                  EXECUTIVE NONQUALIFIED STOCK OPTION AGREEMENT

NONQUALIFIED STOCK         This option is not intended to be an incentive stock
OPTION                     option under Section 422 of the Internal Revenue
                           Code, and it will be interpreted accordingly.

VESTING                    This option is only exercisable before it expires and
                           then only with respect to the vested portion of the
                           option. Subject to the preceding sentence, you may
                           exercise this option, in whole or in part, to
                           purchase a whole number of vested shares not less
                           than 100 shares, unless the number of shares
                           purchased is the total number available for purchase
                           under the option, by following the procedures set
                           forth in the Plan and below in this Agreement.

                           Your right to purchase shares of Stock under this
                           option vests as to:

                           -- one-third (1/3) of the total number of shares
                           covered by this option, as shown on the cover sheet
                           (the "Option Shares"), on the first anniversary of
                           the Vesting Start Date ("Anniversary Date"), provided
                           you then continue in Service.

                           -- provided you then continue in Service, one-third
                           (1/3) of the Option Shares shall vest on the second
                           Anniversary Date.

                           -- provided you then continue in Service, one-third
                           (1/3) of the Option Shares shall vest on the third
                           Anniversary Date.

                           Notwithstanding the vesting schedules set forth in
                           the preceding three subparagraphs, 100% of the Option
                           Shares shall become vested upon your termination by
                           the Company without cause (as defined in Section ___
                           of your Employment Agreement ("Cause")) or for good
                           reason (as defined in Section ___ of your Employment
                           Agreement ("Good Reason")) within 180 days following
                           a change of control pursuant to Section ___ of your
                           employment agreement with the Company dated
                           ___________________ (the "Employment Agreement").

                           The resulting aggregate number of vested shares will
                           be rounded to the nearest whole number, and you
                           cannot vest in more than the number of shares covered
                           by this option.

TERM                       Your option will expire in any event at the close of
                           business at Company headquarters on the day before
                           the 10th anniversary of the Grant Date, as shown on
                           the cover sheet. Your option will expire

<PAGE>

                           earlier if your Service terminates, as described
                           below.

REGULAR TERMINATION        If your Service terminates for any reason, other than
                           Death, Disability, Retirement, a Change in Control or
                           Termination by the Company with or without Cause,
                           then your option will expire at the close of business
                           at Company headquarters on the 90th day after your
                           termination date. Any and all unvested options are
                           forfeited as of your date of termination.

TERMINATION WITHOUT        If your service is terminated by the Company without
CAUSE OR FOR GOOD REASON   Cause or because you terminate your employment with
                           the Company for Good Reason, then your vested options
                           shall expire at the close of business thirty six (36)
                           months after your termination date. Any and all
                           unvested options are forfeited as of your date of
                           termination.

TERMINATION FOR CAUSE      If your Service is terminated by the Company for
                           Cause, then you shall immediately forfeit all rights
                           to your option and the option shall immediately
                           expire.

DEATH                      If your Service terminates because of your death,
                           then your option will expire at the close of business
                           at Company headquarters on the date 36 months after
                           the date of death. During that 36 month period, your
                           estate or heirs may exercise the vested portion of
                           your option.

                           IN ADDITION, IF YOU DIE DURING THE 90 DAY PERIOD
                           DESCRIBED IN CONNECTION WITH ANY TERMINATION OF YOUR
                           EMPLOYMENT OTHER THAN FOR CAUSE, AND A VESTED PORTION
                           OF YOUR OPTION HAS NOT YET BEEN EXERCISED, THEN YOUR
                           OPTION WILL INSTEAD EXPIRE ON THE DATE THIRTY SIX
                           (36) MONTHS AFTER YOUR TERMINATION DATE. IN SUCH A
                           CASE, DURING THE PERIOD FOLLOWING YOUR DEATH UP TO
                           THE DATE THIRTY SIX (36) MONTHS AFTER YOUR
                           TERMINATION DATE, YOUR ESTATE OR HEIRS MAY EXERCISE
                           THE VESTED PORTION OF YOUR OPTION.

