(“Guarantor”). The Support Provider, Sunoco LP and Guarantor may hereinafter be referred to individually as a “Party” or collectively as the “Parties.” 

PRELIMINARY STATEMENTS: 

A. Sunoco, LLC, a Delaware limited liability company (“Sunoco LLC”), Sunoco, Inc., a Pennsylvania corporation, Guarantor,
Sunoco GP LLC, a Delaware limited liability company, and Sunoco LP, and, solely for limited purposes, Energy Transfer Partners, L.P., a Delaware limited partnership (“ETP”), have entered into that certain Contribution Agreement,
dated as of November 15, 2015, as amended and supplemented (the “Contribution Agreement”), pursuant to which Guarantor has agreed to contribute to Sunoco LP (i) 68.42% of the membership interests in Sunoco LLC and
(ii) 100% of the membership interests in Sunoco Retail LLC, a Pennsylvania limited liability company (the “Contribution”). 

B. In connection with and in order to facilitate the Contribution, Sunoco LP entered into a $2.035 billion Senior Secured Term Loan Agreement
dated March 31, 2016 (the “Term Loan Facility” and the debt of Sunoco LP evidenced by such Term Loan Facility, the “Supported Debt”). 

C. Pursuant to the terms of the Contribution Agreement, at the closing of the Contribution on the date hereof, (i) Sunoco LP transferred
to the Support Provider for the benefit of Guarantor, in partial consideration for the Contribution, $2,199,999,979.66 in cash, financed in part from the proceeds of the Supported Debt (the “Sunoco LP Distribution”), and
(ii) Guarantor executed and delivered a guarantee dated as of even date herewith, providing for a guarantee of collection (but not of payment) for the principal amount due under the Term Loan Facility (the “ETP Retail Holdings
Guarantee”), a copy of which is attached hereto as Exhibit A. 
 D. Concurrently with the execution of this Agreement,
Guarantor is treated as distributing to the Support Provider a portion of the Sunoco LP Distribution equal to $1,988,799,981.61 (the “R&M Distribution” and the proportion of the total Sunoco LP Distribution reflected by such
R&M Distribution, equal to 90.4%, the “R&M Distribution Percentage”). Accordingly, in consideration of the R&M Distribution, the Support Provider desires to enter into this Agreement to provide support to Guarantor in
furtherance of the ETP Retail Holdings Guarantee in support of the Supported Debt, on the terms and subject to the conditions set forth herein. 

E. Sunoco LP, the Support Provider and Guarantor desire to enter into this Agreement and be bound by the terms and conditions set forth

 1. Support. Subject to the terms and conditions of this Agreement, including but
not limited to Sections 2 and 3 below, the Support Provider hereby provides support to Guarantor and agrees to contribute cash to Guarantor in such amounts as necessary to guarantee collection of the aggregate principal amount of
the Supported Debt pursuant to the ETP Retail Holdings Guarantee. Notwithstanding anything herein to the contrary, the obligations of the Parties under this Agreement are obligations solely of the Parties and do not constitute a debt or obligation
of (and no recourse shall be made with respect to) ETP, any of its affiliates (other than the Parties hereto), or any shareholder, partner, member, officer, director or employee of ETP or such affiliates (collectively, the “Non-Recourse
Parties”). No action under or in connection with this Agreement shall be brought against any Non-Recourse Party, and no judgment for any deficiency upon the obligations hereunder shall be obtainable against any Non-Recourse Party. 

