the Acquired Shares or the legal authority or ability of Tamboran to perform in any material respects its obligations hereunder (a “Tamboran Material Adverse Effect”).

(f)Tamboran is not in default or violation (and no event has occurred which, with notice or the lapse of time or both, would constitute a default or violation) of any term, condition or provision of (i) the organizational documents of Tamboran, (ii) any loan or credit agreement, note, bond, mortgage, indenture, lease or other agreement, permit, franchise or license to which, as of the date of this Subscription Agreement, Tamboran is a party or by which Tamboran’s properties or assets are bound or (iii) any law, statute or any judgment, order, rule or regulation of any court or governmental agency or body, domestic or foreign, having jurisdiction over Tamboran or any of its properties, except, in the case of clauses (ii) and (iii), for defaults or violations that have not had and would not be reasonably likely to have, individually or in the aggregate, a Tamboran Material Adverse Effect.

(i)As of their respective filing dates, all reports required to be filed by Tamboran with the SEC since June 26, 2024 (the “SEC Reports”) complied in all material respects with the applicable requirements of the Securities Exchange Act of 1934, as amended (the “Exchange Act”), and the rules and regulations of the SEC promulgated thereunder. None of the SEC Reports, when filed or, if amended, as of the date of such amendment with respect to those disclosures that are amended, contained any untrue statement of a material fact or omitted to state a material fact necessary to make the statements therein, in the light of the circumstances under which they were made, not misleading. The financial statements of Tamboran included in the SEC Reports comply in all material respects with applicable accounting requirements and the rules and regulations of the SEC with respect thereto as in effect at the time of filing and fairly present in all material respects the financial position of Tamboran as of and for the dates thereof and the results of operations and cash flows for the periods then ended, subject, in the case of unaudited financial statements, to normal, year-end audit adjustments. A copy of each SEC Report is available to the Subscriber via the SEC’s EDGAR system. There are no material outstanding or unresolved comments in comment letters received by Tamboran (or any affiliate or subsidiary thereof) from the staff of the Division of Corporation Finance of the SEC with respect to any of the SEC Reports.

(j)Other than as disclosed in the SEC Reports, Tamboran has established and maintains systems of internal accounting controls that are designed to provide, in all material respects, reasonable assurance that (i) all transactions are executed in accordance with management’s authorization and (ii) all transactions are recorded as necessary to permit preparation of proper and accurate financial statements in accordance with GAAP and to maintain accountability for Tamboran’s assets. Tamboran maintains, and has maintained, books and records in the ordinary course of business that are accurate and complete and properly reflect the revenues, expenses, assets and liabilities of Tamboran in all material respects.

(k)Since the date of the balance sheet included in Tamboran’s Form 10-K for the year ended June 30, 2024, there has been (i) no Tamboran Material Adverse Effect, (ii) no transaction which is material to Tamboran and its subsidiaries taken as a whole, (iii) no obligation or liability, direct or contingent (including any off-balance sheet obligations), incurred by Tamboran or its subsidiaries, which is material to Tamboran and its subsidiaries taken as a whole, (iv) no change in the capital stock or outstanding indebtedness of Tamboran and its subsidiaries, other than as described in the SEC Reports and Section 3(h) of this Subscription Agreement and (v) no dividend or distribution of any kind declared, paid or made on the capital stock of Tamboran or any of its subsidiaries.

(l)Tamboran and each of its subsidiaries maintain insurance covering their respective properties, operations, personnel and businesses as Tamboran reasonably deems adequate; such insurance insures against such losses and risks in accordance with customary industry practice to protect Tamboran and its subsidiaries and their respective businesses and which is commercially reasonably for the current conduct of their respective businesses; to Tamboran’s Knowledge, all such insurance is fully in force on the date hereof and is expected to be fully in force at each time of purchase, if any; neither Tamboran nor any subsidiary has reason to believe that it will not be able to (i) renew any such insurance as and when such insurance expires or (ii) obtain comparable coverage from similar institutions as may be necessary or appropriate to conduct its business as now conducted at a cost that would not, individually or in the aggregate, reasonably be expected to result in any Tamboran Material Adverse Effect. “Tamboran’s Knowledge” with respect to any statement means the actual knowledge, or knowledge that would have been acquired after reasonable inquiry, of the executive officers or directors of Tamboran.

