         date of this Agreement, commissions for Product sales, if any, to that
         Customer are payable to Marketlink for six (6) months following the
         "House Account" designation. In the event that the newly added customer
         to the House Account list is an affiliate of a previously herein

         a resolution of the applicable commission payments, if any.

3.       COMPENSATION

         appropriate commission applied to actual partial or full payments, less
         fees incurred in the process of collecting the payments, subsequently

         Company's House Accounts hereunder and, notwithstanding anything to the
         contrary herein, no commissions for sales to those end users will be
         payable to Marketlink effective from the date those end users become

         business.

     B.  The Confidential Information shall be kept confidential by each party
         except that each party may disclose the Confidential Information or
         portions thereof to those of its directors, officers, employees,
         contractors, agents and representatives (collectively,
         "Representatives") who (i) absolutely need to know such Confidential
         Information and (ii) have previously agreed in writing to be bound by
         the terms and conditions as protective of the Confidential Information
         as those in this Agreement. Each party hereto agrees to be responsible
         for any breach of this Agreement by its Representatives. Each party
         shall also use the same degree of care to avoid disclosure of such
         Confidential Information as such party employs with respect to its own
         Confidential Information of like importance, but in no event less than
         reasonable care. Each party shall hold in confidence, and shall take
         all reasonable measures

         to prevent disclosure of the Confidential Information by its
         Representatives, and not disclose, to any third party for any reason or
         purpose whatsoever any materials which contain Confidential Information
         (regardless of who prepared such materials), and whether oral or in
         writing or other medium, or copies thereof, and whether acquired from
         the other party or acquired through inspection of the other party's
         property.

     C.  Marketlink agrees not to trade in the securities on the basis of the
         Confidential Information which it receives from CyberGuard under this
         Agreement. Marketlink acknowledges that a violation of this Section 15
         may constitute a violation of the securities laws and regulations by
         Marketlink.

     D.  Each of the parties hereto acknowledges that irreparable harm, for
         which there would be no adequate remedy at law, would arise from a
         violation of this Agreement, which would give rise to a right to an
         injunction in favor of the non-breaching party. Notwithstanding the
         foregoing, the parties are entitled to pursue any appropriate remedies
         at law or in equity for breach of this Agreement.

     E.  With respect to the Confidential Information, neither party shall (nor
         shall any Representative of a party) create, produce or develop in any
         manner, nor shall a party copy, photograph or reproduce in any manner,
         in whole or in part, the Confidential Information of such other party,
         without the prior written consent of the other party.

     F.  "Confidential Information" includes, but shall not be limited to, the
         Products, trade secrets, policies, procedures, techniques, designs,
         drawings, know-how, technical information, specifications, computer
         software, intellectual property, information and data relating to the
         development, research, testing, manufacturing, costs, marketing and
         uses of the products and services developed, manufactured or sold by a
         party hereto, each party's budgets and strategic plans, and the
         identity and special needs of customers for the products and services
         relating to each party's databases, data, all technology relating to
         each party's business, systems, methods of operation, customer lists,
         customer information, business and financial information, solicitation
         leads, marketing and advertising materials, methods and manuals and
         forms, all of which pertain to the activities or operations of each
         party.

     G.  Notwithstanding the foregoing, information shall not be deemed
         Confidential Information and the receiving party shall have no
         obligation with respect to any such information which: (a) is already
         known to the receiving party, and such prior knowledge can be
         demonstrated through physical evidence that pre-dates the date of
         disclosure and such prior knowledge was not gained through a
         confidential disclosure; (b) is or becomes publicly known through
         publication or otherwise and through no wrongful act of receiving
         party; (c) is received from a third party without similar restriction
         and without a breach of this Agreement; (d) is furnished to a third
         party by the disclosing party without a similar restriction on the
         third party's rights; (e) is approved for release by written
         authorization of the disclosing party (so long as such release complies
         with any requirements of the authorization); or (f) is disclosed
         pursuant to the lawfully imposed requirement of a governmental agency
         or disclosure is required by operation of law.

     H.  In the event that either party or any of its Representatives become
         legally compelled to disclose any of the Confidential Information of
         the other party, it shall provide the other party with prompt prior
         written notice so that the other party may seek a protective order or
         other appropriate remedy and/or waive compliance with the terms of this
         Agreement. In the event that such protective order or other remedy is
         not obtained, or that the other party waives compliance with the
         provisions hereof, the receiving party agrees to furnish only that
         portion of the Confidential Information which, as advised by written
         opinion of counsel, is legally required and to exercise its best
         efforts to obtain assurance that confidential treatment will be
         accorded such Confidential Information including filing any requests
         for confidential treatment as may be afforded under any law, rule or
         regulation. In any event, neither party nor any of their
         Representatives will oppose action by the other party to obtain an

<PAGE>   9

         appropriate protective order or other reliable assurance that
         confidential treatment be accorded the Confidential Information.

