ITEM 2.  ACQUISITION OR DISPOSITION OF ASSETS.
         ------------------------------------

     On August 30, 1996, PolyMedica Industries, Inc. (the "Company") completed
its acquisition (the "Acquisition") of all of the outstanding capital stock of
Liberty Medical Supply, Inc., a Florida corporation ("Liberty Medical"),
pursuant to a Stock Purchase Agreement, dated August 30, 1996 (the "Purchase
Agreement"), by and among the Company, Liberty Medical and the stockholders of
Liberty Medical.

     Pursuant to the Purchase Agreement, the Company acquired all of the
outstanding shares of capital stock of Liberty Medical for an aggregate purchase
price of $9.0 million, subject to certain adjustments based upon the financial
position of Liberty Medical on August 30, 1996 (the "Base Purchase Price"), plus
a contingent purchase price based upon Liberty Medical's future performance (the
"Contingent Purchase Price"). The Base Purchase Price was comprised of (i) $6.75
million payable in cash, by cashier's or certified check or by wire transfer of
immediately available funds, (ii) two-year, non-negotiable, unsecured,
subordinated promissory notes in the aggregate amount of $1.25 million, bearing
interest at the simple rate of 7.00% per annum, and (iii) 200,000 shares of the
Company's Common Stock. In the event that Liberty Medical's performance in any
of the calendar years ending December 31, 1997, 1998 and 1999 exceeds certain
projections for such year, certain of the stockholders of Liberty Medical will
be entitled to receive a Contingent Purchase Price up to an aggregate of $1.0
million over the three year period.

     Based upon the capitalization of the Company on August 30, 1996, the
200,000 shares of Common Stock of the Company issued to the stockholders of
Liberty Medical represent approximately 2.4% of the outstanding shares of Common
Stock of the Company. On August 30, 1996, the last reported sale price per share
of the Common Stock of the Company on the American Stock Exchange was $5.375.

     Prior to the Acquisition, Liberty Medical was engaged in the distribution
of testing supplies, medical products, and educational materials to patients
with diabetes. The Company currently intends to continue Liberty Medical's
business substantially in the manner conducted by Liberty Medical immediately
prior to the Acquisition.

     The Purchase Agreement and the Acquisition were approved by the Board of
Directors of the Company and by the Board of Directors and the stockholders of
Liberty Medical. The terms of the Purchase Agreement and the Acquisition were
determined on the basis of arm's-length negotiations. Prior to the execution of
the Purchase Agreement, neither the Company nor any of its affiliates, nor any
director or officer of the Company or any associate of any such director or
officer, had

any material relationship with Liberty Medical.

     The foregoing description of the Purchase Agreement does not purport to be
complete and is qualified in its entirety by reference to the full text of the
Purchase Agreement which is filed as Exhibit 2 to this Current Report on Form
8-K and incorporated herein by reference.

         1.5 Post-Closing Adjustments and Contingent Purchase Price.
             ------------------------------------------------------

             The Purchase Price set forth in Section 1.3 hereof shall be subject

the Company as of the Closing Balance Sheet Date. Not later than 60 days after
the Closing Balance Sheet Date, the Buyer shall deliver a balance sheet of the

Income shall be accompanied by a statement prepared by and certified by the
Buyer's chief financial officer setting forth the Contingent Purchase Price, if

<PAGE>   11



             (c)     The Buyer shall be entitled to have the balance sheet of 
the Company as of December 31, 1994 and 1995 and statements of income and cash
flow for the fiscal years then ended audited by independent public accountants
to the Buyer. The Stockholders agree to co-operate with such audit. The fees and
expenses of the accountants reasonably incurred in connection with such audit
shall be borne by the Buyer and be reimbursed by the Stockholders (in the
proportions set forth on SCHEDULE I hereof) in an amount of up to $50,000.

             (d)     Upon the calculation of the Adjustment Amount, if any, the
Purchase Price shall be adjusted (as so adjusted, the "Adjusted Purchase Price")
(i) by deducting the Adjustment Amount, if the Stockholders' Equity as of the
Closing Balance Sheet Date, without any adjustments applicable solely as a
result of the Stock Purchase by the Buyer, is less than $1,600,000 or (ii) by
adding the Adjustment Amount, if the Stockholders' Equity as of the Closing
Balance Sheet Date, without any adjustments applicable solely as a result of the
Stock Purchase by the Buyer, is greater than $1,600,000. If the Adjusted
Purchase Price is less than the Base Purchase Price, the deficiency, together
with interest thereon at the rate of 7% per annum from the Closing Date to the
payment of such deficiency, shall be paid by the Stockholders to the Buyer. Any
Adjustment Amount due to the Buyer pursuant to this Section 1.5 shall be paid to
the Buyer by the Stockholders (in the proportions set forth on SCHEDULE I
hereof), in cash, by cashier's or certified check or by wire transfer of
immediately available funds to an account designated by the Buyer. If the
Adjusted Purchase Price is greater than the Base Purchase Price, the excess
shall be paid by the Buyer to the Stockholders. Any Adjustment Amount due to the
Stockholders pursuant to this Section 1.5 shall be paid by the Buyer to the
Stockholders (in the proportions set forth on SCHEDULE I hereof), in cash, by
cashier's or certified check or by wire transfer of immediately available funds
to an account designated by each Stockholder.

             (e)     In the event that on the date 270 days after the Closing 
Date (the period prior to which and from the Closing Date is referred to herein
as the "Collection Period"), any accounts receivable of the Company remain
uncollected, the Stockholders (in the proportions set forth on SCHEDULE I
hereof) shall pay to the Buyer an amount (the "Uncollected Accounts Receivable
Amount"), if any, by which (i) the principal amount of such uncollected accounts
receivable ("Uncollected Accounts Receivable") exceeds (ii) the sum of (x) the
reserve for bad debts on the Closing Date and (y) $30,000. The Buyer shall
provide the Stockholders with a notice showing the amount of uncollected
accounts receivable and the amount due under this Section 1.5(e) and such amount
shall be payable to the Buyer within 30 days after delivery of such notice. The
Buyer agrees to cause the Company to take such reasonable collection measures as
are consistent with the Company's historical practice to collect the Company's
accounts receivable.

Libratore and Reilly. Any Contingent Purchase Price for any year shall be paid

               --------------------------------------------

<PAGE>   43



returns of, products of the Company which were sold and shipped by the Company
prior to the Closing Date to the extent that such claims exceed claims incurred
in the ordinary course of business (consistent with historical experience)
regardless of whether such claims occurred before or after the Closing Date;

                     (7)     Any liability arising out of or in connection with

Employee Plans or under COBRA, except for liabilities or obligations of the
Company for accrued vacation time, sick time and personal time for employees of
the Company (except for those employees listed on SCHEDULE 2.4 hereto) as of the
Closing Date.

              (b)    Regardless of the adequacy of any collateral or other 
means of obtaining payment of any obligation or other sum due to the Buyer from
either the Company or any Stockholder pursuant to this Section 11.2, any
adjustment to the Base Purchase Price or any other obligations expressly assumed
by the Company or the Stockholders under this Agreement (each, an "Obligation"),
the Buyer may, at any time and from time to time immediately upon a default in
the payment of any such Obligation by either the Company or any Stockholder,
without notice to the Company or the Stockholders or compliance with any other
condition precedent now or hereinafter imposed by statute, rule of law, or
otherwise (all of which are hereby expressly waived), set off, on a
dollar-for-dollar basis, any and all obligations of the Buyer or any of its
Affiliates to such defaulting person (the "Defaulting Person") (including,
without limitation, payments due under the Promissory Note and installments of
the Contingent Purchase Price as applicable to such Defaulting Person) in an
amount not to exceed the Defaulting Person's allocable portion of the Purchase
Price (except in the case of intentional or tortuous conduct), in such manner as
the Buyer in its sole discretion may determine. The Buyer shall promptly notify
the Stockholders of any exercise of the Buyer's rights under this Section
11.2(b). The foregoing set-off right of the Buyer shall be in addition to and
shall not limit in any way any right of the Buyer or any of its Affiliates to
any other remedy which may be available to it, either in law or in equity.

         11.3  CLAIMS FOR INDEMNIFICATION. Whenever any claim shall arise for
indemnification hereunder, the party seeking indemnification (the "Indemnified
Party") shall promptly notify the party from whom indemnification is sought (the


                                      -37-

<PAGE>   44



"Indemnifying Party") of the claim and, when known, the facts constituting the
basis for such claim. In the event of any such claim for indemnification
hereunder resulting from or in connection with any claim or legal proceedings by
a third-party, the notice to the Indemnifying Party shall specify, if known, the
amount or an estimate of the amount of the liability arising therefrom. The
Indemnified Party shall not settle or compromise any claim by a third party for
which it is entitled to indemnification hereunder without the prior written
consent of the Indemnifying Party, which shall not be unreasonably withheld or
delayed, unless suit shall have been instituted against the Indemnified Party
and the Indemnifying Party shall not have taken control of such suit after
notification thereof as provided in Section 11.4.

         11.4  DEFENSE BY INDEMNIFYING PARTY. In connection with any claim 
giving rise to indemnity hereunder resulting from or arising out of any claim or
legal proceeding by a person who is not a party to this Agreement, the
Indemnifying Party at its sole cost and expense may, upon written notice to the
Indemnified Party, assume the defense of any such claim or legal proceeding if
it acknowledges to the Indemnified Party in writing its obligations to indemnify
the Indemnified Party with respect to all elements of such claim. The
Indemnified Party shall be entitled to participate in (but not control) the
defense of any such action, with its counsel and at its own expense. If the
Indemnifying Party does not assume the defense of any such claim or litigation
resulting therefrom within 30 days after the date such claim is made, (a) the
Indemnified Party may defend against such claim or litigation, in such manner as
it may deem appropriate, including, but not limited to, settling such claim or
litigation, after giving notice of the same to the Indemnifying Party, on such
terms as the Indemnified Party may deem appropriate, and (b) the Indemnifying
Party shall be entitled to participate in (but not control) the defense of such
action, with its counsel and at its own expense. If the Indemnifying Party
thereafter seeks to question the manner in which the Indemnified Party defended
such third party claim or the amount or nature of any such settlement, the
Indemnifying Party shall have the burden to prove by a preponderance of the
evidence that the Indemnified Party did not defend or settle such third party
claim in a reasonably prudent manner.

         11.5  PAYMENT OF INDEMNIFICATION OBLIGATION. All indemnification 
amounts payable to any party hereto in connection with a claim for
indemnification pursuant to Section 11 hereof shall be effected by payment of
cash or delivery of a cashier's or certified check in the amount of the
indemnification liability.

         11.6  SURVIVAL OF REPRESENTATIONS; CLAIMS FOR INDEMNIFICATION. All
representations, warranties and indemnities made by the parties herein or in any
instrument or document furnished in connection herewith shall survive the
Closing and any investigation at any time made by or on behalf of the parties
hereto until the third anniversary of the Closing Date, except that:


                                      -38-

<PAGE>   45



              (i)    representations, warranties and indemnities with respect 
to the matters set forth in Sections 11.2(a)(2), (8) and (9) and Section 4.16
shall survive the Closing Date and any investigation at any time made by or on
behalf of the Indemnified Party until the expiration of any statute of
limitation with respect thereto as the same may be told or extended; and

              (ii)   representations, warranties and indemnities with respect 
to the Shares shall survive the Closing Date and any investigation at any time
made by or on behalf of the Indemnified Party for a period of ten (10) years.

     All such representations, warranties and indemnities shall expire on the
third and tenth anniversary of the Closing Date or the expiration of the statute
of limitations, as applicable, except that claims, if any, (a) asserted in
writing prior to such expiration times and identified as claims for
indemnification pursuant to this Section 11, or (b) which are based upon a
fraudulent, knowing or intentional breach by the party or parties that made the
representation, warranty, covenant or agreement, which shall survive until
resolved and satisfied in full.

         11.7  PAYMENT OF INDEMNIFICATION CLAIMS. Any amounts payable to any 
party hereto in connection with any claim for indemnification pursuant to
Section 11 hereof, shall be paid to such party immediately upon the resolution,
by agreement or arbitration, of such indemnification claim.

         11.8  LIMITATIONS ON LIABILITY FOR INDEMNITY. The preceding portions 
of this Section 11 notwithstanding, no Indemnified Party shall be indemnified
and held harmless under this Section 11 from and against Losses (except that
this limit shall not apply to any Loss relating to matters specified in Sections
11.2(a)(2), (8) and (9) or to any breach of the representations and warranties
set forth in Section 4.16 or to any breach of a representation, warranty,
covenant or agreement where such breach was made fraudulently, knowingly or
intentionally by the Buyer, the Company or the Stockholders) unless such Losses
exceed on a cumulative basis an amount equal to Fifty Thousand Dollars
($50,000), calculated on an aggregate basis with respect to the Company and the
Stockholders. The preceding portions of this Section 11 notwithstanding, the
aggregate liability of any Indemnifying Party for indemnification under this
Section 11 shall not exceed the Purchase Price paid by the Buyer to such
Indemnifying Party (except that this limit shall not apply to any Loss relating
to matters specified in Sections 11.2(a)(2), (8) and (9) or to any breach of the
representations and warranties set forth in Section 4.16 or to any breach of a
representation, warranty, covenant or agreement where such breach was made
fraudulently, knowingly or intentionally by the Buyer, the Company or the
Stockholders). For purposes of this Section 11, the amount of any Loss shall be
reduced by any insurance proceeds actually received by the Indemnified Party
with respect to such Loss.

         The Stockholders agree that from and after the Closing Date:

         12.1  Proprietary Information.
               -----------------------

              (a)    The Stockholders shall hold in confidence all knowledge 
and information of a secret or confidential nature with respect to the Business
and shall not disclose, publish or make use of the same without the consent of
the Buyer, except (i) to the extent that such information shall have become
public knowledge other than by breach of this Agreement by any Stockholder or
(ii) any Stockholder is required to disclose such information by any applicable
Law or Regulation or any court order.

