 “If this Agreement is terminated
pursuant to the terms and conditions of this Agreement on or after December 31, 2032, then Shipper shall have the option (to be exercised by providing written notice to Gatherer prior to the termination of the Agreement) to continue to receive
the Services or a portion of the Services, under a new agreement, for all or any portion of its volumes of Crude Oil on a year-to-year basis on the same terms and
conditions as the most favorable terms and conditions under a then-effective agreement with any third party pursuant to which Gatherer provides a basket of services for an initial term (excluding any renewals or extensions of any kind) of at least
[***] for volumes of Crude Oil utilizing any System Segment located within the “Most Favored Nations Dedication Area” as identified on Exhibit K attached hereto (other than any pipeline facilities physically connected or independent
of a System Segment after the Effective Date, in each case, in connection with an acquisition, joint venture, or partnership by and between Gatherer and a third party), that are the same or substantially similar in nature to the basket of Services
during the term hereunder, unless and until such third party agreement is terminated. For avoidance of doubt, the Services Gatherer is to offer Producer in accordance with the proceeding sentence shall only apply to Services on the Gathering System.

December 31, 2042. Gatherer shall provide copies to Shipper of any such third party agreements applicable to volumes of Crude Oil accessing the Gathering System upon any notice of termination of this Agreement (whether such notice is delivered
by Gatherer, Producer or Shipper); provided, however, that to the extent Gatherer is prohibited by an obligation of confidentiality from disclosing any such third party agreement to Shipper, then (a) Gatherer shall not be
obligated to disclose such agreement to Shipper until Gatherer has obtained the right to disclose such agreement and (b) Gatherer shall exercise reasonable efforts to obtain the right to disclose such agreement to Shipper.”

Oil at each such CDP. If a generator is necessary for electrical power to be used by Producer and Gatherer, then Producer shall procure, install, operate, and maintain such generator to fulfill the power requirements of the Parties and Gatherer
shall pay its prorated portion of the reasonable capital costs (including reasonable rental and installation costs) therefor; provided, however, that Producer will continue to use all reasonable efforts to obtain access to electrical
power at such CDP, thereby minimizing the time such generator is needed (rather than a local electric utility) to provide electrical power at such CDP.” 

(iv)    Effective as of the Effective Date, the following sentence is hereby added as Section 9.2(e) of the Crude Oil
Agreement—Wild Basin:

Section 8.2(c), Producer shall be solely liable for any claims or losses arising out of or related to such Saltwater that meets the Saltwater Quality Specifications, and (ii) at Producer’s sole cost and expense,
(X) Producer shall be responsible for the construction, ownership, operation, and maintenance of any facilities utilized or needed to transport such Saltwater from the applicable delivery point or other CDP at which such Saltwater is

redelivered Barrel of Saltwater, but no Disposal Fee shall be owed therefor; and 
 (k) upon request of Producer, allow
Producer to remove Barrels of Dedicated Saltwater upstream of the Receipt Points for Producer to utilize for purposes of operating Producer’s Wells in an Agreed Formation located on a Dedicated Property, including for frac recycling, treatment,

the Gathering Fee for each such removed Barrel of Saltwater, but no Disposal Fee shall be owed therefor.” 

(ii)    Effective as of the Effective Date, Section 4.2 of the Produced Water Agreement—Beartooth Area is hereby
deleted in its entirety and replaced with the following: 
 “If this Agreement is terminated pursuant to the terms and conditions of
this Agreement on or after December 31, 2032, then Producer shall have the option (to be exercised by providing written notice to Gatherer prior to the termination of the Agreement) to continue to receive the Services or a portion of the
Services, under a new agreement, for all or any portion of its volumes of Saltwater on a year-to-year basis on the same terms and conditions as the most favorable terms
and conditions under a then-effective agreement with any third party pursuant to which Gatherer provides a basket of services for an initial term (excluding any renewals or extensions of any kind) of at least [***] for volumes of Saltwater utilizing
any System Segment located within the Dedicated Acreage (other than any pipeline facilities physically connected with or independent of a System Segment after the Effective Date, in each case, in connection with an acquisition, joint venture, or
partnership by and between Gatherer and a third party), that are the same or substantially similar in nature to the basket of Services during the term hereunder, unless and until such third party agreement is terminated. For avoidance of doubt, the
Services Gatherer is to offer Producer in accordance with the proceeding sentence shall only apply to Services on the Gathering System. 

  
 12 

 If the option to extend the term of this Agreement on a year-to-year basis pursuant to this Section 4.2 is exercised, any obligation of Gatherer to continue to provide the Services pursuant to such option shall not extend beyond
December 31, 2042. Gatherer shall provide copies to Producer of any such third party agreements applicable to volumes of Saltwater accessing the Disposal System upon any notice of termination of this Agreement (whether such notice is delivered
by Gatherer or Producer); provided, however, that to the extent Gatherer is prohibited by an obligation of confidentiality from disclosing any such third party agreement to Producer, then (a) Gatherer shall not be obligated to
disclose such agreement to Producer until Gatherer has obtained the right to disclose such agreement and (b) Gatherer shall exercise reasonable efforts to obtain the right to disclose such agreement to Producer.” 

