     1. PLAN INCORPORATED BY REFERENCE. THIS OPTION IS ISSUED PURSUANT TO THE
TERMS OF THE PLAN AND MAY BE AMENDED AS PROVIDED IN THE PLAN. CAPITALIZED TERMS
USED AND NOT OTHERWISE DEFINED IN THIS CERTIFICATE HAVE THE MEANINGS GIVEN TO
THEM IN THE PLAN. THIS CERTIFICATE DOES NOT SET FORTH ALL OF THE TERMS AND
CONDITIONS OF THE PLAN, WHICH ARE INCORPORATED HEREIN BY REFERENCE. THE
COMMITTEE ADMINISTERS THE PLAN AND ITS DETERMINATIONS REGARDING THE OPERATION OF
THE PLAN ARE FINAL AND BINDING. COPIES OF THE PLAN MAY BE OBTAINED UPON WRITTEN
REQUEST WITHOUT CHARGE FROM THE SHAREHOLDER RELATIONS DEPARTMENT OF THE COMPANY.

     2. OPTION PRICE. THE PRICE TO BE PAID FOR EACH SHARE OF COMMON STOCK ISSUED
UPON EXERCISE OF THE WHOLE OR ANY PART OF THIS OPTION IS THE OPTION PRICE SET
FORTH ON THE FACE OF THIS CERTIFICATE (THE "OPTION PRICE").

     3. EXERCISABILITY SCHEDULE. THIS OPTION MAY BE EXERCISED AT ANY TIME AND
FROM TIME TO TIME UP TO THE NUMBER OF SHARES AND IN ACCORDANCE WITH THE
EXERCISABILITY SCHEDULE SET FORTH ON THE FACE OF THIS CERTIFICATE, BUT ONLY FOR

DEFERRED EXERCISE PERIOD. [ NOTWITHSTANDING THE FOREGOING, IN THE EVENT OF A
CHANGE IN CONTROL OF THE COMPANY (AS DEFINED IN A VOTE OF THE COMPENSATION
COMMITTEE ADOPTED MAY 29, 2002), THIS OPTION SHALL BECOME EXERCISABLE AS TO ALL
SHARES WITHOUT REGARD TO ANY DEFERRED EXERCISABILITY SCHEDULE OR DEFERRED

     6. OPTION NOT TRANSFERABLE. THIS OPTION IS NOT TRANSFERABLE BY THE
PARTICIPANT OTHERWISE THAN BY WILL OR THE LAWS OF DESCENT AND DISTRIBUTION, AND
IS EXERCISABLE, DURING THE PARTICIPANT'S LIFETIME, ONLY BY THE PARTICIPANT. THE
NAMING OF A DESIGNATED BENEFICIARY DOES NOT CONSTITUTE A TRANSFER.

     7. EXERCISE OF OPTION AFTER TERMINATION OF EMPLOYMENT. IF THE PARTICIPANT'S
EMPLOYMENT WITH (a) THE COMPANY, (b) AN AFFILIATE, OR (c) A CORPORATION (OR
PARENT OR SUBSIDIARY CORPORATION OF SUCH CORPORATION) ISSUING OR ASSUMING A
STOCK OPTION IN A TRANSACTION TO WHICH SECTION 424(a) OF THE CODE APPLIES, IS
TERMINATED FOR ANY REASON OTHER THAN BY DISABILITY (WITHIN THE MEANING OF
SECTION 22(e)(3) OF THE CODE), DEATH OR RETIREMENT, THE PARTICIPANT MAY EXERCISE
THE RIGHTS WHICH WERE AVAILABLE TO THE PARTICIPANT AT THE TIME OF SUCH
TERMINATION ONLY WITHIN THREE MONTHS FROM THE DATE OF TERMINATION. IF
PARTICIPANT'S EMPLOYMENT IS TERMINATED AS A RESULT OF DISABILITY, THIS OPTION
SHALL BECOME EXERCISABLE AS TO ALL SHARES WITHOUT REGARD TO ANY DEFERRED
EXERCISE PERIOD, AND SUCH RIGHTS MAY BE EXERCISED WITHIN TWELVE MONTHS FROM THE
DATE OF TERMINATION. IF PARTICIPANT'S EMPLOYMENT IS TERMINATED AS A RESULT OF
RETIREMENT (WHICH IS DEFINED AS A MINIMUM OF AGE 60 PLUS A MINIMUM OF FIVE YEARS

