                         UNISON HEALTHCARE CORPORATION
                                AND SUBSIDIARIES
 
                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
 
     1.  The unaudited financial information furnished herein, in the opinion of
management, reflects all adjustments which are necessary to state fairly the
financial position, cash flows and results of operations of Unison HealthCare
Corporation and its subsidiaries ("Unison" or the "Company") as of and for the
periods indicated. The Company's financial statements should be read in
conjunction with the Company's audited consolidated financial statements and
Management's Discussion and Analysis of Financial Condition and Results of
Operations for the year ended December 31, 1996. Footnote and other disclosures
which would substantially duplicate the disclosures contained in Unison's most
recent annual report on Form 10-K have been omitted. Operating results for the
three months and six months ended June 30, 1997 are not necessarily indicative
of the results which may be expected for the year ended December 31, 1997.
 
     In October 1996, Unison completed a merger with two clinical laboratory
companies, American Professional Holding, Inc. and Memphis Clinical Laboratory,
Inc. (together, "Ampro")(the "Ampro Acquisition"). The Ampro Acquisition has
been accounted for as a pooling of interests. Accordingly, the consolidated
financial statements of Unison for the three and six months ended June 30, 1996
have been restated to include the accounts of Ampro.
 
     Certain reclassifications have been made to the 1996 financial statements
to conform to the current year presentation.
 
     2.  Other operating revenues include management fees from third parties
amounting to $85,000 and $227,000 for the three months ended June 30, 1997 and
1996 and $225,000 and $557,000 for the six months ended June 30, 1997 and 1996,
respectively. The provision for doubtful accounts receivable is included in
other operating expenses. Provisions totaled $249,000 and $110,000 for the three
months ended June 30, 1997 and 1996 and $510,000 and $321,000 for the six months
ended June 30, 1997 and June 30, 1996, respectively. The allowance for doubtful
accounts totaled $3,758,000 at June 30, 1997 and $3,776,000 at December 31,
1996.
 
     3.  In January 1997, with a portion of the proceeds from the sale in
October 1996 of $100,000,000 of 12.25% Senior Notes Due 2006 (the "Senior
Notes"), Unison repaid (i) the $8,000,000 subordinated note (the "Subordinated
Note") payable to the former shareholders of BritWill HealthCare Company
("BritWill"), (ii) $1,750,000 of the contingent obligation due to the former
BritWill shareholders (the "Additional Payment Obligation"), (iii) $2,000,000 of
the convertible notes and debentures payable to the former owners of Sunbelt
Therapy (the "Sunbelt Notes") and (iv) other debt obligations in the aggregate
amount of approximately $2,883,000. The remaining balance of the Sunbelt Notes
in the aggregate amount of $800,000 was converted into 105,196 shares of Unison
Common Stock. In accordance with the terms of the Sunbelt Notes, the conversion
price ($7.61) was equal to 85% of the average closing price of Unison's Common
Stock ($8.95) for the 20-day trading period preceding notice of conversion on
November 27, 1996.
 
     The stated interest rate on the Senior Notes is subject to temporary
increase if the Senior Notes (or Exchange Notes with the same terms) are not
registered with the Securities and Exchange Commission (the "Commission") within
specified time periods. As of June 30, 1997, the interest rate was 13.25%. The
interest rate is subject to further increases of 0.25% on September 12, 1997 and
every 90 days thereafter (up to a maximum rate of 14.25%) until such
registration becomes effective.
 
     The terms of certain of Unison's indebtedness and lease obligations require
the Company to meet certain financial covenants, including cash flow to rent
ratios, cash flow to debt service ratios, current ratios and specified minimum
levels of cash and net worth. The Company is also subject to periodic financial
reporting requirements. At June 30, 1997, Unison was not in compliance with
certain of these covenants. At June 30, 1997, Unison was obligated to Omega
Healthcare Investors, Inc. ("Omega") as a tenant under three master lease
agreements covering 14 facilities having an aggregate minimum rent of
approximately $34,900,000 (subject to increase) during the remainder of their
initial terms ending in 2005. The master leases require the Company to maintain
specified cash flow to rent ratios, cash flow to debt service ratios, minimum
cash, current ratios and tangible net worth ratios (each as defined). Unison
also leases six facilities located in Texas from BritWill Texas (the "BritWill
Texas Leases") for an initial term that expires in December 2005. The
                                        6
<PAGE>   7
 
   
BritWill Texas Leases contain cross default provisions with the Omega leases by
which if Unison is in default under any obligation to Omega, the Company is also
in default under the BritWill Texas Leases. Although the Company has made all
required payments, it was not, at June 30, 1997, in compliance with the master
lease financial covenants. The Company continues to be out of compliance with
these covenants after this date and, accordingly, is negotiating with Omega to
restructure such covenants. The Company has not obtained a separate waiver of
the covenant violations from BritWill Texas. Management is attempting to
renegotiate the leases; however, there can be no assurance that such
restructuring will be completed or that Omega will not exercise its remedies of
default under the master lease agreements.
    
 
     In October 1996, Unison acquired Signature Health Care Corporation and
affiliated companies (collectively, "Signature")(the "Signature Acquisition").
In connection with the Signature Acquisition, Unison assumed a 10.5% mortgage
loan (the "Mortgage Note") collateralized by property and equipment of six of
the Signature facilities. The Mortgage Note requires Unison to maintain, among
other things, a consolidated net worth of at least $39,000,000. Unison's
consolidated net worth was $6,161,000 as of June 30, 1997, and, accordingly, the
Company was not in compliance with this covenant. Unison did not receive a
waiver of this covenant violation and, accordingly, classified the entire
obligation of $18,534,000 as current. In addition, the Company has not met the
financial reporting requirements of the Mortgage Note.
 
     4.  Effective January 1, 1997, Unison, through its Sunbelt Therapy
subsidiary, purchased the assets of a rehabilitation therapy services company
located in Mississippi. Consideration for the purchase was comprised of cash
amounting to $600,000 and a $300,000 promissory note. The note bears interest at
10.0%, payable quarterly, and the principal balance is due January 2, 2002.
 
