ambulatory surgery facilities, four inpatient rehabilitation facilities, three
outpatient rehabilitation facilities, two comprehensive mental health hospitals,
two sub-acute care facilities, two acute care facilities, one long-term care
facility, one assisted living facility and one integrated delivery facility. The

     The Company's properties are generally leased pursuant to fixed term
operating leases expiring from 2004 to 2011 and provide for options to extend
the lease terms for at least ten years. The leases generally provide the
lessees, during the terms of the leases and for a short period of time following
expiration, with the right of first refusal to purchase the leased property on
the same terms and conditions as the Company may propose to a third party.
 
     Each lease generally requires the lessee to pay base rent, additional rent
commencing after the first year based either on either a set percentage increase
or on a percentage increase in the consumer price index, and all taxes
(including property taxes), maintenance and other operating costs associated
with the leased property.
 
NOTE 4.  MORTGAGE NOTES RECEIVABLE
 
     As of September 30, 1996, the Company had provided $21,491,573 in mortgage
financing for seven properties located in five states. The mortgage notes
receivable are secured by the real estate of five long-term care facilities, and
two ancillary hospital facilities which are operated by four healthcare
operators.
 
     The mortgage notes receivable require monthly installments of principal and
interest with final payment dates in or before 2010 and bear rates ranging from
9.5 percent to 13.0 percent at September 30, 1996. Substantially all the
mortgage notes provide that the interest be increased annually by either a set
rate or upon an increase in the consumer price index.
 
     The Company had no impaired mortgage notes receivable at September 30, 1996
or during the quarter then ended.

NOTE 6.  BANK CREDIT FACILITY
 
     On June 24, 1996, the Company completed an amendment and restatement of its
unsecured line of credit ("Bank Credit Facility") which provides for an increase
to $150 million from its previous principal amount of $100 million, an extension
of the term to June 24, 1999, from June 22, 1997, and an adjustment in the

$91,200,000 against the Bank Credit Facility for the purchase of real estate
properties and the funding of mortgage loans.
 
     Borrowing under the amended and restated Bank Credit Facility bears
interest at a rate chosen by the Company from either the Bank's base rate or the
Eurodollar rate plus a percentage rate ranging from 1.00 percent to 1.625
percent depending upon the Company's senior debt to consolidated total capital
ratio for the preceding fiscal quarter. In addition, the Company pays a
commitment fee of 0.20 percent to 0.25 percent per annum on the unused portion
of funds available for borrowing under the Bank Credit Facility. The commitment
fee percentage is based on the Company's senior debt to total capital ratio.
 
     The Bank Credit Facility contains certain representations, warranties and
financial and other covenants customary in such loan agreements.

in stockholders' equity and a decrease of $5,847,000 in the outstanding balance
of the Debentures. For the nine months ended September 30, 1996, a total of

                    MANAGEMENT'S DISCUSSION AND ANALYSIS OF
                 FINANCIAL CONDITION AND RESULTS OF OPERATIONS
 
RESULTS OF OPERATIONS
 
  Third Quarter 1996 Compared to Third Quarter 1995
 
     Net income for the three months ended September 30, 1996 increased 104.3%
to $4.7 million compared to $2.3 million for the three months ended September
30, 1995. Net income per share was $0.44 (primary) and $0.42 (diluted) at
September 30, 1996 as compared to $0.38 per share (primary and diluted) at
September 30, 1995.
 
     Total revenues for the quarter ended September 30, 1996 increased 42.6% to
$9.7 million, compared to $6.8 million for the third quarter of 1995. The
increase in revenues is primarily attributable to additional rental and mortgage
interest income from the acquisition and financing of properties subsequent to
September 30, 1995. Specifically, investments in properties increased from $212
million at September 30, 1995 to $300 million at September 30, 1996 and mortgage
loans increased from $16.4 million at September 30, 1995 to $21.5 million at
September 30, 1996.
 
