MERGER CONSIDERATION; EXCHANGE PROCEDURES

Section 3.1 Merger Consideration.

(a) Subject to the terms and conditions of this Agreement, each share of Bank Common Stock that is outstanding immediately prior to the Effective Time (excluding any Dissenting Shares and any shares of Bank Common Stock cancelled pursuant to Section 3.1(b)) shall be converted into and become the right to receive cash and/or shares of Sterling Common Stock as set forth in this Article III which, together with the consideration provided for in Section 4.5 hereinbelow with respect to fractional shares, is referred to herein as the “Merger Consideration.”

(b) Each share of Bank Common Stock held in the treasury of the Bank and each share of Bank Common Stock owned by Sterling or any direct or indirect wholly owned Subsidiary of Sterling or the Bank immediately prior to the Effective Time shall be canceled without any conversion and no payment or distribution shall be made with respect thereto.

-9-

(c) Each of the shares of Sterling Common Stock issued and outstanding immediately before the Effective Time shall continue to be issued and outstanding as one share of common stock of Sterling. Each of the shares of the capital stock of Merger Sub issued and outstanding immediately before the Effective Time shall remain outstanding, shall be unaffected by the Merger, and shall constitute the only outstanding shares of capital stock of the Surviving Bank.

(d) Notwithstanding any other provision of this Agreement, each holder of shares of Bank Common Stock exchanged pursuant to the Merger, who would otherwise have been entitled to receive a fraction of a share of Sterling Common Stock (after taking into account all certificates delivered by such holder) shall receive, in lieu thereof, cash (without interest) in accordance with Section 4.5 hereof. No such holder will be entitled to dividends, voting rights or other rights as a shareholder in respect of any fractional share.

(e) Notwithstanding anything in this Agreement to the contrary, no share of Bank Common Stock, the holder of which shall have complied with §32.303 of the TFC, and the provisions of Article 5.12 of the TBCA as to appraisal rights (a “Dissenting Share”), shall be deemed converted into and to represent the right to receive the Merger Consideration hereunder, and the holders of Dissenting Shares, if any, shall be entitled to payment, solely from the Surviving Bank, of the appraised value of such Dissenting Shares to the extent permitted by and in accordance with the provisions of Article 5.12 of the TBCA; provided, however, that (i) if any holder of Dissenting Shares shall, under the circumstances permitted by the TBCA, subsequently deliver a written withdrawal of his or her demand for appraisal of such Dissenting Shares, (ii) if any holder fails to establish his or her entitlement to rights to payment as provided in such Article 5.12, or (iii) if neither any holder of Dissenting Shares nor the Surviving Bank has filed a petition demanding a determination of the value of all Dissenting Shares within the time provided in such Article 5.12, such holder or holders (as the case may be) shall forfeit such right to payment for such Dissenting Shares pursuant to such Article 5.12 and each such Dissenting Share shall thereupon be converted into and shall represent the right to receive the Merger Consideration therefore. The Bank shall give Sterling (i) prompt notice of any written objections to the Merger submitted to the Bank in accordance with Article 5.12, any attempted withdrawals of such objections, and any other instruments served pursuant to applicable law received by the Bank relating to shareholders’ rights of appraisal and (ii) the opportunity to direct all negotiations and proceedings with respect to demands for appraisal under the TFC and the TBCA. The Bank shall not, except with the prior written consent of Sterling, voluntarily make any payment with respect to any demands for appraisals of Bank Common Stock, offer to settle or settle any such demands or approve any withdrawal of any such demands.

(a) Subject to the terms and conditions of this Agreement, the aggregate consideration payable by Sterling in exchange for all shares of Bank Common Stock issued and outstanding immediately prior to the Effective Time (excluding any Dissenting Shares and any shares of Bank Common Stock cancelled pursuant to Section 3.1(b)) shall be $52,000,000 (the “Aggregate Merger Consideration”). Each share of Bank Common Stock issued and outstanding as of the Effective Time (excluding shares to be canceled pursuant to Section 3.1(b) and Dissenting Shares) will be converted into the right to receive:

(i) the number of shares of Sterling Common Stock that is equal to $26,520,000 divided by the Average Closing Price, then further divided by the Bank Shares Number; and

-10-

(ii) the amount in cash that is equal to $25,480,000 divided by the Bank Shares Number (the “Per Share Cash Consideration”).

(b) The number of shares of Sterling Common Stock to be exchanged for each share of Bank Common Stock shall be adjusted appropriately to reflect any stock dividend reclassification, split-up, combination, exchange of shares or similar transaction with respect to Sterling Common Stock between the Starting Date and the Closing Date.

(c) Notwithstanding any adjustment to the Sterling Common Stock pursuant to Section 3.2(b), in no event shall the aggregate Per Share Cash Consideration exceed 49% of the Aggregate Merger Consideration.

Section 3.3 Bank Stock Options and Warrants.

(a) Prior to the Closing Date, the Bank shall (i) cause each unexpired and unexercised option or warrant of the Bank (collectively, the “Bank Options”) to either be (a) exercised and fully paid and converted into shares of Bank Common Stock, or (b) terminated, and (ii) cause the Bank Stock Plans to be terminated. The Bank shall not permit any holder of the Bank Options to exercise such Bank Option by any means other than the payment of the exercise price thereof in cash, unless the Bank is contractually obligated to do so. With respect to any such holder, the Bank shall use its best efforts to encourage such holder to exercise such Bank Option by payment in cash. A list of the Bank Options and the holders thereof is set forth in Section 5.2 of the Bank Disclosure Schedule.

