         WHEREAS, Executive is and has been employed by Company and is currently
the Company's Senior Vice President of Sales and Marketing;

         WHEREAS, Company desires to continue to employ Executive and Executive

         WHEREAS, Company and Executive desire to amend and restate the Prior

agree as follows:

         1. Employment. Subject to the termination provisions contained in

referred to as the "Term"). If either the Company or Executive does not wish to
renew this Agreement when it expires at the end of any subsequent renewal term,
as hereinafter provided, or if either the Company or Executive wishes to renew
this Agreement on different terms than those contained herein, it or he shall
give written notice in accordance with Section 10.4 below of such intent to the

absence of such notice, this Agreement shall be renewed on the same terms and
conditions contained herein for a term of one (1) year from the date of

Directors of, any subsidiary or affiliate of the Company without any additional

business time and effort to the performance of the Executive's duties hereunder,
provided that in no event shall this sentence prohibit the Executive from

<PAGE>


         (iv)     All equity awards held by Executive at termination that vest
                  based on time shall become vested and all other terms of such
                  equity awards shall be governed by the plans and programs and

                  be entitled to continuation of health insurance coverage
                  (i.e., medical, dental and vision) under the Company's group
                  health plan(s) in which the Executive was participating on the
                  date of termination, or if such plan(s) have been terminated,
                  in the plan(s) in which senior executives of the Company
                  participate, for a period of nine (9) months after the date
                  Executive's employment terminates.

Payments and benefits under this Section 5.3 are subject to Section 5.6.

         5.4 Termination by Executive for Good Reason. Executive may terminate
his employment hereunder for Good Reason by providing written notice to the
Company. At the time Executive's employment is terminated by Executive for Good
Reason, the Term will terminate, all obligations of the Company and Executive
under Sections 1 through 3 will immediately cease (except as expressly provided
below), and the Company will pay Executive, and Executive will be entitled to
receive, the same compensation and rights specified in Section 5.3.

If any payment or benefit under this Section 5.4 is based on Annual Salary at
the time of Executive's termination and if a reduction in such Annual Salary was
the basis for Executive's termination for Good Reason, then the Annual Salary in
effect before such reduction shall be used to calculate payments or benefits
under this Section 5.4.

         5.6 Limitations Under Code Section 409A. Anything in this Agreement to
the contrary notwithstanding, if (A) on the date of termination of Executive's
employment with the Company or a subsidiary, any of the Company's stock is
publicly traded on an established securities market or otherwise (within the
meaning of Section 409A(a)(2)(B)(i) of the Internal Revenue Code, as amended
(the "Code")), (B) if Executive is determined to be a "specified employee"
within the meaning of Section 409A(a)(2)(B) of the Code, (C) the payments exceed
the amounts permitted to be paid pursuant to Treasury Regulations section
1.409A-1(b)(9)(iii) and (D) such delay is required to avoid the imposition of
the tax set forth in Section 409A(a)(1) of the Code, as a result of such
termination, the Executive would receive any payment that, absent the
application of this Section 5.6, would be subject to interest and additional tax
imposed pursuant to Section 409A(a) of the Code as a result of the application
of Section 409A(a)(2)(B)(i) of the Code, then no such payment shall be payable
prior to the date that is the earliest of (1) six (6) months after the
Executive's termination date, (2) the Executive's death or (3) such other date
as will cause such payment not to be subject to such interest and additional tax
(with a catch-up payment equal to the sum of all amounts that have been delayed
to be made as of the date of the initial payment).

It is the intention of the parties that payments or benefits payable under this
Agreement not be subject to the additional tax imposed pursuant to Section 409A
of the Code. To the extent such potential payments or benefits could become
subject to such Section 409A, the parties shall cooperate to amend this
Agreement with the goal of giving the Executive the economic benefits described
herein in a manner that does not result in such tax being imposed.

         7.1 Discoveries and Works. The Executive understands and agrees that
any and all Confidential Information (as hereinafter defined) of the Company
which he has access to, uses or creates during his employment with the Company
is and shall at all times remain the sole and exclusive property of the Company,
and the Executive further agrees to assign to the Company any right, title or
interest he may have in such Confidential Information to the Company. The
Executive also agrees that, if he is asked by the Company (at its expense), he
will do all things and sign all necessary documents reasonably necessary in the
opinion of the Company to eliminate any ambiguity as to the right of the Company
in such Confidential Information including but not limited to providing his full
cooperation to the Company in the event of any litigation to protect, establish
or obtain such rights of the Company.

