respect to employment, compensation or benefits matters addressed in this Agreement or related, directly or indirectly, to the transactions contemplated by this Agreement or employment after the Closing prepared by Discover or its Affiliates prior to their distribution, and Discover and its Affiliates shall reflect any reasonable comments promptly received from Capital One.

(f) Nothing in this Agreement shall confer upon any employee, officer, director or consultant of Capital One or Discover or any of their Subsidiaries or Affiliates any right to continue in the employ or service of the Surviving Entity, Discover, Capital One or any Subsidiary or Affiliate thereof, or shall interfere with or restrict in any way the rights of the Surviving Entity, Discover, Capital One or any Subsidiary or Affiliate thereof to discharge or terminate the services of any employee, officer, director or consultant of the Surviving Entity, Discover, Capital One or any of their Subsidiaries or Affiliates at any time for any reason whatsoever, with or without cause. Nothing in this Agreement shall be deemed to (i) establish, amend, or modify any Discover Benefit Plan, Capital One Benefit Plan or any other benefit or employment plan, program, agreement or arrangement, or (ii) alter or limit the ability of the Surviving Entity, Discover, Capital One or any of their Subsidiaries or Affiliates to amend, modify or terminate any Discover Benefit Plan, Capital One Benefit Plan or any other benefit or employment plan, program, agreement or arrangement after the Effective Time. Without limiting the generality of Section 9.11, nothing in this Section 6.6, express or implied, is intended to or shall confer upon any person, including any current or former employee, officer, director or consultant of the Surviving Entity, Discover, Capital One or any of their Subsidiaries or Affiliates, any right, benefit or remedy of any nature whatsoever under or by reason of this Agreement.

6.7 Indemnification; Directors’ and Officers’ Insurance.

(a) From and after the Effective Time, the Surviving Entity shall indemnify and hold harmless and shall advance expenses as incurred, in each case to the extent (subject to applicable law) such persons are indemnified as of the date of this Agreement by Discover pursuant to the Discover Charter, the Discover Bylaws, the governing or organizational documents of any Subsidiary of Discover and any indemnification agreements in existence as of the date hereof and disclosed in Section 6.7(a) of the Discover Disclosure Schedule, each present and former director, officer or employee of Discover and its Subsidiaries (in each case, when acting in such capacity) (collectively, the “Discover Indemnified Parties”) against any costs or expenses (including reasonable attorneys’ fees), judgments, fines, losses, damages or liabilities incurred in connection with any threatened or actual claim, action, suit, proceeding or investigation, whether civil, criminal, administrative or investigative, whether arising before or after the Effective Time, arising out of or pertaining to the fact that such person is or was a director, officer or employee of Discover or any of its Subsidiaries and pertaining to matters or facts existing or occurring at or prior to the Effective Time, including the transactions contemplated by this Agreement; provided, that in the case of advancement of expenses, any Discover Indemnified Party to whom expenses are advanced provides an undertaking to repay such advances if it is ultimately determined that such Discover Indemnified Party is not entitled to indemnification.

-66-

(b) For a period of six (6) years after the Effective Time, the Surviving Entity shall cause to be maintained in effect the current policies of directors’ and officers’ liability insurance maintained by Discover (provided, that the Surviving Entity may substitute therefor policies with a substantially comparable insurer of at least the same coverage and amounts containing terms and conditions that are no less advantageous to the insured) with respect to claims against the present and former officers and directors of Discover and any of its Subsidiaries arising from facts or events which occurred at or before the Effective Time; provided, however, that the Surviving Entity shall not be obligated to expend, on an annual basis, an amount in excess of 300% of the current annual premium paid as of the date hereof by Discover for such insurance (the “Premium Cap”), and if such premiums for such insurance would at any time exceed the Premium Cap, then the Surviving Entity shall cause to be maintained policies of insurance which, in the Surviving Entity’s good faith determination, provide the maximum coverage available at an annual premium equal to the Premium Cap. In lieu of the foregoing, Capital One or Discover, in consultation with, but only upon the consent of Capital One, may (and at the request of Capital One, Discover shall use its reasonable best efforts to) obtain at or prior to the Effective Time a six (6)-year “tail” policy under Discover’s existing directors’ and officers’ insurance policy providing equivalent coverage to that described in the preceding sentence if and to the extent that the same may be obtained for an amount that, in the aggregate, does not exceed the Premium Cap.

