"Company" or "Employer").

     1.   Term of the Agreement. The term of this Agreement (the "Term") shall
commence on April 9, 2001, and shall continue in effect through April 8, 2003,

for a period of 180 days, as determined by an independent physician selected by
the Company and reasonably acceptable to you.

     (c)  Cause. Termination of your employment by the Company for "Cause" shall
mean termination upon (i) your continued failure to substantially perform your
duties with the Company (other than any such failure resulting from your
incapacity due to Disability) after a written demand for substantial performance

manner in which the company believes that you have not substantially performed
your duties, (ii) your dishonesty, conflict of interest, theft, embezzlement,
misappropriation of company assets, diversion of Company business opportunities,
or breach of your duties of loyalty to the Company, or (iii) you shall have been

provision of any confidentiality, nondisclosure, assignment of invention,
non-competition or similar agreement entered into by you in connection with your
employment by the Company. For purposes of this subsection, no act or failure to
act on your part shall be deemed "willful" unless done or omitted to be done by

was in the best interest of the Company.

equal to one (1) year's salary in a lump sum payment less applicable payroll
taxes on the next payroll date following date of separation. In addition, all

benefit plan whose beneficiaries are employees of the Company or any of its
subsidiaries) of the beneficial ownership (as defined in Rule 13d-3 of the
Exchange Act, in effect as of the date hereof) of forty percent (40%) or more
of the Common Stock of the company or securities representing forty percent
(40%) or more of the combined voting power of the voting securities of the

prior to such transaction or transactions; or (v) the election or appointment,
within a twelve (12) month period, of any person or affiliated or associated
group, or its or their nominees, to the Board of Directors of the Company, such

of the Board of Directors of the Company and whose appointment or election was
not approved by a majority of those persons who were directors at the beginning
of such period or whose election or appointment was made at the request of an
Acquiring Person. An "Acquiring Person" is any person who, or which, together
with all affiliates or associates of such person, is the beneficial owner of
twenty percent (20%) or more of the Common Stock of the Company then
outstanding, except than an Acquiring Person does not include the company or
any employee benefit plan of the Company or any of its subsidiaries or any
person holding Common Stock of the company for or pursuant to such plan. For
the purpose of determining who is an Acquiring Person, the percentage of the
outstanding shares of the Common Stock of which a person is a beneficial owner
shall be calculated in accordance with Rule 13d-e of the Exchange Act.

     (f)  Constructive Termination. "Constructive Termination" means the
voluntary termination of employment by the Employee following a Change of
Duties following a Change of Control.

     (h)  Notice of Separation. Notification of Employee's intent to
terminate employment with Company shall be communicated by a written Thirty-Day

of duties on a full-time basis.

     5.   Non-Disclosure/Restricted Covenants. Employee agrees that all
financial data, customer lists, plans, contracts, agreements, literature,
manuals, catalogs, brochures, books, records, computer files applications, maps,
correspondence, and other materials furnished or made available to the Employee
by the Employer, or any of its clients, or created, prepared or secured through

property of the Employer, and the Employee agrees to deliver all such materials,
including all copies thereof, to the Employer upon termination of the Employee's
employment hereunder. Upon separation, other than as expressly directed by the
Employer, Employee shall never, directly or indirectly, sell, use, disclose,

Company. In exchange for Employee's employment and the additional consideration
provided hereunder, for a period of one (1) year after separation date, the
Employee agrees that he will not (i) own or have any interest, directly or
indirectly, in or act as an officer, director, agent, employee, or consultant
of, or assist in any way or in any capacity, any person, firm association,
partnership, corporation, or other entity which sells or provides products or
services in competition with the Employer anywhere within the world where any
confidential information acquired by the Employee would reasonably be considered
advantageous to such other competing entity; or (ii) directly or indirectly
entice, induce, or in any manner influence any person who is, or shall be, in
the service of the Employer to leave such service for the purpose of engaging in
business or being employed by or associated with any person, form, association,
partnership, corporation, or other entity which is in competition with the
Employer. In the event that any court shall finally hold that the time or
territory or any other provision of this Paragraph constitutes an unreasonable
restriction against the Employee, the Employee agrees that the provisions hereof
shall not be rendered void but shall apply as to such time, territory, and other
extent as such court may determine to be a reasonable restriction under the
circumstances involved.

     6.   Miscellaneous.

paragraph 5 and the limitations imposed by Section 423(b) of the Code.

