                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
                                   (Unaudited)

NOTE 1 - Basis of Presentation

The accompanying unaudited consolidated financial statements have been prepared
in accordance with generally accepted accounting principles for interim
financial information and with 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. In the opinion of management of HCR Manor Care, Inc. (HCR
Manor Care or the Company), the interim data includes all adjustments necessary

</TABLE>

In Manor Care's planned spin-off, the employees did not receive lump-sum
severance payments upon termination but receive their severance as biweekly
payments through 1999. In the HCR and Manor Care merger, 531 employees received
termination notices and at March 31, 1999 all but 25 employees have left the
Company. Many employees who left the Company continue to be paid 




                                       6
<PAGE>   7


severance payments on a biweekly basis through 1999. The non-cash charge for
amortization primarily related to certain Manor Care software applications which
are being used until the transition to HCR applications. The carrying value of
the software is being amortized over its remaining estimated useful life ranging
from six to nine months. Certain general and administrative costs of $2.3
million represented salaries and benefits for employees performing duplicate
services in Toledo or Gaithersburg.

NOTE 4 - Subsequent Events

During the fourth quarter of 1998, the Company formed a strategic alliance with
Alternative Living Services (Alterra). The key provisions of the alliance
include four components: 1) sale of 28 centers to Alterra for approximately $200
million in cash, 2) creation of a joint venture to develop and construct up to
$500 million of specialized assisted living residences in the Company's core
markets over the next three to five years, 3) enter into a joint marketing and
branding relationship with Alterra and 4) HCR Manor Care will form a new company
to provide a variety of ancillary services to Alterra's resident population.
During April 1999, the Company completed the sale of three centers to Alterra
for approximately $17 million and entered into an ancillary services agreement
with Alterra. The remaining asset sales and creation of the development joint
venture are expected to be completed in the second quarter of 1999.

In May 1999 the Company exercised the purchase option and simultaneously sold
the Manor Care headquarters in Gaithersburg, Maryland with a net cash receipt of
approximately $25 million. The gain on the sale will be recorded in the second
quarter.

On May 4, 1999 the Board of Directors of HCR Manor Care authorized the Company
to purchase up to $200 million of its common stock through December 31, 2000.
The shares may be used for internal stock option and 401(k) match programs and
for other uses, such as possible future acquisitions.

NOTE 5 - New Accounting Pronouncements

In June 1998, the FASB issued Statement No. 133, "Accounting for Derivative
Instruments and Hedging Activities" (FAS 133), which is effective January 1,
2000. This Statement permits early adoption as of the beginning of any fiscal
quarter after its issuance. This Statement requires the Company to recognize all
derivatives on the balance sheet at fair value. Management has not determined
when it will adopt this Statement nor has it determined the impact of adoption.

Item 2. Management's Discussion and Analysis of Financial Condition and Results
        of Operations

RESULTS OF OPERATIONS

Revenues for the three months ended March 31, 1999 decreased $19.3 million or 4%
to $531.8 million as compared to the same period in 1998. Revenues from skilled
nursing and assisted living facilities decreased $19.7 million or 4% due to
decreases in rates ($24.1 million) and occupancy ($21.0 million) partially
offset by an increase in capacity ($25.4 million). The decline in rates was
primarily attributable to transitioning the former HCR long-term care facilities
onto the new Medicare Prospective Payment System (PPS). The occupancy levels for
all facilities including start-ups were 89% for the three months ended March 31,
1998 compared to 86% for the same period in 1999. The occupancy for the
Company's skilled nursing facilities declined from 89% in the first quarter of
1998 to 87% in the first quarter of 1999 reflecting the impact of transitioning
onto the Medicare PPS and a decline in the private pay mix over the last year.
The growth in bed capacity between the first quarter of 1999 and 1998 was due to
the opening of 28 assisted living and 3 skilled facilities in the last nine
months of 1998 and first three months of 1999.

The quality mix of revenue from Medicare, private pay and insured patients
related to skilled nursing and assisted living facilities and rehabilitation
operations decreased from 73% for the three months ended March 31, 1998 to 68%
for the same period in 1999. This decline was a result of the decrease in
Medicare rates and census due to the Medicare PPS and a decline in the private
pay mix.

Operating expenses for the three months ended March 31, 1999 decreased $14.8
million or 3% to $408.5 million from the comparable period in 1998. Operating
expenses from skilled nursing and assisted living facilities decreased $11.6
million or 3%. By excluding the effect of start-up facilities in the first
quarter of 1999 and 1998, operating expenses decreased $19.2 million which was
primarily attributable to the decline in ancillary costs as a result of the
Medicare PPS.

