Explanation of Responses: *On October 17, 1997, as an inducement to the
Reporting Person's entering into an Agreement and Plan of Merger (the
"Merger Agreement") with the Issuer, Mr. Ronald G. Canada, owner of
approximately 22.2% of the outstanding shares of Common Stock of the
Issuer, and the Reporting Person entered into a Stockholder Option
Agreement pursuant to which Mr. Canada granted the Reporting Person (i) an
option to purchase all of Mr. Canada's shares of Common Stock and (ii) a
proxy to vote all of Mr. Canada's shares of Common Stock in favor of the
proposed merger of the Issuer and a wholly-owned subsidiary of the
Reporting Person and the Merger Agreement and against certain transactions
that could impede consummation of the transactions contemplated by the
Merger Agreement. The option only becomes exercisable upon termination of
the Merger Agreement in certain circumstances and expires on the 31st
business day after any such termination.
