Among other things, Mr. Howsman is also entitled to receive a pro-rated  short-term incentive for the 2019 fiscal year, based on actual results for the full fiscal year, to be paid at the same time that short-term incentives for the year are paid by the Company to other participants under the short-term incentive plan. All restricted share units held by Mr. Howsman vested, to the extent provided under the terms and conditions of the applicable award agreements, as if his employment was terminated without cause on the separation date.

Mr. Howsman has agreed to provide consulting services to the Company for a period of up to 90 days after his resignation. He will not receive any additional consideration for such services.
