         SECTION 5. Termination of Employment. Notwithstanding the provisions of
Section 2, Employee's employment hereunder may terminate under any of the
following conditions:

                           A.       Death. Employee's employment under this
                  Agreement shall terminate automatically upon her death.

                           B.       Disability. Employee's employment under this
                  Agreement may be terminated due to her Disability.
                  "Disability" shall mean Employee's inability to substantially
                  perform her duties hereunder for any period of at least 180
                  consecutive days due to a physical or mental incapacity. The
                  date of termination due to Disability shall be the date
                  Employee elects to terminate her employment service due to
                  such Disability or, if earlier, the date the Board determines
                  that Employee has met the definition of Disability and given
                  written notice of such termination to Employee.

                           C.       Termination by Company Without Cause. The
                  Company may terminate Employee's employment hereunder without
                  Cause (as hereinafter defined) on 30 days' prior written
                  notice to Employee.

                           D.       Termination by Company for Cause. Employee's
                  employment hereunder may be terminated for Cause by the
                  Company. For purposes of this Agreement, "Cause" shall mean
                  (i) the willful and continued failure by Employee to
                  substantially perform Employee's duties with the Company
                  (other than any such failure resulting from Employee's
                  incapacity due to physical or mental illness), (ii) an act or
                  acts of dishonesty taken by Employee and intended to result in
                  personal enrichment of Employee at the expense of the Company,
                  (iii) willful violation by Employee of Employee's material
                  obligations under this Agreement, (iv) willful violation by
                  Employee of a material policy of the Company, including its
                  policies regarding professional and ethical conduct, (v)
                  Employee's commission of one or more acts that constitute a
                  felony, (vi) Employee is publicly censured by the Securities
                  Exchange Commission, or (vii) Employee commits one or more
                  acts of fraud as regards the Company. For purposes of clause
                  (i) of this definition, no act, or failure to act, on
                  Employee's part shall be deemed "willful" unless done, or
                  omitted to be done, by Employee not in good faith and without
                  reasonable belief that Employee's act, or failure to act, was
                  in the best interest of the Company. The determination of
                  whether Cause exists must be made by a resolution duly adopted
                  by the affirmative vote of not less than a majority of the
                  entire membership of the Board of Directors of the Company.

                           E.       Termination by Employee. Employee may
                  terminate her employment hereunder at any time on 30 days'
                  prior written notice to the Board.

                  Company shall be obligated to pay, and Employee shall be

                           reimbursement; and

                                    4.       any benefits to which she is

                           benefit plan or program, or applicable law.

                           B.       Upon termination of Employee's employment
                  pursuant to Section 5.C., the Company shall be obligated to
                  pay or provide, and Employee's estate or beneficiary shall be
                  entitled to receive:

                                    1.       all of the amounts and benefits

                           to 1.5 times the sum of (i) Employee's Base Salary,

                           Employee or (b) a lump sum payment equal to 1.5 times
                           Employee's Base Salary and, solely for purposes of
                           determining Employee's vesting under any Options, the
                           number of shares that would become vested under such
                           Options during the 12-month period following
                           Employee's termination date if Employee's employment
                           had continued during such period shall become vested
                           on her termination of employment date, whichever of
                           (a) or (b) is elected by Employee in writing to the
                           Company within five days of her termination date.

                           C.       In the event of any termination of
                  employment under Section 5, Employee shall be under no
                  obligation to seek other employment, and, except as provided
                  in Section 6.D, there shall be no offset against amounts due
                  Employee under this Agreement on account of any remuneration
                  attributable to any subsequent employment or self-employment
                  that she may obtain.

                           D.       The Company and Employee have previously or
                  contemporaneously with this Agreement entered into a Severance
                  Agreement which provides certain payments and benefits to
                  Employee upon a qualified termination of employment in
                  connection with a change of control of the Company.
                  Notwithstanding anything in this Agreement to the contrary, to
                  the extent Employee is entitled to receive any severance
                  payment or benefits under the Severance Agreement any

                                       -4-

<PAGE>

                  severance payment or benefits to which Employee is otherwise
                  entitled to receive under this Agreement shall be reduced or
                  offset by the severance payment or benefit payable under the
                  Severance Agreement in such manner as is appropriate, as
                  determined in good faith by the Board, to prevent a
                  duplication of such payment and benefits.

