incorporated by agreement between the Parties and that the incorporation of those provisions does not derogate from, or otherwise limit, the operation of Section 19 of this Agreement and that the governing law of this Agreement remains at all
times as provided in Section 19. Sub-licensor makes no representation as to whether such provisions will be available to Sub-licensee in the event of the bankruptcy of Sub-licensor. 
  

 ***CONFIDENTIAL MATERIAL REDACTED AND SEPARATELY FILED WITH THE COMMISSION*** 








 2.6 Conditions to Maintenance of the Non-Exclusive Sublicense and License Granted to Sub-licensee.
Sub-licensor will have the right to terminate the Sublicense and the License if Sub-licensee does not meet the following performance milestones: 
 (i) Within *** of the Execution Date, Sub-licensee (and/or any of its Affiliates and/or the Project Entities) shall have collectively achieved Commercial Start Up of at least *** of aggregate Installed Capacity utilizing KCT and/or the ***
in one or more of the Approved Applications. 
 (ii) Within *** of the Execution Date, Sub-licensee (and/or any of its Affiliates and/or the
Project Entities) shall have collectively achieved Commercial Start Up of at least *** of aggregate Installed Capacity utilizing KCT and/or the *** in one or more of the Approved Applications. 
 (iii) Within *** of the Execution Date, Sub-licensee (and/or any of its Affiliates and/or the Project Entities) shall have collectively achieved

 Failure by Sub-licensee (and/or any of its Affiliates and/or the Project Entities) to meet the foregoing performance criteria for the maintenance of the Sublicense and the License shall result, upon written notice from Sub-licensor, and the
failure to cure within 60 days of receipt of such notice, in the termination of the Sublicense and the License; provided however, Sub-licensor will not have the option to terminate the Sublicense or License for Sub-licensee’s failure to
meet the performance criteria, if Sub-licensee (or its designee) pays the royalties that would have been due to Sub-licensor if Sub-Licensee had met the performance criteria in this Section 2.6. 
 2.7 Acknowledgment of Sub-licensee Regarding *** Technology. Sub-licensee acknowledges that Sub-licensor has not yet been granted patent
protection for the *** technology, and that Licensor may take the position that such *** technology is a non-patentable modification of KCT that is covered by the terms of the existing License Agreement. Although Sub-licensor has no reason to
believe it will not be granted patent protection for the *** technology, any *** of Sub-licensor related to the *** will be *** if a ***. In the event that *** then: (i) *** and (ii) *** provided that ***. 
 3. Royalty Payments due Sub-licensor; Provision of Certain Engineering Services by Sub-licensor. 
 3.1(A) Royalties. Sub-licensee and/or qualified Project Entities shall make, during the term of this Agreement, royalty payments to
Sub-licensor equal to: 
  

	•	 	for all Approved Applications incorporating *** - *** of Installed Capacity (“*** Royalties”); and 

  

	•	 	for all Approved Applications incorporating KCT - *** of Installed Capacity (“KCT Royalties”). 

 The *** Royalties and the KCT Royalties will be collectively referred to as the “Royalties” 
 3.1(B) Royalty Exception. Notwithstanding Section 3.1(A) or Section 3.2, upon the expiration of the Licensed Patents
applicable to an Approved Application in a specific jurisdiction, Sub-licensor will no longer be obligated to pay the Royalties for future Projects utilizing KCT or *** 
  

 ***CONFIDENTIAL MATERIAL REDACTED AND SEPARATELY FILED WITH THE COMMISSION*** 








 (as the case may be) in such Approved Application. For example, upon the expiration of the KCT patents in the United
States, Sub-licensee will not longer be obligated to pay the Royalties for the utilization of KCT in Projects located in the United States. 
 3.2 Timing of Royalty Payments; Certain Assurances of Sub-licensor

