ABOUT TELLURIAN INC.

Tellurian plans to own, develop and operate natural gas liquefaction facilities, storage facilities and loading terminals (collectively, the “LNG Facilities”) and to pursue complementary business lines in the energy industry. Tellurian owns all of the common stock of Tellurian Investments Inc., a Delaware corporation (“Tellurian Investments”), which owns a 100% membership interest in Tellurian LNG LLC, a Delaware limited liability company (“Tellurian LNG”), a 100% membership interest in Tellurian Services LLC (f/k/a Parallax Services LLC), a Delaware limited liability company (“Tellurian Services”), and a 100% ownership interest in Tellurian LNG UK Ltd (“Tellurian UK”). The assets of Tellurian include its 100% ownership or membership interests in each of Tellurian Investments, Tellurian LNG, Tellurian Services and Tellurian UK, interests in Horse Hill-1 well and related licenses in the Weald Basin, onshore United Kingdom, an exploration block, NT/P82, in the Bonaparte Basin, offshore Northern Territory, Australia, and cash held for certain start-up and operating expenses.

Tellurian is planning on developing, through Tellurian LNG and Tellurian LNG’s wholly owned subsidiaries, a liquefied natural gas (“LNG”) facility with liquefaction capacity of 26 million tonnes per annum on a single site in Calcasieu Parish, Louisiana (the “Driftwood LNG Project”). Assuming approximately two years of permitting work and receipt of the appropriate regulatory approvals and financing commitments necessary to commence construction, followed by a four-year construction schedule, the Driftwood LNG Project could deliver its first LNG as soon as 2022. Tellurian also plans to pursue business that is complementary to its LNG business.

The Company was founded in 1957 and incorporated in Delaware in 1967 as Magellan Petroleum Corporation. We changed our corporate name to Tellurian Inc. shortly after completing a merger transaction with Tellurian Investments in February 2017. The Company’s common stock has been trading on the NASDAQ Stock Market since 1972. It currently trades under the ticker symbol “TELL.”

Our principal executive offices are located at 1201 Louisiana Street, Suite 3100, Houston, Texas 77002, and our telephone number is (832) 962-4000.

RISK FACTORS

Investing in our securities involves a high degree of risk. You should carefully consider the following risks, the risks set forth in the “Risk Factors” section of our Annual Report on Form 10-K for the fiscal year ended June 30, 2016, which is incorporated in this prospectus by reference, as well as the risk factors set forth in any applicable prospectus supplement and the other reports we file from time to time with the SEC that are incorporated by reference in this prospectus. If any of the events described in such “Risk Factors” disclosures occurs or such risks otherwise materialize, our business, financial condition, results of operations, cash flows, or prospects could be materially adversely affected.

Risks Relating to Tellurian’s Business

Tellurian does not expect Tellurian Investments to generate sufficient cash to pay dividends until the completion of construction of the Driftwood LNG Project by Tellurian LNG and its wholly owned subsidiaries.

Tellurian’s indirect ownership of 100% of the membership or ownership interests in each of Tellurian LNG, Tellurian Services LLC and Tellurian UK and cash held for certain start-up and operating expenses comprise substantially all of Tellurian’s assets. Tellurian’s cash flow and consequently its ability to distribute earnings is solely dependent upon the cash flow its subsidiaries receive from the Driftwood LNG Project and the transfer of funds in the form of distributions or otherwise. Tellurian LNG’s ability to complete the Driftwood LNG Project, as discussed further below, is dependent upon its, its subsidiaries and Tellurian Investments’ ability to obtain necessary regulatory approvals and raise the capital necessary to fund the development of the project.

Tellurian’s ability to pay dividends in the future is uncertain and will depend on a variety of factors including limitations on the ability of it or its subsidiaries to pay dividends under applicable law and/or the terms of debt or other agreements, and the judgment of the board of directors or other governing body of the relevant entity.

In addition, because Tellurian Investments’ business will have limited asset and geographic diversification, adverse developments in the natural gas and LNG industry, or to the Driftwood LNG Project, will have a greater impact on Tellurian Investments’ financial condition than if it maintained a more diverse asset and geographic profile.

