                  (In thousands, except per share information)

(1)    BASIS OF PRESENTATION

       The accompanying unaudited condensed consolidated financial statements
       have been prepared in accordance with generally accepted accounting
       principles for interim financial reporting and the instructions to Form
       10-Q and Article 10 of Regulation S-X. Accordingly, they do not include
       all of the information and footnotes required by generally accepted
       accounting principles for complete financial statements. Interim results
       are not necessarily indicative of results that may be expected for the
       full year.

       In the opinion of management, the accompanying unaudited interim
       financial statements contain all material adjustments, consisting only of
       normal recurring adjustments, necessary to present fairly the
       consolidated financial position, results of operation and cash flows of
       New American Healthcare Corporation (the "Company") for the interim
       periods presented.

       For further information, refer to the consolidated financial statements
       and footnotes thereto included in the Company's Annual Report on Form
       10-K for the year ended March 31, 1999.

(2)    ASSET WRITE-DOWN, TRANSITION AND OTHER RELATED COSTS

       Asset write-down, transition and other related costs totaling
       approximately $29,628 were recorded during the three months ended June
       30, 1999. These charges were comprised of approximately $28,895 of asset
       write-down costs, $703 of severance costs and $30 of other related costs.

       Assets held for sale totaled approximately $17,861 at June 30, 1999, and
       consisted of current assets, property and equipment and other assets from
       three hospitals associated with the asset write-down during the three
       months ended June 30, 1999. The Company expects to dispose of the assets
       during the year ended March 31, 2000. Net revenue and pre-tax losses from
       the hospitals to be disposed of totaled $13,262 and $2,012, respectively,
       for the three months ended June 30, 1999. Net revenue and pre-tax income
       from the hospitals to be disposed of totaled $11,464 and $459,
       respectively, for the three months ended June 30, 1998.

(3)    SUBSEQUENT EVENTS

       Effective August 1, 1999, the Company sold Davenport Medical Center to a
       health care system. The value received approximated the net carrying
       value of Davenport Medical Center.

OVERVIEW

         New American acquires and operates acute care hospitals throughout the
United States. The Company was formed to capitalize on opportunities to be the
principal provider of health care services in those non-urban communities which
it targets.

         The Company acquired its first hospital in August 1996 and through June
1999 has acquired ten additional hospitals. These eleven acute care hospitals
are located in nine states and have a total of 1,347 licensed beds.

IMPACT OF ACQUISITIONS

         Because of the financial impact of the Company's recent acquisitions,
it is difficult to make meaningful comparisons between the Company's financial
statements for the fiscal periods presented. In addition, due to the relatively
small number of hospitals currently operated, each hospital can materially
affect the overall operating margins of the Company. Upon the acquisition of a
hospital, the Company typically takes a number of steps intended to lower
operating costs. The impact of such actions may be offset by the cost of revenue
enhancing initiatives such as expanding services, strengthening medical staff,
and improving market position. The benefits of these investments and of other
activities to improve operating margins generally do not occur immediately.
Consequently, the financial performance of a newly acquired hospital may
initially have an adverse effect on the Company's overall operating margins. The




                                                                               5
<PAGE>   8


operating results of acquisitions are included in the Company's results of
operations from the respective dates of purchase.

RESULTS OF OPERATIONS

         Net operating revenue is comprised of net patient service revenue and
other revenue. Net patient service revenue is reported net of contractual
adjustments and policy discounts. The adjustments principally result from
differences between the hospitals' customary charges and payment rates under the
Medicare and Medicaid programs and other third-party payors. Customary charges
have generally increased at a faster rate than the rate of increase for Medicare
and Medicaid payments. Other revenue includes cafeteria sales, medical office
building rental income and other miscellaneous revenue. Operating expenses
primarily consist of hospital related costs of operation and include salaries
and benefits, professional fees (includes medical professionals and consulting
services), supplies, provision for doubtful accounts, and other operating
expenses (principally consisting of utilities, insurance, property taxes,
travel, freight, postage, telephone, advertising, repairs and maintenance).
General and administrative expenses primarily relate to corporate overhead.