shall be payable in two installments: (a) the first installment of *** (based on the expected Installed Capacity) will be paid upon the earlier of: (i) at the beginning of physical construction of a Project that will utilize the *** or KCT
in an Approved Application or (ii) within *** of the time when an Approved Application qualifies as a Project under this Agreement, and (b) the second installment of *** will be paid within *** after Commercial Start Up of such Project.
The second installment will be adjusted, as may be required, to reflect actual Installed Capacity (as compared to expected Installed Capacity) at the time of Commercial Start Up. This second installment will reflect actual Installed Capacity and
will act as a true-up taking into account the amounts paid in the first installment. 
 3.2(B) Sub-licensee or a Project Entity shall have
the right to pay directly to Exergy that portion of the Standard Royalty Payments due Exergy by Sub-licensor under the License Agreement for Approved Applications utilizing KCT (i.e. *** of Installed Capacity) upon written notice to Sub-licensor. In
such case, Sub-licensee shall obtain written acknowledgment from Exergy of receipt of payment, and shall indemnify Sub-licensor against any subsequent claims by Exergy that such royalties were not received by Exergy. 
 3.2(C) Should *** under the License Agreement that a *** and that *** under such ***, Sub-licensor will pay such *** in order to avoid any *** under the
License Agreement arising from such ***. 
 3.3 Engineering Services to be Provided by Sub-licensor to Sub-licensee. To facilitate
Sub-licensee’s efforts to construct any Project incorporating the Approved Applications, Sub-licensor agrees to provide upon request, at the *** rates of Sub-licensor as set forth in Exhibit C, the engineering services of Sub-licensor
including, but not necessarily limited to, KCT and *** technology process engineering, purchase specifications for plant and equipment, vendor recommendations, and advice on improvements or enhancements. 
 3.4 Provisions Governing the Supply of Engineering Services to Sub-licensee.  
 Engineering services will be provided by employees of Sub-licensor who have expertise in the use and application of KCT and *** in the applicable type of

 Subject to Sub-licensor’s covenant in Section 4.2(vii), Sub-licensee acknowledges that the provision of such
engineering services is subject to the demand of such services by other customers of Sub-licensor to which Sub-licensor has previously committed to perform similar engineering services and that such other customers to which Sub-licensor is
previously committed will have priority over Sub-licensee in access to such engineering services. Subject to Sub-licensor’s covenant in Section 4.2(vii), Sub-licensor reserves the right to control its own work schedule and priorities with
regard to work that is performed. 
 3.5 Access to Licensed Technical Information. Sub-licensee shall have 90 days from the Execution
Date of this Agreement to review the Licensed Technical Information in the possession of Sub-licensor, and to make copies thereof. Sub-licensee shall pay Sub-licensor for its time and expenses in assisting with this review at the *** rates of
Sub-licensor as set forth in Exhibit C. Following this period, Sub-licensor shall have no further ongoing obligation to make Licensed Technical Information available to Sub-licensee, other than such information that may be incorporated in
engineering services provided to Sub-licensee under Section 3.4. 
 4. Term and Termination; Representations and Covenants
of Sub-licensor. 
 4.1 Term; Preservation of License Granted by Licensor. Except as otherwise provided in this Agreement, the
term of the Sublicense shall be coterminous with the term of the License Agreement. The term of the License will extend through the term of the last to expire of the *** patents (if any) in each country, or if such *** patent applications are not
granted, through the date of such rejection. The term of this Agreement will start on the Execution Date and will expire upon the termination of the Sublicense and License as set forth in this Section 4.1. Notwithstanding the foregoing, or any
other provision of this Agreement, should Raser, or any of the Raser Releasors (as such term is defined in the Mutual Release) challenge on any grounds whatsoever, in written or oral form as verified by an independent third party, the releases
contained in Sections 1, and 3-5 of the Mutual Release, the Sublicense and License may be terminated by Sub-licensor without liability to Sub-licensee or any Project Entity, except with respect to those Projects for which royalties have already been
paid by Sub-licensee or such Project Entity hereunder. Any such termination will not affect the separate sublicenses, if any, that have been previously granted to other entities by Sub-licensor pursuant to the provisions of Section 2.3(i). The
confidentiality and non-circumvention provisions contained in this Agreement shall survive any such termination. 
 If the Sub-licensor
becomes the legal and beneficial owner of all of the KCT Licensed Patents then: 
 (i) this Agreement and the Sublicense granted hereunder
will remain in full force and effect and will not be subject to the License Agreement; 
 (ii) this Agreement will become a head/primary
license (i.e. not a sublicense) between Sub-licensor and Sub-licensee in respect of the KCT Licensed Patents and this Agreement will be read and interpreted accordingly;

