understood and agreed that this Agreement, and any exports, sales, transfers, or
any other disposition of CyberGuard Products or IRE/SafeNet Products, to the
extent incorporated in the Product, are subject to the laws and regulations of
the United States. Specifically, contracts and orders placed for the Product may
require advance U.S. Government Export approval or licensing, and, therefore all
such contracts and orders are subject to the receipt of any necessary approvals
and licenses. The parties hereto agree to solicit orders, and IRE agrees to
process and ship orders, in accordance with all applicable laws and regulations.

such maintenance in all other instances. Each party hereto agrees to maintain
support services sufficient to discharge the duty set forth in the preceding

directly or indirectly, for itself or for any other person, firm, corporation,
partnership, association or other entity, attempt to employ, employ or enter
into any contractual arrangement with any employee or former employee of the

or former employee has not been employed by the other party, its subsidiaries or
its predecessors in interest, for a period in excess of six months.

that a party hereto (the "Disclosing Party") is advised by counsel that public
disclosure relating to the Project or the other party is required, the

9.6  Disputes.

     9.6.1 Any controversy or claim related to or arising out of this Agreement
shall be settled by binding arbitration conducted under the Commercial
Arbitration Rules of the American Arbitration Association. Judgment on the
arbitrator's award may be entered and enforced in any court of competent
jurisdiction. Neither party will be precluded from seeking provisional remedies
in the courts including, but not limited to, temporary restraining orders and
preliminary injunctions, to protect its rights and interests, but such relief
will not be sought as a means to avoid or stay arbitration.

     9.6.2 This Section 9.6 provides the sole recourse for the settlement of any
dispute arising under or in connection with this Agreement. In any arbitration
between the parties, the prevailing party shall be entitled to reasonable
attorneys' fees and all costs of proceedings incurred in enforcing this
Agreement in addition to any other amount of recovery ordered in such
arbitration.

     9.6.3 IRE and CyberGuard each agree that if either of them determine to
begin an arbitration action, then such action may be brought only in the city or
county in which the corporate headquarters of the defendant to such action is
located, and each agree that venue is proper in such location.

9.7 Relationship of the Parties. The parties hereto agree that no
agency, employment, partnership, joint venture or franchise relationship is
created or shall be deemed to be created hereunder. Neither party shall have,
and neither shall represent to have, any power, right or authority to bind the
other or to assume or create any obligation or responsibility, express or
implied, on behalf of the other party or in the other party's name, except as
herein expressly permitted.

9.8 Entire Agreement. This Agreement constitutes the entire agreement
and supersedes any prior agreements or understandings between the parties hereto
regarding the subject matter hereof, and no amendment, alteration or waiver of
this Agreement shall be valid or binding unless made in writing and signed by
both parties.

agreement or agreements providing for CyberGuard's ability to resell the IRE
SafeNet family of products and for IRE's ability to resell the CyberGuard
Firewall family of products, now or hereafter developed during the term of this
Agreement.

9.11 Severability. Any provision in this Agreement found to be void,
voidable or unenforceable shall not affect the validity or enforceability of any
other provision in this Agreement. In the event that any provision of this
Agreement shall be declared void, voidable or unenforceable by a court of
competent jurisdiction, said provision shall be deemed to be amended to provide
the party seeking to enforce this Agreement the greatest protection available
under law.
