TABLE OF CONTENTS

PROSPECTUS SUPPLEMENT SUMMARY

This summary highlights certain information contained elsewhere in this prospectus supplement, the accompanying base prospectus and in the documents we incorporate by reference. This summary is not complete and does not contain all of the information that you should consider before investing in our securities. You should read this entire prospectus supplement, the accompanying base prospectus and any related free writing prospectus carefully, including the information referred to in the section entitled “Risk Factors” beginning on page S-7 of this prospectus supplement, as well as the other documents that we incorporate by reference into this prospectus supplement and the accompanying base prospectus, including our financial statements and the exhibits to the registration statement of which this prospectus supplement and the accompanying base prospectus is a part.

Our Business

We intend to create value for shareholders by building a low-cost, global natural gas business, profitably delivering natural gas to customers worldwide (the “Business”). We are developing a portfolio of natural gas, LNG marketing, and infrastructure assets that includes an LNG terminal facility (the “Driftwood terminal”) and related pipelines (the “Pipeline Network”). We refer to the Driftwood terminal, the Pipeline Network and required natural gas assets collectively as the “Driftwood Project.” Our existing natural gas assets consist of 9,704 net acres and interests in 72 producing wells located in the Haynesville Shale trend of northern Louisiana. Our Business may be developed in phases.

As part of our execution strategy, we will consider partnering with third parties across the natural gas value chain. We are also pursuing activities such as direct sales of LNG to global counterparties, the acquisition of additional upstream acreage, the drilling of new wells on our existing or newly acquired upstream acreage and trading LNG. As discussed in “Recent Developments” below, we have recently entered into LNG sale and purchase agreements with three purchasers, completing the planned sales for plants one and two of the Driftwood Project (“Phase 1”). We are currently focused on financing the construction of Phase 1.

We continue to evaluate, and discuss with potential partners, the scope and other aspects of our Business in light of the evolving economic environment, needs of potential partners and other factors. How we execute our Business will be based on a variety of factors, including the results of our continuing analysis, changing business conditions and market feedback.

Recent Developments

We recently entered into 10-year LNG sale and purchase agreements with three purchasers covering an aggregate of 9.0 million tonnes per annum of LNG, with prices linked to the Japan Korea Market (“JKM”) and Dutch Transfer Title Facility (“TTF”) indexes, netted back for transportation charges. The LNG would be delivered free on board from the Driftwood Project. Based on JKM and TTF one-year strip prices quoted by S&P Global Platts and Intercontinental Exchange, Inc., respectively, as of July 30, 2021, the agreements with the three purchasers represent an aggregate of $50 billion in estimated revenue over their ten-year terms. We are in discussions with other potential purchasers of LNG from the Driftwood Project.

Our Company

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 Inc., a Delaware corporation, in February 2017. Our 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. We maintain a website at http://www.tellurianinc.com. The information contained in, or that can be accessed through, our website is not part of this prospectus supplement, and you should not consider any information contained on, or that can be accessed through, our website as part of this prospectus supplement or in deciding whether to purchase our common stock in this offering.

TABLE OF CONTENTS

RISK FACTORS

Investing in our securities involves a high degree of risk. You should carefully consider the risks set forth in the “Risk Factors” sections of the documents that we incorporate by reference into this prospectus supplement and the accompanying base 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 Related to Our Business

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

Tellurian will be unable to generate any significant revenue from the Driftwood Project for multiple years, and expects cash flow from its other lines of business to be modest for an extended period as it focuses on the development and growth of these businesses. Tellurian will, therefore, need substantial amounts of additional financing to execute its business plan. 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 cancel the development of business opportunities, and this could adversely affect its operations and financial condition to a significant extent. Tellurian intends to pursue a variety of potential financing transactions, and we do not know whether, and to what extent, potential sources of financing will find the terms we propose acceptable. In addition, potential sources of financing may conclude that the terms of our commercial agreements are not attractive enough to justify an investment. In addition, debt or preferred equity financing, if obtained, may involve agreements that include liens or restrictions on Tellurian’s assets and covenants limiting or restricting our ability to take specific actions, such as paying dividends or making distributions, incurring additional debt, acquiring or disposing of assets or increasing expenses. Debt financing would also be required to be repaid regardless of Tellurian’s operating results. Obtaining financing through additional issuances of common stock would impose fewer restrictions on our future operations but would be dilutive to the interests of existing stockholders.

Cyclical or other changes in the demand for and price of LNG and natural gas may adversely affect Tellurian’s LNG business and the performance of our customers and could lead to the reduced development of LNG projects worldwide.

Tellurian’s plans and expectations regarding its business and 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 various factors, including, but not limited to, one or more of the following:

•

competitive liquefaction capacity in North America;

•

insufficient or oversupply of natural gas liquefaction or receiving capacity worldwide;

•

insufficient or oversupply of LNG tanker capacity;

•

weather conditions;

•

reduced demand and lower prices for natural gas, including as a result of the COVID-19 pandemic or similar events and related economic disruptions;

•

increased natural gas production deliverable by pipelines, which could suppress demand for LNG;

•

decreased oil and natural gas exploration activities, which may decrease the production of natural gas;

•

cost improvements that allow competitors to offer LNG regasification services or provide natural gas liquefaction capabilities at reduced prices;

S-7

TABLE OF CONTENTS

•

changes in supplies of, and prices for, alternative energy sources such as coal, oil, nuclear, hydroelectric, wind and solar energy, which may reduce the demand for natural gas;

•

changes in regulatory, tax or other governmental policies regarding imported or exported LNG, natural gas or alternative energy sources, which may reduce the demand for imported or exported LNG and/or natural gas;

•

political conditions in natural gas producing regions; and

•

cyclical trends in general business and economic conditions that cause changes in the demand for natural gas.

Adverse trends or developments affecting any of these factors could result in decreases in the price of LNG and/or natural gas, which could materially and adversely affect the performance of our customers and could have a material adverse effect on our business, contracts, financial condition, operating results, cash flows, liquidity and prospects. The revenue assumptions for the LNG sale agreements discussed in “Summary — Recent Developments” are based on current market prices; actual prices, and therefore revenues actually received, will vary. The profitability of those agreements for us will depend in part on the relationship between the costs we incur in producing or purchasing natural gas and the then-current index prices when sales occur. An adverse change in that relationship, whether resulting from an increase in our costs, a decline in the index prices or both, could make sales under the agreements less profitable or could require us to sell at a loss.

Risks Related to this Offering

Resales of our common stock in the public market following this offering may cause the trading price to fall.

Resales of a substantial number of shares of our common stock could depress the trading price of our common stock. This offering of new shares of our common stock could result in resales of our common stock by our current stockholders concerned about the potential dilution of their holdings. If our stockholders sell substantial amounts of our common stock in the public market following the offering contemplated by this prospectus supplement, the trading price of our common stock could fall.

