         SECTION 4.05. Title to Properties and Assets, Liens, etc. Each of the
Issuer and its Subsidiaries has good and marketable title to its properties and
assets, and each of the Issuer and its Subsidiaries has good title to leasehold
estates, in each case subject to no Lien, other than (i) those resulting from
taxes which have not yet become delinquent, (ii) minor Liens which do not
materially detract from the value or present or intended use of the property
subject thereto or materially impair the operations of the Issuer or its
Subsidiaries, and (iii) those that have otherwise arisen in the ordinary course
of business. All facilities, machinery, equipment, fixtures, vehicles and other
properties owned, leased or used by the Issuer or its Subsidiaries are in good
operating condition and repair and are reasonably fit and usable for the
purposes for which they are being used.

         SECTION 4.06. Patents and Trademarks. The Issuer or its Subsidiaries
owns or possesses sufficient legal rights to all patents, trademarks, service
marks, trade names, copyrights, trade secrets, information and other
proprietary rights and processes (the "Intellectual Property Rights") necessary

known infringement of the rights of others. There are no outstanding options,
licenses or agreements of any kind relating to the foregoing, nor is the Issuer
or its Subsidiaries bound by or a party to any options, licenses or agreements
of any kind with respect to the patents, trademarks, service marks, trade
names, copyrights, trade secrets, licenses, information and other proprietary
rights and processes of any other Person other than such licenses or agreements
arising from the purchase of "off the shelf" or standard products. Except as
set forth in Schedule 4.06, neither the Issuer nor its Subsidiaries has
received any communications alleging that the Issuer or a Subsidiary has
violated or, by conducting its business as proposed, would violate any of the
patents, trademarks, service marks, trade names,

                                      11

<PAGE>


copyrights or trade secrets or other proprietary rights of any other Person.
Neither the Issuer nor any Subsidiary is aware that any of its employees is
obligated under any contract (including licenses, covenants or commitments of
any nature) or other agreement, or subject to any judgment, decree or order of
any court or administrative agency, that would interfere with their duties to
it or that would conflict with its business as proposed to be conducted.
Neither the execution nor delivery of this Agreement, nor the carrying on of
the Issuer's or any Subsidiary's business by the employees of the Issuer or any
Subsidiary, nor the conduct of the Issuer's or any Subsidiary's business as
proposed, will, to the Issuer's knowledge, conflict with or result in a breach
of the terms, conditions or provisions of, or constitute a default under, any
contract, covenant or instrument under which any such employee is now
obligated. The Issuer does not believe that it is or will be necessary to
utilize any inventions, trade secrets or proprietary information of any of its
employees made prior to their employment by the Issuer or any Subsidiary,
except for inventions, trade secrets or proprietary information that have been
assigned to the Issuer or such Subsidiary.

         SECTION 4.07. Employees. Except as set forth in Schedule 4.07, no
Employee of the Issuer or any Subsidiary has any agreement or contract, written
or verbal, regarding his or her employment. Except as set forth in Schedule
4.07, neither the Issuer nor any Subsidiary is a party to or bound by any
employment contract, deferred compensation arrangement, bonus plan, incentive
plan, profit sharing plan, retirement agreement or other employee compensation
plan or agreement. To the best of the Issuer's knowledge, no employee of the
Issuer or any Subsidiary, nor any consultant with whom the Issuer or any
Subsidiary has contracted, is in violation of any term of any employment
contract, proprietary information agreement or any other agreement relating to
the right of any such individual to be employed by, or to contract with, the
Issuer or any Subsidiary because of the nature of the business to be conducted
by the Issuer or any Subsidiary, and, to the best of Issuer's knowledge, the
continued employment by the Issuer or any Subsidiary of its present employees,
and the performance of the Issuer's or any Subsidiary's contracts with its
independent contractors, will not result in any such violation. Neither the
Issuer nor any Subsidiary has received any notice alleging that any such
violation has occurred. Other than pursuant to certain of the Ancillary
Agreements, no employee of the Issuer or any Subsidiary has been granted the
right to continued employment by the Issuer or any Subsidiary or to any
material compensation following termination of employment with the Issuer or
any Subsidiary. Neither the Issuer nor any Subsidiary is aware that any officer
or key employee, or that any group of key employees, intends to terminate their
employment with the Issuer or any Subsidiary. Neither the Issuer nor any
Subsidiary has a present intention to terminate the employment of any officer,
key employee or group of key employees.

