SECTION 1 - REGISTRANT'S BUSINESS AND OPERATIONS

ITEM 1.01.  ENTRY INTO A MATERIAL DEFINITIVE AGREEMENT

On February 3, 2005, based in part on the Company's preliminary 2004 financial
results and a review of the total compensation of CEO's and other Executive
Officers of comparable companies prepared by independent professional
compensation consultants ("the Study"), the Board of Directors increased the
annual base salary component of its employment agreement with James E. Declusin,
President and Chief Executive Officer, to $560,000, and approved one-time
discretionary cash bonus awards for certain Executive Officers, including Mr.
Declusin, in addition to the amounts payable under the 2004 Annual Incentive
Plan. The total additional cash bonus amount for CEO and Executive Officers was
approximately $398,000. The new CEO base salary and the one-time discretionary
cash bonuses were in line with the recommendations of the Study.

The other terms of the Company's employment agreement with Mr. Declusin, which
expires on December 31, 2005, remained unchanged.

This summary is not intended to be a complete description of all of the terms of
the discretionary cash bonus awards. For further information, review the
Corporation's Form 10-K for the year ended December 31, 2004 and related proxy
statement.
