 AGREEMENT 

NOW, THEREFORE, in consideration of the foregoing and the mutual covenants and agreements herein contained, and intending to be legally bound
hereby, the Parties hereby agree as follows: 
 1.    Defined Terms. The following capitalized terms, as used in
this Agreement, shall have the meanings set forth below. Capitalized terms used but not defined in this Agreement shall have the meanings ascribed to them in the Merger Agreement. 

“Covered Units” means TE’s Existing Units, together with any Partnership Common Units that TE becomes the Record Holder
or beneficial owner of on or after the date hereof. 
 “Proxy Designee” means a Person designated by the Partnership
Conflicts Committee by written notice to each of the Parties, which notice may simultaneously revoke the designation of any Person as a Proxy Designee. 






 “Record Holder” has the meaning ascribed thereto in the TEP Partnership
Agreement. 
 “Transfer” means, directly or indirectly, to sell, transfer, assign, pledge, hypothecate, encumber or
similarly dispose of (by merger (including by conversion into securities or other consideration), by tendering into any tender or exchange offer, by testamentary disposition, by operation of law or otherwise), either voluntarily or involuntarily, or
to enter into any contract, option or other arrangement or understanding with respect to the voting of or sale, transfer, assignment, pledge, encumbrance or similar disposition of (by merger, by tendering into any tender or exchange offer, by
testamentary disposition, by operation of law or otherwise); provided, however, that for the purposes of clarification, a “Transfer” shall not include any existing or future pledges or security interests issued by TE (or the
foreclosure thereof) in connection with a bona fide loan, indenture or other contract for indebtedness.  

2.    Agreement to Vote in Favor of Merger. Prior to the Termination Date (as defined herein), TEGP and TE
irrevocably and unconditionally agree that, at any meeting of the limited partners of the Partnership, however called, whether annual or special and whether or not an adjourned or postponed meeting (or in connection with any written consent of the
limited partners of the Partnership), TE shall, and TEGP shall cause TE to, (a) appear at such meeting or otherwise cause the Covered Units to be counted as present thereat for purposes of establishing a quorum and (b) vote, or cause to be
voted, at such meeting (or validly execute and return and cause consent to be granted with respect to), all Covered Units (in all manners and by each applicable class) (i) in favor of the Merger Agreement and the Transactions, including, for
the avoidance of doubt, the Merger, and any other matters required to be approved by the holders of Partnership Common Units in connection with the Transactions, and (ii) against (A) any Acquisition Proposal, including any Superior Proposal,
and (B) any action that could reasonably be expected to impede, interfere with, delay, postpone or materially adversely affect the Merger, the Merger Agreement or any of the Transactions or the matters contemplated by this Agreement. If TE is
the beneficial owner, but not the Record Holder, of any Covered Units, TE agrees to take all actions necessary to cause the Record Holder and any nominees to vote (or grant a consent with respect to) all of such Covered Units in accordance with this
Section 2. Except as otherwise set forth in or contemplated by this Agreement, TE may vote the Covered Units in its discretion on all matters submitted for the vote of holders of Partnership Common Units or in connection with any
written consent of the holders of Partnership Common Units in a manner that is not inconsistent with the terms of this Agreement. 

3.    Grant of Irrevocable Proxy; Appointment of Proxy. 

(a)    FROM AND AFTER THE DATE HEREOF UNTIL THE TERMINATION DATE, TE HEREBY IRREVOCABLY AND UNCONDITIONALLY GRANTS TO, AND
APPOINTS, CHRISTOPHER R. JONES, AND ANY OTHER PROXY DESIGNEE, EACH OF THEM INDIVIDUALLY, AS TE’S PROXY AND ATTORNEY-IN-FACT (WITH FULL POWER OF SUBSTITUTION)
TO VOTE (OR EXERCISE A WRITTEN CONSENT WITH RESPECT TO) THE COVERED UNITS SOLELY IN ACCORDANCE WITH SECTION 2. THIS PROXY IS IRREVOCABLE (UNTIL THE TERMINATION DATE AND EXCEPT AS TO ANY PROXY DESIGNEE WHOSE DESIGNATION AS A
PROXY DESIGNEE IS REVOKED BY THE PARTNERSHIP CONFLICTS COMMITTEE) AND COUPLED WITH AN INTEREST, AND TE WILL TAKE SUCH FURTHER ACTION OR EXECUTE SUCH OTHER INSTRUMENTS 

  
 2 







 
AS MAY BE NECESSARY TO EFFECTUATE THE INTENT OF THIS PROXY AND HEREBY REVOKES ANY OTHER PROXY PREVIOUSLY GRANTED BY TE WITH RESPECT TO THE COVERED UNITS (AND TE HEREBY REPRESENTS TO THE
PARTNERSHIP THAT ANY SUCH OTHER PROXY IS REVOCABLE). 
 (b)    The proxy granted in this Section 3
shall automatically expire upon the termination of this Agreement. 
 4.    Prohibition on Transfers and Certain
Other Actions. Neither TEGP nor TE shall, and TEGP shall cause TE and each other member of the TEGP Group not to, without the prior written consent of the Partnership Conflicts Committee, in any manner: 

