from cost reports for periods through the Closing Date;

                  (e)      all refunds relating to any federal, state, local
or foreign taxes paid by, or on behalf or for the benefit of a Party or, to the
extent they relate to the period prior to the Closing Date, the Facilities,
whether received prior to or after the Closing Date;

                  (i)      any other assets expressly designated in Schedule
1.2(i) to this Agreement as Excluded Assets.

         1.3      Contract Assignments.

                  1.3.1  Assignment of Interest in Contracts.  Except for
intercompany and non-physician employment contracts, on the Closing Date and
upon and subject to the terms and conditions set forth in this Agreement, the
Parties shall transfer or cause to be transferred and assign or cause to be
assigned to Newco UHS-1 and Newco Q-1, as the case may be, and Newco UHS-1 and
Newco Q-1 shall assume and perform all of the Parties' interest in (including
all rights, benefits and obligations) all commitments, contracts, leases,
licenses, agreements and understandings, and all outstanding offers or
solicitations to enter into any of the foregoing, including those described on
Schedule 1.3.1 hereto (the "Assumed Contracts").

                  1.3.2  Consents to Assignments.  Notwithstanding anything in 
this Agreement to the contrary, this Agreement shall not constitute an agreement
to assign or transfer any of the Assumed Contracts or part thereof or right or
benefit arising thereunder or resulting therefrom if an attempted assignment or
transfer thereof, without the consent of a third party thereto, would constitute
a breach thereof or in any way affect the rights of the Company following the
Merger. If such consent is not obtained, or if an attempted assignment thereof
would be ineffective or would affect the rights of the Company following the
Merger, so that the Company would not in fact receive all such rights, Valley or
Desert Springs, as the case may be, (i) shall cooperate with the Company in its
request in endeavoring to obtain such consent promptly at no cost to the
Company, and (ii) if any such consent is unobtainable, shall cooperate with the
Company in any reasonable arrangement (the "Assignment Substitute") designed to
provide the Company the benefits under any such Assumed Contract or part thereof
or any right or benefit arising thereunder or resulting therefrom, including
enforcement for the benefit of the Company of any and all rights of Valley or
Desert Springs against a third party arising out of the breach or cancellation
by such third party or otherwise. Valley and Desert Springs shall, to the extent
necessary, perform under the Assignment Substitute without a fee to the Company
except the consideration being tendered hereunder.

         1.4      Instruments of Conveyance.

                  On the Closing Date, Valley shall deliver to Newco UHS-1 and 
Desert Springs shall deliver to Newco Q-1 such deeds (in the case of the real
property and the improvements thereon described in Schedules 2.10 hereto, a
special warranty deed or the equivalent thereof in use in accordance with local
practice), bills of sale, endorsements, assignments and other good and
sufficient instruments of conveyance and assignment, including the Schwartz
Sublease as shall be effective to vest in Newco UHS-1 and Newco Q-1, as the
case may be, all of the Parties' respective right, title and interest in and to
the Facilities Assets, free and clear of all Liens except for the Permitted
Encumbrances. Simultaneously with such delivery, the Parties will take all
reasonable additional steps as may be necessary to put the Company, following
the Merger, in possession of the Facilities Assets. The Parties shall pay all
transfer costs, title insurance fees, recording fees and transfer or stamp taxes
or similar charges payable by each of them respectively by reason of the
contribution, conveyance, assignment, transfer and delivery hereunder of the
Facilities Assets.

         1.5      Consideration; Working Capital Shortage/Overage.

                  1.5.1  In consideration of the transfer and conveyance of the 
Facilities Assets and the Merger, on the Closing Date the Parties acknowledge
and agree that the Company shall issue membership interests in the Company as
follows: (i) the Company shall issue a 72.5% membership interest in the Company
to Valley and (ii) the Company shall issue a 27.5% membership interest in the
Company to Desert Springs.

