               HARBORSIDE HEALTHCARE CORPORATION AND SUBSIDIARIES
              NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS
                                  (Unaudited)

A. General

The accompanying unaudited condensed consolidated financial statements should be
read in conjunction with the consolidated financial statements and notes thereto
included in the Company's Annual Report or Form 10-K for the year ended December
31, 1997 and its subsequent filings on Forms S-4 and 8-K.  In the opinion of
management, the accompanying unaudited financial statements reflect all
adjustments (consisting of only normal recurring accruals)  necessary to present
fairly the Company's financial position as of September 30, 1998,  the results
of its operations for the three-month and nine-month periods ended September 30,
1997 and 1998 and its cash flows for the nine-month periods ended September 30,
1997 and 1998.  The results of operations for the three-month and nine-month
periods ended September 30, 1998 are not necessarily indicative of the results
which may be expected for the full year.  See "Management's Discussion and
Analysis of Financial Condition and Results of Operations" included elsewhere in
this report.

B.  Basis of Presentation

On April 15, 1998, Harborside Healthcare Corporation ("Harborside") entered into
a Merger Agreement with HH Acquisition Corp. ("MergerCo"), an entity organized
for the sole purpose of effecting a merger on behalf of Investcorp S.A., certain
of its affiliates and certain other international investors (the "New
Investors").  On August 11, 1998, MergerCo merged with and into Harborside, with
Harborside as the surviving corporation.  As a result of the transaction, and
pursuant to the Merger Agreement, the New Investors acquired approximately 91%
of the post-merger common stock of Harborside.  The remaining 9% of the common
stock was retained by existing shareholders, including management.  As a result
of the merger, Harborside shares have been de-listed from the New York Stock
Exchange.

The merger was approved by a majority of Harborside's shareholders at a
special meeting held on August 11, 1998.  Each share not retained by existing
shareholders was converted into $25 in cash, representing in the aggregate, cash
payments of approximately $184 million. Holders of outstanding stock options of
the Company converted the majority of their options into cash at $25 per
underlying share (less applicable exercise price and withholding taxes) with
aggregate payments of approximately $8 million.

In connection with the transaction and prior to the merger, the New Investors
made cash common equity contributions of $165 million to MergerCo, and MergerCo
obtained gross proceeds of $99.5 million through the issuance of 11% Senior
Subordinated Discount Notes ("Discount Notes") due 2008 and $40 million through
the issuance of 13.5% Exchangeable Preferred Stock ("Preferred Stock")
mandatorily redeemable in 2010. In connection with the merger, Harborside also
entered into a new $250 million secured credit facility with Chase Securities
Inc., as Arranger, Morgan Stanley Senior Funding, Inc. and BT Alex. Brown
Incorporated, as Co-Arrangers, Bankers Trust Company, as Documentation Agent,
Morgan Stanley Senior Funding, Inc., as Syndication Agent, The Chase Manhattan
Bank, as Administration Agent and the lenders named therein. In connection with
the merger, Harborside recorded in the third quarter a charge to income from
operations of $37 million ($29 million after taxes) for direct and other costs
related to the merger transaction. In connection with the merger and the related
refinancings, the Company exercised purchase options for seven facilities which
had been financed through synthetic leases.

E.  Equity

On April 15, 1998, the Company entered into a Merger Agreement with HH
Acquisition Corp.  ("MergerCo"), an entity organized for the sole purpose of
effecting a merger on behalf of Investcorp S.A., certain of its affiliates and
certain other international investors (collectively, the "New Investors").  On
August 11, 1998, MergerCo merged with and into the Company, with the Company as
the surviving corporation.  As a result of the merger, the New Investors
acquired approximately 91% of the post-merger common stock of the Company.
Certain pre-merger stockholders of the Company, including certain of the
Company's existing members of senior management, retained approximately 660,000
shares (or approximately 9%) of the Company's post-merger common stock.  Each
other share of the Company's pre-merger common stock was converted into $25 in
cash, representing aggregate cash payments of approximately $184 million.
Holders of outstanding stock options of the Company converted the majority of
their options into cash at $25 per underlying share less the applicable option
exercise price and withholding taxes, representing aggregate cash payments of
approximately $8 million.