   
     5.  Unison and certain of its current and former directors and officers are
named as defendants in several purported class action complaints seeking
unspecified damages following Unison's announcement in March 1997 that the
Company expected to restate its financial statements for the nine-month period
ended September 30, 1996. See Part II, Item 1, "Legal Proceedings". The Company
denies the material allegations in these complaints and intends to defend the
actions vigorously. While there can be no assurances in such matters, Unison
believes, based on its analysis of the complaints and of its insurance coverage
and communications with its insurance carriers, that the ultimate disposition of
these matters will not adversely affect its liquidity. An adverse determination
in these proceedings, if not covered by insurance, would have a material adverse
impact on the Company's liquidity and results of operations.
    
 
     6.  In accordance with an adjustment provision of the Signature merger
agreements relating to stockholders' equity, in March 1997 the former
shareholders of Signature received additional consideration of $2,511,000, paid
in convertible promissory notes ($1,827,000) (the "Notes") and 238,052 shares of
Unison Common Stock. The adjustment was recorded as an addition to the purchase
price of Signature. The Notes are convertible into shares of Unison Common Stock
at a conversion price of $2.875 per share, subject to adjustment under certain
circumstances. The Notes bear interest at the rate of 12.0% per annum and the
unpaid principal balance, plus accrued interest, is due on December 31, 1997.
The former majority shareholder of Signature is currently serving as interim
Chief Executive Officer, Director and member of the Executive Committee of the
Board of Directors of Unison.
 
     7.  On April 21, 1997, Unison obtained a $2,950,000 loan for general
working capital purposes from affiliates of two of its directors, David A.
Kremser and Bruce H. Whitehead. The loan bears interest at prime plus 2.0% and
was due on the earlier of 30 days notice or August 1, 1997. Messrs. Kremser and
Whitehead have agreed to extend the maturity of this loan until November 1,
1997. The loan is secured by a pledge of certain accounts receivable and the
stock of certain Unison subsidiaries.
 
     8.  In May 1997, Unison announced that the results of operations for the
nine months ended September 30, 1996 were restated from pretax income of
$328,000 to a pretax loss of $15,000,000. No attempt was made to determine the
particular fiscal quarter or quarters to which the adjustments causing the
restatement pertain, and all of the adjustments were confined to the third
quarter of 1996. Because of the considerable costs and difficulty involved and
inasmuch as it would take months of effort to do a precise allocation, if indeed
such an allocation is possible, Unison does not believe it is in the best
interests of its
 
                                        7
<PAGE>   8
 
shareholders to expend the Company's limited resources on that effort and has
instead focused on improving its information systems.
 
   
     9.  Since March 31, 1997, the Company has entered into settlement
agreements in connection with litigation pending on that date. As of June 30,
1997, the Company had accrued approximately $1,684,000 in the aggregate related
to its settlements with Rehabworks, Inc. and Texas Star Therapy, Inc. See Part
II Item 1, "Legal Proceedings".

                    MANAGEMENT'S DISCUSSION AND ANALYSIS OF
                 FINANCIAL CONDITION AND RESULTS OF OPERATIONS
 
     Certain statements contained in this Quarterly Report, including without
limitation statements containing the words "believes", "anticipates", "intends",
"expects" and words of similar import, may be forward-looking statements within
the meaning of Section 27A of the Securities Act of 1933, as amended (the
"Securities Act") and Section 21E of the Securities Exchange Act of 1934, as
amended (the "Exchange Act"). While the Company believes that the assumptions
underlying these statements are reasonable, such assumptions (and thus the
statements based upon them) could prove to be inaccurate. Important factors
which could cause results to vary include limitations on the Company's access to
debt or equity financing in light of recent losses and cash flow shortfalls and
the shift in the listing of the Company's Common Stock from the Nasdaq National
Market to the Nasdaq SmallCap Market, adverse uninsured determinations in
existing or future litigation or regulatory proceedings, health care statutory
or regulatory changes which may disfavor the types of care delivered by the
Company and a reversal of the current limitations in the supply of long-term
care facilities. Important factors which could cause results to vary also
include the factors discussed in Unison's Annual Report on Form 10-K for the
year ended December 31, 1996, in "Item 1 -- Business" and "Item 7 --
Management's Discussion and Analysis of Financial Condition and Results of
Operations -- Risks and Uncertainties", as well as factors discussed elsewhere
in this report or in any document incorporated herein by reference.
 
     The following material should be read in conjunction with the Consolidated
Financial Statements of the Company and the related notes thereto. All
references in this discussion and analysis to years are to fiscal years of the
Company ended December 31 of such year.
 
RESULTS OF OPERATIONS
 
   
     As described in Unison's Annual Report on Form 10-K, the Company
experienced a loss of $23,438,000 for the year ended December 31, 1996. The
Company pursued in late 1995 and in 1996 an aggressive expansion program that,
in time, overwhelmed the Company's financial reporting and management
information systems and personnel and increased its corporate overhead in the
expectation that the number and size of acquisitions would continue to grow.
Unison's financial reporting and management information systems were not
adequate for the larger and more complex needs of the Company, making monitoring
and control over costs more difficult. The Company has taken the following steps
which it believes will help remedy these problems and prevent them from
recurring. First, Unison curtailed its acquisition program in 1997. Second, in
April 1997, Unison accepted the resignations of several of its principal
officers, including its Chief Executive Officer and Chief Financial Officer.
Third, several managers in accounting and finance were replaced in 1997. Fourth,
the Company hired a new CEO in September 1997 and a new CFO in April 1998.
Fifth, in the second quarter of 1997, the Company completed the conversion to
new accounts payable, accounting and financial reporting computer systems.
    
 
   
     The Company is focusing its nursing home marketing efforts on increasing
occupancy levels and improving quality mix in order to increase revenues. Unison
is attempting to increase its ancillary services revenues, both in terms of
acquiring contracts with nonaffiliated facilities and increasing the level of
services provided to its existing patients. The Company is working to reduce
costs without adversely impacting the quality of care it provides. The number of
corporate office personnel was reduced by approximately 35%, from 142 on
December 31, 1996, to 92 on May 15, 1997. These initiatives are designed to
improve both the Company's results of operations and its cash flows.
    
 
     In May 1997, Unison announced that the results of operations for the nine
months ended September 30, 1996 were restated from pretax income of $328,000 to
a pretax loss of $15,000,000. No attempt was made to determine the particular
fiscal quarter or quarters to which the adjustments causing the restatement
pertain, and all of the adjustments were confined to the third quarter of 1996.
Because of the considerable costs and difficulty involved and inasmuch as it
would take months of effort to do a precise allocation, if indeed such an
allocation is possible, Unison does not believe it is in the best interests of
its shareholders to expend the Company's limited resources on that effort and
has instead focused on improving its information systems.

