The Agreement entitles certain holders of the Issuer's common stock (the "Holders") to register such shares under the Securities Act of 1933 (the "Securities Act"). The provisions of the Agreement provide that the Holders may demand that the Issuer file a registration statement under the Securities Act covering some or all of the Holder's registrable securities. The Agreement limits the number of demand registrations that the Issuer is required to make on behalf of the Holders. In an underwritten offering, the managing underwriter has the right, subject to specified conditions, to limit the number of registrable securities.

If the Issuer proposes to register any equity securities under the Securities Act, other than pursuant to demand registration rights noted above or specified excluded registrations, Holders may require the Issuer to include all or a portion of Holders' registrable securities in the registration and in any related underwriting. In an underwritten offering, the managing underwriter, if any, has the right, subject to specified conditions, to limit the number of registrable securities. In connection with the Issuer's IPO in November 2001, the Agreement was amended by Amendment No. 1, effective October 1, 2001, ("Amendment No. 1"). The Amendment No. 1 altered the expiration date for certain call rights granted under the Agreement.