2. Support Payment Conditions. Notwithstanding any other term or condition of this Agreement to the contrary, the Support
Provider shall be obligated to make contributions of cash to Guarantor pursuant to this Agreement to enable Guarantor to pay any and all amounts of the Supported Debt due and payable pursuant to the terms and conditions of the ETP Retail Holdings
Guarantee. 
 3. Cap. Notwithstanding any other term or condition of this Agreement to the contrary, it is agreed that the
Support Provider’s maximum liability under this Agreement with respect to the Supported Debt shall not exceed the R&M Distribution Percentage, multiplied by the positive difference (if any) between (i) the principal amount of Supported
Debt, minus (ii) the sum of (A) all payments of principal made by or on behalf of Sunoco LP in respect of such Supported Debt, plus (B) the fair market value of any property received or cash proceeds collected or any
consideration otherwise realized (including by way of set off) from or for the account of Sunoco LP pursuant to, or in connection with, the principal amount of Supported Debt, including, but not limited to, any property or cash proceeds collected or
realized from the exercise of any rights and remedies at law or in equity that the lenders of such Supported Debt may have against Sunoco LP or any collateral securing such Supported Debt, plus (C) any principal amount of such Supported
Debt which is forgiven or otherwise voluntarily compromised by the lenders of such Supported Debt (such amount, the “Support Cap”). 

The Support Provider shall have no obligation to make a payment hereunder with respect to any accrued and unpaid interest or any other costs,
fees, expenses, penalties, charges or other amounts of any kind whatsoever that may be owed by Guarantor or Sunoco LP, whether on or related to the Supported Debt or otherwise. 

4. Termination of Agreement. This Agreement shall remain in effect and will not terminate until the earlier to occur of

 5. Notices; Defenses; Etc. Sunoco LP and Guarantor hereby agree to provide the Support
Provider with notice promptly following any alleged default by Sunoco LP under the documents evidencing the Supported Debt or by Guarantor under the documents evidencing the ETP Retail Holdings Guarantee, and the Support Provider shall be entitled
to receive information regarding, and make reasonable requests for information with respect to, the actions the lenders 

  
 2 

 
of the Supported Debt have taken against Sunoco LP with respect to the Supported Debt or Guarantor with respect to the ETP Retail Holdings Guarantee. By entering into this Agreement, the Support
Provider is not waiving any defense, set-off or counterclaim available to Guarantor or Sunoco LP with respect to the Supported Debt nor is the Support Provider waiving its rights with respect to diligence, presentment, demand for performance, notice
of protest, notice of dishonor, default or non-payment, or notice of acceptance of this Agreement. 
 6. Covenants of Sunoco LP and
Guarantor. 
 (a) Repayment or Refinancing of Supported Debt. Without the prior written consent of the Support Provider,
Sunoco LP shall not be entitled to (i) repay any principal amount of the Supported Debt or (ii) refinance all or any portion of the Supported Debt, unless, in the case of (ii) above, Sunoco LP (x) simultaneously replaces the
Supported Debt with at least an equivalent amount of new indebtedness (such new indebtedness, the “Refinanced Supported Debt”) with substantially similar covenants providing for no earlier amortization of principal than the
amortization contemplated by the applicable maturity date of any Supported Debt (any such date, a “Maturity Date”), (y) permits Guarantor at its sole discretion to guarantee the Refinanced Supported Debt on the terms and
subject to the conditions set forth in the ETP Retail Holdings Guarantee and (z) permits Support Provider at its sole discretion to provide support to Guarantor in furtherance of the ETP Retail Holdings Guarantee of the Refinanced Supported

 (b) Actions Upon Maturity Date. Upon the Maturity Date for the

(c) Extinguishment of Supported Debt. Sunoco LP shall use commercially reasonable efforts to extinguish any applicable outstanding
Supported Debt on the Maturity Date. Guarantor shall release the Support Provider from any liability or obligation under this Agreement related to the Supported Debt on the applicable Maturity Date for such Supported Debt and shall enter into and
execute such documents and instruments as the Support Provider may reasonably request in order to evidence such release.

 7. Covenants of Support Provider. 

(a) Net Worth. Support Provider hereby represents to Guarantor and Sunoco LP that it will maintain net assets (excluding any interest
in Guarantor and Sunoco LP held by Support Provider) with a fair market value equal to or greater than the amount of the Support Cap and in the event Support Provider disposes of, transfers, or conveys any of its assets, except with respect to
distributions permitted in clause (b) below, it shall, if necessary, promptly replace such assets so as to have net assets (excluding any interest in Guarantor and Sunoco LP held by Support Provider) with a fair market value equal to or greater
than the amount of the Support Cap. Support Provider shall provide a certificate to Guarantor and the Administrative Agent (as defined in the Term Loan Facility) on an annual basis (beginning on the first anniversary of this Agreement and until the
Supported Debt has been paid in full) providing that it is in full compliance with this Section 7(a). 
 (b)
Distributions. Support Provider shall be entitled to make distributions of available cash with respect to its equity interests provided Support Provider shall not make a distribution of cash or property to the extent such distribution would
constitute a Fraudulent Conveyance (as defined in Section 10) in light of Support Provider’s obligations under this Agreement or otherwise impair Support Provider’s ability to satisfy its obligations under this Agreement. 