DISABILITY                 If your Service terminates because of your permanent
                           and total disability, then your option will continue
                           to vest as if your Service had not terminated and
                           will expire at the close of business at Company
                           headquarters on the day before the 10th anniversary
                           of the Grant Date, as shown on the cover sheet.

LEAVES OF ABSENCE          For purposes of this option, your Service does not
                           terminate when you go on a bona fide employee leave
                           of absence that was approved by the Company in
                           writing, if the terms of the leave provide for
                           continued Service crediting, or when continued
                           Service crediting is required by applicable law.
                           However, your Service will be treated as terminating
                           90 days after you went on employee leave, unless your
                           right to return to active work is guaranteed by law
                           or by a contract. Your Service terminates in any
                           event when the approved leave ends

<PAGE>

                           unless you immediately return to active employee
                           work.

                           The Company determines, in its sole discretion, which
                           leaves count for this purpose, and when your Service
                           terminates for all purposes under the Plan.

RETIREMENT                 If your service terminates due to Normal Retirement,
                           defined as retirement at or after age 65, or Early
                           Retirement, defined as retirement at age 55 through
                           64 with at least three (3) years of service with the
                           Company, your option will expire at the close of
                           business at Company headquarters on the date that is
                           the earlier of three (3) years from your date of
                           retirement and the 10th Anniversary of the Grant
                           Date, as shown on the cover sheet. Any and all
                           unvested options as of your date of retirement are
                           forfeited.

NOTICE OF EXERCISE         When you wish to exercise this option, you must
                           notify the Company's designated agent filing in the
                           manner and form permitted by the designated agent.

                           If someone else wants to exercise this option after
                           your death, that person must prove to the Company's
                           satisfaction that he or she is entitled to do so.

FORM OF PAYMENT            When you submit your notice of exercise, you must
                           include payment of the option price for the shares
                           you are purchasing. Payment may be made in one (or a
                           combination) of the following forms:

                           - Cash, your personal check, a cashier's check, a
                           money order or another cash equivalent acceptable to
                           the Company.

                           - Shares of Stock which have already been owned by
                           you for more than six (6) months and which are
                           surrendered to the Company. The value of the shares,
                           determined as of the effective date of the option
                           exercise, will be applied to the option price.

                           - By delivery (on a form prescribed by the Company or
                           the designated agent) of an irrevocable direction to
                           a licensed securities broker acceptable to the
                           Company to sell Stock and to deliver all or part of
                           the sale proceeds to the Company in payment of the
                           aggregate option price and any withholding taxes (if
                           approved in advance by the Compensation Committee of
                           the Board if you are either an executive officer or a
                           director of the Company).

WITHHOLDING TAXES          You will not be allowed to exercise this option
                           unless you make acceptable arrangements to pay any
                           withholding or other taxes that may be due as a
                           result of the option exercise or sale of Stock
                           acquired under this option. In the event that the
                           Company

<PAGE>

                           determines that any federal, state, local or foreign
                           tax or withholding payment is required relating to
                           the exercise or sale of shares arising from this
                           grant, the Company shall have the right to require
                           such payments from you, or withhold such amounts from
                           other payments due to you from the Company or any
                           Affiliate.

TRANSFER OF OPTION         Except as provided in this section, during your
                           lifetime, only you (or, in the event of your legal
                           incapacity or incompetency, your guardian or legal
                           representative) may exercise this option and the
                           option shall not be assignable or transferable by
                           you, other than by designation of beneficiary, will
                           or the laws of descent and distribution. You may
                           transfer all or part of this option, not for value,
                           to any Family Member, provided that you provide prior
                           written notice to the Company, in a form satisfactory
                           to the Company, of such transfer. For the purpose of
                           this section, a "not for value" transfer is a
                           transfer which is (i) a gift, (ii) a transfer under a
                           domestic relations order in settlement of marital
                           property rights, or (iii) a transfer to an entity in
                           which more than fifty percent of the voting interests
                           are owned by Family Members (or you) in exchange for
                           an interest in that entity. Subsequent transfers of
                           transferred options are prohibited except to your
                           Family Members in accordance with this section or by
                           will or the laws of descent and distribution. The
                           events of termination of the Service this Agreement
                           shall continue to be applied with respect to you,
                           following which the option shall be exercisable by
                           the transferee only to the extent, and for the
                           periods specified in herein.