                  1.5.2  Within 45 days after the Closing Date, the Parties will
determine the Working Capital Shortage to be paid to the Company by either
Valley or Desert Springs or the Working Capital Overage to be retained by either
Valley or Desert Springs. The Working Capital Shortage or Overage will be the
amount necessary to make the Working Capital contributed by each Party equal
that Party's percentage membership interest in the Company. For example, if
Valley contributed $7,250,000 in Working Capital to the Company on the Closing
Date and Desert Springs contributed $2,550,000 in Working Capital to the Company
on the Closing Date, then the Working Capital Shortage would be $200,000 to be
paid to the Company by Desert Springs or the


                                       7
<PAGE>   11

Working Capital Overage would be $527,272.72 which would be retained by Valley
rather than contributed. The Working Capital Shortage shall be calculated and
used unless Valley and Desert Springs shall agree to calculate and use the
Working Capital Overage. For the sole purpose of determining the Working Capital
Shortage or Overage, Working Capital will be defined as the sum of the following
items that have been contributed to or assumed by the Company, all valued in
accordance with generally accepted accounting principles, consistently applied
(unless otherwise specified):

                  (a)      patient accounts receivable, net of allowances for
contractual adjustments and discounts and bad debts (computed on a basis
consistent with historical practice) except that the allowance for bad debts
will be equal to the amount of patient accounts receivable older than one
hundred seventy-nine (179) days from discharge for inpatients or date of
services for outpatients;

                  (b)      plus inventories, based on a physical count at the
Closing Date, priced at latest invoice cost, and including only those items and
areas that have historically been counted;

                  (c)      plus prepaid expenses, but only to the extent that
they are usable by the Company;

                  (d)      plus other receivables, net of allowances for
uncollectibles;

                  (e)      less trade accounts payable;

                  (f)      less accrued compensation and related taxes thereon 
and related liabilities, including accrued vacation, sick leave payable in cash
for reasons other than actual absence, paid time off, or the like;

                  (g)      less other accrued liabilities and expenses;

                  (h)      less the present value (computed using the prime
rate as the discount factor) of remaining payments due under any capitalized
lease included in the Assumed Contracts; and

                  (i)      less any other liabilities assumed by the Company
to the extent such liabilities are to be included on the balance sheet under
generally accepted accounting principles.

<PAGE>   12


                  Each of the Parties will work together in good faith to
agree on adjustments to and the amount of Working Capital Shortage. No later
than 45 days after the Closing Date, the Parties hereto shall prepare the "Final
Closing Statement" reflecting the items listed above determined as set forth
above. Any payment due on the Final Closing Statement shall be payable in cash,
on or before the tenth day following the day the Final Closing Statement is
agreed upon. If the Parties are unable to agree on the Final Closing Statement
within the 45 day period, they shall appoint Coopers & Lybrand, a firm of
independent certified public accountants of recognized national standing (the
"Accountants"), to make such determination, which determination shall be final
and binding on the Parties hereto for the purposes of this Agreement, and Valley
and Desert Springs shall each pay one-half of the fee. Each Party represents
that the Accountants are not its auditor.

         1.6      Liabilities Assumed.  In further consideration for the
contribution of the Facilities Assets, on and as of the Closing Date, subject to
the exclusion of liabilities described in Section 1.7 below, the Parties
acknowledge and agree that Newco UHS-1, Newco Q-1 and the Company, following the
Merger, shall assume and agree to pay, perform and discharge the following
liabilities (collectively, the "Assumed Liabilities"):

                  (a)      all current liabilities of the Parties (except for
the current portion of long term debt, accrued interest, pension plan
liabilities, employer benefit plan liabilities, intercompany liabilities and
self-insurance costs);

                  (b)      all obligations under the Assumed Contracts and
under Section 4.6 hereof; and

                  (c)      such other liabilities of the Parties which the
Company agrees in writing at or prior to the Closing Date that the Company will
assume, which liabilities are listed on Schedule 1.6(c).

         1.7      Liabilities Not Assumed.  Newco UHS-1, Newco Q-1 and
the Company, following the Merger, shall assume only those liabilities and
obligations specified in Section 1.6 above. Without limiting the generality of
the foregoing sentence, neither Newco UHS-1, Newco Q-1 nor the Company shall
assume and each Party shall retain and be responsible for the following
obligations and liabilities to the extent they relate to such


                                       9
<PAGE>   13

Party (except to the extent reflected in the calculation of the Working Capital
Shortage) (each reference in this Section 1.7 to a Party shall include such
Party and its affiliates):

                  (a)      any and all obligations for the payment of any long

claims relating to periods prior to the Closing Date;

or obligations for any and all workers' compensation, health, disability or
other benefits due to or for the benefit of any employees of a Party (or their
covered dependents);

                  (g)      liabilities arising out of or in connection with
claims, litigations or proceedings described in Section 2.16, and claims,
litigations or proceedings (whether instituted prior to or after the Closing
Date) for acts or omissions which allegedly occurred prior to or at the Closing
Date;

provision of goods and services, tax sharing arrangements, payment arrangements,
intercompany charges or balances, or the like;

