HBC shall be the surviving corporation in the Merger and shall continue its corporate existence under the laws of the State of California. HBC as the surviving corporation after the Merger, is hereinafter sometimes referred to as the “surviving corporation”.

(b) At the Effective Time, (i) the separate corporate existence of Diablo shall cease, (ii) the Articles of Incorporation and Bylaws of HBC as in effect immediately prior to the Effective Time shall be the Articles of Incorporation and Bylaws of the surviving corporation, (iii) HBC shall continue operation as a California state-chartered bank and its corporate existence under the laws of the State of California, and (iv) the name of the surviving corporation shall be “Heritage Bank of Commerce.”

(c) The directors of the surviving corporation immediately after the Merger shall be the directors of HBC immediately prior to the Merger, provided, however, that HBC shall have taken prior to the Effective Time all the necessary steps so that at the Effective Time (i) the number of directors of HBC shall be increased by two and (ii) ▇▇▇▇ ▇. Hounslow and ▇▇▇▇ ▇. ▇▇▇▇▇▇▇▇▇▇ shall be added to the HBC board of directors and serve until their successors are duly elected and qualified. The executive officers of the surviving corporation immediately after the Merger shall be the executive officers of HBC immediately prior to the Merger, provided, however, that HBC shall have taken prior to the Effective Time all the necessary steps so that at the Effective Time ▇▇▇▇▇ ▇. ▇▇▇▇▇ shall be elected as an Executive Vice President of HBC.

(d) At the Effective Time, the effect of the Merger shall be as provided in accordance with the CGCL and Financial Code as established by the California Commissioner of Financial Institutions (the "Commissioner"). Without limiting the generality of the foregoing, and subject thereto, at the Effective Time, all the property, rights, privileges, powers and franchises of Diablo shall vest in the surviving corporation, and all debts, liabilities, obligations, restrictions, disabilities and duties of Diablo shall become the debts, liabilities, obligations, restrictions, disabilities and duties of the surviving corporation.

(e) If, at any time after the Effective Time, the surviving corporation shall consider that any further assignments or assurances in law or any other acts are necessary or desirable to (i) vest, perfect or confirm, of record or otherwise, in the surviving corporation its right, title or interest in, to or under any of the rights, properties or assets of Diablo acquired or to be acquired by the surviving corporation as a result of, or in connection with, the Merger, or (ii) otherwise carry out the purposes of this Agreement, Diablo, and its proper officers and directors, shall be deemed to have granted to the surviving corporation an irrevocable power of attorney to execute and deliver all such proper deeds, assignments and assurances in law and to do all acts necessary or proper to vest, perfect or confirm title to and possession of such rights, properties or assets in the surviving corporation and otherwise to carry out the purposes of this Agreement, and the proper officers and directors of the surviving corporation are fully authorized in the name of the surviving corporation or otherwise to take any and all such action.

Section 1.2 EFFECTIVE DATE AND EFFECTIVE TIME; Closing.

(a) AS SOON AS PRACTICABLE on a date mutually agreeable to Heritage and Diablo after each of the conditions set forth in Article IX hereof have been satisfied or waived and receipt of all required corporate, regulatory, shareholder and other approvals and the expiration of any mandatory waiting or notice periods, the parties will file, or cause to be filed, with the California Secretary of State and the Commissioner, the Merger Agreement and such certificates and other documents as Heritage or HBC may deem necessary or appropriate for the Merger, which Merger Agreement and certificates and other documents shall in each case be in the form required by and executed in accordance with the applicable provisions of the CGCL and the Financial Code. The Merger shall become effective at the time the Merger Agreement and certificate of merger for such merger is filed with the California Secretary of State and the Commissioner (“Effective Time”). The date of such filings or such later effective date is herein called the “Effective Date.” The “Effective Time” of the Merger shall be the time established by the Commissioner.

(b) On a date mutually agreeable to Heritage and Diablo which is not more than five (5) Business Days after the receipt of all necessary regulatory, corporate, shareholder and other approvals and the expiration of any mandatory waiting periods, or on such other date mutually agreeable to Heritage and Diablo (herein called the “Closing Date”), a meeting (the “Closing”) will take place at the offices of Heritage in San Jose, California on the Closing Date (or at such other place to which the parties may mutually agree) at which the parties to this Agreement will exchange certificates, opinions, letters and other documents in order to determine whether all of the conditions set forth in Article IX of this Agreement have been satisfied or waived or whether any condition exists that would permit a party to this Agreement to terminate this Agreement. If no such condition then exists, or if no party elects to exercise any right it may have to terminate this Agreement, then and thereupon the appropriate parties shall execute such documents and instruments as may be necessary or appropriate in order to effect the transactions contemplated by this Agreement.

Section 1.3 ALTERNATIVE STRUCTURE. After consultation with Diablo, Heritage shall have the right, exercisable at any time prior to the Effective Time to change the method of effecting the acquisition of Diablo, if and to the extent Heritage deems such changes to be necessary, appropriate or desirable and Diablo shall take all necessary corporate and other reasonable actions to give effect to such change and shall execute, deliver and file any and all agreements and other documents necessary to effect the consummation of the transactions contemplated by such change; provided, however, that in no event shall Diablo be required to take any action set forth above or agree to any such change if such action or change could reasonably be expected to or would (x) alter or change the amount or kind of the merger consideration or the rights of or obligations to Diablo hereunder, or (y) diminish the benefits to be received by the directors, officers or employees of Diablo as set forth in this Agreement or substantially delay the delivery of the Merger Consideration, including, without limitation, any adverse effect upon the tax free treatment thereof, or (z) materially impede or delay the consummation of the Merger otherwise be materially prejudicial to the interests of the Diablo shareholders.

(d) Dissenting Common Stock. Each share of Diablo Common Stock that is a “dissenting share” within the meaning of Chapter 13 of the CGCL (“Dissenting Common Stock”) shall not be converted into or represent a right to receive Heritage Common Stock or cash hereunder unless and until such shares have lost their status as dissenting shares under Chapter 13 of the CGCL, at which time such shares shall be converted into Heritage Common Stock and cash pursuant to Section 2.5; and

(e) Cancellation of Certain Shares. Any shares of Diablo Common Stock held by Heritage or HBC or by Diablo, other than those held in a fiduciary capacity (“Treasury Shares”), shall be canceled and retired at the Effective Time and no consideration shall be issued in exchange therefor.

(a) SUBJECT TO THE OTHER PROVISIONS OF THIS ARTICLE II, each share of Diablo Common Stock issued and outstanding immediately prior to the Effective Time (other than Dissenting Common Stock and Treasury Shares) shall at the election of the holder thereof, by virtue of the Merger, be converted into the right to receive the following without interest:

(i) FOR EACH SHARE OF DIABLO COMMON STOCK WITH RESPECT TO WHICH AN ELECTION TO RECEIVE CASH HAS BEEN EFFECTIVELY MADE AND NOT REVOKED OR DEEMED REVOKED (A “Cash Election”), the right to receive in cash an amount (the “Cash Consideration”) equal to the Per Share Consideration (the “Cash Per Share Amount”) (collectively, the “Cash Election Shares”);

(ii) for each share of Diablo Common Stock with respect to which an election to receive stock has been effectively made and not revoked or deemed revoked (a “Stock Election”), the right to receive the fraction of a share of Heritage Common Stock (the “Stock Consideration”) equal to the Exchange Ratio; provided, however, that if the Average Closing Price is less than $23.50, Heritage may terminate this Agreement pursuant to Section 10.1(h) (collectively, the “Stock Election Shares”); and,

(iii) for each share of Diablo Common Stock other than shares to which a Cash Election or a Stock Election has been effectively made and not revoked (collectively, the “Non-Election Shares”), the right to receive such Stock Consideration and/or Cash Consideration as is determined in accordance with Section 2.3.

