ARTICLE I

AGREEMENT TO CONVERT, TENDER AND VOTE

1.1 Agreement to Convert Company Preferred Stock. Each Stockholder agrees to convert each share of Company Preferred Stock set forth opposite such Stockholder’s name on Schedule A hereto into shares of Company Common Stock (any shares of Company Common Stock obtained by each such Stockholder upon such conversion, “Conversion Shares”) in accordance with the terms of Certificate of Designations of such Company Preferred Stock, dated as of December 18, 2003 (“Certificate of Designation”), but in any case after giving effect to the waiver of dividends contemplated by Section 1.2 if applicable, as provided in Section 1.3(b) unless converted prior to the effectiveness of the conversion contemplated thereby, such that in each case each Stockholder shall hold, beneficially and of record, as of the date of such conversion and thereafter until accepted for payment in the Offer a number of Conversion Shares no less than the number thereof set forth opposite such Stockholder’s name on Schedule A hereto. The date of the effectiveness of such conversion of all such shares of Company Preferred Stock into shares of Company Common Stock shall be referred to as the “Conversion Date.” The Company and each Stockholder that holds Company Preferred Stock hereby waive any and all provisions of the Certificate of Designation regarding the requirements and mechanics of such conversion.

1.2 Waiver of Dividends. Notwithstanding the obligation of conversion set forth in Section 1.1, if for any reason any Stockholder shall not have converted such Stockholder’s shares of Company Preferred Stock prior to November 14, 2011 (the “Dividend Accrual End Date”) or such conversion shall not have been effective by such date (including as contemplated by the procedures set forth in Section 1.3(b)), such Stockholder hereby waives (for itself and any successor in interest or transferee of any shares of the Company Preferred Stock) any right such Stockholder may have to any dividends (in any form whatsoever) which may accrue or have accrued, or may become payable, at any time after the Dividend Accrual End Date but on or prior to November 30, 2011 with respect to such shares of Company Preferred Stock except as set forth in the immediately following sentence. The waiver contemplated by this Section 1.2 shall be irrevocable; provided, however, that the waiver contemplated by this Section 1.2 shall automatically be revoked without any further or required action on the part of Parent, Merger Sub or such Stockholder following the termination of the Merger Agreement occurring prior to any acceptance for payment by Parent or Merger Sub of, or payment by Parent or Merger Sub for, shares of Company Common Stock tendered in the Offer. Without limitation to any right of Parent or Merger Sub hereunder, the Company and its successors and assigns are intended third party beneficiaries of this Section 1.2, and this Section 1.2 shall be enforceable by the Company and its successors and assigns.

1.3 Agreement to Tender.

(a) Each Stockholder agrees to validly tender or cause to be tendered in the Offer all of such Stockholder’s Subject Shares (which, for the avoidance of doubt, shall include all Conversion Shares) pursuant to and in accordance with the terms of the Offer, free and clear of all Liens (other than Permitted Liens). In furtherance of the foregoing, as promptly as practicable after, but in no event later than (10) Business Days after, the commencement of the Offer (other than with respect to the Conversion Shares, for which the conversion and tender thereof shall be effected as provided in Section 1.3(b) unless converted prior to the effectiveness of the conversion contemplated thereby), each Stockholder shall: (i) deliver or cause to be delivered to the depositary designated in the Offer Documents and pursuant to the terms of the Offer (A) a letter of transmittal with respect to such Stockholder’s Subject Shares complying with the terms of the Offer, (B) certificates representing such Subject Shares or an “agent’s message” (or such other evidence, if any, of transfer as the depositary

2

designated in the Offer Documents or Paying Agent may reasonably request) in the case of a book-entry share of any uncertificated Subject Shares and (C) any and all other documents or instruments required to be delivered by other Company Stockholders pursuant to the terms of the Offer, and (ii) instruct and cause any other Person who is the record holder of any such Subject Shares (including the Stockholder’s broker, if applicable) to validly tender such Subject Shares pursuant to and in accordance with the terms and conditions of the Offer and the Offer Documents. Each Stockholder agrees that, once such Stockholder’s Subject Shares are tendered, such Stockholder will not (and will cause anyone acting on its behalf not to) withdraw any of such Subject Shares from the Offer unless and until (A) the Offer shall have been terminated in accordance with the terms of the Merger Agreement or (B) this Agreement shall have been terminated in accordance with its terms.

