followed by the words “without limitation.” The words “hereof,” “herein,” “hereto” and “hereunder” and words of similar import when used in this Agreement shall refer to this Agreement as a whole and
not to any particular provision of this Agreement. The definitions contained in this Agreement are applicable to the singular as well as the plural forms of such terms and to the masculine as well as to the feminine and neutral genders of such term.
Any agreement, instrument or statute defined or referred to herein shall mean such agreement, instrument or statute as from time to time amended, modified or supplemented. References to a Person are also to its permitted successors and assigns and,

 ARTICLE II 
 LICENSE 
 Section 2.1 License of Licensed Intellectual Property. Effective
as of the Closing, on the terms and conditions set forth herein, Licensor hereby grants to Licensee and its Affiliates a perpetual, worldwide, royalty-free, fully paid up, exclusive license to use the Licensed Intellectual Property (other than the
New IP) in the Field. Effective as of the date of acquisition or development of any New IP, on the terms and conditions set forth herein, Licensor hereby grants to Licensee and its Affiliates a perpetual, worldwide, royalty-free, fully paid up,
exclusive license to use such New IP in connection with the Field. The foregoing licenses include the right (a) to make, have made, use, import, export, distribute, offer to sell and sell products under the Licensed Intellectual Property, and
(b) to publish, display, reproduce, copy, modify, improve, create derivative works of, enhance, and otherwise exploit such Licensed Intellectual Property. The foregoing licenses shall be sublicensable solely as is reasonably necessary in
connection with the receipt of goods and services by Licensee and its Affiliates but is not sublicensable pursuant to this Section 2.1 for use by any third Person for such third Person’s own benefit. Licensor shall promptly advise
Licensee in writing of any acquisition or development of any New IP. For the avoidance of doubt, nothing in this Agreement shall prohibit Licensor from using the Licensed Intellectual Property for applications or other uses that are outside the
Field. 
 Section 2.2 Requests for Licensed Intellectual Property. To the extent that Licensee becomes aware that its personnel
is not in possession of (a) copies of all documentation (either in electronic or hard copy) that is in Licensor’s possession or control as of the Closing Date and that constitutes Licensed Intellectual Property and/or is reasonably
necessary for the use of the Licensed Intellectual Property, and/or (b) tangible embodiments of the Licensed Intellectual Property (including copies of all Software included in the Licensed Intellectual Property) that is in Licensor’s
possession or control as of the Closing Date, promptly following Licensee’s request, Licensor will confidentially provide to Licensee copies (at Licensee’s option, either in electronic (to the extent available) or hard copy) of such
documentation and/or tangible embodiments as such documentation and/or tangible embodiments existed as of the Closing Date. Notwithstanding anything to the contrary in this Section 2.2, with respect to Licensed Intellectual Property that
is New IP, promptly after such coming into Licensor’s possession or control, Licensor shall confidentially provide to Licensee (at Licensee’s 

  