8. Covenants of the Parties to Maintain Tax Treatment. For so long as any ETP Retail Holdings Guarantee is outstanding, the
Parties hereto hereby agree that: 
 (a) At the Sunoco LP level, unless otherwise required by law, it is the intent of the Parties to treat
Guarantor as the sole partner bearing the economic risk of loss with respect to the Supported Debt pursuant to Treasury Regulation § 1.752-2; provided that, notwithstanding the foregoing, Sunoco LP shall not be required to take such
position in any taxable year to the extent Sunoco LP determines in good faith after consulting with tax counsel that such position is not supported by current law or actual facts and circumstances. 

(b) It is the intent of the Parties to treat the Sunoco LP Distribution as a distribution to Guarantor by Sunoco LP under Section 731 of
the Internal Revenue Code of 1986, as amended (the “Code”) to the extent allowable under Section 707 of the Code. Such Sunoco LP Distribution shall be treated as a “debt-financed transfer” under
Section 1.707-5(b) of the Treasury Regulations to the extent made out of proceeds of the Supported Debt. Neither Sunoco LP nor any partner of Sunoco LP shall take a position inconsistent with such treatment unless otherwise required by law;
provided that, notwithstanding the foregoing, Sunoco LP shall not be required to take such position in any taxable year to the extent Sunoco LP determines in good faith after consulting with tax counsel that such position is not supported by
current law or actual facts and circumstances. 
 (c) At the Guarantor level, unless otherwise required by law, it is the intent of the
Parties to treat the Support Provider as bearing the economic risk of loss with respect to the 

  
 4 

 
Supported Debt in an amount equal to the product of the R&M Distribution Percentage and the amount of the Supported Debt in accordance with Treasury Regulation § 1.752-2; provided that,
notwithstanding the foregoing, Guarantor shall not be required to take such position in any taxable year to the extent Guarantor determines in good faith after consulting with tax counsel that such position is not supported by current law or actual
facts and circumstances. 
 (d) It is the intent of the Parties to treat the R&M Distribution as a distribution to the Support Provider
by Guarantor under Section 731 of the Code to the extent allowable under Section 707 of the Code. Such R&M Distribution shall be treated as a “debt-financed transfer” under Section 1.707-5(b) of the Treasury Regulations
to the extent made out of proceeds of the Supported Debt. Neither Guarantor nor any partner of Guarantor shall take a position inconsistent with such treatment unless otherwise required by law; provided that, notwithstanding the foregoing, Guarantor
shall not be required to take such position in any taxable year to the extent Guarantor determines in good faith after consulting with tax counsel that such position is not supported by current law or actual facts and circumstances. 

(e) Neither Sunoco LP nor Guarantor shall (i) modify the ETP Retail Holdings Guarantee so as to eliminate or limit the ultimate recourse
liability of the Support Provider with respect to the Supported Debt, (ii) merge or consolidate with, or take any action that would cause, Guarantor to become a corporation for U.S. federal income tax purposes or (iii) except as required
by the Term Loan Facility, cause or permit any other corporation, partnership, person or entity to assume, guarantee, indemnify against or otherwise incur any liability with respect to any Supported Debt. 

(f) In the event a subsidiary of Sunoco LP that is regarded as separate and apart from Sunoco LP for U.S. federal income tax purposes becomes
a Subsidiary Guarantor (as such term is defined in the Term Loan Facility) of the Supported Debt or otherwise guarantees the Supported Debt, the Support Provider agrees to indemnify such subsidiary for any amounts that the subsidiary is required to
pay pursuant to its guarantee of the Supported Debt, on the same basis and subject to the same limits as with respect to the ETP Retail Holdings Guarantee. 

