individual resident at 1001 Oakwood Blvd., Round Rock, Texas 78681 (the
"EMPLOYEE" or the "EXECUTIVE").

                                   WITNESSETH

         WHEREAS, the Employee is employed by the Company as its Vice President
- Research and Development pursuant to an employment agreement dated August 26,

         WHEREAS, the Employee is a key executive of the Company and has been
selected by the Chief Executive Officer of the Company to be offered a
severance agreement; and

         WHEREAS, the Board believes that if the Company should receive or
learn of any proposal from a third person concerning a possible business
combination with the Company, or an acquisition of equity securities or a
substantial portion of the assets of the Company, it is important that the
Company should be able to rely upon the Executive to continue in his position
and that the Board and the Chief Executive Officer should be able to receive
and rely upon his advice as to the best interests of the Company and its
shareholders, without concern that the Executive might be distracted by any
personal uncertainties and risks created by such a proposal; and

         WHEREAS, should the Company receive any such proposals, in addition to
the Executive's regular duties, he may be called upon to assist in the
assessment of such proposal, to advise management and the Board whether such
proposals would be in the best interests of the Company and its shareholders,
and to take such other actions as the Board may determine to be appropriate;
and

         WHEREAS, the Company wishes to be assured that it will have the
continued dedication of the Executive and the availability of his advice and
counsel despite the possibility, threat or occurrence of a bid to take over
control of the Company; and

         WHEREAS, the Company wishes to induce the Executive to remain in the
employment of the Company under such circumstances; and

                                           in effect within one (1) year of the
                                           Termination Event, plus

                                           of any bonus plan, with respect to
                                           any year that has then ended which
                                           was or would have accrued to the
                                           Executive under any bonus plan then
                                           in effect but which has not yet been
                                           paid to him, plus

                                  (C)      an amount, payable in cash only
                                           notwithstanding the terms of any
                                           bonus plan, equal to the product of
                                           (aa) the average of the bonus paid
                                           or payable to the Executive for the
                                           two preceding years (whether same

                                           is 52, plus

                                  (D)      an amount equal to the product of
                                           (aa) the number of unused vacation
                                           days accrued by the Executive
                                           through the date of termination
                                           multiplied by (bb) a fraction the

                                           effect within one (1) year of the
                                           Termination Event and the
                                           denominator of which is 250;

                          (ii)    The Company will contribute in cash to any
                 retirement or saving plan in which the Executive is
                 participating, within thirty (30) days after the date of
                 termination, the maximum amount which the Company is permitted
                 to contribute based on the payments made pursuant to paragraph
                 (i) above and, at the Executive's election, will buy back the
                 stock held by the Executive in any such plan at its then fair
                 market value, depositing said value in cash into said plan;

                          (iii)   The Company will pay in cash to the Executive
                 within thirty (30) days after the date of termination a
                 severance payment in an amount equal to the sum of

                                  (A)      three hundred percent (300%) of his
                                           full base annual salary at the
                                           highest rate in effect within one
                                           (1) year of the Termination Event,
                                           plus

                                  (B)      three hundred percent (300%) of the
                                           average bonus paid or payable to him
                                           for the two (2) preceding years
                                           (whether same was paid in cash or
                                           its equivalent value);

                 provided that if the amount payable by the Company to the
                 Executive under this clause (iii), without regard to any other
                 payments or benefits payable to the Executive under this
                 Agreement or the Employment Agreement, would constitute an
                 "excess parachute payment" for the purposes of Sections 280G
                 and 4999 of the Internal Revenue Code then the amount payable
                 by the Company under this Section 2b as a severance benefit
                 will be "grossed up" by the amount necessary in order to
                 reimburse Executive for any taxes due as a result of such an
                 "excess parachute payment" as per section 6 hereof.

