provided by Rule 144A under the Securities Act and in offshore transactions in reliance on Regulation S under the Securities Act (“Regulation S”). The Initial Purchasers have advised the Issuers that they will offer and sell the
Notes purchased by them hereunder in accordance with Section 3 hereof as soon as the Initial Purchasers deem advisable. 

In connection with the sale of the Notes, the Issuers have prepared a preliminary offering memorandum, dated November 16, 2011 (the

where specifically noted, in each case the documents incorporated by reference therein. The terms “supplement,” “amendment” and “amend” as used herein with respect

Prior to the time when the sales of the Notes were first made (the “Time of Sale”), the Issuers have prepared and
delivered to the Initial Purchasers a pricing supplement (the “Pricing Supplement”) dated November 16, 2011. The Pricing Supplement together with the Preliminary Memorandum is referred to herein as the “Offering

 Promptly after the Time of Sale and in any event no later than the second Business Day following the
Time of Sale, the Issuers will prepare and deliver to the Initial Purchasers a Final Offering Memorandum (the “Final Memorandum”), which will consist of the Preliminary Memorandum with such changes therein as are required to reflect

gift, promise to give, or authorization of the giving of anything of value to any “foreign official” (as such term is defined in the FCPA) or any foreign political party or official thereof or any candidate for foreign political office, in
contravention of the FCPA; and the Issuers, their subsidiaries and, to the knowledge of the Issuers, their Affiliates have conducted their businesses in compliance with the FCPA and have instituted and maintain policies and procedures designed to

any securities without an appropriate legend) which may result in the loss by the Initial Purchasers of the ability to rely on any stabilization safe harbor provided by the Financial Services Authority under the Financial Services and Markets Act
2000 (the “FSMA”). The Issuers have been informed of the guidance relating to stabilization provided by the Financial Services Authority, in particular in Section MAR 2 Annex 2G of the Financial Services Handbook. 

Each certificate signed by any officer of the Issuers or the Guarantors and delivered to the Initial Purchasers or to counsel for the Initial Purchasers
shall be deemed to be a representation and warranty by the Issuers or the Guarantors, as the case may be, to the Initial Purchasers as to the matters covered thereby.

agent, registrar or depositary, (viii) the cost of the preparation, issuance and delivery of the Notes, (ix) all costs and expenses relating to investor presentations, including any “road show” presentations undertaken in

obligations of the Issuers hereunder for which provision is not otherwise made in this Section. 
 (b) If the sale of the Notes
provided for herein is not consummated because any condition to the obligations of the Initial Purchasers set forth in Section 6 hereof is not satisfied, because this Agreement is terminated pursuant to Section 9 hereof or because of any
failure, refusal or inability on the part of the Issuers to perform all obligations and satisfy all conditions on their part to be performed or satisfied hereunder other than by reason of a default by the Initial Purchasers, the Issuers will
reimburse the Initial Purchasers upon demand for all reasonable out-of-pocket expenses (including counsel fees and disbursements) that shall have been incurred by it in connection with the proposed purchase and sale of the Notes. 

6. Conditions to the Initial Purchaser’s Obligations. The obligations of the Initial Purchasers to purchase and pay for the
Notes shall be subject to the accuracy of the representations and warranties of the Issuers in Section 1 hereof, in each case as of the date hereof and as of the Closing Date, as if made on and as of the Closing Date, to the accuracy of the
statements of the Issuers’ officers made pursuant to the provisions hereof, to the performance by the Issuers of their covenants and agreements hereunder and to the following additional conditions: 

(a) The Initial Purchasers shall have received an opinion, dated the Closing Date, of Ledgewood, P.C., counsel for the
Issuers, in form and substance satisfactory to Wells Fargo, to the effect set forth in Exhibit A hereto. 

  
 24 

 (b) The Initial Purchasers shall have received such other opinions of
counsel, dated the Closing Date, of covering regulatory and local matters as Wells Fargo shall reasonably request. 
 (c) The Initial Purchaser shall have received an opinion, dated the Closing Date, of Cahill Gordon & Reindel llp, Counsel for the Initial Purchasers, with respect to the issuance and sale of the
Notes and such other related matters as Wells Fargo may reasonably require, and the Issuers shall have furnished to such counsel such documents as it may reasonably request for the purpose of enabling it to pass upon such matters. In rendering such
opinion, such counsel may rely as to certain matters of law upon the opinion of Ledgewood referred to in Section 6(a). 
 (d) The Initial Purchasers shall have received on each of the date hereof and the Closing Date a letter, dated the date hereof or the Closing Date, as the case may be, in form and substance satisfactory
to Wells Fargo and Counsel for the Initial Purchasers, from Grant Thornton LLP, independent public accountants, containing statements and information of the type ordinarily included in accountants’ “comfort letters” to underwriters
with respect to the financial statements and certain financial information contained in the Offering Memorandum; provided, however, that the letters referenced in clause (i) shall use a “cut-off date” within three days of the date of
such letter. References to the Offering Memorandum in this paragraph (d) with respect to any letter referred to above shall include any amendment or supplement thereto at the date of any such letter. 

(e) (i) None of the Issuers nor any of their subsidiaries nor any other Guarantor, shall have sustained, since the date of
the latest audited financial statements included or incorporated by reference in the Offering Memorandum (exclusive of any amendment or supplement thereto), any loss or interference with their respective businesses or properties from fire,
explosion, flood, accident or other calamity, whether or not covered by insurance, or from any labor dispute or court or governmental action, order or decree (whether domestic or foreign) otherwise than as set forth in the Offering Memorandum
(exclusive of any amendment or supplement thereto); and (ii) since the respective dates as of which information is given in each Memorandum, there shall not have been any change in the capital stock or long-term debt of any Issuer and its
subsidiaries or any other Guarantor, or any change in or effect on or any development having a prospective change in or effect on the business, operations, properties, assets, liabilities, stockholders’ equity, earnings, condition (financial or
otherwise), results of operations or management of any Issuer and its subsidiaries or any other Guarantor, whether or not in the ordinary course of business, otherwise than as set forth in each such Memorandum (exclusive of any amendment or
supplement thereto), the effect of which, in any such case described in clause (i) or (ii), is, in the sole judgment of Wells Fargo, so material and adverse as to make it impracticable or inadvisable to market the Notes on the terms and in the
manner described in the Offering Memorandum (exclusive of any amendment or supplement thereto). 

  
 25 

 (f) None of the information set forth in the sections of the Offering
Memorandum, or documents incorporated by reference therein, entitled “Use of Proceeds,” “Capitalization,” “Executive Compensation,” “Certain Relationships and Related Transactions” and “Description of
Other Indebtedness” shall have changed, nor shall there have been any change in the information with respect to the directors and officers of the Issuers, if the effect of any such change, individually or in the aggregate, in the sole judgment
of Wells Fargo make it impracticable or inadvisable to proceed with the offering or the delivery of the Notes on the terms and in the manner described in the Offering Memorandum, exclusive of any amendment or supplement thereto. 

(g) The Initial Purchasers shall have received a certificate, dated the Closing Date and in form and substance
satisfactory to Wells Fargo, of the Chairman of the Managing Board, the President or a Vice President and the Chief Financial Officer of the General Partner as to the accuracy of the representations and warranties of the Issuers in this Agreement at

in this Agreement at and as of the Closing Date; that the Finance Co has performed all covenants and agreements and satisfied all conditions on their part to be performed or satisfied at or prior to the Closing Date; and as to the matters set forth
in Sections 6(e), (f) and (j) hereof. 
 (i) The Initial Purchasers shall have received a certificate,
dated the Closing Date and in form and substance satisfactory to Wells Fargo, of the Chairman of the Board, the President or a Vice President and the Chief Financial Officer of each Guarantor, or the General Partner of such Guarantor, as the case
may be, as to the accuracy of the representations and warranties of such Guarantor in this Agreement at and as of the Closing Date; that such Guarantor has performed all covenants and agreements and satisfied all conditions on their part to be
performed or satisfied at or prior to the Closing Date; and as to the matters set forth in Section 6(e) hereof. 
 (j) Subsequent to the date hereof, there shall not have been any decrease in the rating of the Notes or any of the Partnership’s other debt securities by any “nationally recognized statistical
rating agency,” as that term is defined by the Commission for purposes of Rule 436(g)(2) under the Securities Act, and no such organization shall have publicly announced that it has under surveillance or review its ratings of the Securities or
any of the Partnership’s other debt securities or any notice or public announcement given of any intended or potential decrease in any such rating or that any such securities rating agency has under surveillance or review, with possible
negative implications, its rating of the Notes. 