(g) In the event a partner of Sunoco LP guarantees or otherwise incurs any liability with respect to the Supported Debt, Support Provider
agrees to indemnify such partner for any amounts that the partner is required to pay pursuant to its guarantee or liability of the Supported Debt, on the same basis and subject to the same limits as with respect to the ETP Retail Holdings Guarantee.

 9. Waiver of Subrogation. The Support Provider irrevocably waives, relinquishes and renounces any right of subrogation,
contribution, indemnity, reimbursement or any claim whatsoever which the Support Provider may have against Sunoco LP or any other persons liable on the ETP Retail Holdings Guarantee or the Supported Debt. The Support Provider will not assert any
such claim against Sunoco LP or any other persons liable on the ETP Retail Holdings Guarantee or the Supported Debt, in any proceeding, legal or equitable, including any bankruptcy, insolvency or reorganization proceeding. This provision will inure
to the benefit of and will be enforceable by the Administrative Agent, the lenders of the Supported Debt, Sunoco LP and any such persons liable on the ETP Retail Holdings Guarantee or the Supported Debt, and their successors and assigns, including
any trustee in bankruptcy or debtor-in-possession. 

  
 5 

 10. Fraudulent Conveyance. Notwithstanding any provision of this Agreement to the
contrary, it is intended that this Agreement not constitute a Fraudulent Conveyance (as defined below). Consequently, the Support Provider agrees that if this Agreement would, but for the application of this sentence, constitute a Fraudulent
Conveyance, this Agreement shall be valid and enforceable only to the maximum extent that would not cause this Agreement to constitute a Fraudulent Conveyance, and this Agreement shall automatically be deemed to have been amended accordingly at all
relevant times. For purposes of this Section 10, the term “Fraudulent Conveyance” means a fraudulent conveyance under Section 548 of the United States Bankruptcy Code or a fraudulent conveyance or fraudulent
transfer under the provisions of any applicable fraudulent conveyance or fraudulent transfer law or similar law of any state, nation or other governmental unit, as in effect from time to time. 

11. Cumulative Rights; No Waiver. Each and every right granted to Support Provider hereunder or under any other document
delivered hereunder or in connection herewith, or allowed it by law or equity, shall be cumulative and may be exercised from time to time subject only to the limitations set forth in this Agreement. No failure on the part of Support Provider to
exercise, and no delay in exercising, any right shall operate as a waiver thereof, nor shall any single or partial exercise by Support Provider of any right preclude any other or future exercise thereof or the exercise of any other right. 

12. Amendments; Waivers. 

(a) Except as otherwise expressly set forth herein, this Agreement may not be modified, amended or waived except by an instrument or
instruments in writing signed by each of the Parties hereto. 
 (b) The Parties hereby agree that no provision of Section 1
hereof may be modified, amended or waived without the prior written consent of a majority of the lenders under the Term Loan Facility if such modification, amendment or waiver would materially and adversely reduce the benefits to such lenders of the
support contemplated by Section 1 hereof with respect to such Supported Debt. 
 13. Successors and Assigns. This
Agreement shall inure to the benefit of and be binding upon the parties hereto and their respective successors and assigns. Nothing in this Agreement shall prevent the Support Provider from merging or consolidating with or into any other person so
long as the surviving person agrees to be bound by the terms of this Agreement. 
 14. Third-Party Beneficiaries. This
Agreement is for the benefit only of the Support Provider, Sunoco LP, and Guarantor, the Administrative Agent, the lenders of the Supported Debt, and the subsidiaries of Sunoco LP described in Section 8(f) and is not intended to confer
upon any other third party any rights or remedies hereunder, and shall not be construed as for the benefit of any other third party. 
 15.
Notices. Any and all notices, requests or other communications hereunder shall be given in writing and delivered by: (a) regular, overnight, registered or certified mail (return receipt requested), with first class postage
prepaid; (b) hand delivery; (c) facsimile transmission; or (d) overnight courier service, if to the Support Provider, at the following address or facsimile number for the Support Provider:

obligations evidenced by bonds, debentures, notes or similar instruments, (C) all obligations under conditional sale or other title retention agreements relating to property or assets, (D) all obligations issued or assumed as the deferred
purchase price of property or 

