2.  INTERIM FINANCIAL STATEMENTS

The unaudited condensed consolidated financial statements of the Company
included herein have been prepared in accordance with generally accepted
accounting principles for interim financial statements and do not include all of
the information and disclosures required by generally accepted accounting
principles for annual financial statements. These financial statements should be
read in conjunction with the consolidated financial statements and related
footnotes included as part of the Company's Annual Report on Form 10-K for the
period ended June 30, 1999 filed with the Securities and Exchange Commission
(SEC) on September 28, 1999. In the opinion of management, all adjustments
(consisting of normal recurring accruals) necessary for fair presentation of
results for the period have been included. The results of operations for the
nine months ended March 31, 2000 are not necessarily indicative of the results
to be achieved for the full fiscal year.

Certain reclassifications have been made to conform prior year amounts to the
current year presentation.

3.  INVESTMENTS IN AND TRANSACTIONS WITH PARTNERSHIPS

The consolidated financial statements include the accounts of the Company and
its wholly owned subsidiaries. The Company's investment interests in
partnerships or limited liability companies (Partnerships) are accounted for

Partnerships and does not have primary responsibility for the Partnerships'
long-term debt. The Company's investment interests in Partnerships are
consolidated for ownership of 50% or greater owned entities when the Company
exercises significant control over the operations and is primarily responsible
for the associated long-term debt.

4.   INCOME PER COMMON AND CONVERTED PREFERRED SHARE

The Company reports basic and diluted earnings per share (EPS) for common and
converted preferred stock. The number of shares used in computing EPS is equal
to the weighted average number of common and converted preferred shares
outstanding during the respective period. Since the preferred stock has no
stated dividend rate and participates in any dividends paid with respect to the
common stock, the as-if-converted amounts are included in the computation of
basic EPS. There were no adjustments to net income (the numerator) for purposes
of computing EPS.

A reconciliation of basic and diluted share computations is as follows:

5.   SUBSEQUENT EVENT

On May 2, 2000, the Company entered into a definitive agreement to purchase a
90% interest in a partnership, which owns a Center in Wilkes-Barre,
Pennsylvania. The completion of the transaction is subject to customary
closing conditions and the expiration of the waiting period under the
Hart-Scott-Rodino Antitrust Improvements Act of 1976. The closing is expected
to occur on or before June 15, 2000.

6.   SUPPLEMENTAL CONDENSED CONSOLIDATED FINANCIAL INFORMATION

The Company's payment obligations under the 9 5/8% senior subordinated notes are
guaranteed by certain of the Company's wholly owned subsidiaries (the Guarantor
Subsidiaries). Such guarantees are full, unconditional and joint and several.
Separate financial statements of the Guarantor Subsidiaries are not presented
because the Company's management has determined that they would not be material
to investors. The following supplemental financial information sets forth, on an
unconsolidated basis, balance sheets, statements of income, and statements of
cash flows information for the Company (Parent Company Only), for the Guarantor
Subsidiaries and for the Company's other subsidiaries (the Non-Guarantor
Subsidiaries). The supplemental financial information reflects the investments
of the Company and the Guarantor Subsidiaries in the Guarantor and Non-Guarantor
Subsidiaries using the equity method of accounting.

ITEM 2. MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS
OF OPERATIONS

The statements contained in this report that are not purely historical or which
might be considered an opinion or projection concerning the Company or its
business, whether express or implied, are forward-looking statements within the
meaning of the Private Securities Litigation Reform Act of 1995. These
statements may include statements regarding the Company's expectations,
intentions, plans or strategies regarding the future, including statements
related to the Year 2000 Issue. All forward-looking statements included in this
report are based upon information available to the Company on the date hereof,
and the Company assumes no obligation to update any such forward-looking
statements. It is important to note that the Company's actual results could
differ materially from those described or implied in such forward-looking
statements because of certain factors which could affect the Company. Such
forward-looking statements should be evaluated in light of the following
factors: availability of financing; limitations and delays in reimbursement by
third party payors; contract renewals and financial stability of customers;
technology changes; governmental regulations; conditions within the health care
environment; Year 2000 issues; adverse utilization trends for certain diagnostic
imaging procedures; aggressive competition; general economic factors; successful
integration of acquisitions; and the risk factors described in the Company's
periodic filings with the SEC on Forms 10-K, 10-Q and 8-K (if any) and the
factors described under "Risk Factors" in the Company's Registration Statement
on Form S-4, filed with the SEC on August 4, 1998, and any amendments thereto.

