ARTICLE III

CONVERSION OF SHARES AND OPTIONS

3.1 Exchange of CBI Common Stock; Merger Consideration. At the Effective Time, by virtue of the Merger and without any action on the part of NewAlliance, NAB, CBI, Cornerstone or the holders of any of the shares of CBI Common Stock, the Merger shall be effected in accordance with the following terms:

3.1.1 All shares of CBI Common Stock held in the treasury of CBI and each share of CBI Common Stock owned by NewAlliance or any direct or indirect wholly owned subsidiary of NewAlliance or of CBI immediately prior to the Effective Time (other than shares held in a fiduciary capacity or in connection with debts previously contracted) shall, at the Effective Time, cease to exist, and the certificates for such shares shall be canceled as promptly as practicable thereafter, and no payment or distribution shall be made in consideration therefore.

3.1.2 Each outstanding share of CBI Common Stock that under the terms of Section 3.2 is to be converted into the right to receive shares of NewAlliance Common Stock (the “Stock Election Consideration”) shall, subject to the provisions of Section 3.3 generally, be converted into and become the right to receive from NewAlliance 2.518 shares of NewAlliance Common Stock (the “Stock Election Price”).

3.1.3 Each outstanding share of CBI Common Stock that under the terms of Section 3.2 is to be converted into the right to receive cash (the “Cash Election Consideration”) shall, subject to the provisions of Section 3.1.7, be converted into the right to receive a cash payment of thirty five ($35.00) dollars (the “Cash Election Price”).

3.1.4 Each Option which remains issued and outstanding immediately prior to the Effective Time shall, by virtue of the Merger and without regard to any future vesting date thereof, be cancelled and converted into the right to receive a cash payment in an amount determined by multiplying (i) the positive difference, if any, between the Cash Election Price and the exercise price of such Option for each share of CBI Common Stock subject to such Option (the “Option Price”) by (ii) the number of shares of CBI Common Stock subject to such Option (this quotient shall be referred to as the “Option Consideration”).

The payment of the Option Consideration referred to in this Section 3.1.4 to each holder of an Option shall be subject to such holder executing such instruments of cancellation, as NewAlliance and CBI may reasonably deem appropriate. NewAlliance, NAB, CBI or Cornerstone shall make necessary tax withholdings from the Option Consideration, as they deem appropriate.

3.1.5 Notwithstanding anything to the contrary contained herein, no certificates or scrip representing fractional shares of NewAlliance Common Stock shall be issued upon the surrender for exchange of Certificates, no dividend or distribution with respect to NewAlliance Common Stock shall be payable on or with respect to any fractional share interest, and such fractional share interests shall not entitle the owner thereof to vote or to any other rights of a stockholder of NewAlliance. In lieu of the issuance of any such fractional share, NewAlliance shall pay to each former holder of CBI Common Stock who otherwise would be entitled to receive a fractional share of NewAlliance Common Stock, an amount in cash determined by multiplying the Cash Election Price by the fraction of a share of NewAlliance Common Stock which such holder would otherwise be entitled to receive pursuant to Section 3.1.3 hereof (the “Fractional Share Consideration”). No interest will be paid on the cash that the holders of such fractional shares shall be entitled to receive upon such delivery. For purposes of determining any fractional share interest, all shares of CBI Common Stock owned by a CBI shareholder shall be combined so as to calculate the maximum number of whole shares of NewAlliance Common Stock issuable to such CBI shareholder.

The Stock Election Consideration, the Cash Election Consideration and the Fractional Share Consideration shall be referred to as the “Stock Merger Consideration,” and the Stock Merger Consideration and the Option Consideration are sometimes referred to collectively as the “Merger Consideration.”

3.1.6 After the Effective Time, shares of CBI Common Stock shall be no longer outstanding and shall automatically be canceled and shall cease to exist, and shall thereafter by operation of this Section 3.1.6 be a right to receive the Merger Consideration.

3.1.7 Notwithstanding any other provision of this Agreement to the contrary, if the tax opinion referred to in Section 9.1.5 cannot be rendered because the counsel charged with providing such opinion reasonably determines that the Merger may not satisfy the continuity of interest requirements applicable to reorganizations under Section 368(a) of the Code, then NewAlliance shall reduce the aggregate number of Cash Election Shares, and thereby the aggregate Cash Election Consideration, by the minimum extent necessary to enable such tax opinion to be rendered, and correspondingly increase the aggregate number of shares of CBI Common Stock to be converted into the Stock Election Price.

3.1.8 Each unvested restricted share of CBI Common Stock granted under the CBI Stock Plans which is outstanding immediately prior to the Effective Time shall vest and become free of restrictions at the close of business on the day immediately preceding the Effective Date or such earlier date as may be agreed to by NewAlliance.

3.2 Proration and Election Procedures. The Parties acknowledge that for United States income tax purposes it is intended that the Merger shall qualify as a reorganization under the provisions of Section 368(a) of the Code, and this Agreement is intended to be and is adopted as a plan of reorganization within the meaning of Section 368 of the Code. Consistent with that intent, notwithstanding any provision of this Agreement to the contrary, the aggregate Merger Consideration payable to all holders of CBI Common Stock shall include such number of shares of NewAlliance Common Stock as is necessary in order that the aggregate number of shares of CBI Common Stock exchanged through the Merger for shares of NewAlliance Common Stock is seventy percent (70%) of the aggregate of (i) the total number of shares of CBI Common Stock issued and outstanding and (ii) the total number of shares of CBI Common Stock subject to Options immediately prior to the Effective Time (the “Stock Conversion Number”). Subject to the Stock Conversion Number, holders of CBI Common Stock may elect to receive shares of NewAlliance Common Stock or the Cash Election Price in exchange for their shares of CBI Common Stock in accordance with the following procedures.

3.2.1 An election form (“Election Form”) will be sent by NewAlliance no later than fifteen (15) Business Days and no earlier than thirty (30) Business Days prior to the expected Effective Time (provided that it need not be sent until the approvals from the Bank Regulators as set forth in Section 8.3 have been obtained) to each holder of record of CBI Common Stock permitting such holder (or in the case of nominee record holders, the beneficial owner through proper instructions and documentation) to elect to receive, subject to the pro-ration procedures described in Section 3.2.2, (i) all NewAlliance Common Stock with respect to each share of such holder’s CBI Common Stock, as provided herein (the “Stock

Election Shares”); (ii) all cash with respect to each share of such holder’s CBI Common Stock, as provided herein (the “Cash Election Shares”) or (iii) a combination of Stock Merger Consideration consisting of 70% Stock Election Consideration and 30% Cash Election Consideration with respect to each share of such holder’s CBI Common Stock, as provided herein. Any shares of CBI Common Stock with respect to which the holder thereof shall not, as of the Election Deadline, have made such an election by submission to the Exchange Agent on an effective, properly completed Election Form (“Non-Election Shares”) shall be deemed to have elected the Cash Election Consideration and shall be converted into the Cash Election Price in accordance with Section 3.1.3, subject to the pro-ration procedures described in Section 3.2.2.

3.2.2 The term “Election Deadline”, as used below, shall mean 5:00 p.m., Eastern time, on the fifteenth (15^th) Business Day following but not including the date of mailing of the Election Form or such other date as NewAlliance and CBI shall mutually agree upon, provided in any event, the Election Deadline shall be at or before the Effective Time. Any election to receive NewAlliance Common Stock or cash shall have been properly made only if the Exchange Agent shall have actually received a properly completed Election Form by the Election Deadline. Any Election Form may be revoked or changed by the person submitting such Election Form to the Exchange Agent by written notice to the Exchange Agent only if such notice is actually received, including by facsimile, by the Exchange Agent at or prior to the Election Deadline. The Certificate or Certificates representing CBI Common Stock relating to any revoked Election Form shall be promptly returned without charge to the person submitting the Election Form to the Exchange Agent. The Exchange Agent shall have discretion to determine when any election, modification or revocation is received and whether any such election, modification or revocation has been properly made. Within five (5) Business Days after the Election Deadline, the Exchange Agent shall calculate the allocation, if any, among holders of CBI Common Stock of rights to receive the Stock Election Price and the Cash Election Price as follows:

If the number of Stock Election Shares does not equal the Stock Conversion Number, then the Stock Election Shares and the Cash Election Shares will be converted into the right to receive NewAlliance Common Stock and cash in the following manner:

(a) If the aggregate number of Stock Election Shares (the “Stock Election Number”) exceeds the Stock Conversion Number, then all CBI Cash Election Shares and all Non-Election Shares of each holder thereof shall be converted into the right to receive the Cash Consideration, and Stock Election Shares of each holder thereof will be converted into the right to receive the Stock Consideration in respect of that number of Stock Election Shares equal to the product obtained by multiplying (x) the number of Stock Election Shares held by such holder by (y) a fraction, the numerator of which is the Stock Conversion Number and the denominator of which is the Stock Election Number, with the remaining number of such holder’s Stock Election Shares being converted into the right to receive the Cash Election Consideration; and

(b) If the Stock Election Number is less than the Stock Conversion Number (the amount by which the Stock Conversion Number exceeds the Stock Election Number being referred to herein as the “Shortfall Number”), then all Stock Election Shares shall be converted into the right to receive the Stock Consideration and the Non-Election Shares and Cash Election Shares shall be treated in the following manner:

(i) If the Shortfall Number is less than or equal to the number of Non-Election Shares, then all Cash Election Shares shall be converted into the right to receive the Cash Election Consideration and the Non-Election Shares of each holder thereof shall be converted into the right to receive the Stock Consideration in respect of that number of Non-Election Shares equal to the product obtained by multiplying (x) the number of Non-Election Shares held by such holder by (y) a fraction, the numerator of which is the Shortfall Number and the denominator of which is the total number of Non-Election Shares, with the remaining number of such holder’s Non-Election Shares being converted into the right to receive the Cash Election Consideration; or

(ii) If the Shortfall Number exceeds the number of Non-Election Shares, then all Non-Election Shares shall be converted into the right to receive the Stock Election Consideration, and Cash Election Shares of each holder thereof shall be converted into the right to receive the Stock Election Consideration in respect of that number of Cash Election Shares equal to the product obtained by multiplying (x) the number of Cash Election Shares held by such holder by (y) a fraction, the numerator of which is the amount by which (1) the Shortfall Number exceeds (2) the total number of Non-Election Shares and the denominator of which is the total number of Cash Election Shares, with the remaining number of such holder’s Cash Election Shares being converted into the right to receive the Cash Election Consideration.

3.3 Procedures for Exchange of CBI Common Stock.

3.3.1 NewAlliance to Make Merger Consideration Available. At or before the Effective Time, NewAlliance shall deposit, or shall cause to be deposited, with the Exchange Agent for the benefit of the holders of CBI Common Stock, for exchange in accordance with this Section 3.3, certificates representing the shares of NewAlliance Common Stock sufficient to pay the Stock Election Price and an estimated amount of cash sufficient to pay the aggregate Option Consideration, the aggregate Cash Election Consideration and the aggregate Fractional Share Consideration payable hereunder (such cash and certificates for shares of NewAlliance Common Stock, together with any dividends or distributions with respect thereto, being hereinafter referred to as the “Exchange Fund”).

3.3.2 Exchange of Certificates. Within five (5) business days after the Effective Time, NewAlliance shall take all steps necessary to cause the Exchange Agent to mail to each holder of a Certificate or Certificates, a form letter of transmittal for return to the Exchange Agent and instructions for use in effecting the surrender of the Certificates for, as the case may be, certificates representing the shares of NewAlliance Common Stock, cash in respect of the Cash Election Price, and cash in respect of the Fractional Share Price. The letter of transmittal (which shall be subject to the reasonable approval of CBI) shall specify that delivery shall be effected, and risk of loss and title to the Certificates shall pass, only upon delivery of the Certificates to the Exchange Agent. Upon proper surrender of a Certificate for exchange and cancellation to the Exchange Agent, together with a properly completed

letter of transmittal, duly executed, the holder of such Certificate shall be entitled to receive in exchange therefore, as applicable, (i) a certificate representing that number of shares (if any) of NewAlliance Common Stock to which such former holder of CBI Common Stock shall have become entitled pursuant to the provisions of Section 3.1.2 hereof, (ii) a check representing that amount of cash (if any) to which such former holder of CBI Common Stock shall have become entitled in respect of the Cash Election Price pursuant to the provisions of Section 3.1.3 hereof, and (iii) a check representing the amount of cash (if any) payable in respect of the Fractional Share Price, which such former holder has the right to receive in respect of the Certificate surrendered pursuant to the provisions of Section 3.1.5, and the Certificate so surrendered shall forthwith be cancelled. No interest will be paid or accrued on the cash payable in lieu of fractional shares. Certificates surrendered for exchange by any person who is an “affiliate” of CBI for purposes of Rule 145(c) under the Securities Act shall not be exchanged for certificates representing shares of NewAlliance Common Stock until NewAlliance has received the written agreement of such person contemplated by Section 8.4 hereof.

3.3.3 Rights of Certificate Holders after the Effective Time. The holder of a Certificate that prior to the Merger represented issued and outstanding CBI Common Stock shall have no rights, after the Effective Time, with respect to such CBI Common Stock except to surrender the Certificate in exchange for the Merger Consideration as provided in this Agreement. No dividends or other distributions declared after the Effective Time with respect to NewAlliance Common Stock shall be paid to the holder of any unsurrendered Certificate until the holder thereof shall surrender such Certificate in accordance with Section 3.3. After the surrender of a Certificate in accordance with Section 3.3, 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 shares of NewAlliance Common Stock represented by such Certificate.

3.3.4 Surrender by Person Other than Record Holders. If the Person surrendering a Certificate and signing the accompanying letter of transmittal is not the record holder thereof, then it shall be a condition of the payment of the Stock Merger Consideration that: (i) such Certificate is properly endorsed to such Person or is accompanied by appropriate stock powers, in either case signed exactly as the name of the record holder appears on such Certificate, and is otherwise in proper form for transfer, or is accompanied by appropriate evidence of the authority of the Person surrendering such Certificate and signing the letter of transmittal to do so on behalf of the record holder; and (ii) the Person requesting such exchange shall pay to the Exchange Agent in advance any transfer or other taxes required by reason of the payment to a person other than the registered holder of the Certificate surrendered, or required for any other reason, or shall establish to the satisfaction of the Exchange Agent that such tax has been paid or is not payable.

3.3.5 Closing of Transfer Books. From and after the Effective Time, there shall be no transfers on the stock transfer books of CBI of the CBI Common Stock that were 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 exchanged for the Merger Consideration and canceled as provided in this Section 3.3.

3.3.6 Return of Exchange Fund. At any time following the twelve (12) month period after the Effective Time, NewAlliance shall be entitled to require the Exchange Agent to deliver to it any portions of the Exchange Fund which had been made available to the Exchange Agent and not disbursed to holders of Certificates (including, without limitation, all interest and other income received by the Exchange Agent in respect of all funds made available to it), and thereafter such holders shall be entitled to look to NewAlliance (subject to abandoned property, escheat and other similar laws) with respect to any Merger Consideration that may be payable upon due surrender of the Certificates held by them. Notwithstanding the foregoing, neither NewAlliance nor the Exchange Agent shall be liable to any holder of a Certificate for any Merger Consideration delivered in respect of such Certificate to a public official pursuant to any abandoned property, escheat or other similar law.

3.3.7 Lost, Stolen or Destroyed Certificates. 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 NewAlliance, the posting by such person of a bond in such amount as NewAlliance may reasonably direct as indemnity against any claim that may be made against it with respect to such Certificate, NewAlliance or the Exchange Agent will issue in exchange for such lost, stolen or destroyed Certificate the Merger Consideration deliverable in respect thereof.

3.3.8 Withholding. NewAlliance or the Exchange Agent will be entitled to deduct and withhold from the consideration otherwise payable pursuant to this Agreement or the transactions contemplated hereby to any holder of CBI Common Stock such amounts as NewAlliance (or any Affiliate thereof) or the Exchange Agent are required to deduct and withhold with respect to the making of such payment under the Code, or any applicable provision of U.S. federal, state, local or non-U.S. tax law. To the extent that such amounts are properly withheld by NewAlliance or the Exchange Agent, such withheld amounts will be treated for all purposes of this Agreement as having been paid to the holder of the CBI Common Stock in respect of whom such deduction and withholding were made by NewAlliance or the Exchange Agent.

3.3.9 Payment of Option Consideration. Immediately prior to the Effective Time, CBI, subject to a review of the calculation by NewAlliance, shall issue and deliver a check representing the Option Price to the holders of the Options, all of which Options shall have been cancelled in connection with Section 3.1.4 above.

3.3.10 Reservation of Shares. Effective upon the date of this Agreement, NewAlliance shall reserve for issuance a sufficient number of shares of the NewAlliance Common Stock for the purpose of issuing shares of NewAlliance Common Stock to the CBI shareholders in accordance with this Article III.

3.3.11 Listing of Additional Shares. Prior to the Effective Time, NewAlliance shall notify the NYSE of the additional shares of NewAlliance Common Stock to be issued by NewAlliance in exchange for the shares of CBI Common Stock.

CBI shall use all reasonable best efforts in good faith to obtain as soon as practicable all consents and approvals of any other persons necessary or desirable for the consummation of the transactions contemplated by this Agreement and the Bank Merger Agreement. Without limiting the generality of the foregoing, CBI shall utilize the services of a professional proxy-soliciting firm to help obtain the shareholder vote required to be obtained by it hereunder.

6.8 Reasonable Best Efforts. Subject to the terms and conditions herein provided, CBI shall use its reasonable best efforts in good faith to take, or cause to be taken, all action and to do, or cause to be done, all things necessary, proper or advisable under applicable laws and regulations to consummate and make effective the transactions contemplated by this Agreement and the Bank Merger Agreement.

6.9 Failure to Fulfill Conditions. In the event that CBI determines that a condition to its obligation to complete the Merger or the Bank Merger cannot be fulfilled and that it will not waive that condition, it will promptly so notify NewAlliance.

6.10 Acquisition Proposals. (a) CBI agrees that neither it nor any of CBI’s Subsidiaries shall, and that it shall direct and use its reasonable best efforts in good faith to cause its and each such Subsidiary’s directors, officers, employees, agents and representatives not to, directly or indirectly, initiate, solicit, knowingly encourage or otherwise facilitate any inquiries or the making of any proposal or offer with respect to an Acquisition Proposal. CBI further agrees that neither it nor any of its Subsidiaries shall, and that it shall direct and use its reasonable best efforts in good faith to cause its and each such Subsidiary’s directors, officers, employees, agents and representatives not to, directly or indirectly, engage in any negotiations concerning, or provide any confidential information or data to, or have any discussions with, any Person relating to an Acquisition Proposal, or otherwise knowingly facilitate any effort or attempt to make or implement an Acquisition Proposal; provided, however, that nothing contained in this Agreement shall prevent CBI or its Board of Directors from (A) complying with its disclosure obligations under federal or state law; (B) providing information in response to a request therefore by a Person who has made an unsolicited bona fide written Acquisition Proposal if the CBI Board of Directors receives from the Person so requesting such information an executed confidentiality agreement substantially similar to that entered into with NewAlliance; (C) engaging in any negotiations or discussions with any Person who has made an unsolicited bona fide written Acquisition Proposal or (D) recommending such an Acquisition Proposal to the shareholders of CBI, if and only to the extent that, in each such case referred to in clause (B), (C) or (D) above, (i) the CBI Board of Directors determines in good faith (after consultation with outside legal counsel) that such action would be required in order for its directors to comply with their respective fiduciary duties under applicable law, (ii) the CBI Board of Directors determines in good faith (after consultation with its financial advisor) that such Acquisition Proposal, if accepted, is reasonably likely to be consummated, taking into account all legal, financial and regulatory aspects of the proposal and the Person making the proposal and would, if consummated, result in a transaction more favorable to CBI’s shareholders from a financial point of view than the Merger, and (iii) the shareholders of CBI have not yet approved this Agreement at the CBI Shareholders Meeting. An Acquisition Proposal which is received and considered by CBI in compliance with this Section 6.10 and which meets the requirements set forth in clause (D) of the preceding sentence is herein referred to as a “Superior Proposal.” CBI agrees that it will immediately cease and cause to be terminated any existing activities, discussions or negotiations with any parties conducted heretofore with respect to any Acquisition Proposals. CBI agrees that it will notify NewAlliance orally within one (1) Business Day, with written notice to follow within three (3) Business Days thereafter, if any such inquiries, proposals or offers are received by, any such information is requested from, or any such discussions or negotiations are sought to be initiated or continued with CBI or any of its representatives after the date hereof, and the identity of the person making such inquiry, proposal or offer and the substance thereof and will keep NewAlliance informed of any material developments with respect thereto immediately upon the occurrence thereof.

(b) In the event that the Board of Directors of CBI determines in good faith, after consultation with its financial advisor and upon advice from outside counsel, that it desires to accept a Superior Proposal, it shall notify NewAlliance in writing of its intent to terminate this Agreement in order to enter into an acquisition agreement with respect to, or recommend acceptance of, the Superior Proposal. Such notice shall specify all of the terms and conditions of such Superior Proposal and identify the Person making such Superior Proposal. NewAlliance shall have five Business Days to evaluate and respond to CBI’s notice. If NewAlliance delivers to CBI in writing prior to the expiration of the five Business Day

period provided above (x) an amendment to Sections 3.1.2, 3.1.3 and 3.1.4 of this Agreement increasing the Merger Consideration to an amount, and (y) adjusting other material terms and conditions such that they are at least equal to that of such Superior Proposal (the “NewAlliance Amendment”), as determined by CBI’s Board of Directors in the good faith exercise of its fiduciary duties after consultation with its financial advisors and counsel, then CBI shall accept the NewAlliance Amendment and reject the Superior Proposal. CBI shall have five Business Days to evaluate the NewAlliance Amendment.

(c) In the event that the Board of Directors of CBI determines under Section 6.10(b) that the NewAlliance Amendment is not at least equal to the Superior Proposal, CBI can terminate this Agreement in order to execute an Acquisition Agreement with respect to, or to allow its Board to adopt a resolution recommending acceptance to CBI’s shareholders of, the Superior Proposal as provided in Section 11.1.9.

6.11 Board of Directors and Committee Meetings. Commencing with the first meeting after the filing of the Merger Registration Statement with the SEC, CBI and Cornerstone shall permit a representative of NewAlliance to attend any meeting of the Board of Directors of CBI and/or Cornerstone or any committees thereof (provided that neither CBI nor Cornerstone shall be required to permit the NewAlliance representative to remain present during any confidential discussion of this Agreement and the transactions contemplated hereby or any third party proposal to acquire control of CBI or Cornerstone). CBI shall provide to NewAlliance (a) notice of any and all such meetings, which notice shall be no less timely than the notice required to be provided to CBI’s or Cornerstone’s directors, and (b) copies of all written materials (i) accompanying any such notices, (ii) presented to the participants of any and all such meetings, and (iii) copies of drafts of meeting minutes and credit memoranda produced with respect to such meeting at such time as customarily provided to CBI’s or Cornerstone’s directors, excluding, however, any materials pertaining to NewAlliance, the transactions contemplated by this Agreement, or any third party proposal to acquire a controlling interest in CBI or Cornerstone.

