     (1)    complete and execute, for and on behalf of the undersigned, in the
            undersigned's capacity as an officer, director and/or beneficial
            owner of more than ten percent (10%) of any equity securities of

            determine to be required or advisable pursuant to Section 16(a) and
            Section 13(d) of the Securities Exchange Act of 1934, as amended
            (the "Exchange Act") and the rules and regulations promulgated
            thereunder, or any successor laws and regulations, as a consequence
            of, or in respect of, the undersigned's ownership, acquisition or
            disposition of securities of the Company;

     (2)    do and perform any and all acts for and on behalf of the undersigned
            which may be necessary or desirable to complete and execute any such
            forms and schedules, including any amendments thereto, and timely
            file such forms and schedules, including any amendments thereto,
            with the United States Securities and Exchange Commission
            (the "SEC"), and any securities exchange or similar authority; and

     (3)    take any other action of any type whatsoever in connection with the
            foregoing which, in the opinion of such Attorney-in-Fact, may be of
            benefit to, in the best interest of, or legally required by, the
            undersigned, it being understood that the documents executed by such
            Attorney-in-Fact on behalf of the undersigned pursuant to this Power
            of Attorney shall be in such form and shall contain such information
            as such Attorney-in-Fact may approve in such Attorney-in-Fact's
            discretion.

        The undersigned hereby grants to each such Attorney-in-Fact full power
and authority to do and perform each and every act and thing whatsoever
requisite, necessary or proper to be done in the exercise of any of the rights
and powers herein granted, as fully to all intents and purposes as the
undersigned might or could do if personally present, with full power of
substitution and revocation, hereby ratifying and confirming all that each such
Attorney-in-Fact, or each such Attorney-in-Fact's substitute or substitutes,
shall lawfully do or cause to be done by virtue of this power of attorney and
the rights and powers herein granted.

        The undersigned acknowledges that each of the foregoing Attorneys-in-
Fact, in serving in such capacity at the request of the undersigned, are not
assuming, nor is the Company assuming, any of the undersigned's responsibilities
to comply with Section 16(a) and Section 13(d) of the Exchange Act.

        The undersigned agrees that each such Attorney-in-Fact may rely entirely
on information furnished orally or in writing by the undersigned to each such
Attorney-in-Fact. The undersigned also agrees to indemnify and hold harmless the
Company and each such Attorney-in-Fact against any losses, claims, damages or
liabilities (or actions in these respects) that arise out of or are based on any
untrue statement or omission of necessary facts in the information provided by
the undersigned to such Attorney-in-Fact for purposes of executing,
acknowledging, delivering and filing Forms 3, 4 and 5, and Schedules 13D and
13G, including any amendments thereto, and agrees to reimburse the
Company and each such Attorney-in-Fact for any legal or other expenses
reasonably incurred in connection with investigating or defending against any
such loss, claim, damage, liability or action.

        This Power of Attorney shall remain in full force and effect until the
undersigned is no longer required to file Forms 3, 4 and 5, or Schedules 13D and
13G, with respect to the undersigned's holdings of and transactions in
securities issued by the Company, unless earlier revoked by the undersigned
in a signed writing delivered to the foregoing Attorneys-in-Fact.