The Cash Consideration and Stock Consideration are sometimes referred to herein collectively on the “Merger Consideration.”

(b) IF, BETWEEN THE DATE HEREOF AND THE EFFECTIVE TIME, THE OUTSTANDING SHARES OF HERITAGE COMMON STOCK SHALL HAVE BEEN INCREASED, DECREASED, CHANGED INTO OR EXCHANGED FOR A DIFFERENT NUMBER OR KIND OF SHARES OR SECURITIES AS A RESULT OF A REORGANIZATION, RECAPITALIZATION, RECLASSIFICATION, STOCK DIVIDEND, STOCK SPLIT, REVERSE STOCK SPLIT, OR OTHER SIMILAR CHANGE IN CAPITALIZATION (A “Share Adjustment”), then the shares of Heritage Common Stock into which a share of Diablo Common Stock shall be converted pursuant to this Sections 2.2 shall be appropriately and proportionately adjusted so that each shareholder of Diablo shall be entitled to receive the Exchange Ratio such shareholder would have received pursuant to such Share Adjustment had the record date therefor been immediately following the Effective Time.

Section 2.3 PRORATION.

(a) NOTWITHSTANDING ANY OTHER PROVISION CONTAINED IN THIS AGREEMENT, THE NUMBER OF SHARES OF DIABLO COMMON STOCK THAT WILL BE CONVERTED INTO CASH CONSIDERATION PURSUANT TO SECTION 2.2 SHALL BE EQUAL TO THE QUOTIENT OBTAINED BY DIVIDING (X) THE TOTAL CASH CONSIDERATION, BY (Y) THE PER SHARE CONSIDERATION (WHICH, FOR THIS PURPOSE, SHALL BE DEEMED TO INCLUDE THE DISSENTING COMMON STOCK DETERMINED AS OF THE EFFECTIVE TIME) (THE “Cash Conversion Number”). All other shares of Diablo Common Stock shall be converted into Stock Consideration.

(b) Within five (5) Business Days after the Effective Time, Heritage shall cause the Exchange Agent (as defined below) to effect the allocation among holders of Diablo Common Stock of rights to receive the Cash Consideration and the Stock Consideration as follows:

(i) IF THE AGGREGATE NUMBER OF SHARES OF Diablo Common Stock with respect to which Cash Elections shall have been made (which, for this purpose, shall be deemed to include the Dissenting Common Stock determined as of the Effective Time) (the “Cash Election Number”) exceeds the Cash Conversion Number, then all Stock Election Shares and all Non-Election Shares shall be converted into the right to receive the Stock Consideration, and Cash Election Shares of each holder thereof will be converted into the right to receive the Cash 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 Cash Conversion Number and the denominator of which is the Cash Election Number (with the Exchange Agent to determine, consistent with Section 2.3(a), whether fractions of Cash Election Shares shall be rounded up or down), with the remaining number of such holder’s Cash Election Shares being converted into the right to receive the Stock Consideration; and

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

(A) IF THE SHORTFALL NUMBER IS LESS THAN OR EQUAL TO THE NUMBER OF NON-ELECTION SHARES, THEN ALL STOCK ELECTION SHARES SHALL BE CONVERTED INTO THE RIGHT TO RECEIVE THE STOCK CONSIDERATION, AND THE NON-ELECTION SHARES OF EACH HOLDER THEREOF SHALL CONVERT INTO THE RIGHT TO RECEIVE THE CASH 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 EXCHANGE AGENT TO DETERMINE, CONSISTENT WITH SECTION 2.3(A), WHETHER FRACTIONS OF NON-ELECTION SHARES SHALL BE ROUNDED UP OR DOWN), WITH THE REMAINING NUMBER OF SUCH HOLDER’S NON-ELECTION SHARES BEING CONVERTED INTO THE RIGHT TO RECEIVE THE STOCK CONSIDERATION; OR

(B) 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 CASH CONSIDERATION, AND STOCK ELECTION SHARES OF EACH HOLDER THEREOF SHALL CONVERT INTO THE RIGHT TO RECEIVE THE CASH 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 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 STOCK ELECTION SHARES (WITH THE EXCHANGE AGENT TO DETERMINE, CONSISTENT WITH SECTION 2.3(A), WHETHER FRACTIONS OF STOCK ELECTION SHARES SHALL BE ROUNDED UP OR DOWN), WITH THE REMAINING NUMBER OF SUCH HOLDER’S STOCK ELECTION SHARES BEING CONVERTED INTO THE RIGHT TO RECEIVE THE STOCK CONSIDERATION.

Section 2.4 STOCK OPTIONS. Prior to the Effective Time, in addition to the amount of cash equal to the Total Cash Consideration, Heritage will deposit with the Exchange Agent an amount in cash sufficient to pay the aggregate amount of all cash payments required by this Section 2.4. Each such cash payment will be paid by the Exchange Agent on behalf of Heritage to each holder of an outstanding Diablo option at the Effective Time and reduced by any required withholding Taxes. Prior to the Effective Time, Diablo shall take appropriate action such that each option to purchase shares of the Diablo Common Stock that is outstanding and unexercised immediately prior to the Effective Time including all options granted by Diablo pursuant to The Diablo Valley Bank 2003 Stock Option Plan (the “Stock Option Plan”), shall be canceled by Diablo in consideration of the payment by the Exchange Agent to each holder of such option of an aggregate amount in cash equal to the positive difference, if any, between (a) the Per Share Consideration times the number of shares of Diablo Common Stock as to which such holder has options, and (b) the aggregate exercise price of such options. At the Effective Time, each option to purchase a share of Diablo Common Stock pursuant to the Stock Option Plan shall terminate and be of no further force or effect, and any rights thereunder to purchase shares of Diablo Common Stock shall also terminate and be of no further force or effect.

Section 2.5 Conversion of Dissenting Common Stock.

(a) NO SHARES OF DISSENTING COMMON STOCK THAT ARE ISSUED AND OUTSTANDING AT THE EFFECTIVE TIME AND ARE HELD BY A SHAREHOLDER WHO PROPERLY EXERCISED SUCH SHAREHOLDERS RIGHT UNDER CHAPTER 13 OF THE CGCL SHALL BE CONVERTED INTO THE RIGHT TO RECEIVE THE MERGER CONSIDERATION AND INSTEAD SHALL BE ENTITLED TO SUCH RIGHTS (BUT ONLY SUCH RIGHTS) AS ARE GRANTED BY CHAPTER 13 OF THE CGCL AND TO RECEIVE THE CONSIDERATION AS MAY BE DETERMINED TO BE DUE WITH RESPECT TO SUCH SHARES OF DISSENTING COMMON STOCK PURSUANT TO AND SUBJECT TO THE REQUIREMENTS OF THE CGCL. DIABLO shall give Heritage prompt notice upon receipt by Diablo of any written demands for appraisal rights, withdrawal of such demands, and any other documents received or instruments served pursuant to Chapter 13 of the CGCL and shall give Heritage the opportunity to direct all negotiations and proceedings with respect to such demands. Diablo shall not voluntarily make any payment with respect to any demands for appraisal rights and shall not except with the prior written consent of Heritage, settle or offer to settle such demands.

(b) If any such holder shall have failed to perfect or shall have effectively withdrawn or lost such right prior to the Election Deadline, each of such holder’s shares of Diablo Common Stock shall thereupon be deemed to be Non-Election Shares for all purposes of this Agreement, unless such holder shall thereafter otherwise make a timely Election under this Agreement. If any holder of Dissenting Common Stock shall have so failed to perfect or has effectively withdrawn or lost such holder’s right to dissent from the Merger after the Election Deadline, each of such holder’s shares of Diablo Common Stock shall thereupon be deemed to have been converted into and to have become, as of the Effective Time, the right to receive the Stock Consideration or the Cash Consideration, or a combination thereof, as determined by Heritage in its sole discretion.

