 Ladies and Gentlemen:

 Introductory. Genesis Energy, L.P., a Delaware limited partnership (the
“Partnership”), and Genesis Energy Finance Corporation, a Delaware corporation (“Finance Corp.” and, together with the Partnership, the “Issuers”), proposes to issue and sell to Merrill Lynch,
Pierce, Fenner & Smith Incorporated (“Merrill Lynch”) and the other several Initial Purchasers named in Schedule A (the “Initial Purchasers”), acting severally and not jointly, the respective amounts set
forth in such Schedule A of $250,000,000 aggregate principal amount of the Partnership’s 7 7/8% Senior Notes due 2018 (the “Notes”). Merrill Lynch has agreed to act as the representative of the several Initial Purchasers (the “Representative”) in connection with
the offering and sale of the Notes. 
 The Securities (as defined below) will be issued pursuant to an indenture, to be
dated as of November 18, 2010 (the “Indenture”), among the Issuers, the Guarantors (as defined below) and U.S. Bank National Association, as trustee (the “Trustee”). The Notes will be issued only in book-entry
form in the name of Cede & Co., as nominee of The Depository Trust Partnership (the “Depositary”) pursuant to a letter of representations, to be dated on or before the Closing Date (as defined in Section 2 hereof) (the
“DTC Agreement”), from the Issuers to the Depositary. 
 The holders of the Notes will be entitled to the
benefits of a registration rights agreement, to be dated as of November 18, 2010 (the “Registration Rights Agreement”), among the Issuers, the Guarantors and the Initial Purchasers, pursuant to which the Issuers and the
Guarantors will be required to file with the Commission (as defined below), under the circumstances set forth therein, (i) a registration statement under the Securities Act (as defined below) relating to another series of debt securities of the
Issuers with terms substantially identical to the Notes (the “Exchange Notes”) to be offered in exchange for the Notes (the “Exchange Offer”) and (ii) to the extent required by the Registration Rights
Agreement, a shelf registration statement pursuant to Rule 415 of the Securities Act relating to the resale by certain holders of the Notes, and in each case, to use its commercially reasonable efforts to cause such registration statements to be
declared effective. All references herein to the Exchange Notes and the Exchange Offer are only applicable if the Issuers and the Guarantors are in fact required to consummate the Exchange Offer pursuant to the terms of the Registration Rights
Agreement. 

  
 The payment of
principal of, premium, if any, and interest on the Notes will be fully and unconditionally guaranteed on a senior unsecured basis, jointly and severally by (i) the entities listed on the signature pages hereof as “Guarantors” and
(ii) any Subsidiary (as defined below) of the Partnership formed or acquired after the Closing Date that executes a supplemental indenture in accordance with the terms of the Indenture, and their respective successors and assigns (collectively,
the “Guarantors”), pursuant to their guarantees (the “Guarantees”). The Notes and the Guarantees related thereto are herein collectively referred to as the “Securities”; and the Exchange Notes and
the Guarantees related thereto are herein collectively referred to as the “Exchange Securities.” 
 On
October 22, 2010, the Partnership entered into a definitive purchase and sale agreement by and among the Partnership, Valero Energy Corporation, Valero Services, Inc., Valero Unit Investments, L.L.C., Genesis CHOPS I, LLC and Genesis CHOPS II,
LLC (the “Cameron Purchase Agreement”), pursuant to which the Partnership plans to, subject to the terms and conditions of the Cameron Purchase Agreement, consummate an acquisition from Valero Energy Corporation (the
“Cameron Acquisition”) of an indirect 50% equity interest in Cameron Highway Oil Pipeline Company (the “Cameron Subject Interest”) for aggregate consideration of approximately $330 million, subject to adjustment.
The net proceeds received from the sale of the Securities to the Initial Purchasers will be deposited into escrow, pursuant to an escrow agreement among the Partnership, the Trustee and U.S. Bank National Association, as escrow agent (the
“Escrow Agreement”), and will be released from escrow either at the closing of the Cameron Acquisition and used to finance in part the approximately $330 million purchase price and to pay related fees and expenses or if the Cameron
Purchase Agreement is terminated at any time on or prior to December 31 2010, all of the net proceeds will be used for redemption of all of the Securities at a redemption price equal to 100% of the aggregate issue price of the Securities, or,
if for purposes of complying with any necessary governmental or regulatory approval of the Cameron Acquisition, the closing of the Cameron Acquisition does not otherwise occur on or prior to February 28, 2011, all of the net proceeds will be
used for redemption of all of the Securities at a redemption price equal to 101% of the aggregate issue price of the Securities, in either case, plus any accrued and unpaid interest to, but not including, the redemption date. 

This Agreement, the Registration Rights Agreement, the DTC Agreement, the Securities, the Exchange Securities, the Escrow Agreement and
the Indenture are referred to herein as the “Transaction Documents.” 
 The Issuers understand that the Initial
Purchasers propose to make an offering of the Securities on the terms and in the manner set forth herein and in the Pricing Disclosure Package (as defined below) and agree that the Initial Purchasers may resell, subject to the conditions set forth

“Time of Sale”). The Securities are to be offered and sold to or through the Initial Purchasers without being registered with the Securities and Exchange Commission (the “Commission”) under the Securities Act of
1933 (as amended, the “Securities Act,” which term, as used herein, includes the rules and regulations of the Commission promulgated thereunder), in reliance upon exemptions therefrom. Pursuant to the terms of the Securities and the
Indenture, investors who acquire Securities shall be deemed to have agreed that Securities may only be resold or otherwise transferred, after the date hereof, if such Securities are registered for sale under the Securities Act or if an exemption
from the registration requirements of the Securities Act is available (including the exemptions afforded by Rule 144A under the Securities Act (“Rule 144A”) or Regulation S under the Securities Act (“Regulation

may be required by the Securities Act, the Exchange Act or the securities laws of the several states of the United States and any foreign jurisdictions with respect to the Issuers’ obligations under the Registration Rights Agreement. As used
herein, a “Debt Repayment Triggering Event” means any event or condition which gives, or with the giving of notice or lapse of time would give, the holder of any note, debenture or other evidence of indebtedness (or any person
acting on such holder’s behalf) the right to require the repurchase, redemption or repayment of all or a portion of such indebtedness by either of the Issuers or any of their respective Subsidiaries. 

  
 11 

  
 (r)
No Material Actions or Proceedings. Except as described in the Offering Memorandum, there are no actions, suits, claims, investigations or proceedings pending or, to the Issuers’ knowledge, threatened or contemplated to which the Issuers
or any of the Guarantors or any of their respective directors or officers is or would be a party or of which any of their respective properties is or would be subject at law or in equity, before or by any federal, state, local or foreign
governmental or regulatory commission, board, body, authority or agency, or before or by any self-regulatory organization or other non-governmental regulatory authority (including, without limitation, the New York Stock Exchange (the
“NYSE”)), except any such action, suit, claim, investigation or proceeding which, if resolved adversely to either of the Issuers or any of the Guarantors, would not, individually or in the aggregate, have a Material Adverse Effect.
No material labor dispute with the employees of the Issuers or any of their Subsidiaries exists or, to the best of the Issuers’ knowledge, is threatened or imminent. 

(s) Intellectual Property Rights. Each of the Issuers and the Guarantors owns or possesses all inventions, patent
applications, patents, trademarks (both registered and unregistered), trade names, service names, copyrights, trade secrets and other proprietary information described in the Offering Memorandum or any Issuer Additional Written Communication (or any
amendment or supplement thereto), as being owned or licensed by it or which is necessary for the conduct of, or material to, its businesses (collectively, the “Intellectual Property”), except as would not, individually or in the
aggregate, have a Material Adverse Effect, and the Issuers are unaware of any claim to the contrary or any challenge by any other person to the rights of the Partnership, Finance Corp. or any of the Guarantors with respect to the Intellectual
Property. None of the Issuers or the Guarantors has infringed or is infringing the intellectual property of a third party, and none of the Issuers or any of the Guarantors has received notice of a claim by a third party to the contrary. 

(t) All Necessary Permits, etc. Each of the Issuers and each of the Guarantors possess such valid and current
certificates, authorizations or permits issued by the appropriate state, federal or foreign regulatory agencies or bodies necessary to own, lease and operate its properties and to conduct their respective businesses, and neither the Issuers nor any
of Guarantors has received any notice of proceedings relating to the revocation or modification of, or non-compliance with, any such certificate, authorization or permit which, singly or in the aggregate, if the subject of an unfavorable decision,
ruling or finding, would have a Material Adverse Effect. 
 (u) Title to Properties. Each of the Issuers
and each of the Subsidiaries has good and marketable title to all the properties (real and personal) described in the Offering Memorandum or any Issuer Additional Written Communication (or any amendment or supplement thereto) as being owned by any

credit facilities filed as exhibits to the Partnership SEC Documents); all the property described in the Offering Memorandum or any Issuer Additional Written Communication (or any amendment or supplement thereto) as being held under lease by any of
the Issuers or any of the Subsidiaries is held thereby under valid, subsisting and enforceable leases, except as would not, individually or in the aggregate, have a Material Adverse Effect.

 (v)
Tax Law Compliance. 
 (i) The Partnership met for the taxable year ended December 31, 2009, and the
Partnership expects to meet for the taxable year ending December 31, 2010, the gross income requirements of Section 7704(c)(2) of the Internal Revenue Code of 1986, as amended from time to time (the “Code,” which term, as
used herein, includes the regulations and published interpretations thereunder), and accordingly the Partnership is not, and does not reasonably expect to be taxed as a corporation for U.S. federal income tax purposes or for applicable tax purposes.

 (ii) All tax returns required to be filed by the Issuers or any of the Guarantors have been timely filed,
except for such failure to file which would not, individually or in the aggregate, have a Material Adverse Effect, and all taxes and other assessments of a similar nature (whether imposed directly or through withholding) including any interest,
additions to tax or penalties applicable thereto due or claimed to be due from such entities have been timely paid, other than those being contested in good faith and for which adequate reserves have been provided or where such failure to pay would
not, individually or in the aggregate, have a Material Adverse Effect. 
 (w) Issuers and Guarantors Not an
“Investment Company”. Neither of the Issuers nor any Guarantor is, or after receipt of payment for the Securities or after giving effect to the Cameron Acquisition will be, an “investment company” within the meaning of the
Investment Company Act of 1940, as amended (the “Investment Company Act,” which term, as used herein, includes the rules and regulations of the Commission promulgated thereunder). 

(x) Insurance. Each of the Issuers and each of the Guarantors are insured with policies in such amounts and
with such deductibles and covering such risks as the Partnership believes in its sole discretion to be prudent for its businesses taken as a whole. The Issuers have no reason to believe that they or any of the Guarantors will not be able (i) to
renew their existing insurance coverage as and when such policies expire or (ii) to obtain comparable coverage from similar institutions as may be necessary or appropriate to conduct their respective businesses as now conducted, except where
such non-renewal or inability to obtain comparable coverage would not, individually or in the aggregate, have a Material Adverse Effect. 
 (y) No Price Stabilization or Manipulation. None of the Issuers or the Guarantors or any of their respective directors, officers, Affiliates or controlling persons has taken or will take, directly
or indirectly, any action designed to or that might reasonably be expected to cause or result in stabilization or manipulation of the price of any security of either of the Issuers to facilitate the sale or resale of the Securities. 

