ARTICLE I
THE MERGER

Section 1.01 The Merger. On the terms and subject to the conditions set forth in this Agreement, and pursuant to the provisions of the California General Corporation Law (“CGCL”) and, to the extent applicable, the California Financial Code “(CFC”) and the rules and regulations promulgated by the California Department of Business Oversight (“DBO”), at the Effective Time, UAB shall merge with and into HBC (the “Merger”) and the separate corporate existence of UAB shall cease. HBC shall be the surviving corporation in the Merger (sometimes hereinafter referred to as the “Surviving Corporation”).

Section 1.02 Effective Time. On the terms and conditions set forth in this Agreement, the Closing of the Merger (the “Closing”) shall take place as soon as practicable, but in no event later than the fifth (5th) business day after which each of the conditions set forth in Article VI of this Agreement has been satisfied or waived (other than those conditions that by their nature are to be satisfied or waived at Closing) or such other time as the parties may agree, at the offices of Buchalter, a Professional Corporation, at 10:00 a.m. Pacific time (the “Closing Date”). On or before the Closing Date, UAB and HBC will file, or cause to be filed, with the DBO and the California Secretary of State an agreement of merger in substantially the form of Annex F to this Agreement. The Merger shall become effective at the time that such agreement of merger has been filed with the DBO as provided in Section 4887(c) of the CFC (the “Effective Time”).

Section 1.03 Effect of the Merger. Upon the consummation of the Merger, the separate corporate existence of UAB shall cease and HBC shall continue as the surviving entity under the laws of the State of California. The name of Heritage Bank of Commerce as the surviving entity of the Merger shall remain “Heritage Bank of Commerce.” From and after the Effective Time, HBC, as the surviving entity of the Merger, shall possess all of the properties and rights and be subject to all of the liabilities and obligations of UAB.

Section 1.04 Articles of Incorporation; By-laws. 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.

Section 1.05 Directors and Executive Officers. All the directors and officers of HCC and HBC immediately prior to the Effective Time shall be the directors of HCC and HBC after the Merger, in each case until their respective successors are duly elected or appointed and qualified.

Section 1.06 Possible Alternative Structures. Notwithstanding anything to the contrary contained in this Agreement, prior to the Effective Time HCC shall be entitled, after consultation with UAB, to revise the structure of effecting the acquisition of UAB, provided, however, that (a) there are no adverse federal or state income tax consequences to UAB’s shareholders as a result of the modification (including no impact upon the opinions of counsel related to tax matters to be delivered pursuant to this Agreement), (b) the consideration to be paid to the

holders of UAB Common Stock and UAB Preferred Stock under this Agreement is not thereby changed in kind, value or reduced in amount and the delivery of such consideration will not be delayed, (c) the benefits to be received by UAB’s directors, officers and employees under this Agreement are not diminished, and (d) such modification will not delay materially or jeopardize the receipt of any regulatory approvals or other consents and approvals relating to the consummation of the Merger or otherwise cause any condition to Closing set forth in Article VI not to be capable of being fulfilled. The parties agree to appropriately amend this Agreement and any related documents in order to reflect any such revised structure.

Section 1.07 Additional Actions. If at any time after the Effective Time the Surviving Corporation shall consider or be advised that any deeds, bills of sale, assignments or assurances or any other acts or things are necessary, desirable or proper (a) to vest, perfect or confirm, of record or otherwise, in the Surviving Corporation its right, title or interest in or to or under any of the rights, privileges, powers, franchises, properties or assets of UAB, or (b) otherwise to carry out the purposes of this Agreement, the Surviving Corporation and its proper officers and directors or their designees shall be authorized to execute and deliver, in the name and on behalf of UAB all such deeds, bills of sale, assignments and assurances and to do, in the name and on behalf of UAB, all such other acts and things as may be necessary, desirable or proper to vest, perfect or confirm the Surviving Corporation’s right, title or interest in or to or under any of the rights, privileges, powers, franchises, properties or assets of UAB and otherwise to carry out the purposes of this Agreement.

ARTICLE II
EFFECT OF THE MERGER ON CAPITAL STOCK

Section 2.01 Effect of the Merger on Capital Stock. At the Effective Time, as a result of the Merger and without any action on the part of HCC, HBC or UAB or the holder of any capital stock of HCC, HBC or UAB:

(a) Cancellation of Certain UAB Common Stock. Each share of UAB Common Stock that is owned by HCC or UAB (as treasury stock or otherwise) or any of their respective direct or indirect wholly-owned subsidiaries will automatically be cancelled and retired and will cease to exist, and no consideration will be delivered in exchange therefor.

(b) HCC Capital Stock. Each share of HCC Common Stock issued and outstanding immediately prior to the Effective Time, shall remain issued and outstanding and shall not be affected by the Merger.

(c) HBC Capital Stock. Each share of HBC common stock, no par value, issued and outstanding immediately prior to the Effective Time shall remain issued and outstanding and shall not be affected by the Merger.

(d) Conversion of UAB Common Stock and Preferred Stock.

(i) Each share of UAB Common Stock issued and outstanding immediately prior to the Effective Time (other than shares to be cancelled and retired in accordance with Section 2.01(a), and (ii) Dissenting Shares) shall, by virtue of the Merger, be converted into the right to receive 2.1644 (the “Per Share Exchange Ratio”) shares of HCC Common Stock, together with any cash in lieu of fractional shares as specified in Section 2.01(g).

(ii) Each share of Series D Preferred issued and outstanding immediately prior to the Effective Time shall, by virtue of the Merger, be converted into the right to receive the number of shares of HCC Common Stock equal to the product of (A) the Per Share Exchange Ratio multiplied by (B) the number of Series D Common Equivalent Shares underlying each such share of Series D Preferred, together with cash in lieu of fractional shares as specified in Section 2.01(g).

(iii) Each share of Series E Preferred issued and outstanding immediately prior to the Effective Time shall, by virtue of the Merger, be converted into the right to receive the number of shares of HCC Common Stock equal to the product of (A) the Per Share Exchange Ratio multiplied by (B) the number of Series E Common Equivalent Shares underlying each such share of Series E Preferred, together with cash in lieu of fractional shares as specified in Section 2.01(g).

(iv) Each share of UAB Series A Preferred Stock issued and outstanding immediately prior to the Effective Time shall, by virtue of the Merger, be converted into the right to receive $1,000 in cash per share.

(v) Each share of UAB Series B Preferred Stock issued and outstanding immediately prior to the Effective Time shall, by virtue of the Merger, be converted into the right to receive $1,000 in cash per share.

For purposes of this Agreement, the Per Share Exchange Ratio together with cash, and cash in lieu of fractional shares provided in clauses (i) through (v) is referred to as the “Merger Consideration.”

(e) Dilution. If HCC changes (or the HCC Board sets a related record date that will occur before the Effective Time for a change in) the number or kind of shares of HCC Common Stock outstanding by way of a stock split, stock dividend, recapitalization, reclassification, reorganization or similar transaction, then the Per Share Exchange Ratio will be adjusted proportionately to account for such change to give the holders of UAB Common Stock, Series D Preferred Stock and Series E Preferred Stock the same economic effect contemplated by this Agreement prior to such change.

(f) Cancellation of Shares and Closing of UAB’s Transfer Books. At the Effective Time (i) none of the shares of UAB Common Stock or UAB Preferred Stock shall be outstanding and shall automatically be cancelled and shall cease to exist, and each holder of a valid certificate (each a “Certificate”) previously representing any such shares of UAB Common Stock or UAB Preferred Stock or owner designated by a book entry previously representing a non-certificated share of UAB Common Stock or UAB Preferred Stock (a “Book-Entry Share”) shall thereafter cease to have any rights with respect to such securities, except the right to receive (i) the Merger Consideration, (ii) any dividends and other distributions in accordance with Section 2.03(e), and (iii) any cash to be paid in lieu of any fractional share of HCC Common Stock in accordance with Section 2.01(g). The stock transfer books of UAB shall be closed with

respect to all shares of UAB Common Stock and UAB Preferred Stock outstanding immediately prior to the Effective Time, and no further transfer of any such shares of UAB Common Stock or UAB Preferred Stock shall be made on such stock transfer books after the Effective Time. If, after the Effective Time, UAB Certificates or Book-Entry Shares representing such shares of UAB Common Stock or UAB Preferred Stock are presented for transfer to the Exchange Agent or to the Surviving Corporation or HCC, they shall be cancelled and shall be exchanged as provided in Section 2.03.

(g) No Fractional Shares. No fractional shares of HCC Common Stock shall be issued in connection with the Merger, and no certificates or scrip for any such fractional shares shall be issued upon the surrender for exchange of Certificates or Book-Entry Shares. Any holder of UAB Common Stock, Series D Preferred or Series E Preferred who would otherwise be entitled to receive a fraction of a share of HCC Common Stock (after aggregating all fractional shares of HCC Common Stock issuable to such holder), in lieu of such fraction of a share and, upon surrender of such holder’s Certificates or Book-Entry Shares to the Exchange Agent, shall be paid in cash the dollar amount (rounded to the nearest whole cent), without interest, determined by multiplying such fraction of a share of HCC Common Stock multiplied by the HCC Average Closing Price.

Section 2.02 Exchange Agent; Deposit of Merger Consideration. Prior to the Closing Date, HCC shall select a bank or trust company to act as exchange agent in the Merger (the “Exchange Agent”) and provide the Exchange Agent with appropriate instructions regarding the matters described in this Article II in form and substance reasonably acceptable to HCC and UAB, all in accordance with the provisions of an agreement executed between HCC and the Exchange Agent. HCC shall deposit, or cause to be deposited, with the Exchange Agent (by instruction to HCC’s transfer agent) prior to the Effective Time (a) certificates representing the shares of HCC Common Stock issuable pursuant to Section 2.01(d)(i), (ii) and (iii) (or make appropriate alternative arrangements if uncertificated shares of HCC Common Stock represented by a book entry will be issued), (b) cash sufficient for the amounts payable pursuant to Section 2.01(d)(iv) and (v), and (c) cash sufficient in lieu of fractional shares to be paid in accordance with Section 2.01(g). The shares of HCC Common Stock and cash amounts so deposited with the Exchange Agent are referred to collectively as the “Exchange Fund.”

Section 2.03 Exchange of Certificates and Book-Entry Shares.

(a) HCC shall take all steps necessary to cause the Exchange Agent, not later than five (5) business days after the Effective Time, to mail to holders of UAB Common Stock and UAB Preferred Stock of record immediately prior to the Effective Time (i) a letter of transmittal in a customary form that is reasonably acceptable to UAB (“Letter of Transmittal”), and (ii) instructions for use in effecting the surrender of such holder’s Certificates and Book-Entry Shares in exchange for the Merger Consideration in exchange therefore.

(b) Upon surrender of a Certificate or Book-Entry Share to the Exchange Agent for exchange, together with a properly completed Letter of Transmittal and such other documents as may be reasonably required by the Exchange Agent or HCC, the holder of such Certificate or Book-Entry Share shall be entitled to receive in exchange therefor (i) a certificate representing the number of whole shares of HCC Common Stock (or uncertificated shares of HCC Common

Stock represented by a book entry) to which such holders of UAB Common Stock and UAB Preferred Stock, Series D Preferred and Series E Preferred shall have become entitled in accordance with Section 2.01(d)(i), (ii) and (iii), (ii) a check representing the amount of cash payable pursuant to Section 2.01(d)(iv) and (v), and (iii) a check representing the amount of cash in lieu of any fractional share of HCC Common Stock, if any, which such holder has the right to receive in respect of the Certificate or Book-Entry Share surrendered pursuant to Section 2.01(g). No interest will be paid or accrued on the cash in lieu of fractional shares. The Certificates or Book-Entry Shares so surrendered shall be canceled.

(c) If any Certificate shall have been lost, stolen, or destroyed, HCC or the Exchange Agent may in its sole discretion require the owner of such lost, stolen, or destroyed Certificate to make and deliver to HCC or the Exchange Agent an affidavit of that fact and an agreement in customary form that is reasonably satisfactory to HCC indemnifying HCC and the Surviving Corporation against any claim that may be made against HCC or the Surviving Corporation and to deliver a bond (in such sum as HCC or the Exchange Agent may reasonably direct) as indemnity against any claim that may be made against the Exchange Agent, HCC, or the Surviving Corporation with respect to such Certificate.

(d) If any portion of the HCC Common Stock that a person has the right to receive pursuant to the provisions of Section 2.01(d) is to be issued in a name other than that in which the Certificate or Book-Entry Share surrendered is registered, it shall be a condition to such issuance thereof that the Certificate or Book-Entry Shares surrendered shall be properly endorsed (or accompanied by an appropriate instrument of transfer) and otherwise in proper form for transfer, and the person requesting such exchange shall pay to the Exchange Agent in advance any transfer or other Tax required by reason of a certificate or uncertificated book entry share, as applicable, or establish to the reasonable satisfaction of the Exchange Agent that such Tax has been paid or is not payable.

(e) No dividends or other distributions declared after the Effective Time with respect to HCC Common Stock and payable to the holders of record thereof shall be paid to the holder of any unsurrendered Certificate or Book-Entry Share until the holder thereof shall surrender such Certificate or Book-Entry Share in accordance with this Article II. After the surrender of a Certificate or Book-Entry Share in accordance with this Article II, the record holder thereof shall be entitled to receive any such dividends or other distributions, without any interest thereon, which theretofore had become payable with respect to shares of HCC Common Stock represented by such Certificate or Book-Entry Share.

(f) Any portion of the Exchange Fund that remains undistributed to holders of Certificates or Book-Entry Shares as of the date twelve (12) months after the Effective Time shall be delivered to HCC upon demand, and any holders of Certificates or Book-Entry Shares who have not theretofore surrendered their Certificates or Book-Entry Shares in accordance with this Section 2.03 shall thereafter look only to HCC for satisfaction of their claims for the Merger Consideration, and any dividends or distributions with respect to HCC Common Stock, in each case without interest thereon. Notwithstanding the foregoing, none of HCC, the Surviving Corporation, ATB, UAB or the Exchange Agent or any other person shall be liable to any former holder of shares of UAB Common Stock for any amount properly delivered to a public official pursuant to applicable abandoned property, escheat or similar Law. HCC and HBC shall be

entitled to rely upon the stock transfer books of UAB to establish the identity of those persons entitled to receive merger consideration specified in this Agreement, which books shall be conclusive with respect thereto. In the event of a dispute with respect to ownership of stock represented by any Certificate, HCC and HBC shall be entitled to deposit the Merger Consideration in respect thereof in escrow with an independent third party and thereafter be relieved with respect to any claims thereto.

(g) Each of the Exchange Agent, HCC, and HBC shall be entitled to deduct and withhold from any consideration payable or otherwise deliverable pursuant to this Agreement to any holder or former holder of UAB Common Stock or UAB Preferred Stock such amounts as may be required to be deducted or withheld therefrom under the Code or any provision of state, local, or foreign Tax law or under any other applicable Law. To the extent such amounts are so deducted or withheld, such amounts shall be treated for all purposes under this Agreement as having been paid to the person to whom such amounts would otherwise have been paid.

(h) Any portion of the HCC Common Stock made available to the Exchange Agent in respect of any Dissenting Shares shall be returned to HCC upon demand.

Section 2.04 Dissenting Shares. Notwithstanding any provision of this Agreement to the contrary, shares of UAB Common Stock that are outstanding immediately prior to the Effective Time and that are held by a shareholder who is entitled to demand, and who properly demands, the fair market value of such shares pursuant to, and who complies in all respects with, Chapter 13 of the CGCL (a “Dissenting Shareholder”) shall not be converted into the right to receive the Merger Consideration. For purposes of this Agreement, “Dissenting Shares” means any shares of UAB Common Stock as to which a Dissenting Shareholder has properly exercised a demand for fair market value pursuant to Chapter 13 of the CGCL. At the Effective Time all Dissenting Shares shall be cancelled and retired and shall cease to exist. No Dissenting Shareholder shall be entitled to any Merger Consideration in respect of any Dissenting Shares unless and until such holder shall have failed to perfect or shall have effectively withdrawn or lost such holder’s right to demand fair market value of its Dissenting Shares under the CGCL, and any Dissenting Shareholder shall be entitled to receive only the payment provided by Chapter 13 of the CGCL with respect to the Dissenting Shares owned by such Dissenting Shareholder and not any Merger Consideration. UAB shall give HCC (a) prompt notice of any written demands for fair market value, attempted withdrawals of such demands and any other instruments served pursuant to applicable Law relating to shareholders’ demands for fair market value, and (b) the opportunity to direct all negotiations and proceedings with respect to demands for fair market value under the CGCL. UAB shall not, except with the prior written consent of HCC, voluntarily make any payment with respect to any demands for fair market value of Dissenting Shares, offer to settle or settle any such demands.