In connection with the transaction and prior to the merger, the New Investors
made cash common equity contributions of $165 million to MergerCo, and MergerCo
obtained gross proceeds of $99.5 million through the issuance of 11% senior
subordinated discount notes due 2008 and $40 million through the issuance of
13.5% exchangeable preferred stock mandatorily redeemable 2010.  In connection
with the merger, the Company also entered into a new $250 million senior secured
credit facility with a group of banks.

F. Income taxes

expense for the nine months ended September 30, 1998  is as follows:

store" facilities increased from 91.6% during the third quarter of 1997 to 92.5%
during the third quarter of 1998.  The average occupancy rate at all of the
Company's facilities increased from 92.0% during the third quarter of 1997 to
92.4% during the third quarter of 1998.  The Company's quality mix of private,
Medicare and insurance revenues was 59.6% for the three months ended September
30, 1997 as compared to 56.4% in the same period of 1998. The decrease in the
quality mix percentage was primarily due to the effects of acquired facilities.

Facility Operating Expenses. Facility operating expenses increased by
$16,331,000, or 35.1%, from $46,556,000 in the third quarter of 1997 to
$62,887,000 in the third quarter of 1998. The operation of the Massachusetts
facilities accounted for $2,184,000 or 13.4% of this increase , the operation of
the Dayton, Ohio facilities accounted for $2,126,000 or 13.0% of this increase,
the operation of the Connecticut facilities accounted for $9,314,000 or 57.0% of
this increase, the operation of the North Toledo facilities accounted for
$2,451,000 or 15.0% of this increase, and the operation of the Rhode Island
facilities accounted for $2,850,000 or 17.5% of this increase. The operating
expenses of rehabilitation therapy services at non-affiliated long-term care
facilities decreased by $2,548,000 or 52.2%, from $4,877,000 in the third
quarter of 1997 to $2,329,000 in the third quarter of 1998.

General and Administrative; Service Charges Paid to Affiliate. General and
administrative expenses increased by $869,000, or 31.5% from $2,756,000 in the
third quarter of 1997 to $3,625,000 in the third quarter of 1998. This increase
resulted from the acquisition of new  facilities resulting in the expansion of
regional and corporate support, and additional travel, consulting and systems
development expenses associated with the Company's growth.  The Company
reimburses an affiliate for rent and other expenses related to its corporate
headquarters as well as for certain data processing and administrative services
provided to the Company. During the third quarter of 1997, such reimbursements
totaled $177,000 compared to $313,000 during the third quarter of 1998.

Depreciation and Amortization. Depreciation and amortization increased from
$989,000 in the third quarter of 1997 to $2,021,000 in the third quarter of
1998. Depreciation increased primarily as the result of the addition of
buildings and building improvements acquired in connection with the merger and
the completion of the related refinancings through the exercise of purchase
options on facilities which had previously been financed through synthetic
leases. Amortization increased primarily as the result of increased deferred
financing costs incurred in connection with the merger and the related
refinancings.

Facility Rent. Facility rent expense for the third quarter increased by
$2,434,000 from $3,031,000 in 1997 to $5,465,000  in 1998. The increase in rent
expense is the result of the acquisition of  new facilities in 1997 and 1998.

Merger costs. In connection with the merger completed on August 11, 1998, the
Company incurred merger costs of $37,172,000. Merger costs consisted of
transaction fees and expenses associated with the merger and the related
refinancings and the elimination of deferred financing costs related to debt
retired in connection with these events.

Interest Expense, net.  Interest expense, net, increased from $1,614,000 in the
third quarter of 1997 to $3,591,000 in the third quarter of 1998. This net
increase is primarily due to additional interest expense resulting from the
issuance of the Senior Subordinated Discount Notes in connection with the
Merger.

Income Taxes (Benefit). As a result of the loss incurred in the third quarter of
1998, an income tax benefit of $7,460,000 was recognized in the third quarter of
1998 as compared to income tax expense of $1,081,000 in the third quarter of
1997.

