                              PRELIMINARY STATEMENT

party delivers written notice to the other of its or his election not to renew,
subject to the terms set forth in section 6. The termination of the Term for any
reason shall end COOK's employment under this Agreement, but shall not terminate

terminates its relationship with COOK pursuant to a change of ownership of at
least fifty percent (50%) of the outstanding Common Stock of the Corporation (on

"Change in Ownership"), certain options and warrants to purchase Common Stock of
the Corporation included in the Initial Grant shall fully vest subject to the
following schedule:

     1.   During the Initial Term, 25,000 options or warrants will vest fully,
          (in addition to the 25,000 options or warrants that fully vest upon
          the execution of this Agreement).

     2.   During the Additional Term, 50,000 options or warrants will vest
          fully.

     7. Definitions.

     (a) "Cause" Defined. "Cause" means (i) willful malfeasance or willful
misconduct by COOK in connection with his employment; (ii) COOK's gross
negligence in performing any of his duties under this Agreement; (iii) COOK's
conviction of, or entry of a plea of guilty to, or entry of a plea of nolo
contendere with respect to, any felony (iv) COOK's material breach of any
written policy applicable to all employees adopted by the Corporation; or (v)
material breach by COOK of any of his agreements in this Agreement.

     (b) Disability Defined. "Disability" shall mean COOK's incapacity due to
physical or mental illness that results in his being unable to substantially
perform his duties hereunder for six consecutive months (or for six months out
of any nine-month period). During a period of Disability, COOK shall continue to
receive his base salary hereunder, provided that if the Corporation provides
COOK with disability insurance coverage, payments of COOK's base salary shall be
reduced by the amount of any disability insurance payments received by COOK due
to such coverage.

     8. Confidentiality.

     (a) "Corporation Information" Defined. "Corporation Information" means all
information, knowledge or data of or pertaining to (i) the Corporation, its
employees and all work undertaken on behalf of the Corporation, and (ii) any
other person, firm, corporation or business organization with which the
Corporation may do business during the Term, that is not in the public domain
(and whether relating to methods, processes, techniques, discoveries, pricing,
marketing or any other matters).

     (b) Confidentiality. COOK hereby recognizes that the value of all trade
secrets and other proprietary data and all other information of the Corporation
not in the public

                                        3

<PAGE>


domain disclosed by the Corporation in the course of his employment with the
Corporation is attributable substantially to the fact that such confidential
information is maintained by the Corporation in strict confidentiality and
secrecy and would be unavailable to others without the expenditure of
substantial time, effort or money. COOK therefore, except as provided in the
next two sentences, covenants and agrees that all Corporation Information shall
be kept secret and confidential at all times during and after the end of the
Term and shall not be used or divulged by him outside the scope of his
employment as contemplated by this Agreement, except as the Corporation may
otherwise expressly authorize by action of the Board. In the event that COOK is
requested in a judicial, administrative or governmental proceeding to disclose
any of the Corporation Information, COOK will promptly so notify the Corporation
so that the Corporation may seek a protective order or other appropriate remedy
and/or waive compliance with this Agreement. If disclosure of any of the
Corporation Information is required, COOK may furnish the material so required
to be furnished, but COOK will furnish only that portion of the Corporation
Information that legally is required.

     9. Successors and Assigns.

     (a) COOK. This Agreement is a personal contract, and the rights and
interests that the Agreement accords to COOK may not be sold, transferred,
assigned, pledged, encumbered, or hypothecated by him. All rights and benefits
of COOK shall be for the sole personal benefit of COOK, and no other person
shall acquire any right, title or interest under this Agreement by reason of any
sale, assignment, transfer, claim or judgment or bankruptcy proceedings against
COOK. Except as so provided, this Agreement shall inure to the benefit of and be
binding upon COOK and his personal representatives, distributees and legatees.

     (b) The Corporation. This Agreement shall be binding upon the Corporation
and inure to the benefit of the Corporation and of its successors and assigns.

     10. Entire Agreement. This Agreement represents the entire agreement
between the parties concerning COOK's employment with the Corporation and
supersedes all prior negotiations, discussions, understandings and agreements,
whether written or oral, between COOK and the Corporation relating to the
subject matter of this Agreement.

     11. Amendment or Modification, Waiver. No provision of this Agreement may
be amended or waived unless such amendment or waiver is agreed to in writing
signed by COOK and by a duly authorized officer of the Corporation. No waiver by
any party to this Agreement of any breach by another party of any condition or
provision of this Agreement to be performed by such other party shall be deemed
a waiver of a similar or dissimilar condition or provision at the same time, any
prior time or any subsequent time.

writing and delivered personally or sent by overnight courier or registered or

     13. Severability. If any provision of this Agreement or the application of
any such provision to any party or circumstances shall be determined by any
court of competent jurisdiction to be invalid and unenforceable to any extent,

person or circumstances other than those to which it is so determined to be
invalid and unenforceable shall not be affected, and each provision of this
Agreement shall be validated and shall be enforced to the fullest extent
permitted by law. If for any reason any provision of this Agreement containing
restrictions is held to cover an area or to be for a length of time that is
unreasonable or in any other way is construed to be too broad or to any extent
invalid, such provision shall not be determined to be entirely null, void and of
no effect; instead, it is the intention and desire of both the Corporation and
COOK that, to the extent that the provision is or would be valid or enforceable
under applicable law, any court of competent jurisdiction shall construe and
interpret or reform this Agreement to provide for a restriction having the
maximum enforceable area, time period and such other constraints or conditions
(although not greater than those contained currently contained in this
Agreement) as shall be valid and enforceable under the applicable law.

     14. Survivorship. The respective rights and obligations of the parties
hereunder shall survive any termination of this Agreement to the extent
necessary to the intended preservation of such rights and obligations.

     15. Headings. All descriptive headings of sections and paragraphs in this
Agreement are intended solely for convenience of reference, and no provision of
this Agreement is to be construed by reference to the heading of any section or
paragraph.

     16. Withholding Taxes. All salary, benefits, reimbursements and any other
payments to COOK under this Agreement shall be subject to all applicable payroll
and withholding taxes and deductions required by any law, rule or regulation of
and federal, state or local authority.

     17. Counterparts. This Agreement may be executed in one or more
counterparts, each of which shall be deemed to be an original but all of which
together constitute one and same instrument.

     18. Applicable Law: Jurisdiction. The laws of the State of New York shall
govern the interpretation, validity and performance of the terms of this
Agreement, without reference to rules relating to conflicts of law. Any suit,
action or proceeding against COOK with respect to this Agreement, or any
judgment entered by any court in respect thereof, may be brought in any court of
competent jurisdiction in the State of New York, as the Corporation may elect in
its sole discretion, and COOK hereby submits to the exclusive jurisdiction of
such courts for the purpose of any such suit, action, proceeding or judgment.


     IN WITNESS WHEREOF, the parties hereto have executed this Agreement as of
the date first written above.