(b) The Bank shall take all actions necessary or reasonably requested by Sterling to ensure that following the Effective Time, no holder of any Bank Option will have any right thereunder to acquire any equity securities of the Bank, Sterling or any of their respective Subsidiaries or any right to payment in respect of any such securities of the Bank, except for payment of the Merger Consideration with respect to the shares of Bank Common Stock into which such Bank Options are converted prior to the Effective Time.

As of the Effective Time, Sterling shall deposit with a bank or trust company designated by Sterling and reasonably acceptable to the Bank for the benefit of the holders of shares of Bank Common Stock (the “Exchange Agent”), for exchange in accordance with this Article IV, (i) certificates representing shares of Sterling Common Stock, and (ii) cash, each in a number or an amount sufficient to make all payments of the Merger Consideration pursuant to Article III. Such shares of Sterling Common Stock and cash, together with any dividends or distributions with respect thereto paid in respect of a record date after the Effective Time, being hereinafter referred to as the “Exchange Fund”. The Exchange Agent

-11-

shall, pursuant to irrevocable instructions from Sterling, deliver the Merger Consideration contemplated to be issued pursuant hereto out of the Exchange Fund. The Exchange Fund shall not be used for any other purpose.

Section 4.2 Exchange Procedures. Promptly after the Effective Time, the Exchange Agent shall mail to each holder of record of a certificate or certificates which, immediately prior to the Effective Time, represented outstanding shares of Bank Common Stock (the “Certificates”), other than shares canceled in accordance with Section 3.1(b): (i) a letter of transmittal (which shall specify that delivery shall be effected, and risk of loss and title to the Certificates theretofore representing shares of Bank Common Stock shall pass, only upon proper delivery of such Certificates to the Exchange Agent, and shall be in such form and have such other provisions as Sterling shall specify) and (ii) instructions for use in effecting the surrender of the Certificates in exchange for the Merger Consideration. Upon surrender of a Certificate for cancellation to the Exchange Agent (or to such other agent or agents as may be appointed by Sterling), together with such letter of transmittal, duly executed, and any other required documents, the holder of such Certificate shall be entitled to receive in exchange therefor (i) shares of Sterling Common Stock representing, in the aggregate, the whole number of shares that such holder has the right to receive pursuant to Section 3.2, (ii) a check in the amount equal to the cash portion of the Merger Consideration that such holder has the right to receive pursuant to Section 3.2, and (iii) a check in the amount equal to the cash, if any, that such holder has the right to receive in lieu of any fractional shares of Sterling Common Stock pursuant to Section 3.1(d) and Section 4.5, and the Certificates so surrendered shall forthwith be cancelled. No interest will be paid or will accrue on any cash payable pursuant to the provisions of Article III or this Section 4.2. In the event of a transfer of ownership of Bank Common Stock that is not registered in the transfer records of the Bank, one or more certificates of Sterling Common Stock evidencing, in the aggregate, the proper number of shares of Sterling Common Stock pursuant to Section 3.2, a check in the proper amount of the cash portion of the Merger Consideration pursuant to Section 3.2 and a check in the proper amount of cash in lieu of any fractional shares of Sterling Common Stock pursuant to Section 3.1(d) and Section 4.5, may be issued to a transferee if the Certificate representing such Bank Common Stock is presented to the Exchange Agent accompanied by all documents required to evidence and effect such transfer and by evidence that any applicable stock transfer taxes have been paid. Until surrendered as contemplated by this Section 4.2, each Certificate shall be deemed at any time after the Effective Time to represent only the right to receive upon such surrender Merger Consideration as provided in Article III and cash in lieu of any fractional shares of Sterling Common Stock as contemplated by Section 3.1(d) and Section 4.5. The Certificates for Bank Common Stock so surrendered shall be duly endorsed as the Exchange Agent may require. Sterling shall not be obligated to deliver the consideration to which any former holder of Bank Common Stock is entitled as a result of the Merger until such holder surrenders his or her Certificates formerly representing shares of Bank Common Stock for exchange as provided in this Article IV. In addition, Certificates surrendered for exchange by any person constituting an “affiliate” of the Bank for purposes of Rule 145(c) under the Securities Act shall not be exchanged for certificates representing whole shares of Sterling Common Stock until Sterling has received a written agreement from such person as provided in Section 8.8.

-12-

Section 4.3 Voting and Dividends. Former shareholders of record of the Bank who are to receive shares of Sterling Common Stock pursuant to Section 3.2 shall be entitled to vote after the Effective Time at any meeting of Sterling shareholders the number of whole shares of Sterling Common Stock into which their respective shares of Bank Common Stock are converted, regardless of whether such holders have exchanged their Certificates representing Bank Common Stock for certificates representing Sterling Common Stock in accordance with the provisions of this Agreement. Until surrendered for exchange in accordance with the provisions of Section 4.2, each Certificate theretofore representing shares of the Bank Common Stock (other than shares to be canceled pursuant to Section 3.1) shall from and after the Effective Time represent for all purposes only the right to receive the Merger Consideration, as set forth in this Agreement. Former shareholders of record of the Bank who are to receive shares of Sterling Common Stock pursuant to Section 3.2 shall be entitled to any dividends paid to holders of record of Sterling Common Stock after the Effective Time, provided that no dividend or other distribution payable to the holders of record of Sterling Common Stock, at or as of any time after the Effective Time, shall be paid to the holder of any Certificate representing shares of Bank Common Stock issued and outstanding at the Effective Time until such holder physically surrenders such Certificate for exchange as provided in Section 4.2, promptly after which time all such dividends or distributions shall be paid (without interest).

