the promotion or commercialization of the Vista Technology as set forth in the

by virtue of ill health or other disability is unable to perform substantially
and continuously the duties assigned to him for more than 180 consecutive or
non-consecutive days out of any consecutive 12-month period, then the company
shall have the right, to the extent permitted by law, to terminate the
employment of Employee upon notice in writing to Employee. Upon termination of
employment due

incurred prior to the date of termination); and (ii) Employee (or, in the case
of his death, his estate and beneficiaries) shall have no further rights to any
other compensation or benefits hereunder on or after the termination of
employment, or any other rights hereunder, except as otherwise provided in the

                      c. Effect of Termination on Consulting Agreement. In the
event this Agreement is terminated under the terms of this Section 8, the
Consulting Agreement shall be null and void.

               9. Sole and Entire Agreement. This Agreement represents the sole
and entire agreement among the Parties and supersedes all prior agreements,
negotiations, and discussions between the Parties hereto and/or their respective
counsel, including without limitation any employment agreement, written or oral,
between the parties with respect to any subject matter, including, without
limitation, that certain Retention Agreement dated as of December 14, 1998,
except that this Agreement shall not supersede any agreement concerning
Employee's obligations to maintain as confidential any information of the
Company, nor shall it supersede the Consulting Agreement dated as of October 25,
1999, or any stock option agreement between the parties, except as expressly
modified herein. Employee hereby reaffirms his obligation to maintain in
confidence, and not to use for his or any other persons benefit, any
confidential trade secret information of the Company, including without
limitation, any business or marketing plan, financial information, customer
lists or information, supplier or manufacturer arrangements, and personnel
information. Any amendment to this


                                       5
<PAGE>   6

Agreement must be in writing, signed by duly authorized representatives of the
Parties, and stating the intent of the Parties to amend this Agreement.

               10. Representation by Counsel. Because both Parties have had an
opportunity to be represented by counsel and this Agreement was negotiated at
arms length, the usual presumption that an agreement to be interpreted against
the drafter shall not apply. The Parties further represent that they have no
question with regard to the legal import of any term, word, phrase, or portion
of this Agreement, or this Agreement in its entirety, and accept this Agreement
as written.

               11. Counterparts. This Agreement may be executed in counterparts,
each of which shall be deemed a complete original.

               12. Proper Authorization. Any person signing this Agreement on
behalf of another person, entity, association, or corporation represents and
warrants that such person has full power and authority to do so and to bind the
person, entity, association or corporation on whose behalf this Agreement is
executed.

               13. No Reliance. The Parties understand and agree that they have
each had an opportunity to investigate the matters being resolved hereunder, and
that each party is assuming the risk that any factual or legal matter upon which
they have relied may be incorrect, and that their misunderstanding, or
misinterpretation of any factual or legal matter shall not be a basis for
setting aside this Agreement.

               14. Governing Law. This Agreement will be governed by, and
construed in accordance with, the laws of the State of California, without
giving effect to conflicts of laws rules.

               15. Arbitration; Waiver of Jury Trial. Except for claims for
emergency equitable or injunctive relief which cannot be timely addressed
through arbitration, the parties hereby agree to submit any claim or dispute
arising out of the terms of this Agreement (including exhibits) and/or any
dispute arising out of or relating to


                                       6
<PAGE>   7

Consultant's consulting relationship with the Company in any way, to private and
confidential arbitration by a single neutral arbitrator through JAMS/Endispute.
Subject to the terms of this paragraph, the arbitration proceedings shall be
governed by the then current JAMS/Endispute rules governing employment disputes,
and shall take place in San Diego County, California. The decision of the
arbitrator shall be final and binding on all parties to this Agreement, and
judgment thereon may be entered in any court having jurisdiction. The Parties
shall share equally the arbitrator's fee and all costs of services provided by
the arbitrator and arbitration organization; however, all costs of the
arbitration proceeding or litigation to enforce this Agreement, including
attorneys' fees and witness expenses, shall be paid as the arbitrator or court
awards in accordance with applicable law. THE PARTIES ACKNOWLEDGE THAT THEY ARE
HEREBY WAIVING ANY RIGHT THEY MAY HAVE TO A JURY TRIAL OR ANY CLAIM SUBJECT TO
THIS SECTION 15. Except for claims for emergency equitable or injunctive relief
which cannot be timely addressed through arbitration, this arbitration procedure
is intended to be the exclusive method of resolving any claim relating to the
obligations set forth in this Agreement.

