          Reference is hereby made to Items 5-9 and 11 of page two (2) of
this Schedule 13G, which Items are incorporated by reference herein.

          Under the definition of "beneficial ownership" in Rule 13d-3 under
the Securities Exchange Act of 1934, it is also possible that the individual
directors, executive officers, and/or shareholders of Wentworth might be
deemed the "beneficial owners" of some or all of the securities to which this
Schedule relates in that they might be deemed to share the power to direct
the voting or disposition of such securities.  Neither the filing of this
Schedule nor any of its contents shall be deemed to constitute an admission
that any of such individuals is, for any purpose, the beneficial owner of any
of the securities to which this Schedule relates, and such beneficial
ownership is expressly disclaimed.

Item 5.   Ownership of Five Percent or Less of a Class.

          Not applicable.

Item 6.   Ownership of More Than Five Percent on Behalf of Another Person.
          
          Wentworth is deemed to be the beneficial owner of the number of
securities reflected in Items 5-9 and 11 of page two (2) of this Schedule 13G
pursuant to separate arrangements whereby Wentworth acts as investment
adviser to certain persons.  Each person for whom the reporting person acts
as investment adviser has the right to receive or the power to direct the
receipt of dividends from, or the proceeds from the sale of, the Common Stock
purchased or held pursuant to such arrangements.