6.12 Reserves and Merger-Related Costs. Not earlier than sixty (60) days before the anticipated Effective Time, CBI shall establish such additional accruals and reserves as may be necessary to conform the accounting reserve practices and methods (including credit loss practices and methods) of CBI and Cornerstone to those of NewAlliance (as such practices and methods are to be applied to CBI and Cornerstone from and after the Closing Date) and NewAlliance’s plans with respect to the conduct of the business of CBI and Cornerstone following the Merger and otherwise to reflect Merger-related expenses and costs incurred by CBI, provided, however, that CBI shall not be required to take such action unless NewAlliance agrees in writing that (i) all conditions to closing set forth in Sections 9.1 and 9.3 have been satisfied or waived (except for the expiration of any applicable waiting periods relating to any governmental approvals) and (ii) all opinions, certificates, letters and other documents to be received by NewAlliance, CBI or Cornerstone on the Closing Date have been delivered into escrow fully signed, and subject only to the expiration of any governmental waiting period. Prior to the delivery by NewAlliance of the writing referred to in the preceding sentence, CBI shall provide NewAlliance a written statement, certified without personal liability by the chief executive officer of CBI and dated the date of such writing, that the representation made in Section 4.22.1 hereof with respect to CBI’s allowance for possible loan losses is true as of such date in all material respects or, alternatively, setting forth

in detail the circumstances that prevent such representation from being true as of such date; and no accrual or reserve made by CBI or any CBI Subsidiary pursuant to this subsection, or any litigation or regulatory proceeding arising out of any such accrual or reserve, shall constitute a breach of this Agreement within the meaning of Section 11.1.2 hereof. No action shall be required to be taken by CBI pursuant to this Section 6.12 if, in the opinion of CBI’s independent auditors, such action would contravene GAAP.

6.13 Transaction Expenses of CBI.

6.13.1 For planning purposes, CBI shall, within thirty (30) days from the date hereof, provide NewAlliance with CBI’s estimated budget of transaction-related expenses reasonably anticipated to be payable by CBI in connection with this transaction, including the fees and expenses of counsel, accountants, investment bankers and other professionals. CBI shall promptly notify NewAlliance if or when it determines that it expects to exceed its budget.

6.13.2 Promptly after the execution of this Agreement, CBI shall ask all of its attorneys and other professionals to render current and correct invoices for all unbilled time and disbursements. CBI shall accrue and/or pay all of such amounts that are actually due and owing as soon as possible.

6.13.3 CBI shall advise NewAlliance monthly of all out-of-pocket expenses that CBI has incurred in connection with the transactions contemplated by this Agreement (including the Bank Merger).

6.14 Certain Policies of CBI. Upon the request of NewAlliance and NAB, CBI and Cornerstone shall, consistent with GAAP and regulatory accounting principles, use their reasonable best efforts to record certain accounting adjustments to the policies of CBI and Cornerstone so as to reflect the policies of NewAlliance and NAB and to implement internal control procedures which are consistent with NewAlliance’s and NAB’s current internal control procedures to allow NewAlliance to fulfill its reporting requirement under Section 404 of the Xxxxxxxx-Xxxxx Act of 2002; provided, however, that CBI and Cornerstone shall not be obligated to record any such accounting adjustments or implement any internal control procedures pursuant to this Section 6.14 unless and until CBI and Cornerstone shall be satisfied that the conditions to the obligation of the parties to consummate the Merger will be satisfied or waived on or before the Effective Time and in no event until the day prior to the Effective Date. CBI’s and Cornerstone’s representations, warranties and covenants contained in this Agreement shall not be deemed to be untrue or breached in any respect for any purpose as a consequence of any modifications or changes undertaken solely on account of this Section 6.14.

6.15 Amendment of CBI Employee Plans. CBI and Cornerstone agree to amend each CBI Employee Plan subject to Section 409A of the Code to comply with Section 409A of the Code prior to the Effective Time. CBI and Cornerstone shall provide NAB and its counsel with appropriate opportunity to review and comment on such amendments prior to the time they are adopted.

6.16 Cornerstone Bank Severance Plan. Cornerstone has adopted and NAB agrees to honor the Cornerstone Bank Severance Plan in the form attached as Schedule 6.16 of the CBI DISCLOSURE SCHEDULE.

6.17 Termination of CBI Dividend Reinvestment Plan. CBI shall take all action necessary to terminate the CBI Dividend Reinvestment Plan as of the date hereof; provided, however that such termination shall not prohibit CBI from issuing up to 1,500 additional shares of CBI Common Stock to satisfy its obligations under and in accordance with the terms of the CBI Dividend Reinvestment Plan for a thirty (30) day period after such termination.

ARTICLE VII

COVENANTS OF NEWALLIANCE AND NAB

From time to time prior to the Effective Time, NewAlliance will promptly supplement or amend the NEWALLIANCE DISCLOSURE SCHEDULE delivered in connection herewith with respect to any material matter hereafter arising which, if existing, occurring or known at the date of this Agreement, would have been required to be set forth or described in such NEWALLIANCE DISCLOSURE SCHEDULE or which is necessary to correct any information in such NEWALLIANCE DISCLOSURE SCHEDULE which has been rendered materially inaccurate thereby. No supplement or amendment to such NEWALLIANCE DISCLOSURE SCHEDULE shall have any effect for the purpose of determining satisfaction of the conditions set forth in Article IX.

7.2 Consents and Approvals of Third Parties. NewAlliance shall use all reasonable best efforts in good faith to obtain as soon as practicable all consents and approvals of any other Persons necessary or desirable for the consummation of the transactions contemplated by this Agreement and the Bank Merger Agreement.

7.3 Reasonable Best Efforts. Subject to the terms and conditions herein provided, NewAlliance shall use all reasonable best efforts in good faith to take, or cause to be taken, all action and to do, or cause to be done, all things necessary, proper or advisable under applicable laws and regulations to consummate and make effective the transactions contemplated by this Agreement and the Bank Merger Agreement.

7.4 Failure to Fulfill Conditions. In the event that NewAlliance determines that a condition to its obligation to complete the Merger or the Bank Merger Agreement cannot be fulfilled and that it will not waive that condition, it will promptly so notify CBI.

7.5 Employees and Employee Benefits.

7.5.1 NAB anticipates employing branch office customer service employees of Cornerstone and such other employees of Cornerstone as NAB shall reasonably require for the conduct of NAB’s business following the Effective Time. NAB may, in its sole discretion, pay a retention bonus to certain key employees in an amount to be determined by NAB in its sole discretion, in the event such employee remains in the employ of Cornerstone through the Effective Time and is not offered permanent employment with NAB.