  
 13 

  
 (z)
Solvency. The Partnership and each of the Guarantors (other than those Guarantors specified on Schedule B) is, and immediately after the Closing Date will be, Solvent. As used herein, the term “Solvent” means, with respect to
any person on a particular date, that on such date (i) the fair market value of the assets of such person is greater than the total amount of liabilities (including contingent liabilities) of such person, (ii) the present fair salable
value of the assets of such person is greater than the amount that will be required to pay the probable liabilities of such person on its debts as they become absolute and matured, (iii) such person is able to realize upon its assets and pay
its debts and other liabilities, including contingent obligations, as they mature and (iv) such person does not have unreasonably small capital. 
 (aa) Company’s Accounting System. Except as disclosed in the Partnership SEC Documents, the Partnership, Finance Corp. and the Guarantors maintain a system of internal accounting controls that
is in compliance with the Sarbanes-Oxley Act of 2002 (the “Sarbanes Oxley Act,” which term, as used herein, includes the rules and regulations of the Commission promulgated thereunder) and is sufficient to provide reasonable
assurances that: (i) transactions are executed in accordance with management’s general or specific authorization; (ii) transactions are recorded as necessary to permit preparation of financial statements in conformity with GAAP and to
maintain accountability for assets; (iii) access to assets is permitted only in accordance with management’s general or specific authorization; and (iv) the recorded accountability for assets is compared with existing assets at
reasonable intervals and appropriate action is taken with respect to any differences. 
 (bb) Disclosure
Controls and Procedures. The Partnership has established and maintains and evaluates disclosure controls and procedures (as such term is defined in Rules 13a-15 and 15d-15 under the Exchange Act); such disclosure controls and procedures are
designed to ensure that material information relating to the Partnership, including its consolidated subsidiaries, is made known to the General Partner’s Chief Executive Officer and Chief Financial Officer by others within those entities, and
such disclosure controls and procedures are effective to perform the functions for which they were established; the Partnership’s independent auditors and the Audit Committee of the Board of Directors of the General Partner have been advised
of: (i) all significant deficiencies, if any, in the design or operation of internal controls which could adversely affect the Partnership’s ability to record, process, summarize and report financial data; and (ii) all fraud, if any,
whether or not material, that involves management or other employees who have a role in the Partnership’s internal controls; all material weaknesses, if any, in internal controls have been identified to the Partnership’s independent
auditors; since the date of the most recent evaluation of such disclosure controls and procedures and internal controls, there have been no significant changes in internal controls or in other factors that could significantly affect internal
controls, including any corrective actions with regard to significant deficiencies and material weaknesses; the principal executive officers (or their equivalents) and principal financial officers (or their equivalents) of the Partnership have made
all certifications required by the Sarbanes-Oxley Act, and the statements contained in each such certification are complete and correct; the Partnership, its Subsidiaries and the Partnership’s directors and officers are each in compliance in
all material respects with all applicable effective provisions of the Sarbanes-Oxley Act and the rules and regulations of the NYSE promulgated thereunder. 

  
 14 

  
 (cc)
Regulations T, U, X. Neither Issuer nor any Guarantor nor any agent thereof acting on their behalf has taken, and none of them will take, any action that might cause this Agreement or the issuance or sale of the Securities to violate
Regulation T, Regulation U or Regulation X of the Board of Governors of the Federal Reserve System. 
 (dd)
Compliance with and Liability Under Environmental Laws. The Issuers and the Guarantors and their respective properties, assets and operations are in compliance with, and each of the Issuers and the Guarantors hold all permits, authorizations
and approvals required under, Environmental Laws (as defined below), except to the extent that failure to so comply or to hold such permits, authorizations or approvals would not, individually or in the aggregate, have a Material Adverse Effect;
there are no past, present or, to the Issuers’ knowledge, reasonably anticipated future events, conditions, circumstances, activities, practices, actions, omissions or plans that could reasonably be expected to give rise to any material costs
or liabilities to any of the Issuers or the Guarantors under, or to interfere with or prevent compliance by any of the Issuers or the Guarantors with, Environmental Laws; except as would not, individually or in the aggregate, have a Material Adverse
Effect, none of the Partnership, Finance Corp. or any of the Guarantors (i) is the subject of any investigation, (ii) has received any notice or claim, (iii) is a party to or affected by any pending or, to the Issuers’ knowledge,
threatened action, suit or proceeding, (iv) is bound by any judgment, decree or order or (v) has entered into any agreement, in each case relating to any alleged violation of any Environmental Law or any actual or alleged release or
threatened release or cleanup at any location of any Hazardous Materials (as defined below) except as described in the Offering Memorandum or that would not, individually or in the aggregate, have a Material Adverse Effect (as used herein,
“Environmental Law” means any federal, state, local or foreign law, statute, ordinance, rule, regulation, order, decree, judgment, injunction, permit, license, authorization or other binding requirement, or common law, relating to
health, safety or the protection, cleanup or restoration of the environment or natural resources, including those relating to the distribution, processing, generation, treatment, storage, disposal, transportation, other handling or release or
threatened release of Hazardous Materials, and “Hazardous Materials” means any material (including, without limitation, pollutants, contaminants, hazardous or toxic substances or wastes) that is regulated by or may give rise to
liability under any Environmental Law). 
 (ee) ERISA Compliance. The Issuers and the Guarantors and any
“employee benefit plan” (as defined under the Employee Retirement Income Security Act of 1974 (as amended, “ERISA,” which term, as used herein, includes the regulations and published interpretations thereunder) established
or maintained by the Issuers, the Guarantors or their ERISA Affiliates (as defined below) are in compliance in all material respects with ERISA and, to the knowledge of the Issuers, each “multiemployer plan” (as defined in
Section 4001 of ERISA) to which the Issuers, the Guarantors or an ERISA Affiliate contributes (a “Multiemployer Plan”) is in compliance in all material respects with ERISA, except in each case as such noncompliance as would not
have a Material Adverse Effect. “ERISA Affiliate” means, with respect to either of the Issuers or any of the Guarantors, any member of any group of organizations described in Section 414(b), (c), (m) or (o) of the
Code of which either of the Issuers or such Guarantor is a member. No “reportable event” (as defined under ERISA) has occurred within the last six years or is reasonably expected to occur with respect to any “employee benefit
plan” established or maintained by either of the Issuers, any of the Guarantors or any of their ERISA Affiliates. No “single employer plan” (as defined in Section 4001 of ERISA) established or maintained by either of the Issuers,
any of the Guarantors or any of their ERISA Affiliates, if such “employee benefit plan” were terminated as of the last day of the most recent plan year ended prior to the date hereof, would have any “amount of unfunded benefit
liabilities” (as defined in Section 401(a)(18) of ERISA). None of the Issuers, any of the Guarantors or any of their ERISA Affiliates has within the last six years incurred or reasonably expects to incur any unpaid liability under
(i) Title IV of ERISA with respect to termination of, or withdrawal from, any “employee benefit plan” or (ii) Sections 412, 4971, 4975 or 4980B of the Code, except as such liability as would not have a Material Adverse Effect.
Each “employee benefit plan” established or maintained by either of the Issuers, any of the Guarantors or any of their ERISA Affiliates that is intended to be qualified under Section 401 of the Code is so qualified and, to the
knowledge of the Issuers, nothing has occurred, whether by action or failure to act, which would reasonably be expected to cause the loss of such qualification. 

  
 15 

  
 (ff)
Compliance with Labor Laws. None of the Issuers or the Guarantors is engaged in any unfair labor practice; except for matters which would not, individually or in the aggregate, have a Material Adverse Effect, (i) there is (A) no
unfair labor practice complaint pending or, to the Issuers’ knowledge, threatened against the Issuers or any of the Guarantors before the National Labor Relations Board, and no grievance or arbitration proceeding arising out of or under
collective bargaining agreements is pending or, to the Issuers’ knowledge, threatened, (B) no strike, labor dispute, slowdown or stoppage pending or, to the Issuers’ knowledge, threatened against the Issuers or any of the Guarantors
and (C) no union representation dispute currently existing concerning the employees of the Issuers or any of the Gurantors, (ii) to the Issuers’ knowledge, no union organizing activities are currently taking place concerning the
employees of the Issuers or any of the Guarantors and (iii) there has been no violation of any federal, state, local or foreign law relating to discrimination in the hiring, promotion or pay of employees, any applicable wage or hour laws or any
provision of ERISA concerning the employees of the Issuers or any of the Guarantors. 
 (gg) No Unlawful
Contributions or Other Payments. Neither of the Issuers nor any of their Subsidiaries nor any director, officer, agent, employee or other person acting on behalf of the Issuers or any of their Subsidiaries has, in the course of its actions for,
or on behalf of, either of the Issuers or any of their Subsidiaries (i) used any corporate funds for any unlawful contribution, gift, entertainment or other unlawful expenses relating to political activity, (ii) made any direct or indirect
unlawful payment to any foreign or domestic government official or employee from corporate funds, (iii) violated or is in violation of any provision of the U.S. Foreign Corrupt Practices Act of 1977, as amended, and the rules and regulations
thereunder or (iv) made any unlawful bribe, rebate, payoff, influence payment, kickback or other unlawful payment to any foreign or domestic government official or employee. 

  
 16 

  
 (hh)
No Conflict with Money Laundering Laws. The operations of the Issuers and their Subsidiaries are and have been conducted at all times in compliance with applicable financial recordkeeping and reporting requirements of the Currency and Foreign
Transactions Reporting Act of 1970, as amended, the money laundering statutes of all applicable jurisdictions, the rules and regulations thereunder and any related or similar rules, regulations or guidelines issued, administered or enforced by any
governmental agency (collectively, the “Money Laundering Laws”) and no action, suit or proceeding by or before any court or governmental agency, authority or body or any arbitrator involving the Issuers or their Subsidiaries with
respect to the Money Laundering Laws is pending or, to the best knowledge of the Issuers, threatened. 
 (ii)
No Conflict with OFAC Laws. Neither of the Issuers nor any of their Subsidiaries (or Cameron Highway Oil Pipeline Company) nor, to the knowledge of the Issuers, any director, officer, agent, employee, Affiliate or person acting on behalf of
the Issuers or their Subsidiaries (or Cameron Highway Oil Pipeline Company) is currently subject to any U.S. sanctions administered by the Office of Foreign Assets Control of the U.S. Treasury Department (“OFAC”). 

(jj) Regulation S. The Issuers, the Guarantors and their respective Affiliates and all persons acting on their
behalf (other than the Initial Purchasers, as to whom the Issuers and the Guarantors make no representation) have complied with and will comply with the offering restriction requirements of Regulation S in connection with the offering of the
Securities outside the United States and, in connection therewith, the Offering Memorandum will contain the disclosure required by Rule 902. The Securities sold in reliance on Regulation S will be represented upon issuance by a temporary global
security that may not be exchanged for definitive securities until the expiration of the 40-day restricted period referred to in Rule 903 of the Securities Act and only upon certification of beneficial ownership of such Securities by non-U.S.
persons or U.S. persons who purchased such Securities in transactions that were exempt from the registration requirements of the Securities Act. 
 (kk) Certain Statements. The statements set forth in the Offering Memorandum under the captions “Certain United States Federal Income Tax Considerations,” and “Summary – Recent
Events – Cameron Highway Acquisition” (together with the Partnership’s Current Report on Form 8-K filed October 28, 2010), insofar as they purport to describe the provisions of the laws and documents referred to therein, are
accurate, complete and fair. 
 (ll) No Adverse Events or Material Changes in Operation of Business. 

 (i) Neither of the Issuers nor any of the Guarantors has sustained since the date of the latest audited
financial statements included in the Offering Memorandum any material loss or interference with its business from fire, explosion, flood or other calamity, whether or not covered by insurance, or from any labor dispute or court or governmental

long-term debt of the Partnership, Finance Corp. or any of the Guarantors or any material adverse change, or any development involving a prospective material adverse change, in or affecting the general affairs, management, financial position,
stockholders’ equity or results of operations of the Partnership, Finance Corp. and the Guarantors, otherwise than as set forth or contemplated in the Offering Memorandum. 

  
 17

SECTION 2. Purchase, Sale and Delivery of the Securities. 

