Item 5.02. Departure of Directors or Certain Officers; Election of Directors; Appointment of Certain Officers; Compensatory Arrangements of Certain Officers.

On November 16, 2012, the Compensation Committee of our Board of Directors approved a grant of 45,580 restricted stock units to Timothy R. McLevish, our Executive Vice President and Chief Financial Officer. This award was made in recognition of Mr. McLevish’s leadership in successfully completing our spin-off from Kraft Foods Inc. on October 1, 2012. Two-thirds of the restricted stock units will vest on November 17, 2014, and the remaining one-third of the restricted stock units will vest on November 16, 2015. This description of the restricted stock unit award is qualified in its entirety by reference to the complete terms and conditions of the form of restricted stock unit agreement, which we will file as an exhibit to our Annual Report on Form 10-K for the year ended December 31, 2012.

Also, on November 21, 2012, we entered into a letter agreement with Mr. McLevish, the terms of which were approved by our Compensation Committee. The letter agreement provides that, upon any termination of employment of Mr. McLevish, without cause, either voluntary or involuntary, Mr. McLevish would receive a prorated portion of his annual target cash incentive award payable based on actual business performance and paid at the same time as Kraft makes payments to active employees.

The letter agreement also provides that his unvested restricted stock awards or restricted stock unit awards and performance shares granted under our long-term incentive plan will vest pro rata based on the number of full years completed in the vesting period or performance period, as applicable. However, with respect to his November 16, 2012 restricted stock unit award described above, if Mr. McLevish voluntarily terminates, any unvested shares will be forfeited. If his termination is involuntary without cause or upon mutual agreement, the restricted stock units would pro rata vest in the same manner as his other restricted stock unit awards described above. The number of performance shares that vest will also be based on the actual business rating for each applicable performance cycle, and the shares will be delivered to Mr. McLevish at the same time as active employees’ awards vest. In addition, Mr. McLevish’s unvested options granted in the years prior to his termination date would continue to vest in accordance with their terms, and he would have the full terms of the options to exercise. Any option awards granted in the year of his termination would be forfeited.

Further, Mr. McLevish agrees that upon termination, he will be subject to a general release of claims with respect to Kraft and non-compete, non-solicitation and confidentiality restrictions. The non-compete and non-solicitation restrictions would be in force for two years after he leaves Kraft.

The above description of the letter agreement is qualified in its entirety by reference to the complete terms and conditions of the agreement, which we will file as an exhibit to our Annual Report on Form 10-K for the year ended December 31, 2012.
