         1.       PURPOSE OF THE PLAN

                  The purpose of the Fourth 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.

                  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

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

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.

                           (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

                  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>


                           (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)

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

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

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>


                  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

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
<Page>


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.
