DONAL QUINN SUPPLEMENTAL PENSION ARRANGEMENT

Dade Behring has agreed to provide Donal Quinn with a supplemental pension. In
addition we have agreed to a special guarantee with regard to his pension
accrual in accordance with the terms of his remuneration package. With regard to
the supplemental pension:

     If your employment with Dade Behring continues in good standing until
     January of 2009, the company will provide you with a supplemental pension
     arrangement in the amount of DEM 500,000 to be credited to your German
     pension plan in 10 equal annual installments of DEM 50,000 beginning in
     January of 2000. Each annual installment will be fully vested once credited
     to your German supplemental pension plan.

In addition, we have agreed that in the event that he terminates employment
prior to completing ten years of service with Dade Behring and forfeits his
company provided benefit under the Pensionkasse arrangement, the company will
provide him with a retirement benefit equivalent to the company-paid amount he
would have received had he been fully vested in the benefit accrued to the date
of his termination of employment. This benefit would be payable at the time
Donal Quinn would otherwise be eligible to receive a retirement benefit (normal
retirement age- 60) and would be payable in the form of an annuity, the same
form as a benefit payable from the Pensionkasse. It would not include any
amounts based on Donal Quinn's own contributions that would be returned to him
upon his termination of employment. I assume the Pensionkasse could calculate
the benefit for us based on the company's contribution obligation for whatever
period of time Mr. Quinn is actually employed.

This payment is contingent on Mr. Quinn terminating prior to achieving ten years
of service with Dade Behring (July, 2008). If he remains in employment with the
company or its successor and becomes eligible for a benefit under the
Pensionkasse, this portion of the agreement will become obsolete.<Page>

                               DADE INTERNATIONAL
                            SUPPLEMENTAL PENSION PLAN

1.     PURPOSE

The Dade International Pension Plan (the "Pension Plan") is a defined benefit
pension plan maintained by Dade International Inc. (the "Corporation") to
assist in providing participants with retirement benefits. The retirement
benefit of each participant is determined based on formulae set forth in the
Pension Plan. Certain provisions of the Internal Revenue Code of 1986, as
amended (the "Code") preclude some participants from receiving the full
retirement benefit otherwise earned under the Pension Plan formulae.
Accordingly, the Corporation has adopted the Dade International Supplemental
Pension Plan (the "Supplemental Plan"), effective January 1, 1995. The sole
purpose of the Supplemental Plan is to enable certain participants in the
Pension Plan to receive the difference between the retirement benefit actually
payable to them under the Pension Plan and the retirement benefit they would
otherwise have earned under the Pension Plan formulae absent the limitations
described above.

2.     DEFINITIONS

       (a)    "Accrued Benefit" has the meaning ascribed to that term in the
              Pension Plan.

       (b)    "Administrative Committee" has the meaning ascribed to that term
              in the Pension Plan.

       (c)    "Board of Directors" has the meaning ascribed to that term in the
              Pension Plan.

       (d)    "Compensation" has the meaning ascribed to that term in the
              Pension Plan.

       (e)    "Excess Amount" means the difference between the Accrued Benefit
              payable to a Participant from the Pension Plan and the Accrued
              Benefit that would be payable to the Participant if the
              limitations of Sections 15.10 and 15.11 of the Pension Plan as
              well as the limitations under Section 401(a)(17) of the Code were
              disregarded.

       (f)    "Participant" means a vested participant in the Pension Plan who
              is designated from time to time by the Administrative Committee as
              a participant in the Plan and whose Accrued Benefit payable from
              the Pension Plan is limited solely because of the application of

<Page>

              Sections 15.10 and 15.11 of the Pension Plan or the application of
              Section 401(a)(17) of the Code (the name of each such Participant
              having been set forth on Attachment 1 hereto).

       (g)    "Plan Year" has the meaning ascribed to that term in the Pension
              Plan.

       (h)    "Termination of Employment" has the meaning ascribed to that term
              in the Pension Plan.