Net Income (Loss). Net income was $1,692,000 in the third quarter of 1997 as
compared to a loss of $28,900,000 in the third quarter of 1998. The net loss
reported in the third quarter of 1998 resulted from merger costs of $37,172,000
recognized in that quarter.

Nine Months Ended September 30, 1997 Compared to Nine Months Ended 
September 30, 1998

Total Net Revenues. Total net revenues increased by $71,697,000 or 46.1%, from
$155,640,000 for the first nine months of 1997 to $227,337,000 for the first
nine months of 1998. This increase resulted primarily from the acquisition of
the Harford Gardens facility on March 1, 1997, four Massachusetts facilities on
August 1, 1997, three Dayton, Ohio facilities on September 1, 1997,  five
Connecticut facilities on December 1, 1997,  two North Toledo, Ohio facilities
on April 1, 1998 and two Rhode Island facilities on May 8, 1998. Of such
increase,  $1,337,000 or 1.9% of the increase resulted from the operation of the
Harford Gardens facility, $11,803,000 or 16.5% of the increase resulted from the
operation of the Massachusetts facilities, $11,707,000 or 16.3% of the increase
resulted from the operation of the Dayton, Ohio facilities, $34,920,000 or 48.7%
of the increase resulted from the operation of the Connecticut facilities,
$5,610,000 or 7.8% of the increase resulted from the operation of the North
Toledo facilities and $4,566,000 or 6.4% of the increase resulted from the
operation of the Rhode Island facilities.  Revenues generated by providing
rehabilitation therapy services at non-affiliated long-term care facilities
decreased by $321,000 or 2.6% from $12,465,000 in the nine months of 1997 to
$12,144,000 in the nine months of 1998. The remaining $2,075,000 or 2.9% of such
increase, is largely attributable to higher average net patient service revenues
per patient day at the Company's "same store" facilities and primarily due to
increased levels of care provided to patients with medically complex conditions.
Average net patient service revenues per patient day at "same store" facilities
increased from $148.51 for the first nine months of 1997 to $151.62 for the
first nine months of 1998. Occupancy rate at "same store" facilities increased
from 91.7% for the nine months of 1997 to 92.4% for the nine months of 1998.
The average occupancy rate at all of the Company's facilities increased from
91.9% for the first nine months of 1997 to 92.6% for the first nine months of
1998.  The Company's quality mix of private, Medicare and insurance revenues was
61.2% for the first nine months ended September 30, 1997 as compared to 57.5% in
the same period of 1998.

Facility Operating Expenses. Facility operating expenses increased by
$55,844,000, or 45.0%, from $124,073,000 for the first nine months of 1997 to
$179,917,000 for the first nine months of 1998. The operation of the Harford
facility accounted for $1,604,000 or 2.9% of this increase, Massachusetts
facilities accounted for $9,981,000 or 17.9% of this increase, the operation of
the Dayton, Ohio facilities accounted for $8,784,000 or 15.7%. of this increase,
the operation of  the Connecticut facilities accounted for $27,823,000 or 49.8%
of this increase, the operation of the North Toledo facilities accounted for
$4,323,000 or 7.7% of this increase, and the operation of the Rhode Island
facilities accounted for $3,853,000 or 6.9% of this increase. Operating expenses
associated with additional non-affiliate therapy contracts decreased $1,133,000,
or 11.2%. The remainder of the increase in facility operating expenses, $609,000
or 1.1%, is primarily due to increases in the costs of labor, medical supplies
and rehabilitation therapy services purchased from third parties at "same store"
facilities.

General and Administrative; Service Charges Paid to Affiliate. General and
administrative expenses increased by $3,621,000, or 48.4%, from $7,479,000 for
the first nine months of 1997 to $11,100,000 for the first nine months of 1998.
This increase resulted from the acquisition of new facilities resulting in the
expansion of regional and corporate support, and additional travel, consulting
and systems development expenses associated with the Company's growth.  The
Company reimburses an affiliate for rent and other expenses related to its
corporate headquarters as well as for certain data processing and administrative
services provided to the Company. During the first nine months of 1997, such
reimbursements totaled $531,000 compared to $941,000 in 1998.