RETENTION RIGHTS           Neither your option nor this Agreement gives you the
                           right to be retained by the Company (or any Parent,
                           Subsidiaries or Affiliates) in any capacity. The
                           Company (and any Parent, Subsidiaries or Affiliates)
                           reserves the right to terminate your Service at any
                           time and for any reason.

SHAREHOLDER RIGHTS         You, or your designated beneficiary, estate or heirs,
                           have no rights as a shareholder of the Company until
                           a certificate for your option's shares has been
                           issued (or an appropriate book entry has been made).
                           No adjustments are made for dividends or other rights
                           if the applicable record date occurs before your
                           stock certificate is issued (or an appropriate book
                           entry has been made), except as described in the
                           Plan.

FORFEITURE OF RIGHTS       The Company at any time shall have the right to cause
                           a forfeiture of your rights on account of you taking
                           actions in competition with the Company. Unless
                           otherwise specified in an employment or other
                           agreement between the Company and you, you take
                           actions in competition with the Company if you
                           directly or indirectly own any interest in, operates,
                           joins, controls or participates as a partner,

                      EXECUTIVE RESTRICTED STOCK AGREEMENT

RESTRICTED STOCK/          This grant is an award of Stock in the number of
NONTRANSFERABILITY         shares set forth on the cover sheet, at the purchase
                           price set forth on the cover sheet, and subject to
                           the vesting conditions described below ("Restricted
                           Stock"). The purchase price for the Restricted Stock
                           is deemed paid by your services to the Company. To
                           the extent not yet vested, your Restricted Stock may
                           not be transferred, assigned, pledged or
                           hypothecated, whether by operation of law or
                           otherwise, nor may the Restricted Stock be made
                           subject to execution, attachment or similar process.

ISSUANCE AND VESTING       The Company will issue your Restricted Stock in your
                           name as of the Grant Date.

                                    Your rights to the shares of Stock under
                           this grant vest as to:

                                    -- one-third (1/3) of the total number of
                           shares covered by this grant, as shown on the cover
                           sheet (the "Shares"), on the third anniversary of the
                           Grant Date ("Anniversary Date"), provided you then
                           continue in Service.

                                    -- provided you then continue in Service,
                           one-third (1/3) of the Shares shall vest on the
                           fourth Anniversary Date.

                                    -- provided you then continue in Service,
                           one-third (1/3) of the Shares shall vest on the fifth
                           Anniversary Date.

                           Notwithstanding the vesting schedule set forth in the
                           preceding three subparagraphs, 100% of the shares
                           shall become vested upon your termination by the
                           Company with Cause or for good reason, as defined in
                           Section ___ of your Employment Agreement, within 180
                           days following a change in control pursuant to
                           Section ___ of your employment agreement with the
                           Company dated __________(the "Employment Agreement").
                           No additional shares of Stock will vest after your
                           Service has terminated for any reason.

                           The resulting aggregate number of vested shares will
                           be rounded to the nearest whole number, and you
                           cannot vest in more than the number of shares covered
                           by this grant.

FORFEITURE OF UNVESTED     Except as expressly provided herein, in the event
STOCK                      that your Service terminates for any reason, you will
                           forfeit to the Company all of the shares of Stock
                           subject to this grant that have not yet vested.

ESCROW                     The certificates for the Restricted Stock shall be
                           deposited in escrow with the Secretary of the Company
                           to be held in accordance with the provisions of this
                           paragraph. Each deposited certificate shall be
                           accompanied by a duly executed Assignment Separate
                           from Certificate

<PAGE>

                           in the form attached hereto as Exhibit A. The
                           deposited certificates shall remain in escrow until
                           such time or times as the certificates are to be
                           released or otherwise surrendered for cancellation as
                           discussed below. Upon delivery of the certificates to
                           the Company, you shall be issued an instrument of
                           deposit acknowledging the number of shares of Stock
                           delivered in escrow to the Secretary of the Company.