ARTICLE III

EXCHANGE OF SHARES

Section 3.1 Election Procedures. Each holder of record of shares of Diablo Common Stock (“Holder”) shall have the right, subject to the limitations set forth in this Article III, to submit an election in accordance with the following procedures:

(a) EACH HOLDER MAY SPECIFY IN A REQUEST MADE IN ACCORDANCE WITH THE PROVISIONS OF THIS SECTION 3.1 (HEREIN CALLED AN “Election”) (i) the number of shares of Diablo Common Stock owned by such Holder with respect to which such Holder desires to make a Stock Election and (ii) the number of shares of Diablo Common Stock owned by such Holder with respect to which such Holder desires to make a Cash Election.

(b) Heritage shall prepare a form reasonably acceptable to Diablo (the “Form of Election”) which shall be mailed to record holders of Diablo Common Stock by the Exchange Agent so as to permit those holders to exercise their right to make an Election prior to the Election Deadline.

(c) The Exchange Agent shall make the Form of Election initially available to Holders not less than twenty (20) Business Days prior to the anticipated Election Deadline and shall use all reasonable efforts to make available as promptly as possible a Form of Election to any shareholder of Diablo who requests such Form of Election following the initial mailing of the Forms of Election and prior to the Election Deadline.

(d) Any Election shall have been made properly only if the person authorized to receive Elections and to act as exchange agent under this Agreement, which person shall be a bank or trust company selected by Heritage (the “Exchange Agent”), pursuant to an agreement (the “Exchange Agent Agreement”) entered into prior to the mailing of the Form of Election to Diablo shareholders, shall have received, by the Election Deadline, a Form of Election properly completed and signed and accompanied by Certificates to which such Form of Election relates or by an appropriate customary guarantee of delivery of such certificates, as set forth in such Form of Election, from a member of any registered national securities exchange or a commercial bank or trust company in the United States; provided, that such Certificates are in fact delivered to the Exchange Agent by the time required in such guarantee of delivery. Failure to deliver shares of Diablo Common Stock covered by such a guarantee of delivery within the time set forth on such guarantee shall be deemed to invalidate any otherwise properly made Election, unless otherwise determined by Heritage, in its sole discretion. As used herein, unless otherwise agreed in advance by the parties, “Election Deadline” means 5:00 p.m. local time (in the city in which the principal office of the Exchange Agent is located) on the day that is the Business Day immediately preceding the date of the Diablo Shareholders Meeting to approve the transactions anticipated by this Agreement. Diablo and Heritage shall cooperate to issue a press release reasonably satisfactory to each of them announcing the date of the Election Deadline not more than 15 Business Days before, and at least 5 Business Days prior to, the Election Deadline.

(e) Any Holder may, at any time prior to the Election Deadline, change or revoke his or her Election by written notice received by the Exchange Agent prior to the Election Deadline accompanied by a properly completed and signed revised Form of Election. Subject to the terms of the Exchange Agent Agreement, if Heritage shall determine in its reasonable discretion that any Election is not properly made with respect to any shares of Diablo Common Stock (neither Heritage nor Diablo nor the Exchange Agent being under any duty to notify any shareholder of any such defect), such Election shall be deemed to be not in effect, and the shares of Diablo Common Stock covered by such Election shall, for purposes hereof, be deemed to be Non-Election Shares, unless a proper Election is thereafter timely made.

(f) Any Diablo shareholder may, at any time prior to the Election Deadline, revoke his or her Election by written notice received by the Exchange Agent prior to the Election Deadline or by withdrawal prior to the Election Deadline of his or her Certificates, or of the guarantee of delivery of such Certificates, previously deposited with the Exchange Agent. All Elections shall be automatically deemed revoked upon receipt by the Exchange Agent of written notification from Heritage or Diablo that this Agreement has been terminated in accordance with Article X.

(g) Subject to the terms of the Exchange Agent Agreement, Heritage, in the exercise of its reasonable discretion, shall have the right to make all determinations, not inconsistent with the terms of this Agreement, governing (i) the validity of the Forms of Election and compliance by any Holder with the Election procedures set forth herein, (ii) the manner and extent to which Elections are to be taken into account in making the determinations prescribed by Section 2.3, (iii) the issuance and delivery of certificates representing the whole number of shares of Heritage Common Stock into which shares of Diablo Common Stock are converted in the Merger and (iv) the method of payment of cash for shares of Diablo Common Stock converted into the right to receive the Cash Consideration and cash in lieu of fractional shares of Heritage Common Stock.

Section 3.2 DEPOSIT OF MERGER CONSIDERATION. At or prior to the Effective Time, Heritage shall deposit, or shall cause to be deposited, with the Exchange Agent, (i) certificates representing the number of shares of Heritage Common Stock sufficient to deliver, and Heritage shall instruct the Exchange Agent to timely deliver, the aggregate Stock Consideration, and (ii) immediately available funds equal to the Total Cash Consideration (together with, to the extent then determinable, any cash payable in lieu of fractional shares pursuant to Section 3.3(f)) (collectively, the “Exchange Fund”) and Heritage shall instruct the Exchange Agent to timely pay the Cash Consideration, and such cash in lieu of fractional shares, in accordance with this Agreement.

Section 3.3 Delivery of Merger Consideration.

(a) AS SOON AS REASONABLY PRACTICABLE AFTER THE EFFECTIVE TIME, BUT IN ANY EVENT PRIOR TO THE FIFTH (5^th) Business Day following the Effective Time, the Exchange Agent shall mail to each holder of record of Certificate(s) which immediately prior to the Effective Time represented outstanding shares of Diablo Common Stock whose shares were converted into the right to receive the Merger Consideration pursuant to Section 2.2 and any cash in lieu of fractional shares of Heritage Common Stock to be issued or paid in consideration therefor who did not properly complete and submit an Election Form, (i) a letter of transmittal (which shall specify that delivery shall be effected, and risk of loss and title to Certificate(s) shall pass, only upon delivery of Certificate(s) (or affidavits of loss in lieu of such Certificate(s))) (the “Letter of Transmittal”) to the Exchange Agent and shall be substantially in such form and have such other provisions as shall be prescribed by the Exchange Agent Agreement and (ii) instructions for use in surrendering Certificate(s) in exchange for the Merger Consideration and any cash in lieu of fractional shares of Heritage Common Stock to be issued or paid in consideration therefor in accordance with Section 3.3(f) upon surrender of such Certificate and any dividends or distributions to which such holder is entitled pursuant to Section 3.3(c).

(b) Upon surrender to the Exchange Agent of its Certificate(s), accompanied by a properly completed Form of Election or a properly completed Letter of Transmittal, a holder of Diablo Common Stock will be entitled to receive, as promptly as practicable after the Effective Time, the Merger Consideration (elected or deemed elected by it, subject to, and in accordance with Sections 2.2 and 2.3) and any cash in lieu of fractional shares of Heritage Common Stock to be issued or paid in consideration therefor in respect of the shares of Diablo Common Stock represented by its Certificate(s). Until so surrendered, each such Certificate shall represent after the Effective Time, for all purposes, only the right to receive, without interest, the Merger Consideration and any cash in lieu of fractional shares of Heritage Common Stock to be issued or paid in consideration therefor upon surrender of such Certificate in accordance with, and any dividends or distributions to which such holder is entitled pursuant to, this Article III.

(c) No dividends or other distributions with respect to Heritage Common Stock shall be paid to the holder of any unsurrendered Certificate with respect to the shares of Heritage Common Stock represented thereby, in each case unless and until the surrender of such Certificate in accordance with this Article III. Subject to the effect of applicable abandoned property, escheat or similar laws, following surrender of any such Certificate in accordance with this Article III the record holder thereof shall be entitled to receive, without interest, (i) the amount of dividends or other distributions with a record date after the Effective Time theretofore payable with respect to the whole shares of Heritage Common Stock represented by such Certificate and not paid and/or (ii) at the appropriate payment date, the amount of dividends or other distributions payable with respect to shares of Heritage Common Stock represented by such Certificate with a record date after the Effective Time (but before such surrender date) and with a payment date subsequent to the issuance of the Heritage Common Stock issuable with respect to such Certificate.

