                              (REVERSE OF SECURITY)

                    8-1/4% SENIOR SUBORDINATED NOTE DUE 2013

                  1.       Interest. Mariner Health Care, Inc., a Delaware
corporation (the "Company"), promises to pay interest on the principal amount of
this Note at the rate per annum shown above. Interest on the Notes will accrue
from the most recent date to which interest has been paid or, if no interest has
been paid, from December 19, 2003. The Company will pay interest semi-annually
in arrears on each Interest Payment Date, commencing June 15, 2004. 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 and on
overdue installments of interest (without regard to any applicable grace
periods) to the extent lawful from time to time on demand at the rate borne by
the Notes.

                  2.       Method of Payment. The Company shall pay interest on
the Notes (except defaulted interest) to the Persons who are the registered
Holders at the close of business on June 1 or December 1 immediately preceding
the Interest Payment Date (whether or not such day is a Business Day) even if
the Notes are cancelled on registration of transfer or registration of exchange
after such Record Date. Holders must surrender Notes to a Paying Agent to
collect principal payments. Payments of principal and premium, if any, will be
made (on presentation of such Notes if in certificated form) in money of the
United States that at the time of payment is legal tender for payment of public
and private debts; provided, however, that the Company may pay principal,
premium, if any, and interest by check payable in such money. The Company may
deliver any such interest payment to the Paying Agent or to a Holder at the
Holder's registered address.

                  3.       Paying Agent and Registrar. Initially, U.S. Bank
National Association (the "Trustee"), will act as Paying Agent and Registrar.
The Company may change any Paying Agent, Registrar or co-Registrar without
notice to the Holders. The Company or any of its Subsidiaries may act as Paying
Agent or Registrar.

                  4.       Indenture. The Company issued this Note under an
Indenture, dated as of December 19, 2003 (the "Indenture"), by and among the
Company, the Guarantors and the Trustee. This Note is one of a duly authorized
issue of Initial Notes of the Company designated as its 8-1/4% Senior
Subordinated Notes due 2013 (the "Notes"). The Notes include the Initial Notes,
the Additional Notes and the Exchange Notes (as defined below) issued in
exchange for the Initial Notes and Additional Notes pursuant to the Indenture.
The Initial Notes, the Additional Notes and the Exchange Notes are treated as a
single class of securities under the Indenture. Capitalized terms herein are
used as defined in the Indenture unless otherwise defined herein. The terms of
the Notes 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. Code Sections
77aaa-77bbbb) (the "TIA"), as in effect on the date of the Indenture.
Notwithstanding anything to the contrary herein, the Notes are subject to all
such terms, and Holders are referred to the Indenture and the TIA for a
statement of them. The Notes are general unsecured obligations of the Company.

                  5.       Subordination. The Notes are unsecured obligations of
the Company and subordinated in right of payment, in the manner and to the
extent set forth in the Indenture, to the prior payment in full in cash of all
Senior Indebtedness of the Company, whether outstanding on the date of the
Indenture or thereafter created, incurred, assumed or guaranteed. Each Holder by
his acceptance hereof agrees to be bound by such provisions and authorizes and
expressly directs the Trustee, on his behalf, to take such action as may be
necessary or appropriate to effectuate the subordination provided for in the
Indenture and appoints the Trustee his attorney-in-fact for such purposes.

                  6.       Guarantee. The obligations of the Company hereunder
are guaranteed on a senior subordinated basis by the Guarantors. Each Guarantee
by a Guarantor is subordinated in right of payment to all Senior Indebtedness of
such Guarantor to the same extent that the Notes are subordinated to Senior
Indebtedness of the Company.

Notes, at its option, in whole at any time or in part from time to time, on and

</TABLE>

                  (b)      Optional Redemption upon Equity Offerings.
Notwithstanding the foregoing, the Company may redeem in the aggregate up to 35%
of the original principal amount of Notes at any time and from time to time
prior to December 15, 2006 at a Redemption Price equal to 108.250% of the
aggregate principal amount so redeemed, plus accrued and unpaid interest, if
any, to the Redemption Date out of the Net Proceeds of one or more Equity
Offerings; provided that

                  (1)      at least 65% of the aggregate principal amount of
         Notes originally issued remains outstanding immediately after the
         occurrence of any such redemption and

                  (2)      any such redemption occurs within 90 days following
         the closing of such Equity Offering.