              (b)    The Stockholders agree that the remedy at law for any 
breach of this Section 12.1 would be inadequate and that the Buyer shall be
entitled to injunctive relief in addition to any other remedy it may have upon
breach of any provision of this Section 12.1.

         12.2  Non-Competition Agreement.
               -------------------------

              (a)    Except as set forth in Section 12.2(b), for a period of 
five (5) years after the Closing Date or, in the case of Messrs. Libratore and
Reilly, the later of 5 years after the Closing Date and the termination of their
employment with the Buyer, neither Management Stockholder nor any Affiliate
thereof shall directly or indirectly (i) as an individual proprietor, partner,
stockholder, officer, employee, director, or in any other capacity whatsoever
(other than as the holder of not more than 1% of the total outstanding stock of
a publicly held company), engage in any business competitive with the Business
as conducted on the date hereof or on the Closing Date, in the United States or
any other country in which the Company conducted its business during the five
(5) years prior to the Closing Date; (ii) recruit, solicit or induce, or an
attempt to induce, any employee or employees of the Buyer to terminate their
employment with, or otherwise cease their relationship with, the Buyer; or (iii)
solicit, divert or take away, or attempt to divert or take away, the business or
patronage of any of the clients, customers or accounts, or prospective clients,
customers or accounts, of the Company which were contacted, solicited or served
by either Management Stockholder while employed by the Buyer.

              (b)    The Buyer agrees that (i) the direct sales (but not mail 
order sales) by A-Action Medical Supply, Inc. of diabetes supplies and equipment
shall not be deemed to violate Section 12.2(a) provided that such sales are
limited to persons, businesses or governmental agencies located in Martin and
St. Lucie counties, Florida and neither Mr. Libratore nor Mr. Reilly participate
(other than as a stockholder in A-Action Medical Supply, Inc.) in such sales and
(ii) receipt of

                                      -40-

<PAGE>   47



compensation by Messrs. Libratore and Reilly from A-Action Medical Supply, Inc.
consistent with the terms of their respective employment agreements with the
Buyer shall not be deemed to violate Section 12.2(a).

              (c)    The parties hereto agree that the duration and geographic 
scope of the non-competition provision set forth in this Section 12.2 are
reasonable. In the event that any court determines that the duration or the
geographic scope, or both, are unreasonable and that such provision is to that
extent unenforceable, the parties hereto agree that the provision shall remain
in full force and effect for the greatest time period and in the greatest area
that would not render it unenforceable. The parties intend that this
non-competition provision shall be deemed to be a series of separate covenants,
one for each and every county of each and every state of the United States of
America and each and every political subdivision of each and every country
outside the United States of America where this provision is intended to be
effective. The Management Stockholders agree that damages are an inadequate
remedy for any breach of this provision and that the Buyer shall, whether or not
it is pursuing any potential remedies at law, be entitled to equitable relief in
the form of preliminary and permanent injunctions without bond or other security
upon any actual or threatened breach of this non-competition provision.

         12.3  Sharing of Data.
               ---------------

information, correspondence, production records, employment records and other
similar information (i) of the Company for the limited purposes of complying
with their obligations under applicable securities, Tax, environmental,
employment or other Laws and Regulations and (ii) of the Buyer and its
Affiliates as are reasonably necessary to verify the calculation of the
Contingent Purchase Price.

              (b)    The Company, the Stockholders and the Buyer agree that 
from and after the Closing Date they shall cooperate fully with each other to
facilitate the transfer of the Shares from the Stockholders to the Buyer and the
operation of the Business by the Buyer.

         12.4  USE OF NAME. The Stockholders agree not to use the name "Liberty

         12.5  COOPERATION IN LITIGATION. Each party hereto will fully 
cooperate with the other in the defense or prosecution of any litigation or
proceeding already instituted or which may be instituted hereafter against or by
such party relating to or arising out of the conduct of the Business of the
Company prior to or after the Closing Date (other than litigation arising out
the transactions contemplated by this Agreement). The party requesting such
cooperation shall pay the reasonable out-of-pocket expenses (including legal
fees and disbursements) of the party providing such cooperation and of its
officers, directors, employees and agents reasonably incurred in connection with
providing such cooperation, but shall not be responsible to reimburse the party
providing such cooperation for such party's time spent in such cooperation or
the salaries or costs of fringe benefits or similar expenses paid by the party
providing such cooperation to its officers, directors, employees and agents
while assisting in the defense or prosecution of any such litigation or
proceeding.

         12.6  PRODUCT CLAIMS AND RETURNS. The Stockholders shall be responsible
for customer claims or customer warranty claims relating to goods sold and
services rendered by the Company prior to the Closing Date, and customer claims
relating to or returns of products of the Company which were sold and shipped by
the Company prior to the Closing Date to the extent such claims exceed claims
incurred in the ordinary course of the Business (consistent with historical
experience) regardless of whether such claims occur before or after the Closing
Date. If a customer makes such a claim or seeks such a return and, in the
reasonable judgment of the Buyer, such claim or return is proper, Buyer shall
replace or repair, as the case may be, the services rendered or product
purchased at the Company's then generally prevailing prices and labor rates. The
Stockholders shall promptly reimburse Buyer for the costs of such repairs and
returns of services rendered by the Company prior to the Closing Date and/or
products of the Company which were sold and shipped prior to the Closing Date
which in the aggregate exceed claims incurred in the ordinary course of the
Business (consistent with historical experience) regardless of whether such
claims occur before or after the Closing Date.

         12.7  COOPERATION WITH BUYER'S REPORTING REQUIREMENTS. The Stockholders
agree to fully cooperate with the Buyer at Buyer's sole cost and expense in

rules and regulations promulgated thereunder, as such obligations relate to the

         12.8  Repurchase of Accounts Receivable.
               ---------------------------------

              (a)    Upon the Stockholders' payment of the Uncollected Accounts
Receivable Amount, (i) the Company shall, and the Buyer shall cause the Company
to, promptly deliver to the Stockholders photocopies of any tangible evidence of
the Uncollected Accounts Receivable then in the possession of the Company or
under its control, and (ii) the Stockholders shall be entitled to take such

                                      -42-

customary and reasonable actions as are consistent with the Company's historical
practice as the Stockholders deem necessary or desirable in order to collect the
Uncollected Accounts Receivable; PROVIDED, HOWEVER, that the Stockholders shall
consult with the Company prior to taking any collection action which might
reasonably be expected to jeopardize the Company's relationship with such
customer. The Company will, and the Buyer shall cause the Company to, from time
to time after receipt of payment of the Uncollected Accounts Receivable Amount,
execute and deliver to the Stockholders such instruments and other documents as
the Stockholders may reasonably request to assist in their collection efforts,
including, without limitation, any other evidence of the transfer of title to
the Uncollected Accounts Receivable to the Stockholders.

              (b)    In the event that any payment received by the Company 
during the Collection Period is remitted by a customer which is indebted under
both Uncollected Accounts Receivable and an account receivable arising out of
the sale of inventory in the ordinary course of business after the Closing Date
(a "New Receivable"), such payments shall first be applied to the Uncollected
Accounts Receivable due from such customer, and the balance remaining after
payment in full of all Uncollected Accounts Receivable due from such customer
shall be applied to the New Receivable; PROVIDED, HOWEVER, that (i) with respect
to any Uncollected Account Receivable being contested or disputed by the payor
thereof, no portion of the amount in dispute shall be deemed to have been
collected by the Company in respect of the Uncollected Account Receivable due
from such customer (unless otherwise directed by the customer) until all amounts
owed by such customer to the Company for New Receivables have been paid or such
dispute has been resolved, whichever occurs first (it being understood that
undisputed amounts of Uncollected Accounts Receivable shall be applied in
accordance with the priorities set forth above in this Section 12.8) and (ii)
the foregoing priorities shall not apply to sums received by the Company which
are specifically identified by the customer as being tendered in payment of a
New Receivable. The Company agrees not to induce, and the Buyer shall cause the
Company not to induce, any customer to identify any payment as being in respect
of a New Receivable, except in the event the Company reasonably determines to
sell to said customer on a C.O.D. basis only.

              (c)    The Company will, and the Buyer shall cause the Company to,
cooperate, at the Stockholders' expense, with the Stockholders in collecting any
Uncollected Accounts Receivable; PROVIDED, HOWEVER, that the foregoing shall not
require the Company to be a party to any action brought by the Stockholders to
collect such Uncollected Accounts Receivable.

              (d)    The Company shall, and the Buyer shall cause the Company 
to, promptly transmit to the Stockholders any sums received by the Company in
respect of Uncollected Accounts Receivable (and so identified by the relevant
account debtor) after receipt by the Buyer of payment of the Uncollected

                                      -43-

<PAGE>   50



Accounts Receivable Amount. In addition, if receipt by the Company of
unidentified sums of money from an account debtor who owes any Uncollected
Account Receivable results in such account debtor having an aggregate credit
balance with the Company, the Company shall promptly transmit, and the Buyer
shall cause the Company promptly to transmit, to the Stockholders an amount of
money equal to the lesser of (a) such aggregate credit balance or (b) the
remaining unpaid balance of all Uncollected Accounts Receivable which are
payable by such account debtor to the Stockholders.

     13. Termination of Agreement
         ------------------------

         13.1  TERMINATION BY LAPSE OF TIME. This Agreement shall terminate at
5:00 p.m., Boston time, on September 9, 1996, if the transactions contemplated
hereby have not been consummated, unless such date is extended by the written
consent of all of the parties hereto.

         13.2  TERMINATION BY AGREEMENT OF THE PARTIES. This Agreement may be
terminated by the mutual written agreement of the parties hereto. In the event
of such termination by agreement, (a) the Buyer shall have no further obligation
or liability to the Company or the Stockholders under this Agreement; (b)
neither the Company nor the Stockholders shall have any further obligation or
liability to the Buyer under this Agreement; and (c) the preceding portions of
this Section 13.2 to the contrary notwithstanding, the provisions of Section 6.2
shall survive any such termination.

         13.3  TERMINATION BY REASON OF BREACH. This Agreement may be terminated
by the Company if at any time prior to the Closing there shall occur a breach of
any of the representations, warranties or covenants of the Buyer which is not
cured prior to the Closing or the failure by the Buyer to perform any condition
or obligation hereunder after written notice from the Company, and may be
terminated by the Buyer if at any time prior to the Closing there shall occur a

the Stockholders which is not cured prior to the Closing or the failure of the
Company or the Stockholders to perform any condition or obligation hereunder

         13.4  Liquidated Damages.
               ------------------

              (a)    The parties hereto agree that the harm suffered by the 
Buyer on the one hand and Company and the Stockholders on the other hand as a
result of a breach of this Agreement and the failure to consummate the
transactions contemplated hereby is difficult to accurately estimate. The
parties agree, based on all present circumstances, that Two Hundred Fifty
Thousand Dollars ($250,000) represents a reasonable estimate of the damages,
including lost opportunity costs,

                                      -44-

<PAGE>   51



which would be suffered by a non-breaching party upon a failure to close due to
a breach of the other party.

              (b)    In the event of a breach of any of the representations, 
warranties or covenants contained herein that is not cured or waived prior to or
at the Closing or a failure to perform any obligations or agreements required to
be performed hereunder prior to or at the Closing (a "Pre-Closing Breach") by
either party, the breaching party will pay to the non-breaching party the sum of
$250,000, as liquidated damages. The remedy set forth in this paragraph (b) is
in lieu of all other remedies available to the non-breaching party at law or in
equity for the breaching party's Pre-Closing Breach of this Agreement.

 1.  Subordination.
     -------------
   
     (a)    SUBORDINATION TO SENIOR INDEBTEDNESS. The indebtedness evidenced by
this Note, and the payment of the principal hereof, and any interest hereon, is
wholly subordinated, junior and subject in right of payment, to the extent and
in the manner hereinafter provided, to the prior payment of all Senior
Indebtedness of the Maker now outstanding or hereinafter incurred. "Senior
Indebtedness" means the principal of, and premium, if any, and interest on (i)
all indebtedness of the Maker for monies borrowed from banks, trust companies,
insurance companies and other financial institutions, including commercial paper

all indebtedness of the Maker for monies borrowed by the Maker from other
persons or entities, (iii) obligations of the Maker as lessee under leases of

described in (i), (ii), (iii) and (iv) above, and (vi) any other indebtedness of
the Maker which the Maker and the holder hereof may hereafter from time to time

Indebtedness; PROVIDED, HOWEVER, that "Senior Indebtedness" shall not mean the
principal of, and premium, if any, and interest on indebtedness or obligations
described in (i), (ii), (iii) and (iv) above which in the aggregate at any point
in time exceeds $50,000,000.

     (b)     NO PAYMENT IF DEFAULT IN SENIOR INDEBTEDNESS. No payment on account
of principal of or interest on this Subordinated Note shall be made, and this
Subordinated Note shall not be redeemed or purchased directly or indirectly by
the Maker (or any of its subsidiaries), if at the time of such payment or
purchase or immediately after giving effect thereto, (i) there shall exist a
default in any payment with respect to any Senior Indebtedness or (ii) there
shall have occurred an event of default (other than a default in the payment of
amounts due thereon) with respect to any Senior Indebtedness, as defined in the
instrument under which the same is outstanding, permitting the holders thereof
to accelerate the maturity thereof, and such event of default shall not have
been cured or waived or shall not have ceased to exist.

     (c)     Payment upon Dissolution, Etc.

