4.Vesting and Forfeiture.

(c)    The Award shall not be vested as of the Grant Date set forth in the Term Sheet and shall be forfeitable unless and until otherwise vested pursuant to the terms of the Term Sheet and these Standard Terms and Conditions. After the Grant Date, subject to termination or acceleration as provided in these Standard Terms and Conditions, the Term Sheet, and the Plan, the Award shall become vested as described in the Vesting Schedule of the Term Sheet; provided that the Grantee remains continuously employed by the Company through the Vesting Date and also through the date settlement occurs. Each restricted stock unit credited under Section 6 in respect of Dividend Equivalents shall vest at the time of vesting of the portion of the Award that gives rise, directly or indirectly, to such Dividend Equivalent.

(d)    Except as set forth in Sections 4(c) and 4(d) hereof, upon the date Grantee’s employment with the Company terminates for any reason, the then unvested portion of the Award shall be forfeited by Grantee and cancelled and surrendered to the Company without payment of any consideration to Grantee.

(e)    If Grantee’s employment with the Company ceases due to death, Disability or termination by the Company without Cause, Grantee will become vested in a pro rata portion of his or her restricted stock units. That pro-rata portion will be determined by multiplying the number of restricted stock units subject to this Award by the Applicable Fraction.

(f)    Notwithstanding anything in Section 4(c) to the contrary, if Grantee’s employment with the Company ceases within one year following a Change in Control due to a termination by the Company without Cause (and other than by reason of Grantee’s death or Disability) or upon Grantee’s resignation for Good Reason, Grantee will become vested in 100% of the Award.

(g)    Settlement for restricted stock units that become vested pursuant to Section 4(c) or Section 4(d), will occur, subject to the terms of the LTCP and the Plan, as soon as administratively practicable after the termination of employment, but in no event later than by the first March 15 following the termination of employment.

5.Settlement. Unless otherwise set forth herein, each restricted stock unit credited hereunder (including restricted stock units credited in respect of Dividend Equivalents) will be settled by the delivery of one share of Common Stock (subject to adjustment under Section 12 of the Plan). Subject to Section 4(e) hereof, settlement will occur as soon as administratively practicable following the Vesting Date, but in no event later than by the first March 15 following the Vesting Date.

6.Dividend Equivalents and Adjustments. Dividend Equivalents shall be credited on the restricted stock units subject to this Award (other than restricted stock units that, at the relevant record date, previously have been settled or forfeited) in accordance with this Section 6:

(h)    Cash Dividends. If the Company declares and pays a dividend or distribution on its Shares in the form of cash, then a number of additional restricted stock units shall be credited to Grantee’s Account as of the payment date for such dividend or distribution equal to the number of restricted stock units credited to the Account as of the record date for such dividend or distribution, multiplied by the amount of cash actually paid as a dividend or distribution on each outstanding Share at such payment date, divided by the Fair Market Value of a Share as of such payment date.

(i)    Non‑Cash Dividends. If the Company declares and pays a dividend or distribution on Shares in the form of property other than Shares, then a number of additional restricted stock units shall be credited to Grantee’s Account as of the payment date for such dividend or distribution equal to the number of restricted stock units credited to the Account as of the record date for such dividend or distribution, multiplied by the Fair Market Value of such property actually paid as a dividend or distribution on each outstanding Share at such payment date, divided by the Fair Market Value of a Share as of such payment date.

(j)    Stock Dividends. If the Company declares and pays a dividend or distribution on Shares in the form of additional Shares, then a number of additional restricted stock units shall be credited to Grantee’s Account as of the payment date for such dividend or distribution equal to the number of restricted stock units credited to the Account as of the record date for such dividend or distribution or split, multiplied by the number of additional Shares actually paid as a dividend or distribution or issued in such split in respect of each outstanding Share.

7.Other Terms Relating to Restricted Stock Units.

(k)    The number of restricted stock units credited to a Grantee’s Account shall include fractional restricted stock units calculated to at least three decimal places, unless otherwise determined by the Administrator. Upon settlement of restricted stock units, Grantee shall be paid, in cash, an amount equal to the value of any fractional Share that would have otherwise been deliverable in settlement of such restricted stock units.

(l)    It shall be a condition to the Company’s obligation to issue and deliver Shares in settlement of the restricted stock units that Grantee (or the person to whom ownership rights may have passed by will or the laws of descent and distribution) pay to the Company, upon its demand, such amount as may be required by the Company for the purpose of satisfying any liability to withhold federal, state, or local income or other taxes. If the amount required is not paid, the Company may refuse to deliver the Shares in settlement of the restricted stock units until such amount is paid. The Administrator may, in its discretion, permit a Grantee (or the person to whom ownership rights may have passed by will or the laws of descent and distribution) to pay all or a portion of the amount required by the Company for such tax withholding, at such time and in such manner as the Administrator shall deem to be appropriate, including by authorizing the Company to withhold from the Shares to be delivered in settlement, or by agreeing to surrender to the Company on or about the date such tax liability is determinable, Shares having a Fair Market Value on such date equal to the amount of such tax liability or a specified portion of such tax liability.

8.Rights as Stockholder. Excepts with respect to Dividend Equivalents as set forth herein, Grantee will not be entitled to any privileges of ownership of the shares of Common Stock (including, without limitation, any voting rights) underlying the Award (whether or not vested) unless and until shares of Common Stock are actually delivered to Grantee hereunder.

9.Absence of Tax Gross-Up Payment. There shall be no tax gross-up on the restricted stock units.

(o)    Notwithstanding anything to the contrary contained herein, if the Administrator determines in good faith that the Awards do not qualify for the “short-term deferral exception” under Section 409A, (i) (x) if Grantee is a “specified employee” (as defined in Section 409A) and (y) a delay in the issuance or transfer of vested shares of Common Stock to Grantee or his or her estate or beneficiaries hereunder by reason of Grantee’s “separation from service” (as defined in Section 409A) with the Company or any of its subsidiaries or affiliates is required to avoid tax penalties under Section 409A but is not already provided for by this Award, the Company shall cause the issuance or transfer of such vested shares of Common Stock to Grantee or Grantee’s estate or beneficiary upon the earlier of (A) the date that is the first business day following the date that is six months after the date of Grantee’s separation from service or (B) Grantee’s death and (ii) for purposes hereof, a Change of Control shall not have occurred unless such Change of Control is a “change in the ownership or effective control” or a “change in the ownership of a substantial portion of the assets” of the Company, in each case, as determined in accordance with Section 409A, and, if a Change of Control has not occurred as a result of the application of this clause (ii) of this Section 13(c), the issuance or transfer of any vested shares of Common Stock shall occur on the date of Grantee’s separation from service as determined in accordance with Section 409A.