Section 4.4 No Further Ownership Rights in Bank Common Stock. All shares of Sterling Common Stock and/or cash issued upon the surrender for exchange of shares of Bank Common Stock in accordance with the terms hereof (including any cash paid in lieu of fractional shares of Sterling Common Stock pursuant to Section 3.1(d) and Section 4.5) shall be deemed to have been issued in full satisfaction of all rights pertaining to such shares of Bank Common Stock, and after the Effective Time there shall be no further registration of transfers on the stock transfer books of the Surviving Bank of the shares of Bank Common Stock that were outstanding immediately prior to the Effective Time. If, after the Effective Time, Certificates are presented to the Surviving Bank for any reason, they shall be canceled and exchanged as provided in this Article IV.

Section 4.5 No Fractional Shares. No certificates or scrip representing fractional shares of Sterling Common Stock shall be issued upon the surrender for exchange of Certificates for Bank Common Stock pursuant to this Article IV, and no dividend or other distribution, stock split or interest shall relate to any such fractional share, and such fractional interests shall not entitle the owner thereof to any voting or other rights of a security holder of Sterling. In lieu of any fractional share, each holder of shares of Bank Common Stock who would otherwise have been entitled to a fraction of a share of Sterling Common Stock upon surrender of the Certificates for such Bank Common Stock for exchange pursuant to this Article IV will be paid an amount in cash (without interest) equal to the product of (i) such fractional part of a share of Sterling Common Stock multiplied by (ii) the Average Closing Price.

Section 4.6 Termination of Exchange Fund. Any portion of the Exchange Fund that remains undistributed to the former shareholders of the Bank for six months after the Effective Time shall be delivered to Sterling upon demand, and any shareholders of the Bank who have not theretofore complied with this Article IV shall thereafter look only to Sterling for payment of their claim for the Merger Consideration.

Section 4.7 Escheat of Exchange Fund. None of Sterling, Merger Sub, the Bank, or the Exchange Agent shall be liable to any person in respect of any Merger Consideration from the Exchange Fund delivered to a public office pursuant to any applicable abandoned property, escheat or similar law. If any Certificates representing shares of Bank Common Stock shall not have been surrendered immediately prior to the date on which any Merger Consideration in respect of such Certificate would otherwise escheat to or become the property of any government authority, any such Merger Consideration in respect of such Certificate shall, at such time and to the extent permitted by applicable law, become the property of the Surviving Bank, free and clear of all claims or interest of any Person previously entitled thereto.

Section 4.8 Lost Certificates. If any Certificates shall have been lost, stolen or destroyed, then 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 Sterling or the Exchange Agent, the posting by such Person of a bond in such reasonable amount as Sterling or the Exchange Agent may direct as indemnity against any claim that may be made against the Surviving Bank with respect to such Certificate, the Exchange Agent will pay in exchange for such lost, stolen or destroyed Certificate the Merger Consideration to be paid in respect of the shares of Bank Common Stock represented by such Certificate, as contemplated by this Agreement.

The Bank has set forth in Section 5.12 of the Bank Disclosure Schedule (i) a list of all of the Bank Benefit Plans, (ii) a list of the Bank Benefit Plans that are Bank Stock Plans and (iii) a list of the number of shares covered by, exercise prices for, and holders of, all stock options granted and available for grant under Bank Benefit Plans.

(b) From their inception, all Bank Benefit Plans have been and are in compliance in all material respects with the applicable terms of ERISA and the Code and any other applicable laws, rules and regulations, including the terms of such plans. Section 5.12 of the Bank Disclosure Schedule identifies each of the Bank Benefit Plans which purports to satisfy the requirements of Section 401(a) of the Code (a “Qualified Plan”). A copy of each Qualified Plan and of the most recent determination letter from the Internal Revenue Service with respect to each of the Qualified Plans has been provided to Sterling. All of such determination letters remain in effect and have not been revoked. No Qualified Plan has been amended since the issuance of the most recent determination letter. Each Qualified Plan has been administered according to its terms, except for those terms which are inconsistent with the changes required by the Code and any regulations and rulings promulgated thereunder for which changes are not yet required to be made, in which case each Qualified Plan has been administered in accordance with the provisions of the Code and such regulations and rulings, and neither the Bank nor any member of the Bank Controlled Group has taken any action which could adversely affect the qualified status of any Qualified Plan or any related trust.

(c) All liabilities of any sort (contingent or otherwise) under any Bank Benefit Plan are fully accrued or reserved against in the Bank Financial Statements in accordance with GAAP. No Bank Benefit Plan is or has ever been subject to Title IV of ERISA or Section 412 of the Code.

-22-

(d) Neither the Bank nor any of its Subsidiaries has any obligations for retiree health or other welfare benefits under any Bank Benefit Plan or otherwise other than as required by COBRA or other applicable law. There are no restrictions on the rights of the Bank or its Subsidiaries to unilaterally amend or terminate any such Bank Benefit Plan at any time without incurring any material liability thereunder.

(e) Except as disclosed in Section 5.12 of the Bank Disclosure Schedule, neither the execution and delivery of this Agreement nor the consummation of the transactions contemplated hereby will (i) result in any payment (including, without limitation, severance, golden parachute or otherwise) becoming due to any person under any Bank Benefit Plan or otherwise, (ii) increase any benefits otherwise payable under any Bank Benefit Plan or (iii) result in any acceleration of the time of payment or vesting of any such benefits. No amounts payable under any Bank Benefit Plan will be nondeductible pursuant to either Section 280G or 162(m) of the Code (or any corresponding provision of state, local or foreign tax law).

