AGREEMENT AND PLAN OF MERGER

AGREEMENT AND PLAN OF MERGER, dated as of November 14, 2013 (this “Agreement”), by and between United Financial Bancorp, Inc., a Maryland corporation (“United”), and Rockville Financial, Inc., a Connecticut corporation (“Rockville”). For the purposes of this Agreement, “Rockville” shall include Rockville’s pre second step mutual to stock conversion predecessor, also named Rockville, which conversion was completed on March 3, 2011.

W I T N E S S E T H:

WHEREAS, the Boards of Directors of Rockville and United have determined that it is in the best interests of their respective companies and their stockholders to consummate the strategic business combination transaction provided for herein, pursuant to which United will, subject to the terms and conditions set forth herein, merge with and into Rockville (the “Merger”), so that Rockville is the surviving corporation (hereinafter sometimes referred to in such capacity as the “Surviving Corporation”) in the Merger; and

WHEREAS, for Federal income tax purposes, it is intended that the Merger shall qualify as a “reorganization” within the meaning of Section 368(a) of the Internal Revenue Code of 1986, as amended (the “Code”), and this Agreement is intended to be and is adopted as a plan of reorganization for purposes of Sections 354 and 361 of the Code; and

WHEREAS, the parties desire to make certain representations, warranties and agreements in connection with the Merger and also to prescribe certain conditions to the Merger.

NOW, THEREFORE, in consideration of the mutual covenants, representations, warranties and agreements contained herein, and intending to be legally bound hereby, the parties agree as follows:

ARTICLE I

THE MERGER

1.1 The Merger. Subject to the terms and conditions of this Agreement, in accordance with the Maryland General Corporation Law (the “MGCL”) and the Connecticut Business Corporation Act (the “CBCA”), at the Effective Time, United shall merge with and into Rockville. Rockville shall be the Surviving Corporation in the Merger, and shall continue its corporate existence under the laws of the State of Connecticut. Upon consummation of the Merger, the separate corporate existence of United shall terminate.

1.2 Effective Time. The Merger shall become effective as set forth in the articles of merger to be filed with the State Department of Assessments and Taxation of the State of Maryland (the “Maryland Department”) and the certificate of merger to be filed with the Secretary of State of the State of Connecticut (the “Connecticut Secretary”), respectively, on the Closing Date (collectively, the “Certificates of Merger”). The term “Effective Time” shall be the date and time when the Merger becomes effective, as set forth in the Certificates of Merger.

1.3 Effects of the Merger. At and after the Effective Time, the Merger shall have the effects set forth in the applicable provisions of the MGCL and CBCA.

1.4 Conversion of United Common Stock. At the Effective Time, by virtue of the Merger and without any action on the part of Rockville, United or the holder of any of the following securities:

(a) Subject to Section 2.2(e), each share of the common stock, par value $0.01 per share, of United issued and outstanding immediately prior to the Effective Time (the “United Common Stock”), except for shares of United Common Stock owned by United as treasury stock or owned by United or Rockville (in each case other than in a fiduciary or agency capacity or as a result of debts previously contracted), shall be converted into the right to receive 1.3472 shares (the “Exchange Ratio”) of the common stock, no par value per share, of Rockville (the “Rockville Common Stock”); it being understood that upon the Effective Time, pursuant to Section 1.5, the Rockville Common Stock, including the shares issued to former holders of United Common Stock, shall be the common stock of the Surviving Corporation.

(b) All of the shares of United Common Stock converted into the right to receive Rockville Common Stock pursuant to this Article I shall no longer be outstanding and shall automatically be cancelled and shall cease to exist as of the Effective Time, and each certificate (each, a “Certificate,” it being understood that any reference herein to “Certificate” shall be deemed to include reference to book-entry account statements relating to the ownership of shares of United Common Stock) previously representing any such shares of United Common Stock shall thereafter represent only the right to receive (i) a certificate representing the number of whole shares of Rockville Common Stock which such shares of United Common Stock have been converted into the right to receive, (ii) cash in lieu of fractional shares which the shares of United Common Stock represented by such Certificate have been converted into the right to receive pursuant to this Section 1.4 and Section 2.2(e), without any interest thereon, and (iii) any dividends or distributions which the holder thereof has the right to receive pursuant to Section 2.2. Certificates previously representing shares of United Common Stock shall be exchanged for certificates representing whole shares of Rockville Common Stock (together with any dividends or distributions with respect thereto and cash in lieu of fractional shares issued in consideration therefor) upon the surrender of such Certificates in accordance with Section 2.2, without any interest thereon. If, prior to the Effective Time, the outstanding shares of Rockville Common Stock or United Common Stock shall have been increased, decreased, changed into or exchanged for a different number or kind of shares or securities as a result of a reorganization, recapitalization, reclassification, stock dividend, stock split, reverse stock split, or other similar change in capitalization, or there shall be any extraordinary dividend or distribution, an appropriate and proportionate adjustment shall be made to the Exchange Ratio.

(c) Notwithstanding anything in this Agreement to the contrary, at the Effective Time, all shares of United Common Stock that are owned by United or Rockville (in each case other than in a fiduciary or agency capacity or as a result of debts previously contracted) shall be cancelled and shall cease to exist and no stock of Rockville or other consideration shall be delivered in exchange therefor.

1.5 Rockville Common Stock. At and after the Effective Time, each share of Rockville Common Stock issued and outstanding immediately prior to the Effective Time shall remain an issued and outstanding share of common stock of the Surviving Corporation and shall not be affected by the Merger.

1.6 United Stock Options; United Restricted Stock Awards.

(a) At the Effective Time, each option granted by United to purchase shares of United Common Stock under a United Stock Plan (as defined below), whether vested or unvested, that is outstanding and unexercised immediately prior to the Effective Time (a “United Stock Option”) shall cease to represent a right to acquire shares of United Common Stock and shall be converted automatically into an option to purchase shares of Rockville Common Stock for a number of shares and at an exercise price determined as provided below, with such converted option to continue to be subject to the same terms and conditions as were applicable to the United Stock Option under the United Stock Plan and the applicable award agreement thereunder (but taking into account any acceleration or vesting thereof provided for in the United Stock Plan, or in the related award agreement, by reason of the consummation of the transactions contemplated hereby):

(i) The number of shares of Rockville Common Stock to be subject to the new option shall be equal to the product of the number of shares of United Common Stock subject to the United Stock Option and the Exchange Ratio; provided, that any fractional shares of Rockville Common Stock resulting from such multiplication shall be rounded down to the nearest whole share; and

(ii) The exercise price per share of Rockville Common Stock under the new option shall be equal to the exercise price per share of United Common Stock subject to the United Stock Option divided by the Exchange Ratio; provided, that such exercise price shall be rounded up to the nearest whole cent.

For purposes of this Agreement, “United Stock Plans” mean the United Financial Bancorp, Inc. 2006 Stock-Based Incentive Plan, the United Financial Bancorp, Inc. 2008 Equity Incentive Plan, the CNB Financial Corp. 2008 Equity Incentive Plan and the CNB Amended and Restated Stock Option Plan.

(b) At the Effective Time, all unvested United Stock Options shall fully vest.

(c) At the Effective Time, the restrictions on each United Restricted Stock Award shall automatically lapse and shall be treated as issued and outstanding shares of United Common Stock for the purposes of this Agreement, including but not limited to, the provisions of Section 1.4. For purposes of this Agreement, a “United Restricted Stock Award” is an award in respect of a share of United Common Stock subject to vesting, repurchase or other lapse restrictions granted under a United Stock Plan which is outstanding immediately prior to the Effective Time.

