Section 3.6 of the Shareholders Agreement shall be deleted in its entirety and replaced with the following: 

Section 3.6 CERTAIN AGREEMENTS. 
 (a) Upon the reasonable request of the Investor Shareholders holding Voting Securities representing a majority of the Total Voting Power of all Voting Securities then held by the Investor Shareholders
(with respect to which the Company shall not unreasonably object), the Company shall, with regard to any Subsidiaries of the Company, cause the directors nominated to the Board by the Investor Shareholders pursuant to Article III (considered
as a group) to be appointed or elected to the boards or governing bodies of such Subsidiaries of the Company (other than KMGP, KMP, KMR, EPGP, EPB or any of their Subsidiaries) so that the Investor Shareholders (as a group) have, as closely as is
practicable, the same proportionate representation on such boards or governing bodies (or, with respect to Subsidiaries of the Company that become publicly traded after the date hereof (other than any Subsidiaries of KMR, KMP or EPB) on the seats of
such boards or governing bodies for which the Company has the right to designate directors; provided, that the Investor Shareholders shall have agreed to the limitation on the ability of the Company to designate directors of such
Subsidiaries) as they do on the Board. 
 (b) The Company shall (i) permit the Board nominees chosen by the Investor
Shareholders and each Observer of the Investor Shareholders permitted to attend meetings of the Board pursuant to Section 3.2 (together, the “Partnership Observers”) to attend each meeting of the KMGP board, the EPGP
board and the KMR board and any committees thereof, (ii) send to each Partnership Observer notice of the time and place of such meeting, (iii) provide to each Partnership Observer copies of all notices, reports, minutes and consents at the
time and in the manner as they are provided to the members of the KMGP, EPGP and KMR boards and the relevant committees thereof; provided, however, that the KMGP, EPGP and KMR boards, and committees thereof, shall have the right to
exclude the Partnership Observers from access to any board or committee meeting (or portion thereof) or any materials distributed to any board or committee members in the sole discretion of a majority of the members of such board or committee in
attendance at such board or committee meeting (or, with respect to materials to be provided in advance of any meeting, a majority of the members of such board or committee, as applicable). A Partnership Observer shall recuse himself or herself from
any portion of any board or committee meeting if (i) such Partnership Observer has actual 

  
 3 








 
knowledge that the Investor Shareholder that selected such Partnership Observer, or one of its controlled Affiliates, is engaged in, pursuing or evaluating any business opportunity that such
Partnership Observer has actual knowledge that the Company or any of its Subsidiaries is either currently engaged in, pursuing or evaluating and the participation of such Partnership Observer would create a conflict of interest and (ii) such
business opportunity is being discussed during such portion of such meeting (provided, that for the avoidance of doubt, no Partnership Observer shall be deemed to be in breach of his or her obligations pursuant to this sentence so long as such
Partnership Observer recuses himself or herself from such portion of such meeting as promptly as practicable following the time in which it becomes reasonably apparent that such business opportunity is being discussed). All Partnership Observers, in
connection with exercising their rights under this Section 3.6(b), shall be required (i) to execute and deliver to KMGP, EPGP or KMR, as applicable, a customary (for observers of public corporations) confidentiality agreement that
is reasonably acceptable to such Partnership Observer and to KMGP, EPGP or KMR, as applicable, (ii) to undergo any training required by KMP’s, KMGP’s, KMR’s, EPB’s or EPGP’s policies regarding FERC standards of conduct
that are applicable to KMGP , EPGP or KMR directors, as applicable, and (iii) to comply with any other regulatory requirements to the extent applicable to such Partnership Observer in his or her capacity as a Partnership Observer. 