  
 26 

 (k) The Notes shall be eligible for clearance and settlement through the
Depository Trust Company. 
 (l) On or before the Closing Date, the Initial Purchasers and Counsel for the

 7. Indemnification and Contribution. (a) Each Issuer and each Guarantor, jointly and severally, agrees to indemnify and hold harmless each Initial Purchasers, their affiliates, directors and
officers and each person, if any, who controls (within the meaning of Section 15 of the Securities Act or Section 20 of the Exchange Act) such Initial Purchaser against any losses, claims, damages or liabilities, joint or several, to which
such Initial Purchaser or such other person may become subject, insofar as such losses, claims, damages or liabilities (or actions in respect thereof) arise out of or are based upon (i) any untrue statement or alleged untrue statement of any
material fact contained in the Preliminary Memorandum, the Offering Memorandum or any amendment or supplement thereto or any electronic road show; or (ii) the omission or alleged omission to state in the Preliminary Memorandum, the Offering
Memorandum, the Final Memorandum or any amendment or supplement thereto and any electronic road show a material fact necessary to make the statements therein, in the light of the circumstances in which they were made, not misleading, and will
reimburse, as incurred, such Initial Purchaser and each such other person for any legal or other expenses reasonably incurred by such Initial Purchaser or such other person in connection with investigating, defending against or appearing as a
third-party witness in connection with any such loss, claim, damage, liability or action; provided, however, that the Issuers and the Guarantors will not be liable in any such case to the extent that any such loss, claim, damage or
liability arises out of or is based upon any untrue statement or alleged untrue statement or omission or alleged omission made in any Preliminary Memorandum, the Offering Memorandum or any amendment or supplement thereto or any electronic road show,
in reliance upon and in conformity with written information relating to such Initial Purchaser furnished to the Issuers by such Initial Purchaser through Wells Fargo specifically for use therein as set forth in Section 10 hereof. 

(b) The Initial Purchasers will, severally and not jointly, indemnify and hold harmless the Issuers and the Guarantors and their
respective affiliates, directors, officers, and each person, if any, who controls any of the Issuers or the Guarantors within the meaning of Section 15 of the Securities Act or Section 20 of the Exchange Act against any losses, claims,
damages or liabilities to which the Issuers, the Guarantors, any such affiliates, directors or officers or such controlling person may become subject, insofar as such losses, claims, damages or liabilities (or actions in respect thereof) arise out
of or are based upon (i) any untrue statement or alleged untrue statement of any material fact contained in the Preliminary Memorandum or any amendment or supplement thereto or any electronic road show, or (ii) the omission or alleged
omission to state in the Preliminary Memorandum, or the Offering Memorandum or any amendment or supplement thereto or any electronic road show a material fact necessary to make the 

  
 27 

 
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 reliance upon and in conformity with written information furnished to the Issuers by the Initial Purchaser specifically for use therein as set forth in Section 10 hereof and, subject to the
limitation set forth immediately preceding this clause, will reimburse as incurred, any legal or other expenses reasonably incurred by the Issuers or the Guarantors or any such affiliates, directors or officers or such controlling person in
connection with investigating, defending against or appearing as a third-party witness in connection with, any such loss, claim, damage, liability or action in respect thereof. 

(c) Promptly after receipt by any person to whom indemnity may be available under this Section 7 (the “indemnified
party”) of notice of the commencement of any action, such indemnified party will, if a claim in respect thereof is to be made against any person from whom indemnity may be sought under this Section 7 (the “indemnifying
party”), notify such indemnifying party of the commencement thereof; provided, however, that the failure to notify the indemnifying party shall not relieve it from any liability which it may have under this Section 7 except to the
extent it has been materially prejudiced by such failure and, provided further, that the failure to notify the indemnifying party shall not relieve it from any liability which it may have to an indemnified party otherwise than under this
Section 7. In case any such action is brought against any indemnified party, and such indemnified party notifies the relevant indemnifying party of the commencement thereof, such indemnifying party will be entitled to participate therein and,
to the extent that it may wish, to assume the defense thereof, jointly with any other indemnifying party similarly notified, with counsel satisfactory to such indemnified party; provided, however, that if the named parties in any such action
(including impleaded parties) include both the indemnified party and the indemnifying party and the indemnified party shall have concluded, based on advice of outside counsel, that there may be one or more legal defenses available to it and/or other
indemnified parties which are different from or additional to those available to the indemnifying party or that representation of both parties by the same counsel would be inappropriate due to actual or potential differing interests between them,
the indemnifying party shall not have the right to direct the defense of such action on behalf of such indemnified party or parties and such indemnified party or parties shall have the right to select separate counsel to defend such action on behalf
of such indemnified party or parties. After notice from an indemnifying party to an indemnified party of its election so to assume the defense thereof and approval by such indemnified party of counsel appointed to defend such action, such
indemnifying party will not be liable to such indemnified party under this Section 7 for any legal or other expenses, other than reasonable costs of investigation, subsequently incurred by such indemnified party in connection with the defense
thereof, unless (i) such indemnified party shall have employed separate counsel in accordance with the proviso to the immediately preceding sentence or (ii) such indemnifying party does not promptly retain counsel satisfactory to such
indemnified party or (iii) such indemnifying party has authorized the employment of counsel for such indemnified party at the expense of the indemnifying party. After such notice from an indemnifying party to an indemnified party, such
indemnifying party will not be liable for the costs and expenses of any settlement of such action effected by such indemnified party without the written consent of such indemnifying party. Notwithstanding the foregoing sentence, if at any

  
 28 

 
time an indemnified party shall have requested an indemnifying party to reimburse the indemnified party for fees and expenses of counsel as contemplated by (i), (ii) or (iii) of the
third sentence of this paragraph, the indemnifying party agrees that it shall be liable for any settlement of any proceeding effected without its written consent if (x) such settlement is entered into more than 30 days after receipt by such
indemnifying party of the aforesaid request and (y) such indemnifying party shall not have reimbursed the indemnified party in accordance with such request prior to the date of such settlement. An indemnifying party will not, without the prior
written consent of the indemnified party, settle or compromise or consent to the entry of any judgment in any pending or threatened claim, action, suit or proceeding in respect of which indemnification may be sought hereunder (whether or not the
indemnified party or any other person that may be entitled to indemnification hereunder is a party to such claim, action, suit or proceeding) unless such settlement, compromise or consent includes an unconditional release of the indemnified party
and such other persons from all liability arising out of such claim, action, suit or proceeding. 
 (d) (i) In circumstances in
which the indemnity agreement provided for in the preceding paragraphs of this Section 7 is unavailable or insufficient, for any reason, to hold harmless an indemnified party in respect of any losses, claims, damages or liabilities (including,
without limitation, any legal or other expenses incurred in connection with defending or investigating any action or claim) (or actions in respect thereof) (“Losses”), the Issuers and the Guarantors, on the one hand, and the Initial
Purchasers, on the other, in order to provide for just and equitable contribution, agree to contribute to the amount paid or payable by such indemnified party as a result of such Losses to which the Issuers and the Guarantors, on the one hand, and
the Initial Purchasers, on the other, may be subject, 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, from the offering of
the Notes or (ii) if the allocation provided by the foregoing clause (i) is unavailable for any reason, not only such relative benefits but also the relative fault of the Issuers and the Guarantors, on the one hand, and the Initial
Purchasers, on the other, in connection with the statements or omissions or alleged statements or omissions that resulted in such Losses. The relative benefits received by the Issuers and the Guarantors, on the one hand, and the Initial Purchasers,
on the other, shall be deemed to be in the same proportion as the total proceeds from the offering (before deducting expenses) received by the Issuers bear to the total discounts and commissions received by the Initial Purchasers from the Issuers in
connection with the purchase of the Notes hereunder as set forth in the Offering Memorandum. The relative fault of the parties shall be determined by reference to, among other things, whether the untrue or alleged untrue statement of a material fact
or the omission or alleged omission to state a material fact relates to information supplied by the Issuers, the Guarantors or the Initial Purchasers, the parties’ intent, relative knowledge, access to information and opportunity to correct or
prevent such statement or omission, and any other equitable considerations appropriate in the circumstances. The Issuers, the Guarantors and the Initial Purchasers agree that it would not be just and equitable if contribution were determined by pro
rata allocation or by any other method of allocation that does not take into account the equitable considerations referred to above. Notwithstanding any other provision of this paragraph (d), the Initial Purchasers shall not be obligated to make
contributions hereunder that in the aggregate exceed the total underwriting discounts and 