(d) At or prior to the Effective Time, United, the Board of Directors of United and its Compensation Committee, as applicable, shall adopt any resolutions and take any actions that are necessary to effectuate the provisions of this Section 1.6.

(e) At or prior to the Effective Time, Rockville, the Board of Directors of Rockville and its Compensation Committee, as applicable, shall adopt any resolutions and take any necessary actions to reserve for future issuance a number of shares of Rockville Common Stock necessary to fulfill Rockville’s obligations under this Section 1.6. Promptly after the Effective Time, Rockville shall prepare and file with the Securities and Exchange Commission (the “SEC”) a registration statement on Form S-8 (or other appropriate form) registering such shares of Rockville Common Stock.

1.7 Certificate of Incorporation of Surviving Corporation. At the Effective Time, (a) Section 1 of the Certificate of Incorporation of Rockville (the “Rockville Certificate”) shall be amended to change the name of Rockville from “Rockville Financial, Inc.” to “United Financial Bancorp, Inc.” and (b) subject to the approval of the Certificate of Amendment set forth in Exhibit A hereto (the “Certificate Amendment”) by the holders of Rockville Common Stock, such amended Rockville Certificate shall be further amended as set forth in the Certificate Amendment, and such Rockville Certificate as so amended shall be the Certificate of Incorporation of the Surviving Corporation until thereafter amended in accordance with applicable law.

1.8 Bylaws of Surviving Corporation. At the Effective Time, the Bylaws of Rockville, as in effect immediately prior to the Effective Time, as amended in the form as provided in Exhibit B (the “Bylaw Amendment”), shall be the Bylaws of the Surviving Corporation until thereafter amended in accordance with applicable law.

1.9 Tax Consequences. It is intended that the Merger shall qualify as a “reorganization” within the meaning of Section 368(a) of the Code, and that this Agreement is intended to be and is adopted as a “plan of reorganization” for the purposes of Sections 354 and 361 of the Code.

1.10 Bank Merger. Immediately following the Merger, United Bank, a federal savings bank and a wholly-owned Subsidiary of United (“United Bank”), will merge (the “Bank Merger”) with and into Rockville Bank, a state chartered stock savings bank and a wholly-owned Subsidiary of Rockville (“Rockville Bank”). Rockville Bank shall be the surviving entity in the Bank Merger and, following the Bank Merger, the separate corporate existence of United Bank shall cease. In connection with the Bank Merger, Rockville Bank shall change its name to “United Bank.” The parties agree that the Bank Merger shall become effective immediately after the Effective Time. On the date of this Agreement, Rockville Bank and United Bank entered into the agreement and plan of merger attached hereto as Exhibit C (the “Bank Merger Agreement”). United shall cause United Bank, and Rockville shall cause Rockville Bank, to execute such certificates of merger and other documents and certificates as are necessary to make the Bank Merger effective (“Bank Merger Certificates”) immediately following the Effective Time.

1.11 Headquarters of Surviving Corporation; Name. From and after the Effective Time, (i) the location of the headquarters and principal executive offices of the Surviving Corporation shall be ▇▇ ▇▇▇▇▇▇▇▇▇▇▇ ▇▇▇▇▇▇▇▇▇, ▇▇▇▇▇▇▇▇▇▇▇, Connecticut, and the Surviving Corporation shall maintain executive offices in Glastonbury, Connecticut and West Springfield, Massachusetts, and (ii) the name of the Surviving Corporation shall be “United Financial Bancorp, Inc.”

ARTICLE II

EXCHANGE OF SHARES

2.1 Rockville to Make Shares Available. At or prior to the Effective Time, Rockville shall deposit, or shall cause to be deposited, with a stock registrar and transfer company designated by Rockville and reasonably acceptable to United (the “Exchange Agent”), for the benefit of the holders of Certificates, for exchange in accordance with this Article II, certificates or, at Rockville’s option, evidence of shares in book entry form (collectively, referred to herein as “certificates”), representing the shares of Rockville Common Stock, and cash in lieu of any fractional shares (such cash and certificates for shares of Rockville Common Stock, together with any dividends or distributions with respect thereto, being hereinafter referred to as the “Exchange Fund”), to be issued pursuant to Section 1.4 and paid pursuant to Section 2.2(a) in exchange for outstanding shares of United Common Stock.

2.2 Exchange of Shares.

(a) As promptly as practicable after the Effective Time, but in no event later than five Business Days thereafter, Rockville shall cause the Exchange Agent to mail to each holder of record of one or more Certificates representing shares of United Common Stock immediately prior to the Effective Time that have been converted at the Effective Time into the right to receive Rockville Common Stock pursuant to Article I, a letter of transmittal (which shall specify that delivery shall be effected, and risk of loss and title to the Certificates shall pass, only upon proper delivery of the Certificates to the Exchange Agent) and instructions for use in effecting the surrender of the Certificates in exchange for certificates representing the number of whole shares of Rockville Common Stock and any cash in lieu of fractional shares which the shares of United Common Stock represented by such Certificate or 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 a Certificate or Certificates for exchange and cancellation to the Exchange Agent, together with such properly completed letter of transmittal, duly executed, the holder of such Certificate or Certificates shall be entitled to receive in exchange therefor, as applicable, (i) a certificate representing that number of whole shares of Rockville Common Stock to which such holder of United Common Stock shall have become entitled pursuant to the provisions of Article I and (ii) a check representing the amount of (A) any cash in lieu of fractional shares which such holder has the right to receive in respect of the Certificate or Certificates surrendered pursuant to the provisions of this Article II and (B) any dividends or distributions which the holder thereof has the right to receive pursuant to Section 2.2, and the Certificate or Certificates so surrendered shall forthwith be cancelled. No interest will be paid or accrued on any cash in lieu of fractional shares payable

to holders of Certificates. Until surrendered as contemplated by this Section 2.2, each Certificate shall be deemed at any time after the Effective Time to represent only the right to receive, upon surrender, the number of whole shares of Rockville Common Stock which the shares of United Common Stock represented by such 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 Rockville Common Stock shall be paid to the holder of any unsurrendered Certificate until the holder thereof shall surrender such Certificate in accordance with this Article II. After the surrender of a 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 Rockville Common Stock which the shares of United Common Stock represented by such Certificate have been converted into the right to receive.

(c) If any certificate representing shares of Rockville Common Stock is to be issued in a name other than that in which the Certificate or Certificates surrendered in exchange therefor is or are registered, it shall be a condition of the issuance thereof that the Certificate or Certificates so surrendered shall be properly endorsed (or accompanied by an appropriate instrument of transfer) and otherwise in proper form for transfer.

(d) After the Effective Time, there shall be no transfers on the stock transfer books of United of the shares of United Common Stock that were issued and outstanding immediately prior to the Effective Time. If, after the Effective Time, Certificates representing such shares are presented for transfer to the Exchange Agent, they shall be cancelled and exchanged for certificates representing shares of Rockville Common Stock as provided in this Article II.

(e) Notwithstanding anything to the contrary contained herein, no certificates or scrip representing fractional shares of Rockville Common Stock shall be issued upon the surrender for exchange of Certificates, no dividend or distribution with respect to Rockville 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 Rockville. In lieu of the issuance of any such fractional share, Rockville shall pay to each former stockholder of United 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 Rockville Common Stock on The NASDAQ Stock Market LLC (“NASDAQ”) as reported by The Wall Street Journal for the five (5) full trading days ending on the third day preceding the Closing Date by (ii) the fraction of a share (rounded to the nearest thousandth when expressed in decimal form) of Rockville Common Stock which such holder would otherwise be entitled to receive pursuant to Section 1.4.