                          (iv)    The Company will amend or revise all stock
                 option plans and restricted stock awards to which the
                 Executive is a party, or grant appropriate waivers of any
                 restrictions contained in such plans and awards, so as to
                 remove all restrictions upon the exercise by the Executive of
                 such options or upon the ability of the Executive to sell any
                 shares of stock that are subject to any such options or
                 awards.  As part of such amendments or revisions, the Company
                 will accelerate the vesting period for Executive to an
                 immediate one hundred (100%) and shall allow the Executive the
                 option to exercise his options or stock awards either within
                 ninety (90) days of his effective termination date and such
                 option remain as an incentive stock option or before the
                 termination of the original option or stock award period and
                 have such options be converted automatically into
                 non-qualified stock options for purposes of the Internal
                 Revenue Code.

                          (v)     The Company will prepay in full if at all
                 possible, and if not possible, ensure to the satisfaction of
                 Executive maintenance in full force and effect for the benefit
                 of the Executive and his spouse and dependents (if covered
                 prior to the date of termination) in each case for a period
                 from the date of termination until

                 the later of the death of the Executive or his spouse, during
                 their period of their eligibility, all employee life, health,
                 accident, disability, medical and other employee welfare
                 benefits plans provided by the Company in which the Executive
                 or his spouse or his dependents are participating at the time
                 of the Executive's termination under the same terms and
                 conditions as then in effect; provided, that if the
                 Executive's or his spouse's or his dependents continued
                 participation is not permitted under the general terms of such
                 plans, the Company shall arrange to provide substantially
                 similar benefits;

                          (vi)    The Company will maintain for the benefit of
                 the Executive such policy of liability insurance, providing
                 protection to him as an officer, director, agent or employee
                 of the Company or its subsidiaries, as may from time to time
                 be purchased by the Company for officers and directors
                 generally as authorized by or in furtherance of the
                 indemnification provisions contained in the Company's bylaws.
                 Neither the insurance nor the Executive's right to
                 indemnification thereunder may be canceled by the Company
                 without his permission for a period of five years following
                 the date of termination under this Agreement; provided,
                 however, that the Company may obtain a substitute insurance
                 policy as long as the rights of indemnity to the Executive are
                 at least equivalent to the most favorable rights provided
                 under the policy in effect immediately prior to the date of
                 termination.

                 (b)      The Executive shall have no duty to mitigate, whether
         by seeking other employment or otherwise, any loss or damage suffered
         by him as a result of any failure by the Company to make any payment,
         or provide any benefit, to him under this Section 2.

3.       AGREEMENTS OF EXECUTIVE.

         The Executive covenants and agrees as follows:

                 (a)      Provision of services when Change of Control is
         threatened.  If any person begins a tender or exchange offer for
         voting securities of the Company, or circulates a proxy to
         shareholders of the Company or takes any other action for the purposes
         of effecting a Change of Control of the Company, then notwithstanding
         the terms of the Employment Agreement or any other agreement between
         the Executive and the Company the Executive will not voluntarily leave
         the employment of the Company and will render the services
         contemplated in the recitals to this Agreement until either (i) such
         person has abandoned or terminated his efforts to effect a Change of
         Control or (ii) three months have elapsed since the date on which a
         Change of Control has occurred.

                 (b)      Noncompetition. Without limiting the terms of any
         similar provision in the Employment Agreement or any other agreement
         between the Executive and the Company, if the Executive's employment
         with the Company is terminated under any circumstances that entitle
         the Executive to receive the payments and other benefits provided in
         Section 2, then for a period of one year (or six (6) months should
         Executive make the election in the





                                      -6-

         last sentence of Section 2.1 of the Employment Agreement) from the
         Termination Event the Executive will not:

                          (i)     have any interest in, whether as proprietor,
                 officer, director or otherwise (but excluding an interest by
                 way of employment only),

                          (ii)    act as an agent, broker or distributor for,
                 or as an adviser or consultant to,

                          (iii)   be employed in any senior managerial or
                 executive position by any corporation, partnership, limited
                 liability company or other business organization in which he
                 has responsibility for,

         any business (regardless of the form in which such business is
         conducted) which is engaged, or which he reasonably expects to become
         engaged, in the business of designing, manufacturing, distributing or
         selling artificial joints and limbs and other orthopedic implant
         devices in the United States; provided that the ownership by the
         Executive of not more than two percent (2%) of the shares of any
         publicly traded corporation or twenty percent (20%) of a privately
         held company shall not constitute a violation of this subsection (b).