Section 2.05 Intended Tax Treatment. It is intended that the Merger shall constitute a “reorganization” as that term is used in Section 368(a) of the Code (“Reorganization”), and that this Agreement shall constitute a “plan of reorganization” as that term is used in Sections 354 and 361 of the Internal Revenue Code of 1986, as amended (the “Code”). Until the Closing, each party hereto shall use all commercially reasonable efforts to cause the Merger to so qualify, and will not knowingly take any action, cause any action to be taken, fail to take any action or cause any action to fail to be taken which action or failure to act could prevent the Merger from qualifying as a Reorganization.

ATB and UAB shall not be required to provide access to or disclose information where such access or disclosure would jeopardize the protection of attorney-client privilege or contravene any applicable Law, agreement or fiduciary duty, or violate the rights, interests or confidence of any customer (it being agreed that the parties shall use their reasonable commercial efforts to cause such information to be provided in a manner that would not result in such jeopardy or contravention). No investigation shall affect UAB’s or ATB’s representations and warranties contained herein, or limit or otherwise affect the remedies available to HCC pursuant to this Agreement.

(b) HCC and UAB shall, and cause their respective Representatives to, comply with all of their respective obligations under the Confidentiality Agreements, which shall survive the termination of this Agreement in accordance with the terms set forth therein.

Without limiting the generality of the foregoing, ATB and UAB acknowledge and agree that any violation of or the taking of any action inconsistent with any of the restrictions set forth in the preceding sentence by any Representative of ATB or UAB, whether or not such Representative is purporting to act on behalf of UAB, shall be deemed to constitute a breach of this Section 6.04 by UAB or ATB, as applicable.

(b) Prior to the adoption of this Agreement by the Requisite UAB Vote, Section 6.04(a) shall not prohibit UAB from furnishing nonpublic information regarding UAB to or entering into negotiations or discussions with any person in response to a bona fide, unsolicited written Acquisition Proposal that the UAB Board concludes in good faith (after consultation with its financial advisor and its outside legal counsel) constitutes a Superior Proposal that is submitted to UAB by such person (and not withdrawn prior to the furnishing of

such information or such discussions) if (i) neither UAB nor any Representative of UAB shall have violated any of the restrictions set forth in Section 6.04(b), (ii) the UAB Board concludes in good faith, after having obtained and taken into account the advice of its outside legal counsel, that such action is required in order for the UAB Board to comply with its fiduciary obligations to UAB’s shareholders under applicable Law, (iii) prior to furnishing any such nonpublic information to or entering into discussions with such person UAB gives HCC written notice of UAB’s intention to furnish nonpublic information to or enter into discussions with such person, and UAB receives from such person an executed Acceptable Confidentiality Agreement, and (iv) upon furnishing any such nonpublic information to such person UAB furnishes such nonpublic information to HCC (to the extent such nonpublic information has not been previously furnished by UAB to HCC).

(c) UAB or ATB, as appropriate, shall notify HCC promptly (but in no event later than twenty-four hours after receipt of (i) any inquiry or indication of interest that may lead to an Acquisition Proposal, (ii) an Acquisition Proposal (including or any modification of or an amendment to any Acquisition Proposal), or (iii) any request for nonpublic information relating to UAB (including access to the properties, books or records of UAB) by any person that has made, or to the knowledge of ATB or UAB, may be considering making, an Acquisition Proposal. Such notice to HCC shall be made orally and in writing, and shall indicate the identity of the person submitting any of the foregoing, and the terms of any such Acquisition Proposal (or modification or amendment), inquiry, indication or request. UAB or ATB shall keep HCC fully informed on a current basis of any additional information requested or provided by UAB and any changes in the status and any changes or modifications in the terms of any such Acquisition Proposal, inquiry, indication or request.

(d) ATB and UAB shall instruct and cause its Representatives to, immediately cease and terminate any existing activities, discussions or negotiations with any persons (other than HCC) conducted prior to the date of this Agreement with respect to the possibility or consideration of any Acquisition Proposal.

ATB and UAB has cancelled access to any third party which has been granted access to any virtual or other data room maintained by or on behalf of ATB or UAB other than HCC, HBC and its Representatives.

(e) Neither ATB nor UAB shall not (i) release any person from and agrees to take all commercially reasonable efforts to enforce the confidentiality, standstill non-solicitation or similar provisions of any agreement to which ATB or UAB is a party with respect to an Acquisition Proposal that remains in effect as of the date of this Agreement, and (ii) shall immediately take all steps necessary to terminate any approval that may have been given prior to the date of this Agreement under any such provisions authorizing any person to make an Acquisition Proposal.

(f) ATB and UAB acknowledge that this Section 6.04 is a significant inducement for HCC and HBC to enter into this Agreement and the absence of such provision would have resulted in either (i) a material reduction in the consideration to be paid to shareholders of UAB in the Merger, or (ii) a failure to induce HCC and HBC to enter into this Agreement.

Section 6.05 Registration Statement; Proxy Statement/Prospectus; NASDAQ Listing.

(a) As promptly as practicable, by in any event no later than forty-five (45) days from the date of this Agreement, UAB and HCC shall jointly cause the Registration Statement to be prepared, and HCC shall cause the Registration Statement (in which the Proxy Statement/Prospectus will be included with respect to the issuance of HCC Common Stock in the Merger) to be filed with the SEC. UAB and HCC shall each timely furnish all information concerning it and the holders of its capital stock as the other may reasonably request in connection with the preparation of the Registration Statement (including the Proxy Statement/Prospectus) and any amendment or supplement thereto. HCC and UAB shall each use their respective reasonable commercial efforts to cause the Registration Statement and Proxy Statement/Prospectus to comply with the rules and regulations promulgated by the SEC, to respond timely to any comments of the SEC or its staff, and to have the Registration Statement declared effective under the Securities Act as reasonably as practicable after it is filed with the SEC. HCC and UAB shall notify each other timely of the receipt of any comments from the SEC or its staff and of any request by the SEC or its staff for amendments or supplements to Registration Statement or for additional information and shall supply each other with copies of all correspondence between such party or any of its Representatives, on the one hand, and the SEC or its staff, on the other hand, with respect to Registration Statement or the Merger. HCC shall also file and use reasonable commercial efforts to cause to become effective as promptly as possible any amendment to the Registration Statement, including the Proxy Statement/Prospectus and, if required, UAB shall mail to its shareholders any such amendment that becomes necessary after the date the Registration Statement is declared effective. If at any time prior to the Effective Time either UAB or HCC becomes aware of any event or circumstance which is required to be set forth in an amendment or supplement to the Registration Statement or Proxy Statement/Prospectus, it shall promptly inform the other party. Each of HCC and UAB will advise the other, promptly after it receives notice thereof, of the time when the Registration Statement has become effective or any supplement or amendment thereto has been filed, the issuance of any stop order, or any request by the staff of the SEC for amendment of the Registration Statement or Proxy Statement/Prospectus or comments thereon or responses thereto.

(b) Each of HCC and UAB shall use reasonable commercial efforts to cause all documents that it is responsible for filing with the SEC in connection with the Contemplated Transactions to comply as to form and substance in all material respects with the applicable requirements of the Securities Act and the Exchange Act, as applicable.

(c) Prior to the Effective Time, HCC shall use reasonable commercial efforts to qualify the HCC Common Stock under the securities or the “blue sky” laws of such jurisdictions as may be required; provided, however, that HCC shall not be required to (i) qualify to do business as a foreign corporation in any jurisdiction in which it is not now so qualified, (ii) file a general consent to service of process in any jurisdiction, or (iii) subject itself to taxation in any jurisdiction in which it is not so subject.

Section 6.06 UAB Shareholder Meeting.

(a) UAB shall take all action necessary and appropriate and in accordance with applicable Law and its Charter Documents to duly call, give notice of, convene and, as soon as practicable but not later than forty-five (45) days after the Registration Statement is declared effective, hold the UAB Meeting and, take such other actions necessary to obtain the relevant shareholder approvals for the purpose of obtaining the Requisite UAB Vote. UAB (in consultation with HCC) shall set a single date for persons entitled to notice of and to vote at the UAB Meeting.

(b) Subject to Section 6.06(d) and (e), the UAB Board shall at all times prior to and during the UAB Meeting recommend approval of this Agreement and the Merger and shall use its reasonable best efforts to solicit such approval by its shareholders (the “UAB Board Recommendation”). Without limiting the generality of the foregoing, unless this Agreement has terminated in accordance with Section 8.01, this Agreement and the Merger shall be submitted to the shareholders of UAB at the UAB Meeting whether or not (i) the UAB Board shall have effected an Change of Recommendation or (ii) any Acquisition Proposal shall have been publicly proposed or announced or otherwise submitted to UAB or any of its advisors. In addition to the foregoing, UAB shall not submit to the vote of its shareholders at or prior to the UAB Meeting any proposal (including an Acquisition Proposal) other than the Merger without the approval of HCC.

(c) UAB shall cooperate and keep HCC informed on a reasonably current basis regarding its solicitation efforts and voting results following the dissemination of the Proxy Statement/Prospectus to the shareholders of UAB. HCC may, after consultation with UAB, require UAB to adjourn, delay or postpone the UAB Meeting once for a period not to exceed thirty (30) days (but prior to the date that is two (2) business days prior to the End Date) to solicit additional proxies necessary to obtain the Requisite UAB Vote. UAB shall not, without the prior written consent of HCC, adjourn or postpone the UAB Meeting; provided, however, that UAB may, without the prior written consent of HCC, adjourn or postpone the UAB Meeting (i) if on the date initially scheduled for the UAB, UAB notifies HCC that it has not received proxies representing a sufficient number of shares of UAB Common Stock to obtain the Requisite UAB Vote, UAB shall adjourn the UAB Meeting until such date as shall be mutually agreed upon by UAB and HCC, which date shall not be less than five (5) business days nor more than ten (10) business days after the date of adjournment, and subject to the terms and conditions of this Agreement shall continue to use all reasonable best efforts, together with its proxy solicitor, to assist in the solicitation of proxies from shareholders relating to the Requisite UAB Vote, or (ii) after consultation with HCC, if the failure to adjourn or postpone the UAB Meeting would reasonably be expected to be a violation of applicable Law for the distribution of any required supplement or amendment to the Proxy Statement. Once UAB has established the record date for determining shareholders of UAB entitled to vote at the UAB Meeting, UAB shall not change such record date or establish a different record date for the UAB Meeting without the prior written consent of HCC, unless required to do so by applicable Law or the UAB Charter

Documents. During any such period of adjournment, delay or postponement, UAB shall continue in all respects to comply with its obligations under this Section 6.06 and, shall in good faith use reasonable best efforts (including engaging a proxy solicitor) to obtain the Requisite UAB Vote.

(d) Subject to Section 6.06(e), neither the UAB Board nor any committee thereof shall (i) withdraw, modify, amend or qualify the UAB Board Recommendation in a manner adverse to HCC (it being understood that the failure of the UAB Board Recommendation to be unanimous shall constitute a withdrawal, modification, amendment or qualification that is adverse to HCC), (ii) adopt a resolution to withdraw, amend or qualify the UAB Board Recommendation in a manner adverse to HCC, (iii) take any other action that is or becomes disclosed publicly and which can reasonably be interpreted to indicate that the UAB Board or any committee thereof does not support the Merger and this Agreement or does not believe that the Merger and this Agreement are in the best interests of UAB’s shareholders (it being understood that taking a neutral position or no position with respect to any Acquisition Proposal shall constitute an adverse modification), (iv) publicly announce its intention to withdraw, modify, amend or qualify the UAB Board Recommendation in a manner adverse to HCC, (v) fail to reaffirm without qualification the UAB Board Recommendation, or fail to state publicly without qualification that the Merger and this Agreement are in the best interests of UAB’s shareholders, within five (5) business days after HCC requests in writing that such action be taken, (vi) fail to announce publicly, within ten (10) business days after a tender offer or exchange offer relating to securities of UAB shall have been commenced, that the UAB Board recommends rejection of such tender or exchange offer, (vii) fail to issue, within ten (10) business days after an Acquisition Proposal is publicly announced, a press release announcing its opposition to such Acquisition Proposal, (viii) approve, endorse, or recommend any Acquisition Proposal, or (ix) resolve or propose to take any action described in clauses (i) through (viii) of this sentence (each of the foregoing actions described in clauses (i) through (viii) of this sentence being referred to as a “Change in Recommendation”).

(e) Notwithstanding anything to the contrary in Section 6.06(d), at any time prior to, but not after obtaining the Requisite UAB Vote, the UAB Board may effect a Change of Recommendation or terminate this Agreement pursuant to Section 8.01(h), if (i) UAB has not breached its obligations under Section 6.04 and 6.06(a), (b) and (c) and is not otherwise in material breach of this Agreement, (ii) UAB receives an unsolicited bona fide, written Acquisition Proposal from any person that is not withdrawn, and (iii) (A) a majority of the entire UAB Board determines in good faith, (after consultation with its independent financial advisors and outside legal counsel), that such Acquisition Proposal constitutes a Superior Proposal and after consultation with its outside legal counsel, that the failure of the UAB Board to take such action on the Acquisition Proposal would or would more likely than not result in a violation of its fiduciary duties to the shareholders of UAB under applicable Law, and (B) (1) UAB provides HCC prior written notice at least three (3) business days (or such longer period as it may be extended upon the modification or amendment of the Acquisition Proposal as contemplated below) (“Notice of Superior Proposal”) prior to taking such action, which notice shall state that the UAB Board has received a Superior Proposal and, absent any revision to the terms and conditions of this Agreement, the UAB Board has resolved to effect a Change of Recommendation or to terminate this Agreement pursuant to Section 8.01(h), as applicable, which notice include a copy of the proposed agreement or agreements to effect the Superior

Proposal and the identity of the person making the Superior Proposal (it being understood that the Notice of Superior Proposal shall not in and of itself be deemed a Change of Recommendation or termination); (2) during such three (3) business day period (as it may be extended upon the modification or amendment of the Acquisition Proposal as contemplated below), UAB negotiates in good faith (including by making its officers, directors and its financial and legal advisors reasonably available to negotiate) with HCC (to the extent that HCC wishes to negotiate) to enable HCC to make an improved offer that is favorable to the shareholders of UAB so that such Acquisition Proposal would cease to constitute a Superior Proposal; and (3) at the end of such three (3) business day period (as it may be extended upon the modification or amendment of the Acquisition Proposal as contemplated below, or such earlier time that HCC advises UAB in writing that it no longer wishes to negotiate to amend this Agreement), a majority of the entire UAB Board, after taking into account any modifications to the terms of this Agreement and the Merger agreed to by HCC after receipt of the Notice of Superior Proposal, continues to believe (after consultation with its independent financial advisors and outside legal counsel) that such Acquisition Proposal constitutes a Superior Proposal and, after consultation with its outside legal counsel, that the failure to accept the Acquisition Proposal would or would more likely than not result in a violation of its fiduciary duties to the shareholders of UAB under applicable Law. In the event of any revisions to the terms of an Acquisition Proposal that are material to such Acquisition Proposal and made after the start of the three (3) business day period of clause (iii)(B)(1), such revisions shall be deemed a new Acquisition Proposal and UAB shall be required to deliver a new written notice as required by clause (iii)(B)(1) to HCC and to comply with the requirements of this Section 6.06(e) with respect to such new Acquisition Proposal.

(f) Nothing in Section 6.06(e) shall be interpreted to excuse UAB and the UAB Board from complying with its unqualified obligation to submit this Agreement to its shareholders at the UAB Meeting and UAB shall not submit to the vote of its shareholders at or prior to the UAB Meeting any Acquisition Proposal other than the Merger. Without limiting the foregoing, if the UAB Board has withdrawn or modified the UAB Board Recommendation as permitted by Section 6.06(e), then, unless this Agreement has been terminated in accordance with Section 8.01, the UAB Board shall submit this Agreement to UAB’s shareholders without recommendation (although the resolutions adopting this Agreement as of the date of this Agreement may not be rescinded or amended), in which event the UAB Board may communicate the basis for its lack of a recommendation to UAB’s shareholders in Proxy Statement/Prospectus or an appropriate amendment or supplement thereto to the extent required by applicable Law.

