                           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 GREG KASEESKA
("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 Fifteen 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) $15 shall be paid by cashor 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 shall
            -------
inure to the benefit of the successors, assigns, legal representatives, heirs,
legatees, executors and administrators of the respective parties hereto.

     8.     Modifications. This Agreement may be altered or amended,
            -------------
in whole or in part at any time only by written instrument signed by
the Company and Employee setting forth such changes.

            -----------------
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.

            ------------
hereof be determined to be illegal or unenforceable, all of the other
provisions hereof shall be given effect separately therefrom and
shall not be affected thereby.

             (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 to
time provided that at least ten days notice of the continuation of such sale
is given to Debtor.  Upon any sale, Secured Party may bid for and purchase
the Collateral, or any part thereof, and upon compliance with the terms of
sale may hold, retain, possess and dispose of the Collateral, in its absolute
right without further accountability. Secured Party shall have the right to
be credited on the amount of its bid a corresponding amount of the Secured
Obligations as of the date of such sale.

     Section 4.3     Application of Proceeds. Except as otherwise required
                     -----------------------
by applicable law, Secured Party may apply the proceeds of any foreclosure
sale hereunder as follows:

             (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
priority as Secured Party may determine in its discretion; and

             (e)     the remainder of such proceeds, if any, shall be paid
to the record owner of the Collateral.

     Section 4.4     Enforcement of Secured Obligation. Nothing in this
                     ---------------------------------
Agreement or in any other agreement shall affect or impair the unconditional
and absolute right of the Secured Party to enforce the Secured Obligations as
and when the same shall become due in accordance with the terms of the Note
or other documents evidencing the Secured Obligations.

                             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.

                     ---------
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.