(f) Any portion of the Exchange Fund that remains unclaimed by the stockholders of United for twelve (12) months after the Effective Time shall be paid to the Surviving Corporation. Any former stockholders of United who have not theretofore complied with this Article II shall thereafter look only to the Surviving Corporation for payment of the shares of Rockville Common Stock, cash in lieu of any fractional shares and any unpaid dividends and

distributions on the Rockville Common Stock deliverable in respect of each former share of United Common Stock such stockholder holds as determined pursuant to this Agreement, in each case, without any interest thereon. Notwithstanding the foregoing, none of Rockville, United, the Surviving Corporation, the Exchange Agent or any other person shall be liable to any former holder of shares of United Common Stock for any amount delivered in good faith to a public official pursuant to applicable abandoned property, escheat or similar laws.

(g) Rockville 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 Rockville Common Stock, cash dividends or distributions payable pursuant to this Section 2.2 or any other cash amounts otherwise payable pursuant to this Agreement to any holder of United Common Stock 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 Rockville 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 United Common Stock in respect of which the deduction and withholding was made by Rockville or the Exchange Agent, as the case may be.

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

ARTICLE III

REPRESENTATIONS AND WARRANTIES OF UNITED

Except (i) as disclosed in the disclosure schedule delivered by United to Rockville concurrently herewith (the “United Disclosure Schedule”); provided, that (a) no such item is required to be set forth as an exception to a representation or warranty if its absence would not result in the related representation or warranty being deemed untrue or incorrect, (b) the mere inclusion of an item in the United Disclosure Schedule as an exception to a representation or warranty shall not be deemed an admission by United that such item represents a material exception or fact, event or circumstance or that such item is reasonably likely to result in a Material Adverse Effect and (c) any disclosures made with respect to a section of Article III shall be deemed to qualify (1) any other section of Article III specifically referenced or cross-referenced and (2) other sections of Article III to the extent it is reasonably apparent on its face (notwithstanding the absence of a specific cross reference) from a reading of the disclosure that such disclosure applies to such other sections or (ii) as disclosed in any United Reports filed by United since December 31, 2010, and prior to the date hereof (but disregarding risk factor disclosures contained under the heading “Risk Factors,” or disclosures of risks set forth in any “forward-looking statements” disclaimer or any other statements that are similarly non-specific

or cautionary, predictive or forward-looking in nature), United hereby represents and warrants to Rockville as follows:

3.1 Corporate Organization.

(a) United is a corporation duly organized, validly existing and in good standing under the laws of the State of Maryland and is a unitary savings and loan holding company duly registered under the Home Owners’ Loan Act of 1933, as amended (the “HOLA Act”). United has the corporate power and authority to own or lease all of its properties and assets and to carry on its business as it is now being conducted. United is duly licensed or qualified to do business in each jurisdiction in which the nature of the business conducted by it or the character or location of the properties and assets owned or leased by it makes such licensing or qualification necessary, except where the failure to be so licensed or qualified would not, either individually or in the aggregate, reasonably be expected to have a Material Adverse Effect on United. As used in this Agreement, the term “Material Adverse Effect” means, with respect to Rockville, United or the Surviving Corporation, as the case may be, any event, circumstance, development, change or effect that, individually or in the aggregate that (i) is or is reasonably likely to be, material and adverse to the business, properties, results of operations or financial condition of such party and its Subsidiaries taken as a whole (provided, however, that, with respect to this clause (i), Material Adverse Effect shall not be deemed to include the impact of (A) changes, after the date hereof, in U.S. generally accepted accounting principles (“GAAP”) or applicable regulatory accounting requirements, (B) changes, after the date hereof, in laws, rules or regulations of general applicability to companies in the industries in which such party and its Subsidiaries operate, or interpretations thereof by courts or Governmental Entities, (C) changes, after the date hereof, in global, national or regional political conditions (including the outbreak of war or acts of terrorism) or in economic or market (including equity, credit and debt markets, as well as changes in interest rates) conditions affecting the financial services industry generally and not specifically relating to such party or its Subsidiaries, (D) public disclosure of the transactions contemplated hereby or actions expressly required by this Agreement or that are taken with the prior written consent of the other party in contemplation of the transactions contemplated hereby, or (E) a decline in the trading price of a party’s common stock or the failure, in and of itself, to meet earnings projections, but not, in either case, including the underlying causes thereof; except, with respect to subclauses (A), (B), or (C), to the extent that the effects of such change are materially disproportionately adverse to the business, properties, assets, liabilities, results of operations or financial condition of such party and its Subsidiaries, taken as a whole, as compared to other companies in the industry in which such party and its Subsidiaries operate) or (ii) prevents or materially impairs, or would be reasonably likely to prevent or materially impair, the ability of Rockville or United to timely consummate the Merger on the terms set forth herein, or to perform its agreements or covenants hereunder. As used in this Agreement, the word “Subsidiary” when used with respect to any party, means any corporation, partnership, limited liability company, bank or other organization, whether incorporated or unincorporated, which is consolidated with such party for financial reporting purposes.

(b) Each Subsidiary of United (a “United 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) in which the nature of the business conducted by it or the character or location of the properties and assets owned or leased by it makes such licensing or qualification necessary, except where the failure to be so licensed or qualified would reasonably be expected to have a Material Adverse Effect on United and (iii) has all requisite corporate power and authority to own or lease its properties and assets and to carry on its business as now conducted. There are no restrictions on the ability of any Subsidiary of United to pay dividends or distributions except, in the case of a Subsidiary that is a regulated entity, for restrictions on dividends or distributions generally applicable to all such regulated entities. The deposit accounts of each Subsidiary of United that is an insured depository institution are insured by the Federal Deposit Insurance Corporation (the “FDIC”) through the Deposit Insurance Fund to the fullest extent permitted by law, all premiums and assessments required to be paid in connection therewith have been paid when due, and no proceedings for the termination of such insurance are pending or threatened.

(b) Except as would not reasonably be expected to have, either individually or in the aggregate, a Material Adverse Effect on United, neither United nor any of its Subsidiaries has any liability of any nature whatsoever (whether absolute, accrued, contingent or otherwise and whether due or to become due), except for those liabilities that are reflected or reserved against on the consolidated statement of condition of United included in its Quarterly Report on Form 10-Q for the quarter ended September 30, 2013 (including any notes thereto) and for liabilities incurred in the ordinary course of business consistent with past practice since September 30, 2013, or in connection with this Agreement and the transactions contemplated hereby.

(c) Subject to applicable law relating to the exchange of information, Rockville and United shall, upon request, furnish each other with all information concerning themselves, their Subsidiaries, directors, officers and stockholders and such other matters as may be reasonably necessary or advisable in connection with the Joint Proxy Statement, the S-4 or any other statement, filing, notice or application made by or on behalf of Rockville, United or any of their respective Subsidiaries to any Governmental Entity in connection with the Merger, the Bank Merger and the other transactions contemplated by this Agreement.

(d) Rockville and United shall promptly advise each other upon receiving any communication from any Governmental Entity whose consent or approval is required for consummation of the transactions contemplated by this Agreement that causes such party to believe that there is a reasonable likelihood that any Requisite Regulatory Approval will not be obtained or that the receipt of any such approval will be materially delayed.