General and administrative expense decreased $6.5 million for the three months
ended March 31, 1999 as compared to the same period in 1998 as a result of
synergies obtained from combining HCR and Manor Care and reclassifying $2.3
million of duplicate costs to the provision for the restructuring charge and
other related charges, as explained below. Depreciation and amortization
remained constant between the first quarter of 1999 and 1998 due to additional
depreciation for completion of new construction projects and renovations in the
past year offset by a decline in the amortization of Manor Care's computer
software and the Company's goodwill related to the write down of assets in 1998.

</TABLE>

In Manor Care's planned spin-off, the employees did not receive lump-sum
severance payments upon termination but receive their severance as biweekly
payments through 1999. In the HCR and Manor Care merger, 531 employees received
termination notices and at March 31, 1999 all but 25 employees have left the
Company. Many employees who left the Company continue to be paid severance
payments on a biweekly basis through 1999. The non-cash charge for amortization
primarily related to certain Manor Care software applications which are being
used until the transition to HCR applications. The carrying value of the
software is being amortized over its remaining estimated useful life ranging
from six to nine months. Certain general and administrative costs of $2.3
million represented salaries and benefits for employees performing duplicate
services in Toledo or Gaithersburg.

Interest expense increased $2.3 million for the three months ended March 31,
1999 as compared to the same period in 1998 due to an increase in debt
outstanding under bank credit facilities. Dividend income increased $4.4 million
between the first quarter of 1999 and 1998 due to the dividend recorded on the
Company's ownership of Series G Cumulative Convertible Preferred Stock of
Genesis Health Ventures, Inc (Genesis). The decrease in equity earnings of
affiliated companies was attributable to a decline in earnings of the pharmacy
partnership due to a reduction in prices as a result of the Medicare PPS.
Interest income and other decreased between the first quarter of 1999 and 1998
primarily due to a decline in rental income from Manor Care's corporate office
buildings that were sold during 1998.

NEW ACCOUNTING PRONOUNCEMENTS

In June 1998, the FASB issued Statement No. 133, "Accounting for Derivative
Instruments and Hedging Activities" (FAS 133), which is effective January 1,
2000. This Statement permits early adoption as of the beginning of any fiscal
quarter after its issuance. This Statement requires the Company to recognize all
derivatives on the balance sheet at fair value. Management has not determined
when it will adopt this Statement nor has it determined the impact of adoption.

LIQUIDITY AND CAPITAL RESOURCES

During the first three months of 1999, the Company satisfied its cash
requirements from a combination of cash generated from operating activities and
borrowings under bank credit agreements. The Company used the cash principally
for capital expenditures. At March 31, 1999, the Company maintained $14.4
million in cash and cash equivalents, of which $11.0 million was invested in
short-term investments. Expenditures for property and equipment during the three
months ended March 31,1999 consisted of $29.0 million for construction of new
facilities and $22.8 million for renovation and maintenance of existing
facilities.

At March 31, 1999, outstanding borrowings aggregated $729 million under the bank
credit agreements. After consideration of usage for letters of credit, the
remaining credit availability under the agreements totaled $62.7 million.

During the fourth quarter of 1998, the Company formed a strategic alliance with
Alternative Living Services (Alterra). Two of the key provisions of the alliance
include the sale of 28 centers to Alterra for approximately $200 million in cash
and the creation of a joint venture to develop and construct up to $500 million
of specialized assisted living residences in the Company's core markets over the
next three to five years. During April 1999, the Company completed the sale of 3
centers to Alterra for approximately $17 million. The remaining asset sales and
creation of the development joint venture are expected to be completed in the
second quarter of 1999.

In May 1999 the Company exercised the purchase option and simultaneously sold
the Manor Care headquarters in Gaithersburg, Maryland with a net cash receipt of
approximately $25 million. On May 4, 1999 the Board of Directors of HCR Manor
Care authorized the Company to purchase up to $200 million of its common stock
through December 31, 2000. The shares may be used for internal stock option and
401(k) match programs and for other uses, such as possible future acquisitions.

The Company has cash flow commitments related to the HCR and Manor Care merger
restructuring plan that will require approximately $18 million in the remainder
of 1999, primarily for employee benefits.

