        ---------------------------------- -------------------------------- --------------------------------

                  The Grant will be earned based upon Performance Criteria
         achieved by the Company as defined below. At any time after the Company
         has implemented an effective Employee Stock Ownership Program, the
         Employee may opt to accept option grants in lieu of restricted Common
         Stock Grants of an equivalent value to the Common Stock Grant. The
         Employee may do so at each individual Grant date.

                  Each Grant is conditioned upon the Company achieving its
         year-end performance objectives for revenue and profitability, based on
         a plan to be ratified by the Board of Directors of the Company (the
         "Board") during regularly scheduled meetings for each of the applicable
         years. For example, whether Grant One occurs will be measured against
         the plan set forth by the Board in the first quarter of year 2004 for
         year 2004.

         The subject shares issued via each Grant are non-transferable and
         subject to forfeiture until vested in accordance with this agreement.

         (e) REGISTRATION RIGHTS - In the event of a registration of Company
         common stock following the Final Date, Employee shall have the right to
         participate in such registration at Company's expense. Additionally,
         for a period of five years from the date of this Agreement, Employee
         shall have preemptive rights in the event of any potentially dilutive
         event, such that Employee may, within a reasonable time, elect to
         participate in such dilutive event under the terms thereof to maintain
         Employee's then current percentage interest in the Company.

         an opinion of counsel satisfactory to the company that a sale of such
         shares is deemed not to be a distribution pursuant to 17 CFR 230.144
         ("RULE 144"). The Company may not make any notation on its records nor

         applicable prospectus delivery requirements under the Securities Act in
         any sale or transfer of the Employee's Shares by the Employee, neither
         the Employee's Shares nor any interest therein shall be sold, assigned
         or otherwise transferred, whether by operation of law or otherwise,
         except to the Company pursuant to this Agreement, provided that the
         Employee may transfer such shares to members of his or her immediate
         family for estate planning purposes so long as such transferees agree,
         in writing, to be bound by the terms of this agreement, and further
         provided that the Employee may sell up to seven hundred fifty thousand
         (750,000) of such Shares pursuant to Rule 144.

         The Company shall not be required to transfer any Shares on its books

         have been sold, assigned or otherwise transferred in violation of this
         Agreement.

         In the event that the Employee ceases to be employed by the Company,
         for any reason or no reason, with or without cause, the Company shall
         have the right and option to purchase from the Employee or his personal
         representative, as the case may be, for the sum of $0.01 per Share, up

         to the Employee (or his estate), within sixty (60) days after the
         Employee's last day of employment with the Company (the "TERMINATION
         DATE"), a written notice of exercise of the Repurchase Option. Such
         notice shall specify the number of Shares to be purchased and shall be
         accompanied by a check in the amount of the purchase price for such
         Shares. If, and to the extent that, the Repurchase Option is not
         exercised by so giving the aforementioned notice within such sixty (60)
         day period, the Repurchase Option shall automatically expire and
         terminate effective upon the expiration of the sixty (60) day period.
         The Company, upon termination or exercise of the Repurchase Option,
         shall deliver to the Employee (or his estate) a certificate

         delivered or sent by registered or certified mail, postage prepaid,
         return receipt requested to the Employee (or his estate) at his or her

         upon mailing.

5. CONFIDENTIAL INFORMATION - Except as permitted or directed by the Board,
during the term of the Employee's engagement or at any time thereafter, the
Employee shall not divulge, furnish or make accessible to anyone or use in any
way (other than in the ordinary course of the business of the Company) any
confidential or secret knowledge or information of the Company that the Employee
has acquired or become acquainted with or will acquire or become acquainted with
prior to the termination of the period of the Employee's engagement by the
Company (including engagement by the Company or any affiliated companies prior
to the date of this Agreement) whether developed by the Employee himself or by
others, concerning any trade secrets, confidential or secret designs, processes,
formulae, plans, devices or material (whether or not patented or patentable)
directly or indirectly useful in any aspect of the business of the Company, any
customer or supplier lists of the Company, any confidential or secret
development or research work of the Company, or any other confidential
information or secret aspects of the business of the Company. The Employee
acknowledges that the above-described knowledge or information constitutes a
unique and valuable asset of the Company and represents a substantial investment
of time and expense by the Company, and that any disclosure or other use of such
knowledge or information other than for the sole benefit of the Company would be
wrongful and would cause irreparable harm to the Company. Both during and after
the term of the Employee's engagement, the Employee will refrain from any acts
or omissions that would reduce the value of such knowledge or information to the
Company. The foregoing obligations of confidentiality shall not apply to any
knowledge or information that is now published and publicly available or which
subsequently becomes generally publicly known in the form in which it was
obtained from the Company, other than as a direct or indirect result of the

program or venture or to any commission, finder's fee or other compensation in
connection therewith other than the compensation to be paid to the Employee as
provided in this Agreement.

10. MISCELLANEOUS

         (a) COUNTERPARTS - This Agreement may be executed in separate
         counterparts, each of which will be an original and all of which taken

         hereto may execute this Agreement by signing any such counterpart.

         (b) SEVERABILITY - Whenever possible, each provision of this Agreement
         shall be interpreted in such a manner as to be effective and valid
         under applicable law but if any provision of this Agreement is held to
         be invalid, illegal or unenforceable under any applicable law or rule,
         the validity, legality and enforceability of the other provisions of
         this Agreement will not be affected or impaired thereby. In furtherance
         and not in limitation of the foregoing, should the duration or
         geographical extent of, or business activities covered by, any
         provision of this Agreement be in excess of that which is valid and
         enforceable under applicable law, then such provision shall be
         construed to cover only that duration, extent or activities which may
         validly and enforceably be covered.

         (c) ASSIGNABILITY - Neither this Agreement nor any right, remedy,
         obligation or liability arising hereunder or by reason hereof shall be
         assignable (including by operation of law) by either party without the
         prior written consent of the other party to this Agreement, except that
         the Company may, without the consent of the Employee, assign its rights
         and obligations under this Agreement to any corporation, firm or other
         business entity with or into which the Company may merge or
         consolidate, or to which the Company may sell or transfer all or
         substantially all of its assets, or of which 50% or more of the equity


                                       10


         investment and of the voting control is owned, directly or indirectly,
         by, or is under common ownership with, the Company. Provided such
         assignee explicitly assumes such responsibilities, after any such
         assignment by the Company, the Company shall be discharged from all
         further liability hereunder and such assignee shall thereafter be
         deemed to be the Company for the purposes of all provisions of this
         Agreement including this Section 10.

         of the Company or the Employee in exercising any right hereunder shall
         operate as a waiver of such right. No waiver, express or implied, by
