You will also be eligible to participate in the Dade Behring long-term incentive
plan, the plan established by the Board of Directors for senior executives of
the company. Upon acceptance of this employment offer, Dade Behring will
recommend to the Board of Directors that you will be granted 275,000
non-qualified stock options with a strike price of $15.00 per share. This strike
price has been discounted by 10%/$1.55 from the company's June 30, 1999 share
repurchase price of $16.55. These options will vest over a five-year period in
20% increments. The first 20%/55,000 options will vest on July 1, 2001. You will
be provided with additional information, including a plan document and brochure
after formal approval by the Board.

As a member of the Executive Leadership Team, you will be eligible to
participate in Dade Behring's Executive Financial Planning and Legal Services
Program. This Program has been designed to provide you with comprehensive
individual financial consulting, personal tax return preparation assistance and
legal consultation services. The grossed up annual value of this benefit is
approximately $12,750 ($7,500 net) for Financial Planning and $4,250 ($2,500
net) for Legal Services. Attached for your reference is a summary of the
Program.

You will also be entitled to a car allowance of $1,000 per month.

You will be eligible for four weeks of vacation annually under Dade Behring's
executive vacation program.

You will be relocating to the Deerfield, Illinois area and will be entitled to
Dade Behring's executive relocation package. As an exception, your temporary
apartment may be extended up to nine months. All relocation activity should be
completed within one year of the effective date in your new position, however,
Jeff, you and I will assess your relocation status at the one year point and
decide on appropriate next steps. Due to the considerable expenses Dade Behring
incurs when a relocation occurs, you will be required to sign a Relocation
Repayment Agreement. A copy of the program and the relocation repayment
agreement are enclosed for your review.

You and your dependents will be eligible to participate in the various Dade
Behring employee benefit plans. A benefits overview brochure is enclosed for
your review. You will receive Dade Behring Employee Benefit Program enrollment
information from the Employee Benefits Center within one month of your start
date. Should you choose to elect health insurance coverage, it will be effective
on the first of the month following thirty days of employment. Our Human
Resources staff is available to assist you with any questions you may have in
the interim.

This offer, if accepted, would create an employment-at-will relationship between
you and Dade Behring. It is not intended nor should it be construed as a
contract of continued employment.
