purposes of this Agreement without the need for further approval by the Board.

 

(b)       The
Board shall review each Budget, including the Initial Budget, from time to time as requested by the Manager during the capital
year to which such Budget relates and the Budget shall be amended or modified to reflect any amendments or modifications thereto
approved by the Board and as so modified or amended shall thereafter constitute the Budget for the remainder of the calendar year
to which such Budget relates. Each Budget, including the Initial Budget, shall be divided into at least two sections as follows:
(i) a section setting forth expenditures which are fundamental to the operation of the Company and its Subsidiaries and continuing
and ongoing operation of their producing assets (the “Baseline Budget”) and (ii) a section setting forth
expenditures related to the development of and growth or development capital expenditures related to the assets of the Company
and its Subsidiaries (the “Development Budget”).

“Proposed Budget”) setting forth the anticipated revenues and expenses of the Company for such calendar
year in a format consistent with the Initial Budget, which shall include such information requested by the Board.

 

(d)       Expenditures
in a Budget may extend over more than one calendar year because such expenditures represent activities or operations that require
commitments in excess of one calendar year. Once such expenditures have been approved by the Board as part of a Budget, unless
the Board determines otherwise in accordance with its review of a Budget pursuant to Section 2.8(b), such expenditures shall
not be required to be resubmitted for approval on an annual or other periodic basis, but instead all such items, until completed,
automatically shall be included in future Budgets (subject to limits and amounts as previously approved) as items which have already
been approved.

 

(e)       If
the Board does not approve a Proposed Budget for a calendar year on or prior to the December 20 preceding January 1 of
the calendar year to which such Proposed Budget relates, the officers shall use good faith efforts to prepare or to cause to be
prepared a revised Proposed Budget for approval by the Board. Each Proposed Budget approved hereunder by the Board in accordance
with Section 2.4(a)(i) shall be deemed a “Budget.”

 

(f)       To
the extent that any Proposed Budget is not approved by the Board in accordance with Section 2.4(a)(i) by the first
day of the calendar year to which such Proposed Budget relates, then, until a Proposed Budget for such calendar year is approved
by the Board in accordance with Section 2.4(a)(i), the Baseline Budget for such calendar year shall be equal to the
Baseline Budget for the immediately preceding calendar year (excluding non-recurring items but including recurring maintenance
capital expenditures).

 

(g)       The
Company shall not incur expenses or capital expenditures in excess of amounts set forth in the Budget without prior approval of
the Board in accordance with Section 2.4(a)(ii), except (i) Permitted Variances and (ii) as set forth in Section 2.8(h).

 

    13

     

    

 

(h)       Notwithstanding
anything to the contrary in this Agreement, the Company is expressly authorized to make Emergency Expenditures without prior authorization
or approval of the Board when necessary or advisable, in the judgment of the officers of the Company or the Manager, pursuant to
Prudent Industry Practices, to deal with emergencies, including explosions, fires, spills, or any other similar event, which may
endanger property, lives, or the environment. The officers of the Company or the Manager shall as soon as practicable report to
the Board the nature of any such emergency which arises, the measures he intends to take in respect of such emergency and the estimated
related expenditures.

 

Section 2.9Conflict
Activities.

 

(a)       Notwithstanding
anything to the contrary in this Agreement, any Conflict Activity shall be conducted by and under the direction of, and subject
to the sole approval by, the Directors that have been appointed by a Non-Conflicted Member and neither the Conflicted Member nor
the Directors appointed by the Conflicted Member shall have the right to vote or participate in any meeting of the Board regarding
such Conflict Activity or any approval in connection with any action by the Board in respect of such Conflict Activity and the
presence of any Directors appointed by the Conflicted Member shall not be required for purposes of determining the presence of
a quorum in connection with any such action.

 

(b)       No
officer of the Company that is also an officer, director, member, manager, stockholder, partner or employee of a Conflicted Member
(or one of its Affiliates) shall have any obligation to take or refrain from taking any action on behalf of the Company with respect
to such Conflict Activity except to provide information, documents and other related items reasonably requested by the Company
or the Board in connection with such Conflict Activity (provided that such Person shall not be required to provide such information,
documents or other items if doing so would require such Person to violate any applicable confidentiality restrictions (following
a request of the waiver thereof) or waive or violate any legal professional privilege or similar duty of confidentiality). Except
with respect to such Person’s failure to provide information, documents or other related items requested by the Company in
connection with such Conflict Activity in violation of the foregoing or to provide testimony, give evidence or otherwise participate
in any suit, litigation, arbitration or other dispute resolution proceeding involving the Conflicted Member, any such Person’s
failure or refusal to take or refrain from taking any such action shall not constitute (i) a breach of any duty, fiduciary or otherwise,
if any, owed by such Person to the Company or (ii) gross negligence or willful misconduct on the part of such Person.

 

(c)       Notwithstanding
anything to the contrary in this Agreement, at any time that a Member is a Defaulting Member, this Section 2.9 shall not
apply for the benefit of such Member, the Directors that have been appointed by such Defaulting Member shall have no rights under
this Section 2.9 with respect to any Conflict Activity, and the Directors appointed by the Non-Defaulting Member shall have
authority to act on behalf of the Company with respect to such Conflict Activity.

be submitted to, and resolved by, Ernst & Young LLP or, if such Person is unable or unwilling to serve in such capacity, by

(a)       The
Company shall have one or more Members with Interests designated as Units. Initially there shall be three classes of Units, designated
“Class A Units”, “Class B Units” and “Class C Units”.
The names, addresses and number and class of Units of each of the initial Members are set forth in Exhibit A attached
hereto. To the extent of their holdings of Class A Units, Members holding Class A Units shall be referred to as “Class
A Members” and to the extent of their holdings of Class B Units, Members holding Class B Units shall be referred
to as “Class B Members” and to the extent of their holdings of Class C Units, Members holding Class C
Units shall be referred to as “Class C Members.”

 

(b)       Subject
to Section 2.4(a)(xi), Section 2.4(a)(xii) and Article VI, any Person to which Units are issued
by the Company after the date hereof shall be admitted to the Company as a Member on the date of issuance of such Units.

 

(c)       Any
Person to which Units are Transferred as permitted by Article VI shall be admitted to the Company as a Member with
respect to the Units acquired on the date upon which such Transfer has been effected and the requirements set forth in Section
6.1 and Section 6.7 have been satisfied.

 

(d)       Class
A Units shall be issued from time to time as provided in this Article III and be the only Interests entitled to vote
and each Class A Member shall have a number of votes equal to the number of Class A Units it holds.

 

    15

     

    

 

(e)       Class
B Units.

 

(i)       The
class of Units designated as Class B Units shall consist solely of one thousand (1,000) Class B Units, all of which currently are
issued and held by Carbon as the Class B Member.

 

(ii)       The
Class B Member shall have no obligation to make any capital contributions to the Company in exchange for or on account of the Class
B Units.

 

(iii)       Subject
to Section 12.6, the Class B Units shall have no voting rights on any matter, including amendments to this Agreement.

 

(iv)       The
Company and each Member agree to treat each Class B Unit as a separate “profits interest” within the meaning of Rev.
Proc. 93-27, 1993-2 C.B. 343. Notwithstanding anything herein to the contrary, distributions to each Class B Member pursuant to
Section 5.4 hereof (solely with respect to such Class B Units) shall be limited to the extent necessary so that each Class
B Unit qualifies as a “profits interest” under Rev. Proc. 93-27, and this Agreement shall be interpreted accordingly.
In the event that distributions to a Class B Member pursuant to Section 5.4 hereof are limited as a result of the preceding
sentence of this Section 3.1(e)(iv), the Manager is authorized to adjust future distributions to the Members in whatever
manner it deems appropriate so that, after such adjustments are made, each Member receives, to the maximum extent possible, an
amount of distributions equal to the amount of distributions such Member would have received were such sentence not part of this
Agreement; provided, that any such adjustment to distributions shall be consistent with the treatment of the Class B Units as “profits
interests.” Additionally, in accordance with Rev. Proc. 2001-43, 2001-2 C.B. 191, the Company shall treat each Class B Member
as the owner of a Class B Unit from the date it is granted, and shall file its IRS Form 1065, and issue appropriate Schedule K-1s
to such Class B Members, allocating to such Class B Members their distributive shares of all items of income, gain, loss, deduction
and credit associated with such Class B Units. Each Class B Member agrees to take into account such distributive share in computing
its U.S. federal income tax liability for the entire period during which it holds the Class B Unit. The Company and each Member
agree not to claim a deduction (as wages, compensation or otherwise) for the Fair Market Value of such Class B Units issued to
Class B Members at any time. The undertakings contained in this Section 3.1(e)(iv) shall be construed in accordance with
Section 4 of Rev. Proc. 2001-43. The provisions of this Section 3.1(e)(iv) shall apply regardless of whether or not a Class
B Member files an election pursuant to Section 83(b) of the Code.

held by Carbon as the sole Class C Member.

 

(ii)       Other
than the Class C Non-Cash Capital Contribution, the Class C Member shall have no right or obligation to make any capital contributions
to the Company in exchange for or on account of the Class C Units.

 

(iii)       Subject
to Section 12.6, the Class C Units shall have no voting rights on any matter, including amendments to this Agreement.

 

(g)       Old
Ironsides as Class A Member. Notwithstanding anything herein to the contrary, with respect to OIE Fund II-A and/or OIE
Fund II-B in its or their capacity as Class A Member, any right, approval, consent, vote or similar action of Old Ironsides
contemplated under this Agreement may be exercised by either OIE Fund II-A or OIE Fund II-B acting unilaterally or by OIE Fund

their respective officers or directors (in their capacities as such), making any investment in, acquiring any ownership interest
in, or participating in the development of any oil and gas properties (e.g., working interests or royalty interests), operations

interest within the AMI, (ii) any interest in an existing oil and gas lease covering any lands within the AMI, (iii) the
right to acquire any oil and gas lease covering any lands within the AMI or (iv) any mineral interest, fee interest, royalty
interest, overriding royalty interest or other right or interest covering any lands or interests within the AMI), in each case
other than Existing Assets (any such investment, acquisition or participation, a “Restricted Interest”),

undertake any investment in or acquisition of any ownership interest in a Restricted Interest, the Company and Carbon shall each
use their commercially reasonable efforts, including cooperating with one another vis-à-vis the applicable counterparties
involved in the Restricted Interest, to complete the investment in or acquisition of any ownership interest in such Restricted
Interest for the Company’s account on terms acceptable to the Company.

 

(b)       If
(i) the Board elects not to cause the Company to undertake an investment in or acquisition of any ownership interest in a Restricted
Interest or the Board fails to reply to Carbon within the applicable fifteen (15) day period for its response with respect to a
Restricted Interest offered by Carbon to the Company pursuant to Section 3.6(a) and (ii) the Board approves Carbon and its
Affiliates, or its or their respective officers or directors (in their capacities as such), as applicable, to undertake any investment
in or acquisition of any ownership interest in such Restricted Interest, such investment in or acquisition of any ownership
interest in such Restricted Interest (subject to any terms or conditions regarding such investment or acquisition imposed
by the Board) will be deemed a “Permitted Investment”.

 

(c)       Carbon
agrees that neither it nor any of its Affiliates, nor any of its or their respective officers or directors (in their capacities
as such), shall make any investment in, acquire any ownership interest in, or participate in the development of any Restricted
Investment other than (i) Carbon’s investment in the Company, (ii) the Existing Assets and (iii) any Permitted Investments.

 

    22

its Affiliates hold or have an investment or ownership interest in any oil and gas properties, operations or prospects or
any rights and interests therein or relating thereto in the AMI.

no Member shall be entitled to resign or withdraw from the Company.

Member has full power and authority to enter into this Agreement and to perform its obligations hereunder;

has been or will be duly and lawfully acquired and will be contributed to the Company without any liens or encumbrances (other
than statutory liens for taxes not yet due or owing);

 

(d)       such
Member is and will be acquiring its interest in the Company for investment purposes only for his or its own account and not with
a view to the distribution, reoffer, resale, or other disposition not in compliance with the Securities Act and applicable state
securities laws;

Member alone or together with his or its representatives, possesses such expertise, knowledge, and sophistication in financial

Member is aware that he, she or it may have to bear the economic risk of such Member’s investment in the Company for an indefinite
period of time because Interests have not been registered under the Securities Act or under the securities laws of any state, and,
therefore, such Interests cannot be sold unless they are subsequently registered under the Securities Act and any applicable state
securities laws or an exemption from registration is available;

 

(i)       such

(k)       such
Member is an “accredited investor” within the meaning ascribed to such term under Regulation D of the Securities Act;
and

 

(l)       such
Member is not a registered investment company under the Investment Company Act and is not required to register as an investment
company under the Investment Company Act.

Call Notice shall have been delivered pursuant to Section 4.1(c) prior to the Commitment Reduction Date.

 

(h)       Each
Class A Member shall be required to contribute to the Company its Initial Class A Funding Percentage of each Capital Call amount
until the earlier of (i) the Commitment Reduction Date or (ii) an aggregate amount equal to $100,000,000 in cash has been
funded to the Company as Capital Contributions (including the Initial Contributions), subject to Section 4.6 (the earlier
of (i) and (ii), the “Commitment Release Point”).

 

    25

     

    

 

(i)       From
and after the Commitment Release Point, each Class A Member shall be entitled (but not required) to contribute its Class A Sharing
Percentage of each Capital Call amount (as provided in Section 4.1(c)). If any Class A Member (a “Shortfall
Member”) fails to timely contribute its full Class A Sharing Percentage of a Capital Call amount after the Commitment
Release Point and one or more other Class A Members timely contributes its full Class A Sharing Percentage of such Capital Call
amount (the “Non-Shortfall Member”), then the Company or the Non-Shortfall Member shall deliver a written
notice (a “Shortfall Notice”) to the Shortfall Member setting forth the amount such Shortfall Member
failed to timely fund. If the Shortfall Member’s full Class A Sharing Percentage of such Capital Call Amount is not received
by the Company from such Shortfall Member within ten (10) Business Days after delivery of the Shortfall Notice (the “Shortfall
Cure Period”), then the Non-Shortfall Member may, in its discretion, (x) fund all or a portion of the Shortfall Member’s
Unfunded Amount as a Capital Contribution or (y) by delivery of written notice to the Company and the Shortfall Member within twenty
(20) Business Days after the date the Shortfall Notice is delivered to the Shortfall Member, require the Company to return to the
Non-Shortfall Member up to 100% of the amount contributed by the Non-Shortfall Member to the Company in connection with such Capital
Call. A Shortfall Member’s failure to timely fund its Class A Sharing Percentage of any Capital Call after the Commitment
Release Point will result in proportionate dilution of the Class A Sharing Percentage of such Shortfall Member and adjustment of
the Class A Sharing Percentage of each Class A Member to equal an amount, expressed as a percentage, equal to the number of Class
A Units held by such Class A Member divided by the total number of Class A Units held by all Class A Members after giving effect
to such Capital Contribution and the issuance of additional Class A Units in respect of such Capital Contribution. Notwithstanding
anything in this Agreement to the contrary, the proportionate dilution provided for in this Section 4.1(i) and the
option of the Non-Shortfall Member to (x) fund all or a portion of the Shortfall Member’s Unfunded Amount as a Capital Contribution
or (y) receive the return of its funded portion of the applicable Capital Call shall be the sole remedies for the failure of any
Shortfall Member to timely contribute its full Class A Sharing Percentage of any Capital Call after the Commitment Release Point,
and neither the Company nor any Class A Member shall have any other rights or remedies against a Shortfall Member with respect
thereto.

 

(j)       No
Capital Contribution to the Company may be required or permitted from any Person other than in accordance with this Section
4.1 or Section 4.7, and no Person shall be issued or granted any Class A Units or any other Interest by the Company
other than as provided in this Section 4.1 or Section 4.7, in each case without prior approval of the Board pursuant
to Section 2.4(a)(xi).

 

(k)       Exhibit A
shall be amended upon the occurrence of any additional Capital Contributions to reflect such additional Capital Contributions,
the issuance of Class A Units in exchange therefor and the Class A Sharing Percentage of each Class A Member after giving effect
to such additional Capital Contributions.

