**NOW THEREFORE**, in consideration of services rendered and to be rendered by the Participant, and the mutual promises made herein and the mutual benefits to be derived therefrom, the parties agree as follows: 

**1.****Defined Terms**. Capitalized terms used herein and not otherwise defined herein shall have the meaning assigned to such terms inthe Plan.

Subject to the terms of this Agreement, the Corporation hereby grants to the Participant a StockUnit Award with respect to an aggregate of **[            ]** stock units (subject to adjustment as provided in Section 7.1 of the Plan) (the “**Stock Units**”).As used herein, the term “stock unit” shall mean a non-voting unit of measurement which is deemed for bookkeeping purposes to be equivalent to one outstanding share of the Corporation’s Common Stock (subject to adjustment as providedin Section 7.1 of the Plan) solely for purposes of the Plan and this Agreement. The Stock Units shall be used solely as a device for the determination of the payment to eventually be made to the Participant if such Stock Units vest pursuant toSection 3.

**3.****Vesting**. Subjectto Section 8 and Section 9 below, the Award shall vest and become nonforfeitable with respect to one-third of the total number of Stock Units (subject to adjustment under Section 7.1 of the Plan) on each of the first, second and thirdanniversaries of the Award Date. 

**4.****Continuance of Employment**. The vesting schedule requires continued employment orservice through each applicable vesting date as a condition to the vesting of the applicable installment of the Award and the rights and benefits under this Agreement. Employment or service for only a portion of the vesting period, even if asubstantial portion, will not entitle the Participant to any proportionate vesting or avoid or mitigate a termination of rights and benefits upon or following a termination of employment or services as provided in Section 8(a) below or underthe Plan. 

Nothing contained in this Agreement or the Plan constitutes an employment or service commitment by the Corporation, affects theParticipant’s status as an employee at will who is subject to termination without cause, confers upon the Participant any right to remain employed

by or in service to the Corporation or any Subsidiary, interferes in any way with the right of the Corporation or any Subsidiary at any time to terminatesuch employment or services, or affects the right of the Corporation or any Subsidiary to increase or decrease the Participant’s other compensation or benefits. Nothing in this paragraph, however, is intended to adversely affect any independentcontractual right of the Participant without his consent thereto. 

**5.****Dividend and Voting Rights**. 

(a) **Limitations on Rights Associated with Units**.

No adjustments will be made for dividends or other rights of a holder for which the record date is prior to the date of issuance of the stockcertificate. 

(b) **Dividend Equivalent Rights Distributions**. In the event that the Corporation pays anordinary cash dividend on its Common Stock and the related dividend payment record date occurs at any time after the Award Date and before all of the Stock Units subject to the Award have either been paid pursuant to Section 7 or terminatedpursuant to Section 8(a), the Corporation shall credit the Participant as of such record date with an additional number of Stock Units equal to (i) the per-share cash dividend paid by the Corporation on its Common Stock with respect tosuch record date, multiplied by (ii) the total number of outstanding and unpaid Stock Units (including any dividend equivalents previously credited hereunder) (with such total number adjusted pursuant to Section 7.1 of the Plan and/orSection 9 hereof) subject to the Award as of such record date, divided by (iii) the fair market value of a share of Common Stock (as determined under the Plan) on such record date. Any Stock Units credited pursuant to the foregoingprovisions of this Section 5(b) shall be subject to the same vesting, payment and other terms, conditions and restrictions as the original Stock Units to which they relate.
