(a) Intended to satisfy the affirmative defense of Rule 10b5-1(c) promulgated under the Securities Exchange Act of 1934, as amended (the "Exchange Act"). (b) Not intended to satisfy the affirmative defense of 10b5-1(c) promulgated under the Exchange Act. (c) The numbers in this column represent the maximum number of shares of our common stock that may be sold pursuant to each trading plan. (d) Transactions under the trading plan may occur during the specified plan duration period and will expire the earlier of the end of the specified plan duration period or the completion of all sales under such trading plan. (e) This number includes shares of our common stock issuable pursuant to unvested restricted stock unit awards ("RSUs") and unvested performance stock units ("PSUs"). The PSUs are subject to the achievement of certain performance conditions as set forth in the applicable PSU agreement. The actual number of PSUs that vest following the end of an applicable performance period, if any, vary and therefore the resulting shares of our common stock available for sale under the plan will depend on the attainment of the performance metrics. The maximum number of shares to be sold will be reduced by net shares withheld to satisfy tax withholding obligations that arise in connection with the vesting and settlement.