 

(l)       If
a Capital Call relates to amounts above and below the Commitment Release Point (as determined under clause (ii) of Section 4.1(h)),
such Capital Call shall be treated as two separate Capital Calls, one for the remaining amount required to be funded to achieve
the Commitment Release Point and one for the balance of the amount of such Capital Call.

 

    26

     

    

 

Section 4.2Key
Man Event. Notwithstanding anything herein to the contrary, in the event Patrick R. McDonald no longer serves as Chief Executive
Officer of the Company and/or Mark Pierce no longer serves as President of the Company for any reason (in each case, whether due
to resignation, termination, death, disability or otherwise) (the “Key Man Event”), then:

 

(a)       the
Company shall, as soon as reasonably practicable but in any event within three (3) Business Days following the Key Man Event, deliver
a written notice to the Members informing the Members of the Key Man Event;

 

(b)       if
the Key Man Event involves the loss of the Chief Executive Officer, from and after the Key Man Event, no Class A Member shall be
required to make any additional Capital Contributions to the Company and no Class A Member shall be a Defaulting Member as a result
of failing to fund any additional Capital Contribution due on or after the Key Man Event, provided that any Defaulting Member as
of the Key Man Event shall continue to be a Defaulting Member from and after the Key Man Event; and

 

(c)       if
the Key Man Event involves the loss of the Chief Executive Officer and the President, from and after the Key Man Event, in addition
to the consequences provided in clause (b) above, Old Ironsides may replace Carbon (or cause Carbon to be replaced) as the Manager
and/or cause the Company to effect a Liquidity Event pursuant to Section 6.5.

 

Section 4.3Capital
Accounts.

 

(a)       A
separate Capital Account for each Member shall be established and maintained on the books of the Company in accordance with Treasury
Regulations Section 1.704-1(b)(2)(iv) and, to the extent not in conflict with such Treasury Regulations, the provisions of this
Agreement. Each Member shall have a single Capital Account that reflects all of its Interests, regardless of class or the time
or manner in which acquired. Upon a Transfer of all or part of any Units, the Capital Account, Capital Contributions, and Priority
Amount, if any, of the transferor attributable to the Transferred Units shall carryover to the transferee.

 

(b)       There
will be credited to the Capital Account of each Member (i) the amount of cash and the initial Book Basis of any property contributed
by such Member to the Company, (ii) such Member’s share of Net Income (as determined in accordance with Section 5.1)
and any items of income or gain allocated to such Member pursuant to Section 5.2, and (iii) the amount of any liabilities
of the Company assumed by such Member or that are secured by any property distributed to such Member.

 

(c)       There
will be debited to the Capital Account of each Member (i) the amount of any cash and the Book Basis of any property distributed
by the Company to such Member, (ii) such Member’s share of Net Loss (as determined in accordance with Section 5.1,
and any items of loss or deduction allocated to such Member pursuant to Section 5.2, and (iii) the amount of any liabilities
of such Member assumed by the Company or that are secured by any property contributed by such Member to the Company.

 

(d)       Simulated
Basis shall be allocated among the Members in accordance with each Member’s Capital Interest Percentage as of the time such
Oil and Gas Property is contributed to or acquired by the Company (and any additions to such Simulated Basis resulting from expenditures
required to be capitalized in such Simulated Basis shall be allocated among the Members in a manner designed to cause the Members’
proportionate shares of such Simulated Basis to be in accordance with their Capital Interest Percentages as determined at the time
of any such additions), and shall be reallocated among the Members in accordance with the Members’ Capital Interest Percentages
as determined immediately following the occurrence of an event giving rise to an adjustment to the Book Basis of the Company’s
Oil and Gas Properties pursuant to clause (ii) of the definition of Book Basis.

 

    27

     

    

 

Section 4.4Preemptive
Rights. At any time that the Company proposes to sell Interests to any Person other than Class A Units issued in accordance
with Section 4.1 or Section 4.7, each Member other than a Defaulting Member (each, a “Preemptive
Rights Member”) shall have the preemptive right to purchase its Class A Sharing Percentage share of the Interests.
Any participation pursuant to this Section 4.4 shall be on the same terms and conditions as applied to all offerees in the
respective offering. In the event of a proposed transaction or transactions giving rise to preemptive rights of Preemptive Rights
Members, the Company shall provide notice (“Preemptive Right Notice”) to the Preemptive Rights Members,
which Preemptive Rights Notice shall contain the price at which the Interests will be offered and the other material terms of the
offering and such Interests, no later than ten (10) Business Days prior to the expected consummation of such transaction or transactions.
Each Preemptive Rights Member shall provide notice of its election to exercise its preemptive rights within five (5) Business Days
after delivery of the Preemptive Right Notice from the Company (each Preemptive Rights Member electing to exercise its preemptive
right in such instances is referred to as an “Electing Party”). The failure of a Preemptive Rights Member
to respond to the Preemptive Right Notice and affirmatively exercise its preemptive right in accordance with the terms of this
Agreement shall be deemed as an election of the Preemptive Rights Member not to exercise its preemptive right in connection with
the proposed transaction. If a Preemptive Rights Member shall elect not to exercise its respective preemptive right or fails to
timely exercise, the Electing Parties who timely exercise shall have the right to purchase the Interests (a “Subsequent
Purchase”) as to which no such right was exercised (based on the ratio that the Class A Sharing Percentage of each
Electing Party desiring to purchase the additional Interests bears to the sum of the Class A Sharing Percentages of all Electing
Parties desiring to purchase the additional Interests) insofar as more than one such Electing Party desires to so purchase additional
Interests. In the event of a situation described in the preceding sentence in which a Preemptive Rights Member does not exercise
its preemptive right, the Company shall provide notice (the “Subsequent Notice”) of such fact within
three (3) Business Days following expiration of the deadline for submission of notices concerning such elections from the parties
possessing preemptive rights. Each Electing Party that desires to purchase the additional Interests shall respond to the Subsequent
Notice by sending a response notice with respect thereto within three (3) Business Days after delivery of the Subsequent Notice.
The failure of an Electing Party to respond to a Subsequent Notice and affirmatively exercise its preemptive right in accordance
with the terms of this Agreement shall be deemed an election not to exercise its preemptive right in connection with the Subsequent
Purchase. If the number of Interests proposed to be offered as described in the Preemptive Rights Notice exceeds the sum of the
Interests for which the Preemptive Rights Members timely elected to exercise their preemptive rights (including with respect to
any Subsequent Notice), the Company may offer and issue such excess Interests or any portion thereof (at a price and on other terms
and conditions not more favorable to any proposed offeree or purchaser of such Interests than those set forth in the Preemptive
Rights Notice) to any purchaser of such Interests within one-hundred-twenty (120) days after the date the Preemptive Rights Notice
(or, if applicable, the Subsequent Notice) was delivered. If such issuance is not made within such one-hundred twenty (120) day
period, the Company shall not thereafter issue or sell any of such Interests without first re-offering such securities in the manner
provided above; provided, that if such issuance or sale is subject to regulatory approval, such one-hundred-twenty (120) day period
shall be extended until the expiration of ten (10) Business Days after all such approvals have been received, but in no event later
than one-hundred-eighty (180) days from the date the Preemptive Rights Notice (or, if applicable, the Subsequent Notice) was delivered.

 

    28

     

    

 

Section 4.5Unit
Certificates.

 

(a)       The
Units initially shall be uncertificated, provided that the Board may, in its sole discretion, elect to cause the Company to evidence
ownership of Units by issuing a certificate (each, a “Unit Certificate”) executed by appropriate officers
of the Company certifying the number of Units owned by each Member.

 

(b)       Notwithstanding
anything to the contrary contained in this Agreement, in order to effect a valid Transfer of Units for which a Unit Certificate
has been issued, prior to the effectiveness of such Transfer, the transferring Member, as applicable, shall surrender the subject
Unit Certificate to the Company together with a transfer power duly executed by the transferring Member, as applicable, with the
transferring Member’s signature thereon guaranteed by a medallion stamp upon the Board’s request. Upon such compliance,
surrender and delivery, the Company shall execute and deliver a new Unit Certificate in the name of the assignee(s) and in the
denominations specified in the Transfer documentation, and shall issue to the transferring Member, as applicable, a new Unit Certificate
evidencing the portion of the surrendered Unit Certificate, if any, not so Transferred, and the surrendered Unit Certificate shall
promptly be cancelled.

 

(c)       The
Company shall issue a new Unit Certificate in place of any Unit Certificate theretofore issued by it that is alleged to have been
lost, stolen or destroyed, provided that as a condition precedent thereto the Board may in its discretion require the Member that
is the record owner of any allegedly lost, stolen or destroyed Unit Certificate to deliver to the Company a duly executed affidavit
of loss and an agreement and/or a bond sufficient to indemnify the Company against any adverse claim in connection with the issue
of a new Unit Certificate.

 

(d)       Notwithstanding
anything to the contrary contained in this Agreement, the Board and the Company shall be entitled to rely exclusively on record
ownership of Units for which a Unit Certificate has been issued as evidenced by outstanding Unit Certificates and the Company’s
records thereof. The Company shall treat the record owner of a Unit Certificate as the holder of the Units evidenced thereby unless
and until such Units have been Transferred in accordance with this Agreement.

 

    29

     

    

 

Section 4.6Defaulting
Members. If any Class A Member fails to timely contribute its full Initial Class A Funding Percentage of a Capital Call that
such Class A Member is required to contribute pursuant to Section 4.1(e)(i) and at least one other Class A Member timely
contributes its full Class A Sharing Percentage of such Capital Call amount (the “Non-Defaulting Member”),
then the Company or a Non-Defaulting Member shall deliver a written notice of default (a “Default Notice”)
to the Defaulting Member setting forth the amount such Defaulting Member failed to timely fund. If the Defaulting Member’s
full Initial Class A Funding Percentage of such Capital Call amount is not received by the Company from such Class A Member within
ten (10) Business Days after delivery of the Default Notice (the “Default Cure Period”), then:

 

(i)       such
Class A Member shall be deemed a “Defaulting Member” and

 

if the Defaulting Member
is Carbon, then Supermajority of the Voting Power shall not require the affirmative vote of a Carbon Designee;

 

if the Defaulting Member
is Yorktown, then Supermajority of the Voting Power shall not require the affirmative vote of a Yorktown Designee; and

 

if the Defaulting Member
is Old Ironsides, then a Majority of the Voting Power shall not require the affirmative vote of an Old Ironsides Designee;

 

(ii)       the
Defaulting Member shall not be entitled to participate in any future Capital Calls pursuant to Section 4.1 or as a Preemptive
Rights Member pursuant to Section 4.4;

 

(iii)       each
Non-Defaulting Member shall have the option, exercisable in its sole and absolute discretion to either (A) fund all or a portion
of the Defaulting Member’s Unfunded Amount and to treat such funding of the Unfunded Amount as either an additional Capital
Contribution, subject to Section 4.8 (an “Optional Contribution”), or (B) by delivery of written
notice to the Company and the Defaulting Member within twenty (20) Business Days after the date the Default Notice is delivered
to the Defaulting Member, require the Company to return to the Non-Defaulting Member up to 100% of the amount contributed by the
Non-Defaulting Member to the Company in connection with such Capital Call;

 

(iv)       the
Non-Defaulting Member(s) may fund the Defaulting Member’s Initial Class A Funding Percentage of all subsequent Capital Call
amounts as Optional Contributions until the Defaulting Member’s Capital Commitment has been fully funded; and “Class
A Sharing Percentage” for purposes of Section 4.1(i) and Section 4.4 shall be calculated without giving effect
to Units held by the Defaulting Member; and

 

(v)       if
more than one Non-Defaulting Member elects to fund the Unfunded Amount or the Defaulting Member’s Class A Sharing Percentage
of all subsequent Capital Call amounts, then each Non-Defaulting Member so electing shall be entitled to fund its portion of such
Unfunded Amount or the Defaulting Member’s Class A Sharing Percentage of all subsequent Capital Call amounts based on the
relative Class A Sharing Percentage of each such Non-Defaulting Member, unless otherwise agreed to among such Non-Defaulting Members.

 

    30

     

    

 

Section 4.7Optional
Contribution. If a contribution with respect to an Unfunded Amount is treated as an Optional Contribution pursuant to Section
4.6, upon the receipt of any such Optional Contribution and in consideration of such additional Optional Contribution made
by any Member pursuant to Section 4.1, there shall be issued to such Member a number of Class A Units equal to the quotient
of (x) the amount of such Optional Contribution, divided by (y) the Class A Unit Price, and the Class A Sharing Percentage of each
Class A Member will be adjusted to equal an amount, expressed as a percentage, equal to the number of Class A Units held by such
Class A Member divided by the total number of Units held by all Class A Members after giving effect to such Optional Contribution
and the issuance of additional Class A Units in respect of such Optional Contribution.

 

Section 4.8No
Return of Capital Contributions. Except as expressly provided in this Agreement, a Member shall not be entitled to the return
of any part of its Capital Contributions or to be paid any interest, salary or draw in respect of its Capital Contributions. A
Capital Contribution that has not been repaid is not a liability of the Company or any Member.

 

ARTICLE
V

ALLOCATIONS; DISTRIBUTIONS

 

Section 5.1Allocations
of Net Income or Net Loss. After giving effect to the allocation in Section 5.2 for purposes of maintaining the
Capital Accounts the Company’s items of Net Income and Net Loss shall be allocated among the Members in a manner such that
the Capital Account of each Member, immediately after making such allocations is, as nearly as possible, equal (proportionately)
to the distributions that would be made to such Member pursuant to Section 5.4 if the Company and each of its Subsidiaries
were dissolved, their respective affairs wound up and their respective assets sold for cash equal to their Book Basis, all of the
liabilities of the Company and its Subsidiaries were satisfied (limited with respect to each nonrecourse liability to the Book
Basis of the asset securing such liability), and the net assets of the Company were distributed in accordance with Section 5.4
less (ii) the Member’s share of Company Minimum Gain, share of Member Nonrecourse Debt Minimum Gain, and the amount, if any,
which such Member is obligated to contribute to the capital of the Company.

 

Section 5.2Special
Allocations. Notwithstanding Section 5.1, for each taxable year or other relevant period, the following special
allocations will be made in the following order and priority:

 

(a)       Minimum
Gain Chargeback. If there is a net decrease in Company Minimum Gain for the taxable year or other relevant period, then, to
the extent required by the Treasury Regulations, items of income (determined in accordance with the provisions of Treasury Regulations
Section 1.704-2(f)(6)) shall be specially allocated to the Members in an amount equal to each Member’s share of the net decrease
in Company Minimum Gain (determined in accordance with the provisions of Treasury Regulations Section 1.704-2(g)). This Section 5.2(a)
shall be interpreted consistently with, and subject to the exceptions contained in, Treasury Regulations Section 1.704-2(f).

 

(b)       Member
Minimum Gain Chargeback. If there is a net decrease in Member Nonrecourse Debt Minimum Gain for the taxable year or other relevant
period, then, to the extent required by Treasury Regulations, items of income (determined in accordance with the provisions of
the Treasury Regulations Section 1.704-2(i)(4)) shall be specially allocated to the Members in an amount equal to each Member’s
share of the net decrease in Member Nonrecourse Debt Minimum Gain (determined in accordance with the provisions of Treasury Regulations
Section 1.704-2(i)(5)). This Section 5.2(b) shall be interpreted consistently with, and subject to the exceptions contained
in, Treasury Regulations Section 1.704-2(i)(4).

 

    31

     

    

 

(c)       Qualified
Income Offset. If any Member unexpectedly receives any adjustment, allocation or distribution described in Treasury Regulations
Sections 1.704-1(b)(2)(ii)(d)(4), (5) or (6), which causes or increases such Member’s Adjusted Capital Account Deficit, such
Member will be allocated items of income (including gross income), gain and Simulated Gain in an amount and manner sufficient to
eliminate, to the extent required by the Treasury Regulations, the Member’s Adjusted Capital Account Deficit as quickly as
possible; provided that an allocation pursuant to this Section 5.2(c) shall be made only to the extent that the Member
has an Adjusted Capital Account Deficit after all other allocations provided for in Section 5.1 and this Section 5.2
have been tentatively made as if this Section 5.2(c) was not in this Agreement.