of such other party hereto, whether of a similar or dissimilar nature thereto and shall not be deemed a continuing waiver of any breach or failure hereunder. All waivers of any term or condition of this Agreement must be in writing, signed by an
authorized representative of each party. 
 4.5 Survival of Rights. Expiration or termination of this Agreement or the Sublicense
granted hereunder shall not release either Party hereto from any liability related to this Agreement which as of the date of expiration or termination has already accrued, nor affect in any way the survival of any right, duty, or obligation of
either Party hereto which is expressly stated elsewhere in this Agreement to survive expiration or termination hereof. 
 4.6
Confidentiality Provisions. The Parties agree with each other to keep confidential, and not disclose to third parties, other than Affiliates, Project Entities and bona fide advisors, contractors, and financiers, the terms of this Agreement or
information regarding KCT or *** technology and their application to Power Plants and all other applications which was not already rightfully known to such Party without restriction before the commencement of negotiations with respect to this
Agreement or which was otherwise not in the public domain, (“Confidential Information”). Each Party shall be responsible for breaches of confidentiality obligations under this Agreement by its sub-licensees (including in the case of
Sub-licensee, a breach by a Project Entity), its employees and independent contractors. Notwithstanding the foregoing, either Party (the “Disclosing Party”) may disclose Confidential Information if: (i) in the reasonable opinion of
its counsel, such disclosure is required by law, the rules of any stock exchange or government or public authority having jurisdiction over the Disclosing Party, provided that the Disclosing Party (A) gives adequate prior notice of such
disclosure to the other Party, and (B) seeks, and uses its commercially reasonable efforts to obtain, confidential treatment of, or a protective order with respect to, those portions of the Confidential Information that such other Party, in its
sole discretion, requests the Disclosing Party to seek confidential treatment of, or a protective order with respect to or (ii) the other Party consents to both the form and the substance of each such disclosure. 
  

 ***CONFIDENTIAL MATERIAL REDACTED AND SEPARATELY FILED WITH THE COMMISSION*** 








 Either Party claiming an exemption from confidential treatment of Confidential Information regarding KCT
or *** technologies on the grounds the information was known to the Party before the date of this Agreement or was already in the public domain shall have the burden of establishing, by a preponderance of the evidence, that such information was
already rightfully known to such Party without restriction prior to the commencement of negotiations for this Agreement, or was in the public domain without breach of this Agreement prior to such date. The Parties acknowledge to each other that a
breach of the foregoing covenant will cause irreparable harm to the owner of such Confidential Information, and hereby waive any objections to specific performance of the foregoing covenant. Sub-licensee may not claim an exemption from confidential
treatment for information obtained by it in connection with its due diligence for the merger transaction with Amp Resources or for information obtained from individuals who have been employed by either Sub-licensor or Sub-licensee or their
affiliates. 
 Upon the termination or expiration of this Agreement, the Parties agree to return to each other all Confidential Information
provided to the Party, including all copies thereof, and take reasonable steps to ensure that their respective bona fide advisors, contractors and financiers do the same; provided however if portions of such Confidential Information are
needed in order to effectively utilize and receive the benefit of the License Patents, Sub-licensee, it Affiliates or the applicable Project Entities may keep and use such portions of the Confidential Information provided that such use is in
accordance with this Section 4.6. 
 In addition, Sub-licensee also agrees that, until Sub-licensor obtains patent protection for the
*** technology in the United States and all countries in which *** currently has a pending patent, Sub-licensee shall not disclose any material, non-public information regarding the *** to third parties unless such third parties: (i) are
Project Entities or are otherwise involved in the construction, operation of a Project incorporating *** technology, (ii) have a “need-to-know” such information to perform their duties, and (iii) then only after such persons have
executed a confidentiality and non-circumvention agreement that is adequate to protect Sub-licensor patent rights. The foregoing covenants and obligations shall survive the termination or expiration of this Agreement. 
 Consistent with this Section 4.6, Sub-licensee agrees to protect all engineering documents provided by Sub-licensor from disclosure and agrees that
Sub-licensor shall retain ownership of all information contained in such engineering documents. 
 5. Notices. Any notice authorized or
required to either Party hereto shall be in writing and in English and may be given by confirmed facsimile transmission to such Party, by recognized overnight courier, by hand delivery, or by U.S. Mail (postage pre-paid, return receipt requested),