The Executive understands that this Section 7.1 does not waive or transfer his
rights to any invention for which no equipment, supplies, facility or trade
secret or Confidential Information of the Company was used and which was
developed entirely on his own time, unless the invention relates to the business
of the Company, or to the Company's actual demonstratively anticipated research
or development, or the invention results from any work that he performed for the
Company during the Term.

The Executive hereby assigns and transfers to the Company, its successors, legal
representatives and assigns, his entire right, title, and interest in and to any
and all present and future works of authorship, inventions, know-how,
confidential information, proprietary information, or trade secrets resulting
from work done by him on behalf of the Company (collectively, the "Intellectual
Property"). The Executive agrees to waive all moral rights relating to the
Intellectual Property developed or produced, including without limitation any
and all rights of identification of authorship, any and all rights of approval,
restriction or limitation on use or subsequent modifications and any and all
rights to prevent any changes prejudicial to his honor or reputation. The
Executive further agrees to provide all assistance reasonably requested by the
Company in the establishment, preservation and enforcement of its rights in the
Intellectual Property, such assistance to be provided at the Company's expense,
but without any additional compensation to the Executive.

         7.2 Confidential Information. The Executive acknowledges that, during
the course of his employment with the Company, the Executive may receive special
training and/or may be given access to or may become acquainted with
Confidential Information (as hereinafter defined) of the Company. As used in
this Section 7.2, "Confidential Information" of the Company means all trade
practices, business plans, price lists, supplier lists, customer lists,
marketing plans, financial information, software and all other compilations of
information which relate to the business of the Company, or to any of its
subsidiaries, and which have not been disclosed by the Company to the public, or
which are not otherwise generally available to the public.

The Executive acknowledges that the Confidential Information of the Company, as
such may exist from time to time, are valuable, confidential, special and unique
assets of the Company and its subsidiaries, expensive to produce and maintain
and essential for the profitable operation of their respective businesses. The
Executive agrees that, during the course of his employment with the Company, or
at any time thereafter, he shall not, directly or indirectly, communicate,
disclose or divulge to any Person (as such term is hereinafter defined), or use
for his benefit or the benefit of any Person, in any manner, any Confidential
Information of the Company or its subsidiaries acquired during his employment
with the Company or any other confidential information concerning the conduct
and details of the businesses of the Company and its subsidiaries, except as
required in the course of his employment with the Company or as otherwise may be
required by law. For purposes if this Agreement, "Person" shall mean any
individual, partnership, corporation, trust, unincorporated association, joint
venture, limited liability company or other entity or any government,
governmental agency or political subdivision.

All documents relating to the businesses of the Company and its affiliates
including, without limitation, Confidential Information of the Company, whether
prepared by the Executive or otherwise coming into the Executive's possession,
are the exclusive property of the Company and such respective subsidiaries, and
must not be removed from the premises of the Company, except as required in the
course of the Executive's employment with the Company. The Executive shall
return all such documents (including any copies thereof) to the Company when the
Executive ceases to be employed by the Company or upon the earlier request of
the Company or the Board.

         7.3 Noncompetition; Non-Solicitation. During the Term of this Agreement
(including any extensions thereof) and for a period of one (1) year following
the termination of the Executive's employment under this Agreement for any
reason, which period shall be extended to eighteen (18) months if such
termination occurs in anticipation of a Change in Control (as defined in Section
6.2) or on or within eighteen (18) months after a Change in Control, the
Executive shall not, except with the Company's express prior written consent,
directly or indirectly, in any capacity, for the benefit of any entity or person
(including the Executive):

         (i)      Become employed by, own, operate, manage, direct, invest in
                  (except through a mutual fund or ownership of less than one
                  percent (1%) of the securities of a public company in
                  competition with the Business), or otherwise, directly or
                  indirectly, engage in, or be employed by, any entity or person
                  which competes with the Business (as hereinafter defined)
                  within the Territory. For purposes of this Agreement,
                  "Business" shall mean an image guided surgical device and/or
                  software used in combination with any surgical robotic device
                  and/or software in the field of orthopedics. For purposes of
                  this Agreement, "Territory" shall mean the United States of
                  America.

