Board of Directors
Henderson & Associates Rehabilitation and
  Sunbelt Therapy Management Services, Inc.

We have audited the accompanying combined balance sheets of Henderson &
Associates Rehabilitation and Sunbelt Therapy Management Services, Inc. as of
December 31, 1995 and 1994, and the related combined statements of operations
and stockholders' equity and cash flows for the years then ended. These
financial statements are the responsibility of the Companies' management. Our
responsibility is to express an opinion on these financial statements based on
our audits.

We conducted our audits in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements are free of material
misstatement. An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements. An audit also includes
assessing the accounting principles used and significant estimates made by
management, as well as evaluating the overall financial statement presentation.
We believe that our audits provide a reasonable basis for our opinion.

In our opinion, the combined financial statements referred to above present
fairly, in all material respects, the combined financial position of Henderson &
Associates Rehabilitation and Sunbelt Therapy Management Services, Inc. at
December 31, 1995 and 1994, and the combined results of their operations and

1. ACCOUNTING POLICIES

DESCRIPTION OF BUSINESS

Henderson & Associates Rehabilitation (HAR) and Sunbelt Therapy Management
Services, Inc. (Sunbelt) provide a variety of therapy services to patients, and
contract their services to hospitals, home health agencies and other
third-parties.

PRINCIPLES OF COMBINATION

The combined financial statements include the accounts of Henderson & Associates
Rehabilitation and Sunbelt Therapy Management Services, Inc. All significant
intercompany accounts and transactions have been eliminated.

USE OF ESTIMATES

The preparation of financial statements in conformity with generally accepted
accounting principles requires management to make estimates and assumptions that
affect the amounts reported in the combined financial statements and
accompanying notes. Actual results could differ from those estimates.

PROPERTY AND EQUIPMENT

Property and equipment are stated at cost. Depreciation of property and
equipment is calculated using the straight-line method over the estimated useful
lives of the assets. Routine maintenance and repairs are charged to expenses as
incurred.

INCOME TAXES

HAR and Sunbelt are S corporations, and taxable income or loss flows through to
the individual stockholders for income tax purposes. Accordingly, no provision
for income taxes or income tax liabilities has been included in the accompanying
combined financial statements.

NET PATIENT SERVICE REVENUE

Net patient service revenue is reported at the estimated realizable amounts from
patients, third-party payors and others for services rendered. HAR and Sunbelt
have negotiated agreements with several organizations to provide therapy
services based on fee schedules.

3. RELATED PARTIES

HAR and Sunbelt share employees and expenses with several organizations of which
the stockholders are owners. However, HAR and Sunbelt have not billed these
organizations for shared activities and have not identified the related costs,
and the accompanying combined financial statements do not include revenue from
these shared activities.

4. EMPLOYEE BENEFIT PLAN

Sunbelt has a qualified defined contribution plan covering all eligible
employees. Contributions are determined based upon a percentage of each eligible
employee's compensation, as defined by management. Contributions to the plan
were approximately $3,809 in 1995 and $3,458 in 1994.

HAR has a profit sharing plan covering all eligible employees. Contributions are
at the discretion of management. No contributions were made to the plan in 1995
or 1994.

5. FAIR VALUE OF FINANCIAL INSTRUMENTS

The following methods and assumptions were used by HAR and Sunbelt in estimating
the fair value of their financial instruments:

Cash, Accounts Payable and Accrued Liabilities: The carrying amounts reported in
the combined balance sheets approximate their fair values.

Long-Term Debt: The fair values of fixed rate issues are estimated using
discounted cash flow analyses based on the current incremental borrowing rates
for similar types of borrowing arrangements. The carrying amounts of all fixed
and variable rate issues approximate their fair values.

6. SUBSEQUENT EVENT

Unison HealthCare Corporation purchased 90% of the common stock of HAR and 
Sunbelt effective February 1, 1996.

   NOTES TO UNAUDITED PRO FORMA CONDENSED COMBINED STATEMENTS OF OPERATIONS

   NOTE 1. PRO FORMA ADJUSTMENTS

   The pro forma results do not purport to present the results of operations
of Unison had the business combinations taken place on the dates specified, nor 
are they necessarily indicative of the financial position or results of 
operations that may be achieved in the future. The Unaudited Pro Forma 
Condensed Combined Statements of Operations have been prepared under the
assumptions set forth in the following notes.