Depreciation and Amortization. Depreciation and amortization increased from
$2,871,000 for the first nine months of 1997 to $4,284,000 for the first nine
months of 1998. Depreciation increased primarily as the result of the addition
of buildings and building improvements acquired in connection with the merger
and the completion of the related refinancings through the exercise of purchase
options on facilities which had previously been financed through synthetic
leases. Amortization increased primarily as the result of increased deferred
financing costs incurred in connection with the merger and the related
refinancings.

Facility Rent. Facility rent expense for the first nine months increased by
$8,746,000 from $8,340,000 in 1997 to $17,086,000  in 1998. The increase in rent
expense is due to the acquisition of new facilities.

Merger costs. In connection with the merger completed on August 11, 1998, the
Company incurred merger costs of $37,172,000. Merger costs consisted of
transaction fees and expenses associated with the merger and the related
refinancings and the elimination of deferred financing costs related to debt
retired in connection with these events.

Interest Expense, net.  Interest expense, net, increased from $4,370,000 for the
first nine months of 1997 to $6,793,000 for the first nine months of 1998. This
net increase is primarily due to additional interest expense resulting from the
issuance of the Senior Subordinated Discount Notes in connection with the
Merger.

Income Taxes (Benefit). As a result of the loss incurred in the third quarter of
1998, an income tax benefit of $4,984,000 was recognized for the first nine
months of 1998 as compared to income tax expense of $3,060,000 for the first
nine months of 1997.

Net Income (Loss). Net income was $4,787,000 for the first nine months of 1997
as compared to a loss of $25,027,000 for the first nine months of 1998. The net
loss reported in 1998 resulted from merger costs of $37,172,000 recognized in
the third quarter.

LIQUIDITY AND CAPITAL RESOURCES

Harborside's primary cash needs are for acquisitions, capital expenditures,
working capital, debt service and general corporate purposes.  Harborside has
historically financed these requirements primarily through a combination of
internally generated cash flow, mortgage financing and operating leases, in
addition to funds borrowed under a previously existing credit facility.
Harborside's leased facilities are currently leased from either the owner of the
facilities or from a real estate investment trust which has purchased the
facilities from the owner, though prior to the merger, some facilities had been
leased through a trust established in conjunction with Harborside's previously
existing synthetic lease facility that was entered into in September 1997.  In
addition, in 1996, Harborside financed the acquisition of the 1996 Ohio
facilities from the owner by means of a lease which is accounted for as a
capital lease for financial reporting purposes.  Harborside's existing facility
leases generally require it to make monthly lease payments, establish escrow
funds to serve as debt service reserve accounts, and pay all property operating
costs.  Harborside generally negotiates leases which provide for extensions
beyond the initial lease term and an option to purchase the leased facility.  In
some cases, the option to purchase the leased facility is exercisable at a price
based on the fair market value of the facility at the time the option is
exercised.  In other cases, the lease for the facility sets forth a fixed option
purchase price which Harborside believes is equal to the fair market value of
the facility at the inception date of such lease, thus allowing Harborside to
realize the value appreciation, if any, of the facility while maintaining
financial flexibility.

The Company's operating activities during the first nine months of 1998 required
the use of net cash of $28.9 million as compared to the generation of net cash
of $4.0 million during the same period in 1997. The decrease in net cash
generated by operations during the first nine months of 1998 was the result of
the recognition of $37.2 million of transaction costs associated with the merger
that was completed on August 11, 1998. Partially offsetting these non-recurring
costs were non-cash addbacks totaling $8.5 million and including depreciation
and amortization, and the addback of non-cash components of interest expense.
Accounts receivable increased by $12.3 million during the first nine months of
1998, primarily as the result of the acquisition of new facilities. The effect
of this increase was mostly offset by related increases in the accruals for
employee compensation and other liabilities totaling $9.6 million. Prepaid
income taxes increased by $7.7 million as a result of the recognition of a tax
benefit that resulted from the loss caused by the non-recurring merger costs.

