(ii)If an Indemnified Party gives notice to the Indemnifying Party pursuant to Section 9.3(a)(i) of the assertion of a Third Party Claim, then the Indemnifying Party shall be entitled to assume the defense of such Third Party Claim with counsel of its choosing that is reasonably acceptable to the Indemnified Party (it being agreed that the Indemnifying Party’s counsel as of the date hereof shall be reasonably acceptable to the Indemnified Party); provided, however, (i) the Indemnifying Party shall not be entitled to assume defense of a Third Party Claim if the Indemnified Party has one or more defenses that cannot be asserted by the Indemnifying Party and such inability would actually prejudice the Indemnified Party, (ii) the Indemnifying Party shall not be entitled to assume defense of a Third Party Claim if such claim is being brought by a Governmental Authority or seeks an injunction or provisional relief, and
(iii)as a condition to assuming the defense of such Third Party Claim, the Indemnifying Party must acknowledge and agree in writing that each Indemnified Party will be indemnified and held harmless hereunder with respect to the full amount of any and all Damages the Indemnified Party may suffer or incur arising out of or relating to the Third Party Claim. After notice from the Indemnifying Party to the Indemnified Party of its election to assume the defense of such Third Party Claim, the Indemnifying Party shall not be liable to the Indemnified Party under this Article IX for any fees of other counsel or any other expenses with respect to the defense of such Third Party Claim. If the Indemnifying Party assumes the defense of a Third Party Claim, then no compromise or settlement of such Third Party Claims may be effected by the Indemnifying Party without the Indemnified Party’s express written consent unless (i) there is no finding or admission of any wrongdoing by the Indemnified Party, (ii) the sole relief provided is monetary Damages that is paid in full by the Indemnifying Party, and (iii) the claim does not relate to Taxes. If notice is given to an Indemnifying Party of the assertion of any Third Party Claim and the Indemnifying Party does not, within fifteen (15) Business Days after the Indemnified Party’s notice is given, give notice to the Indemnified Party of the Indemnifying Party’s election to assume the defense of such Third Party Claim, then the Indemnifying Party shall be bound by any determination made in such Third Party Claim or any compromise or settlement reasonably effected by the Indemnified Party.
(iv)With respect to any Third Party Claim subject to indemnification under this Article IX: (i) both the Indemnified Party and the Indemnifying Party, as the case may be, shall keep the other fully informed of the status of such Third Party Claim and any related legal actions at all stages thereof where such other person is not represented by its own counsel,

82

Exhibit 10.4
and (ii) each Party agrees (at its own expense) to render to each other such assistance as a Party may

83

Exhibit 10.4
reasonably require of another and to cooperate in good faith with each other in order to ensure the proper and adequate defense of any Third Party Claim.
(v)With respect to any Third Party Claim subject to indemnification under this Article IX, the Parties agree to cooperate in such a manner as to preserve in full (to the extent possible) the confidentiality of all Confidential Information and the attorney-client and work-product privileges of the other Party. In connection therewith, each Party agrees that: (i) it will use its reasonable efforts, in respect of any Third Party Claim in which it has assumed or participated in the defense, to avoid production of Confidential Information (consistent with applicable Law and rules of procedure); and (ii) all communications between any Party and counsel responsible for or participating in the defense of any Third Party Claim shall, to the extent possible, be made so as to preserve any applicable attorney-client or work-product privilege.
(b)Direct Claims. In order for an Indemnified Party to be entitled to indemnification under this Article IX for a claim which has not arisen in respect of a Third Party Claim (a “Direct Claim”), the Indemnified Party shall give the Indemnifying Party prompt written notice thereof; provided, however, the failure to give such prompt written notice shall not relieve the Indemnifying Party of its indemnification obligations hereunder, except and only to the extent that the Indemnifying Party forfeits rights or defenses by reason of such failure or is otherwise materially prejudiced as a result of such failure. Such notice by the Indemnified Party shall describe the Direct Claim in reasonable detail, shall include copies of all material written evidence thereof and shall indicate the estimated amount, if reasonably practicable, of Damages that have been or may be sustained by the Indemnified Party. The Indemnifying Party shall have 60 days after its receipt of such notice to respond in writing to such Direct Claim. During such 60-day period, the Indemnified Party shall allow the Indemnifying Party and its professional advisors to investigate the matter or circumstance alleged to give rise to the Direct Claim and whether and to what extent any amount is payable in respect of the Direct Claim, and the Indemnified Party shall assist the Indemnifying Party’s investigation by giving such information and assistance as the Indemnifying Party or any of its professional advisors may reasonably request. If the Indemnifying Party does not so respond within such 60-day period, the Indemnifying Party shall be deemed to have rejected such claim, in which case the Indemnified Party shall be free to pursue such remedies as may be available to the Indemnified Party on the terms and subject to the provisions of this Agreement.
1.4 Survivability; Limitation on Actions.
(a)The representations and warranties of Boss Energy contained in this Agreement shall survive the Closing for the benefit of the enCore Parties as follows:

Claim shall have been given in writing before the expiry of that period, in which case the representation and warranty to which such notice applies shall survive in respect of that Third Party Claim until the final determination or settlement of that Third Party Claim.

(i) that are required to be performed at or prior to Closing in their entirety shall survive for three months after the Closing and (ii) that are required to be performed after the Closing shall survive the period stated for such covenants or agreements or, if no period is stated, until the last date on which any such covenants and agreements are performed or satisfied.

(ii)as to the representations and warranties contained in Section 3.17, until the expiration of the applicable statute of limitations under applicable tax Law plus sixty (60) days;
(iii)as to all other representations and warranties not listed in Section 9.4(c)(i) or Section 9.4(c)(ii), until one year following the Closing Date, unless a notice of a bona fide Third Party Claim shall have been given in writing before the expiry of that period, in which case the representation and warranty to which such notice applies shall survive in respect of that Third Party Claim until the final determination or settlement of that Third Party Claim.
(d)The covenants and agreements of enCore Energy contained in this Agreement (i) that are required to be performed at or prior to Closing in their entirety shall survive for three months after the Closing and (ii) that are required to be performed after the Closing shall survive the period stated for such covenants or agreements or, if no period is stated, until the last date on which any such covenants and agreements are performed or satisfied.
(e)The limitations on survivability of representations and warranties under Section 9.4(a) and Section 9.4(c) and of covenants and agreements under Section 9.4(b) and Section 9.4(d) shall not be applicable to the extent that a Party to which the limitation applies has committed fraud or made an intentional misrepresentation or omission in connection with this Agreement or the transactions contemplated herein.
(f)In no event shall any Indemnified Party be entitled to duplicate compensation with respect to the same Damage or Liability under more than one provision of this Agreement and the Ancillary Documents.

86

Exhibit 10.4

87

Exhibit 10.4
(g)The Indemnified Party shall take, and cause its Affiliates and Representatives to make, all commercially reasonable efforts to mitigate any Damages for which the Indemnifying Party may be liable under this Article IX upon becoming aware of any event or circumstance that would be reasonably expected to, or does, give rise thereto.
(h)Payments by the Indemnifying Party in respect of any Damages shall be limited to the amount of any liability or damage that remains after deducting therefrom any insurance proceeds and any indemnity, contribution or other similar payment received by the Indemnified Party in respect of any such Damages, net of any premium increases and associated costs.
(i)The enCore Parties shall not be required to indemnify the Boss Energy Indemnified Parties under Section 9.1 until the aggregate amount of all Damages in respect of indemnification under Section 9.1 exceeds $300,000 (the “Deductible”); provided, however, that any claims for indemnification by Boss Energy for a breach of any enCore Fundamental Representation or breach of the representations in Section 3.17 shall not be subject to the Deductible. The aggregate amount of all Damages for which the enCore Parties shall be liable to the Boss Energy Indemnified Parties pursuant to Section 9.1 shall not exceed $10,000,000 (the “Cap”); provided, however, that any indemnification by enCore Parties pursuant to Section 9.1 for breach of the representation in Section 3.17 or for breach of any enCore Fundamental Representation shall not be subject to, or otherwise considered in determining the Cap.
(j)Notwithstanding any other provision of this Agreement to the contrary, the aggregate amount of the Damages for which the enCore Parties shall be liable to the Boss Energy Indemnified Parties shall not exceed $60,000,000.
(k)Notwithstanding the foregoing, the limitations set forth in Section 9.4(i) and Section 9.4(j) shall not apply to Damages based upon, arising out of, or with respect to any of the Ancillary Agreements.
(l)If either (A) Boss becomes aware of a breach by enCore of one or more of the Qualified Representations and Warranties which would also constitute a breach of the same or similar representations or warranties by ERF under the EF Acquisition Agreement and notifies enCore US of the same, or (B) enCore US becomes aware of any such breach, then enCore, if it believes in good faith it has an indemnification claim against ERF under the EF Acquisition Agreement, shall use reasonable best efforts to pursue that claim against ERF. To the extent the enCore Parties receive any indemnification proceeds from the Seller under the EF Acquisition Agreement, and but for the proviso to the first sentence of the preamble to Article III, any representation or warranty in Article III would have been inaccurate, at or after the Closing, enCore shall remit 30% of such proceeds to Boss Energy US.
1.5 Exclusive Remedies. The Parties acknowledge and agree that their sole and exclusive post-Closing monetary remedy with respect to any and all claims (other than claims arising from Fraud) for any breach of any representation, warranty, covenant, agreement or obligation set forth herein or otherwise relating to the subject matter of this Agreement, shall be pursuant to the indemnification provisions set forth in this Article IX. In furtherance of the