Section 6.07 Approvals.

(a) Upon the terms and subject to the conditions set forth in this Agreement (including those contained in this Section 6.07), each of HCC, HBC and UAB shall use its reasonable best efforts to take or cause to be taken all actions, and to do or cause to be done, and to assist and cooperate with the other parties in doing, all things necessary, proper or advisable to consummate and make effective, and to satisfy all conditions to the Contemplated Transactions, including (i) obtaining all necessary Governmental Authorizations, and the making all necessary registrations and filings (including filings with Governmental Entities, which shall be made within forty-five (45) days of the date of this Agreement) and the taking of all steps as may be

necessary or advisable to obtain an approval or waiver from or to avoid an action or proceeding by any Governmental Entity, (ii) obtaining all necessary consents or waivers from or providing notice to third parties (including actions required in order to continue any UAB Material Contract (including any Contract entered into following the date of this Agreement that would have been a UAB Material Contract at the time this Agreement was entered into) following the Closing or to avoid any penalty or other fee under such UAB Material Contract, in each case arising in connection with the Contemplated Transactions, and (iii) the execution and delivery of any additional instruments necessary to consummate the Merger and to fully carry out the purposes of this Agreement. Subject to applicable Law, UAB and HCC shall promptly cooperate and coordinate with the other in the taking of the actions contemplated by clauses (i), (ii) and (iii) immediately above and supply the other with any information that may be reasonably required in order to effectuate the taking of such actions. Each party hereto shall promptly inform the other party of any communication from any Governmental Entity regarding any of the Contemplated Transactions, except to the extent prohibited by applicable Laws related to the exchange of information. If UAB or HCC receives a request for additional information or documentary material from any Governmental Entity with respect to Contemplated Transactions, then it shall use reasonable commercial efforts to make, or cause to be made, as soon as reasonably practicable and after consultation with the other party, an appropriate response in compliance with such request. Neither HCC, HBC nor UAB shall commit to or agree with any Governmental Entity to stay, toll or extend any applicable waiting period under any applicable Law without the prior written consent of the other. In the event that any party shall fail to obtain any such third party consent as required in clause (ii), that party shall use reasonable commercial efforts, and shall take any such actions reasonably requested by the other party, to minimize any adverse effect on the consummation of the Merger on the Surviving Corporation businesses and financial condition resulting, or that would be reasonably likely to result after the Effective Time, from the failure to obtain such consent.

(b) Subject to applicable Law relating to the exchange of information, HCC and UAB shall upon request furnish each other with all information concerning HCC, HBC, UAB and their respective directors, officers and shareholders and such other matters as may be reasonably necessary in connection with any statement, filing, notice or application made by or on behalf of HCC, HBC, or UAB to any Governmental Entity in connection with the Contemplated Transactions. HCC and UAB shall have the right to review in advance and, to the extent practicable, each will consult the other on, in each case subject to applicable Law relating to the exchange of information, any filing made or proposed to be made with, or written materials submitted or proposed to be submitted to, any third party or any Governmental Entity in connection with the Contemplated Transactions.

(c) Notwithstanding anything set forth in this Agreement, under no circumstances shall HCC, HBC or UAB be required, and any other party be permitted (without the other parties’ written consent in its sole discretion), to take any action or commit to take any action, or agree to any condition, restriction or requirement, involving any of them pursuant to this Section 6.07 or otherwise in connection with obtaining the foregoing Government Authorizations, that would, or would be reasonably likely to, individually or in the aggregate, materially reduce the financial benefits of the Merger to such a degree that HCC, HBC or UAB, as applicable would not have entered into this Agreement had such conditions, restrictions or requirements been known at the date of this Agreement (a “Burdensome Condition”); provided,

however, that if requested by HCC, then UAB will take or commit to take any such action, or agree to any such condition or restriction, so long as such action, commitment, agreement, condition or restriction is binding on UAB only in the event the Closing occurs and, provided further, that such action, commitment, agreement, condition or restriction (i) does not create an adverse federal or state income tax consequences to UAB’s shareholders (including no impact upon the opinions of counsel related to tax matters to be delivered pursuant to this Agreement), (ii) does not change the kind, amount or the consideration to be paid to the holders of UAB Shares under this Agreement, or the delay the delivery of such consideration, (iii) does not diminish the benefits to be received by UAB’s directors, officers and employees under this Agreement, any UAB Plan or Contract to which UAB is a party and (iv) does not delay materially or jeopardize the receipt of any regulatory approvals or other consents and approvals relating to the consummation of the Merger or otherwise cause any condition to Closing set forth in Article VI not to be capable of being fulfilled.

(d) Subject to applicable Law (including applicable Law relating to the exchange of information), UAB and HCC shall keep each other apprised of the status of matters relating to the completion of the Contemplated Transactions. Without limiting the generality of the foregoing (i) each of HCC, HBC and UAB shall timely furnish the other with copies of notices or other communications received by it (or written summaries of communications received orally), from any third party or Governmental Entity with respect to the Contemplated Transactions, (ii) each of HCC, HBC and UAB shall provide the other a reasonable opportunity to review in advance, and to the extent practicable accept the reasonable comments of the other in connection with any proposed non-confidential written communication to, including any filings with, any Governmental Entity, and (iii) UAB and HCC shall consider in good faith the other party’s views with respect to and confer in good faith with each other to resolve any disagreement as to strategy with respect to any communication by UAB, HCC or HBC with any Governmental Entity or third party relating to the Contemplated Transactions.

(e) In the event that any Legal Action is instituted (or threatened to be instituted) by a Governmental Entity challenging the Contemplated Transactions, UAB and HCC shall cooperate in all respects with each other and each of UAB and HCC shall use its reasonable commercial efforts to contest and resist any such Legal Action and to have vacated, lifted, reversed or overturned any Order, whether temporary, preliminary or permanent, that is in effect and that prohibits, prevents or restricts consummation of the Contemplated Transactions.

(a) HCC and HBC shall have the right but not the obligation to offer employment immediately following the Effective Time to any and all persons who are UAB employees immediately before the Effective Time (employees of UAB who will be employed by HCC or HBC are referred to as “Continuing Employees”). UAB will provide HCC with information regarding such persons’ current employment arrangements with UAB and will otherwise assist HCC and HBC in making such offers. Continuing Employees shall be offered salary or wage levels at least equal to the salary or wage levels to which such employees were entitled to immediately prior to the Closing Date. Subject to the provisions of this Section 6.11, as soon as administratively practicable after the Effective Time, HCC shall take all reasonable action so that Continuing Employees shall be entitled to participate in each employee benefit plan, program or arrangement of HCC and HBC of general applicability (the “HCC Benefit Plans”) to the same

extent as similarly-situated employees of HCC and HBC (it being understood that inclusion of Continuing Employees in HCC Benefit Plans may occur at different times with respect to different plans), provided, however, that coverage shall be continued under corresponding benefit plans of UAB (to the extent such UAB plans have not been terminated) until such employees are permitted to participate in the HCC Benefit Plans and, provided further, that Continuing Employees shall not have the opportunity to participate in the HBC 2005 Amended and Restated Supplemental Executive Retirement Plan (“SERP”). Accordingly, HCC and HBC shall use reasonable efforts to ensure that from the Closing Date through the next open enrollment date for a HCC or HBC group health, dental, and vision, Continuing Employees shall continue to be covered by UAB’s group health, dental, and vision.

(b) To the extent that a Continuing Employee becomes eligible to participate in an employee benefit plan maintained by HCC or HBC, HCC or HBC, as applicable, shall cause such employee benefit plan to recognize the service of such Continuing Employee with UAB for purposes of eligibility, participation, vesting and benefit accrual under such employee benefit plan of HCC or HBC, to the same extent that such service was recognized immediately prior to the Effective Time under a corresponding UAB Benefit Plan in which such Continuing Employee was eligible to participate immediately prior to the Effective Time; provided, however, that such recognition of service shall not (i) operate to duplicate any benefits of a Continuing Employee with respect to the same period of service, (ii) apply for purposes of any retiree medical plans, (iii) apply for purposes of the HCC Employee Stock Ownership Plan, (iv) apply for any benefit accrual under the SERP or (v) apply for purposes of any plan, program or arrangement (A) under which similarly situated employees of HCC and HBC do not receive credit for prior service or (B) that is grandfathered or frozen, either with respect to level of benefits or participation.

(c) If any Continuing Employee becomes eligible to participate in any HCC Benefit Plan that provides medical, hospitalization or dental benefits, HCC or HBC, as applicable, shall request from the appropriate sponsor or provider that (i) any pre-existing condition limitations or eligibility waiting periods under such HCC Benefit Plan be waived with respect to such Continuing Employee and his or her covered dependents to the extent such limitation would have been waived or satisfied under a UAB employee benefit plan in which such Continuing Employee participated immediately prior to the Effective Time, and (ii) recognize any health expenses incurred by such Continuing Employee and his or her covered dependents in the year that includes the Closing Date (or, if later, the year in which such Continuing Employee is first eligible to participate) for purposes of any applicable deductible and annual out-of-pocket expense requirements under any such HCC Benefit Plan.

(d) HCC in its sole discretion, may elect to terminate the UAB 401(k) Plan or to discontinue contributions to the UAB 401(k) Plan anytime following the Effective Time, to cause UAB to terminate the 401(k) Plan to be effective at the Effective Time, or to merge the UAB 401(k) Plan with and into the HBC 401(k) Plan after the Effective Time. In no event shall the UAB 401(k) Plan be merged with and into the HBC 401(k) Plan, unless HCC determines in its reasonable judgment that (i) the UAB 401(k) Plan is a qualified plan under Section 401(a) of the Code, both as to the form of the UAB 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 UAB 401(k) Plan. If HCC determines in its sole discretion not to merge the UAB 401(k) Plan into the HBC 401(k) Plan and that the UAB 401(k) Plan should be terminated prior to the Effective Time, UAB agrees to take all action necessary to have the UAB 401(k) Plan terminated prior to the Effective Time.

(e) As of the Effective Time, HCC and HBC will assume the UAB Change in Control Severance Plan dated August 22, 2017 and the UAB Executive Change in Control Severance Plan dated August 22, 2017.

(f) Without limiting the generality of Section 9.09, the provisions of this Section 6.11 are solely for the benefit of the parties to this Agreement, and no current or former employee or any other individual associated therewith shall be regarded for any purpose as a third-party beneficiary of this Agreement. In no event shall the terms of this Agreement be deemed to (i) establish, amend or modify any UAB Benefit Plan or any “employee benefit plan” as defined in Section 3(3) of ERISA, or any other benefit plan, program, agreement or arrangement maintained or sponsored by HCC, HBC, or UAB, (ii) alter or limit the ability of HCC or HBC to amend, modify or terminate any UAB Benefit Plan or HCC Benefit Plan, employment agreement or any other benefit or employment plan, program, agreement or arrangement after the Closing Date, or (iii) confer upon any current or former employee, officer, director or consultant any right to employment or continued employment or continued service with HCC or HBC, or constitute or create an employment agreement with any employee.

(g) UAB will not send any written notices or other written communication materials to its employees without the prior written consent of HCC with respect to matters described in this Section 6.11.

Section 6.12 Directors’ and Officers’ Indemnification and Insurance.

(a) From and after the Effective Time, HCC shall indemnify and hold harmless each person who is now, or who has been at any time before the date of this Agreement, or who becomes before the Effective Time, an officer or director of UAB (each an “UAB Indemnified Party” and collectively, “UAB Indemnified Parties”) against all losses, claims, damages, costs, expenses (including attorneys’ fees), liabilities or judgments or amounts that are paid in settlement (which settlement shall require the prior written consent of HCC) of or in connection with any claim, action, suit, proceeding, investigation or other legal proceeding, whether civil, criminal, administrative or investigative or investigation (each, a “Claim”), in which an UAB Indemnified Party is, or is threatened to be made, a party or witness, arising out of, in whole or in part, the fact that such person is or was a director or officer of UAB if such Claim pertains to any matter of fact arising, existing or occurring at or before the Effective Time (including the Merger and the other Contemplated Transactions), regardless of whether such Claim is asserted or claimed before or after the Effective Time, to the fullest extent permitted under UAB’s Charter Documents and applicable Law. HCC shall advance and pay reasonable expenses (including reasonable attorneys’ fees) to the extent permissible under applicable Law upon receipt of an undertaking to repay such payments if he or she shall be adjudicated or determined to be not entitled to indemnification under this Section 6.12.

(b) Any UAB Indemnified Party wishing to claim indemnification under Section 6.12(a), upon learning of any Claim, shall promptly notify HCC thereof; provided, however, that failure to so notify will not affect the obligations of HCC under Section 6.12(a) unless and to the extent that HCC is actually prejudiced as a consequence. In the event of any such Legal Action (whether arising before or after the Effective Time), (i) HCC shall have the right to assume the defense thereof and HCC shall not be liable to such UAB Indemnified Parties for any legal expenses of other counsel or any other expenses subsequently incurred by such Indemnified Parties in connection with the defense thereof, except that if HCC elects not to assume such defense or if counsel for any of the UAB Indemnified Parties advises HCC that there are issues which raise conflicts of interest between the Indemnifying Party and any of the UAB Indemnified Parties that make joint representation inappropriate, the UAB Indemnified Parties may retain counsel which is reasonably satisfactory to the UAB Indemnified Parties, and HCC shall pay all reasonable fees and expenses of such counsel for UAB Indemnified Parties promptly as statements therefor are received; provided, however, that HCC shall be obligated pursuant to this Section 6.12(b) to pay for only one firm of counsel for all of the UAB Indemnified Parties in any jurisdiction, (ii) the UAB Indemnified Parties will cooperate in the defense of any such Claim, and (iii) HCC shall not be liable for any settlement effected without its prior written consent; and provided, further, that HCC shall not have any obligation hereunder to any UAB Indemnified Party when and if a court of competent jurisdiction shall determine, and such determination shall have become final, that the indemnification of such Indemnified Party in the manner contemplated under Section 6.12(a) is prohibited by applicable Law.

(c) Prior to the Effective Time, HCC and UAB shall cause the persons serving as officers and directors of UAB immediately prior to the Effective Time to be covered by a directors’ and officers’ liability insurance tail policy obtained from UAB’s current insurance carrier (the “Tail Insurance Policy”) of substantially the same coverage and amounts containing terms and conditions which are generally not less advantageous than UAB’s current policy with respect to acts or omissions occurring prior to the Effective Time that were committed by such officers and directors in their capacity as such for a period of six (6) years; provided, however, that in no event shall the cost of the Tail Insurance Policy be more than two hundred seventy-five percent (275%) of the current amount expended on an annual basis by UAB for its current policy; provided, further, that if the Tail Insurance Policy cannot be obtained as provided by this Section 6.12(c), HCC shall use its commercially reasonable efforts to obtain as much comparable insurance as is available for a premium amount up to such limit; provided, further, that officers and directors of UAB may be required to make application and provide customary representations and warranties to an insurance carrier for the purpose of obtaining the Tail Insurance Policy.

(d) This Section 6.12 shall survive the Effective Time and is intended to benefit each Indemnified Person and his or her heirs and representatives (each of whom shall be entitled to enforce this Section 6.12 against HCC) and shall be binding on all successors and assigns of HCC.

Section 6.13 Human Resources Issues.

(a) Communication with Employees. Prior to making any initial written or oral communications to the employees of UAB concerning the Merger, UAB will consult in good faith with HCC regarding the nature and content of any formal presentation of the Merger to employees of UAB and will, if requested by HCC, include a HCC representative in any group

presentation or any formal group meeting at which the transaction is explained or discussed, under an arrangement that is mutually satisfactory to the parties. UAB and HCC agree to work in good faith with each other to facilitate the timely and accurate dissemination of information to employees of UAB regarding matters related to the Merger in such a manner as to cause minimal disruption of the business of UAB and its relationships with its employees and to facilitate the transition of such relationships to HCC and HBC. In addition, UAB shall advise HCC of any material informal communications to UAB, its officers or employees, pertaining to compensation or benefit matters that are affected by the Contemplated Transactions; provided, however, that such communications must be consistent with pre-agreed to talking points prepared by UAB and HCC. UAB shall provide HCC with a copy of any intended communication, and will consult respecting the contents of any oral communications, in order to maintain a message consistent with the pre-agreed to talking points. HCC and UAB shall cooperate in providing any such mutually agreeable communication.