 4 








 
option, either in electronic (to the extent available) or hard copy) (a) copies of all documentation that is in Licensor’s possession or control
and constitutes such Licensed Intellectual Property and/or is reasonably necessary for the use of such Licensed Intellectual Property, and/or (b) tangible embodiments of such Licensed Intellectual Property (including copies of all Software
included in such Licensed Intellectual Property) that is in Licensor’s possession or control. If Licensee has a reasonable basis to believe that Licensor has failed to either (i) provide to Licensee copies of such documentation and/or
tangible embodiments or (ii) advise Licensee of any New IP in accordance with Section 2.1, then, upon reasonable notice to Licensor and during normal business hours, Licensee shall have the right to confidentially audit and inspect
the books and records relating to the acquisition and development of such Intellectual Property (and make confidential copies thereof); provided, however, that if any Member of Licensee is a Competitor, no such right of audit shall
apply. 
 Section 2.3 Right to License Additional Intellectual Property. 
 (a) If, during the Future Licensing Period, Licensor or any of its Affiliates (other than Excluded Affiliates) acquires or develops any
Intellectual Property relating to the Field, including, without limitation, a carbon application for control of pollutants developed by Licensor for control of pollutants other than mercury (but in each case other than New IP) (hereinafter, the
“Additional IP”), Licensor shall promptly advise Licensee in writing thereof and shall provide such technical information related thereto on a confidential basis to allow Licensee to evaluate such Intellectual Property. If Licensee
has a reasonable basis to believe that Licensor has failed to advise Licensee of any such Intellectual Property acquired or developed during the Future Licensing Period, Licensee shall have the same audit rights with respect to such Intellectual
Property as it has with respect to New IP pursuant to the last sentence of Section 2.2. 
 (b) With respect to each
item of Additional IP, Licensor shall (and shall cause its applicable Affiliate(s) (other than Excluded Affiliates) to) offer to Licensee and its Subsidiaries a perpetual, worldwide, exclusive license to use such Additional IP in connection with the
Field, on such additional terms as Licensor or such Affiliate is willing to accept. If Licensor’s and such Affiliates’ rights in such Additional IP are less than those described in the immediately preceding sentence, then Licensor and such
Affiliates shall only be obligated to offer the maximum rights that Licensor and such Affiliates have with respect to such Additional IP, provided that such limitations were not imposed through any breach of this Agreement. Licensee shall advise
Licensor within thirty (30) days after the later of (i) receiving written notice of such new Intellectual Property (or, in the case of any such Intellectual Property disclosed through audit, thirty (30) days after disclosure of such
new Intellectual Property in the audit) and (ii) receiving an offer to license such new Intellectual Property (including the material terms of such license), whether Licensee wishes to license such Intellectual Property from Licensor or such
Affiliate on the offered terms. If Licensee does not accept Licensor’s offer to license Additional IP within thirty (30) days and the parties have not otherwise reached an agreement within such period through good-faith negotiation, then
Licensor and its Affiliates may offer to any other Person a perpetual, worldwide, exclusive license to use such Intellectual Property in connection with any or all of the Field so long as the terms of such offer are no more favorable than the terms
offered to, or the best terms offered by, Licensee during the course of such 

  

 5 








 
negotiations. If any other Person (a “Proposed Licensee”) is willing to exclusively license such Intellectual Property from Licensor or its
Affiliate(s) in connection with any or all of the Field on a non-worldwide basis or for less than a perpetual term, but the other material terms of the license are less favorable than the terms of the best offer provided by Licensee, then prior to
granting such license to such Proposed Licensee, Licensor shall (i) notify Licensee of the name and address of such Proposed Licensee, (ii) provide a reasonably detailed summary of the price and other material terms of the proposed
arrangement with such Proposed Licensee, and (iii) offer such license to Licensee on the same terms. If Licensee does not want to accept such license, Licensor may grant such license on such terms to such Proposed Licensee. If there is any
Proposed Licensee willing to license such Intellectual Property from Licensor or its Affiliate(s) in connection with any or all of the Field on a non-exclusive basis, but the other material terms of the license are less favorable than the terms of
the best offer provided by Licensee, then Licensor shall provide a reasonably detailed summary of the price and other material terms of the proposed arrangement with such Proposed Licensee and offer such license to Licensee on the same terms.

 (c) Notwithstanding anything to the contrary in paragraphs (a) and (b) of this Section 2.3 above, but
subject to this Section 2.3(c), if, during the Future Licensing Period, Licensor or any of its Affiliates acquires or develops any Intellectual Property relating exclusively or primarily to the manufacture, production, processing and/or
supply of activated carbon for the control of carbon dioxide emissions, Licensor shall have no obligation to offer a license thereto to Licensee; provided, however, that prior to offering such Intellectual Property to any Person for
any application or use that would act as a substitute for, or would otherwise eliminate or significantly reduce the need for, control of mercury emissions from coal fired power plants, Licensor shall (and shall cause its applicable Affiliate(s) to)
comply with paragraphs (a) and (b) of this Section 2.3 with respect to such Intellectual Property. 
 ARTICLE III

the world. 
 Section 3.2 Ownership of Derivative Works. Licensee acknowledges and agrees that (a) to the extent that
Licensee or any of its Affiliates creates derivative works of the Licensed Intellectual Property pursuant to Section 2.1, ownership of the new original elements of any such derivative work shall reside with Licensee and its Affiliates,