 6. Further Actions and Cooperation. The Parties hereby agree to execute and deliver such additional documents and to
take such further actions as may become reasonably necessary or desirable to fully carry out the provisions and intent of this Agreement and to facilitate the financing of Projects by Sub-licensee or the Project Entities. In addition, the Parties
agree to cooperate in sharing high-level, general information relating to the implementation of *** and/or KCT in Approved Applications. 
  

 ***CONFIDENTIAL MATERIAL REDACTED AND SEPARATELY FILED WITH THE COMMISSION*** 








 7. Force Majeure. If a Party is unable, by reason of the occurrence of a force majeure event
to perform any obligation under this Agreement on time and as required, then that obligation shall be suspended, so far as the affected Party’s ability to perform it is affected by that force majeure event. If a force majeure event occurs, then
the Party whose performance is affected must as soon as practicable after the occurrence of that force majeure event, use its best endeavours including incurring any reasonable expenditure of funds and resources to mitigate the consequences of that
force majeure event and to minimize any resulting delay in the performance of its obligations under this Agreement. 
 If a Party becomes
aware of a circumstance which the Party reasonably considers, constitutes, or is likely to constitute or result in a force majeure event then the Party must as soon as practicable after becoming aware of the circumstance (but not more than
2 business days after) give the other Party notice of the circumstance and of the obligations under this Agreement which have been or will be or are likely to be effected by that circumstance and keep the other Party informed at reasonable
intervals and on the request of the other Party, of (i) the affected Party’s estimate of the likely duration of the force majeure event; and (ii) the mitigating action taken. 
 A force majeure event for purposes of this Agreement includes without limitation acts of God, acts of war (declared or undeclared), acts of public
enemies, riots, civil disturbance, riot, flood, fire, natural disaster, strikes, lockouts, other labor difficulties, disputes with employees (provided that those labor difficulties, or disputes with employees are beyond the reasonable control of a
Party), or other circumstance beyond the reasonable control of a Party. For the avoidance of doubt, a Party shall not be required to yield to the demands of its employees or independent contractors on the grounds that yielding to such demands is
within the reasonable control of a Party. 
 8. Authority. Each Party represents and warrants to the other Party that the person
signing for such Party has the right and authority to execute this Agreement in the capacity represented. Each Party represents to the other Party that the execution, delivery and performance of this Agreement have been duly authorized by all
required corporate or company action, and that there are no third party consents required for the execution of this Agreement by such Party. 
 9.
Assignment. Except as otherwise expressly provided herein, neither Party shall assign, transfer, encumber or otherwise dispose of in any way its rights, interest or duties hereunder, in whole or in part, either voluntarily
or by operation of law without the express prior written consent of the other Party, provided that either Party may, without the express prior written consent of the other Party, assign, transfer or otherwise dispose of its rights, interest or
duties hereunder, in whole or in part, to a successor to all, or substantially all, of the assets or business of such Party, whether by merger, sale of stock, sale or assets or other similar transaction; provided that the assuming party agrees in
writing that it will assume all the obligations of the assigning Party. Any such attempted disposition in violation of the foregoing terms shall be invalid ab initio as between the Parties. Sub-licensee shall be allowed to assign this
agreement to an Affiliate subject to Guarantor remaining liable for all obligations, covenants, representations, and warranties of such Affiliate under this Agreement. 
 10. Successors and Assigns. This Agreement shall become effective upon the date of execution of this Agreement and the Mutual Release by Raser and PAC, and shall continue in full force and
effect until such time as all obligations of the Parties are fully discharged hereunder, or this Agreement is terminated pursuant to the provisions contained herein. This Agreement shall be binding upon, and inure to the benefit of, the heirs,
successors and permitted assigns of the Parties. 
  

