5.                                    PHANTOM STOCK UNIT ACCOUNT

5.1       Establishment of Phantom Stock Unit Account.  The Company shall establish a Phantom Stock Unit Account with respect to Deferred Compensation for each Participant.  The establishment of a Phantom Stock Unit Account constitutes only a method, by bookkeeping entry, of determining the amount of deferred benefits to be distributed under the Plan.  The Company shall be under no obligation to acquire or hold any Stock or any other securities or specific assets by reason of the credits made to the Phantom Stock Unit Accounts hereunder.

5.2       Unsecured Creditors; Unfunded Plan.  A Participant’s or Beneficiary’s rights to receive distributions under this Plan are those of an unsecured general creditor of the Company.  Such rights constitute a promise by the Company to make distributions to Participants and their Beneficiaries in the future.  All amounts under the Plan, including a Participant’s Phantom Stock Unit Account, shall remain (until paid to the Participant or Beneficiary) the property of the Company and shall be subject to the claims of the Company’s creditors in the event of the Company’s bankruptcy or insolvency.  The Plan shall be unfunded for federal tax purposes.  The obligation of the Company may, in its sole discretion, be satisfied from any source of funds, inclu ding, but not limited to, payment from a trust or trusts established by the Company which permit such payments to be made therefrom; provided, however, that such trust or trusts constitute unfunded arrangements subject to the claims of the Company’s creditors in the event of its bankruptcy or insolvency.  No Participant or Beneficiary shall have any secured or beneficial interest in any property, rights or investments held by the Company, whether or not held in connection with the Plan, including but not limited to any assets held in any trust established by the Company in connection with the Plan.

5.3       Timing of Credits.  A Participant’s Deferred Compensation shall be credited to a Phantom Stock Unit Account as soon as practicable following the time at which such amounts would have been paid or transferred to the Participant in the absence of an Election; provided, however, that one-fourth (¼) of the full amount elected to be deferred from a Participant’s Annual Retainer for a Plan Year and/or all of the Chair and Committee Fees payable for the applicable calendar quarter shall be credited to the Phantom Stock Unit Account on the last day

7.

of each calendar quarter on which Stock is traded on the New York Stock Exchange, except that no such amount shall be credited for any quarter of the Plan Year that begins after the Participant has ceased service as a Non-Employee Director.  A Participant’s foregone Restricted Stock Award shall be credited to a Phantom Stock Unit Account as of the date on which such Restricted Stock Award would have been awarded to the Participant in the absence of an Election to forego such Restricted Stock Award.

5.4       Amount of Credits; Vesting.  Deferred Compensation (excluding foregone Restricted Stock Award(s) credited to a Phantom Stock Unit Account) shall be converted into Phantom Stock Units, the number of which shall be equal to such Deferred Compensation to be credited to the Phantom Stock Unit Account divided by the Market Value of a share of Stock on the date of such credit, and such Phantom Stock Units shall be fully vested and nonforfeitable at all times.  The number of Phantom Stock Units to be credited as Deferred Compensation by reason of an election to forego a Restricted Stock Award shall be equal to the number of shares of Stock subject to the foregone Restricted Stock Award, and such Phantom Stock Units shall be subject to the same vesting and forfeiture restrictions to which the foregone Restricted Stock Award would have been subject.  Phantom Stock Units subject to vesting or forfeiture restrictions are referred to in this Plan as “Restricted Units,” and fully vested and nonforfeitable Phantom Stock Units are referred to in this Plan as “Nonrestricted Units.”  Phantom Stock Unit Accounts shall be adjusted on account of dividends, cash distributions, stock splits and similar events as follows:

(a)        As of the date when any cash dividend or other cash distribution is payable with respect to the Stock, there shall be credited to the Phantom Stock Unit Account an amount equal to the value which would have been payable with respect to shares of Stock equal in number to the number of Phantom Stock Units then credited to the Phantom Stock Unit Account.  Such amount shall then be converted into a number of Phantom Stock Units based upon the amount to be credited divided by the Market Value of a share of Stock on the date of the credit.  All Phantom Stock Units credited under this Section 5.4(a) shall be Nonrestricted Units, without regard to whether the Phantom Stock Units from which they are derived are Restricted Units or Nonrestricted Units.

(b)        In the event of any change in the number of shares of outstanding Stock by reason of any stock split, stock dividend, recapitalization, or the like, whereby the outstanding shares of Stock are adjusted, the number of Phantom Stock Units credited to the Phantom Stock Unit Account shall be equitably adjusted to reflect such change.  Any adjustments provided in this Section 5.4(b) with respect to Nonrestricted Units shall be in the form of Nonrestricted Units.  Any adjustments provided in this Section 5.4(b) with respect to Restricted Units shall be in the form of Restricted Units, which shall be subject to the same vesting and forfeiture terms and conditions applicable to the original Restricted Units from which they are derived.