Net cash used by investing activities was $84.2 million during the first nine
months of 1998 as compared to $5.9 million used during the same period in 1997.
The primary use of cash for investing purposes during 1998 was the addition of
$65.9 million of property, plant and equipment primarily related to the exercise
of purchase options on facilities previously leased through the Company's prior
synthetic leasing facility. Additions to property, plant and equipment totaled
$2.1 million in the prior year period. Additions to intangible assets during the
first nine months of 1998 were $18.8 million. Most of these additions related to
deferred financing costs incurred in connection with the issuance of the
Company's Senior Subordinated Discount Notes and Preferred Stock and the
establishment of a $250 million credit facility. Additions to intangible assets
totaled $4.7 million in the prior year period, most of which also related to the
costs of various financings.

Net cash provided by financing activities during the first nine months of 1998
was $110.2 million as compared to $4.0 million during the first nine months of
1997. During the first nine months of 1998 the Company borrowed $4.4 million
under its previously existing credit facility. The Company repaid the borrowings
under that credit facility at the date of the merger, at which time it also
borrowed $12.8 million under its new credit facility. In connection with the
merger, the Company received gross proceeds of $99.5 million through the
issuance of its Senior Subordinated Discount Notes. The Company also received
gross proceeds of $40.0 million through the issuance of its Preferred Stock in
connection with the merger. In connection with these transactions and prior to
the merger, the New Investors made common equity cash contributions totaling
$165.0 million ($158.5 million, net of issuance costs). The merger required the
use of $183.7 million of cash to redeem previously outstanding shares of the
Company's common stock.

At September 30, 1998, the Company had two mortgage loans outstanding in the
aggregate amount of $17.9 million, in addition to advances outstanding under its
new credit facility, and $55.7 million of capital lease obligations.  One of the
Company's mortgage loans had an outstanding balance of $16.3 million, of which
$15.1 million is due at maturity in 2004. This loans bears interest at an annual
rate of 10.65% plus additional interest equal to 0.3% of the difference between
the annual operating revenues of four mortgaged facilities and the actual
revenues of these facilities during a twelve month base period. The Company's
other mortgage loan, which encumbers a single facility, had an outstanding
principal balance of $1.6 million, of which $1.3 million is due in 2010.


                                      -19-

The Company expects that its capital expenditures for 1998, excluding
acquisitions of new long-term care facilities, will aggregate approximately
$10.0 million, $7.0 million of which had already been invested through September
30, 1998. The Company's expected capital expenditures will relate to, among
other things, maintenance capital expenditures, systems enhancements, special
construction projects and other capital improvements.  The Company expects that
the majority of its facility acquisitions will be financed with borrowings under
its credit facility.  However, the Company may be required to assume debt or to
obtain other debt and/or equity financing to finance any significant
acquisitions or real estate/construction projects in the future.

The Company's principal sources of funds are cash flow from operations and
borrowings under its credit facility.  These funds are being used to finance
working capital, meet debt service and capital expenditure requirements, and for
general corporate purposes.  It is anticipated that these funds will also be
used to finance acquisitions and lease real estate.  The Company believes that
operating cash flow and availability under its credit facility will be adequate
to meet its liquidity needs for the foreseeable future, although no assurance
can be given in this regard.

YEAR 2000 DISCLOSURE

Harborside is preparing all of its software products and internal computer
systems to be Year 2000 compliant. Harborside has replaced its financial 
reporting and payroll systems with systems that are Year 2000 compliant. 
Harborside is in the process of evaluating several clinical information software
products, including one which has been installed in 13 of its facilities, with 
the expectation that it will identify a Year 2000 compliant standard clinical 
information and patient billing system which will be implemented at each of 
Harborside's facilities. Harborside currently estimates that it will complete 
the selection of the standard clinical information and patient billing software
during 1998 and finalize the conversion of its existing systems to the new
platform during 1999. Although Harborside does not expect the cost of the
conversion of its clinical and patient billing systems to have a material
adverse effect on its business or future results of operations, there can be no
assurance that Harborside will not be required to incur significant
unanticipated costs in relation to its compliance obligations.

