for the efficient performance of any of such Transitional Services.

           ---------------

subsidiaries or divisions.  Nothing in this Agreement shall require Du Pont to
favor the Business over its own businesses or those of any of its affiliates,
subsidiaries or divisions.

     (b)  Unless otherwise specifically set forth in the Appendixes attached
hereto, it is the intention of the parties that Dade's use of any Transitional
Service that Dade elects to use shall not be higher than the level of use
required by the Business prior to the acquisition thereof by Dade.   In no event
shall Dade be entitled to any new service or to increase its use of any of the
Transitional Services above that level of use without the prior written consent
of Du Pont, which consent may be withheld by Du Pont for any or no reason in its
sole and absolute discretion.

     (c)  Du Pont shall not be required to provide Dade extraordinary levels of

conditions of this Agreement.

     1.05  Limitation of Liability and Warranty. (a)  In the absence of gross
           ------------------------------------

judgments, court costs and reasonable attorneys' fees), fines and penalties,
arising out of any actual or alleged injury, loss or damage of any nature
whatsoever in providing or failing to provide the Transitional Services to Dade.
Notwithstanding anything to the contrary contained herein, in the event Du Pont
commits an error with respect to or incorrectly performs or fails to perform any
Transitional Service, at Dade's request, Du Pont shall use reasonable efforts to
correct such error, re-perform or perform such Transitional Service; provided,
                                                                     --------

the extent the same cannot be cured by the re-performance of the Transitional
Service in question.

providing the Transitional Services,  such goods shall be provided in accordance
with the conditions of sale set forth in Appendix C attached hereto and made a
                                         ----------                           
part hereof.  EXCEPT AS SET FORTH IN THOSE CONDITIONS, DUPONT MAKES NO EXPRESSED
OR IMPLIED WARRANTY (INCLUDING, WITHOUT LIMITATION, THE WARRANTIES OF
MERCHANTABILITY OR FITNESS FOR A PARTICULAR PURPOSE) REGARDING ANY GOODS
PROVIDED IN CONNECTION WITH THE TRANSITIONAL SERVICES.

     1.06  No Obligation to Continue to Use Services.  (a) Dade shall have no
           -----------------------------------------                         
obligation to continue to use any of the Transitional Services and may delete
any Transitional Service from the Transitional Services that Du Pont is
providing to Dade by giving Du Pont reasonable advance written notice of its
desire to delete any or all Transitional Services; provided, that the deletion

     (b) If any Transitional Service is deleted by Dade, Du Pont shall have the
option, in its sole and absolute discretion, to discontinue any Transitional
Service(s) related to such deleted Transitional Service(s) as set forth in

                                                        ------------

provide its computer and telecommunications services, if Dade is unable to fully
implement such migration plan.

     1.08  Du Pont Access.  To the extent reasonably required for Du Pont
           --------------

employees of the Business share office space with other businesses of Du Pont,
which office space is listed on Appendix D attached hereto (the "Additional
                                ----------                                 
Office Space"), and that the terms and conditions for the use of Additional
Office Space are not addressed in this Agreement because the Additional Office
Space is not significant.  Du Pont

                                      -5-

 
and Dade agree to negotiate in good faith to establish the terms and conditions
(including the cost thereof) upon which Dade may utilize the Additional Office
Space.

     1.10  Site Services Agreement.  Notwithstanding anything to the contrary
           -----------------------

                                   ARTICLE 2
                                  COMPENSATION
                                  ------------

     2.01  Consideration.  (a)  As consideration for the Transitional Services,
           -------------                                                       
Dade shall pay to Du Pont the amount specified for each Transitional Service as
set forth in Appendix A.  If the amount to be paid for any Transitional Service
             ----------                                                        
is described in Appendix A as "cost", the use of the term "cost" does not mean
                ----------                                                    
Du Pont's cost to provide that Transitional Service, but the cost to Dade to
receive such Transitional Service from Du Pont.  Upon the deletion of any
Transitional Service in accordance with Paragraph 1.06 above, the compensation
to be paid under this Paragraph 2.01 shall be reduced by the amount specified
for such deleted Transitional Service.  Upon the reduction of the level of, or
the termination, of any specific Transitional Service, Du Pont and Dade shall
determine in good faith a reduction of the amount to be paid by Dade hereunder
due to such reduction or termination.  Specifically, with respect to the Service
and Security Transitional Services for Europe, to the extent that Dade vacates a
facility, the price of such Transitional Service shall be reduced based upon the
square footage of the vacated space as it relates to the total square footage of
the space provided in connection with such Transitional Services.
 
