Item 5.  Past Contacts, Transactions, Negotiations and
         Agreements.

On January 5, 2001, Mr. Rogel telephoned Mr. Swindells to express Parent's
desire to meet and negotiate a business combination. Mr. Swindells stated that
the parties had nothing to discuss and that the Company was not for sale, and
declined Mr. Rogel's invitation to negotiate or otherwise discuss a business
combination transaction between Parent and the Company. Also on that day, Mr.
Rogel telephoned Mr. Smelick to express Parent's desire to meet and negotiate
a business combination transaction. Mr. Smelick did not return Mr. Rogel's
call. On January 5, 2001, Parent's financial advisor, Morgan Stanley,
telephoned Goldman Sachs, the Company's financial advisor, to discuss the
Offer and the Proposed Merger. Goldman Sachs declined to discuss the Offer and
the Proposed Merger in detail.
