TERM AND TERMINATION. 

4.1 Term. The Term shall terminate upon the earlier to occur of (i) the last date upon which all U.S. Patents
terminate in fact without renewal, whether by expiration or invalidation, (ii) any valid termination of both (but not one) of the Equipment Leases, and (iii) such other date as provided herein. 

4.2 Other Termination. Any Party may terminate this Agreement prior to the end of the Term upon providing written notice to
the other Party if the other Party commits a material default or breach of any representation, warranty, covenant or agreement contained herein and fails to remedy any such default or breach within 30 days after receiving written notice describing
in reasonable detail the material default or breach from the non-defaulting or non-breaching Party. If Sublicensee so terminates this Agreement due to a breach by Sublicensor or Licensor, Sublicensor and Licensor, as applicable, shall reimburse
Sublicensee within 10 days of such termination the pro rata portion of the License Fee for the remainder of the year in which such termination occurs. Sublicensor and Licensor agree that monetary damages are an adequate remedy for any default or
breach of this Agreement by Sublicensee. 
 4.3 Effect of Termination of this Agreement or the License Agreement under
Certain Circumstances. The rights of Sublicensee set forth in Article II will survive any termination of this Agreement or the License Agreement or the dissolution of the Sublicensor; provided any such termination of this Agreement does
not occur as a result of a breach of this Agreement by Sublicensee (each of the foregoing, a “No-Fault Termination Event”). Licensor hereby grants to Sublicensee all of the rights and licenses granted to Sublicensee by Sublicensor
hereunder (including the Technology Sublicense). Sublicensee shall not exercise such rights and licenses unless and until a No-Fault Termination Event has occurred and the Technology Sublicense

  

 -6- 

 
granted hereunder has been terminated. Notwithstanding anything to the contrary in this Agreement or the License Agreement (including Section 5 thereof), upon the occurrence of a No-Fault
Termination Event resulting in the termination of the License Agreement, the termination of this Agreement or the dissolution of the Sublicensor (as applicable), Sublicensee may exercise the rights and licenses set forth in this Section 4.3 and
Licensor will assume all obligations of Sublicensor in this Agreement, both without any further action by any of the Parties. 

4.4 Effect of Bankruptcy of Sublicensor or Licensor. Sublicensor and Licensor acknowledge and agree that the Intellectual
Property rights licensed to Sublicensee hereunder constitute “intellectual property” as such term is defined in the Bankruptcy Code and that Sublicensee is entitled to all of the rights of a licensee of intellectual property under
Section 365(n) of the Bankruptcy Code with respect to all of such licensed rights, which rights under the Bankruptcy Code include, without limitation, the right, upon the rejection of this Agreement or the License Agreement in any case filed
under the Bankruptcy Code with respect to Sublicensor and/or Licensor, to treat this Agreement or the License Agreement as terminated or to retain Sublicensee’s rights under this Agreement or the License Agreement, and under any agreements
supplemental to this Agreement or the License Agreement, with respect to such rights (including any embodiment of the rights to the extent protected by applicable non-bankruptcy law), as such rights existed immediately before the Sublicensor’s
and/or Licensor’s bankruptcy case commenced. If Sublicensee elects to retain such licensed rights under this Agreement or the License Agreement, then Sublicensee may exercise such licensed rights in accordance with the terms and conditions of
this Agreement or the License Agreement. Nothing contained herein shall limit any other rights provided to Sublicensee under the Bankruptcy Code, including Section 365(n) thereof.

and Trade Secrets. Licensor, Sublicensor and Sublicensee will at all times during the Term use commercially reasonable efforts to preserve and protect the confidentiality of all portions of the Know-How and any other information provided it such
Persons that constitute “trade secrets” as that term is defined in the Uniform Trade Secret Act (the “Trade Secrets”). Furthermore, if it comes to the attention of Licensor that any Trade Secret has been misappropriated by

 ARTICLE IX. 

CONFIDENTIALITY. 

