            provision of this Agreement. The Investor agrees to execute and
            deliver any additional documents necessary or desirable, in the
            reasonable opinion of the Company, to carry out the intent of this
            Agreement.

      1.3   Successors. The provisions of this Agreement shall be binding upon
            the successors in interest to, and to any transferee of, any of the
            shares of Preferred Stock. The Investor shall not sell, exchange,
            transfer, pledge or otherwise dispose, and the Company shall not
            permit the sale, exchange, transfer, pledge or other disposition, of
            any of the shares of Preferred Stock unless and until the person to
            whom such security is to be transferred shall have executed a
            written agreement, substantially in the form of this Agreement,
            pursuant to which such person becomes a party to this Agreement and
            agrees to be bound by all the provisions hereof as if such person
            were the Investor. Until the delivery by a transferee of such a
            written agreement, the Company shall not be obligated to transfer
            such shares of Preferred Stock on its books and records, nor shall
            the Company be required to issue any new certificates representing
            such shares.

      1.4   Other Rights. Except as provided by this Agreement or any other
            agreement entered into in connection with the Financing, the
            Investor



            shall exercise the full rights of a holder of capital stock of the
            Company with respect to the Investor Shares.

2.    TERMINATION. This Agreement shall continue in full force and effect from
the date hereof through earlier of: (a) ten years from the date hereof and (b)
the date on which the Investor no longer holds any shares of Preferred Stock.

3.    MISCELLANEOUS.

      3.1   Specific Performance. The parties hereto hereby declare that it is
            impossible to measure in money the damages which will accrue to a
            party hereto or to their heirs, personal representatives, or assigns
            by reason of a failure to perform any of the obligations under this
            Agreement and agree that the terms of this Agreement shall be
            specifically enforceable. If any party hereto or his heirs, personal
            representatives, or assigns institutes any action or proceeding to
            specifically enforce the provisions hereof, any person against whom
            such action or proceeding is brought hereby waives the claim or
            defense therein that such party or such personal representative has
            an adequate remedy at law, and such person shall not offer in any
            such action or proceeding the claim or defense that such remedy at
            law exists.

      3.2   Governing Law. This Agreement, and the rights of the parties hereto,
            shall be governed by and construed in accordance with the laws of
            the State of Delaware as such laws apply to agreements among
            Delaware residents made and to be performed entirely within the
            State of Delaware.

      3.3   Amendment or Waiver. This Agreement may be amended (or provisions of
            this Agreement waived) only by an instrument in writing signed by
            the Company and the Investor. Any amendment or waiver so effected
            shall be binding upon the Company, each of the parties hereto and
            any assignee of any such party.

      3.4   Severability. In the event one or more of the provisions of this
            Agreement should, for any reason, be held to be invalid, illegal or
            unenforceable in any respect, such invalidity, illegality or
            unenforceability shall not affect any other provisions of this
            Agreement, and this Agreement shall be construed as if such invalid,
            illegal or unenforceable provision had never been contained herein.

      3.5   Successors. This Agreement shall inure to the benefit of and be
            binding upon the parties hereto and their respective heirs,
            successors, assigns, administrators, executors and other legal
            representatives.

      3.6   Additional Shares. In the event that subsequent to the date of this
            Agreement any shares or other securities are issued on, or in
            exchange for, any of the Investor Shares by reason of any stock
            dividend, stock



            split, combination of shares, reclassification or the like, such
            shares or securities shall be deemed to be included in the
            definition of Investor Shares for purposes of this Agreement.

      3.7   Counterparts. This Agreement may be executed in one or more
            counterparts, each of which will be deemed an original but all of
            which together shall constitute one and the same agreement.

      3.8   Waiver. No waivers of any breach of this Agreement extended by any
            party hereto to any other party shall be construed as a waiver of
            any rights or remedies of any other party hereto or with respect to
            any subsequent breach.

      3.9   Attorney's Fees. In the event that any suit or action is instituted
            to enforce any provision in this Agreement, the prevailing party in
            such dispute shall be entitled to recover from the losing party all
            fees, costs and expenses of enforcing any right of such prevailing
            party under or with respect to this Agreement, including without
            limitation, such reasonable fees and expenses of attorneys and
            accountants, which shall include, without limitation, all fees,
            costs and expenses of appeals.

      3.10  Notices. Any notices required in connection with this Agreement
            shall be in writing and shall be deemed effectively given: (a) upon
            personal delivery to the party to be notified, (b) when sent by
            confirmed electronic mail or facsimile if sent during normal
            business hours of the recipient; if not, then on the next business
            day, (c) five (5) days after having been sent by registered or

            one (1) day after deposit with a nationally recognized overnight
            courier, specifying next day delivery, with written notification of
            receipt. All notices shall be addressed to the holder appearing on
            the books of the Company or at such address as such party may
            designate by ten (10) days advance written notice to the other
            parties hereto.

      3.11  Entire Agreement. This Agreement, along with the Subscription
            Agreement and each of the Annexes thereto, constitute the full and
            entire understanding and agreement between the parties with regard
            to the subjects hereof and thereof and no party shall be liable or
            bound to any other in any manner by any representations, warranties,
            covenants and agreements except as specifically set forth herein and
            therein.
