Timing of issue of Retention Licence (g) Each party must do all things within its reasonable control (and must procure that its Affiliates must do all things within their reasonable control) to ensure that the North FSDA RL, South FSDA RL, P2DA RL and Dev B RL are not granted prior to the P2DA Completion Date. 4.3 EP 117 Portion and EP 98 Portion (a) The parties acknowledge and agree that: (i) the formation of the P2DA includes an area covered by EP 117 which is approximately 30,000ac (EP117 Portion); (ii) the formation of the BCD Area includes an area covered by EP 98 which is approximately 10,000ac (EP 98 Portion); and (iii) as at the Execution Date: (A) a Retention Licence which includes acreage from more than one Exploration Permit area cannot be granted under the Petroleum Act; and (B) therefore, the application for: (1) the P2DA RL contemplated under clause 4.2 will not include the EP117 Portion; and (2) the Dev B RL contemplated under clause 4.2 will not include the EP98 Portion. (b) As soon as reasonably practicable following any change in legislation that would permit the EP117 Portion and EP98 Portion to be merged into the P2DA RL and Dev B RL (respectively) or, if such legislation has not been enacted by 30 September 2026, then promptly following that date, the parties agree to cooperate and do all

15 things necessary to ensure that the EP117 Portion forms part of the P2DA RL and the EP98 Portion forms part of Dev B RL. (c) The parties agree that DWE does not have a right to elect to assume the role of Manager under the JVSA pursuant to clause 13.3(g)(i) or (ii) of the JVSA solely on the basis that: (i) the EP 117 Portion is not included in the application for the P2DA RL and the EP 98 Portion is not included in the application for the Dev B RL; or (ii) the EP 117 Portion is not included in the P2DA RL and the EP 98 Portion is not included in the Dev B RL, at the time the interests in those Retention Licences are transferred to the relevant parties, for the reason described in clause 4.3(a)(iii)(A). (d) Unless and until the EP 117 Portion forms part of the P2DA RL under this clause 4.3, Tamboran, DWE and the Manager must take all steps reasonably required to ensure that no wells are drilled or drill pads developed or installed within the EP 117 Portion under the JOA or any New Area JOA. (e) Unless and until the EP 98 Portion forms part of the Dev B RL under this clause 4.3, Tamboran, DWE and the Manager must take all steps reasonably required to ensure that no wells are drilled or drill pads developed or installed within the EP 98 Portion under the JOA or any New Area JOA. 5. Pilot Infrastructure The parties agree and acknowledge that: (a) following the Acreage Realignment Date, DWE (and its Affiliates) and Tamboran (and its Affiliates) will each hold: (i) a 50% direct or indirect interest in the capacity in the SPP and the SPCF (including that DWE (and its Affiliates) and Tamboran (and its Affiliates) will each hold 50% of Falcon’s interest in the SPP and the SPCF); and (ii) a corresponding share of all associated obligations, liabilities and commitments; and (b) DWE and Tamboran must each take all steps reasonably required to give effect to this, subject to the terms and conditions set out in the JVSA, including the ‘Expansion Principles’ set out in clause 13.16 of the JVSA (which will take precedence to the extent of any conflict or inconsistency between this clause and the JVSA). 6. Amendments to existing royalties (a) With effect on and from the P2DA Completion Date (where the Acreage Realignment Date has not occurred), each of Tamboran, TBN and DWE, on behalf of itself and any of its Affiliates: (i) assumes and shall be liable to pay, perform and discharge its share of any royalties; and (ii) indemnifies the other party and its Affiliates against any Liabilities or other claims arising out of or in connection with any failure to pay its share of any royalty,