If you purchase our common stock in the public market following this offering, you will experience immediate dilution as a result of future equity issuances.

Because the price per share of our common stock being offered may be higher than the book value per share of our common stock, you may suffer immediate and substantial dilution in the net tangible book value of the common stock you purchase in this offering. The issuance of additional shares of our common stock in future offerings could be dilutive to stockholders if they do not invest in future offerings. Moreover, to the extent that we issue options or warrants to purchase, or securities convertible into or exchangeable for, shares of our common stock in the future and those options, warrants or other securities are exercised, converted or exchanged, stockholders may experience further dilution.

We have broad discretion in the use of the net proceeds of the offering of our common stock contemplated by this prospectus supplement and, despite our efforts, we may use such proceeds in a manner that does not improve our operating results or increase the value of your investment.

We currently anticipate that the net proceeds from the offering of our common stock contemplated by this prospectus supplement will be used as described in “Use of Proceeds.” However, we have not determined the specific use of the net proceeds from the offering of our common stock contemplated by this prospectus supplement. Our management will have broad discretion over the use and investment of those funds, and, accordingly, investors will need to rely upon the judgment of our management with respect to the use of such proceeds, with only limited information concerning our specific intentions. These proceeds could be applied in ways that do not improve our operating results or increase the value of your investment.

Non-U.S. holders of our common stock, in certain situations, could be subject to U.S. federal income tax upon sale, exchange or disposition of our common stock.

It is possible that we may become a U.S. real property holding corporation (a “USRPHC”) for U.S. federal income tax purposes if it is determined, at any time, that the fair market value of our assets that

S-8

TABLE OF CONTENTS

consist of “United States real property interests,” as defined in the Internal Revenue Code of 1986, as amended (the “Code”), and applicable Treasury regulations, constitute at least 50% of the combined fair market value of our real estate interests and other business assets. If we were a USRPHC, then under the Foreign Investment in Real Property Tax Act, or FIRPTA, certain non-U.S. investors could be subject to U.S. federal income tax on any gain from the disposition of shares of our common stock, in which case they would also be required to file U.S. tax returns with respect to such gain. In general, whether these FIRPTA provisions apply in such case would depend on the amount of our common stock that such non-U.S. investors hold. In addition, such non-U.S. investors could be subject to withholding in such case if, at the time they dispose of their shares, our common stock is not regularly traded on an established securities market within the meaning of the applicable Treasury regulations. Even if we were a USRPHC, so long as our common stock continues to be regularly traded on an established securities market, only a non-U.S. investor who has owned, actually or constructively, more than 5% of our common stock at any time during the shorter of (i) the five-year period ending on the date of disposition and (ii) the non-U.S. investor’s holding period for its shares may be subject to U.S. federal income tax on the disposition of our common stock under FIRPTA. See “Material United States Federal Income Tax Considerations to Non-U.S. Holders.”

In particular, this discussion does not address the U.S. federal income tax consequences of ownership of our common stock by investors that do not hold the stock as a capital asset within the meaning of Section 1221 of the Code, or the U.S. federal income tax consequences to beneficial owners subject to special treatment under the U.S. federal income tax laws, such as:

•

dealers in securities or currencies;

•

certain electing traders in securities;

•

persons holding our common stock as part of a conversion, constructive sale, wash sale or other integrated transaction or a straddle or synthetic security;

pass-through entities, including partnerships and entities and arrangements classified as partnerships for U.S. federal tax purposes, and beneficial owners of pass-through entities.

Non-U.S. holders subject to the special circumstances described above may be subject to tax rules that differ significantly from those summarized below, and such holders should consult their own tax advisors to determine the U.S. federal income tax consequences that may be relevant to them. In addition, this summary does not include any non-U.S. tax laws or state or local tax laws that may be applicable to a particular investor and does not consider any aspects of U.S. federal estate or gift tax law. Non-U.S. holders should consult their tax advisors as to these matters.

You are a “non-U.S. holder” of our common stock if you are a beneficial owner of the stock and are not, for U.S. federal income tax purposes:

•

an individual who is a citizen or resident of the United States;

•

a corporation (or other entity treated as a corporation for U.S. federal income tax purposes) organized or created in or under the laws of the United States, any state thereof or the District of Columbia;

•

an estate, the income of which is subject to U.S. federal income tax regardless of the source of such income; or

•

a trust (i) if a court within the U.S. is able to exercise primary supervision over its administration and one or more United States persons (within the meaning of Section 7701(a)(30) of the Code) (“U.S. persons”) have the authority to control all of the substantial decisions of the trust, or (ii) that has a valid election in place to be treated as a U.S. person for U.S. federal income tax purposes.

If an entity or arrangement treated as a partnership for U.S. federal income tax purposes holds our common stock, the tax consequences of such partnership and the partners in such partnership generally

S-12

TABLE OF CONTENTS

will depend on the status of each of the partners and the activities of the partnership. Partners of partnerships considering the purchase of our common stock are encouraged to consult with their independent tax advisors.

This summary is based upon the Code, existing and proposed Treasury regulations promulgated thereunder, administrative pronouncements and judicial decisions, all in effect as of the date hereof, all of which are subject to change, possibly on a retroactive basis. Such a change could affect the continuing validity of this discussion and may adversely affect a non-U.S. holder. There can be no assurance that the Internal Revenue Service, or the IRS, will not challenge one or more of the conclusions described herein, and we have not obtained, and do not intend to obtain, a ruling from the IRS with respect to the U.S. federal income tax consequences of purchasing, owning and disposing of our common stock.

IF YOU ARE CONSIDERING THE PURCHASE OF OUR COMMON STOCK, YOU ARE ENCOURAGED TO CONSULT WITH AN INDEPENDENT TAX ADVISOR REGARDING THE APPLICATION OF U.S. FEDERAL INCOME AND ESTATE TAX LAWS, AS WELL AS OTHER U.S. FEDERAL TAX LAWS AND THE LAWS OF ANY STATE, LOCAL OR NON-U.S. TAXING JURISDICTION, TO YOUR PARTICULAR SITUATION. THIS DISCUSSION OF U.S. FEDERAL TAX CONSIDERATIONS IS FOR GENERAL INFORMATION ONLY AND IS NOT TAX ADVICE.