(b) Training. HCC and HBC shall have the right, but not the obligation, within thirty (30) business days prior to the Closing Date, to provide training to employees of UAB who will become employees of HCC or HBC. Such training shall be at the expense of HCC and HBC and shall be conducted during normal business hours. At the request of UAB, HCC shall compensate employees, in accordance with UAB’s customary policies and practices, for the employee’s time being trained by HCC and HBC. UAB shall cooperate with HCC to make such employees available for such training prior to Closing.

(c) Nothing in this Section 6.13 is intended, nor shall it be construed, to confer any rights or benefits upon any persons other than HCC, HBC or UAB.

Section 6.14 Transition.

(a) Commencing following the date of this Agreement, and in all cases subject to applicable Law, ATB and UAB shall cooperate with HCC and HBC to facilitate the integration of the parties and their respective businesses. Without limiting the generality of the foregoing, during the Pre-Closing Period and consistent with the performance of their day-to-day operations and the continuous operation of UAB in the ordinary course of business, UAB shall cause the employees and officers of UAB to cooperate with HCC and HBC in performing tasks reasonably required in connection with such integration, including requesting reasonable support from its outside contractors and vendors. ATB and UAB shall cooperate with HCC and HBC in minimizing the extent to which any contracts will continue in effect following the Effective Time.

(b) Without limiting the generality of Section 6.14(a), ATB and UAB shall use all reasonable efforts to provide data processing, item processing and other processing support or outside contractors to assist HCC and HBC performing all tasks reasonably required to result in a successful conversion of the data and other files and records of UAB to the production environment of HCC and HBC, when requested by HCC and in such a manner sufficient to ensure that a successful conversion will occur at the time (on or after the Effective Time) designated by HCC; provided, however, that if requested by HCC, ATB and UAB shall take all steps reasonably necessary to allow HCC and HBC to convert to UAB’s existing production environment. Among other things, ATB and UAB shall (i) cooperate with HCC and HBC to

establish a mutually agreeable project plan to effectuate the conversion, (ii) use its commercially reasonable efforts to have UAB’s outside contractors continue to support both the conversion effort and its on-going needs until the conversion can be established, (iii) provide, or use its commercially reasonable efforts to obtain from any outside contractors, all data or other files and layouts requested by HCC or HBC for use in planning the conversion, as soon as reasonably practicable, (iv) provide reasonable access to the personnel and facilities of UAB and, with the consent of its outside contractors, its outside contractors’ personnel and facilities, to enable the conversion effort to be completed on schedule, and (v) give notice of termination, conditioned upon the completion of the Merger and the transactions contemplated by this Section 6.14, of the Contracts of outside data, item and other processing contractors or other third-party vendors when directed to do so by HCC. HCC agrees that (x) all actions taken pursuant to this Section 6.14 shall be taken in a manner intended to minimize disruption to the customary business activities of UAB and (y) UAB shall not be obligated to take any action pursuant to this Section 6.14 that would obligate UAB or ATB to pay, or become committed to pay any amounts prior to the Effective Time unless conditioned upon the completion of the Merger.

Section 6.15 Pre-Closing Policies and Actions. At or before the Closing Date, provided, however, that all of the conditions in Article VI are satisfied or waived (other than those conditions that, by their nature, would be satisfied at or as of the Closing):

(a) UAB shall, consistent with GAAP and applicable banking laws and regulations, to the extent requested by HCC, modify or change its loan, OREO, accrual, reserve, tax, litigation and real estate valuation policies and practices (including loan classifications and levels of reserves) so as to be applied on a basis that is consistent with that of HCC and HBC.

(b) UAB shall (i) make such accounting entries or adjustments as HCC shall direct as a result of its on-going review of UAB that are consistent with GAAP in order to implement its plans following the Closing or to reflect expenses and costs related to the Merger, and (ii) shall, consistent with GAAP, the rules and regulations of the SEC and the rules and regulations of any bank regulatory agency and applicable Law, modify or change its loan, OREO, accrual, reserve, Tax, litigation and real estate valuation policies and practices (including loan classifications and levels of reserves) so as to be applied on a basis that is consistent with that of HCC.

(c) Unless the recording adjustments pursuant to Section 6.15(a) or (b) or modification or changes pursuant to this Section 6.15 would otherwise be necessary to be consistent with applicable Law or with regulatory accounting principles or GAAP, no such adjustment or modification or change shall constitute or be deemed to be a breach, violation of or failure to satisfy any representation, warranty, covenant, agreement, condition or other provision of this Agreement or otherwise be considered in determining whether any such breach, violation or failure to satisfy shall have occurred, or as an admission or acknowledgement by UAB that any such adjustment or modification or change is appropriate or required or that any financial statement or information previously provided by UAB was incorrect in any respect.

(d) UAB shall fully correct, remedy and otherwise resolve any fact or circumstance to the knowledge of UAB, that has resulted, or could reasonably be expected to result, in any Loan that (i) is not evidenced by Loan Documentation that is correct and complete, (ii) does not represent the valid and legally binding obligation of the Obligor thereunder, or (iii) is not

enforceable against the Obligor in accordance with its terms (except as may be limited by applicable bankruptcy, insolvency, moratorium, or other similar Law affecting the enforcement of creditors’ rights generally, and subject to general principles of equity (whether considered in a proceeding whether in equity or at law)), such that the applicable Loan or Loan Documentation fully complies with Section 3.14.

Section 6.16 Expense Report; Transaction Expenses. UAB shall have caused its attorneys, accountants, auditors and investment bankers which rendered services to UAB in connection with the Contemplated Transactions (collectively, the “Advisors”) to have submitted to UAB estimates of their fees and expenses for all services rendered in any respect in connection with the Contemplated Transactions and their reasonable estimates of the amounts of the fees and expenses they expect to incur up to and including the Closing Date at least five (5) business days prior to the Closing Date. UAB shall have prepared and submitted to HCC no later than five (5) business days prior to the Closing Date a final calculation of all Transaction Expenses, certified by UAB’s Principal Accounting Officer with support for all items therein in a form and substance reasonably acceptable to HCC. Based on such summary, UAB shall have prepared and submitted a final calculation of such fees and expenses, and UAB, shall have accrued and paid the amount of such fees and expenses as calculated above. UAB shall have caused the Advisors to submit their final bills for such fees and expenses to UAB for services rendered prior to the Closing Date and such Advisors shall have released UAB, HCC and the Surviving Corporation from liability, or shall have advised them in writing that, upon payment in full of such amounts, they shall have no liability for any fees or expenses to such Advisors.

Section 6.17 Closing Financial Statements. At least five (5) business days prior to the Closing Date, UAB shall deliver the unaudited balance sheet of UAB in form and substance satisfactory to HCC, as of the close of business on the last business day of the calendar month ended immediately preceding the Closing Date or, if the Closing Date occurs during the first five business days of the month, as of the close of business on the last business day of the second month immediately preceding the Closing Date (the “Closing Balance Sheet Date”) and UAB’s unaudited statement of income for the period January 1, 2017 through the close of business on the Closing Balance Sheet Date (together with the Closing Balance Sheet, the “Closing Financial Statements”). The Closing Financial Statements shall (a) fairly present in all material respects the assets, liabilities and tangible common equity of UAB as of the date of the Closing Financial Statements, (b) be prepared in a manner consistent with the balance sheets included in UAB Financial Statements, in accordance with either GAAP or regulatory accepted accounting procedures, as applicable, consistently applied, and (c) be prepared from, and be in accordance with, the books and records of UAB provided, however, that for purposes of the Closing Financial Statements any OREO shall be written down to zero. The Closing Financial Statements shall be accompanied by a certificate of UAB’s Principal Accounting Officer, dated as of the Effective Time, to the effect that such financial statements continue to reflect accurately, as of the date of the certificate, the financial condition of UAB in all material respects.

Section 6.18 Shareholder Litigation. ATB and UAB shall promptly advise HCC orally and in writing of any shareholder litigation against ATB or UAB or its respective directors relating to this Agreement, the Merger or the other Contemplated Transactions to which ATB or UAB has knowledge and shall keep HCC fully informed regarding any such shareholder litigation, including providing all relevant documentation. ATB and UAB shall consult with HCC and give good faith consideration of its comments and advice and give HCC the opportunity to participate in the defense or settlement of any such litigation at HCC’s expense. No settlement shall be agreed to without HCC’s prior written consent.

Section 6.19 ATB Auditor Cooperation. ATB shall cooperate, and use its commercially reasonable efforts to cause ATB’s independent auditor to cooperate, at ATB’s expense, with HCC and its independent auditor in order to enable HCC and HBC to prepare financial statements, including, without limitation, pro forma financial information, for UAB that may be required by HCC or HBC in connection with the filing of regulatory applications with Governmental Entities or otherwise required in connection with the Contemplated Transactions. Without limiting the generality of the foregoing, ATB and UAB agree that they will (a) consent to the use or incorporation of such audited and/or reviewed financial statements in any registration statement, periodic report or other document that it is required to be delivered to shareholders of HCC or filed by HCC or HBC and (b) execute and deliver, and cause its officers to execute and deliver (including former officers of ATB after the Closing), such “representation” letters as are customarily delivered in connection with audits and as the independent auditors or UAB or HCC may respectively reasonably request under the circumstances.

Section 6.20 Third Party Consents; Estoppel. UAB shall use its reasonable best efforts to obtain and deliver to HCC prior to the Effective Time:

(a) The consents, approvals or waivers required to be obtained from any third-parties in connection with the Merger and the other Contemplated Transactions (in such form and content as is approved in writing by HCC) promptly after the date of this Agreement, including, without limitation, the waiver, approval or consents to assignment for all the Real Estate Leases and any UAB Material Contracts. UAB shall cooperate with HCC in minimizing the extent to which any Contracts will continue in effect following the Effective Time, in addition to complying with Section 6.01(a)(iii) and (b)(xxi);

(b) Lessor estoppel certificates in the form reasonably satisfactory to HCC relative to the Leased Real Estate dated not earlier than twenty (20) days prior to the Closing Date;

(a) Prior to the Effective Time, UAB shall use its reasonable best efforts to obtain consents to the partial or complete assignments of any of its respective insurance policies if requested to do so by HCC, to the extent necessary to maintain the benefits to HCC and the Surviving Corporation of such policies as they apply to UAB. UAB shall also inform HCC no later than five (5) business days prior to the Closing Date of any material unfiled insurance claims to the knowledge of UAB, and for which it believes coverage exists.

(b) Prior to the Effective Time, UAB and HCC shall cooperate to determine the most appropriate methodology to obtain “tail” insurance coverage at such limits, mutually agreeable to the parties, for Errors and Omissions, Bankers and Blanket Bond coverage and any other insurance policies of UAB as mutually agreed.

Section 6.22 Takeover Provisions. No party shall take any action that would cause the Contemplated Transactions to be subject to requirements imposed by any Takeover Provisions, and each party shall, if any Takeover Provision becomes applicable to this Agreement and the Contemplated Transactions, take all necessary steps within its control to exempt (or ensure the continued exemption of) those transactions from or if necessary challenge the validity or applicability of any applicable Takeover Provision as now or hereafter in effect.

UAB shall have the right to review and approve the substance any such communications, provided however, that UAB shall not unreasonably withhold, delay or condition its approval. HBC shall consult with UAB, and UAB upon request shall assist HBC, with respect to sending necessary or appropriate customer notifications and communications as prepared by HBC, to advise such customers of the impending transaction and of HBC’s plans following the Effective Time.

Section 6.24 Tax Matters.

(a) HCC, ATB and UAB shall not take any action prior to Effective Time that could reasonably be expected to potentially cause the Merger not to qualify as a reorganization under Section 368(a) of the Code. HCC, ATB and UAB shall use their respective reasonable commercial efforts to cause counsel to HCC and counsel to UAB to render opinions that the Merger qualifies as a reorganization with the meaning of Section 368(e) of the Code, provided, however, that such counsel shall have received representation letters executed and delivered by the appropriate executive officers of UAB, ATB and HCC acceptable to such counsel described in Section 7.02(e).

(b) UAB shall cause the provisions of any Tax Sharing Agreement to which UAB is a party to be terminated prior to the Effective Time.

(c) From and after the Closing Date, except as set forth in the next sentence, ATB shall control the conduct, through counsel of its own choosing, of any audit, claim for refund, or administrative or judicial proceeding involving any asserted Tax liability or refund with respect to UAB (each, a “contest”). In the case of a contest after the Closing Date that involves a liability or disputed Tax of UAB, ATB shall control the conduct of such contest, but HCC shall have the right to participate in such contest at its own expense. ATB shall promptly deliver to HCC copies of all relevant notices and documents (including court papers) received by ATB in connection with any such contests, and shall not enter into a settlement, compromise or concede any portion of any contest that could affect a UAB Tax liability without the prior written consent of HCC, which consent shall not be unreasonably be denied or timely delivered.

Section 6.27 Public Announcement. The initial press release with respect to this Agreement and the Contemplated Transactions shall be a release mutually agreed to by UAB and HCC. Thereafter, each of UAB, HCC and HBC agree that no public release or announcement concerning the Contemplated Transactions shall be issued by any party without the prior written consent of the other party, except as required by applicable Law or the rules or regulations of any applicable United States securities exchange or Governmental Entity to which the relevant party is subject, in which case the party required to make the release or announcement shall consult with the other party about, and allow the other party reasonable time to comment on such release or announcement in advance of such issuance.

Section 6.28 Further Assurances. Each party covenants that it will use its reasonable efforts to consummate the Contemplated Transactions as soon as practicable.

All information disclosed by one party to any other party to this Agreement, whether prior or subsequent to the date of this Agreement including, without limitation, any information obtained pursuant to this Agreement or the negotiations relating to this Agreement, shall be kept confidential by such other party and shall not be used by such other party otherwise as herein contemplated. In the event that this Agreement is terminated, each party shall return all documents furnished hereunder, shall destroy all documents or portions thereof prepared by such other party that contain information furnished by another party pursuant hereto and, in any event, shall hold all information confidential unless or until such information is or becomes a matter of public knowledge other than as a result of a violation of the Confidentiality Agreement.

ATB shall have executed and delivered to HCC a Shareholder Agreement in the form of Annex D and a non-solicitation and confidentiality agreement in the form of Annex E, and such agreements shall be in force and effect and no breach of any of their respective terms shall have occurred. Each UAB employee receiving a severance or Change In Control Payment shall execute and deliver to HCC a release agreement in the form reasonably satisfactory to HCC and such agreement shall be in full force effect and no breach of their respective terms shall have occurred.

(l) UAB/ATB Agreements. UAB and ATB, as applicable, shall have executed and delivered to HBC the agreements substantially in the forms set forth on the Closing Schedule; such agreements shall be in full force and effect and no breach of any of its respective terms shall have occurred.

HBC shall have confirmed that with respect to UAB’s leased premises for its Half Moon Bay and San Mateo branch offices, UAB is not required to subordinate its leasehold interest to the lien of any mortgage or deed of trust encumbering the property on which the leases premises are located unless the landlord provides UAB with a commercially reasonable non-disturbance agreement (except where the failure to deliver any such nondisturbance agreements would not likely have a HCC Material Adverse Effect following the Merger).

(o) Regulatory Actions. Neither HCC nor HBC shall be, as a result of the Merger (as a successor or otherwise), subject to any memorandum of understanding, cease and desist order regulatory resolution or other agreement with any Governmental Entity (“Regulatory Actions”). In the event that UAB is subject to any Regulatory Action that is not terminated before or in connection with the Merger, the condition contemplated by this provision shall be deemed to have not been satisfied.

(p) Estoppel Letters and Consents. UAB and ATB shall have delivered to HCC fully executed consents and estoppel letters as provided in Section 6.20 (except where the failure to deliver any such estoppel letters would not likely have a HCC Material Adverse Effect following the Merger).