  
 3 

 
services, (E) all guarantees of Indebtedness of others, (F) all capital lease obligations, (G) all obligations with respect to hedging and swap agreements, (H) the principal
component of all obligations, contingent or otherwise, as an account party in respect of letters of credit and (I) the principal component of all obligations in respect of bankers’ acceptances. 

7. Covenants of Support Provider. 

(a) Net Worth. Support Provider hereby represents to Guarantor and Sunoco LP that it will maintain net assets (excluding any interest
in Guarantor and Sunoco LP held by Support Provider) with a fair market value equal to or greater than the amount of the Support Cap and in the event Support Provider disposes of, transfers, or conveys any of its assets, except with respect to
distributions permitted in clause (b) below, it shall, if necessary, promptly replace such assets so as to have net assets (excluding any interest in Guarantor and Sunoco LP held by Support Provider) with a fair market value equal to or greater
than the amount of the Support Cap. Support Provider shall provide a certificate to Guarantor and the Administrative Agent (as defined in the Term Loan Facility) on an annual basis (beginning on the first anniversary of this Agreement and until the
Supported Debt has been paid in full) providing that it is in full compliance with this Section 7(a). 
 (b)
Distributions. Support Provider shall be entitled to make distributions of available cash with respect to its equity interests provided Support Provider shall not make a distribution of cash or property to the extent such distribution would
constitute a Fraudulent Conveyance (as defined in Section 10) in light of Support Provider’s obligations under this Agreement or otherwise impair Support Provider’s ability to satisfy its obligations under this Agreement. 

8. Covenants of the Parties to Maintain Tax Treatment. For so long as any ETP Retail Holdings Guarantee is outstanding, the
Parties hereto hereby agree that: 
 (a) At the Sunoco LP level, unless otherwise required by law, it is the intent of the Parties to treat
Guarantor as the sole partner bearing the economic risk of loss with respect to the Supported Debt pursuant to Treasury Regulation § 1.752-2; provided that, notwithstanding the foregoing, Sunoco LP shall not be required to take such
position in any taxable year to the extent Sunoco LP determines in good faith after consulting with tax counsel that such position is not supported by current law or actual facts and circumstances. 

(b) It is the intent of the Parties to treat the Sunoco LP Distribution as a distribution to Guarantor by Sunoco LP under Section 731 of
the Internal Revenue Code of 1986, as amended (the “Code”) to the extent allowable under Section 707 of the Code. Such Sunoco LP Distribution shall be treated as a “debt-financed transfer” under
Section 1.707-5(b) of the Treasury Regulations to the extent made out of proceeds of the Supported Debt. Neither Sunoco LP nor any partner of Sunoco LP shall take a position inconsistent with such treatment unless otherwise required by law;
provided that, notwithstanding the foregoing, Sunoco LP shall not be required to take such position in any taxable year to the extent Sunoco LP determines in good faith after consulting with tax counsel that such position is not supported by
current law or actual facts and circumstances. 

