Item 1.01 Entry into a Material Definitive Agreement

On August 17, 2016, United Bankshares, Inc. (“United”) and its wholly-owned subsidiary, UBV Holding Company, LLC (“UBV”) entered into an Agreement and Plan of Reorganization (the “Agreement”) with Cardinal Financial Corporation (“Cardinal”), a Virginia corporation headquartered in Tysons Corner, Virginia.

In accordance with the Agreement, Cardinal shall merge with and into UBV (the “Merger”). At which time, Cardinal shall cease to exist and UBV shall survive and continue to exist as a Virginia limited liability company. United may at any time prior to the effective time of the Merger change the method of effecting the combination with Cardinal subject to certain conditions contained in the Agreement.

The Agreement provides that upon consummation of the Merger, each outstanding share of common stock of Cardinal will be converted into the right to receive 0.71 shares of United common stock, par value $2.50 per share.

Pursuant to the Agreement, at the effective time of the Merger, each outstanding Cardinal stock option granted under a Cardinal stock plan, whether vested or unvested as of the date of the Agreement, shall vest and convert into an option to acquire United common stock adjusted based on the 0.71 exchange ratio. Also, at the effective time of the Merger, each restricted stock award granted under a Cardinal stock plan that is unvested or contingent and outstanding immediately prior to the effective time of the Merger shall fully vest and be converted into the right to receive shares of United common stock based on the 0.71 exchange ratio.

At the effective time of the Merger, Cardinal Bank, a wholly-owned subsidiary of Cardinal, will merge with and into United Bank, a wholly-owned indirect subsidiary of United (the “Bank Merger”). United Bank will survive the Bank Merger and continue to exist as a Virginia banking corporation.

Consummation of the Merger is subject to approval of the shareholders of United and Cardinal, the receipt of all required regulatory approvals, as well as other customary conditions.

The foregoing description of the Agreement does not purport to be complete and is qualified in its entirety by reference to the full text of the Agreement, a copy of which is attached as Exhibit 2.1 to this Current Report on Form 8-K and is incorporated herein by reference. The Agreement has been attached as an exhibit to provide investors and security holders with information regarding its terms. It is not intended to provide any other financial information about United or its subsidiaries or affiliates. The representations, warranties and covenants contained in the Agreement were made only for purposes of that agreement and as of specific dates, are solely for the benefit of the parties to the Agreement, may be subject to limitations agreed upon by the parties, including being qualified by confidential disclosures made for the purposes of allocating contractual risk between the parties to the Agreement instead of establishing these matters as facts, and may be subject to standards of materiality applicable to the parties that differ from those applicable to investors. Investors should not rely on the representations, warranties, or covenants or any description thereof as characterizations of the actual state of facts or condition of United or any of its subsidiaries or affiliates. Moreover, information concerning the subject matter of the representations, warranties, and covenants may change after the date of the Agreement, which subsequent information may or may not be fully reflected in public disclosures by United.

These forward-looking statements include, but are not limited to, statements about (i) the benefits of a merger (the “Merger”) between Cardinal Financial Corporation (“Cardinal”) and United Bankshares, Inc. (“United”), including future financial and operating results, cost savings enhancements to revenue and accretion to reported earnings that may be realized from the Merger; (ii) United’s and Cardinal’s plans, objectives, expectations and intentions and other statements contained in this press release that are not historical facts; and (iii) other statements identified by words such as “expects,” “anticipates,” “intends,” “plans,” “believes,” “seeks,” “estimates,” “targets,” “projects,” or words of similar meaning generally intended to identify forward-looking statements. These forward-looking statements are based upon the current beliefs and expectations of the respective managements of United and Cardinal and are inherently subject to significant business, economic and competitive uncertainties and contingencies, many of which are beyond the control of United and Cardinal. In addition, these forward-looking statements are subject to assumptions with respect to future business strategies and decisions that are subject to change. Actual results may differ materially from the anticipated results discussed in these forward-looking statements because of possible uncertainties.

The following factors, among others, could cause actual results to differ materially from the anticipated results or other expectations expressed in the forward-looking statements: (1) the businesses of United and Cardinal may not be combined successfully, or such combination may take longer, be more difficult, time-consuming or costly to accomplish than expected; (2) the expected growth opportunities or cost savings from the Merger may not be fully realized or may take longer to realize than expected; (3) deposit attrition, operating costs, customer losses and business disruption following the Merger, including adverse effects on relationships with employees, may be greater than expected; (4) the regulatory approvals required for the Merger may not be obtained on the proposed terms or on the

anticipated schedule; (5) the stockholders of United and Cardinal may fail to approve the Merger; (6) legislative or regulatory changes, including changes in accounting standards, may adversely affect the businesses in which United and Cardinal are engaged; (7) changes in the interest rate environment may compress margins and adversely affect net interest income; (8) results may be adversely affected by continued diversification of assets and adverse changes to credit quality; (9) competition from other financial services companies in United’s and Cardinal’s markets could adversely affect operations; and (10) an economic slowdown could adversely affect credit quality and loan originations. Additional factors, that could cause actual results to differ materially from those expressed in the forward-looking statements are discussed in Cardinal’s and United’s reports (such as Annual Reports on Form 10-K, Quarterly Reports on Form 10-Q and Current Reports on Form 8-K) filed with the Securities and Exchange Commission and available on the SEC’s Internet site (http://www.sec.gov).

United and Cardinal caution that the foregoing list of factors is not exclusive. All subsequent written and oral forward-looking statements concerning the proposed transaction or other matters attributable to United or Cardinal or any person acting on their behalf are expressly qualified in their entirety by the cautionary statements above. United and Cardinal do not undertake any obligation to update any forward-looking statement to reflect circumstances or events that occur after the date the forward-looking statements are made.

ARTICLE IV

Consideration; Exchange Procedures

4.01 Merger Consideration. Subject to the provisions of this Agreement, at the Effective Time, automatically by virtue of the Merger and without any action on the part of any Person:

(a) Merger Consideration. Each holder of a share of Cardinal Common Stock (other than United and its Subsidiaries, in each case except for shares held by them in a fiduciary capacity or as a result of debts previously contracted) shall receive in respect thereof, subject to the limitations set forth in this Agreement, 0.71 shares (“Exchange Ratio”) of United Common Stock (the “Merger Consideration”).

(b) Outstanding United Stock. Each share of United Common Stock issued and outstanding immediately prior to the Effective Time shall remain issued and outstanding and unaffected by the Merger.

(c) Merger Sub Equity Interests. Each equity interest of Merger Sub outstanding immediately prior to the Effective Time shall remain outstanding and unaffected by the Merger, and no consideration shall be issued in exchange therefor.

4.02 Rights as Stockholders; Stock Transfers. At the Effective Time, holders of Cardinal Common Stock shall cease to be, and shall have no rights as, stockholders of Cardinal, other than to receive the Merger Consideration (if so provided in Section 4.01(a)) and any dividend or other distribution with respect to such Cardinal Common Stock with a record date occurring prior to the Effective Time and the consideration provided under this Article IV. After the Effective Time, there shall be no transfers on the stock transfer books of Cardinal or the Surviving Entity of shares of Cardinal Common Stock.

4.03 Fractional Shares. Notwithstanding any other provision hereof, no fractional shares of United Common Stock and no certificates or scrip therefore, or other evidence of ownership thereof, will be issued in the Merger; instead, United shall pay to each holder of Cardinal Common Stock who would otherwise be entitled to a fractional share of United Common Stock (after taking into account all Old Certificates registered in the name of such holder or Book-Entry Shares held by such holder) an amount in cash (without interest) determined by multiplying such fraction by the average of the daily closing prices for the shares of United Common Stock for the 20 consecutive full trading days on which such shares are actually traded on the NASDAQ (as reported by The Wall Street Journal or, if not reported thereby, any other authoritative source) ending at the close of trading on the tenth trading day immediately preceding the Effective Date (such average, the “Average Closing Price”).

4.04 Exchange Procedures.

(a) At or prior to the Effective Time, United shall deposit, or shall cause to be deposited, with the Exchange Agent, for the benefit of the holders of certificates formerly representing shares of Cardinal Common Stock (“Old Certificates”) and holders of non-certificated shares of Cardinal Common Stock (“Book-Entry Shares”), for exchange in accordance with this Article IV, (i) non-certificated shares of United Common Stock (collectively, “United Book-Entry Shares”) and (ii) an amount of cash necessary for payments required by Section 4.03 (the “Exchange Fund”). The Exchange Fund will be distributed in accordance with the Exchange Agent’s normal and customary procedures established in connection with merger transactions.