  
 29 

 
commissions received by the Initial Purchasers from the Issuers in connection with the purchase of the Notes hereunder, and no person guilty of fraudulent misrepresentation (within the meaning of
Section 11(f) of the Securities Act) shall be entitled to contribution from any person who was not guilty of such fraudulent misrepresentation. For purposes of this paragraph (d), each person, if any, who controls an Initial Purchaser within
the meaning of Section 15 of the Securities Act or Section 20 of the Exchange Act and each other person listed in Section 7(a) hereof shall have the same rights to contribution as an Initial Purchaser, and each affiliate, director or
officer of the Issuers or any Guarantor and each person, if any, who controls the Issuers within the meaning of Section 15 of the Securities Act or Section 20 of the Exchange Act, shall have the same rights to contribution as the Issuers
and the Guarantors. The Initial Purchasers’ obligations to contribute pursuant to this Section 7(d) are several and not joint. 
 (e) The obligations of the Issuers and the Guarantors under this Section 7 shall be in addition to any obligations or liabilities which the Issuers and the Guarantors may otherwise have and the
obligations of the Initial Purchasers under this Section 7 shall be in addition to any obligations or liabilities which the Initial Purchasers may otherwise have. 
 8. Survival. The respective representations, warranties, agreements, covenants, indemnities and other statements of the Issuers, the Guarantors, their respective officers, and the Initial
Purchasers set forth in this Agreement or made by or on behalf of them, respectively, pursuant to this Agreement shall remain in full force and effect, regardless of (i) any investigation made by or on behalf of the Issuers, the Guarantors,
their respective officers or directors or any controlling person referred to in Section 7 hereof or the Initial Purchasers and (ii) delivery of and payment for the Notes. The respective agreements, covenants, indemnities and other
statements set forth in Sections 5, 7 and Sections 10-15 hereof shall remain in full force and effect, regardless of any termination or cancellation of this Agreement. 
 9. Termination. (a) The Initial Purchasers may terminate this Agreement with respect to the Notes by notice to the Issuers at any time on or prior to the Closing Date in the event that the
Issuers shall have failed, refused or been unable to perform in any material respect all obligations and satisfy in any material respect all conditions on their part to be performed or satisfied hereunder at or prior thereto or if, at or prior to
the Closing Date (i) trading in securities generally on the New York Stock Exchange, the NASDAQ National Market or in the over-the-counter market, or trading in any securities of the Issuers on any exchange or in the over-the-counter market,
shall have been suspended or minimum or maximum prices shall have been established on any such exchange or market; (ii) there has been a material disruption in commercial banking or securities settlement, payment or clearance services in the
United States; (iii) a banking moratorium shall have been declared by New York, North Carolina or United States authorities or (iv) there shall have been (A) an outbreak or escalation of hostilities between the United States and any
foreign power, (B) an outbreak or escalation of any other insurrection or armed conflict involving the United States, (C) the occurrence of any other calamity or crisis involving the United States or (D) any change in general
economic, political or financial conditions which has an effect on the U.S. financial markets that, in the case of any event described in this clause (iv), in the sole judgment of Wells Fargo, makes it impracticable or inadvisable to proceed with
the offer, sale and delivery of the Notes as disclosed in the Preliminary Memorandum or the Offering Memorandum, exclusive of any amendment or supplement thereto. 

  
 30 

 (b) Termination of this Agreement pursuant to this Section 9 shall be without liability
of any party to any other party except as provided in Sections 5 and 7 hereof. 
 10. Information Supplied by Initial
Purchasers. The statements set forth in the second and fourth sentences of the third paragraph, the second sentence of the fifth paragraph and the seventh, eighth and ninth paragraphs under the heading “Plan of Distribution” in the
Preliminary Memorandum and the Offering Memorandum, to the extent such statements relate to the Initial Purchasers, constitute the only information furnished by the Initial Purchasers to the Issuers for the purposes of Sections 1(a) and 7 hereof.

 11. Notices. All communications hereunder shall be in writing and, if sent to any of the Initial Purchasers, shall be
delivered or sent by mail or facsimile transmission and confirmed in writing to Wells Fargo Securities, One Wells Fargo Center, 301 South College Street, Charlotte, North Carolina 28288-0604, Attention: Transaction Management Department, with a copy
to Cahill Gordon & Reindel llp, 80 Pine Street, New York, New York 10005, Attention: Noah B. Newitz, and if sent to the Issuers, shall be delivered or sent by mail, telex or facsimile transmission and confirmed in writing to the Issuers at
Atlas Pipeline Partners, L.P., Westpointe Corporate Center One, 1550 Coraopolis Heights, Moon Township, Pennsylvania 15108, Attention: Trey Karlovich, with a copy to Ledgewood, 1900 Market Street, Suite 750, Philadelphia, Pennsylvania 19103,
Attention: Lisa A Ernst. 
 12. Successors. This Agreement shall inure to the benefit of and shall be binding upon the
Initial Purchasers, the Issuers and the Guarantors and their respective successors and legal representatives, and nothing expressed or mentioned in this Agreement is intended or shall be construed to give any other person any legal or equitable
right, remedy or claim under or in respect of this Agreement, or any provisions herein contained, this Agreement and all conditions and provisions hereof being intended to be and being for the sole and exclusive benefit of the Initial Purchasers,
the Issuers and the Guarantors and their respective successors and legal representatives, and for the benefit of no other person, except that (i) the indemnities of the Issuers contained in Section 7 of this Agreement shall also be for the
benefit of any person or persons who control an Initial Purchaser within the meaning of Section 15 of the Securities Act or Section 20 of the Exchange Act and (ii) the indemnities of the Initial Purchasers contained in Section 7
of this Agreement shall also be for the benefit of the affiliates, directors and officers of the Issuers and the Guarantors, and any person or persons who control the Issuers or the Guarantors within the meaning of Section 15 of the Securities
Act or Section 20 of the Exchange Act. No purchaser of Notes from an Initial Purchasers shall be deemed a successor to such Initial Purchaser because of such purchase. 
 13. Applicable Law. This Agreement shall be governed by the laws of the State of New York. 

  
 31 

 14. Submission to Jurisdiction and Service of Process; Waiver of Jury Trial.
(a) Any claim, counterclaim or dispute of any kind or nature whatsoever arising out of or in any way relating to this Agreement (“Claim”), directly or indirectly, may be commenced, prosecuted or continued in any court of the
State of New York located in the City and County of New York or in the United States District Court for the Southern District of New York, which courts shall have non-exclusive jurisdiction over the adjudication of such matters, and each Issuer,
each Initial Purchaser and each of the Subsidiaries and Guarantors consents to the non-exclusive jurisdiction of such courts and personal service with respect thereto. 
 (b) Each party agrees that any service of process or other legal summons in connection with any Proceeding may be served on it by mailing a copy thereof by registered mail, or a form of mail substantially
equivalent thereto, postage prepaid, addressed to the served party at its address as provided for in Section 11 hereof. Nothing in this Section shall affect the right of the parties to serve process in any other manner permitted by law.