         SECTION 4.08. Environmental and Safety Laws. To the best of the
Issuer's knowledge, neither the Issuer nor its Subsidiaries is in violation of
any applicable statute, law, rule or regulation relating to the environment or
occupational health and safety, and, to the best of its knowledge, no material
expenditures are or will be required in order to comply with any such existing
statute, law or regulation.

                                  TERMINATION

         SECTION 7.01. Grounds for Termination. This Agreement may be
terminated at any time prior to any Closing:

                   (i) by either the Issuer or (solely with respect to the
         rights and obligations of such Investor) any Investor if there shall
         be any law or regulation that makes consummation of the transactions
         contemplated hereby illegal or otherwise prohibited with respect to
         the Issuer or such Investor or if consummation of the transactions
         contemplated hereby would violate any nonappealable final order,
         decree or judgment of any court or governmental body having competent
         jurisdiction with respect to the Issuer or such Investor;

                  (ii) by MSCP (solely with respect to the  obligations of MSCP
         and its Affiliates  hereunder) on December 18, 2004; or

                 (iii) by MSCP or any Designated Holder (in either case, solely
         with respect to the obligations of such Investor) pursuant to the
         terms of Section 9.10 hereof.

         The party desiring to terminate this Agreement shall give notice of
such termination to the other parties.

         SECTION 7.02. Effect of Termination. If this Agreement is terminated
as permitted by Section 7.01, termination shall be without liability of any
party (or any stockholder, director, officer, employee, partner, agent,
consultant or representative of such party) to any other party to this
Agreement, other than any such liability (including with respect to
representations and warranties) that may have arisen in connection with any
Closing that has been consummated prior to such termination; provided that if
such termination shall result from the willful failure of any party to fulfill
a condition to the performance of the obligations of any other party, failure
to perform a covenant of this Agreement or breach by any party hereto of any
representation or warranty or agreement contained herein, such party shall be
fully liable for any and all damages incurred or suffered by any other party as
a result of such failure or breach. The provisions of Article 8 shall survive
any termination hereof pursuant to Section 7.01.



                                   ARTICLE 8
                                COVENANTS, ETC.

         SECTION 8.01. Preferred Stock Election. On June 1, 1998, MSCI elected,
pursuant to Section 5(b) of the Certificate of Designation relating to the
Series A Preferred Stock of the Issuer, to exchange at the First Closing each
of its shares of such Series A Preferred Stock, in lieu of

                                      17
<PAGE>

redemption, for 587 Common Shares. The Issuer hereby makes, as of June 1, 1998,
for the benefit of MSCI, the representations and warranties set forth in
Articles 3 and 4 as of the date such shares were issued to MSCI, it being
understood that such Common Shares shall be deemed "Common Shares", and MSCI
shall be deemed an "Investor" for such purpose.

         SECTION 8.02. Certain Financings. Following the purchase by the MSCP
Funds of all of the Common Shares listed on Schedules 2.01(b) and 2.01(c)
hereto to be purchased by them, but prior to the IPO (as defined in the
Shareholders Agreement), the Issuer shall, and shall cause each Subsidiary to,
offer MSCP and its Affiliates the exclusive opportunity to provide equity and
equity-linked financing to the Issuer or such Subsidiary, respectively, prior
to initiating discussions with any other Person (other than (i) the owner of a
hospital, hospital system or foundation solely as consideration for the
acquisition by the Issuer of (x) assets owned by such hospital, hospital system
or hospital foundation or (y) the capital stock of, or other equity interests
in, a Person owning the assets of such hospital, hospital system or hospital
foundation, (ii) issuances of capital stock or other equity securities of a
wholly owned Subsidiary of the Issuer to the Issuer or another wholly owned
Subsidiary of the Issuer, or (iii) issuances of capital stock or other equity
securities of any Subsidiary of the Issuer to physicians or other healthcare
providers (or any respective Affiliates thereof) in connection with bona fide
joint ventures with such Person) regarding obtaining such financing. The Issuer
and MSCP and/or its designated Affiliate(s) shall negotiate the terms of the
proposed financing, including arrangements (referred to herein as the "Carried
Interest Arrangements") providing for the Management Investors' opportunity to
receive a portion of the gains that would otherwise be realized by MSCP and/by
its designated Affiliate(s) (and by any other investor whom MSCP elects to
permit to participate in such financing, if applicable) on such proposed
financing, in good faith for a period of at least 60 days. If the Issuer and
MSCP or such Affiliate(s) cannot negotiate such financing on a mutually
acceptable basis during such 60-day period, the Issuer may initiate discussions
with and obtain such financing from a third party upon terms and subject to
conditions that (i) are at least as favorable to the Issuer as those discussed
with MSCP or such Affiliate(s) and (ii) contemplate carried interest
arrangements for the Management Investors that are more favorable to the
Management Investors than the Carried Interest Arrangements proposed by MSCP or
such Affiliate during the final round of such negotiations. If the Issuer shall
not have obtained such proposed financing within 180 days after the expiration
of such 60-day period, then the Issuer shall again comply with the procedures
set forth in this Section with respect to any proposed equity or equity-linked
financing.




