Exhibit 7(t)

ASSIGNMENT AND ASSUMPTION AGREEMENT

THIS ASSIGNMENT AND ASSUMPTION AGREEMENT (this “Agreement”) dated as of March 9, 2018, is entered into by and among Liberty Broadband Corporation, a Delaware corporation (“Broadband”), Liberty Interactive Corporation, a Delaware corporation (“LIC”), LV Bridge, LLC, a Delaware limited liability company (“LV Bridge”), and GCI Liberty, Inc., an Alaska corporation (f/k/a General Communication, Inc.) (“Splitco”).

RECITALS

A. Broadband and LIC are parties to the Proxy and Right of First Refusal Agreement, dated as of May 23, 2015, as amended by Amendment No. 1 to Proxy and Right of First Refusal Agreement, dated May 13, 2016, by and among Broadband, LIC and LV Bridge (the “Proxy/ROFR Agreement”).

B. LIC, Liberty Interactive LLC, a Delaware limited liability company (“LI LLC”), and Splitco are parties to an Agreement and Plan of Reorganization dated as of April 4, 2017 (as amended pursuant to Amendment No. 1 to Reorganization Agreement, dated as of July 19, 2017, and Amendment No. 2 to Reorganization Agreement, dated as of November 8, 2017, and as may be further amended or supplemented, the “Reorganization Agreement”). In connection with the Reorganization Agreement, LIC adopted a restructuring plan (as such restructuring plan has been amended through the date of this Agreement, the “Restructuring Plan”).

C. Pursuant to the Reorganization Agreement and the Restructuring Plan: (i) LI LLC will transfer all of the ownership interests in LV Bridge, which holds all of the Covered Securities beneficially owned by LIC, to Ventures Holdco, LLC, which is currently a wholly-owned subsidiary of LI LLC; (ii) LI LLC will subsequently transfer all of the ownership interests in Ventures Holdco, LLC and other consideration to Splitco in exchange for stock of Splitco representing more than 80% of the voting power of Splitco and other consideration (the “Contribution”); and (iii) LIC will distribute its entire ownership interest in Splitco to the holders of LIC’s Liberty Ventures common stock in full redemption of all outstanding shares of such stock (the “Split-Off”).

D. The Split-Off is a LIC Distribution Transaction and Splitco is a LIC Qualified Distribution Transferee.

E. After giving effect to the transactions described in Recital C, Splitco will be the beneficial owner of the Covered Securities which are presently beneficially owned by LIC. LIC desires therefore to assign all of its rights and obligations under the Proxy/ROFR Agreement to Splitco, and Splitco desires to accept such rights and assume such obligations (the “Assignment and Assumption”).