5.5       Restricted Units.

(a)        Restricted Units shall be subject to the terms and conditions set forth in Section 5.5(b) until the end of the specified restricted period applicable to such Restricted Units

8.

(the “Restricted Period”).  Restricted Units not previously forfeited shall vest and become nonforfeitable during the applicable Restricted Period and shall thereafter be Nonrestricted Units.

(b)        The “Vesting Commencement Date” for Restricted Units credited to a Participant’s Phantom Stock Unit Account in respect of a foregone Restricted Stock Award shall be the date on which such Restricted Stock Award would have been received by the Participant in the absence of an Election to forego such Restricted Stock Award.  The Restricted Period for such Restricted Units credited to a Participant’s Phantom Stock Unit Account shall be determined by the Company and communicated to the Participant in advance of the time the Participant must make his or her Election for a Plan Year.

(c)        Any applicable Restricted Period shall terminate and any Phantom Stock Units that are then Restricted Units shall immediately become Nonrestricted Units as of the date any of the following occurs: (i) a Change of Control occurs; (ii) the Participant’s service with the Company ceases due to the Participant’s death or Disability; (iii) the Participant is removed by the Company’s stockholders as a member of the Board or fails to be reelected by the Company’s stockholders as a member of the Board, in either case without Cause; or (iv) the Participant fails to be nominated for reelection to the Board without Cause.  If a Participant’s service with the Company ceases for any reason other than as set forth in the preceding sentence, then an y Phantom Stock Units that are then Restricted Units shall be forfeited, and all rights of the Participant to receive any benefits under the Plan attributable to such forfeited Restricted Units shall terminate.

6.                                    DISTRIBUTION OF PLAN BENEFITS

6.1       Form of Benefit.  All benefits paid under this Plan shall be paid in a single sum in the form of whole shares of Stock under the Incentive Plan, with any fractional shares of Stock being paid in a single sum in the form of cash based on the Market Value of a share of Stock on the date of the payment.  The portion of such shares paid in respect of any deferred Annual Retainer, Chair and Committee Fees and Tax Gross-Up Payment shall be paid pursuant to Section 6.5 of the Incentive Plan and the portion of such shares paid in respect of any foregone Restricted Stock Award shall be paid pursuant to Section 6.6 of the Incentive Plan.

6.2       Distribution Elections.

(a)        At the time of each Election pursuant to Sections 4.1, 4.2 or 4.3 to defer receipt of Compensation, forego receipt of a Restricted Stock Award or defer receipt of a Tax Gross-Up Payment, a Participant also shall elect, on such form as the Company prescribes, the date of distribution of the portion of his or her Phantom Stock Unit Account attributable to the amount of Deferred Compensation specified in such Election; provided, however, that if the Participant elects to forego receipt of a Restricted Stock Award pursuant to such Election, the Participant must elect a date of distribution for the entire portion of his or her Phantom Stock Unit Account attributable to the amount of Deferred Compensation specified in such Election that is on or after the end of the applicable Rest ricted Period for the foregone Restricted Stock Award.

9.

(b)        A Participant may change his or her distribution election in accordance with procedures determined by the Company, provided, however, that:

(i)         With respect to Section 409A Grandfathered Amounts, any changed election shall not be effective unless a full calendar year passes between the calendar year in which such changed election is submitted and the calendar year in which the distribution date designated in such change election occurs; and

(ii)        With respect to Section 409A Non-Grandfathered Amounts, any changed election (A) shall not take effect until at least twelve (12) months after the date on which the change is made, (B) must be made more than twelve (12) months prior to the date distribution otherwise would have been made and (C) must designate a new date for distribution that is at least five (5) years following the date distribution otherwise would have been made.

(c)        No elections under this Section 6.2 may be made or changed as to distributions from a Participant’s Phantom Stock Unit Account unless the Board has approved in advance such election or change of election in a manner, if any, that satisfies the requirements for exemption of Phantom Stock Unit Account transactions pursuant to Rule 16b-3 promulgated under the Exchange Act.

