AGREEMENT

To implement the foregoing and in consideration of the mutual agreements contained herein, the parties agree as follows:

1. Voting, Proxies, Etc.

(a)

Agreement to Vote. Each Stockholder hereby agrees, severally and not jointly, that, from and after the date hereof and until this Agreement shall have been terminated in accordance with Section 7:

(i)

At any meeting of the stockholders of the Company called for purposes that include approval of the Merger and the Merger Agreement, however called, or at any adjournment thereof, or in connection with any written consent of the stockholders of the Company or in any other circumstances in which such Stockholder is entitled to vote, consent or give any other approval with respect to the Merger and the Merger Agreement, such Stockholder shall vote (or cause to be voted) such Stockholder's Shares (to the extent such Shares are entitled to be voted and are not so voted pursuant to the proxy granted in Section 1(b)) in favor of adoption of the Merger Agreement and the approval of the terms thereof and each of the other actions contemplated by the Merger Agreement and this Agreement.

(ii)

At any meeting of the stockholders of the Company, however called, or at any adjournment thereof, or in connection with any written consent of the stockholders of the Company, or in any other circumstances in which such Stockholder is entitled to vote, consent or give any other approval, such Stockholder shall vote (or cause to be voted) such Stockholder's Shares (to the extent such Shares are entitled to be voted) against the following actions:

(1): any proposal that would result in a breach by the Company of the Merger Agreement or by the Stockholder hereunder; or
(2): any action or agreement that is intended to, or would be reasonably likely to, impede, interfere with, delay, postpone or attempt to discourage the Merger, including, but not

limited to: (A) the adoption by the Company of any Acquisition Transaction; (B) any amendment of the Company's certificate of incorporation, certificates of designation or by-laws; (C) any material change in the present capitalization or dividend policy of the Company; or (D) any other material change in the Company's corporate structure or business.

(b): Proxies. As security for the agreements of the Stockholder provided for herein, each Stockholder hereby grants to Merger Sub a proxy for the term of this Agreement to vote such Stockholder's Shares as indicated in Section 1(a) above. Such Stockholder agrees that this proxy shall be irrevocable during the term of this Agreement and coupled with an interest and each of the Stockholder and Merger Sub will take such further action or execute such other instruments as may be necessary to effectuate the intent of this proxy and such Stockholder hereby revokes any proxy previously granted by such Stockholder with respect to such Stockholder's Shares.
(c): Transfer Restrictions. Each Stockholder agrees not to (i) sell, transfer, pledge, encumber, assign or otherwise dispose of or hypothecate (including by gift or by contribution or distribution to any trust or similar instrument (collectively, "Transfer")), or enter into any contract, option or other arrangement or understanding (including any profit sharing arrangement) with respect to the Transfer of, any of such Stockholder's Shares other than pursuant to the terms hereof and the Merger Agreement, (ii) enter into any voting arrangement or understanding with respect to such Stockholder's Shares (other than this Agreement), whether by proxy, voting agreement or otherwise, or (iii) take any action that could make any of its representations or warranties contained herein untrue or incorrect in any material respect or would have the effect of preventing or disabling such Stockholder from performing any of its obligations hereunder. For the avoidance of doubt, (i) nothing herein shall be construed to prohibit the conversion by any stockholder of such Shareholder's Series A Preferred into Company Common Stock or exercise by any Stockholder of warrants to acquire any Company Common Stock, Series A Preferred or Series B Preferred and (ii) any shares of Company Common Stock, Series A Preferred or Series B Preferred obtained by a Stockholder upon such conversion or exercise shall be included in such Stockholder's Shares.
(d): Appraisal Rights. Each Stockholder hereby irrevocably waives any and all rights which it may have as to appraisal, dissent or any similar or related matter with respect to the Merger.
(e): No Solicitation. Each Stockholder will not (and DLJ Merchant Banking, Inc. will not directly or indirectly) take any action that if taken by the Company would be a breach of Section 4.3(a) of the Merger Agreement (disregarding for this purpose the proviso to the first sentence of such Section 4.3(a), but subject to the last sentence of this Section 1(e)). Each Stockholder shall promptly advise Parent and Merger Sub orally and in writing of the receipt by it of any Acquisition Proposal or any inquiry from any Person other than Parent regarding a potential acquisition of the Shares, the material terms and conditions of such Acquisition Proposal or inquiry, and the identity of the Person making any such Acquisition Proposal or inquiry. Such Stockholder (or DLJ Merchant Banking, Inc.) will keep Parent and Merger Sub informed on a current basis with respect to material developments relating to any such Acquisition Proposal or inquiry or any material modification or proposed modification thereto. Nothing in this Section shall restrict the activities of any individual (whether or not an affiliate of any Stockholder (or DLJ Merchant Banking, Inc.)) in his or her capacity as a director or officer of the Company. Notwithstanding the foregoing, if the Board of Directors of the Company determines in good faith that a Qualified Acquisition Proposal made by any Person or Persons is reasonably likely to result in a Superior Proposal, each Stockholder (and DLJ Merchant Banking, Inc.) shall be permitted to engage in discussions and negotiations with, and furnish nonpublic information regarding the Acquired Corporations to, such Person or Persons if the Board of Directors of the Company has concluded in good faith, after consultation with its outside legal counsel, that such action is required in order for the Board of Directors of the Company to comply with its fiduciary obligations to the Company's stockholders under applicable Legal Requirements and the other requirements of the proviso to the first sentence of Section 4.3(a) of the Merger Agreement have been satisfied.