         SECTION 7. Indemnification. The Company agrees to indemnify Employee to
the fullest extent permitted by applicable law with respect to any acts or
non-acts she may have committed during the period which she was an officer,
director and/or employee of the Company or any subsidiary or affiliate thereof,
or of any other entity of which she served as an officer, director or employee
at the request of the Company.

         SECTION 8. Covenants of Employee. Employee covenants as follows:

                           A.       Confidentiality. During and after her
                  employment with the Company and its affiliates, Employee will
                  hold in confidence all confidential information and will not
                  disclose it to any person other than in connection with the
                  performance of her duties and obligations hereunder, except
                  with the specific prior written consent of the Board of
                  Directors or the Chief Executive Officer; provided, however,
                  that the parties agree that this Agreement does not prohibit
                  the disclosure of confidential information where applicable
                  law requires, including, but not limited to, in response of
                  subpoenas and/or orders of a governmental agency or court of
                  competent jurisdiction. In the event that Employee is
                  requested or becomes legally compelled under the terms of a
                  subpoena or order issued by a court of competent jurisdiction
                  or by a governmental body to make any disclosure of
                  confidential information, Employee agrees that she will (i)
                  immediately provide the Company with written notice of the
                  existence, terms and circumstances, surrounding such
                  request(s) so that the Company may seek an appropriate
                  protective order or other appropriate remedy, (ii) cooperate
                  with the Company in its efforts to decline, resist or narrow
                  such requests and (iii) if disclosure of such confidential
                  information is required in the opinion of counsel, exercise
                  reasonable efforts to obtain an order or other reliable
                  assurance that confidential treatment will be accorded to such
                  disclosed information. "Confidential information" means any
                  and all intellectual property of the Company (or any of its
                  affiliates), including but not limited to: (a) trade secrets

                  any information that the Company deems to be a trade secret is
                  found by a court of competent jurisdiction not to be a trade
                  secret for purposes of this Agreement, such information will,
                  nevertheless, be considered confidential information for
                  purposes of this Agreement, so long as it otherwise meets the
                  definition of confidential information. Employee hereby waives
                  any requirement that the Company submit proof of the economic
                  value of any trade secret or post a bond or other security.

                           C.       Proprietary Items. Employee will not remove
                  from the Company's premises (except to the extent such removal
                  is for purposes of the performance of Employee's duties at
                  home or while traveling, or except as otherwise specifically
                  authorized by the Company) any document, record, notebook,
                  plan, model, component, device, or computer software or code,
                  whether embodied in a disk or in any other form belonging to
                  the Company or used in the Company's business (collectively,
                  the "Proprietary Items"). All of the Proprietary Items,
                  whether or not developed by Employee, are the exclusive
                  property of the Company. Upon termination of her employment,
                  or upon the request of the Company during the Term, Employee
                  will return to the Company all of the Proprietary Items and
                  confidential information in Employee's possession or subject
                  to Employee's control, and Employee shall not retain any
                  copies, abstracts, sketches, or other physical embodiment,
                  including electronic or otherwise, of any of the Proprietary
                  Items or confidential information.

                           D.       Non-Competition and Non-Interference. During
                  the period of her employment with the Company or its
                  affiliates and for the one-year period after the termination
                  of her employment with the Company and its affiliates,
                  Employee will not, directly or indirectly:

                                    1.       without the express prior written
                           consent of the Board of Directors, own an interest
                           in, manage, operate, join, control, lend money or
                           render financial or other assistance to or
                           participate in or be connected with, as an officer,
                           employee, partner, stockholder, consultant or
                           otherwise, any person that competes with the Company
                           in the field of neurostimulation in a matter covered
                           by a patent assigned to or held by the Company;
                           provided, however, that following Employee's
                           termination of employment with the Company the
                           foregoing restriction shall apply only

                                       -6-

<PAGE>

                           to those areas where the Company is actually doing
                           business on the date of such termination of
                           employment; provided, further, that Employee may
                           purchase or otherwise acquire for passive investment
                           up to 3% of any class of securities of any such
                           enterprise if such securities are listed on any
                           national or regional securities exchange or have been
                           registered under Section 12(g) of the Securities
                           Exchange Act of 1934;