             (i) In the event of any bankruptcy, insolvency, reorganization,
receivership, composition, assignment for benefit of creditors or other similar
proceeding initiated by or against the Maker or any dissolution or winding up or
total or partial liquidation or reorganization of the Maker (being hereinafter
referred to as a "Proceeding"), all claims of the holder of this Subordinated
Note in such Proceeding shall be deemed assigned, pro rata, to the then holders
of the Senior Indebtedness on the basis of the respective amounts of such Senior
Indebtedness held by each such holder, and the holder of this Subordinated Note
hereby agrees to execute all documents that such holders request in order to
evidence such assignment; PROVIDED, HOWEVER, that such assignment shall
terminate upon receipt by such holders of payment in full of all of the Senior
Indebtedness. While such assignment is in effect, the then holders of the Senior
Indebtedness shall have the exclusive right to exercise all rights of the holder
of this Subordinated Note arising from its claims in the Proceeding, including
but not limited to the right to vote for a trustee and to accept or reject a
proposed plan of reorganization or composition, and the holder of this
Subordinated Note hereby agrees to execute all documents reasonably requested by
the then holders of the Senior Indebtedness in order to exercise any such rights
whether (at the sole discretion of such holders) in the holder's own name or in
the name of the holder of this Subordinated Note. While such assignment is in
effect, any holder of this Subordinated Note also agrees that it shall, upon
request, and at its own expense take all reasonable actions (including but not
limited to the execution and filing of documents and the giving of testimony in
any Proceeding, whether or not such testimony could have been compelled by
process) necessary to prove the full amount of all its claims in any Proceeding,
and any holder of this Subordinated Note shall not expressly, by implication or
by inaction waive any claim in any Proceeding without the written consent of
such holders of Senior Indebtedness.

             (ii) Upon payment or distribution to creditors in a Proceeding of 
assets of the Maker of any kind or character, whether in cash, property or
securities, all principal and interest due upon any Senior Indebtedness shall
first be paid in full, or payment thereof in full duly provided for, before any
holder of this Subordinated Note shall be entitled to receive or, if received,
to retain any payment or distribution on account of this Subordinated Note; and
upon any such Proceeding, any payment or distribution of assets of the Maker of
any kind or character, whether in cash, property or securities, to which any
holder of this Subordinated Note would be entitled except for the provisions of
this Section 1 shall be paid by the Maker or by any receiver, trustee in
bankruptcy, liquidating trustee, agent or other person making such payment or
distribution, or by any holder of this Subordinated Note who shall have received
such


                                      -A3-

<PAGE>   59



payment or distribution, directly to the holders of the Senior Indebtedness (pro
rata to each such holder on the basis of the respective amounts of such Senior
Indebtedness held by such holder) or their representatives to the extent
necessary to pay all such Senior Indebtedness in full after giving effect to any
concurrent payment or distribution to or for the holders of such Senior
Indebtedness, before any payment or distribution is made to any holder of this
Subordinated Note. In the event of any Proceeding, the holder of this
Subordinated Note shall be entitled to be paid one hundred percent (100%) of the
principal amount hereof and accrued interest hereon and all reasonable fees and
costs due in connection herewith before any distribution of assets shall be made
among the holders of any class of shares of the capital stock of the Maker in
their capacities as holders of such shares.

             (iii)   For purposes of this Section 1(c), the words "assets" and
"cash, property or securities" shall not be deemed to include shares of Common
Stock of the Maker as reorganized or readjusted, or securities of the Maker or
any other person provided for by a plan of reorganization or readjustment, the
payment of which is subordinated at least to the extent provided in this Section
1 with respect to this Subordinated Note to the payment of all Senior
Indebtedness which may at the time be outstanding, if (x) the Senior
Indebtedness is assumed by the new entity, if any, resulting from any such
reorganization or readjustment, and (y) the rights of the holders of the Senior
Indebtedness are not, without the consent of such holders, altered by such
reorganization or readjustment.

     (d)     SUBROGATION. Subject to payment in full of all Senior Indebtedness,
any holder of this Subordinated Note shall be subrogated to the rights of the
holders of Senior Indebtedness to receive payments or distributions of the
assets of the Maker made on such Senior Indebtedness until all principal and
interest on this Subordinated Note shall be paid in full; and for purposes of
such subrogation, no payments or distributions to the holders of Senior
Indebtedness of any cash, property or securities to which any holder of this
Subordinated Note would be entitled except for the subordination provisions of
this Section 1 shall, as between the holder of this Subordinated Note and the
Maker and/or its creditors other than the holders of the Senior Indebtedness, be
deemed to be a payment on account of the Senior Indebtedness.

     (e)     RIGHTS OF HOLDERS UNIMPAIRED. The provisions of this Section 1 are
and are intended solely for the purposes of defining the relative rights of the
holder of this Subordinated Note and the holders of Senior Indebtedness and
nothing in this Section 1 shall impair, as between the Maker and any holder of
this Subordinated Note, the obligation of the Maker, which is unconditional and
absolute, to pay to the holder of this

                                      -A4-

<PAGE>   60



Subordinated Note the principal hereof and interest hereon and all other amounts
due hereunder, in accordance with the terms hereof, nor shall anything herein
prevent any holder of this Subordinated Note from exercising all remedies
otherwise permitted by applicable law or hereunder upon default, subject to the
rights set forth above of holders of Senior Indebtedness to receive cash,
property or securities otherwise payable or deliverable to the holder of this
Subordinated Note.

     (f)     HOLDERS OF SENIOR INDEBTEDNESS. The provisions of this Section 1
regarding subordination will constitute a continuing offer to all persons who,
in reliance upon such provisions, become holders of, or continue to hold, Senior
Indebtedness; such provisions are made for the benefit of the holders of Senior
Indebtedness, and such holders are hereby made obligees under such provisions to
the same extent as if they were named therein, and they or any of them may
proceed to enforce such subordination. The holder of this Subordinated Note
shall execute and deliver to any holder of Senior Indebtedness (i) any such
instrument as such holder of Senior Indebtedness may request in order to confirm
the subordination of this Note to such Senior Indebtedness upon the terms set
forth in this Subordinated Note, and (ii) any powers of attorney specifically
confirming the rights of holders of Senior Indebtedness to enforce such
subordination and all such proofs of claim, assignments of claim and other
instruments as may be requested by the holders of Senior Indebtedness or their
representatives to enforce all claims upon or in respect of this Subordinated
Note.

     (g)     PAYMENTS ON SUBORDINATED NOTE. Subject to Section 1(c), the Maker 
shall make payments of the principal of, and any interest or premium on, this
Note, if at the time of payment, and immediately after giving effect thereto,
(i) there exists no default in any payment with respect to any Senior
Indebtedness and (ii) there shall not have occurred an event of default (other
than a default in the payment of amounts due thereon) with respect to any Senior
Indebtedness, as defined in the instrument under which the same is outstanding,
permitting the holders thereof to accelerate the maturity thereof, other than an
event of default which shall have been cured or waived or shall have ceased to
exist.

2.   Redemption.
     ----------

     (a)     Subject to the subordination provisions of Section 1, this Note
may, at the option of the Maker, be called for redemption, in whole or in part

of redemption to the registered owner at his or its address as shown in the Note
Register, and the notice of redemption shall specify the date and place
designated for redemption.

     (b)     On or after the redemption date fixed in the notice of redemption,
no further interest shall accrue on the principal amount so redeemed. Payment of
the redemption price shall be made to the registered holder of this Note upon
presentation and surrender of this Note accompanied by a duly executed
instrument of transfer in blank, at the principal executive office of the Maker.

to such payment.

     Subject to the subordination provisions of Section 1, the entire unpaid
principal of this Note and the interest then accrued on this Note and all other
amounts payable hereunder shall become and be due and payable upon written
demand of the holder of this Note, without any other notice or demand of any
kind or any presentment or protest, if any one of the following events shall
occur and be continuing at the time of such demand, whether voluntarily or
involuntarily, or, without limitation, occurring or brought about by operation
of law or pursuant to or in compliance with any judgment, decree or order of any
court or any order, rule or regulation of any governmental body:

principal on this Subordinated Note, or of any installment of interest on this
Subordinated Note, and if any such default shall remain unremedied for ten (10)
days; or

     (b)     If the Maker (i) makes a composition or an assignment for the 
benefit of creditors or trust mortgage, (ii) applies for, consents to,
acquiesces in, files a petition seeking or admits (by answer, default or
otherwise) the material allegations of a petition filed against it seeking the
appointment of a trustee, receiver or liquidator, in bankruptcy or otherwise, of
itself or of all or a substantial portion of its assets, or a reorganization,
arrangement with creditors or other remedy, relief or adjudication available to
or against a bankrupt, insolvent or debtor under any bankruptcy or insolvency
law or any law affecting the rights of creditors generally, or (iii) admits in
writing its inability to pay its debts generally as they become due; or

     (c)     If an order for relief shall have been entered by a bankruptcy 
court or if a decree, order or judgment shall have been entered adjudging the
Maker insolvent, or appointing a receiver, liquidator, custodian or trustee, in
bankruptcy or otherwise, for it or for all or a substantial portion of its
assets, or approving the winding-up or liquidation of its affairs on the grounds
of insolvency or nonpayment of debts, and such order for relief, decree, order
or judgment shall remain

     -------------

     (a)     This Note is non-negotiable and may not be transferred. The Maker 
shall keep at its principal executive office a register (herein sometimes
referred to as the "Note Register"), in which, subject to such reasonable
regulations as it may prescribe, but at its expense (other than transfer taxes,
if any), the Maker shall provide for the registration of this Note.

     (b)     Upon receipt by the Maker of evidence reasonably satisfactory to 
it of the loss, theft, destruction or mutilation of this Note and of indemnity
reasonably satisfactory to it, and upon reimbursement to the Maker of all
reasonable expenses incidental thereto, and upon surrender and cancellation of
this Note (in case of mutilation) the Maker will make and deliver in lieu of
this Note a new note of like tenor and unpaid principal amount and dated as of
the date to which interest has been paid on the unpaid principal amount of this
Note in lieu of which such new note is made and delivered.

5.   Set Off.
     -------

     All payments of principal and interest on this Note shall be subject to the
Maker's right pursuant to the Stock Purchase Agreement, dated as of August 30,
1996, among the Maker, Liberty Medical Supply, Inc. and the Stockholders of
Liberty Medical Supply, Inc. identified therein to set off any amount due to the
Maker pursuant to such agreements against any amount payable under this Note.

                           REGISTRATION RIGHTS AGREEMENT
                           -----------------------------


         This Registration Rights Agreement (as amended and supplemented from
time to time, this "Agreement") dated as of August 30, 1996 is entered into by
and among PolyMedica Industries, Inc., a Massachusetts corporation (the
"Company"), Mark A. Libratore, Edward F. Reilly and Ann E. Royer (collectively,
the "Purchasers").

         WHEREAS, the Company, the Purchasers and Liberty Medical Supply, Inc.,
a Florida corporation, have entered into a Stock Purchase Agreement dated as of
August 30, 1996 (as amended and supplemented from time to time) (the "Purchase
Agreement"); and

         WHEREAS, the Company and the Purchasers desire to provide for certain
arrangements with respect to the registration of shares of capital stock of the
Company under the Securities Act (as hereinafter defined);

         NOW, THEREFORE, in consideration of the mutual promises and covenants
contained in this Agreement, the parties hereto agree as follows:

         1.  CERTAIN DEFINITIONS.  As used in this Agreement, the following 
terms shall have the following respective meanings:

             "COMMISSION" means the Securities and Exchange Commission, or any 
other Federal agency at the time administering the Securities Act.

             "COMMON STOCK" means the common stock, $0.01 par value per share, 
of the Company.

             "EXCHANGE ACT" means the Securities Exchange Act of 1934, as 
amended, or any similar Federal statute, and the rules and regulations of the
Commission issued under such Act, as they each may, from time to time, be in
effect.

             "PRIMARY SHARES" means at any time any authorized but unissued 
Common Stock, Common Stock held by the Company in its treasury or shares of
capital stock of the Company with respect to which the Company has granted
demand registration rights.

             "REGISTRATION STATEMENT" means a registration statement filed by 
the Company with the Commission for a public offering and sale of Common Stock
(other than a registration statement on Form S-8 or Form S-4, or their
successors, or any other form for a similar limited purpose, or any registration
statement covering

                                      -B1-

<PAGE>   66



only securities proposed to be issued in exchange for securities or assets of
another corporation).

             "REGISTRATION EXPENSES" has the meaning assigned to that term in 
Section 4.

             "REGISTRABLE SHARES" means (i) the shares of Common Stock issued 
to the Purchasers pursuant to the Purchase Agreement (the "Shares") and (ii) any
other shares of Common Stock issued in respect of such shares (because of stock
splits, stock dividends, reclassifications, recapitalizations, or similar
events); PROVIDED, HOWEVER, that shares of Common Stock which are Registrable
Shares shall cease to be Registrable Shares (a) upon any sale pursuant to a
Registration Statement or Rule 144 under the Securities Act or (b) upon any sale
in any manner to a person or entity which, by virtue of Section 11 of this
Agreement, is not entitled to the rights provided by this Agreement. Wherever
reference is made in this Agreement to a request or consent of holders of a
certain percentage of Registrable Shares, the determination of such percentage
shall include shares of Common Stock issuable upon conversion of the Shares even
if such conversion has not yet been effected.

             "SECURITIES ACT" means the Securities Act of 1933, as amended, or 
any similar Federal statute, and the rules and regulations of the Commission
issued under such Act, as they each may, from time to time, be in effect.


         2.  Incidental Registration.
             -----------------------

             (a)     Whenever the Company proposes to file a Registration 
Statement at any time and from time to time, it will, prior to such filing, give
written notice to all Purchasers of its intention to do so and, upon the written
request of a Purchaser or Purchasers given within 20 days after the Company
provides such notice (which request shall state the number of Registrable Shares
to be included in such Registration Statement and the intended method of
disposition of such Registrable Shares), the Company shall use its best efforts
to cause all Registrable Shares which the Company has been requested by such
Purchaser or Purchasers to register to be registered under the Securities Act to
the extent necessary to permit their sale or other disposition in accordance
with the intended methods of distribution specified in the request of such
Purchaser or Purchasers; provided that the Company shall have the right to
postpone or withdraw any registration effected pursuant to this Section 2
without obligation to any Purchaser.