 (c) Each Issuer (on its behalf and, to the extent permitted by applicable law, on behalf of its stockholders, partners and
affiliates), each Initial Purchaser and each of the Subsidiaries and Guarantors waives all right to trial by jury in any action, proceeding or counterclaim (whether based upon contract, tort or otherwise) in any way arising out of or relating to
this Agreement. Each Issuer and each of the Subsidiaries and Guarantors agree that a final judgment in any such proceeding brought in any such court shall be conclusive and binding upon it and may be enforced in any other courts in the jurisdiction
of which it is or may be subject, by suit upon such judgment. 
 15. Defaulting Initial Purchasers. If, on the Closing
Date, any Initial Purchaser defaults in the performance of its obligations under this Agreement, the non-defaulting Initial Purchasers shall be obligated to purchase the Notes that such defaulting Initial Purchaser or Initial Purchasers agreed but
failed to purchase on the Closing Date (the “Remaining Notes”) in the respective proportions that the principal amount of the Notes set opposite the name of each non-defaulting Initial Purchaser in Schedule I hereto bears to the
total number of the Notes set opposite the names of all the non-defaulting Initial Purchasers in Schedule I hereto; provided, however, that the non-defaulting Initial Purchasers shall not be obligated to purchase any of the Notes on
the Closing Date if the total amount of Notes which the defaulting Initial Purchaser or Initial Purchasers agreed but failed to purchase on such date exceeds 10% of the total amount of Notes to be purchased on the Closing Date. If the foregoing
maximum is exceeded, the non-defaulting Initial Purchasers, or those other purchasers satisfactory to the Initial Purchasers who so agree, shall have the right, but not the obligation, to purchase, in such proportion as may be agreed upon among
them, all the Remaining Notes. If the non-defaulting Initial Purchasers or other Initial Purchasers satisfactory to the Initial Purchasers do not elect to purchase the Remaining Notes, this Agreement shall terminate without liability on the part of
any non-defaulting Initial Purchaser or the Issuers, except that the Issuers will continue to be liable for the payment of expenses to the extent set forth herein. 
 Nothing contained in this Agreement shall relieve a defaulting Initial Purchaser of any liability it may have to the Issuers for damages caused by its default. If other purchasers

  
 32 

 
are obligated or agree to purchase the Notes of a defaulting or withdrawing Initial Purchaser, the Issuers or Wells Fargo may postpone the Closing Date for up to five full business days in order
to effect any changes in the Transaction Documents or in any other document or arrangement that, in the opinion of counsel for the Issuers or Counsel for the Initial Purchasers, may be necessary. 

16. Counterparts. This Agreement may be executed in two or more counterparts, each of which shall be deemed an original, but all
of which together shall constitute one and the same instrument.

 EXHIBIT A-1 
 FORM OF OPINION OF LEDGEWOOD LAW FIRM 
 The opinion of Ledgewood, P.C. to be
delivered pursuant to Section 6(a) of the Purchase Agreement shall be to the effect that:

In our capacity as counsel to the Issuers, we have examined a copy of the Offering Memorandum (including the documents
incorporated by reference therein). We have also reviewed and participated in discussions concerning the preparation of the Preliminary Memorandum and the Offering Memorandum with certain officers and employees of the Partnership, with its auditors
and with representatives of and counsel to the Initial Purchasers. The limitations inherent in the independent verification of factual matters and in the role of outside counsel are such, however, that we cannot and do not assume any responsibility
for the accuracy, completeness or fairness of any of the statements made in the Offering Memorandum, except as set forth in paragraphs L and M of our opinion addressed to you, dated the date hereof. 

Subject to the limitations set forth in the immediately preceding paragraph, we advise you that, on the basis of the
information we gained in the course of performing the services referred to above, no facts came to our attention which give us reason to believe that the Offering Memorandum (including the documents incorporated by reference therein) (other than the
financial statements and schedules and other financial data included therein or omitted therefrom, as to which we have not been requested to express a view) as of the Time of Sale and as of the date hereof and the Final Memorandum (other than the
financial statements and schedules and other financial data included therein or omitted therefrom, as to which we have not been requested to express a view), as of its date or the date hereof, contained or contains an untrue statement of a material
fact or omitted or omits to state a material fact necessary in order to make the statements therein, in the light of the circumstances under which they were made, not misleading.

 (b) In the event that (i) the

law or applicable interpretations of the Staff of the SEC, (ii) the Exchange Offer is 

  
 6 

 
not for any other reason completed within 360 calendar days following the Closing Date, (iii) upon receipt of a written request from any Initial Purchaser representing that it holds
Registrable Securities that are or were ineligible to be exchanged in the Exchange Offer or (iv) in the case of any Holder that participates in the Exchange Offer, such Holder does not receive Exchange Securities on the date of the exchange
that may be sold without restriction under state and federal securities laws (other than due solely to the status of such Holder as an affiliate of either Issuer within the meaning of the Securities Act) and so notifies (such notification or written
request pursuant to the preceding clause (iii), a “Shelf Request”) the Issuers within 30 days after such Holder first becomes aware of such restrictions, the Issuers and the Guarantors shall use their reasonable best efforts to
cause to be filed as soon as practicable after such determination, date or Shelf Request, as the case may be, a Shelf Registration Statement providing for the sale of all the Registrable Securities by the Holders thereof and to have such Shelf
Registration Statement become effective. 
 In the event that the Issuers and the Guarantors are required to file a Shelf
Registration Statement pursuant to clauses (iii) or (iv) of the preceding sentence, the Issuers and the Guarantors shall use their reasonable best efforts to file and become effective both an Exchange Offer Registration Statement pursuant
to Section 2(a) with respect to all Registrable Securities and a Shelf Registration Statement (which may be a combined Registration Statement with the Exchange Offer Registration Statement) with respect to offers and sales of Registrable
Securities held by the Initial Purchasers or such Holder after completion of the Exchange Offer. 
 The Issuers and the
Guarantors agree to use their reasonable best efforts (i) to file the Shelf Registration Statement as promptly as practicable but in any event by the 30th day after they become obligated to make the filing, (ii) to cause the registration
statement to become effective within 60 days after such filing and (iii) to keep the Shelf Registration Statement continuously effective until the second anniversary of the Closing Date or such shorter period that will terminate when all the
Registrable Securities covered by the Shelf Registration Statement have been sold pursuant to the Shelf Registration Statement (the “Shelf Effectiveness Period”). The Issuers and the Guarantors further agree to supplement or amend
the Shelf Registration Statement and the related Prospectus if required by the rules, regulations or instructions applicable to the registration form used by the Issuers for such Shelf Registration Statement or by the Securities Act or by any other
rules and regulations thereunder or if reasonably requested by a Holder of Registrable Securities with respect to information relating to such Holder, and to use their reasonable best efforts to cause any such amendment to become effective and such
Shelf Registration Statement and Prospectus to become usable as soon as thereafter practicable. The Issuers and the Guarantors agree to furnish to the Holders of Registrable Securities copies of any such supplement or amendment promptly after its
being used or filed with the SEC. 

  
 7 

 (c) The Issuers and the Guarantors shall pay all Registration Expenses in connection with
any registration pursuant to Section 2(a) or Section 2(b) hereof. Each Holder shall pay all underwriting discounts and commissions, brokerage commissions and transfer taxes, if any, relating to the sale or disposition of such Holder’s
Registrable Securities pursuant to the Shelf Registration Statement. 
 (d) An Exchange Offer Registration Statement pursuant to
Section 2(a) hereof or a Shelf Registration Statement pursuant to Section 2(b) hereof will not be deemed to have become effective unless it has been declared effective by the SEC. 