(e) In furtherance and not in limitation of the foregoing, each of United and Rockville shall use its reasonable best efforts to, and cause its Subsidiaries to use reasonable best efforts to, (i) avoid the entry of, or to have vacated, lifted, reversed or overturned any decree, judgment, injunction or other order, whether temporary, preliminary or permanent, that would restrain, prevent or delay the Closing, and (ii) avoid or eliminate each and every impediment under any applicable law, rule or regulation so as to enable the Closing to occur as soon as possible; provided, however, that nothing contained in this Agreement shall require United or Rockville to take any actions specified in this Section 6.1(e) that would reasonably be expected to constitute or result in a Materially Burdensome Regulatory Condition.

6.2 Access to Information.

(a) Upon reasonable notice and subject to applicable laws, each of Rockville and United, in preparing for the Merger and the other matters contemplated by this Agreement, shall, and shall cause each of their respective Subsidiaries to, afford to the Representatives of the other party, access, during the period prior to the Effective Time, to all its properties, books, contracts,

commitments, personnel, information technology systems, and records, which such access shall occur during normal business hours and shall be conducted in a manner so as not to interfere unreasonably with the conduct of the business of United or Rockville or its respective Subsidiaries and each shall cooperate with the other party in preparing to execute after the Effective Time conversion or consolidation of systems and business operations generally, and, during such period, each of Rockville and United shall, and shall cause its respective Subsidiaries to, make available to the other party (i) a copy of each report, schedule, registration statement and other document filed or received by it during such period pursuant to the requirements of federal securities laws or federal or state banking laws (other than reports or documents which Rockville or United, as the case may be, is not permitted to disclose under applicable law), and (ii) all other information concerning its business, properties and personnel as such party may reasonably request. Neither Rockville nor United nor any of their respective Subsidiaries shall be required to provide access to or to disclose information where such access or disclosure would violate or prejudice the rights of Rockville’s or United’s, as the case may be, customers, jeopardize the attorney-client privilege of the institution in possession or control of such information (after giving due consideration to the existence of any common interest, joint defense or similar agreement between the parties) or contravene any law, rule, regulation, order, judgment, decree, fiduciary duty or binding agreement entered into prior to the date of this Agreement. The parties hereto will make appropriate substitute disclosure arrangements under circumstances in which the restrictions of the preceding sentence apply.

(b) Each of Rockville and United shall hold all information furnished by or on behalf of the other party or any of such party’s Subsidiaries or Representatives pursuant to Section 6.2(a) in confidence to the extent required by, and in accordance with, the provisions of the confidentiality agreement, dated October 16, 2013, between Rockville and United (the “Confidentiality Agreement”).

(c) No investigation by either of the parties or their respective Representatives shall affect or be deemed to modify or waive the representations and warranties of the other set forth herein. Nothing contained in this Agreement shall give either party, directly or indirectly, the right to control or direct the operations of the other party prior to the Effective Time. Prior to the Effective Time, each party shall exercise, consistent with the terms and conditions of this Agreement, complete control and supervision over its and its Subsidiaries’ respective operations.

6.3 Stockholders’ Approvals. Each of Rockville and United shall call a meeting of its stockholders (the “Rockville Meeting” and the “United Meeting,” respectively) to be held as soon as reasonably practicable after the S-4 is declared effective for the purpose of obtaining (i) the Requisite United Vote and the Requisite Rockville Vote required in connection with this Agreement and the Merger, (ii) in the case of the Rockville Meeting, the requisite approval of the Certificate Amendment by the holders of Rockville Common Stock and (iii) the requisite approval, if so desired and mutually agreed, upon other matters of the type customarily brought before an annual or special meeting of stockholders to approve a merger agreement, and each shall use its reasonable best efforts to cause such meetings to occur as soon as reasonably practicable and on the same date. The Board of Directors of each of Rockville and United shall use its reasonable best efforts to obtain from the stockholders of Rockville and United, as the case may be, the Requisite Rockville Vote and the requisite approval of the Certificate

Amendment by the holders of Rockville Common Stock, in the case of Rockville, and the Requisite United Vote, in the case of United, including by communicating to its respective shareholders its recommendation (and including such recommendation in the Joint Proxy Statement) that they approve this Agreement and the transactions contemplated hereby. However, if the Board of Directors of United or Rockville, after receiving the advice of its outside counsel and, with respect to financial matters, its financial advisor, determines in good faith that it would more likely than not result in a violation of its fiduciary duties under applicable law to continue to recommend this Agreement, then in submitting this Agreement to its stockholders, such Board of Directors may 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 the 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 the Board of Directors may not take any actions under this sentence unless (i) it gives the other party at least three 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 and the identity of the third party in any such Acquisition Proposal, or any amendment or modification thereof, or describe in reasonable detail such other event or circumstances) and (ii) at the end of such notice period, the Board of Directors 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 advisor, determines in good faith that it would nevertheless more likely than not result in a violation of its fiduciary duties under applicable law to continue to recommend this Agreement. 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. Rockville or United shall adjourn or postpone the Rockville Meeting or the United Meeting, as the case may be, if, as of the time for which such meeting is originally scheduled there are insufficient shares of Rockville Common Stock or United 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, subject to approval of a proposal to do so by the stockholders, if on the date of such meeting United or Rockville, as applicable, has not received proxies representing a sufficient number of shares necessary to obtain the Requisite United Vote or the Requisite Rockville Vote. Notwithstanding anything to the contrary herein, unless this Agreement has been terminated in accordance with its terms, each of the Rockville Meeting and United Meeting shall be convened and this Agreement shall be submitted to the stockholders of each of Rockville and United at the Rockville Meeting and the United Meeting, respectively, for the purpose of voting on the approval of this Agreement and the other matters contemplated hereby, and nothing contained herein shall be deemed to relieve either Rockville or United of such obligation.

6.4 Legal Conditions to Merger. Subject in all respects to Section 6.1 of this Agreement, each of Rockville and United 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 Merger 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 United or Rockville or any of their respective Subsidiaries in connection with the Merger, the Bank Merger and the other transactions contemplated by this Agreement.

6.5 Stock Exchange Listing. Prior to the Effective Time, Rockville shall file with NASDAQ a Listing of Additional Shares Notification Form with respect to the shares of Rockville Common Stock to be issued in the Merger.

6.6 Employee Benefit Plans.

(a) From and after the Effective Time, unless otherwise mutually determined, the Rockville Benefit Plans in effect as of the date of this Agreement (other than such benefit plans as may be mutually agreed) shall remain in effect with respect to employees of United and Rockville (and their respective Subsidiaries), respectively, covered by such plans at the Effective Time who continue to be employed by the Surviving Corporation or its Subsidiaries after the Effective Time until such time as the Surviving Corporation shall, subject to applicable law and the terms of such plans, modify any existing plans or adopt new benefit plans with respect to employees of the Surviving Corporation and its Subsidiaries (the “New Benefit Plans”). Employees of United who participate in the Rockville Benefit Plans shall receive credit for service with United for purposes of eligibility and vesting under the Rockville Benefit Plans. Prior to the Closing Date, United and Rockville shall cooperate in reviewing, evaluating and analyzing the Rockville Benefit Plans with a view towards developing appropriate New Benefit Plans for the employees covered thereby, as and if necessary. It is the intention of United and Rockville, to the extent permitted by applicable law, to develop any New Benefit Plans (including amending existing plans), as soon as reasonably practicable after the Effective Time, which, among other things, (i) treat similarly situated employees on a substantially equivalent basis, taking into account all relevant factors, including duties, geographic location, tenure, qualifications and abilities, and (ii) do not discriminate between employees who were covered by Rockville Benefit Plans, on the one hand, and those covered by United Benefit Plans on the other, at the Effective Time.