             (b)     In connection with any registration under this Section 2 
involving an underwriting, the Company shall not be required to include any
Registrable Shares in such registration unless the holders thereof accept the
terms of the underwriting as agreed upon between the Company and the
underwriters selected by

                                      -B2-

<PAGE>   67



it (provided that such terms must be consistent with this Agreement). If in the
opinion of the managing underwriter it is appropriate because of marketing
factors to limit the number of Registrable Shares to be included in the
offering, then the Company shall be required to include in the registration only
that number of Registrable Shares, if any, which the managing underwriter
believes should be included therein. If the number of Registrable Shares to be
included in the offering in accordance with the foregoing is less than the total
number of shares which the holders of Registrable Shares have requested to be
included, then the number of Primary Shares, Registrable Shares and Other Shares
proposed to be included in such registration shall be included in the following
order:

            (i)      FIRST, the Primary Shares, if any; and

            (ii)     SECOND, the Registrable Shares, if any, together with
                     any other shares of capital stock of the Company with
                     respect to which the Company has granted registration
                     rights ("Other Registrable Shares"); and

            (iii)    THIRD, any shares of capital stock of the Company
                     that are not Primary Shares, Registrable Shares and
                     Other Registrable Shares.

The holders of Registrable Shares who have requested registration shall
participate in the registration pro rata based upon their total ownership of
shares of Common Stock (giving effect to the conversion into Common Stock of all
securities convertible thereto). If any holder of Registrable Shares would thus
be entitled to include more securities than such holder requested to be
registered, the excess shall be allocated among other requesting holders of
Registrable Rights pro rata in the manner described in the preceding sentence.

             (c)     DELAY PERIOD. If at any time prior to the expiration of the
effectiveness of any registration statement with respect to Registrable Shares
or prior to the filing of such registration statement, the Company determines in
good faith that the compliance by the Company with its disclosure obligations in
connection with such registration statement would require the disclosure of
material information that the Company has a bona fide business purpose for
preserving as confidential, then the Company shall not be required to file such
registration statement, maintain the effectiveness of such registration
statement or amend or supplement the applicable registration statement for a
period (an "Information Delay Period") expiring upon the earlier to occur of (i)
the date on which such material information is disclosed to the public or ceases
to be material or the Company is able to so comply with its disclosure
obligations and Commission requirements or (ii) 30 days after the Company makes
such good faith determination. Any information provided to the Purchasers
pursuant to this Section 2(c) shall be maintained in confidence by the
Purchasers.

         3.  REGISTRATION PROCEDURES.  If and whenever the Company is required
by the provisions of this Agreement to use its best efforts to effect the
registration of any of the Registrable Shares under the Securities Act, the
Company shall as expeditiously as practicable:

             (a) file with the Commission a Registration Statement with respect
to such Registrable Shares and use its best efforts to cause that Registration
Statement to become and remain effective for the period of time specified in
Section 3(c);

             (b) furnish, to one counsel selected by the Purchasers holding such
Registrable Shares (the "Purchaser's Counsel"), at least five business days
before (or two business days before, in the case of an amendment or a
supplement) filing a registration statement that registers such Registrable
Shares, (i) a prospectus relating thereto or any amendments to supplements
relating to such a registration statement or prospectus, and (ii) copies of all
such other documents proposed to be filed (it being understood that such
five-business-day and two-business day periods need not apply to successive
drafts of the same document proposed to be filed so long as such successive
drafts are supplied to Purchaser's Counsel in advance of the proposed filing by
a period of time that is customary and reasonable under the circumstances);

             (c) prepare and file with the Commission any amendments and 
supplements to the Registration Statement and the prospectus included in the
Registration Statement as may be necessary (i) to keep the Registration
Statement effective, in the case of a firm commitment underwritten public
offering, until each underwriter has completed the distribution of all
securities purchased by it and, in the case of any other offering, until the
earlier of the sale of all Registrable Shares covered thereby or 120 days after
the effective date thereof and (ii) to comply with the provisions of the
Securities Act;

             (d) furnish to each selling Purchaser such reasonable numbers of 
copies of the prospectus, including a preliminary prospectus, in conformity with
the requirements of the Securities Act, and such other documents as the selling
Purchaser may reasonably request in order to facilitate the public sale or other
disposition of the Registrable Shares owned by the selling Purchaser;

             (e) use its best efforts to register or qualify the Registrable 
Shares covered by the Registration Statement under the securities or Blue Sky
laws of such states as the selling Purchasers shall reasonably request, and do
any and all other acts and things that may be necessary or desirable to enable
the selling Purchasers to consummate the public sale or other disposition in
such states of the Registrable Shares owned by the selling Purchaser; PROVIDED,
HOWEVER, that the Company shall not be required in connection with this
paragraph (d) to qualify as a foreign corporation or execute a general consent
to service of process in any jurisdiction;


                                      -B4-

<PAGE>   69



             (f) notify Purchaser's Counsel (i) of the receipt by the Company 
of any material comments by the Commission with respect to such registration
statement or prospectus or any amendment or supplement thereto or any request by
the Commission for any material amendment or supplement thereto, (ii) of the
receipt by the Company of any stop order suspending the effectiveness of such
registration statement or prospectus or any amendment or supplement thereto or
the initiation of any proceeding for that purpose and (iii) of the receipt by
the Company of any notification of the suspension of the qualification of such
Registrable Shares for sale in any jurisdiction or the initiation of any
proceeding for such purposes;

             (g) notify the Purchasers holding such Registrable Shares at any 
time when the Company is required to maintain the effectiveness of the
Registration Statement of the happening of any event as a result of which the
prospectus included in such registration statement, as then in effect, includes
an untrue statement of a material fact or omits to state a material fact
required to be stated therein or necessary to make the statements therein, in
light of the circumstances under which they were made, not misleading and, at
the request of such Purchaser, prepare and furnish to such Purchaser a
reasonable number of copies of a supplement to or an amendment of such
prospectus as may be necessary so that, as thereafter delivered to the offerees
of such shares, such prospectus shall not include an untrue statement of a
material fact or omit to state a material fact required to be stated therein or
necessary to make the statements therein, in light or the circumstances under
which they were made, not misleading;

             (h) list such Registrable Shares on any national securities 
exchange on which the Common Stock is listed; and

             (i) make available to its security holders, as soon as reasonably
practicable, earnings statements (which need not be audited) covering a period
of 12 months beginning within three months after the last day of the calendar
quarter in which the effective date of the registration statement occurs, which
earnings statements shall satisfy the provision of Section 11(a) of the
Securities Act.

     If the Company has delivered preliminary or final prospectuses to the
selling Purchasers and after having done so the prospectus is amended, the
Company shall promptly notify the selling Purchasers and, if requested, the
selling Purchasers shall immediately cease making offers of Registrable Shares
and return all prospectuses to the Company. The Company shall promptly provide
the selling Purchasers with revised prospectuses and, following receipt of the
revised prospectuses, the selling Purchasers shall be free to resume making
offers of the Registrable Shares.

         4.  ALLOCATION OF EXPENSES. The Company will pay all Registration 
Expenses of all registrations under this Agreement. For purposes of this
Agreement, the term "Registration Expenses" shall mean all expenses incurred by
the Company in

complying with this Agreement, including, without limitation, all registration
and filing fees, exchange listing fees, printing expenses, fees and expenses of
counsel for the Company, state Blue Sky fees and expenses, and the expense of
any special audits incident to or required by any such registration, but
excluding underwriting discounts, selling commissions and the fees and expenses
of selling Purchasers' own counsel.

         5.  Indemnification and Contribution.
             --------------------------------

             (a) In the event of any registration of any of the Registrable 
Shares under the Securities Act pursuant to this Agreement, the Company will
indemnify and hold harmless the seller of such Registrable Shares, each
underwriter of such Registrable Shares, and each other person or entity, if any,
who controls such seller, underwriter within the meaning of the Securities Act
or the Exchange Act and the officers, directors and employees of each of them
against any losses, claims, damages or liabilities, joint or several, to which
such seller, underwriter or controlling person, and the officers, directors and
employees of each of them, may become subject under the Securities Act, the
Exchange Act, state securities or Blue Sky laws or otherwise, insofar as such
losses, claims, damages or liabilities (or actions in respect thereof) arise out
of or are based upon any untrue statement or alleged untrue statement of any
material fact contained in any Registration Statement under which such
Registrable Shares were registered under the Securities Act, any preliminary
prospectus or final prospectus contained in the Registration Statement or
otherwise filed with the Commission, or any amendment or supplement to such
Registration Statement, or arise out of or are based upon the omission or
alleged omission to state a material fact required to be stated therein or
necessary to make the statements therein not misleading, or any violation by the
Company of the Securities Act or state securities or blue sky laws applicable to
the Company and relating to any action or inaction required of the Company in
connection with such registration or qualification under such state securities
or blue sky laws; and the Company will reimburse such seller of Registrable
Shares, underwriter and each such controlling person, and the officers,
directors and employees of each of them, for any legal or any other expenses
(including, without limitation, reasonable attorney's fees and expenses)
reasonably incurred by any of them in connection with investigating or defending
any such loss, claim, damage, liability or action; PROVIDED, HOWEVER, that the
Company will not be liable in any such case to the extent that any such loss,
claim, damage or liability arises out of or is based upon any untrue statement
or omission made in such Registration Statement, preliminary prospectus or final
prospectus, or any such amendment or supplement, in reliance upon and in
conformity with information furnished to the Company, in writing, by or on
behalf of such seller, underwriter or controlling person specifically for use in
the preparation thereof.

<PAGE>   71



             (b) In the event of any registration of any of the Registrable 
Shares under the Securities Act pursuant to this Agreement, each seller of
Registrable Shares, severally and not jointly, will indemnify and hold harmless
the Company, each of its directors and officers and each underwriter (if any)
and each person, if any, who controls the Company or any such underwriter within
the meaning of the Securities Act or the Exchange Act, against any losses,
claims, damages or liabilities, joint or several, to which the Company, such
directors and officers, underwriter or controlling person may become subject
under the Securities Act, Exchange Act, state securities or Blue Sky laws or
otherwise, insofar as such losses, claims, damages or liabilities (or actions in
respect thereof) arise out of or are based upon any untrue statement or alleged
untrue statement of a material fact contained in any Registration Statement
under which such Registrable Shares were registered under the Securities Act,
any preliminary prospectus or final prospectus contained in the Registration
Statement, or any amendment or supplement to the Registration Statement, or
arise out of or are based upon any omission or alleged omission to state a
material fact required to be stated therein or necessary to make the statements
therein not misleading, if the statement or omission was made in reliance upon
and in conformity with information relating to such seller furnished in writing
to the Company by or on behalf of such seller specifically for use in the
preparation of such Registration Statement, prospectus, amendment or supplement;
PROVIDED, HOWEVER, that the obligations of each Purchaser under this Agreement
shall be limited to an amount equal to the net proceeds received by such
Purchaser of Registrable Shares sold pursuant to such registration.

             (c) Each party entitled to indemnification under this Section 5 
(the "Indemnified Party") shall give notice to the party required to provide
indemnification (the "Indemnifying Party") promptly after such Indemnified Party
has actual knowledge of any claim as to which indemnity may be sought, and shall
permit the Indemnifying Party to assume the defense of any such claim or any
litigation resulting therefrom; PROVIDED, that counsel for the Indemnifying
Party, who shall conduct the defense of such claim or litigation, shall be
approved by the Indemnified Party (whose approval shall not unreasonably be
withheld or delayed); and, PROVIDED, FURTHER, that the failure of any
Indemnified Party to give notice as provided herein shall not relieve the
Indemnifying Party of its obligations under this Section 5 except to the extent
that the Indemnifying Party's obligations under this Section 5 are increased by
such failure or delay in giving notice. The Indemnified Party may participate in
such defense at such party's expense; PROVIDED, HOWEVER, that the Indemnifying
Party shall pay such expense if representation of such Indemnified Party by the
counsel retained by the Indemnifying Party would be inappropriate due to actual
or potential differing interests between the Indemnified Party and any other
party represented by such counsel in such proceeding. No Indemnifying Party, in
the defense of any such claim or litigation shall, except with the consent of
each Indemnified Party, consent to entry of any judgment or enter into any
settlement which does not include as an unconditional term thereof the giving by


                                      -B7-

<PAGE>   72



the claimant or plaintiff to such Indemnified Party of a release from all
liability in respect of such claim or litigation, and no Indemnified Party shall
consent to entry of any judgment or settle such claim or litigation without the
prior written consent of the Indemnifying Party.

             (d) In order to provide for just and equitable contribution to 
joint liability under the Securities Act in any case in which either (i) any
holder of Registrable Shares exercising rights under this Agreement, or any
controlling person of any such holder, makes a claim for indemnification
pursuant to this Section 5 but it is judicially determined (by the entry of a
final judgment or decree by a court of competent jurisdiction and the expiration
of time to appeal or the denial of the last right of appeal) that such
indemnification may not be enforced in such case notwithstanding the fact that
this Section 5 provides for indemnification in such case, or (ii) contribution
under the Securities Act may be required on the part of any such selling
Purchaser or any such controlling person in circumstances for which
indemnification is provided under this Section 5; then, in each such case, the
Company and such Purchaser will contribute to the aggregate losses, claims,
damages or liabilities to which they may be subject (after contribution from
others) in such proportions so that such holder is responsible for the portion
represented by the percentage that the public offering price of its Registrable
Shares offered by the Registration Statement bears to the public offering price
of all securities offered by such Registration Statement, and the Company is
responsible for the remaining portion; PROVIDED, HOWEVER, that, in any such
case, (A) no such holder will be required to contribute any amount in excess of
the net proceeds to it of all Registrable Shares sold by it pursuant to such
Registration Statement, and (B) no person or entity guilty of fraudulent
misrepresentation, within the meaning of Section 11(f) of the Securities Act,
shall be entitled to contribution from any person or entity who is not guilty of
such fraudulent misrepresentation.

         6.  INFORMATION BY HOLDER. Each Purchaser including Registrable Shares
in any registration shall furnish to the Company such written information
regarding such Purchaser and the distribution proposed by such Purchaser as the
Company may reasonably request in writing and as shall be required in connection
with any registration, qualification or compliance referred to in this
Agreement.

         7.  "STAND-STILL" AGREEMENT.  Each Purchaser, if requested by the 
Company and the managing underwriter of an offering by the Company of Common
Stock or other securities of the Company pursuant to a Registration Statement,
shall agree not to sell publicly or otherwise transfer or dispose of any
Registrable Shares or other securities of the Company held by such Purchaser for
a specified period of time (not to exceed 90 days) following the effective date
of such Registration Statement.

