          3.       Taxes . You acknowledge that you are responsible for any and all amounts recognized for federal, state or local tax purposes on account of the vesting of RSUs and/or issuance of the shares of Common Stock to you. Your minimum statutory tax withholding obligations, if any, on account of the vesting of RSUs and/or issuance of shares of Common Stock will be satisfied by the Company withholding from the shares of Common Stock to be issued to you a sufficient number of whole shares of Common Stock distributable in connection with this Award equal to the applicable minimum statutory tax withholding obligation. Notwithstanding any provision herein to the contrary, in the event that this Award becomes subject to taxes under the Federal Insurance Contributions Act (“FICA”) or similar taxes before the shares of Common Stock under the Award would otherwise be issued, the Company shall issue to you a sufficient number of whole shares of Common Stock under this Award that does not exceed the applicable minimum statutory tax withholding obligation with respect to such FICA taxes and any federal, state or local income taxes that may apply as a result of such accelerated issuance of shares of Common Stock and the Company shall withhold such shares of Common Stock to satisfy such FICA and any related income tax liability; provided, however, that any such accelerated issuance of shares of Common Stock shall be made only to the extent permitted under Treas. Reg. § 1.409A-3(j)(4)(vi). In the event that you do not make tax payments when required, the Company may refuse to issue or cause to be delivered any shares of Common Stock under this RSU Agreement until such payment has been made or arrangements for such payment