9.1 Each Party shall maintain the terms of this Agreement in confidence and shall not disclose any information concerning the

Affiliates, (c) to any actual or prospective purchaser of all or a portion of such Party’s interest in the Facilities and (d) to any Person providing or evaluating a proposal to provide financing to the recipient Party or any direct
or indirect owner of such Party; provided in each case that the recipient Party shall provide to each Person to which disclosure is made a copy of this Section 9 and direct such Person to treat such information confidentially, and the
recipient Party shall be liable for any breach of the terms of this Section 9 by such Persons to which it makes any such disclosure. The foregoing restrictions will not apply (i) to information that is or becomes generally available to the
public otherwise than as a result of disclosure by the recipient Party, (ii) to information that is already in, or subsequently comes into, the recipient Party’s possession, provided that the source of such information was not, to the

to Law or stock exchange rules and regulations or is otherwise subject to legal, judicial, regulatory or self-regulatory requests for information or documents, or (iv) subject to Section 9.2 below, to the tax treatment or tax structure of
the transaction. 
 9.2 Notwithstanding anything to the contrary herein, each Party may disclose to any and all Persons,
without limitation of any kind, the tax treatment and tax structure of the transaction, provided, however, that any such information is required to be kept confidential to the extent necessary to comply with any applicable securities laws.
The tax structure and tax treatment of the transaction includes only those facts that may be relevant to understanding the purported or claimed U.S. federal and state income tax treatment or tax structure of the transaction and, to eliminate any
doubt, therefore specifically does not include information that either reveals or standing alone or in the aggregate with other information so disclosed tends of itself to reveal or allow the recipient of the information to ascertain the identity of
any parties involved in any of the transactions contemplated by this Agreement or any of the documents to be delivered in connection herewith. 

9.3 If any Party is required to disclose any information required by this Article IX to be maintained as confidential in a
judicial, administrative or governmental proceeding, such Party shall give the other Party at least 10 days’ prior written notice (unless less time is permitted by the applicable proceeding) before disclosing any such information in any said
proceeding and, in making such disclosure, the Party required to disclose the information shall disclose only that portion thereof required to be disclosed and shall cooperate with the other Party in the other Party’s attempts to seek to
preserve the confidentiality thereof, including if such Party seeks to obtain protective orders and/or any intervention.

ACCORDANCE WITH AND GOVERNED BY THE INTERNAL LAW OF THE STATE OF NEW YORK, WITHOUT REGARD TO THE CONFLICTS OF LAW PRINCIPLES THEREOF, INCLUDING SECTION 5-1401 OF THE NEW YORK GENERAL OBLIGATIONS LAW. THE PARTIES HEREBY IRREVOCABLY SUBMIT TO THE
EXCLUSIVE JURISDICTION OF ANY STATE OR FEDERAL COURT IN THE COUNTY OF NEW YORK IN THE STATE OF NEW YORK WITH RESPECT TO ANY ACTION OR PROCEEDING ARISING OUT OF OR RELATING TO THIS LEASE AND CONSENT TO THE SERVICE OF PROCESS IN ANY MANNER PERMITTED
BY LAW. EACH PARTY HERETO IRREVOCABLY AND UNCONDITIONALLY WAIVES RIGHT TO TRIAL BY JURY IN ANY ACTION, SUIT OR PROCEEDING RELATING TO A DISPUTE AND FOR ANY COUNTERCLAIM WITH RESPECT THERETO.

10.5 Assignment. No Party shall assign, sublease or otherwise transfer (collectively, an “Assignment”) this
Agreement or any of its rights hereunder without the prior written consent of the other Parties, and any purported Assignment made without such prior written consent shall be void. Notwithstanding the foregoing: 

(a) any Party may, without the need for consent from the other Parties, make an Assignment of this Agreement to an Affiliate of such

 10.6 Amendment;
Modification, and Waiver. This Agreement may not be amended or modified except by an instrument in writing signed by each of the Parties. Any failure of Sublicensee, Sublicensor, or Licensor to comply with any obligation, covenant, agreement, or
condition contained herein may be waived only if set forth in an instrument in writing signed by the Party to be bound thereby, but such waiver or failure to insist upon strict compliance with such obligation, covenant, agreement or condition shall
not operate as a waiver of, or estoppel with respect to, any other failure. 
 10.7 Severability of Provisions. If
any term or other provision of this Agreement is invalid, illegal, or incapable of being enforced by any rule of Applicable Law, or public policy, all other conditions and provisions of this Agreement shall nevertheless remain in full force and
effect so long as the economic or legal substance of the transactions contemplated herein are not affected in any manner materially adverse to any Party. Upon such determination that any term or other provision is invalid, illegal, or incapable of
being enforced, the Parties shall negotiate in good faith to modify this Agreement so as to effect the original intent of the Parties as closely as possible in a mutually acceptable manner in order that the transactions contemplated herein are
consummated as originally contemplated to the fullest extent possible. 
 10.8 Binding Effect; Third Parties. The

to any Person not a signatory to this Agreement.

entire agreement between the Parties hereto relating to the subject matter hereof. This Agreement expressly supersedes all prior agreements between the Parties relating to the subject matter hereof. 