7.5.2 Except as set forth below, each employee of Cornerstone who remains employed by NAB following the Effective Time (each, a “Continuing Employee”) shall be entitled to participate in (i) such of the employee benefit plans, deferred compensation arrangements, bonus or incentive plans and/or other compensation and benefit plans of Cornerstone that NAB may continue for the benefit of Continuing Employees following the Effective Time and (ii) whatever employee benefit plans and other compensation and benefit plans that NAB may maintain for the benefit of its similarly situated employees, if such Continuing Employee is not otherwise then participating in a similar plan of Cornerstone then provided by NAB, in each case other than as set forth in the Retention Agreements referred to in Section 7.5.4 hereof. The parties hereto acknowledge that Continuing Employees shall not be entitled to receive any specific level of grants under any stock option plan or restricted stock plan which NewAlliance may implement subsequent to the date of this Agreement. Any grants that may be made to the Continuing Employees under any of such plans will be subject to the sole discretion of the Board of Directors of NewAlliance or the committee administering such plans. Continuing Employees shall be eligible to participate in all NewAlliance employee benefit plans in accordance with plan documents, including, but not limited to, NewAlliance’s 401(k) plan, employee stock ownership plan and defined benefit plan. Continuing Employees shall not receive credit for service with CBI and the CBI Subsidiaries under any existing NewAlliance employee plan or any NewAlliance benefit plan in which such employees would be eligible to enroll for any purposes under any NewAlliance benefit plan, except as set forth below. With respect to the NewAlliance defined benefit pension plan and employee stock ownership plan, each Continuing Employee shall be credited with service as a Cornerstone employee for purposes of determining eligibility to participate under such plans (but not for purposes of benefit accrual or vesting). With respect to any NewAlliance plan which is a health, life or disability insurance plan, each Continuing Employee shall be credited with service as a Cornerstone employee for purposes of determining eligibility under such plans and shall not be subject to any pre-existing condition limitation for conditions covered under such plans, and each such plan which provides health insurance benefits shall honor any deductible and out-of-pocket expenses incurred under any comparable Cornerstone plan for the plan year in which the Effective Time occurs. Nothing herein shall limit the ability of NewAlliance to amend or terminate any of the CBI Employee Plans in accordance with their terms at any time after the Effective Time. At the Effective Time, NewAlliance shall become the plan sponsor of each CBI Employee Plan. CBI agrees to take or cause to be taken such actions as NewAlliance may reasonably request to give effect to such assumption. NewAlliance shall have the right and power at any time following the Effective Time to amend or terminate or cease benefit accruals under any CBI Employee Plan or cause it to be merged with or its assets and liabilities to be transferred to a similar plan maintained by NewAlliance.

7.5.3 Section 7.5.3 of the CBI DISCLOSURE SCHEDULE contains all employment and change of control, severance, deferred compensation, retirement, salary continuation and similar agreements, arrangements, policies or programs with any employee or director of CBI or any CBI Subsidiary (“Benefit Agreements”). At and following the Effective Time, NewAlliance shall honor, and the Surviving Corporation shall continue to be obligated to perform, in accordance with their terms, all benefit obligations of CBI existing

as of the Effective Time under the Benefit Agreements other than those employment agreements and change in control agreements covered by the Release, Consulting and Noncompetition Agreements or the Retention Agreements referenced in Section 7.5.4 hereof. NewAlliance acknowledges (i) that the consummation of the Merger will constitute a “change-in-control” of CBI for purposes of any of the Benefit Agreements of CBI (except where otherwise set forth in Section 7.5.3 of the CBI DISCLOSURE SCHEDULE). Any employee or director of CBI or any of its Subsidiaries who is a party to an agreement which has been set forth in Section 7.5.3 of the CBI DISCLOSURE SCHEDULE excluding the employment agreements and change in control agreements covered by the Release, Consulting and Noncompetition Agreements or the Retention Agreements referenced in Section 7.5.4 hereof (with the agreements not excluded referred to herein as the “Executive Agreements”) who becomes entitled to benefits thereunder shall be entitled to receive the cash benefits payable under such agreement at the time and in the amounts provided for by the agreement; provided, however, that the employee or director executes and delivers to NewAlliance an instrument in form and substance satisfactory to NewAlliance releasing NewAlliance and its affiliates from any further liability for monetary payments under such agreement. To the extent that an employee of CBI or any of its Subsidiaries is entitled to the continued receipt of health insurance, life insurance, disability insurance, or other similar fringe benefits pursuant to an Executive Agreement, and such employee becomes an officer, employee or consultant of NewAlliance or any of its Subsidiaries following the Effective Time and as a result becomes entitled to receive the same fringe benefits in his or her capacity as an officer, employee or consultant of NewAlliance or any of its Subsidiaries, then the fringe benefits provided to such person shall be deemed to be provided in connection with such person’s service as an officer, employee or consultant of NewAlliance or any of its Subsidiaries for so long as such person serves in such capacity and shall be in lieu of, and not in addition to (and for the sole purpose to avoid duplication of benefits), the same fringe benefits that would have otherwise been provided pursuant to the Executive Agreement.

7.5.4 Concurrently with the execution of this Agreement by the parties hereto, (i) each of Xxxxxxx X. Xxxxxxxxx, Xxxxxx X. Xxxxxxx, Xxxx X. Xxxx, Xxxxx X. Xxxxxxxx and Xxxxxxx Xxxxxxx shall enter into a Retention Agreement with CBI, Cornerstone and NAB substantially in the form of Exhibit C hereto, and (ii) each of Xxxxx X. Xxxxxxx and Xxxx X. Reader shall enter into a Release, Consulting and Noncompetition Agreement with CBI, Cornerstone, NewAlliance and NAB substantially in the form of Exhibit D hereto.

The dollar amounts to be paid to each of the officers named in this Section 7.5.4 and the titles of the officers who will enter into a Retention Agreement are set forth on Section 7.5.4 of the NEWALLIANCE DISCLOSURE SCHEDULE. In consideration of the amounts to be paid to the officers named in this Section 7.5.4 pursuant to their respective Retention Agreement and Release, Consulting and Noncompetition Agreement, CBI and Cornerstone agree that they will make no severance or other change in control payments or benefits to such officers pursuant to the existing employment or change of control agreements with such officers.

7.6 Directors and Officers Indemnification and Insurance.

7.6.1 NewAlliance shall maintain in effect for six (6) years following the Effective Time the current directors’ and officers’ liability insurance policies maintained by CBI and the CBI Subsidiaries (provided, that NewAlliance may substitute therefor policies of at least the same coverage containing terms and conditions which are not materially less favorable) with respect to matters occurring prior to the Effective Time; provided, however, that in no event shall NewAlliance be required to expend in the aggregate pursuant to this Section 7.6.1 more than 200% of the annual cost currently expended by CBI with respect to such insurance (the “Maximum Premium Amount”). In connection with the foregoing, CBI agrees to provide such insurer or substitute insurer with such representations as such insurer may request with respect to the reporting of any prior claims. Notwithstanding the above, CBI may, in consultation with NewAlliance, purchase “tail coverage” for a period of six (6) years following the Effective Time for its officers and directors provided the cost for such coverage in the aggregate does not exceed the Maximum Premium Amount. If such coverage is purchased, NewAlliance shall not be required to provide the insurance set forth in this Section 7.6.1.

7.6.2 NewAlliance shall, and/or shall cause the appropriate NewAlliance Subsidiary to, indemnify, defend and hold harmless each person who is now, or who has been at any time before the date hereof or who becomes before the Effective Time, an officer or director of CBI or Cornerstone (the “Indemnified Parties”) against all losses, claims, damages, costs, expenses (including reasonable attorney’s fees), liabilities or judgments or amounts that are paid in settlement (which settlement shall require the prior written consent of NewAlliance, which consent shall not be unreasonably withheld) of or in connection with any claim, action, suit, proceeding or investigation, whether civil, criminal, or administrative (each a “Claim”), in which an Indemnified Party is, or is threatened to be made, a party or witness in whole or in part or arising in whole or in part out of the fact that such person is or was a director, officer or employee of CBI or a CBI Subsidiary if such Claim pertains to any matter of fact arising, existing or occurring before the Effective Time (including, without limitation, the Merger and the other transactions contemplated hereby), regardless of whether such Claim is asserted or claimed before, or after, the Effective Time (the “Indemnified Liabilities”), to the fullest extent permitted under applicable state or federal law and under CBI’s Certificate of Incorporation and Bylaws. NewAlliance shall pay expenses, including reasonable attorney’s fees, in advance of the final disposition of any such action or proceeding to each Indemnified Party to the full extent permitted by applicable state or federal law upon receipt of an undertaking to repay such advance payments if he or she shall be adjudicated or determined not to be entitled to indemnification in the manner set forth below. Any Indemnified Party wishing to claim indemnification under this Section 7.6.2 upon learning of any Claim, shall notify NewAlliance (but the failure so to notify NewAlliance shall not relieve it from any liability which it may have under this Section 7.6.2, except to the extent such failure prejudices NewAlliance) and shall deliver to NewAlliance the undertaking referred to in the previous sentence. In the event of any such Claim (whether arising before or after the Effective Time) (1) NewAlliance shall have the right to assume the

