                 11% Senior Subordinated Discount Note due 2008

1.   Interest
     --------

          HARBORSIDE HEALTHCARE CORPORATION, a Delaware corporation (the
"Company"), promises to pay interest on the principal amount of this Security at
the rate per annum shown above and shall pay Liquidated Damages, if any, payable
pursuant to the relevant Registration Rights Agreement.

          The Company will pay interest and Liquidated Damages, if any,
semiannually on August 1 and February 1 of each year commencing February 1,
2004; provided that no interest shall accrue on the principal amount of this
      --------                                                              
Security prior to August 1, 2003 (the "Full Accretion Date"), and no interest
shall be paid on this Security prior to the Full Accretion Date except for
Liquidated Damages, if any, payable pursuant to the relevant Registration Rights
Agreement.  The Holder of this Security is entitled to the benefit of such
Registration Rights Agreement.

          Interest will be computed on the basis of a 360-day year of twelve 30-
day months. The Company shall pay interest on overdue principal at the rate
borne by the Securities, and it shall pay interest on overdue installments of
interest at the same rate to the extent lawful.


2.   Method of Payment
     -----------------

          The Company will pay interest (except defaulted interest) on and
Liquidated Damages, if any, in respect of the Securities to the Persons who are
registered holders of Securities at the close of business on the January 15 or
July 15 next preceding the interest payment date even if Securities are
cancelled after the record date and on or before the interest payment date.
Holders must surrender Securities to a Paying Agent to collect principal
payments.  The Company will pay principal and interest in money of the United
States that at the time of payment is legal tender for payment of public and
private debts.  However, the Company may pay principal and interest by check
payable in such money or by wire transfer of federal funds.


3.   Paying Agent and Registrar
     --------------------------

          Initially, UNITED STATES TRUST COMPANY OF NEW YORK (the  "Trustee")
will act as Paying Agent and Registrar.  The Company may appoint and change any
Paying Agent, Registrar or co-registrar without notice to the Holders.  The
Company or any domestically organized Wholly Owned Restricted Subsidiary may act
as Paying Agent, Registrar or co-registrar.

 
                                      A-6

4.   Indenture
     ---------

          The Company issued the Securities under an Indenture dated as of July
31, 1998 (the "Indenture"), between the Company and the Trustee.  The terms of
the Securities include those stated in the Indenture and those made part of the
Indenture by reference to the Trust Indenture Act of 1939 (15 U.S.C. (S)(S)
                                                              ------       
77aaa-77bbbb) as in effect on the date of the Indenture (the "Act").  Terms
defined in the Indenture and not defined herein have the meanings ascribed
thereto in the Indenture.  The Securities are subject to all such terms, and
Securityholders are referred to the Indenture and the Act for a statement of
those terms.

          The Securities are unsecured senior subordinated obligations of the
Company. Subject to the conditions set forth in the Indenture, the Company may
issue Additional Securities.

5.   Optional Redemption
     -------------------

          Except as set forth in the next two paragraphs, the Securities may not
be redeemed at the Company's option prior to August 1, 2003.  Thereafter, the
Securities will be subject to redemption at any time at the option of the
Company, in whole or in part, upon not less than 30 nor more than 60 days'
notice at the redemption prices (expressed as percentages of principal amount)
set forth below plus accrued and unpaid interest and Liquidated Damages thereon,
if any, to the applicable redemption date (subject to the right of Holders on
the relevant record date to receive interest due on the relevant interest
payment date), if redeemed during the twelve-month period beginning on August 1

                       Redemption
Year                    Price

2003                    103.667%
2004                    101.883%
2005                    100.000%
2006 and thereafter

          In addition, at any time and from time to time, prior to August 1,
2001, the Company may redeem up to 35% of the sum of (i) the aggregate principal
amount at maturity of Securities and (ii) the aggregate principal amount at
maturity of any Additional Securities at a redemption price of 111% of the
Accreted Value thereof (determined at the redemption date) plus Liquidated
Damages thereon, if any, to the redemption date, with the net cash proceeds
received by the Company of a public offering of common stock of the Company,
provided that at least 65% of the sum of (i) the aggregate principal amount at
- --------                                                                      
maturity of Securities and (ii) the aggregate principal amount at maturity of
any Additional Securities remains outstanding immediately after the occurrence
of such redemption; and provided, further, that such redemption shall occur
                        --------  -------                                  
within 60 days of the date of the closing of such public offering.

 
                                      A-7

          At any time on or prior to August 1, 2003, the Securities may be
redeemed as a whole but not in part at the option of the Company upon the
occurrence of a Change of Control, upon not less than 30 nor more than 60 days'
prior notice (but in no event may any such redemption occur more than 90 days
after the occurrence of such Change of Control) mailed by first-class mail to
each Holder's registered address, at a redemption price equal to 100% of the
Accreted Value thereof (determined at the redemption date) plus the Applicable
Premium and Liquidated Damages thereon, if any, to the redemption date (subject
to the right of Holders on the relevant record date to receive interest due on
the relevant interest payment date).

