issuance and delivery of the Debentures.  The issuance of the Debentures does
not require any further corporate action. This Agreement, the Related Agreements
and the other agreements and instruments executed by the Company in connection
herewith or therewith will each be a valid and binding obligation of the Company
enforceable in accordance with its respective terms, except as (A) the
enforceability thereof may be limited by bankruptcy, reorganization, insolvency,

Debentures will be used to purchase or carry any margin security or to extend
credit to others for the purpose of purchasing or carrying any margin security
or in any other manner which would involve a violation of any of the regulations
of the Board of Governors of the Federal Reserve System.

     2.5   Securities Statutes.  Based on the representations and warranties of

               within the meaning of the Securities Act of 1933, as amended (the
               "Securities Act").

          (ii) such Purchaser understands that none of the Debentures have been
               registered under the Securities Act or the securities laws of any

               indefinite period of time; that the exemptions from registration
               under the Securities Act provided by Rule 144 promulgated

                financial and business matters that it is capable of evaluating
                the merits and risks of this investment in the Debentures; (B)
                is able to bear the complete loss of its investment in the
                Debentures; and (C) has had the opportunity to ask questions of,
                and receive answers from, the Company

                concerning the terms and conditions of the offering of the
                Debentures and to obtain additional information.

          (iv)  such Purchaser acknowledges and agrees that until such time as
                it is no longer required under the Securities Act and the rules
                and regulations thereunder, the Debentures shall bear a legend
                referencing the Securities Act.

          (v)   such Purchaser is a financial institution or institutional buyer
                or broker-dealer within the meaning of Section 402(b)(8) of
                chapter 110A of the General Laws of Massachusetts.

endorsed, or be accompanied by a written instrument of transfer duly executed by
the holder of such Debenture or such holder's attorney duly authorized in

THIS SUBORDINATED DEBENTURE HAS NOT BEEN REGISTERED PURSUANT TO ANY FEDERAL OR

FEDERAL OR STATE SECURITIES LAWS.

    THIS INSTRUMENT IS SUBJECT TO THE SUBORDINATION AGREEMENT DATED AS OF JULY
3, 1995, AMONG THE MAKER, THE PAYEE AND THE FIRST NATIONAL BANK OF BOSTON, WHICH
AMONG OTHER THINGS, SUBORDINATES THE MAKER'S OBLIGATIONS HEREUNDER TO THE PRIOR

AS DEFINED THEREIN.

                           12% Subordinated Debenture
                               Due June 30, 2000

No. R                                                     ________, 1995


    FOR VALUE RECEIVED, Suburban Ostomy Supply Co., Inc., a Massachusetts
corporation (the "Company"), hereby promises to pay to _____________________,
or its registered assigns, the sum of _____________________ Dollars ($______)
on June 30, 2000, together with interest, computed on the basis of the actual
number of days elapsed over a 360-day year,

                                     -32-

 
on the unpaid principal balance hereof until paid in full at the rate of twelve
percent (12%) per annum from the date hereof, payable in cash quarterly in
arrears on the last day of each of March, June, September and December of each
year during which any amounts due hereunder remain outstanding, commencing on
September 30, 1995, and until such unpaid balance shall become due and payable
(whether at maturity or at a date fixed for mandatory or optional redemption or
prepayment or by acceleration or otherwise).

    In addition, in the event the principal amount of the Debenture is not paid
when due and payable (whether at stated maturity, by acceleration or otherwise),
the interest on such principal amount shall thereafter be increased to fourteen
percent (14%) per annum.  Any interest not paid when due and payable shall
thereafter be paid, on demand by the holder of this Debenture together with a
late charge of two percent (2%) of the amount of interest payment due.

    All payments of principal (including any prepayments or redemptions) and
interest hereunder shall be made by the Company in lawful money of the United
States of America in immediately available funds not later than 2:00 p.m.,
Boston time, on the date each such payment is due, by crediting an account in
the United States as the holder of this Debenture may designate in writing to
the Company before the scheduled payment date.

    This Debenture is one of a duly authorized issue of Debentures of the
Company designated as its "12% Subordinated Debentures due June 30, 2000"
(herein called the "Debentures"), in the aggregate principal amount of
$6,750,000 and issued under a Debenture Purchase Agreement, dated as of July 3,
1995 (herein called the "Agreement"), among the Company, Summit Subordinated
Debt Fund, L.P. and Summit Investors II, L.P. and certain stockholders of the
Company to which Agreement and all agreements supplemental thereto reference is
hereby made for a statement of the respective rights and duties thereunder of
the Company, and the holders of the Debentures, and the terms upon which the
Debentures are, and are to be, delivered.

    The principal of this Debenture is subject to mandatory and optional
prepayment, together with accrued interest, all as more particularly set forth
in the Agreement.  The Company agrees to make such payments of principal on the
dates and in the amounts set forth in the Agreement.

    Notwithstanding anything herein contained to the contrary, the Indebtedness
evidenced by the Debenture is, to the extent provided in the Agreement,
subordinate and subject in right of payment to the prior payment in full of all
Senior Debt as defined in the Agreement, and this Debenture is issued subject to
such provisions, and each holder of Debentures, by accepting the same, agrees to
and shall be bound by such provisions and agrees to take such action as may be
necessary or appropriate to effectuate the subordination as provided in the
Agreement.

                                     -33-

 
    In case an Event of Default, as defined in the Agreement, shall have
occurred and be continuing, the principal of all of the Debentures may be
declared, and upon such declaration shall become, due and payable, in the
manner, with the effect and subject to the conditions provided in the Agreement.
The Agreement provides that such declaration may in certain events be rescinded
or annulled by the holders of a majority in principal amount of the Debentures
then outstanding.

    No reference herein to the Agreement and no provisions of this Debenture or
of the Agreement shall alter or impair the obligation of the Company, which is
absolute and unconditional, to pay the principal of and interest on this
Debenture at the times, places, and rates, and in the coin or currency, herein
prescribed.

    As is more fully set forth in the Agreement, this Debenture is transferable
by the registered owner hereof, in person or by duly authorized attorney, on the
books of the Company to be kept for that purpose, upon surrender and
cancellation of this Debenture and upon presentation of a duly executed written
instrument of transfer satisfactory to the Company, and thereupon a new
Debenture or Debentures, of the same aggregate principal amount and in
authorized denominations, will be issued to the transferee or transferees in
exchange therefor; and this Debenture, with or without other Debentures may in
like manner be exchanged for one or more new Debentures of other authorized
denominations but of the same aggregate principal amount, all subject to the
terms and conditions set forth in the Agreement.  Any such transfer or exchange
shall be without charge by the Company.

    All terms used in this Debenture which are defined in the Agreement shall
have the meanings assigned to them in the Agreement.

    This Debenture shall be deemed to be a contract made under the laws of The
Commonwealth of Massachusetts and shall for all purposes be construed in
accordance with the laws of said Commonwealth without giving effect to the
conflict-of-laws provisions thereof.

    IN WITNESS WHEREOF, the Company has caused this Debenture to be duly
executed as a sealed instrument.

                                  SUBURBAN OSTOMY SUPPLY CO., 
                                  INC.