(c) So long as an Investor Shareholder constitutes an Eligible Investor Shareholder, the Company shall inform such Eligible Investor
Shareholder promptly of any action or proposed action by the Company or any of its Affiliates (including KMP, EPB and KMR) that the Chief Executive Officer reasonably believes could impose any filing obligation, restriction or other regulatory
burden (e.g., bank holding company registration, or public utility holding company registration) on such Eligible Investor Shareholder or its Affiliates. In addition, neither the Company nor any of its Subsidiaries or Affiliates (other than
KMP, KMP’s operating partnerships, KMR, EPB or any of their respective Subsidiaries or controlled Affiliates, or KMGP (solely to the extent that KMGP (i) is acting in its capacity as a holder of shares of KMR or in its capacity as General
Partner pursuant to Section 1.4 of the Delegation of Control Agreement to approve any action taken by KMR, or (ii) is acting in its capacity as the general partner of KMP or any of its operating partnerships to approve any matter on
behalf of KMP or any of its operating partnerships (and not to the extent acting in another capacity, such as acting to amend or waive a right or obligation of KMGP (or of its direct or indirect parent entities) under any organizational document of
KMP or its operating partnerships)) or EPGP (solely to the extent that EPGP is acting in its capacity as the general partner of EPB with respect to the business and affairs of EPB or to approve any matter on behalf of EPB (and not to the extent
acting in another capacity, such as acting to amend or waive a right or obligation of EPGP (or of its direct or indirect parent entities) under any organizational document of EPB)) or KMGP Services Company, Inc. to the extent it is taking action
related to carrying out the terms of the Employee Services Agreement dated as of January 1, 2001 (not including amendments or waivers), among KMGP Services Company, Inc., KMGP and KMP) will take any action (or authorize any of, commit, agree or
propose to take any of, consent to or vote in favor of any action) that would 

  
 4 








 
impose any filing obligation, restriction or other regulatory burden (e.g., bank holding company registration, or public utility holding company registration) on any Eligible Investor
Shareholder or its Affiliates that such Eligible Investor Shareholder reasonably determines could have a significant impact on the interests of such Eligible Investor Shareholder or its Affiliates (other than its interests as a Shareholder), without
approval by such Eligible Investor Shareholder (it being understood that such limitation shall not be read to prohibit acquisitions that may prohibit future acquisitions by such Investor Shareholder or its Affiliates due to antitrust overlaps).

 (d) So long as an Investor Shareholder constitutes an Eligible Investor Shareholder, the Company shall keep such Eligible
Investor Shareholder informed, on a current basis, of any events or changes with respect to any criminal or regulatory investigation or action involving the Company or any of its Affiliates, so that such Eligible Investor Shareholder and its
Affiliates will have the opportunity to take appropriate steps to avoid or mitigate any regulatory consequences to them that might arise from such investigation or action. 
 (e) So long as an Investor Shareholder constitutes an Eligible Investor Shareholder, the Company shall reasonably cooperate with such Eligible Investor Shareholder and its Affiliates in efforts to
mitigate consequences of circumstances described in clause (c) or (d) (i.e., coordinating and assistance in meeting with regulators). Each Investor Shareholder who receives any non-public information pursuant to clause (c) or
(d) agrees (i) to use it only in connection with purposes related to the subject matter of clauses (c), (d) or (e), as applicable, and (ii) to maintain the disclosed information in confidence, except as required by applicable law
or applicable national securities exchange rule or to the extent that such information (A) enters the public domain through no fault of such Investor Shareholder or (B) is later lawfully acquired by such Investor Shareholder on a
non-confidential basis from sources other than the Company and its Subsidiaries. 
 (f) Each Executive Management Shareholder
agrees that he or she shall not, during the Non-Compete Period, directly or indirectly (other than on behalf of or at the request of the Company or its Subsidiaries): 

(i) engage in, have an interest in, or otherwise be employed by (whether as an owner, operator, partner, member, manager,
employee, officer, director, consultant, advisor, or representative), provide consulting or management services to, or permit his or her name to be used in connection with the activities of, any business or organization, engaged in a business that
is competitive with a business in which the Company or any of its Subsidiaries engages (a “Competitive Business”); provided, that ownership of less than one percent (1%) of the outstanding stock of any publicly traded
corporation shall not be deemed to be a violation of this Section 3.6(f) solely by reason thereof; provided, further, that, providing investment banking or legal services to a Competitive Business as an independent
consultant, independent advisor or independent representative shall not be deemed to be a violation of this Section  

  
 5 








 
3.6(f) solely by reason thereof so long as providing such services is not the primary duties or business activities of such individual; provided, further, that, if the Board
determines that the provisions of this Section 3.6(f)(i) should not apply to an Executive Management Shareholder (other than Kinder or Shaper) following the termination of such Executive Management Shareholder’s employment by the
Company, the provisions of this Section 3.6(f)(i) shall be deemed waived with respect to such Executive Management Shareholder; 
 (ii) solicit any Person who is or, within the prior twelve (12) months, was, or whose Affiliate is or, within the prior twelve (12) months, was a customer of the Company or any of its
Subsidiaries or persuade or attempt to persuade any such Person not to be a customer of the Company or any of its Subsidiaries or to reduce the amount of business that such customer does with the Company or any of its Subsidiaries, or enter into or
seek to enter into any agreement (to the extent such agreement is of a nature that is related to the business in which the Company or any of its Subsidiaries engage) with, to the Executive Management Shareholder’s knowledge, any such Person; or