11

(b) As soon as practicable after the Effective Time, and in no event later than five business days thereafter, the Exchange Agent shall mail to each holder of record of one or more Old Certificates or Book-Entry Shares a letter of transmittal (which shall specify that delivery shall be effected, and risk of loss and title to the Old Certificates or Book-Entry Shares shall pass, only upon delivery of the Old Certificates or Book-Entry Shares to the Exchange Agent) and instructions for use in effecting the surrender of the Old Certificates or Book-Entry Shares in exchange for United Book-Entry Shares, if any, that the holders of the Old Certificates or Book-Entry Shares are entitled to receive pursuant to Article IV, any cash in lieu of fractional shares into which the shares of Cardinal Common Stock represented by the Old Certificates or Book-Entry Shares shall have been converted pursuant to this Agreement. Upon proper surrender of an Old Certificate or Book-Entry Shares for exchange and cancellation to the Exchange Agent, together with such properly completed letter of transmittal, duly executed, the holder of such Old Certificates or Book-Entry Shares shall be entitled to receive in exchange therefor (i) a New Certificate representing that number of whole shares of United Common Stock that such holder has the right to receive pursuant to Article IV, if any, and (ii) a check representing the amount of any cash in lieu of fractional shares which such holder has the right to receive in respect of the Old Certificates or Book-Entry Shares surrendered pursuant to the provisions of this Article IV, and the Old Certificates or Book-Entry Shares so surrendered shall forthwith be cancelled.

(c) Neither the Exchange Agent, if any, nor any party hereto shall be liable to any former holder of Cardinal Common Stock for any amount properly delivered to a public official pursuant to applicable abandoned property, escheat or similar laws.

(d) No dividends or other distributions with respect to United Common Stock with a record date occurring after the Effective Time shall be paid to the holder of any unsurrendered Old Certificate or Book-Entry Shares representing shares of Cardinal Common Stock converted in the Merger into the right to receive shares of such United Common Stock until the holder thereof shall be entitled to receive United Book-Entry Shares in exchange therefore in accordance with the procedures set forth in this Section 4.04. After becoming so entitled in accordance with this Section 4.04, the record holder thereof also shall be entitled to receive any such dividends or other distributions by the Exchange Agent, without any interest thereon, which theretofore had become payable with respect to shares of United Common Stock such holder had the right to receive upon surrender of the Old Certificates or Book-Entry Shares.

(e) Any portion of the Exchange Fund that remains unclaimed by the stockholders of Cardinal on the business day after the one-year anniversary of the Effective Date shall be paid to United. Any stockholders of Cardinal who have not theretofore complied with this Article IV shall thereafter look only to United for payment of the Merger Consideration, cash in lieu of any fractional shares and unpaid dividends and distributions on United Common Stock deliverable in respect of each share of Cardinal Common Stock such stockholder holds as determined pursuant to this Agreement, in each case, without any interest thereon.

12

4.05 Anti-Dilution Provisions. In the event United changes (or establishes a record date for changing) the number of shares of United Common Stock issued and outstanding prior to the Effective Date as a result of a stock split, reverse stock split, stock dividend, reorganization, recapitalization or similar transaction with respect to the outstanding United Common Stock and the record date therefor shall be prior to the Effective Date, or shall establish a record date prior to the Effective Date with respect to any dividend or other distribution in respect of the United Common Stock other than a cash dividend consistent with past practice, the Exchange Ratio shall be proportionately adjusted to provide the holders of Cardinal Common Stock the same economic effect as contemplated by this Agreement prior to such event.

4.06 Equity-Based Awards.

(a) At the Effective Time, each outstanding option (each, a “Cardinal Stock Option”) to purchase shares of Cardinal Common Stock, whether vested or unvested, under any and all plans of Cardinal under which stock options have been granted (collectively, the “Cardinal Stock Plans”) shall vest pursuant to the terms thereof shall be converted into an option (each, a “Replacement Option”) to acquire, on the same terms and conditions as were applicable under such Cardinal Stock Option, the number of shares of United Common Stock equal to (a) the number of shares of Cardinal Common Stock subject to the Cardinal Stock Option multiplied by (b) the Exchange Ratio. Such product shall be rounded down to the nearest whole number. The exercise price per share (rounded up to the next whole cent) of each Replacement Option shall equal (y) the exercise price per share of shares of Cardinal Common Stock that were purchasable pursuant to such Cardinal Stock Option divided by (z) the Exchange Ratio. Notwithstanding the foregoing, each Cardinal Stock Option that is intended to be an “incentive stock option” (as defined in Section 422 of the Code) shall be adjusted in accordance with the requirements of Section 424 of the Code and all other options shall be adjusted in a manner that maintains the options exemption from Section 409A of the Code. At or prior to the Effective Time, Cardinal shall use its reasonable best efforts to obtain any necessary consents from optionees with respect to the Cardinal Stock Plans to permit replacement of the outstanding Cardinal Stock Options by United pursuant to this Section and to permit United to assume the Cardinal Stock Plans. Cardinal shall further take all action necessary to amend the Cardinal Stock Plans to eliminate automatic grants or awards thereunder following the Effective Time. At the Effective Time, United shall assume the Cardinal Stock Plans; provided that such assumption shall only be with respect to the Replacement Options and shall have no obligation to make any additional grants or awards under the Cardinal Stock Plans other than those grants or awards that have been made or accrued prior to the Effective Time. United shall file a post-effective amendment to the Registration Statement or an effective registration statement on Form S-8 (or other applicable form) with respect to the shares of United Common Stock subject to such Replacement Options, shall distribute a prospectus relating to such Form S-8, if applicable, and shall use reasonable commercial efforts to maintain the effectiveness of the Registration Statement or registration statement on Form S-8 for so long as such Replacement Options remain outstanding.

(b) At the Effective Time, each restricted stock award granted under a Cardinal Stock Plan (each, a “Cardinal Stock Award”) that is unvested or contingent and outstanding immediately prior to the Effective Time shall fully vest and shall be converted into the right to

13

receive, without interest, the Merger Consideration payable pursuant to Section 4.01, and the shares of Cardinal Common Stock subject to such Cardinal Stock Award will be treated in the same manner as all other shares of Cardinal Common Stock for such purposes.

4.07 Withholding Rights. United or the Exchange Agent, as the case may be, will be entitled to deduct and withhold from the consideration otherwise payable pursuant to this Agreement to any Person such amounts, if any, 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 and remitted to the appropriate Governmental Authority by or on behalf of United or the Exchange Agent, as the case may be, such amounts withheld will be treated for all purposes of this Agreement as having been paid to such Person in respect of which such deduction and withholding was made by United or the Exchange Agent, as the case may be.

There is no material pending or, to the knowledge of United, threatened legal action, suit or claim relating to the United Compensation and Benefit Plans other than routine claims for benefits. Neither United

36

nor any of its Subsidiaries has engaged in a transaction, or omitted to take any action, with respect to any United Compensation and Benefit Plan that would reasonably be expected to subject United or any of its Subsidiaries to a tax or penalty imposed by either Section 4975 of the Code or Section 502 of ERISA, assuming for purposes of Section 4975 of the Code that the taxable period of any such transaction expired as of the date hereof.

37

taken any action, or omitted to take any action, that has resulted, or would reasonably be expected to result, in the imposition of a lien under Section 412(n) of the Code or pursuant to ERISA.

(vi) United and its Subsidiaries do not maintain any United Compensation and Benefit Plans covering foreign Employees.

(vii) The consummation of the transactions contemplated by this Agreement would not, directly or indirectly (including, without limitation, as a result of any termination of employment prior to or following the Effective Time) reasonably be expected to (A) entitle any United Employee, United Consultant or United Director to any payment (including severance pay or similar compensation) or any increase in compensation, (B) result in the vesting or acceleration of any benefits under any United Compensation and Benefit Plan or (C) result in any material increase in benefits payable under any United Compensation and Benefit Plan.

(ix) As a result, directly or indirectly, of the transactions contemplated by this Agreement (including, without limitation, as a result of any termination of employment prior to or following the Effective Time), neither United nor Cardinal, or any of their respective Subsidiaries will be obligated to make a payment with respect to any person who is an employee, before the Effective Time, of United or any of its Subsidiaries, that would be characterized as an “excess parachute payment” to an individual who is a “disqualified individual” (as such terms are defined in Section 280G of the Code), without regard to whether such payment is reasonable compensation for personal services performed or to be performed in the future.

(x) Neither United nor any of its Subsidiaries has made any agreement, taken any action, or omitted to take any action, with respect to or as part of any United Compensation and Benefit Plan that is an operational failure under Section 409A of the Code or that would reasonably be expected to subject United or any of its Subsidiaries to any obligation to report any amount or withhold any amount as includable in income and subject to tax, interest or any penalty by any service provider to United or any of its Subsidiaries under Section 409A of

38

the Code or to pay any reimbursement or other payment to any service provider, as defined under Section 409A of the Code, respecting any such tax, interest or penalty under Section 409A of the Code.