         (a)      Any provisions of the Plan to the contrary notwithstanding, no
Employee shall be granted an option under the Plan (i) if, immediately after the
grant, such Employee (or any other person whose stock would be attributed to
such Employee pursuant to Section 424(d) of the Code) would own stock and/or
hold outstanding options to purchase stock possessing five percent (5%) or more
of the total combined voting power or value of all classes of stock of the

equal to fifteen percent (15%) of his Compensation earned during the applicable
offering period, determined as of the date of the commencement of such offering)
by eighty-five percent (85%) of the fair market value of a share of the

market value of a share of the Common Stock of the Company on the Offering Date;
or (ii) eighty five percent (85%) of the fair market value of a share of the
Common Stock of the Company on the Exercise Date. The fair market value of the
Company's Common Stock on a given date shall be determined by the Board in its
discretion; provided, however, that where there is a public market for the
Common Stock, the fair market value per Share shall be the mean of the bid and
asked prices of the Common Stock for such date, as reported in the Wall Street
Journal (or, if not so reported, as otherwise reported by the National
Association of Securities Dealers Automated Quotation (NASDAQ) System) or, in
the event the Common Stock is listed on a stock exchange, the fair market value
per Share shall be the closing price on such exchange on such date, as reported
in the Wall Street Journal.

         Section 7. Exercise of Option. Unless a participant withdraws from the
Plan as provided in paragraph 9, his option for the purchase of shares will be
exercised automatically on the Exercise Date of the offering period, and the
maximum number of full shares subject to option will be purchased for him at the
applicable option price. The shares purchased upon exercise of an option
hereunder shall be deemed to be transferred to the participant on the Exercise
Date. During his lifetime, a participant's option to purchase shares hereunder
is exercisable only by him.

         Section 8. Delivery. Within 30 days after the Exercise Date of each
offering period, the Company shall arrange the delivery to each participant, as
appropriate, of a certificate representing the shares purchased upon exercise of
his option in exchange for payment in full by the Employee, on or before such
date as shall be determined by the Board or it committee, of the option price
for all shares so purchased.

         Section 9. Withdrawal; Termination of Employment. (a) A participant may

Employee prior to the Exercise Date of the offering period for any reason,
including retirement or death, his option will be automatically terminated.

         (c)      In the event an Employee fails to remain in Continuous Status
as an Employee of the Company for at least twenty (20) hours per week during the
offering period in which the employee is a participant, he will be deemed to
have elected to withdraw from the Plan and his option terminated.

         (d)      A participant's withdrawal from an offering will not have any
effect upon his eligibility to participate in a succeeding offering or in any
similar plan which may hereafter be adopted by the Company.

         Section 10. Stock. (a) The maximum number of shares of the Company's
Common Stock which shall be made available for sale under the Plan shall be (a)
1,300,000 shares plus (b) an annual increase to be added on June 1 of each year
(beginning June 1, 2001) equal to the

                                       3
<PAGE>
lesser of (i) 1,000,000 shares, (ii) 1% of the outstanding shares of the
Company, or (iii) a number of shares determined by the Board of Directors of the
Company, subject to adjustment upon changes in capitalization of the Company as
provided in paragraph 14. If the total number of shares which would otherwise be
subject to options granted pursuant to Section 6 hereof on the Offering Date of
an offering period exceeds the number of shares then available under the Plan
(after deduction of all shares for which options have been exercised or are then
outstanding), the Company shall make a pro rata allocation of the shares
remaining available for option grant in as uniform a manner as shall be
practicable and as it shall determine to be equitable. In such event, the
Company shall give written notice of such reduction of the number of shares
subject to the option to each Employee affected thereby.

         (b)      The participant will have no interest or voting right in
shares covered by his option until such option has been exercised.

         (c)      Shares to be delivered to a participant under the Plan will be
registered in the name of the participant or in the name of the participant and
his spouse.

         Section 11. Administration. The Plan shall be administered by the Board
of the Company or a committee of members of the Board appointed by the Board.
The administration, interpretation or application of the Plan by the Board or
its committee shall be final, conclusive and binding upon all participants.
Members of the Board who are eligible Employees are permitted to participate in
the Plan, provided that:

                  (a)      Members of the Board who are eligible to participate
         in the Plan may not vote on any matter affecting the administration of
         the Plan or the grant of any option pursuant to the Plan.

                  (b)      If a Committee is established to administer the Plan,
         no member of the Board who is eligible to participate in the Plan may
         be a member of the Committee.

         Section 12. Transferability. No rights with regard to the exercise of
an option or to receive shares under the Plan may be assigned, transferred,
pledged or otherwise disposed of in any way (other than by will or the laws of
descent and distribution) by the participant. Any such attempt at assignment,
transfer, pledge or other disposition shall be without effect, except that the
Company may treat such act as an election to withdraw from the Plan in
accordance with paragraph 9.

         Section 13. Reports. Individual accounts will be maintained for each
participant in the Plan. Statements of account will be given to participating
Employees promptly following the Exercise Date, which statements will set forth
the per share purchase price, the number of shares purchased and the amount due
the Company in payment of the option shares pursuant to paragraph 8.

