RECITALS

Parent, Merger Subsidiary and the Company are entering into an Agreement and Plan of Merger of even date herewith (the “Merger Agreement”) which provides, among other things, that Merger Subsidiary will make a cash tender offer (the “Offer”) for all of the issued and outstanding shares of Company Common Stock (as defined below) and, following the consummation of the Offer, will merge with and into the Company (the “Merger”), in each case upon the terms and subject to the conditions set forth in the Merger Agreement.

The Stockholder is the beneficial owner (as defined in Rule 13d-3 under the Exchange Act) of such number of securities of the Company as indicated on the Schedule I to this Agreement; and

In order to induce Parent and Merger Subsidiary to enter into the Merger Agreement, the Stockholder is entering into this Agreement.

NOW, THEREFORE, intending to be legally bound, the parties hereto agree as follows:

Section 1. Certain Definitions.

For purposes of this Agreement:

(a) “Company Common Stock” shall mean the common stock, par value $0.01 per share, of the Company.

(b) “Company Warrants” shall mean warrants to purchase 741,716 shares of Company Common Stock at an exercise price of $4.25 per share.

(h) Capitalized terms not otherwise defined herein shall have the respective meanings ascribed to them in the Merger Agreement.

Section 2. Transfer of Subject Securities.

(a) Transferee of Subject Securities to be Bound by this Agreement. The Stockholder agrees that, except as may be provided herein, during the period from the date of this Agreement through the Expiration Date, the Stockholder shall not cause or permit any Transfer of any of the Subject Securities to be effected; provided, that nothing in this Agreement shall prohibit the Stockholder from Transferring Subject Securities to Merger Subsidiary pursuant to Section 3 hereof. Parent and Merger Subsidiary acknowledge and agree that the Stockholder has previously entered into a voting agreement with Wiser Investment Company, LLC (“WIC”) granting WIC certain voting

rights with respect to the Subject Securities and that WIC and Stockholder have in connection with a loan previously pledged Subject Securities to Management Resources Group, LLC (“MRG”) pursuant to a pledge agreement previously entered into by such parties and that the existence of such voting and pledge agreements and the continuing compliance by the parties thereto with such agreements shall not be deemed a Transfer in contravention of this Section 2(a); provided, however, that notwithstanding the foregoing no Transfer shall be permitted under such agreements if such Transfer would adversely affect the right and power of the Stockholder to tender the Subject Securities in the Offer or otherwise comply with its obligations under this Agreement unless the transferee in any such Transfer shall (i) execute a counterpart of this Agreement and (ii) agree to hold such Subject Securities subject to all of the terms and provisions of this Agreement and be treated as a Stockholder hereunder. If Section 3(c) applies, the Stockholder agrees that during the period from the Expiration Date through the date the provisions of Section 3(c) terminate pursuant to Section 9(m), the Stockholder shall not cause or permit any Transfer of any of the Subject Securities to be effected unless the Person to whom such Subject Securities are Transferred shall have: (i) executed a counterpart of this Agreement and (ii) agreed to hold such Subject Securities subject to the terms and provisions of Section 3(c) hereof and be treated as a Stockholder thereunder.

(b) No Transfer of Voting Rights. The Stockholder shall ensure that, except for voting agreements in favor of WIC existing on the date hereof and except for the Stockholders Agreement dated May 26, 2000 among the Company, the Stockholder and certain other stockholders of the Company (the “Stockholders Agreement”), during the period from the date of this Agreement through the Expiration Date: (a) none of the Subject Securities Owned by the Stockholder is deposited into a voting trust; and (b) no proxy is granted, and no voting agreement or similar agreement is entered into, with respect to any of the Subject Securities Owned by the Stockholder.

Section 3. Tender of Subject Securities.

The Stockholder agrees:

(a) to tender the Company Common Stock Owned by the Stockholder into the Offer promptly, and in any event no later than the tenth Business Day following the commencement of the Offer, or, if any Stockholder has not received the Offer Documents by such time, within five Business Days following receipt of such documents but in any event prior to the date of expiration of such Offer, in each case, free and clear of any liens, claims, options, rights of first refusal, co-sale rights, charges or other encumbrances (collectively, “Liens”) other than the Lien of MRG which shall be released upon payment by Parent or Merger Subsidiary of a portion of the Offer Price to be identified by Stockholder and confirmed by MRG in Stockholder’s letter of transmittal accompanying tendered Subject Securities (it being agreed that the Stockholder will cause such Lien upon payment for the Subject Securities to be released) and (ii) not to withdraw any Company Common Stock so tendered so long as there is no decrease in the Offer Price and the Offer Price is payable in cash. The Stockholder shall have no obligations or liabilities to Parent or Merger Subsidiary under this Section 3(a) at any time after the Expiration Date. If the Stockholder acquires additional Subject Securities after the date hereof, the Stockholder shall tender (or cause the record holder to tender) such Subject