     Unison's revenues fluctuate from facility to facility based on various
factors, including total capacity, occupancy rates, reimbursement methodologies
and rates among the payor categories, payor mix and the scope and utilization of
the Company's ancillary services. Medicare patients generate the highest revenue
per patient day, although profitability is not always increased due to the
additional costs associated with the higher level of care required by such
patients. In general, the Company believes that private pay sources are more
profitable to the Company than governmental reimbursement sources. Unison
generally derives a higher profit margin from ancillary services than from basic
nursing services.
 
     Data for nursing center operations with respect to sources of net patient
revenues and patient mix by payor type are set forth below (long-term care
only).

  Three Months Ended June 30, 1997 Compared to Three Months Ended June 30, 1996
 
   
     In the second quarter of 1997, Unison recorded a net loss of $2,933,000 or
$0.46 per share compared to net income of $976,000 or $0.21 per share in the
prior year quarter. Loss before income taxes amounted to $4,286,000 for the
three months ended June 30, 1997 compared to pretax income of $1,708,000 in the
same period in 1996. The losses in 1997 are primarily attributable to: (i) fixed
costs (rent, interest, depreciation and amortization) increasing to 19.9% of
total revenues for the three months ended June 30, 1997 compared to 13.6% for
the same period in 1996 as a result of financing and acquisition activities; and
(ii) corporate overhead costs (excluding corporate fixed costs) amounting to
8.7% of total revenues for the three months ended June 30, 1997 compared to 3.9%
for the same period in 1996 due in part to the costs associated with the
accounting and information system conversion and relocation to new office space.
These increases in expenses were offset in part by increased pretax earnings
from the Company's therapy, pharmacy and laboratory subsidiaries which
aggregated approximately $2,500,000 for the three months ended June 30, 1997.
    
 
   
     Total operating revenues increased $22,303,000 or 63.6% to $57,368,000 in
the 1997 second quarter from $35,065,000 in the comparable 1996 quarter. The
increase is due to revenues from patient services which increased from
$34,272,000 in the 1996 second quarter to $55,840,000 in the current period.
Patient days increased from 279,425, or 77.0% average occupancy in the 1996
period, to 377,413, or 83.6% average occupancy, in 1997. The increase in patient
days and net patient service revenues is primarily attributable to: (i) the
increase in the number of long-term care facilities operated which increased
revenues by approximately $14,897,000 and patient days by approximately 113,000;
and (ii) the increase in the services provided by the institutional pharmacies
and therapy companies, and progress in providing ancillary products and services
to patients of Unison facilities and unrelated facilities which increased
revenues by approximately $10,300,000. These increases were offset by a
reduction in patient revenues of approximately $774,000 due to the disposition
of four long-term care facilities on March 1, 1997. Other operating revenues
increased to $1,528,000 in the 1997 second quarter from $793,000 in the prior
year quarter due primarily to ancillary company management fees of $1,494,000,
offset by a decrease in managed facilities from six at June 30, 1996 to two at
June 30, 1997.
    
 
     Wages and related expense increased $12,764,000 or 74.2% from $17,202,000
in the 1996 second quarter to $29,966,000 in the 1997 quarter and as a
percentage of revenues from 49.1% in 1996 to 52.2% in 1997. The dollar increase
is due primarily to the increase in the number of facilities operated, an
increase in the services of the ancillary companies and an increase in corporate
and regional wages and related expenses due to Unison's acquisition program
during 1996 and its accounting and information system conversions. The
percentage increase is due primarily to the increase in the services provided by
the therapy companies which have an inherently higher percentage of salaries to
revenues (65.1% for the second quarter of 1997) than long-term care providers
and an increase in corporate and regional overhead.
 
     Other operating expenses increased $8,861,000 or 77.7% from $11,401,000 in
the 1996 second quarter to $20,262,000 in the 1997 second quarter due primarily
to an increase in the number of facilities operated, an increase in the services
of the ancillary companies and increases in corporate operating expenses. Other
operating expenses as a percentage of revenues were 35.3% in the 1997 second
quarter compared to 32.5% in the 1996 period. The percentage increase is due
primarily to an increase in corporate and regional overhead and an increase in
the products provided by the pharmacy and laboratory companies which have an
inherently higher percentage of other operating expenses to revenues than
long-term care providers.

     Rent expense increased $870,000 or 26.7% from $3,263,000 in the 1996 second
quarter to $4,133,000 in the 1997 period but decreased as a percentage of
revenues from 9.3% in the 1996 second quarter to 7.2% in the current quarter.
The dollar increase is due primarily to the increase in the number of leased
facilities operated. The percentage decrease is due to a higher percentage of
owned facilities to total facilities in 1997 than in 1996 and due to the
increased operations of the therapy, laboratory and pharmacy companies, which in
the aggregate, have rent expense of less than 1% of revenues in the 1997 period.
    
 
     Interest expense amounted to $4,936,000 in the 1997 quarter compared to
$874,000 in the 1996 second quarter and increased as a percentage of revenues
from 2.5% in the 1996 second quarter to 8.6% in the 1997 period. The dollar and
percentage increases are primarily the result of debt incurred and assumed in
connection with acquisitions, including the $100,000,000 of Senior Notes issued
on October 31, 1996, as well as increases in borrowings for working capital. See
"-- Liquidity and Capital Resources."
 
     Depreciation and amortization expense increased $1,740,000 from $617,000 in
the second quarter of 1996 to $2,357,000 in the 1997 second quarter and
increased as a percentage of revenues from 1.8% in the 1996 second quarter to
4.1% in the 1997 second quarter. The increase is due primarily to the increase
in goodwill and lease operating rights associated with acquisitions and an
increase in fixed assets resulting from capital expenditures and ownership
interests in six facilities acquired with the acquisition of Signature on
October 31, 1996.
 
     Unison recorded an income tax benefit for the second quarter of 1997
amounting to $1,353,000. The effective tax rate of 31.6% is lower than the
statutory federal income tax rate due primarily to: (i) amortization of
intangible assets and other expenses which are not deductible for tax purposes;
(ii) taxable income of certain subsidiaries which are not consolidated for tax
purposes; and (iii) the valuation allowance established against deferred tax
assets. Unison recorded a tax provision in the 1996 second quarter of $732,000,
or 42.9% of pretax income.
 
