Provision: (a) Prior to any relevant tax or tax withholding event (as applicable) and as a condition of your receiving the shares of Common Stock in respect of the Stock Units, you agree to make arrangements satisfactory to NCR and/or the Employer to satisfy all income tax, social insurance tax, payroll tax, fringe benefits tax or other Federal, state or local tax payment or withholding requirements or other tax related items (collectively, “Tax-Related Items”) applicable to you as a result of or related to your participation in the Plan. In this regard, you agree to pay to NCR, including, at NCR’s sole discretion, through payroll withholding or other method prescribed by the Chief Human Resources Officer, an amount equal to the amount of such Tax-Related Items required to be paid or withheld with respect to the Stock Units as determined in the sole discretion of NCR; provided that you will be required to pay any such amount prior to the tax or tax withholding event (as applicable) and as a condition of your receiving the shares of Common Stock to be issued in respect of the Stock Units. Such payment of Tax-Related Items shall be made by NCR withholding shares of Common Stock that are issuable upon the settlement of the Stock Units equal to the amount required to be withheld or paid as determined by NCR, except to the extent that: (i) the Chief Human Resources Officer permits payment for such Tax-Related Items in cash by an employee other than an executive officer of NCR (“Executive Officer”) subject to Section 16 of the Securities Exchange Act of 1934, as amended (the “Act”), or (ii) you are an Executive Officer and you elect to make payment for such Tax-Related Items in cash or by instructing NCR and any brokerage firm determined acceptable to NCR for such purpose to sell on your behalf the whole number of shares of Common Stock underlying the Stock Units that NCR determines to be appropriate to generate the cash proceeds sufficient to satisfy such Tax-Related Items. Any withholding of shares or sale or cash payment pursuant to this Section shall occur on the date that the requirement to withhold or pay taxes arises, or as soon as practicable thereafter if permitted by NCR. To the extent that you are an Executive Officer who instructs a brokerage firm sale permitted by this Section, you will be responsible for, and will indemnify and hold NCR and the Employer harmless with respect to, any and all losses, costs, damages or other expenses (including brokerage fees and other similar costs related directly to any such sale of Common Stock) arising in connection with, or related to, any such sale. You acknowledge that if, at the time any shares of Common Stock are sold to satisfy requirements relating to Tax-Related Items pursuant to this Section, you are an Executive Officer as defined above, any such sale of Common Stock must be made pursuant to an exemption from the requirements under Section 16(b) of the Act.