In the event that either the Exchange Offer is not completed or the Shelf Registration Statement, if required pursuant to
Section 2(b)(i) or 2(b)(ii) hereof, does not become effective on or prior to the 360th calendar day after the Closing Date (the “Target Registration Date”), the interest rate on the Securities will be increased by
(i) 0.25% per annum for the first 90 day period immediately following the Target Registration Date and (ii) an additional 0.25% per annum with respect to each subsequent 90 day period, in each case until the Exchange Offer is
completed or the Shelf Registration Statement, if required hereby, becomes effective up to a maximum increase of 1.00% per annum. In the event that the Company receives a Shelf Request pursuant to Section 2(b)(iii), and the Shelf
Registration Statement required to be filed thereby does not become effective by the later of (x) the 360th calendar day after the Closing Date or (y) 90 days after the obligation to file such Shelf Registration arises pursuant to
Section 2(b) (such later date, the “Shelf Additional Interest Date”), then the interest rate on the Securities will be increased by 0.25% per annum for the first 90 day period payable commencing from one day after the Shelf
Additional Interest Date and (ii) an additional 0.25% per annum with respect to each subsequent 90 day period, in each case until the Shelf Registration Statement becomes effective up to a maximum increase of 1.00% per annum.

 If the Shelf Registration Statement, if required hereby, has become effective and thereafter either ceases to be effective or
the Prospectus contained therein ceases to be usable, in each case whether or not permitted by this Agreement, at any time during the Shelf Effectiveness Period, and such failure to remain effective or usable exists for more than 30 days (whether or
not consecutive) in any 12-month period, then the interest rate on the Securities will be increased by (i) 0.25% per annum for the first 90 day period commencing on the 31st day in such 12-month period and (ii) an additional
0.25% per annum with respect to each subsequent 90 day period up to a maximum of 1.00% per annum and ending on such date that the Shelf Registration Statement has again become effective or the Prospectus again becomes usable. 

(e) Without limiting the remedies available to the Initial Purchasers and the Holders, the Issuers acknowledge that any failure by the
Issuers to comply with their obligations under Section 2(a) and Section 2(b) hereof may result in material irreparable injury to the Initial Purchasers or the Holders for which there is no adequate remedy at law, that it will

  
 8 

 
not be possible to measure damages for such injuries precisely and that, in the event of any such failure, the Initial Purchasers or any Holder may obtain such relief as may be required to
specifically enforce the Issuers’ and the Guarantors’ obligations under Section 2(a) and Section 2(b) hereof. 
 3. Registration Procedures. In connection with their obligations pursuant to Section 2(a) and Section 2(b) hereof, the Issuers and the Guarantors shall as expeditiously as possible

 (a) prepare and file with the SEC a Registration Statement on the appropriate form under the Securities Act,
which form (x) shall be selected by the Issuers and the Guarantors, (y) shall, in the case of a Shelf Registration, be available for the sale of the Registrable Securities by the Holders thereof and (z) shall comply as to form in all
material respects with the requirements of the applicable form and include all financial statements required by the SEC to be filed therewith; and use their reasonable best efforts to cause such Registration Statement to become effective and remain
effective for the applicable period in accordance with Section 2 hereof; 
 (b) prepare and file with the
SEC such amendments and post-effective amendments to each Registration Statement as may be necessary to keep such Registration Statement effective for the applicable period in accordance with Section 2 hereof and cause each Prospectus to be
supplemented by any required prospectus supplement and, as so supplemented, to be filed pursuant to Rule 424 under the Securities Act; and keep each Prospectus current during the period described in Section 4(3) of and Rule 174 under the
Securities Act that is applicable to transactions by brokers or dealers with respect to the Registrable Securities or Exchange Securities; 
 (c) in the case of a Shelf Registration, furnish to each Holder of Registrable Securities, to counsel for the Initial Purchasers, to counsel for such Holders and to each Underwriter of an Underwritten
Offering of Registrable Securities, if any, without charge, as many copies of each Prospectus, including each preliminary prospectus, and any amendment or supplement thereto, in order to facilitate the sale or other disposition of the Registrable
Securities thereunder; and the Issuers consent to the use of such Prospectus and any amendment or supplement thereto in accordance with applicable law by each of the Holders of Registrable Securities and any such Underwriters in connection with the
offering and sale of the Registrable Securities covered by and in the manner described in such Prospectus, preliminary prospectus or any amendment or supplement thereto in accordance with applicable law; 

(d) use their reasonable best efforts to register or qualify the Registrable Securities under all applicable state
securities or blue sky laws of such jurisdictions as any Holder of Registrable Securities covered by a Registration Statement shall reasonably request in writing by the time the applicable Registration Statement is declared

  
 9 

 
effective by the SEC; cooperate with the Holders in connection with any filings required to be made with the Financial Industry Regulatory Authority; and do any and all other acts and things that
may be reasonably necessary or advisable to enable each Holder to complete the disposition in each such jurisdiction of the Registrable Securities owned by such Holder; provided that neither Issuer shall be required to (i) qualify as a foreign
corporation or other entity or as a dealer in securities in any such jurisdiction where it would not otherwise be required to so qualify, (ii) file any general consent to service of process in any such jurisdiction or (iii) subject itself
to taxation in any such jurisdiction if it is not so subject; 
 (e) in the case of a Shelf Registration, notify
each Holder of Registrable Securities, counsel for such Holders and counsel for the Initial Purchaser promptly and, if requested by any such Holder or counsel, confirm such advice in writing (i) when a Registration Statement has become
effective and when any post-effective amendment thereto has been filed and becomes effective, (ii) of any request by the SEC or any state securities authority for amendments and supplements to a Registration Statement and Prospectus or for
additional information after the Registration Statement has become effective, (iii) of the issuance by the SEC or any state securities authority of any stop order suspending the effectiveness of a Registration Statement or the initiation of any
proceedings for that purpose, including the receipt by the Issuers of any notice of objection of the SEC to the use of a Shelf Registration Statement or any post-effective amendment thereto pursuant to Rule 401(g)(2) under the Securities Act,
(4) if, between the applicable effective date of a Shelf Registration Statement and the closing of any sale of Registrable Securities covered thereby, the representations and warranties of any Issuer or Guarantor contained in any underwriting
agreement, securities sales agreement or other similar agreement, if any, relating to an offering of such Registrable Securities cease to be true and correct in all material respects or if any Issuer or any Guarantor receives any notification with
respect to the suspension of the qualification of the Registrable Securities for sale in any jurisdiction or the initiation of any proceeding for such purpose, (v) of the happening of any event during the period a Shelf Registration Statement
is effective that makes any statement made in such Registration Statement or the related Prospectus untrue in any material respect or that requires the making of any changes in such Registration Statement or Prospectus in order to make the
statements therein not misleading and (vi) of any determination by any Issuer that a post-effective amendment to a Registration Statement or any amendment or supplement to the Prospectus would be appropriate; 

(f) use their reasonable best efforts to obtain the withdrawal of any order suspending the effectiveness of a Registration
Statement or, in the case of a Shelf Registration, the resolution of any objection of the SEC pursuant to Rule 401(g)(2), including by filing an amendment to such Shelf Registration Statement on the proper form, at the earliest possible moment and
provide immediate notice to each Holder of the withdrawal of any such order or such resolution; 

  
 10 

 (g) in the case of a Shelf Registration, furnish to each Holder of
Registrable Securities, without charge, at least one conformed copy of each Registration Statement and any post-effective amendment thereto (without any documents incorporated therein by reference or exhibits thereto, unless requested); 

(h) in the case of a Shelf Registration, cooperate with the selling Holders of Registrable Securities to facilitate the
timely preparation and delivery of certificates representing Registrable Securities to be sold and not bearing any restrictive legends and enable such Registrable Securities to be issued in such denominations and registered in such names (consistent
with the provisions of the Indenture) as the selling Holders may reasonably request at least one Business Day prior to the closing of any sale of Registrable Securities; 

