        This Appendix ("Appendix") is adopted as part of the Beckman Coulter,
Inc. Executive Deferred Compensation Plan (the "Deferred Compensation Plan").
Pursuant to the Amendment to Asset Purchase Agreement and the Second Amendment
to Asset Purchase Agreement (collectively, the "Amendment") by and between
Beckman Coulter, Inc. ("BCI") and Saphfire, Inc. ("Saphfire"), BCI is to
establish a deferred compensation plan (the "Plan") for the purpose of crediting
certain payments to be made to Key Employees under the Amendment. This Appendix,
when read together with the Deferred Compensation Plan, constitute the Plan for
purposes of the Amendment.

        The adoption of this Appendix is authorized by the Committee under the
Deferred Compensation Plan as an amendment to the Deferred Compensation Plan,
pursuant to the authority contained in Section 9.6 of the Deferred Compensation
Plan.

     1. ESTABLISHMENT OF SUB-ACCOUNTS. Sub-accounts shall be established by the
the Company as part of the Stock Unit Account and Cash Deferral Account under
the Deferred Compensation Plan for each of the Key Employees.

     2. CREDITING PURSUANT TO SECTIONS 1.2.1 AND 1.2.2 OF AMENDMENT. As of the
dates specified in Section 1.2.1 and 1.2.2 of the Amendment, Company shall
credit to the appropriate sub-account of each Key Employee Units representing
the amount determined under the Amendment. Each Key employee shall elect whether
such amounts shall be credited to the





Stock Unit Account or Cash Deferral Account; a separate election shall be made
for the amounts under Sections 1.2.1 and 1.2.2.

               (a) If the Key Employee elects that such amount shall be credited
        to the Stock Unit Account, the number of Units credited to the
        sub-account of the Key Employee shall be the amount determined under the
        Amendment for such Key Employee, divided by the Fair Market Value of a
        share of Common Stock as of the date Units are credited to the
        sub-account. The Company shall designate the portion of such credit
        which constitutes the "deferred compensation" portion and the "premium"
        portion, as specified in the Amendment.

               (b) If the Key Employee so elects, the amount determined under
        the Amendment which constitutes the "deferred compensation" portion, as
        specified in the Amendment, shall be credited to the Cash Deferral
        Account. For such a Key Employee, no amount shall be credited as the
        "premium" portion, as specified in the Amendment.

     3. CREDITING PURSUANT TO SECTION 1.2.3 OF AMENDMENT. As of March 31, 2003,
for each Key Employee who elected to have the amount specified in Section 1.2.3
of the Amendment credited to a cash deferral account, the Company shall credit
such amount to the sub-account of the Cash Deferral Account established for such
Key Employee. As specified in Sections 1.3 and 1.3.1 of the Amendment, the
amounts which would otherwise be credited to a Key Employee under paragraphs
1.2.1, 1.2.2, and 1.2.3 of the Amendment are not to be credited if a forfeiture
occurs with respect to such Key Employee. Furthermore, as set forth in Section
1.3.2 of the Amendment, BCI may pay certain amounts to Key Employees upon
termination of

Section 1.3.2, then such amount shall not be credited under the
Deferred Compensation Plan.

     4. FICA TAXES. The amounts credited under Sections 2 and 3 of this Appendix
shall be net of FICA taxes and income taxes withheld on such FICA taxes.

     5. SPECIAL VESTING RULE. Notwithstanding Section 5.1 of the Deferred
Compensation Plan, for a Key Employee who elects that amounts shall be credited
to the Stock Unit Account under paragraph 2 of this Appendix, the "premium"
portion of the "First Amount" (as defined in Section 1.2.1 of the Amendment) and
the "premium" portion of the "Second Amount" (as defined in Section 1.2.2 of the
Amendment) will be subject to the vesting requirements set forth in the
Amendment. If such a Key Employee does not satisfy such vesting requirements,
the amounts credited to such Key Employee's sub-account as the "premium"
portions shall be forfeited as set forth in the Amendment.

     6. DIVIDEND EQUIVALENTS AND EARNINGS. For a Key Employee who elects that
amounts shall be credited to the Stock Unit Account, Dividend Equivalents shall
be credited to the sub-account of the Stock Unit Account established for such
Key Employee, as set forth in Section 4.2(f) of the Deferred Compensation Plan.

according to the elections submitted by each Key Employee
applicable to the amounts subject to this Appendix. Notwithstanding the
foregoing, however, the "premium" portion (within the meaning of Section 1.2.1
and Section 1.2.2 of the Amendment) attributable to a Key Employee (if any)

Employee; if such amounts become vested, such amounts shall be distributed as
soon as feasible following the later of the date such amount become vested or
the date distribution would otherwise be made under the Key Employee's election.