(r) Termination of Contracts. The ATB Contracts listed on Section 7.02(r) of the UAB Disclosure Schedule shall be terminated without expense or surviving obligations to HCC on or prior the Closing Date.

(s) Closing Proceedings and Documents. All corporate and other proceedings in connection with the transactions contemplated at the Closing and all documents incident thereto shall be reasonably satisfactory in form and substance to HCC and to HCC’s counsel, and they shall each have received all such counterpart originals and certified or other copies of such documents as they may reasonably request. Such documents shall include (but not be limited to) a copy of the resolutions of the UAB Board and the shareholders of UAB evidencing the requisite approval of this Agreement, the Merger, and the other Contemplated Transactions and certified by the Secretary of UAB as true and correct copies thereof as of the Closing, which resolutions shall be in full effect.

Section 7.03 Conditions to Obligation of ATB and UAB. The obligation of UAB to effect the Merger is also subject to the satisfaction or waiver by ATB and UAB on or prior to the Closing Date of the following conditions:

(a) Representations and Warranties. The representations and warranties of HCC and HBC set forth in this Agreement shall be true and correct as of the date of this Agreement and as of the Closing Date as though made on and as of the Closing Date (unless any such representation and warranty by its terms speak specifically as of a date of this Agreement or another date then true and correct as of such date) provided, however, that no representation or warranty of HCC or HBC (other than the representations and warranties set forth in (i) Sections 5.05 and 5.06 which shall be true and correct in all material respects, and (ii) Section 5.01(a), (b), 5.02, 5.03(a) and (b)(i) and (ii)(A), and 5.11, which shall be true and correct in all respects) shall be deemed untrue or incorrect for purposes hereunder as a consequence of the existence of any fact, event or circumstance inconsistent with such representation or warranty, unless such fact, event or circumstance, individually or taken together with all other facts, events or circumstances inconsistent with any representation or warranty of HCC or HBC has had or would reasonably be expected to result in a HCC Material Adverse Effect; provided further, that for purposes of determining whether a representation or warranty is true and correct for purposes of this Section 7.03(a) any qualification or exception for, or reference to, materiality (including the terms “material,” “materially,” “in all material respects,” “Material Adverse Effect” or similar terms or phrases) in any such representation or warranty shall be disregarded.

(b) Performance of Obligations of HCC and HBC. HCC and HBC shall have performed in all material respects all obligations required to be performed by it under this Agreement at or prior to the Effective Time.

(c) HCC Material Adverse Effect. Since the date of this Agreement, no event shall have occurred or circumstance arisen that, individually or taken together with all other facts, circumstances or events, has had or would reasonably be expected to have an HCC Material Adverse Effect.

(d) Officer’s Certificate. UAB shall have received a certificate signed on behalf of HCC by its Chief Executive Officer and Chief Financial Officer stating that the conditions specified in Section 7.03(a), Section 7.03(b) and Section 7.03(c) have been satisfied.

(e) Opinion of Tax Counsel. UAB shall have received an opinion from Sheppard, Mullin, Richter & Hampton, LLP, legal counsel to UAB, dated the Closing Date, to the effect that, on the basis of the facts, representations and assumptions set forth or referred to in such opinion, the Merger will qualify as a “reorganization” within the meaning of Section 368(a) of the Code. In rendering its opinion Sheppard, Mullin, Richter & Hampton, LLP may require and reply upon representations contained in letters from each of HCC, ATB and UAB. Each of HCC and UAB shall have delivered to such counsel a certificate acceptable to Sheppard, Mullin, Richter & Hampton, LLP, dated as of the Closing Date, signed on behalf of each of HCC, ATB and UAB by an appropriate executive officer.

(f) Closing Proceedings and Documents. All corporate and other proceedings in connection with the transactions contemplated at the Closing and all documents incident thereto shall be reasonably satisfactory in form and substance to UAB and to UAB’s counsel, and they shall each have received all such counterpart originals and certified or other copies of such documents as they may reasonably request. Such documents shall include (but not be limited to) the following a copy of the resolutions of the Boards of Directors of HCC and HBC evidencing the requisite approval of this Agreement, the Merger, and the other Contemplated Transactions, certified by the Secretary of HCC as true and correct copies thereof as of the Closing.

(d) by either HCC or UAB if the UAB Meeting (including any postponements or adjournments thereof) shall have been held and the Requisite UAB Vote shall have not been obtained; provided, however, that the party seeking to terminate this Agreement under this Section 8.01(d) shall have complied with its obligations under Section 6.06 (including by complying with an adjournment or postponement request under Section 6.06(c)); provided further, however, that the right to terminate this Agreement under this Section 8.01(d) will not be available to a party where the failure to obtain the approval of its shareholders has been caused by (i) its breach of this Agreement, or (ii) in the case of UAB a breach of one or more of the Shareholder Agreements or the ATB Shareholder Agreement;

(e) by HCC if (i) the UAB Board effects a Change in Recommendation or (ii) ATB, UAB, or any of their Representatives, shall have violated, breached, or taken any action inconsistent with any of the provisions set forth in Section 6.04 or Section 6.06;

(g) by UAB (if UAB is not otherwise in material breach of this Agreement) (i) if (A) HCC or HBC breaches any of its representations and warranties made on the date of this Agreement, or any such representations and warranties shall become untrue after the date of this Agreement, in each case such that the condition set forth in Section 7.03(a) would not be satisfied, and (B) such inaccuracy, if capable of cure by its nature or timing, has not been cured by HCC or HBC, as the case may be, within thirty (30) days after its receipt of written notice of such breach, or (ii) if HCC or HBC breaches any of its covenants contained in this Agreement such that the condition set forth in Section 7.03(b) would not be satisfied and such breach if curable by its nature or timing shall not have been cured within thirty (30) days following HCC’s receipt of written notice from UAB of such breach; or

Section 8.03 Expenses; Termination Fees.

(a) Except as set forth in this Section 8.03, all fees and expenses incurred in connection with this Agreement and the Contemplated Transactions shall be paid by the party incurring such expenses, whether or not the Merger is consummated.

Section 9.03 No Survival. The representations, warranties and covenants in this Agreement shall terminate at the Effective Time, provided, however, that those covenants and agreements contained herein that by their terms apply, or that are to be performed in whole or part, after the Effective Time, shall survive the consummation of the Merger until fully performed.

Section 9.04 Entire Agreement. This Agreement, together with the Confidentiality Agreements, the UAB Disclosure Statement, and Annexes constitute the entire agreement among the parties and supersede all other prior or contemporaneous agreements and understandings, both written and oral, among or between any of the parties with respect to the subject matter this Agreement and thereof.

(a) The Agreement may be executed in several counterparts, each of which shall be deemed an original and all of which shall constitute one and the same instrument and shall become effective when counterparts have been signed by each of the parties and delivered to the other parties; it being understood that all parties need not sign the same counterpart.

(b) The exchange of signed copies of this Agreement or of any other document contemplated by this Agreement (including any amendment or any other change thereto) by any electronic means intended to preserve the original graphic and pictorial appearance of a document shall constitute effective execution and delivery of this Agreement as to the parties and may be used in lieu of an original Agreement or other document for all purposes. Signatures of the parties transmitted by any electronic means referenced in the preceding sentence shall be deemed to be original signatures for all purposes.

Section 9.06 Governing Law.

Section 9.08 Assignments and Successors. No party may assign any of its rights or delegate any of its obligations under this Agreement without the prior written consent of the other parties.

This Agreement will be binding upon, and shall be enforceable by and inure solely to the benefit of, the parties and their respective successors and permitted assigns.

Section 9.09 No Third-Party Rights. Nothing in this Agreement, express or implied, is intended to or shall confer upon any person (other than the parties) any right, benefit, or remedy of any nature whatsoever under or by reason of this Agreement other than the provisions of Section 6.12(a) (which are intended to be for the benefit of those persons covered thereby, but whose consent shall not be required to amend any provision of this Agreement).

Section 9.14 Definitions. For purposes of this Agreement, the following terms will have the following meanings:

“Acceptable Confidentiality Agreement” means an agreement that is either (a) in effect as of the execution and delivery of this Agreement, or (b) executed, delivered and effective after the execution of this Agreement, in either case containing provisions that require any counterparty(ies) thereto (and any of its (their) Representatives named therein) that receive material non-public information of or with respect to UAB to keep such information confidential; provided, however, that in the case of clause (b) that such agreement shall (i) not prohibit UAB from providing information to HCC or require UAB to negotiate on an exclusive basis with such counterparty(ies) thereto (and any of its (their) Representatives named therein) and (ii) contains such terms and conditions that are at least as protective of UAB’s confidential information as those contained in the Confidentiality Agreement.

“Acquisition Proposal” means any proposal, offer, indication of interest or inquiry from any person or group for, whether in one transaction or a series of related transactions, or relating to any (a) merger, consolidation, share exchange or business combination involving more than 10% of the total voting power of any class of the capital stock of UAB, (b) sale, lease, exchange, mortgage, transfer or other disposition, directly or indirectly, by merger, consolidation, combination, reorganization, share exchange or any similar transaction, of any assets of UAB representing 10% or more of the consolidated assets of UAB, measured either by book value or fair market value, (c) issuance, sale or other disposition by UAB of (including by way of merger, consolidation, share exchange or any similar transaction) securities (or options, rights or warrants to purchase, or securities convertible into, such securities) representing 10% or more of the votes associated with the outstanding voting of any class of equity securities of UAB, (d) tender offer or exchange offer in which any person or “group” (as such term is defined under the Exchange Act) shall acquire beneficial ownership (as such term is defined in Rule 13d-3 under the Exchange Act), or the right to acquire beneficial ownership, of 10% or more of the outstanding UAB Common Stock or any class of equity securities of UAB, (e) recapitalization, liquidation, dissolution or other similar type of transaction with respect to UAB which would result in any person or group acquiring 10% or more of the fair market value of the assets of UAB taken as a whole, or (f) transaction which is similar in form, substance or purpose to any of the foregoing transactions; provided, however, that the term “Acquisition Proposal” shall not include the Merger, any of the other Contemplated Transactions or any transaction that constitutes a ATB Change of Control Transaction.

For the purposes of this definition, “control” (including, the terms “controlling,” “controlled by” and “under common control with”), as applied to any person, means the possession directly or indirectly of the power to direct or cause the direction of the management and policies of that person, whether through the ownership of voting securities by Contract or otherwise. Neither UAB nor any of its Affiliates shall be deemed an Affiliate of HCC, HBC or any of their respective Subsidiaries for purposes of this Agreement prior to the Effective Time and neither HCC, HBC nor any of their respective Affiliates shall be deemed an Affiliate of UAB for purposes of this Agreement prior to the Effective Time.

Shareholder will comply with the provisions of Section 5.04(c) of the Merger Agreement as if he, she or it were UAB.

6. Shareholder Capacity. Shareholder is entering this Agreement in his, her or its capacity as the record or beneficial owner of Shareholder’s Shares, and not in his, her or its capacity as a director of UAB or as a trustee of any UAB benefit plan, as applicable. Nothing in this Agreement shall be deemed in any manner to limit the discretion of Shareholder to take any action, or fail to take any action, in his, her or its capacity as a director of UAB, as a trustee of any UAB benefit plan or other capacity, as applicable, that may be required of Shareholder in the exercise of his, her or its fiduciary duties and responsibilities whether as a director of UAB, as a trustee of any UAB benefit plan or otherwise owed to any third party.

8. Term of Agreement; Termination. The term of this Agreement shall commence on the date hereof and terminate at the Effective Time.

A-3

9. Specific Performance. Shareholder acknowledges that it is a condition to the willingness of HCC to enter into the Merger Agreement that Shareholder execute and deliver this Agreement and that it will be impossible to measure in money the damage to HCC if Shareholder fails to comply with the obligations imposed by this Agreement and that, in the event of any such failure, HCC will not have an adequate remedy at law or in equity. Accordingly, Shareholder agrees that injunctive relief or other equitable remedy is the appropriate remedy for any such failure and will not oppose the granting of such relief by a court of competent jurisdiction on the basis that HCC has an adequate remedy at law. Shareholder further agrees that Shareholder will not seek, and agrees to waive any requirement for, the securing or posting of a bond in connection with UAB’s seeking or obtaining such equitable relief. Such injunctive and other equitable remedies are cumulative and shall be HCC’s sole remedy under this Agreement, unless HCC shall have sought and been denied by a court of competent jurisdiction injunctive or other equitable remedies and such denial is other than by reason of violation of this Agreement by HCC.

10. Confidentiality. Shareholder agrees (a) to hold any and all information regarding this Agreement, the Merger and the Merger Agreement in strict confidence, and (b) not to divulge any information regarding this Agreement, the Merger or the Merger Agreement to any third party (other than Representative’s legal counsel or tax advisors who owe Representative a legal duty of confidentiality with respect to such information), until such time as the Merger has been publicly announced by HCC and UAB, at which time Shareholder may only divulge such information as has been publicly disclosed by HCC and UAB.

If any provision of this Agreement shall, for any reason, be held by a court of competent jurisdiction to be invalid, illegal or unenforceable, such invalidity, illegality or unenforceability shall not affect any other provision of this Agreement, but this Agreement shall be construed as if such invalid, illegal or unenforceable provision had never been contained herein.

ANNEX B

FORM OF NON-SOLICITATION, NON-COMPETITION AND
CONFIDENTIALITY AGREEMENT

This NON-SOLICITATION, NON-COMPETITION AND CONFIDENTIALITY AGREEMENT (this “Agreement”), dated as of January 10, 2018, is made by and among Heritage Commerce Corp, a California corporation (“HCC”), Heritage Bank of Commerce, a California state-chartered bank and wholly-owned subsidiary of HCC (“HBC”), and the undersigned director (“Representative”) of United American Bank, a California banking corporation (“UAB”). The Agreement shall become effective at the Effective Time as defined in the Merger Agreement (described below).

Recitals

A. HCC, HBC and UAB are entering into an Agreement and Plan of Merger and Reorganization (and as it may be amended, the “Merger Agreement”), dated the date of this Agreement, pursuant to which UAB shall merge with and into HBC (the “Merger”) on the terms and conditions set forth therein and, in connection therewith, each share of UAB common stock (“UAB Common Stock”) and UAB preferred stock will be converted into the right to receive the consideration set forth in the Merger Agreement. Unless otherwise indicated, capitalized terms used and not defined herein shall have the meanings set forth in the Merger Agreement.

B. Representative owns shares of UAB Common Stock and, as a result, Representative has a material economic interest in the consummation of the Merger.(1)

C. Following the Merger, the business and operations of HCC, HBC and UAB could be irreparably injured if Representative were to undertake certain activities competitive with HCC, HBC or UAB.

D. In order to induce HCC and HBC to enter into the Merger Agreement and consummate the Merger, Representative has agreed to enter into and perform this Agreement.

NOW, THEREFORE, in consideration of the transactions contemplated by the Merger Agreement and the benefits to be derived, directly or indirectly, by Representative under the Merger Agreement, and in consideration of the mutual covenants contained herein, and for other good and valuable consideration, the receipt, sufficiency and adequacy of which are hereby acknowledged, the parties hereto, intending to be legally bound, agree as follows:

1. Acknowledgments by Representative; Support.

(a) Representative acknowledges that by virtue of his or her positions with UAB, he or she has developed considerable expertise in the business operations of UAB and has access to extensive confidential information with respect to UAB and has access to Confidential Information (as defined below). Representative recognizes that HCC and HBC would be irreparably damaged, and HCC’s and HBC’s substantial investment as a result of the acquisition of UAB in the Merger would be materially impaired, if Representative were to (i) disclose or make unauthorized use of any Confidential Information, (ii) take certain actions relative to employees of UAB, or (iii) solicit current or prospective clients, customers, suppliers, agents or certain other Persons. Accordingly, Representative expressly acknowledges that he or she is voluntarily entering into this Agreement and that the terms and conditions of this Agreement are fair and reasonable to Representative in all respects.

(1) This recital to be omitted from agreements signed by directors who own no shares of UAB Common Stock.

B-1

(b) Representative agrees during the Applicable Period (as defined below) to support and refrain from (i) disparaging the goodwill of HCC, HBC and UAB, and (ii) harming the customer and client relationships of UAB as of the Effective Time of the Merger. For purposes of this Agreement, “Applicable Period” shall mean the period commencing on the Effective Time and ending on the later of: (i) two (2) years from and after the Effective Time, or (ii) one (1) year from and after the date on which Representative is no longer a director or employee of HCC or HBC.