 

(d)       Deficit
Capital Accounts Generally. If any Member has an Adjusted Capital Account Deficit at the end of any Fiscal Year, such member
will be allocated items of income (including gross income), gain and Simulated Gain in an amount and manner sufficient to eliminate
the Member’s Adjusted Capital Account Deficit as quickly as possible; provided that an allocation pursuant to this
Section 5.2(d) shall be made only to the extent that the Member has an Adjusted Capital Account Deficit after all other
allocations provided for in Section 5.1 and this Section 5.2 have been tentatively made as if Section 5.2(c)
and this Section 5.2(d) were not in this Agreement.

 

(e)       Nonrecourse
Deductions. Nonrecourse Deductions shall be allocated among the Members pro rata in accordance with their A/C Sharing
Percentage.

 

(f)       Member
Nonrecourse Deductions. Member Nonrecourse Deductions shall be specially allocated to the Members who bear the economic risk
of loss for the liability to which the deductions are attributable, determined in accordance with the principles of Treasury Regulations
Section 1.704-2(i).

 

(g)       Section
754 Adjustment. To the extent an adjustment to the adjusted tax basis of any Company asset pursuant to Code Sections 734(b)
or 743(b) is required to be taken into account in determining Capital Accounts under Treasury Regulations Section 1.704-1(b)(2)(iv)(m),
the amount of the adjustment shall be included as an item of gain (if positive) or loss (if negative) and shall be specially allocated
to the Members consistent with the manner in which their Capital Accounts are required to be adjusted by such Treasury Regulation.

 

(h)       The
Company’s “excess nonrecourse liabilities” (as defined in Treasury Regulations Section 1.752-3(a)(3)) for a particular
Fiscal Year shall be allocated among the Members pro rata in accordance with their A/C Sharing Percentage

 

(i)       Simulated
Depletion Deductions and Simulated Loss with respect to each Oil and Gas Property shall be allocated in proportion to the manner
in which the Simulated Basis of such property is allocated between the Members pursuant to Section 4.3(d), provided,
however, if the percentage depletion method is used, any excess percentage depletion shall be allocated in accordance with
Treasury Regulations Section 1.704-1(b)(4)(iii). Simulated Gain shall be included in Net Income or Net Loss and allocated pursuant
to Section 5.1.

 

    32

     

    

 

(j)       For
purposes of Treasury Regulations Sections 1.704-1(b)(2)(iv)(k)(2) and 1.704-1(b)(4)(v), the amount realized on the disposition
of any Oil and Gas Property shall be allocated (i) first to the Members in an amount equal to the remaining Simulated Basis of
such property in the same proportions as the Simulated Basis of such property was allocated to the Members pursuant to Section 4.3(d),
and (ii) any remaining amount realized shall be allocated to the Members in the same ratio as the Simulated Gain.

 

Section 5.3Allocations
of Taxable Income or Loss.

 

(a)       Except
as provided in Section 5.3(b), (c), or (d) or as otherwise required by the Code or Treasury Regulations,
solely for U.S. federal income tax purposes, items of Company taxable income, gain, loss and deduction for each Fiscal Year shall
be allocated among the Members in the same manner as each correlative item of income, gain, loss and deduction, as determined for
Capital Account purposes, is allocated pursuant to Section 5.1 and Section 5.2.

 

(b)       If
property contributed to the Company by a Member has an adjusted U.S. federal income tax basis that differs from its initial Book
Basis on the date of contribution or if the Book Basis of property is adjusted upon the occurrence of a Revaluation Event, income,
gain, loss and deductions with respect to such property will, solely for tax purposes, be allocated among the Members so as to
take account of such difference. Such allocations will be made among the Members in the manner provided in Section 704(c) of the
Code, pursuant to the remedial allocation method described in Treasury Regulations Section 1.704-3(d), or such other reasonable
method determined by the Board of Directors.

 

(c)       Depreciation,
depletion, intangible drilling cost, and amortization recapture amounts under Sections 1245, 1250 or 1254 of the Code and the Treasury
Regulations thereunder, if any, resulting from any sale or disposition of tangible or intangible depreciable, depletable or amortizable
property shall be allocated to the Members in the same proportions that the depreciation, depletion, intangible drilling cost or
amortization being recaptured was allocated.

 

    33

     

    

 

(d)       Pursuant
to Section 613A(c)(7)(D) of the Code and the Treasury Regulations promulgated thereunder, cost and percentage depletion deductions
with respect to any Oil and Gas Property shall be computed separately by the Members rather than the Company. For purposes of such
computations, the U.S. federal income tax basis of each Oil and Gas Property shall be allocated to each Member in accordance with
such Member’s Capital Interest Percentage as of the time such Oil and Gas Property is contributed to or acquired by the Company
(and any additions to such U.S. federal income tax basis resulting from expenditures required to be capitalized in such basis shall
be allocated among the Members in a manner designed to cause the Members’ proportionate shares of such adjusted U.S. federal
income tax basis to be in accordance with their respective Capital Interest Percentages as determined at the time of any such additions),
and shall be reallocated among the Members in accordance with the Members’ respective Capital Interest Percentages as determined
immediately following the occurrence of an event giving rise to an adjustment to the Book Basis of the Company’s Oil and
Gas Properties pursuant to clause (ii) of the definition of Book Basis. The Company shall include in the information provided to
each Member pursuant to this Agreement such Member’s allocable share of the U.S. federal income tax basis of each Oil and
Gas Property, any adjustment resulting from expenditures required to be capitalized in such basis, and any reallocation of such
basis as provided in the previous sentence. The allocations described in this Section 5.3 are intended to be applied in
accordance with the Members’ “interests in partnership capital” under Section 613A(c)(7)(D) of the Code; provided
that the Members may, in good faith, authorize special allocations of U.S. federal income tax basis, income, gain, deduction or
loss, as computed for U.S. federal income tax purposes, in order to eliminate differences between Simulated Basis and adjusted
U.S. federal income tax basis with respect to Oil and Gas Properties, in such manner as determined consistent with the principles
outlined in Section 5.3(b). The provisions of this Section 5.3 and the other provisions of this Agreement relating
to allocations under Section 613A(c)(7)(D) of the Code are intended to comply with Treasury Regulations Section 1.704–1(b)(4)(v)
and shall be interpreted and applied in a manner consistent with such Treasury Regulations. Each Member, with the assistance of
the Company, shall separately keep records of its share of the adjusted tax basis in each Oil and Gas Property, adjust such share
of the adjusted tax basis for any cost or percentage depletion allowable with respect to such property and use such adjusted tax
basis in the computation of its cost depletion or in the computation of its gain or loss on the disposition of such property by
the Company. Upon the request of the Company, each Member shall advise the Company of its adjusted tax basis in each Oil and Gas
Property and any depletion computed with respect thereto, both as computed in accordance with the provisions of this subsection.
The Company may rely on such information and, if it is not provided by the Member, may make such reasonable assumptions as it shall
determine with respect thereto. The Company shall provide each Member with information reasonably requested by such Member to comply
with this Section 5.3 and other tax reporting obligations.

 

Section 5.4Distributions.
Distributions from the Company will be made from Available Cash or pursuant to Section 5.4(d), as provided in this
Section 5.4:

 

(a)       Distributions
of Available Cash and pursuant to Section 5.4(d) shall be made upon the occurrence of any of a Liquidity Event or as
otherwise determined by the Board from time to time, and all such distributions shall be allocated and distributed as follows:

 

(i)       first,
until the Priority Amount of each Class A Unit has been reduced to zero, (A) an amount equal to the A/C Sharing Percentage of the
holder of Class C Units shall be allocated and distributed to the holder of Class C Units and (B) the remaining amount shall be
allocated to the holders of Class A Units and distributed to each such holder of Class A Units in proportion to the respective
aggregate Priority Amount of the Class A Units held by such holders of Class A Units;

 

(ii)       thereafter
(subject to the following paragraph), (A) eighty percent (80%) shall be allocated among the holders of Class A Units and the holder
of Class C Units in proportion to their respective A/C Sharing Percentages at such time and (x) such amount allocated to the holders
of Class A Units shall be distributed to the holders of Class A Units in proportion to their respective Class A Sharing Percentage
at such time and (y) such amount allocated to the holder of Class C Units shall be distributed to such holder of Class C Units
and (B) twenty percent (20%) shall be allocated and distributed to the holder of Class B Units.

 

    34

     

    

 

If, after any distributions
are made pursuant to this Section 5.4, additional Capital Contributions are made on account of or in exchange for Class
A Units, then (x) subsequent distributions under this Section 5.4 shall be made giving effect to such additional Capital
Contributions and the effect of such additional Capital Contributions on the distributions to be made pursuant to Section 5.4
to each holder of Class A Units and the amount required to be distributed to each holder of Class A Units pursuant to each of Section
5.4(a)(i) and (ii), and (y) any amount that otherwise would be distributable to the holders of Class B Units on account
of their Class B Units shall instead be paid to the holders of Class A Units on account of their Class A Units until the holders
of Class A Units shall have received on account of their Class A Units the amount that they would have received on account of their
Class A Units pursuant to this Agreement based on the total amount that has been distributed by the Company.

 

(b)       All
distributions, including tax distributions treated as advances of such distributions pursuant to Section 5.4, shall
be credited towards or applied against the return calculations in clause (a) above. For the avoidance of doubt, no distributions
will be made under this Agreement other than distributions made pursuant to this Section 5.4 and Section 5.5.
In the event that a reassignment to Nytis LLC occurs pursuant to Section 2.4 of the Participation Agreement, such reassignment
amounts shall not be treated as a distribution under this Agreement.

 

(c)       Prior
to the dissolution of the Company in accordance with Article VII, distributions pursuant to Section 5.4
may only be made of cash and Marketable Securities without the approval of a Supermajority of the Voting Power. In connection with
a dissolution of the Company in accordance with Article VII, the Company may distribute property other than cash and
Marketable Securities with the approval of a Majority of the Voting Power.

 

(d)       Cash
and Non-Cash Distributions.

 

(i)       Subject
to Section 5.4(d)(ii), if any distribution consists of both cash and non–cash property, then unless otherwise
determined by a Supermajority of Voting Power the cash and non–cash property shall be distributed on a pro rata basis such
that the total amount of property distributed on account of each Unit shall contain the same percentage of cash and the same percentage
of non–cash property (based on the Fair Market Value of such non–cash property), and, to the extent the non–cash
distributable property shall consist of more than one item of non–cash property, the Board shall, to the extent practicable,
allocate to each Unit receiving a distribution the same percentage (as a percentage of the total value of cash and non–cash
property distributed) of each item or type of non–cash property.

 

    35

     

    

 

(ii)       If
any distribution consists of both cash and non–cash property and such distribution is allocated among more than one class
of Units, then the cash and non–cash property shall be distributed on a pro rata basis such that the total amount of property
distributed to each class of Units receiving a distribution shall contain the same percentage of cash and the same percentage of
non–cash property (based on the Fair Market Value of such non–cash property), and, to the extent the non–cash
distributable property shall consist of more than one item of non–cash property, the Board shall, to the extent practicable,
allocate to each class of Units receiving a distribution the same percentage (as a percentage of the total value of cash and non–cash
property distributed) of each item or type of non–cash property.

 

(iii)       The
amount of any non-cash property to be distributed in accordance with Section 5.4 shall be its Fair Market Value.

 

(e)       Any
distributions pursuant to this Section 5.4 made in error or in violation of Section 18-607(a) of the Act, will, upon
demand by the Board, be returned to the Company.

 

Section 5.5Tax
Distributions. Subject to the Act, the Company may, to the extent of Available Cash and in proportion to their respective allocations
of taxable income of the Company for the taxable year, distribute to the Members an amount up to the aggregate amount equal to
the Tax Liability Deficiency. The distributions pursuant to this Section 5.5 shall be made in quarterly installments on
an estimated basis on or before the 10th day of each March, June, September and December. The amount to be distributed to a Member
pursuant to this Section 5.5 in respect of any taxable year shall be computed as if any distributions made to such Member
pursuant to Section 5.4 during such taxable year were a distribution under this Section 5.5 in respect of such taxable
year.

 

(a)       All
distributions made to a Member pursuant to this Section 5.5 on account of the taxable income allocated to such Member shall
be treated as advance distributions under Section 5.4 and shall be taken into account in determining the amount of
future distributions to such Member, and for purposes of determining the amount of distributions to be made to the Members pursuant
to Section 5.4, distributions made pursuant to this Section 5.5 shall be taken into account at such time as
they are being made pursuant to this Section 5.4.

 

Section 5.6Liability
of Members; Return of Class A Distributions and Class C Distributions.

 

(a)       Except
as explicitly provided in the Act, no Member shall be liable for any debts, liabilities, contracts or obligations of the Company
whatsoever.

 

(b)       (i)
Except as required by the Act, other applicable law or as otherwise expressly set forth herein, no Member shall be required to
repay to the Company, any Member or any creditor of the Company all or any part of the distributions made to such Member pursuant
hereto; provided, however, that, subject to the limitations set forth in Section 5.6(c) hereof, the Board may
require a Class A Member and a Class C Member to return distributions made to such Class A Member on account of their Class A Units
and Class C Member on account of its Class C Units for the purpose of meeting such Member’s pro rata share of any Company
Expenses (as determined by the Board based on distributions received from the Company by each Class A Member on account of its
Class A Units and Class C Member on account of its Class C Units relative to all distributions received from the Company by all
Class A Members on account of their Class A Units and Class C Member on account of its Class C Units); provided, however,
that in no event shall the Board require any Class A Member or Class C Member to return any distributions unless the Board requires
each Class A Member and the Class C Member to return a proportionate share (as determined on the same basis as above) of distributions.

 

    36

     

    

 

(ii)       If,
notwithstanding anything to the contrary contained herein, it is determined under applicable law that any Class A Member or Class
C Member has received a distribution which is required to be returned to or for the account of the Company or Company creditors,
then the obligation under applicable law of any Class A Member or Class C Member to return all or any part of a distribution made
to such Class A Member or Class C Member shall be the obligation of such Class A Member or Class C Member and not of any other
Class A Member or Class C Member.

 

(iii)       Any
amount returned by a Class A Member or Class C Member pursuant to this Section 5.6(b) shall be treated as a Capital Contribution
to the Company.

 

(c)       The
obligation of a Class A Member and a Class C Member to return distributions pursuant to this Section 5.6 shall survive the
termination of the Company and this Agreement and be subject to the following limitations:

 

(i)       no
Class A Member or Class C Member shall be required to return a distribution after the earlier to occur of (x) the third anniversary
of the date of termination of the Company, and (y) the third anniversary of the date of the applicable distribution; provided,
however, that if at such applicable anniversary, there are any legal proceedings then pending or any other liability (whether
contingent or otherwise) or claim then outstanding, then, the obligation of such Class A Member or Class C Member to return such
distribution for the purpose of meeting such Member’s pro rata share of any Company Expenses shall survive with respect to
each such legal proceeding, liability and claim set forth in such notice (or any related legal proceeding, liability or claim based
upon the same or a similar claim) until the date that such legal proceeding, liability or claim is ultimately resolved and satisfied;

 

(ii)       the
aggregate amount of distributions which a Class A Member or Class C Member may be required to return hereunder shall not exceed
an amount equal to the aggregate amount of distributions made to them on account of their Class A Units or Class C Units, as applicable
(net of taxes actually paid on account of such distributions by any such holder of Class A Units or Class C Units, its Affiliates
or direct or indirect members or equity owners).

 

Section 5.7Return
of Class B Distributions. If, upon the dissolution by the Company pursuant to Article VII and the final distribution
of all assets of the Company pursuant to Section 5.4, the amount distributed on account of the Class B Units exceeds
the aggregate amount distributable on account of the Class B Units pursuant to Section 5.4 after giving effect to all distributions
pursuant to Section 5.4 and Section 5.5 (the amount of such excess, the “Excess Class B Distribution
Amount”) then the Class B Member shall return to the Company an amount equal to the Excess Class B Distribution Amount,
and the amount returned to the Company shall be allocated among and distributed to the holders of Class A Units and Class C Units
in accordance with Section 5.4 and Section 5.5, as applicable.

Section 6.1Transfers.

