On August 3, 2021, Tellurian Inc. (the “Company”), in connection with a registered public offering of its common stock (the “Offering”), entered into an underwriting agreement (the “Underwriting Agreement”) with B. Riley Securities, Inc. (the “Underwriter”), pursuant to which the Company agreed to sell 35,000,000 shares of its common stock at a public offering price of $3.00 per share. Proceeds from the Offering, after deducting underwriting discounts and commissions and estimated fees and expenses, were approximately $100.7 million. In addition, pursuant to the Underwriting Agreement, the Underwriter was granted an option, exercisable within 30 days, to purchase up to an additional 5,250,000 shares of common stock to cover over-allotments, if any, on the same terms and conditions. The Underwriting Agreement contains customary representations, warranties and agreements by the Company and customary conditions to closing, obligations of the parties and termination provisions. Additionally, the Company has agreed to indemnify the Underwriters against certain liabilities, including liabilities under the Securities Act of 1933, as amended, or to contribute to payments the Underwriters may be required to make due to any such liabilities. The Offering was completed on August 6, 2021.

The legal opinion of Davis Graham & Stubbs LLP relating to the legality of the shares of common stock sold in the Offering is filed as Exhibit 5.1 to this Current Report on Form 8-K.

The representations, warranties and covenants contained in the Underwriting Agreement were made solely for purposes of the agreement and as of a specific date, were solely for the benefit of the parties to the agreement and may be subject to standards of materiality applicable to the contracting parties that differ from those applicable to security holders. Security holders should not rely on the representations, warranties, and covenants or any descriptions thereof as characterizations of the actual state of facts or condition of the Company.
