Upon any exercise of the Option, an amount necessary to pay the exercise price and to satisfy applicable tax withholding requirements, including those arising under federal, state and local income tax laws, will be due and payable at the time of exercise prior to the issuance of any shares of Common Stock pursuant to such exercise.  The Grantee may pay the exercise price and satisfy the minimum withholding requirements by one or more of the following methods:  (a) in cash, (b) in cash received from a broker-dealer to whom the Grantee has submitted an exercise notice and irrevocable instructions to deliver the purchase price and amount of tax withholding to the Company from the proceeds of the sale of shares of Common Stock subject to the Option, (c) by delivery to the Company of other Common Stock owned by the Grantee that is acceptable to the Company, valued at its fair market value on the date of exercise, (d) by certifying to ownership by attestation of such previously owned Common Stock, or (e) by having shares withheld from the Common Stock otherwise distributable to the Grantee upon exercise of the Option. A Grantee’s election pursuant to the preceding sentence must be made at the time of exercise of such Option and must be irrevocable.  Payment shall be made pursuant to the online procedures set forth on the AAR 2013 Stock Benefit Plan online website through Morgan Stanley (www.stockplanconnect.com).