 (iii) contact, approach or solicit for the purpose of offering employment to or hiring or retaining, or
actually hire or retain any Person who is or was employed or retained by the Company or its Affiliates as an employee during the immediately preceding twelve (12) months or attempt to persuade any Person not to continue to be employed or
retained by the Company or its Affiliates or to terminate his or her employment or services with the Company or its Affiliates; provided, that notwithstanding the foregoing, general solicitations of employment published in a journal,
newspaper or other publication of general circulation and not specifically directed towards such employees, consultants or independent contractors shall not be deemed to constitute solicitation for purposes of this Section 3.6(f)(iii).

 (iv) Notwithstanding anything to the contrary in this Section 3.6(f), with respect to the country
of Mexico, this Section 3.6(f) will only apply (and therefore will be limited) to activities that are competitive with the businesses in which any of the Mexican Subsidiaries of the Company engages. 

Each Executive Management Shareholder acknowledges and agrees that: (A) the time and geographical scope of the restrictions of this
Section 3.6(f) are reasonable; (B) the burden on the Executive Management Shareholder of complying with the restrictions of this Section 3.6(f) is not unreasonable; (C) the general public policy is not harmed by the
restrictions of this Section 3.6(f); and (D) the restrictions of this Section 3.6(f) are necessary for the protection of the Company and its Subsidiaries. Each Executive Management Shareholder further acknowledges and
agrees (x) the Executive Management Shareholder’s breach of the provisions of this Section 3.6(f) will cause the Company irreparable harm, which cannot be adequately compensated by money damages, (y) if the Executive
Management Shareholder breaches or threatens to breach the provisions of this Section 3.6(f) and the Company (by vote of a majority of the 

  
 6 








 
members of the Board) seeks an injunction against the Executive Management Shareholder, there is a reasonable probability of the Company’s eventual success on the merits and (z) if the
Executive Management Shareholder breaches or threatens to breach the provisions of this Section 3.6(f) and the Company (by vote of a majority of the members of the Board) seeks an injunction against the Executive Management Shareholder,
a balancing of equities will be in favor of the Company. Each Executive Management Shareholder consents and agrees that if the Executive Management Shareholder commits any such breach or threatens to commit any breach, the Company (by vote of a
majority of the members of the Board) shall be entitled to temporary and permanent injunctive relief from a court of competent jurisdiction, without posting any bond or other security and without the necessity of proof of actual damage, in addition
to, and not in lieu of, such other remedies as may be available to the Company for such breach, including the recovery of money damages. If any of the provisions of this Section 3.6(f) are determined to be wholly or partially
unenforceable, each Executive Management Shareholder hereby agrees that this Agreement or any provision hereof may be reformed so that it is enforceable to the maximum extent permitted by law. If any of the provisions of this
Section 3.6(f) are determined to be wholly or partially unenforceable in any jurisdiction, such determination shall not be a bar to or in any way diminish the Company’s right to enforce any such covenant in any other jurisdiction.

 (g) So long as an Investor Shareholder constitutes an Eligible Investor Shareholder, the Company shall not, and shall not
cause any of its Subsidiaries to, take any action, and shall take all actions as a shareholder within its power to prevent its Subsidiaries from taking any action to cause the board of KMGP to consist of less than a majority of individuals who
qualify as independent directors under the Exchange Act and the standards established by each national securities exchange upon which securities of KMP are listed for trading. 
 (h) Except as otherwise provided in this Section 3.6(h), the Company shall not, directly or indirectly, engage in any Charter Change of Control that does not constitute a Cash Change of
Control (a “Non-Cash Change of Control”) without the unanimous affirmative vote of all holders of Shares unless the organizational documents and capital structure of the acquiring, surviving or resulting Person in the Non-Cash
Change of Control preserve in all material respects the economic and other rights (including conversion, Transfer, distribution and governance rights as set forth in the Charter, the Bylaws and this Agreement) and characteristics and tax treatment,
including on a relative basis, of the Investor Shareholders, the Class A Shares, the Class B Shares, the Class C Shares and the Class P Shares as they exist immediately prior to such Non-Cash Change of Control (a “Replicated Change of
Control”) (and if such rights are so preserved, then the unanimity requirement stated above shall not apply and in lieu thereof, the regular approval requirements that would otherwise be applicable shall apply instead). 

