ITEM 4.  PURPOSE OF TRANSACTION.

         The Reporting Persons have acquired the Issuer's Common Stock for
investment purposes, and such purchases have been made in the Reporting
Persons' ordinary course of business. 

         In pursuing such investment purposes, the Reporting Persons may

Stock at times, and in such manner, as they deem advisable to benefit from
changes in market prices of such Common Stock, changes in the Issuer's
operations, business strategy or prospects, or from sale or merger of the

monitor the Issuer's operations, prospects, business development, management,
competitive and strategic matters, capital structure, and prevailing market
conditions, as well as alternative investment opportunities, liquidity
requirements of the Reporting Persons and other investment considerations.
Consistent with its investment research methods and evaluation criteria, the
Reporting Persons may discuss such matters with management or directors of
the Issuer, other shareholders, industry analysts, existing or potential
strategic partners or competitors, investment and financing professionals,
sources of credit and other investors.  Such factors and discussions may
materially affect, and result in, the Reporting Persons' modifying their
ownership of Common Stock, exchanging information with the Issuer pursuant to
appropriate confidentiality or similar agreements, proposing changes in the
Issuer's operations, governance or capitalization, or in proposing one or
more of the other actions described in subsections (a) through (j) of this
Item 4. 

         The Reporting Persons reserve the right to formulate other plans
and/or make other proposals, and take such actions with respect to their
investment in the Issuer, including any or all of the actions set forth in
paragraphs (a) through (j) of Item 4 of Schedule 13D, or acquire additional

may at any time reconsider and change their plans or proposals relating to
the foregoing.