(c) The provisions of this Section 6.7 shall survive the Effective Time and are intended to be for the benefit of, and shall be enforceable by, each Discover Indemnified Party and his or her heirs and representatives, each of whom shall be express third-party beneficiaries of this Section 6.7. If the Surviving Entity or any of its successors or assigns (i) consolidates with or merges into any other person and is not the continuing or surviving entity of such consolidation or merger, or (ii) transfers all or substantially all of its assets or deposits to any other person or engages in any similar transaction, then in each such case, the Surviving Entity will cause proper provision to be made so that the successors and assigns of the Surviving Entity will expressly assume the obligations set forth in this Section 6.7. The obligations of the Surviving Entity or any of its successors under this Section 6.7 shall not be terminated or modified after the Effective Time in a manner so as to adversely affect any Discover Indemnified Party or any other person entitled to the benefit of this Section 6.7 without the prior written consent of the affected Discover Indemnified Party or affected person.

6.8 Additional Agreements. In case at any time after the Effective Time any further action is necessary or desirable to carry out the purposes of this Agreement (including any merger between a Subsidiary of Capital One, on the one hand, and a Subsidiary of Discover, on the other hand) or to vest the Surviving Entity with full title to all properties, assets, rights, approvals, immunities and franchises of any of the parties to the Mergers or the Bank Merger, the proper officers and directors of each party to this Agreement and their respective Subsidiaries shall take all such necessary action as may be reasonably requested by Capital One.

-67-

6.9 Advice of Changes. Capital One and Discover shall each promptly advise the other party of any effect, change, event, circumstance, condition, occurrence or development (i) that has had or would reasonably be expected to have, either individually or in the aggregate, a Material Adverse Effect on it or (ii) that it believes would or would reasonably be expected to cause or constitute a material breach of any of its representations, warranties, obligations, covenants or agreements contained herein that reasonably could be expected to give rise, individually or in the aggregate, to the failure of a condition in Article VII; provided, that any failure to give notice in accordance with the foregoing with respect to any breach shall not be deemed to constitute a violation of this Section 6.9 or the failure of any condition set forth in Section 7.2 or 7.3 to be satisfied, or otherwise constitute a breach of this Agreement by the party failing to give such notice, in each case unless the underlying breach would independently result in a failure of the conditions set forth in Section 7.2 or 7.3 to be satisfied; and provided, further, that the delivery of any notice pursuant to this Section 6.9 shall not cure any breach of, or noncompliance with, any other provision of this Agreement or limit the remedies available to the party receiving such notice.

6.10 Dividends. After the date of this Agreement, each of Capital One and Discover shall coordinate with the other the declaration of any dividends in respect of Capital One Common Stock and Discover Common Stock and the record dates and payment dates relating thereto, it being the intention of the parties hereto that holders of Discover Common Stock shall not receive two dividends, or fail to receive one dividend, in any quarter with respect to their shares of Discover Common Stock and any shares of Capital One Common Stock any such holder receives in exchange therefor in the Merger.

6.11 Stockholder Litigation. Each party shall give the other party prompt notice of any stockholder litigation against such party or its directors or officers relating to the transactions contemplated by this Agreement. Each party shall give the other party the opportunity to participate (at the other party’s expense) in the defense or settlement of any such litigation. Each party shall give the other party the right to review and comment on all filings or responses to be made in connection with any such litigation, and will in good faith take such comments into account. No party shall agree to settle any such litigation without the other party’s prior written consent, which consent shall not be unreasonably withheld, conditioned or delayed; provided, that a party shall not be obligated to consent to any settlement which does not include a full release of such party and its Affiliates or which imposes an injunction or other equitable relief after the Effective Time upon the Surviving Entity or any of its Affiliates.

6.12 Board Representation. Capital One shall take all appropriate action so that, as of the Effective Time, the number of directors constituting the Board of Directors of Capital One shall be increased by three (3) for a total of fifteen (15) directors, and three (3) current directors of Discover, determined by mutual agreement of Discover and Capital One, shall be appointed to the Board of Directors of Capital One (the “Discover Directors”).