Agreement, Licensor shall have no obligation whatsoever to provide support, maintenance, revisions, updates, upgrades, enhancements, new versions, bug fixes, patches or any other assistance of any kind to Licensee in connection with the Licensed
Intellectual Property.

 Section 4.1 Notice of Unauthorized Use. In the event that a Party (or any of its
Affiliates) becomes aware of any infringement, misappropriation or other violation by any third Person of the Licensed Intellectual Property (each, an “Unauthorized Use”), such Party shall promptly provide the other Party with
written notice thereof.

with Licensor in investigating, prosecuting and settling any enforcement action instituted by Licensor against any Person engaging in an Unauthorized Use. Licensor may bring such action in the name of Licensor alone or in the name of both Licensor
and Licensee (including any of Licensee’s Affiliates) with counsel of Licensor’s choosing, but at Licensor’s expense. Licensee, at its own expense, shall have the right to participate with counsel of its own choice in the
investigation, prosecution and/or settlement of any such enforcement action instituted by Licensor. All proceeds recovered in such enforcement action shall first be remitted to each of the Parties to reimburse them, on a pro rata basis, for their
respective reasonable out-of-pocket costs and expenses incurred in connection with such action, and any remaining proceeds shall be retained by Licensor. 
 Section 4.3 Enforcement by Licensee. In the event that Licensor has not taken reasonable steps to challenge and attempt to eliminate an Unauthorized Use within thirty (30) days after written notice
from Licensee of its intent to itself challenge and attempt to eliminate such Unauthorized Use, Licensee shall have the right, but not the obligation, to challenge and attempt to eliminate the Unauthorized Use. In the event that Licensee decides to
bring an enforcement action, Licensor shall reasonably cooperate (and shall require its Affiliates to reasonably cooperate), at Licensee’s expense, with Licensee in investigating, prosecuting and settling any enforcement action instituted by
Licensee against any Person engaging in an Unauthorized Use. Licensee may bring such action in the name of Licensor alone or in the name of both Licensor and Licensee (including any of Licensee’s Affiliates) with counsel of Licensee’s
choosing, but at Licensee’s expense. Licensor, at its own expense, shall have the right to participate with counsel of its own choice in the investigation, prosecution and/or settlement of any such enforcement action instituted by Licensee. All
proceeds recovered in such enforcement action shall first be remitted to each of the Parties to reimburse them, on a pro rata basis, for their respective reasonable out-of-pocket costs and expenses incurred in connection with such action, and any
remaining proceeds shall be retained by Licensee. 
 Section 4.4 No Right to Enforce. Except to the extent set forth in this
Article IV, Licensee shall not have the right to prosecute or settle an action against any Person who engages in an Unauthorized Use.

 ARTICLE V 
 CONFIDENTIALITY 
 Section 5.1 Confidentiality. Except as expressly permitted under this
Agreement, Licensee, on behalf of itself and its Affiliates, agrees not to disclose to any third party any confidential information included in the Licensed Intellectual Property and agrees to treat such Licensed Intellectual Property in the same
manner (but in no event using less than a commercially reasonable degree of care) as Licensee treats other similarly sensitive Intellectual Property owned by Licensee; provided that Licensee’s obligation hereunder shall not apply to
information that: 
 (a) is or becomes public knowledge without any action or omission by, or involvement of, Licensee or any
of its Affiliates; 
 (b) is obtained by Licensee or any of its Affiliates without restrictions on use or disclosure from a
third Person who, to Licensee’s or such Affiliates’ knowledge, breached no obligation of confidentiality in disclosing the information; or