  Six Months Ended June 30, 1997 Compared to Six Months Ended June 30, 1996
 
   
     For the six months ended June 30, 1997, Unison recorded a net loss of
$7,015,000 or $1.11 per share compared to net income of $1,519,000 or $.33 per
share of the 1996 period. Loss before income taxes was $10,348,000 compared to
pre-tax income of $2,569,000 for the 1996 period. The losses for the six months
ended June 30, 1997 are primarily attributable to: (i) fixed costs (rent,
interest, depreciation and amortization) increasing to 20.1% of revenues from
13.7% in the 1996 period as a result of financing and acquisition activities;
(ii) corporate overhead costs (excluding corporate fixed costs) amounting to
8.3% of total revenues for the six months ended June 30, 1997 compared to 5.3%
for the 1996 period, due in part to the costs associated with the accounting and
information systems conversion and relocation to new office space; (iii) a
$600,000 charge in the first quarter of 1997 resulting from increasing the
estimated liability recorded for settlement of certain litigation with a therapy
services provider; and (iv) operating losses of the four long-term care
facilities disposed of on March 1, 1997 amounting to $261,000 for the two months
ended February 28, 1997. Pretax earnings from the Company's therapy, pharmacy
and laboratory subsidiaries aggregated approximately $4,365,000 for the six
months ended June 30, 1997.
    
 
   
     Total operating revenues increased $44,544,000 or 65.0% to $113,103,000 for
the six months ended June 30, 1997 from $68,559,000 in the comparable 1996
period. The increase is due to revenues from patient services which increased
from $67,004,000 in the 1996 period to $109,532,000 in the current period.
Patient days increased from 557,965, or 76.8% average occupancy in the 1996
period, to 764,288, or 83.0% average occupancy, in 1997. The increase in patient
days and net patient service revenues is primarily attributable to (i) the
increase in the number of long-term care facilities operated which increased
revenues by approximately $29,239,000 and patient days by approximately 224,000;
(ii) the increase in the services provided by the institutional pharmacies and
therapy companies, and progress in providing ancillary products and services to
patients of Unison facilities and unrelated facilities which increased revenues
by approximately $15,900,000; (iii) an increase in Unison's quality mix to 48.7%
in the 1997 period compared to 48.2% in the prior year period which contributed
to an increase in the revenue per patient day from $104.31 for the six months
ended June 30, 1996 to $112.89 for the 1997 period. These increases were offset
by a reduction in patient revenues of approximately $2,931,000 due to the
disposition of four long-term care facilities on
    
                                       12
<PAGE>   13
 
March 1, 1997. Other operating revenues increased to $3,571,000 in the 1997
period from $1,555,000 in the prior year period due primarily to ancillary
company management fees of $3,113,000, offset by a decrease in managed
facilities from six at June 30, 1996 to two at June 30, 1997.
 
     Wages and related expense increased $25,583,000 or 75.3% from $33,961,000
in the 1996 period to $59,544,000 in the 1997 period and as a percentage of
revenues from 49.5% in 1996 to 52.6% in 1997. The dollar increase is due
primarily to the increase in the number of facilities operated, an increase in
the services of the ancillary companies and an increase in corporate overhead
due to Unison's acquisition program during 1996 and its accounting and
information system conversions. The percentage increase is due primarily to the
acquisition of therapy companies which have an inherently higher percentage of
salaries to revenues than long-term care providers (64.2% for the 1997 period)
and an increase in corporate and regional overhead.
 
     Other operating expenses increased $18,536,000 or 81.8% from $22,665,000 in
the 1996 period to $41,201,000 in the 1997 period due primarily to an increase
in the number of facilities operated, an increase in the services of the
ancillary companies and increases in corporate overhead. Other operating
expenses as a percentage of revenues were 36.4% in the 1997 period compared to
33.1% in the 1996 period due primarily to an increase in corporate and regional
overhead and an increase in the products provided by the pharmacy and laboratory
companies which have an inherently higher percentage of other operating expenses
to revenues than long-term care providers.
 
   
     Rent expense increased $1,682,000 or 25.1% from $6,704,000 in the first six
months of 1996 to $8,386,000 in the 1997 period but decreased as a percentage of
revenues from 9.8% in the 1996 period to 7.4% in the current period. The dollar
increase is due primarily to the increase in the number of leased facilities
operated. The percentage decrease is due to a higher percentage of owned
facilities to total facilities in 1997 than in 1996 and due to the increased
operations of the therapy, laboratory and pharmacy companies, which in the
aggregate, have rent expense of less than 1% of revenues in the 1997 period.
    
 
     Interest expense amounted to $9,594,000 in the current period compared to
$1,508,000 in the 1996 period and increased as a percentage of revenues from
2.2% in the 1996 period to 8.5% in the 1997 period. The increase is primarily
the result of debt incurred and assumed in connection with acquisitions,
including the $100,000,000 of Senior Notes issued on October 31, 1996, as well
as increases in borrowings for working capital. See "-- Liquidity and Capital
Resources."
 
     Depreciation and amortization expense increased $3,574,000 from $1,152,000
in the first six months of 1996 to $4,726,000 in the 1997 period and increased
as a percentage of revenues from 1.7% in the 1996 period quarter to 4.2% in the
1997 period. The increase is due primarily to the increase in goodwill and lease
operating rights associated with acquisitions and an increase in fixed assets
resulting from capital expenditures and ownership interests in six facilities
acquired with the acquisition of Signature on October 31, 1996.
 
     Unison recorded an income tax benefit for the first six months of 1997
amounting to $3,333,000. The effective tax rate of 32.2% is lower than the
statutory federal income tax rate due primarily to: (i) amortization of
intangible assets and other expenses which are not deductible for tax purposes;
(ii) taxable income of certain subsidiaries which are not consolidated for tax
purposes; and (iii) the valuation allowance established against deferred tax
assets. Unison recorded a tax provision in the 1996 period of $1,050,000, or
40.9% of pretax income.
 