(iii)    Effective as of the Effective Date, Section 7.3 of the Produced Water Agreement—Beartooth Area is
hereby deleted in its entirety and replaced with the following: 
 “Subject to the rest of the provisions of this
Section 7.3, Producer will (i) use reasonable efforts to obtain access to electrical power at each CDP and (ii) provide electrical power to Gatherer at each CDP at Producer’s sole cost and expense. In
designing and constructing its electrical facilities at each CDP, Producer will cooperate with Gatherer and take into account the amount of electrical power that is reasonably necessary for Gatherer’s facilities to receive Producer’s
Saltwater at each such CDP. If a generator is necessary for electrical power to be used by Producer and Gatherer, then Producer shall procure, install, operate, and maintain such generator to fulfill the power requirements of the Parties and
Gatherer shall pay its prorated portion of the reasonable capital costs (including reasonable rental and installation costs) therefor; provided, however, that Producer will continue to use all reasonable efforts to obtain access to
electrical power at such CDP, thereby minimizing the time such generator is needed (rather than a local electric utility) to provide electrical power at such CDP.” 

(iv)    Effective as of the Effective Date, the following is hereby added to Section 14.3 of the Produced Water
Agreement—Beartooth Area after the period at the end of the first sentence: 
 “If and to the extent Gatherer redelivers Saltwater
to Producer in accordance with Section 3.1(j), then title to and risk of loss attributable to such redelivered Saltwater, including all constituents, contaminants and skim oil thereof, shall transfer from Gatherer to
Producer at each applicable delivery point or other CDP.” 
 (v)    Effective as of the Effective Date,
Section 16.4(b)(iii) of the Produced Water Agreement—Beartooth Area is hereby deleted in its entirety and replaced with the following: 

“Producer shall have the right to assign its rights under this Agreement, in whole or in part, as applicable, without the consent of
Gatherer, to any Person with a credit rating equal to or better than Producer’s credit rating as of the Effective Date and to whom Producer sells, assigns or otherwise Transfers all or any portion of the Dedicated Properties and who assumes in
writing all of Producer’s obligations hereunder (if applicable, to the extent of the Dedicated Properties being Transferred to such Person) and, upon such assignment, Producer shall be released from its obligations under this Agreement to the
extent of such assignment. If the Person to whom Producer intends to sell, assign or otherwise Transfer all or any portion of the Dedicated Properties has a credit rating worse than Producer’s credit rating as of the Effective Date, then,
Producer shall have the right to assign its rights under this Agreement, in whole or in part, as applicable, without the consent of Gatherer, to such Person if, as a condition precedent to such assignment, at Producer’s option, either:
(A) Producer and the assignee execute an amendment to this Agreement with Gatherer that sets forth creditworthiness requirements to which Gatherer agrees such assignee will be subject under this Agreement for the remainder of the term, or
(B) Producer remains liable for its obligations under this Agreement to the extent of such assignment, or (C) the assignee agrees to provide a letter of credit from a major U.S. commercial bank for the benefit of Gatherer in an amount
equal to 60 days of the aggregated Fees under this Agreement that are reasonably estimated to become due and payable by assignee upon the assignment; provided that, upon such assignment, in each case of (A) and (C), Producer shall be released
from its obligations under this Agreement to the extent of such assignment.”

Gatherer and take into account the amount of electrical power that is reasonably necessary for Gatherer’s facilities to receive Producer’s Crude Oil at each such CDP. If a generator is necessary for electrical power to be used by Producer
and Gatherer, then Producer shall procure, install, operate, and maintain such generator to fulfill the power requirements of the Parties and Gatherer shall pay its prorated portion of the reasonable capital costs (including reasonable rental and