         The following table presents, for the periods indicated, information
expressed as a percentage of net operating revenue. Such information has been
derived from the Consolidated Statements of Operations of the Company included
elsewhere in the report.

</TABLE>


(1)      EBITDA represents the sum of income before income tax expense,
         interest, and depreciation and amortization. Management understands
         that industry analysts generally consider EBITDA to be one measure of
         the financial performance of a company that is presented to assist
         investors in analyzing the operating performance of the company and its
         ability to service debt. Management believes that an increase in EBITDA
         level is an indicator of the Company's improved ability to service
         existing debt, to sustain potential future increases in debt and to
         satisfy capital requirements. However, EBITDA is not a measure of
         financial performance under generally accepted accounting principles




                                                                               6

         and should not be considered an alternative (i) to net income as a
         measure of operating performance or (ii) to cash flows from operating,
         investing, or financing activities as a measure of liquidity. Given
         that EBITDA is not a measurement determined in accordance with
         generally accepted accounting principles and is thus susceptible to
         varying calculation, EBITDA, as presented, may not be comparable to
         other similarly titled measures of other companies.

THREE MONTHS ENDED JUNE 30, 1999 COMPARED TO THREE MONTHS ENDED JUNE 30, 1998

         Net operating revenue was $50.0 million for the three months ended June
30, 1999, compared to $35.9 million for the comparable period of 1998, an
increase of $14.1 million or 39.3%. Net operating revenue for the hospitals
owned during both three months ended June 30, 1999 and 1998, excluding hospitals
held for sale, was $25.3 and $24.4 million, respectively. Net operating revenue
for the hospitals held for sale owned during both three months ended June 30,
1999 and 1998 was $8.6 and $11.5 million, respectively. This total decrease for
hospitals owned during both periods is primarily due to managed care pricing
pressures in three markets, lower-than-expected volume growth and a slow down in
physician recruitment.

         Operating expenses less depreciation and amortization and interest were
$78.0 million, or 156.0% of net operating revenue, for the three months ended
June 30, 1999, compared to $32.4 million, or 90.3% of net operating revenue, for
the comparable period of 1998. Operating expenses less depreciation and
amortization and interest for the hospitals owned during both three months ended
June 30, 1999 and 1998, excluding hospitals held for sale, was $44.9 and $21.8
million, respectively. Operating expenses less depreciation and amortization and
interest for the hospitals held for sale owned during both three months ended
June 30, 1999 and 1998 was $18.7 and $10.6 million, respectively. This total
increase for hospitals owned during both periods is primarily due to $29.6
million of asset write-down, transition and other related costs during the three
months ended June 30, 1999.

         Depreciation and amortization expense was $2.2 million for the three
months ended June 30, 1999, compared to $1.4 million for the comparable period
of 1998, an increase of $0.8 million or 57.1%. The increase is primarily due to
an increase in depreciation expense relating to acquisitions and a $0.7 million
increase in capital expenditures for the three months ended June 30, 1999.

         Interest expense was $2.4 million for the three months ended June 30,
1999, compared to $1.6 million for the comparable period of 1998, an increase of
$0.8 million or 50.0%. The increase was due to the increase in average
outstanding indebtedness associated with the eleven hospitals owned during the
three months ended June 30, 1999 versus only eight hospitals having been owned
for the comparable period of 1998. The average debt outstanding for the three
months ended June 30, 1999 and 1998 was $104.3 and $36.5 million, respectively,
bearing interest at a rate of 9.0% and 8.2% at the end of each respective
period.

LIQUIDITY AND CAPITAL RESOURCES

          At June 30, 1999, the Company had working capital of $43.6 million
including cash and cash equivalents of $1.9 million. The ratio of current assets
to current liabilities was 3.0 to 1.0 at June 30, 1999 and 2.0 to 1.0 at March
31, 1999.