                                   ARTICLE 9
                                 MISCELLANEOUS

         SECTION 9.01. Notices. All notices, requests and other communications
to any party hereunder shall be in writing (including telecopier) and shall be
deemed to have been duly given or made if sent by telecopy, delivered
personally or sent by registered or certified mail (postage prepaid, return
receipt requested) to such party at its address or telecopier number set forth
on the signature

                                      18
<PAGE>

pages hereof, or such other address or telecopier number as
such party may hereinafter specify for the purpose to the party giving such
notice provided notices to MSCP and its Affiliates must also be sent to the
following counsel for MSCP and its Affiliates: Davis Polk & Wardwell, 450
Lexington Avenue, New York, NY 10017, phone (212) 450-4000, fax (212)450-4800,
Attention: John Bick, Esq. All such notices, requests and other communications
shall be deemed received on the date of receipt by the recipient thereof if
received prior to 5:00 p.m. in the place of receipt and such day is a Business
Day in the place of receipt. Otherwise, any such notice, request or
communication shall be deemed not to have been received until the next
succeeding Business Day in the place of receipt.

         SECTION 9.02. No Waivers; Amendments. (a) No failure or delay on the
part of any party in exercising any right, power or privilege hereunder shall
operate as a waiver thereof, nor shall any single or partial exercise thereof
preclude any other or further exercise thereof or the exercise of any other
right, power or privilege. The rights and remedies herein provided shall be
cumulative and not exclusive of any rights or remedies provided by law.

           (b) Any provision of this Agreement may be amended or waived if, but
only if, such amendment or waiver is in writing and is signed, in the case of
an amendment, by the Issuer, MSCP and Investors (other than MSCP, its
Affiliates and their Permitted Transferees) owning at least 50% of the Common
Shares then owned by such Investors or, in the case of a waiver, by the party
or parties against whom the waiver is to be effective.

         SECTION 9.03. Expenses; Documentary Taxes. Except as otherwise
provided in the Ancillary Agreements, each party hereto shall bear its own fees
and expenses incurred in connection with the preparation of this Agreement and
each Ancillary Agreement and the consummation of the transactions contemplated
hereby and thereby; provided that the Issuer shall pay any and all stamp,
transfer and other similar taxes payable or determined to be payable in
connection with the execution and delivery of this Agreement or any of the
Common Shares.

         SECTION 9.04. Several Obligations. The obligations of the Investors
hereunder are several. Neither the failure of any Investor to carry out its
obligations hereunder nor of this Agreement to be duly authorized, executed and
delivered by any Investor shall relieve any other Investor of its obligations
hereunder (or affect the rights hereunder of such other Investor). No Investor
shall be responsible for the obligations of, or any action taken or omitted by,
any other Investor hereunder.

         SECTION 9.05. Successors, Assigns, Transferees. The provisions of this
Agreement shall be binding upon and accrue to the benefit of the parties hereto
and their respective successors, heirs, executors and administrators.
Notwithstanding the foregoing, neither this Agreement nor any right, remedy,
obligation or liability arising hereunder or by reason hereof shall be
assignable by the Issuer or any Investor without the consent of the other
parties hereto. Nothing in this Agreement, expressed or implied, is intended to
confer on any Person other than the parties hereto, and their respective
successors and permitted assigns, any rights, remedies, obligations or
liabilities under or by reason of this Agreement.

         SECTION 9.06. Counterparts. This Agreement may be executed in any
number of counterparts each of which shall be an original with the same effect
as if the signatures thereto and

                                      19

<PAGE>

hereto were upon the same instrument. No provision of this Agreement is
intended to confer upon any Person other than the parties hereto any rights or
remedies hereunder.