(d) In the event of a transfer of ownership of a Certificate representing Diablo Common Stock that is not registered in the stock transfer records of Diablo, the proper amount of cash and/or shares of Heritage Common Stock shall be paid or issued in exchange therefor to a person other than the person in whose name the Certificate so surrendered is registered if the Certificate formerly representing such Diablo Common Stock shall be properly endorsed or otherwise be in proper form for transfer and the person requesting such payment or issuance shall pay any transfer or other similar Taxes required by reason of the payment or issuance to a Person other than the registered holder of the Certificate or establish to the satisfaction of Heritage that the Tax has been paid or is not applicable.

(e) After the Effective Time, there shall be no transfers on the stock transfer books of Diablo of any shares of Diablo Common Stock that were issued and outstanding immediately prior to the Effective Time other than to settle transfers of Diablo Common Stock that occurred prior to the Effective Time. If, after the Effective Time, Certificates representing such shares are presented for transfer to the Exchange Agent, they shall be cancelled and exchanged for the Merger Consideration and any cash in lieu of fractional shares of Heritage Common Stock to be issued or paid in consideration therefor in accordance with Section 2.3 and the procedures set forth in this Article III.

(f) Notwithstanding anything to the contrary contained in this Agreement, no certificates or scrip representing fractional shares of Heritage Common Stock shall be issued upon the surrender of Certificates for exchange, no dividend or distribution with respect to Heritage Common Stock shall be payable on or with respect to any fractional share, and such fractional share interests shall not entitle the owner thereof to vote or to any other rights of a shareholder of Heritage. In lieu of the issuance of any such fractional share, Heritage shall pay to each former shareholder of Diablo who otherwise would be entitled to receive such fractional share, an amount in cash (rounded to the nearest whole cent) determined by multiplying (i) the Cash Per Share Amount by (ii) the fraction of a share (after taking into account all shares of Diablo Common Stock held by such holder at the Effective Time and rounded to the nearest one thousandth when expressed in decimal form) of Heritage Common Stock to which such holder would otherwise be entitled to receive pursuant to Section 2.2.

(g) Any portion of the Exchange Fund that remains unclaimed by the shareholders of Diablo as of six months of the Effective Time shall be paid to Heritage. Any former shareholders of Diablo who have not theretofore complied with this Article III shall thereafter look only to Heritage with respect to the Merger Consideration, any cash in lieu of any fractional shares and any unpaid dividends and distributions on the Heritage Common Stock deliverable in respect of each share of Diablo Common Stock such shareholder holds as determined pursuant to this Agreement, in each case, without any interest thereon. Notwithstanding the foregoing, none of Heritage, Diablo, the Exchange Agent or any other person shall be liable to any former holder of shares of Diablo Common Stock for any amount delivered in good faith to a public official pursuant to applicable abandoned property, escheat or similar laws.

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

(i) Notwithstanding anything to the contrary contained herein, no certificates representing shares of Heritage Common Stock shall be delivered to a Diablo Shareholder who is an “affiliate” of Diablo for purposes of Rule 145 under the Securities Act of 1933, as amended (the “Securities Act”) unless such “affiliate” shall have theretofore executed and delivered to a written agreement from such person referred to in Section 7.8.

(j) Holders of Certificates representing shares of Diablo Common Stock shall not be entitled to vote as holders of shares of Heritage Common Stock until such Certificates representing Diablo Common Stock have been exchanged for shares of Heritage Common Stock as provided in this Article III.

Section 3.4 WITHHOLDING RIGHTS. The Exchange Agent (or, subsequent to six months from the Effective Time, Heritage) shall be entitled to deduct and withhold from any cash portion of the Merger Consideration, any cash in lieu of fractional shares of Heritage Common Stock, cash dividends or distributions payable pursuant to Section 3.3(c) hereof and any other cash amounts otherwise payable pursuant to this Agreement to any holder of Diablo Common Stock or Diablo stock options (pursuant to Section 2.4) such amounts as the Exchange Agent or Heritage, as the case may be, is required to deduct and withhold under the Code, or any provision of state, local or foreign Tax law, with respect to the making of such payment. To the extent the amounts are so withheld by the Exchange Agent or Heritage, as the case may be, such withheld amounts shall be treated for all purposes of this Agreement as having been paid to the holder of shares of Diablo Common Stock in respect of whom such deduction and withholding was made by the Exchange Agent or Heritage, as the case may be.

Section 3.5 No Liability. Neither Heritage, HBC, Diablo nor the Exchange Agent shall be liable to any holder of shares of Diablo Common Stock for any shares of Heritage Common Stock (or dividends or distributions with respect thereto) or cash delivered to a public official pursuant to any applicable abandoned property, escheat or similar law.

Diablo is not a Subsidiary of any Person.

(e) Capitalization. The entire authorized capital stock of Diablo consists of (i) 20,000,000 shares of Diablo Common Stock, of which 2,502,146 are issued and outstanding (subject to the exercise of Diablo stock options from and after the date hereof), and 715,350 additional shares of which have been reserved for issuance to holders of outstanding Diablo stock options under the Stock Option Plan (subject to the exercise of Diablo stock options from and after the date hereof), and (ii) 10,000,000 shares of preferred stock, no par value per share, of which 207,061 shares of Series A Preferred Stock are issued and outstanding (“Diablo Preferred Stock”).

Except as set forth on the Diablo Disclosure Schedule, the exercise price of each stock option issued pursuant to the Stock Option Plan was the price on the date of grant in accordance with GAAP and applicable law. Except for options issued under the Stock Option Plan, there are no (i) other outstanding equity securities of any kind or character, (ii) outstanding subscriptions, options, convertible securities, rights, warrants, calls or other agreements or commitments of any kind issued or granted by, or binding upon, Diablo to purchase or otherwise acquire any security of or equity interest in Diablo or (iii) outstanding subscriptions, options, rights, warrants, calls, convertible securities, irrevocable proxies or other agreements or commitments obligating Diablo to issue any shares of, restricting the transfer of or otherwise relating to shares of its capital stock of any class.

(f) Financial Statements and Accounting Records. Diablo has furnished to Heritage true and complete copies of (i) the audited balance sheets of Diablo as of December 31, 2003, 2004 and 2005, and the related audited statements of income, stockholders’ equity and cash flows for the years ended December 31, 2003, 2004 and 2005, (ii) an unaudited balance sheet of Diablo as of September 30, 2006, and the related unaudited statement of income for the nine-month period ended September 30, 2006 (such balance sheets and the related statements of income, stockholders’ equity and cash flows are collectively referred to herein as the “Diablo Financial Statements”). The Diablo Financial Statements fairly present, in all material respects, the financial position of Diablo as of the respective dates thereof and the results of operations and changes in financial position of Diablo for the periods then ended, in conformity with GAAP, applied on a basis consistent with prior periods (subject, in the case of the unaudited interim financial statements, to normal year-end adjustments and the fact that they do not contain all of the footnote disclosures required by GAAP). Diablo makes and keeps accurate books and records and maintains a system of internal accounting controls over financial reporting that are sufficient to provide reasonable assurance that transactions are properly recorded and records are kept which accurately and fairly reflect, in all material respects, financial activities of Diablo, so as to permit the preparation of Diablo’s financial statements in conformity with GAAP. Since December 31, 2005, Diablo has not been advised of (i) any significant deficiencies in the design or operation of internal controls that could adversely affect the ability of Diablo to record, process, summarize and report financial data and (ii) any fraud, whether or not material, that involves management or other employees who have a significant role in the internal controls of Diablo.

(g) Allowance for Loan Losses.