(f) None of the Bank, any Subsidiary, or any plan fiduciary of any Bank Benefit Plan has knowingly engaged in any transaction in violation of Section 406 of ERISA (for which transaction no exemption exists under Section 408 of ERISA) or in any “prohibited transaction” as defined in Section 4975(c)(1) of the Code (for which no exemption exists under Section 4975(c)(2) or 4975(d) of the Code).

(g) All Bank Benefit Plans, related trust agreements or annuity contracts (or any other funding instruments), are legally valid and binding and in full force and effect and there are no written agreements or, to the Bank’s knowledge, any oral agreements, regarding increases in benefits (whether expressed or implied) under any of these plans, nor, to the Bank’s knowledge, any obligations, commitments, or understanding to continue any of these plans (whether expressed or implied) except as required by Section 4980B of the Code and Sections 601-608 of ERISA.

(h) There are no known violations, defaults, breaches or liabilities under any Bank Benefit Plan which could subject the Bank, any of its Subsidiaries, Sterling, the Bank Benefit Plan or any fiduciary thereunder, to Taxes, penalties or liabilities.

(i) There are no known claims pending with respect to, or under, any Bank Benefit Plan other than routine claims for plan benefits, and there is no litigation pending, or to the knowledge of the Bank or any Subsidiary, any disputes or litigation threatened with respect to any such plans.

(j) All “health plans” and “group health plans” (as those terms are defined by the Health Insurance Portability and Accountability Act of 1996, Public Law 104-191 (“HIPAA”)) that the Bank or any member of the Bank Controlled Group sponsors are in compliance with all applicable requirements under HIPAA. Specifically, but without limitation, all such health plans timely adopted the legally necessary policies and procedures, business associate agreements, and other required documentation to comply with privacy component of HIPAA and the regulations issued thereunder including but not limited to 45 CFR 160 and CFR Part 164 (“HIPAA Regulations”) as amended from time to time. Neither the Bank, nor any member of the Bank

-23-

Controlled Group, nor any of their respective health plans or group health plans, have known violations of any applicable requirements of HIPAA or the HIPAA Regulations.

(k) Section 5.12 of the Bank Disclosure Schedule lists each Bank Benefit Plan which provides nonqualified deferred compensation and may be subject to Section 409A of the Code, and each such plan is either exempt from Section 409A of the Code under current Internal Revenue Service guidance or has been operated in good faith compliance with Section 409A of the Code and the Internal Revenue Service guidance issued thereunder.

The Bank agrees to use its best efforts to obtain the approval and adoption of the Merger and this Agreement by the Bank’s shareholders. The Company (i) acknowledges that a breach of its covenant contained in this Section 8.3 to convene a meeting of its shareholders and call for a vote thereat with respect to the approval of this Agreement, the Merger and the transactions contemplated hereby and thereby will result in irreparable harm to Sterling which will not be compensable in monetary damages and (ii) agrees that such covenant shall be specifically enforceable and that specific performance and injunctive relief shall be a remedy properly available to Sterling for a breach of such covenant.

Section 8.4 Filing of Regulatory Approvals.

Sterling and the Bank each agree to deliver to the other copies of all non-confidential portions of any such applications.

-40-

(b) With respect to any Bank Options, the Bank shall not permit any holder of the Bank Options to exercise such Bank Option by any means other than the payment of the exercise price thereof in cash, unless the Bank is contractually obligated to do so.

(c) The Bank shall, in accordance with the terms thereof, cause all Bank Stock Plans to be terminated at and as of the Effective Time and without further action by any party.

Section 8.7 Miscellaneous Agreements and Consents. Subject to the terms and conditions of this Agreement, each of the parties hereto agrees to use its respective commercially reasonable efforts to satisfy, or cause to be satisfied, all conditions to their respective obligations under this Agreement and 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 as expeditiously as reasonably practicable, including, without limitation, using their respective commercially reasonable efforts to lift or rescind any injunction or restraining order or other order adversely affecting the ability of the parties to consummate the transactions contemplated hereby. Sterling and the Bank shall, and shall cause each of their respective Subsidiaries to, use their commercially reasonable efforts to obtain consents of all third parties and Regulatory Authorities necessary or, in the reasonable opinion of Sterling or the Bank, desirable for the consummation of the transactions contemplated by this Agreement. While this Agreement is in effect, neither Sterling nor the Bank shall take any actions, or omit to take any actions, which would cause this Agreement to become unenforceable in accordance with its terms. In case at any time after the Effective Time any further action is necessary or desirable to carry out the purposes of this Agreement, the proper officers and directors of Sterling shall be deemed to have been granted authority in the name of the Bank to take all such necessary or desirable action.

Section 8.8 Affiliates Letters. Within ten days of the execution of this Agreement, the Bank shall deliver to Sterling a letter identifying all persons who are then “affiliates” of the Bank for purposes of Rule 145 under the Securities Act. Within ten days of any person becoming an affiliate of the Bank after the Bank’s delivery of the letter referred to above, the Bank shall provide to Sterling an updated letter identifying all persons who are then “affiliates.” The Bank shall cause each person so identified to deliver to Sterling prior to the Effective Time a written agreement substantially in the form attached hereto as Annex C (an “Affiliate Letter”). For a period of not less than two years after the date hereof (or such shorter period of time as may be applicable for such “affiliates” to sell shares of Sterling Common Stock in accordance with Rule 144 of the Securities Act), Sterling will continue to file in a timely manner all securities reports required to be filed by it pursuant to Section 13 and Section 15(d) of the Exchange Act.

