               Each of the undersigned entities and individuals (collectively,
the "Reporting Persons") hereby designates the entity listed in Column II of
EXHIBIT A hereto, or such other person or entity as is designated in writing by
George A. Pavlov (any such entity is referred to as the "Designated Filer") as

amendments thereto) pursuant to Section 13(d) of the Securities Exchange Act of
1934 (the "Exchange Act") and of Forms 3, 4 and 5 (and any amendments thereto)
pursuant to Section 16(a) of the Exchange Act (collectively, the "Reports") with
respect to the securities of the entities listed in Column I of EXHIBIT A hereto
and with respect to the securities of any other entity whose securities are now,

               Each Reporting Person hereby further authorizes and designates
GEORGE A. PAVLOV (the "Authorized Signatory") to execute and file on behalf of

               The authority of the Designated Filer and the Authorized