  Recent Accounting Pronouncements
 
     In March 1997, the Financial Accounting Standards Board issued Statement of
Financial Accounting Standards No. 128, "Earnings Per Share" ("SFAS 128"). SFAS
128 changes the manner in which earnings per common share ("EPS") are calculated
and presented. Under SFAS 128, two EPS amounts are required: (i) basic EPS; and
(ii) diluted EPS. Basic EPS is computed by dividing income available to common
stockholders by the weighted average number of common shares actually
outstanding during the period. Diluted EPS represents the per share allocation
of income attributable to common stockholders based on the weighted average
number of common shares actually outstanding plus dilutive potential common
shares outstanding such as options, warrants and convertible securities. Unison
will be required to implement
 
                                       13
<PAGE>   14
 
SFAS 128 as of December 31, 1997. Had the Company implemented SFAS 128 on
January 1, 1996, it would have reported basic and diluted EPS for the three
months ended June 30, 1996 of $0.22 and $0.21, respectively. For the six months
ended June 30, 1996, the Company would have reported basic and diluted EPS of
$0.35 and $0.33, respectively. Loss per share for the three and six months ended
June 30, 1997 would remain unchanged at $0.46 and $1.11 for both the basic and
diluted calculations, as the Company's options, warrants and convertible notes
are antidilutive.
 
LIQUIDITY AND CAPITAL RESOURCES
 
     At June 30, 1997, Unison had $2,413,000 in cash and cash equivalents (which
includes $2,240,000 of checks written in excess of bank balance in accounts
payable) compared to $17,409,000 at December 31, 1996. The Company had a working
capital deficit of $18,985,000 at June 30, 1997 compared to a working capital
deficit at December 31, 1996 amounting to $13,955,000. Current maturities of
notes and debt at June 30, 1997 amounted to $28,888,000, of which $19,134,000 is
classified as a current liability because Unison is not in compliance with
certain financial covenants as discussed below. However, although the financial
covenant violations have not been cured, management has no reason to believe
that this debt will be accelerated and required to be paid off in 1997.
 
   
     Cash used in operations in the six months ended June 30, 1997 amounted to
$5,857,000, due primarily to the net loss of $7,015,000, net of non-cash items
of $1,850,000.
    
 
   
     Net accounts receivable increased 21.7% or $6,210,000 from $28,608,000 at
December 31, 1996 to $34,818,000 as of June 30, 1997 primarily due to collection
issues resulting from Medicare intermediary changes, one new facility certified
to participate in the Medicare program, high turnover in the business office
staff of the nursing centers and reductions in the field accounting staffs who
are primarily responsible for collections of accounts receivable. As of June 30,
1997, days outstanding in accounts receivable for the long-term care facilities
increased to 43 from 38 days outstanding at December 31, 1996. The Company is
actively monitoring the collection of accounts receivable and does not believe
that these events will effect the ultimate collectability of these receivables.
The allowance for doubtful accounts decreased as a percentage of receivables
from 11.7% at December 31, 1996 to 9.7% at June 30, 1997. The Company
anticipates that its allowance for doubtful accounts will fluctuate in the
future and will depend, in large part, on the mix of revenues, as well as the
timing of payments by private, third-party and governmental payors. While the
Company believes that the allowance for doubtful accounts is adequate at June
30, 1997, if the current accounts receivable increase trend continues, the
provision for bad debts will increase in future periods.
    
 
   
     Net cash used in investing activities amounted to $3,098,000 in the six
months ended June 30, 1997. Capital expenditures amounted to $1,635,000 and
expenditures for acquisitions, net of cash acquired, amounted to $592,000.
    
 
   
     Net cash used in financing activities amounted to $6,041,000 in the six
months ended June 30, 1997 due primarily to the repayment of notes and long-term
debt of $13,699,000, including $12,196,000 paid to affiliates, offset by an
increase in borrowings under the revolving line of credit amounting to
$7,511,000 and a reduction of $2,087,000 from December 31, 1996 in checks
written in excess of bank balances. At June 30, 1997, Unison had $157,098,000 in
total debt (96.2% of total capitalization) compared to $157,138,000 at December
31, 1996 (93.1% of total capitalization). The Company also had, at June 30,
1997, aggregate minimum rent obligations of approximately $157,000,000 (subject
to certain increases) during the remainder of the initial terms and first
renewal periods under non-cancelable lease arrangements.
    
 
     In January 1997, Unison repaid with proceeds from the Senior Notes the
$8,000,000 Subordinated Note payable to the former BritWill shareholders and
$1,750,000 of the Additional Payment Obligation due to the former BritWill
shareholders. Thereafter, Unison's remaining obligation associated with the
acquisition of BritWill is the Additional Payment Obligation amounting to
$9,671,000 as of June 30, 1997. The Additional Payment Obligation is payable in
monthly installments of $117,000 to $166,000, which include interest at 12.0% to
14.0%, with a balloon payment of $8,146,000 due August 9, 2000. Because these
payments are contingent upon revenue targets that, in light of recent
acquisitions, are likely to be achieved, the Additional Payment Obligation is
recorded as long-term debt and an increase in lease operating rights in the
consolidated
                                       14
<PAGE>   15
 
balance sheets at December 31, 1996 and June 30, 1997. Although this accounting
treatment does not change the amount of cash due to the former BritWill
shareholders, Unison will record an increase in amortization and interest
expense in 1997 compared to 1996 in the aggregate amount of approximately
$1,600,000 ($800,000 for the first six months of 1997). In the event of a sale
by Unison prior to August 9, 2000 of debt or equity securities exceeding
$10,000,000, the remaining balance of the Additional Payment Obligation will be
due in full.
 
     Also in January 1997, Unison repaid $2,000,000 of the Sunbelt Notes with
proceeds from the Senior Notes, and the remaining $800,000 principal amount was
converted into 105,196 shares of Unison Common Stock. The conversion
price($7.61) was equal to 85% of the average closing price of Unison's Common
Stock ($8.95) for the 20-day trading period preceding notice of conversion on
November 27, 1996.
 
     In accordance with an adjustment provision of the Signature merger
agreements relating to stockholders' equity, in March 1997 the former
shareholders of Signature received additional consideration of $2,511,000, paid
in convertible promissory notes ($1,827,000) (the "Notes") and 238,052 shares of
Unison Common Stock. The Notes are convertible into shares of Unison Common
Stock at a conversion price of $2.875 per share, subject to adjustment under
certain circumstances. The Notes bear interest at the rate of 12.0% per annum
and the unpaid principal balance, plus accrued interest, is due on December 31,
1997.
 
