restatement in its entirety to read as follows:

(g) Modification, Extension And Renewal of Options. The Committee shall
have the power to modify, cancel, extend or renew outstanding Options and to
authorize the grant of new Options and/or Restricted Stock Awards in

a repricing for financial accounting or other purposes), provided that (except
as permitted by Section 11 of this Plan) any such action may not, without the
written consent of any Optionee, impair any rights under any Option previously
granted to such Optionee. Any outstanding Incentive Stock Option that is
modified, extended, renewed or otherwise altered will be treated in accordance
with Section 424(h) of the Code.