               WHEREOF, the Parties hereto have each executed this Agreement as
        of the date first above written.

hours with the Company's officers or employees with respect to such business
matters.

Company but is and shall be an independent contractor who, subject to the terms
hereof, shall have sole control of the manner and means of performing his
obligations under this Agreement. The Consultant shall not have, nor shall the
Consultant claim, suggest or imply that the Consultant has, any right, power or
authority to enter into any contract or obligation on behalf of, or binding
upon, the Company or any of its representatives. The Consultant may engage in
other activities as an employee of or consultant to other parties, which do not
prohibit or impair the performance of the Consultant's obligations under the

hours worked are to be submitted to the Chief Financial Officer of the Company,
or such other person as designated by the Chief Financial Officer of the Company
from time to time, on an invoice itemizing the hours worked each month and
services rendered. The Consultant shall also be reimbursed for any out-of-pocket
expenses incurred by him in performance of his duties hereunder, provided that
they are approved in advance in writing. Reimbursement for such expenses shall
be made within fifteen (15) days of Consultant's submission of receipts or other
appropriate evidence of the amount and nature of such expenses. The Consultant

Consultant shall not, either directly or indirectly, use (other than in the
performance of the Services) or disclose to any third person any Confidential
Information (as defined in subsection (b) below). The Consultant further agrees
not to make copies on any Confidential Information, except as may be expressly
authorized by the Company. All documents and material pertaining to the Company
or the Services made by the Consultant or that come into the possession of the
Consultant during the term of this Agreement are and shall remain the property
of the Company. Upon termination of this Agreement for any reason, or upon
earlier request of the Company, the consultant shall deliver to the Company all
such documents and materials in the Consultant's possession or control, in
addition to all forms of Confidential Information, and the Consultant shall not
allow a third party to take any of the foregoing.

               b. For the purposes of this Agreement, "Confidential Information"
shall mean any trade secrets or other information relating to the business of
the Company or its affiliates, or of any customer or supplier of the Company or

all other concepts or ideas related to the present or potential business of the
Company or its affiliates which the company is actively considering during the
Term of this Consulting Agreement.

               c. Consultant's obligations under this section 3 shall survive
the termination or expiration of this Agreement.

        4. Entire Agreement. The Agreement constitutes the whole agreement of
the parties in reference to any of the matters or things provided for in this
Agreement or discussed above and supersedes all prior agreements, promises,
representations and understandings. However, this agreement shall not modify or
supersede in any way the Employment and Separation Agreement entered into on

or any agreement restricting the use or disclosure of confidential trade secret
information, inventions or engaging in competition in any similar technology to

which the Consultant is providing services to the Company. Any provision of this
Agreement that is prohibited or unenforceable in any jurisdiction shall, as to
such jurisdiction, be ineffective to the extent of such prohibition or
enforceability without invalidating the remaining provisions of this Agreement,
and any such prohibition or unenforceability in any jurisdiction shall not
invalidate or render unenforceable such provision in any other jurisdiction.

        5. Choice of Law. This Agreement shall be governed by and construed and
enforced in accordance with the internal substantive laws (and not the laws of
conflicts) of the State of California.

        6. Amendment and Waiver. This Agreement may be amended, modified,
superseded, cancelled, renewed, extended or waived only by a written instrument
executed by the parties to this Agreement or, in the case of a waiver by the
party waiving compliance. No waiver by any party of the breach of any term or
provision contained in this Agreement, whether by conduct or otherwise, in any
one or more instances shall be deemed to be, or construed as, a further or
continuing waiver of any such breach, or a waiver of the breach of any other
term or covenant contained in this agreement.

