                      AMENDMENT NO. 2 TO POOLING AGREEMENT

        AMENDMENT NO. 2, dated as of April 17, 1997 (this "Agreement"), to
Pooling Agreement dated as of November 16, 1993 (as amended, supplemented or
otherwise modified from time to time, the "Pooling Agreement"), among UHS
Receivables Corp., a Delaware corporation (together with its successors and
assigns, "Finco"), Sheffield Receivables Corporation, a Delaware corporation
(together with its successors and assigns, "Sheffield"), and First Bank National
Association, a national banking association (successor in interest to
Continental Bank, National Association), as trustee (in such capacity, together
with its successors and assigns, the "Trustee").

                              W I T N E S S E T H :

        WHEREAS, pursuant to the Sale and Servicing Agreements (capitalized
terms used without definition in the recitals have the meanings assigned to them
in the Pooling Agreement, including without limitation definitions incorporated
by reference from the Definitions List) the Hospitals have agreed to sell, and
Finco has agreed to purchase, the Receivables and other Transferred Property;

        WHEREAS, Finco has assigned and transferred to the Trustee on behalf of
the Trust and pursuant to the terms and conditions set forth in the Pooling
Agreement all of its right, title and interest in, to and under the Receivables
and other Finco Transferred Property;

        WHEREAS, Finco, Sheffield and the Trustee wish to amend the Pooling
Agreement to provide for Finco to transfer to the Trustee Receivables from
additional Hospitals entering into Sale and Servicing Agreements as of the date
hereof, to reflect their agreement not to create Trade Receivables Investment
Participation (TRIPS) as originally contemplated, and to make certain other
changes;

        NOW THEREFORE, the parties hereto agree as follows:

        Section 1.  Additional Hospitals.  The Pooling Agreement is hereby
amended to provide that the receivables and other property of the additional
hospitals entering Sale and Servicing Agreements on or after the date hereof
shall be transferred to the Trustee pursuant to the Pooling Agreement; such
additional hospitals shall be deemed "Hospitals" for all purposes under the
Pooling Agreement; and all references in the Pooling Agreement to "Receivables",
"Transferred Property" and other terms shall be deemed to include the analogous
terms relating to such hospitals.

        Section 2.  Procedures for Adding Hospitals.  Additional hospitals may
be added after written notice from Finco to Sheffield and the Trustee upon
receipt by Finco and the Trustee of written consent by Sheffield to the addition
of such hospital and the execution and delivery of a Sale and Servicing
Agreement by such hospital and Finco.

   2
        Section 3. Termination of TRIPS Provisions.  The parties have agreed
not to create the TRIPS Participations contemplated at the time the Pooling
Agreement was executed. Accordingly, the parties hereby agree that:

        (a)   the Trustee shall have no obligation to maintain a TRIPS Register
     or provide notices to any TRIPS Holder, and the Pooling Agreement is hereby
     amended to delete the requirement that the Trustee maintain a TRIPS
     Register or provide notices to any TRIPS Holder; and

        (b)   the Trustee shall have no obligation to maintain the TRIPS Payment
     Account, the TRIPS Sub-account and the TRIPS Interest Sub-account, and the
     Pooling Agreement is hereby amended to delete the requirement that the
     Trustee maintain such accounts.

        Section 4.  Other Amendments.

        (a)   The Pooling Agreement is hereby amended to replace the definitions
     of "Concentration Limit", "Offset Reserves", "Maximum Aggregate Capital",
     "Maximum Sheffield Capital" and "Preferred Insurer/HMO/PPO" incorporated by
     reference from the Definitions List with the definitions set forth on
     Exhibit A to this Amendment.

        (b)   Sections 2.13(b) of the Pooling Agreement is hereby amended to
     increase the maximum Aggregate Capital from $85,000,000 to $100,000,000.

        (c)   The Trustee shall have no obligation to maintain the Sheffield
     Sub-account.  All reference in the Pooling Agreement to such account shall
     be deemed to be references to the Collateral Account.

        Section 5.  Effect of Amendment.  The Pooling Agreement as modified by
this Amendment shall remain in full force and effect, and all references in the
Pooling Agreement to "this Agreement" shall mean the Pooling Agreement as
amended hereby unless the meaning requires otherwise.

        Section 6.  Counterparts.  This Amendment may be executed in any number
of copies, and by the different parties hereto on the same or separate
counterparts, each of which shall be deemed to be an original instrument.

        Section 7.  GOVERNING LAW.  THIS AMENDMENT SHALL BE GOVERNED BY, AND
CONSTRUED AND INTERPRETED IN ACCORDANCE WITH, THE INTERNAL LAW OF THE STATE OF
NEW YORK WITHOUT REFERENCE TO CONFLICTS OF LAW RULES OF THE STATE OF NEW YORK.

                                      -2-