   
     On April 21, 1997, Unison obtained a $2,950,000 loan for general working
capital purposes from affiliates of two of its directors, David A. Kremser and
Bruce H. Whitehead. This loan matured on November 1, 1997. On September 25,
1997, Unison borrowed an additional $1.0 million from Messrs. Kremser and
Whitehead which was due on October 7, 1997. The loans bear interest at prime
plus 2.0% and are secured by a pledge of certain accounts receivable and the
stock of certain Unison subsidiaries. Unison is currently in default on its
obligations to repay these loans. In addition to the foregoing, the loan
documents state that the collateral pledged for the working capital loans also
collateralized all other obligations which may be due to these individuals
and/or entities which they control; and further that all such obligations are in
default due to cross default provisions in those loan and security documents.
All of these obligations total, in the aggregate, approximately $18.9 million as
of September 30, 1997. The Company has not obtained a waiver of the defaults on
its obligations in the loan and security documents described above. An
acceleration of Unison's obligations under these financial instruments could
have a material adverse effect on Unison.
    
 
   
     Unison finances its working capital needs with cash provided by its
operations and draws under a $10,000,000 revolving credit facility. Borrowings
under this credit facility amounted to $7,511,000 at June 30, 1997 with interest
at the prime rate plus 4.0% (12.5% at June 30, 1997). There were no outstanding
borrowings under this credit facility at December 31, 1996. In March 1997,
Unison paid a management fee (in lieu of a termination fee) of $500,000. The
lender agreed that the existing facility would remain in place at Unison's
option until December 31, 1997 (subsequently extended to June 30, 1998). At July
31, 1997, $8,333,000 (the maximum amount available based on current levels of
collateral) was outstanding under this line of credit with interest at 12.5% per
annum.
    
 
   
     The Company believes that, absent additional financing, its cash flows from
operations and draws under its existing $10,000,000 line of credit will not be
sufficient to meet all of its debt service requirements in 1997 and beyond.
    
 
   
     On December 1, 1997, Unison completed the private placement of $20.0
million of its 13% Senior Notes due 1999 (the "13% Notes"). The net proceeds to
the Company of $19.2 million were used for debt service, including the
semiannual payment of interest on the 12.25% Senior Notes amounting to $6.7
million, and for working capital. The Company has not made the interest payment
due March 1, 1998 on the 13% Notes in the amount of $650,000.
    
 
   
     The Company has been working since July 1997 on a plan designed to: (a)
reduce its costs of capital and operating expenses to improve operating results;
(b) provide short-term and long-term liquidity; and (c) restructure its balance
sheet and increase stockholders' equity. The key elements of the plan include:
    
 
                                       15
<PAGE>   16
 
   
(i) reductions in controllable costs as described in "-- Results of Operations";
(ii) obtaining a new revolving line of credit secured by its eligible accounts
receivable; (iii) completing a refinancing of the Mortgage Note incurred in
connection with the Signature Acquisition; and then, (iv) depending on market
conditions, an equity infusion. The Company is currently seeking to replace the
Mortgage Note (and to refinance one of its leased facilities which is subject to
a purchase option) with new financing in the amount of up to $40.0 million. The
Mortgage Note had a balance at September 30, 1997 of $18.5 million. Proceeds
from these financing transactions would be used for debt service and working
capital. There is no assurance that the Company will be successful in effecting
any refinancing of the Mortgage Note.
    
 
   
     Even if the Company is successful in completing refinancing transactions of
the type it is currently seeking, it will still not have sufficient liquidity to
meet all of its short- and long-term debt service and capital requirements,
absent significant asset sales or a substantial restructuring of its debt and
lease obligations. Some of these obligations are already in default, as
described herein. Market conditions permitting, Unison may seek to raise
additional equity through the private placement of stock, but there can be no
assurance that any such equity financing will be available.
    
 
   
     If the Company completes the recapitalization plans outlined above, it may
incur a charge to earnings of up to $2,500,000 from prepayment penalties and
write-off of deferred financing costs for those obligations which are proposed
to be paid off.
    
 
   
     Unison's recapitalization plan may be affected by covenants under the
Senior Notes unless Unison's fixed charge ratio after incurring the indebtedness
would be greater than 2 to 1 (2.25 to 1 after December 31, 1997). The Senior
Notes generally limit Unison's debt incurrance to an amount equal to (1) the
greater of $30 million of secured indebtedness or the sum of 60% of inventory
plus 90% of accounts receivable and (2) the greater of $10 million of other
indebtedness or 10% of Unison's consolidated net worth (in addition to
indebtedness outstanding on October 31, 1996 after giving effect to the
application of the proceeds from the Senior Notes and refinancings of such
indebtedness). As of June 30, 1997, Unison had incurred approximately
$17,490,000 of such secured and other indebtedness. There can be no assurance
that the Company will obtain the necessary consents from its lessors and debtors
in the future if it attempts to engage in one of the aforementioned types of
transactions.
    
 
   
     Because of the substantial losses reported by the Company in 1996, it does
not currently satisfy the minimum tangible net asset requirement for the listing
of its common stock on the Nasdaq National Market's National Market System. On
August 20, 1997, the Company was advised by Nasdaq of its decision to move the
Company's securities to The Nasdaq SmallCap Market, effective August 22, 1997,
pursuant to a waiver to the $3 per share initial inclusion bid price
requirement. On February 23, 1998, new, more stringent quantitative maintenance
requirements for continued listing on the Nasdaq SmallCap Market went into
effect. Unison does not currently meet these requirements, and on April 15,
1998, its securities were delisted by Nasdaq. The Company is unable to determine
what effect, if any, the delisting of its stock will have on its ability to
effect the aforementioned private placement of stock.
    
 
     The stated interest on the Senior Notes has temporarily increased to 13.25%
at August 31, 1997 and it is subject to further increases at 90-day intervals
(to a maximum of 14.25%) until a registration statement for the Senior Notes (or
for Exchange Notes on the same terms) is filed and is declared effective by the
Securities and Exchange Commission. Unison delayed filing the required
registration statement while it completed work on its financial statements for
1996. Unison made the filing on July 3, 1997, but it has not yet become
effective. Further delays in completing the required registration, with
corresponding additional interest expense on the Senior Notes, are likely.
 