Tellurian will be required to seek additional debt and equity financing in the future to complete the Driftwood LNG Project, and may not be able to secure such financing on acceptable terms, or at all.

Because Tellurian will be unable to generate any revenue from its operations and expects to be in the development stage for multiple years, Tellurian will need additional financing to provide the capital required to execute its business plan. Tellurian will need significant funding to develop the Driftwood LNG Project as well as for working capital requirements and other operating and general corporate purposes.

There can be no assurance that Tellurian will be able to raise sufficient capital on acceptable terms, or at all. If such financing is not available on satisfactory terms, or is not available at all, Tellurian may be required to delay, scale back or eliminate the development of business opportunities, and its operations and financial condition may be adversely affected to a significant extent.

Table of Contents

Debt financing, if obtained, may involve agreements that include liens on its assets and covenants limiting or restricting the ability to take specific actions, such as paying dividends or making distributions, incurring additional debt, acquiring or disposing of assets and increasing expenses. Debt financing would also be required to be repaid regardless of Tellurian’s operating results.

In addition, the ability to obtain financing for the proposed Driftwood LNG Project is expected to be contingent upon, among other things, Tellurian’s ability to enter into sufficient long-term commercial agreements prior to the commencement of construction. To date, Tellurian has not entered into any definitive third-party agreements for the proposed Driftwood LNG Project, and it may not be successful in negotiating and entering into such agreements.

Tellurian Investments and Tellurian LNG have a limited operating history.

Both Tellurian Investments and Tellurian LNG were formed in 2016, and only recently commenced development. Although Tellurian’s current directors, managers and officers have prior professional and industry experience, Tellurian Investments and Tellurian LNG have a limited prior operating history, track record and historical financial information upon which you may evaluate prospects.

Tellurian LNG has not yet commenced the construction of the Driftwood LNG Project. Accordingly, Tellurian expects to incur significant additional costs and expenses through completion of development and construction of the Driftwood LNG Project. As a result, Tellurian expects operating losses will increase substantially in the remainder of 2016 and thereafter, and expects to continue to incur operating losses and experience negative operating cash flow through at least 2022.

Failure to retain and attract key executive officers and other skilled professional and technical employees could have an adverse effect on Tellurian’s business, results of operations, financial condition, liquidity and prospects.

The success of Tellurian’s business relies heavily on its executive officers. Should Tellurian’s executive officers be unable to perform their duties on behalf of Tellurian, or should Tellurian be unable to retain or attract other members of management, Tellurian’s business, results of operations, financial condition, liquidity and prospects could be materially impacted.

Tellurian will be subject to risks related to doing business in, and having counterparties based in, foreign countries.

Tellurian may engage in operations or make substantial commitments and investments, or enter into agreements with counterparties, located outside the United States, which would expose Tellurian to political, governmental, and economic instability and foreign currency exchange rate fluctuations.

Any disruption caused by these factors could harm Tellurian’s business, results of operations, financial condition, liquidity and prospects. Risks associated with operations, commitments and investments outside of the United States include but are not limited to risks of:

5

Table of Contents

Because Tellurian’s reporting currency is the United States dollar, any of the operations conducted outside the United States or denominated in foreign currencies would face additional risks of fluctuating currency values and exchange rates, hard currency shortages and controls on currency exchange. In addition, Tellurian would be subject to the impact of foreign currency fluctuations and exchange rate changes on its financial reports when translating its assets, liabilities, revenues and expenses from operations outside of the United States into U.S. dollars at then-applicable exchange rates. These translations could result in changes to the results of operations from period to period.

Tellurian Investments is currently classified as a United States real property holding company (“USRPHC”) under applicable tax laws, and non-U.S. investors may be subject to tax withholding and other tax consequences upon a disposition of their shares.