  
 4 

 (c) At the Guarantor level, unless otherwise required by law, it is the intent of the Parties to
treat the Support Provider as bearing the economic risk of loss with respect to the Supported Debt in an amount equal to the product of the Atlantic Distribution Percentage and the amount of the Supported Debt in accordance with Treasury Regulation
§ 1.752-2; provided that, notwithstanding the foregoing, Guarantor shall not be required to take such position in any taxable year to the extent Guarantor determines in good faith after consulting with tax counsel that such position is not
supported by current law or actual facts and circumstances. 
 (d) It is the intent of the Parties to treat the Atlantic Distribution as a
distribution to the Support Provider by the Guarantor under Section 731 of the Code to the extent allowable under Section 707 of the Code. Such Atlantic Distribution shall be treated as a “debt-financed transfer” under
Section 1.707-5(b) of the Treasury Regulations to the extent made out of proceeds of the Supported Debt. Neither Guarantor nor any partner of Guarantor shall take a position inconsistent with such treatment unless otherwise required by law;
provided that, notwithstanding the foregoing, Guarantor shall not be required to take such position in any taxable year to the extent Guarantor determines in good faith after consulting with tax counsel that such position is not supported by current
law or actual facts and circumstances. 
 (e) Neither Sunoco LP nor Guarantor shall (i) modify the ETP Retail Holdings Guarantee so as
to eliminate or limit the ultimate recourse liability of the Support Provider with respect to the Supported Debt, (ii) merge or consolidate with, or take any action that would cause, Guarantor to become a corporation for U.S. federal income tax
purposes or (iii) except as required by the Term Loan Facility, cause or permit any other corporation, partnership, person or entity to assume, guarantee, indemnify against or otherwise incur any liability with respect to any Supported Debt.

 (f) In the event a subsidiary of Sunoco LP that is regarded as separate and apart from Sunoco LP for U.S. federal income tax purposes
becomes a Subsidiary Guarantor (as such term is defined in the Term Loan Facility) of the Supported Debt or otherwise guarantees the Supported Debt, the Support Provider agrees to indemnify such subsidiary for any amounts that the subsidiary is
required to pay pursuant to its guarantee of the Supported Debt, on the same basis and subject to the same limits as with respect to the ETP Retail Holdings Guarantee. 

(g) In the event a partner of Sunoco LP guarantees or otherwise incurs any liability with respect to the Supported Debt, the Support Provider
agrees to indemnify such partner for any amounts that the partner is required to pay pursuant to its guarantee or liability of the Supported Debt, on the same basis and subject to the same limits as with respect to the ETP Retail Holdings Guarantee.

 9. Waiver of Subrogation. The Support Provider irrevocably waives, relinquishes and renounces any right of subrogation,
contribution, indemnity, reimbursement or any claim whatsoever which the Support Provider may have against Sunoco LP or any other persons liable on the ETP Retail Holdings Guarantee or the Supported Debt. The Support Provider will not assert any
such claim against Sunoco LP or any other persons liable on the ETP Retail Holdings Guarantee or the Supported Debt, in any proceeding, legal or equitable, including any bankruptcy, insolvency or reorganization proceeding. This provision will inure
to the benefit of and will be enforceable by the Administrative Agent, the lenders of the Supported Debt, Sunoco LP and any such persons liable on the ETP Retail Holdings Guarantee or the Supported Debt, and their successors and assigns, including
any trustee in bankruptcy or debtor-in-possession.

 10. Fraudulent Conveyance. Notwithstanding any provision of this Agreement to the
contrary, it is intended that this Agreement not constitute a Fraudulent Conveyance (as defined below). Consequently, the Support Provider agrees that if this Agreement would, but for the application of this sentence, constitute a Fraudulent
Conveyance, this Agreement shall be valid and enforceable only to the maximum extent that would not cause this Agreement to constitute a Fraudulent Conveyance, and this Agreement shall automatically be deemed to have been amended accordingly at all
relevant times. For purposes of this Section 10, the term “Fraudulent Conveyance” means a fraudulent conveyance under Section 548 of the United States Bankruptcy Code or a fraudulent conveyance or fraudulent
transfer under the provisions of any applicable fraudulent conveyance or fraudulent transfer law or similar law of any state, nation or other governmental unit, as in effect from time to time. 

11. Cumulative Rights; No Waiver. Each and every right granted to Support Provider hereunder or under any other document
delivered hereunder or in connection herewith, or allowed it by law or equity, shall be cumulative and may be exercised from time to time subject only to the limitations set forth in this Agreement. No failure on the part of Support Provider to
exercise, and no delay in exercising, any right shall operate as a waiver thereof, nor shall any single or partial exercise by Support Provider of any right preclude any other or future exercise thereof or the exercise of any other right. 

