("Crestview III LP" and, together with Crestview III LLC, the "Crestview Entities") on February 28, 2022 in connection with the entry by an affiliate of the Crestview Entities into that certain Consent and Sixth Amendment to Senior Secured Term Loan Credit Agreement, dated February 28, 2022 (the "Credit Agreement Amendment") and the extension of a $10 million term loan by such affiliate to a subsidiary of the Issuer, and pursuant to the applicable Warrant Agreement (the "Warrant Agreement"). ( 2 )In accordance with the Warrant Agreement, the exercise price of the Warrants is $1.10 per share, subject to adjustment for stock splits, combinations, certain distributions or similar events in accordance with the terms of the Warrant Agreement. All or any portion of the Warrants issued pursuant to the Warrant Agreement may be exercised by the Crestview Entities at any time prior to expiration in accordance with the terms of the Warrant Agreement. The Warrants expire on February 28, 2028. ( 3 )Upon exercise by the Crestview Entities, pursuant to the Warrant Agreement, the Warrants are required to be net settled in shares of Class A Common Stock, on a cashless basis based on the difference between (i) the volume weighted average price of Class A Common Stock as reported during the ten trading day period ending on the second trading day prior to the date on which the notice of exercise is delivered to the warrant agent and (ii) the then-applicable exercise price, in each case, at the time of exercise. ( 4 )As a result, the number of shares of Class A Common Stock issuable upon exercise of the Warrants cannot be determined at this time; however, in no event will the Warrants be exercisable for more than 6,976,744 shares of Class A Common Stock (subject to adjustment for stock splits, combinations, certain distributions or similar events).