Dividend Distributions

Any distributions with respect to the shares of our common stock, to the extent paid out of our current or accumulated earnings and profits (as determined under U.S. federal income tax principles), will constitute dividends for U.S. federal income tax purposes and will be subject to U.S. federal withholding tax at a 30% rate or such lower rate as specified by an applicable income tax treaty, provided that such dividends are not effectively connected with the non-U.S. holder’s conduct of a U.S. trade or business (and, if required by an applicable income tax treaty, are attributable to a U.S. “permanent establishment” maintained by such non-U.S. holder). Distributions in excess of our current and accumulated earnings and profits (as determined under U.S. federal income tax principles) will first constitute a return of capital that is applied against and reduces the non-U.S. holder’s adjusted tax basis in our common stock (determined on a share by share basis), and, to the extent such distribution exceeds the non-U.S. holder’s adjusted tax basis, the excess will be treated as gain realized on the sale or other disposition of our common stock as described below under “Sale, Exchange or Other Taxable Disposition of Stock.” Any such distributions will also be subject to the rules, regulations and obligations discussed below under the heading “Foreign Accounts.”

Under the terms of an applicable U.S. income tax treaty (if any), the withholding tax might not apply, or might apply at a reduced rate. A non-U.S. holder who wishes to claim the benefit of an applicable income tax treaty is required to satisfy applicable certification and disclosure requirements (generally by providing our paying agent or a relevant withholding agent with an IRS Form W-8BEN or IRS Form W-8BEN-E). If a non-U.S. holder is eligible for a reduced rate of U.S. withholding tax pursuant to an income tax treaty, such non-U.S. holder may obtain a refund or credit of any excess amounts withheld by timely filing an appropriate claim for refund with the IRS.

Dividends that are effectively connected with the conduct of a non-U.S. holder’s trade or business within the United States (and, if required by an applicable income tax treaty, are attributable to a U.S. “permanent establishment” maintained by such non-U.S. holder) are not subject to U.S. federal withholding tax if such non-U.S. holder provides our paying agent or a relevant withholding agent with an IRS Form W-8ECI, but generally will be subject to U.S. federal income tax on a net-income basis at applicable graduated individual or corporate rates, unless an applicable income tax treaty provides otherwise. A foreign corporation may be subject to an additional branch profits tax (at a 30% rate or such lower rate as specified by an applicable income tax treaty) on its effectively connected earnings and profits attributable to such income.

Sale, Exchange or Other Taxable Disposition of Stock

Subject to the discussions below under “Information Reporting and Backup Withholding” and “Foreign Accounts,” any gain realized by a non-U.S. holder upon the sale, exchange or other taxable disposition of shares of our common stock generally will not be subject to U.S. federal income tax unless:

S-13

TABLE OF CONTENTS

•

that gain is effectively connected with the non-U.S. holder’s conduct of a trade or business in the United States (and, if required by an applicable income tax treaty, is attributable to a U.S. “permanent establishment” maintained by the non-U.S. holder);

•

the non-U.S. holder is a nonresident alien individual who is present in the United States for 183 days or more in the taxable year of that disposition, and certain other conditions are met; or

•

we are or have been a United States real property holding corporation (a “USRPHC”) for U.S. federal income tax purposes at any time during the shorter of (i) the five-year period ending on the date of disposition and (ii) the non-U.S. holder’s holding period for its shares of our common stock and, if shares of our common stock are “regularly traded on an established securities market,” the non-U.S. holder held, directly or indirectly, at any time during such period, more than 5% of our issued and outstanding common stock.

Gain described in the first bullet point above will be subject to U.S. federal income tax in the same manner as that of a U.S. person, unless an applicable income tax treaty provides otherwise. If such non-U.S. holder is a foreign corporation, such gain may also be subject to a branch profits tax (at a 30% rate or such lower rate as specified by an applicable income tax treaty) on its effectively connected earnings and profits attributable to such income. A non-U.S. holder described in the second bullet point above will be subject to a 30% U.S. federal income tax on the gain derived from the sale, which may be offset by certain U.S.-source capital losses.

Regarding the third bullet, it is possible that we may become a USRPHC for U.S. federal income tax purposes. If we were a USRPHC, then so long as our common stock continued to be regularly traded on an established securities market within the meaning of the applicable Treasury regulations, only a non-U.S. holder who held more than 5% of our common stock at any time during the shorter of (i) its holding period and (ii) the five-year period preceding the date of disposition (a “greater-than-five-percent shareholder”) would be subject to U.S. federal income tax on the disposition of our common stock. In such case, a greater-than-five-percent shareholder generally would be subject to U.S. federal income tax on the net gain derived from the sale in the same manner as a U.S. person, unless an applicable income tax treaty provides otherwise. Such a non-U.S. holder generally would be required to file a U.S. federal income tax return in respect of such gain. No withholding would be required upon any sale or other taxable disposition of our common stock if it is regularly traded on an established securities market. If we were a USRPHC and our common stock ceased to be regularly traded on an established securities market, a non-U.S. holder would be subject to tax on any gain recognized on the sale or other taxable disposition of our common stock, and withholding, generally at a rate of 15%, on the gross proceeds thereof, regardless of such non-U.S. holder’s percentage ownership of our common stock.

Information Reporting and Backup Withholding

We and other withholding agents must report annually to the IRS the amount of dividends or other distributions paid to non-U.S. holders on shares of our common stock and the amount of tax we and other withholding agents withhold on these distributions. Copies of the information returns reporting such distributions and any withholding may also be made available to the tax authorities in the country in which the non-U.S. holder resides, under the provisions of an applicable income tax treaty.

A non-U.S. holder will not be subject to backup withholding (the current rate of which is 24%) on reportable payments the non-U.S. holder receives on shares of our common stock if the non-U.S. holder provides proper certification (usually on an IRS Form W-8BEN or IRS Form W-8BEN-E) of its status as a non-U.S. person.

Information reporting and backup withholding generally are not required with respect to the amount of any proceeds from the sale or other disposition of shares of our common stock outside the United States through a foreign office of a foreign broker that does not have certain specified connections to the United States. However, information reporting will apply if a non-U.S. holder sells shares of our common stock outside the United States through a U.S. broker or a broker that is a controlled foreign corporation, a foreign person that derives 50% or more of its gross income for certain periods from the conduct of a trade or business in the United States, or a foreign partnership that, at any time during its tax year, either is engaged

S-14

TABLE OF CONTENTS

in the conduct of a trade or business in the United States or has as partners one or more U.S. persons that, in the aggregate, hold more than 50% of the income or capital interests in the partnership. If a sale or other disposition is made through a U.S. office of any broker, the broker will be required to report to the IRS the amount of proceeds paid to the non-U.S. holder and to backup withhold on that amount unless the non-U.S. holder provides appropriate certification (usually on an IRS Form W-8BEN or IRS Form W-8BEN-E) to the broker certifying the non-U.S. holder’s status as a non-U.S. person or other exempt status.

Any amounts withheld under the backup withholding rules will generally be allowed as a refund or a credit against a non-U.S. holder’s U.S. federal income tax liability, provided the required information is properly furnished to the IRS on a timely basis.