(p) Environmental Matters. To United’s knowledge, neither the conduct nor operation of United or its Subsidiaries nor any condition of any property presently or previously owned, leased or operated by any of them (including, without limitation, in a fiduciary or agency capacity), or on which any of them holds a Lien, violates or violated Environmental Laws and to United’s knowledge no condition has existed or event has occurred with respect to any of them or any such property that, with notice or the passage of time, or both, is reasonably likely to result in liability under Environmental Laws. To United’s knowledge, neither United nor any of its Subsidiaries has received any notice from any person or entity that United or its Subsidiaries or the operation or condition of any property ever owned, leased, operated or held as collateral or in a fiduciary capacity by any of them are or were in violation of or otherwise are alleged to have liability under any Environmental Law, including, but not limited to, responsibility (or potential responsibility) for the cleanup or other remediation of any pollutants, contaminants, or hazardous or toxic wastes, substances or materials at, on, beneath or originating from any such property.

(a) Cardinal agrees to take, in accordance with applicable law and the Cardinal Certificate and the Cardinal Bylaws, all action necessary to convene an appropriate meeting of its stockholders to consider and vote upon the approval of this Agreement and any other matters required to be approved by Cardinal’s stockholders for consummation of the Merger (including any adjournment or postponement, the “Cardinal Meeting”), as promptly as practicable after the Registration Statement is declared effective. The Cardinal Board will recommend that the Cardinal stockholders approve and adopt the Agreement and the transactions contemplated hereby, provided that the Cardinal Board may fail to make such recommendation, or withdraw, modify or change any such recommendation, if the Cardinal Board, after having consulted with and considered the advice of outside counsel, has determined that the making of such recommendation, or the failure to withdraw, modify or change such recommendation, would be reasonably likely to constitute a breach of the fiduciary duties of the members of the Cardinal Board under applicable law.

(b) United agrees to take, in accordance with applicable law and the United Certificate and the United Bylaws, all action necessary to convene an appropriate meeting of its stockholders to consider and vote upon (i) the United Certificate Amendment and (ii) the issuance of the Merger Consideration pursuant to NASDAQ Listing Rule 5635 and pursuant to Sections 31D-6-621 and 31D-11-1104 of the WVBCA, with respect to issuing the Merger Consideration and approving the Merger, and any other matters required to be approved by United’s stockholders for consummation of the Merger and the transactions contemplated by the Agreement (including any adjournment or postponement, the “United Meeting”), as promptly as practicable after the Registration Statement is declared effective. The United Board will recommend that the United stockholders approve (i) the United Certificate Amendment and (ii) the issuance of the Merger Consideration and, as necessary, the transactions contemplated by the Agreement, provided that the United Board may fail to make such a recommendation, or

42

withdraw, modify or change any such recommendation, if the United Board, after having consulted with and considered the advice of outside counsel, has determined that the making of such recommendation, or the failure to withdraw, modify or change such recommendation, would be reasonably likely to constitute a breach of the fiduciary duties of the members of the United Board under applicable law.

(c) Cardinal and United shall use their reasonable best efforts to hold their respective stockholder meetings on the same date and as close in time to the Effective Date as reasonably practicable.

7.03 Registration Statement.

(a) United agrees to prepare a registration statement on Form S-4 (the “Registration Statement”) to be filed by United with the SEC in connection with the issuance of United Common Stock in the Merger (including the prospectus of United and proxy solicitation materials of United and Cardinal constituting a part thereof (the “Proxy Statement”) and all related documents). Cardinal and United agree to cooperate, and to cause their respective Subsidiaries, as applicable, to cooperate, with the other and its counsel and its accountants in the preparation of the Registration Statement and the Proxy Statement. United agrees to file the Registration Statement (including the Proxy Statement in preliminary form) with the SEC as promptly as reasonably practicable and in any event within 120 days from the date of this Agreement. Each of Cardinal and United agrees to use all reasonable efforts to cause the Registration Statement to be declared effective under the Securities Act as promptly as reasonably practicable after filing thereof. United also agrees to use all reasonable efforts to obtain, prior to the effective date of the Registration Statement, all necessary state securities law or “Blue Sky” permits and approvals required to carry out the transactions contemplated by this Agreement. Each of United and Cardinal agrees to furnish to the other party all information concerning itself, its Subsidiaries, officers, directors and stockholders and such other matters as may be reasonably necessary or advisable or as may be reasonably requested in connection with the Registration Statement, Proxy Statement or any other statement, filing, notice or application made by or on behalf of United, Cardinal or their respective Subsidiaries, as applicable, to any Governmental Authority in connection with the Merger and the other transactions contemplated by this Agreement. Cardinal shall have the right to review and consult with United and approve the form of, and any characterization of such information included in, the Registration Statement prior to its being filed with the SEC.

(b) Each of Cardinal and United agrees, as to itself and its Subsidiaries and affiliates, as applicable, that none of the information supplied or to be supplied by it for inclusion or incorporation by reference in (i) the Registration Statement will, at the time the Registration Statement and each amendment or supplement thereto, if any, becomes effective under the Securities Act, contain any untrue statement of a material fact or omit to state any material fact required to be stated therein or necessary to make the statements therein not misleading, and (ii) the Proxy Statement and any amendment or supplement thereto will, at the date of mailing to stockholders and at the time of the Cardinal Meeting, as the case may be, contain any untrue statement of a material fact or omit to state any material fact required to be stated therein or necessary to make the statements therein not misleading or any statement which, in the light of the circumstances under which such statement is made, will be false or misleading with respect to any material fact, or which will omit to state any material fact necessary in order to make the statements therein not false or misleading or necessary to correct any statement in any earlier statement in the Proxy Statement or any amendment or supplement thereto. Each of Cardinal and

43

United further agrees that if it shall become aware prior to the date of the Cardinal Meeting or United Meeting, as the case may be, of any information furnished by it that would cause any of the statements in the Proxy Statement to be false or misleading with respect to any material fact, or to omit to state any material fact necessary to make the statements therein not false or misleading, to promptly inform the other party thereof and to take the necessary steps to correct the Proxy Statement.

(c) United agrees to advise Cardinal, promptly after United receives notice thereof, of the time when the Registration Statement has become effective or any supplement or amendment has been filed, of the issuance of any stop order or the suspension of the qualification of United Stock for offering or sale in any jurisdiction, of the initiation or threat of any proceeding for any such purpose, or of any request by the SEC for the amendment or supplement of the Registration Statement or for additional information.

7.04 Access; Information.

(a) Each of Cardinal and United agrees that upon reasonable notice and subject to applicable laws relating to the exchange of information, it shall afford the other party and the other party’s officers, employees, counsel, accountants and other authorized representatives, such access during normal business hours throughout the period prior to the Effective Time to the books, records (including, without limitation, Tax Returns and work papers of independent auditors), properties, personnel and to such other information as any party may reasonably request and, during such period, it shall furnish promptly to such other party (i) a copy of each material report, schedule and other document filed by it pursuant to the requirements of federal or state securities laws, and (ii) all other information concerning the business, properties and personnel of it as the other may reasonably request. Neither United or its Subsidiaries nor Cardinal or its Subsidiaries shall be required to provide access to or to disclose information where such access or disclosure would jeopardize the attorney-client privilege of United, Cardinal or their respective Subsidiaries, as the case may be, or contravene any applicable law or regulation or binding contract, agreement or arrangement entered into prior to the date of this Agreement; and in any such event, the parties will make appropriate substitute disclosure arrangements.

(b) Each of Cardinal and United agrees that it will not, and will cause its representatives not to, use any information obtained pursuant to this Section 7.04 (as well as any other information obtained prior to the date hereof in connection with the entering into of this Agreement) for any purpose unrelated to the consummation of the Merger and the other transactions contemplated by this Agreement. Subject to the requirements of law, each party will keep confidential, and will cause its representatives to keep confidential, all information and documents obtained pursuant to this Section 7.04 (as well as any other information obtained prior to the date hereof in connection with the entering into of this Agreement) unless such information (i) was already known to such party, (ii) becomes available to such party from other sources not known by such party to be bound by a confidentiality obligation, (iii) is disclosed with the prior written approval of the party to which such information pertains or (iv) is or becomes readily ascertainable from published information or trade sources. In the event that this Agreement is terminated or the transactions contemplated by this Agreement shall otherwise fail

44

to be consummated, each party shall promptly cause all copies of documents or extracts thereof containing information and data as to another party hereto to be returned to the party that furnished the same. No investigation by either party of the business and affairs of the other shall affect or be deemed to modify or waive any representation, warranty, covenant or agreement in this Agreement, or the conditions to either party’s obligation to consummate the transactions contemplated by this Agreement.

(c) During the period from the date of this Agreement to the Effective Time, each party shall promptly furnish the other with copies of all monthly and other interim financial statements produced in the ordinary course of business as the same shall become available.

(d) The provisions of this Section 7.04 are in addition to, and not in lieu of, those certain confidentiality agreements dated May 23, 2016 and August 10, 2016, between United and Cardinal (the “Confidentiality Agreement”), the terms of which are specifically confirmed.