                                    2.       whether for Employee's own account
                           or for the account of any other person, (except for
                           the account of the Company and its affiliates),
                           solicit Business from any person known by Employee to
                           be a customer of the Company or its affiliates,
                           whether or not Employee had personal contact with
                           such person during Employee's employment with the
                           Company and its affiliates;

                                    3.       whether for Employee's own account
                           or the account of any other person, (i) solicit,
                           employ, or otherwise engage as an employee,
                           independent contractor, or otherwise, any person who
                           is an employee of the Company or an affiliate, or in
                           any manner induce, or attempt to induce, any employee
                           of the Company or its affiliate to terminate her
                           employment with the Company or its affiliate; or (ii)
                           interfere with the Company's or its affiliate's
                           relationship with any person who at any time during
                           the Term, was an employee, contractor, supplier, or
                           customer of the Company or its affiliate; or

                                    4.       at any time after the termination
                           of her employment, disparage the Company or its
                           affiliates or any shareholders, directors, officers,
                           employees, or agents of the Company or any of its
                           affiliates, so long as the Company does not disparage
                           Employee.

                           E.       Acknowledgements. The Company acknowledges
                  that it is providing Employee with confidential information in
                  order for Employee to perform her duties under this Agreement.
                  Employee acknowledges that (a) the services to be performed by
                  her under this Agreement are of a special, unique, unusual,
                  extraordinary, and intellectual character, and (b) the
                  provisions of this Section 8 are reasonable and necessary to
                  protect the confidential information, goodwill and other
                  business interests of the Company. If any covenant in this
                  Section 8 is held to be unreasonable, arbitrary, or against
                  public policy, such covenant will be considered to be
                  divisible with respect to scope, time, and geographic area,
                  and such lesser scope, time, or geographic area, or all of
                  them, as a court of competent jurisdiction may determine to be
                  reasonable, not arbitrary, and not against public policy, will
                  be effective, binding, and enforceable against Employee.
                  Employee hereby agrees that this covenant is a material and
                  substantial part of this Agreement and that: (i) the
                  geographic limitations are reasonable; (ii) the term of the
                  covenant is reasonable; and (iii) the covenant is not made for
                  the purpose of limiting competition per se and is reasonably
                  related to a protectable business interest of the Company. The
                  period of time applicable to any covenant in this Section 8
                  will be extended by the duration of any violation

                                       -7-

<PAGE>

                  by Employee of such covenant. The provisions of this Section 8
                  shall survive the termination of the Term of this Agreement.

         SECTION 9. Injunctive Relief and Additional Remedy. Employee
acknowledges that the injury that would be suffered by the Company as a result
of a breach of the provisions of Section 8 of this Agreement would be
irreparable and that an award of monetary damages to the Company for such a
breach would be an inadequate remedy. Consequently, the Company will have the
right, in addition to any other rights it may have, to obtain a temporary
restraining order and/or injunctive relief to restrain any breach or threatened
breach or otherwise to specifically enforce any provision of this Agreement.
Employee waives any requirement for the Company's securing or posting of any
bond in conjunction with any such remedies. Employee further agrees to and
hereby does submit to in personam jurisdiction before each and every court for
that purpose. Without limiting the Company's rights under this Section or any
other remedies of the Company, if Employee breaches any of the provisions of
Section 8 and such breach is proven in a court of competent jurisdiction, the
Company will have the right to cease making any payments or providing other
benefits otherwise due Employee under this Agreement.

         SECTION 10. Amendment; Waiver. The terms and provisions of this
Agreement may be modified or amended only by a written instrument executed by
each of the parties hereto, and compliance with the terms and provisions hereof
may be waived only by a written instrument executed by each party entitled to
the benefits thereof. No failure or delay on the part of any party in exercising
any right, power or privilege granted hereunder shall constitute a waiver
thereof, nor shall any single or partial exercise of any such right, power or
privilege preclude any other or further exercise thereof or the exercise of any
other right, power or privilege granted hereunder.

         SECTION 11. Entire Agreement. Except as contemplated herein and the
Severance Agreement referenced in Section 6.D., this Agreement constitutes the
entire agreement between the parties with respect to the subject matter hereof
and supersedes any and all prior or contemporaneous written or oral agreements,
arrangements or understandings between the Company and Employee.