         Section 14. Adjustments upon Changes in Capitalization. Subject to any
required action by the shareholders of the Company, the number of shares of
Common Stock covered by each option under the Plan which has not yet been
exercised and the number of shares of Common Stock which have been authorized
for issuance under the Plan but have not yet been placed under option
(collectively, the "Reserves"), as well as the price per share of Common

                                       4
<PAGE>
Stock covered by each option under the Plan which has not yet been exercised,
shall be proportionately adjusted for any increase or decrease in the number of
issued shares of Common Stock resulting from a stock split, reverse stock split,
stock dividend, combination or reclassification of the Common Stock, or any
other increase or decrease in the number of shares of Common Stock effected
without receipt of consideration by the Company; provided, however, that
conversion of any convertible securities of the Company shall not be deemed to
have been "effected without receipt of consideration." Such adjustment shall be
made by the Board, whose determination in that respect shall be final, binding
and conclusive. Except as expressly provided herein, no issue by the Company of
shares of stock of any class, or securities convertible into shares of stock of
any class, shall affect, and no adjustment by reason thereof shall be made with
respect to, the number or price of shares of Common Stock subject to an option.

         In the event of the proposed dissolution or liquidation of the Company,
the offering period will terminate immediately prior to the consummation of such
proposed action, unless otherwise provided by the Board. In the event of a
proposed sale of all or substantially all of the assets of the Company, or the
merger of the Company with or into another corporation, each option under the
Plan shall be assumed or an equivalent option shall be substituted by such
successor corporation or a parent or subsidiary of such successor corporation,
unless the Board determines, in the exercise of its sole discretion and in lieu
of such assumption or substitution, that the participant shall have the right to
exercise the option as to all of the optioned stock, including shares as to
which the option would not otherwise be exercisable. If the Board makes an
option fully exercisable in lieu of assumption or substitution in the event of a
merger or sale of assets, the Board shall notify the participant that the option
shall be fully exercisable for a period of fifteen (15) days from the date of
such notice, and the option will terminate upon the expiration of such period.

         The Board may, if it so determines in the exercise of its sole
discretion, also make provision for adjusting the Reserves, as well as the price
per share of Common Stock covered by each outstanding option, in the event that
the Company effects one or more reorganizations, recapitalizations, rights
offerings or other increases or reductions of shares of its outstanding Common
Stock, and in the event of the Company being consolidated with or merged into
any other corporation.

         Section 15. Amendment or Termination. The Board of Directors of the
Company may at any time terminate or amend the Plan. Except as provided in
paragraph 14, no such termination can affect options previously granted, nor may
an amendment make any change in any option theretofore granted which adversely
affects the rights of any participant, nor may an amendment be made without
prior approval of the shareholders of the Company (obtained in the manner
described in paragraph 17) if such amendment would increase the number of shares
that may be issued under the Plan.

         Section 16. Notices. All notices or other communications by a
participant to the Company under or in connection with the Plan shall be deemed
to have been duly given when received in the form specified by the Company at
the location, or by the person, designated by the Company for the receipt
thereof.

                                       5

         Section 17. Shareholder Approval. (a) Any required approval of the
shareholders of the Company shall be solicited substantially in accordance with
Section 14(a) of the Exchange Act and the rules and regulations promulgated
thereunder.

         (b)      If any required approval by the shareholders of the Plan
itself or of any amendment to increase the number of shares reserved for
issuance under the Plan is solicited at any time other than in the manner
described in paragraph 17(a) hereof, then the Company shall, at or prior to the
first annual meeting of shareholders held subsequent to the granting of an
option hereunder to an officer or director do the following:

                  (i)      furnish in writing to the holders entitled to vote
         for the Plan substantially the same information which would be required
         (if proxies to be voted with respect to approval or disapproval of the
         Plan or amendment were then being solicited) by the rules and
         regulations in effect under Section 14(a) of the Exchange Act at the
         time such information is furnished; and

                  (ii)     file with, or mail for filing to, the Securities and
         Exchange Commission four copies of the written information referred to
         in subsection (ii) hereof not later than the date on which such
         information is first sent or given to shareholders.

         Section 18. Conditions upon Issuance of Shares. Shares shall not be
issued with respect to an option unless the exercise of such option and the
issuance and delivery of such shares pursuant thereto shall comply with all
applicable provisions of law, domestic or foreign, including without limitation,
the Securities Act of 1933, as amended, the Securities Exchange Act of 1934, as
amended, the rules and regulations promulgated thereunder, and the requirements
of any stock exchange upon which the shares may then be listed, and shall be
further subject to the approval of counsel for the Company with respect to such