         SECTION 9.07. Entire Agreement. The Transaction Agreements (as defined
in the Shareholders Agreement), constitute the entire agreement and
understanding of the parties hereto and thereto in respect of the subject
matter contained herein and therein, and there are no restrictions, promises,
representations, warranties, covenants, or undertakings with respect to the
subject matter hereof or thereof, other than those expressly set forth or
referred to herein or therein. This Agreement, the Ancillary Agreements and the
other agreements referred to herein and therein supersede all prior agreements
and understandings between the parties hereto and thereto with respect to the
subject matter hereof and thereof, including the letter of intent dated as of
April 2, 1998 among the Issuer, the Executive Managers and MSCI.

         SECTION 9.08. Reasonable Best Efforts. Subject to the terms and
conditions of this Agreement, each party will use its reasonable best efforts
to take, or to cause to be taken, all actions and to do, or cause to be done,
all things necessary, proper and advisable under applicable laws and
regulations to consummate the transactions contemplated by this Agreement.

         SECTION 9.09. Applicable Law; Submission to Jurisdiction. This
Agreement shall be construed in accordance with and governed by the laws of the
State of Delaware, without regard to the conflicts of law rules of such state.
Each of the parties hereto hereby consents to the exclusive jurisdiction of the
United States District Court for the District of Delaware and the Chancery
Court of the State of Delaware (and of the appropriate appellate courts
therefrom) over any suit, action or proceeding arising out of or relating to
this Agreement. Each party hereto irrevocably waives, to the fullest extent
permitted by law, any objection which it may now or hereafter have to the
laying of venue in any such court or that any such proceeding which is brought
in accordance with this Section has been brought in an inconvenient forum.
Subject to applicable law, process in any such proceeding may be served on any
party anywhere in the world, whether within or without the jurisdiction of any
such court. Without limiting the foregoing and subject to applicable law, each
party agrees that service of process on such party as provided in Section 9.01
shall be deemed effective service of process on such party. Nothing herein
shall affect the right of any party to serve legal process in any other manner
permitted by law or at equity or to enforce in any lawful manner a judgment
obtained in one jurisdiction in any other jurisdiction. WITH RESPECT TO A
PROCEEDING IN ANY SUCH COURT, EACH OF THE PARTIES IRREVOCABLY WAIVES AND
RELEASES TO THE OTHER ITS RIGHT TO A TRIAL BY JURY, AND AGREES THAT IT WILL NOT
SEEK A TRIAL BY JURY IN ANY SUCH PROCEEDING.

         SECTION 9.10. Disclosure Schedules. After the Fourth Closing, the
Issuer may revise the Schedules to Article 3 of this Agreement by delivering
revised Schedules to MSCP and each Designated Holder who is a Purchasing
Investor not less than 15 Business Days prior to the date of each subsequent
Closing. If such Schedules are not revised in connection with a subsequent
Closing, then the Issuer shall deliver a notice to MSCP and each Designated
Holder who is a Purchasing Investor (at least 10 days prior to each such
Closing) that no such revised Schedules are being delivered by the Issuer in
connection with such subsequent Closing. MSCP and each Designated Holder shall
have the right to review the revised Schedules to Article 3 hereof for a period
of 10 Business Days after receipt thereof. At any time within such 10-Business
Day time period, MSCP

                                      20
<PAGE>

and each Designated Holder shall have the right to terminate this Agreement
(but only as to such Investor) by delivery of a notice to the Issuer if MSCP or
such Designated Holder, as applicable, reasonably believes that the revised
information would reasonably be likely to result in a Material Adverse Effect.
This notice, if given, shall specify the information forming the basis for the
decision to terminate. The Issuer shall have 5 Business Days after receipt of
such notice to review with each such Investor the information forming the basis
for the decision to terminate and to attempt to agree on corrective measures,
if any. If the parties cannot agree on corrective measures within such
5-Business Day period, then this Agreement shall terminate with respect to such
Investor. If this Agreement is not terminated by MSCP or a Designated Holder as
permitted by this Section and Section 7.01(iii), such Investor shall be deemed
to have accepted such revisions, and the Schedules to Article 3 hereof that are
attached to this Agreement as of June 1, 1998 shall be deemed to be superseded
by the revised Schedules to Article 3 hereof.

         SECTION 9.11. Effectiveness. This Amended and Restated Subscription
Agreement shall become effective when both of the following have occurred: (1)
this instrument has been executed by the Issuer, Morgan Stanley Capital
Partners III, L.P. and Investors (other than Morgan Stanley Capital Partners
III, L.P., its Affiliates and their Permitted Transferees) owning at least 50%
of the Common Shares then owned by such Investors and (2) the Shareholders
Agreement has been executed by Investors owning at least 75% of the number of
outstanding Common Shares owned by all Investors as of the date hereof.