         On August 20, 1998, the Company completed its initial public offering
("IPO") of common stock, selling five million shares at $13.00 per share,
netting the Company approximately $58.0 million. Net



                                                                               7
<PAGE>   10

proceeds of the offering were used to pay dividends on and to redeem all of the
Series A preferred stock ($26.3 million), to pay interest on and prepay all of
the subordinated debt ($26.4 million) and to reduce indebtedness under the
Company's revolving credit facility ($5.0 million). Concurrent with the IPO, the
then outstanding Series B convertible preferred stock was converted into 1.4
million and 2.8 million shares of non-voting and voting common stock,
respectively.

         On May 14, 1999, the Company amended and restated its revolving credit
agreement. The credit agreement has a revolving credit limit of $116.0 million.
Borrowings under the facility bear interest of (i) a base rate equal to the
greater of the Prime Rate or the Federal Funds rate, plus in either case, a
margin of up to 2.75% or (ii) London Interbank Offered Rate as of the date of
borrowing plus a margin of up to 4%. The applicable margin is determined by a
ratio of indebtedness to EBITDAR, as defined in the Credit Agreement, calculated
on a monthly basis. The facility is due and payable November 30, 2002, with a
required permanent reduction of $12.0 and $8.0 million by October 31, 1999 and
2000, respectively. Additionally, the Company is required to pay down
outstanding indebtedness upon the sale of any facilities and beginning with the
year ended March 31, 2000, by the amount of any excess cash flow for the year,
as defined within the agreement, less $4.0 million of cash and cash equivalents
to be maintained by the Company. At June 30, 1999, $106.3 million of the Credit
Facility was drawn, an increase of $3.0 million from March 31, 1999. At June 30,
1999, the average borrowing rate on the Credit Facility was 9.0%.

         Cash flows used in operating activities were $5.7 million for the three
months ended June 30, 1999 compared to cash flows provided by operating
activities of $1.1 million for the comparable period of 1998. Cash used in
investing activities was $1.1 million for the three months ended June 30, 1999
and $0.7 million for the three months ended June 30, 1998, primarily related to
the acquisition of equipment. Net cash provided by financing activities was $2.8
million for the three months ended June 30, 1999, primarily from bank borrowings
related to working capital expenditures. Net cash used in financing activities
was $6.4 million for the three months ended June 30, 1998, primarily from
repayment of $6.0 million of debt.

         The Company continually reviews its capital needs and financing
opportunities and may seek additional equity or debt financing for these or
other needs. There can be no assurance that the Company will not require
additional debt or equity financing or that such financing will be available on
acceptable terms. Effective August 1, 1999, the Company sold Davenport Medical
Center to a health care system. The value received approximated the net carrying
value of Davenport Medical Center. The Company is exploring the sale of up to
two additional hospitals during fiscal year 2000. During the three months ended
June 30, 1999, the Company wrote down the assets of the facilities, which it
intends to sell. The funds provided by any dispositions will be used to pay down
outstanding indebtedness on the revolving credit facility.

         Capital expenditures, excluding acquisitions, for the three months
ended June 30, 1999 and 1998 were $1.4 million and $0.7 million, respectively.
Capital expenditures related to management information systems ("MIS") (both
financial and clinical) were approximately $0.2 million for the three months
ended June 30, 1999. Capital expenditures for the Company's hospitals will vary
from year to year depending on facility improvements and service enhancements
undertaken. The Company expects to fund fiscal year 2000 capital needs with
excess operating cash flows and borrowings from the revolving credit facility.

         The Company previously announced its intentions to sell Crosby Memorial
Hospital. The Company is obligated to build a new, replacement facility for
Crosby Memorial Hospital within 36 months of the November 1, 1998 acquisition
date. If the Company fails to meet this commitment, the Company must purchase
the existing facility for $15.0 million.

