 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”), propose to issue and sell to Wells Fargo Securities, LLC (“Wells
Fargo”) 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 $350,000,000 aggregate principal
amount of the Partnership’s 5.750% Senior Notes due 2021 (the “Notes”). Wells Fargo 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
February 8, 2013 (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 initially only in global form in
the name of Cede & Co., as nominee of The Depository Trust Company (the “Depositary”) pursuant to a letter of representations dated November 17, 2010 (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
February 8, 2013 (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.” 
 This Agreement, the Registration Rights Agreement, the DTC Agreement, the Securities, the Exchange Securities 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 herein, all or a portion of the Securities to purchasers (the “Subsequent
Purchasers”) on the terms set forth in the Pricing Disclosure Package (the first time when sales of the Securities are made is referred to as the “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 S”)). 
 The Issuers have prepared and delivered to each Initial Purchaser copies of a Preliminary Offering Memorandum, dated February 5, 2013 (the “Preliminary Offering Memorandum”), and
have prepared and delivered to each Initial Purchaser copies of a Pricing Supplement, dated February 5, 2013 (the “Pricing Supplement”), describing the terms of the Securities, each for use by such Initial Purchaser in
connection with its solicitation of offers to purchase the Securities. The Preliminary Offering Memorandum and the Pricing Supplement are herein referred to as the “Pricing Disclosure Package.” Promptly after this Agreement is
executed and delivered, the Issuers will prepare and deliver to each Initial Purchaser a final offering memorandum dated the date hereof (the “Final Offering Memorandum”).

Securities Act, to the extent applicable. The interactive data in eXtensible Business Reporting Language (“XBRL”) incorporated by reference in the Preliminary Offering Memorandum and the Offering Memorandum fairly presents the information

either of the Issuers or any of their respective Subsidiaries. 
 (q) 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. 

(r) 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. 

(s) 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. 

  
 12 

 (t) 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 of them, in each
case free and clear of any security interests, mortgages, liens, encumbrances, equities, claims and other defects (except as may exist under applicable law and as may be imposed under the Partnership’s or a Subsidiary’s 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. 

(u) Tax Law Compliance. 
 (i) The Partnership met for the taxable year ended December 31, 2011, and the Partnership expects to meet for the taxable year ending December 31, 2012, 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. 

(v) Issuers and Guarantors Not an “Investment Company.” Neither of the Issuers nor any Guarantor is, or
after receipt of payment for the Securities 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). 
 (w) 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 

  
 13 

 
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. 

(x) 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. 
 (y) Solvency. The Partnership
and each of the Guarantors 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. 
 (z) 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.

 (aa) 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; 

  
 14 

 
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.

 (bb) 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. 

(cc) 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). 

  
 15 

 (dd) 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. 
 (ee) 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 Guarantors, (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. 

  
 16 

 (ff) 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. 
 (gg) 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. 
 (hh) No Conflict with OFAC Laws. None of the Issuers, any of their Subsidiaries or Cameron nor, to the knowledge of the Issuers, any director, officer, agent, employee, Affiliate or person acting
on behalf of the Issuers, their Subsidiaries or Cameron is currently subject to any U.S. sanctions administered by the Office of Foreign Assets Control of the U.S. Treasury Department (“OFAC”). 

(ii) 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. 
 (jj) Certain Statements. The statements set forth in the Offering Memorandum under the caption “Certain United States Federal Income Tax Considerations,” insofar as they purport to
describe the provisions of the laws and documents referred to therein, are accurate, complete and fair. 

  
 17 

 (kk) 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
action, order or decree, otherwise than as set forth or contemplated in the Offering Memorandum; and, since the respective dates as of which information is given in the Offering Memorandum, there has not been any change in the capital stock or
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. 