6.13 Acquisition Proposals.

(a) Each party agrees that it will not, will cause each of its Subsidiaries not to and will cause its and their respective officers, directors and employees not to, and will use its reasonable best efforts to cause its agents, advisors and representatives (collectively, “Representatives”) not to, directly or indirectly, (i) initiate, solicit, knowingly encourage or knowingly facilitate any inquiries or proposals with respect to any Acquisition Proposal, (ii)

-68-

engage or participate in any negotiations with any person concerning any Acquisition Proposal, (iii) provide any confidential or nonpublic information or data to, or have or participate in any discussions with any person relating to any Acquisition Proposal or (iv) unless this Agreement has been terminated in accordance with its terms, approve or enter into any term sheet, letter of intent, commitment, memorandum of understanding, agreement in principle, acquisition agreement, merger agreement or other agreement (whether written or oral, binding or non-binding) (other than a confidentiality agreement referred to and entered into in accordance with this Section 6.13) in connection with or relating to any Acquisition Proposal. Notwithstanding the foregoing, in the event that after the date of this Agreement and prior to the receipt of the Requisite Capital One Vote, in the case or Capital One, or the Requisite Discover Vote, in the case of Discover, a party receives an unsolicited bona fide written Acquisition Proposal, such party may, and may permit its Subsidiaries and its and its Subsidiaries’ Representatives to, furnish or cause to be furnished confidential or nonpublic information or data and participate in such negotiations or discussions with the person making the Acquisition Proposal if the Board of Directors of such party concludes in good faith (after receiving the advice of its outside counsel, and with respect to financial matters, its financial advisors) that failure to take such actions would be more likely than not to result in a violation of its fiduciary duties under applicable law; provided, that, prior to furnishing any confidential or nonpublic information permitted to be provided pursuant to this sentence, such party shall have entered into a confidentiality agreement with the person making such Acquisition Proposal on terms no less favorable to it than the Confidentiality Agreement, which confidentiality agreement shall not provide such person with any exclusive right to negotiate with such party. Each party will, and will cause its Representatives to, immediately cease and cause to be terminated any activities, discussions or negotiations conducted before the date of this Agreement with any person other than Discover or Capital One, as applicable, with respect to any Acquisition Proposal. Each party will promptly (within twenty-four (24) hours) advise the other party following receipt of any Acquisition Proposal or any inquiry which could reasonably be expected to lead to an Acquisition Proposal, and the substance thereof (including the terms and conditions of and the identity of the person making such inquiry or Acquisition Proposal), will provide the other party with an unredacted copy of any such Acquisition Proposal and any draft agreements, proposals or other materials received in connection with any such inquiry or Acquisition Proposal, and will keep the other party apprised of any related developments, discussions and negotiations on a current basis, including any amendments to or revisions of the terms of such inquiry or Acquisition Proposal. Each party shall use its reasonable best efforts to enforce any existing confidentiality or standstill agreements to which it or any of its Subsidiaries is a party in accordance with the terms thereof.

(b) Nothing contained in this Agreement shall prevent a party or its Board of Directors from complying with Rule 14d-9 and Rule 14e-2 under the Exchange Act with respect to an Acquisition Proposal; provided, that such rules will in no way eliminate or modify the effect that any action pursuant to such rules would otherwise have under this Agreement.

6.14 Public Announcements. Discover and Capital One agree that the initial press release with respect to the execution and delivery of this Agreement shall be a release mutually agreed to by the parties. Thereafter, each of the parties agrees that no public release or announcement or statement concerning this Agreement or the transactions contemplated hereby shall be issued by any party without the prior written consent of the other party (which consent shall not be unreasonably withheld, conditioned or delayed), except (i) as required by applicable

-69-

law or the rules or regulations of any applicable Governmental Entity or stock exchange to which the relevant party is subject, in which case the party required to make the release or announcement shall consult with the other party about, and allow the other party reasonable time to comment on, such release or announcement in advance of such issuance or (ii) for such releases, announcements or statements that are consistent with other such releases, announcements or statements made after the date of this Agreement in compliance with this Section 6.14.

6.15 Change of Method. Discover and Capital One shall be empowered, upon their mutual agreement, at any time prior to the Effective Time, to change the method or structure of effecting the transactions contemplated by this Agreement (including the provisions of Article I), if and to the extent they both deem such change to be necessary, appropriate or desirable; provided, however, that no such change shall (i) alter or change the Exchange Ratio or the number of shares of Capital One Common Stock received by holders of Discover Common Stock in exchange for each share of Discover Common Stock or the treatment of the Discover Preferred Stock, (ii) adversely affect the Tax treatment of Discover’s stockholders or Capital One’s stockholders pursuant to this Agreement, (iii) adversely affect the Tax treatment of Discover or Capital One pursuant to this Agreement or (iv) materially impede or delay the consummation of the transactions contemplated by this Agreement in a timely manner. The parties agree to reflect any such change in an appropriate amendment to this Agreement executed by both parties in accordance with Section 9.1.