 ***CONFIDENTIAL MATERIAL REDACTED AND SEPARATELY FILED WITH THE COMMISSION*** 








 11. Entire Agreement. This Agreement contains the entire understanding of the Parties with
respect to the subject matter hereof. There are no oral understandings, statements or stipulations bearing upon this Agreement that have not been incorporated herein. This Agreement supersedes all prior negotiations and understandings of any kind
with respect to the subject matter hereof. 
 12. Amendments. No course of dealing or conduct shall be effective to amend, modify,
change, release or waive any provision of this Agreement. This Agreement may not be altered, amended, modified or waived except by a writing executed by duly authorized representatives of both Parties. 
 13. No Third Party Rights—No Partnership. This Agreement shall not be deemed to give any right or remedy to any third party whatsoever
unless that right or remedy is specifically granted by the Parties hereto in writing to such third party and nothing contained herein shall be construed in any manner to create any relationship between the Parties other than the contract
relationship created hereby and the Parties shall not be considered partners or co-venturers for any purpose. 
 14. Remedies
Cumulative. Except as otherwise expressly provided herein, no remedy conferred upon or reserved by any Party herein is intended to be exclusive of any other available remedy or remedies, but each and every such remedy shall be
cumulative and shall be in addition to every other remedy given under this Agreement or available at law or in equity. 
 15. Construction
Principles. Words in the masculine gender in this Agreement shall be deemed to include the feminine and neuter genders and vice versa and whenever the singular number is used and when required by the context, the same shall include
plural. The paragraph headings are solely for guidance convenience and shall have no significance in the interpretation of this Agreement. 
 16.
Counterparts. This Agreement may be executed in any number of counterparts, each of which shall be deemed an original and as executed shall constitute one agreement, binding on both Parties even though both Parties do not
sign the same counterpart. A facsimile copy of a signature of this Agreement shall constitute an original signature for the purposes of this Agreement. 
 17. Legal Counsel. Each Party hereto acknowledges that it has read this Agreement in its entirety and acknowledges that it has legal counsel who has reviewed this Agreement and participated in the drafting hereof
and has advised it concerning the content and legal effect hereof. 
 18. Severance Clause. Any finding of invalidity,
unenforceability or illegality of any part of this Agreement for any reason shall not invalidate or affect the remainder, which shall continue to govern the relative rights and duties of the Parties as though the invalid, unenforceable or illegal
part were not a part hereof. 
 19. Interpretation, Enforcement, Attorney Fees. This Agreement shall be construed in accordance
with, and governed by, the laws of the State of Utah. 
 In the event of any irresolvable dispute, the Parties agree to first submit the
disputed issue to non-binding mediation in Utah, with each Party bearing its own costs and attorney fees. 
 If mediation fails, then the
Parties agree that either Party may submit the dispute to binding arbitration pursuant to the Commercial Rules of the American Arbitration Association, with all arbitration proceedings to be held in Salt Lake City, Utah and with the governing law of
the 
  

 ***CONFIDENTIAL MATERIAL REDACTED AND SEPARATELY FILED WITH THE COMMISSION*** 








 proceedings being the laws of Utah. The Parties agree that (i) the award of the arbitration panel shall be binding
(ii) may be enforced in any court of competent jurisdiction, (iii) in any such enforcement proceeding, the Parties hereby consent to, and submit to the personal jurisdiction of, such courts, and agree to accept service of process in any
such proceedings by certified mail, return receipt requested, addressed to the address at which such Party receives notices under Section 5 of this Agreement. Finally, the Parties agree that the prevailing Party shall be entitled to reasonable
attorney fees, costs and expenses.
