3.
    
    Effect of Change in Control.In the event a Change of Control occurs during the Performance
Period, but before the payment of any performance shares as set forth in Section 6, below, the
Company shall pay to the Grantee, as soon as practicable following the Change of Control but
in no event later than two and one-half months following the end of the year in which the
Change of Control occurs, a pro rata number of the Target Performance Shares based on the
number of full months that have elapsed during the Performance Period prior to the Change of
Control, and the remaining performance shares will be forfeited.
 4.
    
    Termination Due to Death, Disability, Retirement.If the Grantees employment with the
Company or a Subsidiary terminates during the Performance Period, but before the payment of
any performance shares as set forth in Section 6, below, due to (a) the Grantees death or (b)
the Grantee becoming permanently and totally disabled while in the employ of the Company or
any Subsidiary or (c) the Grantees Retirement, the Company shall pay to the Grantee or his or
her executor or administrator, as the case may be, at the time described in Section 6 and
based on the level of achievement of Total Stockholder Return during the Performance Period, a
pro rata number of the Target Performance Shares based on the number of full months during the
Performance Period during which the Grantee was employed by the Company, and the remaining
performance shares will be forfeited. The Grantee shall be considered to have become
permanently and totally disabled if the Grantee has suffered a total disability within the
meaning of the Companys Long Term Disability Plan for Salaried Employees. Retirement shall
mean the Grantees retirement under a retirement plan (including, without limitation, any
supplemental retirement plan) of the Company or any Subsidiary, or the Grantees retirement
from employment with the Company or any Subsidiary after completing at least three years of
continuous service with the Company or any Subsidiary and attaining the age of 62. Without
limiting the generality of the foregoing, in no event shall Retirement include the
involuntary termination of the Grantees employment by the Company (i) for cause or (ii)
without cause if, as a result of such termination without cause, the Grantee becomes eligible
to receive payments on account of such termination under an employment agreement between the
Grantee and the Company.
 5.
    
    Forfeiture.If either (i) the Grantees employment with the Company or a Subsidiary
terminates before the end of the Performance Period, and before the occurrence of a Change of
Control, for any reason other than as set forth in Section 4 hereof or (ii) the Board (or a
committee of the Board) finds that the Grantee has engaged in any fraud or intentional
misconduct as described in Section 20 hereof, the Performance Shares will be forfeited.
 6.
    
    Form and Time of Payment of Performance Shares.Payment of any performance shares that
become earned as set forth herein will be made in the form of Common Shares. Except as
otherwise provided in Section 3, payment will be made as soon as practicable after the end of
the Performance Period and the determination by the Board of the level of

attainment of Total Stockholder Return, but in no event shall such payment occur later than
two and one-half months after the end of the Performance Period. Performance shares will be
forfeited if they are not earned at the end of the Performance Period and, except as
otherwise provided in this Agreement, if the Grantee ceases to be employed by the Company or
a Subsidiary at any time prior to such performance shares becoming earned at the end of the
Performance Period. To the extent that the Company or any Subsidiary is required to
withhold any federal, state, local or foreign tax in connection with the payment of earned
performance shares pursuant to this Agreement, it shall be a condition to the receipt of
such performance shares that the Grantee make arrangements satisfactory to the Company or
such Subsidiary for payment of such taxes required to be withheld, which may include by
having the Company withhold Common Shares otherwise payable pursuant to this award.
 7.
    
    Payment of Dividends.No dividends shall be accrued or earned with respect to the
performance shares until such performance shares are earned by the Grantee as provided in this
Agreement.
 8.
    
    Performance Shares Nontransferable.Until payment is made to the Grantee as provided herein,
neither the Performance Shares granted hereby nor any interest therein or in the Common Shares
related thereto shall be transferable other than by will or the laws of descent and
distribution prior to payment.
 9.
    
