FEDERAL INCOME TAX CONSEQUENCES

IN THE CASE OF RESTRICTED STOCK, AN EMPLOYEE WILL GENERALLY NOT BE DEEMED TO
HAVE REALIZED TAXABLE INCOME UPON RECEIPT OF SUCH SHARES. AN EMPLOYEE WILL
REALIZE ORDINARY INCOME ON THE DATE ON WHICH THE RESTRICTED STOCK IS NO LONGER
SUBJECT TO FORFEITURE, IN AN AMOUNT EQUAL TO THE FAIR MARKET VALUE OF THE SHARES

TIME THEY ARE ISSUED. SUCH AN ELECTION MUST BE MADE WITHIN 30 DAYS AFTER THE
DATE OF THE ISSUANCE OF RESTRICTED STOCK AND MAY NOT BE REVOKED BY THE EMPLOYEE
EXCEPT WITH THE CONSENT OF THE INTERNAL REVENUE SERVICE. IN THE EVENT THAT AN
ELECTION IS MADE AND THE RESTRICTED STOCK IS SUBSEQUENTLY FORFEITED, AN EMPLOYEE
WILL NOT BE ENTITLED TO A DEDUCTION WITH RESPECT TO THE FORFEITURE.

THE CORPORATION WILL BE ENTITLED TO A DEDUCTION FOR THE AMOUNT INCLUDED IN THE
ORDINARY INCOME OF THE EMPLOYEE IN THE YEAR IN WHICH SUCH INCLUSION OCCURS.
