“Transfer” means, with respect to any security, the direct or indirect assignment, sale, transfer, tender, pledge, hypothecation, or the grant, creation or sufferage of an Encumbrance in or upon, or the gift, placement in trust, or the Constructive Sale or other disposition of such security (including transfers by testamentary or intestate succession or otherwise by operation of Law) or any right, title or interest therein (including, but not limited to, any right or power to vote to which the holder thereof may be entitled, whether such right or power is granted by proxy or otherwise), or the record or beneficial

ownership thereof, the offer to make such a sale, transfer, Constructive Sale or other disposition, and each agreement, arrangement or understanding, whether or not in writing, to effect any of the foregoing.

2.Transfer Restrictions. At all times during the period commencing with the execution and delivery of this Agreement and expiring on the Expiration Date, no Shareholder shall, except in connection with the Merger or as the result of the death of such Shareholder, Transfer any of the Shares, or discuss, negotiate, make an offer or enter into an agreement, commitment or other arrangement with respect thereto, unless each Person to which any of such Shares, or any interest in any of such Shares, is or may be Transferred shall have: (a) executed a counterpart of this Agreement, and (b) agreed in writing to hold such Shares (or interest in such Shares) subject to all of the terms and provisions of this Agreement.

3.Right to Vote.

(a)As of the date hereof and for so long as this Agreement remains in effect (including as of the date of the Signature Shareholder Meeting, which, for purposes of this Agreement, includes any adjournment or postponement thereof), except for this Agreement or as otherwise permitted by this Agreement, each Shareholder has full legal power, authority and right to vote all of the Shares then owned of record or beneficially by such Shareholder, in favor of the approval and authorization of the Merger, the Merger Agreement and the other transactions contemplated thereby (collectively, the “Proposed Transaction”) without the consent or approval of, or any other action on the part of, any other Person. Without limiting the generality of the foregoing, no Shareholder has entered into any voting agreement (other than this Agreement) with any Person with respect to any of the Shares, granted any Person any proxy (revocable or irrevocable) or power of attorney with respect to any of the Shares (except for the proxy and power of attorney granted under this Agreement), deposited any of the Shares in a voting trust, or entered into any arrangement or agreement with any Person limiting or adversely affecting such Shareholder’s legal power, authority or right to vote the Shares on any matter. If a Shareholder is the beneficial owner, but not the record holder, of the Shares, such Shareholder agrees to take all actions necessary to cause the record holder and any nominees to vote all of the Shares in favor of the approval and authorization of the Proposed Transaction.

(b)From and after the date hereof, except as otherwise permitted by this Agreement or prohibited by order of a court of competent jurisdiction, no Shareholder will commit any act that could restrict or otherwise adversely affect such Shareholder’s legal power, authority and right to vote all of the Shares then owned of record or beneficially by such Shareholder. Without limiting the generality of the foregoing, except for this Agreement and as otherwise permitted by this Agreement, from and after the date hereof, no Shareholder will enter into any voting agreement with any Person with respect to any of the Shares, grant any Person any proxy (revocable or irrevocable) or power of attorney with respect to any of the Shares, deposit any of the Shares in a voting trust, or otherwise enter into any agreement or arrangement with any Person limiting or adversely affecting such Shareholder’s legal power, authority or right to vote the Shares in favor of the approval of the Proposed Transaction.

4.Agreement to Vote Shares.

(a)Prior to the Expiration Date, at every meeting of the shareholders of Signature called, and at every adjournment or postponement thereof, and on every action or approval by written consent of the shareholders of Signature, each Shareholder (solely in the Shareholder’s capacity as such) will appear at the meeting or otherwise cause the Shares to be present thereat for purposes of establishing a quorum and, to the extent not voted by the Persons appointed as proxies pursuant to Section 5 of this Agreement, vote (i) in favor of approval of the Proposed Transaction, (ii) against the approval or adoption of any proposal made in opposition to, or in competition with, the Proposed Transaction, and (iii) against any of the following (to the extent unrelated to the Proposed Transaction): (A) any merger, consolidation or business combination involving Signature or Signature Bank other than the Proposed Transaction; (B) any sale, lease or transfer of all or substantially all of the assets of Signature or Signature Bank; (C) any reorganization, recapitalization, dissolution, liquidation or winding up of Signature or Signature Bank; or (D) any other action that is intended, or could reasonably be expected to, impede, interfere with, delay, postpone, discourage or adversely affect the consummation of the Proposed Transaction (each of (ii) and (iii), a “Competing Transaction”).

