further the growth and success of, DonJoy, L.L.C. (the "Company") and its
Subsidiaries (as hereinafter defined) by enabling directors and employees of,
and independent consultants and contractors to, the Company and any of its
Subsidiaries to acquire equity ownership interests in the Company (the "Units"),
thereby increasing their personal interest in such growth and success, and (ii)
to provide a means of rewarding outstanding performance by such persons to the

Revenue Code of 1986, as amended.

   2. ADMINISTRATION OF THE PLAN

       (a) Option Committee

       The Plan shall be administered by the Board of Managers of the Company
(the "Board") or a three-person Option Committee (the "Committee") appointed
from time to time by the Board. Any reference in the Plan to action by the
Company means action by or under the authority of the Board or the Committee.
The members of the Committee may be removed by the Board at any time either with
or without cause. Any vacancy on the Committee, whether due to action of the
Board or any other cause, shall be filled by the Board. The term "Committee"
shall, for all purposes of the Plan other than this Section 2, be deemed to
refer to the Board if the Board is administering the Plan.

       (b) Procedures

       The Committee shall adopt such rules and regulations as it shall deem
appropriate concerning the holding of meetings and the administration of the
Plan. A majority of the entire Committee shall constitute a quorum and the
actions of a majority of the members of the Committee present at a meeting at
which a quorum is present, or actions approved in writing by all of the members
of the Committee, shall be the actions of the Committee.

       (c) Interpretation

       Except as otherwise expressly provided in the Plan, the Committee shall
have all powers with respect to the administration of the Plan, including,
without limitation, full power and authority to interpret the provisions of the
Plan and any Option Agreement (as defined in Section 5(b)), and to resolve all
questions arising under the Plan. All decisions of the Board or the Committee,
as the case may be, shall be conclusive and binding on all participants in the
Plan.

   7. EXERCISABILITY OF OPTIONS

       (a) Committee Determination

       Each Option granted under the Plan shall be exercisable at such time or
times, or upon the occurrence of such event or events, and for such number of
Units subject to the Option, as shall be determined by the Committee and set

and/or (ii) at any time prior to the complete termination of an Option,
accelerate the exercise date or dates of such Option.

   shall be the expiration of 12 months from the date that such Optionee ceased
   to be an employee of the Company or any of its Subsidiaries;

              (iii) if the Optionee is an employee, the expiration of 12 months
   from the date that the Optionee ceases to be an employee of the Company or

       in Section 9(b)(i)) to which Section 9(b)(ii) (relating to assumptions
       and substitutions of Options) does not apply; and

              (vii) except to the extent permitted by Section 9(b)(ii), the date
       on which an Option or any part thereof or right or privilege relating
       thereto is transferred (otherwise than by will or the laws of descent and

perform all of his duties for 90 days during any period of 360 consecutive days,
in the case of each of clauses (i) or (ii), as determined by the Board
(excluding the Optionee should he be a member of the Board at the time of such
determination) in its good faith judgment.

Optionee continues to be an employee of the Company or one of its Subsidiaries.

   8. PROCEDURE FOR EXERCISE

       (a) Payment

       Payment upon exercise of an Option shall be made, at the election of the
Optionee, (i) in cash or personal or certified check payable to the Company in
an amount equal to the aggregate Option Price of the Units with respect to which
the Option is being exercised or (ii) upon the surrender of Units or option to
buy Units, in each case with such Units or Options to


                                        5
   6

buy Units, as the case may be, valued at the Fair Value per Unit (as defined in
Section 8) thereof as determined by the Committee.

       (b) Notice

       An Optionee (or other person, as provided in Section 10(b)) may exercise
an Option granted under the Plan in whole or in part (but for the purchase of
whole Units only), as provided in the Option Agreement evidencing his Option, by
delivering a written notice (the "Notice") to the Secretary of the Company. The
Notice shall state:

              (i) that the Optionee elects to exercise the Option;

              (ii) the number of Units with respect to which the Option is being
       exercised (the "Optioned Units");

              (iii) the method of payment for the Optioned Units (which method
       must be available to the Optionee under the terms of his or her Option
       Agreement);

              (iv) the date upon which the Optionee desires to consummate the
       purchase (which date must be prior so the termination of such Option);

              (v) a copy of any election filed by the Optionee pursuant to
       Section 83(b) of the Code; and

              (vi) such further provisions consistent with the Plan as the
       Committee may from time to time require.

       The exercise date of an Option shall be the date on which the Company
receives the Notice from the Optionee.

       (c) Issuance of Certificates

       The Company shall issue a certificate in the name of the Optionee (or
such other person exercising the Option in accordance with the provisions of
Section 10(b)) for the Optioned Units as soon as practicable after receipt of
the Notice and payment of the aggregate Option Price for such Units. Neither the
Optionee nor any person exercising an Option in accordance with the provisions
of Section 10(b) shall have any privileges as a holder of Units with respect to
any Units subject to an Option granted under the Plan until the date of payment
for such Units pursuant to the Option.