Tellurian Investments is a USRPHC under applicable tax laws, which subjects non-U.S. investors to tax withholding and other tax consequences upon a disposition of their shares. Tellurian will likely be classified in the same manner, which subjects non-U.S. investors to tax withholding and other tax consequences upon a disposition of their Tellurian shares. Non-U.S. investors should consult their tax advisors with respect to the application of this to their investment and other U.S. tax rules.

Tellurian Investments is a defendant in a lawsuit that could result in equitable relief and/or monetary damages that could have a material adverse effect on Tellurian’s operating results and financial condition.

Tellurian Investments and Tellurian Services, along with each of Messrs. Houston and Daniels and certain entities in which each of them owned membership interests, as applicable, have been named as defendants in one recently initiated lawsuit. Although Tellurian Investments believes the plaintiffs’ claims are without merit, Tellurian Investments may not ultimately be successful and any potential liability Tellurian Investments may incur is not reasonably estimable. However, even if Tellurian Investments is successful in the defense of this litigation, Tellurian Investments could incur costs and suffer both an economic loss and an adverse impact on its reputation, which could have a material adverse effect on its business. In addition, any adverse judgment or settlement of the litigation could have an adverse effect on its operating results and financial condition.

Table of Contents

Tellurian’s estimated costs for the Driftwood LNG Project may not be accurate and are subject to change due to various factors.

Tellurian currently estimates that the construction costs for the Driftwood LNG Project will be between approximately $13 billion and $15 billion. However, cost estimates are only an approximation of the actual costs of construction and are before owners’ costs, financing costs, pipeline construction costs and contingencies. Moreover, cost estimates may change due to various factors, such as the final terms of any definitive request for services with its engineering, procurement and construction (“EPC”) service provider, as well as change orders, delays in construction, legal and regulatory requirements, site issues, increased component and material costs, escalation of labor costs, labor disputes, increased spending to maintain Tellurian’s construction schedule and other factors.

The construction and operation of the Driftwood LNG Project remains subject to further approvals, and some approvals may be subject to further conditions, review and/or revocation.

The design, construction and operation of LNG export terminals is a highly regulated activity. The approval of the U.S. Federal Energy Regulatory Commission (“FERC”) under Section 3 of the Natural Gas Act, as well as several other material governmental and regulatory approvals and permits, is required in order to construct and operate an LNG terminal. Although the necessary authorizations to operate the proposed LNG Facilities may be obtained, such authorizations are subject to ongoing conditions imposed by regulatory agencies, and additional approval and permit requirements may be imposed.

Tellurian will be required to obtain governmental approvals and authorizations to implement its proposed business strategy, which includes the construction and operation of the Driftwood LNG Project. In particular, authorization from FERC and the U.S. Department of Energy is required to construct and operate the proposed LNG Facilities. In addition to seeking approval for export to countries with which the United States has a Free Trade Agreement (“FTA”), Tellurian will seek to obtain approval for export to non-FTA countries. There is no assurance that Tellurian will obtain and maintain these governmental permits, approvals and authorizations, and failure to obtain and maintain any of these permits, approvals or authorizations could have a material adverse effect on its business, results of operations, financial condition and prospects.

Tellurian will be dependent on third-party contractors for the successful completion of the Driftwood LNG Project, and these contractors may be unable to complete the Driftwood LNG Project.

There is limited recent industry experience in the United States regarding the construction or operation of large-scale liquefaction facilities. The construction of the Driftwood LNG Project is expected to take several years, will be confined to a limited geographic area and could be subject to delays, cost overruns, labor disputes and other factors that could adversely affect financial performance or impair Tellurian’s ability to execute its scheduled business plan.

Timely and cost-effective completion of the Driftwood LNG Project in compliance with agreed-upon specifications will be highly dependent upon the performance of third-party contractors pursuant to their agreements. However, Tellurian has not yet entered into definitive agreements with certain of the contractors, advisors and consultants necessary for the development and construction of the Driftwood LNG Project. Tellurian may not be able to successfully enter into such construction contracts on terms or at prices that are acceptable to it.