Licensee: 
 (a) to Licensee’s directors, officers, employees, agents, auditors, consultants, financial advisors,
financing sources (whether actual or potential) and permitted sublicensees; provided that Licensee ensures that any such Persons are bound in writing by obligations of confidentiality and non-disclosure at least as strict as those contained
in this Article IV; and 
 (b) pursuant to any judicial or governmental order, or to a regulatory authority or under
other operation of law; provided that Licensee (i) promptly gives Licensor notice of the circumstances of the required disclosure prior to making any such disclosure so that Licensor, in its sole discretion, may seek an appropriate
protective order or other appropriate remedy from the proper authority, (ii) takes all commercially reasonable steps necessary to assist Licensor in seeking such order or other remedy, and (iii) if Licensor is not successful in precluding
the requesting legal body from requiring the disclosure of its non-public Licensed Intellectual Property, limits disclosures to the portion of non-public Licensed Intellectual Property specifically required to be disclosed and exercises all
reasonable efforts to obtain reliable assurances that confidential treatment will be accorded the non-public Licensed Intellectual Property. 
 Section 5.3 Unauthorized Disclosure. If, at any time, Licensee determines that any of its directors, officers, employees, agents, auditors, consultants, or sublicensees has disclosed, or sought to disclose, confidential Licensed
Intellectual Property in violation of this Intellectual Property Agreement, or that Licensee or any of its personnel has engaged in activities that may lead to the 

  

 8 








 
unauthorized use or disclosure of any confidential Licensed Intellectual Property, Licensee shall immediately take action to prevent any further unauthorized
use or disclosure, including where appropriate, terminating the applicable personnel’s access to such confidential Licensed Intellectual Property and immediately notifying Licensor. Licensee will cooperate with Licensor in investigating any
apparent unauthorized disclosure or use of the confidential Licensed Intellectual Property. 
 Section 5.4 Employees;
Consultants. During the Future Licensing Period, (i) Licensor shall cause all officers, directors (other than outside directors) and key employees to enter into proprietary rights agreements vesting or assigning ownership of Intellectual
Property to Licensor in a form substantially similar to Licensor’s employment agreements with Michael Durham and C. Jean Bustard as in effect on the date hereof and (ii) Licensor shall use reasonable best efforts to cause key consultants

