Item 4.        Purpose of Transaction.
               ----------------------

               JANA Partners LLC purchased the Shares based on its belief that
the Shares at current market prices are undervalued and represent an attractive
investment opportunity.  Depending upon overall market conditions, other
investment opportunities available to the Reporting Person, and the availability
of Shares of Common Stock at prices that would make the purchase of additional
Shares desirable, the Reporting Person may endeavor to increase their position
in the Issuer through, among other things, the purchase of Shares of Common
Stock on the open market or in private transactions or otherwise, on such terms
and at such times as the Reporting Persons may deem advisable.

               Neither the Reporting Person nor the Principals has any present
plan or proposal which would relate to or result in any of the matters set forth
in subparagraphs (a) - (j) of Item 4 of Schedule l3D except as set forth herein
or such as would occur upon completion of any of the actions discussed above.
The Reporting Person intends to review its investment in the Issuer on a
continuing basis and engage in discussions with management and the Board of
Directors of the Issuer concerning the business, operations and future plans of
the Issuer.  Depending on various factors including, without limitation, the
Issuer's financial position and investment strategy, the price levels of the
Common Stock, conditions in the securities market and general economic and
industry conditions, JANA Partners LLC may in the future take such actions with
respect to its investment in the Issuer as it deems appropriate including,
without limitation, communicating with other stockholders, seeking Board
representation, making proposals to the Issuer concerning the capitalization and
operations of the Issuer, purchasing additional Shares of Common Stock or
selling some or all of its Shares or changing its intention with respect to any
and all matters referred to in Item 4.

Item 5.        Interest in Securities of the Issuer.
               ------------------------------------

(a) The aggregate percentage of Shares of Common Stock reported owned
beneficially by the Reporting Person is based upon 9,024,000 Shares outstanding,
which is the total number of Shares of Common Stock outstanding as reported in
the Issuer's Quarterly Report on Form l0-Q for the quarter ended September 30,
2002.

As of the close of business on January 29, 2002, JANA Partners LLC beneficially
owned 494,500 Shares of Common Stock, constituting approximately 5.48% of the
Shares outstanding.

(b) The Reporting Person has sole voting and dispositive powers with respect to
the Shares reported herein, which powers are exercised by the Principals.  All