Table of Contents

Further, faulty construction that does not conform to Tellurian’s design and quality standards may have an adverse effect on Tellurian’s business, results of operations, financial condition and prospects. For example, improper equipment installation may lead to a shortened life of Tellurian’s equipment, increased operations and maintenance costs or a reduced availability or production capacity of the affected facility. The ability of Tellurian’s third-party contractors to perform successfully under any agreements to be entered into is dependent on a number of factors, including force majeure events and such contractors’ ability to:

Furthermore, Tellurian may have disagreements with its third-party contractors about different elements of the construction process, which could lead to the assertion of rights and remedies under the related contracts, resulting in a contractor’s unwillingness to perform further work on the relevant project. Tellurian may also face difficulties in commissioning a newly constructed facility. Any significant project delays in the development of the Driftwood LNG Project could materially and adversely affect Tellurian’s business, results of operations, financial condition and prospects.

Tellurian’s ability to generate cash is substantially dependent upon it entering into contracts with third parties and the performance of those customers under those contracts.

Tellurian has not yet entered into, and may never be able to enter into, satisfactory commercial arrangements with third-party customers for products and services at the Driftwood LNG Project.

Tellurian’s business strategy may change regarding how and when the proposed Driftwood LNG Project’s export capacity is marketed. Also, Tellurian’s business strategy may change due to the inability to enter into agreements with customers or based on views regarding future prices, supply and demand of LNG, natural gas liquefaction capacity, and worldwide regasification capacity. If the efforts to market the proposed Driftwood LNG Project are not successful, Tellurian’s business, results of operations, financial condition and prospects may be materially and adversely affected.

Table of Contents

Tellurian LNG’s construction and operations activities are subject to a number of development risks, operational hazards, regulatory approvals and other risks, which could cause cost overruns and delays and could have a material adverse effect on its business, results of operations, financial condition, liquidity and prospects.

Siting, development and construction of the Driftwood LNG Project will be subject to the risks of delay or cost overruns inherent in any construction project resulting from numerous factors, including, but not limited to, the following:

Delays beyond the estimated development periods, as well as cost overruns, could increase the cost of completion beyond the amounts that are currently estimated, which could require Tellurian to obtain additional sources of financing to fund the activities until the proposed Driftwood LNG Project is constructed and operational (which could cause further delays). Any delay in completion of the Driftwood LNG Project may also cause a delay in the receipt of revenues projected from the Driftwood LNG Project or cause a loss of one or more customers. As a result, any significant construction delay, whatever the cause, could have a material adverse effect on Tellurian’s business, results of operations, financial condition, liquidity and prospects.

Table of Contents

Technological innovation may render Tellurian’s anticipated competitive advantage or its processes obsolete.

Tellurian’s success will depend on its ability to create and maintain a competitive position in the natural gas liquefaction industry. In particular, although Tellurian plans to construct the Driftwood LNG Project using proven technologies that it believes provides it with certain advantages, Tellurian does not have any exclusive rights to any of the technologies that it will be utilizing. In addition, the technology Tellurian anticipates using in the Driftwood LNG Project may be rendered obsolete or uneconomical by legal or regulatory requirements, technological advances, more efficient and cost-effective processes or entirely different approaches developed by one or more of its competitors or others, which could materially and adversely affect Tellurian’s business, results of operations, financial condition, liquidity and prospects.

Decreases in the demand for and price of natural gas could lead to reduced development of LNG projects worldwide.

Tellurian is subject to risks associated with the development, operation and financing of domestic LNG facilities. The development of domestic LNG facilities and projects are generally based on assumptions about the future price of natural gas and LNG and the conditions of the global natural gas and LNG markets. Natural gas and LNG prices have been, and are likely to remain in the future, volatile and subject to wide fluctuations that are difficult to predict. Such fluctuations may be caused by factors such as the competitive liquefaction capacity in North America; the international supply and receiving capacity of LNG; LNG tanker capacity; weather conditions; domestic and global demand for natural gas; the effect of government regulation on the production, transportation and sale of natural gas; oil and natural gas exploration and production activities; the development of and changes in the cost of alternative energy sources for natural gas and political and economic conditions worldwide.