88

Exhibit 10.4
foregoing, each Party hereby waives, to the fullest extent permitted under Law, any and all rights,

89

Exhibit 10.4
claims and causes of action for any breach of any representation, warranty, covenant, agreement or obligation set forth herein or otherwise relating to the subject matter of this Agreement it may have against the other Parties hereto and their Affiliates and each of their respective representatives arising under or based upon any Law, except pursuant to the indemnification provisions set forth in this Article IX. Nothing in this Section 9.5 shall limit any Person’s right to seek and obtain any equitable relief to which any Person shall be entitled or to seek any remedy on account of any Party’s Fraud. For the avoidance of doubt, nothing in this Section 9.5 shall prevent a Party prior to the Closing from bringing a claim for a pre-Closing breach of a covenant.
ARTICLE X TAX MATTERS
1.1 Tax Indemnity. The enCore Parties shall indemnify, defend and hold harmless the Boss Energy Indemnified Parties from and against any and all Damages relating to or arising out of any and all Taxes of an Operating Company or Newco (or the non-payment thereof) (i) with respect to all periods ending on or prior to the Closing Date (a “Pre-Closing Period”), (ii) with respect to any period beginning before the Closing Date and ending after the Closing Date (a “Straddle Period”), but only with respect to the portion of such period up to and including the Closing Date (such portion, a “Pre-Closing Partial Period”), (iii) payable as a result of a breach of any representation or warranty set forth in Section 3.17, and (iv) payable in connection with the transactions contemplated by this Agreement. The enCore Parties shall also jointly and severally indemnify, defend and hold harmless the Boss Energy Indemnified Parties from and against any and all Damages relating to or arising out of Taxes of any person other than an Operating Company by reason of the application of Treasury Regulation §1.1502-6 (or any similar provision of state, local, or foreign Law) or the imposition of transferee liability, successor liability, contractual liability or other basis of liability in each case attributable to any Pre-Closing Period or Pre-Closing Partial Period. For avoidance of doubt, Section 9.1 and the limitations set forth in Section 9.4 shall not apply to indemnification for Losses relating to or arising out of Taxes or for breaches of the representations and warranties set forth in Section 3.17.
1.2 Apportionment of Taxes. In the case of Taxes (other than Transfer Taxes) that are payable with respect to any Straddle Period, the portion of any such Tax that is attributable to a Pre-Closing Partial Period shall be:
(a)in the case of income Taxes or any other Taxes resulting from, or imposed on, sales, receipts, uses, transfers or assignments of property or other assets, payments or accruals to other persons (including, without limitation, wages), or any other similar transaction or transactions, the amount that would be payable for the Pre-Closing Partial Period if the Company closed its books as of the close of business on the Closing Date and filed a separate Tax Return with respect to such Taxes solely for the Pre-Closing Partial Period (for purposes of this clause (a), any item determined on an annual or periodic basis (including amortization and depreciation deductions and the effects of graduated rates) shall be allocated to the Pre-Closing Partial Period based on the relative number of calendar days in such period as compared to the number of calendar days in the entire Straddle Period); and

90

Exhibit 10.4
(b)in the case of all other Taxes, an amount equal to the amount of Taxes for the entire Straddle Period multiplied by a fraction the numerator of which is the number of calendar