ACQUISITIONS

The Company believes a consolidation in the diagnostic imaging industry is
occurring and is necessary in order to provide surviving companies the
opportunity to achieve operating and administrative efficiencies through
consolidation. The Company's strategy is to further develop and expand regional
diagnostic imaging networks that emphasize quality of care, produce
cost-effective diagnostic information and provide superior service and
convenience to its customers. The strategy of the Company is focused on the
following components: (i) to further participate in the consolidation occurring
in the diagnostic imaging industry by continuing to build its market presence in
its existing regional diagnostic imaging networks through geographically
disciplined acquisitions; (ii) to develop or acquire additional regional
networks in strategic locations where the Company can offer a broad range of
services to its customers and realize increased economies of scale; (iii) to
continue to market current diagnostic imaging applications through its existing
facilities to optimize and increase overall procedure volume; (iv) to strengthen
the regional diagnostic imaging networks by focusing on managed care customers;
and (v) to implement a variety of new products and services designed to further
leverage its core business strengths, including: Open MRI systems and the
radiology co-source product which involves the joint ownership and management of
the physical and technical operations of a single or multi-modality facility on
a hospital campus. The Company believes that long-term viability is contingent
upon its ability to successfully execute its business strategy.

In fiscal 1999, the Company completed two acquisitions as follows: a 70%
interest in a partnership which owns four Centers and two Fixed Facilities in
Buffalo, New York; and a 100% interest in three Centers and two Fixed Facilities
in Phoenix, Arizona. The aggregate purchase price for these two acquisitions
was approximately $16.9 million.

In fiscal 2000, the Company completed the acquisition of two Fixed Facilities
located in Indianapolis and Clarksville, Indiana, respectively. The purchase
price for these acquisitions was approximately $6.9 million.

In fiscal 2000, the Company opened its second radiology co-source outpatient
Fixed Facility in Granada Hills, California, and an Open MRI Fixed Facility
in Pleasanton, California, which were financed with internally generated
funds. Effective December 31, 1999, the Company closed an Open MRI Fixed
Facility in Atlanta, Georgia.

In the fourth quarter of fiscal 2000, the Company opened its third radiology
co-source outpatient Center in Henderson, Nevada, which was financed with
internally generated funds. Also, in the fourth quarter of fiscal 2000, the
Company entered into a definitive agreement to purchase a 90% interest in a
partnership, which owns a Center

                                       18
<PAGE>
in Wilkes-Barre, Pennsylvania. The completion of the transaction is subject to
customary closing conditions and the expiration of the waiting period under the
Hart-Scott-Rodino Antitrust Improvements Act of 1976. The closing is expected
to occur on or before June 15, 2000.

FINANCIAL CONDITION, LIQUIDITY AND CAPITAL RESOURCES

The Company operates in a capital intensive, high fixed cost industry that
requires significant amounts of working capital to fund operations, particularly
the initial start-up and development expenses of new operations and yet is
constantly under external pressure to contain costs and reduce prices. Revenues
and cash flows have been adversely affected by an increased collection cycle,
competitive pressures and major restructurings within the health care industry.
This adverse effect on revenues and cash flow is expected to continue.

The Company continues to pursue acquisition opportunities. The Company believes
that the expansion of its business through acquisitions is a key factor in
maintaining profitability. Generally, acquisition opportunities are aimed at
increasing revenues and operating income, and maximizing utilization of existing
capacity; however, the Company has incurred and will continue to incur certain
associated costs, including the salaries, benefits and travel expenses of its
business development team. Incremental operating income resulting from future
acquisitions will vary depending on geographic location, whether facilities are
Mobile or Fixed, the range of services provided and the Company's ability to
integrate the acquired businesses into its existing infrastructure. Since 1996,
the Company has completed eleven acquisitions. No assurance can be given,
however, that the Company will be able to identify suitable acquisition
candidates and thereafter complete such acquisitions on terms acceptable to the
Company.

The Company has outstanding $100 million of 9 5/8% senior subordinated notes
(Notes). The Notes mature in June 2008, with interest payable semi-annually and
are redeemable at the option of the Company, in whole or in part, on or after
June 15, 2003. The Notes are unsecured senior subordinated obligations of the
Company and are subordinated in right of payment to all existing and future
indebtedness, as defined in the indenture, of the Company, including borrowings
under the bank financing described below. The terms of the Notes contain certain
restrictions on the Company's ability to take certain actions without first
obtaining consent of the noteholders.