         8.  RULE 144 REQUIREMENTS.  The Company agrees to:


                                      -B8-

<PAGE>   73



             (a) comply with the requirements of Rule 144(c) under the 
Securities Act with respect to current public information about the Company;

said Rule 144(c), and the reporting requirements of the Securities Act and the
Exchange Act; (ii) a copy of the most recent annual or quarterly report of the
Company, and (iii) such other reports and documents of the Company as such
holder may reasonably request to avail itself of Rule 144 or any similar rule or
regulation of the Commission allowing it to sell any such securities without
registration.

         9.  MERGERS, ETC. The Company shall not, directly or indirectly, enter
into any merger, consolidation or reorganization in which the Company shall not
be the surviving corporation unless the proposed surviving corporation shall,
prior to such merger, consolidation or reorganization, agree in writing to
assume the obligations of the Company under this Agreement, and for that purpose
references hereunder to "Registrable Shares" shall be deemed to be references to
the securities which the Purchasers would be entitled to receive in exchange for
Registrable Shares under any such merger, consolidation or reorganization;
PROVIDED, HOWEVER, that the provisions of this Section 9 shall not apply in the
event of any merger, consolidation or reorganization in which the Company is not
the surviving corporation if all Purchasers are entitled to receive in exchange
for their Registrable Shares consideration consisting solely of (i) cash, (ii)
securities of the acquiring corporation which may be immediately sold to the
public without registration under the Securities Act, or (iii) securities of the
acquiring corporation which the acquiring corporation has agreed to register
within 90 days of completion of the transaction for resale to the public
pursuant to the Securities Act.

         10. TERMINATION.  All of the Company's obligations to register 
Registrable Shares under this Agreement shall terminate on February 28, 1998.

         11. Transfers of Rights.  This Agreement, and the rights and 
obligations of the Purchasers hereunder, may not be assigned by the Purchaser to
any person or entity.

Re:      Stock Purchase Agreement, dated as of August 30, 1996, by and among
         PolyMedica Industries, Inc., Liberty Medical Supply, Inc., Mark A. 
         Libratore, Edward F. Reilly, and Ann E. Royer

Ladies and Gentlemen:

     We have acted as special counsel to Liberty Medical Supply, Inc., a Florida
corporation (the "Company"), Mark A. Libratore ("Libratore"), Edward F. Reilly
("Reilly"), and Ann E. Royer ("Royer") (collectively, such individuals are
referred to herein as the "Stockholders"), in connection with the acquisition by
PolyMedica Industries, Inc., a Massachusetts corporation ("PolyMedica"), of
1,000 shares of the Company's Common Stock, $1.00 par value per share (the
"Shares"), pursuant to that certain Stock Purchase Agreement, dated as of August
30, 1996, by and among the Company, PolyMedica, and the Stockholders (the
"Purchase Agreement"). This opinion is being provided to you pursuant to Section
9.6 of the Purchase Agreement. Capitalized terms used and not otherwise defined
herein shall have the respective meanings ascribed to them in the Purchase
Agreement.

     For purposes of this opinion, the term "Transaction Documents" means,
collectively, the Purchase Agreement, the Registration Rights Agreement, dated
as of August 30, 1996, by and among PolyMedica and each of the Stockholders (the
"Registration Rights Agreement"); the Employment Agreement, dated as of August
30, 1996, by and between PolyMedica and Libratore (the "Libratore Employment
Agreement"); and the Employment Agreement, dated as of August 30, 1996, by and
between PolyMedica and Reilly (the "Reilly Employment Agreement"). In connection
with rendering the opinions set forth below, we have examined originals (or
copies certified or otherwise identified to our satisfaction) of the Transaction
Documents and, except as may be indicated below, such other documents, corporate
records, certificates and other instruments, including stock certificates
numbers 1, 2 and 3 for the Company's shares identified in opinion


                                      -C1-

number 10 below, as we have deemed necessary or appropriate for purposes of this
opinion. In our examination, we have assumed (a) the genuineness of all
signatures, (b) the authenticity of all documents submitted to us as originals,
(c) the conformity to original documents of all documents submitted to us as
certified, conformed or photostatic copies and the authenticity of all originals
of such documents and (d) the legal capacity of all natural persons. In
rendering the opinions set forth below, we have assumed (i) the corporate or
other power and authority of all parties other than the Company and each of the
Stockholders to enter into, and perform their obligations under, the Transaction
Documents; (ii) that all parties other than the Company and each of the
Stockholders have taken all necessary corporate or other action to authorize,
execute and deliver the Transaction Documents to which they are parties; (iii)
the due authorization, execution and delivery of the Transaction Documents by
all parties thereto other than the Company and each of the Stockholders; (iv)
that each party to any Transaction Document other than the Company and each of
the Stockholders has performed and/or will perform its obligations thereunder in
accordance with the terms thereof; and (v) that the Transaction Documents are
each the valid, binding and enforceable obligation of all parties thereto other
than the Company and each of the Stockholders and are enforceable against such
parties other than the Company and each of the Stockholders in accordance with
their respective terms.

     With respect to factual matters in connection with the opinions expressed
herein, we have relied, without conducting any independent investigation, (i)
upon the accuracy of the representations and warranties contained in the
Transaction Documents, (ii) upon the certificates attached hereto as EXHIBITS
A-1, A-2, A-3 and A-4 and (iii) upon the certificates of public officials, of
officers of the Company, each of the Stockholders, and of others executed and/or
delivered in connection with the execution and delivery of the Transaction
Documents. We have made no independent investigation as to the information
contained in any of the above-described documents, but we have no reason to
believe that such information is other than as reflected therein.

     As used in this opinion, "known to us", "to our knowledge" and any similar
phrase means, and is limited, solely to the present actual knowledge, acquired
during the course of the representation described in the introductory paragraph
of this opinion, of the individual lawyers in the firm who have participated
directly in the representation of the Company and the Stockholders in connection
with the

                                      -C2-

transactions contemplated by the Transaction Documents (excluding any lawyers
whose involvement has been limited to reviewing this opinion as part of our
firm's opinion review procedure).

     As used in this opinion, the term "Person" means an individual,
partnership, limited liability company, limited liability partnership,
corporation, business trust, joint stock company, trust, unincorporated
association, joint venture, governmental authority or other entity of whatever
nature.

     Based upon the foregoing, and subject to the assumptions, limitations and
qualifications set forth herein, we are of the opinion that:

     1. The Shares have been duly authorized and validly issued and are fully
paid and nonassessable.

     2. Based solely upon the good standing certificate dated August 19, 1996,
and delivered by the Company in connection with the Closing, the Company has
been organized and exists as a corporation in good standing under the laws of
the State of Florida.

     3. The Company has full corporate power and authority to execute, deliver
and perform its obligations under the Purchase Agreement.

     4. The Purchase Agreement has been duly authorized, executed and delivered
by the Company and constitutes a legal, valid and binding agreement of the
Company.

     5. Each of the Transaction Documents to which he or she is a party has been
executed and delivered by each of the Stockholders and constitutes a legal,
valid and binding agreement of each of the Stockholders.

     6. Each of the Transaction Documents to which the Company and each of the
Stockholders is a party is enforceable against each of such Persons,
respectively, in accordance with its terms, except to the extent in each case
that enforceability of each of the Transaction Documents may be limited by (a)
bankruptcy, insolvency, reorganization, arrangement, moratorium, equitable
subordination, fraudulent conveyance or transfer, and other similar federal or
state laws and judicial decisions

of general applicability relating to or affecting creditors' or secured parties'
rights and remedies generally; (b) general principles of equity (including
without limitation concepts of materiality, reasonableness, good faith and fair
dealing and the possible unavailability of specific performance, injunctive
relief and other equitable remedies) and public policy, whether considered in an
action at law or in equity; and (c) the unenforceability under certain
circumstances under law or court decisions of provisions providing for the
indemnification of or contribution to a party with respect to a liability where
such indemnification or contribution is contrary to public policy, and PROVIDED
that we express no opinion whatsoever with respect to (x) the validity, binding
character or enforceability of any provision that purports to restrict any
Person's ability to compete with any other Person or (y) the applicability or
effect of any antitrust laws.

     7. The execution and delivery of the Transaction Documents by the Company,
the consummation by the Company of the transactions contemplated thereby and
compliance by the Company with the provisions thereof (a) will not violate any
provision of any of the Company's articles of incorporation or bylaws; (b) to
our knowledge, based solely upon EXHIBIT A-1 hereto, and except as set forth in
the Purchase Agreement and the Schedules attached thereto, violate or constitute
(or with notice or lapse of time or both constitute) a default (or give rise to
any right of termination, cancellation or acceleration) under or breach of, or
require the consent (which has not been obtained) of any Person under the terms
of, any Contract to which the Company is a party or by which any of its
properties is bound; or (c) to our knowledge, based solely upon EXHIBIT A-1
hereto, and except as set forth in the Purchase Agreement and the Schedules
attached thereto, violate any judgment, order or decree of any court or
arbitrator known to us and specifically directed to the Company or any of its
properties.

     8. The Company's authorized capitalization consists of 1,000 shares of
common stock, $1.00 par value per share.

     9. Upon payment for and delivery of the Shares with all necessary
endorsements in accordance with the terms of the Purchase Agreement, and
assuming that PolyMedica (a) has possession of the Shares; (b) is acquiring the
Shares in good faith without notice of any adverse claim; and (c) has not been a
party to any fraud or illegality affecting the Shares, PolyMedica will acquire
all the rights in the Shares that each of the Stockholders has or has actual
authority to convey, and

PolyMedica's interest in the Shares will be free of any adverse claim, except as
may be asserted by a person claiming by, through or under PolyMedica.

     10. Based solely upon our review of the stock transfer records furnished to
us by the Company, there are 1,000 shares of the Company's common stock, par
value $1.00 per share, outstanding on the date hereof. Such records indicate
that certificate number 1, representing 350 Shares, is registered in the name of
Libratore, that certificate number 2, representing 350 Shares, is registered in
the name of Reilly, and that certificate number 3, representing 300 Shares, is
registered in the name of Royer.

     We advise you that, to our knowledge, based solely upon EXHIBITS A-1, A-2,
A-3 and A-4 hereto and the representations of the Company and the Stockholders
contained in the Purchase Agreement and the Schedules thereto, and except as set
forth in the Purchase Agreement and the Schedules attached thereto, (a) there is
no litigation or other legal proceeding pending before any court, governmental
agency or arbitrator, or overtly threatened in writing against, the Company, any
of the Stockholders, or any of their respective properties; (b) there is no

                                     PARTIES
                                     -------

     This Employment Agreement (this "Agreement") dated as of the 30th day of
August, 1996, is entered into by and between PolyMedica Industries, Inc., a
Massachusetts corporation having its principal place of business at 11 State
Street, Woburn, Massachusetts 01801 (the "Company") and Mark A. Libratore, an
individual with an address at 1023 South West Catalina, Palm City, Florida 34990
(the "Executive").

                               TERMS OF AGREEMENT
                               ------------------

     In consideration of this Agreement and the continued employment of the
Executive by the Company, the parties agree as follows:

     1. EMPLOYMENT. The Company hereby employs Executive, on a full-time basis,
to act as an executive of the Company and to perform such acts and duties and
furnish such services to the Company as the Company's Chief Executive Officer or
Board of Directors shall from time to time reasonably direct. Executive shall be
the President of Liberty Medical Supply, Inc., a Florida corporation and
subsidiary of the Company ("Liberty Medical"), and Executive shall have such
responsibilities for the conduct of the business of Liberty Medical consistent
with Executive's responsibilities for the conduct of the business of Liberty
Medical prior to the date hereof. Executive hereby accepts said employment.
Executive shall faithfully and diligently promote the interests of the Company;
and shall devote his full business time and his best business judgment, skill
and knowledge to the performance of his duties and responsibilities hereunder.
Executive shall report directly to the Chief Executive Officer of the Company.
Nothing contained herein shall preclude Executive from devoting incidental and
insubstantial amounts of time to activities other than the business of the
Company.

     2. TERM OF EMPLOYMENT. The Company agrees to employ the Executive for a
three (3) year period commencing on the date hereof and ending on August 29,
1999 (the "Employment Period"). Notwithstanding the foregoing, both Executive
and the Company shall have the right to terminate the Executive's employment
under this Agreement upon thirty (30) days' written notice to the other party,
subject to the Company's obligation to pay severance benefits under certain
circumstances as provided in Section 3.6. If Executive shall remain in the
employ of the Company beyond the Employment Period, in the absence of any other
express agreement between the parties, this Agreement shall be deemed to
continue on a year-to-year basis (the "Extended Employment Period").

         3.  Compensation and Benefits; Disability.
             -------------------------------------

             3.1. SALARY. During Executive's employment, the Company shall pay 
Executive an annualized base salary of $125,000 ("Base Salary") payable in equal
installments pursuant to the Company's customary payroll policies in force at
the time of payment (but in no event less frequently than monthly), less
required payroll deductions and state and federal withholdings. Executive's Base
Salary may be adjusted upward (but not downward) from time to time in the sole
discretion of the Board of Directors of the Company, except that Executive, if a
Director, shall not be entitled to vote thereon. Executive's Base Salary shall
be reviewed annually by the Board of Directors of the Company.

             3.2. BONUS PAYMENT. During the Employment Period, Executive may 
receive, in the sole discretion of the Compensation Committee of the Board of
Directors of the Company, an annual bonus payment in an amount, if any, to be
determined by the Compensation Committee, except that Executive, if a member of
the Compensation Committee, shall not be entitled to vote thereon. If the
pre-tax earnings of Liberty Medical in any calendar year exceed the agreessive
performance targets for Liberty Medical in such year, the Compensation Committee
will consider paying the Executive an additional annual bonus payment reasonably
reflecting the results achieved by Liberty Medical.