(m)Assuming the accuracy of Subscriber’s representations and warranties set forth in Section 4, no registration under the Securities Act of 1933, as amended (the “Securities Act”) is required for the offer and sale of the Acquired Shares by Tamboran to Subscriber.

(n)Neither Tamboran nor any person acting on its behalf has engaged or will engage in any form of general solicitation or general advertising within the meaning of applicable securities laws in connection with any offer or sale of the Acquired Shares.

(o)None of Tamboran, any of its subsidiaries nor any person acting on their behalf has taken or will take, directly or indirectly, any action designed to or that is likely to cause or result in stabilization or manipulation of the price of any security of Tamboran to facilitate the sale or resale of the Acquired Shares or otherwise, and has taken no action which could reasonably be expected to directly or indirectly violate Regulation M under the Exchange Act.

(p)Except for such matters as have not had and would not be reasonably likely to have, individually or in the aggregate, a Tamboran Material Adverse Effect, there is no proceeding pending, or, to Tamboran’s Knowledge, threatened against Tamboran or any judgment, decree, injunction, ruling or order of any governmental entity or arbitrator outstanding against Tamboran.

(q)Except for placement fees payable to the Placement Agent (as defined within), Tamboran has not paid, and is not obligated to pay, any brokerage, finder’s or other fee or commission in connection with its issuance and sale of the Acquired Shares, including, for the avoidance of doubt, any fee or commission payable to any equityholder or affiliate of Tamboran.

(r)None of Tamboran, its subsidiaries, any person acting on its behalf nor, to Tamboran’s Knowledge, any of its affiliates has, directly or indirectly, at any time within the applicable period set forth in Rule 152 promulgated under the Securities Act, made any offers or sales of any security or solicited any offers to buy any security under circumstances that would (i) eliminate the availability of the exemption from registration under the Securities Act in connection with the sale by Tamboran of the Acquired Shares as contemplated hereby or (ii) cause the sale of the Acquired Shares pursuant to this Subscription Agreement to be integrated with prior offerings by Tamboran for purposes of any applicable law, regulation or stockholder approval provisions, including, without limitation, under the rules and regulations of any exchange on which any of the securities of Tamboran are listed or designated.

(s)Other than the Subscribers and the parties to the Sheffield RRA (as defined below), no person has any right to cause Tamboran to effect the registration under the Securities Act of the offer and sale of any securities of Tamboran other than (i) those offers and sales which are currently registered on an effective registration statement on file with the SEC and (ii) such rights as have been temporarily waived.

(t)The Common Stock is registered pursuant to Section 12(b) or Section 12(g) of the Exchange Act, and Tamboran has taken no action designed to terminate the registration of the Common Stock under the Exchange Act, nor has Tamboran received any notification that the SEC or the NYSE is contemplating terminating such registration or listing. Tamboran is, and immediately following the Closing will be, in compliance with all applicable listing requirements of the NYSE.

(u)Neither Tamboran nor any of its subsidiaries has taken any steps to seek protection pursuant to any law or statute relating to bankruptcy, insolvency, reorganization, receivership, liquidation or winding up, nor does Tamboran or any subsidiary have any knowledge or reason to believe that any of their respective creditors intend to initiate involuntary bankruptcy proceedings or any actual knowledge of any fact which would reasonably lead a creditor to do so. Tamboran and its subsidiaries, individually and on a consolidated basis, are not as of the date hereof, and after giving effect to the transactions contemplated hereby to occur at the Closing, will not be Insolvent (as defined below). For purposes hereof, “Insolvent” means, with respect to any person, (i) the present fair saleable value of such person’s assets is less than the amount required to pay such person’s total indebtedness, (ii) such person is unable to pay its debts and liabilities, subordinated, contingent or otherwise, as such debts and liabilities become absolute and matured, (iii) such person intends to incur or believes that it will incur debts that would be beyond its ability to pay as such debts mature or (iv) such person has unreasonably small capital with which to conduct the business in which it is engaged as such business is now conducted and is proposed to be conducted.