The Company also has the following credit facilities with Bank of America,
N.A.: (i) a $50 million term loan which expires in June 2004, (ii) a $25
million working capital facility which expires in June 2003, and (iii) a $75
million acquisition facility which expires in June 2004, the availability of
which expires on June 12, 2000 (Bank Financing). Borrowings under the Bank
Financing bear interest at LIBOR plus 1.75%. The Company is required to pay
an annual unused facility fee of between 0.375% and 0.5%, payable quarterly,
on unborrowed amounts under the working capital and acquisition facilities,
of which the Company paid approximately $0.3 million during the nine months
ended March 31, 2000. At March 31, 2000, there was (i) approximately $36.9
million in borrowings under the term loan, (ii) approximately $8.0 million in
borrowings under the working capital facility, and (iii) approximately $22.2
million in borrowings under the acquisition facility. As of April 30, 2000,
the Company had borrowing availability of approximately $20 million and $51
million under the working capital facility and the acquisition facility,
respectively. If the acquisition of the interest in the partnership described
above is completed, $31 million will be available under the acquisition
facility through June 12, 2000, or such extension date, as discussed below.
The Company believed that it would fully utilize the acquisition facility
prior to its expiration since it has been and continues to be involved in
discussions with several acquisition candidates; however, the Company does
not expect to completely utilize the facility prior to its expiration. The
Company is currently negotiating an extension to the availability of the
acquisition facility through June 12, 2001. While the Company believes an
extension will be obtained, no assurance can be given that such extension
will be obtained on terms acceptable to the Company, or at all. If the
facility is not extended, and the Company is unable to obtain alternate
financing sources, the Company would have to utilize its own internally
generated funds to complete future acquisitions.

Net cash provided by operating activities was approximately $21.4 million for
the nine months ended March 31, 2000. Cash provided by operating activities
resulted primarily from net income before depreciation and amortization
(approximately $28.9 million) and an increase in accounts payable and other
accrued expenses (approximately $1.5 million), offset by an increase in trade
accounts receivables (approximately $8.2 million). The increase in trade
accounts receivables is due primarily to the Company's acquisition and
development activities. It is also the result of the conversion of the Company's
contract services billing system, which the Company believes will be a
short-term increase.

Net cash used in investing activities was approximately $22.2 million for the
nine months ended March 31, 2000. Cash used in investing activities resulted
primarily from the (i) Company purchasing or upgrading diagnostic

                                       19
<PAGE>

imaging equipment at its existing facilities (approximately $13.6 million), (ii)
the acquisition described above (approximately $6.9 million), and (iii)
purchasing or upgrading diagnostic imaging equipment at the facilities acquired
in fiscal 1999 described above (approximately $1.4 million).

Net cash provided by financing activities was approximately $0.5 million for the
nine months ended March 31, 2000, resulting primarily from (i) borrowings under
the working capital facility described above (approximately $5.0 million) and
(ii) borrowings under the acquisition facility (approximately $7.7 million),
offset by principal payments of debt and capital lease obligations
(approximately $12.4 million).

The Company has committed to purchase or lease in connection with the
development of new Mobile Facilities and replacement of diagnostic imaging
equipment at Centers, Fixed and Mobile Facilities, at an aggregate cost of
approximately $16 million, 11 MRI systems for delivery through December 31,
2000. The Company expects to use either internally generated funds or leases
from General Electric Company (GE) to finance the purchase of such equipment. In
addition, the Company previously committed to purchase or lease from GE, 24 Open
MRI systems for delivery and installation. As of March 31, 2000, the Company had
taken delivery of 19 of such Open MRI systems and had cancelled orders for three
of such systems without further obligation to GE. The remaining two systems are
included in the commitments discussed above. The Company may purchase, lease or
upgrade other MRI systems as opportunities arise to place new equipment into
service when new contract services agreements are signed, existing agreements
are renewed, acquisitions are completed, or new imaging centers are developed in
accordance with the Company's business strategy.

