(1) On October 9, 2020, a putative class action complaint was filed by two purported stockholders of the Issuer in the Court of Chancery of the State of Delaware under the caption Hollywood Firefighters' Pension Fund, et al. v. GCI Liberty, Inc., et al. On November 21, 2020, the plaintiffs and defendants in such lawsuit filed a stipulation and proposed order describing an agreement reached among them. As part of the agreement reached among the parties to the lawsuit, John C. Malone and the reporting person each agreed that he would convert each outstanding share of the Issuer's Series B common stock he beneficially owns immediately prior to the effective time of the Merger (as defined in the Remarks section) into one share of the Issuer's Series A common stock.
(2) Pursuant to the terms of the Merger Agreement (as defined in the Remarks section), each share of the Issuer's Series A common stock was converted into the right to receive 0.580 of a share of Parent's (as defined in the Remarks section) Series C common stock.
(3) Each share of the Issuer's Series B common stock is convertible, at the holder's election, into one share of the Issuer's Series A common stock at any time for no consideration other than the surrender of the share of Series B common stock for the share of Series A common stock.
(4) The number of shares reported as held in the reporting person's 401(k) is based on a statement from the Plan Administrator dated as of November 30, 2020, pro forma for the transactions contemplated by the Merger Agreement.
(5) The reporting person is the sole trustee of the grantor retained annuity trust, for the benefit of himself, his spouse and his children.
(6) The derivative security is fully vested.
(7) Pursuant to the terms of the Merger Agreement, each outstanding stock option to purchase shares of the Issuer's Series A common stock (an "original Series A stock option") was converted into 0.580 of a corresponding stock option to purchase shares of Parent's Series C common stock, rounded down to the nearest whole share. The exercise price of the original Series A stock option was divided by 0.580, with the resulting exercise price rounded up to the nearest cent. The stock options with respect to Parent's Series C common stock are subject to the same vesting, terms, restrictions and other conditions as those applicable to the corresponding original Series A stock option.
(8) Pursuant to the terms of the Merger Agreement, each outstanding stock option to purchase shares of the Issuer's Series B common stock (an "original Series B stock option") was converted into 0.580 of a corresponding stock option to purchase shares of Parent's Series B common stock, rounded down to the nearest whole share. The exercise price of the original Series B stock option was divided by 0.580, with the resulting exercise price rounded up to the nearest cent. The stock options with respect to Parent's Series B common stock are subject to the same vesting, terms, restrictions and other conditions as those applicable to the corresponding original Series B stock option.