  
 7 








 (i) A determination that such Non-Cash Change of Control satisfies the
requirements, set forth in paragraph (h) above, to be a Replicated Change of Control shall require approval by the following: (A) the Investor Shareholders holding Voting Securities representing a majority of the Total Voting Power then
held by the Investor Shareholders that continue to hold Class A Shares, (B) Kinder (so long as Kinder (together with his Permitted Transferees) continues to hold Class A Shares), (C) the holders of Class B Shares representing a
majority of the issued and outstanding Class B Shares (not to be unreasonably withheld or delayed) and (D) the holders of Class C Shares representing a majority of the issued and outstanding Class C Shares (not to be unreasonably withheld or
delayed). If the requisite Shareholders approve a Non-Cash Change of Control as a Replicated Change of Control pursuant to this Section 3.6(h)(i), then the holders of the Class A Shares, the Class B Shares and the Class C Shares
shall receive the consideration proposed in such Replicated Change of Control for the Class A Shares, the Class B Shares and the Class C Shares, as applicable, and shall not receive the consideration provided for under
Section D.1(e) of Article Fourth of the Charter for a Charter Change of Control. 
 (A)
If the requisite shareholders, except for the holders of Class C Shares representing a majority of the issued and outstanding Class C Shares, approve a Non-Cash Change of Control as a Replicated Change of Control pursuant to
Section 3.6(h)(i), then the Company nevertheless may engage in such Non-Cash Change of Control and the holders of the Class A Shares and the Class B Shares shall receive the consideration proposed in the Replicated Change of Control
for the Class A Shares and the Class B Shares, as applicable, and shall not receive the consideration provided for under Section D.1(e) of Article Fourth of the Charter for a Charter Change of Control, and the holders of the Class
C Shares shall receive the consideration provided for the Class C Shares under Section D.1(e) of Article Fourth of the Charter for a Charter Change of Control (other than a Replicated Change of Control), provided that such
Non-Cash Change of Control must be a bona fide transaction with a third party that is not an Affiliate of the Company (other than Kinder and his Affiliates (excluding any Person who is an Affiliate of Kinder solely as a result of such Person’s
relationship with the Company and its Subsidiaries)) or any Investor Shareholder; provided, further, that such transaction may be with or involve KMP, KMR, EPB or their respective Subsidiaries or controlled Affiliates. 

(B) The Company shall provide written notice to all Class C Shareholders of its intent to pursue a Non-Cash Change of
Control pursuant to Section 3.6(h)(i)(A). If the holders of Class C Shares representing a majority of the issued and outstanding Class 

  
 8 








 
C Shares elect to participate in such Non-Cash Change of Control by notifying the Company in writing within ten (10) calendar days after receipt of the Company’s notice, the holders of
the Class C Shares shall receive the consideration proposed in such Non-Cash Change of Control for the Class C Shares and shall not receive the consideration provided for under Section D.1(e) of Article Fourth of the Charter
for a Charter Change of Control. 
 (ii) Regardless of whether or not the holders of Class B Shares and/or the
holders of Class C Shares have approved a Non-Cash Change of Control as a Replicated Change of Control pursuant to Section 3.6(h)(i), (A) the Investor Shareholders holding Voting Securities representing a majority of the Total
Voting Power then held by the Investor Shareholders that continue to hold Class A Shares and (B) Kinder (so long as Kinder (together with his Permitted Transferees) continues to hold Class A Shares), may agree in writing that such
Non-Cash Change of Control shall not be subject to the requirement to be a Replicated Change of Control so long as such Non-Cash Change of Control (x) is a bona fide transaction with a third party that is not an Affiliate of the Company (other
than Kinder and his Affiliates (excluding any Person who is an Affiliate of Kinder solely as a result of such Person’s relationship with the Company and its Subsidiaries)) or any Investor Shareholder; provided, further, that such
transaction may be with or involve KMP, KMR, EPB or their respective Subsidiaries or controlled Affiliates and (y) provides for the holders of the Class A Shares, the Class B Shares and the Class C Shares to receive the consideration
provided for under Section D.1(e) of Article Fourth of the Charter for a Charter Change of Control (other than a Replicated Change of Control). 
 (iii) The requirements of this Section 3.6(h) shall be in addition to any other approvals required by the Charter, the Bylaws or applicable law for a Non-Cash Change of Control. 

