Arrangement Agreement

On September 30, 2025, Tamboran Resources Corporation, a Delaware corporation (“Tamboran”), Tamboran (Beetaloo) Pty

Ltd, a company organized under the laws of Australia and an indirect wholly owned subsidiary of Tamboran (“Australia Sub”),

Tamboran Resources Investments Holding Corporation, a Delaware corporation and an indirect wholly owned subsidiary of Tamboran

(“U.S. Sub”), and Falcon Oil & Gas Ltd., a corporation incorporated under the Business Corporations Act (British Columbia)

(“Falcon”), entered into an Arrangement Agreement (the “Arrangement Agreement”), pursuant to which, on the terms and subject to

the conditions set forth therein, Tamboran agreed to indirectly acquire all of the equity interests of Falcon’s subsidiaries (the

transactions contemplated by the Arrangement Agreement, the “Transactions”). The Transactions will be effected by way of a plan of

arrangement under the Business Corporations Act (British Columbia) (the “Plan of Arrangement”).

Structure and Consideration

Pursuant to the terms of the Arrangement Agreement and the Plan of Arrangement, (a) Australia Sub will acquire from

Falcon approximately 98.1% of the issued and outstanding equity interests (the “Falcon Interests”) of Falcon Oil & Gas Australia

Limited, a company organized under the laws of Australia (“Falcon Australia”), which represents all of Falcon’s interests in Falcon

Australia, and (b) U.S. Sub will acquire from Falcon all of the issued and outstanding equity interests (together with the Falcon

Interests, the “Subject Interests”) of (i) TXM Oil and Gas Exploration Kft., a company incorporated under the laws of Hungary, (ii)

Falcon Oil & Gas Ireland Limited, a company incorporated under the laws of Ireland, (iii) Falcon Oil & Gas Holdings Ireland Limited,

a company incorporated under the laws of Ireland, and (iv) Falcon Exploration and Production South Africa (Pty) Ltd, a company

incorporated under the laws of South Africa. In exchange for the Subject Interests, Tamboran will (a) issue to Falcon 6,537,503 shares

(the “Stock Consideration”) of its common stock, par value $0.001 per share (the “Tamboran Common Stock”), and (b) pay

$23,663,080 in cash.

In addition, existing options to purchase Falcon common shares will be cancelled. Upon closing of the Transactions

(“Closing”), Tamboran will enter into consulting agreements with certain directors and officers of Falcon, pursuant to which

Tamboran will issue to those directors and officers an aggregate of up to 369,084 Tamboran options with an exercise price of

US$21.94 per share.

Governance

Upon closing of the Transactions, Tamboran will continue to be led by Chairman and Interim Chief Executive Officer Dick

Stoneburner, and no changes to the Board of Directors or the management team of Tamboran are planned.

Conditions to the Transactions

The Closing is subject to certain conditions, including, among others, (a) the approval of the Transactions by at least 66 ⅔%

of the votes cast by Falcon shareholders and, if required by applicable Canadian securities laws, a simple majority of the votes cast by

Falcon shareholders, excluding Falcon common shares held by persons required to be excluded under such laws (the “Falcon

Requisite Shareholder Approval”), at a meeting of Falcon shareholders, (b) the approval of the issuance of the Stock Consideration

(the “Stock Issuance”) by a majority of the votes cast by Tamboran stockholders (the “Tamboran Stockholder Approval”) at a meeting

of Tamboran stockholders, (c) the approval of the Transactions by the Supreme Court of British Columbia on terms consistent with the

Arrangement Agreement and otherwise reasonably satisfactory to the parties, (d) the authorization for listing of the Stock

Consideration on the New York Stock Exchange and (e) the absence of any law or order enjoining, restricting or prohibiting the

consummation of the transactions contemplated by the Transactions.

The obligation of each party to consummate the Transactions is also conditioned upon (a) the other party’s representations

and warranties being true and correct (subject to certain materiality thresholds), (b) the other party having performed in all material

respects its obligations under the Arrangement Agreement, (c) the absence of any material adverse effect in respect of the other party,

and (d) the receipt of an officer’s certificate from the other party certifying the satisfaction of each such condition.

In addition, the obligation of Tamboran to consummate the Transactions is subject to (a) no more than 5% of the issued and

outstanding Falcon common shares exercising dissent rights in connection with the Falcon Requisite Shareholder Approval, (b) all

requisite regulatory clearances or approvals have been obtained and remain in full force and effect, (c) the execution and delivery of

certain support agreements and stock option cancellation agreements by certain Falcon shareholders, and (d) the approval of the

Transactions by Falcon Australia’s minority shareholders by December 30, 2025 (the “Minority Shareholder Approval”).

Termination Rights

The Arrangement Agreement contains certain termination rights for both Tamboran and Falcon, including, among others, (a)

upon the mutual consent of Tamboran and Falcon, (b) by either Tamboran or Falcon if (i) the Transactions are not consummated on or

prior to March 30, 2026 (which date, if certain requisite regulatory approvals have not been obtained and all other conditions to the

Closing have been satisfied or waived on such date, will be automatically extended to June 30, 2026), or (ii) a final non-appealable

governmental order has been enacted, entered, promulgated, adopted, issued or enforced prohibiting or making illegal any of the

transactions contemplated by the Transactions, (c) by either Tamboran or Falcon if either the Falcon Requisite Shareholder Approval

or Tamboran Stockholder Approval shall not have been obtained, (d) by either Tamboran or Falcon if the other party breaches any of

its representations, warranties or covenants in the Arrangement Agreement in a manner that would cause the corresponding condition

to not be satisfied, subject to certain conditions, (e) by either Tamboran or Falcon if the other party’s board of directors changes its

recommendation with respect to the Stock Issuance or Transactions, as applicable, (f) by either Tamboran or Falcon if there is a willful

and material breach by the other party of the applicable restrictions with respect to soliciting competing business combination

transactions, (g) by Tamboran if Falcon’s undisclosed liabilities exceed $3 million and (h) automatically if the Minority Shareholder

Approval is not obtained.

