from  time to  time,  either  in the  open  market  or in  privately  negotiated

without  limitation,  the  price per share of the  Common  Stock,  the terms and
conditions  related to the purchase and sale, the prospects and profitability of
the Company, other business and investment  alternatives of the Reporting Person
and general  economic and market  conditions.  At any time, the Reporting Person
may  determine  to  dispose  of  some or all of his  holdings  of  Common  Stock
depending on those and other considerations.

         Other than as described in this Schedule 13D, the Reporting  Person has
no plans or  proposals  which would result in the  acquisition  by any person of

reorganization or liquidation, involving the Company or any of its subsidiaries;
a sale or transfer  of a material  amount of assets of the Company or any of its
subsidiaries;  any change in the present board of directors or management of the
Company,  including  any  place or  proposals  to change  the  number or term of
directors or to fill any existing vacancies on the Company's Board; any material
change in the present  capitalization  or dividend  policy of the  Company;  any
other  material  change in the Company's  business or corporate  structure;  any
changes in Company's  charter,  bylaws or instruments  corresponding  thereto or
other actions which may impede the  acquisition of control of the Company by any

national  securities  exchange or to cease to be  authorized  to be quoted in an
inter-dealer quotation system of a registered national securities association; a
class of equity  securities of the Company becoming  eligible for termination of
registration  pursuant to section  12(g)(4) of the Act; or any action similar to
any of those enumerated above.