6.16 Restructuring Efforts. If either Discover or Capital One shall have failed to obtain the Requisite Discover Vote or the Requisite Capital One Vote at the duly convened Discover Meeting or Capital One Meeting, as applicable, or any adjournment or postponement thereof, each of the parties shall in good faith use its reasonable best efforts to negotiate a restructuring of the transactions contemplated by this Agreement (it being understood that neither party shall have any obligation to alter or change any material terms, including the Exchange Ratio, the treatment of the Discover Preferred Stock or the amount or kind of the consideration to be issued to holders of the capital stock of Discover as provided for in this Agreement or any term that would adversely affect the tax treatment of the transactions contemplated hereby in a manner adverse to such party or its stockholders) and/or resubmit this Agreement and the transactions contemplated hereby (or as restructured pursuant to this Section 6.16) to its respective stockholders for adoption or approval.

6.17 Takeover Statutes. None of Discover, Capital One, Mergers Sub or their respective Boards of Directors shall take any action that would cause any Takeover Statute to become applicable to this Agreement, the Mergers, or any of the other transactions contemplated hereby, and each shall take all necessary steps to exempt (or ensure the continued exemption of) the Mergers and the other transactions contemplated hereby from any applicable Takeover Statute now or hereafter in effect. If any Takeover Statute may become, or may purport to be, applicable to the transactions contemplated hereby, each party and the members of their respective Boards of Directors will grant such approvals and take such actions as are necessary so that the transactions contemplated by this Agreement may be consummated as promptly as practicable on the terms contemplated hereby and otherwise act to eliminate or minimize the effects of any Takeover Statute on any of the transactions contemplated by this Agreement, including, if necessary, challenging the validity or applicability of any such Takeover Statute.

-70-

6.18 Treatment of Discover Indebtedness. Upon the Second Effective Time, Capital One and/or its Subsidiaries shall assume the due and punctual performance and observance of the covenants and other obligations to be performed by Discover and/or its Subsidiaries under the definitive documents governing the indebtedness and other instruments related thereto of Discover and/or its Subsidiaries, and the due and punctual payment of the principal of (and premium, if any) and interest on the notes or other instruments governed thereby. In connection therewith, Capital One and Discover shall cooperate and use reasonable best efforts to execute and deliver (and cause their respective Subsidiaries to execute and deliver, if applicable) any supplemental indentures, officer’s certificates or other documents, and the parties hereto shall cooperate and use reasonable best efforts to provide any opinion of counsel required to make such assumption effective as of the Second Effective Time.

6.19 Exemption from Liability Under Section 16(b). Discover and Capital One agree that, in order to most effectively compensate and retain Discover Insiders, both prior to and after the Effective Time, it is desirable that Discover Insiders not be subject to a risk of liability under Section 16(b) of the Exchange Act to the fullest extent permitted by applicable law in connection with the conversion of shares of Discover Common Stock and Discover Preferred Stock into shares of Capital One Common Stock and New Capital One Preferred Stock in the Mergers and the conversion of Discover Equity Awards into corresponding Capital One Equity Awards in the Merger, and for that compensatory and retentive purpose agree to the provisions of this Section 6.19. Discover shall deliver to Capital One in a reasonably timely fashion prior to the Effective Time accurate information regarding those officers and directors of Discover subject to the reporting requirements of Section 16(a) of the Exchange Act (the “Discover Insiders”), and the Board of Directors of Capital One and of Discover, or a committee of non-employee directors thereof (as such term is defined for purposes of Rule 16b-3(d) under the Exchange Act), shall reasonably promptly thereafter, and in any event prior to the Effective Time, take all such steps as may be required to cause (in the case of Discover) any dispositions of Discover Common Stock, Discover Preferred Stock or Discover Equity Awards by the Discover Insiders, and (in the case of Capital One) any acquisitions of Capital One Common Stock, New Capital One Preferred Stock, or Capital One Equity Awards by any Discover Insiders who, immediately following the Mergers, will be officers or directors of the Surviving Entity subject to the reporting requirements of Section 16(a) of the Exchange Act, in each case pursuant to the transactions contemplated by this Agreement, to be exempt from liability pursuant to Rule 16b-3 under the Exchange Act to the fullest extent permitted by applicable law.