Section 8.9 Indemnification.

(a) Sterling shall indemnify, defend and hold harmless the directors, officers, employees, and agents of the Bank and its Subsidiaries (each, an “Indemnified Party”) against all losses, expenses (including reasonable attorneys’ fees), claims, damages or liabilities and amounts paid in settlement arising out of actions or omissions or alleged acts or omissions

-41-

occurring at or prior to the Effective Time (including the transactions contemplated by this Agreement) to the full extent permitted under the TFC, TBCA, applicable federal law or Regulatory Authorities, and by the Bank’s articles of association and bylaws as in effect on the date hereof, including provisions relating to advances of expenses incurred in the defense of any proceeding to the full extent permitted by the TFC, TBCA, applicable federal law or Regulatory Authorities, upon receipt of any undertaking required by the TFC or the TBCA, except that the right to indemnification shall not arise in those instances in which the party seeking indemnification has participated in the breach of any covenant or agreement contained herein or knowingly caused any representation or warranty of the Bank contained herein to be false or inaccurate in any respect and the claim arises principally from such breach or the falsity or inaccuracy of such representation or warranty. Without limiting the foregoing, in any case in which a determination by Sterling is required to effectuate any indemnification, Sterling shall direct, at the election of the Indemnified Party, that the determination shall be made by independent counsel mutually agreed upon between Sterling and the Indemnified Party.

(b) Notwithstanding Section 7.2, the Bank shall be permitted to purchase prior to Closing tail coverage for up to three years after the Effective Time for the Bank’s existing directors’ and officers’ liability insurance policy (provided that Sterling may substitute therefor policies of at least the same coverage and amounts containing terms and conditions which are substantially no less advantageous in the aggregate) with respect to claims arising from facts or events which occurred prior to the Effective Time and covering persons who are currently covered by such insurance; provided, however, that the Bank shall not make (and Sterling shall in no way be obligated to make) premium or other payments in respect of such coverage which exceed, for the portion related to the Bank’s directors and officers, 200% of the annual premium payments on the Bank’s current policy in effect as of the date of this Agreement (the “Maximum Amount”). If the amount of the payments necessary to maintain or procure such insurance coverage exceeds the Maximum Amount, Sterling shall use its commercially reasonable efforts to maintain the most advantageous policies of directors’ and officers’ liability insurance obtainable for a premium equal to the Maximum Amount.

(c) If Sterling shall consolidate with or merge into any other person and shall not be the continuing or surviving person of such consolidation or merger or shall transfer all or substantially all of its assets to any person, then and in each case, proper provision shall be made so that the successors and assigns of Sterling shall assume the obligations set forth in this Section 8.9.

(d) The provisions of this Section 8.9 are intended to be for the benefit of, and shall be enforceable by, each Indemnified Party, and his or her heirs and representatives.

(e) Sterling shall pay all expenses, including reasonable attorneys’ fees, that may be incurred by any Indemnified Party in successfully enforcing the indemnity and other obligations provided for in this Section 8.9 if Sterling has been finally determined to have acted in bad faith in refusing such indemnity. The Indemnified Party shall pay all expenses, including reasonable attorneys’ fees, incurred by Sterling if the indemnification or other obligations provided in this Section 8.9 are denied by a court of competent jurisdiction by final and nonappealable order.

-42-

Section 8.10 Certain Change of Control Matters. From and after the date hereof, the Bank shall take all action necessary so that none of the execution and delivery of this Agreement, the consummation of the Merger or the consummation of the other transactions contemplated hereby will either increase, or accelerate the payment of, any benefits otherwise payable under any Bank Benefit Plan other than the acceleration of the vesting of the Bank Options.

Section 8.11 Employee Benefits. As soon as possible after the Effective Time, Sterling shall provide generally to officers and employees of the Bank and its Subsidiaries employee benefits, including without limitation health and welfare benefits, life insurance and vacation arrangements, on terms and conditions which when taken as a whole are substantially similar, in the good faith opinion of Sterling, to those provided from time to time by Sterling and its Subsidiaries to their similarly situated officers and employees. In that regard, such officers and employees of the Bank shall be credited under the employee benefit plans of Sterling for their years of “eligibility service” and “vesting service” earned under the Bank Benefit Plans to the extent such Bank Benefit Plans were comparable to the applicable Sterling plans as if such service had been earned with Sterling. Such officers and employees of the Bank shall be credited with “benefit service” under the employee benefit plans of Sterling only with respect to their period of employment with Sterling and its Subsidiaries after the Effective Time in accordance with the terms and conditions of such employee benefit plans. As of the Effective Time, the employees and their dependents, if any, previously covered as of the Effective Time under the Bank’s health insurance plan shall be covered under Sterling’s health insurance plan and, to the extent possible under the terms of Sterling’s then current health insurance plan, will not be subject to any pre-existing condition limitations or exclusions, except those excluded under Sterling’s health insurance plan. The Bank’s employees shall not be required to satisfy the deductible and employee payments required by Sterling’s comprehensive medical and/or dental plans for the calendar year of the Effective Time to the extent of amounts previously credited during such calendar year under comparable plans maintained by the Bank. Nothing in this Agreement shall operate or be construed as requiring Sterling or any of its Subsidiaries to continue to maintain or to terminate any Bank Benefit Plan or any employee benefit plan of Sterling or to limit in any way Sterling’s ability to amend any such plan.