Foreign Accounts

Sections 1471 through 1474 of the Code (commonly referred to as “FATCA”) generally impose a 30% withholding tax on “withholdable payments,” which include dividends on our common stock and gross proceeds from the disposition of our common stock paid to (i) a foreign financial institution (as defined in Section 1471 of the Code) unless it agrees to collect and disclose to the IRS information regarding direct and indirect U.S. account holders and (ii) a non-financial foreign entity unless it certifies certain information regarding substantial U.S. owners of the entity, which generally includes any U.S. person who directly or indirectly owns more than 10% of the entity. Foreign financial institutions located in jurisdictions that have an intergovernmental agreement with the United States governing FATCA may be subject to different rules. Under U.S. Treasury regulations and IRS guidance, the withholding obligations described above apply to payments of dividends on our common stock. While these withholding obligations would also apply to payments of gross proceeds from a sale or other disposition of our common stock, recently proposed Treasury regulations, which state that taxpayers may rely on the proposed regulations until final regulations are issued, eliminate this requirement. Prospective non-U.S. holders should consult their own tax advisors with respect to the potential tax consequences of FATCA.

Proceeds, before expenses, to us

We estimate that the total expenses of this offering, including registration, filing and listing fees, printing fees and legal and accounting expenses, but excluding underwriting discounts and commissions, will be approximately $100,000.

We have agreed that we will not offer, sell, contract to sell, pledge or otherwise dispose of, directly or indirectly, or file with the SEC a registration statement under the Securities Act relating to, any shares of our common stock or securities convertible into or exchangeable or exercisable for any shares of our common stock, or publicly disclose the intention to make any offer, sale, pledge, disposition or filing, without the prior written consent of B.

Our executive officers and directors have agreed that they will not offer, sell, contract to sell, pledge or otherwise dispose of, directly or indirectly, any shares of our common stock or securities convertible into or exchangeable or exercisable for any shares of our common stock, enter into a transaction that would have the same effect, or enter into any swap, hedge or other arrangement that transfers, in whole or in part, any of the economic consequences of ownership of our common stock, whether any of these transactions are to be settled by delivery of our common stock or other securities, in cash or otherwise, or publicly disclose the

S-16

intention to make any offer, sale, pledge or disposition, or to enter into any transaction, swap, hedge or other arrangement with similar effect, without, in each case, the prior written consent of B. Riley Securities, Inc. for a period of 60 days after the date of this prospectus supplement, provided that each of our executive officers and directors, may, without the written consent of B. Riley Securities, Inc., (i) effect the cashless exercise or net share settlement of options to acquire shares of our common stock or other awards granted pursuant to an equity incentive plan in effect on the date hereof, it being understood that any shares of our common stock received by such person upon such exercise shall be subject to a lock-up agreement, and provided that, if such person reports any such transfer or other disposition on a Form 4 filed with the SEC pursuant to Section 16 of the Exchange Act in reliance on this clause (i), then such Form 4 shall include a statement to the effect that such transfer or other disposition was made solely to effect the cashless exercise or net share settlement of options to acquire shares of our common stock or other awards granted pursuant to an equity incentive plan, (ii) transfer to us any shares of our common stock or have us withhold any shares of our common stock from issuance for purposes of satisfying any tax withholding obligation that arises in connection with the vesting of such awards, provided that, if such person reports any such transfer or other disposition on a Form 4 filed with the SEC pursuant to Section 16 of the Exchange Act in reliance on this clause (ii), then such Form 4 shall include a statement to the effect that such transfer or other disposition was made to us solely to permit such person to satisfy the tax withholding obligation that arises in connection with the vesting of an award granted under one of our company equity incentive plans, (iii) transfer shares of our common stock under a trading plan pursuant to Rule 10b5-1 under the Exchange Act that was in effect prior to the date of the underwriting agreement (not including any amendment thereto after the date of the underwriting agreement) and (iv) establish a trading plan pursuant to Rule 10b5-1 under the Exchange Act for the transfer of shares of our common stock, provided that such plan does not provide for any transfers of shares of our common stock during the lock-up period and provided further that no filing with the SEC or other public announcement shall be required or voluntarily made by the such person or any other person in connection therewith.

We have agreed to indemnify the underwriter against liabilities under the Securities Act, or contribute to payments that the underwriter may be required to make in that respect.

The shares of common stock are listed on the Nasdaq Capital Market under the ticker symbol “TELL.”

The underwriter and its affiliates are full-service financial institutions engaged in various activities, which may include sales and trading, commercial and investment banking, advisory, investment management, investment research, principal investment, hedging, market making, brokerage and other financial and non-financial activities and services. The underwriter and its affiliates have provided, and may in the future provide, a variety of these services to us and to persons and entities with relationships with us, for which they received or will receive customary fees and expenses.

In the ordinary course of their various business activities, the underwriter and its affiliates, officers, directors and employees may purchase, sell or hold a broad array of investments and actively traded securities, derivatives, loans, commodities, currencies, credit default swaps and other financial instruments for their own account and for the accounts of their customers, and such investment and trading activities may involve or relate to our assets, securities and/or instruments (directly, as collateral securing other obligations or otherwise) and/or persons and entities with relationships with us. The underwriter and its affiliates may also communicate independent investment recommendations, market color or trading ideas and/or publish or express independent research views in respect of such assets, securities or instruments and may at any time hold, or recommend to clients that they should acquire, long and/or short positions in such assets, securities and instruments.

In connection with the offering, the underwriter may engage in stabilizing transactions, over-allotment transactions and covering transactions in accordance with Regulation M under the Exchange Act.

•

Stabilizing transactions permit bids to purchase the underlying security so long as the stabilizing bids do not exceed a specified maximum.

•

An over-allotment involves sales by the underwriter of shares in excess of the number of shares the underwriter is obligated to purchase, which creates a short position. The short position may be either a covered short position or a naked short position. In a covered short position, the number of

S-17

TABLE OF CONTENTS

shares over-allotted by the underwriter is not greater than the number of additional shares that it has the option to purchase. In a naked short position, the number of shares involved is greater than the number of additional shares that they have the option to purchase. The underwriter may close out any covered short position by either exercising its option to purchase additional shares and/or purchasing shares in the open market.

•

Covering transactions involve purchases of the common stock in the open market after the distribution has been completed in order to cover short positions. In determining the source of shares to close out the short position, the underwriter will consider, among other things, the price of shares available for purchase in the open market as compared to the price at which it may purchase additional shares through its option to purchase such shares. If the underwriter sells more shares than could be covered by its option to purchase additional shares, a naked short position, the position can only be closed out by buying shares in the open market. A naked short position is more likely to be created if the underwriter is concerned that there could be downward pressure on the price of the shares in the open market after pricing that could adversely affect investors who purchase shares in the offering.