(b) With respect to any New Benefit Plans in which any employees of Rockville or United (or their Subsidiaries) prior to the Effective Time first become eligible to participate on or after the Effective Time (or with respect to participation of any United employee in a Rockville Benefit Plan prior to the implementation of the New Benefit Plans), and in which such employees did not participate prior to the Effective Time, the Surviving Corporation shall: (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 Rockville Benefit Plan or New Benefit Plans in which such employees first become eligible to participate after the Effective Time, except to the extent such pre-existing conditions, exclusions or waiting periods would apply under the analogous Rockville Benefit Plan or United Benefit Plan, as the case may be, (ii) provide each such employee and their eligible dependents with credit for any co-payments and deductibles paid prior to the Effective Time under a Rockville

Benefit Plan or United Benefit Plan (to the same extent that such credit was given under the analogous United or Rockville Benefit Plan prior to the Effective Time) in satisfying any applicable deductible or out-of-pocket requirements under any Rockville Benefit Plan or New Benefit Plans in which such employees first become eligible to participate after the Effective Time, and (iii) recognize all service of such employees with United and Rockville, and their respective Subsidiaries, for all purposes in any New Benefit Plan in which such employees first become eligible to participate after the Effective Time to the same extent that such service was taken into account under the analogous United or Rockville Benefit Plan prior to the Effective Time; provided, that the foregoing service recognition shall not apply (A) to the extent it would result in duplication of benefits for the same period of services, (B) for purposes of any defined benefit pension plan or benefit plan that provides retiree welfare benefits, or (C) to any benefit plan that is a frozen plan or provides grandfathered benefits.

(c) The Surviving Corporation agrees to honor in accordance with their terms all benefits vested as of the date hereof under the Rockville Benefit Plans or the United Benefit Plans and each employment agreement and change in control agreement listed on Section 3.11(a) of the United Disclosure Schedule and Section 4.11(a) of the Rockville Disclosure Schedule. Each of Rockville and United agrees that, for purposes of each United Stock Plan and each employment agreement and change in control agreement listed on Section 3.11(l) of the United Disclosure Schedule, the transactions contemplated by this Agreement constitute a “change in control,” “change of control” or term of similar meaning.

(d) Nothing in this Agreement shall confer upon any employee, officer, director or consultant of Rockville or United or any of their Subsidiaries or affiliates any right to continue in the employ or service of the Surviving Corporation, United, Rockville or any Subsidiary or affiliate thereof, or shall interfere with or restrict in any way the rights of the Surviving Corporation, United, Rockville or any Subsidiary or affiliate thereof to discharge or terminate the services of any employee, officer, director or consultant of Rockville or United 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 United Benefit Plan, Rockville Benefit Plan, New Benefit Plan or any other benefit or employment plan, program, agreement or arrangement, or (ii) alter or limit the ability of the Surviving Corporation or any of its Subsidiaries or affiliates to amend, modify or terminate any particular United Benefit Plan, Rockville Benefit Plan, New Benefit Plan or any other benefit or employment plan, program, agreement or arrangement after the Effective Time. Without limiting the generality of the final sentence of Section 9.10, nothing in this Agreement, express or implied, is intended to or shall confer upon any person, including without limitation any current or former employee, officer, director or consultant of Rockville or United or any of their Subsidiaries or affiliates, any right, benefit or remedy of any nature whatsoever under or by reason of this Agreement.

(e) Unless otherwise agreed to by Rockville and United, for a period of one year following the Effective Time, the Surviving Corporation shall provide or cause to be provided each individual who is an employee of United or any of its Subsidiaries at the Effective Time, while such individual is employed by the Surviving Corporation or any of its Subsidiaries, with compensation and benefits that are substantially comparable in the aggregate to the

compensation and benefits provided to similarly situated employees of Rockville and its Subsidiaries.

(f) Rockville and United agree that each full-time Rockville or United employee who is involuntarily terminated (other than for “Cause”) or voluntarily resigns after being notified that, as a condition to employment, such employee’s base salary will be materially decreased at the Effective Time or within one year of the Effective Time and who is not covered by a separate severance, change in control or employment agreement shall receive a severance payment equal to two weeks of base pay (at the rate in effect on the termination date) for each year of service at Rockville or United, with a minimum of 12 weeks of base pay and a maximum equal to 52 weeks of base pay. For purposes of calculating the number of years of service, fractional years of service shall be rounded up to the nearest full year. For purposes of calculating base pay, employees who are paid on an hourly basis shall be deemed to have a base pay equal to the employee’s average weekly compensation over the two months prior to the termination date. For these purposes, “Cause” shall mean termination due to the employee’s personal dishonesty, willful misconduct, any breach of fiduciary duty involving personal profit, intentional failure to perform stated duties, willful violation of any law, rule or regulation (other than minor traffic violations or similar offenses) or final cease-and-desist order.

(g) Simultaneous with the execution of this Agreement, Rockville shall enter into an Advisory Agreement with ▇▇▇▇▇▇▇ ▇. ▇▇▇▇▇▇▇ to be effective as of and subject to the occurrence of the Effective Time, which agreement shall contain a two-year non-compete covenant.

(h) Simultaneous with the execution of this Agreement, Rockville shall enter into a three-year employment agreement with each of ▇▇▇▇▇▇▇ ▇. ▇. ▇▇▇▇▇▇▇▇, ▇▇ and J. ▇▇▇▇▇▇▇ ▇▇▇▇▇▇▇▇ (collectively, the “Key Individuals”) to be effective as of and subject to the occurrence of the Effective Time, which agreement shall set forth the terms and conditions of such Key Individuals’ employment with the Surviving Corporation following the Effective Time and shall, if and when the Effective Time occurs, supersede and replace any prior employment, retention, change of control or other similar agreement between such Key Individual and Rockville or United, as the case may be.

6.7 Indemnification; Directors’ and Officers’ Insurance.

(a) From and after the Effective Time, each of Rockville and the Surviving Corporation shall indemnify and hold harmless each present and former director, officer or employee of United and its Subsidiaries and any person who becomes a director, officer or employee before the Effective Time (in each case, when acting in such capacity) (collectively, the “United Indemnified Parties”) against any costs or expenses (including reasonable attorneys’ fees), judgments, fines, losses, damages or liabilities incurred or amounts that are paid in settlement (which shall require the prior written consent of Rockville, which consent shall not be unreasonably withheld) 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 the fact that such person is or was a director, officer or employee of United or any of its Subsidiaries and pertaining to matters existing or occurring at or prior to the Effective Time, including the transactions contemplated

by this Agreement to the same extent as such persons are indemnified as of the date of this Agreement by United pursuant to the United Articles, United’s Bylaws, the governing or organizational documents of any Subsidiary of United, any indemnification agreements in existence as of the date hereof and to the fullest extent permitted by applicable law; and Rockville and the Surviving Corporation shall also advance expenses as incurred by such United Indemnified Party (including reasonable attorneys’ fees) to the same extent as such persons are entitled to advancement of expenses as of the date of this Agreement by United pursuant to the United Articles, United’s Bylaws, the governing or organizational documents of any Subsidiary of United, any indemnification agreements in existence as of the date hereof and to the fullest extent permitted by applicable law; provided, that the United Indemnified Party to whom expenses are advanced provides an undertaking to repay such advances if it is ultimately determined that such United Indemnified Party is not entitled to indemnification.