(i) in the case of a Shelf Registration, upon the occurrence of any event contemplated by Section 3(e)(v) hereof, use
their reasonable best efforts to prepare and file with the SEC a supplement or post-effective amendment to such Shelf Registration Statement or the related Prospectus or any document incorporated therein by reference or file any other required
document so that, as thereafter delivered to purchasers of the Registrable Securities, such Prospectus will not contain any untrue statement of a material fact or omit to state a material fact necessary to make the statements therein, in the light
of the circumstances under which they were made, not misleading; and the Issuers and the Guarantors shall notify the Holders of Registrable Securities to suspend use of the Prospectus as promptly as practicable after the occurrence of such an event,
and such Holders hereby agree to suspend use of the Prospectus until the Issuers and the Guarantors have amended or supplemented the Prospectus to correct such misstatement or omission; 

(j) a reasonable time prior to the filing of any Registration Statement, any Prospectus, any amendment to a Registration
Statement or amendment or supplement to a Prospectus or of any document that is to be incorporated by reference into a Registration Statement or a Prospectus after initial filing of a Registration Statement, provide copies of such document to the
Initial Purchasers and their counsel (and, in the case of a Shelf Registration Statement, to the Holders of Registrable Securities and their counsel) and make such of the representatives of the Issuers and the Guarantors as shall be reasonably
requested by the Initial Purchasers and their counsel (and, in the case of a Shelf Registration Statement, the Holders of Registrable Securities or their counsel) available for discussion of such document; and the Issuers and the Guarantors shall
not, at any time after initial filing of a Registration Statement, use or file any Prospectus, any amendment of or supplement to a Registration Statement or a Prospectus, or any document that is to be incorporated by reference into a Registration

  
 11 

 
Statement or a Prospectus, of which the Initial Purchasers and their counsel (and, in the case of a Shelf Registration Statement, the Holders of Registrable Securities and their counsel) shall
not have previously been advised and furnished a copy or to which the Initial Purchasers or their counsel (and, in the case of a Shelf Registration Statement, the Holders of Registrable Securities or their counsel) shall object; 

(k) obtain a CUSIP number for all Exchange Securities or Registrable Securities, as the case may be, not later than the
effective date of a Registration Statement, which shall be the same CUSIP number as the notes issued under the Indenture on June 27, 2008, unless it is not possible to obtain the same number following the best efforts of the Partnership to do
so; 
 (l) [Reserved]; 
 (m) in the case of a Shelf Registration, make available for inspection by a representative of the Holders of the Registrable Securities (an “Inspector”), any Underwriter participating in
any disposition pursuant to such Shelf Registration Statement, and attorneys and accountants designated by the Holders, at reasonable times and in a reasonable manner, all pertinent financial and other records, documents and properties of the
Issuers and the Guarantors, and cause the respective officers, directors and employees of the Issuers and the Guarantors to supply all information reasonably requested by any such Inspector, Underwriter, attorney or accountant in connection with a
Shelf Registration Statement; provided that if any such information is identified by the Issuers as being confidential or proprietary, each Person receiving such information shall take such actions as are reasonably necessary to protect the
confidentiality of such information to the extent such action is otherwise not inconsistent with, an impairment of or in derogation of the rights and interests of any Inspector, Holder or Underwriter); 

(n) in the case of a Shelf Registration, use their reasonable best efforts to cause all Registrable Securities to be
listed on any securities exchange or any automated quotation system on which similar securities issued or guaranteed by any Issuer or any Guarantor are then listed if requested by the Majority Holders, to the extent such Registrable Securities
satisfy applicable listing requirements; 
 (o) if reasonably requested by any Holder of Registrable Securities
covered by a Registration Statement, promptly incorporate in a Prospectus supplement or post-effective amendment such information with respect to such Holder as such Holder reasonably requests to be included therein and make all required filings of
such Prospectus supplement or such post-effective amendment as soon as the Issuers have received notification of the matters to be incorporated in such filing; 

  
 12 

 (p) in the case of a Shelf Registration, enter into such customary
agreements and take all such other actions in connection therewith (including those requested by the Holders of a majority in principal amount of the Registrable Securities being sold) in order to expedite or facilitate the disposition of such
Registrable Securities including, but not limited to, an Underwritten Offering and in such connection, (i) to the extent possible, make such representations and warranties to the Holders and any Underwriters of such Registrable Securities with
respect to the business of the Partnership and its subsidiaries, the Registration Statement, Prospectus and documents incorporated by reference or deemed incorporated by reference, if any, in each case, in form, substance and scope as are
customarily made by issuers to underwriters in underwritten offerings and confirm the same if and when requested, (ii) obtain opinions of counsel to the Issuers (which counsel and opinions, in form, scope and substance, shall be reasonably
satisfactory to the Holders and such Underwriters and their respective counsel) addressed to each selling Holder and Underwriter of Registrable Securities, covering the matters customarily covered in opinions requested in underwritten offerings,
(iii) obtain “comfort” letters from the independent certified public accountants of the Issuers (and, if necessary, any other certified public accountant of any subsidiary of the Issuers or any Guarantor, or of any business acquired
by the Issuers or any Guarantor for which financial statements and financial data are or are required to be included in the Registration Statement) addressed to each selling Holder and Underwriter of Registrable Securities, such letters to be in
customary form and covering matters of the type customarily covered in “comfort” letters in connection with underwritten offerings and (iv) deliver such documents and certificates as may be reasonably requested by the Holders of a
majority in principal amount of the Registrable Securities being sold or the Underwriters, and which are customarily delivered in underwritten offerings, to evidence the continued validity of the representations and warranties of the Issuers made
pursuant to clause (i) above and to evidence compliance with any customary conditions contained in an underwriting agreement; and 
 (q) so long as any Registrable Securities remain outstanding, cause each Additional Guarantor upon the creation or acquisition by the Partnership of such Additional Guarantor, to execute a counterpart to
this Agreement in the form attached hereto as Annex A and to deliver such counterpart, together with an opinion of counsel as to the enforceability thereof against such entity if required by the Indenture, to the Initial Purchasers no later than
five Business Days following the execution thereof. 
 In the case of a Shelf Registration Statement, the Issuers may require
each Holder of Registrable Securities to furnish to the Issuers such information regarding such Holder and the proposed disposition by such Holder of such Registrable Securities as the Issuers may from time to time reasonably request in writing.

  
 13 

 In the case of a Shelf Registration Statement, each Holder of Registrable Securities agrees
that, upon receipt of any notice from the Issuers of the happening of any event of the kind described in Section 3(e)(iii) or 3(e)(v) hereof, such Holder will forthwith discontinue disposition of Registrable Securities pursuant to a
Registration Statement until such Holder’s receipt of the copies of the supplemented or amended Prospectus contemplated by Section 3(i) hereof and, if so directed by the Issuers, such Holder will deliver to the Issuers all copies in its
possession, other than permanent file copies then in such Holder’s possession, of the Prospectus covering such Registrable Securities that is current at the time of receipt of such notice. 

If the Issuers shall give any such notice to suspend the disposition of Registrable Securities pursuant to a Registration Statement, the
Issuers shall extend the period during which the Registration Statement shall be maintained effective pursuant to this Agreement by the number of days during the period from and including the date of the giving of such notice to and including the
date when the Holders shall have received copies of the supplemented or amended Prospectus necessary to resume such dispositions. The Issuers may give any such notice only twice during any 365-day period and any such suspensions shall not exceed 30
days for each suspension and there shall not be more than two suspensions in effect during any 365-day period. 
 The Holders of
Registrable Securities covered by a Shelf Registration Statement who desire to do so may sell such Registrable Securities in an Underwritten Offering. In any such Underwritten Offering, the investment bank or investment banks and manager or managers
(the “Underwriters”) that will administer the offering will be selected by the Majority Holders of the Registrable Securities included in such offering. 
 4. Participation of Broker-Dealers in Exchange Offer. (a) The Staff of the SEC has taken the position that any broker-dealer that receives Exchange Securities for its own account in the
Exchange Offer in exchange for Securities that were acquired by such broker-dealer as a result of market-making or other trading activities (a “Participating Broker-Dealer”) may be deemed to be an “underwriter” within the
meaning of the Securities Act and must deliver a prospectus meeting the requirements of the Securities Act in connection with any resale of such Exchange Securities. 
 The Issuers understand that it is the Staff’s position that if the Prospectus contained in the Exchange Offer Registration Statement includes a plan of distribution containing a statement to the
above effect and the means by which Participating Broker-Dealers may resell the Exchange Securities, without naming the Participating Broker-Dealers or specifying the amount of Exchange Securities owned by them, such Prospectus may be delivered by
Participating Broker-Dealers to satisfy their prospectus delivery obligation under the Securities Act in connection with resales of Exchange Securities for their own accounts, so long as the Prospectus otherwise meets the requirements of the
Securities Act. 

