the Option may be exercised (to the extent that you would have been entitled to
do so at the date of your death) by your executor or administrator (or other
person at the time entitled by law to your rights under the Option) at any time
within one year after the date of death, but not after the Expiration Date.

9. Exercise of Option. The Option may be exercised by giving written notice in
the form specified by the Company to the Corporate Secretary at the principal
office of the Company specifying the number of shares of Applied Biosystems
Stock to be purchased. However, the Option may not be exercised as to fewer than
100 shares, or the remaining shares covered by the Option if fewer than 100, at
any one time, and the Option may not be exercised with respect to a fractional
share. The purchase price of the shares as to which the Option is exercised must
be paid in full at the time of exercise, at your election, (a) in U.S. currency,
(b) by tendering to the Company shares of Applied Biosystems Stock owned by you
for at least six months having a Fair Market Value equal to the aggregate
purchase price of the shares as to which the Option is being exercised, (c) a
combination of U.S. currency and/or previously owned shares of Applied
Biosystems Stock valued at Fair Market Value, or (d) by payment of such other
consideration as the Management Resources Committee of the Board of Directors
(the “Committee”) from time to time determines. For purposes of this paragraph,
Fair Market Value will be determined as of the business day immediately
preceding the day on which the Option is exercised.

10. Conditions to Exercise. The exercise of the Option within one year following
termination of employment is subject to the satisfaction of the conditions that
you have not (a) rendered services or engaged directly or indirectly in any
business which in the opinion of the Committee competes with or is in conflict
with the interests of the Company, or (b) violated any written agreement with
the Company, including, without limitation, any confidentiality agreement. Your
violation of either clause (a) or (b) of the preceding sentence will result in
the immediate forfeiture of any Options held by you.

11. Tax Withholding Obligations. As a condition to the delivery of shares of
Applied Biosystems Stock upon the exercise of the Option, you agree to pay to
the Company an amount sufficient to satisfy any applicable tax withholding
obligations. Alternatively, you agree that the Company and your employer are
expressly authorized to deduct the appropriate withholding taxes from your pay
in order to satisfy any income, social, or other employment-related taxes
related to your participation in the Plan.

the issuance to you of a certificate for such shares.

15. No Right to Continued Employment. Neither the Option nor this Agreement
confers upon you any right to continue to be an employee of the Company or any
of its subsidiaries or interferes in any way with the right of the Company or
any of its subsidiaries to terminate your employment at any time. Except as
provided in this Agreement, the Option will terminate upon the termination of
your employment for any reason. The Option will not be reinstated if you are
subsequently reinstated as an employee of the Company or any subsidiary.

16. No Right to Future Benefits. The Plan and the benefits offered thereunder
are provided by the Company on an entirely discretionary basis, and the Plan
creates no vested rights in participants. Neither the Option nor this Agreement
confers upon you any benefit other than as specifically set forth in this
Agreement and the Plan. You understand and agree that the benefits offered under
the Option and the Plan are not part of your salary and that receipt of the
Option does not entitle you to any future benefits under the Plan or any other
plan or program of the Company.

17. Compliance with Law. No shares of Applied Biosystems Stock will be issued
upon the exercise of the Option unless counsel for the Company is satisfied that
such issuance will be in compliance with all applicable laws.

governed by the terms of the Plan which is hereby incorporated by reference in
this Agreement. In the event of any ambiguity in this Agreement or any
inconsistency between the terms of this Agreement and the terms of the Plan, the
terms of the Plan will govern. By your signature below, you acknowledge receipt