THIS OPTION SHALL BECOME EXERCISABLE AS TO ALL SHARES WITHOUT REGARD TO ANY
DEFERRED EXERCISE PERIOD, AND HIS OR HER DESIGNATED BENEFICIARY SHALL HAVE THE
RIGHT, AT ANY TIME WITHIN TWELVE MONTHS AFTER THE DATE OF DEATH, TO EXERCISE IN
WHOLE OR IN PART ANY RIGHTS THAT WERE AVAILABLE TO THE PARTICIPANT AT THE TIME
OF DEATH. NOTWITHSTANDING THE FOREGOING, NO RIGHTS UNDER THIS OPTION MAY BE
EXERCISED AFTER THE EXPIRATION DATE.

     8. COMPLIANCE WITH SECURITIES LAWS. IT SHALL BE A CONDITION TO THE
PARTICIPANT'S RIGHT TO PURCHASE SHARES OF COMMON STOCK HEREUNDER THAT THE
COMPANY MAY, IN ITS DISCRETION, REQUIRE (a) THAT THE SHARES OF COMMON STOCK
RESERVED FOR ISSUE UPON THE EXERCISE OF THIS OPTION SHALL HAVE BEEN DULY LISTED,
UPON OFFICIAL NOTICE OF ISSUANCE, UPON ANY NATIONAL SECURITIES EXCHANGE OR
AUTOMATED QUOTATION SYSTEM ON WHICH THE COMPANY'S COMMON STOCK MAY THEN BE
LISTED OR QUOTED, (b) THAT EITHER (i) A REGISTRATION STATEMENT UNDER THE
SECURITIES ACT OF 1933 WITH RESPECT TO THE SHARES SHALL BE IN EFFECT, OR (ii) IN
THE OPINION OF COUNSEL FOR THE COMPANY, THE PROPOSED PURCHASE SHALL BE EXEMPT
FROM REGISTRATION UNDER THAT ACT AND THE PARTICIPANT SHALL HAVE MADE SUCH
UNDERTAKINGS AND AGREEMENTS WITH THE COMPANY AS THE COMPANY MAY REASONABLY
REQUIRE, AND (c) THAT SUCH OTHER STEPS, IF ANY, AS COUNSEL FOR THE COMPANY SHALL
CONSIDER NECESSARY TO COMPLY WITH ANY LAW APPLICABLE TO THE ISSUE OF SUCH SHARES
BY THE COMPANY SHALL HAVE BEEN TAKEN BY THE COMPANY OR THE PARTICIPANT, OR BOTH.
THE CERTIFICATES REPRESENTING THE SHARES PURCHASED UNDER THIS OPTION MAY CONTAIN
SUCH LEGENDS AS COUNSEL FOR THE COMPANY SHALL CONSIDER NECESSARY TO COMPLY WITH
ANY APPLICABLE LAW.

     9. PAYMENT OF TAXES. THE PARTICIPANT SHALL PAY TO THE COMPANY, OR MAKE
PROVISION SATISFACTORY TO THE COMPANY FOR PAYMENT OF ANY TAXES REQUIRED BY LAW
TO BE WITHHELD WITH RESPECT TO THE EXERCISE OF THIS OPTION. THE COMMITTEE MAY,
IN ITS DISCRETION, REQUIRE ANY OTHER FEDERAL OR STATE TAXES IMPOSED ON THE SALE
OF THE SHARES TO BE PAID BY THE PARTICIPANT. IN THE COMMITTEE'S DISCRETION, SUCH
TAX OBLIGATIONS MAY BE PAID IN WHOLE OR IN PART IN SHARES OF COMMON STOCK,
INCLUDING SHARES RETAINED FROM THE EXERCISE OF THIS OPTION, VALUED AT THEIR FAIR
MARKET VALUE ON THE DATE OF DELIVERY. THE COMPANY AND ITS AFFILIATES MAY, TO THE
EXTENT PERMITTED BY LAW, DEDUCT ANY SUCH TAX OBLIGATIONS FROM ANY PAYMENT OF ANY
KIND OTHERWISE DUE TO THE PARTICIPANT.

