Exhibit 10.02

June 4, 2004

Kenneth B. Arola
198 Alden Lane
Livermore, CA 94550

Dear Ken:

        We regret to notify you that your position has been eliminated due to a
reorganization of Adaptec's business. Between today and August 2, 2004, your
focus is to transition work duties and participate in an exit meeting with your
manager and exit interview with your human resources consultant. Between
August 3 and September 6 you will be on vacation status (192 hours). You will
remain on Adaptec's payroll and continue to receive payroll checks through your
termination date, November 5, 2004. Your final payroll check will include any
unused accrued vacation, sabbatical payout, if eligible, and a refund of any
unused amounts that have been deducted from your earnings for purposes of
participating in Adaptec's Employee Stock Purchase Plan.

        We find these circumstances unfortunate and wish to offer you certain
severance benefits so you can pursue other opportunities outside of Adaptec. You
are eligible for outplacement benefits, which are outlined in your packet.

        Please sign and return the Separation Agreement and General Release
along with the exit paperwork to Adaptec Human Resources in the enclosed
envelope no later than August 2, 2004.

SEPARATION AGREEMENT AND GENERAL RELEASE

1.Adaptec's Consideration for Agreement: In exchange for the release and
agreements described herein, Adaptec agrees as follows:

a)Provided that you have returned all Adaptec property, equipment, and assets,
your severance payment will be processed in two payments: the first payable
November 12, 2004, equal to 2 months of your regular base pay less legally
mandated payroll deductions and withholdings. On January 7, 2005 you will
receive a second payment, which will be equal to 4 months of your regular base
pay plus an additional $20,000 payment (gross) less legally mandated payroll
deductions and withholdings. These payments are being given as consideration for
this Agreement and are not otherwise due.

b)You also acknowledge that Adaptec stock option grants that have vested as of
the termination date must be exercised within three (3) months of termination.
However, stock options granted from plans assumed through acquisitions may vary.

c)Beginning on December 1, 2004, you shall be entitled to continuation of your
Adaptec health, vision and dental benefits pursuant to the Consolidated Omnibus
Budget and Reconciliation Act ("COBRA"). You must submit completed COBRA
Qualifying Event Notification enrollment forms directly to Ceridian for
coverage. Adaptec agrees to pay the premiums for those COBRA benefits through
and until May 31, 2005, at which time said benefits shall cease unless you elect
to pay for those benefits.

2.Consideration for Agreement: In consideration for the payments and
undertakings described above, you individually and on behalf of your
representatives, successors, and assigns, do hereby completely release and
forever discharge Adaptec, its shareholders, employees, owners, officers and
directors, Board Members, and all other representatives, agents, entities,
subsidiaries, divisions, directors, attorneys, successors, and assigns from all
claims, rights, demands, actions, obligations, and causes of action of any and
every kind, nature and character, known or unknown, which you

may now have, or have ever had, against them arising from or in any way
connected with the employment relationship between the parties, any actions
during the relationship or the termination thereof. This Release covers all
statutory, common law, constitutional and other claims, including but not
limited to: all "wrongful discharge" and "constructive discharge" claims; all

3.Wavier of Unknown Future Claims: You have read Section 1542 of the Civil Code
of the State of California, which provides as follows:

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

You acknowledge that Section 1542 gives you the right not to release existing
claims, of which you are not now aware, unless you voluntarily choose to waive
this right. Having been so apprised, you hereby voluntarily waive the rights
described in Section 1542, and elect to assume all risks for claims that now

Agreement.

conditions of this Agreement, including any and all references to any alleged
underlying claims, are strictly confidential. You shall not disclose, discuss or
reveal the existence or the terms of this Agreement to any persons, entities or
organizations except to your spouse, attorney, financial advisor, or as required

5.Savings Clause: Should any of the provisions of this Agreement be determined
to be invalid by a court or government agency of competent jurisdiction, it is
agreed that such determination shall not affect the enforceability of the other
provisions herein. California law shall govern the validity and interpretation
of this Agreement.

6.Preparation of Agreement: Regardless of which party initially drafted this
Agreement, it shall not be construed against any one party, and shall be
construed and enforced as a mutually prepared Agreement.

7.Mandatory Arbitration Clause: You and Adaptec agree that any action to enforce
the terms and conditions of this Agreement or for the breach of this Agreement,
shall be referred to final and binding arbitration. Any arbitration proceeding

Association and the Federal Arbitration Act and the parties hereto expressly
waive their rights, if any, to have any such matters heard by a court or jury,
or administrative agency whether federal or state. The prevailing party in any