Section 8.12 Certain Actions. No party shall take any action which would adversely affect or delay the ability of either Sterling or the Bank to obtain any necessary Approvals of any Regulatory Authority or other governmental authority required for the transactions contemplated hereby or to perform its covenants and agreements under this Agreement.

Section 8.13 No Solicitation.

(a) Neither the Bank nor any of its Subsidiaries shall, nor shall it authorize or permit any of its officers, directors or employees or any investment banker, financial advisor, attorney, accountant or other representative retained by it or any of its Subsidiaries to initiate, solicit, encourage (including by way of furnishing information), or take any other action to facilitate, any inquiries or the making of any proposal which constitutes, or may reasonably be expected to lead to, any Acquisition Proposal (as defined herein), or enter into or maintain or continue discussions or negotiate with any person in furtherance of such inquiries or to obtain an Acquisition Proposal, or agree to or endorse any Acquisition Proposal, and the Bank shall notify

-43-

Sterling orally (within one Business Day) and in writing (as promptly as practicable), in reasonable detail, as to any inquiries and proposals which it or any of its Subsidiaries or any of their respective representatives or agents may receive; provided, however, that (i) the Bank may furnish or cause to be furnished confidential and non-public information concerning the Bank and its businesses, properties or assets to a third party (subject to execution by such third party of a confidentiality agreement containing confidentiality provisions substantially similar to those of the letter agreement entered into between the Bank and Sterling dated December 1, 2006), (ii) following the execution of such a confidentiality agreement, the Bank may engage in discussions or negotiations with a third party executing such an agreement, (iii) following receipt of an Acquisition Proposal, the Bank may take and disclose to its shareholders a position with respect to such Acquisition Proposal, including, if such Acquisition Proposal is a tender offer, the Bank Board may take and disclose to the Bank’s shareholders a position contemplated by Rule 14e-2 under the Exchange Act, and/or (iv) following receipt of an Acquisition Proposal, the Bank Board may withdraw or modify its recommendation referred to in Section 5.28, but in each case referred to in the foregoing clauses (i) through (iv) only to the extent that the Bank Board shall conclude in good faith (on the basis of advice from outside counsel) that such action is required in order for the Bank Board to satisfy its fiduciary obligations under applicable law; provided, further, that the Bank Board shall not take any of the foregoing actions referred to in clauses (i) through (iv) until after reasonable notice to and consultation with Sterling with respect to such action and shall continue to consult with Sterling after taking such action and, in addition, if the Bank Board receives an Acquisition Proposal or any request for confidential and non-public information or for access to the properties, books or records of the Bank or any Subsidiary for the purpose of making, or in connection with, an Acquisition Proposal, then the Bank shall promptly inform Sterling as provided above of the terms and conditions of such proposal or request and the identity of the person making it. As used herein, the term “Acquisition Proposal” means: (x) any proposal, inquiry or offer from any person relating to, or any agreement to engage in, any acquisition or purchase of a significant amount of the assets of the Bank and its Subsidiaries on a consolidated basis, or any equity interest in the Bank or any of its Subsidiaries or any take-over bid or tender offer (including an issuer bid or self-tender offer) or exchange offer, merger, plan of arrangement, reorganization, consolidation, business combination, sale of substantially all of the assets, sale of securities, recapitalization, liquidation, dissolution or similar transaction involving the Bank or any of its Subsidiaries (other than the transactions contemplated by this Agreement) or any other transaction the consummation of which would or could reasonably be expected to impede, interfere with, prevent or materially delay the consummation of the Merger or which would or could reasonably be expected to materially dilute the benefits to Sterling of the transactions contemplated hereby or (y) any public announcement of, or written communication to the Bank of, any proposal, plan or intention to do any of the foregoing. The Bank will immediately cease and cause to be terminated any existing activities, discussions or negotiations with any parties conducted heretofore with respect to any of the foregoing. “Acquisition Transaction” means the transaction(s) by which an Acquisition Proposal is consummated. Nothing in this Section 8.13 shall (a) permit the Bank to terminate this Agreement, it being understood that Section 10.1 sets forth the rights of the Bank to terminate this Agreement or (b) permit the Bank or any of its Subsidiaries to enter into any written agreement with respect to an Acquisition Proposal during the term of this Agreement (it being agreed that during the term of this Agreement neither the

-44-

Bank nor any of its Subsidiaries shall enter into any written agreement with any person that provides for, or in any way facilitates, an Acquisition Proposal, other than a confidentiality agreement in the form referred to above).

(b) Without limiting the foregoing, it is understood that any violation of the restrictions set forth in the first sentence of Section 8.13(a) by any employee, officer or director or authorized employee, agent or representative of the Bank or any of its Subsidiaries (including, without limitation, any investment banker, financial advisor, attorney or accountant or other representative retained by the Bank or any of its Subsidiaries) or otherwise shall be deemed to be a breach of Section 8.13(a) by the Bank.