2. Non Solicitation.

(a) In order that HCC and HBC may have and enjoy the full benefit of ownership of UAB and the business it conducts, including its goodwill, following the Effective Time of the Merger, Representative agrees that during the Applicable Period, (i) Representative will not take any affirmative action directly or indirectly attempt to hire, contact or solicit (other than general solicitations through newspapers or other media of general circulation not specifically targeted at such employees) with respect to hiring, any Person who was an employee of UAB at the Effective Time of the Merger and who becomes an employee of HCC, HBC or any of their respective Subsidiaries in connection with the Merger, or induce or otherwise counsel, advise or knowingly encourage any such Person to leave the employ of HCC, HBC or any of their respective Subsidiaries, and (ii) Representative will not directly or indirectly (A) induce, persuade, encourage or influence or attempt to induce, persuade, encourage or influence any Person who had a business relationship with UAB as of the Effective Time of the Merger and who continues to have a business relationship with HBC, HCC or any of its respective Subsidiaries on or after the Effective Time of the Merger, to discontinue, reduce or restrict such relationship or (B) solicit or target the deposits, loans or other products and services from or to Persons who were depositors, borrowers or customers of UAB as of the Effective Time of the Merger, whether by personal contact, by telephone, by facsimile, by mail or other form of solicitation or communication, or in any other way except for general solicitations that are directed to the general public and not directed specifically to Persons who were depositors, borrowers or customers of UAB as of the Effective Time of the Merger, [provided however, that the foregoing clause (ii) shall not prohibit Representative from soliciting the purchase of insurance or fixed annuities by any Person.](2)

(b) Representative acknowledges and agrees that the business conducted by UAB is highly competitive, a significant portion of UAB’s competitiveness and its value as a going enterprise is derived from its workforce and business relationships, and that the covenants made by Representative in this Section 2 are made in consideration of the Merger Consideration Representative will receive in exchange for Representative’s UAB Common Stock outstanding immediately prior to the Merger, and as a necessary inducement for HCC and HBC to enter into the Merger Agreement and consummate the transactions contemplated thereby. It is the desire and intent of the parties to this Agreement that the provisions of this Section 2 shall be enforced to the fullest extent permissible under the laws and public policies of each jurisdiction in which enforcement is sought. It is expressly understood and agreed that, although Representative, HCC and HBC each consider the restrictions contained in this Section 2 to be reasonable, if a final determination is made by a court of competent jurisdiction or an arbitrator that any restriction contained in this Section 2 is unenforceable against any party, the provisions of this Section 2 shall be deemed amended to apply to the maximum extent as such court may judicially determine or indicate to be enforceable. Representative acknowledges that breach of this Section 2 may cause HCC and HBC irreparable harm and that they may be entitled to the entry of an injunction without bond in the event Representative breaches or threatens to breach this Section 2.

(2) To be included in Mr. Bland’s agreement only.

B-2

3. Non-Competition. Without the prior written consent of HCC, which may be withheld in HCC’s sole and absolute discretion, during the Applicable Period, [with the exception of director positions with each of Tri-Valley Bank, First Banks, Inc., and Medley Management, Inc.,](3) Representative shall not, directly or indirectly, own, manage, operate, control, engage in or have any interest in any Person, firm, corporation or business (whether as an employee, officer, director, agent, security holder, or consultant, provided that Representative shall not be prohibited from making a passive investment not to exceed 5% of the outstanding shares of any class of security or of the total outstanding equity of any company) that engages, in any manner, in the provision of Commercial Banking Services (as defined below) in the Counties of Alameda, Contra Costa, Santa Clara or San Mateo, in the State of California. For purposes of this Agreement, “Commercial Banking Services” shall mean services that include both (i) the origination of secured or unsecured commercial, real estate, residential, construction and SBA loans, together with (ii) the solicitation and provision of deposits.(4)

4. Confidential Information; Trade Names and Styles.

(a) Without limiting the generality of Section 2 above, other than for the benefit of UAB, HCC, HBC or their respective Subsidiaries, Representative (i) shall make no use of Confidential Information , or any part thereof, and (ii) shall not disclose Confidential Information , or any part thereof, to any other Person, and (iii) shall, upon the request of HCC or HBC, deliver all documents, reports, drawings, designs, plans, proposals and other tangible evidence of Confidential Information now possessed or hereafter acquired by Representative to HCC and HBC. For purposes of this Agreement, “Confidential Information “ shall mean (a) all secrets and other confidential information, trade secrets, ideas, concepts, knowledge, know-how, techniques, secret processes, improvements, discoveries, methods, inventions, sales information, financial information, lists of customers and prospective customers, broker lists, potential brokers, rate sheets, market studies, marketing plans, business plans, concepts, strategies or products, as well as all documents, reports, drawings, designs, plans, and proposals otherwise pertaining to same, with respect to UAB, (b) any non-public personal information on any present or past customer or client of UAB, and (c) any other information, however documented, that is a trade secret within the meaning applicable trade secret protection Law. Notwithstanding the foregoing, “Confidential Information “ shall not include any (i) information which is or has become available from an independent third party who learned the information independently and is or was not bound by a confidentiality agreement with UAB, HCC or HBC with respect to such information, (ii) information which Representative independently develops or has developed without reference to such information, or (iii) information readily ascertainable from public, trade or other non-confidential sources (other than as a result, directly or indirectly, of disclosure or other dissemination in violation of an obligation or duty of confidentiality owed to UAB, HCC or HBC)

(b) Notwithstanding any provision of this Agreement to the contrary, Representative may disclose or reveal any information, whether including in whole or part any Confidential Information, that:

(i) Representative is required to disclose or reveal under applicable Law; provided, however, that Representative makes a good faith request that the confidentiality of the Confidential Information be preserved and, to the extent not prohibited by applicable Law and gives, HCC and HBC prompt advance notice of such requirement.

(3) To be included in Mr. Rounseville’s agreement only.

(4) Section 3 to be omitted from agreements signed by directors who own no shares of UAB Common Stock.

B-3

(ii) Representative is otherwise required to disclose or reveal by any Governmental Entity; provided, however, that Representative makes a good faith request that the confidentiality of the Confidential Information be preserved and, to the extent not prohibited by applicable Law, gives HCC and HBC prompt advance notice of such requirement.

(iii) In the written opinion of Representative’s legal counsel, Representative is compelled to disclose or else stand liable for contempt or suffer other censure or penalty imposed by any Governmental Entity; provided, however, that Representative makes a good faith request that the confidentiality of the Confidential Information be preserved and, to the extent not prohibited by applicable Law, gives HCC and HBC prompt advance notice of such requirement.

(c) Pursuant to 18 U.S.C. 1833(b), an individual shall not be held criminally or civilly liable under any federal or state trade secret law for the disclosure of a trade secret that (i) is made (A) in confidence to a federal, state, or local government official, either directly or indirectly, or to an attorney; and (B) solely for the purpose of reporting or investigating a suspected violation of law; or (ii) is made in a complaint or other document filed in a lawsuit or other proceeding, if such filing is made under seal. Further, an individual who files a lawsuit for retaliation by an employer for reporting a suspected violation of law may disclose the trade secret to the attorney of the individual and use the trade secret information in the court proceeding, if the individual (X) files any document containing the trade secret under seal; and (Y) does not disclose the trade secret, except pursuant to court order.

(d) Representative acknowledges and agrees that any and all trade names and styles used by UAB, including, but not limited to, the terms “United American Bank” and all trademarks, visual designs and logos under which UAB did business (collectively, the “Marks”), are valuable trade names and service marks, the ownership of which will remain with UAB upon the Merger. The undersigned agrees that use by any entity, other than HCC or HBC or one of their respective Subsidiaries, of the Marks in the Counties of Alameda, Contra Costa, Marin, San Benito, San Francisco, San Mateo, and Santa Clara in the State of California would both cause public and customer confusion, and dilute the value of HCC’s and HBC’s investment. Therefore, Representative unconditionally agrees that after the date hereof, he or she will not enter into any business arrangement or agreement, whether formal or informal, directly or indirectly, where the term “United American Bank” or any other Mark, is used.

5. Confidentiality. Representative agrees (a) to hold any and all information regarding this Agreement, the Merger and the Merger Agreement in strict confidence, and (b) not to divulge any information regarding this Agreement, the Merger or the Merger Agreement to any third person (other than Representative’s legal counsel or tax advisors who owe Representative a legal duty of confidentiality with respect to such information), until such time as the Merger has been publicly announced by HCC and UAB, at which time Representative may only divulge such information as has been publicly disclosed by HCC and UAB.

6. Independence of Obligations. The covenants of Representative set forth in this Agreement shall be construed as independent of any other agreement or arrangement between Representative, on the one hand, and HCC and HBC, or their respective Subsidiaries on the other; and the existence of any claim or cause of action by Representative against HCC, HBC, or their respective Subsidiaries shall not constitute a defense to the enforcement of such covenants against Representative.

B-4

7. Termination. This Agreement shall terminate automatically without further action in the event that the Merger Agreement is terminated prior to the Effective Time in accordance with its terms. Unless sooner terminated under the immediately preceding sentence, the obligations of Representative under Section 4(a) of this Agreement shall survive the termination of this Agreement, and the obligations of Representative under Sections 1(b), 2, and 3 of this Agreement shall terminate at the end of the Applicable Period.

8. Specific Performance. Representative acknowledges and agrees that irreparable injury will result to HCC and HBC in the event of a breach of any of the provisions of this Agreement and that HCC and HBC will have no adequate remedy at law with respect thereto. Accordingly, in the event of a material breach of this Agreement, and in addition to any other legal or equitable remedy HCC or HBC may have, HCC and HBC shall be entitled to seek the entry of a preliminary injunction and a permanent injunction (including, without limitation, specific performance) by a court of competent jurisdiction, to restrain the violation or breach thereof by Representative or any affiliates, agents or any other Persons acting for or with Representative in any capacity whatsoever, and Representative submits to the jurisdiction of such court in any such action. In addition, after discussing the matter with Representative, HCC and HBC shall have the right to inform any third party that HCC and HBC reasonably believes to be, or to be contemplating, participating with Representative or receiving from Representative assistance in violation of this Agreement, of the terms of this Agreement and of the rights of HCC and HBC hereunder, and that participation by any such Persons with Representative in activities in violation of Representative’s agreement with HCC and HBC set forth in this Agreement may give rise to claims by HCC and HBC against such third party.

9. Entire Agreement. This Agreement supersedes all prior agreements, written or oral, among the parties hereto with respect to the subject matter hereof and contains the entire agreement among the parties with respect to the subject matter hereof. This Agreement may not be amended, supplemented or modified, and no provisions hereof may be modified or waived, except by an instrument in writing signed by each party hereto. No waiver of any provisions hereof by any party shall be deemed a waiver of any other provisions hereof by any such party, nor shall any such waiver be deemed a continuing waiver of any provision hereof by such party.

10. Attorneys’ Fees. If any action at law or in equity is necessary to enforce or interpret the terms of this Agreement, the prevailing party shall be entitled to reasonable attorneys’ fees, costs and necessary disbursements, in addition to any other relief to which the prevailing party is entitled.

11. Severability. If any provision of this Agreement shall be held by a court of competent jurisdiction to be unreasonable as to duration, activity or subject, it shall be deemed to extend only over the maximum duration, range of activities or subjects as to which such provision shall be valid and enforceable under applicable Law. If any provision of this Agreement shall, for any reason, be held by a court of competent jurisdiction to be invalid, illegal or unenforceable, such invalidity, illegality or unenforceability shall not affect any other provision of this Agreement, but this Agreement shall be construed as if such invalid, illegal or unenforceable provision had never been contained herein.

B-5

12. Notices. All notices and other communications given or made pursuant to this Agreement shall be in writing and shall be deemed effectively given: (a) upon personal delivery to the party to be notified, (b) when sent by confirmed facsimile if sent during normal business hours of the recipient, and if not so confirmed, then on the next business day, (c) four (4) days after having been sent by registered or certified mail, return receipt requested, postage prepaid, or (d) one (1) business day after deposit with an internationally recognized overnight courier, specifying next business day delivery, with written verification of receipt.

(a) In order that HCC and HBC may have and enjoy the full benefit of ownership of UAB and the business it conducts, including its goodwill, following the Effective Time of the Merger, Representative agrees that during the Applicable Period, (i) Representative will not take any affirmative action directly or indirectly to attempt to hire, contact or solicit (other than general solicitations through newspapers or other media of general circulation not targeted at such employees) with respect to hiring, any Person who was an employee of UAB at the Effective Time of the Merger and who becomes an employee of HCC, HBC or any of their respective Subsidiaries in connection with the Merger, or induce or otherwise counsel, advise or knowingly encourage any such Person to leave the employ of HCC, HBC or any of their respective Subsidiaries, and (ii) Representative will not directly or indirectly (A) induce, persuade, encourage or influence or attempt to induce, persuade, encourage or influence any Person who had a business relationship with UAB as of the Effective Time of the Merger and who continues to have a business relationship with HBC, HCC or any of its respective Subsidiaries on or after the Effective Time of the Merger, to discontinue, reduce or restrict such relationship or (B) solicit or target the deposits, loans or other products and services from or to Persons who were depositors, borrowers or customers of UAB as of the Effective Time of the Merger, whether by personal contact, by telephone, by facsimile, by mail or other form of solicitation or communication, or in any other way except for general solicitations that are directed to the general public and not directed specifically to Persons who were depositors, borrowers or customers of UAB as of the Effective Time of the Merger.

(b) Representative acknowledges and agrees that the business conducted by UAB is highly competitive, a significant portion of UAB’s competitiveness and its value as a going enterprise is derived from its workforce and business relationships, and that the covenants made by Representative in this Section 2 are made in consideration of the Merger Consideration Representative will receive in exchange for Representative’s UAB Common Stock, and as a necessary inducement for HCC and HBC to enter into the Merger Agreement and consummate the transactions contemplated thereby. It is the desire and intent of the parties to this Agreement that the provisions of this Section 2 shall be enforced to the fullest extent permissible under the laws and public policies of each jurisdiction in which enforcement is sought. It is expressly understood and agreed that, although Representative, HCC and HBC each consider the restrictions contained in this Section 2 to be reasonable, if a final determination is made by a court of competent jurisdiction or an arbitrator that any restriction contained in this Section 2 is unenforceable against any party, the provisions of this Section 2 shall be deemed amended to apply to the maximum extent as such court may judicially determine or indicate to be enforceable. Representative acknowledges that breach of this Section 2 may cause HCC and HBC irreparable harm and that they may be entitled to entry of an injunction without bond in the event Representative breaches or threatens to breach this Section 2.

3. Confidential Information; Trade Names and Styles.

Notwithstanding the foregoing, “Confidential Information” shall not include any (i) information which is or has become available from an independent third party who learned the information independently and is or was not bound by a confidentiality agreement with UAB, HCC or HBC with respect to such information, (ii) information which Representative independently develops or has developed without reference to such information, or (iii) information readily ascertainable from public, trade or other non-confidential sources (other than as a result, directly or indirectly, of disclosure or other dissemination in violation of an obligation or duty of confidentiality owed to UAB, HCC or HBC).

(b) Notwithstanding any provision of this Agreement to the contrary, Representative may disclose or reveal any information, whether including in whole or part any Confidential Information, that:

C-3

4. Confidentiality. Representative agrees (a) to hold any and all information regarding this Agreement, the Merger and the Merger Agreement in strict confidence, and (b) not to divulge any information regarding this Agreement, the Merger or the Merger Agreement to any third person (other than Representative’s legal counsel or tax advisors who owe Representative a legal duty of confidentiality with respect to such information), until such time as the Merger has been publicly announced by HCC and UAB, at which time Representative may only divulge such information as has been publicly disclosed by HCC and UAB.

5. Independence of Obligations. The covenants of Representative set forth in this Agreement shall be construed as independent of any other agreement or arrangement between Representative, on the one hand, and HCC and HBC, or their respective Subsidiaries on the other; and the existence of any claim or cause of action by Representative against HCC, HBC, or their respective Subsidiaries shall not constitute a defense to the enforcement of such covenants against Representative.