(i) THE ALLOWANCE FOR LOAN LOSSES SHOWN ON THE Diablo Financial Statements as of September 30, 2006 (and as shown on any financial statements to be delivered by Diablo to Heritage pursuant to Section 7.2(b) hereof), to the knowledge of Diablo, as of such date was (and will be as of such subsequent Diablo Financial Statements) adequate in all respects to provide for losses, net of recoveries relating to loans previously charged off, on loans outstanding, and contained (or will contain) an additional amount of unallocated reserves for future losses at a level considered adequate under the standards applied by applicable regulatory authorities and based upon generally accepted practices. To the knowledge of Diablo, the aggregate principal amount of loans contained (or that will be contained) in the loan portfolio of Diablo as of September 30, 2006 (and as of the dates of any financial statements to be delivered by Diablo to Heritage pursuant to Section 7.2(b) hereof), in excess of such reserve, was (and will be) fully collectible. Diablo has calculated its allowance for loan losses in accordance with GAAP as applied to banking institutions and in accordance with all applicable rules and regulations.

(ii) The Disclosure Schedule lists all Nonperforming Assets as of September 30, 2006. The sum of the aggregate amount of all Nonperforming Assets (as defined below) and all troubled debt restructurings (as defined under GAAP) on the books of Diablo as of September 30, 2006 does not exceed 0.25% of total loans at the date hereof. “Nonperforming Assets” shall mean (i) all loans and leases (A) that are contractually past due 90 days or more in the payment of principal and/or interest, (B) that are on nonaccrual status, (C) where a reasonable doubt exists, in the reasonable judgment of Diablo, as to the timely future collectibility of principal and/or interest, whether or not interest is still accruing or the loan is less than 90 days past due, (D) where the interest rate terms have been reduced and/or the maturity dates have been extended subsequent to the agreement under which the loan was originally created due to concerns regarding the borrower’s ability to pay in accordance with such initial terms, (E) where a specific reserve allocation exists in connection therewith, or (F) that have been classified “Doubtful,”“Loss” or the equivalent thereof by any regulatory authority, and (ii) all assets classified as real estate owned (“REO”) and other assets acquired through foreclosure or repossession. Other than as set forth in the Diablo Disclosure Schedule, Diablo has no Nonperforming Assets as defined herein.

(h) LOANS; Investments.

(i) EXCEPT AS OTHERWISE set forth in the Disclosure Schedule, each loan reflected as an asset on the Diablo Financial Statements dated as of September 30, 2006, and each loan originated or acquired after such date, constitutes the legal, valid and binding obligation of the obligor named therein, enforceable in accordance with its terms, except to the extent that the enforceability thereof may be limited by bankruptcy, insolvency, reorganization, moratorium or similar laws or equitable principles or doctrines. Except as set forth in the Diablo Disclosure Schedule, all such loans are, and at the Effective Time will be, free and clear of any security interest, lien, encumbrance or other charge and do not, and will not at the Effective Time, include any provision for prepayment penalties in violation of any law or regulation. All currently outstanding loans of Diablo, including any current extensions of any loan, were solicited, originated and currently exist in material compliance with all applicable requirements of federal and state law and regulations promulgated thereunder. There are no oral modifications or amendments or additional agreements related to the loans that are not reflected in Diablo’s records, and to the knowledge of Diablo no claim of defense as to the enforcement of any loan has been asserted, and Diablo has no knowledge of any acts or omissions that would give rise to any claim or right of rescission, set off, counterclaim or defense. Except as set forth in the Disclosure Schedule, there is no loan or other asset of Diablo that has been classified by Diablo or its examiners as “Watchlist,”“Special Mention,”“Substandard,”“Doubtful” or “Loss” (identified by borrower, outstanding amounts and summary of loan terms).

(ii) All guarantees of indebtedness owed to Diablo, including but not limited to those of the Federal Housing Administration, the Small Business Administration, and other state and federal agencies, are, to the knowledge of Diablo, valid and enforceable, except to the extent enforceability thereof may be limited by applicable bankruptcy, insolvency, reorganization, moratorium or similar laws or equitable principles or doctrines.

(iii) Except as set forth in the Disclosure Schedule and except for pledges to secure public and trust deposits, none of the investments reflected in the Diablo Financial Statements dated as of September 30, 2006 under the heading “Investment Securities,” and none of the investments made by Diablo since September 30, 2006, is subject to any restriction, whether contractual or statutory, which materially impairs the ability of Diablo to freely dispose of such investment at any time, other than those restrictions imposed on securities held for investment under GAAP. With respect to all material repurchase agreements to which Diablo is a party, Diablo has a valid, perfected first lien or security interest in the government securities or other collateral securing each such repurchase agreement, and the value of the collateral securing each such repurchase agreement equals or exceeds the amount of the debt secured by such collateral under such agreement. Except as set forth in the Disclosure Schedule and except for a transaction involving less than $50,000, Diablo has not sold or otherwise disposed of any assets in a transaction in which the acquiror of such assets or other person has the right, either conditionally or absolutely, to require Diablo to repurchase or otherwise reacquire any such assets.

(iv) Set forth in the Disclosure Schedule is a complete and accurate list of each investment and debt security, mortgage-backed and related securities, marketable equity securities and securities purchased under agreements to resell owned by Diablo showing as of September 30, 2006 the carrying values and estimated fair values of investment and debt securities, the gross carrying value and estimated fair value of the mortgage-backed and related securities and the estimated cost and estimated fair value of the marketable equity securities.

(v) All United States Treasury securities, obligations of other United States Government agencies and corporations, obligations of States of United States and their political subdivisions, and other investment securities classified as “held to maturity” and “available for sale” held by Diablo, as reflected in the Diablo Financial Statements dated September 30, 2006 were classified and accounted for in accordance with GAAP.

Section 6.7 Benefit Plans.

(A) SUBJECT TO SECTION 6.7(B), (C) AND (D), AS SOON AS ADMINISTRATIVELY PRACTICABLE AFTER THE EFFECTIVE TIME, HERITAGE AND HBC SHALL TAKE ALL REASONABLE ACTION SO THAT EMPLOYEES OF DIABLO SHALL BE ENTITLED TO PARTICIPATE IN EACH EMPLOYEE BENEFIT PLAN, PROGRAM OR ARRANGEMENT OF HERITAGE AND HBC OF GENERAL APPLICABILITY (THE “HERITAGE AND HBC BENEFIT PLANS”) TO THE SAME EXTENT AS SIMILARLY-SITUATED EMPLOYEES OF HERITAGE AND HBC (IT BEING UNDERSTOOD THAT INCLUSION OF THE EMPLOYEES OF DIABLO IN THE HERITAGE AND HBC BENEFIT PLANS MAY OCCUR AT DIFFERENT TIMES WITH RESPECT TO DIFFERENT PLANS), PROVIDED HOWEVER, THAT COVERAGE SHALL BE CONTINUED UNDER CORRESPONDING BENEFIT PLANS OF DIABLO UNTIL SUCH EMPLOYEES ARE PERMITTED TO PARTICIPATE IN THE HERITAGE AND HBC BENEFIT PLANS AND PROVIDED FURTHER, HOWEVER, THAT NOTHING CONTAINED HEREIN SHALL REQUIRE HERITAGE OR HBC TO MAKE ANY GRANTS TO ANY FORMER EMPLOYEE OF DIABLO UNDER ANY DISCRETIONARY EQUITY COMPENSATION PLAN OF HERITAGE AND HBC. HERITAGE AND HBC SHALL CAUSE EACH HERITAGE AND HBC BENEFIT PLAN IN WHICH EMPLOYEES OF DIABLO ARE ELIGIBLE TO PARTICIPATE TO RECOGNIZE, FOR PURPOSES OF DETERMINING ELIGIBILITY TO PARTICIPATE IN, THE VESTING OF BENEFITS AND FOR ALL OTHER PURPOSES (BUT NOT FOR ACCRUAL OF PENSION BENEFITS OR ALLOCATION OF SHARES UNDER THE HERITAGE ESOP PLAN) UNDER THE HERITAGE AND HBC BENEFITS PLANS, THE SERVICE OF SUCH EMPLOYEES WITH DIABLO TO THE SAME EXTENT AS SUCH SERVICE WAS CREDITED FOR SUCH PURPOSE BY DIABLO, PROVIDED, HOWEVER, THAT SUCH SERVICE SHALL NOT BE RECOGNIZED TO THE EXTENT THAT SUCH RECOGNITION WOULD RESULT IN A DUPLICATION OF BENEFITS. NOTHING HEREIN SHALL LIMIT THE ABILITY OF HERITAGE AND HBC TO AMEND OR TERMINATE ANY OF DIABLO’S BENEFIT PLANS IN ACCORDANCE WITH AND TO THE EXTENT PERMITTED BY THEIR TERMS AT ANY TIME PERMITTED BY SUCH TERMS.