(b) Unless each Stockholder has converted each share of Company Preferred Stock set forth opposite such Stockholder’s name on Schedule A hereto into the applicable Conversion Shares by the date (10) Business Days after the commencement of the Offer, each Stockholder agrees to validly tender or cause to be tendered in the Offer all of such Stockholder’s Conversion Shares pursuant to and in accordance with the terms of the Offer, free and clear of all Liens (other than Permitted Liens) in the manner contemplated by this Section 1.3(b). As promptly as practicable after, but in no event later than (10) Business Days after, the commencement of the Offer, each Stockholder shall: (i) deliver or cause to be delivered to the depositary designated in the Offer Documents and pursuant to the terms of the Offer (A) certificates representing the shares of Company Preferred Stock from which the Conversion Shares are to be issued upon conversion thereof (or such other evidence, if any, of transfer as the depositary designated in the Offer Documents or Paying Agent may reasonably request), (B) a notice of conversion of such shares of Company Preferred Stock into the Conversion Shares (in any case after giving effect to the waiver of dividends contemplated by Section 1.2 if applicable), which shall be effected immediately prior to the Acceptance Time but prior to the expiration of the Offer, which shares of Conversion Shares shall be tendered as contemplated by the letter of transmittal prior to the expiration of the Offer contemplated by clause (C) hereof, which notice shall be irrevocable except as contemplated by the last sentence of this Section 1.3(b), (C) a letter of transmittal with respect to such Stockholder’s Conversion Shares complying with the terms of the Offer and this Section 1.3(b), which shall be deemed effective immediately following the issuance of the Conversion Shares as provided in clause (B) hereof and prior to the expiration of the Offer, and (D) any and all other documents or instruments required to be delivered by other Company Stockholders pursuant to the terms of the Offer, and (ii) instruct and cause any other Person who is the record holder of any such shares of Company Preferred Stock or Conversion Shares (including the Stockholder’s broker, if applicable) to validly tender such Conversion Shares pursuant to and in accordance with the terms and conditions of the Offer and the Offer Documents and this Section 1.3(b). Any instruments to be delivered by any Stockholder pursuant this Section 1.3(b) shall be in a form that is reasonably acceptable to Parent, approval of which shall not be unreasonably delayed, conditioned or withheld, and shall be delivered by such Stockholder only after providing Parent and its counsel a reasonable opportunity to review and comment on any such instruments. Each Stockholder shall provide copies of all instruments to be delivered by such Stockholder pursuant to this Section 1.3(b) to the Company and shall execute any other documents as are necessary or appropriate (including any instrument requested by the Company’s transfer agent) to effectuate the conversion of the Company Preferred Stock into the Conversion Shares and the transfer thereof as contemplated hereby. The Stockholder hereby directs the Company, on his behalf, to take all action necessary to effect the issuance and transfer of the Conversion Shares issued upon the conversion of shares of Company Preferred Shares contemplated by clause (B) above. The Company covenants to cause its transfer agent to record such

3

conversion and transfer to Merger Sub in the Company’s stock book on the terms set forth therein and to take all other reasonable action as is required to effect the conversion and tender contemplated hereby. Each Stockholder agrees that, once such Stockholder’s Conversion Shares are tendered (including upon delivery of the shares of Company Preferred Stock), such Stockholder will not (and will cause anyone acting on its behalf not to) withdraw any of such Conversion Shares from the Offer unless and until (A) the Offer shall have been terminated in accordance with the terms of the Merger Agreement or (B) this Agreement shall have been terminated in accordance with its terms.

(c) If the Offer is terminated or withdrawn by Parent or Merger Sub, or the Merger Agreement is terminated prior to the purchase of the Subject Shares in the Offer, Parent and Merger Sub shall promptly return, and shall cause any depositary acting on behalf of Parent or Merger Sub to return, all tendered Subject Shares to the registered holders of the Subject Shares (and in connection with the foregoing, Parent and Merger Sub will direct the depositary to so return such tendered Subject Shares within three Business Days of any such termination or withdrawal).

4.2. No Transfer; No Inconsistent Arrangements.

Such Stockholder agrees that it shall not, and shall cause each of its Affiliates not to, become a member of a “group” (as defined under Section 13(d) of the Exchange Act) with respect to any Equity Interests in the Company for the purpose of opposing or competing with or taking any actions inconsistent with the transactions contemplated by the Merger Agreement.

In the event that any Stockholder shall become the beneficial owner of any other securities entitling the holder thereof to vote or give consent with respect to the matters set forth in Section 4.1, then the terms of Section 4.1 shall apply to such other securities as though they were Subject Shares hereunder.