7.05 Acquisition Proposals. Cardinal agrees that it shall not, and shall cause its Subsidiaries and its officers, directors, agents, advisors and affiliates not to, solicit or encourage inquiries or proposals with respect to, or engage in any negotiations concerning, or provide any confidential information to, or have any discussions with any person relating to, any Acquisition Proposal. It shall immediately cease and cause to be terminated any activities, discussions or negotiations conducted prior to the date of this Agreement with any parties other than United with respect to any of the foregoing and shall use its reasonable best efforts to enforce any confidentiality or similar agreement relating to an Acquisition Proposal. Cardinal will inform United promptly of all relevant details of any inquiries or contacts by third parties relating to the possible disposition of the business or the capital stock of Cardinal or any merger, change or control or other business combination involving Cardinal. Notwithstanding the foregoing, nothing contained in this Section 7.05 shall prohibit Cardinal, prior to the Cardinal Meeting and subject to compliance with the other terms of this Section 7.05, from furnishing nonpublic information to, or entering into discussions or negotiations with, any Person that makes an unsolicited, bona fide written Acquisition Proposal with respect to Cardinal or any of its Significant Subsidiaries (that did not result from a breach of this Section 7.05), if, and only to the extent that (i) the Cardinal Board concludes in good faith, after consultation with and based upon the advice of outside legal counsel, that the failure to take such actions would be reasonably likely to constitute a breach of its fiduciary duties to its shareholders under applicable law, (ii) before taking such actions, Cardinal receives from such Person an executed confidentiality agreement providing for reasonable protection of confidential information, which confidentiality agreement shall not provide such person or entity with any exclusive right to negotiate with Cardinal and shall contain terms and conditions no less favorable to Cardinal with respect to confidentiality than the Confidentiality Agreement, and (iii) the Cardinal Board concludes in good faith, after consultation with its outside legal counsel and financial advisors, that the Acquisition Proposal constitutes or is reasonably likely to result in a Superior Proposal. Cardinal shall promptly notify United in writing of Cardinal’s receipt of any such Acquisition Proposal or inquiry, the material terms and conditions thereof, the identity of the person making such Acquisition Proposal or inquiry, and will keep United apprised of any related developments, discussions and negotiations on a current basis. Cardinal agrees that any violation of the restrictions set forth in this Section 7.05 by any representative of Cardinal shall be deemed a breach of this Section 7.05 by Cardinal.

45

7.06 Takeover Laws. No party hereto shall take any action that would cause the transactions contemplated by this Agreement to be subject to requirements imposed by any Takeover Law and each of them shall take all necessary steps within its control to exempt (or ensure the continued exemption of) the transactions contemplated by this Agreement from any applicable Takeover Law, as now or hereafter in effect.

7.07 Exemption from Liability Under Section 16(b). United and Cardinal agree that, in order to most effectively compensate and retain certain directors and officers of Cardinal in connection with the Merger, both prior to and after the Effective Time, it is desirable that the directors and officers of Cardinal not be subject to a risk of liability under Section 16(b) of the Exchange Act, and for that compensatory and retentive purposes agree to the provisions of this Section 7.07. The United Board, or a committee of “Non-Employee Directors” (as such term is defined for purposes of Rule 16b-3(d) under the Exchange Act) thereof, shall promptly, and in any event prior to the Effective Time, take all such steps as may be necessary or appropriate to cause any dispositions of Cardinal Common Stock, Cardinal Stock Awards, Cardinal Stock Options or acquisitions (and any subsequent dispositions) of United Common Stock or Replacement Options by the directors and officers of Cardinal, who, immediately following the Merger, will be directors and officers of United 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 Section 16(b) under the Exchange Act to the fullest extent permitted by applicable law.

7.08 Regulatory Applications.

(a) United and Cardinal and their respective Subsidiaries and affiliates, as applicable, (a) shall cooperate and use their respective reasonable best efforts to prepare all documentation, to effect all filings and to obtain all permits, consents, approvals and authorizations of all third parties and Governmental Authorities necessary to consummate the transactions contemplated by this Agreement and (b) covenant and agree that none of the information supplied or to be supplied by such party and any of its Subsidiaries and affiliates, as applicable, for inclusion in any filings with Governmental Authorities will, at the respective time such filing is made be false or misleading with respect to any material fact, or omit to state any material fact necessary to make the statements therein, in light of the circumstances under which they are made not misleading. Each Party shall use its reasonable efforts to resolve objections, if any, which may be asserted with respect to the Merger under any applicable law, regulation or decree, including agreeing to divest any assets, deposits, lines of business or branches; provided, that United shall not be required to agree to any condition or take any action if such agreements or the taking of such action is reasonably likely to result in any conditions or requirements applicable either before or after the Effective Time that the United Board reasonably determines in good faith would have a Material Adverse Effect on United and its Subsidiaries taken as a whole taking into account the consummation of the Merger in making such determination (a “Materially Burdensome Regulatory Condition”). Each of United and Cardinal shall have the right to review in advance, and to the extent practicable each will consult with the other, in each case subject to applicable laws relating to the exchange of information, with respect to, all

46

material written information submitted to any third party or any Governmental Authority in connection with the transactions contemplated by this Agreement. In exercising the foregoing right, each of the parties hereto agrees to act reasonably and as promptly as practicable and, in any event, United shall make all necessary filings and provide any necessary notices within 120 days of the date of this Agreement. Each party hereto agrees that it will consult with the other party hereto with respect to the obtaining of all material permits, consents, approvals and authorizations of all third parties and Governmental Authorities necessary or advisable to consummate the transactions contemplated by this Agreement and each party will keep the other party apprised of the status of material matters relating to completion of the transactions contemplated hereby, including advising the other party upon receiving any communication from a Governmental Authority the consent or approval of which is required for the consummation of the Merger and the other transactions contemplated by this Agreement that causes such party to believe that there is a reasonable likelihood that any required consent or approval from a Governmental Authority will not be obtained or that the receipt of such consent or approval may be materially delayed (a “Regulatory Communication”). Upon the receipt of a Regulatory Communication, without limiting the scope of the foregoing paragraphs, United shall, to the extent permitted by applicable law (i) promptly advise Cardinal of the receipt of any substantive communication from a Governmental Authority with respect to the transactions contemplated hereby, (ii) provide Cardinal with a reasonable opportunity to participate in the preparation of any response thereto and the preparation of any other substantive submission or communication to any Governmental Authority with respect to the transactions contemplated hereby and to review any such response, submission or communication prior to the filing or submission thereof, and (iii) provide Cardinal with the opportunity to participate in any meetings or substantive telephone conversations that United or its Subsidiaries or their respective representatives may have from time to time with any Governmental Authority with respect to the transactions contemplated by this Agreement.

(b) Each party agrees, upon request, to furnish the other party with all information concerning itself, its Subsidiaries, directors, officers and stockholders and such other matters as may be reasonably necessary or advisable in connection with any filing, notice or application made by or on behalf of such other party or any of its Subsidiaries to any third party or Governmental Authority.

7.09 Indemnification.

(a) Following the Effective Date and for a period of six years thereafter, United shall indemnify, defend and hold harmless the present directors, officers and employees of Cardinal and its Subsidiaries (each, an “Indemnified Party”) against all costs or expenses (including reasonable attorneys’ fees), judgments, fines, losses, claims, damages or liabilities (collectively, “Costs”) incurred in connection with any claim, action, suit, proceeding or investigation, whether civil, criminal, administrative or investigative, arising out of actions or omissions occurring at or prior to the Effective Time (including the transactions contemplated by this Agreement), whether asserted or claimed prior to, at or after the Effective Time to the fullest extent that Cardinal is permitted or required to indemnify (and advance expenses to) its directors and officers under the laws of the Commonwealth of Virginia, the Cardinal Certificate, the

47

Cardinal Bylaws and any agreement as in effect on the date hereof; provided that any determination required to be made with respect to whether an officer’s, director’s or employee’s conduct complies with the standards set forth under Virginia law, the Cardinal Certificate, the Cardinal Bylaws and any agreement shall be made by independent counsel (which shall not be counsel that provides material services to United) selected by United and reasonably acceptable to such officer or director. United shall comply with any indemnification agreements between Cardinal or its Subsidiaries on the one hand, and their respective directors and officers on the other hand; provided, however, that each of Cardinal and its Subsidiaries, as applicable, agrees to exercise its reasonable best efforts to obtain amendments to each indemnification agreement applicable to it prior to the Effective Date so that terms of any such agreement aligns with the time periods set forth in this Section 7.09.

