Rule 10b5-1 trading arrangement that is intended to provide for “eligible sell-to-cover transactions” (as described in Rule 10b5-1(c)(1)(ii)(D)(3) under the Exchange Act) to satisfy tax withholding obligations arising exclusively from vesting of RSUs or PRUs. The number of shares subject to covered RSUs or PRUs that will be sold to satisfy applicable tax withholding obligations upon vesting is not currently determinable as the number will vary based on the market price of our common stock and the extent to which vesting conditions are satisfied. This sell-to-cover arrangement provides solely for the automatic sale of shares that would otherwise be issuable in respect of a covered RSU or PRU in an amount sufficient to satisfy the applicable withholding obligation, with the proceeds of the sale delivered to the Company in satisfaction of the applicable withholding obligation.