These stabilizing transactions and covering transactions may have the effect of raising or maintaining the market price of our common stock or preventing or retarding a decline in the market price of the common stock. As a result, the price of our common stock may be higher than the price that might otherwise exist in the open market. These transactions may be effected on the Nasdaq Capital Market or otherwise and, if commenced, may be discontinued at any time.

A prospectus in electronic format may be made available on the website maintained by the underwriter participating in this offering, and the underwriter participating in this offering may distribute prospectuses electronically.

provided that no such offer of common stock referred to in (a) to (c) above shall result in a requirement for the Company or the representative to publish a prospectus pursuant to Article 3 of the Prospectus Directive, or supplement a prospectus pursuant to Article 16 of the Prospectus Directive.

Each person located in a Member State to whom any offer of common stock is made or who receives any communication in respect of an offer of common stock, or who initially acquires any common stock will be deemed to have represented, warranted, acknowledged and agreed to and with the representative and the Company that (1) it is a “qualified investor” within the meaning of the law in that Member State implementing Article 2(1)(e) of the Prospectus Directive; and (2) in the case of any common stock acquired by it as a financial intermediary as that term is used in Article 3(2) of the Prospectus Directive, the common stock acquired by it in the offer has not been acquired on behalf of, nor has it been acquired with a view to its offer or resale to, persons in any Member State other than qualified investors, as that term is defined in the Prospectus Directive, or in circumstances in which the prior consent of the representative has been given to the offer or resale; or where common stock has been acquired by it on behalf of persons in any Member State other than qualified investors, the offer of that common stock to it is not treated under the Prospectus Directive as having been made to such persons.

The Company, the underwriter and their respective affiliates will rely upon the truth and accuracy of the foregoing representations, acknowledgments and agreements.

This prospectus supplement has been prepared on the basis that any offer of shares in any Member State will be made pursuant to an exemption under the Prospectus Directive from the requirement to publish a prospectus for offers of shares.

Neither the Company nor the underwriter has authorized, nor do they authorize, the making of any offer of shares in circumstances in which an obligation arises for the Company or the underwriter to publish a prospectus for such offer.

For the purposes of this provision, the expression an “offer of common stock to the public” in relation to any common stock in any Member State means the communication in any form and by any means of sufficient information on the terms of the offer and the common stock to be offered so as to enable an investor to decide to purchase or subscribe the common stock, as the same may be varied in that Member State by any measure implementing the Prospectus Directive in that Member State, and the expression “Prospectus Directive” means Directive 2003/71/EC (as amended) and includes any relevant implementing measure in each Member State.

The above selling restriction is in addition to any other selling restrictions set out below or above.

TABLE OF CONTENTS

ABOUT TELLURIAN INC.

We intend to create value for shareholders by building a low-cost, global natural gas business, profitably delivering natural gas to customers worldwide (the “Business”). We are developing a portfolio of natural gas production, liquefied natural gas (“LNG”) marketing, and infrastructure assets that includes an LNG terminal facility (the “Driftwood terminal”) and three related pipelines (the “Pipeline Network”). We refer to the Driftwood terminal, the Pipeline Network and certain natural gas production assets collectively as the “Driftwood Project.” We currently estimate the total cost of the Driftwood Project to be approximately $28.9 billion, including owners’ costs, transaction costs and contingencies but excluding interest costs incurred during construction of the Driftwood terminal and other financing costs. Our Business may be developed in phases.

The proposed Driftwood terminal will have a liquefaction capacity of approximately 27.6 million tonnes per annum and will be situated on approximately 1,000 acres in Calcasieu Parish, Louisiana. The proposed Driftwood terminal will include up to 20 liquefaction trains, three full containment LNG storage tanks and three marine berths. We have entered into four lump sum turnkey engineering, procurement and construction agreements totaling $15.5 billion with Bechtel Oil, Gas and Chemicals, Inc. (“Bechtel”) for construction of the Driftwood terminal.

The proposed Pipeline Network is currently expected to consist of three pipelines, the Driftwood pipeline, the Haynesville Global Access Pipeline and the Permian Global Access Pipeline. The Driftwood pipeline will be a 96-mile large diameter pipeline that will interconnect with 14 existing interstate pipelines throughout southwest Louisiana to secure adequate natural gas feedstock for the Driftwood terminal. The Driftwood pipeline will be comprised of 48-inch, 42-inch and 36-inch diameter pipeline segments and three compressor stations totaling approximately 274,000 horsepower, all as necessary to provide approximately 4 billion cubic feet per day (“Bcf/d”) of average daily natural gas transportation service. We estimate construction costs for the Driftwood pipeline of up to approximately $2.3 billion before owners’ costs, financing costs and contingencies.

The Haynesville Global Access Pipeline is expected to run approximately 200 miles from northern to southwest Louisiana. The Permian Global Access Pipeline is expected to run approximately 625 miles from west Texas to southwest Louisiana. Each of these pipelines is expected to have a diameter of 42 inches and be capable of delivering approximately 2 Bcf/d of natural gas. We currently estimate that construction costs will be approximately $1.4 billion for the Haynesville Global Access Pipeline and approximately $4.2 billion for the Permian Global Access Pipeline, in each case before owners’ costs, financing costs and contingencies. We are also considering the potential development of a fourth pipeline, the Delhi Connector Pipeline, which would run approximately 180 miles from Perryville/Delhi in northeast Louisiana to Lake Charles, Louisiana.

Our upstream properties, acquired in a series of transactions during 2017 and 2018, consist of 10,260 net acres and 67 producing wells (21 operated) located in the Haynesville Shale trend of northern Louisiana.

In connection with the implementation of our Business, we are offering limited partnership interests in a subsidiary, Driftwood Holdings LP (“Driftwood Holdings”), which will own the Driftwood Project. Partners will contribute cash in exchange for equity in Driftwood Holdings and will receive LNG volumes at the cost of production, including the cost of debt, for the life of the Driftwood terminal. We plan to retain a portion of the ownership in Driftwood Holdings and have engaged Goldman Sachs & Co. and Société Générale to serve as financial advisors for Driftwood Holdings. We also continue to develop our LNG marketing activities.

RISK FACTORS

Investing in our securities involves a high degree of risk. You should carefully consider the risks set forth in the “Risk Factors” section of our Annual Report on Form 10-K for the fiscal year ended December 31, 2019, 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.

Resales of our common stock in the public market following an offering may cause the trading price to fall.

Resales of a substantial number of shares of our common stock could depress the trading price of our common stock. An offering of new shares of our common stock could result in resales of our common stock by our current stockholders concerned about the potential dilution of their holdings. If our stockholders sell substantial amounts of our common stock in the public market following an offering, the trading price of our common stock could fall.