        7. Notices. All notices, requests or consent required or permitted under
this Agreement shall be in writing and shall be given to the other party by

right under this Agreement, the prevailing party shall be entitled to recover
reasonable fees (including attorneys' fees), costs and other expenses incurred
in connection therewith, including the fees, costs and expenses of appeals.

inserted for convenience and reference only and do not constitute a part of this
Agreement.

        10. Arbitration; Waiver of Jury Trial. Except for claims for emergency
equitable or injunctive relief which cannot be timely addressed through
arbitration, the parties hereby agree to submit any claim or dispute arising out
of the terms of this Agreement (including exhibits) and/or any dispute arising
out of or relating to Consultant's consulting relationship with the Company in
any way, to private and confidential arbitration by a single neutral arbitrator

proceedings shall be governed by the then current JAMS/Endispute rules governing
employment disputes, and shall take place in San Diego County, California. The
decision of the arbitrator shall be final and binding on all parties to this
Agreement, and judgment thereon may be entered in any court having jurisdiction.
The Parties shall share equally the arbitrator's fee and all costs of services
provided by the arbitrator and arbitration organization; however, all costs of
the arbitration proceeding or litigation to enforce this Agreement, including
attorneys' fees and witness expenses, shall be paid as the arbitrator or court
awards in accordance with applicable law. THE PARTIES ACKNOWLEDGE THAT THEY ARE
HEREBY WAIVING ANY RIGHT THEY MAY HAVE TO A JURY TRIAL OR ANY CLAIM SUBJECT TO

                      (v) state the date upon which the Optionee desires to
consummate the purchase of such Vested Units (which date must be prior to the
termination of the Option); and

                      (vi) comply with such further provisions consistent with
the Plan as the Committee may reasonably require.

               (b) Payment of the Option Price for the Vested Units to be
purchased on the exercise of the Option shall be tendered with the Exercise
Notice, 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 buy Units, as the case may be, valued at the Fair Value per Unit
thereof as determined by the Committee administering the Plan and as otherwise
provided in Section 8 of the Plan.

               (c) The Company shall be entitled to require as a condition of

        Section 8. ADDITIONAL PROVISIONS RELATED TO EXERCISE.

               In the event of the exercise of the Option at a time when there
is not in effect a registration statement under the Securities Act of 1933, as
amended, relating to the Option, the Optionee hereby represents and warrants,
and by virtue of such exercise shall be deemed to represent and warrant, to the
Company that the Option and any Vested Units purchased hereunder are being

and the Optionee shall provide the Company with such further representations and
warranties as the Board may require in order to ensure compliance with
applicable federal and state securities, "blue sky" and other laws. No Vested
Units shall be purchased upon the exercise of the Option unless and until the
Company and/or the Optionee shall have complied with all applicable federal


                                       4
<PAGE>   16

or state registration, listing and/or qualification requirements and all other
requirements of law or of any regulatory agencies having jurisdiction. Each of
the Company and the Optionee shall use reasonable efforts to comply 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 in connection with the exercise of the Option.

        Section 9. RESTRICTION ON TRANSFER OF OPTIONS.

               The Option may not be Transferred by the Optionee and may be
exercised during the lifetime of the Optionee only by the Optionee. If the
Optionee dies, the Option shall thereafter be exercisable, during the period
specified in Section 7(b) of the Plan, by his executors or administrators to the
full extent to which the Option was exercisable by the Optionee at the time of
his death. The Option shall not be subject to execution, attachment or similar
process. Any attempted Transfer of the Option contrary to the provisions hereof,
and the levy of any execution, attachment or similar process upon the Option,
shall be null and void and without effect.

        Section 10. MEMBERS' AGREEMENT AND OPERATING AGREEMENT.

               The Optionee acknowledges that all Units purchased hereunder
shall be subject to the provisions of the Members' Agreement applicable to a
"Management Member" (as defined therein) and the Operating Agreement in addition
to the provisions of this Agreement and the Plan. The Optionee shall, as a
condition to the issuance of any Option Unit, execute a joinder to the Members'
Agreement and shall become bound by the terms and provisions thereof with
respect to the Option Units.

        Section 11. RESTRICTIVE LEGEND.

