question of whether Employee's illness or incapacity is reasonably likely to

maintained by Employee, Employee's disability insurance carrier for
determination. In the event the Company or such insurance carrier determines
that Employee is subject to such an illness or incapacity, and is unable to
perform the essential elements of his position with or without a reasonable
accommodation by the Company, the Company shall have the right to terminate
Employee's employment ("Termination for Disability") by written notification to

of his accrued and unpaid salary as set forth in Section 3.1 of this Agreement
and any reasonable and necessary business expenses incurred by Employee in
connection with his duties hereunder, all to the date of termination.

     5.   Protection of the Company's Business. In consideration of his
employment by the Company, and recognizing the Company's concerns regarding the
protection of its business, Employee agrees as follows:

<PAGE>

          5.1  Non-Competition. Employee agrees that during the Non-Competition
Period, as defined hereinafter, he shall not enter into any agreement with, or
engage in, or be connected or associated with, or own any interest in, or work
for any individual, firm or corporation or other entity which is engaged in or
connected with any business which is in competition with the Company in the
continental United States or any other country in which the Company is doing
business or is reasonably expected to do business, unless he obtains the express
written approval of the Board in its sole discretion after full disclosure of
the nature of the intended arrangement. The "Non-Competition Period" means the
period of the Employee's employment during the Term and a period of one year
following the Employee's termination of employment for any reason.

          5.2  Non-Solicitation. Employee agrees that during the Non-Competition
Period, he shall not (a) encourage any employee of the Company or any of its
subsidiaries to leave employment with the Company or subsidiary or (b) solicit
any customers of the Company or any of its subsidiaries to reduce or no longer
do business with the Company, directly or indirectly.

          5.3  Non-Disclosure. Employee agrees not to disclose either during the
period of his employment hereunder or at any time thereafter to any person,
firm, or corporation any information that the Company desires to protect and
keep secret and confidential concerning the business or affairs of the Company
which he may have acquired in the course of, or as incident to, his employment
hereunder for his own benefit or to the detriment or intended detriment of the
Company.

          5.4  Injunction. Employee acknowledges that the Company is relying on
the provisions of this Section 5 to protect its legitimate business interests
and that the same are not an unreasonable restriction on him, and that monetary
damages will not be an adequate remedy to a breach of this Section, and that it
would be impossible for the Company to measure damages in the event of such a
breach. Therefore, Employee agrees that, in addition to other rights that the
Company may have, the Company is entitled to an injunction, without posting
bond, preventing Employee from doing any act that would be in breach of this
Section 5.