(a) The Securities. Each of the Issuers and each of the Guarantors agrees to issue and sell to the Initial Purchasers, severally

Offering Memorandum as modified only by the information contained in the Pricing Supplement unless otherwise consented to by the Representative. The Issuers will not amend or supplement the Preliminary Offering Memorandum or the Pricing Supplement
unless the Representative shall previously have been furnished a copy of the proposed amendment or supplement and shall not have reasonably objected in writing to such amendment or supplement (unless the Issuers are advised by counsel that they are
required by law to so amend or supplement the Preliminary Offering Memorandum or Pricing Supplement). The Partnership will not amend or supplement the Final Offering Memorandum prior to the Closing Date unless the Representative shall previously

 (b)
Amendments and Supplements to the Final Offering Memorandum and Other Securities Act Matters. If at any time prior to the Closing Date (i) any event shall occur or condition shall exist as a result of which any of the Pricing Disclosure
Package as then amended or supplemented would include any untrue statement of a material fact or omit to state any material fact necessary in order to make the statements therein, in the light of the circumstances under which they were made, not
misleading or (ii) it is necessary to amend or supplement any of the Pricing Disclosure Package to comply with law, the Issuers and the Guarantors will immediately notify the Initial Purchasers thereof and forthwith prepare and (subject to
Section 3(a) hereof) furnish to the Initial Purchasers such amendments or supplements to any of the Pricing Disclosure Package as may be necessary so that the statements in any of the Pricing Disclosure Package as so amended or supplemented
will not, in the light of the circumstances under which they were made, be misleading or so that any of the Pricing Disclosure Package will comply with all applicable law. If, prior to the completion of the placement of the Securities by the Initial
Purchasers with the Subsequent Purchasers, any event shall occur or condition exist as a result of which it is necessary to amend or supplement the Final Offering Memorandum, as then amended or supplemented, in order to make the statements therein,
in the light of the circumstances when the Final Offering Memorandum is delivered to a Subsequent Purchaser, not misleading, or if in the judgment of the Representative or counsel for the Initial Purchasers it is otherwise necessary to amend or
supplement the Final Offering Memorandum to comply with law, the Issuers and the Guarantors agree to promptly prepare (subject to Section 3 hereof), file with the Commission (with respect to Incorporated Documents) and furnish at its own
expense to the Initial Purchasers, amendments or supplements to the Final Offering Memorandum so that the statements in the Final Offering Memorandum as so amended or supplemented will not, in the light of the circumstances at the Closing Date and

and shall continue such qualifications, registrations and exemptions in effect so long as required for the distribution of the Securities. None of the Issuers or any of the Guarantors shall be required to qualify as a foreign entity or to take any
action that would subject it to general service of process in any such jurisdiction where it is not presently qualified or where it would be subject to taxation as a foreign entity. The Issuers will advise the Representative promptly of the
suspension of the qualification or registration of (or any such exemption relating to) the Securities for offering, sale or trading in any jurisdiction or any initiation or threat of any proceeding for any such purpose, and in the event of the
issuance of any order suspending such qualification, registration or exemption, each of the Issuers and the Guarantors shall use their respective reasonable best efforts to obtain the withdrawal thereof at the earliest possible moment.

basis, with the Commission and the NYSE all reports and documents required to be filed under Section 13 or 15 of the Exchange Act. Additionally, at any time when the Partnership is not subject to Section 13 or 15 of the Exchange Act and
the Securities are “restricted securities” within the meaning of Rule 144(a)(3) under the Securities Act, for the benefit of holders and beneficial owners from time to time of the Securities, the Issuers shall furnish, at its expense, upon
request, to holders and beneficial owners of Securities and prospective purchasers of Securities information (“Additional Issuer Information”) satisfying the requirements of Rule 144A(d) under the Securities Act. 

(h) Agreement Not To Offer or Sell Additional Securities. During the period of 90 days following the date hereof,
the Issuers will not, without the prior written consent of Merrill Lynch (which consent may be withheld at the sole discretion of Merrill Lynch), directly or indirectly, sell, offer, contract or grant any option to sell, pledge, transfer or
establish an open “put equivalent position” within the meaning of Rule 16a-1 under the Exchange Act, or otherwise dispose of or transfer, or announce the offering of, or file any registration statement under the Securities Act in respect
of, any debt securities of the Partnership or securities exchangeable for or convertible into debt securities of the Partnership (other than as contemplated by this Agreement and to register the Exchange Securities). 

(i) No Integration. The Issuers agree that they will not and will cause their Affiliates not to make any offer or
sale of securities of the Issuers of any class if, as a result of the doctrine of “integration” referred to in Rule 502 under the Securities Act, such offer or sale would render invalid (for the purpose of (i) the sale of the
Securities by the Partnership to the Initial Purchasers, (ii) the resale of the Securities by the Initial Purchasers to Subsequent Purchasers or (iii) the resale of the Securities by such Subsequent Purchasers to others) the exemption from
the registration requirements of the Securities Act provided by Section 4(2) thereof or by Rule 144A or by Regulation S thereunder or otherwise.

covenant is given) to (i) solicit offers for, or offer or sell, the Securities by means of any form of general solicitation or general advertising within the meaning of Rule 502(c) of Regulation D or in any manner involving a public offering
within the meaning of Section 4(2) of the Securities Act or (ii) engage in any directed selling efforts with respect to the Securities within the meaning of Regulation S, and the Issuers will and will cause all such persons to comply with
the offering restrictions requirement of Regulation S with respect to the Securities. 
 (k) No Restricted
Resales. During the period of one year after the Closing Date, the Issuers will not, and will not permit any of their affiliates (as defined in Rule 144 under the Securities Act) to resell any of the Securities that constitute “restricted
securities” under Rule 144 under the Securities Act that have been reacquired by any of them other than pursuant to an effective registration statement under the Securities Act or in accordance with Rule 144 under the Securities Act.

Disclosure Package and the Final Offering Memorandum; and 

  
 23 

  
 (ii)
there shall not have occurred any downgrading, nor shall any notice have been given of any intended or potential downgrading or of any review for a possible change that does not indicate the direction of the possible change, in the rating accorded
the Partnership, Finance Corp. or any of the Guarantors or any of their respective securities by any “nationally recognized statistical rating organization” as such term is defined for purposes of Rule 436 under the Securities Act.

 (c) Opinion of Counsel for the Issuers. On the Closing Date the Initial Purchasers shall have received
the favorable opinions of each of Akin Gump Strauss Hauer & Feld LLP, counsel for the Issuers, Liskow & Lewis, counsel for the Partnership, and the General Counsel of the Partnership addressed to the Initial Purchasers, and dated

(i) for the period from and after the date of this Agreement and prior to the Closing Date there has not occurred any
Material Adverse Effect; 
 (ii) the representations, warranties and covenants of the Issuers and the Guarantors

(iii) the Issuers and Guarantors have complied in all material respects with all the agreements and satisfied all the
conditions on its part to be performed or satisfied at or prior to the Closing Date. 

  
 24

 (h) Additional Documents. On or before the Closing Date, the Initial Purchasers and counsel for the Initial Purchasers shall have received such information, documents and opinions as they may
reasonably require for the purposes of enabling them to pass upon the issuance and sale of the Securities as contemplated herein, or in order to evidence the accuracy of any of the representations and warranties, or the satisfaction of any of the
conditions or agreements, herein contained. 
 If any condition specified in this Section 5 is not satisfied when and as
required to be satisfied, this Agreement may be terminated by the Representative by notice to the Partnership at any time on or prior to the Closing Date, which termination shall be without liability on the part of any party to any other party,
except that Sections 4, 6, 8 and 9 hereof shall at all times be effective and shall survive such termination. 
 SECTION 6.
Reimbursement of Initial Purchasers’ Expenses. If this Agreement is terminated by the Representative pursuant to Section 5 or 10 hereof, including if the sale to the Initial Purchasers of the Securities on the Closing Date is not
consummated because of any refusal, inability or failure on the part of the Issuers to perform any agreement herein or to comply with any provision hereof, each of the Issuers agrees to reimburse the Initial Purchasers, severally, upon demand for
all out-of-pocket expenses that shall have been reasonably incurred by the Initial Purchasers in connection with the proposed purchase and the offering and sale of the Securities, including, without limitation, fees and disbursements of counsel,
printing expenses, travel expenses, postage, facsimile and telephone charges. 
 SECTION 7. Offer, Sale and Resale
Procedures. Each of the Initial Purchasers, on the one hand, and the each of the Issuers and the Guarantors, on the other hand, hereby agree to observe the following procedures in connection with the offer and sale of the Securities:

 (a) Offers and sales of the Securities will be made only by the Initial Purchasers or Affiliates thereof
qualified to do so in the jurisdictions in which such offers or sales are made. Each such offer or sale shall only be made to persons whom the offeror or seller reasonably believes to be Qualified Institutional Buyers or non-U.S. persons outside the
United States to whom the offeror or seller reasonably believes offers and sales of the Securities may be made in reliance upon Regulation S upon the terms and conditions set forth in Annex I hereto, which Annex I is hereby expressly made a part
hereof. 

  
 25 

  
 (b) The
Securities will be offered by approaching prospective Subsequent Purchasers on an individual basis. No general solicitation or general advertising (within the meaning of Rule 502 under the Securities Act) will be used in the United States in
connection with the offering of the Securities. 
 (c) Upon original issuance by the Issuers, and until such time
as the same is no longer required under the applicable requirements of the Securities Act, the Securities (and all securities issued in exchange therefor or in substitution thereof, other than the Exchange Securities) shall bear the following
legend: 
 “THE NOTES EVIDENCED HEREBY HAVE NOT BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933, AS AMENDED (THE
“SECURITIES ACT”), OR ANY STATE SECURITIES LAWS. NEITHER SUCH NOTES NOR ANY INTEREST OR PARTICIPATION HEREIN MAY BE OFFERED, SOLD, ASSIGNED, TRANSFERRED, PLEDGED, ENCUMBERED OR OTHERWISE DISPOSED OF IN THE ABSENCE OF SUCH REGISTRATION OR
UNLESS SUCH TRANSACTION IS EXEMPT FROM, OR NOT SUBJECT TO, THE REGISTRATION REQUIREMENTS OF THE SECURITIES ACT. THE HOLDER OF ANY NOTE EVIDENCED HEREBY BY ITS ACCEPTANCE HEREOF (1) REPRESENTS THAT (A) IT IS A “QUALIFIED INSTITUTIONAL
BUYER” (AS DEFINED IN RULE 144A UNDER THE SECURITIES ACT) OR (B) IT IS NOT A U.S. PERSON AND IS ACQUIRING SUCH NOTE IN AN “OFFSHORE TRANSACTION” PURSUANT TO RULE 904 OF REGULATION S UNDER THE SECURITIES ACT, (2) AGREES THAT
IT WILL NOT, PRIOR TO THE DATE WHICH IS ONE YEAR AFTER THE LATER OF THE ORIGINAL ISSUE DATE HEREOF (OR OF ANY PREDECESSOR OF SUCH NOTE) OR THE LAST DAY ON WHICH THE COMPANY OR ANY AFFILIATE OF THE COMPANY WERE THE OWNERS OF SUCH NOTE (OR ANY
PREDECESSOR OF SUCH NOTE) (THE “RESALE RESTRICTION TERMINATION DATE”), OFFER, SELL OR OTHERWISE TRANSFER SUCH NOTE EXCEPT (A) TO AN ISSUER OR ANY SUBSIDIARY THEREOF, (B) PURSUANT TO AN EFFECTIVE REGISTRATION STATEMENT UNDER THE
SECURITIES ACT, (C) FOR SO LONG AS THE NOTES ARE ELIGIBLE FOR RESALE PURSUANT TO RULE 144A UNDER THE SECURITIES ACT (“RULE 144A”), TO A PERSON IT REASONABLY BELIEVES IS A “QUALIFIED INSTITUTIONAL BUYER” AS DEFINED IN RULE
144A THAT PURCHASES FOR ITS OWN ACCOUNT OR FOR THE ACCOUNT OF A QUALIFIED INSTITUTIONAL BUYER TO WHOM NOTICE IS GIVEN THAT THE TRANSFER IS BEING MADE IN RELIANCE ON RULE 144A, (D) PURSUANT TO OFFERS AND SALES TO NON-U.S. PERSONS THAT OCCUR
OUTSIDE THE UNITED STATES WITHIN THE MEANING OF REGULATION S UNDER THE SECURITIES ACT, (E) PURSUANT TO RULE 144 UNDER THE SECURITIES ACT OR (F) PURSUANT TO ANOTHER AVAILABLE EXEMPTION FROM THE REGISTRATION REQUIREMENTS OF THE SECURITIES
ACT AND (3) AGREES THAT IT WILL GIVE TO EACH PERSON TO WHOM SUCH NOTE IS TRANSFERRED PRIOR TO THE RESALE RESTRICTION TERMINATION DATE A NOTICE SUBSTANTIALLY TO THE EFFECT OF THIS LEGEND, SUBJECT TO THE ISSUERS’ AND THE TRUSTEE’S RIGHT
PRIOR TO ANY SUCH OFFER, SALE OR TRANSFER (i) THAT IS (A) PURSUANT TO CLAUSE (2)(D) PRIOR TO THE END OF THE 40 DAY DISTRIBUTION COMPLIANCE PERIOD WITHIN THE MEANING OF REGULATION S UNDER THE SECURITIES ACT OR (B) PURSUANT TO
CLAUSE (2)(F) PRIOR TO THE RESALE RESTRICTION TERMINATION DATE TO REQUIRE THE DELIVERY OF AN OPINION OF COUNSEL, CERTIFICATION AND/OR OTHER INFORMATION SATISFACTORY TO EACH OF THEM, AND (ii) IN EACH OF THE FOREGOING CASES IN CLAUSES (i)(A)
OR (B), TO REQUIRE THAT A CERTIFICATE OF TRANSFER IN THE FORM APPEARING ON THIS NOTE IS COMPLETED AND DELIVERED BY THE TRANSFEROR TO THE TRUSTEE. THIS LEGEND WILL BE REMOVED AS TO ANY NOTE EVIDENCED HEREBY UPON DELIVERY TO THE TRUSTEE BY THE COMPANY
OR THE HOLDER THEREOF OF A WRITTEN REQUEST FOR THE REMOVAL HEREOF, IN ANY CASE AT ANY TIME AFTER THE RESALE RESTRICTION TERMINATION DATE. AS USED HEREIN, THE TERMS “OFFSHORE TRANSACTION,” “UNITED STATES” AND “U.S.
PERSON” HAVE THE MEANINGS GIVEN TO THEM BY REGULATION S UNDER THE SECURITIES ACT.” 