(b) For a period of six (6) years after the Effective Time, the Surviving Corporation shall cause to be maintained in effect the current policies of directors’ and officers’ liability insurance maintained by United (provided, that the Surviving Corporation may substitute therefor policies with a substantially comparable insurer of at least the same coverage and amounts containing terms and conditions which are no less advantageous to the insured) with respect to claims arising from facts or events which occurred at or before the Effective Time; provided, however, that the Surviving Corporation 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 United for such insurance (the “Premium Cap”), and if such premiums for such insurance would at any time exceed the Premium Cap, then the Surviving Corporation shall cause to be maintained policies of insurance which, in the Surviving Corporation’s good faith determination, provide the maximum coverage available at an annual premium equal to the Premium Cap. In lieu of the foregoing, United, in consultation with, but only upon the consent of Rockville, may obtain at or prior to the Effective Time a six-year “tail” policy under United’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, on an annual basis, 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 United Indemnified Party and his or her heirs and Representatives. If the Surviving Corporation or any of its successors or assigns will consolidate with or merge into any other entity and not be the continuing or surviving entity of such consolidation or merger, transfer all or substantially all of its assets or deposits to any other entity or engage in any similar transaction, then in each case, the Surviving Corporation will cause proper provision to be made so that the successors and assigns of the Surviving Corporation will expressly assume the obligations set forth in this Section 6.7.

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, without limitation, any merger between a Subsidiary of Rockville, on the one hand, and a Subsidiary of United, on the other) or to vest the Surviving Corporation with full title to all properties, assets, rights, approvals, immunities and franchises of any of the parties to the Merger, the proper officers and directors of each party to this Agreement and their respective Subsidiaries shall, at

the Surviving Corporation’s sole expense, take all such necessary action as may be reasonably requested by Rockville.

6.9 Advice of Changes. Rockville and United shall each promptly advise the other party of any change or event (i) that has had or is reasonably likely to have a Material Adverse Effect on it or (ii) which it believes would or would be reasonably likely to cause or constitute a material breach of any of its representations, warranties or covenants contained herein that reasonably could be expected to give rise, individually or in the aggregate, to the failure of a condition in Article VII to be satisfied; 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.

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

6.11 Corporate Governance.

(a) Immediately prior to the execution and delivery of this Agreement, the Board of Directors of Rockville adopted a resolution, which may not be withdrawn unless this Agreement is terminated in accordance with its terms, providing for the Bylaw Amendment, effective as of the Effective Time. The provisions of the Bylaw Amendment shall be considered an agreement of the parties to this Agreement in all respects. In accordance with, and as provided in, the Bylaw Amendment, effective as of the Effective Time, (i) ▇▇▇▇▇▇ ▇. ▇▇▇▇▇▇▇, ▇▇. shall serve as Chairman of the Board of Directors of the Surviving Corporation and Rockville Bank, (ii) ▇▇▇▇▇▇▇ ▇. ▇▇▇▇▇▇▇, ▇▇. shall serve as Vice Chairman of the Board of Directors of the Surviving Corporation and Rockville Bank, (iii) ▇▇▇▇▇▇▇ ▇. ▇. ▇▇▇▇▇▇▇▇, ▇▇ shall serve as Chief Executive Officer of the Surviving Corporation and Rockville Bank and (iv) J. ▇▇▇▇▇▇▇ ▇▇▇▇▇▇▇▇ shall serve as President of the Surviving Corporation and Rockville Bank.

(b) In accordance with, and as provided in, the Bylaw Amendment, Rockville’s Board of Directors shall cause the number of directors that will constitute the full Board of Directors of the Surviving Corporation at the Effective Time to be twenty (20), in the event the holders of Rockville Common Stock approve the Certificate Amendment, or sixteen (16), in the event the holders of Rockville Common Stock do not approve the Certificate Amendment. Half of the members of the Board of Directors of the Surviving Corporation at the Effective Time shall be current Rockville directors designated by Rockville (the “Rockville Director Designees”), including the current Chief Executive Officer of Rockville, and half of the members of the Board of Directors of the Surviving Corporation at the Effective Time shall be

current United directors designated by United (other than the current President and Chief Executive Officer of United, who will be replaced by the current Executive Vice President and Chief Operating Officer of United) (the “United Director Designees”). The Surviving Corporation’s Board of Directors shall cause each of the Key Individuals (i) to be placed in the class of directors whose term shall expire at the Surviving Corporation’s first annual meeting of shareholders following the Closing Date (or special meeting in lieu thereof) and (ii) subject to satisfaction of the Surviving Corporation’s then-existing re-nomination policies and criteria applicable to incumbent directors, to be nominated for election to a full term at such annual meeting of shareholders (or special meeting in lieu thereof). In the event that any of the foregoing directors becomes unavailable to serve on the Board of Directors of the Surviving Corporation as of the Effective Time for any reason, a replacement designated by Rockville if the director was a Rockville director, or by United if the director was a United director, shall be appointed to the Surviving Corporation’s Board of Directors (or, if mutually agreeable to Rockville and United, the Board can be reduced in number provided the total membership on the Board consists of an equal number of directors from Rockville and United). Until the point in time immediately prior to the later of the Surviving Corporation’s third annual meeting of shareholders following the Closing Date or the 2017 annual meeting of shareholders (or special meeting in lieu thereof), each committee of the Board of Directors of the Surviving Corporation shall consist of an equal number of directors designated initially by Rockville and subsequent to the Closing Date by the Rockville Director Designees and an equal number of directors designated initially by United and subsequent to the Closing Date by the United Director Designees.

(c) On or prior to the Effective Time, Rockville (as the sole shareholder of Rockville Bank) shall cause the number of directors that will constitute the full Board of Directors of Rockville Bank at the Effective Time to be twenty (20). The full Board of Directors of Rockville Bank at the Effective Time shall be constituted in the same manner and with the same individuals as the Board of Directors of the Surviving Corporation and subject to the same requirements set forth in Section 6.11(b) of this Agreement and the Bylaw Amendment, except that in the event the Certificate Amendment is not approved by the holders of Rockville Common Stock, the Board of Directors of Rockville Bank at the Effective Time shall consist of the Rockville Director Designees, the current Rockville directors who are not Rockville Director Designees, the United Director Designees and the current United directors who are not United Director Designees, other than the current President and Chief Executive Officer of United.

6.12 Acquisition Proposals.

(a) Each party agrees that it will not, and will cause its Subsidiaries and its and their officers, directors, agents, advisors and representatives (collectively, “Representatives”) not to, directly or indirectly, (i) initiate, solicit, knowingly encourage or knowingly facilitate inquiries or proposals with respect to any Acquisition Proposal, (ii) engage or participate in any negotiations with any person (or Representative of such 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 (or Representative of such person) relating to, any Acquisition Proposal, (iv) approve or execute or enter into any letter of intent, agreement in principle, merger agreement, asset purchase or share exchange agreement, option agreement or other contract

related to any Acquisition Proposal or (v) propose or agree to do any of the foregoing; provided, that, prior to the applicable vote, in the event either 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 nonpublic information or data and participate in such negotiations or discussions to the extent that 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 advisor) 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, further, that, prior to providing any nonpublic information permitted to be provided pursuant to the foregoing proviso, such party shall have entered into a confidentiality agreement with such third party 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 United or Rockville, 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), 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) As used in this Agreement, “Acquisition Proposal” shall mean, other than the transactions contemplated by this Agreement, any offer, proposal or inquiry relating to, or any third party indication of interest in, (i) any acquisition or purchase, direct or indirect, of 25% or more of the consolidated assets of a party and its Subsidiaries or 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 more than 25% 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 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 more than 25% 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 more than 25% of the consolidated assets of the party.