If you purchase our common stock in an offering, you may experience immediate dilution.

Because the price per share of our common stock being offered may be higher than the book value per share of our common stock, you may suffer immediate and substantial dilution in the net tangible book value of the common stock you purchase in an offering. The issuance of additional shares of our common stock in future offerings could be dilutive to stockholders if they do not invest in future offerings. Moreover, to the extent that we issue options or warrants to purchase, or securities convertible into or exchangeable for, shares of our common stock in the future and those options, warrants or other securities are exercised, converted or exchanged, stockholders may experience further dilution.

Pandemics or disease outbreaks, such as the currently ongoing COVID-19 outbreak, may adversely affect our efforts to reach a final investment decision with respect to the Driftwood Project.

Pandemics or disease outbreaks such as the currently ongoing COVID-19 outbreak may have a variety of adverse effects on our business, including by depressing commodity prices and the market value of our securities and limiting the ability of our management to travel to meet with partners and potential partners. Prospects for the development and financing of the Driftwood Project are based in part on factors including global economic conditions that have been, and are likely to continue to be, adversely affected by the COVID-19 pandemic. Additional effects of the pandemic on our business may include limits on the ability of our employees, or those of partners or vendors, to provide necessary services due to illness or quarantines and governmental restrictions on travel, imports or exports or financial transactions.

USE OF PROCEEDS

Unless a prospectus supplement indicates otherwise, the net proceeds we receive from the sale of the securities offered by this prospectus will be used for general corporate purposes. Pending the application of

TABLE OF CONTENTS

the net proceeds from any particular offering, we intend to invest such proceeds in short- and intermediate-term, interest-bearing obligations, investment-grade instruments, certificates of deposit or direct or guaranteed obligations of the U.S. government.

Each time we issue securities, we will provide a prospectus supplement that will contain information about how we intend to use the proceeds from each such offering. We will bear all of the expenses of the offering of the securities, and such expenses will be paid out of our general funds, unless otherwise stated in the applicable prospectus supplement.

We cannot guarantee that we will receive any proceeds in connection with any offering hereunder because we may choose not to issue any of the securities covered by this prospectus.

PLAN OF DISTRIBUTION

We may sell securities under this prospectus and any relevant prospectus supplement to or through underwriters or dealers, directly to other purchasers or through agents. In addition, we may from time to time sell securities through a bidding or auction process, block trades, ordinary brokerage transactions or transactions in which a broker solicits purchasers. We may also use a combination of any of the foregoing methods of sale. We may distribute the securities from time to time in one or more transactions at a fixed price or prices (which may be changed from time to time), at market prices prevailing at the times of sale, at prices related to these prevailing market prices or at negotiated prices. We may offer securities in the same offering or in separate offerings. From time to time, we may exchange securities for indebtedness or other securities that we may have outstanding. In some cases, dealers acting for us may also purchase securities and re-offer them to the public by one or more of the methods described above.

Any person participating in the distribution of common stock registered under the Registration Statement that includes this prospectus will be subject to applicable provisions of the Exchange Act and applicable SEC rules and regulations, including, among others, Regulation M, which may limit the timing of purchases and sales of any of our common stock by any such person. Furthermore, Regulation M may restrict the ability of any person engaged in the distribution of our common stock to engage in market-making activities with respect to our common stock. These restrictions may affect the marketability of our common stock and the ability of any person or entity to engage in market-making activities with respect to our common stock.

Certain persons participating in an offering may engage in over-allotment, stabilizing transactions, short-covering transactions and penalty bids in accordance with Regulation M under the Exchange Act that stabilize, maintain or otherwise affect the price of the offered securities. If any such activities may occur, they will be described in the applicable prospectus supplement or a document incorporated by reference to the extent required.

Offering

We will provide required disclosure concerning the terms of the offering of the securities in a prospectus supplement or information incorporated by reference, including, to the extent applicable:

•

the name or names of underwriters, dealers or agents;

•

the purchase price of the securities and the proceeds we will receive from the sale;

•

any underwriting discounts, commissions, and other items constituting underwriters’ compensation;

•

any over-allotment options under which underwriters may purchase additional securities from us;

•

any commissions paid to agents;

•

any discounts or concessions allowed or reallowed or paid to dealers; and

•

any securities exchange or market on which the securities may be listed.

The distribution of securities may be effected, from time to time, in one or more transactions, including:

•

underwritten offerings;

TABLE OF CONTENTS

•

block transactions (which may involve crosses) and transactions on the Nasdaq Capital Market or any other organized market where the securities may be traded;

•

purchases by a broker-dealer as principal and resale by the broker-dealer for its own account;

•

ordinary brokerage transactions and transactions in which a broker-dealer solicits purchasers;

•

sales “at the market” to or through a market maker or into an existing trading market, on an exchange or otherwise;

•

sales in other ways not involving market makers or established trading markets, including direct sales to purchasers through registered direct offerings or otherwise; and

•

any other method permitted pursuant to applicable law.

Dealers and agents participating in the distribution of the securities may be deemed to be underwriters, and compensation received by them on resale of the securities may be deemed to be underwriting discounts and commissions under the Securities Act. If such dealers or agents were deemed to be underwriters, they may be subject to statutory liabilities under the Securities Act. Unless otherwise indicated, any agent will be acting on a best efforts basis for the period of its appointment.

If underwriters are used in an offering, securities will be acquired by the underwriters for their own account and may be resold, from time to time, in one or more transactions, including negotiated transactions, at a fixed public offering price or at varying prices determined at the time of sale, or under delayed delivery contracts or other contractual commitments. Securities may be offered to the public either through underwriting syndicates represented by one or more managing underwriters or directly by one or more firms acting as underwriters. If an underwriter or underwriters are used in the sale of securities, an underwriting agreement will be executed with the underwriter or underwriters at the time an agreement for the sale is reached. The applicable prospectus supplement will set forth the managing underwriter or underwriters, as well as any other underwriter or underwriters, with respect to a particular underwritten offering of securities, and will set forth the terms of the transactions, including compensation of the underwriters and dealers and the public offering price, if applicable.

If a dealer is used in the sale of the securities, we or an underwriter will sell the securities to the dealer as principal. The dealer may then resell the securities to the public at varying prices to be determined by the dealer at the time of resale.

We may directly solicit offers to purchase the securities and may make sales of securities directly to institutional investors or others. These persons may be deemed to be underwriters within the meaning of the Securities Act with respect to any resale of the securities. To the extent required, the prospectus supplement or document incorporated by reference, as applicable, will describe the terms of any such sales, including the terms of any bidding or auction process, if used.