Securities on or before the tenth Business Day following the commencement of the Offer, or, if later, on or before the fifth Business Day after such acquisition but in any event prior to the date of expiration of such Offer. The Stockholder acknowledges and agrees that the obligation of Merger Subsidiary to accept for payment and pay for any Subject Securities in the Offer is subject to the terms and conditions of the Offer (as described in the Merger Agreement). Parent and Merger Subsidiary acknowledge that the Stockholder’s obligation to sell any Subject Securities to Merger Subsidiary and the release of the Lien of MRG and termination of any voting agreement in favor of WIC is expressly conditioned upon Merger Subsidiary’s acceptance and payment for the Subject Securities in the Offer pursuant to the terms of the Offer as the same may be amended from time to time, consistent with the terms of this Agreement and the Merger Agreement;

(b) to permit Parent, Merger Subsidiary and the Company to publish and disclose in the Offer Documents and Schedule 14D-9 and, if approval of the stockholders of the Company is required under applicable law, the Proxy Statement (including all documents and schedules filed with the SEC) and any similar filing required by applicable law in connection with the transactions contemplated by the Offer and Merger Agreement, the Stockholder’s identity and ownership of the Subject Securities and the nature of the Stockholder’s commitments, arrangements and understandings under this Agreement;

(c) in the event (i) the Merger Agreement is terminated pursuant to Sections 8.01(e), 8.01(f) or 8.01(h) of the Merger Agreement (in the case of 8.01(h), only if the Minimum Condition had not been satisfied and an Acquisition Proposal existed or had been previously announced prior to the termination of the Merger Agreement), and (ii) within nine months following such termination the Stockholder (A) receives consideration in respect of some or all of the Subject Securities in connection with the consummation of an Acquisition Proposal or (B) makes a bona fide sale of some or all of its Subject Securities to a third party, to pay Parent an amount in immediately available funds by wire transfer to a bank account designated by Parent equal to 30.78% multiplied by the difference between (i) the aggregate fair value of the consideration received by the Stockholder pursuant to such Acquisition Proposal or third party sale, as applicable, and (ii) the aggregate cash consideration that would have been received by the Stockholder pursuant to the Offer based on the initial Offer Price of $10.60 per share with respect to the Subject Securities sold in connection with such Acquisition Proposal or third party sale, as applicable (or in the case of Subject Securities other than Company Common Stock, the amount of cash consideration that would have been received had such Subject Securities been exercised for Company Common Stock prior to the expiration of the Offer net of the applicable exercise price). Such payment to Parent shall be made as follows: (i) if the consideration paid to the Stockholder is cash, immediately following the consummation of such Acquisition Proposal or third party sale or (ii) if the consideration paid to the Stockholder consists of marketable securities, within ten Business Days following consummation of such Acquisition Proposal or third party sale. In the event the consideration received by the Stockholder in respect of an Acquisition Proposal or third party sale, as applicable, consists of marketable securities, the fair value of such securities shall be determined based on the closing market price of such securities on the principal securities exchange or other trading market for such securities on the Business

Day immediately preceding the closing date of such Acquisition Proposal or third party sale. In the event the consideration received by the Stockholder in respect of an Acquisition Proposal or third party sale, as applicable, consists of non-marketable securities or other property, the fair value of such consideration shall be determined by a nationally recognized investment banking firm selected by Stockholder that has not provided services to Stockholder or its affiliates during the prior five years and is reasonably acceptable to Parent as soon as possible after the closing of such Acquisition Proposal, and the fair value determination of such firm shall be binding upon the parties. In the event the consideration received by the Stockholder consists of any non-marketable securities or other property, the Stockholder shall pay Parent its good faith estimate (the “Estimated Payment”) of the amount owed pursuant to this Section 3(c) in respect of such consideration within ten Business Days following consummation of the Acquisition Proposal or third party sale, as applicable. Following the determination of the fair value of any non-marketable securities or other property (as described above), the Stockholder or Parent shall promptly pay the other party in immediately available funds by wire transfer to a bank account designated by the payee party an amount equal to the difference between the Estimated Payment and finally determined amount owing to Parent under Section 3(c) (with Parent receiving payment to the extent such amount exceeds the Estimated Payment and the Stockholder receiving payment to the extent the Estimated Payment exceeds such amount). In addition, if Stockholder makes a bona fide sale of some or all of its Subject Securities to a third party at a time when the Company is then a party to an agreement that provides for an Acquisition Proposal (which agreement has not then been terminated pursuant to its terms), then if such Acquisition Proposal is consummated (or if that Acquisition Proposal is not consummated because another Acquisition Proposal supplants that Acquisition Proposal because the Company determines such Acquisition Proposal is superior, then if such subsequent Acquisition Proposal is consummated) within nine months following the termination of the Merger Agreement, Stockholder shall pay to Parent within ten Business Days of the consummation of such Acquisition Proposal the Top-up Amount. The Top-up Amount shall be equal to 30.78% multiplied by the difference between (i) the aggregate fair value of the consideration that would have been received by the Stockholder pursuant to such Acquisition Proposal in respect of the Subject Securities that were sold in such bona fide sale to a third party and (ii) the aggregate fair value of the consideration received by such Stockholder in connection with such bona fide sale. For the avoidance of doubt, Parent and Merger Subsidiary acknowledge and agree that because of the undertaking by Stockholder in this Section 3(c) to disgorge a portion of the improved price of such Acquisition Proposal or Superior Proposal over the Offer Price (i) on and after the termination of the Merger Agreement (or the Expiration Date, if earlier) the Stockholder may take any actions necessary to consummate an Acquisition Proposal or Superior Proposal in lieu of the Offer, including, without limitation, withdrawing its shares from the Offer and voting in favor of such other Acquisition Proposal or Superior Proposal and (ii) prior to the termination of the Merger Agreement (or the Expiration Date, if earlier) the Stockholder may take any action except those prohibited by this Agreement, including the prohibitions referred to in Section 5 of this Agreement, and any of the Stockholder’s designees or affiliates who is a director or officer of the Company may expressly take such actions as are contemplated by the last two sentences of section 5 in connection with an Acquisition Proposal or Superior Proposal; and