 

(a)       No
Transfer of all or part of a Member’s Interest may be made except (i) in the case of Yorktown or Carbon, with the approval
of a Majority of the Voting Power (provided that approval of a Majority of the Voting Power is not required for a Yorktown-Carbon
Assignment), (ii) to a Permitted Transferee of such Member, (iii) in accordance with Section 6.2, Section 6.3,
Section 6.5, Section 6.6 or Section 6.9, or (iv) Transfers to or from a Subject Company pursuant
to Section 6.4, and then only if a counterpart of the instrument of Transfer, executed and acknowledged by or on behalf
of the parties thereto (provided if a holder of Units fails to execute any such instrument in breach of its obligations under this
Agreement, the signature of such Person shall not be required) is delivered to the Company. Notwithstanding the foregoing, no Indirect
Parent Transfer may be made without first obtaining approval of a Supermajority of the Voting Power. A permitted Transfer will
be effective as of the date specified in the instruments of assignment or conveyance, subject to applicable law, provided that
an assignee will not be admitted as a Member except in accordance with Section 6.7. Notwithstanding the foregoing, the Class
B Units and Class C Units shall not be Transferable except as expressly provided in this Article VI.

 

(b)       In
no event shall a Transfer be permitted if (i) such Transfer would cause interests in the Company to be traded on an established
securities market, secondary market or substantial equivalent thereof within the meaning of Treasury Regulations Sections 1.7704-1
or (ii) such Transfer would cause the Company to become subject to regulation under either the Investment Company Act or the Investment
Advisers Act.

 

Section 6.2Drag-Along
Rights.

 

(a)       In
the event Old Ironsides or its Permitted Transferees propose to Transfer all or any portion of its Interests other than to a Permitted
Transferee of such Member and such Interests constitute more than 50% of the outstanding Class A Units (a “Drag-Along
Sale”), Old Ironsides and its Permitted Transferees effecting such Transfer (collectively, the “Dragging
Member”) shall have the right to require each other Member (each, a “Drag-Along Member”)
to sell their Interests in such Drag-Along Sale by Transferring up to a proportion (based on the percentage of the Class A Units
being Transferred by the Dragging Member relative to the number of Class A Units owned by the Dragging Member) of the Class A Units
held by each Drag-Along Member at the purchase price and upon the other terms and subject to the conditions of the Drag-Along Sale
(all of which shall be set forth in the Drag-Along Notice).

 

(b)       The
Dragging Member shall provide each Drag-Along Member written notice of the terms and conditions of such proposed Transfer (the
“Drag-Along Notice”) not later than 15 Business Days prior to the closing of the proposed Drag-Along
Sale. The Drag-Along Notice shall contain a true and complete copy of any and all available documents constituting the agreement
to transfer and, to the extent not set forth in the accompanying documents, the price offered for the Interests, all information
reasonably available to the Dragging Member regarding the acquirer, all other material terms and conditions of the proposed Drag-Along
Sale and, in the case of a proposed Drag-Along Sale in which the consideration payable for the Interests consists in whole or in
part of consideration other than cash, such information relating to such other consideration as is reasonably available to the
Dragging Member. Each Drag-Along Member shall be required to participate in the Drag-Along Sale on the terms and conditions set
forth in the Drag-Along Notice and this Section 6.2. No Member shall have any dissenters’ or appraisal rights in connection
with the Drag-Along Sale, and each Member hereby releases, and will execute such further instrument as the Company reasonably requests
to further evidence the waiver of, such rights.

 

    38

     

    

 

(c)       Within
10 Business Days following receipt of the Drag-Along Notice (the “Drag-Along Notice Period”), each
Drag-Along Member must deliver to such Dragging Member (i) wire transfer instructions for payment of the purchase price for the
Interests to be sold in such Drag-Along Sale, and (ii) all other documents required to be executed in connection with such Drag-Along
Sale. Each Member makes, constitutes, and appoints the Manager (or its chief executive officer, in his official corporate capacity)
as its true and lawful attorney-in-fact for such person and in its name, place, and stead and for its use and benefit, to sign,
execute, certify, acknowledge, swear to, file, and record any instrument that is now or may hereafter be deemed necessary by the
Company in its reasonable discretion to carry out fully the provisions and the agreement, obligations, and covenants of such Member
in this Section 6.2 in the event that such Member is or becomes a Drag-Along Member pursuant to this Section 6.2.
Each Member hereby gives such attorney-in-fact full power and authority to do and perform each and every act or thing whatsoever
requisite or advisable to be done in connection with such Member’s obligations and agreements as a Drag-Along Member pursuant
to this Section 6.2 as fully as such Member might or could do personally, and hereby ratifies and confirms all that any
such attorney-in-fact shall lawfully do or cause to be done by virtue of the power of attorney granted hereby. The power of attorney
granted pursuant hereto is a special power of attorney, coupled with an interest, and is irrevocable, and shall survive the bankruptcy,
insolvency, dissolution or cessation of existence of the applicable Member.

 

(d)       If,
at the end of the 90-day period after the date on which the Dragging Member gives the Drag-Along Notice (which 90-day period shall
be extended if any of the transactions contemplated by the Drag-Along Sale are subject to regulatory approval until the expiration
of five Business Days after all such approvals have been received, but in no event later than 120 days following the delivery of
the Drag-Along Notice), the Drag-Along Sale has not been completed on substantially the same terms and conditions set forth in
the Drag-Along Notice, the Drag-Along Members shall no longer be obligated to sell their Interests pursuant to such Drag-Along
Notice and the Dragging Member shall return to each Drag-Along Member any documents in the possession of the Dragging Member executed
by or on behalf of such Drag-Along Member in connection with the proposed Drag-Along Sale.

 

(e)       Concurrently
with the consummation of the Drag-Along Sale, Dragging Member shall (i) notify the Drag-Along Members thereof, (ii) remit to the
Drag-Along Members the total consideration for the Interests of the Drag-Along Members Transferred pursuant thereto, and (iii)
promptly after the consummation of the Drag-Along Sale, furnish such other evidence of the completion and the date of completion
of such Transfer and the terms thereof as may be reasonably requested by the Drag-Along Members.

 

    39

     

    

 

(f)       Notwithstanding
anything contained in this Section 6.2, there shall be no liability on the part of the Dragging Member to the Drag-Along
Members if the Transfer of the Interests pursuant to this Section 6.2 is not consummated for whatever reason.

 

(g)       Notwithstanding
anything contained in this Section 6.2, the obligations of the Drag-Along Members to participate in a Drag-Along Sale
are subject to the following conditions:

 

(i)       upon
consummation of such Drag-Along Sale, (A) all of the Members participating therein will receive the same form of consideration,
and (B) the aggregate consideration received by the Members will be paid to the Members subject to the allocation provisions set
forth in Section 5.4;

 

(ii)       no
Drag-Along Member participating therein shall be obligated to pay any expenses incurred in connection with any unconsummated Drag-Along
Sale, and each Drag-Along Member shall be obligated to pay only its pro rata share (based on the amount of the purchase price received)
of expenses incurred in connection with a consummated Drag-Along Sale to the extent such expenses are incurred for the benefit
of all Members and are not otherwise paid by the Company or another person;

 

(iii)       without
the written consent of a Drag-Along Member, such Drag-Along Member shall not be obligated with respect to (A) any representation
or warranty other than (I) a representation and warranty that relates solely to such Drag-Along Member’s title to its
Interest, and its authority and capacity to execute and deliver the subject purchase and sale agreement or (II) a representation
and warranty that relates to the Company and its operations which each Member is severally making to the buyer, or (B) any indemnity
obligation beyond a pro rata portion (based on and limited to the value of consideration received by such Drag-Along Member in
the Drag-Along Sale) of the indemnity obligations which obligate the Dragging Member and all Drag-Along Members and then, such
indemnity obligations shall be several and not joint, or (C) any other continuing obligation on such Drag-Along Member in favor
of any other person following the Disposition of such Drag-Along Member’s Interests (other than obligations relating to representations
and warranties that relate solely to such Drag-Along Member and not to any other Member or the indemnification obligation provided
for in clause (B) above);

 

(iv)       no
Drag-Along Member shall be obligated to consummate such Drag-Along Sale contemplated by the Drag-Along Notice with respect to its
Interests unless the Dragging Member consummates such Drag-Along Sale with respect to all (but not less than all) of their
Interests on the terms and conditions contemplated by the Drag-Along Notice; and

 

(v)       no
Drag-Along Member shall be obligated to participate in a Drag-Along Sale that is an Excluded Affiliate Transfer.

 

    40

     

    

 

(h)       If
a Member whose Class A Units are Transferred pursuant to this Section 6.2 also holds Class B Units or Class C Units
and all of such Member’s Class A Units are Transferred pursuant to this Section 6.2, then all Class B Units and all
Class C Units held by such Member shall be Transferred together with such Member’s Class A Units in the Drag-Along Sale.
If a Member whose Class A Units are Transferred pursuant to this Section 6.2 also holds Class B Units or Class C Units
and less than all of such Member’s Class A Units are Transferred pursuant to this Section 6.2, then all Class B Units
and all Class C Units held by such Member shall be retained by such Member and not included in the Drag-Along Sale.

 

(i)       In
any Drag-Along Sale in which a Drag-Along Member participates pursuant to this Section 6.2, the aggregate consideration
to be paid by the acquiring party shall be allocated among each class of Units included in such Drag-Along Sale and the holders
of Class A Units (with respect to their Class A Units), the holders of Class B Units (with respect to their Class B Units) and
the holder of Class C Units (with respect to the Class C Units) included in the Drag-Along Sale as provided in Section 6.11.

 

Section 6.3Tag-Along
Rights.

 

(a)       In
the event Old Ironsides or its Permitted Transferees propose to Transfer any of its Interests other than to a Permitted Transferee
of such Member and such Interests constitute more than 50% of the outstanding Class A Units, then Old Ironsides and its Permitted
Transferees effecting such Transfer (collectively, the “Tag-Along Transferring Member”) shall permit
Yorktown and Carbon (each, a “Tag-Along Participant”) to participate in such Transfer (a “Tag-Along
Sale”) by Transferring (at each Tag-Along Participant’s election) up to a proportion (based on the percentage
of the Class A Units being Transferred by the Tag-Along Transferring Member relative to the number of Class A Units owned by the
Tag-Along Transferring Member) of the Class A Units held by each Tag-Along Participant at the purchase price and upon the other
terms and subject to the conditions of the Tag-Along Sale (all of which shall be set forth in the Tag-Along Notice).

 

(b)       At
least twenty (20) Business Days prior to the date on which the Tag-Along Transferring Member expects to consummate the Transfer,
the Tag-Along Transferring Member shall deliver a written notice (“Tag-Along Notice”) to the Tag-Along
Participants, which shall set forth all relevant information with respect to the proposed Transfer, including the identity of the
buyer, the proposed purchase price, the Interests that are the subject of the sale, the expected closing date of the Transfer,
and any other terms and conditions of the proposed Transfer (including copies of all available and relevant proposed purchase and
sale documents). Any Tag-Along Participant electing to participate in the Transfer shall provide the Tag-Along Transferring Member
with written notice thereof within ten (10) Business Days prior to the date on which the Tag-Along Transferring Member expects
to consummate the Transfer (or if the Tag-Along Transferring Member delivers an amended Tag-Along Notice, within 10 days after
the delivery of such amended Tag-Along Notice (and the closing of the Transfer shall not occur prior to the expiration of 10 days
after such amended Tag-Along Notice has been delivered to each Tag-Along Participant)). Each Tag-Along Participant electing to
Transfer its Interests shall execute such documents, as are executed by the Tag-Along Transferring Member with respect to the Transfer;
provided, however, that any representations and warranties relating specifically to any Member shall only be made by that
Member and any indemnification provided by the Members shall be made on a several, not joint, basis (provided each Tag-Along Transferring
Member and Tag-Along Participant shall be required to provide proportionate (based on the amount of consideration to be received)
indemnification with respect to any representations and warranties related to the Company and its Subsidiaries); provided further,
however, that each Tag-Along Participant shall be required to represent and warrant with respect to the Required Representations.
In no event shall the amount of any indemnity obligation of any Tag-Along Participant exceed the amount of cash and the Fair Market
Value of any non-cash consideration received by such Tag-Along Participant in such Transfer, except in the case of fraud by such
Tag-Along Participant. Any indemnification or other obligation assumed or incurred in connection with a Transfer shall be allocated
among the Persons Transferring Units in connection with such Transfer in the same proportion as the consideration received by such
Persons in connection with such Transfer, in each case other than with respect to the Required Representations.

 

    41

     

    

 

(c)       After
the consummation of the Transfer pursuant to this Section 6.3, the Tag-Along Transferring Member shall give notice thereof
to the Tag-Along Participants, shall remit to each such Tag-Along Participant any funds due to such Tag-Along Participant and held
by the Tag-Along Transferring Member, and shall furnish such other evidence of the completion of such Transfer and the terms thereof
as may be reasonably requested by such Tag-Along Participant. If within ninety (90) days after the Tag-Along Transferring Member
gives the Tag-Along Notice (or the amended Tag-Along Notice, if applicable), which 90-day period shall be extended if any of the
transactions contemplated by the Tag-Along Sale are subject to regulatory approval until the expiration of five Business Days after
all such approvals have been received, but in no event later than 120 days following the delivery of the Tag-Along Notice (or the
amended Tag-Along Notice, if applicable), the Tag-Along Transferring Member has not completed the Transfer, it shall return to
each Tag-Along Participant any documents in possession of the Tag-Along Transferring Member executed by such Tag-Along Participant
in connection with such proposed Transfer.

 

(d)       Each
Member selling any Units pursuant to any Transfer pursuant to this Section 6.3 in which less than all of the outstanding
Class A Units are sold (a “Tag-Along Partial Sale”) shall, prior to the consummation of such sale, notify
the Board of which Class A Units are being sold by such Member (including any Capital Contributions and distributions previously
made in respect of such Class A Units) pursuant to such Tag-Along Partial Sale. The transferee of such Class A Units shall succeed
to the portion of the Capital Account and characteristics associated with such Class A Units.

 

(e)       If
a Tag-Along Participant also holds Class B Units or Class C Units and such Tag Along Participant is disposing of all of its Class
A Units in such Tag-Along Sale, then all Class B Units and all Class C Units held by such Tag-Along Participant shall be Transferred
in such Tag-Along Sale together with such Tag-Along Participant’s Class A Units. If a Tag-Along Participant also holds Class
B Units or Class C Units and such Tag Along Participant is disposing of less than all of its Class A Units in such Tag-Along Sale,
then all Class B Units and all Class C Units held by such Tag-Along Participant shall be retained by such Member and not included
in such Tag-Along Sale.

 

    42

     

    

 

(f)       In
any Tag-Along Sale in which a Tag-Along Participant participates pursuant to this Section 6.3, the aggregate consideration
to be paid by the acquiring party shall be allocated among each class of Units included in such Tag-Along Sale and among the holders
of Class A Units (with respect to their Class A Units), the holders of Class B Units (with respect to their Class B Units) and
the holder of Class C Units (with respect to the Class C Units) included in such Tag-Along Sale as provided in Section 6.11.

 

(g)       For
purposes of this Section 6.3, “Old Ironsides” shall mean Old Ironsides and each transferee of Class A Units
from Old Ironsides and “Carbon” shall mean Carbon and each transferee of Class A Units from Carbon.

 

Section 6.4Indirect
Transfer.

 

(a)       If
any holder of Class A Units or any Parent of a holder of Class A Units proposes to effect a transaction or series of transactions
that would result in a Change in Control of such holder of Class A Units or any such Parent (such transaction, an “Indirect
Parent Transfer”), then such holder of Class A Units (the “Subject Company”) or its Parent
shall give written notice to the other Class A Members (“IPT Notice”) at least twenty (20) days prior
to the consummation of such Indirect Parent Transfer (or such shorter period as is agreed by the relevant parties), stating the
desire of such holder of Class A Units or such Parent to effect such Indirect Parent Transfer, the identity of the other party
to such transaction (the “Offeror”), the interest to be Transferred, and all other material terms and
conditions of such transaction, including a description of purchase price allocation.