YEAR 2000 ISSUES

         Many currently installed computer systems and software products are
coded to accept only two-digit entries in the date code field. By the year 2000,
these date code fields will need to accept four-digit entries to distinguish
21st century dates from 20th century dates. These products include software
applications running on desktop computers and network servers as well as in
microchips and microcontrollers incorporated into equipment. Certain of the
Company's computer hardware and software, building infrastructure components
(e.g. alarm systems and HVAC systems) and medical devices that are date
sensitive, may contain programs with the Year 2000 problem. Computer systems,
which do not include four-digit entries, could fail or produce erroneous results
causing disruptions of operations or affect patient diagnosis and treatment. As
a result, many software and computer systems may need to be upgraded or replaced
in order to comply with such Year 2000 requirements.

         Status of the Company's Year 2000 Compliance

         MIS. The Company is in the process of converting all of its hospitals
to a new management information system (MIS), which it believes is Year 2000
compliant. As of June 30, 1999, nine of the Company's eleven hospitals had been
converted to the new system. The Company expects the remaining two hospitals to
be converted by October 1999. The provider of the MIS has represented to the
Company that the new system is Year 2000 compliant and the Company's testing of
the system has not indicated any material Year 2000 noncompliance.

         Non-MIS Equipment. Various clinical and non-clinical equipment
currently in use at the Company's hospitals incorporates time/date elements. The
Company has substantially completed an itemized inventory of all of its
hospitals and identified substantially all equipment with potential Year 2000
problems. The Company believes it will have completed this process and
established a time frame for repairing or replacing any non-compliant equipment
by September 30, 1999. The Company is also in the process of contracting its
group-purchasing agent to determine any Year 2000 compliance problems with
respect to its sources of supplies. The Company has not received sufficient
information from its group purchasing agent to determine any Year 2000
compliance problems with respect to its sources of supplies or to establish an
estimated date for completing subsequent phases with respect to its supplies. In
addition, the Company has established a plan to inventory the infrastructure in
each of its hospitals to determine any Year 2000 compliance problems. The
Company expects to complete its Year 2000 compliance plan with respect to the
hospital's infrastructure by December 31, 1999.

         Third-Party Relationships. In addition, the Company has ongoing
relationships with third-party suppliers, vendors, payors and others, which may
have computer systems with Year 2000 compliance problems that the Company does
not control. Medicare is a significant source of revenues to the Company.
According to the Health Care Financing Administration ("HCFA") web page, the
Medicare program will be ready to process acceptable claims in the Year 2000.
However, there can be no assurance that the fiscal intermediaries and
governmental agencies with which the Company transacts business and which are
responsible for payment to the Company under Medicare and Medicaid programs, as
well as other payors, will not experience problems with Year 2000 compliance. In
addition, the Company depends upon other vendors such as utilities, which
provide electricity, water, natural gas and telephone services and vendors of
medical supplies and pharmaceuticals used in patient care. As a part of its Year
2000 strategy, the Company intends to seek assurances from these parties that
their services and products will not be interrupted or malfunction due to the
Year 2000 problem and expects to complete the initial contacting of these
parties by September 30, 1999. The failure of such third parties to remedy Year
2000 problems could




                                                                              9

have a material adverse effect on the Company's business, financial condition
and results of operations and ability to provide health care services.

         Costs of Year 2000 Compliance

         The Company expects to make capital expenditures of approximately $7.5
million which includes (i) approximately $6.3 million for the new MIS software
and hardware, of which $4.8 million was expended in fiscal year 1999 and $0.2
million was expended in the three months ended June 30, 1999 and (ii) certain
non-MIS costs associated with Year 2000 compliance. The Company does not expect
to incur any other additional material Year 2000 compliance costs. The failure
of the Company's MIS to be Year 2000 compliant could have a material adverse
effect on the Company's business, financial conditions and results of
operations.

