customarily vested in the offices of the Chief Executive Officer and Chief

written consent of the Company, render any material services to any other
business concern. Executive will use his best efforts and abilities faithfully
and diligently to promote the Company's business interests.

      1.5 Except for routine travel incident to the business of the Company,

      which renders Executive, in the reasonable judgment of the Board, unable
      to perform his duties and obligations under this Agreement for 90 days in
      any 12-month period;

            (c) delivery to Executive of written notice of termination by the
      Company "for cause," by reason of: (i) the commission by Executive of a
      felony or any crime involving moral turpitude; (ii) any act of personal
      misconduct which is materially prejudicial or injurious to the financial
      or business interests of the Company; (iii) any willful failure to act in
      good faith in accordance with the policies of the Company or failure to
      comply with written instructions of the Chairman of the Board of
      Directors, or the Board of Directors as a whole; or (vi) any breach of any
      portion of this Agreement which is not curable or, if curable, is not

for any period during which a continuing Severance Payment is being paid to
Executive. All payments provided for in clauses (i), (ii), (iii) of the Section

period (i.e., the 6-month period following such termination, or greater period
following such termination).

without further compensation therefore, but at no cost or expense to Executive,
and whether during the term of this Agreement or thereafter, Executive will, at
times mutually agreed upon by Company and Executive, do all reasonable lawful
acts, including, but not limited to, the execution of papers and lawful oaths

reasonably cooperate in all proceedings and matters relating thereto.

      7.4 Records. Executive will keep complete and accurate accounts, notes,

restrictions and limitations applicable to any such invention conceived or
developed by him during the term of this Agreement and shall take any and all
further action which may be required to discharge such obligations and to comply
with such restrictions and limitations.

8.    NON-SOLICITATION, NON-INTERFERENCE AND NON-COMPETE COVENANTS.

      8.1 Non-solicitation and Non-interference. During the Term and for a
period of 12 months thereafter (the "RESTRICTED PERIOD"), Executive shall not
(a) induce or attempt to induce any employee of the Company, its subsidiaries or
affiliates to leave the employ of the Company or in any way interfere adversely
with the relationship between any such employee and the Company, its
subsidiaries or affiliates (b) induce or attempt to induce any employee of the
Company, its subsidiaries or affiliates to work for, render services or provide
advice to or supply confidential business information or trade secrets of the
Company, its subsidiaries or affiliates to any third person, firm or
corporation, or (c) induce or attempt to induce any customer, supplier,
licensee, licensor or other business relation of the Company, its subsidiaries
or affiliates, to cease doing business with the Company, its subsidiaries or

customer, supplier, licensee, licensor or other business relation and the
Company, its subsidiaries or affiliates.


                                       6
<PAGE>

      8.2 Non-Compete. During the Restricted Period, Executive shall not,
directly or indirectly, be or become interested in or associated with or
represent or otherwise render assistance or services to (as an officer,
director, stockholder, partner, member, consultant, owner, employee, agent,
creditor or otherwise) any business that is then, or which proposes to become, a
competitor of the Company, its subsidiaries or affiliates. The foregoing shall
not restrict Executive from the ownership, solely as an investment, of
securities of any business if such ownership is not as controlling person of
such business, not as a member a group that controls such business, and not as a
direct or indirect beneficial owner of 3% or more of any class of publicly
traded securities of such business. The foregoing shall also not restrict
Executive from working for any entity whose business includes a business that is
a competitor of the Company, its subsidiaries or affiliates, but only if the
competitive business is not the principal or predominant business of such entity
and the services of Executive to such entity do not relate, directly or
indirectly, to the competitive business conducted by such entity.

      8.3 Additional Consideration. As additional consideration for the
provisions of Sections 8.1 and 8.2, the Company agrees to pay Executive $10,000
per month during each month of the Restricted Period after the expiration or
termination of the Term.