                 (c)      Publications by Executive.  Without limiting the
         terms of any similar provision in the Employment Agreement or any
         other agreement between the Executive and the Company, if the
         Executive's employment with the Company is terminated under any
         circumstances that entitle the Executive to receive the payments and
         other benefits provided in Section 2, then

                          (i)     the Executive will refrain from making any
                 disparaging comments about the Company or any of its
                 affiliates, and

                          (ii)    for a period of one (1) year from the
                 Termination Event the Executive will not without the prior
                 written permission of the Company write or publish, or assist
                 in the writing or publication of, any books, articles or other
                 materials that would adversely affect the interests of the
                 Company or its affiliates.

                 (d)      Remedies.  The Executive acknowledges that any
         violation of this Section may cause irreparable harm to the Company,
         and that damages are not an adequate remedy, and the Executive
         therefore agrees that the Company shall be entitled to an injunction
         by any appropriate court in the appropriate jurisdiction, enjoining,
         prohibiting and restraining the Executive from the continuance of any
         such violation, in addition to any monetary damages which might occur
         by reason of the violation of this Agreement.

                 (e)      Independent.  The covenants set forth in the
         foregoing subsections (a), (b), (c), and (d) shall be deemed and shall
         be construed as separate and independent covenants, and should any
         part or provision of such covenants be held invalid, void or
         unenforceable





                                      -7-
<PAGE>   8
         by any court of competent jurisdiction, such invalidity, voidness, or
         unenforceability shall in no way render invalid, void, or
         unenforceable any other part or provision thereof or any separate
         covenant not declared invalid, void, or unenforceable.  This Agreement
         shall in that case be construed as if the void, invalid or
         unenforceable provisions were omitted.

4.       NOTICE OF TERMINATION.

         Any termination of the Executive's employment by the Company or its
successor in interest or by the Executive shall be communicated by a written
notice of termination to the other party, and shall specify the provision of
this Agreement relied upon and shall set forth in reasonable detail the
circumstances claimed to provide a basis for termination.  The date of
termination shall be the date on which the notice of termination is delivered
if by the Executive or thirty (30) days after the date of the notice of
termination if given by the Company.  All applicable benefits to Executive
hereunder shall be triggered if said notice of termination is given within the
three (3)-year period specified in Section 2(a) hereof.

5.       LITIGATION EXPENSES.

         The Company shall pay reasonable legal fees and expenses incurred by
the Executive as a result of his seeking to obtain or enforce any right or
benefit provided by this Agreement, promptly and from time to time, at his
request as such fees and expenses are incurred.

6.       EXCESS PARACHUTE PAYMENTS.

                 (a)      If any federal excise tax is imposed under Section
         4999 of the Internal Revenue Code of 1986, as amended (an "EXCISE
         TAX") on the Executive with respect to any payments or benefits
         provided under Section 2, the Company hereby agrees, subject to the
         exceptions and limitations set forth below, to pay the Executive such
         additional amount (the "ADDITIONAL AMOUNT") as is necessary to cause
         the Executive to realize the same net amount after the imposition of
         all federal income tax, estate tax and Excise Tax imposed on payments
         and benefits under Section 2 (and on such Additional Amount payable
         under this Section 6) that he would have realized had such federal
         income tax, estate tax, and Excise Tax not been imposed upon him with
         respect to such payments and benefits under Section 2 and this Section
         6; provided, however, that no such Additional Amount shall be due with
         respect to

                          (i)     any penalties, interest, or similar charges,
                 if any, assessed with respect to or arising out of any income
                 tax, estate tax, or Excise Tax due unless the Company delays
                 the payment contemplated herein to the Executive or

                          (ii)    any income tax or estate tax which would be
                 owing by the Executive in the absence of the imposition of the
                 Excise Tax.

                 (b)      The Company shall have the right to contest, but the
         Executive shall have no duty to contest, the assessment of any such
         taxes, but in any event, the Executive





                                      -8-
<PAGE>   9
         agrees to cooperate in any contest the Company chooses to make
         provided the Company shall pay the costs of any such contest.

