                           RESTRICTED STOCK AGREEMENT

RESTRICTED STOCK/NONTRANSFERABILITY. This grant is an award of Stock in the
number of shares set forth on the cover sheet and subject to the vesting
conditions described below and the Plan ("Restricted Stock"). 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 right to the Stock under this Restricted Stock grant
vests as to 100% of the total number of shares covered by this grant, as shown
on the cover sheet, on May 10, 2005; provided that you remain continuously
employed with the Company throughout the vesting period.

Notwithstanding the preceding paragraph your right to the Stock under this
Restricted Stock grant shall immediately vest as to 100% of the total number of
shares covered by this grant upon the occurrence of either:

            -     your termination of Service due to your death or permanent and
                  total disability, or your involuntary termination of Service
                  other than by reason of your willful refusal to perform your
                  duties; or

            -     a "Change of Control" of the Company prior to your termination
                  of Service. For purposes of this Agreement, Change of Control
                  means, if, at any time prior to the vesting of the Restricted
                  Stock, (i) the individuals who presently constitute the Board
                  of Directors of the Company, or who have been recommended for
                  election to the Board by two-thirds of the Board consisting of
                  individuals who are either presently on the Board or such
                  recommended successors cease for any reason to constitute at
                  least a majority of such Board, or (ii) any person or entity
                  or group of affiliated persons or entities who are not the
                  owners of at least 15% of the outstanding shares of voting
                  securities of the Company on the date hereof, acquiring more
                  than 25% of the outstanding shares of the Company's voting
                  securities.

      You will return the certificate representing the Restricted Stock, and the
Restricted Stock shall be deemed no longer outstanding, to the extent the
Restricted Stock does not become vested in accordance with the foregoing
provisions.

SECTION 83(b) ELECTION. Under Section 83 of the Internal Revenue Code of 1986,
as amended (the "Code"), the difference between the purchase price, if any, 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. 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

                                       2
<PAGE>

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 A 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 increases after
the date of purchase) as the forfeiture restrictions lapse.

SHAREHOLDER RIGHTS. You have the right to vote the 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 Stock and subject to the
same conditions and restrictions applicable thereto. The Company may in its sole
discretion require any dividends paid on the 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 Stock and subject to the same conditions and restrictions applicable
thereto.

ADJUSTMENTS. In the event of a stock split, a stock dividend or a similar change
in the Company stock, the number of shares covered by this grant shall be
adjusted (and rounded down to the nearest whole number).

COMPLIANCE WITH LAW. The issuance of this Stock shall be subject to compliance
with the rules and policies of the New York Stock Exchange. The shares of Stock
have not been registered under the Securities Act of 1933 as amended (the
"Act"), may be "restricted securities" as defined in Rule 144 promulgated under
the Act, and may not be sold or otherwise disposed of except in compliance with
applicable provisions of the Act. At your request, the Company will, at its
expense, cause such shares to be duly and promptly registered for resale by you
under the Act after vesting of such shares; provided that you will have the
right to request one demand registration and unlimited "piggyback"
registrations.

LEGENDS. All certificates representing the Stock issued in connection with this
grant shall, where applicable, have endorsed thereon the following legends: "THE
SHARES REPRESENTED BY THIS CERTIFICATE ARE SUBJECT TO CERTAIN RESTRICTIONS SET
FORTH IN AN AGREEMENT BETWEEN THE COMPANY AND THE REGISTERED HOLDER, OR HIS OR
HER PREDECESSOR IN INTEREST. A COPY OF SUCH AGREEMENT IS ON FILE AT THE
PRINCIPAL OFFICE OF THE COMPANY AND WILL BE FURNISHED UPON WRITTEN REQUEST TO

SUCH ACT AND SUCH APPLICABLE STATE OR OTHER JURISDICTION'S SECURITIES LAWS OR AN
OPINION OF COUNSEL, SATISFACTORY TO THE COMPANY AND ITS COUNSEL, THAT SUCH
REGISTRATION AND QUALIFICATION IS NOT REQUIRED."

NON-RAIDING AND NON-COMPETE. You agree that during the Term hereof and, (i) in
the event

                                       3

of one (1) year following the termination of the your employment for any reason,