ARTICLE VIII

TERMINATION AND AMENDMENT

8.1 Termination. This Agreement may be terminated at any time prior to the Effective Time, whether before or after receipt of the Requisite Discover Vote or the Requisite Capital One Vote:

(a) by mutual written consent of Capital One and Discover;

-74-

(b) by either Capital One or Discover if any Governmental Entity that must grant a Requisite Regulatory Approval has denied approval of the Mergers or the Bank Merger and such denial has become final and nonappealable or any Governmental Entity of competent jurisdiction shall have issued a final and nonappealable order, injunction, decree or other legal restraint or prohibition permanently enjoining or otherwise prohibiting or making illegal the consummation of the Mergers or the Bank Merger, unless the failure to obtain a Requisite Regulatory Approval shall be due to the failure of the party seeking to terminate this Agreement to perform or observe the obligations, covenants and agreements of such party set forth herein;

(c) by either Capital One or Discover if the Merger shall not have been consummated on or before February 19, 2025 (as it may be extended pursuant to this Section 8.1(c), the “Termination Date”), unless the failure of the Closing to occur by such date shall be due to the failure of the party seeking to terminate this Agreement to perform or observe the obligations, covenants and agreements of such party set forth herein; provided, that, if on such date, any of the conditions to the Closing set forth in (A) Section 7.1(c) or (B) Section 7.1(e) (in the case of clause (B), to the extent related to a Requisite Regulatory Approval) shall not have been satisfied or waived on or prior to such date, but all other conditions set forth in Article VII shall have been satisfied or waived (or in the case of conditions that by their nature can only be satisfied at the Closing, shall then be capable of being satisfied if the Closing were to take place on such date), then the Termination Date shall be automatically extended to May 19, 2025, and such date shall become the Termination Date for purposes of this Agreement;

(ii) In the event that this Agreement is terminated by Capital One pursuant to Section 8.1(f), then Discover shall pay Capital One, by wire transfer of same-day funds, the Termination Fee within two (2) business days of the date of termination.

(c) (i) In the event that after the date of this Agreement and prior to the termination of this Agreement, a bona fide Acquisition Proposal shall have been communicated to or otherwise made known to the Board of Directors or senior management of Capital One or shall have been made directly to the stockholders of Capital One or any person shall have publicly announced (and not withdrawn at least two (2) business days prior to the Capital One Meeting) an Acquisition Proposal, in each case with respect to Capital One and (A) (x) thereafter this Agreement is terminated by either Capital One or Discover pursuant to Section 8.1(c) without the Requisite Capital One Vote having been obtained (and all other conditions set forth in Section 7.1 and Section 7.2 were satisfied or were capable of being satisfied prior to such termination) or (y) thereafter this Agreement is terminated by Discover pursuant to Section 8.1(d) as a result of a willful breach, and (B) prior to the date that is twelve (12) months after the date of such termination, Capital One enters into a definitive agreement or consummates a transaction with respect to an Acquisition Proposal (whether or not the same Acquisition Proposal as that referred to above), then Capital One shall, on the earlier of the date it enters into such definitive agreement and the date of consummation of such transaction, pay Discover the Termination Fee by wire transfer of same-day funds; provided, that for purposes of this Section 8.2(c)(i), all references in the definition of Acquisition Proposal to “twenty-five percent (25%)” shall instead refer to “fifty percent (50%).”

(d) Notwithstanding anything to the contrary herein, but without limiting the right of any party to recover liabilities or damages to the extent permitted herein, in no event shall either party be required to pay the Termination Fee more than once.

(e) Each of Capital One and Discover acknowledges that the agreements contained in this Section 8.2 are an integral part of the transactions contemplated by this Agreement, and that, without these agreements, the other party would not enter into this Agreement; accordingly, if Capital One or Discover, as the case may be, fails promptly to pay the amount due pursuant to this Section 8.2, and, in order to obtain such payment, the other party commences a suit which results in a judgment against the non-paying party for the Termination Fee or any portion thereof, such non-paying party shall pay the costs and expenses of the other party (including attorneys’ fees and expenses) in connection with such suit. In addition, if Capital One or Discover, as the case may be, fails to pay the amounts payable pursuant to this Section 8.2, then such party shall pay interest on such overdue amounts (for the period commencing as of the date that such overdue amount was originally required to be paid and ending on the date that such overdue amount is actually paid in full) at a rate per annum equal to the “prime rate” published in The Wall Street Journal on the date on which such payment was required to be made for the period commencing as of the date that such overdue amount was originally required to be paid and ending on the date that such overdue amount is actually paid in full.