7.       ASSIGNMENT; SUCCESSORS IN INTEREST.

                 (a)      General.  Except with the prior written consent of
         the Executive,

                          (i)     no assignment by operation of law or
                 otherwise by the Company of any of its rights and obligations
                 under this Agreement may be made other than to an entity in
                 common control with or a successor to all or a substantial
                 portion of the business of the Company (but then only if such
                 entity assumes by operation of law or by specific assumption
                 executed by the transferee and delivered to the Executive all
                 obligations and liabilities of the Company under this
                 Agreement);

                          (ii)    no transfer by operation of law or otherwise
                 by the Company of all or a substantial part of its business or
                 assets shall be made unless the obligations and liabilities of
                 the Company under this Agreement are assumed in connection
                 with such transfer either by operation of law or by specific
                 assumption executed by the transferee and delivered to the
                 Executive; and

                          (iii)   in any such event the Company shall remain
                 liable for the performance of all of its obligations under
                 this Agreement (which liability shall be a primary obligation
                 for full and prompt performance rather than a secondary
                 guarantee of collectibility of damages).

         Except for any transfer or assignment of rights under this Agreement,
         in whole or in part, upon the death of the Executive to his heirs,
         devisees, legatees or beneficiaries or except with the prior written
         consent of the Company, no assignment or transfer by operation of law
         or otherwise may be made by the Executive of any of his rights under
         this Agreement.

                 (b)      Binding Nature.  This Agreement shall be binding upon
         the parties to this Agreement and their respective legal
         representatives, heirs, devisees, legatees, beneficiaries and
         successors and assigns; shall inure to the benefit of the parties to
         this Agreement and their respective permitted legal representatives,
         heirs, devisees, legatees, beneficiaries and other permitted
         successors and assigns (and to or for the benefit of no other person
         or entity, whether an employee or otherwise, whatsoever); and any
         reference to a party to this Agreement shall also be a reference to a
         permitted successor or assign.

8.       MISCELLANEOUS.

                 (a)      This Agreement may not be varied, altered, or changed
         except by instrument in writing executed by the parties hereto.  The
         failure of any party to this Agreement at any time or times to require
         performance of any provision of this Agreement shall in no manner
         affect the right to enforce the same.  No waiver by any party to this
         Agreement of any provision (or of a breach of any provision) of this
         Agreement, whether





                                      -9-
<PAGE>   10
         by conduct or otherwise, in any one or more instances shall be deemed
         or construed either as a further or continuing waiver of any such
         provision or breach or as a waiver of any other provision (or of a
         breach of any other provision) of this Agreement.

                 (b)      Wherever possible each provision of this Agreement
         shall be interpreted in such manner as to be effective and valid but
         if any one or more of the provisions of this Agreement shall be
         invalid, illegal or unenforceable in any respect for any reason, the
         validity, legality or enforceability of any such provisions in every
         other respect and of the remaining provisions of this Agreement shall
         not be impaired.

                 (c)      This Agreement shall be governed by and interpreted
         in accordance with the laws of the State of Texas (without giving
         effect to any choice of law provisions) and enforceable in a court of
         competent jurisdiction in Travis County, Texas.

                 (d)      This Agreement and any benefits accruing to Executive
         hereunder shall be supplemental and additional to any and all benefits
         accruing to Executive pursuant to the Employment Agreement and any and
         all Stock Option or Stock Award Plans applicable to Executive.

         IN WITNESS WHEREOF, the Company has caused this Agreement to be
executed by its duly authorized officer and the Executive has hereunto set his
hand as of the date and year first written above.

         WHEREAS, the Employee and the Company entered into a Severance

alia, for certain payments to be made in the event that certain events occurred
with respect to the Employee's employment relationship with the Company;

         WHEREAS, the Employee and the Company desire that there be certain

         NOW THEREFORE, in consideration of the premises and other mutual
promises and covenants contained in this Amendment and for other good and
valuable consideration, the receipt and adequacy of which are hereby