                           All regular cash dividends on the Stock (or other
                           securities at the time held in escrow) shall be paid
                           directly to you and shall not be held in escrow.
                           However, in the event of any stock dividend, stock
                           split, recapitalization or other change affecting the
                           Company's outstanding common stock as a class
                           effected without receipt of consideration or in the
                           event of a stock split, a stock dividend or a similar
                           change in the Company Stock, any new, substituted or
                           additional securities or other property which is by
                           reason of such transaction distributed with respect
                           to the Stock shall be immediately delivered to the
                           Secretary of the Company to be held in escrow
                           hereunder, but only to the extent the Stock is at the
                           time subject to the escrow requirements hereof.

                           As your interest in the shares vests, as described
                           above, the certificates for such vested shares shall
                           be released from escrow and delivered to you, at your
                           request, within 30 days of their vesting.

WITHHOLDING TAXES          You agree, as a condition of this grant, that you
                           will make acceptable arrangements to pay any
                           withholding or other taxes that may be due as a
                           result of the vesting of Stock acquired under this
                           grant. In the event that the Company determines that
                           any federal, state, local or foreign tax or
                           withholding payment is required relating to the
                           vesting of shares arising from this grant, the
                           Company shall have the right to require such payments
                           from you, or withhold such amounts from other
                           payments due to you from the Company or any
                           Affiliate.

SECTION 83(b) ELECTION     Under Section 83 of the Internal Revenue Code of
                           1986, as amended (the "Code"), the difference between
                           the purchase price paid for the shares of Stock and
                           their fair market value on the date any forfeiture
                           restrictions applicable to such shares lapse will be
                           reportable as ordinary income at that time. For this
                           purpose, "forfeiture restrictions" include the
                           forfeiture of unvested Stock that is described above.
                           You may elect to be taxed at the time the shares are
                           acquired, rather than when such shares cease to be
                           subject to such forfeiture restrictions, by filing an
                           election under Section 83(b) of the Code with the
                           Internal Revenue Service within thirty (30) days
                           after the Grant Date. You will have to make a tax
                           payment to the extent the purchase price is less than
                           the fair market value of the shares on the Grant
                           Date. No tax payment will have to be made to the
                           extent the purchase price is at least equal to the
                           fair market value of the shares on the Grant Date.
                           The form for making this election is attached as
                           Exhibit B hereto. Failure to make this filing within

                           the thirty (30) day period will result in the
                           recognition of ordinary income by you (in the event
                           the fair market value of the shares as of the vesting
                           date exceeds the purchase price) as the forfeiture
                           restrictions lapse.

                           YOU ACKNOWLEDGE THAT IT IS YOUR SOLE RESPONSIBILITY,
                           AND NOT THE COMPANY'S, TO FILE A TIMELY ELECTION
                           UNDER SECTION 83(b), EVEN IF YOU REQUEST THE COMPANY
                           OR ITS REPRESENTATIVES TO MAKE THIS FILING ON YOUR
                           BEHALF. YOU ARE RELYING SOLELY ON YOUR OWN ADVISORS
                           WITH RESPECT TO THE DECISION AS TO WHETHER OR NOT TO
                           FILE ANY 83(B) ELECTION.

RETENTION RIGHTS           This Agreement does not give you the right to be
                           retained by the Company (or any Parent, Subsidiaries
                           or Affiliates) in any capacity. The Company (and any
                           Parent, Subsidiaries or Affiliates) reserves the
                           right to terminate your Service at any time and for
                           any reason.

SHAREHOLDER RIGHTS         You have the right to vote the Restricted Stock and
                           to receive any dividends declared or paid on such

                           any stock split, stock dividend, combination of
                           shares or other similar transaction shall be deemed
                           to be a part of the Restricted Stock and subject to
                           the same conditions and restrictions applicable