6.   Special Mandatory Redemption
     ----------------------------

          In the event that the Merger is not consummated prior to the earlier
to occur of (i) January 10, 1999 and (ii) if it appears, in the sole judgment of
the Company, that the Merger shall not be consummated, the date on which notice
of same is delivered by the Company to the Escrow Agent and the Trustee, the
Company shall be required to redeem the Securities, in whole, on at least 15
days' prior written notice mailed by first class mail to each Holder's last
address as it appears in the Securities Register, at a redemption price equal to
101% of the Accreted Value plus Liquidated Damages, if any, of the Securities on
the date of repurchase to the redemption date.

7.   Notice of Redemption
     --------------------

          Notice of redemption will be mailed by first-class mail at least 30
days (or in the case of a Special Mandatory Redemption described in paragraph 6
hereof, 15 days) but not more than 60 days before the redemption date to each
Holder of Securities to be redeemed at its registered address all in accordance
with the Indenture.  If less than all of the Securities are to be redeemed at
any time, selection of Securities for redemption will be made by the Trustee in
compliance with the requirements of the principal national securities exchange,
if any, on which the Securities are listed, or, if the Securities are not so
listed, on a pro rata basis, by lot or by such method as the Trustee shall deem
fair and appropriate; provided that no Securities in an aggregate principal
                      --------                                             
amount at maturity of $1,000 or less shall be redeemed in part.

          If money sufficient to pay the redemption price of and accrued
interest (if any) on all Securities (or portions thereof) to be redeemed on the
redemption date is deposited with the Paying Agent on or before the redemption
date and certain other conditions are satisfied, on and after such date interest
ceases to accrue on such Securities (or such portions thereof) called for
redemption.


8.   Repurchase at the Option of the Holder
     --------------------------------------

          Upon a Change of Control, any Holder of Securities will have the
right, subject to certain conditions set forth in the Indenture, to cause the
Company to repurchase all or any part of 

 
                                      A-8

the Securities of such Holder at a purchase price equal to 101% of the aggregate
principal amount of the Securities to be repurchased plus accrued and unpaid
interest and Liquidated Damages thereon, if any, to the date of repurchase
(subject to the right of Holders of record on the relevant record date to
receive interest due on the relevant interest payment date that is on or prior
to the date of repurchase) as provided in, and subject to the terms of, the
Indenture.


9.   Subordination
     -------------

          The Securities are subordinated to Senior Debt of the Company, as
defined in the Indenture.  To the extent provided in the Indenture, Senior Debt
of the Company must be paid before the Securities may be paid. The Company
agrees, and each Securityholder by accepting a Security agrees, to the
subordination provisions contained in the Indenture and authorizes the Trustee
to give it effect and appoints the Trustee as attorney-in-fact for such purpose.


10.  Denominations; Transfer; Exchange
     ---------------------------------

          The Securities are in registered form without coupons in denominations
of $1,000 and whole multiples of $1,000.  A Holder may transfer or exchange
Securities in accordance with the Indenture.  Upon any registration of transfer
or exchange, the Registrar and the Trustee may require a Holder, among other
things, to furnish appropriate endorsements or transfer documents and to pay any
taxes required by law or permitted by the Indenture.  The Registrar need not
register the transfer of or exchange any Securities selected for redemption
(except, in the case of a Security to be redeemed in part, the portion of the
Security not to be redeemed) or to transfer or exchange any Securities for a
period of 15 days prior to a selection of Securities to be redeemed or 15 days
before an interest payment date.


11.  Persons Deemed Owners
     ---------------------

          The registered Holder of this Security may be treated as the owner of
it for all purposes.


12.  Unclaimed Money
     ---------------

          If money for the payment of principal or interest remains unclaimed
for two years, the Trustee or Paying Agent shall pay the money back to the
Company at its written request unless an abandoned property law designates
another Person.  After any such payment, Holders entitled to the money must look
only to the Company and not to the Trustee for payment.

 
                                      A-9

13.  Discharge and Defeasance
     ------------------------

          Subject to certain conditions set forth in the Indenture, the Company
at any time may terminate some or all of its obligations under the Securities
and the Indenture if the Company deposits with the Trustee money or Government
Obligations for the payment of principal and interest on the Securities to
redemption or maturity, as the case may be.