(b) AT AND FOLLOWING THE EFFECTIVE TIME, HERITAGE AND HBC SHALL HONOR, AND SHALL CONTINUE TO BE OBLIGATED TO PERFORM, IN ACCORDANCE WITH THEIR TERMS, AND BENEFIT OBLIGATIONS TO, AND CONTRACTUAL RIGHTS OF FORMER EMPLOYEES OF DIABLO EXISTING AS OF THE EFFECTIVE DATE, AS WELL AS ALL EMPLOYMENT, SEVERANCE, DEFERRED COMPENSATION, “CHANGE-IN-CONTROL” AGREEMENTS, PLANS OR POLICIES OF DIABLO SET FORTH ON SECTION 5.1(K) OF THE DISCLOSURE SCHEDULE (UNLESS TERMINATED BY ANY AGREEMENT ENTERED INTO AS OF OR AFTER THE DATE HEREOF), PROVIDED SUCH AGREEMENTS, PLANS OR POLICIES ARE NOT SUPERSEDED BY SIMILAR AGREEMENT, PLANS OR POLICIES OF HERITAGE OR HBC, PROVIDED FURTHER, THIS PROVISION SHALL NOT PREVENT HERITAGE OR HBC FROM AMENDING, SUSPENDING, OR TERMINATING ANY SUCH AGREEMENTS TO THE EXTENT PERMITTED BY THE RESPECTIVE TERMS OF SUCH AGREEMENTS PLANS OR POLICIES.

(c) Heritage in its sole discretion, may elect to terminate the Diablo 401(k) Plan or to discontinue contributions to the Diablo 401(k) Plan following the Effective Time, to cause Diablo to terminate the Diablo 401(k) Plan to be effective at the Effective Time, or to merge the Diablo 401(k) Plan with and into the Heritage 401(k) Plan after the Effective Time. In no event shall the Diablo 401(k) Plan be merged with and into the Heritage 401(k) Plan, however, unless Heritage determines, in its reasonable judgment, that: (i) the Diablo 401(k) Plan is a qualified plan under Section 401(a) of the Code, both as to the form of the Diablo 401(k) Plan and as to its operation; and (ii) there are no facts in existence that would be reasonably likely to adversely affect the qualified status of the Diablo 401(k) Plan. If Heritage determines in its sole discretion not to merge the Diablo 401(k) Plan into the Heritage 401(k) Plan and that the Diablo 401(k) Plan should be terminated prior to the Effective Time, Diablo agrees to use its commercially reasonable efforts to have the Diablo 401(k) Plan terminated prior to the Effective Time and to obtain an IRS determination that the Diablo 401(k) Plan continues to be qualified upon termination.

(d) Employees of Diablo who are covered under Diablo dental and health insurance plans immediately prior to the Effective Date shall become eligible to participate in any of the medical, dental, disability or other health plans of Heritage or HBC. Heritage shall, or shall cause HBC to, (i) waive any preexisting conditions (subject, in the case of plans other than medical plans (which medical plans include, among other benefits, in-patient/out-patient hospital care, mental health and prescription coverage), to Heritage’s reasonable efforts to obtain carrier approval), waiting periods and actively at work requirements under such plans, and (ii) cause such plans to honor any expenses incurred by such employees and their beneficiaries under similar plans of Diablo during the portion of the calendar year prior to such participation for purposes of satisfying applicable deductibles, co-insurance requirements and maximum out-of-pocket expenses. Notwithstanding the foregoing, no such action will cause the plans to violate applicable legal requirements.

Diablo shall enforce, to the fullest extent permitted under applicable law, the provisions of any standstill, confidentiality or similar agreement entered into by Diablo or any of its Affiliates or representatives including, but not limited to, where necessary to obtaining injunctions to prevent any breaches of such agreements and to enforce specifically the term and provisions thereof in any court having jurisdiction.

(c) In addition to the obligations of Diablo set forth in paragraph (a), on the date of receipt or occurrence thereof, Diablo shall advise Heritage of any request for information with respect to any Acquisition Proposal or of any Acquisition Proposal, or any inquiry, proposal, discussion or negotiation with respect to any Acquisition Proposal, the terms and conditions of such request, Acquisition Proposal, inquiry, proposal, discussion or negotiation and Diablo shall, within two (2) Business Days of the receipt thereof, promptly provide to Heritage copies of any written materials received by Diablo in connection with any of the foregoing, and the identity of the Person making any such Acquisition Proposal or such request, inquiry or proposal or with whom any discussion or negotiation is taking place.

Diablo shall promptly provide to Heritage any non-public information concerning Diablo, provided to any other Person in connection with any Acquisition Proposal which was not previously provided to Heritage.

(d) Diablo shall immediately request each Person which has heretofore executed a confidentiality agreement in connection with its consideration of acquiring Diablo or any portion thereof to return all confidential information heretofore furnished to such Person by or on behalf of Diablo, and Diablo shall use its commercially reasonable efforts to have such information returned.

Section 7.7 SHAREHOLDER AGREEMENTS. Each director and executive officer of Diablo, as a shareholder of Diablo Common Stock, has executed and delivered to Heritage on the date of this Agreement a shareholder agreement (each, a “Shareholder Agreement”) substantially in the form attached hereto as Exhibit B, committing each such person, among other things, to vote his or her shares of Diablo Common Stock in favor of this Agreement and the Merger at the shareholders’ meeting held for that purpose, granting a proxy for such shares to Heritage, and to certain representations and covenants.

Section 7.10 Access to Employees. Diablo shall cooperate with Heritage with respect to any formal meetings or interviews with one or more employees called or arranged by Diablo and held for the purpose of discussing the transactions contemplated by this Agreement or their effect on such employees, with Heritage given the opportunity to participate in such meetings or interviews. This section 7.10 is not intended to apply to casual conversations about the transaction or informal meetings initiated by employees, or to prohibit discussion in general, but rather to allow Heritage a role in the formal presentation of the transaction to employees, and an opportunity to participate in the significant, formal meetings at which the transaction is explained and discussed. Heritage shall have the right, but not the obligation, within thirty (30) Business Days prior to the Effective Day, to provide training to employees of Diablo who will become employees of Heritage. Such training shall be at the expense of Heritage and shall be conducted during normal business hours.

Section 7.11 Transition. Commencing following the date hereof, and in all cases subject to applicable law and regulation, Diablo shall cooperate with Heritage and HBC to facilitate the integration of the parties and their respective businesses. Without limiting the generality of the foregoing, from the date hereof through the Closing Date and consistent with the performance of their day-to-day operations and the continuous operation of Diablo in the ordinary course of business, Diablo shall use its reasonable efforts to provide reasonable support, including requesting reasonable support from its outside contractors and vendors, and to reasonably assist Heritage and HBC in performing all tasks deemed reasonably necessary to integrate their respective businesses.