(v)Neither Tamboran nor any subsidiary nor, to Tamboran’s Knowledge, any director, officer, agent, employee or affiliate of Tamboran or any subsidiary is currently the target of or otherwise subject to any restrictions under, any sanctions administered or enforced by the United States, including without limitation, the Office of Foreign Assets Control of the U.S. Treasury Department (“OFAC”) or the U.S. Department of State; the United Nations Security Council; Canada; the European Union; the United Kingdom; or other government authority with jurisdiction over the parties (collectively, “Sanctions”). None of Tamboran or any of its subsidiaries, affiliates, or agents is located, organized or resident in a country or territory that is the subject or target of country or territory-wide Sanctions, including, without limitation, Crimea,

Cuba, Iran, North Korea or Syria (each, a “Sanctioned Country”). Tamboran and its subsidiaries, affiliates, or agents will not directly or indirectly use the proceeds from the Acquired Shares, or lend, or knowingly contribute or otherwise make available such proceeds: (i) to fund or facilitate any activities of or business with any person that is the target of, or otherwise subject to restrictions under, any Sanctions; (ii) to fund or facilitate any activities of or business in any Sanctioned Country; or (iii) in any other manner that will result in a violation by any person (including any person participating in the transaction, whether as underwriter, initial purchaser, advisor, investor or otherwise) of Sanctions. In the past five years, none of Tamboran nor any of its subsidiaries, affiliates, or agents have engaged in or are now engaged in any dealings or transactions: (i) with, or involving the interests or property of, any person that, at the time of the dealing or transaction, was or is subject to restrictions imposed by any Sanctions or located, organized or resident in a Sanctioned Country; or (ii) that are otherwise prohibited by Sanctions.

(w)The operations of Tamboran and its subsidiaries are in compliance with applicable financial record-keeping and reporting requirements of the Currency and Foreign Transactions Reporting Act of 1970, as amended, applicable money laundering and anti-terrorism financing statutes and applicable rules and regulations thereunder (collectively, the “Money Laundering Laws”), and no action or proceeding by or before any court or governmental agency, authority or body or any arbitrator involving Tamboran or any subsidiary with respect to the Money Laundering Laws is pending or, to Tamboran’s Knowledge or the knowledge of any subsidiary, threatened or being investigated.

(x)Tamboran has not received any written communication from a governmental entity that alleges that Tamboran is not in compliance with or is in default or violation of any applicable law, except where such non-compliance, default or violation would not, individually or in the aggregate, be reasonably likely to have a Material Adverse Effect.

(c)If a Piggyback Registration or Piggyback Shelf Takedown is initiated as an underwritten offering on behalf of a holder of Common Stock other than Acquired Shares, and the managing underwriter advises Tamboran in writing that in its reasonable and good faith opinion the number of shares of Common Stock proposed to be included in such registration or takedown, including all Acquired Shares and all other shares of Common Stock proposed to be included in such underwritten offering, exceeds the number of shares of Common Stock which can be sold in such offering and/or that the number of shares of Common Stock proposed to be included in any such registration or takedown would adversely affect the price per share of the Common Stock to be sold in such offering, Tamboran shall include in such registration or takedown (i) first, the shares of Common Stock requested to be included therein by the holder(s) requesting such registration or takedown and by the holders of Acquired Shares, allocated pro rata among all such holders on the basis of the number of shares of Common Stock other than the Acquired Shares (on a fully diluted, as converted basis) and the number of Acquired Shares, as applicable, owned by all such holders or in such manner as they may otherwise agree; and (ii) second, the shares of Common Stock requested to be included therein by other holders of Common Stock, allocated among such holders in such manner as they may agree.

(d)Tamboran shall select the investment banking firm or firms to act as the managing underwriter or underwriters in connection with any Piggyback Registration or Piggyback Shelf Takedown.
