AGREEMENTS

In consideration of the foregoing premises, which are incorporated herein by this reference, and the covenants and agreements of the parties herein contained, and as an inducement to Acquiror and Merger Sub to enter into the Merger Agreement and to incur the expenses associated with the Merger, the parties hereto, intending to be legally bound, hereby agree as follows:

Section 1.              Representations and Warranties.  Each Principal Stockholder represents and warrants that as of the date hereof, he, she or it: (a) owns beneficially and of record the number of shares of Company Common Stock as is set forth opposite such Principal Stockholder’s name on the signature page attached hereto; (b) has the sole, or joint with any other Principal Stockholder, voting power with respect to such shares of Company Common Stock; and (c) has all necessary power and authority to enter into this Agreement, and further represents and warrants that this Agreement is the legal, valid and binding agreement of such Principal Stockholder, and is enforceable against such Principal Stockholder in accordance with its terms, except as such enforcement may be limited by bankruptcy, insolvency, reorganization or other laws affecting creditors’ rights generally and subject to general principles of equity.

Section 2.              Voting Agreement.  Each Principal Stockholder hereby agrees that at any meeting of the Company’s stockholders however called, and any adjournment or postponement thereof, and in any action by written consent of the Company’s stockholders, such Principal Stockholder shall vote, or cause to be voted, all shares of Company Common Stock owned or controlled by him, her or it at the time of such meeting of the Company’s stockholders: (a) in favor of adoption of the Merger Agreement and the approval of the Merger and the other transactions contemplated by the Merger Agreement; (b) against any tender or exchange offer to acquire more than fifteen percent (15%) of the voting power in the Company or any of its subsidiaries, any proposal for a merger, consolidation or other

business combination involving the Company or any of its subsidiaries, or any other proposal or offer to acquire in any manner more than fifteen percent (15%) of the voting power in, or more than fifteen percent (15%) of the business, assets or deposits of, the Company or any of its subsidiaries, other than the transactions contemplated by the Merger Agreement, in each case involving any party other than Acquiror or an affiliate of Acquiror (an “Acquisition Proposal”); and (c) against any action or agreement that could reasonably be expected to result in a material breach of any covenant, representation or warranty or any other obligation of the Company under the Merger Agreement, or in any manner prevent or materially impede, interfere with or delay the Merger, the adoption of the Merger Agreement or the consummation of any of the transactions involving Acquiror and Merger Sub contemplated by the Merger Agreement.

Section 3.              Additional Covenants.  Except as required by law, each Principal Stockholder agrees that he, she or it will:

(a)                                 not engage in any activities, discussions or negotiations with any persons or entities other than Acquiror with respect to any Acquisition Proposal;

(b)                                 not vote or execute any written consent to rescind or amend in any manner any prior vote or written consent to approve or adopt the Merger Agreement or any of the transactions contemplated thereby;

(c)                                  use his, her or its best efforts to cause any necessary meeting of the Company’s stockholders to be duly called and held, or any necessary consent of stockholders to be obtained, for the purpose of approving or adopting the Merger Agreement and the transactions contemplated thereby;

(d)                                 cause each of his, her or its affiliates to cooperate fully with Acquiror in connection with the Merger Agreement and the transactions contemplated thereby; and

(e)                                  execute and deliver such additional instruments and documents and take such further action as may be reasonably necessary to effectuate and comply with his, her or its respective obligations under this Agreement.

Section 4.              No Dissent.  Each Principal Stockholder hereby waives, and agrees that he, she or it will not exercise, any rights of dissent or appraisal provided under the Merger Agreement, any applicable laws (including the General Corporation Law of the State of Delaware (the “DGCL”)) or otherwise in connection with the approval of the Merger or any of the other transactions contemplated by the Merger Agreement.

Section 5.              Termination.  Notwithstanding any other provision of this Agreement, this Agreement shall automatically terminate on the earlier of:  (a) the second anniversary of the date hereof, (b) the date of termination of the Merger Agreement in accordance with its terms; and (c) the date, if any, on which the Company publicly discloses that the board of directors of the Company (the “Company Board”) has withdrawn, qualified or adversely modified its recommendation to the stockholders of the Company that the Company’s stockholders vote in favor of the adoption of the Merger Agreement, in each case because the Company Board has determined in good faith, after consultation with outside counsel, that to, or to continue to, recommend the Merger Agreement to the Company’s stockholders would result in a violation of its fiduciary duties under applicable law.  In addition, each Principal Stockholder’s obligations under Section 2 and Sections 3(a) — (c) of this Agreement shall terminate upon the adoption of the Merger Agreement by the Company’s stockholders in accordance with the requirements of the DGCL; provided such Principal Stockholder has complied in all respects with its obligations under Sections 2 and 3.

Section 6.              Amendment and Modification.  This Agreement may be amended, modified or supplemented at any time by the written approval of such amendment, modification or supplement by Acquiror, Merger Sub and all of the Principal Stockholders.

Section 7.              Entire Agreement.  This Agreement evidences the entire agreement among the parties hereto with respect to the matters provided for herein and there are no agreements, representations or warranties with respect to the matters provided for herein other than those set forth herein and in the Merger Agreement and any written agreements related thereto.  Except for the Merger Agreement, this Agreement supersedes any agreements among any of the Principal Stockholders and Acquiror or Merger Sub concerning the acquisition, disposition or control of any shares of Company Common Stock or shares of Preferred Stock, no par value per share, of the Company (the “Company Preferred Stock” and, together with the Company Common Stock, the “Company Capital Stock”).