Among other things, Diablo shall cooperate with Heritage to establish a mutually agreeable project plan to effectuate the conversion; use their commercially reasonable efforts to have Diablo’s outside contractors continue to support both the conversion effort and its needs until the conversion can be established; provide, or use its commercially reasonable efforts to obtain from any outside contractors, all data or other files and layouts requested by Heritage for use in planning the conversion, as soon as reasonably practicable.

Subject to the other provisions of this Section 7, each share of Diablo Common Stock issued and outstanding immediately prior to the Effective Time (other than Dissenting Common Stock and Treasury Shares) shall at the election of the holder thereof, by virtue of the Merger, be converted into the right to receive the following without interest:

(i) for each share of Diablo Common Stock with respect to which an election to receive cash has been effectively made and not revoked or deemed revoked (a “Cash Election”), the right to receive in cash an amount (the “Cash Consideration”) equal to the Per Share Consideration (the “Cash Per Share Amount”) (collectively, the “Cash Election Shares”);

(ii) for each share of Diablo Common Stock with respect to which an election to receive stock has been effectively made and not revoked or deemed revoked (a “Stock Election”), the right to receive the fraction of a share of Heritage Common Stock (the “Stock Consideration”) equal to the Exchange Ratio (collectively, the “Stock Election Shares”); and,

The Cash Consideration and Stock Consideration are sometimes referred to herein collectively on the “Merger Consideration.”

(b) If, between the date hereof and the Effective Time, the outstanding shares of Heritage Common Stock shall have been increased, decreased, changed into or exchanged for a different number or kind of shares or securities as a result of a reorganization, recapitalization, reclassification, stock dividend, stock split, reverse stock split, or other similar change in capitalization (a “Share Adjustment”), then the shares of Heritage Common Stock into which a share of Diablo Common Stock shall be converted pursuant to this Section 7 shall be appropriately and proportionately adjusted so that each shareholder of Diablo shall be entitled to receive the Exchange Ratio such shareholder would have received pursuant to such Share Adjustment had the record date therefor been immediately following the Effective Time.

A-2

(c) HBC. At the Effective Time, each share of HBC Common Stock issued and outstanding immediately prior to the Effective Time shall not be effected by the Merger and shall remain as an issued and outstanding share of common stock of the Surviving Corporation.

8. Proration.

(a) Notwithstanding any other provision contained herein, the number of shares of Diablo Common Stock that will be converted into Cash Consideration pursuant to Section 7 shall be equal to the quotient obtained by dividing (x) the Total Cash Consideration, by (y) the Per Share Consideration (which, for this purpose, shall be deemed to include the Dissenting Common Stock determined as of the Effective Time) (the “Cash Conversion Number”). All other shares of Diablo Common Stock shall be converted into Stock Consideration.

(b) Within five (5) Business Days after the Effective Time, Heritage shall cause the Exchange Agent to effect the allocation among holders of Diablo Common Stock of rights to receive the Cash Consideration and the Stock Consideration as follows:

(i) If the aggregate number of shares of Diablo Common Stock with respect to which Cash Elections shall have been made (which, for this purpose, shall be deemed to include the Dissenting Common Stock determined as of the Effective Time) (the “Cash Election Number”) exceeds the Cash Conversion Number, then all Stock Election Shares and all Non-Election Shares shall be converted into the right to receive the Stock Consideration, and Cash Election Shares of each holder thereof will be converted into the right to receive the Cash 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 Cash Conversion Number and the denominator of which is the Cash Election Number (with the Exchange Agent to determine, consistent with Section 8(a), whether fractions of Cash Election Shares shall be rounded up or down), with the remaining number of such holder’s Cash Election Shares being converted into the right to receive the Stock Consideration; and

(a) If the Shortfall Number is less than or equal to the number of Non-Election Shares, then all Stock Election Shares shall be converted into the right to receive the Stock Consideration, and the Non-Election Shares of each holder thereof shall convert into the right to receive the Cash 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 Exchange Agent to determine, consistent with Section 8(a), whether fractions of Non-Election Shares shall be rounded up or down), with the remaining number of such holder’s Non-Election Shares being converted into the right to receive the Stock Consideration; or

A-3

(b) 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 Cash Consideration, and Stock Election Shares of each holder thereof shall convert into the right to receive the Cash 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 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 Stock Election Shares (with the Exchange Agent to determine, consistent with Section 8(a), whether fractions of Stock Election Shares shall be rounded up or down), with the remaining number of such holder’s Stock Election Shares being converted into the right to receive the Stock Consideration.

9. Counterparts. This Agreement of Merger may be executed in one or more counterparts, each of which shall be deemed to be an original but all of which together shall constitute one agreement.

10. Governing Law. This Agreement of Merger shall be governed in all respects, including, but not limited to, validity, interpretation, effect and performance, by the laws of the State of California.

11. Amendment. Subject to applicable law, this Agreement of Merger may be amended, modified or supplemented only by written agreement of Diablo and HBC at any time prior to the Effective Time, except that after the Diablo Shareholders Meeting, no amendment shall be made which by law requires further approval by the shareholders of Diablo without obtaining such approval.

12. Waiver. Any of the terms or conditions of this Agreement of Merger may be waived at any time by whichever of the parties hereto is, or the shareholders of which are, entitled to the benefit thereof by action taken by the Board of Directors of such waiving party.

WHEREAS, Heritage, Heritage Bank of Commerce, a California banking corporation (“HBC”) and Diablo Valley Bank, a California banking corporation (“Diablo”), have entered into that certain Agreement and Plan of Merger (the “Agreement”), dated as of February 8, 2007, pursuant to which Diablo will be merged (the “Merger”), with and into HBC whereupon each share of Diablo common stock (“Diablo Common Stock”) will be converted into the right to receive the consideration set forth in the Agreement; and

WHEREAS, as a condition to its willingness to enter into the Agreement, Heritage has required that each executive officer and director of Diablo, as an owner of Diablo Common Stock, enter into, and the Shareholder has agreed to enter into, this Shareholder Agreement.

NOW, THEREFORE, in consideration of the foregoing, for good and valuable consideration, the parties hereby agree as follows:

1. Representations and Warranties of the Shareholder. The Shareholder hereby represents and warrants to Heritage as follows:

(a) Authority; No Violation. The Shareholder has all necessary power and authority to enter into and perform all of such Shareholder’s obligations hereunder. The execution, delivery and performance of this Shareholder Agreement by the Shareholder will not violate any other agreement to which such Shareholder is a party, including any voting agreement, shareholders’ agreement, trust agreement or voting trust. This Shareholder Agreement has been duly and validly executed and delivered by the Shareholder (and the Shareholder’s spouse, if the Shares (as defined below) constitute community property) and constitutes a valid and binding agreement of the Shareholder and such spouse, enforceable against the Shareholder and the Shareholder’s spouse in accordance with its terms.

(b) Ownership of Shares. The Shareholder is the beneficial owner or record holder of the number of shares of Diablo Common Stock indicated under the Shareholder’s name on the signature page hereto (the “Existing Shares”, and together with any shares of Diablo Common Stock acquired by the Shareholder after the date hereof, the “Shares”) and, as of the date hereof, the Existing Shares constitute all the shares of Diablo Common Stock owned of record or beneficially by the Shareholder. With respect to the Existing Shares, subject to applicable community property laws, the Shareholder has sole voting power and sole power to issue instructions with respect to the matters set forth in Section 2 hereof, sole power of disposition, sole power to demand appraisal rights and sole power to engage in actions set forth in Section 2 hereof, with no restrictions on the voting rights, rights of disposition or otherwise, subject to applicable laws and the terms of this Agreement.

