COMPENSATION. While you are employed by the Company, the Company will pay you a
base salary at the rate of $190,000 per year, in accordance with the usual

the Compensation Committee of the Board of Directors of the Company.

STOCK OPTIONS.

OPTION GRANT. The Company shall recommend to the Board of Directors of the
Company that the Board of Directors of the Company (or a duly authorized
committee thereof) grant to you an option (the "Option") to purchase 400,000
shares of the Company's common stock, par value $0.01 (the "Common Stock") under

law, be designated as an incentive stock option within the meaning of Section

allowable, the Option shall be a non-qualified stock option.

VESTING. The Option shall vest and become exercisable in four equal cumulative

Agreement and for the one year period following your termination of employment
for any reason (the "Restricted Period"), you will not, directly or indirectly,
without the prior written consent of the Company, enter into Competition with
the Company or any of its affiliates (the "Employer"). "Competition" means
participating, directly or indirectly, as an individual proprietor, partner,

consultant or in any capacity whatsoever in a business in the field of business
that the Employer is engaged in as of the date of your termination of employment
with the Company or is actively planning to engage in as of the date of your
termination of employment with the Company.

CONFIDENTIALITY. While you are employed by the Company and thereafter, you will
hold in a fiduciary capacity for the benefit of the Employer all secret or
confidential information, knowledge or data relating to the Employer, and their
respective businesses, which will have been obtained by you during your
employment by the Company and which will not be or become public knowledge
(other than by acts by you or your representatives in violation of this Letter
Agreement). You will not, except as may be required to perform your duties
hereunder or as may otherwise be required by law or legal process, without
limitation in time or until such information will have become public or known in
the Employer's industry (other than by acts by you or your representatives in
violation of this Letter Agreement), communicate or divulge to others or use,
whether directly or indirectly, any such information, knowledge or data
regarding the Employer, and their respective businesses.

<PAGE>

NON-SOLICITATION OF CUSTOMERS. During the Restricted Period, you will not,
directly or indirectly, influence or attempt to influence customers or suppliers
of the Employer to divert their business to any competitor of the Employer.

NON-SOLICITATION OF EMPLOYEES. You recognize that you possess and will possess
confidential information about other employees of the Employer relating to their
education, experience, skills, abilities, compensation and benefits, and
inter-personal relationships with customers of the Employer. You recognize that
the information you possess and will possess about these other employees is not
generally known, is of substantial value to the Employer in developing its
business and in securing and retaining customers, and has been and will be
acquired by you because of your business position with the Employer. You agree
that, during the Restricted Period, you will not, directly or indirectly,
solicit or recruit any employee of the Employer for the purpose of being
employed by you or by any competitor of the Employer on whose behalf you are
acting as an agent, representative or employee and that you will not convey any
such confidential information or trade secrets about other employees of the
Employer to any other person.

NON-DISPARAGEMENT. You shall not, or induce others to, Disparage the Employer or
any of their past and present officers, directors, employees or products.

Employer's employees or any individual or entity with whom the Employer has a
business relationship which would adversely affect in any manner: (i) the
conduct of the business of the Employer (including, without limitation, any
products or business plans or prospects); or (ii) the business reputation of the
Employer, or any of their products, or their past or present officers, directors
or employees.

INJUNCTIVE RELIEF. It is further expressly agreed that the Employer will or
would suffer irreparable injury if you were to compete with the Employer in
violation of this Letter Agreement and that the Employer would by reason of such
Competition be entitled to injunctive relief in a court of appropriate
jurisdiction and you further consent and stipulate to the entry of such
injunctive relief in such court prohibiting you from competing with the Employer
in violation of this Letter Agreement.

SURVIVAL OF PROVISIONS. The obligations contained in this paragraph 6 will
survive the termination of your employment with the Company and will be fully
enforceable thereafter. If it is determined by a court of competent jurisdiction
in any state that any restriction in this paragraph 6 is excessive in duration
or scope or extends for too long a period of time or over too great a range of
activities or in too broad a geographic area or is unreasonable or unenforceable
under the laws of that state, it is the intention of the parties that such
restriction may be modified or amended by the court to render it enforceable to
the maximum extent permitted by the law of that state or jurisdiction.

REPRESENTATIONS. You represent and warrant that your execution and performance
of this Letter Agreement will not be in violation of any other agreement to
which you are a party. Notwithstanding anything else herein, this Letter