                  8.       Notice of Redemption. Notice of redemption under
paragraphs 7(a) and 7(b) of this Note will be mailed at least 30 days but not
more than 60 days before the Redemption Date to each Holder to be redeemed at
such Holder's registered address.

                  Except as set forth in the Indenture, if monies for the
redemption of the Notes called for redemption shall have been deposited with the
Paying Agent for redemption on such Redemption Date, then, unless the Company
defaults in the payment of such Redemption Price plus accrued interest, if any,
the Notes called for redemption will cease to bear interest from and after such
Redemption Date and the only right of the Holders of such Notes will be to
receive payment of the Redemption Price plus accrued interest, if any.

                  9.       Offers to Purchase. The Indenture provides that,
after certain Asset Sales (as defined in the Indenture) and upon the occurrence
of a Change of Control (as defined in the Indenture), and subject to further
limitations contained therein, the Company will make an offer to purchase
certain amounts of the Notes in accordance with the procedures set forth in the
Indenture.

                  10.      Registration Rights. Pursuant to the Registration
Rights Agreement by and among the Company, the Guarantors and the Initial
Purchasers, the Company will be obligated to consummate an exchange offer
pursuant to which the Holder of this Note shall have the right to exchange this
Note for the Company's Series B 8 1/4% Senior Subordinated Notes due 2013 (the
"Exchange Notes"), which have been registered under the Securities Act, in like
principal amount and having terms identical in all material respects to the
Initial Notes. The Holders of the Initial Notes shall be entitled to receive
certain Additional Interest payments in the event such exchange offer is not
consummated and upon certain other conditions, all pursuant to and in accordance
with the terms of the Registration Rights Agreement.

                  11.      Denominations; Transfer; Exchange. The Notes are in
registered form, without coupons, in denominations of $1,000 and integral
multiples thereof. A Holder shall register the transfer or exchange of Notes in
accordance with the Indenture. The Registrar may require a Holder, among other
things, to furnish appropriate endorsements and transfer documents and to pay
certain transfer taxes or similar governmental charges payable in

                                      -5-
<PAGE>

connection therewith as permitted by the Indenture. The Registrar need not
register the transfer of or exchange of any Notes or portions thereof selected
for redemption.

                  12.      Persons Deemed Owners. The registered holder of a
Note shall be treated as the owner of it for all purposes.

                  13.      Unclaimed Money. If money for the payment of
principal or interest remains unclaimed for two years, the Trustee and the
Paying Agent will pay the money back to the Company. After that, Holders
entitled to money must look to the Company for payment as general creditors
unless an "abandoned property" law designates another person.

                  14.      Legal Defeasance and Covenant Defeasance. If the
Company at any time deposits with the Trustee U.S. legal tender or U.S.
government obligations sufficient to pay the principal of and interest on the
Notes to redemption or maturity and complies with the other provisions of the
Indenture relating to defeasance, the Company will be discharged from certain
provisions of the Indenture and the Notes (including certain covenants, but
excluding its obligation to pay the principal of and interest on the Notes).

                  15.      Amendments, Supplements, and Waivers. Subject to
certain exceptions, the Indenture or the Notes may be amended or supplemented
with the written consent of the Holders of at least a majority in aggregate
principal amount of the Notes then outstanding, and any existing Default or
Event of Default or noncompliance with any provision may be waived with the
written consent of the Holders of a majority in aggregate principal amount of
the Notes then outstanding. Without notice to or consent of any Holder, the
parties thereto may amend or supplement the Indenture or the Notes to, among
other things, cure any ambiguity, defect or inconsistency, provide for
uncertificated Notes in addition to or in place of certificated Notes or make
any other change that does not adversely affect in any material respect the
rights of any Holder.

