Grant of Restricted Stock Units. ​ hereby grants to the Participant the number of Restricted Stock Units representing the right to receive shares of common stock, par value of US$5.00 per share, of ​ (“Common Stock”) specified in the grant summary for no cash consideration, and dividend equivalent amounts corresponding to the shares, subject to the following terms and conditions:

Award of Restricted Stock Units. The Company grants to Participant an award (the “Award”) of performance-based restricted stock units (“Restricted Stock Units” or “Units”), pursuant to, and subject to, the terms of the Plan. The Award is based on a target award value of <# of Units> Units (the “Target Award Units”). The number of Restricted Stock Units that are ultimately earned pursuant to the Award (if any) will be determined based on the Target Award Units and the procedures and calculations set forth in this Agreement. Under the calculations set forth below, the maximum potential Award is a number of Units equal to two (2.0) times the sum of Target Award Units plus any related Dividend Equivalent Units (the “Maximum Award Units”). The Award is not intended to qualify as “performance-based compensation” under [Section 162(m)(4)(C)] of the Code.

Grant of Restricted Stock Units. The Company hereby grants to you, subject to the terms and conditions in this Agreement and the Plan, an Award of the number of restricted Stock Units (“Units”) specified on the cover page of this Agreement, each representing the right to receive one Share of the Company’s Stock. The Units granted to you will be credited to an account in your name maintained by the Company. This account shall be unfunded and maintained for book-keeping purposes only, with the Units simply representing an unfunded and unsecured obligation of the Company.

Term of Restricted Stock Units. The “Restricted Period” for the Award is the period beginning on ​ (the “Award Date”) and ending on the three year anniversary of the Award Date. The Participant will have no voting rights with respect to the Restricted Stock Units or any shares of Stock underlying the Restricted Stock Units until the shares of Stock are issued in settlement of the vested Restricted Stock Units.

Award of Restricted Stock Units. The Corporation hereby grants to the Participant on Award Date /$AwardsGranted$/ Restricted Stock Units. Each Restricted Stock Unit is a contingent right to receive a Restricted Stock Unit Share, subject to the restrictions and other terms and conditions set forth in the Plan and this Agreement. The Participant’s Award of Restricted Stock Units will be recorded in a memorandum account. The Participant will have no beneficial ownership interest in the Common Stock of the Corporation represented by the Restricted Stock Units awarded until the Participant receives a distribution of Restricted Stock Unit Shares.

Award of Restricted Stock Units. A record of the Units awarded hereunder (the “Units”) shall be evidenced by the Company in restricted book entry accounts maintained for the Employee with the Company’s transfer agent, or such other administrator designated by the Compensation and Human Resources Committee of the Company’s Board of Directors (the “Committee”), subject to such restrictions and other terms deemed appropriate by the Committee to be applicable to such Award (the “Restrictions”), until all the Restrictions specifically set forth in this Agreement and in Section 9 of the Plan with respect to the Units shall expire or be canceled. Upon the lapse of Restrictions relating to any Units, the Company shall deliver to the participant certificates for the Shares underlying the vested Units (or an applicable book entry shall be made in the restricted book entry account maintained for the Employee for the Shares underlying the vested Units). The Units shall have no voting rights. The Units shall be credited with Dividend Equivalents as set forth in Section 9 of the Plan. However, Dividend Equivalents paid with respect to Shares underlying the Units shall be credited to a restricted book entry account maintained on the Employee’s behalf until the Restrictions with respect to the Units upon which such Dividend Equivalents were paid expire or are canceled, at which time the Company shall evidence the delivery to the Employee of all such Dividend Equivalents, with interest if any. If the Employee forfeits any Units awarded hereunder, such Units and any Dividend Equivalents credited with respect thereto, with interest, if any, shall automatically revert to the Company (without any payment by the Company to the Employee) and shall no longer be reflected in the restricted book entry account for the Employee.

Settlement of Restricted Stock Units. Subject to the other provisions of the Plan, after the Lapse Date of the Period of Restriction as set forth in Paragraph 2, such Restricted Stock Units shall be settled as follows:

EARNING OF PERFORMANCE UNITS/SHARES. Subject to the terms of this Plan, after the applicable Performance Period has ended, the holder of Performance Units/Shares shall be entitled to receive payout on the number and value of Performance Units/Shares earned by the Participant over the Performance Period, to be determined as a function of the extent to which the corresponding performance goals have been achieved, as established by the Committee.

Stock Units. Dividend Equivalents shall be credited with respect to each Stock Unit credited to a Director on each dividend record date. Such Dividend Equivalents shall themselves be converted into Stock Units as of the dividend payment by dividing the amount of the Dividend Equivalents by the Value of the Company’s common stock as of the dividend payment date. Dividend Equivalents shall be credited on Stock Units attributable to a deferral of Director’s Fees and, except as otherwise provided by the terms of a Deferred Equity-Based Award, Stock Units attributable to Deferred Equity-Based Awards.

Stock Units. Each Stock Unit shall represent an unfunded and unsecured promise by the Company to issue cash equal in value to the Stock Unit. Participants holding Stock Units (or fractions thereof) shall earn dividend equivalents paid in the form of additional Stock Units added to their account. The number of Stock Units so added shall equal the dividend on a Share multiplied by the number of Stock Units held by the Participant on the record date for such dividend, divided by the Fair Market Value of a Share on the last Trading Day in the calendar month in which the record date for such dividend occurs. The Stock Units shall be credited to a Participant's account on the day the number of Stock Units is determined.