defense thereof (in which event the Indemnified Parties will cooperate in the defense of any such matter) and upon such assumption NewAlliance shall not be liable to any Indemnified Party for any legal expenses of other counsel or any other expenses subsequently incurred by any Indemnified Party in connection with the defense thereof, except that if NewAlliance elects not to assume such defense, or counsel for the Indemnified Parties reasonably advises the Indemnified Parties that there are or may be (whether or not any have yet actually arisen) issues which raise conflicts of interest between NewAlliance and the Indemnified Parties, the Indemnified Parties may retain counsel reasonably satisfactory to them, and NewAlliance shall pay the reasonable fees and expenses of such counsel for the Indemnified Parties, (2) NewAlliance shall be obligated pursuant to this paragraph to pay for only one (1) firm of counsel for all Indemnified Parties whose reasonable fees and expenses shall be paid promptly as statements are received unless there is a conflict of interest that necessitates more than one (1) law firm, (3) NewAlliance shall not be liable for any settlement effected without its prior written consent (which consent shall not be unreasonably withheld), and (4) no Indemnified Party shall be entitled to indemnification hereunder with respect to a matter as to which (x) he shall have been adjudicated in any proceeding not to have acted in good faith and in a manner he reasonably believed to be in, or not opposed to, the best interests of CBI or any CBI Subsidiary, or (y) in the event that a proceeding is compromised or settled so as to impose any liability or obligation upon an Indemnified Party, if there is a determination that with respect to said matter said Indemnified Party did not act in good faith and in a manner he reasonably believed to be in, or not opposed to, the best interests of CBI or any CBI Subsidiary. The determination shall be made by a majority vote of a quorum consisting of the Directors of NewAlliance who are not involved in such proceeding.

7.7 Conduct of Business. Except with the written consent of CBI, during the period from the date of this Agreement to the earlier of the Effective Time or the termination of this Agreement, NewAlliance will operate its business, and it will cause each of the NewAlliance Subsidiaries to operate its business, only in the usual, regular and ordinary course of business; use its reasonable best efforts in good faith to preserve intact its business organization and assets, keep available the present services of the employees, maintain its rights and franchises, and preserve the goodwill of its customers and others with whom business relationships exist; and voluntarily take no action which would or be reasonably likely to (i) adversely affect the ability of NewAlliance or NAB to obtain any necessary approvals of Governmental Entities required for the transactions contemplated hereby or under the Bank Merger Agreement or increase the period of time necessary to obtain such approvals, or (ii) adversely affect its ability to perform its covenants and agreements under this Agreement or the Bank Merger Agreement.

7.8 Financial and Other Statements.

7.8.1 Promptly upon receipt thereof, NewAlliance will furnish to CBI copies of each annual, interim or special audit of the books of NewAlliance and the NewAlliance Subsidiaries made by its independent accountants and/or its internal auditors and copies of all internal control reports submitted to NewAlliance by such accountants and/or internal auditors in connection with each annual, interim or special audit of the financial statements of NewAlliance and the NewAlliance Subsidiaries made by such accountants and/or internal auditors.

7.8.2 As soon as reasonably available, but in no event later than the date such documents are filed with the SEC, NewAlliance will deliver to CBI any and all Securities Documents filed by it with the SEC under the Securities Laws. As soon as practicable, NewAlliance will furnish to CBI copies of all such financial statements and reports as it or any NewAlliance Subsidiary shall send to its shareholders, the FDIC, the FRB, the Department or any other regulatory authority, except as legally prohibited thereby.

7.8.3 NewAlliance will advise CBI promptly of the receipt of any examination report of any Bank Regulator with respect to the condition or activities of NewAlliance or any of the NewAlliance Subsidiaries.

7.8.4 NewAlliance will promptly furnish to CBI such additional financial data as CBI may reasonably request, including without limitation, detailed monthly loan reports.

7.9 Current Information. During the period from the date of this Agreement to the earlier of the Effective Time or the termination of this Agreement, NewAlliance will cause one or more of its representatives to confer with representatives of CBI and report on the general status of its ongoing operations at such times as CBI may reasonably request. NewAlliance will promptly notify CBI of any material change from the normal course of business of NewAlliance or NAB or in the operation of the properties of NewAlliance or NAB and, to the extent permitted by applicable law, of any governmental complaints, investigations or hearings (or communications indicating that the same may be contemplated), or the institution or the threat of material litigation involving NewAlliance or NAB.

7.10 Negative Covenants. NewAlliance agrees that from the date of this Agreement to the earlier of the Effective Time or the termination of this Agreement, except as otherwise specifically permitted or required by this Agreement, or consented to by CBI in writing which consent shall not unreasonably be withheld, conditioned or delayed, NewAlliance will not, and will cause each of the NewAlliance Subsidiaries not to;

(a) make any change in its accounting methods or practices, except changes as may be required by GAAP, PCAOB accounting pronouncements or by law or regulatory requirements;

(b) take any action that would result in the representations and warranties of NewAlliance and any NewAlliance Subsidiary contained in this Agreement not being true and correct in all material respects on the date of this Agreement or at the Closing Date;

(c) take any action that is intended or is reasonably likely to result in (x) any of its representations and warranties set forth in this Agreement being or becoming untrue in any material respect at the Effective Time, (y) any of the conditions to the Merger set forth in Article IX not being satisfied or (z) a material violation of any provision of this Agreement or the Bank Merger Agreement, except, in each case, as may be required by applicable law or regulation; or

(d) agree to do any of the foregoing.

7.11 Access to Properties and Records. In order to facilitate the consummation of the Merger and the Bank Merger and the integration of the business and operations of the parties, subject to Section 12.1 hereof and subject to applicable laws relating to exchange of information, NewAlliance shall permit CBI and its officers, employees, counsel, accountants and other authorized representatives, access, upon reasonable notice, to its personnel and properties and those of the NewAlliance Subsidiaries, and shall disclose and

make available to CBI during normal business hours throughout the period prior to the Effective Time all of the books, papers and records of NewAlliance or any NewAlliance Subsidiary relating to the assets, properties, operations, obligations and liabilities, including, but not limited to, all books of account (including the general ledger), tax records, minute books of directors’ (other than minutes that discuss any of the transactions contemplated by this Agreement or other strategic alternatives) and shareholders’ meetings, organizational documents, Bylaws, material contracts and agreements, filings with any regulatory authority, litigation files, plans affecting employees, and any other business activities or prospects in which CBI may have a reasonable interest; provided, however, that NewAlliance shall not be required to take any action that would provide access to or to disclose information where such access or disclosure would violate or prejudice the rights or business interests or confidences of any customer or other person or would result in the waiver by it of the privilege protecting communications between it and any of its counsel. In addition, NewAlliance and the NewAlliance subsidiaries shall not be required to disclose any analysis, minutes, or other materials pertaining to the financial or other evaluation or discussion of (i) this Agreement, or the transactions contemplated hereunder, or (ii) any third party proposal to acquire a controlling interest in NewAlliance. NewAlliance shall provide and shall request its auditors to provide CBI with such historical financial information regarding NewAlliance and any NewAlliance Subsidiary (and related audit reports and consents) as CBI may reasonably request for securities disclosure purposes. CBI shall use reasonable efforts to minimize any interference with NewAlliance’s and any NewAlliance Subsidiary’s regular business operations during any such access to NewAlliance’s or any NewAlliance Subsidiary’s personnel, property, books or records. NewAlliance and its Subsidiaries shall permit CBI, at CBI’s expense, to cause so-called “Phase I Environmental Site Assessments” and/or “Phase II Environmental Site Assessments” to be performed at any physical location owned or operated by NewAlliance or any NewAlliance Subsidiary and, to the extent NewAlliance or the applicable NewAlliance Subsidiary has the contractual right to do so, at any Loan Property or Participation Facility. CBI agrees to indemnify and hold harmless, NewAlliance, each NewAlliance Subsidiary, and any landlord or other persons with an interest in the real property, from and against any damages, claims, losses or expenses of any kind, including reasonable attorneys fees, pertaining to or arising from any entry onto, or any assessments or other studies undertaken by CBI with respect to, any such real property under this Section.