16 in respect of the different areas of the Permits, as set out in Table 1 of Schedule 3. (b) With effect on and from the date that both the Acreage Realignment Date and P2DA Completion Date have occurred, Tamboran, TBN and DWE, on behalf of itself and any of its Affiliates: (i) assumes and shall be liable to pay, perform and discharge its share of any royalties; and (ii) indemnifies the other party and its Affiliates against any Liabilities or other claims arising out of or in connection with any failure to pay its share of any royalty, in respect of the different areas of the Permits, as set out in Table 2 of Schedule 3. (c) Tamboran, TBN and DWE each agree to procure that it and its relevant Affiliates enter into any documentation reasonably required to give effect to the assumption of the royalty obligations set out in clauses 6(a) and 6(b). (d) For the purpose of clause 6(c), the parties acknowledge that the P2DA Completion Date and the Acreage Realignment Date may occur on the same date or different dates or in close succession. The parties agree to cooperate and act reasonably to ensure that the relevant assumption deeds in respect of the royalties are entered into in a timely and practical manner (including agreeing any required amendments), where required and agreed with the relevant counterparty. 7. Drag-along rights in P2DA (a) Subject to clause 7(d), with effect on and from the P2DA Completion Date, DWE and Tamboran agree and acknowledge that TBN (and/or any other relevant Tamboran Party) (Tamboran Farmee) has a drag-along right in respect of the relevant Daly Waters Parties’ P2DA Interest if (in respect of both transactions contemplated by clause 7(d)): (i) the Acreage Realignment Date has occurred; and (ii) [Redacted]. (b) The drag-along right will operate so that if: (i) Tamboran Farmee has received prior to the P2DA Completion Date, or receives on or after the P2DA Completion Date, a bona fide offer from a third party to acquire or farm-in to P2DA that it accepts; (ii) the pre-conditions in clause 7(a)(i) or 7(a)(ii) have both been met; and (iii) the applicable farm-out or sale terms that apply to the Daly Waters Parties and Tamboran Farmee are equivalent in all material respects under the proposed sale or farm-out, Tamboran Farmee has the right to issue a notice setting out the proposed third party that has made the offer and the commercial terms (including the pricing) (Drag Along Notice) and attaching a copy of the relevant transaction document to the Daly Waters Parties requiring the Daly Waters Parties to sell to the third party specified in that notice part of Daly Waters Parties’ P2DA Interest specified in the notice (Drag Along Interest) provided that:

17 (iv) the aggregate of the Daly Waters Parties’ P2DA Interest after the relevant farm-out does not decrease below 11%; (v) the Daly Waters Parties (in aggregate) and Tamboran Farmee will each sell or farm-out the same proportion of their P2DA Interest (based on the P2DA Interests set out in Table 2 of Schedule 2 unless the parties agree at that time that those P2DA Interests do not accurately reflect the interests that would be held in the PSDA at the relevant time), provided that this clause 7(b)(v) will not apply to limit the sale or farm-out of Tamboran Farmee’s P2DA Interest to the extent that the sale or farm-out on a proportionate basis would cause the Daly Waters Parties’ P2DA Interest in aggregate to be less than 11%; (vi) the Daly Waters Parties sale or farm-out to the third party must be on the same terms and conditions as Tamboran Farmee’s sale or farm-out (as set out in the Drag Along Notice) in all material respects; and (vii) DWE may, at its sole election by notice in writing to Tamboran Farmee within 10 Business Days following receipt of a Drag Along Notice, elect which Daly Waters Parties (which may be one or more), and the proportion that each Daly Waters Party, will sell or farm-out its P2DA Interest. (c) If Tamboran Farmee issues a Drag Along Notice in accordance with clause 7(b): (i) the relevant Daly Waters Parties (as nominated under clause 7(b)(vii) or, in the absence of such nomination within the 10 Business Day period described in clause 7(b)(vii), each of the relevant Daly Waters Parties on a pro rata basis) must sell its or their proportion of the Drag Along Interest to the third party on the terms stated in the Drag Along Notice; and (ii) the parties must do all things and execute all documents (including, in the case of DWE, procuring that each applicable Daly Waters Party does all things and executes all documents) as are reasonably necessary to effect the sale. (d) The Tamboran Farmee may only issue a maximum of two Drag Along Notices under this clause 7 in relation to the first two transactions that the Tamboran Farmee enters into in respect of the P2DA or its P2DA Interest, based on the following: (i) if the first Proposed Farm-out the Tamboran Farmee enters into in respect of the P2DA or its P2DA Interest is a transaction under which the third party has the right to acquire, in aggregate, a P2DA Interest of greater than 10%, the Tamboran Farmee may issue a Drag Along Notice in relation to that transaction but will not