  
 14 

 (b) In light of the above, and notwithstanding the other provisions of this Agreement, the
Issuers agree to amend or supplement the Prospectus contained in the Exchange Offer Registration Statement, as would otherwise be contemplated by Section 3(i), for a period of up to 180 days after the last Exchange Date (as such period may be
extended pursuant to the penultimate paragraph of Section 3 of this Agreement), if requested by the Initial Purchasers or by one or more Participating Broker-Dealers, in order to expedite or facilitate the disposition of any Exchange Securities
by Participating Broker-Dealers consistent with the positions of the Staff recited in Section 4(a) above. The Issuers further agree that Participating Broker-Dealers shall be authorized to deliver such Prospectus during such period in
connection with the resales contemplated by this Section 4. 
 (c) The Initial Purchasers shall have no liability to any
Issuer, any Guarantor or any Holder with respect to any request that they may make pursuant to Section 4(b) above. 
 5.
Indemnification and Contribution. (a) Each Issuer and each Guarantor, jointly and severally, agrees to indemnify and hold harmless the Initial Purchasers and each Holder, their respective affiliates, directors and officers and each
Person, if any, who controls an Initial Purchasers or any Holder within the meaning of Section 15 of the Securities Act or Section 20 of the Exchange Act, from and against any and all losses, claims, damages and liabilities (including,
without limitation, legal fees and other expenses incurred in connection with any suit, action or proceeding or any claim asserted, as such fees and expenses are incurred), joint or several, that arise out of, or are based upon, (1) any untrue
statement or alleged untrue statement of a material fact contained in any Registration Statement or any Prospectus or any omission or alleged omission to state therein a material fact required to be stated therein or necessary in order to make the
statements therein, in the light of the circumstances under which they were made, not misleading, or (2) any untrue statement or alleged untrue statement of a material fact contained in any Prospectus, any Free Writing Prospectus used in
violation of this Agreement or any “issuer information” (“Issuer Information”) filed or required to be filed pursuant to Rule 433(d) under the Securities Act, or any omission or alleged omission to state therein 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, except insofar as such losses, claims, damages or liabilities arise out of, or are based upon, any untrue
statement or omission or alleged untrue statement or omission made in reliance upon and in conformity with any information relating to the Initial Purchasers or any Holder furnished to the Issuers in writing by the Initial Purchasers through Wells
Fargo Securities, LLC or any selling Holder expressly for use therein. In connection with any Underwritten Offering permitted by Section 3, the Issuers and the Guarantors, jointly and severally, will also indemnify the Underwriters, if any,
selling brokers, dealers and similar securities industry professionals participating in the distribution, their respective affiliates and each Person who controls such Persons (within the meaning of the Securities Act and the Exchange Act) to the
same extent as provided above with respect to the indemnification of the Holders, if requested in connection with any Registration Statement, any Prospectus, any Free Writing Prospectus or any Issuer Information. 

  
 15 

 (b) Each Holder agrees, severally and not jointly, to indemnify and hold harmless the
Issuers, the Guarantors, the Initial Purchasers and the other selling Holders, their respective affiliates, the directors of the Issuers, each officer of the Issuers who signed the Registration Statement and each Person, if any, who controls the
Issuers, the Guarantors, the Initial Purchasers and any other selling Holder within the meaning of Section 15 of the Securities Act or Section 20 of the Exchange Act to the same extent as the indemnity set forth in paragraph
(a) above, but only with respect to any losses, claims, damages or liabilities that arise out of, or are based upon, any untrue statement or omission or alleged untrue statement or omission made in reliance upon and in conformity with any
information relating to such Holder furnished to the Issuers in writing by such Holder expressly for use in any Registration Statement and any Prospectus. 
 (c) If any suit, action, proceeding (including any governmental or regulatory investigation), claim or demand shall be brought or asserted against any Person in respect of which indemnification may be
sought pursuant to either paragraph (a) or (b) above, such Person (the “Indemnified Person”) shall promptly notify the Person against whom such indemnification may be sought (the “Indemnifying Person”) in
writing; provided that the failure to notify the Indemnifying Person shall not relieve it from any liability that it may have under this Section 5 except to the extent that it has been materially prejudiced (through the forfeiture of
substantive rights or defenses) by such failure; and provided, further, that the failure to notify the Indemnifying Person shall not relieve it from any liability that it may have to an Indemnified Person otherwise than under this Section 5. If
any such proceeding shall be brought or asserted against an Indemnified Person and it shall have notified the Indemnifying Person thereof, the Indemnifying Person shall retain counsel reasonably satisfactory to the Indemnified Person to represent
the Indemnified Person and any others entitled to indemnification pursuant to this Section 5 that the Indemnifying Person may designate in such proceeding and shall pay the fees and expenses of such counsel related to such proceeding, as
incurred. In any such proceeding, any Indemnified Person shall have the right to retain its own counsel, but the fees and expenses of such counsel shall be at the expense of such Indemnified Person unless (i) the Indemnifying Person and the
Indemnified Person shall have mutually agreed to the contrary; (ii) the Indemnifying Person has failed within a reasonable time to retain counsel reasonably satisfactory to the Indemnified Person; (iii) the Indemnified Person shall have
reasonably concluded that there may be legal defenses available to it that are different from or in addition to those available to the Indemnifying Person; or (iv) the named parties in any such proceeding (including any impleaded parties)
include both the Indemnifying Person and the Indemnified Person and representation of both parties by the same counsel would be inappropriate due to actual or potential differing interests between them. It is understood and agreed that the
Indemnifying Person shall not, in connection with any proceeding or related proceeding in the same jurisdiction, be liable for the fees and expenses of more than one separate firm (in addition

  
 16 

 
to any local counsel) for all Indemnified Persons, and that all such fees and expenses shall be reimbursed as they are incurred. Any such separate firm (x) for the Initial Purchasers, their
affiliates, directors and officers and any control Persons of an Initial Purchaser shall be designated in writing by the Initial Purchasers, (y) for any Holder, its affiliates, directors and officers and any control Persons of such Holder shall
be designated in writing by the Majority Holders and (z) in all other cases shall be designated in writing by the Issuers. The Indemnifying Person shall not be liable for any settlement of any proceeding effected without its written consent,
but if settled with such consent or if there be a final judgment for the plaintiff, the Indemnifying Person agrees to indemnify each Indemnified Person from and against any loss or liability by reason of such settlement or judgment. Notwithstanding
the foregoing sentence, if at any time an Indemnified Person shall have requested that an Indemnifying Person reimburse the Indemnified Person for fees and expenses of counsel as contemplated by this paragraph, the Indemnifying Person 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 the Indemnifying Person of such request and (ii) the Indemnifying Person shall not
have reimbursed the Indemnified Person in accordance with such request prior to the date of such settlement. No Indemnifying Person shall, without the written consent of the Indemnified Person, effect any settlement of any pending or threatened
proceeding in respect of which any Indemnified Person is or could have been a party and indemnification could have been sought hereunder by such Indemnified Person, unless such settlement (A) includes an unconditional release of such
Indemnified Person, in form and substance reasonably satisfactory to such Indemnified Person, from all liability on claims that are the subject matter of such proceeding and (B) does not include any statement as to or any admission of fault,
culpability or a failure to act by or on behalf of any Indemnified Person. 
 (d) If the indemnification provided for in
paragraphs (a) and (b) above is unavailable to an Indemnified Person or insufficient in respect of any losses, claims, damages or liabilities referred to therein, then each Indemnifying Person under such paragraph, in lieu of indemnifying
such Indemnified Person thereunder, shall contribute to the amount paid or payable by such Indemnified Person as a result of such losses, claims, damages or liabilities (i) in such proportion as is appropriate to reflect the relative benefits
received by the Issuers and the Guarantors from the offering of the Securities and the Exchange Securities, on the one hand, and by the Holders from receiving Securities or Exchange Securities registered under the Securities Act, on the other hand,
or (ii) if the allocation provided by clause (i) is not permitted by applicable law, in such proportion as is appropriate to reflect not only the relative benefits referred to in clause (i) but also the relative fault of the Issuers
and the Guarantors on the one hand and the Holders on the other in connection with the statements or omissions that resulted in such losses, claims, damages or liabilities, as well as any other relevant equitable considerations. The relative fault
of the Issuers and the Guarantors on the one hand and the Holders on the other shall be determined by reference to, among other things, whether the untrue or alleged untrue statement of a material fact or the omission or alleged omission to state a
material fact relates to information supplied by the Issuers and the Guarantors or by the Holders and the parties’ relative intent, knowledge, access to information and opportunity to correct or prevent such statement or omission. 

