within twenty-four (24) months following the effective date of a Change in
Control, Executive (i) is terminated by the Company for any reason other than
Misconduct or Disability or (ii) terminates employment with the Company for Good
Reason, Executive shall receive the following benefits:

          (A) BASE SALARY. Executive shall receive an amount equal to 200% of

          (B) ANNUAL BONUS. Executive shall receive an amount equal to either
(i) 200% of Executive's target bonus under the Company's annual bonus program,

basis for Executive's termination of employment, 200% of Executive's target
bonus under such program immediately prior to its suspension or termination.

          (C) EXTENDED EXERCISABILITY OF OPTIONS. Executive shall be entitled to
exercise his or her outstanding stock options, to the extent such options are

("COBRA"), the Company shall pay the portion of premiums of Executive's group
medical, dental and vision coverage, including coverage for Executive's eligible
dependents, that the Company paid prior to Executive's termination of
employment, through the earlier of (i) the date on which Executive obtains

(24) months following the effective date of such termination, or (iii) the end
of the period during which COBRA coverage will be made available to Executive.
Executive shall be required to notify the Company immediately if Executive

     No provision of this Agreement shall affect the continuation coverage rules
under COBRA, except that the Company's payment of any applicable insurance
premiums shall be credited as a payment by Executive for purposes of Executive's
payment required under COBRA. Therefore, the period during which Executive may
elect to continue the Company's group medical coverage at Executive's own
expense under COBRA, the length of time during which COBRA coverage will be made
available to Executive, and all other rights and obligations of Executive under
COBRA (except the obligation to pay insurance premiums that the Company pays

rules would apply in the absence of this Agreement. At the conclusion of the
period during which the Company will pay a portion of the premiums for
Executive's group medical, dental and vision coverage, Executive shall be
responsible for the entire payment of premiums required under COBRA for the
duration of the COBRA period. For purposes of this Section 2.1 (d), applicable
premiums that will be paid by the Company shall not include any amounts payable

reimbursement plan, which amounts, if any, are the sole responsibility of
Executive.

          (I) In the event of a Change in Control described in any of clauses
(a) through (f) of section 1.3 of this Agreement, all outstanding stock options
held by Executive shall become immediately vested and exercisable effective upon
such Change in Control.

          (II) If, within twenty-four (24) months following the effective date
of a Change in Control described in clause (g) or (h) of section 1.3 of this
Agreement, Executive is (i) terminated by the Company for any reason other than
Misconduct or (ii) terminates employment with the Company for Good Reason, all
outstanding stock options held by Executive shall become immediately vested and
exercisable effective upon such termination.

     2.3 FLIGHT PRIVILEGES. Executive shall be entitled to top priority, first
class, positive space travel privileges, to be provided by AWA or, if AWA did
not survive the Change in Control, by the airline which survived the Change in
Control. The travel privileges would cover Executive and his/her dependents for
as long as Executive lives.

     2.4 MITIGATION. Except as otherwise specifically provided herein, Executive
shall not be required to mitigate damages or the amount of any payment provided
under this Agreement by seeking other employment or otherwise, nor shall the
amount of any payment provided for under this Agreement be reduced by any
compensation earned by Executive as a result of employment by another employer
received by Executive or by any retirement benefits received


                                       5.

any reason other than Misconduct or Disability, or (ii) by Executive for Good
Reason.

                                    ARTICLE 3

                     LIMITATIONS AND CONDITIONS ON BENEFITS

     3.1 RELEASE PRIOR TO PAYMENT OF BENEFITS. In order to be eligible to
receive benefits under this Agreement, Executive must execute a general waiver
and release in substantially the form attached hereto, as Exhibit A, Exhibit B
or Exhibit C, as appropriate, and such release must become effective in
accordance with its terms. The Company, in its sole discretion, shall determine
the form of the required release, which may be incorporated into a termination
agreement or other agreement with Executive, and may modify the form of the
required release to comply with applicable federal or state law.

