                           RESTRICTED STOCK AGREEMENT

          THIS RESTRICTED STOCK AGREEMENT (this "Agreement") is entered into
effective as of this 12th day of June, 2001, by and between ENCORE MEDICAL
CORPORATION, a Delaware corporation (the "Company"), and HARRY L. ZIMMERMAN
("Employee").

         WHEREAS, Employee has agreed to terminate the Severance Agreement that
Employee has with the Company in return for the Company selling Employee shares
of the common stock, $0.001 par value per share (the "Common Stock"), of the
Company pursuant to the terms of this Agreement;

         NOW, THEREFORE, for and in consideration of the premises and the
mutual covenants herein contained and other good and valuable consideration,
the receipt and sufficiency of which are hereby acknowledged, the parties
hereto, intending legally to be bound, agree as follows:

         1.       Grant of Restricted Shares.  The Company hereby agrees to
                  --------------------------
sell to Employee an aggregate of One Hundred Fifty Thousand (150,000) shares
(the "Restricted Shares") of Common Stock on the terms and conditions
hereinafter set forth.

         2.       Purchase  Price.  The purchase price of the Restricted
                  ---------------
Shares shall be One and 2/100 Dollars  ($1.02) per share (the "Purchase
Price")

         3.       Payment of Purchase  Price.  The Purchase  Price shall be
                  --------------------------
paid as follows:  (a) $150 shall be paid by cash or good check  simultaneous
with the execution of this  Agreement and (b) the remainder  shall be paid by
Employee delivering to Company a secured promissory note payable to the Company
in the form attached hereto as Exhibit A.

         4.       Delivery of Shares. Upon the payment of the Purchase Price by
                  ------------------
Employee or as soon thereafter as is practicable, the Company shall issue and
deliver to Employee a certificate or certificates evidencing the number of
Restricted Shares. Such certificate or certificates shall be registered in the
name of Employee and shall bear an appropriate investment warranty legend, any
legend required by any federal or state securities law, rule or regulation and,
if applicable, a legend referring to the restrictions provided hereunder. Upon
the issuance and delivery of such certificate or certificates, Employee shall
have all the rights of a stockholder with respect to such Restricted Shares and
to receive all dividends or other distributions paid or made with respect
thereto; provided, however that such Restricted Shares shall be subject to the
restrictions hereunder. Notwithstanding, such delivery, Company shall retain
possession of such certificates pursuant to the terms of the Security Agreement
attached hereto as Exhibit B.

         5.       Period of Restriction.
                  ---------------------

                  (a)     Subject to Paragraph 7, the Restricted Shares shall
constitute "Vested Shares" pro rata over a period of thirty-six (36) months,
beginning one month after the date of this Agreement. Notwithstanding the
foregoing schedule, the Company may deem all or any portion of the Restricted
Shares to be Vested Shares whenever, in the Company's sole discretion,
circumstances warrant such action.  Furthermore, should there be a "Change in
Control" of the Company as defined herein, then all remaining Restricted Shares
shall be deemed to be Vested Shares.

                  (b)     "Unvested Shares" shall mean Restricted Shares which
are not Vested Shares in accordance with subparagraph (a) above.
<PAGE>

                  (c)     Employee shall not sell, assign, transfer, pledge,
gift or otherwise dispose of any Unvested Shares, and no Unvested Shares shall
be transferred on the Company's books without the prior written consent of the
Company.

                  (d)     "Change in Control" shall mean a change in control of
a nature that is reportable in response to Item 6(e) of Schedule 14A of
Regulation 14A promulgated under the Securities Exchange Act of 1934 (the
"Exchange Act") as in effect on the date hereof; provided that, without
limitation, such a change in control shall be deemed to have occurred if any
"person" (as such term is used in Sections 13(d) and 14(d)(2) of the Exchange
Act) is or becomes the beneficial owner, directly or indirectly, of securities
of the Company representing a majority or more of the combined voting power of
the Company's then outstanding securities.