               All certificates representing Units issued upon exercise of the
Option shall, unless otherwise determined by the Committee, have affixed thereto
a legend substantially in the following form, in addition to any other legend
required by the Members' Agreement:

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

        Section 12. RIGHT TO REPURCHASE OPTION UNITS.

               (a) In the event of a Repurchase Event, the Company or its
designee shall have the right (but not the obligation) to repurchase from the
Optionee and any transferee thereof all of the Options or Option Units owned by
them.

               (b) The repurchase right of the Company or its designee under
this Section 12 may be exercised by written notice (a "Repurchase Notice"),
specifying the number of Option Units to


                                       5
<PAGE>   17

be repurchased, and given to the Optionee within 90 days of the Repurchase Event
or, in the event the Repurchase Notice states an intention to purchase Options,
within 90 days of the date upon which the Optionee either exercises or fails to
exercise such Options pursuant to the terms of this Agreement (or, if the
Company shall not have assigned its rights under this Section 12 and shall be
legally prevented from making such repurchase during such 90-day period, then
such Repurchase Notice may be delivered by the Company within 90 days after the
date on which it shall be legally permitted to make such repurchase). Upon the
delivery of a Repurchase Notice to the Optionee, the Optionee shall be obligated
to sell or cause to be sold to the Company or its designee the Option Units
specified in such Repurchase Notice.

               (c) The price per Option Unit to be paid under this Section 12
shall be determined as follows:

                      (i) if the Repurchase Event was triggered by (A) a
        Termination of Employment which arose out of a termination For Cause or
        (B) a Competition Event, then, the repurchase price shall be the lesser
        of (A) the price paid by the Optionee for the Option Units repurchased
        and (B) the Fair Value per Unit (net of the exercise price, in the case
        of Units consisting of options that have vested and are exercisable in
        accordance with the terms of the option agreement pursuant to which such
        options were granted);

                      (ii) if the Repurchase Event was triggered by the death of
        the Optionee, then, the repurchase price shall be the greater of (A) the
        price paid by the Optionee for the Option Units repurchased and (B) the
        Fair Value per Unit as of the Termination Option Units (net of the
        exercise price, in the case of consisting of options that have vested in
        accordance with the terms of the option agreement pursuant to which such
        options were granted); and

                      (iii) the repurchase price to be paid under this Section
        12 shall be paid by delivery of a subordinated promissory note (which
        shall be subordinated to all outstanding indebtedness of the Company) in
        a form reasonably acceptable to the Company, which note (x) shall have a
        three year term, with 10% of the principal being paid on the first and
        second anniversaries of the date thereof and the balance being paid on
        the third anniversary, (y) shall bear interest at a fluctuating rate per
        annum announced by The Chase Manhattan Bank, N.A. from time to time as
        its prime rate and (z) shall otherwise contain such terms and provisions
        as may be required by the Company's lenders.

               (d) Repurchases of Option Units under the terms of this Section
12 shall be made at the offices of the Company or its designee on a mutually
satisfactory business day within 30 days after the final determination of the
repurchase price as described above. Delivery of certificates or other
instruments evidencing such Option Units duly endorsed for transfer and free and
clear of all liens, claims and other encumbrances (other than those encumbrances
hereunder) shall be made on such date against payment of the purchase price
therefor or delivery of the promissory note, as the case may be.

               (e) The Optionee hereby acknowledges and recognizes that due to
his relationship with the Company he will be privy to trade secrets and
confidential proprietary information


                                       6
<PAGE>   18

about the management, policies and finances of the Company which are critical to
the Company's business. Accordingly, upon the occurrence of a Termination of
Employment and in consideration of the Option granted hereunder, the Optionee
agrees that, until the second anniversary of the date of such termination, he
will not (i) directly or indirectly engage in, represent in any way, or be
connected with, any business or activity which employs the Vista Technology
(such business or activity being hereinafter called a "Competing Business"),
directly competing with the Company's business, within any jurisdiction in which
the Company transacts business, whether such engagement shall be as an officer,
director, owner, employee, partner, affiliate or other participant in any
Competing Business, (ii) assist others in engaging in any Competing Business in
the manner described in the foregoing clause (i), (iii) induce the Company's
customers to change or alter in any manner their business dealings with the
Company or (iv) induce other employees of the Company or any subsidiary thereof
to terminate their employment with the Company or any subsidiary thereof, or
engage in any Competing Business (each of (i)-(iv), a "Competition Event"). The
Optionee understands that the foregoing restrictions may limit his ability to
earn a livelihood in a business similar to the business of the Company, but he
nevertheless believes that he has received sufficient consideration and other
benefits as a holder of an equity interest in the Company and understands that
the purchase price for his Option Units under this Section 12 reflects the
goodwill of the Company and that such benefits clearly justify these
restrictions which, in any event (given his education, skills and ability), he
does not believe would prevent him from earning a living.