Further, the development of liquefaction facilities takes a substantial amount of time, requires significant capital investment, may be delayed by unforeseen and uncontrollable factors and is dependent on the financial viability and ability of Tellurian to market LNG internationally.

Competition in the liquefied natural gas industry is intense, and some of Tellurian’s competitors have greater financial, technological and other resources.

Tellurian plans to operate in the highly competitive area of liquefied natural gas production and faces intense competition from independent, technology-driven companies as well as from both major and other independent oil and natural gas companies and utilities.

Many competing companies have secured access to, or are pursuing development or acquisition of, LNG facilities to serve the North American natural gas market, including other proposed liquefaction facilities in North America. Tellurian may face competition from major energy companies and others in pursuing its proposed business strategy to provide liquefaction and export products and services at its proposed Driftwood LNG Project. In addition, competitors have and are developing additional LNG terminals in other markets, which also compete with the proposed LNG Facilities. Almost all of these competitors have longer operating histories, more development experience, greater name recognition, larger staffs and substantially greater financial, technical and marketing resources than Tellurian currently possesses. The superior resources that these competitors have available for deployment could allow them to compete successfully against Tellurian, which could have a material adverse effect on Tellurian’s business, results of operations, financial condition, liquidity and prospects.

10

Table of Contents

There may be shortages of LNG vessels worldwide, which could have a material adverse effect on Tellurian’s business, results of operations, financial condition, liquidity and prospects.

The construction and delivery of LNG vessels requires significant capital and long construction lead times, and the availability of the vessels could be delayed to the detriment of Tellurian’s business and customers due to the following:

A terrorist or military incident involving an LNG carrier could result in delays in, or cancellation of, construction or closure of the proposed LNG Facilities.

A terrorist or military incident involving an LNG carrier may result in delays in, or cancellation of, construction of new LNG facilities, including the proposed LNG Facilities, which would increase Tellurian’s costs and decrease cash flows. A terrorist incident may also result in temporary or permanent closure of Tellurian’s proposed LNG Facilities, including the Driftwood LNG Project, which could increase costs and decrease cash flows, depending on the duration of the closure. Operations at the proposed LNG Facilities, including the Driftwood LNG Project, could also become subject to increased governmental scrutiny that may result in additional security measures at a significant incremental cost. In addition, the threat of terrorism and the impact of military campaigns may lead to continued volatility in prices for natural gas that could adversely affect Tellurian’s business and customers, including the ability of Tellurian’s suppliers or customers to satisfy their respective obligations under Tellurian’s commercial agreements.

Changes in legislation and regulations relating to the LNG industry could have a material adverse impact on Tellurian’s business, results of operations, financial condition, liquidity and prospects.

Future legislation and regulations, such as those relating to the transportation and security of LNG exported from the proposed LNG Facilities through the Calcasieu Ship Channel, could cause additional expenditures, restrictions and delays in connection with the proposed LNG Facilities and their construction, the extent of which cannot be predicted and which may require Tellurian to limit substantially, delay or cease operations in some circumstances. Revised, reinterpreted or additional laws and regulations that result in increased compliance costs or additional operating costs and restrictions could have a material adverse effect on Tellurian’s business, results of operations, financial condition, liquidity and prospects.

11

Table of Contents

Tellurian’s operations will be subject to a number of environmental laws and regulations that impose significant compliance costs, and existing and future environmental and similar laws and regulations could result in increased compliance costs or additional operating restrictions.

Tellurian’s business will be subject to extensive federal, state and local regulations and laws, including regulations and restrictions on discharges and releases to the air, land and water and the handling, storage and disposal of hazardous materials and wastes in connection with the development, construction and operation of its liquefaction facilities. These regulations and laws will require Tellurian to maintain permits, provide governmental authorities with access to its facilities for inspection and provide reports related to its compliance. Violation of these laws and regulations could lead to substantial fines and penalties or to capital expenditures related to pollution control equipment that could have a material adverse effect on Tellurian’s business, results of operations, financial condition, liquidity and prospects. Federal and state laws impose liability, without regard to fault or the lawfulness of the original conduct, for the release of certain types or quantities of hazardous substances into the environment. As the owner and operator of the Driftwood LNG Project, Tellurian could be liable for the costs of cleaning up hazardous substances released into the environment and for damage to natural resources.