(a)    Transfer, or enter into any contract, option, agreement or other arrangement or understanding with respect to the
Transfer of, any of the Covered Units or any other equity securities in the Partnership held, directly or indirectly, by any member of the TEGP Group or beneficial ownership or voting power thereof or therein (including by operation of law), except
to the extent permitted by the Merger Agreement; 
 (b)    knowingly take any action that would make any representation
or warranty of TE contained herein untrue or incorrect or have the effect of preventing or disabling TE from performing its obligations under this Agreement; or 

(c)    propose, agree to, promote, solicit or publicly announce its willingness to undertake or support any of the
foregoing. 
 5.    No Inconsistent Agreements. Except as contemplated by this Agreement, TE (i) has not
entered into, and shall not enter into at any time prior to the Termination Date, any voting agreement or voting trust with respect to any Covered Units and (ii) has not granted, and shall not grant at any time prior to the Termination Date, a
proxy or power of attorney with respect to any Covered Units, in either case, which is inconsistent with TE’s obligations pursuant to this Agreement.

occurrence of a Partnership Adverse Recommendation Change made by the Partnership Conflicts Committee, (c) the termination of the Merger Agreement in accordance with its terms and (d) the mutual written agreement of the Parties to
terminate this Agreement approved by the TEGP Management Board in the case of TEGP or TE and by the Partnership Conflicts Committee in the case of the Partnership (such earliest date being referred to herein as the “Termination
Date”); provided, however, that the provisions set forth in Section 11, Section 15, Section 17, Section 21 and
Section 23 shall survive the termination of this Agreement; and provided, further, that any liability incurred by any Party as a result of a breach of a term or condition of this Agreement prior to such

subject matter hereof and supersedes all prior agreements and understandings, both written and oral, among the Parties with respect to the subject matter hereof. 

15.    Governing Law. This Agreement shall be subject to and governed by the laws of the State of Delaware, without
regard to principles of conflicts of laws. With respect to any action, suit or proceeding arising out of or relating to this Agreement, each Party agrees that Section 8.3 of the Merger Agreement shall govern and makes the acknowledgements
provided therein. 
 16.    Specific Performance. The Parties agree that irreparable damage would occur and that
the Parties would not have any adequate remedy at law in the event that any of the provisions of this Agreement were not performed in accordance with their specific terms or were otherwise breached and it is accordingly agreed that the Parties shall
be entitled to an injunction or injunctions to prevent breaches of this Agreement and to enforce specifically the terms and provisions of this Agreement, in each case, in accordance with Section 16, this being in addition
to any other remedy to which they are entitled at law or in equity. Each Party further agrees that no Party shall be required to obtain, furnish or post any bond or similar instrument in connection with or as a condition to obtaining any remedy

their respective permitted successors and assigns, but neither this Agreement nor any of the rights, benefits or obligations hereunder shall be assigned or transferred, by operation of law or otherwise. Nothing in this Agreement, express or implied,

 19.    Severability. If any provision of this Agreement is rendered or
declared illegal or unenforceable by reason of any existing or subsequently enacted legislation or by decree of a court of last resort, the Parties shall promptly meet and negotiate substitute provisions for those rendered or declared illegal or
unenforceable, but all of the remaining provisions of this Agreement shall remain in full force and effect, so long as the economic or legal substance of the Transactions are not affected in any manner materially adverse to any Party. 

20.    Multiple Counterparts. This Agreement may be executed in any number of counterparts, each of which shall be
deemed an original, but all of which together shall constitute one and the same instrument. Signatures to this Agreement transmitted by facsimile transmission, by electronic mail in “portable document format” (“.pdf”) form, or by

21.    Interpretation. It is expressly agreed by the Parties that this Agreement shall not be construed against any
Party, and no consideration shall be given or presumption made, on the basis of who drafted this Agreement or any provision hereof or who supplied the form of this Agreement. Each Party agrees that it has exercised business discretion in negotiating
this Agreement and this Agreement correctly reflects its understanding of the matters set forth herein and, therefore, waives the application of any law or rule of construction providing that ambiguities in an agreement or other document will be
construed against the Party drafting such agreement or document. 
 22.    Action by the Partnership. Any
consent, approval, decision or waiver that is required to be given or made, or that may be given or made, by the Partnership with respect to the matters set forth herein shall be given or made by the Partnership Conflicts Committee, unless it is has
expressly waived in writing its right to give or make such consent, approval, decision or waiver. 
 23.    Non-Recourse. No past, present or future director, officer, employee, incorporator, member, partner, stockholder, agent, attorney, representative or affiliate of any Party or any of their respective Affiliates
(unless such Affiliate is expressly a Party) shall have any liability (whether in contract or in tort) for any obligations or liabilities of such Party arising under, in connection with or related to this Agreement; provided, however,
that nothing in this Section 23 shall limit any liability of the Parties to this Agreement for breaches of the terms and conditions of this Agreement.