   The adjustments to the pro forma statements of operations are discussed
below:

   (a) On August 10, 1995, Unison purchased all of the outstanding common
stock of BritWill, a long-term care company operating approximately 28
facilities located in Texas and Indiana.

   (b) Effective as of February 1, 1996, Unison acquired 90% of the
outstanding common stock of Sunbelt Therapy.

   (c) Other Acquisitions: The following table summarizes the operating
results for the following leases entered into from January 1, 1995 through the
later of the date of lease inception or the period of the statement of 
operations.

      (d) Operating lease pro forma adjustments represent adjustments to the
pre-lease operating results of the facilities identified in note (c). The
historical results have been adjusted to include the lease expense incurred by
Unison and elimination of the lessor's depreciation, interest expense and
management fees.
      
      (e) In connection with the BritWill Acquisition, general and
administrative expenses have been reduced to give effect to the following
estimated annual cost savings to be realized:

</TABLE>

      (f) To record amortization of a lease liability incurred in connection
with the BritWill Acquisition. The lease liability represents the excess of the
value of BritWill's lease obligations over market lease rates, based on
independent appraisals. Amortization expense related to the lease liability
amounts to approximately $188,000 annually.

                                       12
<PAGE>   13
         (g) To record interest on the debt incurred to acquire Sunbelt. Unison
paid cash in the amount of $800,000, issued promissory notes in the aggregate
amount of $1,000,000 (the "Notes") and issued subordinated convertible
debentures in the aggregate amount of $1,800,000 (the "Debentures"). The Notes
and Debentures bear interest at 10.0%. The Notes and Debentures are convertible
at the option of the holder into shares of Unison common stock based on the
average market price (85% of the average market price with respect to the Notes)
of Unison's stock for the 20 trading days prior to the date of conversion.

         (h) To record interest on debt incurred to acquire BritWill. In
connection with the BritWill Acquisition, Unison issued an $8,000,000 senior
subordinated note bearing interest initially at 8.0%, or $640,000 annually.
Interest expense related to other debt obligations was reduced by $147,000 based
on the anticipated replacement of the accounts receivable sales program with
BritWill's receivables financing program.

         (i) To record amortization of goodwill related to the Sunbelt
Acquisition. Under the purchase method of accounting, assets acquired and
liabilities assumed were recorded at the estimated fair value. The excess of the
$3,600,000 purchase price over the net assets acquired was recorded as goodwill
in the amount of $3,433,000 and is being amortized over 40 years. Such
amortization amounts to approximately $86,000 annually and $21,000 for the
three-month period.

         (j) Under the purchase method of accounting, the BritWill assets
acquired and liabilities assumed were recorded at the estimated fair value as
determined by an independent appraisal. The excess of the purchase price over
the fair value of net assets acquired is being amortized over 40 years, the
noncompete agreement and assembled work force intangible assets are being
amortized over five years, and the lease operating rights intangible assets are
being amortized over the respective lease terms, not to exceed 25 years. Such
amortization is approximately $2,007,000 annually. Amortization expense was
reduced by $829,999 annually to eliminate BritWill's historical amortization of
intangible assets.

         (k) Conversion of the Notes and Debentures was not assumed in the
earnings per share calculation because the effect is antidilutive.

         NOTE 2.  INCOME TAXES

Estimated provisions for income taxes related to pro forma adjustments are based
on an assumed combined federal and state income tax rate of 40%.

time mutually agreeable to Buyer and Seller and shall be held at the offices of

Common Stock for the 20-day trading period immediately preceding the closing for
the purchase and sale of the Retained Stock.

performance of this Agreement nor any document contemplated hereby, nor the
consummation of the transactions contemplated hereby or thereby, will result in

directors of Buyer and Unison regarding the business, properties, prospects and
financial condition of Buyer and Unison and to obtain additional information (to
the extent Buyer or Unison possessed such information or could acquire it
without unreasonable effort or expense) necessary to verify the accuracy of any
information furnished to Seller or to which Seller had access. The foregoing,
does not however limit or modify the representations and warranties of Buyer in
Article 5 of this Agreement or the right of Seller to rely thereon.

4.11: (a) there are no judgments, decrees or orders enjoining any of the
Incorporated Centers in respect of, or the effect of which is to prohibit any
business practice or the acquisition of any property or the conduct of any
aspect of the business of such Incorporated Center; (b) the Incorporated
Centers have complied and are complying with all laws, ordinances, treaties and
governmental rules, orders and regulations applicable to it or its properties,
assets, personnel or business, non-compliance with which could have a Material
Adverse Effect; and (c) each of the Incorporated Centers has obtained all
Licenses necessary for the ownership of its properties and the conduct of its
business as currently conducted, and all such Licenses are currently in full
force and effect.