       (d) Determination of Fair Market Value.

       Fair Market Value of each Unit shall be determined in accordance with the
following:

              (i) "FAIR VALUE PER UNIT " shall mean, as of any date of
       determination, the fair value of each Unit (or, with respect to a warrant
       or option, the fair value of each Unit obtainable upon exercise thereof
       net of the exercise price), determined as follows:


                                        6
   7

       At any time that the Fair Value Per Unit shall be required to be
       determined hereunder, the Board shall make a good faith determination
       (the "Board's Determination") of the fair value of each Unit within 30
       days of the delivery by the Company of a Repurchase Notice (as defined in
       the Operating Agreement) (without taking into account that the Units may
       be "restricted securities" but with a reasonable discount, for the
       minority position represented by the Units and shall provide to the
       Member (as defined in the Operating Agreement) with respect to whose Unit
       such determination is being made a written notice thereof which notice
       shall set forth supporting data in respect of such calculation (the
       "Determination Notice"). The Member shall have 10 days following receipt
       of the Determination Notice within which to deliver to the Company a
       written notice (the "Objection Notice") of an objection, if any, to the
       Board's Determination, which Objection Notice shall set forth the
       Member's good faith determination (the "Member's Determination") of the
       fair value of each Unit. The failure by the Member to deliver the
       Objection Notice within such 10-day period shall constitute the Member's
       acceptance of the Board's Determination as conclusive. In the event of
       the timely delivery of an Objection Notice, the Company and the Member
       shall attempt in good faith to arrive at an agreement with respect to the
       Fair Value per Unit, which agreement shall be set forth in writing within
       15 days following delivery of the Objection Notice. If the Company and
       the Member are unable to reach an agreement within such 15-day period,
       the matter shall be promptly referred for determination to a regionally
       or nationally recognized investment banking or valuation firm (the
       "Valuer") reasonably acceptable to the Company and the Member. The
       Company and the Member will cooperate with each other in good faith to
       select such Valuer. The Valuer may select the Board's Determination or
       the Member's Determination as the Fair Value Per Unit or may select any
       other number or value (determined without taking into account that the
       Units may be "restricted securities" but with a reasonable discount, not
       to exceed 20% for the minority position represented by the Units). The
       Valuer's selection will be furnished to the Company and the Member in
       writing and conclusive and binding upon the Company and the Member. The
       fees and expenses of the Valuer shall be borne equally by the Company and
       the Member with respect to whose Units such determination relates;
       provided, however, that if the Fair Value per Unit, as determined by the
       Valuer, shall be more than 15% greater than the Board's Determination of
       such Fair Value per Unit, then such fees and expenses of the Valuer
       shall be borne entirely by the Company.

   9. ADJUSTMENTS

       (a) Changes in Capital Structure

       Subject to Section 9(b), if the Unit is changed by reason of a split,
reverse split or recapitalization, or converted into or exchanged for other
securities as a result of a merger, consolidation or reorganization, the
Committee shall make such adjustments in the number and class of Units with
respect to which Options may be granted under the Plan as shall be equitable and
appropriate in order to make such Options, as nearly as may be practicable,
equivalent to such Options immediately prior to such change. A corresponding
adjustment changing the


                                        7
   8

number and class of Units allocated to, and the Option Price of, each Option or
portion thereof outstanding at the time of such change shall likewise be made.

       (b) Material Transactions

       The following rules shall apply in connection with the dissolution or
liquidation of the Company, a reorganization, merger or consolidation in which
the Company is not the surviving corporation, or a sale of all or substantially
all of the assets of the Company to another person or entity (each, a "Material
Transaction"), unless otherwise provided in the Option Agreement or in the
Members' Agreement of even date herewith:

              (i) each holder of an Option outstanding at such time shall be
       given (A) written notice of such Material Transaction at least 20 days
       prior to its proposed effective date (as specified in such notice) and
       (B) an opportunity, during the period commencing with delivery of such
       notice and ending 10 days prior to such proposed effective date, to
       exercise the Option to the full extent to which such Option would have
       been exercisable by the Optionee at the expiration of such 20-day period;
       provided, however, that upon the occurrence of a Material Transaction,
       all Options granted under the Plan and not so exercised shall
       automatically terminate; and

              (ii) Notwithstanding anything contained in the Plan to the
       contrary, Section 9(b)(i) shall not be applicable if provision shall be
       made in connection with such Material Transaction for the assumption of
       outstanding Options by, or the substitution for such Options of new
       options covering the equity securities of, the surviving, successor or
       purchasing corporation, or a parent or subsidiary thereof, with
       appropriate adjustments as to the number, kind and option prices of Units
       subject to such options.