In addition, future federal, state and local legislation and regulations may impose unforeseen burdens and increased costs on Tellurian’s business that could have a material adverse effect on Tellurian’s financial results, such as regulations regarding greenhouse gas emissions and the transportation of LNG.

The operation of the proposed Driftwood LNG Project may be subject to significant operating hazards and uninsured risks, one or more of which may create significant liabilities and losses that could have a material adverse effect on Tellurian’s business, results of operations, financial condition, liquidity and prospects.

The plan of operations for the proposed Driftwood LNG Project is subject to the inherent risks associated with LNG operations, including explosions, pollution, release of toxic substances, fires, hurricanes and other adverse weather conditions, and other hazards, each of which could result in significant delays in commencement or interruptions of operations and/or result in damage to or destruction of the proposed Driftwood LNG Project and assets or damage to persons and property. In addition, operations at the proposed Driftwood LNG Project and vessels of third parties on which Tellurian’s operations are dependent face possible risks associated with acts of aggression or terrorism.

Tellurian does not, nor does it intend to, maintain insurance against all of these risks and losses. Tellurian may not be able to maintain desired or required insurance in the future at rates that it considers reasonable. The occurrence of a significant event not fully insured or indemnified against could have a material adverse effect on Tellurian’s business, contracts, financial condition, operating results, cash flow, liquidity and prospects.

Financial projections by Tellurian Investments may not prove to be reflective of actual future results.

Agreement, upon the closing of the merger with Tellurian Investments on February 10, 2017, we issued 409,800 shares of our common stock to Petrie as compensation for advisory services provided by Petrie in connection with the merger.

On September 30, 2016, we entered into a Purchase and Sale Agreement with the former owners of Nautilus Technical Group, LLC and Eastern Rider LLC, each formerly a Colorado limited liability Company, a group comprised of JTWI Corporation, a Colorado corporation, Pebcor Enterprises, LLC, a Colorado limited liability company, Monty Hoffman, George Mainzer, Terry Ross, Naing Aye, and Wayne W.

PLAN OF DISTRIBUTION

The selling stockholders may offer and sell shares of our common stock from time to time using this prospectus. We will not receive any of the proceeds of the sales of these shares.

The selling stockholders may offer and sell shares directly to purchasers using this prospectus. The selling stockholders may donate, pledge or otherwise transfer in a non-sale related transaction its shares to any person so long as the transfer complies with applicable securities laws. As a result, donees, pledgees, transferees and other successors in interest that receive such shares as a gift, distribution or other non-sale related transfer may offer shares of common stock under this prospectus.

The selling stockholders may from time to time offer shares through brokers, dealers, agents or underwriters. Brokers, dealers, agents or underwriters participating in transactions may receive compensation in the form of discounts, concessions or commissions from the selling stockholders (and, if they act as agent for the purchaser of the shares, from that purchaser). Any brokerage commissions, underwriting discounts and similar selling expenses attributable to the sale of shares covered by this prospectus by the selling stockholders will be borne by them. We will bear the other costs, fees and expenses incurred in connection with the registration of the offering of securities under this prospectus.

Any brokers, dealers or agents who participate in the distribution of the shares by the selling stockholders may be deemed to be underwriters, and any profits on the sale of shares by them and any discounts, commissions or concessions received by any broker, dealer or agent may be deemed underwriting discounts and commissions under the Securities Act.

A prospectus supplement or document incorporated by reference may be filed to disclose additional information with respect to any sale or other distribution of the shares.

The selling stockholders may act independently of us in making decisions with respect to the timing, manner and size of each sale. Sales may be made on the NASDAQ Capital Market or any other national securities exchange or quotation service on which the securities may be listed or quoted at the time of sale.

