NOW, THEREFORE, in order to implement the foregoing and in consideration of the mutual agreements contained herein and the Original Agreement, and for other good and valuable consideration, the receipt and sufficiency of which is hereby acknowledged, the Company and the other parties hereto, intending to be legally bound hereby, agree as follows: 1. Section 4(c). Section 4(c) of the Original Agreement is hereby amended and restated in its entirety to read as follows: "(c) The Company may not include in any registration statement referred to in this Section 4 any shares of Common Stock to be sold for the account of any person not entitled as of June 17, 2003 to registration rights with respect to such shares except for the shares of Common Stock to be issued to persons purchasing such shares in connection with the Company's private placement of 1,000,000 shares of Common Stock as described in the Company's Private Placement Offering memorandum dated February 15, 1996, all of which persons have brokerage accounts with Gilder, Gagnon, Howe & Co at the closing of such transaction (collectively, the "Gilder Shares"). The Company may include in any registration requested pursuant to this Section 4 hereof any shares of Common Stock for sale for its own account or for the account of any other person entitled to "piggy-back" or "incidental rights" as of June 17, 2003, provided that such inclusion shall not affect the number of shares of Restricted Stock that can be sold in the related offering. In connection with an underwritten offering, if the managing underwriter advises the Company in writing that in its opinion the number of shares of Restricted Stock requested by the holders of Restricted Stock to be registered exceeds the number which can be sold in such offering, the Company shall include in such registration statement the number of shares of Restricted Stock that, in the opinion of the managing underwriter, can be 1 sold as follows: (i) first, the Restricted Stock requested to be registered, pro rata among the holders of Restricted Stock that have requested their Restricted Stock to be registered, (ii) second, Common Stock requested to be registered by holders of existing registration rights as of June 17, 2003 and (iv) third, any other Common Stock requested to be included in such registration. Except for registration statements on Form S-4, S-8 or any successor thereto, registration statements registering the Gilder Shares and/or securities to be issued by the Company to the seller or sellers in connection with an acquisition by the Company and registration statements required to be filed for holders of Common Stock who, as of June 17, 2003, are entitled to "demand" registration rights, the Company will not file with the Commission any other registration statement with respect to its Common Stock, whether for its own account or that of other stockholders, from the date of receipt of a notice from requesting holders pursuant to this Section 4 until the completion of the period of distribution of the registration contemplated thereby, as described in Section 7 herein." 2. Section 5. Section 5(a) of the Original Agreement is hereby amended by inserting the following after the last sentence: "Notwithstanding the provisions of this Section 5(a), if the registration was initiated by the Company at the request of a person or persons entitled to demand rights as of the date hereof exercising such demand rights, priority in underwriter cutbacks with respect to such registration shall be governed by the provisions of their particular agreement providing for such demand rights, provided that the holders of Restricted Stock that have requested inclusion of their Restricted Stock to be included therein shall have priority over any other persons holding securities requested to be included in such registration." 3. Sections 5 and 6. In Sections 5 and 6, all references to "June 30, 1998" are deleted and replaced with "June 17, 2003." 4. Effect of First Amendment. In all other respects, the Original Agreement, as amended hereby, remains in full force and effect as written. 5. Counterparts. This First Amendment may be executed in two or more counterparts, each of which shall be deemed an original, but all of which together shall constitute one and the same instrument. This document may also be delivered by facsimile transmission with the same force and effect as if originally executed copies of this document were delivered to all parties. 6. Governing Law. This First Amendment shall be governed by and construed in accordance with the laws of the State of Delaware.