(ii) Except as set forth in or contemplated by the Partnership SEC Documents, since December 31, 2011, each of the
Issuers and each of the Guarantors have conducted their business in the ordinary course, consistent with past practice, and there has been no (i) change that has had or would reasonably be expected to have a Material Adverse Effect,
(ii) acquisition or disposition of any material asset by the Issuers or any of the Guarantors or any contract or arrangement therefor, otherwise than for fair value in the ordinary course of business, (iii) material change in the
Partnership’s accounting principles, practices or methods or (iv) incurrence of material indebtedness

 Any certificate signed by an officer of either of the Issuers or any Guarantor
and delivered to the Initial Purchasers or to counsel for the Initial Purchasers shall be deemed to be a representation and warranty by the applicable Issuer or such Guarantor to each Initial Purchaser as to the matters set forth therein.

 (c) Delivery of the
Securities. The Partnership shall deliver, or cause to be delivered, through the facilities of the Depositary, to Wells Fargo for the accounts of the several Initial Purchasers certificates for the Securities at the Closing Date against the
irrevocable release of a wire transfer of immediately available funds for the amount of the purchase price therefor. The certificates for the Securities shall be in global form and in such denominations and registered in the name of Cede &

and 
 (iii) it will not offer or sell Securities by, any form of general solicitation or general advertising,
including but not limited to the methods described in Rule 502(c) under the Securities Act. 
 SECTION 3. Additional
Covenants. Each of the Issuers and the Guarantors further covenants and agrees, jointly and severally, with each Initial Purchaser as follows: 
 (a) Preparation of Final Offering Memorandum; Initial Purchasers’ Review of Proposed Amendments and Supplements and Issuer Additional Written Communications. As promptly as practicable
following the Time of Sale and in any 

  
 19 

 
event not later than the second business day following the date hereof, the Issuers will prepare and deliver to the Initial Purchasers the Final Offering Memorandum, which shall consist of the
Preliminary 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 Issuers will not amend or supplement the Final Offering Memorandum prior to the Closing Date 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 Final Offering Memorandum). Before making, preparing, using, authorizing, approving or distributing any Issuer Additional Written Communication, the Partnership will furnish to the Representative a copy of such written communication
for review and will not make, prepare, use, authorize, approve or distribute any such written communication to which the Representative reasonably object in writing (unless the Issuers are advised by counsel that they are required by law to so amend
or supplement such written communication). 
 (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 their own expense to the Initial Purchasers, amendments or
supplements to the Final Offering 

  
 20 

 
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 at the time of sale of
Securities, be misleading or so that the Final Offering Memorandum, as amended or supplemented, will comply with all applicable law. 
 (c) Copies of the Offering Memorandum. The Issuers agree to furnish the Initial Purchasers, without charge, as many copies of the Pricing Disclosure Package and the Final Offering Memorandum
(exclusive of the Incorporated Documents) and any amendments and supplements thereto as they shall reasonably request.

qualifying or registering) all or any part of the Securities for offer and sale under the securities laws of the several states of the United States or any other jurisdictions reasonably designated by the Representative, shall comply with such laws
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. 

(e) Use of Proceeds. The Issuers shall apply the net proceeds from the sale of the Securities in the manner
described under the caption “Use of Proceeds” in the Pricing Disclosure Package. 
 (f) The
Depositary. The Issuers will cooperate with the Initial Purchasers and use their reasonable best efforts to permit the Securities to be eligible for clearance and settlement through the facilities of the Depositary. 

(g) Additional Issuer Information. Prior to the completion of the placement of the Securities by the Initial
Purchasers with the Subsequent Purchasers, the Partnership shall file, on a timely 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 their expense, upon request, to holders and beneficial owners of Securities and prospective purchasers of Securities information satisfying the requirements of Rule 144A(d) under the
Securities Act. 

  
 21 

 (h) Agreement Not To Offer or Sell Additional Securities. During the
period of 60 days following the date hereof, the Issuers will not, without the prior written consent of Wells Fargo (which consent may be withheld at the sole discretion of Wells Fargo), 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(a)(2) thereof or by Rule 144A or by Regulation S thereunder or otherwise. 