 

(b)       Upon
an Indirect Parent Transfer consummated without the approval of the IPT Eligible Member, (i) each IPT Eligible Member shall have
the right to, each at its own option, purchase all, but not less than all, of the Units held by the Subject Company for an amount
in cash equal to the implied value per Unit allocated to such Units by the Offeror, or if no such allocation is made by the Offeror,
the fair market value of such Units (such implied value or fair market value per Unit the “IPT Transaction Value”)
(provided more than one IPT Eligible Member exercises its right to purchase, each exercising IPT Eligible Member will have the
right to purchase its pro rata portion of the Units being sold in the proportion that the relative Class A Sharing Percentage of
the exercising Members) or (ii) if the IPT Eligible Member does not exercise its rights under clause (i) above, then each IPT Eligible
Member, each at its own option, may sell to the Subject Company, and the Subject Company shall have the obligation to purchase,
all, but not less than all, of the Units held by each exercising IPT Eligible Member for an amount in cash equal to the IPT Transaction
Value of such Units. Such rights may be exercised by written notice to the Subject Company given within twenty (20) days of receipt
of the IPT Notice, or, if an IPT Notice is not delivered to a IPT Eligible Member in violation of this Section 6.4(b)
or an Indirect Parent Transfer otherwise occurs with respect to a IPT Eligible Member, then such right may be exercised by the
applicable IPT Eligible Member(s) providing written notice to the Subject Company within one hundred twenty (120) days after such
IPT Eligible Member obtains actual knowledge of such Indirect Parent Transfer (any such notice, and “IPT Exercise Notice”).
The failure of a recipient of an IPT Notice or any other IPT Eligible Member to notify the Subject Company within such applicable
time period provided above of any election under this Section 6.4(b) shall be deemed an election by such IPT Eligible
Member not to exercise its right to acquire or sell Units pursuant to this Section 6.4 in connection with such Indirect
Parent Transfer.

 

    43

     

    

 

(c)       For
purposes of this Section 6.4, the “fair market value” of any Units shall be the fair market value
of such Units, as agreed to by the Subject Company and the holders of each Class of Units electing to purchase or sell such Units
(such holders electing to purchase or sell Units, collectively as to each class of Units, the “Exercising Member”)
that collectively hold a majority of such class of Units held by all Exercising Members of such class of Units (as to each class
of Units, the “Primary Exercising Members”) or, in the event the Subject Company and the Primary Exercising
Member fail to agree within fifteen (15) days after the Exercising Member has delivered a IPT Exercise Notice to the Subject Company
in accordance with Section 6.4(b), the fair market value of such Units as determined by a Qualified Appraiser which
has not had any material engagement with the Subject Company or the Primary Exercising Members or any of their respective Affiliates
in the preceding two years selected by the Primary Exercising Member. Any such Qualified Appraiser so appointed shall be deemed
the “Initial Appraiser.”

 

(d)       In
the event that the Subject Company objects to the fair market value determination made by the Initial Appraiser, then the Subject
Company may, within thirty (30) days after receipt of the Initial Appraiser’s determination of fair market value, select
a Qualified Appraiser which has not had any material engagement with the Subject Company or the Primary Exercising Member or any
of their respective Affiliates in the preceding two years (the “Second Appraiser”). The Initial Appraiser
and the Second Appraiser shall thereupon select a third Qualified Appraiser (the “Neutral Appraiser”).
The Subject Company and the Exercising Member shall execute such engagement and indemnity agreements as the Neutral Appraiser shall
require as a condition to engagement and each shall be responsible for all fees and expenses of the investment bank selected by
it and for its one–half of all fees and expenses of the Neutral Appraiser. The Subject Company and the Exercising Member
shall, and shall cause their respective Affiliates to, make available to the other and the investment banks such information as
is reasonably necessary to reach a fair market value determination. Each of the Initial Appraiser, Second Appraiser, and Neutral
Appraiser shall independently determine its proposed fair market value of the Units, and “fair market value”
shall thereupon mean the average of the two such proposed fair market values that are nearest to one another. The following principle
shall apply generally to any determination of fair market value under this Section 6.4: fair market value shall mean the
cash price at which the Units would change hands between a willing buyer and a willing seller, neither being under any compulsion
and both having a reasonable knowledge of the relevant facts including the application of Section 5.4 and without reduction
based upon any lack of control, minority ownership, marketability or other similar discounts. If the Subject Company fails to select
the Second Appraiser within the 30 day period provided above, such Subject Company shall be deemed to have waived such objection
and the fair market determination by the Initial Appraiser shall be deemed final.

 

(e)       Notwithstanding
anything in this Section 6.4, within fifteen (15) days after receipt of an IPT Exercise Notice by a Subject Company such
Subject Company may deliver written notice (a “Cure Notice”) to the Person who delivered such IPT Exercise
Notice that the Indirect Parent Transfer was inadvertent and such Subject Company may, during the thirty (30) days immediately
following delivery of a Cure Notice (the “Cure Period”), effect such actions to cause the Change in Control
giving rise to the Indirect Parent Transfer to cease to exist such that there shall no longer exist a Change in Control of such
Subject Company, and the time periods for actions to occur after delivery of an IPT Exercise Notice (other than the Cure Period)
shall be tolled during such Cure Period. If the Subject Company successfully takes such action within such Cure Period to cause
the Change in Control giving rise to such Indirect Parent Transfer to cease to exist such that there shall no longer exist a Change
in Control of the Subject Company upon the expiration of such Cure Period, then this Section 6.4 shall no longer apply with
respect to such previous Indirect Parent Transfer.

(f)       Notwithstanding
anything in this Section 6.4, a Change in Control of the Ultimate Parent of Old Ironsides shall not constitute a Change
in Control of Old Ironsides or any Permitted Transferee of Old Ironsides, a Change in Control of the Ultimate Parent of Yorktown
shall not constitute a Change in Control of Yorktown or any Permitted Transferee of Yorktown, a Change in Control of the Ultimate
Parent of Carbon shall not constitute a Change in Control of Carbon or any Permitted Transferee of Carbon, and a Change in Control
of the Ultimate Parent of any other Member shall not constitute a Change in Control of such Member or any Permitted Transferee
of such Member for purposes of this Section 6.4.

 

Section 6.5Liquidity
Event.

 

(a)       Notwithstanding
anything to the contrary set forth herein:

 

(i)       So
long as the Company has not effected a Public Offering, at any time following the seventh anniversary of the Effective Date, Yorktown
and Old Ironsides shall each have the right, at each of their express direction and in each of their sole discretion, to direct
the Board to take such actions to effect a Liquidity Event upon delivering a written notice thereof to the Board of such direction
(a “Liquidity Event Notice”).

 

(ii)       (A)
At any time Yorktown or Carbon is a Defaulting Member, (B) following a Key Man Event pursuant to Section 4.2(c) or
(C) if the Services Agreement is terminated, so long as the Company has not effected a Public Offering, Old Ironsides shall
have the right, at its express direction and in its sole discretion, to direct the Board to take such actions to effect a Liquidity
Event upon delivering a Liquidity Event Notice.

 

(b)       Upon
receipt of a Liquidity Event Notice, the Company shall use commercially reasonable efforts to consummate a Liquidity Event as soon
as practicable and shall diligently pursue the consummation of a Liquidity Event in good faith and the Board shall manage the business
and affairs of the Company primarily with a view toward the consummation of such Liquidity Event as soon as reasonably practicable
following the exercise of such right, and the approval of a Liquidity Event by an Old Ironsides Designee or a Yorktown Designee
shall be deemed approval of such Liquidity Event by the Board, subject to any approval required by Section 2.4(b)(v). Each
Member shall, and shall cause its Affiliates to, take all actions, including those set forth in Section 6.5(c), if applicable,
reasonably necessary or appropriate to (i) cooperate with the Company in working toward the consummation of a Liquidity Event
and (ii) cause its Board appointees to act in accordance with this Section 6.5 (including replacing its Board appointees,
if necessary).

 

    45

     

    

 

(c)       If
the Board approves (or is deemed to have approved) a Liquidity Event (an “Approved Exit”), each Member
shall raise no objections against such Approved Exit and, to the extent necessary to effect the consummation of such Approved Exit,
vote for and consent to such Approved Exit; provided, however, that any such vote, consent or approval by a Member shall
not constitute a waiver or otherwise affect any rights or obligations of any Member under this Section 6.5, or Section
6.6 of this Agreement with respect to such Approved Exit or any rights of a Member with respect to or arising as a result of
such Approved Exit under any agreement to which such Member is a party. If the Approved Exit is structured as a (i) merger, consolidation
or sale of assets, each Member shall waive any dissenters’ rights, appraisal rights or similar rights in connection with
such merger, consolidation or sale of assets or (ii) sale of Units, each Member shall agree to sell all of his, her or its Units
or rights to acquire Units on the terms and conditions approved by the Board (subject to Section 6.11). Each Member shall
take all necessary or desirable actions in connection with the consummation of the Approved Exit as reasonably requested by the
Board.

 

(d)       In
any Approved Exit, the consideration received by the Company shall be allocated and distributed to each Member in accordance with
Section 5.4 after all the liabilities of the Company have been satisfied in full or provided for.

 

(e)       Members
shall bear their pro rata share (based upon the allocation set forth in Section 6.5(d)) of the costs of any sale of Interests
pursuant to an Approved Exit to the extent such costs are incurred for the benefit of all Members and are not otherwise paid by
the Company or the acquiring party. For purposes of this Section 6.5, costs incurred by Members in exercising reasonable
efforts to take all actions in connection with the consummation of an Approved Exit in accordance with this Section 6.5
shall be deemed to be for the benefit of all Members. Costs incurred by Members solely on their own behalf will not be considered
costs of the transaction hereunder.

 

(f)       If
the Board determines that the Liquidity Event shall be a Public Offering:

 

(i)       each
Member agrees that it will, and will cause its Affiliates and any Director appointed by such Member to, and the Company shall:

 

(A)       if
the underwriters in any Public Offering request that all Members hold their Interest (or any equity securities of any Entity effecting
such Public Offering) for a period of time following the Public Offering, do so and enter into a customary lock-up agreement;

 

(B)       complete
and execute all consents, questionnaires, powers of attorney, indemnities, underwriting agreements and other documents as may reasonably
be required or advisable in connection with a Public Offering; provided that no such Person shall be required to make any representations
or warranties in connection with a Public Offering other than representations and warranties regarding such Person and, if applicable,
such Person’s intended method of distribution;

 

    46

     

    

 

(C)       if
determined by the Board to be reasonably necessary or appropriate in connection with a Public Offering, do all things reasonably
necessary or advisable to effect any Internal Restructure in accordance with Section 6.9;

 

(D)       consent
to certain additional restrictions on the Transfer of Interests (or any equity securities of any Entity effecting such Public Offering)
which the Board determines may be required in order to permit compliance with the Securities Act or other applicable law;

 

(E)       use
commercially reasonable efforts to accommodate any such other reasonable actions required by the United States Securities and Exchange
Commission or similar governmental authority to effect the Public Offering; and

 

(F)       make
modifications to this Agreement (or any other agreement then governing the rights and obligations of the Members with respect to
the Company or any successor to the Company) as are customary and appropriate for companies that conduct a Public Offering, such
modifications to be in form and substance reasonably satisfactory to Carbon and Old Ironsides.

 

(ii)       The
Company shall be responsible for its own costs, fees and expenses in connection with a Public Offering and shall reimburse the
Members and their Affiliates for the reasonable out-of-pocket costs, fees and expenses (excluding underwriting discounts, selling
commissions and similar fees) incurred by them in connection with a Public Offering, including the reasonable costs, fees and expenses
of one outside counsel for each Member.

 

(iii)       Each
of the Members shall be granted customary demand and piggyback registration rights effective from and after the Public Offering,
as well as the right to include their Interests (or any securities for which such Interests are exchanged or into which such Interests
are converted) in the Public Offering on a pro rata basis (based on the relative percentages of securities of this type to be included
in the Public Offering held by the Members immediately prior to the Public Offering); provided that if the managing underwriter
or the placement agent advises the Company or the Board that the inclusion of securities of the Members in the Company or any Affiliate
of the Company requested to be included for sale in a secondary offering in connection with the Public Offering would materially
and adversely affect the price, distribution or timing of the offering, then the Company shall have the right to exclude all or
any portion of such securities of the Company or any Affiliate of the Company from sale in connection with the Public Offering,
with such exclusions applied to the Members’ pro rata share of such securities (based on the relative percentages of securities
to be included in the Public Offering held by the Members immediately prior to the Public Offering).

 

(g)       Notwithstanding
anything to the contrary contained herein, if a Liquidity Event is not consummated during the period beginning as of the date a
Liquidity Event Notice is delivered to the Board through the first anniversary of such date and a Member thereafter seeks to Transfer
of its Interests, Board approval for such Transfer shall not be required pursuant to Section 6.1.

 

    47

     

    

 

Section 6.6Buy/Sell
Rights.

 

(a)       If
a Liquidity Event is not consummated during the period beginning as of the date of Liquidity Event Notice is delivered to the Board
through the first anniversary of such date, either Yorktown or Old Ironsides (the “Initiating Member”)
may initiate the buy sell procedure set forth in this Section 6.6 by delivering to the other (the “Non-Initiating
Member”) written notice specifying such Member’s determination of the Company Sale Value and the amount that
would be distributable to each holder of Units by applying Section 5.4 based on an amount equal to the Company Sale Value
as determined by such Member (giving effect to all distributions actually made pursuant to this Agreement through the date of the
transaction for purposes of allocations under Section 5.4) (such aggregate amount as would be distributable to each Member,
the “Buy/Sell Unit Price”), and the other terms and conditions pursuant to which the Initiating Member
proposes to purchase all of the Units held by the Non-Initiating Member (the “Offer”). If either Yorktown
or Old Ironsides has transferred all or a portion of its Units then Yorktown or Old Ironsides, as the case may be, and such transferee
(whether or not the transferee has been admitted as a Member or is only an assignee) will collectively be considered as Yorktown
or Old Ironsides, respectively, for purposes of this Section 6.6 and all Units held by Yorktown or Old Ironsides (including
all such transferees), as the case may be, shall be subject to purchase by the Initiating Member under the provisions of this Section
6.6.

 

(b)       No
later than thirty (30) days following receipt of the Offer, the Non-Initiating Member must notify (a “Buy/Sell Election
Notice”) the Initiating Member of its election to either:

 

(i)       sell
all Units held by the Non-Initiating Member and its Affiliates to the Initiating Member for a price equal to the applicable Buy/Sell
Unit Price and on such other terms specified in the Offer; or

 

(ii)       purchase
all Units held by the Initiating Member and its Affiliates for a price equal to the applicable Buy/Sell Unit Price; provided that
if the Initiating Member has transferred all or a portion of its Units, then the Units held by the Initiating Member and such transferees
(whether or not the transferee has been admitted as a Member or is only an assignee) will collectively be considered as held by
the Initiating Member for purposes of this Section 6.6(b)(ii) and Section 6.6(c) and Section 6.6(d) and the
Units held by the Initiating Member (including all such transferees) shall be subject to purchase by the Non-Initiating Member
under this Section 6.6.

 

(c)       If
the Non-Initiating Member fails to deliver a Buy/Sell Election Notice to the Initiating Member within the thirty (30) day period
(or fails to close the purchase in accordance with Section 6.6(d) within the time period set forth therein), then the Non-Initiating
Member will conclusively be deemed for all purposes to have elected to sell all Units held by the Non-Initiating Member as set
forth in Section 6.6(b)(i), and this deemed election will be treated as having occurred on the last day of the thirty (30)
day period (or ninety (90) day period under Section 6.6(d), if applicable).

 

    48

     

    

 

(d)       If
the Non-Initiating Member elects to purchase all Units held by the Initiating Member pursuant to Section 6.6(b)(ii), then
the closing of any sale under Section 6.6(b)(ii) to the Non-Initiating Member will be held at the principal office of the
Company, unless otherwise mutually agreed, on a mutually acceptable date not more than ninety (90) days after receipt by the Initiating
Member of the Non-Initiating Member’s Buy/Sell Election Notice electing to purchase the Units held by the Initiating Member.