2. Option.

(a)

Each Stockholder hereby grants to Merger Sub an irrevocable option to purchase that number of shares of Company Common Stock as is set forth under the column "Option Shares" on Exhibit I (as to such Stockholder, such Stockholders' "Option Shares"), on the terms and subject to the conditions set forth herein (the "Option").

(b)

The Option may be exercised by Merger Sub, as a whole and not in part, at any time during the period commencing upon (x) the termination of the Merger Agreement pursuant to Section 9.1(f) thereof and (y) ending 96 hours after such termination.

(c)

If Merger Sub wishes to exercise the Option, Merger Sub shall send a written notice to each Stockholder of its intention to exercise the Option, specifying the place, and, if then known, the time and the date (the "Option Closing Date") of the closing (the "Option Closing") of the purchase. The Option Closing Date shall occur on the fifth business day (or such longer period as may be required by applicable Legal Requirements) after the later of (i) the date on which such notice is delivered and (ii) the satisfaction of the conditions set forth in Section 2(f).

(d)

At the Option Closing, each Stockholder shall deliver to Merger Sub (or its designee) all of the Option Shares by delivery of a certificate or certificates evidencing its Option Shares in the denominations designated by Merger Sub in its exercise notice delivered pursuant to Section 2(c), duly endorsed to Merger Sub or accompanied by stock powers duly executed in favor of Merger Sub, with all necessary stock transfer stamps affixed.

(e)

At the Option Closing, Merger Sub shall deliver, and Parent shall cause Merger Sub to deliver to each Stockholder in respect of each Stockholder's Option Shares the purchase price per Option Share, as defined in the next sentence. The purchase price per Option Share shall be, in respect of each share of Company Common Stock constituting an Option Share, $6.5992 per share (the "Option Shares Purchase Price").

(f)

The Option Closing shall be subject to the satisfaction of (or, in the case of subparagraph (iii), the waiver by Merger Sub of) each of the following conditions:

(i): No temporary restraining order, preliminary or permanent injunction or other order preventing the consummation of the purchase and sale of the Shares pursuant to the exercise of the Option shall have been issued by any court of competent jurisdiction or any other Governmental Body of a Relevant Jurisdiction and shall remain in effect, and there shall not be any Legal Requirement of a Relevant Jurisdiction enacted, adopted or deemed applicable to the consummation of the purchase and sale of the Shares pursuant to the exercise of the Option that makes such consummation illegal or otherwise prohibits consummation of the Option;
(ii): any waiting period applicable to the consummation of the purchase and sale of the Shares pursuant to the exercise of the Option under any applicable Antitrust Laws or other Legal Requirements of a Relevant Jurisdiction shall have expired or been terminated; and
(iii): the purchase and sale of each Stockholder's Option Shares shall occur concurrently.

If the Option Closing shall not occur within 90 days after the exercise of the Option then, unless such failure results from a Stockholder's failure to comply with this Agreement, the Option and this Agreement shall terminate and be of no further force or effect.

(g): If, after purchasing the Option Shares pursuant to the Option, (x) Merger Sub or any of its affiliates has not acquired, or consummated a tender or exchange offer for, the remaining Company Common Stock or consummated a merger or consolidation with the Company and (y) Merger Sub or any of its affiliates receives any cash or non-cash consideration in respect of some or all of the Option Shares (the "Transferred Shares") in connection with (or during the pendency of) a Third Party Business Combination (as defined below) during the period commencing on the date of the Option Closing and ending on the six month anniversary thereof, Merger Sub shall promptly pay over to the Stockholders (to be allocated among them pro rata), in cash as an addition to the aggregate Option Shares Purchase Price for all Option Shares, 50% of the excess, if any, of the value of such consideration received over

