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 further

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 Issuer.  To
evaluate such alternatives, the Reporting Persons will routinely 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 Item 4 of Schedule
13D.

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 Common Stock
or dispose of all the Common Stock beneficially owned by them, in the public
market or privately negotiated transactions.  The Reporting Persons may at
any time reconsider and change their plans or proposals relating to the
foregoing.