         4.12. Employees. Except as set forth on Schedule 4.12, none of the
Incorporated Centers has been or is a party to any collective bargaining
agreement with respect to any of its employees or with respect to any contract
or agreement with a labor union or any local or subdivision thereof, nor has it
been charged with any unresolved unfair labor practices, nor is there any
present union organizing activity among any of its employees. There are no
material controversies, claims, suits, actions or proceedings pending or
threatened between any of the Incorporated Centers and any of its respective
employees. Each of the Incorporated Centers has complied in all material
respects with all laws and regulations relating to the employment of labor,
including, without limitation, any provision thereof relating to wages, hours,
employment practices, terms and conditions of employment, collective bargaining,
equal opportunity or similar laws, non-compliance with which could have a
Material Adverse Effect, and the payment of social security and similar taxes,
and is not liable for any arrears of wages or any taxes or penalties for failure
to comply with any of the foregoing.

         4.13. Insurance Coverage. Schedule 4.13 to this Agreement lists all
insurance policies of the Incorporated Centers indicating the risks insured
against, carrier, policy number, amount of coverage (including deductible),
premiums and expiration dates. Except as set forth on Schedule 4.13, such 
policies are in full force and effect and all premiums now due and owing with
respect to such policies have been paid in full, and none of the Incorporated
Centers has made any borrowings or incurred any indebtedness, the collateral
for which was any of such policies.

         4.14.    Employee Benefit Plan(s).

                  (a) Schedule 4.14 lists each Employee Benefit Plan. None of 
the Incorporated Centers has any affiliates for purposes or ERISA.

                  (b) Each Employee Benefit Plan is in substantial compliance
with applicable Law and has been administered and operated in all material
respects in accordance with its terms. Each Employee Benefit Plan which is
intended to be "qualified" within the meaning of Section



                                       15


<PAGE>   21
401(a) of the Code has received a favorable determination letter from the 
Internal Revenue Service and no event has occurred and no condition exists
which could reasonably be expected to result in the revocation of any such
determination. No event which constitutes a "reportable event" (as defined in
Section 4043(b) of ERISA) for which the 30-day notice requirement has not been
waived by the Pension Benefit Guaranty Corporation (the "PBGC") has occurred
with respect to any Employee Benefit Plan. Except as set forth on Schedule 
4.14, no Employee Benefit Plan subject to Title IV or ERISA has been terminated
or is or has been the subject of termination proceedings pursuant to Title IV
or ERISA. Full payment has been made of all amounts which an Incorporated
Center was required under the terms of the Employee Benefit Plan(s) to have
paid as contributions to such Employee Benefit Plan(s) on or prior to the date
hereof (excluding any amounts not yet due) and no Employee Benefit Plan which
is subject to Part 3 of Subtitle B of Title 1 of ERISA has incurred any
"accumulated funding deficiency" (within the meaning of Section 302 of ERISA or
Section 412 of the Code), whether or not waived. Neither the Incorporated
Center nor any other "disqualified person" or "party in interest" (as defined
in Section 4975(e)(2) of the Code and Section 3(14) of ERISA, respectively) has
engaged in any transactions in connection with any Employee Benefit Plan(s)
that could reasonably be expected to result in the imposition of a material
penalty pursuant to Section 502(i) of ERISA, damages pursuant to Section 409 of
ERISA or a tax pursuant to Section 4975(a) of the Code. No material liability,
claim, action or litigation, has been made, commenced or, to the best of
Seller's knowledge, threatened with respect to any Employee Benefit Plan(s)
(other than for benefits payable in the ordinary course and PBGC insurance
premiums). No Employee Benefit Plan or related trust owns any securities in
violation of Section 407 of ERISA. With respect to all Employee Benefit Plan(s)
which are subject to Title IV of ERISA, as of the most recent actuarial
valuation prepared for each such Employee Benefit Plan, the aggregate present
value of the accrued liabilities thereof did not exceed the aggregate fair
market value of the assets allocable thereto. The Incorporated Centers do not
presently maintain or has at any time in the past maintained a "multiemployer
plan" (as defined in Section 4001(a)(3) of ERISA). There are no actions, suits,
or claims (other than routine claims for benefits) pending or threatened
against any Employee Benefit Plan of any of the Incorporated Centers or their
respective assets, or arising out of such Employee Benefit Plan(s) and no facts
exist which could give rise to any such actions, suits or claims or that might
have a Material Adverse Effect on such Employee Benefit Plan(s). There has been
no act or omission by the Incorporated Centers that has given rise or may give
rise to any fines, penalties, taxes or late charges under Section 502(c), (i)
or (1), Section 407(1) of ERISA or Chapter 43 of the Code.

