                                  ARTICLE II
                          RESPONSIBILITIES OF SELLERS

                  2.01. Provision of Transition Employees. Subject to the terms
                        ---------------------------------
and conditions hereof, Sellers shall use their reasonable best efforts to
provide to Buyer during the Transition Period the services of the Transition
Employees, to devote their full time and energy to perform the functions and
services that were performed by the Transition Employees in the Toolbox Products
Distribution Business immediately prior to the Transition Period, or such other
functions that Sellers, in consultation with Buyer, may direct.

                  2.02. Status of Transition Employees. All Transition Employees
                        ------------------------------
providing services to Buyer under this Agreement shall at all times during the
Transition Period remain at-will employees of Sellers; provided that Buyer shall
                                                       -------- ----
have the right to request that Sellers remove any Transition Employee as a
service provider to Buyer (at which time any such employee shall cease to be a
Transition Employee); provided, further, that while Sellers shall have the
                      --------  -------
ultimate authority to make all employee-related decisions, they shall make all
reasonable efforts to accommodate Buyer's needs and desires in operating the
Toolbox Products Distribution Business.

                  2.03. Independent Contractor Relationship. (a) Notwithstanding
                        -----------------------------------
any provision hereof to the contrary, nothing herein shall be construed as
giving Buyer primary direction or control over the judgment of a Transition
Employee or the time, location, manner or method in which he or she performs the
services hereunder. The parties stipulate and agree that (i) each Transition
Employee is employed solely by one of the Sellers and not by Buyer, (ii) each
Seller and each Transition Employee is an independent contractor with respect to
his or her duties at Buyer; (iii) this Agreement identifies the work to be
performed by Sellers and its employees, but does not reserve to Buyer primary
direction or control in the time, location, manner or method in which such
services are to be performed; and (iv) Buyer shall not exercise and shall have
no right to designate which services are to be performed by particular
Transition Employees. This Agreement sets forth services to be provided by
Sellers and standards to be satisfied, but does not create the relationship of
an employer and employee as between Buyer and the Transition Employees. All
Transition Employees shall be and remain employees of Sellers and may be
promoted, disciplined, transferred or discharged only by Sellers. Buyer may
consult with Sellers in the discipline of a Transition Employee and may report
any professional,
<PAGE>

technical or other deficiencies in such Transition Employee's performance.

                  (b) Neither Sellers nor Buyer shall represent to any party
that any Transition Employee is an employee of Buyer, or that such Transition
Employee's relationship to Buyer is other than that of an independent
contractor.

                  (c) During the Transition Period, the Transition Employees
shall not participate in any employee benefit plan maintained, sponsored or
contributed to or for the benefit of Buyer employees or be entitled to any
fringe benefits otherwise provided or made available to Buyer's employees.
Moreover, Buyer will not account for any state, local, or federal income taxes,
FICA, employment taxes or other amounts normally withheld from compensation due
to the Transition Employees.

                                  ARTICLE III
                           RESPONSIBILITIES OF BUYER

                  In consideration for the services of the Transition Employees
to be provided pursuant to the terms of this Agreement by Sellers for Buyer,
Buyer shall pay to Sellers, and reimburse them for, the salaries (including
benefits) for the Transition Employees. Notwithstanding anything herein to the
contrary, in no event shall Buyer reimburse Sellers for any severance payments
or other severance compensation or benefits with respect to such Transition
Employees.

                  Payment by Buyer to Sellers of amounts described herein shall
be made within ten (10) business days of the end of each regular pay period,
provided that Sellers have delivered an invoice to Buyer relating thereto at
least five (5) business days prior to the expected date of reimbursement.
Sellers shall send all such statements of account and invoices via overnight
courier to Buyer at the following address: Baxter Healthcare Corporation, Attn.
Cynthia L. Collins, One Baxter Parkway, Deerfield, Illinois 60015. Sellers shall
keep appropriate books and records of account, in reasonable detail, of the
costs submitted to Buyer for reimbursement and shall provide to Buyer
appropriate supporting documentation for any material out-of-pocket and third
party expenses.

                                  ARTICLE IV
                                    PAYROLL

                  Sellers shall be responsible for maintaining payroll for
compensating Transition Employees, fulfilling all payroll tax and benefit
withholding and depositing obligations, and operating and administering all the
Seller Plans. During the Transition Period, Transition Employees shall be paid
through Sellers' payroll at the same rate such Transition Employees were paid as
of the beginning of the Transition Period. Sellers shall not change the salary
of any Transition Employee or pay a bonus to any Transition Employee during the
Transition Period, except as may be requested by Buyer in writing. Pursuant to
the terms of Article III, Buyer shall pay to Sellers or reimburse them for the
amount paid by Sellers with respect to Transition Employees through Sellers'
payroll system during the Transition Period (including payments for compensation
(whether or not deferred), any FICA taxes and employment taxes and unemployment
contributions paid by Sellers to Transition Employees).

meaning of HIPAA) to each Transition Employee (and his or her covered
dependents) for any HIPAA triggering event which occurs at any time (whether
before, during or after the Transition Period).

                  5.03. Vacation, Etc. During the Transition Period, each
                        -------------
Transition Employee's vacation days, sick leave and all other leaves of absence
shall be (or continue to be) administered in accordance with Sellers' policies
and programs applicable to Sellers' employees.

                  5.04. Workers' Compensation. Sellers shall remain responsible
                        ---------------------
and retain liability for, and shall pay, if and when due before or after the
Closing Date, the expense for all workers' compensation benefits (including
weekly benefits, medical and rehabilitation expenses, and any other expenses or
obligations) payable on account of any injuries, illnesses or other conditions
of Transition Employees that occur at any time (whether before, during or after
the Transition Period).

                                  ARTICLE VI

of Buyer setting forth in detail the assistance that is required, Sellers shall

at a place as the parties from time to time may mutually agree.

                  (b) Notwithstanding anything to the contrary contained herein,
Sellers shall make such persons providing transition services under this
Agreement who are employees of Sellers or any of their Affiliates (other than
the Transition Employees) available at such times and for such periods as are
reasonable to Sellers in light of the fact that these persons are responsible
for Sellers' and its Affiliate's operations.

permitted by law, the parties waive any provision of law which renders any such
provision prohibited or unenforceable in any respect.

                  7.09. No Third Party Beneficiaries. The terms and provisions