(b) For a period of six years from and after the Effective Time, United shall (i) maintain in effect (A) the current provisions regarding indemnification of and the advancement of expenses to Indemnified Parties contained in the Cardinal Certificate and Cardinal Bylaws (or comparable organizational documents) of each of Cardinal and its Subsidiaries and (B) any indemnification agreements of Cardinal and its Subsidiaries with or for the benefit of any Indemnified Parties existing on the date hereof, and (ii) indemnify the Indemnified Parties to the fullest extent permitted by applicable law. For purposes of the foregoing: (i) in the event any claim is asserted within the six year period during which Cardinal and its Subsidiaries, (A) all such rights in respect of any such claim shall continue until disposition thereof and (B) the Indemnified Party shall be entitled to advancement of expenses within five business days following receipt of any such claim involving such Indemnified Party; and (ii) any determination required to be made with respect to whether an Indemnified Party’s conduct complies with the standards set forth under VSCA, the Cardinal Certificate or Cardinal Bylaws or any such agreement, as the case may be, for purposes of the allowance of indemnification or advancement of expenses, shall be made by independent legal counsel selected by such Indemnified Party and reasonably acceptable to United. The fees and expenses of such independent legal counsel shall be paid for by United.

(c) For a period of six years from the Effective Time, United shall use its reasonable best efforts to provide that portion of director’s and officer’s liability insurance that serves to reimburse the present and former officers and directors of Cardinal or any of its Subsidiaries (determined as of the Effective Time) (as opposed to Cardinal) with respect to claims against such directors and officers arising from facts or events which occurred before the Effective Time, which insurance shall contain at least the same coverage and amounts, and contain terms and conditions no less advantageous, as that coverage currently provided by Cardinal; provided, that in no event shall United be required to expend, on an annual basis, more than 200% of the current annual amount expended by Cardinal (the “Insurance Amount”) to maintain or procure such directors and officers insurance coverage; provided, further, that if United is unable to maintain or obtain the insurance called for by this Section 7.09(c), United shall use its reasonable best efforts to obtain as much comparable insurance as is available for the Insurance Amount; provided, further, that officers and directors of Cardinal or any Subsidiary may be required to make application and provide customary representations and warranties to United’s insurance carrier for the purpose of obtaining such insurance.

48

(d) Any Indemnified Party wishing to claim indemnification under Section 7.09(a), upon learning of any claim, action, suit, proceeding or investigation described above, shall promptly notify United thereof; provided that the failure so to notify shall not affect the obligations of United under Section 7.09(a) unless and to the extent that United is actually prejudiced as a result of such failure.

(e) If United or any of its successors or assigns shall consolidate with or merge into any other entity and shall not be the continuing or surviving entity of such consolidation or merger or shall transfer all or substantially all of its assets to any entity, then and in each case, proper provision shall be made so that the successors and assigns of United shall assume the obligations set forth in this Section 7.09.

(f) The provisions of this Section 7.09, (i) shall survive the Effective Time and are intended to be for the benefit of, and shall be enforceable by, each Indemnified Party and his or her heirs and representatives, and (ii) are in addition to, and not in substitution for, any other rights to indemnification or contribution that any such person may have by agreement or otherwise.

7.10 Benefit Plans.

(a) At and following the Effective Time (i) United shall provide employees of Cardinal and its Subsidiaries with employee benefit plans substantially similar to those provided to similarly situated employees of United, except with respect to the United Pension Plan, (ii) United shall cause any and all pre-existing condition limitations (to the extent such limitations did not apply to a pre-existing condition under the Compensation and Benefit Plans) and eligibility waiting periods under group health plans to be waived with respect to such employees and their eligible dependents, and (iii) all employees of Cardinal and its Subsidiaries shall receive credit for years of service with Cardinal, its Subsidiaries and their predecessors prior to the Effective Time for purposes of eligibility and vesting (but not for purposes of benefit accrual other than accrual for vacation; provided, that, in accordance with United’s policies, no vacation or paid time off shall thereafter be carried over into a subsequent calendar year except that employees who are retained by United shall be permitted to carry over vacation until the end of 2018 and employees who are not retained by United shall be paid for unused vacation) under United’s benefit plans, except with respect to the United Pension Plan. All employees of Cardinal and its Subsidiaries and their eligible dependents will receive credit for co-payments, deductibles and out-of-pocket maximums satisfied by such employees and dependents under the Compensation and Benefit Plans. Except as provided in this Agreement, United shall maintain Cardinal’s and its Subsidiaries’ existing employee benefit plans until such time as United has provided similar plans to employees of Cardinal and its Subsidiaries as contemplated in the preceding sentence. Employees of Cardinal and its Subsidiaries shall not be entitled to accrual of benefits or allocation of contributions under United’s benefit plans based on years of service with Cardinal, its Subsidiaries and their predecessors prior to the Effective Date, except with respect to any vacation accrual.

49

(b) Except for employees of Cardinal and its Subsidiaries with individual agreements that provide for payment of severance under certain circumstances (who will be paid severance only in accordance with such agreements and shall not have a right to employer-paid outplacement services), United agrees that each employee of Cardinal and its Subsidiaries who is involuntarily terminated by United or any of its Subsidiaries (other than for cause) on or within the time period set forth on Section 7.10(b) of Cardinal’s Disclosure Schedule, shall receive (i) a severance payment equal to the amounts set forth on Section 7.10(b) of Cardinal’s Disclosure Schedule, but only if such employee does not have rights to a severance payment under an employment agreement, in which case no severance payment shall be made to such employee hereunder, and (ii) outplacement services through the date that is set forth on Section 7.10(b) of Cardinal’s Disclosure Schedule by an outplacement agency selected by United.

(c) Cardinal shall cause its 401(k) plan to be fully vested and terminated effective immediately prior to or upon the Effective Time, in accordance with applicable law and regulations, and Cardinal shall pursue, in United’s sole discretion, the receipt of a favorable determination letter from the IRS relating to such termination. Each employee of Cardinal and its Subsidiaries that is a participant in Cardinal’s 401(k) plan, and that becomes an eligible employee of United or its Subsidiaries following the Effective Time, shall be eligible to participate in United’s 401(k) plan as soon as administratively practical, in accordance with the terms and conditions of United’s 401(k) plan, after the Effective Time, and, account balances under Cardinal’s terminated 401(k) plan will be eligible for distribution or rollover, in accordance with the terms and conditions of the United 401(k) plan and applicable law and regulation, including direct rollover of cash and, provided that Cardinal’s terminated 401(k) plan was validly amended prior to termination to provide for (A) roll out of promissory notes, (B) a period of time during which plan termination does not cause immediate loan default, (C) in-kind distribution of promissory notes, and (D) such other plan provisions as are required for rollout of promissory notes, direct rollover of promissory notes to United’s 401(k) plan, for each such employee in his or her discretion. Any other former employee of Cardinal or its Subsidiaries that is employed by United or its Subsidiaries after the Effective Time shall be eligible to be a participant in United’s 401(k) plan upon complying with eligibility requirements. For purposes of administering United’s 401(k) plan, service with Cardinal and its Subsidiaries shall be deemed to be service with United for participation and vesting purposes, but not for purposes of benefit accrual. United shall take all required actions to assume as of the Effective Time all obligations under Cardinal’s Executive Deferred Income Plan, the George Mason Mortgage, LLC Executive Deferred Income Plan and Cardinal’s Non-Employee Directors Deferral Plan; provided, that United shall be under no obligation to permit further contributions to such plans after the Effective Time.

(d) Each of United, Cardinal and the key employees of Cardinal, as the case may be, will enter into agreements concerning their employment with United and related matters after the Effective Time in accordance with the terms and conditions set forth in Section 7.10(d) of the Cardinal Disclosure Schedule. At and following the Effective Time, United shall honor, and United shall be obligated to perform, or shall cause its Subsidiaries to honor and perform, in accordance with their terms and applicable law, the contractual rights of Employees, Consultants and Directors of Cardinal and its Subsidiaries existing as of the Effective Time.

50

7.11 Notification of Certain Matters. Each of Cardinal and United shall give prompt notice to the other of any fact, event or circumstance known to it that (i) is reasonably likely, individually or taken together with all other facts, events and circumstances known to it, to result in any Material Adverse Effect with respect to it or (ii) would cause or constitute a material breach of any of its representations, warranties, covenants or agreements contained herein.

7.12 Directors.

(a) United shall take all appropriate action so that as of the Effective Time the number of directors constituting the United Board shall be increased by one and Bernard H. Clineburg shall be appointed as a director of United. United will nominate Bernard H. Clineburg for election as a director at the annual meeting of United immediately following the Effective Time and solicit proxies for Bernard H. Clineburg in the same manner as it does for all other members of United’s slate of directors in connection with such meeting.

7.14 Operating Functions. Cardinal shall cooperate with United and Merger Sub in connection with planning for the efficient and orderly combination of the parties and the operation of United and Merger Sub (including the former operations of Cardinal) after the Merger, and in preparing for the consolidation of appropriate operating functions to be effective on the Effective Time or such later date as United may decide. Notwithstanding the foregoing, (a) neither United nor Merger Sub shall under any circumstance be permitted to exercise control of Cardinal prior to the Effective Time, (b) Cardinal shall not be under any obligation to act in a manner that could reasonably be deemed to constitute anti-competitive behavior under federal or state antitrust laws and (c) Cardinal shall not be required to agree to any material obligation that is not contingent upon the consummation of the Merger.