     10. NOTICE OF SALE OF SHARES REQUIRED. THE PARTICIPANT AGREES TO NOTIFY THE
COMPANY IN WRITING WITHIN 30 DAYS OF THE DISPOSITION OF ANY SHARES PURCHASED
UPON EXERCISE OF THIS OPTION IF SUCH DISPOSITION OCCURS WITHIN TWO YEARS OF THE
DATE OF THE GRANT OF THIS OPTION OR WITHIN ONE YEAR AFTER SUCH PURCHASE.

     11. RIGHTS LIMITED. THE COMMITTEE, IN ITS SOLE DISCRETION, SHALL DETERMINE
FROM THE GROUP OF ELIGIBLE PERSONS WHETHER AN INDIVIDUAL SHALL BE A PARTICIPANT
UNDER THE PLAN. ANY OPTION GRANT MADE UNDER THE PLAN SHALL BE MADE IN THE SOLE
DISCRETION OF THE COMMITTEE, OR ITS DELEGATE AS APPOINTED IN ACCORDANCE WITH THE
PLAN, AND NO PRIOR OPTION GRANT SHALL ENTITLE A PERSON TO ANY FUTURE AWARD. IN
NO EVENT SHALL THE PLAN, OR ANY OPTION GRANT MADE UNDER THE PLAN, FORM A PART OF
AN EMPLOYEE'S OR CONSULTANT'S CONTRACT OF EMPLOYMENT OR SERVICE, IF ANY. NEITHER
THE PLAN, NOR ANY OPTION GRANT MADE UNDER THE PLAN, SHALL CONFER UPON ANY
EMPLOYEE OR CONSULTANT OF THE COMPANY OR ITS AFFILIATE ANY RIGHT WITH RESPECT TO
THE CONTINUANCE OF HIS OR HER EMPLOYMENT BY, OR OTHER SERVICE WITH, THE COMPANY
OR ITS AFFILIATE, NOR SHALL THEY LIMIT THE RIGHTS OF THE COMPANY OR ITS
AFFILIATE TO TERMINATE THE EMPLOYEE OR CONSULTANT OR OTHERWISE CHANGE THE TERMS
OF SERVICE. NO PARTICIPANT OR DESIGNATED BENEFICIARY SHALL HAVE ANY RIGHTS AS A
SHAREHOLDER WITH RESPECT TO ANY SHARES OF COMMON STOCK TO BE ISSUED UNDER THE
PLAN OR ANY OPTION UNTIL HE OR SHE BECOMES THE HOLDER THEREOF. THE LOSS OF
EXISTING OR POTENTIAL PROFIT IN AN OPTION GRANT SHALL NOT CONSTITUTE AN ELEMENT
OF DAMAGES IN THE EVENT OF TERMINATION OF EMPLOYMENT OR SERVICE FOR ANY REASON,
EVEN IF THE TERMINATION IS IN VIOLATION OF AN OBLIGATION OF THE COMPANY OR ITS
AFFILIATE TO THE PARTICIPANT.

     12. ACCEPTANCE. FAILURE OF THE PARTICIPANT TO ACCEPT THE TERMS AND
CONDITIONS OF THIS OPTION IN ACCORDANCE WITH THE REQUIREMENTS OF THE COMMITTEE
OR ITS DELEGATE, AS APPLICABLE, CAN RESULT IN ADVERSE CONSEQUENCES TO THE
PARTICIPANT, INCLUDING CANCELLATION OF THE OPTION.