14.  Amendment, Waiver
     -----------------

          Subject to certain exceptions set forth in the Indenture, (i) the
Indenture or the Securities may be amended with the written consent of the
Holders of at least a majority in principal amount outstanding of the Securities
and (ii) any past default or noncompliance with any provision of the Indenture
may be waived with the consent of the Holders of a majority in principal amount
then outstanding of the Securities.  Subject to certain exceptions set forth in
the Indenture, without the consent of any Securityholder, the Company and the
Trustee may amend the Indenture or the Securities to cure any ambiguity, defect
or inconsistency, to provide for uncertificated Securities in addition to or in
place of certificated Securities (provided that the uncertificated Securities
are issued in registered form for purposes of Section 163(f) of the Code, or in
a manner such that the uncertificated Securities are described in Section
163(f)(2)(B) of the Code), to provide for the assumption of the Company's or any
Guarantor's obligations to Holders of Securities in the case of a merger,
consolidation or sale of assets, to release any Security Guarantee or collateral
in accordance with the provisions of the Indenture or Pledge Agreement, as the
case may be, to provide for additional Guarantors, to make any change that would
provide any additional rights or benefits to the Holders of Securities or that,
as determined by the Board of Directors in good faith, does not have a material
adverse effect on the legal rights under this Indenture of any such Holder, to
comply with requirements of the SEC in order to effect or maintain the
qualification of the Indenture under the TIA or to provide for the issuance of
Additional Securities in compliance with Article II and Section 4.03 of the
Indenture.


15.  Defaults and Remedies
     ---------------------

          Under the Indenture, an Event of Default occurs if:  (i) the Company
defaults in any payment of interest on, or Liquidated Damages with respect to,
any Security when the same becomes due and payable, whether or not such payment
shall be prohibited by Article X of the Indenture, and such default continues
for a period of 30 days; (ii) the Company defaults in the payment of the
principal of or premium, if any, on the Securities, whether or not such payment
shall be prohibited by Article X of the Indenture; (iii) the Company fails to
comply with other covenants and agreements in the Indenture, subject to
applicable grace periods as set forth in the Indenture; (iv) certain
accelerations (including failure to pay within any grace period after final
maturity) of other Debt of the Company or any Restricted Subsidiary that is a
Significant Subsidiary occur if the amount 

 
                                     A-10

accelerated (or so unpaid) exceeds $15,000,000; (v) certain events of
bankruptcy, insolvency or reorganization with respect to the Company and any
Restricted Subsidiary which is a Significant Subsidiary; (vi) certain judgments
or decrees for the payment of money in excess of $15,000,000 against the Company
or any Restricted Subsidiary that is a Significant Subsidiary; and (vii) except
as is permitted by the Indenture, a Security Guarantee by a Guarantor that is a
Significant Subsidiary shall be held in any judicial proceeding to be
unenforceable or invalid or shall for any reason cease to be in full force and
effect or any Guarantor, or any Person acting on behalf of any Guarantor, denies
or disaffirms its obligations under the Indenture or its Security Guarantee. If
an Event of Default occurs and is continuing, the Trustee or the Holders of at
least 25% in principal amount of the Securities may declare all the Securities
to be due and payable.

          Securityholders may not enforce the Indenture or the Securities except
as provided in the Indenture.  The Trustee may refuse to enforce the Indenture
or the Securities unless it receives reasonable indemnity or security.  Subject
to certain limitations, Holders of a majority in principal amount of the
Securities may direct the Trustee in its exercise of any trust or power.  The
Trustee may withhold from Securityholders notice of any continuing Default
(except a Default in payment of principal, premium, if any, or interest) if and
so long as a committee of its trust officers in good faith determines that
withholding notice is in the interest of the Holders.


16.  Trustee Dealings with the Company
     ---------------------------------

          Subject to certain limitations imposed by the Act,  the Trustee under
the Indenture, in its individual or any other capacity, may become the owner or
pledgee of Securities and may otherwise deal with and collect obligations owed
to it by the Company or its Affiliates and may otherwise deal with the Company
or its Affiliates with the same rights it would have if it were not Trustee.


17.  No Personal Liability of Directors, Officers, Employees and Stockholders
     ------------------------------------------------------------------------

          No director, officer, employee, incorporator, stockholder or Affiliate
of the Company, as such, will have any liability for any obligations of the
Company under the Securities, the Indenture or for any claim based on, in
respect of, or by reason of, such obligations or their creation.  No director,
officer, employee, incorporator, stockholder or Affiliate of any of the
Guarantors, as such, will have any liability for any obligations of the
Guarantors under the Security Guarantees, the Indenture or for any claim based
on, in respect of, or by reason of, such obligations or their creation. Each
Holder of Securities and Security Guarantees by accepting a Security and a
Security Guarantee waives and releases all such liabilities.  The waiver and
release are part of the consideration for issuance of the Securities and the
Security Guarantees.  Such waiver may not be effective to waive liabilities
under the federal securities laws and it is the view of the SEC that such a
waiver is against public policy.