                  16.      Restrictive Covenants. The Indenture imposes certain
limitations on the ability of the Company and its Restricted Subsidiaries to,
among other things, incur additional Indebtedness, make payments in respect of
its Capital Stock, enter into transactions with Affiliates, create dividend or
other payment restrictions affecting Restricted Subsidiaries, sell assets,
create liens, issue capital stock, enter into sale and lease-back transactions,
make certain Investments, merge or consolidate with any other Person, or sell,
assign, transfer, lease, convey or otherwise dispose of all or substantially all
of its assets. Such limitations are subject to a number of important
qualifications and exceptions. The Company must quarterly report to the Trustee
on compliance with such limitations.

                  17.      Successor Entity. When a successor entity assumes, in
accordance with the Indenture, all the obligations of its predecessor under the
Notes and the Indenture, and immediately before and thereafter no Default or
Event of Default exists and certain other conditions are satisfied, the
predecessor entity will be released from those obligations.

                  18.      Defaults and Remedies. Events of Default are set
forth in the Indenture. If an Event of Default (other than an Event of Default
pursuant to Section 6.01(f) or (g) of the Indenture) shall have occurred and be
continuing, then the Trustee or the Holders of not less than 25% in aggregate
principal amount of the Notes then outstanding, may declare to be immediately
due and payable the entire principal amount of all the Notes then outstanding
plus accrued interest to the date of acceleration; provided, however, that after
such acceleration but before a judgment or decree based on such acceleration is
obtained by the Trustee, the Holders of a majority in aggregate principal amount
of the outstanding Notes may rescind and annul such acceleration and its
consequences if all existing Events of Default, other than the nonpayment of
principal, premium, if any, or interest that has become due solely because of
the acceleration, have been cured or waived. No such rescission shall affect any
subsequent Default or impair any right consequent thereto. In case an Event of
Default specified in Section 6.01(f) or (g) of the Indenture occurs, such
principal amount, together with premium, if any, and interest with respect to
all of the Notes, shall be due and payable immediately without any declaration
or other act on the part of the Trustee or the Holders. The Trustee is not
obligated to enforce the Indenture or the Notes unless it has received indemnity
reasonably satisfactory to it.

                  19.      Trustee Dealings with Company. The Trustee under the
Indenture, in its individual or any other capacity, may make loans to, accept
deposits from, and perform services for the Company, and may otherwise deal with
the Company, its Subsidiaries or their respective Affiliates as if it were not
the Trustee.

                  20.      No Recourse Against Others. As more fully described
in the Indenture, no director, officer, employee, stockholder or incorporator,
as such, of the Company shall have any liability for any obligation of the
Company under the Notes or the Indenture or for any claim based on, in respect
of or by reason of such obligations or their creation. Each Holder by accepting
a Note waives and releases all such liability. Such waiver and release are part
of the consideration for the issuance of the Notes.

                  21.      Authentication. This Note shall not be valid until
the Trustee or Authenticating Agent manually signs the certificate of
authentication on this Note.

                  22.      Governing Law. THIS NOTE SHALL BE GOVERNED BY AND
CONSTRUED IN ACCORDANCE WITH THE LAWS OF THE STATE OF NEW YORK, AS APPLIED TO
CONTRACTS MADE AND PERFORMED WITHIN THE STATE OF NEW YORK, WITHOUT REGARD TO
PRINCIPLES OF CONFLICTS OF LAW. EACH OF THE PARTIES TO THE INDENTURE HAS AGREED

ACTION OR PROCEEDING ARISING OUT OF OR RELATING TO THIS NOTE.

                  24.      CUSIP Numbers. Pursuant to a recommendation
promulgated by the Committee on Uniform Security Identification Procedures, the
Company have caused CUSIP numbers to be printed on the Notes as a convenience to
the Holders. No representation is made as to the accuracy of such numbers as

to be bound by all of the terms and provisions of the Indenture, as the same may
be amended from time to time.