             3.3. EXECUTIVE BENEFITS. During the Employment Period, Executive 
shall receive such benefits as are customarily provided to other officers and
employees of the Company, including but not limited to the following benefits:

             (a) HEALTH INSURANCE. Non-contributory health insurance pursuant 
to a Guardian policy or substantially similar policy; and

             (b) LIFE INSURANCE. Life insurance on the life of Executive with an
Executive-directed beneficiary in the amount of 150% of Executive's Base Salary.

             3.4. VACATION. Executive may take three weeks of paid vacation 
during each year at such times as shall be consistent with the Company's
vacation policies and (in the Company's judgment) with the Company's vacation
schedule for officers and other employees.

             3.5. DISABILITY. If during the Employment Period Executive shall 
become ill, disabled or otherwise incapacitated so as to be unable to perform
his usual duties (a) for a period in excess of one hundred twenty (120)
consecutive days or (b) for more than one hundred eighty (180) days in any
consecutive twelve (12) month period, then the Company shall have the right to
terminate this Agreement, in accordance with applicable laws, on thirty (30)
days' notice to Executive. Any dispute concerning the existence, extent or
continuance of an illness, disability or


                                     -D1-2-

<PAGE>   92



other incapacity for purposes of this Agreement shall be resolved by the
determination of a competent, independent physician selected by the Executive
and the Company.

             3.6. SEVERANCE PAY. In the event (i) the Company terminates this 
Agreement without cause (i.e., other than pursuant to Section 3.5 or Section 4
hereof) at any time (including during the Extended Employment Period), (ii)
Executive terminates his employment as a direct result of the Company, without
Executive's express written consent, demoting him to a position or assigning to
him duties inconsistent with the position and duties described in Section 1
hereof or requiring the Executive to be based in a location which would
unreasonably burden the Executive, or (iii) Executive terminates his employment
for Good Reason following a Change in Control of the Company, the Company shall
continue to pay Executive at his then current Base Salary for the first eighteen
months of the remainder of the Employment Period or for one year, whichever is
longer (the "Severance Period"). "Good Reason" shall mean, during the nine (9)
month period following a Change in Control, (1) a good faith determination by
the Executive that as a result of such Change in Control he is not able to
discharge his duties effectively or (2) without the Executive's express written
consent, the occurrence of any of the following circumstances: (a) the
assignment to Executive of any duties inconsistent (except in the nature of a
promotion) with the position in the Company that he held immediately prior to
the Change in Control or a substantial adverse alteration in the nature or
status of his position or responsibilities or the conditions of his employment
from those in effect immediately prior to the Change in Control; (b) a reduction
by the Company in Executive's annual base salary as in effect on the date hereof
or as the same may be increased from time to time; (c) the Company's requiring
the Executive to be based more than twenty-five (25) miles from the offices of
the Company or any subsidiary or affiliate of the Company at which he was
principally employed immediately prior to the date of the Change in Control
except for required travel on the Company's business to an extent substantially
consistent with his present business travel obligations; or (d) the failure by
the Company to continue in effect any material compensation or benefit plan in
which the Executive participates immediately prior to the Change in Control
unless an equitable arrangement (embodied in an ongoing substitute or
alternative plan) has been made with respect to such plan, or the failure by the
Company to continue the Executive's participation therein (or in such substitute
or alternative plan) on a basis not materially less favorable, both in terms of
the amount of benefits provided and the level of his participation relative to
other participants, than existed at the time of the Change in Control. For
purposes of this Agreement, "Change in Control" shall mean the acquisition of
beneficial ownership (as defined in Rule 13d-3 under the Securities Exchange Act
of 1934, as amended) of securities representing more than 50% of the combined
voting power of the Company's then outstanding securities except to the extent
that the directors of the Company who were directors immediately before such
Change in Control (and any directors elected by a majority of such directors)

<PAGE>   93



designate that any securities when issued by the Company shall not be counted
for purposes of determining percentages of beneficial ownership as contemplated
in this Agreement. Executive's continued employment shall not constitute consent
to, or a waiver of rights with respect to, any circumstance constituting Good
Reason hereunder.

             3.7. BENEFITS DURING SEVERANCE PERIOD. Except as otherwise 
required by law, the Executive shall not be entitled to any employee benefits
provided under Section 3.3 after termination of Executive whether or not
severance pay is being provided, except that (i) the Company shall continue in
full force and effect, at its expense, the life insurance provided for in
Section 3.3(b) for a period of one (1) year after termination of Executive's
employment hereunder or until Executive becomes employed, whichever first
occurs, and (ii) during the Severance Period, the Company shall reimburse
Executive for out-of-pocket health insurance expenses incurred by Executive
pursuant to COBRA (Consolidated Omnibus Budget Reconciliation Act of 1986). If
Executive elects not to maintain health insurance pursuant to COBRA, the Company
is under no obligation to reimburse Executive for his otherwise elected
coverage. Executive shall be obligated to give the Company prompt notice of his
employment.

         4.  DISCHARGE FOR CAUSE. The Company may discharge Executive and
terminate his employment under this Agreement for cause without further
liability to the Company by the vote of a majority vote of the Board of
Directors of the Company, except that Executive, if a Director, shall not be
entitled to vote thereon or by action of the Chief Executive Officer of the
Company. As used in this Section 4, "cause" shall mean any or all of the
following:

             (a) misconduct of Executive during the course of his employment 
which is materially injurious to the Company and which is brought to the
attention of Executive promptly after discovery by the Company, including but
not limited to theft or embezzlement from the Company, the intentional provision
of services to competitors of the Company, or improper disclosure of proprietary
information, but not including any act or failure to act by Executive which he
believed in good faith to be proper conduct not adverse to his duties hereunder;

             (b) willful disregard or neglect by Executive of his duties or of
the Company's interests which continues after being brought to the attention of
the Executive;

             (c) unavailability (except as provided in Section 3.5) of 
Executive to substantially perform the duties provided for herein;

             (d) conviction of a fraud or felony or any criminal offense 
involving dishonesty, breach of trust or moral turpitude during Executive's
employment;


                                     -D1-4-

<PAGE>   94



             (e) Executive's breach of any of the material terms of this 
Agreement (including the failure of Executive to discharge his duties in a
faithful and diligent manner) or any of the agreements executed in connection
herewith as enumerated in Section 10.1.

     In the event the Company exercises its right to terminate Executive's
employment under this Section 4, Executive shall not be entitled to receive any
severance pay or other termination benefits, except as required by law.

         5.  TERMINATION WITHOUT CAUSE. The Company may terminate this Agreement
without cause without further liability to the Company except as set forth in
Section 3.6 and 3.7 by a majority vote of the Board of Directors of the Company,
except that Executive, if a Director, shall not be entitled to vote thereon or
by action of the Chief Executive Officer of the Company.

         6.  EXPENSES.  Pursuant to the Company's customary policies in force 
at the time of payment, Executive shall be promptly reimbursed, against
presentation of vouchers or receipts therefor, for all authorized expenses
properly incurred by him on the Company's behalf in the performance of his
duties hereunder.

         7.  STOCK PURCHASE AGREEMENT & CONFIDENTIALITY AGREEMENT. The 
provisions of Section 12.2 of the Stock Purchase Agreement, dated as of August
30, 1996 (the "Stock Purchase Agreement"), among Liberty Medical Supply, Inc.,
the Company, and the stockholders of Liberty Medical named therein and
incorporated herein by reference and made a part hereof, provided that the
continued receipt by Executive from A-Action Medical Supply, Inc. of amounts
denominated as compensation shall be permitted so long as such receipt of
compensation is consistent with Section 1 hereof. Upon execution of this
Agreement, Executive shall execute and deliver to the Company the Stock Purchase
Agreement and a Confidential and Proprietary Information Agreement in the form
attached hereto as Exhibit A (collectively, the "Additional Agreements").

         8.  ARBITRATION.  All disputes and claims relating to this Agreement 
and the rights, obligations and performance of the parties hereto shall be
settled by a single arbitrator sitting in Boston, Massachusetts under the
applicable rules of the American Arbitration Association.

         9.  NOTICES. Any notice or communication given by any party hereto to
the other party or parties shall be in writing and personally delivered or
mailed by certified mail, return receipt requested, postage prepaid, to the
addresses provided above. All notices shall be deemed given when actually
received. Any person entitled to receive notice (or a copy thereof) may
designate in writing, by notice to the others, another address to which notices
to such person shall thereafter be sent.

                                  FOR EMPLOYEES
                                  -------------
               CONFIDENTIAL AND PROPRIETARY INFORMATION AGREEMENT
               --------------------------------------------------

     In consideration of my employment by PolyMedica Industries, Inc., a
Massachusetts corporation (the "Company"), I hereby agree as follows:

     1. I will make full and prompt disclosure to the Company of all inventions,
improvements, modifications, discoveries, methods, data, ideas and developments
(all of which are collectively termed "developments" hereinafter), whether
patentable or not, made or conceived or reduced to practice or learned by me
either alone or jointly with others or under my direction during the period of
my employment, whether or not made or conceived during normal working hours or
on the premises of the Company or any subsidiary or affiliate of the Company. I
do not have any developments other than those I have already disclosed to you.

     2. I agree that all developments covered by Paragraph 1 shall be the sole
property of the Company and its assigns, and the Company and its assigns shall
be the sole owner of all patents and other rights in connection therewith. I
hereby assign to the Company any rights I may have or acquire in all
developments. I further agree as to all developments to assist the Company in
every proper way (but at the Company's expense) to obtain and from time to time
enforce patents on developments in any and all countries, and to that end I will
execute all documents for use in applying for and obtaining such patents thereon
and enforcing same, as the Company may desire, together with any assignments
thereof to the Company or persons designated by it. My obligation to assist the
Company in obtaining and enforcing patents for developments in any and all
countries shall continue beyond the termination of my employment, but the
Company shall compensate me at a reasonable rate after such termination for time
actually spent by me at the Company's request on such assistance.

     I understand that this Paragraph 2 does not apply to (i) developments for
which no equipment, supplies, facility or trade secret information of the
Company was used and which was developed entirely on my own time, and (a) which
does not relate (1) to the business of the Company or any subsidiary or
affiliate of the Company or (2) to the actual or demonstrable anticipated
research or development of the Company or any subsidiary or affiliate of the
Company, and (b) which does not result from any work performed by me for the
Company or any subsidiary or affiliate of the Company, and (ii) any other
developments which I have brought to the Company's attention in writing and
which the Company has declined in writing to utilize or practice.


                                     -D1-9-

<PAGE>   99



     3. I hereby represent that, to the best of my knowledge, I have no present
obligation to assign to any former employer or any other person, corporation or
firm, any developments covered by Paragraph 2. I represent that my performance
of all the terms of this Agreement and as an employee of the Company does not
and will not breach any agreement to keep in confidence proprietary information
acquired by me in confidence or in trust prior to my employment by the Company.
I have not entered into, and I agree I will not enter into, any agreement
(either written or oral) in conflict herewith.

     4. I will also assign to the Company any and all copyrights and
reproduction rights to any material prepared by me in connection with my
employment.

     5. I understand as part of the consideration for the offer of employment
extended to me by the Company and of my employment or continued employment by
the Company, that I have not brought and will not bring with me to the Company
or use in the performance of my responsibilities at the Company any materials or
documents of a former employer which are not generally available to the public,
unless I have obtained written authorization from the former employer for their
possession and use.

     Accordingly, this is to advise the Company that the only materials or
documents of a former employer which are not generally available to the public
that I have brought or will bring to the Company or have used or will use in my
employment are identified on Exhibit B attached hereto, and, as to each such
item, I represent that I have obtained prior to the effective date of my
employment with the Company written authorization for their possession and use
in my employment with the Company.

     6. During the course of my employment by the Company, I may learn of the
confidential information of the Company or a subsidiary or affiliate of the
Company or confidential information entrusted to the Company by other persons,
corporations, or firms. The Company's confidential information includes matters
not generally known outside the Company, such as developments relating to
existing and future products and services marketed or used by the Company and
data relating to the general business operations of the Company (e.g.,
concerning sales, costs, profits, organizations, customer lists, pricing
methods, etc.). I agree not to disclose any confidential information of the
Company or of such other persons, corporations, or firms to others or to make
use of it, except on the Company's behalf, whether or not such information is
produced by my own efforts. Also, I may learn of developments, ways of business,
etc., which in themselves are generally known but whose use by the Company is
not generally known, and I agree not to disclose to others such use, whether or
not such use is due to my own efforts.

     7. At the time I begin my employment and during the term of my employment
by the Company, except as otherwise provided by my Employment Agreement with the
Company or the Stock Purchase Agreement between myself, the Company, Liberty
Medical Supply, Inc. and the other stockholders of Liberty Medical Supply, Inc.,
I will not become employed by or act on behalf of any other person, corporation,
or firm which is engaged in any business or activity similar to or competitive
with that of the Company, unless such employment has been approved by the
Company in writing and signed by an appropriate personnel manager of the
Company.

     8. In the event that my employment is transferred by the Company to a
subsidiary or affiliated company (as the case may be), my employment by such
company will, for the purposes of this Agreement, be considered as continued
employment by the Company, unless I execute an agreement substantially similar
in substance to this Agreement, in which event my employment by the Company
shall be deemed to continue until the effective date of said agreement in any
such company for which I become employed.

     9. I hereby give the Company and its assigns permission to reasonably use
photographs of me, either during or after my employment, with or without using
my name, for whatever purposes it deems necessary.

     10. Upon termination of my employment, unless my employment is transferred
to a subsidiary or affiliated company of the Company, I agree to leave with the
Company all records, drawings, notebooks, and other documents pertaining to the
Company's confidential information, whether prepared by me or others, and also
any equipment, tools or other devices owned by the Company, then in my
possession however such items are obtained, and I agree not to reproduce any
document or data relating thereto. The preceding portions of this Paragraph 10
to the contrary notwithstanding, upon any termination of my employment, I shall
be entitled to remove from the Company's premises all of my personal items and
effects that do not contain any of the Company's confidential information.

     11. My obligations under this Agreement shall survive the termination of my
employment regardless of the manner of such termination, and shall be binding
upon my heirs, executors, and administrators.