Underwriters, dealers and agents may be entitled under agreements that may be entered into with us to indemnification by us against specified liabilities, including liabilities incurred under the Securities Act, or to contribution by us to payments they may be required to make in respect of such liabilities. If required, the prospectus supplement or document incorporated by reference, as applicable, will describe the terms and conditions of such indemnification or contribution. Some of the agents, underwriters or dealers, or their affiliates, may be customers of, engage in transactions with or perform services for us, our subsidiaries or affiliates in the ordinary course of business.

In addition, we may enter into derivative transactions with third parties, in which case the third parties may sell securities covered by this prospectus and the applicable prospectus supplement or incorporated document and received by those parties in settlement of a derivative position.

To the extent required, this prospectus will be amended or supplemented from time to time to describe a specific plan of distribution.

Other than common stock, all securities sold under this prospectus will be new issues of securities with no established trading market. Any underwriters may make a market in these securities but will not be

TABLE OF CONTENTS

obligated to do so and may discontinue any market making at any time without notice. We cannot guarantee the liquidity of the trading markets for any securities.

DESCRIPTION OF OUR CAPITAL STOCK

Our amended and restated certificate of incorporation authorizes us to issue 400,000,000 shares of common stock, $0.01 par value per share, and 100,000,000 shares of preferred stock, $0.01 per share. As of December 27, 2019, 242,207,522 shares of our common stock were issued and outstanding and 6,123,782 shares of Tellurian Series C convertible preferred stock (the “Series C Preferred Shares”) were issued and outstanding.

The rights of the holders of our common stock and Series C Preferred Shares are governed by the Delaware General Corporation Law (the “DGCL”), our amended and restated certificate of incorporation, our amended and restated by-laws and the certificate of designations governing the Series C Preferred Shares.

The following is a summary of the material terms of our capital stock, and is qualified in its entirety by reference to the complete text of our amended and restated certificate of incorporation, our amended and restated by-laws and the certificate of designations governing the Series C Preferred Shares, each of which is incorporated by reference in this prospectus. See “Where You Can Find More Information.”

Common Stock

Voting Rights

Holders of common stock are entitled to one vote for each share held on all matters submitted to a vote of stockholders. Cumulative voting in the election of directors is not permitted. Under our amended and restated by-laws, unless otherwise provided in our amended and restated certificate of incorporation or the DGCL with respect to a specified action, matters to be voted on by stockholders are generally decided by a majority of the votes cast, except that contested elections of directors will be decided by a plurality vote. Our amended and restated by-laws provide that the presence at a stockholders’ meeting of one-third of the voting power of our outstanding stock entitled to vote at the meeting will constitute a quorum.

Dividend and Distribution Rights

Holders of outstanding shares of our common stock are entitled to dividends when, as, and if declared by our board of directors out of funds legally available for the payment of dividends (subject to the restrictions on dividends set forth in the certificate of designations governing the Series C Preferred Shares). As a Delaware corporation, we may pay dividends out of surplus or, if there is no surplus, out of net profits for the fiscal year in which a dividend is declared and/or the preceding fiscal year. In the event of our liquidation, dissolution, or winding up of our affairs, holders of our common stock will be entitled to receive ratably our net assets available to the stockholders.

Preemptive, Conversion and Redemption Rights

Holders of our outstanding common stock have no conversion or redemption rights. In addition, holders of our common stock have no preemptive rights under the DGCL. However, Total Delaware, Inc. (“Total”) has a contractual right to purchase its pro rata portion of any new equity securities that Tellurian may issue to a third party on the same terms and conditions as such equity securities are offered and sold to such party, subject to certain exceptions. Total also has certain anti-dilution rights that will entitle it to purchase additional shares of our common stock under certain circumstances if all or a portion of our acquisition of an interest in Driftwood Holdings LP is financed with securities convertible into our common stock. To the extent that additional shares of our common stock may be issued in the future, the relative interests of the then-existing stockholders may be diluted.

Preferred Stock Generally

Our amended and restated certificate of incorporation authorizes our board of directors, subject to any limitations prescribed by law, without further stockholder approval, to establish and to issue from time to time one or more classes or series of preferred stock, covering up to an aggregate of 100,000,000 shares of preferred stock. Each class or series of preferred stock will cover the number of shares and will have the powers, preferences, rights, qualifications, limitations and restrictions determined by our board of directors, which may include, among others, dividend rights, liquidation preferences, voting rights, conversion rights and redemption rights.

Series C Convertible Preferred Stock

Voting Rights

Holders of the Series C Preferred Shares are entitled to one vote for each Series C Preferred Share held on matters submitted to a vote of common stockholders.

Conversion

Holders of the Series C Preferred Shares may convert all or any portion of such shares for shares of Tellurian common stock on a one-for-one basis. At any time after “Substantial Completion” of “Project 1,” each as defined in and pursuant to the Lump Sum Turnkey Agreement for the Engineering, Procurement and Construction of the Driftwood LNG Phase 1 Liquefaction Facility, dated as of November 10, 2017, by and between Driftwood LNG LLC, a Delaware limited liability company and a subsidiary of Tellurian, and Bechtel, or at any time after March 21, 2028, Tellurian has the right, at its option, to cause not less than all of the Series C Preferred Shares to be converted into shares of Tellurian common stock on a one-for-one basis. The conversion ratio will be subject to customary anti-dilution adjustments.

Dividends

The Series C Preferred Shares do not have dividend rights. Tellurian will be prohibited from paying dividends on its common stock so long as the Series C Preferred Shares remain outstanding.

Liquidation

In the event of any liquidation, dissolution or winding up of the affairs of Tellurian (a “Liquidation Event”), after payment or provision for payment of the debts and other liabilities of Tellurian, holders of the Series C Preferred Shares will be entitled to receive the greater of (i) an amount in cash equal to $8.16489 per share and (ii) the amount that would be received by the holders of the Series C Preferred Shares had such holders converted those shares into Tellurian common stock immediately prior to the Liquidation Event.

Priority

So long as any Series C Preferred Shares remain outstanding, Tellurian may not, without the consent of the holders of at least a majority of the Series C Preferred Shares, authorize the issuance of any class of shares that is pari passu with or senior to the Series C Preferred Shares in the payment of dividends or the distribution of assets following a Liquidation Event, except in limited circumstances.

Anti-Takeover Provisions in our Amended and Restated Certificate of Incorporation and Amended and Restated By-Laws

Our amended and restated certificate of incorporation and amended and restated by-laws also contain provisions that we describe in the following paragraphs, which may delay, defer, discourage, or prevent a

TABLE OF CONTENTS

change in control of us, the removal of our existing management or directors, or an offer by a potential acquirer to our stockholders, including an offer by a potential acquirer at a price higher than the market price for the stockholders’ shares.