Effective December 1, 1999, the Company purchased 38 pieces of diagnostic
imaging equipment from GE by converting operating leases to capital leases. The
capital leases bear interest at 9% per annum, have 48 to 72 month terms and
contain a $1.00 buyout at the end of each lease. The total purchase price was
approximately $45 million. For the quarter ended March 31, 2000, equipment lease
expense was reduced by approximately $3.0 million, and depreciation and interest
combined was increased by approximately the same amount. The Company also
purchased four pieces of diagnostic imaging equipment which were also financed
through capital leases with GE. The total purchase price was approximately $7.0
million.

The Company believes that, based on current levels of operations and
anticipated growth, its cash from operations, together with other available
sources of liquidity, including borrowings available under the Bank
Financing, will be sufficient through June 30, 2001 to fund anticipated
capital expenditures and make required payments of principal and interest on
its debt, including payments due on the Notes and obligations under the Bank
Financing. In addition, the Company continually evaluates potential
acquisitions and expects to fund such acquisitions from its available sources
of liquidity, including borrowings under the Bank Financing, provided that
the acquisition facility is extended through June 12, 2001, as discussed
above. Moreover, the Company's acquisition strategy may require sources of
capital in addition to that currently available to the Company, and no
assurance can be given that the Company will be able to raise any such
necessary additional funds on terms acceptable to the Company or at all.

RESULTS OF OPERATIONS

NINE MONTHS ENDED MARCH 31, 2000 COMPARED TO MARCH 31, 1999

REVENUES: Revenues increased approximately 19.0% from approximately $117.6
million for the nine months ended March 31, 1999, to approximately $140.0
million for the nine months ended March 31, 2000. This increase was due
primarily to the acquisitions and opened Fixed Facilities discussed above
(approximately $11.6 million) and an increase in contract services and patient
services revenues (approximately $11.7 million) at existing facilities, offset
by a decrease in other revenues (approximately $0.9 million), primarily due to a
one-time settlement payment in connection with an earn-out from the sale of the
Company's lithotripsy partnerships which was recorded in fiscal 1999
(approximately $0.4 million).

Contract services revenues increased approximately 21.3% from approximately
$61.9 million for the nine months ended March 31, 1999, to approximately $75.1
million for the nine months ended March 31, 2000. This increase was due
primarily to the acquisitions and opened Fixed Facilities discussed above
(approximately $3.4 million) and an increase in the Company's existing business
(approximately $9.8 million). The increase in existing business was

                                       20
<PAGE>

due to (i) the addition of four Mobile Facilities and (ii) higher utilization
(approximately 14%) at the Company's existing mobile customer base, offset by a
decline in reimbursement from customers, primarily hospitals (approximately 2%).

Contract services revenues, primarily earned by its Mobile Facilities,
represented approximately 54% of total revenues for the nine months ended March
31, 2000. Each year approximately one-quarter to one-third of the contract
services agreements are subject to renewal. It is expected that some high volume
customer accounts will elect not to renew their agreements and instead will
purchase or lease their own diagnostic imaging equipment and some customers may
choose an alternative services provider. In the past where agreements have not
been renewed, the Company has been able to obtain replacement customer accounts.
While some replacement accounts have initially been smaller than the lost
accounts, such replacement accounts revenues have generally increased over the
term of the agreement. The non-renewal of a single customer agreement would not
have a material impact on the Company's contract services revenues; however,
non-renewal of several agreements could have a material impact on contract
services revenues.

In addition, the Company's contract services revenues with regard to its Mobile
Facilities in certain markets depend in part on some customer accounts with high
volume. If the future reimbursement levels of such customers were to decline or
cease or if such customers were to become financially insolvent and if such
agreements were not replaced with new accounts or with the expansion of services
on existing accounts, the Company's contract services revenues would be
adversely affected.

Patient services revenues increased approximately 18.7% from approximately $53.6
million for the nine months ended March 31, 1999, to approximately $63.6 million
for the nine months ended March 31, 2000. This increase was due primarily to the
acquisitions and opened Fixed Facilities discussed above (approximately $8.2
million) and an increase in revenues at existing facilities (approximately $1.9
million), offset by reduced revenues from the closure of the Open MRI Fixed
Facility discussed above (approximately $0.1 million). The increase at existing
facilities was due to higher utilization (approximately 10%), partially offset
by a decline in reimbursement from third party payors (approximately 3%).