3.     CREDITED AMOUNTS

The Excess Amount of each Participant shall be credited to a book reserve
account of the Corporation. All credited amounts shall be general obligations of
the Corporation and the Corporation shall not be required to set up a funded
reserve, or otherwise set aside specific funds for the payment of its
obligations under the Supplemental Plan. Nothing contained herein shall be
deemed to create a trust or create a fiduciary relationship with respect to such
credited amounts. The Corporation shall retain title to and beneficial ownership
of any assets which may be used to pay the credited amounts. The right of a
Participant to receive payment under the Supplemental Plan shall be no greater
than the right of any unsecured creditor of the Corporation. The right of any
Participant to payment of credited amounts under the Supplemental Plan shall not
be subject to sale, transfer, assignment, pledge or encumbrance.

4.     DISTRIBUTIONS

Distribution of the Excess Amount to a Participant shall me made at the same
time and in the same manner as distribution of his Accrued Benefit from the
Pension Plan. Notwithstanding the preceding sentence, the Administrative
Committee shall have the authority to defer distribution of the Excess Amount
for a period of up to twelve months after the Participant's distribution from
the Pension Plan commences, as determined in the sole discretion of the
Administrative Committee.

5.     ADMINISTRATION

The Administrative Committee shall have full power and authority to construe and
administer the Supplemental Plan, and the Administrative Committee's
construction, administration and actions under the Supplemental Plan shall be
binding and conclusive on all persons for all purposes.

                                      - 2 -

6.     TAXATION

It is intended that each Participant shall be taxed on all amounts credited to
him under the Supplemental Plan at the time such amounts are received, and the
provisions of the Supplemental Plan shall be interpreted consistent with that
intention.

7.     AMENDMENT/TERMINATION

The Board of Directors has the right to amend or terminate the Supplemental Plan
at any time, provided that no such amendment or termination shall affect any
amounts credited to a Participant under the Supplemental Plan as of the date of
such amendment or termination.

        NOW, THEREFORE, the parties agree to amend the Credit Agreement as follows: 

        1.    Unless
otherwise defined herein all defined terms used herein shall have the same meaning as ascribed to such terms in the Credit Agreement. 

        2.    The
Lenders have agreed among themselves to reallocate their respective Commitments and to allow Union Bank of California, N.A. to acquire an interest in the Commitments
and the Loans. After such reallocation of the Commitments, the Lenders shall own the Revolving Commitment Percentages set forth on Schedule 1 hereto at the Amendment Effective Date. Each Lender

        4.    Except
to the extent its provisions are specifically amended, modified or superseded by this Amendment and all previous Amendments, the representations, warranties and
affirmative and negative covenants of the Borrowers contained in the Credit Agreement are incorporated herein by reference for all purposes as if copied herein in full. The Borrowers hereby restate
and reaffirm each and every term and provision of the Credit Agreement, as amended, including, without limitation, all representations, warranties and affirmative and negative covenants. Except to the
extent its provisions are specifically amended, modified or superseded by this Amendment, the Credit Agreement, as 

 

amended, and all terms and provisions thereof shall remain in full force and effect, and the same in all respects are confirmed and approved by the Borrowers and the Lenders. 

        5.    This
Amendment shall be effective as of the date first above written (the "Amendment Effective Date"), but only upon the satisfaction of the conditions precedent set
forth in Paragraph 6 hereof. 

        6.    The
obligations of Lenders under this Amendment shall be subject to the following conditions precedent: 

        (a)    Execution and Delivery.    The Borrowers shall have executed and delivered this Amendment, and other required
documents, all in form and substance satisfactory to the Agent; 

        (b)    Representations and Warranties.    The representations and warranties of the Borrowers under this Amendment are
true and correct in all material respects as of such date, as if then made (except to the extent that such representations and warranties related solely to an earlier date); 

        (c)    No Event of Default.    No Event of Default shall have occurred and be continuing nor shall any event have
occurred or failed to occur which, with the passage of time or service of notice, or both, would constitute an Event of Default; 

        (d)    Other Documents.    The Agent shall have received such other instruments and documents incidental and
appropriate to the transaction provided for herein as the Agent or its counsel may reasonably request, and all such documents shall be in form and substance satisfactory to the Agent; 

        (e)    Legal Matters Satisfactory.    All legal matters incident to the consummation of the transactions contemplated
hereby shall be reasonably satisfactory to special counsel for the Agent retained at the expense of Borrowers. 