9

(a) In the event that (i) the Merger Agreement shall have been terminated pursuant to Sections 9.1(b)(i), 9.1(b)(ii)(B), 9.1(d)(i) (other than as a result of a breach arising out of facts or circumstances in existence on or prior to the date of the Merger Agreement), 9.1(c)(ii), 9.1(d)(ii)(A) or 9.1(d)(ii)(B) thereof and (ii) at any time prior to the expiration of the twelfth (12th) month after any such termination of the Merger Agreement, the Company consummates any transaction contemplated by an Acquisition Proposal (solely for this use, all references in the definition of Acquisition Proposal to “twenty percent (20%)” shall be replaced with “thirty-five percent (35%)”) or enters into any Alternative Acquisition Agreement or any letter of intent, agreement in principle or other similar agreement related to an Acquisition Proposal, or the Company Board shall have recommended an Acquisition Proposal (solely for this use, all references in the definition of Acquisition Proposal to “twenty percent (20%)” shall be replaced with “thirty-five percent (35%)”) to the Company Stockholders (any such transaction contemplated by such an Acquisition Proposal, an “Alternative Transaction”), each Stockholder shall pay to Parent the Applicable Profit (as defined and determined as set forth in Section 4.7(b)) of such Stockholder. Payment of the foregoing amount by each Stockholder shall be made to Parent within one (1) Business Day following the receipt by Stockholder of the proceeds from such Transfer of Subject Shares. Each Stockholder shall elect to participate in any such Alternative Transaction to the maximum extent permissible by the terms thereof. No Stockholder shall agree to accept consideration in such Alternative Transaction different than the consideration received by all other others of Company Common Stock.

(b) For purposes of this Section 4.7, the “Applicable Profit” of a Stockholder with respect to any Transfer in connection with the consummation of an Alternative Transaction contemplated by Section 4.7(a) shall mean:

(i) if the Per Share Alternative Acquisition Price (as defined below) is greater than the Offer Price and less than or equal to the product of (x) the Offer Price multiplied by (y) 1.13, 90% of the “First Tier Profit,” with “First Tier Profit” defined as the product of (I) the aggregate amount of all Subject Shares of such Stockholder transferred in the Alternative Transaction (on an as-exercised or as-converted basis, as applicable, with respect to any warrants, options, conversion rights or similar rights constituting Subject Shares), multiplied by (II) the excess amount by which the Per Share Alternative Acquisition Price exceeds the Offer Price;

(ii) if the Per Share Alternative Acquisition Price is greater than the product of (x) the Offer Price multiplied by (y) 1.13 and less than or equal to the product of (x) the Offer Price multiplied by (y) 1.26, the sum of (A) 90% of the First Tier Profit (assuming for purposes of calculating such First Tier Profit that the Per Share Alternative Acquisition Price equals the product of (x) the Offer Price multiplied by (y) 1.13) plus (B) 60% of the product of (I) the aggregate amount of all Subject Shares of such Stockholder transferred in the Alternative Transaction (on an as-exercised or as-converted basis, as applicable, with respect to any warrants, options, conversion rights or similar rights constituting Subject Shares), multiplied by (II) the excess amount by which the Per Share Alternative Acquisition Price exceeds the product of (x) the Offer Price multiplied by (y) 1.13;

(iii) if the Per Share Alternative Acquisition Price is greater than the product of (x) the Offer Price multiplied by (y) 1.26 and less than or equal to the product of (x) the Offer Price multiplied by (y) 1.39, the sum of (A) the amount set forth in Section 4.7(b)(ii) (assuming for purposes of calculating such amount that the Per Share Alternative Acquisition Price equals the product of (x) the Offer Price multiplied by (y) 1.26) plus (B) 35% of the product of (I) the aggregate amount of all

10

Subject Shares of such Stockholder transferred in the Alternative Transaction (on an as-exercised or as-converted basis, as applicable, with respect to any warrants, options, conversion rights or similar rights constituting Subject Shares), multiplied by (II) the excess amount by which the Per Share Alternative Acquisition Price exceeds the product of (x) the Offer Price multiplied by (y) 1.26;

(iv) if the Per Share Alternative Acquisition Price is greater than the product of (x) the Offer Price multiplied by (y) 1.39, the amount set forth in Section 4.7(b)(iii) (assuming for purposes of calculating such amount that the Per Share Alternative Acquisition Price equals the product of (x) the Offer Price multiplied by (y) 1.39).