7.15 Assumption of TRUPs. United acknowledges that Cardinal Statutory Trust I and UFBC Capital Trust I hold subordinated debentures issued by Cardinal and has issued preferred securities which are intended to be “qualified trust preferred securities” as defined in applicable regulatory capital guidelines, or which are eligible for such treatment as grandfathered trust preferred securities. United agrees that at the Effective Time, it shall expressly assume all of Cardinal’s obligations under the indentures relating to such subordinated debentures (including, without limitation, being substituted for Cardinal) and execute any and all documents, instruments and agreements, including any supplemental indentures, guarantees, or declarations of trust required by said indentures, the subordinated debentures or the trust preferred securities issued by Cardinal Statutory Trust I and UFBC Capital Trust I, or as may reasonably be requested by the trustees thereunder, and thereafter shall perform all of Cardinal’s obligations with respect to the subordinated debentures and the trust preferred securities issued by Cardinal Statutory Trust I and UFBC Capital Trust I (the “TRUPs Assumption”).

(b) Breach. At any time prior to the Effective Time, by United or Cardinal (provided that the party seeking termination is not then in material breach of any representation, warranty, covenant or other agreement contained herein), if its board of directors so determines by vote of a majority of the members of its entire board of directors, in the event of either: (i) a breach by the other party of any representation or warranty contained herein (subject to the standard set forth in Section 6.02), which breach cannot be or has not been cured within 30 days after the giving of written notice to the breaching party of such breach; or (ii) a material breach by the other party of any of the covenants or agreements contained herein, which material breach cannot be or has not been cured within 30 days after the giving of written notice to the breaching party of such breach.

(f) No Approval. By Cardinal or United, if its board of directors so determines by a vote of a majority of the members of its entire board of directors, in the event (i) (A) final action has been taken by any Governmental Authority whose approval is required for consummation of the Merger and the other transactions contemplated by this Agreement, which final action has become nonappealable and does not approve this Agreement or the transactions contemplated hereby, or such Governmental Authority has approved of this Agreement or the transactions contemplated hereby with a Materially Burdensome Regulatory Condition, or (B) any Governmental Authority whose approval or nonobjection is required in connection with this Agreement and the transactions contemplated hereby has stated that it will not issue the required approval or nonobjection, or (ii) any stockholder approval required by Section 8.01(a) herein is not obtained at the Cardinal Meeting or the United Meeting.

(g) Failure to Recommend, Etc.

55

(i) Decline in United Common Stock Price. By Cardinal, if the Cardinal Board so determines by a vote of the majority of the members of the entire Cardinal Board, at any time during the five-day period commencing with the Determination Date, if both of the following conditions are satisfied:

(i) The number obtained by dividing the Determination Date Average Closing Price by the Starting Price (as defined below) (the “United Ratio”) shall be less than 0.80; and

(ii) (x) the United Ratio shall be less than (y) the number obtained by dividing the Final Index Price by the Index Price on the Starting Date (each as defined below) and subtracting 0.15 from the quotient in this clause (ii) (y) (such number in this clause (ii) (y) being referred to herein as, the “Index Ratio”);

subject, however, to the following three sentences. If Cardinal elects to exercise its termination right pursuant to this Section 9.01(i), it shall give written notice to United (provided that such notice of election to terminate may be withdrawn at any time within the aforementioned five-day period). During the five-day period commencing with its receipt of such notice, United shall have the option to increase the consideration to be received by the holders of Cardinal Common Stock hereunder, by adjusting the Exchange Ratio (calculated to the nearest one one-thousandth) to equal the lesser of (x) a number (rounded to the nearest one one-thousandth) obtained by dividing (A) the product of the Starting Price, 0.80 and the Exchange Ratio (as then in effect) by (B) the Determination Date Average Closing Price and (y) a number (rounded to the nearest one one-thousandth) obtained by dividing (A) the product of the Index Ratio and the Exchange Ratio (as then in effect) by (B) the United Ratio. If United so elects within such five-day period, it shall give prompt written notice to Cardinal of such election and the revised Exchange Ratio, whereupon no termination shall have occurred pursuant to this Section 9.01(i) and this Agreement shall remain in effect in accordance with its terms (except as the Exchange Ratio shall have been so modified).

For purposes of this Section 9.01(i), the following terms shall have the meanings indicated:

“Determination Date” shall mean the latest of (i) the date on which the last approval, consent or waiver of any Governmental Authority required to permit the consummation of the transactions contemplated by this Agreement is received and all statutory waiting periods in respect thereof shall have expired; (ii) the latest date on which the stockholder approvals of both Cardinal and United set forth in Section 7.02 are received; or (iii) the date scheduled to integrate Cardinal’s data processing systems with United’s data processing systems, so long as all conditions set forth in Article VIII have been satisfied (which date shall be identified by the parties in writing as soon as practicable after the date hereof).

56

(a) In the event that, (i) this Agreement shall be terminated by Cardinal pursuant to Section 9.01(h), then Cardinal shall pay United promptly (but in no event later than two business days after the date of termination of this Agreement by Cardinal) a fee of $36,000,000 (the “Cardinal Fee”), which amount shall be payable in immediately available funds or (ii) this Agreement is terminated by United pursuant to Section 9.01(g)(i), and prior to that date that is 12 months after such termination, Cardinal or any of its Subsidiaries enters into any Acquisition Agreement or any Acquisition Proposal is consummated (regardless of whether such Acquisition Proposal is consummated before or after termination of this Agreement), then Cardinal shall pay United the Cardinal Fee on the earlier of such date of execution or consummation, which amount shall be payable in immediately available funds. For the purposes of this Section, “Acquisition Agreement” shall mean any letter of intent, memorandum of understanding, agreement in principle, acquisition agreement, merger agreement, or other similar agreement constituting or related to, or which is intended to or would be reasonably likely to lead to, any Acquisition Proposal. For purposes of the foregoing, the term “Acquisition Proposal” shall have the meaning set forth in the definition of “Acquisition Proposal” in Section 1.01 except that the references to “24.99%” shall be deemed to be references to “50.01%.” In no event shall Cardinal be required to pay the Cardinal Fee on more than one occasion.

57

(b) In the event that this Agreement shall be terminated by United or Cardinal pursuant to Sections 9.01(c) or 9.01(f)(i), but only if (i) (A) the delay in the Effective Time giving rise to the termination right under Section 9.01(c), or (B) the action or statement by a Governmental Authority giving rise to the termination right under Section 9.01(f)(i), as applicable, arises solely because United does not satisfy the condition to approval of a Governmental Authority requiring it to raise or obtain capital, in accordance with the terms required by the applicable Governmental Authority, (ii) the following conditions set forth in Article VIII have been or are reasonably likely to be satisfied: Sections 8.01(a) (but only with respect to the vote of stockholders of Cardinal), 8.01(c) (excluding for this purpose, any rule, regulation, judgment, order, decree or other order of a Governmental Authority with respect to an approval contemplated under Section 8.01(b)), 8.03(a) and 8.03(b), (iii) Cardinal has not breached its obligations under Section 7.03, and (iv) United does not otherwise have a right to terminate the Agreement pursuant to Sections 9.01(b) or 9.01(d), then United shall pay Cardinal promptly (but in no event later than two business days after the date of termination of this Agreement) a fee of $13,500,000 (the “United Fee”, together with the Cardinal Fee, the “Fees”, and each individually, a “Fee”), which amount shall be payable in immediately available funds.

(c) The agreements contained in paragraphs (a) and (b) of this Section 9.03 shall be deemed an integral part of the transactions contemplated by this Agreement, and without such agreements the parties would not have entered into this Agreement. A Fee payable pursuant to paragraphs (a) and (b) of this Section 9.03 shall be the sole and exclusive remedy of United and Cardinal, respectively, in the event such Fee is payable as specified therein. In the event that Cardinal or United, as applicable, shall fail to pay a Fee when due, then such party shall pay such Fee plus the costs and expenses actually incurred by the other party (including, without limitation, fees and expenses of counsel) in connection with the collection of such Fee under the enforcement of this Section 9.03, together with interest on such unpaid Fee and costs and expenses, commencing on the date that such Fee became due, at a rate equal to the rate of interest publicly announced by Citibank, N.A., from time to time, in the City of New York, as such bank’s Base Rate plus 2.00%.

Exhibit A

PLAN OF MERGER

merging

CARDINAL FINANCIAL CORPORATION,

a Virginia bank holding company

with and into

UBV HOLDING COMPANY, LLC,

a Virginia bank holding company

1. Merger. Cardinal Financial Corporation (“Cardinal”), a Virginia bank holding company incorporated pursuant to the Virginia Stock Corporation Act (the “VSCA”), shall upon the Effective Time (as defined in Section 2.a) be merged (the “Merger”) with and into UBV Holding Company, LLC (“UBV”), a Virginia bank holding company organized pursuant to the Virginia Limited Liability Company Act (“VLLCA”), a disregarded entity for income tax purposes and a wholly-owned subsidiary of United Bankshares, Inc. (“United”), a West Virginia bank holding company incorporated pursuant to the West Virginia Business Corporation Act, in accordance with the applicable provisions of the VSCA and the VLLCA. As a result of the Merger, the separate corporate existence of Cardinal shall cease and UBV shall continue as the surviving entity (the “Surviving Entity”) following the Merger. The existence of UBV, with all its rights, privileges, immunities, powers and franchises, shall continue unaffected and unimpaired by the Merger.