   
     The terms of certain of Unison's indebtedness and lease obligations require
the Company to meet certain financial covenants including cash flow to rent
ratios, cash flow to debt service ratios, current ratios and specified minimum
levels of cash and net worth. The Company is also subject to periodic financial
reporting requirements. At June 30, 1997, Unison was not in compliance with many
of these covenants. At June 30, 1997, Unison was obligated to Omega as a tenant
under three master lease agreements covering 14 facilities having an aggregate
minimum rent of approximately $32,996,000 (subject to increase) during the
remainder of their initial terms ending in 2005. The master leases require the
Company to maintain specified cash flow to
    
                                       16
<PAGE>   17
 
   
rent ratios, cash flow to debt service ratios, minimum cash, current ratios and
tangible net worth. Unison also leases six facilities located in Texas from
BritWill Texas for an initial term that expires in December 2005. The lease
agreement with BritWill Texas requires the Company to pay to Omega monthly
amounts equal to (i) the amount of loan payments due to Omega from BritWill
Texas pursuant to a loan agreement between those parties, which provided the
financing for BritWill Texas' acquisition of the facilities and (ii) lease
payments on the facilities that are subleased by BritWill Texas to Unison. The
BritWill Texas Leases contain cross default provisions with the Omega leases by
which if Unison is in default under any obligation to Omega, the Company is also
in default under the BritWill Texas Leases. The Company was not, at June 30,
1997, in compliance with the master lease financial covenants and did not obtain
a waiver of the covenant violations from Omega or BritWill Texas. The Company
continues to be out of compliance with these covenants after this date and,
accordingly, is negotiating with Omega to restructure such covenants. There can
be no assurance that such restructuring will be accomplished, or if
accomplished, that the restructuring will result in more favorable terms to
Unison and its stockholders. Unison was, at December 31, 1997, in arrears of its
rent obligations under these leases in the approximate amount of $1.3 million
plus late charges. On January 7, 1998, three of Unison's subsidiaries (BritWill
Investments-I, Inc., BritWill Investments-II, Inc., and BritWill Indiana
Partnership) filed for protection under Chapter 11 of the federal bankruptcy
laws. These subsidiaries operate a total of 26 facilities in Texas and Indiana
including the facilities leased from Omega and BritWill Texas. The filings were
necessitated by actions taken by Omega to terminate or otherwise enforce
contractual arrangements under the leases. The subsidiary filings do not affect
Unison's operations outside of Texas and Indiana.
    
 
   
     In connection with the Signature Acquisition, Unison assumed a 10.5%
mortgage loan (the "Mortgage Note") collateralized by property and equipment of
six of the Signature facilities. The Mortgage Note requires Unison to maintain,
a consolidated net worth of at least $39,000,000. Unison's consolidated net
worth was $6,161,000 as of June 30, 1997, and, accordingly, the Company was not
in compliance with this covenant. Unison has not received a waiver of this
covenant violation and, accordingly, classified the entire obligation of
$18,534,000 as current. In addition, the Company has not met the financial
reporting requirements of the Mortgage Note. The Company is current on its
payments on the Mortgage Note and the lender has not indicated any intention to
declare the Company in default. In the event of a declaration of default, Unison
may be required to repay the Mortgage Note or the lender may foreclose on the
properties, which would adversely impact Unison's results of operations. While
the Company does not believe, based on discussions with the lender, that a
declaration of default will occur, it is considering a refinancing of the
Mortgage Note as discussed above. With the exception of the aforementioned
classification of the Mortgage Note as a current liability, there was no
financial statement impact as of and for the six months ended June 30, 1997 as a
result of the Company's covenant defaults on its debt and lease agreements.
    
 
   
     Because the Company's cash flows from operations and its available capital
have been insufficient to meet its current operating expenses, lease obligations
and debt service requirements, the Company is currently in covenant and payment
default in the terms of material operating leases and indebtedness. In the
absence of obtaining additional capital through the refinancing of the Mortgage
Note, asset sales, securing an increased revolving credit facility, consensual
restructuring of debt and lease terms and/or similar measures, the Company will
be unable to remedy the existing defaults and will experience additional
defaults in the future. The Company's operating leases are subject to
termination in the event of default, and the Company's indebtedness may be
accelerated in the event of continuing default. Certain lenders could foreclose
on Company assets securing their indebtedness, which would include substantially
all of the Company's operating assets. Accordingly, the Company's financial
condition could require that the Company seek additional protection under
applicable reorganization laws in order to avoid or delay actions by its
creditors and lessors which could materially adversely affect or cause the
cessation of the Company's operations.
    
 
   
     Unison and certain of its current and former directors and officers are
named as defendants in several purported class action complaints seeking
unspecified damages following Unison's announcement in March 1997 that the
Company expected to restate its financial statements for the nine-month period
ended September 30, 1996. See Part II, Item 1, "Legal Proceedings." While there
can be no assurances in such matters, Unison believes, based on its analysis of
the complaints and of its insurance coverage and
    
 
                                       17

communications with its insurance carriers, that the ultimate disposition of
these matters will not adversely affect its liquidity. An adverse determination
in these proceedings, if not covered by insurance, would have a material adverse
impact on the Company's liquidity and results of operations.

ITEM 1.  LEGAL PROCEEDINGS
 
     Unison and certain of its current and former directors and officers are
named as defendants in several purported class action complaints following
Unison's announcement in March 1997 that the Company expected to restate its
financial statements for the nine-month period ended September 30, 1996. To
date, the following actions have been filed in federal district court in
Phoenix, Arizona:
 
     Martin Grossman FBO Martin Grossman Profit Sharing Plan, and Alan S.
     Fellheimer v. Unison HealthCare Corporation, Jerry M. Walker, Craig R.
     Clark and Paul J. Contris, Case No. CIV 97-0583.
 
     Leonard Goldstein and Ronne Goldstein v. Unison HealthCare Corporation,
     Jerry M. Walker, Craig R. Clark and Paul J. Contris, Case No. CIV 97-0584.
 
     Toni Kaasbell v. Unison HealthCare Corporation, Craig R. Clark and Paul J.
     Contras [sic], Case No. CIV 97-0602.
 
     Joseph Grimes v. Unison HealthCare Corporation, Jerry M. Walker, Craig R.

     R. Rollins, Jerry M. Walker, Craig R. Clark and Paul J. Contris, Case No.
     CIV 97-0825.
 
     Karl E. Falkenstein v. Unison HealthCare Corporation, Bruce H. Whitehead,
     Phillip R. Rollins, Jerry M. Walker, Craig R. Clark and Paul J. Contris,
     Case No. CIV 97-1017.
 
