<PAGE>   2
                  NOW, THEREFORE, in consideration of the premises and covenants
set forth herein and other good and valuable consideration, the receipt and
sufficiency of which are hereby acknowledged, PHC and Holdco agree as follows:

                  1. Transition Services. During the term of this Agreement as
set forth in Section 5 below (the "Transition Period"), PHC shall provide, or
cause its Affiliates to provide, to Holdco and its subsidiaries the services set
forth on such Annex A (the "Services"), in the manner, at the locations and at a
relative level of service consistent with that provided by PHC or its Affiliates
to or for the benefit of the Business immediately prior to the date hereof. The
Services shall be provided from PHC's data processing center (the "Data Center")
in Houston, Texas using PHC's computer processing equipment at such site, with
the exception of the CompuLab Clinical Lab System which is operated at the
Paracelsus Davis Hospital, Inc. facility. Holdco or its Subsidiaries operating
the Business shall be responsible for (i) coding and transmitting the data (the
"Facilities Data") to be processed hereunder to the Data Center, (ii)
supervising the conversion of the Facilities Data, including financial data,
into a form that can be processed by PHC, (iii) determining whether the
Facilities have complied with applicable accounting practices, (iv) determining
whether the Facilities have complied with applicable state and federal
regulations governing financial reporting obligations; (v) verifying the
accounting of data generated by the Facilities or by PHC from other data
generated by the Facilities; (vi) maintaining prudent internal controls of
reports and data generated by the Facilities and (vii) maintaining all equipment
and all communication lines at the Facilities to the extent reasonably necessary
in connection with providing the Services. The Services used by Holdco and its
subsidiaries shall be provided, and Holdco shall pay for such Services (i) an
amount equal to actual costs to PHC (including third-party out-of-pocket costs
and PHC's reasonable internal overhead and administrative costs) of providing
such Services plus two percent (2%) (the "Service Fee") and (ii) those charges
set forth in Annex B hereto (the "Charges").

                  PHC will provide to Holdco and its subsidiaries operating the
Business, for the term of this Agreement, and to the extent necessary to utilize
the Services, a non-transferable and non-exclusive right to use the computer
software systems (the "Software") set forth in Annex A to the extent permitted
by and in accordance with the terms and conditions of the applicable Service
Agreements.

                  Holdco and its subsidiaries operating the Business shall have
no rights in the Software not expressly granted hereby, including, but not
limited to any right to: alter the Software; create derivative works; distribute
or sublicense the Software to third parties; incorporate additional software
into the Software at the operating system level; incorporate the Software into
any publicly available database; reproduce the Software; or use the software for
any purpose other than as specified by this Agreement.

                  From time to time PHC may, but is not obligated to, update the
Software at no additional charge to Holdco. In such event, Holdco will
discontinue use of the





                                        2
<PAGE>   3
then-current version of the Software within 60 days after its receipt of the
updated Software and substitute the updated version of such Software in
accordance with any installation guidelines provided by PHC.

                  2. Billing and Payment. At the end of each calendar month
during the Transition Period, PHC shall submit to Holdco a bill or invoice
setting forth the Service Fees and Charges for Services provided by PHC or its
Affiliates during the immediately preceding month. Holdco shall pay all bills
and invoices that it receives from PHC or its Affiliates for the Services
provided under or pursuant to this Agreement within thirty (30) calendar days of
receipt of such bill or invoice. All payments will be made by wire transfer or
by check in accordance with the instructions provided in writing by PHC.

                  3. General Intent. PHC shall use its reasonable best efforts
to provide the Services it is to provide that are set forth on Annex A attached
hereto and such other transition services and assistance as the parties may
otherwise agree (with respect to such additional services, at a cost and for
such period as is mutually agreed). Holdco agrees to use its reasonable best
efforts to end its need to use such assistance as soon as reasonably possible
and (unless the parties otherwise agree) in all events to end such need with
respect to each Service specified in Annex A attached hereto not later than the
first anniversary of the date hereof; provided, however, that if PHC is not
permitted, by the terms of its Agreements with third parties relating to the
Services, to provide any of the Services hereunder for the entire Term, then
such Service or Services shall only be provided by PHC to the extent, and for
the period of time permitted by, such Agreement.