                  (l)      except for Assumed Liabilities, any and all actual

acts or omissions of either of the Parties (actual or alleged) prior to the
Closing Date;

                  (m)      all liabilities arising out of or in connection
with the existence of Materials of Environmental Concern (as hereinafter
defined) upon, about, beneath or migrating to or from any of the Real Property
on or before the Closing Date or the existence on or before the Closing Date of
any Environmental Claim (as hereinafter defined) or any violation of any
Environmental Laws (as hereinafter defined) pertaining to such Real Property or
the operation of the Facilities by a Party or any other business operated
therefrom;

                  (n)      any liability which allegedly occurred out of any

                                       11

                  With respect to Subsection 1.7(m) above, for a period of five
(5) years from and after the Closing Date, in the event that it cannot be proven
that the event giving rise to a Subsection 1.7(m) liability occurred after the
Closing Date then it shall be presumed to have occurred on or before the Closing
Date and the Parties can rebut this presumption with a Phase I environmental
study. From and after five (5) years following the Closing Date, the presumption
shall shift and thereafter all events giving rise to a Subsection 1.7(m)
liability shall be presumed to have occurred from and after the Closing Date.

         1.8      Closing.  The closing of the transactions provided herein will
be accomplished by means of overnight courier delivery and facsimile

contribution of the Facilities Assets which shall be as of 11:59 p.m. Pacific
Time on January 31, 1998, and consummation of the Merger, the closing shall be
deemed to be effective and shall be deemed to have occurred as of 12:01 a.m.
Pacific Time on February 1, 1998 which is as of the date and time specified in
the Agreement of Merger. Such date and time of effectiveness of the Merger is
herein referred to as the "Closing Date".

                                       12
<PAGE>   16

which property owned, leased or operated by it or the nature of the business
conducted by it makes such qualification necessary and where the failure to so
qualify would have a material adverse effect on it. No Party is in default with

charge, pledge, security interest or other encumbrance upon any part of the
property of such Party or Newco UHS-1 or Newco Q-1 pursuant to any provision of,
any order, judgment, arbitration award, injunction, decree, indenture, mortgage,
lease, license, lien, or other agreement or instrument to which such Party or

                           6.1.2    Except as caused solely by any change in
the relevant market conditions and prospects, for which the other Party shall
assume all risk, there shall have been no material adverse change since the date
of the Balance Sheets in the financial condition, business or affairs of each
Party; and each Party shall not have suffered any material loss (whether or not
insured) by reason of physical damage caused by fire, earthquake, accident or
other calamity which substantially affects the value of its assets, properties
or business the insurance proceeds related to which are not, in the reasonable
opinion of the other Party, adequate to repair such damage and compensate for
any lost business related thereto. Each Party shall have received a certificate
of the other Party dated the Closing Date that the statements set forth in this
Section 6.1.2 are true and correct.

                           6.1.3    Each Party shall have delivered to the other

Bylaws of such Party attached to such certificate are complete and correct and
in effect as of the date of such certification.

                           6.1.5    Each Party shall have received from counsel
for the other Party (which may be house counsel), an opinion, dated the Closing
Date, satisfactory to such party in the form attached hereto as Exhibit B.

                           6.1.6    All material authorizations, consents,
waivers, approvals, orders, registrations, qualifications, designations,
declarations, filings or other actions required with or from any governmental
entity (including without limitation receipt of licenses (or commitments to
issue licenses) to own and operate the Facilities and for the Company following
the Merger to conduct the businesses of the Parties as currently conducted) in
connection with the execution, delivery and performance of this Agreement and
the consummation of the transactions contemplated hereby shall have been duly
obtained and shall be reasonably satisfactory to the Parties, and copies thereof
shall be delivered to the Parties prior to the Closing Date.

                           6.1.7    On the Closing Date, no injunction or order
shall be in effect prohibiting consummation of the transactions contemplated
hereby or which would make the consummation of such transactions unlawful and no
action or proceeding shall have been instituted and remain pending before a
governmental entity to restrain or prohibit the transactions contemplated by
this


                                       41
<PAGE>   45

Agreement and no adverse decision shall have been made by any such governmental
entity which is reasonably likely to materially adversely affect the Company,
the Parties, Newco UHS-1, Newco Q-1 or the Facilities Assets. No federal, state
or local statute, rule or regulation shall have been enacted the effect of which
would be to prohibit, materially restrict, impair or delay the consummation of
the transactions contemplated hereby or materially restrict or impair the
ability of the Company following the Merger to own the Facilities Assets or to
conduct the businesses relating thereto.