2. Effective Time; Effects of the Merger.

a. The Merger shall become effective at the latest of: (i) the issuance by the Virginia State Corporation Commission (the “SCC”) of a certificate of merger relating to the Merger; and (ii) the time set forth in articles of merger relating to the Merger to be filed with the SCC; such time referred to herein as the “Effective Time.”

b. At the Effective Time, the Merger shall have the effects set forth in Section 13.1-721 of the VSCA and Section 13.1-1070 of the VLLCA. Without limiting the generality of the foregoing, and subject thereto, at the Effective Time the separate corporate existence of Cardinal shall cease and all of the properties, rights, powers, privileges, franchises, patents, trademarks, licenses, registrations and other assets of every kind and description of Cardinal shall be vested in, and all debts, liabilities and obligations of Cardinal shall be the obligation of, UBV as the Surviving Entity, all without further act or deed, in accordance with the applicable provisions of the VSCA and the VLLCA.

3. Articles of Organization. The articles of organization, as amended, of UBV in effect at the Effective Time shall be the articles of incorporation of the Surviving Entity, until the same shall thereafter be altered, amended or repealed as provided therein or by applicable law.

A-1

4. Operating Agreement. The operating agreement, as amended, of UBV in effect at the Effective Time shall be the operating agreement of the Surviving Entity, until the same shall thereafter be altered, amended or repealed as provided therein or by applicable law.

5. Board of Directors; Officers. From and after the Effective Time, the directors of UBV immediately prior to the Effective Time shall be the directors of the Surviving Entity until their successors are duly appointed or elected. From and after the Effective Time, the officers and managers of UBV immediately prior to the Effective Time shall be the officers of the Surviving Entity until their successors are duly appointed or elected.

6. Manner and Basis of Converting Securities. At the Effective Time, by virtue of the Merger and without any action on the part of United, UBV, Cardinal or any holder of any shares of capital stock of United, UBV or Cardinal:

a. Cardinal Common Stock.

i. At the Effective Time, each holder of a share of common stock, $1.00 par value per share, of Cardinal (“Cardinal Common Stock”) (excluding shares of Cardinal Common Stock held by United, UBV or any United or UBV Subsidiary, in each case other than in a fiduciary capacity or as a results of debts previously contracted, which shares shall (i) not be exchanged for shares of United Common Stock and (ii) be canceled and extinguished for no consideration, and shall be marked “canceled in merger” as of the Effective Time) outstanding immediately prior to the Effective Time shall automatically be converted into and exchangeable for the right to receive 0.71 (the “Exchange Ratio”) shares of common stock, $2.50 par value per share, of United (“United Common Stock”, and together with cash in lieu of fractional shares as provided in Section 6.b below, collectively, the “Merger Consideration”).

ii. Effective as of the Effective Time, each share of Cardinal Common Stock issued and outstanding immediately prior to the Effective Time (other than Excluded Shares, as defined in Section 6.f) shall no longer be outstanding and shall automatically be canceled and retired and cease to exist, and each holder of certificates that immediately prior to the Effective Time evidenced shares of Cardinal Common Stock (each, a “Cardinal Certificate”), and each holder of non-certificated shares of Cardinal Common Stock (“Cardinal Book-Entry Shares”) shall cease to have any rights with respect thereto, except the right to receive the Merger Consideration therefor upon surrender of such Cardinal Certificate or Cardinal Book-Entry Shares in accordance with Section 7.

b. No Fractional Shares. No fractional shares of United Common Stock shall be issued in respect of shares of Cardinal Common Stock that are to be converted in the Merger into the right to receive shares of United Common Stock. Holders of Cardinal Common Stock entitled to fractional shares shall be entitled to receive in lieu of any fractional share of United Common Stock to which such holder would otherwise have been entitled pursuant to Sections 6.a and 7 an amount in cash (without interest) (the “Cash Consideration”), rounded to the nearest whole cent (with one-half cent being rounded upwards), equal to the product obtained by multiplying (i) the fractional share of United Common Stock to which such holder would otherwise be entitled (after taking into account all shares of Cardinal Common Stock held by

A-2

such holder immediately prior to the Effective Time) by (ii) the average of the daily closing prices for United Common Stock for the 20 consecutive full trading days on which such shares are actually traded on the NASDAQ (as reported by The Wall Street Journal or, if not reported thereby, any other authoritative source) ending at the close of trading on the tenth trading day immediately preceding the Effective Date.

c. Adjustment for Certain Transactions in United Common Stock. If, on or after the date of the Agreement and Plan of Reorganization, by and between United and Cardinal, dated as of August 17, 2016 (the “Merger Agreement”), and prior to the Effective Time, United changes (or establishes a record date for changing) the number of shares of United Common Stock issued and outstanding as a result of a stock split, reverse stock split, stock dividend, reorganization, recapitalization or similar transaction with respect to the then outstanding United Common Stock, or establishes a record date prior to the Effective Date with respect to any dividend or distribution in respect of United Common Stock other than a cash dividend consistent with past practice, the Exchange Ratio shall be proportionately adjusted to provide holders of Cardinal Common Stock the same economic effect as contemplated by the Merger Agreement prior to such action.

d. United Common Stock and UBV Equity Interests. Each share of United Common Stock and each equity interest of UBV outstanding immediately prior to the Effective Time shall be unchanged, and shall continue to represent an issued and outstanding share of United Common Stock and an outstanding equity interest of UBV, respectively.

e. Cardinal Common Stock Held by United and UBV. All shares of Cardinal Common Stock owned directly or indirectly by United, UBV or any of United’s or UBV’s respective wholly owned subsidiaries (other than shares held in a fiduciary capacity or as a result of debts previously contracted) shall be cancelled and retired and shall not represent capital stock of the Surviving Entity and shall not be exchanged for the Merger Consideration; such cancelled and retired shares are referred to herein as, the “Excluded Shares”.

f. Cardinal Equity-Based Awards.

(i) At the Effective Time, each outstanding option (each, a “Cardinal Stock Option”) to purchase shares of Cardinal Common Stock, whether vested or unvested, under any and all plans of Cardinal under which stock options have been granted (collectively, the

A-3

“Cardinal Stock Plans”) shall vest pursuant to the terms thereof and shall be converted an option (each, a “Replacement Option”) to acquire, on the same terms and conditions as were applicable under such Cardinal Stock Option, the number of shares of United Common Stock equal to (a) the number of shares of Cardinal Common Stock subject to the Cardinal Stock Option multiplied by (b) the Exchange Ratio. Such product shall be rounded down to the nearest whole number. The exercise price per share (rounded up to the next whole cent) of each Replacement Option shall equal (y) the exercise price per share of shares of Cardinal Common Stock that were purchasable pursuant to such Cardinal Stock Option divided by (z) the Exchange Ratio. Notwithstanding the foregoing, each Cardinal Stock Option that is intended to be an “incentive stock option” (as defined in Section 422 of the Code) shall be adjusted in accordance with the requirements of Section 424 of the Code and all other options shall be adjusted in a manner that maintains the options exemption from Section 409A of the Code. At or prior to the Effective Time, Cardinal shall use its reasonable best efforts to obtain any necessary consents from optionees with respect to the Cardinal Stock Plans to permit replacement of the outstanding Cardinal Stock Options by United pursuant to this Section and to permit United to assume the Cardinal Stock Plans. Cardinal shall further take all action necessary to amend the Cardinal Stock Plans to eliminate automatic grants or awards thereunder following the Effective Time. At the Effective Time, United shall assume the Cardinal Stock Plans; provided that such assumption shall only be with respect to the Replacement Options and shall have no obligation to make any additional grants or awards under the Cardinal Stock Plans other than those grants or awards that have been made or accrued prior to the Effective Time. United shall file a post-effective amendment to the Registration Statement or an effective registration statement on Form S-8 (or other applicable form) with respect to the shares of United Common Stock subject to such Replacement Options, shall distribute a prospectus relating to such Form S-8, if applicable, and shall use reasonable commercial efforts to maintain the effectiveness of the Registration Statement or registration statement on Form S-8 for so long as such Replacement Options remain outstanding.

(ii) At the Effective Time, each restricted stock award granted under a Cardinal Stock Plan (each, a “Cardinal Stock Award”) that is unvested or contingent and outstanding immediately prior to the Effective Time shall fully vest and shall be converted into the right to receive, without interest, the Merger Consideration payable pursuant to Section 6(a), and the shares of Cardinal Common Stock subject to such Cardinal Stock Award will be treated in the same manner as all other shares of Cardinal Common Stock for such purposes.