               (f) Upon any Termination of Employment, all certificates
evidencing Option Units held by the Optionee or any transferee thereof shall be
delivered to the Company to be held in escrow as provided in this Section 12(f).
If such certificates are not so delivered by Optionee or any transferee thereof
to the Company within thirty (30) days after such Termination of Employment, the
Company shall have the right and option, exercisable in the manner provided in
Section 12(b) above, to purchase all Option Units held by the Optionee or any
transferee thereof at a cash price equal to the cost paid by the Optionee to
purchase such Option Units . The Option Units represented by such certificates
shall be held in escrow for a period of two years following any such Termination
of Employment. If the Optionee at any time breaches the provisions of Section
12(e), the Company shall have the right and option, exercisable in the manner
provided in Section 12(b) above, to purchase all such Option Units at a cash
price equal to the cost paid by the Optionee to purchase such Option Units. Upon
the completion of such two year period, and provided that no such breach of
Section 12(e) shall have occurred, such Option Units shall be released from such
escrow to the Optionee and shall not otherwise be subject to the provisions of
this Section 12. Any purchase of Option Units under this Section 12(f) shall be
made in accordance with Section 12(b).

        Section 13. OPTIONEE'S EMPLOYMENT.

               Nothing in the Option shall confer upon the Optionee any right to
continue in the employ of the Company or any of its Affiliates or interfere in
any way with the right of the Company or its Affiliates or equity holders, as
the case may be, to terminate the Optionee's or his affiliates' employment or to
increase or decrease the Optionee's or his affiliates' compensation at any time.

                             MUTUAL GENERAL RELEASE

               For a valuable consideration, the receipt and adequacy of which
are hereby acknowledged, Chuck Bastyr ("Employee"), and dj Orthopedics, LLC.
("Company") (collectively the "Parties") do hereby release and forever discharge
the "Releasees" herein, consisting of each other and each of their respective
parents, subsidiaries, and affiliates, and each of their respective associates,
owners, stockholders, predecessors, successors, heirs, assigns, employees,
agents, directors, officers, partners, representatives, lawyers, and all persons
acting by, through, under, or in concert with them, or any of them, of and from
any and all manner of action or actions, causes or causes of action, in law or
in equity, suits, debts, liens, contracts, agreements, promises, liabilities,
claims, demands, damages, losses, costs or expenses, of any nature whatsoever,
known or unknown, fixed or contingent (hereinafter called "Claims"), which they
now have or may hereafter have against the Releasees by reason of any and all
acts, omissions, events or facts occurring or existing prior to the date hereof,
except as expressly provided herein. The Claims released hereunder include,
without limitation, any alleged breach of any employment agreement; any alleged
breach of any covenant of good faith and fair dealing, express or implied; any
alleged torts or other alleged legal restrictions relating to the Employee's
employment and the termination thereof; and any alleged violation of any
federal, state or local statute or ordinance including, without limitation,
Title VII of the Civil Rights Act of 1964, as amended, the Federal Age
Discrimination in Employment Act of 1967, as amended, and the California Fair
Employment and Housing Act. This Release shall also not apply to Employee's
right to retirement and/or employee welfare benefits that have vested and
accrued prior to his separation from employment with the Company; Employee's
rights to indemnification under Section 2802 of the California Labor Code; or
the Parties' rights under the Employment and Separation Agreement and the
Consulting Agreement executed concurrently herewith.