     Total expenses for the quarter ended September 30, 1996 increased 11.1% to
$5.0 million from $4.5 million for the quarter ended September 30, 1995.
Interest expense increased 2% from $2.67 million for the quarter ended September
30, 1995 to $2.72 million for the quarter ended September 30, 1996 primarily due
to increased borrowings under the Company's Bank Credit Facility as well as
interest related to the Company's Mortgage Note Payable that was entered into in
June of 1996. The increase in interest expense was offset in part by a decrease
in interest expense in connection with the conversion of $23.5 million of the
Company's convertible debentures since September 30, 1995. Depreciation for the
quarter ended September 30, 1996 totaled $1.6 million increasing 33.3% over
depreciation of $1.2 million for the quarter ended September 30, 1995, primarily
due to the acquisition of properties subsequent to September 30, 1995.
 
  Nine Months Ended September 30, 1996 Compared to Nine Months Ended September
30, 1995
 
     Net income for the nine months ended September 30, 1996 increased 95.6% to
$13.5 million compared to $6.9 million for the nine months ended September 30,
1995. Net income per share was $1.28 (primary) and $1.27 (diluted) at September
30, 1996 as compared to $1.15 (primary and diluted) at September 30, 1995.
 
     Total revenues for the nine months ended September 30, 1996, increased
47.7% to $26.0 million, compared to the $17.6 million the Company reported for
the first nine months of 1995. The increase in revenues is primarily
attributable to additional rental and mortgage interest income from the
acquisition and financing of properties subsequent to September 30, 1995. In
addition, during the nine months ended September 30, 1996, the Company
recognized a gain of $193,672 from the sale of an ancillary hospital facility
located in Philadelphia, Pennsylvania.
 
     Total expenses for the 1996 nine month period increased 17.9% to $12.5
million from $10.6 million for the first nine months of 1995. Interest expense
increased $0.4 million or 6.5% to $6.6 million in the 1996 nine month period as
compared to $6.2 million in the 1995 nine month period. This increase is due
primarily to interest related to the Company's Mortgage Note Payable that was
entered into in June of 1996. Depreciation and amortization increased $1.3
million or 43.3% to $4.3 million for the nine month period ended September 30,
1996 from $3.0 million for the same period in 1995. Depreciation expense
increased as a result of the acquisition of additional properties subsequent to
September 30, 1995. General and administrative expenses for the nine months
ended September 30, 1996 totaled $1.2 million, increasing 9.1% or $0.1 million
over September 30, 1995 general and administrative expenses of $1.1 million. The
increase is due primarily to additional administrative and professional services
related to the additional investments in properties made since September 30,
1995.

LIQUIDITY AND CAPITAL RESOURCES
 
     On June 24, 1996, the Company completed an amendment and restatement of its
unsecured line of credit ("Bank Credit Facility") which provides for an increase
to $150 million from its previous principal amount of $100 million, an extension
of the term to June 24, 1999, from June 22, 1997, and an adjustment in the
determination of the interest rate. The Bank Credit Facility is agented by
NationsBank, National Association (South) ("NationsBank"), and is participated
in by a consortium of seven other banks. At September 30, 1996, the Company had
drawn $91,200,000 against the Bank Credit Facility for the purchase of real
estate properties and the funding of mortgage loans.
 
     Borrowings under the Bank Credit Facility bear interest at a rate chosen by
the Company from either the Bank's base rate or the Eurodollar rate plus a
percentage rate ranging from 1.00 percent to 1.625 percent depending upon the
Company's senior debt to consolidated total capital ratio for the preceding
fiscal quarter. In addition, the Company pays a commitment fee of either .20
percent or .25 percent per annum on the unused portion of funds available for
borrowing under the Bank Credit Facility. The commitment fee percentage is based
on the Company's senior debt to total capital ratio.
 
     The Bank Credit Facility contains certain representations, warranties and
financial and other covenants customary in such loan agreements.
 
     The Company's current intention is to utilize the Bank Credit Facility on a
short-term basis to finance future acquisitions and investments. The Company is
currently evaluating various alternatives for additional equity and debt
financing with which to finance those acquisitions and investments on a
long-term basis.
 
     On October 22, 1996, the Company declared a dividend of $0.46 per share to
the holders of common stock on November 1, 1996. The dividend will be paid in
cash on November 15, 1996. The dividend related to the quarter ended September
30, 1996.