                  (e)     In the event Employee shall voluntarily leave the
employment of the Company or be terminated for cause, then Employee shall be
required, effective as of the last day of employment, to sell any remaining
Restricted Shares to the Company at a price per share equal to the Purchase
Price. Termination for cause shall mean a discharge resulting from Employee
having (i) failed or refused to follow legal and reasonable policies or
directives established and previously given to Employee in writing by Company,
(ii) willfully failed to attend to his duties after ten (10) days prior written
notice of failure to so act, (iii) committed acts amounting to gross negligence
or willful misconduct to the material detriment of Company, or (iv) otherwise
materially breached any of the terms or provisions of any employment agreement
that the Employee has with the Company after ten (10) days prior written notice
of such material breach and failure to cure such breach. Employee shall be
deemed to have been terminated for cause upon delivery to Employee of a "Notice
of Termination" stating the "Date of Termination" and specifying the
particulars of the conduct justifying discharge for cause.

         6.       Shares Not Transferable. As a condition to the issuance of
                  -----------------------
Restricted Shares, the Company may require an opinion of counsel and/or a
representation letter from the purchaser(s) of such shares, satisfactory to the
Company, to the effect that such transfer will not be in violation of the
Securities Act of 1933, as amended (the "Securities Act"), or any other
applicable securities laws or that such transfer has been registered under the
Securities Act and the Company shall not be liable for damages due to delay in
the delivery or issuance of any stock certificates representing Restricted
Shares purchased hereunder for any reason whatsoever, including, but not
limited to, a delay caused by listing requirements of any securities exchange
or any registration requirements under the Securities Act, the Securities
Exchange Act of 1934, as amended, or under any other state or federal law, rule
or regulation. The Company is under no obligation to take any action or to
incur any expense to register or qualify the delivery or transfer Restricted
Shares under applicable securities laws or to perfect any exemption from such
registration or qualification. Furthermore, the Company will have no liability
to Employee for refusing to deliver or transfer Restricted Shares purchased
hereunder if such refusal is based upon the foregoing provisions of this
Paragraph 6.

         7.       Benefit.  This  Agreement  shall  be  binding  upon and
                  -------

representatives, heirs, legatees, executors and administrators of the
respective parties hereto.

                  -------------
amended,  in whole  or in part at any  time  only by written instrument signed
by the Company and Employee setting forth such changes.

         9.       Entire  Agreement.  This Agreement  contains the entire
                  -----------------
agreement between the parties with respect to the subject matter described
herein, and no waiver of any of the terms of this Agreement shall be valid
unless signed by the party against whom such waiver is asserted.

provisions hereof shall be given effect separately therefrom and shall not be
affected thereby.

                  granted.

                  (c)    Secured Party may foreclose this Agreement in the
manner now or hereafter provided or permitted by law and shall have the
immediate right to receivership pending foreclosure, and may upon such
reasonable notification prior thereto as may be required by applicable law
(Debtor hereby agreeing that 10 days notice is commercially reasonable), sell,
assign, transfer or otherwise dispose of the Collateral at public or private
sale, in whole or in part, and Secured Party may, in its own name or as the
irrevocably appointed attorney-in-fact of Debtor effectively assign and
transfer the Collateral, or any part thereof, absolutely, and execute and
deliver all necessary assignments, conveyances, bills of sale and other
instruments with power to substitute one or more persons or corporations with
like power. Any such foreclosure sale, assignment, or transfer shall, to the
extent permitted by law, be a perpetual bar, both at law and in equity, against
Debtor and all persons and corporations lawfully claiming by or through or
under Debtor.

                  (d)    Any such foreclosure sale may be adjourned from time

credited on the amount of its bid a corresponding amount of the Secured
Obligations as of the date of such sale.

                         -----------------------
by applicable law, Secured Party may apply the proceeds of any foreclosure sale

                  (a)    first, to the payment of all costs and expenses of
any  foreclosure and collection  hereunder and all proceedings in connection
therewith, including reasonable attorneys' fees;

                  (b)    then, to the reimbursement of Secured Party for all
disbursements made by Secured Party for taxes, assessments or liens superior to
the security interest hereof and which Secured Party shall deem expedient to
pay in order to protect its interest in the Collateral;

                  (c)    then,  to the  reimbursement  of  Secured  Party of
any other  disbursements  made by Secured Party in accordance with the terms
hereof;

                  (d)    then, to or among the amounts of fees and principal
then outstanding and unpaid in respect of the Secured Obligations, in such

                             RIGHTS OF SECURED PARTY

         Section 5.1     Subrogation. Upon the occurrence of an Event of
                         -----------
Default, Secured Party, at its election, may subrogate to all of the interest,
rights and remedies of Debtor, in respect to any of the Collateral or
agreements pertaining thereto.