     3.2 PARACHUTE PAYMENTS. If any payment, distribution or benefit Executive
would receive from the Company or otherwise, but determined without regard to
any additional payment required under this Section 3.2, pursuant to the terms of
this Agreement ("Payment"), would (i) constitute a "parachute payment" within
the meaning of Section 280G of the Internal Revenue Code of 1986, as amended
(the "Code"), and (ii) be subject to the excise tax imposed by Section 4999 of
the Code or any interest or penalties payable with respect to such excise tax
(such excise tax, together with any such interest and penalties, are hereinafter
collectively referred to as the "Excise Tax"), then Executive shall be entitled
to receive from the Company an additional payment (the "Gross-Up Payment") in an
amount that shall fund the payment by Executive of any Excise Tax on the Payment
as well as all income and employment taxes imposed on the Gross-Up Payment, any
Excise Tax imposed on the Gross-Up Payment and any interest or penalties imposed
with respect to income and employment taxes imposed on the Gross-Up Payment.

     The accounting firm engaged by the Company for general audit purposes as of
the day prior to the effective date of the Change in Control shall perform the
foregoing calculations. If the accounting firm so engaged by the Company is
serving as accountant or auditor for the individual, entity or group effecting
the Change in Control, the Company shall appoint a nationally recognized
accounting firm to make the determinations required hereunder. The Company shall
bear all expenses with respect to the determinations by such accounting firm
required to be made hereunder.

     The accounting firm engaged to make the determinations hereunder shall
provide its calculations, together with detailed supporting documentation, to
the Company and Executive within fifteen (15) calendar days after the date on
which Executive's right to a Payment is triggered (if requested at that time by
the Company or Executive) or such other time as requested by the Company or
Executive. If the accounting firm determines that no Excise Tax is payable with
respect to a Payment, either before or after the application of the Reduced
Amount, it shall furnish the Company and Executive with an opinion reasonably
acceptable to Executive that no Excise Tax will be imposed with respect to such
Payment. Any good faith determinations of the


                                       6.

<PAGE>

accounting firm made hereunder shall be final, binding and conclusive upon the
Company and Executive.

     3.3 CERTAIN REDUCTIONS AND OFFSETS. The Company, in its sole discretion,
shall have the authority to reduce Executive's severance benefits, in whole or
in part, by any other severance benefits, pay in lieu of notice, or other
similar benefits payable to Executive by the Company that become payable in
connection with Executive's termination of employment pursuant to (i) any
applicable legal requirement, including, without limitation, the Worker
Adjustment and Retraining Notification Act (the "WARN Act"), (ii) a written
employment or severance agreement with the Company, or (iii) any Company policy
or practice providing for Executive to remain on the payroll for a limited
period of time after being give notice of the termination of Executive's
employment. The benefits provided under this Agreement are intended to satisfy,
in whole or in part, any and all statutory obligations that may arise out of
Executive's termination of employment, and the Company shall so construe and
enforce the terms of this Agreement. The Company's decision to apply such
reductions to the severance benefits of one Executive and the amount of such
reductions shall in no way obligate the Company to apply the same reductions in
the same amounts to the severance benefits of any other Executive, even if
similarly situated. In the Company's sole discretion, such reductions may be
applied on a retroactive basis, with severance benefits previously paid being
recharacterized as payments pursuant to the Company's statutory obligation.

     3.4 TERMINATION ON ACCOUNT OF DEATH. In no event shall a termination on
account of Executive's death entitle Executive or any of his or her heirs or
beneficiaries to any benefits under this Agreement.

     3.5 TERMINATION OF BENEFITS. Benefits under this Agreement shall terminate
immediately if Executive, at any time, violates any proprietary information or
confidentiality obligation to the Company.

     3.6 TERMINATION OF CERTAIN OTHER BENEFITS. All other benefits (such as
401(k) plan coverage) shall terminate as of Executive's termination date.