         Risks Related to Year 2000 Issues

         The Company believes that it will be able to resolve its Year 2000
compliance problems before December 31, 1999; however, the Company has not yet
completed all of the phases of its Year 2000 compliance program. The failure of
the new MIS program, the non-MIS equipment or the hospital infrastructure to be
Year 2000 compliant could have a material adverse effect on the Company's
business, financial condition and results of operations. The failure of any of
the foregoing could result in the Company's inability to diagnose or treat
patients, bill for patient services, or collect payment from patients or
third-party payors. Finally, if there are such disruptions generally in the
economy as a result of Year 2000 compliance problems, such disruptions could
have a material adverse effect on the Company. The Company is unable to estimate
the amount of the potential liability or lost revenue at this time.

         The Company believes that the most likely worst case scenario of Year
2000 compliance problems is that some third-party payors will not be Year 2000
compliant. The failure of such third-party payors to be Year 2000 compliant
could result in delays and difficulties in receiving payments from such payors
for services provided by the Company. These problems could result from the
inability to file claims with certain payors by electronic filings as well as
such payors inability to process either electronic or paper filings. These
problems could seriously impact the Company's cash flows. The Company intends to
develop a contingency plan to address this scenario. It is expected that such a
plan would involve establishing procedures whereby the Company would revert to
manual billing processes and ensuring access to additional capital in case of
cash flow problems.

         Contingency Plans for Year 2000 Issues

         The Company intends to complete an initial contingency plan by August
31, 1999. However, in some instances (e.g. loss of water supply), the Company
may not be able to develop contingency plans which allow the affected hospital
to continue to operate. Each of the Company's hospitals has a disaster plan,
which will be reviewed as a part of the Company's contingency planning process.

         The foregoing is based on information currently available to the
Company. The Company will revise its strategy as it completes its assessment of
Year 2000 issues. The Company can provide no assurances that applications and
equipment the Company believes to be Year 2000 compliant will not experience
difficulties or that the Company will not experience difficulties obtaining
resources needed to make modifications to or replace the Company's affected
systems and equipment. Failure by the Company or third parties on which it
relies to resolve Year 2000 issues could have a material adverse effect on the




                                                                              10

Company's results of operations and its ability to provide health care services.
Consequently, the Company can give no assurances that issues related to Year
2000 will not have a material adverse effect on the Company's financial
condition or results of operations.

ENVIRONMENTAL MATTERS

         The Company acquired Puget Sound Hospital in Tacoma, Washington in
September 1999. During its due diligence process, the Company discovered certain
environmental contamination involving underground storage tanks no longer in
use. Environmental consultants have developed a work plan to remediate such
existing contamination, which must be approved by the Washington State
Department of Ecology. Once the work plan is approved, remediation may begin.
The prior owner has agreed to fund all costs of such remediation.

         Although the Company is not currently aware of any other material
environmental claims pending or threatened against it or any of its hospitals,
no assurances can be given that a material environmental claim will not be
asserted against the Company or against any of its hospitals. The costs of
defending against claims of liability, or of remediating a contaminated
property, could have a material adverse effect on the Company's business,
financial condition and results of operations.

INFLATION

         The health care industry is labor intensive. Wages and other expenses
increase, especially during periods of inflation and labor shortages. In
addition, suppliers pass along rising costs to the Company in the form of higher
prices. The Company has generally been able to offset such increases in
operating costs by its cost containment activities and expanding services. In
light of reimbursement measures imposed by government agencies and private
insurance companies, the Company is unable to predict its ability to offset or
control future cost increases, or its ability to pass on the increased costs
associated with providing health care services to patients with government or
managed care payors, unless such payors correspondingly increase reimbursement
rates.