     12. Prior to entering the employ of the Company I have terminated
employment with all past employers.

     13. As a matter of record I have identified on Exhibit A attached hereto
all developments relevant to the subject matter of my employment by the Company
which have been made or conceived or first reduced to practice by me alone or
jointly with others prior to my engagement by the Company which I desire to


                                     -D1-11-

<PAGE>   101



remove from the operation of the Agreement; and I covenant that such list is
complete. If there is no such list on Exhibit B, I represent that I have made no
such developments at the time of signing this Agreement.

     14. I agree that in addition to any other rights and remedies available to
the Company for any breach by me of my obligations hereunder, the Company shall
be entitled to enforcement of my obligations hereunder by court injunction.

     15. If any provision of this Agreement shall be declared invalid, illegal
or unenforceable, then such provision shall be enforceable to the extent that a
court shall deem it reasonable to enforce to any extent, such provision shall be
severed and all remaining provisions shall continue in full force and effect.

     16. This Agreement shall be effective as of the date set forth below next
to my signature.

     17. This Agreement shall be governed in all respects by the laws of the
Commonwealth of Massachusetts.

                                     PARTIES
                                     -------

     This Employment Agreement (this "Agreement") dated as of the 30th day of
August, 1996, is entered into by and between PolyMedica Industries, Inc., a
Massachusetts corporation having its principal place of business at 11 State
Street, Woburn, Massachusetts 01801 (the "Company") and Edward F. Reilly, an
individual with an address at 73 South Sewalls Point Road, Stuart, Florida 34996
(the "Executive").

                               TERMS OF AGREEMENT
                               ------------------

     In consideration of this Agreement and the continued employment of the
Executive by the Company, the parties agree as follows:

     1.  EMPLOYMENT. The Company hereby employs Executive, on a full-time basis,
to act as an executive of the Company and to perform such acts and duties and
furnish such services to the Company as the Company's Chief Executive Officer or
Board of Directors shall from time to time reasonably direct. Executive shall be
the Vice President of Liberty Medical Supply, Inc., a Florida corporation and
subsidiary of the Company ("Liberty Medical"), and Executive shall have such
responsibilities for the conduct of the business of Liberty Medical consistent
with Executive's responsibilities for the conduct of the business of Liberty
Medical prior to the date hereof. Executive hereby accepts said employment.
Executive shall faithfully and diligently promote the interests of the Company;
and shall devote his full business time and his best business judgment, skill
and knowledge to the performance of his duties and responsibilities hereunder.
Executive shall report directly to the Chief Executive Officer of the Company.
Nothing contained herein shall preclude Executive from devoting incidental and
insubstantial amounts of time to activities other than the business of the
Company.

     2.  TERM OF EMPLOYMENT. The Company agrees to employ the Executive for a
three (3) year period commencing on the date hereof and ending on August 29,
1999 (the "Employment Period"). Notwithstanding the foregoing, both Executive
and the Company shall have the right to terminate the Executive's employment
under this Agreement upon thirty (30) days' written notice to the other party,
subject to the Company's obligation to pay severance benefits under certain
circumstances as provided in Section 3.6. If Executive shall remain in the
employ of the Company beyond the Employment Period, in the absence of any other
express agreement between the parties, this Agreement shall be deemed to
continue on a year-to-year basis (the "Extended Employment Period").

<PAGE>   104



     3.  Compensation and Benefits; Disability.
         -------------------------------------

         3.1. SALARY. During Executive's employment, the Company shall pay 
Executive an annualized base salary of $100,000 ("Base Salary") payable in equal
installments pursuant to the Company's customary payroll policies in force at
the time of payment (but in no event less frequently than monthly), less
required payroll deductions and state and federal withholdings. Executive's Base
Salary may be adjusted upward (but not downward) from time to time in the sole
discretion of the Board of Directors of the Company, except that Executive, if a
Director, shall not be entitled to vote thereon. Executive's Base Salary shall
be reviewed annually by the Board of Directors of the Company.

         3.2. BONUS PAYMENT. During the Employment Period, Executive may 
receive, in the sole discretion of the Compensation Committee of the Board of
Directors of the Company, an annual bonus payment in an amount, if any, to be
determined by the Compensation Committee, except that Executive, if a member of
the Compensation Committee, shall not be entitled to vote thereon. If the
pre-tax earnings of Liberty Medical in any calendar year exceed the agreessive
performance targets for Liberty Medical in such year, the Compensation Committee
will consider paying the Executive an additional annual bonus payment reasonably
reflecting the results achieved by Liberty Medical.

         3.3. EXECUTIVE BENEFITS. During the Employment Period, Executive shall
receive such benefits as are customarily provided to other officers and
employees of the Company, including but not limited to the following benefits:

         (a) HEALTH INSURANCE. Non-contributory health insurance pursuant to a
Guardian policy or substantially similar policy; and

         (b) LIFE INSURANCE. Life insurance on the life of Executive with an
Executive-directed beneficiary in the amount of 150% of Executive's Base Salary.

         3.4. VACATION. Executive may take three weeks of paid vacation during 
each year at such times as shall be consistent with the Company's vacation
policies and (in the Company's judgment) with the Company's vacation schedule
for officers and other employees.

         3.5. DISABILITY. If during the Employment Period Executive shall become
ill, disabled or otherwise incapacitated so as to be unable to perform his usual
duties (a) for a period in excess of one hundred twenty (120) consecutive days
or (b) for more than one hundred eighty (180) days in any consecutive twelve
(12) month period, then the Company shall have the right to terminate this
Agreement, in accordance with applicable laws, on thirty (30) days' notice to
Executive. Any dispute concerning the existence, extent or continuance of an
illness, disability or


                                     -D2-2-

<PAGE>   105



other incapacity for purposes of this Agreement shall be resolved by the
determination of a competent, independent physician selected by the Executive
and the Company.

         3.6. SEVERANCE PAY. In the event (i) the Company terminates this 
Agreement without cause (i.e., other than pursuant to Section 3.5 or Section 4
hereof) at any time (including during the Extended Employment Period), (ii)
Executive terminates his employment as a direct result of the Company, without
Executive's express written consent, demoting him to a position or assigning to
him duties inconsistent with the position and duties described in Section 1
hereof or requiring the Executive to be based in a location which would
unreasonably burden the Executive, or (iii) Executive terminates his employment
for Good Reason following a Change in Control of the Company, the Company shall
continue to pay Executive at his then current Base Salary for the first eighteen
months of the remainder of the Employment Period or for one year, whichever is
longer (the "Severance Period"). "Good Reason" shall mean, during the nine (9)
month period following a Change in Control, (1) a good faith determination by
the Executive that as a result of such Change in Control he is not able to
discharge his duties effectively or (2) without the Executive's express written
consent, the occurrence of any of the following circumstances: (a) the
assignment to Executive of any duties inconsistent (except in the nature of a
promotion) with the position in the Company that he held immediately prior to
the Change in Control or a substantial adverse alteration in the nature or
status of his position or responsibilities or the conditions of his employment
from those in effect immediately prior to the Change in Control; (b) a reduction
by the Company in Executive's annual base salary as in effect on the date hereof
or as the same may be increased from time to time; (c) the Company's requiring
the Executive to be based more than twenty-five (25) miles from the offices of
the Company or any subsidiary or affiliate of the Company at which he was
principally employed immediately prior to the date of the Change in Control
except for required travel on the Company's business to an extent substantially
consistent with his present business travel obligations; or (d) the failure by
the Company to continue in effect any material compensation or benefit plan in
which the Executive participates immediately prior to the Change in Control
unless an equitable arrangement (embodied in an ongoing substitute or
alternative plan) has been made with respect to such plan, or the failure by the
Company to continue the Executive's participation therein (or in such substitute
or alternative plan) on a basis not materially less favorable, both in terms of
the amount of benefits provided and the level of his participation relative to
other participants, than existed at the time of the Change in Control. For
purposes of this Agreement, "Change in Control" shall mean the acquisition of
beneficial ownership (as defined in Rule 13d-3 under the Securities Exchange Act
of 1934, as amended) of securities representing more than 50% of the combined
voting power of the Company's then outstanding securities except to the extent
that the directors of the Company who were directors immediately before such
Change in Control (and any directors elected by a majority of such directors)

<PAGE>   106



designate that any securities when issued by the Company shall not be counted
for purposes of determining percentages of beneficial ownership as contemplated
in this Agreement. Executive's continued employment shall not constitute consent
to, or a waiver of rights with respect to, any circumstance constituting Good
Reason hereunder.

         3.7. BENEFITS DURING SEVERANCE PERIOD. Except as otherwise required by 
law, the Executive shall not be entitled to any employee benefits provided under
Section 3.3 after termination of Executive whether or not severance pay is being
provided, except that (i) the Company shall continue in full force and effect,
at its expense, the life insurance provided for in Section 3.3(b) for a period
of one (1) year after termination of Executive's employment hereunder or until
Executive becomes employed, whichever first occurs, and (ii) during the
Severance Period, the Company shall reimburse Executive for out-of-pocket health
insurance expenses incurred by Executive pursuant to COBRA (Consolidated Omnibus
Budget Reconciliation Act of 1986). If Executive elects not to maintain health
insurance pursuant to COBRA, the Company is under no obligation to reimburse
Executive for his otherwise elected coverage. Executive shall be obligated to
give the Company prompt notice of his employment.

         4.  DISCHARGE FOR CAUSE. The Company may discharge Executive and
terminate his employment under this Agreement for cause without further
liability to the Company by the vote of a majority vote of the Board of
Directors of the Company, except that Executive, if a Director, shall not be
entitled to vote thereon or by action of the Chief Executive Officer of the
Company. As used in this Section 4, "cause" shall mean any or all of the
following:

             (a) misconduct of Executive during the course of his employment 
which is materially injurious to the Company and which is brought to the
attention of Executive promptly after discovery by the Company, including but
not limited to theft or embezzlement from the Company, the intentional provision
of services to competitors of the Company, or improper disclosure of proprietary
information, but not including any act or failure to act by Executive which he
believed in good faith to be proper conduct not adverse to his duties hereunder;

             (b) willful disregard or neglect by Executive of his duties or of 
the Company's interests which continues after being brought to the attention of
the Executive;

             (c) unavailability (except as provided in Section 3.5) of 
Executive to substantially perform the duties provided for herein;

             (d) conviction of a fraud or felony or any criminal offense 
involving dishonesty, breach of trust or moral turpitude during Executive's
employment;


                                     -D2-4-

<PAGE>   107



             (e) Executive's breach of any of the material terms of this 
Agreement (including the failure of Executive to discharge his duties in a
faithful and diligent manner) or any of the agreements executed in connection
herewith as enumerated in Section 10.1.

     In the event the Company exercises its right to terminate Executive's
employment under this Section 4, Executive shall not be entitled to receive any
severance pay or other termination benefits, except as required by law.

     5. TERMINATION WITHOUT CAUSE. The Company may terminate this Agreement
without cause without further liability to the Company except as set forth in
Section 3.6 and 3.7 by a majority vote of the Board of Directors of the Company,
except that Executive, if a Director, shall not be entitled to vote thereon or
by action of the Chief Executive Officer of the Company.

     6. EXPENSES. Pursuant to the Company's customary policies in force at the
time of payment, Executive shall be promptly reimbursed, against presentation of
vouchers or receipts therefor, for all authorized expenses properly incurred by
him on the Company's behalf in the performance of his duties hereunder.

     7. STOCK PURCHASE AGREEMENT & CONFIDENTIALITY AGREEMENT. The provisions of
Section 12.2 of the Stock Purchase Agreement, dated as of August 30, 1996 (the
"Stock Purchase Agreement"), among Liberty Medical Supply, Inc., the Company,
and the stockholders of Liberty Medical named therein and incorporated herein by
reference and made a part hereof, provided that the continued receipt by
Executive from A-Action Medical Supply, Inc. of amounts denominated as
compensation shall be permitted so long as such receipt of compensation is
consistent with Section 1 hereof. Upon execution of this Agreement, Executive
shall execute and deliver to the Company the Stock Purchase Agreement and a
Confidential and Proprietary Information Agreement in the form attached hereto
as Exhibit A (collectively, the "Additional Agreements").

     8. ARBITRATION. All disputes and claims relating to this Agreement and the
rights, obligations and performance of the parties hereto shall be settled by a
single arbitrator sitting in Boston, Massachusetts under the applicable rules of
the American Arbitration Association.

     9. NOTICES. Any notice or communication given by any party hereto to the
other party or parties shall be in writing and personally delivered or mailed by
certified mail, return receipt requested, postage prepaid, to the addresses
provided above. All notices shall be deemed given when actually received. Any
person entitled to receive notice (or a copy thereof) may designate in writing,
by notice to the others, another address to which notices to such person shall
thereafter be sent.

waiver of any breach of any provision of this Agreement shall be deemed to be a
waiver of any preceding or succeeding breach of the same or any other provision.

             10.3. BINDING EFFECT; ASSIGNMENT. The rights and obligations of 
this Agreement shall bind and inure to the benefit of any successor of the
Company by reorganization, merger or consolidation, or any assignee of all or
substantially all of the Company's business and properties. Executive's rights
or obligations under this Agreement may not be assigned by Executive; except
that Executive's right to compensation to the earlier of date of death or
termination of actual employment shall pass to Executive's executor or
administrator.

             10.4. HEADINGS. The headings contained in this Agreement are for 
reference purposes only and shall not affect the meaning or interpretation of

             10.5. GOVERNING LAW; Interpretation. This Agreement shall be 
construed in accordance with and governed for all purposes by the laws and
public policy of the Commonwealth of Massachusetts applicable to contracts

                                    ---------


                                  FOR EMPLOYEES
                                  -------------
               CONFIDENTIAL AND PROPRIETARY INFORMATION AGREEMENT
               --------------------------------------------------

     In consideration of my employment by PolyMedica Industries, Inc., a
Massachusetts corporation (the "Company"), I hereby agree as follows:

     1. I will make full and prompt disclosure to the Company of all inventions,
improvements, modifications, discoveries, methods, data, ideas and developments
(all of which are collectively termed "developments" hereinafter), whether
patentable or not, made or conceived or reduced to practice or learned by me
either alone or jointly with others or under my direction during the period of
my employment, whether or not made or conceived during normal working hours or
on the premises of the Company or any subsidiary or affiliate of the Company. I
do not have any developments other than those I have already disclosed to you.