HCR Manor Care believes that its cash flow from operations will be sufficient to
cover debt payments, future capital expenditures and operating needs. It is
likely that the Company will pursue growth from acquisitions, partnerships and
other ventures which would be funded from excess cash from operations, credit
available under the bank credit agreement and other financing arrangements that
are normally available in the marketplace.

YEAR 2000

The Year 2000 issue is the result of computer programs being written using two
digits rather than four digits to define the year. Any of the HCR Manor Care
computer software and hardware that are date sensitive and all of our embedded
chip devices could recognize a two digit date of `00' as `1900' rather than
`2000'. This could result in system failures and miscalculations causing
disruptions to our operations.

In 1995, HCR began an evaluation and upgrade to all of its technical
infrastructure including hardware, operating systems and business applications.
With the completion of that upgrade 




                                       10
<PAGE>   11


process, the Company will have in place, a complete package of technical
solutions that properly utilize dates beyond December 31, 1999. The estimated
costs of this package are expected to be $35 million. Most of these costs will
be capitalized and amortized over a five to twelve year period. Since inception
of the project, the Company has incurred approximately $21.7 million ($2.7
million expensed and $19.0 million capitalized) as of March 31, 1999. The
Company has completed the technical solution definition and is 75% complete with
the implementation. All computer hardware, software and operating system
upgrades are expected to be in place by the end of the third quarter of 1999. It
has not been necessary to accelerate our original implementation plan due to the
Year 2000 issue.

To insure that our embedded chip devices, vendor and supplier interfaces are
also Year 2000 compliant, the Company has put into place an assessment,
remediation, testing, implementation and contingency plan for all products,
services and relationships that do not meet our Year 2000 compliance standards.
The Company expects all phases along with the contingency plan to be completed
by the end of the third quarter of 1999 with internal resources. The Company has
queried our significant suppliers and at this point, based on their
representations, the Company does not believe that Year 2000 presents a material
exposure as it relates to our embedded chip devices, system interfaces,
significant suppliers or vendors. The Company believes today that the most
likely worst case scenario, if it occurred, would involve temporary disruptions
in delivery of medical and other supplies and temporary disruptions in payments,
especially payments from Medicare and other government programs. If the federal
and state healthcare reimbursement agencies or their intermediaries were to fail
to implement Year 2000 compliant technologies before December 31, 1999, a
temporary cash flow disruption could result. Those agencies and intermediaries
have Year 2000 plans in place and the Company continues to monitor the status of
those projects. However, all of the governmental agencies have stated that
interim payment procedures would be implemented if their Year 2000 solutions are
not in place by January 1, 2000.

The foregoing assessment is based on information currently available to the
Company. The Company will revise its assessment as it implements its Year 2000
strategy. The Company's Year 2000 compliance program is an ongoing process and
the risk assessments and estimates of costs and completion dates for various
phases of the program are subject to change. The cost of the Year 2000 program
and the dates on which the Company believes the phases of the program will be
completed are based on management's best estimates, which were derived using
numerous assumptions of future events. Factors that could cause such changes
include availability of qualified personnel and consultants, the actions of
third parties and material changes in governmental regulations. There can be no
guarantee that these estimates will be achieved and actual results could differ
materially from those anticipated.

                           PART II. OTHER INFORMATION

Item 1.  Legal Proceedings.

         On May 7, 1999 Genesis Health Ventures ("Genesis") filed suit in the
         United States District Court for the District of Delaware (the
         "Delaware Action") against the Company, Manor Care, Inc., Paul A. 
         Ormond and Stewart Bainum, Jr. Manor Care, Inc. has been a 
         wholly-owned subsidiary of the company since September 25, 1998. 
         Mr. Ormond is President and Chief Executive Officer of the Company and
         Mr. Bainum is Chairman of the Board of Directors of the Company and 
         formerly was Chairman of the Board, President and Chief Executive 
         Officer of Manor Care, Inc. The complaint alleges that the defendants 
         fraudulently induced Genesis to acquire, in August, 1998, all of the 
         outstanding stock of Vitalink Pharmacy Services, Inc. ("Vitalink") and
         that such alleged conduct constituted violations of Section 10(b) of 
         the Securities and Exchange Act of 1934, common law fraudulent 
         misrepresentation, negligent misrepresentation and breach of contract.
         The suit seeks compensatory and punitive damages in excess of $100 
         million and preliminary and permanent injunctive relief enforcing a 
         covenant not to compete allegedly applicable to the Company. The
         Company believes that the material allegations of the complaint are
         untrue and that it has substantial defenses to the factual and legal 
         assertions in the complaint. The Company intends to vigorously defend 
         the lawsuit. Although the ultimate outcome of the case is uncertain, 
         it is not likely to have a material adverse effect on the financial 
         condition of the Company.