         SECTION 12. Notices. All notices or communications hereunder shall be

                              EMPLOYMENT AGREEMENT

         This Employment Agreement (the "Agreement"), entered into effective as

Employee hereby accepts such employment, all upon the terms and conditions set

         SECTION 2. Term. Subject to the terms and conditions of this Agreement,
unless sooner terminated pursuant to Section 5 of this Agreement, Employee shall

                  committees of civic or charitable organizations or trade
                  associations, provided that such activities do not materially

         SECTION 4. Compensation.

                           A.       Base Salary. During the Term, Employee shall
                  receive an annual salary of $206,000 (the "Base Salary")
                  payable in accordance with the Company's general payroll
                  practices. Employee's Base Salary shall be reviewed prior to

                  in the discretion of the Compensation Committee of the Board
                  of Directors ("Compensation Committee"); provided, however,
                  that the Base Salary, as it may be increased at any time, may

                  completion of the applicable bonus year. Bonuses for Employee
                  shall be based on the achievement of such Company,
                  departmental and/or individual performance goals that may be
                  established for the applicable bonus year by the Compensation
                  Committee.

                  the Compensation Committee. Overachievement Bonuses shall be

                  Sales, Earnings per Share and Cash Flow objectives included in
                  the annual budget approved by the Board of Directors at the

                  short-term disability plans and other welfare and similar
                  plans and vacation policies under terms generally applicable

         SECTION 5. Termination of Employment. Notwithstanding the provisions of
Section 2, Employee's employment hereunder may terminate under any of the
following conditions:

                           A.       Death. Employee's employment under this
                  Agreement shall terminate automatically upon his death.

                           B.       Disability. Employee's employment under this
                  Agreement may be terminated due to his Disability.
                  "Disability" shall mean Employee's inability to substantially
                  perform his duties hereunder for any period of at least 180
                  consecutive days due to a physical or mental incapacity. The
                  date of termination due to Disability shall be the date
                  Employee elects to terminate his employment service due to
                  such Disability or, if earlier, the date the Board determines
                  that Employee has met the definition of Disability and given
                  written notice of such termination to Employee.

                           C.       Termination by Company Without Cause. The
                  Company may terminate Employee's employment hereunder without
                  Cause (as hereinafter defined) on 30 days' prior written
                  notice to Employee.

                           D.       Termination by Company for Cause. Employee's
                  employment hereunder may be terminated for Cause by the
                  Company. For purposes of this Agreement, "Cause" shall mean
                  (i) the willful and continued failure by Employee to
                  substantially perform Employee's duties with the Company
                  (other than any such failure resulting from Employee's
                  incapacity due to physical or mental illness), (ii) an act or
                  acts of dishonesty taken by Employee and intended to result in
                  personal enrichment of Employee at the expense of the Company,
                  (iii) willful violation by Employee of Employee's material
                  obligations under this Agreement, (iv) willful violation by
                  Employee of a material policy of the Company, including its
                  policies regarding professional and ethical conduct, (v)
                  Employee's commission of one or more acts that constitute a
                  felony, (vi) Employee is publicly censured by the Securities
                  Exchange Commission, or (vii) Employee commits one or more
                  acts of fraud as regards the Company. For purposes of clause
                  (i) of this definition, no act, or failure to act, on
                  Employee's part shall be deemed "willful" unless done, or
                  omitted to be done, by Employee not in good faith and without
                  reasonable belief that Employee's act, or failure to act, was
                  in the best interest of the Company. The determination of
                  whether Cause exists must be made by a resolution duly adopted
                  by the affirmative vote of not less than a majority of the
                  entire membership of the Board of Directors of the Company.

                           E.       Termination by Employee. Employee may
                  terminate his employment hereunder at any time on 30 days'
                  prior written notice to the Board.

         SECTION 6. Payments Upon Termination.

                           A.       Upon termination of Employee's employment
                  for any reason prior to the expiration of the Term, the
                  Company shall be obligated to pay, and Employee shall be
                  entitled to receive:

                                    1.       all accrued and unpaid Base Salary
                           to the date of termination;

                                    2.       any earned, but unpaid, bonuses for
                           the bonus year ending prior to the date of
                           termination;

                                    3.       all incurred but unreimbursed
                           business expenses for which Employee is entitled to
                           reimbursement; and

                                    4.       any benefits to which he is
                           entitled under the terms of any applicable employee
                           benefit plan or program, or applicable law.