  
 17 

 (e) The Issuers, the Guarantors and the Holders agree that it would not be just and
equitable if contribution pursuant to this Section 5 were determined by pro rata allocation (even if the Holders 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 paragraph (d) above. The amount paid or payable by an Indemnified Person as a result of the losses, claims, damages and liabilities referred to in paragraph (d) above shall be deemed to include,
subject to the limitations set forth above, any legal or other expenses incurred by such Indemnified Person in connection with any such action or claim. Notwithstanding the provisions of this Section 5, in no event shall a Holder be required to
contribute any amount in excess of the amount by which the total price at which the Securities or Exchange Securities sold by such Holder exceeds the amount of any damages that such Holder has otherwise been required to pay by reason of such untrue
or alleged untrue statement or omission or alleged omission. No Person guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the Securities Act) shall be entitled to contribution from any Person who was not guilty of
such fraudulent misrepresentation. The Holders’ obligations to contribute pursuant to this Section 5 are several and not joint. 
 (f) The remedies provided for in this Section 5 are not exclusive and shall not limit any rights or remedies that may otherwise be available to any Indemnified Person at law or in equity. 

(g) The indemnity and contribution provisions contained in this Section 5 shall remain operative and in full force and effect
regardless of (i) any termination of this Agreement, (ii) any investigation made by or on behalf of the Initial Purchasers or any Holder, their respective affiliates or any Person controlling any Initial Purchaser or any Holder, or by or
on behalf of the Issuers, their respective affiliates or the officers or directors of or any Person controlling the Issuers, (iii) acceptance of any of the Exchange Securities and (iv) any sale of Registrable Securities pursuant to a Shelf
Registration Statement. 
 6. General. 
 (a) No Inconsistent Agreements. The Issuers and the Guarantors represent, warrant and agree that (i) the rights granted to the Holders hereunder do not in any way conflict with and are not
inconsistent with the rights granted to the holders of any other outstanding securities issued or guaranteed by any Issuer or any Guarantor under any other agreement and (ii) neither any Issuer nor any Guarantor has entered into, or on or after
the date of this Agreement will enter into, any agreement that is inconsistent with the rights granted to the Holders of Registrable Securities in this Agreement or otherwise conflicts with the provisions hereof. 

  
 18 

 (b) Amendments and Waivers. The provisions of this Agreement, including the
provisions of this sentence, may not be amended, modified or supplemented, and waivers or consents to departures from the provisions hereof may not be given unless the Issuers have obtained the written consent of Holders of at least a majority in
aggregate principal amount of the outstanding Registrable Securities affected by such amendment, modification, supplement, waiver or consent; provided that no amendment, modification, supplement, waiver or consent to any departure from the
provisions of Section 5 hereof shall be effective as against any Holder of Registrable Securities unless consented to in writing by such Holder. Any amendments, modifications, supplements, waivers or consents pursuant to this Section 6(b)
shall be by a writing executed by each of the parties hereto. 
 (c) Notices. All notices and other communications
provided for or permitted hereunder shall be made in writing by hand-delivery, registered first-class mail, telex, telecopier, or any courier guaranteeing overnight delivery (i) if to a Holder, at the most current address given by such Holder
to the Issuers by means of a notice given in accordance with the provisions of this Section 6(c), which address initially is, with respect to the Initial Purchaser, the address set forth in the Purchase Agreement; (ii) if to the Issuers,
initially at the Issuers’ address set forth in the Purchase Agreement and thereafter at such other address, notice of which is given in accordance with the provisions of this Section 6(c); and (iii) to such other persons at their
respective addresses as provided in the Purchase Agreement and thereafter at such other address, notice of which is given in accordance with the provisions of this Section 6(c). All such notices and communications shall be deemed to have been
duly given at the time delivered by hand, if personally delivered; five Business Days after being deposited in the mail, postage prepaid, if mailed; when answered back, if telexed; when receipt is acknowledged, if telecopied; and on the next
Business Day if timely delivered to an air courier guaranteeing overnight delivery. Copies of all such notices, demands or other communications shall be concurrently delivered by the Person giving the same to the Trustee, at the address specified in
the Indenture. 
 (d) Successors and Assigns. This Agreement shall inure to the benefit of and be binding upon the
successors, assigns and transferees of each of the parties, including, without limitation and without the need for an express assignment, subsequent Holders; provided that nothing herein shall be deemed to permit any assignment, transfer or other
disposition of Registrable Securities in violation of the terms of the Purchase Agreement or the Indenture. If any transferee of any Holder shall acquire Registrable Securities in any manner, whether by operation of law or otherwise, such
Registrable Securities shall be held subject to all the terms of this Agreement, and by taking and holding such Registrable Securities such Person shall be conclusively deemed to have agreed to be bound by and to perform all of the terms and
provisions of this Agreement and such Person shall be entitled to receive the benefits hereof. The Initial Purchasers (in their capacity as the Initial Purchasers) shall have no liability or obligation to the Issuers or the Guarantors with respect
to any failure by a Holder to comply with, or any breach by any Holder of, any of the obligations of such Holder under this Agreement. 

  
 19 

 (e) Third Party Beneficiaries. Each Holder shall be a third party beneficiary to the
agreements made hereunder between the Issuers, on the one hand, and the Initial Purchasers, on the other hand, and shall have the right to enforce such agreements directly to the extent it deems such enforcement necessary or advisable to protect its
rights or the rights of other Holders hereunder. 
 (f) Counterparts. This Agreement may be executed in any number of
counterparts and by the parties hereto in separate counterparts, each of which when so executed shall be deemed to be an original and all of which taken together shall constitute one and the same agreement. 

(g) Headings. The headings in this Agreement are for convenience of reference only, are not a part of this Agreement and shall not
limit or otherwise affect the meaning hereof. 
 (h) Governing Law. This Agreement shall be governed by and construed in
accordance with the laws of the State of New York. 
 (i) Miscellaneous. This Agreement contains the entire agreement
between the parties relating to the subject matter hereof and supersedes all oral statements and prior writings with respect thereto. If any term, provision, covenant or restriction contained in this Agreement is held by a court of competent
jurisdiction to be invalid, void or unenforceable or against public policy, the remainder of the terms, provisions, covenants and restrictions contained herein shall remain in full force and effect and shall in no way be affected, impaired or
invalidated. The Issuers and the Initial Purchasers shall endeavor in good faith negotiations to replace the invalid, void or unenforceable provisions with valid provisions the economic effect of which comes as close as possible to that of the
invalid, void or unenforceable provisions. 

  
 20 

 IN WITNESS WHEREOF, the parties have executed this Agreement as of the date first written