91

Exhibit 10.4
days in the Pre-Closing Partial Period and the denominator of which is the number of calendar days in the entire Straddle Period.
1.3 Filing of Tax Returns.
(a)The enCore Parties, at the expense of the enCore Parties, shall prepare or cause to be prepared and timely file or cause to be timely filed all Tax Returns required to be filed by an Operating Company on or before Closing Date (each, an “enCore Return”). All such enCore Returns shall be prepared in a manner consistent with the past practices of the Company except as required by applicable Law or change in fact. The enCore Parties shall deliver or cause to be delivered a copy of each such enCore Return to Boss Energy within five (5) days after filing.
(b)From and after the Closing Date, all Tax Returns of the Operating Companies and Newco will be prepared and filed in accordance with the LLC Agreement.
1.4 Tax Treatment and Allocation of Purchase Price. Solely for income Tax purposes, the Parties will treat Boss US’s purchase of the Newco Membership Interests according to Revenue Ruling 99-5, Situation 1, as Boss US’s purchase of a thirty percent (30%) interest in each of the Operating Companies’ assets, followed immediately by Boss US’s and enCore US’s contribution of their respective interests in such assets to a partnership in exchange for ownership interests in the partnership (the “Intended Tax Treatment”). The Parties agree that the Purchase Price, and any other amounts treated as taxable consideration for the New Membership Interests for U.S. federal income Tax purposes (collectively, the “Allocable Consideration”), will be allocated among the assets of the Operating Companies that Boss US is deemed to purchase from enCore US consistent with the allocation prepared after the closing of transaction under the EF Acquisition Agreement). The Parties acknowledge that, under Section 1060 of the Code, Boss US and enCore US must report information regarding the allocation of the Allocable Consideration by attaching IRS Form 8594 to their federal income Tax Returns for the Taxable period which includes the Closing Date. The Parties agree that they shall report for all federal income tax purposes in a manner consistent with the Intended Tax Treatment, unless otherwise required by a determination within the meaning of Section 1313(a) of the Code. The allocation of the Allocable Consideration shall be revised to take into account subsequent adjustments to the Purchase Price (e.g., any indemnification payments).

EACH PARTY ACKNOWLEDGES THAT IT HAS BEEN INFORMED BY THE OTHER PARTIES THAT THIS SECTION 11.4(c) CONSTITUTES A MATERIAL INDUCEMENT UPON WHICH SUCH PARTY IS RELYING AND WILL RELY IN ENTERING INTO THIS AGREEMENT, THE ANCILLARY DOCUMENTS, AND ANY OTHER AGREEMENTS RELATING HERETO OR CONTEMPLATED HEREBY OR THEREBY.
1.5 Waivers. Any failure by a Party to comply with any of its obligations, agreements or conditions herein contained may only be waived by the Party to whom such compliance is owed by a written instrument signed by such Party and expressly identified as a waiver, but not in any other manner. No waiver of, consent to a change in, or any delay in timely exercising any rights arising from, any of the provisions of this Agreement shall be deemed or shall constitute a waiver of, or consent to a change in, other provisions hereof (whether or not similar), nor shall such waiver constitute a continuing waiver unless otherwise expressly provided.

Prior to the Closing Date, no Party shall assign all or any part of this Agreement, nor shall any Party assign or delegate any of its rights or duties hereunder, without the prior written consent of the other Parties (which consent may not be unreasonably withheld) and any assignment or delegation made without such written consent shall be void.

1.12 Specific Performance and Certain Remedies. enCore acknowledges and agrees that the breach of this Agreement by the enCore Partis would cause irreparable damage to Boss Energy, Boss Energy would not have an adequate remedy at law with respect to such breach, damages would be difficult to determine, and Boss Energy shall be entitled to specific performance of the terms hereof and immediate injunctive relief, without the necessity of proving the inadequacy of money damages as a remedy. Such remedies shall, however, be cumulative and not exclusive and shall be in addition to any other remedies which Boss Energy may have under this Agreement or otherwise in connection with such a breach. Boss Energy shall not be required to provide any bond or other security in connection with seeking any specific performance or other equitable remedy to enforce specifically the terms and provisions of this Agreement. Each of the Parties expressly disclaims that it is owed any duties not expressly set forth in this Agreement, and waives and releases any and all tort claims and causes of action that may be based upon, arise out of or relate to this Agreement, or the negotiation, execution or performance of this Agreement.

(c)Without limiting the foregoing, Boss Energy acknowledges and agrees, that it has conducted to its satisfaction its own independent investigation of the transactions contemplated by this Agreement and, in making its determination to enter into this Agreement and proceed with the transactions contemplated by this Agreement, it has relied solely on the results of such independent investigation and the representations and warranties expressly set forth in Article III, respectively.