 

(e)       If
the Non-Initiating Member elects to sell all of the Units held by the Non-Initiating Member pursuant to Section 6.6(b)(i)
or is deemed to have so elected pursuant to Section 6.6(c), then the Initiating Member may elect:

 

(i)       to
purchase such Units for the applicable Buy/Sell Unit Price with the closing of any sale to be held at the principal office of the
Company unless otherwise mutually agreed, on a mutually acceptable date not more than ninety (90) days after receipt by the Initiating
Member of the Buy/Sell Election Notice; provided that the Initiating Member may elect to assign its rights to purchase such Units
to any one or more other Persons (which assignment shall not relieve the Initiating Member of its obligations under this Section
6.6); or

 

(ii)       The
Initiating Member may seek a third party purchaser for one hundred percent (100%) of the Units whether through an equity sale or
a sale in any other form or a sale of the assets of the Company and/or its Subsidiaries (“Third Party Sale”).

 

(f)       The
Initiating Member must notify the Non-Initiating Member of its election of Section 6.6(e)(i) or Section 6.6(e)(ii)
within thirty (30) days after the Initiating Member’s receipt of the Buy/Sell Election Notice. If the Initiating Member fails
to timely notify the Non-Initiating Member of its election, then the Initiating Member shall be deemed to have made an election
of Section 6.6(e)(i).

 

(g)       If
the Initiating Member pursues a Third Party Sale:

 

(i)       The
Non-Initiating Member and the Company shall cooperate in the Initiating Member’s Third Party Sale process in any manner reasonably
requested by the Initiating Member. The Initiating Member will bear all costs and fees incurred in connection with the Third Party
Sale (including without limitation all reasonable and necessary third party costs and fees, including attorneys’ fees, incurred
by the Non-Initiating Member in cooperating in such Third Party Sale process), except each Member will bear the costs and fees
of its own independent advisors.

 

(ii)       The
Initiating Member will have the requisite authority to negotiate and approve the Third Party Sale (which Third Party Sale will
be conditioned on the consummation of the purchase or redemption of the Units of the Non-Initiating Member at the applicable Buy/Sell
Unit Price); and to this end the Initiating Member will have exclusive authority during this period to approve such a sale and
any related agreements without the necessity of obtaining the consent or approval of the Board or the other Member; provided,
however, that any representations and warranties relating specifically to any Member shall only be made by that Member and
any indemnification provided by the Members shall be made on a several, not joint, basis; provided further, however, that the Non-Initiating
Member shall be required to make only the Required Representations. In no event shall (A) the consideration to be received by any
Transferring Person in connection with a Third Party Sale consist of any form of non-cash consideration other than freely tradable
publicly traded securities (subject to any customary lockup not to exceed 90 days) or (B) the amount of any indemnity obligation
of any Transferring Person exceed the amount of cash and the fair market value of any non-cash consideration received by such Transferring
Person in such Third Party Sale, except in the case of fraud by such Transferring Person. Any indemnification or other obligation
assumed or incurred in connection with a Transfer shall be allocated among the Transferring Persons in the same proportion as the
consideration received by the Transferring Persons, in each case other than with respect to the Required Representations.

 

    49

     

    

 

(iii)       If
the Initiating Member successfully negotiates a Third Party Sale (other than as a sale of assets), then prior to or upon consummation
of the Third Party Sale, the Initiating Member will purchase the Units held by the other Members at the applicable Buy/Sell Unit
Price, or cause the purchaser in such Third Party Sale to purchase such Units at the applicable Buy/Sell Unit Price. The purchase
of such Units will be held at such time and place as will be elected by the Initiating Member but in any event not more than one
hundred twenty (120) days after the Initiating Member’s receipt of the Buy/Sell Election Notice, subject to extension for
such period of time (not to exceed thirty (30) days) as necessary to permit the Initiating Member or the third party purchaser
to obtain any required governmental approvals but in any event will occur no later than upon the consummation of the Third Party
Sale.

 

(iv)       If
the Initiating Member is unsuccessful in completing a Third Party Sale or the redemption or purchase of the Units held by the other
Members is not consummated within the time period specified in Section 6.6(g)(iii), then Initiating Member will purchase
the Units held by the Non-Initiating Member pursuant to Section 6.6(e)(i) within thirty (30) days after the one hundred
twenty (120) day period set forth in Section 6.6(g)(iii).

 

(h)       It
is expressly agreed that the remedy at law for breach of any of the obligations set forth in this Section 6.6 is inadequate
in view of (i) the complexities and uncertainties in measuring the actual damages that would be sustained by reason of the failure
of a Member to comply with each of said obligations, and (ii) the uniqueness of the Company’s business and the Company’s
relationship with the Members. Accordingly, each of the aforesaid obligations will be, and are hereby expressly made, enforceable
by specific performance.

 

(i)       Notwithstanding
anything contained in this Section 6.6, each transferee of a Member’s Units or any interest therein shall be subject
to the terms of this Section 6.6 (whether or not such transferee has been admitted as a Member) but a Member who has transferred
its Units or any interest therein to any Person shall not be liable or responsible for any noncompliance or compliance, respectively,
with this Section 6.6, by any such transferee of such Member who is not an Affiliate of such Member.

 

    50

     

    

 

Section 6.7Assumption
of Assignee. Any Transfer of an Interest in the Company permitted under this Article VI must be in writing, and
the assignee must expressly, in a written joinder executed by the assignee, (a) agree to be bound by the terms of this Agreement,
(b) assume and agree to perform all of the Transferring Member’s agreements and obligations existing or arising with
respect to the assigned Interest after the Transfer and (c) make the representations and warranties set forth in Section 3.8
to the Company and to the other Members effective as of the date of Transfer. Upon such Transfer and joinder, (i) the Transferring
Member will be relieved of its agreements and obligations arising under this Agreement after the date of the Transfer (but not
before) to the extent of the Interest assigned, and if one hundred percent (100%) of that Member’s Interest is Transferred,
such Member will be deemed to have withdrawn from the Company and (ii) the assignee shall be admitted as a Member with respect
to the Interests acquired upon consummation of such Transfer and compliance with this Section 6.7. An executed copy
of each assignment of an Interest in the Company and the assignee’s joinder must be delivered to each Member and to the Company.
Except as otherwise expressly provided herein, no permitted Transfer of any Interests will cause a termination or winding-up of
the Company.

 

Section 6.8Allocations
to Member’s Transferee. Upon the Transfer of all or any part of the Interest of a Member, the profits, distributions,
net losses, net gains and credits attributable to the Interest Transferred will be allocated, at the sole cost and expense of the
transferee and/or transferor, between the transferee and transferor as of the date set forth in the instrument of transfer, based
upon a manner that complies with Section 706 of the Code and the Treasury Regulations thereunder, as determined by the Board of
Directors.

 

Section 6.9Internal
Restructure.

 

(a)       Subject
to the consent of the Board of Directors in accordance with Article II, the Company may effect an Internal Restructure
on such terms as the Board of Directors in the exercise of its reasonable discretion deems advisable. Each Member agrees that it
will consent to and raise no objections to an Internal Restructure; provided that (i) the Internal Restructure is undertaken in
a manner that results in the Members continuing to have substantially the same direct or indirect ownership of the Company’s
assets in place prior to the Internal Restructure, (ii) the Internal Restructure preserves the relative economic interests, preferences,
priorities and designations of the Members in the Company or any entity that succeeds to the Company in such Internal Restructure
transaction, and (iii) such Member does not determine, based on written advice of counsel, that the Internal Restructure has a
reasonable risk of having an adverse legal, regulatory, tax or accounting effect on such Member. Each Member hereby agrees that
it will execute and deliver all agreements, instruments and documents as are required, in the reasonable judgment of the Board
of Directors to be executed by such Member in order to consummate the Internal Restructure while continuing in effect, to the extent
consistent with such Internal Restructure, the terms and provisions of this Agreement, including those provisions granting the
Board authority to manage the affairs of the Company, granting certain persons the right to nominate and cause the election of
Directors, governing Transfers of Interests in the Company or other equity securities and indemnification.

 

    51

     

    

 

(b)       The
Members acknowledge that an Internal Restructure may be undertaken in connection with other events, such as a public offering of
the Company or an acquisition of another business or entity and, if so determined by the Board of Directors, such Internal Restructure
shall be deemed completed immediately before any such event.

 

(c)       The
Members acknowledge that, to engage in an initial public offering, it may be necessary or advisable for the Company to merge or
convert into a Delaware corporation (a “Conversion”). Accordingly, if the Board of Directors determines
it to be in the best interests of the Company to engage in an initial public offering and to effect a Conversion, the Members agree
that the Company’s capital structure shall be restructured in the manner described in this Section 6.9 and the Members
shall vote and take all other action necessary in order to effect such Conversion. In connection with a Conversion, all Interests
in the Company (the “Old Interests”) will be exchanged for common stock of the surviving corporation
(the “Conversion Consideration”). In determining the portion of the Conversion Consideration to be exchanged
for the Old Interests, the Company shall determine what portion of the Conversion Consideration would have been distributed among
all of the holders of the Old Interests if the Company’s sole asset consisted of the Conversion Consideration and the Company
distributed the Conversion Consideration in the same manner distributions would have been made in a complete liquidation of the
Company taking into account the various rights, preferences and designations governing the Old Interests (which rights, preferences
and designations are set forth in this Agreement, each as they may exist before the Conversion). Once the Company determines the
portion of the Conversion Consideration that would have been distributed to each class or series of Old Interests if the Company
had been liquidated immediately before the Conversion, the Board of Directors will then determine the exchange ratio of the Old
Interest into common shares of the surviving corporation.

 

(d)       Upon
the consummation of an Internal Restructure, the surviving entity or entities shall assume or succeed to all of the outstanding
debt and other liabilities and obligations of the Company. To the extent practicable, the governing instruments of the surviving
entity shall incorporate the governance provisions of this Agreement. All Members shall take such actions as may be reasonably
required and otherwise cooperate in good faith with the Company in connection with consummating an Internal Restructure including
a Conversion including voting for or consenting thereto.

 

Section 6.10Other
Assignment Void. Any purported Transfer of an Interest in the Company not permitted by this Article VI is null
and void ab initio and of no effect whatsoever.

 

Section 6.11Allocation
and Distribution of Consideration. Upon any Transfer of Units in which two or more holders of Units Transfer Units pursuant
to a Liquidity Event, Internal Restructure or pursuant to Section 6.2 or Section 6.3:

 

(a)       The
Fair Market Value of any non-cash property included in the consideration for such Transfer shall be added to the aggregate cash
proceeds included in the consideration for such Transfer to determine the aggregate proceeds of such Transfer (the “Disposition
Proceeds”). Each holder of Units included in such Transfer shall receive such holder’s (i) proportionate share
of the aggregate non-cash consideration comprising the Disposition Proceeds and (ii) proportionate share of the aggregate cash
consideration comprising the Disposition Proceeds, in each case determined in accordance with Section 6.11(b) below.

 

    52

     

    

 

(b)       For
purposes of determining the proportionate share of the Disposition Proceeds to be delivered to each holder whose Units are included
in such Transfer, the following provisions shall apply:

 

(i)       with
respect to a Transfer in which all outstanding Units are Transferred (A) the Company shall be deemed to have distributed pursuant
to Section 5.4 an amount equal to the Disposition Proceeds (giving effect to all prior distributions under Section 5.4
and Section 5.5) and (B) the amount that would be distributable to each holder of Units pursuant to the hypothetical distribution
in accordance with Section 6.11(b)(i)(A) on account of such holder’s Units shall be the amount of such Disposition
Proceeds to be paid to such holder;

 

(ii)       with
respect to any Drag-Along Sale or Tag-Along Sale that includes less than all outstanding Class A Units and in which Class B Units
are included pursuant to Section 6.2(h) or Section 6.3(e), (A) the Board shall determine a Company Sale Value
based on the purchase price offered for the Class A Units as set forth in the Tag-Along Notice, (B) the Board shall assume that
an amount of cash equal to such Company Sale Value was distributed pursuant to Section 5.4 (giving effect to all prior distributions
under Section 5.4 and Section 5.5 through the date of the Tag-Along Sale for purposes of determining the appropriate
distributions under Section 5.4), (C) each holder of Class B Units whose Class B Units are included in such Tag-Along Sale
shall be allocated a portion of the Disposition Proceeds with respect to such holder’s Class B Units equal to the amount
that would be distributable on account of such holders’ Class B Units by applying Section 5.4 to a distribution amount
equal to such Company Sale Value in accordance with Section 6.11(b)(ii)(B), and (D) each holder of Class A Units and each
holder of Class C Units participating in such Tag-Along Sale shall be allocated, with respect to such holder’s Class A Units
and Class C Units included in such Tag-Along Sale, a portion of the balance of the Disposition Proceeds remaining after giving
effect to clause (C) above (the “Remaining Tag Balance”), equal to the Remaining Tag Balance multiplied
by a fraction, (x) the numerator of which is the amount that would be distributable to such holder in the hypothetical distribution
in accordance with Section 6.11(b)(ii)(B) on account of such holder’s Class A Units and/or Class C Units being
included in such Tag-Along Sale and (y) the denominator of which is the amount that would be distributable to all holders of Class
A Units and Class C Units participating in such Tag-Along Sale on account of such holders’ Class A Units and Class C Units
being included in such Tag-Along Sale by applying Section 5.4 to a distribution amount equal to such Company Sale Value
in accordance with Section 6.11(b)(ii)(B) (subject to any adjustment as necessary to give effect to any different economic
attributes of the Class A Units being Transferred if such Class A Units being Transferred by a holder of Class A Units have different
economic attributes relative to Class A Units being Transferred by other holders of Class A Units).

 

(iii)       with
respect to any Drag-Along Sale or Tag-Along Sale that includes less than all outstanding Class A Units and in which Class B Units
are not included pursuant to Section 6.2(h) or Section 6.3(e), (A) the Company shall be deemed to have distributed
pursuant to Section 5.4 an amount equal to the Disposition Proceeds on account of the Class A Units and Class C Units
being Transferred in such Tag-Along Sale (giving effect to all prior distributions under Section 5.4 and Section 5.5
but assuming that no proceeds are distributable on account of the Class B Units) and (B) the amount that would be distributable
to each holder pursuant to the hypothetical distribution in accordance with Section 6.11(b)(iii)(A) on account of such holder’s
Class A Units and Class C Units being Transferred in such Tag-Along Sale shall be the amount of such Disposition Proceeds to be
paid to such holder (subject to any adjustment as necessary to give effect to any different economic attributes of the Class A
Units being Transferred if such Class A Units being Transferred by a holder of Class A Units have different economic attributes
relative to Class A Units being Transferred by other holders of Class A Units); and

 

    53

     

    

 

(iv)       for
purposes of determining the amount of the Disposition Proceeds to be allocated among and/or delivered for the Class A Units, Class
B Units and Class C Units pursuant to an Internal Restructure or Transferred in a Liquidity Event, other than as described in Section
6.11(b)(i), the methodology set forth in Section 6.11(b)(ii) and Section 6.11(b)(iii) shall apply, mutatis
mutandis.

 

Section 6.12Yorktown-Carbon
Assignment.

 

(a)       Yorktown
may assign all or any portion of its Interests to Carbon in exchange for shares of common stock of Carbon, subject to Section
6.1(b) and Section 6.7 (such assignment, the “Yorktown-Carbon Assignment“). Effective
upon any Yorktown-Carbon Transfer, Carbon shall succeed to the rights of Yorktown with respect to the Interests assigned by Yorktown
to Carbon. In the event that Yorktown assigns all of its Interests to Carbon pursuant to a Yorktown-Carbon Transfer, Yorktown shall
be deemed withdrawn as a Member of the Company and Carbon shall succeed to the rights and obligations of Yorktown under this Agreement
with respect to the Interests assigned by Yorktown to Carbon (including the right to appoint Board designees and the obligation
to make Capital Contributions under Article IV).

 

(b)       If
the Yorktown-Carbon Assignment occurs, the terms agreed to by Yorktown and Carbon with respect to the Yorktown-Carbon Assignment
shall not be taken into account for purposes of Company Sale Value or otherwise with respect to the value of the Company or its
assets.

 

(c)       If
the Yorktown-Carbon Assignment occurs, the Members will act in good faith to amend and restate the Agreement to give effect to
the Yorktown-Carbon Assignment and the purpose and intent of this Section 6.12.

