         purchase, purchase any option or contract to sell, grant any option,
         right or warrant to purchase or otherwise transfer or dispose of,

         derivative transactions), or announce the offering of, any Shares
         (including any that it may gain rights or ownership to after the date
         of this Agreement), or any securities issuable upon any conversion,
         exchange, reset or otherwise with respect to, such Shares.

2.       Each Holder hereby represents and warrants that other than what is
         disclosed in the Purchase Agreement, the accompanying schedules and
         exhibits, and the Company's SEC filings, neither they nor any other
         affiliates beneficially own or otherwise have the right to receive any
         Shares, or any economic interest therein or derivative therefrom, other
         than those Shares specified on its signature page to this Agreement.



3.       The Holders and the Company each acknowledge and agree that this
         Agreement is entered into for the benefit of and is enforceable by the
         Investors and their successors and assigns. Accordingly, the parties
         understand and agree that any Investor shall have the right to seek any
         one or more remedies for any act in contravention of this Agreement,
         including obtaining injunctive relief and monetary damages against any
         one or more of the parties hereto.

4.       Other than the consideration specifically referenced herein, the
         parties hereto agree that no fee, payment or additional consideration
         in any form has or will be paid to any Holder in connection with, or as
         an inducement to enter into, this Agreement.

5.       This Agreement will terminate as of the first to occur of (i) notice
         from the Company and the Investors that the transactions contemplated
         by the Purchase Agreement shall have been terminated in accordance with
         their terms, or (ii) 60 days after the Effective Date of the
         Registration Statement.

6.       This Agreement may not be amended, waived, restated, modified or
         assigned in any manner except by a written agreement executed by each
         of the parties hereto and then if and only if consented to in writing
         by the Investors.

7.       Each party hereto shall notify the other and the Investors of any
         breach or purported breach of this Agreement in writing.

8.       This Agreement may be executed in facsimile and in any number of
         counterparts, each of which when so executed and delivered shall be
         deemed an original, but all of which shall together constitute one and
         the same agreement.

9.       If any provision of this Agreement is held to be invalid or
         unenforceable for any reason, such provision will be conformed to
         prevailing law rather than voided, if possible, in order to achieve the
         intent of the parties and, in any event, the remaining provisions of
         this Agreement shall remain in full force and effect and shall be
         binding upon the parties hereto.

10.      The terms and provisions of this Agreement shall be construed in
         accordance with the laws of the State of New York, without regards to
         principles of conflicts of law, and the federal laws of the United
         States of America applicable therein.