Management believes that any future increases in revenues at existing facilities
can only be achieved by higher utilization and not by increases in procedure
prices; however, slower start-ups of new operations, excess capacity of
diagnostic imaging equipment, increased competition, and the expansion of
managed care may impact utilization and make it difficult for the Company to
achieve revenue increases in the future, absent the execution of provider
agreements with managed care companies and other payors, and the execution of
the Company's business strategy, particularly acquisitions. The Company's
operations are principally dependent on its ability (either directly or
indirectly through its hospital customers) to attract referrals from physicians
and other health care providers representing a variety of specialties. The
Company's eligibility to provide service in response to a referral is often
dependent on the existence of a contractual arrangement with the referred
patient's insurance carrier (primarily if the insurance is provided by a managed
care organization). Managed care contracting has become very competitive and
reimbursement schedules are at or below Medicare reimbursement levels, and a
significant decline in referrals could have a material impact on the Company's
revenues.

COSTS OF OPERATIONS: Costs of operations increased approximately 18.9% from
approximately $95.3 million for the nine months ended March 31, 1999, to
approximately $113.3 million for the nine months ended March 31, 2000. This
increase was due primarily to additional costs related to the acquisitions
and opened Fixed Facilities discussed above (approximately $11.1 million) and
at existing facilities (approximately $7.2 million), offset by reduced
expenses for the closed Open MRI Fixed Facility discussed above
(approximately $0.3 million).

Costs of operations, as a percentage of total revenues, remained at
approximately 81.0% for the nine months ended March 31, 2000 and 1999,
respectively. The Company is continuing its effort to improve operating
efficiencies through cost reduction initiatives commenced in the quarter ended
March 31, 2000.

CORPORATE OPERATING EXPENSES: Corporate operating expenses increased
approximately 9.3%, from approximately $7.5 million for the nine months ended
March 31, 1999, to approximately $8.2 million for the nine months ended March
31, 2000. This increase was due primarily to additional information systems
costs, offset by a

                                       21
<PAGE>

decrease in travel, legal and consulting costs. Corporate operating expenses, as
a percentage of total revenues, decreased from approximately 6.4% for the nine
months ended March 31, 1999, to approximately 5.9% for the nine months ended
March 31, 2000.

INTEREST EXPENSE, NET: Interest expense, net increased approximately 26.2% from
approximately $10.7 million for the nine months ended March 31, 1999, to
approximately $13.5 million for the nine months ended March 31, 2000. This
increase was due primarily to additional debt related to (i) the acquisitions
discussed above, (ii) the buy-out of operating leases discussed above, (iii)
higher interest rates on the Company's floating rate debt and (iv) the Company
upgrading its existing diagnostic imaging equipment, offset by reduced interest
as a result of amortization of long-term debt.

PROVISION FOR INCOME TAXES: Provision for income taxes increased from
approximately $0.3 million for the nine months ended March 31, 1999, to
approximately $0.9 million for the nine months ended March 31, 2000. The
effective tax rate increased to approximately 16% in 2000 from approximately 7%
in 1999 primarily as a result of the effects of benefits from the Company's net
operating loss carryforwards. At the beginning of each fiscal year, the Company
estimates its effective tax rate for the fiscal year. In addition, the Company
periodically reviews the effective tax rate in light of certain factors,
including actual operating income, acquisitions completed and new centers
opened, and the effects of benefits from the Company's net operating loss
carryforwards. This review may result in an increase or decrease in the
effective tax rate during the fiscal year.

INCOME PER COMMON AND CONVERTED PREFERRED SHARE: On a diluted basis, net income
per common and converted preferred share was $0.49 for the nine months ended
March 31, 2000, compared to net income per common and converted preferred share
of $0.45 for the same period in 1999. The increase in net income per common and
converted preferred share is the result of (i) increased income from company
operations and (ii) an increase in earnings from unconsolidated partnerships,
offset by (i) increased interest expense and (ii) an increase in provision for
income taxes.

THREE MONTHS ENDED MARCH  31, 2000 COMPARED TO MARCH 31, 1999

REVENUES: Revenues increased approximately 16.9% from approximately $40.8
million for the three months ended March 31, 1999, to approximately $47.7
million for the three months ended March 31, 2000. This increase was due
primarily to the acquisitions and opened Fixed Facilities discussed above
(approximately $4.3 million) and an increase in contract services and patient
services revenues (approximately $2.9 million) at existing facilities, offset by
a decrease in other revenues (approximately $0.3 million).