(j) No General Solicitation or Directed Selling Efforts. The Issuers agree that they will not and will not permit
any of their Affiliates or any other person acting on its or their behalf (other than the Initial Purchasers, as to which no 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(a)(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. 
 (l) Legended Securities. Each certificate for a Security will bear the legend contained in “Notice to Investors” in the Preliminary Offering Memorandum for the time period and upon the
other terms stated in the Preliminary Offering Memorandum. 
 The Representative, on behalf of the several Initial Purchasers,
may, in its sole discretion, waive in writing the performance by the Issuers or any Guarantor of any one or more of the foregoing covenants or extend the time for their performance. 

  
 22

in the business, properties, management, condition (financial or otherwise) or results of operations of the Partnership, Finance Corp. and the Guarantors, taken as a whole, the effect of which change or development is, in the sole judgment of the
Representative, so material and 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; and 
 (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

covenants of the Issuers and the Guarantors set forth in Section 1 hereof were true and correct as of the Time of Sale and are true and correct as of the Closing Date with the same force and effect as though expressly made on and as of the

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

 25 

 SECTION 7. Offer, Sale and Resale Procedures. Each of the Initial Purchasers, on the
one hand, and 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 to Subsequent Purchasers 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 to Subsequent Purchasers 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. 
 (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 

  
 26 

 
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.” 

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. 

  
 27 

 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 Wells Fargo) 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. 
 (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

  
 28 

 
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 second sentence of the third paragraph, the second sentence of the fourth paragraph, the second sentence of the sixth, the first and fifth sentences of the seventh paragraph and the third and fourth sentences of the
fourteenth 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. 
 (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

  
 29 

 
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 Wells Fargo (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.

 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 

  
 30 

 
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. 

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. 

  
 31 

 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. 

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.

Proceeding in the Specified Courts and irrevocably and unconditionally waive and agree not to plead or claim in any Specified Court that any Related Proceeding brought in any Specified Court has been brought in an inconvenient forum. Each party not
located in the United States irrevocably appoints CT Corporation System as its agent to receive service of process or other legal summons for purposes of any Related Proceeding that may be instituted in any Specified Court. 

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. 
 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 

  
 34 

 
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. 
 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.

Units and Waiver Units and, in each case, 

  
 Exhibit A-1-1

	 	
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”)).

  

	 	3.	The General Partner (i) is the sole general partner of the Partnership and owns (of record) a non-economic general partner interest in the Partnership,
(ii) is the sole general partner of 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 and

that are Delaware limited liability companies, as such nonassessability may be affected by Sections 18-607 and 18-804 of the Delaware Limited Liability Company Act (the “Delaware LLC Act”), or (z) with respect to Fuel
Masters, as such nonassessability may be affected by Sections 101.206 and 101.613 of the Texas Business Organizations Code (the “Texas BOC”)), and, in each case, is owned as specified in the two preceding sentences, free and
clear of all 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 January , 2013 in the office of the Secretary of State of the State of Delaware or as of January , 2013 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
Delaware LLC Act, the Delaware General Corporation Law (the “DGCL”) or the Texas BOC, (B) created in connection with the Partnership’s or the Significant Subsidiaries’ credit facilities constituting SEC
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. 

  
 Exhibit A-1-2

	 	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. 

 

	 	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

	 	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 

  
 Exhibit A-1-3

 
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. 
  

	 	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 Certain Other 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. 

  
 Exhibit A-1-4

	 	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 Purchase Agreement, will be valid and legally binding obligations of the Issuers, entitled to the benefits of the Indenture and enforceable against the Issuers in accordance with their respective terms under the Laws of the State of New York.
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. 

  

	 	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 in respect of the Notes provided for in Article 10 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. 

