                                 DONJOY, L.L.C.
                                1999 OPTION PLAN

      1.    PURPOSE OF THE PLAN

            The purpose of the Second Amended and Restated DonJoy, L.L.C. 1999
Option Plan (the "Plan") is (i) to 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 Company and/or its Subsidiaries. For purposes of the Plan,
the term "Subsidiary" shall mean "Subsidiary Corporation" as defined in Section
424(f) of the Internal 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.

exercised, new Options may be granted under clauses (i) through (iv) above with
respect to the Units covered by the unexercised portion of such terminated,
expired or canceled Options.

            (b)   Character of Units

            The Units issuable upon exercise of an Option granted under the Plan

            Options may be granted under the Plan at any time and from time to
time on or prior to the tenth anniversary of the Effective Date (as defined in

plenary authority, in its discretion, to determine:

                  (i)   the persons (from among the class of persons eligible to
      receive Options under the Plan) whom Options shall be granted (the
      "Optionees");

                  (ii)  the time or times at which Options shall be granted;

agreement (an "Option Agreement"), containing such terms and conditions and in
such form, not inconsistent with the Plan, as the Committee shall, in its
discretion, provide. Each Option Agreement shall be executed by the Company and
the Optionee.

            (c)   No Evidence of Employment or Service

            Nothing contained in the Plan or in any Option Agreement shall
confer upon any Optionee any right with respect to the continuation of his or
her employment by or service with the Company or any of its Subsidiaries or
interfere in any way with the right of the Company or any such Subsidiary
(subject to the terms of any separate agreement to the contrary) at any time to

Option.

            (d)   Date of Grant

            The date of grant of an Option under the Plan shall be the date as

employee of the Company or one of its Subsidiaries.


                                       3
<PAGE>   4

      6.    OPTION PRICE

            Subject to Section 9, the price (the "Option Price") at which each
Unit subject to an Option granted under the Plan may be purchased shall be
determined by the Committee at the time the Option is granted.

      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
forth in the Option Agreement evidencing such Option. If an Option is not at the
time of grant immediately exercisable, the Committee may (i) in the Option
Agreement evidencing such Option, provide for the acceleration of the exercise
date or dates of the subject Option upon the occurrence of specified events
and/or (ii) at any time prior to the complete termination of an Option,
accelerate the exercise date or dates of such Option.

            (b)   Automatic Termination of Options

            The unexercised portion of any Option granted under the Plan shall
automatically terminate and shall become null and void and be of no further
force or effect upon the first to occur of the following:

                  (i)   the end of the stated term thereof;

                  (ii)  if the Optionee is an employee, unless a shorter period
      is provided for in any Option Agreement, the expiration of three months
      from the date that the Optionee ceases to be an employee of the Company or
      any of its Subsidiaries (other than as a result of an Involuntary
      Termination (as defined in clause (iii) below) or termination For Cause
      (as defined herein)); provided, however, that if the Optionee shall die
      during such three-month period, the time of termination of the unexercised
      portion 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 any of its Subsidiaries, if such termination is due to such
      Optionee's death or Disability (as defined below) (an "Involuntary
      Termination");

                  (iv)  if the Optionee is an employee, immediately upon the
      date that the Optionee ceases to be an employee of the Company or any of
      its Subsidiaries, if such termination is For Cause;

                  (v)   the expiration of such period of time or the occurrence
      of such event as the Committee in its discretion may provide in the Option
      Agreement;


                                       4
<PAGE>   5

                  (vi)  on the effective date of a Material Transaction (as
      defined 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
      distribution), assigned, pledged, hypothecated, attached or otherwise
      disposed of by the Optionee.

            As used herein, "Disability" means any accident, sickness,
incapacity or other disability which (i) renders the Optionee unable to
substantially perform all of his duties for 90 days during any period of 360
consecutive days or (ii) would reasonably be expected to render the Optionee
unable to substantially 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.

            As used herein, "For Cause" shall mean (i) the failure by the
Optionee to perform such duties as are reasonably requested by the Board or the
Chief Executive Officer of the Company or its Subsidiaries, as applicable, (ii)
the Optionee's failure to observe any material policies of the Company or its
Subsidiaries, as applicable, (iii) gross negligence or willful misconduct by the
Optionee in the performance of his duties, (iv) the commission by the Optionee
of any act of fraud, theft or financial dishonesty with respect to the Company
or any of its Affiliates, or any felony or act involving moral turpitude, (v)
the material breach by the Optionee of his/her employment agreement (if
applicable) with the Company or its Subsidiaries, as applicable, or of any other
agreement or contract with the Company or any Affiliate thereof (including,
without limitation, the Members' Agreement of the Company or any option
agreement which must be entered into pursuant to this Plan), (vi) chronic
absenteeism or (vii) the failure of the Optionee to give at least 30 days' prior
written notice of his termination of employment with the Company or its
Subsidiaries, as applicable. For purposes of this Agreement, "Affiliates" means
dj Orthopedics, LLC (or its successors or assigns) and all subsidiaries thereof.

            Anything contained in the Plan to the contrary notwithstanding,
unless otherwise provided in an Option Agreement, no Option granted under the
Plan shall be affected by any change of duties or position of the Optionee
(including a transfer to or from the Company or one of its Subsidiaries), so
long as such 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
<PAGE>   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
<PAGE>   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
<PAGE>   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.


                                       8

      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
<PAGE>   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