GENERAL

         Hospital revenue is received primarily from Medicare, Medicaid and
commercial insurance. The federal Medicare program accounted for approximately
53.3% and 63.3% of hospital patient days for the three months ended June 30,
1999 and 1998, respectively. The state Medicaid programs accounted for
approximately 19.8% and 16.7% of hospital patient days for the three months
ended June 30, 1999 and 1998, respectively. The Company's percentage of revenue
received from the Medicare program is expected to increase due to the general
aging of the population. The payment rates under the Medicare program for
inpatients are prospective, based upon the diagnosis of a patient. The Medicare
payment rate increases have historically been less than actual inflation. In
addition, numerous states, insurance companies and employers are actively
negotiating discounts to the Company's standard rates. The trend towards
increased managed care, including a shift in payor mix toward health maintenance
organizations, preferred provider organizations and other managed care payors,
may also adversely affect payment rates for the Company's services and the
Company's ability to achieve targeted growth rates in net patient service
revenue.

         Both federal and state legislators are continuing to scrutinize the
health care industry for the purpose of reducing health care costs. While the
Company is unable to predict what, if any, future health reform legislation may
be enacted at the federal or state level, the Company expects continuing
pressure to limit



                                                                              11

<PAGE>   14


expenditures by governmental health care programs. Payments for Medicare
outpatient services provided at acute care hospitals and home health services
historically have been paid based on costs, subject to certain limits. The
Balanced Budget Act of 1997 requires that the payment for those services be
converted to a prospective payment system, which will be phased in over time.
The 1997 Act also includes a managed care option, which could direct Medicare
patients to managed care organizations. Further changes in the Medicare or
Medicaid programs and other proposals to limit health care spending could have a
material adverse impact upon the health care industry and the Company.

         The Company's acute care hospitals, like most acute care hospitals in
the United States, have significant unused capacity. The result is substantial
competition for patients and physicians. Inpatient utilization continues to be
negatively affected by payor-required pre-admission authorization and by payor
pressure to maximize outpatient and alternative health care delivery services
for less acutely ill patients. The Company expects increased competition and
admission constraints to continue in the future. The ability to respond
successfully to these trends, as well as spending reductions in governmental
health care programs, will play a significant role in determining the hospitals'
ability to maintain their current rate of net revenue growth and operating
margins.

         The Company expects the industry trend from inpatient to outpatient
services to continue due to the increased focus on managed care and advances in
technology. Outpatient revenue of the Company's hospitals was approximately
42.5% and 43.0% of gross patient service revenue for the three months ended June
30, 1999 and 1998, respectively.

         The complexity of the Medicare and Medicaid regulations, increases in
managed care, hospital personnel turnover, the dependence of hospitals on
physician documentation of medical records and the subjective judgment involved
complicates the billing and collections of accounts receivable by hospitals.
There can be no assurance that this complexity will not negatively impact the
Company's future cash flow or results of operations.

         The federal government and a number of states are rapidly increasing
the resources devoted to investigating allegations of fraud and abuse in the
Medicare and Medicaid programs. At the same time, regulatory and law enforcement
authorities are taking an increasingly strict view of the requirements imposed
on providers by the Social Security Act and Medicare and Medicaid regulations.
Although the Company believes that it is in material compliance with such laws,
a determination that the Company has violated such laws, or even the public
announcement that the Company was being investigated concerning possible
violations, could have a material adverse effect on the Company.




                                                                              12

ACCOUNTING PRONOUNCEMENTS

         In June 1998, the Financial Accounting Standards Board issued Statement
133, Accounting for Derivative Instruments and Hedging Activities, which is
effective for all fiscal quarters of fiscal years beginning after June 15, 2000.
This statement establishes accounting and reporting standards for derivative
instruments, including derivative instruments imbedded in other contracts and
for hedging activities. It requires that entities recognize all derivatives as
either assets or liabilities in the statement of financial position and measure
those instruments at fair value. The Company does not presently have any
derivative financial instruments and does not believe that this statement will
have a material impact on its financial position or results of operations.