6. Termination. This Agreement shall terminate automatically without further action in the event that the Merger Agreement is terminated prior to the Effective Time in accordance with its terms. Unless sooner terminated under the immediately preceding sentence, the obligations of Representative under Section 3(a) of this Agreement shall survive the termination of this Agreement, and the obligations of Representative under Sections 1(b) and 2 of this Agreement shall terminate at the end of the Applicable Period.

7. Specific Performance. Representative acknowledges and agrees that irreparable injury will result to HCC and HBC in the event of a breach of any of the provisions of this Agreement and that HCC and HBC will have no adequate remedy at law with respect thereto. Accordingly, in the event of a material breach of this Agreement, and in addition to any other legal or equitable remedy HCC or HBC may have, HCC and HBC shall be entitled to seek the entry of a preliminary injunction and a permanent injunction (including, without limitation, specific performance) by a court of competent jurisdiction, to restrain the violation or breach thereof by Representative or any affiliates, agents or any other Persons acting for or with Representative in any capacity whatsoever, and Representative submits to the jurisdiction of such court in any such action. In addition, after discussing the matter with Representative, HCC and HBC shall have the right to inform any third party that HCC and HBC reasonably believes to be, or to be contemplating, participating with Representative or receiving from Representative assistance in violation of this Agreement, of the terms of this Agreement and of the rights of HCC and HBC hereunder, and that participation by any such Persons with Representative in activities in violation of Representative’s agreement with HCC and HBC set forth in this Agreement may give rise to claims by HCC and HBC against such third party.

8. Entire Agreement. This Agreement supersedes all prior agreements, written or oral, among the parties hereto with respect to the subject matter hereof and contains the entire agreement among the parties with respect to the subject matter hereof. This Agreement may not be amended, supplemented or modified, and no provisions hereof may be modified or waived, except by an instrument in writing signed by each party hereto. No waiver of any provisions hereof by any party shall be deemed a waiver of any other provisions hereof by any such party, nor shall any such waiver be deemed a continuing waiver of any provision hereof by such party.

C-4

9. Attorneys’ Fees. If any action at law or in equity is necessary to enforce or interpret the terms of this Agreement, the prevailing party shall be entitled to reasonable attorneys’ fees, costs and necessary disbursements, in addition to any other relief to which the prevailing party is entitled.

10. Severability. If any provision of this Agreement shall be held by a court of competent jurisdiction to be unreasonable as to duration, activity or subject, it shall be deemed to extend only over the maximum duration, range of activities or subjects as to which such provision shall be valid and enforceable under applicable Law. If any provision of this Agreement shall, for any reason, be held by a court of competent jurisdiction to be invalid, illegal or unenforceable, such invalidity, illegality or unenforceability shall not affect any other provision of this Agreement, but this Agreement shall be construed as if such invalid, illegal or unenforceable provision had never been contained herein.

11. Notices. All notices and other communications given or made pursuant to this Agreement shall be in writing and shall be deemed effectively given: (a) upon personal delivery to the party to be notified, (b) when sent by confirmed facsimile if sent during normal business hours of the recipient, and if not so confirmed, then on the next business day, (c) four (4) days after having been sent by registered or certified mail, return receipt requested, postage prepaid, or (d) one (1) business day after deposit with an internationally recognized overnight courier, specifying next business day delivery, with written verification of receipt.

ANNEX D

FORM OF SHAREHOLDER AGREEMENT

This SHAREHOLDER AGREEMENT (“Agreement”) is made and entered into as of January 10, 2018 by and among Heritage Commerce Corp, a California corporation (“HCC”), United American Bank, a California banking corporation (“UAB”), and ATBancorp, Inc., an Iowa corporation (“Shareholder”).

Recitals

A. HCC, Heritage Bank of Commerce, a California banking corporation (“HBC”), and UAB are entering into an Agreement and Plan of Merger and Reorganization (and as it may be amended, the “Merger Agreement”), dated as of the date of this Agreement, pursuant to which UAB will merge with and into HBC (the “Merger”) on the terms and conditions set forth therein and, in connection therewith, each share of UAB Common Stock, Series A Preferred, Series B Preferred, Series D Preferred and Series E Preferred will be converted into the right to receive the consideration set forth in the Merger Agreement. Unless otherwise indicated, capitalized terms used and not defined herein shall have the meanings set forth in the Merger Agreement.

B. As a condition to its willingness to enter into the Merger Agreement, HCC has required that Shareholder enter into, and Shareholder has agreed to enter into, this Agreement.

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

1. Representations and Warranties of Shareholder. Shareholder hereby represents and warrants to HCC as follows:

(a) Authority; No Violation. Shareholder has all necessary power and authority to enter into and perform all of Shareholder’s obligations hereunder. The execution, delivery and performance of this Agreement by Shareholder will not violate any other agreement to which Shareholder is a party, including any voting agreement, shareholders’ agreement, trust agreement or voting trust, any order, arbitration award, judgment or decree to which Shareholder is a party or by which Shareholder is bound, or any statute, rule or regulation to which Shareholder is subject. This Agreement has been duly and validly executed and delivered by Shareholder and constitutes a valid and binding agreement of Shareholder, enforceable against Shareholder in accordance with its terms.

(b) Ownership of Shares. Shareholder is the beneficial owner or record holder of the number of shares of UAB Common Stock, Series A Preferred, Series B Preferred, Series D Preferred Stock and Series E Preferred Stock indicated under Shareholder’s name on the signature page hereto (the “Existing Shares”, and together with any shares of UAB Common Stock, Series A Preferred, Series B Preferred, Series D Preferred Stock and Series E Preferred Stock acquired by Shareholder after the date of this Agreement, the “Shares”) and, as of the date of this Agreement, the Existing Shares constitute all the shares of UAB Common Stock, Series A Preferred, Series B Preferred, Series D Preferred Stock and Series E Preferred Stock owned of record or beneficially by Shareholder. With respect to the Existing Shares, subject to applicable community property laws, Shareholder has sole voting power and sole power to issue instructions with respect to the matters set forth in Section 2 of this Agreement, sole power of disposition, sole power to demand appraisal rights and sole power to engage in actions set forth in Section 2 of this Agreement, with no restrictions on the voting rights, rights of disposition or otherwise, subject to applicable laws and the terms of this Agreement. For purposes of this Agreement, the term “beneficial ownership” shall be interpreted in accordance with Rule 13d-3 under the Securities Exchange Act of 1934, as amended.

D-1

(c) Consents and Approvals. Shareholder has taken all actions necessary to approve the actions contemplated by this Agreement. The execution and delivery of this Agreement by Shareholder does not, and the performance by Shareholder of its obligations under this Agreement and the consummation by it of the transactions contemplated hereby will not, require Shareholder to obtain any consent, approval, authorization or permit of, or to make any filing with or notification to, any Governmental Entity.

(d) Absence of Litigation. There is no suit, action, investigation or proceeding pending or, to the knowledge of Shareholder, threatened against or affecting Shareholder or any of its Affiliates before or by any Governmental Entity that could reasonably be expected to materially impair the ability of Shareholder to perform its obligations hereunder or to consummate the transactions contemplated hereby on a timely basis.

2. Voting Agreement and Agreement Not to Transfer.

(a) Shareholder agrees that at any meeting of the shareholders of UAB which relates to or may impact, either directly or indirectly, the Merger or the Merger Agreement, or in connection with any written consent of the shareholders of UAB, Shareholder will (i) appear at each such meeting or otherwise cause the Shares to be counted as present thereat for purposes of establishing a quorum; and (ii) vote (or cause to be voted), in person or by proxy, or deliver a written consent (or cause a consent to be delivered) covering all the Shares that are owned of record or beneficially by Shareholder or as to which Shareholder has, directly or indirectly, the right to vote or direct the voting: (A) in favor of adoption and approval of the Merger, the Merger Agreement and the transactions contemplated by the Merger Agreement; (B) against any action or agreement that could be expected to result in a breach of any covenant, representation or warranty or any other obligation or agreement of UAB or Shareholder under this Agreement or the Merger Agreement, and (C) except with the prior written consent of HCC, against the following actions (other than the Merger and the transactions contemplated by the Merger Agreement): (1) any extraordinary corporate transactions, such as a merger, consolidation or other business combination involving UAB; (2) any sale, lease or transfer of a material amount of the assets of UAB; (3) any change in the majority of the board of UAB; (4) any material change in the present capitalization of UAB; (5) any amendment of UAB’s Charter Documents; (6) any other material change in UAB’s corporate structure or business; or (7) any other action which is intended, or could reasonably be expected to, impede, interfere with, delay, postpone, discourage or materially adversely affect the Merger. Shareholder shall not enter into any agreement or understanding with any Person prior to the date of termination of this Agreement in accordance with Section 7 to vote or give instructions after the date of termination of this Agreement in accordance with Section 7 in any manner inconsistent with clauses (i) or (ii) of the preceding sentence.

D-2

economic consequence of ownership of the Shares, (iii) take any action that would make any of Shareholder’s representations or warranties contained in this Agreement untrue or incorrect in any material respect or have the effect of preventing or disabling Shareholder from performing Shareholder’s obligations under this Agreement, or (iv) deposit any Shares in a voting trust or grant any proxy (other than to the proxyholder(s) named in the Proxy Statement/Prospectus mailed to shareholders of UAB in connection with the UAB Meeting) or enter into any voting agreement or similar agreement or arrangement with respect to any of the Shares; provided, however, that this Agreement shall not prohibit Shareholder from transferring and delivering Shares to UAB to effect the exercise of an option to purchase UAB Common Stock. Shareholder entering into an agreement with another entity that upon consummation would result in an ATB Change in Control Transaction shall not be deemed to be a “Transfer.”

3. Cooperation. Shareholder agrees that it will not directly or indirectly (i) initiate, solicit, induce or encourage, or take any action to facilitate the making of, any inquiry, offer or proposal which may constitute, or could reasonably be expected to lead to, an Acquisition Proposal, or (ii) participate in any discussions or negotiations regarding any Acquisition Proposal, or furnish, or otherwise afford access, to any Person (other than HCC) to any information or data with respect to UAB or otherwise relating to an Acquisition Proposal.

4. No Solicitation. Shareholder hereby agrees that during the term of this Agreement it shall not, and shall not permit any Representative retained by it to, directly or indirectly, (a) take any of the actions specified in clauses (i)-(iv) of Section 5.04(a) of the Merger Agreement as if it were UAB, (b) agree to release, or release, any Person from any obligation under any existing standstill agreement or arrangement relating to UAB, or (c) participate in, directly or indirectly, a “solicitation” of “proxies” (as such terms are used in the rules of the SEC) or powers of attorney or similar rights to vote, or seek to advise or influence any Person with respect to the voting of, any shares of UAB Common Stock in connection with any vote or other action on any matter of a type described in Section 2(a) of this Agreement, other than to recommend that shareholders of UAB vote in favor of the adoption and approval of the Merger Agreement and the Merger and as otherwise expressly permitted by this Agreement. Shareholder agrees immediately to cease and cause to be terminated any activities, discussions or negotiations conducted before the date of this Agreement with any Persons other than HCC with respect to any possible Acquisition Proposal and will take all necessary steps to inform any Representative retained by it of the obligations undertaken by Shareholder pursuant to this Section 4.

5. Notice of Acquisitions; Proposals Regarding Prohibited Transactions. Shareholder hereby agrees to notify HCC promptly (and in any event within two (2) business days) in writing of the number of any additional shares of UAB Common Stock, Series D Preferred Stock and Series E Preferred Stock or other securities of UAB of which Shareholder acquires beneficial or record ownership on or after the date of this Agreement. Shareholder will comply with the provisions of Section 5.04(c) of the Merger Agreement as if it were UAB.

6. Stop Transfer Order. In furtherance of this Agreement, Shareholder hereby authorizes and instructs UAB to enter a stop transfer order with respect to all of Shareholder’s Shares for the period from the date of this Agreement through the date this Agreement is terminated in accordance with Section 7. UAB agrees that it shall comply with such stop transfer instructions.

7. Term of Agreement; Termination. The term of this Agreement shall commence on the date hereof and terminate at the Effective Time. If the Merger is not consummated and the Merger Agreement is terminated in accordance with its terms (other than as a result of a breach of this Agreement), this Agreement shall be null and void.

D-3

8. Specific Performance. Shareholder acknowledges that it is a condition to the willingness of HCC to enter into the Merger Agreement that Shareholder execute and deliver this Agreement and that it will be impossible to measure in money the damage to HCC if Shareholder fails to comply with the obligations imposed by this Agreement and that, in the event of any such failure, HCC will not have an adequate remedy at law or in equity. Accordingly, Shareholder agrees that injunctive relief or other equitable remedy is the appropriate remedy for any such failure and will not oppose the granting of such relief by a court of competent jurisdiction on the basis that HCC has an adequate remedy at law. Shareholder further agrees that Shareholder will not seek, and agrees to waive any requirement for, the securing or posting of a bond in connection with UAB’s seeking or obtaining such equitable relief. Such injunctive and other equitable remedies are cumulative and shall be HCC’s sole remedy under this Agreement, unless HCC shall have sought and been denied by a court of competent jurisdiction injunctive or other equitable remedies and such denial is other than by reason of violation of this Agreement by HCC.

9. Confidentiality. Shareholder agrees (a) to hold any and all information regarding this Agreement, the Merger and the Merger Agreement in strict confidence, and (b) not to divulge any information regarding this Agreement, the Merger or the Merger Agreement to any third party, until such time as the Merger has been publicly announced by HCC and UAB, at which time Shareholder may only divulge such information as has been publicly disclosed by HCC and UAB.

10. Miscellaneous.

(d) Notices. All notices and other communications hereunder shall be in writing and shall be delivered by hand, by facsimile, or by overnight courier service (except for notices specifically required to be delivered orally). Such communications shall be deemed given to a party (a) at the time and on the date of delivery, if delivered by hand or by facsimile (with, in the case of delivery by facsimile, confirmation of date and time of transmission by the transmitting equipment, and such delivery by facsimile subsequently confirmed with a copy delivered as provided in clause (b) on the next business day); and (b) at the end of the first business day following the date on which sent by overnight service by a nationally recognized courier service (costs prepaid).

ANNEX E

FORM OF NON-SOLICITATION, NON-COMPETITION AND CONFIDENTIALITY AGREEMENT

This NON-SOLICITATION, NON-COMPETITION AND CONFIDENTIALITY AGREEMENT (this “Agreement”), dated as of January 10, 2018, is made by and among Heritage Commerce Corp, a California corporation (“HCC”), Heritage Bank of Commerce, a California state-chartered bank and wholly-owned subsidiary of HCC (“HBC”), and ATBancorp, Inc., an Iowa corporation (“Shareholder”). The Agreement shall become effective at the Effective Time as defined in the Merger Agreement (described below).

Recitals

A. HCC, HBC and United American Bank, a California banking corporation (“UAB”), are entering into an Agreement and Plan of Merger and Reorganization (and as it may be amended, the “Merger Agreement”), dated the date of this Agreement, pursuant to which UAB shall merge with and into HBC (the “Merger”) on the terms and conditions set forth therein. Unless otherwise indicated, capitalized terms used and not defined herein shall have the meanings set forth in the Merger Agreement.

B. Shareholder owns 721,276 shares of UAB Common Stock, 8,700 shares of Series A Preferred, 435 shares of Series B Preferred, 23,000 shares of Series D Preferred and 9,000 shares of Series E Preferred, which will be converted into the right to receive the consideration set forth in the Merger Agreement, and, as a result, Shareholder has a material economic interest in the consummation of the Merger.

C. Following the Merger, the business and operations of HCC, HBC and UAB could be irreparably injured if Shareholder were to undertake certain activities competitive with HCC, HBC or UAB.

D. In order to induce HCC and HBC to enter into the Merger Agreement and consummate the Merger, Shareholder has agreed to enter into and perform this Agreement.

