performance of his duties. Notwithstanding anything contained in this Agreement

            2.2 Salary Increases/Bonuses.

                  2.2.1 The Board shall meet at least annually to review
Executive's performance. Based upon such review and such other factors as the
Board may consider, at the sole and absolute discretion of the Board, the Board
may determine to increase but not decrease Executive's Salary and/or to award
Executive a bonus (which bonus may be payable in cash or securities of the
Company, including, without limitation, options to purchase shares of the
Company's Common Stock) and up to $50,000, at the Board's option.

that the Board would not be obligated, under any circumstances, to award any
such increase in salary or bonus.

<PAGE>

                  (1) As a result of his current employment with the Company,
Executive has obtained and will obtain secret and confidential information
concerning the business of the Company and/or its subsidiaries and affiliates,
(referred to collectively in this Section 4 as the "Company"), including,
without limitation, financial information, designs and other proprietary rights,
trade secrets and "know-how," customers and sources of supply ("Confidential
Information").

                  (2) The Company will suffer substantial damage that will be
difficult to compute if, during the period of his employment with the Company or
thereafter, Executive should enter a business competitive with the Company or
divulge Confidential Information.

                  (3) The provisions of this Agreement are reasonable and
necessary for the protection of the business of the Company.

            4.2 Executive agrees that he will not at any time, either during the
term of this Agreement or thereafter, divulge to any person or entity any
Confidential Information obtained or learned by him as a result of his
employment with, or prior retention by, the Company, except (a) in the course of
performing his duties hereunder, (b) with the Company's express written consent;
(c) to the extent that any such information is in the public domain other than
as a result of Executive's breach of any of his obligations hereunder; or (d)
where required to be disclosed by court order, subpoena or other government
process. If Executive shall be required to make disclosure pursuant to the
provisions of clause (d) of the preceding sentence, Executive promptly, but in
no event more than 72 hours after learning of such subpoena, court order, or
other government process, shall notify, by personal delivery or by electronic
means, confirmed by mail, the Company and, at the Company's expense, Executive
shall: (i) take all reasonably necessary and lawful steps required by the
Company to defend against the enforcement of such subpoena, court order or other
government process, and (ii) permit the Company to intervene and participate
with counsel of its choice in any proceeding relating to the enforcement
thereof.

            4.3 Upon termination of his employment with the Company, Executive

information has been destroyed) all confidential memoranda, notes, records,
reports, manuals, drawings, blueprints and


                                       9
<PAGE>

other documents (and all copies thereof) relating to the business of the Company
and all property associated therewith, which he may then possess or have under
his control; provided, however, subject to Executive's obligations under this
Section 4, that Executive shall be entitled to retain copies of such documents
reasonably necessary to document his financial relationship (both past and
future) with the Company.

            4.4 During the one-year period following termination of Executive's
employment with the Company for any reason, Executive, without the prior written
permission of the Company, shall not, anywhere in the United States, (a) enter
into the employ of or render any services to any person, firm or corporation
engaged in any Competitive Business, as defined below; (b) engage in any
Competitive Business for his own account; (c) become associated with or
interested in any Competitive Business as an individual, partner, shareholder,
creditor, director, officer, principal, agent, employee, trustee, consultant,
advisor or in any other relationship or capacity; (d) employ or retain, or have
or cause any other person or entity to employ or retain, any person who was
employed or retained by the Company while Executive was employed by the Company;
or (e) solicit, interfere with, or endeavor to entice away from the Company, for
the benefit of a Competitive Business, any of its customers or other persons
with whom the Company has a contractual relationship or is otherwise doing
business or has done business during the term of this Agreement. Notwithstanding
the foregoing, nothing in this Agreement shall preclude Executive from investing
his personal assets in the securities of any corporation or other business
entity which is engaged in a Competitive Business if such securities are traded
on a national stock exchange or in the over-the-counter market and if such
investment does not result in his beneficially owning, at any time, more than
4.9% of the publicly-traded equity securities of such Competitive Business. In
the event Executive's employment is terminated by the Company without cause as
provided in Section 3.5(a) or by Executive for Good Reason as provided in
Section 3.5(b), then Executive's obligations under this Section 4.4 shall only
be in effect for so long as the Company complies with its obligation to pay
Executive in accordance with Section 3.5(a) or (b), whichever is applicable.

            4.5 If Executive commits a breach, or threatens to commit a breach,
of any of the provisions of Sections 4.2 or 4.4, the Company shall have the
right and remedy:


                                       10
<PAGE>

                  (1) to have the provisions of this Agreement specifically
enforced by any court having equity jurisdiction, it being acknowledged and
agreed by Executive that the services being rendered hereunder to the Company
are of a special, unique and extraordinary character and that any such breach or
threatened breach will cause irreparable injury to the Company and that money
damages will not provide an adequate remedy to the Company; and

                  (2) to require Executive to account for and pay over to the
Company all monetary damages suffered by the Company as the result of any
transactions constituting a breach of any of the provisions of Sections 4.2 or
4.4, and Executive hereby agrees to account for and pay over such damages to the
Company.

            Each of the rights and remedies enumerated in this Section 4.5 shall
be independent of the other, and shall be severally enforceable, and such rights
and remedies shall be in addition to, and not in lieu of, any other rights and
remedies available to the Company under law or equity.

            In connection with any legal action or proceeding arising out of
Section 4.4, the prevailing party in such action or proceeding shall be entitled
to be reimbursed by the other party for the reasonable attorneys' fees and costs
incurred by the prevailing party.

            4.6 If Executive shall violate any covenant contained in Section
4.4, the duration of such covenant so violated shall be automatically extended
for a period of time equal to the period of such violation.

            4.7 If any provision of Sections 4.2 or 4.4 is held to be
unenforceable because of the scope, duration or area of its applicability, the
tribunal making such determination shall have the power to modify such scope,
duration, or area, or all of them, and such provision or provisions shall then
be applicable in such modified form.

            4.8 The provisions of Section 4.2 shall survive the termination of
this Agreement for any reason.