Summary of Rights of Shareholders (as of December 2021)
We are a British Virgin Islands company and our affairs are governed by our memorandum and articles of association and the Companies Law of the British Virgin Islands, which we refer to as the “Companies Law” below, and the common law of the British Virgin Islands.
The following are summaries of material provisions of our memorandum and articles of association and the Companies Law as they relate to the material terms of our ordinary shares.
Registered Office and Objects
Our registered office in the British Virgin Islands is at the offices of Maples Finance BVI Limited, Kingston chambers, Road Town, Tortola, British Virgin Islands.
We are established for unrestricted purposes, and we have full power and authority to carry out any object not prohibited by the Companies Law or any other law of the British Virgin Islands.
Board of Directors
The business and affairs of the Company shall be managed by the directors who may exercise all such powers of the Company as are not by the Company Act or by the Memorandum or the Articles required to be exercised by the members of the Company, subject to any delegation of such powers as may be authorized by the Articles and to such requirements as may be prescribed by a resolution of members; but no requirement made by a resolution of members shall prevail if it be inconsistent with the Articles not shall such requirement invalidate any prior act of the directors which would have been valid if such requirement had not been made.
The minimum number of directors shall be five and there shall be no maximum number. The directors may by a resolution of directors change the number of directors. For as long as the Company’s shares are listed on Nasdaq, the Directors shall include such number of independent directors as applicable law, regulations or the Nasdaq regulations required for a foreign private issuer as long as the Company is a foreign private issuer. The continuing directors may act, notwithstanding any casual vacancy in their body, so long as there remain in office not less than the prescribed minimum number of directors duly qualified to act, but if the number falls below the prescribed minimum, the remaining directors shall not act except for the purpose of filling such vacancy. Any vacancy on the Board of Directors resulting from death, resignation, removal or other cause and any newly created directorship resulting from any increase in the authorized number of directors between meetings of members may be filled either by the affirmative vote of a majority of all the directors then in office (even if less than a quorum) or by a resolution of members.
Directors are not required to own any ordinary shares to act as a director. Directors must be an individual person.
The directors shall receive such remuneration as the Board may from time to time determine.
Director Nominations by Shareholders
Shareholders nominations, other than those made by or at the direction of the directors, shall be made pursuant to timely notice in writing to the secretary of the company. To be timely, a members’ notice shall be delivered to or mailed and received at the principal executive offices of the Company not less than 60 days nor more than 90 days prior to the anniversary date of the prior year’s annual meeting; provided, however, that in the event that the date of the annual meeting changed by more than 30 days from such anniversary date, notice by the member to be timely must be so received not later than the close of business on the tenth day following the day on which public disclosure is first made of the date of the annual meeting. Any adjournment or postponement of the original meeting whereby the meeting will reconvene within 30 days from the original date shall be deemed for the purposes of this notice to be a continuation of the original meeting and no nominations by a member of persons to be elected directors of the Company may be made at any such reconvened meeting unless pursuant to a notice which was timely for the meeting on the date originally scheduled. Each such notice shall set out:
		(i)	the name and address of the member who intends to make the nomination and of the persons to be nominated;

		(ii)	a representation that the member is a holder of record of shares in the Company entitled to vote at such meeting and that he intends to appear in person or by a proxy at the meeting to nominate the persons specified in the notice;

​

		(iii)	a description of all arrangements at understandings between the member and each nominee and any other person (naming such person) pursuant to which the nominations are to be made by the member;

		(iv)	such other information regarding each nominee proposed by such member as would have been required to be included in a proxy statement filed pursuant to the proxy rules of the United States Securities and Exchange Commission, had each nominee been nominated, or intended to be nominated, by the directors;

		(v)	the consent of each nominee to serve as a director of the Company if so elected; and

		(vi)	if the member intends to solicit proxies in support of such member’s nominees, a representation to that effect.

The chairman of the meeting may refuse to acknowledge the nomination of any person not made in compliance with the aforegoing procedure. Only such persons as are nominated in accordance with the procedures shall be eligible to serve as directors of the Company. If at any meeting of members at which an election of directors ought to take place, the place of any retiring director is not filled, he shall, if willing, continue in office until the dissolution of the annual meeting of members in the next year, and so on from year to year until his place is filled, unless it shall be determined at such meeting not to fill such vacancy.
A director shall cease to hold office as such only: (a) if he becomes of unsound mind; (b) if (unless he is not required to hold a share qualification) he has not duly qualified himself within two months of his appointment or if he ceases to hold the required number of shares to qualify him for office; (c) if he is absent from meetings of the directors for six consecutive months without leave of the board of directors, provided that the directors shall have power to grant any director leave of absence for any or an indefinite period; (d) if he dies; (e) one month or, with the permission of the directors earlier, after he has given notice in writing of his intention to resign; (f) if he shall, pursuant to the provisions of the Act, be disqualified or cease to hold office or be prohibited from acting as director; (g) if he is removed from office by a resolution signed by a majority of the directors; or (h) if he is removed from office for cause by a resolution of members. For the purposes hereof, cause means the willful and continuous failure by a director to substantially perform his duties to the Company (other than any such failure resulting from incapacity due to physical or mental illness) or the willful engaging by the director in gross misconduct materially and demonstrably injurious to the Company; or (i) if he is removed from office without cause by a resolution of the majority of the members of the Company, being an affirmative vote of the holders of 66 2/3 percent or more of the outstanding votes of the shares entitled to vote thereon.
Ordinary and Preferred Shares
The Company is authorized to issue two classes of shares as follows: (a) 60,000,000 shares in one series of no par value ("Ordinary Shares"); and (b)1,000,000 preference shares in one series of no par value ("Preferred Stock"). The Company may issue fractional Shares and a fractional Share shall have the corresponding fractional rights, obligations and liabilities of a whole Share of the same class or series of shares. All of our issued and outstanding ordinary shares are fully paid and non-assessable. Our ordinary shares are issued in registered form and are issued when registered in our register of members. We may not issue share to bearer. Our shareholders who are non-residents of the British Virgin Islands may freely hold and transfer their ordinary shares.
The Board of Directors of the Company is authorized to amend the Company’s memorandum and articles of association to provide for the creation from time to time of one or more classes of shares of preferred stock, and pursuant to such amendment, to establish the number of shares and series to be included in each such class, and to fix the designation, relative rights, preferences, qualifications and limitations of the shares of each such class.