         Section 5.2     Secured Party Appointed Attorney-in-Fact. Debtor
                         ----------------------------------------
hereby irrevocably appoints Secured Party as attorney-in-fact of Debtor, with
full authority in the place and stead of Debtor and in the name of Debtor,
Secured Party or otherwise, from time to time on Secured Party's discretion and
upon the occurrence of an Event of Default, to take any action and to execute
any instrument which Secured Party may deem necessary or advisable to
accomplish the purposes of this Agreement, including without limitation: (a) to
ask, demand, collect, sue for, recover, compound, receive and give acquittance
and receipts for moneys due and to become due under or in respect of any of the
Collateral; and (b) to assign and transfer the Collateral, or any part thereof,
absolutely and to execute and deliver endorsements, assignments, conveyances,
bills of sale and other instruments with power to substitute one or more
persons or corporation with like power.

         Section 5.3     Performance by Secured Party. If Debtor fails to
                         ----------------------------
perform any agreement contained herein, Secured Party may itself perform, or
cause the performance of, such agreement, and the reasonable expenses of
Secured Party incurred in connection therewith shall be payable by Debtor under
Section 5.8.  In no event, however, shall Secured Party have any obligation or
duties whatsoever to perform any covenant or agreement of Debtor contained
herein, and any such performance by Secured party shall be wholly discretionary
with Secured Party.

         Section 5.4     Duties of Secured Party. The powers conferred upon
                         -----------------------
Secured Party hereunder are solely to protect its interest in the Collateral
and shall not impose any duty upon it to exercise any such powers. Except for
the safe custody of any Collateral in its possession and the accounting for
money actually received by it hereunder, Secured Party shall have no duty as to
any Collateral or as to the taking of any necessary steps to preserve rights
against prior parties or any other rights pertaining to any Collateral.

         Section 5.5     No Liability of Secured Party. Neither the acceptance
                         -----------------------------
of this Agreement by Secured Party, nor the exercise of any rights hereunder by
Secured Party, shall be construed in any way as an assumption by Secured Party
of any obligations, responsibilities or duties of Debtor arising in connection
with the Collateral assigned hereunder or otherwise bind Secured Party to the
performance of any obligations respecting the Collateral, it being expressly
understood that Secured Party shall not be obligated to perform, observe or
discharge any obligation, responsibility, duty, or liability of Debtor in
respect of any of the Collateral, including, but not limited to, appearing in
or defending any action, expending any money or incurring any expense in
connection therewith.

         Section 5.6     Right of Secured Party to Defend Action Affecting
                         -------------------------------------------------
Security. Secured Party may, at the expense of Debtor, appear in and defend any
--------
action or proceeding at law or in equity purporting to affect Secured Party's
security interest under this Agreement.

         Section 5.7     Right of Secured Party to Prevent or Remedy Default.
                         ---------------------------------------------------
If Debtor shall fail to perform any of the covenants, conditions and agreements
required to be performed and observed by Debtor in respect of the Collateral,
Secured Party (a) may but shall not be obligated to take any action Secured
Party deems necessary or desirable to prevent or remedy any such default by
Debtor or otherwise to protect the security interest of Secured Party under
this Agreement, and (b) shall have the absolute and

                                     -10-
<PAGE>

immediate right to take possession of the Collateral or any part thereof (to
the extent Secured Party has not previously taken possession) to such extent
and as often as the Secured Party, in its sole discretion, deems necessary or
desirable in order to prevent or to cure any such default by Debtor, or
otherwise to protect the security of this Agreement.  Secured Party may advance
or expend such sums of money for the account of Debtor as Secured Party in its
sole discretion deems necessary for any such purpose.