LIABILITY AND INDEMNIFICATION

 

Section 8.1No
Liability for Company Debts. The debts, obligations and liabilities of the Company, whether arising in contract, tort or otherwise,
shall be solely the debts, obligations and liabilities of the Company, and no Covered Person shall be liable for any such debts,
obligations or liabilities. Additionally, except as otherwise expressly required by Law, no Member, in its capacity as a Member,
shall have any liability in excess of (a) the amount of its Capital Contributions, (b) its share of any assets and undistributed
profits of the Company, (c) its obligation to make other payments expressly provided for in this Agreement and (d) the amount of
any Distributions wrongfully distributed to it.

 

Section 8.2Indemnification.
To the fullest extent permitted by Law, the Company shall indemnify each Covered Person from and against any and all Covered Losses
arising from any and all claims, demands, causes of action, actions, suits or proceedings, whether civil, criminal, administrative
or investigative, in which such Covered Person may be involved, or is threatened to be involved, as a party or otherwise, by reason
of its status as such, regardless of whether any of the foregoing arise from the sole, partial or concurrent negligence of such
Covered Person; provided, however, that the Company shall not indemnify a Covered Person for Covered Losses arising directly
from fraud, intentional or willful misconduct, gross negligence or a knowing violation of the Law or a breach of the terms of any
Transaction Agreement that is materially related to the claim giving rise to the Covered Losses, for which the Covered Person is
seeking indemnification. The termination of any action, suit or proceeding by judgment, order, settlement or upon a plea of nolo
contendere, or its equivalent shall not, of itself, create a presumption that the Covered Person failed to meet the standards for
indemnification set forth in the immediately preceding sentence. Any indemnification hereunder shall be satisfied solely out of
the assets of the Company (subject to Section 5.6(b)). In no event may a Covered Person subject the Members to personal
liability by reason of these indemnification provisions. The indemnification provided by this Section 8.2 shall be
in addition to, but not duplicative of, any other rights to which a Covered Person or any other Person may be entitled under any
agreement to which the Company is a party, pursuant to any vote of the Members, as a matter of Law or otherwise, and shall continue
as to a Covered Person who has ceased to serve in such capacity and shall inure to the benefit of the heirs, successors, assigns
and administrators of the Covered Person.

 

Section 8.3Advance
Payment and Appearance as a Witness. To the fullest extent permitted by applicable Law, expenses (including legal fees) incurred
by a Covered Person in defending any claim, demand, cause of action, action, suit or proceeding shall, from time to time, be advanced
by the Company prior to the final disposition of such claim, demand, cause of action, action, suit or proceeding upon receipt by
the Company of an undertaking by or on behalf of the Covered Person to repay such amount if it shall be determined that the Covered
Person is not entitled to be indemnified as authorized in Section 8.2. The Company shall pay or reimburse expenses
incurred by a Person who is or was a Member, Manager, officer or employee of the Company in connection with their appearance as
a witness or other participant in a proceeding at a time when they are not a named defendant or respondent in the proceeding.

 

    56

     

    

 

Section 8.4Insurance.
The Company shall procure and maintain insurance, to the extent and in such amounts as approved by the Board of Directors, in its
sole discretion, on behalf of Covered Persons and such other Persons as the Board of Directors shall determine, against any liability
that may be asserted against or expenses that may be incurred by any such Person in connection with the activities of the Company
or such indemnities, regardless of whether the Company would have the power to indemnify such Person against such liability under
the provisions of this Agreement. The Company may enter into indemnity contracts with Covered Persons and adopt written procedures
pursuant to which arrangements are made for the advancement of expenses and the funding of obligations under Section 8.3
and containing such other procedures regarding indemnification as are appropriate. The insurance as in effect for the Company as
of the Effective Date is set forth on Exhibit F, and any reduction in the amount of insurance coverage from as set forth
on Exhibit F shall require approval of a Supermajority of the Voting Power.

 

Section 8.5Non-exclusivity
of Rights; Company as Indemnitor of First Resort. The indemnification and advancement of expenses provided by, or granted pursuant
to, this Article VIII shall not be deemed exclusive of, and shall not limit, any other rights or remedies to which
any Covered Person may be entitled or which may otherwise be available to any Covered Person at Law or in equity. The Company hereby
acknowledges that the Covered Persons may have certain rights to indemnification, advancement of expenses and/or insurance provided
by the Members and certain of their Affiliates (collectively, the “Member Indemnitors”). The Company
hereby agrees that (a) the Company is the indemnitor of first resort for matters covered by this Article VIII (i.e., its
obligations to the Covered Persons under Article VIII are primary and any obligation of the Member Indemnitors to advance
expenses or to provide indemnification for the same expenses or liabilities incurred by the Covered Persons are secondary), (b)
the Company shall be required to advance the full amount of expenses incurred by the Covered Persons and shall be liable for all
expenses, liabilities, judgments, penalties, fines and amounts paid in settlement to the extent legally permitted and as required
by the terms of Article VIII (or any other agreement between the Company and the Covered Persons), without regard to any
rights the Covered Persons may have against the Member Indemnitors, and (c) the Company irrevocably waives, relinquishes and releases
the Member Indemnitors from any and all claims against the Member Indemnitors for contribution, subrogation or any other recovery
of any kind in respect thereof. The Company further agrees that no advancement or payment by the Member Indemnitors on behalf of
a Covered Person with respect to any claim for which the Covered Person has sought indemnification from the Company pursuant to
Article VIII shall affect the foregoing and the Member Indemnitors shall have a right of contribution and/or be subrogated
to the extent of such advancement or payment to all of the rights of recovery of the Covered Persons against the Company. The Company
agrees that the Member Indemnitors who are not Members are express third party beneficiaries of the terms of this Section 8.5.

 

    57

     

    

 

Section 8.6Savings
Clause. If all or any part of this Article VIII shall be invalidated for any reason by any court of competent jurisdiction,
the Company shall nevertheless indemnify and hold harmless each Covered Person, and may indemnify and hold harmless any other Person,
for costs, charges, expenses (including attorneys’ fees), judgments, fines and amounts paid in settlement, in connection
with any claim, to the fullest extent permitted by any portion of this Article VIII not invalidated and to the fullest
extent otherwise permitted by applicable Law.

under applicable Law, such Member agrees that, prior to disclosing any Confidential Information, it shall (i) immediately notify
the Board of Directors of the existence and terms of, and the circumstances attendant to, such request or advice, (ii) consult

Information as is required to be disclosed.

 

(b)       Notwithstanding
the above, a Member or a member of the Board of Directors may disclose Confidential Information (i) to the extent the disclosure

of this Agreement.

 

Section 12.5Waiver
or Consent. A waiver or consent, express or implied, to or of any breach or default by any Person in the performance of its
obligations with respect to the Company is not a consent or waiver to or of any other breach or default in the performance by that
Person of the same or any other obligations of that Person with respect to the Company. Failure on the part of a Person to complain
of any act or omission of any Person or to declare any Person in breach or default with respect to an obligation, irrespective
of how long that failure continues, shall not be construed as a waiver of the breach or default until the applicable statute of
limitations has run. No waiver of any obligation under this Agreement or the Act shall be effective unless in writing signed by
or on behalf of the Person or Persons to whom the obligation is owed.

 

Section 12.6Amendment.
No amendment of this Agreement shall be effective (by merger, consolidation or otherwise) unless such amendment is executed by
all of the Class A Members; provided, however, that no Member approval shall be required for any amendment made (x) to Exhibit A
in accordance with the last sentence of this Section 12.6, (y) to reflect admission of a new Member approved pursuant to
Section 2.4(a)(xii) or effected pursuant to Section 6.7 or (z) in connection with the creation and issuance
of additional or different classes or series of Units approved pursuant to Section 2.4(a)(xi); and, provided, further,
that (i) the approval of the holder of the Class B Units shall be required for any amendment that adversely affects the right of
the Class B Units under Article V of this Agreement relative to the rights of the Class A Units and Class C Units under
this Agreement in any material respect, (ii) the approval of the holder of the Class C Units shall be required for any amendment
that adversely affects the right of the Class C Units under Article V of this Agreement relative to the rights of the Class
A Units and Class B Units under this Agreement in any material respect and (iii) at any time there is a Defaulting Member, the
approval of the Defaulting Member (in its capacity as a Class A Member) shall not be required for any amendment of this Agreement
provided that such amendment does not materially and adversely affect the rights of the Defaulting Member in its capacity as a
holder of Class A Units in a manner that is disproportionate to the other holders of Class A Units. Neither the waiver by the Company
or a Member of a breach of or a default under any of the provisions of this Agreement, nor the failure of the Company or a Member,
on one or more occasions, to enforce any of the provisions of this Agreement or to exercise any right, remedy or privilege hereunder,
shall thereafter be construed as a waiver of any subsequent breach or default of a similar nature, or as a waiver of any such provisions,
rights, remedies or privileges hereunder. Exhibit A shall be amended from time to time to reflect any changes to the
information contained therein without the necessity of any Board or Member approval.

 

Section 12.7Choice
of Law. This Agreement shall be constructed, interpreted and enforced in accordance with, and the respective rights and obligations

or filing with respect to the Company or its affairs or the transactions provided for herein without the prior written consent
of the other Member(s), which shall not be withheld unreasonably, except as may be required by law.

 

Section 12.9Availability
of Equitable Relief. Each of the parties hereto recognizes that irreparable injury may result from a breach of any provision
of this Agreement and that money damages may be inadequate to fully remedy the injury. In order to prevent such irreparable injury,
a party hereto may seek temporary injunctive relief from any court of competent jurisdiction.

 

Section 12.10Binding
Agreement. This Agreement shall be binding upon and inure to the benefit of the parties hereto and their respective successors
and assigns (it being understood and agreed that, except as expressly provided herein and the rights of Covered Persons and Member
Indemnitors under Article VIII, nothing contained in this Agreement is intended to confer any rights, benefits or remedies
of any kind or character on any other Person under or by reason of this Agreement). It is expressly understood and agreed that
any attempted or purported Transfer by any party of this Agreement in violation of the provisions of this Section 12.10
shall be null and void.

 

Section 12.11Benefit
of Agreement. Nothing in this Agreement expressed or implied, shall be construed to give to any creditor of the Company or
of any Member any legal or equitable right, remedy or claim under or in respect of this Agreement.

any additional documents and instruments and to perform any additional acts necessary or appropriate to effectuate the provisions

Drilling
Commitment; Subsequent Activities

 

2.1Carry
Wells.

 

(a)       Carbon
TN Mining Co hereby commits to participate in the drilling, completing and equipping of up to twenty (20) Carry Wells, subject
to the terms hereof, which will be operated by Operator on the lands in the Tennessee Mining Tract.

 

(b)       The
Parties shall bear the costs and expenses associated with the Carry Wells in accordance with Section 3.1(a).

 

2.2Carry
Wells – Process.

 

(a)       Not
less than thirty (30) days prior to the anticipated spud date of each Well proposed by Operator to be drilled in the Tennessee
Mining Tract, in each case prior to Operator making a proposal for such Well under the terms of the Operating Agreement, Operator
shall deliver to Carbon TN Mining Co written notice of Operator’s intent to spud such Well, which shall include a description
of the location of such Well, the proposed depth and target formation of such Well, and an AFE, setting forth drilling, completion
and surface equipment costs for such Well (each a “Well Notice and AFE”). It is understood and agreed
that the AFE applicable to a proposed Well represents an estimate of the costs of drilling and completing the applicable Well,
but final billing will be based on actual costs incurred. In connection with any Well Notice and AFE, Operator agrees promptly
to provide any additional information regarding the Well which is reasonably requested by Carbon TN Mining Co.

 

(b)       Following
delivery to Carbon TN Mining Co of a Well Notice and AFE (excluding Approved Set Well Notices relating to Approved Set
Wells), Carbon TN Mining Co will have fifteen (15) days after its receipt of such Well Notice and AFE to elect, in writing,
to either participate or not participate in the drilling and completion of such proposed Well (and, for the avoidance of
doubt, a decision not to participate in such proposed Well will not be subject to Section 2.4). Carbon TN Mining
Co’s failure to deliver to Operator written notice of its election within such period shall be deemed an election by
Carbon TN Mining Co to not participate in the drilling or completion of such Well. Any Well that Carbon TN Mining Co elects
to participate in pursuant to this Section 2.2(b) will be deemed an “Initial Carry Well”.

2.4 Reassignment. If
during the Term of this Agreement:

 

(a)       Carbon
TN Mining Co fails to pay the Drilling and Completion Costs of the first Initial Carry Well or one or more Approved First Set
Wells as contemplated by Section 3.1(a) and such well is drilled and completed by Operator, then Carbon TN Mining Co shall,
pursuant to recordable assignment in substantially the form attached hereto as Exhibit D (a “Partial Reassignment”),
promptly reassign to Nytis, without consideration, an undivided twenty five percent (25%) of the Carbon TN Mining Co Working Interest
assigned to Carbon TN Mining Co by Nytis pursuant to the Assignment;

 

(b)       Carbon
TN Mining Co fails to pay the Drilling and Completion Costs of the second Initial Carry Well or one or more Approved Second Set
Wells as contemplated by Section 3.1(a) and such well is drilled and completed by Operator, then Carbon TN Mining Co shall,
pursuant to a Partial Reassignment, promptly reassign to Nytis, without consideration, an undivided twenty five percent (25%)
of the Carbon TN Mining Co Working Interest assigned to Carbon TN Mining Co by Nytis pursuant to the Assignment;

 

(c)       Carbon
TN Mining Co fails to pay the Drilling and Completion Costs of the third Initial Carry Well or one or more Approved Third Set

of the Carbon TN Mining Co Working Interest assigned to Carbon TN Mining Co by Nytis pursuant to the Assignment;

 

    C-7

     

    

 

notwithstanding
anything in this Section 2.4 to the contrary, (i) if any reassignment by Carbon TN Mining Co pursuant to Sections
2.4(a) through (d) is required, such assignment will exclude all of Carbon TN Mining Co’s rights
and interest in any Approved Spacing Unit surrounding each Carry Well in which Carbon TN Mining Co has previously
participated in accordance with terms and conditions of this Agreement and (ii) under no circumstances shall Carbon TN Mining
Co be required to make more than a single reassignment pursuant to each of Sections 2.4(a) through (d) (for
example, if Carbon TN Mining Co fails to pay the Drilling and Completion Costs of two Approved First Set Wells and both such
Wells are drilled and completed by Operator, Carbon TN Mining Co would be required to make a single reassignment upon the
completion of the first such Approved First Set Well pursuant to Section 2.4(a), but would not be required to make a
second reassignment upon the completion of the second such Approved First Set Well). Reassignment pursuant to this Section
2.4 shall be the sole remedy of Nytis (including in its capacity as Operator) for any failure of Carbon TN Mining Co to
comply with its obligations pursuant to Section 3.1(a)(i).

 

Notwithstanding
anything herein to the contrary, Carbon TN Mining Co shall not be required to make any reassignment pursuant to this Section
2.4 from and after such time as Carbon TN Mining Co has paid an aggregate amount of Carry Costs equal to or greater than the
Aggregate Carry Cap or has paid the Shortfall Carry Payment Amount.

 

2.5 Subsequent
Activities. Following the expiration of the Term, the Parties may proceed to drill additional Wells on
the Tennessee Mining Tract in accordance with the terms of the Operating Agreement with all Drilling and Completion
Costs associated with such additional Wells borne in accordance with the terms of the Operating Agreement on a heads up
basis (i.e., borne as provided in the Operating Agreement, without application of Section 3.1(a)(i)).

Payment
of Carry Costs; Assignment

 

3.1 Purchase
of Working Interest. In accordance with the payment terms of the applicable Operating Agreement, unless
otherwise set forth herein:

 

(a)       (i)
Carbon TN Mining Co agrees to be responsible for and pay Drilling and Completion Costs as follows: with respect to the
Carry Wells, subject to Section 3.1(b), Carbon TN Mining Co shall bear (A) the Carry Costs for the benefit of Nytis,
plus (B) the Drilling and Completion Costs for such Wells that are allocated to be borne by Carbon TN Mining Co pursuant to
the terms of the Operating Agreement (being, as of immediately following the Closing, seventy-five percent (75%) of the
Drilling and Completion Costs, Proportionally Reduced) for the benefit of Carbon TN Mining Co.