10.10 Counterparts. This Agreement may be executed and delivered (including by facsimile transmission) in one or more
counterparts, all of which shall be considered one and the same agreement and shall become effective when one or more counterparts have been signed by each of the Parties and delivered to the other Parties, it being understood that all Parties need
not sign the same counterpart. 
 10.11 Survivability on Termination. The provisions of Article VIII, IX, and X,
and any other provision hereof which, by its terms, expressly provides that it survive termination of the Term, shall survive the termination of the Term for any reason. All other rights and obligations of the Parties shall cease upon termination of
the Term or other termination of this Agreement. 
 10.12 Further Assurances. Each Party shall execute and deliver
to any other Party such further documents, instruments and assurances as may be reasonably requested by such other Party to fulfill the intent of the Parties hereto.

 10.13 Construction. The words “this Agreement,” “herein,”
“hereby,” “hereunder,” and “hereof,” and words of similar import, refer to this Agreement as a whole (including all Annexes, Exhibits and Schedules) and not to any particular subdivision unless expressly so limited. The
words “this Section,” “this subsection,” and words of similar import, refer only to the Sections or subsections hereof in which such words occur. The word “or” is not exclusive, and the word “including” (in
its various forms) means “including without limitation.” Pronouns in masculine, feminine, or neuter genders shall be construed to state and include any other gender and words, terms, and titles (including terms defined herein) in the
singular form shall be construed to include the plural and vice versa, unless the context otherwise expressly requires. Unless the context otherwise requires, all defined terms contained herein shall include the singular and plural and the
conjunctive and disjunctive forms of such defined terms, and the term “Annex,” “Exhibit” or “Schedule” shall refer to an Annex, Exhibit or Schedule attached to this Agreement. 

10.14 Private Letter Ruling. If Sublicensee seeks a PLR, determination letter or other written guidance from the IRS (the
“IRS Guidance”) with respect to any aspect of the transactions contemplated in this Agreement or in relation to the Facilities, then the Parties shall consider in good faith and make such amendments to this Agreement as may be
necessary to permit Sublicensee to obtain the IRS Guidance or determination letter. Neither Sublicensor nor Licensor shall be required to agree to any such amendment that it reasonably determines, in good faith, is adverse to it in any material
respect; provided that neither Sublicensor nor Licensor shall withhold its agreement to any such amendment if Sublicensee has agreed to fully compensate Sublicensor or Licensor for any adverse economic effect on Sublicensor or Licensor
resulting from such amendment and such amendment would not cause any material adverse effect on Sublicensor or Licensor for which it cannot adequately be compensated by Sublicensee. 

10.15 Publicity. Sublicensor and Licensor agree that they will not, without the prior written consent of Sublicensee, in
each instance, (a) use in advertising, publicity, or otherwise the name of GS, or any Affiliate thereof (including Sublicensee), or any partner or employee of GS, or any Affiliate thereof (including Sublicensee), nor any trade name, trademark,
trade device, service mark, symbol or any abbreviation, contraction or simulation thereof owned by GS, or any affiliate thereof (including Sublicensee), or (b) represent, directly or indirectly, that any product or any service provided by
Licensor have been approved or endorsed by GS, or any Affiliate thereof (including Sublicensee). No public announcement of any kind regarding the existence or terms of this Agreement shall be made without the prior written consent of the other
Parties. For the avoidance of doubt, nothing in this Section 10.15 shall limit Licensor’s or Sublicensor’s obligation to disclose information pursuant to Article IX.

this Guaranty. 
 2. Guaranty. 

2.1 Irrevocable Guaranty. 

(a) The Guarantor hereby unconditionally and irrevocably guarantees, as a primary obligor and not merely as a surety, to the Guaranteed
Party and its successors, permitted indorsees, permitted transferees and permitted assigns that, upon written demand of payment made by the Guaranteed Party to the Guarantor, (i) all 

 

 2 

 
payment Obligations will be promptly paid in full, in United States dollars, when due in accordance with the provisions of the Transaction Documents and (ii) all performance Obligations will
be promptly and fully performed when due or required in accordance with the terms of the Transaction Documents. 
 (b) If legal
action is instituted, the Guarantor agrees to reimburse the Guaranteed Party on written demand for all reasonable attorney’s fees and disbursements and all other reasonable costs and expenses incurred by the Guaranteed Party in successfully
enforcing its rights under this Guaranty. Notwithstanding the foregoing, the Guarantor shall have no obligation to pay any such costs or expenses if, in any action or proceeding brought by the Guaranteed Party giving rise to a demand for payment of
such costs or expenses, it is finally adjudicated by a court of competent jurisdiction that the Guarantor is not liable to make payment or obligated to perform any further obligations under Section 2.1(a) of this Guaranty to the
Guaranteed Party hereunder. 
 (c) Each payment under this Guaranty shall be made in United States dollars. 