B-1

2. Voting Agreement and Agreement Not to Transfer.

(a) The Shareholder hereby agrees to vote all of the Shares held by the Shareholder (i) in favor of the Merger, the Agreement and the transactions contemplated by the Agreement; (ii) against any action or agreement that would result in a breach in any material respect of any covenant, representation or warranty or any other obligation or agreement of Diablo under the Agreement; and (iii) except with the prior written consent of Heritage or as otherwise contemplated in the Agreement, against the following actions (other than the Merger and the transactions contemplated by the Agreement): (A) any extraordinary corporate transactions, such as a merger, consolidation or other business combination involving Diablo; (B) any sale, lease or transfer of a material amount of the assets of Diablo; (C) any change in the majority of the board of Diablo; (D) any material change in the present capitalization of Diablo; (E) any amendment of Diablo’s Articles of Incorporation; (F) any other material change in Diablo’s corporate structure or business; or (G) any other action which is intended, or could reasonably be expected to, impede, interfere with, delay, postpone, discourage or materially adversely affect the contemplated economic benefits to Heritage of the transactions contemplated by the Agreement. The Shareholder shall not enter into any agreement or understanding with any person or entity prior to the Termination Date (as defined below) to vote or give instructions after the Termination Date in any manner inconsistent with clauses (i), (ii) or (iii) of the preceding sentence.

(b) Until the earlier of the termination of this Agreement or the Effective Time, the Shareholder will not, directly or indirectly: sell, transfer, exchange, pledge, assign, hypothecate, encumber, tender or otherwise dispose of (collectively, a “Transfer”), or enforce or permit execution of the provisions of any redemption, share purchaser or sale, recapitalization or other agreement with Diablo or any other Person or enter into any contract, option or other agreement, arrangement or understanding with respect to the Transfer of, directly or indirectly, any of the Shares or any securities convertible into or exercisable for Shares, any other capital stock of Diablo or any interest in any of the foregoing with any Person; enter into swap or any other agreement or any transaction that transfers, in whole or in part, directly or indirectly, the economic consequence of ownership of the Shares; solicit, initiate, encourage, or facilitate, any inquiries or the making of any proposal or offer with respect to any Acquisition Proposal; take any action that would make any of such Shareholder’s representations or warranties contained herein untrue or incorrect in any material respect or have the effect of preventing or disabling such Shareholder from performing such Shareholder’s obligations under this Agreement.

3. Cooperation. The Shareholder agrees that he/she will not directly or indirectly solicit any inquiries or proposals from any person relating to any proposal or transaction for the disposition of the business or assets of Diablo or any of its subsidiaries, or the acquisition of voting securities of Diablo or any subsidiary of Diablo or any business combination between Diablo or any subsidiary of Diablo and any person other than Heritage or HBC

4. Shareholder Capacity. The Shareholder is entering this Shareholder Agreement in his or her capacity as the record or beneficial owner of the Shareholder’s Shares, and not in his or her capacity as a director of Diablo. Nothing in this Shareholder Agreement shall be deemed in any manner to limit the discretion of any Shareholder to take any action, or fail to take any action, in his or her capacity as a director of Diablo, that may be required of such Shareholder in the exercise of his or her duties and responsibilities as a director of Diablo.

B-2

5. Termination. The obligations of the Shareholder shall terminate upon the consummation of the Merger. If the Merger is not consummated, the obligations of the Shareholder hereunder shall terminate upon the termination of the Agreement.

Heritage Commerce Corp

▇▇▇ ▇▇▇▇▇▇▇ ▇▇▇▇▇▇▇▇▇

▇▇▇ ▇▇▇▇, ▇▇ ▇▇▇▇▇

Ladies and Gentlemen:

I have been advised that as of the date hereof I may be deemed to be an “affiliate” of Diablo Valley Bank, a California banking corporation (“Diablo”), as the term “affiliate” is (i) defined for purposes of paragraphs (c) and (d) of Rule 145 (“Rule 145”) of the Rules and Regulations (the “Rules and Regulations”) of the Securities and Exchange Commission (the “SEC”) under the Securities Act of 1933, as amended (the “Act”). I have been further advised that pursuant to the terms of the Agreement and Plan of Merger, dated as of February __, 2007 (the “Merger Agreement”), by and among you (“Heritage”), Heritage Bank of Commerce, a California banking corporation (“HBC”) and Diablo, Diablo will be merged with and into HBC, and that as a result of the Merger, I may be eligible to receive shares of Heritage Common Stock (as defined in the Merger Agreement) in exchange for shares of Diablo Common Stock (as defined in the Merger Agreement) owned by me.

I hereby represent, warrant and covenant to Heritage that in the event I receive any Heritage Common Stock pursuant to the Merger:

1. I shall not make any sale, transfer or other disposition of the Heritage Common Stock in violation of the Act or the Rules and Regulations.

2. I have carefully read this letter and the Merger Agreement and discussed its requirements and other applicable limitations upon my ability to sell, transfer or otherwise dispose of Heritage Common Stock to the extent I believed necessary, with my counsel or with counsel for Diablo.

3. I have been advised that the issuance of Heritage Common Stock to me pursuant to the Merger Agreement will be registered with the SEC on a registration statement on Form S-4. However, I have also been advised that, since at the time the Merger will be submitted to the shareholders of Diablo for approval, I may be an “affiliate” of Diablo, any sale or disposition by me of any of the Heritage Common Stock may, under current law, only be made in accordance with the provisions of paragraph (d) of Rule 145 under the Act, pursuant to an effective registration statement under the Act or pursuant to an exemption thereunder. I agree that I will not sell, transfer, or otherwise dispose of Heritage Common Stock issued to me in the Merger unless (i) such sale, transfer or other disposition has been registered under the Act; (ii) such sale, transfer or other disposition is made in conformity with the volume and other limitations of Rule 145 promulgated by the SEC under the Act; or (iii) in the written opinion of counsel, which opinion and counsel shall be reasonably acceptable to Heritage, such sale, transfer or other disposition is otherwise exempt from registration under the Act.

C-1

4. I understand that Heritage is under no obligation to register the sale, transfer or other disposition of the Heritage Common Stock by me or on my behalf or to take any other action necessary to make compliance with an exemption from registration available other than its obligations to maintain current in its reports under the Securities Exchange Act of 1939.

5. I understand that stop transfer instructions will be given to Heritage’s transfer agents with respect to Heritage Common Stock and that there will be placed on the certificates for the Heritage Common Stock issued to me, or any substitutions therefor issued during the period referred to in Rule 145(d), a legend stating in substance:

“The securities represented by this certificate have been issued in a transaction to which Rule 145 promulgated under the Securities Act of 1933 applies and may be sold or otherwise transferred only in compliance with the requirements of Rule 145 or pursuant to a registration statement under said act or an exemption from such registration.”

It is understood and agreed that this letter agreement shall terminate and be of no further force and effect and the legend set forth in paragraph (5) above shall be removed by delivery of substitute certificates without such legend, and the related stop transfer restrictions shall be lifted forthwith, if (i) any such shares of Heritage Common Stock shall have been registered under the Act for sale, transfer or other disposition by me or on my behalf and are sold, transferred or otherwise disposed of, or (ii) any such shares of Heritage Common Stock are sold in accordance with the provisions of paragraphs (c), (e), (f) and (g) of Rule 144 promulgated under the Act, or (iii) I am not at the time an affiliate of Heritage and have been the beneficial owner of the Heritage Common Stock for at least one year (or such other period as may be prescribed by the Act, and the rules and regulations promulgated thereunder), and Heritage has filed with the SEC all of the reports it is required to file under the Securities Exchange Act of 1934, as amended, during the preceding 12 months or as specified in Rule 144, or (iv) I am not and have not been for at least three months an affiliate of Heritage and have been the beneficial owner of the Heritage Common Stock for at least two years (or such other period as may be prescribed by the Act and the Rules and Regulations), or (v) Heritage shall have received a letter from the Staff of the SEC, or a written opinion of counsel, which opinion and counsel shall be reasonably acceptable to Heritage, to the effect that the stock transfer restrictions and the legend are not required.

Sincerely,