                           B.       Upon termination of Employee's employment
                  pursuant to Section 5.C., the Company shall be obligated to
                  pay or provide, and Employee's estate or beneficiary shall be
                  entitled to receive:

                                    1.       all of the amounts and benefits
                           described in Section 6.A.; and

                                    2.       either (a) a lump sum payment equal
                                             to 1.5 times the sum of (i)
                           Employee's Base Salary, plus (ii) the most recent
                           annual bonus earned by Employee or (b) a lump sum
                           payment equal to 1.5 times Employee's Base Salary
                           and, solely for purposes of determining Employee's
                           vesting under any Options, the number of shares that
                           would become vested under such Options during the
                           12-month period following Employee's termination date
                           if Employee's employment had continued during such
                           period shall become vested on his termination of
                           employment date, whichever of (a) or (b) is elected
                           by Employee in writing to the Company within five
                           days of his termination date.

                           C.       In the event of any termination of
                  employment under Section 5, Employee shall be under no
                  obligation to seek other employment, and, except as provided
                  in Section 6.D, there shall be no offset against amounts due
                  Employee under this Agreement on account of any remuneration
                  attributable to any subsequent employment or self-employment
                  that he may obtain.

                           D.       The Company and Employee have previously or
                  contemporaneously with this Agreement entered into a Severance
                  Agreement which provides certain payments and benefits to
                  Employee upon a qualified termination of employment in
                  connection with a change of control of the Company.
                  Notwithstanding anything in this Agreement to the contrary, to
                  the extent Employee is entitled to receive any severance
                  payment or benefits under the Severance Agreement any

                                       -4-

<PAGE>

                  severance payment or benefits to which Employee is otherwise
                  entitled to receive under this Agreement shall be reduced or
                  offset by the severance payment or benefit payable under the
                  Severance Agreement in such manner as is appropriate, as
                  determined in good faith by the Board, to prevent a
                  duplication of such payment and benefits.

         SECTION 7. Indemnification. The Company agrees to indemnify Employee to
the fullest extent permitted by applicable law with respect to any acts or
non-acts he may have committed during the period which he was an officer,
director and/or employee of the Company or any subsidiary or affiliate thereof,
or of any other entity of which he served as an officer, director or employee at
the request of the Company.

         SECTION 8. Covenants of Employee. Employee covenants as follows:

                           A.       Confidentiality. During and after his
                  employment with the Company and its affiliates, Employee will
                  hold in confidence all confidential information and will not
                  disclose it to any person other than in connection with the
                  performance of his duties and obligations hereunder, except
                  with the specific prior written consent of the Board of
                  Directors or the Chief Executive Officer; provided, however,
                  that the parties agree that this Agreement does not prohibit
                  the disclosure of confidential information where applicable
                  law requires, including, but not limited to, in response of
                  subpoenas and/or orders of a governmental agency or court of
                  competent jurisdiction. In the event that Employee is
                  requested or becomes legally compelled under the terms of a
                  subpoena or order issued by a court of competent jurisdiction
                  or by a governmental body to make any disclosure of
                  confidential information, Employee agrees that he will (i)
                  immediately provide the Company with written notice of the
                  existence, terms and circumstances, surrounding such
                  request(s) so that the Company may seek an appropriate
                  protective order or other appropriate remedy, (ii) cooperate
                  with the Company in its efforts to decline, resist or narrow
                  such requests and (iii) if disclosure of such confidential
                  information is required in the opinion of counsel, exercise
                  reasonable efforts to obtain an order or other reliable
                  assurance that confidential treatment will be accorded to such
                  disclosed information. "Confidential information" means any
                  and all intellectual property of the Company (or any of its
                  affiliates), including but not limited to: (a) trade secrets
                  concerning the business and affairs of the Company (or any of
                  its affiliates), product specifications, data, know-how,
                  formulae, compositions, processes, designs, sketches,
                  photographs, graphs, drawings, samples, inventions and ideas,
                  past, current, and planned research and development, current
                  and planned manufacturing or distribution methods and
                  processes, customer lists, current and anticipated customer
                  requirements, price lists, market studies, business plans,
                  computer software and programs (including object code and
                  source code), computer software and database technologies,
                  systems, structures, and architectures (and related formulae,
                  compositions, processes, improvements, devices, know-how,
                  inventions, discoveries, concepts, ideas, designs, methods and
                  information), and any other information, however documented,
                  that is a trade secret under federal, state or other
                  applicable law; and (b) information concerning