        7.    Borrowers
hereby represent and warrant that all factual information heretofore and contemporaneously furnished by or on behalf of Borrowers to Agent for purposes of or in
connection with this Amendment does not contain any untrue statement of a material fact or omit to state any material fact necessary to keep the statements contained herein or therein from being
misleading. Each of the foregoing representations and warranties shall constitute a representation and warranty of Borrowers made under the Credit Agreement, and it shall be an Event of Default if any
such representation and warranty shall prove to have been incorrect or false in any material respect at the time given. Each of the representations and warranties made under the Credit Agreement
(including those made herein) shall survive and not be waived by the execution and delivery of this Amendment or any investigation by Lenders. 

        8.    The
Borrowers agree to indemnify and hold harmless the Lenders and their respective officers, employees, agents, attorneys and representatives (singularly, an
"Indemnified Party", and collectively, the "Indemnified Parties") from and against any loss, cost, liability, damage or expense (including the reasonable fees and out-of-pocket
expenses of counsel to the Lender, including all local counsel hired by such counsel) ("Claim") incurred by the Lenders in investigating or preparing for, defending against, or
providing evidence, producing documents or taking any other action in respect of any commenced or threatened litigation, administrative proceeding or investigation under any federal securities law,
federal or state environmental law, or any other statute of any jurisdiction, or any regulation, or at common law or otherwise, which is alleged to arise out of or is based upon any acts, practices or
omissions or alleged acts, practices or omissions of the Borrowers or their agents or arises in connection with the duties, obligations or performance of the Indemnified Parties in negotiating,
preparing, executing, accepting, keeping, completing, countersigning, issuing, selling, delivering, releasing, assigning, handling, certifying, processing or receiving or taking any other action with
respect 

2

 

to the Loan Documents and all documents, items and materials contemplated thereby even if any of the foregoing arises out of an Indemnified Party's ordinary negligence. The indemnity set forth herein
shall be in addition to any other obligations or liabilities of the Borrowers to the Lenders hereunder or at common law or otherwise, and shall survive any termination of this Amendment, the
expiration of the Loan and the payment of all indebtedness of the Borrowers to the Lenders hereunder and under the Notes, provided that the Borrowers shall have no obligation under this section to the
Lenders with respect to any of the foregoing arising out of the gross negligence or willful misconduct of the Lenders. If any Claim is asserted against any Indemnified Party, the Indemnified Party
shall endeavor to notify the Borrowers of such Claim (but failure to do so shall not affect the indemnification herein made except to the extent of the actual harm caused by such failure). The
Indemnified Party shall have the right to employ, at the Borrowers' expense, counsel of the Indemnified Parties' choosing and to control the defense of the Claim. The Borrowers may at their own
expense also participate in the defense of any Claim. Each Indemnified Party may employ separate counsel in connection with any Claim to the extent such Indemnified Party believes it reasonably
prudent to protect such Indemnified Party. The parties intend for the provisions of this Section to apply to and protect each Indemnified Party from the consequences of strict
liability imposed or threatened to be imposed on any Indemnified Party as well as from the consequences of its own negligence, whether or not that negligence is the sole, contributing, or concurring
cause of any Claim.

        9.    This
Amendment may be executed in any number of counterparts and all of such counterparts taken together shall be deemed to constitute one and the same instrument. 

        10.  WRITTEN CREDIT AGREEMENT. THE CREDIT AGREEMENT, AS AMENDED BY THIS AMENDMENT REPRESENTS THE FINAL AGREEMENT BETWEEN AND
AMONG THE PARTIES AND MAY NOT BE CONTRADICTED BY EVIDENCE OF PRIOR, CONTEMPORANEOUS OR SUBSEQUENT ORAL AGREEMENTS OF THE PARTIES. THERE ARE NO UNWRITTEN ORAL AGREEMENTS BETWEEN AND AMONG THE PARTIES. 

        11.    New Lenders.    Union Bank of California, N.A. hereby agrees to become a Lender under the Credit Agreement, to
acquire the Commitment Percentage in the Commitments and the Loans as set forth on the signature page hereto and to be bound as a Lender by all of the provisions of the Credit Agreement. The Borrowers
and the Agent hereby consent to an assignment of a portion of the Commitment to Union Bank of California, N.A.