     I.  Each party understands and acknowledges that the other party is not
         making any representation or warranty, express or implied, as to the
         accuracy or completeness of the Confidential Information, and the other
         party will not have any liability to such party or any other person
         resulting from the use by such party of the Confidential Information.

16.      NONSOLICITATION

     A.  During the term of this Agreement and for one (1) year thereafter, each
         party, directly or indirectly, will not solicit, hire or contact any
         employee of the other party for the purpose of hiring them or causing
         them to terminate their employment relationship with the other party.

     B.  Unless otherwise agreed to in writing by the parties hereto, in the
         event that a party hires an employee of the other party, the hiring
         party will pay a fee to the other party equal to thirty (30%) of the
         new hire's first year base salary, commission and bonus, payable
         monthly, beginning with the second month of the new hire's hire date
         with the hiring party. No other compensation or costs shall be paid by
         the hiring party to the other party.

                           should become vested under this option, and (ii) to
                           notify CyberGuard in the event, in accordance with
                           Marketlink's records, any of the individuals achieves

                           which would trigger vesting as described above.

                           books and records in connection with the option

                  of CyberGuard Common Stock as of the effective date of this
                  Agreement, which option shall vest only if: (1) CyberGuard
                  terminates this Agreement for cause due to Marketlink's
                  failure to achieve the minimum revenue commitments for the
                  first quarter or for the second quarter of this Agreement as
                  set forth in section 14 of Exhibit D of this Agreement, and

                  terminated earlier.

                  (g)      Effective on the date of termination of this
                  Agreement, the above-listed options shall terminate, but
                  Marketlink's right to exercise the vested shares under each
                  above-listed option shall survive for ninety (90) days from
                  the termination date of this Agreement.

                  (h)      Company and Marketlink agree to work together to
                  prepare and enter into stock option agreements for the

</TABLE>

         Marketlink and CyberGuard further agree that in the event Marketlink
         exceeds the revenue commitment for a prior quarter of this Agreement
         but fails to meet the revenue commitment for the following quarter
         during the first year of this Agreement, then the revenue amount
         achieved by Marketlink above the prior quarter's commitment ("Excess
         Revenue") shall be applied towards the commitment for the following
         quarter. (By way of example, if Marketlink achieves revenue of $400,000
         during the first quarter of this Agreement and $1,400,000 during the
         second quarter of this Agreement, then the $100,000 Excess Revenue
         achieved in the first quarter will be applied towards the second
         quarter commitment, thus Marketlink would then meet its $1,500,000
         revenue commitment.)

15.      Manage CyberGuard Resellers existing as of the effective date of this
         Agreement.

                           Marketlink and CyberGuard further agree that in the
                           event Marketlink exceeds the revenue commitment for a
                           prior quarter of this Agreement but fails to meet the
                           revenue commitment for the following quarter during
                           the first year of this Agreement, then the revenue
                           amount achieved by Marketlink above the prior
                           quarter's commitment ("Excess Revenue") shall be
                           applied towards the commitment for the following
                           quarter. (By way of example, if Marketlink achieves
                           revenue of $300,000 during the first quarter of this
                           Agreement and $950,000 during the second quarter of
                           this Agreement, then the $100,000 Excess Revenue
                           achieved in the first quarter will be applied towards
                           the second quarter commitment, thus Marketlink would
                           then meet its $1,050,000 revenue commitment.)"

         12.      The following Section 17 shall be inserted at the end of
                  Exhibit D of this Agreement:

                           "Assure that Marketlink's website displays during the
                           term of this Agreement CyberGuard Corporation as
                           Marketlink's firewall/VPN partner."

         13.      The following Section 1.G shall be inserted at the end of

                           Mississippi, Alabama and Tennessee."

         14.      The following Section 1.H shall be inserted at the end of

                           Offices."

         15.      Section 10.B (1) and (2) shall be deleted it in its entirety
                  and the following Section 10.B shall be substituted in its
                  place:

                           "No additional compensation of any kind shall be paid
                           to Marketlink, except that (1) in the event this
                           Agreement is terminated for cause within the first
                           six months from the effective date of the Agreement,
                           CyberGuard will pay to Marketlink the pro-rated
                           amount of the Base Compensation that was unpaid but
                           due and earned through the effective date of
                           termination of this Agreement, and (2) in the event
                           this Agreement is terminated for cause by CyberGuard
                           during the first twelve months from the effective
                           date hereof due to Marketlink's failure to achieve
                           the minimum revenue commitments set forth in Section
                           14 of Exhibit D hereof, then CyberGuard will pay to
                           Marketlink commission in the percentage(s) as set
                           forth in this Agreement for all Product sales in the

                           during the period of three months from the effective
                           date of termination of this Agreement, subject to
                           CyberGuard's unconditional right to chargeback
                           Marketlink for the commissions paid or credited to
                           Marketlink on all sales accepted by CyberGuard but

         16.      Capitalized terms not otherwise defined in this Amendment
                  shall have the meanings ascribed to such terms in the
                  Agreement.

         17.      All terms and conditions of the Agreement are hereby ratified
                  and shall remain in full force and effect except to the extent
