as of January 2, 2001.

11. NO OTHER RIGHTS TO COMPENSATION. You acknowledge that once the payments set

CyberGuard as employee or in any other capacity whatsoever through the
Termination Date.

12.CERTAIN COMMUNICATIONS. CyberGuard and you agree that neither of us will say,
write or communicate in any manner to any person or entity anything
substantially derogatory about the other, regardless of the truth or falsity of
the information. Of course, nothing in this section shall be construed to
prevent either party from testifying truthfully under oath if compelled to do so
by court order or other legal compulsion. In this connection, for purposes
hereof, "CyberGuard" means and includes CyberGuard Corporation, and its current
officers, directors, employees, affiliates and representatives.

13. NON-SOLICITATION. You agree that for six (6) months after the Termination

indirectly, for yourself or for any other person, firm, corporation,
partnership, association or other entity (a) attempt to employ, employ or enter
into any contractual arrangement with any employee or former employee of

currently targeted prospective customers of CyberGuard for the purpose of

Technologies, Inc., Check Point Software Technologies, Inc, Fore Systems, Inc.,

16. INJUNCTION/SPECIFIC PERFORMANCE SETOFF. You acknowledge that a breach of any
of the provisions of Sections 13, 14, or 15 hereof would result in immediate and

any such breach shall occur or be threatened or attempted, to a decree of
specific performance and to a temporary and permanent injunction, without the

either directly or indirectly, and that such right to injunction shall be
cumulative to whatever other remedies for actual damages to which the Company is
entitled. You further agree that the Company may set off against or recoup from

     WHEREAS, subject to the terms and conditions hereinafter set forth, the
Company wishes to retain the services of the Consultant, and the Consultant is

         NOW, THEREFORE, in consideration of the premises and the mutual

consideration, and intending to be legally bound hereby, the parties hereto
agree as follows:

         1.       TERM. Subject to the provisions for termination hereinafter
                  set forth, the Company hereby engages the Consultant, and the
                  Consultant hereby accepts such engagement by the Company, as a
                  consultant, on the basis as an independent contractor, for a
                  term commencing on the Effective Date and continuing for one
                  (1) year ("Term"). This Agreement will terminate upon
                  expiration of the Term and may be renewed only upon both
                  parties' written agreement.

         2.       DUTIES. During the Term, the Consultant shall perform such
                  services and complete such duties hereunder (i) as are
                  assigned to him by the Chief Executive Officer of the Company
                  ("CEO") and (ii) that are outside of the scope of the
                  Consultant's duties as the Chairman, or a member, of the
                  Company's Board of Directors.

         3.       FEES. During the Term and for the due and faithful performance
                  of the services contemplated by this Agreement, the Company
                  will pay the Consultant a fee in the amount of one thousand
                  U.S. dollars ($1,000.00) ("Fee") for each day the Consultant
                  provides services hereunder, as assigned by the CEO; provided,
                  however that the Consultant obtains a written approval from
                  the CEO prior to commencing any services hereunder. In support
                  of the Fees to be paid, the Consultant will submit appropriate
                  supporting documentation and monthly billing/invoice
                  documents.

         4.       EXPENSES. The Company will reimburse the Consultant for his
                  reasonable and necessary business expenses related to the
                  performance of duties hereunder. In support of expenses to be
                  reimbursed, the Consultant will submit appropriate supporting
                  documentation and receipts in accordance with Company policy
                  and monthly billing/invoice documents.

         5.       INDEPENDENT CONTRACTOR. The Consultant shall be and remain
                  only an independent contractor. Nothing contained herein shall
                  be deemed or construed to create any association, partnership,
                  joint venture, employer/employee relationship. The Consultant
                  shall not be eligible to participate in any benefit plans,
                  programs or arrangements made available to employees of the
                  Company. The Consultant expressly acknowledges and agrees that
                  he will not be treated and will not seek to be treated as an
                  employee of the Company for any purpose.

         6.       TERMINATION OF AGREEMENT. This Agreement may be terminated by
                  either party hereto at anytime upon thirty (30) days prior
                  written notice to the other party. This Agreement may be
                  terminated by the Company, and such termination will be
                  immediate, if the Company states as cause for the termination:
                  a material breach of this Agreement; or an act of gross
                  negligence or willful misconduct by the Consultant; or the
                  commission of a felony or other act that constitutes a
                  material breach of reasonable business ethics by the
                  Consultant ("Cause").

         no event shall CyberGuard's aggregate liability for damages arising
         from or in connection with this Agreement exceed the amount of the Fees
         payable by CyberGuard to Consultant under this Agreement during the
         three (3) month period preceding the date a claim arises.
         Notwithstanding anything to the contrary, in no event shall CyberGuard
         be liable for any indirect, incidental, consequential, special,
         punitive or exemplary damages arising out of or in connection with this
         Agreement.

8.       MISCELLANEOUS.

         (a)      The invalidity or unenforceability of any particular

                  shall not be assignable by either party, except upon prior
                  written consent by both parties to this Agreement, except that
                  the Company may assign its rights and delegate its duties