(i) Kinder agrees that, from the date of this Agreement until May 31, 2015, Kinder shall notify the Eligible Investor Shareholders
prior to Kinder (including his Permitted Transferees and, to the extent of his control, his Affiliates), directly or indirectly, effecting, or offering or proposing (whether publicly or otherwise) to effect, any acquisition of beneficial ownership
of any securities of the Company or any of its Subsidiaries that are publicly traded in a transaction or a series of related transactions involving a value in excess of $50,000,000. 

(j) The Company shall make one-time compensatory cash payments in an aggregate amount of approximately $100,000,000 to certain
non-executive management employees of the Company and its Subsidiaries, which one-time payments shall be in addition to the Company’s usual periodic cash compensatory payments made to employees. The employee payees of such one-time payments and
amount payable to 

  
 9 








 
each such employee payee shall be at the discretion of the Chief Executive Officer of the Company and the timing of such one-time payments shall be at the discretion of the Company’s
management; provided, that such one-time payments shall be made reasonably promptly after the payment of the Company’s initial quarterly dividend following the consummation of the IPO; provided, further, that any such one-time
payments to holders of Class B Shares or Class C Shares pursuant to this Section 3.6(j) shall be subject to approval by the board of directors pursuant to Section 3.12(i) of the Bylaws. 

(k) Without limitation to any other rights granted to the Investor Shareholders by the Company pursuant to the Charter, Bylaws, this
Agreement, or pursuant to applicable law, the Company shall provide each Investor Shareholder that holds Class A Shares or Related Shares or its designated agents or representatives with the right to inspect, audit, excerpt or copy the
Company’s share registry, share transfer books and other documents and information related to the ownership of the Class A Shares, the Class B Shares, the Class C Shares and the Class P Shares as such Investor Shareholder may request,
including the Phantom Class B Shares and Phantom Class C Shares of the Canadian Participants as well as the Class B Shares and Class C Shares held by the Canadian Plan Entity that correspond to such Phantom Class B Shares and Phantom Class C Shares,
in order to confirm ownership calculations, in each case at such times during reasonable business hours as such Investor Shareholders shall reasonably request. 
 (l) In the event of an All Cash Tender Offer or a Non-Cash Tender Offer (each, a “Tender Offer”), the parties agree as follows: 

(i) If such Tender Offer permits delivery of shares via a notice of guaranteed delivery, each Class A Shareholder
intending to tender Class P Shares received upon a Voluntary Conversion of such Class A Shareholder’s Class A Shares into such Tender Offer shall use commercially reasonable efforts (and the Company shall reasonably cooperate in such
efforts) to tender such Class P Shares into such Tender Offer via a notice of guaranteed delivery; provided, that tendering via a notice of guaranteed delivery does not impair, prejudice or otherwise adversely affect such Class A
Shareholder’s ability to participate in or otherwise receive the benefits of such Tender Offer. If such Class A Shareholder does tender Class P Shares via a notice of guaranteed delivery pursuant to this Section 3.6(l)(i), such
Class A Shareholder shall issue a Conversion Notice to the Company and the Transfer Agent at a time as close as practicable to the then-current expiration time of such Tender Offer to ensure sufficient time for the conversion of such
Class A Shares and the Transfer of such Class P Shares in accordance with the terms of such notice of guaranteed delivery and such Tender Offer, and, upon receipt of such Conversion Notice, the Company shall use its reasonable best efforts to
ensure that such conversion and such Transfer occur in accordance with the terms of such notice of guaranteed delivery and such Tender Offer. 