 Section 7.9 Waiver of Jury Trial. TO THE MAXIMUM EXTENT PERMITTED BY LAW, EACH OF THE PARTIES
TO THIS AGREEMENT HEREBY WAIVES ITS RESPECTIVE RIGHTS TO A JURY TRIAL OF ANY CLAIM OR CAUSE OF ACTION BASED UPON OR ARISING OUT OF THIS AGREEMENT OR ANY DEALINGS BETWEEN THEM RELATING TO THE SUBJECT MATTER OF THIS AGREEMENT AND THE RELATIONSHIP THAT
IS BEING ESTABLISHED. EACH PARTY ALSO WAIVES ANY BOND OR SURETY OR SECURITY UPON SUCH BOND WHICH MIGHT, BUT FOR THIS WAIVER, BE REQUIRED OF ANY OF THE OTHER PARTIES. THE SCOPE OF THIS WAIVER IS INTENDED TO BE ALL-ENCOMPASSING OF ANY AND ALL DISPUTES
THAT MAY BE FILED IN ANY COURT AND THAT RELATE TO THE SUBJECT MATTER OF THIS AGREEMENT, INCLUDING CONTRACT CLAIMS, TORT CLAIMS, BREACH OF DUTY CLAIMS, AND ALL OTHER COMMON LAW AND STATUTORY CLAIMS. EACH PARTY ACKNOWLEDGES THAT THIS WAIVER IS A
MATERIAL INDUCEMENT TO ENTER INTO A BUSINESS RELATIONSHIP, THAT EACH HAS ALREADY RELIED ON THE WAIVER IN ENTERING INTO THIS AGREEMENT AND THAT EACH WILL CONTINUE TO RELY ON THE WAIVER IN THEIR RELATED FUTURE DEALINGS. EACH PARTY FURTHER WARRANTS AND
REPRESENTS THAT IT HAS REVIEWED THIS WAIVER WITH ITS LEGAL COUNSEL, AND THAT EACH KNOWINGLY AND VOLUNTARILY WAIVES ITS JURY TRIAL RIGHTS FOLLOWING CONSULTATION WITH LEGAL COUNSEL. THIS WAIVER IS IRREVOCABLE, MEANING THAT IT MAY NOT BE MODIFIED
EITHER ORALLY OR IN WRITING, AND THE WAIVER SHALL APPLY TO ANY SUBSEQUENT AMENDMENTS, RENEWALS, SUPPLEMENTS OR MODIFICATIONS TO THIS AGREEMENT OR TO ANY OTHER DOCUMENTS OR AGREEMENTS RELATING TO THE TRANSACTION CONTEMPLATED HEREBY. IN THE EVENT OF
LITIGATION, THIS AGREEMENT MAY BE FILED AS A WRITTEN CONSENT TO A TRIAL BY THE COURT. 
 Section 7.10 Counterparts. This
Agreement may be executed in any number of counterparts, any of which may be delivered via facsimile or PDF, each of which will be deemed an original, but all of which together will constitute one and the same instrument. 
 Section 7.11 Entire Agreement, Conflict. This Agreement, together with the Joint Development Agreement and the Master Services Agreement,
constitute the entire agreement between the Parties with respect to the subject matter hereof, and supersede and cancel all prior agreements, negotiations, correspondence, undertakings, understandings and communications of the Parties, oral and
written, with respect to the subject matter hereof. If there is a conflict between the terms of this Agreement, and the Joint Development Agreement, the terms of this Agreement shall govern; provided that nothing herein shall be deemed to
prevent Licensee from exercising any rights it may have pursuant to the Joint Development Agreement. 
 Section 7.12 Assignment.

 (a) Except as expressly provided in this Section 7.12, neither Party may assign this Agreement or any of its
rights, interests or obligations hereunder (whether by operation of law or otherwise) without the prior written consent of the other Party. 

  

 13 








 (b) Notwithstanding Section 7.12(a) above, without the prior written consent of Licensee,
Licensor may assign this Agreement, in whole or in part, in connection with and to the extent of its assignment or other transfer of any of the Licensed Intellectual Property. 
 (c) Notwithstanding Section 7.12(a) above, without the prior written consent of Licensor, Licensee may assign this Agreement, in whole or in
part (i) to any of its Affiliates, (ii) to any third Person in connection with an acquisition of the Licensee (whether by merger, consolidation, sale of assets, sale or exchange of stock, or otherwise), and/or (iii) to any third
Person in connection with an acquisition of a discrete business unit or division of the Licensee (whether by merger, consolidation, sale of assets, sale or exchange of stock, or otherwise). For the avoidance of doubt, any permitted “assignment
in part” of this Agreement shall not preclude Licensee’s or its Affiliates’ use of the Licensed Intellectual Property pursuant to this Agreement following the effective date of such partial assignment in connection with the assets
retained by Licensee or its Affiliates. 
 (d) Notwithstanding anything to the contrary in this Section 7.12, either Party may
assign (including by way of a pledge) to its lenders or other financing sources any or all of its rights hereunder as collateral security (which assignment shall not relieve such assigning Party of its obligations hereunder). 
 (e) Any purported assignment in violation of this Section 7.12 shall be null and void. 
 Section 7.13 Binding on Successors and Assigns. This Agreement shall be binding upon and shall inure to the benefit of the Parties and
Licensee’s Affiliates and permitted sublicensees, and their respective successors and permitted assigns.