         (ii)     Divert or take away any customer or client of the Company, or
                  any of its subsidiaries, or solicit, service or promote a
                  competing service that competes with the Business to any
                  customer, client or employee of the Company, its subsidiaries
                  or any of its respective businesses.

         (iii)    Solicit or hire any employee of the Company, or any of its
                  subsidiaries.

         7.4 Cooperation With Regard to Litigation. Executive agrees to
cooperate with the Company, during the Term and thereafter (including following
Executive's termination of employment for any reason), by making himself
available to testify on behalf of the Company or any subsidiary or affiliate of
the Company, in any action, suit, or proceeding, whether civil, criminal,
administrative or investigative, and to assist the Company, or any subsidiary or
affiliate of the Company, in any such action, suit or proceeding, by providing
information and meeting and consulting with the Board or its representatives or
counsel, or representatives or counsel to the Company, or any subsidiary or
affiliate of the Company, as may be reasonably requested and after taking into
account Executive's post-termination responsibilities and obligations. The
Company agrees to reimburse Executive for all reasonable expenses actually
incurred in connection with his provision of testimony or assistance and if such
cooperation is provided more than one (1) year after Executive's termination of
employment, Executive shall be paid a reasonable per diem fee.

         7.5 Non-Disparagement. Executive shall not, at any time during the Term
and thereafter make statements or representations, or otherwise communicate,
directly or indirectly, in writing, orally, or otherwise, or take any action
which may, directly or indirectly, disparage or be damaging to the Company, its
subsidiaries or affiliates or their respective officers, directors, employees,
advisors, businesses or reputations, nor shall members of the Board of Directors
or Executive's successor in office, or other executive officers of the Company,
make any such statements or representations regarding Executive. Notwithstanding
the foregoing, nothing in this Agreement shall preclude Executive or his
successor or members of the Board of Directors or other executive officers of
the Company from making truthful statements that are required by applicable law,
regulation or legal process.

                                       11

<PAGE>



         7.6 Release of Employment Claims. Executive agrees, as a condition to
receipt of any termination payments and benefits provided for in Sections 4 and
5 herein (other than Compensation Accrued at Termination), that he will execute
a general release in substantially the form attached hereto as Exhibit B.

         7.7 Survival. The provisions of this Section 7 shall survive the
termination of the Term and any termination or expiration of this Agreement.

         7.8 Remedies. Executive agrees that any breach of the terms of this
Section 7 would result in irreparable injury and damage to the Company for which
the Company would have no adequate remedy at law; Executive therefore also
agrees that in the event of said breach or any threat of breach and
notwithstanding Section 9 the Company shall be entitled to an immediate
injunction and restraining order from a court of competent jurisdiction to
prevent such breach and/or threatened breach and/or continued breach by
Executive and/or any and all persons and/or entities acting for and/or with
Executive, without the necessity of posting any bond, but if a bond is
nonetheless required by the court entertaining the motion for the injunction,
the parties to this Agreement agree that a bond in the amount of one thousand
dollars ($1,000.00) is appropriate. The existence of any claim or cause of
action that the Executive or any such other person or entity may have against
the Company shall not constitute a defense or bar to the enforcement of any
provision under this Section 7. The availability of injunctive relief shall be
in addition to any other remedies to which the Company may be entitled at law or
in equity, but remedies other than injunctive relief may only be pursued in an
arbitration brought in accordance with Section 9.

         8. Reliance. The Executive acknowledges that his compliance with the
provisions of Sections 7.2 and 7.3 of this Agreement (hereinafter referred to as
the "Restrictive Covenants") is a material part of the consideration bargained
for by the Company under this Agreement. The Executive agrees that such
covenants are reasonable as to scope and duration and agrees to be bound by such
Restrictive Covenants to the maximum extent permitted by laws, it being the
intent and spirit of the parties to this Agreement that the Restrictive
Covenants hereof shall be enforceable. If the Restrictive Covenants shall for
any reason be held to be excessively broad as to duration, geographic scope,
property, subject or similar factor, then the court making such determination
shall have the power to reduce or limit such duration, geographic scope,
property, subject or similar factor so as to be enforceable to the maximum
extent compatible with applicable law, and the Restrictive Covenants shall then
be enforceable in their reduced or limited form.

