NOTE 3.    REAL ESTATE PROPERTIES

         As of June 30, 1997 the Company had investments in 66 leased real
estate properties totaling $387.1 million. These real estate properties consist
of and include seventeen ancillary hospital facilities, ten physician clinics,
six ambulatory surgery facilities, ten assisted living facilities, nine skilled
nursing facilities, five inpatient rehabilitation facilities, three outpatient
rehabilitation facilities, two comprehensive mental health hospitals, two
sub-acute care facilities and two integrated delivery facilities. The properties
are located in fifteen states and are leased to fifteen healthcare-related
entities or their subsidiaries pursuant to long-term leases. In addition, the
Company has invested approximately $36.4 million in eighteen development
projects at various stages of completion. The Company has remaining commitments
of approximately $62.9 million related to the aforementioned development
projects and expects all projects to be completed by the first quarter of 1998.

         The Company's properties are generally leased pursuant to fixed term
operating leases expiring principally from 2004 to 2012 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 a set percentage increase
or on a percentage increase in the consumer price index, all taxes (including
property taxes), maintenance, and other operating costs associated with the
leased property.

NOTE 4.    MORTGAGE NOTES RECEIVABLE

         As of June 30, 1997, the Company had provided $88.1 million in mortgage
financing for 34 properties located in thirteen states. The mortgage notes
receivable are secured by the real estate of seventeen skilled nursing
facilities, fourteen assisted living facilities, two acute-care hospitals, and
one ancillary hospital facility which are operated by 23 healthcare operators.

         Twelve of the facilities are under construction, and the Company has
committed a total of $60.9 million in construction and term loans for these
projects. As of June 30, 1997, the Company had advanced a total of $21.7 million
toward these financing commitments. The Company expects to disburse the
remainder of the committed funds during 1997.

         The mortgage notes receivable for completed projects ("Permanent
Loans") require monthly installments of principal and interest with final
payment dates in or before 2009 and bear rates ranging from 10.00 percent to
13.39 percent at June 30, 1997. Each Permanent Loan provides for an initial
interest rate to be increased annually by either a set rate or upon an increase
in the consumer price index. For those projects under construction, the notes
receivable typically bear interest at a floating rate and require monthly
payments of interest only. Upon completion of construction, the outstanding
principal balance is converted to a Permanent Loan.

         The Company had no impaired mortgage notes receivable at or during the
quarter ended June 30, 1997.

NOTE 5.    MORTGAGE NOTES PAYABLE

         The Company has a non-recourse mortgage note payable to a life
insurance company for a principal amount of $23.1 million ("$23.1 Million
Mortgage Note"). The $23.1 Million Mortgage Note bears interest at 8.5% and is
payable in monthly payments of principal and interest based on a 30 year
amortization with the remaining unpaid balance due in a balloon payment on May
26, 2026. The $23.1 Million Mortgage Note is collateralized by an ancillary
hospital facility purchased in January 1996 for $30 million.

         The Company has a non-recourse mortgage note payable to a bank for a
principal amount of $17.0 million ("$17.0 Million Mortgage Note"). The $17.0
Million Mortgage Note bears interest at 50 basis points in excess of the prime
rate, as such rate fluctuates from time to time, and is payable in monthly
payments of principal and interest based on a 25 year amortization with the
unpaid balance due in a balloon payment on June 20, 2000. The interest rate as
of June 30, 1997 was 9.0%. The $17.0 Million Mortgage Note is collateralized by
six skilled nursing facilities purchased in June 1997 for $23.8 million.

NOTE 6.    BANK CREDIT FACILITY

         The Company has a $170 million unsecured line of credit ("Bank Credit
Facility") which is participated in by a consortium of eight banks. At June 30,
1997, the Company had drawn $107.7 million against the Bank Credit Facility for
the purchase of real estate properties and the funding of mortgage loans. The
Bank Credit Facility is available until June 24, 2000.

NOTE 7.    CONVERTIBLE SUBORDINATED DEBENTURES

         As of June 30, 1997 the Company had $7,098,000 aggregate principal
amount of 10.50% convertible subordinated debentures (the "10.5% Debentures")
outstanding. The 10.5% Debentures are due on April 1, 2002 and interest is
payable semiannually on April 1 and October 1 of each year. During the quarter
ended June 30, 1997, a total of $9,902,000 of principal amount of the 10.5%
Debentures was converted into 614,077 shares of common stock of the Company at
the conversion price of $16.125 per share.

