The relative fault of the indemnifying party and of the indemnified party shall be determined by reference to, among other things, whether the untrue or alleged untrue statement of a material fact or the omission or alleged omission to state a material fact relates to information supplied by the indemnifying party or by the indemnified party and the parties' relative intent, knowledge, access to information and opportunity to correct or prevent such statement or omission. 9. UNDERWRITING AGREEMENT. (a) Notwithstanding the provisions of Sections 4, 5, 7 and 8, to the extent that the Company and at least the Majority of Registering Stockholders shall enter into an underwriting or similar agreement that contains provisions which conflict with any provision of any such Sections, the provisions contained in such agreement shall control with respect to such underwritten offering. (b) If any registration pursuant to Section 2 is requested to be an underwritten offering, the Company shall negotiate in good faith to enter into a reasonable and customary underwriting agreement with the underwriters thereof. The Company shall be entitled to receive indemnities from lead institutions, underwriters, selling brokers, dealer managers and similar securities industry professionals participating in the distribution, to the same extent as provided above with respect to information so furnished in writing by such Persons specifically for inclusion in any Prospectus or Registration Statement and to the extent customarily given their role in such distribution. (c) No Stockholder may participate in any registration hereunder that is underwritten unless such Stockholder agrees to (i) sell such Stockholder's Registrable Shares proposed to be included therein on the basis provided in any underwriting arrangements approved by the Company and the Majority of Registering Stockholders (which approval shall not be unreasonably withheld by such Stockholders) and (ii) as expeditiously as possible, notify the Company of the occurrence of any event concerning such Stockholder as a result of which the Prospectus relating to such registration contains an untrue statement of a material fact or omits to state a material fact required to be stated therein or necessary to 15 make the statements therein, in light of the circumstances under which they were made, not misleading. 10. NOMINEES FOR BENEFICIAL OWNERS. In the event that any Registrable Shares are held by a nominee for the beneficial owner thereof, the beneficial owner thereof may, at its election by written notice to the Company effective upon receipt by the Company, be treated as a Stockholder for purposes of any request or other action by any Stockholder pursuant to this Agreement or any determination of any number or percentage of shares of Registrable Shares held by any Stockholder contemplated by this Agreement. If the beneficial owner of any Registrable Shares so elects, the Company may require assurances reasonably satisfactory to it of such owner's beneficial ownership of such Registrable Shares. Prior to receipt by the Company of written notice contemplated hereby, any action taken by any nominee shall be binding upon any such beneficial owner. 11. INFORMATION BY HOLDER. The Stockholders shall furnish to the Company such written information regarding the Stockholders and the distribution proposed by the Stockholders as the Company may reasonably request in writing and as shall be reasonably required in connection with any registration, qualification or compliance referred to in this Agreement. 12.

The Company shall not, directly or indirectly, enter into any merger, consolidation, or reorganization in which the Company shall not be the surviving corporation unless the surviving corporation shall, prior to such merger, consolidation or reorganization, agree in writing to assume the obligations of the Company under this Agreement, and for that purpose references hereunder to "Registrable Shares" shall be deemed to include the shares of common stock, if any, that the Stockholders would be entitled to receive in exchange for Common Stock under any such merger, consolidation or reorganization; PROVIDED, HOWEVER, that, to the extent the Stockholders receive securities that are by their terms convertible into shares of common stock of the issuer thereof, then only such shares of common stock as are issued or 16 issuable upon conversion of said convertible securities shall be included within the definition of "Registrable Securities." 14. NEW CERTIFICATES. As expeditiously as possible after the effectiveness of any Registration Statement filed pursuant to this Agreement, the Company will deliver in exchange for any legended certificate evidencing Restricted Shares so registered, new stock certificates not bearing any restrictive legends, PROVIDED that in the event less than all of the Restricted Shares evidenced by such legended certificate are registered, the holder thereof agrees that a new certificate evidencing such unregistered shares will be issued bearing the appropriate restrictive legend. 15. SELECTION OF UNDERWRITER. The Company shall not, at any time after the date hereof, grant any registration rights that conflict with, or have any priority over, the registration rights granted hereby. The DLJ Investors will have the right to select the underwriters in any public offering resulting from an exercise by it of a Demand Registration. 16. TERMINATION.

Each Stockholder may assign its rights hereunder to any Permitted Transferee of Registrable Shares; PROVIDED, HOWEVER, that such Permitted Transferee shall, as a condition to the effectiveness of such assignment, be required to execute a counterpart to this Agreement agreeing to be treated as a Stockholder, whereupon such Permitted Transferee shall have the benefits of and shall be subject to the restrictions contained in this Agreement as if such Permitted Transferee was originally included in the definition of a Stockholder and had originally been a party hereto. (c) SEVERABILITY. It is the desire and intent of the parties hereto that the provisions of this Agreement be enforced to the fullest extent permissible under the laws and public policies applied in each jurisdiction in which enforcement is sought.

Notwithstanding the foregoing, if such provision could be more narrowly drawn so as not to be invalid, prohibited or unenforceable in such jurisdiction, it shall, as to such jurisdiction, be so narrowly drawn, without invalidating the remaining provisions of this Agreement or affecting the validity or enforceability of such provision in any other jurisdiction.