                           6.1.8    The Parties' receipt of standard ALTA or

identified on Schedule 2.13, as leasehold owner, as the case may be, subject
only to the Permitted Encumbrances, in the aggregate amount of $50,000,000 for
Valley and $44,300,000 for Desert Springs, and issued by a national title

deleted and will contain a so-called "non-imputation" endorsement and such
additional endorsements as the Parties may reasonably require.

         7.       Nature and Survival of Representations and Warranties;
Indemnification.

                  7.1      Events of Default. A breach as a result of the
failure of a Party to perform any of its agreements, covenants and obligations
under this Agreement, shall be considered a default hereunder giving rise to the
indemnification set forth in Section 7.3 hereof.

                  7.2      Survival of Representations, Etc.  All 
representations and warranties made by the Parties in this Agreement or in any
exhibit, schedules or certificates hereof or in connection with the transactions
contemplated hereby shall terminate at the Closing Date, and thereafter be of no
further force or effect and no action or cause of action on account thereof
shall survive. All other agreements, covenants and obligations of the Parties in
this Agreement or in any exhibit, schedules, certificate, document or instrument
delivered pursuant to the provisions hereof or in connection with the
transactions contemplated hereby, and the remedies of the Parties with respect
thereto, shall survive the closing of the transactions contemplated by this
Agreement.

                  7.3      Indemnification.  From and after the Closing Date,
each Party, as the case may be (an "Indemnifying Party"), severally and not
jointly, shall indemnify and hold the other Party and the Company, as the case
may be, and their respective affiliates, agents and representatives (an
"Indemnified Party"), harmless from and against any and all claims, losses,
expenses, damages or liabilities arising out of or relating to any of the
following: (i) any breach, violation or nonperformance of a covenant, agreement
or obligation


                                       43
<PAGE>   47

to be performed hereunder on the part of any Indemnifying Party; (ii) any claims
against, or liabilities or obligations of an Indemnifying Party not specifically
assumed by an Indemnified Party pursuant to this Agreement; or (iii) any
actions, judgments, costs and expenses (including reasonable attorneys' fees and
all other expenses incurred in investigating, preparing or defending any
litigation or proceedings, commenced or threatened) incident to any of the
foregoing or the enforcement of this Section. In addition to the foregoing,
following the Merger the Parties shall cause the Company to indemnify and hold
the Parties and their affiliates harmless from and against any and all claims,
losses, expenses, damages or liabilities arising out of or relating to the
Company's assumption of the Assumed Liabilities and any actions, judgments,
costs and expenses (including reasonable attorneys' fees and all other expenses
incurred in investigating, preparing or defending any litigation or proceedings,
commenced or threatened) incident to the foregoing. Any indemnification payment
pursuant to the foregoing shall include interest at a floating rate equal to the
prime rate of Citibank N.A., from time to time, from the date the Indemnified
Party provides the Indemnifying Party notice of the loss, cost, expenses or
damages until the date of payment.



                                       44
<PAGE>   48

                  7.4      Representation, Cooperation and Settlement.  (a) An 
Indemnified Party agrees to give prompt written notice to an Indemnifying Party
of any claim against it which might give rise to a claim by such Indemnified
Party based on the indemnity agreement contained in Section 7.3 hereof, stating
the nature and basis of the first-mentioned claim and the amount thereof;
provided, that the failure of the Indemnified Party to give the Indemnifying
Party prompt notice shall not relieve the Indemnifying Party of any of its
obligations hereunder, but may create a cause of action for breach for damages
directly attributable to such delay.

                           (b)      The Indemnifying Party shall have full
responsibility and authority with respect to the payment, settlement, compromise
or other disposition of any third party dispute, action, suit or proceeding
subject to indemnification by such Indemnifying Party hereunder, including,
without limitation, the right to conduct and control all negotiations with
respect to the settlement, compromise or other disposition thereof, and the
Indemnified Party agrees to cooperate with the Indemnifying Party in any
reasonable manner requested by the Indemnifying Party in connection with any
such negotiations. The Indemnified Party shall have the right, without prejudice
to the Indemnifying Party's rights under this Agreement, at the Indemnified
Party's sole expense, to be represented by counsel of its own choosing and with
whom counsel for the Indemnifying Party shall confer in connection with the
defense of any such action, suit or proceeding. The Parties agree to render to
each other such assistance as may reasonably be requested in order to insure the
proper and adequate defense of any such action, suit or proceeding.
Notwithstanding the foregoing, the Indemnifying Party may compromise and settle
any claim, action, or suit to which it must indemnify an Indemnified Party
hereunder, provided that it gives the Indemnified Party advance notice of any
proposed compromise or settlement and shall obtain the consent of


                                       45
<PAGE>   49

the Indemnified Party to such proposed compromise or settlement, which consent
shall not be unreasonably withheld.