     (b)  In addition to the payments described in subparagraph (a) above, Dade
shall reimburse to Du Pont an amount

                                      -6-

 
equal to the sum of (i) all of the costs, if any, required by any third party
incurred by Du Pont to obtain consents from such third parties to permit Du Pont
to provide any Transitional Service to Dade hereunder (including, without
limitation, amounts paid for the right to continue to use third party software
for the benefit of Dade) in accordance with the terms of Section 5.09(f) of the
Purchase Agreement, plus (ii) any expenditures made by Du Pont on behalf of Dade
pursuant to Appendix A.  Such costs and expenditures will be billed to Dade in
            ----------                                                        
the monthly invoice(s) described in Paragraph 2.03 below.  In the event that Du
Pont will be making any such disbursements of funds on behalf of Dade, before
any disbursement will be made, Dade shall deposit funds equal to an estimated
amount of such costs and expenditures into a bank account designated by Du Pont.

     2.02  Taxes.  Any taxes (other than income taxes) assessed on the provision
           -----                                                                
of the Transitional Services shall be paid by Dade.

     2.03  Invoices.  At the end of each month, each of Du Pont and its
           --------                                                    
affiliates or subsidiaries providing the Transitional Services will submit one
invoice to Dade for (a) all Transitional Services provided to Dade and its
subsidiaries by such entity, and (b) those costs and expenditures described in
Paragraph 2.01(b) above incurred by such entity during such month.  Such monthly
invoices shall be issued no later than the fifteenth day of each month.  Each
invoice shall include a summary list of the previously agreed upon Transition
Service for which there are fixed dollar fees, together with documentation
supporting each of the invoiced amounts that are not covered by the fixed fee
agreements.  The total of this list and supporting detail will equal the invoice
total, and will be provided under separate cover apart from the invoice.  All
invoices shall be sent to Dade at the following address or to such other address
as Dade shall have specified by notice in writing to Du Pont:

payment sent by facsimile to the person stipulated in the invoice or otherwise
in writing to Dade by Du Pont.

     (b)  If any payment is not paid when due, Du Pont shall have the right,
without any liability to Dade, or anyone claiming by or through Dade, to
immediately cease providing either all of the Transitional Services, or the
Transitional Service(s) for which payment has not been made within ten (10)
business days after the delivery of written notice thereof delivered in
accordance with Section 6.04 below, which right may be exercised by Du Pont in
its sole and absolute discretion, and shall not limit or otherwise affect Du
Pont's right to terminate this Agreement in accordance with Article 4 below.

                                CONFIDENTIALITY

consent of the other Party, each Party shall hold in confidence and not disclose
to any third party (i) any confidential information received by it from the
other Party during the provision of the Transitional Services, including,
without limitation, information which is not related to the Transitional
Services; and (ii) with regard to Dade, the specific terms, conditions and
information contained in this Agreement and any attachment hereto.

     (b)  Each party agrees that it shall only use the information received by

it from the other Party in connection with the provision or receipt of the
Transitional Services, and for no other purpose whatsoever.

     (c)  For the purposes of this Agreement, confidential information shall not
include information:

          (i)    which is or becomes part of the public domain other than
through breach of this Agreement or through the fault of the receiving Party;

          (ii)   which is or becomes available to the receiving Party from a

                                      -9-

 
notice to the Defaulting Party specifying the nature of such failure or default
and stating that the Non-Defaulting Party intends to terminate this Agreement if

Defaulting Party against the Defaulting Party.

     (b)  Notwithstanding the provisions of subparagraph (a) above, Du Pont may

           ------------------------------------------                         
that Du Pont is providing the Transitional Services as an accommodation to Dade
to allow Dade a period of time to obtain its own administrative and support
services.  During the term of this Agreement, Dade agrees that, in addition to
the migration plan described in Paragraph 1.07(d), it shall take all steps
necessary to obtain its own administrative and support

termination of this Agreement.  Upon the ceasation of Du Pont's obligation to
provide any Transitional Service, Dade shall immediately cease using, directly
or indirectly, such Transitional Service (including, without limitation, any and
all Du Pont software or third party software provided through Du Pont,
telecommunications services or equipment, or computer systems or equipment).
Dade hereby agrees that Du Pont will experience a negative impact on Du Pont's
businesses in providing any Transitional Service beyond the Time Period
specified for such Transitional Service (and any extension thereof in accordance
with Section 4.02).

     (c)  DUPONT SHALL HAVE NO LIABILITY OF ANY KIND OR NATURE WHATSOEVER
(INCLUDING, WITHOUT LIMITATION, INDIRECT, CONSEQUENTIAL, SPECIAL, INCIDENTAL OR
PUNITIVE DAMAGES) TO DADE, OR TO ANYONE CLAIMING BY OR THROUGH DADE, FOR
DUPONT'S CEASING TO PROVIDE ANY TRANSITIONAL SERVICE UPON THE EXPIRATION OF THE

LIABILITY AGAINST DUPONT OR DUPONT'S EMPLOYEES, AGENTS, ASSIGNEES, SUBSIDIARIES
OR AFFILIATES ARISING OUT OF DUPONT'S CEASING TO PROVIDE ANY TRANSITIONAL
SERVICE UPON THE EXPIRATION OF THE TIME PERIOD (AND ANY EXTENSION THEREOF IN
ACCORDANCE WITH SECTION 4.02) FOR SUCH TRANSITIONAL SERVICE OR THE TERMINATION