         As of June 30, 1997, the Company had $74,750,000 aggregate principal
amount of 6.55% convertible subordinated debentures (the "6.55% Debentures").
The 6.55% Debentures are due on March 14, 2002 and were issued at a price of
$903 per $1,000 principal amount at maturity, which represents an original issue
discount of 9.70% from the principal amount thereof which is payable at
maturity. Interest on the 6.55% Debentures is payable March 14 and September 14
in each year, commencing September 14, 1997. Such rate of interest and accrual
of original issue discount represent a yield to maturity of 9.00% per annum
(computed on a semiannual bond equivalent basis).

         The 6.55% Debentures are convertible into common stock of the Company
at any time before maturity at an initial conversion ratio of 39.4754 shares of
common stock for each $1,000 principal amount of 6.55% Debentures, subject to
adjustment in certain events. As of June 30, 1997, there had been no conversions
of the 6.55% Debentures.

financing. As of June 30, 1997, the Company had funded approximately $58.0
million towards these commitments with the balance of $102.2 million expected to
be funded over the next nine months.

         During May 1997, the Company provided a letter of credit in the amount
of $2,869,800 to a third party lender in connection with a project under

NOTE 10.   SUBSEQUENT EVENTS

         On July 23, 1997, the Company acquired a integrated delivery facility
located in Chicago Heights, Illinois. The property's acquisition price of $9.0
million was funded with a draw against the Bank Credit Facility. The property is
leased to a healthcare- related entity pursuant to a long-term operating lease.

         During July 1997, the Company raised net proceeds of $3.6 million with
the sale of an additional 155,400 shares of common stock. The proceeds were used
to reduce the Bank Credit Facility. Also during July the Company filed a
registration statement ("Shelf Registration") with the Securities and Exchange
Commission to enable the Company to offer up to an aggregate of $500,000,000 in
debt securities, preferred stock, common stock, and warrants to purchase any of
the foregoing securities at prices and terms to be determined at the time of
sale.

         On July 18, 1997, the Company declared a dividend of $0.475 per share
to the holders of common stock on August 1, 1997. The dividend will be paid in
cash on August 15, 1997. The dividend related to the quarter ended June 30,
1997.

         For the period from July 1 through August 10, 1997, a total of
$2,074,000 of principal amount of 10.5% Debentures has been converted into
shares of common stock of the Company at the conversion price of $16.125 per
share. The conversions resulted in an increase of 128,620 shares outstanding of
common stock of the Company.

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


RESULTS OF OPERATIONS

SECOND QUARTER 1997 COMPARED TO SECOND QUARTER 1996

         For the quarter ended June 30, 1997 the Company reported net income of
$6.4 million or $0.43 per common share, compared to $4.6 million, or $0.42 per
common share at June 30, 1996.

         Revenues for the quarter ended June 30, 1997 totaled $12.9 million, an
increase of $4.0 million over June 30, 1996 revenues of $8.9 million. The
increase in revenues is primarily attributable to additional rental and mortgage
interest income from investments made since June 30, 1996. Specifically, the
Company's investments in real estate increased by approximately $105.2 million
to $387.1 million at June 30, 1997 from $281.9 million at June 30, 1996. The
Company's investments in mortgage loans increased $60.5 million to $90.9 million
at June 30, 1997 from $30.4 million at June 30, 1996.

         Interest expense for the quarter ended June 30, 1997 totaled $3.4
million, an increase of $1.1 million over June 30, 1996 interest expense of $2.3
million. The increase is primarily due to a full quarter's interest related to
the $23.3 Million Mortgage Note entered into in June 1996 and a half month's
additional interest related to the $17.0 Million Mortgage Note. The Company also
incurred a full quarter's additional interest on the 6.55% Debentures issued in
March 1997 which was slightly offset by the decrease in interest accrued on the
10.5% Debentures due to conversions into the Company's common stock.