  
 Exhibit A-1-5

 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, the notes and schedules thereto 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. 
 (b) No information has come to our attention that causes us to believe that (i) the Pricing Disclosure Package, as
of 4:10 P.M. (New York time) on February 5, 2013 (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, the notes and schedules thereto 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

Terminals, L.L.C. and TDC, L.L.C. has the power and authority to own its respective properties and conduct its business in each case in all material respects, as 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). 
 (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

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

 (c) In the event that the Compensation Committee of the Board of Directors
of Parker Drilling approves annual grants of restricted stock units to other executives under the LTIP (as hereinafter defined), which grants are scheduled to be awarded in March, 2013 (the “2013 Awards”), Executive shall receive grants of
restricted stock units commensurate with the position of CFO of Parker Drilling at the same time as the other participants receive such grants. On the Termination Date, the 2013 Awards shall vest on a Pro Rata Basis pursuant to Section 5(b)
hereof. 
 (d) In the event that the Compensation Committee of the Board of Directors of Parker Drilling approves
2012 annual cash bonuses to other executives under the Parker Drilling Company Incentive Compensation Plan (As Amended and Restated Effective January 1, 2009), which payouts are scheduled to be awarded in March, 2013, Executive shall receive at
the same time as the other participants a cash bonus for 2012 based on the same corporate scorecard applied to other senior executives and using an individual performance factor of 0.75. 

4. Severance Payment. On the date that the Waiver and Release referenced in Section 10 and attached hereto as Appendix A
becomes irrevocable by Executive (defined as the Waiver Effective Date in the Waiver and Release), Parker Drilling shall pay to Executive a lump sum amount equal to the sum of (a) $864,583 (which is 1.5 multiplied by “Total Cash”
under Section 6(a)(1) of the Employment Agreement) plus (b) 39,752 forfeited RSUs multiplied by the closing price for the Company’s common stock on the Termination Date (currently estimated to be $221,021)1. 

 

	 	5.	Vesting of Restricted Stock on Pro Rata Basis. 

 (a) Executive is the recipient of certain Parker Drilling restricted stock units that are not vested as of the Effective Date (“Grant Units”), which Grant Units are listed on Appendix A to this
Agreement. Parker Drilling granted the Grant Units to Executive pursuant to certain award agreements (the “Restricted Stock Award Agreements”), the Parker Drilling Company 2010 Long-Term Incentive Plan, and the Parker Drilling Company

(60) days after the Termination Date, the Company shall deliver to Grantee a number of shares of Parker Drilling common stock equal to the number of Grant Units designated on Appendix A as vested on a Pro Rata Basis as of the Termination Date.

 (b) On the Termination Date, the 2013 Awards, excluding performance-based components,
shall vest on a Pro Rata Basis, such that 2/36ths of the
number of Restricted Stock Units in the 2013 Awards shall become fully vested and transferable to Executive free of any and all restrictions as of the Termination Date. All 2013 Awards that remain unvested as of the Termination Date, including
performance-based components, shall be forfeited by Executive as of the Termination Date.

	6.	Group Health Coverage. 

 (a) Parker Drilling shall provide to Executive and his covered dependents, if any, coverage as in effect for Executive on the date immediately prior to the Termination Date under Parker Drilling’s
group health plan and group dental plan for a period of twenty-four (24) months following the Termination Date; provided, however, Executive and his covered dependents, if any, shall not be required to pay any portion of the premium cost to
retain such coverages except that the cost of such coverages will be imputed as income and reported as wages to Executive in the event that Parker Drilling maintains a self-funded group health plan and/or group dental plan and such Parker Drilling
-provided coverage would otherwise be discriminatory within the meaning of Section 105(h) of the Internal Revenue Code of 1986, as amended (the “Code”). In all other respects, Executive shall be treated the same as other participants
under the terms of such plans. 
 (b) Thereafter, Executive and his covered dependents, if any, shall be entitled
to elect continuation coverage under such plans pursuant to the Consolidated Omnibus Budget Reconciliation Act of 1985, as amended (“COBRA”), and Parker Drilling’s procedures for COBRA administration (“COBRA Coverage”). In
the event that COBRA Coverage is elected, (i) the COBRA time period shall not be reduced by the post-termination continuation coverage provided pursuant to Section 6(a) and (ii) Executive (and his covered dependents, if any) must pay
the full COBRA premium rates as effective during the COBRA Coverage period. In the event Executive does not execute and deliver the Waiver and Release described in Section 10, Executive and his covered dependents, if any, shall be entitled to
only COBRA Coverage after the Termination Date. 
 (c) In the event of any change to the group health plan or
group dental plan following the Termination Date, Executive shall be treated consistently with senior officers of the Company (or its successor) with respect to the terms and conditions of coverage and other substantive provisions of the plan;
provided, however, no participant contributions shall be required from Executive (and his covered dependents, if any) unless COBRA Coverage is in effect. Notwithstanding the foregoing provisions of this Section 6(c), the coverage of Executive
(and his dependents, if any) under such health and/or dental plans maintained by the Company shall terminate in the event that Executive becomes employed by another for-profit employer which maintains a group health plan or plans for its employees
providing group health coverage or group dental coverage, as applicable; provided, however, any COBRA Coverage shall not be terminated unless and until permitted under COBRA. For purposes of the preceding sentence, (i) the coverage of Executive
(and his dependents, if any) under the health and/or dental plans maintained by the Company shall not terminate until Executive becomes eligible to participate in such group health and group dental coverage of another for-profit employer and
(ii) personal coverage obtained by Executive other than through employment or coverage available by reason of Executive’s performance of services as an independent contractor shall not be considered.