be entitled to issue a Drag Along Notice in relation to any further transactions (regardless of whether or not it issued a Drag Along Notice in respect of the first transaction); (ii) if the first Proposed Farm-out the Tamboran Farmee enters into in respect of the P2DA or its P2DA Interest is a transaction under which the third party has the right to acquire, in aggregate, a P2DA Interest of 10% or less, the Tamboran Farmee may issue a Drag Along Notice in relation to that transaction and (provided that the third party has not actually acquired a P2DA Interest of greater than 10%) will be entitled to issue a Drag Along Notice in relation to the next transaction the Tamboran Farmee enters into in respect of the P2DA or its P2DA Interest (regardless of whether or not it issued a Drag Along Notice in respect of the first transaction). For the avoidance of doubt:

18 (A) clauses 7(b)(iv) to 7(b)(vii) shall continue to apply in respect of that second transaction; and (B) any amendment or variation to the first transaction that results in the third party having the right to acquire, in aggregate, a P2DA Interest of greater than 10% shall be deemed to be a new transaction for the purposes of this clause 7(d)(ii); (iii) if the Tamboran Farmee has not issued a Drag Along Notice in relation to either of the first two transactions that the Tamboran Farmee enters into relating to the P2DA or its P2DA Interest, the Tamboran Farmee’s right to issue a Drag Along Notice under this clause 7 shall expire. 8. Tag along rights 8.1 Tag along rights in P2DA (a) With effect on and from the P2DA Completion Date, Tamboran agrees and acknowledges that the Daly Waters Party holding an interest in the P2DA and Elliott have a tag-along right in respect of the Daly Waters Parties’ P2DA Interest. (b) The Tamboran Parties may not complete the Transfer of any of their P2DA Interest unless they have complied with, and given effect to, the tag-along right set out in this clause 8. (c) If Tamboran Farmee wishes to Transfer any P2DA Interest (a Tag Sale Interest) to another party then Tamboran Farmee must notify DWE in writing (Tag Along Notice) of: (i) its intention to Transfer some or all of the Tag Sale Interest to a third party; (ii) the proposed price that has been offered for the Tag Sale Interest (Sale Price); (iii) the name of the proposed Transferee; (iv) subject to clause 8.1(d), the date on which the sale to the proposed Transferee is proposed to be completed (Tag Along Sale Date); and (v) any other material terms of the proposed Transfer. (d) Tamboran Farmee must wait at least 20 Business Days from the date of service of the Tag Along Notice (Tag Along Option Period) to allow the Daly Waters Party holding an interest in the P2DA and/or Elliott the right to exercise its tag along option in accordance with clause 8.2 before completing the sale of any Tag Sale Interest. (e) If Tamboran Farmee wishes to assign a Tag Sale Interest to a Tamboran Affiliate, it must first procure that the relevant Tamboran Affiliate executes a deed of covenant with the relevant parties with a P2DA Interest under which the Tamboran Affiliate that is taking the assignment of the Tag Sale Interest agrees to be bound by the provisions of this Deed (to the extent of the interest being transferred) and, in particular, this clause 8. 8.2 Exercise of Tag along option (a) The Daly Waters Party holding an interest in the P2DA and/or Elliott, during the Tag Along Option Period, may serve a written notice (Tag Along Response Notice) on Tamboran Farmee specifying that Tamboran Farmee must use its reasonable

19 endeavours to cause the proposed Transferee to acquire the same proportion (as the Tamboran Farmee is transferring) of the Daly Waters Party holding an interest in the P2DA and Elliott’s aggregate P2DA Interest on no less favourable terms than those set out in the Tag Along Notice issued under clause 8.1(a). The Daly Waters Party holding an interest in the P2DA and Elliott must nominate, in the Tag Along Response Notice, which Daly Waters Parties are participating in the tag along and in what interest. (b) A Tag Along Response Notice is irrevocable once given. (c) If the Daly Waters Party holding an interest in the P2DA or Elliott does not give a Tag Along Response Notice within the Tag Along Option Period, then Tamboran Farmee may, at any time within 60 days after the Tag Along Option Period (or such longer period as is reasonably required to obtain any required governmental agency or third party approvals in respect of the Transfer), Transfer the Tag Sale