NewAlliance shall provide CBI and its counsel with appropriate opportunity to review and comment on the Merger Registration Statement and Proxy Statement-Prospectus prior to the time they are initially filed with the SEC or any amendments are filed with the SEC.

NewAlliance shall provide CBI and its counsel with appropriate opportunity to review and comment on all amendments and supplements to the Merger Registration Statement and Proxy Statement-Prospectus and all responses to requests for additional information and replies to comments prior to their being filed with, or sent to, the SEC. Each of NewAlliance and CBI agrees to use all reasonable efforts, after consultation with the other party hereto, to respond promptly to all such comments of and requests by the SEC and to cause the Proxy Statement-Prospectus and all required amendments and supplements thereto to be mailed to the holders of CBI Common Stock entitled to vote at the CBI Stockholders Meeting referred to in Section 8.1 hereof at the earliest practicable time.

8.2.3 CBI and NewAlliance shall promptly notify the other party if at any time it becomes aware that the Proxy Statement-Prospectus or the Merger Registration Statement contain any untrue statement of a material fact or omit to state a material fact required to be stated therein or necessary to make the statements contained therein, in light of the circumstances under which they were made, not misleading. In such event, CBI shall cooperate with NewAlliance in the preparation of a supplement or amendment to such Proxy Statement-Prospectus which corrects such misstatement or omission, and NewAlliance shall file an amended Merger Registration Statement with the SEC, and CBI shall mail an amended Proxy Statement-Prospectus to CBI’s stockholders. CBI, on the one hand, and NewAlliance on the other shall each provide to the other a “comfort” letter from its independent certified public accountant, dated as of the date of the Proxy Statement-Prospectus and updated as of the Effective Date of the Merger, with respect to certain financial information regarding CBI and NewAlliance in the Proxy Statement-Prospectus, respectively, each in form and substance which is customary in transactions such as the Merger, unless waived by the Parties.

8.3 Regulatory Approvals. Each of CBI, Cornerstone and NewAlliance will cooperate with the other and use all reasonable efforts to promptly prepare all necessary documentation, to effect all necessary filings and to obtain all necessary permits, consents, approvals and authorizations of all third parties and governmental bodies necessary to consummate the transactions contemplated by this Agreement, including without limitation the Merger and the Bank Merger. CBI and NewAlliance will furnish each other and each other’s counsel with all information concerning themselves, their subsidiaries, directors, officers and shareholders and such other matters as may be necessary or advisable in connection with the Proxy Statement-Prospectus and any application, petition or any other statement or application made by or on behalf of NewAlliance, NAB, CBI or Cornerstone to any governmental body in connection with the Merger, the Bank Merger, and the other transactions contemplated by this Agreement. Each party hereto shall have the right to review and approve in advance all characterizations of the information relating to such party and any of its Subsidiaries that appear in any filing made in connection with the transactions contemplated by this Agreement with any governmental body. In addition, NewAlliance, NAB, CBI and Cornerstone shall each furnish to the other for review a copy of each such filing made in connection with the transactions contemplated by this Agreement with any governmental body prior to its filing.

8.4 Affiliates. CBI shall use all reasonable efforts to cause each director, executive officer and other person who is an “affiliate” (for purposes of Rule 145 under the Securities Act) of CBI to deliver to NewAlliance, as soon as practicable after the date of this Agreement and in no event later than thirty (30) days after the date this Agreement, a written agreement, in the form of Exhibit E hereto, providing that such person will not sell, pledge, transfer or otherwise dispose of any shares of NewAlliance Common Stock to be received by such “affiliate,” as a result of the Merger except in compliance with the applicable provisions of the Securities Act and the rules and regulations thereunder.

8.5 Compliance with Anti-Trust Laws. Each of NewAlliance and CBI shall use reasonable best efforts in good faith to resolve objections, if any, which may be asserted with respect to the Merger under anti-trust laws. In the event a suit is threatened or instituted challenging the Merger as violative of anti-trust laws, each of NewAlliance and CBI shall use reasonable best efforts in good faith to avoid the filing of, or resist or resolve such suit. NewAlliance and CBI shall use reasonable best efforts in good faith to take such action as may

be required: (a) by the FRB, the Connecticut Banking Commissioner, and the Antitrust Division of the DOJ or the United States Federal Trade Commission in order to resolve such objections as any of them may have to the Merger under antitrust laws, or (b) by any federal or state court of the United States, in any suit brought by a private party or Governmental Entity challenging the Merger as violative of antitrust laws, in order to avoid the entry of, or to effect the dissolution of, any injunction, temporary restraining order, or other order which has the effect of preventing the consummation of the Merger. Reasonable best efforts in good faith shall not include, among other things and only to the extent NewAlliance so desires, the willingness of NewAlliance to accept an order agreeing to the divestiture, or the holding separate, of any assets of NewAlliance or CBI.

8.6 Execution of Bank Merger Agreement. Contemporaneously with the execution of this Agreement, Cornerstone and NAB each shall execute and deliver the Bank Merger Agreement, substantially in the form attached hereto as Exhibit A.

11.1.1 By the mutual written agreement of NewAlliance and CBI;

11.1.2 By either NewAlliance or CBI, 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 material breach of any of the representations or warranties set forth in this Agreement on the part of the other party, which breach (i) by its nature cannot be cured, or (ii) shall not have been cured within thirty (30) days after written notice by the non-breaching party to the breaching party, provided that, in the event the breach cannot reasonably be cured within the specified thirty (30) day period, the time to cure shall be extended to such time as reasonably may be necessary to effect the cure, not to exceed an additional thirty (30) days (sixty (60) days in the aggregate), conditioned upon the breaching party commencing to cure the breach within fifteen (15) days after notice of the breach, providing written notice to the non-breaching party within such fifteen (15) day period of the breaching party’s inability to complete the cure within the specified thirty (30) day period and thereafter diligently and continuously prosecuting the cure to completion. For purposes of this Section 11.1.2, a material breach shall be deemed to be a breach which has, either individually or in the aggregate, a Material Adverse Effect on (x) the party making such representations or warranties or (y) the consummation of the Merger, the Bank Merger, and the other transactions contemplated hereby, provided, that if the applicable representation or warranty by its terms already is limited to a Material Adverse Effect, this provision shall not be deemed to further limit or qualify the representation or warranty;

11.1.3 By either NewAlliance or CBI, 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 material failure to perform or comply with any of the covenants or agreements set forth in this Agreement on the part of the other party, including also any failure to satisfy a condition to Closing, which failure (i) by its nature cannot be cured, or (ii) shall not have been cured within thirty (30) days after written notice by the non-breaching party to the breaching party, provided that, in the event the breach cannot reasonably be cured within the specified thirty (30) day period, the time to cure shall be extended to such time as reasonably may be necessary to effect the cure, not to exceed an additional thirty (30) days (sixty (60) days in the aggregate), conditioned upon the breaching party commencing to cure the breach within fifteen (15) days after notice of the breach, providing written notice to the non-breaching party within such fifteen (15) day period of the breaching party’s inability to complete the cure within the specified thirty (30) day period and thereafter diligently and continuously prosecuting the cure to completion.