the aggregate Option Shares Purchase Price paid for the Transferred Shares; provided that, (i) with respect to any of the consideration received by Merger Sub or such affiliates for the Transferred Shares consisting of securities listed on a national securities exchange or traded on the Nasdaq National Market, the per share value of such consideration shall be equal to the closing price per share of such securities listed on such national securities exchange or the Nasdaq National Market on the date such transaction is consummated, and (ii) with respect to any consideration received by Merger Sub or such affiliates for the Transferred Shares in a form other than securities so listed, the per share value shall be determined in good faith as of the date such transaction is consummated by Merger Sub and the Stockholders, or, if Merger Sub and the Stockholders cannot reach agreement, by a nationally recognized investment banking firm reasonably acceptable to the parties. The term "Third Party Business Combination" means the occurrence of any of the following events: (A) the Company, or more than 50% of the outstanding shares of the Company Common Stock, is acquired by merger or otherwise by any Person other than Parent, Merger Sub, Stockholder or their respective affiliates (a "Third Party"); or (B) a Third Party acquires all or substantially all of the assets of the Company and its subsidiaries, taken as a whole; provided, however, that in no event will any transaction in which shares of the Company Common Stock or any of its assets are sold or transferred directly or indirectly in connection with or as a part of a sale or other transaction involving a sale, merger or other similar transaction of Parent or any of its material assets or business constitute a Third Party Business Combination, and in no event will a sale of any division, line of business or similar unit of the Company and its subsidiaries (other than a sale of all or substantially all of the assets of the Company and its subsidiaries) constitute a Third Party Business Combination.

(h): If, within six months after purchasing the Option Shares pursuant to the Option, Merger Sub or any of its affiliates consummates a tender or exchange offer for the remaining Company Common Stock or consummates a merger or consolidation with the Company, in either case at a price per share of Company Common Stock in excess of the Option Shares Purchase Price, Merger Sub shall pay over to the Stockholders (to be allocated among them pro rata) promptly after the consummation of the first such tender offer, exchange offer, merger or consolidation to occur, as an addition to the aggregate Option Shares Purchase Price for all Option Shares, an amount in cash equal to 50% of the product of (i) the number of Option Shares sold to Merger Sub by all Stockholders pursuant to the Option and (ii) the excess, if any, of the price per share of Company Common Stock paid in such transaction over the Option Shares Purchase Price (for purposes of calculating the price per share paid in such transaction with respect to (i) any such consideration consisting of securities listed on a national securities exchange or traded on the Nasdaq National Market, the per share value of such consideration shall be equal to the closing price per share of such securities listed on such national securities exchange or the Nasdaq National Market on the date such transaction is consummated, and (ii) any consideration other than securities so listed, the per share value shall be determined in good faith as of the date such transaction is consummated by Merger Sub and the Stockholder, or, if Merger Sub and the Stockholders cannot reach agreement, by a nationally recognized investment banking firm reasonably acceptable to the parties).
(i): If, after the Option expires unexercised, (x) the Stockholders or any of their respective affiliates have not acquired, or consummated a tender or exchange offer for, the remaining Company Common Stock or consummated a merger or consolidation with the Company and (y) a Stockholder receives any cash or non-cash consideration in respect of some or (subject to the final sentence of this Section 2(i)) all of its Company Common Stock (the "Transferred Stock") in connection with (or during the pendency of) a Third Party Business Combination during the period commencing on the expiration of the period specified in Section 2(b) and ending on the six month anniversary thereof, such Stockholder shall promptly pay over to Merger Sub an amount in cash equal to 50% of the excess, if any, of the value of such consideration received over the product of (A) the Option Shares Purchase Price and (B) the number of shares of Transferred Stock sold by it; provided that, (i) with respect to consideration received by the Stockholder for the Transferred Stock consisting of securities listed on a national securities exchange or traded on the Nasdaq National Market, the per share value of such consideration shall be equal to the closing price per share of such securities listed on such national securities exchange or the Nasdaq National Market on the date such transaction is consummated, and

(ii) with respect to consideration received by the Stockholder for the Transferred Stock consisting of a form other than securities so listed, the per share value shall be determined in good faith as of the date such transaction is consummated by Merger Sub and the Stockholder, or, if Merger Sub and the Stockholder cannot reach agreement, by a nationally recognized investment banking firm reasonably acceptable to the parties. For purposes of calculating the consideration payable to Merger Sub pursuant to this Section 2(i), the number of shares of Transferred Stock sold by any Stockholder shall not exceed the number of such Stockholder's Option Shares and, if the Stockholder sells a greater number of shares of Company Common Stock under the circumstances contemplated by clause (y) of the preceding sentence, such sales shall be taken into account in the order in which they occur until the number of shares of Company Common Stock subject to those sales equals the number of such Stockholder's Option Shares and then no further sharing under this Section 2(i) shall be required.

(j): If, after the date hereof, the Company Common Stock or the Parent Subordinated Voting Shares are combined into a smaller number of shares or split or subdivided into a greater number of shares, the determinations in this Section 2 shall be proportionately adjusted so that the economic consequences of the transactions contemplated hereby are not affected by such action.
