    Section 4.1     Organization; Good Standing; Qualification. Investor will be, following the transactions contemplated by Section 5.16, a Delaware entity, duly formed, validly existing and in good standing under the Laws of the jurisdiction of
        its formation and has all requisite power and authority to own, lease or otherwise hold its properties and assets, to carry on its business as presently conducted and to execute, deliver and perform the obligations under this Agreement.  Investor
        Parent is a company duly organized, validly existing and in good standing under the Laws of South Africa and has all requisite power and authority to carry on its business as presently conducted and to execute, deliver and perform the obligations
        under this Agreement.  Investor is duly qualified to transact business and is in good standing in each jurisdiction in which the failure to so qualify would have a material adverse effect on Investor or would reasonably be expected to hinder
        Investor’s ability to consummate the transactions contemplated by this Agreement or any other Transaction Document to which Investor is or will be a party.

    

    

    Section 4.2      Authorization. All organizational action of, or with respect to, Investor, Investor Parent and their relevant Affiliates, if applicable, required to be taken in order to authorize  the due execution of, delivery of and performance by
        Investor, Investor Parent and such Affiliates of their obligations under this Agreement and each other Transaction Document to which Investor, Investor Parent or any such Affiliate is or will be a party, has been duly and validly taken by all
        necessary Persons.  This Agreement and each other Transaction Document executed and delivered or to be executed and delivered in accordance with the terms provided herein or therein by Investor, Investor Parent or their relevant Affiliates,
        assuming the due authorization, execution and delivery of this Agreement and such other Transaction Document by each other party thereto, constitutes (or shall constitute when executed and delivered, as may be applicable) the valid and legally
        binding obligation of Investor, Investor Parent and their relevant Affiliates, enforceable against Investor, Investor Parent and their relevant Affiliates in accordance with the terms of this Agreement or of such Transaction Document, subject to
        Creditors’ Rights and Equitable Principles.

    

    

    
      30

      
        


    

    Section 4.3     No Conflicts; Consents and Approvals. Subject to obtaining the consents and approvals referred to in Section 2.2(a), the execution, delivery and performance of this Agreement and each other Transaction Document to which
        Investor or any of its Affiliates is or will be a party and the consummation of the transactions contemplated by this Agreement and by each other Transaction Document to which Investor or any of its Affiliates is or will be a party does not and
        will not (i) violate or result in a breach of the Governing Documents of Investor or such Affiliate; or (ii) assuming the accuracy of the representations made by the Company and ioneer Parent in this Agreement and in the A&R LLC Agreement, and
        other than such notices that have already been given, filings that have already been made and consents that have already been obtained, require the sending of any notice to, making of any filing with or obtaining of any consent or approval from any
        Governmental Authority except, in the case of clause (ii), (x) for filings pursuant to applicable securities laws or (y) as would not be materially adverse to Investor or Investor Parent, including its ability to perform its obligations
        under this Agreement or any of the other Transaction Documents to which it is or will be a party, or to the Project.

    

    

    Section 4.4      Compliance Matters. No part of the funds used by Investor to pay the Initial Cash Consideration, any Subsequent Funding Obligation or other payments to the Company or to fund all or any part of Investor’s capital commitment has been, is, or
        will be, directly or indirectly derived from, or related to, any activities that contravene applicable Laws, including Anti-Corruption Laws, Anti-Money Laundering Laws and Export Controls and Economic Sanctions Laws.  Investor acknowledges that
        Export Controls and Economic Sanctions Laws prohibit dealing with individuals or entities in Embargoed Countries and prohibit or restrict, among other things as applicable, the engagement in transactions with, and the provision of services to
        Sanctioned Persons.  None of (a) Investor; (b) any Person Controlling or Controlled by Investor; (c) any Person that owns, directly or indirectly, 50% or more of Investor or any Persons that own, in the aggregate, directly or indirectly, 50% or
        more of Investor; or (d) any Person for whom Investor is acting as agent or nominee in connection with the transactions contemplated by this Agreement (collectively, the “Investor Parties”)

        is, or has been during the last *** , either (i) a Sanctioned Person, (ii) a Person with whom transactions are restricted or prohibited under Export Controls and Economic Sanctions Laws, or (iii) located, organized, or resident in an Embargoed
        Country or a Cuban national wherever located.  None of the Investor Parties is a senior foreign political figure or politically exposed person (as such term is defined by the Financial Action Task Force on Money Laundering) or any immediate family
        member or close associate of a senior foreign political figure or politically exposed person.  Investor is not a “foreign person” as that term is defined in 31 C.F.R. § 800.216.

    

    

    
      31

      
        


    

    Section 4.5       Private Placement Matters. Investor understands that the Acquired Units are not and will not be registered under the Securities Act or the laws of any state or other applicable jurisdiction.  Investor is aware and understands that the offering
        and sale of the Acquired Units are intended to be exempt from registration under the Securities Act by virtue of Section 4(a)(2) of the Securities Act and/or the provisions of regulations promulgated thereunder, including Rule 506(d) of Regulation
        D.  Investor is an “accredited investor” as defined in Rule 501(a) of Regulation D, as amended, under the Securities Act.  Investor recognizes that there is no established trading market for the Acquired Units and it is extremely unlikely that any
        public market for the Acquired Units will develop.  Investor understands and agrees that the Acquired Units must be held indefinitely unless the Acquired Units are subsequently registered with the Securities and Exchange Commission under the
        Securities Act and qualified by state authorities, where required, under the laws of other applicable jurisdictions, or unless an exemption from registration is available.  Investor further understands and agrees that no federal or state authority
        has approved or disapproved the Acquired Units, passed upon or endorsed the merits of the offering thereof, or made any finding or determination as to the fairness of the Acquired Units for investment.  Investor also understands that the Acquired
        Units are being offered and sold in reliance on specific exemptions from the registration requirements of federal and state securities laws and that the Company is relying upon the truth and accuracy of the representations, warranties, agreements,
        acknowledgments and understandings set forth herein in order to determine the applicability of such exemptions and the suitability of Investor to acquire the Acquired Units.  Investor is acquiring the applicable Acquired Units for its own account
        and not with an intent to transfer or otherwise resell or distribute any part thereof.  Investor is not subject to any of the “bad actor” disqualifying events set forth in Rule 506(d) of Regulation D under the Securities Act.  Investor has
        sufficient knowledge and experience to evaluate the risks and merits of its investment in the Company and to make an informed investment decision.