Notwithstanding anything in this Section 2.1, the Guarantor’s liability to guarantee a Company’s Obligations shall not exceed the
liability of such Company with respect to its Obligations under the terms of the Transaction Documents; provided, that, notwithstanding the foregoing provisions of this paragraph, or any other provisions hereof to the contrary, (a) the
Guarantor’s liability for the Obligations shall not be reduced by the amount of any costs and expenses recovered or recoverable by the Guaranteed Party under Section 2.1(b), and (b) if a Company’s liability in respect of
its Obligations is reduced due to any defense described in clauses (1) through (3) of the final paragraph of Section 2.3 hereof, the amount of such reduction shall not reduce the Guarantor’s liability for such
Company’s Obligations hereunder. 
 2.2 No Subrogation. The Guarantor will not exercise any rights that it may
acquire by way of subrogation or a right of contribution from the Company under this Guaranty, by any payment made hereunder or otherwise, until all of the Obligations shall have been indefeasibly paid in full. If any amount shall be paid to the
Guarantor on account of such subrogation or contribution rights at any time when all of the Obligations shall not have been paid in full, such amount shall be held in trust for the benefit of the Guaranteed Party to whom such Obligations are payable
and shall forthwith be paid to the Guaranteed Party to be credited and applied to such Obligations, whether matured or unmatured, in accordance with the terms of the applicable Transaction Document. If (i) the Guarantor shall make payment to
the Guaranteed Party of all or any part of the Obligations and (ii) all of the Obligations shall be indefeasibly paid in full, the Guaranteed Party will, at the Guarantor’s request and expense, execute and deliver to the Guarantor
appropriate documents in form and substance reasonably satisfactory to the Guaranteed Party, without recourse and without representation or warranty, necessary to evidence the transfer by subrogation to the Guarantor of an interest in the
Obligations resulting from such payment by the Guarantor. 
  

 3 

 2.3 No Effect on Guaranty. The obligations of the Guarantor under this Guaranty shall
not be altered, limited, impaired or otherwise affected by: 
 (a) any rescission of any demand for payment or performance of
any of the Obligations or any failure by the Guaranteed Party to make any such demand on a Company or any other guarantor or to collect any payments from a Company or any other guarantor or any release of a Company or any other guarantor;

 (b) any renewal, extension, modification, amendment, acceleration, compromise, waiver, indulgence, rescission, discharge,
surrender or release, in whole or in part, or any assignment or transfer, of any of the Transaction Documents or the Obligations or any other instrument or agreement evidencing, relating to, securing or guaranteeing any of the Obligations, or the
liability of any party to any of the foregoing or for any part thereof; 
 (c) any act or omission of the Guaranteed Party
relating in any way to the Obligations or to a Company, including any failure to bring an action against any party liable on the Obligations, or any party liable on any other guaranty of the Obligations; 

(d) any proceeding, voluntary or involuntary, involving bankruptcy, insolvency, receivership, reorganization, liquidation or arrangement
of a Company or any other guarantor or any defense which a Company or any other guarantor may have by reason of the order, decree or decision of any court or administrative body resulting from any such proceeding; and 

(e) any other act or omission that may or might in any manner or to any extent vary the risk of the Guarantor or that may or might
otherwise operate as a discharge of the Guarantor as a matter of law or equity, other than (1) the indefeasible payment in full in United States dollars of all the Obligations, and (2) as set forth in the next sentence. 

Notwithstanding the foregoing, the Guarantor shall be entitled to assert any defense which a Company may have under the Transaction
Documents to performance of any of its respective Obligations, other than defenses based upon (1) lack of authority, capacity, legal right or power of such Company to enter into and/or perform its obligations under the Transaction Documents,
(2) any insolvency, bankruptcy, reorganization, arrangement, composition, liquidation, dissolution or similar proceeding with respect to such Company or (3) the nonexistence, invalid formation, dissolution, merger or termination of such
Company. 
  

 4 

 2.4 Continuing Guaranty; Termination. This Guaranty shall be construed as a
continuing, absolute and unconditional guaranty of payment and performance when due, and not of collection only, and the obligations of the Guarantor hereunder shall not be conditioned or contingent upon the pursuit by the Guaranteed Party at any
time of any right or remedy against a Company or against any other person which may be or become liable in respect of all or any part of the Obligations. 