     Dr. Stanley Levine as Trustee for Lakeside Urology Limited Employee Profit
     Sharing Trust and Lakeside Urology Limited Employee Pension Plan v. Unison
     HealthCare Corporation, Jerry M. Walker, Craig R. Clark and Paul J.
     Contris, Case. No. CIV 97-1412.
 
     The purported class periods asserted in these actions vary, with the
broadest such period beginning December 18, 1995 (when Unison commenced the
initial public offering of its stock (the "IPO")) and ending March 11, 1997
(when Unison announced the need for a restatement). The complaints in all these
actions allege violations of Sections 10 and 20 of the Exchange Act and Rule
10b-5 thereunder in that the defendants allegedly knew, or were reckless in not
knowing, that Unison's results for the first three quarters of 1996 were
materially overstated or misrepresented the capability of Unison's internal
accounting system to reliably record and reflect its financial condition.
Amended complaints in two of these actions (Grossman et al. v. Unison HealthCare
Corporation et al. and Goldstein et al. v. Unison HealthCare Corporation et al.)
also allege violations of Sections 11 and 15 of the Securities Act in that the
registration statement covering, and the prospectus used in connection with the
stock sold in, the IPO allegedly misleadingly touted Unison's "growth strategy"
and ability to control costs while failing to disclose inadequacies in its
accounting system. Two actions (Amothy Corp. v. Unison HealthCare Corporation et
al. and Falkenstein v. Unison HealthCare Corporation et al.) also allege that
the conduct giving rise to the alleged Exchange Act violations also violated the
defendants' state law fiduciary duties as directors and officers. The individual
defendants include Jerry M. Walker, Craig R. Clark and Paul J. Contris, at the
time of their resignations in April 1997, the President and Chief Executive
Officer, Executive Vice President and Chief Financial Officer and Executive Vice
President -- Acquisitions and Development, respectively, of the Company, and
Bruce H. Whitehead and Phillip R. Rollins, currently Chairman of the Board and
Executive Vice President and Chief Operating Officer, respectively, of the
Company. The plaintiffs in these purported class actions seek compensatory
damages in unspecified amounts plus interest, attorneys' fees and costs.
 
     In addition, an action styled Jeffrey D. VanDyke v. Cruttenden Roth, Inc.,
Wheat First Butcher Singer, Bruce H. Whitehead, Unison HealthCare Corp., John T.
Lynch, Jr., Trouver Capital Partners, L.P., Jerry M. Walker, Phillip R. Rollins,
Craig R. Clark and Paul J. Contris has been filed in the Superior Court of the
State of California (County of Orange) (Case No. 779111). Defendant John T.
Lynch, Jr., is a member of the Board of Directors of Unison. Trouver Capital
Partners, L.P. is a private investment banking firm of which Mr. Lynch is a
general partner, and Cruttenden Roth, Inc., and Wheat First Butcher Singer are
investment
                                       19

banking firms that are named individually and as representatives of a purported
defendant underwriter class. The Orange County action is purportedly filed on
behalf of all persons who acquired Unison common stock in the Company's IPO; it
essentially alleges that in connection with the IPO the defendants made positive
statements in the prospectus and registration statement concerning the Company's
prospects, for which there was no basis, that accounts receivable were
overstated and that the Company's statement of financial position as of
September 30, 1995 was not fairly presented. The plaintiff seeks compensatory
damages in an unspecified amount as well as interest, attorneys' fees and costs
and extraordinary, equitable and injunctive relief as permitted by law or
equity.
 
   
     Unison's bylaws require the Company to indemnify current and former
officers and directors to the extent permitted by Delaware law against
liabilities represented by the above described actions and related expenses. The
Company is also obligated to indemnify the underwriters, subject to certain
conditions, against such liabilities and expenses. The Company denies the
material allegations in these complaints and intends to defend the actions
vigorously. While there can be no assurances in such matters, Unison believes
that, based on its analysis of the complaints and of its insurance coverage and
communications with its insurance carriers, the ultimate disposition of these
matters will not adversely affect its liquidity. An adverse determination in
these proceedings, if not covered by insurance, would have a material adverse
impact on the Company's liquidity and results of operations.
    
 
   
     Certain of the Company's subsidiaries were defendants in an action styled
Texas Star Therapy, Inc. v. Emory Care Center, Inc., et al. that was filed in
June 1996 in the District Court of Shelby County, Texas, and subsequently
transferred (as Cause No. 96-07767-B) to Dallas County. Plaintiff sought
$517,000 in unpaid fees for therapy services rendered as well as interest,
penalties, attorneys' fees and costs. Pursuant to the terms of a settlement
agreement entered into in May 1997, Unison is obligated to remit to the
plaintiff the sum of $875,000 in a series of payments that commenced in June and
culminated in November 1997.
    
 
   
     The Company also reached agreement, in July 1997, with the plaintiff in an
action styled Rehabworks, Inc. v. Unison HealthCare Corp., BritWill
Investments-II, Inc. and Sunbelt Therapy Management Services, Inc., being Cause
No. 366-1483-96 filed in the District Court of Collin County, Texas, and served
on the Company in October 1996. The complaint in this action alleged that the
Company was in arrears in the payment of fees for therapy services rendered in
the amount of $1,031,000 and that, in addition, Unison breached a
nonsolicitation covenant in a contract with Rehabworks and tortiously interfered
with Rehabworks' employment relationship with several of its former employees.
The suit sought to recover such fees as well as damages of not less than
$2,375,000, exemplary damages of not less than $2,250,000, interest and
attorneys' fees. Unison is obligated, under the terms of the agreement providing
for the settlement of this action, to pay the plaintiff the principal amount of
$1,029,000 plus interest at 11% per annum in 24 consecutive monthly installments
commencing October 1, 1997.
    
 
   
     Another Unison subsidiary is the defendant in an action entitled
Carillon/Alpha Limited v. BritWill HealthCare Company filed, and assigned Cause
No. 96-5742, in the District Court of Dallas County, Texas. Plaintiff in this
action seeks compensatory damages in the amount of $216,000, allegedly for
unpaid rent, for the three-month period during which premises leased to the
subsidiary were vacant and the cost of releasing same, plus interest and
attorneys' fees. Unison, which has asserted various defenses and intends
vigorously to defend this lawsuit, believes that an adverse outcome would not
have a material effect on its financial condition or results of operations.