Section 8.              No Economic Benefit; Absence of Control.  Nothing contained in this Agreement shall be deemed to vest in Acquiror any direct or indirect ownership or incidence of ownership of or with respect to any of the Company Capital Stock.  All rights, ownership and economic benefits of and relating to the Company Capital Stock shall remain and belong to the applicable stockholder and Acquiror shall have no power or authority to direct any stockholder in the voting of any of the Company Capital Stock or the performance by any stockholder of his, her or its duties or responsibilities as a stockholder of the Company, except as otherwise provided herein.  Subject to any specific provisions of this Agreement, it is the intent of the parties to this Agreement that neither Acquiror nor Merger Sub, by reason of this Agreement, shall be deemed (until consummation of the transactions contemplated by the Merger Agreement) to control, directly or indirectly, the Company and shall not exercise, or be deemed to exercise, directly or indirectly, a controlling influence over the management or policies of the Company.  For the avoidance of doubt, this Agreement is a voting and support agreement only, and is not to be interpreted as a written consent to the Merger or as granting Acquiror a proxy to vote the Company Common Stock subject to this Agreement.

Section 9.              Informed Action.  Each Principal Stockholder acknowledges that he, she or it has had an opportunity to be advised by counsel of his, her or its choosing with regard to this Agreement and the transactions and consequences contemplated hereby.  Each Principal Stockholder further acknowledges that he, she or it has received a copy of the Merger Agreement and is familiar with its terms.

Section 10.       Severability.  The parties agree that if any provision of this Agreement shall under any circumstances be deemed invalid or inoperative, this Agreement shall be construed with the invalid or inoperative provisions deleted and the rights and obligations of the parties shall be construed and enforced accordingly.

Section 11.       Notices.  All notices, requests, claims, demands, and other communications hereunder shall be in writing and shall be deemed to have been given:  (a) when delivered by hand (with written confirmation of receipt); (b) when received by the addressee if sent by a nationally recognized overnight courier (receipt requested); (c) on the date sent by facsimile or e-mail of a portable data file (pdf) of the document (with confirmation of transmission) if sent during normal business hours of the recipient, and on the next business day if sent after normal business hours of the recipient; or (d) on the fifth (5th) day after the date mailed, by certified or registered mail, return receipt requested, postage prepaid.  Such communications must be sent to the respective parties at the following addresses (or at such other address for a party as shall be specified in a notice given in accordance with this Section 11):

Section 12.       Counterparts; Facsimile/PDF Signatures.  This Agreement may be executed in counterparts, each of which shall be deemed an original, but all of which together shall constitute one and the same instrument.  This Agreement may be executed and accepted by facsimile or portable data file (pdf) signature and any such signature shall be of the same force and effect as an original signature.

Section 13.       Governing Law; Venue; Waiver of Jury Trial.  All questions concerning the construction, validity and interpretation of this Agreement and the performance of the obligations imposed by this Agreement shall be governed by the internal laws of the State of Delaware applicable to Contracts made and to be performed in such state without regard to conflicts of laws.  Each party hereby irrevocably submits to the exclusive jurisdiction of the state and federal courts located in Illinois solely in respect of the interpretation and enforcement of the provisions of this Agreement and of the documents referred to in this Agreement, and in respect of the transactions contemplated hereby, and hereby waives, and agrees not to assert, as a defense in any action, suit or proceeding for the interpretation or enforcement hereof or of any such document, that it is not subject thereto or that such action, suit or proceeding may not be brought or is not maintainable in said court or that the venue thereof may not be appropriate or that this Agreement or any such document may not be enforced in or by such court, and the parties hereto irrevocably agree that all claims with respect to such action or proceeding shall be heard and determined in such court.  The parties hereby consent to and grant any such court jurisdiction over the person of such parties and agree that mailing of process or other papers in connection with any such action or proceeding in the manner provided under Section 11 or in such other manner as may be permitted by applicable law shall be valid and sufficient service thereof.  EACH PARTY ACKNOWLEDGES AND AGREES THAT ANY CONTROVERSY WHICH MAY ARISE UNDER THIS AGREEMENT IS LIKELY TO INVOLVE COMPLICATED AND DIFFICULT ISSUES, AND

EACH PARTY CERTIFIES AND ACKNOWLEDGES THAT (i) NO REPRESENTATIVE, AGENT OR ATTORNEY OF ANY OTHER PARTY HAS REPRESENTED, EXPRESSLY OR OTHERWISE, TO IT THAT SUCH OTHER PARTY WOULD NOT, IN THE EVENT OF LITIGATION, SEEK TO ENFORCE THE FOREGOING WAIVER, (ii) EACH PARTY UNDERSTANDS AND HAS CONSIDERED THE IMPLICATIONS OF THIS WAIVER, (iii) EACH PARTY MAKES THIS WAIVER VOLUNTARILY AND (iv) EACH PARTY HAS BEEN INDUCED TO ENTER INTO THIS AGREEMENT BY, AMONG OTHER THINGS, THE MUTUAL WAIVERS AND CERTIFICATIONS SET FORTH HEREIN.