         Depreciation for the quarter ended June 30, 1997 totaled $2.1 million
an increase of $0.6 million over June 30, 1996 depreciation of $1.5 million.
This is primarily due to the acquisition of real estate properties subsequent to
June 30, 1996.

SIX MONTHS ENDED JUNE 30, 1997 COMPARED TO SIX MONTHS ENDED JUNE 30, 1996

         For the six months ended June 30, 1997 the Company reported net income
of $12.7 million or $0.86 per common share, compared to $8.7 million, or $0.84
per common share at June 30, 1996.

         Revenues for the six months ended June 30, 1997 totaled $24.2 million,
increasing $7.9 million over June 30, 1996 revenues of $16.3 million. The
increase in revenues is primarily attributable to additional rental and mortgage
interest income from investments made subsequent to June 30, 1996.

         Interest expense for the six months ended June 30, 1997 totaled $6.0
million, an increase of $2.1 million over June 30, 1996 interest expense of $3.9
million. The increase was due to five months' additional interest related to the
$23.3 Million Mortgage Note entered into in June 1996 and a half month's
additional interest related to the $17.0 Million Mortgage Note entered into in
June of 1997. The Company also incurred an

additional three months' interest on the 6.55% Debentures issued in March 1997
which was slightly offset by the decrease in interest accrued on the 10.5%
Debentures due to conversions into the Company's common stock. Interest expense
for the six months ended June 30, 1997 was also greater than interest expense
for the same period in 1996 due to additional amounts outstanding under the Bank
Credit Facility.

         Depreciation for the six months ended June 30, 1997 totaled $3.8
million an increase of $1.1 million over June 30, 1996 depreciation of $2.7
million. This is primarily due to the acquisition of real estate properties
subsequent to June 30, 1996.

LIQUIDITY AND CAPITAL RESOURCES

         During June 1997, the Company raised net proceeds of $29.9 million
with the sale of 1.3 million shares of common stock at $24.25. During July 1997,
the Underwriter exercised its 30-day option to purchase an additional 155,400
shares for net proceeds of $3.6 million, which was used to reduce the Bank
Credit Facility. Also during July the Company filed a registration statement
("Shelf Registration") with the Securities and Exchange Commission to enable the
Company to offer up to an aggregate of $500,000,000 in debt securities,
preferred stock, common stock, and warrants to purchase any of the foregoing
securities at prices and terms to be determined at the time of sale.

         At June 30, 1997, the outstanding balance of the Bank Credit Facility
was $107.7 million, the entire balance of which was used for the acquisition of
real estate and the funding of mortgage loans. Due to acquisitions of real
estate and the funding of development projects subsequent to June 30, 1997, the
balance of the Bank Credit Facility as of August 10, 1997 was $125.1 million.

         The Company's current intention is to utilize the Bank Credit
Facility on a short-term basis to finance future investments in property
acquisitions and mortgage financing. The Company is currently evaluating various
alternatives for additional equity and debt financing with which to finance
those investments on a long-term basis.

         On July 18, 1997, the Company declared a dividend of $0.475 per share
to the holders of common stock on August 1, 1997. The dividend will be paid in
cash on August 15, 1997. The dividend related to the quarter ended June 30,
1997.

         The Company has a dividend reinvestment and stock purchase plan
("Plan") under which participants can automatically reinvest all or a portion of
cash dividends in shares of the Company's common stock and can make voluntary
cash payments for additional shares. Under the Plan, the Company had received
$66,865 for the six months ended June 30, 1997 in exchange for 2,908 shares of
common stock.

COMMITMENTS

         The Company has committed a total of approximately $160.2 million
towards the acquisition and construction of real estate properties and providing
mortgage financing. As of June 30, 1997, the Company had funded approximately
$58.0 million towards these commitments, with the balance of $102.2 million
expected to be funded during the next twelve months. Financing for these
commitments may be provided by funds from

operations, borrowings under the Bank Credit Facility or private or public
offerings of debt or equity.

         During May 1997, the Company provided a letter of credit in the amount
of $2,869,800 to a third party lender in connection with a project under
development. The lender may only draw on the letter of credit in the event that
the developer defaults on the loan. The letter of credit expires in the earlier
of one year or with payoff of the construction loan.