    

    

    Section 4.6        Investigation.

    

    

    (a)       Investor acknowledges that it has made an independent decision to enter into this Agreement and the Transaction Documents, and that, in making its decision, Investor has relied solely upon
      any independent investigations made by Investor, its Affiliates and/or its Representatives and on the representations and warranties expressly set forth in this Agreement and in the Transaction Documents.  Investor acknowledges that none of the other
      Parties, their Affiliates or any of their respective officers, directors, managers, employees, Representatives or other agents has made, or is making, a recommendation or providing investment advice to Investor regarding an investment in the Company
      or has provided any representations or warranties, other than those representations and warranties set forth in Article III.  To the extent Investor has required or desired any advice in connection with the offering of the Acquired Units or
      entering into this Agreement or any assistance in understanding or evaluating an investment in the Company, Investor has engaged its own financial, legal, tax, accounting, regulatory and other advisors, and has not expected or received any such
      advice or assistance from the other Parties, their Affiliates or any of their respective Representatives.  Investor and any independent advisors engaged by Investor have conducted their own analysis and due diligence to the full extent they have
      deemed such action necessary, and, based upon such independent analysis and due diligence, Investor has made its own independent determination with respect to the matters contemplated hereby.

    

    

    
      32

      
        


    

    (b)      Investor acknowledges that no Party is making any representation or warranty as to the prospects, financial or otherwise, related to the Company and that any projections, estimates or
      forecasts of future results or events provided by or on behalf of the Company are subject to uncertainty and to the assumptions used in their preparation.  Investor agrees that it is acquiring the Acquired Units based on Investor’s due diligence,
      inspection, examination and determination with respect thereto as to all matters, and without reliance upon any express or implied representations or warranties of any nature, whether in writing, orally or otherwise, made by or on behalf of or
      imputed to the other Parties or their respective Affiliates or any of their respective Representatives as to the accuracy or completeness of any of the information (including projections, estimates or forecasts of future results or events) provided
      or made available to Investor or its Representatives, except as expressly set forth in the Transaction Documents.  Investor acknowledges and agrees that, except as expressly set forth in the Transaction Documents, none of the other Parties or their
      respective Affiliates or any of their respective Representatives has or shall have any liability or responsibility whatsoever to Investor or any of its Representatives on any basis (including in contract or tort, under applicable Law or otherwise)
      based upon any information (including projections, estimates or forecasts of future results or events) provided or made available, or statements made, to Investor or its Representatives.

    

    

    Section 4.7       Brokers’ Fees.  Based on arrangements made by Investor or any of its Affiliates, no Group Company will have any liability or obligation to pay any fees or commissions to any broker, finder or agent as a result of the transactions
        contemplated by the Transaction Documents.

    

    

    Section 4.8       Sufficiency of Funds. Investor Parent has, and will cause Investor to have, at all times prior to the Aggregate Capital Commitment being reduced to zero Dollars ($0.00), sufficient available funds to deliver the Initial Cash Consideration
        at the Closing and any Subsequent Funding Obligation, and to pay any and all costs and expenses required to be paid by Investor at the Closing.

    

    

    
      33

      
        


    

    Section 4.9      Anti-Corruption Laws; Anti-Money Laundering Laws. During the *** preceding the Execution Date, Investor and its Affiliates have been in compliance with applicable Anti-Corruption Laws and Anti-Money Laundering Laws, and Investor, its
        Affiliates and their respective officers, directors, employees, and to Investor’s knowledge, its and its Affiliates’ respective agents, consultants, and other representatives representing Investor or its Affiliates have not made, given, offered,
        authorized, or promised to make, give, offer or authorize the payment of any money, commission, reward, gift, hospitality, entertainment, inducement (including any facilitation payments) or anything else of value, directly or indirectly, to any
        Government Official or any person acting for or on behalf of any Government Official for the purpose of obtaining or retaining business or favorable governmental action or to otherwise secure any improper advantage in violation of the applicable
        Anti-Corruption Laws. The operations of Investor and, to the knowledge of Investor, its Affiliates are and have been conducted in compliance with all applicable financial recordkeeping and reporting requirements and Anti-Money Laundering Laws, and
        no Claim by or before any Governmental Authority against Investor or any of its Affiliates and pertaining to Anti-Money Laundering Laws is pending or, to the knowledge of Investor, threatened.

    

    

    Section 4.10    Litigation. As of the Execution Date, there is no Claim pending or, to the knowledge of Investor, currently threatened by any Person against Investor, or any of its assets or properties, or involving the Project by or before any Governmental
        Authority, or that seeks an Order restraining, enjoining or otherwise prohibiting any of the transactions contemplated by this Agreement or any Transaction Document or that would reasonably be expected to materially and adversely affect, restrict
        or hinder completion of the Project or result in a material Liability of Investor any.  As of the Execution Date, there is no Claim pending by Investor, or which Investor has commenced preparations to initiate, against any other Person.

        States person, and will deliver to the Ioneer Members or the Company a valid IRS Form W-9, and (ii) as a result of Investor’s ownership interest in the Company, the property of the Company or any entity in which the Company owns equity interests
        will not be treated as owned, leased by, leased to, or otherwise used by (A) an organization that is exempt from tax imposed by chapter 1 of the Code, (B) the United States, any state (including the District of Columbia) or political subdivision

        promptly notify the Party from whom indemnification is sought (the “Indemnifying Party”) of the existence of the claim and, when known, the facts constituting the basis for such claim; provided, that, no delay in or failure to give such notice shall relieve the Indemnifying Party of its obligations pursuant to this Article VI except as otherwise provided in Section 6.3(a). The
        obligations and liabilities of ioneer Parent to indemnify the Investor Group under Section 6.2(a) or of Investor to indemnify the Company Group under Section 6.2(b), resulting from the assertion of any Damages by third parties (a “Third Party Claim”), shall be subject to the following terms and conditions:

    

    

    (a)       The Indemnified Party will give the Indemnifying Party prompt notice of any such Third Party Claim, including the specific details of and specific basis under this Agreement for its claim
      (a “Claims Notice”) and shall enclose a copy of all papers (if any) served to the Indemnified Party with respect to the Third Party Claim; provided,
      however, that failure to provide such Claim Notice will not relieve the Indemnifying Party of its obligations under this Agreement unless and to the extent such failure results in insufficient time being
      available to permit the Indemnifying Party to effectively defend against such Third Party Claim or otherwise actually and materially prejudices the Indemnifying Party’s ability to defend against such Third Party Claim.  In the event that the claim
      for indemnification is based upon an inaccuracy or a breach of a representation, warranty, covenant or agreement, the Claim Notice shall specify the representation, warranty, covenant or agreement that was purportedly inaccurate or breached.

    

    

    
      46

      
        


    

    (b)      In the case of a claim for indemnification based upon a Third Party Claim, the Indemnifying Party shall have *** from its receipt of the Claim Notice to notify the Indemnified Party whether
      it admits or denies its obligation to defend and indemnify the Indemnified Party against such Third Party Claim at the sole cost and expense of the Indemnifying Party.  The Indemnified Party is authorized, prior to and during such *** period, at the
      expense of the Indemnifying Party, to file any motion, answer or other pleading that it shall deem necessary or appropriate to protect its interests or those of the Indemnifying Party and that is not prejudicial to the Indemnifying Party.

    

    

    (c)      As to a claim for indemnification based upon a Third Party Claim, except as set forth in Section 6.3(f), the Indemnifying Party shall be, subject to the limitations set forth in this
      Section 6.3, entitled to assume full control of the defense of such Third Party Claim and proceedings, including any compromise or settlement thereof.  If requested by the Indemnifying Party, the Indemnified Party agrees to cooperate in
      contesting any Third Party Claim which the Indemnifying Party elects to contest.

    

    

    (d)     Notwithstanding anything to the contrary in this Section 6.3: an Indemnified Party shall have the right, at its own cost and expense, to participate in (but not control) the defense,
      compromise or settlement of such claim (except if there exists a conflict of interest that could make it inappropriate under applicable standards of professional conduct for the Indemnifying Party and the Indemnified Parties to have common counsel
      such participation, including the reasonable fees and expenses of separate counsel, shall be at the expense of the Indemnifying Party); the Indemnifying Party shall not, without the written consent of the Indemnified Party, settle or compromise any
      claim or consent to the entry of any judgment (x) that does not include as an unconditional term thereof the giving by the claimant or the plaintiff to the Indemnified Party a release from all liability in respect of such claim, or that involves a
      finding of or admission of criminal wrongdoing, or (y) as a result of which injunctive or other equitable relief, or the payment of any monetary damages as to which the Indemnified Party shall not be paid in full by the Indemnifying Party, would be
      imposed against the Indemnified Party.

    

    

    (e)      If the Indemnifying Party fails to diligently prosecute, indemnify against or settle such Third Party Claim (as finally determined by a court of competent jurisdiction), then the Indemnified
      Party shall have the right to defend against the Third Party Claim at the sole cost and expense of the Indemnifying Party, with counsel of the Indemnified Party’s choosing, subject to the right of the Indemnifying Party to assume the defense of the
      Third Party Claim at any time prior to settlement or final determination thereof.  If settlement has been offered and the Indemnifying Party has not yet assumed the defense of such Third Party Claim, the Indemnified Party shall send written notice to
      the Indemnifying Party of any proposed settlement and the Indemnifying Party shall have the option for *** following receipt of such notice to (i) admit in writing its obligation to indemnify the Indemnified Party from and against the liability and
      consent to such settlement, (ii) if liability is so admitted, reject, in its reasonable judgment, the proposed settlement, or (iii) deny liability.  Any failure by the Indemnifying Party to respond to such notice shall be deemed to be an election
      under subsection (iii) above.

    

    

    
      47

      
        


    

    (f)       With respect to any claim for indemnification based on a Third Party Claim for Taxes assessed directly against an Indemnified Party, the Indemnified Party shall control the defense of such
      Third Party Claim and proceedings and shall keep the Indemnifying Party informed on such Third Party Claim and proceedings and will consider in good faith any comments made by the Indemnifying Party, provided that the Indemnified Party shall not
      settle or compromise such Third Party Claim without the consent of the Indemnifying Party (not to be unreasonably withheld).

    

    

    Section 6.4      Available Remedies.  Notwithstanding anything herein to the contrary, but subject to the other provisions and limitations of this Article VI:

    

    

    (a)     In no event shall ioneer Parent’s or Investor’s (as applicable) aggregate liability with respect to this Article VI in respect of Damages exceed *** (the “Total Consideration”).

    

    

    (b)      Other than in connection with a breach of any Fundamental Representation or breach of the representations and warranties in Section 3.15 (Contribution of Assets) or of any covenant,
      neither ioneer Parent nor Investor, respectively, shall have any liability to any Person under Section 6.2(a) or Section 6.2(b), respectively, in respect of Damages arising from a breach of any representation or warranty for
      which ioneer Parent or Investor has agreed to provide indemnification (i) for any individual Damage unless the amount with respect to such Damage meets or exceeds *** (the “Individual Indemnity
        Threshold”), (ii) unless and until the aggregate amount of all Damages incurred by all Persons seeking indemnification hereunder collectively meets or exceeds *** of the Total Consideration (the “Threshold Amount”), in which event ioneer Parent or Investor (as applicable) shall be liable for Damages from the first dollar and not merely the excess over such amount, and (iii) other than in connection with a breach of the
      representations and warranties set forth in Section 3.15 (Contribution of Assets), for aggregate Damages incurred by all Persons seeking indemnification hereunder in excess of *** of the Total Consideration (the “Cap Amount”).  For the avoidance of doubt, none of the limitations set forth in this Section 6.4(b) shall apply to Damages arising from a breach of a covenant or other obligation under this Agreement.

    

    

    Section 6.5      Mitigation.  Without prejudice to the Indemnifying Party’s obligation to indemnify hereunder, the Parties agree that each Indemnified Party shall take commercially reasonable efforts to mitigate any Damages for which such Indemnified Party
        may have any recourse under this Article VI; provided that no such Indemnified Party shall be required to take any action or refrain from taking any action that is contrary to any applicable Permit,
        Contract or Law.

    

    

    
      48

      
        


    

    Section 6.6     Recovery.  In the event that any Damages are suffered by any Indemnified Party for which any such Indemnified Party is entitled to indemnification under this Article VI and such Indemnified Party has actually been fully indemnified
        or reimbursed or compensated, directly or indirectly, by an Indemnifying Party with respect to all such Damages (including fees and expenses incurred in obtaining such indemnification), then such Damages shall be deemed to have been fully satisfied
        and shall no longer exist and, therefore, any further recovery by such Indemnified Party or any other Indemnified Party from any Indemnifying Party for such Damages would constitute an unintended “double” recovery and shall be prohibited under this
        Agreement.

    

    

    Section 6.7       Calculation of Losses.

    

    

    (a)       The amount of any Damages for which any Indemnified Party is finally determined to be entitled to indemnification under this Article VI shall be reduced by (i) any insurance
      proceeds actually received by such Indemnified Party (together with any related insurance proceeds actually received by any Affiliate of such Indemnified Party) with respect to such Damages, (ii) any actual cash Tax savings or attributes arising from
      or related to such Damages, and (iii) indemnification or reimbursement payments actually received by the Investor Group or the Company Group (as applicable) from third parties with respect to such Damages.

    

    

    (b)       If any matter giving rise to a claim of Damages by any Indemnified Party pursuant to this Article VI is reasonably likely to be covered by any insurance policy of any Party or its
      Affiliates, then, without prejudice to the Indemnifying Party’s indemnification obligation hereunder, such Parties shall reasonably cooperate with one another and use commercially reasonable efforts to obtain reimbursement for such Damages under such
      insurance policy; provided further that, if any insurance proceeds are thereafter received by an Indemnified Party with respect to Damages that have been satisfied directly by an Indemnifying Party, then such
      Indemnified Party shall promptly reimburse each such Indemnifying Party the amount of any such payment made directly by such Indemnifying Party (up to the amount of the insurance proceeds actually received by such Indemnified Party and after
      deducting any reasonable costs or expenses incurred in securing such insurance proceeds).

    

    

    Section 6.8       Exclusive Remedy; Waiver.

    

    

    (a)       NOTWITHSTANDING ANYTHING TO THE CONTRARY IN THIS AGREEMENT, FROM AND AFTER THE CLOSING, EXCEPT AS PROVIDED IN THIS ARTICLE VI,  EXHIBIT E OR SECTION 8.9, NO PARTY
      SHALL HAVE ANY LIABILITY, AND NO INDEMNIFIED PARTY SHALL MAKE ANY CLAIM, FOR ANY DAMAGES (AND THE PARTIES HEREBY WAIVE ANY RIGHT OF CONTRIBUTION AGAINST EACH OTHER AND THEIR RESPECTIVE AFFILIATES) UNDER, ARISING OUT OF OR RELATING TO THIS AGREEMENT,
      WHETHER BASED IN CONTRACT, TORT, STRICT LIABILITY, OTHER LAWS OR OTHERWISE.

    

    

    
      49

      
        


    

    (b)       NOTWITHSTANDING ANYTHING TO THE CONTRARY IN THIS AGREEMENT, NO PARTY SHALL BE LIABLE UNDER THIS AGREEMENT FOR LOST PROFITS OR CONSEQUENTIAL, SPECIAL, EXEMPLARY, PUNITIVE, INDIRECT, REMOTE
      OR SPECULATIVE DAMAGES, WHETHER BASED IN CONTRACT, TORT, STRICT LIABILITY, OTHER LAW OR OTHERWISE; PROVIDED, HOWEVER, THAT THIS SECTION 6.8(B) SHALL NOT LIMIT
      AN INDEMNIFIED PARTY’S RIGHT TO RECOVERY UNDER THIS ARTICLE VI FOR ANY SUCH DAMAGES TO THE EXTENT SUCH INDEMNIFIED PARTY IS REQUIRED TO PAY SUCH DAMAGES TO A THIRD PARTY IN CONNECTION WITH A MATTER FOR WHICH SUCH INDEMNIFIED PARTY IS
      OTHERWISE ENTITLED TO INDEMNIFICATION UNDER THIS ARTICLE VI.

    

    

    (a)    NOTWITHSTANDING ANYTHING IN THIS AGREEMENT TO THE CONTRARY, NO MANAGER, DIRECTOR, OFFICER, REPRESENTATIVE OR AFFILIATE OF ANY PARTY (OR ANY REPRESENTATIVE OF ANY SUCH AFFILIATE) IN SUCH
      CAPACITY SHALL HAVE ANY PERSONAL LIABILITY TO ANY PARTY AS A RESULT OF THE BREACH OF ANY REPRESENTATION, WARRANTY, COVENANT, AGREEMENT OR OBLIGATION IN THIS AGREEMENT (FOR THE AVOIDANCE OF DOUBT, WITH RESPECT TO ANY MATTER EXPRESSLY AGREED TO IN
      WRITING BY SUCH MANAGER, DIRECTOR, OFFICER, REPRESENTATIVE OR AFFILIATE AS A PRINCIPAL AND NOT IN SUCH PERSON’S CAPACITY AS A MANAGER, DIRECTOR, OFFICER, REPRESENTATIVE OR AFFILIATE OF A PARTY).  EACH PARTY HEREBY WAIVES, AND SHALL CAUSE EACH OF ITS
      AFFILIATES TO WAIVE (TO THE EXTENT PERMITTED BY LAW), ANY CLAIMS OR OTHER METHOD OF RECOVERY, WHETHER BASED IN CONTRACT, TORT OR STRICT LIABILITY, OR UNDER APPLICABLE LAW, AGAINST ANY SUCH MANAGER, DIRECTOR, OFFICER, REPRESENTATIVE OR AFFILIATE
      RELATING TO THE TRANSACTIONS CONTEMPLATED BY THIS AGREEMENT IN SUCH CAPACITY  (FOR THE AVOIDANCE OF DOUBT, WITH RESPECT TO ANY MATTER EXPRESSLY AGREED TO IN WRITING BY SUCH MANAGER, DIRECTOR, OFFICER, REPRESENTATIVE OR AFFILIATE AS A PRINCIPAL AND
      NOT IN SUCH PERSON’S CAPACITY AS A MANAGER, DIRECTOR, OFFICER, REPRESENTATIVE OR AFFILIATE OF A PARTY).

    

    

    Section 6.9       Tax Treatment.  Any indemnity payment made pursuant to this Agreement will be
      treated as an adjustment to the capital contributions of the Parties to the Company for Tax purposes, unless an audit or other administrative or judicial action or Law causes any such payment not to constitute an adjustment to the capital
      contributions for U.S. federal income tax purposes.

      time of such termination, such Party is in material breach of any of its covenants contained herein such as would result in any of the closing conditions set forth in Section 2.2, 2.3 or 2.4 not being satisfied, and provided, further, however, that if all the conditions to Closing have been satisfied or waived (other than Section 2.2(b)(ii)(A) or (B)), the Longstop Date shall automatically be extended once
      (and not more than once) for an additional ***;

    

    

    (b)       by mutual written consent of the Parties;

    

    

    (c)      by Investor in the event of a Parent Change of Control of ioneer Parent or by ioneer Parent or the Company in the event of a Parent Change of Control of Investor Parent, in each case,
      exercisable by the terminating Party providing notice to the other Party no later than *** after receipt of a notice from the non-terminating Party that the applicable Parent Change of Control has been consummated;

    

    

    (d)      by any Party if any Governmental Authority of competent jurisdiction shall have issued any order, decree, ruling or injunction or taken any other action permanently restraining, enjoining or
      otherwise prohibiting the consummation of the transactions contemplated by this Agreement and such order, decree, ruling or injunction or other action shall have become final and nonappealable, or if there shall be adopted following the Execution
      Date any Law that makes consummation of the transactions contemplated by this Agreement illegal or otherwise prohibited;

    

    

    (e)     by Investor if any of the representations or warranties of the Company or ioneer Parent was or becomes inaccurate or any breach or breaches by the Company or ioneer Parent of any covenant or
      other agreement of the Company or ioneer Parent contained in this Agreement occurs and as a result of any such breach or inaccuracies, any condition set forth in Section 2.3 would not then be capable of being satisfied, and any such breaches
      or inaccuracies are not curable, or, if curable have not been cured within *** Business Days after Investor sends notice of such breach to the Company; provided, however,
      that Investor shall not have the foregoing right to terminate if, at the time of such termination, Investor is in material breach of any of its representations, warranties or covenants contained herein such as would result in any of the closing
      conditions set forth in Section 2.4 not being satisfied;

    

    

    
      51

      
        


    

    (f)      by the Company or ioneer Parent if any of the representations or warranties of Investor was or becomes inaccurate or any breach or breaches by Investor of any covenant or other agreement of
      Investor contained in this Agreement occurs and as a result of any such breach or inaccuracies, any condition set forth in Section 2.4 would not then be capable of being satisfied, and any such breaches or inaccuracies are not curable, or, if
      curable have not been cured within *** Business Days after the Company sends notice of such breach to Investor; provided, however, that neither Company nor ioneer
      Parent shall have the foregoing right to terminate if, at the time of such termination, the Company or ioneer Parent is in material breach of any of its representations, warranties or covenants contained herein such as would result in any of the
      closing conditions set forth in Section 2.3 not being satisfied; and

    

    

    (g)       by either Party, pursuant to Section 8.3(c).

    

    

    Section 7.2        Notice of Termination; Effect of Termination.

    

    

    (a)       A terminating Party shall provide notice of termination to the other Party specifying with particularity the reason for such termination, and any such termination in accordance with Section

        7.1 shall be effective immediately upon delivery of such written notice to the other Parties.

    

    

    (b)      In the event of termination of this Agreement by any Party as provided in Section 7.1, this Agreement shall forthwith become void and there shall be no liability or obligation on the
      part of any Party except with respect to this Section 7.2 and Article VIII (and any defined terms in Section 1.1 implicated in the foregoing Sections) which shall remain in full force and effect; provided, however, that, notwithstanding anything to the contrary herein, no such termination shall relieve any Party from liability for any Damages resulting from or arising out of a
      Willful Breach of this Agreement.

    

    

    (c)      In the event that (i) this Agreement is terminated by the Company or ioneer Parent pursuant to Section 7.1(a) as a result of the condition set forth in Section 2.2(b) (Phase
      1 Required Permits) not being satisfied by the Longstop Date (as extended pursuant to Section 7.1(a), if applicable) and (ii) within *** of the date of termination, the Phase 1 Required Permits are obtained and ioneer Parent or any of
      its Affiliates enters into a binding agreement with a third party for the equity financing of all or part of the Project and the transactions contemplated by such binding agreement are thereafter consummated, then (x) ioneer Parent shall notify SSW
      Parent immediately of the consummation of such equity financing transaction and (y) within *** Business Days after the consummation of such equity financing transaction, ioneer Parent shall pay SSW Parent a lump-sum amount in cash equal to *** via

      52

      
        


    

    (d)      Notwithstanding anything in this Agreement to the contrary, and for the avoidance of doubt, the termination of this Agreement shall not, in any way, alter or limit any of the obligations of
      the Parties or any of their respective Representatives (as defined in the Confidentiality Agreement) or any of the rights of the Company and its Affiliates, in each case, under the Confidentiality Agreement, which obligations and rights shall survive
      the termination of this Agreement in accordance with its terms.

    

    

    (e)     Expenses and Other Payments.  Except as otherwise provided in this Agreement, each Party shall pay its own expenses incident to preparing for, entering into and carrying out this

    ARTICLE VIII

    MISCELLANEOUS

    

    

    Section 8.1        Notices.

    

    

    (a)      All notices, requests or consents provided for or required to be given under this Agreement shall be in writing and shall be deemed to be duly given if personally delivered, or mailed by
      certified mail, return receipt requested, or nationally recognized overnight delivery service with proof of receipt maintained, or given by email, in each case, pursuant to the address and contact information set forth on Exhibit C.  All
      notices given in accordance with this Agreement shall be effective upon delivery at the address of the addressee.  Either Party may change its contact information for notice by giving written notice to the other Party in the manner provided in this Section

        8.1.

    

    

    (b)      Whenever any notice is required to be given by Law or this Agreement, a written waiver thereof, signed by the Person entitled to notice, whether before or after the time stated therein,
      shall be deemed equivalent to the giving of such notice.

    

    

    Section 8.2     Payments.  All payments of the Total Consideration shall be made by wire transfer
      of immediately available funds to an account or accounts designated by the Company in writing to Investor, such designation to be provided not later than *** Business Days prior to the Closing Date.

    

    

    
      53

      
        


    

    Section 8.3       Disclosure Schedule.

    

    

    (a)      For the purposes of this Agreement, any information or matter disclosed in the Disclosure Schedule with respect to any Section of this Agreement shall be deemed to have been disclosed with
      respect to any other Section to the extent the applicability thereto is readily apparent on the face of such disclosure.  No reference to or disclosure of any item or other matter in the Disclosure Schedule shall be construed as an admission or
      indication that such item or other matter is material (nor shall it establish a standard of materiality for any purpose whatsoever) or that such item or other matter is required to be referred to or disclosed in the Disclosure Schedule.  The
      information set forth in the Disclosure Schedule is disclosed solely for the purposes of this Agreement, and no information set forth therein shall be deemed to be an admission by any Party hereto to any third party of any matter whatsoever,
      including any violation of Law or breach of any contract.  The Disclosure Schedule and the information and disclosures contained therein are intended only to qualify and limit the representations, warranties and covenants of the Company contained in
      this Agreement.  Nothing in the Disclosure Schedule shall be deemed to broaden the scope of any representation or warranty contained in this Agreement or create any covenant.  Matters reflected in the Disclosure Schedule are not necessarily limited
      to matters required by this Agreement to be reflected in the Disclosure Schedule.  Such additional matters are set forth for informational purposes and do not necessarily include other matters of a similar nature.

    

    

    (b)       From time to time prior to the Closing Date, the Company may supplement or amend the Disclosure Schedule (including, in each case, by the Company adding Disclosure Schedules that are
      responsive to the representations and warranties in question) with respect to any event, development, occurrence or non-occurrence of an event arising after the Execution Date (each a “Schedule
        Supplement”) if such event, development, occurrence or non-occurrence of an event would cause any representation or warranty made by the Company in Article III to be untrue or inaccurate as of the Closing Date.  Notwithstanding the
      foregoing, (i) for all purposes, including for purposes of determining whether the conditions to the Closing set forth in Article II have been fulfilled, the Disclosure Schedule shall be deemed to include only the information contained
      therein on the Execution Date, (ii) the delivery of a Schedule Supplement shall not affect ioneer Parent’s indemnification obligation pursuant to Article VI in any manner whatsoever, i.e., ioneer Parent’s indemnification obligation pursuant to
      Article VI shall be determined as if no such Schedule Supplement has been delivered, (iii) to the extent that the Company determines that any such event, development, occurrence or non-occurrence that is the subject of a Schedule Supplement
      constitutes or relates to something that (either individually or in the aggregate with all or any other predecessor Schedule Supplements) would prevent the conditions to the Closing set forth in Section 2.2 and Section 2.3 from being
      satisfied or otherwise permit Investor to terminate this Agreement pursuant to Section 7.1, then the Company will advise Investor in writing of such determination at the time that such Schedule Supplement is delivered to Investor (any
      Schedule Supplement in which the Company provides Investor written notice of such determination, a “Material Supplement”), but the delivery of a Material Supplement shall not affect ioneer
      Parent’s indemnification obligation pursuant to Article VI in any manner whatsoever, i.e., ioneer Parent’s indemnification obligation pursuant to Article VI shall be determined as if no such Material Supplement has been delivered even if Investor has
      elected not to exercise the right to terminate this Agreement pursuant to Section 7.1(e), and (iv) more generally and for the avoidance of doubt, Investor shall be deemed not to have waived any rights to indemnification pursuant to Article

        VI with respect to any event, development or occurrence described on any Schedule Supplement or Material Supplement.

     

    

    
      54

      
        


    

    (c)       The Parties shall each use their commercially reasonable efforts to meet in good faith from time to time until the date that is *** days after the Execution Date (the “Required Permit Schedule Amendment Date”) to discuss the completeness of the list of the Phase 1 Required Permits set forth on Part 1 of Schedule 1.1-RP as the Permits necessary to
      commence the construction of Phase 1 of the Project in accordance with the Consolidated Project Budget and Feasibility Study. Notwithstanding anything in Section 8.3(b) to the contrary, any amendments to Part 1 of Schedule 1.1-RP
      agreed to by the Parties by the Required Permit Schedule Amendment Date shall be deemed to amend Part 1 of Schedule 1.1-RP effective as of the Execution Date for all purposes under this Agreement, including for purposes of determining whether
      the conditions to the Closing set forth in Article II have been fulfilled and for purposes of determining whether a breach of any of the representations and warranties of ioneer Parent and the Company set forth in Article IV has
      occurred. In the event that Investor proposes in writing to the Company in good faith that Part 1 of Schedule 1.1-RP be amended to include an additional Permit (other than de minimis Permits and
      non-discretionary Permits) by the date that is *** Business Days prior to the Required Permit Schedule Amendment Date and the Parties are thereafter unable to agree on whether to include such Permit in an amended Part 1 of Schedule 1.1-RP by
      the Required Permit Schedule Amendment Date, then either Party shall have the right to terminate this Agreement without further liability to the other Party by providing notice of such termination to the other Party no later than *** after the
      Required Permit Schedule Amendment Date.

    

    

    Section 8.4     Entire Agreement. This Agreement (including the Annexes, Exhibits and Schedules to this Agreement), together with the other Transaction Documents, and any other writings delivered pursuant to this Agreement, constitutes the entire agreement
        among the Parties with respect to the subject matter hereof and thereof and supersedes all prior contracts, agreements and understandings, whether oral or written, among the Parties with respect to the subject matter of this Agreement.

    

    

    Section 8.5       Binding Effect; Assignment; No Third Party Benefit.  This Agreement shall be binding upon and shall inure to the benefit of the Parties and their respective heirs, permitted successors, and permitted assigns, and by their signatures hereto,
        each of the Parties intends to and does hereby become bound.  Except to the extent expressly provided in this Agreement (including the rights of the Investor Group pursuant to Section 6.2(a) and of the Company Group pursuant to Section
          6.2(b)), nothing in this Agreement is intended or shall be construed to give any Person other than the Parties and their respective heirs, permitted successors, and permitted assigns any legal or equitable right, remedy or claim under, in or
        in respect of this Agreement or any provision of this Agreement; provided that only a Party and its successors and permitted assigns will have the right to enforce the provisions of this Agreement on its
        own behalf or on behalf of any of its related Investor Group or Company Group, as applicable (but shall not be obligated to do so).  Neither this Agreement nor any of the rights, interests, or obligations hereunder shall be assigned by any Person
        without the prior written consent of the other Parties; provided that the Company may, upon written notice to the other Parties, assign its rights, interests or obligations under this Agreement, in whole or
        in part, to the Company’s or its Affiliates’ debt financing sources for collateral security purposes; provided, however, that any such assignment shall not relieve
        any Party of any of its obligations hereunder.

    

    

    
      55

      
        


    

    Section 8.6     Severability.  If any provision of this Agreement is held to be illegal, invalid or unenforceable under present or future Laws effective during the term of this Agreement, such provision shall be fully severable; this Agreement shall be
        construed and enforced as if such illegal, invalid or unenforceable provision had never comprised a part of this Agreement; and the remaining provisions of this Agreement shall remain in full force and effect and shall not be affected by the
        illegal, invalid or unenforceable provision or by its severance from this Agreement; provided, however, that if any such provision may be made enforceable by
        limitation thereof, then such provision shall be deemed to be so limited and shall be enforceable to the maximum extent permitted by applicable Law.  Furthermore, in lieu of (and to the extent of) each such illegal, invalid or unenforceable
        provision, there shall be added automatically as a part of this Agreement a provision as similar in terms to such illegal, invalid or unenforceable provision as may be possible and be legal, valid and enforceable.

    

    

    Section 8.7      Governing Law. This Agreement shall be governed by and construed in accordance with the Laws of the State of Delaware without giving effect to any of the conflict of laws rules thereof.

    

    

    Section 8.8     Consent to Jurisdiction; Waiver of Jury Trial.  Any action or proceeding relating to this Agreement shall be brought and enforced exclusively in the Delaware Court of Chancery or, solely if such court does not have jurisdiction, then in
        the state or federal courts in the State of Delaware, and the Parties irrevocably submit to the jurisdiction of such courts in respect of any such action or proceeding, and appropriate appellate courts therefrom, over any dispute arising out of or
        relating to this Agreement or any of the transactions contemplated hereby, and each party hereby irrevocably agrees that all claims in respect of such dispute may be heard and determined in such courts. The Parties hereby irrevocably waive, to the
        fullest extent permitted by applicable Law, any objection which they may now or hereafter have to the laying of venue of any dispute arising out of or relating to this Agreement or any of the transactions contemplated hereby brought in such courts
        or any defense of inconvenient forum for the maintenance of such dispute. Each of the Parties agrees that a judgment in any such dispute may be enforced in other jurisdictions by suit on the judgment or in any other manner provided by Law. This
        consent to jurisdiction is being given solely for purposes of this Agreement and is not intended to, and shall not, confer consent to jurisdiction with respect to any other dispute in which a party to this Agreement may become involved. Each of the
        Parties hereby consents to process being served by any party to this Agreement in any suit, action, proceeding or counterclaim of the nature specified in this Section 8.8 by the mailing of a copy thereof in the manner specified by the
        provisions of Section 8.1.   AS A SPECIFICALLY BARGAINED INDUCEMENT FOR EACH OF THE PARTIES TO ENTER INTO THIS AGREEMENT (EACH PARTY HAVING HAD THE OPPORTUNITY TO CONSULT COUNSEL), EACH PARTY ACKNOWLEDGES AND AGREES THAT ANY CONTROVERSY
        WHICH MAY ARISE UNDER THIS AGREEMENT IS LIKELY TO INVOLVE COMPLICATED AND DIFFICULT ISSUES, AND THEREFORE EACH OF THE PARTIES TO THIS AGREEMENT KNOWINGLY, VOLUNTARILY AND IRREVOCABLY WAIVES ALL RIGHT TO TRIAL BY JURY IN ANY LEGAL PROCEEDING ARISING
        OUT OF OR RELATING TO THIS AGREEMENT OR ANY OF THE TRANSACTIONS CONTEMPLATED BY THIS AGREEMENT.

    Section 8.9      Injunctive Relief.  The Parties acknowledge and agree that irreparable damage would occur in the event any of the provisions of this Agreement are not performed in accordance with their specific terms or are otherwise breached and that
        monetary damages alone would not be a sufficient remedy.  It is accordingly agreed that the Parties shall be entitled to a temporary, preliminary, or permanent injunction or injunctions to prevent breaches of the provisions of this Agreement,
        without posting a bond or any other undertaking, and shall be entitled to enforce specifically the provisions of this Agreement, in any court of the United States or any state thereof having jurisdiction, in addition to any other remedy to which
        the Parties may be entitled under this Agreement, at Law or in equity.

    

    

    Section 8.10     Amendment or Restatement.  This Agreement (including any Exhibit and Schedule hereto (other than Exhibit C, which may be amended in accordance with Section 8.1(a))) may only be amended, modified, supplemented or restated
        by an instrument in writing executed by all Parties and expressly identified as an amendment, restatement, supplement or modification.

    

    

    Section 8.11    Effect of Waiver or Consent.  Any of the terms, covenants, representations, warranties or conditions hereof may be waived only by a written instrument executed by or on behalf of the Party waiving compliance.  A waiver or consent, express or
        implied, to or of any breach or default by any Person in the performance by that Person of its obligations with respect to this Agreement is not a consent or waiver to or of any other breach or default in the performance by that Person of the same
        or any other obligations of that Person with respect to this Agreement.  Failure on the part of a Person to complain of any act of any Person or to declare any Person in default with respect to this Agreement, irrespective of how long that failure
        continues, does not constitute a waiver by that Person of its rights with respect to that default until the applicable statute of limitations period has run.  Except where otherwise provided herein, the rights of the Parties under this Agreement
        shall be cumulative, and the exercise or partial exercise of any such right shall not preclude the exercise of any other right.

    

    

    Section 8.12   Negotiation of Agreement.  The Parties have participated jointly in the negotiation and drafting of this Agreement.  In the event an ambiguity or question of intent or interpretation arises, this Agreement shall be construed as if drafted
        jointly by the Parties and no presumption or burden of proof shall arise favoring or disfavoring any Party by virtue of the authorship of any of the provisions of this Agreement.

    

    

    Section 8.13    Counterparts.  This Agreement may be executed in one or more counterparts, each of which when executed shall be deemed to be an original but all of which shall constitute one and the same agreement.  Delivery of an executed signature page of
        this Agreement by facsimile or other customary means of electronic transmission (e.g., “pdf” or signature via DocuSign or similar services) shall be effective as delivery of a manually executed counterpart hereof.