(c) 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.

6.13 Public Announcements. United and Rockville agree that the press release announcing the execution and delivery of this Agreement shall be a joint press release of United

and Rockville. Thereafter, United and Rockville shall each use their reasonable best efforts (a) to develop a joint communications plan with respect to the transactions contemplated hereby, (b) to ensure that all press releases and other public statements with respect to the transactions contemplated hereby shall be consistent with such joint communications plan, and (c) except in respect of any announcement required by applicable law, or by obligations pursuant to any listing agreement with or rules of any securities exchange, to consult with each other before issuing any press release or, to the extent practical, otherwise making any public statement with respect to this Agreement or the transactions contemplated hereby.

6.14 Change of Method. United and Rockville shall be empowered, upon their mutual agreement, at any time prior to the Effective Time, to change the method or structure of effecting the combination of United and Rockville (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 Rockville Common Stock received by United stockholders in exchange for each share of United Common Stock, (ii) adversely affect the Tax treatment of United’s stockholders or Rockville’s stockholders pursuant to this Agreement, (iii) adversely affect the Tax treatment of United or Rockville 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 8.3.

6.15 Takeover Statutes. None of United, Rockville or their respective Boards of Directors shall take any action that would cause any Takeover Statute to become applicable to this Agreement, the Merger, or any of the other transactions contemplated hereby, and each shall take all necessary steps to exempt (or ensure the continued exemption of) the Merger 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 thereby 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.

6.16 Exemption from Liability Under Section 16(b). United and Rockville agree that, in order to most effectively compensate and retain United Insiders (as defined below), both prior to and after the Effective Time, it is desirable that United 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 United Common Stock into shares of Rockville Common Stock in the Merger and the conversion of United Stock Options and United Restricted Stock Awards pursuant to Section 1.6, and for that compensatory and retentive purposes agree to the provisions of this Section 6.16. Assuming United delivers to Rockville in a reasonably timely fashion prior to the Effective Time accurate information regarding those officers and directors of United subject to the reporting requirements of Section 16(a) of the Exchange Act (the “United Insiders”), the Board of Directors of Rockville and of United, 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 any dispositions of United Common Stock, United Restricted Stock Awards or United Stock Options by the United Insiders, and any acquisitions of Rockville Common Stock or Rockville Stock Options by any United Insiders who, immediately following the Merger, will be officers or directors of the Surviving Corporation 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.

6.17 Assumption by Rockville of Certain Obligations. At or before the Closing, Rockville shall deliver agreements or supplemental indentures as required and in a form reasonably satisfactory to United and the trustee named in such agreements and indentures, as of the Effective Time, to assume expressly the due and punctual performance and observance of each and every covenant, agreement and condition (insofar as such covenant, agreement or condition is to be performed and observed by the Surviving Corporation) of the indentures, trust agreements and guarantee agreements entered into by United, each as more specifically identified on Section 6.17 of the United Disclosure Schedule.

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 approval of this Agreement by the stockholders of Rockville or United:

(a) by mutual consent of Rockville and United in a written instrument, if the Board of Directors of each so determines by a vote of a majority of the members of its entire Board;

(b) by either Rockville or United if any Governmental Entity that must grant a Requisite Regulatory Approval has (i) denied approval of the Merger or the Bank Merger and such denial has become final and nonappealable or any Governmental Entity of competent jurisdiction shall have issued a final nonappealable order permanently enjoining or otherwise prohibiting or making illegal the consummation of the transactions contemplated by this Agreement or (ii) granted the Requisite Regulatory Approval but such Requisite Regulatory Approval contains or results in the imposition of a Materially Burdensome Condition, unless, in either case, the failure to obtain a Requisite Regulatory Approval or to obtain a Requisite Regulatory Approval without it containing or imposing a Materially Burdensome Condition shall be due to the failure of the party seeking to terminate this Agreement to perform or observe the covenants and agreements of such party set forth herein;

(c) by either Rockville or United if the Merger shall not have been consummated on or before September 14, 2014 (the “Termination Date”); provided that the right to terminate this Agreement under this Section 8.1(c) shall not be available to any party whose action or failure to act has been the cause of or resulted in the failure of the Closing to occur by such date;

(d) by either Rockville or United (provided, that the terminating party is not then in material breach of any representation, warranty, covenant or other agreement contained herein) if there shall have been a breach of any of the covenants or agreements or any of the representations or warranties set forth in this Agreement on the part of United, in the case of a termination by Rockville, or Rockville, in the case of a termination by United, which breach or failure to be true, either individually or in the aggregate with all other breaches by such party (or failures of such representations or warranties to be true), would constitute, if occurring or continuing on the Closing Date, the failure of a condition set forth in Section 7.2, in the case of a termination by Rockville, or 7.3, in the case of a termination by United, and which is not cured within 30 days following written notice to United, in the case of a termination by Rockville, or

Rockville, in the case of a termination by United, or by its nature or timing cannot be cured during such period (or such fewer days as remain prior to the Termination Date);

(e) by United, if the Board of Directors of Rockville shall have (i) failed to recommend in the Joint Proxy Statement that the stockholders of Rockville approve this Agreement or the Certificate Amendment, or withdrawn, modified or qualified such recommendation in a manner adverse to United, or resolved to do so, or failed to recommend against acceptance of a tender offer or exchange offer for outstanding Rockville Common Stock that has been publicly disclosed (other than by United or an affiliate of United) within ten (10) Business Days after the commencement of such tender or exchange offer, in any such case whether or not permitted by the terms hereof, (ii) (A) recommended or endorsed an Acquisition Proposal, or (B) failed to issue a press release announcing its opposition to such Acquisition Proposal within ten (10) Business Days after an Acquisition Proposal is publicly announced, or (iii) breached its obligations under Section 6.3 or 6.12 in any material respect;

(f) by Rockville, if the Board of Directors of United shall have (i) failed to recommend in the Joint Proxy Statement that the stockholders of United approve this Agreement, or withdrawn, modified or qualified such recommendation in a manner adverse to Rockville, or resolved to do so, or failed to recommend against acceptance of a tender offer or exchange offer for outstanding United Common Stock that has been publicly disclosed (other than by Rockville or an affiliate of Rockville) within ten (10) Business Days after the commencement of such tender or exchange offer, in any such case whether or not permitted by the terms hereof, (ii) (A) recommended or endorsed an Acquisition Proposal, or (B) failed to issue a press release announcing its opposition to such Acquisition Proposal within ten (10) Business Days after an Acquisition Proposal is publicly announced or (iii) breached its obligations under Section 6.3 or 6.12 in any material respect; or

(g) by either United or Rockville, if either United or Rockville shall have failed to obtain the Requisite United Vote or the Requisite Rockville Vote at the United Meeting or the Rockville Meeting, as applicable.