Section 8.14 Termination Fee. To compensate either party for entering into this Agreement, taking actions to consummate the transactions contemplated hereunder and incurring the costs and expenses related thereto and other losses and expenses, including foregoing the pursuit of other opportunities by Sterling or the Bank, the Bank and Sterling agree as follows:

(a) Provided that Sterling is not in material breach of its obligations under this Agreement (and that such breach has not been cured promptly following receipt of written notice thereof by the Bank specifying in reasonable detail the basis of such alleged breach), the Bank shall pay to Sterling the sum of $2,500,000 (the “Termination Fee”), plus reasonable out-of-pocket expenses, including, without limitation, amounts paid or payable to banks and investment bankers, fees and expenses of counsel, accounting fees and expenses, and printing expenses, but not in excess of $50,000 (such expenses are hereinafter referred to as the “Expenses”) incurred by Sterling or any of its Affiliates in connection with or arising out of the transactions contemplated by this Agreement, regardless of when those expenses are incurred, if this Agreement is terminated (i) by the Bank under the provisions of Section 10.1(e), (ii) by either Sterling or the Bank under the provisions of Section 10.1(f) due to the failure of the Bank’s shareholders to approve and adopt this Agreement and the Merger, if at the time of such failure to so approve and adopt this Agreement and the Merger there exists an Acquisition Proposal with respect to the Bank and, within nine months of the termination of this Agreement, the Bank enters into a definitive agreement with any third party with respect to any Acquisition Proposal with respect to the Bank, or (iii) by Sterling under the provisions of Section 10.1(g).

(b) Any payment required by clauses (i) and (iii) of paragraph (a) of this Section 8.14 shall become payable within two Business Days after termination of this Agreement or, in the case of reimbursement to Sterling of the Expenses, promptly after (but in no event later than three Business Days following) Sterling’s delivery to the Bank of an itemization of Expenses. Any payment of the Termination Fee required by clause (ii) of paragraph (a) of this Section 8.14 shall become payable within two Business Days of the Bank’s entry into the definitive agreement referred to in clause (ii); provided, however, that any payment of Expenses contemplated by such clause (ii) shall be payable upon the termination of this Agreement.

(c) Provided that the Bank is not in material breach of its obligations under this Agreement (and that such breach has not been cured promptly following receipt of written notice thereof by Sterling specifying in reasonable detail the basis of such alleged breach), Sterling shall pay to the Bank the Termination Fee, plus Expenses not in excess of $50,000.00 incurred

-45-

by the Bank in connection with or arising out of the transactions contemplated by this Agreement, regardless of when those Expenses are incurred, if this Agreement is terminated by Sterling except as specifically provided in Section 10.1 hereof. Any such fee shall be payable within two Business Days after termination of this Agreement, but in the case of reimbursement of Expenses shall be payable within three Business Days following the Bank’s delivery to Sterling of an itemization of such Expenses.

(d) The Bank acknowledges that the agreements contained in this Section 8.14 are an integral part of the transactions contemplated in this Agreement, and that, without these agreements, the parties would not enter into this Agreement; accordingly, if a party fails to promptly pay the Termination Fee or Expenses when due, that party shall in addition thereto pay to the other party all costs and expenses (including fees and disbursements of counsel) incurred in collecting such Termination Fee or Expenses, as the case may be, together with interest on the amount of the Termination Fee or Expenses (or any unpaid portion thereof) from the date such payment was required to be made until the date such payment is received by such party at the prime rate as reported in The Wall Street Journal as in effect from time to time during such period.

Section 8.15 Accruals. At the request of Sterling, the Bank shall, consistent with GAAP, immediately prior to the Closing establish and take such reserves and accruals as Sterling shall reasonably request to conform the Bank’s loan, accrual and reserve policies and practices to the policies of Merger Sub; provided, however, that no such adjustment shall constitute or be deemed to be a breach, violation or failure to satisfy any representation, warranty, covenant, condition or other provision or constitute grounds for termination of this Agreement. No adjustment shall require any prior filing with or Approval from any Regulatory Authority or violate any law, rule or regulation applicable to the Bank or any Subsidiary.

Section 8.16 Certain Agreements. Neither the Bank nor any Subsidiary (nor any of their agents or representatives) will waive any provision of any confidentiality or standstill or similar agreement to which it is a party without the prior written consent of Sterling, unless the Bank Board or the board of directors of such Subsidiary concludes in good faith (based upon advice from outside counsel) that waiving such provision is necessary or appropriate in order for such board of directors to act in a manner which is consistent with its fiduciary obligations under applicable law. The Bank will immediately advise Sterling of the termination or waiver of any confidentiality or standstill or similar agreement to which it is a party by any party to such agreement.

Section 8.17 Release Agreements. The Bank shall use its best efforts, on behalf of Sterling and pursuant to the request of Sterling, to cause each Bank Specified Shareholder, Key Bank Official and such other Person as may be reasonably required by Sterling to execute and deliver to Sterling a written release and waiver satisfactory in form and substance to Sterling in its sole discretion and in substantially the form attached hereto as Annex D (the “Release Agreements”) prior to the Effective Time, providing for, among other things, the release of the Bank, Sterling and the Surviving Bank and their respective affiliates from any and all claims, known and unknown, that such Person has or may have against any of the foregoing through the Effective Time. The Bank agrees to provide to each person executing a Release Agreement, a form of release substantially in the form of Annex D.

Section 8.18 NASDAQ Listing. To the extent required by applicable NASDAQ rules, Sterling shall use its commercially reasonable efforts to have the shares of Sterling Common Stock to be issued to the holders of the Bank Common Stock in the Merger included for quotation on the NASDAQ prior to the Effective Time.

Section 8.19 Banker’s and Finder’s Fees. The Bank shall pay all broker’s and finder’s fees to the parties identified on Section 5.22 of the Bank Disclosure Schedule, such payments to be paid prior to the Closing Date and in such a manner so as not to constitute an expense or liability of Sterling which Sterling would be required to include in any of its consolidated statements of income.