The shares may be sold according to any one or more of the methods described above. In addition, subject to compliance with applicable law, the selling stockholders may enter into option, derivative or hedging transactions with respect to the shares, and any related offers or sales of shares may be made under this prospectus. In some circumstances, for example, the selling stockholders may write call options, put options or other derivative instruments (including exchange-traded options or privately negotiated options) with respect to the shares, or which they settle through delivery of the shares. These option, derivative and hedging transactions may require the delivery to a broker, dealer or other financial institution of shares offered under this prospectus, and that broker, dealer or other

16

Table of Contents

financial institution may resell those shares under this prospectus. The selling stockholders may offer and sell the shares under any other method permitted by applicable law.

If a material arrangement with any broker-dealer or other agent is entered into for the sale of any shares of common stock through a block trade, special offering, exchange distribution, secondary distribution, or a purchase by a broker or dealer, a prospectus supplement will be filed, if necessary, disclosing the material terms and conditions of these arrangements.

The selling stockholders may also sell their shares in accordance with Rule 144 under the Securities Act, or pursuant to other available exemptions from the registration requirements of the Securities Act, rather than pursuant to this prospectus.

The selling stockholders may agree to indemnify any underwriter, broker, dealer or agent that participates in transactions involving sales of the shares against certain liabilities, including liabilities arising under the Securities Act.

Anti-Takeover Provisions of Delaware Law

We are subject to the anti-takeover provisions of Section 203 of the DGCL. In general, Section 203 prohibits a publicly held Delaware corporation from engaging in a “business combination” with an “interested stockholder” for a period of three years after the date of the transaction in which the person became an interested stockholder, unless the business combination is approved in a prescribed manner.

Section 203 defines a “business combination” as a merger, asset sale, or other transaction resulting in a financial benefit to the interested stockholder. Section 203 defines an “interested stockholder” as a person who, together with affiliates and associates, owns, or, in some cases, within the three prior years, did own, 15% or more of the corporation’s voting stock. Under Section 203, a business combination between us and an interested stockholder is subject to the three-year moratorium unless:

Table of Contents

These provisions may have an anti-takeover effect with respect to transactions not approved in advance by our board of directors, including by discouraging takeover attempts that might result in a premium over the market price for the shares of our stock. With approval of our stockholders, we could amend our certificate of incorporation in the future to elect not to be governed by these anti-takeover provisions.

If legal matters in connection with offerings made under this prospectus are acted on by counsel for the underwriters, dealers or agents, if any, that counsel will be named in the applicable prospectus supplement to the extent required.

EXPERTS

Tellurian Inc. was formerly known as Magellan Petroleum Corporation; it changed its name to Tellurian Inc. shortly after the completion of the merger contemplated by that certain Agreement and Plan of Merger, dated as of August 2, 2016, by and among Magellan Petroleum Corporation, Tellurian Investments and River Merger Sub, Inc., a Delaware corporation. As a result of the merger, Tellurian Investments became a subsidiary of Magellan Petroleum Corporation. However, the managements of those entities determined that Tellurian Investments was the “accounting acquirer” in the transaction for purposes of Financial Accounting Standards Board’s Accounting Standards Codification 805, Business Combinations. Accordingly, the financial statements of Tellurian Services, LLC, the predecessor of Tellurian Investments, are considered under applicable SEC guidance to be the financial statements of the registrant. Certain historical information of Magellan Petroleum Corporation is also included in this prospectus supplement as noted below.

Item 17.  Undertakings.