(b)Notwithstanding any other provision of this Agreement, no Shareholder will be required to vote in favor of the Proposed Transaction or in any other manner required pursuant to Section 4(a) (nor will the irrevocable proxy or power of attorney apply) if, and only if, Signature and Heartland amend the Merger Agreement and either (i) such amendment is not approved by the Board of Directors of Signature or a special committee thereof or (ii) such amendment results in the Shareholder receiving different treatment or consideration for such Shareholder’s Shares than is received on a per share basis by the other Shareholders.

5.Grant of Irrevocable Proxy.

(a)Each Shareholder hereby grants to, and appoints, Heartland and each of its executive officers and any of them, in their capacities as officers of Heartland, such Shareholder’s proxy and attorney-in-fact (with full power of substitution and re-substitution), for and in the name, place and stead of such Shareholder, to vote the Shares, to instruct nominees or record holders to vote the Shares, or grant a consent or approval in respect of such Shares in favor of approval and authorization of the Proposed Transaction. The proxy and power of attorney granted by the Shareholder under this Section 5 is irrevocable during the term of this Agreement (to the fullest extent permitted by Law). The proxy and power of attorney granted hereunder will terminate upon the termination of this Agreement.

(b)Each Shareholder represents that any proxies heretofore given in respect of such Shareholder’s Shares that may still be in effect are not irrevocable, and that any such proxies are hereby revoked.

(c)Each Shareholder hereby affirms that the irrevocable proxy set forth in this Section 5 is given in connection with the execution of the Merger Agreement, and that such irrevocable proxy is given to secure the performance of the duties of such Shareholder under this Agreement. Each Shareholder hereby further affirms that the irrevocable proxy is coupled with an interest and may under no circumstances be revoked during the term of this Agreement. Each Shareholder hereby ratifies and confirms all that such irrevocable proxy may lawfully do or cause to be done by virtue hereof.

(d)The attorneys and proxies named in Section 5(a) above may not exercise this irrevocable proxy to vote on any matter except as provided above. Each Shareholder may vote the Shares held by such Shareholder on all other matters.

7.Action in Shareholder Capacity Only.

Each Shareholder is signing this Agreement solely in such Shareholder’s capacity as a record holder and beneficial owner of Shares, and nothing herein shall limit or affect any actions taken in such Shareholder’s capacity as a director, officer, employee or agent of Signature or Signature Bank.

8.Additional Representations and Warranties of Shareholder. Each Shareholder hereby represents and warrants to Heartland as follows: (a) the Shareholder is the beneficial owner or the record owner of the Shares set forth on the signature page of this Agreement below the Shareholder’s signature free and clear of any and all Encumbrances (except for Encumbrances that will be fully discharged prior to the Effective Time); (b) the Shareholder does not beneficially own any shares of Common Stock of Signature other than the Shares set forth on the signature page of this Agreement below the Shareholder’s signature (other than the KSOP Shares and any shares of Common Stock subject to options granted to the Shareholder by Signature); (c) the Shareholder has full power and authority to make, enter into and carry out the terms of this Agreement and to grant the irrevocable proxy as set forth in Section 5; (d) this Agreement has been duly and validly executed and delivered by the Shareholder and constitutes a valid and binding agreement of the Shareholder enforceable against such Shareholder in accordance with its terms, subject to the Remedies Exception; and (e) the execution and delivery of this Agreement and the performance by the Shareholder of such Shareholder’s agreements and obligations hereunder will not result in any breach or violation of or be in conflict with or constitute a default under any term of any agreement, judgment, injunction, order, decree, Law or arrangement to which the Shareholder is a party or by which the Shareholder (or any of such Shareholder’s assets) is bound, except for any such breach, violation, conflict or default which, individually or in the aggregate, would not impair or adversely affect the Shareholder’s ability to perform such Shareholder’s obligations under this Agreement or render inaccurate any of the representations made by such Shareholder herein.

9.Exchange of Shares; Waiver of Rights of Appraisal. If the Merger is consummated in accordance with the terms of the Merger Agreement, the Shares will, pursuant to the terms of the Merger Agreement, be exchanged for the consideration provided in the Merger Agreement. Each Shareholder hereby waives any rights to demand purchase of such Shareholder’s Shares at fair market value as a result of the Merger, or rights to dissent from the Merger, that such Shareholder may have.

  

10.Confidentiality. Each Shareholder recognizes that successful consummation of the transactions contemplated by the Merger Agreement may be dependent upon confidentiality with respect to the matters referred to herein.