         Section 5.8     Secured Party's Expenses. All reasonable advances,
                         ------------------------
costs, expenses, charges and attorneys' fees which Secured Party may make, pay
or incur under any provision of this Agreement for the protection of its
security or for the enforcement of any of its rights hereunder, or in
foreclosure proceedings commenced and subsequently abandoned, or in any dispute
or litigation in which Secured Party or the holder of any of the Secured
Obligations may become involved by reason of or arising out of the Note or
other Secured Obligations or the Collateral shall be a part of the Secured
Obligations and shall bear interest until paid at the rate chargeable on the
Note but not to exceed the maximum rate of interest permitted by applicable
law, from the date of such payment until repaid by Debtor.

         Section 5.9     No Waiver. In case Secured Party shall have proceeded
                         ---------
to enforce any right or remedy hereunder and such proceedings shall have been
discontinued or abandoned for any reason, then in every such case, Debtor and
Secured Party shall be restored to their former positions and rights hereunder
with respect to the Collateral, and all rights, remedies and powers of Secured
Party shall continue as if no such proceeding had been taken. No failure or
delay on the part of Secured Party in exercising any right, remedy or power
under this Agreement or in giving or insisting upon strict performance by
Debtor hereunder or in giving notice hereunder shall operate as a waiver of the
same or any other power or right, and no single or partial exercise of any such
power or right shall preclude any other or further exercise thereof or the
exercise of any other such power or right. Secured Party, notwithstanding any
such failure, shall have the right thereafter to insist upon the strict
performance by Debtor of any and all of the terms and provisions of this
Agreement to be performed by the Debtor. The collection and application of
proceeds, the entering and taking possession of the Collateral, and the
exercise of the rights of Secured Party contained in this Agreement, shall not
cure or waive any default, or affect any notice of default, or invalidate any
acts done pursuant to such notice. No waiver by Secured Party of any breach or
default of or by any party hereunder shall be deemed to alter or affect Secured
Party's rights hereunder with respect to any prior or subsequent default.

         Section 5.10    Remedies. No right or remedy herein reserved to
                         --------
Secured Party is intended to be exclusive of any other right or remedy, but
each and every such remedy shall be cumulative, not in lieu of, but in addition
to any other rights or remedies given under this Agreement and all other
security documents. Any and all of Secured Party's rights and remedies may be
exercised from time to time and as often as such exercise as deemed necessary
or desirable by Secured Party.

         Section 5.11    Right of Secured Party to Extend Time of Payment,
                         -------------------------------------------------
Substitute, Release Security, Etc. Without affecting the liability of any
---------------------------------
person, including Debtor, for the payment of any of the Secured Obligations or
the lien of this Agreement on the Collateral, or the remainder thereof, for the
full amount of any indebtedness unpaid, Secured Party may from time to time,
without notice or without affecting or impairing any of Secured Party's rights
under this Agreement: (a) release any person liable for the payment of any of
such indebtedness, (b) extend the time or otherwise alter the terms of payment
of any of such indebtedness, (c) accept additional security therefor of any
kind, including deeds of trust or mortgages, (d) alter, substitute or release
any property securing the Secured Obligations, (e) resort for the payment of
all or any portion of the Secured Obligations to its several securities
therefor in such order and manner as it may deem fit, or (f) join in any
subordination or other agreement affecting this Agreement or the lien or charge
thereof.

         Section 5.12    Dividends. Upon the occurrence of an Event of
                         ---------
Default, Secured Party shall be entitled to any dividends, fees, receipts,
payments or other disbursements, attributable in any way to the Collateral.
Debtor shall take all actions necessary to cause the payor of such
disbursements to make such disbursements directly to Secured Party on account
of Debtor. Such amounts, when received by Debtor, will be applied to the
outstanding balance of the Note or the other Secured Obligations, as determined
by Secured Party. At all times during the term of this Agreement, Secured Party
will be entitled to all stock dividends and proceeds of the Collateral.

         Section 5.13    Delivery of Certificates. Simultaneously with the
                         ------------------------
execution of this Agreement, Debtor shall deliver to Secured Party all
certificates or other documentation evidencing the Collateral, along with such
endorsements or stock powers as the Secured Party may request. In the event
that Debtor receives any certificates evidencing the Collateral, Debtor shall
within three days of receipt, deliver such certificates to Secured Party along
with appropriate stock powers executed in blank.