Harborside currently estimates that compliance will be achieved during 1999;
however, there can be no assurance that Harborside will be able to complete the
conversion in a timely manner or that third party software suppliers will be
able to provide Year 2000 compliant products for Harborside to install.
Harborside currently estimates the cost of preparing its systems to be Year
2000 compliant to be approximately $1.0 million. Harborside will fund the costs
associated with these system conversions through cash flows from operations or
borrowings under its Credit Facility. Harborside's ongoing facility acquisition
strategy will require it to evaluate acquisition candidates for Year 2000
compliance.

SEASONALITY

The Company's earnings generally fluctuate from quarter to quarter.  This
seasonality is related to a combination of factors which include the timing and
amount of Medicaid rate increases, seasonal census cycles, and the number of
days in a given fiscal quarter.

INFLATION

The healthcare industry is labor intensive. Wages and other labor related costs
are especially sensitive to inflation. Certain of the Company's other expense
items, such as supplies and real estate costs are also sensitive to inflationary
pressures. Shortages in the labor market or general inflationary pressure could
have a significant effect on the Company. In addition, suppliers pass along
rising costs to the Company in the form of higher prices. When faced with
increases in operating costs, the Company has sought to increase its charges for
services and its requests for reimbursement from government programs. The
Company's private pay customers and third party reimbursement sources may be
less able to absorb increased prices for the Company's services. The Company's
operations could be adversely affected if it is unable to recover future cost
increases or experiences significant delays in increasing rates of reimbursement
of its labor or other costs from Medicare and Medicaid revenue sources.

caption "Management's Discussion and Analysis of Financial Condition and Results
of Operations", constitute "Forward-Looking Statements" within the meaning of
the Private Securities Litigation Reform Act of 1995 (the "Reform Act").  The

     long-term care facilities or the acquisition of ancillary businesses.

2.   The Company's ability to identify suitable acquisition candidates, to
     consummate or complete construction projects, or to profitably operate or
     successfully integrate enterprises into the Company's other operations.

3.   The occurrence of changes in the mix of payment sources utilized by the
     Company's patients to pay for the Company's services.

4.   The adoption of cost containment measures by private pay sources such as
     commercial insurers and managed care organizations, as well as efforts by
     governmental reimbursement sources to impose cost containment measures.

5.   Changes in the United States healthcare system, including changes in
     reimbursement levels under Medicaid and Medicare, and other changes in
     applicable government regulations that might affect the profitability of
     the Company.

6.   The Company's continued ability to operate in a heavily regulated
     environment and to satisfy regulatory authorities, thereby avoiding a
     number of potentially adverse consequences, such as the imposition of
     fines, temporary suspension of admission of patients, restrictions on the
     ability to acquire new facilities, suspension or de-certification from
     Medicaid or Medicare programs, and in extreme cases, revocation of a
     facility's license or the closure of a facility, including as a result of
     unauthorized activities by employees.

7.   The Company's ability to secure the capital and the related cost of such
     capital necessary to fund its future growth through acquisition and
     development, as well as internal growth.

8.   Changes in certificate of need laws that might increase competition in the
     Company's industry, including, particularly, in the states in which the
     Company currently operates or anticipates operating in the future.

9.   The Company's ability to staff its facilities appropriately with qualified
     healthcare personnel, including in times of shortages of such personnel and
     to maintain a satisfactory relationship with labor unions.

10.  The level of competition in the Company's industry, including without
     limitation, increased competition from acute care hospitals, providers of
     assisted and independent living and providers of home healthcare and
     changes in the regulatory system in the state in which the Company operates
     that facilitate such competition.

11.  The continued availability of insurance for the inherent risks of liability
     in the healthcare industry.

12.  Price increases in pharmaceuticals, durable medical equipment and other
     items.

13.  The Company's reputation for delivering high-quality care and its ability
     to attract and retain patients, including patients with  relatively high
     acuity levels.

14.  Changes in general economic conditions, including changes that pressure
     governmental reimbursement sources to reduce the amount and scope of
     healthcare coverage.

The foregoing review of significant factors should not be construed as
exhaustive or as an admission regarding the adequacy of disclosures previously
made by the Company.
