Agreement, each Stockholder shall cease immediately and cause to be terminated

heretofore with respect to any Acquisition Proposal and promptly request that
all confidential information with respect thereto furnished by such Stockholder
be returned. Each Stockholder shall, as promptly as practicable (and in no event
later than 24 hours after receipt thereof), advise Parent of any inquiry
received by it relating to any potential Acquisition Proposal and of the

transactions contemplated by this Agreement and the Merger Agreement, including
promptly making all regulatory filings and applications, and to obtain all
licenses, permits, consents, approvals, authorizations, qualification and orders

Merger or request appraisal of its respective Subject Shares pursuant to Section
262 of the DGCL or any other similar provisions of law in connection with the
Merger.

            Section 5.5 Lock-Up Agreement. Each Stockholder agrees that, in
connection with any public offering of Parent Common Stock or securities
convertible into Parent Common Stock conducted by Parent after the Effective
Time (a "Financing") and at the request of any managing underwriter of such
Financing, it will enter into a customary "lock-up" agreement pursuant to which
it will agree beginning on the date of the final prospectus delivered in

Common Stock (or any securities convertible into, exercisable for or
exchangeable for Parent Common Stock) or interest therein of Parent or any