               EMPLOYEE AND THE COMPANY ACKNOWLEDGE THAT HE AND IT ARE FAMILIAR
WITH THE PROVISIONS OF CALIFORNIA CIVIL CODE SECTION 1542, WHICH PROVIDES AS
FOLLOWS:

               "A GENERAL RELEASE DOES NOT EXTEND TO CLAIMS WHICH THE CREDITOR
               DOES NOT KNOW OR SUSPECT TO EXIST IN HIS FAVOR AT THE TIME OF
               EXECUTING THE RELEASE, WHICH, IF KNOWN BY HIM MUST HAVE
               MATERIALLY AFFECTED HIS SETTLEMENT WITH THE DEBTOR."

EMPLOYEE AND THE COMPANY BEING AWARE OF SAID CODE SECTION, HEREBY EXPRESSLY
WAIVES ANY RIGHTS HE AND/OR IT MAY HAVE THEREUNDER, AS WELL AS UNDER ANY OTHER
STATUTES OR COMMON LAW PRINCIPLES OF SIMILAR EFFECT.

               Employee agrees and expressly acknowledges that this Agreement
        includes a waiver and release of all claims that Employee has or may
        have under the Age Discrimination in Employment Act of 1967, as amended,
        29 U.S.C. ss. 621, et seq. ("ADEA"). The following terms and conditions
        apply to and are part of the waiver and release of the ADEA claims under
        this Agreement:

               (a) That this paragraph and this Agreement are written in a
        manner calculated to be understood by Employee.

               (b) The waiver and release of claims under the ADEA contained in
        this Agreement do not cover rights or claims that may arise after the
        date on which Employee signs this Agreement.

               (c) This Agreement provides for consideration in addition to
        anything of value to which Employee is already entitled.

               (d) Employee is advised to consult an attorney before signing
        this Agreement.

               (e) Employee is granted twenty-one (21) days after Employee is
        presented with this Agreement to decide whether or not to sign this
        Agreement. If Employee executes this Agreement prior to the expiration
        of such period, Employee does so voluntarily and after having had the
        opportunity to consult with an attorney.

               (f) Employee will have the right to revoke the waiver and release
of claims under the ADEA within seven (7) days of signing this Release. In the
event this Release is revoked, the Release and the Agreement executed
concurrently herewith will be null and void in their entirety.

               Manner of Revocation. In the event that Employee elects to revoke
this Mutual General Release, he shall deliver within the time period prescribed
above to the Company's President and Chief Executive Officer, a writing stating
that he is revoking this Mutual General Release and subscribed by the Employee.

               Consequences of Revocation. In the event that Employee should
elect to revoke this Mutual General Release as described in the paragraph above,
this Mutual General Release


                                       2
<PAGE>   24

shall be null and void in its entirety, and that certain Employment and
Separation Agreement and Consulting Agreement executed concurrently with this
Mutual General Release shall also be null and void in its entirety.

               The Parties represent and warrant to the Releasees that there has
been no assignment or other transfer of any interest in any Claim that the
Parties may have against the Releasees, or any of them. The Company agrees to
indemnify and hold the Releasees released by it harmless from any liability,
claims, demands, damages, costs, expenses and attorneys' fees incurred as a
result of any person asserting any such assignment or transfer of any rights or
claims under any such assignment or transfer from the Company. Employee agrees
to indemnify and hold harmless the Releasees released by him from any liability,
claims, demands, damages, costs, expenses and attorneys' fees incurred as a
result of any person asserting such assignment or transfer of any right or
claims under any such assignment or transfer from Employee.

               Each of the Parties agrees that if he or it hereafter commences,
joins in, or in any manner seek relief through any suit arising out of, based
upon, or relating to any of the Claims released hereunder or in any manner
asserts against the Releasees any of the Claims released hereunder, then the
party asserting such claim(s) will pay to the Releasees against whom such
claim(s) is asserted, in addition to any other damages caused thereby, all
attorneys' fees incurred by such Releasees in defending or otherwise responding
to said suit or Claim.

               The Parties further understand and agree that neither the payment
of money nor the execution of this Release shall constitute or be construed as
an admission of any liability whatsoever by the Releasees.