         In addition to the Delaware Action, on May 7, 1999 Vitalink instituted
         a lawsuit in the Circuit Court for Baltimore City, Maryland (the
         "Maryland Action") against the Company, Manor Care, Inc. and ManorCare 
         Health Services, Inc. (collectively, the "Maryland Defendants") seeking
         damages, preliminary and permanent injunctive relief and a declaratory
         judgment related to allegations that the Maryland Defendants have 
         improperly sought to terminate certain pharmacy related contracts 
         between Vitalink and ManorCare Health Services, Inc. Vitalink has also
         purported to institute arbitration proceedings (the "Arbitration") 
         against the Maryland Defendants with the American Arbitration 
         Association, seeking substantially the same relief as sought in the
         Maryland Action with respect to one of pharmacy related contracts 
         at issue in the Maryland Action and also certain additional permanent
         relief with respect to that contract. On May 13, 1999, Vitalink and the
         Maryland Defendants agreed: (i) to consolidate the Maryland Action
         into the Arbitration; (ii) to dismiss the Maryland Action with 
         prejudice as to jurisdiction and without prejudice as to the merits; 
         (iii) to stay termination of the agreements at issue until a decision
         can be reached in the Arbitration; and (iv) that Vitalink shall not
         proceed on its claims for preliminary reief in the Maryland Action or 
         the Arbitration in view of the May 13, 1999 agreement. The Company
         believes that the material allegations in the Maryland Action and in 
         the demand for Arbitration are untrue and that it has substantial 
         factual and legal defenses to both the Maryland Action and the 
         Arbitration. The Company intends to vigorously defend the Maryland 
         Action and the Arbitration. Although the ultimate outcome of such 
         proceedings is uncertain, the outcome is not likely to have a material
         adverse effect on the financial condition of the Company.

         One or more subsidiaries or affiliates of Manor Care have been
         identified as potentially responsible parties (PRPs) in a variety of
         actions (the Actions) relating to waste disposal sites which allegedly
         are subject to remedial action under the Comprehensive Environmental
         Response Compensation Liability Act, as amended, 42 U.S.C. Sections
         9601 et seq. (CERCLA) and similar state laws. CERCLA imposes
         retroactive, strict joint and several liability on PRPs for the costs
         of hazardous waste clean-up. The Actions arise out of the alleged
         activities of Cenco, Incorporated and its subsidiary and affiliated
         companies (Cenco). Cenco was acquired in 1981 by a wholly owned
         subsidiary of Manor Care. The Actions allege that Cenco transported
         and/or generated hazardous substances that came to be located at the
         sites in question. The Company believes the waste disposal activities
         at issue occurred prior to the Manor Care subsidiary's acquisition of
         Cenco. Environmental proceedings such as the Actions may involve owners
         and/or operators of the hazardous waste site, multiple waste generators
         and multiple waste transportation disposal companies. Such proceedings
         involve efforts by governmental entities and/or private parties to
         allocate or recover site investigation and clean-up costs, which costs
         may be substantial. The potential liability exposure for currently
         pending environmental claims and litigation, without regard to
         insurance coverage, cannot be quantified with precision because of the
         inherent uncertainties of litigation in the Actions and the fact that
         the ultimate cost of the remedial actions for some of the waste
         disposal sites where Manor Care is alleged to be a potentially
         responsible party has not yet been quantified. Based upon its current
         assessment of the likely outcome of the Actions, the Company believes
         that the potential environmental liability exposure, after
         consideration of insurance coverage, is approximately $5 million.

         The Company is party to various other legal proceedings arising in the
         ordinary course of business. The Company does not believe the results
         of such proceedings, even if unfavorable to the Company, would have a
         material adverse effect on its financial position.

         On February 8, 1999, HCR Manor Care filed a Form 8-K for the

         the fourth quarter of 1998, the Company changed the accounting for its
         investment in In Home Health, Inc. from consolidation to the equity 
         method retroactive to January 1, 1998 and the Company elected to adopt
         Statement of Position 98-5, "Reporting on the Costs of Start-up 
         Activities," as of January 1, 1998.
