This Second Amendment (this “Amendment”)
to the BKV Corporation 2020 Employee Stock Purchase Plan (the “Plan”) is made by BKV Corporation (the “Company”)
this 21st day of April, 2022.


 


WHEREAS, the Company desires
to expand the Plan’s eligibility requirements to include employees of the Company’s affiliates and subsidiaries, subject to
approval of the Company’s stockholders as required by Section 8.7 of the Plan; and


 


WHEREAS, the Company desires
to remove a typographical error contained in Section 2.17.


 


NOW THEREFORE, the Plan is
amended effective as of March 17, 2022, as follows:


 


		1.	Section 2.5 is amended by adding the following language to the end of such section:



 


For purposes of Section 2.7 (first
sentence), Section 8.2, and Section 8.5, “Company” shall include any affiliate or subsidiary of the Company, as
such terms are defined under Section 2.6.


 


		2.	Section 2.6 is amended and
restated to read as follows:



 


2.6           Eligible
Employee. An “Eligible Employee” means any Employee of the Company, any affiliate or subsidiary of the Company, or BNAC
who (i) has been employed by the Company, any affiliate or subsidiary of the Company, or BNAC, for at least twelve (12) consecutive
months, and (ii) is customarily scheduled to work at least forty (40) hours per week. For purposes of this section and the Plan,
 “affiliate of the Company” means a corporation or other entity (including a partnership or a limited liability company) that
is engaged in the business of oil and gas exploration and production and is controlled by the Company (where “control” means
ownership of more than fifty percent (50%) of the voting equity of any entity), and “subsidiary of the Company” means any
corporation or other entity, whether domestic or foreign, that is engaged in the business of oil and gas exploration and production and
in which the Company has or obtains, directly or indirectly, an ownership interest of more than fifty percent (50%) by reason of stock
ownership or otherwise. For the avoidance of doubt, “affiliate or subsidiary of the Company” specifically includes Kalnin
Ventures LLC, BKV Barnett, LLC, BKV Operating, LLC, BKV Chelsea, LLC, and BKV Chaffee Corners, LLC, and specifically excludes BKV-BPP
Power, LLC and any business developed by the Company for the purpose of carbon capture, utilization and storage (“CCUS”).


 


		3.	Section 2.17 of the Plan
is amended by amending and restating the first sentence of such Section to read as follows:



 


“Stock Purchase Account”
means a noninterest-bearing account consisting of all amounts deposited by a Participant for the purpose of purchasing shares of Common
Stock for such Participant under the Plan reduced by all amounts applied to the purchase of shares of Common Stock for such Participant
under the Plan.


 






     


     


    

 


IN WITNESS WHEREOF, the undersigned,
on behalf of BKV Corporation, has executed this Second Amendment to the BKV Corporation 2020 Employee Stock Purchase Plan document effective
as of the 21st day of April 2022.