8.2 Effect of Termination.

(a) In the event of termination of this Agreement by either Rockville or United as provided in Section 8.1, this Agreement shall forthwith become void and have no effect, and none of Rockville, United, any of their respective Subsidiaries or any of the officers or directors of any of them shall have any liability of any nature whatsoever hereunder, or in connection with the transactions contemplated hereby, except that (i) Section 6.2(b), Section 6.13 and this Section 8.2 and Article IX (other than Section 9.1) shall survive any termination of this Agreement, and (ii) notwithstanding anything to the contrary contained in this Agreement, neither Rockville nor United shall be relieved or released from any liabilities or damages arising out of its willful and material breach of any provision of this Agreement.

(b) (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 made known to senior management of United or has been made directly to its stockholders generally or any

person shall have publicly announced (and not withdrawn) an Acquisition Proposal with respect to United and (A) thereafter this Agreement is terminated by either Rockville or United pursuant to Section 8.1(c) and United shall have failed to obtain the Requisite United Vote at the duly convened United Meeting or any adjournment or postponement thereof at which a vote on the approval of this Agreement was taken or (B) thereafter this Agreement is terminated by Rockville pursuant to Section 8.1(d) (as a result of a willful breach of this Agreement), Section 8.1(f)(i), Section 8.1(f)(ii)(B), or Section 8.1(f)(iii), and (C) prior to the date that is twelve (12) months after the date of such termination, United 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 United shall, on the earlier of the date it enters into such definitive agreement and the date of consummation of such transaction, pay Rockville, by wire transfer of same day funds, a fee equal to $15,000,000 (the “Termination Fee”); provided, that for purposes of this Section 8.2(b), all references in the definition of Acquisition Proposal to “25%” shall instead refer to “50%”.

(ii) In the event that this Agreement is terminated by Rockville pursuant to Section 8.1(f)(ii)(A), then United shall pay Rockville, by wire transfer of same day funds, a fee equal to 50% of the Termination Fee on the date of termination, and an additional fee equal to 50% of the Termination Fee on the earlier of the date United enters into a definitive agreement or consummates a transaction involving the Acquisition Proposal referenced in Section 8.1(f)(ii)(A) (or involving any other Acquisition Proposal with respect to which United enters into a definitive agreement or with respect to which United consummates a transaction, in either case prior to the date that is twelve (12) months after this Agreement is terminated).

(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 made known to senior management of Rockville or has been made directly to its stockholders generally or any person shall have publicly announced (and not withdrawn) an Acquisition Proposal with respect to Rockville and (A) thereafter this Agreement is terminated by either Rockville or United pursuant to Section 8.1(c) and Rockville shall have failed to obtain the Requisite Rockville Vote at the duly convened Rockville Meeting or any adjournment or postponement thereof at which a vote on the approval of this Agreement was taken or (B) thereafter this Agreement is terminated by United pursuant to Section 8.1(d) (as a result of a willful breach of this Agreement), Section 8.1(e)(i), Section 8.1(e)(ii)(B), or Section 8.1(e)(iii), and (C) prior to the date that is twelve (12) months after the date of such termination, Rockville 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 Rockville shall, on the earlier of the date it enters into such definitive agreement and the date of consummation of such transaction, pay United the $15,000,000 Termination Fee by wire transfer of same day funds; provided, that for purposes of this Section 8.2(c), all references in the definition of Acquisition Proposal to “25%” shall instead refer to “50%”.

(ii) In the event that this Agreement is terminated by United pursuant to Section 8.1(e)(ii)(A), then Rockville shall pay United, by wire transfer of same day funds, a fee equal to 50% of the Termination Fee on the date of termination, and an additional fee equal to 50% of the Termination Fee on the earlier of the date Rockville enters into a definitive

agreement or consummates a transaction involving the Acquisition Proposal referenced in Section 8.1(e)(ii)(A) (or involving any other Acquisition Proposal with respect to which Rockville enters into a definitive agreement or with respect to which Rockville consummates a transaction, in either case prior to the date that is twelve (12) months after this Agreement is terminated).

(d) Notwithstanding anything to the contrary herein, but without limiting the right of any party to recover liabilities or damages, the maximum aggregate amount of fees payable by a single party under this Section 8.2 shall be equal to the Termination Fee. Each of United and Rockville agrees that, upon termination of this Agreement under circumstances where the Termination Fee is payable to it and such Termination Fee is paid in full, it shall be precluded from any other remedy against the other party in connection with this Agreement or the transactions contemplated hereby, at law or in equity or otherwise, and it shall not seek to obtain any recovery, judgment, or damages of any kind, including consequential, indirect, or punitive damages, against the other party or any of the other party's Subsidiaries or any of their respective directors, officers, employees, partners, managers, members, shareholders or affiliates or their respective Representatives in connection with this Agreement or the transactions contemplated hereby.

(e) Each of Rockville and United 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 Rockville or United, 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 Rockville or United, 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 at a rate per annum equal to the “prime rate” (as announced by JPMorgan Chase & Co. or any successor thereto) in effect 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.

8.3 Amendment. Subject to compliance with applicable law, this Agreement may be amended by the parties hereto, by action taken or authorized by their respective Boards of Directors, at any time before or after approval of the matters presented in connection with Merger by the stockholders of Rockville and United; provided, however, that after approval of this Agreement by the respective stockholders of Rockville or United, there may not be, without further approval of such stockholders, any amendment of this Agreement that requires further approval under applicable law. This Agreement may not be amended except by an instrument in writing signed on behalf of each of the parties hereto.

8.4 Extension; Waiver. At any time prior to the Effective Time, the parties hereto, by action taken or authorized by their respective Boards of Directors, may, to the extent legally allowed, (a) extend the time for the performance of any of the obligations or other acts of the other parties hereto, (b) waive any inaccuracies in the representations and warranties contained

herein or in any document delivered pursuant hereto, and (c) waive compliance with any of the agreements or satisfaction of any conditions contained herein; provided, however, that after approval of this Agreement by the respective stockholders of Rockville or United, there may not be, without further approval of such stockholders, any extension or waiver of this Agreement or any portion thereof that requires further approval under applicable law. Any agreement on the part of a party hereto to any such extension or waiver shall be valid only if set forth in a written instrument signed on behalf of such party, but such extension or waiver or failure to insist on strict compliance with an obligation, covenant, agreement or condition shall not operate as a waiver of, or estoppel with respect to, any subsequent or other failure.

In some instances, the representations and warranties in this Agreement may represent an allocation among the parties hereto of risks associated with particular matters regardless of the knowledge of any of the parties hereto. Consequently, persons other than the parties may not rely upon the representations and warranties in this Agreement as characterizations of actual facts or circumstances as of the date of this Agreement or as of any other date.

The Former United Directors and Former Rockville Directors shall be apportioned among the classes of the Board of Directors as nearly evenly as is possible.

consist of an equal number of Former Rockville Directors and Former United Directors. Following the expiration of the Three-Year Period (for the avoidance of doubt, the election of Directors at the Third Annual Meeting shall be deemed for purposes of these Bylaws to follow the expiration of the Three-Year Period, and the provisions of this sentence shall apply to such election), the number of Directors of the Corporation shall be as determined by a two-thirds vote of the entire Board of Directors, and the requirement to have an equal number of Former Rockville Directors and Former United Directors shall expire.

(c) Until the expiration of the Three-Year Period, the provisions of this Section 2 may be modified, amended or repealed, and any Bylaw provision inconsistent with the provisions of this Section 2 may be adopted, only by an affirmative vote of at least two-thirds of the full Board of Directors.