7. Cardinal Common Stock Exchange Procedures.

a. Exchange Agent; Merger Consideration. United shall appoint its transfer agent, Computershare Limited, or, with the written consent of Cardinal, which shall not be unreasonably withheld, another agent independent of and unaffiliated with United, UBV or Cardinal (the “Exchange Agent”), for the purpose of exchanging Cardinal Certificates and Cardinal Book-Entry Shares for the Merger Consideration. At or prior to the Effective Time, United shall deposit, or cause to be deposited, with the Exchange Agent, for the benefit of the holders of Cardinal Common Stock and for exchange in accordance with this Plan of Merger, or shall duly authorize and direct issuance by the Exchange Agent in accordance with this Section 7 of, (i) certificates, or, at United’s option, evidence of shares in book-entry form, representing the shares of United Common Stock, and (ii) an amount of cash necessary to pay the Cash Consideration.

A-4

b. Surrender of Cardinal Certificates and Cardinal Book-Entry Shares. United shall cause the Exchange Agent, not later than five Business Days after the Effective Time, to mail to each holder of one or more Cardinal Certificates or of Cardinal Book-Entry Shares a form letter of transmittal for return to the Exchange Agent containing instructions for use in effecting the surrender of the Cardinal Certificates and Cardinal Book-Entry Shares in exchange for the Merger Consideration into which the Cardinal Common Stock represented by such Cardinal Certificates and Cardinal Book-Entry Shares shall have been converted as a result of the Merger. The letter of transmittal shall specify that delivery shall be effected, and risk of loss and title to the Cardinal Certificates and Cardinal Book-Entry Shares shall pass, only upon delivery of the Cardinal Certificates and Cardinal Book-Entry Shares to the Exchange Agent. Upon proper surrender of a Cardinal Certificate or Cardinal Book-Entry Shares for exchange and cancellation to the Exchange Agent or compliance with the provisions of Section 7.e, together with a properly completed letter of transmittal, duly executed, the holder of such Cardinal Certificate or Cardinal Book-Entry Shares shall be entitled to receive in exchange therefor the Merger Consideration and the Cardinal Certificate and/or Cardinal Book-Entry Shares so surrendered shall be cancelled. Any portion of the Merger Consideration that remains unclaimed by the holders of Cardinal Common Stock on the business day after the one-year anniversary of the Effective Date shall be paid to United. Any holders of Cardinal Common Stock who have not theretofor complied with this Section 7.b. shall thereafter look only to United for payment of the Merger Consideration, cash in lieu of fractional shares and unpaid dividends and distributions on United Common Stock deliverable in respect of each share of Cardinal Common Stock such stockholder holds as determined pursuant to the Merger Agreement, in each case, without any interest thereon. Subject to all applicable laws of escheat, such amounts shall be paid to such former shareholder of Cardinal, without interest, upon proper surrender of his, her or its Certificates or delivery of an affidavit of loss as described in Section 7.e.

c. Rounding of Cash in Lieu of Fractional Shares. All dollar amounts payable to any shareholder as a result of the payment of cash in lieu of fractional shares pursuant to Section 6.b will be rounded to the nearest whole cent (with one-half cent being rounded upward), based on the aggregate amount payable for all shares registered in such shareholder’s name. No interest will be paid or accrued on any cash payable in lieu of fractional shares or any unpaid dividends and distributions, if any, payable to holders of Certificates.

d. Automatic Conversion of Cardinal Certificates and Cardinal Book-Entry Shares. Following the Effective Time, Cardinal Certificates and Cardinal Book-Entry Shares that formerly represented shares of Cardinal Common Stock that are to be converted into the United Common Stock shall be deemed for all purposes to represent the number of whole shares of United Common Stock into which they have been converted, except that until exchanged in accordance with the provisions of this Section 7, the holders of such shares shall not be entitled to receive dividends or other distributions or payments in respect of United Common Stock.

A-5

e. Lost Cardinal Certificates; Failure to Surrender Cardinal Certificates. If any Certificates shall have been lost, stolen or destroyed, upon the making of an affidavit of that fact by the person claiming such Cardinal Certificate to be lost, stolen or destroyed and, if required by United, the posting by such person of a bond, in such reasonable amount as United may direct, as indemnity against any claim that may be made against it with respect to such Cardinal Certificate, the Exchange Agent will issue, in exchange for such lost, stolen or destroyed Cardinal Certificate, the Merger Consideration to be paid in respect of the shares of Cardinal Common Stock represented by such Cardinal Certificate.

8. Amendment. Subject to the terms of the Merger Agreement, this Plan of Merger may be amended by the Managers of UBV and the Board of Directors Cardinal at any time prior to the Effective Time; provided, however, that any amendment made subsequent to the approval of this Plan of Merger by the sole member of UBV, and the shareholders of United and Cardinal shall not:

a. alter or change the amount or kind of shares or other securities, eligible interests, obligations, rights to acquire shares, other securities or eligible interests, cash or other property or rights to be received under this Plan of Merger by the Cardinal shareholders;

b. alter or change any of the other terms or conditions of this Plan of Merger if the change would adversely Cardinal shareholders in any material respect; or

c. alter or change any term of the articles of incorporation of Cardinal, as amended, or the articles of organization of UBV, as amended.

9. Abandonment. At any time prior to the Effective Time, the Merger may be abandoned, subject to the terms of the Merger Agreement, without further shareholder action in the manner determined by the Boards of Directors of United and Cardinal and the Managers of UBV. Written notice of such abandonment shall be filed with the SCC prior to the Effective Time.

United Bankshares, Inc. and Cardinal Financial Corporation

Announce Merger Agreement

WASHINGTON, D.C. and CHARLESTON, WV — United Bankshares, Inc. (“United”) (NASDAQ: UBSI) Chairman and Chief Executive Officer, Richard M. Adams, announced the signing of a definitive merger agreement with Cardinal Financial Corporation (“Cardinal”) (NASDAQ: CFNL), a publicly traded financial services holding company headquartered in Tysons Corner, Virginia. This will mark the 31^st acquisition of the current administration and the tenth acquisition for United in the D.C. Metro region, one of the most attractive financial markets in the country.

Cardinal, with $4.2 billion in assets, provides banking services through its subsidiary bank, Cardinal Bank, which has a network of 30 branches throughout Virginia, Maryland and Washington, D.C. In addition, Cardinal operates George Mason Mortgage, LLC, a residential mortgage lending subsidiary, and Cardinal Wealth Services, Inc., a wealth management services subsidiary. Upon completion of the merger, United’s assets will grow to approximately $20 billion with a projected market capitalization of approximately $3.9 billion based on United’s closing price on August 16, 2016. Based upon this projected market capitalization, United would be the 32^nd largest banking company in the country.

Cardinal Bank will merge into United Bank, United’s Virginia chartered bank, the largest community bank headquartered in the D.C. Metro region. Upon completion of the merger, United Bank will have assets of approximately $14.4 billion and will continue to have the #1 deposit market share among community banks in the Washington, D.C. Metropolitan Statistical Area (MSA).

United will acquire 100% of the outstanding shares of Cardinal in exchange for common shares of United. The exchange ratio will be fixed at 0.71 of United’s shares for each share of Cardinal. The aggregate consideration of the transaction is approximately $912 million based on Cardinal’s common shares outstanding of 32.5 million and options outstanding of 1.02 million. The announced price represents 2.24 times Cardinal’s tangible book value at June 30, 2016.

The transaction was unanimously approved by United’s and Cardinal’s Boards of Directors and is expected to close mid-2017, pending regulatory approval and United and Cardinal shareholder approval.

Adams stated, “Cardinal is one of the most successful community banks in the country and has a significant presence in one of the best markets in the USA. This merger aligns perfectly with our long-standing commitment to growth in the D.C. Metro area. Both companies have strong ties to the local community, and share the goal of building meaningful relationships with the individuals, businesses, and organizations that contribute to its prosperity. By uniting, we reinforce our position as the largest locally headquartered community bank.”

Bernard H. Clineburg, Executive Chairman of Cardinal stated, “We are pleased Cardinal found a like-minded partner to further our growth in Northern Virginia, the District of Columbia, and Maryland. United brings to the table the capacity to meet the sophisticated needs of our customers, while at the same time staying true to our commitment to the communities we serve. In addition, the transaction will add tremendous value for our shareholders.” It is expected that Mr. Clineburg will join United’s Board of Directors at the time of the merger.

United currently has $14.3 billion in assets and 129 full-service offices in Washington, D.C., Virginia, Maryland, Ohio, Pennsylvania, and West Virginia.

Keefe, Bruyette & Woods, Inc. served as financial advisor and Bowles Rice LLP provided legal counsel to United.

Sandler O’Neill & Partners, L.P. served as financial advisor and LeClairRyan, A Professional Corporation served as legal counsel to Cardinal.