(d) that it will not enter into an agreement, arrangement or understanding (whether written or oral) with WIC or Dimeling, Xxxxxxxxx and Park Reorganization Fund II, L.P. or their direct or indirect owners (and will not permit its direct or indirect owners to enter into any such agreements, arrangements or understandings) that affects or otherwise modifies the sharing agreement contemplated by Section 3(c) hereof or any other provisions of this Agreement in a manner adverse to Parent or Merger Subsidiary without the prior written consent of Parent.

Section 4. Voting of Subject Securities.

Stockholder Agreement. The Stockholder agrees that, during the period from the date of this Agreement until the Expiration Date:

(i) at any meeting of stockholders of the Company, however called, and at every adjournment or postponement thereof, the Stockholder shall (A) appear at the meeting, or otherwise cause all shares of Company Common Stock Owned by the Stockholder to be counted as present thereat for purposes of establishing a quorum, (B) vote or cause all shares of Company Common Stock Owned by the Stockholder to be voted in favor of the approval and adoption of the Merger Agreement and the approval of the Merger and (C) vote or cause all shares of Company Common Stock Owned by the Stockholder to be voted, against (1) any Acquisition Proposal (other than one by Parent or Merger Subsidiary) and (2) any amendment of the Company’s Certificate of Incorporation or Bylaws or other proposal, action or transaction involving the Company or any of its subsidiaries or any of its stockholders, which amendment or other proposal, action or transaction could reasonably be expected to prevent or materially impede or delay the consummation of the Offer, the Merger or the other transactions contemplated by the Merger Agreement or this Agreement or to deprive Parent or Merger Subsidiary of any material portion of the benefits anticipated by Parent or Merger Subsidiary to be received from the consummation of the Offer, the Merger or the other transactions contemplated by the Merger Agreement or this Agreement, or change in any manner the voting rights of Company Common Stock presented to the stockholders of the Company or in respect of which vote or consent of the stockholders is requested or sought, unless such transaction has been approved in advance by Parent or Merger Subsidiary; and

(ii) in the event written consents are solicited or otherwise sought from stockholders of the Company with respect to the approval or adoption of the Merger Agreement or with respect to the approval of the Merger, the Stockholder shall cause to be validly executed, with respect to all shares of Company Common Stock Owned by the Stockholder as of the record date fixed for the consent to the proposed action, a written consent or written consents to such proposed action.

Section 5. No Solicitation.

During the period from the date of this Stockholder Agreement through the Expiration Date, the Stockholder shall not, nor shall the Stockholder authorize or permit any representative

of the Stockholder to, directly or indirectly take any action prohibited by Section 6.03 of the Merger Agreement. Nothing contained in this Section 5 shall prevent any person affiliated with the Stockholder who is a director or officer of the Company or designated by the Stockholder as a director of officer of the Company, when acting in his capacity as a director or officer of the Company, from exercising his fiduciary duties as a director or officer of the Company including, without limitation, taking any actions permitted under Section 6.03 of the Merger Agreement. In addition, nothing in this Agreement shall (or require the Stockholder to attempt to) limit or restrict any designee or affiliate of the Stockholder who is a director or officer of the Company from acting in such capacity or voting in such person’s sole discretion on any matter (it being understood that this Agreement shall apply to the Stockholder solely in the Stockholder’s capacity as a stockholder of the Company). The Stockholder shall have no liability to Parent, Merger Subsidiary or any of their respective affiliates under this Agreement as a result of any action or inaction by any designee or affiliate of Stockholder who is a director or officer of the Company, in either case serving on the Company’s board of directors or as an officer of the Company and acting in such person’s capacity as a director, officer or fiduciary of the Company.