         8.       Transactions Subsequent to the Closing Date

                  8.1      Access to Records.  From time to time after the
Closing Date, upon the request of the Company, each Party will provide the
Company with reasonable access to any records, documents and data relating to
the Facilities Assets or any of the Parties retained by any of the Parties
wherever located. From time to time after the Closing Date, upon the request of
either Party, the other Party shall cause the Company to make available to the
requesting Party any records, documents and data relating to the Facilities
Assets acquired by the Company as needed for any lawful purpose (including such
Party's inspection and copying of the same), and each Party shall have the same
rights of access to inspect and copy that such Party had prior to the Closing
Date; provided, however, that any records, documents and data pertaining to a
particular Facility delivered to or made available to such Party and its
representatives will be treated as strictly confidential by such Party and its
representatives, will not be directly or indirectly divulged, disclosed or
communicated to any other person other than such Party and its representatives
who are reasonably required to have access to such information (unless such
Party is compelled to disclose the same by judicial or administrative process),
and will be returned to the Company when such Party's use therefor has
terminated. The Parties shall cause the Company to instruct the appropriate
employees of the Facilities to cooperate in providing access to such records to
the Parties and their authorized representatives as contemplated herein. Access
to such records shall be, wherever reasonably possible, during normal business
hours, with reasonable prior written notice to the Company of the time when such
access shall be needed. The Parties shall cause the Company to provide
sufficient office space to such requesting Party without charge to conduct the
activities described herein. The Parties' employees, representatives and agents
shall conduct themselves in such a manner so that the Company's normal business
activities shall not be unduly or unnecessarily disrupted. For a period of seven
(7) years following the Closing Date, neither of the Parties shall, and each of
the Parties shall cause the Company not to, discard, destroy or otherwise
dispose of records, documents and data relating to the Facilities Assets or the
Parties without first making such records, documents and data available to the
other Party for inspection and copying. The


                                       46
<PAGE>   50

Parties shall cause the Company to retain the records, documents and data
pertaining to a particular Facility at such Facility (or at such other locations
as the Company and the Parties shall determine by their mutual agreement from
time to time) at the Company's cost, until the expiration of seven (7) years
from the Closing Date.

                  8.2      Litigation Cooperation.  After the Closing Date,
upon prior reasonable written request, each Party shall cooperate with the other
and with the Company, at the requesting Party's expense (but including only
out-of-pocket expenses to third parties and not the costs incurred by any Party
for the wages or other benefits paid to its officers, directors or employees),
in furnishing information, testimony and other assistance in connection with any
actions, tax or cost report audits, proceedings, arrangements or disputes
involving any of the Parties hereto (other than in connection with disputes
between the Parties hereto) and based upon contracts, arrangements or acts of
any Party or any of their respective affiliates which were in effect or occurred
on or prior to the Closing Date and which related to the Facilities Assets,
including, without limitation, arranging discussions with, and the calling as
witnesses of, officers, directors, employees, agents and representatives of the
Company.

                  9.1      Methods of Termination.  The transactions

                           (i)      By mutual consent of the Parties; or

                           (ii)     by a Party after March 1, 1998 if any of the
conditions in Section 6.1 to the benefit of such Party shall not have been met
or waived in writing prior to such date.

                  9.2      Procedure Upon Termination.  In the event of
termination pursuant to Section 9.1 hereof, written notice thereof shall
forthwith be given to the other Party and the transactions contemplated by this
Agreement shall be terminated, without further action by any party. If the
transactions contemplated by this Agreement are terminated as provided herein:

work papers and other material of the other Party relating to the transactions
contemplated hereby, whether so obtained before or after the execution of this
Agreement, to the Party furnishing the same; and

                           (ii)     No Party shall have any liability or further
obligation to the other Party to this Agreement other than the confidentiality

course of the negotiations leading to the consummation of the transactions
contemplated hereby (whether obtained before or after the date of this
Agreement), the investigation provided for herein and the preparation of this
Agreement and other related documents, and, in the event the transactions
contemplated hereby shall not be consummated, each Party will return to the
other Party all copies of non-public documents and materials which have been
furnished in connection therewith. The obligation of each Party to treat such
documents, materials and other information in confidence shall not apply to any
