or such other address as may be provided to Grantee by written notice. Any
notice to Grantee under this Award shall be made to Grantee at the address
listed in the Company's personnel files. All notices under this Award shall be
deemed to have been given when hand-delivered, telecopied or delivered by first
class mail, postage prepaid, and shall be irrevocable once given.

                  8. Securities Laws. The Committee may from time to time impose
any conditions on the Restricted Shares as it deems necessary or advisable to
ensure that the Plan satisfies the conditions of Rule 16b-3, and that Shares are
issued and resold in compliance with the Securities Act of 1933, as amended.

                  9. Delivery of Shares. Upon a Vesting Date, the Company shall
notify Grantee (or Grantee's legal representatives, estate or heirs, in the
event of Grantee's death before a Vesting Date) that the restrictions on the
Restricted Shares have lapsed. Within ten (10) business days of a Vesting Date,
the Company shall, without payment from Grantee for the Restricted Shares,
deliver to Grantee a certificate for the Restricted Shares without any legend or
restrictions, except for such restrictions as may be imposed by the Committee,
in its sole judgment, under Paragraph 8, provided that no certificates for
Shares will be delivered to Grantee until appropriate arrangements have been
made with Employer for the withholding of any taxes which may be due with
respect to such Shares. The Company is authorized to withhold from any cash
remuneration then or thereafter payable to Grantee an amount sufficient to cover
required tax withholdings and is further authorized to cancel a number of Shares
for which the restrictions have lapsed having an aggregate Fair Market Value
equal to the required tax withholdings. The Company may condition delivery of
certificates for Shares upon the prior receipt from Grantee of any undertakings
which it may determine are required to assure that the certificates are being
issued in compliance with federal and state securities laws. The right to
payment of any fractional Shares shall be satisfied in cash, measured by the
product of the fractional amount times the fair market value of a Share on the
Vesting Date, as determined by the Committee.