Among other things, our amended and restated certificate of incorporation and amended and restated by-laws:

•

divide our board of directors into three classes serving staggered three-year terms, which could have the effect of increasing the length of time necessary to change the composition of a majority of the board of directors;

•

provide that all vacancies on the board of directors, including newly created directorships, will, except as otherwise required by law, be filled by the vote of a majority of directors then in office;

•

provide our board of directors with the ability to authorize currently undesignated preferred stock. This ability makes it possible for our board of directors to issue, without stockholder approval, preferred stock with voting or other rights or preferences designated by the board that could have the effect of impeding the success of any attempt to change control of us;

•

establish advance notice procedures with regard to stockholder proposals relating to the nomination of candidates for election as directors or new business to be brought before meetings of our stockholders. These procedures provide that notice of stockholder proposals must be timely given in writing to our corporate secretary prior to the meeting at which the action is to be taken. Generally, to be timely, notice must be received at our principal executive offices not less than 90 days, and not more than 120 days, prior to the first anniversary of the prior year’s annual meeting (or, in the case of a special meeting, not less than 90 days or more than 120 days prior to the date of the meeting). Our amended and restated by-laws specify the information that must be included in a stockholder’s notice. These requirements may prevent stockholders from bringing matters before the stockholders at an annual or special meeting;

•

provide that stockholders may not act by written consent in lieu of a meeting unless the action, and the taking of such action by written consent, has been approved in advance by the board of directors;

•

provide that stockholders are not permitted to call special meetings of stockholders. Only our chairman of the board, president, and the board of directors are permitted to call a special meeting of stockholders; and

•

provide that our board of directors may alter, amend, or repeal our by-laws or approve new by-laws without further stockholder approval, and provide that a stockholder amendment to the by-laws requires a favorable vote of two-thirds of the voting power of all outstanding voting stock.

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:

•

our board of directors approved either the business combination or the transaction that resulted in the stockholder becoming an interested stockholder prior to the date the person attained that status;

•

upon consummation of the transaction that resulted in the stockholder becoming an interested stockholder, the interested stockholder owned at least 85% of our voting stock outstanding at the time the transaction commenced, excluding, for purposes of determining the number of shares outstanding, shares owned by persons who are directors and also officers and employee stock plans

TABLE OF CONTENTS

in which employee participants do not have the right to determine confidentially whether shares held under the plan will be tendered in a tender or exchange offer; or

•

the business combination is approved by our board of directors on or subsequent to the date the person became an interested stockholder and authorized at an annual or special meeting of the stockholders by the affirmative vote of the holders of at least two-thirds of the outstanding voting stock that is not owned by the interested stockholder.

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 and that are favored by the holders of a majority of our then-outstanding stock.

DESCRIPTION OF OUR WARRANTS

The following is a summary of the general terms of any warrants that we may offer under this prospectus and related warrant agreements and certificates. You should refer to the warrant agreement, including the form of warrant certificate representing the warrants, relating to the specific warrants being offered for complete terms, which will be described in an accompanying prospectus supplement. Such warrant agreement, together with the warrant certificate, will be filed with the SEC in connection with the offering of the specific warrants.

We may issue warrants for the purchase of common stock, preferred stock or any combination thereof. Warrants may be issued independently or together with any other offered securities, and may be attached to or separate from any offered securities.

We will evidence each series of warrants by warrant certificates that we will issue under a separate warrant agreement. We may enter into an agreement with a warrant agent and, if so, we will indicate the name and address of the warrant agent in the applicable prospectus supplement relating to the particular series of warrants.

The particular terms of any issue of warrants will be described in the prospectus supplement relating to the series. Those terms may include:

•

the title of such warrants;

•

the aggregate number of such warrants;

•

the price or prices at which such warrants will be issued;

•

the currency or currencies (including composite currencies) in which the price of such warrants may be payable;

•

the terms of the securities issuable upon exercise of such warrants and the procedures and conditions relating to the exercise of such warrants;

•

the price at which the securities issuable upon exercise of such warrants may be acquired;

•

the dates on which the right to exercise such warrants will commence and expire;

•

any provisions for adjustment of the number or amount of securities receivable upon exercise of the warrants or the exercise price of the warrants;

•

if applicable, the minimum or maximum amount of such warrants that may be exercised at any one time;

•

if applicable, the designation and terms of the securities with which such warrants are issued and the number of such warrants issued with each such security or principal amount of such security;

•

if applicable, the date on and after which such warrants and the related securities will be separately transferable;

•

information with respect to book-entry procedures, if any; and

TABLE OF CONTENTS

•

any other terms of such warrants, including terms, procedures, and limitations relating to the exchange or exercise of such warrants.

Exercise of Warrants

Each warrant will entitle its holder to purchase the number of shares of common stock, preferred stock or combination thereof at the exercise price set forth in, or calculable as set forth in, the applicable prospectus supplement. Unless we otherwise describe in the applicable prospectus supplement, holders of the warrants may exercise the warrants at any time up to the expiration date set forth in the applicable prospectus supplement. After the close of business on the expiration date, unexercised warrants will become void. We will describe in the applicable prospectus supplement the place or places where, and the manner in which, warrants may be exercised. We will set forth on the reverse side of the applicable warrant certificate and in the applicable prospectus supplement the information that the holder of the warrant will be required to deliver upon exercise.

Upon receipt of payment and the warrant certificate properly completed and duly executed, we will, as soon as practicable, forward the purchased securities. If less than all of the warrants represented by the warrant certificate are exercised, a new warrant certificate will be issued for the remaining unexercised warrants.

Enforceability of Rights by Holders of Warrants

Each warrant agent will act solely as our agent under the applicable warrant agreement and will not assume any obligation or relationship of agency or trust with any holder of any warrant. A single bank or trust company may act as warrant agent for more than one issue of warrants.

DESCRIPTION OF OUR UNITS

We may issue units comprised of one or more securities described in this prospectus in any combination. Each unit will be issued so that the holder of the unit is also the holder of each security included in the unit. Thus, the holder of a unit will have the rights and obligations of a holder of each included security. The units may be issued under unit agreements to be entered into between us and a bank or trust company, as unit agent, as described in the prospectus supplement relating to units being offered. The prospectus supplement will describe:

•

the designation and terms of the units and of the securities comprising the units, including whether and under what circumstances the securities comprising the units may be held or transferred separately;

•

a description of the terms of any unit agreement governing the units;

•

a description of the provisions for the payment, settlement, transfer, or exchange of the units;

•

a discussion of material federal income tax considerations, if applicable; and

•

whether the units will be issued in fully registered or global form.

The descriptions of the units in this prospectus and in any prospectus supplement are summaries of the material provisions of the applicable unit agreements. These descriptions do not contain all of the provisions of those unit agreements in their entirety and may not contain all the information that you may find useful. We urge you to read the applicable unit agreements because they, and not the summaries, define your rights as holders of the units. For more information, please review the form of the relevant unit