(a)        The undersigned registrant hereby undertakes:

(1)        To file, during any period in which offers or sales are being made, a post-effective amendment to this registration statement:

(i)        To include any prospectus required by Section 10(a)(3) of the Securities Act of 1933;

(ii)        To reflect in the prospectus any facts or events arising after the effective date of the registration statement (or the most recent post-effective amendment thereof) which, individually or in the aggregate, represent a fundamental change in the information set forth in the registration statement. Notwithstanding the foregoing, any increase or decrease in volume of securities offered (if the total dollar

II-2

Table of Contents

value of securities offered would not exceed that which was registered) and any deviation from the low or high end of the estimated maximum offering range may be reflected in the form of prospectus filed with the SEC pursuant to Rule 424(b) if, in the aggregate, the changes in volume and price represent no more than a 20% change in the maximum aggregate offering price set forth in the “Calculation of Registration Fee” table in the effective registration statement; and

(iii)        To include any material information with respect to the plan of distribution not previously disclosed in the registration statement or any material change to such information in the registration statement;

Provided, however, that:

Paragraphs (1)(i), (ii), and (iii) above do not apply if the information required to be included in a post-effective amendment by those paragraphs is contained in reports filed with or furnished to the SEC by the registrant pursuant to Section 13 or Section 15(d) of the Securities Exchange Act of 1934 that are incorporated by reference in the registration statement, or is contained in a form of prospectus filed pursuant to Rule 424(b) that is part of the registration statement.

(2)        That, for the purpose of determining any liability under the Securities Act of 1933, each such post-effective amendment shall be deemed to be a new registration statement relating to the securities offered therein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof.

(3)        To remove from registration by means of a post-effective amendment any of the securities being registered which remain unsold at the termination of the offering.

(4)        That, for the purpose of determining liability under the Securities Act of 1933 to any purchaser:

(i)        Each prospectus filed by the registrant pursuant to Rule 424(b)(3) shall be deemed to be part of the registration statement as of the date the filed prospectus was deemed part of and included in the registration statement; and

(ii)        Each prospectus required to be filed pursuant to Rule 424(b)(2), (b)(5), or (b)(7) as part of a registration statement in reliance on Rule 430B relating to an offering made pursuant to Rule 415(a)(1)(i), (vii), or (x) for the purpose of providing the information required by Section 10(a) of the Securities Act of 1933 shall be deemed to be part of and included in the registration statement as of the earlier of the date such form of prospectus is first used after effectiveness or the date of the first contract of sale of securities in the offering described in the prospectus. As provided in Rule 430B, for liability purposes of the issuer and any person that is at that date an underwriter, such date shall be deemed to be a new effective date of the registration statement relating to the securities in the registration statement to which the prospectus relates, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof. Provided, however, that no statement made in a registration statement or prospectus that is part of the registration statement or made in a document

II-3

Table of Contents

incorporated or deemed incorporated by reference into the registration statement or prospectus that is part of the registration statement will, as to a purchaser with a time of contract of sale prior to such effective date, supersede or modify any statement that was made in the registration statement or prospectus that was part of the registration statement or made in any such document immediately prior to such effective date.

(b)        The undersigned registrant hereby undertakes that, for purposes of determining any liability under the Securities Act of 1933, each filing of the registrant’s annual report pursuant to Section 13(a) or Section 15(d) of the Securities Exchange Act of 1934 (and, where applicable, each filing of an employee benefit plan’s annual report pursuant to Section 15(d) of the Securities Exchange Act of 1934) that is incorporated by reference in the registration statement shall be deemed to be a new registration statement relating to the securities offered therein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof.

(c)        Insofar as indemnification for liabilities arising under the Securities Act of 1933 may be permitted to directors, officers, and controlling persons of the registrant pursuant to the foregoing provisions, or otherwise, the registrant has been advised that in the opinion of the SEC such indemnification is against public policy as expressed in the Securities Act of 1933 and is, therefore, unenforceable. In the event that a claim for indemnification against such liabilities (other than the payment by the registrant of expenses incurred or paid by a director, officer, or controlling person of the registrant in the successful defense of any action, suit, or proceeding) is asserted by such director, officer, or controlling person in connection with the securities being registered, the registrant will, unless in the opinion of its counsel the matter has been settled by controlling precedent, submit to a court of appropriate jurisdiction the question of whether such indemnification by it is against public policy as expressed in the Securities Act of 1933 and will be governed by the final adjudication of such issue.
