                                   ("RELEASE")

   _____________ ("Participant") has been awarded certain benefits pursuant to
the Sniffer Bonus Plan and the Sniffer Bonus Plan Participation Agreement signed
by Participant on __________, 2003, in connection with Participant's employment
with Networks Associates, Inc. (the "Company"), a Delaware corporation. For
purposes of this Release, the term "the Company" shall mean NAI and its
subsidiaries and affiliates.

   1. Participant's employment relationship with the Company is ended effective
_____________________ (the "Effective Date"). Participant understands that if
and only if he/she signs and returns this Release and complies with the terms of
the Sniffer Bonus Plan and the Sniffer Bonus Plan Participation Agreement,
Participant will receive the benefits described in Section 4 of the Sniffer

   2. In exchange for the benefits described in Section 4 of the Sniffer Bonus
Plan, Participant (on his own behalf and on behalf of Participant's successors
and assigns) hereby releases the Company and the officers, directors, employees,
stockholders, agents, and legal successors and assigns of the Company ("Released
Parties") from all claims, actions and causes of action, whether now known or
unknown, which he now has, or at any other time had, or shall or may have
against the Released Parties based upon, relating to or arising out of any
matter, cause, fact, thing, act or omission whatsoever occurring at any time up
to and including the Effective Date (as defined herein), including, but not
limited to, any claims for breach of express or implied contract, wages or
benefits owed, covenants of fair dealing and good faith, interference with
contract, option grants, wrongful discharge or termination, fraud, defamation,
negligence, assault, battery, invasion of privacy, false imprisonment, civil
conspiracy, duress, promissory or equitable estoppel, violation of public
policy, retaliation, personal injury, breach of fiduciary duty, bad faith,
infliction of emotional distress and employment discrimination or harassment of

   3. Participant acknowledges that he has read section 1542 of the Civil Code
of the State of California which, in its entirety, states:

         A general release does not extend to claims, which the creditor does
         not know or suspect to exist in his favor at the time of executing the
         release, which if known by him/her must have materially affected his
         settlement with the debtor.

SNIFFER BONUS PLAN - ANNEX 1 PAGE 1

<PAGE>

         Participant waives any rights that he/she has or may have under such
section 1542 to the fullest extent that Participant may lawfully waive such
rights pertaining to this Release. If Participant is employed by the Company in
a state other than California, Participant hereby waives any right or benefit
which he/she has under the other state's statutes similar to section 1542 of the
Civil Code of the State of California to the fullest extent that he/she may
lawfully waive such rights pertaining to this Release.

         4. Participant acknowledges and agrees that he will not make any
disparaging statements or otherwise say anything detrimental to any other person
or entity about the Company or its products, services or employees or take any
action detrimental to the Company.

         5. Participant agrees not to sue for any reason in any suit or
proceeding against the Company and/or its officers, directors, agents and
employees relating to the Released Matters. To the fullest extent permitted by
law, Participant agrees that he will not bring any charge or complaint with the
Texas Commission on Human Rights, the California Department of Fair Employment
and Housing, the U.S. Department of Labor, or any other administrative,
regulatory, legislative or judicial body based on or relating to in any way the
Released Matters. Participant further agrees that he will not, at any time in
the future, discuss, encourage or voluntarily assist or cooperate in the
prosecution of claims, demands or actions against any of the Parties Released by
him except as may be required by law. Participant will not directly or
indirectly suggest to anyone that he is aware of any claims or potential claims
or basis for any potential claims against the Company or any of its current and
former officers, directors, employees and agents. This provision shall not
prevent Participant from responding truthfully to a subpoena or other process as
compelled by law. In the event any charge, complaint, grievance, arbitration,
action or other proceeding was or is filed by Participant or on his behalf
(other than to receive the consideration described herein), he agrees not to
obtain or accept recovery or relief therefrom.

         6. Participant agrees to cooperate in the transition of his duties at
the Company and further agrees to provide reasonable assistance to the Company
should his knowledge or testimony be deemed useful by counsel for the Company in
pursuing or defending any pending or future legal claims involving the Company.
Examples of such assistance include speaking with individuals at the Company or
its outside counsel, assisting in locating documents or other evidence and
providing truthful testimony. The Company and Participant will attempt to
schedule such transition and assistance activities to occur at mutually
convenient times.

         7. Participant acknowledges that he has continuing obligations under
any confidentiality and assignment of inventions agreement Participant may have
signed in favor of the Company or under applicable law, which obligations will
not be affected or impaired in any way by this Release.

herein, Participant agrees:

                  a. that he will keep the terms of and sums paid under the

         the Sniffer Bonus Plan and this Release or any discussions between
         himself and the Company related to the Sniffer Bonus Plan and this
         Release or the circumstances regarding the separation of his employment
         with NAI. Participant agrees that he will maintain confidentiality of
         the terms and conditions of the Plan, except as required by law. If the
         Participant believes that a disclosure of the terms and conditions of
         the Plan is reasonably necessary for tax, accounting or financial
         purposes, Participant will request the Company's consent to the
         disclosure and obtain the Company's written consent before any
         disclosure is made. Any disclosure by Participant of the terms and
         conditions of the Plan without the Company's written consent shall be
         deemed a disclosure by Participant in violation of the Plan.

                  b. that if he fail to comply with any of the provisions of
         this Section 8, the Company shall be entitled, upon application to any
         court of competent jurisdiction, to specific performance or injunction
         or other relief in order to enforce or prevent violation of such
         provision or provisions. Nothing herein contained shall be construed as
         prohibiting the Company from pursuing any other remedies available to
         it for such breach or threatened breach, including the recovery of
         damages from Participant.

         9. Participant acknowledges that as a condition of receiving the
payments described in Section 4 of the Sniffer Bonus Plan, he has returned to
the Company on or before the Effective Date, all Company property in his
possession, including but not limited to, software, equipment, documents, sales
materials, or other company records, parking cards, pass cards, access cards,
keys, calling cards, mobile phones, beepers, pagers, credit cards, computers,
fax machines, copy machines, personal digital assistants or any other equipment.

         10. Participant agrees that this Release embodies the entire
understanding between the Company and him and that this Release may not be
modified or amended unless such modification or amendment is in writing and is
signed by Participant and by an authorized officer of the Company.

         11. Participant agrees that neither this Release nor the furnishing of
the consideration for this Release shall be deemed or construed at any time, for
any purpose, an admission by the Company of any liability or unlawful conduct of
any kind.

         12. Participant agrees that this Release shall not be assigned, pledged
or transferred in any way without the prior written consent of the Company.

         13. Should any provision of this Release be declared illegal or
unenforceable by any court of competent jurisdiction and cannot be modified to
be enforceable, excluding the general release language, such provision shall
immediately become null and void, leaving the remainder of this Release in full
force and effect. However, if any portion of the general release language were
ruled to be unenforceable for any reason, Participant agrees to return the
consideration paid hereunder to the Company.

         provisions which have been previously approved by Required Banks, and

         of default) which have not been previously approved by Required Banks,
         and (b) Debt of Borrower resulting from the issue of Borrower's senior
         subordinated unsecured notes in an aggregate outstanding principal
         balance of not greater than $150,000,000 (the "New Issuance"), and