11.1.6 By either NewAlliance or CBI if (i) final action has been taken by a Governmental Entity whose approval is required in connection with this Agreement or the Bank Merger Agreement and the transactions contemplated hereby or thereby, which final action (x) has become non-appealable and (y) does not approve this Agreement or the Bank Merger Agreement or the transactions contemplated hereby or thereby, (ii) any regulatory authority whose approval or non-objection is required in connection with this Agreement or the Bank Merger Agreement and the transactions contemplated hereby or thereby, has stated in writing that it will not issue the required approval or non-objection, or (iii) any court of competent jurisdiction or other governmental authority shall have issued an order, decree, ruling or taken any other action restraining, enjoining or otherwise prohibiting the Merger or the Bank Merger and such order, decree, ruling or other action shall have become final and non-appealable, any of the foregoing being termed an “Adverse Action”, provided that each party shall use their respective reasonable best efforts to obtain all necessary approvals from any applicable Governmental Entity and to timely and fully address any objections raised or questions posed by such Governmental Entity;

11.1.7 By NewAlliance if at any time prior to the CBI Shareholder meeting, (a) CBI shall have breached Section 6.10 of this Agreement, (b) the CBI Board of Directors shall have failed for any reason to make its recommendation referred to in Section 8.1, withdrawn such recommendation or modified or changed such recommendation in a manner adverse in any respect to the interests of NewAlliance or (c) CBI shall have materially breached its obligations under Section 8.1 by failing to call, give notice of, convene and hold the CBI Shareholders Meeting in accordance with Section 8.1.

11.1.8 By NewAlliance if a tender offer or exchange offer for 25% or more of the outstanding shares of CBI Common Stock is commenced (other than by NewAlliance), and the CBI Board of Directors recommends that the shareholders of CBI tender their shares in such tender or exchange offer or otherwise fails to recommend that such shareholders reject such tender offer or exchange offer within the ten-Business Day period specified in Rule 14e-2(a) under the Exchange Act.

11.1.9 At any time prior to the CBI Shareholders Meeting, by CBI in order to concurrently enter into an acquisition agreement or similar agreement (each, an “Acquisition Agreement”) with respect to a Superior Proposal which has been received and considered by CBI and the CBI Board of Directors in compliance with Section 6.10 hereof, provided, however, that this Agreement may be terminated by CBI pursuant to this Section 11.1.9 only after the fifth (5^th) Business Day following NewAlliance’s receipt of written notice from CBI advising NewAlliance that CBI is prepared to enter into an Acquisition Agreement with respect to a Superior Proposal, and only if, during such five (5)-Business Day period, NewAlliance does not, in its sole discretion, make an offer to CBI that CBI’s Board of Directors determines in good faith, after consultation with its financial and legal advisors, is at least as favorable as the Superior Proposal.

11.1.10 By CBI, if the Board of Directors of CBI so determines by the vote of a majority of all of its members, by giving written notice to NewAlliance not later than the end of the second Business Day next following the Determination Date, in the event that, as of the Determination Date, both of the following conditions are satisfied:

(i) the Average Closing Price shall be less than 85% of the NewAlliance Starting Price; and

(ii) (A) the number obtained by dividing the Average Closing Price by the NewAlliance Starting Price (the “NewAlliance Ratio”) is less than (B) the number obtained by dividing the Final Index Price by the Initial Index Price and subtracting 0.15 from such quotient (the “Index Ratio”).

If CBI elects to exercise its termination right pursuant to this Section 11.1.10, it shall give written notice to NewAlliance. During the five Business Day period commencing with its receipt of such notice, NewAlliance may, at its option (the “Fill Option”), adjust the Stock Election Price to equal the lesser of (i) a number equal to a quotient (rounded to the nearest one-ten-thousandth), the numerator of which is the product of 0.85, the NewAlliance Starting Price and the Stock Election Price (as then in effect) and the denominator of which is the Average Closing Price, and (ii) a number equal to a quotient (rounded to the nearest one-ten-thousandth), the numerator of which is the Index Ratio multiplied by the Stock Election Price and the denominator of which is the NewAlliance Ratio. If NewAlliance makes an election contemplated by the preceding sentence within such five (5) Business Day period, it shall give written notice to CBI of such election and the revised Stock Election Price, whereupon no termination shall have occurred pursuant to this Section 11.1.10 and this Agreement shall remain in effect in accordance with its terms (except as the Stock Election Price shall have been so modified), and any references in this Agreement to the “Stock Election Price” shall thereafter be deemed to refer to the Stock Election Price as adjusted pursuant to this Section 11.1.10. If the outstanding shares of common stock of NewAlliance or any company belonging to the Index Group shall be changed into a different number of shares by reason of any stock dividend, reclassification, recapitalization, split-up, combination, exchange of shares or similar transaction between the date of this Agreement and the Determination Date, the prices for the common stock of such company will be appropriately adjusted.

11.2 Effect of Termination.

11.2.1 In the event of termination of this Agreement pursuant to any provision of Section 11.1, this Agreement shall forthwith become void and have no further force, except that the provisions of Sections 11.1, 11.3, 12.1, 12.2, 12.6, 12.9, 12.10, this Section 11.2, and any other Section which, by its terms, relates to post-termination rights or obligations, shall survive such termination of this Agreement and remain in full force and effect.

(i) $2.0 million if CBI has terminated this Agreement pursuant to the provisions of Sections 11.1.2 or 11.1.3 hereof before December 30, 2005, and

(ii) $4.0 million if CBI has terminated this Agreement pursuant to the provisions of Sections 11.1.2 or 11.1.3 on or after December 30, 2005; provided, however, that $2.0 million of the NewAlliance Termination Fee required to be paid pursuant to this Section 11.2.3(a)(ii) shall be repaid to NewAlliance in the event CBI enters into an acquisition agreement with respect to, or recommends acceptance of, an Acquisition Proposal within two (2) years of the date CBI has terminated this Agreement pursuant to this subsection. The repayment of the $2.0 million by CBI to NewAlliance shall be in the manner and subject to the conditions set forth in 11.2.3(b)(ii).

(b)(i) In the event the NewAlliance Termination Fee shall become payable to CBI pursuant to 11.2.3(a)(i) or (ii) hereof, NewAlliance shall pay to CBI the NewAlliance Termination Fee on or before the third Business Day following the date of termination of this Agreement.

The repayment shall be made by wire transfer of immediately available funds to an account designated by NewAlliance.

11.2.4 CBI and NewAlliance agree that the agreements contained in Sections 11.2.2 and 11.2.3 are an integral part of the transactions contemplated by this Agreement, that without such agreement neither party would have entered into this Agreement and that such amounts do not constitute a penalty or liquidated damages in the event of a breach of this Agreement by either party. If either party fails to pay the amounts due under Section 11.2.2 or 11.2.3, as applicable, above within the time periods specified therein, the delinquent payor shall pay the costs and expenses (including reasonable legal fees and expenses) incurred by the other in connection with any action in which the party entitled to payment prevails, including the filing of any lawsuit taken to collect payment of such amounts, together with interest on the amount of any such unpaid amounts at the prime lending rate prevailing during such period as published in The Wall Street Journal, calculated on a daily basis from the date such amounts were required to be paid until the date of actual payment.

11.3 Amendment, Extension and Waiver. Subject to applicable law, at any time prior to the Effective Time (whether before or after approval thereof by the shareholders of CBI), the parties hereto by action of their respective Boards of Directors, may (a) amend this Agreement, (b) extend the time for the performance of any of the obligations or other acts of any other party hereto, (c) waive any inaccuracies in the representations and warranties contained herein or in any document delivered pursuant hereto, or (d) waive compliance with any of the agreements or conditions contained herein; provided, however, that after any approval of this Agreement and the transactions contemplated hereby by the shareholders of CBI, there may not be, without further approval of such shareholders, any amendment of this Agreement which reduces the amount, value or changes the form of consideration to be delivered to CBI’s shareholders or Option holders pursuant to this Agreement. This Agreement may not be amended except by an instrument in writing signed on behalf of each of the parties hereto. Any agreement on the part of a party hereto to any extension or waiver shall be valid only if set forth in an instrument in writing signed on behalf of such party, but such waiver or failure to insist on strict compliance with such obligation, covenant, agreement or condition shall not operate as a waiver of, or estoppel with respect to, any subsequent or other failure.