 
                                     A-11

18.  Governing Law
     -------------

          THE SECURITIES SHALL BE GOVERNED BY, AND CONSTRUED IN ACCORDANCE WITH,
          ----------------------------------------------------------------------
THE LAWS OF THE STATE OF NEW YORK WITHOUT GIVING EFFECT TO APPLICABLE PRINCIPLES
- --------------------------------------------------------------------------------
OF CONFLICTS OF LAW TO THE EXTENT THAT THE APPLICATION OF THE LAWS OF ANOTHER
- -----------------------------------------------------------------------------
JURISDICTION WOULD BE REQUIRED THEREBY.
- ---------------------------------------


19.  Authentication
     --------------

          This Security shall not be valid until an authorized signatory of the
Trustee (or an authenticating agent) manually signs the certificate of
authentication on the other side of this Security.


20.    Abbreviations
       -------------

          Customary abbreviations may be used in the name of a Securityholder or
an assignee, such as TEN COM (=tenants in common), TEN ENT (=tenants by the
entireties), JT TEN (=joint tenants with rights of survivorship and not as
tenants in common), CUST (=custodian), and U/G/M/A (=Uniform Gift to Minors
Act).


21.  CUSIP Numbers
     -------------

          Pursuant to a recommendation promulgated by the Committee on Uniform
Security Identification Procedures the Company has caused CUSIP numbers to be
printed on the Securities and have directed the Trustee to use CUSIP numbers in
notices of redemption as a convenience to Securityholders.  No representation is
made as to the accuracy of such numbers either as printed on the Securities or
as contained in any notice of redemption and reliance may be placed only on the
other identification numbers placed thereon.

22.  Guarantee
     ---------

          The Company's obligations under the Securities are guaranteed on a
senior subordinated basis, jointly and severally, by the Guarantors.

Dear Sirs:

          In connection with our proposed purchase of $__________________
aggregate principal amount at maturity of the Securities, we confirm that:

          1.   We understand that any subsequent transfer of the Securities is
subject to certain restrictions and conditions set forth in the Indenture dated
as of July 31, 1998 (the "Indenture") relating to the Securities and the
undersigned agrees to be bound by, and not to resell, pledge or otherwise
transfer the Securities except in compliance with such restrictions and
conditions and the Securities Act of 1933, amended (the "Securities Act").

          2.   We understand that the offer and sale of the Securities have not
been registered under the Securities Act, and that the Securities may not be
offered or sold except as permitted in the following sentence. We agree, on our
own behalf and on behalf of any accounts for which we are acting as hereinafter
stated, that if we should sell any Securities within the time period referred to
in Rule 144(k) of the Securities Act, we will do so only (A) to the Company or
any subsidiary thereof, (B) in accordance with Rule 144A under the Securities
Act to a "qualified institutional buyer" (as defined therein), (C) to an
institutional "accredited investor" (as defined below) that, prior to such
transfer, furnishes (or has furnished on its behalf by a U.S. broker-dealer) to
you and to the Company a signed letter substantially in the form of this letter
and, if such transfer is in respect of an aggregate accreted value of Securities
at the time of transfer of less than $250,000, an opinion of counsel acceptable
to the Company that such transfer is in compliance with the Securities Act, (D)
outside the United States in accordance with Rule 904 of Regulation S under the
Securities Act, (E) pursuant to the exemption from registration provided by Rule
144 under the Securities Act (if available) or (F) pursuant to an effective
registration statement under the Securities Act, and we further agree to provide
to any person purchasing any of the Securities from us a notice advising such
purchaser that resales of the Securities are restricted as stated herein.

 
                                      C-2

          3.   We understand that, on any proposed resale of any Securities, we
will be required to furnish to you and the Company such certifications, legal
opinions and other information as you and the Company may reasonably require to
confirm that the proposed sale complies with the foregoing restrictions. We
further understand that the Securities purchased by us will bear a legend to the
foregoing effect.

          4.   We are an institutional "accredited investor" (as defined in Rule
501(a)(1), (2), (3) or (7) of Regulation D under the Securities Act) and have
such knowledge and experience in financial and business matters as to be capable
of evaluating the merits and risks of our investment in the Securities, and we
and any accounts for which we are acting are each able to bear the economic risk
of our or its investment.

          5.   We are acquiring the Securities purchased by us for our own
account or for one or more accounts (each of which is an institutional
"accredited investor") as to each of which we exercise sole investment
discretion.

          You and the Company are entitled to rely upon this letter and are
irrevocably authorized to produce this letter or a copy hereof to any interested
party in any administrative or legal proceedings or official inquiry with
respect to the matters covered hereby.
