<TABLE>
<S>                        <C>
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.

                           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.

                           No additional shares of Stock will vest after your
                           Service has terminated for any reason.

FORFEITURE OF UNVESTED     In the event that your Service terminates for any
STOCK                      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 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
                           stock. Any distributions you receive as a result of
                           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
                           thereto. The Company may in its sole discretion
                           require any dividends paid on the Restricted Stock to
                           be reinvested in shares of Stock, which the Company
                           may in its sole discretion deem to be a part of the
                           shares of Restricted Stock and subject to the same
                           conditions and restrictions applicable thereto.
                           Except as described in the Plan, no adjustments are
                           made for dividends or other rights if the applicable
                           record date occurs before your
                           stock certificate is issued.

FORFEITURE OF RIGHTS       If you should take actions in competition with the
                           Company, the Company shall have the right to cause a
                           forfeiture of your unvested Restricted Stock, and
                           with respect to those shares of Restricted Stock
                           vesting during the period commencing twelve (12)
                           months prior to your termination of Service with the
                           Company due to taking actions in competition with the
                           Company, the right to cause a forfeiture of those
                           vested shares of Stock (but the Company will pay you
                           the purchase price without interest).

                           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, manage, operate, join or
                           control, or participate in the ownership, management,
                           operation or control of, or are a proprietor,
                           director, officer, stockholder, member, partner or an
                           employee or agent of, or a consultant to any
                           business, firm, corporation, partnership or other
                           entity which competes with any business in which the
                           Company or any of its Affiliates is engaged during
                           your employment or other relationship with the

                           your termination of Service.

ADJUSTMENTS                In the event of a stock split, a stock dividend or a
                           similar change in the Company stock, the number of

                           number) pursuant to the Plan. Your Restricted Stock
