(b) If the Initiating Holders intend to distribute the Registrable Securities covered by their request by means of an underwriting, they shall so advise the Company as a part of their request made pursuant to this Section1.2 and the Company shall include such information in the written notice referred to in Section1.2(a). In such event the right of any Holder to include its Registrable Securities in such registration shall be conditioned upon such Holder's participation in such underwriting and the inclusion of such Holder's Registrable Securities in the underwriting to the extent provided herein. All Holders proposing to distribute their securities through such underwriting shall enter into an underwriting agreement in customary form with the underwriter or underwriters selected for such underwriting by the Company (which underwriter or underwriters shall be reasonably acceptable to a majority in interest of the Initiating Holders). Notwithstanding any other provision of this Section1.2, if the underwriter advises the Company that marketing factors require a limitation on the number of securities underwritten (including Registrable Securities), then the Company shall so advise all Holders of Registrable Securities that would otherwise be underwritten pursuant hereto, and the

number of shares that may be included in the underwriting shall be allocated to the Holders of such Registrable Securities pro rata based on the number of Registrable Securities held by all such Holders (including the Initiating Holders). In no event shall any Registrable Securities be excluded from such underwriting unless all other securities are first excluded. Any Registrable Securities excluded or withdrawn from such underwriting shall be withdrawn from the registration.

(c) Notwithstanding the foregoing, the Company shall not be required to effect a registration pursuant to this Section1.2:

(i) in any particular jurisdiction in which the Company would be required to execute a general consent to service of process in effecting such registration, unless the Company is already subject to service in such jurisdiction and except as may be required under the Act; or

(ii) after the Company has effected two registrations pursuant to this Section1.2, and such registrations have been declared or ordered effective; or

(iii) during the period starting with the date that is 60 days prior to the Company's good faith estimate of the date of the filing, and ending on a date 180 days following the effective date, of a Company-initiated registration subject to Section1.3 below or a request for registration under the Allocation Agreement,providedthat the Company is actively employing in good faith its reasonable best efforts to cause such registration statement to become effective;

(iv) if the Initiating Holders propose to dispose of Registrable Securities that may be registered on FormS-3 pursuant to Section1.4 hereof; or

(v) if the Company shall furnish to the Initiating Holders requesting a registration statement pursuant to this Section1.2 a certificate signed by the Company's Chief Executive Officer or Chairman of the Board stating that in the good faith judgment of the Board of Directors of the Company (the "Board"), it would be seriously detrimental to the Company and its stockholders for such registration statement to be effected at such time, in which event the Company shall have the right to defer such filing for a period of not more than 120 days after receipt of the request of the Initiating Holders,providedthat such right shall be exercised by the Company not more than once in any 12 month period, andprovided,further, that the Company shall not register any securities for the account of itself or any other stockholder during such 120 day period (other than a registration relating solely to the sale of securities of participants in a Company stock plan, a registration relating to a corporate reorganization or transaction under Rule145 of the Act, a registration on any form that does not include substantially the same information as would be required to be included in a registration statement covering the sale of the Registrable Securities, or a registration in which the only Common Stock being registered is Common Stock issuable upon conversion of debt securities that are also being registered).