Section 8.20 Notification; Updated Disclosure Schedule. The Bank shall give prompt notice to Sterling, and Sterling shall give prompt notice to the Bank, of (i) any representation or warranty made by it in this Agreement becoming untrue or inaccurate in any respect, including, without limitation, as a result of any change in the Bank Disclosure Schedule, or (ii) the failure by it to comply with or satisfy in any material respect any covenant, condition or agreement to be complied with or satisfied by it under this Agreement; provided, however, that no such notification shall affect the representations, warranties, covenants or agreements of the parties or the conditions to the obligations of the parties under this Agreement.

Section 8.21 Closing Date. The Bank and Sterling shall each use commercially reasonable efforts to consummate the Merger on or before April 30, 2007.

Section 8.22 Certain Tax Matters.

(a) All Tax sharing agreements or similar agreements with respect to or involving the Bank shall be terminated as of the Closing Date, and, after the Closing Date, the Bank shall not be bound thereby or have any liability thereunder.

(b) All transfer, documentary, sales, use, stamp, registration and other such Taxes and fees (including any penalties and interest) incurred in connection with this Agreement (including any corporate-level gains Tax triggered by the transactions contemplated by this Agreement), shall be paid by the Bank’s shareholders when due, and the Bank’s shareholders will, at their own expense, file all necessary Tax Returns and other documentation with respect to all such transfer, documentary, sales, use, stamp, registration and other Taxes and fees, and, if required by applicable law, Sterling will, and will cause its affiliates to, join in the execution of any such Tax Returns and other documentation.

(c) None of the parties shall take, or permit any of their Subsidiaries or Affiliates to take, any action after the Closing that would disqualify the Merger as a reorganization within the meaning of Section 368(a) of the Code.

TERMINATION

Section 10.1 Termination. Notwithstanding any other provision of this Agreement, and notwithstanding the approval of this Agreement, the Merger and the transactions contemplated hereby by the shareholders of the Bank, this Agreement may be terminated and the Merger may be abandoned at any time prior to the Effective Time:

(a) by mutual consent of the Board of Directors of Sterling and the Bank; or

(b) by the Bank Board or the Board of Directors of Sterling if (i) the Federal Reserve, the FDIC or the Commissioner has denied approval of the Merger and such denial has become final and nonappealable or has approved the Merger subject to conditions that in the judgment of Sterling would restrict it or its Subsidiaries or Affiliates in their respective spheres of operations and business activities after the Effective Time or (ii) the Effective Time does not occur by June 30, 2007; provided, however, that the right to terminate this Agreement under clause (ii) of this Section 10.1(b) shall not be available to any party whose failure to fulfill any obligation under this Agreement has been the cause of or resulted in the failure of the Effective Time to occur prior to such date; or

(c) by Sterling (if it is not in breach of any of its obligations hereunder) pursuant to notice in the event of a breach or failure by the Bank that would cause a failure of the conditions in Section 9.3, which breach or failure has not been, or cannot be, cured within 30 days after written notice of such breach is given to the Bank; or

(d) by the Bank (if it is not in breach of any of its obligations hereunder) pursuant to notice in the event of a breach or failure by Sterling that would cause a failure of the conditions in Section 9.2, which breach or failure has not been, or cannot be, cured within 30 days after written notice of such breach is given to Sterling; or

(e) by the Bank if (i) there shall not have been a breach of any covenant or agreement on the part of the Bank under this Agreement and (ii) prior to the Effective Time, the Bank shall have received a bona fide Acquisition Proposal and the Bank Board determines in its good faith judgment and in the exercise of its fiduciary duties, based as to legal matters on the written opinion of independent legal counsel and as to financial matters on the written opinion of an

-51-

investment banking firm of national reputation, that such alternative Acquisition Proposal (if consummated pursuant to its terms) would result in an alternative Acquisition Transaction that is more favorable to the Bank’s shareholders than the Merger (“Superior Proposal”) and that the failure to terminate this Agreement and accept such alternative Acquisition Proposal would be inconsistent with the proper exercise of such fiduciary duties; provided, however, that termination under this clause (ii) shall not be deemed effective until payment of the Termination Fee and Expenses required by Section 8.14; or

(f) by either Sterling or the Bank, if the Merger and this Agreement shall fail to receive the requisite vote for approval and adoption at the Bank Shareholders’ Meeting; or

(g) by Sterling if the Bank Board shall have (i) resolved to accept a Superior Proposal, or (ii) recommended to the shareholders of the Bank that they tender their shares in a tender or exchange offer commenced by a third party or (iii) withdrawn or modified, in any manner that is adverse to Sterling, its recommendation or approval of this Agreement or the Merger or recommended to the Bank’s shareholders acceptance or approval of any alternative Acquisition Proposal, or shall have resolved to do the foregoing; or

(h) by Sterling if the number of Dissenting Shares exceeds 10% of the total issued and outstanding shares (as of the Effective Time) of Bank Common Stock; or

(i) by Sterling if the factual substance of any warranties set forth in Section 5.24 is not true and accurate irrespective of the knowledge or lack of knowledge of the Bank or the disclosure of any exceptions on the Bank Disclosure Schedule, and any losses, damages, environmental response costs, liabilities, fines, penalties, costs and expenses which might arise therefrom could reasonably exceed $100,000; or

(k) by Sterling if the Average Closing Price is more than $12.91.

Section 10.3 Non-Survival of Representations, Warranties and Covenants. Except for Article III and Article IV and Section 8.1(e), Section 8.14, and Article XI, none of the respective representations, warranties, obligations, covenants and agreements of the parties shall survive the Effective Time.