Interest, at the Sale Price, to the proposed Transferee. (d) If the Daly Waters Party holding an interest in the P2DA and/or Elliott has given a Tag Along Response Notice, then Tamboran Farmee must not Transfer any of the Tag Sale Interest to the proposed Transferee unless the proposed Transferee also acquires the same proportion (as Tamboran Farmee is Transferring) of the Daly Waters Party holding an interest in the P2DA or Elliot’s P2DA Interest on the same terms and conditions in all material respects and at not less than the Sale Price. In the event that Tamboran Farmee proceeds with the sale, the parties must do all things and execute all documents (including, in the case of Tamboran, procuring that each applicable Tamboran Party does all things and executes all documents) as are reasonably necessary to effect the sale. (e) If DWE or Elliott has given a Tag Along Response Notice and, despite Tamboran Farmee’s reasonable endeavours, the proposed Transferee refuses to purchase DWE or Elliott’s nominated Tag Sale Interest, then Tamboran Farmee must not Transfer any of the Tag Sale Interest to the proposed Transferee (without again following the requirements of this clause 8 and issuing a new Tag Along Notice) and the Tag Along Response Notice lapses. (f) Tamboran Farmee and its Affiliates must not employ any device or technique or participate in any transaction designed to circumvent the provisions of this clause 8.2 (including transferring or agreeing to Transfer an indirect interest (including selling the shares in a Tamboran Party holding a P2DA Interest), or a synthetic or economic interest, in any P2DA Interest). 9. Approvals (a) DWE and Tamboran each agrees to take all reasonable steps required to procure that TB2 grants the P2DA JV the benefit of EMP ORI 11-3 in respect of 4 wells (and associated infrastructure) to be drilled within P2DA, on the following terms: (i) this right may only be exercised by the P2DA JV to the extent permitted by the terms of EMP ORI 11-3 and law; and (ii) the 4 wells are drilled by no later than 31 December 2027. (b) DWE and Tamboran each agrees to take all reasonable steps required to procure that TB2 grants the Dev B JV the benefit of EMP TAM 1-3 in respect of 4 wells (and associated infrastructure) to be drilled within the BCD Area, on the following terms:

20 (i) this right may only be exercised by the Dev B JV to the extent permitted by the terms of EMP TAM 1-3 and law; (ii) the 4 wells are drilled by no later than 31 December 2027; and (iii) such grant of the benefit of EMP TAM 1-3 in favour of the Dev B JV, will expire on and from the date of transfer of the Beetaloo Central E&A EMP to the Dev B JV, such that the benefit of EMP TAM 1-3 in respect of the 4 wells (and associated infrastructure), will revert back to TB2. (c) Tamboran, DWE and the Manager agree to take all steps required to procure that TB2: (i) submits an EMP over the BCD Area (Beetaloo Central E&A EMP) that covers the required scope (as reasonably notified by DWE to TB2 from time to time) and is otherwise similar in nature to the EMP ORI 11-3, for up to 12 (as notified by DWE to the Manager) exploration and/or appraisal wells (and associated infrastructure); and (ii) diligently progress that EMP application to approval and uses reasonable endeavours to ensure that the Beetaloo Central E&A EMP is approved as soon as reasonably practicable and within any statutory timeframes and, following approval of the Beetaloo Central E&A EMP, transfer the Beetaloo Central E&A EMP to the Dev B JV. (d) Following the transfer of the Beetaloo Central E&A EMP to the Dev B JV, DWE and Tamboran each agrees to take all reasonable steps required to procure that TB2 grants the P2DA JV the benefit of EMP ORI 11-3 in respect of any remaining wells in EMP ORI 11-3, and for the avoidance of doubt, the requirement set out in clause 9(a)(ii) to drill 4 wells by 31 December 2027 will cease to be a condition of that grant. (e) Subject to there being no adverse impact to TB2, DWE and Tamboran each agrees to take all reasonable steps required to procure that TB2 grants each of the P2DA JV and the Dev B JV the benefit of any AAPA Authority Certificates and Land Access Agreements that TB2 is a party to. (f) Unless otherwise agreed between DWE and Tamboran, the parties agree to give effect to this clause 9 by using reasonable endeavours to include the matters set out in this clause 9 in the New Area Transitional and Interface Deed entered into under the JOA in respect of the Dev B JOA and the P2DA JOA (each as a New Area JOA). 10.