          (c) Special Rules

             The following rules shall apply in connection with Section 9(a) and
(b) above:

              (i) no fractional Units shall be issued as a result of any such
       adjustment, and any fractional Units resulting from the computations
       pursuant to Section 9(a) or (b) shall be eliminated and the Optionee
       shall receive cash consideration for such fractional Unit at the rate of
       the Fair Market Value of such Unit, determined in accordance with clause
       (d) below;

              (ii) no adjustment shall be made for cash dividends or the
       issuance to holders of rights to subscribe for additional Units or other
       securities; and

              (iii) any adjustments referred to in Section 9(a) or (b) shall be
       made by the Board or Committee (as the case may be) in good faith and
       shall be conclusive and binding on all persons holding Options granted
       under the Plan.

  10. RESTRICTIONS ON OPTIONS AND OPTIONED UNITS

       (a) Compliance With Securities Laws

       No Options shall be granted under the Plan, and no Units shall be issued
and delivered upon the exercise of Options granted under the Plan, unless and
until the Company and/or the Optionee shall have complied with all applicable
Federal or state registration, listing and/or qualification requirements and all
other requirements of law or of any regulatory agencies having jurisdiction.

       The Committee in its discretion may, as a condition to the exercise of
any Option granted under the Plan, require an Optionee (i) to represent in
writing that the Units received upon exercise of an Option are being acquired
for investment and not with a view to distribution and (ii) to make such other
representations and warranties as are deemed appropriate by the Company.
Certificates representing Units acquired upon the exercise of Options that have
not been registered under the Securities Act shall, if required by the
Committee, bear the following legend and such additional legends as may be
required by the Option Agreement evidencing a particular Option:

            "THE UNITS REPRESENTED BY THIS CERTIFICATE HAVE NOT BEEN
            REGISTERED UNDER THE SECURITIES ACT OF 1933, AS AMENDED
            (THE "SECURITIES ACT"). THE UNITS HAVE BEEN ACQUIRED FOR
            INVESTMENT AND MAY NOT BE PLEDGED, HYPOTHECATED, SOLD OR
            TRANSFERRED IN THE ABSENCE OF AN EFFECTIVE REGISTRATION
            STATEMENT FOR THE UNITS UNDER THE SECURITIES ACT OR AN
            OPINION OF COUNSEL TO THE COMPANY THAT REGISTRATION IS NOT
            REQUIRED UNDER SAID ACT."

       (b) Nonassignability of Option Rights

       No Option granted under the Plan shall be assignable or otherwise
transferable by the Optionee except by will or by the laws of descent and
distribution. An Option may be exercised during the lifetime of the Optionee
only by the Optionee. If an Optionee dies, his or her Option shall thereafter be
exercisable, during the period specified in Section 7(b)(ii) or (iii) (as the
case may be), by his or her executors or administrators to the full extent to
which such Option was exercisable by the Optionee at the time of his or her
death.

  11. EFFECTIVE DATE OF PLAN

       The Plan shall become effective on the date of its adoption by the Board.

  12. EXPIRATION AND TERMINATION OF THE PLAN

       Except with respect to Options then outstanding, the Plan shall expire on
the first to occur of (i) the fifteenth anniversary of the date on which the
Plan is approved by the holders of Units and (ii) the date as of which the
Board, in its sole discretion, determines that the Plan


                                        9
   10

shall terminate (the "Expiration Date"). Any Options outstanding as of the
Expiration Date shall remain in effect until they have been exercised or
terminated or have expired by their respective terms.

  13. AMENDMENT OF PLAN

       The Board may at any time prior to the Expiration Date modify and amend
the Plan in any respect. No such amendment to the Plan shall affect the terms or
provisions of any Option granted by the Company prior to the effectiveness of
such amendment.

  14. CAPTIONS

            The use of captions in the Plan is for convenience. The captions are
not intended to provide substantive rights.

  15. WITHHOLDING TAXES

       Whenever under the Plan, Units are to be delivered by an Optionee upon
exercise of an Option, the Company shall be entitled to require as a condition
of delivery that the Optionee remit or, in appropriate cases, agree to remit
when due, an amount sufficient to satisfy all current or estimated future
Federal, state and local income tax withholding the employee's portion of any
employment tax requirements relating thereto.

  16. OTHER PROVISIONS

       Each Option granted under the Plan may contain such other terms and
conditions not inconsistent with the Plan as may be determined by the Committee,
in its sole discretion.

  17. NUMBER AND GENDER

            With respect to words used in the Plan, the singular form shall
include the plural form, the masculine gender shall include the feminine gender,
and vice-versa, as the context requires

  18. GOVERNING LAW

       The validity and construction of the Plan and the instruments evidencing
the Options granted hereunder shall be governed by the laws of the State of
Delaware.
