THE TOP-UP OPTION. The Company hereby grants to Purchaser an irrevocable option (the "TOP-UP OPTION") to purchase, subject to the terms hereof, that number of shares of common stock, $0.01 par value per share ("COMMON STOCK"), of the Company (the "TOP-UP OPTION SHARES") equal to the lowest number of shares of Common Stock that, when added to the number of shares of Common Stock owned by Purchaser at the time of such exercise, shall constitute one share more than 90% of the shares of Common Stock then outstanding (assuming the issuance of the Top-Up Option Shares) at a price per share equal to $5.25 (the "OPTION PRICE"); PROVIDED, HOWEVER, that the Top-Up Option shall not be exercisable unless immediately after such exercise Purchaser would own more than 90% of the shares of Common Stock then outstanding. 2. EXERCISE OF TOP-UP OPTION. (a) Purchaser may exercise the Top-Up Option, in whole but not in part, at any one time after the occurrence of a Top-Up Exercise Event (as defined below) and prior to the occurrence of a Top-Up Termination Event (as defined below). (b) A "TOP-UP EXERCISE EVENT" shall occur for purposes of this Agreement upon Purchaser's acceptance for payment pursuant to the Offer (as defined in the Merger Agreement) of shares of Common Stock constituting more than 85% but less than 90% of the shares of Common Stock then outstanding. (c) Each of the following shall be a "TOP-UP TERMINATION EVENT": (i) the Effective Time; (ii) the date which is ten (10) business days after the occurrence of the Top-Up Exercise Event (or such later date on which the closing of a purchase may be consummated, as set forth in Section 3(a) below); and (iii) the termination of the Merger Agreement. 3. CLOSING. (a) In the event Purchaser is entitled to and wishes to exercise the Top-Up Option, it shall send to the Company a written notice (the date of which being herein referred to as the "NOTICE DATE") specifying a place and date not earlier than three business days nor later than ten business days from the Notice Date for the closing of such purchase (the "CLOSING DATE"); PROVIDED, that if the closing of such purchase cannot be consummated by reason of any applicable judgment, injunction, decree, order, law or regulation, the period of time that would otherwise run pursuant to this sentence shall run instead from the date on which such restriction on consummation has expired or been terminated; and PROVIDED, further, that if prior notification to or approval of any regulatory or antitrust agency is required in connection with such purchase, Purchaser shall promptly file the required notice or application for approval, shall promptly notify the Company of such filing, and shall expeditiously process the same and the period of time that otherwise would run pursuant to this sentence shall run instead from the date on which any required notification periods have expired or been terminated or such approvals have been obtained and any requisite waiting period or periods shall have passed. Any exercise of the Top-Up Option shall be deemed to occur on the Notice Date relating thereto. (b) At the closing referred to in subsection (a) of this Section 3, Purchaser shall (i) pay to the Company the aggregate purchase price for the shares of Common Stock purchased pursuant to the exercise of the Top-Up Option in immediately available funds by wire transfer to a bank account designated by the Company (PROVIDED that failure or refusal of the Company to designate such a bank account shall not preclude Purchaser from exercising the Top-Up Option by delivery of a certified check or bank draft) and (ii) present and surrender this Agreement to the Company. (c) At such closing, simultaneously with the delivery of immediately available funds as provided in subsection (b) of this Section 3, the Company shall deliver to Purchaser a certificate or certificates representing the number of shares of Common Stock purchased by Purchaser. (d) Certificates for Common Stock delivered at a closing hereunder may be endorsed with a restrictive legend that shall read substantially as follows: "The transfer of the shares represented by this certificate is subject to resale restrictions arising under applicable securities laws (including the Securities Act of 1933, as amended)." It is understood and agreed that the reference to the resale restrictions arising under applicable securities laws, including the Securities Act of 1933, as amended (the "SECURITIES ACT"), in the 2 above legend shall be removed by delivery of substitute certificate(s) without such reference if Purchaser shall have delivered to the Company a copy of a letter from the staff of the Securities and Exchange Commission, or an opinion of counsel, in form and substance reasonably satisfactory to the Company, to the effect that such legend is not required for purposes of the Securities Act or other applicable securities laws. In addition, such certificates shall bear any other legend as may be required by law. (e) Upon the giving by Purchaser to the Company of the written notice of exercise of the Top-Up Option provided for under subsection (a) of this Section 3 and the tender of the applicable purchase price in immediately available funds, Purchaser shall be deemed to be the holder of record of the shares of Common Stock issuable upon such exercise, notwithstanding that the stock transfer books of the Company shall then be closed or that certificates representing such shares of Common Stock shall not then be actually delivered to Purchaser. The Company shall pay all expenses, and any and all United States federal, state and local taxes and other charges that may be payable in connection with the preparation, issue and delivery of stock certificates under this Section 3 in the name of Purchaser or its assignee, transferee or designee. 4.