      8.4 Severability. Whenever possible, each provision of this Section 8
shall be interpreted in such manner as to be fully effective and valid under
applicable law. Should a court determine that any provision of this Section 8
cannot be enforced as written under applicable law, it is the parties' intention
that the court exercises its equitable power to modify such provision in such
manner as to effectuate the parties' intention and enforce such provision to the
fullest extent possible under applicable law. Should any provision of this
Section 8 be invalid in its entirety under applicable law, such invalidity shall
not affect any other provision of this Section 8 but the remainder hereof shall
be effective as though such provision had not been contained herein.

      8.5 Disclosure of Restrictions. If Executive shall accept or commence
employment with, or agree to provide services to, any person (except a person
who is then affiliated with the Company) during the Restricted Period, on or
before the date of such acceptance or agreement (and before commencement of
employment or the provision of services), Executive shall deliver a copy of this
Section 8 to his proposed employer.

<PAGE>

9.    NON-DISPARAGEMENT.

      9.1 Executive will not during the Term or thereafter denigrate, ridicule
or intentionally criticize the Company, or any of its subsidiaries or affiliates
or any of their respective products or services, properties, employees, officers
or directors, including, without limitation, by way of news interviews or the
expression of personal views, opinions or judgments to the news media.

10.   RESIGNATION.

      10.1 Notwithstanding any other provision of this Agreement, upon the
termination of Executive's employment for any reason, unless otherwise requested
by the Board, he shall immediately resign from the Board, from all boards of
directors of all subsidiaries and affiliates of the Company of which he may be a
member, and as a trustee of, or fiduciary to, any employee benefit plans of the
Company, its subsidiaries and affiliates. Executive hereby agrees to execute any
and all documentation of such resignations upon request by the Company, but he
shall be treated for all purposes as having so resigned upon termination of his
employment, regardless of when or whether he executes any such documentation.

11.   COOPERATION.

      11.1 Following the termination or expiration of the Term, upon reasonable
request by the Company, Executive shall cooperate with the Company with respect
to any litigation or other dispute relating to any matter in which he was
involved or had knowledge during his employment with the Company. The Company
shall reimburse Executive for all reasonable out-of-pocket costs, such as
travel, hotel and meal expenses, incurred by Executive in providing any
cooperation pursuant to this Section 11.

12.   INJUNCTIVE RELIEF.

      12.1 Executive hereby recognizes, acknowledges and agrees that in the
event of any breach by Executive of any of his covenants, agreements, duties or
obligations contained in Sections 5, 6, 7, 8 and 9 of this Agreement, the
Company would suffer great and irreparable harm, injury and damage, the Company
would encounter extreme difficulty in attempting to prove the actual amount of
damages suffered by the Company as a result of such breach, and the Company
would not be reasonably or adequately compensated in damages in any action at
law. Executive therefore covenants and agrees that, in addition to any other
remedy the Company may have at law, in equity, by statute or otherwise, in the
event of any breach by Executive of any of his covenants, agreements, duties or
obligations contained in Sections 5, 6, 7, 8 and 9 of this Agreement, the
Company shall be entitled to seek and receive temporary, preliminary and
permanent injunctive and other equitable relief from any court of competent
jurisdiction to enforce any of the rights of the Company, or any of the
covenants, agreements, duties or obligations of Executive hereunder, and/or
otherwise to prevent the violation of any of the terms or provisions hereof, all
without the necessity of proving the amount of any actual damage to the Company
or any affiliate thereof resulting therefrom; provided, however, that nothing
contained in this Section 12 shall be deemed or construed in any manner
whatsoever as a waiver by the Company of any of the rights which the Company may
have against Executive at law, in equity, by statute or otherwise arising out
of, in connection with or resulting from the breach by Executive of any of his
covenants, agreements, duties or obligations hereunder.

13.   RESOLUTION OF DISPUTES.

      13.1 Except as otherwise provided in Section 12 hereof, any dispute
arising under or in connection with this Agreement shall be resolved by binding
arbitration before a single arbitrator, to be held in accordance with the rules
and procedures of the American Arbitration Association. Judgment upon the award
rendered by the arbitrator shall be final and subject to appeal only to the
extent permitted by law. Each party shall bear its or his own expenses incurred
in connection with any arbitration.