  
 10 









 (ii) In the event that such Tender Offer does not permit delivery of shares
via a notice of guaranteed delivery, each Class A Shareholder intending to tender Class P Shares received upon a Voluntary Conversion of such Class A Shareholder’s Class A Shares into such Tender Offer and the Company shall use
its commercially reasonable efforts to enable such Class A Shareholder to tender Class P Shares into such Tender Offer while preserving the relative economic rights (in a manner consistent with the intent and purpose of the Charter, the Bylaws
and this Agreement) of the holders of Class A Shares, Class B Shares and Class C Shares to distributions and to Class P Shares (and distributions thereon) issuable upon conversion of their Class A Shares, Class B Shares and Class C Shares
during the pendency of such Tender Offer. The parties acknowledge that there may be delays (which each of the parties shall use its reasonable best efforts to cooperate in keeping as short as practicable) in calculating the amount of distributions
payable to the holders of Class A Shares, Class B Shares, Class C Shares and Class P Shares pursuant to Section C of Article Fourth of the Charter (in a manner consistent with the intent and purpose of the Charter, the Bylaws and
this Agreement), or the number of Class P Shares issuable upon conversion of Class A Shares, Class B Shares and Class C Shares pursuant to Section D of Article Fourth of the Charter (in a manner consistent with the intent and
purpose of the Charter, the Bylaws and this Agreement), in each case during the pendency of such Tender Offer, which may result in delays (which each of the parties shall use its reasonable best efforts to cooperate in keeping as short as
practicable) in the payment of such distributions or the delivery of such Class P Shares to holders of Class A Shares, Class B Shares or Class C Shares. Without limiting the generality of the foregoing, the parties shall, to the extent
necessary or appropriate to achieve the purpose and intent of this Section 3.6(l)(ii), consider in good faith consenting to reasonable escrow mechanics (e.g., that contemplate the temporary placement of such distributions or such Class P
Shares in escrow), which consents shall not be unreasonably withheld or delayed; provided, that each of the parties shall use its reasonable best efforts to cooperate in keeping any such escrow period as short as practicable; provided,
further, that nothing in this Section 3.6(l)(ii) shall be interpreted to require any such Class A Shareholder to take, or refrain from taking, any action to the extent taking (or not taking) such action would impair, prejudice or
otherwise adversely affect such Class A Shareholder’s ability to participate in or otherwise receive the benefits of such Tender Offer. 
 (iii) Terms used in this Section 3.6(l) but not defined in this Agreement shall have the meanings given such terms in the Charter. 

(m) The Canadian Plan Entity shall be established in connection with 

  
 11 









 
the Company’s administration of the Canadian Plan for the Canadian Participants. Each Phantom Class B Share shall provide for payments, if any, in gross amounts and gross value no greater
than (and shall have vesting and forfeiture provisions upon termination of employment no more favorable to the Canadian Participant holding such Phantom Class B Share than), the Class B Share held by the Canadian Plan Entity to which such Phantom
Class B Share corresponds (including, for the avoidance of doubt, Class P Shares, if any, received upon automatic conversion of such corresponding Class B Share); provided, that, subject to the foregoing limitations and to the extent that the
Company in good faith determines is necessary or appropriate to mitigate any negative consequences to either the Company or holders of Phantom Class B Shares, the Company may elect to make distributions in cash in lieu of Class P Shares received in
respect of the automatic conversion of Class B Shares held by the Canadian Plan Entity that would otherwise be distributable as a result of such automatic conversion. Each Phantom Class C Share shall provide for payments, if any, in gross amounts
and gross value no greater than the Class C Share held by the Canadian Plan Entity to which such Phantom Class C Share corresponds (including, for the avoidance of doubt, Class P Shares, if any, received upon automatic conversion of such
corresponding Class C Share); provided, that, subject to the foregoing limitations and to the extent that the Company in good faith determines is necessary or appropriate to mitigate any negative consequences to either the Company or holders
of Phantom Class C Shares, the Company may elect to make distributions in cash in lieu of Class P Shares received in respect of the automatic conversion of Class C Shares held by the Canadian Plan Entity that would otherwise be distributable as a
result of such automatic conversion. Each Phantom Class B Share and each Phantom Class C Share shall have exactly one corresponding Class B Share and Class C Share, respectively, in each case held by the Canadian Plan Entity, and the automatic
conversion of any such corresponding Class B Share or Class C Share into Class P Shares shall result in the cancellation of the applicable Phantom Class B Share or Phantom Class C Share. In the event that the Company elects to make a distribution in
cash in lieu of Class P Shares pursuant to the foregoing provisos of this Section 3.6(m), then the Company shall take all action necessary or appropriate for such Class P Shares to be immediately cancelled. All Phantom Class B Shares and
Phantom Class C Shares shall at all times be held only by the Canadian Participants. Amendments, modifications or waivers of any provision of any organizational or other governing document of the Canadian Plan Entity or any governing or similar
document of the Canadian Plan, in each case, shall require, in addition to any required approvals, the approval of (i) Kinder (so long as Kinder (together with his Permitted Transferees) owns at least 1.0% of the Total Voting Power),
(ii) the Investor Shareholders holding Voting Securities representing a majority of the Total Voting Power then held by the Investor Shareholders (so long as the Investor Shareholders own at least an aggregate amount of 1.0% of the Total Voting
