Ladies and Gentlemen:

        We have acted as counsel to Tellurian Inc., a Delaware corporation (the "Company"), in connection with the preparation of a Registration Statement on Form S-3 (the "Registration Statement") filed by the Company with the Securities and Exchange Commission (the "SEC") on or about the date hereof. The Registration Statement relates to the registration under the Securities Act of 1933, as amended (the "Securities Act"), of (i) shares of the Company's common stock, par value $0.01 per share (the "Common Stock"), (ii) shares of the Company's preferred stock, par value $0.01 per share (the "Preferred Stock"), (iii) warrants to purchase Common Stock or Preferred Stock (the "Warrants"), and (iv) units consisting of any combination of Common Stock, Preferred Stock, and Warrants (the "Units"). The Common Stock, Warrants, Units, and Preferred Stock are referred to collectively herein as the "Securities."

        The Securities may be issued and sold or delivered from time to time as set forth in the Registration Statement, any amendment thereto, the prospectus contained therein (the "Prospectus") and any supplement(s) to the Prospectus (a "Prospectus Supplement") pursuant to Rule 415 under the Securities Act.

        The Warrants may be issued under one or more warrant agreements (each, a "Warrant Agreement") between the Company and a counterparty or counterparties identified therein or a financial institution identified therein as the warrant agent (each, a "Warrant Counterparty"). The Units may be issued under one or more unit agreements (each, a "Unit Agreement"), each to be between the Company and a counterparty or counterparties identified therein (each, a "Unit Counterparty").

        In rendering the following opinion, we have examined originals or copies certified or otherwise identified to our satisfaction as being true copies, only of the following:

        In our examination, we have assumed the genuineness of all signatures, the authenticity, accuracy and completeness of the documents submitted to us as originals, and the conformity with the original documents of all documents submitted to us as copies. We have also assumed that (i) at the time of execution, countersignature, issuance, and delivery of the Warrants, the Warrant Agreement will be the valid and legally binding obligation of the Warrant Counterparty and (ii) at the time of execution, countersignature, issuance, and delivery of any Units, the Unit Agreement, if applicable, will be the valid and legally binding obligation of the Unit Counterparty.

        As to various questions of fact material to this opinion, we have relied, to the extent we deemed appropriate, upon representations or certificates of officers of the Company, without independently verifying the accuracy of such documents, records, and instruments.

        In connection with the issuance of the Warrants, we have assumed further that (i) at the time of execution, countersignature, issuance, and delivery of any Warrants, the related Warrant Agreement will have been duly authorized, executed, and delivered by the Company and (ii) execution, delivery and performance by the Company of such Warrant Agreement and such Warrants will not violate the laws of any jurisdiction.

        In connection with the issuance of the Units, we have assumed further that (i) at the time of execution, countersignature, issuance, and delivery of any Units, the related Unit Agreement will have been duly authorized, executed, and delivered by the Company, if applicable, and (ii) execution, delivery, and performance by the Company of such Unit Agreement, if applicable, and such Units will not violate the laws of any jurisdiction.

        The Securities may be issued from time to time on a delayed or continuous basis, and this opinion is limited to the laws, including the rules and regulations, as in effect on the date hereof, which laws are subject to change with possible retroactive effect.

        Based upon and subject to the limitations, qualifications, exceptions and assumptions set forth herein, we are of the opinion that:

        Insofar as this opinion relates to the validity, binding effect or enforceability of any agreement or obligation of the Company, it is subject to (i) applicable bankruptcy, insolvency, reorganization, moratorium, fraudulent transfer, fraudulent conveyance and similar laws affecting creditors' rights generally; (ii) the effects of general equitable principles, including, without limitation, concepts of materiality, reasonableness, good faith and fair dealing, and the possible unavailability of specific performance or injunctive relief, whether enforcement is considered in a proceeding in equity or law; (iii) the discretion of the court before which any proceeding for enforcement may be brought; (iv) the unenforceability of provisions that may be deemed contrary to public policy; (v) the rights or remedies available to any party for violations or breaches of any provisions of the Warrants or Units or related

agreements, as applicable, that are immaterial or the enforcement of which would be unreasonable under the then-existing circumstances; (vi) the rights or remedies available to any party for material violations or breaches that are the proximate result of actions taken by any party to the Warrants or Units or related agreements, as applicable, other than the party against whom enforcement is sought, which actions such other party is not entitled to take pursuant to the Warrants or Units or related agreements, as applicable, or that otherwise violate applicable laws; or (vii) the rights or remedies available to any party that takes discretionary action that is arbitrary, unreasonable or capricious, or is not taken in good faith or in a commercially reasonable manner, whether or not the Warrants or Units or related agreements, as applicable, permit such action.

        We are expressing no opinion as to any obligations that parties other than the Company may have under or in respect of the Securities covered by the Registration Statement or as to the effect that their performance of such obligations may have upon any of the matters referred to above.

        This opinion letter is limited to the matters stated herein and no opinions may be implied or inferred beyond the matters expressly stated herein. The opinions expressed herein are as of the date hereof, and we assume no obligation to update or supplement such opinions to reflect any facts or circumstances that may hereafter come to our attention or any changes in law that may hereafter occur.

        Our examination of matters of law in connection with the opinions expressed herein has been limited to, and accordingly our opinions herein are limited to, the Delaware General Corporation Law and the federal laws of the United States of America. We hereby consent to any reference to our firm in the Registration Statement and to the filing of this opinion as an exhibit to the aforesaid Registration Statement. In giving this consent, we do not thereby admit that we are in the category of persons whose consent is required under Section 7 of the Securities Act or the rules of the SEC.

  Very truly yours,