     3.7 NON-DUPLICATION OF BENEFITS. Executive is not eligible to receive
benefits under this Agreement more than one time.

                                    ARTICLE 4

                       TIME OF PAYMENT AND FORM OF BENEFIT

     4.1 The Company reserves the right to determine in what form the severance
benefits under this Agreement shall be paid and to determine the timing of such
payments. All such payments under this Agreement shall be subject to applicable
withholding for federal, state, and local taxes. In no event shall payment of
any severance benefit under Section 2.1 of this Agreement be made prior to
Executive's termination date or prior to the effective date of the release
described in Section 3.1 of this Agreement.

unenforceable in any respect under any applicable law or rule in any
jurisdiction, such invalidity, illegality or unenforceability will not affect
any other provision or any other jurisdiction, but this Agreement will be
reformed, construed and enforced in such jurisdiction as if such invalid,
illegal or unenforceable provisions had never been contained herein.

     5.4 WAIVER. If any party should waive any breach of any provisions of this
Agreement, the party shall not thereby be deemed to have waived any preceding or
succeeding breach of the same or any other provision of this Agreement.

     5.5 COMPLETE AGREEMENT. This Agreement, including Exhibit A, Exhibit B and
Exhibit C, constitutes the entire agreement between Executive and the Company
and is the complete, final, and exclusive embodiment of their agreement with

surviving entity resulting from a Change in Control and upon any other person
who is a successor by merger, acquisition, consolidation or otherwise to the
business formerly carried on by the Company, and their respective successors,

withheld unreasonably.

     I acknowledge that I have read and understand Section 1542 of the
California Civil Code which reads as follows: "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 MUST HAVE MATERIALLY
AFFECTED HIS SETTLEMENT WITH THE DEBTOR." I hereby expressly waive and
relinquish all rights and benefits under that section and any law of any
jurisdiction of similar effect with respect to my release of any claims I may
have against the Company.

     Except as otherwise set forth in this Release, I hereby release, acquit and
forever discharge the Company, its parents, subsidiaries and affiliates, and
their officers, directors, agents, servants, employees, shareholders,
successors, assigns and affiliates, of and from any and all claims, liabilities,
demands, causes of action, costs, expenses, attorneys' fees, damages,
indemnities and obligations of every kind and nature, in law, equity, or
otherwise, known and unknown, suspected and unsuspected, disclosed and
undisclosed (other than any claim for indemnification I may have as a result of
any third party action against me based on my employment with the Company),
arising out of or in any way related to agreements, events, acts or conduct at
any time prior to and including the date I execute this Release, including, but
not limited to: all such claims and demands directly or indirectly arising out
of or in any way connected with my employment with the Company or the
termination of that employment, including but not limited to, claims of
intentional and negligent infliction of emotional distress, any and all tort
claims for personal injury, claims or demands related to salary, bonuses,
commissions, stock, stock options, or any other equity or ownership interests in
the Company, vacation pay, fringe benefits, expense reimbursements, severance
pay, or any other form of equity or compensation; claims pursuant to any
federal, state or local law or cause of action including, but not limited to,
the federal Civil Rights Act of 1964, as amended; the federal Age Discrimination
in Employment Act of 1967, as amended ("ADEA"); the federal Employee Retirement
Income Security Act of 1974, as amended; the federal Americans with Disabilities
Act of 1990; the Arizona Civil Rights Act, as amended; tort law; contract law;
wrongful discharge; discrimination; fraud; defamation; emotional distress; and
breach of the implied covenant of good faith and fair dealing.

     I acknowledge that I am knowingly and voluntarily waiving and releasing any
rights I may have under ADEA and that the consideration given under the
Agreement for the waiver and release in the preceding paragraph hereof is in
addition to anything of value to which I was already entitled. I further
acknowledge that I have been advised by this writing, as required by the ADEA,
that: (A) my waiver and release do not apply to any rights or claims that may
arise on or after the date I execute this Release; (B) I have the right to
consult with an attorney prior to executing this Release; (C) I have twenty-one
(21) days to consider this Release (although I may