 

(ii)       Nytis
agrees to be responsible for and pay Drilling and Completion Costs as follows: with respect to the Carry Wells, the Direct Nytis
Costs, if any, for the benefit of Nytis.

 

(iii)       For
(A) any Excess Costs and (B) any Wells drilled subsequent to the expiration of the Term, the Parties shall bear the Drilling
and Completion Costs for such Wells in accordance with the terms of the Operating Agreement on a heads up basis (i.e.,
borne as provided in the Operating Agreement, without application of Section 3.1(a)(i)).

 

For
the avoidance of doubt, Schedule F reflects the allocation of Drilling and Completion Costs with respect to Carry Wells
as provided in Section 3.1(a)(i) and (ii); provided that the allocations set forth on Schedule F are subject
to Section 3.1(a)(iii) and Section 3.1(b).

 

(b)       Notwithstanding
anything to the contrary in Section 3.1(a)(i), the maximum amount of Carry Costs to be borne by Carbon TN Mining Co will
be (i) for each Carry Well, 110% of the aggregate estimate of the costs of drilling and completing such Carry Well as set forth
in the applicable AFE and (ii) for all Carry Wells in the aggregate, the Aggregate Carry Cap. To the extent that the Carry Costs
with respect to any Carry Well would otherwise exceed the thresholds set forth in the preceding sentence (any such excess, “Excess
Costs”), such Excess Costs will be borne as provided in Section 3.1(a)(iii) and not Section 3.1(a)(i).
The maximum number of Carry Wells to be drilled and completed pursuant to this Agreement is twenty (20).

 

(c)       Carbon
TN Mining Co Disposals. If Carbon TN Mining Co disposes of all or substantially all of the Carbon TN Mining Co Working Interest
in an arms-length transaction for fair market value paid in cash prior to the expiration of the Term (the aggregate amount by
which the Carry Costs previously paid by Carbon TN Mining Co is less than the Aggregate Carry Cap as of such time, a “Carry
Shortfall”), then Carbon TN Mining Co shall pay to Nytis, concurrently with the closing of such disposition of the
Carbon TN Mining Co Working Interest, an amount, in cash in immediately available funds, equal to the lesser of (i) the Carry
Shortfall and (ii) the proceeds actually received by Carbon TN Mining Co in connection with such disposition, net of any taxes
and expenses payable by Carbon TN Mining Co or its direct or indirect owners as a result of or in connection with such disposition.
The amount of any Carry Shortfall paid to Nytis pursuant to this Section 3.1(c) (the “Carry Shortfall Payment
Amount”) will be deemed to be a payment of Carry Costs by Carbon TN Mining Co for purposes of Section 3.1(b),
and following the payment of the Carry Shortfall Payment Amount, Carbon TN Mining Co will have no further obligation or liability
pursuant to Section 3.1(a)(i).

 

3.2Assignment. Simultaneously
with the Closing hereof, Nytis shall deliver to Carbon TN Mining Co a recordable assignment, in substantially the form
attached hereto as Exhibit E (the “Assignment”), assigning to Carbon TN Mining Co
seventy-five percent (75%) of all of Nytis’ undivided right, title and interest in and to the Leases. The Assignment
shall be made with a warranty of title, by, through and under Nytis, but not otherwise, and such assignment(s) shall be
subject to the terms contained in this Agreement and the applicable operating agreements and/or pooling orders, if any.

5.2       Nytis
Representations and Warranties. Nytis hereby represents and warrants to Carbon TN Mining Co as follows:

 

(a)       There
are no bankruptcy, reorganization or rearrangement proceedings pending, being contemplated by or to its knowledge threatened against
it.

 

(b)       None
of the lands underlying the Leases which will be assigned to Carbon TN Mining Co will be subject to liens burdening Carbon TN
Mining Co’s interest therein, including but not limited to any liens in favor of LegacyTexas Bank (“LegacyTexas”),

Leases are in full force and effect and are legal, valid and binding obligations of the parties thereto, their respective successors
and assigns. Operations with respect to the Wells are in material compliance with applicable rules, regulations, statutes, and
laws of any applicable governmental authority. To the best of Nytis’ knowledge and belief, after appropriate inquiry, Nytis
is not in breach or default under the terms of any of the Leases which may result in material impairment or loss of title to any
material part of the Leases taken as a whole or the value thereof taken as a whole or which might materially hinder or impede

(d)       Nytis
has delivered to Carbon TN Mining Co all Phase I or Phase II environmental site assessment reports in Nytis’
possession or control on the Leases or the lands covered thereby. To the best of Nytis’ knowledge and belief, after
appropriate inquiry, Nytis has complied in all material respects with all environmental laws with respect to the Leases. To
the best of Nytis’ knowledge and belief, after appropriate inquiry, Nytis possesses all environmental permits
that are required for the operation of the Leases (except for such permits as are expected to be obtained in the ordinary
course of business), and is in compliance with the provisions of all such environmental permits. Nytis has not received any
written notice, report or other information regarding any liabilities relating to its business or any of the Leases arising
under environmental laws, including any written notice of violation from any governmental authority. To the best of
Nytis’ knowledge and belief, after appropriate inquiry, Nytis has not treated, stored, disposed of, arranged for or
permitted the disposal of, transported, handled, or released any substance, including any hazardous materials, or owned or
operated any facility or property, so as to give rise to liabilities for response costs, natural resource damages or
attorneys fees pursuant to federal or state environmental laws. Without limiting the foregoing, no facts, events or
conditions relating to the past or present facilities, properties or operations of Nytis with respect to the Leases will
prevent, hinder or limit continued compliance with environmental laws, give rise to any investigatory, remedial or corrective
obligations on the part of Carbon TN Mining Co pursuant to environmental laws, or give rise to any other liabilities on the
part of Carbon TN Mining Co (whether accrued, absolute, contingent, unliquidated or otherwise, whether due or to become due,
and regardless of whether asserted) pursuant to environmental laws, including any relating to onsite or offsite releases or
threatened releases of hazardous materials, substances or wastes, personal injury, property damage or natural resource
damage.

 

(e)       The
information set forth on Schedule 5.2(e) with respect to the working interest and net revenue interest of Nytis in the
Leases is true and correct.

 

(f)       Schedule
5.2(f) sets forth a list of all policies of insurance owned or held by or maintained by Nytis with respect to the Leases.
Such policies are in full force and effect and, coupled with the insurance to be obtained under any applicable Operating Agreement,
will satisfy in all material respects all requirements of applicable, laws and any agreements to which Nytis is a party.

 

(g)       Prior
to the execution of this Agreement, Nytis will have obtained, or cause to be obtained, any consents, approvals, certificates,
licenses, permits, and other authorizations of the necessary governmental authorities, which to (i) the best of Nytis’ knowledge
and belief, after appropriate inquiry, are required for Nytis to own, develop, operate, and maintain the Tennessee Mining Tract
and (ii) are required for Nytis to effect the transfer of the Carbon TN Mining Co Working Interest pursuant to the Assignment.

 

(h)       Nytis
has paid its pro-rata share of all ad valorem, property, production, severance, excise, and similar taxes and assessments with
respect to the Leases that have become due and payable, and all tax returns required to be filed by Nytis with respect to the
same have been timely filed. To the best of Nytis’ knowledge and belief, after appropriate inquiry, with respect to the
Leases there are no tax deficiencies assessed against or audits in progress by any governmental authority. There are no tax liens
on or with respect to the Leases.

 

(i)       All
rentals, royalties, shut-in royalties, overriding royalties and other payments due pursuant to or with respect to the Leases have
been properly paid.

 

    C-11

     

    

 

(j)       To
the best of Nytis’ knowledge and belief, after appropriate inquiry, there are no wells located on the Leases that (a) Nytis
is obligated by law or contract to plug and abandon; (b) Nytis would be obligated by law or contract to plug and abandon with
the lapse of time or notice or both because the well is not capable of producing oil, gas or other hydrocarbons in commercial
quantities or otherwise being used in normal operations; (c) are subject to exceptions to a requirement to plug and abandon issued
by a regulatory authority having jurisdiction over the Leases; or (d) have been plugged and abandoned but have not been plugged
in accordance, in all material respects, with all applicable requirements of each regulatory authority having jurisdiction over
the Leases.

Leases are not subject to any preferential purchase rights applicable to the transactions contemplated hereby.

 

(l)       There
are no outstanding AFEs with respect to wells located on the lands subject to the Leases or other capital commitments which are
binding on the Leases.

 

5.3Carbon
TN Mining Co Representations and Warranties. Carbon TN Mining Co hereby represents and warrants to Nytis as
follows:

 

(a)       There
is no bankruptcy, reorganization or arrangement proceedings pending, being contemplated by or to its knowledge threatened against

working interests being acquired by Carbon TN Mining Co are being acquired for investment purposes only, for Carbon TN Mining
Co’s own account, and not with a current view to, for offer for sale or for sale in connection with, the distribution or
transfer thereof. The working interests being acquired by Carbon TN Mining Co are not being purchased for subdivision or fractionalization
thereof; and Carbon TN Mining Co has no contract, agreement or arrangement with any person or entity to sell or otherwise transfer
(with or without consideration) to any such person or entity any of the working interests being acquired by Carbon TN Mining Co,

Each indemnified party hereunder agrees that promptly upon its discovery of facts giving rise to a claim for indemnity
under the provisions of this Agreement, including receipt by it of notice of any demand, assertion, claim, action or proceeding,
judicial or otherwise, by any third party (such third party actions being collectively referred to herein as the “Indemnity
Claim”), with respect to any matter as to which it claims to be entitled to indemnity under the provisions of this
Agreement, it will give prompt notice thereof in writing to the indemnifying party or parties, together with a statement of such
information respecting any of the foregoing as it shall have. Such notice shall include a formal demand for indemnification under
this Agreement. The indemnifying party or parties shall not be obligated to indemnify the indemnified party with respect to any
Indemnity Claim if the indemnified party knowingly failed to notify the indemnifying party or parties thereof in accordance with
the provisions of this Agreement in sufficient time to permit the indemnifying party or parties or its/their counsel to defend
against such matter and to make a timely response thereto including, without limitation, any responsive motion or answer to a
complaint, petition, notice or other legal, equitable or administrative process relating to the Indemnity Claim, only insofar
as such knowing failure to notify the indemnifying party has actually resulted in prejudice or damage to the indemnifying party
or parties.

 

9.5Reimbursement.
The indemnifying party or parties shall pay to the indemnified party in immediately available funds any amounts to
which the indemnified party may become entitled by reason of the provisions of this Agreement, such payment to be made within
five (5) days after any such amounts are finally determined either by mutual agreement of the parties hereto or pursuant to the
final unappealable judgment of a court of competent jurisdiction. In calculating any amount to be paid by an indemnifying party
or parties by reason of the provisions of this Agreement, the amount shall be reduced by all tax benefits and other reimbursements
credited to or received by the other party related to the damages.

 

    C-14

     

    

 

9.6Survival.
The representations and warranties of the parties set forth in Section 5.1 shall survive the execution of this
Agreement indefinitely. All other representations and warranties of Nytis and Carbon TN Mining Co made on the date of execution
of this Agreement shall survive the execution of this Agreement for a period of two (2) years. All other covenants and agreements
contained in this Agreement shall survive the execution of this Agreement until this Agreement is terminated in accordance with
Section 6.2; provided, however, that the indemnification provisions of this ARTICLE 9 shall survive
the execution of this Agreement indefinitely.

 

9.7Exclusive
Remedy. The terms and provisions of this ARTICLE 9 shall be the sole and exclusive remedy of each of the parties
indemnified hereunder with respect to the representations, warranties, covenants and agreements of the parties set forth in this
Agreement and the other documents executed and delivered hereunder, except with respect to any breach of the special warranty
of title contained in the Assignment,.

 

9.8Assumption
of Liability. Each party that is required to assume any obligation or liability of the other party pursuant to this
Agreement or that is required to defend, indemnify or hold the other party harmless hereunder shall, notwithstanding any other
provision hereof to the contrary, be entitled to the use and benefit of all defenses (legal and equitable) and counterclaims of
such other party in defense of third party claims arising out of any such assumption or indemnification.

 

ARTICLE

Relationship
of Parties

 

It
is not the purpose or intention hereof to create any mining partnership, joint venture, general partnership or other partnership
relation and none shall be inferred. The parties understand and agree that their relationship hereunder is not one of partnership,
association, trust, joint venture, mining partnership or entity of any kind. The parties intend, however, that pursuant to the
provisions of Subchapter K of Chapter 1 of Subtitle A of the Internal Revenue Code, the arrangement created under this Agreement
is to be treated as a partnership for U.S. federal and state income tax purposes, and each party agrees not to elect to be excluded
from the applicable provisions of said Subchapter K. Therefore, the parties agree to be governed by the Tax Partnership Agreement
attached as Exhibit G to the Operating Agreement. In the event of a conflict between the terms of the Operating Agreement or this
Agreement and the terms and provisions of the Tax Partnership Agreement, the Tax Partnership Agreement shall prevail over the
terms of both this Agreement and the Operating Agreement. For U.S. federal and state income tax purposes (a) the tax partnership
will be treated as (i) holding Nytis’ and CAC’s interests in the Tennessee Mining Tract and the Leases and (ii) engaging
in all activities of the parties with respect to such interests in the Tennessee Mining Tract and the Leases; (b) Nytis will be
treated as contributing its existing interests in the Tennessee Mining Tract and the Leases to the tax partnership in exchange
for an interest in the tax partnership; (c) CAC will be treated as contributing its interests in the Tennessee Mining Tract and
the Leases received pursuant to this Agreement to the tax partnership in exchange for an interest in the tax partnership, (d)
CAC and Nytis will be treated as making capital contributions to the tax partnership in amounts equal to their shares of the costs
incurred pursuant to this Agreement or the Operating AGreement, as they make payments attributable to such costs, and (e) from
and after its commencement, the tax partnership will be treated as realizing all items of income or gain and incurring all items
of cost or expense attributable to the ownership, operation or disposition of such interests in the Tennessee Mining Tract and
the Leases notwithstanding that such items are realized, paid or incurred by parties individually.

Force Majeure

 

If
any party is rendered unable, wholly or in part, by force majeure to carry out its obligations under this Agreement, other than
an obligation to make payments of money, such party shall give to the other party prompt written notice of the force majeure with
reasonably full particulars concerning it; thereupon, the obligations of the party giving the notice, so far as they are affected
by the force majeure, shall be suspended during, but no longer than, the continuance of the force majeure. The affected party
shall use all reasonable diligence to remove the force majeure situation as quickly as practicable. The requirement that any force
majeure shall be remedied with all reasonable dispatch shall not require the settlement of strikes, lockouts or other labor difficulties
by the party involved, contrary to its wishes; how any such difficulties shall be handled shall be entirely within the discretion
of the party concerned. The term “force majeure”, as here employed, shall mean an act of God, strike, lockout or other
industrial disturbance, act of the public enemy, war, blockade, public riot, lightning, fire, storm, flood, explosion, governmental
action, governmental delay, restraint or inaction, and any other cause, whether of the kind specifically enumerated above or otherwise,
which is not reasonably within the control of the party claiming suspension.

Marketing

 

Operator
shall cause production of oil and gas for Carbon TN Mining Co from the Wells and any other wells drilled and completed by the
parties on the Tennessee Mining Tract to be gathered, processed, treated, transported and marketed by Operator or third parties,
after reasonable consultation with Carbon TN Mining Co, with no “mark-up” costs and/or internal fees from Operator
or its affiliates to Carbon TN Mining Co; provided, however, that Operator may charge Carbon TN Mining Co the typical
overhead fees relating to such activities included within the standard COPAS Accounting Procedure annexed to the Operating Agreement.
Any marketing agreement(s) entered into with third parties with respect to production of oil and gas for Carbon TN Mining Co from
the Wells and any other wells drilled and completed by the parties on the Tennessee Mining Tract will be (i) for term(s) of no
longer than twelve (12) months and (ii) otherwise on current market terms on the same basis that production of oil and gas for
Nytis from the Wells and any other wells drilled and completed by the parties on the Tennessee Mining Tract is marketed.