     2. I agree that all developments covered by Paragraph 1 shall be the sole
property of the Company and its assigns, and the Company and its assigns shall
be the sole owner of all patents and other rights in connection therewith. I
hereby assign to the Company any rights I may have or acquire in all
developments. I further agree as to all developments to assist the Company in
every proper way (but at the Company's expense) to obtain and from time to time
enforce patents on developments in any and all countries, and to that end I will
execute all documents for use in applying for and obtaining such patents thereon
and enforcing same, as the Company may desire, together with any assignments
thereof to the Company or persons designated by it. My obligation to assist the
Company in obtaining and enforcing patents for developments in any and all
countries shall continue beyond the termination of my employment, but the
Company shall compensate me at a reasonable rate after such termination for time
actually spent by me at the Company's request on such assistance.

     I understand that this Paragraph 2 does not apply to (i) developments for
which no equipment, supplies, facility or trade secret information of the
Company was used and which was developed entirely on my own time, and (a) which
does not relate (1) to the business of the Company or any subsidiary or
affiliate of the Company or (2) to the actual or demonstrable anticipated
research or development of the Company or any subsidiary or affiliate of the
Company, and (b) which does not result from any work performed by me for the
Company or any subsidiary or affiliate of the Company, and (ii) any other
developments which I have brought to the Company's attention in writing and
which the Company has declined in writing to utilize or practice.


                                     -D2-9-

<PAGE>   112



     3. I hereby represent that, to the best of my knowledge, I have no present
obligation to assign to any former employer or any other person, corporation or
firm, any developments covered by Paragraph 2. I represent that my performance
of all the terms of this Agreement and as an employee of the Company does not
and will not breach any agreement to keep in confidence proprietary information
acquired by me in confidence or in trust prior to my employment by the Company.
I have not entered into, and I agree I will not enter into, any agreement
(either written or oral) in conflict herewith.

     4. I will also assign to the Company any and all copyrights and
reproduction rights to any material prepared by me in connection with my
employment.

     5. I understand as part of the consideration for the offer of employment
extended to me by the Company and of my employment or continued employment by
the Company, that I have not brought and will not bring with me to the Company
or use in the performance of my responsibilities at the Company any materials or
documents of a former employer which are not generally available to the public,
unless I have obtained written authorization from the former employer for their
possession and use.

     Accordingly, this is to advise the Company that the only materials or
documents of a former employer which are not generally available to the public
that I have brought or will bring to the Company or have used or will use in my
employment are identified on Exhibit B attached hereto, and, as to each such
item, I represent that I have obtained prior to the effective date of my
employment with the Company written authorization for their possession and use
in my employment with the Company.

     6. During the course of my employment by the Company, I may learn of the
confidential information of the Company or a subsidiary or affiliate of the
Company or confidential information entrusted to the Company by other persons,
corporations, or firms. The Company's confidential information includes matters
not generally known outside the Company, such as developments relating to
existing and future products and services marketed or used by the Company and
data relating to the general business operations of the Company (e.g.,
concerning sales, costs, profits, organizations, customer lists, pricing
methods, etc.). I agree not to disclose any confidential information of the
Company or of such other persons, corporations, or firms to others or to make
use of it, except on the Company's behalf, whether or not such information is
produced by my own efforts. Also, I may learn of developments, ways of business,
etc., which in themselves are generally known but whose use by the Company is
not generally known, and I agree not to disclose to others such use, whether or
not such use is due to my own efforts.


                                     -D2-10-

<PAGE>   113



     7. At the time I begin my employment and during the term of my employment
by the Company, except as otherwise provided by my Employment Agreement with the
Company or the Stock Purchase Agreement between myself, the Company, Liberty
Medical Supply, Inc. and the other stockholders of Liberty Medical Supply, Inc.,
I will not become employed by or act on behalf of any other person, corporation,
or firm which is engaged in any business or activity similar to or competitive
with that of the Company, unless such employment has been approved by the
Company in writing and signed by an appropriate personnel manager of the
Company.

     8. In the event that my employment is transferred by the Company to a
subsidiary or affiliated company (as the case may be), my employment by such
company will, for the purposes of this Agreement, be considered as continued
employment by the Company, unless I execute an agreement substantially similar
in substance to this Agreement, in which event my employment by the Company
shall be deemed to continue until the effective date of said agreement in any
such company for which I become employed.

     9. I hereby give the Company and its assigns permission to reasonably use
photographs of me, either during or after my employment, with or without using
my name, for whatever purposes it deems necessary.

     10. Upon termination of my employment, unless my employment is transferred
to a subsidiary or affiliated company of the Company, I agree to leave with the
Company all records, drawings, notebooks, and other documents pertaining to the
Company's confidential information, whether prepared by me or others, and also
any equipment, tools or other devices owned by the Company, then in my
possession however such items are obtained, and I agree not to reproduce any
document or data relating thereto. The preceding portions of this Paragraph 10
to the contrary notwithstanding, upon any termination of my employment, I shall
be entitled to remove from the Company's premises all of my personal items and
effects that do not contain any of the Company's confidential information.

     11. My obligations under this Agreement shall survive the termination of my
employment regardless of the manner of such termination, and shall be binding
upon my heirs, executors, and administrators.

     12. Prior to entering the employ of the Company I have terminated
employment with all past employers.

     13. As a matter of record I have identified on Exhibit A attached hereto
all developments relevant to the subject matter of my employment by the Company
which have been made or conceived or first reduced to practice by me alone or
jointly with others prior to my engagement by the Company which I desire to


                                     -D2-11-

<PAGE>   114



remove from the operation of the Agreement; and I covenant that such list is
complete. If there is no such list on Exhibit B, I represent that I have made no
such developments at the time of signing this Agreement.

     14. I agree that in addition to any other rights and remedies available to
the Company for any breach by me of my obligations hereunder, the Company shall
be entitled to enforcement of my obligations hereunder by court injunction.

     15. If any provision of this Agreement shall be declared invalid, illegal
or unenforceable, then such provision shall be enforceable to the extent that a
court shall deem it reasonable to enforce to any extent, such provision shall be
severed and all remaining provisions shall continue in full force and effect.

     16. This Agreement shall be effective as of the date set forth below next
to my signature.

     17. This Agreement shall be governed in all respects by the laws of the
Commonwealth of Massachusetts.

                  Liberty Medical Supply, Inc.
                  ----------------------------------------------------------

Gentlemen:

     This opinion is furnished pursuant to Section 10.6 of the Stock Purchase
Agreement dated as of August 30, 1996 (the "Agreement") by and among PolyMedica
Industries, Inc., a Massachusetts corporation (the "Buyer"), Liberty Medical
Supply, Inc., a Florida corporation ("Liberty Medical"), and Mark A. Libratore,
Edward F. Reilly and Ann E. Royer (the "Stockholders"). Capitalized terms not
otherwise defined herein have the respective meanings ascribed to them in the
Agreement.

     We have acted as counsel to the Buyer in connection with the Agreement,
providing for the purchase by the Buyer of all of the outstanding shares of
capital stock of Liberty Medical (the "Acquired Shares"). As such counsel, we
have assisted in the preparation of the Agreement, the Promissory Notes, the
Employment Agreements and the Registration Rights Agreement (the "Buyer's
Documents").

     We have also examined and are familiar with and have relied upon the
following documents:

     (a)  The Articles of Organization and Bylaws, as amended, of the Buyer;

     (b)  A certificate, dated as of August 28, 1996, of the Secretary of State
          of The Commonwealth of Massachusetts certifying to the legal existence
          and the good standing of the Buyer in The Commonwealth of
          Massachusetts;

     (c)  Resolutions of the Board of Directors of the Buyer approving the
          purchase by the Buyer of the Acquired Shares and authorizing, among


                                      -E-1-

<PAGE>   117



          other things, the execution, delivery and performance by the Buyer of
          the Buyer's Documents; and

     (d)  Such other documents, instruments and certificates (including, but not
          limited to, certificates of public officials and officers of the
          Buyer) as we have considered necessary for purposes of this opinion.

     In our examination of the documents described above, we have assumed the
genuineness of all signatures, the completeness of all corporate records
provided to us, the authenticity of all documents submitted to us as originals,
the conformity to original documents of all documents submitted to us as
certified, photostatic or facsimile copies, the authenticity of the originals of
such latter documents and the legal competence of all signatories to such
documents.

     In rendering this opinion, we have relied, as to all questions of fact
material to this opinion, upon certificates of public officials and officers of
the Buyer and upon the representations and warranties made by the Buyer in the
Agreement. We have not attempted to verify independently such facts, although
nothing has come to our attention which would lead us to question the accuracy
of such certificates or representations and warranties.

     For purposes of this opinion, we have assumed that each of the Buyer's
Documents has been duly authorized, executed and delivered by all parties
thereto other than the Buyer and that all such parties have all requisite power,
authority and capacity to effect the transactions contemplated by the Buyer's
Documents. We have also assumed that each of the Buyer's Documents is the valid
and binding obligation of each party thereto other than the Buyer, enforceable
against all such parties in accordance with its terms. We do not render any
opinion as to the application of any federal or state law or regulation to the
power, authority or competence of any party to the Buyer's Documents other than
the Buyer.

     Our opinions set forth below are qualified to the extent that they may be
subject to or affected by (i) applicable bankruptcy, insolvency, reorganization,
fraudulent conveyance or transfer, moratorium or similar laws relating to or
affecting the rights and remedies of creditors generally, (ii) statutory or
decisional law concerning recourse by creditors to security in the absence of
notice or hearing and (iii) duties and standards imposed on creditors and
parties to contracts, including, without limitation, requirements of good faith,
reasonableness and fair dealing. Furthermore, we express no opinion as to the
availability of any equitable or specific remedy upon any breach of the Buyer's
Documents or any of the agreements, documents or obligations referred to
therein, or as to the successful assertion of any equitable defense, inasmuch as
the availability of such remedies or the success of any such defenses may be
subject to the discretion of a court. We express no opinion as to the
enforceability of any indemnity provision that indemnifies any person against


                                      -E-2-

<PAGE>   118



damages arising from its own negligence or misconduct. We express no opinion as
to the enforceability of any covenant or agreement not to compete made or
executed in connection with the transactions contemplated by the Buyer's
Documents.

     Any reference to "our knowledge," or "knowledge," or references to matters
that are "known to us," "of which we are aware" or that have "come to our
attention" or any variation of any of the foregoing shall mean the conscious
awareness of the attorneys in this firm who have rendered substantive attention
to the transactions contemplated by the Buyer's Documents of the existence or
absence of any facts which would contradict our opinions set forth below. We
have not undertaken, for purposes of this opinion, any independent investigation
to determine the existence or absence of such facts, and no inference as to our
knowledge of the existence or absence of such facts should be drawn from the
fact of our representation of the Buyer. Without limiting the foregoing, for
purposes of our opinions below, we have not searched any computerized or
electronic databases, nor have we conducted a search of the dockets of any court
or administrative or other regulatory agency or other filing office in any
jurisdiction.

     Our opinion expressed in paragraph 1 below as to the valid existence and
good standing of the Buyer as a corporation incorporated in the jurisdiction
referred to therein, is based solely upon the certificate referred to in clause
(b) above, a copy of which has been furnished to you, and our opinion is limited
accordingly and rendered as of the date of such certificate. We express no
opinion as to the tax good standing of the Buyer.

     We express no opinion herein as to the laws of any state or jurisdiction
other than state laws of The Commonwealth of Massachusetts and the federal laws
of the United States of America. To the extent that the laws of any other
jurisdiction govern the agreements or transactions as to which we are opining
herein, we have assumed, with your permission, that such laws are identical to
those of the state laws of The Commonwealth of Massachusetts, and we express no
opinion herein as to whether such assumption is reasonable or correct.

     For purposes of our opinions rendered below, we have assumed that the facts
and law governing the future performance by the Buyer of its obligations under
the Buyer's Documents will be identical to the facts and law governing its
performance on the date of this opinion.

     On the basis of and subject to the foregoing, we are of the opinion that:

     1.   The Buyer is a corporation validly existing and in corporate good
          standing under the laws of The Commonwealth of Massachusetts and has
          all requisite corporate power and authority to execute and deliver

          the Buyer's Documents, and to consummate the transactions contemplated
          thereby.

     2.   The Shares of the Buyer's Common Stock when issued in accordance with
          the terms of the Stock Purchase Agreement will have been validly
          issued, fully paid and nonassessable.

     3.   The execution and delivery by the Buyer of the Buyer's Documents, and
          the performance by the Buyer of its obligations thereunder, have been
          duly authorized by all requisite corporate action on the part of the
          Buyer.

     4.   The Buyer's Documents have been duly executed and delivered by the
          Buyer and constitute the valid and binding obligations of the Buyer,
          enforceable against it in accordance with their respective terms.

     5.   The execution and delivery of the Buyer's Documents by the Buyer, and
          the performance by the Buyer of its obligations thereunder do not, and
          will not, conflict with or result in any breach of the terms,
          conditions or provisions of, or constitute a default under, the
          Articles of Organization or Bylaws of the Buyer.

     This opinion is provided to you as a legal opinion only and not as a
guaranty or warranty of the matters discussed herein. This opinion is based upon
currently existing statutes, rules, regulations and judicial decisions, and we
disclaim any obligation to advise you of any change in any of these sources of
law or subsequent legal or factual developments which might affect any matters
or opinions set forth herein.

     Please note that we are opining only as to the matters expressly set forth
herein, and no opinion should be inferred as to any other matters. This opinion
is solely for your benefit in connection with the consummation of the
transactions contemplated by the Agreement, and may not be quoted or relied upon
by any other person or used for any other purpose, without our prior written
consent. John K.P. Stone, III, partner in this Firm, is the Assistant Clerk of
the Buyer.


                                         Very truly yours,