12. Amendments; Waivers. 

(a) Except as otherwise expressly set forth herein, this Agreement may not be modified, amended or waived except by an instrument or
instruments in writing signed by each of the Parties hereto. 
 (b) The Parties hereby agree that no provision of Section 1
hereof may be modified, amended or waived without the prior written consent of a majority of the lenders under the Term Loan Facility if such modification, amendment or waiver would materially and adversely reduce the benefits to such lenders of the
support contemplated by Section 1 hereof with respect to such Supported Debt. 
 13. Successors and Assigns. This
Agreement shall inure to the benefit of and be binding upon the parties hereto and their respective successors and assigns. Nothing in this Agreement shall prevent the Support Provider from merging or consolidating with or into any other person so
long as the surviving person agrees to be bound by the terms of this Agreement. 
 14. Third-Party Beneficiaries. This
Agreement is for the benefit only of the Support Provider, Sunoco LP, and Guarantor, the Administrative Agent, the lenders of the Supported Debt, and the subsidiaries of Sunoco LP described in Section 8(f) and is not intended to confer
upon any other third party any rights or remedies hereunder, and shall not be construed as for the benefit of any other third party. 
 15.

 16. Separability. Should any clause,
sentence, paragraph, subsection or section of this Agreement be judicially declared to be invalid, illegal or unenforceable in any respect, such decision will not have the effect of invalidating or voiding the remainder of this Agreement, and the
part or parts of this Agreement so held to be invalid, illegal or unenforceable will be deemed to have been stricken herefrom, and the remainder will have the same force and effectiveness as if such stricken part or parts had never been included
herein. 
 17. Counterparts. This Agreement may be executed in any number of counterparts and by different Parties hereto in
separate counterparts, each of which when so executed shall be deemed to be an original and all of which taken together shall constitute one and the same agreement; signature pages may be detached from multiple separate counterparts and attached to

a single counterpart so that all signatures are physically attached to the same counterpart. Delivery of an executed signature page by facsimile or electronic transmission shall be as effective
as delivery of a manually executed counterpart.

for convenience of reference and are not intended to affect the interpretation of any provision of this Agreement. 
 19. Entire
Agreement. This Agreement constitutes the entire agreement of the Parties hereto with respect to the subject matter hereof and supersedes all prior agreements and understandings, oral or written, between the Parties related thereto. 

20. Governing Law. THIS AGREEMENT SHALL BE GOVERNED BY AND CONSTRUED IN ACCORDANCE WITH THE LAWS OF THE STATE OF NEW YORK
WITHOUT GIVING EFFECT TO APPLICABLE PRINCIPLES OF CONFLICTS OF LAWS TO THE EXTENT THE LAWS OF ANOTHER JURISDICTION WOULD BE REQUIRED THEREBY. 

21. Consent to Jurisdiction; Waiver of Jury Trial. The Parties irrevocably submit to the exclusive jurisdiction of any New York
State court or federal court of the United States of America sitting in New York County, and any appellate court from any thereof, for the purposes of any proceeding arising out of this Agreement or the transactions contemplated hereby (and each
agrees that no such proceeding relating to this Agreement or the transactions contemplated hereby shall be brought by it except in such courts). The Parties irrevocably and unconditionally waive (and agree not to plead or claim) any objection to the
laying of venue of any proceeding arising out of this Agreement or the transactions contemplated hereby in any New York State court or federal court of the United States of America sitting in New York County, and any appellate court from any
thereof, or that any such proceeding brought in any such court has been brought in an inconvenient forum. Each of the Parties also agrees that any final and non appealable judgment against a Party in connection with any proceeding shall be
conclusive and binding on such Party and that such award or judgment may be enforced in any court of competent jurisdiction, either within or outside of the United States. A certified or exemplified copy of such award or judgment shall be conclusive
evidence of the fact and amount of such award or judgment. TO THE FULLEST EXTENT PERMITTED BY APPLICABLE LAW, ANY ACTION OR PROCEEDING TO ENFORCE OR TO DEFEND ANY RIGHTS UNDER THIS AGREEMENT SHALL BE TRIED BEFORE A COURT AND NOT BEFORE A JURY.