 7. Withholdings; Right of Offset. Parker Drilling may withhold and deduct from any
benefits and payments made or to be made pursuant to this Agreement (a) all federal, state, local and other taxes as may be required pursuant to any law or governmental regulation or ruling, (b) all other normal deductions made with
respect to Parker Drilling’s employees generally, and (c) any advances made to Executive and owed to the Company. 

8. Indemnity Rights. The Parties agree that the terms and provisions of Section 24 of the Employment Agreement shall remain
in full force and effect. 
 9. Life Insurance and Miscellaneous Matters.  

(a) Parker Drilling shall allow Executive to retain the $750,000 Prudential Life Insurance Policy #L8704436 referenced in
Section 5(a)(2) of the Employment Agreement, in order for Executive to continue the life insurance coverage through Executive’s payment of future premiums. Policy premiums have been paid through July 21, 2013. Parker Drilling shall
assign any and all rights in such insurance policy to Executive, and Executive agrees to assume any and all obligations for future payments due under such insurance policy after the Termination Date. 

(b) Executive shall be allowed to retain the iPhone provided by Parker Drilling without cost to Executive, but Executive
shall assume and pay all usage, repair or replacement charges associated with the cellular phone from and after the Termination Date; provided, however, Parker Drilling retains the right to remove any information related to Parker Drilling which
exists on the iPhone from and after the Termination Date. 
 (c) Executive shall also be allowed to retain the
MacBook Pro laptop computer provided by Parker Drilling without cost to Executive; provided, however, Parker Drilling retains the right to remove any information related to Parker Drilling which exists on the laptop from and after the Termination
Date. 
 10. Global Release of Claims. On the Termination Date, Executive shall execute and deliver to Parker Drilling
the Waiver and Release attached hereto as Appendix B (the “Waiver and Release”). 
 11. Restrictive Covenants.
The Parties agree that the terms and provisions of Sections 10 through 20 of the Employment Agreement shall remain in effect after the Effective Date pursuant to their respective terms; provided, however, that the Parties agree that
Executive’s participation in any capacity (whether as proprietor, stockholder, director, partner, employee, agent, independent contractor, consultant, trustee, beneficiary or in any other capacity) with any individual, partnership, firm,
corporation or other business organization or entity that is not one of the entities named on the list attached hereto as Appendix C (or a subsidiary or successor of any such entities) shall not constitute a violation by Executive of the terms and
provisions of Section 13 or Section 14 of the Employment Agreement. 
 12. Knowing and Voluntary Agreement. The
Executive understands it is his choice whether or not to enter into this Agreement and that his decision to do so is voluntary and is made knowingly. The Executive acknowledges that he has been advised by Parker Drilling to seek legal counsel to
review this Agreement. 