    Adjustments.In the event of any change in the aggregate number of outstanding Common Shares
by reason of (a) any stock dividend, extraordinary dividend, stock split, combination of
shares, recapitalization or other change in the capital structure of the Company, or (b) any
Change in Control, merger, consolidation, spin-off, split-off, spin-out, split-up,
reorganization or partial or complete liquidation, or other distribution of assets, issuance
of rights or warrants to purchase securities, or (c) any other corporate transaction or event
having an effect similar to any of the foregoing, then the Board shall adjust the number of
Performance Shares then held by the Grantee in such manner as to prevent dilution or
enlargement of the rights of the Grantee that otherwise would result from such event.
Moreover, in the event of any such transaction or event, the Board (or a committee of the
Board), in its discretion, may provide in substitution for any or all of the Grantees rights
under this Agreement such alternative consideration as it may determine to be equitable in the
circumstances.
 10.
    
    Compliance with Section 409A of the Code.To the extent applicable, it is intended that this
Agreement and the Plan comply with the provisions of Section 409A of the Code, so that the
income inclusion provisions of Section 409A(a)(1) of the Codedo not apply to the
Grantee. This Agreement and the Plan shall be administered in a manner consistent with this
intent. Reference to Section 409A of the Code is to Section 409A of the Internal Revenue Code
of 1986, as amended, and will also include any regulations or any other formal guidance
promulgated with respect to such Section by the U.S. Department of the Treasury or the
Internal Revenue Service.

11.
    
    No Right to Future Grants; No Right of Employment; Extraordinary Item:In accepting the
grant, Grantee acknowledges that: (a) the Plan is established voluntarily by the Company, it
is discretionary in nature and it may be modified, suspended or terminated by the Company at
any time, as provided in the Plan and this Award Agreement; (b) the grant of the Performance
Shares is voluntary and occasional and does not create any contractual or other right to
receive future grants of Performance Shares or benefits in lieu of Performance Shares, even
if Performance Shares have been granted repeatedly in the past; (c) all decisions with respect
to future grants, if any, will be at the sole discretion of the Company; (d) your
participation in the Plan is voluntary; (e) the Performance Shares are an extraordinary item
that does not constitute compensation of any kind for services of any kind rendered to the
Company, its Affiliates and/or Subsidiaries, and which is outside the scope of Grantees
employment contract, if any; (f) the Performance Shares are not part of normal or expected
compensation or salary for any purposes, including, but not limited to, calculating any
severance, resignation, termination, redundancy, end of service payments, bonuses,
long-service awards, pension or retirement benefits or similar payments; (g) in the event that
Grantee is an employee of an Affiliate or Subsidiary of the Company, the grant will not be
interpreted to form an employment contract or relationship with the Company; and furthermore,
the grant will not be interpreted to form an employment contract with the Affiliate or
Subsidiary that is Grantees employer; (h) the future value of the underlying Shares is
unknown and cannot be predicted with certainty; (i) no claim or entitlement to compensation or
damages arises from forfeiture or termination of the Performance Shares or diminution in value
of the Performance Shares or the Shares and Grantee irrevocably releases the Company, its
Affiliates and/or its Subsidiaries from any such claim that may arise; and (j) notwithstanding
any terms or conditions of the Plan to the contrary, in the event of involuntary termination
of Grantees employment, Grantees right to receive Performance Shares and vest in Performance
Shares under the Plan, if any, will terminate effective as of the date that Grantee is no
longer actively employed and will not be extended by any notice period mandated under local
law (e.g., active employment would not include a period of garden leave or similar period
pursuant to local law); furthermore, in the event of involuntary termination of employment,
Grantees right to vest in the Performance Shares after termination of employment, if any,
will be measured by the date of termination of Grantees active employment and will not be
extended by any notice period mandated under local law.
 12.
    
    Continuous Employment.For purposes of this Agreement, the continuous employment of the
Grantee with the Company or a Subsidiary shall not be deemed to have been interrupted, and the
Grantee shall not be deemed to have ceased to be an employee of the Company or Subsidiary, by
reason of (a) the transfer of the Grantees employment among the Company and its Subsidiaries
or (b) an approved leave of absence.
 13.
    
    Employee Data Privacy:Grantee hereby explicitly and unambiguously consents to the
collection, use and transfer, in electronic or other form, of Grantees personal data as