6.3       Termination of Service on the Board or Change of Control.  As soon as administratively practicable following the termination of a Participant’s service on the Board, and notwithstanding any election that the Participant has made under the Plan pursuant to Section 6.2, the Company shall pay to such Participant or to the Participant’s Beneficiary in a lump sum all amounts then credited to the Participant’s Phantom Stock Unit Account as Nonrestricted Units (including formerly Restricted Units which become Nonrestricted Units on account of such termination in accordance with Section 5.5(c)), and any Restricted Units shall be forfeited; provided, however, that with respect to Section 409A Non-Grandfathered Amounts, if a Change of Control occurs prior to any such elected date of distribution pursuant to Section 6.2 or termination of service, payment of such amounts shall be made in a lump sum as soon as administratively feasible after the effective date of the Change of Control, provided that the Change of Control constitutes a change in the ownership or effective control of the Company, or in the ownership of a substantial portion of the assets of the Company, as determined in accordance with Section 1.409A-3(i)(5) of the Treasury Regulations.

6.4       Early Distribution of Section 409A Grandfathered Amounts.  A Participant may elect to receive a distribution of all or any portion of the amount of Section 409A Grandfathered Amounts then credited to the Participant’s Phantom Stock Unit Account as Nonrestricted Units on a date prior to that established under the Plan, including the Participant’s distribution election under Section 6.2; provided, however, that (i) the amount distributed shall be equal to ninety percent (90%) of the amount elected by the Participant, and (ii) the remaining ten percent (10%) of the amount elected by the Participant shall be treated as forfeited by the Participant.  A Participant may not receive any early distributions of any Section 409A Non-Grandfather ed Amounts pursuant to this Section 6.4.

10.

6.5       Unforeseeable Emergency.  Upon application by a Participant, the Company may direct the distribution in a lump sum of all or a portion of the remaining amount credited to the Participant’s Phantom Stock Unit Account as Nonrestricted Units in the event of an Unforeseeable Emergency.  Any such application must set forth the circumstances constituting such Unforeseeable Emergency.  The determination as to whether an Unforeseeable Emergency exists and as to the amount distributable under the Plan as a result of such Unforeseeable Emergency shall be made by the Company in its sole discretion.

For purposes of the Plan, an “Unforeseeable Emergency” shall mean any severe financial hardship to the Participant resulting from (i) a sudden and unexpected illness or accident of the Participant or a dependent (as defined in Section 152(a) of the Code) of the Participant, (ii) loss of the Participant’s property due to casualty, or (iii) other similar extraordinary and unforeseen circumstances arising as a result of events beyond the control of the Participant.  Any distribution pursuant to this provision is limited to the amount necessary to meet the Unforeseeable Emergency, and any amounts necessary to pay any federal, state or local income taxes or penalties reasonably anticipated to result from such distribution.  The distribution may not exceed the then vested portion of the Participant’s Account.  The circumst ances that will constitute an Unforeseeable Emergency will depend upon the facts of each case, but, in any case, payment may not be made to the extent that such emergency is or may be relieved (i) through reimbursement or compensation by insurance or otherwise; (ii) by liquidation of the Participant’s assets, to the extent the liquidation of such assets would not itself cause severe financial hardship; or (iii) by cessation of deferrals under the Plan.  Furthermore, examples of events that would not be considered Unforeseeable Emergencies include the need to send a Participant’s child to college or the desire to purchase a home.

6.6       No Assignment or Alienation.  The right to receive a distribution under this Plan shall not be subject to anticipation, alienation, sale, assignment, pledge, encumbrance or charge, and any attempt to anticipate, alienate, sell, assign, pledge, encumber, or charge such right shall be void.  No distribution or right to distribution shall in any manner be liable for or subject to debts, contracts, liabilities or torts of the Participant or the Participant’s Beneficiary.

A request for review must set forth all of the grounds on which it is based, all facts in support of the request and any other matters that the applicant feels are pertinent.  The applicant (or his or her representative) shall have the opportunity to submit (or the Company may require the applicant to submit) written comments, documents, records, and other information relating to his or her claim.  The applicant (or his or her representative) shall be provided, upon request and free of charge, reasonable access to, and copies of, all documents, records and other information relevant to his or her claim.  The review shall take into account all comments, documents, records and other information submitted by the applicant (or his or her representative) relating to the claim, without regard to whether such information was submitted or considered in the initial benefit determination .

(d)        Decision on Review.  The Company will act on each request for review within sixty (60) days after receipt of the request, unless special circumstances require an extension of time (not to exceed an additional sixty (60) days), for processing the request for a review.  If an extension for review is required, written notice of the extension will be furnished to the applicant within the initial sixty (60) day period.  This notice of extension will describe the special circumstances necessitating the additional time and the date by which the Company is to render its decision on the review.  The Company will give prompt, written or electronic notice of its decision to the applicant.  In the event that the Company confirms the denial of the applicatio n for benefits in whole or in part, the notice will set forth, in a manner calculated to be understood by the applicant, the following:

(i)         the specific reason or reasons for the denial;

(ii)        references to the specific Plan provisions upon which the denial is based; and

(iii)       a statement that the applicant is entitled to receive, upon request and free of charge, reasonable access to, and copies of, all documents, records and other information relevant to his or her claim.

(e)        Rules and Procedures.  The Company will establish rules and procedures, consistent with the Plan, as necessary and appropriate in carrying out its responsibilities in reviewing benefit claims.  The Company may require an applicant who wishes to submit additional information in connection with an appeal from the denial of benefits to do so at the applicant’s own expense.

(f)        Exhaustion of Remedies.  No legal action for benefits under the Plan may be brought until the claimant (i) has submitted a written application for benefits in accordance with the procedures described by Section 7.3(a) above, (ii) has been notified by the Company

13.

that the application is denied, (iii) has filed a written request for a review of the application in accordance with the appeal procedure described in Section 7.3(c) above, and (iv) has been notified that the Company has denied the appeal.  Notwithstanding the foregoing, if the Company does not respond to a Participant’s claim or appeal within the relevant time limits specified in this Section 7.3, the Participant may bring legal action for benefits under the Plan.

8.                                    BENEFICIARY DESIGNATION

Each Participant shall have the right, at any time, to designate any person or persons as Beneficiary or Beneficiaries (both primary as well as contingent) to whom distributions under this Plan shall be made in the event of the Participant’s death prior to complete distribution to the Participant of the benefits due the Participant under the Plan.  Each Beneficiary designation shall become effective only when filed in writing with the Company during the Participant’s lifetime on a form prescribed by the Company.  The filing of a new Beneficiary designation form will cancel all Beneficiary designations previously filed.  The spouse of a married Participant domiciled in a community property jurisdiction shall join in any designation of Beneficiary or Beneficiaries other than the spouse.  If a Participant fails to designate a Beneficiary as provided above, or if all designated Beneficiaries predecease the Participant or die prior to complete distribution of the Participant’s benefits, then the Company shall direct the distribution of such benefits to the Participant’s estate.

9.                                    MISCELLANEOUS

9.1       Effective Date; Amendment and Termination.  This Plan shall be effective January 1, 2002, with continuation thereafter contemplated, subject to review of its operation.  However, this Plan shall at all times remain subject to amendment, modification or termination by action of the Company or the Board; provided, however, in the event of termination of the Plan, any Nonrestricted Units held in a Participant’s Phantom Stock Unit Account shall be distributed to the Participant in accordance with Section 6 hereof, and any Restricted Units shall continue to vest in accordance with the terms of their vesting schedules and, upon becoming Nonrestricted Units, shall be distributed to the Participant in accordance with Section 6 hereof.

9.2       No Employment or Service Rights.  This Plan shall not be deemed to constitute a contract of employment or service between the Company and any Participant.  Nothing contained in this Plan shall be deemed to give any Participant the right to be retained in the service of the Company or to interfere with the right of the Company or the Board to discharge any Participant at any time regardless of the effect which such discharge shall have upon such individual as a Participant in the Plan.

9.3       Arbitration.  All disputes, claims, or causes of action arising from or relating to this Plan shall be resolved to the fullest extent permitted by law by final, binding and confidential arbitration, by a single arbitrator, in Los Angeles, California, conducted by JAMS under the then applicable JAMS rules.  All Participants and the Company shall be deemed to have waived the right to resolve any such dispute through a trial by jury or judge or administrative proceeding.  The arbitrator shall: (a) have the authority to compel adequate

14.

discovery for the resolution of the dispute and to award such relief as would otherwise be permitted by law; and (b) issue a written arbitration decision, to include the arbitrator’s essential findings and conclusions and a statement of the award.  The arbitrator shall be authorized to award any or all remedies that the parties would be entitled to seek in a court of law.  The Company shall pay all JAMS’ arbitration fees in excess of the amount of court fees that would be required if the dispute were decided in a court of law.  Nothing in this Plan is intended to prevent either the Company or a Participant from obtaining injunctive relief in court to prevent irreparable harm pending the conclusion of any such arbitration.

9.4       Governing Law.  This Plan shall be construed in accordance with and governed by the laws of the State of California.

9.5       Severability.  In the event any provision of this Plan is held invalid, void or unenforceable, the same shall not affect, in any respect whatsoever, the validity of any other provisions of this Plan.

9.7       Successors.  This Plan shall be binding upon the Company and its successors and assigns.
