Explanation of Responses:

( 1 )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. ( 2 )These holdings were decreased by one share from the Form 4 filed by the reporting person on March 13, 2018 as the result of an accounting reconciliation. ( 3 )Pursuant to the terms of the Merger Agreement, each share of the Issuer's Series A Cumulative Redeemable Preferred Stock was converted into the right to receive 1 share of Parent's newly issued Series A Cumulative Redeemable Preferred Stock. ( 4 )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. ( 5 )Pursuant to the terms of the Merger Agreement, each share of the Issuer's Series B common stock was converted into the right to receive 0.580 of a share of Parent's Series B common stock. ( 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.

Remarks: On May 10, 2018, GCI Liberty, Inc., a Delaware corporation (previously known as GCI Merger Sub, Inc.), became the successor of GCI Liberty, Inc., an Alaska corporation, pursuant to a merger. The merger had the effect of changing GCI Liberty's domicile, but did not alter the proportionate interests of security holders. Pursuant to the Agreement and Plan of Merger, dated August 6, 2020 (the "Merger Agreement"), by and among the Issuer, Liberty Broadband Corporation ("Parent"), Grizzly Merger Sub 1, LLC, a Delaware limited liability company and a wholly owned subsidiary of Parent ("Merger LLC"), and Grizzly Merger Sub 2, Inc., a Delaware corporation and a wholly owned subsidiary of Merger LLC ("Merger Sub"), on December 18, 2020, Merger Sub merged with and into the Issuer (the "Merger"), with the Issuer surviving the Merger as a wholly owned subsidiary of Merger LLC, and immediately following the Merger, the Issuer (as the surviving corporation in the Merger) merged with and into Merger LLC (the "Upstream Merger"), with Merger LLC surviving the Upstream Merger as a wholly owned subsidiary of Parent.