  
 26 

  
 Following the sale of
the Securities by the Initial Purchasers to Subsequent Purchasers pursuant to the terms hereof, the Initial Purchasers shall not be liable or responsible to the Issuers or the Guarantors for any losses, damages or liabilities suffered or incurred by
any of the Issuers or the Guarantors, including any losses, damages or liabilities under the Securities Act, arising from or relating to any resale or transfer of any Security. 

SECTION 8. Indemnification. 
 (a) Indemnification of the Initial Purchasers. Each of the Issuers and the Guarantors, jointly and severally, agrees to indemnify and hold harmless each Initial Purchaser, its affiliates,
directors, officers and employees, and each person, if any, who controls any Initial Purchaser within the meaning of the Securities Act and the Exchange Act against any loss, claim, damage, liability or expense, as incurred, to which such Initial
Purchaser, affiliate, director, officer, employee or controlling person may become subject under the Securities Act, the Exchange Act or other federal or state statutory law or regulation, or at common law or otherwise (including in settlement of
any litigation, if such settlement is effected with the written consent of the Partnership), insofar as such loss, claim, damage, liability or expense (or actions in respect thereof as contemplated below) arises out of or is based upon any
untrue statement or alleged untrue statement of a material fact contained in the Preliminary Offering Memorandum, the Pricing Supplement, any Issuer Additional Written Communication or the Final Offering Memorandum (or any amendment or supplement
thereto), or the omission or alleged omission therefrom of a material fact necessary in order to make the statements therein, in the light of the circumstances under which they were made, not misleading; and to reimburse each Initial Purchaser and
each such affiliate, director, officer, employee or controlling person for any and all expenses (including the reasonable fees and disbursements of counsel chosen by Merrill Lynch) as such expenses are reasonably incurred by such Initial Purchaser
or such affiliate, director, officer, employee or controlling person in connection with investigating, defending, settling, compromising or paying any such loss, claim, damage, liability, expense or action; provided, however, that the foregoing
indemnity agreement shall not apply to any loss, claim, damage, liability or expense to the extent, but only to the extent, arising out of or based upon any untrue statement or alleged untrue statement or omission or alleged omission made in
reliance upon and in conformity with written information furnished to the Partnership by such Initial Purchaser through the Representative expressly for use in the Preliminary Offering Memorandum, the Pricing Supplement, any Issuer Additional
Written Communication or the Final Offering Memorandum (or any amendment or supplement thereto). The indemnity agreement set forth in this Section 8(a) shall be in addition to any liabilities that the Issuers or Guarantors may otherwise have.

  
 27 

  
 (b) Indemnification
of the Issuers and the Guarantors. Each Initial Purchaser agrees, severally and not jointly, to indemnify and hold harmless each of the Issuers and Guarantors, each of their respective directors and each person, if any, who controls the each of
the Issuers or any Guarantor within the meaning of the Securities Act or the Exchange Act, against any loss, claim, damage, liability or expense, as incurred, to which each Issuer, any Guarantor or any such director or controlling person may become
subject, under the Securities Act, the Exchange Act, or other federal or state statutory law or regulation, or at common law or otherwise (including in settlement of any litigation, if such settlement is effected with the written consent of such
Initial Purchaser), insofar as such loss, claim, damage, liability or expense (or actions in respect thereof as contemplated below) arises out of or is based upon (i) any untrue statement or alleged untrue statement of a material fact contained
in the Preliminary Offering Memorandum, the Pricing Supplement, any Issuer Additional Written Communication or the Final Offering Memorandum (or any amendment or supplement thereto), or (ii) the omission or alleged omission therefrom of a
material fact necessary in order to make the statements therein, in the light of the circumstances under which they were made, not misleading, in each case to the extent, but only to the extent, that such untrue statement or alleged untrue statement
or omission or alleged omission was made in the Preliminary Offering Memorandum, the Pricing Supplement, any Issuer Additional Written Communication or the Final Offering Memorandum (or any amendment or supplement thereto), in reliance upon and in
conformity with written information furnished to the Issuers by such Initial Purchaser through the Representative expressly for use therein; and to reimburse each Issuer, any Guarantor and each such director or controlling person for any and all
expenses (including the fees and disbursements of counsel) as such expenses are reasonably incurred by each Issuer, any Guarantor or such director or controlling person in connection with investigating, defending, settling, compromising or paying
any such loss, claim, damage, liability, expense or action. Each of the Issuers and the Guarantors hereby acknowledge that the only information that the Initial Purchasers through the Representative have furnished to the Partnership expressly for
use in the Preliminary Offering Memorandum, the Pricing Supplement, any Issuer Additional Written Communication or the Final Offering Memorandum (or any amendment or supplement thereto) are the statements set forth in the table in the first
paragraph, the first sentence of the fifth paragraph, the third and fourth sentences of the seventh paragraph, the first and second sentences of the tenth paragraph and the first sentence of the twelfth paragraph under the caption “Plan of
Distribution” in the Preliminary Offering Memorandum and the Final Offering Memorandum. The indemnity agreement set forth in this Section 8(b) shall be in addition to any liabilities that each Initial Purchaser may otherwise have.

  
 28 

  
 (c) Notifications
and Other Indemnification Procedures. Promptly after receipt by an indemnified party under this Section 8 of notice of the commencement of any action, such indemnified party will, if a claim in respect thereof is to be made against
an indemnifying party under this Section 8, notify the indemnifying party in writing of the commencement thereof; provided that the failure to so notify the indemnifying party will not relieve it from any liability that it may have to any
indemnified party under this Section 8 except to the extent that it has been materially prejudiced by such failure (through the forfeiture of substantive rights and defenses) and shall not relieve the indemnifying party from any liability that
the indemnifying party may have to an indemnified party other than under this Section 8. In case any such action is brought against any indemnified party and such indemnified party seeks or intends to seek indemnity from an indemnifying party,
the indemnifying party will be entitled to participate in and, to the extent that it shall elect, jointly with all other indemnifying parties similarly notified, by written notice delivered to the indemnified party promptly after receiving the
aforesaid notice from such indemnified party, to assume the defense thereof with counsel reasonably satisfactory to such indemnified party; provided, however, if the defendants in any such action include both the indemnified party and the
indemnifying party and the indemnified party shall have reasonably concluded that a conflict may arise between the positions of the indemnifying party and the indemnified party in conducting the defense of any such action or that there may be legal
defenses available to it and/or other indemnified parties that are different from or additional to those available to the indemnifying party, the indemnified party or parties shall have the right to select separate counsel to assume such legal
defenses and to otherwise participate in the defense of such action on behalf of such indemnified party or parties. Upon receipt of notice from the indemnifying party to such indemnified party of such indemnifying party’s election so to assume
the defense of such action and approval by the indemnified party of counsel, the indemnifying party will not be liable to such indemnified party under this Section 8 for any legal or other expenses subsequently incurred by such indemnified
party in connection with the defense thereof unless (i) the indemnified party shall have employed separate counsel in accordance with the proviso to the immediately preceding sentence (it being understood, however, that the indemnifying party
shall not be liable for the expenses of more than one separate counsel (together with local counsel (in each jurisdiction)), which shall be selected by Merrill Lynch (in the case of counsel representing the Initial Purchasers or their related
persons), representing the indemnified parties who are parties to such action) or (ii) the indemnifying party shall not have employed counsel satisfactory to the indemnified party to represent the indemnified party within a reasonable time
after notice of commencement of the action, in each of which cases the fees and expenses of counsel shall be at the expense of the indemnifying party. 
 (d) Settlements. The indemnifying party under this Section 8 shall not be liable for any settlement of any proceeding effected without its written consent, which will not be unreasonably
withheld, but if settled with such consent or if there be a final judgment for the plaintiff, the indemnifying party agrees to indemnify the indemnified party against any loss, claim, damage, liability or expense by reason of such settlement or
judgment. Notwithstanding the foregoing sentence, if at any time an indemnified party shall have requested an indemnifying party to reimburse the indemnified party for fees and expenses of counsel as contemplated by this Section 8, the
indemnifying party agrees that it shall be liable for any settlement of any proceeding effected without its written consent if (i) such settlement is entered into more than 30 days after receipt by such indemnifying party of the aforesaid
request and (ii) such indemnifying party shall not have reimbursed the indemnified party in accordance with such request or disputed in good faith the indemnified party’s entitlement to such reimbursement prior to the date of such
settlement. No indemnifying party shall, without the prior written consent of the indemnified party, effect any settlement, compromise or consent to the entry of judgment in any pending or threatened action, suit or proceeding in respect of which
any indemnified party is or could have been a party and indemnity was or could have been sought hereunder by such indemnified party, unless such settlement, compromise or consent (i) includes an unconditional release of such indemnified party
from all liability on claims that are the subject matter of such action, suit or proceeding and (ii) does not include any statements as to or any findings of fault, culpability or failure to act by or on behalf of any indemnified party.

  
 29 

  
 SECTION 9.
Contribution. If the indemnification provided for in Section 8 hereof is for any reason held to be unavailable to or otherwise insufficient to hold harmless an indemnified party in respect of any losses, claims, damages, liabilities or
expenses referred to therein, then each indemnifying party shall contribute to the aggregate amount paid or payable by such indemnified party, as incurred, as a result of any losses, claims, damages, liabilities or expenses referred to therein
(i) in such proportion as is appropriate to reflect the relative benefits received by the Issuers and the Guarantors, on the one hand, and the Initial Purchasers, on the other hand, from the offering of the Securities pursuant to this Agreement
or (ii) if the allocation provided by clause (i) above is not permitted by applicable law, in such proportion as is appropriate to reflect not only the relative benefits referred to in clause (i) above but also the relative fault of
the Issuers and the Guarantors, on the one hand, and the Initial Purchasers, on the other hand, in connection with the statements or omissions or inaccuracies in the representations and warranties herein that resulted in such losses, claims,
damages, liabilities or expenses, as well as any other relevant equitable considerations. The relative benefits received by the Issuers and the Guarantors, on the one hand, and the Initial Purchasers, on the other hand, in connection with the
offering of the Securities pursuant to this Agreement shall be deemed to be in the same respective proportions as the total net proceeds from the offering of the Securities pursuant to this Agreement (before deducting expenses) received by the
Issuers and the total discount received by the Initial Purchasers bear to the aggregate initial offering price of the Securities. The relative fault of the Issuers and the Guarantors, on the one hand, and the Initial Purchasers, on the other hand,
shall be determined by reference to, among other things, whether any such untrue or alleged untrue statement of a material fact or omission or alleged omission to state a material fact or any such inaccurate or alleged inaccurate representation or
warranty relates to information supplied by the Issuers and the Guarantors, on the one hand, or the Initial Purchasers, on the other hand, and the parties’ relative intent, knowledge, access to information and opportunity to correct or prevent
such statement or omission or inaccuracy. 
 The amount paid or payable by a party as a result of the losses, claims, damages,
liabilities and expenses referred to above shall be deemed to include, subject to the limitations set forth in Section 8 hereof, any legal or other fees or expenses reasonably incurred by such party in connection with investigating or defending
any action or claim. The provisions set forth in Section 8 hereof with respect to notice of commencement of any action shall apply if a claim for contribution is to be made under this Section 9; provided, however, that no additional notice
shall be required with respect to any action for which notice has been given under Section 8 hereof for purposes of indemnification. 

  
 30 

  
 The Issuers, the
Guarantors and the Initial Purchasers agree that it would not be just and equitable if contribution pursuant to this Section 9 were determined by pro rata allocation (even if the Initial Purchasers were treated as one entity for such purpose)
or by any other method of allocation that does not take account of the equitable considerations referred to in this Section 9. 
 Notwithstanding the provisions of this Section 9, no Initial Purchaser shall be required to contribute any amount in excess of the discount received by such Initial Purchaser in connection with the
Securities distributed by it. No person guilty of fraudulent misrepresentation (within the meaning of Section 11 of the Securities Act) shall be entitled to contribution from any person who was not guilty of such fraudulent misrepresentation.
The Initial Purchasers’ obligations to contribute pursuant to this Section 9 are several, and not joint, in proportion to their respective commitments as set forth opposite their names in Schedule A. For purposes of this Section 9,
each director, officer and employee of an Initial Purchaser and each person, if any, who controls an Initial Purchaser within the meaning of the Securities Act and the Exchange Act shall have the same rights to contribution as such Initial
Purchaser, and each director of either of the Issuers or any Guarantor, and each person, if any, who controls either of the Issuers or any Guarantor within the meaning of the Securities Act and the Exchange Act shall have the same rights to
contribution as the Issuers and the Guarantors, as applicable. 
 SECTION 10. Termination of this Agreement. Prior to the
Closing Date, this Agreement may be terminated by the Representative by notice given to the Partnership if at any time: (i) trading or quotation in any of the Partnership’s securities shall have been suspended or materially limited by the
Commission or by the NYSE, or trading in securities generally on either the Nasdaq Stock Market or the NYSE shall have been suspended or materially limited, or minimum or maximum prices shall have been generally established on any of such quotation
system or stock exchange by the Commission or FINRA; (ii) a general banking moratorium shall have been declared by any of federal, New York or Delaware authorities; or (iii) there shall have occurred any outbreak or escalation of national
or international hostilities involving the United States or any crisis or calamity, or any change in the United States or international financial markets, or any substantial change or development in United States’ or international political,
financial or economic conditions, if the effect of any such event specified in clauses (i) through (iii) is, in the sole judgment of the Representative, so material or adverse as to make it impractical or inadvisable to proceed with the
placement of the Securities with the Subsequent Purchasers on the terms and in the manner contemplated in the Pricing Disclosure Package and the Final Offering Memorandum. Any termination pursuant to this Section 10 shall be without liability
on the part of (i) either Issuer or any Guarantor to any Initial Purchaser, except that the Issuers and the Guarantors shall be obligated to reimburse the expenses of the Initial Purchasers pursuant to Sections 4 and 6 hereof,
(ii) any Initial Purchaser to either of the Issuers or any Guarantor, or (iii) any party hereto to any other party except that the provisions of Sections 8 and 9 hereof shall at all times be effective and shall survive such
termination. 

  
 31 

  
 SECTION 11.
Representations and Indemnities to Survive Delivery. The respective indemnities, agreements, representations, warranties and other statements of the Issuers, the Guarantors, their respective officers and the several Initial Purchasers set
forth in or made pursuant to this Agreement will remain in full force and effect, regardless of any investigation made by or on behalf of any Initial Purchaser, either Issuer, any Guarantor or any of their partners, officers or directors or any
controlling person, as the case may be, and will survive delivery of and payment for the Securities sold hereunder and any termination of this Agreement.

courts of the State of New York in each case located in the City and County of New York (collectively, the “Specified Courts”), and each party irrevocably submits to the exclusive jurisdiction (except for suits, actions, or

 SECTION 17. Default of One or More of the Several Initial
Purchasers. If any one or more of the several Initial Purchasers shall fail or refuse to purchase Securities that it or they have agreed to purchase hereunder on the Closing Date, and the aggregate number of Securities which such defaulting
Initial Purchaser or Initial Purchasers agreed but failed or refused to purchase does not exceed 10% of the aggregate number of the Securities to be purchased on such date, the other Initial Purchasers shall be obligated, severally, in the
proportions that the number of Securities set forth opposite their respective names on Schedule A bears to the aggregate number of Securities set forth opposite the names of all such non-defaulting Initial Purchasers, or in such other proportions as
may be specified by the Initial Purchasers with the consent of the non-defaulting Initial Purchasers, to purchase the Securities which such defaulting Initial Purchaser or Initial Purchasers agreed but failed or refused to purchase on the Closing
Date. If any one or more of the Initial Purchasers shall fail or refuse to purchase Securities and the aggregate number of Securities with respect to which such default occurs exceeds 10% of the aggregate number of Securities to be purchased on the
Closing Date, and arrangements satisfactory to the Initial Purchasers and the Partnership for the purchase of such Securities are not made within 48 hours after such default, this Agreement shall terminate without liability of any party to any other
party except that the provisions of Sections 4, 6, 8 and 9 hereof shall at all times be effective and shall survive such termination. In any such case either the Initial Purchasers or the Issuers shall have the right to postpone the Closing
Date, as the case may be, but in no event for longer than seven days in order that the required changes, if any, to the Final Offering Memorandum or any other documents or arrangements may be effected. 

  
 33 

  
 As used in this
Agreement, the term “Initial Purchaser” shall be deemed to include any person substituted for a defaulting Initial Purchaser under this Section 17. Any action taken under this Section 17 shall not relieve any defaulting
Initial Purchaser from liability in respect of any default of such Initial Purchaser under this Agreement. 
 SECTION 18. No
Advisory or Fiduciary Responsibility. Each of the Issuers and each of the Guarantors acknowledges and agrees that: (i) the purchase and sale of the Securities pursuant to this Agreement, including the determination of the offering price of
the Securities and any related discounts and commissions, is an arm’s-length commercial transaction between the Issuers and the Guarantors, on the one hand, and the several Initial Purchasers, on the other hand, and the Issuers and the
Guarantors are capable of evaluating and understanding and understand and accept the terms, risks and conditions of the transactions contemplated by this Agreement; (ii) in connection with each transaction contemplated hereby and the process
leading to such transaction each Initial Purchaser is and has been acting solely as a principal and is not the agent or fiduciary of any of the Issuers or the Guarantors or their respective Affiliates, equityholders, creditors or employees or any
other party; (iii) no Initial Purchaser has assumed or will assume an advisory or fiduciary responsibility in favor of the Issuers and the Guarantors with respect to any of the transactions contemplated hereby or the process leading thereto
(irrespective of whether such Initial Purchaser has advised or is currently advising the Issuers and the Guarantors on other matters) or any other obligation to the Issuers and the Guarantors except the obligations expressly set forth in this
Agreement; (iv) the several Initial Purchasers and their respective Affiliates may be engaged in a broad range of transactions that involve interests that differ from those of the Issuers and the Guarantors, and the several Initial Purchasers
have no obligation to disclose any of such interests by virtue of any fiduciary or advisory relationship; and (v) the Initial Purchasers have not provided any legal, accounting, regulatory or tax advice with respect to the offering contemplated
hereby, and the Issuers and the Guarantors have consulted their own legal, accounting, regulatory and tax advisors to the extent they deemed appropriate. 
 This Agreement supersedes all prior agreements and understandings (whether written or oral) between the Issuers, the Guarantors and the several Initial Purchasers, or any of them, with respect to the
subject matter hereof. The Issuers and the Guarantors hereby waive and release, to the fullest extent permitted by law, any claims that the Issuers and the Guarantors may have against the several Initial Purchasers with respect to any breach or
alleged breach of fiduciary duty. 

  
 34 

  
 SECTION 19. General
Provisions. This Agreement constitutes the entire agreement of the parties to this Agreement and supersedes all prior written or oral and all contemporaneous oral agreements, understandings and negotiations with respect to the subject matter
hereof. This Agreement may be executed in two or more counterparts, each one of which shall be an original, with the same effect as if the signatures thereto and hereto were upon the same instrument. Delivery of an executed counterpart of a
signature page to this Agreement by telecopier, facsimile or other electronic transmission (e.g., a “pdf” or “tif”) shall be effective as delivery of a manually executed counterpart thereof. This Agreement may not be amended or
modified unless in writing by all of the parties hereto, and no condition herein (express or implied) may be waived unless waived in writing by each party whom the condition is meant to benefit. The section headings herein are for the convenience of
the parties only and shall not affect the construction or interpretation of this Agreement.

All outstanding Common Units and the Incentive Distribution Rights and, in each case, the limited partner interests represented thereby have been duly authorized and validly issued in accordance with the Partnership Agreement, and are fully paid (to
the extent required under the Partnership Agreement) and nonassessable (except as such nonassessability may be affected by Sections 17-303, 17-607 and 17-804 of the Delaware Revised Uniform Limited Partnership Act (the “Delaware LP
Act”)). 

  
 Exhibit A-1-1

  

	 	3.	The General Partner is the sole general partner of (i) the Partnership and owns (of record) a 2.0% general partner interest in the Partnership and
(ii) Genesis Crude Oil, L.P., a Delaware limited partnership (the “Operating Partnership”), and owns (of record) a 0.01% general partner interest in the Operating Partnership. The General Partner owns a non-economic

liens, encumbrances, security interests, charges or claims (i) in respect of which a financing statement under the Uniform Commercial Code of the State of Delaware or the State of Texas (with respect to equity interests owned by Fuel Masters)
naming the General Partner, the Partnership or any Significant Subsidiary as a “debtor” was on file as of October 20, 2010 in the office of the Secretary of State of the State of Delaware or as of October 31, 2010 in the office
of the Secretary of State of the State of Texas (with respect to equity interests owned by Fuel Masters) or (ii) otherwise known to such counsel, in the case of (i) and (ii), other than those (A) created under the Delaware LP Act, the

Documents, (C) created by the Constitutive Documents of the Partnership Entities, or (D) as disclosed in the Preliminary Offering Memorandum and the Final Offering Memorandum. 

 

	 	4.	Except as described in the Preliminary Offering Memorandum and the Final Offering Memorandum or, in the case of transfer restrictions, options to purchase, other rights
to subscribe or to purchase, voting restrictions and preemptive rights, created by the Constitutive Documents of any Partnership Entity, there are no options, warrants, preemptive rights or other rights to subscribe for or to purchase, nor any
restriction upon the voting or transfer of, any equity interests in any Partnership Entity pursuant to any Constitutive Document of any Partnership Entity or any other SEC Document, other than those restrictions upon the transfer of equity interests
created in connection with the Partnership’s or the Significant Subsidiaries’ credit facilities constituting SEC Documents. The offering and sale of the Notes as contemplated in the Purchase Agreement does not give rise under any SEC
Document (as listed on Exhibit C to such counsel’s opinion) to any preemptive right, right of first refusal or other similar right to subscribe for or purchase securities of the Partnership or Finance Corp. 

  
 Exhibit A-1-2

  

	 	5.	The Partnership has all requisite partnership power and authority to issue, sell and deliver the Notes, in accordance with and upon the terms and conditions set forth
in the Purchase Agreement and the Partnership Agreement. Finance Corp has all requisite corporate power and authority to issue, sell and deliver the Notes, in accordance with and upon the terms and conditions set forth in the Purchase Agreement.

  

	 	6.	(a) The execution and delivery of the Transaction Documents by each of the Covered Entities party thereto and the performance by each of the Covered Entities of its
respective obligations under the Transaction Documents to which it is a party has been duly authorized by all necessary corporate or entity action, as applicable, on the part of each of such Covered Entities. 

(b) Each of the Transaction Documents (other than the Exchange Notes) has been duly authorized, executed and delivered by each of the
Covered Entities that is a party to such Transaction Document. 
  

	 	7.	The Partnership Agreement has been duly authorized, executed and delivered by the General Partner and is a valid and legally binding agreement of the General Partner,
enforceable against the General Partner in accordance with its terms. 

  

	 	8.	None of the offering, issuance and sale by the Issuers of the Notes, the execution, delivery and performance by any of the Specified Entities of any of the Transaction
Documents to which such Specified Entity is a party or the performance of the actions required to be taken by any of the Specified Entities pursuant to any of the Transaction Documents to which such Specified Entity is a party conflicts or will
conflict with or constitute or will constitute a breach or violation of or a default (or an event which, with notice or lapse of time or both, would constitute such a default) under, or results or will result in the creation or imposition of any
lien, charge, claim, encumbrance or other security interest upon any property or assets of any of the Partnership Entities (other than those created in connection with the Partnership’s or the Significant Subsidiaries’ credit facilities
constituting SEC Documents) pursuant to, (i) any Constitutive Document of any of the Covered Entities, (ii) any SEC Document, (iii) the Included Laws (including Regulations T, U and X of the Board of Governors of the Federal Reserve
System) or (iv) any order, judgment, decree or injunction of any court or governmental agency or body known to such counsel directed to any of the Partnership Entities or any of their properties in a proceeding to which any of them or their
property is a party; provided, however, that no opinion is expressed pursuant to this paragraph with respect to federal securities laws and other anti-fraud laws. 

  
 Exhibit A-1-3

  

	 	9.	No permit, consent, approval, authorization, order, registration, filing or qualification (“consent”) of or with any court or governmental agency or body
under the Included Laws is required in connection with the offering, issuance and sale by the Issuers of the Notes, the execution, delivery and performance by any of the Specified Entities of any of the Transaction Documents to which such Specified
Entity is a party or the performance of the actions required to be taken by any of the Specified Entities pursuant to any of the Transaction Documents to which such Specified Entity is a party, subject to the assumptions set forth in such
counsel’s opinion, such assumptions to be in form and substance acceptable to the Initial Purchasers, and other than (i) such consents required under state securities or “Blue Sky” laws, (ii) such consents that have been
obtained or made, (iii) filings with the Commission or other consents required in the performance by each of the Specified Entities of its obligations under the Purchase Agreement and (iv) consents required under Federal and state
securities laws as provided in the Registration Rights Agreement. 

  

	 	10.	The statements set forth in the Preliminary Offering Memorandum and the Final Offering Memorandum under the captions “Description of Notes,” “Description
of Existing Indebtedness” and “Certain United States Federal Income Tax Considerations,” insofar as they summarize any agreement, statute or regulation or refer to statements of law or legal conclusions, are accurate and fair
summaries in all material respects. The Notes conform in all material respects to the descriptions thereof contained in the Preliminary Offering Memorandum and the Final Offering Memorandum under the caption “Description of Notes.”

  

	 	11.	None of the Specified Entities is, either before or immediately after giving effect to the offering and sale of the Notes and the receipt of payment for the Notes on
the date hereof as described in the Preliminary Offering Memorandum and the Final Offering Memorandum, required to be registered as an “investment company,” within the meaning of the Investment Company Act. 

 

	 	12.	The Indenture conforms in all material respects to the requirements of the TIA and the rules and regulations of the Commission applicable to an indenture which is
qualified thereunder. 

  

	 	13.	The Notes, when authenticated in accordance with the provisions of the Indenture and delivered to and paid for by the Initial Purchasers in accordance with the terms of

The Exchange Notes, when duly executed, authenticated, issued and delivered as provided in the Indenture and the Registration Rights Agreement, will constitute valid and legally binding obligations of the Issuers, enforceable against the Issuers in
accordance with their respective terms under the Laws of the State of New York. 

  
 Exhibit A-1-4

  

	 	14.	The Indenture (including, with respect to the Guarantors, when the Notes have been duly and validly authenticated in accordance with the terms of the Indenture and duly
and validly paid for by and delivered to the Initial Purchasers in accordance with the terms of the Purchase Agreement, the guarantee of the Guarantors provided for in Article [    ] of the Indenture) constitutes the valid and
legally binding obligation of the Guarantors, enforceable against the Guarantors in accordance with its terms under the Laws of the State of New York. 

  

	 	15.	The Registration Rights Agreement is a valid and binding obligation of each of the Specified Entities, enforceable against the Specified Entities in accordance with its
terms under the Laws of the State of New York. 

  

	 	16.	Assuming without independent investigation, (a) that the Notes are sold to the Initial Purchasers, and initially resold by the Initial Purchasers, in accordance
with the terms of and in the manner contemplated by, the Purchase Agreement and the Final Offering Memorandum; (b) the accuracy of the representations and warranties of the Specified Entities set forth in the Purchase Agreement and the matters
certified in those certain certificates delivered on the date hereof; (c) the accuracy of the representations and warranties of the Initial Purchasers set forth in the Purchase Agreement; (d) the due performance and compliance by the
Specified Entities and the Initial Purchasers of their respective covenants and agreements set forth in the Purchase Agreement; and (e) the Initial Purchasers’ compliance with the Final Offering Memorandum and the transfer procedures and
restrictions described therein, it is not necessary to register the Notes under the Securities Act or to qualify an indenture in respect thereof under the Trust Indenture Act (the “TIA”) in connection with the issuance and
sale of the Notes by the Issuers to the Initial Purchasers or in connection with the offer, resale and delivery of the Notes by the Initial Purchasers in the manner contemplated by the Purchase Agreement and the Final Offering Memorandum, it being
expressly understood that such counsel expresses no opinion in this paragraph (16) or paragraph (9) as to any subsequent offer or resale of any of the Notes. 

Based on our participation in such conferences and conversations, our review of the documents described above, our understanding of the
U.S. federal securities laws and the experience we have gained in our practice thereunder, we advise you that: 
 (a) The
Incorporated Documents, at the time that they were filed (other than the financial statements and other financial and accounting information included in the Incorporated Documents, as to which we express no opinion), appear on their face to comply
as to form in all material respects with the requirements of the Exchange Act except that we express no view as to the antifraud provisions of the Exchange Act. 

  
 Exhibit A-1-5

  
 (b) No information has
come to our attention that causes us to believe that (i) the Pricing Disclosure Package, as of 3:45 P.M. (New York time) on November 12, 2010 (which you have informed us is a time prior to the time of the first sale of the Notes by any
Initial Purchaser), contained or (ii) the Final Offering Memorandum, as of its date and as of the date hereof, contained or contains any untrue statement of a material fact or omitted to state any material fact necessary in order to make the
statements therein, in the light of the circumstances under which they are made, not misleading, except that in the case of each of clauses (i)–(ii) above, we do not express any view as to the financial statements and other financial and
accounting information contained or incorporated by reference therein. 

  
 Exhibit A-1-6

  
 EXHIBIT A-2

 Opinion of local counsel for certain Guarantors to be delivered pursuant to Section 5 of the Purchase Agreement.

 (i) Red River Terminals, L.L.C. is a limited liability company duly organized, validly existing and in good standing under
the laws of the State of Louisiana. TDC, L.L.C. is a limited liability company duly organized, validly existing and in good standing under the laws of the State of Louisiana.

Preliminary Offering Memorandum, the Pricing Supplement, any Issuer Additional Written Communication, or the Final Offering Memorandum (or any amendment or supplement thereto). 

(iii) The execution of the Purchase Agreement by the Partnership, and the consummation of the transactions by the Partnership
contemplated by the Purchase Agreement does not constitute a breach of, or default under, the respective articles of organization of Red River Terminals, L.L.C. and TDC, L.L.C. or the Operating Agreement of TDC, L.L.C. and the Amended and Restated
Operating Agreement of Red River Terminals, L.L.C., as subsidiaries of the Partnership. 
 (iv) The membership interests of Red
River Terminals, L.L.C. and TDC, L.L.C. are validly authorized, issued, fully paid, non-assessable equity interests. 
 (v) The
execution of the Purchase Agreement by the Partnership, and the consummation of the transactions by the Partnership contemplated by the Purchase Agreement do not create any security interest in, or lien, claim, charge or encumbrance upon, any
property or assets, pursuant to the respective articles of organization of Red River Terminals, L.L.C. and TDC, L.L.C., the Amended and Restated Operating Agreement of Red River Terminals, L.L.C., or the laws of the State of Louisiana. 

(vi) The execution of the Purchase Agreement by the Partnership, and the consummation of the transactions by the Partnership contemplated
by the Purchase Agreement, as applicable to Red River Terminals, L.L.C. and TDC, L.L.C., does not constitute a breach of, or default under, any State of Louisiana statute, rule, or regulation of general applicability which, in our experience, is
normally applicable to transactions of the type contemplated by the Purchase Agreement. 

  
 Exhibit A-2-1

  
 EXHIBIT A-3

 Opinion of general counsel for the Partnership to be delivered pursuant to Section 5 of the Purchase Agreement.

 (i) To my knowledge, there are no legal or governmental proceedings pending or threatened to which any of the Issuers or
their subsidiaries is a party or to which any of their respective properties is subject that are required to be described in the Preliminary Offering Memorandum, the Pricing Supplement, any Issuer Additional Written Communication, or the Final
Offering Memorandum (or any amendment or supplement thereto) but are not so described as required. 

  
 Exhibit A-3-1

  
 ANNEX I

 Resale Pursuant to Regulation S or Rule 144A. Each Initial Purchaser understands that: 

Such Initial Purchaser agrees that it has not offered or sold and will not offer or sell the Securities in the United States or to, or
for the benefit or account of, a U.S. Person (other than a distributor), in each case, as defined in Rule 902 of Regulation S (i) as part of its distribution at any time and (ii) otherwise until 40 days after the later of the
commencement of the offering of the Securities pursuant hereto and the Closing Date, other than in accordance with Regulation S or another exemption from the registration requirements of the Securities Act. Such Initial Purchaser agrees that,
during such 40-day restricted period, it will not cause any advertisement with respect to the Securities (including any “tombstone” advertisement) to be published in any newspaper or periodical or posted in any public place and will not
issue any circular relating to the Securities, except such advertisements as are permitted by and include the statements required by Regulation S. 
 Such Initial Purchaser agrees that, at or prior to confirmation of a sale of Securities by it to any distributor, dealer or person receiving a selling concession, fee or other remuneration during the
40-day restricted period referred to in Rule 903 of Regulation S, it will send to such distributor, dealer or person receiving a selling concession, fee or other remuneration a confirmation or notice to substantially the following effect:

 “The Securities covered hereby have not been registered under the U.S. Securities Act of 1933, as amended (the
“Securities Act”), and may not be offered and sold within the United States or to, or for the account or benefit of, U.S. persons (i) as part of your distribution at any time or (ii) otherwise until 40 days after the later of the
date the Securities were first offered to persons other than distributors in reliance upon Regulation S and the Closing Date, except in either case in accordance with Regulation S under the Securities Act (or in accordance with
Rule 144A under the Securities Act or to accredited investors in transactions that are exempt from the registration requirements of the Securities Act), and in connection with any subsequent sale by you of the Securities covered hereby in
reliance on Regulation S under the Securities Act during the period referred to above to any distributor, dealer or person receiving a selling concession, fee or other remuneration, you must deliver a notice to substantially the foregoing
effect. Terms used above have the meanings assigned to them in Regulation S under the Securities Act.” 
 Such Initial
Purchaser agrees that the Securities offered and sold in reliance on Regulation S will be represented upon issuance by a global security that may not be exchanged for definitive securities until the expiration of the 40-day restricted period

Section 2.4 of this Tenth Supplemental Indenture and applicable law, create and issue additional Notes under this Tenth Supplemental Indenture ranking equally and ratably with the outstanding Notes in all respects (or in all respects except for
the payment of interest accruing prior to the issue date of such additional Notes or except for the first payment of interest following the 

  
 10 

 
issue date of such additional Notes) without notice to or the consent of the Holders of outstanding Notes. The initially issued Notes and any additional Notes subsequently issued shall be
consolidated and form a single series with the outstanding Notes for all purposes of this Tenth Supplemental Indenture and shall have the same terms as to status, redemption or otherwise as the outstanding Notes. Any such additional Notes referred
to in this Section 2.2 will be issued under a further supplemental indenture. 
 Nothing contained in this Section 2.2
or elsewhere in this Tenth Supplemental Indenture, or in the Notes, is intended to or shall limit execution by the Company or authentication or delivery by the Trustee of Notes under the circumstances contemplated by Sections 3.03, 3.04, 3.05, 3.06,
9.06, 11.07 and 13.05 of the Senior Indenture. 
 SECTION 2.3. Interest and Interest Rates; Maturity Date of Notes.

 (a) The Notes shall bear interest at 4.125% per annum from November 18, 2010 or from the immediately preceding
Interest Payment Date (as defined below) to which interest has been paid, payable semi-annually in arrears on May 15 and November 15 of each year, commencing May 15, 2011 (each, an “Interest Payment Date”), to the
persons (the “Holders”) in whose name the applicable Notes are registered in the Security Register at the close of business 15 calendar days prior to such Interest Payment Date (i.e., April 30 and October 31,
respectively) (regardless of whether such day is a Business Day, as defined below), as the case may be (each, a “Regular Record Date”). Interest on the Notes shall be computed on the basis of a 360-day year of twelve 30-day months.
Interest, if any, not punctually paid or duly provided for on any Interest Payment Date with respect to a Note (“Defaulted Interest”) shall forthwith cease to be payable to the Holder on the applicable Regular Record Date and may
either be paid to the person in whose name such Note is registered at the close of business on a special record date (the “Special Record Date”) for the payment of such Defaulted Interest to be fixed by the Trustee, notice of which
shall be given to the Holder of such Note not less than ten days prior to such Special Record Date, or may be paid at any time in any other lawful manner, as more particularly described in the Senior Indenture. 

(b) If any Interest Payment Date or Maturity falls on a day that is not a Business Day, the required payment shall be made on the next
Business Day as if it were made on the date such payment was due and no interest shall accrue on the amount so payable for the period from and after such Interest Payment Date or Maturity, as the case may be. 

(c) The Notes shall mature on May 15, 2021 (the “Stated Maturity Date”). 

SECTION 2.4. Limitations on Incurrence of Debt. 
 In addition to the covenants set forth in Article Ten of the Senior Indenture, there are established pursuant to Section 9.01(2) of the Senior Indenture the following covenants for the benefit of the
Holders of the Notes and to which the Notes shall be subject: 

  
 11 

  
 (a) The Company shall
not, and shall not permit any Subsidiary to, Incur any Debt, other than Intercompany Debt, if, immediately after giving effect to the Incurrence of the additional Debt and any other Debt, other than Intercompany Debt, Incurred since the end of the
Latest Completed Quarter prior to the Incurrence of the additional Debt and the application of the net proceeds of the additional Debt and such other Debt, Total Outstanding Debt would exceed 60% of Total Assets, in each case determined as of the
end of such Latest Completed Quarter. 
 (b) The Company shall not, and shall not permit any Subsidiary to, Incur any Secured
Debt, other than Secured Debt that is also Intercompany Debt, if, immediately after giving effect to the Incurrence of the additional Secured Debt and any other Secured Debt, other than Intercompany Debt, Incurred since the end of the Latest
Completed Quarter prior to the Incurrence of the additional Secured Debt and the application of the net proceeds of the additional Secured Debt and such other Secured Debt, the aggregate principal amount of all outstanding Secured Debt is greater
than 50% of Total Assets determined as of the end of such Latest Completed Quarter. 
 (c) The Company shall not, and shall not
permit any Subsidiary to, Incur any Debt, other than Intercompany Debt, if, immediately after giving effect to the Incurrence of the additional Debt, the ratio of Annualized Consolidated EBITDA for the Latest Completed Quarter prior to the
Incurrence of the additional Debt, to Annualized Interest Expense for that quarter would be less than 1.50 to 1.00 on a pro forma basis after giving effect to the Incurrence of the additional Debt and to the application of the net proceeds
therefrom, and calculated on the assumption, without duplication, that: (i) the additional Debt and any other Debt Incurred by the Company, any of its Subsidiaries or any of the Partially-Owned Entities from the first day of that quarter to the
date of determination, which was outstanding at the date of determination, had been Incurred at the beginning of that period and continued to be outstanding throughout that period, and the application of the net proceeds of that Debt, including to
refinance (1) Debt under any revolving credit facility or (2) other Debt, had occurred at the beginning of that period; (ii) the repayment or retirement of any other Debt repaid or retired by the Company, any of its Subsidiaries or
any of the Partially-Owned Entities from the first day of that quarter to the date of determination occurred at the beginning of that period; provided that, except as set forth in clause (i) or (iii) of this Section 2.4(c), in
determining the amount of Debt so repaid or retired, the amount of Debt under any revolving credit facility shall be computed based upon the average daily balance of such Debt during that period; and (iii) in the case of any acquisition or
disposition of any asset or group of assets or the placement of any assets in service or removal of any assets from service by the Company, any of its Subsidiaries or any of the Partially-Owned Entities from the first day of that quarter to the date
of determination, including, without limitation, by merger, or stock or asset purchase or sale, (1) the acquisition, disposition, placement in service or removal from service had occurred as of the first day of that period, with the appropriate
adjustments to Annualized Interest Expense with respect to the acquisition, disposition, placement in service or removal from service being included in that pro forma calculation and (2) the application of the net proceeds from a disposition to
repay or refinance Debt, including, without limitation, Debt under any revolving credit facility, had occurred on the first day of that period. 

  
 12 

  
 (d) The Company and
its Subsidiaries shall maintain at all times Unencumbered Assets of not less than 150% of the aggregate principal amount of all outstanding Unsecured Debt of the Company and its Subsidiaries. 

SECTION 2.5. Optional Redemption. 
 The Notes shall be redeemable, at the option of the Company, in whole at any time or in part from time to time, upon not less than 30 days but not more than 60 days’ prior notice mailed to the
registered address of each Holder of Notes to be so redeemed, at a redemption price equal to (x) if the Notes are redeemed more than 90 days prior to the Stated Maturity Date, the greater of (i) 100% of the principal amount of the Notes to
be redeemed or (ii) the sum of (A) the present values as of the Redemption Date of the remaining scheduled payments of principal and interest thereon from the Redemption Date to the date of Maturity (except for currently accrued but unpaid
interest) discounted to the Redemption Date, on a semi-annual basis (assuming a 360-day year consisting of twelve 30-day months), at the applicable Treasury Yield, plus 30 basis points, plus (B) accrued and unpaid interest to the Redemption
Date or (y) if the Notes are redeemed 90 days or fewer prior to the Stated Maturity Date, 100% of the principal amount of the Notes to be redeemed plus accrued and unpaid interest to the Redemption Date. 

SECTION 2.6. Places of Payment. 
 The Places of Payment where the Notes may be presented or surrendered for payment, where the Notes may be surrendered for registration of transfer or exchange and where notices and demands to and upon the
Company in respect of the Notes and the Senior Indenture may be served shall be in the Borough of Manhattan, The City of New York, and the office or agency for such purpose shall initially be located at c/o The Bank of New York Mellon Trust Company,
N.A., 101 Barclay Street-21W, New York, NY 10286. 
 SECTION 2.7. Method of Payment. 

Payment of the principal of and interest on the Notes shall be made at the office or agency of the Company maintained for that purpose in
the Borough of Manhattan, The City of New York (which shall initially be an office or agency of the Trustee), in such coin or currency of the United States of America as at the time of payment is legal tender for payment of public and private debts;
provided, however, that at the option of the Company, payments of principal and interest on the Notes (other than payments of principal and interest due at Maturity) may be made (i) by check mailed to the address of the Person
entitled thereto as such address shall appear in the Security Register or (ii) by wire transfer to an account maintained by the Person entitled thereto located within the United States. 

SECTION 2.8. Currency. 
 Principal and interest on the Notes shall be payable in Dollars. 

  
 13 

  
 SECTION 2.9. Global
Form. 
 The Notes shall be issuable and transferable in fully registered form as Registered Securities, without coupons.
The Notes shall initially be issued in the form of one or more permanent Global Notes. The depository for the Notes shall be The Depository Trust Company (the “Depositary”). The Notes shall not be issuable in definitive form except
as provided in Section 2.11(a) of this Tenth Supplemental Indenture. 
 SECTION 2.10. Form of Notes and Execution.

 The Notes shall be substantially in the form attached as Exhibit A hereto. The Notes shall be signed in the name and
on the behalf of the Company by the manual or facsimile signature of the Chairman of the Board of Directors, Chief Executive Officer, President, any of its Executive or Senior Vice Presidents, Managing Director, or any of its Vice Presidents
(whether or not designated by a number or numbers or word or words before or after the title “Vice President”). 

SECTION 2.11. Transfer and Exchange. 
 (a) Transfer and Exchange of Global Notes. A Global Note may not be transferred as a whole except by the Depositary to a nominee of the Depositary, by a nominee of the Depositary to the Depositary
or to another nominee of the Depositary, or by the Depositary or any such nominee to a successor Depositary or a nominee of such successor Depositary. All Global Notes shall be exchanged by the Company for Definitive Notes if (i) the Company
delivers to the Trustee notice from the Depositary stating that it is unwilling or unable to continue to act as a clearing agency for the Notes or is no longer a clearing agency registered under the Exchange Act or other applicable law and, in
either case, a successor Depositary is not appointed by the Company within 90 days after the date of such notice; or (ii) the Company in its sole discretion determines that the Global Notes (in whole but not in part) should be exchanged for
Definitive Notes and delivers a written notice to such effect to the Trustee. Upon the occurrence of any of the preceding events, Definitive Notes shall be issued in such names as the Depositary shall instruct the Trustee. 

(b) Transfer of Beneficial Interests in the Global Notes. The transfer of beneficial interests in the Global Notes shall be
effected through the Depositary in accordance with the provisions of the Senior Indenture and the applicable procedures of the Depositary. 
 (c) Exchange of Beneficial Interests in Global Notes for Definitive Notes. A holder of a beneficial interest in a Global Note may, in the circumstances described in Section 2.11(a), have such
beneficial interest exchanged by the Company for a Definitive Note. 
 The transferor of a beneficial interest in a Global Note
must deliver to the Security Registrar (1) a written order from a Participant or an Indirect Participant given to the Depositary in accordance with the Applicable Procedures directing the Depositary to cause to be issued a Definitive Note in an
amount equal to the beneficial interest to be 

  
 14 

 
exchanged and (2) instructions given by the Depositary to the Security Registrar containing information regarding the Person in whose name such Definitive Note shall be registered to effect
the exchange. In any such case, the Trustee shall cause the aggregate principal amount of the applicable Global Note to be reduced accordingly pursuant to Section 2.11(e) hereof, and the Company shall execute and the Trustee, upon receipt of a
Company Order in accordance with the Senior Indenture, shall authenticate and deliver to the Person designated in the instructions a Definitive Note in the appropriate principal amount. Any Definitive Note issued in exchange for a beneficial
interest in a Global Note pursuant to this Section 2.11(c) shall be registered in such name or names and in such authorized denomination or denominations as the holder of such beneficial interest shall instruct the Security Registrar through
instructions from the Depositary and the Participant or Indirect Participant. The Trustee shall deliver such Definitive Notes to the Persons in whose names such Notes are so registered. 

(d) Transfer of Definitive Notes. Upon request by a Holder of Definitive Notes, the Security Registrar shall register the transfer
of Definitive Notes. Prior to such registration of transfer, the requesting Holder shall present or surrender to the Security Registrar the Definitive Notes duly endorsed or accompanied by a written instruction of transfer in form satisfactory to
the Security Registrar duly executed by such Holder or by his attorney, duly authorized in writing. 
 (e) Cancellation
and/or Adjustment of Global Notes. At such time as all beneficial interests in a particular Global Note have been exchanged for Definitive Notes or a particular Global Note has been redeemed, repurchased or canceled in whole and not in part,
each such Global Note shall be returned to or retained and canceled by the Trustee in accordance with the terms of the Senior Indenture. At any time prior to such cancellation, if any beneficial interest in a Global Note is exchanged for or
transferred to a Person who will take delivery thereof in the form of a beneficial interest in another Global Note or for Definitive Notes, the principal amount of Notes represented by such Global Note shall be reduced accordingly and an endorsement
shall be made on such Global Note by the Trustee or by the Depositary to reflect such reduction; and if the beneficial interest is being exchanged for or transferred to a Person who will take delivery thereof in the form of a beneficial interest in
another Global Note, such other Global Note shall be increased accordingly and an endorsement shall be made on such Global Note by the Trustee or by the Depositary to reflect such increase. 

SECTION 2.12. General Provisions Relating to Transfers and Exchanges. 

(a) The Trustee and the Security Registrar will retain copies of all certificates, opinions and other documents received in connection
with the transfer or exchange of a Note (or a beneficial interest therein), and the Company will have the right to inspect and make copies thereof at any reasonable time upon written notice to the Trustee or the Security Registrar, as the case may
be. 
 (b) Each Holder of a Note agrees to indemnify the Company and the Trustee against any liability that may result from the
transfer, exchange or assignment of such 

  
 15 

 
Holder’s Note in violation of any provision of this Tenth Supplemental Indenture or applicable United States federal or state securities law. 

(c) The Trustee shall have no obligation or duty to monitor, determine or inquire as to compliance with any restrictions on transfer
imposed under this Tenth Supplemental Indenture or under applicable law with respect to any transfer of any interest in any Note (including any transfers between or among members of, or Participants or Indirect Participants in, the Depositary or
beneficial owners of interests in any Global Note) other than to require delivery of such certificates and other documentation or evidence as are expressly required by, and to do so if and when expressly required by the terms of, this Tenth
Supplemental Indenture, and to examine the same to determine substantial compliance as to form with the express requirements hereof. 
 SECTION 2.13. Registrar and Paying Agent. 
 The Trustee shall initially
serve as Security Registrar and Paying Agent for the Notes. 
 SECTION 2.14. Defeasance. 

The provisions of Sections 14.02 and 14.03 of the Senior Indenture, together with the other provisions of Article Fourteen of the Senior
Indenture, shall be applicable to the Notes. The provisions of Section 14.03 of the Senior Indenture shall apply to the covenants set forth in Sections 2.4 and 2.15 of this Tenth Supplemental Indenture and to those covenants specified in
Section 14.03 of the Senior Indenture. 
 SECTION 2.15. Provision of Financial Information. 

Whether or not the Company is subject to Section 13 or 15(d) of the Exchange Act, the Company shall, to the extent permitted under
the Exchange Act, file with the Commission the annual reports, quarterly reports and other documents which the Company would have been required to file with the Commission pursuant to such Section 13 or 15(d) if the Company were so subject,
such documents to be filed with the Commission on or prior to the respective dates (the “Required Filing Dates”) by which the Company would have been required so to file such documents if the Company were so subject. 

The Company shall also in any event (x) within 15 days of each Required Filing Date (i) if the Company is not then subject to
Section 13 or 15(d) of the Exchange Act, transmit by mail to all Holders, as their names and addresses appear in the Security Register, without cost to such Holders, copies of the annual reports and quarterly reports which the Company would
have been required to file with the Commission pursuant to Section 13 or 15(d) of the Exchange Act if the Company were subject to such Sections, and (ii) file with the Trustee copies of annual reports, quarterly reports and other documents
which the Company would have been required to file with the Commission pursuant to Section 13 or 15(d) of the Exchange Act if the Company were subject to such Sections and (y) if filing such documents by the Company with the Commission is
not 

  
 16 

 
permitted under the Exchange Act, promptly upon written request and payment of the reasonable cost of duplication and delivery, supply copies of such documents to any prospective Holder.

 Delivery of such reports, information and documents to the Trustee is for informational purposes only and the Trustee’s
receipt of such shall not constitute constructive notice of any information contained therein or determinable from information contained therein, including the Company’s compliance with any of its covenants hereunder (as to which the Trustee is
entitled to rely exclusively on Officers’ Certificates). 
 SECTION 2.16. Waiver of Certain Covenants.

(except any such term, provision or condition which could not be amended without the consent of all Holders of the Notes), if before or after the time for such compliance the Holders of at least a majority in principal amount of all outstanding
Notes, by Act of such Holders, either waive such compliance in such instance or generally waive compliance with such covenant or condition. Except to the extent so expressly waived, and until such waiver shall become effective, the obligations of
the Company and the duties of the Trustee in respect of any such term, provision or condition shall remain in full force and effect.

Senior Indenture shall not be applicable to the Notes.

the Holder of this Note (as indicated below) is The Depository Trust Company (“DTC”) or a nominee of DTC, insert: Unless this Note is presented by an authorized representative of The Depository Trust Company, a New York corporation

any payment is made to Cede & Co. or to such other entity as is requested by an authorized representative of DTC), ANY TRANSFER, PLEDGE OR OTHER USE HEREOF FOR VALUE OR OTHERWISE BY OR TO ANY PERSON IS WRONGFUL, inasmuch as the registered

	CUSIP No. 10112R AS3	 	

 BOSTON PROPERTIES LIMITED PARTNERSHIP, a Delaware limited partnership (herein referred to as the
“Company,” which term includes any successor corporation under the Indenture referred to on the reverse hereof), for value received, hereby promises to pay to CEDE & CO. or registered assigns the principal sum of
             Dollars ($            ) on May 15, 2021 (the “Stated Maturity Date”) or
earlier at the option of the Company as provided herein (the “Redemption Date”) and to pay interest thereon from November 18, 2010 or from the most recent Interest Payment Date to which interest has been paid or duly provided
for, semi-annually on May 15 and November 15 in each year (each, an “Interest Payment Date”), commencing May 15, 2011, at the rate of 4.125% per annum, until the principal hereof is paid or duly provided for. The
interest so payable, and punctually paid or duly provided for, on any Interest Payment Date will, as provided in such Indenture, be paid to the Holder in whose name this Note (or one or more Predecessor Securities) is registered at the close of
business on the Regular Record Date for such interest, which shall be the April 30 or October 31 (whether or not a Business Day), as the case may be, next preceding such Interest Payment Date at the office or agency of the Company
maintained for such purpose; 

 
provided, however, that such interest may be paid, at the Company’s option, by mailing a check to such Holder at its registered address or by transfer of funds to an account
maintained by such Holder within the United States. Any such interest not so punctually paid or duly provided for shall forthwith cease to be payable to the Holder on such Regular Record Date, and may be paid to the Holder in whose name this Note
(or one or more Predecessor Securities) is registered at the close of business on a Special Record Date for the payment of such Defaulted Interest to be fixed by the Trustee, notice whereof shall be given to Holders of Notes of this series not less
than 10 days prior to such Special Record Date, or may be paid at any time in any other lawful manner not inconsistent with the requirements of any securities exchange on which the Notes of this series may be listed, and upon such notice as may be
required by such exchange, all as more fully provided in the Indenture. Interest will be computed on the basis of a 360-day year of twelve 30-day months. 
 The principal of this Note payable on the Stated Maturity Date or the principal of, premium or Make-Whole Amount, if any, and, if the Redemption Date is not an Interest Payment Date, interest on this Note
payable on the Redemption Date, will be paid against presentation of this Note at the office or agency of the Company maintained for that purpose in the Borough of Manhattan, The City of New York, in such coin or currency of the United States of
America as at the time of payment is legal tender for the payment of public and private debts. 
 Interest payable on this Note
on any Interest Payment Date and on the Stated Maturity Date or Redemption Date, as the case may be, will include interest accrued from and including the next preceding Interest Payment Date in respect of which interest has been paid or duly
provided for (or from and including November 18, 2010, if no interest has been paid on this Note) to but excluding such Interest Payment Date or the Stated Maturity Date or Redemption Date, as the case may be. If any Interest Payment Date or
the Stated Maturity Date or Redemption Date falls on a day that is not a Business Day, as defined below, principal, premium or Make-Whole Amount, if any, and/or interest payable with respect to such Interest Payment Date or Stated Maturity Date or
Redemption Date, as the case may be, will be paid on the next succeeding Business Day with the same force and effect as if it were paid on the date such payment was due, and no interest shall accrue on the amount so payable for the period from and
after such Interest Payment Date or Stated Maturity Date or Redemption Date, as the case may be. “Business Day” means any day, other than a Saturday or Sunday, that is neither a legal holiday nor a day on which banking institutions
in The City of New York are required or authorized by law, regulation or executive order to close. 
 All payments of principal,
premium or Make-Whole Amount, if any, and interest in respect of this Note will be made by the Company in immediately available funds. 
 Reference is hereby made to the further provisions of this Note set forth on the reverse hereof, which further provisions shall for all purposes have the same effect as if set forth at this place.

  
 Unless the Certificate
of Authentication hereon has been executed by the Trustee by manual signature of one of its authorized signatories, this Note shall not be entitled to any benefit under the Indenture, or be valid or obligatory for any purpose. 

  
 IN WITNESS WHEREOF,
the Company has caused this Note to be duly executed.

 REVERSE OF NOTE

 BOSTON PROPERTIES LIMITED PARTNERSHIP 
 This Note is one of a duly authorized issue of securities of the Company (herein called the “Notes”), issued and to be issued in one or more series under an Indenture, dated as of
December 13, 2002, as supplemented by Supplemental Indenture No. 10, dated as of November 18, 2010 (as so supplemented, herein called the “Indenture”), each between the Company and The Bank of New York Mellon Trust
Company, N.A. (formerly known as The Bank of New York Trust Company, N.A.), as Trustee (herein called the “Trustee,” which term includes any successor trustee under the Indenture with respect to the series of which this Note is a
part), to which Indenture and all indentures supplemental thereto reference is hereby made for a statement of the respective rights, limitations of rights, duties and immunities thereunder of the Company, the Trustee and the Holders of the Notes,
and of the terms upon which the Notes are, and are to be, authenticated and delivered. The aggregate principal amount of the Notes to be issued under such series is initially limited to $850,000,000 (except for Notes authenticated and delivered upon
transfer of, or in exchange for, or in lieu of other Notes). All terms used in this Note which are defined in the Indenture shall have the meanings assigned to them in the Indenture. 

If an Event of Default, as defined in the Indenture, with respect to the Notes shall occur and be continuing, the principal of the Notes
of this series may be declared due and payable in the manner and with the effect provided in the Indenture. 
 The Notes are
subject to redemption, at the option of the Company, in whole at any time or in part from time to time, at a redemption price equal to (x) if the Notes are redeemed more than 90 days prior to the Stated Maturity Date, the greater of
(i) 100% of the principal amount of the Notes to be redeemed or (ii) the sum of (A) the present values as of the Redemption Date of the remaining scheduled payments of principal and interest thereon from the Redemption Date to the
date of Maturity (except for currently accrued but unpaid interest) discounted to the Redemption Date, on a semi-annual basis (assuming a 360-day year consisting of twelve 30-day months), at the applicable Treasury Yield, plus 30 basis points (the
“Make-Whole Amount”), plus (B) accrued and unpaid interest to the Redemption Date or (y) if the Notes are redeemed 90 days or fewer prior to the Stated Maturity Date, 100% of the principal amount of the Notes to be
redeemed plus accrued and unpaid interest to the Redemption Date. 
 Notice of redemption will be given by first-class mail to
Holders of Notes, not less than 30 nor more than 60 days prior to the Redemption Date, all as provided in the Indenture. 
 In
the event of redemption of this Note in part only, a new Note or Notes for the unredeemed portion hereof shall be issued in the name of the Holder hereof upon the cancellation hereof. 

  
 The Indenture permits,
with certain exceptions as therein provided, the amendment thereof and the modification of the rights and obligations of the Company and the rights of the Holders of the Notes under the Indenture at any time by the Company and the Trustee with the
consent of the Holders of not less than a majority of the aggregate principal amount of all Notes issued under the Indenture at the time Outstanding and affected thereby. The Indenture also contains provisions permitting the Holders of not less than
a majority of the aggregate principal amount of the Outstanding Notes, on behalf of the Holders of all such Notes, to waive compliance by the Company with certain provisions of the Indenture. Furthermore, provisions in the Indenture permit the
Holders of not less than a majority of the aggregate principal amount, in certain instances, of the Outstanding Notes of any series to waive, on behalf of all of the Holders of Notes of such series, certain past defaults under the Indenture and
their consequences. Any such consent or waiver by the Holder of this Note shall be conclusive and binding upon such Holder and upon all future Holders of this Note and other Notes issued upon the registration of transfer hereof or in exchange
herefor or in lieu hereof, whether or not notation of such consent or waiver is made upon this Note. 
 No reference herein to
the Indenture and no provision of this Note or of the Indenture shall alter or impair the obligation of the Company, which is absolute and unconditional, to pay the principal of (and premium or Make-Whole Amount, if any) and interest on this Note at
the times, places and rate, and in the coin or currency, herein prescribed. 
 As provided in the Indenture and subject to
certain limitations therein set forth, the transfer of this Note is registrable in the Security Register of the Company upon surrender of this Note for registration of transfer at the office or agency of the Company in any place where the principal
of (and premium or Make-Whole Amount, if any) and interest on this Note are payable, duly endorsed by, or accompanied by a written instrument of transfer in form satisfactory to the Company and the Security Registrar duly executed by, the Holder
hereof or by his attorney duly authorized in writing, and thereupon one or more new Notes, of authorized denominations and for the same aggregate principal amount, will be issued to the designated transferee or transferees. 

As provided in the Indenture and subject to certain limitations therein set forth, this Note is exchangeable for a like aggregate
principal amount of Notes of different authorized denominations but otherwise having the same terms and conditions, as requested by the Holder hereof surrendering the same. 
 The Notes of this series are issuable only in registered form without coupons in denominations of $1,000 and any integral multiple thereof. 

No service charge shall be made for any such registration of transfer or exchange, but the Company may require payment of a sum
sufficient to cover any tax or other governmental charge payable in connection therewith. 
 Prior to due presentment of this
Note for registration of transfer, the Company, the Trustee and any agent of the Company or the Trustee may treat the Person in whose 

 
name this Note is registered as the owner hereof for all purposes, whether or not this Note be overdue, and neither the Company, the Trustee nor any such agent shall be affected by notice to the
contrary. 
 No Holder shall have any recourse under or upon any obligation, covenant or agreement contained in the Indenture,
or any indenture supplemental thereto, or this Note, or because of any indebtedness evidenced hereby or thereby, including the payment of the principal of or premium or Make-Whole Amount, if any, or the interest on this Note, or for any claim based
hereon or thereon, or otherwise in respect hereof or thereof, against (i) Boston Properties or any other past, present or future partner in the Company, (ii) any other person or entity which owns an interest, directly or indirectly, in any
partner of the Company, or (iii) any past, present or future stockholder, employee, officer or director, as such, of the Company or Boston Properties or any successor under any rule of law, statute or constitutional provision or by the
enforcement of any assessment or by any legal or equitable proceeding or otherwise. Each Holder of this Note, by the acceptance hereof and as part of the consideration for the issue hereof, expressly waives and releases all such liability. The
waiver and release are part of the consideration for the issue of the Note. 
 The Indenture and the Notes shall be governed by
and construed in accordance with the laws of the State of New York applicable to agreements made and to be performed entirely in such State.
