Item 4.           Purpose of the Transaction

         Little Wing, L.P. and Tradewinds (the "Reporting Entities") initially
acquired the shares of Common Stock in the Issuer for investment purposes only.
However, on July 24, 2002, the Reporting Entities decided to seek to influence
the make-up of the Issuer's Board of Directors and the fiscal policies of the
Issuer's management. The Reporting Entities delivered a letter to the Issuer's
Board of Directors requesting that the Board nominate Anthony Hitschler and
Gregg Summerville to fill two newly-created seats on the Issuer's Board of
Directors.

         The Reporting Entities believe that Messrs. Hitschler and Summerville
would improve the Issuer's financial discipline and expertise.

         Parker Quillen, President of Quilcap Corp. and Quilcap International,
also met in person on July 31, 2002 with the Issuer's newly appointed President
and Chief Executive Officer, Donald B. Hawthorne. The Reporting Entities are
optimistic that new management will similarly improve the Issuer's financial
discipline and expertise.

         Except as stated herein, the Reporting Entities have not decided on any
single or specific course or plan of action; however, the Reporting Entities
reserve the right to take such actions as they deem desirable to protect or
enhance the value of their investments in the Issuer.

Item 5.           Interest in Securities of the Issuer

                  (a) As of July 24, 2002, Little Wing, L.P. beneficially owned
1,545,492 shares of Common Stock constituting approximately 6.10% of the shares
outstanding based on information provided by the Issuer.

                  (b) As of July 24, 2002, Tradewinds beneficially owned 463,282
shares of Common Stock constituting approximately 1.83% of the shares
outstanding based on information provided by the Issuer.

         Little Wing, L.P. and Tradewinds engaged in no transactions in the
Issuer's Common Stock during the period commencing 60 days prior to the filing
date of this Report.