For purposes of this Section 4.7, the “Per Share Alternative Acquisition Price” shall equal the aggregate amount of all consideration received by any Stockholder in any Alternative Transaction to which Section 4.7(a) shall be applicable (including any extraordinary distributions directly or indirectly made in connection with the consummation of the transactions contemplated by such Alternative Transaction) with respect to its Subject Shares, but in each case less the Per Share Alternative Acquisition Expense Amount (as defined below), valuing any non-cash consideration (including any residual interest in the Company) at its fair market value on the date of such Alternative Transaction, and in the case of any Equity Interests other than Company Common Stock, determined on an as-exercised or as-converted basis, as applicable, with respect to any warrants, options, conversion rights or similar rights constituting shares of Company Common Stock and less any exercise price or similar expense with respect to any warrants, options, conversion rights or similar rights constituting Equity Interests actually paid in connection with such Alternative Transaction. The “Per Share Alternative Acquisition Expense Amount” shall mean the amount equal to (x) the aggregate amount of all reasonable fees and expenses incurred by the Stockholder in connection with the Alternative Transaction to which this Section 4.7 shall be applicable (including, without limitation, all reasonable fees and expenses of the Stockholder incurred in connection with negotiating, entering into an agreement with respect to and consummating the Alternative Transaction) divided by (y) the aggregate amount of all Subject Shares of such Stockholder transferred in the Alternative Transaction (on an as-exercised or as-converted basis, as applicable, with respect to any warrants, options, conversion rights or similar rights constituting Subject Shares).

(c) For purposes of determining the fair market value of any non-cash consideration received in an Alternative Transaction to which this Section 4.7 shall be applicable:

(i) the fair market value of securities listed on a national securities exchange (“Traded Securities”) shall be equal to the volume weighted average closing price per share of such security as reported on the composite trading system of such exchange for the thirty (30) trading days ending on the trading day immediately prior to the date of the value determination (the “Valuation Period”); and

(ii) the fair market value of consideration which is other than cash or Traded Securities shall be (x) the fair market value thereof as determined in good faith by the Stockholders and Parent set forth in writing or (y) if the Stockholders and Parent are unable to agree on the fair market value of such consideration within five (5) Business Days following the occurrence of the event giving rise to the payment of any Applicable Profit, the fair market value as determined by a nationally recognized independent investment banking firm mutually agreed upon by Parent and the Stockholders (such agreement not to be unreasonably withheld and which firm shall not have a business relationship with

11

Parent or the Company or the Stockholder), within ten (10) Business Days following the occurrence of the event giving rise to the payment of any Applicable Profit (which firm shall determine the fair market value thereof on the date of the occurrence of the event giving rise to the payment of any Applicable Profit on third party arm’s length terms and without applying any marketability, minority position or other similar discount); provided, further, that the fees and expenses of such investment firm shall be borne equally by Parent, on the one hand and the Stockholders, collectively, on the other hand. The determination of the investment banking firm finally selected shall be binding upon the parties.

(d) Any payment of Applicable Profit pursuant to this Section 4.7 shall be paid in the same proportion of cash and non-cash consideration as the aggregate consideration received by such Stockholder in connection with the consummation of the transactions contemplated by Section 4.7(a).

(e) Each Stockholder shall not engage in any transaction with respect to the Subject Shares with the primary purpose of depriving Parent of the intended benefits of this Agreement.

(f) Neither Parent nor any Stockholder shall, or shall permit any of their respective Affiliates to, engage in any Prohibited Activity with respect to any Traded Securities during an applicable Valuation Period. “Prohibited Activity” means (A) any acquisition or disposition, in open market transactions, private transactions or otherwise, during the Valuation Period of any of the subject Traded Securities or any securities convertible into or exchangeable for or derivative of the subject Traded Securities or (B) any other action taken intentionally for the purpose of manipulating the price of the subject Traded Securities during the Valuation Period.

4.8. Legending of Shares. If so requested by Parent, Stockholder agrees that the Subject Shares shall bear a legend stating that they are subject to this Agreement.

4.9. Director Resignations. Promptly following the Acceptance Time, upon the written request from Parent, each Stockholder shall (a) take all action to cause any director serving on the board of directors of the Company who is also a Representative of such Stockholder to resign from such directorship if necessary or helpful to allow Parent to realize the full benefits contemplated by Section 2.4 of the Merger Agreement and (b) waive any right it or any of its Affiliates may have to designate, nominate or appoint any member of the board of directors of the Company.
