                           RESTRICTED SHARE AGREEMENT

RESTRICTED SHARES/      This grant is an award of Shares in the number of Shares
NONTRANSFERABILITY      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 Shares"). The
                        purchase price for the Restricted Shares may be paid in
                        either cash or check made payable to the Company, or may
                        be deemed paid by your services to the Company (if
                        approved by the Board of Directors or committee
                        administering the Plan). To the extent not yet vested,
                        your Restricted Shares may not be transferred, assigned,
                        pledged or hypothecated, whether by operation of law or
                        otherwise, nor may the Restricted Shares be made subject
                        to execution, attachment or similar process.

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

                        Your right to the Shares under this Restricted Share
                        Agreement grant vests as to the total number of Shares
                        covered by this grant, as shown on the cover sheet, on
                        the first anniversary of the Grant Date (an "Anniversary
                        Date"), provided you then continue in Service. If,
                        however, you are restricted from selling Shares on the
                        Anniversary Date pursuant to the Company's policy on
                        insider trading, your Shares that would have vested on
                        that vesting date will vest on the first date that is
                        during a window period in which Company insiders are not
                        restricted from selling Shares.

                        Your right to the Shares under this Restricted Share
                        Agreement will become fully vested on your termination
                        of Services due to death or disability (or such other
                        conditions permitted by a written employment agreement
                        with the Company). No additional Shares will vest after
                        your Service has terminated for any reason.

FORFEITURE OF UNVESTED  In the event that your Service terminates for any reason
SHARES                  other than death or disability, you will forfeit to the
                        Company all of the Shares subject to this grant that
                        have not yet vested (unless otherwise provided in your
                        employment agreement).

ESCROW                  The certificates for the Restricted Shares 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 delivered in
                        escrow to the Secretary of the Company.

                        All regular cash dividends on the Shares (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 dividend, split,
                        recapitalization or other change affecting the Company's
                        outstanding Shares as a class effected without receipt
                        of consideration or in the event of a split, a dividend
                        or a similar change in the Shares, any new, substituted
                        or additional securities or other property which is by
                        reason of such transaction distributed with respect to
                        the Shares shall be immediately delivered to the
                        Secretary of the Company to be held in escrow hereunder,
                        but only to the extent the Shares are 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 Shares 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)           Under Section 83 of the Internal Revenue Code of 1986,
ELECTION                as amended (the "Code"), the difference between the
                        purchase price paid for the Shares 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 Shares
                        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 Code Section
                        83(b) 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 CODE
                        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 CODE
                        SECTION 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 Shares and to
                        receive any dividends declared or paid on such Shares.
                        Any distributions you receive as a result of any split,
                        dividend, combination of Shares or other similar
                        transaction shall be deemed to be a part of the
                        Restricted Shares 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
                        share certificate is issued.

ADJUSTMENTS             In the event of a split, a dividend or a similar change
                        in the Shares, the number of Shares covered by this
                        grant may be adjusted (and rounded down to the nearest
                        whole number) pursuant to the Plan. Your Restricted
                        Shares shall be subject to the terms of the agreement of
                        merger, liquidation or reorganization in the event the
                        Company is subject to such corporate activity.

LEGENDS                 All certificates representing the Shares issued in
                        connection with this grant shall, where applicable, have
                        endorsed thereon the following legends:
