(e)Notwithstanding the provisions of this Section 5.07, the restrictions of this Section 5.07 will not apply if an unrelated Third Party makes an unsolicited written proposal to Westwater to acquire Westwater, the Acquired Companies or the assets of the Acquired Companies which (a) in the good faith opinion of the board of directors of Westwater, would if completed in accordance with its terms result in a transaction more favorable from a financial point of view to the shareholders of Westwater than the terms of the transactions contemplated hereby and (b) if the board of directors of Westwater reasonably believes, after consultation with its outside legal counsel, that failing to respond to and take any relevant action in respect of such proposal would be inconsistent with the performance by the directors of their fiduciary duties under applicable law (a "Superior Proposal"). If Westwater receives a Superior Proposal, Westwater will provide written notice to Purchaser that it intends to proceed with the Superior Proposal, together with a copy of the Superior Proposal and a certificate of an officer of Westwater certifying that such Superior Proposal meets the requirements of this Section 5.07(e), together with supporting documentation as may reasonably be requested by Purchaser to establish compliance with this Section 5.07(e). Upon receipt of such notice of the Superior Proposal, Purchaser will have the right to match the terms of the Superior Proposal, which it may exercise by written notice of such exercise to Westwater within ten (10) Business Days after receipt of notice of the Superior Proposal in accordance with this Section 5.07(e). If Purchaser fails to exercise its rights to match the terms of the Superior Proposal, Westwater may proceed with the Superior Proposal following paying of the Break Fee to Purchaser.

Section 5.08Section 11e.(2) Material. Westwater estimates that there remains 3,340 cubic yards of uranium mining tailings or waste products as defined in Section 11e.(2) of the Atomic Energy Act of 1954, as amended 42 U.S.C Ch. 14 ("Section 11e.(2) Material") located at the Kingsville Dome Project, the Vasquez Project and the Rosita Project, subject to an additional twenty percent (20%) contingency, for a total of 4,000 cubic yards of Section 11e.(2) Material. In lieu of conducting any soil sampling and testing at such three (3) project sites, the Parties agree that if after Closing, Purchaser identifies and ships for disposal Section 11e.(2) Material in excess of 4,000 cubic yards, then Westwater will indemnify and reimburse Purchaser for any additional costs with respect to the excess Section 11e.(2) Material, up to a limit of One Hundred Twenty-Five Thousand Dollars ($125,000), which indemnification obligation will survive Closing for a period of up to sixty (60) months and is not subject to the limitations set forth in Section 9.04 or Section 9.05.

Section 5.09Sales of enCore Shares. For the period of twenty-four (24) months following the Closing Date, if Westwater intends to sell 250,000 or more of enCore Shares in a single sale, then Westwater must give at least three (3) Business Days prior written notice to enCore of such proposed sale, stating the price (which may reference market prices for enCore’s shares on the TSXV or an OTC market) and any other proposed terms of such sale. enCore will have the right to purchase all of such enCore Shares or to identify an alternate buyer to purchase all of such enCore Shares on the same terms, and in the case of proposed sales by Westwater at market prices on the TSXV or an OTC market, at the most recent closing price of enCore’s shares on the TSXV before delivery of the written notice by Westwater. enCore may exercise such right by written notice to Westwater within such three (3) Business Days period identifying the buyer, and a binding agreement relating to such purchase of the subject enCore Share must be

-26-

completed within a further three (3) Business Days (which will be deemed completed upon delivery of the purchase price to Westwater). If enCore elects not to purchase or identify a buyer for such subject enCore Shares and does not provide notice to Westwater within the three (3) Business Day period, or does not thereafter complete, or cause to be completed, a binding agreement relating to the purchase within the required further three (3) Business Days, then Westwater will be entitled to sell any of such enCore Shares on the same terms as proposed in the original notice of proposed sale. If the proposed sale of enCore Shares is not completed within a further three (3) Business Days or if there is a change in the price of other terms of the sale, excluding any changes in the market prices for enCore’s shares on the TSXV or an OTC market in the event Westwater provides notice of its intent to sell the enCore Shares on the TSXV or an OTC market, then the notice requirements and option provisions of this Section 5.09 will again apply to any intended sale of enCore Shares.

Section 5.10Post-Closing Consulting. After the Closing, Westwater will make available to Purchaser and the Acquired Companies the consulting services of Dain McCoig, Vice President of Operations, and Joshua Holland, Manager of Operations, for a period of up to twelve (12) months following Closing, for up to seven hundred fifty (750) hours each and at Closing enCore and Westwater will enter a consulting agreement to document such arrangement in a form substantially similar to that attached hereto as Exhibit 4.

Upon receipt of such application and directions, the Purchaser shall, and shall cause URI, Inc. to, (a) use commercially reasonable efforts to comply with Sections 1102 and 1106 of the CARES Act to obtain forgiveness of the PPP Loan, (b) file the provided application for forgiveness of the PPP Loan and take all other actions reasonably necessary to obtain forgiveness thereof, and (c) work in good faith with Westwater in the PPP Loan forgiveness process.

(a)any Taxes payable, including for greater certainty any amount required to be paid, withheld or remitted, by the Acquired Companies in respect of taxable periods (or portions of taxable periods) ending on or before the Closing Date;

Purchaser covenants and agrees to indemnify and hold harmless the Sellers and their shareholders, directors, officers, employees, agents, successors and assigns (the "Seller Indemnified Parties") from and against any Damages which any of the Seller Indemnified Parties may suffer or incur as a result of, or arising out of, or in respect of:

(b)any material inaccuracy in or material breach of any representation or warranty of the Purchaser contained in this Agreement;

(d)a Seller Indemnified Party having been, as the case may be, a shareholder, director, officer, employee, agent or guarantor of the obligations of the Acquired Companies.

Section 9.03Indemnification Actions. All claims for indemnification under this Article IX will be asserted and resolved as follows:

(a)Third Party Claims.

(i)Promptly after receipt by a Person entitled to indemnity under Section 9.01 or Section 9.02 (an "Indemnified Party") of notice of the assertion or commencement of an action, suit, claim or other legal proceeding made or brought against it by a Third Party (a "Third Party Claim"), such Indemnified Party will promptly give written notice to the Person obligated to indemnify against such

-35-

Third Party Claim (an "Indemnifying Party") of the assertion or commencement of such Third Party Claim; provided, that the failure to timely notify the Indemnifying Party will not relieve the Indemnifying Party of any Liability that it may have to any Indemnified Party, except to the extent of actual prejudice arising from such failure.

-36-

(iii)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, will 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, and (ii) each Party agrees (at its own expense) to render to each other such assistance as a Party may 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.

(iv)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 will, 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 will give the Indemnifying Party prompt written notice thereof; provided, however, the failure to give such prompt written notice will 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 will describe the Direct Claim in reasonable detail, will include copies of all material written evidence thereof and will indicate the estimated amount, if reasonably practicable, of Damages that have been or may be sustained by the Indemnified Party. In no event shall any Indemnifying Party be liable to any Indemnified Party in the case of a Direct Claim for any punitive, incidental, consequential, special or indirect damages, including loss of future revenue or income, loss of business reputation or opportunity relating to the breach or alleged breach of this Agreement, or diminution of value or any damages based on any type of multiple. The Indemnifying Party will have sixty (60) days after its receipt of such notice to respond in writing to such Direct Claim. During such sixty (60) day period, the Indemnified Party will 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 will 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

-37-

Indemnifying Party does not so respond within such 60-day period, the Indemnifying Party will be deemed to have rejected such claim, in which case the Indemnified Party will 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.

FORM OF ROYALTY DEED

ATTACHED TO AND MADE A PART OF THAT CERTAIN SECURITIES PURCHASE AGREEMENT DATED DECEMBER 31, 2020, BY AND AMONG ENCORE ENERGY CORP., WESTWATER RESOURCES INC., and URI NEUTRON HOLDINGS II, INC.

ROYALTY DEED

This ROYALTY DEED (“Royalty Deed”), effective as of December 31, 2020 (the “Effective Date”), is given by URANCO, INC., a corporation organized under the laws of Delaware (“Grantor”) whose address is 250 200 Burrard Street, Vancouver BC, V6C 3L6 to WESTWATER RESOURCES, INC., a Delaware corporation (“Grantee”), whose address is 6590 South Potomac Street, Suite 300, Centennial, Colorado 80112 (each a “party” and together “the parties”).

NOW, THEREFORE, for and in consideration of $10.00 and other good and valuable consideration, the receipt and sufficiency of which is hereby acknowledged, Grantor hereby GRANTS, ASSIGNS, CONVEYS, and WARRANTS unto Grantee, a royalty as herein defined, with respect to all Uranium mined or otherwise derived from properties identified in Exhibit A and Exhibit B to this Royalty Deed (the “Properties”), which is mined, produced, or otherwise prepared for sale.

1.NET SMELTER ROYALTY

Amount and Basis

1.1Pursuant to the terms of this Royalty Deed, Grantor shall pay Grantee a net smelter return royalty equal to two per cent (2%) of the net proceeds as defined herein received for Uranium mined, produced or otherwise derived from the Properties and processed or otherwise prepared for sale (the “Net Smelter Royalty” or “Net Smelter Royalties”).

Definitions

1.2“Uranium” means uranium in any natural or processed form, including yellowcake, and shall also include thorium and other fissionable or spatially associated metals, minerals or other valuable substances associated with or produced along with uranium.

1.3 “Spot U3O8 Price” means the average weekly spot price per pound of U3O8 for domestic delivery during the month in which such Uranium is sold, as quoted in the UX Weekly (published by The Uranium Exchange Company), or equivalent source if these sources are no longer available agreed upon by the parties. If the parties cannot reach agreement concerning the method to determine the Spot U3O8 Price within 30 days, then the parties will select an expert (the “Expert”) to make such a determination. If the parties cannot agree upon the selection of an Expert, an arbitrator shall be selected by application of the rules of the American Arbitration Association and the parties shall submit the issue to binding arbitration.

Exhibit 2-1

1.4“Net Proceeds” is defined as the total revenues generated from the sale of Uranium mined, produced, or otherwise derived from the Properties and processed, or otherwise prepared for sale from the Properties less only:

1.4.1the actual cost of transportation from the mine or mill or other concentrating facilities which includes commercially reasonable and customary packaging, freight, insurance, transportation taxes, handling, port, demurrage, delay and forwarding expenses incurred by reason of or in the course of such transportation to the point of sale,

1.4.2 the actual cost of any sample assays and analyses required and performed by agreement with a purchaser and occurring after Uranium is removed from a mill or other concentrating facilities,

1.4.3 any penalties for impurities, not to exceed normal accepted industry limits and standards for similar Uranium, and

1.4.4 severance, resource excise or other similar taxes and fees paid by Grantor and not based on Grantor’s income.

1.5 Any costs for processing or upgrading Uranium and any other costs not specifically mentioned in the definition of “Net Proceeds” above shall not be deducted from total revenues generated by sales of Uranium in calculating Net Proceeds and the Net Smelter Royalty.

Non-Arm’s Length Sales.

1.6To the extent Grantor sells Uranium in other than an “arms-length transaction”, gross proceeds shall be calculated based on a total “deemed sales price” equal to the Spot U3O8 Price. If such sales are of unmilled materials, the total deemed sales price shall be calculated on the basis of the anticipated recovery of the U3O8 contained in such material.

1.7An “arms-length transaction” means a bona fide transaction with a third-party purchaser, that is not an affiliate, subsidiary or parent of Grantor, or other entity in which Grantor has a material financial interest or exercises any degree of control.

Payment.

1.8The Net Smelter Royalties shall be due and payable in cash and shall be paid on or before the 20th day of the calendar month immediately succeeding the calendar month during which such royalties accrue and become payable. The Net Smelter Royalties shall be deemed accrued and payable within thirty (30) days of when Grantor receives payment in settlement for such Uranium sold or contracted. Each such royalty payment shall be accompanied by a written statement setting forth in detail the volumes of all Uranium attributable to such royalty payment and the basis for the calculation of the Net Smelter Royalties, including but not limited to date of sale and shipment, assay reports and purchaser’s settlement sheets, shipper and shipping weights, and invoices for any deductions pursuant to paragraph 1.4. If such Net Smelter Royalties or portions of such Net Smelter Royalties are derived from sales of unmilled materials, as described in paragraph 1.6, such written statement shall include the calculation of the anticipated recovery

Exhibit 2-2

of U3O8 contained in such unmilled materials. Grantee shall have the right at any time to request free copies of other records which Grantee may deem necessary to verify the accuracy of any or all royalty payments. Each statement furnished to Grantee shall be deemed to be correct and binding unless Grantee, within one year of its receipt, notifies Grantor that it disputes the correctness of such statement or requests an audit as defined in paragraph 1.9; provided, however, that the foregoing one-year limitation shall not apply in the case of fraud.

Right to Inspect and Audit.

1.9Upon not less than 48 hours advance notice, Grantor shall make available, and Grantee shall be entitled to inspect and copy, all records and data pertaining to the computation of the Net Smelter Royalty, including, without limitation, any such records and data that are maintained electronically. All such data shall be subject to the confidentiality restrictions of this Royalty Deed. Grantor shall at its own cost and expense cooperate with all reasonable audits requested and conducted by Grantee. The cost of any such audit shall be borne by Grantee, unless the results of such audit show an aggregate underpayment of the Net Smelter Royalty for the payments in question of greater than ten percent (10%), in which case Grantor shall reimburse Grantee for all reasonable and documented costs of the audit.

2.OPERATIONS

2.1The Grantor shall, during the term of this Royalty Deed, furnish Grantee, within 120 days of the completion of the Grantor’s fiscal year, a report with respect to work carried out by the Grantor on the Properties, the material results and segmented earnings thereof and plans or projections for the following year; provided that no report will be due for any year in which the Grantor has not undertaken operations on the Properties.

No Implied Obligations.

2.2There are no implied obligations arising under this Royalty Deed with respect to the exploration for and the development, mining, or marketing of Uranium from the Properties.

If Grantor’s proposal is made after March 1 of the year in which it is made, it shall do assessment work as to such claim or claims involved up to the date of such abandonment, surrender, or release.

2.3.D.If Grantor shall abandon title to one or more of the unpatented mining claims forming part of the Properties in accordance with this paragraph 2.3, Grantor shall have no further obligation whatsoever to Grantee with respect to such claims, except obligations existing at the time the claims were released.

Grantee shall have the right to have a representative present at the time samples are taken and shall be provided statements or reports of the results, provided, however, Grantee shall provide Grantor with not less than five days’ notice of Grantee’s intent to have such representative present at the time samples are taken and Grantee shall bear the entire cost of its representative. All statements or reports wherein Grantor's assay of samples are set forth shall be conclusively presumed to be true and correct unless, within ninety days after such statements or reports are delivered to Grantee, Grantee makes written objection thereto and demands an assay by an independent third party.

2.Calculation of Net Profits. Net Profits shall mean for any period, the profits from operations received during the period from the operation of the Projects as determined in accordance with generally accepted accounting principles (“GAAP”) consistently applied, except that Net Profits shall exclude any non-cash expense items such as depreciation, depletion or amortization, other than depreciation and amortization of capital expenditures.

3.Accounts; Reports. (a) , Neutron shall use accounting policies, procedures and conventions in accordance with GAAP for the calculation of Net Profits. Net Profits shall be computed, and the Net Profits Interest payment shall be distributed, quarterly for each fiscal quarter of Neutron as set forth herein.

(b)Within sixty days after the end of each fiscal quarter in which Neutron records Net Profits, including losses and costs and expenses from prior periods not previously recovered, Neutron shall pay Westwater an amount equal to Westwater’s Net Profits Interest.

(c)Within ninety days after the end of each fiscal year from time to time adopted by Neutron, Neutron shall deliver to Westwater a summary report certified by its chief accounting or financial officer or by a certified public accountant selected by Neutron showing : all cumulative costs and expenses related to the Projects; all cumulative revenues related to the Projects; all payments with respect to Westwater’s Net Profits Interest; all adjustments to such payments; and other matters.

(d)Each annual report shall be final and not subject to adjustment unless Westwater delivers to Neutron a written request for audit within six months after Neutron delivers the report to Westwater.

Exhibit 3-1

(e)Except in the case of fraud, gross negligence or wanton and willful misconduct, no miscalculation of amounts due or misinterpretation of this Agreement shall be the basis for a claim of breach of fiduciary duty, or the like, nor give rise to a claim for exemplary or punitive damages or for termination or rescission of this Agreement or termination of the estate and rights of Neutron in the Projects.

4.Nature of Westwater’s Interest. From and after the Effective Date, Westwater’s sole interest related to the Projects shall be the Net Profits Interest expressly provided in this Agreement. Westwater shall have no interest whatsoever in the Projects, whether in the nature of a royalty or profit, a remainder, reverter, right of re-entry or other future interest, or otherwise. Provided however, in the event Neutron in its sole discretion abandons, surrenders or fails to renew a lease on one or both of the Projects and subsequently enters into a new lease on one or both of the Projects within two years of the prior lease’s termination, Westwater’s Net Profits Interest will survive under the same terms and conditions as set forth herein.

5.Transferability. From and after the Effective Date, Neutron’s interest in the Projects shall be freely assignable or transferable and Westwater shall have no right of first refusal with respect to any sale, assignment or transfer related to the Projects.

7.Nature of Relationship. (a) This Agreement is not intended to create, and nothing contained herein shall be construed as creating, a partnership, a mining partnership, a commercial partnership, a tax partnership, a joint venture, joint enterprise, co-ownership of any kind of association or fiduciary relationship.

(b)Westwater and Neutron each shall be responsible only for its own obligations as set forth in this Agreement.

8.Exclusion of Implied Obligations. (a) Westwater covenants and agrees that Neutron shall have no obligation whatsoever, express or implied, to: (1) explore, develop or exploit the Projects, (2) make any expenditures in connection with the Projects, or (3) maintain in good standing the leases on the Projects for all of which Westwater relies solely on Neutron’s self-interest.

(b)Westwater also covenants and agrees that Neutron shall have sole discretion whether to continue, suspend, resume or terminate operations on the Projects, and sole discretion as to the manner and rate of any operations on the Projects, for all of which Westwater relies on Neutron’s self-interest.

(c)Without limiting the generality of the foregoing, Neutron may conduct such operations on or in connection with the Projects as it deems necessary, convenient or appropriate to recover and process uranium-bearing solutions from the Projects or to recover uranium by solution mining techniques. By way of example and not of limitation, such operations may include in-situ leaching, old stope leaching and mine water recovery. Neutron may construct or purchase ion-exchange facilities or other processing facilities for the recovery of uranium from solutions, or may arrange with another company, including affiliates, for processing of solutions for the recovery of uranium. Neutron shall have the exclusive right to market and sell all uranium ore mined and solutions recovered from the Projects, all uranium concentrates derived from such ores or solutions, and all other minerals recovered from the Projects. All decisions concerning the disposition of such ores, solutions or concentrates, including, by way of example but not of limitation, the buyer or buyers, time of sale, price, times of deliveries and terms of sale, shall be made by Neutron in its sole discretion.

(d)All ore mined from the Projects and solutions recovered from the Projects and the concentrates derived from the ores mined or solutions recovered from the Projects, as the case may be, may be commingled with similar products from other properties. Neutron shall estimate the quantity and quality of such ores mined or solutions and concentrates recovered therefrom, based upon techniques then employed and generally accepted in the mining industry and shall maintain records of such estimates until expiration of Westwater’s right of audit for the related year.

9.Inspection and Audit. (a) Upon reasonable notice to Neutron, Westwater shall have the right, at its risk and expense, to have a representative of Westwater reasonably acceptable to Neutron inspect operations conducted on the Projects by or for the benefit of Neutron for the purpose of determining compliance with this Agreement.

(b)Westwater shall have a period of six months after its receipt of each annual report to give Neutron notice of any objection by Westwater thereto. If Westwater fails to object to a particular statement within the six-month period, then the statement and the amount of any payment transmitted therewith will be final and conclusive as between the parties. This six-month limitation period shall not apply where underpayment results from fraud, gross negligence or wanton or willful misconduct.

Exhibit 3-3

(c)At any time, upon reasonable notice to the Neutron, Westwater requires a chartered or certified public accountant mutually acceptable to the parties and retained by Westwater to promptly audit Neutron’s relevant books and records related to the Projects.

(d)Any such audit will be made at the sole expense of Westwater if the audit determines that the Net Profits Interest payment in question was accurate within ten percent (10%). Any such audit will be made at the sole expense of Neutron if the audit determines that the payment in question was inaccurate by more than ten percent (10%).

(e)In any case, the payment in question will be adjusted to reflect the results of the audit and the appropriate payment or credit to the next Net Profits Interest payment made.

(f)Neutron shall have the right to condition access to the Projects and its books and records on execution by the auditor and the representative designated by Westwater of a written agreement that all information disclosed or made available to such persons shall be held in confidence and used solely for purpose of assuring compliance with the obligations of Neutron under this Agreement and resolution of any disputes related to this Agreement. Such a written agreement may also contain (1) an undertaking to comply with all health and safety laws, regulations and procedures from time to time in effect with respect to the Projects, (2) acknowledgments of the existence of hazards and risks arising out of operations on the Projects and (3) such other terms as are from time to time contained in releases and agreements required to be executed by other visitors to the Projects.

(g) If Westwater or any successor of Westwater ceases to own the entire Net Profits Interest, the audit, access and inspection rights of Westwater under this Agreement shall be exercisable from time to time only by one person authorized to exercise such rights by a writing executed by the persons then holding sixty percent or more of the ownership interest in the Net Profits Interest.

10.Amendment, etc. of Agreement. (a) No modification, waiver, amendment, discharge or change to or under this Agreement shall be valid unless the same is in writing and signed by the parties. Any waiver or consent given in any one instance shall not act as a waiver or consent for any other instance and shall be effective only on such terms and conditions as are specified in such waiver or consent.

(b)If Westwater or any successor of Westwater ceases to own the entire Net Profits Interest, then the rights, obligations and interests of Westwater and each and every one of the persons who is then a successor or assign of Westwater may be amended, varied or waived by a writing signed by the persons then owning sixty percent or more of the collective aggregate ownership interest in such Net Profits Interest and such a writing so signed shall bind Westwater and each and every such successor or assign of Westwater. “Successors or assigns of Westwater” as used in this Agreement shall include persons who acquire interests in the Net Profits Interest or in this Agreement.

11.Payments. (a) Any amounts payable by Neutron to Westwater under this Agreement shall be made by check or electronic funds transfer, as elected by Westwater, and sent to Westwater at the address first above written.

Exhibit 3-4

(b)If any third party asserts any claim to any amounts to be paid, credited or applied by Neutron to Westwater, Neutron may deposit such amounts in an interest-bearing escrow account until the dispute is finally resolved.

12.Governing Law. The existence, interpretation, performance and breach of this Agreement shall be governed solely by the law of the State of New Mexico.

13.Entire Agreement. This Agreement constitutes the entire agreement between Westwater and Neutron related to the Projects and the other matters referred to in this Agreement and supersede all prior discussions and negotiations. There are no conditions, covenants, agreements or understandings between Westwater and Neutron except those expressly contained herein.

14.Further Assurances. Westwater and Neutron agree one with the other to execute and secure the execution of all other documents and instruments as may be reasonably necessary or convenient to effectuate this Agreement, including, but not limited to, such consents and approvals as may be necessary or deemed desirable in the circumstances.

15.Limitations on Remedies. Westwater covenants and agrees that the exclusive remedy for one or more breaches by Neutron of this Agreement or of obligations arising under it shall be money damages. Westwater hereby expressly waives any right it might otherwise have to any remedy resulting in loss or diminution of Neutron’s right, title and interest in and to the Projects.

16.Assignment. Westwater’s and Neutron’s rights are freely assignable and transferrable subject to Neutron’s rights and obligations set forth in paragraph 5. Any party making an assignment or transfer shall provide the other party with 30 days written notice of such action prior to the assignment or transfer.

17.Dispute Resolution. If the parties are unable to resolve any disputes arising from this Agreement, they shall submit the dispute to arbitration in Albuquerque, New Mexico before a single arbitrator. The arbitrator shall be selected by mutual agreement of the parties. If the parties are unable to agree on an arbitrator, the arbitrator shall be selected by application of the rules of the American Arbitration Association.