         9. Governing Law; Disputes; Arbitration.

         9.1 Governing Law. This Agreement is governed by and is to be
construed, administered, and enforced in accordance with the laws of the
Florida, without regard to conflicts of law principles. If under the governing
law, any portion of this Agreement is at any time deemed to be in conflict with
any applicable statute, rule, regulation, ordinance, or other principle of law,
such portion shall be deemed to be modified or altered to the extent necessary
to conform thereto or, if that is not possible, to be omitted from this
Agreement. The invalidity of any such portion shall not affect the force,
effect, and validity of the remaining portion hereof. If any court determines
that any provision of Section 9 is unenforceable because of the duration or
geographic scope of such provision, it is the parties' intent that such court
shall have the power to modify the duration or geographic scope of such
provision, as the case may be, to the extent necessary to render the provision
enforceable and, in its modified form, such provision shall be enforced.

                                       12

<PAGE>



         9.2 Arbitration. Any dispute or controversy arising under or relating
to Sections 1 through 6 of this Agreement shall be settled exclusively by
arbitration in accordance with the National Rules for the Resolution of
Employment Disputes of the American Arbitration Association in effect at the
time of submission to arbitration, except the parties agree the matter shall be
handled by a single arbitrator. The award rendered in any arbitration proceeding
under this Section shall be final and binding. Judgment may be entered on the
arbitrators' award in any court having jurisdiction. Any demand for arbitration
must be made and filed within one hundred eighty days (180) days after the date
the requesting party knew or reasonably should have known of the event giving
rise to the controversy or claim. Any claim or controversy not submitted to
arbitration in accordance with this Section 9 shall be considered waived, and,
therefore, no arbitration panel or tribunal or court shall have the power to
rule or make any award on such claim or controversy. The prevailing party in any
arbitration proceeding pursuant to this Section 9 shall be entitled to recover
reasonable expenses, including attorney's fees and costs.

         10. Miscellaneous.

         10.1 Integration. This Agreement cancels and supersedes any and all
prior agreements and understandings between the parties hereto with respect to
the employment of Executive by the Company, any parent or predecessor company,
and the Company's subsidiaries during the Term, but excluding existing contracts
relating to compensation under executive compensation and employee benefit plans
of the Company and its subsidiaries. This Agreement constitutes the entire
agreement among the parties with respect to the matters herein provided, and no
modification or waiver of any provision hereof shall be effective unless in
writing and signed by the parties hereto. Executive shall not be entitled to any
payment or benefit under this Agreement that duplicates a payment or benefit
received or receivable by Executive under such prior agreements and
understandings or under any benefit or compensation plan of the Company.

         10.2 Successors and Assigns. This Agreement shall be assignable by the
Company, in its sole discretion:

         (i)      upon a sale or acquisition of the Company; or

         (ii)     to any affiliate of the Company,

without the Executive's consent and upon such assignment, shall inure to the
benefit of, and be binding upon, both the Executive and person or entity
purchasing such assets, business or goodwill, or surviving such merger or
resulting from such consolidation, or the successor company, as the case may be,
in the same manner and to the same extent as though such other person or entity
or the successor company were the Company. Neither this Agreement nor the rights
or obligations hereunder of the parties hereto shall be transferable or
assignable by Executive, except in accordance with the laws of descent and
distribution or as specified in Section 10.3. Notwithstanding the foregoing,
this Agreement shall be binding upon and shall inure to the benefit of the
parties to this Agreement and their respective personal representatives, heirs,
successors and assigns.

         10.7 No General Waivers. The failure of any party at any time to
require performance by any other party of any provision hereof or to resort to
any remedy provided herein or at law or in equity shall in no way affect the
right of such party to require such performance or to resort to such remedy at
any time thereafter, nor shall the waiver by any party of a breach of any of the
provisions hereof be deemed to be a waiver of any subsequent breach of such
provisions. No such waiver shall be effective unless in writing and signed by