                                       -5-

<PAGE>

                  the business and affairs of the Company (or any of its
                  affiliates) (which includes historical financial statements,
                  financial projections and budgets, historical and projected
                  sales, capital spending budgets and plans, the names and
                  backgrounds of key personnel, personnel training and
                  techniques and materials), however documented; and notes,
                  analysis, compilations, studies, summaries, and other material
                  prepared by or for the Company (or any of its affiliates)
                  containing or based, in whole or in part, on any information
                  included in the foregoing.

                           B.       Trade Secrets. Any trade secrets of the
                  Company will be entitled to all of the protections and
                  benefits under the federal and state trade secret and
                  intellectual property laws and any other applicable law. If
                  any information that the Company deems to be a trade secret is
                  found by a court of competent jurisdiction not to be a trade
                  secret for purposes of this Agreement, such information will,
                  nevertheless, be considered confidential information for
                  purposes of this Agreement, so long as it otherwise meets the
                  definition of confidential information. Employee hereby waives
                  any requirement that the Company submit proof of the economic
                  value of any trade secret or post a bond or other security.

                           C.       Proprietary Items. Employee will not remove
                  from the Company's premises (except to the extent such removal
                  is for purposes of the performance of Employee's duties at
                  home or while traveling, or except as otherwise specifically
                  authorized by the Company) any document, record, notebook,
                  plan, model, component, device, or computer software or code,
                  whether embodied in a disk or in any other form belonging to
                  the Company or used in the Company's business (collectively,
                  the "Proprietary Items"). All of the Proprietary Items,
                  whether or not developed by Employee, are the exclusive
                  property of the Company. Upon termination of his employment,
                  or upon the request of the Company during the Term, Employee
                  will return to the Company all of the Proprietary Items and
                  confidential information in Employee's possession or subject
                  to Employee's control, and Employee shall not retain any
                  copies, abstracts, sketches, or other physical embodiment,
                  including electronic or otherwise, of any of the Proprietary
                  Items or confidential information.

                           D.       Non-Competition and Non-Interference. During
                  the period of his employment with the Company or its
                  affiliates and for the one-year period after the termination
                  of his employment with the Company and its affiliates,
                  Employee will not, directly or indirectly:

                                    1.       without the express prior written
                           consent of the Board of Directors, own an interest
                           in, manage, operate, join, control, lend money or
                           render financial or other assistance to or
                           participate in or be connected with, as an officer,
                           employee, partner, stockholder, consultant or
                           otherwise, any person that competes with the Company
                           in the field of neurostimulation in a matter covered
                           by a patent assigned to or held by the Company;
                           provided, however, that following Employee's
                           termination of employment with the Company the
                           foregoing restriction shall apply only

                                       -6-

<PAGE>

                           to those areas where the Company is actually doing
                           business on the date of such termination of
                           employment; provided, further, that Employee may
                           purchase or otherwise acquire for passive investment
                           up to 3% of any class of securities of any such
                           enterprise if such securities are listed on any
                           national or regional securities exchange or have been
                           registered under Section 12(g) of the Securities
                           Exchange Act of 1934;

                                    2.       whether for Employee's own account
                           or for the account of any other person, (except for
                           the account of the Company and its affiliates),
                           solicit Business from any person known by Employee to
                           be a customer of the Company or its affiliates,
                           whether or not Employee had personal contact with
                           such person during Employee's employment with the
                           Company and its affiliates;

                                    3.       whether for Employee's own account
                           or the account of any other person, (i) solicit,
                           employ, or otherwise engage as an employee,
                           independent contractor, or otherwise, any person who
                           is an employee of the Company or an affiliate, or in
                           any manner induce, or attempt to induce, any employee
                           of the Company or its affiliate to terminate his
                           employment with the Company or its affiliate; or (ii)
                           interfere with the Company's or its affiliate's
                           relationship with any person who at any time during
                           the Term, was an employee, contractor, supplier, or
                           customer of the Company or its affiliate; or

                                    4.       at any time after the termination
                           of his employment, disparage the Company or its
                           affiliates or any shareholders, directors, officers,
                           employees, or agents of the Company or any of its
                           affiliates, so long as the Company does not disparage
                           Employee.