If the Arrangement Agreement is terminated in certain specified circumstances, Tamboran or Falcon would be required to

pay the other party a termination fee of $3.75 million or $1.62 million, respectively.

for a transaction of this nature, in each case generally subject to customary materiality qualifiers. Among other things, each party has

without the prior written consent of the other party, (b) not to solicit alternative business combination transactions and (c) to convene

meetings of its respective shareholders for the purpose of obtaining the Tamboran Stockholder Approval or Falcon Requisite

Shareholder Approval, as applicable, and to recommend to its respective shareholders to approve the Stock Issuance or the

Forward-Looking Statements

Certain statements in this report concerning the transaction, including any statements regarding the expected timetable for completing

the transaction, the results, effects, benefits and synergies of the transaction, future opportunities for the combined company, future

financial performance and condition, guidance and any other statements regarding Tamboran’s or Falcon’s future expectations, beliefs,

plans, objectives, financial conditions, assumptions or future events or performance that are not historical facts are “forward-looking”

statements based on management’s current expectations, assumptions and estimates on the date hereof, and there can be no assurance

that actual strategies, actions or results will not differ materially from expectations. Forward-looking statements are all statements

other than statements of historical facts. The words “anticipate,” “believe,” “ensure,” “expect,” “if,” “intend,” “estimate,” “probable,”

“project,” “forecasts,” “predict,” “outlook,” “aim,” “will,” “could,” “should,” “would,” “potential,” “may,” “might,” “anticipate,”

“likely” “plan,” “positioned,” “strategy,” and similar expressions or other words of similar meaning, and the negatives thereof, are

intended to identify forward-looking statements. Specific forward-looking statements include statements regarding Tamboran’s or

Falcon’s plans and expectations with respect to the transaction, timing of closing, and the anticipated impact of the transaction on the

combined company’s results of operations, financial position, growth opportunities and competitive position. The forward- looking

statements are intended to be subject to the safe harbor provided by Section 27A of the Securities Act of 1933, as amended, Section

21E of the Securities Exchange Act of 1934, as amended, and the Private Securities Litigation Reform Act of 1995.

These forward-looking statements involve significant risks and uncertainties that could cause actual results to differ materially from

those anticipated, including, but not limited to, the possibility that stockholders of Tamboran may not approve the issuance of new

shares of Tamboran common stock in the transaction or that shareholders of Falcon may not approve the transaction; the risk that a

condition to closing of the transaction may not be satisfied; that either party may terminate the arrangement agreement or that the

closing of the transaction might be delayed or not occur at all; the outcome of any legal proceedings that may be instituted against

Tamboran or Falcon; reputational risks and potential adverse reactions from or changes to the relationships with the companies’

employees or other business partners of Tamboran or Falcon, including those resulting from the announcement or completion of the

transaction; the diversion of management’s time on transaction-related issues; the dilution caused by Tamboran’s issuance of common

stock in connection with the transaction; the ultimate timing, outcome and results of integrating the operations of Tamboran and

Falcon; the effects of the business combination of Tamboran and Falcon, including the combined company’s future financial

condition, results of operations, strategy and plans; changes in capital markets and the ability of the combined company to finance

operations in the manner expected; regulatory approvals of the transaction; the effects of commodity prices; the risks of oil and gas

activities; and the fact that operating costs and business disruption may be greater than expected following the public announcement or

consummation of the transaction. Expectations regarding business outlook, including changes in strategies for the combined

company’s operations, oil and natural gas market conditions, legal, economic and regulatory conditions, and environmental matters,

are only forecasts regarding these matters.

These factors are not necessarily all of the factors that could cause Tamboran’s or Falcon’s actual results, performance, or

achievements to differ materially from those expressed in or implied by any of the forward-looking statements. Other unknown or

unpredictable factors also could harm Tamboran’s or Falcon’s results. Additional factors that could cause results to differ materially

from those described above can be found in Tamboran’s Annual Report on Form 10-K for the fiscal year ended June 30, 2025, and

subsequent Quarterly Reports on Form 10-Q, which are on file with the Securities and Exchange Commission (the “SEC”) and

available from Tamboran’s website at www.tamboran.com under the “Investor Relations” tab, and in other documents Tamboran files

with the SEC; and in Falcon’s annual information form for the year ended December 31, 2024, which is  on SEDAR+ and available

from Falcon’s website at www.falconoilandgas.com under the “Investor Centre” tab, and in other documents Falcon files on

SEDAR+.

All forward-looking statements speak only as of the date they are made and are based on information available at that time. Neither

Tamboran nor Falcon assumes any obligation to update forward-looking statements to reflect circumstances or events that occur after

the date the forward-looking statements were made or to reflect the occurrence of unanticipated events except as required by

applicable securities laws. As forward-looking statements involve significant risks and uncertainties, caution should be exercised

against placing undue reliance on such statements.