Each of the parties hereto represents and warrants that this Agreement has been duly authorized, executed and delivered by such party and (assuming due authorization, execution and delivery by the other party) constitutes a valid and binding obligation of such party, enforceable against it in accordance with the terms hereof (except in all cases as such enforceability may be limited by bankruptcy, insolvency, fraudulent transfer, moratorium, reorganization or similar laws of general applicability affecting the rights of creditors generally and the availability of equitable remedies).

Subject in all respects to Section 6.1 of the Holding Company Agreement, each of the parties shall use its reasonable best efforts to take, or cause to be taken, all actions necessary, proper or advisable to comply promptly with all legal requirements that may be imposed on such party or its Subsidiaries with respect to the Bank Merger and, subject to the conditions set forth in Section 10 hereof, to consummate the transactions contemplated by this Agreement.

None of the representations, warranties or agreements in this Agreement, or in any instrument delivered pursuant to this Agreement, shall survive the Effective Time or valid termination of this Agreement.

This Agreement embodies the entire agreement and understanding of the Banks with respect to the transactions contemplated hereby, and supersedes all other prior commitments, arrangements or understandings, both oral and written, among the Banks with respect to the subject matter hereof, other than the Holding Company Agreement.

The provisions of this Agreement are intended to be interpreted and construed in a manner so as to make such provisions valid, binding and enforceable. If any provision of this Agreement is determined to be partially or wholly invalid, illegal or unenforceable, then such provision shall be deemed to be modified or restricted to the extent necessary to make such provision valid, binding and enforceable; or, if such provision cannot be modified or restricted in a manner so as to make such provision valid, binding and enforceable, then such provision shall be deemed to be excised from this Agreement and the validity, binding effect and enforceability of the remaining provisions of this Agreement shall not be affected or impaired in any manner.

No waiver, amendment, modification or change of any provision of this Agreement shall be effective unless and until made in writing and signed by the Banks. No waiver, forbearance or failure by any Bank of its rights to enforce any provision of this Agreement shall constitute a waiver or estoppel of such Bank’s right to enforce any other provision of this Agreement or a continuing waiver by such Bank of compliance with any provision hereof.

Each Bank agrees that it will bring any action or proceeding in respect of any claim arising out of or related to this Agreement or the transactions contemplated hereby exclusively in the Delaware Court of Chancery and any state appellate court therefrom within the State of Delaware or, if the Delaware Court of

Chancery declines to accept jurisdiction over a particular matter, any federal or state court of competent jurisdiction located in the State of Delaware (the “Chosen Courts”), and, solely in connection with claims arising under this Agreement or the transactions that are the subject of this Agreement, (i) irrevocably submits to the exclusive jurisdiction of the Chosen Courts, (ii) waives any objection to laying venue in any such action or proceeding in the Chosen Courts, (iii) waives any objection that the Chosen Courts are an inconvenient forum or do not have jurisdiction over any party and (iv) agrees that service of process upon such party in any such action or proceeding will be effective if notice is given in accordance with this Section 13.

Except to the extent federal law is applicable, this Agreement shall be governed by and construed and enforced in accordance with the laws of the State of Delaware without regard to conflicts of laws principles. EACH OF THE PARTIES HERETO WAIVES ANY RIGHT TO REQUEST A TRIAL BY JURY IN ANY LITIGATION WITH RESPECT TO THIS AGREEMENT AND REPRESENTS THAT COUNSEL HAS BEEN CONSULTED SPECIFICALLY AS TO THIS WAIVER.

Subject to the preceding sentence, this Agreement will be binding upon, inure to the benefit of, and be enforceable by, the Banks’ respective successors and permitted assigns. Unless otherwise expressly stated herein, this Agreement shall not benefit or create any right of action in or on behalf of any person or entity other than the Banks.

This Agreement may be executed in counterparts (including by facsimile or optically scanned electronic mail attachment), each of which shall be deemed to be original, but all of which together shall constitute one and the same instrument.