NOW, THEREFORE, in consideration of the transactions contemplated by the Merger Agreement and the benefits to be derived, directly or indirectly, by Shareholder under the Merger Agreement, and in consideration of the mutual covenants contained herein, and for other good and valuable consideration, the receipt, sufficiency and adequacy of which are hereby acknowledged, the parties hereto, intending to be legally bound, agree as follows:

1. Acknowledgments by Shareholder; Support.

(a) Shareholder acknowledges that by virtue of its relationship with UAB, it has considerable expertise in the business operations of UAB and has access to extensive confidential information with respect to UAB and has access to Trade Secrets (as defined below). Shareholder recognizes that HCC and HBC would be irreparably damaged, and HCC’s and HBC’s substantial investment as a result of the acquisition of UAB in the Merger would be materially impaired, if Shareholder were to (i) disclose or make unauthorized use of any Trade Secrets, (ii) take certain actions relative to employees of UAB, or (iii) solicit current or prospective clients, customers, suppliers, agents or certain other Persons. Accordingly, Shareholder expressly acknowledges that it is voluntarily entering into this Agreement and that the terms and conditions of this Agreement are fair and reasonable to Shareholder in all respects.

E-1

(b) Shareholder agrees during the Applicable Period (as defined below) to support and refrain from (i) disparaging the goodwill of HCC, HBC and UAB, (ii) harming the customer and client relationships of HCC, HBC and UAB, and (iii) disparaging the business or banking reputation of HCC, HBC and UAB. For purposes of this Agreement, “Applicable Period” shall mean the period commencing on the Effective Time and ending two (2) years from and after the Effective Time.

2. Non Solicitation.

(a) In order that HCC and HBC may have and enjoy the full benefit of ownership of UAB and the business it conducts, including its goodwill, following the Effective Time of the Merger, Shareholder agrees that during the Applicable Period, (i) Shareholder will not take any affirmative action directly or indirectly to hire, attempt to hire, contact or solicit (other than general solicitations through newspapers or other media of general circulation not targeted at such employees) with respect to hiring, any Person who was an employee of UAB prior to the Effective Time of the Merger and who becomes an employee of HCC, HBC or any of their respective Subsidiaries in connection with the Merger, or induce or otherwise counsel, advise or knowingly encourage any such Person to leave the employ of HCC, HBC or any of their respective Subsidiaries, and (ii) Shareholder will not directly or indirectly (A) induce, persuade, encourage or influence or attempt to induce, persuade, encourage or influence any Person having a business relationship with HBC, HCC or any of its respective Subsidiaries, to discontinue, reduce or restrict such relationship or (B) solicit or target the deposits, loans or other products and services from or to Persons who were depositors, borrowers or customers of UAB on the date of this Agreement, and/or as of the Closing Date, whether by personal contact, by telephone, by facsimile, by mail or other form of solicitation or communication, or in any other way except for general solicitations that are directed to the general public and not directed specifically to Persons who were depositors, borrowers or customers of UAB on the date of this Agreement, or as of the Closing Date.

(b) Shareholder acknowledges and agrees that the business conducted by UAB is highly competitive, a significant portion of UAB’s competitiveness and its value as a going enterprise is derived from its workforce and business relationships, and that the covenants made by Shareholder in this Section 2 are made in consideration of the Merger Consideration Shareholder will receive in exchange for Shareholder’s UAB Common Stock, Series D Preferred Stock and Series E Preferred Stock, and as a necessary inducement for HCC and HBC to enter into the Merger Agreement and consummate the transactions contemplated thereby. It is the desire and intent of the parties to this Agreement that the provisions of this Section 2 shall be enforced to the fullest extent permissible under the laws and public policies of each jurisdiction in which enforcement is sought. It is expressly understood and agreed that, although Shareholder, HCC and HBC each consider the restrictions contained in this Section 2 to be reasonable, if a final determination is made by a court of competent jurisdiction or an arbitrator that any restriction contained in this Section 2 is unenforceable against any party, the provisions of this Section 2 shall be deemed amended to apply to the maximum extent as such court may judicially determine or indicate to be enforceable. Shareholder acknowledges that breach of this Section 2 would cause HCC and HBC irreparable harm and consents to the entry of an injunction without bond in the event Shareholder breaches or threatens to breach this Section 2.

3. Non-Competition. Without the prior written consent of HCC, which may be withheld in HCC’s sole and absolute discretion, during the Applicable Period, Shareholder shall not, directly or indirectly, own, manage, operate, control, engage in or have any interest in any Person, firm, corporation or business (whether as an employee, officer, director, agent, security holder, creditor, consultant or otherwise and other than in the form of a passive investment not to exceed 5% of the outstanding shares of any class of security or of the total outstanding equity of any company) that engages, in any manner, in the provision of Financial Services (as defined below) in the Counties of Alameda, Contra Costa, Marin, San Benito, San Francisco, San Mateo, and Santa Clara in the State of California. For purposes of this

E-2

Agreement, “Financial Services” shall mean the origination, purchasing, selling and servicing of secured or unsecured commercial, real estate, residential, construction, SBA and consumer loans and the solicitation and provision of deposit and investment services and services related thereto; provided, however, that Financial Services shall not include fiduciary and trust services.

4. Trade Secrets; Trade Names and Styles.

(a) Without limiting the generality of Section 2 above, other than for the benefit of UAB, HCC, HBC or their respective Subsidiaries, Shareholder (i) shall make no use, directly or indirectly, of Trade Secrets, or any part thereof, and (ii) shall not disclose Trade Secrets, or any part thereof, to any other Person, and (iii) shall, upon the request of HCC or HBC, deliver all documents, reports, drawings, designs, plans, proposals and other tangible evidence of Trade Secrets now possessed or hereafter acquired by Shareholder to HCC and HBC. For purposes of this Agreement, “Trade Secrets” shall mean (a) all secrets and other confidential information, ideas, concepts, knowledge, know-how, techniques, secret processes, improvements, discoveries, methods, inventions, sales information, financial information, lists of customers and prospective customers, broker lists, potential brokers, rate sheets, market studies, marketing plans, business plans, concepts, strategies or products, as well as all documents, reports, drawings, designs, plans, and proposals otherwise pertaining to same, with respect to UAB, (b) any non-public personal information on any present or past customer or client of UAB, and (c) any other information, however documented, that is a trade secret within the meaning applicable trade secret protection Law. Notwithstanding the foregoing, “Trade Secrets” shall not include any (i) information which is or has become available from an independent third party who learned the information independently and is or was not bound by a confidentiality agreement with respect to such information, or (ii) information readily ascertainable from public, trade or other non-confidential sources (other than as a result, directly or indirectly, of disclosure or other dissemination in violation of an obligation or duty of confidentiality).

(b) Notwithstanding any provision of this Agreement to the contrary, Shareholder may disclose or reveal any information, whether including in whole or part any Trade Secrets, that:

(i) Shareholder is required to disclose or reveal under applicable Law; provided, however, that Shareholder makes a good faith request that the confidentiality of the Trade Secrets be preserved and, to the extent not prohibited by applicable Law and gives, HCC and HBC prompt advance notice of such requirement.

(ii) Shareholder is otherwise required to disclose or reveal by any Governmental Entity; provided, however, that Shareholder makes a good faith request that the confidentiality of the Trade Secrets be preserved and, to the extent not prohibited by applicable Law, gives HCC and HBC prompt advance notice of such requirement.

(iii) In the written opinion of Shareholder’s legal counsel, Shareholder is compelled to disclose or else stand liable for contempt or suffer other censure or penalty imposed by any Governmental Entity; provided, however, that Shareholder makes a good faith request that the confidentiality of the Trade Secrets be preserved and, to the extent not prohibited by applicable Law, gives HCC and HBC prompt advance notice of such requirement.

(c) Shareholder acknowledges and agrees that any and all trade names and styles used by UAB, including, but not limited to, the terms “United American Bank” and all trademarks, visual designs and logos under which UAB did business (collectively, the “Marks”), are valuable trade names and service marks, the ownership of which will remain with UAB upon the Merger. The undersigned agrees that use by any entity, other than HCC or HBC or one of their respective Subsidiaries, of the

E-3

Marks in the Counties of Alameda, Contra Costa, Marin, San Benito, San Francisco, San Mateo, and Santa Clara in the State of California would both cause public and customer confusion, and dilute the value of HCC’s and HBC’s investment. Therefore, Shareholder unconditionally agrees that after the date hereof, it will not enter into any business arrangement or agreement, whether formal or informal, directly or indirectly, where the term “United American Bank” or any other Mark, is used.

5. Release.

(a) Shareholder acknowledges that it is aware of no existing claim or defense, personal or otherwise, or rights of set off whatsoever that Shareholder has against HCC, HBC and/or UAB, except as expressly provided herein. For and in consideration of the consummation of the Merger and the other transactions contemplated by the Merger Agreement, including the Bank Merger, Shareholder, for itself and on behalf of its predecessors, successors, assigns, officers, directors, employees, agents and servants, attorneys and accountants (the “Releasing Parties”), releases, acquits and forever discharges HCC, HBC and UAB and their respective predecessors, successors, assigns, officers, directors, employees, agents and servants, attorneys and accountants, and all persons, natural or corporate, in privity with them or any of them, from any and all known claims or causes of action of any kind whatsoever, at common law, statutory or otherwise, which the Releasing Parties, or any of them, has now existing or that may hereafter arise in respect of any and all agreements and obligations incurred on or prior to the date of this Agreement, or in respect of any event occurring or circumstances existing on or prior to the date of this Agreement; provided, however, that HCC, HBC and UAB shall not be released from any obligations to Shareholder under or arising out of this Agreement or the Merger Agreement (the “Excluded Claims”).

(b) Shareholder further releases HCC, HBC and UAB from any unknown or unanticipated damages arising from the matters set forth in this Agreement (other than the Excluded Claims). Shareholder acknowledges that Shareholder is familiar with, and hereby waives, all rights recognized the provisions of Section 1542 of the California Civil Code, which provides as follows:

A GENERAL RELEASE DOES NOT EXTEND TO CLAIMS WHICH THE CREDITOR DOES NOT KNOW OR SUSPECT TO EXIST IN HIS OR HER FAVOR AT THE TIME OF EXECUTING THE RELEASE, WHICH IF KNOWN BY HIM OR HER MUST HAVE MATERIALLY AFFECTED HIS OR HER SETTLEMENT WITH THE DEBTOR.

Being so familiar and aware, Shareholder expressly waives the effects of California Civil Code §1542, as well as any analogous state or federal statute or regulation. Thus notwithstanding the provisions of California Civil Code §1542, and for the purpose of effecting a full and complete release, Shareholder expressly acknowledges that, except for claims arising out of this Agreement (and the Excluded Claims), this Agreement is intended to include in its effect, without limitation, any and all claims or causes of action that Shareholder does not know of or suspect to exist in Shareholder’s favor as of the date of this Agreement and that this Agreement contemplates that all such claims and causes of action will be extinguished.

E-4

(c) Shareholder shall execute and deliver to HCC and HBC a release of Shareholder with the same provisions as set forth in this Section 5 from the date of this Agreement through the Effective Time if requested to do so by HCC or HBC at or after the Effective Time.

(d) It is expressly understood and agreed that the terms hereof are contractual and not merely recitals, and that the agreements herein contained and the consideration herein transferred is to compromise doubtful and disputed claims, and that no releases made or other consideration given hereby or in connection herewith shall be construed as an admission of liability, all liability being expressly denied by HCC, HBC and UAB. Shareholder hereby represents and warrants that the consideration hereby acknowledged for entering into this Agreement and the transactions contemplated hereby is greater than the value of all claims, demands, actions and causes of action herein relinquished, released, renounced, abandoned, acquitted, waived and/or discharged, and that this Agreement is in full settlement, satisfaction and discharge of any and all such claims, demands, actions, and causes of action that Shareholder may have or be entitled to against HCC, HBC and UAB and their respective predecessors, assigns, legal representatives, officers, directors, employees, attorneys and agents except as set forth in this Section 5.

6. Confidentiality. Shareholder agrees (a) to hold any and all information regarding this Agreement, the Merger and the Merger Agreement in strict confidence, and (b) not to divulge any information regarding this Agreement, the Merger or the Merger Agreement to any third person, until such time as the Merger has been publicly announced by HCC and UAB, at which time Shareholder may only divulge such information as has been publicly disclosed by HCC and UAB.

7. Independence of Obligations. The covenants of Shareholder set forth in this Agreement shall be construed as independent of any other agreement or arrangement between Shareholder or its Subsidiaries, on the one hand, and HCC and HBC, or their respective Subsidiaries on the other; and the existence of any claim or cause of action by Shareholder against HCC, HBC, or their respective Subsidiaries shall not constitute a defense to the enforcement of such covenants against Shareholder.

8. Extension of Term of Restrictive Covenant. If Shareholder violates any restrictive covenant contained in Sections 1 through 4, and if any action to specifically enforce or enjoin the violation of a restrictive covenant contained in Sections 1 through 4 is pending in a court of competent jurisdiction, then the term of such restrictive covenant will be extended by adding to it the number of days that Shareholder’s violation continues and the number of days during which such court action is pending only if and when the court grants specific performance or injunctive relief to the party seeking such relief; provided, however, that the maximum aggregate number of days which may be added to the term of the restrictive covenant as a result of the foregoing is 365 days. If there are both a violation and a pending court action, then the number of days that each continues will be added to the term of such restrictive covenants, but days on which both continue will be counted only once.

9. Termination. This Agreement shall terminate automatically without further action in the event that the Merger Agreement is terminated prior to the Effective Time in accordance with its terms. Unless sooner terminated under the immediately preceding sentence, the obligations of Shareholder under Section 4(a) of this Agreement shall survive the termination of this Agreement, and the obligations of Shareholder under Sections 1(b), 2, and 3 of this Agreement shall terminate at the end of the Applicable Period.

E-5

10. Specific Performance. Shareholder acknowledges and agrees that irreparable injury will result to HCC and HBC in the event of a breach of any of the provisions of this Agreement and that HCC and HBC will have no adequate remedy at law with respect thereto. Accordingly, in the event of a material breach of this Agreement, and in addition to any other legal or equitable remedy HCC or HBC may have, HCC and HBC shall be entitled to the entry of a preliminary injunction and a permanent injunction (including, without limitation, specific performance) by a court of competent jurisdiction, to restrain the violation or breach thereof by Shareholder or any affiliates, agents or any other Persons acting for or with Shareholder in any capacity whatsoever, and Shareholder submits to the jurisdiction of such court in any such action. In addition, after discussing the matter with Shareholder, HCC and HBC shall have the right to inform any third party that HCC and HBC reasonably believes to be, or to be contemplating, participating with Shareholder or receiving from Shareholder assistance in violation of this Agreement, of the terms of this Agreement and of the rights of HCC and HBC hereunder, and that participation by any such Persons with Shareholder in activities in violation of Shareholder’s agreement with HCC and HBC set forth in this Agreement may give rise to claims by HCC and HBC against such third party.

11. Entire Agreement. This Agreement supersedes all prior agreements, written or oral, among the parties hereto with respect to the subject matter hereof and contains the entire agreement among the parties with respect to the subject matter hereof. This Agreement may not be amended, supplemented or modified, and no provisions hereof may be modified or waived, except by an instrument in writing signed by each party hereto. No waiver of any provisions hereof by any party shall be deemed a waiver of any other provisions hereof by any such party, nor shall any such waiver be deemed a continuing waiver of any provision hereof by such party.

12. Attorneys’ Fees. If any action at law or in equity is necessary to enforce or interpret the terms of this Agreement, the prevailing party shall be entitled to reasonable attorneys’ fees, costs and necessary disbursements, in addition to any other relief to which the prevailing party is entitled.

13. Severability. If any provision of this Agreement shall be held by a court of competent jurisdiction to be unreasonable as to duration, activity or subject, it shall be deemed to extend only over the maximum duration, range of activities or subjects as to which such provision shall be valid and enforceable under applicable Law. If any provision of this Agreement shall, for any reason, be held by a court of competent jurisdiction to be invalid, illegal or unenforceable, such invalidity, illegality or unenforceability shall not affect any other provision of this Agreement, but this Agreement shall be construed as if such invalid, illegal or unenforceable provision had never been contained herein.

14. Notices. All notices and other communications hereunder shall be in writing and shall be delivered by hand, by facsimile, or by overnight courier service (except for notices specifically required to be delivered orally). Such communications shall be deemed given to a party (a) at the time and on the date of delivery, if delivered by hand or by facsimile (with, in the case of delivery by facsimile, confirmation of date and time of transmission by the transmitting equipment, and such delivery by facsimile subsequently confirmed with a copy delivered as provided in clause (b) on the next business day); and (b) at the end of the first business day following the date on which sent by overnight service by a nationally recognized courier service (costs prepaid).