         4.15. Compliance with Environmental Law. Except as set forth in
Schedule 4.15, (i) to Seller's knowledge each of the Incorporated Centers and

Environmental Laws as currently in effect; (ii) neither the Incorporated Centers
nor any of their respective predecessors used, released or disposed of any
Hazardous Substance in any manner; (iii) none of the property owned, leased or
operated by the Incorporated Centers is contaminated by any Hazardous Substance;

                                       16


<PAGE>   22
knowledge none of the property owned, leased or operated by the Incorporated
Centers is affected by any condition that could result in liability under any
Environmental Law as currently in effect; and (v) to Seller's knowledge there is
and has been no condition, activity or event respecting the Incorporated Centers
or any of the properties owned, leased or operated by them that could subject
the Incorporated Centers to any liability under any Environmental Law as
currently in effect.

         4.16. Bank and Brokerage Accounts. Schedule 4.16 lists (i) the names
and addresses of all banks and brokerage firms in which the Incorporated
Centers has accounts or safe deposit boxes, lock boxes, vaults and the account
numbers relating thereto, (ii) the name of each person authorized to draw on
any such account or have access to any such boxes or vaults and (iii) the names
of all persons, if any, holding tax or other powers of attorney from any of the
Incorporated Centers and a summary of the terms thereof.

Seller resulting from or arising in connection with any inaccuracy in responding
or incomplete response to any written request from the Seller for information in
connection with this Agreement, or any inaccuracy in or breach of any
representation or warranty of Buyer or Unison set forth in this Agreement or the
Schedules or Exhibits hereto. Seller acknowledges and agrees that no individual

         6.3. Indemnification Limits. Neither Seller, Buyer nor Unison shall be
liable for any amounts for which such other party is entitled to indemnification
under Section 6.1 or Section 6.2, respectively, as a result of a breach of a

which such party is entitled to indemnification therewith exceeds $10,000, at

such amounts in excess of $10,000. The maximum liability of Buyer and Unison for
indemnification under Section 6.2 shall be limited to the amount then 
outstanding under the Notes and Convertible Debentures. The maximum liability 
of Seller for indemnification under Section 6.1 shall be the Purchase Price.

         6.4. Indemnification Notice. If any third party claim is asserted
against a Person with respect to which such Person is entitled to
indemnification hereunder, such Person (the "indemnified party") shall, within
30 days of the later of the occurrence of the event giving rise to the claim or
the date that the indemnified party learned of such claim (provided, however,
that if a claim arises by virtue of litigation, then in no event less than 15
days prior to the date in which an appearance or answer is due, whichever is
earlier), notify the Person obligated to indemnify it (the "indemnifying party")
of such claim by delivery of a written notice describing the claim and
indicating the basis for indemnification hereunder; provided that the failure to
so notify the indemnifying party shall not relieve the indemnifying party of its
obligations hereunder except to the extent such failure shall have harmed the
indemnifying party. The indemnifying party shall have the right, upon written
notice to the indemnified party within 20 days after receipt from the
indemnified party of notice of such claim, to conduct at its expense the defense
against such claim, to conduct at its expense the defense against such claim in
its own name, or if necessary in the name of the indemnified party. If the
indemnifying party fails to give such notice, it shall be deemed to have elected
not to conduct the defense or the subject claim, and



                                       21


<PAGE>   27
in such event the indemnified party shall have the right to conduct such defense
and, only with the prior consent of the indemnifying party which shall not be
unreasonably withheld, to compromise and settle the claim. If the indemnifying
party does elect to conduct the defense of the subject claim, the indemnified
party shall cooperate with and make available to the indemnifying party such
assistance and materials as may be reasonably requested by it, all at the
expense of the indemnifying party and the indemnified party shall have the right
at its expense to participate in the defense, provided that the indemnified
party will have the right to compromise and settle the claim only with the prior
written consent of the indemnifying party. Any settlement to which the
indemnifying party shall have consented in writing shall conclusively be deemed
to be an obligation with respect to which the indemnified party is entitled to
indemnification hereunder.
