On the basis of the representations and warranties contained in this Agreement, and subject to its terms and conditions, (i) each Seller agrees, severally and not jointly, to sell the Additional Shares set forth opposite such Seller's name in Schedule II hereto and (ii) the Underwriters shall have the right to purchase, severally and not jointly, up to 1,800,000 Additional Shares from the Sellers at the Purchase Price. Additional Shares may be purchased solely for the purpose of covering over-allotments made in connection with the offering of the Firm Shares. The Underwriters may exercise their right to purchase Additional Shares in whole or in part from time to time by giving written notice thereof to the Sellers within 30 days after the date of this Agreement. You shall give any such notice on behalf of the Underwriters and such notice shall specify the aggregate number of Additional Shares to be purchased pursuant to such exercise and the date for payment and delivery thereof, which date shall be a business day (i) no earlier than two business days after such notice has been given (and, in any event, no earlier than the Closing Date (as hereinafter defined)) and (ii) no later than ten business days after such notice has been given. If any Additional Shares are to be purchased, each Underwriter, severally and not jointly, agrees to purchase from the Sellers the number of Additional Shares (subject to such adjustments to eliminate fractional shares as you may determine) which bears the same proportion to the total number of Additional Shares to be purchased from the Sellers as the number of Firm Shares set forth opposite the name of such Underwriter in Schedule I bears to the total number of Firm Shares. Each of the Sellers agrees not to (i) offer, pledge, sell, contract to sell, sell any option or contract to purchase, purchase any option or contract to sell, grant any option, right or warrant to purchase, or otherwise transfer or dispose of, directly or indirectly, any shares of Common Stock or any securities convertible into or exercisable or exchangeable for Common Stock or (ii) enter into any swap or other arrangement that transfers all or a portion of the economic consequences associated with the ownership of any Common Stock (regardless of whether any of the transactions described in clause (i) or (ii) is to be settled by the delivery of Common Stock, or such other securities, in cash or otherwise), except to the Underwriters pursuant to this Agreement, for a period of 180 days after the date of the Closing Date (as defined below) without the prior written consent of Xxxxxxxxx, Xxxxxx & Xxxxxxxx Securities Corporation and the Company, which consent the Company may withhold in its sole discretion. Each Seller agrees that, for a period of 180 days after the date of the Prospectus without the prior written consent of Xxxxxxxxx, Lufkin & Xxxxxxxx Securities Corporation, it will not make any demand for, or exercise any right with respect to, the registration of any shares of Common Stock or any securities convertible into or exercisable or exchangeable for Common Stock. Each Seller shall, prior to or concurrently with the execution of this Agreement, deliver an agreement executed by such Seller to the effect that such person will not, during the period commencing on the date such person signs such agreement and ending 180 days after the date of the Prospectus, without the prior written consent of Xxxxxxxxx, Lufkin & Xxxxxxxx Corporation, (A) engage in any of the transactions described in the first sentence of this paragraph or (B) make any demand for, or exercise any right with respect to, the registration of any shares of Common Stock or any securities convertible into or exercisable or exchangeable for Common Stock; provided, that any such agreement shall not relieve any other obligation such Seller otherwise has to the Company.
