shall cause CCE Holdings to contribute to Merger Sub the funds, if any, CCE Holdings receives pursuant to the Citrus Transfer (not to exceed $1,450,000,000) in exchange for an equity interest in Merger Sub proportionate to its Deemed Share. Such

shall be cancelled and retired and shall cease to exist, and no consideration shall be delivered in exchange for such cancellation and retirement. From and after the Effective Time, all certificates representing the capital stock of Merger Sub held

Section 5.6(a) (or appropriate alternative arrangements shall be made by Parent if uncertificated Common Units will be issued) and an amount of cash sufficient (when combined with the Company Cash Funds) to effect the delivery of the Merger
Consideration to the holders of Company Common Shares (other than Cancelled Shares and any Dissenting Shares) and (ii) the Company shall cause CCE Holdings to deposit the Company Cash Funds with the Exchange Agent. Following the Effective Time,

comply with its obligations under this Section 5.19 in all material respects, the consummation of the Citrus Transfer shall not otherwise be a condition to consummation of the Merger.” 

Section 1.9. Addition of Section 5.20. Article V of the Agreement is hereby amended to add the following after
Section 5.19 and before Article VI: 
 “Section 5.20 PEPL Holdings Guarantee. 

(a)        If a request in writing is made by Parent to the Company, the Company shall use its
reasonable best efforts to cause to be prepared and filed with the SEC a Registration Statement on Form S-1 or such other registration form as may be appropriate (“Guarantor Registration Statement”) for the purpose of
registering the guarantee (the “Guarantee”) by PEPL 

  
 3 

 
Holdings, LLC, a Delaware limited liability company and indirect subsidiary of the Company (“PEPL Holdings”), of a new and separate borrowing by ETP that will be used by ETP
exclusively to pay the cash consideration under the ETP Merger Agreement (the “ETP Debt”), as promptly as reasonably practicable and in any event no later than 45 days after such request. Notwithstanding anything to the contrary
contained herein, the Guarantee shall not be effective until immediately prior to the Effective Time and shall be nonrecourse to Southern Union. The Company shall use its reasonable best efforts to cause the Guarantor Registration Statement to be
declared effective under the Securities Act as promptly as reasonably practicable after such filing and to keep the Guarantor Registration Statement effective as long as necessary to consummate the offering of the Guarantee and the other
transactions involving the ETP Debt. The Company shall also use its reasonable best efforts to take or cause to be taken any action required to be taken under any applicable state or provincial securities laws in connection with the issuance of the
Guarantee, and the Company shall furnish or cause to be furnished all information concerning the Company, PEPL Holdings or their respective affiliates as may be reasonably requested in connection with any such action. No filing of, or amendment or
supplement to, the Guarantor Registration Statement will be made by PEPL Holdings without Parent’s prior consent (which consent shall not be unreasonably withheld, delayed or conditioned) and without providing Parent a reasonable opportunity to
review and comment thereon. The Company will advise Parent promptly after it or PEPL Holdings receives oral or written notice of the time when the Guarantor Registration Statement has become effective or any supplement or amendment has been filed,
the issuance of any stop order, the suspension of the qualification of the Guarantee for offering or sale in any jurisdiction, or any oral or written request by the SEC for amendment of the Guarantor Registration Statement or comments thereon and
responses thereto or requests by the SEC for additional information, and will promptly provide Parent with copies of any written communication from the SEC or any state securities commission. If at any time prior to the Effective Time any
information relating to PEPL Holdings, or any of its affiliates, officers or directors, is discovered by the Company or PEPL Holdings which should be set forth in an amendment or supplement to the Guarantor Registration Statement, so that such
document would not include any misstatement of a material fact or omit to state any material fact necessary to make the statements therein, in light of the circumstances under which they were made, not misleading, the Company shall promptly notify
Parent and the Company shall cause to be promptly filed with the SEC an appropriate amendment or supplement describing such information and, to the extent required by law, disseminate such information to the holders of the Guarantee. Parent shall,
and shall use its reasonable best efforts to cause its affiliates including ETP and its and their respective officers, employees, agents and representatives, to provide to the Company cooperation reasonably requested by the Company that is necessary
or reasonably required in connection with the Guarantor Registration Statement, including without limitation, purchase price fair value allocation adjustment information related to PEPL Holdings and its affiliates. None of the information provided
by Parent or any of its affiliates including ETP for inclusion or incorporation by reference in the Guarantor Registration Statement to be filed with the SEC in connection with the Guarantee will, at the time the Guarantor Registration Statement
becomes effective under the Securities Act, contain any untrue statement of a material fact or omit to state any material fact required to be stated therein or necessary to make the statements therein not misleading. Notwithstanding the foregoing
provisions of this Section 5.20(a), no representation or warranty is made by Parent with respect to information or statements made or 

  
 4 

 
incorporated by reference in the Guarantor Registration Statement that were not supplied by or on behalf of Parent or any of its affiliates including ETP. 

(b)        If, in lieu of one or more offerings of ETP Debt that are registered under the
Securities Act, ETP elects to issue the ETP Debt in one or more offerings exempt from registration under the Securities Act (including sales under Rule 144A of the Securities Act) (collectively, the “Exempt Offerings”), then the
Company will cause PEPL Holdings to provide ETP with such information regarding PEPL Holdings and its affiliates as may be necessary or appropriate to facilitate the Exempt Offerings, including information regarding the business, financial
condition, results of operations and management of PEPL Holdings and its affiliates, together with financial statements of PEPL Holdings that would customarily be included in a Rule 144A offering memorandum. If at any time prior to the closing of an
Exempt Offering any information relating to PEPL Holdings, or any of its affiliates, officers or directors, is discovered by the Company or PEPL Holdings which should be set forth in an amendment or supplement to the offering document relating to
such Exempt Offering, so that such document would not include any misstatement of a material fact or omit to state any material fact necessary to make the statements therein, in light of the circumstances under which they were made, not misleading,
the Company shall promptly provide Parent with such information for inclusion in an amendment or supplement to such document.” 
 (c)        The reasonable out-of-pocket costs and expenses of such cooperation and actions under this Section 5.20 shall be borne by the Parent. Parent shall
indemnify the Company, PEPL Holdings and their affiliates and their respective officers, directors or managers against any liabilities and expenses (including attorneys’ fees) resulting from any of the actions under this Section 5.20,
other than with respect to any liabilities and expenses resulting from misstatements of a material fact by PEPL Holdings and its affiliates, or omissions to state any material facts necessary to make the statements provided by PEPL Holdings and its
affiliates, in light of the circumstances under which they were made, not misleading. Notwithstanding anything to the contrary contained in this Agreement, the Company shall not be deemed to be in breach of the covenants set forth in this
Section 5.20 so long as it has acted in good faith to comply with its obligations set forth herein and, for the avoidance of doubt, the filing or effectiveness of the Guarantor Registration Statement shall not otherwise be a condition to
consummation of the Merger.