                  4. Validity of Documents. The parties hereto shall be entitled
to rely upon the genuineness, validity or truthfulness of any document,
instrument or other writing presented in connection with this Agreement unless
such document, instrument or other writing appears on its face to be fraudulent,
false or forged.

                  5. Term of Agreement. The term of this Agreement (the "Term")
shall commence on the date hereof and shall continue (unless sooner terminated
pursuant to the terms of Section 6 hereof) for a period of one year or, with
respect to any of the Services, such shorter period as may be permitted under
the terms of third-party agreements relating to such Services. It is understood
that Services provided in accordance with the Keane Agreement may not exceed a
period of six months under the terms of the Keane Agreement unless otherwise
agreed upon by Keane.

                  6. Partial Termination. The provision of one or more of the
Services provided by PHC and/or its Affiliates hereunder may be terminated by
Holdco earlier than the first anniversary of the date hereof, on not less than
sixty (60) days' prior written notice to PHC. Such termination shall be final as
of such sixtieth day or other later date specified in the applicable notices
only with respect to the Service(s) so terminated and the remainder of the
Services shall continue to be provided in accordance



                                       3
<PAGE>   4
with the terms of this Agreement, including Annex A hereto, for the remainder of
the Term.

                  7. Assignment. This Agreement shall not be assignable or
otherwise transferable by any party hereto, other than to its affiliates,
without the prior written consent of the other party hereto provided that Holdco
shall be permitted to assign its rights hereunder to the financing sources of
Holdco with respect to the financing of the transactions contemplated by the
Recapitalization Agreement and provided that PHC shall be permitted to assign
its rights and obligations hereunder to any person or entity that acquires
substantially all the business and assets of PHC, whether by merger,
consolidation, sale of stock or assets or otherwise.

                  8. Confidentiality. Each party shall, and shall cause each of
its Affiliates and each of their officers, directors and employees to, hold all
confidential or proprietary information relating to (i) the Services or (ii) the
business of the other party disclosed to it by reason of this Agreement
confidential and will not disclose any of such information to any party unless
legally compelled to disclose such information; provided, however, that to the
extent that any of them may become so legally compelled they may only disclose
such information if they shall first have used reasonable efforts, to have
afforded the other party the opportunity to obtain an appropriate protective
order or other satisfactory assurance of confidential treatment for the
information required to be so disclosed.

                  9. Limitation of Liability. PHC shall not be liable to Holdco
or any third party (including specifically affiliates or employees of Holdco)
and Holdco shall not be liable to PHC or any third party (including specifically
affiliates or employees of PHC) for any special, punitive, consequential,
incidental or exemplary damages (including lost or anticipated revenues or
profits relating to the same) arising from any claim relating to this Agreement
or any of the services provided hereunder, whether such claim is based on
warranty, contract, tort (including negligence or strict liability) or
otherwise, even if an authorized representative of PHC or Holdco, as applicable,
is advised of the possibility or likelihood of the same. In addition, PHC shall
not be liable to Holdco or any third party (including specifically employees of
Holdco) for any damages arising from any claim relating to this Agreement or any
of the Services provided hereunder or required to be provided hereunder, except
to the extent that such damages are caused by the willful misconduct or gross
negligence of PHC or its Affiliates, as applicable.

                  10. Indemnification.

                           (a) To the fullest extent permitted by law, from and
after the date hereof Holdco shall indemnify and hold PHC harmless, including

misconduct.

after the date hereof PHC shall indemnify and hold Holdco harmless, including

from, or related to this Agreement, the Services provided hereunder, or its
actions in relation thereto, including Damages alleged or caused to third