2.5 Reinstatement of Guaranty. This Guaranty shall continue to be effective, or be reinstated, as the case may be, if at any time
payment, or any part thereof, of any of the Obligations is avoided, rescinded or must otherwise be restored or returned by the Guaranteed Party to a Company or its representative or to any other guarantor for any reason including as a result of any
insolvency, bankruptcy or reorganization proceeding with respect to a Company or the Guarantor, all as though such payment had not been made. 

2.6 No Consequential Damages. In no event shall Guarantor be subject to any consequential, exemplary, equitable, loss of profits,
punitive, tort or other similar damages. 
 3. Representations and Warranties of the Guarantor. The Guarantor
hereby represents and warrants to the Guaranteed Party, as follows: 
 (a) The Guarantor is a corporation, validly existing and
in good standing under laws of the State of Colorado. 
 (b) The Guarantor has full power, authority and legal right to execute
and deliver this Guaranty and to perform its obligations hereunder. 
 (c) The execution, delivery and performance of this
Guaranty have been duly authorized by all necessary corporate action on the part of the Guarantor. 
 (d) This Guaranty has been
duly executed and delivered by the Guarantor and constitutes the legal, valid and binding obligation of the Guarantor, enforceable against it in accordance with its terms, except as enforceability may be limited by bankruptcy, insolvency or other
similar laws affecting creditors’ rights generally or by general principles of equity. 
 (e) All consents, authorizations,
approvals and clearances (including, without limitation, any necessary exchange control approval) and notifications, reports and registrations requisite for its due execution, delivery and performance of this Guaranty have been obtained from or, as
the case may be, filed with the relevant Governmental Authorities having jurisdiction and remain in full force and effect and all conditions thereof have been duly complied with and no other action by, and no notice to or filing with, any
Governmental Authority having jurisdiction is required for such execution, delivery or performance. 
  

 5 

 (f) The execution and delivery by the Guarantor of this Guaranty do not and the performance
by Guarantor of its obligations hereunder will not, (i) violate or require any filing or notice under any Law applicable to Guarantor (other than the filing of this Guaranty with the United States Securities and Exchange Commission under the
federal securities laws applicable to U.S. public companies), (ii) conflict with or cause a breach of any provision in the certificate of incorporation, by-laws or other organizational document of Guarantor, or (iii) cause a breach of,
constitute a default under, cause the acceleration of, create in any party the right to accelerate, terminate, modify or cancel, or require any authorization, consent, waiver or approval under any contract, license, instrument, decree, judgment or
other arrangement to which Guarantor is a party or under which it is bound or to which any of its assets are subject (or result in the imposition of a Lien, other than Permitted Liens, upon any such assets) except (in the case of this
clause (iii)) for any that would not reasonably be expected to have a Material Adverse Effect. 
 4. Election of
Remedies. Each and every right, power and remedy herein given to the Guaranteed Party, or otherwise existing, shall be cumulative and not exclusive, and be in addition to all other rights, powers and remedies now or hereafter granted or
otherwise existing. Each and every right, power and remedy whether specifically herein given or otherwise existing may be exercised, from time to time and as often and in such order as may be deemed expedient by the Guaranteed Party. 

5. Effect of Delay or Omission to Pursue Remedy. No waiver by the Guaranteed Party of any right, power or remedy, or delay
or omission by the Guaranteed Party in the exercise of any right, power or remedy which they may have shall impair any such right, power or remedy or operate as a waiver as to any other right, power or remedy then or thereafter existing. Any waiver
given by the Guaranteed Party of any right, power or remedy in any one instance shall only be effective in that specific instance and only for the purpose for which given, and will not be construed as a waiver of any right, power or remedy on any
future occasion. 
 6. Guarantor’s Waivers. The Guarantor waives any and all notice of the creation, renewal,
extension or accrual of any of the Obligations and notice of or proof of reliance by the Guaranteed Party upon this Guaranty or acceptance of this Guaranty; the Obligations, and any of them, shall conclusively be deemed to have been created,
contracted, incurred, renewed, extended, amended or waived in reliance upon this Guaranty, and all dealings between the Guarantor and the Guaranteed Party shall likewise be conclusively presumed to have been had or consummated in reliance upon this

  

 6 

 
Guaranty. The Guarantor waives presentment, demand (other than demand delivered pursuant to Section 2.1(a) hereof), notice, and protest of all instruments included in or evidencing

Guaranty. 
 7. Amendment. This Guaranty may not be modified, amended, terminated or revoked, in whole or in part,