Contract services revenues increased approximately 18.3% from approximately
$21.8 million for the three months ended March 31, 1999, to approximately $25.8
million for the three months ended March 31, 2000. This increase was due
primarily to the acquisitions and opened Fixed Facilities discussed above
(approximately $1.2 million) and to an increase in the Company's existing
business (approximately $2.8 million). The increase in existing business was due
to (i) the addition of four Mobile Facilities and (ii) higher utilization
(approximately 14%) at the Company's existing mobile customer base, offset by a
decline in reimbursement from customers, primarily hospitals (approximately 2%).

Patient services revenues increased approximately 17.9% from approximately $18.4
million for the three months ended March 31, 1999, to approximately $21.7
million for the three months ended March 31, 2000. This increase was due
primarily to the acquisitions and opened Fixed Facilities discussed above
(approximately $3.2 million) and an increase in revenues at existing facilities
(approximately $0.3 million), offset by reduced revenues from the closure of the
Open MRI Fixed Facility discussed above (approximately $0.1 million). The
increase at existing facilities was due to higher utilization (approximately
10%), partially offset by a decline in reimbursement from third party payors
(approximately 2%).

COSTS OF OPERATIONS: Costs of operations increased approximately 11.5% from
approximately $33.8 million for the three months ended March 31, 1999, to
approximately $37.7 million for the three months ended March 31, 2000. This
increase was due primarily to additional costs related to the acquisitions and
opened Fixed Facilities

                                       22
<PAGE>

discussed above (approximately $4.1 million), offset by reduced expenses at
existing facilities (approximately $0.2 million).

Costs of operations, as a percentage of total revenues, decreased from
approximately 82.9% for the three months ended March 31, 1999, to approximately
79.1% for the three months ended March 31, 2000. The percentage decrease is due
primarily to reductions in diagnostic imaging equipment maintenance, medical
supplies and travel, offset by higher salaries and benefits at existing
facilities and the acquisitions and opened Fixed Facilities discussed above.

CORPORATE OPERATING EXPENSES: Corporate operating expenses decreased
approximately 3.4%, from approximately $2.9 million for the three months
ended March 31, 1999, to approximately $2.8 million for the three months
ended March 31, 2000. This decrease was due primarily to a reduction in
travel, legal and consulting costs, offset by additional information systems
costs. Corporate operating expenses, as a percentage of total revenues,
decreased from approximately 7.0% for the three months ended March 31, 1999,
to approximately 5.8% for the three months ended March 31, 2000.

INTEREST EXPENSE, NET: Interest expense, net increased approximately 40.5% from
approximately $3.7 million for the three months ended March 31, 1999, to
approximately $5.2 million for the three months ended March 31, 2000. This
increase was due primarily to additional debt related to (i) the acquisitions
discussed above, (ii) the buy-out of operating leases discussed above, (iii)
higher interest rates on the Company's floating rate debt and (iv) the Company
upgrading its existing diagnostic imaging equipment, offset by reduced interest
as a result of amortization of long-term debt.

PROVISION FOR INCOME TAXES: Provision for income taxes increased from
approximately $0.1 million for the three months ended March 31, 1999, to
approximately $0.2 million for the three months ended March 31, 2000. The
effective tax rate remained at approximately 10% in 2000 and 1999, primarily as
a result of the effects of benefits from the Company's net operating loss
carryforwards. At the beginning of each fiscal year, the Company estimates its
effective tax rate for the fiscal year. In addition, the Company periodically
reviews the effective tax rate in light of certain factors, including actual
operating income, acquisitions completed and new centers opened, and the effects
of benefits from the Company's net operating loss carryforwards. This review may
result in an increase or decrease in the effective tax rate during the fiscal
year.

INCOME PER COMMON AND CONVERTED PREFERRED SHARE: On a diluted basis, net income
per common and converted preferred share was $0.21 for the three months ended
March 31, 2000, compared to net income per common and converted preferred share
of $0.06 for the same period in 1999. The increase in net income per common and
converted preferred share is the result of (i) increased income from company
operations and (ii) an increase in earnings from unconsolidated partnerships,
offset by (i) increased interest expense and (ii) an increase in provision for
income taxes.

NEW PRONOUNCEMENTS

In fiscal 2001, the Company will be required to adopt Statement of Financial
Accounting Standards (SFAS) No. 133, "Accounting for Derivatives, Instruments
and Hedging Activities", as deferred and amended by SFAS No. 137. The Company
believes the adoption of this standard will not have a material impact on the
Company's financial condition or results of operations.

