On August 23, 2019, certain of the Reporting Persons entered into the following transactions:

Cactus Holding I amended and restated three previously disclosed variable prepaid forward contracts (“VPF”) covering 2,376,000, 5,044,308, and 3,331,003 shares, respectively. The amendment extended the maturity dates of the contracts to May 26, 2020 through May 28, 2020 for the 2,376,000 share and 3,331,003 share contracts, and to March 13, 2020 through March 17, 2020 for the 5,044,308 share contract. Previously, the maturity dates were August 30, 2019 through September 4, 2019. The new 2,376,000 share VPF is governed by that certain Sixth Amended and Restated Supplemental Confirmation, attached hereto as Exhibit 99.11. The new 5,044,308 share VPF is governed by that certain Fifth Amended and Restated May 2016 Supplemental Confirmation, attached hereto as Exhibit 99.12. The new 3,331,003 share VPF is governed by that certain Amended and Restated February 2019 Supplemental Confirmation, attached hereto as Exhibit 99.13.

M Capital II amended and restated its previously disclosed VPF covering 8,851,692 shares, terminated its previously disclosed VPF covering 9,864,000 shares, and entered into a new VPF covering 9,864,000 shares. The amendment extended the maturity dates to March 13, 2020 through April 9, 2020 for the 8,851,692 share contract. The new 9,864,000 share VPF contract has maturity dates from May 26, 2020 through June 22, 2020. Previously, the maturity dates for these VPFs were August 30, 2019 through September 27, 2019. M Capital II was entitled to receive $313,966,000 in connection with the new VPF, which was applied in partial satisfaction of the $332,568,000 required to terminate the existing VPF. The remaining $18,602,000 of the required termination payment was funded with a payment made by the counterparty for the benefit of M Capital II in respect of the Trigger Price Agreement discussed below. The new 8,851,692 share VPF is governed by that certain Fifth Amended and Restated Transaction 1 Supplemental Confirmation, attached hereto as Exhibit 99.14. The new 9,864,000 share VPF is governed by that certain Transaction 2 Supplemental Confirmation, attached hereto as Exhibit 99.15.

In addition to extending the maturity dates, the VPF amendments and new M Capital II VPF changed the applicable Forward Floor Prices and Forward Cap Prices set forth in the VPFs. Each of Cactus Holding I and M Capital II is generally permitted to participate in any appreciation of the Issuer’s Common Stock between the applicable Forward Floor Price and Forward Cap Price of the VPFs to which it is a party. The new Forward Floor Prices and Forward Cap Prices are $44.50 and $56.50, respectively, for the 8,851,692 share M Capital II VPF and the 5,044,308 share Cactus Holding I VPF, $42.50 and $52.95, respectively, for the 9,864,000 share M Capital II VPF and the 2,376,000 share Cactus Holding I VPF, and $42.00 and $52.25, respectively, for the 3,331,003 share Cactus I VPF.

In connection with these VPF transactions, M Capital II and Cactus Holding I entered into a Trigger Price Agreement, pursuant to which M Capital II and Cactus Holding I are obligated to make certain payments if the daily volume weighted average price of the Common Stock equals or exceeds a "Reset Trigger Price" and the VPFs can be terminated if the daily volume weighted average price of the Common Stock equals or exceeds an "Early Termination Price." Payments made under this agreement increase the Reset Trigger Price and Early Termination Price. The initial Reset Trigger Price is $36.75 and the initial Early Termination Price is $39.70. The amount of the required payments are determined by the counterparty in a commercially reasonable manner and using a consistent methodology as was used in determining the illustrative amounts provided to M Capital II and Cactus Holding I prior to entering into the Trigger Price Agreement. The Trigger Price Agreement is attached hereto as Exhibit 99.16.

No additional shares were pledged by the Reporting Persons in connection with the foregoing transactions. The purpose of the foregoing transactions was to extend the maturity of the aforementioned VPFs. The foregoing description of the VPF transactions is qualified in its entirety by reference to the text of these agreements, which are filed herewith as Exhibits 99.11 through 99.17.