                           E.       Acknowledgements. The Company acknowledges
                  that it is providing Employee with confidential information in
                  order for Employee to perform his duties under this Agreement.
                  Employee acknowledges that (a) the services to be performed by
                  him under this Agreement are of a special, unique, unusual,
                  extraordinary, and intellectual character, and (b) the
                  provisions of this Section 8 are reasonable and necessary to
                  protect the confidential information, goodwill and other
                  business interests of the Company. If any covenant in this
                  Section 8 is held to be unreasonable, arbitrary, or against
                  public policy, such covenant will be considered to be
                  divisible with respect to scope, time, and geographic area,
                  and such lesser scope, time, or geographic area, or all of
                  them, as a court of competent jurisdiction may determine to be
                  reasonable, not arbitrary, and not against public policy, will
                  be effective, binding, and enforceable against Employee.
                  Employee hereby agrees that this covenant is a material and
                  substantial part of this Agreement and that: (i) the
                  geographic limitations are reasonable; (ii) the term of the
                  covenant is reasonable; and (iii) the covenant is not made for
                  the purpose of limiting competition per se and is reasonably
                  related to a protectable business interest of the Company. The
                  period of time applicable to any covenant in this Section 8
                  will be extended by the duration of any violation

                                       -7-

                  by Employee of such covenant. The provisions of this Section 8
                  shall survive the termination of the Term of this Agreement.

         SECTION 9. Injunctive Relief and Additional Remedy. Employee
acknowledges that the injury that would be suffered by the Company as a result
of a breach of the provisions of Section 8 of this Agreement would be
irreparable and that an award of monetary damages to the Company for such a
breach would be an inadequate remedy. Consequently, the Company will have the
right, in addition to any other rights it may have, to obtain a temporary
restraining order and/or injunctive relief to restrain any breach or threatened
breach or otherwise to specifically enforce any provision of this Agreement.
Employee waives any requirement for the Company's securing or posting of any
bond in conjunction with any such remedies. Employee further agrees to and
hereby does submit to in personam jurisdiction before each and every court for
that purpose. Without limiting the Company's rights under this Section or any
other remedies of the Company, if Employee breaches any of the provisions of
Section 8 and such breach is proven in a court of competent jurisdiction, the
Company will have the right to cease making any payments or providing other
benefits otherwise due Employee under this Agreement.

         SECTION 10. Amendment; Waiver. The terms and provisions of this
Agreement may be modified or amended only by a written instrument executed by
each of the parties hereto, and compliance with the terms and provisions hereof
may be waived only by a written instrument executed by each party entitled to
the benefits thereof. No failure or delay on the part of any party in exercising
any right, power or privilege granted hereunder shall constitute a waiver
thereof, nor shall any single or partial exercise of any such right, power or
privilege preclude any other or further exercise thereof or the exercise of any
other right, power or privilege granted hereunder.

         SECTION 11. Entire Agreement. Except as contemplated herein and the
Severance Agreement referenced in Section 6.D., this Agreement constitutes the
entire agreement between the parties with respect to the subject matter hereof
and supersedes any and all prior or contemporaneous written or oral agreements,
arrangements or understandings between the Company and Employee.

         SECTION 12. Notices. All notices or communications hereunder shall be

person or entity any rights, benefits or remedies of any kind or character

as a matter of law. The Company further agrees that, in the event of a sale of
assets or liquidation as described in the preceding sentence, it shall take
whatever action it legally can in order to cause such assignee or transferee to
expressly assume the liabilities, obligations and duties of the Company
hereunder.

         SECTION 15. Governing Law. This Agreement shall be governed by and
construed in accordance with the laws of the State of Texas (except that no

         SECTION 17. Headings. The headings of the sections contained in this
Agreement are for convenience only and shall not be deemed to control or affect

together shall constitute one and the same instrument.