YEAR 2000 ISSUE

IMPACT OF YEAR 2000: The Year 2000 Issue exists because many computer systems
and applications currently use two-digit date fields to designate a year. As the
century date occurred, computer programs, computers and embedded microprocessors
controlling equipment with date-sensitive systems might have recognized Year
2000 as 1900 or not at all. This inability to recognize or properly treat Year
2000 might have resulted in computer system failures or miscalculations of
critical financial and operational information as well as failures of equipment
controlling date-sensitive microprocessors. In addition, miscalculations or
failures could have been caused by the fact that the Year 2000 is a leap year.

STATE OF READINESS: The Company started to formulate a plan to address the Year
2000 Issue in late 1995. The Company's primary focus was on its own internal
information technology systems, including all types of systems in use by the
Company in its operations, marketing, finance and human resources departments,
and to deal with the most critical systems first. The Company developed a Year
2000 Plan to address all of its Year 2000 Issues. The Company gave its Executive
Vice President and Chief Information Officer specific responsibility for
managing its Year 2000 Plan and a Year 2000 Committee was established to assist
in developing and implementing the Year 2000 Plan. As of April 30, 2000, the
Company had not experienced and does not expect to experience any material
disruptions to its operations due to Year 2000 Issues; however, no assurance can
be given that the Company has assessed, identified or corrected all Year 2000
Issues that may arise in the coming months.

The Company completed, prior to December 31, 1999, assessment, renovation,
testing and implementation of all of its internal information technology
systems, embedded microprocessors in its other equipment, facilities and
corporate and regional offices, and its diagnostic imaging equipment.

The Company also completed, prior to December 31, 1999, its assessment of the
potential Year 2000 problems with the information systems of its payors,
customers, business partners, landlords and vendors. As part of the Company's
Year 2000 Plan, it requested readiness statements from any third parties whose
non-compliance could materially adversely affect the Company. As of April 30,
2000, the Company had not experienced any Year 2000 Issues with its payors,
customers, business partners, landlords, vendors and third parties.

PRIOR COST ESTIMATES TO ADDRESS YEAR 2000 ISSUES: The Company originally
estimated the cost of assessment, renovation, testing and implementation
would range from approximately $500,000 to $800,000, primarily related to
capital expenditures for the replacement of diagnostic imaging equipment. As
of April 30, 2000, the Company had incurred less than $250,000 in costs
relating to consultants, additional personnel, programming, new software and
hardware, software upgrades and travel expenses. The Company does not expect
to incur significant additional expenses for Year 2000 efforts, except for
the early replacement of a piece of non-compliant diagnostic imaging
equipment at a Fixed Facility, at a cost of approximately $400,000, in the
quarter ended March 31, 2000, which was scheduled for replacement in fiscal
2001. The Company's costs may increase if additional Year 2000 Issues arise
in the future.

RISKS TO THE COMPANY: Although the Company has completed the implementation of
its Year 2000 Plan and has not encountered any material Year 2000 Issues, there
are risks if its efforts did not address all uncertainties or that all
uncertainties have been properly identified. A failure by the Company in
remedying a Year 2000 Issue, or its failure to be, or the failure of its payors,
customers, business partners, landlords, vendors and other third parties to be,
Year 2000 compliant, could, in the worst-case scenario, cause a business
interruption which may materially adversely affect the Company's business,
financial condition and results of operations depending upon the extent and
duration of the business interruption.

CONTINGENCY PLANS: The Company implemented a contingency plan to address
unavoided or unavoidable Year 2000 risks with internal information technology
systems and with customers, vendors and other third parties but no assurance can
be given that such plan will address all risks that may actually arise.

ITEM 3. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

The Company's market risk exposure relates primarily to interest rates, where
the Company will periodically use interest rate swaps to hedge interest rates on
long-term debt under its Bank Financing. The Company does not engage in
activities using complex or highly leveraged instruments.

At March 31, 2000, the Company had outstanding long-term debt of approximately
$67.0 million which has floating rate terms. The Company also had outstanding an
interest rate swap, converting $37.5 million of its floating rate debt to fixed
rate debt. Since the majority of the Company's debt has historically been
fixed-rate debt, the impact of the interest rate swap has not been material on
the Company's weighted average interest rate.

             the Acquisition since they were not required by Item 7.