  
 Page 4 of 12

 13. Public Disclosure. Parker Drilling and Executive shall cooperate in the
preparation of any public disclosure by Parker Drilling announcing Executive’s scheduled separation from Parker Drilling, the content of which shall be subject to the review and approval of Executive, which approval shall not be unreasonably
withheld, conditioned or delayed. In no event shall Executive’s rights under this Section 13 prevent Parker Drilling from fulfilling its obligations under applicable stock exchange rules and securities laws and regulations. 

14. Dispute Resolution. If any dispute arises out of or is related to this Agreement, Parker Drilling and Executive hereby agree
to resolve such dispute pursuant to the provisions of Section 28 of the Employment Agreement. 
 15. Severability.
It is the desire of the parties hereto that this Agreement (including the provisions of the Employment Agreement incorporated by reference herein) be enforced to the maximum extent permitted by law, and should any provision contained herein be
held unenforceable by a court of competent jurisdiction or arbitrator (pursuant to Section 28 of the Employment Agreement), the parties hereby agree and consent that such provision shall be reformed to create a valid and enforceable provision
to the maximum extent permitted by law; provided, however, if such provision cannot be reformed, it shall be deemed ineffective and deleted herefrom without affecting any other provision of this Agreement. This Agreement should be construed by
limiting and reducing it only to the minimum extent necessary to be enforceable under then applicable law. 
 16. No
Admission of Liability. This Agreement and compliance with this Agreement shall not be construed as an admission by Parker Drilling or Executive of any liability whatsoever, or as an admission by Parker Drilling of any violation of the rights of
Executive or any other person, or any violation of any order, law, statute, duty or contract. 
 17. Intention to Comply with
Code Section 409A. 
 (a) This Agreement is intended to comply with Code Section 409A. Executive
acknowledges that if any provision of this Agreement (or of any award of compensation or benefits) would cause Executive to incur any additional tax or interest under Code Section 409A and accompanying Treasury regulations and other
authoritative guidance, such additional tax and interest shall solely be his responsibility. 
 (b) Pursuant to
Code Section 409A, no reimbursement of any expense shall be made by the Company after December 31st of the year following the calendar year in which the expense was incurred. The amount eligible for reimbursement under this Agreement
during a taxable year may not affect expenses eligible for reimbursement in any other taxable year, and the right to reimbursement under this Agreement is not subject to liquidation or exchange for another benefit. 

(c) For purposes of Code Section 409A, each payment under this Agreement shall be deemed to be a separate payment.
Except as permitted under Code Section 409A, any deferred compensation (within the meaning of Code Section 409A) payable to Executive under this Agreement may not be reduced by, or offset against, any amount owing by Executive to Parker
Drilling or any of its affiliates.

Executive for the attorneys’ fees reasonably incurred by Executive before April 30, 2013 in the negotiation, drafting, execution and implementation of this Agreement and the documents contemplated herein. At Executive’s request, such
payments shall be made directly by Parker Drilling to such attorneys. 
 19. Governing Law. This Agreement will be
interpreted and enforced in accordance with the laws of the State of Texas, without regard to the principles of conflicts of laws. 
 20. Notices. Each notice or other communication required or permitted under this Agreement shall be in writing and transmitted, delivered, or sent by personal delivery, prepaid courier or messenger

or at such other address as the recipient has designated by notice to the other party. Either party may change the address for notice by notifying the other party of such change in accordance with this Section 20.

	2.	I forever waive and relinquish any right or claim to reinstatement to active employment with Company, its affiliates, subsidiaries, divisions, parent, and successors. I
further acknowledge that Company has no obligation to rehire or return me to active duty at any time in the future. 

  

	3.	I acknowledge that all agreements applicable to my employment respecting non-competition, non-solicitation, non-recruitment, derogatory statements, and the confidential

the Separation Agreement and I will not be entitled to the Severance Benefits made under the Separation Agreement until after the seven-day period has elapsed and I have not revoked this Waiver and Release. 

 

	 	d.	I acknowledge that I have received payment for all wages due at time of my employment termination, including any reimbursement for any and all business related

all prior agreements, and that the Company has not made any promise or offered any other agreement, except those expressed in this Waiver and Release and the Separation Agreement, to induce or persuade me to enter into this Waiver and Release.
